Background: Cushing syndrome is characterized by glucose intolerance, cardiovascular disease, and an enhanced systemic inflammatory response caused by chronic exposure to excess cortisol. Eosinopenia is frequently observed in patients with adrenal Cushing syndrome, but the relationship between the eosinophil count in peripheral blood and indicators of glucose level in patients with adrenal Cushing syndrome has not been determined. Methods: A retrospective study was undertaken of the clinical and laboratory findings of 40 patients diagnosed with adrenal Cushing syndrome at Chungnam National University Hospital from January 2006 to December 2016. Clinical characteristics, complete blood cell counts with white blood cell differential, measures of their endocrine function, description of imaging studies, and pathologic findings were obtained from their medical records. Results: Eosinophil composition and count were restored by surgical treatment of all of the patients with adrenal Cushing disease. The eosinophil count was inversely correlated with serum and urine cortisol, glycated hemoglobin, and inflammatory markers in the patients with adrenal Cushing syndrome. Conclusion: Smaller eosinophil populations in patients with adrenal Cushing syndrome tend to be correlated with higher levels of blood sugar and glycated hemoglobin. This study suggests that peripheral blood eosinophil composition or count may be associated with serum glucose levels in patients with adrenal Cushing syndrome.

Purpose: The purpose of this study is to compare the performance of the T1 3D subtraction technique and the conventional 2D dynamic contrast enhancement (DCE) technique in diagnosing Cushing's disease. Materials and Methods: Twelve patients with clinically and biochemically proven Cushing's disease were included in the study. In addition, 23 patients with a Rathke's cleft cyst (RCC) diagnosed on an MRI with normal pituitary hormone levels were included as a control, to prevent non-blinded positive results. Postcontrast T1 3D fast spin echo (FSE) images were acquired after DCE images in 3T MRI and image subtraction of pre- and postcontrast T1 3D FSE images were performed. Inter-observer agreement, interpretation time, multiobserver receiver operating characteristic (ROC), and net benefit analyses were performed to compare 2D DCE and T1 3D subtraction techniques. Results: Inter-observer agreement for a visual scale of contrast enhancement was poor in DCE (${\kappa}=0.57$) and good in T1 3D subtraction images (${\kappa}=0.75$). The time taken for determining contrast-enhancement in pituitary lesions was significantly shorter in the T1 3D subtraction images compared to the DCE sequence (P < 0.05). ROC values demonstrated increased reader confidence range with T1 3D subtraction images (95% confidence interval [CI]: 0.94-1.00) compared with DCE (95% CI: 0.70-0.92) (P < 0.01). The net benefit effect of T1 3D subtraction images over DCE was 0.34 (95% CI: 0.12-0.56). For Cushing's disease, both reviewers misclassified one case as a nonenhancing lesion on the DCE images, while no cases were misclassified on T1 3D subtraction images. Conclusion: The T1 3D subtraction technique shows superior performance for determining the presence of enhancement on pituitary lesions compared with conventional DCE techniques, which may aid in diagnosing Cushing's disease.

Cushing's disease (CD) is a rare illness characterized by chronic hypercortisolism secondary to the overproduction of adrenocorticotropic hormone by a pituitary adenoma, which is associated with a high risk of developing serious complications, such as diabetes mellitus, cardiovascular disease, and emotional disorders. Endoscopic transsphenoidal surgery is performed for the treatment of CD, and was initially preferred over other types of treatments. However, the recurrence after pituitary surgery for CD is a common problem after an initial successful surgery. In microadenomas, the remission rates were higher than those of macroadenoma. This patient had a giant tumor that was greater than 4 cm in length on sella magnetic resonance imaging, and panhypopituitarism was detected using a combined pituitary stimulation test. After transsphenoidal surgery, the patient required temporary hormone replacement for a short period of time. After 1 year, he showed a normal cortisol response on the overnight dexamethasone suppression test and low morning cortisol levels. Therefore, we indicated that the patient was cured of giant macroadenoma with panhypopituitarism before surgery, and thus, reported this case.

