RESUMO

BACKGROUND: Minimal hepatic encephalopathy can only be detected by specific psychometric or neuropsychological tests. We aimed to determine the prevalence of minimal hepatic encephalopathy in a hepatology outpatient clinic of a tertiary center. METHODS: A total of 82 patients with chronic liver disease were involved prospectively in this study. Control groups consisted of healthy volunteers (n = 123) and chronic renal failure patients (n = 28). We used 2 different methods to detect minimal hepatic encephalopathy. First method was a battery of 5 psychometric tests (number connection tests A and B, digit symbol test, serial dot test, line tracing test) which was filled by all patients. The second method was critical flicker frequency test. Both methods were used in the whole group (n = 233). We applied linear regression analysis to the results of psychometric tests of healthy volunteers to establish equations to calculate the expected values of each test. Test results of the patients were evaluated according to the expected results obtained from these equations. RESULTS: The prevalence of minimal hepatic encephalopathy detected by psychometric tests and critical flicker frequency test was 13% and 14%, respectively. When the positivity of both tests was deemed necessary to diagnose minimal hepatic encephalopathy, the rate of minimal hepatic encephalopathy was 3.6% (n = 3) in a chronic liver disease patient group. CONCLUSION: Minimal hepatic encephalopathy is a difficult clinical condition to diagnose, and it is more appropriate to use psychometric tests and critical flicker frequency test together.

RESUMO

OBJECTIVE: To understand the clinical approach of radiation oncologists during the treatment of patients with breast reconstruction. MATERIALS AND METHODS: A questionnaire survey was emailed to 105 active members of the Turkish Radiation Oncology Society, the Breast Cancer Study Group. The factors associated with radiation oncologists and their current practice was identified. RESULTS: Fifty radiation oncologists (47.6%) responded, and most of the responders (83%) were physicians who treated >50 new breast cancer patients annually. The majority of the physicians worked in academic hospitals and had more than 15 years of work experience. The early reconstruction rate was noted to be low among patients with mastectomy (<10% of the mastectomy patients) (p<0.05). Early implant irradiation with temporary tissue expander was noted to be a more common procedure. The majority of the respondents (68%) preferred to irradiate an inflated implant (20% total, 80% partial). In addition, 22% of the physicians declared that they routinely used bolus and that 60% of them used it only for patients at a high risk of local recurrence factors. CONCLUSION: It can thus be concluded that variations exist between experienced radiation oncologists and others. Hypofractionation is not yet commonly practiced for patients with reconstruction in Turkey. A concrete consensus can be helpful to create a homogeneity in treatment decisions and practical applications.

RESUMO

Objective: The Hamilton Depression Rating Scale (HDRS-17) and the Hamilton Anxiety Rating Scale (HARS-14) have been acknowledged as gold standards in evaluating the severity of depression and anxiety. The specificity and sensitivity of these scales in predicting somatic complaints of depression and anxiety are issues in both clinical and research areas. The present study proposes a new model to enhance the sensitivity and specificity of HDRS-17 and HARS-14 for predicting symptoms of insomnia, inappetence, and loss of libido in psychiatric patients. Methods: This study included 1507 patients diagnosed withbipolar disorder, depression, panic disorder, obsessive-compulsive disorder, and generalized anxiety disorder. The HDRS-17 and the HARS-14 were utilized as predictive scales for the prediction of patients' sleep, appetite, and libido. The sensitivity and specificity were computed using the receiver operating characteristic (ROC). Logistic regression was performed to enhance the predictive values. The predictive value of the logistic regression model was not satisfactory, and a conversion table was therefore designed for each symptom-diagnosis subgroup. The new joint ROC model was then used to recalculate the sensitivity and specificity of the 2 scales for each symptom-diagnosis subgroup. The outcome is a prediction table, presented for use by clinicians. Results: It was observed that the new statistical model, the joint ROC, increased the sensitivity and specificity of the HDRS-17 and the HARS-14. Conclusion: : Based on the results of the evaluations with the HDRS and the HARS, the joint ROC method was developed to better predict the presence of symptoms.

