Arytenoid subluxation or recurrent laryngeal nerve paralysis may result from injury to the larynx following endotracheal intubation or blunt laryngeal trauma. Early diagnosis is important for appropriate treatment and better prognosis. A 62-years-old man was admitted for cholecystectomy. He was intubated without any difficulty and nasogastric tube was inserted with the help of laryngoscope and Magill forcep before surgery. He had a weak voice and hoarseness after atraumatic extubation and those symptoms did not improve even 2 days after. Indirect laryngoscopy, videolaryngotelescopy, electromyography(EMG) and computed tomographic findings revealed anterior, inferior subluxation of left cricoarytenoid cartilage associated with left thyroarytenoid muscle denervation and resultant unilateral vocal cord palsy. Conservative treatment for 40 days after the operation and follow-up examination was done. The voice quality was improved and indirect laryngoscopy examination showed that right vocal cord crossed midline in a attempt to meet its paralyzed counterpart on phonation.

In a series of 20 young rats, three cortical lesions were made in each hemisphere. Two of these lesions were filled with avitene and gelfoam, while the third was left empty as a control. The animals were killed successively on weeks 1, 2, 4 and 8 after the operation. The results were as follows : 1) Although there was no difference in the type of tissue reactions, avitene was more rapid and profound than gelfoam in the process and degree of inflammatory reaction at the same periods. 2) Avitene biodegradaded more rapidly than gelfoam. 3) The extent of fibrosis and adhesion to the surrounding brain tissues were not grossly different between these two agents but more profound histopathologically in avitene at the same periods. With these results, we could conclude that the avitene was superior to the gelfoam as the hemostatic agent in neurosurgical area.

Cutaneous horns of the penis are rare. We report a case associated with squamous cell carcinoma in a 56-year-old male. A gradually enlarging nodule had been on the glans penis for four years. He had suffered from an erythematous crusted tumor mass and horny excrescence on the glans penis which recurred and was aggravated after excision of the nodule seven months ago. Histopathologic findings of the lesions showed characteristic findings of squamous cell carcinoma and cutaneous horn. In situ DNA hybridization for human papillomavirus types 6, 11, 16, 18, 32, and 33 were all negative. The tumor mass were surgically excised and we have not found any sign of recurrence since then.

Varicella zoster virus (VZV)-induced brachioplexitis is a rare disease, characterized by exacerbating ipsilateral upper extremity pain, muscular weakness, and delay in recovery. We report a 54-year-old female patient who made an early recovery from VZV-induced brachioplexitis via the treatment with stellate ganglion blocks, which may have prevented pain sensation, vasoconstriction, and nerve scarring during the early treatment period.

BACKGROUND: The purpose of this study was to examine the effects of a single administration of vascular endothelial growth factor (VEGF) in promoting the angiogenesis and thereby reducing the formation of capsular contracture. METHODS: We treated 24 female Sprague-Dawley rats with (1) 5 mM Tris Buffer and 150 mM NaCl 0.1 cc, (2) VEGF 15 µg/0.1 cc, (3) VEGF 150 µg/0.1 cc during placement of the implant, or (4) VEGF 150 µg/0.1 cc and VEGF 300 µg/0.2 cc. We histopathologically measured the thickness of the capsule and the number of blood vessels. RESULTS: All experimental groups had a significant difference in the thickness of the capsule compared to the control group (P<0.001). There was no significant difference between experimental group 2 and experimental group 3. The number of blood vessels formed around the capsule was significantly greater in all the experimental groups compared with the control group (P<0.05). There was no significant difference between the experimental groups. There was a significant negative correlation between the thickness of the capsule and the number of blood vessels (Spearman's correlation coefficient, 0.2732; P<0.0001). CONCLUSIONS: A single administration of VEGF reduced formation of the capsule and increased the vascularity around the implant, supporting the hypothesis that prevention of tissue ischemia can be a treatment strategy for capsular contracture.

OBJECTIVES: In order to standardize the CRP, ESR and WBC count after three types of spinal surgery and get clinical usefulness from these laboratory dadas after spinal surgery and clincal usefulness of laboratory datas. MATERIAL AND METHODS: Three groups of patients(microdisectomy, anterior and posterior fusion) were chosen for the study. CRP, ESR and WBC levels were prospectively determined before surgery and at days 1-5, 10, 14,21 and 42 after surgery. RESULTS: In all patients, preoperative normal CRP level(<10mg/L) increased, reaching peak levels on the second day after anterior fusion(84.6mg/L), and at the third day after microdiscectomy(54.5mg/L) and posterolateral intercorporal fusion(152.2mg/L), with normalization in 5-10 days. Preoperative normal ESR level increased to peak level on the forth day after microdiscectomy(33.0mm/hr), and increased double peak levels after anterior(postoperative days 2&5) and posterolateral intercorporal fusion(postoperative days 3&5). ESR followed by a slow and irregular decrease, and at 42 days after surgery often remained elevated. WBC increased to variable peak level within normal limit in all patients. CONCLUSIONS: The rapid decline in CRP will probably be interrupted by a second rise or persisting elevation if infection occurs. CRP is presumably a better test than ESR for early detection of postoperative infection.

Rotatory fixation of the atlantoaxial joint is relatively rare in adults but somewhat more common in children. Most of them are reduced spontaneously or after traction. However, combined rotatory injury of atlantoaxial joint and unilateral occipitoatlantal subluxation is a rare disease, and it is often difficult to diagnose accurately. Because the craniovertebral junction is complex and patients with combined atlantoaxial rotatory fixation (AARF) and occipitoatlantal subluxation has a less rotated head than patients with pure AARF. And injury of the occipitoatlantal and atlantoaxial joint can often result upper cervical instability, so early diagnosis is very important. We present a case of the combined AARF and unilateral counter occipitoatlantal subluxation after minor trauma.

Mental deterioration and signs of cerebellar dysfunction developed 5 years after lateral ventricle shunting in 36-year-old hydrocephalic female patient. Fourth ventricle enlargement was seen on CT scan. Reevaluation of the cerebrospinal fluid pathways with metrizamide ventriculography showed isolated fourth ventricle with aqueductal stenosis. Shunting of the fourth ventricle with an Y-connector returned the patient to normal neurological status.
