Purpose: This study evaluated the clinical and radiological outcomes of TFNA (Trochanteric Fixation NailAdvanced; Depuy Synthes) for the treatment of proximal femur fractures. Materials and Methods: This was a retrospective study of 64 patients diagnosed with a proximal femur fracture from January 2019 to November 2019. The patient’s demographic data, preoperatively and postoperatively Koval grade, modified Harris hip score, EQ-5D (Euro-Qol-5 Dimension), sliding and advancement of the blade, radiologic outcome, and complications were investigated. Results: Fifty patients were available for evaluation at one year postoperatively. The patients reported the following: the Koval grade decreased after surgery; the modified Harris hip score decreased from 78.56±8.88 to 72.74±6.59 (p=0.149); the mean EQ-5D decreased from 0.75±0.09 to 0.72±0.06 (p=0.000). Satisfactory reduction was achieved on a postoperative radiographic examination in 47 patients in six months. Complications occurred in seven cases. Conclusion TFNA is considered an appropriate implant for treating intertrochanteric fractures of the femur with a minimum follow-up of one year.

PURPOSE: This study was designed to evaluate the characteristics of exertional heat stroke between the non-survival and the survival groups. METHODS: From January 1996 to December 2002, patients with exertional heat stroke who came to the emergency department of a military hospital were enrolled. Data on individual factors, atmospheric conditions, pre-hospital management, initial vital signs, laboratory findings, presence of seizure attack, and performance of intubation were reviewed retrospectively and compared between the nonsurvival and the survival groups. RESULTS: During the study period, 22 patients were diagnosed as suffering from exertional heat stroke and 5 patients died. Most of the episodes occurred during the summer days with high ambient temperature (mean 30.6+/-3.0 degrees C) and humidity (mean 75.6+/-7.7%), and 13 patients were unacclimatized recruits. The non-survival group showed a lower initial systolic blood pressure, platelet count, arterial pH, and HCO3 - level, and a higher serum creatinine, ALT, and amylase level than did the survival group (p<0.05). However there were no significant differences in individual factors, atmospheric conditions, pre-hospital management, initial pulse rate, temperature, white blood cell count, hemoglobin count, and the sodium, potassium, BUN and AST levels between the two groups. CONCLUSION: Initial systolic blood pressure, platelet count, and arterial pH, as well as HCO3 -, serum creatinine, ALT, and amylase levels seem to be important factors for the prognosis of exertional heat stroke.

PURPOSE: This study was designed to prove the efficacy of neutralization with weak acid against strong alkali ingestion and to evaluate exothermic reaction of neutralization therapy. METHODS: 30 New Zealand White rabbits were anesthetized with intravenous injection of ketamine and xylazine. After gastric lavage was done, a orogastric catheter and a electric thermometer probe were inserted into stomach. And then the rabbits were divided into six groups. The first group was given 3M NaOH 16.5 mL only. The second and third groups were given 3M NaOH 16.5 mL and then 1M C H3COOH 52.14 mL one and three minutes later, respectively. The fourth and fifth groups were given tap water instead of CH3COOH, and the sixth group was given C H3COOH only. We monitored intragastric temperature continuously, compared arterial pHs before alkali infusion and 15 minutes later, measured gastric pH 15 minutes later, and examined pathologic findings of stomach after sacrificing. RESULTS: There was no significant thermal effect in all groups, and gastric pH of neutralization groups was much lower than alkali alone or dilution groups. Changes of arterial pH after 15 minutes were greater in alkali alone and dilution groups than neutralization groups. In gross and microscopic findings of stomach, only mucosal injuries were observed in neutralization groups, especially in one minute group. But all stomach layers were destroyed in alkali alone and dilution groups. CONCLUSION: Neutralization therapy never makes additional thermal injury, and has protective effects against local tissue destruction and systemic alkalemia. Dilution therapy shows little or no effects.

