Purpose : Short stature is an important complication that impairs the quality of life in survivors of childhood brain tumors. We studied their final adult height (FAH) to evaluate risk factors for short stature. Methods : We reviewed the medical data of 95 survivors of childhood brain tumors (64 males and 31 females) who had been followed up from 1982 to 2006, reached FAH, and had a more than five year-disease-free survival. Results : Final adult height standard deviation score (FAHTSDS: $mean{\pm}SD$) of the patients was lower than those of general population ($-1.15{\pm}1.72$), HTSDS at diagnosis ($-0.13{\pm}1.57$), and target HTSDS ($-0.49{\pm}0.69$). FAHTSDS of craniopharyngioma patients did not decrease ($0.57{\pm}1.17$), but those of germ cell tumor and medulloblastoma patients were significantly reduced ($-1.20{\pm}1.45$, $-2.70{\pm}1.46$; P<0.05). The patients treated with craniospinal radiation or chemotherapy had lower FAHTSDS ($-1.93{\pm}1.58$, $-2.27{\pm}1.44$; P<0.01). In the spinal irradiation group, the younger the age at diagnosis was, the more the loss of FAH (r=0.442, P<0.01). Growth hormone replacement (GHR) didn't improve FAHTSDS, but starting GHR under 12 years was an independent factor for improving FAH once treatment methods were taken into account (P=0.01). Conclusion : The younger age at diagnosis, spinal radiation and chemotherapy were all important risk factors of height loss, and height gain was expected in patients who received GHR under the age of 12 years. Therefore, regular check-ups of growth and early intervention with growth hormones are needed for high risk groups to improve FAH.

Hormonal replacement therapy (HRT) has been proven for treatment of postmenopausal symptoms such as hot flushes, night sweats and urologic symptoms. HRT became very popular in the 1990's, when there were several reports showing that it also helped with other menopausal complications such as osteoporosis and cardiovascular disease. Recent studies report that the incidence of breast cancer, endometrial cancer, cerebral infarction, coronary artery diseases, deep vein thrombosis and pulmonary thrombembolism could rise after HRT. Among these side effects of HRT, the risk of pulmonary thromboembolism increases 2 to 4 fold after HRT, but can vary with the use of different doses and preparations. Here, we summarize the risk factors and clinical courses for 5 patients who developed pulmonary thromboembolism after postmenopausal HRT.

We report a patient who suffered from bronchiolitis obliterans organizing pneumonia(BOOP) after Ivor Lewis operation for esophageal cancer. The patient presented low grade fever, dry cough and mild dyspnea at day after operation. Chest roentgenograms and chest CT revealed bilateral patchy and infiltrative shadows. The respiratory symptoms worsened and respiratory failure developed with mild elevation of WBC count despite of conservative treatment. An open lung biopsy was done and the biopsy specimen showed bronchiolitis obliterans organizing pneumonia(BOOP). After several weeks of steroid therapy, there were marked clinical, physiological and roentgenographic improvements. Our experience suggests that BOOP may be one of the underlying pathology in a number of patients presenting with ARDS after thoracotomy. Since steroid therapy may improve survival in these patients, thoracic surgeons should heighten their index of suspicion for this entity. Early histologic diagnosis should be considered in patients with treatment-resistant ARDS after thoracotomy.

동물용의약품은 가축질병의 예방 및 치료의 목적으로 이용되어 그동안 우리나라 가축의 질병방제와 사료효율의 증진으로 양축농가의 소득증대와 아울러 축산이 대규모로 발전할 수 있게 하는데 기여한 바가 크다. 그러나 특히 항생제나 합성 항균제의 오남용에 따른 가축의 장내 세균과 병원성 세균의 항생항균제에 대한 내성획득으로 질병치료 효과의 저하, 축산식품을 통하여 이들 제제의 잔류물질이 인체내로 들어가 부작용을 일으키거나 세균의 내성인자가 사람 병원체에 전달되어 사람의 질병치료에 장애요인이 될 수 있는 문제점이 제기되고 있다. 그리고 공중위생전인 측면에서 항생항균제, 호르몬제, 생물학적제제(백신 등), 마취제, 마약류, 등의 요주의동물용의약품을 체계적으로 관리할 필요성이 제기되고 있다. 본 주제에서는 동물용의약품 중 현재 가장 많은 량이 이용되고 있는 항생제를 중심으로 사용실태와 오남용 사례를 살펴보고자 한다.

당뇨병환자에서 발생하는 가장 중요한 급성 합병증인 당뇨병성 케톤산증이나 고삼투성 비케톤성 혼수는 인슐린의 투여를 중단하였거나 감염, 외상 등의 신체적 손상이나 정신적 스트레스에 의하여 인슐린에 대한 길항 호르몬들이 과분비돼 발생한다. 일반적으로 당뇨병성 케톤산증은 인슐린 의존형 당뇨병환자 중 주로 젊은 층에서 자주 나타나며 병의 경과가 빠르게 진행되기 때문에 고삼투압 상태보다는 케톤산혈증이 주요 문제가 된다. 반면에 고삼투압성 비케톤성 혼수는 인슐린 비의존형 당뇨병환자 중 주로 노인층에서 호발하며 병의 경과가 서서히 진행하기 때문에 심한 고혈당 상태로 인한 고삼투압 상태가 주요 문제가 된다. 이와같은 당뇨병의 급성 대사성 합병증들은 치료가 지연되거나 적절한 치료가 행해지지 못했을 때는 예후가 극히 불량하며 사망률 또한 높은 것으로 보고되고 있다. 이에 급성 대사성 합병증 중 당뇨병성 케톤산증의 병인, 진단 및 치료 등을 알아보기로 한다.

