Thirty consecutive patient seen in a pediatric out patient and emergency department, in whom the diagnosis of intussusception was considered, had an ultrasound examination of the abdomen before the barium enema. The peak age was 5~12 month (range 4~34 month). Intussusception was detected by ultrasonography in all 25 cases proved by barium enema (sensitivity 100%). Normal findings on ultrasonography correlated with a negative barium enema results in 5 of 5 cases (negative predictive value=100%). No intussusception was missed by ultrasonography. To determine which patient would most benefit from ultrasonography, we divided patients into either a high risk group (100% intussusception) or a low risk group (37.5% intussusception) on the basis of clinical symptoms. We conclude that ultrasonography can be used as a rapid sensitive screening procedure in the diagnosis or exclusion of childhood intussusception. Probability of surgical reduction was associated with size of of total thickness and external rim thickness.

BACKGROUND AND OBJECTIVES: There is little data to indicate that hypertrophy of adenoid and tonsil may cause short stature. However, there is no data relating short stature to allergic rhinitis in the Korean population. The aim of this study was to investigate the effect of hypertrophy of adenoid and tonsil and allergic rhinitis on children with short stature. SUBJECTS AND METHOD: One hundred and ninety-one children were included in the disease group, which consisted of three groups, allergic rhinitis only (n=83), hypertrophy of adenoid and tonsil only (n=67), and combintorial of allergic rhinitis and hypertrophy of adenoid and tonsil (n=41). There were 174 pediatric patients in the control group. Growth hormone levels, thyroid function and both wrist X-rays were checked on the children with short stature in order to exclude other chief medical problems causing short stature. For the purpose of evaluating the relationship between short stature and clinical factors, allergy parameters, eosinophil partition rate and total IgE levels were checked in the allergic rhinitis group, and the size of the adenoid and tonsil were checked in the adenoid and tonsil hypertrophy group. The relationship between the incidence of short stature and above clinical factors was evaluated. RESULTS: The incidence of short stature was significantly higher in each disease group than in the control. However, there was no statistically significant differences between each disease group. The above clinical factors were not associated with short stature. CONCLUSION: Hypertrophy in adenoid and tonsil and allergic rhinitis might be an independent cause of short stature.

Human respiratory syncytial virus (HRSV) is known as the leading cause of respiratory tract illness in infancy and elderly children worldwide. We investigate the prevalence pattern and genetic characteristics in the second variable region G protein gene of HRSV during 5 consecutive seasons from 2010 to 2015. A total of 4,793 specimens (throat swabs) were collected from patients with acute respiratory tract. HRSV were evaluated and classified as HRSV A (n=111) or HRSV B (n=64) by real-time RT-PCR or RT-PCR. In general HRSV were detected in winter season. Coughing, fever, rhinorrhea and sputum were confirmed main symptoms in patients with HRSV. There were no significant differences in clinical characteristics or severity according to the HRSV subgroup infections. Out of 175 HRSV positive samples, 94 samples were successfully sequenced using G gene. Phylogenetic analysis revealed that 62 HRSV-A strains clustered into genotypes ON1 (n=54, 87.1%), NA1 (n=7), NA2 (n=1) and 32 HRSV-B strains clustered into three genotypes: BA4 (n=28, 87.5%), BA5 (n=2), BA6 (n=2). These results provide a better understanding of HRSV prevalence pattern and genetic characteristics.

Diagnosing pseudoaneurysms of the popliteal artery is usually straightforward in physical examinations and imaging findings. However, when a pseudoaneurysm shows a soft tissue mass with adjacent osseous change, it can mimic a bone tumor or a soft tissue sarcoma. We present a case of a 65-year-old man who had a pseudoaneurysm of the popliteal artery showing soft tissue mass and insinuating into the intramedullary cavity of the tibia. This presented case emphasizes the importance of considering pseudoaneurysms in the differential diagnosis of an apparent soft tissue mass with pressure erosion in adjacent bone.

