BACKGROUND: Congenital hypotrichosis is a non-specific, descriptive term for structural abnormalities of hairs showing variable clinical features. We recently have encountered a group of eleven patients exhibiting abnormal hairs showing similar patterns. OBJECTIVES: Our purpose was to clarify the entity of this structural hair disorder. METHODS: Dermatologic examination with routine histopathology, trichograms along with scanning electron-microscopic examination and laboratory studies were undertaken. RESULTS: All cases except one were female, and hair abnormalities had developed at birth or within a year. Diffuse distribution of thin, sparse, soft and hypopigmented hairs were noticed. On hair mounts, four patients showed tapering of roots. The majority of the patients exhibited cuticular changes, as well as pitting and longitudinal axial twisting by scanning electron-microscopic examination; one case demonstrated trichorrhexis nodosa, and another, trans-verse fracture. CONCLUSION: Although our cases bear some similar points with woolly hair, some differences were noted between this type of congenital hypotrichosis and other previously described syndromes.

39 patients with tibial shaft fracture had treated by open reduction and internal fixation with AO DCP and screws applying on the medial surface of the tibia, at the Department of Orthopedic Surgery, Ulsan Dongkang Hospital, from January, 1983 to December, 1985. A clinical study was done on all the 39 cases with the follow-up check over 1 year. In general, because the lateral surface of the tibia is well covered by rich soft tissue, it is popularized to apply the plate on the lateral aspect of the tibia. In our department, we applied the plate on the medial aspect of the tibia, which resulted in mimi-zing soft tissue injuries and, by inserting the screws perpendicular to the surface of the bone, increased stability of the fixation; and therefore resulted in relatively short operation time, relatively low incidences of infection and non-union; but there had been some drawbacks such as focal skin necrosis, hematoma, adhesion after fixatives removal, and cosmetic disfiguring. But there were no problems during the follow up periods. So, this is a recommandable procedure of internal fixation with the plate for the tibial shaft fractures.

BACKGROUND: The occurrence of cutaneous malignant tumors has been increasing worldwide due to changes in various environmental factors. OBJECTIVE: Our study aimed to analyze the overall tendency of clinical characteristics in single-center patients with cutaneous malignant tumors according to sex, age, duration, size, anatomic site, treatment, and concomitant diseases. METHODS: We retrospectively reviewed the medical records and clinical photographs of 319 patients diagnosed with cutaneous malignant tumors (basal cell carcinoma, squamous cell carcinoma, melanoma, lymphoma, Paget's disease, metastatic skin cancer, mycosis fungoides, angiosarcoma, dermatofibrosarcoma protuberans, Kaposi sarcoma, malignant fibrous histiocytoma, Merkel cell carcinoma) and 109 patients diagnosed with premalignant tumors (Bowen's disease) between January 2007 and January 2017. RESULTS: The average annual incidence of malignant cutaneous tumors was 2.4%. In total, 158 males (36.9%) and 270 females (63.1%) were included with a mean age of onset of 66 years. Among the malignant tumors, basal cell carcinoma (30.8%) was the most common, while the incidences of squamous cell carcinoma (18.9%), melanoma (6.3%), and lymphoma (4.4%) were also high. The predominantly involved anatomic sites were the face (67.3%), trunk (11.5%), and legs (10.9%). Most cases involved solitarily existing tumors (77.3%), and pruritus (21.7%) was the most common accompanying symptom. Among the 69.6% of patients who received treatment for their tumors, the most common method was surgical removal. No significant increase in concomitant diseases or environmental factors was detected. CONCLUSION: Our study is meaningful as an overall and recent review of various types of cutaneous malignancies that provides preliminary data for further large-scale nationwide studies.

Neonatal diabetes mellitus (NDM) is defined as hyperglycemia that presents clinical symptoms within the first month of life and requires insulin therapy to maintain euglycemia. The diabetic condition may be transient, permanent, or transient with recurrence later in life. NDM is a rare clinical disorder. Three cases of NDM have been reported in Korea so far. We experienced two cases of NDM in twin brothers who were born with small for gestational ages. Their HLA typings were DR9 and DR14, and insulin autoantibody, islet cell antibody, GAD-reactive autoantibody, and insulin receptor antibody were not found. The genetic analysis with polymorphic DNA markers for chromosome 6 indicated paternal uniparental isodisomy.

Coronary restenosis is still regarded as Achilles' Hill of interventional cardiology despite relentless efforts of many investigators. Recent experimental and clinical studies have suggested that both gamma and beta radiation can be reduce restenosis after angioplasty. Currently, intracoronary brachytherapy for the prevention of restenosis has become a new evolving treatment modality in interventional cardiology. This report discusses a physical aspect of gamma and beta radiation, initial clinical results and delivery systems used in intracoronary brachytherapy. We shall take a brief overview of methods and their advantages in intracoronary brachytherapy. Future work should provide further insight for the best way of treating restenosis.
