RESUMO

BACKGROUND: There is concern that the values provided by devices using infrared thermometry in emergency departments (EDs) do not reflect body core temperature accurately. OBJECTIVES: Evaluation of three thermometers commonly used in the ED. METHODS: Two infrared ear thermometers and an infrared forehead thermometer were evaluated using 1) the Voltcraft IRS-350 calibration device, 2) comparing temperature values to a rectal end-exercise temperature (T-RECT) of 38.1°C in 12 participants, and 3) comparing temperature values to rectal temperature in 133 ED patients. RESULTS: Calibration across the human core temperature range revealed that the ear thermometers underestimated radiant temperature by 0.77 ± 0.39°C and 1.84 ± 0.26°C, respectively, whereas the forehead thermometer overestimated radiant temperature by 0.90 ± 0.51°C. After cycling exercise, all thermometers underestimated T-RECT (0.54 ± 0.27°C and 1.03 ± 0.48°C for the ear thermometers and 1.14 ± 0.38°C for the forehead thermometer). In the ED, the ear thermometers underestimated T-RECT by 0.31 ± 0.37°C and 0.46 ± 0.50°C, whereas the forehead thermometer exhibited a nonsignificant overestimation of 0.04 ± 0.46°C. If the threshold for fever in all systems had been set to 37.5°C instead of 38.0°C, the sensitivity and specificity of the systems for real fever (T-RECT ≥ 38°C) are, respectively, 71% and 96% (ear thermometer 1), 57% and 97% (ear thermometer 2), and 86% and 90% (forehead thermometer). CONCLUSION: We conclude that the investigated thermometers are not reliable as devices to measure radiant temperature, cannot be used to assess body core temperature during exercise, but may be used as a screening device, with 37.5°C as a threshold for fever in emergency care settings.

RESUMO

Bardet-Biedl syndrome (BBS) is a rare autosomal recessive disorder of the cilia, often resulting in a phenotype of obesity, rod-cone dystrophy, a variable degree of intellectual disability, polydactyly, renal problems, and/or hypogonadism in males or genital abnormalities in females. We here report the case of an 11-year-old girl who presented with postaxial polydactyly, retinal dystrophy, and childhood obesity, suggesting Bardet-Biedl syndrome. She had no renal problems, developmental delay, or intellectual disability. Genetic testing revealed compound heterozygous variants in the IFT74 gene (c.371_372del p.Gln124Argfs*9 and c.16850-1G>T p.?). We here report the second patient with Bardet-Biedl syndrome due to biallelic IFT74 variants. Both patients have obesity, polydactyly, retinal dystrophy, and no renal abnormalities. The present case however, has normal intellect, whereas the other patient has intellectual disability. We hereby confirm IFT74 as a BBS gene and encourage diagnostic genetic testing laboratories to add IFT74 to their BBS gene panels.

RESUMO

BACKGROUND: South Africa (SA) has one of the world's largest HIV treatment programmes, to which a dramatic increase in life expectancy has been attributed. However, there continue to be concerns regarding the reporting of HIV-related mortality in SA, which varies by source. As accurate HIV mortality estimates are key to measuring the success of the national programme as well as identifying areas for improvement, we propose a complementary approach to monitoring changes in HIV-related mortality using routine inpatient records to examine trends in causes of death and HIV status over time. OBJECTIVES: To investigate the feasibility of this approach by calculating mortality due to natural causes in the medical ward of a hospital during 2010 by HIV status. METHODS: We conducted a cross-sectional study of inpatient mortality at a regional hospital in Johannesburg, SA, analysing all deaths due to natural causes among adult medical ward inpatients. Cause of death was recorded from the mortuary register. HIV status was ascertained directly from the mortuary register or from laboratory tests specific for HIV diagnosis or monitoring. RESULTS: Of 1 167 inpatients who died, the majority were HIV-positive (58%). HIV positivity among males (55%) was slightly lower than that among females (61%), and HIV-positive patients were younger (median 40 years) than those who were HIV-negative (56 years) and of unknown HIV status (68 years). 'Infections and parasites' was the most common cause of natural death (29%). On average, HIV-positive patients were admitted for slightly longer (mean 10.5 days) than HIV-negative patients (9.6 days) and those of unknown HIV status (8.9 days), yet HIV-positive inpatient deaths accounted for the majority (62%) of the total bed days. CONCLUSIONS: Even with widespread access to antiretroviral therapy, the majority of inpatient natural deaths at a large public sector hospital in 2010 were of HIV-positive patients and were probably related to HIV. In view of the importance of accurate data on causes of death, both for the HIV programme and to track other diseases, large-scale expansion of this approach over a longer period should be considered.

RESUMO

SETTING: A hospital-based tuberculosis focal point (TBFP) at a tertiary hospital in Johannesburg, South Africa. OBJECTIVE: To describe the possible tasks and impact of a hospital-based TBFP as well as staffing and infrastructure requirements for setting up a hospital-based TBFP. ACTIVITIES: A TBFP can centralize the notification and referral of new TB cases, perform human immunodeficiency virus counseling and testing, assessment of difficult to diagnose TB suspects and management of complicated TB cases, and it can provide an ideal setting for research and health care worker training. RESULTS: The number of TB suspects assessed by sputum initially increased, followed by a decrease starting in 2010, which correlates with the globally decreasing TB incidence. The proportion of TB cases who failed to link to TB care decreased from 23% to 14% between 2009 and 2012. Almost 40% of cases with hepatotoxicity required an adjusted treatment regimen. Roll-out of Xpert(®) MTB/RIF testing and decentralized drug-resistant TB treatment increased the number of rifampicin monoresistant and sputum smear-negative multidrug-resistant TB cases treated on an out-patient basis. CONCLUSION: A hospital-based TBFP complements care at primary care level by coordinating TB care for a vulnerable population of patients diagnosed in a hospital setting, and by coordinating the diagnosis and treatment of complex TB cases.

RESUMO

Antiretroviral therapy has changed the face of the treatment of HIV throughout the world, converting a fatal into a chronic disease. HIV has reached disastrous levels of infection in southern Africa, and increased use of life-saving therapy is being implemented. The antiretrovirals have a variety of metabolic side effects that have been implicated in cardiovascular disease in other populations. This article discusses the impact of HIV on southern Africa, the metabolic and cardiac complications of both HIV and antiretrovirals, and strategies for dealing with drug side effects.
