    Full Text Available BACKGROUND: Internal malignancies are accompanied by various skin changes which may be specific infiltrates or non-specific changes. This study is aimed at determining the frequency of such changes in malignant disease treatment center attendees in India. METHODS: A study of 300 confirmed cases of internal malignancy at a malignant disease treatment center was undertaken to evaluate these skin changes. Specific infiltrates were confirmed by histopathology. Statistical methods were employed to calculate significance in non-specific lesions by comparing with 300 controls not suffering from internal malignancy. RESULTS: Skin changes were present in 82 (27.3%. Cutaneous metastases were found in 19 (6.3%; non-contiguous in 5 (1.6%; contiguous in 14 (4.3%. Non-specific skin lesions numbered 74 (11.6% in 52 patients. Statistically significant non-specific skin changes were acquired ichthyosis, herpes zoster and generalized pruritus. CONCLUSION: Metastases usually occurred late in internal malignancy (17, 5.6% except in a case each of histiocytic lymphoma and non-Hodgkin′s lymphoma (2, 0.7% where the lesions preceded malignancy by 3 months and 1 month respectively. Contiguous nodules were a marker of relapse after surgery in 3 (1%.

    A review was made on 412 cases of postirradiation skin malignancies reported in Japan up to March 1988. The ratio of male to female was 2:1. Histologically, squamous cell carcinoma occupied 60% of all cases. The incidence of sarcoma has recently been increased. Sixty percent of all skin malignancies resulted from irradiation for benign diseases. Radiotherapy has recently become the treatment of choice for malignancy. The incidence of malignancy resulting from occupational exposure has remained unchanged. The latency period before the development of radiation-induced malignancy varied in the following order with cause or primary disease: occupation>benign tumors>malignant tumors; and it varied with histology in the following order: basal cell epithelioma>squamous cell carcinoma>sarcoma. Malignant tumors treated with large doses of high energy photon beams were likely to develop sarcomas in a relatively short latency period of time. (N.K.).

    Reports of an ageing population, increasing incidence of malignancy and improved treatments mean that dentists may have an increasing number of patients with, or who have recovered from, a malignancy. Dental professionals are expected to have an understanding of this important disease group so that appropriate dental care can be provided safely. In this first of three articles, we shall describe the important epidemiological and clinical features of the commonest malignancies in the United Kingdom. Dentists should understand the clinical implications of a patient with, or recovering from, a malignancy. This article gives a summary of the relevant features of the commonest malignancies.

    Because of the depletion of ozone in the stratosphere due to chlorofluorocarbons, the screening effect of this ozone layer on ultraviolet radiation (especially the so-called UV-B component) is reduced. This paper describes the impact of increased UV radiation on the human skin. Because of the 'ozone-hole', a distinct increase in the rate of skin cancer is to be expected which will affect all living beings but most of all man - an indirect consequence of the climate development. What makes the increased intensity of UV-B radiation so harmful is the fact that light-induced skin damage accumulates for the period of the life-time of the individual and cannot be reversed. A further thinning of stratospheric ozone would let through, in addition, the more short-waved ('harder') UV-C radiation. The latter, though clinically not significant currently, would then account for a further increase in the rate of malignant skin disease world-wide. (orig.) [de

    Common benign gynaecological diseases, such as leiomyoma, adenomyosis, endometriosis, and mature teratoma, rarely undergo malignant transformation. Benign transformations that may mimic malignancy include benign metastasizing leiomyoma, massive ovarian oedema, decidualization of endometrioma, and rupture of mature teratoma. The aim of this review is to provide a contemporary overview of imaging findings in malignant and apparent malignant transformation of benign gynaecological disease.

    Cutaneous manifestations of myeloid malignancies are common and have a broad range of presentations. These skin findings are classified as specific, due to direct infiltration by malignant hematopoietic cells, or non-specific. Early recognition and diagnosis can have significant clinical implications, as skin manifestations may be the first indication of underlying hematologic malignancy, can reflect the immune status and stage of disease, and cutaneous reactions may occur from conventional and targeted agents used to treat myeloid disease. In addition, infections with cutaneous involvement are common in immunocompromised patients with myeloid disease. Given the varying presentations, dermatologic findings associated with myeloid malignancies can pose diagnostic challenges for hematologists and dermatologists. In this clinical review intended for the practicing hematologist/oncologist, we discuss the presentation, diagnosis, treatment, and prognostic value of the most common cutaneous manifestations associated with myeloid malignancies using illustrative macro- and microscopic figures and with a special emphasis on practical considerations.

    Tobacco smoking is a serious and preventable health hazard that can cause or exacerbate a number of diseases and shorten life expectancy, but the role of smoking as an etiologic factor in the development of skin disease is largely unknown. Although epidemiological evidence is sparse, findings...... suggest that tobacco smoking is a contributing factor in systemic lupus erythematosus, psoriasis, palmoplantar pustulosis, cutaneous squamous cell carcinoma, hidradenitis suppurativa, and genital warts. In contrast, smoking may confer some protective effects and mitigate other skin diseases, notably...... pemphigus vulgaris, pyoderma gangrenosum, aphthous ulcers, and Behçet's disease. Various degenerative dermatologic conditions are also impacted by smoking, such as skin wrinkling and dysregulated wound healing, which can result in post-surgical complications and delayed or even arrested healing of chronic...

  14. Malignant diseases as suicidal motives

    Directory of Open Access Journals (Sweden)

    Bogdanović Ljiljana

    2007-01-01

    Full Text Available Introduction Suicide is a conscious and intentional destruction of one’s own life, which occurs as a result of mutual influence of a person’s disposition and motives (facts inspiring the commitment of suicide. It is well known that various diseases, including malignancies, could be important and in some cases the only motive for committing suicide. Objective The purpose of the study was to analyze in detail suicides of persons whose only motive was an established malignant disease. Method The analysis was performed using the autopsy material of the Institute of Forensic Medicine, School of Medicine, University of Belgrade, during the period from 1990 to 2004. The reports on performed medico-legal autopsies were used, as well as history data obtained from the family members of suicidal persons, investigation reports and the available medical documents. Results In 1931 cases there was established suicidal nature of a violent death. Neoplasms were the suicidal motive in 37 persons (1.9%. The basic characteristics of the analyzed sample were predominance of males (26:11, ratio 2.4:1, the age of over 70 years and the highest incidence of malignant lung and breast tumors. Almost all cases were the persons who underwent treatment for malignant neoplasms over a longer period of time. During 19 autopsies (51.3% out of 37, a progressive phase of malignancy was established, i.e. metastases. The data on prior oral announcement of suicide intention were obtained for 70.3% (26 cases, and on previous suicidal attempts only for 13.5% (5 cases. In the majority of cases (78.4% the place of committed suicide was the person’s home. In 16 cases (43.2% the suicide was committed with a firearm. Hanging as a manner of destroying one’s own life was chosen by 12 persons (32.4%, while other ways were less frequently used. Conclusion Although malignancies were not present with high incidence as a suicidal motive in our analyzed sample, such cases require particular

    Seven cases of radiation-induced malignant tumors and 60 cases of chronic radiation damage of skin are reported. Severe hyperplasia, false epitheliomatoid hyperpiasia and atypical proliferation of epithelia and atypical proliferation of fibrohistocytes were the main changes found in chronic radiation damage of skin. The development of malignant tumors from chronic radiation damage of skin can be divided into 4 periods: necrotic and degenerative change period, benign proliferative period, atypical proliferative period and malignant change period. The incidence of hyperplastic changes of skin is related to the time elapse after irradiation and the integrated dose of radiation. The longer the duration after irradiation and the larger the integrated dose are, the higher will be the incidence of hyperplastic changes

    Full Text Available Malignant melanoma is a kind of skin cancer that begins in melanocytes. It can influence on the skin only, or it may expand to the bones and organs. It is less common, but more serious and aggressive than other types of skin cancer. Malignant Melanoma can happen anywhere on the skin, but it is widespread in certain locations such as the legs in women, the back and chest in men, the face, the neck, mouth, eyes, and genitals. In this paper, a proposed algorithm is designed for diagnosing malignant melanoma types by using digital image processing techniques. The algorithm consists of four steps: preprocessing, separation, features extraction, and diagnosis. A neural network (NN used to diagnosis malignant melanoma types. The total accuracy of the neural network was 100% for training and 93% for testing. The evaluation of the algorithm is done by using sensitivity, specificity, and accuracy. The sensitivity of NN in diagnosing malignant melanoma types was 95.6%, while the specificity was 92.2% and the accuracy was 93.9%. The experimental results are acceptable.

    Blood films from 41 cases of coeliac disease complicated by malignancy were examined and evidence of hyposplenism found in 12 cases (29%). This is similar to the proportion of adult coeliacs without malignancy who have hypoplenism and it is concluded that impaired splenic function is not associated with the development of malignancy in coeliac disease.

    2017-09-18

    Melanomas usually present as oval lesions in which the borders may be irregular. Other morphological features of melanoma include clinical asymmetry, variable color, diameter greater than 6 mm and evolving lesions. Two males whose melanoma in situ presented as linear skin lesions are described and cutaneous malignancies that may appear linear in morphology are summarized in this report. A medical literature search engine, PubMed, was used to search the following terms: cancer, cutaneous, in situ, linear, malignant, malignant melanoma, melanoma in situ, neoplasm, and skin. The 25 papers that were generated by the search and their references, were reviewed; 10 papers were selected for inclusion. The cancer of the skin typically presents as round lesions. However, basal cell carcinoma and squamous cell carcinoma may arise from primary skin conditions or benign skin neoplasms such as linear epidermal nevus and linear porokeratosis. In addition, linear tumors such as basal cell carcinoma can occur. The development of linear cutaneous neoplasms may occur secondary to skin tension line or embryonal growth patterns (as reflected by the lines of Langer and lines of Blaschko) or exogenous factors such as prior radiation therapy. Cutaneous neoplasms and specifically melanoma in situ can be added to the list of linear skin lesions.

    Full Text Available BACKGROUND Skin cancer is the most common form of cancer globally accounting for at least 40% of cases. It is especially common among people with light skin. Non-melanoma skin cancers, about 80% are basal cell cancers and 20% squamous cell cancers. Basal cell and squamous cell cancers rarely result in death. Australia and New Zealand have the highest rates of melanoma in the world. The aim of the study is to study the prevalence, clinicopathological presentation and management of skin malignancies. MATERIALS AND METHODS This is a prospective study conducted for a period of 2 years and analysed 30 cases of malignant skin tumours proven on histopathology with respect to prevalence, age, sex distribution, common site of occurrence and treatment modalities adopted. RESULTS In the present study, 47% of squamous cell carcinoma occurred between 50-59 years of age, more common in males with site predilection of lower limbs. Basal cell carcinoma was more common in the age group, 60-69 years (55.6% and more common in females (66.7%. The commonest site of occurrence of basal cell carcinoma was in the lower eyelid. Malignant melanoma was more common in the age group 50-59 years (75% and more common in females (75%. The commonest site of occurrence of melanoma was lower extremity. All the cases were treated with surgery. CONCLUSION Non-melanoma skin malignancies like squamous cell carcinoma and basal cell carcinoma are more common than melanoma and have good prognosis. The mean age of occurrence of the tumours was around 60 years of age and responded well with surgical resection.

    Full Text Available Background. The incidence of skin cancer is increasing in the world as well as in our country. Decades of research have increased the understanding of the ethiopathogenetic influences and risk factors for development of malignant skin tumors and stimulated efforts to promote their prevention. There are successes of prevention programs in some places in the world expressing with the reduction of mortality because of the cutaneous malignant melanoma. A primary prevention of a skin cancer attempts to change population knowledge, attitudes and beliefs about sunlight, leading to reduce of sunlight exposure.Conclusions. In this article we are discussing guidelines for photoprevention. The best approach to it is a reduction in the overall exposure to sunlight. The natural protection with the use of shade, clothing and hats is promoted as the best protection. Sunscreens are assumed as an important component of adjuvant photoprotection based on their convenience of use and also on their widespread promotion. While it has been argued that all tanning is a manifestation of skin injury, avoiding of artificial tanning devices is proposed also.

  3. FLUORESCENT DIAGNOSTICS OF MALIGNANT SKIN TUMORS WITH CHLORIN SERIES PHOTOSENSITIZERS

    Full Text Available The article shows possibilities in fluorescence imaging of malignant skin tumors with chlorin series photosensitizers (PS photolon and fotoditazin. The regularities of photosensitizer accumulation from the data of local fluorescence spectroscopy depending on the PS and its dose, the clinical picture and the histological form of the malignant skin neoplasm is investigated. It is shown that the level and selectivity of PS accumulation in the tumor focus depends on the PS dose. In studies on 10 patients with basal cell skin cancer after the introduction of fotoditazin at a dose less than 1 mg/kg, fluorescent contrast between tumor and healthy tissue varied between 1.3 and 9.5, the average was 2.8±0.3; for patients who had the administered fotoditazin dose of 1 mg/kg, fluorescent contrast was 2.9±0.4, varying from 1.4 to 5. In a study with 127 patients after the introduction of photolon in the dose of 0.7-1 mg/kg, the average value of the fluorescence intensity in relative units in the intact skin was 6.9±0.3 (min 4.6, max 12.2, at a dose of 1.1 to 1.4 mg/kg – 8.0±0.3 (min 4.6, max 12.5, at a dose of 1.5-2 mg/kg – 9.9±0.7 (min 5.7, max 20.3. It is also shown that fluorescence intensity of malignant neoplasm of the skin with the same dose of the photosensitizer depends on the neoplasm’s clinical and histological forms. So, 3 hours after the introduction of photolon at a dose of 1.3 mg/kg the average fluorescent contrast in the surface type of skin cancer was 2.7±0.5, in the nodal form – 2.3±0.2, in erosive-ulcerative form – 3.6±0.3. In patients with nodular form of squamous skin cancer after the introduction of photolon at a dose of 1.3 mg/kg fluorescent contrast was significantly higher (p<0.05 (average of 2.8±0.2 than in the nodular form of basal cell carcinoma after the introduction of photolon at the same dose (average of 2.1±0.2.

    Endocrine diseases may result in changes in cutaneous function and morphology, which cause various skin manifestations, including nonspecific or pathognomonic signs. Some of these manifestations are already known dermatologic diseases with only increased frequency in this patient group. As a result the skin may the play role of a screen displaying endocrine disorders, either due to hormone excess or deficiency. Awareness of the skin manifestations may permit prompt and adequate approach to the patients, and therefore facilitate the early diagnosis of the endocrine disease and even be life saving. Some of these manifestations may be recognized clinically, but sometimes they need to be confirmed histopathologically. In this article, many endocrine diseases and their associated skin lesions will be reviewed briefly.

    Kidneys and skin are seldom considered associated, but their relationship is more closer than generally believed. In some immunological diseases (SLE...) and genetic syndromes (tuberous sclerosis, Fabrys disease...) the cutaneous manifestations are integral parts of the clinical picture. In advanced uremia, besides the well-known itching skin lesions, calciphylaxis may appear, a typical example of cutaneous involvement secondary to the metabolic complications (calcium-phosphate imbalance) of the renal disease. Nephrogenic systemic fibrosis appears only in patients with renal failure and it has a very severe prognosis due to the systemic organ involvement. Moreover, there is a heterogeneous group of metabolic diseases, with renal involvement, that may be accompanied by skin lesions, either related to the disease itself or to its complications (diabetes mellitus, porphyrias). In systemic amyloidosis, fibrils may deposit even in dermis leading to different skin lesions. In some heroin abusers, in the presence of suppurative lesions in the sites of needle insertion, renal amyloidosis should be suspected, secondary to the chronic inflammation. Atheroembolic disease is nowadays frequently observed, as a consequence of the increasing number of invasive intravascular manoeuvres. Skin manifestations like livedo reticularis or the blue toe syndrome are the most typical signs, but often renal dysfunction is also present. In all these conditions, the skin lesion may be a first sign, a warning, that should arouse the suspicion of a more complex pathology, even with renal involvement. Being aware of this relationship is fundamental to accelerate the diagnostic process.

    Xeroderma pigmentosum is an autosomal recessive disease, characterized by vulnerability of the skin to solar radiation. Increase in sunlight-induced cancer is a direct consequence of an increase in mutated cells of the skin of patients with xeroderma pigmentosum. There is no specific technique for facial resurfacing in patients with xeroderma pigmentosum. In this article, a patient with xeroderma pigmentosum with multiple malignant melanomas on her face and radical excision of total facial skin followed by facial resurfacing with monoblock full-thickness skin graft from the abdomen is presented.

    2016-11-01

    The incidence of epithelial skin neoplasms, such as squamous cell carcinoma and basal cell carcinoma is significantly increasing worldwide. Leisure time solar UV exposure is causative in the overwhelming majority of cases in the general population; however, occupational exposure is responsible for a certain percentage of cases. Employees with a relevant exposure to polycyclic aromatic hydrocarbons in soot, raw paraffin, coal tar, anthracene, pitch or similar substances, to sunlight in outdoor occupations as well as to arsenic and ionizing radiation have a significantly increased risk to develop occupational skin cancer compared to the general population. In the official occupational disease list in the appendix of the German by-law on occupational diseases, the following occupational diseases concerning skin cancer are listed: BK 5102 "skin cancer and carcinoma in situ caused by soot, raw paraffin, coal tar, anthracene, pitch or similar substances" (e.g. various solid paraffins, asphalt and mazut as well as mineral oils, grease, cylinder and drilling oils), BK 5103 "squamous cell carcinoma or multiple actinic keratosis caused by natural UV radiation", BK 1108 "diseases caused by arsenic and its compounds" and BK 2402 "diseases caused by ionizing radiation". For further occupational exposure to carcinogenic substances and potential occupationally acquired skin tumors, no official lists are currently available. These cancers might be considered under a special opt out paragraph in the German Social Law (§ 9 para 2 SGB VII). Tumors in scars after occupational skin trauma or occupational burns are compensated as consequences of work accidents. The current official list of occupational skin cancers and new developments for expert opinions are described in this article.

  13. Incidence of malignant skin tumors in 14,140 patients after grenz-ray treatment for benign skin disorders

    Lindeloef, B.E.; Eklund, G.

    1986-01-01

    During the years 1949 to 1975, 14,237 patients received therapeutic doses of grenz rays for the treatment of benign skin disorders such as chronic eczema, psoriasis, and warts. The records of 14,140 of these patients (99.3%) formed the basis for an epidemiologic study of the incidence of skin malignancies in this population. Information about the patients, diagnoses, doses, and sites of treatment was obtained from separate records. The follow-up time was 15 years on the average. We searched the Swedish Cancer Registry, Stockholm, for records reporting the incidence of malignant skin tumors in the study population (incidences of basal cell carcinoma are not registered). The expected number of malignancies was calculated on the basis of age- and sex-standardized incidence data from the Swedish Cancer Registry. In 58 patients, a malignant skin tumor was diagnosed more than five years after grenz-ray therapy had first been administered. Nineteen patients had malignant melanomas, and 39 patients had other malignant skin tumors. The expected number of melanomas was 17.8, and that of other malignant skin tumors was 26.9. None of the patients with melanomas, and only eight of the patients with other malignant skin tumors, had received grenz-ray therapy at the site of the tumor. Six of these eight patients had also been exposed to other known carcinogens. Four hundred eighty-one patients had received an accumulated high dose of grenz rays (greater than or equal to 10 000 rad [greater than or equal to 100 Gy]) on one and the same area. No malignancies were found on those areas. Although we cannot exclude grenz-ray therapy as a risk factor in the development of nonmelanoma skin malignancies, this risk, if any, is small, if recommendations for therapy are followed

    The characteristic oily skin in individuals with parkinsonism has long been observed by clinicians. The oiliness seems to be associated with periods when the disease is most active. This seborrhea has been observed particularly in post-encephalitic parkinsonism, as well as in idiopathic paralysis agitans. It also occurs in phenothiazine-induced parkinsonism.

    Skin cancer incidence is rising, placing a burden on healthcare systems worldwide. This problem may even be more extensive than expected, since registration of (pre)malignancies of the skin is poor. To provide insight into the numbers of (pre)malignancies in patients with actinic keratosis (AK) or basal cell carcinoma (BCC) in 2 university and 2 general hospitals. The types and numbers of previous tumours and of tumours during a two-year follow-up were collected from 574 patients. Mean time between the first diagnosed (pre)malignancy and time of inclusion was 6.6 years. Overall, 60% had multiple types of (pre)malignancies. In BCC patients, 61% had multiple BCCs, in patients with squamous cell carcinoma (SCC), 40% had multiple SCCs. The combination 'BCC and SCC' occurred in 10%, 'BCC and AK' in 47%, 'SCC and AK' in 14%. High numbers of patients with multiple (pre)malignancies were found in this patient population in university and general hospitals, which may well reflect the Dutch hospital population. We conclude that skin cancer patients are more extensively affected than was expected up till now. Consequently, the management of skin cancer may be in need of adaptation in near future and the question arises whether dermatologists have the capacity for providing care for all these patients.

    Malignant melanoma is one of the most rapidly increasing cancer in the world. Breast metastases from melanoma are uncommon but could reflect a widespread disease. We report a case of malignant widespread melanoma presenting with bilateral breast nodules in a 39 year-old pre-menopausal Caucasian woman with an history of cutaneous melanoma of the trunk. Breast clinical examination revealed the presence of a hard and mobile lump located on the left breast. Ultrasound detected two bilateral nodules corresponding to oval opacities with well-defined edges and without calcifications or architectural distortion on mammography. Fine needle aspiration cytology performed on both breast nodules confirmed that the breast lesions were metastases from primary cutaneous malignant melanoma. A total-body CT examination detected brain, lung and abdominal lymph nodes metastases. The breast represents an uncommon site of metastatic disease from extra-mammary tumors. Imaging features of breast metastases from melanoma usually do not allow a differential diagnosis with breast primary tumors. Breast metastases may be asymptomatic or palpable as dense and well-circumscribed nodules. Breast metastases indicate a widespread disease and should lead to avoid aggressive surgical procedures because of the poor prognosis of patients affected by metastatic melanoma. The detection of bilateral breast metastases from melanoma is highly suggestive of metastatic multi-organ disease and could be useful to address the therapeutic approach.

    Malignant disease involving the skin represents a significant work load to the general radiotherapist and can involve interesting diagnostic and therapeutic decisions. Primary skin cancer is also relatively common and there is a need to provide an efficient service in which the first treatment is successful in the majority of patients. The reward for careful attention to technique is very considerable both in terms of clinical cancer control and functional results. Squamous cell carcinoma, basal cell carcinoma, and intra-epidermal carcinoma constitute the majority of the lesions dealt with clinically, but metastatic disease, lymphomas, and malignant melanomas are also referred regularly for opinions and may require radiotherapy. The general principle of the techniques of assessment and radiotherapeutic management to be described are equally applicable to any malignant skin tumour once the decision has been made to accept it for radiotherapy. Dosage and fractionation may have to be adjusted to allow for the nature of the disease process and the intent of the treatment

    Optical coherence tomography (OCT) is an emergent imaging tool used for noninvasive diagnosis of skin diseases. The present meta-analysis was carried out to assess the accuracy of OCT for the diagnosis of skin cancer. We conducted a systematic literature search though EMBASE, Medline, PubMed, the Cochrane Library, and Web of Science database for relevant articles published up to June 6, 2017. The quality of the included studies was assessed using the QUADAS-2 tool and the Oxford Levels of Evidence Scale. Statistical analyses were conducted using the software Meta-Disc version 1.4 and STATA version 12.0. A total of 14 studies involving more than 813 patients with a total of 1958 lesions were included in our analyses. The pooled sensitivity and specificity of OCT for skin cancer diagnoses were 91.8% and 86.7%, respectively. Subgroup analysis showed that the pooled sensitivities of OCT for detecting basal cell carcinoma (BCC), squamous cell carcinoma (SCC), actinic keratosis, and malignant melanoma were 92.4%, 92.3%, 73.8%, and 81.0%, respectively. The pooled specificities were 86.9%, 99.5%, 91.5%, and 93.8%, respectively. OCT appears to be useful for the detection of BCC and SCC. It is a valuable diagnostic method when screening for early skin cancers.

  1. Is diverticular disease associated with colonic malignancy?

    Science.gov (United States)

    Ekbom, Anders

    2012-01-01

    Colon cancer and diverticular disease have common characteristics; there are increases in the incidences in both disease entities and these diseases are more common in the westernized world. There is also an increase in the age-specific incidence with advancing age. Similar dietary features have been implicated for both diseases and already during the 1960s it was postulated by Burkitt that there is an association. Observational studies initially were able to demonstrate that patients with a history of diverticular disease of the colon had an increased risk of colon cancer, especially in the left side. However, the results from these studies have not been consistent, and problems like selection bias and confounding by indication have been major drawbacks in order to interpret the results and infer causality. Recent studies, which have had a better assessment of diverticular disease by new diagnostic methods, do not support such an association to the same extent as previously. Moreover, surveillance bias has become an increasing problem as patients with diverticular disease of the colon are subjected to a higher diagnostic intensity than other individuals in a population-based setting. A critical evaluation of the studies published so far therefore clearly indicates that the proposed association between diverticular disease and colonic malignancy is not evidence based, which should have an impact on clinical practice as well as on how to deal with these patient groups within the realms of a screening program.

    2014-10-01

    Cutaneous malignancies have been significantly associated with autoimmune connective tissue diseases (ACTDs). This review focuses on the current state of knowledge on skin cancer risk in the most prevalent ACTDs in dermatology including lupus erythematosus, scleroderma, dermatomyositis and Sjögren syndrome. Potential pathogenetic mechanisms for the association between ACTDs and malignancy involve disease-related impairment of immune system, sustained cutaneous inflammation, drug-associated immune suppression and increased susceptibility to acquired viral infections. An additional causal role might be played by environmental factors such as UV exposure and smoking. The occurrence of skin cancer can have a profound impact on the already compromised quality of life of ACTD patients. Therefore, effective screening and monitoring strategies are essential for ACTD patients as early detection and prompt therapeutic intervention can reduce morbidity and mortality in these patients.

    Despite commanding essentially universal scientific consensus, climate change remains a divisive and poorly understood topic in the United States. Familiarity with this subject is not just for climate scientists. The impact of climate change on human morbidity and mortality may be considerable; thus, physicians also should be knowledgeable in this realm. Climate change science can seem opaque and inferential, creating fertile ground for political polemics and undoubtedly contributing to confusion among the general public. This puts physicians in a pivotal position to facilitate a practical understanding of climate change in the public sphere by discussing changes in disease patterns and their possible relationship to a changing climate. This article provides a background on climate change for dermatologists and highlights how climate change may impact the management of skin disease across the United States.

    2013-01-01

    Full Text Available Abstract Definition of the disease Malignant atrophic papulosis (MAP, described independently by Köhlmeier and Degos et al., is a rare, chronic, thrombo-obliterative vasculopathy characterized by papular skin lesions with central porcelain-white atrophy and surrounding teleangiectatic rim. Epidemiology Less than 200 cases have been described in the literature. The first manifestation of MAP usually occurs between the 20th and 50th year of life. Clinical description The cutaneous clinical picture is almost pathognomonic. The histology is not consistent but in most cases it shows a wedge-shaped connective tissue necrosis in the deep corium due to a thrombotic occlusion of the small arteries. In the systemic variant, manifestations mostly occur at the intestine and central nervous system. Etiology The etiopathogenesis of the disease remains unknown, a genetic predisposition may occur. Vasculitis, coagulopathy or primary dysfunction of the endothelial cells have been implicated. Diagnostic methods Diagnosis is only based on the characteristic skin lesions. Differrential diagnosis It depends on the clinical presentation of MAP, but systemic lupus erythematosus and other connective tissue diseases need to be considered. Management No effective treatment exists for the systemic manifestations, while compounds that facilitate blood perfusion have achieved a partial regression of the skin lesions in single cases. Prognosis An apparently idiopathic, monosymptomatic, cutaneous, benign variant and a progressive, visceral one with approx. 50% lethality within 2–3 years have been reported. Systemic manifestations can develop years after the occurrence of skin lesions leading to bowel perforation and peritonitis, thrombosis of the cerebral arteries or massive intracerebral hemorrhage, meningitis, encephalitis, radiculopathy, myelitis.

    2002-01-01

    The clinical application of radiofrequency tumor ablation in primary liver tumors and metastatic liver disease is rapidly growing because this technique has proven to be simple, safe, and effective in first clinical studies. Most of the patients with malignant liver disease are not candidates for surgical resection due localisation or comorbidity, so radiofrequency therapy offers a good alternative for inoperable patients. With this method, high frequency alternating current is delivered to tissue via a needle electrode, the produced heat leads to coagulation necrosis. The largest focus of necrosis that can be induced with the currently available systems is approximately 4-5 cm with a single application. The radiofrequency needle is usually placed with US or CT guidance. For follow up examinations CT and MRI can be used, they proved to be equally accurate in the assessment of treatment response.

    2010-08-01

    Full Text Available Abstracts Background Src family kinases (SFKs play an important role in cancer proliferation, survival, motility, invasiveness, metastasis, and angiogenesis. Among the SFKs, c-Src and c-Yes are particularly over-expressed or hyper-activated in many human epithelial cancers. However, only a few studies have attempted to define the expression and role of c-Src and c-Yes in cutaneous carcinomas. Objectives To investigate the expression of c-Src and c-Yes in cutaneous carcinomas to include malignant melanoma (MM, squamous cell carcinoma (SCC and basal cell carcinoma (BCC. Methods We examined 6 normal skin tissues and 18 malignant skin tumor tissues using western blotting for the expression of c-Src and c-Yes. In another set, 16 specimens of MM, 16 SCCs and 16 BCCs were analyzed for the expression of c-Src and c-Yes using immunohistochemical staining. Results Western blotting showed that c-Src was expressed in all malignant skin tumors, but not in normal skin, while c-Yes was expressed in MM and SCC, but not in BCC and normal skin. Immunohistochemical staining results of c-Src and c-Yes in MM, SCC, and BCC mirrored those of the western blot analysis. Conclusions c-Src, rather than c-Yes, plays a key role in the proliferation and progression of malignant skin cancers.

    Human skin and its immune cells provide essential protection of the human body from injury and infection. Recent studies reinforce the importance of keratinocytes as sensors of danger through alert systems such as the inflammasome. In addition, newly identified CD103(+) dendritic cells are strategically positioned for cross-presentation of skin-tropic pathogens and accumulating data highlight a key role of tissue-resident rather than circulating T cells in skin homeostasis and pathology. This Review focuses on recent progress in dissecting the functional role of skin immune cells in skin disease.

    Full Text Available Melanocytic tumors and melanomas in domestic animals include neoplasms composed of melanin-producing cells. In cattle, these tumors are rare and mostly benign, while malignant tumors are almost non-existent. The article reports the case of a female crossbred cow 38 months of age with a fluctuating mass located between the mandibular border and the left parotid region, about three months duration, with evident growth in the last thirty days. After surgical excision, a sample preserved in buffered formalin (10% was sent to the Laboratory of Pathology (University of Nariño—consisting of a fragment of 7.0 × 10.5 × 8.0 cm, ellipsoid, with skin and hair on one side, irregular surface, blackish brown, semi-soft consistency, and presence of shear translucent slimy content—for processing and inclusion in paraffin, cut to 5 μm thickness and stained with hematoxylin-eosin coloration. The forwarded tissue was classified as a neoplasm of malignant behavior derived from melanocytes, due to its cellular characteristics: growth pattern, pattern of distribution, severe cellular pleomorphism, anisocytosis, megalocytosis, nuclear pleomorphism, anisokaryosis, megalokaryosis, and involvement of blood vessel walls; additionally, the paraffin block was cut for immunohistochemical processing using monoclonal markers (S-100 DAKO® and Melan A DAKO®, contrasted with Mayer’s hematoxylin. Strong immunostaining of neoplastic cells is evident, and it constitutes the first reported case of this disease in Nariño (Colombia.

    Full Text Available The results of the experimental study of immune response of human skin malignant melanoma cells Mel 226 on photodynamic exposure are represented in the article. Photoinduced apoptosis of skin malignant melanoma was studied in vitro. The study showed that irradiation with the agent fotoditazin at dose of 0.5–2.5 µg/ml (6 and 10 min exposure 30 min before irradiation; irradiation parameters: wavelength of 662 nm, total light dose from 40 to 60 J/cm2 induced early apoptosis. The increase of the time of laser irradiation significantly accelerates the conversion of photosensitized tumor cells from early to late apoptosis.

    Full Text Available Streptococcus bovis is a Gram-positive bacterium causing serious human infections, including endocarditis and bacteremia, and is usually associated with underlying disease. The aims of the current study were to compare prevalence of the bacterium associated with malignant and nonmalignant gastrointestinal diseases and to determine the susceptibility of the isolated strains to different antimicrobial agents. The result showed that the prevalence of S. bovis in stool specimens from patients with malignant or with nonmalignant gastrointestinal diseases was statistically significant. This result may support the idea that there is correlation between S. bovis and the malignant gastrointestinal diseases.

  20. Indian Hedgehog Controls Proliferation and Differentiation in Skin Tumorigenesis and Protects against Malignant Progression

    Parisa Kakanj

    2013-07-01

    Full Text Available Mutations in the hedgehog pathway drive the formation of tumors in many different organs, including the development of basal cell carcinoma in the skin. However, little is known about the role of epidermal Indian hedgehog (Ihh in skin physiology. Using mouse genetics, we identified overlapping and distinct functions of Ihh in different models of epidermal tumorigenesis. Epidermal deletion of Ihh resulted in increased formation of benign squamous papilloma. Strikingly, Ihh-deficient mice showed an increase in malignant squamous cell carcinoma and developed lung and lymph node metastases. In a sebaceous gland tumor model, Ihh deficiency inhibited tumor cell differentiation. More mechanistically, IHH stimulated cell proliferation by activating the transcription factor GLI2 in human keratinocytes and human tumors. Thus, our results uncover important functions for Ihh signaling in controlling proliferation, differentiation, malignant progression, and metastasis of epithelial cancer, establishing Ihh as a gatekeeper for controlling the grade of tumor malignancy.

    Chu, Chung-Ching; Di Meglio, Paola; Nestle, Frank O

    2011-02-01

    The skin immune system harbors a complex network of dendritic cells (DCs). Recent studies highlight a diverse functional specialization of skin DC subsets. In addition to generating cellular and humoral immunity against pathogens, skin DCs are involved in tolerogenic mechanisms to ensure the maintenance of immune homeostasis, as well as in pathogenesis of chronic inflammation in the skin when excessive immune responses are initiated and unrestrained. Harnessing DCs by directly targeting DC-derived molecules or selectively modulate DC subsets is a convincing strategy to tackle inflammatory skin diseases. In this review we discuss recent advances underlining the functional specialization of skin DCs and discuss the potential implication for future DC-based therapeutic strategies.

    Raap, U; Kapp, A

    2010-04-01

    Understanding the complex mechanism of allergic inflammatory skin diseases has been a main challenge of clinical and experimental research for years. It is well known that the inflammatory response is also controlled by tissue resident cells including neurons and structural cells. Thus, allergic inflammation triggers neuronal dysfunction and structural changes in diseased skin. Prime candidates for the interaction between immune, structural, and neuronal cells are presented by neurotrophins. Neurotrophins have initially been described for their neurotrophic capacity. However, recent evidence emerges that neurotrophins display bidirectional interaction pathways in activating structural cells, immune cells in addition to neurons. Neurotrophins including brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) are upregulated in allergic inflammatory skin diseases. Further, structural cells, neurons and tissue resident cells have not only been shown to be a target but also a source of neurotrophin. In this regard, eosinophil granulocytes which are key target effector cells in chronic inflammatory skin have been identified as a target of neurotrophins but are also capable of neurotrophin production. Thus, neuroimmune interaction mechanisms in allergic inflammatory skin display a novel pathophysiological aspect in which neurotrophins serve as prime candidates for bidirectional interaction mechanisms. In this review, we provide an actual overview of neurotrophins in healthy and diseased skin with special emphasis on atopic dermatitis and therapeutic implications.

    1992-07-06

    About 700 new cases of malignant melanoma of the skin are registered annually in Denmark. The incidence is increasing rapidly and the number of new cases increases by more than 5% per annum. The most important phenotypical risk factors are the number of acquired pigmented naevi and exposure to sunlight is the most important risk factor in the external environment so that severe sunburn in children and intermittent intense exposure to sunlight increase the risk of melanoma. The thickness of the tumour at the time of the diagnosis is the most important prognostic factor. The prognosis deteriorates with increasing thickness. Treatment is primarily surgical. In cases of inoperable local melanoma and regional recurrences, irradiation may be administered. Chemotherapy and/or immunotherapy are of experimental character. In the light of the rapidly increasing incidence, it is important that knowledge of risk factors for development of the disease and the clinical characteristics of early melanoma is spread to not only the medical profession but also to the general public.

    1997-01-01

    To evaluate whether or not previously known CT criteria for differentiating malignant and benign pleural diseases are useful in the differentiation of diffuse malignant pleural diseases and tuberculosis. We retrospectively analyzed CT scans of 42 patients comprising 20 cases of malignant pleural diseases and 22 cases of tuberculous pleural diseases, according to previously known CT criteria for differentiating malignant and benign pleural diseases. The most common shape of pleural effusion was crescentic in malignant pleural diseases and loculated in tuberculosis. The aggressive nature of pleural effusion, pleural rind, and pleura thickening was 1.5 times more frequently observed in malignant pleural diseases than in tuberculosis. Smooth thickening or smooth nodular pleural thickening and extrapleural deposition of fat were 1.5 times more frequently found in tuberculous than in malignant pleural diseases. Interruption of pleural thickening was found twice as frequently in malignant pleural diseases as in tuberculosis. Decreased lung volume was found twice as frequently in tuberculous as in malignant pleural diseases. Anatomical mediastinal pleural involvement was three times, and irregular nodular pleural thickening nine times more frequent in malignant pleural diseases than in tuberculosis. The sensitivity and specificity of CT findings above 70%, and thus suggesting malignant pleural diseases, were as follows : 1) aggressive nature of pleural fluid collection extending to the azygoesophageal recess or tongue of the lung (51.5%, 75%); 2) involvement of anatomical mediastinal pleura (69.2%, 73.7%); 3) irregular nodular pleural thickening (87.5%, 69%). Although there in overlap between previously known CT criteria for the differentiation of benign and malignant pleural diseases, the aggressive nature of pleural fluid collection extending to the azygoesophageal recess or tongue of the lung, the involvement of anatomical mediastinal pleura and irregular nodular

    A new study published in the journal Nature Biomedical Engineering 1 documents a novel diagnostic technology that exploits topically applied nanotechnology to detect skin tissue biomarkers for diagnosis. This concept is demonstrated by noninvasively imaging connective tissue growth factor (CTGF) mRNA in abnormal scar cells, whole tissue, and animal models. In this commentary, we highlight the main findings and discuss their implications. Successful implementation in the clinic could give rise to self-applied, biopsy-free diagnostic technology and significantly reduce healthcare burden. Crucially, noninvasive visualization of disease biomarkers, mobile device signal acquisition, and Internet-enabled transmission could significantly transform the diagnosis of skin disease and other superficial tissues.

    McGregor, J.F.

    1979-01-01

    Epithelial lesions induced by irradiation of rat skin were studied to determine (a) the relationship of malignancy to dose, (b) the types of lesions and circumstances leading to overt malignancy, and (c) the growth rates of lesions progressing to malignancy versus those of lesions remaining benign. High doses of radiation were shown to be associated with the production of epidermal cancers, the maximum yield being obtained at 6,400 rads. Conversely, a peak yield of noncancerous lesions was obtained at 1,600 rads. This association between malignancy and high dose was consistent for cancers evolving from warts, cysts, and chronic ulcers. Although the proportion of warts among the induced lesions was much higher than that of the cysts or chronic ulcers (76, 14, and 10%, respectively), the likelihood of warts becoming cancerous was substantially lower (14, 23, and 21%). The combined data for all doses showed that the latency period of the epidermal cancers was significantly (P = 0.015) shorter than that of the benign tumors. Rapid growth rates were observed for warts, cysts, and chronic ulcers progressing to overt cancer, and these did not overlap at any point on the growth scale with rates for benign tumors. This finding suggested that the potential for malignant development had been established early in the carcinogenic process, very likely at induction

    With the advent of smartphone devices, an increasing number of mHealth applications that target melanoma identification have been developed, but none addresses the general context of melanoma and nonmelanoma skin cancer identification. In this study a smartphone application using fractal and classical image analysis for the risk assessment of skin lesions is systematically evaluated to determine its sensitivity and specificity in the diagnosis of melanoma and nonmelanoma skin cancer along with actinic keratosis and Bowen's disease. In the Department of Dermatology, Catharina Hospital Eindhoven, The Netherlands, 341 melanocytic and nonmelanocytic lesions were imaged using SkinVision app; 239 underwent histopathological examination, while the rest of 102 lesions were clinically diagnosed as clearly benign and not removed. The algorithm has been calibrated using the images of the first 233 lesions. The calibrated version of the algorithm was used in a subset of 108 lesions, and the obtained results were compared with the medical findings. On the 108 cases used for evaluation the algorithm scored 80% sensitivity and 78% specificity in detecting (pre)malignant conditions. Although less accurate than the dermatologist's clinical eye, the app may offer support to other professionals who are less familiar with differentiating between benign and malignant lesions. An mHealth application for the risk assessment of skin lesions was evaluated. It adds value to diagnosis tools of its type by taking into consideration pigmented and nonpigmented lesions all together and detecting signs of malignancy with high sensitivity.

    Most malignancies show a steep increase of incidence with growing age. Because of this age specific incidence and the general aging of the population in western industrial countries the number of elderly cancer patients continuously and rapidly increases. Despite this development elderly cancer patients are currently underrepresented in clinical trials. This is caused in part by the lack of a common definition of the elderly patient and by the fact that a part of the elderly patients suffers from co-morbidities, not allowing a more dose intense treatment in these patients. It is one of the key current challenges to compensate this deficit and to develop therapeutic concepts specifically for the elderly patients, taking the individual somatic, but also social situation and finally the quality and perspective of life of the elderly patient into account.

The specificity of the immune response and potential for establishing long-term tumor immunity compels researchers to continue investigations into immunotherapeutic approaches for cancer. A number of immunotherapeutic strategies have arisen for the treatment of malignant disease, including various vaccination schemes, cytokine therapy, adoptive cellular therapy, and monoclonal antibody therapy. This paper describes each of these strategies and discusses some of the associated successes and limitations. Emphasis is placed on the integration of techniques to promote optimal scenarios for eliminating cancer.

    An early diagnosis of malignancies correlates directly with a better prognosis. Yet for many malignancies there are no readily available, noninvasive, cost-effective diagnostic tests with patients often presenting too late for effective treatment. This article describes for the first time the use of fiber diffraction patterns of skin or fingernails, using X-ray sources, as a biometric diagnostic method for detecting neoplastic disorders including but not limited to melanoma, breast, colon and prostate cancers. With suitable further development, an early low-cost, totally noninvasive yet reliable diagnostic test could be conducted on a regular basis in local radiology facilities, as a confirmatory test for other diagnostic procedures or as a mass screening test using suitable small angle X-ray beam-lines at synchrotrons.

  3. Complement Activation in Inflammatory Skin Diseases

    2018-04-01

    Full Text Available The complement system is a fundamental part of the innate immune system, playing a crucial role in host defense against various pathogens, such as bacteria, viruses, and fungi. Activation of complement results in production of several molecules mediating chemotaxis, opsonization, and mast cell degranulation, which can contribute to the elimination of pathogenic organisms and inflammation. Furthermore, the complement system also has regulating properties in inflammatory and immune responses. Complement activity in diseases is rather complex and may involve both aberrant expression of complement and genetic deficiencies of complement components or regulators. The skin represents an active immune organ with complex interactions between cellular components and various mediators. Complement involvement has been associated with several skin diseases, such as psoriasis, lupus erythematosus, cutaneous vasculitis, urticaria, and bullous dermatoses. Several triggers including auto-antibodies and micro-organisms can activate complement, while on the other hand complement deficiencies can contribute to impaired immune complex clearance, leading to disease. This review provides an overview of the role of complement in inflammatory skin diseases and discusses complement factors as potential new targets for therapeutic intervention.

    The objective of this study was to be able to distinguish between healthy skin tissue and malignant ones, furthermore determining a unique pattern of roughness for each skin lesion by microtopographic analysis of the skin surface of Mexican patients during the period from April to October 2002. The standard technique used in this study for the diagnosis of skin cancer and the comparison of the results was the haematoxylin-eosin histopathological technique. Latex impressions were taken from skin lesions as well as from the healthy skin of each patient to serve as control samples. These impressions were analysed by the MICROTOP.03.MFC microtopographic system inspection. It was observed that when the tumour becomes rougher, more malign will be the lesion. On average, the melanoma present an increase of roughness of 67% compared to healthy skin, obtaining a roughness relation of 1:2.54. The percentage decreases to 49% (49%, 1:60) in the case of basal cell carcinoma and to 40% in pre-malignant lesions such as melanocytic nevus (40%, 1:150). In benign lesions such as the seborrhoea keratosis only a small increase in roughness was noted (4%, 1:0.72). Microtopographic inspection of the skin surface can be considered as a complementary diagnostic technique for skin cancer

    Full Text Available We report a case of a 38-year-old man presenting with bilateral lower extremity weakness and paresthesias that progressed during a 4-month period to severe polyneuropathy forcing the patient to be bed bound. Throughout his multiple hospitalizations, he was treated erroneously for chronic inflammatory demyelinating polyneuropathy, without significant improvement in his symptoms. In addition, he developed hepatosplenomegaly (organomegaly; endocrinopathies such as diabetes mellitus, central hypogonadism, and hypothyroidism; monoclonal spike evidenced in the serum electrophoresis; and hyperpigmentation of skin, altogether consistent with POEMS syndrome. During his last hospitalization he developed excruciating pain on his left hip, and imaging revealed the presence of a 9 × 6 cm osteolytic mass with sclerotic rim in the left acetabulum. Biopsy of the mass confirmed an isolated IgG lambda plasmacytoma. The patient received radiation to his left acetabular lesion followed by left hip replacement. Subsequently, the patient underwent autologous bone marrow transplant. Eighteen months after his initial presentation, he had satisfactory clinical response and is functional without significant limitations. POEMS syndrome is a rare paraneoplastic syndrome secondary to an underlying plasma cell disorder, which can oftentimes be overlooked and misdiagnosed. The median age of presentation is 51 years, and only 31% of the cases occur in fairly young patients under the age of 45 as evidenced in this case. As clinicians, we should be aware of the constellation of features associated with POEMS syndrome and be able to recognize them promptly.

