Childhood obesity and Pakistan.

Obesity and overweight have become a problem of public health magnitude associated with substantial economic burden not only in the developed countries but also in the developing countries. The number of overweight children and adolescents has doubled in the last two decades in the United States and worldwide, including developing countries. No study on childhood obesity and overweight is available in Pakistan. Obesity in children impacts on their health in both short and long-term and obesity and its preventive strategies are poorly understood. Increasing number of these children and adolescents all over the world demand not only a substantial political will but also an investment for primary and secondary preventive measures and novel approaches in the treatment modalities.

Fatal double aortic arch anomaly and maternal cocaine abuse.

We report a case of 2 months old female (born to a cocaine abuser mother) having respiratory dysfunction attributed to pneumonia. Autopsy, following a sudden, unexpected death, revealed a double aortic arch which was compressing the trachea and the esophagus. Health care professionals should conduct a detailed cardiac assessment on all cocaine-exposed infants at the time of birth and during infancy. Double aortic arch should be considered as a possible complication of intrauterine cocaine exposure and may present as sudden death.

Students' misconception in respiratory physiology.

BACKGROUND: Misconceptions in Physiology are common and are carried into later years of medical education, perhaps leading to difficulty in understanding Pathology and Medicine later on. To find the prevalence of misconceptions in Respiratory Physiology, one question was asked to 1st, 2nd, 3rd and 4th year MBBS students while they were still studying basic sciences and the response was analyzed accordingly. METHODS: The question was asked "What happens to the tidal volume during exercise?" to 153 MBBS medical students during their first to fourth year medical education and they were asked to pick the right answer from three choices. RESULTS: The correct answer was picked by 35% of students from all four classes. Furthermore, class wise distribution of the data revealed that correct answer was given maximally by first year students (45%) and fourth year students (43%). But, only 27% and 8% of second and third year students answered the question correctly. CONCLUSION: This data shows the extent of prevalence of misconceptions in Respiratory Physiology among medical students during their years of medical education at one medical institute in Pakistan.
