“BACKGROUND: Existing international guidelines provide different recommendations for the management of contacts of multidrug-resistant tuberculosis (MDR-TB) patients.

OBJECTIVE: To conduct two systematic reviews with the aim of identifying chemoprophylactic

approaches that are effective in contacts of MDR-TB patients to assist in policy making.

DESIGN: We systematically searched the Medline, Embase, Central, LILACS, TRIP and BIOSIS Preview databases for studies on the effectiveness of anti-tuberculosis drugs in preventing active TB in persons at risk of developing MDR-TB. This was done as an update of a systematic review from 2006 using the same methodology. In addition, we searched for studies including persons at risk of developing TB after exposure to non-MDR-TB patients

who were treated with anti-tuberculosis Belnacasan inhibitor drugs other than isoniazid or rifampicin.

RESULTS: Of 1195 references assessed in the update, one additional study could be included. As the initial review included two studies, the total number of included studies equals three. One study reported no contacts who developed TB, whether or not they received prophylaxis. The other two studies showed non-significant risk differences of 4% (95%CI -3 to 12), and 5% (95%CI -2 to 11), BI-D1870 purchase both in favour of chemoprophylaxis. For the additional review, 2480 references were assessed, but none could be included.

CONCLUSION: The attention given to MDR-TB in recent years has not resulted in publications on preventive treatment for contacts of MDR-TB patients. The

available evidence is not sufficient to support or reject preventive treatment. Furthermore, the combined available evidence is of very low quality.”
“Sialoblastoma is a rare tumor of the salivary gland that commonly occurs in the parotid gland and occasionally in the sub-mandibular gland. The malignant potential of sialoblastoma has been documented in only 3 of 32 cases of sialoblastoma reported thus far. In the last 15 years, we have encountered 2 cases of sialoblastoma, in a newborn and in a 15-year-old boy, both arising within the parotid gland. Case 1 has been previously reported and although there were 2 recurrences, at 1 and 9 years post resection, it has shown benign biological behavior. Case 2 is unusual since the patient presented with metastases. We reviewed the 2 cases, including the 2 recurrences from the first case, for histologic and immunohistochemical differences. Although both cases showed similar cytomorphologic features, there was a significant difference in Ki-67 expression: 20% in case 1 (original tumor), <2% in case 1 (recurrent tumor), and nearly 70-80% in the recent malignant case. The difference is remarkable when combined with p53 expression, which was focally positive in the first case but diffusely positive in the second.
