Stapled haemorrhoidopexy versus Ferguson haemorrhoidectomy: a prospective study with 2-year postoperative follow-up.

Patients with grade III or IV haemorrhoids underwent stapled haemorrhoidopexy or Ferguson haemorrhoidectomy (50 patients in each group) between June 2000 and April 2003. Six patients (12.0%) receiving stapled haemorrhoidopexy experienced complications: bleeding (2.

Psychotic disorder induced by oxybutynin: Presentation of two cases.

Anticholinergic agents are muscarinic receptor antagonists that suppress the activity of the acetylcholine system in the brain. Some of these agents also increase the concentration of dopamine in the synaptic cleft, which may result in psychotic symptoms. Oxybutynin is an antimuscarinic drug that may have adverse effects on the CNS, including memory impairment, confusion, delirium and hallucinations in elderly patients.

Reliability of fine-needle aspiration in patients with familial nonmedullary thyroid cancer.

In this case-control study we describe how often thyroid cancers and occult cancers are diagnosed or not diagnosed by fine-needle aspiration (FNA) in patients with thyroid nodules and a family history of nonmedullary thyroid cancers (FNMTC). Our hypothesis is that patients with thyroid nodules and a family history of FNMTC seem to be similar to patients with thyroid nodules and a history of exposure to low-dose therapeutic radiation. Both have been reported to have multifocal thyroid neoplasms and malignant tumors are common.

Management of thyroid carcinosarcoma.

Background: Thyroid carcinosarcoma is a rare and aggressive malignant thyroid tumor that has been described pathologically, but there is little clinical information regarding tumor behavior.

Methods: We retrospectively analyzed the course of our patient and 16 others reported in the literature to determine optimal management. We review the case history of our patient and the literature concerning patients with carcinosarcoma of the thyroid.

Sestamibi scanning is inadequate for directing unilateral neck exploration for first-time parathyroidectomy.

Objective: To determine whether technetium Tc 99m sestamibi scanning is accurate enough to allow surgeons to perform unilateral neck exploration for first-time parathyroidectomy in patients with primary hyperparathyroidism.

Design: Retrospective review.

Setting: University tertiary care center.
