#1
Sabah M Al-Shukry
A 40-year-old woman presented with the history of swallowing a fishbone one hour earlier. Since the patient was swallowing normally and the X-ray results were negative, she was reassured and sent home. Twenty days later, when the patient again presented with pain and tenderness in her neck, the fishbone was detected in the left sternomastoid muscle, and removed under local anaesthesia.

Pica, where the patient eats non-food items such as mud, clay, varnish etc., is a common behavioural problem seen in children, pregnant women and the mentally retarded. However sponge pica is a very rare variation. We report a case of a 5-year-old Omani girl, who presented with sponge pica since the age of two years, with recent abdominal pain. Investigations showed anaemia, elevated liver enzymes and normal intelligence. There was no evidence of obsessive-compulsive disorder. Both clinical and laboratory findings showed complete recovery after a few weeks of oral iron therapy...

REVIEW
Ali A Al-Jabri
To insure its survival, the human immunodeficiency virus (HIV), the causative agent of acquired immunodeficiency syndrome (AIDS), utilises more than one gate to enter a target cell. This strategy makes it more difficult for the immune system to defeat the virus. This has also made it difficult for scientists working in the HIV research to understand how exactly HIV infects a susceptible human cell. Such understanding will no doubt open many gates for scientists to vanquish the virus by designing agents that can block HIV entry into target cells, thus rendering the virus vulnerable to immune destruction...

REVIEW
Neela Lamki, Alfred B Watson, Richard G Fisher
Like in other medical fields, candidates seeking a career in Radiology requires special skills and aptitudes. Selecting candidates for radiology residency is made difficult by the fact that many of the essential qualities predictive of a good radiology consultant, such as interpersonal skills, recognition of limits, curiosity, conscientiousness, and confidence level, are "non-cognitive", and thus difficult to assess. This paper describes the selection procedure developed by the Department of Radiology of Baylor College of Medicine to measure, as objectively as possible, both the cognitive and non-cognitive qualities of candidates, based on a combination of traditional screening and Objective Structured Interviews...

The paper reports the case of a previously healthy 4-year-old-girl who presented with pallor, fever and hepatosplenomegaly. Laboratory findings included pancytopenia, hypertriglyceridemia and hyperferritinemia. Initial diagnosis of kala-azar could not be confirmed because of the absence of clinical evidence, negativity of bone marrow aspiration or specific serology for visceral leishmaniasis. Repeated marrow aspiration, performed due lack of clinical response, revealed histiocytes showing haemophagocytosis consistent with haemophagocytic lymphohistocytosis (HLH) and appropriate treatment was started...

Foreign bodies in the upper aero-digestive tract pose major challenges to the otolaryngologist in both diagnosis and management. Aspirated and ingested foreign bodies are often emergencies, leading to inadequate study and poorly prepared, improper attempts at removal. The authors share their experience in managing upper aero-digestive tract foreign bodies in Omani population at a district hospital, present a statistical review of 58 cases, and highlight certain critical scenarios as well as cultural variations specific to the region...

There are various causes of hyperthyroidism in pregnancy such as Graves' disease and gestational thyrotoxicosis. The thyroid stimulation results from the excessive levels of circulating human chorionic gonadotropin (hCG) produced by the trophoblastic tissue in both hydatidiform moles and choriocarcinoma. We present a pregnant patient with hydatidiform mole who presented with hyperthyroidism that resolved after evacuation of the mole.

K Bhargava, R Jaeschke
Evidence-based Medicine (EBM) has been proposed as the most significant intellectual advance in the process of clinical decision-making in the past decade. With more than 25,000 medical journals publishing 4 million articles a year, doctors are unable to cope with the information overload. The principles and practice of EBM show the way to bridge the gap between research and practice. Reactions evoked in the medical profession towards this new discipline have been in extremes, from outright rejection to enthusiastic acceptance...