RESUMO

BACKGROUND: Sexual dysfunction is an important side-effect after radiotherapy (RT) for prostate cancer (PCa). The aim of this study was to compare sexual functions of PCa patients before and after intensity-modulated RT and to analyze their correlation with penile bulb (PB) doses and patient characteristics. MATERIALS AND METHODS: Forty-two patients who underwent RT ± hormone therapy for PCa between 2010 and 2013 were analyzed. Sexual functions assessed by patient-reported questionnaire and physician reported scale before and 3 years after treatment. The effect of patients' age, prostate volume, testosterone levels, comorbidity, smoking status, tumor stage, RT technique, hormone therapy, and PB doses to sexual functions were investigated. RESULTS: After 3 years of RT, 64.3% of all patients had a lower erectile score; and 75% of patients who were previously potent (n = 24) had become impotent after treatment. However sexual desire still remained in 75.8% of patients who had desire before treatment (n = 33). Statistical analysis showed that two parameters were correlated with postradiotherapy impotency outcome; PB mean radiation dose (P = 0.033) and testosterone levels (P = 0.032). CONCLUSIONS: RT, despite modern techniques, affects the sexual function of PCa patients in varying degrees. Reducing radiation doses to penile structures may play a role in preventing erectile dysfunction.

RESUMO

PURPOSE: Our objective was to analyze kidney damage using glomerular filtration rate (GFR) and dynamic renal scintigraphy (DRS) compared with dose volume histogram (DVH) parameters in gastric cancer patients. MATERIALS AND METHODS: Twenty-two gastric cancer patients treated with postoperative chemoradiotherapy were retrospectively evaluated. Student's t test was used to compare pre- and posttreatment GFR and creatinine values. The relative contribution of the left and right kidney in DRS results was expressed as left-to-right ratio (L/R), and the percentage of initial and control participation ratio difference was calculated. Spearman's correlation analysis was used to compare the percentage difference of L/R ratio with DVH parameters of each kidney. RESULTS: In DRS analysis, decrease in left kidney cortical function was observed in one patient. V5-V10 of the left and bilateral kidneys were significantly associated with GFR decline. None of the DVH parameter was significantly associated with L/R ratio. However, the V15 and Dmean of the bilateral kidney were significantly correlated with greater decrease in L/R ratio in seven patients whose posttreatment DRS period was > 12 months. CONCLUSIONS: Decline in renal function, even with current renal constraints, was observed. Minimization of V5, V10, and V15 and mean dose (Dmean) to the kidney should be considered.

RESUMO

OBJECTIVES: There is no validated questionnaire in Turkish to assess asthma knowledge. In this study, we aimed to evaluate the reliability and validity of the Turkish version of the Asthma Self-Management Knowledge Questionnaire (AKQ) among asthmatic adults. MATERIAL AND METHODS: The AKQ was translated into Turkish by two medical-text translators, followed by back translation and final review by two clinicians with experience in asthma management. The Turkish Asthma Self-Management Questionnaire was then applied to 202 adult asthma patients, and additional demographic and clinical features of the patients were collected for analysis. RESULTS: The internal reliability of the 24-item AKQ was not high (Cronbach's alpha=0.55). Tukey's test of additivity was significant (p<0.001). This result revealed that all questions are consistent and measure the same concepts. Factor analysis demonstrated a probable structure of 10 factors that together explained 63.7% of total variance in results. Intra-class reliability of the AKQ was quite high. CONCLUSION: This study shows that AKQ seems to be a suitable instrument to evaluate the effect of different components of asthma knowledge - such as triggers, medications, asthma exacerbations, and avoidance measures - in adult asthmatics.

RESUMO

PURPOSE: To evaluate the impact of caseload volume on the outcomes of open and laparoscopic surgery for colorectal cancer. METHODS: Between April 1999 and January 2011, patients who underwent open or laparoscopic resection for colorectal adenocarcinoma with curative intent were identified. There were 2 groups of surgeons, whose primary practice is gastrointestinal surgery (n=5, group A) and general surgery (n=14, group B). Histopathologic and oncologic outcomes, as well as survival data were evaluated. RESULTS: A total of 815 patients fulfilled the study criteria and 356 (group A: 120, group B: 236) patients who had >2 years' follow-up data were included. Colorectal procedures constituted 33% and 19% of all the operations in A and B groups, respectively (P<0.0001). Among the colorectal cases, rates of laparoscopic surgery were 37% and 20% in the group A and B, respectively (P<0.0001). Practice pattern was independently associated with better overall survival and was favoring the group A (P=0.02). CONCLUSIONS: Increased caseload volume improves oncologic outcomes in patients undergoing colorectal resection for nonmetastatic cancer.

