A 22-year-old-male patient has numerous brownish-black, soft follicular papules which compatible with acne are scattered on the chest, scapular regions, back and buttocks for 4 5 years duration. Biopsy specimen revealed cystic structures in the mid-dermis lined by squamous cell epithelium w4ich contained laminated keratinous material and varying number of vellus hairs, histopathologically, compatible with diagnosis of eruptive vellus hair cysts. Related literatures and histogenesis were discussed,

Pityriasis rotunda is characterized by perfectly circular to oval brownish scaly patch on the trunk and extremities. This disease is considered to be a form of acquired ichtkyosis of unknown etiology and develops usually in association with certain systemic diseases, such as tuberculosis, malignant neoplasrn, leprosy, ovarian cyst and uterine myoma etc, We experienced 2 cases of pityriasis rotunda on the abdomen, chest and back associated with liver cirrhosis in 66 year old man 43 year old woman and clinical presentation was made with review of related literatures.

PURPOSE: To evaluate abnormal neurosonographic (NSG) findings of thalami and basal ganglia in full term babies with hypoxic-ischemic encephalopathy and to correlate the findings with follow-up studies and prognosis. METHODS: We evaluated 13 full term babies with abnormal NSG findings of thalarni and basal ganglia. NSG was performed within 7 days after clinical abnormalities. Follow-up NSG was done in 11 cases; CT scan in 4 and MRI in 7. We classified NSG findings as diffuse, unilateral, and focal types according to increased echogenicity and evaluated prognosis based on follow-up studies and neurological sequelae. RESULTS: Nine cases of diffuse type had diffuse echogenic changes of bilateral thalami and basal ganglia, slit-like lateral ventricles suggesting cerebral edema, and increased parenchymal echogenicity. In diffuse type, follow-up studies showed more prominent echogencities and ventricular dilatations and cerebromalacia. One case of unilateral type caused by thromboembolism had unilateral echogenicity of right thalamus and basal ganglia with increased echogenicity of the ipsilateral cerebral hemisphere and compression of the lateral ventricle, suggesting cerebral infarction. Follow-up study showed unilateral cystic cerebromalacia. Three cases of focal type had a localized echogenic area in thalamus with lacunar infarction, which decreased in size during follow-up. Among nine cases of diffuse type, one died within 2 days, two were discharged against medical advice, and six had severe neurologic sequelae. One case of unilateral type had a moderate degree of neurologic sequelae. All 3 cases of focal type had normal development. CONCLUSION: Pattems of abnormal echogenicity in thalami and basal ganglia in fullterm infants with hypoxic-ischemic encephalopathy are correlated with the outcome and may be helpful for treatment planning.

Monilethrix is a rare familiar disorder of unknown cause, occurring in either sex, and ueually confined to the scalp. In most cases it is manifested in early childhood. lt is characterized by localized or widespread dystrophy of hair and follicles, the shafts showing regular variations in diameter producing alternate "nodes" and "internodes" which confer a striking beaded or moniliform appearance on the hair. We experienced a case of monilethrix, which was associated with keratosis pilaris and occurred in three generations. The patient's one sibling, mother, 4 uncles and 2 aunts of mother side and grandmother with her sister were all affected with a similar diaorder of hair.

BACKGROUND: Ketamine use in emergency room has been increased. It has rapid onset of action and appropriate duration of action. It does not need endotracheal intubation and produces potent analgesia, sedation, and amnesia. The object of this study is to determine the safety and the degree of physician's satisfaction in relation to ketamine use. MATERIALS AND METHODS: This is a prospective study using protocol. Pediatric trauma patients who need sedation were given IM ketamine(4mg/kg) and atropine(0.01mg/kg) in a same syringe. Monitoring of patients was done by EM residents and complications of ketamine use were recorded. Physician's satisfaction was also recorded after the procedure. RESULTS: Intramuscular ketamine was administered 54 times, mainly for laceration repair. Physicians completed protocol for 51 of treated children. The median time for onset of sedation was 6.5+/-2.4 min, and duration of action was 32.4+/-10.8 min. Hypersalivation occurred in 9.8%(n=5); random movement 3.9%(n=2), emesis during procedure(n=1), emesis at home(n=1), and transient oxygen desaturation(n=1). All were quickly identified and treated without specific airway management and sequelae. Of 84% of physicians was satisfied with ketamine use for pediatric sedation. CONCLUSION: Intramuscular ketamine can be administered safely and satisfactorily in emergency room to facilitate pediatric procedures in conjunction with a defined protocol and appropriate monitoring.

A case of metastatic tumor of the skin is described with literature review. Cutaneous metastases of malignant tumor is rarely seen but lung cancer in male and breast cancer in female are not infrequently reported. This patient, 37 year old male, had lung cancer, had several chest tappings for pleural effusion and a pleural biopsy. 8 months later, skin manifestation of diffuse erythematous sclerotic patches and confluent nodules was noted on pleural biopsy site, right lateral chest wall. Histopathological finding was compatible with metastatic carcinoma. This metastatic skin tumor is considered to be arisen from the lung probably due to pleural biopsy.

This study was designed to evaluate the potential applicability of magnetic resonance imaging (MRI) for the diagnosis of acute renal vein thrombosis. Renal vein thrombosis was experimentally induced by surgical ligation of the left renal vein in a total of 21 rabbits. MRI was performed with a 0.5 Tesla superconductive magnetic system. Spin echo technique was used with varying TR and TE parameters. Spin echo images of the rabbit kidney were analysed for morphology and signal intensity. T1 and T2 relaxation times of the renal cortex and medulla were calculated from the images. After venous ligation, kidneys became enlarged. Low signal band along the outer medulla in T2 weighted images were characteristically shown from 1 hour to 3 days after ligation, Changes of cortex to medullar contrast (CMC) values were significant (p<0.05) in T1 - and T2- weighted images of the ligated side. T1 and T2 relaxation times were significantly prolonged (p<0.05) on the ligated side, both in the cortex and medulla from 1 hour to 2 weeks after the ligation, while T2 relaxation time on the contralateral side was significantly prolonged both in the cortex and medulla 2 weeks after venous ligation. The most useful MRI criteria for the diagnosis of renal vein thrombosis were enlarged renal size, and the low signal band along the outer medulla of ligated kidney. The relative intensity difference between cortex and medulla (CMC) in T1-and T2-weighted images, and T1 and T2 relaxation times were suggested to be the useful MR parameters for the diagnosis of acute renal vein thrombosis.
