Immunogenicity of Pneumococcal Vaccine in Renal Transplant Recipients,Three Year Follow-up of a Randomized Trial

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 3 2007
D. Kumar
Routine pneumococcal vaccination is recommended at regular intervals posttransplant. However, there is limited data on durability of vaccine response and the impact of vaccine type on antibody persistence. We determined the durability of response for patients enrolled in a randomized trial of conjugate (PCV7) versus polysaccharide (PPV23) pneumococcal vaccination. Response was defined as a twofold increase from baseline and a titer ,0.35 ,g/mL using a pneumococcal ELISA for seven serotypes (measured at 8 weeks and 3 years). Forty-seven patients were evaluated and had received either PPV23 (n = 24) or PCV7 (n = 23). Response rates and geometric mean titers varied by serotype but declined significantly at 3-years for 6 of 7 serotypes (p < 0.001). No significant difference in durability was found in patients that had received PPV23 versus PCV7. Compared to the 8-week response, 20.6% fewer patients had a response to at least one serotype by 3 years. The largest relative declines were seen for serotype 4 (response dropped from 40.4% at 8 weeks to 17.0% at 3 years) and serotype 9V (44.7% dropping to 21.3%). The only factor predictive of response durability was a strong multiserotype initial response (p < 0.001). In conclusion, vaccine responses decline significantly by 3 years and conjugate vaccine does not improve the durability of response. [source]


Criminal Behavior in Antisocial Substance Abusers between Five and Fifteen Years Follow-Up

THE AMERICAN JOURNAL ON ADDICTIONS, Issue 1 2007
Mats Fridell PhD
Antisocial personality disorder (ASPD) is one of the most common co-occurring disorders in substance abusers, characterized among other things by a high propensity for criminal actions. A cohort of 125 substance abusers were followed in a longitudinal design. Patients were diagnosed with ASPD at an index treatment episode, interviewed at five-year follow-up, and followed-up through the Swedish criminal justice register by 2005 for the years 1995,2003. ASPD and non-ASPD subjects were compared using Mann Whitney U test for ordinal variables (number of offenses and months in prison) and chi-square tests for categorical variables. A total of 107 were alive by 1995, when the period of observation began. ASPD diagnosed at baseline was related to criminal offenses and incarceration during the follow-up from 5 to 15 years. For most categories, ASPD diagnosis was associated with higher frequency of offense. An ASPD diagnosis based on SCID-II interview made at five-year follow-up was related to the number of offenses but unrelated to incarceration. In a sample of drug abusers, ASPD was associated with high levels of criminal behavior, even years after the diagnosis was given. A diagnosis based on clinical observation during treatment was at least as predictive of criminal behavior as a diagnosis based on a SCID-II interview. [source]


Non-invasive bioengineering methods in an intervention study in 1020 male metal workers: results and implications for occupational dermatology

CONTACT DERMATITIS, Issue 5 2010
Birgitta Kütting
Background: Measurements of transepidermal water loss (TEWL) as an indicator of skin barrier function and colorimetry for quantifying erythema have been recommended for monitoring persons at risk of occupational hand dermatitis. Objective: This study examines the practicability and usefulness of biophysical measurements at the workplace. Patients/Material/Methods: A sample of 1020 male metal workers was enrolled; 800 participants were followed up for 1 year. TEWL results and colorimetry (a* value), respectively, were used as effectiveness outcomes, comparing the findings in the four study arms (skin care, skin protection, both combined, and control group). Results: At 1 year follow-up, the TEWL was slightly but significantly lower in the group of participants randomized for application of barrier cream alone, indicating a protective effect. However, addressing both the individual absolute change of a* value and the differences of TEWL (delta-TEWL) of the dominant hand over the study period, no significant difference was found between the four groups. Conclusions: Dermatological examinations at the workplace cannot be replaced by bioengineering techniques. The supplementary benefit is apparently low, possibly because of difficulties in achieving standardized measurement conditions and other technical reasons. [source]

Opjordsmoen S, Friis S, Melle I, Haahr U, Johannessen JO, Larsen TK, Røssberg JI, Rund BR, Simonsen E, Vaglum P, McGlashan TH. A 2-year follow-up of involuntary admission's influence upon adherence and outcome in first-episode psychosis. Objective:, To see, if voluntary admission for treatment in first-episode psychosis results in better adherence to treatment and more favourable outcome than involuntary admission. Method:, We compared consecutively first-admitted, hospitalised patients from a voluntary (n = 91) with an involuntary (n = 126) group as to psychopathology and functioning using Positive and Negative Syndrome Scale and Global Assessment of Functioning Scales at baseline, after 3 months and at 2 year follow-up. Moreover, duration of supportive psychotherapy, medication and number of hospitalisations during the 2 years were measured. Results:, More women than men were admitted involuntarily. Voluntary patients had less psychopathology and better functioning than involuntary patients at baseline. No significant difference as to duration of psychotherapy and medication between groups was found. No significant difference was found as to psychopathology and functioning between voluntarily and involuntarily admitted patients at follow-up. Conclusion:, Legal admission status per se did not seem to influence treatment adherence and outcome. [source]


Insight in early psychosis: a 1 year follow-up

ACTA PSYCHIATRICA SCANDINAVICA, Issue 2002
A. Mintz
Insight is an important prognostic indicator in early psychosis, as its presence can enhance treatment compliance, thus reducing the risk of clinical deterioration. The Calgary Early Psychosis Programme (EPP) is a comprehensive treatment programme for individuals experiencing their first episode of psychosis. Purpose, (i) to examine insight on admission and determine if change occurred in the first year of treatment and (ii) to determine if insight was associated with other symptoms. Methods, Participants were 180 consecutive admissions to EPP who completed a 1-year follow-up. Insight, positive and negative symptoms were measured with the PANSS. Depression was measured with the Calgary Depression Scale. Results, There was a significant improvement in insight from initial to 1-year follow-up (P < 0.001). Insight was positively correlated with positive and negative symptoms (P < 0.001) over time. Insight was negatively correlated with depression (P < 0.001) at the initial assessment. Conclusions, In these first episode patients, there is a significant improvement in insight over time. Insight is significantly related to positive and negative symptoms and to depression in the initial stages of the illness when the presence of depression is notable. [source]


