High Burden Of Subclinical Lead Toxicity After Phase Out Of Lead From Petroleum In Pakistan, Hafsa Majid, Aysha Habib, Nadeem Ullah Khan, Imran Siddiqui, Farooq Ghani, Lena Jafri
Department of Pathology and Laboratory Medicine
Objective: To evaluate the frequency of subclinical lead toxicity.
Study design: Cross-sectional study.
Place and duration of study: Department of Pathology and Laboratory Medicine, The Aga Khan University Hospital, Karachi, from January 2011 to December 2014.
Methodology: Analysis of laboratory data for blood lead levels (BLL) was performed. Lead was tested by atomic absorption spectrometer. For all subjects, only initial test results were included while the results of repeated testing were excluded. Exemption was sought from institutional ethical review committee. BLL of 2-10 ug/dl and 10-70 ug/dl in children and adults, respectively were taken as subclinical lead toxicity.
Result: Amongst …

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.

Selective Screening For Organic Acidurias And Amino Acidopathies In Pakistani Children, Noreen Abbas Sherazi, Aysha Habib Khan, Lena Jafri, Azeema Jamil, Nasir Ali Khan, Bushra Afroze
Department of Pathology and Laboratory Medicine
Objective: To determine the frequency of organic acidurais (OA) and amino acidopathies (AA) in selected high-risk patients screened in two years.
Study Design: Retrospective Observational study.
Place and Duration of Study: The Aga Khan University Hospital (AKUH), Karachi, from January 2013 to December 2014.
Methodology: Patients with OA and AA were included in the study and patients with IMDs other than OA and AA were excluded. Amino acids and organic acids were analyzed on high performance liquid chromatography and gas chromatography-mass spectrometry respectively. Clinical data and chromatograms of patients screened for IMDs were reviewed by chemical pathologist and metabolic physician. …
