Hyper-activated depressor septi nasi is an important factor caused a nasal tip drooping and many studies have been carried out, however it still remains controversial. This study presents a surgical modality for its intervention, based on the anatomical study. Eleven fixed and six fresh cadavers were used for the study. We found that the depressor septi nasi was consisted of three fascicles. Medial fascicles were inserted into the dermocartilaginous ligament, and deep fibers of the medial fascicles were attached to the anterior nasal spine. After superficial fibers were interdigitated with the orbicularis oris, they were attached to the alveolar bone. Intermedial fascicles were inserted to the footplates of the medial cruses and the caudal septum. After they were interdigitated with the medial fascicle and the orbicularis oris, they were attached to the alveolar bone. From April to August 2008, five patients had surgical intervention for hyper-activated depressor septi nasi. Medial and intermedial fascicles were detached completely from the anterior nasal spine and the septum through intranasal approach. Tip droopings were improved in all cases. Specific complications were not found. We believe that surgical intervention through intranasal approach is a useful method for correction of tip drooping.

PURPOSE: We determined the usefulness of in vitro germ cell culture in nonobstructive azoospermic patients diagnosed with Sertoli cell only syndrome, no sperm in testicular sperm extraction. MATERIALS AND METHODS: This study included 44 patients (45 testicular tissues) with nonobstructive azoospermia who were diagnosed with Sertoli cell only syndrome and were found to have no sperm in testicular sperm extraction between January 2006 and July 2008. Among the 45 testicular tissues, 22 tissues were processed for culture. In the in vitro cultures, the testicular tissues were dissociated and plated on gelatin-coated dishes. Patients were divided into 2 groups according to culture success: group I, culture positive (+; n=10); and group II, culture negative (-; n=12). RESULTS: The mean patient ages were 31.73 and 31.68 years for groups I and II, respectively. The mean testicular sizes were 10.19 and 10.42 cc, respectively; the semen volumes were 2.86 and 3.04 cc, respectively; and the mean FSH, LH, and testosterone levels were 18.86 mIU/ml, 5.99 mIU/ml, and 4.46 ng/ml vs. 21.02 mIU/ml, 6.29 mIU/ml, and 4.32 ng/ml for groups I and II, respectively, with no significant differences between the groups (p>0.05). The culture rate of nonobstructive azoospermic patients diagnosed with Sertoli cell only syndrome was 45.5% (10/22). Round spermatid injection was done in 2 patients with consent of the patients, but implantation failed. Among the 45 tissues, germ cells were found in 8 tissues after pathologic reexamination. CONCLUSIONS: The in vitro culture of germ cells would be useful in the advanced treatment of nonobstructive azoospermic patients.

Bilateral fibroepithelial polyps of the ureter are scarcely seen benign mesodermal tumor that occurs most often at the proximal ureter. Most patients present with either hematuria due to necrosis at urethral polyp of flank pain secondary to partial ureteral obstruction. The Diagnosis may be established with intravenous pyelography, retrograde pyelography, ureteroscopy and CT. Local resection is the treatment of choice. We report a case of bilateral fibroepithelial polyps of the ureter with a brief review of literatures.

PURPOSE: Although RV infection is less common in neonate than older infants, because of high transmissibility and morbidity, it is devastating disease in nursery. With experience of RV infection outbreak in our nursery, we report its clinical and epidemiological characteristics. METHODS: From March 2002 to September 2003, 39 neonates were diagnosed with RV infection in nursery by immunochromatographic method. In addition to prevalence time, monthly distribution, and method of blocking outbreak of the disease, demographic, clinical and laboratory data for the neonates were evaluated. RESULTS: After occurring index patient in a nursery of Hanyang University Hospital in Seoul at March 22, 2002, the RV infection was increasing. Although the nursery was disinfected with 99% alcohol, 6 cases of new RV infections developed during July 2002. Eradication of RV infection was achieved after closing the nursery with cohort twice for 17 days and for 10 days. During period of this study, total 39 cases of RV infection were identified and the incidence of infection was 11.5%. Unlike to older infants, the majority of neonatal patient were asymptomatic (47.3%). CONCLUSION: We propose that instead of disinfection using 99% alcohol, long-term isolation with cohort is preferable to control RV transmission in nursery.

Severe acute respiratory distress syndrome (ARDS) is a life-threatening disease with a high mortality rate. Although many therapeutic trials have been performed for improving the mortality of severe ARDS, limited strategies have demonstrated better outcomes. Recently, advanced rescue therapies such as extracorporeal membrane oxygenation (ECMO) made it possible to consider lung transplantation (LTPL) in patients with ARDS, but data is insufficient. We report a 62-year-old man who underwent LTPL due to ARDS with no underlying lung disease. He was admitted to the hospital due to influenza A pneumonia-induced ARDS. Although he was supported by ECMO, he progressively deteriorated. We judged that his lungs were irreversibly damaged and decided he needed to undergo LTPL. Finally, bilateral sequential double-lung transplantation was successfully performed. He has since been alive for three years. Conclusively, we demonstrate that LTPL can be a therapeutic option in patients with severe ARDS refractory to conventional therapies.

