Blue nevus is an uncommon pigmented tumor of dermal melanocytes that has traditionally been classified into common and cellular variant. It is usually a skin tumor in adults but can become apparent in early childhood or even be present at birth. Malignant blue nevus is a rare melanocytic tumor of the skin arising from a preexisting cellular blue nevus. We report a multinodular blue nevus of the left ear in an 11-year-old girl who also had 2 intracranial melanocytic lesions. Differential diagnosis between metastases from malignant blue nevus and neurocutaneous melanosis is discussed.

Melanosis and leucomelanosis with or without keratosis are the earliest symptoms of arsenicosis. Uneven distribution of arsenical melanosis and leucomelanosis in skin led us to investigate the possibility of preferential secretion of arsenic and three constituents of sweat; cholesterol, vitamin E, and zinc. Twenty-four-hour skin secretion was collected from skin lesions and unaffected sites of 20 patients. Skin secretions were collected from 20 people exposed to arsenic-contaminated drinking water and 20 healthy, unexposed individuals. The secretion of arsenic from the skin of healthy controls (mean ± SE; unit: μg/in.(2) of skin/24 h; chest: 0.6 ± 0.2; back: 0.3 ± 0.1; abdomen: 0.5 ± 0.2) was increased several folds in arsenic-exposed controls (chest: 8.4 ± 1.8; back: 8.3 ± 1.9; abdomen: 6.7 ± 1.8) and patients (chest: 9.2 ± 1.3; back: 7.8 ± 1.3; abdomen: 5.2 ± 1.0). There was no difference in the skin lesions and unaffected sites in patients. However, the secretion of cholesterol was significantly lower in the chest of patients (190 ± 36) and healthy controls (686 ± 100) (p vitamin E were low in healthy controls (chest: 8.5 ± 3.1; back: 5.2 ± 1.7; and abdomen: 8.7 ± 2.4), higher in arsenic-exposed controls (chest: 30.2 ± 8.1; back: 16.3 ± 8.9; and abdomen: 24.8 ± 9.3), and highest in patients [chest: 91.4 ± 14.9 (p skin lesions showed no alteration in secretion of arsenic, although the secretion of cholesterol, vitamin E, and zinc was changed. Potential implications are discussed.

Conjunctival amelanotic malignant melanoma arising in primary acquired melanosis sine pigmento.

The authors describe an amelanotic malignant melanoma of the conjunctiva in association with primary acquired melanosis (PAM) sine pigmento, and highlight the clinical and pathologic features of this rare entity. Histopathologic and immunohistochemical studies were performed on a conjunctival tumor in a 54-year-old white woman. Case report. Histopathologic examination revealed an invasive amelanotic melanoma of the conjunctiva, with anterior orbital extension arising from intraepithelial dysplastic melanocytes that lacked melanin pigment (PAM sine pigmento). Both the malignant melanoma cells and the intraepithelial dysplastic melanocytes in the areas of PAM exhibited S-100 and HMB-45 positivity. The patient underwent an orbital exenteration that disclosed tumor within the anterior orbit inferiorly. Amelanotic invasive malignant melanoma can arise in association with PAM sine pigmento, as seen in our patient who had orbital invasion necessitating exenteration. This aggressive form of conjunctival melanoma is often associated with a poor prognosis and risk of metastatic disease. Absence of conjunctival pigmentation in PAM sine pigmento prevents early clinical detection of this variant of PAM. This lack of pigmentation also makes clinical diagnosis virtually impossible, and diagnosis can only be established histopathologically. Awareness of this nonpigmented variety of PAM is crucial for early recognition and appropriate management of the associated melanoma.

Vyanga is one of the Kshudraroga, characterized by the presence of Niruja (painless) and Shavavarna Mandalas (bluish-black patches) on face. It is one of the most common diseases as regards the face is concerned. On the basis of clinical features, it can be compared with facial melanosis, one of the hyper pigmented disorders. Drugs with Rakta Prasadaka, Twak Prasadaka and Varnyakara properties are helpful in the management of Vyanga, that pacifies aggregated Doshas and help in Raktashodhana (blood purification). To evaluate the efficacy of Arjunatwak Lepa and Panchanimba Churna in Vyanga. In this study, the trial drugs used were Arjunatwak Churna for Lepa (tropical application) and Panchanimba Churna for oral administration. A total 30 patients of Vyanga were selected from outpatient department and inpatient department of Shalakya Tantra Department and allotted randomly in two groups. In group-A, the patients were treated with external application of Arjunatwak Churna and Madhu for 21 days, while in group-B, patients received Panchanimba Churna orally for 21 days in addition to Arjunatwak Churna for Lepa. Effect of therapy on chief complaint i.e., bluish-black pigmentation in Group A was 60% relief, while in Group B 80% relief was found. The clinical study has shown that combined therapy gives better results than topical treatment.

Sixty-two patients were treated by some combination of cryotherapy and surgery with an average follow-up of 3.3 years for one of the following diseases: focal or diffuse flat conjunctival primary acquired melanosis (PAM) with atypia but without a nodule of melanoma (10 cases); unifocal malignant melanoma with or without focal or diffuse PAM (30 cases); and multinodular/multicentric melanoma with and without PAM (22 cases). Of the ten patients who had PAM with atypia, invasive nodules of malignant melanoma did not develop. A second treatment was required to control the disease in four of the ten patients with extensive or diffuse lesions, and one has mild persistent disease. Of the 30 patients with unifocal nodules of malignant melanoma, 27 remained free of recurrence after one treatment, and 2 are asymptomatic after two treatments. One patient with a thick nodule at presentation required a parotidectomy and radical neck dissection for cervical metastases after recurrence in the conjunctival sac. In the group of 22 patients with multinodular malignant melanoma, only two did not have recurrent disease after one treatment. Of those who received multiple therapies, seven remained free of recurrence for at least 2 years after the last treatment; regional or distant metastases developed in nine; four required exenteration; and eight died. Conjunctival adjunctive cryotherapy avoids exenteration in extensive lesions of pure PAM and in unifocal melanoma, but even after multiple therapies, multinodular malignant melanoma had a 45% rate of metastasis. Metastasis was related to the presence of PAM sine pigmento in four patients (microscopically but not clinically detectable PAM); to the location of the nodules (9 of 10 patients who experienced metastases had forniceal, palpebral, and/or caruncular nodules); to the thickness or depth of invasion of the nodules (greater than 2 mm); and to the development of intralymphatic spread ("in-transit" local metastasis) within the

Twenty-eight consecutive patients affected by these rare angiomatous melanotic neuroectodermal disorders are assessed. The diagnostics value and clinical correlation of neuroimaging methods, both CT and MR, are established. Patients with Sturge-Weber syndrome (15 cases), Klippel-Trenaunay syndrome (1 case), Rendu-Osler disease (3 cases), multiple hemangiomatosis (4 cases), von Hippel-Lindau syndrome (3 cases), neuro cutaneous melanosis (1 case) and hypo melanosis of Ito (1 case) are included. In vascular phacomatosis, neuroimaging methods usually contribute to the positive diagnosis. In melanotic disorders, the neuroradiological findings most often are unspecific and do not contribute to the diagnosis of the disease