PURPOSE: To investigate the accuracy and reproducibility of Optical Low Coherence Reflectometry (OLCR) corneal thickness measurements compared with the Orbscan system and ultrasound pachymeter (IOPac, Mentor). METHODS: Two examiners measured corneal thicknesses of 78 normal eyes and in 36 eyes that had undergone LASIK, and five sequential measurements of corneal thickness with OLCR, Orbscan system, Mentor, and IOPac were performed. Remeasurements of corneal thickness in 24 normal eyes were performed after two days to investigate intra-examiner reproducibility. RESULTS: The average corneal thickness measured in normal subjects was 536.3+/-23.8 micrometer in OLCR, 542.4+/-25.3 micrometer in the Orbscan system, 535.4+/-23.7 micrometer in Mentor, and 534.2+/-24.1 micrometer in IOPac. The average corneal thickness measured in patients who had undergone LASIK was 487.3+/-30.8 micrometer in OLCR, 492.5+/-36.5 micrometer in the Orbscan system, 487.5+/-30.8 micrometer in Mentor, and 485.3+/-30.8 micrometer in IOPac. There was no statistically significant difference between the four pachymeters. The inter-examiner and intra-examiner reproducibilities were shown to be highly reliable. CONCLUSIONS: The OLCR showed similar measurments of corneal thickness with the Orbscan system and ultrasound pachymeter, and showed no difference in reproducibility with different examiners.

PURPOSE: Proteomics is a peptide screening approach to identify proteins related to physiological and pathological changes. Our objective was to analyze changes in serum proteome profiles in patients suffering from septic shock, during the first 24-h period of therapy and to determine whether these changes were associated with prognosis. METHODS: This was a retrospective observational study based on prospectively collected data that was conducted in an emergency intensive care unit (ICU) of a tertiary referral hospital. Consecutive patients admitted to the ICU with septic shock were enrolled. We obtained serum samples from the patients at admission (0 h) and 24 h after admission (24 h). Then, we analyzed the serum proteome profiles, performed Western blots, and measured serum lipid profiles. RESULTS: Twenty-seven patients were enrolled. Thirteen patients were grouped into the survivors (SURV) group and fourteen into the non-survivors group on day 30 (NON-SURV). Proteomic analyses and Western blot showed that the expression intensities of proapolipoprotein AI remained unchanged in SURV but decreased in NON-SURV during the first 24-h period of septic shock (p=0.015). Serum high density lipoprotein (HDL) cholesterol level also remained unchanged in SURV but decreased in NON-SURV (p=0.036). CONCLUSION: The decrease in serum proapolipoprotein AI expression during the first 24-h period of therapy was associated with a consistently low serum HDL cholesterol level and a poor prognosis in patients with septic shock.

PURPOSE: To report the clinical characteristics of patients with opacification of intraocular lens (IOL) after cataract surgery with hydrophilic acrylic IOL. METHODS: Retrospective evaluation was performed for 102 eyes of 74 patients who had undergone cataract extraction, with insertion of hydrophilic acrylic IOL (ACRL-C160). The medical records of 91 eyes of 69 patients who were followed up for more than 6 months were reviewed retrospectively. The clinical characteristics of the patients with IOL opacification were analyzed, and the characteristics were compared between the groups of patients with and without IOL opacification. RESULTS: In 70 eyes of 52 patients IOL opacification developed. The incidence was 19.8% at 6 months, 52.3% at 1 year, and 84.1% at 2 years after cataract surgery. The onset of IOL opacification ranged from 2 to 25 months (11.1 months on average). The incidence of IOL opacification was not affected by systemic disease such as diabetes mellitus and hypertension. In the group of patients with IOL opacification, the onset of IOL opacification occured earlier than in the patient group with diabetes mellitus and it also developed earlier in patients with longer duration of diabetes mellitus and diabetic retinopathy. IOL opacification was more severe in patients with retinopathy than in those without diabetic retinopathy. CONCLUSIONS: The incidence of hydrophilic acrylic IOL opacification increased over time and had risen to 84.1% of cases at 2 years after surgery. Although patients with generalized disease were not associated with the development of IOL opacification, the presence of diabetes mellitus and diabetic retinopathy affected the onset and severity of IOL opacification.

Transcatheter arterial embolization (TAE) is widely used in the treatment of unresectable hepatocellular carcinoma. Its common complications are right upper quadrant pain, nausea, vomiting, and rare complications include focal pancreatic necrosis, gastric ulcer, renal failure, DIC, biliary tree necrosis and splenic infarction and so on. It has been reported that hepatobronchial fistula could develop as a pleuropulmonary complication of liver abscess. We report a case of hepatobronchial fistula caused by complicating liver abscess in a patient with hepatocellular carcinoma who was treated with TAE.

