Clinical and epidemiologic examinations of 260 workers engaged in enzyme production revealed the structure of skin disease incidence: mycoses--31%, atopic dermatitis--19%, contact dermatitis--9%, allergic, dermatitis--5%. The majority of these skin diseases were associated with hyperphosphatemia and monoaminoxidase (MAO) depression. Changes of alkaline phosphatase and MAO activities, serum albumins and gamma-globulins may be considered as sensitive markers of disease.

We have investigated the mechanisms by which topical corticosteroids modulate cutaneous immune reactions in man. Volunteers applied clobetasone butyrate 0.05% (Eumovate; EV), betamethasone valerate 0.1% (Betnovate; BV), clobetasol propionate 0.05% (Dermovate; DV), and control vehicles twice daily to forearm skin for 7 days. Steroid therapy significantly decreased the number of HLA-DR/T6 (CD1a) positive Langerhans cells (LCs) per mm2 in suction blister-derived epidermal sheets, expressed as a mean percentage of controls, as follows: EV 69.2%; BV 67.3%; DV 37.8%. LC antigen presenting capacity was determined in the allogeneic and autologous epidermal cell-lymphocyte reactions. The LC-dependent allostimulatory capacity of epidermal cells, expressed as a mean percentage of controls, was also significantly reduced by steroid therapy: EV 45.1%; BV 41.9%; DV 23.4%. Following therapy with clobetasol propionate 0.05%, the capacity of epidermal cells to present tetanus toxoid to, and to augment concanavalin A mediated lymphocyte stimulation of, autologous lymphocytes was reduced to 33.6% and 19.7% respectively of controls. Depression of epidermal cell allostimulatory capacity was not the result of a steroid-induced decrease in the production of epidermal cell-derived thymocyte activating factor (ETAF)/interleukin 1 by keratinocytes, since it could not be reversed by addition of exogenous interleukin 1. Indomethacin, added to block any potential prostaglandin synthesis during the culture period, did not restore the allostimulatory capacity of epidermal cells from steroid-treated sites. Addition of epidermal cells from DV-treated sites depressed the capacity of control epidermal cells to stimulate lymphocytes in the allogeneic epidermal-lymphocyte reaction. Our results demonstrate that the anti-inflammatory action of topical corticosteroids in man is associated not only with a reduction in the number of HLA-DR/T6 positive LCs, but also with a marked decrease in Langerhans cell-dependent T lymphocyte activation. The effects of the different steroids on both of these parameters correlated with their potency as determined in the standard occlusive vasoconstrictor assay. Topical corticosteroids are widely used for the treatment of inflammatory skin disorders, and inhibit not only the elicitation phase, but also the induction phase, of allergic contact dermatitis reactions.(ABSTRACT TRUNCATED AT 400 WORDS)

Acrolein is a highly toxic, reactive, and irritating aldehyde that occurs as a product of organic pyrolysis, as a metabolite of a number of compounds, and as a residue in water when used for the control of aquatic organisms. It is an intermediate in the production of acrylic acid, DL-methionine, and numerous other agents. Its major direct use is as a biocide for the control of aquatic flora and fauna. It is introduced to the environment from a variety of sources, including organic combustion such as automobile exhaust, cigarette smoke, and manufacturing and cooking emissions, as well as direct biocidal applications. Organic combustion from both fixed and mobile sources is the significant source of acrolein in the atmosphere; it represents up to 8% of the total aldehydes generated from vehicles and residential fireplaces and 13% of total atmospheric aldehydes. This reactive aldehyde also occurs in organisms as a metabolite of allyl alcohol, allylamine, spermine, spermidine, and the anticancer drug cyclophosphamide, and as a product of UV radiation of the skin lipid triolein. Furthermore, small amounts are found in foods; when animal or vegetable fats are overheated, however, large amounts are produced. Most human contact occurs during exposure to smoke from cigarettes, automobiles, industrial processes, and structural and vegetation fires. Besides cigarette smoke, occupational exposures are a common mode of human contact, particularly in industries that involve combustion of organic compounds. Firefighters, in particular, are exposed to extremely high levels during the extinguishment and overhaul phases of their work. Water may contain significant levels of the herbicide. It has been found in paper mill and municipal effluents at 20-200 micrograms/L, and at 30 micrograms/L as far as 64 km downstream from the point of application. The USEPA-recommended water quality criteria for freshwater are only 1.2 micrograms/L (24-hr avg) and 2.7 micrograms/L (maximum ceiling). Acrolein is highly reactive, and intercompartmental transport is limited. However, it is eliminated from aqueous environments by volatilization and hydration to beta-hydroxypropanal, after which biotransformation occurs, with a half-life of 7-10 d. The Koc for acrolein is 24, and it is not likely to be retained in soil; activated carbon adsorbs only 30% from solution. Thus, the aldehyde is either leached extensively in moist soil or volatilizes quickly from dry soil. It is eliminated from air by reaction with .OH (half-life, 0.5-1.2 d), NOx (half-life, 16 d), and O3 (half-life, 59 d), as well as by photolysis and wet deposition. As expected from its high water solubility, bioaccumulation is low. Acrolein is highly toxic by all routes of exposure. The respiratory system is the most common target: exposure causes localized irritation, respiratory distress, pulmonary edema, cellular necrosis, and increased susceptibility to microbial diseases. Additionally, acute inhalation studies verify that it is a severe respiratory irritant that affects respiratory rates. Respiratory rate depression may have a protective effect by minimizing vapor inhalation, thereby explaining the subadditive effect of acrolein when combined with the other toxic combustion by-products CO and HCHO. Liquid contact with the skin and eyes causes severe irritation, opaque or cloudy corneas, and localized epidermal necrosis, but no allergic contact dermatitis. The cardiovascular system is affected, resulting in increased blood pressure, platelet aggregation, and quick cessation of beating in perfused rat hearts. It may also inhibit mitochondrial oxidative phosphorylation in the myocardium. Acute LD50s and LC50s are low. Levels are 7-46 mg/kg and 18-750 mg/m3, respectively, in rats; aquatic organisms are affected above 11.4 micrograms/L.(ABSTRACT TRUNCATED)

