Our results show a significant accumulation of lead in bone tissue in persons who have died of CKDu which indicates a higher chronic exposure of the CKDu victims, to lead. Fluoride content in the bones of cases is also significantly high. The results indicate that a gradual reduction of glomerular filtration rate (GFR) may have occurred with the chronic exposure to lead. At a certain point of the threshold of low GFR, excretion of fluoride may be impaired, since the main excretory pathway of fluoride is via the kidneys. Fluoride accumulation in blood in turn may exacerbate nephrotoxicity, triggering a synergistic cascade of events which may lead to a further deterioration in the GFR. The extremely high fluoride content detected suggests a cumulative effect in people exposed to comparatively higher fluoride levels, most probably from drinking water.
Tuberculosis (TB)-related stigma presents a major barrier to care of persons with TB through its impact on treatment initiation and retention in care. This is particularly challenging in settings with high prevalence of both TB and HIV where fear of HIV/AIDS can amplify stigma surrounding TB. The purpose of this study was to validate a TB stigma scale for use among persons presenting for outpatient HIV screening in the Umlazi township of South Africa and evaluate factors associated with TB-related stigma in this high HIV burden setting.
In this cross-sectional study, we measured TB-related stigma in adults prior to HIV testing using a 12-item scale designed to assess experienced and felt TB-related stigma.
Among 848 adults, mean age was 32 years, 54% were male, and the median TB stigma score was 19 of 36 (interquartile range 15-23). We identified two factors in the stigma scale which had excellent reliability (Cronbach's alpha 0.85, 0.89). Persons with high TB stigma were more likely to be male (adjusted relative risk ratio [aRRR] 1.56, 95% confidence interval [CI] 1.11-2.28) and have accurate knowledge of TB transmission (aRRR 1.90, 95% CI 1.16-3.10) as compared to those with low stigma. Variables not significantly associated with stigma in the multivariate model included education, income, prior TB or HIV diagnoses, and depression.
Male sex and TB knowledge were associated with higher TB stigma in an outpatient HIV clinic in a South African township. Identifying risk factors associated with stigma will be important to guide stigma reduction interventions.

Trigeminal neuralgia (TN) is considered one of the most painful illnesses known to medical practice. Little is known about TN in Ethiopia. Our study aimed to assess clinical characteristics, treatment, and associated factors of TN.
A cross-sectional study was conducted on a total of 61 patients with confirmed Trigeminal neuralgia visiting outpatient neurology clinics of two government teaching Hospitals and two private health facilities in Addis Ababa, Ethiopia between June 2019 and March 2020.
Our participants' age range between 21 and 78 years with mean ± SD age of 50.7 ± 14.2 years. Males accounted for 50.8%. Twenty-five (41%) reported a prior history of one or more tooth extraction on the painful side. In the majority (68.9%) of the patient's right side of the face was affected. The mandibular nerve was the commonly involved branch (47.5%). Fifty-five (90.2%) of patients fulfilled criteria for classical TN and 9.8% had symptomatic TN. Novobiocin mouse The majority of the participants reported mixed types of pain sucction among our patients, hinting at the scale of miss and delayed-diagnoses. Thus, we recommend conducting a well-designed prospective study to support our findings.
The majority of our patients had Classical TN in the mandibular nerve distribution on the right side of the face and well satisfied with carbamazepine only treatment. Furthermore, we observed a higher proportion of dental extraction among our patients, hinting at the scale of miss and delayed-diagnoses. Thus, we recommend conducting a well-designed prospective study to support our findings.
There are multiple obstacles encountered by immigrants attempting to engage hepatitis C virus (HCV) care and treatment. We evaluated the diversity and treatment outcomes of HCV-infected immigrants evaluated for Direct Acting Antiviral (DAA) therapy in Canada.
The Canadian Network Undertaking against Hepatitis C (CANUHC) Cohort contains demographic information and DAA treatment information prospectively collected at 10 Canadian sites. Information on country of origin and race are collected. Characteristics and outcomes (sustained virological response; SVR) were compared by immigration status and race.
Between January 2016 and May 2018, 725 HCV-infected patients assessed for DAA therapy were enrolled in CANUHC (mean age 52.66 ± 12.68 years); 65.66% male; 82.08% White, 5.28% Indigenous, 4.64% South East Asian, 4.64% East Indian, 3.36% Black). 18.48% were born outside of Canada. Mean age was similar [immigrants 54.36 ± 13.95 years), Canadian-born 52.27 ± 12.35 years); (p = 0.085)]. The overall baseline fibrosis score (in kPa measured by transient elastography) was similar among Canadian and foreign-born patients. Fibrosis score was not predicted by race or genotype. The proportion initiating DAA therapy was similar by immigrant status (56.72% vs 49.92%). SVR rates by intent-to-treat analysis were similar (immigrants-89.47%, Canadian-born-92.52%; p = 0.575).
A diverse immigrant population is engaging care in Canada, initiating HCV antiviral therapy in an equitable fashion and achieving SVR proportions similar to Canada-born patients. Our Canadian experience may be of value in informing HCV elimination efforts in economically developed regions.
