Age at onset, childhood psychopathology, and 2-year outcome in psychotic bipolar disorder

OBJECTIVE: The relationships of age at onset and childhood psychopathology to 2-year clinical and functional outcomes in first-admission patients with bipolar I disorder were examined. METHOD: Patients with bipolar I disorder (N=123) presenting with psychotic symptoms were followed over a 2-year period. Age at onset was stratified into <19 and >or=19 years. Childhood psychopathology was categorized as behavior problems, other psychopathology, and none. Functional and clinical outcomes were rated with standard measures. RESULTS: Childhood psychopathology and age at onset were independently related to poorer functional and clinical outcome. In the multivariate models that included psychopathology, age at onset, sex, and education, early age at onset was related to incomplete remission, and childhood psychopathology was related to functional outcome. CONCLUSIONS: Childhood psychopathology and age at onset contribute independently to outcomes of bipolar disorder. Childhood psychopathology is a much stronger predictor of functioning than age at onset.     

Evaluation of PCR-ELISA for determination of telomerase activity in prostate needle biopsy and prostatic fluid specimens

The conventional TRAP assay will determine telomerase activity in tissue or other specimens. However, methodological disadvantages limit its clinical use. We evaluated a modified TRAP assay, the telomerase PCR-ELISA, as a practical clinical system for measuring its activity in conjunction with prostate cancer (PCa). We examined telomerase activity by both TRAP and PCR-ELISA assays in 48 sextant needle biopsy (SNB) specimens from dye-marked areas of the prostate glands of 7 PCa patients. Each specimen was histologically confirmed as cancerous or cancer-free by examining a paired specimen taken from the same marked area. In addition, prostatic fluid (PF) specimens were analyzed from 18 patients, 9 of whom were diagnosed with PCa while 9 were diagnosed as cancer-free but mostly with BPH. The results on individual SNB specimens matched well for the two methods. The sensitivity (91%) and specificity (69%) for the PCR-ELISA measurements were consistent with those for the conventional TRAP assay, 88% and 81%, respectively. Quantitatively, with the PCR-ELISA assay, the mean telomerase activity (24.5+/-28.4 units) per needle core with PCa cells was significantly higher than that in needle cores without PCa cells (7.2+/-2.2 unit), as it was with the conventional TRAP assay, namely 25.6+/-27.8 units and 7.3+/-1.8 units, respectively. In PF specimens from PCa patients, which had a lower mean telomerase than was found in needle cores containing PCa cells (7.1+/-1.5 units in the PCR-ELISA, 7.2+/-1.8 units in the conventional TRAP assay), statistical analysis showed good matching between the results from the two assays, overall. In conclusion, the PCR-ELISA can be considered a reliable method to determine telomerase activity as an adjunct in the diagnosis and treatment of prostate cancer.     

Labor induction

Labor induction has become commonplace in modern obstetrics. The increasing rate of labor induction has probably played a role in the increased rate of cesarean delivery observed in the United States during the past few decades. Clearly, the favorability of the cervix has a substantial impact on the potential success of any labor induction. Induction in the setting of an unfavorable cervix can result in prolonged induction, prolonged hospitalization, failed induction, and an increased cesarean delivery rate. In this modern era of healthcare reform and cost containment, the identification of therapeutic strategies to enhance the success and cost-effectiveness of labor induction are of great interest. Ongoing research is needed to advance our knowledge of the mechanisms of parturition and cervical ripening in order to direct interventions for labor induction more effectively.     

Fetal but not adult Leydig cells are susceptible to adenoma formation in response to persistently high hCG level: a study on hCG overexpressing transgenic mice

We have previously demonstrated that male transgenic (TG) mice overexpressing human chorionic gonadotropin (hCG+) develop reproductive organ defects, but no tumors, in adult age. In this study, the effects of persistently elevated hCG were followed in TG males between day 5 postpartum and adulthood. Leydig cell (LC) adenomas were found in prepubertal mice, most prominently at the age of 10 days, but not in adult age. Serum testosterone concentrations were significantly increased in TG males at all ages studied. The phenotype of the prepubertal hCG+ males resembled that found in boys upon expression of constitutively activating luteinizing hormone (LH) receptor mutations. The temporal expression patterns of the fetal LC marker gene, thrombospondin 2, and those of adult LCs, hydroxysteroid dehydrogenase-6, delta5-3-beta and prostaglandin D synthase, were similar in wild-type and hCG+ males. Hence, the postnatal adenomas resemble functionally fetal LCs, and only these cells are susceptible to hCG-induced tumorigenesis. Our findings demonstrate a novel intriguing difference between the fetal and adult LC populations and provide further insight into the potential tumorigenic effects of gonadotropins.     

Classification of the external auditory canal cholesteatoma

OBJECTIVES/HYPOTHESIS: The external auditory canal cholesteatoma (EACC) is a rare disease in the field of otolaryngology. Only 1 in 1,000 new otologic patients present with this entity, which was first described by Toynbee. The aim of this article is to classify EACC by different histopathologic and clinical findings of patients presenting to the Department of Otolaryngology at the University of Mannheim, Germany. METHODS: From 2000 to 2004, 17 patients presented to our clinic with EACC. The cholesteatoma were treated surgically, and the specimens were investigated histologically. Clinical findings were also recorded. We classified four stages: stage I with hyperplasia of the canal epithelium, stage II including periosteitis, Stage III including a defective bony canal, and stage IV showing an erosion of adjacent anatomic structure. RESULTS: Eight patients presented with stage II, five patients with stage III, three with stage I, and only one patient presented with erosion of the mastoid cells, which was determined as stage IV. CONCLUSION: In summary, our classification serves to describe the different histopathologic and clinical stages of EACC.     

Service use and outcomes of first-admission patients with psychotic disorders in the Suffolk County Mental Health Project

OBJECTIVE: The purpose of the study was to examine the inpatient and outpatient service use and 4-year outcomes of newly admitted psychotic patients during a period of rapid change in the provision of psychiatric services in a well-defined catchment area in New York State in the 1990s. METHOD: Subjects were 573 participants of the Suffolk County Mental Health Project. This group comprised patients with psychotic disorders first admitted between September 1989 and August 1995 to 12 inpatient facilities across Suffolk County, N.Y., and followed for up to 48 months. The subjects' service use, course of illness, symptomatic outcomes, suicide risk, homelessness risk, and satisfaction with care were compared across admission years. RESULTS: The length of inpatient stays decreased significantly across the years. However, the number of outpatient visits and therapy sessions did not vary. Although the patients admitted in later years were more symptomatic at admission to their first hospitalization, their course and outcomes over the follow-up period were not worse and they were not less satisfied with their care, compared with the patients admitted in earlier years. CONCLUSIONS: The clinical characteristics of patients and the role of inpatient care in the management of patients with psychotic disorders gradually changed during the 1990s. These changes, however, were not associated with changes in the use of outpatient services or outcomes. Nevertheless, shorter hospital stays and the presence of more severely ill patients highlight the need for more attention to linkage to aftercare and enhancement of support networks in the community.
