Equipercentile linking of the BPRS and the PANSS.

The Positive and Negative Syndrome Scale (PANSS) and the Brief Psychiatric Rating Scale (BPRS) are the most frequently used scales to rate the symptoms of schizophrenia. There are many situations in which it is important to know what a given total score or a percent reduction from baseline score of one scale means in terms of the other scale. We used the equipercentile linking method to identify corresponding scores of simultaneous BPRS and PANSS ratings in 3767 patients from antipsychotic drug trials. Data were collected at baseline and at weeks 1, 2, 4 and 6. BPRS total scores of 18, 30, 40 and 50 roughly corresponded to PANSS total scores of 31, 55, 73 and 90, respectively. An absolute BPRS improvement of 10, 20, 30, 40 points corresponded to a PANSS improvement of 15, 32, 50, and 67. A percentage improvement of the BPRS total score from baseline of 19%, 30%, 40% and 50% roughly corresponded to percentage PANSS improvement of 16%, 25%, 35%, and 44%. Thus a given PANSS percent improvement was always lower than the corresponding BPRS percent improvement, on the average by 4-5%. A reason may be the higher number of items used in the PANSS. These results are important for the comparison of trials that used these rating scales. We present a detailed conversion table in an online supplement.

[Treatment for overactive bladder]. / Therapie der überaktiven Blase.

BACKGROUND: Epidemiological data demonstrate an increasing prevalence of symptoms of overactive bladder (OAB) with age not only in women, but especially in men. Despite a comparable prevalence, however, men are still highly underrepresented in most large randomized studies on the effect of antimuscarinic drugs. QUESTION: In this subgroup analysis of the CAP Study the efficacy and tolerability of solifenacin was examined in 111 men with symptoms of OAB. The study was performed in a network between general practitioners and urologists under routine conditions over a period of 12 months. RESULTS: Treatment with solifenacin reduced all symptoms of OAB significantly, and the use of pads decreased by more than half. The tolerability of therapy was judged as "excellent" or "good" by over 95% of doctors and patients. CONCLUSION: This subgroup analysis of the CAP Study confirms the good efficacy and tolerability of solifenacin in male OAB in daily practice over a treatment period of 1 year.

Tenascin and aggrecan expression by articular chondrocytes is influenced by interleukin 1beta: a possible explanation for the changes in matrix synthesis during osteoarthritis.

OBJECTIVE: To analyse the distribution patterns of tenascin and proteoglycans in normal and osteoarthritic cartilage, and to determine the effect of interleukin 1beta (IL1beta) on aggrecan and tenascin expression by human articular chondrocytes in vitro. METHODS: Normal and osteoarthritic cartilage and bone samples were obtained during total knee replacements or necropsies. After fixation and decalcification, paraffin embedded specimens were sectioned perpendicular to the surface. Specimens were graded according to Mankin and subdivided into those with normal, and mild, moderate, and severe osteoarthritic lesions. Serial sections were immunostained for tenascin. Tenascin expression by healthy and osteoarthritic chondrocytes was quantified by real time polymerase chain reaction (PCR). Furthermore, in cell culture experiments, human articular chondrocytes were treated with 0.1 or 10 ng/ml IL1beta. Real time PCR analyses of aggrecan and tenascin transcripts (normalised 18S rRNA) were conducted to determine the effect of IL1beta on later mRNA levels. RESULTS: Tenascin was immunodetected in normal and osteoarthritic cartilage. In osteoarthritic cartilage increased tenascin staining was found. Tenascin was found specifically in upper OA cartilage showing a strong reduction of proteoglycans. Greatly increased tenascin transcript levels were detected in osteoarthritic cartilage compared with healthy articular cartilage. IL1beta treatment of articular chondrocytes in vitro significantly increased tenascin transcripts (approximately 200% of control) and strongly reduced aggrecan mRNA levels (approximately 42% of control). CONCLUSIONS: During progression of osteoarthritis the switch in matrix synthesis occurs mainly in upper osteoarthritic cartilage. Furthermore, changes in synthesis patterns of osteoarthritic chondrocytes may be significantly influenced by IL1beta, probably diffusing from the joint cavity within the upper osteoarthritic cartilage.

Finasteride and flutamide as potency-sparing androgen-ablative therapy for advanced adenocarcinoma of the prostate.

