intraductal papillary mucinous neoplasms (ipmns) are rare pancreatic tumours, accounting for less of 1-2% of all neoplasms of the gland. main characteristics of ipmns are their favourable prognosis as these pre-malignant or frankly malignant lesions are usually slow-growing tumours and radical surgery is frequently possible. according with the localization of the lesions, three different entiti...

The MTT method for rifampicin and isoniazid susceptibility testing of Mycobacterium tuberculosis was developed by using bacterial suspension prepared from colonies on solid media. The MTT tube assay in 1 ml Middlebrook 7H9 broth was completed within 4 days for rifampicin (RMP) and within 7 days for isoniazid (INH). When MTT assay results with 279 M. tuberculosis clinical isolates were compared ...

An 82-year-old female patient presented with a large perianal hyperkeratotic tumor extending into the anal canal. Staging did not reveal any metastatic spread. Diagnosis of verrucous carcinoma or Buschke-Löwenstein tumor, respectively, was based on typical clinical and histologic features. Moreover, human papillomavirus 6b DNA sequences could be detected by PCR. Surgical excision could not be p...

A total of 120 mycobacterial isolates were recovered from 1,068 clinical specimens. Of these, 82.5% were in MGIT 960, 83.3% were in MB/BacT, 80% were in BACTEC 460, and 70% were on Löwenstein-Jensen medium. Mean times to detection of Mycobacterium tuberculosis (n = 96) were significantly shorter with MGIT 960 (12.6 days, P = 0.003) and BACTEC 460 (11.8 days, P < 0.001) than with MB/BacT (15.9 d...

ISSN 0001-5555 Condylomata acuminata (CA) are sexually transmitted benign warty lesions that usually affect the anogenital epithelium. Low-risk human papillomavirus (HPV) infection, such as HPV type 6 or 11, is associated with the disease (1). These lesions exhibit a small papular, filiform or ...

UNLABELLED Tumours can metastasize to sites of other tumours but this is a rare event. The phenomenon has been well described in primary tumours of the lung and breast. This has been described in melanomas but as very rare occurrence. We describe a case of a malignant melanoma that metastasized to a pre-existing meningioma. We have tried to highlight this phenomenon in patient with melanoma and...

The purpose of the present study was to evaluate the usefulness of rpoB-PCR assay and concentration flurochrome (CF) staining against culture for direct detection of mycobacteria sp in respiratory specimen amongsymptomatic patients. Of the 900 specimens 52 were culture positive with Löwenstein-Jensen Medium (LJM). Of the 52 culture positive samples, 48 were positive by rpoB-PCR (sensitivity 92....

We evaluated a new mycobacterial culture system, MB Redox, for recovery rate and time to detection of mycobacteria from 742 consecutive respiratory specimens and compared the results to those found with Löwenstein-Jensen (LJ) medium. Twenty specimens (2.7%) were positive for M. tuberculosis: 17 on LJ medium and 19 in MB Redox, with 16 specimens positive in both media. In addition, 24 specimens ...
