Syndrome of inappropriate antidiutetic hormone(SIADH) secretion is the most common cause of hyponatremia in clinical medicine. Before diagnosis of the SIADH is made, other causes for a decreased diluting capacity and nonosmotic stimuli for AVP release need to be rule out. Disorders associated with SIADH can be divided into 4 major etiologic groups: malignancies, pulmonary diseases, central nervous disorders, and drugs. A 45-year-old woman was admitted due to maculopapular skin eruption and fever after taking medications for fever and myalgia. Generalized tonic clonic seizure was developed nine days later, and laboratory results showed marked hyponatremia. During the evaluation, treatment, and subsequent follow-up, the diagnosis of SIADH was confirmed, but the definitive cause was obscure. With fluid restriction, sodium replacement and demeclocycline therapy, she recovered completely 6 months later. We suggest that the SIADH might be related to drug-induced generalized maculopapular rash via menmgitis-like reaction in CSF as one of systemic adverse side effects to drugs rather than direct effect of related drugs.

BACKGROUND: Carolic restriction as a treatment for obesity causes catabolism of body protein stores and produces negative nitrogen balance. GH administration causes acceleration of lipolysis and promotion of nitrogen conservation. We evaluated the effects of GH treatment and caloric restriction on lipolysis, anabolic effects and body composition in obese subjects. METHODS: 24 obese (20% over IBW) subjects (22 women and 2 men; 22-46yr old) were fed a diet of 25kcal/kg IBW with 1.2g protein/kg IBW daily during treatment. The subjects were assigned at random to either treatment with recombinent human GH (n=12, 0.06U/kg IBW every other day) or placebo (n 12, vehicle injection) for 12 weeks. Body fat was assessed by impedence and abdominal fat, visceral fat area at the umbilicus level and muscle area of mid thigh level were measured using computed tomography. RESULTS: Fraction of body weight lost as fat lost was significantly greater in GH treatment than in placebo group (1.21+-0.48%/kg, vs 0.52+-0.28%/kg, p0.05). GH treatment caused significant decrease in visceral fat area (35.3% vs 28.5%, p<0.05). In placebo group, there were significant loss of muscle area (-4.8 +-2.6cm ) and lean body mass (-2.62 +-1.51kg) after treatment. In contrast, GH treatment group had more increase in muscle area (3.5+-2.3cm ) and lean body mass (1.13 +-1.04kg) and positive nitrogen balance (1.81+-4.06g/day). GH injections cuased a 1.6-fold increase in IGF-I, despite caloric restriction. GH responses to L-dopa stimulation were blunted in all subjects and GH responses were increased after treatment. Both group showed hyperinsulinemia during oral glucose tolerance test (OGTT), and after treatment, they had decreased in insulin secretion. However, GH treatmnent group had not significant decrease, because GH might induce insulin resistance. FFA response areas during OGTT markedly decreased after treatment in both group. In GH treatment group, more decrease of FFA responses might result from the antilipolytic effect by higher level of insulin or more decrease in amount of fat. CONCLUSION: This study has demonstrated that in obese subjects fed hypocaloric diet, GH accelerates body fat loss and exerts anabolic effects.

Diabetic insipidus may first present before, during or immediately after pregnancy. Pregnancy serves as a physiologic provocation test that unmasks latent diabetes insipidus. It may explain the very rare first occurrence of diabetes insipidus in the pureperium. Central diabetes insipidus occurring after delivery associated with a catastrophic delivery and postpartum hypopituitarism is more frequent entity. We recently experienced central diabetes insipidus patient, aggrevated polyuria and polydipsia after total hysterectomy due to cervical carcinoma, who had interesting past history of severe polyuria and polydipsia developed during puerperium of 1st pregnancy, 14 years ago. She have had quiet normal pregnancy and there was no definite postpartum complication of pregnancy at that time. There were no change of polyuria and polydipsia during and after second pregnancy and 2 another pregnancy terminated artificially compare to puerperium of 1st delivery. She has intact anterior pituitary gland functinally and anatomically, but the posterior pituitary hyperintense signal with pre-enhance Tl-weighted imaging was absent on MRI.

