We retrospectively evaluated datas on 61 cases of neonatal sepsis confirmed by clinical symptoms and blood cultures at the NICU of Gil general hospital From Mar. 1989, to Fed. 1992. The results obtained were as follows: 1) The mean gestational age was 32.7+/-2.6 Weeks in preterm infants, and 39+/-1.5 weels on term infants. The mean birth weight was 1,701.4+/-422.4 g in preterm infants, and 3,232+/-581.7 g in term infants. 2) There were 61 infants with neonatal sepsis identified among 13, 486 live births, resulting in an incidence of 0.45%. The sex ratio of male to female was 1.2:1. The incidencdence was higher in preterm infants (2.21%) than in term infants (0.27%). 3) The most commom presenting symptoms of neonatal sepsis were apnea and bradycardia (53.6%) in preterm infants, jaundice (33.3%) in term infants 4) The concurrent diseases in neonatal sepsis were urinary tract infection (UT)(25%), pneumonia (21%), hyaline membrane disease (21%) in the order of frequency. Hyaline membrane disease (33.3%) was the most frequently associated disease in preterm infants, UTI (41.4%) in term infants 5) Gram positive organisms were isolated in 33 casess (52%), gram negative organisms in 30 cases (48%). The most common ortanism isolated from blood cultures was CONS (28.6%). The more common organisms in preterm infants were CONS (26.7%), Enterococcus (23.3%) and Klebsiella (10%). CONS (30.3%), E. Coli (27.3%) and Staphylococcus aureus (12%) were more frequent in term infants. 6) The significant diagnostic laboratory findings for neonatal sepsis were leukopenia ( < or =5000), I:T 0.16, thrombocytopenia ( <150,000/mm3), CRP> or =1+.2 or more of abnormal hematologic values were significantly more frequent in preterm infants (P< 0.05). 7) The risk factors associated with neonatal sepsis were endotracheal intubation (57%), birth ashyxia (Apgar score< or =6 at 5 min.)(39%) and umbilical catheterization (35.7%) in preterm infants, while endotrachial intubation (12.1%), birth ashyxia (12.1%) and premature rupture of membrane ( > or =24hrs)(9.0%) in term infants. 8) Early onset neonatal sepsis (72< or =hr of age) was found in 40 cases (65.6%). 9) The overall mortality rate of neonatal sepsis was 26.0%(39,3% in preterm infants, 15.2% in term infants). The mortality rate was significantly high in pseudomonas infection. 10) In low birth weight infants, the susceptibility to neonatal sepsis was greatest in the infants of lowest birth weight (1,00-1,500 gm) and the mortality rate was inversely proportional to birth weight. 11) Sensitivity to antibiotics in gram postitive organisms were chlorampjenicol (37%), Erythromycin (29%), ampicillin (26%) and cephalothin (26%). It clearly showed that newer antibiotics such as vancomycin is neccessary. In cases of gram negative organisms, sensitivity to antibiotics were amikacin (85%), gentamicin (65%), tobramycin (58%) and cephalothin (54%).

Newborn premature babies have lwo levels of transplacentally acquired maternal immunoglobulin which is mostly transferred after 32~34 weeks gestaton, therefore they may have IgG deficiencies that increase their susceptibility to bacterial infection. We performed this study to determine whether intravenous immunoglobulin (IVIG) therapy improves mortality or infection occurrance rate. From 1 october 1991 to 31 July 1992, 73premature newborn infants with gestational age< or =34weeks were enrolled: the theatment group, consisting of 43infants who received prophylactic intravenous immunoglobulin therapy (500mg/kg/week) and the control group, consisting of 30infants who did not receive. prophylactic intravenous administration of immunoglobulin to preterm infants with a gestational ageage< or =34week, at a dose of 500mg/kg/week, results in maintenance of a satisfactory serum IgG level throughout the high-risk period for infection. But the incidence rates of proven or very probable sepsis, mortality for sepsis and total mortality in the infants receiving intravenous immunoglobulin were not significant differences when compared with those in the control infants. No adverse effects were noted after immunoglobulin transfusions in our subjects. In conclusion, our study does not show any decrease in bacterial infection rate or in mortality rate, and no study in the literature has shown absolute proof of the prophylactic efficacy of IVIG in premature newborns. Larger studies are necessary to confirm these observations and to determine more effective dosing schedules and the optimal levels of orhanism-spectific antibodies. And specific hyperimmnue of monoclonal antibody preparations may be required to provide reliable sources of effective prophylactic to premature neonate with high risk in bacterial sepsis.

Holoprosencephaly is a rare malformation complex or development defect including different degrees of incomplete cleavages of the embryonic prosencephalon and varying degrees of the midface defects, resulting from the defect of prechordal mesoderm, migrating forward into the area anterior to the notochord during the third week of fetal development. Early antenatal diagnosis of holoprosencephaly is important to find out its severity, to predict its prognosis, and to determine proper management according to its prognosis and severity. The possibility of early antenatal diagnosis of holoprosencephaly by ultrasound has been suggested, but occasionally missed and rarely confirmed. We present one case of lobar holoprosencephaly, diagnosed postnatally and one case of alobar holoprosencephaly, diagnosed antenatally in our hospitals.