The authors noted an unusual finding in the fallopian tubes of a 31-year-old woman who had received external and internal whole pelvis radiotherapy for squamous cell carcinoma of the cervix. Aggregates of macrophages containing pigment, identified in a subepithelial location, were reminiscent of melanosis coli, which is caused by abuse of anthracene-containing laxatives. Electron microscopic examination of the pigment revealed cytoplasmic material with the appearance of lipofuscin, identical to the pigment described in cases of colonic melanosis. After a careful study of possible etiologic agents, it was concluded that the pigment most likely resulted from cellular damage caused by radiotherapy. The authors are not aware of any other reported case of this entity, which will be called pigmentosis tubae

Arsenic exposure through drinking water is a major global public health problem and is associated with an enhanced risk of various cancers including skin cancer. In human skin, arsenic induces precancerous melanosis and keratosis, which may progress to basal cell and squamous cell carcinoma. However, the mechanism by which these pathophysiological alterations occur remains elusive. In this study, we showed that sub-chronic arsenic exposure to SKH-1 mice induced unfolded protein response (UPR)...

Full Text Available Prediction of bacterial growth, survival or reduction in food matrices is needed for microbiological risk assessment. The survival of Salmonella Typhimurium on surfaces of raw shrimps at low temperature was studied, in the presence of sodium metabisulfite which is often used to prevent melanosis. The growth and/or reduction rates were quantified using DMFit software with Baranyi model and or linear model. The result showed that without sodium metabisulfite (control, when the initial level was high (105 CFU/ml, S. Typhimurium grew with a lag phase of 51.99±7.46 h and a growth rate of 0.01±0.002 log CFU.ml-1.h-1 on raw shrimps during storage at 8±2°C. When 1.5% (w/w sodium metabisulfite, a maximum level that often used to prevent melanosis, was added under the same condition, the number of S. Typhimurium was reduced for 5 log CFU/ml after 5 days, with a reduction rate of -0.03±0.001 log CFU.ml-1.h-1. This study indicated that Baranyi model can be used to predict the growth of S. Typhimurium on raw shrimp at low temperature, when sodium metabisulfite is absent. However, when sodium metabisulfite is present, at least 0.4% as found in this study, the reduction of S. Typhimurium can be predicted using a simple linear model.

Full Text Available The role of arsenic-safe drinking water and antioxidants in the management of arsenicosis patients were observed. Two hundred and fifty patients of arsenicosis from an arsenic-affected area of Bangladesh were included and divided into five groups based on the source of drinking water (green- or red-marked tube well and intake of antioxidants (vitamin A, C and E. Melanosis improved in 43 patients of the group who took arsenic-safe drinking water from green-marked tube well and antioxidants regularly. Patients of the group who took green-marked tube well water regularly but not the antioxidant showed improvement in melanosis in 22 cases. The respondents who were using red-marked tube well water and antioxidants, only two of them improved; and all other respondents either deteriorated or did not improve. The respondents who were using red-marked tube well water but not the antioxidant, none did show any improvement of their illness. The respondents who took antioxidants irregularly and had irregular intake of safe water, were not considered to compare the prognosis of skin lesions. Regarding keratosis, the respondents who took green-marked tube well water regularly and antioxidant regularly, 8 of them improved, 1 case didn’t change; while the respondents who took green-marked tube well water regularly but not the antioxidant, 8 cases didn’t improve much but majority of them remain unchanged. Among the respondents of other groups, keratosis deteriorated. This study suggests that both arsenic-safe drinking water and use of antioxidants gave good result in improvement of the arsenicosis.

Malignant melanoma of the oral cavity is rare, accounting for 1 to 8% of all malignant melanomas. The overall prognosis remains poor despite the available treatments such as radical surgery, adjuvant radiotherapy, chemotherapy and immunotherapy due to failure in early detection and tendency in early metastasis. The etiology of mucosal malignant melanoma remains unkown. However, there are few cases of malignant melanoma of the oral cavity reported in the literature, which might be related to preexisting melanosis and radiation treatment. A case with malignant melanoma developed on the same site after 6 years following irradiation for squamous cell carcinoma of the oral cavity is reported in this article

This study analyzed a total of 1482 arsenicosis patients living in 6 of 496 upzilas (sub-districts) of Bangladesh, who were identified through household screening and then confirmed by a trained medical team headed by medical officer. Melanosis was common (97%) among them but about two-thirds (68.7%) of the patients were suffering from keratosis. Average age was 36 years and average duration of arsenic symptoms was 3 (median) years. About 50% of the patients had been drinking tubewell water more than 24 years. Melanosis was significantly associated with younger patients (P = 0.031), shallower tubewell (P = 0.005), and complication of conjunctivitis (P < 0.001). Keratosis was also significantly associated with older age (P 0.022), shallower tubewell (P < 0.001), complication of conjunctivitis (P < 0.001), bronchitis (P < 0.001), loss of appetite (P < 0.001), and wasting (P < 0.001). Duration of arsenic symptoms was significantly associated with older age (P < 0.001), male (P = 0.002), married (P < 0.001), smoking (P 0.002), longer duration of consuming tubewell water (P < 0.001), complication of conjunctivitis (P = 0.002), loss of appetite (P < 0.001), wasting (P 0.006), and social problem faced having arsenicosis (P = 0.040). Multivariate odds ratio (OR) and 95% confidence interval (CI) indicated that keratosis (OR 2.00; 95% CI: 1.56-2.56) was significantly associated with longer duration of arsenic symptoms; loss of appetite (OR = 1.40; 95% CI: 1.12-1.74) was a significant complication for longer duration. Similarly smoking (OR = 1.33; 95% CI: 1.06-1.68) was positively associated with longer duration of arsenic symptom. These findings will help the policy makers of Bangladesh to understand about the factors that may affect the severity condition of the patients through prolongation of arsenic symptoms

