Selected AbstractsGuidelines for the Management of Squamous Cell Carcinoma in Organ Transplant RecipientsDERMATOLOGIC SURGERY, Issue 4p2 2004Thomas Stasko MD Background. Solid-organ transplant recipients have a high incidence of cutaneous squamous cell carcinoma (SCC) and often develop multiple and aggressive tumors. There are few published studies or reviews, which provide guidance to the clinician in the treatment of these patients. Objective. The objective was to develop useful clinical guidelines for the treatment of skin cancer in organ transplant recipients (OTRs). Methods. The members of the Guidelines Committee of the International Transplant,Skin Cancer Collaborative (ITSCC) carried out a computerized search utilizing the databases of the National Library of Medicine for reports in the literature on SCC in OTRs. These reports were collectively examined by the group and combined with experiences from the members' clinical practices in the development of the guidelines. Results. More than 300 articles relating to SCC in OTRs were reviewed. In general, reports concerning the prevention and treatment of SCC in OTRs are of individual cases or small case series. They are retrospective in nature, statistically nonrigorous, and lack the complete epidemiologic data necessary to derive definitive conclusions. Combining these studies and collective clinical experience, however, is at present the best available method for devising guidelines for the treatment of SCC in OTRs. Conclusion. Guidelines developed for the treatment of skin cancer in OTRs, supported by the best available data and collective clinical experience, may assist in the management of OTRs with SCC. The development of clinical pathways and complete documentation with rigorous prospective study is necessary to improve and refine future guideline development. [source] Novel antipsychotics in bipolar and schizoaffective maniaACTA PSYCHIATRICA SCANDINAVICA, Issue 6 2004G. J. R. Mensink Objective:, Novel antipsychotics are increasingly used in the treatment of bipolar and schizoaffective mania. This paper presents an overview of the controlled studies in this field. Method:, Using cross-references, a computerized search was performed on MEDLINE and EMBASE psychiatry covering the period 1990,2002. Results:, Olanzapine and risperidone, added to mood stabilizers, and olanzapine as monotherapy enjoy the most evidential support in terms of efficacy and side-effect profile for their use in acute bipolar mania. The use of modern antipsychotics in bipolar prophylaxis and in both the short- and long-term treatment of schizomania has not been widely studied yet. Conclusion:, More controlled trials are still needed comparing modern antipsychotics as monotherapy and adjunctive to mood stabilizers with conventional antipsychotics, lithium, anticonvulsants and with each other in short-term and, especially, maintenance treatment of (schizo)mania. Partly based on controlled studies, olanzapine, risperidone and other modern antipsychotics could become preferable for these indications. [source] Fine-needle aspiration of primary osseous lesions: A cost effectiveness studyDIAGNOSTIC CYTOPATHOLOGY, Issue 4 2010Lester J. Layfield M.D. Abstract Fine-needle aspiration (FNA) is not widely used in the work-up of osseous lesions because of concerns regarding its high incidence of nondiagnostic specimens. Although several studies have shown that FNA is less expensive than surgical biopsy, the authors are aware of only one prior study evaluating the cost effectiveness of FNA, which includes the cost of incisional or core needle biopsies necessary to establish a diagnosis when the initial FNA was noncontributory. A computerized search of the pathology records of three medical centers was performed to obtain all FNAs of primary osseous lesions. For each FNA case, all subsequent core needle, incisional or excisional biopsies were recorded as was the result of the definitive operative procedure. The cost of obtaining the definitive diagnosis was calculated for each case including the cost of FNA, imaging guidance utilized, and cost of subsequent surgical biopsy when necessary. The cost of an alternate approach using only surgical biopsy was calculated. The average per patient costs of these two protocols were compared. A total of 165 primary bone tumors underwent FNA. One hundred six of these yielded a definitive cytologic diagnosis. In 59 cases, FNA yielded a result insufficient for definitive therapy necessitating surgical biopsy. FNA investigation of the 165 bone lesions cost 575,932 (average of 3,490 per patient). Surgical biopsy alone would have cost 5,760 per patient. FNA resulted in a cost savings of 2,215 per patient.

