Selected AbstractsCan objective parameters derived from videofluoroscopic assessment of post-laryngectomy valved speech replace current subjective measures?CLINICAL OTOLARYNGOLOGY, Issue 6 2006An e-tool-based analysis Objectives:, The primary purpose of this study was to assess the pharyngoesophageal segment in total laryngectomy patients using a videofluoroscopy e-tool. Study design:, Cross-sectional study. Setting:,, Head and Neck Oncology Unit, Tertiary Referral Centre. Patients:, Forty-two patients following total laryngectomy. Intervention:, Videofluoroscopy using an e-tool (JRuler). Main outcome measures:, Subjective and objective videofluoroscopy parameters correlated with the GRBAS scale and treatment variables. Results:, Of 32 men and 10 women, mean age 63.5 years (10.8) the majority (64.3%) had a reasonable voice (good = 11 and poor = 4 patients). Comparing subjective and objective parameters, significant correlations were only seen with a smaller minimal neoglottic distance at phonation with no regurgitation of barium at phonation (P = 0.05) and a type 1 shape of neoglottis at phonation (P = 0.02). There were also significant correlations between smaller maximum sub-neoglottic distance at phonation and type 1 shape of neoglottis (P = 0.02), smaller maximum sub-neoglottic distance at rest and absence of stasis of barium at phonation (P = 0.05) and the length of neoglottis at phonation and type 1 shape of neoglottis (P = 0.01). For perceptual evaluation, significant correlation was seen only between G1 voice and a smaller minimal neoglottic distance at phonation (P = 0.03) amongst the subjective and objective parameters. There were no correlations between visual parameters and the clinical parameters. Conclusions:, Our observations suggest that this interesting concept has limitations. While objective and quantifiable data can be obtained using videofluoroscopy in laryngectomees, only a few correlate with each other and with voice quality.

Appropriate antenatal corticosteroid use in women at risk for preterm birth before 34 weeks of gestation. BJOG 2010;117:963,967. Objective, To determine the utilisation of antenatal corticosteroid administration in women presenting at risk of preterm birth (PTB) in a centre where tocolytics are not prescribed. Design, A prospective cohort study. Setting, Tertiary referral centre, Dublin, Ireland. Population, Four hundred and fourteen consecutive women presenting at risk of PTB. Methods, Clinical details were collated prospectively on all booked patients who presented at risk of PTB (i.e. at <34 weeks of gestation) during 2008. Main outcome measure, Rate of administration of antenatal corticosteroids in PTB. Results, Of 8985 deliveries, 414 women (5%) presented at <34 weeks of gestation with a clinical potential for PTB, of whom 277 (67%) received antenatal corticosteroids. Amongst women delivering at <34 weeks of gestation, 93% (80/86) received any corticosteroids and 76% (65/86) received a complete course. The ratio of women given a complete course of corticosteroids to the number who actually delivered before 34 weeks of gestation was 4:1 overall. Analysis by indication for PTB revealed this ratio to be 15:1 in suspected preterm labour (PTL), 8:1 in antepartum haemorrhage (APH), and 2:1 in both preterm prelabour rupture of membranes (PPROM) and medically indicated PTB (MIPTB). Seven of ten multiparae (70%) who delivered prematurely during the study period following PTL had a history of previous PTL before 34 weeks of gestation. Conclusion, The ratio of maternal antenatal corticosteroid administration for potential versus actual PTB at <34 weeks of gestation was high in categories such as PTL and substantial APH, whereas selection in PPROM and MIPTB approached 100%. There should be a low threshold for single course therapy for women with prior PTL before 34 weeks of gestation. [source] Different profiles of circulating angiogenic factors and adipocytokines between early- and late-onset pre-eclampsiaBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 3 2010H Masuyama Please cite this paper as: Masuyama H, Segawa T, Sumida Y, Masumoto A, Inoue S, Akahori Y, Hiramatsu Y. Different profiles of circulating angiogenic factors and adipocytokines between early- and late-onset pre-eclampsia. BJOG 2010;117:314,320. Objective, Circulating angiogenic factors have been shown to be important in the pathophysiology of pre-eclampsia. Blood levels of adipocytokines differ in pre-eclampsia relative to controls and may also play an important role in disease pathogenesis. Differences in the circulating levels of these molecules were compared between matched normotensive controls and women with pre-eclampsia with onset before or at/after 32 weeks, and according to whether the women were of normal weight (18.5 < body mass index < 25) or overweight. Design, A cross-sectional study of 110 pregnant Japanese women who visited the Department of Obstetrics and Gynecology, Okayama University Hospital, Okayama, Japan. Setting, Tertiary referral centre serving 2000 births. Methods, Serum concentrations of soluble fms-like tyrosine kinase 1 (sFlt-1), placental growth factor (PlGF), soluble endoglin (sEng), adiponectin and leptin were measured in women with pre-eclampsia and in normotensive controls matched for age, gestational week, parity and body mass index. Main outcome measures, Serum levels of sFlt-1, PlGF, the sFlt-1/PlGF ratio, sEng, adiponectin and leptin. Results, The sFlt-1/PlGF ratio in early-onset pre-eclampsia was significantly higher than that in late-onset pre-eclampsia (112.0 ± 30.2 versus 45.4 ± 43.8, P = 0.037). There was a significant elevation of leptin in both subtypes relative to controls (early: 58.6 ± 18.3 ng/ml versus 26.0 ± 6.7 ng/ml, P = 0.001; late: 39.5 ± 9.2 ng/ml versus 22.0 ± 4.3 ng/ml, P = 0.005), but adiponectin was increased only in late-onset pre-eclampsia (36.5 ± 13.4 ,g/ml versus 12.0 ± 4.3 ,g/ml, P = 0.003). Significant differences in angiogenic factors and adiponectin were found between normal and overweight women only in late-onset pre-eclampsia. Conclusions, These data suggest that there are different profiles of angiogenic factors and adipocytokines between women who develop early- and late-onset pre-eclampsia. [source] Expectant management of early onset, severe pre-eclampsia: perinatal outcomeBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 10 2000D. R. Hall Consultant Objective To evaluate the perinatal outcome of expectant management of early onset, severe pre-eclampsia. Design Prospective case series extending over a five-year period. Setting Tertiary referral centre. Population All women (n= 340) presenting with early onset, severe