Purpose: This study assessed the results of surgical treatment for Neer type-II and type-V unstable distal clavicle fractures via hybrid fixation with a locking compression plate and finger trap wire. Materials and Methods: From September 2016 to April 2018, 15 patients treated for Neer type-II and type-V unstable distal clavicle fractures using hybrid fixation were analyzed retrospectively. The clinical results were analyzed based on the radiological healing time, range of motion of the shoulder joint, American Shoulder and Elbow Society (ASES) score, and the University of California at Los Angeles (UCLA) shoulder score. Results: The range of motion of the shoulder joint completely recovered to the normal range within 9.2 weeks on average (6−24 weeks). Furthermore, the follow-up of the clinical trial showed excellent results, including an ASES score of 98.5±2.3 and an UCLA score of 34.2±1.3. In addition, fracture union was successfully achieved in all cases, and was identified during week 15 on average. Conclusion For the treatment of unstable distal clavicle fractures, hybrid fixation is a useful surgical method with excellent clinical outcomes through rapid recovery of the range of motion of the shoulder joint after surgery.

Keratoacanthoma is a rapidly growing tumor that has the tendency of spontaneous involution but it may persist for some times, continue to enlarge and may become invasive and destructive. Many modalities are available for the treatment of keratoacanthoma. Although excisional surgery is the treatment of choice, this can result in functional and cosmetic defects when large or strategically located lesions are treated. An effective nonsurgical treatment would be desirable in such cases. We report two cases with unusually large or facial keratoacanthoma treated with intralesional methotrexate. One case showed complete resolution over 6 injections and the other after 2 injections. We suggest that intralesional injection of methotrexate is a simple, effective, safe and inexpensive method for the treatment of large keratoacanthoma.

BACKGROUND: Vibrio(V.) vulnificus is a halophilic, gram-negative bacillus that causes a fatal sepsis in patients with underlying chronic disease such as liver cirrhosis and alcoholic abuse. Because V. vulnificus infection has a fulminant course and high mortality rate, early recognition and rapid diagnosis with prompt therapy are necessary to improve survival rate. OBJECTIVE: The purpose of this study was to develop a new selective medium for rapid identification of V. vulnificus through color change of medium according to pH from patients suspected of having V. vulnificus sepsis. METHODS: Rapid isolation and identification of V. vulnificus can be possible by modifying the component of PNC(5% peptone, 1% NaCl, and 0.08% cellobiose [pH 8.0]) broth medium. From this PNC broth, a basal broth(5% peptone+1% NaCl+cellobiose) was prepared and used to evaluate additional medium supplements(cellobiose concentration [0.08, 0.2, 0.1%], pH [6.8, 7.5, 8.0] and pH indicator dye [bromthymol blue, thymol blue, phenol red, bromcresol purple, crystal violet, cresol red, and neutral red]). To examine the rapid identification and selectivity of this basal medium according to various conditions, V. vulnificus was tested by using saline and normal human blood containing these bacteria(1, 000 bacteria/ml), respectively at 37degrees C. A positive reaction(V. vulnificus growth) appeared as color change. The selectivity and identification capacity of this new broth was tested by using other 6 Vibrio species and 14 strains of other bacteria. RESULTS: Color change appeared only in the medium including bromthymol blue and thymol blue as a pH indicator dye. It was called the basal medium containing blue dyes as PNCB(peptone, NaCl, cellobiose and blue dye) medium. It took an average time of 4.8hr for becoming aware of yellow color change in PNCB broth after cultivating with saline mixed with V. vulnificus and 6hr in PNCB broth after cultivating with blood mixed with V. vulnificus. One Vibrio species and another 3 bacteria produced color change. So we confirmed that the final composition and pH of PNCB broth medium was 5% peptone, 1% NaCl, 0.2% cellobiose, 0.0004% bromthymol blue and 0.0004% thymol blue [pH 7.5] CONCLUSIONS: PNCB broth could be used as a selective and differential medium for rapid isolation and identification of V. vulnificus in patients with V. vulnificus sepsis.

Primary inoculation tuberculosis, also called tuberculosis chancre or tuberculosis primary complex, is the result of direct inoculation of M. tuberculosis in the skin of a host who has not been infected. A 33-year-old laboratory male presents with painless erythematous nodule and central ulcer on the left middle finger for 3 weeks. The skin lesion was developed after he punctured his finger with a needle containing M. tuberculosis. He had no history of tuberculosis. Histopathologic finding showed a wedged shaped abscess mixed with nuclear dust and eosinophils in the epidermis, and inflammatory cell infiltrations and caseation necrosis within the granuloma in the dermis. No bacillus was found in the lesion on AFB stain. We performed polymerase chain reaction with lesional tissue and obtained a positive result. So we diagnosed this case as a primary inoculation tuberculosis, and started antituberculosis medication. After 2 months of treatment, the erythema and ulcer improved. The patient completed a 9 months course of antituberculosis therapy without complication.

Acrodermatitis enteropathica is a rare autosomal recessive disorder affecting early infancy. This syndrome is characterized by acral and periorificial dermatitis, alopecia and intractable diarrhea. Whereas hereditary acrodermatitis enteropathica is caused by mutation affecting intestinal zinc absorption, transient acrodermatitis enteropathica is caused by inadequate supply or malabsorption of zinc in the premature infant. We report a case of transient acrodermatitis enteropathica in a 5-month-old, breast-fed premature infant.

