Heavy metals are a major environmental threat in India and there are several health risks associated with it. The aim of this study was to investigate the relationship between the blood levels of lead, cadmium, arsenic, and mercury and a sensoneurial hearing loss in children aged one to ten years.

Heavy metal blood levels were determined using inductively coupled plasma mass spectrometry, with appropriate quality control.

We found significantly higher blood lead concentration (mg/L; Mean ± SE) in children with a hearing loss (53.2 ± 4.4) compared to healthy controls (38.4 ± 4.7)/P = 0 0.03/.

Children's blood lead levels ≥ 50 mg/L compared to the levels < 10 mg/L were associated with increased probability of hearing loss (OR, 48.8; 95% CI, 41.9-55.6). The differences in the blood levels of cadmium, arsenic, and mercury between the children with a hearing loss and controls were statistically insignificant (P > 0.05).

Powered surgical instruments use to cut bones and fashion them for joint implant produce noise. Prior studies have not analyzed direct in vivo measurements of multiple procedures and exposure time. This study evaluates actual surgical noise levels exposure to the surgeon and this cumulative exposure that can result in noise-induced hearing loss (NIHL).

Prior studies evaluated short duration noise exposure to surgical equipment in vitro, or in an operating room environment.

This study evaluated in vivo cumulative measurements over an entire operating day and the associated risks.

Noise exposure to operating room personnel was measured during multiple knee replacement surgeries over three days. Measurements were compared to occupational exposure limits set by the National Institute for Occupational Safety and Health (NIOSH) and the Occupational Safety and Health Administration (OSHA).

Surgeons' noise exposures exceed noise occupational exposure limits. Recorded levels of 104 dBA did occur with levels of 85dBA found from 10-18% of the time.

Surgeons performing multiple total knee replacements per day are at risk of NIHL due to noise exposures that exceed National Institute for Occupational Safety and Health recommendations. Surgeons should be included in a hearing loss prevention program.

Dental fluorosis is an acquired defect of enamel due to the exposure of an individual to excessive fluoride levels during tooth development. It could result in mild-to-severe discoloration of teeth, which might necessitate esthetic correction. Bleaching is one of the common treatment modalities used in the esthetic correction of such cases. In-office power bleaching is one of the techniques of tooth bleaching that involves clinical application and activation of the bleaching agent with light to accelerate the bleaching process. BiPInducerX This case report describes the esthetic correction of severe dental fluorosis by power bleaching, without any need for invasive treatment. This report suggests that in-office power bleaching is an effective and conservative method for esthetic correction of tooth discoloration in severe dental fluorosis.Lupus panniculitis is usually difficult to treat, and the patient is often put on multiple immunosuppressives with variable clinical response and relapses, notwithstanding the long-term side effects. We describe two cases of refractory lupus panniculitis which have been treated successfully with rituximab which is a chimeric anti-CD20 antibody. It reduces the number of circulating mature B-cells, thereby reducing the autoantibodies and the mediators of inflammation. Rituximab is a good alternative to patients who are not responsive to conventional treatment options for lupus panniculitis. There have been few side effects reported by the patients, but the clinical response and psychological well-being clearly outweigh them.

Chronic lymphocytic leukemia (CLL) is a heterogeneous group of monoclonal forms of lymphoproliferative disorder, which is usually common among older adults. There is an increasing trend in the number of patients presenting with the disease.

This study aims to determine the epidemiology pattern of CLL in Cross River state.

A retrospective study with 10-years data (2010-2019) obtained from the register of the Department of Haematology and Blood Transfusion, University of Calabar Teaching Hospital, Calabar. The data collected include the date of presentation, the age, gender, location of residence, and occupations of the patients.

A total of 47 cases were seen during the 10-year period, with a male female ratio of 11. The mean age at presentation was 59 years. The majority of the patients were in their fifth and sixth decades of life. Most patients (44.68%) practice farming as their profession.

The study has reawaken our consciousness on the increasing trend on the epidemiological burden of CLL in our environment and will help to enhance further investigation into the relationship between the rising trend and available possible risk factors in our environment.

Rotavirus remains one of the main causative agents of gastroenteritis in young children. This happens, especially in countries (e.g., Nigeria) that have not yet introduced the vaccine into the national immunization program. A significant prevalence of Rotavirus infection both in children and adults without major symptoms has earlier been reported. This study aimed at defining the prevalence of asymptomatic Rotavirus infection from apparently healthy children in Maiduguri, Borno State, Northeastern Nigeria.

A total of 269 stool samples were randomly collected from apparently healthy children <15 years of age from July 2017 to June 2018. All samples were screened using a commercially available enzyme-linked immunosorbent assay kit for the presence of Rotavirus antigen. The Rotavirus-positive samples were further subjected to polyacrylamide gel electrophoresis (PAGE) to determine their RNA electropherotypes.

A total of 59 stool samples (19.9%) were Rotavirus positive with peaks observed in the cold dry season, among male children, and 6-10 years of age group.
