Frequency Of G6pd Mediterranean In Individuals With And Without Malaria In Southern Pakistan, Bushra Moiz, Haroon Muhammad Arshad, Ahmed Raheem Raheem, Hasan Hayat, Najia Karim Ghanchi, M Asim Beg
Department of Pathology and Laboratory Medicine
Background: Pakistan has an estimated annual burden of 1.5 million malaria cases. The current situation calls for an efective malaria control and eradication programme in this country. Currently, primaquine is an attractive option for eliminating reservoirs of Plasmodium vivax hypnozoites and killing gametocytes of Plasmodium falciparum. However, this drug causes haemolysis in individuals who are glucose-6-phosphate (G6PD) defcient. It is important to map G6PD defciency and malaria distribution in Pakistan to design an efective malaria eradication regimen. Frequency of G6PD defciency (G6PDd) in malaria patients has not been reported from Pakistan in any meaningful way. The purpose of this study …

Department of Pathology and Laboratory Medicine
A cross-sectional survey was done at the Section of Chemical Pathology, Department of Pathology and Laboratory Medicine, AKUH, Karachi, to determine frequency of Zn deficiency, the second major micronutrient deficiency in developing countries, in subjects coming for investigations. Data of plasma Zn, from Jan 2013 to Dec 2014 was analyzed and deficiency was labeled at <65ug/dl. Total 469 subjects were tested for plasma Zn levels over the period of 24 months and complete information was available for 422 subjects, included in final analysis. Median age of subjects was 13 yrs (IQR 7-35) and 57% were male. Mean plasma Zn levels of the total subjects were 105±42.6ug/dl. Out of the total subjects 13.5% (n=57) had Zn deficiency (mean plasma Zn 52±11 ug/dl), and most of them were of age group 6-16yrs. These findings advocate that diet of Pakistani children should be revised in order to provide sufficient amounts of Zn.

Pulmonary Infections After Tuberculosis, Kauser Jabeen
Department of Pathology and Laboratory Medicine
Aims and Objective: Despite effective treatment of pulmonary tuberculosis (TB) patients, destruction of lung parenchyma may lead to complications including repeated infections. These infections are often misdiagnosed or wrongly identified as TB recurrence, and hence are not treated effectively. The frequency and severity of these infections vary with the extent of damage, and are much more prominent in patients with post-TB bronchiectasis and fibrocavitary diseases. This presentation will focus on the epidemiology, treatment, and management of post-TB infections and challenges, and the impact of these infections on public health in high-TB-burden countries.
Methods: Published literature and review articles were evaluated …