pre-eclampsia, where both mother and the fetus were otherwise stable. Methods Frequent clinical and biochemical monitoring of maternal status with careful blood pressure control. Fetal surveillance included six-hourly heart rate monitoring, weekly Doppler and ultrasound evaluation of the fetus every two weeks. All examinations were carried out in a high care obstetric ward. Main outcome measures Prolongation of gestation, perinatal mortality rate, neonatal survival and major complications. Results A mean of 11 days were gained by expectant management. The perinatal mortality rate was 24/1000 (, 1000 g/7 days) with a neonatal survival rate of 94%. Multivariate analysis showed only gestational age at delivery to be significantly associated with neonatal outcome. Chief contributors to neonatal mortality and morbidity were pulmonary complications and sepsis. Three pregnancies (0.8%) were terminated prior to viability and only two (0.5%) intrauterine deaths occurred, both due to placental abruption. Most women (81.5%) were delivered by caesarean section with fetal distress the most common reason for delivery. Neonatal intensive care was necessary in 40.7% of cases, with these babies staying a median of six days in intensive care. Conclusion Expectant management of early onset, severe pre-eclampsia and careful neonatal care led to high perinatal and neonatal survival rates. It also allowed the judicious use of neonatal intensive care facilities. Neonatal sepsis remains a cause for concern. [source] Preoperative blood sugar and C-reactive protein associated with persistent discharge after incision and drainage for patients with deep neck abscessesCLINICAL OTOLARYNGOLOGY, Issue 4 2009S.-A. Liu Objectives:, The aim of this study was to investigate whether preoperative C-reactive protein (CRP) and blood sugar correlated with persistent discharge after incision and drainage for patients with deep neck abscesses. Study design:, Retrospective data analysis. Setting:, Tertiary referral centre. Participants:, A total of 204 patients who underwent operation for deep neck abscess. Main outcome measures:, Persistent discharge after operation. Results:, One hundred seventy patients were included for final analyses. Most of the patients were male (n = 115; 68%) and the average age was 54 years. Using logistic regression analyses, age >55 years [odds ratio (OR): 3.053; P = 0.002], preoperative CRP >15 mg/dL (OR: 2.174; P = 0.027), and preoperative blood sugar >8.3 mmol/L (OR: 3.280; P = 0.001) were independent factors correlated with persistent discharge. Conclusions:, Older age, elevated preoperative CRP level and blood sugar had a statistically significant association with persistent discharge after operation in deep neck abscesses patients. [source] Clinical aspects on neonatal cholestasis based on observations at a Swedish tertiary referral centreACTA PAEDIATRICA, Issue 2 2001B Fischler The aim of the study was to investigate the clinical aspects of neonatal cholestasis. The medical records of 85 cholestatic infants were retrospectively reviewed. A majority of the patients were referred from other parts of the country. The most common diagnoses were extrahepatic biliary atresia (n= 30 patients), ,1 -antitrypsin deficiency (n=11) and progressive familial intrahepatic cholestasis (n= 11). On presentation, the biliary atresia group had higher mean serum values of bilirubin, G-GT and cholesterol than the patients with intrahepatic cholestasis, with no significant differences noticed for any other biochemical parameter. A lack of excretion on hepatobiliary scintigraphy was noticed in all investigated patients with biliary atresia, but also in 9 of 34 patients with intrahepatic neonatal cholestasis. There was no statistical correlation between the age at portoenterostomy and the outcome in patients with biliary atresia. However, both the detection of a partial flow on perioperative cholangiogram and the establishment of a non-icteric phase within 6 mo after the portoenterostomy correlated to a good outcome. Eight of 11 patients with progressive familial intrahepatic cholestasis were treated with a biliary diversion procedure, five of eight experienced a sustained cholestatic remission. Conclusions: Progressive familial intrahepatic cholestasis may be a more common cause of neonatal cholestasis in Sweden than reported elsewhere and that the experience with biliary diversion is positive. While early referral in patients with extrahepatic biliary atresia remains important, a portoenterostomy should be attempted also in patients referred after 3 mo of age. [source] Investigating moderate to severe paediatric trauma in the Auckland regionEMERGENCY MEDICINE AUSTRALASIA, Issue 2 2010Louise Couch Abstract Objective: To investigate differences between paediatric patients with moderate to severe trauma admitted from two paediatric ED, with respect to: demographics, patterns of presentation, mechanism of injury, injury severity scores (ISS), interventions and outcome. Method: Retrospective cohort study. Moderate to severe trauma was defined as ISS >9. Paediatric patients admitted to hospital via Starship Children's Emergency or KidzFirst ED, with trauma from 1 May 2003 to 30 April 2004, with ISS >9 were identified using multiple databases. The charts were reviewed and data collected included: demographics, hospital of first presentation, diagnoses, ISS, Paediatric trauma score (PTS), Glasgow coma score (GCS), ventilator hours, length of admission, survival and discharge destination. Descriptive statistics with 95% confidence intervals, Mann,Whitney U -test, ,2 -test and Fisher's exact test were used as appropriate. Results: A total of 393 children with moderate to severe trauma were identified using initial search strategies. Of these, 82 children met the inclusion and exclusion criteria for the study; 42 children were admitted via KidzFirst ED and 40 via Starship Children's ED. There was no statistically significant difference in ISS (P= 0.86), PTS (P= 0.11), GCS (P= 0.62), hours on a ventilator (P= 0.28) and length of stay (P= 0.87) between children admitted from Starship or KidzFirst ED. Conclusion: This study suggests that there are no differences in the numbers or severity of paediatric trauma patients admitted from the Starship and KidzFirst ED. This indicates triage is to the closest ED despite having a tertiary referral centre for paediatric trauma available in Auckland City. [source] Prognostic Factors Affecting Long-Term Retention of Topiramate in Patients with Chronic EpilepsyEPILEPSIA, Issue 3 2000S. D. Lhatoo Summary: Purpose: To determine the long-term retention rate of topiramate (TPM) therapy in patients with chronic epilepsy and to