Neuronal Disconnection for the Surgical Treatment of Pediatric Epilepsy

EPILEPSIA, Issue 2000
Hiroyuki Shimizu
Summary: The surgical methods and results of disconnective surgery for pediatric epilepsy were retrospectively analyzed. The techniques of neuronal disconnection included multiple subpial resection (MST), corpus callosotomy, and functional hemisphercctomy by disconnection. Of 158 total pediatric operations, disconnective techniques were employed in more than 60% of the cases. MST was applied when the epileptic focus was located in unresectable cortices such as speech or motor areas. MST was also instrumental when the epileptogenic zone was extensive and was widely disseminated, as is often observed in cases of neocortical epilepsy. Of 25 patients who underwent MST, surgical outcomes after > 1 year follow-up showed Engel Class I or II in 10 cases, Class III in 12, and Class IV in 3. No mortality or morbidity was encountered during surgery or postoperatively. Corpus callosotomy was applied to cases of disabling generalized seizures and showed a marked effect in alleviating potentially injurious drop attacks. Of 34 patients with drop attacks, 29 became free from this type of seizure, 4 had infrequent attacks, and only 1 showed no beneficial effect. Postoperative improvement of cognition and speech was recognized in 77% of the cases. We developed a new method of functional hemispherectomy by fiber disconnection and applied this less invasive technique to 23 cases of hemispheric lesions. Of the 17 cases with > 1 year follow-up, 13 were in Class I or II, and 3 in Class III, and 2 in Class IV. Development partially normalized in infants with good seizure outcomes. [source]


The National Treatment Outcome Research Study (NTORS): 4,5 year follow-up results

ADDICTION, Issue 3 2003
Michael Gossop
ABSTRACT Aims ,The National Treatment Outcome Research Study (NTORS) is the first prospective national study of treatment outcome among drug misusers in the United Kingdom. NTORS investigates outcomes for drug misusers treated in existing services in residential and community settings. Design, setting and participants,The study used a longitudinal, prospective cohort design. Data were collected by structured interviews at intake to treatment, 1 year, 2 years and at 4,5 years. The sample comprised 418 patients from 54 agencies and four treatment modalities. Measurements, Measures were taken of illicit drug use, injecting and sharing injecting equipment, alcohol use, psychological health and crime. Findings, Rates of abstinence from illicit drugs increased after treatment among patients from both residential and community (methadone) programmes. Reductions were found for frequency of use of heroin, non-prescribed methadone, benzodiazepines, injecting and sharing of injecting equipment. For most variables, reductions were evident at 1 year with outcomes remaining at about the 1 year level or with further reductions. Crack cocaine and alcohol outcomes at 4,5 years were not significantly different from intake. Conclusions, Substantial reductions across a range of problem behaviours were found 4,5 years after patients were admitted to national treatment programmes delivered under day-to-day conditions. The less satisfactory outcomes for heavy drinking and use of crack cocaine suggest the need for services to be modified to tackle these problems more effectively. Despite differences between the United Kingdom and the United States in patient populations and in treatment programmes, there are many similarities between the two countries in outcomes from large-scale, multi-site studies.

Late sensory function after intraoperative capsaicin wound instillation

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 2 2010
E. K. AASVANG
Background: Intense capsaicin-induced C-fiber stimulation results in reversible lysis of the nerve soma, thereby making capsaicin wound instillation of potential interest for the treatment of post-operative pain. Clinical histological and short-term sensory studies suggest that the C-fiber function is partly re-established after skin injection of capsaicin. However, no study has evaluated the long-term effects of wound instillation of purified capsaicin on sensory functions. Methods: Patients included in a double-blind placebo-controlled randomized study of the analgesic effect of capsaicin after groin hernia repair were examined by quantitative sensory testing before, 1 week and 2 years post-operatively. The primary endpoint was occurrence of hyperalgesia/allodynia. The secondary endpoints were acute and late sensory changes between the two patient groups. Patients were blinded to the allocated treatment. Results: Twenty (100%) capsaicin and 16 (76%) placebo-treated patients were seen at the year follow-up. Hyperalgesia was seen in five capsaicin- vs. one placebo-treated patient (P=0.2). The mechanical detection threshold was significantly increased on the operated side in the capsaicin vs. placebo group at the 1-week follow-up (P<0.05), but was not different at the year follow-up (P=0.3). There were no other significant differences in sensory function on the operated side between groups at the pre-operative, 1-week or year post-operative follow-up (P>0.05). The sensory function on the contralateral side was comparable between groups throughout the study (P>0.1). Conclusion: This small-volume study calls for further long-term safety studies of wound capsaicin instillation. [source]


Long-Term Outcome of Atrial Fibrillation Ablation: Impact and Predictors of Very Late Recurrence

JOURNAL OF CARDIOVASCULAR ELECTROPHYSIOLOGY, Issue 10 2010
ANITA WOKHLU M.D.
Long-Term Outcome of AF Ablation. Introduction: Ablation eliminates atrial fibrillation (AF) in studies with 1 year follow-up, but very late recurrences may compromise long-term efficacy. In a large cohort, we sought to describe the determinants of delayed recurrence after AF ablation. Methods and Results: Seven hundred and seventy-four patients with AF (428 paroxysmal [PAF, 55%] and 346 persistent or longstanding persistent [PersAF, 45%]) underwent wide area circumferential ablation (WACA, 62%) or pulmonary vein isolation (38%). Over 3.0 ± 1.9 years, there were 135 recurrences in PAF patients and 142 in PersAF patients. AF elimination was achieved in 61% of patients with PersAF at 2 years after last ablation and in 71% of patients with PAF (P = 0.04). This finding was related to a higher initial rate of very late recurrence in PersAF. From 1.0 to 2.5 years, the recurrence increased by 20% (from 37% to 57%) in PersAF patients versus only 12% (from 27% to 39%) in PAF patients. Independent predictors of overall recurrence included diabetes (HR 1.9 [1.3,2.9], P = 0.002) and PersAF (HR 1.6 [1.2,2.0], P < 0.001). Independent predictors of very late recurrence included PersAF (HR 1.7 [1.1,2.7], P = 0.018) and WACA (HR 1.8 [1.1,2.7], P = 0.018), while diabetes came close to significance. In PAF patients, left atrial size >45 mm was identified as an AF-type specific predictor (HR 2.4 [1.3,4.7], P = 0.009), whereas in PersAF patients, no unique predictors were identified. Conclusion: Late recurrences reduced the long-term efficacy of AF ablation, particularly in patients with PersAF and underlying cardiovascular diseases.

