    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.

    Clinical manifestations of pericardial disease may precede other signs and symptoms associated with systemic lupus erythematosus. Although pericardial effusion is one of the most common cardiac problems in patients with systemic lupus erythematosus, haemodynamically significant effusions manifesting as cardiac tamponade are rare and require prompt diagnosis and treatment.

    Advancement in correction or palliation of congenital cardiac lesions has greatly improved the lifespan of congenital heart disease patients, resulting in a rapidly growing adult congenital heart disease (ACHD) population. As this group has increased in number and age, emerging science has highlighted the systemic nature of ACHD. Providers caring for these patients are tasked with long-term management of multiple neurologic, pulmonary, hepatic, renal, and endocrine manifestations that arise as syndromic associations with congenital heart defects or as sequelae of primary structural or hemodynamic abnormalities. In this review, we outline the current understanding and recent research into these extra-cardiac manifestations. Copyright © 2016 Elsevier Inc. All rights reserved.

    BACKGROUND: Nephrogenic systemic fibrosis (NSF) is a serious disease that occurs in patients with severe renal disease and is believed to be caused by gadolinium-containing contrast agents. A detailed description of the late skin manifestations of NSF is important to help dermatologists...... and nephrologists recognize the disease. OBSERVATIONS: We studied 17 patients with NSF late in the disease. All patients showed epidermal atrophy and hairlessness of the affected regions, primarily the lower legs. Affected areas were symmetrically distributed and hyperpigmented in most cases. Eleven patients showed......: This descriptive case series of patients with NSF gives a detailed clinical picture of the skin manifestations late in the disease. It demonstrates that the clinical picture in the late stage has a varied presentation and that NSF has a significant effect on the quality of life....

    According to Hansen's contact rule, the digestive system should be considered as the main shock organ, yet in food allergy, this is not the case. Very often specific food triggers clinical manifestations not involving the digestive system; that is, reactions are manifested either in the respiratory system, as asthma or rhinitis, or in the skin. In these cases the BALT (broncho-alveolar lymphoid tissue) and GALT (gastrointestinal lymphoid tissue) units play a basic role in the sensitizations. The purpose of this study was to determine the most frequent skin manifestations of food allergy among children, and the most frequently involved foods. We also thought it interesting to evaluate the diagnostic reliability of the different standard immunological parameters utilized by the study team in food allergy. All patients underwent intracutaneous tests with 12 groups of the most frequent food allergens, as well as serum IgE, antigen-specific IgE against foods, and antigen-specific histamine release tests. Antigen-specific IgG4 determination was performed in some cases. The results obtained confirmed previous studies, the most common manifestations being: angioedema (48%), followed by urticaria (31%) and atopic dermatitis (21%). Regarding the frequency of sensitization to different food allergens, in mono- or polisensitization, fish and egg stand out in our environment. Certain food allergens are more frequently responsible for specific skin manifestations. Thus, for fish sensitization, the most frequent skin manifestation is atopic dermatitis (50%); for egg sensitization, angioedema is the most frequent skin manifestation (50%); and for milk, urticaria (50%). Finally, and in agreement with previous works regarding the diagnostic reliability of in vitro techniques, we found that the histamine release test offered the highest percentage of diagnostic reliability. Only for sensitization to milk proteins did antigen-specific IgE demonstrate higher reliability. Once again, we

    Background. Neoplastic pericarditis can be presented as acute pericarditis, pericardial effusion, effusive constrictive pericarditis or cardiac tamponade. For the majority of patients, a clinical manifestation of neoplastic pericarditis is absent or remains unrecognised during their life. Case report: A 69-year-old non-smoking woman with acute dyspnoea, tachycardia, jugular venous distension, hepatomegaly and right side pleural effusion was presented in the emergency department. The roentgen picture of the chest confirmed pleural effusion and revealed enlarged heart. An emergency echocardiogram established the diagnosis of cardiac tamponade. The patient improved immediately after the therapeutic pericardiocentesis. Cytology of pericardial fluid confirmed malignant glandular cells, consistent with metastatic adenocarcinoma. A computed chest tomography showed a right side pleural effusion and a solitary round lesion in the right lower lobe of the lung. Bronchoscopy with fundoscopic lung biopsy and brushing revealed adenocarcinoma. Cardiac tamponade as the initial manifestation of malignancy is rare and rare is also malignant pericardial effusion due the adenocarcinoma of the lung in a non-smoking woman. The presented patient had one of the longest survival reported in literature despite a limited life expectancy regardless of the treatment in the patient presented with neoplastic pericarditis.

    Skin manifestations are common clinical features among HIV positive patients. The aim of this study was to document skin manifestations and their relationships with CD4 cell counts among HIV positive patients in Sanandaj. This was a descriptive study. The patients were examined for skin disorders by a dermatologist and CD4 counts were obtained from the patient's medical records. Independent samples T test were used for data analysis. In this study 66 (94.3%) patients had at least one skin problem. Fungal infections were the most common cause. The eight most common types of mucocutaneous problems were gingivitis, pallor, itching, photosensitivity, seborrheic dermatitis, candidiasis, folliculitis and tinea versicolor. The most common manifestation was gingivitis. Mean CD4 cell counts were lower in individuals with viral and bacterial skin diseases (P <0.05). The results of this study indicated that skin problems were common among HIV positive patients. Patients with advanced stages of skin disorders had relatively lower CD4 counts. Therefore examination of skin is recommended for all HIV positive patients for early detection of skin disorders, as early diagnosis and management of dermatologic problems will improve the quality of life in HIV positive patients.

    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.

    A 44-year-old female with a diagnosis of mitochondrial myopathy, encephalopathy and stroke-like episodes (MELAS) syndrome had progressive left ventricular hypertrophy (LVH) on echocardiogram. A Holter monitor demonstrated episodes of non-sustained atrial tachycardia, a finding not been previously described in this population. This unique case of MELAS syndrome demonstrates the known associated cardiac manifestation of LVH and the new finding of atrial tachycardia which may represent the potential for subclinical arrhythmia in this population.

    Objective To examine if psoriatic patients can achieve a weight loss to the same extent as non-psoriatic patients To describe the effect of weight loss on the cutaneous manifestations. Conclusion Patients with psoriasis achieved a weight loss, similar to non-psoriatic patients, of 12...... % of their body weight following calorie restriction for 12 weeks. Taken together with recent literature the findings suggest that weight loss has a potential to reduce skin manifestations. Weight loss might also attenuate the increased cardiovascular and diabetes risks posed by obese psoriatric patients....

    Granulomatous slack skin is a very rare subtype of T-cell cutaneous lymphoma, characterized by the slow development of cutaneous sagging, especially on flexural areas. Its behavior is indolent and the treatment, in the majority of cases, disappointing. We report a 54-year-old black patient with granulomatous slack skin, who at the beginning of the investigation showed intense xeroderma and generalized lymph node enlargement. The diagnosis was established based on histopathologic findings long before the disease's characteristic clinical presentation appeared. During the twelve years of follow-up, the clinical manifestation evolved to marked skin looseness, most predominant in flexural regions, illustrating the clinical hallmark of granulomatous slack skin, long after first histological abnormalities were observed.

    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.

  18. Non-cardiac manifestations of Marfan syndrome

    Science.gov (United States)

    2017-01-01

    Because of the widespread distribution of fibrillin 1 in the body, Marfan syndrome (MFS) affects virtually every system. The expression of this single dominantly inherited gene is variable within a family, and between families. There is some genotype-phenotype correlation which is helpful in guiding long-term prognosis, and management. In general gene mutations have been reported in clusters, with those having mainly ocular manifestations occurring in exons 1 to 15 of this 65-exon gene; those causing cardiac problems often involving cysteine replacement in a calcium binding EGF-like sequence; the most severe mutations occurring in exons 25–32, causing neonatal MFS diagnosed at birth, and severe enough to cause death frequently before the age of 2. Other correlations will certainly be found in future. This condition is progressive, and the manifestations unfold according to age. For example, if the lens is going to dislocate this usually occurs by age 10; scoliosis usually presents itself between the ages of 8 and 15; height should be monitored carefully between the onset of puberty and cessation of growth approximately age 17 or 18. Holistic care should be offered by one doctor who oversees the patient’s welfare. This should be a paediatrician, paediatric cardiologist, or general practitioner in the case of an affected child. Thereafter, the physician in charge of the most seriously affected system should be aware that other systems need to be managed through a referral network. PMID:29270372

    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.

    Full Text Available Context: Sulfur mustard (SM was used during the Iraq-Iran war (1980–1988. Exposed veterans continue to suffer from its ocular, skin, and respiratory complications. Objective: We aimed to evaluate associations between early (at the time of acute exposure and decades later skin manifestations in individuals with severe ophthalmologic complications secondary to sulfur mustard exposure. Materials and methods: One hundred forty-nine veterans with severe ocular injuries were evaluated for acute and chronic skin complications. Logistic regression models were used to examine the associations between early and late skin manifestations. Results: Late skin complaints were observed in nearly all survivors who had early skin lesions (131 out of 137; 95.62%. Seven out of 12 patients (58.33% who did not have early skin lesions ultimately developed late skin complications. There was a significant relationship between the presence of lesions at the time of exposure and developing late skin complaints (two-sided Fisher's exact test, OR = 15.59, p < 0.001. There was an association between having at least one early skin lesion and occurrence of late skin complications. Survivors with blisters at the time of chemical exposure were more likely to complain of itching (95% CI: 3.63–25.97, p < 0.001, burning (OR = 11.16; 95% CI: 2.97–41.89, p < 0.001, pigmentation changes (OR = 10.17; 95% CI: 2.54–40.75, p = 0.001, dryness (OR = 6.71, 95% CI: 1.22–37.01, p = 0.03 or cherry angioma (OR = 2.59; 95% CI:1.21–5.55, p = 0.01 during the late phase. Using multivariate logistic models, early blisters remained significantly associated with latent skin complaints. Of note, the genitalia and great flexure areas were the most involved anatomical sites for both early and late skin lesions in SM exposed survivors. Conclusion: According to this study, the presence of blisters at the time of exposure to SM is the most important predictor of developing

    Markers of operation room (OR) efficiency in cardiac surgery are focused on "knife to skin" and "start time tardiness." These do not evaluate the middle and later parts of the cardiac surgical pathway. The purpose of this analysis was to evaluate knife to skin time as an efficiency marker in cardiac surgery. We looked at knife to skin time, procedure time, and transfer times in the cardiac operational pathway for their correlation with predefined indices of operational efficiency (Index of Operation Efficiency - InOE, Surgical Index of Operational Efficiency - sInOE). A regression analysis was performed to test the goodness of fit of the regression curves estimated for InOE relative to the times on the operational pathway. The mean knife to skin time was 90.6 ± 13 minutes (23% of total OR time). The mean procedure time was 282 ± 123 minutes (71% of total OR time). Utilization efficiencies were highest for aortic valve replacement and coronary artery bypass grafting and least for complex aortic procedures. There were no significant procedure-specific or team-specific differences for standard procedures. Procedure times correlated the strongest with InOE (r = -0.98, p knife to skin is not as strong an indicator of efficiency. A statistically significant linear dependence on InOE was observed with "procedure times" only. Procedure times are a better marker of OR efficiency than knife to skin in cardiac cases. Strategies to increase OR utilization and efficiency should address procedure times in addition to knife to skin times. © 2015 Wiley Periodicals, Inc.