identify the relevant prognostic factors that influence retention. Methods: All patients with chronic epilepsy (n = 393) prescribed TPM between October 1, 1995, and December 31, 1998, at a tertiary referral centre for epilepsy were analysed. The retention rate for TPM was calculated by using Kaplan-Meier survival analysis, and the prognostic factors influencing retention were analysed by using Cox regression. Results: Of patients prescribed TPM, 30% continued taking the drug beyond 3 years. Discontinuation was mainly due to adverse events and lack of efficacy. Use of more than one new concurrent antiepileptic drug (AED) and lower maximal daily doses were more likely to result in treatment discontinuation due to adverse events. Older age at onset of epilepsy, a history of having previously taken more than one new AED [lamotrigine (LTG), gabapentin (GBP), or vigabatrin (VGB)], and lower maximal daily doses were more likely to lead to discontinuation due to lack of efficacy. Conclusions: A third of patients with chronic epilepsy started on TPM therapy will continue on treatment for >3 years. Absence of learning disabilities, late age at onset of seizures, previous use of more than one new AED, two or more concurrent AED use, and low maximal daily doses of TPM are more likely to result in discontinuation of medication. These factors should be taken into account when considering the use of TPM for the treatment of chronic epilepsy. [source] Low-Dose Topiramate Versus Lamotrigine in Migraine Prophylaxis (The Lotolamp Study)HEADACHE, Issue 3 2007Praveen Gupta MD Objective.,To assess the efficacy and safety of topiramate and lamotrigine for prophylaxis in patients with frequent migraine as compared to each other and to placebo. Methods.,Sixty patients with frequent migraine (more than 4 attacks per month) from the headache clinic at a tertiary referral centre in India were randomized to receive 50 mg topiramate/lamotrigine or matching placebo for 1 month each in 2 divided doses in 4 phases in a crossover manner with a washout period of 7 days in between. Primary efficacy measure was responder rate (50% decrease in mean migraine frequency/intensity). Secondary efficacy measures included reduction in mean monthly frequency, intensity, duration, rescue medication use, migraine associated symptoms, and adverse events. Statistical analysis.,Analysis was on intention to treat basis. Data were analyzed as correlated data. Generalized estimation equation was used to compute overall mean standard deviation and 95% confidence intervals for each of the outcome variables. Bonferroni's correction done for multiple comparisons. P value of <.017 was taken as significant. Results.,Fifty-seven patients comprised the intent-to-treat population. Four patients withdrew from the study at various phases, none because of the side effects. Responder rate for frequency was significantly higher for topiramate versus placebo (63% vs 30%, P < .001), and versus lamotrigine (63% vs 46 %, P= .02). For intensity of headache also a responder rate of topiramate versus placebo (50% vs 10%, P < .001), and versus lamotrigine (50% vs 41%, P= .01) was observed. Topiramate showed statistically significant benefits (P < .017) in most of the secondary efficacy measures while lamotrigine was beneficial for reduction in headache frequency, and migraine associated symptoms. Adverse events were similar. Conclusion.,Low-dose topiramate is efficacious in migraine prophylaxis as compared to both placebo and lamotrigine. Lamotrigine in low doses might be beneficial for headache frequency; however, longer trials are required to establish its efficacy on the intensity and frequency of migraine. [source] Occupational risks for male fertility: an analysis of patients attending a tertiary referral centreINTERNATIONAL JOURNAL OF ANDROLOGY, Issue 6 2001Sebastian Kenkel The impact of environment and occupation on male fertility is still under debate. We investigated whether certain occupations may be over- or under-represented among men attending our infertility clinic in relation to the entire population of the area. Diagnoses and semen parameters of 2054 infertile men from the district of Münster were analysed retrospectively. The patients were categorized into 29 occupational groups. The relative size of each group was compared with that of the entire population in the district of Münster. Farmers were over-represented compared with the general population. Farmers and painters/varnishers showed a significantly higher proportion of reduced sperm counts [odds ratios (OR): 2.13 and 2.17, 95% confidence intervals: 1.18,3.88 and 1.02,4.65] and severely reduced sperm concentrations compared with the entire group of infertile men; in addition, significantly more farmers presented with a history of maldescended testes than other occupational groups (OR: 2.76 and 2.84; CI: 1.12,6.75 and 1.27,6.34). Metal workers/welders formed significantly higher proportions of patients with reduced sperm motility (OR: 5.99; CI: 1.38,26.00). The relatively poor semen parameters of the painters/varnishers could be caused by exposure to toxins. This may also apply to the farmers (fertilizers, herbicides); however, the elevated rate of maldescended testes suggests an effect of exposure during prenatal development or a genetic cause. The findings for metal workers/welders may be because of heat or toxins at the workplace. The study demonstrates that certain occupations are preferentially associated with male infertility. [source] Low-grade fever: how to distinguish organic from non-organic formsINTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 3 2010M. Affronti Summary Background and aim:, Low-grade fever (LGF) is defined as a body temperature between 37.5 and 38.3 °C, which is below the classical value reported for fever of unknown origin (FUO). We attempted to characterise its epidemiology, aetiology and clinical aspects to improve the methodological approach to diagnosis. Design and Methods:, We reviewed and evaluated a survey of patients with LGF, followed as outpatients of our Department, a tertiary referral centre from 1997 to 2008. The same classifications were applied for classical FUO, and in the patients diagnosed with LGF, we also investigated for habitual hyperthermia (HH). Results:, Seventy-three patients were selected and divided into two groups: group A included 32 patients classified with organic fever and group B included 41 patients with HH. Aetiology of organic LGF was: infectious disease 59%; neoplasm 3.1%; inflammatory non-infectious disease 6.2%; miscellaneous 18.7%; undiagnosed 12.5%. Mean age was significantly higher in the organic fever than in the HH group (p < 