BACKGROUND: The aim of this study was to investigate the relationships between left ventricular ejection fraction (LVEF) and mortality and neurologic outcomes with post-cardiac arrest syndrome (PCAS) after out-of-hospital cardiac arrest (OHCA). METHODS: Patients with PCAS after OHCA admitted to the intensive care unit between January 2014 and December 2015 were analyzed retrospectively. RESULTS: total of 104 patients were enrolled in this study. The mean age was 54.4 ± 15.3 years, and 75 of the patients were male (72.1%). Arrest with a cardiac origin was found in 55 (52.9%). LVEF < 45%, 45-55%, and > 55% was measured in 39 (37.5%), 18 (17.3%), and 47 (45.2%) of patients, respectively. In multivariate analysis, severe LV dysfunction (LVEF < 45%) was significantly related to 7-day mortality (odds ratio 3.02, 95% Confidence Interval 1.01-9.0, p-value 0.047). CONCLUSIONS: In this study, moderate to severe LVEF within 48 hours after return of spontaneous circulation was significantly related to 7-day short-term mortality in patients with PCAS after OHCA. Clinicians should actively treat myocardial dysfunction, and further studies are needed.

3.Supraorbital Endoscopic Evacuation for Traumatic Intracerebral Hematomas in the Frontal Lobe
Journal of Korean Neurosurgical Society 2022;65(6):846-852
Objective:
: Traumatic intracranial hematomas have been rarely evacuated by endoscopic surgery. The frontal lobe is the usual location for the traumatic intracerebral hematoma (TICH). Endoscopic evacuation for the frontal TICHs via an eyebrow incision is to be presented as minimally invasive surgery.
Methods:
: Thirteen patients with frontal TICHs were managed with endoscopic hematoma evacuation via eyebrow incision. After making the incision in the lateral eyebrow, a small frontal craniotomy was made, and the hematoma was evacuated under direct visualization of a rigid endoscope. No catheter was placed. Orbital rim resection, hematoma evacuation rate, surgical complications, and outcome at discharge were analyzed.
Results:
: Men were 11 and the mean age was 54 years old (range, 27–86). Orbitotomy was performed in four patients, and no effect on the hematoma evacuation rate was observed. More than 80% of the hematoma volume was successfully removed in 10 cases. Hematoma configuration was not related to the hematoma evacuation rate. None of the patients underwent revision operation or decompressive craniectomy.
Conclusion
: Endoscopic evacuation of the TICHs with the supraorbital approach may be a good method to evacuate the hematoma located in the frontal base.

BACKGROUND: Pneumonia is the most common cause of death among patients with infectious disease in Korea. However, studies of pneumonia with septic shock in patients presenting to the emergency department are limited. The aim of this study was to investigate the prognostic factors associated with pneumonia with septic shock in patients presenting to the emergency department. METHODS: From January 2008 to September 2014, patients with pneumonia with septic shock admitted through the emergency department were retrospectively examined. RESULTS: Of the 561,845 patients who visited the emergency department, 398 were admitted for pneumonia with septic shock. The 28-day mortality rate in these patients was 36.4%. The independent prognostic factors were old age (>70 yrs) (odds ratio [OR], 2.42; 95%, confidence interval [CI], 1.35-4.32), Acute Physiology and Chronic Health Evaluation (APACHE) II score (OR, 1.04; 95% CI, 1.01-1.08), leukopenia (OR, 3.63; 95% CI, 1.48-8.94), prolonged PT-INR (OR, 2.53; 95% CI, 1.41-4.54), and hypoxemia (OR, 2.88; 95% CI, 1.30-6.38). CONCLUSIONS: A poor prognosis of patients with pneumonia is associated with old age (>70 yrs), increased APACHE II score, leukopenia, prolonged PT-INR, and hypoxemia.

5.Multiple langerhans cell histiocytosis at the lung and mandible: Case report.
Journal of the Korean Association of Oral and Maxillofacial Surgeons 2005;31(3):279-282
Hitiocytosis X, recently termed Langergans cell histiocytosis, is a rare disease histologically characterized by an abnormal proliferation of histiocytes, and of which the pathophysiology is still ambiguous. The clinical presentation is highly varied. Typically, there is a solitary or multiple bony involvements, and less frequently, lesions are found in other organs such as the lungs, liver, lymph nodes, skin, and mucosae. Interestingly, so far, there has been no report which shows multiple developments in both soft and hard tissues. In this report, we present a case of hitiocytosis X in both mandible and lung. This may provide some information for understanding the pathophysilogy of the histiocytosis X.

Journal of the Korean Ophthalmological Society 2003;44(6):1384-1391
PURPOSE: We present a case of acute zonal occult outer retinopathy (AZOOR) that has not been reported in Korea. METHODS: A 26-year-old female with photopsia and visual field defect in the left eye was referred to our hospital. There were no fundus abnormalities to explain the visual field defect. Electroretinography, indocyanine green angiography, neurologic examination, cerebrospinal fluid tapping and brain magnetic resonance imaging were performed for further evaluation. RESULTS: Visual acuity was 20/20 in both eyes. Visual field examination revealed a peripheral scotoma in the right eye and marked constriction of visual field in the left eye. Electroretinography showed normal response in the right eye and no response in the left eye. There was an afferent pupillary defect in the left eye and vitreous cells in both eyes. Indocyanine green angiography, neurologic examination, cerebrospinal fluid tapping and brain magnetic resonance imaging showed no abnormal findings. CONCLUSIONS: The possibility of AZOOR should be considered in a patient with photopsia, visual field defect, acute loss of outer retinal function confirmed with electroretinography, and minimal or no fundus and angiographic changes, especially in a young woman.

