1/3323. Obturator internus muscle abscess in children: report of seven cases and review. Obturator internus muscle (OIM) abscess is an uncommon entity often mistaken for septic arthritis of the hip. We describe seven children with OIM abscess and review seven previously reported cases. The most common presenting symptoms were hip or thigh pain (14 patients), fever (13), and limp (13). The hip was flexed, abducted, and externally rotated in 11 patients. magnetic resonance imaging and computed tomography (CT) were diagnostic for OIM abscess in the 14 patients. Associated abscesses were located in the obturator externus muscle (5 patients), psoas muscle (2), and iliac muscle (1). The etiologic agents were Staphylococcus aureus (8 patients), streptococcus pyogenes (2), neisseria gonorrhoeae (2), and enterococcus faecalis (1). Three patients underwent CT-guided percutaneous drainage, and three had surgical drainage. Three patients had ischial osteomyelitis in addition to OIM abscess. The 11 children with uncomplicated OIM abscess were treated for a median of 28 days. All patients had an uneventful recovery. ( info) |
2/3323. Pubic pain in athletes: a case due to an abscess in the obturator muscle. Pubic pain is a common symptom in soccer players. Its cause can be difficult to determine. We report a case in a 19-year-old soccer player who had an abscess in the obturator internus muscle. We are aware of only one similar report in the literature. Painful limitation of internal rotation of the hip and evidence of infection suggested the diagnosis, which was confirmed by magnetic resonance imaging. In a soccer player, a fever and groin pain do not always indicate osteitis pubis. Limitation of internal rotation of the hip should suggest a lesion in the obturator internus muscle. ( info) |
3/3323. Interesting radiologic findings in suprasellar mass lesions. Report of three cases. The authors report three quite rare lesions of the sellar/parasellar region. They are namely; pituitary abscess, cystic macroadenoma and osteochondroma. In none of the cases, the preoperative diagnostic priority was not same as the final histopathologic diagnosis. The radiologic findings of these pathologies are discussed with emphasis on differential diagnosis. ( info) |
4/3323. Abscess related to anabolic-androgenic steroid injection. One million individuals in the united states, predominantly males under 25 yr of age, are current or past users of anabolic-androgenic steroids. Fifty percent of these young adults administer their drugs intramuscularly, placing them at risk for infections related to injection. We present here a case report of an injection-related thigh abscess in a 26-yr-old anabolic steroid injector who did not use sterile injection technique and reported sharing multidosage vials with two other weightlifting colleagues. Reported infections associated with anabolic-androgenic steroid injection include abscesses attributable to mycobacterium smegmatis, Staphylococcus, Streptococcus, and pseudomonas organisms as well as hiv, hepatitis b, and hepatitis c. These infections are primarily related to nonsterile injection technique, shared injection equipment, and are avoidable with appropriate prevention techniques. education is needed to prevent infectious complications such as abscesses and blood-borne pathogens among anabolic-androgenic steroid injectors.

| We describe a 53-year-old man who developed a catheter-related epidural abscess 8 days after left upper lobectomy for lung cancer. methicillin-resistant staphylococcus aureus (MRSA) was detected in a culture of the epidural pus. magnetic resonance imaging was essential for the diagnosis of epidural abscess and for determining the extent of spread. The patient was treated by laminectomy and administration of appropriate antibiotics, with almost complete recovery, except for urinary retention. A literature search yielded 29 additional cases of catheter-related epidural abscess. The median duration of catheterization was 4 days and the median time to onset of the clinical symptoms after catheter placement was 8 days. Eleven of the 30 patients had some underlying disorders, including malignancy or herpes zoster, or were receiving steroids. Nine of the 10 patients with thoracic epidural abscess had persistent neurological deficits, whereas 12 of the 15 patients with lumbar epidural abscess showed a full recovery after treatment. Surgical decompression was not required in six patients without significant neurological deficits, who recovered following antibiotic treatment (four patients) or percutaneous drainage (two patients). Thoracic catheters are associated with a disproportionately high incidence of epidural abscess and persistent neurological sequelae following treatment. ( info) |
6/3323. Left leg paralysis in a renal transplant. The postoperative course of renal transplant patients is often complicated by opportunistic infection. Up to 4% of posttransplant infections are caused by nocardia species. We present an unusual case of a nocardial spinal cord abscess that caused left leg paralysis. ( info) |