BACKGROUND: Adiponectin is a fat cell-secreted cytokine, which has been reported to improve insulin sensitivity and have antiatherogenic properties. However, it is still unclear whether resistin plays a significant role in the development of insulin resistance in humans. The aim of this study was to investigate the relationship of the adiponectin and resistin concentrations with insulin resistance, metabolic markers and adiposity in healthy and type 2 diabetic subjects. METHODS: Eighty-three type 2 diabetic and 139 healthy subjects were studied. Blood samples were drawn after fasting to determine the fasting plasma glucose, insulin, resistin, adiponectin, total cholesterol, triglyceride and HDL-cholesterol levels. The subcutaneous and visceral fat areas were measured at the umbilical level using computed tomography. RESULTS: The serum adiponectin concentrations were significantly lower in the diabetic(6.7+/-2.3microgram/mL) than in the obese(8.2+/-2.4microgram/mL, P<0.01) and non-obese subjects(9.9+/-4.5microgram/mL, P<0.01). The serum resistin concentrations were Similar between the non-obese, obese and type 2 diabetic subjects. From a multiple regression analysis, the fasting glucose, HDL-cholesterol and HOMA-IR were found to be independent determinants of the log of the adiponectin level in the diabetes group. In healthy subjects, the gender, BMI, HOMA-IR, visceral fat area and HDL-cholesterol were associated with the log of the adiponectin level. However, the log of the resistin level was not associated with the markers of insulin resistance and obesity. CONCLUSION: This study showed that the serum adiponectin concentration was closely related to the insulin resistance marker in both healthy and type 2 diabetic subjects. However, the resistin concentration was not associated with the markers of insulin resistance and/or obesity.

Fibroma of the tendon sheath is a benign soft tissue tumor and this mostly occurs in the distal portion of an extremity. The tumor usually appears as a slow-growing, firm, painless, small nodule in association with tendons and tendon sheaths. Histopathologically, it shows a well-demarcated nodule that consists of haphazardly-arranged, fibroblast-like spindle cells that are embedded in a dense collagenous matrix. A 52-year-old woman presented with a tender, solitary, 2.5x2.0 cm-sized, subcutaneous nodule on the right elbow. The skin biopsy specimen showed that the well-circumscribed tumor contained densely-arranged collagen areas with spindle cells and slit-like vascular channels. We herein report on a rare case of fibroma of a tendon sheath on the right elbow.

Lentigo maligna (LM) is a subtype of melanoma in situ that may become lentigo maligna melanoma. LM is a pigmented lesion that most commonly occurs on sun-exposed skin inthe elderly. Intense exposure to ultraviolet light also accounts for nonmelanotic skin tumors, and particularly basal cell carcinoma (BCC). We herein report on a case of LM and BCC on the right face of a 76-year-old woman. She presented with a longstanding irregular-shaped brown to black pigmented patch on the right infra-orbital area, and a pigmented dome-shaped papule on the right nasolabial fold. The histopathologic findings were consistent with LM and BCC. We performed surgical excisions and there has been no recurrence for 10 months.

BACKGROUND: Nettles, of the plant family Urticae, cause nonimmunologic contact urticaria by stinging hairs. Light application of the leaf or stem to the skin results in the rapid development of a short-lived stinging sensation accompanied by wheal formation and itching. The types of chemical mediators causing the stinging sensation and wheal have not yet been clarified. OBJECTIVE: To investigate stinging and urticating substances causing contact urticaria when the skin is in contact with nettle(Urtica thunbergiana). METHODS: Twenty two volunteers were used for the clinical portion of this investigation. The time to wheal development and the evanescent time of pain and wheal were measured after pricking the forearm skin with nettle trichomes, following the administration of antihistamine, antiserotonin or corticosteroid, respectively or a combination of two, either with or without the application of substance P antagonist(capsaicin cream, 0.025%). Nettle extracts were prepared from dry stems and leaves of Urtica thunbergiana. Histamine, serotonin and substance P(SP) contents of nettle extracts were measured by gas chromatographic mass spectroscopy. RESULTS: After puncture of the skin by trichome of nettle, a stinging sensation developed within a few seconds but disappeared faster at the site where capsaicin cream had been applied than at the nonapplied skin site(p<0.05). The development and evanescent time of wheal were not significantly correlated with the application of capsaicin cream. The evanescent time of pain after pricking the skin with trichome following the administration of antiserotonin was significantly shortened at the nonapplied skin site. Pain disappeared more rapidly at the capsaicin applied site following the administration of antihistamine or antiserotonin than at the nonapplied sites(p<0.05), but not following prednisolone administration. Wheal development was delayed significantly at both the capsaicin applied and nonapplied sites after antihistamine administration(p<0.05). Histamine was detected only in the nettle extract. SP and serotonin were not detected because of their insolubility in solvents. CONCLUSION: These results suggest that wheal-and-flare reaction to nettle stings is due primarily to the histamine and partly to the serotonin and SP introduced by the nettle. SP may be mainly involved and partially involved by serotonin in stinging pain.