Hashimotos thyroiditis and Graves disease have been thought to be the autoirnmune diseases having their distinct and separate clinical and pathologic features. Because of the partial and complete simi1arity in histologic feature, it has been hypothesized that Hashimoto's thyroiditis and Oraves disease may be interrelated. Several patients who had been diagnosed as Graves disease showed features of hypothyroidism, and were proven to have histologie features of Hashimotos thyroiditis in their thyroid tissue. Two meehanisms had been suggested to explain tbis phenomenon. One is that the combined Hashimotos thyroiditis in Graves' disease may become predominant with time, The other is that the amount of TSH receptor blocking antibody may increase in the course of Graves disease. Early recognition of these patients would be impartant to estabilish therapeutic plan. Futhermcee, extensive study of these patients would give more understanding of the mechanism of these diseases. Here we report 5 cases of clinically diagnosed Graves disease with pathologic features of Hashimotos thyroiditis or focal lymphocytic thyroiditis.

OBJECTIVE: To investigate neural correlates associated with recovery of motor function over 6 months in patients with basal ganglia (BG) stroke using acetazolamide (ACZ) stress brain-perfusion single-photon emission computed tomography (SPECT). METHODS: Medical records of 22 patients presenting first-ever BG stroke were retrospectively reviewed. Regional cerebral blood flow (CBF) and cerebrovascular reserve (CVR) were measured for 9 regions in each cerebral hemisphere (primary motor cortex, supplementary motor area, premotor cortex, prefrontal cortex, temporal lobe, parietal lobe, occipital lobe, BG, and thalamus). The Fugl-Meyer Assessment (FMA) motor score was used to assess motor function. RESULTS: After ACZ injection, CBF of all regions of interest (ROIs) increased compared with baseline. Baseline CBF of all ROIs was not significantly correlated with changes in FMA upper or lower motor score. However, multivariate analysis revealed CVR was significantly associated with change in FMA upper score in the ipsilateral primary motor cortex (R2=0.216, p=0.017), the ipsilateral parietal lobe (R2=0.135, p=0.029), and the contralateral primary motor cortex (R2=0.210, p=0.041). CONCLUSION: CVR in the bilateral primary motor cortex and ipsilateral parietal lobe was associated with restoration of upper motor function 6 months after BG stroke. SPECT is a readily available imaging modality useful in studying brain residual function in patients with BG stroke.

Moxibustion is a traditional Oriental medicine therapy that treats the symptoms of a disease with thermal stimulation. However, it is difficult to control the strength of the thermal or chemical stimulus generated by the various types and amounts of moxa and to prevent energy loss through the skin. To overcome these problems, we previously developed a method to efficiently provide RF thermal stimulation to subcutaneous tissue. In this paper, we propose a finite element model (FEM) to predict temperature distributions in subcutaneous tissue after radio-frequency thermal stimulation. To evaluate the performance of the developed FEM, temperature distributions were obtained from the FEM, and in vivo experiments were conducted using the RF stimulation system at subcutaneous tissue depths of 5 and 10 mm in the femoral region of a rabbit model. High correlation coefficients between simulated and actual temperature distributions—0.98 at 5 mm and 0.99 at 10 mm—were obtained, despite some slight errors in the temperature distribution at each depth. These results demonstrate that the FEM described here can be used to determine thermal stimulation profiles produced by RF stimulation of subcutaneous tissue.

This year, the Korean Society of Nuclear Medicine (KSNM) is celebrating its 60th anniversary. Treatment, as well as diagnosis, has played a very important role in the development of nuclear medicine. Since I-131 was used for thyroid therapy in 1959, other radionuclide therapy is still being used, and attempts to use new radionuclide are increasing. In this review, we briefly summarize and introduce the therapies such as radioimmunotherapy, transarterial radioembolization, radionuclide therapy for neuroendocrine tumors, peptide receptor radionuclide therapy, control of metastatic bone pain, radiation synovectomy, radionuclide brachytherapy, alpha particle therapy, and boron neutron capture therapy, which has been being attempted so far in the field of nuclear medicine.

A 77-year-old male underwent open repair for a right indirect inguinal hernia and complained of right scrotal pain on the third postoperative day. Color Doppler imaging revealed decreased blood flow with heterogeneous hypoechogenicity in the right testis. A Tc-99m pertechnetate testicular scan showed diffuse hyperemia and increased uptake in the right scrotum. Additional SPECT/CT revealed a photon defect in the right testicle with increased uptake in the peri-testicular area. A subsequent operation revealed a large hematoma in the right spermatic cord and consequent right testicular infarction, and right orchiectomy was performed.