Objective Xeroderma pigmentosum (XP) is a rare autosomal recessive disease caused by mutations in DNA repair genes. Clinical manifestations of XP include mild to extreme sensitivity to ultraviolet radiation resulting in inflammation and neoplasia in sun-exposed areas of the skin, mucous membranes, and ocular surfaces. This report describes the ocular manifestations of XP in patients systematically evaluated in the Clinical Center at the National Institutes of Health. Design Retrospective Observational Case Series Participants Eighty-seven participants, aged 1.3 to 63.4 years, referred to the National Eye Institute for examination from 1964 to 2011. Eighty-three had XP, 3 had XP/Cockayne Syndrome complex, and 1 had XP/trichothiodystrophy complex. Methods Complete, age- and developmental stage-appropriate ophthalmic examination. Main Outcome Measures Visual acuity; eyelid, ocular surface and lens pathology; tear film and tear production measures; and cytological analysis of conjunctival surface swabs. Results Of the 87 patients, 91% had at least one ocular abnormality. The most common abnormalities were conjunctivitis (51%), corneal neovascularization (44%), dry eye (38%), corneal scarring (26%), ectropion (25%), blepharitis (23%), conjunctival melanosis (20%), and cataracts (14%). Thirteen percent of patients had some degree of visual axis impingement and 5% had no light perception in one or both eyes. Ocular surface cancer or a history of ocular surface cancer was present in 10% of patients. Patients with an acute sunburning skin phenotype were less likely to develop conjunctival melanosis and ectropion but more likely to develop neoplastic ocular surface lesions than non-burning patients. Some patients also showed signs of limbal stem cell deficiency. Conclusions Our longitudinal study reports the ocular status of the largest group of XP patients systematically examined at one facility over an extended period of time.

Full Text Available Neonatal pustular eruption is a group of disorders characterized by various forms of pustulosis seen in first 4 weeks of life. Its presentation is often similar with some subtle differences, which can be further established by few simple laboratory aids, to arrive at a definite diagnosis. Given their ubiquitous presentation, it is sometimes difficult to differentiate among self-limiting, noninfectious, pustular dermatosis such as erythema toxicum neonatorum, transient neonatal pustular melanosis, miliaria pustulosa, etc., and potentially life threatening infections such as herpes simplex virus and varicella zoster virus infections. This review article tries to address the chronological, clinical, morphological, and histological differences among the various pustular eruptions in a newborn, in order to make it easier for a practicing dermatologist to diagnose and treat these similar looking but different entities of pustulation with a clear demarcation between the physiological benign pustular rashes and the infectious pustular lesions.

1991-01-01

At the faculties of dentistry in Chiang Mai, Thailand (CM), and Kuala Lumpur, Malaysia (KL), 234 and 233 consecutive out-patients were interviewed concerning tobacco and chewing habits and examined for the presence of oral melanin pigmentation. Tobacco was regularly used by 32% and 28% of the studied populations in CM and KL. Cigarette smoking was the predominant habit, but the chewing of betel and tea leaves (miang) and the smoking of banana leaf cigars (khi yo) was also registered. The genetically acquired pigmentation dominated. Although nearly all non-tobacco users in the Malay and Indian populations had oral melanin pigmentation, it was found that tobacco smokers had significantly more oral surfaces pigmented than non-tobacco users. Among Thais, the percentage of pigmented individuals was significantly higher among tobacco smokers. It was concluded that tobacco smoking stimulates oral melanocytes to a higher melanin production also in dark-skinned ethnic groups.

Full Text Available Melanocytic lesions of the conjunctiva represent a wide spectrum of tumors that include benign, premalignant, and malignant tumors. There are many ongoing arguments about the definition, classification, and therapeutic options of the conjunctival melanocytic tumors with many different suggestions. Conjunctival nevi are the most common melanocytic tumors and their risk of malignant transformation is less than1%. Primary acquired melanosis (PAM histopathologically includes various types of lesions from increased melanin pigmentation without melanocyte proliferation to melanoma in situ and is accepted as a clinical definition, so that a new classification is recommended which is based on more objective criteria than before. Although conjunctival melanoma is seen rarely, it is associated with a high mortality rate. Management of these tumors mainly involves surgery and adjuvant topical chemotherapy, cryotherapy, and radiation therapy that help improving the survival, however, new options are being investigated related to genetic and molecular researches.

Long-term exposure to arsenic has been associated with manifestation of skin lesions (melanosis/keratosis) and increased risk of internal cancers (lung/bladder). The objective of the study described here was to determine the relationship between exposure of arsenic through drinking groundwater and urinary arsenic excretion among adults > or =15 years of age living in Khairpur district, Pakistan. Total arsenic was determined in drinking groundwater and in spot urine samples of 465 randomly selected individuals through hydride generation-atomic absorption spectrometry. Spearman's rank correlation coefficient was calculated between arsenic in drinking groundwater and arsenic excreted in urine. The median arsenic concentration in drinking water was 2.1 microg/L (range: 0.1-350), and in urine was 28.5 microg/L (range: 0.1-848). Positive correlation was found between total arsenic in drinking water and in urine (r = .52, p arsenic may be used as a biomarker of arsenic exposure through drinking water.

Arsenic (As) poisoning has become a worldwide public health concern. The skin is quite sensitive to As and skin lesions are the most common and earliest nonmalignant effects associated to chronic As exposure. In 2005-2007, a survey was carried out on surface and groundwater arsenic contamination and relationships between As exposure via the drinking water and related adverse health effects (melanosis and keratosis) on villagers resides on the banks of Manchar lake, southern part of Sindh, Pakistan. We screened the population from arsenic-affected villages, 61 to 73% population were identified patients suffering from chronic arsenic toxicity. The effects of As toxicity via drinking water were estimated by biological samples (scalp hair and blood) of adults (males and females), have or have not skin problem (n = 187). The referent samples of both genders were also collected from the areas having low level of As ( 2 = 0.852 and 0.718) as compared to non-diseased subjects (R 2 = 0.573 and 0.351), respectively

Chemical and microbiological deteriorations are principal causes of quality loss of fish and fish products during handling, processing, and storage. Development of rancid odor and unpleasant flavor, changes of color and texture as well as lowering nutritional value in fish can be prevented by appropriate use of additives. Due to the potential health hazards of synthetic additives, natural products, especially antioxidants and antimicrobial agents, have been intensively examined as safe alternatives to synthetic compounds. Polyphenols (PP) are the natural antioxidants prevalent in fruits, vegetables, beverages (tea, wine, juices), plants, seaweeds, and some herbs and show antioxidative and antimicrobial activities in different fish and fish products. The use of phenolic compounds also appears to be a good alternative for sulphiting agent for retarding melanosis in crustaceans. Phenolic compounds have also been successfully employed as the processing aid for texture modification of fish mince and surimi. Thus, plant polyphenolic compounds can serve as potential additives for preventing quality deterioration or to retain the quality of fish and fish products.

The radiotherapy efficiency is still undervalued in the therapeutic taking charge of the malignant melanoma. Our series with its heterogeneity has authorized an only mono factorial analysis. The data in literature and our personal experience give a better efficiency of the strong unitary doses in term of local control. The accuracy of irradiation must allow to reduce the importance of after-effects that can be necessary to the local control and then to the survival. for the future, an increasing of of the applied unitary doses, by taking into account the localisation, the tumoral volume and the therapeutic objective, would allow to improve the efficiency of this treatment. In The particular indication of inoperable Dubreuilh melanosis, it could be an alternative to the surgery. The results of a complementary radiotherapy, after a radical surgery of secondary localisation are very encouraging. Its contribution in adjuvant treatment of recurrence or primitive lesions with high risks would deserve to be evaluated in the frame of well defined and randomized tests. (N.C.)

