Thyroid disease in Nepal before the earthquake [Meeting Abstract]

Greene, L
Before the earthquake, Nepal was one of the poorest nations in the world, with 26.5% of its population, or 190 million people suffering from disorders due to iodine deficiency. Glaciation erosion depletes iodine and selenium in soil, leading to deficient iodine in plants and animals. Goats often have large goiters. Selenium deficiency, impairs T4 to T3 conversion and iodine conservation. Water from wells contaminated with toxins including arsenic, mercury and strontium, also contribute to thyroid disease. Iodine deficiency contributes to high rates of pregnancy loss, preterm labor, stillbirth, and neonatal goiter. Nepalese have some of the largest goiters. While neurological cretinism is more common in the world, goitrous cretinism is more common in Himalayan countries such as Nepal. The highest prevalence of thyroid disease is seen in the subjects over the age of 50. Hypothyroidism occurs in 18% of people in some regions of Nepal. Also, hyperthyroidism is more common, occurring in almost 14% of some regions of Nepal. Some studies report that hyperthyroidism is almost as common as hypothyroidism. Most goitrous subjects were euthyroid (58.59%); hyperthyroidism affected (27.38%). Though women still have more thyroid disease than men, the percentage difference is not as great as in other areas of the world. One researcher reported similar prevalence of subclinical hypothyroidism in women and men, alluding to a dominant effect of iodine deficiency being more important than autoimmunity. Men and women with goiters had a similar prevalence of thyroid dysfunction. Iodine deficiency affects iodination. Goats in Nepal show higher MIT/DIT and T3 /T4 ratios. Water contaminants contribute to thyroid disease. Mercury acts as a selenium antagonist. Arsenic interferes with TR binding, transcription, and signaling and increases risk of simple diffuse goiter. Decreasing thyroid disease in Nepal, includes not only supplementation with iodine, but also supplementation with selenium. In addition, avoiding contaminated well water, by using rain water and installing plumbing, is important for improving general health including thyroid disease

Ethics in Osteoporosis and Osteopenia: The Bare Bones of a Surrogate Marker

Greene, Loren Wissner
First you have a drug, and then you create the perception of need. The diagnosis of osteoporosis determined by bone density testing was promoted in 1995, simultaneously, and not coincidentally, with the FDA approval of the first major drug indicated for osteoporosis treatment. The use of bone density criteria greatly expanded the number of people who might be "diagnosed" to have osteoporosis or low bone density (commonly called "osteopenia") and therefore "eligible" for, or even requiring, medication to treat or prevent osteoporosis. Osteoporosis is a true medical syndrome, but does this make low bone mineral density measurement (BMD) the equivalent? BMD is a surrogate for fracture risk, but it does not have as good a predictive value as other indicators, especially previous fracture or even advanced age. BMD improvement became a standard measure of drug efficacy in many clinical trials rather than the prevention of fracture, the true important outcome. Marketing to and by the medical community, as well as to prospective "patients", has created a huge medical market for a disease that followed the creation of new drugs.

Differentiating radiation (131I) sialadenitis from autoimmune (Sjogren's syndrome) sialadenitis: Case report [Meeting Abstract]

Mandel L.; Greene L.W.
131-I is actively secreted by the salivary glands,causing obstructive symptomatology and hyposalivation. Low dose 131I rarely causes dry mouth but commonly causes post-meal obstructive swelling. Dry mouth in a patient treated with 131-I was due to existing secondary Sjogren's syndrome (SS) exacerbated by RAI. Scintographic, serologic, microscopic findings confirmed secondary SS. Salivary glands concentrate and secrete Technetium-99m pertechnetate (TPT). TPT time/activity scintiscan examines activity of 4 major salivary glands in real-time, distinguishing salivary symptomatology post-131-I from SS. Ductal wall inflammation and blockage following low dose 131-I; scintiscan shows adequate pickup of TPT, but failure to secrete. In contrast, SS causes lymphocytic replacement of entire parenchyma, interfering with acinar cell pickup; scan shows minimal parotid activity. A thyroid cancer patient treated with 131-I showed no parotid activity, pickup or secretion of TPT, but normal submandibular TPT concentration and secretion. Total parotid parenchymal destruction with hyposalivation is more consistent with SS, rather than 131-I effects. Labial microscopy showed focus score = 1 (Chisholm grade 3) lymphocytic clumped foci, consistent with SS. 131-I sialadenitis (Graph presented) causes diffuse lymphocytic distribution. Schirmer test: normal bilateral tear production. Differentiation of dry mouth of autoimmune from radiation sialadenitis is shown by TPT scan. Usually > 150 mCi is required for hyposalivation, and drying effect is not total. Total parotid parenchymal destruction with hyposalivation is more consistent with SS diagnosis

Adrenal insufficiency after laparoscopic hysterectomy in a patient with primary antiphospholipid syndrome [Case Report]

Dierking, E; Gogoi, R; Adamcik, S; Greene, L W; Curtin, J P
BACKGROUND: We report a case of bilateral adrenal hemorrhage and subsequent adrenal insufficiency after a laparoscopic hysterectomy in a patient with anticardiolipin antibody syndrome. CASE: A 55-year-old woman with a history of anticardiolipin antibody syndrome presented with nausea and vomiting 1 week after laparoscopic hysterectomy and staging for endometrial adenocarcinoma. Based on a diagnosis of adrenal insufficiency, the patient was started on oral hydrocortisone 20 mg in the morning and 10 mg in the afternoon, and fludrocortisone 0.05 mg twice daily on day 5. Her symptoms resolved completely within 24 hours of beginning steroids. CONCLUSION: The diagnosis of adrenal insufficiency should be entertained in any patient with a history of thrombophilias presenting with general abdominal complaints

Octreotide therapy for recurrent refractory hypoglycemia due to sulfonylurea in diabetes-related kidney failure [Case Report]

Gonzalez, Rita R; Zweig, Susan; Rao, Jyoti; Block, Romy; Greene, Loren W
OBJECTIVE: To describe a patient with kidney insufficiency from diabetes treated with glyburide, who presented with prolonged and recurrent hypoglycemia unresponsive to large intravenous doses of glucose, which was treated successfully with intravenously administered octreotide, and to review the therapeutic options for hypoglycemia. METHODS: We present a case report of a 66-year-old man with diabetes causing chronic kidney disease, who was treated with orally administered glyburide, 7.5 mg twice a day. He initially presented to another hospital because of hypoglycemia and was treated with intravenously administered glucose and discharged. The next day, his family brought him to our emergency department because of recurring low blood glucose levels and symptoms of sweating, fever, and nightmares. Laboratory tests revealed a blood glucose level of 33 mg/dL and a creatinine concentration of 6.2 mg/dL. RESULTS: The patient was treated with a 5% dextrose and, subsequently, a 10% dextrose infusion without any sustained improvement. The blood glucose level remained low despite the additional administration of 3 ampules of 50% dextrose in water. The patient was given a bolus of octreotide (50 mug subcutaneously) 14 hours after his second presentation. He received another 50-mug dose of octreotide 6 hours later. After this bolus, the hypoglycemia resolved, and he no longer required intravenous administration of glucose to maintain euglycemia. CONCLUSION: Patients with diabetes and kidney disease frequently have persistent and difficult-to-treat hypoglycemia, unresponsive to conventional therapy. Octreotide is an effective and safe treatment for patients with refractory hypoglycemia attributable to sulfonylureas
