Evaluation of albendazole efficiency and complications in patients with pulmonary hydatid cyst

 Open in a separate windowOBJECTIVESThis study investigated the efficacy and complications of albendazole use after surgery in patients with pulmonary hydatid cysts.METHODSOne hundred fifty-three consecutive patients who met the study criteria out of 215 patients who received prophylaxis with albendazole after surgery for isolated pulmonary hydatid cysts in our clinic between January 2011 and December 2020 were analysed retrospectively.RESULTSEighty-six out of 153 (56.2%) of cases were male and 67 (43.8%) were female. The average age was 24.6 ± 17.4 (between 3 and 71 years), 76 of them (49.7%) were 18 years old and younger, while 77 (50.3%) were adults. All cases were approached transthoracically and a total of 170 operations were performed on the 153 cases. Fever, weakness and dizziness were reported in only one patient who was given albendazole treatment. A partial increase in liver enzymes was observed in 16 cases (10.5%) after albendazole treatment. Mild leukopoenia and neutropenia were observed in only one of the cases. In 1 case, a second operation was performed 30 months later due to recurrence. Albendazole treatment was not required to be discontinued in any of the cases. Mortality was not observed in any of the cases. Factors such as mean age, cyst size and hospitalization period did not have a statistically significant effect on any changes in liver enzymes tests following albendazole therapy (P > 0.05).CONCLUSIONSAlbendazole treatment can safely be used for postoperative prophylaxis in patients with pulmonary hydatid cysts in a controlled manner without causing serious complications.Subj collection152.     

Effectiveness and safety of elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate single-tablet combination among HIV-infected patients in Turkey: results from a real world setting

BackgroundEfficacy of elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil (E/C/F/TDF) in treatment-naïve and experienced patients with HIV infection was demonstrated in phase 3 trials. The primary objective of this study was to evaluate effectiveness and safety of E/C/F/TDF in real world settings.MethodsRetrospective, observational data collected by the Turkish ACTHIV-IST study group between May 2015 and December 2016 were analysed.ResultsA total of 387 patients were prescribed E/C/F/TDF; 210 patients with available data at 6th month were eligible; 91.5% were male, and mean age was 35.2 (SD: 10.8) years; 54.0% of males identified themselves as MSM. Sixty-three percent (133) of the study population were treatment-naïve patients, and 37% (77) were treatment experienced. HIV RNA level was below 100 copies/mL in 78.9% of treatment-naïve patients and 89.9% of treatment experienced patients at month 6. Median increase in CD4 T lymphocyte count was 218 copies/mL in treatment-naïve patients and remained stable or increased in treatment experienced patients. Adverse events were observed in 15% of the patients, and the regimen was discontinued in only six patients.ConclusionReal world data on the effectiveness and safety of E/C/F/TDF is comparable with the phase 3 trial results Adverse events are uncommon and manageable.     

Apport de la simulation dans l'apprentissage de l'examen du fond d'œil.

Introduction: Simulation is emerging as an essential part of health sciences training programs as it provides safer patient care by reducing the risk of error. In the healthcare environment, simulation continues to spread in emergency specialties, but it is still underdeveloped in ophthalmology and there is a shortage of publications on this subject in Tunisia. Objective: To evaluate the effectiveness of procedural simulation as a teaching tool for funduscopic examination training. Methods and population studied: This was a prospective study including students who underwent procedural simulation training sessions during their ophthalmology internship. The included students were assessed at the initiation and end of each session by a pre-test and post-test. The procedure for performing the funduscopic examination was evaluated by a specific performance score. Student satisfaction was assessed at the end of each session. Results: During the study period, four groups of 12 students were included, for a total of 48 participants spread over 4 simulation sessions. Simulation training improved post-test. assessment scores with an overall median delta of +4.00. It also provided specific skills for performing the funduscopic examination, with an overall median specific performance score of 5.5/8 (5/8 to 7/8). The majority of students were satisfied upon completion of the simulation session. Conclusion: The training of fundus examination using an ophthalmoscopic simulator can improve the skills and knowledge of ophthalmic learners. This type of training can be an innovative addition to traditional learning. methods.     

Investigation of Dynamic Thiol/Disulfide Homeostasis and Nitrosative Stress in Patients with Wilson Disease

Background: Wilson disease (WD) is an autosomal recessive inherited disorder of copper (Cu²⁺) metabolism, resulting in Cu²⁺ accumulation and liver and central nervous system toxicity. Oxidative stress may have a role in the pathogenesis of Wilson disease, but the roles of thiol/disulfide homeostasis and nitrosative stress have not been examined. The purpose of this study was to evaluate whether there is a modification in thiol/disulfide homeostasis and nitrosative stress in patients with Wilson disease.Methods: A total of 50 patients with Wilson disease (42 under drug treatment and 8 newly diagnosed patients with no drug treatment) and 50 healthy gender- and age-matched controls were enrolled for this study. Serum native thiol and total thiol levels were measured with a spectrophotometric method. The number of disulfide bonds and the related ratios were determined from these measurements. Serum nitric oxide (NO) and 3-nitrotyrosine (3-NT) levels were analyzed using chemiluminescence and ELISA assays, respectively.Results: The average native thiol levels of the patient group under drug treatment were found to be markedly higher than the levels of controls (P < .05). We detected no marked changes in total thiol and disulfide levels, and disulfide/total thiol, disulfide/native thiol, or native thiol/total thiol ratios between groups. We found significant elevations in NO levels in Wilson disease group before drug treatment, and the 3-NT levels in the Wilson disease groups prior to (P < .05) and under drug treatment (P < .01), when compared to controls.Conclusion: Our data are the first to show that nitrosative stress and thiol/disulfide homeostasis can contribute to the pathogenesis of Wilson disease.     

