Primary adrenal insufficiency is one of the rare clinical manifestations of antiphospholipid antibody syndrome. The pathogenesis is mainly ascribed to the hemorrhagic infarction secondary to thrombosis. We describe a 19-year-old man who developed symptoms of adrenal insufficiency and then was diagnosed of primary antiphospholipid antibody syndrome, which is the first reported case in adult patients in Korea. The possibility of adrenal failure should be considered in the management of antiphospholipid antibody syndrome and also, when primary adrenal insufficiency is accompanied by no definite etiology, the antiphospholipid antibody syndrome should be considered as a possible etiology.

Staphylococcus lugdunensis is a Gram-positive, coagulase-negative Staphylococcus (CNS) species that is found as a skin commensal and has been implicated in fulminant invasive diseases such as infective endocarditis. S. lugudunensis infections resemble Staphylococcus aureus infections in terms of virulence, tissue destruction and clinical course. Although correct identification and determination of the susceptibility profile are important, some commercial systems may misidentify S. lugdunensis . We report a case of native valve infective endocarditis caused by S. lugdunensis , which was misidentified by the Vitek 2system but identified correctly by 16S ribosomal RNA (rRNA) gene sequencing in a 72-year-old male patient. The patient had multiple vegetations on his mitral valve, and the largest one was found on the posterior mitral valve leaflet. It was 2.5cm in size and hypermobile. Diffuse valvular abscess was also observed. He had persistent bacteremia for appoximately 8 days, which was resolved after immediate surgery and antibiotic therapy. When a patient with severe sepsis syndrome grows S. aureus or CNS other than S. lugdunensis on a commercial automatic culture system, the possibility of S. lugdunensis should be considered and further confirmatory testing such as 16S rRNA sequencing may be very useful.

하영일,조해동,유영락,김남규,정환영 대한신경외과학회 1981 Journal of Korean neurosurgical society Vol.10 No.2

The purpose of this study on the surgical results for lumbar intervertebral disc herniation is to analyze the unique feature of the series which seems to be sufficient to represent Korean patients suffering from these diseases. A total of 812 lumbar discectomies had been performed from May, 1972 to December, 1978 at Hanyang University Hospital. The most outstanding unique feature was the level of the lesion. The L₄-L_(5), interspace was affected in 87.6%. while the most of the other series showed almost same incidence between L₄-L_(5), and L_(5)-S₁, interspaces. The results of this analysis are as follows: 1) The incidence ratio of male to female was 1.3: 1. 2) Most were in the 4th and 5th decade (53.5%). The duration was over one year in 64.6% of cases. 3) Traumatic origin was 37.8% of cases. Post-delivery, convulsive and unknown etiology were 2.2%, 0.7% and 59.3% of cases, respectively. 4) The level of the lesion was predilected at L₄-L_(5) interspace with the incidence of 87.6%, while L_(5)-S₁, interspace was affected in 25.4% of cases. Single lesions were 70.8% and the multiple 29.2% of cases. 5) False positive findings of myelogram were 1.2% of cases. 6) Surgical results were gratifying in 92.3% of cases. 7) The incidence of postoperative complications was 3.3% of cases, which were mainly stitch abscesses. 8) The 7 out of 812 cases were associated with spinal tumors.

저장성 강화 버섯 배지 개발

하영아,김설화,김선영,권나희,제희정,임착한,김경희,김민근,류재산 한국버섯학회 2012 버섯 Vol.16 No.2

우리나라의 버섯 품목별 생산가액은 7,500억원 정도이며 안정적인 수준으로 유지되고 있다. 가장 생산가액이 많은 품목은 표고버섯으로 2,000억원에 달한다. 수출현황을 살펴보면 팽이, 새송이를 위시한 농산버섯이 376억원, 표고버섯, 송이버섯을 비롯한 임산 버섯이 110억원 가량 된다. 2000년대 들어 병버섯업을 중심으로 구조조정이 시작되어 농장들이 대규모화 대형화되었다. 국내의 버섯소비시장이 정체기를 보이자 이들 농가는 가격경쟁력을 바탕으로 새로운 수요를 창출하기 위하여 2000년대말부터 버섯수출이 시작되었는데, 팽이(수출액: 242억)와 새송이(수출액: 109억)가 주를 이루고 있다. 해외수출이 지속적으로 증가추세를 유지하고 있지만, 해외 수출버섯의 소비저변이 확대되지 않고, 긴 수송기간에 의해 신선도가 떨어지는 문제가 발생하여 수출액의 증가세를 가로막고 있는 실정이다. 농가별로 각기 다른 버섯재배방법을 사용하여 생산된 버섯의 저장성이 동일하지 않아 장거리시장 수출에 장애요인이다. 저장성이 강화된 새송이버섯 배지를 개발하고자 먼저 우수한 농장의 버섯배지 조성을 조사하고, 이를 바탕으로 성분중심으로 버섯배지원료별로 혼합비를 설정하여 버섯저장성에 미치는 영향을 조사하였다. 17개의 배지조합으로 버섯을 생산하여 생육특성을 조사하고 5℃저장시 저장일수를 기록하였다. 저장성조사결과 배지16과 17은 38, 35일로 기존의 23일에 비해 15일 18일 연장되었다.