Lethal genes surviving by mosaicism: a possible explanation for sporadic birth defects involving the skin.

Science.gov (United States)

Happle, R

1987-04-01

A genetic concept is advanced to explain the origin of several sporadic syndromes characterized by a mosaic distribution of skin defects. It is postulated that these disorders are due to the action of a lethal gene surviving by mosaicism. The presence of the mutation in the zygote will lead to death of the embryo at an early stage of development. Cells bearing the mutation can survive only in a mosaic state, in close proximity with normal cells. The mosaic may arise either from a gametic half chromatid mutation or from an early somatic mutation. This concept of origin is proposed to apply to the Schimmelpenning-Feuerstein-Mims syndrome, the McCune-Albright syndrome, the Klippel-Trenaunay syndrome, the Sturge-Weber syndrome, and neurocutaneous melanosis. Moreover, this etiologic hypothesis may apply to two other birth defects that have recently been delineated, the Proteus syndrome (partial gigantism of hands or feet, hemihypertrophy, macrocephaly, linear papillomatous epidermal nevus, subcutaneous hemangiomas and lipomas, accelerated growth, and visceral anomalies), and the Delleman-Oorthuys syndrome (orbital cyst, porencephaly, periorbital appendages, and focal aplasia of the skin.

This study aimed to investigate the effect of chitosan-carvacrol coating with or without caprylic acid (CAP) on the quality of Pacific white shrimp (Litopenaeus vannamei) during 10days of iced storage. The result showed that chitosan-carvacrol coating significantly inhibited the increase in total aerobic plate count (TPC), pH and total volatile basic nitrogen content (TVB-N) of shrimp in comparison with the control. Chitosan-carvacrol coating also delayed the melanosis formation and changes of ΔE values, and improved the texture and sensory properties of shrimp. Moreover, incorporation of CAP potentiated the efficacy of chitosan-carvacrol coating in retarding the increase of TPC and TVB-N. Incorporation of CAP into chitosan-carvacrol coating also enabled the texture characteristics of shrimp to be retained greater degrees. These results suggested that chitosan-carvacrol coating may be promising to be used as active packaging for extending the shelf life, and incorporation of CAP may enhance the efficacy of the coating.

The presence of any age-related differences in gingival pigmentation associated with smoking, particularly in a young population, remains to be fully investigated. The purpose of this study was to determine the age-related differences in smoking gingival pigmentation. Gingival pigmentation was analyzed using the gingival melanosis record (GMR) and Hedin's classification with frontal oral photographs taken at 16 dental offices in Japan. Participants were categorized into 10-year age groups, and their baseline photographs were compared. In addition, to evaluate the effect of smoking cessation on gingival pigmentation, subjects were divided into a former smoker group (stopped smoking) and current smoker group. A total of 259 patients 19 to 79 years of age were analyzed. People in their 30s showed the most widespread gingival pigmentation. In addition, subjects in their 20s showed a weak effect of smoking cessation on gingival pigmentation. These findings suggested that the gingival pigmentation induced by smoking was more remarkable in young people than in middle-aged people. This information may be useful for anti-smoking education, especially among young populations with a high affinity for smoking.

Full Text Available [english] Introduction: Conjunctival melanoma is a relatively rare ocular malignancy with substantial associated morbidity and mortality. It can arise in previously unblemished and unpigmented regions (approximately 10% of cases, from a preexisting nevus (approximately 20% of cases, or from the flat, spreading pigmentation of primary acquired melanosis with atypia (60–70% of cases, actually called conjunctival melanocytic intraepithelial neoplasia (C-MIN with atypia (histopathologically more accurately term. Purpose: The authors describe an extremely rare case of malignant conjunctival melanoma, with a long evolution, in a young black woman. Results: Until now the patient has not shown any sign of relapse of this melanoma, after local excision.Conclusion: Conjunctival melanoma is a condition of concern because of its rarity and lethal potential. Advances in the understanding and management of this neoplasm have markedly reduced the mortality and possibly the morbidity associated with this malignancy. We observe that there are some cases of conjunctival melanoma that might be cured with only a local excision with posterior cryotherapy without more aggressive methods. The practice of narrative medicine brings new possibilities in the diagnosis and collection of classical history.

Full Text Available Background: Black spots are a major problem in commercial shrimp species and can have negative effects on shrimps' appearance, quality, shelf life, economic value, and product acceptance by consumers. This study was conducted to investigate the effect of orange peel extract on chemical and sensory qualities as well as black spots on Litopenaeus vannamei species of white farmed shrimp. Methods: Samples included treated shrimps at concentration of 150 g, orange peel extract for 30 minutes, and control shrimps. After storage for 10 days at 1 ± 4 °C, the samples’ chemical and sensory evaluations were performed with an interval of 5 days. Results: pH factors, peroxide value, and total volatile network (TVN of treated samples were significantly lower compared to those of the control samples (P < 0.05. There was no significant difference in the moisture content. Black spots did not appear in the treated sample until the end of refrigerated storage, but melanosis appeared in control shrimp 5 days after storage. Conclusion: The results showed that because of having antioxidant and antimicrobial activity, orange peel extract improved shrimps' chemical and sensory qualities and reduced their black spots in the refrigerator temperature.

Full Text Available Shisha is a water pipe that tobacco extract and fruit scented burnt using coal. It produces the smoke through the vessel and inhaled using a hose with good taste. The culture of shisha smoking is popular in Midle East country that curently has been also entering Indonesia. The side effect of shisha smoking habit is still very rare reported. Aim of this study is to describe the oral mucosa condition of shisha user. A preliminary observasional study was conducted at several sisha cafe at South Jakarta. Under informed consent, subject with habit of tobacco and shisha smoker were included. Sociodemographic data (age, gender, duration, frequency of smoking, salivary flow rate and oral mucosa changes were documented. Eighteen subjects were recruited into this study. Most of shisha smoker was also tobacco smoker. Shisha was more practiced by male at  age (15-24 years old. The oral mucosa changes such as keratosis, melanosis, leukoedema, coated tongue, gingivitis and xerostomia were found on subject with habit of tobacco smoking habit only or both shisha and tobacco smoking. In conclusion apparently the shisha smoking habit may casue oral mucosa changes almost the same with tobacco smoking habit