    Radioiodine treatment for thyroid disease has been given for half a decade in Sweden. The most common indication for treatment is hyperthyroidism, when iodine uptake is high. The situation in which radioiodine treatment is used in thyroid cancer is less favourable and measures therefore have to be taken to optimize the treatment. Treatment should be performed early in the course of the disease to achieve the highest possible differentiation. Before treatment the iodine and goitrogen intake should be kept low. Stimulation of the thyrocytes by thyroid-stimulating hormone (TSH) should be high. It is conventionally achieved by thyroid hormone withdrawal rendering the patient hypothyroid, or by the recently available recombinant human TSH (rhTSH) which can be recommended for ablation of the thyroid remnant after thyroidectomy and for treatment of metastases in fragile patients unable to undergo hypothyroidism. Finally, stunning - the negative effect of a prior test dose from radioactive iodine - should be avoided.

    Recently named one of the most influential phone applications, Instagram continues to grow in popularity [1]. Instagram consists of images and video posts, making it ideal for education and communication within the visual field of dermatology. In this study, we seek to determine the presence of dermatology-related content with regard to the most common cutaneous diseases of the world. We searched the account types and hashtags associated with the eight most common skin diseases globally as identified by the Global Burden of Disease (GBD) study by Hollenstein et al.: eczema, psoriasis, acne,pruritus, alopecia, decubitus ulcer, urticaria, andscabies [9]. The majority of Instagram accounts included patient experiences (n=73), private accounts(n=52), and disease advocacy and awareness groups(n=20), (total n=221). We further investigated over 2 million skin disease hashtags. The greatest numbersof hashtags were the following: #acne (n = 1,622,626),#alopecia (n = 317,566), and #eczema (n = 196,115). Our results demonstrate that patients interact withone another through Instagram. As social networking platforms become more frequently used as a source of information for patients and patient support, medical professionals must gain awareness of content available through Instagram and consider it as a means to educate the public.

    Discrimination of benign and malignant melanocytic lesions is a major issue in clinical dermatology. Assessment of the thickness of melanoma is critical for prognosis and treatment selection. We aimed to evaluate a novel optical computed tomography (optical-CT) system as a tool for three-dimensional (3-D) imaging of melanocytic lesions and its ability to discriminate benign from malignant melanocytic lesions while simultaneously determining the thickness of invasive melanoma. Seventeen melanocytic lesions, one hemangioma, and normal skin were assessed immediately after their excision by optical-CT and subsequently underwent histopathological examination. Tomographic reconstructions were performed with a back-propagation algorithm calculating a 3-D map of the total attenuation coefficient (AC). There was a statistically significant difference between melanomas, dysplastic nevi, and non-dysplastic nevi, as indicated by Kruskal-Wallis test. Median AC values were higher for melanomas compared with dysplastic and non-dysplastic nevi. No statistically significant difference was observed when thickness values obtained by optical-CT were compared with histological thickness using a Wilcoxon sighed rank test. Our results suggest that optical-CT can be important for the immediate prehistological evaluation of biopsies, assisting the physician for a rapid assessment of malignancy and of the thickness of a melanocytic lesion.

    To describe the characteristics of patients with occupational skin disease (OSD) in a tertiary referral clinic in Victoria, Australia. A retrospective review was conducted of records from patients seen at the Occupational Dermatology Clinic in Melbourne, Australia between 1 January 1993 and 31 December 2010. Of the 2894 people assessed in the clinic during the 18-year period, 44% were women and 56% were men. In all, 2177 (75%) were diagnosed with occupational skin disease (OSD). Of the patients with a work-related skin condition, 45% (n = 979) were considered to be atopic. The most common diagnosis in those with OSD was irritant contact dermatitis (ICD) (44%), followed by allergic contact dermatitis (33%) and endogenous eczema (11%). Women were significantly more likely to have soaps and detergents (P Occupational groups with the highest incidence of OSD were the hair and beauty professions (70 per 100 000), followed by machine and plant operators (38 per 100 000) and health-care workers (21 per 100 000). We confirm the importance of occupational contact dermatitis as the most common cause of OSD, with ICD being the most common diagnosis. There are differences in the causes of ICD between our group of male and female workers. For the first time in Australia, rates of OSD in certain industries have been calculated. © 2015 The Australasian College of Dermatologists.

  14. Half body irradiation of malignant diseases in childhood

    2000-01-01

    The possibilities of modern medicine make the prognosis of children with malignant diseases more optimistic, compared to adult patients. At the present stage the favourable outcome of pediatric oncological diseases varies within the limits of 50 - 80 %. Despite the good treatment results after optimal complex treatment, the rest of the ill children represent a serious therapeutical problem. The achieved good local tumor control after performed radiotherapy represents a potential for its application as a systemic therapy in patients with advanced or resistant to chemotherapy tumours. The radiobiological bases of the half body irradiation as a systemic therapy in pediatric oncology and as one of the main forms of large field irradiation are considered. The important clinical investigations have been discussed. Half body irradiation can be considered as a valuable alternative of chemotherapy and as a complementary systemic treatment in the case of advanced malignant diseases in children's age. (author)

    It is well known that Helicobacter pylori infection is associated with many nonmalignant disorders such as gastritis, peptic ulcer, gastroesophageal reflux disease (GERD), gastric polyp, nonsteroidal anti-inflammatory drug (NSAID)/aspirin-induced gastric injury, and functional dyspepsia. In 2008, interesting articles on the association of H. pylori infection with these disorders were presented, some of which intended to reveal the mechanisms of inter-individual differences in response to H. pylori infection, and have demonstrated that genetic differences in host and bacterial factors as well as environmental factors account for these differences. A decline in the occurrence of peptic ulcer related to H. pylori was confirmed. An inverse relationship between H. pylori infection and GERD was also confirmed but the impact of gastric atrophy on the prevention of GERD remained debatable. For NSAID-induced gastric injury, eradication of H. pylori infection has been recommended. During this year, eradication of H. pylori infection was recommended for patients treated with antiplatelet therapy as well as aspirin and NSAID. It was also reported that for patients with functional dyspepsia, eradication of H. pylori offers a modest but significant benefit.

    The prevalence of Helicobacter pylori-associated peptic ulcers, in particular duodenal ulcers, is decreasing following decreasing prevalence of H. pylori infection, while the frequency of non-steroidal anti-inflammatory drugs (NSAIDs)-induced and H. pylori-negative idiopathic ulcers is increasing. The incidence of bleeding ulcers has been stable during the last decades. Several putative H. pylori virulence genes, i.e., cag, vacA, babA, or dupA, as well as host-related genetic factors like IL-1beta and TNFalpha-gene polymorphism, have been proposed as risk factors for duodenal ulcer. H. pylori eradication may prevent NSAID complications, in particular, when it is performed before introduction of NSAIDs. There is a complex association between H. pylori and gastroesophageal reflux disease (GERD), and the impact of H. pylori eradication on the appearance of GERD symptoms depends on various host- and bacteria-related factors. Eradication of H. pylori in GERD is recommended in patients before instauration of a long-term PPI treatment to prevent the development of gastric atrophy. A small proportion (10%) of non-ulcer dyspepsia cases may be attributed to H. pylori and may benefit from eradication treatment. A test-and-treat strategy is more cost-effective than prompt endoscopy in the initial management of dyspepsia.

They were active workers in the repair industry who had been employed for at least six months. Business owners, sellers of spare parts and accounting officers were not included. The employees were examined at their workplaces and the working conditions were observed. Detailed dermatological examination was performed. The mean age of the 405 workers who participated in the study was 27.7 ± 10.3. The mean working time of employees was 13.3 ± 10.4 years. All of the employees were male. Dermatological diseases were not detected in 144 out of 405 workers (35.6%) and at least one condition was diagnosed in 261 (64.4%). The most frequent diagnosis was callus, hyperkeratosis, clavus (27.7%), followed by nail changes (16.8%) and superficial mycoses (12.1%). Contact dermatitis was seen at a rate of 5.9%. Traumatic lesions such as hyperkeratotic lesions and nail changes were found most frequently. Traumatic lesions were common among individuals who did not use gloves. Most nail changes were localized leuconychia, a finding not reported in the studies on automotive industry workers. In accordance with the literature, irritant contact dermatitis was observed in patients with a history of atopy and who had been working for a long time. Occupational skin diseases comprise an important field in dermatology, deserving much attention. Further studies on occupational dermatology are necessary.

  18. Advances in the in Vivo Raman Spectroscopy of Malignant Skin Tumors Using Portable Instrumentation

    Full Text Available Raman spectroscopy has emerged as a promising tool for real-time clinical diagnosis of malignant skin tumors offering a number of potential advantages: it is non-intrusive, it requires no sample preparation, and it features high chemical specificity with minimal water interference. However, in vivo tissue evaluation and accurate histopathological classification remain a challenging task for the successful transition from laboratory prototypes to clinical devices. In the literature, there are numerous reports on the applications of Raman spectroscopy to biomedical research and cancer diagnostics. Nevertheless, cases where real-time, portable instrumentations have been employed for the in vivo evaluation of skin lesions are scarce, despite their advantages in use as medical devices in the clinical setting. This paper reviews the advances in real-time Raman spectroscopy for the in vivo characterization of common skin lesions. The translational momentum of Raman spectroscopy towards the clinical practice is revealed by (i assembling the technical specifications of portable systems and (ii analyzing the spectral characteristics of in vivo measurements.

    This contribution evolved from my work in a European network and is dedicated to the rare genetic skin diseases. To gain a deeper knowledge about the question, what it means to suffer from a genetic skin disease, I have discussed the concepts of skin in philosophical and theological anthropology. Presuming that ancient interpretations of skin diseases (moral and cultical impurity) are still relevant today, feminist Christian theology shows the ways of deconstructing stigmatizing paradigma by using the body as a hermeneutic category. Skin becomes the "open borderline" of the human being, pointing out both the social vulnerability and the transcendent capacity of the human person.

    T, B cells in the peripheural blood of patients with malignant diseases were investigated. The percentages of T cells in patients with malignant lymphomas correlated to the extent of disease determined by clinical stagings of Ann Arbor's classification, in stages III and IV T-cells decreased to compare with those in stages I and II, while B-cells did not show any changes. Absolute numbers of lymphocytes, blastogenesis induced by PHA or PWM decreased remarkably during combination chemotherapies and during radiotherapy whereas the percentages of T-cells measuring in the same patients did not influenced consistently by these treatments. The DNA pattern of lymphocytes during treatments was examined by Flow-Microphotometry and the result suggested that those lymphocytes were damaged by treatments and subsequently they were refractory to the action of mitogens. The results indicate that selective timing needs between chemotherapy and immunotherapy. (auth.)

    Melanoma accounts for 5% of all skin cancers. The risk of metastasis is related to the thickness of the tumour, and can affect local, regional and distant sites. Adrenal metastasis from melanoma of the head and neck is uncommon and often asymptomatic. Addison's disease as a presentation of metastatic melanoma is extremely rare and we are unaware of previous reports in the world literature. We report a case of a patient with metastatic melanoma presenting with signs and symptoms of Addison's disease.

  3. Bacterial Infections Following Splenectomy for Malignant and Nonmalignant Hematologic Diseases

    Splenectomy, while often necessary in otherwise healthy patients after major trauma, finds its primary indication for patients with underlying malignant or nonmalignant hematologic diseases. Indications of splenectomy for hematologic diseases have been reducing in the last few years, due to improved diagnostic and therapeutic tools. In high-income countries, there is a clear decrease over calendar time in the incidence of all indication splenectomy except nonmalignant hematologic diseases. However, splenectomy, even if with different modalities including laparoscopic splenectomy and partial splenectomy, continue to be a current surgical practice both in nonmalignant hematologic diseases, such as Immune Thrombocytopenic Purpura (ITP), Autoimmune Hemolytic Anemia (AIHA), Congenital Hemolytic Anemia such as Spherocytosis, Sickle Cell Anemia and Thalassemia and Malignant Hematological Disease, such as lymphoma. Today millions of people in the world are splenectomized. Splenectomy, independently of its cause, induces an early and late increase in the incidence of venous thromboembolism and infections. Infections remain the most dangerous complication of splenectomy. After splenectomy, the levels of antibody are preserved but there is a loss of memory B cells against pneumococcus and tetanus, and the loss of marginal zone monocytes deputed to immunological defense from capsulated bacteria. Commonly, the infections strictly correlated to the absence of the spleen or a decreased or absent splenic function are due to encapsulated bacteria that are the most virulent pathogens in this set of patients. Vaccination with polysaccharide and conjugate vaccines again Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria meningitidis should be performed before the splenectomy. This practice reduces but does not eliminate the occurrence of overwhelming infections due to capsulated bacteria. At present, most of infections found in splenectomized patients are due to Gram

    Skin manifestations associated with chronic kidney disease are very common. Most of these conditions present in the end stages and may affect the patient's quality of life. Knowledge of these entities can contribute to establishing an accurate diagnosis and prognosis. Severe renal pruritus is associated with increased mortality and a poor prognosis. Nail exploration can provide clues about albumin and urea levels. Nephrogenic systemic fibrosis is a preventable disease associated with gadolinium contrast. Comorbidities, such as diabetes mellitus and secondary hyperparathyroidism, can lead to acquired perforating dermatosis and calciphylaxis, respectively. Effective and innovative treatments are available for all of these conditions. Copyright © 2015 Elsevier España, S.L.U. and AEDV. All rights reserved.

    In recent years, both tissue engineering and microfluidics have significantly contributed in engineering of in vitro skin substitutes to test the penetration of chemicals or to replace damaged skins. Organ-on-chip platforms have been recently inspired by the integration of microfluidics and biomaterials in order to develop physiologically relevant disease models. However, the application of organ-on-chip on the development of skin disease models is still limited and needs to be further developed. The impact of tissue engineering, biomaterials and microfluidic platforms on the development of skin grafts and biomimetic in vitro skin models is reviewed. The integration of tissue engineering and microfluidics for the development of biomimetic skin-on-chip platforms is further discussed, not only to improve the performance of present skin models, but also for the development of novel skin disease platforms for drug screening processes. © 2016 WILEY-VCH Verlag GmbH & Co.

    Chronic skin disease has a devastating effect on a person's physical and psychological well-being. Skin disease significantly impacts all aspects of a patient's life including school, relationships, career choices, social and leisure activities, and sexual life. The physical, psychological, and social consequences affect not only the patients, but also caregivers and family members as well. Common psychological problems associated with skin disease include, but are not limited to, feelings of stress, anxiety, anger, depression, shame, social isolation, low self-esteem, and embarrassment. Besides psychopharmacology, multiple psychotherapeutic techniques have proved to be helpful in addressing the psychological sequelae of skin disease. © Copyright 2018 Physicians Postgraduate Press, Inc.

    A 56-year old man attended the Dermatology Outpatients Department with the complaint of a localized, extremely itchy, erythematous papular lesion of acute onset on the ventral aspect of the right thigh. The patient was referred to the Microbiology Lab for the microscopic detection of the fungal elements. The KOH mount from the skin scrapings showed no fungal elements, but it showed the mites of Sarcopetes scabiei mange. The Sarcoptic Mange is noteworthy because of the fact that it is a zoonotic disease which can easily be passed on to humans. A close contact with infested pet dogs was considered as the main predisposing factor in this case. The response to the antiscabietic treatment was dramatic.

    Forty-four patients with malignant disease of the stomach (41 carcinomas, three non-Hodgkin lymphomas) and two patients with chronic gastric ulcers were examined by computer tomography before undergoing surgery. The ulcers, the non-Hodgkin lymphoma and the carcinomas stages pT2 to pT4 were easily demonstrated, as well as 66% of carcinomas in stage pT1. In addition to the primary tumour, it was possible to recognise lymph node and organ metastases. Two of the 46 patients were not submitted for surgery because of extensive metastases. (orig.) [de

    A single square centimetre of the human skin can contain up to one billion microorganisms. These diverse communities of bacteria, fungi, mites and viruses can provide protection against disease, but can also exacerbate skin lesions, promote disease and delay wound healing. This review addresses the current knowledge surrounding the healthy skin microbiome and examines how different alterations to the skin microbial communities can contribute to disease. Current methodologies are considered, changes in microbial diversity and colonisation by specific microorganisms are discussed in the context of atopic dermatitis, psoriasis, acne vulgaris and chronic wounds. The recent impact of modern Westernised lifestyles on the human skin microbiome is also examined, as well as the potential benefits and pitfalls of novel therapeutic strategies. Further analysis of the human skin microbiome, and its interactions with the host immune system and other commensal microorganisms, will undoubtedly elucidate molecular mechanisms for disease and reveal gateways for novel therapeutic treatment strategies. © 2015 The Australasian College of Dermatologists.

    Chronic pruritus is a major and distressing symptom of many cutaneous and systemic diseases and can significantly impair the patient's quality of life. Pruritus perception is the final result of a complex network involving dedicated nerve pathways and brain areas, and an increasing number of peripheral and central mediators are thought to be involved. Itch is associated with most cutaneous disorders and, in these circumstances, its management overlaps with that of the skin disease. Itch can also occur without associated skin diseases or primary skin lesions, but only with nonspecific lesions secondary to rubbing or scratching. Chronic itch with no or minimal skin changes can be secondary to important diseases, such as neurologic disorders, chronic renal failure, cholestasis, systemic infections, malignancies, and endocrine disorders, and may also result from exposure to some drugs. The search for the cause of pruritus usually requires a meticulous step-by-step assessment involving careful history taking as well as clinical examination and laboratory investigations. Few evidence-based treatments for pruritus are available. Topical therapy, oral histamine H(1) receptor antagonists, and phototherapy with UV radiation can target pruritus elicitation in the skin, whereas antiepileptic drugs, opioid receptor antagonists, and antidepressants can block signal processing in the CNS.

  16. [The notion of occupational skin disease. Medical and legal aspects].

    Science.gov (United States)

    Elsner, P; Schliemann, S

    2015-03-01

    The different definitions of skin disease in medicine and in law are frequently confusing for dermatologists. While a skin disease may be defined medically referring to the definition of health by the WHO as a pathological condition of the skin leading to a disruption of the physical, mental and social well-being of the individual, legal definitions vary depending on the field of insurance law that is referred to. In the law of private health insurance, a skin disease is defined as an anomalous condition of the skin requiring medical treatment that exists independently of the subjective judgement of the insured person and needs to be objectively confirmed by a medical evaluation. In contrast, in the law of the social health insurance, the Federal Court of Social Justice defines disease as irregular physical or mental condition, deviating from the perception of a healthy human being that requires medical treatment or leads to inability to work. Substantial bodily disfigurement may be regarded as an irregular physical condition. In the law of the statutory accident insurance, occupational skin diseases are defined under clause 5101 of the occupational disease regulation as serious or repeatedly relapsing skin diseases that have forced a person to refrain from any work activities causal for the development, the aggravation or the recurrence of the disease. The Federal Court of Social Justice interprets the term "skin disease" from the protective purpose of the law, i.e. the protection against the economic and health consequences of the exposure to harmful agents and a thereby forced change of profession. This broad interpretation of the term "skin disease" leads to the recognition of diseases of the conjunctiva of the eye or diseases of the blood vessels of the skin due to cold damage as skin diseases according to clause 5101. For the correct treatment and possibly notification of occupational skin diseases in collaboration with various insurance carriers

    1988-12-01

    In 1982 physicians at a hospital melanoma clinic in Montreal noticed that among their patients there had been seven men working in a single telecommunications company. This raised suspicions that working in that industry might be associated with development of malignant melanoma of the skin (MMS). A preliminary gross comparison with general population rates indicated that there was an increased risk in this working group. To estimate the risk of MMS more accurately, a standardised incidence ratio (SIR) was calculated based on the rates of MMS in the local population of the Greater Metropolitan Montreal Area for the years 1976-83. During that period, among workers in all plants for the company, 10 male cases of MMS were observed for an expected number of 3.7 (SIR = 2.7; 95% CI = 1.31-5.02). No cases were observed among female workers (expected = 1.3). The excess was significant among cases with a short latency (less than 20 years since beginning of employment). There was no apparent pattern of exposure based on job titles or departments.

    Skin diseases affect 30-70% of the world population, and globally, skin cancer rates are continuously increasing. In this respect, prevention programs and early detection of skin diseases are of particular importance. To screen sewer workers for skin diseases with regard to their work-related risk. Employees of the municipal utilities in Munich (Münchner Stadtentwässerung) underwent a whole-body examination of the skin, conducted by two dermatologists. In addition, all employees completed a paper-based questionnaire on risk behavior and preventive measures. We examined 81 employees (79 men, 2 women, mean age 45.7 ± 9.5 years). Skin lesions in need of treatment were found in 30.9% (n = 25): the most frequent diagnosis was mycosis pedis (16.1%). In addition, one employee was diagnosed with basal cell carcinoma and two with actinic keratoses. According to the questionnaire, 43.5% of the employees had undergone a physician-led skin cancer screening in the past, whereas sun-protection practices were rarely applied. According to our findings, employee skin cancer screening seems to be beneficial for the detection of work-related skin diseases and is associated with a high participation rate. Furthermore, the study suggests that sewer workers have a high rate of mycosis pedis, possibly a work-related effect.

    Baccarani, M; Bosi, A.; Papa, G.

    1980-01-01

    Six hundred and thirteen consecutive patients with Hodgkin's disease (HD), with a follow-up of two to ten years, were reviewed with the aim of establishing the type and frequency of second malignancies. Acute non-lymphoid leukemia developed in 2 of 152 patients treated by chemotherapy (CHT), and in 5 of 344 patients treated by CHT and radiotherapy (RT). Leukemia developed 12 to 83 months after diagnosis of HD, was always preceded by a preleukemic phase (3 to 25 months), and was always fatal (after 1 to 12 months). The karyotype of leukemic cells was studied in 4 of 7 patients and was always abnormal. Solid tumors developed in 1 of 152 patients treated by CHT, and in 4 of 344 patients treated by CHT and RT. The tumors appeared 10 to 63 months after diagnosis of HD and killed all 5 patients after 10 to 16 months. For patients treated by CHT, the actuarial frequency of leukemia and other tumors seven years after diagnosis of HD was 2.0% and 1.26%, respectively. For patients treated by CHT and RT, the figures were 2.04% and 2.26%, respectively. Second malignancies were not recorded among 117 patients treated by RT alone. These data are consistent with a relationship of acute leukemia to therapy for HD

    1990-01-01

    Growth failure due to endocrine dysfunction as a result of treatment for malignant disease is becoming increasingly common. It may occur after cranial or craniospinal irradiation given in the treatment of acute lymphoblastic leukemia and brain tumors, and is often coupled with early or precocious puberty. It also occurs after neck and gonadal radiation and is particularly severe after total body irradiation where multiple endocrine deficiencies frequently occur. Failure to appreciate its occurrence or failure to institute therapy early enough may lead to short stature in adult life. Accurate and regular monitoring of standing and sitting height, bone age, and endocrine data should be undertaken by the oncologist in close collaboration with an endocrinologist, to ensure appropriate management of the patient. 17 references

    The purpose of this preliminary study was to determine the incidence of second malignancies after combined-modality therapy for adults with Hodgkin disease and relate it to the details of initial treatment. We retrospectively studied 286 patients ranging in age from 16 to 88 years with stage I or II Hodgkin disease who were treated between 1980 and 1995 with chemotherapy followed 3 to 4 weeks later by radiotherapy. Patients received a median of three cycles of induction chemotherapy. Mitoxantrone, vincristine, vinblastine, and prednisone was used in 161 cases, mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) in 67 cases, Adriamycin, bleomycin, vinblastine, and dacarbazine in 19 cases, lomustine, vinblastine, procarbazine, and prednisone/doxorubicin, bleomycin, dacarbazine, and lomustine in 18 cases, and other chemotherapeutic regimens in the remaining 21 cases. The median radiotherapy dose was 40 Gy given in 20 daily 2-Gy fractions. Median follow-up of surviving patients was 7.4 years. There were 2,230 person-years of observation. Significantly increased relative risks (RR) were observed for acute myeloid leukemia (RR, 69.3; 95% CI, 14.3-202.6) and melanoma (RR, 7.3; 95% CI, 1.5-21.3). The 5-, 10-, and 15-year actuarial risks of acute myeloid leukemia were 0.8%, 1.3%, and 1.3%, respectively. Patients treated with MOPP had the highest 15-year actuarial risk of leukemia (1.6%). The 5-, 10-, and 15-year actuarial risks of solid tumors were 1.9%, 9.3%, and 16.8%, respectively. Consolidative radiotherapy to both sides of the diaphragm resulted in a trend toward an increased risk of solid tumors relative to radiotherapy to only one side of the diaphragm (p = 0.08). In an effort to reduce the risk of second malignancies, we have stopped using the alkylating agents nitrogen mustard and procarbazine and elective paraaortic and splenic radiotherapy after chemotherapy.

The most prominent relative epidemiological increase has been disclosed in young women. The aim of the study was to assess the effects of chronic sun exposures in order to rate the extend of melanocytic stimulations in the vicinity of CMM. Methods: The study was designed to evaluate the melanin distribution and density using ultraviolet light illumination. The present study was performed on surgical excision specimens of thin CMM lesion removed from the upper limbs of 55 Caucasian adults (37 women and 18 men. Two control groups comprised 23 men and 21 women of similar ages who had medium-size congenital melanocytic nevi, also present on the upper limbs. The peritumoral skin was scrutinized using a Visioscan® VC98 device, revealing the faint mosaic melanoderma (FMM pattern that grossly indicates early signs of chronic photodamage in epidermal melanin units. Results: The median extent of relative FMM was significantly higher in the CMM male group. By contrast, the CMM female group showed a reverse bimodal distribution in FMM size. Only 12/37 (32.5% of the CMM female group had an increased FMM size, whereas 25/37 (67.5% of females with CMM had a global FMM extent in the normal range, relative to the controls. Conclusion: Thin CMM supervening in young women appear unrelated to repeat

  5. The superior vena cava syndrome caused by malignant disease

    Objective: The superior vena cava (SVC) obstruction by malignant diseases is either by direct invasion and compression or by tumour thrombus of the SVC. Whatever is its cause, obstruction of the SVC causes elevated pressure in the veins draining into the SVC and increased or reversed blood flow through collateral vessels. Severity of the syndrome depends on the collateral vascular system development. Therefore, imaging of the collateral veins with variable location and connection is important in determining the extension and management of the disease. Our aims are to describe collateral vessels of the superior vena cava syndrome (SVCS) related with the malignant diseases and to assess the ability of multi-detector row CT with multiplanar and 3D volume rendering techniques in determining and describing collateral circulations. Materials and methods: We present CT angiography findings of seven patients with small cell carcinoma of the lung (n = 2), squamous cell carcinoma of the lung (n = 3), Hodgkin disease of the thorax (n = 1), and squamous cell carcinoma of the oesophagus (n = 1). The patients received contrast-enhanced CT scans of the chest and abdomen on a multi-detector row CT during breath holding at suspended inspiration. Results: CT images revealed the cause and level of the SVC obstruction in all patients with axial and multiplanar reconstructed images. The SVC showed total obstruction in five patients and partial obstruction in two patients. The most common experienced collateral vessels were azygos vein (6), intercostal veins (6), mediastinal veins (6), paravertebral veins (5), hemiazygos vein (5), thoracoepigastric vein (5), internal mammary vein (5), thoracoacromioclavicular venous plexus (5), and anterior chest wall veins (5). While one case showed the portal-systemic shunt, V. cordis media and sinus coronarius with phrenic veins were enlarged in two cases, and the left adrenal vein was enlarged in a patient.

    Objective: The superior vena cava (SVC) obstruction by malignant diseases is either by direct invasion and compression or by tumour thrombus of the SVC. Whatever is its cause, obstruction of the SVC causes elevated pressure in the veins draining into the SVC and increased or reversed blood flow through collateral vessels. Severity of the syndrome depends on the collateral vascular system development. Therefore, imaging of the collateral veins with variable location and connection is important in determining the extension and management of the disease. Our aims are to describe collateral vessels of the superior vena cava syndrome (SVCS) related with the malignant diseases and to assess the ability of multi-detector row CT with multiplanar and 3D volume rendering techniques in determining and describing collateral circulations. Materials and methods: We present CT angiography findings of seven patients with small cell carcinoma of the lung (n = 2), squamous cell carcinoma of the lung (n = 3), Hodgkin disease of the thorax (n = 1), and squamous cell carcinoma of the oesophagus (n = 1). The patients received contrast-enhanced CT scans of the chest and abdomen on a multi-detector row CT during breath holding at suspended inspiration. Results: CT images revealed the cause and level of the SVC obstruction in all patients with axial and multiplanar reconstructed images. The SVC showed total obstruction in five patients and partial obstruction in two patients. The most common experienced collateral vessels were azygos vein (6), intercostal veins (6), mediastinal veins (6), paravertebral veins (5), hemiazygos vein (5), thoracoepigastric vein (5), internal mammary vein (5), thoracoacromioclavicular venous plexus (5), and anterior chest wall veins (5). While one case showed the portal-systemic shunt, V. cordis media and sinus coronarius with phrenic veins were enlarged in two cases, and the left adrenal vein was enlarged in a patient. In one case, the azygos vein with reversed

    An incidence study of malignant melanoma of the skin (MMS), conducted previously among the workers of four plants of a large telecommunications industry located in Montreal, Canada, showed a standardised incidence ratio of 2.7 (95% confidence interval (95% CI) 1.3-5.02) for the years 1976 to 1983. To describe more precisely the magnitude of the problem a mortality study was started among the same population (n = 9590) for the same period (1976-83). At the end of 1983, 9180 workers were alive, 261 were dead, and 149 (1.5%) were not traced. Standardised mortality ratios (SMRs) for all causes of death were surprisingly low for men (SMR = 0.57; 95% CI 0.50-0.64) and women (SMR = 0.56; 95% CI 0.37-0.82). The SMRs for major causes of death were also less than expected. These results may be explained by a pronounced selection bias (healthy worker effect) and by the short duration of follow up (eight years). For MMS, two deaths occurred among men (SMR = 2.00; 95% CI 0.24-7.22) and one among women (SMR = 4.81; 95% CI 0.12-26.78). A third man who died of MMS was miscoded as having a primary pulmonary melanoma. Including this case increased the SMR for MMS to 3.00 (95% CI 0.62-8.77; p = 0.08). Polyvinyl chloride and polychlorinated biphenyls were used in the plants and some of the workers did soldering. A planned case-control study will investigate other possible exposures at work.

    Early detection of several skin-related neglected tropical diseases (skin NTDs)-including leprosy, Buruli ulcer, yaws, and scabies- may be achieved through school surveys, but such an approach has seldom been tested systematically on a large scale in endemic countries. Additionally, a better understanding of the spectrum of skin diseases and the at-risk populations to be encountered during such surveys is necessary to facilitate the process. We performed a school skin survey for selected NTDs and the spectrum of skin diseases, among primary schoolchildren aged 5 to 15 in Côte d'Ivoire, West Africa. This 2-phase survey took place in 49 schools from 16 villages in the Adzopé health district from November 2015 to January 2016. The first phase involved a rapid visual examination of the skin by local community healthcare workers (village nurses) to identify any skin abnormality. In a second phase, a specialized medical team including dermatologists performed a total skin examination of all screened students with any skin lesion and provided treatment where necessary. Of a total of 13,019 children, 3,504 screened positive for skin lesions and were listed for the next stage examination. The medical team examined 1,138 of these children. The overall prevalence of skin diseases was 25.6% (95% CI: 24.3-26.9%). The predominant diagnoses were fungal infections (n = 858, prevalence: 22.3%), followed by inflammatory skin diseases (n = 265, prevalence: 6.9%). Skin diseases were more common in boys and in children living along the main road with heavy traffic. One case of multi-bacillary type leprosy was detected early, along with 36 cases of scabies. Our survey was met with very good community acceptance. We carried out the first large-scale integrated, two-phase pediatric multi-skin NTD survey in rural Côte d'Ivoire, effectively reaching a large population. We found a high prevalence of skin diseases in children, but only limited number of skin NTDs. With the lessons learned

    Skin diseases and their complications are a significant burden on the nation, both in terms of acute and chronic morbidities and their related expenditures for care. Because accurately calculating the cost of skin disease has proven difficult in the past, we present here multiple comparative techniques allowing a more expanded approach to estimating the overall economic burden. Our aims were to (1) determine the economic burden of primary diseases falling within the realm of skin disease, as defined by modern clinical disease classification schemes and (2) identify the specific contribution of each component of costs to the overall expense. Costs were taken as the sum of several factors, divided into direct and indirect health care costs. The direct costs included inpatient hospital costs, ambulatory visit costs (further divided into physician's office visits, outpatient department visits, and emergency department visits), prescription drug costs, and self-care/over-the-counter drug costs. Indirect costs were calculated as the outlay of days of work lost because of skin diseases. The economic burden of skin disease in the United States is large, estimated at approximately $35.9 billion for 1997, including $19.8 billion (54%) in ambulatory care costs; $7.2 billion (20.2%) in hospital inpatient charges; $3.0 billion (8.2%) in prescription drug costs; $4.3 billion (11.7%) in over-the-counter preparations; and $1.6 billion (6.0%) in indirect costs attributable to lost workdays. Our determination of the economic burden of skin care in the United States surpasses past estimates several-fold, and the model presented for calculating cost of illness allows for tracking changes in national expenses for skin care in future studies. The amount of estimated resources devoted to skin disease management is far more than required to treat conditions such as urinary incontinence ($16 billion) and hypertension ($23 billion), but far less than required to treat musculoskeletal

    The mortality burden from nonneoplastic skin disease in the United States is unknown. We sought to estimate mortality from nonneoplastic skin disease as underlying and contributing causes of death. Population-based death certificate data detailing mortality from nonneoplastic skin disease for years 1999 to 2009 were used to calculate absolute numbers of death and age-adjusted mortality by year, patient demographics, and 10 most commonly reported diagnoses. Nonneoplastic skin diseases were reported as underlying and contributing causes of mortality for approximately 3948 and 19,542 patients per year, respectively. Age-adjusted underlying cause mortality (per 100,000 persons) were significantly greater (P deaths occurred in patients ages 65 years and older (34,248 total deaths). Common underlying causes of death included chronic ulcers (1789 deaths/y) and cellulitis (1348 deaths/y). Errors in death certificate data and inability to adjust for patient-level confounders may limit the accuracy and generalizability of our results. Mortality from nonneoplastic skin disease is uncommon yet potentially preventable. The elderly bear the greatest burden of mortality from nonneoplastic skin disease. Chronic ulcers and cellulitis constitute frequent causes of death. Copyright © 2013 American Academy of Dermatology, Inc. Published by Mosby, Inc. All rights reserved.

    Skin cancer is the most common malignant tumors in human. Therapeutic modalities of the skin cancers are local destruction, radiotherapy and surgery. External radiation therapy leads to good results, however, overall 5-6 weeks of treatment period is needed to deliver optimal radiation dose to tumors. In this study, β-emitting radionuclide, Ho-166, impregnated in a specially designed patch was utilized to superficial skin cancers and Bowen's disease for local irradiation. Methods; Animal study was employed in 10 mice with chemically induced skin tumors. Five- mm size patches containing 22.2 -72.15 MBq(0.6 - 1.95 mCi) of Ho-166 were applied to the tumor surface for 1 -2 hr. In clinical trial, patients with squamous carcinoma(n=3), basal cell carcinoma(n=1), and Bowen's disease(n=1) were treated with patches containing 273.8 - 999 MBq (7.4 - 27 mCi) of Ho-166 for 30 minutes to 1 hour. Pathologic examination was performed 4 - 7 weeks after the treatment in animal model. Skin biopsy was performed 8 weeks post-treatment in four patients. Results; Tumor destruction was seen 1 week post the treatment, however, radiation dermatitis or ulceration developed at the site of radionuclide application. Those reactions healed gradually with fibrosis or epithelialization, which was confirmed pathologically. No significant adverse reaction to radiation except subcutaneous fibrosis was found. Conclusion; Superficial skin tumors could be successfully treated by topical application of β-emitting radionuclides. (author)

    In order to assess the utility of 67gallium citrate in delineating malignant pleural mesothelioma from benign asbestos-related pleural disease, 49 patients with malignant mesothelioma and 16 with benign asbestos-related pleural disease were studied. Seven patients with malignant mesothelioma had no history of asbestos exposure, while the remaining 58 patients were exposed. Forty-three of the 49 patients (88%) with malignant mesothelioma had a positive 67gallium scan including 36 of the 42 (86%) patients with asbestos exposure and all 7 patients without a history of asbestos exposure. Three of 16 patients (19%) with benign asbestos-related pleural disease had a positive scan. 67Gallium radionuclide imaging is nonspecific but may be valuable in noninvasive monitoring of asbestos-exposed populations, which have a high risk for the late development of benign and/or malignant pleural disease

    Full Text Available Patients suffering from endocrine disorders often present a wide profile of skin lesions. In hyperthyroidism we observe hair loss, lower leg myxedema and onycholysis or, in the case of hormone deficiency, generalized swelling of the skin, which becomes cold and pale. Primary hyperparathyroidism is revealed by pruritus, presence of chronic urticaria or deposition of amorphous calcium salts. In hypoparathyroidism, the skin is dry while the nails become very brittle. Skin lesions in diabetes include necrobiosis lipoidica, granuloma annulare, scleroderma-like diabetic edema and acanthosis nigricans. Overactive pituitary gland is often manifested as acromegaly with hypertrophy of soft tissue thickening and hypertrichosis. The skin in the early stages of hypopituitarism feels swollen, is pale yellow and oily, and finally becomes alabaster and dry. The characteristic features of Cushing syndrome are central obesity, lunar face, buffalo hump, and striae. In Addison’s disease we observe hyperpigmentation. Hyperandrogenism in women leads to acne, hirsutism and virilization.

  3. Functional protease profiling for diagnosis of malignant disease.

    2012-01-01

    Clinical proteomic profiling by mass spectrometry (MS) aims at uncovering specific alterations within mass profiles of clinical specimens that are of diagnostic value for the detection and classification of various diseases including cancer. However, despite substantial progress in the field, the clinical proteomic profiling approaches have not matured into routine diagnostic applications so far. Their limitations are mainly related to high-abundance proteins and their complex processing by a multitude of endogenous proteases thus making rigorous standardization difficult. MS is biased towards the detection of low-molecular-weight peptides. Specifically, in serum specimens, the particular fragments of proteolytically degraded proteins are amenable to MS analysis. Proteases are known to be involved in tumour progression and tumour-specific proteases are released into the blood stream presumably as a result of invasive progression and metastasis. Thus, the determination of protease activity in clinical specimens from patients with malignant disease can offer diagnostic and also therapeutic options. The identification of specific substrates for tumour proteases in complex biological samples is challenging, but proteomic screens for proteases/substrate interactions are currently experiencing impressive progress. Such proteomic screens include peptide-based libraries, differential isotope labelling in combination with MS, quantitative degradomic analysis of proteolytically generated neo-N-termini, monitoring the degradation of exogenous reporter peptides with MS, and activity-based protein profiling. In the present article, we summarize and discuss the current status of proteomic techniques to identify tumour-specific protease-substrate interactions for functional protease profiling. Thereby, we focus on the potential diagnostic use of the respective approaches. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    A cream formulation containing high concentrations (10%) of a standard mixture of solasodine glycosides (BEC) has been shown to be effective in the treatment of malignant and benign human skin tumours. We now report that a preparation (Curaderm) which contains very low concentrations of BEC (0.005%) is effective in the treatment of keratoses, basal cell carcinomas (BCCs) and squamous cell carcinomas (SCCs) of the skin of humans. In an open study, clinical and histological observations indicated that all lesions (56 keratoses, 39 BCCs and 29 SCCs) treated with Curaderm had regressed. A placebo formulation had no effect on a smaller number of treated lesions. Curaderm had no adverse effect on the liver, kidneys or haematopoietic system.

    Today, Android is one of the most widely used operating system in the world. Most of android device has a camera that could capture an image, this feature could be optimized to identify skin disease. The disease is one of health problem caused by bacterium, fungi, and virus. The symptoms of skin disease usually visible. In this work, the symptoms that captured as image contains HSV in every pixel of the image. HSV can extracted and then calculate to earn euclidean value. The value compared using nearest neighbor algorithm to discover closer value between image testing and image training to get highest value that decide class label or type of skin disease. The testing result show that 166 of 200 or about 80% is accurate. There are some reasons that influence the result of classification model like number of image training and quality of android device’s camera.

    In daily practice, ultrasonography (US) is used only to designate the location and pattern of venous lesions. Skin US is not performed between routine venous investigations. Skin morphology is evaluated by the same probes used for routine Duplex evaluation of superficial veins. US findings from evident skin lesions are comparatively evaluated with those from the surrounding apparently normal skin and from the contralateral leg. Inflammation and dermal edema can be found in the apparently normal skin of C2 legs. Swollen legs show thickening of the subcutaneous layer as a result of diffuse soaking or anechoic cavities, with or without dermal edema. Chronic hypodermitis is characterized by inflammatory edema in initial phases, and by liposclerosis in advanced cases. Recrudescence of inflammation provokes focal rarefactions of the subcutaneous layer, possibly related to ulcer opening. In legs with venous disorders, sonography refines clinical evaluation of the skin and may reveal changes not highlighted by inspection. Some of these changes could require further investigation because they have not yet been explained or described. Skin sonography should improve knowledge of the natural history of skin changes, as well as contribute to a better grading of venous diseases severity In particular, US evidence of cutaneous and subcutaneous changes in C2 legs should be considered to stratify the treatment in C2 legs, by identifying those in which varicose veins are not simply a cosmetic problem.

    Inhibitors of mutant BRAF are emerging as standard of care in patients with metastatic melanoma who carry relevant oncogenic mutations. However, BRAF inhibitors are found to induce cutaneous squamous cell carcinoma (cuSCC). Population-based background rates of cuSCC and non-cutaneous squamous cell carcinoma (non-cuSCC) in the metastatic melanoma population may contextualize safety signals from randomized clinical trials or the clinics. However, these background rates are lacking. We conducted a historical cohort study to evaluate the background rates of new-onset non-melanoma skin lesions and non-cuSCC among 2,814 metastatic malignant melanoma patients diagnosed in 1997-2010, identified through the Danish Cancer Registry and the National Pathology Registry. Patients were excluded if they had a history of cancer before the metastatic melanoma diagnosis, other than skin cancers. We determined the incidence of non-melanoma malignant skin lesions and non-cuSCC that occurred post metastatic melanoma diagnosis, censoring patients at death, emigration, or December 31, 2011 (end of study period), whichever came first. The median age at metastatic melanoma diagnosis was 64 years. Over 40% of patients died within one year of metastatic diagnosis and ~70% died within 5 years. The percentages of patients with prior history or prevalent disease at metastatic melanoma diagnosis included: 8.6% with cuSCC or basal cell carcinoma (BCC), 3.9% with actinic keratosis (AK), and 0.7% with Bowen's disease. No patients had past or current non-cuSCC per study exclusion criterion. The incidence of non-melanoma skin lesions during the 6 months post-metastatic melanoma diagnosis was as follows: BCC, 1.8% (42.5 per 1000 person-years [PY]); AK, 0.8% (18.6 per 1000 PY); cuSCC, 0.1% (1.7 per 1000 PY); Bowen's disease, 0.04% (0.8 per 1000 PY); and keratoacanthoma (KA), 0%.

    Full Text Available CONTEXT: Malnutrition is frequently observed in inpatients with malignant diseases and may contribute to longer hospital stays. OBJECTIVE: To compare the nutritional status, lymphocyte count, hemoglobin values and length of hospital stay of patients with and without malignant diseases. METHODS: This comparative study assessed indicators of nutritional status, namely body mass index, recent weight loss, lymphocyte count, hemoglobin and length of hospital stay, of 928 surgical patients with and without malignant diseases (50.2% females and 49.8% males. The chi-square test was used to compare proportions and the Mann-Whitney test was used to compare continuous measurements between two groups. The significance level was set at 5%. RESULTS: Patients with malignant diseases had longer hospital stays (P<0.0001, furthermore, a higher percentage of patients with malignant diseases had body mass index <18.5 (P<0.0001 and experienced recent weight changes (P<0.0002. Lymphocyte count also differed statistically between the groups (P = 0.0131, which lower levels were identified among patients with malignant diseases. CONCLUSION: The lymphocyte count, hemoglobin values and weight loss are important findings of nutritional depletion in patients with malignant diseases.