0.02). Splenomegaly and loss of weight were significantly associated with organic fever (p < 0.05), while dizziness and general malaise were associated with HH. Lack of any pathological signs at physical examination was significantly more frequent in HH (p < 0.0001). Among the biochemical tests, white blood cells and C-reactive protein were more frequently above normal limits in group A than in group B (p < 0.05). Conclusions:, In our experience, LGF requires the same methodological diagnostic approach as FUO, because there is no relationship between body temperature values and the severity of the underlying diseases, and the aetiological spectrum is also the same. [source] The prevalence of vitamin D abnormalities in South Asians with type 2 diabetes mellitus in the UKINTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 3 2010A. A. Tahrani Summary Background:, The high prevalence of both hypovitaminosis D and type 2 diabetes (T2DM) in the Asian community is well recognised, but the impact of diabetes on vitamin D status and vice versa, has not been well reported. Aims:, To determine the prevalence of hypovitaminosis D in Asian patients with T2DM and its impact on glycaemic control. Methods:, A cross-sectional study was conducted in a tertiary referral centre in the UK. Two hundred and ten Asian patients aged more than 40 years were included (170 with and 40 without T2DM). Each had a standard bone profile (serum calcium, phosphate and alkaline phosphatase), serum parathyroid hormone and 25-hydroxycholecalciferol. Results:, The prevalence of low serum 25-hydroxyvitamin D (< 50 nmol/l) was high in the group as a whole (> 80%) and more common in diabetics compared with controls (83% vs. 70%; p = 0.07). This was particularly so in men (82.5% vs. 57.9%; p = 0.02). HbA1c was higher in women with vitamin D deficiency (< 12.5 nmol/l) (8.11 ± 1.11% vs. 7.33 ± 1.32%, p = 0.046). In logistic regression analysis, T2DM was an independent predictor of hypovitaminosis D. In linear regression analysis, vitamin D deficiency was independently related to HbA1c in women with T2DM. Conclusions:, Hypovitaminosis D remains a major public health issue in the Asian population and is exaggerated in patients with T2DM. The fact that vitamin D deficient women had higher HbA1c levels raises the possibility that vitamin D replacement may improve glycaemic control. [source] Prostate cancer in London: is the triadic clinical encounter the standard?INTERNATIONAL JOURNAL OF UROLOGICAL NURSING, Issue 2 2008Amanda Euesden Hughes Abstract It has been reported that men with prostate cancer in London were less satisfied with the service they received than patients with other cancers. Studies from the USA have looked at the experience of the prostate cancer couple. It has been established that the cancer couple have information needs and that when a clinical encounter is triadic in nature, these needs are more likely to be met and information is more likely to be retained. The aim of this study was to examine the clinic attendance patterns of men in London with prostate cancer (n = 200). A comparison group of women in London with breast cancer was identified (n = 200). Direct observation of the groups was performed, accompanied/unaccompanied (triadic/dyadic) attendance was recorded and demographic data were extracted from the clinical notes. Forty-one percent (81) of the women experienced their clinical encounter as a triad compared with 24% (48) of the prostate group who experienced their clinical encounter as a dyad between themselves and their health care provider (p < 0.05). In the first year of diagnosis, men with prostate cancer were more likely to experience a triadic encounter, but this was more evenly distributed throughout the cancer journey for women with breast cancer. There did not appear to be a correlation with marriage and triadic encounters for either group. Men with prostate cancer in this tertiary referral centre in London are less likely to experience a triadic clinical encounter than women with breast cancer. Further work is needed to establish a relationship between unmet informational needs of the prostate cancer couple and the high level of dissatisfaction in the prostate cancer population in London, but the nature of the dyadic encounter may play a part in this. [source] Methotrexate in paediatric ulcerative colitis: a retrospective survey at a single tertiary referral centreALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 8 2010M. Aloi Aliment Pharmacol Ther 2010; 32: 1017,1022 Summary Background, Patients with ulcerative colitis often receive thiopurines as immunomodulators (IMs) to maintain remission and avoid corticosteroids. If unresponsive or intolerant to these agents, patients are treated with methotrexate, an antimetabolite never assessed in paediatric ulcerative colitis. Aim, To describe the experience with methotrexate in children with ulcerative colitis. Methods, Thirty-two patients (median age 13.9 years) received methotrexate. Pediatric Ulcerative Colitis Activity Index (PUCAI) and use of corticosteroids were the main outcomes evaluated at baseline and at 3, 6 and 12 months. Results, Indications to methotrexate were azathioprine unresponsiveness in 18 patients, azathioprine intolerance/toxicity in 10 and spondyloarthropathy in four. Response or remission was achieved in 72%, 63% and 50% of patients at 3, 6 and 12 months respectively. Mean PUCAI were 49.5 ± 23.3 at baseline and 32.9 ± 21.9, 29.5 ± 21.8 and 29.4 ± 19.9 at 3, 6 and 12 months respectively (P: 0.03). At the beginning of methotrexate, 16 patients (50%) received corticosteroids that were discontinued in 13 of them (81%) by 6 months. At the end of the study, 11 patients (33%) needed short courses of corticosteroids for disease relapse. Conclusions, Methotrexate may be useful in treating children with ulcerative colitis, although large, controlled trials are warranted to define better its effectiveness. [source] Use of inferior vena cava filters in a tertiary referral centre in AustraliaANZ JOURNAL OF SURGERY, Issue 5 2010Alok Tiwari Abstract Introduction:, To investigate the use of inferior vena cava (IVC) filters in a tertiary referral centre, looking at indication, types of filters and, with temporary/optional filters, removal rates. Methods:, Data was collected from a prospective database of all IVC filters inserted from January 2003 to January 2007. Patients' records and radiological imaging were all reviewed. Results:, 66 patients (40 males) had IVC filters inserted during the study period. The median age of the male patients was 57.5 (21,79) years, and females 56 (24,81). There were 49 (74.2%) temporary/optional filters and 17 (25.8%) permanent