[source] Papillary thyroid carcinoma with atypical histiocytoid cells on fine-needle aspirationDIAGNOSTIC CYTOPATHOLOGY, Issue 4 2009Manju Harshan M.D. Abstract Although papillary thyroid carcinoma (PTC) usually has classic cytological characteristics on fine-needle aspiration (FNA), it can present rarely with aberrant features resembling those of histiocytes in a cystic nodule. The aim of the current study was to describe PTC with atypical histiocytoid cells and distinguish it from benign histiocytes. A retrospective computerized search for FNAs with atypical features suggestive of PTC and cystic degeneration was performed, and if available, the corresponding resection specimens were compared. Four cases met the criteria for FNAs and three had surgical pathology follow-up, which showed PTC. One aspirate had some features typical of PTC, but the remaining FNAs had atypical histiocytoid cells, which had traits intermediate between those of PTC and histiocytes. Large cell size, pseudoinclusions, nuclear grooves, and multiple well-defined vacuoles in atypical histiocytoid cells favor PTC over benign histiocytes. Ancillary immunocytochemical studies can also be useful in confirming the diagnosis. Histiocytic cells are frequently present in thyroid aspirates, and occasionally, they have atypical features that represent an unusual presentation of PTC. Closer examination of these cells can provide diagnostic clues for preventing false-negative diagnosis of PTC. Diagn. Cytopathol. 2009. © 2009 Wiley-Liss, Inc. [source] Alcohol and injuries: a review of international emergency room studies since 1995DRUG AND ALCOHOL REVIEW, Issue 2 2007CHERYL J. CHERPITEL Abstract This paper provides a review of emergency room (ER) studies on alcohol and injury, using representative probability samples of adult injury patients, and focuses on the scope and burden of the problem as measured by estimated blood alcohol concentration (BAC) at the time of the ER visit, self-report drinking prior to injury, violence-related injury and alcohol use disorders. A computerized search of the English-language literature on MEDLINE, PsychINFO and the National Institute on Alcohol Abuse and Alcoholism (NIAAA) Alcohol and Alcohol Problems Science Database (ETOH) was conducted for articles published between 1995 and 2005, using the following key descriptors: (1) emergency room/emergency department/accident and emergency, (2) alcohol/drinking and (3) injuries (intentional and unintentional). Findings support prior reviews, with injured patients more likely to be positive for BAC and report drinking prior to injury than non-injured, and with the magnitude of the association substantially increased for violence-related injuries compared to non-violence-related injuries. Indicators of alcohol use disorders did not show a strong association with injury. Findings were not homogeneous across studies, however, and contextual variables, including study-level detrimental drinking pattern, explained some of the variation. This review represents a broader range of ER studies than that reported previously, across both developed and developing countries, and has added to our knowledge base in relation to the influence of contextual variables on the alcohol-injury relationship. Future research on alcohol and injury should focus on obtaining representative samples of ER patients, with special attention to both acute and chronic alcohol use, and to organisational and socio-cultural variables that may influence findings across studies. In-depth patient interviews may also be useful for a better understanding of drinking in the injury event and associated circumstances. [source] Oral health-related quality of life in children: Part I. How well do children know themselves?INTERNATIONAL JOURNAL OF DENTAL HYGIENE, Issue 2 2008A systematic review Abstract:, Objective:, Paediatric oral disorders are likely to have a negative effect on the quality of life. Until recently, children's oral health-related quality of life (OHRQoL) was measured using parents as informants. Instruments have now been developed, which have demonstrated that with appropriate questionnaire techniques, valid and reliable information can be obtained from children. The aim of this study was to make a systematic review of the existing literature about child perceptions of OHRQoL and their validation. Methods:, A computerized search was conducted using Medline, ISI, Lilacs and Scielo for children's perception of OHRQoL. The inclusion criteria were: the articles should contain well-validated instruments and provide child perceptions of OHRQoL. Results:, From 89 records found, 13 fulfilled the criteria. All studies included in the critical appraisal of the project suggested good construct validity of overall child perceptions of OHRQoL. However, children's understanding of oral health and well-being are also affected by variables (age, age-related experiences, gender, race, education, culture, experiences related to oral conditions, opportunities for treatment, childhood period of changes, back-translating questionnaire, children self-perceived treatment need). Conclusions:, The structure of children's self-concept and health cognition is age-dependent as a result of their continuous cognitive, emotional, social and language development. By using appropriate questionnaire techniques, valid and reliable information can be obtained from children concerning their OHRQoL. [source] Meta-analysis of the effects of respiratory rehabilitation programmes on exercise capacity in accordance with programme characteristicsJOURNAL OF CLINICAL NURSING, Issue 1 2007HyunSoo Oh PhD Aims and objectives., This