Tacrolimus interaction with oral oestrogen in kidney transplant recipients: A case-control study.

WHAT IS KNOWN AND OBJECTIVE: Oestrogens could inhibit the metabolism of drugs, such as calcineurin inhibitors, that are substrates for cytochrome P-450 microsomal enzymes. This study assessed the potential tacrolimus interaction with oral conjugated oestrogen in kidney transplant recipients who received conjugated oestrogen as prophylaxis against bleeding, before kidney biopsy. METHODS: In this case-control study, 13 kidney transplant recipients who received oral conjugated oestrogen as prophylaxis against uraemic bleeding before allograft biopsy were considered as cases. Thirteen matched kidney transplant recipients with similar immunosuppressive regimen served as controls. In this study, comparisons were made between the groups regarding daily dose, blood trough concentrations and calculated concentration corrected for dose of tacrolimus at three time points of the study. RESULTS AND DISCUSSION: All patients in the case group received conjugated oestrogen at a dose of 3.75 mg/day for 4.78 ± 0.83 days. Without any change in tacrolimus dose, the blood concentration of tacrolimus increased during concomitant administration of conjugated oestrogen (from 8.10 ± 2.85 to 12.35 ± 4.62 ng/mL; P = .11) and decreased after cessation of conjugated oestrogen (6.07 ± 2.18 ng/mL; P = .015). The calculated concentration corrected for dose of tacrolimus increased from 127.04 ± 79.23 to 211.40 ± 146.38 ngmLmgkg/d after conjugated oestrogen administration (P = .036). Thereafter, it decreased to 108.55 ± 78.61 ngmLmgkg/d after cessation of oestrogen (P = .003). Only one patient experienced nausea while taking oestrogen without any change in her liver enzymes. WHAT IS NEW AND CONCLUSION: Concomitant administration of oral oestrogen increased tacrolimus blood concentration. Hence, it is necessary to monitor tacrolimus blood levels during concomitant oestrogen therapy and for several days after oestrogen withdrawal.

Protecting impact of Jaft against carbendazim induced biochemical changes in male Wistar rats.

Introduction: Pesticides are a critical tool for crop protection and control of different pests and insects. The present research conducted to evaluate the protective role of Jaft extract against oxidative pressure, biochemical variations because of limited time giveaway to carbendazim in Wistar mice males. Fresh fruits of quercus brantii were dried and the internal layer (Jaft) was collected for a hydroalcoholic extract by a maceration method at normal ambient condition. For the experimental study, twenty-four adult male rats (Wistar albino rats weighing 150-200 g) were randomized into 3 teams out of eight. Team I subserved like a vehicle treated group, received corn oil additionally to their food, while the animals in the second team got 0.1 ml carbendazim (50mg/ kg in corn oil) via oral path for nine days. Rats in group III received Jaft (500 mg/ kg orally + in carbendazim for 9 days. Blood samples were obtained by heart puncture to determine alkaline phosphatase (ALP), blood urea nitrogen (BUN), creatinine, alanine (ALT) and aspartate aminotransferases (AST); by using auto-analyzer in serum.Kidneys and liver separated from rats and provided for series of biochemical parameters homogenization like GSH and MDA stages. Result: The serum content of AST, ALT, ALP, BUN and creatinine were significantly elevated by in carbendazim treatment (group II) compared to the negative group (p<0.01).The liver enzymes operations, creatinine and BUN were significantly reduced in rats (p<0.05) when Jaft was received in a short period of time (group III). Hepatic and GSH and renal MDA stages in group (II) were clearly (p<0.05) enhanced and decreased consequently. The GSH and MDA stages content were significantly normalized in mice (p<0.05) when Jaft was received by group III. Conclusions: According to the present data, Jaft can neutralize carbendazim contain pressure of oxidative and recover the abnormal pathological injuries in Wistar mice males.

Health research barriers in the faculties of two medical institutions in India.

BACKGROUND: Health policy formation refers to the design of a conceptual framework to find possibilities, facilitate feasibilities, and identify strong and weak points, as well as insufficiencies, by research. Doing research should clarify qualities and standards for policy and decision-making to enable the success of development of health care in a country. Evaluation of the impact of health interventions is particularly poorly represented in public health research. This study attempted to identify barriers and facilitators of health research among faculty members in two major institutions in India, ie, the All India Institute of Medical Sciences (AIIMS) and the University College of Medical Sciences (UCMS) and Guru Tegh Bahadur (GTB) Hospital in Delhi. METHODS: The participants were asked to fill in a questionnaire that canvassed individual characteristics, ie, years of experience, place of work, academic rank, final educational qualification, work setting, educational group, primary activity, and number of publications in the previous 5 years. Barriers and facilitators were categorized into personal, resources, access, and administration groups. The data were processed using SPSS version 16, independent t-tests, Chi-square tests, and multivariate logistic regression. RESULTS: The total number of faculty members at both institutions was 599, 456 (76%) of whom participated in this study. The primary activities reported by faculty at UCMS (teaching) and Faculty at AIIMS reported (Research and Provision of health care services) as a major activity (P < 0.01). The majority of faculty members at UCMS and GTB Hospital were professors, whereas most of the faculty members at AIIMS were associate professors (P < 0.01). Of 47 barriers and facilitating factors, there were 26 barriers and 21 facilitating factors at AIIMS and 39 barriers and eight facilitating factors at UCMS. Faculty members at UCMS had 6.572 times more barriers to health research than those at AIIMS. CONCLUSION: Close proximity between AIIMS and the Indian Council of Medical Research and the National Medical Library, housing, transport, and a good reference library with an adequate knowledge support system provided suitable opportunities for faculty members at AIIMS to do research. To overcome the barriers, institutions must have enough financial support, decreased nonessential clinical, laboratory, and service schedule duties on the part of faculty members, preparation of good and relevant statistical courses and workshops, and access to good statistical software packages.

