Case Reports
Foreign body in the vallecula presenting as acute epiglottitis with unilateral supraglottitis.
Life threatening inflammatory swelling of the epiglottic and supraglottic regions secondary to a foreign body in the vallecula is an unusual occurrence. Upper airway obstruction is potentially a life threatening sequela. We present a unique case of acute epiglottitis with unilateral supraglottitis secondary to foreign body in the vallecula, which gradually improved after emergency endotracheal intubation for respiratory arrest, followed by intensive conservative management with intravenous antibiotics, cortisone and intravenous fluids. This case emphasizes that a foreign body in the vallecula presenting with severe dysphagia should be taken seriously as it may lead to life threatening complications.

Review Case Reports
Pulmonary hyalinizing granuloma. Bilateral pulmonary nodules associated with chronic idiopathic thrombocytopenic purpura.
We report a case of a 30-year-old female who had been treated periodically with steroids for idiopathic thrombocytopenic purpura ITP over the last 10 years. Recently, during the course of investigation, she was found to have incidental asymptomatic multiple pulmonary nodules on chest CT. ⋯ The remaining 2 nodules regressed on increasing her dose of steroids. The case is discussed with emphasis on the histological and radiological differential diagnosis, in addition to including ITP among the spectrum of immunologic conditions associated with PHG.

Comparative Study
Comparison of bone mineral density with dual energy x-ray absorptiometry, quantitative ultrasound and single energy x-ray absorptiometry.
We conducted this prospective study to establish the correlation between dual energy x-ray absorptiometry (DXA), quantitative ultrasound (QUS) and single energy x-ray absorptiometry (SXA) and to establish the role of QUS and SXA as a screening tool for osteoporosis. ⋯ The correlation between all modalities was significant, but varied from high to low. It was high between lumbar spine and femoral neck, moderate between lumbar spine and forearm and low between lumbar spine and QUS of heel. When we used the same WHO criterion of T-score (more than -2.5 SD below normal), QUS detected significantly less numbers with osteoporosis. We conclude that with the present cut-off of T-score, the QUS may not be used as a screening tool. It may need some modification of T-score. However, we need larger multi-center studies with a larger number of patients for further validation.

Biography Historical Article
Contributions of Ibn Zuhr (Avenzoar) to the progress of surgery: a study and translations from his book Al-Taisir.
This study of the original Arabic edition of the book Al-Taisir Fil-Mudawat Wal-Tadbeer (Book of Simplification Concerning Therapeutics and Diet) written by the Muslim physician Abu-Marwan Abdel-Malik Ibn Zuhr (Avenzoar, 1093-1162 AD) aimed at evaluating his contributions to the progress of surgery and providing English translations of relevant excerpts. Ibn Zuhr s unique experiment performing a tracheotomy on a goat, proved the safety of this operation in humans and represented a further step in the development of the experimental school started by Al-Razi (Rhazes) of Baghdad in the ninth century who is known to have given monkeys doses of mercury to test it as a drug for human use. Ibn Zuhr also performed post mortems on sheep in the course of his clinical research on treatment of ulcerating diseases of the lungs. ⋯ He also drew the red lines at which a physician should stop, during his general management of a surgical condition; a step forward in the evolution of general surgery as a specialty of its own. He believed in prophylaxis against urinary stone disease and reported the importance of dietary management for that purpose. Furthermore, Ibn Zuhr enriched surgical and medical knowledge by describing many diseases and treatment innovations not ever described before him.

We compared the postischemic cerebral protective effects of sevoflurane and desflurane in rats with incomplete cerebral ischemia. ⋯ These data indicate that sevoflurane and desflurane have cerebral protective effects when given after ischemia.
