We have experienced a case of infantile nephritic syndrome confirmed by renal biopsy in a 13-month-old female patient who showed and develop mental retardation and persistent proteinuria. She revealed mild eyelid edema, joint laxity, delayed speech development and adrenal cortical calcification on the radiologic study. Renal biopsy showed microcystic tubular change, micro-glomeruli and marked mesangial proliferation.

The recent availability of recombinant human erythropoietin has opened new perspectives in the management of a variety of anemias. Clinical trials have been initiated in several countries using different approaches and methodology. We randomly assigned twelve premature infants(gestational age < 32 week) at high risk of requiring erythrocyte transfusion for anemia of prematurity with either subcutaneous recombinant human erythropoietin or a placebo. Treatment with rHuEPO was initiated at a dose of 100 units/kg day for 3 days a week. All patients were given supplemental oral iron therapy at a dose of 3 mg/kg per day, as tolerated and oral vitamin E at a dose of 25 units per day. Treated and control babies did not differ with respect to weight, hematocrit, overall mean reticulocyte count or rate of growth respectively. However, reticulocyte counts increased earlier in patients given rHuEPO. We conclude that rHuEPO administration is safe and feasible at the dose studied.

Acute infarcts of the anterior inferior cerebellar artery (AICA) territory are unusual. Furthermore incomplete AICA infarcts are perplexing because of its variations of vascular anatomy and inconsistent clinical features. We present a case with clinical features of AICA infarction, which consist of ipsilateral peripheral-type facial palsy, vertigo, and contralateral facial and upper limb sensory changes without motor weakness. The patient had hypertension and was a current smoker. The high signal intensity on inferior pontine tegmental area was found on MRI and the R2 interneuronal dysfunction was note on Blink reflex. The angiographic findings didn't show any focal vascular lesions, which is contrary to the pathogenesis of AICA infarction published previously. On the clinical ground, the present case reserves to attention in that patients with peripheral-type facial palsy should be properly evaluated and with thorough neurological examination and we could differentiate between the incomplete AICA infarcts such as Gasperini syndrome and Bell's palsy.

PURPOSE: Leptin is a highly hydrophilic 16-kDa protein which is produced in the adipose tissue and participates in the regulation of food intake and energy expenditure. The aim of the present study was to examine the relation between umbilical cord blood leptin concentration and intrauterine growth. METHODS: Ninety-seven full-term newborn infants who were born in Yeungnam University Hospital from July to August 1998 were included in the study. They were divided into 3 groups related to birth weight : appropriate for gestational age(AGA) group(n=73), large for gestational age(LGA) group(n=17), small for gestational age(SGA) group(n=7). Birth weight, head circumference, mid-arm circumference, mid-arm circumference to head circumference ratio, Ponderal index, and BMI were measured at birth. Maternal body weight and placental weight were measured. Leptin concentrations of cord blood and maternal serum were measured by a RIA method, and testosterone, estradiol, insulin, c-peptide, glucose, white blood cell, hemoglobin, platelet count of cord blood were also measured. RESULTS: Leptin concentration in cord blood was positively correlated to birth weight and body length. Leptin concentrations(microgram/L) in cord blood were significantly different among groups(10.1+/-1.1 in LGA group, 8.7+/-0.9 in AGA group, 1.7+/-0.1 in SGA group). There was a statistically significant difference in leptin concentration of cord blood between female and male infants(11.6+/-1.9, versus 6.7+/-0.9). There was no significant correlations between leptin concentration of cord blood and placental weights or maternal leptin concentration. Therefore leptin concentration of cord blood can not inflect maternal leptin concentration but intrauterine fetal growth. CONCLUSION: Leptin in cord blood might originate mainly from fetal adipose tissue rather than the placenta, and may be related to fetal growth.

A nationwide survey was conducted to investigate the annual occurrence rate of neonatal sepsis, maternal risk factor in neonatal sepsis, localized infection in neonate, causative organism in nosocomial infection and the most common causative organism in neonatal sepsis in Korea. Clinical and bacteriological data were collected from thirty seven neonatal units through retrospective review of the medical records of the newborn infants who were confirmed as neonatal sepsis by isolating organisms from blood culture during one year study period from January to December in 1997. 78,463 neonates were born at 37 hospital in 1997 and 20,869 neonates were admitted to the neonatal units. During this period, 772 episodes of neonatal sepsis were recorded in 517 neonates. The occurrence rate of neonatal sepsis was 0.73%(0~2.95%). Male to female ratio was 1.15:1 and 303 cases(42.1%) were born prematurely. The main pathogens of early onset sepsis were S. aureus(20%), S. epidermidis(14.4%) and coagulase negative Staphylococcus( 14.4%). Gram negative bacilli including Enterobacter spp (7.2%), E.coli(5.1%), Klepsiella(4.5%), Pseudomonas(3.7%) Enterobacter faecium(3.6%) constitute 24.1%. Only two cases of group B beta-hemolytic Streptococcus were isolated. Common obstetric factors were PROM(21.1%), difficulty delivery(18.7%), fetal tachycardia(5.3%), chorioamnionitis(4.9%), maternal fever(4.7%). The main pathogens of late-onset sepsis were S. aureus(22.3%), S. epidermidis(20.4%) and CONS(9.9%). There were 6 cases (1.0%) of Candida sepsis. Frequent focal infections accompanying sepsis were pneumonia(26.1%), urinary tract infection(10.5%), meningitis(8.2%), and arthritis(3.6%). S. epidermidis(22.0%) and S. aureus(21.7%) were also the most common pathogens in 373 nosocomial infection.

