Patterns of antibiotic prescriptions and appropriateness in the emergency room in a major secondary care hospital in Bahrain

Objective: To describe the pattern and appropriateness of antibiotics prescribed in the emergency room in a major secondary care hospital in Bahrain.Methods: Patients aged more than or equal to 14 years old that attended emergency room and was prescribed antibiotics from 1 to 31 July 2014 were included. Data were obtained from patients’ emergency records. Antibiotic treatment was classified to appropriate, inappropriate or unjustified use according to the local or international guidelines. Chi Square was performed to evaluate the variables associated to appropriateness antibiotic treatment.Results: A total of 1313 patients were included (52.6% males), mostly in the age group 14-30 years old (45.3%). The most frequent diseases attended were upper respiratory and urinary tract infections (27.3% and 22.1%,respectively). Cefuroxime was the most prescribed antibiotic (37.5%) followed by ciprofloxacin (20.8%). Percentage of inappropriate antibiotics prescription was 81.9% mostly due to unjustified use. Inappropriate antibiotic treatment was significantly more common in males (87.1%; P-value <0.001), in patients without mentioned diagnosis, then upper respiratory tract infection (100%, 96.9%. P-value <0.001) and prescriptions written by emergency physicians (85.5%; P- value <0.001).Conclusion: The study concludes that high rate of inappropriate antibiotics use mostly among patients treated by emergency doctors

A Novel Mutation in a Gene Causes Sclerosteosis in a Family of Mediterranean Origin

Background and Objectives: Sclerostin is an SOST gene product that inhibits osteoblast activity and prevents excessive bone formation by antagonizing the Wnt signaling pathway. Sclerosteosis has been linked to loss of function mutations in the SOST gene. It is a rare autosomal recessive disorder characterized by craniotubular hyperostosis and can lead to fatal cerebellar herniation. Our aim is to describe the clinical and radiological features and the new underlying SOST mutation in a patient with sclerosteosis. Case: A 25-year-old female who was referred to the endocrine clinic for suspected excess growth hormone. The patient complained of headaches, progressive blurred vision, hearing disturbances, increased size of feet, proptosis, and protrusion of the chin. She had normal antenatal history except for syndactyly. Images showed diffuse osseous thickening and high bone mineral density. Biochemical and hormonal tests were normal. Due to progressive compressive optic neuropathy, optic nerve fenestration with decompression hemicraniotomy was performed. Sclerosteosis was suspected due to the predominant craniotubular hyperostosis with syndactyly. Using peripheral leucocyte DNA, genomic sequencing of the SOST gene was performed. This identified a novel deletion homozygous mutation in the SOST gene (c.387delG, p.Asp131ThrfsTer116) which disrupts sclerostin function, causing sclerosteosis. Conclusions: Discovery of the molecular basis of sclerosteosis represents an important advance in the diagnosis and management of this fatal disease
