The aim of this study was to evaluate the risk factors of recurrences after their first febrile convulsions in infants and young children. Dlinical studies were made on 187 cases of febrile convulsions who were admitted to the Department of pediatrics of wallace Memorial Baptist Hospital from March, 1990 to December, 1992. 1) 63 cases of 187 cases had recurrences after their febrile convulsions. Thus, the recurrence rate was 33.7%. 2) The male to female ratio was 2.1:1. And there were no significant differences in recurrence rates between sexes. 3) The recurrence rate was significantly higher in those whose initial febrile convulsions were developed before first 18 months of life than those whose initial convulsions were after 18 months of age (49.5% vs. 12.5%). 4) The time interval from initial attack to recurrence was within 12 months in 80% of cases. 5) Our study revealed that the seizure characteristics of the initial febrile convulsion are not important as predictive factors about the probability of recurrences. 6) Among the total 187 cases, family history were present in 52 cases (27.8%). And there were significantly higher recurrence rates if their families show the same history of febrile convulsion (63.5% vs. 22.2%). 7) The risk of recurrence was much higher in patients whose first febrile history of febrile convulsion at the same time.

4.Risk Factors and Prognosis of Isolated Ischemic 3rd, 4th, 6th Cranial Nerve Palsy.
Journal of the Korean Ophthalmological Society 2014;55(5):740-745
PURPOSE: To investigate the clinical features and risk factors of ischemic third, fourth, sixth cranial nerve palsy. METHODS: Retrospectively, we reviewed the medical records of 46 eyes of 46 patients who were diagnosed with ischemic third, fourth, sixth nerve palsy alone such as age of onset, risk factors, recovery rate and recovery time. RESULTS: The mean age of onset was 64.9 years. Of the 46 patients, 15 patients (32.6%) in third cranial nerve palsy group, 15 patients (32.6%) in fourth cranial nerve palsy group, 16 patients (34.8%) in sixth cranial nerve palsy group. The risk factor of hypertension in 30 patients (65.2%) was the most common than other risk factors such as diabetes, hyperlipidemia, elevated blood hematocrit, ischemic heart disease, left ventricular hypertrophy, smoking. The mean number of risk factors was 2.3 +/- 0.5 in third cranial nerve palsy group, 1.6 +/- 1.1 in sixth cranial nerve palsy group, 1.4 +/- 1.1 in fourth cranial nerve palsy group. Of the 46 patients, 42 patients (91.3%) were recovered. There was no significant difference in recovery rate by cranial nerve palsy. Recovery time of intracranial abnormalities group (10.5 +/- 2.9 weeks) in brain imaging study was late as compared with that of no intracranial abnormalities group (7.5 +/- 5.1 weeks). CONCLUSIONS: The overall recovery rate of isolated ischemic third, fourth, sixth cranial nerve was high. But if there are intracranial abnormalities in imaging study, it took a long time to recover. Also ischemic third cranial nerve palsy had multiple risk factors characteristically.

OBJECTIVE: Amniocentesis is the most commonly used invasive method for prenatal diagnosis of genetic disorders. We performed this study to analyze the indications, distributions of maternal age and cytogenetic results of midtrimester amniocentesis. METHODS: We retrospectively analyzed 785 cases of midtrimester prenatal genetic amniocentesis which were performed in the cytogenetics laboratory using in situ coverslip culture at Dong-A University Hospital from January 1995 to March 2003. RESULTS: Amniocentesis was practiced mostly from 15 weeks to 20 weeks of gestational ages. Requested indications of amniocentesis were abnormal maternal serum screening (421, 53.7%), advanced maternal age (233, 29.7%) and abnormal ultrasonographic finding (61, 7.8%) in the order of decrease. The overall incidence of chromosome abnormalities was 5.1% (40 cases), and it contains 27 cases (3.4%) of numerical abnormalities and 13 cases (1.7%) of structural abnormalities. Among autosomal abnormalities Down syndrome was most common (13 cases) and followed by Edward syndrome (2 cases). Of the sex chromosomal abnormalities, three cases of Turner syndrome and three cases of Kleinefelter syndrome were found. Chromosomal abnormalities were most frequently noted in the maternal age of 30 to 34 years old (14 cases, 35.0%), 25 to 29 years old (12 cases, 30.0%), followed by 35 to 39 years old (7 cases, 17.5%). The frequency of pseudomosaicism were 5 cases (0.6%). CONCLUSION: Maternal serum screening, advanced maternal age and antenatal ultrasonographic finding must be important screening methods for amniocentesis which is considered to the most effective diagnostic procecdure for prenatal cytogenetic studies. I conclude that the karyotyping analysis of midtrimester amniocentesis is efficacious method for detection of chromosomal aberration and genetic counselling for parents.