Percutaneous Mitral Valve Repair for Mitral Regurgitation

JOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 1 2003
PETER C. BLOCK M.D.
Mitral regurgitation (MR) associated with, ischemic, and degenerative (prolapse) disease, contributes to left ventricular (LV) dysfunction due to remodeling, and LV dilation, resulting in worsening of MR. Mitral valve (MV) surgical repair has provided improvement in survival, LV function and symptoms, especially when performed early. Surgical repair is complex, due to diverse etiologies and has significant complications. The Society for Thoracic Surgery database shows that operative mortality for a 1st repair is 2% and for re-do repair is 4 times that. Cardiopulmonary bypass and cardiac arrest are required. The attendant morbidity prolongs hospitalization and recovery. Alfieri simplified mitral repair using an edge-to-edge technique which subsequently has been shown to be effective for multiple etiologies of MR. The MV leaflers are typically brought together by a central suture producing a double orifice MV without stenosis. Umana reported that MR decreased from grade 3.6 +/,0.5 to0.8 +/,0.4 (P < 0.0001)and LV ejection fraction increased from 33 +/,13% to 45 +/,11%(P = 0.0156). In 121 patients, Maisano reported freedom from re-operation of 95 +/,4.8% with up to 6 year follow-up. Oz developed a MV "grasper" that is directly placed via a left ventriculotomy and coapts both leaflets which are then fastened by a graduated spiral screw. An in-vitro model using explanted human valves showed significant reduction in MR and in canine studies, animals followed by serial echo had persistent MV coaptation. At 12 weeks the device was endothelialized. These promising results have paved the way for a percutaneous or minimally invasive off pump mitral repair. Evalve has developed catheter-based technology, which, by apposing the edges of a regurgitant MV, results in edge-to-edge repair. Release of the device is done after echo and fluoroscopic evaluation under normal loading conditions. If the desired effect is not produced the device can be repositioned or retrieved. Animal studies show excellent healing, with incorporation of the device into the leaflets at 6,10 weeks with persistent coaptation. Another percutaneous approach has been to utilize the proximity of the coronary sinus (CS) to the mitral annulus (MA). Placement of a self-compressing device in the CS along the region of the posterior MA has, in canine models, reduced MR and addresses the issues of MA dilation and its contribution to MR. Ongoing studies are underway for both techniques. (J Interven Cardiol 2003;16:93,96) [source]


Characterization of viral kinetics in patients with hepatitis B e antigen-positive chronic hepatitis B

JOURNAL OF MEDICAL VIROLOGY, Issue 6 2007
I-Chin Wu
Abstract A study was conducted during a 1 year follow-up to characterize the viral kinetics in hepatitis B e antigen (HBeAg)-positive chronic hepatitis B and to develop a model of predicting the probability of spontaneous HBeAg seroconversion. Fifty-seven patients with HBeAg-positive chronic hepatitis B were enrolled with monthly follow-ups from three Phase III clinical trial placebo groups. According to serial viral loads, 30 patients (52.6%) with the stationary pattern maintained stable HBV DNA levels with fluctuations of less than 1.5 log copies/ml. Twenty patients (35.1%) with the declining pattern exhibited a spontaneous decline of more than 1.5 log copies/ml without a following rebound of at least 1.5 log copies/ml. The remaining seven patients (12.3%) had the wavering pattern. Both declining and wavering patterns, when compared with the stationary pattern, had significantly higher hepatic necroinflammation in terms of ALT and Knodell scores at the baseline and peak ALT levels during the follow-up period. The declining pattern had a significantly better clinical outcome in terms of the lowest final HBV DNA and a reduction in the necroinflammatory score after 1 year. Furthermore, the declining pattern had a favorable HBeAg seroconversion rate (40%) compared with the wavering (14.3%) and stationary patterns (0%). A regression equation, incorporating simultaneous serum bilirubin, ALT, and HBV DNA levels, predicted the probability of HBeAg seroconversion with a sensitivity of 76.8% and a specificity of 74.7%. In conclusion, different viral kinetic patterns in patients with chronic hepatitis B implicate distinct clinical significance and immunologic perspective. J. Med.

Uncommon dermoid cyst presented in the mandible possibly originating from embryonic epithelial remnants

JOURNAL OF ORAL PATHOLOGY & MEDICINE, Issue 3 2002
Kazuo Komiyama
Abstract A case of an intraosseous dermoid cyst that had developed in the mandible of a 29-year-old-male is reported. The patient was admitted to our dental clinic complaining of pain in the right molar area of the mandible. The patient had no particular history of the present illness. A radiographic examination revealed diffuse bone absorption in the right molar area. A biopsy showed the lesion to be an intraosseous dermoid cyst which was surgically enucleated. Microscopic examination of the excised tissue showed it to be well circumscribed with fibrous tissues, and the cystic space lined by keratinized epithelium. In addition, sweat glands and hair follicle-like skin appendages were identified in the cystic wall, where a daughter cyst was also found. We suggested that this uncommon cyst had developed in the mandible, as a result of embryonic epithelium migration. The patient remained in good health during the three year follow-up. [source]


A Comparison of Correlates of DSM-IV Alcohol Abuse or Dependence Among More Than 400 Sons of Alcoholics and Controls

ALCOHOLISM, Issue 1 2001
M. A. Schuckit
Background: Alcohol dependence and abuse are defined as separate disorders. However, relatively few data are available about whether the same characteristics predict both syndromes. Methods: Complete data were available from the 15 year follow-up of 411 men who originally had been evaluated from a university population at about age 20. Both baseline data gathered prospectively and the retrospective ratings in six domains of life functioning were analyzed for their relationship to the development of alcohol abuse or dependence during the follow-up. Results: Baseline characteristics of a family history of substance use disorders, the quantity and frequency of drinking, the history of alcohol-related problems, and the level of response to alcohol all predicted future alcohol abuse or dependence, but only an alcoholic second-degree relative or a first-degree drug-dependent family member differentially predicted dependence. Logistic regression analyses revealed that similar baseline characteristics combined to predict dependence and, separately, abuse. When the domains of functioning during the 15 years were included, positive alcohol expectancies, poor coping mechanisms, low level of social support, and drinking in the environment contributed to both dependence and abuse, although the relationship was stronger for dependence. Conclusions: The predictors and correlates of alcohol abuse and dependence in this group of men were similar. Further research in additional populations and on other drugs is needed to determine if the two syndromes overlap sufficiently to be combined. [source]


Is the Cost of Adult Living Donor Liver Transplantation Higher Than Deceased Donor Liver Transplantation?

