Metal-working fluids (MWFs) are used in machining and grinding operations to cool the tool and work, reduce the friction between the tool and work, improve the surface integrity of the work piece, and increase tool life and productivity. Health problems have been reported among workers exposed to MWFs, including incidences of respiratory, digestive and skin cancers, and increased rates of cough and phlegm. This paper reviews and discusses issues concerning health risks from exposure to MWFs in machining and grinding operations, the various factors that influence the degree of exposure, and control methods to reduce exposure to metal-working fluids.

Even in the twenty-first century, welding is still a common and a highly skilled occupation. The hazardous agents associated with welding processes are acetylene, carbon monoxide, oxides of nitrogen, ozone, phosgene, tungsten, arsenic, beryllium, cadmium, chromium, cobalt, copper, iron, lead, manganese, nickel, silver, tin, and zinc. All welding processes involve the potential hazards for inhalation exposures that may lead to acute or chronic respiratory diseases. According to literature described earlier it has been suggested that welding fumes cause the lung function impairment, obstructive and restrictive lung disease, cough, dyspnea, rhinitis, asthma, pneumonitis, pneumoconiosis, carcinoma of the lungs. In addition, welding workers suffer from eye irritation, photokeratitis, cataract, skin irritation, erythema, pterygium, non-melanocytic skin cancer, malignant melanoma, reduced sperm count, motility and infertility. Most of the studies have been attempted previously to evaluate the effects of welding fumes. However, no collectively effort illuminating the general effects of welding fumes on different organs or systems or both in human has not been published. Therefore, the aim of this review is to gather the potential toxic effects of welding fumes documented by individual efforts and provide informations to community on hazards of welding.

A 56-year-old patient developed sarcoidosis on top of an old eyelid scar from previous removal of an eyelid basal cell carcinoma 16 years prior to presentation. An irregular, firm, ill-defined subcutaneous mass was palpable beneath an old minimally visible scar from the previous surgery. The patient had a strong family history of sarcoidosis and persistent dyspnea and cough for the past two years, which were only elicited after the histopathology results came out with multiple non-caseating granulomas with multi-nucleated giant cells. Sarcoidosis should be considered in the differential diagnosis of recurrent eyelid skin cancers especially if the external appearance or the duration after the initial surgery does not fit the criteria for recurrence.

Cancer chemoprevention is a dietary or therapeutic strategy to prevent, suppress, or delay carcinogenesis either at initiation or progression level with nontoxic agents. Use of natural dietary compounds has been a major chemopreventive approach to modulate tumorigenic pathways. In the present study, we have evaluated Lagenaria siceraria (bottle gourd), a common vegetable of Indian household for its chemomodulatory potential. The fruit has been used in traditional medicine for a very long time for health benefits and to cure pain, ulcers, fever, cough, asthma, and other bronchial disorders. However, despite its reported beneficial effect the chemo modulatory potential of this plant has not been reported. Therefore chemopreventive effect of bottle gourd juice (BGJ) was studied against 7,12-dimethylbenz(a)anthracene (DMBA) plus croton oil induced skin papillomagenesis in Swiss albino mice. The effect was studied both at antiinitiation and antiinitiation/promotion level followed by histopathological study. A dose of 2.5% and 5% given in drinking water showed significant decrease in papilloma number, papilloma incidence, papilloma multiplicity, papilloma latency, papilloma volume, and papilloma size in different size range. Histopathological study showed chemopreventive effect by minimizing loss of stratification, a decrease in number of epithelial layers, reducing dermal infiltration and protection for various cytoplasmic changes. Higher dose of BGJ was found to be more effective than lower dose and the chemopreventive effect was maximum for antiinitiation/promotion treatment. Altogether, this study reports the chemopreventive effect of Lagenaria siceraria on skin papillomagenesis for the first time and suggests that its consumption may help in suppression of skin cancer.

Acacia nilotica is a plant species that is almost ubiquitously found in different parts of the world. Various preparations of it have been advocated in folk medicine for the treatment of tuberculosis, leprosy, smallpox, dysentery, cough, ophthalmia, toothache, skin cancer as astringent, antispasmodic, and aphrodisiac since immemorial times. The present study investigates the antibacterial, antifungal, antiviral, and immunomodulatory potential of hot aqueous extract (HAE) of Acacia nilotica leaves. On dry matter basis, the filtered HAE had a good extraction ratio (33.46%) and was found to have carbohydrates, glycosides, phytosterols, phenolic compounds, saponins, and flavonoids as major constituents. HAE produced dose dependent zone of inhibition against Klebsiella pneumoniae, Pseudomonas aeruginosa, E. coli, Bacillus cereus, Staphylococcus aureus, and Streptococcus uberis and fungal pathogens Aspergillus niger and Aspergillus fumigates; however, no antiviral activity was recorded against IBR virus. HAE of A. nilotica revealed both proliferative and inhibitory effects on the rat splenocytes and IL-10 release depending on the dose. Detailed studies involving wide spectrum of bacterial, fungal, and viral species are required to prove or know the exact status of each constituents of the plant extract.

The lungs receive the entire venous drainage of the body. This explains the high incidence of pleuropulmonary metastases originating from several cancers. The goal of this is to study the clinical manifestations of pleuro-pulmonary metastases originating from extra-thoracic cancers. We conducted a retrospective study of patients with pleuro-pulmonary metastasis whose data were collected in our department between January 2006 and december 2014. 76 patient medical records were studied. The average age was 50 years (aged 21-89 years) with a male predominance in 57.8% of cases. Clinical symptoms were mainly cough (32.8% of cases), dyspnea (23.7% of cases) and hemoptysis (11.2%). Primary cancers responsible for various pleuro-pulmonary metastases found in our case series were dominated by breast cancers in 27.6% of cases, gastro-intestinal cancers in 15.8% of cases, genital cancers in 9, 2% of cases, sarcomas in 7.8% of cases, renal cancers in 5.2% of cases, bladder cancers in 5.2% of cases, prostate cancers in 3.9% cases, ENT cancers in 3.9% of cases, thyroid cancers in 3.9% of cases, skin cancers in 2.6% of cases and cancers of unknown primary origin in 14.4% of cases respectively. Several radiologic features of pleuro-pulmonary metastases have been found in our case series; they can be isolated or combined. The most common radiologic aspect was multiple pulmonary nodules in 52.6% of cases, followed by pleurisies in 34.2% of cases, diffuse micronodules in 23.6% of cases and a solitary nodule in 3.94% of cases. Secondary pleuropulmonary cancers are frequent. They come in 3rd place after lymph nodes and liver metastases and are found in 30% of autopsies of patients with neoplasia.
