OBJECTIVE: There are few reports on the clinical outcomes of the percutaneous endoscopic lumbar discectomy(PELD) with laser for the treatment of far lateral lumbar disc herniation. The objective of this study is to assess the safety and efficacy of the PELD with laser for the treatment of far lateral lumbar disc herniation. METHODS: The clinical records of 42 patients who had far lateral lumbar disc herniation and underwent PELD with laser between January 1996 and August 2002 were analyzed retrospectively. There were 24(57.1%) males and 18(42.9%) females, with a mean age of 53(range, 26-73) years. The surgical procedure was performed via a posterolateral approach after induction of a local anesthesis. The clinical outcomes were measured with MacNabO s criteria. The mean follow-up period was 38(range, 5-77) months. RESULTS: Clinical outcomes were revealed as follows: excellent in 28 patients(66.7%); good in 11(26.2%); fair in 2(4.7%); and poor in 1(2.4%). Therefore, the percentage of successful(excellent and good) outcomes was 92.9%. There was no statistically significant variation in the success rates according to age and operation level(p>0.05). Before the introduction of the high resolution endoscope, the success rate was 90.3% but after upgrading to the high resolution endoscope, the success rate was 100%, and there was a statistically significant variation in the success rate(p<0.05). In all cases, there was no complication or recurrence. CONCLUSION: As a minimally invasive surgery, PELD with laser is a safe and efficacious procedure for the treatment of far lateral disc herniation.

Frequency of meningioma is reported to be 18 percent of all incidences of intracranial primary tumors, and tumor extension to the extracranial structures occurred in about 20 percent of intracranial meningiomas. Involvement of the middle ear is quite rare and meningioma in the middle ear can be seen either as a primary tumor or an extension of intracranial tumors. Since predominant symptoms of meningioma are hearing loss, otorrhea and other otologic symptoms, one can be mislead to chronic otitis media with diagnosis. Recently, we incidentally found a meningioma in the middle ear during chronic ear surgery in a 40-year-old female, who was confirmed by histopathologic diagnosis to have meningioma. We report herewith this case with the review of literatures.

Recurrent peritonitis is the major complication of continuous ambulatory peritoneal dialysis (CAPD) and a common reason for discontinuation of this form of therapy. Polymicrobial peritonitis by gram- negative organisms suggests intraabdominal pathology not directly associated with CAPD, necessitating early removal of catheter and/or abdominal exploration. The source of infection may still be gastrointestinal, especially in light of the polymicrobial gram-negative peritonitis and rarely be gastrointestinal malignancy. We recently experienced a case of 64-year-old woman with recurrent CAPD peritonitis by polymicrobial gram-negative organisms, originated from colon cancer. Colon cancer was confirmed by barium enema, abdominal CT and colonoscopic biopsy. She underwent right hemicolectomy and removal of catheter simultaneously. The biopsy revealed a moderately to poorly differentiated adenocarcinoma with abundant mucin production.

Cemento-osseous dysplasias are a group of disorders known to originate from periodontal ligament tissue and involve, essentially, the same pathological process. They are usually classified into three main groups: periapical, florid, and focal cemental dysplasias depending on their extent and radiographic appearances. Radiographically, florid cementoosseous dysplasia (FCOD) appears as dense, lobulated masses, often symmetrically located in various regions of the jaws. The best management for the asymptomatic FCOD patient consists of regular recall examinations with prophylaxis. The management of the symptomatic patient is more difficult. A case of FCOD occurring in a 52-year-old edentulous Korean female is reported which is rare with regard to race and sex.

There is increasing evidence that airway epithelial cells, when exposed to various gas-derived air pollutants, play an important role in airway inflammation by releasing inflammatory cytokines. However, there is little information on air pollutant-induced cytokine expression at the tissue level and on the role of sulfur dioxide (SO2), one of the major ambient air pollutants, in cytokine production. We studied whether or not a low concentration of sulfur dioxide induces an increase in tissue expression of interleukin-4 (IL-4), interleukin-8 (IL-8), and granulocyte/macrophage colony stimulating factor (GM-CSF). After exposing surgically obtained normal human nasal turbinates to 0.05 ppm SO2 for one hour, we conducted specific immunohistochemical staining to assess the tissue expression of each cytokine. We found that the percent expression of IL-8 and GM-CSF in the surface epithelium was significantly higher in each SO2-exposed tissue than in the matched control tissue. However, there was no significant difference in the number of submucosal IL-4-positive cells between exposed and control specimens. These results suggest that exposure to a low concentration of SO2 increases airway inflammation, apparently by inducing an increase in the expression of GM-CSF and IL-8.
