There have been many debates concerning operative decompression of treatment of thoracolumbar burst fractures with retropulsed bone fragment. From March 1988 to February 1992, authors treated thirty-three thoracolumbar burst fractures by using transpedicular screw fixation and posterior fusion via the posterior approach. We attempted to reduce retropulsed fragment by ligamentotaxis alone and not to do posterolateral nor anterior decompression. After the reduction of fractured spine by posterior instrumentation, we tried to determine the efficiency of reduction of the retropulsed fragment by ligamentaxis along. As a method, we compared the change of anteroposterior, transverse to diameter and area of spinal canal of fractured spine between preoperative and the postoperative situation. The results were as follows; 1. The mean anteroposterior and transverse diameter of the spinal canal on computed tomogram film was 10.1mm & 21.8mm preoperatively & 12.4mm & 23.2mm postoperatively, showing an increase. 2. The area of spinal canal of involved spine on CT film was evaluated preoperatively & post-operatively, the mean spinal canal invasion rate decreased from 36.3% preoperatively to 14.3% postoperatively. 3. The degree of reduction of middle height on plain x-ray and reduction of spinal canal invasion on computed tomogram were statistically correlated(p < 0.01). 4. There was no correlation between the degree of canal narrowing and degree of neurologic impairment. also, there was no correlation between the reduction of retropulsed fragments and subsequent neurologic impairment. 5. There was the relatively satisfactory enlargement of the spinal canal on computed tomogram at the follow-up So we suggest that it is possible to get enough decompression through reduction of retropulsed fragment by ligamen to taxis alone without posterolateral decompression.

Submucosal infiltration and the topical application of epinephrine as a vasoconstrictor produce excellent hemostasis during surgery. The hemodynamic effects of epinephrine have been documented in numerous studies. However, its metabolic effects (especially during surgery) have been seldom recognized clinically. We report two cases of significant metabolic effects (including lactic acidosis and hyperglycemia) as well as hemodynamic effects in healthy patients undergoing orthognathic surgery with general anesthesia. Epinephrine can induce glycolysis and pyruvate generation, which result in lactic acidosis, via β2-adrenergic receptors. Therefore, careful perioperative observation for changes in plasma lactate and glucose levels along with intensive monitoring of vital signs should be carried out when epinephrine is excessively used as a vasoconstrictor during surgery.

Increasing evidence suggests an association between elevated serum aminotransferase level and the metabolic syndrome. However, the significance of relatively low levels of aminotransferase in relation to the metabolic syndrome has not been fully investigated in the general population. We investigated the association between serum amiontransferase level and the metabolic syndrome using data from a nationwide survey in Korea. We measured serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels and metabolic conditions among 9771 participants aged 20 or more in the 1998 and 2001 Korean National Health and Nutrition Examination Surveys. Metabolic syndrome was defined according to NCEP-ATP III criteria with a modified waist circumference cutoff (men > 90cm; women > 80cm). Serum aminotransferase level, even within normal range, was associated with the metabolic syndrome independent of age, body mass index, waist circumference, smoking, and alcohol intake. Compared with the lowest level (<20IU/L), the adjusted odds ratios (95% CI) for an AST level of 20-29, 30-39, 40-49 and > or = 50IU/L were 1.10 (0.85-1.42), 1.37 (1.02-1.83), 1.62 (1.08-2.43), and 2.25 (1.47-3.44) in men, and 1.18 (0.99-1.41), 1.43 (1.29-1.83), 1.71 (1.09-2.68), and 2.14 (1.20-3.80) in women, respectively. Corresponding odds ratios for ALT levels were 1.27 (0.99-1.63), 1.69 (1.28-2.23), 2.17 (1.58-2.99), and 2.65 (1.96-3.58) in men, and 1.44 (1.22-1.70), 1.65 (1.26-2.15), 2.94 (1.93-4.47), and 2.25 (1.54-3.30) in women, respectively. In conclusion, elevated serum aminotransferase levels, even in the normal to near normal range, are associated with features of the metabolic syndrome.