The Occupational Physicians' Reporting Activity (OPRA) surveillance scheme for occupational physicians has now been in place for 4 years. During this period, an estimated 43,764 new cases of work-related disease have been reported. Musculoskeletal conditions make up nearly half (49%) of all cases; mental ill-health and skin disease account for 20% each, with respiratory conditions (8%) and hearing loss (5%) seen in lower proportions. Overall, eight of 42 diagnoses made up four-fifths of the new cases reported by occupational physicians. These were hand and arm disorders (8052 estimated cases), contact dermatitis (7104), disorders of the lumbar spine (6000), anxiety and depression (4788), work-related stress (3336), hearing loss (2100), elbow disorders (2040), and asthma (1680). Dermatitis and hearing loss were most frequent in manufacturing industries, lower back complaints in health care, and upper limb disorders in automotive manufacture. Psychiatric illnesses presented a different pattern, mainly affecting those in health, education and social service.

Burning mouth syndrome is the occurrence of oral pain in a patient with a normal oral mucosal examination. It can be caused by both organic and psychologic or psychiatric factors, which can be broken down into local, systemic. psychologic or psychiatric, and idiopathic causes. The most frequently associated conditions are psychiatric (depression, anxiety, or cancerphobia); xerostomia; nutritional deficiency; allergic contact dermatitis; candidiasis; denture-related pain: and parafunctional behavior. Multiple different factors contributing to the oral pain are common, and a systematic approach to the evaluation is important. Identification of correctable causes of BMS should be emphasized and psychiatric causes should not be invoked without thorough evaluation of the patient. A directed history and careful oral examination must be completed to exclude local diseases and identify clues to potential causes. Assessment of medications, psychiatric history and background, and selected laboratory and patch tests may help identify the etiologies of these symptoms. Treatment should be tailored to each patient and may best be managed in a multidisciplinary approach with input from dermatologists, dentists, psychiatrists. otorhinolaryngologists, and primary care providers. A thoughtful and structured evaluation of the patient with BMS has been associated with improvement in about 70% of patients. The remaining patients may benefit from empiric therapy with a chronic pain protocol and continued supportive interactions.

Occupational hand eczema (OHE) is the most frequently recognized occupational disease in Denmark, and despite governmental attempts to reduce exposure to harmful occupational allergens, the number of new cases has remained almost unchanged since the mid-1990s. Some studies have indicated that OHE has considerable impact on quality of life (QoL) and may lead to depression. The aims of the study were to determine risk factors for low QoL, the frequency and severity of depression among OHE patients and changes in QoL and depression after 12 months of follow up. The study population, 758 patients, comprised all new recognized cases from the Danish National Board of Industrial Injuries Registry between October 2001 and November 2002. All patients received a questionnaire to determine impairment of QoL and depressive symptoms. A similar follow-up questionnaire was posted after 1 year. The response rate was 82% at baseline and 91% at follow up. The mean Dermatology Life Quality Index total score was 5.5 for all patients and 7.8 for severe OHE cases. Severe OHE cases and lower socioeconomic status were independently associated with low QoL. The prevalence of moderate-to-severe depression was 9%. Only minor changes in QoL and depressive symptoms were found after 12 months of follow up.

