PURPOSE: Live Mycobacterium bovis Bacille Calmette-Guerin (BCG) has a suppressive effect on asthma, but its use in clinical practice may be limited due to adverse reactions. To develop a product that is effective for suppressing asthma with minimal adverse reactions, we investigated whether the heat-killed body or culture supernatants of mycobacteria could also prevent asthma development. METHODS: Female BALB/c mice were treated with live BCG, the heat-killed body, or culture supernatants of BCG or Mycobacterium tuberculosis intraperitoneally, while sensitizing and provoking with ovalbumin. Then they underwent a methacholine bronchoprovocation test, and the peribronchial inflammatory cell numbers and cytokine levels in splenocyte culture supernatants were assessed. RESULTS: The airway sensitivity to methacholine decreased significantly after treatment with not only live BCG (30.8 versus 10.0 mg/mL, P<0.001) but also with the culture supernatant (BCG, 23.0 mg/mL, P<0.05; M. tuberculosis, 20.5 mg/mL, P<0.05). In contrast, heat-killed mycobacteria did not effectively decrease airway sensitivity. The peribronchial eosinophil counts and the goblet cell proportions in total epithelial cells decreased significantly in most of the groups. The interferon-gamma/interleukin-5 ratios increased significantly in most of the treatment groups except for the heat-killed groups, and were significantly related to airway sensitivity (r=0.312, P<0.01) and peribronchial eosinophil counts (r=-0.416, P<0.001). Interleukin-17A level was inversely related to airway sensitivity (r=-0.212, P<0.05) and was significantly lower in the live BCG group than in the control (137+/-20 versus 308+/-57 pg/mL, P<0.05). CONCLUSIONS: BCG and mycobacteria culture supernatants may effectively prevent the development of asthma associated with altered Th1/Th2 cytokines and interleukin-17A levels.

BACKGROUND: The anaphase promoting complex (APC) promotes the degradation of mitotic cyclins as well as other substrates involved in sister chromatid adhesion. This study was carried out to examine the relationship between the APC expression and the clinicopathological variables, in an attempt to determine the role of the APC in the proliferation of lung cancer and to evaluate the possibility of an aberrant APC function in surgically resected squamous cell carcinomas and adenocarcinomas of the lung. METHODS: Immunohistochemical staining was performed for APC, Ki-67, cyclin B1, Cdc2, MMP-2 and VEGF in 55 cases of squamous cell carcinoma and 34 cases of adenocarcinoma of the lung, using the avidin-biotin-peroxidase method. RESULTS: The immunohistochemical stains for APC revealed a positive reaction in 49 cases (55.1%). The APC expression level was higher in the cyclin B1-positive group (p= 0.01), the Cdc2-positive group (p=0.001), the MMP-2-positive group (p=0.03), the group with lymph node metastasis (61.4% vs 48.9%), and the group with stage II/III cancer (60.7%) compared with those with stage I (42.9%). CONCLUSIONS: The APC may have an aberrant function, such as a change in its role in controlling the cell cycle, and might be associated with the invasiveness and proliferation of tumor cells.

To investigate the underlying mechanisms of C18 fatty acids (stearic acid, oleic acid, linoleic acid and alpha-linolenic acid) on mast cells, we measured the effect of C18 fatty acids on intracellular Ca2+ mobilization and histamine release in RBL-2H3 mast cells. Stearic acid rapidly increased initial peak of intracellular Ca2+ mobilization, whereas linoleic acid and alpha-linolenic acid gradually increased this mobilization. In the absence of extracellular Ca2+, stearic acid (100 microM) did not cause any increase of intracellular Ca2+ mobilization. Both linoleic acid and alpha-linolenic acid increased intracellular Ca2+ mobilization, but the increase was smaller than that in the presence of extracellular Ca2+. These results suggest that C18 fatty acid-induced intracellular Ca2+ mobilization is mainly dependent on extracellular Ca2+ influx. Verapamil dose-dependently inhibited stearic acid-induced intracellular Ca2+ mobilization, but did not affect both linoleic acid and alpha-linolenic acid-induced intracellular Ca2+ mobilization. These data suggest that the underlying mechanism of stearic acid, linoleic acid and alpha-linolenic acid on intracellular Ca2+ mobilization may differ. Linoleic acid and alpha-linolenic acid significantly increased histamine release. Linoleic acid (C18:2: omega-6)-induced intracellular Ca2+ mobilization and histamine release were more prominent than alpha-linolenic acid (C18:3: omega-3). These data support the view that the intake of more alpha-linolenic acid than linoleic acid is useful in preventing inflammation.

