Myocarditis complicating Plasmodium vivax malaria.

Myocarditis complicating Plasmodium vivax malaria is an extremely rare complication. We report this development in a young girl who was diagnosed to have P. vivax malaria on the basis of peripheral smear. While undergoing antimalarial treatment, she developed respiratory distress requiring invasive mechanical ventilation and inotropic support due to cardiogenic shock secondary to myocarditis. Cardiovascular complications are well recognized with Plasmodium falciparum malaria. Nevertheless, a high index of suspicion should be maintained for the same in Plasmodium vivax infection especially if symptoms of heart failure develop in a young patient

Cutaneous Ulcers as Initial Presentation of Localized Granulomatosis with Polyangiitis: A Case Report and Review of the Literature

Background. Granulomatosis with polyangiitis (GPA) is an ANCA associated small vessel vasculitis characterized by necrotizing granulomatous inflammation involving the upper and the lower respiratory tract and the kidneys. The disease has a broad clinical spectrum that ranges from limited/localized involvement of a single organ system to a generalized systemic vasculitis that affects several organs with evidence of end organ damage. Atypical forms of the disease have been recognized with or without respiratory tract involvement with a long protracted course before manifesting as generalized disease. Case Presentation. We describe a 57-year-old woman who presented with recurrent fever and cutaneous ulcers on her legs who was diagnosed to have granulomatosis with polyangiitis (GPA) after an extensive evaluation which excluded infectious, other vasculitides, connective tissue disease and malignant etiologies. Conclusion. In the absence of typical manifestations, granulomatosis with polyangiitis (GPA) is indeed a diagnostic challenge to the physician. Atypical manifestations like unexplained recurrent fever and cutaneous ulcers nevertheless call for keeping a low threshold for the diagnosis of GPA as the disease can initially present in localized form before heralding into a generalized disease

Bilateral Psoas Abscess After Extracorporeal Shock Wave Lithotripsy: Reminder Of A Rare Complication

Extracorporeal shock wave lithotripsy (ESWL) is among the most widely used modalities for treatment of urolithiasis since its introduction in the 1980s. The non-invasive technique reduces the risk of post-procedure complications and produces excellent stone free rates. However, complications may still follow and albeit rare, there are reports in literature of abscess formation post ESWL. Herein, we report the case of a young, immunocompetent gentleman who developed bilateral psoas abscess after undergoing this procedure. He was successfully managed at our institute with intravenous antibiotics, percutaneous abscess drainage and was discharged on day 5 post-intervention in a stable condition. There have been two similar cases reported in literature

Frequency of worsening liver function in severe dengue hepatitis patients receiving paracetamol: A retrospective analysis of hospital data.

Objective: To determine the frequency of worsening liver function among hospital in-patients with severe dengue hepatitis receiving paracetamol. Methods: This retrospective study was conducted at the Department of Medicine, Aga Khan University Hospital, Karachi, and comprised records of dengue patients with severe hepatitis who received paracetamol for control of fever between June 2007 and December 2014. Alanine aminotransferase at baseline and following paracetamol administration was noted, as well as dosage and duration of paracetamol, along with participants\u27 demographic details. Frequency of patients who developed worsening or improvement of alanine aminotransferase was also noted. SPSS 19 was used for data analysis. Results: Of the 113 subjects, 73(64.6%) were male and 40(35.4%) were female. Overall improvement was observed in subsequent alanine aminotransferase levels (491 units per litre, IQR 356.5 TO 775 vs 151 units per litre, IQR 49.5 to 299.5). Most commonly prescribed dose of paracetamol was 2g (IQR 1 to 5 grams), which was taken for a median duration of 1 day (IQR 1 to 3 days). Moreover, 100(88.5 %) patients showed improvement in alanine aminotransferase. Only 13(11.5 %) patients developed worsening of alanine aminotransferase. Of those with worsening liver function, 8(61.5 %) were discharged home with no clinical deterioration and 5(38.5 %) deaths were observed. However, causes of deaths were unrelated to liver dysfunction. Conclusion: The frequency of worsening liver function following paracetamol administration in patients with severe dengue hepatitis was relatively low

Feto-maternal Outcome of Reverse Breech Extraction versus Dis-impaction of Fetal Head in Caesarean Section for Obstructed Labour

