RESUMO
Objective@#The present study aims to investigate the concentrations of Hg and its aspects methyl mercury (Me-Hg) and inorganic mercury (I-Hg) in the biological samples (BSs) of fluorescent lamp industries workers (FLIWs).@*Methodology@#Different BSs including red blood cells (RBCs), plasma, urine, hair and nails were collected from the workers exposed to Hg and unexposed persons were selected as control group to measure both the T-Hg concentration as well as its species in different biological samples through quantitative analysis. Health data was collected through questionnaire survey.@*Results@#The mean concentrations of T-Hg (31.9 µg/L), Me-Hg (27.7 µg/L), and I-Hg (5.36 µg/L) in RBCs were found significantly ( < 0.001) higher among the workers ( = 40) as compared to the control group ( = 40). Similarly the mean Hg concentrations in plasma, urine, hair and nails were also significantly higher among the workers than the control group. The statistical relation between Hg concentration and demographic characteristics observed that workers experience and fish consumption has increased the Hg concentration while age, weight and smoking found no significant effect on Hg concentration in the BSs.@*Conclusion@#The study observed that the workers were highly exposed to high concentration of Hg and they are at a high health risk.
RESUMO
To describe post traumatic pseudoaneurysms and its association to causes, presentation and conventional surgical treatment modalities. This Descriptive study carried out in the Department of Cardiovascular Surgery, Lady Reading Hospital, Peshawar from January 2003 to December 2007. Patients with associated arteriovenous fistula were excluded from this study. All the demographics including age, sex, type of injury, site, associated complications operative details, pen operative morbidity and mortality were prospectively recorded in a data base. The total number of patients was seventy five. All the patients underwent conventional surgical procedures. Reverse saphenous graft was received by 34%, 24% had end to end anastomosis, 12% had interposition synthetic graft, 8% had rent repair while 21.33% had primary ligation of the involved artery. There was no pen operative mortality. Six patients had post operative complication in the form of graft, thrombosis and or infection. Three patients had amputation, two in lower limb and one in the upper limb. Majority of them were male 90.66%. Age ranged from 7 years to 75 years. Most of the patients [77.3%] were in second to fourth decade of life. The most common cause of injury was gunshot wound [56%] followed by stab wounds [13.33%] and road traffic accidents [12%]. Few cases of bomb blast [6.66%], Post cardiac catheterization [4%], glass injury [4%] and intravenous drug abusers [2.66%] were also reported. The commonest site of injury was fern oral artery [37.33%].In this study majority of patients were male with gunshot wound as commonest cause. Reverse saphenous vein graft was treatment of choice. Infection and thrombosis were the commonest postoperative complications