study was performed to investigate the effects of respiratory rehabilitation programmes on exercise capacity in terms of the programme type, the protocol used and other programme characteristics. Background., As the suitable rehabilitation programmes have not been specified, diverse programmes are provided in clinics. Design., Meta-analysis of the primary study results Methods., A computerized search through MEDLINE and CINHAL in addition to tracking down references cited in bibliographies of primarily searched studies were performed to obtain sample studies. Finally 19 research reports were examined. Results., The results of meta-regression showed that the combined effect size of the programmes on exercise capacity was unaffected by forced expiratory volume (in one second), age, the duration and frequency of the programme, or study quality. In addition, the results of meta- anova indicated that the combined effect size was not affected by (i) whether a programme was hospital based or not, (ii) whether a programme was lower-extremity or combined low- and upper-extremity exercise training, (iii) measurement time, and (iv) exercise intensity. Conclusions., The effects of programmes on exercise capacity were not differed in terms of the places where rehabilitation programmes were applied, programme content, measurement time, exercise target sites of body, and the duration and frequency of the programme. Relevance to clinical practice., The results of the present study can provide objective data when constructed or applied on a respiratory rehabilitation programme in clinics. [source] Use of exogenous erythropoietin in critically ill patientsJOURNAL OF CLINICAL PHARMACY & THERAPEUTICS, Issue 3 2004R. MacLaren PharmD Summary Objective:, Review the literature regarding the use of recombinant human erythropoietin (rHuEPO) to prevent red blood cell (RBC) transfusion in critically ill patients. Data sources:, A computerized search of MEDLINE and EMBASE from 1966 through June 2003 was conducted using the terms erythropoietin, anemia, hemoglobin, critical care, intensive care, surgery, trauma, burn, and transfusion. References of selected articles were reviewed. A manual search of critical care, surgery, trauma, burn, hematology, and pharmacy journals was conducted to identify relevant abstracts. Results:, Six randomized studies have evaluated exogenous administration of erythropoietin to prevent RBC transfusions in critically ill patients. Studies vary with respect to rHuEPO dosage regimens, dose of concurrently administered iron, patient characteristics, and transfusion thresholds. Administration of rHuEPO rapidly produces erythropoiesis to reduce the need for RBC transfusions. The largest study conducted to date used weekly rHuEPO administration and found a modest decrease in transfusion requirements although the time to first transfusion was delayed. Reduced intensive care unit (ICU) length of stay (LOS) was shown in only one study of surgical/trauma patients. Reduced LOS after ICU discharge was found in another study of severely ill patients (APACHE II score >22). Other clinical outcomes were not altered by rHuEPO use. No adverse events were associated with rHuEPO use although studies were not designed to evaluate safety. Conclusions:, rHuEPO reduces the need for transfusions. A cost-effectiveness analysis of rHuEPO for this indication is needed. Defining an optimal dosage regimen, identifying patients most likely to respond to rHuEPO, and determining risk factors for ICU associated anaemia would provide information for appropriate rHuEPO utilization. [source] Evidence for benefit of transversus abdominis training alone or in combination with pelvic floor muscle training to treat female urinary incontinence: A systematic review,,NEUROUROLOGY AND URODYNAMICS, Issue 5 2009Kari Bø Abstract Aims Pelvic floor muscle training (PFMT) has Level A evidence to treat female urinary incontinence (UI). Recently, indirect training of the pelvic floor muscles (PFM) via the transversus abdominis muscle (TrA) has been suggested as a new method to treat UI. The aim of this article is to discuss whether there is evidence for a synergistic co-contraction between TrA and PFM in women with UI, whether TrA contraction is as effective, or more effective than PFMT in treating UI and whether there is evidence to recommend TrA training as an intervention strategy. Methods A computerized search on PubMed, and hand searching in proceedings from the meetings of the World Confederation of Physical Therapy (1993,2007), International Continence Society and International Urogynecology Association (1990,2007) were performed. Results While a co-contraction of the TrA normally occurs with PFM contraction, there is evidence that a co-contraction of the PFM with TrA contraction can be lost or altered in women with UI. No randomized controlled trials (RCTs) were found comparing TrA training with untreated controls or sham. Two RCTs have shown no additional effect of adding TrA training to PFMT in the treatment of UI. Conclusions To date there is insufficient evidence for the use of TrA training instead of or in addition to PFMT for women with UI. Neurourol. Urodyn. 