7/3323. guideline of surgical management based on diffusion of descending necrotizing mediastinitis. BACKGROUND: Descending necrotizing mediastinitis resulting from oropharyngeal abscess, is a serious, life-threatening infection. Exisiting strategies for surgical management, such as transcervical mediastinal drainage or aggressive thoracotomic drainage, remain controversial. methods: Four patients, (three males and one female) were treated for descending necrotizing mediastinitis resulting from oropharyngeal infection. Two had peritonsillar abscesses, while the others experienced dental abscess and submaxillaritis. Descending necrotizing mediastinitis received its classification according to the degree of diffusion of infection diagnosed by computed tomography. mediastinitis in two cases, (Localized descending necrotizing mediastinitis-Type I), was localized to the upper mediastinal space above the carina. In the others, infection extended to the lower anterior mediastinum (Diffuse descending necrotizing mediastinitis-Type IIA), and to both anterior and posterior lower mediastinum (Diffuse descending necrotizing mediastinitis-Type IIB). The spread of infection to the pleural cavity occurred in three cases. RESULTS: The surgical outcome concerning each of the patients was successful. Radical cervicotomy (unilateral in three patients, bilateral in the other) in conjunction with mechanical ventilation with continuous postoperative positive airway pressure, was performed in all cases. tracheostomy was established in three patients and pharyngostomy in two. The two descending necrotizing mediastinitis-Type I cases were successfully managed with transcervical mediastinal drainage. The descending necrotizing mediastinitis-Type IIA case received treatment through transcervicotomy and anterior mediastinal drainage through a subxiphoidal incision. The patient with descending necrotizing mediastinitis-Type IIB required posterior mediastinal drainage through a right standard thoracotomy followed by left minimal thoracotomy. CONCLUSIONS: The mediastinal infection, the extent of which has been accurately determined by computed tomograms, necessitates radical cervicotomy followed by pleuromediastinal drainage. Situations where infection has spread to posterior medisatinum, particularly when it reaches in the level of the carina (descending necrotizing mediastinitis-type I), may not always require aggressive mediastinal drainage. In comparison, diffuse descending necrotizing mediastinitis-Type IIB demands complete mediastinal drainage with debridement via thoracotomy. Subxiphoidal mediastinal drainage without sternotomy may provide adequate drainage in diffuse descending necrotizing mediastinitis-Type IIA. ( info) |
8/3323. Intrathoracic suture abscess after lobectomy for early lung cancer. Intrathoracic suture abscess may occur around sutures on the pleura or in the lung parenchyma, although it is rare to encounter such cases clinically. We report on a 68-year-old woman with an intrathoracic (extrapulmonary) suture abscess, which was discovered on a chest x-ray film one year after right-middle lobectomy for early lung cancer. The abscess was removed surgically, and the postoperative course was uneventful. Pathological examination showed that it was caused by braided polyester sutures. ( info) |
9/3323. Lacrimal gland abscess: two case reports. BACKGROUND: Bacterial dacryoadenitis is rare and suppuration leading to abscess formation within the lacrimal gland has been very rarely reported in the antibiotic era. methods: The medical records and investigation results, including computed tomography (CT), of two patients with lacrimal gland abscess were reviewed. RESULTS: Two cases of lacrimal gland abscess, one a 28-year-old male and the other a 64-year-old female, are described. Both demonstrated a characteristic low-density area within an enlarged lacrimal gland on CT. The first case had been treated with antibiotics and the abscess, when drained, was sterile. The second case settled spontaneously. Neither patient suffered any sequelae of dry eye. CONCLUSIONS: Although rare, lacrimal gland abscess may still occur and may require surgical drainage if spontaneous resolution does not occur. ( info) |
10/3323. dermoid cyst with dermal sinus tract complicated with spinal subdural abscess. Spinal subdural abscess caused by spread of infection with the dermal sinus tract is rare in children. This article reports on a 1-year-old male with prolonged fever, progressive paraplegia, and bowel and bladder dysfunction resulting from a spinal subdural abscess secondary to an infected spinal dermoid cyst with a dermal sinus tract. This is the youngest patient to be reported having this condition. Surgical intervention was performed to find a tumor that had capsule and keratinlike contents. culture of the abscess was positive for escherichia coli and bacteroides vulgatus. He received 6 weeks of parenteral antibiotic treatment. This patient illustrates the importance of urgent radiologic examination, immediate surgical resection, and appropriate antibiotic therapy for spinal subdural abscess. ( info) |
