Influence of age of onset on clinical features in obsessive-compulsive disorder

We compared early-onset and late-onset obsessive-compulsive disorder (OCD) patients in terms of demographic and clinical features. One hundred sixteen outpatients whose primary diagnosis was OCD according to DSM-IV diagnostic criteria were recruited. Early-onset (n=50) and late-onset (n=66) OCD groups were compared with respect to demographic variables and scores obtained on various scales. A male gender predominance was found in early-onset OCD group. Symmetry/exactness obsessions, religious obsessions, hoarding/saving obsessions, and hoarding/collecting compulsions also were significantly more frequent in the early-onset group than in the late-onset group. The results may suggest a phenotypic difference between the two groups. Further studies are needed to investigate the differences between early-onset and late-onset OCD groups to examine the hypothesis that early-onset OCD is a distinct subtype of the disorder.     

A rare association: Castleman's disease and pemphigus vulgaris

Castleman disease is a reactive lymph node hyperplasia of unknown origin that often involving the thorax although it may involve all parts of the body. It is usually seen in young adults and presents an asymptomatic course. It is usually located to anterior and middle mediastinum. Pemphigus vulgaris is a bullous skin disease in which immune mechanisms take place in the pathogenesis. Mouth and oropharynx are the most commonly involved structures. IgG antibodies against the epidermal intracellular structures are essential in the diagnosis. We have wanted to discuss a 28 years old female with the literature review since the association between pemphigus vulgaris and Castleman's disease is rare.     

Deletion analysis and clinical correlations in patients with Xp21 linked muscular dystrophy

We carried out molecular deletion analysis on 142 patients with Duchenne/Becker muscular dystrophy which covered 25 exons of the dystrophin gene. We also evaluated the results by comparing with the clinical findings and examples in the literature. A deletion ratio of 63.7% was achieved. Exon 46 was the most frequently affected region. Interestingly we also observed four cases with muscle promoter (Mp) region deletions which have been rarely reported in the literature.     

A twelve week exercise program improves the psychological status, quality of life and work capacity in hemodialysis patients

BACKGROUND: Patients with chronic renal failure (CRF) are restricted in physical, emotional and social dimensions of life due to their treatment and their comorbid medical conditions. We aimed to evaluate the effects of a 12-week exercise program on the functional capacity, functional mobility, walking capacity, quality of life and depression in patients with renal failure on hemodialysis (HD). METHODS: Twenty patients with renal failure on HD were included and 14 of them completed the study. The patients went through a 12-week exercise program of 90 min/day, 3 days a week. Exercise and walking capacity, functional mobility, psychological status and quality of life were evaluated pre- and post-training. RESULTS: Following the exercise, peak oxygen consumption, exercise duration and peak workload improved significantly (respectively, p=0.006, p=0.002 and p=0.002). There were significant improvements in the sit-to-stand-to-sit test and the 6- min walk test (p<0.001 and p=0.002). There was a significant reduction in the depression score (p<0.001). Both physical component scale (PCS) and mental component scale (MCS) of the Kidney Disease Quality of Life Short-Form 36 (SF-36) questionnaire showed significant increases (respectively, p=0.002 and p=0.004). CONCLUSION: The application of an appropriate exercise program would improve psychological status and quality of life, as well as work capacity in long-term maintenance HD patients.     

Analgesia for adenotonsillectomy in children: a comparison of morphine, ketamine and tramadol

Background : Establishment of good analgesia is of major concern in the postoperative period following adenotonsillectomy. The aim of this study was to compare the effects of ketamine, morphine and tramadol on postoperative pain after adenotonsillectomy in children. Methods : Sixty children (age 5–12 years) scheduled for adenotonsillectomy were randomized into four groups to receive intravenously (i.v.) either 0.5 mg·kg^?1 ketamine hydrochloride (K), 0.1 mg·kg^?1 morphine hydrochloride (M), 1.5 mg·kg^?1 tramadol hydrochloride (T) or normal saline (S) in a volume of 4 ml during induction. After tracheal intubation 10 μg·kg^?1·min^?1 ketamine hydrochloride in group K and 0.6 ml·kg^?1·h^?1 saline i.v. in groups M, K and S were infused peroperatively. Postoperative analgesic requirements and side‐effects were recorded. Pain was assessed by the Numeric Rating Scale (NRS) and the Children's Hospital of Eastern Ontario Pain Scale (CHEOPS) scores. Results : Heart rate increased significantly peroperatively only in group K. NRS at first and fifth minute in group M and at first minute in group T and K and CHEOPS score at first, fifth, 15th and 60th min in group M were found to be significantly lower than in the control group. The time to first analgesic requirement was significantly longer in group M compared with ketamine and the control group. Six children in group M, nine in group T, 11 in group K and 15 in group S needed additional analgesics. Conclusions : Morphine hydrochloride 0.1 mg·kg^?1 i.v. administered during induction of anaesthesia provides efficient pain relief in children undergoing adenotonsillectomy.     

