Osteoma is a slow-growing benign tumor composed of mature bone. Osteoma of the nose and paranasal sinuses is usually asymptomatic and most commonly occurs in the frontal sinus, followed by the ethmoidal and maxillary sinus. The occurrence in the sphenoidal sinus and nasal cavity is very rare. We present a case report of a patient with an isolated osteoma in the right nasal cavity presenting with nasal obstruction.

Pseudomeningocele after spine surgery can cause various symptoms, but it can also be silent. We experienced 3 cases of pseudomeningocele with different symptoms and we analyzed the characteristics of each case. A small pseudomeningocele without connection to the subarachnoidal space can show no symptoms. A pseudomeningocele with a small dural tear and it's abutted on the duramater at a small portion can produce sciatica and limitations of straight leg raising due to adhesion of the cauda equina around the dural tear. In addition, a large pseudomeningocele with a big dural and lamina defect can produce back tenderness furthermore, a patient with such a lesion can have low back pain and leg pain that are aggravated by an increment of abdominal pressure or by impact to the body and even by walking. Pseudomeningocele should be suspected when symptoms recur after spine surgery and especially in the case of dural tear during an operation

BACKGROUND: In patients after acute myocardial infarction, signal-averaged electrocardiography is used as the one of the non-invasive methods for the prediction for ventricular arrhythmia, one of the causes ofn death in acute myocardial infarction. Signal-averaged electrocardiography has allowed the identification of low-amplitude, high-frequency signals(late potentials)in the terminal portion of the QRS complex. They are thougt to be occured in the portion of electrophysiologically unstable myocardium. The presence of late potentials identifies regions of delayed conducton in the elctrophysiologically unstable border zone of an acute infarction. These electrophysiologic change of myocardium is influenced by the patency of infarct-related artery. A patent artery is associated with electrical stability of myocardium, decreased in cidence of late potentials and improved survival. METHODS: 58 patients of acute myocardial infarction underwent signal-averaged electrocardiography, coronary angiography within 10 days after AMI, 20 of healthy persons underwent signal-averaged electrocardiography. RESULTS: In patent group, late potentials were recorded in 7 of 38 patients(18%) as compared with 13 of 20 patients(65%) of non-patent group. The statistically significant parameters of signal-averaged electrocardiography beteen patent and non-patent group were filtered total QRS duration(TQRS, 106.7+/-20.9msec), high frequency low amplitude signal (HLAS, 30.8+/-7.5 vs 41.3+/-16.5 msec)with HLAS being the most powerful varialble in the model. CONCLUSION: These results suggest that the patency of infarct-related artery is associated with electrophysiologic stability of myocardium and signal-averaged electrocardiography is one of the useful non-invasive method in risk stratification of acute myocrdial infarction.

We report a case of a 44-year-old patient with paralysis of the left leg who had a thoracic epidural catheterization after general anesthesia for abdominal surgery. Sensory losses below T10 and motor weakness of the left leg occurred after the surgery. Magnetic resonance image study demonstrated a well-defined intramedullary linear high signal intensity lesion on T2-weighted image and low-signal intensity on T1-weighted image in the spinal cord between T9 and L1 vertebral level, and enhancements of the spinal cord below T8 vertebra and in the cauda equina. Electrodiagnostic examination revealed lumbosacral polyradiculopathy affecting nerve roots below L4 level on left side. We suggest that the intrinsic spinal cord lesion and nerve root lesion can be caused by an epidural catheterization with subsequent local anesthetic injection.

Giant keratoacanthoma is an uncommon variant of keratoacanthoma, which may increase to a diameter of several centimeters. Although keratoacanthomas usually resolve spontaneously, giant keratoacanthoma can be invasive and destructive. A 49-year-old man presented with a 5-year history of multiple large hyperkeratotic and crusted plaques and nodules on sun-exposed areas such as the face, ear, hand, and forearm. Some lesions involuted spontaneously, whereas others became rather enlarged. The biopsy specimen revealed horn-filled crater formation, epidermal extending resembling a buttress, and an eosinophilic glassy appearance in the keratinocytic cytoplasm. We treated the lesions with acitretin, and they almost completely resolved after 13 weeks. Here we describe a case of multiple giant keratoacanthoma treated with acitretin.

PURPOSE: Natural orifice transluminal endoscopic surgery (NOTES) is a new method of accessing intracavitary organs in order to minimize pain by avoiding incisions in the body wall. The aim of this study is to determine patients' acceptance of NOTES in Korea and to compare their views about laparoscopic surgery and NOTES for benign and malignant diseases. MATERIALS AND METHODS: The target number of total subjects was calculated to be 540. The subjects were classified into 18 sub-groups based on age groups, gender, and history of prior surgery. The questionnaire elicited information about demographic characteristics, medical check-ups, diseases, endoscopic and surgical histories, marital status and childbirth, the acceptance of NOTES, and the preferred routes for NOTES. In addition, the subjects chose laparoscopic surgery or NOTES for a hypothetical cholecystectomy and rectal cancer surgery, and responded to questions regarding the acceptable complication rate of NOTES, the appropriate cost of NOTES, and the reason(s) why they did not select NOTES. RESULTS: 486 of 540 patients (90.0%) who agreed to participate in this study completed the questionnaire. NOTES was preferred by the following patients: elderly; a history of treatment due to a disease; having regular check-ups; and a history of an endoscopic procedure (p<0.05). The most preferred route for NOTES was the stomach (67.1%). Eighty-four percent of the patients choosing NOTES responded that the complication rate of the new surgical method should be the same or lower than laparoscopic surgery. Vague anxiety over a new surgical method was the most common reason why NOTES was not selected in benign and malignant diseases (64% and 73%), respectively. CONCLUSION: Patients appear to be interested in the potential benefits of NOTES and would embrace it if their concerns about safety are met. We believe that qualified surgical endoscopists can meet these safety concerns, and that NOTES development has the potential to flourish.

A patient with nevus sebaceous showing linear or wide distribution can present with a triad of nevus sebaceous, seizures, and mental retardation. Most of those cases are classified as sebaceous nevus syndrome. Ophthalmological, skeletal, and other abnormalities may also be present. A male weighing 3,580 g was born at the gestational age of 38 weeks after a normal pregnancy. He was referred to the dermatologic department on the first day of life. He presented with yellow-orange and verrucous plaques on both sides of the temporal areas, face, neck, upper and lower extremities, and trunk. Skin biopsy specimens were taken from the scalp and right lower leg. Histologically, both specimens showed sebaceous gland hyperplasia, absence of mature hair follicles, infundibular cystic structures, and apocrine glands. Brain magnetic resonance imaging, transthoracic echocardiography, abdomen ultrasonography, and routine laboratory investigations were performed and showed nonspecific findings. The patient did not show seizure activity at 19 days of observation, and he is now on close observation. We herein report a very rare case of systematized nevus sebaceous presenting at birth.
