Pulmonary function studies in Kuwaiti children with sickle cell disease and elevated Hb F.
Conflicting ventilatory defects have been reported in children with sickle cell disease (SCD). In Kuwait, the disease is relatively mild with a low incidence of acute chest syndrome and other complications, presumably due to the Arab-Indian haplotype chromosomal background and elevated Hb F levels. There have been no previous studies of pulmonary function in patients with this haplotype. ⋯ This study revealed an early restrictive and obstructive pulmonary function pattern in steady state children with SCD. The finding also indicates that the changes of PFT parameters in SS patients could not be attributed to anaemia per se as patients with HbH who also have chronic anaemia did not show similar changes. This observation underscores the early occurrence of pulmonary involvement, even in patients with an otherwise relatively mild SCD.

Chronic daily headache (CDH), which is often linked to a history of migraine, tension-type headache and the abuse of headache medications, and cluster headache are the best known of the chronic headaches. These headaches may not be well recognised or well treated in primary care. This article outlines the development of management algorithms for these headache subtypes, designed for use by the primary care physician with an interest in headache. ⋯ The optimal treatments for CDH include physical therapy to the neck if there is any stiffness there, withdrawal of abused medications and treatment of any subsequent withdrawal symptoms and headache prophylaxis, together with the provision of acute medications as rescue therapy. Optimal treatments for cluster headache include short- and long-term prophylaxis to prevent the headaches developing and acute medications for use as rescue. If treatment is ineffective, alternative medications can be provided at follow-up, with the possibility of referral for refractory patients.

Ibuprofen abuse may be more prevalent than generally considered. Although normally benign, serious complications have been documented. We report an unusual presentation of hypokalaemia and its associated symptoms as a result of Nurofen Plus (200 mg ibuprofen + 12.8 mg codeine phosphate) abuse. Ibuprofen is generally not included in a standard toxicology screen, but should be considered as a rare cause of hypokalaemia.

Randomized Controlled Trial Clinical TrialEffect of ascorbic acid on surgical stress response in gynecologic surgery.
Surgical stress may cause neural, endocrine, metabolic and humoral responses depending on the severity of the procedure. In this study, we aimed to study the effect of the preoperatively given ascorbic acid (AA), which is an antioxidant, and its role in the biosynthesis of neuropituitary hormones on the surgical stress response. Twenty-two American Society of Anaesthesiologists I and II patients ageing between 18 and 40, who have no endocrine and metabolic disease, and undergoing abdominal operation for non-malignant diseases were allocated to the study. ⋯ Whereas, patients in Group II had higher levels of cortisol than the control group at sixth hour, which were in normal limits, and there was no decrease in osteocalcin concentration. ACTH level was increased at the second and sixth hours, which was statistically significant, but at twelfth and twenty-forth hours, they were close to control group levels. As a result, we conclude that AA given before anaesthesia achieved by etomidate is not sufficient for the prevention of surgical stress response and that AA induction before anaesthesia should be preferred, particularly for the prevention of decrease in osteocalcin levels.

Case ReportsThe place of the ice pack test in the diagnosis of myasthenia gravis.
In the evaluation of ptosis, the ice pack test is a simple, quick, bedside method to ascertain whether it is of myasthenic origin, which requires no specialised medication or equipment and is free of reported adverse effects. Pooling of published studies suggests very high sensitivity, specificity and likelihood ratios, but standardisation and operationalisation of the test are important. False-negative tests may occasionally occur.