BACKGROUND: Prenatal tongue development may affect oral-craniofacial structures, but this muscular organ has rarely been investigated. METHODS: In order to document the physiology of prenatal tongue growth, we histologically examined the facial and cranial base structures of 56 embryos and 106 fetuses. RESULTS: In Streeter's stages 13-14 (fertilization age [FA], 28 to 32 days), the tongue protruded into the stomodeal cavity from the retrohyoid space to the cartilaginous mesenchyme of the primitive cranial base, and in Streeter's stage 15 (FA, 33 to 36 days), the tongue rapidly swelled and compressed the cranial base to initiate spheno-occipital synchondrosis and continued to swell laterally to occupy most of the stomodeal cavity in Streeter's stage 16-17 (FA, 37 to 43 days). In Streeter's stage 18-20 (FA, 44 to 51 days), the tongue was vertically positioned and filled the posterior nasopharyngeal space. As the growth of the mandible and maxilla advanced, the tongue was pulled down and protruded anteriorly to form the linguomandibular complex. Angulation between the anterior cranial base (ACB) and the posterior cranial base (PCB) was formed by the emerging tongue at FA 4 weeks and became constant at approximately 124degrees-126degrees from FA 6 weeks until birth, which was consistent with angulations measured on adult cephalograms. CONCLUSIONS: The early clockwise growth of the ACB to the maxillary plane became harmonious with the counter-clockwise growth of the PCB to the tongue axis during the early prenatal period. These observations suggest that human embryonic tongue growth affects ACB and PCB angulation, stimulates maxillary growth, and induces mandibular movement to achieve the essential functions of oral and maxillofacial structures.

Hashimotos thyroiditis has been associated with a various autoimmune disorders. The immunologic mechanisms involved in the pathogenesis of these disorders have not always been thought to be the same. Although it was demonstrated that there were high prevalence of abnormal thyroid function and autoantibody in autoimmune hemolytic anemia(AIHA) and Fisher-Evans syndrome(FES), AIHA combined with Hashimotos thyroiditis is rare in Korean literature. It was suggested that a common immunologic mechanism may be involved in the pathogenesis of both disease and the possibility of multiple autoimmune syndrome might present in autoimmune hematologic disorders. We experienced a 74-year old woman with a 12-year history of a hypothyroidism due to Hashimotos thyroiditis was hospitalized with sudden development of warm AIHA with positive Direct & Indirect Coombs test and pericardial effusion. Her thyroid function test showed subclinical hypothyroidism with the maintenance dosage of levothyroxine(100pg/day). With glucocorticoid and plasmapheresis, AIHA and pericardial effusion were corrected successfully. It is suggested that the prudent immunologic study is needed for the anemia developed in patients with Hashimotos thyroiditis with or without hypothyroidism.

PURPOSE: To evaluate the magnetic resonance imaging (MRI) and clinicopathological features of triple negative breast cancer, and compare them with those of non-triple negative breast cancer. MATERIALS AND METHODS: This study included 231 pathologically confirmed breast cancers from January 2007 to May 2008. We retrospectively reviewed the MRI findings according to the Breast Imaging Reporting and Data System (BI-RADS) lexicon: mass or non-mass type, mass shape, mass margin, non-mass distribution, and enhancement pattern. Histologic type, histologic grade, and the results for epidermal growth factor receptor, p53, and Ki 67 were reviewed. RESULTS: Of 231 patients, 43(18.6%) were triple negative breast cancer. Forty triple negative breast cancers (93.0%) were mass-type lesion on MRI. A round or oval or lobular shape (p=0.006) and rim enhancement (p=0.004) were significantly more in triple negative breast cancer than non-triple negative breast cancer. In contrast, irregular shape (p=0.006) and spiculated margins (p=0.032) were significantly more in non-triple negative breast cancer. Old age (p=0.019), high histologic grade (p<0.0001), EGFR positivity (p<0.0001), p53 overexpression (p=0.038), and Ki 67 expression (<0.0001) were significantly associated with the triple negative breast cancer. CONCLUSION: MRI finding may be helpful for differentiation between triple negative and non-triple negative breast cancer.

The Alstrom syndrome is inherited autosomal recessive disorder, characterized by obesity, diabetes mellitus, pigmentary retinal degeneration, normal intelligence, sensorineural hearing loss, baldness, acanthosis nigricans, male hypogonadism, hyperuricemia and hypertriglyceridemia. There is no reported case of Alstrom syndrome in Korea yet. We experienced a 29-year-old female patient with clinical characteristics similar to Alstrom syndrome who was admitted due to poorly controlled diabetes mellitus and diabetic retinopathy with hemorrhage. We report this case with the review of literatures.
