Objective : As a minimally invasive strategy, endoscopic technique was introduced for removal of the traumatic intracerebral hematoma. Material and Method : A 54-year-old man with three-day history of seizure and progressive mental deterioration after traffic accident was presented. Computerized Tomography(CT) of the brain showed a huge intracerebral hematoma on the right frontal lobe and ventricle. The operation was performed via right frontal superolateral keyhole with 2cm eyebrow skin incision. Using 0-degree and 30-degree angled lens 4mm rigid endoscopes, nearly all of the hematoma was evacuated under the direct endoscopic visualization and a ventricular catheter was exactly placed into the frontal horn of the right lateral ventricle at the end of procedure. Results : The seizure was discontinued and neurological status had been improved during postoperative periods. Postoperative CT demonstrated that most of the hematoma was removed and the ventricular drainge tube was exactly placed in the right foramen of Monro. Conclusion : With endoscopic technique, the authors successfully evacuated traumatic intracerebral hematoma and exactly placed the ventricular drainage catheter under direct visualization. This technique may be considered as an another option for removal of traumatic intracerebral hematoma.

Objective : The purpose of this study was to compare clinical and radiological outcomes of percutaneous endoscopic lumbar discectomy (PELD) and open lumbar microdiscectomy (OLM) for recurrent disc herniation. Methods : Fifty-four patients, who underwent surgery, either PELD (25 patients) or repeated OLM (29 patients), due to recurrent disc herniation at L4-5 level, were divided into two groups according to the surgical methods. Excluded were patients with sequestrated disc, calcified disc, severe neurological deficit, or instability. Clinical outcomes were assessed using Visual Analogue Scale (VAS) score and Oswestry Disability Index (ODI). Radiological variables were assessed using plain radiography and/or magnetic resonance imaging. Results : Mean operating time and hospital stay were significantly shorter in PELD group (45.8 minutes and 0.9 day, respectively) than OLM group (73.8 minutes and 3.8 days, respectively) (p < 0.001). Complications occurred in 4% in PELD group and 10.3% in OLM group in the perioperative period. At a mean follow-up duration of 34.2 months, the mean improvements of back pain, leg pain, and functional improvement were 4.0, 5.5, and 40.9% for PELD group and 2.3, 5.1, and 45.0% for OLM group, respectively. Second recurrence occurred in 4% after PELD and 10.3% after OLM. Disc height did not change after PELD, but significantly decreased after OLM (p = 0.0001). Neither sagittal rotation angle nor volume of multifidus muscle changed significantly in both groups. Conclusion : Both PELD and repeated OLM showed favorable outcomes for recurrent disc herniation, but PELD had advantages in terms of shorter operating time, hospital stay, and disc height preservation.

Objective : This study analyzed clinical and radiological outcomes of a zero-profile anchored spacer (Zero-P) and conventional cage-plate (CCP) for single level anterior cervical discectomy and fusion (ACDF) to compare the incidence and difference of postoperative dysphagia with both devices. Methods : We retrospectively reviewed our experiences of single level ACDF with the CCP and Zero-P. From January 2011 to December 2013, 48 patients who had single level herniated intervertebral disc were operated on using ACDF, with CCP in 27 patients and Zero-P in 21 patients. Patients who received more than double-level ACDF or combined circumferential fusion were excluded. Age, operation time, estimated blood loss (EBL), pre-operative modified Japanese Orthopaedic Association (mJOA) scores, post-operative mJOA scores, achieved mJOA scores and recovery rate of mJOA scores were assessed. Prevertebral soft tissue thickness and postoperative dysphagia were analyzed on the day of surgery, and 2 weeks and 6 months postoperatively. Results : The Zero-P group showed same or favorable clinical and radiological outcomes compared with the CCP group. Postoperative dysphagia was significantly low in the Zero-P group. Conclusions : Application of Zero-P may achieve favorable outcomes and reduce postoperative dysphagia in single level ACDF.