  2. Cutaneous manifestations of primary immunodeficiency

    Full Text Available Primary immunodeficiency diseases (PIDs are a group of rare, chronic disorders with deficient or malfunctioning immune system. It commonly affects the hematopoietic system, with skin the second most affected organ. Skin involvement is observed in half of pediatric PID cases and often precedes the final diagnosis. Skin infections and eczemas are the two most common manifestations in PID.[1] Skin manifestations associated with PIDs can be of infectious and noninfectious causes. Common noninfectious causes are eczema, erythroderma, cutaneous granulomas, dysplasia, vasculitis, and telangiectasia. It is important to be aware of skin manifestations in pediatric patients as early detection of PID may aid in the management of serious immunologic conditions and prevent associated morbidity and mortality.

    Sternal wound infection after cardiac surgery is a serious complication. Various perioperative strategies, including plastic adhesive drapes, are used to reduce bacterial contamination of surgical wounds. To compare plastic adhesive drape to bare skin regarding bacterial growth in wound and time to recolonization of the adjacent skin intraoperatively, in cardiac surgery patients. This single-blinded randomized controlled trial (May 2010 to May 2011) included 140 patients scheduled for cardiac surgery via median sternotomy. The patients were randomly allocated to the adhesive drape (chest covered with plastic adhesive drape) or bare skin group. Bacterial samples were taken preoperatively and intraoperatively every hour during surgery until skin closure. Disinfection with 0.5% chlorhexidine solution in 70% alcohol decreased coagulase-negative staphylococci (CoNS), while the proportion colonized with Propionibacterium acnes was not significantly reduced and was still present in more than 50% of skin samples. P. acnes was significantly more common in men than in women. Progressive bacterial recolonization of the skin occurred within 2-3 h. At 120 min there were significantly more positive cultures in the adhesive drape group versus bare skin group for P. acnes (63% vs 44%; P = 0.034) and for CoNS (45% vs 24%; P = 0.013). The only statistically significant difference in bacterial growth in the surgical wound was higher proportion of CoNS at the end of surgery in the adhesive drape group (14.7% vs 4.4%; P = 0.044). Plastic adhesive drape does not reduce bacterial recolonization. P. acnes colonized men more frequently, and was not decreased by disinfection with chlorhexidine solution in alcohol.

    In this study, we evaluated MR imaging findings of skin tumors and categorized them into four types: (1) discrete mass lesions of the dermis and epidermis, (2) mass lesions of the subcutis with or without abutment to the skin, (3) diffuse or localized skin thickening without a true mass, and (4) a skin mass with bone destruction. The categorization of MR images may be useful in the differential diagnosis of skin tumors. (orig.)

    Full Text Available Although previously rare, catheter-related bloodstream infection caused by rapidly growing mycobacteria is now increasingly encountered, especially among cancer patients who have catheters implanted for chemotherapy treatments. A 73-year-old female patient with acute myeloid leukemia (AML had Mycobacterium abscessus bacteremia with manifestations of multiple skin nodules, pneumonia, and mediastinal lymphadenopathy 4 months after the implantation of a peripherally inserted central catheter (PICC for the delivery of chemotherapy. The catheter-related M. abscessus bacteremia was confirmed by positive blood cultures of specimens drawn from a PICC line and a peripheral vein. She defervesced with the administration of meropenem, amikacin, levofloxacin, clarithromycin, and by the removal of PICC. Her fever subsided for 3 months with the disappearance of skin and lung lesions; however, she died of AML relapse. Bacteremia and skin infection caused by M. abscessus can be detected by culture and pathological examinations and should be considered in leukemia patients with a PICC. With appropriate laboratory diagnosis, M. abscessus bacteremia with disseminated infections can improve with catheter removal and combination antimicrobial therapy.

    The aim of this study was to investigate association between pulmonary and skin manifestations in a large group of patients with primary antiphospholipid syndrome (PAPS) as well as their connection with antiphospholipid antibodies. Our prospective study comprises of 390 patients with primary APS. Antiphospholipid antibody (aPL) analysis included detection of aCL (IgG/IgM), ß2GPI (IgG/IgM) and LA. Distinct pulmonary and skin associations were determined, as well as their associations with aPL. In PAPS patients the presence of LA was more common in PTE (p=0.005) and in pulmonary microthrombosis (p=0.003). We revealed statistical significance considering the presence of aCL IgM and pulmonary microthrombosis (p=0.05). Skin ulcerations correlated with positive titres aCL IgM and ß2 GPI IgM (p=0.03 and 0.04, respectively), while pseudovasculitis correlated with positive titres ß2 GPI IgM (p=0.02). PAPS patients were more more likely to develop pulmonary thromboembolisam if they had livedo reticularis (p=0.005), skin ulcerations (p=0.007), pseudovasculitic lesions (p=0.01), superficial cutaneous necrosis (p=0.005), and digital gangrene (p=0.02). Patients were also more prone to pulmonary microthrombosis if they already had livedo reticularis (p=0.03), skin ulcerations (p=0.007), pseudovasculitic lesions (p=0.05), superficial cutaneous necrosis (p=0.006), and digital gangrene (p=0.02). There is strong link between some pulmonary and skin manifestations in PAPS patients, suggesting complexity and evolutionary nature of APS. The presence of skin manifestations may be a high risk factor for several types of serious pulmonary manifestations in PAPS. Certain aPL types are associated with distinct pulmonary and skin manifestation, suggesting their predictive role.

    Cardiac tamponade is a medical emergency condition. Rapid diagnosis and determination of the etiology with epidemiologic consideration may lead to earlier treatment and improved survival. Occasionally, the etiology may be clearly related to a recognized underlying disease, but the possibility of unrelated etiologies should be considered. Pericarditis tuberculosis, a rare manifestation of extrapulmonary tuberculosis in a non-HIV patient, has to be deliberate as one of the etiology, especially in the endemic area. Here, we report a case of 28 years old male with β thalassemia major presented with excessive exertion breathlessness progressing to orthopnea. Sign of cardiac tamponade was identified from echocardiography which showed large pericardial effusion with swinging heart and right atrial systolic collapse. Pericardiocentesis was performed immediately, drained 870 ml of hemorrhagic fluid from inserted pigtail. The patient was treated with the anti-tuberculosis regimen and oral corticosteroid after real-time polymerase chain reaction of Mycobacterium tuberculosis positivity in pericardial fluid. MRI T2 confirmed no haemosiderosis in patient’s heart. After treatment, the patient responded well and showed clinical improvement.

    The early and correct diagnosis of cardiac implantable electronic device (CIED) infections is critical given that early aggressive treatment with complete removal of the system along with antimicrobial therapy dramatically improves outcomes. Pocket infection manifested by local signs of inflammation is the most common form of CIED infections. Conditions mimicking pocket infection have been described in the literature. These include various types of malignancy and rarely allergic reactions/contact dermatitis to pacemaker compounds. We aimed to describe skin lesions and disorders over the pocket area that mimic CIED infection. We present a series of 5 cases with skin lesions that mimic pocket infection. We document these cases with corresponding photographs. Most of them have not been described in this setting. We report the following cases of conditions that proved not to be CIED infection: One case of superficial cellulitis, one case of herpes zoster over the pocket area, one case of spontaneous bruising over the pocket a long time after implantation in a patient taking oral anticoagulation, and 2 cases of contact dermatitis due to prolonged postoperative application of povidone iodine. All cases had favorable outcome after conservative treatment and no CIED infection was developed during follow-up. Clinicians should be aware of rare conditions that mimic CIED infection. Incorrect diagnosis of these disorders may falsely lead to CIED extraction. This article is protected by copyright. All rights reserved. This article is protected by copyright. All rights reserved.

    Juvenile xanthogranuloma is a rare histiocytic disorder of childhood mainly affecting skin and rarely deep soft tissues and viscera. We report a 2-month-old infant who presented with respiratory distress secondary to a large pericardial effusion associated with an epicardial mass. Excisional biopsy was performed and the mass was diagnosed as juvenile xanthogranuloma. The child is well without evidence of disease 8 months following the excision. The corresponding literature on juvenile xanthogranuloma with cardiac manifestations is reviewed. © 2012 Wiley Periodicals, Inc.

    Full Text Available The frequency of pericardial involvement in Systemic Sclerosis (SSc is high on autoptic or echocardiographic studies, but the clinical recognition of pericarditis with or without effusion is rare. We describe a case of a 71-year-old female with no previous history of heart disease, who presented with a large pericardial effusion and tamponade that required pericardial drain. She had suffered from Raynaud’s phenomenon since 25 years. Six weeks after hospital discharge she complained of skin hardening on left leg. Pericardial tamponade is a very rare manifestation of SSc and occurs both early or late in the course of the disease, but in our case it preceded the recognition of scleroderma. We have only identified two other cases of pericardial effusion preceding cutaneous involvement in scleroderma.

    Full Text Available Background: Diabetes mellitus affects individuals of all ages and socioeconomic status. Skin is affected by the acute metabolic derangements as well as by chronic degenerative complications of diabetes. Aims: To evaluate the prevalence of skin manifestations in patients with diabetes mellitus. To analyze the prevalence and pattern of skin disorders among diabetic patients from this region of Western Himalayas. Materials and Methods: One hundred consecutive patients with the diagnosis of diabetes mellitus and having skin lesions, either attending the diabetic clinic or admitted in medical wards were included in this study. Results: The common skin disorders were: x0 erosis (44%, diabetic dermopathy (36%, skin tags (32%, cutaneous infections (31%, and seborrheic keratosis (30%. Conclusion: Skin is involved in diabetes quite often and the manifestations are numerous. High prevalence of xerosis in our diabetic population is perhaps due to cold and dry climatic conditions in the region for most of the time in the year.

