Continuous renal replacement therapy (CRRT) has been used in critically ill children for more than 20 years in the world, but in Korea, although it is becoming the preferred method of acute therapy in pediatric intensive care units, there has been a few experiences and no consensus of CRRT up to now. This review describes the basic technique of CRRT, highlights the between the adult and pediatric prescription, and elaborates on the main controversies in the application of CRRT in children.

There are still some controversies regarding one stage repair of pectus deformity with congenital heart disease due to probable complications after extensive resection of deformed cartilages. We performed Nuss operation with simul-taneous intracardiac repair in 8 year old patient with pectus excavatum and partial atrioventricular septal defect. The result of operation was satisfactory without prolongation of operation time, bleeding or instability of chest wall.

Diabetic polyneuropathy (DPN) is the most common form of diabetic neuropathy, and causes a significant morbidity with an impact on the quality of life in the patients with diabetes. Since DPN frequently induces foot deformity and ulceration, which finally leads to foot amputation, the early detection and treatment is very important for the prevention of a permanent structural change. In the early stage of DPN, the diagnostic methods which can evaluate the function or structure of small nerve fibers should be employed because small nerve fibers are first involved in the course of DPN. However, the nerve conduction study cannot reflect the function of the small nerve fibers, and thus, has a definite limitation in the early diagnosis of DPN. For the early detection of DPN, electrodiagnostic data should be interpreted on a clinical context, along with the careful evaluation of the small nerve fiber functions using the tests such as the analysis of intraepidermal nerve fiber density.

Diabetic polyneuropathy (DPN) is the most frequently encountered form of neuropathy in diabetic patients, and it either relentlessly progresses or remains relatively stable for many years, not showing any trend towards improvement. From this point of view, early detection of DPN is very important to prevent the irreversible change of the peripheral nerve from diabetic insults. Although a number of clinical symptoms and/or deficit scales have been developed for clinical or research purposes, nerve conduction study (NCS) has been known one of the most objective and sensitive tools to detect peripheral nerve dysfunctions in diabetic patients. NCS, however, also have several shortcomings. The next two consecutive articles will focus on debates about diagnostic usefulness of NCS and on recent updates of other diagnostic tests including quantitative sensory testings and skin biopsy in the field of diabetic polyneuropathy.

It was not until the early twentieth century that statistics emerged as an independent academic discipline. The developments of statistical theory and methods would not have been possible without heated controversies among founding fathers. One of them, controversy on the statistical test between R. A. Fisher and J. Neyman, E. S. Pearson had been very fierce and long-lasting. On the other hand it was in the early twentieth century that psychologists began to utilize statistical test which was a hybrid of tests developed by Fisher and Neyman-Pearson. By considering the history of fields such as psychology, we can see distinctive characteristics specific to the history of statistics.

Urinary tract infection (UTI), the most common bacterial disease in childhood, is frequently associated with urinary tract anomalies (15-50%) and can induce renal scarring, which is a cause of hypertension and chronic kidney disease. Despite the high risk of renal scarring in infancy, the diagnosis may be delayed due to its nonspecific presenting symptoms; moreover, over-diagnosis is frequent due to the contamination of urine samples. The delay in diagnosis and treatment may induce sepsis or renal scar, while over-diagnosis is responsible for unnecessary antibiotic treatment and costly urinary imaging studies. UTI guidelines have been ever-changing for the past three decades, but some controversial issues remain. This article is a revision of the previous KSPN (Korean Society of Pediatric Nephrology) guideline and addresses the recent controversies concerning childhood UTI.

In numerous studios of Technology Acceptance Model ( TAM ), the social Influence construct has been operationalized as subjective norm. This study Proposes to stretch two construct to Include two more constructs : image and visibility. This paper also questions about the paths regarding this comprehensive construct. Due to the controversies regarding the significance of social Influence on IS usage, this study taps the possibility that social influence works as an antecedent to PU (Perceived Usefulness) and PEU ( Perceived Ease of Use) We could find the significant differences In path coefficients depending on how social Influence Is operationalzied.

There are many controversies in managing fresh substance tear of PCL. Conservative treatment of partial tear is generalby accepted idea, and less than 10mm posterior instability is known to be acceptable in terms of funtion. More than 10mm posterior instability and complete fresh tear of the ligament are regarded as candidates of reconstruction of the ligament. However, many authors believe that posterior instability may be a cause of early osteoarthritis in the long run. Author described the rationale and the technique of arthroscopic primary repair of the PCL in case of proximal and mid 1/3 substance tear. Postoperative rehabilitation program and their rationale were also described.

Herpes zoster in childhood is uncommon, but it is more common in association with immunosuppression. Maternal varicella infection during pregnancy and varicella occurring in the newborn represent risk for childhood herpes zoster. However, some controversies persist on risk factors, diagnosis, and the natural history of childhood disease. We report a 10-year-old healthy boy with shingles and review the risk factors, prognosis, and treatment of pediatric zoster.

The mitral valve is not a simple but a complex structure, mitral valve complex. This complex is composed of mitral orifice, annulus, valve leaflet, chordae tendineae and papillary muscles. There were many controversies about this structures. We studied mitral valve complex in 63 cases of normal Korean adults, such as the circumference of mitral annulus, the intercommissural diameter, height and breadth of the cusps, including commissure, the ratio of rough to clear zone, breadth of the achordal zone, the number of scallops of posterior cusp, the number, length and the pattern of arrangement of the several types of chordae, the number and morphological characteristics of papillary muscles.