BACKGROUND: This study evaluated echocardiographic changes in full-term healthy neonates during early transitional period from postnatal 0–72 hours at 12-hour intervals by echocardiography. METHODS: This was a prospective, observational, and longitudinal single-center cohort study. Morphometric, functional, systolic, diastolic, and tissue Doppler imaging (TDI) parameters (patent ductus arteriosus [PDA], aorta, superior vena cava [SVC], stroke volume [SV], cardiac output [CO], cardiac index [CI], early diastolic flow velocity [E], late diastolic flow velocity [A], early filling in TDI [E′], peak systolic annular velocity in TDI [S′], late velocity peak in TDI [A′], and myocardial performance index [MPI]) were evaluated in left ventricle (LV) and right ventricle (RV) with 56 newborns. RESULTS: Sizes and peak velocities of PDA before postnatal 24 hours were significantly changed than those after postnatal 24 hours. Aortic velocity time integral (VTI), systolic blood pressure (BP), LV SV/kg, LV CO/kg, LV CI, and SVC flow/LV CO before 24 hours showed significantly changes than those after 24 hours. Also, LV and RV MPI before 24 hours were significantly higher than those after 24 hours. LV E/E′ was significantly higher than RV E/E′. CONCLUSION: Postnatal 24 hours is critical time for hemodynamic closure of PDA because aortic VTI, systolic BP, LV SV, LV CO, LV CI, and SVC flow/LV CO showed simultaneously significant changes after 24 hours at the same time as 24 hours of physiological closure of PDA. Chronological and dramatic changes of systolic, diastolic, and TDI parameters during early postnatal period can be used to compile normal baseline data of healthy full-term neonates.

OBJECTIVE: The objective of this study was to determine whether complications and nursing interventions during hemodialysis could be reduced by using gradient ultrafiltration(GUF) and high sodium dialysate(HSD). METHODS: Thirty outpatients who had been on hemodialysis for more than 3 months were enrolled. Patients received Conventional HD(Na+ 137 mEqX4 hrs, constant UF), GUF(UF 62.5%X2 hrs, UF 37.5 %X2 hrs), HSD(Na+ 145 mEqX2 hrs, Na+ 140 mEqX2 hrs) and HSUF(GUF and HSD). Each methods were prescribed for 2 weeks. The clinical features such as thirst, interdialytic weight gain, postdialytic weight loss and MAP(mean arterial pressure) and the frequency of intradialytic complications and nursing interventions were evaluated. RESULTS: The results were as followings. Interdialytic thirst, weight gain, postdialytic weight loss and MAP(pre/post HD) were not significantly different in each method. On the other hand, there was significant difference between 4 methods in serum sodium, osmolality and Hct. There were significantly fewer episodes of hypotention, muscle cramp and headache when using GUF, HSD and HSUF than CHD. The number of nursing interventions was significantly reduced in GUF, HSD and HSUF than CHD. CONCLUSION: Hemodialysis with gradient ultrafiltration and high sodium dialysate leads fewer complications and nursing interventions, more patient's well being.

A thorough disinfection and infection control process associated with gastrointestinal endoscopy is highly important for the health and safety of the examinee and the medical staff involved in the procedure. Endoscopic reprocessing and disinfection are two of the most important steps in quality control of endoscopy. In 2019, the Korean Society of Gastrointestinal Endoscopy updated the Accreditation of Qualified Endoscopy Unit assessment items for these quality indicators. Assessment of disinfection and infection control comprises 28 mandatory items in the categories of disinfection education, pre-cleaning, cleaning, disinfection, rinsing, drying, reprocessing, storage, endoscopic accessories, water bottle and connectors, space/facilities, personal protective equipment, disinfection ledger, and regulations regarding infection control and disinfection. The updated Accreditation of Qualified Endoscopy Unit assessment items are useful for improving the quality of endoscopy by ensuring thorough inspection of endoscopic disinfection and infection control.

We report a case in which routine chest roentgenograms of an 840 g infant led to the belief that the peripherally inserted central catheter (PICC) was appropriately positioned within the superior vena cava when, in actuality, it was within the azygous arch. Although many cases of pleural effusions have been reported to be caused by a central venous catheter, a right-sided hydrothorax caused by azygous vein rupture from the use of a PICC is an extremely rare complication. Sudden changes in the condition of a preterm infant with PICC should raise the suspicion of a catheter- related problem.

We reported two cases of diabetic hyperglycemic hyperosmolar coma treated with maintaining continuous ambulatory peritoneal dialysis(CAPD) in chronic renal failure(CRF) patients with CAPD. Hyperglycemia is common complication in CAPD, but there were only few reports of severe hyperglycemia accompanying with hyperosmolar coma in CRF patients on CAPD therapy. Furthermore, to date, no specific management for CAPD patients with nonketotic hyperosmolar coma has been established. The best strategy for management of hyperosmolar coma with CAPD patients is changing CAPD therapy to HD. Recently, we experienced two cases of hyperglycemic hyperosmolar coma in diabetic CAPD patients successfully treated with intravenous hydration and insulin therapy without discontinuing CAPD therapy. Because no such case has been reported, we report two cases of diabetic hyperosmolar coma with CAPD treated without conversion to HD. These cases suggest that adequate fluid replacement accompanying electrolytes and osmotic balance as well as insulin therapy might be a major role for safe treatment of hyperglycemic hyperosmolar coma in patient with CAPD.