There are many textural elements that can be found in the human eye, including Fuchs’ crypts, Wolfflin nodules, pigment spots, contraction furrows and conjunctival melanosis. Although iris surface features have been well-studied in populations of European ancestry, the worldwide distribution of these traits is poorly understood. In this paper, we develop a new method of characterizing iris features from photographs of the iris. We then apply this method to a diverse sample of East Asian, European and South Asian ancestry. All five iris features showed significant differences in frequency between the three populations, indicating that iris features are largely population dependent. Although none of the features were correlated with each other in the East and South Asian groups, Fuchs’ crypts were significantly correlated with contraction furrows and pigment spots and contraction furrows were significantly associated with pigment spots in the European group. The genetic marker SEMA3A rs10235789 was significantly associated with Fuchs’ crypt grade in the European, East Asian and South Asian samples and a borderline association between TRAF3IP1 rs3739070 and contraction furrow grade was found in the European sample. The study of iris surface features in diverse populations may provide valuable information of forensic, biomedical and ophthalmological interest. PMID:26909168

The diagnostic yield in open access endoscopy has been evaluated which generally support the effectiveness and efficiency of open access endoscopy. With a few exceptions, diagnostic yield studies have not been performed in open access endoscopy for more specific conditions. Therefore, we conducted a study to determine the efficiency of open access endoscopy in the detection of microscopic colitis as compared to traditional referral via a gastroenterologist. A retrospective search of the pathology database at the University of Missouri for specimens from a local open access endoscopy center was conducted via SNOMED code using the terms: "microscopic", "lymphocytic", "collagenous", "spirochetosis", "focal active colitis", "melanosis coli" and "histopathologic" in the diagnosis line for the time period between January 1, 2004 and May 25, 2006. Specimens and colonoscopy reports were reviewed by a single pathologist. Of 266 consecutive patients with chronic diarrhea and normal colonoscopies, the number of patients with microscopic disease are as follows: Lymphocytic colitis (n = 12, 4.5%), collagenous colitis (n = 17, 6.4%), focal active colitis (n = 15, 5.6%), and spirochetosis (n = 2, 0.4%). The diagnostic yield of microscopic colitis in this study of an open access endoscopy center does not differ significantly from that seen in major medical centers. In terms of diagnostic yield, open access endoscopy appears to be as effective in diagnosing microscopic colitis.

It has been reported that chronic sennoside use is associated with the development of melanosis coli, colonic adenoma, and/or carcinomas. In this study, we investigated the immunological changes in the colon and skin after the administration of senna. In this study, we investigated the colon and epidermis of C57/BL6j mice after a single administration of 10 mg/kg of senna [Cassia angustifolia (Caesalpiniaceae); 3, 6, 12, and 24 h after administration] and after repeated once per week administrations (on days 3, 5, 7, 14, and 21 of administration). The LD50 and ED50 of senna used in this experiment were 165 mg/kg and 13 g/kg, respectively. We demonstrated that the DOPA-positive cells in the colon increased at 12 h after single administration and were further increased from at 5-28 d after repeated administration. We also studied the physiological changes of the small intestine using the charcoal meal test. We found that there was a tendency for peristalsis to be inhibited after repeated senna administration. In the epidermis, we investigated the number of Langerhans cells, because they are important immune cells of the skin. The number of these cells decreased, especially after repeated administration. The present findings suggested that it is necessary to pay attention to not only the intestine but also the skin, during long-term senna treatment.

The color of normal skin and of oral mucosa is not determined by the number of melanocytes in the epithelium but rather by their melanogenic activity. Pigmented biopolymers or melanins are synthesized in melanosomes. Tyrosinase is the critical enzyme in the biosynthesis of both brown/black eumelanin and yellow/red pheomelanin. The number of the melanosomes within the melanocytes, the type of melanin within the melanosomes, and the efficacy of the transfer of melanosomes from the melanocytes to the neighboring keratinocytes all play an important role in tissue pigmentation. Melanin production is regulated by locally produced factors including proopiomelanocortin and its derivative peptides, particularly alpha-melanocyte-stimulating hormone (α-MSH), melanocortin 1 receptor (MC1R), adrenergic and cholinergic agents, growth factors, cytokines, and nitric oxide. Both eumelanin and pheomelanin can be produced by the same melanocytes, and the proportion of the two melanin types is influenced by the degree of functional activity of the α-MSH/MC1R intracellular pathway. The cause of HIV oral melanosis is not fully understood but may be associated with HIV-induced cytokine dysregulation, with the medications commonly prescribed to HIV-seropositive persons, and with adrenocortical dysfunction, which is not uncommon in HIV-seropositive subjects with AIDS. The purpose of this article is to discuss some aspects of melanocyte biology and HIV-associated oral melanin hyperpigmentation.

Full Text Available Constipation is one of themost common chronic gastrointestinal problems. The estimated incidence of constipation in the United States is3% to 19% in general population.1,2 Patientswith head injuries, spinal cord injuries, pelvic fractures, lower extremity fractures ormultiple traumas require a long-term bed rest, during which the incidence of constipation reached as high as 50%.3,4 Constipation always brings inconvenience and tremendous suffering to patientsand strongly influences the recovery from primary disease. Irritants or lubricants can relieve the symptoms, but long-term application of them may lead to side effects like melanosis coli5 and cathartic colon6. The absorption of fat soluble vitamins is also affected.7 Polyethylene glycol 4000 (trade name: Forlax®, a long chain polymer with a high molecular weight, can conjugate withwater molecule through hydrogen bond to increase the water content and volume of stools, thereby, facilitate bowelmovement and defecation.8,9 It is neither absorbed nor metabolized in the digestive tract, hence it is highly safe and well tolerable. Thus, long-term medication of polyethylene glycol 4000 is conducive to the reconstruction of normal defecation pattern. Therefore, polyethylene glycol 4000 is now being widely used as the mainstay adult chronic functional constipation management.10,11 The aim of this study was to verify the efficacy and safety of polyethylene glycol 4000 on adult functional constipation of posttraumatic bedridden patients.

Full Text Available To understand the role of vitamin E in the treatment of arsenical melanosis and keratosis, the buccal cells of 19 patients, 14 arsenic exposed controls and 13 healthy volunteers were collected for the estimation of vitamin E both before and after supplementation with vitamin E (200 IU, caplet daily orally for 20 weeks. The vitamin E levels in the buccal cells of patients were significantly low in comparison to healthy volunteers (healthy vs patients: 17.2 ± 4.4 vs 12.3 ± 6.1 mg/mg of protein; p=0.012. These low level of vitamin E in patients returned toward normal levels following supplementation with vitamin E for 20 weeks (p=0.044. The vitamin E levels in serum of patients were also low (healthy vs patients: 18.9 ± 4.4 vs 10.2 ± 2.6 mg/mL; p=0.000. Supplementation with vitamin E overcomed the low levels of vitamin E in serum. The cholesterol levels in buccal cells and serum of patients were significantly low in comparison to healthy volunteers (buccal cells of healthy vs patients: 24.5 ± 14.1 vs 10.3 ± 9.8 mg/mg of protein; p=0.005; serum of healthy vs patients: 153.5 ± 22.8 vs 125.3 ± 37.0 mg/dL; p=0.012. After supplementation of vitamin E, there was no significant change in cholesterol levels in both buccal cells and serum of patients.

