Background: Few studies have evaluated the association between preexisting vitamin D deficiency and incident tuberculosis (TB). We assessed the impact of baseline vitamins D levels on TB disease risk.
Methods and Findings: We assessed the association between baseline vitamin D and incident TB in a prospective cohort of 6,751 HIV-negative household contacts of TB patients enrolled between September 1, 2009, and August 29, 2012, in Lima, Peru. We screened for TB disease at 2, 6, and 12 months after enrollment. We defined cases as household contacts who developed TB disease at least 15 days after enrollment of the index patient. …

We report a case of a 16-year-old female who presented with bleeding diathesis. Peripheral blood film examination was consistent with microangiopathic hemolytic anemia with 7% fragmented red blood cells. The ADAMTS13 level was 40 ng/ml (reference range: 630-850 ng/ml). She responded to plasma exchange therapy and methylprednisolone and was discharged in a stable condition.

Orthokeratinized Odontogenic Cyst (Ooc): Clinicopathological And Radiological Features Of A Series Of 10 Cases, Nasir Ud Din, Maha Zubair, Jamshid Abdul-Ghafar, Zia Ullah Khan, Zubair Ahmad

Department of Pathology and Laboratory Medicine

Background: Orthokeratinized Odontogenic Cyst (OOC) is a rare, developmental odontogenic cyst which was considered in the past to be a variant of Odontogenic keratocyst (OKC) later renamed as keratocystic odontogenic tumor (KCOT). The treatment of OOC is by enucleation and the prognosis, following enucleation is excellent with a recurrence rate of less than 2%. On the other hand, OKC has a recurrence rate between 8 and 25% after enucleation. Thus it is important to differentiate between the two entities.
Methods: All cases reported in our section as OOC during the period 2013 to 2018 were retrieved from the surgical pathology …