filters. The most common indication for filter was a contraindication to anticoagulation for both permanent (64.7%) and temporary/optional filters (77.6%). In the temporary/optional filter group, 38 of 49 (77.6%) patients had documented venous thromboembolism, while in the permanent filter group, this was 14 of 17 (82.4%). Of the optional filters, 22 of 49 (45.8%) have been removed. Conclusion:, More than half (54.2%) of temporary/optional filters were not removed and with potential for long-term complications. A protocol has now being instituted for vascular surgeons to authorize the insertion of filters and to then be responsible for ensuring their removal. [source] MINIMALLY INVASIVE PARATHYROIDECTOMY USING SURGEON-PERFORMED ULTRASOUND AND SESTAMIBIANZ JOURNAL OF SURGERY, Issue 9 2007Subhita Prasannan Background: Surgeon-performed ultrasound (SPU) and 99mTc-sestamibi (SM) scanning can be used alone or in combination in patients with primary hyperparathyroidism to select cases suitable for minimally invasive parathyroidectomy (MIP). The aim of the study was to evaluate SPU and SM and to determine the reliability they provide the surgeon in planning and carrying out MIP. Methods: The study was a prospective analysis of 130 patients with primary hyperparathyroidism who had preoperative localization with SPU and SM at a tertiary referral centre between 2003 and 2006. All ultrasound scans were carried out by one surgeon, followed by correlative sestamibi scan and a further ,on operating table' ultrasound to reassess the lesion and mark the operative site. Selection criteria for MIP were a positive SPU and SM, although a positive SPU or SM allowed the surgeon to focus on the nominated side. SPU and SM localizations were correlated to the operative findings. Results: One hundred and thirty patients underwent both SPU and SM. There were 97 women and 33 men, with a mean age of 59 years. SPU alone identified the abnormal parathyroid in 103 cases (sensitivity 82%; positive predictive value 96.3%). SM alone identified the abnormal gland in 102 cases (sensitivity 79%; positive predictive value 99%). In 88 patients, the SPU and SM were concordant, and 94% had successful MIP. SPU and SM were both negative in 13 patients, and all these patients had bilateral neck exploration. Conclusion: SPU in the hands of an experienced surgeon in association with sestamibi is a reliable tool for the preoperative localization of parathyroid adenomas and facilitates a minimally invasive procedure. [source] Outpatient hysteroscopy: Factors influencing post-procedure acceptability in patients attending a tertiary referral centreAUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 6 2009Kate MCILWAINE Background:, Ambulatory hysteroscopy is a safe, reliable and cost-effective alternative to hysteroscopy under a general anaesthetic for the diagnosis of abnormal uterine bleeding. Aim:, The objective of this study was to assess which factors influenced patients' willingness to attend for future outpatient hysteroscopy. The outpatient hysteroscopy service commenced at the Mercy Hospital for Women in 2000. It provides women with the opportunity to have the cause of abnormal uterine bleeding diagnosed in an outpatient setting. Methods:, A prospective audit was conducted of 283 women attending for outpatient hysteroscopy at the Mercy Hospital for Women over a period of almost five years (May 2003 through February 2008). Results:, Of the women audited, 88.7% stated that they would accept the procedure in future, whilst 11.3% would not. There was a significant difference between the two groups with respect to their median visual analogue pain scale (VAS) pain scores during the procedure (3.00 versus 6.50 P < 0.0001) with the higher score in the group who would not re-attend for the procedure. There was also a significant difference between the two groups with respect to the change in median VAS score from pain anticipated to pain experienced (0.00 versus 3.50 P = 0.0001). The rate of unsuccessful procedures was significantly higher (40.6% versus 0.8%P < 0.05) in future non-attendees as well as a higher rate of clinical vasovagal episodes (25% versus 5.2%P = 0.01) in women who stated that they would not re-attend for the procedure. Preprocedure analgesia and type of anaesthetic administered during the procedure did not seem to influence whether women would attend for outpatient hysteroscopy in future. Conclusions:, The acceptability rate for women attending for outpatient hysteroscopy during the audit period was 88.7%. Pain was a significant determinant of procedure acceptability; however, the acceptability rate was not influenced by analgesia or type of anaesthetic administered. [source] In vivo magnetic resonance spectroscopy of gynaecological tumours at 3.0 TeslaBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 2 2009SJ Booth Background, Magnetic resonance spectroscopy (MRS) uses the same hardware as MR imaging and allows us to analyse the biochemistry of tissues in vivo. Published data for gynaecological lesions are limited and are largely based on MRS carried out at the lower magnetic field strength of 1.5 Tesla (T). Objective, The purpose of this study was to determine whether in vivo proton MRS could be performed at the higher magnetic field strength of 3 T to characterise the spectra of a variety of benign and malignant gynaecological lesions. Design, Prospective, non-randomised study. Setting, MRI department within a tertiary referral centre for gynaecological cancers. Sample, All women with a pelvic mass under going 3T MRI. Methods, We carried out MRS on nonrandomised women undergoing routine 3 T MRI within our MRI department during investigation for gynaecological lesions from February 2006 to April 2008. Only those women for whom histopathological data were available were included. Main outcome measures, The presence of choline detected by in vivo 3T MRS. Results, Eighty-seven women underwent MRS, 57 of whom had newly diagnosed neoplasms. MRS data for 39 of these new women (18 were excluded because of technical errors or missing data) were used to detect the presence of choline, an indicator of basement membrane turnover. Overall, choline was present in 13 of the 14 ovarian cancers, 8 of the 11 cervical tumours and all 4 of the uterine cancers. There was no statistical significant difference between choline levels in various lesion types (P= 0.735) or between benign and malignant disease (P= 0.550). Conclusions,In vivo MRS can be performed at 3 T to provide biochemical information on pelvic lesions. The way in which this information can be utilised is less clear but may be incorporated into monitoring tissue response in cancer