Anemia and iron deficiency in adolescent school girls in kavar urban area, southern iran.

BACKGROUND: Anemia is one of the most common public health problems especially in developing countries. We investigated the prevalence of anemia, iron deficiency anemia and related risk factors in adolescent school girls in Kavar urban area in southern Iran. METHODS: A total of 363 adolescent school girls were evaluated by a cross sectional study. Socioeconomic, demographic and related risk factors were obtained by a questionnaire. Hematological parameters and serum iron indices were measured. RESULTS: There were 21 cases of anemia (5.8%), 31 (8.5%) iron deficiency and 6 (1.7%) iron deficiency anemia.  Most of anemic girls (85.7%) had mild anemia.  MCV, TIBC, age, and BMI had statistically significant relationship with hemoglobin. Only parasites infestation in the last three months had a 6.83 times more risk of anemia than those without this history (95% CI, 1.66-28.11). CONCLUSION: The prevalence of anemia and iron deficiency anemia in this study were substantially less than what reported in many other regions of Iran as well as other developing countries. It seems that related implemented strategies in the recent years have been successful. More especial attention to prevention of parasite infestation should be considered in this area.

Endoscopic ultrasound-guided fine-needle aspiration for the diagnosis of solid pancreatic masses: the impact on patient-management strategy.

BACKGROUND: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is a safe and accurate technique for diagnosing pancreatic cancer. However, its impact for management of these patients is poorly investigated. AIMS: To investigate the diagnostic yield and the therapeutic impact of EUS-FNA in the management of solid pancreatic masses. METHODS: One hundred consecutive patients who underwent EUS-FNA for a solid pancreatic mass were included. Aspirates were placed onto glass slides for cytological examination and microbiopsies were fixed in formaldehyde for histology. The impact on clinical management was analysed retrospectively according to different endpoints, such as its impact on indications for chemotherapy, surgery or appropriate follow-up modality. RESULTS: Eight procedures were considered failures and two patients were lost to follow-up. A final diagnosis was obtained in 90 patients. The sensitivity, specificity and accuracy of combined cytology and histology for the diagnosis of malignant or potentially-malignant tumours were 78%, 75%, and 78% respectively. The sensitivity and accuracy of cytology alone were significantly higher than those of histology alone (P = 0.0003). By intention-to-diagnose analysis, EUS-FNA directly influenced the management strategy in 62 of 100 patients. CONCLUSIONS: In patients with pancreatic mass and suspected malignancy, EUS-FNA provides an accurate diagnosis in approximately 80% of cases. EUS-FNA directly influences the management in two-thirds of patients.

[Vacuum-Assisted Closure in the treatment of a large thoracic defect with Gore Tex prosthesis exposure: a case report]. / Utilisation du Vaccum-Assisted Closure pour la reconstruction d'une perte de substance thoracique transfixiante avec exposition d'une plaque en Gore Tex: à propos d'un cas.

Vacuum-Assisted Closure (VAC) technique has been used in the treatment of acute and chronic wounds. The authors report a case of large thoracic defect, where the VAC was used to cover an exposed Gore Tex prosthesis after the failure of a latissimus dorsi flap. The VAC managed to save the Gore Tex prosthesis before a delayed reconstruction.

[The value of sialo-MRI in the study of salivary gland duct pathology]. / Intérêt de la sialo-IRM dans l'exploration des pathologies canalaires des glandes salivaires.

Usual imaging diagnostic for salivary glands is sialography. Sialography is not stripped of disadvantages and failures. The MRI-sialography is an examination which is carried out without any injection of contrast's product (without catheterization or intravenous injection). It is thus noninvasive and painless. The complete study of salivary gland and its ducts is always possible and could not be blocked by local or loco-regional conditions. It allows exploration of several salivary glands in the same time. We think that the MRI-sialography must find its place in the diagnosis arsenal for salivary pathology in spite of its current handicaps represented by its cost and the difficulty of access to the apparatuses.