    There are limited data on skin lesions in children with end-stage renal failure. The aim of the study was an evaluation of the skin barrier in children with different stages of chronic kidney disease (CKD). The prevalence of xerosis, its severity, as well as its link selected demographic factors, were examined. The study included 103 children: 72 with CKD stages 3-5 (38 on conservative treatment and 34 on dialysis) and 31 patients with primary monosymptomatic nocturnal enuresis as a control group. Initially, the study subjects described the localisation and severity of dry skin by themselves. Next, clinical evaluation of xerosis, non-invasive corneometric assessment of epidermis moisturising and the measurement of transepidermal water loss were performed. Most CKD children reported dry skin. The problem of xerosis was identified more frequently in patients on dialysis (67.6 %) than on conservative treatment (42.1 %) (p = 0.01). CKD patients divided according to skin dryness did not differ with regards to age, sex, initial kidney disease and CKD duration. Disturbed skin barrier is an important concern of children with CKD, intensifying as the disease progresses. This symptom occurs on early stages of CKD and it should be taken into consideration in the CKD management.

    Generalized peeling skin disease is an autosomal-recessive ichthyosiform erythroderma characterized by lifelong patchy peeling of the skin. After genome-wide linkage analysis, we have identified a homozygous nonsense mutation in CDSN in a large consanguineous family with generalized peeling skin, pruritus, and food allergies, which leads to a complete loss of corneodesmosin. In contrast to hypotrichosis simplex, which can be associated with specific dominant CDSN mutations, peeling skin disease is characterized by a complete loss of CDSN expression. The skin phenotype is consistent with a recent murine Cdsn knockout model. Using three-dimensional human skin models, we demonstrate that lack of corneodesmosin causes an epidermal barrier defect supposed to account for the predisposition to atopic diseases, and we confirm the role of corneodesmosin as a decisive epidermal adhesion molecule. Therefore, peeling skin disease will represent a new model disorder for atopic diseases, similarly to Netherton syndrome and ichthyosis vulgaris in the recent past.

    Purpose: To evaluate MR imaging and CT in differentiating malignant pleural mesothelioma from other malignancies or benign pleural disease. Material and Methods: Thirty-four patients (18 pleural mesothelioma, 9 other malignancies, 7 benign pleural diseases) were examined using enhanced CT and MR. Two radiologists reviewed the CT and two others the MR images. Comparisons were made between the diagnostic groups and the imaging methods. Results: The abnormalities commonly found in malignant disease, but significantly less frequently in benign pleural disease, were focal thickening and enhancement of inter lobar fissures. In mesothelioma, enhancement of inter lobar fissures, tumour invasion of the diaphragm, mediastinal soft tissue or chest wall, were significantly more often observed than in other malignancies and MR was the most sensitive method. In other malignancies, invasion of bony structures was a more common finding and was also better shown by MR. The contrast-enhanced T1 fat-suppressed (CET1fs) sequence detected these features better than other MR sequences. Conclusion: MR, especially the CET1fs sequence in three planes, gave more information than enhanced CT. Focal thickening and enhancement of inter lobar fissures were early abnormalities indicating malignant pleural disease. MR could be clinically useful for differentiating mesothelioma from other pleural diseases

    Epigenetic inactivation of tumor-related genes is an important characteristic in the pathology of human cancers, including melanomagenesis. We analyzed the epigenetic inactivation of Claudin 11 (CLDN11) in malignant melanoma (MM) of the skin, including six melanoma cell lines, 39 primary melanoma, 41 metastases of MM and 52 nevus cell nevi (NCN). CLDN11 promoter hypermethylation was found in 19 out of 39 (49%) of the primary MM and in 21 out of 41 (51%) of the MM metastases, but only in eight out of 52 (15%) of NCN (p = 0.001 and p = 0.0003, respectively). Moreover, a significant increase in the methylation level of CLDN11 from primary melanomas to MM metastases was revealed (p = 0.003). Methylation of CLDN11 was significantly more frequent in skin metastases (79%) compared to brain metastases (31%; p = 0.007). CLDN11 methylation was also found in five out of six MM cell lines (83%) and its promoter hypermethylation correlated with a reduced expression. Treatment of MM cell lines with a DNA methylation inhibitor reactivated CLDN11 transcription by its promoter demethylation. In summary, CLDN11 proved to be an epigenetically inactivated tumor related gene in melanomagenesis, and analysis of CLDN11 methylation level represents a potential tool for assisting in the discrimination between malignant melanoma and nevus cell nevi.

    The thyroid gland was one of the first organs imaged in nuclear medicine, beginning in the 1940s. Thyroid scintigraphy is based on a specific phase or prelude to thyroid hormone synthesis, namely trapping of iodide or iodide analogues (ie, Tc99m pertechnetate), and in the case of radioactive iodine, eventual incorporation into thyroid hormone synthesis within the thyroid follicle. Moreover, thyroid scintigraphy is a reflection of the functional state of the gland, as well as the physiological state of any structure (ie, nodule) within the gland. Scintigraphy, therefore, provides information that anatomical imaging (ie, ultrasound, computed tomography [CT], magnetic resonance imaging) lacks. Thyroid scintigraphy plays an essential role in the management of patients with benign or malignant thyroid disease. In the former, the structure or architecture of the gland is best demonstrated by anatomical or cross-sectional imaging, such as ultrasound, CT, or even magnetic resonance imaging. The role of scintigraphy, however, is to display the functional state of the thyroid gland or that of a clinically palpable nodule within the gland. Such information is most useful in (1) patients with thyrotoxicosis, and (2) those patients whose thyroid nodules would not require tissue sampling if their nodules are hyperfunctioning. In neoplastic thyroid disease, thyroid scintigraphy is often standard of care for postthyroidectomy remnant evaluation and in subsequent thyroid cancer surveillance. Planar radioiodine imaging, in the form of the whole-body scan (WBS) and posttherapy scan (PTS), is a fundamental tool in differentiated thyroid cancer management. Continued controversy remains over the utility of WBS in a variety of patient risk groups and clinical scenarios. Proponents on both sides of the arguments compare WBS with PTS, thyroglobulin, and other imaging modalities with differing results. The paucity of large, randomized, prospective studies results in dependence on consensus

  2. Magnetic resonance imaging in diffuse malignant bone marrow diseases

    Nyman, R.; Rehn, S.; Glimelius, B.; Hagberg, H.; Hemmingsson, A.; Jung, B.; Simonsson, B.; Sundstroem, C.

    Twenty-four patients with malignant bone marrow involvement or polycythemia vera, 8 patients with reactive bone marrow and 7 healthy individuals were examined with spin-echo magnetic resonance imaging at 0.35 T and 0.5 T. Signs of an increased longitudinal relaxation time, T1, were found when normal bone marrow was replaced by malignant cells, polycythemia vera or reactive marrow. A shortened T1 was indicated in 4 patients in bone marrow regions treated by radiation therapy; the marrow was most likely hypocellular in these cases. The estimated T1 relaxation times were highly correlated to the cellularity of the bone marrow as assessed by histology. Among patients with close to 100% cellularity neither T1 nor T2 discriminated between the various malignancies or between malignant and reactive, non-malignant bone marrow. Characterization of tissues in terms of normalized image intensities was also attempted, the motive being to avoid approximations and uncertainties in the assessment of T1 and T2. The normalization was carried out with respect to the image of highest intensity, i.e. the proton density weighted image. The results were in agreement with those for T1 and T2. It was concluded that MRI is valuable for assessing bone marrow cellularity, but not for differentiating between various bone marrow disorders having a similar degree of cellularity.

    Full Text Available Arteriosclerosis is the basis of all cardiovascular diseases. Numerous risk factors lead to the rise of malignant and cardiovascular diseases. Those are: elevated artery blood pressure, raised plasma cholesterol and triglycerides, low level of HDL-cholesterol, smoking, diabetes mellitus, diet, lack of physical exercises, heredity, stress, gender.The aim of the study was to compare the lipid status of patients with cardiovascular disease or malignancy.The database of the biochemical laboratory and oncology counseling unit of the "Ostrog Clinic" was used. The method of random sample was used and patients (n=29 of both genders were selected, who were at the age of 40 to 47, with cardiovascular diseases, and had significant occlusive coronary disease, which required operation or surgical revascularization procedure. The patients were classified in two groups: G1 (n=14 with statin therapy and G2 (n=15 without statin therapy. Both groups were statistically compared with a group of female patients (n=30 with breast cancer, who were between 37 and 69 years of age. Control group comprised 25 healthy subjects. Standard statistical methods were used for processing the lipid status parameters, namely: the arithmetic mean, standard deviation SDn and SDn-1, correlation coefficient, post hock test and a single factor analysis of variance.The results obtained have pointed to the existence of a marked hyperlipoproteinemia type 4 in the group of cardiovascular patients who did not use statin (G2. In G2, higher levels of cholesterol, LDL-cholesterol and plasma triglycerides in comparison with the control and G1, while the value of HDL-cholesterol was within the range of referent values. The obvious suppressing effect of statin on cholesterol and LDL-cholesterol was observed in G1. Group G3 had, in comparison with the control and cardiovascular patients, significantly lower levels of cholesterol and triglycerides in plasma, as well as lower index of atherosclerosis

    Shoe manufacturing workers are exposed daily to an extensive range of potential physical and chemical occupational hazards. Shoe manufacturing in Indonesia is one of the industrial sectors that has shown sustained growth amongst the newly industrialized countries (NICs). In this study, we investigated the possible potential exposure of the workers to physical and occupational hazards and determined the prevalence of occupational skin diseases at a shoe manufacturing factory in Indonesia. A cross-sectional study on the observation of the working process and an inventory and risk assessment of exposure to the chemicals used. Classification of chemicals as potential sensitizers/irritants and qualitative assessments of these chemicals were done. Workers were examined and interviewed using the Nordic Occupational Skin Questionnaire-2002/LONG. The risk of Occupational skin diseases (OSD) at the shoe factory was mainly related to the exposure of the workers' skin to potential physical and chemical hazards in hot and humid environmental conditions. From a total of 514 workers, 8.5 % reported current OSD and 4.8 % reported a history of OSD. Occupational skin diseases were diagnosed in 29 % of the workers by dermatologists and 7.6 % had an occupational contact dermatitis (OCD). Of the 39 workers with contact dermatitis, 33 consented to being patch tested, 14 (3 %) workers showed a positive results and considered as having an occupational allergic contact dermatitis (OACD) and 25 (4.9 %) had an occupational irritant contact dermatitis (OICD). We observed a repeated and prolonged exposure of the workers to numerous physical and chemical skin hazards at this factory.

    Lipidomics is the large-scale profiling and characterization of lipid species in a biological system using mass spectrometry. The skin barrier is mainly comprised of corneocytes and a lipid-enriched extracellular matrix. The major skin lipids are ceramides, cholesterol and free fatty acids (FFA). Lipid compositions are altered in inflammatory skin disorders with disrupted skin barrier such as atopic dermatitis (AD). Here we discuss some of the recent applications of lipidomics in human skin biology and in inflammatory skin diseases such as AD, psoriasis and Netherton syndrome. We also review applications of lipidomics in human skin equivalent and in pre-clinical animal models of skin diseases to gain insight into the pathogenesis of the skin disease. Expert commentary: Skin lipidomics analysis could be a fast, reliable and noninvasive tool to characterize the skin lipid profile and to monitor the progression of inflammatory skin diseases such as AD.

    Background Celiac disease (CD) is associated with an increased risk of lymphoproliferative malignancy (LPM). It is unknown whether this risk is affected by the results of the follow-up intestinal biopsy, performed to document mucosal healing. Objective To examine the association between mucosal healing in CD and later LPM. Design Population-based cohort study Setting We identified patients with CD from all of Sweden’s 28 pathology departments. Patients Individuals with CD who had a follow-up biopsy after initial diagnosis. Measurements We compared the risk of LPM to that of the general population using expected rates; and through Cox regression we compared the rate of LPM in those with persistent villous atrophy to those with mucosal healing. Results Among 7,625 patients with CD and a follow-up biopsy, persistent villous atrophy was present in 3,308 (43%). The overall risk of LPM was increased compared to the general population (Standardized incidence ratio, SIR 2.81; 95%CI 2.10–3.67), but this increase was greater among those with persistent villous atrophy (SIR 3.78; 95%CI 2.71–5.12) as compared to those with mucosal healing (SIR 1.50; 95%CI 0.77–2.62). Persistent villous atrophy compared to mucosal healing was associated with an increased risk of LPM (Hazard ratio, HR 2.26; 95%CI 1.18–4.34). We found an increased risk of T cell lymphoma (HR 3.51; 95%CI 0.75–16.34), but no excess risk of B cell lymphoma (HR 0.97; 95%CI 0.21–4.49). Limitation We had no data on dietary compliance. Conclusions The increased LPM risk in CD is associated with the results of the follow-up biopsy, with a higher risk among those with persistent villous atrophy. Follow-up biopsy may be a means to effectively stratify CD patients regarding subsequent LPM risk.

    The aim of this study was to evaluate the associations between chronic inflammatory skin conditions and patients' emotional state and quality of life. The following self-rated questionnaires were used: Emotional State Questionnaire, a self-report scale assessing depression and anxiety symptoms; Dermatology Life Quality Index (DLQI); and RAND-36, a measure of health-related quality of life. The study group comprised 40 patients with psoriasis, 40 with eczema, 40 with acne, 15 with seborrhoeic dermatitis and 40 healthy controls. Patients with chronic skin diseases had lower DLQI and lower RAND-36 physical functioning scores, more perceived physical limitations and pain, and lower emotional well-being and general health ratings compared with the control group. In conclusion, chronic skin diseases are associated with symptoms of emotional distress, in particular insomnia and general anxiety.

Intact parathyroid hormone (Pskin autofluorescence after age (Pskin autofluorescence was associated with a 7.43-fold (95% confidence intervals, 3.59-15.37; PSkin autofluorescence retained significance in predicting CACS ≥400 (odds ratio, 3.63; 95% confidence intervals, 1.44-9.18; P=0.006) when adjusting for age, sex, serum calcium, phosphate, albumin, C-reactive protein, lipids, blood pressure, estimated glomerular filtration rate, and intact parathyroid hormone but marginally lost significance when additionally adjusting for diabetes mellitus (odds ratio, 2.23; 95% confidence intervals, 0.81-6.14; P=0.1). Combination of diabetes mellitus and higher intact parathyroid hormone was associated with greater skin autofluorescence and CACS versus those without diabetes mellitus and having lower intact parathyroid hormone. Tissue advanced glycation end product, as reflected by skin autofluorescence, showed a significant novel association with vascular calcification in chronic kidney disease. These data suggest that increased tissue advanced glycation end product may contribute to vascular calcification in chronic kidney disease and diabetes mellitus and warrant further experimental investigation. © 2014 American Heart Association, Inc.

  19. Radioimmunotherapy for malignant diseases. Current contributions and future options

    International Nuclear Information System (INIS)

    Mahe, M.A.; Chatal, J.F.

    1995-01-01

    Radioimmunotherapy is based on the use of radioactive agents (iodine 131, yttrium 90), murine-derived monoclonal antibodies and specific tumour-related membrane antigens. This new treatment modality was applied in 800 patients with different types of malignant tumours which had not responded to traditional therapy. Among the haematologic tumours, the most promising results were obtained in B phenotype non-Hodgkin lymphoma. More modest results were obtained for solid tumours although good results were observed after intraperitoneal administration in patients with cancer of the ovary. The main side effects are acute reversible anaphylactic shock, haematologic toxicity and development of anti-murine human antibodies. Several methods are currently under study to increase irradiation dose delivered at the tumoural site since less than 1% of the injected radioactive dose is absorbed by tumoural cells. Several clinical studies are to be conducted in France, particularly for malignant non-Hodgkin lymphoma and cancer of the ovary. (authors). 31 refs

    To compare the galactographic findings of malignant and benign disease in patients with pathologic nipple discharge and to analyze the features suggesting malignancy. In 24 patients in whom pathologic nipple discharge had occurred, the findings of preoperative galactography were correlated with those of pathology. Nine of the 24 cases were malignant and the other 15 were benign. Intraductal calcification occurred in five malignant cases (56%) and two (13%) which were benign. Seven malignant cases (78%) involved the segmental ducts, and in eight (89%), the peripheral ducts below the subsegmental duct were involved. Five benign cases (33%) involved the lactiferous sinus, seven (47%) the segmental duct, and two (13%) the subsegmental duct. Distal duct dilatation occurred in four benign cases (27%), while ductal stenosis was noted in six cases (67%) and ductal distortion in seven (78%). A malignant tumor appeared as a multiple (n=5, 56%) or irregular (n=5, 56%) filling defect, and a benign tumor as a single (n=12, 80%), oval (n=6, 40%) or lobular (n=4, 27%) filling defect. At galactography, a malignant tumor frequently appeared as an irregular multiple intraductal filling defect in a peripheral duct. A benign tumor, on the other hand, appeared as an oval or lobular single lesion. The presence of ductal stenosis, distortion and intraductal microcalcifications not opacified by contrast material suggest possible malignancy.

    Peptides play decisive roles in the skin, ranging from host defense responses to various forms of neuroendocrine regulation of cell and organelle function. Synthetic peptides conjugated to radionuclides or photosensitizers may serve to identify and treat skin tumors and their metastatic forms in other organs of the body. In the introductory part of this review, the role and interplay of the different peptides in the skin are briefly summarized, including their potential application for the management of frequently occurring skin cancers. Special emphasis is given to different targeting options for the treatment of melanoma and melanotic lesions. Radionuclide Targeting: α-Melanocyte-stimulating hormone (α-MSH) is the most prominent peptide for targeting of melanoma tumors via the G protein-coupled melanocortin-1 receptor that is (over-)expressed by melanoma cells and melanocytes. More than 100 different linear and cyclic analogs of α-MSH containing chelators for 111In, 67/68Ga, 64Cu, 90Y, 212Pb, 99mTc, 188Re were synthesized and examined with experimental animals and in a few clinical studies. Linear Ac-Nle-Asp-His-D-Phe-Arg-Trp-Gly-Lys-NH2 (NAP-amide) and Re-cyclized Cys- Cys-Glu-His-D-Phe-Arg-Trp-Cys-Arg-Pro-Val-NH2 (Re[Arg11]CCMSH) containing different chelators at the N- or C-terminus served as lead compounds for peptide drugs with further optimized characteristics. Alternatively, melanoma may be targeted with radiopeptides that bind to melanin granules occurring extracellularly in these tumors. Photosensitizer targeting: A more recent approach is the application of photosensitizers attached to the MSH molecule for targeted photodynamic therapy using LED or coherent laser light that specifically activates the photosensitizer. Experimental studies have demonstrated the feasibility of this approach as a more gentle and convenient alternative compared to radionuclides.

    Organochlorine exposure is an important cause of cutaneous and systemic toxicity. Exposure has been associated with industrial accidents, intentional poisoning, and the use of defoliants, such as Agent Orange in the Vietnam War. Although long-term health effects are systematically reviewed by the Institute of Medicine, skin diseases are not comprehensively assessed. This represents an important practice gap as patients can present with cutaneous findings. This article provides a systematic review of the cutaneous manifestations of known mass organochlorine exposures in military and industrial settings with the goal of providing clinically useful recommendations for dermatologists seeing patients inquiring about organochlorine effects. Patients with a new diagnosis of chloracne, porphyria cutanea tarda, cutaneous lymphomas (non-Hodgkin lymphoma), and soft-tissue sarcomas including dermatofibrosarcoma protuberans and leiomyosarcomas should be screened for a history of Vietnam service or industrial exposure. Inconclusive evidence exists for an increased risk of other skin diseases in Vietnam veterans exposed to Agent Orange including benign fatty tumors, melanomas, nonmelanoma skin cancers, milia, eczema, dyschromias, disturbance of skin sensation, and rashes not otherwise specified. Affected veterans should be informed of the uncertain data in those cases. Referral to Department of Veterans Affairs for disability assessment is indicated for conditions with established associations. Copyright © 2015 American Academy of Dermatology, Inc.

    Sixteen cats with allergic dermatitis and six control cats with no skin disease were examined. Lymphoid and histiocytic cells in skin sections were examined immunohistochemically and mast cells were identified by toluidine blue staining. The 16 allergic cats showed one or more of several features (alopecia, eosinophilic plaques or granulomas, papulocrusting lesions), and histopathological findings were diverse. In control cats there were no cells that expressed IgM or MAC387, a few that were immunolabelled for IgG, IgA or CD3, and moderate numbers of mast cells. In allergic cats, positively labelled inflammatory cells were generally more numerous in lesional than in non-lesional skin sections, and were particularly associated with the superficial dermis and perifollicular areas. There were low numbers of plasma cells expressing cytoplasmic immunoglobulin; moderate numbers of MHC II-, MAC387- and CD3-positive cells; and moderate to numerous mast cells. MHC class II expression was associated with inflammatory cells morphologically consistent with dermal dendritic cells and macrophages, and epidermal Langerhans cells. Dendritic cells expressing MHC class II were usually associated with an infiltrate of CD3 lymphocytes, suggesting that these cells participate in maintenance of the local immune response by presenting antigen to T lymphocytes. These findings confirm that feline allergic skin disease is characterized by infiltration of activated antigen-presenting cells and T lymphocytes in addition to increased numbers of dermal mast cells. This pattern mimics the dermal inflammation that occurs in the chronic phase of both canine and human atopic dermatitis.

    Full Text Available Mesenchymal stem cell (MSC-based therapy involving both autologous and allogeneic MSCs shows great promise in treating several conditions. MSCs promote wound healing, and can differentiate into multiple cell lineages, including keratinocytes. Therefore, MSCs can be used for the treatment of congenital or acquired skin defects. Because of their immunomodulatory properties, MSCs may be useful for the treatment of inflammatory and autoimmune skin diseases. In particular, MSCs might be effective for the treatment of large vitiligo lesions as immunosuppressant or cultured grafts. MSCs can also be a novel cell source for regenerating hair in the treatment of scarring alopecia and androgenic alopecia. MSCs might also be an effective treatment for alopecia areata, which is associated with autoimmunity. Stem cell therapies with topical administration of MSCs and bone marrow transplantation were shown to alleviate recessive dystrophic epidermolysis bullosa in both animal models and human subjects. In addition to cell transplantation, the mobilization of endogenous MSCs has been attempted for skin regeneration. Overall, this review highlights the great potential of MSCs for the treatment of skin diseases in the near future.

    To find out views and practice of dermatologists regarding prevention of preventable skin diseases. Study Design: Cross-sectional study. Place and Duration of Study: The study was set up in Apr-May 2010 at PAF Hospital Faisal, Karachi, Pakistan. Material and Methods: A close-ended questionnaire was sent to 100 dermatologists through resource persons at different places throughout the country. It included basic information about them, their views and practice regarding prevention of these diseases. Data was managed and analyzed using SPSS-17. Results: Fifty dermatologists thought that frequency of preventable skin diseases in their clinical practice is 26-50%. Fifty-six observed educated community as the most important link for prevention, 46 held governments responsible and 42 consider busy schedule as barrier to educate community. Thirty dermatologists delivered talk to general public, 11 at schools, colleges and factories, 07 appeared on mass media and 08 prepared leaflets, pamphlets and brochures regarding preventive aspects of skin diseases at least once during last one year. Conclusion: Dermatologists in Pakistan are aware of magnitude of the problem and understand importance of public education; however only a few dermatologists have endeavored to take up this task.

  10. Role of the vitamin D3 pathway in healthy and diseased skin--facts, contradictions and hypotheses.

    Irradiation of human keratinocytes with UVB (280-320 nm) in vitro and in vivo activates the metabolism of 7-dehydrocholesterol to hormonally active calcitriol. The production of calcitriol in the skin strongly depends on the photosynthesis of vitamin D(3) which is biologically inactive in the first instance. Vitamin D(3) serves as the starting substrate for two subsequent enzymatic hydroxylation steps in epidermal keratinocytes. Both the amount of vitamin D(3) and the activity of anabolic and catabolic vitamin D hydroxylases determine the cutaneous level of calcitriol. The hormonally active metabolite of vitamin D(3) regulates a huge number of genes in keratinocytes, and thus acts in an autocrine and/or paracrine manner. This local pathway of vitamin D(3) is unique, but its relevance for healthy and diseased skin is widely unknown, yet. Experimental findings implicate several questions: (1) Is UVB-induced formation of calcitriol involved in regulation of growth and differentaition of epidermal cells as well as immunological and skin protective processes? (2) What endogenous and exogenous factors including drugs affect the cutaneous vitamin D(3) pathway? From a therapeutical point of view, it has been known for a long time that topical application of calcitriol and its analogs can improve hyperproliferative skin diseases like psoriasis. In spite of many encouraging studies in recent years, the fields of the routinely therapeutical application of calcitriol or vitamin D analogs in dermatology (e.g. treatment of immunological, inflammatory, malignancies and infectious skin diseases) have not been intensified. Why is that?

    Full Text Available The Southwest coastal plain of Taiwan is an endemic area of arsenic contamination. Residents who lived there before the 1970s and who used raw groundwater for drinking have a higher risk of arsenic poisoning. In 1968, Tseng et al. described Blackfoot disease as a peripheral vascular disease caused by chronic exposure to arsenic, thereby introducing the concept of arsenic-induced systemic illness in Taiwan. Multiple Bowen's disease (BD is one of the characteristic consequences of chronic arsenic poisoning and it usually presents as cutaneous carcinoma in situ. Multiple BD can also be associated with squamous cell carcinoma and basal cell carcinoma of the skin, as well as lung, liver, gastrointestinal, and bladder cancers. We encountered a 79-year-old male from Yun-Lin, a county in Southwest Taiwan, who presented with a progressing tumor in his right anterior chest wall. In addition, numerous keratoses and scaly skin lesions were noted on his trunk and extremities, some of which were combined with erosions. The patient was diagnosed with chronic arsenic poisoning with multiple BD and the huge tumor was confirmed as an epithelioid malignant peripheral nerve sheath tumor.

    Occupational contact dermatitis (OCD) is a common occupational disease that impacts a variety of worker groups. Skin protection and disease prevention training programs have shown promise for improving prevention practices and reducing the incidence of OCD. This review details the features of training programs for primary prevention of OCD and identifies gaps in the literature. Twelve studies were identified for in-depth review: many studies included wet workers employed in health care, hairdressing, cleaning, and food preparation; 1 program featured manufacturing workers. Few programs provided content on allergic contact dermatitis, and only 1 was evaluated for long-term effectiveness. Effective programs were similar in content, delivery method, and timing and were characterized by industry specificity, multimodal learning, participatory elements, skin care resource provision, repeated sessions, and management engagement. Long-term effectiveness, generalizability beyond OCD, workplace health and safety culture impact, and translation of programs in the North American context represent areas for future research.

    Decorative tattooing as a body art form underwent an exponential increase during the last two decades, particularly among teenagers and young adults. Consequently, the number of reported adverse reactions after tattooing has increased. The most frequent reported skin reactions to tattoo include infectious (bacterial, viral, fungal) or inflammatory (allergic contact dermatitis and granulomatous reaction) diseases. Moreover, tattoos can also induce the development of typical skin lesions of pre-existing dermatoses, a phenomenon known as isomorphism reactive or Koëbner phenomenon, which commonly occurs in patients with psoriasis, vitiligo, or lichen planus. A retrospective study analyzing records data of patients attending the Department of Dermatology, University of Naples "Federico II" during 2011-2015 was performed. All cases of tattoorelated or closely located dermatitis were selected. We observed 19 patients (mean age: 26.4 year-old) showing cutaneous conditions related to the practice of tattooing. Allergic contact dermatitis was reported as the most common cutaneous disease linked to tattooing (31.6%), followed by granulomatous reactions (26.3%). These data are consistent with those already reported in literature. Our results highlight the need to develop detailed regulations regarding tattoos practice, used materials, as well as execution procedures in order to limit the outbreak of tattooing related skin diseases.

    For many years radionuclide studies have afforded an invaluable aid to clinicians for the detection and management of malignant tumors of the liver. Alternative methods for producing images of the liver are now available to the radiologist, and each technique has exhibited a variety of useful and limiting features. In an effort to clarify and guide choices about applications of all radiological techniques, our department recently developed a monograph describing algorithms for optimal use of all imaging modalities by referring physicians. The approach to detection of hepatic metastases illustrates in a correlative way applications of radioisotope imaging in such patients. As presented, the algorithm is neither identical to nor unlike those recommended or published elsewhere. This chapter reviews the major applications of radionuclide imaging for metastatic cancer of liver with close attention to the clinician's point of view

    2014-04-01

    Full Text Available Introduction: Human genes responsible for human antigen presentation and transplant rejection functions are located on the short arm of Chromosome 6 and are called the Major Histocompatibility Complex (MHC. Moreover, the primary physiologic function of MHC molecules is to present peptides to T lymphocytes. MHC molecules are integral components of the ligands that most T cells recognize, since the T cell receptor (TCR has specificity for complexes of foreign antigenic peptides, as well as self-MHC molecules. Aim: Our investigation attempts to investigate the presence of HLA-DPDQDR within lesional skin biopsies from patients affected by autoimmune skin blistering diseases (ABDs. Materials and Methods: We utilized immunohistochemistry (IHC to evaluate the presence of HLA-DPDQDR in lesional skin biopsies of patients affected by ABDs. We tested 30 patients with endemic pemphigus foliaceus (EPF, 15 controls from the EPF endemic area, and 15 biopsies from healthy controls from the USA. We also tested archival biopsies from patients with selected ABDs, including 30 patients with bullous pemphigoid (BP, 20 with pemphigus vulgaris (PV, 8 with pemphigus foliaceus (PF, 14 with dermatitis herpetiformis (DH and 2 with epidermolysis bullosa acquisita (EBA. Results: Most ABD biopsies stained positive for HLA-DPDQDR in the lesional blisters and/or inflamed neurovascular plexus in the superficial dermis, and also at mesenchymal-endothelial like-cell junctions in the dermis. In BP, EBA and EPF, the HLA-DPDQDR staining was also seen in the dermal eccrine sweat gland coils and and ducts. Conclusion: Here, we document that HLA-DPDQDR is expressed in several anatomic areas of lesional skin in patients with ABDs. Notably, HLA-DPDQDR positivity was also consistently present in areas of the classic immune response in pemphigus epidermal keratinocytic intercellular junctions, and at basement membrane sites in bullous pemphigoid and other subepidermal blistering diseases.

    A number of benign and malignant diseases may cause pleural abnormalities. Since the resolution of computed tomography (CT) has been improved, the detailed anatomy of pleura can now be well delineated in various pleural diseases. We reviewed retrospectively the CT findings of 60 patients with pathologically proved pleural diseases in order to find out the differential points between benign and malignant diseases. Thirty-six patients had malignant diseases (20 adenocarcinoma, 8 squamous cell carcinoma, 4 small cell carcinoma, 2 lung metastasis, 1 large cell carcinoma, 1 small and large cell carcinoma), and 24 patients had benign diseases (16 tuberculosis including empyema, 3 bacterial empyema, 3 pneumonia, 1 lung abscess, 1 lung contusion). The CT features that suggested malignant pleural diseases were high-grade mediastinal involvement (57.9%, {rho} < 0.1), thick and irregular thickening with nodularity and mass formations (38.5%, {rho} < 0.1), Circumferential pleural thickening 132.1%, {rho} < 0.01), and aggressive pleural effusion 122.2%, {rho} < 0.05). Benign pleural lesions were typically represented by pleural calcification (50%) and extrapleural fat accumulation (45.8%)

    2015-07-01

    Data emerging from the International Collaborative Gaucher Group (ICGG) Gaucher Registry together with other contemporary clinical surveys have revealed a close association between Gaucher disease and non-Hodgkin's B-cell lymphoma and myeloma and Gaucher disease and Parkinson's disease. Several possible explanations for increased B-cell proliferation and neoplasia in Gaucher disease have been proposed, including the possible influence of sphingosine (derived from the extra lysosomal metabolism of glucosylceramide), gene modifiers, splenectomy and immune system deregulation induced by cytokines, chemokines, and hydrolases released from Gaucher cells. Parkinson's disease is frequently seen in the otherwise-healthy relatives of Gaucher disease patients leading to the finding that GBA mutations represent a genetic risk factor for Parkinson's disease. The mechanism of the association between GBA mutations and Parkinson's disease has yet to be elucidated but the pathogenesis appears distinct from that of Gaucher disease. Several pathogenic pathways have been proposed including lysosomal and/or mitochondrial dysfunction. The effect of Gaucher disease specific therapies on the incidence of cancer or Parkinson's disease are not clear and will likely be evaluated in future ICGG Gaucher Registry studies. © 2015 Wiley Periodicals, Inc.

    Stress is an important factor in the onset, exacerbation and reoccurrence of many skin diseases. Little is known about psychological risk factors that affect the association between stress and dermatological conditions. One relevant factor that may modulate this link is anxiety sensitivity (AS) social concerns - the propensity to respond fearfully to anxiety-related sensations (e.g. sweating, flushing) owing to perceived social consequences (e.g. rejection or humiliation). To gain insight into psychological factors affecting skin disease, we examined the moderating role of AS social concerns in the relationship between stress and skin disease quality of life (QoL). Participants [n = 237 (161 female), mean ± SD age 34·18 ± 9·57 years] with active skin disease symptoms were recruited online and completed questionnaires assessing stress, AS social concerns, skin disease QoL and global skin disease symptom severity. AS social concerns moderated the association between stress and skin-related emotional and social functioning in adults with skin disease. Stress was a significant predictor of the impairment associated with skin disease. Stress was linked to skin disease-related emotional and functional impairment associated with skin disease among individuals with high AS social concerns. These results highlight the potential for AS reduction interventions to break the vicious cycle of stress and skin disease symptoms and to improve psychosocial well-being in dermatology patients. © 2017 British Association of Dermatologists.

    Allogeneic bone marrow transplantation (BMT) represents an important therapeutic tool for treatment of otherwise incurable malignant and non-malignant diseases. Until recently, myeloablative regimens were considered mandatory for eradication of all undesirable host-derived hematopoietic elements. Our preclinical and ongoing clinical studies indicated that much more effective eradication of host immunohematopoietic system cells could be achieved by adoptive allogeneic cell therapy with donor lymphocyte infusion (DLI) following BMT. Thus, eradication of blood cancer cells, especially in patients with CML can be frequently accomplished despite complete resistance of such tumor cells to maximally tolerated doses of chemoradiotherapy. Our cumulative experience suggested that graft versus leukemia (GVL) effects might be a useful tool for eradication of otherwise resistant tumor cells of host origin. The latter working hypothesis suggested that effective BMT procedures may be accomplished without lethal conditioning of the host, using new well tolerated non-myeloablative regimen, thus possibly minimizing immediate and late side effects related to myeloablative procedures considered until recently mandatory for conditioning of BMT recipients. Recent clinical data that will be presented suggests that safe non-myeloablative stem cell transplantation (NST), with no major toxicity can replace the conventional BMT. Thus, NST may provide an option for cure for a large spectrum of clinical indications in children and elderly individuals without lower or upper age limit, while minimizing procedure-related toxicity and mortality.

    Full Text Available Abstract Background Post-transplant lymphoproliferative disorder (PTLD is a complication of solid organ and allogeneic hematopoietic stem cell transplantation (HSCT; following autologous HSCT only rare cases of PTLD have been reported. Here, a case of Hodgkin's disease (HD, as unusual presentation of PTLD after autologous HSCT for malignant glioma is described. Case presentation 60-years old man affected by cerebral anaplastic astrocytoma underwent subtotal neurosurgical excision and subsequent high-dose chemotherapy followed by autologous HSCT. During the post HSCT course, cranial irradiation and corticosteroids were administered as completion of therapeutic program. At day +105 after HSCT, the patient developed HD, nodular sclerosis type, with polymorphic HD-like skin infiltration. Conclusion The clinical and pathological findings were consistent with the diagnosis of PTLD.

    This study characterizes the expression of tau (p-tau) and α-synuclein (α-syn) by immunohistochemistry in the skin of three different populations: healthy control (HC), Parkinson disease (PD), and progressive supranuclear paralysis (PSP) subjects, with the purpose of finding a biomarker that could differentiate between subjects with PD and PSP. We evaluated the presence of p-tau and α-syn in a pilot study in the skin of three distinct groups of patients: 17 healthy subjects, 17 patients with PD, and 10 patients with PSP. Four millimeters punch biopsies were obtained from the occipital area and analyzed by immunohistochemistry using antibodies against α-syn and phosphorylated species of tau. PHF (paired helical filaments) antibody identifies p-tau in both normal and pathological conditions and AT8 recognizes p-tau characteristic of pathological conditions. Differences between the three groups were assessed by quantification of immunopositive areas in the epidermis. The immunopositivity pattern of p-tau and α-syn was significantly different among the three groups. Healthy subjects showed minimal staining using AT8 and α-syn. The PD group showed significantly higher α-syn and AT8 immunopositivity, while the PSP group only expressed higher AT8 immunopositivity than HCs. These data suggest that the skin reflects brain pathology. Therefore, immunohistochemical analysis of p-tau and α-syn in the skin can be useful for further characterization of PD and PSP.

    Occupational contact dermatitis (OCD) is a common occupational disease. Evidence suggests that education and training are effective prevention strategies. In spite of these known prevention strategies, workers continue to develop OCD. Little is reported regarding the actual training experience of workers. To examine the training experience of workers with contact dermatitis to identify areas for improvement. Participants were workers being assessed for contact dermatitis in an occupational health clinic. The anonymous survey collected demographics, workplace characteristics, and education and prevention practices. Approximately 80% reported general occupational health and safety training; however, only 49% reported skin-specific training (SST). For workers reporting SST, most received information regarding exposure avoidance, hand washing, and glove use. This content was reported as helpful by at least 50%. Workers who did not receive SST indicated the most important content would be warning signs of skin problems, how to avoid exposure and skin care while using gloves. While the study was anonymous and used self-reported of training experience, the study suggests there are gaps in skin protection training. Addressing these gaps may lead to improved prevention and reduction in OCD. © The Author(s) 2017. Published by Oxford University Press on behalf of the British Occupational Hygiene Society.

    One of the most specific and critical regulators of angiogenesis is vascular endothelial growth factor (VEGF), which regulates endothelial proliferation, permeability, and survival. Vascular endothelial growth factor is an angiogenic mediator in tumors and has been implicated in the pathogenesis and progression of cancer. Adipose tissue is a major endocrine and it secretes hormones termed adipokines. These factors are derived from adipocytes and include proteins and metabolites such as adiponectin. Recently, adiponectin was also shown to modulate angiogenesis. This study was designed to determine the serum VEGF and adiponectin levels in patients with benign and malignant gynecological diseases and if there was a correlation between serum VEGF and adiponectin. Serum samples, collected fasting before surgery or intervention, were available for total of 114 female patients recorded between October 2006 and December 2008. Diagnosis of benign and malignant gynaecological diseases was established by biopsy. Serum levels VEGF and adiponectin were using commercially available enzyme linked immunosorbent assay (R&D Systems Inc, Minneapolis, MN), respectively. Statistical analysis was performed by using the SPSS 9.0 software package (SPSS, Inc, Chicago, IL). The correlation between serum VEGF and serum Adiponectin was calculated using the Pearson correlation coefficient. P values of benign and malignant gynecological diseases of the patient. Only for serum VEGF levels was a significant difference observed (P = 0.004) between patients with benign and malignant gynecological diseases. A significantly inverse correlation between serum VEGF and adiponectin levels among patients with benign and malignant gynecological diseases was found. Adiponectin level is not correlated with body mass index. This is one of the first report on adiponectin in benign and malignant gynecological diseases. Future studies are needed to address the clinical potential role of adiponectin in cancer.

    Squamous cell carcinomas are the most frequent malignancies of the inner nose, followed by adenocarcinomas, adenoid cystic carcinomas, and other malignant neoplasms. Carcinomas of the nose can be recognized as occupational diseases if there has been a professional exposition to ionizing rays, certain arsenic compounds, hexavalent chrome compounds, nickel, oak or beech wood dust. The sources of danger relevant in industrial medicine are indicated. At present, adenocarcinomas induced by dust of wood are of special significance: 16 out of 22 carcinomas of the nose recognized as occupational diseases between 1978 and 1986 are due to oak and beech wood dust.

    Etiological relationship between previous radiation exposure and malignant diseases concerned could be estimated from NIH Epidemiological Tables expressed as Probability of Causation (PC). But the limit of PC in the compensation of radiation induced malignant diseases has not been decided definitely. In this paper PC calculations were made for populations of occupational exposure with typical distribution of individual doses and levels of exposure. The results show that it is feasible to choice PC ≥ 50% as a limit of compensation for leukemia and radon induced lung cancer. Some lenient limits may be taken for other radiation related solid carcinomas

    Full text: Introduction: Computed tomography urography is among the fastest growing imaging directions, indications of which continue to change. Radiation dose is one of its main disadvantages. There are a number of literary publications regarding how to reduce radiation dose: by voltage, by mA or by reducing the number of phases. What you will learn: We present the initial experience in the diagnosis of non-malignant kidney disease with three low-dose study protocol: a standard low dose, low dose and low dose introduced by us. Our research is based on three groups of patients. The first of 36 men and 22 women viewed with repetitive low-dose protocol: 120 kV / 219 effective milliampere. The second and third group of 16 men and 9 women, respectively: 100/ 163 and 80/115 . Discussion: There have been a number of studies to reduce the radiation dose that is considered one of the main disadvantages of computed tomography urography. Reducing mA (≤ 30 mAs), leads to the radiation dose similar to that of an overview abdominal radiography. Reducing of 140 kV to 120, reducing the dosage of the skin by about 33 % and decreasing it to 80 kilovolts, the result is about 70 %. Another technology to reduce radiation exposure is by reducing the number of phases of the study, but studies have shown that the removal of the native phase is not desirable. Conclusion: We believe that computed tomography urography is a detailed study that should be applied in certain clinical indications. Its major disadvantage is the radiation dose. Images obtained with low-dose protocols are newly comparable image quality to the standard, but with much lower radiation exposure

    Skin tumours of the anterior auricular concha are not uncommon. Wider excision and immediate reconstruction are required to reduce the risks of recurrence of the disease, cartilage infection and external ear distortion. Many surgical methods have been described for reconstruction of conchal defects. Post-auricular island flaps, such as the revolving-door (RD) flap, and full-thickness skin grafts (FTSGs) are the most-performed procedures. Although the RD flap has been fully described, it is not widely accepted and many surgeons, in their daily practice, prefer to use FTSG. It is a common experience that FTSGs are more subjected to centripetal contraction, decreasing the structural firmness of the conchal cavity and affecting functional and aesthetic outcomes. Furthermore, FTSGs are more prone to delay in wound healing due to the difficult access to this region that hinders adequate tie-over dressings. Between March 2003 and January 2007, 40 patients affected by T1 and T2 non-melanotic skin cancer and T1 melanoma of the anterior conchal surface of the external ear were included in a prospective study and randomly assigned to the RD reconstructed group or to the FTSG reconstructed group to investigate, compare and define advantages and disadvantages of both the techniques. Visual Analogue Scale (VAS) was used to evaluate the overall outcome and the colour and texture match. No flap or skin graft total loss was observed. Six patients (30%) showed partial failure of FTSG. The RD group demonstrated excellent cosmetic outcome, ideal colour match, adequate structure of external ear, projection and shape. Wilcoxon matched-pairs rank-sum test demonstrated statistically significant higher scores for the RD group compared to the FTSG group (p<0.0001). The RD harvesting technique is easy and quicker than the FTSG technique. RD flap should be considered as the first choice for reconstruction of anterior auricular conchal defects following wider excision of skin tumours

    Lung diseases are described by a wide variety of developmental mechanisms and clinical manifestations. Accurate classification and diagnosis of lung diseases are the bases for development of effective treatments. While extensive studies are conducted toward characterization of various lung diseases at molecular level, no systematic approach has been developed so far. Here we have applied a methodology for pathway-centered mining of high throughput gene expression data to describe a wide range of lung diseases in the light of shared and specific pathway activity profiles. We have applied an algorithm combining a Pathway Signal Flow (PSF) algorithm for estimation of pathway activity deregulation states in lung diseases and malignancies, and a Self Organizing Maps algorithm for classification and clustering of the pathway activity profiles. The analysis results allowed clearly distinguish between cancer and non-cancer lung diseases. Lung cancers were characterized by pathways implicated in cell proliferation, metabolism, while non-malignant lung diseases were characterized by deregulations in pathways involved in immune/inflammatory response and fibrotic tissue remodeling. In contrast to lung malignancies, chronic lung diseases had relatively heterogeneous pathway deregulation profiles. We identified three groups of interstitial lung diseases and showed that the development of characteristic pathological processes, such as fibrosis, can be initiated by deregulations in different signaling pathways. In conclusion, this paper describes the pathobiology of lung diseases from systems viewpoint using pathway centered high-dimensional data mining approach. Our results contribute largely to current understanding of pathological events in lung cancers and non-malignant lung diseases. Moreover, this paper provides new insight into molecular mechanisms of a number of interstitial lung diseases that have been studied to a lesser extent. PMID:27200087

    There is a long history recording the association of x radiation and the subsequent development of malignant tumors. For systemically administered isotopes this came into prominence when Martland discovered the association between cancer, particularly of the bone, and ingestion of radioactive isotopes by radium dial painters. This association was amplified by the development of cancer in patients given thorotrast as a contrast medium for diagnostic radiologic examination. Acute leukemia was reported 30 years ago in patients with polycythemia vera treated with 32 P. Acute leukemia also occurs in patients with polycythemia vera treated only with phlebotomy or drugs. A controlled study is now underway to provide a more definite answer to question what is the incidence of acute leukemia in patients with polycythemia vera treated by phlebotomy alone, chlorambucil, or 32 P. 131 I for the treatment of hyperthyroidism probably does not induce cancer, but in the doses used for thyroid cancer there was an increased incidence of neoplasms (12/200 in one study). This was higher than the expected incidence of neoplasms. The doses of radioactive isotopes used currently for diagnostic purposes have not induced cancer, but it is difficult and probably impossible to verify this with absolute certainty

    Full Text Available Abstract Background Malignant peripheral nerve sheath tumours (MPNST are rare tumours known to occur at high frequency in neurofibromatosis 1 (NF1, but may also occur in other cancer prone syndromes. Methods The North West Regional Genetic Register covers a population of 4.1 million and was interrogated for incidence of MPNST in 12 cancer prone syndromes. Age, incidence and survival curves were generated for NF1. Results Fifty two of 1254 NF1 patients developed MPNST, with MPNST also occurring in 2/181 cases of schwannomatosis and 2/895 NF2 patients. Three cases were also noted in TP53 mutation carriers. However, there were no cases amongst 5727BRCA1/2 carriers and first degree relatives, 2029 members from Lynch syndrome families, nor amongst 447 Familial Adenomatous Polyposis, 202 Gorlin syndrome, nor 87 vHL cases. Conclusion MPNST is associated with schwannomatosis and TP53 mutations and is confirmed at high frequency in NF1. It appears to be only increased in NF2 amongst those that have been irradiated. The lifetime risk of MPNST in NF1 is between 9–13%.