RESUMO

INTRODUCTION: Single-photon emission computed tomography (SPECT) myocardial perfusion imaging is an accepted method for reflecting the pathophysiological significance of lesions detected by coronary angiography. However, it has an inherent drawback in terms of false-positive perfusion defects for the inferior myocardial wall. To overcome this problem, different acquisition techniques have been proposed, including the computed tomographic-based attenuation correction method. In this respect, a new imaging technique, left supine lateral position SPECT myocardial perfusion imaging with technetium-99m methoxyisobutylisonitrile (Tc-99m MIBI), has been proposed to eliminate this problem and its value has been investigated in this report. MATERIALS AND METHODS: Sixty-two patients were prospectively and randomly enrolled in this study. They underwent Tc-99m MIBI SPECT in the supine, prone, left lateral, and sitting positions after an adequate stress test on the same day.The presence and extent of defects on stress images were noted in the supine image data set for the 11 myocardial segments, which were then labeled as 1 or 0 if a defect was present or absent, respectively. This evaluation sequence was repeated in all other image data sets. When defects persisted in other scan positions it was regarded as true positive, and when they were resolved they were regarded as false positive. By this means, the percentages of resolving perfusion defects by that imaging position were calculated for each observer per positional pair under comparison. RESULTS: From six interpretations carried out by the nuclear medicine physicians, 6×11×3=198 four-fold tables in 11 segments were analyzed for discrepancies between position pairs. In 31 of 33 discrepant interpretations, defects observed in any of the other positions were resolved in the lateral position. Only in two evaluations of one observer were the discrepancies against lateral positioning for the anterior wall. If the inferior wall was considered alone, it was clearly obvious that lateral positioning was more accurate than the other positions.Intraobserver evaluation showed the methodology to be highly reproducible.The SPECT findings were concordant with coronary angiography results in selected patients. CONCLUSION: Visual and quantitative evaluations of the variation in inferior wall activity lead us to suggest that SPECT imaging with Tc-99m MIBI be performed in the left lateral position to allow better visualization of the inferior and septal walls in those departments not able to utilize computed tomographic attenuation correction.

RESUMO

INTRODUCTION: The full-text publication of abstracts presented at any given scientific meeting in peer-reviewed journals is accepted as a measure of scientific quality of that particular meeting. The aim of this study is to determine the full-text publication rate of abstracts presented at the 2005 Scientific Meeting of the Undersea and Hyperbaric Medical Society (UHMS). METHODS: We identified the scientific abstracts presented at the 2005 UHMS meeting and searched the PubMed database (June 2005 to July 2010) for their corresponding full-text publication. We recorded the following parameters for each of the abstracts: number of authors, number of centers involved in the study, statistical methods used, country of origin of the study, study type, and subject of the abstract. We recorded the time to publication and the title of the journal if the abstract had been published in a peer-reviewed journal. RESULTS: Overall, we identified 187 abstracts presented at the 2005 UHMS meeting. Two of the abstracts were excluded from the study because they had been retracted from the meeting and six more because they had been already published as full-text articles at the time the meeting was held. Of the 179 abstracts, 62 (34.6%) were published as full-text articles within the succeeding five years. The mean (+/- SD) time to publication was 18.5 (+/- 13.6) months. Multivariate analysis with logistic regression identified "country of origin" and "the subject of the abstract" as independent predictors of full-text publication. CONCLUSION: We found that only one-third of the abstracts presented at the 2005 UHMS meeting were published as full-text articles within the succeeding five years. Although this rate is consistent with similar studies from various disciplines, further research is needed to identify the specific barriers to full-text publication of abstracts in the field of underwater and hyperbaric medicine.

