Solitary circumscribed neuroma is a benign nerve sheath tumor of unknown etiology. Clinically, it appears as a long-standing, solitary, asymptomatic, skin-colored papule or papulonodule. It has been found predominantly on the face in both sexes, mostly in middle age. A 53-year-old female patient visited our department because of a nodule on the side of the distal interphalangeal joint of the left second finger. A biopsy specimen showed a well-circumscribed, partially encapsulated tumor composed of interlacing fascicles of spindle cells. Neither pleomorphism nor mitosis was found. Immunohistochemical stainings for vimentin, neuron specific enolase (NSE) and epithelial membrane antigen (EMA) were positive, but negative for S-100 protein and smooth muscle actin (SMA). We herein report an uncommon case of solitary circumscribed neuroma.

Contact urticaria refers to a wheal-and-flare response occurring on the application of chemicals to intact skin. When contact urticaria is accompanied by systemic symptoms, it is known as the urticaria syndrome. Fourteen cases of cefotiam-induced contact urticaria have been reported in the foreign literature, but no such case, as far as we know, has been described in the Korean dermatology literature. We report a case of contact urticaria syndrome occurring in a 23-year-old nurse due to occupational contact exposure to cefotiam. She experienced generalized urticaria, itching of the skin, difficulty in breathing, and abdominal pain, when she was preparing an injection of cefotiam. An open patch test showed positive reactions to cefotiam, cefmetazole, and ceftriaxone. Since avoiding cefotiam, the symptoms disappeared and did not recurred.

Contact urticaria refers to a wheal-and-flare response after cutaneous exposure to certain chemicals. If contact urticaria is accompanied by systemic symptoms, it is referred to as contact urticaria syndrome. Herein we report two cases of contact urticaria syndrome occur-ring in nurses due to occupational exposure to cefotiam.

Complications of penile prosthesis include malfunction, infection and patient dissatisfaction. Herein, a rare complication of a retained reservoir having eroded into the bladder after the removal of the penile components of a three-piece penile prosthesis, is reported. A 39-year-old man complained of irritative voiding symptoms. The symptoms had developed 4 years after the removal of the penile components of the prosthesis. The erosion of the reservoir into the bladder was discovered incidentally during the treatment of bladder calculi. The reservoir was removed by an open vesicolithotomy.

Several reports on burst fractures of the thoracolumbar spine have noted that the neural canal encroachment caused by bone in the canal did not correlate with the neurologic status of the patient. But in the thoracolumbar spine the average percent compromise was significantly higher in those patients with complete and incomplete lesions, compared with those patients with no neural deficits. In this study, we evaluated 38 patients with unstable thoracolumbar fractures, operated from March 1989 to February 1993 to know the amount of neural canal compromise, demonstrated on computed tomography scans with neurologic status, level of injury and type of fractures. Among them 22 patients had neurologic deficit and 16 did not neurologic deficit. The results were as follows; 1. 19(76%) of 22 patients with disruption of the posterior spinal elements had neurologic defictis. 2. In the group with neurologic deficits, the stenotic ratio was 44% at the epiconus level, 55% at the conus medullaris, level and 63% at the cauda equna level. 3. The average A-P diameter of the bony fragments retropulsed into the spinal canal was 4.5mm at the epiconus level, 5.2mm at the conus medullaris level and 6.0mm at the cauda equina level. 4. Unstable bursting fracture and fracture dislocation showed higher incidence of neurologic injury and percentage of spinal stenotic ratio than those of flexion distraction and wedge compression fracture. In conclusion, the higher the level of the injured vertebrae, the smaller the size of the retropulsed fragment needed compromise the neural tissues. We suggest that it is necessary to get enough decompression for restoration of spinal canal and recovery of neurological function and computed tomography was more sensitive than any other modality in detection the reduction of the retropulsed bony fragment into spinal canal.

PURPOSE: This study was undertaken to correlate the CT and histopathologic findings of abscess wall. MATERIALS AND METHODS: The CT findings of 12 patients with pathologically proven brain abscess were retrospectively analyzed with particular attention to the thickness, smoothness and uniformity of enhancing abscess wall, and the results were correlated with histopathologic findings. RESULTS: Two patients with acute cerebritis showed an isodense ring on non-contrast CT(NCCT), but a true capsule formation could not be identified at pathologic examination. Six other patients with isodense ring on NCCT consisted of early to late cerebritis(3 cases), late cerebritis to early capsule(1 case), early capsule(1 case), and late capsule(1 case). These 6 cases showed ring enhancement on contrast enhanced CT(CECT) and true capsule formation pathologically. There was no isodense ring on NCCT in the remaining four patients. They consisted of early to late cerebritis(2 cases), late cerebritis(1 case), and late cerebritis to early capsule formation(1 case). These also showed ring enhancement on CECT and true capsule formation pathologically. CONCLUSION: We found that it is difficult to predict the exact stage of brain abscess on preoperative CT findings. It is suggested that clinical findings and sequential dynamic CT may provide more detailed informations for evaluation of abscess staging.

PURPOSE: Natural orifice transluminal endoscopic surgery (NOTES) is a new surgical option using endoscopic advancement to the peritoneal cavity through the stomach, colon, vagina, or urinary bladder without an abdominal wall scar (incision). The aim of this study was to assess the feasibility of transgastric gastroscopic intra-abdominal exploration with gastric incision and closure before the NOTES would be done. METHODS: Under general anesthesia of a female dog, one-channel gastroscope was advanced to the stomach and the lumen was irrigated with anti-bacterial solution. The anterior wall of the antrum was incised by about 1 cm with a needle knife; then, the gastroscope was advanced into the peritoneal cavity. An exploration of the entire intra-abdominal cavity was performed. RESULTS: We were able to evaluate the stomach, the greater omentum, the diaphragm, the peritoneum, the urinary bladder, the bowel, the spleen, the liver, the gallbladder, the uterine horn, the uterine body, and the vagina, but could not evaluate the ovary, the kidney, and the pancreas. The observation of the abdominal cavity was followed by the gastric wall closure with a 135o endoclip. The dog was recovered after confirmation of secure closure of the incision site. CONCLUSIONS: Transgastric incision, closure, and abdominal exploration are feasible without an abdominal wall scar, and the NOTES can be one option for future abdominal operations in humans and needs to be further investigated.