The hypothalamo-pituitary-gonadal hormone axis is centrally controlled by a complex regulatory network of excitatory and inhibitory signals, that is dormant during infantile and juvenile periods and activated at puberty. The kisspeptins are the peptide products of the KiSS-1 gene and the endogenous agonists for the G protein-coupled receptor 54(GPR54). Although KiSS-1 was initially discovered as a metastasis suppressor gene, a recent evidence suggests the KiSS-1/GPR54 system is a key regulator of the reproductive system. Yet the actual role of the KiSS-1/GPR54 system in the neuroendocrine control of gonadotropin secretion remains largely unexplored, the system could be the first missing link in the reproductive hormonal axis. Central or peripheral administration of kisspeptin stimulates the hypothalamic-pituitary-gonadal axis, increasing circulating gonadotropin levels in rodents, sheep, monkey and human models. These effects appear likely to be mediated via the hypothalamic GnRH neuron system, although kisspeptins may have direct effects on the anterior pituitary gland. The loss of function mutations of the GPR54(GPR54-/-) have been associated with lack of puberty onset and idiopathic hypogonadotropic hypogonadism(IHH). So kisspeptin infusion may provide a novel mechanism for HPG axis manipulation in disorders of the reproductive system.

Cynanchum wilfordii and Phlomis umbrosa Turcz. are known to contain isoflavone, a representative phytoestrogen. This study was performed to determine whether the extract mixture of C. wilfordii and P. umbrosa Turcz. would induce an estrogenic effect in ovariectomized rats. The extracts were administered to the ovariectomized rats at 30, 60, 120 mg/kg per day for 4 weeks, respectively. They showed no estrogenic effect, which was indicated by the decrease in uterus wall thickness as well as the increase in body weight and the level of cholesterol and triglyceride. The extracts also had no effect on the concentrations of estrogen and growth hormone in the serum. However, the increase in alkaline phosphatase activity, which leads to protection against the bone loss caused by ovariectomy, was noted on administration of the extract. Therefore, it seemed that the extracts of C. wilfordii and P. umbrosa Turcz. had no estrogenic effect in rats.

Purpose: This study examined the effects of the postoperative administration of parathyroid hormone (PTH) on fracture healing in intertrochanteric fractures accompanied by osteoporosis in elderly females. Materials and Methods: Female patients aged 65 years and more who underwent surgery after a diagnosis of intertrochanteric fractures and osteoporosis during the period from July 2013 to December 2017 were included as subjects. The subjects were divided into two groups: PTH-treated group and non-PTH-treated group. The formation time of the first callus, timing of the bridging callus, and time of bony union for both groups were evaluated. Results: In the PTH-treated group, the mean time of the first callus formation, average time of bridging callus, and the average time of bony union were 32, 58, 83 days, respectively, which were significantly shorter than that of the untreated group. Conclusion: PTH, a treatment for osteoporosis, promotes callus formation and the healing process. Therefore it will be helpful in intertrochanteric fractures accompanied by osteoporosis in elderly females.

Background: Radioactive iodine (RAI) therapy and whole-body scanning are the fundamentals of treatment and follow-up of patients with differentiated thyroid cancer. It is generally accepted that a Thyroid-Stimulating Hormone (TSH) level of at least 30 ${\mu}U/ml$ is a prerequisite for the effective use of RAI, and that it requires 4-6 weeks of off-thyroxine to attain these levels. Because thyroxine withdrawal and the consequent hypothyroidism are often poorly tolerated, and occasionally might be hazardous, it is important to be certain that these assumptions are correct. We have measured serial changes in serum TSH after total thyroidectomy or withdrawl of thyroxine in patients with thyroid cancer. Subjects and Methods: Serum TSH levels were measured weekly after thyroidectomy in 10 patients (group A) and after the discontinuation of thyroxine in 12 patients (group B). Symptoms and signs of hypothyroidism were also evaluated weekly by modified Billewicz diagnostic index. Results: By the second week, 78% of group A patients and 17% of group B patients had serum TSH levels ${\geq}30{\mu}U/ml$. By the third week, 89% of group A patients and 90% of group B patients had serum TSH levels ${\geq}30{\mu}U/ml$. By the fourth week, all patients in two groups achieved target TSH levels and there were no overt hypothyroidism. Conclusion: in all patients, serum TSH elevated to the target concentration (${\geq}30{\mu}U/ml$) within 4 weeks without significant manifestation of hypothyroidism. The schedule of RAI administration could be adjusted to fit the needs and circumstances of individual patients with a shorter preparation period than the conventional.
