RESUMEN
BACKGROUND: Job exposure matrices (JEMs) are epidemiological tools used to provide estimations of occupational exposures when it is not feasible to complete detailed individual occupational histories. AIMS: To identify and summarize the characteristics of published general population JEMs (GPJEM) of inhalable occupational exposures applied in studies of respiratory disease. METHODS: MEDLINE and EMBASE databases were searched using pre-defined search terms, with screening performed by two independent reviewers to identify studies reporting the use of a GPJEM. JEM creation papers were subsequently identified and reviewed for each individual GPJEM, noting its characteristics in terms of occupational classification system and exposure estimates. RESULTS: From 728 studies identified in initial searches, 33 GPJEMs of inhalable occupational exposures were identified. Versions of the International Standards Classification of Occupations were the most used occupational classification system. Binary, probability and intensity-based exposure estimates were most frequently reported in GPJEMs. CONCLUSIONS: Selection of a GPJEM to apply in epidemiological research should be based on the exposure(s) of interest, time period of occupations under review, geographical region for intended use, occupation classification system used and the exposure estimate outcome.

Behçet's disease is a chronic, relapsing, systemic inflammatory disease affecting the orogenital mucosa, eyes, joints, blood vessels, nervous system and intestines. The prevalence of neurological involvement varies geographically and can include psychiatric manifestations. Current evidence for a causal association between Behçet's disease and bipolar disorder is limited to a small number of case reports. We report a case of a patient with a recent diagnosis of bipolar disorder who was subsequently diagnosed with Behçet's disease. The 38-year-old male presented with a 6-month history of right eye visual blurring, 5-month history of mouth ulcers and 3 months of genital ulceration. His inflammatory markers were raised. An MRI of the brain was conducted in the absence of any focal neurological signs or symptoms owing to his past psychiatric history. The MRI showed changes in the medial aspect of the right temporal lobe highly suspicious of neuro-Behçet's disease. His inpatient care was coordinated with neurology, rheumatology, ophthalmology and psychiatry teams, and he was later discharged with outpatient follow up owing to a clinical improvement on high-dose steroids. This case shows that, although widely unrecognised, neuro-Behçet's can occur in the absence of focal neurology. Additionally, neuro-Behçet's should be considered in patients with bipolar disorder presenting with symptoms suggestive of Behçet's disease. The case emphasises how patients presenting with ulceration, mood disorder and visual changes should not have these symptoms considered in isolation and multisystem disease should be considered. Furthermore, the coordinated multidisciplinary approach required for the care of patients with Behçet's disease is demonstrated.

A diagnosis of asbestosis, which is a long-latency, fibrotic lung disease, has implications for the patient in terms of prognosis, treatment and compensation. Identifying and quantifying asbestos exposure is difficult without a detailed occupational history, and the threshold dose of asbestos required to cause asbestosis is not well understood. We reviewed all cases of asbestosis diagnosed between 2001 and 2016 at the Birmingham Regional NHS Occupational Lung Disease Service to determine the industries and occupations most frequently implicated in causation, in order to help clinicians identify where asbestosis might enter the differential diagnosis for a patient with chronic respiratory symptoms. A variety of construction trades were frequently reported including carpenters and joiners, pipe fitters, laggers, labourers, painters and shop fitters. Traditionally heavily exposed occupations such as shipbuilding were not commonly seen.

OBJECTIVES: The risk of developing active TB is greater in those receiving haemodialysis. This study aimed to describe the incidence of active tuberculosis among patients referred for management of kidney disease and dialysis in a high incidence UK city, with the purpose of informing latent TB testing and treatment practice. METHODS: Information from the tuberculosis register was cross-referenced with the Department of Renal Medicine patient information system. All patients seen between 1st January 2005 and 1st October 2016 were included in the analyses with the exception of those with prior TB. RESULTS: 68 cases of active TB were identified, an incidence of 126/100,000 patient-years (95% CI 97-169). Incidence was lowest in those with CKD 1 or 2 and rose as high as 256/100,000 patient-years (95% CI 183-374) in those receiving renal replacement therapy. 48% of cases were pulmonary and 87% of TB patients gave their ethnicity as either black/black British or Asian/Asian British, significantly more than in the non-TB renal group. Cases occurred steadily over the time period in which patients were in the cohort. CONCLUSION: TB incidence was very high among those receiving renal replacement therapy or CKD 4 or 5. Most cases occurred in those of an Asian/Asian British or black/black British background. Testing and treating such patients for latent TB is justified and should include those who have been receiving renal replacement therapy for some years.