28:368,373, 2009. © 2009 Wiley-Liss, Inc. [source] Cutaneous melanoma in New Zealand: 2000,2004ANZ JOURNAL OF SURGERY, Issue 5 2010Jennifer J. C. Liang Abstract Background:, In 2004, we published data on the trends in New Zealand (NZ) cutaneous melanoma (CM) for the period 1995,1999. The present report documents the trends in the next period from 2000 to 2004. Method:, Data were obtained from the New Zealand Cancer Registry by way of a computerized search of CM ICD-10 (172) codes from 2000 to 2004. Only one registration per person was made to avoid including patients with metastatic melanoma. The exclusion criteria were: incorrect or absent data; benign naevi; and melanoma in situ. Incidence rates were age standardised to the Segi world population. Results:, The total study population was 8262 patients. There was no increase found in the overall incidence rate over the time period, but men had a statistically higher overall incidence rate (P= 0.0002) and thicker CMs (P= 0.003) compared with women. This gender difference was particularly marked in those patients aged greater than 59 years. Breslow thickness increased from 0.7 to 0.8 mm. The incidence rates varied quite significantly among District Health Boards, with Taranaki having the highest rate (70.3/100 000/year) and Southland had the lowest rate (20.1/100 000). Overall, NZ had a CM incidence rate of 41.2/100 000/year). Conclusion:, The current study confirmed that NZ has the highest overall CM incidence rate in the world. Elderly men (>59 years old) have the highest risk of developing melanoma. The increase in melanoma thickness with its associated higher mortality risk is of grave concern. [source] LAPAROSCOPIC HEPATECTOMY, A SYSTEMATIC REVIEWANZ JOURNAL OF SURGERY, Issue 11 2007Jerome M. Laurence This systematic review was undertaken to assess the published evidence for the safety, feasibility and reproducibility of laparoscopic liver resection. A computerized search of the Medline and Embase databases identified 28 non-duplicated studies including 703 patients in whom laparoscopic hepatectomy was attempted. Pooled data were examined for information on the patients, lesions, complications and outcome. The most common procedures were wedge resection (35.1%), segmentectomy (21.7%) and left lateral segmentectomy (20.9%). Formal right hepatectomy constituted less than 4% of the reported resections. The conversion and complication rates were 8.1% and 17.6%, respectively. The mortality rate over all these studies was 0.8% and the median (range) hospital stay 7.8 days (2,15.3 days). Eight case,control studies were analysed and although some identified significant reductions in-hospital stay, time to first ambulation after surgery and blood loss, none showed a reduction in complication or mortality rate for laparoscopically carried out resections. It is clear that certain types of laparoscopic resection are feasible and safe when carried out by appropriately skilled surgeons. Further work is needed to determine whether these conclusions can be generalized to include formal right hepatectomy. [source] Prevention of relapse and interventions for enhancing medication adherence in schizophrenia: An East Asian perspectiveASIA-PACIFIC PSYCHIATRY, Issue 2 2010Salleh Mohd Razali MPM FAMM Abstract Introduction: Studies investigating the efficacy of interventions for improving treatment non-adherence in schizophrenia have generated contrasting findings. The present review examined psychosocial interventions for improving medication adherence and prevention of relapse among patients with schizophrenia in developing countries in the Asia-Pacific. Methods: The relevant literature and systematic review were identified by computerized searches using keywords, and hand-searched for other selected articles. Results: The reasons for poor medication adherence were complex and heterogenous. Psychoeducation programs alone are ineffective in achieving good medication adherence because they do not lead to attitudinal and behavioral changes. The greatest improvement in adherence was seen with interventions employing a combination of educational, behavioral and cognitive strategies. Unfortunately, few relevant studies from this region were found. There were some interventions related to psychoeducation and compliance therapy (CT) that were successfully conducted by nurses. Patients in developing countries generally had better family support, but strong stigma towards mental illness and interference by traditional healers led to poor treatment adherence. Lack of facilities and shortage of medical professionals aggravated the situation. Discussion: Intervention to improve treatment adherence and prevention of relapse among patients with schizophrenia should be incorporated into existing psychiatric services. Adherence to treatment in patients with schizophrenia could be improved if continuously supported and monitored by caregivers and treating doctors, to facilitate a change in the patient's attitude. Paramedical personnel, such as psychiatric nurses, could be actively involved in intervention programs because of the shortage of medical professionals in this region. [source] | ||||||||||
