OBJECTIVES: MR fluid-attenuated inversion recovery(FLAIR) image uses paired long inversion time and relaxation time that nulls the signal from CSF. With nulling of the CSF long echo time readout could be used to increase T2-weighting, hence improving the conspicuousness of most tissue lesions without the deleterious effects of CSF artifact seen on T2 weighted sequence. We examed the usefulness of FALIR image in the diagnosis of mild head injury. METHODS: A total of 38 patients with mild head injury were examined by FLAIR image. We compared those images with CT scan and T1, T2-weighted images. Careful observation of MR images were done by two well-trained neuroradiologists. Each image was compared for conspicuousness and detectability of traumatic lesions might have shown abnormal signal intensities. The Wilcoxon signed ranks test was used for statistical evaluation. RESULTS: The FLAIR image was significantly more sensitive than those of other images(p<0.001). T2 FFE(Fast Field Echo) image was more useful for detection of small petechial hemorrhages. CONCLUSION: FLAIR image is considered to be more sensitive than those of conventional MR images in the evaluation of mild head injuries.

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.

In Asian double eyelid surgery, there have been two approaches to form a suprapalpebral fold: the buried suture (nonincision) method and the full external incision method. Usually excessive fat tissue in upper eyelid has been removed by using a full external incision method, or 2 to 3 partial incisions with buried suture method. The full external incision method is more invasive than the buried suture method, which is not suitable for patients with excessive orbital fat. From March 1999 to January 2002, we have introduced the single 5 mm-partial incision method to 216 patients. This method is applied to patients who have excessive amount of orbital fat or those who do not have excessive orbital fat but which must be removed for better result. These patients have bulging supra-crease areas when we form suprapalpebral folds with a curved wire loop preoperatively. Excessive orbital fat was removed through a single 5 mm incision in the middle of designed eyelid crease and tarso-dermal suture was performed. At another 2 to 3 points, through skin stab punctures by using 18 gauge needle, full-thickness eyelid tarso-dermal sutures were done. Pretarsal and preseptal orbicularis muscles were preserved. If muscles were removed, that could result in thinning of the overlying skin and could make suprapalpebral fold unnatural. This method has several advantages. First, we could perform the operations safely in patients who have excessive fat tissue, without a full external incision. Second,fat tissue can be removed almost totally by a single 5 mm-partial incision. Third, we can minimize the scar formation, and the possibility of complications, and make healing process and operation time shorter compared to the full incision technique. However a very delicate technique is required in this method. In patients who have a thick orbital septum, a superiorly located fat pad, and a bleeding tendency, exposure of fat tissue could be difficult and injury of levator muscle aponeurosis is possible. The complications of this method are the possibility of disappearing of the crease with the lapse of time(3 percents), and suture granuloma formation(less than 1 percent). In conclusion, patients who have excessive fat tissue in upper eyelid don't have to proceed a full incision, and can have more excellent results with this single 5 mm-partial incision method.

Behcet's disease (BD) is a multisystem inflammatory disorder dominated clinically by recurrent oral and genital ulceration, uveitis and erythema nodosum. BD is very rare in children, especially those less than 10 years of age, who account for only an estimated 5% of all cases. Gastrointestinal ulcers, in patients with Behcet's disease with intestinal involvement are rare and have been reported in only 1-2% of all cases. The intestinal ulcers of Behcet's disease are usually multiple and scattered and tend to cause perforations associated with significant morbidity. Patients with BD and abdominal symptoms must be evaluated thoroughly for potential perforation of the gastrointestinal tract. Here we report the case of a 4 year 9 month old child with multiple perforations of the gastrointestinal tract associated with BD.

Initial rapid diagnosis of primary pulmonary cryptococcosis(PPC) occurring in a immunocompetent host was made by transthoracic fine needle aspiration cytology of a solitary subpleural nodule. Numerous refractile spherical organisms surrounded by a clear halo were demonstrated with haematoxylin-eosin and Papanicolaou stains. The organisms, 5 15 micrometer in diameter, were easily demonstrated with Gomori methenamine-silver stain. Many of the organisms showed narrow-base budding. Carminophilic cell walls were well demonstrated with mucicarmine stain.

BACKGROUND: This study compared the incidence of emergence agitation and the recovery profile from sevoflurane anesthesia after thiopental sodium, propofol or ketamine induction in pediatric inguinal herniorrhaphy. METHODS: Forty eight children aged 1-7 years undergoing high ligation due to an inguinal hernia were examined. All patients received a 0.004 mg/kg glycopyrrolate injection for premedication prior to induction and were randomly assigned to receive thiopental sodium 5 mg/kg (Group T, n = 16), propofol 2 mg/kg (Group P, n = 16) or ketamine 1 mg/kg (Group K, n = 16) for induction. The side effects during the induction time were checked. All patients received sevoflurane (2-2.5 vol%)-N2O (2 L/min)-O2 (2 L/min) for the maintenance of anesthesia. Ventilation was given to assist spontaneous ventilation using a facial mask. The agitation score, pain score, discharge score, incidence of emergence agitation and postoperative side effects in the three groups were assessed at the recovery room and compared. RESULTS: The emergence time in Group T (7.5 +/- 1.8 min) was significantly rapid. The agitation and pain scores were significantly low in Group P. The discharge score was more rapid in Groups P and K than in Group T. The incidence of emergence agitation was similar in all three groups. CONCLUSIONS: Although recovery was faster and emergence agitation was low in the propofol group, propofol induction was not smooth compared with thiopental or ketamine induction. The incidence of emergence agitation after sevoflurane anesthesia in pediatric inguinal herniorrhaphy was similar in the thiopental sodium, propofol or ketamine induction groups.