PURPOSE: The aim of this study is to evaluate the incidence of hyperkalemia and the contributing factors of nonoliguric hyperkalemia in low birth weight infants within 48 hours after birth. METHODS: The incidence of nonoliguric hyperkalemia and difference of clinical features between hyperkalemia (>6.7 mEq/L) and normokalemia (< or =6.7 mEq/L) groups were determined by reviewing medical records of 196 low birth weight infants who were born in Hanyang university hospital between Oct. 2001. and Jul. 2004. We analized the serum level of sodium, potassium, fluid intake, urine output, pH of blood gas and others. RESULTS: Among 196 infants, 17 infants was hyperkalemia developed in 48 hours after birth. In that cases, 10 infants were showed EKG abnormalities, such as ventricular tachycardia. In all cases, birth weight, gestational age, Apgar score, usage of surfactant, urine output, BUN and creatinine were significant. In A group gestational age, urine output, BUN, creatinin were significant, in B group BUN, creatinine were significant, in C group BUN were significant between hyperkalemia and normokalemia. Six infants with hyperkalemia died as a result of hyperkalemia induced cardiac arrhythmia. CONCLUSION: Hyperkalemia frequently occurred extremely premature infants. But hyperkalemia also be developed in low birth weight infants who were not suffered from asphyxia or tissue damage. Serum potassium level should be monitored to avoid life threatening cardiac arrhythmia in low birth weight infant.

BACKGROUND: Serious organ shortage necessitates ABO incompatible (ABOi) kidney transplantation (KT). Recent reports utilizing rituximab instead of splenectomy and tacrolimus (FK)-based triple immunosuppressants showed excellent graft outcome. METHODS AND RESULTS: Thirteen cases of ABOi living donor KT have been performed since Feb. 2007 in our center. Donor and recipient blood group was B to O (n=5), A1 to O (2), AB to B (2), AB to A1 (1), A1 to B (2) and B to A1 (1). Rituximab was given at 4 weeks before transplantation. Plasmapheresis (PP) was initiated at 7~14 days before transplantation with concurrent immunosuppressants. The number of pretransplant PP was 5.7+/-1.4. Posttransplant PP was also performed in 6 patients with higher initial titer of ABO antibody (IgG > or =256; n=2), rapidly rising antibody titer during the critical period of 2 weeks posttransplantation (n=2), or increase in serum creatinine during the critical period while awaiting pathology report of graft biopsy (n=2). Mean number of posttransplant PP in these 6 patients was 2.2+/-1.3. Median IgG anti-ABO antibody titer before precondition, at transplantation, at 2 weeks and at 6 months was 64 (8~512), 2 (1~8), 2 (1~16) and 6 (1~16), respectively. IgM titer at corresponding time point was 16 (2~128). 1 (1~1), 1 (1~2) and 1.5 (1~4), respectively. Median follow up was 8 (5~27) months. No patient or graft was lost. No patient developed acute humoral rejection. Graft function remained stable with latest serum creatinine 1.2+/-0.3 mg/dl. CONCLUSIONS: ABOi living donor KT without splenectomy can be safely performed with the use of current preconditioning and immunosuppressive regimen, and is therefore a valuable option for expanding donor pool and should be actively performed in Korea.

STUDY DESIGN: A retrospective study OBJECTIVES: To introduce the technique of minimally invasive transforaminal lumbar interbody fusion and examine its clinical and radiologic results. SUMMARY OF LITERATURE REVIEW: Transforaminal lumbar interbody fusion with a mini-incision using a tubular retractor was recently developed. The aim of this procedure is to reduce the approach-related morbidity and achieve better results in an effective and safe manner. MATERIALS AND METHODS: Thirty eight patients were followed up for more than 1 year. Their mean age was 57 years and the mean follow-up was 19 months. The diagnosis was spinal stenosis, spondylolisthesis and recurred herniated nucleus pulposus in 22, 14 and 2 patients, respectively. The Oswestry disability index, intervertebral disc space height, fusion rate and complications were evaluated. RESULTS: The Oswestry disability index improved from 30 points (range, 50~16 points) to 10 points (range, 2-24 points) at the last follow-up. Thirty-four patients (90%) showed excellent or good results. The intervertebral disc space height increased from 8.7 mm to 10.8 mm. Two cases showed nonunion but the clinical results were good. Complications included one case of infectious spondylitis requiring antibiotics, one case of cage dislodgement requiring additional surgery and one case of a pedicle screw malposition showing no clinical symptoms. CONCLUSIONS: Minimally invasive transforaminal lumbar interbody fusion reduced the soft tissue injury and blood loss and shortened the recovery period compared to the traditional open techniques.

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. A 77-year-old man was referred for the evaluation of general weakness and leukocytosis. Computed tomography showed a 9.5×6.5-cm cavitary lesion with an air-fluid level near the stomach, which was thought to be a perigastric abscess. Upper endoscopy revealed a fistula on the greater curvature at the mid body of the stomach. The margin of the fistula opening was clearly demarcated, and yellow turbid fluid oozing from the fistula was seen. Laparoscopic wedge resection was performed at the perforated area of the stomach. Immunohistochemistry revealed CD117 expression. A diagnosis of intermediate-risk GIST was made. No recurrence was identified within 18 months after the operation. The final diagnosis was perforated gastric GIST communicating with the gastric lumen and presenting as an intra-abdominal abscess.
