Obstructive jaundice--an unusual complication of duodenal tuberculosis: treatment with transhepatic balloon dilatation

This is a report of a patient on treatment for duodenal tuberculosis, who developed obstructive jaundice due to a benign stricture of the terminal common bile duct. This complication of duodenal tuberculosis, to our knowledge, has not been reported before. Percutaneous, transhepatic balloon dilatation of the stricture alleviated the jaundice.     

Insulin dependent diabetes in children

We present our experience with twenty children with insulin dependent diabetes mellitus admitted during the past 2 1/2 years. Sixteen patients were admited with acute onset of ketoacidosis while four were having gradual onset. Active and symptomatic treatment was started in all diabetic ketoacidotic patients. One patient died during the acute stage. Eleven patients were followed for 3–6 months or more. Glycosylated hemoglobin was considered as a criteria for control. Three had good control, two fair and six poor control; six developed diabetic ketoacidosis and three developed hypoglycemia     

Is antibiotic prophylaxis necessary for routine urodynamic investigations? A controlled study in 100 patients

The value of a prophylactic antibiotic before a routine cystometrogram has been assessed in a controlled trial of 100 patients. The infection rate was low and not statistically different in both groups. Subsequent symptoms of dysuria and haematuria had a mechanical aetiology.     

Treatment of an Amalgam Tattoo with a Q-Switched Alexandrite (755 nm) Laser

BACKGROUND: Amalgam tattoos result from deposition of metallic particles (eg, silver, mercury, copper, zinc, and tin) into the oral mucosa. Their clinical and histologic appearance is similar to that of decorative tattoos. OBJECTIVE: To describe the successful use of a Q-switched alexandrite laser for removal of an amalgam tattoo. MATERIALS AND METHODS: An amalgam tattoo on the buccal mucosa and gingiva was treated with a QS 755 nm alexandrite laser. Three treatments were delivered at 8-week time intervals (average fluence = 6.8 J/cm2). RESULTS: Significant lightening of the tattoo was achieved after each of the three treatments without adverse sequelae. CONCLUSION: Q-switched alexandrite laser irradiation can safely and effectively eradicate amalgam tattoos.     

Endocrine changes in Alzheimer's disease

In conclusion, at present, no consistent endocrine abnormalities can be detected in patients suffering from Alzheimer's disease. However, assessment of neuroendocrine function might help identify subpopulations of patients with particular neurotransmission abnormalities who are likely to benefit from a specific pharmacologic strategy. For example, patients in whom cholinomimetic drugs produce the greatest elevation in plasma cortisol concentration appear to derive the most symptomatic benefit from these drugs.     

MR imaging of spinal cord hemangioblastoma associated with syringomyelia

A case of isolated spinal cord hemangioblastoma with associated extensive syringohydromyelia, which was evaluated by myelography, postmyelographic CT, magnetic resonance (MR), and angiography is presented. The specific preoperative and postoperative advantages of MR are given as well as a brief review of the literature.     

Giant right atrial diverticulum: an unusual cause of Wolff-Parkinson-White syndrome.

A case of a giant right atrial diverticulum associated with neonatal supraventricular tachycardia is reported. The electrocardiogram in sinus rhythm showed pre-excitation that may have been caused by the right atrial diverticulum adhering to the right ventricle.     

Biology of genital tract human papillomaviruses.

A large number of HPV types infect humans. They infect squamous epithelia of the skin and mucous membranes. Infections are widespread in sexually active populations. Some HPV types have oncogenic potential. Infections with HPV-16, HPV-18, and some additional types are risk factors for cervical cancer. The HPV-6 and HPV-11 types are responsible for most of the genital condylomas and nearly all respiratory papillomas. The immunologic responses to HPVs are not well understood.