treatments. [source] Total laparoscopic hysterectomy as a primary surgical treatment for endometrial cancer in morbidly obese womenBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 1 2005C.K.H. Yu To evaluate the feasibility of total laparoscopic hysterectomy as the primary treatment for endometrial cancer in morbidly obese women, an audit was carried out during an 18-month period in a tertiary referral centre for gynaecological oncology. Four women who had laparoscopic surgery were compared with a similar cohort who had open surgery. The mean operating time was equivalent, without evidence of excess morbidity with the laparoscopic approach. However, inpatient stay was longer with open versus laparoscopic surgery (11.5 vs 4 days). Laparoscopic surgery is safe to use in morbidly obese women with endometrial cancer. [source] The Shared Equal Access Regional Cancer Hospital (SEARCH) nomogram for risk stratification in intermediate risk group of men with prostate cancer: validation in the Duke Prostate Center databaseBJU INTERNATIONAL, Issue 2 2010Jayakrishnan Jayachandran Study Type , Prognosis (cohort) Level of Evidence 2a OBJECTIVES To validate the Shared Equal Access Regional Cancer Hospital (SEARCH) nomogram to better risk stratify men with intermediate-risk pathology after prostatectomy (positive surgical margins, PSM, and/or extracapsular disease, ECE, without seminal vesicle or lymph node involvement) in a tertiary referral centre (the Duke Prostate Center, DPC). PATIENTS AND METHODS We retrospectively analysed 485 men in the DPC cohort with PSM and/or ECE but without seminal vesicle or lymph node involvement. The predicted risk of biochemical progression-free probability at 1, 3 and 5 years was estimated by the SEARCH and updated Kattan postoperative nomograms. Calibration plots were generated and accuracy assessed with the concordance index. RESULTS The SEARCH nomogram appeared to be well calibrated, with the highest-risk quartile having a predicted <60% progression-free probability at 5 years, vs >80% for the lowest risk. In comparison, overall external calibration appeared to be similar for the updated Kattan nomogram, although there was less separation between the highest- and lowest-risk quartiles. The SEARCH model had an overall predictive accuracy of 0.65, which compared favourably with the updated Kattan nomogram (0.57). CONCLUSION In an external dataset, the SEARCH nomogram to predict progression-free probability for men at intermediate risk after prostatectomy was well calibrated and performed better than the updated postoperative Kattan nomogram. [source] Hand dermatitis and lymphoedemaBRITISH JOURNAL OF DERMATOLOGY, Issue 1 2009V.J. Pearce Summary Hand dermatitis is common, with lymphoedema of the hand and forearm a rare complication. The mechanism of lymphoedema in such cases is poorly understood, hence management can be challenging. To investigate the underlying mechanism of lymphoedema associated with hand dermatitis and outline recommendations for management, we identified all patients with lymphoedema associated with hand dermatitis referred to our lymphoedema service, a tertiary referral centre. Treatment outcome was assessed by telephone interview and through correspondence with primary physicians and therapists. In total, nine patients, six with bilateral and three with unilateral lymphoedema associated with hand dermatitis, attended our service over a 4-year period. Most had long-standing bilateral pompholyx eczema. Three patients reported no signs of infection prior to the onset of swelling. All patients had recurrent episodes of infection after the onset of swelling. Lymphoscintigraphy, when used, revealed a failure of small initial lymphatics of the hand to absorb and drain lymph to regional nodes. Prophylactic antibiotics together with aggressive management of the dermatitis, often with systemic therapy, were required to reduce swelling. Possible mechanisms for lymphoedema associated with hand dermatitis include obliterative lymphangitis from infection, an inflammatory effect of the dermatitis on local lymphatics or a constitutive weakness of lymph drainage exposed to chronic inflammation, or any combination of the three. Treatment is only successful once both infection and inflammation from the dermatitis are controlled. [source] Extensive venous/lymphatic malformations causing life-threatening haematological complicationsBRITISH JOURNAL OF DERMATOLOGY, Issue 3 2007J. Mazereeuw-Hautier Summary Background, Large venous/lymphatic slow-flow malformations (SFM) can be associated with a coagulopathy resulting in thrombosis and haemorrhage. Such potentially life-threatening complications of SFM have been reported only rarely. Objectives, To better define the clinical characteristics of haematological complications associated with SFM, to highlight the importance of recognition and to discuss the management of these difficult-to-treat patients. Patients and methods, A cohort of six children who presented with massive SFM associated with serious haematological complications was seen between January 1980 and June 2005 in the Department of Paediatric Dermatology, Great Ormond Street Hospital for Children, London, U.K. (tertiary referral centre for vascular anomalies). Clinical and haematological characteristics were recorded. Results, Patients were aged 1,20 years. All suffered with recurrent episodes of pain, localized skin necrosis and bleeding. All had intravascular coagulopathy and life-threatening complications. These included brain haemorrhage, massive bleeding from the uterus and colon, large and extensive thromboses of the deep vessels in the abdomen and pelvis and severe haemoptysis. One patient died suddenly at the age of 20 years from pulmonary thromboembolism and thrombosis within the deep vessels of the vascular malformation. The youngest patient underwent a leg amputation to remove the huge vascular malformation due to the major risk of complications and lack of limb function. Three of the patients underwent anticoagulation treatment and showed improvement in their coagulopathy. Conclusions, It is essential that patients with extensive SFM have their coagulation screened regularly to detect intravascular coagulopathy. This may progress to disseminated vascular coagulopathy and a serious risk of thrombosis and haemorrhage. Such patients require early anticoagulation in an attempt to prevent these secondary complications. [source] An 11-year experience of enterocutaneous fistula,BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 12 2004P. Hollington Background: Enterocutaneous fistula has traditionally been associated with substantial morbidity and mortality, related