LIVER TRANSPLANTATION, Issue 3 2004
Mark W. Russo MD
Background An important long-term consideration for living-donor liver transplantation (LDLT) is the expense compared with cadaveric-liver transplantation. LDLT is a more complex procedure than cadaveric transplantation and the cost of donor evaluation, donor surgery, and postoperative donor care must be included in a cost analysis for LDLT. In this study, we compare the comprehensive cost of LDLT with that of cadaveric-liver transplantation. Methods All costs for medical services provided at our institution were recorded for 24 LDLT and 43 cadaveric recipients with greater than 1 year follow-up transplanted between August 1997 and April 2000. The donor costs include donors evaluated and rejected, donors evaluated and accepted, donor right hepatectomy costs, and donor follow-up costs (365 days postdonation). LDLT and cadaveric recipient costs include medical care 90 days pre-LDLT, recipient transplant costs, and recipient follow-up costs (365 days posttransplant) including retransplantation. Cost is expressed as an arbitrary cost unit (CU) that is a value between $500 to $1,500. Results Total LDLT costs (evaluations of rejected donors + evaluations of accepted donors + donor hepatectomy + donor follow-up care for 1 year + pretransplant recipient care [90 days pretransplant] + recipient transplantation + recipient 1-year posttransplant care)= 162.7 CU. Total mean cadaveric transplant costs (pretransplant recipient care [90 days pretransplant] + recipient transplantation [including organ acquisition cost] + recipient 1-year posttransplant care)=134.5 CU, (P = ns) Conclusions The total comprehensive cost of LDLT is 21% higher than cadaveric transplantation, although this difference is not significant.

Long-term results of a multicenter study on subthalamic and pallidal stimulation in Parkinson's disease,

MOVEMENT DISORDERS, Issue 5 2010
Elena Moro MD
Abstract We report the 5 to 6 year follow-up of a multicenter study of bilateral subthalamic nucleus (STN) and globus pallidus internus (GPi) deep brain stimulation (DBS) in advanced Parkinson's disease (PD) patients. Thirty-five STN patients and 16 GPi patients were assessed at 5 to 6 years after DBS surgery. Primary outcome measure was the stimulation effect on the motor Unified Parkinson's Disease Rating Scale (UPDRS) assessed with a prospective cross-over double-blind assessment without medications (stimulation was randomly switched on or off). Secondary outcomes were motor UPDRS changes with unblinded assessments in off- and on-medication states with and without stimulation, activities of daily living (ADL), anti-PD medications, and dyskinesias. In double-blind assessment, both STN and GPi DBS were significantly effective in improving the motor UPDRS scores (STN, P < 0.0001, 45.4%; GPi, P = 0.008, 20.0%) compared with off-stimulation, regardless of the sequence of stimulation. In open assessment, both STN- and GPi-DBS significantly improved the off-medication motor UPDRS when compared with before surgery (STN, P < 0.001, 50.5%; GPi, P = 0.002, 35.6%). Dyskinesias and ADL were significantly improved in both groups. Anti-PD medications were significantly reduced only in the STN group. Adverse events were more frequent in the STN group. These results confirm the long-term efficacy of STN and GPi DBS in advanced PD. Although the surgical targets were not randomized, there was a trend to a better outcome of motor signs in the STN-DBS patients and fewer adverse events in the GPi-DBS group. © 2010 Movement Disorder Society [source]

The risks and benefits of long-term use of hydroxyurea in sickle cell anemia: A 17.5 year follow-up,,§¶,,,,,§§

AMERICAN JOURNAL OF HEMATOLOGY, Issue 6 2010
Martin H. Steinberg
A randomized, controlled clinical trial established the efficacy and safety of short-term use of hydroxyurea in adult sickle cell anemia. To examine the risks and benefits of long-term hydroxyurea usage, patients in this trial were followed for 17.5 years during which they could start or stop hydroxyurea. The purpose of this follow-up was to search for adverse outcomes and estimate mortality. For each outcome and for mortality, exact 95% confidence intervals were calculated, or tests were conducted at , = 0.05 level (P -value <0.05 for statistical significance). Although the death rate in the overall study cohort was high (43.1%; 4.4 per 100 person-years), mortality was reduced in individuals with long-term exposure to hydroxyurea. Survival curves demonstrated a significant reduction in deaths with long-term exposure. Twenty-four percent of deaths were due to pulmonary complications; 87.1% occurred in patients who never took hydroxyurea or took it for <5 years. Stroke, organ dysfunction, infection, and malignancy were similar in all groups. Our results, while no longer the product of a randomized study because of the ethical concerns of withholding an efficacious treatment, suggest that long-term use of hydroxyurea is safe and might decrease mortality.

Follow-Up Recommendations for Benign Breast Biopsies

THE BREAST JOURNAL, Issue 5 2006
Susanna Shin MD
Abstract: Histologically proven benign breast disease increases a woman's relative risk for subsequent cancer development. Yet follow-up guidelines for mammogram and clinical breast examination after a benign breast biopsy are lacking. Our objective was to determine if increased surveillance is indicated following a benign breast biopsy. Following institutional review board approval, a retrospective database review was conducted of prospectively gathered patients who had a benign breast biopsy (core or excisional) for an abnormality detected on mammogram, ultrasound, or clinical breast examination. Follow-up, for all subjects, was a clinical breast examination and mammogram or ultrasound at 6 months, 1 year, and 2 years after benign breast biopsy by a breast surgeon. End points were the need for additional biopsies or cancer detection. Statistical analysis was performed using chi-squared analysis. From January 2000 to July 2003, 156 patients age 18,86 years had a benign breast biopsy. During the 2 year follow-up, 20 patients (13%) required a subsequent biopsy. No significant difference was observed in mean age, race, menarche, menopause, parity, age at first live birth, use of oral contraceptives, history of prior biopsy, or the pathology of the initial lesion between those who needed a subsequent biopsy and those who did not. Seven excisional biopsies were performed (one at 6 months, four at 1 year, and two at 2 years follow-up) for growth of the benign breast biopsy lesion, and pathology remained concordant with the original diagnosis. Thirteen biopsies were done for new findings on mammogram or ultrasound. Three of these (1.9%) yielded a cancer diagnosis (one at 6 months, one at 1 year, and one at 2 years follow-up). No new lesions were identified on follow-up by clinical breast examination alone. Increased surveillance following a benign breast biopsy is necessary because of the increased need for subsequent biopsy or risk of cancer development. This should include imaging (mammography or ultrasound) and a clinical breast examination 6 months, 1 year, and 2 years after a benign breast biopsy. [source]


Inpatient treatment in child and adolescent psychiatry , a prospective study of health gain and costs