RESUMO

Dendritic cell tumors are extremely rare and current knowledge on these tumors is limited. The characteristics of three dendritic cell sarcoma subtypes and their optimal treatment approaches are not fully clarified. We aimed to make a systematic review of the literature and enrich the current data with five new cases. Pooled analysis of 462 reported cases revealed that the tumor had no age, gender or racial predilection. Our analysis suggests that the young age, advanced stage, intraabdominal involvement and unfavorable histological features (i.e. large tumor size, absence of lymphoplasmacytic infiltration, coagulative necrosis, high mitotic count) may predict poor prognosis. Subtypes of this tumor have different clinical behaviors with interdigitating dendritic cell sarcoma being the most aggressive form. In general, surgery is the most effective treatment modality and adjuvant radiotherapy has no significant effect on overall survival of patients. The role of chemotherapy for the management of advanced disease is controversial.

RESUMO

To study the prevalence major rheumatic diseases in western Turkey. This survey was conducted in Havsa which have a total population of 18,771. Physicians and interns visited every household, interviewed face to face a questionnaire about the symptoms of rheumatic disorders. The individuals replied positively to any question were examined at the nearest health center. Those have no objective findings related to any rheumatic diseases were excluded. People could not be clinically diagnosed were asked to come to the hospital for further evaluation. A total 17,835 of 18,771 residents participated. We estimated the prevalence of Behçet's Disease (BD) as 0.019%; ankylosing spondylitis: 0.120%; rheumatoid arthritis: 0.321%; knee osteoarthritis (OA): 5.351%; hand OA: 1.110%; hand and knee OA: 1.958%; total OA: 8.420%; primary Raynaud's: 1.192%; psoriasis: 0.424 %; psoriatic arthritis: 0.050%; rheumatic fever: 0.318%; rheumatic heart disease: 0.200%; inflammatory bowel disease: 0.023%; lupus: 0.059%; gout: 0.018%; systemic sclerosis: 0.022%; juvenile rheumatoid arthritis: 0.032%; temporal arteritis: 0.020%, and familial Mediterranean fever (FMF) as 0.006%. Figures were adjusted for age-sex of the general Turkish population. The prevalence's of BD and FMF are considerably lower in Havsa as compared to other regions in Turkey.

RESUMO

The aims of this study were to determine the prevalence of H. pylori seropositivity in patients with psoriasis, to evaluate the relationship between PASI (Psoriasis Area and Severity Index) scores and H. pylori infection, and to assess the impact of H. pylori infection on the response to treatment. A total of 300 patients with psoriasis and 150 non-psoriatic healthy controls were enrolled in the study. Patient PASI scores were recorded and H. pylori stool antigen tests performed in both patients and controls. Fifty patients with H. pylori infections were randomly assigned to one of two groups, one of which received acitretin with H. pylori treatment and the other acitretin alone. Statistical analyses were performed using chi-square and logistic regression tests. PASI scores were significantly higher in patients with H. pylori infections. Treatment aimed at eradicating H. pylori infection enhanced the effectiveness of acitretin therapy and shortened response times. Our results suggest that H. pylori infection plays a role in the severity of psoriasis, and that eradicating such infections enhances the effectiveness of psoriasis treatment.

RESUMO

BACKGROUND: To establish recurrence patterns among locally advanced head and neck non-nasopharyngeal squamous cell carcinoma (HNSCC) patients treated with radical (chemo-) radiotherapy and to correlate the sites of loco-regional recurrence with radiotherapy doses and target volumes METHOD: 151 locally advanced HNSCC patients were treated between 2004-2005 using radical three-dimensional conformal radiotherapy. Patients with prior surgery to the primary tumour site were excluded. The sites of locoregional relapses were correlated with radiotherapy plans by the radiologist and a planning dosimetrist. RESULTS: Median age was 59 years (range:34-89). 35 patients had stage III disease, 116 patients had stage IV A/B. 36 patients were treated with radiotherapy alone, 42 with induction chemotherapy, 63 with induction and concomitant chemoradiotherapy and 10 concomitant chemoradiotherapy. Median follow-up was 38 months (range 3-62). 3-year cause specific survival was 66.8%. 125 of 151 (82.8%) achieved a complete response to treatment. Amongst these 125 there were 20 local-regional recurrence, comprising 8 local, 5 regional and 7 simultaneous local and regional; synchronous distant metastases occurred in 7 of the 20. 9 patients developed distant metastases in the absence of locoregional failure. For the 14 local recurrences with planning data available, 12 were in-field, 1 was marginal, and 1 was out-of-field. Of the 11 regional failures with planning data available, 7 were in-field, 1 was marginal and 3 were out-of-field recurrences. CONCLUSION: The majority of failures following non-surgical treatment for locally advanced HNSCC were loco-regional, within the radiotherapy target volume. Improving locoregional control remains a high priority.