    Tobacco smoking in any form is a major risk factor for coronary artery disease (CAD), hypertension (HTN), chronic obstructive pulmonary disease (COPD), oral, nasopharyngeal, bronchial and other visceral malignancies. Cessation of smoking exerts considerable beneficial effect on development, recurrence and prognosis of these diseases. Present communication is based on the study of nine cases who had concurrent CAD, HTN, COPD and mitotic and/or pre malignant lesions due to unabated smoking. The youngest patient was a 35-year-old male having a smoking index of 300, presenting with acute coronary syndrome, COPD, HTN and buccal leukoplakia. Associated genitourinary malignancies in two cases and osteosarcoma in one case was an unusual presentation. These cases highlight the prognosis and public health implications of continuous smoking.

    2008-07-01

    Full Text Available Abstract Introduction Pulmonary talc granulomatosis is a rare disorder characterized by the development of foreign body granuloma secondary to talc exposure. Previous case reports have documented the illness in current intravenous drug users who inject medications intended for oral use. We present a rare case of the disease in a patient with a distant history of heroin abuse who presented initially with history and imaging findings highly suggestive of malignancy. Case presentation A 53-year-old man reported a 4-month history of increasing dyspnea and weight loss. He had a long history of smoking and admission chest X-ray revealed a density in the right hemithorax. Computed tomography confirmed a probable mass with further speculated opacities in both lung fields suspicious for malignant spread. Biopsies obtained using endobronchial ultrasound-guided aspiration returned negative for malignancy and showed bronchial epithelial cells with foreign body giant cell reaction and polarizable birefringent talc crystals. Conclusion This case demonstrates a rare presentation of talc granulomatosis three decades after the last likely exposure. The history and imaging findings in a chronic smoker were initially strongly suggestive of malignant disease, and we recommend that talc-induced lung disease is considered in any patient with multiple scattered pulmonary lesions and a history of intravenous drug use. Confirmation of the disease by biopsy is essential, but unfortunately there are few successful proven management options for patients with worsening disease.

    Thymomas are rare malignant epithelial growths, constituting 20% of mediastinal tumours. Resection followed by irradiation may be employed in all thymomas except for stage 1 thymomas. Mediastinal irradiation is associated with coronary artery disease. The mean duration of presentation of post-irradiation coronary artery disease is 16 years (range 3-29 years). In our patient coronary artery disease was found only a year post irradiation. A 55 year old male who presented with complaints of dyspnoea, retrosternal chest pain and heaviness since one year underwent resection for malignant thymoma followed by radiotherapy. He presented with coronary artery disease a year after undergoing mediastinal irradiation. On follow-up, patient was treated successfully by coronary artery bypass graft. This case is an unusual occurrence and suggests that mediastinal irradiation may result in significant coronary artery disease as early as within one year. (author)

    Umbilical cord blood (UCB) from an human leucocyte antigen (HLA)-identical sibling can be used for transplantation of patients with malignant and non-malignant diseases. However, the low cellular content of most UCB units represents a limitation to this approach. An option to increase cell dose is to harvest bone marrow (BM) cells from the same donor and infuse them along with the UCB. We studied 156 children who received such a combined graft between 1992 and 2011. Median age was 7 years and 78% of patients (n = 122) were transplanted for non-malignant diseases, mainly haemoglobinopathies. Acute leukaemia (n = 26) was the most frequent malignant diagnosis. Most patients (91%) received myeloablative conditioning. Median donor age was 1·7 years, median infused nucleated cell dose was 24·4 × 10(7) /kg and median follow-up was 41 months. Sixty-days neutrophil recovery occurred in 96% of patients at a median of 17 d. The probabilities of grade-II-IV acute and chronic graft-versus-host disease (GVHD) were 19% and 10%, respectively. Four-year overall survival was 90% (68% malignant; 97% non-malignant diseases) with 3% probability of death. In conclusion, combined UCB and BM transplantation from an HLA-identical sibling donor is an effective treatment for children with malignant and non-malignant disorders with high overall survival and low incidence of GVHD. © 2014 John Wiley & Sons Ltd.

    Previous studies have not showed consistent results for the level of expression of sodium/iodide symporter (NIS) in thyroid diseases, especially malignant tumor. We undertook this study to evaluate the distribution of NIS expression in malignant thyroid diseases and compare with that in benign thyoid disease. Total patients were 119 cases (Men 15, 48±13 yrs). Total number of samples were 205 pieces. In malignant thyroid disease, there were 153 samples: 90 in papillary carcinoma, 4 in follicular carcinoma, 2 in medullary carcinoma and 57 in metastatic lymph node. In benign thyroid disease, there were 52 samples: 36 in goiter/cyst, 11 in thyroiditis and 5 in follicular adenoma. Using immunohistochemical methods, we probed 205 samples with monoclonal anti-NIS Ab. Grading of staining was scored as 0 (negative or absent), 1 (weakly positive), 2 (moderately positive) or 3 (strongly positive). Expression rate (ER) of NIS positivity in individual disease entity was expressed as percentage of total number divided by number in 2 plus 3 grade. ERs of malignant thyroid diseases were 63% in papillary carcinoma, 81% in metastatic lymph node, 71% in follicular carcinoma and 100% in medullary carcinoma. ERs of benign thyroid disease were 53% in goiter/cyst, 64% in thyroiditis and 40% in follicular adenoma. ER of benign thyroid deceases was higher than benign thyroid diseases (71% vs 54%). Grading of NIS expression in papillary carcinoma or goiter/cyst was heterogeneously distributed in considerable cases. Normal tissue also showed heterogeneous distribution or NIS expression, which was not correlated with that of primary lesion. In papillary thyroid carcinoma, distribution of NIS expression was heterogeneous and increased, and not different compared with that of benign thyroid disease

    Full Text Available We report the case of a 72-year-old woman with malignant melanoma and multiple metastases; the largest tumor was in the ileum. The patient experienced general fatigue and bloody feces for 1 month before consulting a nearby clinic. Blood tests revealed anemia, and fecal occult blood was positive, but no abnormalities were detected using gastrointestinal endoscopy and colonoscopy or the skin of the entire body. Computed tomography images of the chest, abdomen, and pelvic region, and positron emission tomography–computed tomography images of the entire body revealed multiple nodules in the ileum, left mammary gland, left thyroid, right inguinal lymph node, and on the fascia of the right thoracic area and right buttocks. The tumor in the left mammary gland was excised and immunohistochemical analysis revealed that the excised tissue was positive for HMB45, melan-A, and MITF, but negative for S-100 protein. Diagnosed with melanoma with multiple metastases, the patient underwent four cycles of dacarbazine, nimustine hydrochloride, and vincristine (DAV plus interferon beta chemotherapy and one cycle of dacarbazine, nimustine hydrochloride, cisplatin, and tamoxifen (DAC-Tam chemotherapy. Two series of embolizations of the artery feeding the ileum tumors, as well as a series of plasma and red blood cell transfusions, were performed for ileum tumor hemorrhage. The patient was hospitalized eight times, for a total of 204 days during the 1-year survival period before her death from respiratory failure.

    In a patient receiving balneotherapy, iching is reduced into a throbbing pain by bathing in very hot water or in a tonic spring. Dermatitis caused by bathing in an acid spring is a typical case. A scab may be built after bathing in an acid sulfur spring, but it protects the skin from scratching that is an undesirable conditioned reflex. In the treatment of skin diseases, although steps are taken in many cases to control inflammation, yet it is accepted that damaged skin does not heal without inflammation. In balneotherapy, inflammation suppressing actions are seldom taken, but inflammation is positively made use of in some cases and is caused to be aggravated. In a patient being treated by bathing in an acid sulfur spring, inflammation is enhanced and the patient appears to be taking a turn for the worse. This is known as `extracting of poison` in the hot spring cure terminology. With this apparent worsening, anthemata are in most cases cured more effectively than without. Also, inflammation is an indispensable reaction of countering microbial infection

    In this paper, the relation between psychological factors and psychiatric disorders in patients with skin diseases is discussed. On the one hand psychological factors (stress, negative emotions) can influence the generation and aggravation of skin disorders (urticaria, atopic dermatitis, vitiligo), on the other hand psychological disorders can result in some skin diseases (psoriasis, atopic dermatitis). In the majority of cases the quality of life is poorly estimated by patients with skin problems. Psychodermatology is divided into three categories according to the relationship between skin diseases and mental disorders: 1) psychophysiologic disorders caused by skin diseases triggering different emotional states (stress), but not directly combined with mental disorders (psoriasis, eczema); 2) primary psychiatric disorders responsible for self-induced skin disorders (trichotillomania); and 3) secondary psychiatric disorders caused by disfiguring skin (ichthyosis, acne conglobata, vitiligo), which can lead to states of fear, depression or suicidal thoughts.

    Objective: To differentiate malignant and degenerative benign bone disease using 99m Tc- citrate scintigraphy. Methods: Thirty-nine patients (92 lesions) with confirmed malignant bone disease or degenerative benign bone disease were studied, for which the results of 99m Te-methylene diphosphonate( 99m Tc- MDP) scintigraphy were positive. 99m Tc-citrate scintigraphy was performed within a time interval of 2-7 days after 99m Tc-MDP scintigraphy. Visual analysis and semiquantitative analysis were applied. Each lesion was scored as malignant or benign, which was independently verified, using conventional techniques (histopathology, X-ray, CT, MRI and clinical follow up). Results: In visual analysis of 99m Tc-citrate imaging, most malignant lesions (35/48, 72.92%) clearly showed high radioactivity accumulation, while most benign lesions (39/44, 88.64%) had not obviously visible uptake of 99m Tc-citrate. In semiquantitative analysis of 99m Tc- citrate image, malignant lesions demonstrated a higher lesion-to-background radioisotope uptake ratio (RUR) than that of benign degenerative lesions (1.47 ± 0.42 vs. 1.09 ± 0.38, t=2.887, P 99m Tc-MDP in the two groups is of the same (1.96 ± 0.25 vs. 1.87 ± 0.21, t=1.178, P>0.20). Conclusion: 99m Tc- citrate scintigraphy is a promising method to differentiate malignant from benign degenerative lesions seen as areas of increased activity on 99m Tc-MDP bone scintigraphy.

    Little research has been focused on the health status or the occupational protection awareness of sanitation workers. The policy recommendations on the occupational safety and health of sanitation workers based on the scientific research are also insufficient in developing countries like China. To study the incidence of dermatoses and the relevance with occupational exposure, protection awareness and protective measures among sanitation workers for better management and protection of the sanitation workers. 273 sanitation workers and 113 administrative staff from 11 streets of Wuhan were recruited. Dermatological problems were evaluated and recorded by physical examination. Occupational exposure, protection awareness, the use of protective equipments and personal history of skin disease were assessed by questionnaires. Compared with administrative staff, sanitation workers had much more occupational dermatological problems and had a much higher rate of harmful ultraviolet ray exposure. Young sanitation workers were more aware of occupational self-protection and a relatively higher rate of them using protective equipments compared with old ones. Exposure to multiple health hazards and the poor use of protective equipments are related to skin diseases in sanitation workers. Prejob training of self-protection and the use of protective equipments are recommended.

    Full Text Available Introduction: The pattern of skin diseases in any community is influenced by genetic constitution, climate, socioeconomic status, occupation, education, hygienic standards, customs and quality of medical care. The burden of skin disease also has an impact on the Quality of Life of adolescents. This study aims to investigate the level of awareness and assess the prevalence of different types of skin diseases among adolescents in Mauritius. Material and Methods: 500 adolescents and young adults of both sexes and aged between 11-23 years were recruited. A questionnaire was used to elicit information and to assess the knowledge status of skin diseases and to determine possible risk factors. In addition, a validated questionnaire based on Quality of Life Index was used to determine the psychosocial effect of adolescents suffering from skin diseases. Data was analysed using IBM Statistics SPSS version 20 and Microsoft Excel 2007. Results: Incidence of skin diseases was 22.9% in males and 24.7% females respectively. Acne was the most common skin problems in both gender followed by fungal infection (2.9% in males and eczema (2.4% in females. Climatic conditions (e.g summer, consumption of oily and spicy foods, sports practice and familial history were correlated positively with prevalence of skin diseases. Conclusion: Acne, eczema and fungal infection were the most common skin diseases identified. The findings also indicate that more respondents between 15-19 years old were more prone to skin diseases.

    There is a long term need for precise data on the global frequency of malignant diseases in the Socialist Republic of Serbia. The Public Health Care Establishment introduced the mechanographic data collection and registration for every patient. Using these data the authors could represent an analytical-epidemiological survey and the significance of malignant diseases in Serbia. The data on mortality from the Republic Institute of Statistics was also used. This publication presents the morbidity statistics for the topic localisations of malignant diseases, according to the sex, residence and their share in the total pathology in Serbia. The recent data on mortality due to malignant diseases are presented at the same time. The fight against malignant diseases does not include only the treatment itself but, at the same time, has to examine all the facts contributing to the development of malignant diseases such as: time, region, life conditions - habits, profession etc. From five deaths in our country, one dies due to a malignant disease. Mortality due to cancer increases by 1.8% per year, as mortality statistics show. At the same time we have an increase in the age group over 60 years. Science has not discovered the direct-actual cause of cancer but risk factors are well known, especially cancerogenous materials which contribute to the development of the disease. The significant fact is, at first glance, the heterogeneity of risk factors being in contact with the collective as well as with the individual life of all population members. These factors can be found in the environment as well as in the professional environment and are directly connected to the individual habits: smoking, alcohol, diet, hormonal life, various infections, immunological resistance of an individual, drugs, inheritance etc. The topic aims of cancer prevention are: 1) to define the dimension and significance of the problem in a defined population, 2) to conduct action with the aim to prevent

    Skin disease is an infectious disease that is common in people of all ages. Disorders of the skin often occur because there are factors, among others, are climate, environment, shelter, unhealthy living habits, allergies and others. Skin diseases in Indonesia are mostly caused by bacterial, fungal, parasitic, and allergies. The objective of the research is to diagnose skin diseases in humans by using the method of making decision tree then performing the search by forward chaining and calculating the probability value of Dempster-Shafer method. The results of research in the form of an automated system that can resemble an expert in diagnosing skin disease accurately and can help in overcoming the problem of skin diseases.

    The number of dermatologic entities that can be studied by ultrasound examination (US) of the skin is increasing. Conventional US and high frequency US (HFUS) are considered useful additional tools in improving the diagnosis and management of common benign and malignant skin tumors. US may help in positive and differential diagnosis of primary melanocytic neoplasms and of locoregional spread in melanoma patients. US preoperative evaluation of primary melanoma thickness correlates with histologically estimated melanoma thickness, and can help determine surgical margins and indications for sentinel lymph node biopsy. It is also useful during follow-up after surgical treatment for early detection of recurrence or metastases. In this case report, we present two cases of skin lesions clinically suspicious for malignancy. The first lesion was a round nodule 3 mm in diameter, resembling a blue nevus. In HFUS it was well delimited, hypoechoic, and well vascularized. The second lesion presented as an elevated, well-circumscribed nodule, 5-6 mm in diameter, inhomogeneous in color. HFUS depicted a poorly delimited, irregular, hypoechoic lesion crossing the dermoepidermal junction. At the first exam it was not vascularized, but 6 months later a number of vascular flow signals within the lesion were found. In histopathological examination the lesions were finally diagnosed as, respectively: benign cavernous hemangioma and melanoma. In both presented cases HFUS proved to be useful in a differential diagnosis of suspicious skin lesions. Noninvasive and easy to perform, HFUS is a valuable diagnostic method in dermatology.

  1. A risk prediction score for invasive mold disease in patients with hematological malignancies.

    Marta Stanzani

    Full Text Available BACKGROUND: A risk score for invasive mold disease (IMD in patients with hematological malignancies could facilitate patient screening and improve the targeted use of antifungal prophylaxis. METHODS: We retrospectively analyzed 1,709 hospital admissions of 840 patients with hematological malignancies (2005-2008 to collect data on 17 epidemiological and treatment-related risk factors for IMD. Multivariate regression was used to develop a weighted risk score based on independent risk factors associated with proven or probable IMD, which was prospectively validated during 1,746 hospital admissions of 855 patients from 2009-2012. RESULTS: Of the 17 candidate variables analyzed, 11 correlated with IMD by univariate analysis, but only 4 risk factors (neutropenia, lymphocytopenia or lymphocyte dysfunction in allogeneic hematopoietic stem cell transplant recipients, malignancy status, and prior IMD were retained in the final multivariate model, resulting in a weighted risk score 0-13. A risk score of 5% of IMD, with a negative predictive value (NPV of 0.99, (95% CI 0.98-0.99. During 2009-2012, patients with a calculated risk score at admission of 6 (0.9% vs. 10.6%, P <0.001. CONCLUSION: An objective, weighted risk score for IMD can accurately discriminate patients with hematological malignancies at low risk for developing mold disease, and could possibly facilitate "screening-out" of low risk patients less likely to benefit from intensive diagnostic monitoring or mold-directed antifungal prophylaxis.

    The purpose of this study was to assess the efficacy and problems of radiotherapy for patients aged 85 or older. Forty-five patients were assessed (oldest old group): They were 85 years of age or older and had received radiotherapy between September 2002 and September 2005. Sixty-nine patients, 75 years of age at the start of radiotherapy, were also assessed (old group). In the oldest old group, there were 21 men and 24 women, and median age was 87 years (range; 85-99). The sites of disease were: 10 in head and neck, 5 in lung, 5 in malignant lymphoma, 4 in skin, 4 in esophagus, 2 in breast, 2 in uterine cervix, 2 in rectum, 2 in soft tissue, 2 in metastatic bone tumor, 7 in others. The treatment was deemed curative in 49%, palliative in 40%, and others in 11%. Treatment fields were limited due to performance status (PS) or age in 13 patients. The rate of treatment completion was 91% (41/45). Eleven of 26 inpatients were admitted because of difficulty in hospital visit. Seventeen of 19 outpatients needed familial escort. Of patients completed radiotherapy, 47% of the patients achieved complete response (CR), 37% achieved partial response (PR), and 16% achieved no change (NC) in the group of curative radiotherapy, and 88% of the patients achieved effective response, and only 2 cases resulted in ineffective response in the group of palliative radiotherapy. While only one patient received grade 3 dermatitis and mucositis, other patients received grade 2 and below adverse events. Three patients resulted in deterioration of PS, and 2 patients deteriorated dementia. Although higher rates in female patients, worse PS, and limitation of treatment field were seen in the oldest old group, there were no significant difference in terms of the rate of treatment completion, effectiveness, and adverse events between the two groups. Our study showed radiotherapy is effective and well tolerated in patients aged 85 or older. Considering the oldest old requiring radiotherapy

  4. Malignancies and infection due to the human immunodeficiency virus. Are these emerging diseases?

    Valencia Ortega, M E

    2018-04-01

    Since the start of the human immunodeficiency virus (HIV) epidemic, tumour disease among patients has been significant. The collection of malignancies can be divided primarily into 2 groups: those associated with HIV (all of which are related to viral diseases) and those not associated with HIV (only some of which are associated with viral diseases). The origin of these malignancies is multifactorial, and the main causes that have led to an increase in tumour disease are immunosuppression, coinfection with oncogenic viruses and life prolongation secondary to the use of antiretroviral therapy. Establishing the general characteristics of the undiagnosed AIDS tumours is difficult, mainly because they are a highly heterogeneous group formed by malignancies of a diverse nature. The treatments do not differ from those used in the general population, although the management can be more difficult due to the late diagnosis, drug interactions and associated comorbidities.

    To study the clinical significance of determination of serum B7-H4 in patients with malignant hematologic diseases. Serum B7-H4 levels were determined in 65 patients with leucemia, 34 patients with lymphoma, 12 patients with multiple myeloma as well as in 50 healthy controls. The serum B7-H4 levels in patients with lymphoma [(38.81+/-10.34) kappag/L] were significantly higher than healthy controls [(31.62+/-9.850) kappag/L] (Pleucemia, patients with multiple myeloma and healthy controls. These results suggest that the B7-H4 may correlated with lymphoma, but uncorrelated with leucemia and multiple myeloma. Measurement of serum B7-H4 level provide useful information for distinctive diagnosis of different kinds of malignant hematologic diseases.

    The method of scan-guided fine needle aspiration biopsy of the liver is described, and the diagnostic value of this combined method in the diagnosis of malignant hepatic disease is evaluated in 83 confirmed cases, showing a specificity of 100% and a sensitivity of 94%. The combined method is compared to liver scanning alone and to Menghini biopsy. Different methods for the diagnosis of malignant hepatic disease are discussed, and it is concluded that scan-guided fine needle aspiration biopsy has a diagnostic value only obtainable otherwise by a combination of liver scanning and biopsy during laparoscopy. Cytologic features in the two most common tumor types in this study, i.e., metastatic colonic adenocarcinoma and hepatocarcinoma, are presented along with a brief discussion of the specificity of the cytologic diagnosis of hepatocarcinoma

    Extramammary Paget's disease (EMPD) is a rare clinical entity and can be associated with other malignancies. We analyzed our experience for prognosis and impact of therapy on outcomes. We conducted a retrospective review of all patients (n = 33) with EMPD treated at a tertiary care center from 1971 to 1998. Pathologic features of EMPD, concurrent secondary malignancies, and the effect of operations on recurrence were analyzed. Overall survival was compared with that of the general population. Male-to-female ratio was 4:29, and median age was 70 years. Median followup was 68 months, and no patient died from EMPD. The lesion was predominantly found on the vulva (76%). Patch-like, nonconfluent growth was present in 45% of patients, and no patient had pathologic lymph nodes. The most common signs and symptoms were irritation or pruritus (73%) and rash (61%). The presence of patches, invasive tumor growth, or a second malignancy were significantly associated with a higher recurrence rate. The type of operation, either local excision or hemivulvectomy, was not related to the time to recurrence. Complete gross resection was achieved in 94% of cases. Fifty-six percent of patients had microscopically positive margin and this correlated with a significantly higher recurrence rate (p = 0.002). The tumor recurred clinically in 14 of 33 patients (42%) after a median of 152 months (range 5 to 209 months). In those patients, between one and six reexcisions were performed. In 14 of 33 patients with EMPD (42%), 16 concurrent secondary malignancies were found. Overall survival rates for EMPD patients were similar to those of the general population. EMPD is an infrequently diagnosed disease that is preferably managed with complete local excision and reexcisions if needed. A thorough search for frequently occurring secondary malignancies might be beneficial to provide the best outcomes for these patients. Copyright 2003 by the American College of Surgeons

    Objective was to determine the underlying cause of superficial skin ulcers over a 15-year period. A retrospective histopathological analysis of 670 cases of superficial skin ulcers diagnosed in the Dept. of Pathology, Ahmadu Bello University Teaching Hospital, Zaria, Nigeria from January 1991 to December 2005. A total of 670 superficial skin ulcers were analyzed. The mail to female gender ratio was 409:261(1.5:1.0) and a peakage frequency of 44.3 %( 297) in the 5th and 6th decades. Spectrum of lesions encountered was categorized into inflammatory, infections, benign and malignant diseases. The malignant lesions were 309 (46.1%), non-specific inflammation 302 (45.1%), granulation tissue 25 (3.7%) and pseudoepitheliomatous hyperplasia 14 (2.1%). A total of 18(2.7%) specific infections were encountered, which included bacterial, fungal and viral infection. Benign lesions were 2(0.3%), comprising of neurofibroma and Bowen's disease. The most common malignant lesion was squamous cell carcinoma 203 (30.3%) with a male to female ratio of 128:75 (1.7:1.0). Of these 161 were well differentiated tumors. The lower limb was the prevalent site distribution of all the ulcers. Superficial ulcers may be harbinger of malignant diseases. Squamous cell carcinoma remains the most common malignant lesion arising from chronic superficial ulcers from our setting. Adequate tissue biopsy and early diagnosis may reduce the attendant morbidity of these ulcers. (author)

    Direct insurance claims tabulation and risk adjustment statistical methods can be used to estimate health care costs associated with various diseases. In this third manuscript derived from the new national Burden of Skin Disease Report from the American Academy of Dermatology, a risk adjustment method that was based on modeling the average annual costs of individuals with or without specific diseases, and specifically tailored for 24 skin disease categories, was used to estimate the economic burden of skin disease. The results were compared with the claims tabulation method used in the first 2 parts of this project. The risk adjustment method estimated the direct health care costs of skin diseases to be $46 billion in 2013, approximately $15 billion less than estimates using claims tabulation. For individual skin diseases, the risk adjustment cost estimates ranged from 11% to 297% of those obtained using claims tabulation for the 10 most costly skin disease categories. Although either method may be used for purposes of estimating the costs of skin disease, the choice of method will affect the end result. These findings serve as an important reference for future discussions about the method chosen in health care payment models to estimate both the cost of skin disease and the potential cost impact of care changes.

    To evaluate the efficacy of endovascular management of lower extremity deep vein thrombosis (DVT) in patients with malignant disease. Between January 2002 and January 2008, six consecutive patients (5 male and 1 female, mean age-65 years) with lower extremity DVT and malignant disease underwent endovascular management. The duration of symptoms lasted 4-120 days (mean-31 days; 20 days or less in four patients and more than 20 days in two). A catheter-directed thrombolysis was performed via the ipsilateral popliteal vein or common femoral vein, used alone or combined with a percutaneous mechanical thrombectomy. Angioplasty or stent placement was performed in residual stenosis or occlusion of the vein. The follow-up period lasted 1-14 months (mean 7.6 months) and was performed via a color Doppler ultrasonography or computed tomographic venography. Technical success and relief from symptoms was achieved within two days was achieved in five patients. Minor hemorrhagic complications occurred in two cases: hematuria and a hematoma at the puncture site. Upon follow-up, a recurrent DVT occurred in three patients as well as a patent venous flow in two. One patient died within 1 month due to a metastatic mediastinal lymphadenopathy. Endovascular management of the lower extremity DVT is effective for quickly eliminating a thrombus, relieving symptoms, and decreasing hemorrhagic complications in patients with malignant disease.

Upon follow-up, a recurrent DVT occurred in three patients as well as a patent venous flow in two. One patient died within 1 month due to a metastatic mediastinal lymphadenopathy. Endovascular management of the lower extremity DVT is effective for quickly eliminating a thrombus, relieving symptoms, and decreasing hemorrhagic complications in patients with malignant disease

    An 80-year-old woman with Parkinson's disease was scheduled for open heart surgery to repair thoracic aortic aneurysm. Parkinson's symptoms were normally treated using oral levodopa (200 mg), selegiline-hydrochloride (5 mg), bromocriptine-mesilate (2 mg), and amantadine-hydrochloride (200 mg) daily. On the day before surgery, levodopa 50mg was infused intravenously. Another 25 mg of levodopa was infused immediately after surgery. Twenty hours later, the patient developed tremors, heyperventilation, but no obvious muscle rigidity. Two days after surgery, the patient exhibited high fever, hydropoiesis, elevated creatine kinase, and a rise in blood leukocytes. She was diagnosed with neuroleptic malignant syndrome. She was intubated, and received dantrolene sodium. Symptoms of neuroleptic malignant syndrome disappeared on the fourth postoperative day. The stress of open heart surgery, specifically extracorporeal circulation and concomitant dilution of levodopa, triggered neuroleptic malignant syndrome in this patient. Parkinson's patients require higher doses of levodopa prior to surgery to compensate and prevent neuroleptic malignant syndrome after surgery.

    Current research efforts have mainly concentrated on evaluating the role of substances present in animal food in the aetiology of chronic diseases in humans, with relatively little attention given to evaluating the role of transmissible agents that are also present. Meat workers are exposed to a variety of transmissible agents present in food animals and their products. This study investigates mortality from non-malignant diseases in workers with these exposures. A cohort mortality study was conducted between 1949 and 1989, of 8520 meat workers in a union in Baltimore, Maryland, who worked in manufacturing plants where animals were killed or processed, and who had high exposures to transmissible agents. Mortality in meat workers was compared with that in a control group of 6081 workers in the same union, and also with the US general population. Risk was estimated by proportional mortality and standardised mortality ratios (SMRs) and relative SMR. A clear excess of mortality from septicaemia, subarachnoid haemorrhage, chronic nephritis, acute and subacute endocarditis, functional diseases of the heart, and decreased risk of mortality from pre-cerebral, cerebral artery stenosis were observed in meat workers when compared to the control group or to the US general population. The authors hypothesise that zoonotic transmissible agents present in food animals and their products may be responsible for the occurrence of some cases of circulatory, neurological and other diseases in meat workers, and possibly in the general population exposed to these agents.

    Full Text Available Introduction. Hepatitis B, a complication of blood transfusion or other means of transmission, occurs with variable frequency in children with malignant diseases. Objective. The objective of this study was to determine the frequency of hepatitis B virus infection in children with malignant diseases, to investigate the clinical course of the illness, and to analyze the influence of hepatitis on cytotoxic treatment. Method. The study included children diagnosed and treated for malignant diseases at the University Children's Hospital in Belgrade from 1997 to 2003. HBs Ag was analyzed in all patients who had elevated transarninases of twice normal value, in children who had icterus, and in one group of patients treated routinely after 2001 before, during, and after therapy. Results. A total of 137 male and 107 female children who had malignancies were treated. From 113 children who were evaluated for the presence of HBs Ag at the beginning of treatment, 2(1.7%] were HBsAg+. In this group of patients HBsAg was tested in 58 (51% children during and after chemotherapy, and HBsAg was discovered in 17 (29% of them. Of 123 children, in whom HBsAg was not tested at the beginning of their illness, 36 (55% out of 66 (51% tested patients were HBsAg+. No statistical difference between those two groups of patients was ascertained (X2=3.27, p>0.05. In summary, the presence of HBsAg was discovered in 53 patients, 22% out of 244 patients and 43% of tested patients. Nine patients had the icteric form of illness, with one case proving fatal due to fulminating hepatitis. Conclusion. Taking into consideration the uncertain long-term prognoses of these patients, follow-up and treatment is essential.

    Full Text Available In humans, gain-of-function (GOF mutations in RHBDF2 cause the skin disease tylosis. We generated a mouse model of human tylosis and show that GOF mutations in RHBDF2 cause tylosis by enhancing the amount of amphiregulin (AREG secretion. Furthermore, we show that genetic disruption of AREG ameliorates skin pathology in mice carrying the human tylosis disease mutation. Collectively, our data suggest that RHBDF2 plays a critical role in regulating EGFR signaling and its downstream events, including development of tylosis, by facilitating enhanced secretion of AREG. Thus, targeting AREG could have therapeutic benefit in the treatment of tylosis.

    Full Text Available Background: Inguinal lymph node dissection (ILND is associated with a high rate of morbidity. To evaluate the clinical benefit of surgical adhesives to reduce complications in patients undergoing ILND, we compared the use of TissuGlu Surgical Adhesive and ARTISS fibrin sealant with a control population. Material and methods: We conducted a retrospective analysis of patients undergoing ILND for metastatic malignant skin tumors at one hospital, Fachklinik Hornheide (Münster, Germany, from January 2011 through September 2013, assessing 137 patients with a total of 142 procedures. Results: Complications occurred in 22/60 procedures in the TissuGlu group (TG, in 8/17 in the ARTISS group (AG, and in 29/65 in the control group (CG. Prolonged drainage and seroma were recorded in four (23.5%, and 26 (40% respectively (non-significant. TG showed less extended drainage vs. CG (p=0.082. Mean daily drain volumes were significantly lower in AG vs. CG (p=0.000. With regard to wound infection, there was a 15% reduction in TG and 74% increase in AG group. Revision surgery was reduced by 36% in TG and increased by 54% in AG. Mean daily drain volumes were significantly lower in AG vs. CG (p=0.000. Mean total post-operative drain volume was lower in TG and AG vs. CG (p<0.001 among groups, CG vs. TG p<0.001, CG vs. AG p<0.001. The mean body mass index (BMI was significantly higher in patients with complications, 29.4±5.8 vs. 25.3±4.1 (p=0.000.Conclusion: The use of TissuGlu in our ILND patients was associated with a reduction in post-operative wound related complications and the need for revision surgeries compared to the control group. Daily drainage was significantly lower within the first 7 post-operative days with the use of ARTISS, but the benefit was lost due to the higher occurrence of wound infection and revision surgery. BMI above 29 is a risk factor for complications following ILND.(Level of evidence: level IV, retrospective case study

    Antibody dependent cellular cytotoxicity (ADCC) is a recently described mechanism of immunologic lysis in which cellular targets sensitized by specific antibodies are efficiently and selectively lysed by Fc receptor (FcR) bearing nonspecific effectors. Immunoglobulins of various classes (IgG, IgM, IgA, IgE) and various cellular effectors (large granular lymphocytes, monocyte/macrophages, T lymphocytes, neutrophils, and eosinophils) can induce ADCC in vitro, and the importance of ADCC in vivo is being tested experimentally in resistance to viral, bacterial, and parasitic infection, in tumor surveillance, in allograft rejection, and in inflammatory diseases. There is much indirect evidence that ADCC may be the mechanism of damage of different cellular targets in skin diseases, but the best direct evidence concerns immunologic keratinocyte damage, especially in cutaneous lupus erythematosus (LE). The authors have shown that keratinocytes of several species are highly susceptible to lymphocyte and monocyte-mediated ADCC, but not to neutrophil or eosinophil ADCC in vitro using two different cytotoxicity assays. In contrast, complement was a relatively ineffective mediator of lysis of metabolically intact keratinocyte targets. Patients with certain cutaneous lupus syndromes have serum antibodies capable of inducing monocyte and lymphocyte ADCC of targets coated with extractable nuclear antigens. The authors have shown that these antigens apparently move to the cell membrane of keratinocytes in vitro following ultraviolet irradiation. In an animal model, they have shown that antibodies to SSA/Ro bind to human keratinocytes in vivo, especially after ultraviolet irradiation

    Occupational skin disease (OSD) is a common occupational disease. Although primary prevention strategies are known, OSDs remain prevalent in a variety of work environments including the service sector (restaurant/food services, retail/wholesale, tourism/hospitality and vehicle sales and service). To obtain information about awareness and prevention of OSD in the service sector. Focus groups and a survey were conducted with two groups. The first consisted of staff of the provincial health and safety association for the service sector and the second group comprised representatives from sector employers. Focus groups highlighted key issues to inform the survey that obtained information about perceptions of awareness and prevention of OSD and barriers to awareness and prevention. Both provincial health and safety association staff and sector employer representatives highlighted low awareness and a low level of knowledge of OSD in the sector. Barriers to awareness and prevention included a low reported incidence of OSD, low priority, lack of training materials, lack of time and cost of training, lack of management support and workplace culture. A starting point for improving prevention of OSD in the service sector is increased awareness. Identification of the barriers to awareness and prevention will help to shape an awareness campaign and prevention strategies. Building on existing experience in Europe will be important. © The Author 2016. Published by Oxford University Press on behalf of the Society of Occupational Medicine. All rights reserved.

    Full Text Available Objective: Laparoscopic resection is the gold standard for treatmentof benign adrenal lesions. Laparoscopic resection of malignant lesions,however, is controversial, and there are only limited series publishedin the literature. The aim of this study is to describe technical aspectsand oncological results of laparoscopic adrenalectomy for malignantdisease. Methods: Eight patients (five men and three womenunderwent laparoscopic adrenalectomy for primary or metastaticadrenal malignancy. The procedures were performed transperitoneallyin two cases and retroperitoneally in 6 cases. Results: The meanincision size was 5 cm (4-9 cm, the mean duration of surgery was135 minutes and the mean blood loss was 250 ml. There was onecase of postoperative pneumonia, which progressed favorably.Histopathological diagnosis was metastasis in four cases and primaryadrenal neoplasm in four cases. There were two cases of systemicrecurrence in patients with metastatic adrenal cancer which originatedfrom breast-cancer in one case and lung cancer in another case. Localrecurrence or implantations on the trocar sites were not observed.All patients with primary adrenal neoplasms and 50% of those withmetastatic lesions of the adrenal were alive at the end of the follow-upperiod. Conclusion: Treatment of adrenal malignant disease can besafely performed through videolaparoscopy in patients with primaryadenocarcinoma or adrenal gland metastasis.

    Serum and bile tumor markers are under intense scrutiny for the diagnosis of malignant disease. The purpose of our study was to report the usefulness of serum and bile tumor markers for the discrimination between benign and malignant pancreatobiliary diseases. Between March 2010 and May 2013, 95 patients with obstructive jaundice or history of biliary obstruction, were included in the study. During ERCP, bile samples were obtained for measurement of tumor markers CEA, CA19- 9, CA125, CA72-4 and CA242. Serum samples were taken before ERCP for the same measurements. The patients were divided into two groups: patients with malignant disease and patients with benign disease. Serum tumor marker levels were significantly higher in patients with malignant disease. Serum CA242 and CA19-9 exhibited the highest diagnostic accuracy (76.8% and 73.7%, respectively). CA125 and CA72-4 levels in bile samples were significantly higher in patients with malignant disease. Bile CA125, CEA and CA72-4 achieved the best diagnostic accuracy (69, 65 and 65), respectively). The combined detection of CA19-9, CA242 in serum and CA125, CA72-4 in bile along with total bilirubin levels, showed the best diagnostic accuracy (81%). Serum and bile tumor markers, when studied alone, lack the diagnostic yield to discriminate benign from malignant pancreatobiliary diseases. In cases of diagnostic dilemmas the combination of serum and bile markers might be helpful.

    AIM: The aim of this study was to examine the spectrum of spinal canal disease in patients with known malignancy using magnetic resonance imaging (MRI). MATERIALS AND METHODS: One hundred and fifty-five patients underwent a total of 159 spinal MRI examinations over a three-year period. Patients were examined using a 1.0T magnet and a phased array surface spine coil. Sagittal T1 weighted spin echo and STIR sequences were routinely employed. Axial T1 and T2 weighted spin echo images were obtained at sites of identified pathology. Contrast enhanced sagittal and axial T1 weighted spin echo images were acquired when the unenhanced appearances did not correlate with the clinical findings or when the images suggested intradural or intramedullary disease. RESULTS: Malignant disease affecting the spinal cord or cauda equina was noted in 104/159 (65%) patients (extradural n= 78, intradural n= 20, intramedullary n= 7); one patient had evidence of both intradural and intramedullary deposits. Multiple levels of extradural cord/cauda equina compression were present in 18/78 patients (23%). The thoracic spine was the most frequently affected (74%). Bone elements were the major component of extradural compression in 11/78 patients (14%). Intradural metastases were multiple in 15/20 patients (75%). Four of the six solitary intramedullary metastases were situated in the conus medullaris. CONCLUSION: Magnetic resonance imaging of the entire spine is the investigation of choice in patients with known malignancy and suspected spinal canal disease. Contrast-enhanced images should be acquired when the unenhanced appearances do not correlate with the clinical findings or when they suggest intradural or intramedullary disease. Loughrey, G.J.

    The healthcare sector ranked in second place among economic sectors in the Czech Republic, with about 11.4 % of all occupational diseases in 2009. Skin diseases constituted about 20 % of all occupational diseases. The aim of this study was to analyze the causes and trends in allergic and irritant-induced skin diseases in the healthcare sector. The data concerning occupational skin diseases (Chapter IV of the Czech List of Occupational Diseases, non-infectious skin illnesses) in the healthcare sector were analyzed from the Czech National Registry of Occupational Diseases from 1997 until 2009. The trends in the total counts and most frequent causes were evaluated. During the past 13 years, a total of 545 skin diseases were acknowledged in healthcare workers. Allergic contact dermatitis was diagnosed in 464 (85 %), irritant contact dermatitis in 71 (13 %) and contact urticaria in 10 subjects (2 %). Ninety-five percent of the patients were females. The overall incidence in individual years varied between 1.0 and 2.9 cases per 10,000 full-time employees per year. Disinfectants were the most frequent chemical agents causing more than one third of all allergic skin diseases (38 %), followed by rubber components (32 %) and cleaning agents (10 %). A general downward trend of diagnosed cases of occupational skin diseases in heath care workers in the Czech Republic over the past 13 years was demonstrated.

    Previously, we showed that administration of a high-fat diet (HF-diet) to C57BL/6 mice exacerbates their response to short-term UVB radiation-induced inflammation in the skin. To explore the effects of an HF-diet on UVB-induced tumorigenesis, we have used the SKH-1 hairless mouse model in which the mice are exposed to UVB radiation (180 mJ/cm{sup 2}) three times a week for 24 weeks. The development of UVB-induced skin tumors was rapid and the tumor multiplicity and tumor size were significantly higher (P < 0.01–0.005) in the mice fed an HF-diet than the mice fed a control-diet (C-diet). Moreover, the malignant progression of UVB-induced papillomas to carcinomas was higher in HF-diet-fed mice. On analysis of tumors and tumor-uninvolved skin samples from the tumor-bearing mice, we found that administration of an HF-diet significantly enhanced the levels of UVB-induced expression of cyclooxygenase-2 (COX-2), prostaglandin E{sub 2} (P < 0.01), and PGE{sub 2} receptors, and activation of NF-κB in the UVB-exposed skin as well as in tumors. In addition the HF-diet enhanced the expression of proinflammatory cytokines, including tumor necrosis factor-α (P < 0.01), interleukin (IL)-1β (P < 0.01) and IL-6 (P < 0.05) in the UVB-exposed skin as well as in tumors. Western blot analysis revealed that HF-diet enhanced the levels of epidermal cell proliferation, phosphatidylinositol 3-kinase and phosphorylation of Akt at Ser{sup 473} in UVB-exposed skin and skin tumors. Collectively, these data demonstrate that the regular consumption of an HF-diet increases the risk of photocarcinogenesis in mice and that this is associated with enhanced expression of inflammatory mediators in the UVB-exposed skin and tumors. - Highlights: • Consumption of high-fat diet increases UVB-induced skin tumor development in mice. • Intake of high-fat diet stimulates progression of UV-induced papilloma to carcinoma. • Intake of high-fat diet enhances inflammation in UV-exposed skin • Regular

    Immunohistochemical detection of cold shock proteins is predictive for deleterious outcome in various malignant diseases. We recently described active secretion of a family member, denoted Y-box (YB) protein-1. We tested the clinical and diagnostic value of YB-1 protein fragment p18 (YB-1/p18) detection in blood for malignant diseases. We used a novel monoclonal anti-YB-1 antibody to detect YB-1/p18 by immunoblotting in plasma samples of healthy volunteers (n = 33), patients with non-cancerous, mostly inflammatory diseases (n = 60), hepatocellular carcinoma (HCC; n = 25) and advanced solid tumors (n = 20). YB-1/p18 was then tested in 111 patients with chronic liver diseases, alongside established tumor markers and various diagnostic measures, during evaluation for potential liver transplantation. We developed a novel immunoblot to detect the 18 kD fragment of secreted YB-1 in human plasma (YB-1/p18) that contains the cold-shock domains (CSD) 1-3 of the full-length protein. YB-1/p18 was detected in 11/25 HCC and 16/20 advanced carcinomas compared to 0/33 healthy volunteers and 10/60 patients with non-cancerous diseases. In 111 patients with chronic liver disease, YB-1/p18 was detected in 20 samples. Its occurrence was not associated with advanced Child stages of liver cirrhosis or liver function. In this cohort, YB-1/p18 was not a good marker for HCC, but proved most powerful in detecting malignancies other than HCC (60% positive) with a lower rate of false-positive results compared to established tumor markers. Alpha-fetoprotein (AFP) was most sensitive in detecting HCC, but simultaneous assessment of AFP, CA19-9 and YB-1/p18 improved overall identification of HCC patients. Plasma YB-1/p18 can identify patients with malignancies, independent of acute inflammation, renal impairment or liver dysfunction. The detection of YB-1/p18 in human plasma may have potential as a tumor marker for screening of high-risk populations, e.g. before organ transplantation, and should

    Lymph nodes (LN) and lymphatic drainage were identified by lymphoscintigraphy using 99m Tc-phytate in order to map the sentinel lymph nodes (SLNs) in patients with malignant skin neoplasms of the lower extremities, and to compare the results with an atlas of Japanese lymphatic anatomy. Sentinel lymphoscintigraphs of 18 patients with malignant skin neoplasms of the lower extremities (9 men, 9 women; age range 45-84 years, mean age 66 years) were analyzed retrospectively, and the LNs detected were identified as SLNs or secondary nodes. The patterns of lymphatic drainage were divided into three different categories: initial drainage into inguinal LN without visualization of popliteal LNs (inguinal type), initial drainage into popliteal LNs and then into intrapelvic LNs (popliteal type), and initial drainage into both popliteal and inguinal LNs (inguinal and popliteal type). More than half of the cases were the inguinal and popliteal type, as both inguinal and popliteal LNs were identified as SLNs. In the cases in which the hallux and its surrounding area were injected, all were the inguinal type and popliteal LNs were not visualized. In one case, only dynamic images detected lymphatic drainage without visualization of popliteal LNs. In contrast to the previously published literature on Japanese lymphatic anatomy, SLN lymphatic drainage from the skin of the lower extremities was wide and overlapping in many areas. However, in agreement with currently accepted anatomy, only the great saphenous lymphatic vessel drained the skin of the hallux and its surrounding area. The present results suggest that it is important to confirm lymphatic drainage in order to identify SLNs in the lower extremities. The patterns of lymphatic drainage from the skin of the foot were divided into three different categories. In contrast to previously published Japanese lymphatic anatomy, lymphatic drainage from the skin of the lower extremities was wide and overlapping in many areas. However

    The human skin is a well-organized organ bearing different types of cells in a well-structured interference to each other including epidermal and follicular keratinocytes, sebocytes, melanocytes, dermal papilla cells and fibroblasts, endothelial cells, sweat gland cells as well as nerves. Several hormones act on different cell types of the skin, while it is also considered an endocrine organ secreting hormones that act at several sites of the organism. GH receptors are found in almost all cell types forming the skin, while IGF-1 receptors' expression is restricted to the epidermal keratinocytes. Both Growth Hormone (GH) excess, as in the case of Acromegaly in adults, or Gigantism in growing children, and GH deficiency states lead to skin manifestations. In case of GH excess the main dermatological findings are skin thickening, coarsening of facial features, acrochordons, puffy hands and feet, oily skin and hyperhidrosis, while GH deficiency, on the contrary, is characterized by thin, dry skin and disorder of normal sweating. Moreover, special disorders associated with GH excess may have specific characteristics, as is the case of café-au-lait spots in Neurofibromatosis, or big café-au-lait skin hyperpigmented regions with irregular margins, as is the case in McCune-Albright syndrome. Meticulous examination of the skin may therefore contribute to the final diagnosis in cases of GH-induced disorders.