OBJECTIVES: Androgen ablation with luteinizing hormone-releasing hormone (LHRH) agonists, orchiectomy, or oral estrogens has significant untoward sexual side effects. We evaluated a combination of finasteride and flutamide as potency-sparing androgen ablative therapy (AAT) for advanced adenocarcinoma of the prostate. In addition, we evaluated whether finasteride provided additional intraprostatic androgen blockade to flutamide. METHODS: Twenty men with advanced prostate cancer were given flutamide, 250 mg orally three times daily. Serum prostate-specific antigen (PSA) values were measured weekly. At a nadir PSA value, finasteride, 5 mg orally every day, was added. PSA values were then measured weekly until a second nadir PSA value was achieved. Sexual function was evaluated at baseline, at the second nadir PSA value, and every 3 months thereafter. Testosterone, dihydrotestosterone (DHT), and dehydroepiandrostenedione (DHEA) levels were measured at baseline and at the first and second nadir PSA values. RESULTS: The median follow-up period was 16.9 months. Therapy failed in 1 patient with Stage D2 disease at 12 months, but an additional response to subsequent LHRH agonist therapy was observed. One patient developed National Cancer Institute grade 3 diarrhea and was withdrawn from the study. Seven of 20 men developed mild gynecomastia, and 3 of 20 developed mild transient liver function test elevations. Mean PSA levels were 94.6 +/- 38.2 ng/mL at baseline and 7.8 +/- 2.7 and 4.7 +/- 2.2 ng/mL at the first and second PSA nadir values, respectively (P = 0.034). Mean percent decline in PSA value from baseline was 87.0 +/- 3.1% with flutamide alone and 94.0 +/- 1.9% with both flutamide and finasteride (P = 0.001). Eleven of 20 men were potent at baseline. At the second nadir PSA value, 9 (82%) of 11 were potent, whereas 2 (18%) of 11 were impotent. With longer follow-up (median 16.4 months), 6 (55%) of 11 men were potent, 2 (18%) of 11 were partially potent, and 3 (27%) of 11 were impotent. With flutamide alone, testosterone rose a mean of 77 +/- 14.7% of baseline (P = 0.0001), DHEA fell a mean of 32.4 +/- 4.6% (P = 0.0001), and DHT was unchanged. With the addition of finasteride, testosterone rose another 14 +/- 6% (P = 0.06, not significant), DHEA was unchanged, and DHT fell a mean of 34.8 +/- 4.7% (P = 0.0009). CONCLUSIONS: Finasteride and flutamide were safe and well tolerated as AAT for advanced prostate cancer. Finasteride provided additional intraprostatic androgen blockade to flutamide, as measured by additional PSA suppression. Sexual potency was preserved initially in most patients, although there was a reduction in potency and libido in some patients on longer follow-up. Further evaluation of this therapy is needed.

Post-hospital sub-acute care: an example of a managed care model.

OBJECTIVE: This article describes Transitional Care Centers (TCC), an innovative sub-acute care program developed by a large managed care organization (HealthPartners in Minnesota) in partnership with five area nursing homes. The purpose of the TCC is to promote continuity of care for frail older members covered under a TEFRA risk contract. DESIGN: This is a retrospective study of the experiences and outcomes of enrollees who received TCC compared with a like group of enrollees who received customary continuity care through contract services. SETTING: The TCCs are established contractually in five area nursing homes; these facilities keep at least 15 beds available to the health plan for round-the-clock, 7 days per week admissions for sub-acute care. Designated staff from these facilities and designated geriatric nurse practitioners and geriatricians from HealthPartners follow established targeting, admissions, assessment, care planning, and discharge planning procedures to provide team care for these patients at the facilities. PARTICIPANTS: The TCC program is targeted to patients requiring rehabilitation therapy (post-cardiovascular accident, post-fracture/replacement) who are deconditioned, or those with uncomplicated infections (urinary tract infection, pneumonia). A total of 1144 patients participated in the TCC program in the 1-year program under report, and 253 were surveyed in regard to their experience. One hundred HealthPartners physicians were surveyed about the program. RESULTS: Post-acute length of stay in the TCC was substantially lower than that in customary care settings in contract nursing homes (14.3 versus 20.5 days). Rehospitalization rates from these units were comparable to or better than those from other sub-acute units. Patient and primary care physician satisfaction with the units was high. The program provided economic benefit to both partners. The health plan's negotiated rate for the TCC units was 38% less than that paid in noncontractual facilities. CONCLUSION: The TCC partnership provides rehabilitative and geriatric evaluation services in settings more conducive to and less costly than such care usually, and yields improvements in care and utilization outcomes.

[Priapism--erectile potency following conservative and surgical treatment]. / Priapismus--die erektile Potenz nach konservativer und operativer Behandlung.

Priapism is a rare urologic disease, which is characterized by a pathological, increasingly painful permanent erection of the penis, is appearing without sexual sensations and does not recede spontaneously. The cavernous bodies are affected, not, however, the corpus spongiosum penis and the glans penis. A permanent loss of the erection caused by fibrosation of the trabeculae in the corpora cavernosa is the main complication of the disease. At the instance of 16 cases of the disease conservative and operative methods of therapy are discussed and described as method of choice the cavernosoglandular shunt of puncture after Ebbehøj/Winter is described. It is referred to the prognostic significance of an early, primarily operative treatment.

Ratite eggshells from lanzarote, canary islands.

Struthious and aepyornithoid eggshells from Tertiary calcareous sediments on Lanzarote prove the presence, until about 12 million years ago, of large flightless birds. The calcarenite horizon is recognized as an old land surface. Mesozoic sedimentary rocks in the basement of the volcanic islands of Lanzarote and neighboring Fuerteventura indicate that at least part of the Canary Archipelago is underlain by continental crust. Separation of the eastern Canaries from Africa raight have been by rifting, and a land connection might still have existed in the lower Pliocene.