The current paper reports on a case of subdural empyema secondary to frontal sinusitis in an otherwise healthy child. Sinusitis is a common and benign condition in most pediatric cases. Because of the widespread use of antibiotics, intracranial extension of pediatric sinusitis is rarely seen today; however, complications (e.g., cavernous sinus thrombosis, orbital infection, meningitis, and subdural empyema) are potentially life threatening. A 15-year-old right-handed male presented with a 3-day history of fever, headache, and left-sided palsy. Computed tomography revealed right-sided subdural empyema with right frontal sinusitis and maxillary sinusitis. A postoperative inpatient neurological consultation was requested 2 months post-surgery due to motor function deficits. The results suggested that early and accurate diagnosis of subdural empyema leads to prompt treatment and a favorable outcome for the patient.

Parvovirus B19(PV B19) is a nonenveloped single-stranded DNA virus that causes a wide variety of diseases ranging from benign childhood infection such as slapped-cheek rash(fifth disease) to life threatening diseases such as hydrous fetalis in fetuses or aplastic anemic crises in patients with hemolytic anemia. In immunocompromised hosts including organ transplant recipients, this infection can cause chronic anemia. Recently, the reports of cases of PV B19 infection have been increasing in transplant recipients and most reported cases of PV B19 infection-associated anemia in renal transplant recipients were successfully treated with intravenous immunoglobulin infusion. We experienced two cases of aplastic anemia caused by PV B19 infection in pediatric renal transplant recipients. The patients were an 8 year-old boy and 12-year-old boy who received allograft kidneys from their mothers. Anemia developed 2 weeks after transplantation and their serum was positive for PV B19 PCR. They were treated with 400 mg/kg of intravenous immunoglobulin(IVIG) for 5 consecutive days. In one of the case, anemia was corrected promptly after the first 5-day course of IVIG therapy but in the other, anemia persisted but responded to the second course of IVIG therapy. One year later, the patients have normal hematocrit levels and stable renal function These are the first cases of PV B19 infection treated successfully with IVIG in pediatric renal transplant recipients in Korea.

In order to clarify the effect of the unilateral pneumonectomy on the compensatory growth of the residual lung, liver and kidney, and serum electrophoresis pattern, right lung pneumonectomy was performed on rabbits under general anesthesia with pentobarbital sodium. On the fifth day after the surgery, the weight of the residual lung, liver and bilateral kidneys was measured and organ weight-body weight ratio was calculated. And in an attempt to know whether the cells in the liver and the kidney were proliferated by unilateral pneumonectomy, DNA content was determined. The quantity(g/100 ml) of serum protein was determined also and serum electrophoresis was performed on cellulose acetate membrane. The results obtained are summarized as following. The weight of the residual lung and lung weight-body weight ratio was significantly increased respectively. The weight of the liver and organ weight-body weight ratio were not changed but the DNA content of the liver and kidney tissue increased significantly, illustrating that unilateral pneumonectomy caused cellular hyperplasia in the liver and in the kidney as well as in the residual lung. The quantity(g/100 ml) of serum protein was significantly increased and in the analysis of the electrophoregram, there was significant difference between the normal and pneumonectomy group. Taken together, these results indicate that unilateral pneumonectomy caused the compensatory hyperplasia of the liver, the kidney and the residual lung as well as the change of electro-phoretic pattern. And it also suggests that a humoral factor, which proliferates the cells in the residual lung, the liver and the kidney, existed in the pneumonectomized rabbits.

This report describes a case of dizziness in a patient with trigeminal neuralgia that was caused by a vestibular schwannoma. A 60-year-old man with a history of pain on his left cheek, chin, molar and tongue for 5 months was diagnosed as suffering with trigeminal neuralgia of the left mandibular nerve, and this was caused by a left vestibular schwannoma. The diagnosis of the tumor was confirmed with magnetic resonance imaging (MRI), and so gamma knife surgery was performed 1 month later. At that time, the patient had been referred to the pain clinic due to allodynia on the tongue and gingival, and hypesthesia was also present on the left half of the face. Trigeminal nerve block with dehydrogenated alcohol and stellate ganglion block with 1% mepivacaine were performed and oral medication with diphenylhydantoin was started. The symptoms were alleviated after nerve block and oral medication. Dizziness, blurred vision and ataxia then developed from the 13th hospital day. We considered the symptoms as a side effect of diphenylhydantoin and we reduced the dose of diphenylhydantoin. However, the symptoms grew worse. Another brain MRI showed a slight increase of the tumor size and a mass effect with displacement of the adjacent organs, and hydrocephalus was also noted. This case shows the importance of considering the secondary symptoms that are due to brain tumor while treating trigeminal neuralgia. The changes of the brain tumors should also be considered along with the presence of new side effects.