    Full Text Available Background/Aim. Oral candidiasis frequently causes discomfort in patients treated for malignant diseases, acting as well as a potential source of systemic infection. This disease may present itself through different clinical manifestations of both acute or chronic type. The aim of this study was to identify different Candida species from oral cavities of patients suffering from malignant diseases. Methods. Thirty patients admitted to the hospital for diagnostics/treatment of malignant diseases were included in this investigation. All subjects had visible changes of oral mucosa in the form of pseudomembranes and inflammation corresponding to oral candidiasis. Control group included 30 non-hospitalized patients diagnosed with candidiasis. Diagnosis of oral candidiasis was confirmed in all patients by microbiological analysis of tongue swabs. For microbiota identification, three different tests were used: germination test, fungal growth test on corn meal agar, and biochemical identification with commercially available ID 32 C kit (bio-Merieux, Marcy-l´Etoile, France. Results. Out of 30 isolates collected from hospitalized patients, 90% was related to Candida albicans, 7% was identified as Candida kefyr, and 3% as Candida famata. In samples collected from non-hospitalized controls, we isolated Candida albicans in 90% of the cases, in 7% Candida kefyr, while in 3% we identified Candida glabrata. Conclusion. Based on this investigation, oral candidiasis in patients treated with radiotherapy and chemotherapy is mainly caused by Candida albicans. It is to be expected that Candida albicans will remain the most significant causative agent of oral candidasis, although we must bear in mind the possibility of other pathogenic species.

    Full Text Available Increasing evidences indicate involvement of free radicals in the pathogenesis of benign and malignant breast diseases. Free radicals are highly reactive molecules and react with non–radicals in chain reaction leading to formation of new free radicals. If the defense mechanism of body fails to combat them, these free radicals pose a threat of injuring tissues by reacting with cell lipids. Lipids in the cell membrane undergo degradation to form hydroperoxides, which decompose to form a variety of products including malondialdehyde (MDA. MDA therefore was used as a marker to assess oxidative damage of cells and tissues. The aim of the present study was to assess the status of oxidative stress in the patients of benign and malignant breast diseases. Study has been made on the blood samples of 25 cases of benign breast disease and on an equal number of breast carcinoma patients. 20 healthy subjects were taken as the control cases.Mean MDA levels were significantly raised with depletion of antioxidant activity in all the patients in comparison to their control group suggesting the role of oxidative damage in the aetiopathogenesis of disease.

    The aim of this study is to find out the causes of skin diseases in one-third of the staff of a perfume factory, in which 10 different perfume sprays were being manufactured. Site inspection, dermatological examination and patch testing of all 26 persons at risk with 4 perfume oils and 30 ingredients of them. The results showed 6 bottlers were found suffering from allergic contact dermatitis, 2 from irritant contact dermatitis, 12 workers showed different strong reactions to various fragrances. The main causes of allergic contact dermatitis were 2 perfume oils (12 cases) and their ingredients geraniol (12 cases), benzaldehyde(9), cinnamic aldehyde (6), linalool, neroli oil, terpenes of lemon oil and orange oil (4 each). Nobody was tested positive to balsam of Peru. Job changes for office workers, packers or printers to other rooms, where they had no longer contact with fragrances, led to a settling. To conclude, automation and replacement of glass bottles by cartridges from non-fragile materials and using gloves may minimize the risk.

    Which are the essential global public health activities that should be carried out in order to attain the largest impact on poverty reduction and health improvement in the world? Since its foundation in 2001 the Human Mobile Population Committee (HMPC) has continued to devote its efforts to finding answers to this question, with a particular focus on the skin diseases of the Human Mobile Population (HMP) and other groups of disadvantaged people. In this article we present the model of socio-sanitary activity in the field of Migration, Poverty and Health of the Department of Preventive Medicine of Migration, Tourism and Tropical Dermatology (Dept.) at San Gallicano Institute--Research Institute for Hospitalization and Treatment (IRCCS)--in Rome (Italy). The activities of this dermatological centre are in the spirit of the HMPC's aims and we are of the opinion that this model is not only ethically valid, but also practically and economically convenient, and that there is evidence that our experience is worth repeating, in as many situations as possible, in the interest of public health.

    Shear wave elastography (SWE) is an emerging technique which can obtain quantitative elasticity values in breast disease. We therefore evaluated the diagnostic performance of SWE for the differentiation of breast masses compared with conventional ultrasound (US). Conventional US and SWE were performed by three experienced radiologists for 158 consecutive women who had been scheduled for US-guided core biopsy or surgical excision in 182 breast masses (89 malignancies and 93 benign; mean size, 1.76 cm). For each lesion, quantitative elasticity was measured in terms of the Young's modulus (in kilopascals, kPa) with SWE, and BI-RADS final categories were assessed with conventional US. The mean elasticity values were significantly higher in malignant masses (153.3 kPa ± 58.1) than in benign masses (46.1 kPa ± 42.9), (P masses as well as invasive and intraductal cancers with SWE. Our results suggest that SWE has the potential to aid in the differentiation of benign and malignant breast lesions.

    In this paper, the effects of hyperthermia on cells and immune system are introduced briefly. The mechanism of action of hyperthermia on human papilloma virus (HPV)-infected skin diseases was elaborated as an example in this paper. Many studies have proved that hyperthermia affects a number of cellular and molecu- lar constitutes in the skin immune system, involving both innate and adaptive immune responses; the efficacy of hyperthermia in treating some infectious and cancerous conditions has been validated and applied in clinics, while molecular mechanisms of hyperthermia affecting the immunereaction is still unclear.

    Directory of Open Access Journals (Sweden)

    Beth L. Thurberg, MD, PhD

    2017-06-01

    Full Text Available Fabry disease (FD is an X-linked lysosomal storage disorder caused by loss of function mutations in the GLA gene at Xq22 with subsequent functional deficiency of alpha-galactosidase A, resulting in the accumulation of globotriaosylceramide (GL-3 or Gb3 in multiple cells types throughout the body. As with other rare metabolic disorders, little is known about the incidence of malignancies in these populations and the relationship to the underlying disease, if any. We report the occurrence of meningioma in four female patients with Fabry disease. Two of the cases are from the same family and shared the same GLA mutation. All four patients underwent surgical excision of their tumor. High resolution light microscopy and electron microscopy examination of one case revealed extensive involvement of tumor cells and associated blood vessels by GL-3 accumulation. Because of the small number of Fabry-associated cancer cases reported in the literature, questions about a possible link between lysosomal storage disorders and the development of malignancy remain open.

    Dermatoscopy is at present the most powerful clinical method for early detection of malignant melanomas. However, the application requires a lot of expertise and experience. Therefore, a quantitative image analysis system has been developed in order to assist dermatologists in 'on site diagnosis' and to improve the detection efficiency. Based on a very extensive dataset of dermatoscopic images, recorded in a standardized manner, a number of features for quantitative characterization of complex patterns in melanocytic skin lesions has been developed. The derived classifier improved the detection rate of malignant and benign melanocytic lesions to over 90% (sensitivity =91.5% and specificity =93.4% in the test set), using only six measures. A distinguishing feature of the system is the visualization of the quantified characteristics that are based on the dermatoscopic ABCD-rule. The developed prototype of a dermatoscopic workplace consists of defined procedures for standardized image acquisition and documentation, components of a necessary data pre-processing (e.g. shading- and colour-correction, removal of artefacts), quantification algorithms (evaluating asymmetry properties, border characteristics, the content of colours and structural components) and classification routines. In 2000 an industrial partner will begin marketing the digital imaging system including the specialized software for the early detection of skin cancer, which is suitable for clinicians and practitioners. The primary used nonlinear analysis techniques (e.g. scaling index method and others) can identify and characterize complex patterns in images and have a diagnostic potential in many other applications.

    Lumpy skin disease caused by Capripoxvirus is at the moment the most important threat to European cattle industry. The only way for successful control of disease is fast and efficient diagnosis and vaccination. According to EU legislation, vaccination against LDS can be conducted only after confirmation of the disease. Croatia has a special position regarding LSD-in 2016, for the first-time vaccination of the entire cattle population was conducted without an index case. The presence of vaccine viral particles was detected in milk, skin nodules, blood and nasal swabs in seven from total of eight herds. The presence of virus genome was detected in five cows from 10 up to 21-day post-vaccination. The virus was successfully isolated on cell culture from 10 up to 21-day post-vaccination from three animals. The obtained results support the need for further efforts to develop safer vaccines against LSDV. © 2017 Blackwell Verlag GmbH.

    2014-03-01

    Full Text Available Malignant melanoma is a malignant neoplasia drives from melanocytes. Malignant melanoma, the most causing death, is seen in the third place at skin cancer. Malignant melanoma shows intrinsic resistance to chemotherapeutic agents and variability in the course of the disease which are distinct features separating from other solid tumors. These features prevent the development and standardization of non-surgical treatment models of malignant melanoma. Although there is a large number of chemotherapeutic agents used in the treatment of metastatic malignant melanoma, it hasn’t been demonstrated the survival advantage of adjuvant treatment with chemotherapeutic agents. Because of the different clinical course of malignant melanoma, the disease is thought to be closely associated with immune system. Therefore, immunomodulatory therapy models were developed. Mistletoe stimulates the immune system by increasing the number and activity of dendritic cells, thus it has been shown to effect on tumor growth and metastasis of malignant melanoma patient. Outlined in this review are the recent developments in the understanding the role of mistletoe as a complementary therapy for malignant melanoma. J Clin Exp Invest 2014; 5 (1: 145-152

    Surgery is the treatment of choice for symptomatic tracheal obstruction due to benign or malignant thyroid disease. In case of inoperability, or when surgery is refused, few therapeutic alternatives are available. Interventional bronchoscopic procedures have only been reported anecdotally. The objective of this study is to evaluate the results of interventional bronchoscopic procedures in the treatment of severe tracheal obstruction due to thyroid disease. Retrospective cohort analysis. University hospital, tertiary referral center. Thirty consecutive patients referred for bronchoscopic treatment of benign (n = 17) or malignant (n = 13) thyroid-related upper airway obstruction due to tracheomalacia, extrinsic compression, and/or tracheal ingrowth. Indications for bronchoscopic treatment were medical or surgical inoperability, prevention or treatment of tracheomalacia, and refusal of surgery. There were no procedure-related complications. Rigid bronchoscopy with dilatation, stenting and/or Nd-YAG laser treatment, and clinical follow-up. Subjective improvement, pulmonary function tests, early and late complications, and survival. In the benign group, immediate (100% relief of dyspnea) and long-term (88% relief of dyspnea) results were excellent after airway stenting (21 stents used in 17 patients). There was one unrelated death 1 week after stenting in a 98-year-old patient. There were 6% and 30% short-term and long-term complications, respectively, that could be managed endoscopically. In the malignant group, Nd-YAG laser treatment (n = 3) and stenting (n = 13) yielded immediate and long-term success in 92% of patients. There were 15% short-term and 8% long-term complications. Median survival time was 540 days. Interventional bronchoscopic procedures including Nd-YAG laser treatment and stenting are valuable alternatives to surgery in inoperable thyroid-induced tracheal obstruction, or when surgery is refused.

    2015-01-01

    Occupational skin disease is a common problem among health care workers (HCWs). The prevalence of occupational skin disease in HCWs has been reported in several international studies, but not in the UK. To estimate the prevalence of occupational skin disease in a population of UK HCWs and to explore possible causative factors. Clinical and non-clinical HCWs attending for an influenza vaccine during October and November 2013 were invited to complete a brief skin questionnaire. Data from staff who stated their skin had suffered as a result of work were compared with data from staff who did not, to explore differences in potential causative factors. A total of 2762 questionnaires were analysed. The estimated prevalence of occupational skin disease was 20% for clinical and 7% for non-clinical staff. In total, 424 clinical staff stated their skin had been made worse by work. There were statistically significant differences between clinical staff with and without reported skin symptoms regarding a history of eczema, frequent hand washing and moisturizer use but no statistically significant difference in the relative proportions of soap and alcohol hand gel use. Non-clinical staff reported significantly more use of soap relative to alcohol gel than clinical staff. This study demonstrated the prevalence of occupational skin disease in a population of UK HCWs. More work is indicated to explore if the ratio of soap and alcohol gel reported in this study are typical and whether this has any impact on the development of occupational skin disease. © The Author 2014.

  19. Cancer and Scleroderma: A Paraneoplastic Disease with Implications for Malignancy Screening

    Science.gov (United States)

    Shah, Ami A.; Rosen, Livia Casciola

    2015-01-01

    Purpose of review Recent data suggest a paraneoplastic mechanism of scleroderma pathogenesis in unique subsets of scleroderma patients. In this article, we review these data, explore potential links between cancer and scleroderma, and propose an approach to malignancy screening in scleroderma. Recent findings Emerging data have demonstrated that patients with scleroderma and RNA polymerase III autoantibodies have a significantly increased risk of cancer within a few years of scleroderma onset. Genetic alterations in the gene encoding RNA polymerase III (POLR3A) have been identified, and patients with somatic mutations in POLR3A have evidence of mutation specific T cell immune responses with generation of cross-reactive RNA polymerase III autoantibodies. These data strongly suggest that scleroderma is a by-product of anti-tumor immune responses in some patients. Additional epidemiologic data demonstrate that patients developing scleroderma at older ages may also have a short cancer-scleroderma interval, suggestive of paraneoplastic disease. Summary Scleroderma may be a paraneoplastic disease in unique patient subsets. Aggressive malignancy screening in these patients may aid in early cancer detection. Further study is required to determine whether cancer therapy could improve scleroderma outcomes in this patient population. PMID:26352736

    Bactibilia has several consequences to human health. Assessing the bile microbiology of patients with biliopancreatic diseases in order to identify bacteria and their possible infectious complications. Retrospective study of 30 bile culture samples from patients with benign and malignant biliopancreatic diseases. The samples were assessed to set the bile microbiological flora and to search for its possible link with comorbidity, carcinogenesis and postoperative infectious complications. Thirty bile samples from patients at mean age ≈57.7 years, mostly female (n=18), were assessed. Bactibilia was found in 12 cases, mostly in patients with benign diseases (n=8), older than 50 years (n=23) and female (n=10). Adenocarcinoma of the duodenal papilla (n=9) and cholelithiasis (n=8) were the most common diseases. Escherichia coli (n=5) and Klebsiella sp (n=3) were predominantly found in patients with benign diseases; and Klebsiella sp (n=2) and Streptococcus sp (n=2) were prevalent in cancer patients. There were postoperative infectious complications in seven cases, five of them in bactibilia-associated patients (P=0.084). Bactibilia was found in 12 samples and Escherichia coli and Klebsiella sp were most often identified in patients with benign diseases, as well as Streptococcus sp and Klebsiella sp in cancer patients. There was a trend of higher postoperative infectious complication incidence in patients with bactibilia.

  1. Potential of confocal laser scanning microscopy for non-invasive diagnostics of malignant epithelial skin tumors in the course of dermatoheliosis progression

    2016-01-01

    Full Text Available Most cases of malignant epithelial skin neoplasms including actinic keratosis and basal cell carcinoma, which are characterized by the most complicated course and numerous clinical and morphological options, involve dermatoheliosis progression. The risk of actinic keratosis transformation into basal cell carcinoma varies from 0.1% to 20% and up to 80% in cases of multiple AK lesion foci. A non-invasive method known as reflectance confocal laser scanning microscopy is the most promising one for the purposes of early diagnostics of signs pointing at epithelial skin neoplasm development and makes it possible to monitor the tumor in progress in vivo to diagnose the presence of a pool of squamous cells on a timely basis. The confocal laser scanning microscopy method provides high-contrast images of for any horizontal-oriented morphologic structures in the epidermis and upper dermis with a resolution comparable to those characteristic of traditional optical microscopy of skin tissue samples. According to our data obtained as a result of studying dynamic changes and morphologic structures in actinic keratosis foci (50 cases using the confocal laser scanning microscopy method, we discovered a number of morphologic features, and their further analysis will distinguish the signs of progressing carcinogenesis in case of dermatoheliosis.

    Repair of uv-light induced DNA damage and changes in the semiconservative DNA synthesis were studied by in vitro autoradiography in the skin of patients with lightdermatoses (polymorphous light eruption, porphyria cutanea tarda, erythropoietic protoporphyria) and xeroderma pigmentosum as well as in that of healthy controls. In polymorphous light eruption the semiconservative DNA replication rate was more intensive in the area of the skin lesions and in the repeated phototest site, the excision repair synthesis appeared to be unaltered. In cutaneous prophyrias a decreased rate of the repair incorporation could be detected. Xeroderma pigmentosum was characterized by a strongly reduced repair synthesis.

    We, in this study, describe how T lymphocytes in a skin biopsy can proliferate in vitro for up to 3 months by using T-cell growth factors - interleukin-2 (IL-2) and IL-4 yielding approximately 100-160 million T lymphocytes within 1 month. We established cell lines from three tuberculin skin tests......, four positive patch tests, 15 of 16 biopsies from atopic dermatitis (AD), 15 of 19 biopsies from mycosis fungoides (MF), 12 of 24 biopsies from psoriasis vulgaris, which was significantly less than AD (P lymphocytes (P ... to immediate halt of proliferation. Blood mononuclear cells from patients and biopsies from healthy persons never gave cell lines. All cells were T lymphocytes expressing CD45RO+, HLA-DR+ and CD150. The CD7 expression was significantly increased in cell lines from AD (P

    With the revision of the German Ordinance on Occupational Diseases, skin cancer due to UV irradiation was amended as a new occupational disease to the list of occupational diseases in Germany. The new occupational disease BK 5103 has the following wording: "Squamous cell carcinoma or multiple actinic keratosis of the skin caused by natural UV irradiation". Actinic keratoses are to be considered as multiple according to this new occupational diseases if they occur as single lesions of more than five annually, or are confluent in an area > 4 cm(2) (field cancerization). It is estimated that more than 2.5 million employees are exposed to natural UV irradiation due to their work (outdoor workers) in Germany and therefore have an increased risk of skin cancer. In this article the medical and technical prerequisites which have to be fulfilled for this new occupational disease in Germany are introduced.

    Ovarian cancer is the seventh most common cancer in women and the most frequent cause of gynaecological malignancy-related mortality in women. Currently, no standardized reliable screening test exists. MicroRNA profiling has allowed the identification of signatures associated with diagnosis, prognosis and response to treatment of human tumours. The aim of this study was to determine if a microRNA signature could distinguish between malignant and benign ovarian disease. A training set of 5 serous ovarian carcinomas and 5 benign serous cystadenomas were selected for the initial experiments. The validation set included 20 serous ovarian carcinomas and 20 benign serous cystadenomas. The serum\\/plasma focus microRNA Exiqon panel was used for the training set. For the validation set a pick and mix Exiqon panel, which focuses on microRNAs of interest was used. A panel of 4 microRNAs (let-7i-5p, miR-122, miR-152-5p and miR-25-3p) was significantly down regulated in cancer patients. These microRNAs target WNT signalling, AKT\\/mTOR and TLR-4\\/MyD88, which have previously been found to play a role in ovarian carcinogenesis and chemoresistance. let-7i-5p, miR-122, miR-152-5p and miR-25-3p could act as diagnostic biomarkers in ovarian cancer.

    We evaluated the characteristics of the benign and malignant nodules on transrectal ultrasound in diagnosis of prostatic disease. Histologic examination of the trans perineal prostatic biopsy of the total 47 cases resulted in 19 cases of BPH, 8 cases of prostatic cancer, and 20 cases of normal prostatic tissue group. The hypoechoic mass in peripheral zone on TRUS had high possibility of prostatic carcinoma and the isoechoic or mixed echogenic mass in central gland had high possibility of benign lesion. Hypoechoic haloes around nodules and cysts were noted in BPH and normal prostatic tissue group, that were compatible with benign lesion. The mean value of PSA was 12.0 ng/ ml in BPH, 8.5 ng / ml in normal prostatic tissue group, and 65.6 ng / ml in prostatic cancer, which was very high in prostatic cancer. Between BPH and normal prostatic tissue group, there was no demonstrable difference in location of nodule, pattern of calcification, and echogenicity of the nodules on TRUS. The size of prostatic gland was relatively smaller and mean value of PSA was lower in normal prostatic tissue group, compared with in BPH. In conclusion, the location of the nodules and PSA value are considered to be important in differentiation of the benign and malignant prostatic nodules

    From 1980 to 1988, 65 consecutive patients were treated with a program of intensive chemotherapy and total body irradiation (TBI) for malignant hematological diseases at the Institut Jules-Bordet. Results were analyzed according to different prognostic factors as well as to the radiation technique; 3 different schedules were used: 3 fractions of 2.66 Gy given in one day at 3-h intervals, 6 daily fractions of 2 Gy in 6 days and 7 fractions of 2.25 Gy in 8 days. The second radiation schedule appears to give the best results as relapses were higher with the 1-day program and there was an increase in later effects and early deaths with 7 fractions of 2.25 Gy. Nevertheless, the results indicate that after administration of 5 or 6 times 2 Gy TBI, there might be possible benefit in treating certain parts of the body by radiation, those in particular that could be sanctuary sites for malignant cells from chemotherapy. The authors propose a simple and easy way of uniformizing the radiation schedule to carry out a multicentric trial [fr

    Full Text Available Background. Dilation of malignant strictures in endoscopic ultrasound (EUS staging of esophageal cancer is safe, but no data exists regarding the subsequent development of metastases. Aim. Compare the rates of metastases in esophageal cancer patients undergoing EUS staging who require esophageal dilation in order to pass the echoendoscope versus those who do not. Methods. We reviewed consecutive patients referred for EUS staging of esophageal cancer. We evaluated whether dilation was necessary in order to pass the echoendoscope, and for the subsequent development of metastases after EUS at various time intervals. Results. Among all patients with similar stage (locally advanced disease, defined as T3, N0, M0 or T1-3, N1, M0, there was no difference between the dilated and nondilated groups in the rates of metastases at 3 months (14% versus 10%, =1.0, 6 months (28% versus 20%, =0.69, 12 months (43% versus 40%, =1.0, or ever during a mean followup of 15 months (71% versus 55%, =0.48. Conclusions. Dilation of malignant strictures for EUS staging of esophageal cancer does not appear to lead to higher rates of distant metastases.

    Highlights: •Conventional non-contrast MRI is unable to distinguish CKD pseudotumors from RCCs. •Pseudotumours in a background of CKD do not show restricted diffusion. •CKD pseudotumours demonstrate high ADC values whereas RCCs show restricted diffusion. •DW-MRI is reliable in ruling out malignancy incase of pseudotumours found in chronic kidney disease. •DW-MRI may obviate contrast administration and/or tissue sampling in renal pseudotumours and prevent inadvertent surgeries. -- Abstract: Objectives: To evaluate whether diffusion-weighted MRI (DW-MRI) can distinguish pseudotumours in chronic kidney disease (CKD pseudotumours) from renal-cell-carcinomas (RCCs) (with or without CKD) and whether it offers additional benefit over conventional MRI. Methods: One-hundred patients underwent MDCT, MRI and DW-MRI (at b-values of 0 and 500 s/mm 2 ) for evaluation of focal renal lesions. Of these, 20 patients with 40 CKD pseudotumours and 36 patients with 40 RCCs were retrospectively analyzed. T1-weighted, T2-weighted, diffusion-weighted images were evaluated, apparent-diffusion-coefficient (ADC) values were compared and receiver-operating-characteristic (ROC) curves were drawn to establish cut-off ADC-values. Results: 92.5% of CKD pseudotumours remained indeterminate after conventional MRI. On DW-MRI, none of them showed restricted diffusion and thus malignancy could be ruled out in 100% of the lesions. In contrast, all the solid RCCs showed diffusion restriction. Mean ADC-value for CKD pseudotumours was significantly higher than RCCs and surrounding diseased parenchyma [2.50 vs 1.56 (×10 −3 mm 2 /s) (P < 0.0001) and 2.05 (×10 −3 mm 2 /s) (P = 0.0001) respectively]. ROC analysis for differentiating CKD pseudotumours and RCC yielded high sensitivity (91.7%) and specificity (100%) for cut-off ADC-value of 2.04 (×10 −3 mm 2 /s). Conclusions: CKD pseudotumors usually remain indeterminate on conventional non-contrast MRI. DW-MRI can distinguish CKD pseudotumors

The most commonly reported adverse effects were generally well tolerated, mild to moderate. The main side effects were drowsiness, nausea, vomiting and dry mouth. There is evidence that cannabinoids are safe and modestly effective in neuropathic pain and also for relieving pain in patients with malignant diseases. The proportion of “responders” (patients who at the end of 2 weeks of treatment reported ≥30% reduction in pain intensity on a scale of 0–10, which is considered to be clinically important was 43% in comparison with placebo (21%. Conclusion: The target dose for relieving pain in patients with malignant diseases is most likely about 10 actuations per day, which is about 27 mg tetrahydrocannabinol (THC and 25 mg cannabidiol (CBD, and the highest approved recommended dose is 12 actuations per day (32 mg THC

    Full Text Available Background: Across the globe, skin disorders represent a frequent occupational concern for many health professionals including veterinarians and there is a serious impact of skin diseases on their lives and careers. But little is known about the prevalence and distribution of skin diseases (especially occupational within this important professional group across Asia, especially India. Materials and Methods: The study was a cross-sectional study carried out over a period of one year in which veterinarians and veterinary workers of Kashmir valley were screened for various skin diseases and occupational dermatoses. Results: The study group comprised 910 veterinarians and associated workers working across the valley with the majority being males; 846 workers (93%. The mean age of the group was 38.53 years. Out of these, 267 veterinarians and associated workers (29.3% were found to have skin lesions. Of the 267 cases, 165 (61.80% had non-infectious lesions, while the rest had 102 (38.20% had infectious skin diseases. The main non-infectious lesions included friction-related disorders, eczemas, pigmentary disorders, papulosquamous disorders, and many others; while the infectious lesions were of fungal, bacterial, viral, and parasitic etiology. Fungal infections, eczemas, and melasma were more common in them, indicating an occupational etiology. Conclusion: A huge group of skin diseases was seen in veterinarians and veterinary workers, with some diseases showing an occupational nature. To reduce the burden of skin diseases in this particular group, proper prevention measures need to be instituted at work places by veterinary governing bodies of the state.

    Little is known about the level of engagement and correlates of sun protection and skin self-exam among individuals diagnosed with melanoma. Participants (N = 229) completed measures of skin self-exam and sun protection practice and knowledge and attitudes. Approximately eighty-four percent of patients reported engaging in skin self-examination at least once in the past year. Engagement in sun protection practices was moderate. Self-exam practice was associated with gender, physician recommendation about self-exam, and perceived benefits and barriers of self-exam. Sun protection was associated with gender, age, medical status and health care access, physician recommendation, knowledge, and a number of psychological factors. Behavioral interventions to improve skin surveillance and sun protection may benefit from an emphasis on physician education regarding self-exam and sun protection, education regarding the efficacy of sunscreen and the risks associated with sunbathing, reducing perceived barriers to self-exam and sun protection, and reducing reliance on social influences on sun protection practices.

    Accelerated formation and tissue accumulation of advanced glycation end products (AGEs), reflecting cumulative glycemic and oxidative stress, occurs in age-related and chronic diseases like diabetes mellitus (DM) and renal failure, and contributes to vascular damage. Skin autofluorescence (AFR), a noninvasive measurement method, reflects tissue accumulation of AGEs. AFR has been reported to be an independent predictor of mortality in Caucasian hemodialysis patients. We assessed the relationship between levels of AFR and the prevalence of cardiovascular disease (CVD), and clarified the prognostic usefulness of skin AFR levels in Asian (non-Caucasian) hemodialysis (HD) patients. AFR was measured with an autofluorescence reader in 64 HD patients. Overall and cardiovascular mortality was monitored prospectively during the 3-year follow-up. During follow-up, CVD events occurred in 21 patients. The deaths of 10 HD patients were associated with CVD. Multivariate logistic regression analyses showed that initial AFR was an independent risk factor for de novo CVD in HD patients with or without diabetes. When patients were classified on the basis of AFR tertiles, Cochran-Armitage analysis demonstrated that the highest tertile of AFR level showed an increased odds ratio for the prevalence of CVD. These findings suggest that AFR levels can be used to detect the prevalence of CVD in HD patients with or without diabetes. © 2014 The Authors.

    Tissue accumulation of advanced glycation end-products (AGE) is thought to be a contributing factor to the progression of cardiovascular disease (CVD). Skin autofluorescence, a non-invasive measure of AGE accumulation using autofluorescence of the skin under ultraviolet light, has shown associations with CVD in haemodialysis patients. The present study aimed to evaluate relationships of skin autofluorescence to renal function as well as CVD in pre-dialysis patients with chronic kidney disease (CKD). Subjects in this cross-sectional analysis comprised 304 pre-dialysis CKD patients [median age, 62.0 years; median estimated glomerular filtration rate (eGFR), 54.3 mL/min/1.73 m(2); diabetes, n = 81 (26.6%)]. AGE accumulation in skin was assessed by skin autofluorescence using an autofluorescence reader. Relationships between skin autofluorescence, eGFR, CVD history and other parameters were evaluated. Skin autofluorescence correlated negatively with eGFR (r = -0.42, P skin autofluorescence with age, presence of diabetes, eGFR and CVD history in CKD patients (R(2) = 30%). Age, male gender, smoking history, skin autofluorescence and eGFR were significantly correlated with CVD history, and multiple logistic regression analysis identified age [odds ratio (OR), 1.09; 95% confidence interval (CI), 1.03-1.15; P skin autofluorescence (OR, 3.74; 95%CI, 1.54-9.24; P skin autofluorescence increased as GFR decreased and was related to CVD history in CKD patients. Non-invasive autofluorescence readers may provide potential markers for clinical risk assessment in pre-dialysis CKD patients.

    Humidity, along with other climatic factors such as temperature and ultraviolet radiation, can have an important impact on the skin. Limited data suggest that external humidity influences the water content of the stratum corneum. An online literature search was conducted through Pub-Med using combinations of the following keywords: skin, skin disease, humidity, dermatoses, dermatitis, eczema, and mist. Publications included in this review were limited to (i) studies in humans or animals, (ii) publications showing relevance to the field of dermatology, (iii) studies published in English and (iv) publications discussing humidity as an independent influence on skin function. Studies examining environmental factors as composite influences on skin health are only included where the impact of humidity on the skin is also explored in isolation of other environmental factors. A formal systematic review was not feasible for this topic due to the heterogeneity of the available research. Epidemiological studies indicated an increase in eczema with low internal (indoors) humidity and an increase in eczema with external high humidity. Other studies suggest that symptoms of dry skin appear with low humidity internal air-conditioned environments. Murine studies determined that low humidity caused a number of changes in the skin, including the impairment of the desquamation process. Studies in humans demonstrated a reduction in transepidermal water loss (TEWL) (a measure of the integrity of the skin's barrier function) with low humidity, alterations in the water content in the stratum corneum, decreased skin elasticity and increased roughness. Intervention with a humidifying mist increased the water content of the stratum corneum. Conversely, there is some evidence that low humidity conditions can actually improve the barrier function of the skin. Ambient relative humidity has an impact on a range of parameters involved in skin health but the literature is inconclusive. Further

    Physical symptoms of skin diseases have been shown to negatively affect patients' wellbeing. Although insight into physical symptoms accompanying skin diseases is relevant for the management and treatment of skin diseases, the prevalence of physical symptoms among patients with skin diseases is a rather unexplored territory. The goal of the present study was to examine the prevalence of physical symptoms of itch, pain and fatigue in patients with skin diseases. On the basis of a systematic morbidity registration system in primary care, questionnaires were sent to 826 patients with skin diseases. Eventually, questionnaires from 492 patients were suitable for our analyses. Results indicated that patients with skin diseases particularly experience symptoms of itch and fatigue. Approximately 50% of all patients report experiencing these symptoms and about 25% experience these symptoms as relatively severe. Pain was relatively less frequently reported by 23% of all patients, and was on average somewhat less intense. The physical symptoms showed relatively strong correlations with disease-related quality of life and self-reported disease severity. In contrast, only moderate correlations were found with comorbidity and demographic variables, which suggests that the physical symptoms of itch, pain and fatigue are consequences of the skin diseases. Itch and fatigue and, to a somewhat lesser extent, pain have a high prevalence among patients with skin diseases. Clinicians should be encouraged to carefully assess itch, pain and fatigue in patients with skin diseases, and where appropriate focus treatment to these symptoms.

    A Fourier spectrometer was used in order to measure the spectral emissivity E(k) of human skin in the FIR region k=190-420 cm-1. Three studies on patient groups with defined chronic diseases have been performed: patients with untreated bronchial carcinoma, patients with rheumatic arthritis and patients with chronic renal insufficiency. In comparison with a symptomfree control group all patient groups show significant differences in E(k). As result of a discriminant analysis a separation of 95.7% between carcinoma patients and control persons is possible. The separation quotes between the other groups indicate that patients with malignant neoplasms can be discriminated from other chronically ill persons.

    Control of hypertension is often a problem in the management of end stage renal disease (ESRD). Multiple modalities of treatment are required to prevent cardiovascular and cerebrovascular mortality and morbidity. These include fluid and salt restriction, multidrug regimes and dialysis. We report a case of young 25 years old patient, admitted with chronic renal failure, complicated by malignant and refractory hypertension, not responding to hemodialysis and antihypertensive agent. During stay in hospital, patient also had intracerebral hemorrhage, fits due to uncontrolled hypertension requiring ventilatory support followed. Renal transplant was considered to be the final therapeutic modality. After gradual recovery, a successful live-related renal transplant was performed. As soon as good graft was established, the blood pressure settled and 4 of the 5 antihypertensives were withdrawn. After 2 weeks, patient was discharged in a stable condition with a total stay of about 2 months. (author)

    Thirty-two second malignancies (21 acute leukemias and 11 solid tumors) were identified among 659 patients with all stages of Hodgkin's disease treated by members of the Southwest Oncology Group. There were no leukemias and one solid tumor among 95 patients treated with radiotherapy alone. The actuarial risk of developing acute leukemia at 7 years was 6.2% for chemotherapy alone, 6.4% for combined modality, and 7.7% for salvage chemotherapy. The incidence of acute leukemia was higher (P . 0.002) among those whose treatment began at greater than or equal to 40 years of age. The actuarial risk of leukemia in that group was 20.7% at 7 years. These data are compatible with the hypothesis that chemotherapy alone, combined modality, and salvage chemotherapy have an equivalent oncogenic potential and that patients greater than or equal to 40 years of age have an enhanced susceptibility to these oncogenic stimuli

    Background: The morbidity associated with skin diseases makes them an important public health problem. Very scanty literature is found on the problem which is either disease-based, community based or a specified population group-based. objective of this study was to assess the pattern of skin diseases in patients and to determine their relation with demographic characteristics. Methods: This descriptive study was conducted at dermatology out-patient department of liaquat university hospital, jamshoro, pakistan for the period from 10th january to 10th february 2008. Four hundred and eleven patients were enrolled during the study period. The study population comprised of newly diagnosed cases as well as relapsing cases presenting at the facility. The criterion for registering the patients was clinical diagnosis although few cases were supported by investigations, too. The data was collected through a pre-designed questionnaire and analysed through spss-12. Result: Skin problems are fairly common among children and women. in children of less than 10 years age, 82.5% visiting the facility suffer from infectious skin diseases. among the infectious diseases, scabies is highly prevalent disease (45.5%). the majority of the patients belong to rural or slum areas (77.2%), low socio-economic strata (68.9%), and living in overcrowded families (82%). a strong association between skin infections and water inadequacy (p=0.016) was found, and scabies shows a strong statistical association with overcrowding (p=0.025). Conclusion: The skin diseases involve every age strata of our population but it is fairly common in younger age group, women, and people who do not practice hygiene. Out-reach services for the rural and slum communities and health education will give good results on prevention of skin diseases. (author)

    Radiologically visible parenchymal changes (small opacities >= 1/0;ILO 1980 classification) were present in 20% of a sample of workers (N=174), employed for 20 years (median) in an asbestos cement plant. Exposure-response relationships were found, after controlling for age and smoking habits. In a sample of asbestos cement workers with symptoms and signs suggestive of pulmonary disease (N=33), increased lung density measured by x-ray computed tomography, and reduced static lung volumes and lung compliance was found. In a cohort of asbestos cement workers (N=1.929) with an estimated median exposure of 1.2 fibres/ml, the mortality from non-malignant respiratory disease was increased in comparison to a regional reference cohort (N=1.233). A two-to three-fold increase of non-malignant respiratory mortality was noted among workers employed for more than a decade in the asbestos cement plant, compared to cement workers (N=1.526), who in their turn did not experience and increased risk compared to the general population. In the cohorts of asbestos cement and cement workers, there was a tow-to three-fold increased incidence of cancer in the right part of the colon, compared to the general population as well as to external reference cohorts of other industrial workers (N=3.965) and fishermen (N=8.092). A causal relation with the exposure to mineral dust and fibres was supported by the findings of higher risk estimated in subgroups with high cumulated asbestos doses or longer duration of cement work. The incidence of cancer in the left part of the colon was not increased. Morbidity data, but not mortality data, disclosed the subsite-specific risk pattern. Both asbestos cement workers and cement workers has an increased incidence of rectal cancer, compared with the general population, and with the fishermen. The risk was, however, of the same magnitude among the other industrial workers. 181 refs

    Established risk factors for breast cancer explain breast cancer risk only partially. Organochlorines are considered to be a possible cause for hormone-dependent cancers. A hospital-based case-control study, the first from India, was conducted among 50 women undergoing surgery for breast disease to examine the association between organochlorine exposure and breast cancer risk. Blood, tumor, and surrounding adipose tissue of the breast were collected from the subjects with benign (control) and malignant breast (study) lesions and analyzed to determine organochlorine insecticides using a gas-liquid chromatograph equipped with an electron capture detector. The α, β, γ, and δ isomers of hexachlorocyclohexane (HCH), p,p'-dichlorodiphenyltrichloroethane (DDT), o,p'-DDT, p,p-dichlorodiphenyldichloroethylene, and p,p'-dichlorodiphenyldichloroethane were frequently detected in three specimens. Total HCH and total DDT levels were higher in the blood of the study group (25 cases) than in those of the controls (25 cases) with only γ-HCH being significantly different (P0.05). However, both total HCH and total DDT were higher in the tumor tissues of the controls than in those of the study group; γ-HCH was significantly different (P0.05). The level of total HCH (α-HCH was significantly different, P0.05) was higher in the breast adipose tissue of the study group, whereas total DDT was higher in the breast adipose tissue of the control group. The distribution of known confounders of breast cancer including age, body mass index, age at menarche and menopause, duration of breast feeding, and family history related to breast disease did not differ significantly between benign and malignant groups. This pilot study with limited statistical power does not support a positive association between exposure to organochlorines and risk of breast cancer but paves the way for a larger Indian study with greater statistical power encompassing different regions of the country to enable

    The main goal of our study was to confirm the usefulness of intra-operative parathyroid hormone (PTH) monitoring (ioPTH) when using minimally invasive techniques for treatment of sporadic Primary hyperparathyroidism (pHTP). Furthermore, we aimed to evaluate if ioPTH monitoring may help to predict the etiology of primary hyperparathyroidism, especially in malignant or multiglandular parathyroid disease. A retrospective review of 125 consecutive patients with pHPT who underwent parathyroidectomy between 2001 and 2016 at the Department of General Surgery was performed. For each patient, the specific preoperative work-up consisted of: high-resolution US of the neck by a skilled sonographer, sestamibi parathyroid scan, laryngoscopy, and serum measurement of PTH, serum calcium levels, and serum 25(OH)D levels. The study included 125 consecutive patients who underwent surgery for pHPT. At the histological examination, we registered 113 patients with simple adenomatous pathology (90,4%), 5 atypical adenomas (4%), 3 cases of parathyroid carcinoma (2,4%),, , and 4 histological exams of different nature (3,2%). Overall, 6 cases (4,8%) of multiglandular disease were found. We reported 10 cases (8%) of recurrent/persistent hyperparathyroidism: 1/10 in a patient affected by atypical adenoma, 9/10 in patients with benign pathology. Regarding these 10 cases, in three (30%) patients, ioPTH wasn't dosed (only frozen section (FS) exam was taken), in 5 cases (50%) ioPTH dropped more than 50% compared to basal value (false negative results), and in 2 (20%) cases, ioPTH did not drop >50% from the first samples taken, the extemporary exam had confirmed the presence of adenoma and the probable second hyperfunctioning adenoma was not found. IoPTH determinations ensure operative success of surgical resection in almost all hyperfunctioning tissue; in particular it is very important during minimally invasive parathyroidectomy, as it allows avoiding bilateral neck exploration. The use of io

    To date, no formal study has been published regarding how Colombian patients with skin disorders could be affected according to their perception of disease. To determine the impact in quality of life of skin diseases in a Colombian population. This multicenter study included patients with skin disease from almost the whole country. Individuals >18 years old; of any gender; with any skin disease and who signed informed consent, were included. We applied the Colombian validated version of the Skindex-29 instrument. A total of 1896 questionnaires had sufficient information for the analyses. No significant differences in sociodemographic characteristics of patients who returned the questionnaire incomplete vs. complete, were found. Participants mean age was 41.5 years. There were no statistical differences in men vs. women regarding the global (p=0.37), symptoms (p=0.71) and emotions (p=0.32) domains, whereas statistical differences were found in the function domain (p=0.04; Mann-Whitney U test). Psoriasis, contact dermatitis, atopic dermatitis, urticaria, hair disorders, Hansen's disease, scars, hyperhidrosis and genital human papillomavirus disease scored the highest. Skindex-29 score variability as a result of differences in the location of the skin lesions, their inflammatory or non-inflammatory nature, and the start of therapy. Even the most localized or asymptomatic skin lesion in our population leads to a disruption at some level of patient's wellness. This study adds well supported scientific data of the burden of skin diseases worldwide. Copyright © 2016 AEDV. Publicado por Elsevier España, S.L.U. All rights reserved.

    Pediatric skin disorders can affect children's self-esteem, relationships with caregivers and peers, and performance in school and activities. This review describes common pediatric congenital and acquired dermatologic disorders and the impact that these disorders can have on children's self-esteem. A review of current, English-language literature was conducted with use of the PubMed database. Search terms included atopic dermatitis, acne, infantile hemangiomas, port wine stains, congenital melanocytic nevi, hidradenitis suppurativa, and self-esteem. During infancy and toddlerhood, skin disorders such as infantile hemangiomas primarily affect the attachment between child and caregiver. School-aged children with port wine stains and atopic dermatitis report increased bullying, teasing, and social isolation. Acne and hidradenitis typically affect older children and teens and these conditions are associated with increased risks of depression and suicidal ideation. Effective management of these conditions has been shown to increase patients' self-esteem. Pediatric dermatologic disorders impact self-esteem throughout childhood. In addition to the surgical and medical management of these disorders, clinicians can also take an active role in the assessment and improvement of the psychosocial impact of these skin disorders.

    2017-07-01

    Full Text Available This review concerns five species of trees and palm trees that occur as dominant plants in different rainforest areas of the Amazon region. Due to their abundance, these species can be exploited as sustainable sources of botanical materials and include Carapa guianensis Aubl., family Meliaceae; Eperua falcata Aubl., family Fabaceae; Quassia amara L., family Simaroubaceae; and Attalea speciosa Mart. and Oenocarpus bataua Mart., family Arecaceae. For each species, the general features, major constituents, overall medicinal properties, detailed dermatological and skin care applications, and possible harmful effects have been considered. The major products include seed oils from A. speciosa and C. guianensis, fruit oil from O. bataua, and active compounds such as limonoids from C. guianensis, flavonoids from E. falcata, and quassinoids from Q. amara. The dermatologic and cosmetic applications of these plants are growing rapidly but are still widely based on empiric knowledge. Applications include skin rehydration and soothing; anti-inflammatory, antiage, and antiparasite effects; hair care; burn and wound healing; and the amelioration of rosacea and psoriasis conditions. Despite a limited knowledge about their constituents and properties, these species appear as promising sources of bioactive compounds for skin care and health applications. An improvement of knowledge about their properties will provide added value to the exploitation of these forest resources.

