Benign osteoblastoma (OB) is a rare tumor of bone representing less than 1% of all tumors of the maxillofacial region. Vertebral column, sacrum, long bones, and calvarium are more frequent sites of this tumor. Clinically, patients present with pain and swelling. Histologically, contain a well vascularized, osteoblastic connective tissue stroma and occasionally, osteoclasts along with osteoid and varying degrees of calcification, as well as immature bone may also be noted. The main aim of this report is present a case of OB occurring in the mandible and a brief review of English Medical Literature of this tumor. Many bone-producing lesions possess some overlapping clinical, radiographic or histopathological findings similar to osteoblastoma. Understanding and correlating all features helps in correct diagnosis and adequate management of this rare entity. Hence, osteoblastoma has to be differentiated from other bone lesions for correct diagnosis.

Pioglitazone may be a new alternative for use in women with PCOS, providing more metabolic and reproductive benefits and possibly protection from developing diabetes and cardiovascular problem.

Background Colorectal cancer often presents with obstruction needing urgent, potentially life-saving decompression. The comparative efficacy and safety of endoluminal stenting versus emergency surgery as initial treatment for such patients is uncertain. Methods Patients with left-sided colonic obstruction and radiological features of carcinoma were randomized to endoluminal stenting using a combined endoscopic/fluoroscopic technique followed by elective surgery 1–4 weeks later, or surgical decompression with or without tumour resection. Treatment allocation was via a central randomization service using a minimization procedure stratified by curative intent, primary tumour site, and severity score (Acute Physiology And Chronic Health Evaluation). Co-primary outcome measures were duration of hospital stay and 30-day mortality. Secondary outcomes were stoma formation, stenting completion and complication rates, perioperative morbidity, 6-month survival, 3-year recurrence, resource use, adherence to chemotherapy, and quality of life. Analyses were undertaken by intention to treat. Results Between 23 April 2009 and 22 December 2014, 245 patients from 39 hospitals were randomized. Stenting was attempted in 119 of 123 allocated patients (96.7 per cent), achieving relief of obstruction in 98 of 119 (82.4 per cent). For the 89 per cent treated with curative intent, there were no significant differences in 30-day postoperative mortality (3.6 per cent (4 of 110) versus 5.6 per cent (6 of 107); P = 0.48), or duration of hospital stay (median 19 (i.q.r. 11–34) versus 18 (10–28) days; P = 0.94) between stenting followed by delayed elective surgery and emergency surgery. Among patients undergoing potentially curative treatment, stoma formation occurred less frequently in those allocated to stenting than those allocated to immediate surgery (47 of 99 (47.5 per cent) versus 72 of 106 (67.9 per cent); P = 0.003). There were no significant differences in perioperative morbidity, critical care use, quality of life, 3-year recurrence or mortality between treatment groups. Conclusion Stenting as a bridge to surgery reduces stoma formation without detrimental effects. Registration number: ISRCTN13846816 (http://www.controlled-trials.com).

Varicella zoster virus (VZV) is a member of Herpesviridae family. It can cause two distinct clinical entities: varicella (chickenpox) and herpes zoster (shingles).1,2Herpes Zoster(HZ) is painful, vesicular rash in a limited area on one side of body due to the reactivation of latent VZV in dorsal root ganglia.Involvement of three or more dermatomes is known as disseminated zoster and seen in immunocompromised individuals.It can occur at any age. The risk of herpes zoster increases with old age and in patients with reduced cell mediated immunity such as haematological malignancies, immunosuppressive therapies, HIV infection and transplant recipients. The incidence of herpes zoster has been variably reported as 2% in Chronic myeloid leukaemia (CML), 13% in Chronic lymphocytic leukemia(CLL) and 30% in transplantrecipients.3-5This was a rare case of disseminated herpes zoster in a patient with Acute Lymphoblastic Leukaemiadeveloped while on chemotherapy progressing to prolonged myelosuppression.Bangladesh Med Res Counc Bull 2018; 44(1):59-61

Lead exposure was assessed in a random cohort of 70 male papier mâché workers and compared with 35 age and sex matched controls. Blood lead levels in workers were significantly higher than in controls (Mean 68.07 ± 44.64 ug/dl vs 25.52 ± 16.56 ug/dl respectively; P < 0.001). Urinary lead was also higher in workers (128.53 ± 52.61 ug/l) compared to controls (91.18 ± 27.06, P < 0.001), but excretion of urinary coproporphyrin in the two groups was not significantly different (102.78 ± 153.42 vs 70.03 ± 27.06 ug/l, P > 0.05). Blood levels bore a significant correlation with age but did not bear any correlation with the duration of exposure. Various modes of exposure to lead included hand mixing of paints, skin application of the paint to match shades and making point of the brush using lips and the tongue.