To determine the characteristics of, prevalence of, and risk factors for corneal pigmentation (CP) in Pugs. Prospective cross-sectional study. 295 Pugs > 16 weeks old. Ophthalmic examination of the anterior segment of each eye was performed, including determination of tear film characteristics (Schirmer tear test and tear film breakup time) and corneal sensitivity. Digital photographs of the head and each eye were obtained. Corneal pigmentation of eyes was graded as absent, very mild, mild, moderate, or severe. Signalment and medical history information and American Kennel Club registration status were recorded. Results-CP was detected in at least 1 eye of 243 of the 295 (82.4%) Pugs; CP was typically very mild or mild. Detection of CP was not significantly associated with coat color, age, eyelid conformation, or tear film characteristics but was significantly associated with sex of dogs. The severity of CP was not significantly associated with American Kennel Club registration status or age, but was significantly associated with sex, tear film characteristics, and coat color. Iris hypoplasia was detected in 72.1% of the Pugs. Iris-to-iris persistent pupillary membranes were detected in 85.3% of the Pugs. Prevalence of CP in Pugs in this study was high. Unexpectedly high prevalences of iris hypoplasia and persistent pupillary membranes were also identified. The condition identified in these Pugs was a pigmentary keratopathy, rather than pigmentary keratitis or corneal melanosis. This condition may have a genetic basis, and further studies are warranted to determine etiology.

Irradiation of carps at 200 krad followed by storage at 5-6degC extended the shelf-life to 21 days, but the problem of Salmonella appeared to be associated with such a product. This problem was overcome by blanching carps for 3 minutes followed by irradiation at 300 krad. Such products were acceptable up to 4 weeks if stored at 5-6degC and to 7 weeks if stored at 2degC. Spicing was useful in masking radiation induced off-flavour (rancid) in hilsha. Heat (60-70degC) treatment (1 hour) of spiced hilsha followed by irradiation at 200 krad extended the refrigerated (4-6degC) storage life to at least 44 days. The problem of Salmonella in hilsha was eliminated by blanching for 3 minutes, followed by irradiation at 200 krad. Blanching was essential to prevent melanosis in shrimps. Both blanching (3 minutes at 100degC) and irradiation at 200 krad extended the shelf-life of shrimps to 8 weeks at 2degC. Such a product was free from Salmonella. Irradiation of mackerel at 200 krad extended shelf-life to 4 weeks at 2degC. Blanching for 2 minutes prior to irradiation at 200 krad extended shel-life of mackerel to 10 weeks at 2degC; the problem of Salmonella was also eliminated by such a treatment. Therefore, irradiation of fish in Bangladesh for shelf-life extension at ice storage appears to have a great commercial scope

Full Text Available Introduction: Oral health reflects overall well-being for the elderly population. Compromised oral health may be a risk factor for systemic diseases commonly occurring in old age. Oral health evaluation should be an integral part of the physical examination, and dentistry is essential to qualify geriatric patient care. Aim: To determine the prevalence of oral soft tissue lesions and systemic diseases in institutionalized geriatric population in North India. Materials and Methods: Geriatric patients were clinically evaluated using a standard questionnaire and assessed for known medical illnesses and prevalence of oral soft tissue lesions. Four hundred patients (71% males and 29% females with age ranging from 60 to 100 years were considered in the study group. Twenty-two (33.8% patients were edentulous and seven patients (10.8% were denture wearers. Forty-four (67.69% patients reported with tobacco habits. Results: Most prevalent medical illness reported was diminished vision (15.5%, followed by hypertension (10% and diabetes mellitus (6.25%. Several oral soft tissue lesions were reported among the study population. The most prevalent lesions were leukoplakia (12%, smoker′s melanosis (10%, smoker′s palate (9%, pigmentation on tongue (6%, frictional keratosis (5%, lichen planus (3%, denture stomatitis (2.5%, aphthous ulcers (2%, angular chelitis (1.5%, oral submucous fibrosis (1.5%, melanotic macule (1.5%, candidiasis (1.5%, irritation fibroma (1%, geographic tongue (1%, median rhomboid glossitis (1%, and traumatic ulcer (1%. Conclusion: The findings observed in this population are important and can have a determinant effect on the overall quality of life in this population. This information is a crucial prerequisite for health awareness programs involving the community health workers, oral physicians, and medical professionals.

In Pakistan cirrhosis has reached alarming proportions due to spread of HCV and HBV viruses. Some of the oral manifestations of cirrhosis have been found to exhibit geographically variability. There is no research available on the oral health of these patients in Pakistan and their specific oral problems are not known. This study examined a cohort of cirrhotic patients admitted at Shaikh Zayed hospital Lahore to assess their oral health status and needs. Materials and methods: Thirty consecutive patients admitted with diagnosis of cirrhosis were examined for oral health status. Extra oral examination included any visible lesions or abnormalities on the face, head or neck region, lymph node enlargement and TMJ dysfunction. Intra oral examination included measurement of caries (DMFT) and periodontal disease level (CPITN), oral mucosal lesions, prosthetic status and prosthetic needs of the patients. All findings were recorded on the standard WHO oral health survey form. The oral health of this cohort was poor compared to the general population. Xerostomia (20%), papillary atrophy (100%), oral Melanosis (90%), petechieal hemorrhages (26%) and glossitis (53%) were found prevalent in the sample. Two females had oral lichen planus and one of the patients had oral ulceration. DMFT score (Mean=5.7) was not different from national average (Mean=8.02). Periodontal disease was more severe than general population. Less than 21% of the sample wore prostheses and over 50% needed one. TMJ dysfunction was common but fewer patient complained of the condition that the number of patients with clinical signs. Conclusions: Oral health of cirrhotic population is worse than general population and they have significant oral health needs. Further research is required to investigate this relationship. Effective oral health education of patients and physicians is required to reduce the burden of oral disease thus improving quality of life for these patients. (author)

Arsenic (As) poisoning has become a worldwide public health concern. The skin is quite sensitive to As and skin lesions are the most common and earliest nonmalignant effects associated to chronic As exposure. In 2005-2007, a survey was carried out on surface and groundwater arsenic contamination and relationships between As exposure via the drinking water and related adverse health effects (melanosis and keratosis) on villagers resides on the banks of Manchar lake, southern part of Sindh, Pakistan. We screened the population from arsenic-affected villages, 61 to 73% population were identified patients suffering from chronic arsenic toxicity. The effects of As toxicity via drinking water were estimated by biological samples (scalp hair and blood) of adults (males and females), have or have not skin problem (n = 187). The referent samples of both genders were also collected from the areas having low level of As (< 10 {mu}g/L) in drinking water (n = 121). Arsenic concentration in drinking water and biological samples were analyzed using electrothermal atomic absorption spectrometry. The range of arsenic concentrations in lake surface water was 35.2-158 {mu}g/L, which is 3-15 folds higher than World Health Organization [WHO, 2004. Guidelines for drinking-water quality third ed., WHO Geneva Switzerland.]. It was observed that As concentration in the scalp hair and blood samples were above the range of permissible values 0.034-0.319 {mu}g As/g for hair and < 0.5-4.2 {mu}g/L for blood. The linear regressions showed good correlations between arsenic concentrations in water versus hair and blood samples of exposed skin diseased subjects (R{sup 2} = 0.852 and 0.718) as compared to non-diseased subjects (R{sup 2} = 0.573 and 0.351), respectively.