Wounds are commonly created during almost every kind of surgery, trauma and skin diseases. Delayed wound healing affects a plenty of patients and requires prolonged treatments that seriously reduce the quality of life for patients. Skin damage involving large areas or great severity can lead to disability or even death. Wound healing involves a complicated series of actions, of various tissues and cell lineages, concerning inflammation, migration, proliferation, reepithelialization, and remodeling. Sopung-san is reported to have anti-inflammatory effect and has been used for various skin diseases such as allergic dermatitis and atopic dermatitis. In this study, the hypothesis that oral treatment with Sopung-san could enhances healing potential on rat full thickness skin wounds was tested. Twenty young male Sprague-Dawley rats were used for the studies. A full-thickness skin wound was made on the dorsal skin of the rats. Either Sopung-san water extract (SPS) or saline (Control) was orally administrated every day. The wound area was measured and the percentages of wound contraction, wound healed and wound epithelization were calculated. Wound tissue samples were excised following injection for histopathological and immunohistological examination. Wound area in rats of SPS group significantly was decreased compared to Control. SPS group showed significant promotion of wound healing compared to Cotrol group in the percentages of wound contraction, wound healed and wound epithelization. Histopathological examination revealed that SPS induces neo-vascularization potential in wound healing process. SPS treatment in rats significantly accelerated cutaneous wound healing in the neo-vascularization process by increasing VEGF and $TGF-{\beta}1$ synthesis. The results suggest that Sopung-san affects key cellular processes responsible for wound repair and point to a unique potential for this molecule in the therapy of skin wounds, particularly as an angiogenic agent.

Plastibell is one of the three most common devices used for neonatal circumcision in the United States, with a complication rate as low as 1.8%. The Plastibell circumcision device is commonly used under local anesthesia for religious circumcision in male neonates, because of cosmetic reasons and ease of use. Occasionally, instead of falling off, the device may get buried under the skin along the shaft of the penis, thereby obstructing the normal flow of urine. Furthermore, the foreskin of neonates is highly vascularized, and hence, hemorrhage and infection are possible when the skin is cut. Necrosis of penile skin, followed by urethral obstruction and renal failure, is a serious surgical mishap requiring immediate corrective surgery and medical attention. We report a case of fulminant urosepsis, acute renal failure, and pyelonephritis in a 4-day-old male neonate secondary to impaction of a Plastibell circumcision device. Immediate medical management was initiated with fluid resuscitation and mechanical ventilation; thereby correcting life threatening complications. Pediatricians and Emergency Department physicians should be cognizant of the complications from Plastibell circumcision device in order to institute appropriate and timely management in neonates.

Percutaneous laser discectomy has potential advantages over conservative therapy and classical open surgery as a minimally invasive procedure, although clinical experiences are limited. We experienced a patient treated with herniated lumbar discs using Nd：YAG laser. A 55-year-old woman complained of severe back pain with sciatica on L4/5 and L5/S1 dermatome for several months. The MRI finding showed bulging discs at L4/5 and L5/S1. Epidural, transsacral and root block treatments were attempted without effect. Under fluoroscopic guidance, a 14 G biopsy needle was inserted into the L4/5 and L5/S1 disc spaces to the margin of the nucleus pulposus. Laser irradiation for vaporization of tissue was performed at 20 W/second to 1200 J. A laser fiber ($600{\mu}m$) was advanced 1 cm from the tip of the needle. At the end of the procedure, the patient began to feel relief of pain (VAS changed from 9 to 4) and was discharged the same day after staying 2 hours in the recovery room. Antibiotics were administered for prevention of discitis. She had no complaints of pain until the 1-month follow up visit. Percutaneous laser discetomy technique has the disadvantages of expensive equipment, high temperature and amount of vaporing disc tissue is empirical. However, this technique, as one of the therapeutic modalities for disc herniation, provides faster relief from acute attack than conservative management techniques in carefully selected patients with sciatica due to disc prolapse.
