Blood Pressure Reference Values for Normal Weight Korean Children and Adolescents: Data from The Korea National Health and Nutrition Examination Survey 1998–2016: The Korean Working Group of Pediatric Hypertension

BACKGROUND AND OBJECTIVES@#Hypertension is becoming one of the most common health conditions in children and adolescents due to increasing childhood obesity. We aimed to provide the auscultatory blood pressure (BP) normative reference values for Korean non-overweight children and adolescents.@*METHODS@#BP measurements in children and adolescents aged 10 to 18 years were performed in the Korean National Health and Nutrition Examination Survey (KNHANES) from 1998 to 2016. BP was measured using a mercury sphygmomanometer. Sex-, age- and height-specific systolic BP (SBP) and diastolic BP (DBP) percentiles were calculated in the non-overweight children (n=10,442). We used the General Additive Model for Location Scale and Shape method to calculate BP percentiles.@*RESULTS@#The 50th, 90th, 95th, and 99th percentiles of SBP and DBP tables and graphs of non-overweight children and adolescents aged 10 to 18 years were presented by age and height percentiles. We found that the SBP and DBP at the 95th percentile were well correlated with height. The BP tables presented by height contained BP values from 124 cm to 190 cm for boys and from 120 cm to 178 cm for girls. Boys had higher SBP and DBP.@*CONCLUSIONS@#We provided the sex-, age- and height-specific auscultatory BP values using the KNHANES big data. These may be useful in diagnosis and treatment of hypertension in Korean children and adolescents.

Massive hemothorax immediately after removal of central venous catheter: A case report / 대한마취과학회지

Hemothorax is a possible immediate complication of central venous catheterization. We experienced a patient who suffered from massive hemothorax 72 hours after right subclavian venous catheterization. A 29-year-old female patient with Marfan's syndrome underwent the Bentall's operation and aortic arch replacement with an artificial graft, which was performed uneventfully. She recovered favorably in the intensive care unit and was transferred to the general ward on postoperative day 3. Immediately after the removal of the catheter in the general ward, massive hemothorax developed and emergent thoracotomy should have been performed to control bleeding. We report this case to re-emphasize the careful monitoring even after removal of central venous catheter and the need for ultrasound guidance during insertion of central venous catheters.

Coexistence of Medullary and Papillary Thyroid Carcinoma / 대한내분비외과학회지

PURPOSE: The simultaneous occurrence of two distinct neoplasms derived from different cells of origin is a recognized entity. It presents uncommonly in all organs,and very rarely in the thyroid gland. METHODS: Six patients with concurrent medullary thyroid carcinoma (MTC) and papillary thyroid carcinoma (PTC) were seen between January 2000 and June 2007. Clinicopathological features were evaluated, and follow-up for the patients was obtained. RESULTS: All patients were female, with ages ranging from 39 to 63 years (mean age, 55.4 years). Five of six patients were incidentally detected during a medical check-up. The medullary carcinomas measured from 0.5 to 4.0 cm in diameter (mean diameter, 1.72 cm), while the papillary carcinomas ranged from 0.2 to 1.4 cm in diameter (mean diameter, 0.72 cm). Treatment consisted of a total thyroidectomy (n=5) and hemithyroidectomy (n=1) with central compartment node dissection. In twopatients, prophylactic bilateral neck dissection was also added. Supplemental radioactive iodine treatment was administered in five patients. During a mean follow-up period of 41.8 months, two patients showed recurrence in the lateral neck nodes, one recurrence from a papillary carcinoma and the other recurrence from a medullary carcinoma. After re-operation for the recurrent lesions, allof the patients were alive andfree of disease. CONCLUSION: Attention should be given to the possibility of the simultaneous occurrence of MTC and PTC. Treatment for concurrent MTC and PTC should be based on the treatment for MTC, considering the more aggressive behavior of the tumor than PTC.

Central Venous Obstruction in Hemodialysis Patients: The Usefulness of Percutaneous Treatment

PURPOSE: To analyse the effectiveness of percutaneous treatment of central venous obstruction in patients undergoing hemodialysis. MATERIALS AND METHODS: In 100 patients, 107 central venous strictures [56 subclavian (occlusion:21, stenosis:35) and 51 innominate (occlusion:23, stenosis:28)] were assessed, and 170 percutaneous angioplasty procedures were performed. Balloon dilation of the venous lumen was the preferred mode, but if dilation was incomplete we inserted a stent at the site of the stricture. Technical success, procedural complications and the long-term patency rate were evaluated, and the patency difference according to location and degree of stricture, the existence of DM, and any history of central catheter insertion were also determined. RESULTS: We inserted 52 stents in 170 procedures, in 157 (92.4%) of which initial technical success was achieved. Stent migration occurred in two cases and balloon rupture in three. The 6- and 12-month primary patency rates were 46.2% and 24.1%, respectively, and the mean patency rate was 8.5 months. The 1-, 2- and 3-year accumulative patency rates were 59.8%, 47.5% and 35.7%, respectively, and the mean patency rate was 23.5 months. Other than in the history of central catheter insertion, there were no statistically significant differences in patency rates (p=0.0128). CONCLUSION: In hemodialysis patients with a central venous stricture, percutaneous angioplasty is a safe and useful procedure, but to maintain long-term central venous patency, repeated interventions are required.