RESUMO

The aim of this study was to determine the prevalence of diabetic peripheral neuropathy (DPN) and neuropathic pain in diabetic patients attending university outpatient clinics in Turkey. In this multicenter cross-sectional study, neurologic examinations and nerve conduction studies along with clinical diabetic neuropathy score, and Leeds Assessment of Neuropathic Symptoms and Signs pain scale were performed on 1,113 patients (46.2% male) from 14 centers. Prevalence of DPN determined only by clinical examination was 40.4% and increased to 62.2%, by combining nerve conduction studies with clinical examination. According to Leeds Assessment of Neuropathic Symptoms and Signs scores, neuropathic pain prevalence was 16.0% in those who reported pain. Poor glycemic control, retinopathy, microalbuminuria, hyperlipidemia, diabetic foot, and foot amputation were more commonly observed in patients with DPN. Clinical DPN affected 40.4% of diabetic patients, and neuropathic pain prevalence in diabetic patient population was 14.0%. Clinical examinations and nerve conduction studies are important components for early detection and accurate diagnosis of DPN and painful DPN.

RESUMO

OBJECTIVES: We evaluated the impact of diabetes mellitus (DM) and/or coronary artery disease (CAD) on cardiovascular endpoints in a cohort of hypertensive patients. STUDY DESIGN: The Vascular Risk Study is a cross-sectional, multicenter, observational study conducted among 5,600 patients from various regions of Turkey. This analysis included 2,664 patients (1,643 women, 1,021 men; mean age 65.3 years; range 55-99 years) whose follow-up data were adequate among a population of 4,506 hypertensive subjects. Cardiovascular primary and secondary endpoints at the end of a five-year follow-up were assessed in patients who had hypertension alone, and in those having DM and/or CAD. Information on the cause of death was obtained from the relatives of the patients by follow-up phone calls. RESULTS: There were 1,171 patients (44%) with isolated hypertension, 631 (23.7%) with DM, 530 (19.9%) with CAD, and 332 (12.5%) with both DM and CAD. The presence of either DM or CAD was associated with significant increases in the incidences of all endpoints. The occurrences of primary and secondary endpoints, cardiovascular death, and all death were similar in hypertensive patients who had DM without CAD and in patients who had CAD without DM. In survival analysis, the incidence of cardiovascular death was lowest (5.7%) in hypertensive patients without DM and CAD, and highest (18.4%) in hypertensive patients with DM and CAD. The cumulative survival rates were similar in hypertensive patients with either DM or CAD alone (p>0.05). CONCLUSION: This study demonstrated that the level of cardiovascular risk associated with DM was equal to the risk associated with CAD in hypertensive patients and that the coexistence of DM and CAD in these patients increases the risk geometrically.

RESUMO

Adhesion molecules have a role in many vasculitic disorders. Our aim was to evaluate the status of adhesion molecules in nodular lesions of Behçet syndrome (BS) and compare them with results for the 2 most common types of panniculitis, erythema nodosum (EN) and nodular vasculitis (NV). We included the data for 28 patients with nodular lesions of BS, 24 with EN, and 22 with NV. A panel of monoclonal antibodies against E-selectin, P-selectin, vascular cell adhesion molecule-1, platelet endothelial cell adhesion molecule-1, and intercellular adhesion molecule (ICAM)-1 were applied. The distribution and intensity of adhesion molecules were assessed. There were no statistically significant differences between the BS and control groups in regard to these adhesion molecules except for ICAM-1. The percentage of strongly ICAM-1-stained endothelial cells in subcutaneous fat tissue in relation to the total number of endothelial cells was the lowest in BS (P= .0208). Because many lesions of BS were related to an enhanced inflammatory response, the lower percentage of ICAM-1 expression seems counterintuitive.

