OBJECTIVES: The purpose of this study was to examine the food allergy-related knowledge, awareness, and performance of dietitians at children's hospitals, depending on whether or not they have a clinical dietitian certificate.METHODS: A questionnaire survey was administered to 41 dieticians at children's hospitals registered as a part of the Korean Hospital Association. The survey consisted of questionnaires examining general characteristics, nutritional counseling-related characteristics, and food allergy-related characteristics (food allergy-related knowledge, awareness, and performance). We examined differences according to the status of clinical dietitian certification.RESULTS: The proportion of subjects who were holders of clinical dietitian certificates was 48.8%. There were differences between holders of clinical dietitian certificates and non-holders as follows. Regarding nutritional awareness and performance, ‘needs to provide nutrition counseling in children's hospitals’, ‘providing nutrition counseling services in working hospitals’, and ‘whether there is a nutrition counseling room’ scored higher among holders of clinical dietitian certificates than non-holders. Holders of clinical dietitian certificates showed higher scores for knowledge of food allergy symptoms and food allergy management than non-holders. For food allergy awareness and performance, ‘self-assessment of food allergy knowledge understanding level’, ‘awareness of open oral food challenge (OFC)’, ‘recognition of the need for education and counseling on food allergy for patients/guardians’, and ‘food allergy related educational experience’ scored higher among holders of clinical dietitians certificates than in non-holders.CONCLUSIONS: Children's hospital dietitians with a clinical dietitian certificate showed high knowledge, awareness, and performance related to food allergies. It is thus necessary to employ a clinical dietitian for food allergy management in children's hospitals. In addition, training and conservative education are necessary for the management of food allergies for children's hospital dietitians.

OBJECTIVE: To compare perioperative outcome of robot-assisted radical hysterectomy with abdominal radical hysterectomy for early-stage cervical cancer and endometrial cancer and to evaluate the feasibility of robotic-assisted radical hysterectomy. METHODS: We reviewed medical record of 37 patients who had radical hysterectomy at Hallym university for cervical cancer stage Ia1 to IIa and endometrial cancer stage Ia to Ib. Abdominal radical hysterectomy was carried out in 27 (Abdominal group) patients and robot-assisted radical hysterectomy carried out in 10 patients (Robotic group). We compared patient's characteristics between two groups. Perioperative characteristics compared included cancer stage, operative time, number of nodes, estimated blood loss, length of hospital stay and complications. RESULTS: There were no differences in age, parity, history of medical disease, body mass index between two groups (p>0.05). Robotic operative times were significantly longer than for abdominal (480.0+/-117.8 vs. 286.9+/-65.6 min, p<0.0001). Blood loss (660.0+/-245.9 vs. 1,137.0+/-608.4 mL. p<0.0001) and length of hospital stay (7.2 versus 17.1 days, p<0.0001) were significantly lower for the robotic group. Lymph node yield in the robotic group was equivalent to that for the abdominal group (30.1+/-8.7 vs. 35.4+/-16.9, p=0.356). No major operative complications occurred with both groups. CONCLUSION: Robot-assisted radical hysterectomy appears safe and feasible in early-stage cervical and endometrial cancer.

OBJECTIVE: Density of the chronic subdural hematoma (cSDH) is variable. It often appears to be mixed density. Multiple densities of cSDH may result from multiple episodes of trauma. We investigated the frequency of mixed density and the causes of head injuries representing each density. METHODS: We could collect 242 cases of chronic SDH. The cSDHs were classified into four groups; hypodensity, homogeneous isodensity, layered type, and mixed type on the basis of CT scans. RESULTS: The density of cSDH was isodense in 115 patients, hypodense in 31 patients, mixed in 79 cases, and layered in 17 cases. The cSDH was on the left side in 115 patients, on the right side in 70 patients, and bilateral in 40 patients. The history of trauma was identifiable in 122 patients. The etiology could be identified in 67.7% of the hypodense hematomas, while it was obscure in 59.5% of the mixed hematomas. CONCLUSION: Mixed density of cSDH results from multiple episodes of trauma, usually in the aged. It is hard to remember all the trivial traumas for the patients with the mixed density cSDHs. Although there were membranes within the mixed density hematomas, burr-holes were usually enough to drain the hematomas.