Inhibin alpha and beta expression in ovarian stromal tumors and their histological equivalences

Inhibin is a heterodimeric protein hormone that appears to be a sensitive immunohistochemical marker of sex cord-stromal tumors. Although sex cord-stromal tumors can usually be distinguished from ovarian epithelial tumors or their metastases by morphology or by using antibodies against intermediate filaments, the diagnosis remains difficult in rare situations in such cases as sarcomatoid granulosa-theca cell tumors, ovarian small cell carcinomas, or soft-tissue sarcomas. The purposes of this study were to examine inhibin alpha and beta immunoreactivity in a wide range of gonadal stromal neoplasms and to assess its value in the differential diagnosis of problematic tumors. A total of 108 paraffin-embedded ovarian and extraovarian tumors were examined immunohistochemically by using anti-alpha inhibin and anti-beta inhibin. Inhibin alpha immunostaining was identified in 46 (81%) of 57 gonadal stromal tumors, one (14%) of seven endometrial stromal tumors, and one (50%) of two primary ovarian carcinoid tumors. Inhibin beta immunostaining was detected in 55 (96%) of 57 gonadal stromal tumors, two (29%) of seven endometrial stromal tumors, one (50%) of two dysgerminomas, and in all of two (100%) primary ovarian carcinoid tumors. Inhibin alpha expression was not detected in any ovarian surface epithelial tumor cells. Some surface epithelial tumors showed stromal inhibin alpha (15% of cases) and inhibin beta (48% of cases) positivity. Weak immunoreactivity for inhibin beta was found in most (83% of cases) ovarian surface epithelial tumors. Two ovarian Burkitt lymphomas were negative for inhibin alpha and beta. Inhibin alpha is a sensitive immunohistochemical marker of gonadal stromal tumors and is of value in the differential diagnosis of ovarian neoplasia. Inhibin beta is a nonspecific marker for ovarian neoplasms, showing expression on tumor and stromal cells of different epithelial or stromal tumors.     

Rapid eye movement sleep behavior disorder in parkinsonism with parkin mutations

Rapid eye movement sleep behavior disorder (RBD) in the setting of parkinsonism or dementia often reflects an underlying synucleinopathy. Lewy bodies, intraneuronal aggregates containing abnormal alpha-synuclein, are absent in most cases of parkinsonism with parkin mutations (Park2). We performed clinical history and video-polysomnography in 10 Park2 patients (seven men; age, 51.2 +/- 11.6 years; parkinsonism duration, 18.3 +/- 11.2 years) and found RBD in 6. In all instances, RBD followed the onset of motor symptoms by several years. Our study shows that RBD is frequent in Park2, suggesting that mechanisms other than synuclein deposition can cause RBD in neurodegenerative disorders.     

Gender-related differences among Turkish patients with obsessive-compulsive disorder

The purpose of the present study was to investigate gender-related sociodemographic and clinical differences among Turkish patients with obsessive-compulsive disorder (OCD). A total of 169 patients diagnosed with OCD by DSM-III-R or DSM-IV criteria were included in this study. Male (n = 73) and female (n = 96) OCD patients were compared with respect to the demographic variables and the scores obtained from the Hamilton Rating Scale for Anxiety (HRSA), the Hamilton Rating Scale for Depression (HRSD) and the Yale-Brown Obsessive Compulsive Scale (Y-BOCS). We found a significantly earlier age at onset in male patients. No significant difference in terms of HARS, HDRS, and Y-BOCS scores was detected between the two groups. We observed a significantly higher frequency of contamination obsessions in females, and that of aggression and sexual obsessions in males. There was no significant difference in terms of the frequency of compulsions between the two groups. We also found that compulsion severity on obsessions/compulsions was higher in females and comorbidity rates of social phobia and schizophrenia were higher in males. Considering our results in combination with those of other studies, similarities rather than differences in gender-related sociodemographic and clinical characteristics of OCD patients across different populations seem to be present.