    Systemic lupus erythematosus (SLE) is a multiorgan autoimmune disease of unknown etiology with many clinical manifestations. The skin is one of the target organs most variably affected by the disease. The American College of Rheumatology (ACR) established 11 criteria as a classificatory instrument to operationalise the definition of SLE in clinical trials. They were not intended to be used to diagnose individuals and do not do well in that capacity. Cutaneous lesions account for four of these 11 revised criteria of SLE. Skin lesions in patients with lupus may be specific or nonspecific. This paper covers the SLE-specific cutaneous changes: malar rash, discoid rash, photosensitivity, and oral mucosal lesions as well as SLE nonspecific skin manifestations, their pathophysiology, and management. A deeper thorough understanding of the cutaneous manifestations of SLE is essential for diagnosis, prognosis, and efficient management. Thus, dermatologists should cooperate with other specialties to provide optimal care of SLE patient. PMID:22888407

    Blood to skin recirculation could play a role in the pathogenesis of psoriasis. To investigate this possibility we dissected the phenotype of circulating T cells in psoriasis patients, calculated the correlation the clinical parameters of the disease and performed a parallel bioinformatics analysis of gene expression data in psoriatic skin. We found that circulating CCR6 + CD4 + T EM and T EFF cells significantly correlated with systemic inflammation. Conversely, the percentage of CXCR3 + CD4 + T EM cells negatively correlated with the severity of the cutaneous disease. Importantly CLA + CD4 + T CM cells expressing CCR6 + or CCR4 + CXCR3 + negatively correlated with psoriasis severity suggesting recruitment to the skin compartment. This assumption was reinforced by gene expression data showing marked increase of CCR7 and CLA-encoding gene SELPLG expression in psoriatic skin and strong association of their expression. The data enlightens a role for CD4 + T cells trafficking between blood and skin in cutaneous and systemic manifestations of psoriasis. Copyright © 2017 Elsevier Inc. All rights reserved.

  15. Biological Rhythms in the Skin

    Full Text Available Circadian rhythms, ≈24 h oscillations in behavior and physiology, are reflected in all cells of the body and function to optimize cellular functions and meet environmental challenges associated with the solar day. This multi-oscillatory network is entrained by the master pacemaker located in the suprachiasmatic nucleus (SCN of the hypothalamus, which directs an organism’s rhythmic expression of physiological functions and behavior via a hierarchical system. This system has been highly conserved throughout evolution and uses transcriptional–translational autoregulatory loops. This master clock, following environmental cues, regulates an organism’s sleep pattern, body temperature, cardiac activity and blood pressure, hormone secretion, oxygen consumption and metabolic rate. Mammalian peripheral clocks and clock gene expression have recently been discovered and are present in all nucleated cells in our body. Like other essential organ of the body, the skin also has cycles that are informed by this master regulator. In addition, skin cells have peripheral clocks that can function autonomously. First described in 2000 for skin, this review summarizes some important aspects of a rapidly growing body of research in circadian and ultradian (an oscillation that repeats multiple times during a 24 h period cutaneous rhythms, including clock mechanisms, functional manifestations, and stimuli that entrain or disrupt normal cycling. Some specific relationships between disrupted clock signaling and consequences to skin health are discussed in more depth in the other invited articles in this IJMS issue on Sleep, Circadian Rhythm and Skin.

    Skin involvement is reported during primary parvovirus B19 infection in adults. We sought to describe the cutaneous presentations associated with parvovirus B19 primary infection in adults. We conducted a descriptive, retrospective, multicenter study. The patients included (>18 years old) had well-established primary infections with parvovirus B19. Twenty-nine patients were identified between 1992 and 2013 (17 women, 12 men). The elementary dermatologic lesions were mostly erythematous (86%) and often purpuric (69%). Pruritus was reported in 48% of cases. The rash predominated on the legs (93%), trunk (55%), and arms (45%), with a lower frequency of facial involvement (20%). Four different but sometimes overlapping patterns were identified (45%): exanthema, which was reticulated and annular in some cases (80%); the gloves-and-socks pattern (24%); the periflexural pattern (28%); and palpable purpura (24%). The limitations of this study were its retrospective design and possible recruitment bias in tertiary care centers. Our findings suggest that primary parvovirus B19 infection is associated with polymorphous skin manifestations with 4 predominant, sometimes overlapping, patterns. The acral or periflexural distribution of the rash and the presence of purpuric or annular/reticulate lesions are highly suggestive of parvovirus B19 infection.

    Children with complex congenital heart diseases often require repeated cardiac catheterization; however, children are more radiosensitive than adults. Therefore, radiation-induced carcinogenesis is an important consideration for children who undergo those procedures. We measured entrance skin doses (ESDs) using radio-photoluminescence dosimeter (RPLD) chips during cardiac catheterization for 15 pediatric patients (median age, 1.92 years; males, n = 9; females, n = 6) with cardiac diseases. Four RPLD chips were placed on the patient's posterior and right side of the chest. Correlations between maximum ESD and dose-area products (DAP), total number of frames, total fluoroscopic time, number of cine runs, cumulative dose at the interventional reference point (IRP), body weight, chest thickness, and height were analyzed. The maximum ESD was 80 ± 59 (mean ± standard deviation) mGy. Maximum ESD closely correlated with both DAP (r = 0.78) and cumulative dose at the IRP (r = 0.82). Maximum ESD for coiling and ballooning tended to be higher than that for ablation, balloon atrial septostomy, and diagnostic procedures. In conclusion, we directly measured ESD using RPLD chips and found that maximum ESD could be estimated in real-time using angiographic parameters, such as DAP and cumulative dose at the IRP. Children requiring repeated catheterizations would be exposed to high radiation levels throughout their lives, although treatment influences radiation dose. Therefore, the radiation dose associated with individual cardiac catheterizations should be analyzed, and the effects of radiation throughout the lives of such patients should be followed. (author)

    2008-07-01

    Hepatitis B Virus (HBV) leads to a number of hepatic complications, from acute to chronic hepatitis, cirrhosis and hepatocellular carcinoma, is a well-established fact. Upcoming clinical research, over the years, associates numerous extrahepatic manifestations during the acute and chronic episodes of hepatitis B with significant morbidity and mortality. A causal relationship between HBV and serious autoimmune disorders has also been observed among certain susceptible vaccine recipients in a defined temporal period following immunization. The cause of these extrahepatic manifestations is generally believed to be immune mediated. The most commonly described include skin rash, arthritis, arthralgia, glomerulonephritis, polyarteritis nodosa, and papular acrodermatitis etc. The serum-sickness like "arthritis-dermatitis" prodrome has also been observed in approximately one-third of patients acquiring HBV infections. Skin manifestations of HBV infection typically present as palpable purpura reported to be caused by chronic HBV, although this association remains controversial. To consider the relationship between HBV and other clinically significant disorders as well as serious autoimmune disorders among certain vaccine recipients is the topic of this review. Variable factors that influence extrahepatic manifestation are discussed, including possible synergy between hepatitis B virus and the immune system.

    In most countries of European Union, legislation requires the determination of the total skin dose received by patients during interventional procedures in order to prevent deterministic damages. Various dose indicators like dose-area product (DAP), cumulative dose (CD) and entrance dose at the patient plane (EFD) are used for patient dosimetry purposes in clinical practice. This study aimed at relating those dose indicators with doses ascribed to the most irradiated areas of the patient skin usually expressed in terms of local maximal skin dose (MSD). The study was performed in two different facilities for two most common cardiac procedures coronary angiography (CA) and percutaneous coronary interventions (PCI). For CA procedures, the registered values of fluoroscopy time, total DAP and MSD were in the range (0.7-27.3) min, (16-317) Gy cm 2 and (43-1507) mGy, respectively, and for interventions, accordingly (2.1-43.6) min, (17-425) Gy cm 2 , (71-1555) mGy. Moreover, for CA procedures, CD and EFD were in the ranges (295-4689) mGy and (121-1768) mGy and for PCI (267-6524) mGy and (68-2279) mGy, respectively. No general and satisfactory correlation was found for safe estimation of MSD. However, results show that the best dose indicator which might serve for rough, preliminary estimation is DAP value. In the study, the appropriate trigger levels were proposed for both facilities. (authors)

    2011-01-01

    Skin tightening describes the treatment of skin laxity via radiofrequency (RF), ultrasound, or light-based devices. Skin laxity on the face is manifested by progressive loss of skin elasticity, loosening of the connective tissue framework, and deepening of skin folds. This results in prominence of submandibular and submental tissues. Genetic factors (chronological aging) and extrinsic factors (ultraviolet radiation) both contribute to skin laxity. There are many RF, ultrasound, and light-based devices directed at treating skin laxity. All of these devices target and heat the dermis to induce collagen contraction. Heating of the dermis causes collagen denaturation and immediate collagen contraction in addition to long-term collagen remodeling. Via RF, light, or ultrasound, these skin tightening devices deliver heat to the dermis to create new collagen and induce skin tightening. This chapter will provide an overview of the various skin tightening devices. Copyright © 2011 S. Karger AG, Basel.

    It has been suggested that extrinsic skin ageing manifests differently in Caucasians versus East Asians. In particular, from previous studies it was concluded that Caucasians are more prone to develop wrinkles, whereas pigment spot formation is the hallmark of extrinsic skin ageing in East Asians. However, these assumptions are based on a very limited number of studies which did not include different East Asian populations. We here compare the manifestation of extrinsic skin ageing signs in German, Japanese and Chinese women by specifically elucidating the age and anatomical site dependence of any potential ethnic difference. In the present study, we assessed skin ageing in N=902 German, N=165 Japanese and N=1260 Chinese women ranging from 30 to 90 years by means of SCINEXA™. Linear regression analysis was used to test for ethnic differences and their age and site dependence adjusted for educational level, sun exposure, smoking and sun protection behaviours. Pigment spots and wrinkles on the face were present among all three ethnic groups and differences were influenced by age and anatomical sites independently of further influencing factors. Pigment spots on the forehead were most pronounced over the whole age range in Chinese and German women and least developed in Japanese. Pigment spots on cheeks were a typical extrinsic skin an ageing sign in the two East Asian populations in all age groups. However, in older German women they reach the same level as observed in the two East Asian populations. In contrast, pigment spots on arms and hands were significantly more pronounced in German women ≥45years of age. Wrinkles were not exclusively a skin an ageing sign of German women, but were also very pronounced in Chinese women on forehead, between the eyebrows and in the crow's feet area. These results corroborate the previous notion that the occurrence of pigments spots and wrinkles is different between Caucasians and East Asians. In addition, this study shows

    Introduction The clinical expression of systemic lupus erythematosus (SLE) is the consequence of endothelial cell damage leading to serious multiple organ dysfunction. The aim of this study was to assess the association between nailfold capillaroscopic changes and disease activity, skin and renal involvement in patients with SLE. Methods Demographic variables, clinical manifestations and laboratory data of 108 patients with SLE were investigated. Nailfold capillaroscopy (NFC) was performed in all patients. Result Morphological changes in NFC were observed in 102 out of 108 (94.4%) SLE patients. Minor changes were found in 33 (30.6%) and major changes in 69 (63.9%) cases. The disease activity was significantly higher in the patients with major changes ( p  0.05), except for the elongated capillary loops, which were seen more often in patients with renal involvement than in patients without it ( p < 0.03). Conclusion The results of the study showed that capillary changes (abnormal capillaroscopy) were very common in patients with SLE, although there were no specific patterns like the ones in scleroderma patients, and some changes may be associated with disease activity, especially in patients with active skin involvement.

