BACKGROUND Hiccups are an infrequent result of lateral medullary infarction. Their importance may be underestimated and they can cause distress, exhaustion, and aspiration. Hiccups in lateral medullary infarction remain poorly understood OBJECTIVE To evaluate the relation between the lesional loci of lateral medullary infarction and hiccups. METHODS 51 patients with lateral medullary infarc...
We report an unusual case of a young male with cerebellar hemangioblastoma treated previously for medullary carcinoma of thyroid, whose PET/CT scans revealed a constellation of findings that suggested the rare Von Hippel Lindau syndrome. The diagnosis was clinched by confirming the findings on whole body contrast enhanced computed tomography (CECT) and contrast enha...
This study determined the levels of adenosine in the renal medullary interstitium using microdialysis and fluorescence HPLC techniques and examined the role of endogenous adenosine in the control of medullary blood flow and sodium excretion by infusing the specific adenosine receptor antagonists or agonists into the renal medulla of anesthetized Sprague-Dawley rats. Renal cortical and medullary...
AIMS To examine the expression of HLA-DR and beta 2 microglobulin in medullary carcinoma and atypical medullary carcinoma of the breast to determine if the effective presentation of tumour antigens to the immune system can differentiate between these two histopathologically similar entities. METHODS Expression of HLA-DR and beta 2 microglobulin was examined by immunohistochemical methods in f...
The present study was designed to determine whether arginine vasopressin (AVP) can stimulate nitric oxide (NO) production within the renal medulla and thereby modulate renal medullary blood flow. An in vivo microdialysis/NO trapping technique was used to determine changes in medullary interstitial [NO]. AVP (2 ng/kg per minute) was delivered into the renal medullary interstitium and resulted in...
Medullary thyroid cancer accounts for 5%-10% of all thyroid cancers. The majority of medullary thyroid cancers are sporadic, but 20% of cases are a result of a germline mutation in the ret proto-oncogene. Hereditary medullary thyroid cancer can be seen as part of the multiple endocrine neoplasia syndrome type 2A or 2B or as part of familial medullary thyroid cancer. This article discusses the c...
Medullary thyroid carcinoma can arise as a component of multiple endocrine neoplasia (MEN) syndrome which includes adrenal pheochromocytoma. Familial medullary thyroid carcinoma with no association of other components of MEN syndrome is also reported. Epinephrine and norepinephrine excreted in 24 hour urine and/or randomly voided urine were measured for screening of pheochromocytoma in patients...
