Wild-caught box turtles (Terapene carolina carolina) with aural abscesses were observed over a period of several years. Histopathologic evaluation of epithelial tissues (conjunctiva, pharynx, trachea, auditory tube) revealed mucosal hyperplasia and squamous metaplasia, and accumulated keratin-like material in the middle ear cavity. These manifestations suggested the possibility of vitamin A deficiency. A nonsignificant trend toward reduced serum and hepatic vitamin A levels was observed in turtles with abscesses (mean serum and hepatic vitamin A levels 71 and 49% of respective levels in turtles without abscesses). Three organochlorine (OC) compounds (alpha-benzene hexachloride, heptachlor epoxide, and oxychlordane) and total (microg/g) OC compounds were significantly higher in turtles with abscesses compared with turtles without abscesses. No OC compounds were higher in turtles without abscesses compared with turtles with abscesses. These data suggest a possible effect of environmental chemicals on metabolism or utilization of vitamin A in wild box turtles, resulting in hypovitaminosis A.
A 40-year-old man with a history of schizophrenia and inflammatory soft tissue lesions after self-injection of elemental mercury presented to the Emergency Department. Multiple skin abscesses associated with fever required operative debridement. An incidental finding of oral mercury ingestion was followed clinically and did not result in complications. Exposure to elemental mercury through injection or ingestion is an uncommon event, but one the Emergency Physician may encounter. Subcutaneous mercury injection should be managed with local wound debridement, whereas ingestions are rarely of clinical significance.
BACKGROUND: A recent investigation demonstrated a high incidence of epidural abscess secondary to epidural catheterization and a 50% frequency of neurologic deficits. We studied short- and long-term neurologic outcome in patients operated for spinal epidural abscess after epidural analgesia. METHODS: Nineteen patients who had undergone neurosurgical decompression and drainage of a spinal epidural abscess during a 5-year period at three neurosurgical departments in East Denmark were identified by manual review of operating lists. RESULTS: Median epidural catheterization time was 8 days (range 3-44). Preoperatively 12 patients suffered from inferior paraparesis, one had irradiating pain from the back, and 6 patients had no neurologic deficits. Postoperatively 2 patients had recovered, but 3 other patients had deteriorated; therefore, 13 patients were discharged with paresis/plegia. Seven patients died during a median follow-up time for all patients of 41.6 months. One patient recovered completely, and one suffered from minor deficits. The remaining patients suffered from paraparesis/plegia or bladder/bowel dysfunction. CONCLUSION: Overall recovery rate for patients with paresis/plegia after epidural abscess was 20%. No patients with paresis/plegia following a thoracic abscess recovered in contrast to a 50% recovery rate for patients with lumbar epidural abscess. The majority of long-term survivors had severe neurologic deficits. Abscess formation contributed to one death.
