A consensus of current surgical practice favors external skeletal fixation in the patients with open fractures, where it can be difficult to achieve a good position and fixation by the usual methods and ipsilateral multiple fractures where it is desirable to avoid prolonged immobilization of adjacent joints. From March, 1979 to December, 1981, 34 patients with lower limb fractures were treated by the method of external skeletal fixator. 22 patients had open comminuted fractures with extensive soft tissue injuries and 12 patients had multiple fractures which were difficult to reduce and maintain in alignment. In the 30 patients which could be assessed, the final result was excellent or good in 23 patients, acceptable in 5 patients, and poor in 2 patients.

Thyrotoxicosis (thyroid crisis) is a known cause of sudden death; however, only a few cases of death resulting from thyrotoxicosis have been reported. Histopathologic examination and postmortem thyroid function tests may be helpful in postmortem diagnosis, but their usefulness seems to be limited. We report three autopsy cases associated with thyrotoxicosis.

BACKGROUND: Specified clinical observations regarding skin changes in viral hepatitis have not yet been accomplished in Korea, especially in view of serotypes. OBJECTIVE: This study was conducted to identify various cutaneous manifestations of viral hepatitis according to viral serotypes and the stages of the disease. METHODS: We performed a clinical observation of cutaneous manifestations in 450 patients who were diagnosed with viral hepatitis. RESULTS: 1. Cutaneous manifestations were found in 383(85.1%) patients. Patients with a longer duration seemed to have skin lesions more frequently. 2. The frequency of cutaneous manifestations was highest in HAV(94.4%) and HBV(84.9%) serotypes. The most common cutaneous manifestation was pruritus(32.4%) in all studied subjects. In HBV hepatitic patients, the most common cutaneous manifestation was pruritus(35.4%), in HCV hepatitic patients, vasculitic purpura(74.5%), in HAV hepatitic patients, urticaria(88.8%), in the hepatitic patients with the mixed form, spider angioma(30.2%) and vasculitic purpura(30.2%). 3. Urticarial lesions in non-HCV hepatitis were of the lymphocytic vasculitis type but HCV hepatitis was associated with neutrophilic vasculitis. The purpuric lesions with HCV hepatitis were of the neutrophilic vasculitis type while lymphocytic vasculitis was present in non-HCV hepatitis. 4. The most severe pruritus was present in HBV hepatitic patients. CONCLUSION: The cutaneous manifestations in viral hepatitis have different clinical features depending on the viral types.

This study was performed to investigate clinical and histopathologic features of steroid acne, which was induced by systemic administration and topical application of corticosteroids. Thirty five cases of steroid acne visited to Department of Dermatology, Hangang Sacred Heart Hospital from September, 1g79 to June, 1984 were analyzed, and the results obtained can be summarized as follows: 1. The peak age of the subjects was third decade(42.9%) with an average age of 30. 1 years, and male to female ratio was l.9: 1,2. The skin lesions had unique clinical features that showed many, uniform sized, erythematous papules and pust;ules. 3 The predilection sites of steroid acne induced by systemic steroid therapy were anterior chest(93.1%), back(44,8%), neck(31.0%), shoulder(31.0%) and face (20.7%) 4 Among thirty five cases of steroid acne, twenty cases were induced by parenteral adrninistration of dexamethasone disodium phosphate(group A), nine cases by oral administration of prednisolone(group B), and six cases by topical application of three kinds of steroid creams(group C). 5. The mean induction time after starting steroid in group A(ll. 3 days) was shorter than those in group B and C(18.9 days and l4.8 days respective)y). The mean total dosage of used steroid in group A was 191. 3mg of dexamethasone disodium phosphate and that in group B was 515. 7mg of prednisolone. On histopathologic findings of twenty two skin biopsy specimens of the three groups, perivascular inflammatory reaction was the most common finding followed by intra-and peri-follicular inflammatory reaction, dermal vascular dilatation, necrosis of follicular epithelium, comedo, intraand periollicular abscess and rupture of follicle.

The aim of the present study is to demonstrate the usefulness of intraoperative fine needle aspiration (FNA) of pancreatic lesions in 30 patients. A conclusive diagnosis was done in 27 patients and the diagnoses of three patients were deferred. No complications followed the procedure. Based on histologic findings of the resected specimens in 20 cases and of cell blocks in 10 cases, the final diagnoses were adenocarcinoma in 19 cases, chronic pancreatitis in nine cases and tuberculosis in two cases. The sensitivity, specificity and diagnostic accuracy were 95%, 100% and 96% resepectively and there were no false positives. The smear of aspirate was stained with toluidine blue and examined by light microscope. The presence of there-dimensional clusters of disoriented cells and the increased nuclear/cytoplasmic ratio with large prominent nucleoli were the most helpful criteria for a diagnosis of malignancy in the pancreas. The intraoperative FNA of pancreatic lesions was considered as a simple, safe, and highly specific and sensitive tool in differentiating benign from malignant lesions. The intraoperative FNA can be recommended as the first tool of choice of intraoperative diagnostic procedure in lesions of the pancreas.

BACKGROUND: Hypertrophic scars and keloids have been regarded as representative of the proliferative change of the connective tissue of the dermis. Clinically, postburn and surgical scars show a smooth, shiny, erythematous appearance at an early stage. It is readily conceivable that, in such scars, changes may take place not only in the dermis but also in the epidermis and, possibly in the stratum corneum (SC). However, in contrast to the tremendous number of studies of scars on the dermis, those studies focusing on the epidermis and the SC have been scarce. OBJECTIVE: We have focused on the function of the SC covering the post-burn scar tissue and keloids. METHODS: Using noninvasive bioengineering measurements of functional properties of the SC, such as transepidermal water loss(TEWL), we evaluated the SC barrier function in various types of healing wounds, such as early erythematous lesion, hypertrophic scar, keloid, healed atrophic scar, scar occurring at the recipient site of the skin grafts and the adjacent normal appearing skin for control. RESULTS: 1. The TEWL values were 14.9+/-7.3 in early erythematous lesions, 13.2+/-7.5 in hypertrophic scars, 10.2+/-5.8 in keloids, 5.6+/-1.3 in healed atrophic scars, 6.9+/-4.3 in scars occurring at the recipient site of the skin grafts. Significantly increased TEWL values were found in all individual lesions(p>0.01) except for the scars occurring at the recipient site of the skin grafts(p<0.05) compared with the corresponding normal control skin. 2. When we randomly compared early erythematous lesions, hypertrophic scars, kelids, atrophic