A total of forty diagnosed cases of hyperthyroidism constituted the subject material for the study and were evaluated for the presence of any cutaneous manifestation. Results: In our study group of 40 patients, the predominant cutaneous symptom was increased sweating (80%, followed by heat intolerance (42.5%. The predominant cutaneous sign in hyperthyroid patients was increased skin temperature, noticed in 47.5% of patients. This was followed by soft, smooth and velvety skin (37.5%, palmar erythema (35%, fine thin hair (22.5% and hyperpigmentation (10%. Conclusions: The interaction between thyroid gland and skin is very complex. So, dermatologists need to be cognizant of the ways in which these two organs interact.

    Infective endocarditis (IE) is a disease with high morbidity and a mortality rate of 9-30%, even with appropriate diagnosis and therapy. Septic emboli, caused by IE, can affect any organ or tissue in the body with an arterial supply and occur in 12-40% of IE cases. The most common extra-cardiac organ system involved in IE is the central nervous system. Other organs frequently involved are the lungs (especially in right-sided IE), spleen, kidneys, liver, and the musculoskeletal system. In addition, the arterial system itself is susceptible to the development of potentially fatal mycotic aneurysms. As extra-cardiac complications often antedate the clinical diagnosis of IE, it is important that the diagnosis is suggested when characteristic findings are encountered during imaging. In addition, imaging is often used to monitor the extent of complications in patients with a known diagnosis of IE. (orig.)

    Cardiac interventional radiology has lower risks than surgical procedures. This is despite the fact that radiation doses from cardiac intervention procedures are the highest of any commonly performed general X-ray examination. Maximum radiation skin doses (MSDs) should be determined to avoid radiation-associated skin injuries in patients undergoing cardiac intervention procedures. However, real-time evaluation of MSD is unavailable for many cardiac intervention procedures. This review describes methods of determining MSD during cardiac intervention procedures. Currently, in most cardiac intervention procedures, real-time measuring of MSD is not feasible. Thus, we recommend that physicians record the patient's total entrance skin dose, such as the dose at the interventional reference point when it can be monitored, in order to estimate MSD in intervention procedures

    Full Text Available Magnesium is the second most common intracellular cation and serves as an important metabolic cofactor to over 300 enzymatic reactions throughout the human body. Among its various roles, magnesium modulates calcium entry and release from sarcoplasmic reticulum and regulates ATP pumps in myocytes and neurons, thereby regulating cardiac and neuronal excitability. Therefore, deficiency of this essential mineral may result in serious cardiovascular and neurologic derangements. In this case, we present the clinical course of a 76-year-old woman who presented with marked cardiac and neurological signs and symptoms which developed as a result of severe hypomagnesemia. The patient promptly responded to magnesium replacement once the diagnosis was established. We herein discuss the clinical presentation, pathophysiology, diagnosis, and management of severe hypomagnesemia and emphasize the implications of magnesium deficiency in the cardiovascular and central nervous systems. Furthermore, this case highlights the importance of having high vigilance for hypomagnesemia in the appropriate clinical setting.

    Skin metastases from either prostate adenocarcinoma or multiple myeloma rarely occur. We report the case of a 73-year-old man with multiple myeloma who presented with multiple subcutaneous nodules 3 years after his initial diagnosis. Fluorine-18 fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) imaging was suggestive of a concomitant second primary from the prostate. This case highlights not only a rare initial manifestation of prostate cancer, but also the role of 18F-FDG-PET/CT in detecting a clinically unsuspected second malignancy. It potentially corroborates the possible association of both diseases, as has been reported before.

    Full Text Available Background : Systemic lupus erythematosus (SLE is an autoimmune disease with multiorgan involvement. The skin is the second most commonly affected organ. SLE with skin lesions can produce considerable morbidity resulting from painful skin lesions, alopecia, disfigurement, etc. Skin lesions in patients with lupus may be specific (LE specific or may be non specific (LE non specific. Acute cutaneous LE (Lupus specific has a strong association with systemic disease and non-specific skin lesions always indicate disease activity for which patients present to rheumatologists and internists. Therefore, a thorough understanding of the cutaneous manifestations of SLE is essential for most efficient management. Aims: The aims of this study were to evaluate the patterns and prevalence of skin lesions in patients with SLE and to assess the relationship between skin lesions and other systemic involvement. Materials and Methods: At the Department of Rheumatology and Clinical Immunology, IPGME&R in Kolkata, 150 patients with SLE fulfilling the clinical and laboratory criteria of the American Rheumatology Association (updated 1982 were examined and followed-up for cutaneous manifestations between January 2002 and January 2007. Results: Skin lesions were important clinical features. About 45 patients (30% presented with skin lesions although all patients had skin lesions during the follow-up period. Skin changes noted were as follows: Lupus specific lesions: malar rash in 120 patients (80%, photosensitive dermatitis in 75 patients (50%, generalized maculopapular rash in 40 patients (26.67%, discoid rash in 30 patients (20%, subacute cutaneous lupus erythematosus (SCLE in 5 patients (3.34%, lupus profundus in 5 patients (3.34%.

    Deterministic effects have been reported in cardiac interventional procedures. To prevent radiation skin injuries in percutaneous coronary intervention (PCI), it is necessary to measure accurate patient entrance skin dose (ESD) and maximum skin absorbed dose (MSD). We measured the MSD on 62 patients in four facilities by using the Chest-RADIREC system. The correlation between MSD and fluoroscopic time, dose area product (DAP), and cumulative air kerma (AK) showed good results, with the correlation between MSD and AK being the strongest. The regression lines using MSD as an outcome value (y) and AK as predictor variables (x) was y=1.18x (R 2 =0.787). From the linear regression equation, MSD is estimated to be about 1.18 times that of AK in real time. The Japan diagnostic reference levels (DRLs) 2015 for IVR was established by the use of dose rates using acrylic plates (20 cm thick) at the interventional reference point. Preliminary reference levels proposed by International Atomic Energy Agency (IAEA) were provided using DAP. In this study, AK showed good correlation most of all. Hence we think that Japanese DRLs for IVR should reconsider by clinical patients' exposure dose such as AK. (author)

    To determine the percentage of Lyme patients with articular manifestations in NW Spain and to know their evolution and response to treatment. A retrospective study (2006-2013) was performed using medical histories of confirmed cases of Lyme disease showing articular manifestations. Clinical and laboratory characteristics, together with the treatment and evolution of the patients, were analysed. Seventeen out of 108 LD confirmed patients (15.7%) showed articular manifestations. Regarding those 17 patients, 64.7%, 29.4% and 5.9% presented arthritis, arthralgia and bursitis, respectively. The knee was the most affected joint. Articular manifestations were often associated to neurological, dermatological and cardiac pathologies. Otherwise, most patients were in Stage III. The 11.8% of the cases progressed to a recurrent chronic arthritis despite the administration of an appropriate treatment. Lyme disease patients showing articular manifestations should be included in the diagnosis of articular affections in areas of high risk of hard tick bite, in order to establish a suitable and early treatment and to avoid sequels.

    2016-05-01

    Lyme disease (Lyme borreliosis) is a systemic infectious disease that can present in a variety of clinical manifestations. The disease is caused by a group of spirochaetes--Borrelia burgdorferi sensu lato or Lyme borrelia--that are transmitted to humans by the bite of Ixodes ticks. Lyme disease is the most common arthropode-borne infectious disease in many European countries including Germany. Early localized infection is typically manifested by an erythema migrans skin lesion, in rarer cases as a borrelial lymphocytoma. The most common early disseminated manifestation is (early) neuroborreliosis. In adults, neuroborreliosis appears typically as meningoradiculoneuritis. Neuroborreliosis in children, however, is typically manifested by meningitis. In addition, multiple erythema migrans lesions and Lyme carditis occur relatively frequently. The most common manifestation oflate Lyme disease is Lyme arthritis. Early manifestations (and usually also late manifestations) of Lyme disease can be treated successfully by application of suitable antibacterial agents. For the treatment of Lyme disease, doxycycline, certain penicillins such as amoxicillin and some cephalosporins (ceftriaxone, cefotaxime, cefuroxime axetil) are recommended in current guidelines. A major challenge is the treatment of chronic, non-specific disorders, i. e., posttreatment Lyme disease syndrome and "chronic Lyme disease". Prevention of Lyme disease is mainly accomplished by protecting against tick bites. Prophylactic administration of doxycycline after tick bites is generally not recommended in Germany. There is no vaccine available for human beings.

    Hyperkalemia is a common electrolyte abnormality and has well-recognized early electrocardiographic manifestations including PR prolongation and symmetric T wave peaking. With severe increase in serum potassium, dysrhythmias and atrioventricular and bundle branch blocks can be seen on electrocardiogram. Although cardiac arrest is a worrisome consequence of untreated hyperkalemia, rarely does hyperkalemia electrocardiographically manifest as acute ischemia. We present a case of acute renal failure complicated by malignant hyperkalemia and eventual ventricular fibrillation cardiac arrest. Recognition of this disorder was delayed secondary to an initial ECG pattern suggesting an acute ST segment elevation myocardial infarction (STEMI). Emergent coronary angiography performed showed no evidence of coronary artery disease. Pseudo-STEMI patterns are rarely seen in association with acute hyperkalemia and are most commonly described with patient without acute cardiac symptomatology. This is the first such case presenting concurrently with cardiac arrest. A brief review of this rare pseudo-infarct pattern is also given.

