Prevalence and symptomatology of comorbid obsessive-compulsive disorder among bulimic patients

This study sought to assess the prevalence and symptomatology of comorbid obsessive-compulsive disorder (OCD) among Japanese subjects who met the DSM-III-R criteria for bulimia nervosa (BN). The Structured Clinical Interview for DSM-III-R Patient Version was used to distinguish 26 BN patients with concurrent OCD from 52 BN patients without OCD. Obsessive-compulsive symptoms in BN subjects with concurrent OCD were evaluated using the Japanese version of the Yale-Brown Obsessive-Compulsive Scale. There were no differences in the prevalence of concurrent OCD between BN subjects with and without a lifetime history of anorexia nervosa. Among BN subjects with concurrent OCD, symptoms related to symmetry and order were most frequently identified, followed by contamination and aggressive obsessions, and checking and cleaning/washing compulsions. Bulimia nervosa subjects with concurrent OCD were more likely than subjects without OCD to have more severe mood and core eating disorder psychopathology. Comorbid OCD is a common phenomenon in Japanese bulimics (33%) similar to that suggested in BN subjects in the Western countries. Obsessive-compulsive symptoms related to symmetry and order were most frequently observed in BN subjects with concurrent OCD, which was a similar finding to that reported among restricting anorexic subjects.     

Serum C-reactive protein level and the impact of cytoreductive surgery in patients with metastatic renal cell carcinoma

PURPOSE: The prognosis of metastatic renal cell carcinoma is extremely poor. In this type of metastatic tumor cytoreductive surgery of the primary tumor is often performed to confirm the histological type or improve the response to immunotherapy with agents such as interferon or interleukin-2. However, the timing and impact of cytoreductive surgery on the success of immunotherapy require further study. We determined the type of metastatic renal cell carcinoma for which cytoreductive surgery is beneficial. MATERIALS AND METHODS: We retrospectively reviewed the records of 58 patients in whom metastatic renal cell carcinoma was diagnosed at our hospital between 1986 and 1997. Three patients were excluded from study because they were judged to be poor candidates for surgery due to poor performance status. Of the remaining 55 patients 34 consented to cytoreductive surgery of the primary tumor and 21 did not. All except 1 patient were treated with interferon therapy. We evaluated the association of pretreatment serum C-reactive protein and the effect of surgery. RESULTS: We noted no significant difference in age at diagnosis, pretreatment serum immunosuppressive acidic protein, site of metastasis or performance status in 34 patients who underwent cytoreductive surgery and 21 who did not. Of the 21 patients in whom pretreatment serum C-reactive protein was within normal limits (less than 1.0 ng./ml.) no significant difference in disease specific survival was observed in those who did and did not undergo surgery (p = 0.4133). On the other hand, of 34 patients in whom pretreatment serum C-reactive protein was elevated (1.0 ng./ml. or greater) the prognosis was significantly better in those who did versus those who did not undergo surgery (p = 0.0054). Particularly the prognosis in patients in whom postoperative nadir C-reactive protein decreased to within normal limits was markedly better than in those in whom it remained elevated (p = 0.0025). CONCLUSIONS: Our study suggests that cytoreductive surgery is beneficial to patients in whom pretreatment serum C-reactive protein is elevated. Particularly, those in whom serum C-reactive protein decreases to within normal limits may expect longer survival when surgery is combined with postoperative immunotherapy. Currently to our knowledge the prognostic factor that predicts postoperative nadir C-reactive protein has not been identified, indicating that cytoreductive surgery of the primary tumor should be performed in patients with elevated pretreatment C-reactive protein and as performance status permits.

A Japanese patient with frontotemporal dementia and parkinsonism by a tau P301S mutation

The authors report a patient carrying a missense mutation in exon 10 of tau that causes a substitution at codon 301 (P301S). Although the patient shares the rapidly progressive frontotemporal dementia of the other reported pedigrees with P301S, the clinical phenotype is unique in that parkinsonism was a major symptom in the early stage and because behavioral symptoms with dementia became prominent 2 years after the onset of the disease. This study substantiates the notion that tau mutations at codon 301 can show various phenotypes.     

A new fibular osteotomy in association with high tibial osteotomy (a comparative study with conventional mid-third fibular osteotomy)

A new technique for dividing the fibula when performing a high tibial osteotomy is described. The head of the fibula is enucleated and morselized. The technique is simple and safe with a low complication rate.

Résumé  En cas d’ostéotomie supérieure du tibia, nous décrivons une nouvelle technique d’ostéotomie péronière avec énucléation et morcellement de la tête du péroné. On peut employer pour ce faire la même incision cutanée que pour l’ostéotomie du tibia. L’incidence de complications est faible.

Treatment of ununited fracture of the hook of hamate by low-intensity pulsed ultrasound: a case report

A patient presented 4 months after sustaining a fracture of the hook of hamate. X-rays and computed tomography scanning of the carpal tunnel confirmed the presence of an ununited fracture. Low-intensity ultrasound was applied to the fracture site. After 4.5 months of exposure to ultrasound, union was confirmed by both x-rays and computed tomography scanning of the carpal tunnel.

Regulation of p27 by S-phase kinase-associated protein 2 is associated with aggressiveness in non-small-cell lung cancer.

PURPOSE: The F-box protein S-phase kinase-associated protein 2 (Skp2) is one of the positive regulators of the cell cycle that promote ubiquitin-mediated proteolysis of the cyclin-dependent kinase inhibitor p27. In this study, we investigated the significance of Skp2 expression in human non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Clinicopathologic features and immunohistochemical expression of Skp2 and p27 proteins were studied in 138 patients with NSCLC. Survival analyses were performed using the Kaplan-Meier method and the Cox regression model. To analyze the role of Skp2 in vitro, NSCLC cells were transfected with an Skp2-expressing vector or small interfering RNA. RESULTS: Skp2 was overexpressed in males, smokers, patients with squamous cell carcinomas, and patients with poorly differentiated cancers (P = .034, < .0001, < .0001, and .002, respectively). The multivariant analysis revealed that Skp2 expression is an independent prognostic factor for survival in NSCLC. An inverse relationship of Skp2 with p27 expression was observed (P = .012), and patients with both a higher expression of Skp2 and a lower expression of p27 showed a significantly unfavorable prognosis (P = .0002). In vitro ectopic expression of Skp2 in NSCLC cells reduced the protein level of p27. Conversely, induction of Skp2 siRNA increased the protein level of p27, leading to growth inhibition in NSCLC cells. CONCLUSION: Skp2 overexpression is closely associated with the suppression of p27 and the aggressiveness in NSCLC. It also could be a therapeutic target in NSCLC.     

Postoperative enteroparesis by patient-controlled analgesia combined with continuous epidural block for patients after posterior lumbar surgery

This study evaluated postoperative enteroparesis influenced by patient-controlled analgesia combined with continuous epidural block in patients who underwent posterior lumbar surgery. One hundred nine patients were divided into three groups at random (group 1, controls (18 patients); group 2, postoperative patient-controlled analgesia and continuous epidural block (45 patients); group 3, one-shot epidural analgesia, postoperative patient-controlled analgesia, and continuous epidural block (46 patients). The patients in groups 2 and 3 had more satisfactory pain relief and needed analgesics less frequently. However, their clinical abdominal findings the morning after surgery were worse than those in control patients. The times when patients could take any nourishment and eat solid food (rice) were delayed by patient-controlled analgesia with continuous epidural block.
