Psychological stress is a major provocative factor of symptoms in chronic inflammatory conditions. In recent years, interest in addressing stress responsivity through meditation training in health-related domains has increased astoundingly, despite a paucity of evidence that reported benefits are specific to meditation practice. We designed the present study to rigorously compare an 8-week Mindfulness-Based Stress Reduction (MBSR) intervention to a well-matched active control intervention, the Health Enhancement Program (HEP) in ability to reduce psychological stress and experimentally-induced inflammation. The Trier Social Stress Test (TSST) was used to induce psychological stress and inflammation was produced using topical application of capsaicin cream to forearm skin. Immune and endocrine measures of inflammation and stress were collected both before and after MBSR training. Results show those randomized to MBSR and HEP training had comparable post-training stress-evoked cortisol responses, as well as equivalent reductions in self-reported psychological distress and physical symptoms. However, MBSR training resulted in a significantly smaller post-stress inflammatory response compared to HEP, despite equivalent levels of stress hormones. These results suggest behavioral interventions designed to reduce emotional reactivity may be of therapeutic benefit in chronic inflammatory conditions. Moreover, mindfulness practice, in particular, may be more efficacious in symptom relief than the well-being promoting activities cultivated in the HEP program.

Traditional medicines especially the herbal paste is routinely prescribed by the herb sellers. The unsupervised combinations and preparations are easily available in our part of world. The demand and supply of such irrational combination is only based on the principle that anything natural is safe. Drugs and preparations made by the people who lack the scientific knowledge of traditional herbal medicines adversely affect the consumer. We put forward few complications that resulted after herbal paste application in those who already had visited the specialist but opted the easily available unsupervised herbal preparations.

OBJECTIVE: Lumbar spinal stenosis (LSS) is a common cause of chronic lumbar pain and disability. Conventional therapy approaches include analgesics and spinal surgery. Topical cantharidin applications are used for the treatment of severe chronic lumbar pain in traditional European medicine (TEM). We tested the pain-relieving effect of lumbar cantharidin blisters in a non-randomised controlled pilot study. PATIENTS AND METHODS: 28 consecutive patients with manifest LSS were included. The first 20 patients received a cantharidin blister, 8 patients served as controls (waiting list). Pain was assessed by means of a numeric visual analogue scale (VAS; 0 indicating no pain, 10 indicating strongest pain). Treatment started after a 3-day run-in phase, the blister was applied once for 12 h. RESULTS: Patients were comparable with respect to baseline pain. In the blister group, the pain score continuously improved from 7.2 +/- 2.1 at baseline to 2.9 +/- 2.3 (VAS) at day 7, whereas the score remained unchanged in control patients. Adjusted for baseline, the difference between the blister and the control group was estimated at 4.1 (95% CI: 2.4-5.9, p < 0.0001). The use of analgesics was slightly higher in the control group. No serious adverse events were observed. CONCLUSION: In this first study on the efficacy of cantharidin blisters, a clinically relevant pain-relieving short-term effect on LSS was observed. As the trial was non-randomised and only included a limited number of patients, the results should be interpreted with caution.

BACKGROUND: Hand-foot skin reaction is a distinctive cutaneous side-effect of antineoplastic kinase inhibitor-targeted therapy. Severe hand-foot skin reaction requires postponement of treatment or dose reduction. Histopathological studies of skin toxicity associated with kinase inhibitors are currently unavailable. OBJECTIVES: To report the clinical and histopathological findings of hand-foot skin reaction produced by the multikinase inhibitor sorafenib. METHODS: Nine patients with metastatic carcinoma-seven with renal cell carcinoma (RCC), one with melanoma and one with hepatocellular carcinoma (HCC)-received continuous, oral sorafenib 400 mg twice daily. Hand-foot skin reaction was defined and graded according to National Cancer Institute Common Toxicity Criteria 3.0. Biopsies from lesions of erythematous scaly or blistering skin were obtained from five cases (four RCC and one HCC). RESULTS: Seven of the nine (78%) patients developed hand-foot skin reaction characterized by well-demarcated, tender, erythematous papules and plaques with greyish blisters or hyperkeratotic, callus-like formations on palmoplantar surfaces and distal phalanges. Skin biopsy of hand-foot skin reaction lesions revealed epidermal acanthosis, papillomatosis, parakeratosis, dispersed dyskeratotic cells and keratinocyte vacuolar degeneration. Other skin toxicities included angular cheilitis, seborrhoeic dermatitis and perianal dermatitis. CONCLUSIONS: The clinical manifestations and histopathological features of sorafenib-induced skin reactions are unique. The most relevant histopathological findings of hand-foot skin reaction include keratinocyte vacuolar degeneration, the presence of intracytoplasmic eosinophilic bodies, and intraepidermal blisters in the stratum malpighii. Further studies are warranted to elucidate the mechanisms of this novel multitargeted kinase inhibitor-associated skin reaction.