    Dengue infection may manifest asymptomatic, dengue fever, dengue hemorrhagic fever, dengue shock syndrome. However, atypical manifestations in other organs have been increasingly reported and called expanded dengue syndrome. One of the cardiac complications in dengue is myocarditis. An 18-year-old woman complains of high fever since 3 days, epistaxis, chest pain, dyspnea, and vomiting. Laboratory examination obtained thrombocytopenia, hemoconcentration, NS1, IgG-IgM dengue positive, CKMB and Troponin- I increase. Electrocardiogram result ischemic anterior-posterior. Echocardiography results hyperechogenic on myocardial suspicious a myocarditis. The patient was diagnosed with acute myocarditis and dengue hemorrhagic fever. Condition improved after five days of treatment. Cardiac complications in dengue are now increasingly observed with the most common case is myocarditis. The main mechanism of dengue myocarditis is still unknown though both direct viral infection and immune mediated damage have been suggested to be the cause of myocardial damage. The low incidence of dengue myocarditis is because it’s asymptomatic and diagnosis is easily missed. Almost all cases of dengue myocarditis are self-limiting and severe myocarditis leading to dilated cardiomyopathy is extremely rare. There have been reported a patient with dengue hemorrhagic fever with manifestation myocarditis. Condition improve with supportive management.

    Full Text Available Cardiac rhabdomyomas are the most comman cardiac tumors in children. They are hamartomatous benign tumors composed of myocytes. They often presents as multiple lesions involving the ventricular cavities. Rhabdomyomas are usually detected in utero by fetal echocardiography. Although patients with cardiac rhabdomyomas are generally asymptomatic these tumors may cause heart failure, severe arrhyhmias and sudden death. Cardiac rhabdomyomas are often associated with tuberosclerosis and they may be the earliest manifestation of tuberosclerosis. Here, we report a newborn infant with antenatally detected cardiac rhabdomyomas associated with tuberosclerosis and we want to emphasize that other diagnostic features of tuberosclerosis should be evaluated in patients with cardiac rhabdomyomas.

    2016-09-01

    Epilepsy is one of the most disabling symptoms of tuberous sclerosis complex (TSC) and is a leading cause of morbidity and mortality in affected individuals. The relationship between systemic disease manifestations and the presence of epilepsy has not been thoroughly investigated. This study utilizes a multicenter TSC Natural History Database including 1,816 individuals to test the hypothesis that systemic disease manifestations of TSC are associated with epilepsy. Univariate analysis was used to identify patient characteristics (e.g., age, gender, race, and TSC mutation status) associated with the presence of epilepsy. Individual logistic regression models were built to examine the association between epilepsy and each candidate systemic or neurologic disease variable, controlling for the patient characteristics found to be significant on univariate analysis. Finally, a multivariable logistic regression model was constructed, using the variables found to be significant on the individual analyses as well as the patient characteristics that were significant on univariate analysis. Nearly 88% of our cohort had a history of epilepsy. After adjusting for age, gender, and TSC mutation status, multiple systemic disease manifestations including cardiac rhabdomyomas (odds ratio [OR] 2.3, 95% confidence interval [CI] 1.3-3.9, p = 0.002), retinal hamartomas (OR 2.1, CI 1.0-4.3, p = 0.04), renal cysts (OR 2.1, CI 1.3-3.4, p = 0.002), renal angiomyolipomas (OR 3.0, CI 1.8-5.1, p epilepsy. In the multivariable logistic regression model, cardiac rhabdomyomas (OR 1.9, CI 1.0-3.5, p = 0.04) remained significantly associated with the presence of epilepsy. The identification of systemic disease manifestations such as cardiac rhabdomyomas that confer a higher risk of epilepsy development in TSC could contribute to disease prognostication and assist in the identification of individuals who may receive maximal benefit from potentially novel, targeted, preventative therapies.

    Full Text Available Background: Thyroid disorders are known to involve all the organ systems of the body, the skin being no exception. The association of thyroid disorders with cutaneous manifestations is complex. Both hypothyroidism and hyperthyroidism are known to cause these changes. Aims: The present study was designed to ascertain the varied cutaneous manifestations of hypothyroidism. Materials and Methods: This study was a hospital based clinical study conducted in collaboration with the Endocrinology Division (Department of Medicine of SMHS Hospital (associated teaching hospital of Government Medical College Srinagar, over a period of one year, from May 2010 to May 2011. Four hundred and sixty consecutive diagnosed cases of hypothyroidism constituted the subject material for the study and were evaluated for the presence of any cutaneous manifestation. Results: In our study group of 460 patients, there were 416 females and 44 male patients. The predominant cutaneous symptom in our hypothyroid patients was dry coarse skin (65.22%, followed by hair loss (42.6% and puffy edema (38.48%. The most common cutaneous sign observed in hypothyroid patients was xerosis (57.17%, followed by diffuse hair loss (46.09%, altered skin texture (31.74%, coarse scalp hair (29.35% and puffy face (28.69%. Conclusions: The interaction between thyroid gland and skin is of profound clinical importance in dermatological practice. So, dermatologists need to be cognizant of the ways in which these two organs interact.

    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.

    Full Text Available The most recent studies have explained almost 2.3 million children are affected with HIV up to the end of 2009. Sub-Saharan Africa is the main region affected by AIDS compare to other parts of the world. Despite providing competent healthcare services to prevent mother-to-child transmission as a main way of infection to a newborn, an estimated 370,000 children were newly infected to HIV in 2009. Skin disorders are common and may even be the first manifestation of HIV in children.The most common skin illnesses are classified in four categories; infectious, inflammatory, neoplastic, and drug related (Highly Active Antiretroviral Therapy. In addition, unusual anatomical sites, disseminated skin lesions, increased frequency and severity, unexplained clinical presentation, rapid onset, and finally treatment failure may be the other specified skin conditions in HIV/AIDS children. CD4 count and viral load are two basic factors playing an important role in terms of type and severity of skin illness. The aim of this review was to show the common and crucial cutaneous findings among HIV/AIDS children via published articles with the same subject.

    Dermatitis herpetiformis (DH) is an itchy blistering skin disease with predilection sites on elbows, knees, and buttocks. Diagnosis is confirmed by showing granular immunoglobulin A deposits in perilesional skin. DH is one manifestation of coeliac disease; the skin symptoms heal with gluten free diet (GFD) and relapse on gluten challenge. Of the first-degree relatives, 5% may be affected by either condition. Tissue transglutaminase (TG2) is the autoantigen in coeliac disease and epidermal transglutaminase (TG3) in DH. Both diseases conditions exhibit TG2-specific autoantibodies in serum and small bowel mucosa; patients with DH have IgA-TG3 in the skin. There are some divergencies between these two phenotypes. One-fourth of DH patients do not have small bowel mucosal villous atrophy, but virtually all have coeliac-type inflammatory changes. The skin symptoms respond slowly to GFD. The incidence of coeliac disease is increasing, whereas the opposite is true for DH. A female predominance is evident in coeliac disease, while DH may be more common in males. Coeliac disease carries the risk of small intestinal T-cell lymphoma; in DH B-cell lymphomas at any site may prevail. Adult coeliac disease carries a slightly increased elevated mortality risk, whereas in DH, the relative mortality rate is significantly decreased. Key messages Dermatitis herpetiformis is a cutaneous manifestation of coeliac disease; both conditions are genetically determined and gluten-dependent. Gastrointestinal symptoms and the degree of villous atrophy are less obvious in dermatitis herpetiformis than in coeliac disease. Both show tissue transglutaminase (TG2) specific autoantibodies in serum and small bowel mucosa. In addition, TG3-targeted IgA antibodies are found in the skin of DH patients Both conditions carry an increased elevated risk of lymphoma, in coeliac disease small intestinal T-cell lymphoma, in dermatitis herpetiformis mainly B-cell lymphoma at various sites.

    Primary immunodeficiencies (PIDs) are a heterogeneous group of rare diseases that result from defects in immune system development and/or function. The clinical manifestations of PIDs are highly variable, but most disorders involve at least an increased susceptibility to infection. Furthermore, cutaneous manifestations are very common in PIDs. As an easily accessible organ, the skin can be crucial for early diagnosis and treatment. This is relevant for preventing significant disease-associated morbidity and mortality. We provide a table that enables the reader to find the possible diseases and corresponding gene defects based on the skin manifestations of the suspected PIDs. To our knowledge, this is the first review that allows the reader to find relevant PIDs and the respective gene defects through solitary or combined skin signs. © 2017 British Association of Dermatologists.

    Full Text Available Background: Chronic renal failure (CRF presents with an array of cutaneous manifestations. Newer changes are being described since the advent of hemodialysis, which prolongs the life expectancy, giving time for these changes to manifest. Aim: The aim of this study was to evaluate the prevalence of dermatologic problems among patients with chronic renal failure (CRF undergoing hemodialysis. Methods: One hundred patients with CRF on hemodialysis were examined for cutaneous changes. Results: Eighty-two per cent patients complained of some skin problem. However, on examination, all patients had at least one skin lesion attributable to CRF. The most prevalent finding was xerosis (79%, followed by pallor (60%, pruritus (53% and cutaneous pigmentation (43%. Other cutaneous manifestations included Kyrle′s disease (21%; fungal (30%, bacterial (13% and viral (12% infections; uremic frost (3%; purpura (9%; gynecomastia (1%; and dermatitis (2%. The nail changes included half and half nail (21%, koilonychia (18%, onychomycosis (19%, subungual hyperkeratosis (12%, onycholysis (10%, splinter hemorrhages (5%, Mees′ lines (7%, Muehrcke′s lines (5% and Beau′s lines (2%. Hair changes included sparse body hair (30%, sparse scalp hair (11% and brittle and lusterless hair (16%. Oral changes included macroglossia with teeth markings (35%, xerostomia (31%, ulcerative stomatitis (29%, angular cheilitis (12% and uremic breath (8%. Some rare manifestations of CRF like uremic frost, gynecomastia and pseudo-Kaposi′s sarcoma were also observed. Conclusions: CRF is associated with a complex array of cutaneous manifestations caused either by the disease or by treatment. The commonest are xerosis and pruritus and the early recognition of cutaneous signs can relieve suffering and decrease morbidity.

    Skin disease occur worldwide, affecting people of all nationalities and all skin types. These diseases may have a genetic component and may manifest differently in specific population groups; however, there has been little study on this aspect. If population-based differences exist, it is reasonable to assume that understanding these differences may optimize treatment. While there is a relative paucity of information about similarities and differences in skin diseases around the world, the knowledge-base is expanding. One challenge in understanding population-based variations is posed by terminology used in the literature: including ethnic skin, Hispanic skin, Asian skin, and skin of color. As will be discussed in this article, we recommend that the first three descriptors are no longer used in dermatology because they refer to nonspecific groups of people. In contrast, "skin of color" may be used - perhaps with further refinements in the future - as a term that relates to skin biology and provides relevant information to dermatologists.

