1.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.

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.

Polyethylene glycols (PEGs) are believed to be chemically inert agents, but larger PEG polymers could have immunogenicity. A 39-year-old man was referred to emergency room for loss of consciousness and dyspnea after taking of PEG-3350 (Colyte®). In laboratory findings, the initial serum tryptase level was increased to 91.9 mg/L (normal range: 0.00-11.40 mg/L) without any other laboratory abnormalities. The intradermal test with 10 mg/mL Colyte® showed a 5 × 5 mm wheal, but basophil activation and histamine releasability tests were negative. PEG-3350 is widely used as an osmotic laxative due to its lack of absorption from the gastrointestinal tract. However, the loss of mucosal integrity at gastrointestinal membrane such as diverticulitis may be a predisposing factor for anaphylaxis to Colyte®. We report a case of anaphylaxis induced by the ingestion of PEG-3350 in a patient with diverticulitis which might be a risk factor of anaphylaxis.

PURPOSE: The aim of this study was to determine the reliability and validity of the Visual Analogue Scale (VAS), as a pain measurement tool in children and adolescents who visit the Pediatric Emergency Department (PED). METHODS: This was a prospective, descriptive study, using convenience sampling, of all children between the ages of 5 and 16 years who presented to a PED. The children were excluded who did not cooperate, who altered mentality or sensorium, who were clinically unstable or required admission to the intensive care unit, or who were developmentally delayed. Children were asked to mark their pain severity on the standardized 100-mm VAS, being instructed to slide the marker to the point on the scale that best described their pain. They were also asked to describe their pain as "none", "mild", "moderate", "severe", or "worst". RESULTS: A total of 716 children and adolescents were enrolled with a mean age of 9.7+/-3.6 years. Males accounted for 439(61.3%). In the children and adolescent who rated their pain as none, (n=10), the mean score was 3.9 mm (95% CI = 0.7 to 7.1); for mild (n=292), the mean score was 30.1 mm (95% CI=28.8 to 31.5); and for moderate pain (n=209) the mean score was 52.4 mm (95% CI=51.2 to 53.6). For those with severe pain (n=187), the mean score was 75.0 mm (95% CI=73.5 to 76.5), and for those who considered their pain the worst (n=18), the mean score was 94.7 mm (95% CI=90.0 to 99.5) (p=0.000). There was no significant relationship between VAS and sex, injury mechanism, or location of pain (p=0.387, p=0.233, p=0.144). The VAS was higher in patients who visited at night on ordinary days (p=0.022) and who were diagnosed with a fracture (71.1+/-20.0 mm) or headache (60.5+/-21.0 mm) (p=0.000). The value was also higher in patients who needed admission (64.9+/-21.5 mm) and an operation (70.7+/-23.0 mm) (p=0.000, p=0.000). CONCLUSION: This study demonstrates the quantification via the VAS of pain severity in children and adolescents who visit to the PED. This scale can be used as a tool for triage, pain management, and deriving a prognosis in the PED.

Wiskott-Aldrich syndrome(WAS) is an X-linked recessive immunodeficiency characterized by thrombocytopenia with small platelet volume, eczema, and recurrent infections, and is also characterized by increased incidence of auto immune diseases and malignancies. The phenotype observed in this syndrome is caused by mutation in the Wiskott-Aldrich syndrome protein(WASP) gene localized to the proximal short arm of the X chromosome and recently isolated through positional cloning. The gene encodes a 502 amino acid protein, which contains 12 exons and spans 9 kb of genomic DNA. The function of the encoded protein is not well understood. The clinical diagnosis of WAS can be difficult and is usually confirmed by the detection of WASP gene mutations and the expression of WSAP in patient blood sample using genetic analysis. We reported a case of a 13-month old boy with WAS who was identified with the novel mutation in exon 2 of WASP gene by direct sequencing and the complete absence of WASP expression by immunoblotting.

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.