OBJECTIVE: Cantharidimide cause blister. The effect of blister on immunoregulation was investigated. METHODS: Cantharidimide was placed on the skin, 48h later, the blister was analyzed by flow cytometry. RESULTS: The blister contained 1 x 10(6) - 1 x 10(7) cells per ml, most of which were neutrophils, macrophages, dendritic cells (DC), and IL-12 secreted by Thl cells. CONCLUSION: There are high concent of DC in the blister, which is differential and induce the secretion of Th1, the activation of T cell. The blister modulate the biological response of patients and is helpful for treatment with infective disease.

Heparin-induced thrombocytopenia syndrome is a serious, potentially life-threatening adverse reaction to the use of heparin anticoagulation therapy that can result in significant skin damage and organ morbidity. A case study design is used to describe the innovative use of a topical wound treatment (trypsin-balsam of Peru-castor oil ointment) on bullous lesions related to the effects of this syndrome. An elderly, morbidly obese woman was treated for 2 weeks with twice-daily applications of the product along with non-adherent oil emulsion dressings. Oozing decreased substantially within a few days and open blisters closed within 1 week. After 2 weeks of therapy, the bullous skin reaction was fully resolved with no recurrence. The results of this case study suggest that this topical product may have had a positive effect on the bullous lesions and should be considered for use in other similar significant integumentary reactions.

BACKGROUND: At the direction of the Food and Drug Administration, phenolphthalein was removed from all over-the-counter laxatives in 1999. Phenolphthalein was then replaced in most laxative products with the natural product senna from Cassia acutifolia Delile, which contains various anthraquinones. No data are available on the safety of senna use in children <6 years of age. OBJECTIVE: To describe the clinical outcomes of exposure to unintentional ingestion of senna-containing laxatives in young children. METHODS: All ingestion exposures of senna-containing laxatives in children <5 years of age from 6 poison centers over a 9-month period were evaluated. Inclusion criteria required 24-hour follow-up and the presence of diarrhea to confirm ingestion. Parents were told routinely that severe diaper rash was possible and to protect the perianal area with frequent cleansing and a barrier ointment if the child was wearing diapers. RESULTS: During the study period, 111 cases were reported: 19 children experienced no diarrhea, 4 were lost to follow-up, and 88 exposures were evaluated. Fifty-two children (59%) were =2 years old. Fifty children remained in diapers, 28 children were fully toilet trained, and 10 wore diapers (pull-up pants) overnight. Twenty-nine children (33%) experienced severe diaper rash. The mean +/- SD time to recognition of the diaper rash was 15.6 +/- 8.6 hours. Ten children (11%) had blisters and skin sloughing. There was a significant increase in severe diaper rash (p < 0.05) and onset of blisters and skin breakdown (p < 0.05) in children wearing diapers versus those who were fully toilet trained. The mean time to onset of blisters was 14.5 +/- 6.8 hours. Skin burns and loss were seen primarily on the buttocks and perineum, loosely following the diaper area. CONCLUSIONS: Unintentional ingestion of senna-containing laxatives in young children may potentially cause severe diaper rash, blisters, and skin sloughing.

AIMS: To determine whether the addition of high-dose tumour necrosis factor-alpha (TNF alpha) to isolated limb perfusion (ILP) with melphalan increases acute regional tissue toxicity compared to ILP with melphalan alone. METHODS: A retrospective, multivariate analysis of toxicity after normothermic (37--38 degrees C) and 'mild' hyperthermic (38--40 degrees C) ILPs for melanoma was undertaken. Normothermic ILP with melphalan was performed in 294 patients (70.8%), 'mild' hyperthermic ILP with melphalan in 71 patients (17.1%) and 'mild' hyperthermic ILP with melphalan combined with TNF alpha in 50 patients (12.0%). Toxicity was nil or mild (grades I--II according to Wieberdink et al.) in 339 patients (81.7%), and more severe acute regional toxicity (grades III--V) developed in 76 patients (18.3%). A stepwise logistic regression procedure was performed for the multivariate analysis of prognostic factors for more severe toxicity. RESULTS: On univariate analysis, 'mild' hyperthermic ILP with melphalan plus TNF alpha significantly increased the incidence of more severe acute regional toxicity compared to normothermic and 'mild' hyperthermic ILP with melphalan alone (36% vs 16% and 17%; P=0.0038). However, after ILP using TNF alpha no grade IV (compartment compression syndrome) or grade V (toxicity necessitating amputation) reactions were seen. Significantly more severe toxicity was seen after ILPs performed between 1991 and 1994 compared with earlier ILPs (33%vs 14%P=0.0001). Also, women had a higher risk of more severe toxicity than men (22% vs 7%; P=0.0007). After multivariate analysis, prognostic factors which remained significant were: sex (P=0.0013) and either ILP schedule (P=0.013) or treatment period (P=0.0003). CONCLUSIONS: Regional toxicity after 'mild' hyperthermic ILP with melphalan and TNF alpha was significantly increased compared to ILP with melphalan alone. This may be caused by increased thermal enhancement of melphalan due to the higher tissue temperatures (39--40 degrees C) at which the melphalan in the TNF alpha-ILPs was administered or by an interaction between high-dose TNF alpha and melphalan.