    Hydatid cyst disease is common in our part of the world. Cardiac hydatid cyst is its rare manifestation. We report this case of 48-year male having isolated cardiac hydatid cyst, incidentally found on computed tomography. This patient presented in medical OPD of Combined Military Hospital, Lahore with one month history of mild retrosternal discomfort. His general physical and systemic examinations as well as ECG were unremarkable. Chest X-ray showed an enlarged cardiac shadow with mildly irregular left heart border. Contrast enhanced CT scan of the chest showed a large well defined multiloculated non-enhancing cystic lesion with multiple daughter cysts involving wall of left ventricle and overlying pericardium. Serology for echinococcus confirmed the diagnosis of hydatid cyst. Patient was offered the surgical treatment but he opted for medical treatment only. Albendezol was prescribed. His follow-up echocardiography after one month showed no significant decrease in size of the cyst. (author)

    Sarcoidosis is a granulomatous disorder of unknown cause characterized by non-caseating granuloma in young adults. Cardiac involvement is rare and range from 2 to 75% depending on diagnostic criteria. Cardiac involvement in sarcoidosis may be asymptomatic or may manifest as rhythm/conduction troubles or congestive heart failure. The diagnosis and treatment of cardiac sarcoidosis may be challenging. However, advances have come in recent years from the use of cardiac MRI and 18 FDG-TEP scanner, as well as from the stratification of the risk of ventricular tachycardia/fibrillation. Due to the rarity of the disease, there is no reliable prospective large study to guide therapeutic strategy for cardiac sarcoidosis. Corticosteroids are probably efficacious, in particular in case of atrio-ventricular block or moderate heart failure. Immunosuppressive drugs have not been largely studied but methotrexate could be helpful. In refractory forms, TNF-α antagonists have been used with success.

    In this pilot study, we obtained estimates of entrance skin doses and the corresponding effective doses to patients undergoing digital cardiac imaging procedures on a GE Advantx LC/LP Plus system. Data were obtained for six patients undergoing diagnostic examinations and six patients who had interventional procedures. For each patient examination, radiographic techniques for fluoroscopic and digital cine imaging were recorded, together with the irradiation geometry. The projection with the highest exposure resulted in an average skin dose of 0.64 ± 0.41 Gy (maximum of 1.6 Gy). The average patient skin doses taking into account overlapping projections was 1.1 ± 0.8 Gy (maximum of 3.0 Gy). The exposure area product (EAP) incident on the patient was converted into the energy imparted to the patient and the corresponding effective dose. The average patient effective dose was 28 ± 14 mSv (maximum 62 mSv), with the resultant average fatal cancer risk estimated to be of the order of 8x10 -3 . Average doses for interventional procedures in cardiac imaging are higher than those associated with diagnostic examinations by approximately 50%. (author)

    2013-01-01

    A 69-year-old man with multiple skin lesions on his face, neck and upper torso, which first appeared in the 3rd decade of his life, was admitted to our hospital. He had cystic changes in his lungs noted on chest computed tomography (CT) scanning, as well as a left kidney mass. This patient exhibited a rare complex of renal, cutaneous and pulmonary manifestations, eponymously named Birt-Hogg-Dube syndrome, with characteristic skin features (fibrofolliculomas, trichodiscomas and acrochordons). This syndrome is due to an autosomal dominant germ-line mutation of the folliculin (FLCN) gene located at chromosome 17p11.2. Diagnosis and differentiation from other disease complexes including the skin, kidneys and lungs are important in prognostication and management of potentially life-threatening complications such as renal cell carcinoma and pneumothoraces.

    Diabetes mellitus is a widespread endocrine disease with severe impact on health systems worldwide. Increased serum glucose causes damage to a wide range of cell types, including endothelial cells, neurons, and renal cells, but also keratinocytes and fibroblasts. Skin disorders can be found in about one third of all people with diabetes and frequently occur before the diagnosis, thus playing an important role in the initial recognition of underlying disease. Noninfectious as well as infectious diseases have been described as dermatologic manifestations of diabetes mellitus. Moreover, diabetic neuropathy and angiopathy may also affect the skin. Pruritus, necrobiosis lipoidica, scleredema adultorum of Buschke, and granuloma annulare are examples of frequent noninfectious skin diseases. Bacterial and fungal skin infections are more frequent in people with diabetes. Diabetic neuropathy and angiopathy are responsible for diabetic foot syndrome and diabetic dermopathy. Furthermore, antidiabetic therapies may provoke dermatologic adverse events. Treatment with insulin may evoke local reactions like lipohypertrophy, lipoatrophy and both instant and delayed type allergy. Erythema multiforme, leukocytoclastic vasculitis, drug eruptions, and photosensitivity have been described as adverse reactions to oral antidiabetics. The identification of lesions may be crucial for the first diagnosis and for proper therapy of diabetes.

    Total body irradiation and repopulation with syngeneic hemopoietic cells can be used to induce tolerance to major histocompatibility complex (MHC) mismatched heart and kidney grafts in rats and mice. However, this protocol does not work for MHC mismatched skin grafts in rats or mice. Furthermore, LEW rats that accept WF cardiac allografts after irradiation and repopulation reject subsequent WF skin grafts. Treatment of skin allograft donors with methotrexate prior to grafting onto irradiated and reconstituted mice resulted in doubling of the mean survival time. Analysis of which antigens provoked skin graft rejection by irradiation and reconstituted animals revealed the importance of I region antigens. Cardiac allograft acceptance by irradiated and reconstituted animals is mediated by suppressor cells found in the spleen. Adoptively tolerant LEW rats accepted WF skin grafts in 50% of grafted animals. Analysis of this phenomenon revealed that the adoptive transfer procedure itself was important in achieving skin allograft acceptance by these animals. In general, it seems that the lack of ability of irradiated and reconstituted animals to accept fully MHC disparate skin grafts results from the inability of these animals to suppress lymph node effector cells against I region antigen seen on highly immunogenic allogeneic Langerhans cells in the skin

    To determine skin changes in patients of End Stage Renal Disease (ESRD) on maintenance hemodialysis (MHD) and factors affecting these changes. Study Design:Cross-sectional observational study. Place and Duration of Study:Nephrology Department, Mayo Hospital, Lahore in collaboration with Dermatology Department, King Edward Medical University, Lahore, from October 2015 to January 2016. Methodology:Two hundred patients who were undergoing MHD for more than three months were included in the study. Patients' demographic data, laboratory reports and dialysis records were noted in a predesigned questionnaire. Skin examination was carried out by consultant dermatologist after patient's permission. Results:Among 200 patients included in study, 105 were males and rest of them were females. Major causes of ESRD were Diabetes Mellitus (n=83, 41.5%, followed by Hypertension (n=80, 40%), Nephrolithiasis (n=15, 7.5%) and Chronic glomerulonephritis (n=5, 2.5%). At least one cutaneous finding was present in every patient. Common skin findings observed were pigmentation (86%), xerosis (83%), pallor (79%), pruritus (69%), acquired ichthyosis (50.5%), and bacterial skin infections (18.5%). Among them, nail manifestations were half-and-half nails (52%), nychomycosis (30.5%), onycholysis (20.5%), subungual hyperkeratosis (23.5%), and Mee's lines (7.5). Among hair changes were sparse scalp hair (38.5%), brittle and lustreless hair (28%). The factors contributing to skin changes were patient's age, cause of ESRD, anti HCV positivity, high urea and creatinine levels, duration and frequency of hemodialysis, hemoglobin levels, calcium phosphate product and socioeconomic status. Some skin manifestations were interrelated with each other like xerosis with pruritus (p<0.001), pruritus with bacterial infection (p<0.022), acquired Ichthyosis (p=0.008) and hair changes (p=0.035). Conclusion:ESRD patients on hemodialysis develop various skin changes during the course of disease

    Full Text Available Background: Chronic kidney disease (CKD-associated mucocutaneous manifestations significantly impair the quality of life but often remain understudied. They may also vary across regions, socioeconomic and nutritional status, and racial differences. Objectives: To study the patterns of mucocutaneous disorders and their prevalence in CKD patients irrespective of clinical stage or dialysis status. Materials and Methods: 122 (M:F = 77:45 patients aged 21‒85 (Mean ± SD = 57.5 ± 14.0 years having CKD for 3 month to 5 years were studied for mucocutaneous manifestations. Fifty (41% patients were on hemodialysis for 1‒42 months. Detailed medical history, clinical and mucocutaneous examination, and lab investigations were performed. KOH mounts, skin biopsy, Gram's and Giemsa staining, bacterial or fungal cultures were performed as required. Results: Xerosis in 93 (76.2%, skin pallor in 61 (50%, pruritus in 57 (46.7%, pigmentation in 47 (38.5%, and purpura in 18 (14.8% patients were the major dermatoses. Bullous lesions and perforating folliculitis occurred in 3 (2.5% patients each. Major nail abnormalities were pallor (in 35.2%, absent lunula (in 23.8%, nail discoloration (in 18%, and “half-and-half nails” in 16.4% patients, respectively. Hair abnormalities included sparse scalp and body hairs (in 35.2% and 13.1%, respectively and lusterless hair in 12.3% patients. Coated tongue (in 14.8%, xerostomia (in 12.3%, and macroglossia with teeth indention (in 7.4% patients were the mucosal manifestations. Conclusions: Xerosis, pruritus, skin pallor/pigmentary changes, nail pallor, absent lunula, nail discoloration, sparse hairs, coated tongue, xerostomia, macroglossia, and infections were the most common mucocutaneous manifestations in the studied patients irrespective of hemodialysis status. Cold and dry climates might be additional aggravators for xerosis/pruritus. Lifelong follow-up may be needed to reduce the morbidity associated with CKD

    2015-09-01

    Full Text Available Background: The dermatological manifestations associated with intestinal diseases are becoming more frequent, especially now when new clinical entities, such as Non-Celiac Gluten Sensitivity (NCGS, are identified. The existence of this new entity is still debated. However, many patients with diagnosed NCGS that present intestinal manifestations have skin lesions that need appropriate characterization. Methods: We involved 17 patients affected by NCGS with non-specific cutaneous manifestations who got much better after a gluten free diet. For a histopathological and immunopathological evaluation, two skin samples from each patient and their clinical data were collected. Results: The median age of the 17 enrolled patients affected by NCGS was 36 years and 76% of them were females. On the extensor surfaces of upper and lower limbs in particular, they all presented very itchy dermatological manifestations morphologically similar to eczema, psoriasis or dermatitis herpetiformis. This similarity was also confirmed histologically, but the immunopathological analysis showed the prevalence of deposits of C3 along the dermo-epidermal junction with a microgranular/granular pattern (82%. Conclusions: The exact characterization of new clinical entities such as Cutaneous Gluten Sensitivity and NCGS is an important objective both for diagnostic and therapeutic purposes, since these are patients who actually benefit from a GFD (Gluten Free Diet and who do not adopt it only for fashion.