Gastrocolocutaneous fistula is a rare complication of the percutaneous endoscopic gastrostomy (PEG) procedure. Typical symptoms usually occur in the first few months. We recently encountered 2 patients with 8- and 33-month asymptomatic periods. A 74-year-old man presented with watery diarrhea for 1 month. He had undergone PEG 9 months earlier. During workup, an upper endoscopy and abdominal CT scan revealed the migration of the feeding tube into the transverse colon. He was discharged with a nasogastric tube after treatment. A 77-year-old man presented with sudden loosening of his PEG tube with a duration over 3 days. He had undergone PEG procedure three times until that time. During workup, a gastrocolocutaneous fistula was diagnosed. However, when previous studies were reviewed, an abdominal CT scan, which was done 6 months ago before the third PEG, showed the fistula already existed at that time, suggesting that it was created about 33 months earlier when he underwent the second PEG procedure. The patient died of pneumonia aggravation despite conservative treatment. Both a high index of suspicion and the careful inspection of the upper endoscopy are very important for early diagnosis regardless of symptoms.

Intravesical bacillus Calmette-Guérin (BCG) immunotherapy is a common treatment modality for bladder cancer after transurethral resection of a bladder tumor. This therapy is generally safe, and development of a prostatic abscess with a prostatorectal fistula after intravesical BCG immunotherapy is a very rare complication. This finding was incidentally obtained by the authors, who examined a patient with colonoscopy for evaluation of abdominal pain. The patient was successfully treated with antitubercular drugs. To the authors’ knowledge, this is the first report of a patient with a tuberculous prostatic abscess with prostatorectal fistula after BCG immunotherapy in South Korea.

OBJECTIVES: While a severe to profound sudden sensorineural hearing loss (SSNHL) may cause serious disability in verbal communication, there have been little studies focusing on this high degree SSNHL. The present study was aimed to investigate the characteristics of hearing recovery in a high degree SSNHL (>70 dB). METHODS: Three hundred and two SSNHL patients were enrolled. For a long-term follow-up, 46 patients were evaluated. Hearing level was examined by pure tone audiometry on day 1, week 3, month 3, month 6, and year 1 or after. According to the degree of the initial hearing loss, the patients were divided into 4 groups from 70 to > or =100 dB. RESULTS: After 3 weeks, the recovery rate and mean hearing gain was 61%, 23.85 dB in the 70 dB group, whereas 10%, 6.61 dB in the > or =100 dB group. There was a significant correlation between 3-week recovery and final hearing outcome. However, there was almost no recovery after 3 months. CONCLUSION: An early recovery can be a prognostic factor for the final recovery in severe to profound SSNHL. Since recovery after 3 months is rare, an early hearing intervention like hearing aid or cochlear implantation should be considered in the high degree SSNHL to restore the patient's verbal communication.

PURPOSE: We sought to evaluate the distribution and characteristics of meibomian gland dysfunction (MGD) and the treatment patterns for symptomatic MGD patients in South Korea. METHODS: One hundred ninety-six right eyes of 196 MGD patients were enrolled. For each patient, meibum expressibility in the central eight glands in both the upper and lower eyelids was examined. Each upper and lower eyelid was separately classified into one of the following three subtypes: nonobvious obstructive (low-delivery without lid margin abnormality), obvious obstructive (low-delivery with lid margin abnormality), and hypersecretory (high-delivery with lid margin abnormality). All treatment plans were also recorded. RESULTS: The mean number of expressible glands of the central eight glands in the upper eyelids (3.9 ± 2.6) was significantly higher than that in the lower eyelids (2.2 ± 2.4, p < 0.001). Obvious obstructive MGD was the most common subtype, followed by the hypersecretory and nonobvious obstructive subtypes in both the upper and lower eyelids. Of the 196 subjects, 38 (19.4%) had upper and lower eyelids that were assigned to different categories. Eyelid hygiene was the most prescribed treatment (74.5%), followed by lubricant eye drop usage (71.5%). Physicians tended to determine treatment plans based on the subtype of the upper eyelid rather than that of the lower eyelid. CONCLUSIONS: The majority of subjects were classified as having the obvious obstructive subtype of MGD, and 19.4% had upper and lower eyelids that were different subtypes. Eyelid hygiene was the most prescribed treatment for MGD patients, and treatment patterns were mostly determined based on the subtype of the upper eyelids.

Hyperplastic polyps are often multiple and by far the most frequent lesions among gastric polyps, contributing for about 90% of the polypoid lesions observed in the stomach. However, hyperplastic gastric polyposis is rare and was not exactly evaluated for natural course. These lesions are considered reactive and not genetically determined conditions. So it has been claimed that the hyperplastic polyps and hyperplastic polyposis are non-neoplastic lesions that result from regenerative hyperplastic reaction to inflammation and erosion. Recently we experienced a hyperplastic gastric polyposis with morphological changes during short follow-up period and reported herein.
