Relationship of chronic pelvic pain to psychiatric diagnoses and childhood sexual abuse

Structured psychiatric and sexual abuse interviews were administered to 25 women with chronic pelvic pain and a comparison group of 30 women with specific gynecological conditions. All 55 patients underwent diagnostic laparoscopy, and the results of the fiberoptic pelvic examination were objectively classified by the study gynecologist, who was blind to the psychiatric diagnoses. The patients with chronic pelvic pain showed a significantly higher prevalence of major depression, substance abuse, adult sexual dysfunction, somatization, and history of childhood and adult sexual abuse than the comparison group. There were no significant differences between the groups in severity or type of pelvic pathology.     

Variations of lymphocyte sub-populations in vulvar condylomata during therapy with beta-interferon.

Several experiences induced us to consider genital HPV infection as an expression of a local immunodeficiency. The aim of our study was to research the effect of immunotherapy on the lymphocyte subpopulations and Langerhans cells in vulvar condyloma. Twenty women with persistent vulvar condylomata, treated with 2,000,000 IU/die of beta-interferon for 15 days, were submitted to vulvar biopsy before and 2-5 months after medical treatment. The frozen sections obtained were assayed with the following monoclonal antibodies: OKT 4 (T helper lymphocytes), OKT 8 (T suppressor lymphocytes), OKB 7 (B lymphocytes) and S-100 protein (Langerhans cells). Using a morphometric evaluation, the average number of both intraepithelial and stromal lymphocyte subsets and of the intraepithelial Langerhans cells was assessed. In all the biopsies preceeding the medical treatment we found a low number of T helper lymphocytes both in the epithelium and stroma, with inversion of T4/T8 lymphocyte ratio and rare presence of Langerhans cells. In patients with a good therapeutic response (50-100% of condyloma reduction) we observed an increase in intraepithelial T4 lymphocytes and a decrease in both intraepithelial and stromal T8 lymphocytes. In cases with persistent disease after therapy, the histological pattern was similar to that observed in the first biopsy, with the exception of a significant increase in the average number of Langerhans cells. Our data correlate the clinical response to the immunotherapy with the histology of lymphocyte subsets in the vulvar condylomata. The increase in Langerhans cells observed in patients with negative response may be interpreted with a probable inability of these cells to promote the immune reaction.     

Periocular involvement in cutaneous leishmaniasis

OBJECTIVE: Although cutaneous leishmaniasis (CL) occurs mostly in the facial area, periocular involvement accounts for 2-5% of the facial lesions. CL lesions localized in the periocular region can easily be confused with various other diseases. The aim of this study was to examine the frequency of periocular involvement in CL in the Cukurova region of Turkey, as well as the clinical characteristics, diagnosis and methods of treatment of this disease. METHODS: Between December 1998 and December 2004, patients who were diagnosed with CL were evaluated prospectively with respect to periocular involvement. RESULTS: From the 2066 patients evaluated with CL, 2622 lesions were identified. In 59 (2.9%) of these patients, a total of 66 (2.5%) lesions were located in the periocular area. Thirty-two (48.5%) of these lesions were of the papular type, 15 (22.7%) the nodulo-ulcerative type, 10 (15.2%) the plaque type, and nine (13.6%) the nodular type. Dacryocystitis was identified in four patients with periocular involvement. Over the follow-up period, no ocular or periocular deformities or complications developed in these patients. CONCLUSION: Patients suspected of CL should be evaluated and treated early in the course of their disease to prevent any permanent ocular or periocular deformities.     

Effects of the antimigraine compound zolmitriptan ('Zomig') on psychomotor performance alone and in combination with diazepam in healthy volunteers

Zolmitriptan (Zomig^TM) is a 5HT_1B/1D agonist which has the ability to cross the intact blood-brain barrier to access central as well as peripheral receptors. Because of the potential for central nervous system side effects, this randomized, double-blind, placebo-controlled, 6-period crossover study evaluated the effects of 2.5 and 5 mg doses of zolmitriptan on psychomotor performance and investigated any pharmacodynamic or pharmacokinetic interaction with diazepam. Twelve healthy volunteers received the following "treatments" as single doses: zolmitriptan 2.5 mg, zolmitriptan 5 mg, diazepam 10 mg, zolmitriptan 2.5 mg+diazepam 10 mg, zolmitriptan 5 mg+diazepam 10 mg and placebo. Pre-dose and at 1, 4, 8, and 24 h post-dose, the following validated battery of psychomotor tests was performed: Bond-Lader visual analogue scales (calmness, contentedness, and alertness factors), critical flicker fusion test, choice reaction time (recognition, motor, and total reaction times), finger-tapping test, number cancellation test and digit symbol substitution test. Plasma concentrations of zolmitriptan, its active metabolite, and diazepam and its active metabolites were measured at the same timepoints. Zolmitriptan 2.5 and 5 mg had no effect on psychomotor function when given alone. In contrast, diazepam 10 mg had profound effects, consistent with its sedative properties, but there was no synergism on concomitant administration of either dose of zolmitriptan. Plasma concentrations of zolmitriptan, diazepam, and their respective active metabolites were similar when the two drugs were given alone or in combination.
