We read with interest the article published in your Journal entitled “Real-world persistence with antiretroviral therapy for HIV in the United Kingdom: a multicentre retrospective cohort study”1 which concluded that treatment discontinuation attributable to toxicity profile is not an uncommon event. They also acknowledged lack of data collection on HLA-B*5701 status, which would heavily influence initial ART regimen and the choice to discontinue medication. Of the 25.6 million living with Human Immunodeficiency Virus (HIV) in Africa, an estimated 1.6 million people live in Kenya.2 With an HIV prevalence of 5.6%, Kenya has upscaled HIV treatment and care in the past …

Introduction: Oral squamous cell carcinoma (OSCC) the sixth leading cancer worldwide ranks as the most common cancer in males, and the third most common in females in Pakistan. It is influenced by risk factors which are widely consumed in our population. The epidermal growth factor receptor (EGFR) is a tyrosine kinase receptor that is imperative for cell signalling, growth and differentiation. It is mutated and overexpressed in a variety of cancers, while in OSCC it has been linked to poor patient survival; premalignant to malignant transformation and recurrence. This study investigates the use of EGFR as a prognostic factor …
Ectopic Enterobius Vermicularis Iinfestation; An Extremely Rare Cause Of Mesenteric Lymphadenopathy Mimicking Tuberculous Lymphadenitis, Summaya Zafar, Muhammad Usman, Zubair Ahmad
Ectopic Enterobius Vermicularis Iinfestation; An Extremely Rare Cause Of Mesenteric Lymphadenopathy Mimicking Tuberculous Lymphadenitis, Summaya Zafar, Muhammad Usman, Zubair Ahmad

Enterobius vermicularis (EV) is a pinworm which commonly resides in the lumen of the intestinal tract and lays eggs on the perianal skin. However, rarely the worm can infest various other sites in the body and cases with infestation of such ectopic sites have been reported in literature. Rare cases of mesenteric lymph node involvement have also been reported. We report a case in a young male who presented with signs and symptoms of acute appendicitis. During surgery, enlarged mesenteric lymph nodes were identified. Histological examination revealed adult worm in the appendiceal lumen. Histological examination of mesenteric lymph node revealed …
Fulminant Hemolysis In Glucose-6-Phosphate Dehydrogenase Deficiency, Bushra Moiz, Sidra Asad Ali
Fulminant Hemolysis In Glucose-6-Phosphate Dehydrogenase Deficiency, Bushra Moiz, Sidra Asad Ali
Department of Pathology and Laboratory Medicine
Key Clinical Message
Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an X-linked disorder affecting some 400 million people worldwide. Though clinically silent, it may result in hemolysis on oxidative stress induced by drugs or infections. Viral hepatitis A with coexisting G6PD deficiencycan be devastating associated with severe hemolysis, anemia, renal failure, and hepatic encephalopathy.

Point-of-care testing (POCT) coagulometers are increasingly being used in the hospital setting and patients’ self-testing. We determined the agreement of prothrombin time international normalized ratio (INR) results by POCT coagulometer and laboratory instrument through a comparative analysis and investigated whether the results of POCT coagulometer can reliably be used without being confirmed by standard laboratory analyzer. A total of 200 INR measurements by POCT coagulometer (CoaguChek XS Pro) and laboratory analyzer (Sysmex CS2000i) were compared using Passing-Bablok regression analysis and Bland-Altman plot. Agreement of the INR measurement was further analyzed in relation to dosing decision. The correlation of INR measurements …

Spoon Nails: Still Seen In Today's World, Bushra Moiz
Department of Pathology and Laboratory Medicine
Koilonychia is a nail abnormality characterized by thin, brittle, and spoon-shaped nails. It is frequently observed in chronic iron deficiency secondary to malnutrition, chronic blood loss, or malabsorption. It may also be idiopathic or related to occupation and rare systemic disorders. Presence of koilonychia should prompt investigations for iron deficiency.

Plasmodium vivax is the most common specie causing malaria outside Africa with approximately 13.8 million reported cases worldwide. We report case of P. vivax infection with cerebral involvement. A nine year old boy presented with high grade fever accompanied by projectile vomiting and abnormal behavior later he developed seizures, shock, and unconsciousness. P. vivax monoinfection was diagnosed based on peripheral smears and PCR. After antimalarial therapy, patient made full recovery. Current case highlights increasing trend of cerebral complications caused by P. vivax.

Objective: Fecal contamination of potable water leads to unsafe water supply. Although many urban areas of large metropolitan cities receive safe water, peri-urban areas are often not monitored by public health authorities and water supply and quality remain unknown. We assessed microbiological quality and rates of antimicrobial resistance in viable indicator bacteria in two peri-urban communities of Karachi, Pakistan. Water samples were collected over 5 months (October 2015 to February 2016) from these peri-urban communities and samples were processed for microbiological quality as per Standing Committee of Analysts, United Kingdom and World Health Organization guidelines and criteria for drinking water. …

Purpose:
To compare the results of a chemical method of kidney stone analysis with the results of Fourier transform infrared (FT-IR) spectroscopy.
Materials and Methods:
Kidney stones collected between June and October 2015 were simultaneously analyzed by chemical and FT-IR methods.
Results:
Kidney stones (n=449) were collected from patients from 1 to 81 years old. Most stones were from adults, with only 11.5% from children (aged 3-16 years) and 1.5% from children aged adults, the calcium oxalate stone type, calcium oxalate monohydrate (COM, n=224), was the most common crystal, followed by uric acid and calcium oxalate dihydrate (COD, n=83). In …
