Approach to failed spinal anaesthesia for caesarean section.

Failure of spinal anaesthesia for caesarean section may have deleterious consequences for the mother as well as the newborn baby. In this article, we discuss the mechanisms of failure of spinal anaesthesia as well as the approach to a failed block. We performed a literature search in Google Scholar, PubMed, and Cochrane databases for original and review articles concerning failed spinal anaesthesia and caesarean section. Strategies for a failed spinal anaesthetic include manoeuvers to salvage the block, repeating the block, epidural anaesthesia or a combined spinal-epidural (CSE) technique, or resorting to general anaesthesia. Factors influencing the choice of these alternative options are discussed. A "failed spinal algorithm" can guide the anaesthesiologist and help reduce morbidity and mortality.

Van Wyk Grumbach Syndrome: A Rare Consequence of Hypothyroidism.

Long standing hypothyroidism presenting as an ovarian mass has been well described in literature as the Van Wyk Grumbach syndrome (hypothyroidism, isosexual precocious puberty and ovarian mass). Here, authors report this entity in a 11 y 7 mo old girl child who was referred to a surgeon in view of intestinal obstruction along with a multiloculated ovarian cyst. On evaluation, she was found to have raised serum creatinine, short stature, delayed bone age and pituitary enlargement. She was diagnosed with autoimmune thyroiditis and was started on replacement therapy with thyroxine, after which the ovarian cysts regressed. This entity should be kept in mind in cases of ovarian cysts, especially those with isosexual precocity, to prevent unnecessary evaluation and surgical misadventures.

Preliminary results of VATS thymectomy for pediatric myasthenia gravis.

Myasthenia gravis (MG) is a debilitating disease which necessitates long-term medical therapy. If left untreated, it can have a high mortality rate. The commonest variety in children, the autoimmune variety, often requires recourse to immunomodulation including prolonged usage of high-dose steroids. Thymectomy has not been a popular option among treating clinicians. There is evidence to suggest that if thymectomy is performed early in the disease, it has a high success rate in reducing the doses of the oral steroid medication and also in inducing remission of the disease. We have performed video-assisted thoracoscopic surgery (VATS) thymectomy in four patients with the autoimmune variety of MG. In this study, we have had a fair and comparable success rate as with the other adult series. On the basis of this preliminary study, we recommend that the option of VATS thymectomy should be offered to select patients of MG.

Omental torsion.

Omental torsion is a rare cause of acute abdominal pain, and clinically mimics acute appendicitis. A 11-year-old boy presented with symptoms and signs suggestive of appendicitis. A computed tomography of abdomen revealed findings suggestive of omental torsion. Diagnostic laparoscopy confirmed the diagnosis of torsion of a segment of the greater omentum.