Traumatic optic neuropathy (TON) is an important cause of severe visual loss after blunt or penetrating head and facial trauma. High-dose steroids and surgical interventions have been applied in the indirect TON. However, there is no convincing evidence that results of the treatment have any strong benefits in terms of improvement of visual acuity. Nevertheless, surgical decompression should be considered in the case of a direct bony compression to the optic nerve and a progressive visual loss in indirect TON. Neurosurgeon should be aware the surgical indication, optimal timing and relevant technique for the optic canal (OC) decompression. In this review article, we will focus on the surgical approaches to the OC and how to decompress it.

Desmoplastic small round cell tumor (DSRCT) is a rare malignant mesenchymal neoplasm. It mainly involves the abdominal or pelvic peritoneum of male adolescents. We report here the imprint cytologic features of a case of DSRCT occurring in the intraabdominal cavity of a 21-year-old man. A microscopic examination showed moderate cellularity. The tumor cells were singly arranged and arranged in clusters. The cells had round to oval nuclei with finely granular chromatin, inconspicuous nucleoli and scanty cytoplasm. Some tumor cells showed nuclear molding, and some cells had an epitheloid appearance with a large amount of lightly eosinophilic cytoplasm. A rosette-like pattern was present. Spindle-shaped, fibroblastic stromal cells were occasionally found. The tumor cells were immunoreactive for the markers cytokeratin (AE1/AE3), epithelial membrane antigen (EMA), desmin, vimentin and neuron specific enolase (NSE).

OBJECTIVE: This study was performed to investigate the effects of metformin in PCOS patients undergoing IVF-ET. METHODS: From January 2002 to December 2004, 87 cycles in 32 PCOS patients undergoing IVF-ET at the Infertility clinic of Grace Women's Hospital were randomly divided into two groups and enrolled in this study. The diagnosis of PCOS was made by the criteria from 2003 Rotterdam Consensus. Metformin group (19 patients, 45 cycles) received metformin (Daewoong Pharma Co., Korea; 500 mg three times or two times a day from one or two months before and during IVF cycle) and control group (13 patients, 42 cycles) did not receive metformin. All patients received controlled ovarian hyperstimulation (COH) using gonadotropins (Fostimon, IBSA, Switzerland) with GnRH antagonist (Cetrotide, Serono, Germany). When leading follilces reached 18 mm in diameter, recombinant hCG 250 ?g (OVIDREL, Serono, Italy) was injected. Oocytes were retrieved transvaginally 35 hours later. The luteal phase was supported everyday by progesterone 50 mg IM (Progest, Samil, Korea) with micronized progesterone 200 mg vaginal insertion (Utrogestan, Besins, France). RESULTS: There was no statistical difference in the patients age (34.1+/-3.0 vs 33.5+/-2.9 years), the duration of infertility (4.3+/-1.3 vs 4.5.+/-1.3 years) and BMI (23.5+/-2.4 vs 24.01+/-2.7 kg/m2) among two groups (p> or =0.05 for each). There was also no statistical difference in the indications of IVF among two groups; ovulation factor (27 cycles vs 23 cycles), tubal factor (7 vs 8), male factor (8 vs 7) and other factor (3 vs 4) (p> or =0.05). The duration of ovulation induction in metformin group was significantly shorter when compared with control group (10.1+/-2.3 vs 13.8+/-2.2 days, p<0.05). Total doses of FSH-HP in metformin group were significantly less than that in control group (30.3+/-11.5 vs 39.9+/-11.7 ampules, p<0.05). There was no difference in the number of aspirated oocytes (10.5+/-4.7 vs 9.6+/-3.6), the fertilization rate (65.9+/-17.4% vs 63.2+/-25.9%), implantation rate (30.3+/-11.5% vs 38.1+/-17.3%) and the number of good quality embryo (5.0+/-1.8 vs 4.7+/-2.5, p< or =0.05). Clinical pregnancy rate was higher in metfomin group (33.3% vs. 23.8%), although statistically not significant. CONCLUSION: Although more randomized study is needed, metformin therapy in PCOS patients undergoing IVF has possibility of reducing the duration of COH and the gonadotropin doses.

OBJECTIVE: It was to analyze two failed arterial embolization cases in the treatment for pseudoaneurysm followed by D&C. METHODS: Two failure cases out of eight cases were gained in the transarterial embolization treatment for eight years.(1. 1. 1992 - 12. 31. 1999) To search for the factors of failure, we went through obstetrical history and biopsy. RESULTS: Eight cases of transarterial embolization were performed to the treatment for pseudoaneurysm appeared after undergoing D&C. Six cases were successfully treated without complications. However, laparotomy was done due to the continuous bleeding in the other two cases. According to tissue biopsy, they showed the cervical pregnancy in one case and placenta accreta in the other. CONCLUSION: Transarterial embolization is proved to be more preferable to operate in the treatment of pseudoaneurysm than laparotomy, and transarterial embolization therapy failure rate is higher in case of existing remnant villi than not.