to fluid, electrolyte and metabolic disturbance, sepsis and malnutrition. Methods: A retrospective review of enterocutaneous fistula in 277 consecutive patients treated over an 11-year period in a major tertiary referral centre was undertaken to evaluate current management practice and outcome. Results: Most fistulas occurred secondary to abdominal surgery, and a high proportion (52·7 per cent) occurred in association with inflammatory bowel disease. A low rate of spontaneous healing was observed (19·9 per cent). The healing rate after definitive fistula surgery was 82·0 per cent, although more than one attempt was required to achieve surgical closure in some patients. Definitive fistula resection resulted in a mortality rate of 3·0 per cent. In addition, one patient died after laparotomy for intra-abdominal sepsis and an additional 24 patients died from complications of fistulation, giving an overall fistula-related mortality rate of 10·8 per cent. Conclusion: Early recognition and control of sepsis, management of fluid and electrolyte imbalances, meticulous wound care and nutritional support appear to reduce the mortality rate, and allow spontaneous fistula closure in some patients. Definitive surgical management is performed only after restitution of normal physiology, usually after at least 6 months. Copyright © 2004 British Journal of Surgery Society Ltd.

Methods The current literature is reviewed and the experience of a tertiary referral centre is reported. Results The lecture describes the most typical subsets of non-granulomatous uveitis. Most part of the talk is dedicated to the most common form of non-granulomatous anterior uveitis: the acute anterior uveitis (AAU), which is very often associated with the HLA-B27 allele. This antigen is also typically associated with the spondyloarthropathies, which are inflammatory joint diseases of the vertebral column. The correct interpretation of the clinical pattern can drive the decision towards the right therapeutic strategy. Other uveitis entities are described also. Conclusion Non-granulomatous uveitis is one of the most important ocular inflammations. It is mandatory to pay attention to the clinical findings and to the laboratory work-up, in order to achieve a good therapeutic approach. [source] 2255: Inflammatory neovascular membraneACTA OPHTHALMOLOGICA, Issue 2010P NERI Purpose To describe the most common mistakes in the management of inflammatory choroidal neovascularization (CNV). Methods The current literature is reviewed and the experience of a tertiary referral centre is reported. Results CNV is a potentially sight-threatening sequela of uveitis. Several mistakes can be done during patients examination: CNV might not be recognized both at biomicroscopy and at fluorescein angiography (FA), for instance. Moreover, since some doctors are not aware of the importance of Indocyanine Green Angiography (ICGA), the choroidal involvement during inflammatory CNV might not be appreciated. These are just some examples of possible errors which can be done during the daily practice. The outcome of subfoveal CNV is poor if untreated: several procedures have been considered, even though there is lack of guidelines. The most important mistake can be represented by the lack of criticism on the treatment techniques: several methods have been proposed, albeit some of them should not be used on the basis of the treatment rationale and on the better knowledge of CNV pathophysiology. The presentation shows the most typical cases where the above mentioned mistakes have been done, suggesting some methods in order to avoid them. Conclusion CNV secondary to uveitis is a severe sequela, which can lead to significant visual impairment. Several mistakes can be done during both the diagnosis and the therapeutic procedures. Although no guideline is provided, the current medical literature can give the basis for a successful treatment strategy. [source] Review of 345 eye amputations carried out in the period 1996,2003, at Rigshospitalet, DenmarkACTA OPHTHALMOLOGICA, Issue 2 2010Marie Louise Roed Rasmussen Abstract. Purpose:, The aim of this study was to identify the number of eye amputations, and the causative diagnoses, indications for surgery and surgical techniques applied, and to evaluate a possible change in surgical technique in a tertiary referral centre in Denmark. Methods:, The hospital database was screened using surgery codes for patients who had undergone bulbar evisceration, enucleation or orbital exenteration in the period 1996,2003. Patient records were reviewed for gender, age, time since surgery, causative diagnosis (the disease process leading to the indication for amputation), indication for eye amputation, type of surgery and whether an implant was applied. Results:, A total of 345 patients were identified as having undergone eye amputation during the 8-year period. Indications for eye amputation were: painful blind eye (127); neoplasm (119); infection (42); recent injury (25); disfiguring blind eye (25); prevention of sympathetic ophthalmia (5), and other reasons (2). Surgical procedures included 174 eviscerations, 154 enucleations and 17 orbital exenterations. The mean number of surgeries per year was 43.1. An orbital implant was applied in 168 patients. Conclusions:, The most frequent indications for eye amputation were painful blind eye (37%) and neoplasm (34%). During the study period, the annual number of eye amputations was stable, but an increase in bulbar eviscerations was noticed. Orbital implants were used in 33% of patients in 1996 and 67% in 2003. [source] Progress in the appraisal and management of inflammatory CNVsACTA OPHTHALMOLOGICA, Issue 2009P NERI Purpose To review the current Literature and to describe the experience of a tertiary referral centre on the progress in the appraisal and the management of inflammatory choroidal neovascularization (CNV). Methods The current literature is reviewed and the experience of a tertiary referral centre is reported. Results CNV is a potentially severe sequela of posterior uveitis. The role of chronic inflammation has been described in experimental uveitis. For such reasons, even when biomicroscopy and fluorangiography (FA) cannot detect abnormalities, Indocyanine Green Angiography (ICGA) can show choridal anomalies. ICGA greatly improved the appraisal of the choroidal involvement, by providing reliable data for the diagnosis and for the management of inflammatory CNV. The new spectral domain optical coherence tomography (OCT) equipments can provide further informations that can be useful for a correct clinical assessment. The out-come of subfoveal CNV is poor if untreated: several procedures have been