BACKGROUND: The improved technique for cardiopulmonary resuscitation(CPR) has resulted in the survival of many patient who experienced cardiac arrest. However, mortality in resuscitated patients is high, and the survival rate without brain damage is very low. Various neurological examination models, neuro-imaging techniques, electrophysiological procedures, and biochemical tests have been studied with respect to the detection of cerebral damage and outcome, but an early, reliable prediction of individual outcomes is still uncertain. METHODS: We studied twenty patient who had been in a coma for more than 24 hours after CPR, Somatosensory evoked potentials(SEP) were measured within the first three days after CPR. RESULTS: Of the twenty patients, seven patients(35%) had a good outcome, and thirteen patients(65%) had a bad outcome. Of the eleven patients with loss of the cortical evoked potential's N20 peak, all had a bad outcome. CONCLUSION: SEPs are of great benefit in prognostic evaluation after CPR.

BACKGROUND: Various tools for the acute response system (ARS) predict and prevent acute deterioration in pediatric patients. However, detailed criteria have not been clarified. Thus we evaluated the effectiveness of bradycardia as a single parameter in pediatric ARS. METHODS: This retrospective study included patients who had visited a tertiary care children's hospital from January 2012 to June 2013, in whom ARS was activated because of bradycardia. Patient's medical records were reviewed for clinical characteristics, cardiologic evaluations, and reversible causes that affect heart rate. RESULTS: Of 271 cases, 261 (96%) had ARS activation by bradycardia alone with favorable outcomes. Evaluations and interventions were performed in 165 (64.5%) and 13 cases (6.6%) respectively. All patients in whom ARS was activated owing to bradycardia and another criteria underwent evaluation, unlike those with bradycardia alone (100.0% vs. 63.2%, p = 0.016). Electrocardiograms were evaluated in 233 (86%) cases: arrhythmias were due to borderline QT prolongation and atrioventricular block (1st and 2nd-degree) in 25 cases (9.2%). Bradycardia-related causes were reversible in 202 patients (74.5%). Specific causes were different in departments at admission. Patients admitted to the hemato-oncology department required ARS activation during the night (69.3%, p = 0.03), those to the endocrinology department required ARS activation because of medication (72.4%, p < 0.001), and those to the gastroenterology department had low body mass indexes (32%, p = 0.01). CONCLUSIONS: Using bradycardia alone in pediatric ARS is not useful, because of its low specificity and poor predictive ability for deterioration. However, bradycardia can be applied to ARS concurrently with other parameters.

A 53-year-old man developed some erythematous follicular macules accompanied with tingling sensation on both shoulders. Histologic finding showed a dense lymphocytic infiltrate around the infundibular portion of the follicle, where separation of the dermoepidermal junction was seen. The insect, obtained from the skin lesion, was identified as a larva of an Ap- hid

BACKGROUND: It is well known that systemic blood pressure oscillates with low(0.04~0.1Hz), mid(0.1~0.15Hz), and high(respiratory) frequency range. But there has been no study about oscillation of pulmonary artery pressure(PAP). METHOD: We measured PAP for 5 minutes in 32 patients of ventricular septal defect and stored them to computer files. Power spectral density curve was obtained. Low, mid, respiratory frequency power were measured by integrating the area within each frequency range below the power density curve. RESULT: The incidence of significant low frequency power(more than 5% of total power) were higher in patients of high PAP and hign Rp/Rs than those of low PAP and Rp/Rs(p<0.01 and p<0.005 respectively). The low frequency power positively correlates with PAP and Rp/Rs(r=0.62, p<0.0005 and r=0.61, p=0.0005 respectively). CONCLUSION: It can be said conclusively that as PAP and pulmonary vascular resistance elevates, the PAP tends to definitively oscillate in low frequency range.

The 8th Korean case of human thelaziasis was recorded with the description of the most probable source of infection of the case. The patient was 23-year-old Korean Army soldier who had been in mountainous vicinity of Seoul for 6 months and complained of moving foreign body sensation, photophobia and epiphora of the left eye during past 7 days before the ophthalmological consultation. Total 3 worms were removed from the eye, two by a friend, one by the ophthalmologist. The latter one waS parasitologically identified as a female worm of Thelazia callipaeda. The dogs in the military compound were examined and one eye of them was found to be infected with 11 male and 20 female of oriental eye worms under the nictitating membrane. The significance of dog as a reservoir host of T. callipaeda infection was discussed.