Objectives : The authors analyzed the surgical series of Cushing's disease to evaluate the proper treatment policy and to verify the possible prognostic factors. Material and Methods : Of 50 patients diagnosed as Cushing's disease and operated at Department of Neurosurgery of our institute between 1988 and 1999, 48 patients with available medical records were analyzed retrospectively. Mean follow-up period was 48 months(3 to 109 months). Preoperative diagnosis was made after evaluating the patients with multiple-stage endocrinological studies and 31 selective patients were evaluated with inferior petrosal sinus sampling(IPSS). Magnetic resonance imaging(MRI) and/or high resolution computerized tomography(CT) was done in all patients. A total of 51 transsphenoidal adenomectomy(TSA) were performed including 3 revision for initial surgical failure cases. Remission was decided on the basis of both endocrinological criteria and clinical status. Radiation and/or ketoconazole therapy were applied to failed cases. For the verification of prognostic factors, the authors evaluated the statistical significance of multiple variables over remission rate by chi-square test. Result : Sensitivity of IPSS for central localization was 93.5% which was better than that of MRI(87.5%). But for lateralization, it was 72.4% for IPSS versus MRI 90.5%. Success rate of TSA was 82%(42/51) and recurrence rate was 9%(4/48). When including adjuvant treatments for surgically failed cases, overall success rate was 89.6% and all of 3 reoperated cases(TSA) due to recurrence were successful. Significant complication occurred in 7.8%(4/51) after TSA including hypopituitarism, diabetes insipidus, and visual loss. Non-existence of tumor in MRI and prolonged symptom duration(>3 years) were significant prognostic factors. Conclusion : TSA can be considered as initial treatment for Cushing's disease. In surgically failed cases, multiple treatment modality may improve the overall outcome and repeated TSA for recurrent cases seem to provide similar success.

Although there has been a considerable research in psychoneuroendocrinology, particularly in relation to the biology of mood disorders, there has been a paucity of research regarding the effects of psychological factors on endocrine diseases. Of the existing literature, the most research is focused on diabetes mellitus, graves' disease. Especially diabetes appears to be the only endocrine disease that has been the focus of recent research studies. Most of the studies had retrospective designs or several methodological flaw. There has been no consistent results demonstrating that psychological factors affect the onset of diabetes mellitus. Several studies have suggested that psychological factors affect the course of diabetes. A small number of studies showed some evidence that psychological stress was associated with changes in glucose regulation in a subset of diabetic patients. There was also evidence to suggest that some temperament and coping skill influence glycemic control in child, adolescent diabetics. Studies of behavioral or psychosocial intervention on diabetic control have been small and have produced mixed results. There was a few controlled study suggested that stressful life events might be a causal role in Cushing's disease and Graves'disease, but there is no presently sufficient evidence to suggest that psychological factors affect the onset and the course of Cushing's disease and Graves' disease. In future, there is need for a well-designed biopsychosocial research with prospective designs, well defined patient population and control groups to study the relationship between psychological factors and endocrine diseases.

