Injury of diaphragm mainly occur in penetrating, crush and blunt injuries to the lower chest or upper abdomen, and it is most often secondary to automobile accidents. Diaphragmatic rupture is most frequent in blunt chest trauma and the rate is below 1% of them. Traumatic rupture of the diaphragm is responsible for the herniation of abdominal viscera. Physical finding and radiographic sign of diaphragmatic hernia is nonspecific and misreading. Therefore, the diagnosis of traumatic rupture of diaphragm may be difficult during the early period after the injury, especially when clinical features are dominated by associated injuries. Emergency surgical management is necessary when it is complicated with serious complication. We experienced the case of traumatic diaphragmatic hernia detected after the operation of femur fracture. The patient was injured by motor vehicle accident 6 days before the operation of the femur fracture. There was no specific symptom and sign and the manifestation of the diaphragmatic hernia. in radiographic studies until operation of the femur fracture was done. Diaphragmatic hernia was confirmed by chest X-ray and arterial blood gas analysis after operation of the femur fracture. The repair of the diaphragmatic hernia was directly performed after the diagnosis. The prognosis was favorable, and she was discharged to ward from intensive care unit after 1 day of operation. We must consider the possibility of traumatic diaphragmatic hernia in the patient who have the history of blunt chest or abdominal trauma.

One of the goals of anesthesia is complete, comfortable and rapid recovery without sequelae from anesthesia. We compared the recovery pattern between anesthesia with propofol and thiopental/isoflurane. The fifty patients undergoing emergency appendectomy were allocated randomly to receive one of the anesthesia with propofol or thiopental/isoflurane. All of the patients were also given fentanyl, atracurium in equivocal dosage per weight and 50% N2O. Group 1(patient No; 25) was received anesthesia with fentanyl, atracurium, N2O and continuous injection of 6~12 mg/kg/hour of propofol. Group 2(patient No; 25) was received anesthesia with thiopental, fentanyl, atracurium, N2O and 1~2 MAC(minimal alveolar concentration) of isoflurane. We studied the duration of return of self respiration from discontinuation of anesthetics and recovery pattern in time sequence. The results were as following; The group 1 compared with group 2 at early recovery phase. 1) The duration of return of self respiration from discontinuation of anesthetics retured more rapid. 2) Emergence time was more rapid. 3) Postoperative sequelae(nausea, vomiting, sedation, drowsiness, memory dysfunction, pain) rate was less severe. But at recovery phase after 24 hours, there were no significant difference in postoperative sequelae and recovery condition in both groups. Therefore, we concluded that propofol is better than thiopental/isoflurane for anesthesia of emergency appendectomy in view of early recovery pattern.

Golgi SNAP receptor complex 1 (GS28) has been implicated in vesicular transport between intra-Golgi networks and between endoplasmic reticulum (ER) and Golgi. Additional role(s) of GS28 within cells have not been well characterized. We observed decreased expression of GS28 in rat ischemic hippocampus. In this study, we examined the role of GS28 and its molecular mechanisms in neuronal (SK-N-SH) cell death induced by hydrogen peroxide (H2O2). GS28 siRNA-transfected cells treated with H2O2 showed a significant increase in cytotoxicity under glutathione (GSH)-depleted conditions after pretreatment with buthionine sulfoximine, which corresponded to an increase of intracellular reactive oxygen species (ROS) in the cells. Pretreatment of GS28 siRNA-transfected cells with p38 chemical inhibitor significantly inhibited cytotoxicity; we also observed that p38 was activated in the cells by immunoblot analysis. We confirmed the role of p38 MAPK in cotransfected cells with GS28 siRNA and p38 siRNA in the cell viability assay, flow cytometry, and immunoblot. Involvement of apoptotic or autophagic processes in the cells was not shown in the cell viability, flow cytometry, and immunoblot analyses. However, pretreatment of the cells with necrostatin-1 completely inhibited H2O2-induced cytotoxicity, ROS generation, and p38 activation, indicating that the cell death is necroptotic. Collectively these data imply that H2O2 induces necroptotic cell death in the GS28 siRNA-transfected cells and that the necroptotic signals are mediated by sequential activations in RIP1/p38/ROS. Taken together, these results indicate that GS28 has a protective role in H2O2-induced necroptosis via inhibition of p38 MAPK in GSH-depleted neuronal cells.

BACKGROUND/AIMS: The aim of this study was to evaluate the effect of alpha-interferon (IFN) on liver histology as well as on activation of hepatic stellate cell ( HSC) and trans for ming growth fact or beta-1 (TGF beta-1) expression. We had also investigated the clinical usefulness of TGFbeta-1 and alpha-smooth muscle actin (alpha-SMA) expression in liver tissue for predicting a response to alpha-IFN therapy in chronic hepat it is B. METHODS: We studied the expression of TGFbeta-1 and alpha-SMA in liver biopsys pecimens from 51 chronic hepatitis B pat ients. Using immunohistochemical staining and a semiquant it ative scoring met hod, we also evaluated TGF-beta1 and alpha-SMA expression in liver stellate cells before and after alpha-IFN therapy in liver tissue from rebiopsys pecimen of the 12 chronic hepatitis B pat ients. Recombinant IFN alpha-2b (Intron A) in doses of 6 MU/ d was given to patients intramus cularly three times per week for 6 months (total doses , 432 MU). The patients were divided into two groups according to serum alanine aminotransferase levels as well as HBV- DNA and HBeAg s eroconversion stat e. Histological grading and staging scores were according to modified Histological Activity Index (HAI) grading systems of Ishak (1995). RESULTS: The index of portal inflammation and total scores of HAI grading significantly decreased in biopsies after alpha-IFN treatment, but the scores of fibrosis staging showed no significant change in biopsies after IFN treatment. A significant decrease in alpha-SMA expression, especially in periportal area, was found, but the change of TGFbeta-1 expression was not significant. The immunoreactivity of alpha-SMA was significantly lower in responders than in non-responders, whereas the diffference of immunoreactivity of TGF-beta1 between these two groups was not found. CONCLUSIONS: These findings suggest that alpha-IFN therapy may reduce the necroinflammatory activity in liver tissues of chronic B viral hepatitis and that the degree of alpha-SMA expression before treatment may be employed as a pottent predicting indicator for the therapeutic efficacy of IFN-alpha.

