Seasonal variation in tuberculosis diagnoses recently has been reported in various populations. In Australia, seasonality of tuberculosis diagnoses was more pronounced in areas where UV exposure is reduced and vitamin D deficiency is more prevalent. Our findings suggest vitamin D deficiency as a factor in disease activation.

STUDY DESIGN Initial assessment involved 360 patients (90% women and 10% men) attending spinal and internal medicine clinics over a 6-year period who had experienced low back pain that had no obvious cause for more than 6 months. The patients ranged in age from 15 to 52 years. OBJECTIVES To investigate the contribution of vitamin D deficiency as a cause for idiopathic chronic low back pain, t...

RATIONALE Vitamin D deficiency has been implicated as a pathogenic factor in sepsis and intensive therapy unit mortality but has not been assessed as a risk factor for acute respiratory distress syndrome (ARDS). Causality of these associations has never been demonstrated. OBJECTIVES To determine if ARDS is associated with vitamin D deficiency in a clinical setting and to determine if vitamin ...

Objective: Rickets due to vitamin D deficiency is an important cause of the infantile hypocalcemia, but congenital rickets is not so common. Vitamin D deficiency may present with hypocalcemia and sometimes with hyperphosphatemia because of the inadequate response of parathyroid hormone to hypocalcemia during early infancy. We report a case of congenital rickets due to maternal vitamin D deficie...

In this study, the aim was to determine whether adding vitamin D to the standard therapeutic regimen of schizophrenic male patients with inadequate vitamin D status could improve some aspects of the symptom burden or not. This study was an open parallel label randomized clinical trial. Eighty patients with chronic stable schizophrenia with residual symptoms and Vitamin D deficiency were recruit...

BACKGROUND Vitamin D deficiency and insufficiency are prevalent worldwide, but relatively few studies have examined vitamin D status in working populations. AIMS To assess the prevalence of vitamin D deficiency and insufficiency in Canadian workers and investigate risk factors in this population. METHODS A cross-sectional study using data from a health programme enrolling workers mostly fro...

Vitamin D deficiency is a preventable health problem. Vitamin D deficiency among pregnant women is frequent in many populations over the world. Research indicates that adequate vitamin D intake in pregnancy is optimal for maternal, fetal and child health. Adverse health outcomes during pregnancy are preeclampsia; gestational diabetes mellitus and caesarean section. Consequences in newborns are ...