THE JOURNAL OF CHILD PSYCHOLOGY AND PSYCHIATRY AND ALLIED DISCIPLINES, Issue 12 2007
Jonathan Green
Background:, Inpatient treatment is a complex intervention for the most serious mental health disorders in child and adolescent psychiatry. This is the first large-scale study into its effectiveness and costs. Previous studies have been criticised for methodological weaknesses. Methods:, A prospective cohort study, including economic evaluation, conducted in 8 UK units (total n = 150) with one year follow-up after discharge. Patients acted as their own controls. Outcome measurement was the clinician-rated Childhood Global Assessment Scale (CGAS); researcher-rated health needs assessment; parent- and teacher-rated symptomatology. Results:, We found a significant (p < .001) and clinically meaningful 12-point improvement in CGAS following mean 16.6 week admission (effect size .92); this improvement was sustained at 1 year follow-up. Comparatively, during the mean 16.4 week pre-admission period there was a 3.7-point improvement (effect size .27). Health needs assessment showed similar gain (p < .001, effect size 1.25), as did teacher- and parent-rated symptoms. Improvement was found across all diagnoses. Longer stays, positive therapeutic alliance and better premorbid family functioning independently predicted better outcome. Mean cost of admission was £24,100; pre-admission and post-discharge support costs were similar. Conclusions:, Inpatient treatment is associated with substantive sustained health gain across a range of diagnoses. Lack of intensive outpatient-treatment alternatives limits any unqualified inference about causal effects, but the rigour of measurement here gives the strongest indication to date of the positive impact of admission for complex mental health problems in young people.

Erectile Function Recovery Rate after Radical Prostatectomy: A Meta-Analysis

THE JOURNAL OF SEXUAL MEDICINE, Issue 9 2009
Raanan Tal MD
ABSTRACT Introduction., Erectile function recovery (EFR) rates after radical prostatectomy (RP) vary greatly based on a number of factors, such as erectile dysfunction (ED) definition, data acquisition means, time-point postsurgery, and population studied. Aim., To conduct a meta-analysis of carefully selected reports from the available literature to define the EFR rate post-RP. Main Outcome Measures., EFR rate after RP. Methods., An EMBASE and MEDLINE search was conducted for the time range 1985,2007. Articles were assessed blindly by strict inclusion criteria: report of EFR data post-RP, study population ,50 patients, ,1 year follow-up, nerve-sparing status declared, no presurgery ED, and no other prostate cancer therapy. Meta-analysis was conducted to determine the EFR rate and relative risks (RR) for dichotomous subgroups. Results., A total of 212 relevant studies were identified; only 22 (10%) met the inclusion criteria and were analyzed (9,965 RPs, EFR data: 4,983 subjects). Mean study population size: 226.5, standard deviation = 384.1 (range: 17,1,834). Overall EFR rate was 58%. Single center series publications (k = 19) reported a higher EFR rate compared with multicenter series publications (k = 3): 60% vs. 33%, RR = 1.82, P = 0.001. Studies reporting ,18-month follow-up (k = 10) reported higher EFR rate vs. studies with <18-month follow-up (k = 12), 60% vs. 56%, RR = 1.07, P = 0.02. Open RP (k = 16) and laparoscopic RP (k = 4) had similar EFR (57% vs. 58%), while robot-assisted RP resulted in a higher EFR rate (k = 2), 73% compared with these other approaches, P = 0.001. Patients <60 years old had a higher EFR rate vs. patients ,60 years, 77% vs. 61%, RR = 1.26, P = 0.001. Conclusions., These data indicate that most of the published literature does not meet strict criteria for reporting post-RP EFR. Single and multiple surgeon series have comparable EFR rates, but single center studies have a higher EFR. Younger men have higher EFR and no significant difference in EFR between ORP and LRP is evident. Tal R, Alphs HH, Krebs P, Nelson CJ, and Mulhall JP.

Peritoneal T Cell Responses Can Be Polarized Toward Th1 or Th2 in Children on Chronic Peritoneal Dialysis

ARTIFICIAL ORGANS, Issue 8 2004
Sabrina Chiesa
Abstract:, Peritoneal T cell responses can be polarized toward Th1 or Th2 in children on chronic peritoneal dialysis. Previous studies on the peritoneal immune system described the presence of activated T lymphocytes in peritoneal effluents from subjects on chronic peritoneal dialysis (CPD). Since Th1/Th2 polarized response can influence the outcome of specific infectious diseases, we investigated if activated Th1/Th2 cells can be detected in peritoneal effluents during peritoneal dialysis, in order to better understand the role of T cells in the mechanisms of peritoneal defense. We have studied 8 children (4 males, 4 females, mean age 5.8 ± 5.7 years, range 0.3,13.4) on CPD. Peritoneal cells have been isolated from peritoneal effluents by centrifugation. Immunofluorescent staining of intracellular cytokines for flow cytometric analysis was used to detect the percentage of T cells producing either IFN-, (Th1) or IL-4 (Th2). In the initial study 3 months after CPD initiation, high percentages of IFN-, positive peritoneal T cells (38% and 63%) were detected in two subjects; this finding is consistent with a Th1 polarization of peritoneal T cells. In another subject, high percentages of IL-4 positive T cells (31%) were detected, suggesting a Th2 polarization of peritoneal T cell response. Small amounts of either Th1 or Th2 T cells (2,4%) were also detected in the other subjects. At the 1 year follow-up, Th1 polarization persisted in one subject (18% IFN-, positive peritoneal T cells), in another a shift from Th1 to Th2 was observed, and in the other subject a down regulation of both T cell subsets occurred. The finding that a predominance of T cells producing either IFN-, or IL-4 was found in 3 out of 8 children strongly suggests that peritoneal T cell responses can be polarized toward Th1 or Th2. The decrease of Th1 and/or Th2 polarized T cells in the peritoneum of 4 out of 6 subjects (after 1 year) suggests that CPD can play an immunosuppressive role on T cell peritoneal responses. Further studies are needed in order to define whether different T helper activation patterns are associated with a higher risk of peritoneal infection or of peritoneal damage. [source]


Enamel matrix derivative (Emdogain®) for periodontal tissue regeneration in intrabony defects

