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.

Abnormal position of the scrotum is usually associated with severe proximal hypospadias. Up to now, surgical correction of scrotal transposition usually ends with the urethral meatus in the perineum or penoscrotal junction. We present an experience of total reconstruction of incomplete scrotal transposition, superficial chordee and perineal hypospadias in a child with a previously repaired imperforate anus. This patient had minor complications such as small fistula at penoscrotal junction, skin necrosis around the neomeatus, superficial wound infection, all the which healed expectantly in a month.

Osteomalacia is a disorder in which the mineralization of the organic matrix of the skeleton is defective. Proximal muscular weakness is a common symptom of osteomalacia. A 27-year-old woman reported the gradual onset of gait disturbance and bone pain in the thigh. Her height shortened during 10 months. On neurological examinations, proximal muscular weakness of the extremities was disclosed. Serum phosphorus was 1.8 mg/dl (normal 2.5~4.5), alkaline phosphatase was 1045 IU/L (normal 70~290), and 1,25 (OH)2 vitamin D3 was 18 pg/ml (normal 20~60). On roentgenography, multiple pseudofracture lines of the rib and erosion of the head of the right femur were demonstrated. A bone scan showed multiple hot spots on the ribs and right femur. She was medicated with calcitriol and phosphorus and she recovered most of her strength and experienced decreased bone pain after 3 months. We report a case that confirms osteomalacic myopathy by an endocrinological test in patients who experienced gradual proximal muscular weakness and bone pain.

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.

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