Venous Rupture Complicating Hemodialysis Access Angioplasty: Percutaneous Treatments and Outcomes

PURPOSE: To evaluate the usefulness of percutaneous management and prognosis in venous rupture during angioplasty of hemodialytic arteriovenous fistulas. MATERIALS AND METHODS: Among 814 patients who underwent angioplasty on account of inadequate hemodialysis, 63[39 women and 24 men aged 20-78 (mean, 55.8) years] were included in this study. All 63 had peripheral venous stenosis. Venous rupture was diagnosed when contrast leakage was seen at venography after percutaneous angioplasty (PTA). In order to manage venous rupture, the sites at which this occurred were compressed manually for 3-5 minutes or blood flow was blocked with a balloon catheter for the same period. In one case, a stent was inserted at the rupture site. Using the Kaplan-Meier method, we investigated the patency rate of arteriovenous fistula (AVF) in cases of successful PTA. We also compared PTA patency rates in cases with and without peripheral venous rupture. RESULTS: Venous rupture occurred in 38 cephalic, 16 brachial, and 9 basilic veins. In 63 patients, bleeding stopped and in 54 (85.7%) of these, PTA was successful. Among the nine failed cases, dilatation was incomplete in five, though bleeding had stopped. In patients with brachial and cephalic vein rupture, the venous tract at the rupture site was not located. Two patients underwent surgery: one of these experienced brachial venous rupture, with incontrollable bleeding, and the other had nerve compression symptoms due to hematoma. Among 54 patients in whom PTA was successful, the primary and secondary six-month rates for angioaccess were 47.9% and 81.2%, and the mean patency period was 6.1 and 15.8 months, respectively. In cases of non-venous rupture, the mean patency period was 9.6 months, significantly longer than in cases involving venous rupture (p=0.02). CONCLUSION: Venous rupture occurring during the PTA of hemodialytic AVF can be managed percutaneously.

A Case of Facial Nerve Palsy Associated with Epstein-Barr Virus Infection in a Child / 대한소아신경학회지

Facial palsy is a rare complication of infectious mononucleosis of Epstein-Barr virus infection, which can be easily overlooked by clinicians if one is unnoticed about it. We report a 2 year and 11 month old boy who was diagnosed by facial nerve palsy caused by Epstein-Barr virus infection. Pseudothrombocytopenia was also associated with him. Steroid (prednisolone 2mg/kg) was administered daily for 2 weeks and then maintained with alternative tapering schedule (2mg/kg at once QOD) in order to decompress facial nerve. He was completely recovered at 2 months of follow-up.

A Case of Isolated Adenomatous Polyp of Rectum in a Child: Tubulovillous adenoma / 대한소아소화기영양학회지

Isolated rectal adenomatous polyp without genetic background is rarely found in children. A 4-year and 5 month-old girl was admitted for intermittent bloody stools lasting 4 months. A 1.5x1.2 cm sized rectal polyp was found by air contrast barium enema. Endoscopic polypectomy was performed without complications. In histopathologic examination, it was found to be a tubulovillous adenoma. Typical radiologic, colonoscopic, and pathological pictures are presented.

Midgut Volvulus of Infant Simulating Intussusception Diagnosis with Color Doppler Ultrasonography / 대한소아소화기영양학회지

Although midgut volvulus is clinically characterized by bilous vomiting and abdominal distention, plain abdominal X-ray is usually non-specific and therefore it can be misdiagnosed to other diseases. Upper gastrointestinal contrast study and computed tomography have been used as a routine diagnostic tool but it takes cost and time. Abdominal ultrasonography is a relatively good alternatives in diagnosing midgut volvulus and it relatively saves cost and time. But case presentation of midgut volvulus diagnosed with abdominal ultrasonography are rarely found in literature. We experienced a 6 month old girl who had come to our hospital with bilous vomiting and was diagnosed as midgut volvulus with ultrasonography. Thus we report this case with the presentation of typical ultrasonographic findings of midgut volvulus.