BACKGROUND AND PURPOSE: The detection of alpha-synuclein in the body fluids of patients with synucleinopathy has yielded promising but inconclusive results, in part because of conformational changes of alpha-synuclein in response to environmental conditions. The aim of this study was to determine the feasibility of using alpha-synuclein as a biological marker for Parkinson's disease (PD). METHODS: Twenty-three drug-naive patients with PD (age 62.4+/-12.7 years, mean+/-SD; 11 males) and 29 age- and sex-matched neurologic control subjects (age 60.1+/-16.2 years; 16 males) were recruited. The levels of oligomeric and total alpha-synuclein in the cerebrospinal fluid (CSF) and plasma were measured using two simultaneous enzyme-linked immunosorbent assays. RESULTS: The level of alpha-synuclein oligomer in the CSF of PD patients was significantly higher in PD patients than in neurological controls, but other findings (plasma alpha-synuclein oligomer and total alpha-synuclein in CSF and plasma) did not differ significantly between the two groups. When the control subjects were divided into a symptomatic control group (11 patients who complained of parkinsonian symptoms and were diagnosed with hydrocephalus and drug-induced or vascular parkinsonism) and a neurologic control group (10 normal subjects and 8 patients with diabetic ophthalmoplegia), the level of alpha-synuclein oligomer in the CSF was still significantly higher in PD patients than in both of the control subgroups. CONCLUSIONS: These findings provide further evidence for a pathogenic role of the alpha-synuclein oligomer and suggest that CSF levels of alpha-synuclein oligomer can be a reliable marker for PD.

The dumping syndrome has been a known complication of gastric surgery in adults, but it is recognized as a very rare disease in the pediatric population, especially in Korea. We report a case of dumping syndrome in a 10-month-old infant, who underwent Nissen fundoplication for the treatment of gastroesophageal reflux(GER). He was admitted because of aspiration pneumonia, and diagnosed as GER by 24-hour ambulatory esophageal pH monitoring test. For the treatment of GER, Nissen fundoplication was performed. After the operation, symptoms occurred within 30 minutes of meals, such as diaphoresis, palpitation, weakness, abdominal fullness, nausea, and diarrhea. The gastric emptying scan showed very rapid gastric emptying. His oral glucose tolerance tests revealed early-onset hyperglycema followed by delayed-onset hypoglycemia, which was the characteristic finding of the dumping syndrome. We introduced uncooked cornstarch to resolve symptoms and maintain the serum glucose level. After the feeding of uncooked cornstarch, his symptoms subsided and normal oral glucose test was restored. After the six months of treatment, his weight and height were increased dramatically from below 3 percentiles up to the normal range. The dumping syndrome should be considered when an infant suffers from the feeding difficulties after the gastric surgery like Nissen fundoplication, and the diet therapy including uncooked cornstarch could be applied as an effective measure.

Lumbar hernia is a relatively rare clinical phenomenon. They may be classified according to their anatomic location and they can be either congenital or acquired. These patients usually present with a protruding bulge in the posterolateral abdominal wall. Portions of the small and large intestine may be found in the sac. This may be asymptomatic or it can become incarcerated and strangulated. We report here on a rare case of secondary lumbar hernia combined with descending colon incarceration. The diagnosis of lumbar hernia was made by CT scan and barium enema. Excision of the sac was performed and the hernial defect in the fascia was repaired with polypropylene mesh reinforcement.

Stent assisted coiling (SAC) is a useful technique for the treatment of wide necked complex aneurysm. As the frequency of SAC increases, stent-related complications such as thromboembolism, aneurysm rupture, and vessel rupture have been reported. However, to the best of our knowledge, carotid-cavernous fistula (CCF) after SAC has never been reported. The authors experienced a case of direct CCF after a SAC procedure for treatment of a complex posterior communicating artery (PCoA) aneurysm regrowth, which was treated by clip ligation 12 years before. The patient was managed conservatively and angiograms performed three months after the procedure showed the complete obliteration of the left PcoA aneurysm and the spontaneous disappearance of CCF. Navigation of Solitaire stent lumen with microcatheter can cause unexpected arterial injury, especially when the proximal tip is placed in the curved portion. It seems to be desirable to place the proximal tip of Solitaire stent in the straight portion whenever possible to reduce the risk of inadvertent arterial injury which might be caused by future navigation of stent lumen.