considered, even though there is lack of guidelines. Steroids, both local and systemic, are the first line therapy for non-infectious choroidal inflammation, although their long-term use can lead to unpleasant sequala, such as glaucoma and cataract. Immunesuppressive agents, lasers photocoagulation, photodynamic treatment, surgical removal and anti-Vascular Endothelial Growth Fact (VEGF) are other options. Conclusion CNV secondary to uveitis is a severe sequela leading to significant visual impairment. ICGA is mandatory in order to obtain relevant informations about the choroidal status. Several therapeutic options have been considered, but no guidelines are available at the moment. [source] Adalimumab (Humira®) therapy for uveitisACTA OPHTHALMOLOGICA, Issue 2009P NERI Purpose To review the current Literature and to describe the experience of a tertiary referral centre on Adalimumab (Humira®) therapy for uveitis. Methods The current literature is reviewed and the experience of a tertiary referral centre is reported. Results Chronic non-infectious uveitis (NU) remains one of the most challenging problems in ophthalmology. Often, early and aggressive treatment is needed for a good visual acuity outcome. Local and oral corticosteroids remain the first line of treatment, even though side effects, such as glaucoma, cataract and Cushing Syndrome, can be serious and not tolerable. Therefore, a variety of immunosuppressive agents are in use, such as Cyclophosphamide, Methotrexate, Cyclosporin A, Azathioprine and Mycophenolate mofetil. Recently, new types of drugs, called "biologic agents", are available. In the model of experimental autoimmuneuveitis (EAU) it has been demonstrated that tumor necrosis factor-alpha (TNF-,) may play a key role in uveitis. Beside other anti- TNF-, drugs, Adalimumab (Humira®) is the newest biologic drug available. Adalimumab is a recombinant human IgG1 monoclonal antibody to TNF-, that blocks the TNF-, biologic activity. Adalimumab seems to control uveitis unresponsive to the traditional immunosuppressive agents and, moreover, its subcutaneous administration makes the procedure easier. Conclusion The data in the literature suggest that Adalimumab can be an effective and safe therapy for the uveitis, by controlling inflammation of the eye. The duration of treatment have still to be investigated in larger studies and further trials are mandatory to validate the preliminary data. [source] Mycophenolate mofetil in uveitisACTA OPHTHALMOLOGICA, Issue 2009P NERI Purpose To review the current Literature and to describe the experience of a tertiary referral centre on the use of mycophenolate mofetil (MMF) treatment in uveitis. Methods The current literature is reviewed and the experience of a tertiary referral centre is reported. Results The long-lasting remission in several systemic diseases, such as Crohn's disease, severe atopic dermatitis, Wegener's granulomatosis and microscopic polyangioitis, rheumatoid arthritis, pemphigus vugaris, and psoriasis, have been proven. Recent publications have have recently confirmed the satisfactory control of uveitis with MMF in a large cohort of patients. Moreover, the long-term control of cystoid macular oedema (CMO) unresponsive to the traditional therapy has been described, as well as for the choroidal neovascularization (CNV). Conclusion Non-infectious uveitis is one of the leading causes of visual impairment in ophthalmology. Steroids can control such disease, even though a long-term treatment is not recommended: several complications, such as high blood sugar level, osteoporosis, blood cell abnormalities, cataract and glaucoma, can occur. MMF is a reversible, non competitive, selective inhibitor of the de-novo pathway of purine synthesis; mycophenolic acid has a strong effect to Type II isoform of inosine monophosphate dehydrogenase enzyme, providing a stronger cytostatic effect on lymphocytes than on other cells types, with minor action to Type I expressed in most other cells. The specific action of MMF on selected targets makes it a promising drug for the control of non-infectious intraocular inflammations. [source] Dyskinesias and associated psychiatric disorders following streptococcal infectionsCHILD: CARE, HEALTH AND DEVELOPMENT, Issue 6 2004Richard Reading Dyskinesias and associated psychiatric disorders following streptococcal infections . DaleRC, HeymanI, SurteesRAH, ChurchAJ, GiovannoniG, GoodmanR & NevilleBGR . ( 2004 ) Archives of Disease in Childhood , 89 , 604 , 610 . Background The classical extrapyramidal movement disorder following , haemolytic streptococcus (BHS) infection is Sydenham's chorea (SC). Recently, other post-streptococcal movement disorders have been described, including motor tics and dystonia. Associated emotional and behavioural alteration is characteristic. Aims To describe experience of post-streptococcal dyskinesias and associated comorbid psychiatric features presenting to a tertiary referral centre 1999,2002. Methods In all patients, dyskinetic movement disorders followed BHS pharyngeal infection. BHS infection was defined by pharyngeal culture of the organism, or paired streptococcal serology. Movement disorders were classified according to international criteria, and validated by experienced child neurologists. Psychiatric complications were defined using ICD-10 criteria using a validated psychiatric interview. Results In the 40 patients, the following dyskinetic movement disorders were present: chorea (n = 20), motor tics (n = 16), dystonia (n = 5), tremor (n = 3), stereotypies (n = 2), opsoclonus (n = 2) and myoclonus (n = 1). Sixty-five per cent of, the, chorea, patients, were, female,, whereas, 69% of the tic patients were male. ICD-10 psychiatric diagnoses were made in 62.5%. Using the same psychiatric instrument, only 8.9% of UK children would be expected to have an ICD-10 psychiatric diagnosis. Emotional disorders occurred in 47.5%, including obsessive-compulsive disorder (27.5%), generalized anxiety (25%) and depressive episode (17.5%). Additional psychiatric morbidity included conduct disorders (27.5%) and hyperkinetic disorders (15%). Psychiatric, movement and post-streptococcal autoimmune disorders were commonly observed in family members. At a mean follow-up of 2.7 years, 72.5% had continuing movement and psychiatric disorders. Conclusion Post-streptococcal dyskinesias occur with significant and disabling psychiatric comorbidity and are potential autoimmune models of common ,idiopathic' movement and psychiatric disorders in children. Multiple factors may be involved in disease expression including genetic predisposition, developmental status and the patient's sex. [source] | |||||||||||||||||||||||||||||||
