PURPOSE: To report a case of corneal edema caused by an iatrogenic lidocaine injection into the corneal stroma created while performing a local anesthetic (lidocaine) injection into the eyelid for a blepharoplasty procedure. CASE SUMMARY: A 15-year-old female visited our clinic after the onset of severe pain and decreased visual acuity while receiving a local anesthetic injection in the upper blepharon for a blepharoplasty procedure. At the first clinical visit, visual acuity was hand motion and an accurate anterior chamber examination was difficult because of corneal edema. The Seidel test was negative. On corneal optical coherence tomography, the corneal thickness was 1,580 µm without any sign of Descemet's membrane detachment. We prescribed 5% NaCl four times a day and prednisolone acetate eight times a day. On the next day after injury, the corneal edema was significantly improved (central corneal thickness: 660 µm), and Descemet's membrane detachment was still not observed. One week after injury, the naïve visual acuity was 20/20, the central corneal thickness was 560 µm, and the endothelial cell count was 3,260 cells/cm². Three weeks after injury, the corneal edema was fully resolved and only slight temporal corneal haziness remained. After 2 months, the cornea was clear without any subjective discomfort. CONCLUSIONS: Corneal edema without Descemet's membrane detachment can be resolved spontaneously without aggressive treatment such as gas or air injection. However, endothelial cell count and corneal opacity need to be monitored on follow up exam. This clinical experience suggests that severe corneal edema in anterior stromal layer could be spontaneously resolved without severe complication.

By means of hospital-based data over 8 years we sought to evaluate the clinical indications and incidence of emergency peripartum hysterectomy by demographic characteristic and reproduction history. From the obstetric record of all deliveries at Chung Goo Hospital between Jan. 1, 1990, and Nov. 31, 1997, we identified all women undergoing emergency cesarean hysterectomy, calculated incidence rates, conducted statistical tests of linear trends and heterogenety, and observed the clinical indicatons preceding the onset of this procedure. There were 16731 deliveries during this period, Cesarean hysterectomy was performed in 24 of 5993 cesarean sections(0.40%) and in 10 of 10738 vaginal deleveries(0.09%), so more frequently after cesarean section than vaginal delivery. The age of patients varied from 22 to 40 years old. The higher the age and the parity of patients, the higher incidence of cesarean hysterectomy was noted. The most common indication of cesarean hysterectomy was uterine atony(52.94%) followed by placental disorders(41.18%), uterine myoma with pregnancy(2.9%) and uterine rupture (2.9%). All patients who had hysterectomy received transfusion from 1 pint to 57 pints. The postoperative complications were bladder injury, febrile morbidity, disseminated intravascular coaguolopathy and wound disruption. There were three maternal deaths, the cause was disseminated intravascular coaguolopathy and amniotic embolism. The data identifiy uterine atony as the primary cause for gravid hysterctomy. The data also illustrated how the incidence of emergency peripartum hysterectomy increases significantly with increasing parity, especially when influenced by a current placenta previa or a prior cesarean section. Maternal morbidity remained high.

Purpose:
Children have few small alveoli, which reduce lung compliance; in contrast, their cartilaginous rib cage makes their chest wall highly compliant. This combination promotes lung collapse. Prolonged inspiratory to expiratory (I:E) ratio ventilation is used to optimize gas exchange and respiratory mechanics in surgery. However, the optimal ratio is unclear in children. We hypothesized that, compared to a 1:2 I:E ratio, a 1:1 I:E ratio would improve dynamic compliance and oxygenation, and affect the peak airway pressure in pediatric patients undergoing surgery.
Materials and Methods:
Forty-eight patients aged ≤6 years who were scheduled to undergo surgery under general anesthesia with an arterial line were randomly allocated to receive 1:1 (group 1:1) or 1:2 (group 1:2) I:E ratio ventilation. Airway pressure, respiratory system compliance, and arterial blood gas analyses were compared between groups immediately after induction (T0), 30 min after induction (T1), 60 min after induction (T2), immediately after surgery (T3), and on arrival at the post-anesthesia care unit (T4).
Results:
Peak and plateau airway pressures were significantly lower in group 1:1 than in group 1:2 at T1 (p=0.044 and 0.048, respectively). The dynamic and static compliances were significantly higher in group 1:1 than in group 1:2 at T1 (p=0.044 and 0.045, respectively). However, the partial pressure of oxygen did not significantly differ between groups.
Conclusion
Compared to a 1:2 I:E ratio, a 1:1 I:E ratio improved dynamic compliance and lowered the peak airway pressure without complications in pediatric patients. Nevertheless, our results do not support its use solely for improving oxygenation.

The incidence of ectopic pregnancy is a marked increase in both the absolute number and rate in recent years. But dramatic decrease in death from ectopic pregnancies probably due to improved diagnosis and management. The aim of the study was to investigate the effect of intramuscular Methotrexate(MTX) injection on the treatment of ectopic pregnancy. The method of the study was made by the retrospective clinical observations on the 32 cases of unruptured ectopic pregnancies in Chung Goo Sung Sim hospital, department of Obstetrics & Gynecology. The results were as follows: 1) The most frequent age group was 25-29 year group(37.5%). 2) Nullipara was 31.3% and the case who experienced artificial abortion was 75%. 3) A previous history of abdominal or pelvic surgery was in 40.6% and pelvic inflammatory in 6.3%. 4) The mean ectopic gestational week was 6.4 weeks, 5) On symptomatological analysis, lower abdominal pain was encounted 53.1%, vaginal spotting was 40.6%. 6) The resolution of patients was obtained in 29 cases(90.6%)of 32 unruptured tubal pregnancies with intramuscular methotrexate treatment. 7) The mean resolution duration was 23.8 days. 8) The side effects of methotrexate were observed in 10 cases(31.2%)of 32 unruptured tubal pregnancies, but the severity of symptoms was mild. Consequently, tveatment by intramuscular injection of MTX expects to be one of the therapies alternating to surgery. However success rate remained 90.6% with and toxicity rate 31.2% with MTX injection. Therefore patients selection criteria and MTX dosage adjustment are more stricdy required for rising success rate and avoidance of toxic complication.

OBJECTIVES: The purpose of this study was to find the protective effects of garlic on the halogenated hydrocarbon induced hepatotoxicities, and the possible protection mechanisms involved. METHODS: Male Sprague-Dawley rats received garlic (0.5 %) or regular diet, for 4 weeks. This was followed by a single dose of corn oil (the controls), carbon tetrachloride (400mg/kg body weight) and trichloroethylene (2,000mg/kg body weight) being administered to each diet group. Blood samples were collected 24 hours following the administration, and the serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities measured. The liver samples were studied for their cytochrome P450 and CYP2E1 contents, lipid peroxidation and histopathology. RESULTS: The results for the group receiving the 0.5 % garlic diet showed a slight decrease of CYP2E1 expression compared with the regular diet group. Carbon tetrachloride was significantly decreased the CYP2E1 contents in both the regular and garlic diet groups, but the trichloroethylene remained unchanged. Garlic did not decrease the lipid peroxidation of the liver in the control group, but attenuated the increase of lipid peroxidation caused by carbon tetrachloride. Garlic attenuated the increase of both the serum AST and ALT activities caused by carbon tetrachloride. The histopathological observations also showed that garlic attenuated centrilobular necrosis and vacuolar degenerative changes significantly in the carbon tetrachloride treated group. Conclusions : The results indicate that garlic attenuates the carbon tetrachloride-induced hepatotoxicity, through the prevention of the metabolic activation and lipid peroxidation.