PURPOSE: Cervical lymph node metastasis in patients with papillary thyroid microcarcinoma (PTMC) is associated with an increased recurrence rate and distant metastases. In this study, we analyzed the predictive factors of lateral metastasis in patients with PTMC. METHODS: We retrospectively reviewed the medical records of 1,030 patients with PTMC who underwent thyroidectomy. The clinicopathological characteristics and radiological findings upon ultrasonography (US) and computed tomography (CT) were then analyzed to evaluate the predictability of lateral metastasis of PTMC. RESULTS: The overall rate of lateral metastasis was 3.3% for the 1,030 patients with PTMC. All patients underwent central lymph node dissection (CLND), and 119 of these patients (11.6%) underwent either prophylactic or therapeutic selective neck dissection (SND). Among patients who underwent lateral node evaluation, 28.6% had lateral metastasis. We found that lateral metastasis was associated with larger tumor size, extrathyroidal extension, multiple tumors, bilateral tumors, CLN metastasis, and positive expression of thyroid peroxidase. Positive findings of CLN and lateral metastases on ultrasonography (US) and computed tomography (CT) were significantly associated with lateral metastasis. CONCLUSION: This study demonstrated that, for patients with PTMC, larger tumor size, extrathyroidal extension, multiple tumors, bilateral tumors, CLN metastasis, positive expression of thyroid peroxidase, and positive CLN and lateral metastases identified on US and CT were significantly associated with lateral metastasis. Further studies with a large prospective study and longer follow-up are needed to clarify the predictive value of these factors.

PURPOSE: To study the influence of age, gender, refractive error, and optic disc size on the optic disc parameters measured with the Heidelberg Retina Tomograph (HRT; software 2.01) in normal eyes. METHODS: Ninety-two normal subjects (mean refractive error +/- SD: -0.15 +/- 1.64 D, range -6.63 to +3.38 D) were examined using HRT. The influence of age, refraction, and disc area on each parameter was analysed by multiple linear regression. RESULTS: Large discs had large values of cup area, cup volume, rim area, cup to disc area ratio, and mean cup depth. Large discs had small values of rim to disc area ratio. However, rim volume, maximum cup depth, cup shape measure, height variation contour, mean retinal nerve fiber layer thickness, and retinal nerve fiber layer cross-sectional area were not related to disc area. Most parameters were independent of age or refractive error except for a few parameters. Age was weakly related to disc area. Refractive error was weakly associated with cup shape measure. Gender had no statistically significant influence on optic disc parameters. CONCLUSIONS: These results indicate that several optic disc parameters have better correlations with the optic disc area than age, gender, and refractive error. These differences must be considered in the evaluation of optic disc for glaucoma.

Primary diffuse leptomeningeal gliomatosis (PDLG) is a rare condition with a fatal outcome, characterized by diffuse infiltration of the leptomeninges by neoplastic glial cells without evidence of primary tumor in the brain or spinal cord parenchyma. In particular, PDLG histologically diagnosed as gliosarcoma is extremely rare, with only 2 cases reported to date. We report a case of primary diffuse leptomeningeal gliosarcomatosis. A 68-year-old man presented with fever, chilling, headache, and a brief episode of mental deterioration. Initial T1-weighted post-contrast brain magnetic resonance imaging (MRI) showed diffuse leptomeningeal enhancement without a definite intraparenchymal lesion. Based on clinical and imaging findings, antiviral treatment was initiated. Despite the treatment, the patient's neurologic symptoms and mental status progressively deteriorated and follow-up MRI showed rapid progression of the disease. A meningeal biopsy revealed gliosarcoma and was conclusive for the diagnosis of primary diffuse leptomeningeal gliosarcomatosis. We suggest the inclusion of PDLG in the potential differential diagnosis of patients who present with nonspecific neurologic symptoms in the presence of leptomeningeal involvement on MRI.

BACKGROUND: This study aimed to compare analgesic efficacy and occurance of motor block and other side effects of a 48 hr postoperative continuous epidural infusion of 0.125% bupivacaine or ropivacaine with morphine. METHODS: Forty patients undergoing a Cesarean section were allocated randomly into two groups. Both groups received an epidural injection of 2.0% lidocaine 18 20 ml and 0.5% bupivacaine 2 5 ml with fentanyl 50microgram 20 minutes before surgical incision and received 2 mg of epidural morphine by bolus 40 minutes after surgical incision. For post-operative pain control, a continuous epidural infusion was started using a two day infusor containing 6 mg of morphine in 100 ml of 0.125% bupivacaine (Group 1, n = 20) or 100 ml of 0.125% ropivacaine (Group 2, n = 20). Visual analog scale (VAS) for pain during rest and movement, sensory change and motor blockade were assessed for 48 hrs. after surgery. RESULTS: There were no significant differences in VAS for pain during rest and movement. The incidences of side effect were similar in both groups. CONCLUSIONS: Using 0.125% bupivacaine with morphine via the epidural route provided similar pain relief and side effects as 0.125% ropivacaine with morphine.
