The Age-at-Onset of Leprosy

The Age-at-onset of Leprosy.

On the Age of Leprosy

Leprosy is a chronic infection of the skin and nerves caused by Mycobacterium leprae and the newly discovered Mycobacterium lepromatosis. Human leprosy has been documented for millennia in ancient cultures. Recent genomic studies of worldwide M. leprae strains have further traced it along global human dispersals during the past ∼ 100,000 years. Because leprosy bacilli are strictly intracellular...

Retinopathy of prematurity: age at onset.

The age at which retinopathy of prematurity was first seen was determined in 143 infants. In all, the initial ophthalmological examination was normal. Birth weights varied from 630 to 2700 g and gestational ages from 24.5 to 40.0 weeks. The median postnatal age at which acute retinopathy of prematurity was first seen was 51 and 40 days for those less than 28 and greater than or equal to 28 week...

Age at onset curves of retinitis pigmentosa.

OBJECTIVE To calculate age at onset curves of retinitis pigmentosa (RP) to resolve the difficulty in calculating the recurrence risk in a family. Retinitis pigmentosa is a common hereditary retinal disease that leads to blindness. It is a slow-onset disease, and family members of patients sometimes develop RP later. METHODS We studied 370 patients with typical RP. The age at onset was defined...

The Pfgc Equation of State at the Age of Fourteen

The purpose of this paper was to review and report the recent advances and progress that have been achieved on the fourteen year old PFGC equation of state. This paper will also discuss the good (pros) and the bad (cons) of this equation of state. Emphasis will be made on the following categories:A. Prediction of the pure component PVT properties1. Hydrocarbons in particular n-alkanes2. Selecte...
