Angiotensin-converting enzyme (ACE) activity was measured in 10 patients with anorexia nervosa, 6 with hyperthyroid Graves' disease, and 7 with primary hypothyroidism. Patients with anorexia nervosa had a low serum ACE activity (9.8 +/- 2.2 IU/l), as compared to findings in normal subjects (13.4 +/- 3.5 IU/l) (P less than 0.05). Patients with hyperthyroid Graves' disease had high serum ACE activity (23.7 +/- 5.8 IU/l), as compared to levels in normal subjects (P less than 0.01), and patients with primary hypothyroidism tended to have low serum ACE activity (10.1 +/- 1.8 IU/l), compared to the normal subjects (P less than 0.1). Following weight gain (before; 71.3 +/- 10.2% of ideal body weight, after; 88.7 +/- 5.6% of ideal body weight), serum ACE activity in patients with anorexia nervosa reverted to within the normal range (13.8 +/- 3.5 IU/l), and serum T3 concentration was restored to the normal range (before; 0.7 +/- 0.2 ng/ml, after; 1.1 +/- 0.3 ng/ml). In these patients, ACE activity correlated with the per cent of ideal body weight (P less than 0.05). These data suggest that, in underweight subjects with anorexia nervosa, decreased serum ACE activities may relate to emaciation.

A 65-year-old female with general malaise, anorexia and marked emaciation was studied by secretion stimulation tests on 6 anterior pituitary hormones. Only ACTH showed no response and the other 5 hormones responded normally. The basal value of antidiuretic hormone was normal. She was found to be suffered from primary hypothyroidism. Though neither antithyroid antibodies nor other autoantibodies were found, Hashimoto's thyroiditis was confirmed by a thyroid open biopsy. Neoplastic lesions of the hypophysis were ruled out by various X-ray and CT examinations of the sella turcica as well as the brain. The case was concluded to be isolated ACTH deficiency associated with Hashimoto's thyroiditis. The substitution therapy using small doses of adrenocortical hormone and thyroid hormone has kept her well and she has been living normally for these five years.

Eleven adult Basenji dogs with immunoproliferative small intestinal disease (IPSID) were studied. Two items of history related to the digestive tract were characteristic: (i) chronic intractable diarrhea in most dogs, and (ii) progressive emaciation. Anorexia was intermittent in only a few dogs. In addition, skin lesions of various degrees of severity were observed, including alopecia of pinnae and ventrum, hyperpigmentation and hyperkeratosis of pinnae, and necrosis and ulcerations of margins of pinnae. The cause of the skin lesions was not determined; however, hypothyroidism did not appear to contribute to the skin changes. Standard hematologic and serum chemical values were not consistently abnormal. However, a poorly regenerative anemia, mild neutrophilia, and increased aspartate aminotransferase and alanine aminotransferase activities were generally observed in severely affected dogs. The Pelger-Huet anomaly was identified in dog 3. Maldigestion and malabsorption as determined by the N-benzoyl-L-tyrosyl-p-aminobenzoic acid and d-xylose test was documented to varying degrees in dogs with IPSID. Maldigestion was correlated with functional pancreatic exocrine insufficiency. Severe malabsorption was documented in only 3 dogs. Serum gastrin values were evaluated in these dogs because of a prior observation of parietal cell hyperplasia and gastric ulceration. Hypergastrinemia was documented in 3 dogs. Additional studies will be necessary to determine whether an acid hypersecretory state contributes to the pathogenesis of IPSID in Basenjis.

In this report, an extremely rare case of pediatric thyrotropin-secreting pituitary macroadenoma (TSHoma) is described. An 8-year-old boy, complaining of unsteady gait, was suspected of endocrinopathy because of emaciation and muscle weakness of the legs. Endocrinological work-up established a diagnosis of hyperthyroidism due to syndrome of inappropriate secretion of TSH. Magnetic resonance imaging showed a pituitary macroadenoma with suprasellar and sphenoidal extension without cavernous sinus invasion. He underwent an endoscopic endonasal transsphenoidal adenomectory due to the diagnosis of TSHoma. The adenoma was soft and it was totally removed. Histopathological staining confirmed diagnosis of TSHoma. Postoperative evaluation revealed a subnormal level of TSH (from 13-21 to 0.03 micro U/ml), normalization of alpha-subunit (from 10.0 to 0.09 ng/ml), and as a result, hypothyroidism. The boy left the hospital with oral levothyroxine that continued until 12 months of discharge. The present 8-year-old case is the youngest case to the best of our knowledge based on a bibliographical search. Reasons for endocrinological remission following adenomectomy are (1) correct diagnosis without delay: lack of cavernous sinus invasion, (2) soft and non-fibrous adenoma tissue, and (3) endoscopic technique with wide vision and illumination: safe even for a 8-year-old child. Early recognition/detection and pituitary-conserving adenomectomy can cure TSHoma and avoid long-term medical therapy and/or irradiation, which contribute to the best interests of patients with TSHoma.

As anorexia patients always go to the psychiatric clinic, little is concerned about the occurrence of sinus bradycardia in these patients for cardiologists and psychiatrists. The aim of this paper is to discuss the relationship between anorexia and sinus bradycardia, and the feature analysis, differential diagnosis and therapeutic principles of this type of sinus bradycardia. We report a case of sinus bradycardia in an anorexia patient with the clinical manifestations, laboratory exams, auxiliary exams, therapeutic methods, and her prognosis, who was admitted to Peking University Third Hospital recently. The patient was a 19-year-old female, who had the manifestation of anorexia. She lost obvious weight in a short time (about 15 kg in 6 months), and her body mass index was 14.8 kg/m(2). The patient felt apparent palpitation, chest depression and short breath, without dizziness, amaurosis or unconsciousness. Vitals on presentation were notable for hypotension, and bradycardia. The initial exam was significant for emaciation, but without lethargy or lower extremity edema. The electrocardiogram showed sinus bradycardia with her heart rate being 32 beats per minute. The laboratory work -up revealed her normal blood routine, electrolytes and liver function. But in her thyroid function test, the free thyroid (FT) hormones 3 was 0.91 ng/L (2.3-4.2 ng/L),and FT4 was 8.2 ng/L (8.9-18.0 ng/L), which were all lower; yet the thyroid stimulating hormone (TSH) was normal 1.48 IU/mL (0.55-4.78 IU/mL). Ultrasound revealed her normal thyroid. Anorexia is an eating disorder characterized by extremely low body weight, fear of gaining weight or distorted perception of body image, and amenorrhea. Anorexia patients who lose weight apparently in short time enhance the excitability of the parasympathetic nerve, and inhibit the sympathetic nerve which lead to the appearance of sinus bradycardia, and functional abnormalities of multiple systems such as hypothyroidism. But this kind of sinus bradycardia and hypothyroidism have good prognosis. And asymptomatic sinus bradycardia with reversible causes, because of the great prognosis, they do not need special treatment. Multiple medical and psychiatric disciplines were consulted, and then, family care, nutritional support and psychiatric therapy were given, and she did not need thyroid hormone replacement therapy. The patient's overall clinical status improved gradually during her hospital stay and her heart rate was recovered to 55 beats per minute.