AUSTRALIAN DENTAL JOURNAL, Issue 1 2010
M Esposito
Background:, Periodontitis is a chronic infective disease of the gums caused by bacteria present in dental plaque. This condition induces the breakdown of the tooth supporting apparatus until teeth are lost. Surgery may be indicated to arrest disease progression and regenerate lost tissues. Several surgical techniques have been developed to regenerate periodontal tissues including guided tissue regeneration (GTR), bone grafting (BG) and the use of enamel matrix derivative (EMD). EMD is an extract of enamel matrix and contains amelogenins of various molecular weights. Amelogenins are involved in the formation of enamel and periodontal attachment formation during tooth development. Objectives:, To test whether EMD is effective, and to compare EMD versus GTR, and various BG procedures for the treatment of intrabony defects. Search strategy:, We searched the Cochrane Oral Health Group Trials Register, CENTRAL, MEDLINE and EMBASE. Several journals were handsearched. No language restrictions were applied. Authors of randomized controlled trials (RCTs) identified, personal contacts and the manufacturer were contacted to identify unpublished trials. Most recent search: February 2009. Selection criteria:, RCTs on patients affected by periodontitis having intrabony defects of at least 3 mm treated with EMD compared with open flap debridement, GTR and various BG procedures with at least 1 year follow-up. The outcome measures considered were: tooth loss, changes in probing attachment levels (PAL), pocket depths (PPD), gingival recessions (REC), bone levels from the bottom of the defects on intraoral radiographs, aesthetics and adverse events. The following time-points were to be evaluated: 1, 5 and 10 years. Data collection and analysis:, Screening of eligible studies, assessment of the methodological quality of the trials and data extraction were conducted in duplicate and independently by two authors. Results were expressed as random-effects models using mean differences for continuous outcomes and risk ratios (RR) for dichotomous outcomes with 95% confidence intervals (CI). It was decided not to investigate heterogeneity, but a sensitivity analysis for the risk of bias of the trials was performed. Main results:, Thirteen trials were included out of 35 potentially eligible trials. No included trial presented data after 5 years of follow-up, therefore all data refer to the 1-year time point. A meta-analysis including nine trials showed that EMD treated sites displayed statistically significant PAL improvements (mean difference 1.1 mm, 95% CI 0.61 to 1.55) and PPD reduction (0.9 mm, 95% CI 0.44 to 1.31) when compared to placebo or control treated sites, though a high degree of heterogeneity was found. Significantly more sites had <2 mm PAL gain in the control group, with RR 0.53 (95% CI 0.34 to 0.82). Approximately nine patients needed to be treated (NNT) to have one patient gaining 2 mm or more PAL over the control group, based on a prevalence in the control group of 25%. No differences in tooth loss or aesthetic appearance as judged by the patients were observed. When evaluating only trials at a low risk of bias in a sensitivity analysis (four trials), the effect size for PAL was 0.62 mm (95% CI 0.28 to 0.96), which was less than 1.1 mm for the overall result. Comparing EMD with GTR (five trials), GTR showed statistically significant more postoperative complications (three trials, RR 0.12, 95% CI 0.02 to 0.85) and more REC (0.4 mm 95% CI 0.15 to 0.66). The only trial comparing EMD with a bioactive ceramic filler found statistically significant more REC (-1.60 mm, 95% CI ,2.74 to ,0.46) at the EMG treated sites. Authors' conclusions:, One year after its application, EMD significantly improved PAL levels (1.1 mm) and PPD reduction (0.9 mm) when compared to a placebo or control, however, the high degree of heterogeneity observed among trials suggests that results have to be interpreted with great caution. In addition, a sensitivity analysis indicated that the overall treatment effect might be overestimated. The actual clinical advantages of using EMD are unknown. With the exception of significantly more postoperative complications in the GTR group, there was no evidence of clinically important differences between GTR and EMD. Bone substitutes may be associated with less REC than EMD. Plain language summary:, Enamel matrix derivative (Emdogain®) for periodontal tissue regeneration in intrabony defects. Emdogain might have some advantages over other methods of regenerating the tissue supporting teeth lost by gum disease, such as less postoperative complications, but has not been shown to save more compromised teeth or that patients noticed any aesthetic improvement 1 year after its application. Bacteria in plaque can cause gum disease (periodontitis) that breaks down tissue supporting teeth. Surgical cleaning tries to stop the disease to save loose teeth. Bone grafting, guided tissue regeneration and enamel matrix derivatives (such as Emdogain) aim to regenerate support tissues. Emdogain contains proteins (derived from developing pig teeth) believed to regenerate tooth attachment. The review found that adjunctive application of Emdogain regenerates about 1 mm more tissue than surgical cleaning alone, although it is unclear to which extent such improvement is noticeable since patients did not find any difference in the aesthetic results. Emdogain showed similar clinical results to guided tissue regeneration, but is simpler to use and determines less complications. Bone substitutes may induce less gum retraction than Emdogain. No serious adverse reactions to Emdogain were reported in trials. [source]


Outcome after radical prostatectomy with a pretreatment prostate biopsy Gleason score of ,8

BJU INTERNATIONAL, Issue 6 2003
M. Manoharan
The use of radical prostatectomy to treat patients with high-grade prostate cancer is the subject of much discussion, and the authors from Miami present their considerable experience in this field. They show that patients with a pre-treatment biopsy of Gleason score of ,8 may benefit from radical prostatectomy, assuming a clinical stage of T1,T2, and particularly if their PSA level is <20 ng/mL. Authors from Palermo present data on the long-term outcome of antiandrogen monotherapy in advanced prostate cancer, with the 12-year results of a phase II study. This is a very interesting evaluation, showing that patients with an early objective response have a prolonged progression-free and overall survival. In a large series of superficial bladder tumours, urologists from Tokyo identify a group of patients with tumours of low malignant potential with a high recurrence rate, but a very low invasive property. They suggest that those tumours should be referred to as having a low malignant potential, rather than being called superficial bladder carcinoma. OBJECTIVE To determine the outcome and predictors of recurrence in patients with a pretreatment prostate biopsy Gleason score (GS) of ,,8 and treated with radical prostatectomy (RP). PATIENTS AND METHODS We retrospectively reviewed 1048 consecutive patients who underwent RP by one surgeon (M.S.S.); patients who had a pretreatment biopsy GS of ,,8 were identified. Information was recorded on patient age, initial prostate specific antigen (PSA) level, clinical stage, biopsy GS, pathology GS, extraprostatic extension (EPE), tumour volume, surgical margin status, seminal vesicle invasion (SVI), and lymph node involvement. The results were assessed statistically using the Kaplan-Meier method, univariate log-rank tests and multivariate analysis using Cox's proportional hazards regression. RESULTS In all, 123 patients met the initial selection criteria; 44 were excluded from further analyses (five salvage RP, 23 <,1 year follow-up and 16 adjuvant treatment). Thus 79 patients were included in the uni- and multivariate analyses; 25 (31%) patients had a GS of ,,7 in the RP specimen and 54 (69%) remained at GS ,,8. The mean follow-up was 55 months, the age of the patients 63 years and the mean (sd) initial PSA level 13 (12) ng/mL. The overall biochemical failure rate was 38% (41% if the final GS was , 8 and 32% if it was ,,7). For those with a GS of ,,8 in the RP specimen, 20% (11/54) were organ-confined; two patients (2.5%) in this group developed local recurrence. If the final GS was ,,7, 52% (13/25) were organ-confined. In the univariate analysis, significant risk factors for recurrence were PSA ,,20 ng/mL, EPE, SVI, a positive surgical margin and tumour volume. Cox's proportional regression indicated that a PSA of ,,20 ng/mL (hazard ratio 7.9, 95% confidence interval 2.6,24.2, P < 0.001), the presence of EPE (4.2, 1.6,10.9, P = 0.004) and a positive surgical margin (3.8, 1.5,9.7, P = 0.005) were significant independent predictors in a multivariate analysis. CONCLUSION RP is a reasonable treatment option for patients with a prostate biopsy GS of ,8 and clinical stage T1,2. These patients have a high chance of remaining disease-free if their PSA level is ,,20 ng/mL. Patients with a pretreatment biopsy GS of ,,8 should be counselled about the potential differences between the biopsy and the RP specimen GS. [source]


