Adverse impact of occupational exposure on Laborers of cement industry have scalp psoriasis and Pityriasis amiantacea with deficiency of zinc and selenium: impact of mineral supplement.

The relationship between occupational exposure and different skin diseases including scalp psoriasis and Pityriasis amiantacea has been studied. The information about imbalance of essential trace elements in psoriatic patients is still scarce. In the present follow-up study, the scalp hair and blood samples of patients (labors of cement factory) have different skin disorders (plaque's psoriasis and Pityriasis amiantacea) and were analyzed for zinc (Zn) and selenium (Se) before and after treatment with mineral supplements.

Evaluate the effect of cadmium on levels of zinc in scalp hair and blood samples of smoker and nonsmoker psoriatic patients at different stage.

Psoriasis, a skin inflammatory disease, originates from dysregulated interactions of the immune system and environmental factors. In the present study, cadmium (Cd) and zinc (Zn) were analyzed in biological samples (blood and scalp hair) of smoker and nonsmoker males who have mild and severe psoriasis. The patients were evaluated according to criteria based on the standard clinical diagnosis and classified into mild and severe psoriasis groups using the Psoriasis Area Severity Index (PASI) score.

Exposure of children to arsenic in drinking water in the Tharparkar region of Sindh, Pakistan.

Humans can be exposed to arsenic (As) through air, drinking water, and food. The aim of this study was to calculate the hazard quotient (HQ) of As, based on its concentration in drinking water and the scalp hair of children (males) belonging to two age groups (5-10 and 11-14 years) who consumed water contaminated with different concentrations of As. The water samples were collected from As-exposed and nonexposed areas, which were classified as low-exposed (LE), high-exposed (HE), and nonexposed (NE) areas.

Toxic Risk Assessment of Arsenic in Males Through Drinking Water in Tharparkar Region of Sindh, Pakistan.

Humans are exposed to arsenic (As) through air, drinking water, and food. The arsenic (As) hazardous quotient was calculated on the basis of its concentration in drinking water of different origin and scalp hair of male subjects (n = 313), residents of different exposed and non-exposed areas of Sindh, Pakistan. The total As was determined in water and scalp hair samples, while As species were determined in water samples by advance extraction methodologies.

Estimation of Nickel in Different Smokeless Tobacco Products and Their Impact on Human Health of Oral Cancer Patients.

It has been extensively investigated that the chewing of smokeless tobacco (SLT) products may enhance the inflammation of the oral cavity. The aim of the present study is to evaluate the relationship between nickel (Ni) exposure via different SLT products with oral cancer (different sites) incidence in the population of Sindh, Pakistan. The different brands of SLT products (mainpuri, gutkha, and moist snuff) commonly consumed by the studied population were analyzed for Ni contents.

Correlation of Arsenic Levels in Smokeless Tobacco Products and Biological Samples of Oral Cancer Patients and Control Consumers.

It has been extensively reported that chewing of smokeless tobacco (SLT) can lead to cancers of oral cavity. In present study, the relationship between arsenic (As) exposure via chewing/inhaling different SLT products in oral cancer patients have or/not consumed SLT products was studied. The As in different types of SLT products (gutkha, mainpuri, and snuff) and biological (scalp hair and blood) samples of different types of oral cancer patients and controls were analyzed.

Variation in the Levels of Aluminum and Manganese in Scalp Hair Samples of the Patients Having Different Psychiatric Disorders with Related to Healthy Subjects.

There is very limited information available on the role of trace elements in psychiatric disorders (PSD). Immense pieces of evidence support the idea that exposure to trace and toxic metals, such as aluminum (Al) and manganese (Mn), may be factors or cofactors in the etiopathogenesis of a variety of psychiatric disorders. The aim of our study was to assess the Al and Mn in scalp hair samples of 102 patients having different types of psychiatric disorder PSD diseases together with 120 referent subjects of male patients in the age group of 45-60 years.

Correlation of aluminum and manganese concentration in scalp hair samples of patients having neurological disorders.

Neurodegenerative diseases are thought to be multifactorial, while metals (aluminum and manganese) can be involved as cofactors in abnormalities or suspected of being risk factors for this disorder. The aim of our study was to assess the aluminum (Al) and manganese (Mn) concentrations in scalp hair samples of 397 patients having different types of neurological disorder diseases. For comparative purpose, scalp hair samples of 201 control subjects does not have any neuro-disorders of same age group (30-60 years) and were selected as referents.

Scalp hair and blood cadmium levels in association with chewing gutkha, mainpuri, and snuff, among patients with oral cancer in Pakistan.

Background: It has been reported that smokeless tobacco (SLT) chewing can lead to caners of oral cavity. In this study, the relationship between cadmium exposure via consumption of different SLT products by patients with oral cancer with related to referents belongs to different cities of Pakistan are investigated.

Methods: The cadmium in different types of SLT products (gutkha, mainpuri and snuff) consumed by studied population and biological samples (scalp hair and blood) of cancerous and healthy subjects were analyzed.

Interaction between essential elements selenium and zinc with cadmium and mercury in samples from hypertensive patients.

The abnormal metabolism of metal ions plays an important role in health and disease conditions; hence, the studies about them have received much interest. The objective of this study was to evaluate the association between trace and toxic elements zinc (Zn), cadmium (Cd), selenium (Se), and mercury (Hg) in biological samples (scalp hair, blood, and urine) of hypertensive patients (n = 257), residents of Hyderabad, Pakistan. For comparison purpose, the biological samples of age-matched healthy controls were selected as referents.

Determination of nickel in blood and serum samples of oropharyngeal cancer patients consumed smokeless tobacco products by cloud point extraction coupled with flame atomic absorption spectrometry.

Oropharyngeal cancer is a significant public health issue in the world. The incidence of oropharyngeal cancer has been increased among people who have habit of chewing smokeless tobacco (SLT) in Pakistan. The aim of present study was to evaluate the concentration of nickel (Ni) in biological samples (whole blood, serum) of oral (n = 95) and pharyngeal (n = 84) male cancer patients.

Interaction between selenium and mercury in biological samples of Pakistani myocardial infarction patients at different stages as related to controls.

It has been speculated that trace elements may a play role in the pathogenesis of heart diseases. In the present study, we aimed to assess the levels of selenium (Se) and mercury (Hg) in biological samples (whole blood, urine, and scalp hair) of myocardial infarction (MI) patients of both genders (age range 45-60 years) at the first, second, and third heart attack (n = 130), hospitalized in a cardiac ward of a civil hospital of Hyderabad City (Pakistan). For comparison, healthy age-matched referent subjects (n = 61) of both genders were also selected.

Levels of arsenic, cadmium, lead, manganese and zinc in biological samples of paralysed steel mill workers with related to controls.

The determination of essential trace and toxic elements in the biological samples of human beings is an important clinical screening procedure. This study aimed to assess the possible effects of environmental exposure on paralysed male workers (n = 75) belonging to the production and quality control departments of a steel mill. In this investigation, the concentrations of arsenic, cadmium, lead, manganese and zinc were determined in biological samples (blood, urine and scalp hair samples) of exposed paralysis and non-paralysed steel mill workers.
