Oesophageal duplication cyst presenting as haemoptysis.

Duplications of the alimentary tract include a variety of cysts, diverticula, and tubular malformations, all believed to have embryological origin. The cysts are most commonly found in children, and the diagnosis is made in infancy in the majority of patients. We report a case of a two-and-a-half year old child, presenting with the history of repeated episodes of haematemesis. Upper GI endoscopy was unremarkable and the chest x-ray showed no pathology. Computed tomography (CT) angiogram revealed soft tissue density lesion in the right chest at the level of T6. Right thoracotomy suggested a cystic mass close to the oesophagus which was shown on histopathology to be lined with gastric mucosa consistent with oesophageal duplication cyst. To the best of our knowledge, this is the first case of its kind reported from Pakistan.

Frequency of HBsAg positivity: a laboratory data analysis.

The objective of the study was to evaluate the current frequency ratio of HBsAg seropositivity in a laboratory-based setting. It was a retrospective study, conducted during September 2009 and November 2010 at Dr. Essa's Diagnostic Laboratory and its branches in Karachi, Pakistan. Blood samples of 8,648 individuals were screened for HBsAg using the BioRad EVOLIS EIA method. Pertinent questionnaires filled in by 50 practicing physicians were also evaluated. The 551 subjects (6.4%) that tested positive for HBsAg included 360 males (65.3%) and 191 females (34.6%). The highest frequency of HBsAg was noted in those aged 16 - 29 years (43.9%). HBsAg rate in the studied population has steadily increased and is more common in the sexually active age group, with males tending to be more often seropositive than females.

The legal excavation of dead bodies for ascertainment of the cause of death has always aided the law enforcement agencies to comprehend the anonymity of any suspicious case and further convict the criminal in cases of homicides. This study analyses the different aspects of the exhumations which were carried out and were autopsied in Karachi during the study period. METHOD: This was a cross-sectional study, and included all the exhumations carried out in Karachi during a period of 7 years and 7 months from 1 January 2004 to 31 July 2011.

Causes of death were ascertained in 75 cases, thus the success rate was 74.3%. Head injury by hitting with hard blunt object was the most frequent cause of deaths (17.8%), followed by asphyxia due to strangulation (15.8%). DISCUSSION: Exhumations must be ordered by the Judiciary in suspicious cases as it aids in determining the actual causes of death and leads to convictions.