Medial gastrocnemius flap has been known as a useful option for soft tissue reconstruction of the knee and upper 1/3 of lower extremity, but it has a limitation to cover the lateral defect of the knee joint. We performed the combined gastrocnemius-medial sural artery perforator flap for coverage of the anterolateral defects of the knee joint, which is compound flap using a medial gastrocnemius flap and a medial sural artery perforator flap. This flap is a useful method for reconstruction of anterolateral knee defects, providing a easy dissection without the microsurgery and intramuscular dissection of the perforators.

PURPOSE: To describe MR findings and differential points of supratentorial cystic intracranial lesions. MATERIALS AND METHODS: We retrospectively reviewed and analyzed the MR findings of 59 patients with supratentorial cystic intracranial lesions, and classified them as follows: tumor-associated cyst, infectious cyst, ex-vacuo type cyst, and congenital/developmental cyst. RESULTS: Among 59 patients, 47 tumor-associated cysts were seen in 17, 42 infectious cysts in 13, 17 ex-vacuo type cysts in 10, and 19 congenital/developmental cysts in 19. In 44 of 47 tumor-associated cysts, increased or inhomogeneous internal signal intensity was seen on T1-weighted image, 37 of 47 showed thick uneven walls ; 35 of 47 had enhancing solid components and there was variable perifocal edema and mass effect. Infectious cysts were multiple (11 of 13). In cases of brain abscess, increased internal signal intensity on T1-weighted image, low signal intensity of abscess wall on T2-weighted image, thick even enhancing wall, and marked perifocal edema(4 of 4) were seen in all four cases. Cysts in cysticercosis were variable in appearance depending on the stage, but were smaller than other cystic lesions. Ex vacuo type cysts were of uniform CSF signal intensity in all pulse sequences and there was no identifiable wall or enhancement associated with enlarged adjacent ventricle and encephalomalacia(17 of 17). Congenital/developmental cysts showed a single lesion(19 of 19), a signal intensity similar to CSF in all pulse sequences(15 of 19), no identifiable wall(16 of 19), no enhancement(17 of 19), and no perifocal edema(19 of 19). CONCLUSION: MR was used to categorize supratentorial cystic intracranial lesions into four groups on the basis of their number, size, internal homogeneity of signal intensity on T1-weighted image, enhancing pattern, perifocal edema and mass effect, thereby improving diagnostic specificity and patient management.

OBJECTIVE: To investigate skeletal and dental changes after application of a mandibular setback surgery-first orthodontic treatment approach in cases of skeletal Class III malocclusion. METHODS: A retrospective study of 34 patients (23 men, 11 women; mean age, 26.2 +/- 6.6 years) with skeletal Class III deformities, who underwent surgery-first orthodontic treatment, was conducted. Skeletal landmarks in the maxilla and mandible at three time points, pre-treatment (T0), immediate-postoperative (T1), and post-treatment (T2), were analyzed using cone-beam computed tomography (CBCT)-generated half-cephalograms. RESULTS: The significant T0 to T1 mandibular changes occurred -9.24 +/- 3.97 mm horizontally. From T1 to T2, the mandible tended to move forward 1.22 +/- 2.02 mm, while the condylar position (Cd to Po-perpendicular plane) shifted backward, and the coronoid process (Cp to FH plane) moved vertically. Between T1 and T2, the vertical dimension changed significantly (p < 0.05). Changes in the vertical dimension were significantly correlated to T1 to T2 changes in the Cd to Po-perpendicular plane (r = -0.671, p = 0.034), and in the Cp to FH plane (r = 0.733, p = 0.016), as well as to T0 to T1 changes in the Cp to Po-perpendicular plane (r = 0.758, p = 0.011). CONCLUSIONS: Greater alterations in the vertical dimension caused larger post-treatment (T2) stage skeletal changes. Studying the mandibular position in relation to the post-surgical vertical dimension emphasized the integral importance of vertical dimension control and proximal segment management to the success of surgery-first orthodontic treatment.

Regarding the removal of a gastric bezoar, laparoscopic surgery was performed and it was shown that the laparoscopic approach is safe and feasible. However, the laparoscopic method has the risk of intraabdominal contamination, when the gastric bezoar is retrieved from the gastric lumen in the peritoneal cavity. We developed and applied a new procedure for the removal of the gastric bezoar using one surgical glove and two wound retractors as a fashion of intragastric single port surgery. Herein we present this new minimal invasive procedure, so named "hybrid access surgery" which involves the use of existing devices and overcomes the weakness of laparoscopic removal of the gastric bezoar. Our new procedure, combining the concept of intragastric and single port access, is acceptable and feasible to retrieve the gastric bezoar. In the future, this procedure may be one of the alternative procedures for retrieving gastric bezoar even when it is incarcerated in the pylorus.