OBJECTIVE: Stenotrophomonas maltophilia has been emerging as an important nosocomial pathogen in recent years in patients with impaired host- defense mechanism or who has been exposed to large amount of inocula. This organism is usually resistant to multiple (commonly used) antimicrobial agents, particularly to those of the beta-lactam class. To evaluate the clinical feature of Stenotrophomonas maltophilia infection and in vitro anti- microbial susceptibility, we performed a retrospective study. METHODS: We analyzed the result of in vitro antimicrobial susceptibility test for 200 isolates of S. maltophilia and the annual isolation rate during the period between January 1990 and December 1994 in our institution, and performed a retrospective study for the available records of 165 cases among them. The data were obtained with only the first isolation of the organism for each patients. RESULTS: Total of 165 initial isolates, the isolates were from wounds in 50(30.3%), urine in 47(28.5%), the respiratory tract in 37(22.4%), blood in 9(5.5%), bile in 6(3.6%), and miscellaneous sources in 16(9.7%). The 84.2% of isolates were hospital-acquired isolate and 58.3% of these patients had received antecedent antibiotic therapy: polymicrobial growth was demonstrated in 61.9% of the cases. In vitro antimicrobial susceptibiiity test, ofloxacin was active against the isolates in 89.2%, moxalactam in 85.9%, ciprofloxacin in 83.9%, TMP-SMX(trimethoprim-sulfamethoxazole) in 64.2%, As expected, S. maltophilia isolates were, in general, not susceptible to cephalosporins, penicillins. The annual isolation rate at Kyung Hee University hospital was not increased significantly from 1990 to 1994, 19.53 per 10,000 patients dismissals in 1990, 13.56 in 1994. The major underlying diseases of patients were malignancy(17.6%), cerebrovascular disorder(17%), diabetic mellitus(13.3%). Mortality rate is 10.3%. CONCLUSION: S. maltophilia has been emerging as an important nosocomial pathogen in immunocompromised patients, especially those receiving broad-spectrum antimicrobial therapy. And this organism is resistant to multiple antimicrobial agents, particularly to those of the beta-lactam class. When antimicrobial treatment is necessary, the clinician should be guided by results of in vitro susceptibility testing because of the notable in vitro resistance of S. maltophilia to commonly used antibiotics. And when S. maltophilia has been recovered from a patient, wound and contact isolation is warranted.

OBJECTIVES: Organophosphates make their clinical effects after absorbed through gastrointestinal tract, lungs and skin. We commonly see the gastrointestinal tract and lung as routes of organophosphates (OP) intoxication, but there have been few reports that said the skin as a route OP intoxication. We have experienced many patients that showed OP intoxication symptoms during or after the control of pine gall midge. So we analyzed the clinical characteristics of the patients and evaluated the route of OP intoxication. METHODS: We analyzed retrospectively 26 cases who were diagnosed as 'OP intoxication after control of pine gall midge' from June 1 1995 to July 31 1996. RESULTS: 1) The mean age of the cases, mean duration of work and mean initial cholinesterase level were 52 years, 11.9 days, 318.2U/L respectively. And the over all ratio of male to female was 11:15. 2) All cases were engaged in drug injection and 7 cases (32%) weared mask. Face and upper body were excluded from protective clothings. 3) The cardinal symptoms were diarrhea and dizziness followed by nausea, vomiting, headache, anorexia, paralysis in order of frequency. 4 Directly contributing factors to symptom onset were rain, excessive sweating due to hot weather and direct contact. 5) Most of cases (92%) were recovered completely. 2 cases died during hospitalization due to acute respiratory failure and sepsis. Mechanical ventilation were applied in 4 cases for mean 12 days. In 2 cases, there were neurobehavioral changes as delayed neurologic sequelae. CONCLUSION: We have concluded that the route of organophosporus intoxication after the control of pine gall midge was skin (transdermal absorption). Sufficient education and protective measures should be done for preventing organophosporus intoxication in the control of pine gall midge.
