allelotyping in mycosis fungoides and sézary syndrome: common regions of allelic loss identified on 9p, 10q, and 17p.allelotyping studies have been extensively used in a wide variety of malignancies to define chromosomal regions of allelic loss and sites of putative tumor suppressor genes; however, until now this technique has not been used in cutaneous lymphoma. we have analyzed 51 samples from patients with mycosis fungoides and 15 with sézary syndrome using methods to detect loss of heterozygosity. micro satellite markers were selected on 15 chromosomal arms because of their proximity to either known tumor ...200111564174
sympathetic innervation of mammary glands mediates suckling-induced reflex inhibition of milk yield in rats.previous work has shown that physiologic activation of the sympathetic system may inhibit milk yield (me) in rats. thus, adrenal catecholamines (cas) are released by suckling, but it is not known whether such inhibition results also from reflex activation by the same stimulus of neural sympathetics upon the mammary gland. the present experiments were designed to determine whether suckling inhibits me induced by oxytocin (ot) in the urethane-anesthetized lactating rat, and whether such inhibition ...200111564449
elevated tumor lactate concentrations predict for an increased risk of metastases in head-and-neck cancer.hypoxia shifts the balance of cellular energy production toward glycolysis with lactate generation as a by-product. quantitative bioluminescence imaging allows for the quantitation of lactate concentrations in individual tumors. we assessed the relationship between pretreatment tumor lactate concentrations and subsequent development of metastatic disease in patients with newly diagnosed head-and-neck cancer.200111567808
base-of-tongue cancer: survival, function, and quality of life after external-beam irradiation and brachytherapy.base-of-tongue cancer has traditionally been treated by surgical resection followed by radiation therapy. primary radiation therapy with brachytherapy has recently been proposed as an alternative. in a prior analysis, we found that patients with advanced tongue-base cancer treated by total glossectomy and postoperative radiation therapy can be cured while potentially maintaining good quality of life. therefore, we designed the current study to assess survival, function, and quality of life in ou ...200111568569

diagnosis of canine hypothyroidism. perspectives from a testing laboratory.the most common sample received by our endocrine testing laboratory is submitted for the diagnosis of hypothyroidism in a dog. the current tests most frequently employed in our laboratory for thyroid evaluation in dogs are total t4, free t4 by dialysis, and canine tsh measurement. each test has strengths and weaknesses and suffers from the possibility of both false positive and false negative results. this article provides a working description of each test and an approach to interpretation of r ...200111570134
feline hyperthyroidism. diagnostics and therapeutics.today, hyperthyroid cats are less symptomatic than those 10 or 15 years ago, and early diagnosis impacts the range and severity of the routine clinicopathological abnormalities traditionally associated with this disorder. in addition, a greater range of tests may be required to confirm a diagnosis as cats may be assessed before a serum total t4 concentration exceeds the reference range. curative treatment options may be more desirable in early cases, but renal function may be adversely affected ...200111570135
treatment of severe double spinal cord injuries.this is a case report describing an injury--sustained by a 25-year-old man during a car accident, and characterized by fracture dislocation of the spine at the level of c7 and t4 accompanied by pulmonary contusion. he had an incomplete spinal cord lesion at the level of c7 and a complete lesion at the level of t4 (t4 asia a). imaging of the spine showed three column fractures with ventral spinal cord compression at both levels. discussants of this case comment on the concept of acute treatment o ...200111571662
hemithyroidectomy: long-term effects on parathyroid function--preliminary report.early hypocalcemia after thyroid surgery has frequently been reported, whereas data regarding long-term effects on calcium homeostasis are scarce. we have previously studied patients after hemithyroidectomy with an oral calcium load test and found normal parathyroid hormone (pth) suppression. however, the 1,25-dihydroxyvitamin d concentration was decreased and the phosphate concentration increased, implying parathyroid insufficiency. we therefore proceeded to investigate pth secretion and suppre ...200111571952
preoperative chemoradiation therapy and anal sphincter preservation with locally advanced rectal adenocarcinoma.preoperative irradiation has been used to produce tumor regression and allow complete resection of rectal cancer with a sphincter-saving procedure. to evaluate the associated toxicity, the response in the primary tumor, and the postsurgical morbidity in a group of patients with locally advanced rectal cancer treated with preoperative chemoradiation therapy and low anterior resection, 120 patients were treated with 45 gy of preoperative radiotherapy and a bolus infusion of 5-fluorouracil 450 mg/m ...200111571965
parotid gland carcinoma: surgical strategy based on local risk factors.to evaluate the best surgical strategy in cases of parotid gland carcinoma, local risk factors (t, n, histology, and treatment) were analyzed in a series of 134 patients. the efficacy of the facial nerve sacrifice in case of macroscopic tumor infiltration was tested by means of survival analyses (kaplan-meier and cox algorithms). this study demonstrated that nerve preservation resulted in a better prognostic value when compared with resection only in the group of patients having a t1 or t2. in p ...200111572247
thyroid function and aging: gender-related differences.the effects of aging on human or animal thyroid function are still not well defined. we evaluated some aspects of thyroid function during aging using an animal model (young and old dutch-miranda rats). in old rats of both genders, serum thyroxine (t4) decreased but serum thyrotrophin (tsh) remained unaltered, suggesting a disturbance in the pituitary-thyroid feedback mechanism during aging. serum tri-iodothyronine (t3) only decreased in old males, possibly because female rats are almost twice as ...200111572803