Few studies have been conducted in the Saudi population on oral mucosal lesions. The purpose of this study was to evaluate the type and extent of oral lesions in a study among dental patients at a college of dentistry in Saudi Arabia. Over a 3-year period, 2552 dental outpatients were interviewed and investigated clinically for the presence of oral mucosal conditions. A thorough oral clinical examination was performed, including a radiographic examination. The diagnosis was confirmed histopathologically when necessary. Of 383 (15.0%) patients found to have oral mucosal lesions, females constituted 57.7% (n=221) and males 42.3% (n=162). The age range of the patients was between 15 to 73 years with a mean age of 38.2 years. The most commonly affected age group was 31 to 40 years, which comprised 21.4% (n=82) of all affected individuals. The least affected age group were individuals older than 61 years. The most common lesion was Fordyce granules (3.8%; n=98), followed by leukoedema (3.4%; n=86) and traumatic lesions (ulcer, erosion) in 1.9% (n=48). Tongue abnormalities were present in 4.0% (n=101) of all oral conditions observed, ranging from 1.4% (n=36) for fissured tongue to 0.1% (n=2) for bifid tongue. Other findings detected were torous platinus (1.3%; n=34), mandibular tori (0.1%; n=2) aphthous ulcer (0.4%; n=10), herpes simplex (0.3%; n=7), frictional hyperkeratosis (0.9%; n=23), melanosis (0.6%; n=14), lichen planus (0.3%; n=9) and nicotinic stomatitis (0.5%; n=13). The findings of this study provide information on the types and prevalence of oral lesions among Saudi dental patients. This provides baseline data for future studies about the prevalence of oral lesions in the general population. (author)

A significant proportion of groundwater in south Asia is contaminated with arsenic. Pakistan has low levels of arsenic in groundwater compared with China, Bangladesh and India. A representative multi-stage cluster survey conducted among 3874 persons ≥15 years of age to determine the prevalence of arsenic skin lesions, its relation with arsenic levels and cumulative arsenic dose in drinking water in a rural district (population: 1.82 million) in Pakistan. Spot-urine arsenic levels were compared among individuals with and without arsenic skin lesions. In addition, the relation of age, body mass index, smoking status with arsenic skin lesions was determined. The geographical distribution of the skin lesions and arsenic-contaminated wells in the district were ascertained using global positioning system. The total arsenic, inorganic and organic forms, in water and spot-urine samples were determined by atomic absorption spectrophotometry. The prevalence of skin lesions of arsenic was estimated for complex survey design, using surveyfreq and surveylogistic options of SAS 9.1 software.The prevalence of definitive cases i.e. hyperkeratosis of both palms and soles, was 3.4 per 1000 and suspected cases i.e. any sign of arsenic skin lesions (melanosis and/or keratosis), were 13.0 per 1000 among ≥15-year-old persons in the district. Cumulative arsenic exposure (dose) was calculated from levels of arsenic in water and duration of use of current drinking water source. Prevalence of skin lesions increases with cumulative arsenic exposure (dose) in drinking water and arsenic levels in urine. Skin lesions were 2.5-fold among individuals with BMI 2 . Geographically, more arsenic-contaminated wells and skin lesions were alongside Indus River, suggests a strong link between arsenic contamination of groundwater with proximity to river.This is the first reported epidemiological and clinical evidence of arsenic skin lesions due to groundwater in Pakistan.

Full Text Available Food additives are redefined in European legislation (EC Regulation No. 1333/2008. Sulphur dioxide (E220 and sulphite (E221- E228 are widely used in food processing as preservatives because they slow down bacterial growth on foods and prevent oxidation or browning developing on shrimp and lobster. Shellfish processors, farmers and fishermen have long used sulfiting agents in a variety of species of warm and coldwater crustaceans as a treatment to prevent prawns and shrimps melanosis (blackspot, which is a natural process that makes the shell black after harvesting caused by Polyphenoloxidase enzyme systems which remain active during refrigeration or ice storage. Sulfite-induced hypersensitivity is the most well-established adverse response in humans to this food additive. In the present study the presence of sulfites in different frozen and thawed shrimp and prawn species belonging to Penaeoidea superfamily has been evaluated by the Monier-Williams procedure, in order to carry out a risk assessment and evaluate the levels of consumer exposure to this class of additives from these fish products. In addition to assessing and monitoring the correct use of the additive, according to the limits imposed by the European regulations, the correct consumer information on labels was also evaluated. Analysis were performed on both whole shrimp (shell on and inedible parts (head and peeled shell. Sulphites concentration in frozen samples (expressed as SO2 mg/kg mean value±S.D. was 214±17.43 for head on shell on shrimps; 170.73±14.99 for shell on headless shrimps; 112.90±27.55 for peeled and deveined shrimps. Thawed shrimps were purchased at mass retailers channel and local fish markets and local seafood retailers and purveyors: for these samples, all head on shell on, the sulphites concentration (expressed as SO2 mg/kg mean value±S.D. was 160.05±26.15 and 292.54±146.04, respectively. Non-edible parts showed, in all samples, much higher concentrations.

To document the ocular manifestations of xeroderma pigmentosum (XP), presenting via the United Kingdom (UK) XP service, and to analyze the correlations between XP genotype and ophthalmic phenotype. Prospective observational case series. Eighty-nine patients seen by the UK Nationally Commissioned XP Service, from April 2010 to December 2014, with a genetically confirmed diagnosis of XP. Patients underwent a full ophthalmic examination at each visit. Clinical features from both eyes were recorded on a standard proforma. The most recent assessments were analyzed. A 2-tailed Fisher exact test was used to assess for differences in ocular features between patients in XP subgroups with impaired transcription coupled nucleotide excision repair (TC-NER) (category 1: XP-A, B, D, F, and G) and preserved TC-NER (category 2: XP-C, E, and V). Lid and periocular abnormalities, ocular surface pathologies, neuro-ophthalmologic abnormalities, lens and retinal abnormalities, and visual acuity (VA). Ninety-three percent of XP patients in our cohort had ocular involvement, with 65% describing photophobia. The most common abnormalities were in the periocular skin and ocular surface, including interpalpebral conjunctival melanosis (44%) and conjunctival injection (43%). Eleven percent of patients had required treatment for periocular cancers and 2% for ocular surface cancers. The most common neuro-ophthalmologic finding was minimal pupillary reaction to light (25%). Patients in category 2 had significantly more ocular surface abnormalities than patients in category 1, including a greater proportion of conjunctival injection (P = 0.003), conjunctival corkscrew vessels (P < 0.001), corneal scarring (P = 0.01) and pingueculae under the age of 50 (P = 0.02). Meanwhile, patients in category 1 had a higher proportion of poorly reactive pupils (P < 0.001) and abnormal ocular movements (P = 0.03) compared with those in category 2. Five patients (6%) presented to ophthalmologists with ocular

