To cover a large soft tissue defect of the finger, we have successfully applied free flaps using second dorsal metatarsal artery in 2 patients and obtained satisfactory results. It can be used to reconstruct the defect located from the proximal phalanx to the fingertip of all fingers as a new indication. The procedure is a time-saving, one stage operation. It also causes no disfigurement and no functional loss of the involved digit. Our clinical experience showed favorable results. Second dorsal metatarsal artery free flap is an alternative method to reconstruct a soft tissue defect of the finger with one-stage operation. This flap with its lengthy pedicle provides enough tissue padding. In the meantime, the vascular anatomy of the second dorsal metatarsal artery has to be investigated with regard to its general distribution and variation.

PURPOSE: Alloplastic implants, such as methylmethacrylate, Teflon, silicone, Supramid are commonly used to cover the floor defect and to prevent reherniation of the displaced orbital tissue in orbital floor fracture. Silicone implant has been used for reconstruction of orbital wall defects because of pliability, advantage of carving and chemically inert nature. However, silicone implant also has complications including infection, extrusion, pain, dystopia and tissue reaction. Cyst formation around the silicone implant is a very rare complication. According to many reports, cysts around alloplastic implant in an orbital area are mostly hemorrhagic cysts consisted of blood breakdown product with fibrous capsule cell in histologic examination. METHODS: The authors report atypical case and successful treatment of intraorbital hemorrhagic cyst around silicone implant of a 37-year-old male patient. RESULTS: Preoperative symptoms of diplopia, exophthalmos, proptosis, vertical dystopia and ectropion of lower eyelid were resolved after surgical removal of implants with surrounding capsule. CONCLUSION: Clinical suspicion of plastic surgeon is important in diagnosis of intraorbital cyst of patients who have history of silicone implantation and computed tomography is the standard tool of diagnosis. During the operation, caution must be taken on delivering the whole capsule of intraorbital cyst along with silicone implant to prevent recurrence of the cyst.

BACKGROUND: Nitrous oxide is a safe analgesics which has analgesic and sedative effects without loss of consciousness. The advantage of Nitrous oxide is that it has a rapid onset time and that we can modulate duration of its action. The purpose of this experiment is to obtain the safe and effective concentration of Nitrous oxide in Emergency Department as use of analgesics and sedative drugs. METHODS: Twenty volunteers were investigated according to double blind method. Nitrous oxide was administrated to volunteer subjects at different concentrations ; 33%, 50%, 67% each. Then we evaluated the Pain score, Blood pressure, Heart rate, Respiratory rate, Oxygen saturation and its side effects. RESULTS: Pain Score were 8.4+/-2.1 at 33%, 6.1+/-1.5 at 50%, and 3.65+/-2.2 at 67% of Nitrous oxide. Pain Score is decreased significantly following administration of Nitrous oxide at concentration of 50%, 67%(P<0.05). There was no difference between preadministration group and postadministration group. While no remarkable change in systolic blood pressure, heart rate, and oxygen saturation. Respiratory rate showed significant increase when 679o of Nitrous oxide was administrated. There was no side effect in administration of 33% of Nitrous oxide. When 50% of Nitrous oxide was administrated, there were dizziness 5(25%), paresthesia 2(10%), nausea 1(5%), palpitation 1(5%) and hyperethesia 1(5%). At 679o of Nitrous oxide, there were nausea 7(35%), dizziness 6(30%), paresthesia 5(25%), headache 5(25%), diplopia 2(10%), dysphoria 2(10%), salivation 1(5%), dyspnea 1(5%), nystagmus 1(5%), tinnitus 1(5%) and euphoria1 (5%). Incidence of side effect increased as the concentration of Nitrous oxide was increased. CONCLUSION: We can conclude that safe and effective concentration of Nitrous oxide is 50% as analgesics and sedative drugs in the emergency department.

