Neurocutaneous melanosis is a very rare congenital syndrome characterized by the presence of large or multiple congenital melanocytic nevi and benign or malignant melanotic tumors of the central nervous system. We report herein a case of neurocutaneous melanosis with leptomeningeal melanosis and a malignant melanoma of the right temporal lobe in a 46-year old man. The case is exceptional as regards the late onset of symptoms and death. Even without a malignant melanoma, the symptomatic neurocutaneous melanosis has a fatal course. The syndrome is rare but lethal, so the dermatologist should be aware of this syndrome when evaluating the patients with large or numerous congenital melanocytic nevi so as to watch for the usual signs of increased intracranial pressure and to take prompt palliative measures.

BACKGROUND: For Neer type IIB fracture of distal clavicle with coracoclavicular ligament injury, various surgical treatments have been used in literatures. However, there was no consensus on the optimal treatment. The aim of this study is to report the clinical and radiological results of open reduction and internal fixation of unstable distal clavicle fracture and suture augmentation of disrupted coracoclavicular ligament. METHODS: A prospective study was performed in 23 patients with Neer type IIB distal clavicle fracture in Seoul Medical Center, Eulji Hospital, and National Medical Center. Firstly, suture anchors are inserted in the base of coracoid process and preliminary reduction was achieved by tie-off of three suture limbs around the clavicle. Then, the final fixation was completed with anatomical locking plate. Bony union and the distance between coracoclavicular ligaments were evaluated. Clinical results and complications including stiffness and secondary procedures were evaluated. RESULTS: Bony union was achieved in all cases except one (22 of 23). At mean 14.9 months, no significant difference in the mean coracoclavicular distance was observed compared to uninjured shoulder (8.2 +/- 7.9 mm versus 7.3 +/- 3.4 mm, p=0.14). Pain visual analogue scale, American Shoulder and Elbow Surgeons score, Constant score, and Disabilities of the Arm, Shoulder and Hand score were 0.5, 83.4, 78.5, and 6.2, respectively. Revision surgery was performed in one case of nonunion. Four patients who complained of skin irritation underwent implant removal. CONCLUSIONS: In cases of an unstable distal clavicle fracture with coracoclavicular ligament disruption, satisfactory clinical results were obtained by locking plate fixation and coracoclavicular ligament suture augmentation concurrently.

BACKGROUND: The purpose of this study was to evaluate the angle between the long head of the biceps tendon (LHBT) and the glenoid during arthroscopic surgery and its correlation with biceps subluxation on magnetic resonance imaging (MRI). Furthermore, we evaluated the relationship of this angle with subscapularis tears and biceps pathologies. METHODS: MRI and arthroscopic images of 270 consecutive patients who had undergone arthroscopic surgery were retrospectively evaluated. On MRI, 60 shoulders with biceps subluxation and 210 shoulders without subluxation were identified. On the arthroscopic view from the posterior portal, the angle between the LHBT and the glenoid (biceps-glenoid angle) was measured. The biceps-glenoid angle, tears of the LHBT, degenerative superior labrum anterior to posterior (SLAP) lesions, and presence of a subscapularis tear were compared according to the presence of biceps subluxation on MRI. RESULTS: In the subluxation group, 51 (85%) had a subscapularis tendon tear and all shoulders showed biceps tendon pathologies. In the non-subluxation group, 116 (55.2%) had a subscapularis tendon tear, 125 (60%) had tears in the biceps tendon, and 191 (91%) had degenerative SLAP lesions. The incidences of subscapularis tears (p < 0.001) and biceps pathologies (p < 0.001) showed significant differences. The mean biceps-glenoid angle was 87.0° (standard deviation [SD], 11.4°) in the subluxation group and 90.0° (SD, 9.6°) in the non-subluxation group, showing a statistically significant difference (p = 0.037). CONCLUSIONS: Shoulders with subluxation of the biceps tendon on the preoperative MRI revealed more pathologies in the subscapularis tendon and biceps tendon during arthroscopy. However, the arthroscopically measured biceps-glenoid angle did not have clinical relevance to the determination of subluxation of the LHBT from the bicipital groove.