    Full Text Available The association of thyroid disorders with skin manifestations is complex. Both hypothryoidism and hyperthyroidism are known to cause these changes. In order to study this association of skin changes in relation to hypothyroidism, a study was carried out in the outpatients department of Dermatology of Dayanand Medical College and Hospital, Ludhiana, over a period of 3 months from Jan-March 2005. Thirty two patients were enrolled in the study and parameters were noted regarding history, general symptoms, cutaneous signs and associated diseases. We found gain in weight (71.85% and lethargy (65.62% to be the most common complaints. On cutaneous examination, dry, coarse texture of the skin (56%, pigmentary disorders (37.5% and telogen effluvium (40.62% were the most common findings. Other associated disorders were vitiligo, melasma, pemphigus, alopecia areata, xanthelasma palpebrarum, etc.

    Many childhood diseases often present with skin abnormalities with which radiologists are largely unfamiliar. Knowledge of associated dermatologic manifestations may aid the radiologist in confirming the diagnosis and recommending targeted imaging of affected organs. We review the imaging findings in childhood diseases associated with dermatologic manifestations. Diseases include dermatologic findings which herald underlying malignancy (Neuroblastoma, leukemia/lymphoma, Langerhans cell histiocytosis),are associated with risk of malignancy (Epidermolysis Bullosa, basal cell nevus syndrome, Cowden's syndrome, Tuberous Sclerosis),or indicate a systemic inflammatory/immune disorder (Kawasaki's disease, Henoch Schonlein Purpura, systemic lupus erythematosus, scleroderma, sarcoidosis, dermatomyositis and immune thrombocytopenic purpura). Familiarity with pertinent findings in childhood diseases presenting with dermatologic manifestations in childhood diseases aids the radiologist in confirming the diagnosis and guiding imaging workup.

    Blunt cardiac injury (BCI) may manifest as cardiac contusion or, more rarely, as pericardial or myocardial rupture. Computed tomography (CT) is performed in the vast majority of blunt trauma patients, but the imaging features of cardiac contusion are not well described. To evaluate CT findings and associated injuries in patients with clinically diagnosed BCI. We identified 42 patients with blunt cardiac injury from our institution's electronic medical record. Clinical parameters, echocardiography results, and laboratory tests were recorded. Two blinded reviewers analyzed chest CTs performed in these patients for myocardial hypoenhancement and associated injuries. CT findings of severe thoracic trauma are commonly present in patients with severe BCI; 82% of patients with ECG, cardiac enzyme, and echocardiographic evidence of BCI had abnormalities of the heart or pericardium on CT; 73% had anterior rib fractures, and 64% had pulmonary contusions. Sternal fractures were only seen in 36% of such patients. However, myocardial hypoenhancement on CT is poorly sensitive for those patients with cardiac contusion: 0% of right ventricular contusions and 22% of left ventricular contusions seen on echocardiography were identified on CT. CT signs of severe thoracic trauma are frequently present in patients with severe BCI and should be regarded as indirect evidence of potential BCI. Direct CT findings of myocardial contusion, i.e. myocardial hypoenhancement, are poorly sensitive and should not be used as a screening tool. However, some left ventricular contusions can be seen on CT, and these patients could undergo echocardiography or cardiac MRI to evaluate for wall motion abnormalities. Copyright © 2015 Elsevier Ltd.

    Full Text Available Purpose : To evaluate myocardial conductivity to understand cardiac involvement in patients with mitochondrial disease. Methods : We performed retrospective study on fifty-seven nonspecific mitochondrial encephalopathy patients with no clinical cardiac manifestations. The patients were diagnosed with mitochondrial respiratory chain complex defects through biochemical enzyme assays of muscle tissue. We performed standard 12-lead electrocardiography (ECG on all patients. Results : ECG abnormalities were observed in 30 patients (52.6%. Prolongation of the QTc interval (&gt;440 ms was seen in 19 patients (33.3%, widening of the corrected QRS interval in 15 (26.3%, and bundle branch block in four (7.0%. Atrioventricular block, premature atrial contraction and premature ventricular contraction were seen in two patients each (3.5% and Wolff-Parkinson-White syndrome in one patient (1.8%. Conclusion : Given this finding, we recommend active screening with ECG in patients with mitochondrial disease even in patients without obvious cardiac manifestation.

    2012-01-01

    Full Text Available BACKGROUND: Cystic echinococcosis (CE can affect the heart and the vena cava but few cases are reported. METHODS: A retrospective case series of 11 patients with cardiac and/or endovascular CE, followed-up over a period of 15 years (1995-2009 is reported. RESULTS: Main clinical manifestations included thoracic pain or dyspnea, although 2 patients were asymptomatic. Cysts were located mostly in the right atrium and inferior vena cava. Nine patients were previously diagnosed with disseminated CE. Echocardiography was the diagnostic method of choice, although serology, electrocardiogram, chest X-ray, computed tomography/magnetic resonance imaging and histology aided with diagnosis and follow-up. Nine patients underwent cardiac surgery and nine received long-term antiparasitic treatment for a median duration of 25 months (range 4-93 months. One patient died intra-operatively due to cyst rupture and endovascular dissemination. Two patients died 10 and 14 years after diagnosis, due to pulmonary embolism (PE and cardiac failure, respectively. One patient was lost to follow-up. Patients who had cardiac involvement exclusively did not have complications after surgery and were considered cured. There was only one recurrence requiring a second operation. Patients with vena cava involvement developed PEs and presented multiple complications. CONCLUSIONS: Cardiovascular CE is associated with a high risk of potentially lethal complications. Clinical manifestations and complications vary according to cyst location. Isolated cardiac CE may be cured after surgery, while endovascular extracardiac involvement is associated with severe chronic complications. CE should be included in the differential diagnosis of cardiovascular disease in patients from endemic areas.

    Tularemia is a serious and potentially life-threatening zoonosis caused by Francisella tularensis, a highly infective, gram-negative coccobacillus. Although there are plenty of case reports and studies of tularemia outbreaks, the literature is lacking in reports on dermatologic manifestations of the disease. This study aimed to identify skin manifestations in clinical forms of tularemia. A total of 151 patients diagnosed with tularemia at Çankırı State Hospital, Çankırı, Turkey, were retrospectively examined. Dermatologic data for these patients were assessed. The most frequent clinical manifestation of tularemia was the glandular form (49.7%), followed by the oropharyngeal, ulceroglandular, and oculoglandular forms (39.1, 6.0, and 5.3%, respectively). Physical manifestations were observed in 64.5% of females and 56.9% of males. Lymphadenopathy and tonsillitis were the most frequent physical findings and were noted in 57.6 and 25.2% of patients, respectively. Erythema multiforme was found in 17 patients (11.3%), most of whom presented with the oropharyngeal and glandular forms, and was followed by ulcer (6.0%), urticaria (3.3%), erythema nodosum (2.6%), and cellulitis (0.7%). However, it should be noted that this study was retrospective and that its patient sample demonstrated four of the six clinical forms of tularemia. Patients with the oropharyngeal form of tularemia had statistically significantly more physical findings than those with other clinical forms of the disease (P < 0.001). There were statistically more skin findings in the ulceroglandular form (P < 0.001). There was no statistical correlation between serum antibody titers and cutaneous findings (P = 0.585). Although the literature reports that skin lesions are observed more frequently in women than in men, we did not find any statistically significant difference between the sexes in any type of skin lesion. © 2014 The International Society of Dermatology.

    The appearance of skin symptoms in male breast is the main reason for consultation in our context. The aim of this study is to describe the various cutaneous manifestations of male breast cancer through a series of cases collected in a dermatology department. A retrospective study was conducted in the dermatology department at the CHU Ibn Rochd January 1988 to December 2009. All cases of male breast cancer initially diagnosed in dermatology were included. The various epidemiological, clinical, histological and therapeutic data were collected from medical records. Twenty cases were collected. The mean age was 61.25 years. Skin invasion by tumor was found in all patients, and it was the reason for consultation. It was a cutaneous involvement at the nipple and areola (17 cases) and at the periareolar skin (three cases). The clinical appearance of skin involvement was vegetative type in 12 cases, infiltrating with nipple retraction in five cases and nodule with skin change in three cases. The average period of consultation was 25 months. The axillary lymph nodes were noted in 11 patients and distant metastases in eight patients. The cutaneous metastases outside breast were noted in six patients. The histological types were: infiltrating ductal carcinoma in 15 cases (75%), papillary carcinoma in two cases (10%) and non-specific carcinoma in three cases (15%). The treatment was surgery in 14 patients and consisted of radical mastectomy with complete axillary nodal dissection according to Patey. Complementary therapies, chemotherapy or radiotherapy, were indicated in 14 patients. Our single-center study with dermatological recruitment illustrates the frequency and variety of skin disease in male breast cancer and demonstrates that they are still the main reason for consultation in our context. Better information for public and practitioners would allow earlier diagnosis and a more favourable prognosis. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

    Behçet disease (BD) is a systemic immune-mediated vasculitis of unknown origin characterised by recurrent orogenital ulceration, ocular inflammation and skin lesions. The aim of our study was to identify ear, nose and throat (ENT) manifestations associated with BD. Retrospective review of the medical records of all patients diagnosed with BD who attended a tertiary public hospital in Cantabria (Spain) over a period of 22 years. Clinical manifestations, in particular those concerning ENT, were retrieved from medical records. A medical literature review of ENT manifestations was conducted. Thirty-three patients (age range: 17-64 years) were included in the study. Most of them presented oral ulcers (97%). Eight patients (24%) presented oropharyngeal ulcers and 5 patients (15%) experienced audiovestibular symptoms (high frequency sensorineural hearing loss, vertigo and bilateral vestibular hypofunction). One patient had symptoms compatible with vestibular neuronitis as the presentation manifestation of Neuro-Behçet. In 4 patients (12%) the presence of odynophagia secondary to the presence of oropharyngeal lesions, initially interpreted as acute or recurrent tonsillitis, was the first manifestation of the disease, alone or associated with cutaneous or ocular lesions. In addition to the characteristic oral ulcers present in most patients with BD, ulcers in the oropharynx, occasionally interpreted as acute pharyngitis, are also common in these patients. Audiovestibular manifestations frequently appear during the course of the disease and may be the first symptom of central nervous system involvement. Copyright © 2013 Elsevier España, S.L.