NP-59 신티그라피는 부신피질의 기능장애를 선택적으로 영상화할 수 있는 장점이 있기에 다양한 부신질환의 진단에 적응이 되는바 특히 임상검사와 방사선학적 검사 결과가 서로 상이한 경우 진단에 결정적인 도움을 줄 수 있는 기능 검사법이다. 저자는 이러한 장점을 가지고 있는 NP-59 스캔을 부신질환 환자에서 시행하여 그 결과를 임상자료와 비교하여 부신피질 신티그라피의 유용성을 규명해보고자 이 연구를 시행하였다. 본 연구대상으로서 1990년 3월부터 1996년 12월까지 동아대학교병원 핵의학과에서 NP-59 스캔을 시행한 10명의 환자와 그들의 스캔 11예를 대상으로 하여 병력지에 기재된 임상자료와 스캔판독소견을 후향적으로 비교 분석하였다. 대상환자 중 쿠싱병(2예)과 부신종양에 의한 쿠싱증후군(3예)에서는 진단명과 스캔판독소견이 일치하였다. 부신의 부수종양(2예)에서는 1예는 진단명과 판독소견이 일치하였으나 1예에 있어서는 기능성 종양으로 판독되어 불일치를 보였는데 이는 subclinical Cushin-g's syndrome으로 추정되어 관찰중이다. 임상적으로 는 일차성 알도스테론증과 부신성 조모증이 의심되나 부신 CT 검사상 정상소견을 보인 환자에서 이를 확인하기 위하여 덱사메타존 억제스캔을 시행한 결과 정상소견을 보였고 이들은 각각 본태성 고혈압과 간경화증에 동반된 조모증으로 추정되어 치료 및 경과 관찰중이다. 이상의 결과로 보아 NP-59 신티그라피는 쿠싱증후군의 진단과 원인질환의 감별진단에 매우 유용하였으며 비록 대상수가 작아서 결론 내리기는 어려우나 부수종양에서 스캔소견만으로도 전이성 병변을 제외시킬 수 있으므로 결과적으로는 불필요한 생검을 피할 수 있게 하는 임상적인 유용성을 가지고 있었다.

Objective : We analyzed the clinical and endocrinological results of the transsphenoidal microsurgery for ACTH secreting pituitary adenomas. Marerials and Methods : From October 1995 to August 2000, 18 patients underwent transsphenoidal microsurgery for Cushing's disease. We analyzed the surgical results of 17 patients, one patient who was previously operated from other hospital was excluded. Age of the patients were 18 to 61 years old(mean 37.7), male to female ratio was 1 : 3.3, and follow-up period was 3 to 50 months(mean 20.3). The selection of candidates for transsphenoidal exploration was based on endocrinologic criteria. Magnetic resonance imaging was the preferred radiologic test. Selective inferior petrosal sinus sampling of adrenocorticotropic hormone futher refined the diagnosis when endocrinologic and radiologic procedures were not definitive. Results : Results of the preoperative endocrinological test were : level of serum ACTH 29.4 to $225{\mu}g/dL$(mean $93.88{\mu}g/dL$) ; serum cortisol 11.9 to $47.5{\mu}g/dL$(mean $27.49{\mu}g/dL$) ; 24-hour urine free cortisol 235 to $1019{\mu}g/day$(mean $571.0{\mu}g/day$). Inferior petrosal sinus sampling for ACTH was performed in 11 patients and all were confirmed by Cushing's disease and we could predict the laterality of the tumor in 9 of 11 patients. We performed transsphenoidal selective adenomectomy in 5 patients, adenomectomy and subtotal hypophysectomy in 2 patients, adenomectomy and partial hypophysectomy in 9 patients, and in the remaining one patient, hemihypophysectomy followed by total hypophysectomy due to remission failure. Fifteen of 17 patients(88.2%) showed endocrinological remission. Glucocorticoid replacement therapy was performed in all the patients who showed remission for 1 to 24 months(mean 5.9 months), and 6 patients received steroid over 6 months. Conclusion : We conclude that the direct demonstration of a tumor in the pituitary gland by MRI is the most important and definitive diagnostic tool and the location of a mass should be confirmed with increased level of ACTH by the inferior petrosal sinus sampling. Transsphenoidal microsurgery is effective treatment modality for Cushing's disease and the immediate postoperative evaluation of the surgical resection of the tumor is very important. The patients should show hypocortisolism, decreased, subnormal serum ACTH and cortisol levels and 24-hours urine free cortisol. We performed 18 transsphenoidal microsurgery for Cushing's disease in 17 patients and 15 patients(88.2%) showed endocrinological remission.
