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.

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.

PURPOSE: To determine the effects of intravitreal anti-vascular endothelial growth factor (VEGF) on thickness of the retinal nerve fiber layer (RNFL) in patients with age-related macular degeneration. METHODS: Twenty eyes of 20 patients diagnosed with age-related macular degeneration who underwent intravitreal anti-VEGF injection were studied. Postinjection RNFL thickness was measured using optical coherence tomography. Average thickness, four-quadrant RNFL thicknesses, and intraocular pressure (IOP) in affected eyes were measured before and 6 and 12 months after anti-VEGF injection for comparison. RNFL thickness and IOP in affected and normal fellow eyes were also compared. Given that macular lesions can affect RNFL thickness, the changes in thickness were evaluated by dividing the 12 clock-hour RNFL into the pathologic areas adjacent to the lesion and the non-pathologic area. RESULTS: The mean clock-hour segment in the pathologic area was 4.8 hours. A significantly thicker RNFL was exhibited in temporal quadrants and pathologic areas (p = 0.043 and 0.048, respectively) in affected eyes before injection compared to the baseline RNFL thickness in normal eyes. No significant differences were found in RNFL thickness or IOP between affected and normal eyes after injection. The changes over time in the temporal and pathologic areas were statistically significant at 6 and 12 months after injection compared to baseline data (p < 0.05). No significant differences were displayed in RNFL thickness in the other three quadrants or in non-pathologic areas in either affected or normal eyes. Sequential changes in RNFL thickness in affected eyes were not significant. CONCLUSIONS: Repeat intravitreal anti-VEGF treatment did not have a significant effect on RNFL thickness. RNFL thickness significantly decreased with time in the pathologic areas and in the temporal segment adjacent to exudative macular lesions. The reduction in RNFL thickness was most likely associated with changes in the macular lesion rather than with anti-VEGF injection.

PURPOSE: N-acetylcysteine (NAC) has been known to have protective effects on the prevention of radiocontrast induced nephropathy (RCIN) in chronic renal failure (CRF). We investigated the effects of NAC in acute renal failure (ARF). METHODS: From January to June 2006, we retrospectively enrolled patients with ARF who were checked with contrast computed tomography (CT) at an emergency department. We divided patients into the NAC group and the control group. We compared baseline demographic characteristics, underlying diseases, infused fluid volume, blood urea nitrogen (BUN), and serum creatinine (Cr) level before and after CT scan. ARF was defined as serum Cr>1.5. mg/dL. RCIN was defined as an increase in serum Cr level of at least 0.5 mg/dL or 25% 48 hours after CT. RESULTS: Of a total 106 cases, 23 patients were the NAC group and 83 were the control group. There were no significant differences in baseline findings including underlying disease, cause of ARF and serum Cr level. The volume of infused fluid before and after CT were not different between the two groups (before; p=0.183 after; p=0.149). After CT scan, BUN and serum Cr level were decreased without statistical significance in both groups (NAC vs control group: BUN; 21.0+/-12.9 vs 20.5+/-14.2 p=0.863 Cr; 1.3+/-0.5 vs 1.4+/-0.5 p=0.451). RCIN developed in total 3 cases, 2 cases in the NAC group and 1 in the control group (p=0.524) and one of the NAC group performed hemodialysis. CONCLUSION: In case of patients with ARF, there was no protective effect of NAC on RCIN.

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.

PURPOSE: To report a case of Pseudomonas aeruginosa infection after scleral buckling for retinal detachment. CASE SUMMARY: A 68-year-old male presented with a 2-day history of pain in the right eye. The patient had a history of scleral buckling for retinal detachment 10 years earlier and excisional biopsy for conjunctival mass 1 month previously. Biopsy revealed chronic inflammation and granulation tissue formation. Slit-lamp examinations revealed superior conjunctival injection, edema and exposed suture knot. Fundus examination revealed exudative retinal detachment and choroidal detachment. The conjunctival lesion did not improve although the patient was treated with moxifloxacin. After 4 days, bacterial and fungal cultures were performed because the conjunctiva presented with purulent discharge 4 days after treatment. The scleral buckle and suture knot were removed. The cultures revealed growth of Pseudomonas aeruginosa. According to antibiotic sensitivity test results, the authors treated the patient with ceftazidime. The conjunctival lesion, choroidal detachment and exudative retinal detachment were improved. CONCLUSIONS: In patients with conjunctival injection, edema, purulent discharge and ocular pain after scleral buckling, presence of infection should be suspected. If scleral buckle infection is suspected, bacterial culture, antibiotics treatment and scleral buckle removal should be considered.