Total elbow arthroplasty is a common surgical procedure used in the management of advanced rheumatoid arthritis, posttraumatic arthritis, osteoarthritis, and unfixable fracture in elderly patients. Total elbow prostheses have evolved over the years and now include the linked, unlinked, and convertible types. However, long-term complications, including infection, aseptic loosening, instability, and periprosthetic fracture, remain a challenge. Here, we introduce each type of implant and evaluate clinical outcomes and complications by reviewing the previous literature.

Eighty five patients of oral cavity cancer, treated with radiation at the Department of Therapeutic Radiology, Korea Cancer Center Hospital, during the period from March 1985 to September 1990 were analyzed retrospectively. Among 85 patients, 37 patients were treated with radiation only and 48 patients were treated with radiation following surgery And 70 patients received external irradiation only by 60Co with or without electron, the others were 7 patients for external irradiation plus interstitial implantation and 8 patients for external irradiation plus oral cone electron therapy. Primary sites were mobile tongue for 40 patients, mouth floor for 17 patients, palate for 12 patients, gingiva including retromolar trigone for 10 patients, buccal mucosa for 5 patients, and lip for 1 patient. According to pathologic classification, squamous cell carcinoma was the most common (77 patients). According to AJC TNM stage, stage I + II were 28 patients and stage III+IV were 57 patients. Acturial overall survival rate at 3 years was 43.9%, 3 year survival rates were 60.9% for stage I + II, and 23.l% for stage III+IV, respectively. As a prognostic factor, primary T stage was a significant factor (p<0.01). The others, age, location, lymph node metastasis, surgery, radiation dose, and cell differentiation were not statistically significant. Among those factors, radiation plus surgery was more effective than radiation only in T3+T4 or in any N stage although it was not statistically sufficient(p<0.1). From those results, it was conclusive that definitive radiotherapy was more effective than surgery especially in the view of pertainig of anatomical integrity and function in early stage, and radiation plus surgery was considered to be better therapeutic tool in advanced stage.

PURPOSE: Zone I fractures of the fifth metatarsal bone can generally be treated by conservative methods while both surgical and conservative methods are used for zone II fractures. However, the clinical results of conservative treatment have been rarely reported. The purpose of this study is to report the clinical results of conservative treatment for zone I and II nondisplaced fractures. MATERIALS AND METHODS: Between July 2007 and August 2008, consecutive thirty seven patients (38 fractures) with zone I and II fractures of the fifth metatarsal bone were treated with tolerable weight bearing and minimum duration of immobilization based on pain on weight bearing. We evaluated the duration of immobilization, time to clinical and radiographic union, and time to pre-injury activity level. RESULTS: Clinical and radiological union were achieved in all patients without any complications including malunion or nonunion. The mean duration of immobilization was 28.7 days. The mean 33.1 days and 48.9 days were required for clinical union and radiographic union respectively, after the initial injury. The mean time to pre-injury activity level was 4.8 months. CONCLUSION: Our study shows that the acute nondisplaced zone I, II fracture of fifth metatarsal bone can be treated effectively using tolerable weight bearing and minimum duration of immobilization, which is based on the pain on weight bearing.