A 12-years-old female admitted to the hospital with the complaint of pain on the right upper chest area which persisted about 1 month prior to admission. Cafe-au-lait spots of various size laying on a whole body and freckling on the axilla were found on physical examination. A huge mass was found on the plain chest X-ray and on chest MRI. The mass encroached thoracic spine, posterior rib, back muscles, and then into the neural canal and compressed thoracic spinal cord. On the 5th day of hospitalization, the patient complained tingling on the both legs and 2 days later, monoparesis on the right leg. Open thoracotomy and decompressive laminectomy was done to remove mass. Pathologic reports confirmed rhabdomyosarcoma, embryonal type.

BACKGROUND: Mitral valve repair has been suggested to provide better postoperative outcome than valve replacement for mitral regurgita tion. MATERIAL AND METHOD: From Janu ary 1996 to May 2000, 87 patients had mitral valve repair(59 patients) or replac ement(28 patients) for mitral regurgitation. RESULT: The two groups were si milar in age, sex, and functional class. The cause of mitral regurgitation in th e repair group was degenerative in 45 patients, rheumatic in 12 patients, endoca rditis in 1, and ischemic in 1, and in the replacement group was degenerative in 12 patients, rheumatic in 11 patients, endocarditis in 4 and traumatic in 1 pat ient. A Carpentier ring was used in 51 patients and the most common size was 30 mm. The aortic cross-clamp time was 88.3+/-24.7 minutes in the repair group and 7 0.3+/-23.8 minutes in the replacement group(p<0.05), and total pump time was 13 9.6+/-30.5 minutes and 110.4+/-34.3 minutes(p<0.05) respectively. There was no hos pital death in both groups. Four-year actuarial survival was 97.9% for the repai r group and 100% for the replacement group(p = not significant). Postoperative c ardiothoracic ratio and ejection fraction decreased, and postoperative functiona l class improved in both groups(p = not significant). CONCLUSION: Mitral valve repai r for patients with mitral regurgitation can be performed with the satisfactory results as valve replacement.

BACKGROUND: Basal cell carcinoma(BCC) does not commonly occur in dark-skinned people, although it is the most common cancer of light-skinned people. So it has been known that incidence of BCC is lower than that of squamous cell carcinoma(SCC) in Asian and Africans. However, several recent Korean articles have reported the reversal of the ratio of SCC to BCC. There has been no report about BCC following a nationwide survey in Korea. OBJECTIVE: Our purpose was to confirm the trends in BCC and SCC, and to identify the clinical and histopathological characteristics of BCC. METHODS: A clinical and histopathological analysis was done retrospectively with patients diagnosed as BCC from the Department of Dermatology of 15 University Hospitals or General Hospitals during the last 20 years(1977-1996). Annual incidence of BCC was compared with that of SCC at the same situation. We compared the results with those in other races statistically. RESULTS: 1. Incidence of BCC was 0.16% compared with 0.11% of SCC. The increasing incidence of BCC was more pronounced than that of SCC, although they were increased gradually. 2. The male-female ratio was 1:1.07, and the most frequent age group was the 6th decade(30.1%). 95% of the patients were older than the age of 40 years with the mean age of 62.7 years. 3. The most commonly involved site was the face(84.9%), especially on the nose, cheek, and eyelids. 4. The most frequent histologic pattern was nodulocystic type(35.4%), followed by mixed(30.1%), infiltrative(9.3%), superficial(6.7%), micronodular(6.2%), adenoid(5.9%), metatypical(4.0%), morpheaform(2.1%), and fibroepithelioma type(0.3%). 5. Histologically, 45.3% of BCC contained pigment. The histologic pattern most frequently associated with pigmented BCC was mixed type(53.1%) followed by nodulocystic(51.2%), superficial(46.8%), micronodular(38.6%), and adenoid type(33.3%). 6. Overall recurrence rate was 6.3%. Morpheaform, infiltrative, and metatypical BCC have a high erincidence of recurrence(26.3%, 13.2%, 8.1%, respectively). Therapeutic modalities that showed high recurrence rate was 5-FU, curettage and electrodessication, and cryotherapy(33.3%, 28.6%, 16.8%, respectively). CONCLUSION: It was confirmed following a nationwide survey that increasing incidence of BCC was more pronounced than that of SCC since early 1980s and BCC was the most common skin cancer in Korea.