    According to the National Institutes of Health classification of chronic graft-versus-host disease (cGVHD), skin ulcers after allogeneic haematopoietic stem-cell transplantation (HSCT) are recorded as having the maximal severity score but published data are scarce. To describe skin ulcers related to cGVHD with an emphasis on clinical findings, associated morbidity, management and evolution. A multicentre retrospective analysis was carried out of patients with a diagnosis of cGVHD skin ulcers. All 25 patients included in the study had sclerotic skin cGVHD and 21 had lichenoid skin lesions associated with the sclerotic skin lesions. Thirteen patients had severe cGVHD without considering the skin, because of the involvement of an extracutaneous organ by cGVHD. The median time from HSCT to the onset of ulcers was 44 months. In addition to scleroderma, initial skin lesions at the site of ulcers were bullous erosive lichen in 21 patients and bullous erosive morphoea in four patients. Fifteen patients had an inaugural oedema. Ulcers were mostly bilateral with a predilection for the lower limbs. They were frequently colonized but few infections occurred. Four patients died during a median follow-up period of 55 months. Chronic graft-versus-host disease skin ulcers occur in patients with sclerodermatous skin cGVHD, are associated with severe cGVHD, often start with bullous lichenoid lesions or bullous morphoea and seem to cause more morbidity than mortality, given the low rate of mortality observed in our series of patients. © 2014 British Association of Dermatologists.

    Research highlights: {yields} Primary keratinocytes express the steroid enzymes required for cortisol synthesis. {yields} Normal primary human keratinocytes can synthesise cortisol. {yields} Steroidogenic regulators, StAR and MLN64, are expressed in normal epidermis. {yields} StAR expression is down regulated in eczema and psoriatic epidermis. -- Abstract: Cortisol-based therapy is one of the most potent anti-inflammatory treatments available for skin conditions including psoriasis and atopic dermatitis. Previous studies have investigated the steroidogenic capabilities of keratinocytes, though none have demonstrated that these skin cells, which form up to 90% of the epidermis are able to synthesise cortisol. Here we demonstrate that primary human keratinocytes (PHK) express all the elements required for cortisol steroidogenesis and metabolise pregnenolone through each intermediate steroid to cortisol. We show that normal epidermis and cultured PHK express each of the enzymes (CYP11A1, CYP17A1, 3{beta}HSD1, CYP21 and CYP11B1) that are required for cortisol synthesis. These enzymes were shown to be metabolically active for cortisol synthesis since radiometric conversion assays traced the metabolism of [7-{sup 3}H]-pregnenolone through each steroid intermediate to [7-{sup 3}H]-cortisol in cultured PHK. Trilostane (a 3{beta}HSD1 inhibitor) and ketoconazole (a CYP17A1 inhibitor) blocked the metabolism of both pregnenolone and progesterone. Finally, we show that normal skin expresses two cholesterol transporters, steroidogenic acute regulatory protein (StAR), regarded as the rate-determining protein for steroid synthesis, and metastatic lymph node 64 (MLN64) whose function has been linked to cholesterol transport in steroidogenesis. The expression of StAR and MLN64 was aberrant in two skin disorders, psoriasis and atopic dermatitis, that are commonly treated with cortisol, suggesting dysregulation of epidermal steroid synthesis in these patients.

    Full Text Available BACKGROUND: Dermatomyositis (DM is an autoimmune disease that mainly affects the skin, muscle, and lung. The pathogenesis of skin inflammation in DM is not well understood. METHODOLOGY AND FINDINGS: We analyzed genome-wide expression data in DM skin and compared them to those from healthy controls. We observed a robust upregulation of interferon (IFN-inducible genes in DM skin, as well as several other gene modules pertaining to inflammation, complement activation, and epidermal activation and differentiation. The interferon (IFN-inducible genes within the DM signature were present not only in DM and lupus, but also cutaneous herpes simplex-2 infection and to a lesser degree, psoriasis. This IFN signature was absent or weakly present in atopic dermatitis, allergic contact dermatitis, acne vulgaris, systemic sclerosis, and localized scleroderma/morphea. We observed that the IFN signature in DM skin appears to be more closely related to type I than type II IFN based on in vitro IFN stimulation expression signatures. However, quantitation of IFN mRNAs in DM skin shows that the majority of known type I IFNs, as well as IFN g, are overexpressed in DM skin. In addition, both IFN-beta and IFN-gamma (but not other type I IFN transcript levels were highly correlated with the degree of the in vivo IFN transcriptional response in DM skin. CONCLUSIONS AND SIGNIFICANCE: As in the blood and muscle, DM skin is characterized by an overwhelming presence of an IFN signature, although it is difficult to conclusively define this response as type I or type II. Understanding the significance of the IFN signature in this wide array of inflammatory diseases will be furthered by identification of the nature of the cells that both produce and respond to IFN, as well as which IFN subtype is biologically active in each diseased tissue.

    Full Text Available Catatonia is a syndrome characterized by mutism, immobility, negativism, stereotypy, mannerisms, echophenomena, perseveration and passive obedience. The underlying causes can be psychiatric or may be associated with general medical status or neurological diseases. Additionally catatonia has two subtypes as malignant and nonmalignant catatonia. Main symptoms of malignant catatonia are hyperthermia and autonomic symptoms such as tachycardia, tachypnea and hyperhidrosis. It is important to make the diagnosis as early as possible for an appropriate medical treatment. Clinicians should be aware of the fatal outcome of the disease.

    Previous studies have not showed consistent results for the level of expression of sodium/iodide symporter (NIS) in thyroid diseases, especially malignant tumor. We undertook this study to evaluate the distribution of NIS expression in malignant thyroid diseases and compare with that in benign thyoid disease. Total patients were 119 cases (Men 15, 48{+-}13 yrs). Total number of samples were 205 pieces. In malignant thyroid disease, there were 153 samples: 90 in papillary carcinoma, 4 in follicular carcinoma, 2 in medullary carcinoma and 57 in metastatic lymph node. In benign thyroid disease, there were 52 samples: 36 in goiter/cyst, 11 in thyroiditis and 5 in follicular adenoma. Using immunohistochemical methods, we probed 205 samples with monoclonal anti-NIS Ab. Grading of staining was scored as 0 (negative or absent), 1 (weakly positive), 2 (moderately positive) or 3 (strongly positive). Expression rate (ER) of NIS positivity in individual disease entity was expressed as percentage of total number divided by number in 2 plus 3 grade. ERs of malignant thyroid diseases were 63% in papillary carcinoma, 81% in metastatic lymph node, 71% in follicular carcinoma and 100% in medullary carcinoma. ERs of benign thyroid disease were 53% in goiter/cyst, 64% in thyroiditis and 40% in follicular adenoma. ER of benign thyroid deceases was higher than benign thyroid diseases (71% vs 54%). Grading of NIS expression in papillary carcinoma or goiter/cyst was heterogeneously distributed in considerable cases. Normal tissue also showed heterogeneous distribution or NIS expression, which was not correlated with that of primary lesion. In papillary thyroid carcinoma, distribution of NIS expression was heterogeneous and increased, and not different compared with that of benign thyroid disease.

    In 100 dogs with 4 inflammatory dermatologic diseases, buffy coat preparations from EDTA-treated blood samples were examined cytologically. Fifty-four dogs had atopy, 26 had flea-bite hypersensitivity, 17 had sarcoptic mange, and 3 had food allergy. Twenty-eight dogs had 2 or more concurrent skin diseases; most of these had secondary pyoderma. Dogs did not have mast cell tumors. Thirteen samples contained 1 or more mast cells/4 slides reviewed. This study revealed that dogs with inflammatory skin diseases can have a few to many mast cells evident on cytologic examination of buffy coat preparations.

    2010-02-01

    Vibrio anguillarum causes a fatal haemorrhagic septicaemia in marine fish. During initial stages of infection, host surfaces are colonized; however, few virulence factors required for colonization of the host are identified. In this study, in vivo bioluminescent imaging was used to analyse directly the colonization of the whole rainbow trout animal by V. anguillarum. The wild type rapidly colonized both the skin and the intestines by 24 h; however, the bacterial numbers on the skin were significantly higher than in the intestines indicating that skin colonization may be important for disease to occur. Mutants defective for the anguibactin iron uptake system, exopolysaccharide transport, or Hfq, an RNA chaperone, were attenuated for virulence, did not colonize the skin, and penetrated skin mucus less efficiently than the wild type. These mutants, however, did colonize the intestines and were as resistant to 2% bile salts as is the wild type. Moreover, exopolysaccharide mutants were significantly more sensitive to lysozyme and antimicrobial peptides, while the Hfq and anguibactin mutants were sensitive to lysozyme compared with the wild type. Vibrio anguillarum encodes several mechanisms to protect against antimicrobial components of skin mucus enabling an amazingly abundant growth on the skin enhancing its disease opportunities. © 2010 Society for Applied Microbiology and Blackwell Publishing Ltd.

    The aim of this study was to identify an alternative temporary skin marker that could be used to mark the skin of the breast prior to surgery, providing the surgeon with longer lasting accurate guidance to the location of the patient's breast lesion. Materials and methods: The upper quadrant of the breast was marked on all participants (n = 20) with a code in both henna and the conventional skin marker and photographic images were taken every 3 days for 2 weeks to assess the degree of fade. In addition a questionnaire (n = 136) surveyed current clinical practice amongst other breast services in the region. Results: This study found that henna lasted on average 6 days longer on study participants than the original skin marker used. The skin marker lasted on average 3 days whereas henna lasted on average 9 days, in addition participants who showered and used body wash/soap found that the henna skin marker lasted longer on the skin than participants' who bathed and used exfoliate. The survey revealed comments on current products such as sterility, ease of use and quick to apply but interestingly only 9% considered their current marker to be clearly visible. Conclusion: Henna is an effective temporary skin marker that could be used to mark the breast of patients with breast disease pre-operatively. It is cost effective when purchased in bulk, is more easily applied over ultrasound gel and has the potential to reduce infection prior to surgery.

    This Guideline is an official statement of the European Society of Gastrointestinal Endoscopy (ESGE), endorsed by the European Society for Radiotherapy and Oncology (ESTRO), the European Society of Digestive Endoscopy (ESDO), and the European Society for Clinical Nutrition and Metabolism (ESPEN). The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system was adopted to define the strength of recommendations and the quality of evidence. Main recommendations for malignant disease 1 ESGE recommends placement of partially or fully covered self-expandable metal stents (SEMSs) for palliative treatment of malignant dysphagia over laser therapy, photodynamic therapy, and esophageal bypass (strong recommendation, high quality evidence). 2 For patients with longer life expectancy, ESGE recommends brachytherapy as a valid alternative or in addition to stenting in esophageal cancer patients with malignant dysphagia. Brachytherapy may provide a survival advantage and possibly a better quality of life compared to SEMS placement alone. (Strong recommendation, high quality evidence.) 3 ESGE recommends esophageal SEMS placement as the preferred treatment for sealing malignant tracheoesophageal or bronchoesophageal fistula (strong recommendation, low quality evidence). 4 ESGE does not recommend the use of concurrent external radiotherapy and esophageal stent treatment. SEMS placement is also not recommended as a bridge to surgery or prior to preoperative chemoradiotherapy. It is associated with a high incidence of adverse events and alternative satisfactory options such as placement of a feeding tube are available. (Strong recommendation, low quality evidence.) Main recommendations for benign disease 1 ESGE recommends against the use of self-expandable stents (SEMSs) as first-line therapy for the management of benign esophageal strictures because of the potential for adverse events, the availability of alternative therapies, and costs (strong

    Deep brain stimulation (DBS) has been recognized as an efficacious treatment for movement disorders. Its beneficial effects however may be lost due to skin complications such as erosions or infections over the implanted foreign material. We sought to document skin complications in the entire Parkinson's disease patient population who received a DBS system at the Marburg/Kassel implantation centre since the start of our DBS program in January 2002 to analyze frequency, time course, and possible risk factors. We investigated 85 consecutive patients with Parkinson's disease (PD) from a single center/single surgeon DBS series for the occurrence of skin complications and analyzed localization, time course, and possible risk factors. Mean follow-up was 3 years (range 1-7 years). In total, 21/85 patients (24.7%) suffered a total of 30 single skin complications. Sixty percent of all incidents occurred within the first post-operative year. Forty percent of all incidents occurred later than the first year following primary implantation. Complications involved the burr hole cap in 37%, the course of the cables in 33%, and the impulse generator (IPG) site in 30%. Six of 21 patients suffered recurring skin complications. Eight patients permanently lost their DBS system. Factor analysis for age, gender, disease duration, disease severity, the incidence of hypertension or diabetes as well as a 2-day period with externalized electrodes for continuous test stimulation did not have any statistically significant impact on skin complications. We conclude that (1) PD patients have a risk for skin complications after DBS as long as the system remains in situ and (2) there are at present no identifiable risk factors for skin complications after DBS, other than PD itself.

    To compare the multidetector CT (MDCT) features of malignant pleural mesothelioma (MPM) and metastatic pleural disease (MPD). The authors reviewed the MDCT images of 167 patients, 103 patients with MPM and 64 patients with MPD. All 167 cases were pathologically confirmed by sonography-guided needle biopsy of pleura, thoracoscopic pleural biopsy, or open thoracotomy. CT features were evaluated with respect to pleural effusion, pleural thickening, invasion of other organs, lung abnormality, lymphadenopathy, mediastinal shifting, thoracic volume decrease, asbestosis, and the presence of pleural plaque. Pleural thickening was the most common CT finding in MPM (96.1%) and MPD (93.8%). Circumferential pleural thickening (31.1% vs. 10.9%, odds ratio [OR] 3.670), thickening of fissural pleura (83.5% vs. 67.2%, OR 2.471), thickening of diaphragmatic pleura (90.3% vs. 73.4%, OR 3.364), pleural mass (38.8% vs. 23.4%, OR 2.074), pericardial involvement (56.3% vs. 20.3%, OR 5.056), and pleural plaque (66.0% vs. 21.9%, OR 6.939) were more frequently seen in MPM than in MPD. On the other hand, nodular pleural thickening (59.2% vs. 76.6%, OR 0.445), hilar lymph node metastasis (5.8% vs. 20.3%, OR 0.243), mediastinal lymph node metastasis (10.7% vs. 37.5%, OR 0.199), and hematogenous lung metastasis (9.7% vs. 29.2%, OR 0.261) were less frequent in MPM than in MPD. When we analyzed MPD from extrathoracic malignancy (EMPD) separately and compared them to MPM, circumferential pleural thickening, thickening of interlobar fissure, pericardial involvement and presence of pleural plaque were significant findings indicating MPM than EMPD. MPM had significantly lower occurrence of hematogenous lung metastasis, as compared with EMPD. Awareness of frequent and infrequent CT findings could aid in distinguishing MPM from MPD.

    Objective The Pediatric Rheumatology International Trials Organisation (PRINTO) recently published criteria for classification of patients with juvenile dermatomyositis (DM) as having clinically inactive disease. The criteria require that at least 3 of 4 conditions be met, i.e., creatine kinase level ≤150 units/liter, Childhood Myositis Assessment Scale score ≥48, Manual Muscle Testing in 8 muscles score ≥78, and physician's global assessment of overall disease activity (PGA) ≤0.2. The present study was undertaken to test these criteria in a UK cohort of patients with juvenile DM. Methods We assessed 1,114 patient visits for the 4 items in the PRINTO criteria for clinically inactive disease. Each visit was analyzed to determine whether skin disease was present. The Disease Activity Score (DAS) for juvenile DM was determined in 59 patients. Results At 307 of the 1,114 visits, clinically inactive disease was achieved based on the 3 muscle criteria (but with a PGA of >0.2); rash was present at 65.8% of these visits and nailfold capillary abnormalities at 35.2%. When PGA ≤0.2 was one of the 3 criteria that were met, the frequency of skin signs was significantly lower (rash in 23.1% and nailfold capillary abnormalities in 8.7%). If PGA was considered an essential criterion for clinically inactive disease (P‐CID), patients with active skin disease were less likely to be categorized as having clinically inactive disease (a median DAS skin score of 0 [of a possible maximum of 9] in visits where the PGA was ≤0.2, versus a median DAS skin score of 4 in patients meeting the 3 muscle criteria [with a PGA of >0.2]; P < 0.001). Use of the P‐CID led to improvements in the positive predictive value and the positive likelihood ratio (85.4% and 11.0, respectively, compared to 72.9% and 5.1 with the current criteria). Conclusion There was a high frequency of skin disease among patients with juvenile DM who did not meet the PGA criterion for inactive disease but met

    Puffy skin disease (PSD) is a disease that causes skin pathology in rainbow trout, Oncorhynchus mykiss (Walbaum). Incidence of PSD in UK fish farms and fisheries has increased sharply in the last decade, with growing concern from both industry sectors. This paper provides the first comprehensive case definition of PSD, combining clinical and pathological observations of diseased rainbow trout from both fish farms and fisheries. The defining features of PSD, as summarized in the case definition, were focal lateral flank skin lesions that appeared as cutaneous swelling with pigment loss and petechiae. These were associated with lethargy, poor body condition, inappetance and low level mortality. Epidermal hyperplasia and spongiosis, oedema of the dermis stratum spongiosum and a mild diffuse inflammatory cellularity were typical in histopathology of skin. A specific pathogen or aetiology was not identified. Prevalence and severity of skin lesions was greatest during late summer and autumn, with the highest prevalence being 95%. Atypical lesions seen in winter and spring were suggestive of clinical resolution. PSD holds important implications for both trout aquaculture and still water trout fisheries. This case definition will aid future diagnosis, help avoid confusion with other skin conditions and promote prompt and consistent reporting. © 2014 John Wiley & Sons Ltd.

    In order to study clinical significance of serum prostate-specific antigen (PSA), free prostate specific antigen (PSA), f/tPSA and six sex hormones in prostate diseases, the serum levels of PSA, fPSA, f/tPSA, T, P, E 2 , PRL, LH and FSH in 72 cases of hyperplasia of prostate patients and 40 patients with prostate cancer were determined by RIA. The results showed that the serum levels of T, E 2 , PRL, LH, FSH in the BPH Group were significantly lower than those of in Pca group, the serum level of P in Pca group were significantly lower than those in BPH group; the levels of fPSA and f/tPSA ratio in BPH Group were significantly higher than those in Pca group. The results suggest that benign and malignant prostate disease (BPH and Pca) was related with the hormone imbalance. The serum total PSA and fPSA can be regarded as important indicators in the diagnosis of BPH and Pea. The combined determination of PSA, fPSA and f/tPSA may improve the diagnostic accuracy of Pca.

    Distal pancreatectomy is the standard curative treatment for symptomatic benign, premalignant, and malignant disease of the pancreatic body and tail. The most obvious benefits of a laparoscopic approach to distal pancreatectomy include earlier recovery and shorter hospital stay. Spleen-preserving distal pancreatectomy should be attempted in case of benign disease. Spleen preservation can be achieved preferably by preserving the splenic vessels (Kimura technique), but also by resecting the splenic vessels and maintaining vascularity through the short gastric vessels and left gastroepiploic artery (Warshaw technique). Several studies have suggested a higher rate of spleen preservation with laparoscopy. The radical antegrade modular pancreatosplenectomy has become mainstay for treating pancreatic cancer and can be performed laparoscopically as well. Evidence on the feasibility and safety of laparoscopic distal pancreatectomy for cancer is scarce. Despite the obvious advantages of laparoscopic surgery, postoperative morbidity remains relatively high, mainly because of the high incidence of pancreatic fistula. For decades, surgeons have tried to prevent these fistulas but to date no strategy has been confirmed to be effective in 2 consecutive randomized studies. Pragmatic multicenter studies focusing on technical aspects of laparoscopic distal pancreatectomy are lacking and should be encouraged. PMID:26240565

    A shared genetic susceptibility between cutaneous malignant melanoma (CMM) and Parkinson's disease (PD) has been suggested. We investigated this by assessing the contribution of rare variants in genes involved in CMM to PD risk. We studied rare variation across 29 CMM risk genes using high-quality genotype data in 6875 PD cases and 6065 controls and sought to replicate findings using whole-exome sequencing data from a second independent cohort totaling 1255 PD cases and 473 controls. No statistically significant enrichment of rare variants across all genes, per gene, or for any individual variant was detected in either cohort. There were nonsignificant trends toward different carrier frequencies between PD cases and controls, under different inheritance models, in the following CMM risk genes: BAP1, DCC, ERBB4, KIT, MAPK2, MITF, PTEN, and TP53. The very rare TYR p.V275F variant, which is a pathogenic allele for recessive albinism, was more common in PD cases than controls in 3 independent cohorts. Tyrosinase, encoded by TYR, is the rate-limiting enzyme for the production of neuromelanin, and has a role in the production of dopamine. These results suggest a possible role for another gene in the dopamine-biosynthetic pathway in susceptibility to neurodegenerative Parkinsonism, but further studies in larger PD cohorts are needed to accurately determine the role of these genes/variants in disease pathogenesis.

  19. Commercial Essential Oils as Potential Antimicrobials to Treat Skin Diseases

    2017-01-01

    Essential oils are one of the most notorious natural products used for medical purposes. Combined with their popular use in dermatology, their availability, and the development of antimicrobial resistance, commercial essential oils are often an option for therapy. At least 90 essential oils can be identified as being recommended for dermatological use, with at least 1500 combinations. This review explores the fundamental knowledge available on the antimicrobial properties against pathogens responsible for dermatological infections and compares the scientific evidence to what is recommended for use in common layman's literature. Also included is a review of combinations with other essential oils and antimicrobials. The minimum inhibitory concentration dilution method is the preferred means of determining antimicrobial activity. While dermatological skin pathogens such as Staphylococcus aureus have been well studied, other pathogens such as Streptococcus pyogenes, Propionibacterium acnes, Haemophilus influenzae, and Brevibacterium species have been sorely neglected. Combination studies incorporating oil blends, as well as interactions with conventional antimicrobials, have shown that mostly synergy is reported. Very few viral studies of relevance to the skin have been made. Encouragement is made for further research into essential oil combinations with other essential oils, antimicrobials, and carrier oils.

    The systemic (extrapulmonary) effects and comorbidities of chronic obstructive pulmonary disease (COPD) contribute substantially to its burden. The supposed link between COPD and its systemic effects on distal organs could be due to the low-grade systemic inflammation. The aim of this study was to investigate whether the systemic inflammation may influence the skin condition in COPD patients. Forty patients with confirmed diagnosis of COPD and a control group consisting of 30 healthy smokers and 20 healthy never-smokers were studied. Transepidermal water loss, stratum corneum hydration, skin sebum content, melanin index, erythema index, and skin temperature were measured with worldwide-acknowledged biophysical measuring methods at the volar forearm of all participants using a multifunctional skin physiology monitor. Biomarkers of systemic inflammation, including high-sensitivity C-reactive protein (hsCRP), interleukin-6 (IL-6), and tumor necrosis factor α (TNF-α), were measured in serum using commercially available enzyme-linked immunosorbent assays. There were significant differences between COPD patients and healthy never-smokers in skin temperature, melanin index, sebum content, and hydration level ( P skin measured. The mean levels of hsCRP and IL-6 in serum were significantly higher in COPD patients and healthy smokers in comparison with healthy never-smokers. There were significant correlations between skin temperature and serum hsCRP ( R =0.40; P =0.02) as well as skin temperature and serum IL-6 ( R =0.49; P =0.005) in smokers. Stratum corneum hydration correlated significantly with serum TNF-α ( R =0.37; P =0.01) in COPD patients. Differences noted in several skin biophysical properties and biomarkers of systemic inflammation between COPD patients, smokers, and healthy never-smokers may suggest a possible link between smoking-driven, low-grade systemic inflammation, and the overall skin condition.

    Cosmetologists frequently develop occupational skin disease related to workplace exposures. The purpose of this study was to evaluate an educational intervention to increase cosmetology students' occupational skin disease knowledge and use of preventive practices. A quasi-experimental design was used to evaluate students' knowledge, behaviors, intentions, expectancies, and expectations. A 20-minute verbal presentation and printed two-page educational handout were provided for participants. Statistically significant increases in knowledge, frequency of glove use, and frequency of moisturizer use were found, but the frequency of handwashing did not increase. In addition, the Behavioral Strategies subscale, the Intention subscale, and the Expectancies subscale showed statistically significant improvements. The results of this study suggest an educational intervention can increase cosmetology students' knowledge of occupational skin diseases and their use of preventive strategies.

    2017-04-01

    Helicobacter pylori, one of the most frequently observed bacterium in the human intestinal flora, has been widely studied since Marshall and Warren documented a link between the presence of H. pylori in the gastrointestinal tract and gastritis and gastric ulcers. Interestingly, H. pylori has also been found in several other epithelial tissues, including the eyes, ears, nose and skin that may have direct or indirect effects on host physiology and may contribute to extragastric diseases, e.g. chronic skin diseases. More recently, it has been shown that H. pylori cytotoxin CagA expression induces cellular senescence of human gastric nonpolarized epithelial cells that may lead to gastrointestinal disorders and systemic inflammation. Here, we hypothesize that also chronic skin diseases may be promoted by stress-induced premature senescence (SIPS) of skin cells, namely fibroblasts and keratinocytes, stimulated with H. pylori cytotoxins. Future studies involving cell culture models and clinical specimens are needed to verify the involvement of H. pylori in SIPS-based chronic skin diseases.

    The aim of the present study was to determine the spectrum of skin diseases seen among adult obese patients referred to Farwaniya Hospital. A total of 437 overweight/obese subjects (200 men and 237 women) aged 18-74 years were enrolled in the study, which was conducted from October 2008 to November 2009. Demographic details such as age, sex, occupation, personal and family history of diabetes mellitus, hypertension, and obesity were recorded. A thorough examination was performed by an experienced dermatologist (N.A.M.). Blood investigations such as complete blood count, fasting and postprandial blood sugar levels, liver function tests, kidney function tests, lipid profile, and thyroid function tests were done for all patients in addition to hormonal assay and abdominal sonar to exclude polycystic ovary disease for indicated patients. Common skin diseases found among these patients were plantar hyperkeratosis: n = 197; acanthosis nigricans: n = 144; skin tags: n = 131; striae cutis distensae: n = 102; intertrigo: n = 97; acne vulgaris: n = 94. Diabetes mellitus was diagnosed in 87 patients, polycystic ovary syndrome/hyperandrogenism in 74 female patients, and hyperlipidemia in 209 patients. This study shows that certain dermatoses such as plantar hyperkeratosis, acanthosis nigricans, skin tags, striae cutis distensae, and intertrigo are more common among obese persons. Some, such as plantar hyperkeratosis, could serve as markers of obesity and its severity, while the presence of acanthosis nigricans and skin tags may point to underlying internal disease such as diabetes and polycystic ovary syndrome.

    Based on the observation that the parasite Onchocerca volvulus selectively absorbs vitamin A from the host, and the known toxicity of vitamin A in higher concentration, it was hypothesized that dying microfilariae (mf) release their stores of vitamin A (retinoids) into the host circulation in toxic concentrations, inducing the signs and symptoms of onchocerciasis. We conducted a pilot study to test the hypothesis in Songea communities in Southern Tanzania, where mass drug administration with ivermectin had not been implemented by the time of the survey. The specific aim was to evaluate the correlation between the diagnosis of onchocerciasis and increased levels of retinoic acid at infection sites. The analysis was performed by determining copy numbers of a genome of O volvulus present in skin snip samples of persons with onchocerciacis, and correlating these numbers with expression levels of retinoic acid receptor-α (RAR-α), which is inducible by retinoic acid. Total DNA and RNA were extracted from each of 25 mf-positive and 25 mf-negative skin samples and evaluated using quantitative polymerase chain reaction with appropriate negative controls. Analysis of the samples, adjusted with glyceraldehyde 3-phosphate dehydrogenase gene levels, revealed that most samples with detectable RAR-α transcripts had higher levels of RAR-α expression than the assay control. However, the quality and number of samples were insufficient for statistical analysis. Fold data on the expression levels of both O volvulus DNA and RAR RNA suggested a possible trend toward higher relative RAR-α expression in samples with higher levels of O volvulus DNA ( r 2  = 0.25, P  = .079). Evidence of a contribution of vitamin A to the pathology of onchocerciasis thus remains elusive. Future studies on the role of retinoids in onchocerciasis will require larger groups of participants as well as careful monitoring of the cold chain and tissue storage procedures in view of the sensitivity of

    Diffuse skin thickening of the breast is produced by lymphedema usually secondary to obstruction of the axillary lymphatics. On physical examination, the affected breast is, due to increased fluid content, larger, heavier, and of higher overall density. Mammography reveals an increased coarse reticular pattern. Thickening of the skin can have many causes. It may be a result of tumor invasion or a tumor in the dermal lymphatics ; or because of lymphatic congestion through obstruction of lymphatic drainage within the breast, in the axilla, or centrally in the mediastinum. Further causes may be congestive heart failure, benign inflammation, primary skin processes such as psoriasis, or systemic diseases which involve the skin. Mammographic appearance is known to be nonspecific. Ultrasound can demonstrate skin thickening directly, but despite some reports suggesting that the cause of skin thickening can be inferred from the results of ultrasound, this is not usually of practical importance. The purpose of this study is to review the causes of skin thickening of the breast and to use mammography and US to differentiate the causes.

    Host defense peptides/proteins (HDPs), also known as antimicrobial peptides/proteins (AMPs), are key molecules in the cutaneous innate immune system. AMPs/HDPs historically exhibit broad-spectrum killing activity against bacteria, enveloped viruses, fungi and several parasites. Recently, AMPs/HDPs were shown to have important biological functions, including inducing cell proliferation, migration and differentiation; regulating inflammatory responses; controlling the production of various cytokines/chemokines; promoting wound healing; and improving skin barrier function. Despite the fact that AMPs/HDPs protect our body, several studies have hypothesized that these molecules actively contribute to the pathogenesis of various skin diseases. For example, AMPs/HDPs play crucial roles in the pathological processes of psoriasis, atopic dermatitis, rosacea, acne vulgaris, systemic lupus erythematosus and systemic sclerosis. Thus, AMPs/HDPs may be a double-edged sword, promoting cutaneous immunity while simultaneously initiating the pathogenesis of some skin disorders. This review will describe the most common skin-derived AMPs/HDPs (defensins, cathelicidins, S100 proteins, ribonucleases and dermcidin) and discuss the biology and both the positive and negative aspects of these AMPs/HDPs in skin inflammatory/infectious diseases. Understanding the regulation, functions and mechanisms of AMPs/HDPs may offer new therapeutic opportunities in the treatment of various skin disorders. © 2017 John Wiley & Sons A/S.

    Dermatologic manifestations of inflammatory bowel disease (IBD) are common, and certain IBD medications increase the risk of skin cancer. To define the rates of care and factors associated with dermatologic utilization with a focus on skin cancer screening. We utilized a prospective, natural history IBD research registry to evaluate all outpatient healthcare encounters from 2010 to 2016. Gastrointestinal, dermatologic and primary care visits per individual were identified. We calculated the proportion of patients obtaining care, categorized primary indications for dermatologic visits, determined the incidence of melanoma and non-melanoma skin cancers, and used logistic regression to determine factors associated with dermatology utilization. Of the 2127 IBD patients included, 452 (21.3%) utilized dermatology over the study period, and 55 (2.6%) had a total body skin examination at least once. The 452 patients incurred 1633 dermatology clinic visits, 278 dermatologic procedures, and 1108 dermatology telephone encounters. The most frequent indication was contact dermatitis or dermatitis. Factors associated with dermatology use were family history of skin cancer, employment, systemic steroids, longer disease duration, emergency room use, and the number of IBD-related clinic visits. Between 8.3 and 11% of IBD patients recommended for skin cancer screening visited dermatology each year, and the resulting incidence of non-melanoma skin cancer was 35.4/10,000 [95% CI 23.3-51.5] and melanoma was 6.56/10,000 [95% CI 2.1-15.3]. Less than one in ten IBD patients obtain dermatologic care. Given the increased risk of skin cancers among IBD patients, an emphasis on education, prevention, and screening merits attention.

    The records of 1329 patients with Hodgkin's disease admitted from 1965 to 1982 were analyzed to assess the relative frequency of second neoplasms. Within a median follow-up of 9.5 years, a total of 68 new cancers were documented. Nineteen cases of acute nonlymphocytic leukemia, 6 cases of non-Hodgkin's lymphomas, and 43 cases with different types of solid tumors were identified. The overall risk of non-Hodgkin's lymphoma was 1.3% +/- 0.6% and of solid tumors was 8.3% +/- 1.5% when basal cell carcinomas were included and 6.7% +/- 1.4% when basal cell carcinomas were excluded. No cases of leukemia were documented in patients treated with radiation therapy only. The 12-year estimate of leukemia by treatment was as follows: chemotherapy only 1.4% +/- 2.3%; radiation plus MOPP (mechlorethamine, vincristine, procarbazine, and prednisone) 10.2% +/- 5.2%; radiation plus ABVD (Adriamycin, bleomycin, vinblastine, and dacarbazine) 0; and radiation plus other drug regimens 4.8% +/- 1.6%. The risk of leukemia was particularly high (15.5% +/- 7.4%) in patients who received salvage MOPP after radiation failure. A positive association was also noted between increasing age and risk of second malignancies, especially leukemia. The incidence of second neoplasms can be markedly decreased by deleting from potentially curative therapy certain drugs such as alkylating agents, procarbazine, and nitrosourea derivatives

    To assess the prevalence and morphologic characterization of pulmonary nodules in children on a chest computed tomography (CT). Two hundred and fifty-nine trauma chest CTs in children aged 0-18 years were retrospectively reviewed by two radiologists, each with more than 10 years of experience. Images were acquired on a 64-row CT. Pulmonary lobes with trauma affections such as contusion or haemorrhage were excluded. All pulmonary nodules were evaluated for distance from the pleural surface, location, calcification and size on axial slices. A total of 1,190/1,295 (92 %) pulmonary lobes without traumatic injury were included in this study. In 86 of 259 (33 %) patients, 131 pulmonary nodules were detected. Number of nodules per patient ranged from 1 to 4. Calcifications were seen in 19 % (25) of all nodules. Diameters ranged from 1 to 5 mm. 59 % (77) were located in the lower lobes, 9 % (12) in the middle lobe and 32 % (42) in the upper lobes. 84 % of the non-calcified nodules >2 mm showed a slightly angular or triangular (mostly pleural nodes) shape. Pulmonary nodules smaller than 5 mm can be detected frequently in children without malignant disease and are predominantly located in the lower lobes. (orig.)

    The aim was to determine the efficacy, safety, and long-term clinical and functional results of coloanal anastomosis in patients with complicated benign and malignant rectal disease. Twenty-nine patients underwent coloanal or colopouch-anal anastomosis for either carcinoma of the rectum not technically amenable to conventional low anterior resection, severe radiation injury, large benign lower third tumors, or complications of previous operations. The mean age of the patients was 61 years and 82% were men. A diverting colostomy was constructed in 55% of the patients. The mean (+/- SEM) length of follow-up was 20 +/- 3 months. There was no operative mortality. Transient urinary retention, however, occurred in 40%, anastomotic stricture in 28%, and anastomotic leakage in 3.4%. Four patients (14%) could not have intestinal continuity restored and therefore were considered failures. The stool frequency for all remaining patients (N = 25) was 3 +/- 1 per day (mean +/- SEM) and did not vary with age, sex, or indication for operation. Complete continence was achieved by 84% of patients, but no patient was incapacitated by poor bowel function. In patients in whom a conventional colorectostomy is impractical or unwise, coloanal anastomosis is a safe and efficacious alternative operation that preserves anal continence.

    This study aimed to evaluate concurrently detected thyroid pathologies in the patients who underwent surgery for primary hyperparathyroidism (PHPT). In this study, we retrospectively analyzed the files of the patients who underwent surgery for PHPT between 2012 and 2015. Pre- and post-operative laboratory examination results and preoperative radiological and nuclear medicine findings of the patients were retrospectively recorded. A total number of 41 patients with PHPT were divided into two groups as the Group 1 with PHPT and benign thyroid pathology (21 patients) and the Group 2 with PHPT and malignant thyroid pathology (20 patients). In Group 1, 18 and 3 of 21 patients were females and males, respectively. Group 2 included 15 male and 5 female patients. The mean age of the patients was found to be 55.6 and 53.9 years in Group 1 and Group 2, respectively. Both groups were matched for age and gender. In terms of thyroid pathology, 20 of 41 patients (48.7%) who underwent total thyroidectomy for PHPT were found to have thyroid papillary carcinoma while benign pathologic conditions were detected in 21 (51.3%) individuals. Cooccurrence of thyroid diseases and PHPT is common. Therefore, all the patients should preoperatively be evaluated for the presence of thyroid pathology to determine the technique of parathyroid surgery.

    The biopsy of the first tumor-draining lymph node (sentinel node) is bound to become the procedure of choice in regional staging of skin melanoma patients. In our department, we do successively: lymphoscintigraphy; identification of sentinel node by γ probe before surgery; identification during surgery of sentinel node with γ probe. During those different steps, the technologist has an important role. The different steps of the technologist's work are: Preparation of radiopharmaceutical Tc 99m Nanocolloides (Nanocis Cis Bio Int); Control of radio chemical purity(RCP) by thin-layer chromatography (TLC); Programming of acquisition protocol on the γ camera; Acquisition of dynamic and static images; Identification percutaneous of the sentinel node with the γ probe and Co 57 pencil; Processing of scintigraphic images; At least identification with surgeon of the sentinel node. After excision of the lymph node, we have to verify the disappearing of radioactivity. Those steps will be illustrated by different clinical cases. Conclusion: Sentinel node identification is: New useful technique for patient: not very much invasive; screening of patients with high risk factors; great parameters of prognosis; Interest for technologist: narrow collaboration with nuclearist and surgeon; psychological role close to the patient; various competency of technologist; diagnostic and therapeutic participations

    Research has indicated that the rs12203592 and rs872071 interferon regulatory factor 4 (IRF4) gene polymorphisms correlate with the risk of cancer, especially skin cancer and haematological malignancies, but the results remain controversial. To understand better the effects of these two polymorphisms on skin cancer and haematological malignancies susceptibility, a cumulative meta-analysis was performed. We conducted a search using the PubMed and Web of Science databases for relevant case-control studies published before April 2014. Summary odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were estimated using fixed- or random-effects models where appropriate. Heterogeneity test, publication bias test, and sensitivity analysis were also performed. In total, 11 articles comprised of 19 case–control studies were identified; five focused on the rs12203592 polymorphism with 7,992 cases and 8,849 controls, and six were on the rs872071 polymorphism with 3108 cases and 8300 controls. As for rs12203592, a significant correlation with overall skin cancer and haematological malignancies risk was found with the homozygote comparison model (OR = 1.566, 95% CI 1.087-2.256) and recessive model (OR = 1.526, 95% CI 1.107-2.104). For rs872071, a significantly elevated haematological malignancies risk was observed in all genetic models (homozygote comparison: OR = 1.805, 95% CI 1.402-2.323; heterozygote comparison: OR = 1.427, 95% CI 1.203-1.692; dominant: OR = 1.556, 95% CI 1.281-1.891; recessive: OR = 1.432, 95% CI 1.293-1.587; additive: OR = 1.349, 95% CI 1.201-1.515). Similarly, increased skin cancer and haematological malignancies risk was also identified after stratification of the SNP data by cancer type, ethnicity and source of controls for both polymorphisms. Our meta-analysis indicated that the rs12203592 and rs872071 IRF4 gene polymorphisms are associated with individual susceptibility to skin cancer and haematological malignancies. Moreover, the effect

    Photodynamic therapy (PDT) uses photosensitizers (PS) that are excited with light to generate ROS in the presence of oxygen for treating various diseases. PS also has the potential use as photodynamic insecticides (PDI) and for light-inactivation of Leishmania for photodynamic vaccination (PDV). PDT-inactivated Leishmania are non-viable, but remain immunologically competent as whole-cell vaccines against leishmaniasis, and as a universal carrier for delivery of add-on vaccines against other infectious and malignant diseases. We have screened novel PS, including Zn- and Si-phthalocyanines (PC) for differential PDT activities against Leishmania, insect and mammalian cells in vitro to assess their PDI and PDV potential. Here, Zn-PC were conjugated with various functional groups. The conjugates were examined for uptake by cells as a prerequisite for their susceptibility to light-inactivation. PDT sensitivity was found to vary with cell types and PS used. PDI potential of several PS was demonstrated by their mosquito larvicidal PDT activities in vitro. PDT-inactivated Leishmania were stored frozen for PDV in several ongoing studies: [1] Open label trial with 20 sick dogs for immunotherapy of canine leishmaniasis after chemotherapy in Naples, Italy. Clinical follow-up for >3 years indicate that the PDV prolongs their survival; [2] PDV of murine models with a human lung cancer vaccine showed dramatic tumor suppression; [3] Open label trial of multiple PDV via compassionate access to 4 advanced cancer patients showed no clinically adverse effects. Two subjects remain alive. Genetic modifications of Leishmania are underway to further enhance their safety and efficacy for PDV by installation of activable mechanisms for self-destruction and spontaneous light-emission.

    Optical microspectroscopic tools reveal great potential for dermatologic diagnostics in the clinical day-to-day routine. To enhance the diagnostic value of individual nonlinear optical imaging modalities such as coherent anti-Stokes Raman scattering (CARS), second harmonic generation (SHG) or two-photon excited fluorescence (TPF), the approach of multimodal imaging has recently been developed. Here, we present an application of nonlinear optical multimodal imaging with Raman-scattering microscopy to study sizable human-tissue cross-sections. The samples investigated contain both healthy tissue and various skin tumors. This contribution details the rich information content, which can be obtained from the multimodal approach: While CARS microscopy, which - in contrast to spontaneous Raman-scattering microscopy - is not hampered by single-photon excited fluorescence, is used to monitor the lipid and protein distribution in the samples, SHG imaging selectively highlights the distribution of collagen structures within the tissue. This is due to the fact, that SHG is only generated in structures which lack inversion geometry. Finally, TPF reveals the distribution of autofluorophores in tissue. The combination of these techniques, i.e. multimodal imaging, allows for recording chemical images of large area samples and is - as this contribution will highlight - of high clinically diagnostic value.

    Objective: To study the clinical significance of perioperative changes of serum IL-10 level in patients with benign and malignant pulmonary diseases. Methods: Serum IL-10 levels in patients with benign (n=17) and malignant (n=25) pulmonary diseases were measured before and 1, 3, 7, 14 days after operation with RIA. Values in 82 controls were also taken. Results: The preoperative levels of serum IL-10 in patients with lung cancer were significantly higher than those in other groups (p 0.05); The levels of serum IL-10 in 36.4% of all the patients with lung cancer on day 14 were higher than the upper limit of the normal value. In patients with benign lung diseases, perioperative changes were slight and non-significant. Conclusion: Serum IL-10 level is a reliable parameter for distinguishing benign lung disease from malignant ones. Defining preoperative and postoperative changes of serum IL-10 levels might be of prognostic value in patients with lung cancer

    To investigate the skin innervation and its clinical significance in late-stage chronic kidney disease (CKD). Case series. National Taiwan University Hospital, Taipei, Taiwan. Forty consecutive nondiabetic patients with late-stage CKD (14 female and 26 male; mean [SD] age, 60.7 [12.3] years), including 2 cases with stage 3 CKD, 6 with stage 4 CKD, and 32 with stage 5 CKD, ie, end-stage kidney disease. Clinical evaluation of neurological deficits, nerve conduction study, autonomic function tests, and a 3-mm-diameter skin biopsy specimen taken from the distal leg. Quantitation of epidermal innervation, parameters of nerve conduction study, R-R interval variability, and sympathetic skin response. Clinically, 21 patients (52.5%) were symptomatic with paresthesia over the limbs or autonomic symptoms. The intraepidermal nerve fiber (IENF) density was markedly reduced in patients with CKD compared with age- and sex-matched controls (mean [SD], 2.8 [2.0] vs 8.6 [2.8] fibers/mm; P Skin denervation was observed in 27 patients (67.5%). Fifteen patients (37.5%) had abnormalities on nerve conduction studies, and 29 patients (72.5%) had abnormal results on autonomic function tests. By analysis with multiple regression models, the IENF density was negatively correlated with the duration of renal disease (P = .02). Additionally, the R-R interval variability at rest was linearly correlated with the IENF density (P = .02) and the absence of sympathetic skin responses at the soles was associated with reduced IENF density (P = .03). Small-fiber sensory and autonomic neuropathies constitute the major form of neuropathy in late-stage CKD. Furthermore, skin denervation was associated with the duration of renal disease.

  20. The causes of skin damage and leg ulceration in chronic venous disease.

    Smith, Philip Coleridge

    2006-09-01

    Chronic venous disease with skin changes of the leg is a common condition affecting up to 1 in 20 people in westernized countries. The causes of this problem are not fully understood, although research in recent years has revealed a number of important mechanisms that contribute to the disease process. Patients with chronic venous disease suffer persistently raised pressures in their deep and superficial veins in the lower limb. Leucocytes become "trapped" in the circulation of the leg during periods of venous hyper-tension produced by sitting or standing. Studies of the plasma levels of neutrophil granule enzymes shows that these are increased during periods of venous hypertension, suggesting that this causes activation of the neutrophils. Investigation of the leucocyte surface ligands CD11b and CD62L shows that the more activated neutrophils and monocytes are sequestered during venous hypertension. Measurement of plasma levels of the soluble parts of the endothelial adhesion molecules VCAM, ICAM, and ELAM show that these are all elevated in patients with chronic venous disease compared to controls. Following 30 minutes of venous hypertension produced by standing, these levels are further increased. These data suggest that venous hypertension causes neutrophil and monocyte activation, which in turn causes injury to the endothelium. Chronic injury to the endothelium leads to a chronic inflammatory condition of the skin that we know clinically as lipodermatosclerosis. This is mediated by perivascular inflammatory cells, principally macrophages, in the skin microcirculation. These stimulate fibroblasts in the skin leading to tissue remodeling and laying down of fibrous tissue. Vascular endothelial growth factor stimulates proliferation of capillaries within the skin. Skin in this state has the potential to ulcerate in response to minor injury.