Objectives: Obstructed labour is an obstetrical emergency with adverse feto-maternal consequences and caesarean delivery in such cases requires skillful handling of impacted fetal head. Objective of our study was to guide clinician about caesarean technique that facilitates the delivery with least complications for mother and baby. Methods: It was a randomized clinical trial with non-probability consecutive sampling conducted at –removed for blind review---from 1st july 2018 – 30th june 2020. Patients who underwent emergency cesarean section were randomized to undergo either push technique for delivery of impacted fetal head (Group A) or reverse breech extraction method (Group B) via lottery method. The data of 60 patients who fulfilled the inclusion criteria was analyzed using SPSS version 19. Maternal outcome measured were extension of uterine incision, blood transfusion, postpartum pyrexia, wound infection, postpartum hemorrhage and length of hospital stay. Fetal outcome measured were 5 minutes Apgar score, birth weight and NICU admission. Results: The results of our study showed statistically significant difference between extension of uterine incision(p-value=0.015), blood transfusion during surgery (p-value=0.021) and postpartum hemorrhage (p-value=0.020) in two groups with pull technique associated with less traumatic extension of uterine incision, less intraoperative transfusion and less PPH than push technique of fetal delivery. Length of hospital stay was also significantly less in reverse breech extraction group(p-value=0.001).More patients had postpartum pyrexia, wound infection, low 5-min Apgar score and NICU admissions in cephalic delivery group but results were not statistically significant. Conclusion: The results of our study recommend reverse breech extraction technique to be a safe alternative to conventional vaginal pushing of fetal head especially regarding maternal outcomes during caesarean section of patients with obstructed labour for fetal delivery. Key words: Obstructed labour, impacted fetal head, reverse breech extraction, caesarean sectio

A Generalized Class of Circular Designs Strongly Balanced for Neighbor Effects

Minimal strongly balanced neighbor designs are useful (i) to minimize the bias due to neighbor effects economically, and (ii) to estimate the direct effect and neighbor effects independently. Such designs can easily be obtained for v odd and are available in literature. In this article, A generalized class of minimal circular designs strongly balanced for neighbor effects in blocks of equal and two different sizes have been constructed in which only v/2 unordered pairs of treatments do not appear as neighbors, where v is the number of treatments

Triggering and protective factors of burnout in medical resident physicians in a lower-middle-income country: A cross-sectional study

Background: Residents and interns are prone to emotional and physical exhaustion, also known as burnout. Burnout has not been studied much in physicians working in lower-middle income countries. We conducted this study to determine the burden of burnout among internal medicine residents and to identify triggering and protective factors associated with burnout.Materials and methods: A cross-sectional study was conducted at two institutes in Karachi from 2018 to 2019. All residents registered in the internal medicine program for at least 6 months were invited to participate via an online survey. An abbreviated version of the Maslach Burnout scale was used to measure burnout, and protective and triggering factors were recorded according to known factors.Results: A total of 71 out of 92 (77%) residents participated. The mean (SD) age of the participants was 28 (3.1) years, 51 (71.8%) were females and 51 (71.8%) were junior residents. A total of 33 (46.5%) residents had burnout. Burnout and emotional exhaustion were more in female residents (p \u3c 0.05). None of the triggering factors attained statistical significance. The protective factors for burnout which showed significant association were good relationship with friends (OR 0.1-95% CI 0.0, 0.6), exercise and extra-curricular activities (OR 0.2-95% CI 0.0, 0.7), celebrating accomplishments (OR 0.2-95% CI 0.0, 0.7), having enough money (OR 0.2-95% CI 0.0, 0.4), and ability to plan for future (OR 0.1-95% CI 0.0, 0.6).Conclusion: More than a third of medicine residents suffered from burnout. We need to focus on rejuvenating activities for medicine residents to decrease burnout among them. If not addressed adequately this may result in a compromise in the quality of care being provided to patients

Efficient synthesis of 2-amino-6-arylbenzothiazoles via Pd(0) Suzuki cross coupling reactions : potent urease enzyme inhibition and nitric oxide scavenging activities of the products

In general, benzothiazole derivatives have attracted great interest due to thier pharmaceutical and biological importance. New 2-amino-6-arylbenzothiazoles were synthesized in moderate to excellent yields via Suzuki cross coupling reactions using various aryl boronic acids and aryl boronic acid pinacol esters and the antiurease and nitric oxide (NO) scavenging activity of the products were also examined. The most active compound concerning urease enzyme inhibition was 6-phenylbenzo[d]thiazole-2-amine 3e, with an IC50 value of 26.35 µg/mL. Compound 3c, 6-(4-methoxyphenyl) benzo[d]thiazole-2-amine, exhibited the highest nitric oxide percentage scavenging at 100µg/mL

Distance and Engagement: Hegel’s Account of Critical Reflection

Hegel famously argues that Kant’s account of critical distance depends upon an impoverished conception of freedom. In its place, Hegel introduces a richer conception of freedom, according to which the self who is capable of self-determination is multifaceted: wanting and thinking, social and individual. This richer conception gives rise to an account of critical reflection that emphasizes engagement with our motives and practices rather than radical detachment from them. But what is most distinctive about Hegel’s account is the idea that when we reflect upon motives and practices, we draw upon shared self-understandings that are neither universal nor just particular to individuals. There is, Hegel argues, no presocial identity or self that can be detached from our socially constituted contexts of thought and value. This has important implications for how we conceive of critical reflection
