Fat Embolism is a rare complication of multiple long bone fracture or extensive soft tissue injury. The pathogenesis of fat embolism has been poorly understood and still its definite pathogenesis, diagnosis and treatment were not fully established. Recently fat embolism considered as a post traumatic respiratory failure. Monitoring of blood gas is required for early diagnosis and respiratory supportive treatment with continued minitoring is necessary until resolution. Fifteen cases of fat embolism treated at from September 1979 to October 1981 Eul Ji General Hospital were clinically analized. Among the fifteen cases, fourteen were recovered without sequalae and one was expired ten days after trauma.

Hepatoblastoma (HB) is a rare embryonic malignant tumor of the liver. Most morphological studies on HB have limited to the histological characteristics and only 3 cases of HB have been described in the cytology literature. We present 2 cases of HB occurring in children aged 1 year and 3 years, respectively. The distinctive cytologic features of fine needle aspiration of HB were clusters of tumor cells showing acinar and trabecular pattern, smaller tumor cells with a high nuclear-cytopalsmic ratio and hyperchromatic nuclei having prominent nucleoli, and the presence of extramedullary hematopoiesis and osteoid material. These features were also found in the cell block and the biopsy specimen, and appeared very useful in the differentiation of HB from hepatocellular carcinoma.

Rat thalamocortical slices maintain synoptic connections between thalamus and cortex. When perfused with low Mg++-ACSF, thalamocortical slices exhibited two main types of spontaneous bursting activity. One is monotonic burst of 3-15 Hz and another is multiphasic bursts which have a tonic burst firing period and a late phase of clonic burst firing. These bursts are similar in frequency and during to EEG recordings from human generalized seizures. Exploiting the advantages of in vitro preparations, the electrophysiological action of taurine were studied. Exogeneous application of taurine profoundly decreased spontaneous bursting activities, which it caused only slight reduction of electrically evoked response in cortical layer. Taurine-induced current was blocked by 40 uM bicuculline, GABA receptor antagonist, in acutely isolated coritcal neurons. These results suggest that endogeneous taurine may regulate the hyperexcitablility through GABAa receptor.

Cutaneous or subcutaneous metastases occur in 2% to 9% of visceral malignancies. Skin metastases are seen most commonly from carcinomas of the breast, lung, large intestine. Skin metastases of prostatic origin are quite uncommon and preferentially localized to the lower abdomen and genital area. Two cases of cutaneous metastases of prostatic origin have been reported in the Korean dermatological literature in our review. We report a case of cutaneous metastases from prostatic cancer

Nevus lipomatosus superficialis is a fairly uncommon disease characterized by ectopic fat tissue in the dermis. Lesions most commonly occur on the lower trunk, especially on the back, buttocks or abdomen. Rarely, lesions also occur on the knee, axilla, arm, ear and scalp. To our knowledge this is the first case of nevus lipomatosus superficialis developing on the dorsal foot.

Pemphigus erythematosus (PE) is a superficial type of pemphigus, which can be aggravated by sunlight (espicially UV light). Because of the known side effects of corticosteroids, we evaluated the efficacy of hydroxychloroquine as a corticosteroid-sparing agent and/or the effect of a single-drug regimen in two patients with PE with photosensitivity. We obtained a good therapeutic response with hydroxychloroquine in these two patients with PE. This drug could be used in selected patients with pemphigus who are prednisolone/ immunosuppressive-resistant or who have certain degrees of photosensitivity.

In our series with old electrical burn around the the wrist, there are several characteristics: for example, bad scarring in palm and volar aspect of wrist and distal forearm, large multiple defects of the flexor tendons, low median and ulnar nerve palsy, and occasionally insufficient blood supply. Between 1992 and 1995, we treated 8 cases of 7 patients with staged reconstruction. 4 patients with bilateral involvements had below-elbow amputee of contralateral upper extremity. The common approachs in each were soft tissue coverage, staged tendon reconstructiuon, and opponensplasty. The length of time between the injury and tendon reconstruction was 9 months on an average. Soft tissue coverage consisted of: 1. free tissue transfer (n=3), 2. abdominal (n=3) or groin (n=2). Total numbers of flexor tendon reconstruction were 26. Among them, staged reconstruction using silicone prosthesis were done in 18 tendons and primary tendon graft following tenolysis were done in 8 tendons. The time between first and second stage tendon reconstruction was 4.13 months. In all cases, opponen-splasty using extensor indicis proprius (n=4), extensor pollicis longus (n=2), and extensor digiti mini- mi (n=l), were performed. Good functional improvement of the hand were obtained in all cases. Patient s satisfaction were much better than the degree of functional improvement of the hand.