    Full text: For the evaluation of bone metastases in patients (pts) with cancer, 99mTcMDP bone scintigraphy is an important tool, but some limitations exist. One of these is the differential diagnosis of malignant and degenerative benign bone disease. The aim of this study was to differentiate them using 99mTcCitrate and 99mTcMDP scintigraphy. Methods: 39 pts (92 lesions) with known malignant or degenerative benign bone disease were studied. 23 pts had malignant bone disease (48 lesions, group 1), the other 16 pts had degenerative benign bone disease (44 lesions, group2), for which the results of 99mTcMDP scintigraphy were positive. In both groups, 99mTcCitrate scintigraphy was performed within a time interval of 2-7 days after 99mTcMDP scintigraphy (555∼740MBq. static, 3hr, planar or SPECT i m a g e s w h e n r e q u i r e d ) . The 99mTccitrate/99mTcMDP lesion-to-background radioisotope uptake ratio (RUR) was calculated for each lesion. Conventional techniques (histopathology, X-ray, CT, MRI and clinical follow up) were considered to be proof of the presence of bone metastases and degenerative benign bone disease. Results: Uptake of 99mTcMDP in the two groups is the same (1.96±0.25 vs. 1.87±0.21; t=1.178, P>0.20), while in 99mTcCitrate image, malignant lesions demonstrated a higher uptake of lesion activity than that of benign degenerative lesions (1.47±0.42 vs. 1.09±0.38; t=2.887, P<0.01). The mean 99mTccitrate/99mTcMDP RUR in the malignant group was significantly higher than the mean in the benign group (0.78±0.21 vs. 0.54±0.19; t=3.646, P<0.001). Conclusions: The preliminary results of the study confirm the usefulness and feasibility of 99mTcCitrate scintigraphy for differentiating malignant from benign degenerative lesions seen as areas of increased activity on 99mTcMDP bone scintigraphy.

    Full Text Available Objectives: We investigate the impact of occupational skin disease consultations among outpatients at the Dermatological Department, University Hospital, Northern Norway. Study design: From 1997 until 2004, 386 patients with occupational skin disease were examined and given advice on skin care, skin disease treatment, skin protection in further work, and on the legal rights of patients with this disease. Ten to fifteen years later, we wanted to look at these patients in terms of their work situation, the current status of their disease, the help they received from the labour offices, and their subjective quality of life. Material and methods: In the autumn of 2011 until the spring of 2012, a number of the patients examined in the period from 1997 to 2004 were selected and sent a questionnaire, which they were asked to answer and return, regarding their work situation and the progress and current status of their occupational disease. Results: A total of 153 (77% patients answered the questionnaire; 71% of these patients were still in work, and further 15% had old-age retired, 13% were working until then; 16% had retired early because of disability; 54% had changed jobs because of their occupational skin disease; 86% of the patients indicated that the skin disease had improved since our previous investigation. Conclusions: Our investigation into patients with occupational skin disease documented that the majority of patients who had received professional dermatological consultation and intervention offers were still in the labour market and had good control of their skin disease 10–15 years later. We discovered that 71% of the patients were still employed. 13% had remained in work until they became old age pensioners. Only 16% dropped out of work because of disability. These high percentages may indicate that our intervention has contributed positively to patients’ work conditions and the course of their skin disease.

We discovered that 71% of the patients were still employed. 13% had remained in work until they became old age pensioners. Only 16% dropped out of work because of disability. These high percentages may indicate that our intervention has contributed positively to patients' work conditions and the course of their skin disease.

    Objectives We investigate the impact of occupational skin disease consultations among outpatients at the Dermatological Department, University Hospital, Northern Norway. Study design From 1997 until 2004, 386 patients with occupational skin disease were examined and given advice on skin care, skin disease treatment, skin protection in further work, and on the legal rights of patients with this disease. Ten to fifteen years later, we wanted to look at these patients in terms of their work situation, the current status of their disease, the help they received from the labour offices, and their subjective quality of life. Material and methods In the autumn of 2011 until the spring of 2012, a number of the patients examined in the period from 1997 to 2004 were selected and sent a questionnaire, which they were asked to answer and return, regarding their work situation and the progress and current status of their occupational disease. Results A total of 153 (77%) patients answered the questionnaire; 71% of these patients were still in work, and further 15% had old-age retired, 13% were working until then; 16% had retired early because of disability; 54% had changed jobs because of their occupational skin disease; 86% of the patients indicated that the skin disease had improved since our previous investigation. Conclusions Our investigation into patients with occupational skin disease documented that the majority of patients who had received professional dermatological consultation and intervention offers were still in the labour market and had good control of their skin disease 10–15 years later. We discovered that 71% of the patients were still employed. 13% had remained in work until they became old age pensioners. Only 16% dropped out of work because of disability.

    The multiple neurofibromatosis is an autosomal dominant hereditary disease associated to malignant schwannoma in about 3% of the cases and very rarely to others cancers. The study provides information on the case of a 32 year-old woman who suffers from this disease and presented two synchronous cancers: a papillary carcinoma of thyroid and a malignant schwannoma of the chest wall. The thyroid tumour was managed with hemithyroidectomy, hormonotherapy and radiotherapy, and the lesion of the thoracic wall was treated with local radical resection application of Marlex mesh and rotation of a musculocutaneous flap of the dorsal muscle. A review of the literature on the clinical aspects of this association and the surgical techniques employed to cover the defect of the chest wall is presented. (authors)

    Autoimmune subepidermal blistering diseases of the skin and mucosae constitute a large group of sometimes devastating diseases, encompassing bullous pemphigoid, gestational pemphigoid, mucous membrane pemphigoid, epidermolysis bullosa acquisita, and anti-p200 pemphigoid. Their clinical presentation is polymorphic. These autoimmune blistering diseases are associated with autoantibodies that target distinct components of the basement membrane zone of stratified epithelia. These autoantigens represent structural proteins important for maintenance of dermo-epidermal integrity. Bullous pemphigoid (BP) is the most common subepidermal autoimmune blistering disease of the skin and mucosae. Although the disease typically presents with a generalized blistering eruption associated with itch, atypical variants with either localized bullous lesions or "non-bullous" presentations are observed in approximately 20% of patients. A peculiar form of BP typically associated with pregnancy is pemphigoid gestationis. In anti-p200 pemphigoid, patients present with tense blisters on erythematosus or normal skin resembling BP, with a predilection for acral surfaces. These patients have antibodies targeting the 200-kDa basement membrane protein. Epidermolysis bullosa is a rare autoimmune blistering disease associated with autoantibodies against type VII collagen that can have several phenotypes including a classical form mimicking dystrophic epidermolysis bullosa, an inflammatory presentation mimicking BP, or mucous membrane pemphigoid-like lesions. Mucous membrane pemphigoid (MMP) is the term agreed upon by international consensus for an autoimmune blistering disorder, which affects one or more mucous membrane and may involve the skin. The condition involves a number of different autoantigens in the basement membrane zone. It may result in severe complications from scarring, such as blindness and strictures. Diagnosis of these diseases relies on direct immunofluorescence microscopy studies

    Skin conditions and dermatological diseases associated with advanced age (e.g. fungal infection, dry skin and itch) receive increasingly attention in clinical practice and research. Cost and economic evaluations are important sources to inform priority setting and ressource allocation decisions in healthcare. The economics of skin conditions in aged populations has not been systematically reviewed so far. The aim of this mapping review was to summarize the economic evidence of selected skin conditions in the aged (65 + years). A mapping literature review and evidence summary was conducted. Searches were conducted in data bases Medline and Embase via OVID. Cinahl was searched using EBSCO. References lists of potential eligible studies, reviews, guidelines or other sources were screened for additional literature. For evaluation of methodological quality of full economic analyses the Consensus on Health Economic Criteria (CHEC) checklist was used. Database searches resulted in 1388 records. A total of 270 articles were read in full-text. Thirty-five publications were finally included in the data analysis reporting 38 economic analyses. Ten cost of illness analyses and 26 cost-effectiveness analyses reporting about pressure ulcers, skin tears, pressure ulcers, incontinence associated dermatitis and intertrigo/contact dermatitis/candidiasis treatment and prevention and onychomycosis testing were identified. Limited evidence indicated that low air loss beds were more cost effective than standard beds for prevention of pressure ulcers. Standardized skin care regimens seem to lower the incidence of pressure ulcers, skin tears and IAD but a cost saving effect was not always observed. Findings of this mapping review indicate that there is a paucity of high quality evidence regarding the economic impact of age-associated skin conditions and diseases. Substantial heterogeneity in terms of study design, evaluation perspective, time period, and way of cost estimation was

    Skin lesions can be defined as lesions that result in loss of tissues and their joints, and often this cutaneous skin process is a primary or secondary consequence of the structural changes in the skin itself. Subjects with peripheral arteripathies that develop chronic skin lesions in the lower extremities of the Western world are constantly increasing. We conducted a study on the etiologic incidence of chronic skin lesions in peripheral arterial disease CSLpa subjects in the lower limbs compared to subjects with chronic skin lesions CSL (controls). 30 subjects with peripheral atheropathies PA (22 F - 8 M mean age 74,5 ± 4,9) and with chronic skin lesions (CSLpa) in the lower limbs "A" group were admitted to our study according to a randomized and compared to 30 no peripheral atheropathies subjects (19 F-11 M, mean age 81,5 ± 7,3 - controls) group B with chronic skin lesions (CSL). These two groups "A" and "B" have been studied and compared on the basis of infectious etiology responsible for the infectious skin process. In the subjects of the "A" group we found a 12 positive assay of 40.0% of the examinations, while in the group "B" we achieved a total cultured positivity of 9 cases corresponding to 30.0% of the examinations . For the number of bacterial species identified for "A" group we obtained 3 mono microbial and 6 poly microbial bacteriological tests and for group "B" we observed 7 mono microbial and 2 poly microbial tests. All bacteriological isolates showed "in vitro" sensitivity to satisfactory ciprofloxacin with MICs range of 0.78-1.56mg/L. The data observed after 4 weeks after the amniotic membrane (MA) in the two study groups A and B were respectively the following: and for group A 50% scarring, 46.6% partial resolution and in one case worsening for the B-healing group in 63.3%, the partial resolution in the remaining 36.6. The data from this study show a different etiology between subjects with CSLpa than subjects with CSL. This phenomenon confirms

    Advanced glycation end product (AGE) accumulation is thought to be a measure of cumulative metabolic stress that has been reported to independently predict cardiovascular disease in diabetes and renal failure. The aim of this study was to evaluate the association between AGE accumulation, measured as skin autofluorescence, and the progression of renal disease in pre-dialysis patients with chronic kidney disease (CKD). Skin autofluorescence was measured noninvasively with an autofluorescence reader at baseline in 449 pre-dialysis patients with CKD. The primary end point was defined as a doubling of serum creatinine and/or need for dialysis. Thirty-three patients were lost to follow-up. Forty six patients reached the primary end point during the follow-up period (Median 39 months). Kaplan-Meier analysis showed a significantly higher risk of development of the primary end points in patients with skin autofluorescence levels above the optimal cut-off level of 2.31 arbitrary units, derived by receiver operator curve analysis. Cox regression analysis revealed that skin autofluorescence was an independent predictor of the primary end point, even after adjustment for age, gender, smoking history, diabetes, estimated glomerular filtration rate and proteinuria (adjusted hazard ratio 2.58, P = 0.004). Tissue accumulation of AGEs, measured as skin autofluorescence, is a strong and independent predictor of progression of CKD. Skin autofluorescence may be useful for risk stratification in this group of patients; further studies should clarify whether AGE accumulation could be one of the therapeutic targets to improve the prognosis of CKD.

    2008-01-01

    Purpose: Subsequent malignant neoplasms (SMNs) are a dominant cause of morbidity and mortality in children treated for Hodgkin's disease (HD). We evaluated select demographic and therapeutic factors associated with SMNs, specifically gender and radiation dose. Methods and Materials: A total of 930 children treated for HD at five institutions between 1960 and 1990 were studied. Mean age at diagnosis was 13.6 years, and mean follow-up was 16.8 years (maximum, 39.4 years). Treatment included radiation alone (43%), chemotherapy alone (9%), or both (48%). Results: We found that SMNs occurred in 102 (11%) patients, with a 25-year actuarial rate of 19%. With 15,154 patient years of follow-up, only 7.18 cancers were expected (standardized incidence ratio [SIR] = 14.2; absolute excess risk [AER] = 63 cases/10,000 years). The SIR for female subjects, 19.93, was significantly greater than for males, 8.41 (p < 0.0001). After excluding breast cancer, the SIR for female patients was 15.4, still significantly greater than for male patients (p = 0.0012). Increasing radiation dose was associated with an increasing SIR (p = 0.0085). On univariate analysis, an increased risk was associated with female gender, increasing radiation dose, and age at treatment (12-16 years). Using logistic regression, mantle radiation dose increased risk, and this was 2.5-fold for female patients treated with more than 35 Gy primarily because of breast cancer. Conclusions: Survivors of childhood HD are at risk for SMNs, and this risk is greater for female individuals even after accounting for breast cancer. Although SMNs occur in the absence of radiation therapy, the risk increases with RT dose

    The aim of this work was to analyze the public health indicators for circulatory heart diseases and malignant neoplasms in the population younger than 65 in the City of Zagreb, Croatia, and compare them with the European Union (EU) countries. The purpose was to evaluate the situation and propose the public health preventive measures. The study population were Zagreb citizens aged 0-64 according to the 2001 census. Total Zagreb population was 779145, making 17.6% of total Croatian population. Data from the Croatian Bureau of Statistics and Dr Andrija Stampar Institute of Public Health were used. The standardized 0-64 mortality rates of the selected diseases 2006-2010 were used in the analysis. In 2010, the standardized mortality rates of all analyzed diseases were significantly higher in Zagreb population aged 0-64 than the EU averages except for cervical cancer. In 2010, the mortality rates in Zagreb population aged 0-64 were as follows: circulatory system diseases 61.22, ischemic heart disease 28.99, cerebrovascular diseases 12.51, malignant neoplasms 94.69, tracheal and lung cancer 24.92, breast cancer 21.08 and cervical cancer 2.05. Standardized mortality rates in Zagreb population aged 0-64 for circulatory system were lower than for Croatia (61.22 vs. 63.25), but higher for malignant neoplasms (94.69 vs. 91.2), except for cervical cancer (2.05 vs. 3.14). High standardized mortality rates for the selected diseases in the City of Zagreb, Croatia, were observed. The rates were higher in Zagreb population compared to EU averages except for cervical cancer. This situation urges revision of the public health strategy and implementation of more intensive preventive and screening measures to reduce the risk factors.

    2018-01-01

    Overall, the 308 nm Excimer laser enables not only a more effective and safer UVB therapy than classical UV phototherapy, but also targeted irradiation in higher doses with a lower cumulative load, which results in faster healing of mainly circumscribed skin changes. This also applies to therapy-resistant residual lesions which, despite systemic therapy, did not diminish. Combination therapies usually improve the result and enable the dose of UVB and systemic medication to be reduced. Excimer laser therapy can be used for an increasing number of skin diseases, especially those that respond to phototherapy or photochemotherapy.

    Tangier disease (TD) is characterized by a deficiency of high density lipoprotein (HDL) in plasma and patients with TD have an increased risk for coronary artery disease (CAD). Recently, we reported that fibroblasts from TD exhibited large and flattened morphology, which is often observed in senescent cells. On the other hand, data have accumulated to show the relationship between cellular senescence and development of atherosclerotic CAD. The aim of the present study was to investigate whether TD fibroblasts exhibited cellular senescence. The proliferation of TD fibroblasts was gradually decreased at population doubling level (PDL) ∼10 compared with control cells. TD cells practically ceased proliferation at PDL ∼30. DNA synthesis was markedly decreased in TD fibroblasts. TD cells exhibited a higher positive rate for senescence-associated β-galactosidase (SA-β-gal), which is one of the biomarkers of cellular senescence in vitro. These data showed that TD cells reached cellular senescence at an earlier PDL compared with controls. Although, there was no difference in the telomere length of fibroblasts between TD and controls at the earlier passage (PDL 6), the telomere length of TD cells was shorter than that of controls at the late passage (PDL 25). Taken together, the current study demonstrates that the late-passaged TD fibroblasts showed senescent phenotype in vitro, which might be related to the increased cardiovascular manifestations in TD patients

    Rosacea is a chronic skin disorder that presents with abnormal vascular and inflammatory conditions. Clinical manifestations include flushing, facial erythema, inflammatory papules and pustules, telangiectasias, edema, and watery or irritated eyes. To discuss the evolving pathophysiology of rosacea, factors involved in promoting the chronic vascular and inflammatory abnormalities seen in rosacea, and the available drug therapies for the condition. Chronic inflammation and vascular changes are believed to be underlying factors in the pathophysiology of rosacea. Aberrant cathelicidin expression, elevated kallikrein 5 (KLK5) proteolytic activity, and altered toll-like receptor 2 (TLR2) expression have been reported in rosacea skin leading to the production of proinflammatory cytokines. Until recently, drug therapies only targeted the inflammatory lesions (papules and pustules) and transient erythema associated with these inflammatory lesions of rosacea. Brimonidine tartrate gel 0.5% was recently approved for the treatment of persistent (nontransient) facial erythema of rosacea, acting primarily on the cutaneous vascular component of the disease. Rosacea is a chronic vascular and inflammatory skin disease. Understanding the role of factors that trigger the onset of rosacea symptoms and exacerbate the condition is crucial in treating this skin disease.

    Actively searching for leprosy, other skin diseases and BCG vaccination scars amongst school children from Agua de Dios, the municipality having the highest prevalence of leprosy in Colombia. A clinical examination of the children was carried out by nurses, interns, general practitioners and experts on leprosy. Skin smear tests and skin biopsies were performed when the clinical findings suggested leprosy. Anti-phenolic glycolipid antibodies in blood were determined in special cases. 86 % of the 2 844 school children were examined; 833 had skin diseases and 16 % of these required evaluation by specialists. Four new cases of paucibacillary leprosy, two indeterminate and two primary polyneuritic cases were found. Pediculosis capitis, pityriasis alba, tinea versicolor, hypopigmented nevus, insect bites and miliaria were frequently detected. BCG vaccination scars were absent in 387 children; following several logistical problems, they were vaccinated. Four children had signs of childhood abuse. An 11-year-old girl presented hypopigmented mycosis fungoides. All diseases and conditions found were treated. The community received information regarding the results, emphasising the importance of an early diagnosis of leprosy. The incidence of leprosy found (16/10,000) was 123 times higher than the rest of the country's incidence. It is advisable to continue clinical examinations in Agua de Dios and research into risk factors for acquiring leprosy.

Skin - both in health and diseases had caught attention of the Vedic sages. Skin was not merely an organ of attraction and look but its colour was important socially. Mentions of various diseases like leprosy, guinea worm, jaundice etc., are interesting. Mention of different disorders of the nails and hair are also there, though in a very primitive and mystic form. Management strategy was consisted of herbs, amulates, chanting of mantras, touching the body, uses of water and sunrays etc. This may be presumed that this Veda founded the base for the Βyurveda of the later period.

    During the Second World War, thousands of captured British and Commonwealth troops were interned in prisoner-of-war (POW) camps in the Far East. Imprisonment was extremely harsh, and prisoners developed multiple pathologies induced by physical hardship, tropical infections and starvation. Immediately after the war, several POW doctors published their clinical experiences, including reports of skin disease caused by malnutrition. The most notable deficiency dermatoses seen in Far East POWs were ariboflavinosis (vitamin B2 or riboflavin deficiency) and pellagra (vitamin B3 or niacin deficiency). A lack of vitamin B2 produces a striking inflammatory disorder of scrotal skin. Reports of pellagra in POWs documented a novel widespread eruption, developing into exfoliative dermatitis, in addition to the usual photosensitive dermatosis.

    This study aimed to determine the prevalence of and risk factors for skin problems among flood victims and army personnel during the 2011 floods in Thailand. To determine the prevalence of and risk factors for skin symptoms, standardized questionnaires were used to collect demographic data, current skin symptoms, history of water exposure, and sanitary behaviors. A certified dermatologist evaluated those who presented with skin problems and provided diagnoses. Univariate and multivariate analyses were performed to assess independent risk factors for skin symptoms. The most prevalent skin disease was irritant contact dermatitis. Flood victims showed a higher prevalence of skin symptoms compared with army personnel. Development of skin symptoms after exposure to floodwater was also observed earlier among flood victims. Having a history of skin diseases and delayed skin cleaning after exposure were also significant risk factors for the development of skin symptoms. This information might be used as guidelines for protecting military personnel and to educate the general public regarding flood disaster management.

    Full Text Available While hydroxycarbamine (hydroxyurea, HU has less and less indications in malignant hemopathies, it represents the only widely used drug which modifies sickle cell disease pathogenesis. Clinical experience with HU for patients with sickle cell disease has been accumulated over the past 25 years in Western countries. The review of the literature provides increasing support of safety and efficacy in both children and adults for reducing acute vaso-occlusive events including pain episodes and acute chest syndrome. HU has become the standard-of-care for sickle cell anemia, but remains underused. Barriers to its use should be identified and overcome.

    Systemic sclerosis (SSc) is a multi-organ connective tissue disease characterized by immune dysregulation and organ fibrosis. Severe organ involvement, especially of the skin and lung, is the cause of morbidity and mortality in SSc. Interstitial lung disease (ILD) includes multiple lung disorders in which the lung tissue is fibrotic and stiffened. The purpose of this study was to translate ultrasound surface wave elastography (USWE) for assessing patients with SSc and/or ILD via measuring surface wave speeds of both skin and superficial lung tissue. Forty-one patients with both SSc and ILD and 30 healthy patients were enrolled in this study. An external harmonic vibration was used to generate the wave propagation on the skin or lung. Three excitation frequencies of 100, 150 and 200 Hz were used. An ultrasound probe was used to measure the wave propagation in the tissue non-invasively. Surface wave speeds were measured on the forearm and upper arm of both left and right arm, as well as the upper and lower lungs, through six intercostal spaces of patients and healthy patients. Viscoelasticity of the skin was calculated by the wave speed dispersion with frequency using the Voigt model. The magnitudes of surface wave speed and viscoelasticity of patients' skin were significantly higher than those of healthy patients (p wave speeds of patients' lung were significantly higher than those of healthy patients (p ionizing technique for measuring both skin and lung surface wave speed and may be useful for quantitative assessment of SSc and/or ILD.

    The purpose of this study was to investigate the potential correlation between the presence and size of the cisterna chyli (CC) on computed tomography (CT) and the presence of cardiovascular disease. Materials and methods: Out of a 3000-patient cohort 2599 patients who received a CT examination of the chest and/or abdomen with measurable inferior vena cava and azygos vein were included in this retrospective study. To assess the presence of cardiovascular disease the following parameters were recorded from the PACS or clinical information system: diameter of vena cava and azygos vein, presence of ascitis, serum creatinine, history of congestive heart failure, coronary artery disease or arterial hypertension and medication (diuretics, beta-blocker). In addition the volume of the CC and the presence or absence of malignant disease were recorded. Mean values (vessel diameters, creatinine) or percentages were calculated and compared for the groups with (n = 416) and without (n = 2183) a cisterna. Multivariate logistic regression analysis was performed for all parameters to identify the potential association with the presence and size of a cisterna. In addition the simultaneous influence of the parameter malignancy, cardiovascular disease and age on presence and size of the CC was analyzed in a logistic regression model. Results: The presence or absence of a CC was not associated with any of the measured parameter. Regarding the size of the CC, there was a positive correlation with the diameter of the azygos vein, the presence of ascitis and diuretic medication. The influences of malignancy, elevated central venous pressure and age on the development of a CC proved to be highly significant but could not be separated or quantified. Conclusion: The volume of the cisterna chyli is influenced by pathologic states with an increased central venous pressure, while the presence or absence of the cisterna seems to be independent of those factors.

    2017-01-01

    Full Text Available Worldwide estimates of oral submucous fibrosis (OSMF show a confinement to Indians and Southeast Asians. In India, the prevalence of OSMF has increased over the past four decades from 0.03% to 6.42%. The condition is well recognized for its malignant potential rate of 7-30%. The condition has a multifactorial etiology and may remain either stationary or become severe, leaving an individual physically challenged both physically and psychologically. Hence, the study aims at reviewing studies done on various etiological factors leading to its onset. Their analysis may serve as an adjunct in defining the broad spectrum of the causation of this potentially malignant disorder.

    The presence in the brain of α-synuclein containing Lewy neurites, or bodies, is the histological hallmark of Parkinson's disease (PD). The discovery of α-synuclein aggregates in nerve endings of the heart, digestive tract, and skin has lent support to the concept of PD as a systemic disease. Our goals were, first, to demonstrate the presence of α-synuclein inclusions in the skin and, second, to detect quantitative differences between patients with PD and atypical parkinsonism (AP). Skin biopsies were taken from 67 patients and 20 controls. The biopsies underwent immunohistochemistry (IHC) and immunofluorescence (IF) testing for α-synuclein, whereupon its presence was quantified as the percentage of positive cells. Patients were divided into those with PD and those with AP. AP patients included AP with neurodegenerative disease (proteinopathies) and secondary AP. Sixty-seven patients (34 with PD) and 20 controls were recruited. In the PD group, α-synuclein was detected in 58% of the cells in the spinous cell layer (SCL), 62% in the pilosebaceous unit (PSU), and 58% in the eccrine glands (EG). The AP-proteinopathies group showed 7%, 7%, and 0% expression of α-synuclein, respectively. No expression was found in the skin of the control group. The expression of α-synuclein in the skin was relatively high in the PD group, scarce in AP, and null for the individuals in the control group. While these findings require further confirmation, this minimally invasive technique may aid in the improvement of the accuracy of PD diagnoses.

    In 2015, the lumpy skin disease virus spread throughout the Russian Federation. Following a modified stamping-out campaign, the disease re-emerged with a greater incidence across 16 regions of Southern and Central Russia. A total of 313 outbreaks were reported to OIE. The highest outbreak frequency was observed in the republics of Chechnya (108), Kalmykiya (57), and Ingushetiya (35). The disease cases predominantly occurred in June and July 2016, starting from May to December; however, no association between outbreaks and altitudes was identified (p > .05). Samples taken from infected cattle were subjected to PCR analysis, which identified the genome of the virus most frequently in skin nodules (78%), nasal swabs (23.4%), blood (13%) and sera (14.5%). Interestingly, LSDV genome was occasionally identified in lung and milk samples. Based on the PRO30 sequence analysis, lumpy skin disease virus (LSDV) strains circulating in Russia were all identical and fell within the cluster of field LSDV found worldwide. © 2018 Blackwell Verlag GmbH.

    Full Text Available UV radiation (UV is classified as a “complete carcinogen” because it is both a mutagen and a non-specific damaging agent and has properties of both a tumor initiator and a tumor promoter. In environmental abundance, UV is the most important modifiable risk factor for skin cancer and many other environmentally-influenced skin disorders. However, UV also benefits human health by mediating natural synthesis of vitamin D and endorphins in the skin, therefore UV has complex and mixed effects on human health. Nonetheless, excessive exposure to UV carries profound health risks, including atrophy, pigmentary changes, wrinkling and malignancy. UV is epidemiologically and molecularly linked to the three most common types of skin cancer, basal cell carcinoma, squamous cell carcinoma and malignant melanoma, which together affect more than a million Americans annually. Genetic factors also influence risk of UV-mediated skin disease. Polymorphisms of the melanocortin 1 receptor (MC1R gene, in particular, correlate with fairness of skin, UV sensitivity, and enhanced cancer risk. We are interested in developing UV-protective approaches based on a detailed understanding of molecular events that occur after UV exposure, focusing particularly on epidermal melanization and the role of the MC1R in genome maintenance.

    Conventional optical coherence tomography (OCT) enables the visualization of morphological changes of skin cancer. The use of OCT in the diagnostic investigation and in the therapy decision of non-melanoma skin cancer and other skin changes is already established, and has found its way into routine...... practice. With the development of speckle-variance OCT, also named dynamic OCT (D-OCT), the vascular architecture and the blood flow of the skin can be displayed in vivo and in 3D. This novel angiographic variant of OCT offers the ability to visualize and measure vessel morphology providing a new insight...... into healthy, inflammatory and neoplastic skin lesions such as malignant melanoma. This review focuses on the possibilities of using D-OCT on healthy and diseased skin. We suggest and illustrate key diagnostic characteristics by analyzing the initial publications and preliminary unpublished data on vessel...

    Full Text Available During the recent period, dermoscopy has yielded improvement in the early disclosure of various atypical melanocytic neoplasms (AMN of the skin. Beyond this clinical procedure, AMN histopathology remains mandatory for establishing their precise diagnosis. Of note, panels of experts in AMN merely report moderate agreement in various puzzling cases. Divergences in opinion and misdiagnosis are likely increased when histopathological criteria are not fine-tuned and when facing a diversity of AMN types. Furthermore, some AMN have been differently named in the literature including atypical Spitz tumor, metastasizing Spitz tumor, borderline and intermediate melanocytic tumor, malignant Spitz nevus, pigmented epithelioid melanocytoma or animal-type melanoma. Some acronyms have been further suggested such as MELTUMP (after melanocytic tumor of uncertain malignant potential and STUMP (after Spitzoid melanocytic tumor of uncertain malignant potential. In this review, such AMN at the exclusion of cutaneous malignant melanoma (MM variants, are grouped under the tentative broad heading skin melanocytoma. Such set of AMN frequently follows an indolent course, although they exhibit atypical and sometimes worrisome patterns or cytological atypia. Rare cases of skin melanocytomas progress to loco regional clusters of lesions (agminate melanocytomas, and even to regional lymph nodes. At times, the distinction between a skin melanocytoma and MM remains puzzling. However, multipronged immunohistochemistry and emerging molecular biology help profiling any malignancy risk if present.

    Skin inflammation plays a central role in the pathophysiology and symptoms of diverse chronic skin diseases including atopic dermatitis (AD). In this study, we examined if caffeic acid phenethyl ester (CAPE), a skin-permeable bioactive compound from propolis, was protective against skin inflammation using in vitro cell system and in vivo animal disease models. CAPE suppressed TNF-α-induced NF-κB activation and expression of inflammatory cytokines in human keratinocytes (HaCaT). The potency and efficacy of CAPE were superior to those of a non-phenethyl derivative, caffeic acid. Consistently, topical treatment of CAPE (0.5 %) attenuated 12-O-tetradecanoylphorbol-13-acetate(TPA)-induced skin inflammation on mouse ear as CAPE reduced ear swelling and histologic inflammation scores. CAPE suppressed increased expression of pro-inflammatory molecules such as TNF-α, cyclooxygenase-2 and inducible NO synthase in TPA-stimulated skin. TPA-induced phosphorylation of IκB and ERK was blocked by CAPE suggesting that protective effects of CAPE on skin inflammation is attributed to inhibition of NF-κB activation. Most importantly, in an oxazolone-induced chronic dermatitis model, topical application of CAPE (0.5 and 1 %) was effective in alleviating AD-like symptoms such as increases of trans-epidermal water loss, skin thickening and serum IgE as well as histologic inflammation assessment. Collectively, our results propose CAPE as a promising candidate for a novel topical drug for skin inflammatory diseases.

    Vulvar intraepithelial neoplasia (VIN) and vulvar Paget disease are managed with either vulvectomy, destructive treatments (laser, antimitotic drugs) or immunostimulants. All these options are associated with functional complications. The purpose of this study was to evaluate the surgical technique consisting of skinning vulvectomy with split-thickness skin graft, and its effect on overall quality of life and sexual function. A retrospective study was conducted on thirteen patients who underwent skinning vulvectomy with split-thickness skin graft between 1999 and 2009. Overall quality of life and sexual function were assessed with the Medical Outcome Study Short Form 36 (MOS SF-36) and Female Sexual Function Index (FSFI), respectively. The median age of patients was 54 (range: 33-77) years. Three patients had Paget disease and 10 patients had VIN lesions. The excision margins were clear in 46% of cases. The incidence of occult cancer was 31%. The mean follow-up period was 77 (±35) months. Four patients experienced a relapse of their intraepithelial disease. The mean disease-free survival was 58 (±44) months. There was no significant difference in MOS SF-36 scores between the study population and the general population. The patients assessed with the FSFI regained normal sexual function after the surgical procedure. Skinning vulvectomy with split-thickness skin graft is a feasible technique yielding good results in terms of quality of life and sexual function. It enables occult cancer to be diagnosed in patients with VIN or Paget disease. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Chronic venous disease (CVD) is a common venous disease of the lower extremities and patients often develop symptoms of itching and skin roughness. An easy to use and objective skin examination was recently developed that allows measurement of the level of stratum corneum content and transepidermal water loss (TEWL), which can indicate the status of the barrier function of the stratum corneum. Previous studies demonstrated that histamine production from mast cells, and tryptase and matrix metalloprotease-9 levels were associated with skin inflammation. This study aimed to clarify the relationship between dry skin and inflammatory mediators that mediate the skin symptoms of CVD subjects. The study enrolled 27 subjects with CVD and a control group consisting of 9 volunteers. The itching onset frequency was higher in women (70.4%) compared with men (50.0%). To analyze the mechanisms involved in itching we measured blood inflammatory mediators pre- and post-sclerotherapy. There was a significant decrease in Substance P, histamine, IgE, and tryptase levels post-sclerotherapy compared with those at pre-sclerotherapy. These levels were associated with the severity of itching. In addition, compared with the control subjects, there was a significant increase in the stratum corneum water content and a decrease in the TEWL in the 27 patients with CVD. This was associated with a decrease in the itching symptoms. Our findings indicate that sclerotherapy decreased levels of inflammatory mediators, increased stratum corneum water content and decreased TEWL, which coincided with reduced itching in CVD patients, indicating they might be therapeutic targets.

    Skin cancer is a worldwide health problem. It is the most common cancer in the countries with a large white population; furthermore, the incidence of malignant melanoma, the most dangerous form of skin cancer, has been increasing steadily over the last three decades. There is an urgent need to develop in-vivo, noninvasive diagnostic tools for the disease. This paper attempts to response to the challenge by introducing a simple and fast method based on polarization and laser speckle. The degree of maintaining polarization estimates the fraction of linearly maintaining polarization in the backscattered speckle field. Clinical experiments of 214 skin lesions including malignant melanomas, squamous cell carcinomas, basal cell carcinomas, nevi, and seborrheic keratoses demonstrated that such a parameter can potentially diagnose different skin lesion types. ROC analyses showed that malignant melanoma and seborrheic keratosis could be differentiated by both the blue and red lasers with the area under the curve (AUC) = 0.8 and 0.7, respectively. Also malignant melanoma and squamous cell carcinoma could be separated by the blue laser (AUC = 0.9), while nevus and seborrheic keratosis could be identified using the red laser (AUC = 0.7). These experiments demonstrated that polarization could be a potential in-vivo diagnostic indicator for skin diseases.

    The transmission of puffy skin disease (PSD) to rainbow trout Oncorhynchus mykiss Walbaum was tested in the laboratory by conducting co-habitation challenges with puffy skin (PS)-affected fish (Trojans) collected from the field. Two separate challenges were conducted using Trojans sourced from two different sites and diploid (first trial) or triploid (second trial) naïve fish. PSD-specific clinical signs were observed in both groups of naïve fish, with 66% of the fish sampled during the challenges showing signs of varying severity. The first clinical features of PSD were presented as white oval skin patches on one or both flanks 15-21 days post-challenge (dpc). The extent of the lesions ranged from 10 to 90% of the body surface, depending on the severity of the lesion. Both the severity and number of affected fish increased during the challenge. Macroscopically, oedema of the skin and multifocal petechial haemorrhaging were observed towards the end of the trials. Abnormal fish behaviour consisting of "flashing" and excessive mucous production was noted from 15 dpc onwards. Fish with severe PSD lesions also displayed inappetence and associated emaciation. Rodlet cells were observed in 41% of the fresh skin scrapes analysed from the second trial. Histologically epidermal oedema was observed in 31% of the naive fish showing gross pathology, with additional 12% displaying epidermal hyperplasia, mostly observed at the end of the challenge. Other concomitant features of the PSD lesions in challenged fish were epithelial erosion and sloughing, and occasionally mild or focal inflammation. No consistent pathology of internal organs was observed. The parasites Ichthyophthirius multifiliis and Ichthyobodo necator were observed in skin samples of a proportion of naïve challenged fish and in Trojans but not in control fish. The presence of these and other known fish pathogens in the skin of PSD-fish was confirmed by high-throughput sequencing analysis. In summary, we have

    Full Text Available Abstract Introduction Malignant pleural mesothelioma was once a rare finding but its incidence is increasing worldwide, most likely because of widespread exposure to asbestos. Although complete surgical resection is considered the only curative treatment, the results of surgery have shown a median survival time of only one year. In inoperable cases, chemotherapy, radiotherapy, and a combination of both have been considered as palliative therapy. Therefore, outcomes for inoperable cases have been poor. Here, we report the case of a long-term survivor treated with hyperthermia and chemotherapy. Case presentation A 61-year-old Japanese man with a performance status of 1 due to chest pain was referred to our hospital. He had a history of asbestos exposure for approximately five years. A computed tomography scan showed diffuse extensive right pleural thickening with small nodular lesions, and video-assisted thoracoscopy revealed tumor invasion of the ipsilateral chest wall muscles. The histopathologic findings were consistent with a diagnosis of malignant pleural mesothelioma (sarcomatoid type. The tumor was diagnosed as being stage cT3N0M0. Our patient refused any invasive therapies including surgery and radiotherapy, and was therefore treated with hyperthermia and systemic chemotherapy with agents such as cisplatin and irinotecan. He underwent three hyperthermia sessions and a single course of chemotherapy without any severe complications. One month after treatment, a follow-up computed tomography scan showed no definitive abnormality in the thoracic space. Our patient has subsequently survived without any evident disease for more than seven years. Conclusions The combination of hyperthermia and chemotherapy may be a novel and safe therapeutic option for malignant pleural mesothelioma, and can be considered for patients ineligible for radical treatment. Further clinical studies of the combination of hyperthermia and chemotherapy are needed to

    Retinoic acid inducible-gene I (RIG-I) functions as one of the major sensors of RNA viruses. DDX58 , which encodes the RIG-I protein, has been newly identified as a susceptibility gene in psoriasis. Here, we show that the activation of RIG-I by 5'ppp-dsRNA, its synthetic ligand, directly causes the production of IL-23 and triggers psoriasis-like skin disease in mice. Repeated injections of IL-23 to the ears failed to induce IL-23 production and a full psoriasis-like skin phenotype, in either germ-free or RIG-I-deficient mice. RIG-I is also critical for a full development of skin inflammation in imiquimod (IMQ)-induced psoriasis-like mouse model. Furthermore, RIG-I-mediated endogenous IL-23 production was mainly confined to the CD11c + dendritic cells (DCs) via nuclear factor-kappa B (NF-κB) signaling, and stimulated RIG-I expression in an auto-regulatory feedback loop. Thus, our data suggest that the dysregulation in the antiviral immune responses of hosts through the innate pattern recognition receptors may trigger the skin inflammatory conditions in the pathophysiology of psoriasis. © 2017 The Authors.

  18. Topical PDT in the Treatment of Benign Skin Diseases: Principles and New Applications

    Directory of Open Access Journals (Sweden)

    2015-09-01

    Full Text Available Photodynamic therapy (PDT uses a photosensitizer, light energy, and molecular oxygen to cause cell damage. Cells exposed to the photosensitizer are susceptible to destruction upon light absorption because excitation of the photosensitizing agents leads to the production of reactive oxygen species and, subsequently, direct cytotoxicity. Using the intrinsic cellular heme biosynthetic pathway, topical PDT selectively targets abnormal cells, while preserving normal surrounding tissues. This selective cytotoxic effect is the basis for the use of PDT in antitumor treatment. Clinically, PDT is a widely used therapeutic regimen for oncologic skin conditions such as actinic keratosis, squamous cell carcinoma in situ, and basal cell carcinoma. PDT has been shown, under certain circumstances, to stimulate the immune system and produce antibacterial, and/or regenerative effects while protecting cell viability. Thus, it may be useful for treating benign skin conditions. An increasing number of studies support the idea that PDT may be effective for treating acne vulgaris and several other inflammatory/infective skin diseases, including psoriasis, rosacea, viral warts, and aging-related changes. This review provides an overview of the clinical investigations of PDT and discusses each of the essential aspects of the sequence: its mechanism of action, common photosensitizers, light sources, and clinical applications in dermatology. Of the numerous clinical trials of PDT in dermatology, this review focuses on those studies that have reported remarkable therapeutic benefits following topical PDT for benign skin conditions such as acne vulgaris, viral warts, and photorejuvenation without causing severe side effects.

    Two cases of cytomegalic inclusion disease complicating chronic granulocytic leukemia and subacute lymphocytic leukemia in adult Japanese males in Nagasaki, Japan are reported. Both cases had concomitant pulmonary infection by pneumocystis carinii and both were exposed to the atomic bomb in 1945. It is believed these are the first reported autopsy cases of adult cytomegalic inclusion disease in which typical cytomegalic inclusion bodies were seen in the parenchymal cells of the salivary glands. Previously reported cases of adult cytomegalic inclusion disease complicating leukemia and malignant lymphoma are briefly summarized. Present knowledge of the relationship between cytomegalic and pneumocystis infections and association with lymphoma and leukemia is reviewed. The possible roles of chemotherapeutic agents and of radiation in the development of the cytomegalic and pneumocystis infections are also briefly discussed. 43 references, 4 figures, 2 tables.

    The visual scoring method has been used as a subjective evaluation of pigmentary skin disorders. Severity of pigmentary skin disease, especially melasma, is evaluated using a visual scoring method, the MASI (melasma area severity index). This study differentiates between epidermal and dermal pigmented disease. The study was undertaken to determine methods to quantitatively measure the severity of pigmentary skin disorders under ultraviolet illumination. The optical imaging system consists of illumination (white LED, UV-A lamp) and image acquisition (DSLR camera, air cooling CMOS CCD camera). Each camera is equipped with a polarizing filter to remove glare. To analyze images of visible and UV light, images are divided into frontal, cheek, and chin regions of melasma patients. Each image must undergo image processing. To reduce the curvature error in facial contours, a gradient mask is used. The new method of segmentation of front and lateral facial images is more objective for face-area-measurement than the MASI score. Image analysis of darkness and homogeneity is adequate to quantify the conventional MASI score. Under visible light, active lesion margins appear in both epidermal and dermal melanin, whereas melanin is found in the epidermis under UV light. This study objectively analyzes severity of melasma and attempts to develop new methods of image analysis with ultraviolet optical imaging equipment. Based on the results of this study, our optical imaging system could be used as a valuable tool to assess the severity of pigmentary skin disease. © 2017 John Wiley & Sons A/S.

    To assess whether the cutaneous features in patients with dengue fever are associated with abnormal blood biochemistry, complications, and poor disease outcome. Forty five patients with dengue fever were identified at a medical center in Kaohsiung, Taiwan, from September to November 2014. All cases were exclusively caused by type 1 dengue virus. Patients were classified into two groups, based on the presence or absence of skin rash, and their rash was subclassified into maculopapular, morbilliform, and petechial types. Clinical symptoms, laboratory data, disease outcome, and complications were compared between the two groups. Thirty two patients with dengue fever developed skin rash (SP group, n = 32) while the rest of 13 did not (SN group, n = 13). The patient numbers in the maculopapular, morbilliform, and petechial group were 4, 21, and 7, respectively. The SP group was younger (P = 0.001), experienced more pruritus (P = 0.008) and more swollen palms/soles (P = 0.015) than the SN group. However, the SN group had greater genital mucosa involvement (P = 0.008), higher platelet transfusion rate (P = 0.003), and lower hemoglobin and hematocrit levels (P = 0.030) than the SP group. Patients with morbilliform lesions had a higher incidence of palm/sole swelling, less genital mucosal involvement, and a lower platelet transfusion rate than did patients with maculopapular or petechial lesions. Cutaneous manifestations provide an important clue to dengue fever. In patients with dengue fever, those with skin rash tend to have itching and swelling of the palms/soles, however, those without skin rash tend to have more complications and poor disease outcomes.

    The production of the oncometabolite 2-hydroxyglutarate (2-HG) has been associated with c-MYC overexpression. c-MYC also regulates glutamine metabolism and drives progression of asymptomatic precursor plasma cell (PC) malignancies to symptomatic multiple myeloma (MM). However, the presence of 2-HG and its clinical significance in PC malignancies is unknown. By performing 13C stable isotope resolved metabolomics (SIRM) using U[13C6]Glucose and U[13C5]Glutamine in human myeloma cell lines (HMCLs), we show that 2-HG is produced in clonal PCs and is derived predominantly from glutamine anaplerosis into the TCA cycle. Furthermore, the 13C SIRM studies in HMCLs also demonstrate that glutamine is preferentially utilized by the TCA cycle compared with glucose. Finally, measuring the levels of 2-HG in the BM supernatant and peripheral blood plasma from patients with precursor PC malignancies such as smoldering MM (SMM) demonstrates that relatively elevated levels of 2-HG are associated with higher levels of c-MYC expression in the BM clonal PCs and with a subsequent shorter time to progression (TTP) to MM. Thus, measuring 2-HG levels in BM supernatant or peripheral blood plasma of SMM patients offers potential early identification of those patients at high risk of progression to MM, who could benefit from early therapeutic intervention.