Long-term effect of repetitive transcranial magnetic stimulation on motor function recovery after acute ischemic stroke

ACTA NEUROLOGICA SCANDINAVICA, Issue 1 2010
E. M. Khedr
Objective,,, Although there is evidence for short term benefits of rTMS in stroke, longer term effects have not been reported. The aim of the study was to evaluate the effect of two different frequencies of rTMS on motor recovery and on cortical excitability up to 1 year post-treatment. Methods,,, Forty-eight patients with acute ischemic stroke were randomly classified into three groups. The first two groups received real rTMS over motor cortex (3 and 10 Hz respectively) of the affected hemisphere and the third group received sham stimulation of the same site, daily for five consecutive days. Disability was assessed before, after fifth sessions, and then after 1, 2, 3 and 12 months. Cortical excitability was assessed for both hemispheres before and after the second and fifth sessions. Results,,, A significant ,rTMS × time' interaction was obtained indicating that real and sham rTMS had different effects on rating scales. This was because real rTMS produced greater improvement than sham that was evident even at one year follow-up. These improvements were associated with changes in cortical excitability over the period of treatment. Conclusion,,, These results confirm that real rTMS over motor cortex can enhance and maintain recovery and may be a useful add on therapy in treatment of acute stroke patients. [source]


First percutaneous transcatheter aortic valve-in-valve implant with three year follow-up

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, Issue 2 2008
Carlos E. Ruiz MD, FSCAI
Abstract Objectives: This study was conducted to report the clinical, hemodynamic, and iconographic outcomes of the longest survivor of the global CoreValve experience. Background: Early results of percutaneous heart valve (PHV) implantation for severe symptomatic aortic stenosis (AS) have been encouraging, with mid term survival up to 2 years; however longer durability term is unknown. Although a PHV has been implanted in a degenerated surgical bioprosthesis, the feasibility of a PHV-in-PHV has not been demonstrated. Methods: A patient with severe refractory heart failure due to severe aortic regurgitation (AR) and moderate AS, underwent CoreValve prosthesis implantation. The PHV was deployed too proximal into the left ventricular outflow tract, resulting in severe AR through the frame struts. Using the first PHV as a landmark, a second CoreValve was then deployed slightly distal to the first, with trivial residual paravalvular leak. Results: The second CoreValve expanded well with proper function. Transvalvular gradient was 8 mmHg. Both coronary ostia were patent. New mild to moderate mitral regurgitation occurred due to impingement of the anterior mitral leaflet by the first PHV. NYHA functional class improved from IV to II, maintained over the past 3 years. Echocardiography at 3 years showed normal functioning CoreValve-in-CoreValve prostheses, without AR or paravalvular leaks. Transvalvular gradient was 10 mmHg. Cardiac CT showed stable valve-in-valve protheses with no migration. Conclusion: The CoreValve prosthesis has maintained proper function up to 3 years, with no structural deterioration or migration. Treating mixed aortic valve disease with predominant AR is feasible. The concept as well as durability of the first PHV-in-PHV has also been demonstrated. © 2008 Wiley-Liss, Inc. [source]


Retinal sensitivity and fixation changes 1 year after triamcinolone acetonide assisted internal limiting membrane peeling for macular hole surgery , a MP-1 microperimetric study

ACTA OPHTHALMOLOGICA, Issue 6 2010
Hakan Ozdemir
Acta Ophthalmol. 2010: 88: e222,e227 Abstract. Purpose:, To evaluate microperimetric changes 1 year after macular hole surgery with triamcinolone acetonide assisted internal limiting membrane (ILM) peeling. Methods:, Twenty-two eyes of 22 patients with stage 3 and 4 idiopathic macular holes of <6 months' duration underwent vitrectomy with triamcinolone acetonide assisted ILM peeling. Best corrected visual acuity (BCVA) (logarithm of the minimum angle of resolution), and central retinal sensitivity were documented before and 1, 3, 6, and 12 months after surgery. Macular sensitivity (mean sensitivity in decibels -dB), and stability and location of fixation (preferred retinal locus) were determined using MP-1 microperimetry (Nidek). The MP-1 microperimetry sensitivity map was overlaid onto infrared images recorded on a Heidelberg scanning laser ophthalmoscope using dedicated MP-1 software to evaluate the fixation location before surgery. Anatomical success was evaluated with optical coherence tomography (OCT). Optical coherence tomography scans were recorded on an OCT 3000 scanner. Results:, Anatomical success was achieved in all 22 eyes. All patients completed 1 year follow-up. No recurrence of macular hole was seen in any patients in the follow-up period. The mean BCVA improved from 0.75 ± 0.2 before surgery to 0.31 ± 0.1 logMAR at the last visit (p < 0.001). Mean sensitivity improved from 3.7 ± 0.6 to 5.3 ± 1.0 dB at the last visit (p < 0.001). Before surgery, the preferred retinal locus was located on the margin of the hole in all, in 18 eyes on its upper part and in four eyes to the side or on its lower part. Preoperatively, 12 eyes were stable and 10 were relatively unstable, but 12 month after surgery, fixation stability had improved, and 20 eyes were stable and two were relatively unstable. Conclusions:, MP-1 microperimetry sensitivity map overlaid onto an infrared image using dedicated MP-1 software can be used successfully to evaluate fixation location in patients with a macular hole before surgery. With microperimetry findings, we can also measure functional macular changes more precisely than using BCVA alone after macular hole surgery. Our results also showed that retinal sensitivity and fixation properties were improved after vitrectomy with triamcinolone acetonide assisted ILM peeling in patients with idiopathic macular hole.

