PURPOSE: To characterize the MR findings of hypoxic-ischemic brain injury and to assess the value of the MR imaging. MATERIALS AND METHODS: SE T1 -, T2-weighted, and IR brain MR images of 44 infants and children with the past history of perinatal hypoxic insults were reviewed. Abnormal brain MR findings of 8 patients with birth history of prematurity and 36 patients with birth history of full-term/posterm including 7 with severe anoxic insult history, were compared in regard to the location and the character of the lesions RESULTS: MRI demonstrated the followings;(1)abnormal signal intensity lesions of subcortical and/or deep cerebral white matter, cortex, and deep gray matter, (2)atrophy of the cerebral white matter, cortex and corpus callosum, with/without ventriculomegaly, and (3)delay in myelination. Periventricular and deep white matter lesions were demonstrated in the prematurity, the deep white matter lesions and/or subcortical white matter lesions in the term/post-term, and deep gray matter lesions in the 7 patients with severe anoxic insults history. CONCLUSION: MR imaging was useful in the diagnosis of the hypoxic-ischemic brain injury, and the white and gray matter lesions were correlated with the time of the injury and the severity of hypoxic insult.

PURPOSE: This study was performed to investigate the epidemiology of enterovirus (EV) infections in children at a secondary hospital during recent 5 years. METHODS: We collected the cerebrospinal fluid, stool and throat swab samples from the pediatric patients with suspected EV infections in KEPCO Medical Center, Seoul, Korea from July 2006 to September 2010. EV detection and genotype identification were performed by RT-PCR at Korea Centers for Disease Control and Prevention. RESULTS: A total of 386 samples were collected from 277 patients during study period. Ninety-eight patients (35.4%) were diagnosed with EV infections. The RT-PCR positive rate was the highest in throat swab samples (48.3%). The median age of patient was 4.7 years (range, 0.1-12.5 years). Aseptic meningitis (50, 51.0%) was the most common clinical manifestation; herpangina (22, 22.4%) and hand-foot-mouth disease (18, 18.4%). One hundred EVs were isolated from 98 patients and 20 genotypes of EV were identified; Echovirus 30 (28 cases, 28%), Enterovirus 71 (12 cases, 12%), Echovirus 25 (10 cases, 10%), Echovirus 9 (9 cases, 9%) and Coxsackievirus A6 (8 cases, 8%). Aseptic meningitis caused by Echovirus 30 was the most common manifestation in 2008. There was no complicated case caused by Enterovirus 71. CONCLUSION: This study showed the epidemiology of confirmed EV infection in children from 2006 to 2010. There is a need for continuous surveillance of EV infections and its clinical manifestations.

OBJECTIVES: The purpose of this study was to investigate the clinical characteristics of "fake bad" and "fake good" patients with traumatic head injury in neuropsychological tests. METHODS: We measured subjective symptoms by SCL-90-R and objective symptoms by McBride obstacle-valuation measure. The patient was divided into three groups according to differences between subjective and objective symptoms. We also examined their intelligence, memory, clinical characteristics, using K-WAIS, K-MAS, MMPI. RESULTS: The group who overly expressed their subjective symptoms has its psychotic symptom exaggeratingly measured, so it will be helpful to be careful to such over-expressed symptoms in those who present a psychotic symptom in a clinical view-point. An K-WAIS measurement among those who exaggerated their subjective symptoms showed less value than the actual one, which weakens the reliability of this intelligent test. Rather, for that group, the result of K-MAS can be used with a confidence in the estimation of their severity of symptoms. CONCLUSION: MMPI and neuropsychological tests are helpful to understand characteristics between subjective symptoms and objective disabilities of patients with traumatic head injury.

BACKGROUND: The presence of diastolic mitral regurgitation has been described in patients with complete atrioventricular(AV) block, aortic valve regurgitation, hypertrophic and restrictive cardiomyopathy, and in patients with long diastolic filling period in atrial fibrillation. However, because of rare incidence and difficulty in making diagnosis of this phenomenon, the frequency and hemodynamic effects of diastolic AV valve regurgitation(DAVVR) and relationship of electrocardiographic(ECG) parameters with DAVVR in patients with complete heart block have not been reported in Korea. METHODS: To evaluate the frequency, hemodynamic effects of DAVVR and relation of ECG parameters with DAVVR in patients with complete AV block, we studied 14 consecutive patients with complete AV block by means of two dimensional and Doppper echocardiography. RESULTS: The DAVVR was observed in all cases of complete AV block except 3 cases on temporary pacemaker. The peak velocy of diastolic mitral and tricuspid valve regurgitaton were 105+/-23cm/sec and 98+/-30cm/sec, respectively. The peak and mean pressure gradient of diastolic mitral regurgitation were 4.7+/-1.7mmHg and 3.1+/-1.5mmHg respectively, and the peak and mean pressure gradient of diastolic tricuspid regurgitation were 4.1+/-2.6mmHg and 2.7+/-2.1mmHg, respectively. There was regular interval between p-wave of ECG and onset of diastolic AV valve regurgitation, which was 215+/-12msec, Diastolic AV valve regurgitation disappeared immediately after recovery of complete AV block to sinus rhythm or insertion of DDD-type permanent pacemaker in all cases. CONCLUSION: In Conclusion, the DAVVR was observed in all cases of complete AV block except cases on temporary pacemaker insertion and its hemodynamic effect was mild. There was regular interval between p-wave of ECG and the onset of diastolic AV valve regurgitation.