Corrective Effect of Verbascoside on Histomorphological Differences and Oxidative Stress in Colon Mucosa of Rats in Which Colon Ischemia–Reperfusion Injury was Induced

BackgroundThis study aims to show the corrective effect of verbascoside on histomorphological and biochemical differences in the colon mucosa of rats in which colon ischemia–reperfusion (I/R) injury was induced.Methods: Fifty Sprague Dawley male rats were divided into 5 groups, of control, sham, ischemia (I), I/R, and I/R+verbascoside.Ischemia and reperfusion were applied to the suitable groups for 30 minutes and 120 minutes respectively, and 10 mg/kg verbascoside was administered intraperitoneally. Histomorphological assessment was done in the colon tissues obtained, and the goblet cells were assessed using the Alcian blue method. Proliferating cell nuclear antigen (PCNA), TUNEL, and hypoxia-induced factor 1 (HIF-1α) assays were used to assess oxidative stress with the immunohistochemical method. Malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), and total thiol (TT) levels were checked, for a biochemical analysis of oxidative stress.Results: Compared with the I/R group, histomorphological differences were seen to be corrected in colon epithelium in the I/R+verbascoside group. The goblet cell number increased and cell proliferation was increased, as seen with the PCNA assay; and apoptosis was decreased, as seen with the TUNEL assay. HIF-1α expression also decreased in the drug group. In the drug group, SOD, GSH-Px, TAS, and TT levels increased, but TOS, OSI, and MDA levels decreased.Conclusion: It was seen that verbascoside had a corrective effect on histomorphological and biochemical differences caused by I/R injury.     

The effects of isotretinoin therapy on the biliary system

The aim of the present study was to investigate the potential effects of isotretinoin on the biliary system in patients with acne vulgaris receiving isotretinoin therapy. This was a preliminary retrospective study involving 40 patients with severe acne vulgaris who attended the dermatology clinic and were administered different doses (20 or 30 mg/day) of isotretinoin. Serum levels of AST, ALT, ALP, GGT, total bilirubin, direct bilirubin, and indirect bilirubin at the beginning and at the first month of therapy were scanned, recorded, and statistically analyzed. Total and indirect bilirubin levels at the first month of treatment in 30 patients, receiving isotretinoin at a dose of 20 mg/day, were significantly lower compared to the baseline values (p = .02 and p = .03, respectively), whereas AST and GGT serum levels were significantly higher (p = .003 and p = .006 respectively). No significant reduction in total and indirect bilirubin levels was detectable at the first month of treatment in 10 patients receiving isotretinoin at a dose of 30 mg/day; however, AST, ALP, and GGT levels were significantly elevated in these patients (p = .023; p = .004; and p = .001, respectively). To our knowledge, there is no previous study investigating the effects of isotretinoin on the biliary system, and, therefore, the present study is a preliminary one. Our findings implicate that low dose (20 mg/day) isotretinoin therapy can potentially reduce total and indirect bilirubin levels. Long‐term, large‐scale, prospective studies with patients receiving different doses of isotretinoin may provide more reliable information regarding the bilirubin lowering effects of isotretinoin and optimum dosing for achieving this clinical effect.     

Intralesional zinc sulfate 2% vs intralesional vitamin D in plantar warts: A clinicodermoscopic study

Verrucae are benign proliferations seen in skin due to infection with papillomaviruses. There are different treatment strategies for warts but all of these treatments are painful, time consuming, expensive, and recurrence is common. To evaluate and compare the efficacy of intralesional 2% zinc sulfate solution vs vitamin D3 in the treatment of plantar warts, as well as reporting the side effects. This three‐armed randomized clinical trial included 105 patients presented with plantar warts divided into three groups, 35 patients per group. The first group received intralesional 2% zinc sulfate, the second group received intralesional 2% vitamin D3, and the third group received normal saline. Four sessions were done, one every 2 weeks. At the end of the study, patients showing complete response were more in zinc group (71.4%), vitamin D3 group (62.9%) compared to saline group (40%). Most of the patients in zinc group showed severe pain during injection (48.6%), most of the patients in vitamin D3 group showed mild pain (80%), while most of the patients in saline group showed no pain (57.1%). Both intralesional 2% zinc sulfate and vitamin D3 are effective in treatment of plantar warts, with zinc sulfate being more effective.