OBJECTIVE: To describe photosensitization after prenatal exposure to a toxic amount of methylene blue and to alert pediatricians that, in a review of the literature, photosensitization (which this dye is capable of) has not been reported as a complication of prenatal exposure. DESIGN AND PATIENTS: A descriptive report of physical findings and significant laboratory tests in a very low birth weight preterm infant with prenatal exposure to methylene blue and a comparison of this reported case with previously described patients' complications and treatment. SETTING: Neonatal intensive care unit. INTERVENTION: Monitoring of laboratory tests to assess for methylene blue toxicity: two exchange transfusions for methemoglobinemia, hemolytic anemia, and hyperbilirubinemia; phototherapy for hyperbilirubinemia; and pathologic examination of skin bullae. RESULTS: Within hours of exposure to phototherapy, redness developed on all exposed areas of the patient's skin (which was initially deep blue), followed by bullae and desquamation of about 35% of the total skin surface area. The desquamation of erythematous areas continued even after discontinuation of phototherapy. Complete re-epithelialization was attained by 3 weeks of age. In addition to this newly observed complication, the patient had other previously described toxic effects. CONCLUSION: We have reported a previously unrecognized complication associated with high prenatal exposure to methylene blue and treatment with phototherapy. Methylene blue phototoxicity may be related to the high prenatal dose of the dye relative to patient's small size and young gestational age.

BACKGROUND: Today it is generally accepted that every drug that possesses an active thiol group in its molecule is capable of inducing pemphigus in vivo and provoking acantholysis in vitro. We therefore suggested that plants, in particular those belonging to the Allium group, that contain several active compounds with stable disulfide and thiol groups in their molecule may cause the same. OBJECTIVE: To verify this hypothesis by investigating the in vitro acantholytic effect of three compounds of garlic. METHODS: Skin samples from donors were cultured in the presence of three compounds of garlic (i.e. allylmercaptan, allylmethylsulfide and allylsulfide) for 3 days. The skin samples were then processed for microscopic control for acantholysis. RESULTS: Results indicate that, indeed, the three garlic compounds tested are capable of inducing acantholysis in vitro. Focal and diffuse acantholysis was observed in the specimens from 4 out of 7 donors cultured in the presence of 6 and 9 mM of each of the allyl compounds for 3 days. Interestingly, tissues from a DR4+ donor proved to be more acantholysis prone than others, showing large blistering due to diffuse acantholysis, thus indicating that individual susceptibility plays a crucial role also in vitro. CONCLUSION: Garlic compounds with stable disulfide and thiol groups in their molecule are capable of inducing acantholysis in vitro. These findings lend further support to the theory that 'harmless' nutritional factors are capable of inducing acantholysis in vitro and possibly also in vivo. In view of these findings, it is suggested that nutritional factors should be added to the ever-growing list of exogenous factors capable of inducing pemphigus.

Sulfur mustard (HD; 1,1'-thiobis[2-chloroethane]) induces fluid-filled blisters in man but not in conventional laboratory animals. An animal model is needed to emulate both cytotoxic (vesicant) and vascular (irritant) responses of human skin to HD exposures. An acceptable model must permit reproducible comparisons of uniformly graded and dose-related HD control responses with reduced responses that may follow antivesicant treatments. Hairless guinea pigs were evaluated by exposing six or eight dorsal skin sites 12 mm in diameter to similar HD vapor concentrations for graded intervals (1-16 min). HD vapor was delivered under occlusive caps holding 10 microliters of HD in filter paper located 5 mm above the skin. Four-minute exposures induced moderate erythema, slight edema, and microblisters in 1 of 39 sites. Eight-minute exposures induced severe erythema, moderate edema, and microblisters in 31 of 40 sites. Gross blistering was not seen after use of vapor cups, but damage to basal cells resembled lesions of vesicant injury in man. The hairless guinea pig model, with graded HD vapor exposures, provides acceptable comparisons of responses. Exposures of both 4- and 8-min durations were used to show the feasibility of using this model to bioassay antivesicant topical protectants. These methods may be useful for measurements of irritant and cytotoxic responses of skin to other toxic vapors.

In 65 patients suffering from psoriasis treated with photochemotherapy and 32 healthy controls the dermo-epidermal junction was measured by experimental blistering. A significantly shortened blistering time was shown in PUVA-patients. The reasons in discussion are the increase of activated melanocytes (clear cells) in the basal membrane region and changes in the connective tissue by long term PUVA-therapy.