OBJECTIVES: This study investigated regional disparities in the incidence of 8 major cancers at the municipal level in Korea during 1999-2018 and evaluated the presence or absence of hot spots of cancer clusters during 2014-2018. METHODS: The Korea National Cancer Incidence Database was used. Age-standardized incidence rates were calculated by gender and region at the municipal level for 4 periods of 5 years and 8 cancer types. Regional disparities were calculated as both absolute and relative measures. The possibility of clusters was examined using global Moran’s I with a spatial weight matrix based on adjacency or distance. RESULTS: Regional disparities varied depending on cancer type and gender during the 20-year study period. For men, the regional disparities of stomach, colon and rectum, lung, and liver cancer declined, and those of thyroid and prostate cancer recently decreased, despite an overall increasing incidence. For women, regional disparities in stomach, colon and rectum, lung, liver, and cervical cancer declined, that of thyroid cancer recently decreased, despite an overall increasing incidence, and that of breast cancer steadily increased. In 2014-2018, breast cancer (I, 0.61; 95% confidence interval [CI], 0.53 to 0.70) showed a high probability of cancer clusters in women, and liver cancer (I, 0.48; 95% CI, 0.40 to 0.56) showed a high probability of cancer clusters in men. CONCLUSIONS Disparities in cancer incidence that were not seen at the national level were discovered at the municipal level. These results could provide important directions for planning and implementing local cancer policies.

Acute intermittent porphyria (AIP) is a rare disorder characterized biochemically by the increased excretion of porphyrins and porphyrin precursors, including delta-aminolevulinic acid (ALA) and porphobilinogen (PBG). AIP has variable clinical manifestations, such as acute abdominal pain, vomiting, nausea, constipation, peripheral neuropathy, seizures, tachycardia, and hypertension. A 16-year-old girl presented with recurrent abdominal pain, vomiting, hypertension, seizures, hypercholesterolemia, and red urine. AIP was confirmed by clinical features and increased 24-hour urine ALA and PBG. AIP should be considered in the differential diagnosis of patients who have abdominal pain, hypertension, and seizures when the results of all other tests are normal.

Myofascial pain syndrome is defined as the sensory, motor and autonomic symptoms caused by the myofascial trigger points. The sternocleidomastoid muscle is a complex muscle that frequently contains multiple trigger points. These trigger points cause symptoms that are easily misdiagnosed as other conditions. Earache of unexplained origin is likely to be caused by trigger points in the clavicular division of the sternocleidomastiod muscle. The authors report a case of earache caused by a trigger point in the sternocleidomastoid muscle. A 34 year-old woman had earache without any history of trauma or infection. The patient did not have any abnormal finding by otolaryngologic testing, except for an earache, which had not subsided. On physical examination, trigger points in the clavicular division of the sternocleidomastiod muscle were found, and the earache was successfully treated by trigger point injections.

Nephrotic syndrome in childhood is known to be associated with a hypercoagulable state and thromboembolic complications, among which cerebral venous thrombosis is a very rare and serious one, with only a few isolated reports in the literature. A 9-year-old boy with known nephrotic syndrome was admitted due to a relapse with massive proteinuria and generalized edema. He complained of a prolonged frontal headache. The enhanced brain magnetic resonance imaging(MRI) showed a high signal in the region of the superior sagittal sinus and right transverse sinus consistent with a thrombus. He was managed with steroids, cyclosporine and warfarin. His headache subsided 2 weeks later and proteinuria resolved 1 month later. An MRI 2 months later was normal. We describe this case and review the literature to emphasize the importance of recognizing this potentially life threatening complication and initiating anticoagulation therapy.

BACKGROUND: Postoperative nausea and vomiting (PONV), postanesthetic shivering and pain are common postoperative patient complaints that can result in adverse physical and psychological outcomes. Some antiemetics are reported to be effective in the management of postoperative pain and shivering, as well as PONV. We evaluated the efficacy of dexamethasone added to ramosetron on PONV, shivering and pain after thyroid surgery. METHODS: One hundred and eight patients scheduled for thyroid surgery were randomly allocated to three different groups: the control group (group C, n = 36), the ramosetron group (group R, n = 36), or the ramosetron plus dexamethasone group (group RD, n = 36). The patients were treated intravenously with 1 and 2 ml of 0.9% NaCl (group C); or 2 ml of 0.15 mg/ml ramosetron plus 1 ml of 0.9% NaCl (group R); or 2 ml of 0.15 mg/ml ramosetron plus 1 ml of 5 mg/ml dexamethasone (group RD) immediately after anesthesia. RESULTS: Incidence of nausea and the need for rescue antiemetics, verbal rating scale (VRS) 1 hour pain value, ketorolac consumption, and incidence of shivering were significantly lower in group R and group RD, than in group C (P < 0.05). Moreover, these parameters were significantly lower in group RD than in group R (P < 0.05). CONCLUSIONS: Combination of ramosetron and dexamethasone significantly reduced not only the incidence of nausea and need for rescue antiemetics, but also the VRS 1 hour pain value, ketorolac consumption, and the incidence of shivering compared to ramosetron alone in patients undergoing thyroid surgery.