Journal of Korean Neurosurgical Society 2021;64(6):957-965
Objective:
: Rapid increase in intracranial pressure (ICP) can result in hypertension, bradycardia and apnea, referred to as the Cushing phenomenon. During decompressive craniectomy (DC), rapid ICP decreases can cause changes in mean atrial blood pressure (mABP) and heart rate (HR), which may be an indicator of intact autoregulation and vasomotor reflex.
Methods:
: A total of 82 patients who underwent DC due to traumatic brain injury (42 cases), hypertensive intracerebral hematoma (19 cases), or major infarction (21 cases) were included in this prospective study. Simultaneous ICP, mABP, and HR changes were monitored in one minute intervals during, prior to and 5–10 minutes following the DC.
Results:
: After DC, the ICP decreased from 38.1±16.3 mmHg to 9.5±14.2 mmHg (p<0.001) and the mABP decreased from 86.4±14.5 mmHg to 72.5±11.4 mmHg (p<0.001). Conversly, overall HR was no significantly changed in HR, which was 100.1±19.7 rate/min prior to DC and 99.7±18.2 rate/min (p=0.848) after DC. Notably when the HR increased after DC, it correlated with a favorable outcome (p<0.001), however mortality was increased (p=0.032) when the HR decreased or remained unchanged.
Conclusion
: In this study, ICP was decreased in all patients after DC. Changes in HR were an indicator of preserved autoregulation and vasomotor reflex. The clinical outcome was improved in patients with increased HR after DC.

OBJECTIVE: To investigate the prevalence and risk factors of carpal tunnel syndrome in diabetic patients. METHOD: Electrodiagnostic study was performed to diagnose carpal tunnel syndrome and polyneuropathy in 266 (male 151, female 115) diabetic patients. General charateristics, diabetes related factors, anthropometric factors were compared between non-carpal tunnel syndrome and carpal tunnel syndrome groups to identify the risk factors for carpal tunnel syndrome. RESULTS: Prevalence of carpal tunnel syndrome in diabetic patients was 16.2 % (43 subjects). Female, farming, wrist depth width ratio (>or=0.7) were associated with carpal tunnel syndrome in diabetic patients. In right hand, odds ratio was 12.82 (95% confidence interval: 2.97~55.3) in female, 5.15 (95% confidence interval: 1.17~22.7) in farming, 28.53 (95% confidence interval: 1.80~451.1) in wrist depth width ratio (>or=0.7). The similar results were also observed in left hand. CONCLUSION: The results suggest that occupation, sex, and anthropometric factor like wrist shape were more associated with carpal tunnel syndrome in diabetic patients than diabetes mellitus itself.

Background:
The development of endovascular devices and clinical experience, recanalization rate after intraarterial thrombectomy (IA-Tx) has increased. Recent papers reported that the amount of perfusion/diffusion (P/D)-mismatching in digital analysis from computer tomography perfusion (CTP) image is well correlated well with P/D-mismatching from magnetic resonance image. The purpose of this study is compare the patient clinical outcomes after IA-Tx, judging from CTP based and magnetic resonance imaging (MRI) based study.
Methods:
: 218 patients with anterior circulation large vessel occlusion (LVO) treated by IA-Tx were included in this analysis. In the MRI group (n=80), P/D-mismatching from MRI based image analysis by visual method and in the CTP group (n=138), and recently, P/D-mismatching was decided by automatized computer programmatic analyzed from CTP based image (Syngo.via program).
Results:
Favorable outcome (modified Rankin Score: 0–2), mortality, recanalization, and clinically significant hemorrhage was 56.3% (45/80), 6.25% (5/80), 81.3% (65/80) and 25% (20/80) in MRI group and 4.9% (62/138), 8.9%(18/138), 91.3%(126/138) and 40.6% (56/138) in CTP group (p=0.000, 0.235, 0.007 and 0.013). Reperfusion injury (27.5% vs, 15.0%, p=0.018) but favorable outcome was high 55.0% vs. 44.9 $, p=0.00) in the MRI study group.
Conclusion
: In our study, patient selection according to the P/D-mismatching from MR-based imaging and CTP-based image was not different in final clinical outcome. Recent IA-Tx, showed high recanalization rate but it also cause high incidence of reperfusion injury.