Extradural spinal meningiomas are uncommon, and their pathophysiology is not entirely understood. Here, we present the case of a 49-year-old woman with low back and left leg pain of 5 years duration. Magnetic resonance imaging revealed a mass, 1.8-cm in size, with rim enhancement in the spinal canal at the T12 level and extending into the left T12-L1 foramen. In the surgical field, the mass presented with the characteristics of an extra-intradural spinal meningioma. The patient underwent a T12 total laminectomy. A linear durotomy was performed at the midline, and the intradural portion was removed. The extradural portion was not separable from the adjacent dura and the left T12 root, and it was removed by dural excision. Pathological examination confirmed the diagnosis of psammomatous meningioma. We also conducted a literature review of similar cases. Based on our experience with this case, we believe that it is important to clearly distinguish extradural meningiomas from other types of tumors as misdiagnosis can change the operative plan. The long term prognosis of extradural meningiomas is not clear but total excision is thought to be essential.

PURPOSE: To report the clinical features, clinical course, and treatment outcomes after laser photocoagulation in infants with aggressive posterior retinopathy of prematurity (APROP) and capillary-free zones in vascularized retina. METHODS: Six patients (12 eyes) with APROP and capillary-free zones in vascularized retina were retrospectively reviewed. Twelve eyes of six infants were included and were treated with laser photocoagulation for avascular retina and for capillary-free zones in vascularized retina, except for the posterior pole, and fundus findings were photographically-documented in sequence. In addition, anatomic and visual outcomes were evaluated with complications of APROP. RESULTS: Among all of the consecutive infants with APROP, capillary-free zones in vascularized retina were demonstrated in 24% of the infants. All of the infants were >27 weeks of gestation age and had birth weights >1,000 g. After laser treatment, 7 eyes (58.3%) had favorable outcomes, and late capillary filling in capillary-free zones of vascularized retina were noted, however 4 eyes (33.3%) progressed to retinal detachment and 1 eye (8.3%) was complicated by a retinal fold-distorting posterior pole. The visual outcomes were associated with anatomic outcomes. CONCLUSIONS: The anatomic outcomes in infants with APROP who had capillary-free zones were comparable to previously reported infants with APROP. The late capillary filling of capillary-free zones in vascularized retina was noted, and angiogenesis was considered to be involved. This process toward normal capillary formation or neovascularization in APROP, might determine its outcome.

A 39-year-old man, his 35-year-old wife, and their 13-year-old daughter were found dead in their home. The man and his daughter were found lying in her bedroom, with his head wrapped in a plastic bag connected to four helium gas cylinders by green polypropylene tubes. Fragments of the burnt ignition briquette were found in the bucket located at her feet. His wife was found in a decomposed state lying on her right side in her bedroom. Autopsy findings for the man were unremarkable except for cherry pink lividity; the blood carboxyhemoglobin concentration was 73%. Autopsy findings were unremarkable for the woman as well, except for a few petechial hemorrhages and conjunctival congestion. The daughter showed no definite abnormalities; however, her blood and lung contained helium gas. The deceased man's suicide note, evidence gathered at the scene, and postmortem examination revealed that this was a case of dyadic death.

PURPOSE: To assess the long-term anatomic and visual outcomes and associated complications of lens-sparing vitrectomy (LSV) in infants with progressive posterior-type tractional retinal detachment (TRD) associated with stage 4A retinopathy of prematurity (ROP). METHODS: In a retrospective case series, the medical records of consecutive patients who presented with progressive posterior-type stage 4A ROP and underwent LSV between 1999 and 2007 were reviewed. Retinal attachment status, visual acuity, and development of postoperative complications were assessed. RESULTS: Eleven eyes of 9 patients were included. The mean follow-up period was 4.6 years. In 8 eyes (73%), plus disease was present at the time of LSV. In 3 eyes (27%), 2 (66%) without plus disease and 1 (13%) with plus disease, the retina remained reattached in the end, while 8 eyes (73%) had TRD on final examination. Two eyes with reattached retinas showed favorable visual acuity. In those eyes with detached retinas, 5 (68%) showed no light perception. When surgery for ROP was unsuccessful, development of cataract, corneal opacity, or glaucoma was common. CONCLUSIONS: The long-term anatomic success rate of LSV for progressive posterior-type stage 4A ROP was low, especially in the presence of plus disease at the time of LSV. Anatomical reattachment is very important for preventing complications and gaining better visual outcomes.
