Abdominal actinomycosis is very rare infectious disease and seldom reported as a cause of abdominal mass. This disease is diagnosed by pathologic findings and culture result but it is very difficult to differentiate with other granulomatous illammatory disease, diverticular disease, malignancy, etc. The radiologic findings were non-specific and CT scan revealed the inflammatory mass with multiple small abscesses and fibrous change. The treatment of choice for actinomycosis is medical treatment with penicillin but surgical intervention may be needed when complication such as obstruction, fistula formation, abscess formation develop. We report a patient with abdominal actinomycosis that presented with transverse colonic obstruction and severe abdominal wall inflammation. This patient had no past operative history but got intrauterine contraceptive devices during last 10 years. We treated this patient by surgical resection and antibiotic therapy.

Superficial angiomyxoma is a comparatively rare dermal and subcutaneous tumor. We report a case of superficial angiomyxoma of the thumb in view of its rarity and typical light and electronmicroscopic features. The patient was a 46-year-old male. who presented with an asymptomatic, slowly enlarging mass that developed in the left thumb over the 5 years. He had a history of trauma and electric burn in the same area 20~30 years ago. Simple X-ray and magnetic resonance imaging revealed 35x30mm, mass with destruction of distal phalangeal bone. On operation, the lesion was moderately well circumscribed and soft with lobulated nodules that elevated the overlying skin and destroyed the underlying bone. The cut surface of the mass was glistening and slimy. The mass was whitish gray and lobulated. Bony involvement was not present. Microscopically, the tumor was composed of stellated and spindle shaped stromal cells which were scattered throughout myxoid ground substance. Neither nuclear hyperchromasia nor plemorphisam was present. Small to medium sized thin walled blood vessels were scattered. There was a scanty infiltrate of inflammatory cells. The S-100 protein immunostaining was negative in tumor cells. On electron microscopy, the cytoplasm of the stromal cells contained well developed rough ednoplasmic reticulums and other features that indicated differentiation toward fibroblasts.

We reviewed five cases of Uterine leiomyomas, each with a conspicuously, yellow cut surface, among 198 consecutive cases of surgically removed uterine leiomyomas. Their gross findings were not significantly different from ordinary leiomyomas except for their pale to bright Yellowish cut surface. Microscopically, multiple small clusters of clear cells were widely scattered in otherwise hypercellular leiomyornas in 4 of the 5 cases. Of those, one case gave a positive reaction of Oil-Red O stain. Ultrastructurally, clear cells corresponded to the degenerating smooth muscle cells with intracytoplasmic lipid vacuoles. The rest of cells showed myofibers undergoing varying degrees of degeneration. Focal accumulation of foamy histiocytes was associated with carneous degeneration in one case. We conclude that the yellowish leiomyoma of the uterus seems, in part, to reflect accumulation of a lipid substance in degenerating hypercellular leiornyoma, or possibly collections of xanthoma cells in secondary degeneration.

BACKGROUND: Hypotension occurs frequently after epidural anesthesia. Intravenous fluid or vasopressors are among treatment methods to many suggested causes. This study was undertaken retrospectively to determine if the age, weight and height of parturients are related to the local anesthetic dosage in epidural anesthesia for the cesarean section, and if the dosage of local anesthetic influence the change of blood pressure and the requirement of fluid or epherine. METHODS: Sixty-nine parturients were studied by reviewing patients' anesthetic records. During lumbar epidural anesthesia to T4 sensory level, all patients were monitored with mean arterial blood pressure, and prevented from hypotension by administration of Ringer's lactated solution. But if hypotension has been sustained in spite of rapid fluid loading, intermittent ephedrine was injected. We studied the correlation of local anesthetic dosage, decrement of mean blood pressure and total required intravenous fluid volume, and difference of these variables between cases using ephedrine and not using. RESULTS: The volume of local anesthetic to achieve a T4 sensory level was 21.20 3.81ml, which did not correlate with age, weight and height, and did not influence the decrease of mean blood pressure and the volume of administered fluid. But the patients (n=30) who needed ephedrine were adminstered significantly larger dose of the local anesthetic and showed more decrease in the mean blood pressure than those (n=39) who did not. CONCLUSIONS: The dose requirement of local anesthetic during epidural anesthesia for the cesarean section is not determined by the age, weight and height of parturients. But when larger dose of local anesthetic is administered, the patients seem to be more hypotensive and need ephedrine as well as intravenous fluid administration.

Background: Bupivacaine was introduced to be a long-acting spinal anesthetic agent. It has been argued about whether the addition of epinephrine prolongs the bupivacaine action or not. The aim of this present investigation was to find out the effect of additional epinephrine on spinal anesthesia with bupivacaine. Methods: 47 patients undergoing an operation on lower extremity were randomly allocated to 2 groups. All patients were anesthetized by subarachnoid block with 0.5% bupivacaine in 8% glucose, which was mixed with 0.2 ml of normal saline in group non-E (n=24) and 0.2 ml of 1:1,000 epinephrine in group E (n=23). We evaluated blood pressure and heart rate, the sensory and motor blockade and voiding time after spinal anesthesia. Results: The systolic blood pressure (SBP) at 8 and 10 min after anesthesia were lower in group non-E than in group E (p<0.05). The trend of decreasing diastolic blood pressure was similar in both groups. The heart rate(HR) at 2 min after anesthesia was lower in group non-E than in group E (p<0.05). The sensory block in T10 was produced faster in group non-E (7 min) than in group E (11 min)(p<0.05). And the maximal sensory block level and its reaching time was T7 and 14 min in group non-E, and T8 and 17 min in group E (p=0.12, p=0.11). Two segment regression time was 124 min in group non-E, and 184 min in group E (p=011). The onset time of motor block to Bromage scale 3 was 12 min in group non-E and 16 min in group E (p=0.06). The recovery time from complete motor block to Bromage scale 1 after maximal motor block was 263 min in group non-E, and 278 min in group E. The time at which patients voided after anesthesia was 469 min in group non-E, and 466 min in group E. Three patients urinated by using a urinary catheter in each group. Conclusions: The addition of epinephrine to bupivacaine for spinal anesthesia can slow the decrease in SBP and increase the HR at early stage of anesthesia, and slow the sensory block.