A patients with atlantoaixial instability and osodontoideum underwent atlantoaixial fusion (Harms and Melcher technique) with demineralized bone matrix. But, unfortunately, the both pedicle screws in C2 were fractured within 9 weeks follow-up periods after several suspected episode of neck hyper-flexion. Fractured screws were not contact to occipital bone in several imaging studies, but it could irritate the occipital bone when neck extension because the relatively close distance between the occipital bone and C1 posterior arch. The patient underwent revision operation with translaminar screw fixation with autologus iliac bone graft. Postsurgical course were uneventful except donor site pain, but the bony fusion was not satisfied after 4 months follow-up. The patient re-underwent revision operation in other hospital. Continuous complication after atlantoaixial fusion is rare, but the clinical course could be unlucky to patients. Postoperative immobilization could be important to prevent the unintended clinical course of patients.

OBJECTIVE: A general orientation along the cervical spine could be estimated by external landmarks, and it was useful, quick and less exposable to radiation, but, sometimes it gave reference confusion of target cervical level. The authors reviewed the corresponding between the neck external landmarks and cervical levels. METHODS: Totally 1,031 cervical lateral radiographs of different patients were reviewed in single university hospital. Its compositions were 534 of males and 497 females; 86 of second decades (10-19 years-old), 169 of third decades, 159 of fourth decades, 209 of fifth decades, 275 of sixth decades, and 133 of more than seventh decades (>60 years-old). Reference external landmarks (mandible, hyoid bone, thyroid cartilage, and cricothyroid membrane) with compounding factors were reviewed. RESULTS: The reference levels of cervical landmarks were C2.13 with mandible angle, C3.54 with hyoid bone, C5.12 with thyroid cartilage, and C6.01 with cricothyroid membrane. The reference levels of cervical landmarks were differently observed by sex, age, and somatometric measurement (height) accordingly mandible angle from C1 to C3, hyoid bone from disc level of C2 and C3 to C5, thyroid cartilage from disc level of C3 and C4 to C7, and cricothyroid membrane from C4 to disc level of C7 and T1. CONCLUSION: Surface landmarks only provide general reference points, but not correspond to exact levels of the cervical spine. Intraoperative fluoroscopy ensures a more precise placement to the targeted cervical level.

Congenital complete atrioventricular (AV) block is a rare neonatal disease. It is a passively acquired immune-mediated injury of the conduction system, triggered by transplacental passage of maternal anti-SSA/Ro and anti-SSB/La antibodies. Management of premature infants with symptomatic complete AV block is challenging. If medical treatment with a β-adrenergic agonist and inotropic drugs is not effective, early cardiac pacing should be considered. Here we report a case of congenital complete AV block in a low birth weight, preterm neonate, who was successfully treated with temporary transcutaneous pacing immediately after birth. Temporary transcutaneous pacing may be an option for the emergent management of a low birth weight preterm neonate with congenital complete AV block prior to permanent pacemaker implantation.

Korean Journal of Ophthalmology 2009;23(1):40-42
PURPOSE: To maximize effective use of mydriatic drugs through comparing the pupillary dilation effects between 1% tropicamide and 2.5% phenylephrine. METHODS: Fifty people requiring pupillary dilation were divided into 3 groups. Group 1 was treated with one drop of 1% tropicamide in the right eye and one drop of 2.5% phenylephrine in the left eye. Group 2 was treated twice during a 5-minute interval with 1% tropicamide in the right eye. Group 3 was treated twice during a 5-minute interval with 2.5% phenylephrine in the right eye. Groups 2 and 3 were treated with 2.5% phenylephrine and 1% tropicamide in the left eye, administered during a 5-minute interval. The pupillary size was measured in all groups for 40 minutes following eye drops administration. RESULTS: The mean patient age was 15.7 years. Group 1 included 10 patients, and groups 2 and 3 included 20 patients each. Eight patients in group 1 and 16 patients in group 2 developed a larger right pupil. Fourteen patients in group 3 developed a larger left pupil. CONCLUSIONS: Our study showed that 1% tropicamide, with its parasympathetic antagonistic mechanism of action, was more effective at inducing pupillary dilation than 2.5% phenylephrine, and the combination of 1% tropicamide and 2.5% phenylephrine was more effective than multiple drops of single eye drops.