Purpose: Fingertip injuries are the most common hand injuries and may lead to significant disability. Knowledge of fingertip anatomy is mandatory to treat these injuries effectively. All surgical techniques used for coverage of fingertip injuries must be based on the nature of the injury and the patient’s age. Many authors have studied the method of fingertip reconstruction because goals of these treatments should include maintaining length, sensibility, motions, and appearance. The purpose of this study is to evaluate the effect of digital artery perforator flap for fingertip reconstruction without aesthetic and functional problems. Methods: From November 2006 to March 2007, the authors performed fingertip reconstruction on 3 fingers of 3 patients, aged between 41 to 54 years (average age, 47 years) using digital artery perforator flap. Results: All fingers recovered successfully and there were no necrosis of the flap. We followed up 3 cases more than 5 months. Light touch and temperature sensation could be detected in all flaps and the static two-point discrimination test was 8 mm. Conclusion: This flap is an alternative choice for coverage of fingertip defects. This method also takes short time to procedure and to recovery. The digital artery perforator flap has never been reported in Korea, however it is considered as a useful method for treatment of fingertip injury.

Purpose: Distally based superficial sural artery island flap has some disadvantages such as postoperative flap edema, congestion, and partial necrosis of the flap margin. Venous congestion is an area of considerable concern in distally based superficial sural artery fasciocutaneous flap and is one of the main reasons for failure, particularly when a large flap is needed. However, we could decrease these disadvantages by means of venous superdrainage. Methods: From June of 2006 to June of 2007, a total of two patients with soft tissue defects of lower one third of the leg underwent venous supercharging distally based superficial sural artery island flap transfer. The distal pivot point of this flap was designed at septocutaneous perforator from the peroneal artery of the posterolateral septum, which was 5cm above the tip of the lateral malleolus. Briefly, this technique is performed by anastomosing the proximal end of the lesser saphenous vein and collateral vein to any vein in the area of the recipient defect site.Results: No venous congestion was noted in any of the two cases. No other recipient or donor-site complications were observed, except for minor wound dehiscence in one case. In 3 to 6 months follow-up, patients had minor complaints about lack of sensation in the lateral dorsal foot. Conclusion: The peroneal artery perforator is predictable and reliable for the design of a distally based superficial sural artery island flap. Elevation of the venous supercharging flap is safe, easy, and less time consuming. In conclusion, the venous supercharging distally based superficial sural artery island flap offers an alterative to free tissue transfer for reconstruction of the lower extremity.

Purpose: The masserteric space is an important tissue compartment of the face, but a disease in it is difficult to diagnose and treat. The submasseteric abscess is located between the masseter muscle and mandibular ramus with different appearances such as sepsis, infection, or tumor. Especially the common misdiagnosis of submasseteric abscess is acute or chronic parotitis. The purpose of this report is to pay special attention to the possible diagnosis of submasseteric abscess for the symptoms of unilateral cheek swelling and tenderness that accompany marked trismus.Methods: A 11-year-old boy came to our hospital because of facial swelling, tenderness, and trismus in a history of left cheek swelling and toothache. We diagnosed his case as submasseteric abscess by CT scan and surgical intervention was performed. Under general anesthesia, the abscess was opened by the intraoral incision and considerably massive pus was drained. Results: Swelling, tenderness, and trismus became to subside during postoperative 10 days and general condition and vital signs became stable. After 6 months, CT scan showed that both masseteric muscles were symmetric and there was no periosteal reaction of the mandible. Conclusion: In conclusion, submasseteric abscess is a rare infection with the symptoms of cheek tenderness and marked trismus. A detailed medical history and clinical examination of a patient as well as computed tomography(CT) are important tools in the accurate diagnosis and efficient treatment of the submasseteric abscess. Adequate drainage, removal of cause, and antibiotic infusion are the management of choice.
