Vitiligo is a chronic disorder of depigmentation that has different treatment modalities, butpatients’ nonadherence is common. This study aimed to assess the influence of patients’ medication beliefs on patients’ adherence to topical, oral medications, and phototherapy in vitiligo. Between September 2015 and February 2016, 260 patients with vitiligo were asked to fill in theBeliefs about Medicines Questionnaire (BMQ) to assess their beliefs about therapy for vitiligo.Their adherence to the therapy was examined using the 8-item Morisky Medication Adherence Scale (MMAS-8). Results: The MMAS-8 scale and BMQ had good internal consistency (Cronbach’s a 50.78 and 0.66, respectively). Using Morisky’s recommended cutoff point, 71% of patients were categorized as low or nonadherent to the scheduled therapy. Patients who perceived specific necessity of dermatological medicines significantly adhered to their therapy (OR 1.23; 95% CI 1.09, 1.38; p = 0.001) whereas patients who had specific concerns about the adverse effects exhibited significant low adherence (OR 0.65; 95% CI 0.56, 0.76; p0.001). Conclusion: Positive beliefs about the necessity of medications in vitiligo do not necessarily reflect high adherence. Patients’ adherence behavior is a multidimensional and dynamic process. The prolonged course of treatment, its cost, and unsatisfactory outcomes influenced the patients’ adherence.

Background: Cardiovascular medications have been commonly associated with medication errors. Objective: The objective of this study was to investigate the incidence and predictors of medication errors in patients with acute coronary syndrome. Setting: the coronary care unit of a university teaching hospital. Methods: This was a prospective observational study on 150 patients admitted to the coronary care unit between August 2014 and July 2015. Main outcome measure: The principal outcome was the number (frequency) of encountered medication errors. Results: Of total 5790 prescription items reviewed, 547 (9.4%) potential medication errors were identified of which 523 (9.0%) were prescribing errors and 24 were monitoring errors. The most frequent prescribing errors were dosing errors (231, 42.2%) followed by loading dose omission error (91, 16.6%), omission of essential drugs on 1st day(43, 7.9%), and timing error (40, 7.3%). Errors frequently encountered with drugs such as aspirin, enoxaparin, beta-blockers followed by angiotensin-converting enzyme inhibitors and clopidogrel. Multivariate logistic regression analysis revealed that renal impairment (OR 6.02; 95% CI1.4–35.4; p = 0.02) and longer duration of hospital stay (OR 4.01; 95% CI 1.5–10.7; p = 0.005) were predictors of the higher incidence of medication errors. Conclusion: Prescribing and monitoring errors in coronary care unit are frequent and avoidable, with the majority of errors were ranked to be of mild to moderate severity. Dosing errors, omission of essential drugs and monitoring errors were most common error types encountered. Dosage adjustment based on estimation of the glomerular filtration rate immediately after admission help avoiding dosage-related errors.

We are concerned with the development of novel anti-infectives with dual antibacterial and antiretroviral activities for MRSA/HIV-1 co-infection. To achieve this goal, we exploited for the first time the mechanistic function similarity between the bacterial RNA polymerase (RNAP) “switch region” and the viral non-nucleoside reverse transcriptase inhibitor (NNRTI) binding site. Starting from our previously discovered RNAP inhibitors, we managed to develop potent RT inhibitors effective against several resistant HIV-1 strains with maintained or enhanced RNAP inhibitory properties following a structure-based design approach. A quantitative structure–activity relationship (QSAR) analysis revealed distinct molecular features necessary for RT inhibition. Furthermore, mode of action (MoA) studies revealed that these compounds inhibit RT noncompetitively, through a new mechanism via closing of the RT clamp. In addition, the novel RNAP/RT inhibitors are characterized by a potent antibacterial activity against S. aureus and in cellulo antiretroviral activity against NNRTI-resistant strains. In HeLa and HEK 293 cells, the compounds showed only marginal cytotoxicity.

Methylxanthines especially theophylline have been recognized as potent bronchodilators for the relief of acute asthma for over 65 years. Recently, it was found that bacterial infection plays a role in asthma pathogenesis. Accordingly, the present work involves the synthesis of 6-(4-(un)substituted phenyl)thiazolo[2,3-f]theophyllines 2a-g and different series of 8-(1,2,4-triazol-3- ylmethylthio)theophyllines 6-9. The chemical structures of the target compounds were proved by IR, 1H NMR, 13C NMR, EI-MS and HRMS spectroscopic techniques along with elemental analyses. The bronchodilator activity of fifteen compounds was determined in vivo by acetylcholine induced bronchospasm in anaesthetized guinea pigs. Results revealed that all compounds showed moderate to good activity; in addition, five compounds exhibited a bronchodilator activity nearly similar to that of aminophylline as a standard. The antibacterial activity of all the target compounds was investigated in vitro against both Gram-positive and Gram-negative bacterial strains. Results revealed that some compounds showed more potent antibacterial activity than ampicillin as a standard. Acute toxicity study for four target compounds revealed that none of these derivatives showed significant toxicity up to 300 mg/kg. It was found that compound 8c combined both promising bronchodilator and antibacterial activities. This compound could be subjected for further investigations as a new possible candidate in the treatment of bronchial asthma.