PURPOSE: We wanted to evaluate the patella height, the tibial inclination and the joint height changes after closing-wedge high tibial osteotomy (CW HTO) and opening-wedge high tibial osteotomy (OW HTO). MATERIALS AND METHODS: The lateral radiographs taken with 30degrees flexion of the knees for 46 CW HTOs and 32 OW HTOs were assessed regarding the patellar height by the Insall-Salvati index (ISI) and the Blackburne-Peel index (BPI) and for the tibial inclination by the Moore-Harvey (MH) method. The average follow up period was 3.6 years (range: 2.0 to 4.7 years). Spearman correlation analysis was used to determine the influence of the two types of HTO with the amount of correction in the frontal plane Hip-Knee-Ankle (H-K-A) axis. The joint height was measured between the fibular head and the lateral tibial plateau. Measurements were made at the preoperative, postoperative and final follow-up periods. RESULTS: In the CW group, both the ISI and BPI were increased at the postoperative and final follow-up periods, while the BPI showed a statistically significant increase (p=0.046). In the OW group, both the ISI and BPI were decreased, while the BPI showed a statistically significant decrease (p=0.007). There was a tendency of a decrease of the tibial inclination in the CW HTO group without statistical significance. But in the OW HTO group, there was a statistically significant increase of the tibial inclination (p=0.012). The frontal plane H-K-A axis correction did not influence the change of the patellar height and tibial inclination in both groups (r<0.3). The joint height measured between the fibular tip and the lateral tibial plateau showed a significant decrease in the CW group (p=0.000), while there was no significant change in the OW group. CONCLUSION: The anatomical alteration of the patellar height was significantly influenced in opposite ways by the two methods of HTO. The BPI was more statistically significant then the ISI for the measurement of the patellar height after HTO. The joint height was significantly decreased in the CW HTO group. These changes should be kept in mind when converting HTO to total knee arthroplasty.

It is extremely rare to observe ossifying lipoma that developes separately from bone tissues in the groin. A patient with an adult fist-sized, firm, non-movable and painless mass in the left groin area, had been treated with marginal excision, which turned out to be ossifying lipoma. Although many different variants of lipoma with bone tissue have been reported, a case like this has never previously been reported. It is important to distinguish ossifying lipoma, from tumors with calcific lesions. We report its uniqueness in radiologic and pathologic ways, with specific findings of ossifying lipoma.

Apolipoprotein (apo) E deficient mouse can produce reproducible fixed stenotic primary atherosclerotic lesion, which reveals failure to remodel of vascular lumen, in the ascending aorta, external carotid, common carotid, iliac, femoral and popliteal arteries. To evaluate the effect of drugs in regarding to both prevention of primary atherosclerotic lesion and vascular remodeling, a systematic analysis of distribution of atherosclerotic lesions was undertaken in chow-fed, 9-momth-old apo E deficient mice, which was administrated drugs including asprin, methotrexate, probucol, sulodexide, diltiazem, cilazapril, trimetazidine, molsidomine, pentoxiphylline and Ginexin (R) for 7 month from 3 month-old. On gross and microscopic examination, formation of primary atheroscleotic lesions could be delated and/or prevented patially by effets of these drugs. On morphometric examination, failure to remodel forming vascular stenosis could not be seen, though relatively mild atherosclerotic lesion occured at vascular tree. These data suggest that the stenotic process in advanced atherosclerotic vessels can be delayed and/or prevented by several drugs including methotrexate, probucol, sulodexide, diltiazem, cilazapril, trimetazidine, molsidomine, pentoxiphylline and Ginexin (R) in vivo state.

BACKGROUND/AIMS: The treatment for steroid-refractory acute graft versus host disease (GVHD) after allogeneic stem cell transplantation (allo-SCT) needs to be standardized. We report our clinical experience with etanercept for steroid-refractory acute GVHD. METHODS: Eighteen patients who underwent allo-SCT and presented with steroid-refractory acute GVHD at Ajou University Hospital were studied retrospectively. They were given 25 mg of etanercept subcutaneously twice weekly for 4 weeks. The clinical responses were evaluated with regard to the severity of acute GVHD. RESULTS: The median patient age was 43.5 years. Using nonparametric tests, etanercept had a down-grading effect on acute GVHD (p = 0.005), although no patient experienced complete remission. Partial responses were seen in 80%, 17%, and 57% of grade II to IV patients, respectively. Skin and gut GVHD were well controlled with etanercept, whereas hepatic GVHD was not. Four patients died of fatal infections. No factors affecting the clinical outcome of etanercept were identified. CONCLUSIONS: Etanercept has a modest effect on steroid-refractory acute GVHD after allo-SCT, with tolerable side effects.