Many dermatologic diseases, including vitiligo and other pigmentary disorders, vascular malformations, acne, and disfiguring scars from surgery or trauma, can be distressing to pediatric patients and can cause psychological alterations such as depression, loss of self-esteem, deterioration of quality of life, emotional distress, and, in some cases, body dysmorphic disorder. Corrective camouflage can help cover cutaneous unaesthetic disorders using a variety of water-resistant and light to very opaque products that provide effective and natural coverage. These products also can serve as concealers during medical treatment or after surgical procedures before healing is complete. Between May 2001 and July 2003. corrective camouflage was used on 15 children and adolescents (age range, 7-16 years; mean age, 14 years). The majority of patients were girls. Six patients had acne vulgaris; 4 had vitiligo; 2 had Becker nevus; and 1 each had striae distensae, allergic contact dermatitis. and postsurgical scarring. Parents of all patients were satisfied with the cosmetic cover results. We consider corrective makeup to be a well-received and valid adjunctive therapy for use during traditional long-term treatment and as a therapeutic alternative in patients in whom conventional therapy is ineffective.

Patients with venous insufficiency commonly develop complications which can result in significant morbidity and occasional mortality. Venous leg ulcers, the most prevalent type of lower extremity ulcer, are the most frequent sequela of venous insufficiency and negatively affect quality of life for the patient. Most have focused on venous ulceration, but other complications may arise including dermatitis, atrophie blanche, lipodermatosclerosis, and malignancy. Contact dermatitis is a common complication seen in the treatment of venous disease. Patients with venous insufficiency have a disrupted epidermal barrier, making them more susceptible than the general population to contact sensitization and subsequent dermatitis. Venous dermatitis is often the first manifestation of venous insufficiency and needs to be addressed promptly. Atrophie blanche, an end point of a variety of conditions, appears as atrophic plaques of ivory white skin with telangiectasias. Lipodermatosclerosis is an indurated plaque in the medial malleolus which can, at times, be quite tender and painful. Malignant degeneration is a rare but important complication of venous disease since tumors which develop in the setting of an ulcer tend to be more aggressive. Pain is a feature of venous disease often overlooked and commonly undertreated. Finally, psychosocial issues such as anxiety and depression are more common in patients with venous disease and should be adequately addressed. Recognizing these complications of chronic venous insufficiency is important as early intervention is the key to preventing unnecessary patient suffering and discomfort.

Claims of benefits of aromatherapy for cancer patients include reduced anxiety levels and relief of emotional stress, pain, muscular tension and fatigue. The objective of this paper is to provide an updated descriptive, systematic review of evidence from pre-clinical and clinical trials assessing the benefits and safety of aromatherapy for cancer patients. Literature databases such as Medline (via Ovid), the Cochrane database of systematic reviews, Cochrane Central were searched from their inception until October 2010. Only studies on cancer cells or cancer patients were included. There is no long lasting effect of aromatherapy massage, while short term improvements were reported for general well being, anxiety and depression up to 8 weeks after treatment. The reviewed studies indicate short-term effects of aromatherapy on depression, anxiety and overall wellbeing. Specifically, some clinical trials found an increase in patient-identified symptom relief, psychological wellbeing and improved sleep. Furthermore, some found a short-term improvement (up to 2 weeks after treatment) in anxiety and depression scores and better pain control. Although essential oils have generally shown minimal adverse effects, potential risks include ingesting large amounts (intentional misuse); local skin irritation, especially with prolonged skin contact; allergic contact dermatitis; and phototoxicity from reaction to sunlight (some oils). Repeated topical administration of lavender and tea tree oil was associated with reversible prepubertal gynecomastia.

There has been little epidemiological evidence that has comprehensively clarified whether alterations in lifestyle, such as sleep quality and dietary intake, explain changes in the skin condition of healthy young adults. Therefore, the aim of our study was to elucidate the association between skin condition and lifestyle behaviors such as diet and sleep, after statistically controlling confounding factors. The subjects were 54 participants who were aged 20-32 y, and who attended college in the Kanto region (in Japan). Transepidermal water loss (TEWL) was obtained by putting a probe on the skin surface based on the European Society of Contact Dermatitis guidelines for TEWL measurements. Self-administered questionnaires on demographic characteristics, dietary habits, and health status, such as sleep condition, depression, and fatigue, were handed to participants on the day of measurement. We found that lower sleep efficiency was significantly associated with higher TEWL (p=0.023), while other demographic factors, dietary intakes, and eating behaviors were not (p>0.05). This significant association remained unchanged after controlling for confounding variables, such as sex, BMI, and dietary intake. Our findings may have important implications in the development of valuable health strategies that may suggest behavior modifications for young to middle-aged men and women.