PURPOSE: Autologous fat injection into the facial area is a frequently used technique in aesthetic plastic surgery for augmentation of the soft tissue. Fat injection is a very safe procedure because of the advantage of being autologous tissue. Minimal foreign body reaction or infections are noted after fat injection. However, there may be some complications including those as severe as blindness. There have been some case reports on visual disturbances after autologous fat injection reported in the literature. METHODS: A 21-year-old female patient underwent autologous fat injection into left eyebrow area to correct depression of soft tissue. Immediately after injection of autologous fat, she complained sudden visual loss on the left eye. She had come to our emergency room and ophthalmologic evaluation showed that the patient could only recognize hand motion. There was no abnormality of the optic nerve on magnetic resonance imaging. Suspecting an ischemic optic neuritis from fat embolism of the central retinal artery, the patient was treated conservatively with occular massage, antiglaucomatic agent, anti-inflammatory drugs and antibiotics. Visual field examination showed visual defect of half the lower hemisphere. RESULTS: While maintaining antiglaucomatic agents and non steroidal anti inflammatory drugs, fundoscopic examination showed no abnormalities on the second day of admission. Visual field examination showed an improvement on the fourth day along with decreased eyeball pain. Significant improvement of vision was noted and the patient was discharged on the fifth day of admission. The patient was followed-up 2 days afterwards with improved vision and visual field defect. CONCLUSION: We describe an unusual case of sudden unilateral visual disturbance following autologous fat injection into periorbital area.

BACKGROUND: Preoperative chemotherapy has been adopted in our hospital as a standard treatment for non-small cell lung cancer patients with N2 disease. However, there have been cases of pathologic N2 disease that have been detected after curative-intent surgical resection. We retrospectively studied the outcomes of initial surgical treatment without neoadjuvant therapy in patients with unexpected N2 non-small cell lung cancer. MATERIAL AND METHOD: Between January 1995 and June 2007, 225 patients were diagnosed with pathologic N2 disease after they underwent initial pulmonary resection without neoadjuvant therapy. Among them, 170 patients were preoperatively diagnosed with lymph node stage N0 or N1. We retrospectively reviewed their medical record and analyzed the outcomes. RESULT: The overall 5-year survival rate was 35.4%. The prognostic factors that were significantly associated with survival were no adjuvant therapy, histologic cell types other than adenocarcinoma or squamous cell carcinoma, a pathologic T stage more than T1, old age (> or =70 years) and no mediastinoscopic biopsy. During the follow-up, 79 patients (46.5%) experienced tumor recurrence, including loco-regional recurrence in 20 patients (25.3%) and distant metastasis in 56 (70.9%). The 5-year recurrence-free survival rate was 33.7%. CONCLUSION: Based on our findings, the survival was good for patients with unexpected N2 non-small cell lung cancer and who underwent initial pulmonary resection without neoadjuvant therapy. A prospective comparative analysis is needed to obtain more conclusive and persuasive results.

Ethylene glycol is a sweet-tasting liquid with industrial use as a solvent or as a starting reagent in chemical processes. Physicians are familiar with ethylene glycol because it is the major component of many antifreeze solutions and is taken in suicide attempts or, more often inadvertency. its metabolites may cause severe intoxication. Unfortunately, its metabolites are highly toxic and require rapid treatment Treatment involves correction of metabolic acidosis, ethanol administration and enhancement of elimination. The most commonly used elimination technique is hemodialysis We describe an 21-year-old man with acute renal failure due to ingestion of antifreeze that contained ethylene glycol. He was transferred to our hospital because of aggressive management The recovery of our patient with severe ethylene glycol intoxication illustrates that aggressive and early treatment can prevent mortality and morbidity.

Menkes disease, so called kinky-hair syndrome, is a rare, genetic and progressive neurodegenerative disorder. It is caused by a mutation in the ATP7A gene, which codes for the copper transporting ATPase in the cell organelles. The dysfunction of many copper-dependent enzymes results in low concentration of copper in some tissues and accumulation of copper in others. We report a boy presented with kinky hairs, developmental delay, hypotonia and connective tissue abnormalities at the age of 4 months. Despite the treatment with various antiepileptic drugs, atonic seizures still persisted. At the age of 7 months, his atonic seizures was changed into extensor spasms with modified hypsarrhythmia for some years. The seizure were controlled by topiramate and vigabatrin. At the age of 22 months, serum copper and ceruloplasmin rechecked as 17 ug/dL(80-150 ug/dL) and 7.3 mg/dL(20-46 mg/ dL) respectively. The gene study showed ATP7A mutation and the patient was diagnosed as Menkes disease so that copper-histidine was daily injected. We experienced a case of a 4-month-old boy with Menkes disease and infantile spasm, confirmed by ATP7A mutation.