PURPOSE: To evaluate the correlation between colon transit time (CTT) test value and initial maintenance dose of polyethylene glycol (PEG) 4000 or lactulose. METHODS: Of 415 children with chronic functional constipation, 190 were enrolled based on exclusion criteria using the CTT test, defecation diary, and clinical chart. The CTT test was performed with prior disimpaction. The laxative dose for maintenance was determined on the basis of the defecation diary and clinical chart. The Shapiro-Wilk test and Pearson's and Spearman's correlations were used for statistical analysis. RESULTS: The overall group median value and interquartile range of the CTT test was 43.8 (31.8) hours. The average PEG 4000 dose for maintenance in the overall group was 0.68±0.18 g/kg/d; according to age, the dose was 0.73±0.16 g/kg/d (<8 years), 0.53±0.12 g/kg/d (8 to <12 years), and 0.36±0.05 g/kg/d (12 to 15 years). The dose of lactulose was 1.99±0.43 mL/kg/d (<8 years) or 1.26±0.25 mL/kg/d (8 to <12 years). There was no significant correlation between CTT test value and initial dose of laxative, irrespective of the subgroup (encopresis, abnormal CTT test subtype) for either laxative. Even in the largest group (overall, n=109, younger than 8 years and on PEG 4000), the correlation was weak (Pearson's correlation coefficient [R]=0.268, p=0.005). Within the abnormal transit group, subgroup (n=73, younger than 8 years and on PEG 4000) correlation was weak (R=0.267, p=0.022). CONCLUSION: CTT test value cannot predict the initial maintenance dose of PEG 4000 or lactulose with linear correlation.

OBJECTIVE: The purpose of this study was to evaluate the occurrence rate of diffusion positive lesions (DPLs), and to assess the peri-procedural risk factors for the occurrence of DPLs in patients who underwent coil embolization of cerebral aneurysms. MATERIALS AND METHODS: A total of 304 saccular aneurysms were embolized during a seven-year period from Jan 2007 to Dec 2013. Of these, postoperative diffusion-weighted images were obtained in 186 procedures. There were 100 ruptured aneurysm and 86 unruptured aneurysms. The coiling procedures were as follows: simple coiling in 96, balloon assisted coiling (BAC) in 39, and stent assisted coiling (SAC) in 51 aneurysms. Clinical, angiographic and procedural factors were analyzed in relation to the occurrence of DPLs. RESULTS: Overall, DPLs were observed in 50.5%. In unruptured aneurysms, DPLs occurred in 23.5% of BAC, 41.9% of SAC and 57.7% of simple coiling (p = 0.08). Among ruptured aneurysms, DPLs occurred in 63.6% of BAC, 62.5% of SAC and 54.3% of simple coiling (p = 0.71). DPLs had a tendency to increase in ruptured aneurysms compared with unruptured aneurysms (57% vs. 43%, p = 0.077). Logistic regression analysis revealed that age > 55 years was the only independent risk factor for the occurrence of DPLs. CONCLUSION: DPLs occured more frequently in ruptured aneurysm and at an older age. Although most DPLs are asymptomatic, careful manipulation of cerebral or extracerebral arteries using various endovascular devices is important to reducing the occurrence of DPLs. BAC appeared to reduce occurrence of TE events in patient with unruptured aneurysm.

Menkes disease (also known as kinky hair disease) is an X-linked recessive neurodegenerative disorder caused by diverse mutations in a copper-transport gene, ATP7A. Affected patients are characterized by kinky hair, hypotonia, and generalized myoclonic seizures. Here, we report a case of Menkes disease in which the patient presented with progressive hypotonia and intractable seizures. A 4-month-old male infant visited our pediatric clinic for focal seizures with blinking eyes. He was generally hypotonic and suffered from malnutrition. The focal seizures became more frequent, and the patient became intractable to anti-seizure medications. An electroencephalogram (EEG) indicated diffuse cerebral dysfunction with focal seizure, and a brain magnetic resonance imaging (MRI) showed tortuous and ectatic intracranial arteries, as well as several ischemic lesions. A genetic analysis was performed, and a c.2473_2474del (p.Leu825fsX1) of the ATP7A gene was detected.
