1/42. When a mastoid swelling is not mastoiditis.

    A case is reported of swelling over the mastoid process due to subgaleal abscess possibly secondary to trivial cutaneous trauma. The diagnosis was difficult as subgaleal abscess is an extremely rare condition especially after the advent of the antibiotic era. The route of entry of the infection to the subgaleal space was unclear as there was no skin puncture. The absence of substantial trauma excluded subgaleal haematoma as a precondition. We would like to discuss the possible aetiologies and the management of this rare case in the light of the limited information available in the world literature.

2/42. Mediastinal abscess successfully treated by percutaneous drainage using a unified CT and fluoroscopy system.

    We report two patients with mediastinal abscess developing after surgery for oesophageal cancer who were treated by percutaneous drainage using a unified CT and angiography system, which allows both CT and fluoroscopy to be conducted with the patient on the same bed. Fine needle puncture is performed under CT guidance and this needle is used as a tandem for insertion of the drainage needle under fluoroscopic guidance, making safe puncture possible whilst confirming the position of the needle tip. Moreover, contrast medium can be injected from the drainage tube, allowing the extent of the abscess cavity to be determined by fluoroscopy and CT, thereby making accurate drainage possible.

3/42. staphylococcus aureus subcutaneous abscess complicating acupuncture: need for implementation of proper infection control guidelines.

    We report a case of staphylococcus aureus subcutaneous abscess centered over the Jizhong acupuncture point (DU 6) which lies along the Du (Back midline) meridian after acupuncture at the corresponding acupuncture point for low back pain. The patient recovered after surgical debridement and drainage and 5 weeks of cloxacillin therapy. Among the 16 anecdotal case reports of pyogenic bacterial infections complicating acupuncture described in the English literature (medline Search 1996-2002), S. aureus was documented to be the causative agent in 9 (56%). Three patients had septic arthritis, 2 had chronic osteomyelitis, 2 had abscess formation, 1 had chondritis, and 1 had infective endocarditis. Five patients had S. aureus bacteremia. All patients who recovered required prolonged antibiotic treatment of 5-6 weeks, and 6 required drainage and/or debridement. overall, 3 patients (30%) died. S. aureus causes significant morbidity and mortality in patients who receive acupuncture treatment. More resources should be spent on implementation of proper infection control guidelines, as the money lost due to prolonged hospitalization and medication would far exceed that used for implementation.

4/42. Tuboovarian abscess caused by Atopobium vaginae following transvaginal oocyte recovery.

    A 39-year-old woman with tubarian sterility fell ill with acute pelvic inflammatory disease 2 months after transvaginal oocyte recovery. laparotomy revealed a large tuboovarian abscess, from which Atopobium vaginae, an anaerobic gram-positive coccoid bacterium of hitherto unknown clinical significance, was isolated. The microbial etiology and the risk of pelvic infections following transvaginal punctures are discussed.

5/42. Multiloculated prostate abscess: treatment with transrectal ultrasound guided transrectal needle aspiration and lavage with the saline and antibiotic.

    Prostatic abscess is a rare but nevertheless serious disease. It should be diagnosed at an early stage by the combination of clinical examination and transrectal ultrasound, and drained. We treated a 79-year-old case with multiple prostate abscesses (PAs) by using lavage of the saline and antibiotic (cefoxitin) after transrectal ultrasound-guided transrectal puncture and aspiration. We are presenting the transrectal ultrasound images of pre- and postmedication, where we achieved complete success and no relapse was seen in follow-up of 1 year.

6/42. Acute spinal epidural abscess and spinal leptomeningitis: report of 2 cases with comparative neuroradiological and autopsy study.

    A 21-year-old male developed back pain, fever, and rapidly progressive quadriparesis. Lumbar tap yielded frank pus which was confirmed on magnetic resonance imaging (MRI) to be located mainly in the cervical epidural space. Conservative antibiotic remedy was partially effective for restoration of the neurological deficits. A 82-year-old female noticed low-back pain which was rapidly accompanied with clouding of consciousness, paraplegia, and sphincter disturbances. Lumbar puncture revealed thick pus which was best depicted on MRI in the thoracolumbar subarachnoid space. At autopsy, spinal subarachnoid abscess or leptomeningitis was confirmed, and a spinal infarction previously unrecognized on MRI was found. Usefulness and shortcomings of MRI in the diagnosis of paraspinal infections are discussed.

7/42. Infective tricuspid valve endocarditis due to abscess of an endogenous arteriovenous fistula in a chronic hemodialysis patient.

    patients on chronic hemodialysis are at high risk for endocarditis due to prosthetic access devices. Right-sided endocarditis without any predisposing factors is rare in dialysis patients. A 76-year-old female, who had chronic renal failure had been treated by hemodialysis and had a permanent pacemaker implanted, was admitted to our hospital with a high fever and lumbago after abscess formation at an autogenous arteriovenous fistula for hemodialysis. methicillin Resistant staphylococcus aureus was identified by blood culture examination. echocardiography revealed vegetation attached to the tricuspid valve. Chest X-ray and perfusion lung scintigraphy showed pulmonary infarction, perhaps due to vegetation-derived emboli. Computed tomography also showed pyogenic spondylitis in L4 and L5. Repeated vascular punctures even of autogenous grafts expose dialysis patients to bacteremia and imply a higher risk of infectious endocarditis.

8/42. A subdural abscess and infected blood patch complicating regional analgesia for labour.

    We report two very unusual cases of infection complicating labour analgesia. The first case was a sub-dural abscess presenting with deep-seated backache seven days after combined spinal-epidural analgesia for labour. The second was a painful lumbar swelling and septicaemia that presented three days after a blood patch for a post dural puncture headache. Because of their complicated and unusual presentation, the diagnosis and management of both were initially delayed.

9/42. A paraspinal abscess following spinal anaesthesia for caesarean section and patient-controlled epidural analgesia for postoperative pain.

    We present a rare case in which a healthy parturient developed a paraspinal abscess after spinal anaesthesia for caesarean section and epidural analgesia for postoperative pain management. The catheter was in situ for 58 h. Backache was the initial and major symptom. A concealed course with no neurological deficit resulted in a delayed diagnosis and treatment in this case. The infection was not diagnosed until 20 days after the removal of the epidural catheter when there was a purulent discharge from the epidural puncture site. Surgical drainage was required. Anaesthesiologists should be aware that serious epidural analgesia-related infections can happen in extra spinal-epidural spaces. Vigilance for these infections, especially in postpartum patients with backache, is needed.

10/42. First identification of clostridium celerecrescens in liquid drained from an abscess.

    We present the first report on the characterization of clostridium celerecrescens isolated from liquid drained via abscess puncture from a 45-year-old man. The organism was identified by sequence comparison of 16S rRNA genes.
