Peutz-Jeghers syndrome is an autosomal dominant inherited disorder characterized by multiple gastrointestinal hamartomatous polyps and mucocutaneous pigmentation. Peutz-Jeghers syndrome has an incidence of approximately 1 in 25,000 to 300,000 births. Crohn`s disease is a chronic inflammatory bowel disease that typically manifests as regional enteritis with its incidence ranging from 3.1 to 14.6 cases per 100,000 person-years in North America. Herein, we report a case of a 30-year-old male patient who had both Peutz-Jeghers syndrome and Crohn`s disease. We believe that this is the first case in Korea and the second report in the English literatures on Peutz-Jeghers syndrome coincidentally accompanied by Crohn`s disease.

Amyloidosis is a rare disease defined by extracellular deposits of amorphous fibrillar proteins, derived from aggregations of misfolded proteins. Localization of amyloidosis in the gallbladder is uncommon; only eight cases have been reported. We describe a case of amyloidosis diagnosed by cholecystectomy, which possibly also affected the liver and kidney. The patient was misdiagnosed with polymyalgia rheumatica, but after a cholecystectomy to treat chronic cholecystitis, we ultimately diagnosed him with amyloidosis. We review amyloidosis with gallbladder involvement in the literature. (Korean J Gastroenterol 2016;68:49-53)

저자들은 십이지장의 팽대부에서 발견된 종양에 대해 조직검사를 시행, 신경내분비종으로 판단하여 내시경적 유두부 절제술을 시행하였으며 신경절세포 부신경절종으로 진단된 증례를 경험하였으며, 신경절세포 부신경절종이 내시경적 유두부절제술로 성공적으로 치료되었기에 문헌고찰과 더불어 보고하는 바이다. Gangliocytic paraganglioma (GP) is an extremely rare tumor that mostly occurs in the periampullary area of the duodenum. It is characterized by benign behavior and favorable outcomes, but sometimes shows regional lymph node dissemination. GP consist of three characteristic histological components: epithelioid, spindle, and ganglion cells. Therefore, it is often misdiagnosed as a neuroendocrine tumor when only endoscopic forceps biopsy is performed. The clinical management of GP has not yet been standardized. This case report describes an asymptomatic patient who was initially diagnosed with a grade-1 neuroendocrine tumor, but was confirmed as having benign GP after endoscopic papillectomy. Complete en-bloc resection was performed for this patient, without any significant adverse events. At a 6-month follow-up assessment, the patient remained asymptomatic and there was no evidence of recurrence.

본 증례는 9세경 저신장으로 성장호르몬 및 갑상선호르 몬 이상을 진단받고 불규칙하게 치료받았던 과거력이 있는 28세 남자 환자가 성기능 장애에 대한 불안으로 내원하여 뇌하수체 줄기 단절에 의한 시상하부성 뇌하수체 호르몬 이상을 진단받고 사춘기 발현과 생식기능의 유지를 위한 치료를 시행하게 된 1예를 경험하였기에 문헌고찰과 함께 보고 하는 바이다. Functional defects of the pituitary gland are a rare cause of pubertal delay. The pituitary stalk is an important structure that connects the hypothalamus and pituitary gland. A defect in fusion of the pituitary stalk and anterior pituitary gland will block the function of the anterior pituitary gland. A 28-year-old man was referred to our clinic with poorly developed secondary sexual characteristics. He had undeveloped facial, axillary, and pubic hair and was Tanner stage I. Laboratory tests gave random serum testosterone < 0.025 ng/mL, luteinizing hormone (LH) < 0.1 mIU/mL, follicle-stimulating hormone (FSH) 0.626 mIU/mL, thyroid- stimulating hormone (TSH) 6.85 μIU/mL, and fT4 6.96 pmol/L. Sella magnetic resonance imaging (MRI) showed no pituitary stalk enhancement. The response in the combined pituitary function test revealed multiple hormonal defects, while the TSH response to thyrotropin-releasing hormone (TRH) was exaggerated and delayed. Therefore, we concluded that pituitary stalk dysgenesis had led to hypothalamic-type panhypopituitarism. (Korean J Med 2013;85:420-424)

본 연구에서는 몰입형 인간 컴퓨터 상호작용을 위한 햅틱 마우스 시스템을 제작한다. 제작한 햅틱 마우스는 진동감각 뿐 아니라 온열감도 제공하기 때문에 사용자는 더욱 몰입감 있게 가상의 공간을 경험할 수 있다. 진동감각과 온열감을 제공하기 위하여 편심모터들과 솔레노이드, 그리고 펠티어 엑츄에이터를 이용하였으며 제작한 시스템의 평가를 위하여 레이싱 게임 프로토타입을 구현하여 테스트를 수행한다. 실험결과로부터 본 햅틱 마우스는 가상공간에서 사용자에게 사실감을 전달함을 알 수 있다. In this paper, we develop a haptic mouse system for immersive human computer interaction. The proposed haptic mouse system can provide vibrotactile feedback as well as thermal feedback for realistic virtual experience. For vibrotactile and thermal feedback, we use eccentric motors, a solenoid, and a peltier actuator. In order to evaluate the proposed haptic mouse, we implement a racing game prototype system. The experimental result shows that our haptic mouse is expected to be useful in experiencing virtual world.

Lower gastrointestinal bleeding can be caused by various etiologies including hemorrhoids, diverticulitis, neoplasms, and ulcerative colitis. However, a rectal ulcer is rarely caused by lower gastrointestinal bleeding, and an anorectal foreign body is a very rare cause of a rectal ulcer. We report the case of a 48-year-old male patient who presented to the emergency department with massive hematochezia and hypovolemic shock that occurred 5 days after inserting garlic into the rectum for treatment of benign prostate hyperplasia.