2112: AO imaging of acute macular diseases

ACTA OPHTHALMOLOGICA, Issue 2010
M PAQUES
Purpose To show clinical cases of acute macular diseases and their follow-up by adaptive optics flood imaging. Methods Cases of acute retinal ischemia, of acute macular neuroretinopathy, of photic injury and of poppers-related retinopathy have been observed by a prototypic adaptive optics flood imaging (ImagineEye corporation). Images from follow-up examinations have been registered in order to obtain retinal monitoring at the single photoreceptor level. Iamges were compared to high resolution OCT scans. Results Precise extension and progression/regression of lesions could be documented in all cases. Acute macular neuroretinopathy showed residual cones persisting within an area devoid of any detectable cone. Minute progression and regression of lesions could be documented. Acute ischemia of the inner retina due to central retinal vein occlusion resulted in focal masking of the cone mosaic. The cone mosaic reappeared during follow-up. Photic injury showed no changes over a 1 year follow-up. Images of poppers-related retinopathy showed partial improvement over time. Conclusion Adaptive optics flood imaging allows documentation of the extension and progression of acute maculopathies of various origins. [source]


Montelukast does not prevent reactive airway disease in young children hospitalized for RSV bronchiolitis

ACTA PAEDIATRICA, Issue 11 2009
M Proesmans
Abstract Aim:, To evaluate the long-term effect of montelukast on symptoms of cough and wheeze following RSV bronchiolitis. Methods:, Fifty eight patients (aged , 24 months) hospitalized with a first episode of RSV bronchiolitis were enrolled in this double blind prospective randomized trial comparing montelukast (n = 31) vs placebo (n = 27). Results:, During the 3-month treatment period, there were no statistical significant differences between the two groups for symptom-free days and nights (48.5 [interquartile range 33.0.0,66.0] for montelukast vs 57.0 [29.0,71.0] for placebo p = 0.415) nor disease-free days and nights (44.5 days [26.0,54.0] vs 53.0 [22.3,71.0]; p = 0.266). During the 1 year follow-up, there were 41 exacerbations in the montelukast group vs 54 exacerbations in the placebo group (p = 0.57). Time to first exacerbation was not different. Number of unscheduled visits and need to start inhaled steroids were comparable in the two groups. Conclusion:, Treatment with montelukast after hospital admission for RSV bronchiolitis in children younger than 2 years of age did not reduce symptoms of cough and wheeze. We cannot exclude that a subgroup of children may, however, benefit from this treatment. [source]


Ultrasound of peripheral nerves in acromegaly: changes at 1-year follow-up

CLINICAL ENDOCRINOLOGY, Issue 2 2009
Eugenia Resmini
Summary Context, We have previously demonstrated peripheral nerve enlargement in acromegaly. Objective, The aim of this study was to use ultrasound (US) to assess any changes in the peripheral nerves of patients with acromegaly 1 year after the first evaluation. Patients, We prospectively examined the median and ulnar nerve cross-sectional area (CSA) in 34 non-diabetic, patients with acromegaly (18 females and 16 males; 18,79 years) and 34 age-, sex-, BMI-matched controls, using a 17,5 MHz US probe. Intervention, The median nerve was examined at the mid-forearm (MN-f) and at the carpal tunnel (MN-Ct) levels; the ulnar nerve at mid-forearm (UN-f) and at distal arm (UN-a). Patients were grouped according to the clinical control of the disease: ,improved'; ,always controlled'; ,always uncontrolled'; and ,worsened'. Results, The median nerve at mid-forearm (MN-f), the ulnar nerve at mid-forearm (UN-f) and at distal arm (UN-a) were significantly reduced after 1-year follow-up in all patients (P < 0·001, P < 0·008, P < 0·012, respectively). In the ,improved' group, there was a significant reduction of median nerve CSA examined at mid-forearm (MN-f) (P = 0·02), and distal arm ulnar nerve CSA (UN-a) (P = 0·002). In the other groups no statistically significant differences in ultrasound parameters were recorded. However, UN-a, UN-f, MN-f, MN-ct were still significantly higher in all groups compared with controls (P < 0·001). Conclusion, These data demonstrate that median and ulnar nerves CSA are reduced after 1 year follow-up, in line with the reduction of GH/IGF-I levels. However, as the control of the disease incompletely reverts nerve enlargement, this phenomenon could be only partially reversible. [source]


Clinical outcome of submerged vs. non-submerged implants placed in fresh extraction sockets

CLINICAL ORAL IMPLANTS RESEARCH, Issue 12 2009
Luca Cordaro
Abstract Aim: The aim of this study was to compare the clinical outcome of submerged vs. non-submerged tapered implants placed into fresh extraction sockets. Materials and methods: A prospective, controlled, multicenter, randomized, clinical trial has been performed in two centers in Rome and Torino (Italy). Thirty healthy patients were recruited according to the following inclusion criteria: need for an immediate post extraction implant, ages between 18 and 70, horizontal defect depth <2 mm, smokers <10 cigarettes/day and absence of any circumstance or condition that could represent contraindications to implant surgery. The patients were randomly allocated to submerged or non-submerged treatment groups immediately after flap elevation and tooth extraction. Submerged implants were exposed 8 weeks after the first surgery; all implants were loaded with provisional restorations 12 weeks after the first surgery and with definitive restoration 12 weeks thereafter. Clinical and radiographic parameters were evaluated at baseline, at implant loading and at the 1-year follow-up visit. Results: The results showed statistically significant differences between the two groups in the mean value of keratinized tissue (KT) height after surgery that was significantly reduced for submerged implants when compared with transmucosal implants (mean reduction of KT at year follow-up: T group 0.2 mm, S group 1.3 mm; P=0.007). Conclusion: Similar outcomes were found for submerged and non-submerged implants placed in fresh extraction sockets with a horizontal peri-implant defect smaller than 2 mm, except for a reduction of KT in the submerged group. Either with a submerged or a non-submerged procedure, 1 mm of mean soft tissue recession is seen after 1 year when compared with the pre-extraction situation. [source]