RESUMO

BACKGROUND: No study has been conducted on the scientific quality of randomized controlled trials (RCTs) in the cancer field. Our objective was to determine whether adherence to the Consolidated Standards for Reporting Trials (CONSORT) statement is associated with scientific properties of RCT reports from two leading cancer journals. METHODS: We conducted an observational study of RCTs published between 2002 and 2004 in two leading cancer journals that did not endorse the CONSORT statement during that period. We determined the adherence rates with confidence intervals of 33 RCTs according to the 19 methodological items of the CONSORT statement. Each RCT was blindly assessed by three independent evaluators; then the evaluators examined all judgments sequentially and obtained a consensus regarding each methodological item of the CONSORT statement. RESULTS: The average adherence of these 33 RCTs to the 19 methodological items of the CONSORT statement was 79.3% (95% CI, 75.3-83.4%). Most descriptors from the checklist were determined to be methodologically adequate except sequence generation (56.1%; 95% CI, 40.9-71.3%), allocation concealment (27.3%; 95% CI, 13.2-41.4%), implementation (7.6%; 95% CI, 0.0-15.4%), blinding (30.3%; 95% CI, 14.4-46.3%) and sample size (74.2%; 95% CI, 59.5-89.0%). Of all CONSORT checklist items, randomization implementation was the most often omitted. CONCLUSION: Some key methodological items of the CONSORT statement seem poorly addressed in RCTs from these leading cancer journals. Thus researchers should be urged to conform to the CONSORT statement when reporting on RCTs, and the poorly addressed items of the CONSORT statement should be reevaluated for RCTs already reported.

RESUMO

Clinical studies are usually performed with the aim of justifying that a new treatment approach is "superior" to the common standard approach (active control) with respect to benefits. In a general sense, this justification is carried out on the basis of the "null hypothesis significance test" with the P value based on this test used for justification. Today, new drugs differ so little from existing ones that factors such as cost and side effects affect the choice of therapy, when the bioavailability of treatment methods are found equivalent. Therefore, the aim of comparative clinical trials has extended beyond showing that a treatment is "superior" and now attempts to show that new treatments are "equal" and "non-inferior" to existing treatments. New approaches have become necessary since the classical null hypothesis approach is insufficient to justify the use of new agents, especially in cases of "equivalence" and "non-inferiority". This new approach to justification makes use of the "clinical equivalence interval", which determines the limits of the differences between specific endpoints that can be regarded as clinically "equal" to the value that was pre-specified based on studies of established therapies. It also makes use of the quantitative-based "confidence intervals" as the criteria for statistical justification. Many analyses can be done confidently when these tools are applied and the data are interpreted correctly.

RESUMO

The purpose of this study was to assess the prevalence of female urinary incontinence (UI) and risk factors of bothersomeness and help-seeking behavior of hidden female UI in urology and obstetrics and gynecology outpatient clinics. This multicentric and cross-sectional study was conducted as a part of the Turkish Overactive Bladder Study. Female patients (n = 5,565) who were referred with complaints other than UI and overactive bladder symptoms were surveyed using the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) with supplementation of five more questions. The crude prevalence of UI was found to be 35.7%. The prevalence of frequent and severe incontinence was 8.2 and 6.8%, respectively. The mean age of incontinent patients was significantly higher (p < 0.001). The prevalence of stress, urge, and mixed UI was 39.8, 24.8, and 28.9%, respectively. More than half (53%) of incontinent patients were not bothered by UI, and only 12% of incontinent patients had previously sought medical help for their problem. Frequency, severity, and type of UI were independent factors for predicting bothersome UI, while only bothersomeness increased help-seeking behavior. The ICIQ-SF score of 8 has been found to be the best cutoff value to delineate the bothersome UI. Although the crude prevalence of female UI was found to be high, bothersome UI was not so common. The majority of incontinent female patients did not seek medical help. Frequency, severity, and mixed type of UI were found to be the determinants of bothersome UI for which the ICIQ-SF cutoff score of 8 was obtained.
