New Onset Refractory Status Epilepticus As An Unusual Presentation Of A Suspected Organophosphate Poisoning, Shahan Waheed, Amber Sabeen, Nadeem Ullah Khan

Department of Medicine

New onset refractory status epilepticus (NORSE) is a new entity in medical literature. It has different infectious and noninfectious etiologies showing a devastating impact onto the clinical outcome of patients. Therapy with anaesthetic and antiepileptic agents often fails to improve the condition, unless the primary cause is rectified. Here is presented the case of a young female with a history of depression who after a recent bereavement came to the Emergency Department of Aga Khan University Hospital with complaints of drowsiness that lasted for few hours.

Emerging Antiretroviral Drug Resistance In Sub-Saharan Africa: Novel Affordable Technologies Are Needed To Provide Resistance Testing For Individual And Public Health Benefits, Gert U. Van Zyl, Lisa M. Frenkel, Michael Chung, Wolfgang Preiser, John W. Mellors, Jean B. Nachega

Internal Medicine, East Africa

In industrialized countries, viral load monitoring and genotypic antiretroviral drug resistance testing (GART) play an important role in the selection of initial and subsequent combination antiretroviral therapy (cART) regimens. In contrast, resource constraints in Africa limit access to assays that could detect virologic failure, transmitted drug resistance (TDR) and acquired drug resistance to cART. This has adverse consequences for both individual and public health. Although the further roll-out of antiretrovirals for prevention, including preexposure prophylaxis (PrEP) and universal test and treat (UTT) strategies, could reduce HIV-1 incidence, these strategies may increase TDR [1,2]. Here, we present arguments that the scale …

Beck, Sandra Dross, Kenneth Tapia, James N. Kiarie, Barbra A. Richardson, Julie Overbaugh, Samah R. Sakr, Grace C. John-Stewart, Lisa M. Frenkel

Internal Medicine, East Africa

Background: Transmitted drug resistance (TDR) is increasing in some areas of Africa. Detection of TDR may predict virologic failure of first-line non-nucleoside reverse-transcriptase inhibitor (NNRTI)-based antiretroviral therapy (ART). We evaluated the utility of a relatively inexpensive oligonucleotide ligation assay (OLA) to detect clinically relevant TDR at time of ART initiation.

Methods: Pre-ART plasmas from ART-naive Kenyans initiating an NNRTI-based fixed-dose combination ART in a randomized adherence trial conducted in 2006 were retrospectively analyzed by OLA for mutations conferring resistance to NNRTI (K103N, Y181C, and G190A) and lamivudine (M184V). Post-ART plasmas were analyzed for virologic failure (≥1,000 copies/mL) at 6 month …

Department of Medicine

This study was conducted to determine the association between place of residence (grouped into neighbourhoods), and 25-hydroxy D (25[OH]D) levels of individuals of Karachi. Addresses of 4788 individuals tested for 25[OH]D at the clinical laboratory of the Aga Khan University (AKU), Karachi, from January 2007 to June 2008 were reviewed. The neighbourhoods were categorized into ten, based on locality attributes. A high overall prevalence (74%) of vitamin D deficiency (VDD) was observed. There was a significant difference (p-value < 0.01) between mean log 25[OH]D levels amongst neighbourhoods grouped according to distinct housing structure attributes and localities. A high frequency of VDD in all the studied localities of an urban city warrant dietary vitamin D supplementation and food fortification.

Effect Of Mobile Phone Short Message Service On Adherence Rates To Antihypertensives At The Family Medicine Clinic, Barbara Karau

Master of Medicine in Internal Medicine

Background: Systemic arterial hypertension is the main modifiable risk factor for development of cardiovascular disease, which is the number one cause of death in high income countries and is increasingly becoming a cause of concern in Sub-Saharan Africa (1). Awareness, management and overall control of hypertension in Sub-Saharan Africa is poor (2,3). Poor control stems from various causes; one being patient non-adherence with medication, a factor amenable to modification. The use of mobile health for behavioural change from low resource settings is gaining widespread use in management of communicable diseases (4,6). Mobile phone has the potential to significantly influence patients …

Unintentional Childhood Poisoning, Epidemiology And Strategies For The Prevention And Policy Change In Pakistan, Omer Ul Hassan, Hasana Qadri, Umer Mir, Bilal Ahmed

Department of Medicine

Poisoning is the fifth leading cause of unintentional injuries among young children. Agents most commonly ingested by young children include medicines, cleaning substances, hydrocarbons, pesticides and cosmetics. Children with less educated fathers, living in more crowded conditions and from lower income families are more predisposed to unintentional poisoning. Unsafe storage of medicines, chemicals and other hazardous substances is one of the leading reasons for childhood poisoning. Knowledge of parents and caregivers about prevention of poisoning may be the basis to prevent subsequent injuries. This paper is a review of the epidemiology of unintentional poisonings among young children (less than five …
