OBJECT: This study was performed in order to examine the correlation between acute neuroleptic-induced dystonic reactions and serum iron level. METHOD: Serum iron levels were measured in psychiatric inpatients who had developed acute neuroleptic-induced dystonia(N=41) and in control patients with no history of acute dystonic reactions(N=37). Serum iron levels were compared in acute dystonic inpatients before starting treatment with neuroleptics and after acute dystonic reaction. RESULTS: The patients exhibiting acute dystonic reactions had significantly lower serum iron levels than the patients without acute dystonic reactions. CONCLUSION: This result supports an association between low serum iron and the occurrence of neuroleptic-induced acute dystonic reactions.

OBJECTIVE: It has been thought that estrogen has neuroleptic like effect in women schizophrenic patients. This study aimed to investigate neuroleptic side-effects severity in women with schizohrenia and to investigate their putative association with variations in sex steroids over menstrual cycle. Based on the estrogen theory, The author hypothesized that parkinsonian side-effects would be exacerbated when estrogen levels were high. METHOD: 26 schizophrenic women were assessed using the ESRS(Extrapyramidal Symptom Rating Scale) and estrogen analysis. Tests were conducted twice, in the mid luteal and mid follicular phase. RESULT: It was hypothesized that high level of estrogen would lead to an exacerbation of parkisonian side-effects but the results indicated that parkinsonian side effects decreased overall when estrogen levels were high. This effects were more marked for the group taking typical neuroleptics than those taking atypical neuroleptics. CONCLUSION: The results of this study suggest that estrogen and progesteron may reduce the severity of neuroleptic indeced extrapyramidal side effects over menstrual cycle in women with schizophrenia. It was concluded that estrogen has different effects on dopamine dynamics in the mesolimbic and mesostriatal pathways according to estrogen, progesteron, catecol estrogen, prolactine.

Wiskott-Aldrich syndrome is an X-linked combined immunodeficiency disorder characterized by severely decreased number of platelets which are small in size, eczema resembling atopic dermatitis and recurrent infection. The serum of the patient contains elevated concentrations of IgA and IgE, whereas the IgG level is usually normal and IgM level is decreased. The patients also shows skin test anergy and progressive T-lymphocytopenia. Bleedings and recurrent infections are the main causes of death and the patients usually die before age 10. Bone marrow transplantation is accepted to be the only radical therapy. We experienced a case compatible with Wiskott-Aldrich syndrome in a 5 year old male child who accompanied above clinical manifestations and laboratory findings.

The use of CT is most reliable in diagnosis and management of brain abscess. Authors analized 17 cases of pathologically and clinically proven brain abscess during the period of 39 months from Jan. 1978 to Mar, 1982 at National Medical Center. The results were as follows; 1. The sex ration 9 males to 8 females, and no sexdifference was seen, and the greatest number of cases were seen below the age of 30(65%). 2. The otogenicinfection was the most frequent predisposing factors(8 cases). Other predisposing factors were postoperative infection (2 cases), pulmonary infection (2 cases), and congenital heart disease(2 cases). The most common site ofinvolvement was posterior fossa(5 cases). Next was temporal lobe (4 cases), and temporoparietal lobe (3 cases). 3.Most common presenting symptoms were headache, fever, focal neurological signs, and dizziness. 4. Among the 22 brain abscesses of 17 patients, the msot frequent CT finding in precontrast scan was a low density surrounded by afaint dense or dense ring (11 cases). Next was purely low density (6 cases). Associated hydrocephalus was found in4 cases, and multiple or multiloculated abscess was seen in 4 cases. 5. In post contrast scan, brain abscessusually show complete, oval or round shaped, thin, evening righ enhancement with mild or moderate surroundingedema, but there was no specific enhancement.

This paper describes a case of agenesis of the right lung in a male neonate, who suffered respiratory difficulty. He was evaluated by plain X-ray, bronchography, lung perfusion scan, chest CT, and brain CT. After he died, autopsy was performed. The results revealed multiple anomalies which included cleft lip and palate, absence of left thumb and radius bone, hemivertebra between L1 and L2, arachnoid cyst in occipital lobe of brain. We report this case with brief review fo some related literature.

We retrospectively analyzed the Magnetic Resonance (MR) imaging findings in 41 cases of histologically proved malignant tumors of oral cariey. The diagnostic value of MR imaging in detection and delineation of the lesions was assessed. The value of MRI was compared with that of Computed Tomography (CT) in 14 patients. Thirty-four cases of 41 malignant tumors were squamous cell carcinomas. Adenoic cystic carcinomas (2 cases), malignant melanomas (2 cases), non-Hodgkin lymphomas (2 cases) and mucoepidermoid carcinoma(1 cases) were also included in this study. Most of the lesions were isointense or slightly hyperintense to muscle on T1 weighted images and showed variable degrees of high signal intensity on T2 weighted images. Two cases of malignant melanomas showed characteristic hyperintensity on T1 weighted images. T2 weighted image was better in detection and delineation of tumor in most of the cases. In 6 cases, Gd-DTPA-enhanced T1 weighted image was better than T2 weighted image. T2 weighted image was useful for the evaluation of deep tissue infiltration and T1 weighted image was useful for the evaluation of bone invasion and superficial tissue plane invasion. The lesion was detected only by MR in 3 cases of 14 in which CT was also performed. MR imaging was more sensitive in the evalustion of bone marrow involvement. MR imaging is very useful modality in evaluating oral cavity malignany and is superior to CT in delineation of the as well as in the evaluation of mandible invasion.

Most authorities including WHO recommended immununizing infants with BCG as early as possible in areas prevalent with tuberculosis, however the optimal time for immunization has not well been characterized. Therefore the investigation was undertaken by vaccinating various infant groups of different ages with BCG and subsequently evaluating for adverse effects and tuberculin reactions, in order to contribute to undestanding the optimal time for immunization. Four hundred eighty three infants from the newborn nursery and the well baby clinic of Hanyang University Hospital who had no family history of tuberculosis were divided into three groups; group I of infants immunized within 7 days after birth, group II of infants immunized at about 1 month of age and group III of infants immunized at about 3 months of age. To each infant 0.1 ml of BCG(Institute Merieux, France) was administered intradermaly and approximately 3 months later tuberculin skin test using 5 TU PPD (NIH, Korea) was performed. Adverse reactions following BCG vaccination such as temperature elevation, induration alone or with suppuration at or near the injection site, and lymph node enlargement were also analyzed. The summary of the results is as follows. 1) Distribution of diameters of induration on tuberculin skin test illustrated incomplete bimodal configuration in all three different age groups. The means 2 standard deviations of diameters of indurations distributed on the main bells were 10.07 4.52 mm in group I, 10.65 3.82 mm in group II, and 10.83 5.08 mm in group III, and were not significantly different. 2) Criteria for positive tuberculin reaction was diameters of indurations equal to or greater than 6mm, 2 standard deviations below the mean values of diameters of indurations on the main bells. 3) The positive tuberculin reaction rates of 85.8% in group II and 88.6% in group III were significantly greater than 74.1% in group I. 4) Incidence of complications following BCG vaccination including temperature elevation, induration with suppuration, and localized lymphadenopathy was not different among three groups and the serious complications such as temperature elevation and lymphadenopathy were minimal. The data indicate that it is appropriate to immunize infants with BCG at about one month of age and the incidence of complications following BCG vaccination was not different among three infant groups of different ages.