Sociedad llegó a constituirse en un poderoso impulsor de varias de las ciencias básicas a mediados del siglo XX, a tal punto que muchos de sus integrantes, además de haber incrementado significativamente su producción científica creyeron necesario organizar sociedades especializadas ya en entomología o en antropología o en botánica, lo mismo que en diversas ramas de la medicina. Si bien las actividades de la Sociedad de Biología decayeron a partir de 1959, tal situación debe entenderse como el fenómeno natural de una madre nutricia que desfallece al dar a luz múltiples productos que en forma independiente siguen sus ideales y principios.

Y qué no decir de las otras contribuciones a la ciencia y a la medicina que se deben recordar, no por desconocidas, sino porque tienen la importancia que hoy quiere destacar la Academia al otorgar la máxima distinción al doctor Ordóñez. En cuanto a investigaciones, la primera y muy notable, el hallazgo de una nueva modalidad de la contracción muscular, la prosténica, sobre la cual nos hablará más tarde, hallazgo que hizo cuando apenas cursaba el tercer año de medicina, trabajando a la usanza de la época, como preparador del laboratorio de fisiología, cargo al cual se llegaba por riguroso concurso entre los estudiantes.

Otras muestras de sus investigaciones fueron los estudios sobre resistencia del sistema nervioso central a la anoxia, el hallazgo de un nuevo tipo de melanosis, la melanosis de Ordóñez registrada así en el Diccionario de Jablonsky, los problemas de salud enalturas y sus numerosas publicaciones las más sobre distintos aspectos de las enfermedades cardiovasculares, aparecidas tanto en revistas locales como en aquellas de reconocida importancia internacional por ejemplo Comptes Rendu des Séances de le Societé de Biologie y los Archives des Maladies du Coeur. Sería imposible detallarlas todas.

Fifty districts of Bangladesh and 9 districts in West Bengal, India have arsenic levels in groundwater above the World Health Organization's maximum permissible limit of 50 microg/L. The area and population of 50 districts of Bangladesh and 9 districts in West Bengal are 118,849 km2 and 104.9 million and 38,865 km2 and 42.7 million, respectively. Our current data show arsenic levels above 50 microg/ L in 2000 villages, 178 police stations of 50 affected districts in Bangladesh and 2600 villages, 74 police stations/blocks of 9 affected districts in West Bengal. We have so far analyzed 34,000 and 101,934 hand tube-well water samples from Bangladesh and West Bengal respectively by FI-HG-AAS of which 56% and 52%, respectively, contained arsenic above 10 microg/L and 37% and 25% arsenic above 50 microg/L. In our preliminary study 18,000 persons in Bangladesh and 86,000 persons in West Bengal were clinically examined in arsenic-affected districts. Of them, 3695 (20.6% including 6.11% children) in Bangladesh and 8500 (9.8% including 1.7% children) in West Bengal had arsenical dermatological features. Symptoms of chronic arsenic toxicity developed insidiously after 6 months to 2 years or more of exposure. The time of onset depends on the concentration of arsenic in the drinking water, volume of intake, and the health and nutritional status of individuals. Major dermatological signs are diffuse or spotted melanosis, leucomelanosis, and keratosis. Chronic arsenicosis is a multisystem disorder. Apart from generalized weakness, appetite and weight loss, and anemia, our patients had symptoms relating to involvement of the lungs, gastrointestinal system, liver, spleen, genitourinary system, hemopoietic system, eyes, nervous system, and cardiovascular system. We found evidence of arsenic neuropathy in 37.3% (154 of 413 cases) in one group and 86.8% (33 of 38 cases) in another. Most of these cases had mild and predominantly sensory neuropathy.

-groups. RESULTS: The total number of diagnoses of dermatosis was 280 with an average number of 3. 73/ per elderly person and 32 different types of dermatosis: were found. The prevalence of the dermatosis most often found was respectively: melanosis (53.3%, seborrheic keratosis (46.6%, onychomycosis (37.3%, nevus (33.3%, senile purpura (29.3%, xerosis (14.6%, scabies (12.0% and malignant neoplasm (1.3%. The distribution of dermatosis was 70% (CI95%: 59% to 81% higher in the female population than in the male. CONCLUSION: Notwithstanding the small number of cases, these data are compatible with the few reports available in literature. This study of prevalence defined the distribution of dermatosis in a fraction of the elderly population. However the aggregate data of subsequent casuistries may provide the more precise information whose relevance is undeniable in the orientation of individual and collective future health measures.

The incidence of cutaneous melanoma has rapidly increased in the white population over the last decades. It has been estimated that the incidence doubles world-wide every 10 years. Different risk factors have been identified, including immunosuppression. The aim of our study-was to determine the relative risk of developing melanoma in the organ transplant population and the clinical and histological features of their melanomas. This retrospective study was conducted with the collaboration of 9 University Hospital Centers: Besançon, Brest, Caen, Dijon, Lille, Lyon, Nantes, Paris (Pitié-Salpétrière) and Rennes. A questionnaire was sent to the different departments of dermatology of these hospitals to obtain information on patients who had presented a melanoma after a transplantation between 1971 and 1997. During this period, there were 12,477 organ transplant recipients in the transplantation units of these 9 hospitals. Average follow-up for these patients was about 5 years and the average duration of immunosuppressive therapy was about 4.5 years. Among 12,477 organ transplant recipients, we found 17 cases of melanoma but no data could be obtain on one case: 14 occurred in renal transplant recipients and 3 in cardiac transplant recipients. Clinical and histological data were only available in 16 patients. The average time between transplantation and diagnosis of melanoma was 63 months, but it was 5 times shorter for 2 patients who had a past history of melanoma before transplantation. Two patients had a mucosal melanoma; for the cutaneous melanomas, 2 appeared on Dubreuilh melanosis, 2 were in situ melanomas, 7 were superficial spreading melanomas and 3 were nodular melanomas. The histological review of 11 cutaneous melanomas revealed a precursor nevus in 6 cases and a weak or no stroma reaction in 7/7 cases. Complete excision of the melanoma was performed in all patients except one with anorectal melanoma. Four patients died of visceral metastasis within a mean