Living-Related-Liver-Transplantation(LRLT) has been established as a reliable method of treatment for patients with end-stage liver disease when the scarcity of cadaveric organ donor was considered. But the hepatic artery is high at risk in thrombosis(HAT) following LRLT. So microsurgical technique was introduced in anastomosis of hepatic artery. This study was aimed at using microsurgical technique in LRLT and presenting some technical details of the procedures. From December 1994 to November 1997, a sereis of 41 LRLTs on patients with end-stage liver disease was performed with follow-up period of 5 to 40 months(mean,15.6 months). Organs were donated by living-related donors(n=36) and living-nonrelated ones(n=5). Hepatic artery was reconstructed with microsurgical technique by plastic surgeon. All hepatic arteries were patent intraoperatively and postoperatively except one case, which had leakage at anastomosed site on the postoperative fourth day.Hepatic artery is high at risk in thrombosis(HAT) following LRLT due to the caliber discrepancy and technical difficulties. To overcome these risks, microsurgical technique was introduced. The technique has greatly reduced arterial complication. However, there are some difficulties in microsurgery of LRLT, which are somewhat different from those in other microsurgery fields: the first difficulty is to obtain a good operative field and a sufficient view through the microscope. The second one is to overcome arterial caliber discrepancy. And the last is to achieve a stable posture in narrow and deep operating field against the respiratory movement and heartbeat.With the persistent team approach of plastic and general surgeons in the field of LRLT, we could have reduced the HAT and have had better outcome after LRLT.

PURPOSE: The aim of this study is to evaluate the correlation between the location of the plate and the incidence of clavicular hypoesthesia and the clinical features of patients with clavicular hypoesthesia after open reduction and internal fixation of clavicular midshaft fractures. MATERIALS AND METHODS: Seventy-eight patients who underwent open reduction and plate fixation for clavicle midshaft fractures between March 2013 and October 2014 were assessed for eligibility. The total clavicular length (A), the distance to the medial end of the plate from the sternoclavicular joint (B), and the distance to the lateral end of the plate from the sternoclavicular joint (C) were measured. Correlation between the location of the clavicular plate and the incidence of clavicular hypoesthesia was evaluated. In addition, the severity, and recovery of hypoesthesia were evaluated. Patient satisfaction, pain visual analogue scale were evaluated regarding hypoesthesia. RESULTS: The incidence of hypoesthesia was 32.1% (25/78 patients). No correlation was observed with respect to the location of the clavicular plate and the incidence of clavicular hypoesthesia (p=0.666 at the medial end, p=0.369 at the lateral end). Recovery from hypoesthesia was observed in 23 out of 25 patients (p=0.008). Patient satisfaction and pain showed negative correlation with the incidence of hypoesthesia (p=0.002 and p=0.022). CONCLUSION: There was no correlation between clavicular hypoesthesia and the plate location. Although most cases of hypoesthesia were recovered, we should try to avoid hypoesthesia due to the negative 'correlation' with patient satisfaction and pain.

BACKGROUND: Superficial fungal infections are common dermatologic disorders, and causative organisms include dermatophytes, yeasts, and nondermatophyte molds. The data about incidence of fungal pathogens can be used to predict increase in antifungal resistasnce and the adequacy of our current pharmacologic repertoire, and provide insight into future developments. OBJECTIVES: This study aimed to identify epidemiologic features and the various organisms from clinically suspected cases of superficial fungal infection. METHODS: A total 11,656 specimens were collected from clinically suspected tinea corporis, tinea cruris, tinea capitis, tinea faciei, tinea manuum, tinea pedis, and finger and toe onychomycosis among patients of Dermatologic clinic of Asan Medical Center from 1998 through 2002. Clinical and culture studies on these cases were performed. However, attemps to establish the causative organism were not done. RESULTS: The incidence of clinically suspected cases was highest in the fifth to sixth decades. The ratio of male to female was 1.09:1. The incidence of toenail was highest, followed by feet, fingernail, trunk and extremeties, groin, scalp, and face. The positive rate of KOH examination was 49.2% and that of culture was 51.4%. Dermatophytes was the most commoly isolated fungal organisms except fingernail onychomycosis. Trichophyton rubrum was the most prevalent fungal pathogen among them. High incidence of Candida species and Trichosporon species was documented in hands, feet and nails. CONCLUSION: Consideration of the current epidemiologic, clinical and mycologic features in the cutaneous fungal infections is of key importance to investigational efforts, diagnosis, and treatment.
