Yoga as a Therapeutic Component in Treating Chemical Dependency

The purpose of this article is to examine the parallel in yoga, addiction, and the therapeutic process. Chemical dependency is a self-destructive process that weakens and unbalances the individual physically, emotionally, and spiritually. Yoga is a three-fold process that can rebuild these aspects of self, serving to counteract further progression of the disease. Yoga and meditation can be effective in helping the patient regain his/her vital center of energy, satisfaction and stability while making positive changes in their lives. Emphasis is placed on how the application of yoga in conjunction with treatment can accelerate the rehabilitative process.     

Crude 4-methylcyclohexanemethanol (MCHM) did not cause skin irritation in humans in 48-h patch test

Crude 4-methylcyclohexanemethanol (MCHM) is an industrial chemical used to wash and clean coal. On January 9th, 2014 approximately 10,000 gallons of a mixture containing crude MCHM were released into the Elk River near Charleston, West Virginia, contaminating the local water supply. Following the spill, residents reported numerous health complaints, and sought medical attention for ailments including rashes and itching. The relationship between the complaints and the spill were unknown, as such symptoms are reported frequently in the background. In this study, the primary irritation potential of crude MCHM was evaluated in 206 individuals who underwent 48?hour semi-occluded patch testing. MCHM concentrations assessed in this study were 1, 5, 15, and 100?ppm. No appreciable skin reactions were observed in individuals at any concentration. Three of the five concentrations evaluated were above the highest measured concentration of MCHM in the tap water of residents in West Virginia (3.7?ppm). The results of this study suggest that crude MCHM would not be a dermal irritant for the vast majority, if not all, potentially exposed persons at the concentrations in the water reported after the spill.     

Cadmium accumulation,sub-cellular distribution and chemical forms in rice seedling in the presence of sulfur

Changes in cadmium (Cd) accumulation, distribution, and chemical form in rice seedling in the joint presence of different concentrations of sulfur (S) remain almost unknown. Therefore, the indoor experiments were performed to determine the accumulation, sub-cellular distribution and chemical forms of Cd under three S levels in rice seedling for the first time. The result showed that Cd accumulation in rice roots was more than in shoots. Sub-cellular distribution of Cd in rice roots and shoots indicated that the largest proportion of Cd accumulated in cell walls and soluble fractions. As S supply increased, the proportion of Cd in cell walls reduced, while it increased in the soluble fractions. The majority of Cd existed in inorganic form, and then gradually changed to organic forms that included pectates and proteins with increased S supply. The results showed that S supply significantly influenced Cd accumulation, distribution, and chemical forms, suggesting that S might provide the material for the synthesis of sulfhydryl protein and thereby affect Cd stress on plants. These observations provided a basic understanding of potential ecotoxicological effects of joint Cd and S exposure in the environment.

Chemical allergy in humans: Fresh perspectives

Abstract

There is considerable interest in the immunobiological processes through which the development of allergic sensitization to chemicals is initiated and orchestrated. One of the most intriguing issues is the basis for the elicitation by chemical sensitizers of different forms of allergic reaction; that is, allergic contact dermatitis or sensitization of the respiratory tract associated with occupational asthma. Studies in rodents have revealed that differential forms of allergic sensitization to chemicals are, in large part at least, a function of the selective development of discrete functional sub-populations of CD4⁺ and CD8⁺ T-lymphocytes. Evidence for a similar association of chemical allergy in humans with discrete T-lymphocyte populations is, however, limited. It is of some interest, therefore, that two recent articles from different teams of investigators have shed new light on the role of polarized T-lymphocyte responses in the development of allergic contact dermatitis and occupational asthma in humans. The implications for understanding of chemical allergy in humans are explored in this Commentary.     

A Study of Closure of Tympanic Membrane Perforations by Chemical Cauterisation

To study the effectiveness of chemical cautery with patching on chronic tympanic membrane perforations of the pars tensa. Thirty-eight patients with dry tympanic membrane perforations due to inflammatory or traumatic etiology were selected after treating the primary etiological factors like septal deviation and allergic rhinitis. Fifty percentage silver nitrate was used to cauterize the margin and the perforation was covered with thin sterile aluminium foil as a patch. A maximum number of five applications were made, and the patients were followed up for the next 5 years. In this series of 38 patients, highest success was noted among those patients with traumatic perforation, while larger perforations were reduced to small pinhole sizes which were successfully closed by myringoplasty. An overall success rate of 73.75% was achieved. This is a time tested useful method which was popularized by Derlacki (1953), to close small to moderate sized tympanic membrane perforation and should be considered as a first line management in the treatment of tympanic membrane perforation prior to any surgical intervention. Apart from being a simple and economical mode of treatment, it is associated with minimal complications. Though various materials have been used to modify this technique, the principle remains the same and the results obtained in this study is comparable with the previous ones.

Vasogenic Edema of the Basal Ganglia after Intra-Arterial Administration of Nimodipine for Treatment of Vasospasm

The intra-arterial administration of nimodipine (IAN) is commonly used for cerebral vasospasm refractory to medical treatments. We report two cases of vasogenic edema after IAN. Our patients with aneurismal subarachnoid hemorrhage presented with vasospasm, which was treated by IAN. Consequently, vasogenic edema developed in the basal ganglia. Reperfusion following IAN for vasospasm may have the potential for inciting vasogenic edema in the ischemic brain.