    Lumpy skin disease is of significant economic impact for the cattle industry in Africa. The disease is currently spreading aggressively in the Near East, posing a threat of incursion to Europe and Asia. Due to cross-protection within the Capripoxvirus genus, sheep pox virus (SPPV) vaccines have been widely used for cattle against lumpy skin disease virus (LSDV). In the Middle East and the Horn of Africa these vaccines have been associated with incomplete protection and adverse reactions in cattle post-vaccination. The present study confirms that the real identity of the commonly used Kenyan sheep and goat pox vaccine virus (KSGP) O-240 is not SPPV but is actually LSDV. The low level attenuation of this virus is likely to be not sufficient for safe use in cattle, causing clinical disease in vaccinated animals. In addition, Isiolo and Kedong goat pox strains, capable of infecting sheep, goats and cattle are identified for potential use as broad-spectrum vaccine candidates against all capripox diseases.

    Aim of this study is to evaluate new and controversially discussed indications for determining the thyroglobulin (Tg) level in different thyroid diseases to support routine diagnostics. Methods: The following groups were included: 250 healthy subjects without goiter, 50 persons with diffuse goiter, 161 patients with multinodular goiter devoid of functional disorder (108 of them underwent surgery, in 17 cases carcinomas were detected), 60 hyperthyroid patients with autonomously functioning nodular goiter, 150 patients with Hashimoto's thyroiditis and 30 hyperthyroid patients with Graves' disease. Results: The upper limit of the normal range of the Tg level was calculated as 30 ng Tg/ml. The evaluation of the collective with diffuse goiter showed that the figure of the Tg level can be expected in a similar magnitude as the thyroid volume in milliliters. Nodular tissue led to far higher Tg values then presumed when considering the respective thyroidvolume, with a rather high variance. A formula for a rough prediction of the Tg levels in nodular goiters is described. In ten out of 17 cases with thyroid carcinoma, the Tg was lower than estimated with thyroid and nodular volumes, but two patients showed a Tg exceeding 1000 ng/ml. The collective with functional autonomy had a significantly higher average Tg level than a matched euthyroid group being under suppressive levothyroxine substitution. However, due to the high variance of the Tg values, the autonomy could not consistently be predicted with the Tg level in individual cases. The patients with Hashimoto's thyroiditis showed slightly decreased Tg levels. In Graves' disease, a significantly higher average Tg level was observed compared with a matched group with diffuse goiter, but 47% of all Tg values were still in the normal range (<30 ng/ml). Conclusion: Elevated Tg levels indicate a high probability of thyroid diseases, such as malignancy, autonomy or Graves' disease. However, as low Tg

    The discovery of pathogenic mutations in inherited skin diseases represents one of the major landmarks of late 20th century molecular genetics. Mutation data can provide accurate diagnoses, improve genetic counseling, help define disease mechanisms, establish disease models, and provide a basis for translational research and testing of novel therapeutics. The process of detecting disease mutations, however, has not always been straightforward. Traditional approaches using genetic linkage or candidate gene analysis have often been limited, costly, and slow to yield new insights, but the advent of next-generation sequencing (NGS) technologies has altered the landscape of current gene discovery and mutation detection approaches.

    Psoriasis is a frequent, inflammatory disease of skin and joints with considerable morbidity. Here we report that in psoriatic lesions, epidermal keratinocytes have decreased expression of JunB, a gene localized in the psoriasis susceptibility region PSORS6. Likewise, inducible epidermal deletion of JunB and its functional companion c-Jun in adult mice leads (within two weeks) to a phenotype resembling the histological and molecular hallmarks of psoriasis, including arthritic lesions. In contrast to the skin phenotype, the development of arthritic lesions requires T and B cells and signalling through tumour necrosis factor receptor 1 (TNFR1). Prior to the disease onset, two chemotactic proteins (S100A8 and S100A9) previously mapped to the psoriasis susceptibility region PSORS4, are strongly induced in mutant keratinocytes in vivo and in vitro. We propose that the abrogation of JunB/activator protein 1 (AP-1) in keratinocytes triggers chemokine/cytokine expression, which recruits neutrophils and macrophages to the epidermis thereby contributing to the phenotypic changes observed in psoriasis. Thus, these data support the hypothesis that epidermal alterations are sufficient to initiate both skin lesions and arthritis in psoriasis.

    Epstein-Barr virus (EBV)-associated T- or natural killer (NK)-cell lymphoproliferative disease (LPD) is a heterogeneous group of disorders characterized by chronic proliferation of EBV-infected lymphocytes. Patients may present with severe skin manifestations, including hypersensitivity to mosquito bites (HMB) and hydroa vacciniforme (HV)-like eruption, which are characterized by blister formation and necrotic ulceration. Skin biopsy specimens show inflammatory reactions comprising EBV-infected lymphocytes. However, blister fluids have not been fully assessed in patients with this disease. Blister fluids were collected from three patients with EBV-associated LPD: two with HMB and one with HV. Immunophenotyping of blister lymphocytes and measurement of tumor necrosis factor (TNF)-α in blister fluids were performed. The patients with HMB and HV exhibited markedly increased percentages of NK and γδ T cells, respectively, in both peripheral blood and blister fluids. These NK and γδ T cells strongly expressed the activation marker human leukocyte antigen-DR and were considered to be cellular targets of EBV infections. TNF-α was highly elevated in all blister fluids. Severe local skin reactions of EBV-associated LPD may be associated with infiltrating EBV-infected lymphocytes and a high TNF-α concentration in blister fluids. © 2018 Japanese Dermatological Association.

    Periodical monitoring of renal function, specifically for subjects with history of diabetic or hypertension would prevent them from entering into chronic kidney disease (CKD) condition. The recent increase in numbers may be due to food habits or lack of physical exercise, necessitates a rapid kidney function monitoring system. Presently, it is determined by evaluating glomerular filtration rate (GFR) that is mainly dependent on serum creatinine value and demographic parameters and ethnic value. Attempted here is to develop ethnic parameter based on skin texture for every individual. This value when used in GFR computation, the results are much agreeable with GFR obtained through standard modification of diet in renal disease and CKD epidemiology collaboration equations. Once correlation between CKD and skin texture is established, classification tool using artificial neural network is built to categorise CKD level based on demographic values and parameter obtained through skin texture (without using creatinine). This network when tested gives almost at par results with the network that is trained with demographic and creatinine values. The results of this Letter demonstrate the possibility of non-invasively determining kidney function and hence for making a device that would readily assess the kidney function even at home.

    Acne is a chronic inflammatory disease of the sebaceous-pilosebaceous unit. Interestingly, inflammation can be detected by histopathological examination and immuohistochemical analysis even in the apparently non-inflammatory acneic lesions, such as comedones. In the last years, it has been clearly demonstrated that acne development is linked to the combination of predisposing genetic factors and environmental triggers, among which a prominent role is played by the follicular colonization by Propionibacterium acnes (P. acnes). P. acnes displays several activities able to promote the development of acne skin lesions, including the promotion of follicular hyperkeratinisation, the induction of sebogenesis, and the stimulation of an inflammatory response by the secretion of proinflammatory molecules and by the activation of innate immunity, that is followed by a P. acnes-specific adaptive immune response. In addition, P. acnes-independent inflammation mediated by androgens or by a neurogenic activation, followed by the secretion in the skin of pro-inflammatory neuropeptides, can occur in acne lesions. In conclusion, acne can be considered as a model of immune-mediated chronic inflammatory skin disease, characterized by an innate immune response that is not able to control P. acnes followed by a Th1-mediated adaptive immune response, that becomes self-maintaining independently from P. acnes itself.

    Idelalisib is a selective inhibitor of the delta isoform of phosphatidylinositol 3-kinase which was approved by the United States Federal Drug Administration in 2014 for the treatment of relapsed chronic lymphocytic leukemia and indolent non-Hodgkin lymphoma. Drug-induced injury of the gastrointestinal tract is a relatively frequent but usually under-recognized disease entity. We report the case of a 56-year-old male with a history of relapsed follicular lymphoma status post allogenic bone marrow transplant who developed severe diarrhea with a skin eruption mimicking graft-versus-host disease (GVHD) 6 months after starting idelalisib. He underwent a colonoscopy demonstrating a grossly normal-appearing colon and terminal ileum. Biopsies taken during the procedure revealed mild active ileitis, colitis, and proctitis with frequent epithelial apoptosis, and focal intra-epithelial lymphocytosis. Skin biopsies revealed sub-acute spongiotic dermatitis suggestive of either contact dermatitis or an eczematous drug reaction. Symptoms were attributed to idelalisib given their resolution with withdrawal of the drug in conjunction with the skin and colonic biopsies. High clinical suspicion and awareness of the histological features of idelalisib-associated colitis is important to distinguish it from potential mimickers such as GVHD and infectious colitis.

    This review highlights some of the research advances in anaphylaxis; hypersensitivity reactions to foods, drugs, and insects; and allergic skin diseases that were reported in the Journal in 2011. Food allergy appears to be increasing in prevalence and carries a strong economic burden. Risk factors can include dietary ones, such as deficiency of vitamin D and timing of complementary foods, and genetic factors, such as filaggrin loss-of-function mutations. Novel mechanisms underlying food allergy include the role of invariant natural killer T cells and influences of dietary components, such as isoflavones. Among numerous preclinical and clinical treatment studies, promising observations include the efficacy of sublingual and oral immunotherapy, a Chinese herbal remedy showing promising in vitro results, the potential immunotherapeutic effects of having children ingest foods with baked-in milk if they tolerate it, and the use of anti-IgE with or without concomitant immunotherapy. Studies of allergic skin diseases, anaphylaxis, and hypersensitivity to drugs and insect venom are elucidating cellular mechanisms, improved diagnostics, and potential targets for future treatment. The role of skin barrier abnormalities, as well as the modulatory effects of the innate and adaptive immune responses, are major areas of investigation.

    Chronic graft-versus-host disease (cGVHD) is a frequent and potentially life-threatening complication of allogeneic hematopoietic stem cell transplantation (HCT) and commonly affects the skin, resulting in distressing patient morbidity. The percentage of involved body surface area (BSA) is commonly used for diagnosing and scoring the severity of cGVHD. However, the segmentation of the involved BSA from patient whole body serial photography is challenging because (1) it is difficult to design traditional segmentation method that rely on hand crafted features as the appearance of cGVHD lesions can be drastically different from patient to patient; (2) to the best of our knowledge, currently there is no publicavailable labelled image set of cGVHD skin for training deep networks to segment the involved BSA. In this preliminary study we create a small labelled image set of skin cGVHD, and we explore the possibility to use a fully convolutional neural network (FCN) to segment the skin lesion in the images. We use a commercial stereoscopic Vectra H1 camera (Canfield Scientific) to acquire 400 3D photographs of 17 cGVHD patients aged between 22 and 72. A rotational data augmentation process is then applied, which rotates the 3D photos through 10 predefined angles, producing one 2D projection image at each position. This results in 4000 2D images that constitute our cGVHD image set. A FCN model is trained and tested using our images. We show that our method achieves encouraging results for segmenting cGVHD skin lesion in photographic images.

    Full Text Available Abstract Background The skin is chronically exposed to endogenous and environmental pro-oxidant agents, leading to the harmful generation of reactive oxygen species. Antioxidant is vital substances which possess the ability to protect the body from damage cause by free radicals induce oxidative stress. Alpinia zerumbet, a traditionally important economic plant in Okinawa, contains several interesting bioactive constituents and possesses health promoting properties. In this regard, we carried out to test the inhibitory effect of crude extracts and isolated compounds from A. zerumbet on antioxidant and skin diseases-related enzymes. Methods The antioxidant activities were examined by DPPH, ABTS and PMS-NADH radical scavenging. Collagenase, elastase, hyaluronidase and tyrosinase were designed for enzymatic activities to investigate the inhibitory properties of test samples using a continuous spectrophotometric assay. The inhibitory capacity of test samples was presented at half maximal inhibitory concentration (IC50. Results The results showed that aqueous extract of the rhizome was found to have greater inhibitory effects than the others on both of antioxidant and skin diseases-related enzymes. Furthermore, 5,6-dehydrokawain (DK, dihydro-5,6-dehydrokawain (DDK and 8(17,12-labdadiene-15,16-dial (labdadiene, isolated from rhizome, were tested for antioxidant and enzyme inhibitions. We found that DK showed higher inhibitory activities on DPPH, ABTS and PMS-NADH scavenging (IC50 = 122.14 ± 1.40, 110.08 ± 3.34 and 127.78 ± 4.75 μg/ml, respectively. It also had stronger inhibitory activities against collagenase, elastase, hyaluronidase and tyrosinase (IC50 = 24.93 ± 0.97, 19.41 ± 0.61, 19.48 ± 0.24 and 76.67 ± 0.50 μg/ml, respectively than DDK and labdadiene. Conclusion Our results indicate that the rhizome aqueous extract proved to be the source of bioactive compounds against enzymes responsible for

    While occupational exposure to respirable silica is known to lead to lung disease, most notably silicosis, its association with chronic kidney disease is unclear. This review explores the association between occupational exposure to respirable silica and chronic non-malignant renal disease such as glomerulonephritis. The evidence has been collected and compiled. Possible sources of bias are thoroughly discussed. Cohort studies with silica exposure and case-control studies of renal disease were searched in PubMed until January 2015. Two authors independently abstracted data; any disagreement was resolved by consulting a third reviewer. A meta-analysis was performed to evaluate the association to silica exposure. A total of 23 cohort and four case-control studies were included in the analysis. The meta-analysis of cohort studies yielded elevated overall SMRs for renal disease. Some studies, however, included dose-response analyses, most of which did not show a positive trend. The approaches and results of the case-control studies were very heterogeneous. While the studies of cohorts exposed to silica found elevated SMRs for renal disease, no clear evidence of a dose-response relationship emerged. The elevated risk may be attributed to diagnostic and methodological issues. In order to permit a reliable estimation of a possible causal link, exposed cohorts should be monitored for renal disease, as the information from mortality studies is hardly reliable in this field.

    Spray cryotherapy (SCT) was initially developed for gastroenterology (GI) endoscopic use in the esophagus. In some institutions where a device has been utilized by GI, transition to use in the airways by pulmonologists and thoracic surgeons occurred. Significant differences exist, however, in the techniques for safely using SCT in the airways. We describe the early experience at Walter Reed National Military Medical Center from 2011 to 2013 using SCT in patients with malignant airway disease and the evolution of our current techniques and clinical practice patterns for SCT use in patients. In November 2013 enrollment began in a multi-institutional prospective SCT registry in which we are still enrolling and will be reported on separately. Twenty-seven patients that underwent 80 procedures (2.96 procedures/patient). The average age was 63 years with a range of 20 to 87 years old. The average Eastern Cooperative Oncology Group (ECOG) status was 1.26. All malignancies were advanced stage disease. All procedures were performed in the central airways. Other modalities were used in combination with SCT in 31 (39%) of procedures. Additionally 45 of the 80 (56%) procedures were performed in proximity to a silicone, hybrid, or metal stent. Three complications occurred out of the 80 procedures. All three were transient hypoxia that limited continued SCT treatments. These patients were all discharged from the bronchoscopy recovery room to their pre-surgical state. SCT can be safely used for treatment of malignant airway tumor (MAT) in the airways. Understanding passive venting of the nitrogen gas produced as the liquid nitrogen changes to gas is important for safe use of the device. Complications can be minimized by adopting strict protocols to maximize passive venting and to allow for adequate oxygenation in between sprays.

    The therapy of chronic skin diseases often requires several applications of creams or ointments per day. This is inconvenient to the patients and frequently leads to poor acceptance and compliance. We therefore developed oil-in-oil-emulsions that deliver the active pharmaceutical ingredient (API) to the skin over a prolonged period of time. In this study, we compare the permeation of the API from a conventional formulation to its permeation from an oil-in-oil-emulsion under infinite and finite dosing. Furthermore, we evaluate the substantivity of the formulations. Our results show that the permeation from oil-in-oil-emulsions is constant over a prolonged time and that the emulsions show significantly higher substantivity than conventional formulations. Because of that, the treatment intervals can be extended substantially and compliance can be increased. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association.

    1. Conservation managers rely on accurate estimates of disease parameters, such as pathogen prevalence and infection intensity, to assess disease status of a host population. However, these disease metrics may be biased if low-level infection intensities are missed by sampling methods or laboratory diagnostic tests. These false negatives underestimate pathogen prevalence and overestimate mean infection intensity of infected individuals. 2. Our objectives were two-fold. First, we quantified false negative error rates of Batrachochytrium dendrobatidis on non-invasive skin swabs collected from an amphibian community in El Copé, Panama. We swabbed amphibians twice in sequence, and we used a recently developed hierarchical Bayesian estimator to assess disease status of the population. Second, we developed a novel hierarchical Bayesian model to simultaneously account for imperfect pathogen detection from field sampling and laboratory diagnostic testing. We evaluated the performance of the model using simulations and varying sampling design to quantify the magnitude of bias in estimates of pathogen prevalence and infection intensity. 3. We show that Bd detection probability from skin swabs was related to host infection intensity, where Bd infections information in advance, we advocate that the most cautious approach is to assume all errors are possible and to accommodate them by adjusting sampling designs. The modeling framework presented here improves the accuracy in estimating pathogen prevalence and infection intensity.

  1. Vimentin may reflect areas of pathologic involvement in biopsies from patients with autoimmune skin diseases

    Full Text Available Introduction: Autoimmune bullous skin diseases (ABDs represent a group of disorders of the skin and mucosa commonly associated with deposits of immunoglobulins, complement and fibrinogen, and usually directed against distinct adhesion molecules. After studing these diseases for many years, we noted alterations not only between the cells junctions of the epidermis and/or the dermal/epidermal junction, but also in dermal skin appendageal structures and in mesenchymal tissue around the blisters. Based on our findings, we wanted to determine if the observed patterns of autoimmunity correlated with cutaneous vimentin expression. Materials and Methods: Archival biopsies previously diagnosed with ABDs by clinical, hematoxylin and eosin (H&E and direct and/or immunofluorescence data were stained with antibodies directed against vimentin via immunohistochemistry (IHC. We tested 30 patients affected by endemic pemphigus, 30 controls from the endemic area, and 15 normal controls. We also tested 30 biopsies from patients with bullous pemphigoid (BP, 20 with pemphigus vulgaris (PV, 8 with pemphigus foliaceus, 14 with dermatitis herpetiformis (DH and 3 with Senear-Usher syndrome. Results: The H&E, DIF and vimentin patterns of positivity in the different ABDs confirmed that vimentin was compartmentalized around areas of dermal inflammation, around skin appendages and in epidermal, dermal and mesenchymal cell junction areas. Conclusion: Vimentin may be a useful tool for highlighting patterns of microenvironmental tissue alteration in multiple ABDs. The vimentin staining pattern observed was analogous to that we have previously described for proteases and protease inhibitors in patients affected by ABDs, expanding the concept that the autoimmune process extends beyond cell junctions.

    Peeling skin diseases (PSD) refer to a group of rare autosomal recessive dermatosis which are characterized by spontaneous, continual peeling of the skin. Three different clinical pictures can be distinguished: Inflammatory PSD also referred to as peeling skin syndrome (PSS) type B, non-inflammatory PSD also referred to as PSS type A, and localized forms i.e. acral type PSS. To characterize the clinical and histopathological features of PSD in Turkey. We retrospectively reviewed the medical records and clinical photographs of patients who were given diagnosis of PSD and conducted histopathological evaluation of skin biopsies to identify the site of cleavage. Also we evaluated the cases including age, gender, age onset, clinical and histological findings, family history, associated disorders and PSD type. Twenty-one patients with PSD were seen at Gulhane School of Medicine in Ankara between the years 1994 and 2010 in this retrospective study. All patients were men. Their ages were between 20 and 26 years (22.44±2.30, Mean age±SD). Of the patients, eight cases (40%) were type A, eight cases (40%) were type B, and five cases (20%) were acral type PSS. Eleven cases (52%) had parental consanguinity. Keratoderma, cheilitis, keratosis pilaris, melanonichia, clubbing, hyperhidrosis, onychodystrophy were observed in eight cases as an accompanying disorder. In this case series, PSD occurred rarely and also showed generally mild course of disease in Turkey and most likely related to consanguineous of marriages. Future investigations on PSD will contribute to our progressing alternative targets for pathogenesis-based therapy. © 2011 The Authors.

    Skin diseases are a common reason for consulting a GP. This regular occurrence happens despite most GPs' lack of knowledge and training in skin disease. We aimed to explore different diagnostic approaches of GPs in patients presenting with a dermatological problem. In addition, we aimed to identify strategies used by GPs to handle diagnostic uncertainty in these patients. We conducted interviews (20-40 minutes) with 14 GPs using a semi-structured guideline. Recalling encounters with patients with skin disease, GPs described their individual diagnostic strategies. Interviews were taped and transcribed verbatim. Qualitative analysis was conducted by two independent raters using a deductive-inductive approach. We identified several aspects of a complex decision-making process in GPs' diagnostic management of patients with dermatological problems. In the general diagnostic workup, GPs used a broad spectrum of different strategies such as spot diagnosis, stepwise refinement, pattern recognition trigger or test of treatment. GPs reduced diagnostic uncertainty through the identification of red flags, the application of the test of time, therapeutic trials and asking for further advice, including patient referral. GPs encounter a broad range of dermatological problems in their daily work using a variety of strategies in the workup of these patients. However, in a significant number of patients, there remains diagnostic uncertainty that is mainly reduced by specialist referral. Regular training in the diagnosis and treatment of common dermatological diseases should be offered to all GPs. © The Author 2015. Published by Oxford University Press. All rights reserved.

    Full Text Available Abstract Background In Greece where primary health care services are not fully developed, patients with simple or minor conditions have to attend to hospitals to be treated. We analysed the data of patients with cutaneous disorders attending the tertiary referral hospital on the Island of Crete, with the aim to identify the most common conditions that patients complain of, in order to define the areas where the education of General Practitioners in Dermatology must focus. Methods All patients attending the Dermatology ambulatory office in the Emergency Department of the University General Hospital of Heraklion from January 2003 to December 2003 were included in this retrospective analysis. The medical records of the patients (history, physical examination and laboratory investigations were analysed to ascertain the diagnosis and the management of cases. All patients were evaluated by qualified dermatologists. Results A total of 3715 patients attended the Dermatology Clinic. Most patients were young adults in the age group 21–40 years (38.4%, and the male to female ratio was 1 to 1.2. Allergic skin diseases, mostly dermatitis and urticaria (35.7% were the most common for attendance, followed by infectious diseases (26.1% and insect bites (10.2%. Inflammatory and autoimmune disorders accounted for 7.9% of the cases. Pruritus of unknown origin was diagnosed in 6.3% of patients. Skin tumors were detected in 2.7%. The management of the vast majority of cases (85.0% consisted of advice with or without a prescription, while only 4.8% of patients required admission. Conclusion Allergic and infectious skin diseases were the most common cutaneous diseases in patients attending this tertiary University hospital, while the management of most patients did not require specialised care. On the basis of the present data, the training of primary health care providers in Dermatology should emphasize these common conditions, with the aim of improving primary

    This was an Australasian Bone Marrow Transplant Recipient Registry (ABMTRR)-based retrospective study assessing the outcome of Fludarabine Melphalan (FluMel) reduced-intensity conditioning between 1998 and 2008. Median follow-up was 3.4 years. There were 344 patients with a median age of 54 years (18-68). In all, 234 patients had myeloid malignancies, with AML (n=166) being the commonest indication. There were 110 lymphoid patients with non-hodgkins lymphoma (NHL) (n=64) the main indication. TRM at day 100 was 14% with no significant difference between the groups. OS and disease-free survival (DFS) were similar between myeloid and lymphoid patients (57 and 50% at 3 years, respectively). There was no difference in cumulative incidence of relapse or GVHD between groups. Multivariate analysis revealed four significant adverse risk factors for DFS: donor other than HLA-identical sibling donor, not in remission at transplant, previous autologous transplant and recipient CMV positive. Chronic GVHD was associated with improved DFS in multivariate analysis predominantly due to a marked reduction in relapse (HR:0.44, P=0.003). This study confirms that FluMel provides durable and equivalent remissions in both myeloid and lymphoid malignancies. Disease stage and chronic GVHD remain important determinants of outcome for FluMel allografting.

    Full Text Available Pediatric psycho-oncology within psycho-oncology is a highly developed scientific discipline in the world, both at the level of basic research and the development of theoretical concepts and at the practical level, which refers to the creation and implementation of various models of psychosocial support to children and young people who are suffering from various malignant diseases and their families during all stages of the demanding oncology treatment. One of the models of psychosocial support for children are workshops, as a form of group psychological treatment in which children and young people who are in distress, crisis, shock and even trauma, acquire a new positive experience and which provides new insights and knowledge to empower and boost the quality of life for overcoming severe malignant disease and treatment through meaningful games, all of which leads to overcoming the 'downtime' and regression and encouraging further psychological development. The outcome of workshop activities are various products (drawings, photographs, videos, posters, written material, but also positive feelings and behaviours in children and adolescents. The main objectives of introducing psychological workshops at the department of pediatric hematology-oncology in our community are, on the one hand, to provide professional counselling and support to children and young people during hospitalization and, on the other, to introduce a standard psychological procedure and quality psychological practice of group psychological counselling for sick children and young people in the hospital environment.

    Full Text Available Cancer incidence is progressively increasing in parallel with an increase in the rate of cancer survivors with the help of advanced treatment modalities. By the year 2010, it is estimated that one in every 250 persons will have survived a childhood malignancy. The increased rates of survival bring about complications related to reproductive health. Cytotoxic treatments due to chemo- and radiotherapy or bone marrow transplantation suppress or irreversibly harm not only female ovarian reserve but also male testicular sperm production. In this review, cryopreservation of gametes and gonads with fertility preservation options and indications prior to cancer treatments are discussed.

Because of the immunosuppressive properties of tumor necrosis factor (TNF-alpha (TNF-α antagonists, it is plausible that these biologics may increase the risk of the occurrence of malignancies or the reactivation of latent malignancies. TNF-α antagonists have gained momentum in the field of dermatology for treating rheumatoid arthritis and psoriasis, and they have revolutionized the treatment of other inflammatory autoimmune diseases such as refractory Crohn's disease. However, there is accumulating evidence that TNF-α inhibitors slightly increase the risk of cancer, including malignant melanoma (MM. The authors herein report the case of a 54-year-old female patient who developed a primary MM during treatment with adalimumab for severe Crohn’s disease resistant to successive medical therapies. The patient had been receiving this TNF-α blocker therapy for 3 years before the occurrence of MM. After wide surgical excision of the lesion and staging (based on Breslow thickness and Clark level, evaluation with a whole-body computed tomography scan was negative for metastatic disease. The long duration of the adalimumab therapy and the patient's lack of a predisposition to skin cancer suggest an association between anti-TNF-α drugs and melanocytic proliferation. The authors also review the literature on the potential association between anti-TNF regimens and the occurrence of malignancies such as melanocytic proliferations. There is a substantial hypothetical link between anti-TNF-α regimens such as adalimumab and the potential for cancers

    Epidemiological studies to determine the burden of skin diseases are important for proper health care planning. The purpose of this study was to find the pattern of skin diseases in our patients attending university-affiliated dermatologic clinics in the Qassim region.We conducted a prospective study of all Saudi patients attending the Qassim University Medical College-affiliated dermatology clinics of the Ministry of Health for a period of 12 months from 1 March 2008 to 28 February 2009.The study included 3051 patients comprising 1786 (58.5%) males and 1265 (41.5%) females. Males outnumbered females (P<.05) (male-to-female ratio, 1.4:1). The mean age (standard error of the mean) of the patients was 25.3 (0.27) years. About 71% of the patients were between 5 and 34 years of age. The top five skin diseases were eczema/ dermatitis (19.5%), viral infections (16.6%), pilosebaceous disorders (14.4%), pigmentary lesions (11.2%) and hair disorders (7.6%). The major disorder in males was viral skin infections (20.0%), while eczema/dermatitis (20.7%) constituted the most prevalent skin disease in females. Seasonal variations were recorded in cases of pigmentary lesions, papulosquamous disorders and protozoal infections.Infectious skin diseases, eczema/dermatitis, pilosebaceous disorders, pigmentary lesions and hair disorders ranked as the top five skin diseases. Appropriate training programs for diagnosing and managing common skin diseases should be initiated for primary health care physicians and other general practitioners so as to decrease referrals to dermatology clinics (Author).

    Inflammation is a homeostatic mechanism aiming to maintain tissue integrity. The underlying immunological mechanisms and the interrelationship between ionizing radiation and inflammation are complex and multifactorial on cellular and chemical levels. On the one hand, radiation with single doses exceeding 1 Gy might initiate inflammatory reactions and thereby impact on tumor development. On the other hand, radiation is capable of attenuating an established inflammatory process, which is clinically used for the treatment of inflammatory and degenerative diseases with low-dose radiotherapy (single dose modulates inflammatory events in benign inflammatory and in malign diseases. A special focus is set on the role of tumor infiltrating lymphocytes and macrophages as biomarkers to predict treatment response and anti-tumor immunity and on mechanisms implicated in the anti-inflammatory effects of low-dose radiation therapy.

    Clonal B-cell proliferation is a frequent manifestation of Gaucher disease - a sphingolipidosis associated with a high risk of multiple myeloma and non-Hodgkin lymphoma. Gaucher disease is caused by genetic deficiency of acid β-glucosidase, the natural substrates of which (β-d-glucosylceramide and β-d-glucosylsphingosine) accumulate, principally in macrophages. Mice with inducible deficiency of β-glucosidase [Gba(tm1Karl/tm1Karl)Tg(MX1-cre)1Cgn/0] serve as an authentic model of human Gaucher disease; we have recently reported clonal B-cell proliferation accompanied by monoclonal serum paraproteins and cognate tumours in these animals. To explore the relationship between B-cell malignancy and the biochemical defect, we treated Gaucher mice with eliglustat tartrate (GENZ 112638), a potent and selective inhibitor of the first committed step in glycosphingolipid biosynthesis. Twenty-two Gaucher mice received 300 mg/kg of GENZ 112638 daily for 3-10 months from 6 weeks of age. Plasma concentrations of β-d-glucosylceramide and the unacylated glycosphingolipid, β-d-glucosylsphingosine, declined. After administration of GENZ 112638 to Gaucher mice for 3-10 months, serum paraproteins were not detected and there was a striking reduction in the malignant lymphoproliferation: neither lymphomas nor plasmacytomas were found in animals that had received the investigational agent. In contrast, 14 out of 60 Gaucher mice without GENZ 112638 treatment developed these tumours; monoclonal paraproteins were detected in plasma from 18 of the 44 age-matched mice with Gaucher disease that had not received GENZ 112638. Long-term inhibition of glycosphingolipid biosynthesis suppresses the development of spontaneous B-cell lymphoma and myeloma in Gaucher mice.

    Full Text Available Lumpy skin disease virus (LSDV and sheeppox virus (SPV have a considerable economic impact on the cattle and small ruminant industry. They are listed in group A of contagious disease by the World Organization for Animal Health (OIE. This study addressed molecular characterisation of first LSDV outbreak and an endemic SPV in Kurdistan region of Iraq based on P32 gene. The results indicated that P32 gene can be successfully used for diagnosis of LSDV. The phylogenic and molecular analysis showed that there may be a new LSDV isolate circulating in Kurdistan which uniquely shared the same characteristic amino acid sequence with SPV and GPV, leucine at amino acid position 51 in P32 gene as well as few genetically distinct SPV causing pox disease in Kurdistan sheep. This study provided sequence information of P32 gene for several LSDV isolates, which positively affects the epidemiological study of Capripoxvirus

    Acid sphingomyelinase deficiency (ASMD) is a lysosomal storage disorder characterized by the pathologic accumulation of sphingomyelin in multiple cells types, and occurs most prominently within the liver, spleen and lungs, leading to significant clinical disease. Seventeen ASMD patients underwent a liver biopsy during baseline screening for a Phase 1 trial of recombinant human acid sphingomyelinase (rhASM) in adults with Niemann-Pick disease type B. Eleven of the 17 were enrolled in the trial and each received a single dose of rhASM and underwent a repeat liver biopsy on Day 14. Biopsies were evaluated for fibrosis, sphingomyelin accumulation and macrophage infiltration by light and electron microscopy. When present, fibrosis was periportal and pericellular, predominantly surrounding affected Kupffer cells. Two baseline biopsies exhibited frank cirrhosis. Sphingomyelin was localized to isolated Kupffer cells in mildly affected biopsies and was present in both Kupffer cells and hepatocytes in more severely affected cases. Morphometric quantification of sphingomyelin storage in liver biopsies ranged from 4–44% of the microscopic field. Skin biopsies were also performed at baseline and Day 14 in order to compare the sphingomyelin distribution in a peripheral tissue to that of liver. Sphingomyelin storage was present at lower levels in multiple cell types of the skin, including dermal fibroblasts, macrophages, vascular endothelial cells, vascular smooth muscle cells and Schwann cells. This Phase 1 trial of rhASM in adults with ASMD provided a unique opportunity for a prospective assessment of hepatic and skin pathology in this rare disease and their potential usage as pharmacodynamic biomarkers.

    Patient-reported outcome measures are increasingly utilized in dermatology to assess the impact of skin disease on quality of life. Despite recognition of the influence of skin disease on intimate relationships, an instrument to assess intimacy has not been developed. The objective of this study was to create the dermatologic intimacy scale (DIS) and administer the prototype to a patient population. A group of healthcare providers at the University of California San Francisco created the DIS prototype. A total of 1676 psoriasis patients of an online community were invited to complete a cross-sectional survey including demographic information, DIS, body surface area (BSA) and anatomical involvement. A total of 1109 patients completed the survey in its entirety. Patients with moderate-to-severe psoriasis (BSA ≥3%) had a higher DIS score overall and for each individual question than patients with mild disease (BSA intimacy. Interpretation is limited by patient response rate, as patients with or without intimacy issues may be more or less likely to respond. Further analysis is necessary for validation and interpretation.

    People with chronic venous disease are at high risk for developing venous leg ulcers. Inflammation is posited as a pathological factor for this chronic condition as evidenced by persistently elevated skin temperature. As part of a larger trial to test the effects of a cooling regimen on leg ulcer prevention, the objective of this preliminary study was to evaluate the first 30 days of intense daily cooling. Compared to a placebo control cuff, a gel cuff applied to the most severely affected lower leg skin for 30 min daily showed no statistically significant differences between temperatures taken in the home at baseline compared to those measured at the 1 month follow up visit. There were also no differences in temperatures noted between the two groups, although the temperatures in the treatment group were lower 30 min after treatment, an indication of adherence. There was no discernable decrease or increase in temperature at a given time point during the 30 day treatment period compared to the control group. It may be better to have patients monitor skin temperature on a daily basis and then apply the cuff as necessary, rather than requiring daily cooling based on baseline measurement. This "prn" approach may provide a sufficient cooling milieu to prevent escalation of inflammation and thwart ulcer occurrence or recurrence. Clinical trials registration #NCT01509599.

    eLife digest Herpes simplex virus 2 (or HSV-2) infects millions of people worldwide and is the leading cause of genital diseases. The virus initially infects skin cells, but then spreads to nerve cells where it persists for life. Often, the virus remains in a dormant state for long periods of time and does not cause any symptoms. However, HSV-2 can periodically re-activate, leading to repeated infections; this can be life-threatening in patients who suffer from a weak immune system. There is ...

    To compare the use of live interactive teledermatology versus conventional face-to-face consultation in long-term, institutionalised psychiatric patients with chronic skin diseases. All institutionalised psychiatric patients at the Institute of Mental Health with follow-up appointments at the National Skin Centre were assessed for eligibility and invited to participate. Recruited patients were first seen by a dermatologist via videoconferencing, and then by another dermatologist in person, within 1 week. Clinical outcome measures were then assessed by a third independent dermatologist. The following outcome measures were assessed for each paired patient visit: inter-physician clinical assessment, diagnosis, management plan, adverse events and total patient turnaround time (PTAT) for each consultation. There were a total of 13 patients (mean age, 64.6 years; range 44-80) with 27 patient visits. All were male patients with chronic schizophrenia. The predominant skin condition was chronic eczema and its variants (62%), followed by cutaneous amyloidosis (23%) and psoriasis (15%). The level of complete and partial agreement between the teledermatology and face-to-face consultation was 100% for history-taking and physical examination and 96% for the investigations, diagnosis, management plan and the treatment prescribed. The PTAT for teledermatology was 23 min, compared to 240 min for face-to-face consultations. No adverse events were reported. Teledermatology was as effective as face-to-face consultation and reduced the PTAT by 90%, resulting in increased patient convenience, operational efficiency and reduced manpower need. Our study supports the safe and cost-effective use of teledermatology for the follow-up of chronic skin conditions in psychiatric patients. © 2015 The Australasian College of Dermatologists.

    Squamous cell carcinoma antigens 1 and 2 (SCCA1 and 2, SERPIN B3 and B4), members of the ovalbumin serpin (ov-serpin)/clade B serpin family, were originally discovered as tumor-specific antigens and are used as tumor markers for various kinds of squamous cell carcinomas. Recently, our understanding of the underlying mechanisms of how SCCA1/2 enhance tumor growth has greatly increased. Moreover, it has been shown that SCCA1/2 are involved in the pathogenesis of several inflammatory diseases: asthma, psoriasis, and atopic dermatitis (AD). IL-22 and IL-17, signature cytokines of type 17 inflammation, as well as IL-4 and IL-13, signature cytokines of type 2 inflammation, both of which are positively correlated with the pathogenesis of psoriasis and allergic diseases, respectively, can induce expression of SCCA1/2 in airway epithelial cells and/or keratinocytes, leading to high expression of SCCA1/2 in these diseases. Based on these findings, several trials have been performed to examine the potential of applying SCCA1/2 to biomarkers for these diseases. The findings show that SCCA2 is useful to aid diagnosis, estimate clinical severity and disease type, and assess responses to treatment in psoriasis and AD. These results suggest that SCCA2 has emerged as a novel biomarker for skin inflammatory diseases.

    Intelligent Diagnostic Assistant can be used for complicated diagnosis of skin diseases, which are among the most common causes of disability. The aim of this study was to design and implement a computerized intelligent diagnostic assistant for complicated skin diseases through C5's Algorithm. An applied-developmental study was done in 2015. Knowledge base was developed based on interviews with dermatologists through questionnaires and checklists. Knowledge representation was obtained from the train data in the database using Excel Microsoft Office. Clementine Software and C5's Algorithms were applied to draw the decision tree. Analysis of test accuracy was performed based on rules extracted using inference chains. The rules extracted from the decision tree were entered into the CLIPS programming environment and the intelligent diagnostic assistant was designed then. The rules were defined using forward chaining inference technique and were entered into Clips programming environment as RULE. The accuracy and error rates obtained in the training phase from the decision tree were 99.56% and 0.44%, respectively. The accuracy of the decision tree was 98% and the error was 2% in the test phase. Intelligent diagnostic assistant can be used as a reliable system with high accuracy, sensitivity, specificity, and agreement.

This was an exploratory, retrospective, descriptive study of 146 patients from 22 rheumatology departments. A number of clinical features (young male, nocturnal sweats, generalized pruritus, protracted fever, central or peripheral lymphadenopathy) and laboratory test abnormalities (evidence of severe inflammation) considerably increased the likelihood of Hodgkin's disease rather than malignant lymphoma. The diagnosis of bony involvement requires multidisciplinary studies of tumor specimens. (authors). 4 figs., 7 tabs., 71 refs

    Contact curietherapy with 32 P is conducted in sixty-one patients affected with keratoma senile (34), leukoplakia vulvae (15), chronic eczema (10), Bowen's disease (1) and Queyrat's disease (1). A contact technique with applicator is used. The single skin dose amounts to 5 Gy/hour. Irradiation rhythm is: alternating 5 consecutive days with 2 days rest period. The total dose per course leading to a permanent therapeutic effect (3 years) varies in the range 35 to 100 Gy/h. Optimal results are recorded in 42% of cases, very good - in 52%, and satisfactory - in 6%. A wider application of the method in hematological practice is recommended because of the low radiation exposure and absence of complications. 12 refs. (orig.)

    For nearly two decades, dermatology has associated with psychology to find a better way to care for dermatology conditions. A scientific trend called psychosomatics is creating a link between dermatology and psychology. The purpose of this article was to examine two concepts closely linked to psychodermatology (life events and tendency to complain) and to emphasize the difference between factors playing a role in the onset of certain skin diseases (psoriasis, alopecia areata, benign tumors, eczema). We found that psoriasis patients have a greater tendency to complain than people with the other disease. This point to the importance of taking emotions into account when studying psoriasis. We also found that life events play a role in the onset of psoriasis and alopecia areata. Moreover, these events were anterior by more than 12 months in alopecia patients. We propose exploring emotions in psoriasis patients and life events over the prior year in alopecia areata patients.

    We have shown previously that skin perfusion is reduced in patients with diabetes mellitus (DM). Patients with diabetes and with chronic kidney disease (CKD) stage 5 were having advanced microangiopathy. In this cross-sectional study, we measured skin blood flow in DM and non-DM patients on dialysis to assess whether any differences exist in skin perfusion in those 2 groups of patients. A total of 25 patients with DM (aged 59.9 +/- 2.2 years) and 24 patients with non-DM CKD stage 5 (44.6 +/- 2.9 years) on hemodialysis (HD) were studied. Ten healthy subjects (37 +/- 4.3 years) were used as a control group. Skin blood flow (SBF) was measured using Vasamedic Model 403B laser Doppler device (Vasamedics Inc., St. Paul, MN) in a standardized way at the plantar and dorsal surface of the finger and toe and at the pretibial surface of the leg at 2 different local skin temperatures of 35 degrees C and 44 degrees C. Laboratory biochemical data were collected at the time of SBF study. The SBF measured at 35 degrees C was lower in the patients with DM on dialysis as compared with healthy subjects and non-DM dialysis patients. The SBF response to the increase in temperature of the probe to 44 degrees C was 70% to 80% lower in DM patients as compared with healthy subjects and non-DM patients. However, non-DM subjects who displayed SBF similar to control subjects at 35 degrees C, had impaired response in SBF at 44 degrees C as well. Patients with lower serum albumin exhibited lower SBF even after adjustment for age. SBF is impaired in patients with stage 5 CKD on HD, particularly in those with DM as a cause of CKD. SBF negatively correlated with age and albumin (nutritional status) in DM and non-DM patients with stage 5 CKD on HD. Measurement of SBF can be useful in the evaluation of vasculopathy in CKD population and can potentially be used for assessment of vascular response during specific clinical intervention.

    The early medical complications of Chernobyl accident include post radiation disease, which were diagnosed in 134 subjects affected by ionizing radiation. 28 persons died during the first 100 days after the event. The increase occurrence of coronary heart disease, endocrine, haematological, dermatological and other diseases were observed after disaster in the contaminated territories. We also discussed the impact of ionizing radiation from Chernobyl accident on pregnancy and congenital defects occurrence. Changes following the Chernobyl accident, as the inhabitants migration from contaminated regions, political and economic conversions, led to depression, anxiety, and even to '' epidemic '' of mental diseases. Increased suicide rate, car accidents, alcohol and drug abuse have been observed in this population. Nowadays vegetative neurosis is more often diagnosed in Ukrainian children. Epidemiological studies were conducted on the ionising radiation effect on the health and on the dose of received radiation after Chernobyl accident face numerous problems as the absence of reliable data regarding diseases in the contaminated territories.(authors)

    2017-01-01

    Full Text Available ErbB proteins overexpression, in both normal and mutated forms, is associated with invasive forms of cancer prone to metastasis and with stronger antiapoptotic mechanisms and therefore more challenging to treat. Downstream effectors of ErbB receptors mediating these phenotypic traits include MAPK, STAT, and PI3K/AKT/mTOR pathways. Various phytochemical compounds were studied for their large number of biological effects including anticancer activity. Among these compounds, epigallocatechin-3-gallate (EGCG, the main catechin from green tea leaves, and curcumin, component of the curry powder, constituted the object of numerous studies. Both compounds were shown to act directly either on ErbB expression, or on their downstream signaling molecules. In this paper we aim to review the involvement of ErbB proteins in cancer as well as the biologic activity of EGCG and curcumin in ErbB expressing and overexpressing malignancies. The problems arising in the administration of the two compounds due to their reduced bioavailability when orally administered, as well as the progress made in this field, from using novel formulations to improved dosing regimens or improved synthetic analogs, are also discussed.

    To develop a classification tree for the preoperative prediction of benign versus malignant disease in patients with small renal masses. This is a retrospective study including 395 consecutive patients who underwent surgical treatment for a renal mass classification tree to predict the risk of having a benign renal mass preoperatively was developed using recursive partitioning analysis for repeated measures outcomes. Age, sex, volume on preoperative imaging, tumor location (central/peripheral), degree of endophytic component (1%-100%), and tumor axis position were used as potential predictors to develop the model. Forty-five patients (11.4%) were found to have a benign mass postoperatively. A classification tree has been developed which can predict the risk of benign disease with an accuracy of 88.9% (95% CI: 85.3 to 91.8). The significant prognostic factors in the classification tree are tumor volume, degree of endophytic component and symptoms at diagnosis. As an example of its utilization, a renal mass with a volume of classification tree to predict the risk of benign disease in small renal masses has been developed to aid the clinician when deciding on treatment strategies for small renal masses.

    Four to 20% positive findings were found in a review of 1913 excretory urographics. Possibly relevant findings were 20% in patients referred for infectious disease, 10% in hypertensive disease, 6% in hematuria and 4% in neoplasms. Urography influenced treatment mainly in the 2 groups with few positive findings. The costs for positive findings may be acceptable in patients with hematuria or suspicion of neoplasms, but are too high in the other groups. Until ultrasonography can replace intravenous urography as the first screening method in upper urinary tract disease, the patient selection for urography in infectious and hypertensive disease should be improved.