    2008-04-01

    Full Text Available Introduction: Primary cardiac tumors are extremely rare in infants and children . Most primary cardiac tumors in pediatric age group are benign, and less than 10% of such tumors are malignant. Many of these tumors are asymptomatic and incidentally diagnosed. The clinical manifestations are very different and includes direct cardiac effect, systemic effect , and embolic phenomena. Every infant or child with an unusual cardiac murmur, unexplained congestive heart failure, or arrhythmia should be evaluated for cardiac tumors. Echocardiography has contributed significantly to the evaluation of these patients. Surgery is the only treatment for primary cardiac tumors that require intervention with a relatively good prognosis. Case Report: The patient was a 20 days old neonate presented with severe congestive heart failure. Evaluation of the patient showed primary cardiac tumor in the left atrium and ventricle. We recommended surgical removal of the tumor but her parents denied surgical intervention at all. Conclusion: After about one year follow up, congestive heart failure symptoms were controlled and the tumor size was decreased.

    Neurocardiology is an emerging specialty that addresses the interaction between the brain and the heart, that is, the effects of cardiac injury on the brain and the effects of brain injury on the heart. This review article focuses on cardiac dysfunction in the setting of stroke such as ischemic stroke, brain hemorrhage, and subarachnoid hemorrhage. The majority of post-stroke deaths are attributed to neurological damage, and cardiovascular complications are the second leading cause of post-stroke mortality. Accumulating clinical and experimental evidence suggests a causal relationship between brain damage and heart dysfunction. Thus, it is important to determine whether cardiac dysfunction is triggered by stroke, is an unrelated complication, or is the underlying cause of stroke. Stroke-induced cardiac damage may lead to fatality or potentially lifelong cardiac problems (such as heart failure), or to mild and recoverable damage such as neurogenic stress cardiomyopathy and Takotsubo cardiomyopathy. The role of location and lateralization of brain lesions after stroke in brain-heart interaction; clinical biomarkers and manifestations of cardiac complications; and underlying mechanisms of brain-heart interaction after stroke, such as the hypothalamic-pituitary-adrenal axis; catecholamine surge; sympathetic and parasympathetic regulation; microvesicles; microRNAs; gut microbiome, immunoresponse, and systemic inflammation, are discussed. © 2017 American Heart Association, Inc.

    Ley, S.; Ley-Zaporozhan, J.

    2015-01-01

    Malformations of the heart and great vessels show a high degree of variation. There are numerous variants and defects with only few clinical manifestations and are only detected by chance, such as a persistent left superior vena cava or a partial anomalous pulmonary venous connection. Other cardiovascular malformations are manifested directly after birth and need prompt mostly surgical interventions. At this point in time echocardiography is the diagnostic modality of choice for morphological and functional characterization of malformations. Additional imaging using computed tomography (CT) or magnetic resonance imaging (MRI) is only required in a minority of cases. If so, the small anatomical structures, the physiological tachycardia and tachypnea are a challenge for imaging modalities and strategies. This review article presents the most frequent vascular, cardiac and complex cardiovascular malformations independent of the first line diagnostic imaging modality. (orig.) [de

  15. Malignant arrhythmia as the first manifestation of Wolff-Parkinson-White syndrome: a case with minimal preexcitation on electrocardiography.

    Gungor, B; Alper, A T

    2013-09-01

    Wolff-Parkinson-White (WPW) syndrome is defined as the presence of an accessory atrioventricular pathway which is manifested as delta waves and short PR interval on electrocardiography (ECG). However, some WPW cases do not have typical findings on ECG and may remain undiagnosed unless palpitations occur. Sudden cardiac death may be the first manifestation of WPW and develops mostly secondary to degeneration of atrial fibrillation into ventricular fibrillation. In this report, we present a case of undiagnosed WPW with minimal preexcitation on ECG and who suffered an episode of malignant arrhythmia as the first manifestation of the disease.

    Full Text Available Hydatid disease is a parasitic infection caused by larvae of Echinococcus granulosus. Cardiac involvement in hydatid disease is uncommon, constituting only 0.5 - 2% of all cases of hydatidosis. Most patients with cardiac echinococcosis are asymptomatic, and the disease is often latent because a hydatid cyst in the heart grows very slowly. Only approximately 10 % of patients, especially those with large hydatid cysts, have clinical manifestations. Precordial pain is the one of the common symptoms and is most often vague and does not resemble angina pectoris.

    Fabry disease is a hereditary disorder. Clinical manifestations are multisystemic. The majority of the patients remain undiagnosed until late in life, when alterations could be irreversible. Early detection of cardiac symptoms is of major interest in Fabry's disease (FD) in order to gain access to enzyme replacement therapy. Echo-Doppler tissular imaging (TDI) has been used as a cardiologic early marker in FD. This study is intended to determine whether the cardiac magnetic resonance is as useful tool as TDI for the early detection of cardiac affectation in FD. Echocardiography, tissue Doppler and Cardio magnetic resonance was performed in 20 patients with confirmed Fabry Disease. Left ventricular hypertrophy was defined as septum and left ventricular posterior wall thickness ≥12 mm. An abnormal TDI velocity was defined as (Sa), (Ea) and/or (Aa) velocities gadolinium-enhanced images sequences were obtained using magnetic resonance. Twenty patients included in the study were divided into three groups: 1. Those without left ventricular hypertrophy nor tissue Doppler impairment 2. Those without left ventricular hypertrophy and tissue Doppler impairment 3. Those with left ventricular hypertrophy and Tissue Doppler impairment. Late gadolinium enhancement was found in only one patient, who has already altered DTI and LVH. Tissue Doppler imaging (TDI) is the only diagnostic tool able to provide early detection of cardiac affectation in patients with FD. Magnetic resonance provides information of the disease severity in patients with LVH, but can not be used as an early marker of cardiac disease in patients with FD. However MRI could be of great value for diagnostic stratification. Copyright © 2009 Elsevier España, S.L. All rights reserved.

    Full Text Available Background: Polycystic ovary syndrome (PCOS is one of the most common endocrine disorders in women, affecting 5–10% of reproductive-aged women. The dermatologic manifestations of hyperandrogenism, chiefly hirsutism, acne vulgaris, androgenic alopecia, and acanthosis nigricans, are among the cardinal manifestations of PCOS. Aim: To study the incidence and prevalence of various cutaneous manifestations in patients with PCOS and to correlate these skin manifestations with hormonal changes. Settings and Design: This study was conducted at a dermatology centre over a period of 1 year from November 2012 to 2013. Materials and Methods: The present study included 100 women diagnosed to have PCOS. Hormonal analysis as well as radiological assessment was done in all the cases. Cutaneous manifestations were ascertained and inferences were drawn. Statistical Analysis: Statistical analysis was carried out by the Chi-square test and independent samples t-test. Statistical significance was determined at a level of P < 0.05. Results: In our study, the prevalence of hirsutism, acne, female pattern hair loss, acanthosis nigricans, seborrhea, striae and acrochordons was 78%, 48%, 31%, 30%, 29%, 13%, and 9%, respectively. Conclusion: Dermatologic manifestations of PCOS play a significant role in making the diagnosis and constitute a substantial portion of the symptoms experienced by women with this syndrome.

    Patient skin doses were measured using Kodak EDR2 film for 20 coronary angiography (CA) and 32 percutaneous transluminal coronary angioplasty (PTCA) procedures. For CA, all skin doses were well below 1 Gy. However, 23% of PTCA patients received skin doses of 1 Gy or more. Dose-area product (DAP) was also recorded and was found to be an inadequate indicator of maximum skin dose. Practical compliance with ICRP recommendations requires a robust method for skin dosimetry that is more accurate than DAP and is applicable over a wider dose range than EDR2 film.

    A 51-year-old man presented with progressive tiredness, proximal muscle weakness, hair loss and weight gain for months. The patient showed mild pretibial myxedema and dry skin. Laboratory findings revealed strongly elevated cardiac enzymes as well as marked hypothyroidism. The electrocardiogram, echocardiography, abdominal sonography and chest X-ray were unremarkable. Thyroid ultrasound demonstrated features of Hashimoto thyroiditis. The findings supported the diagnosis of an overt hypothyroidism with myxedema and rhabdomyolysis. After starting levothyroxine and volume substitution laboratory parameters and clinical condition slowly normalized. Severe overt hypothyroidism may rarely present primarily as myopathy with myositis and cardiac involvement. © Georg Thieme Verlag KG Stuttgart · New York.

    2011-01-01

    Full Text Available The Hutchinson-Gilford progeria (HGP syndrome is an extremely rare genetic condition characterized by an appearance of accelerated aging in children. The word progeria is derived from the Greek word progeros meaning ′prematurely old′. It is caused by de novo dominant mutation in the LMNA gene (gene map locus 1q21.2 and characterized by growth retardation and accelerated degenerative changes of the skin, musculoskeletal and cardiovascular systems. The most common ocular manifestations are prominent eyes, loss of eyebrows and eyelashes, and lagophthalmos. In the present case some additional ocular features such as horizontal narrowing of palpebral fissure, superior sulcus deformity, upper lid retraction, upper lid lag in down gaze, poor pupillary dilatation, were noted. In this case report, a 15-year-old Indian boy with some additional ocular manifestations of the HGP syndrome is described.

    Although the human visual system is not sufficiently sensitive to perceive blood circulation, blood flow caused by cardiac activity makes slight changes on human skin surfaces. With advances in imaging technology, it has become possible to capture these changes through digital cameras. However, it is difficult to obtain clear physiological signals from such changes due to its fineness and noise factors, such as motion artifacts and camera sensing disturbances. We propose a method for extracting physiological signals with improved quality from skin colored-videos recorded with a remote RGB camera. The results showed that our skin color magnification method reveals the hidden physiological components remarkably in the time-series signal. A Korea Food and Drug Administration-approved heart rate monitor was used for verifying the resulting signal synchronized with the actual cardiac pulse, and comparisons of signal peaks showed correlation coefficients of almost 1.0. In particular, our method can be an effective preprocessing before applying additional postfiltering techniques to improve accuracy in image-based physiological signal extractions.

    2014-01-01

    Twenty-eight goldring surgeonfish, Ctenochaetus strigosus (Bennett), manifesting skin lesions and originating from the north-western and main Hawaiian Islands were examined. Skin lesions were amorphous and ranged from simple dark or light discolouration to multicoloured tan to white sessile masses with an undulant surface. Skin lesions covered 2–66% of the fish surface, and there was no predilection for lesions affecting a particular part of the fish. Males appeared over-represented. Microscopy revealed the skin lesions to be hyperplasia, melanophoromas or iridophoromas. The presence of skin tumours in a relatively unspoiled area of Hawaii is intriguing. Explaining their distribution, cause and impact on survivorship of fish all merit further study because C. strigosus is an economically important fish in the region.

  8. Cutaneous Manifestations of Human and Murine Leishmaniasis

    Directory of Open Access Journals (Sweden)

    Breanna M. Scorza

    2017-06-01

    Full Text Available The leishmaniases are diseases caused by pathogenic protozoan parasites of the genus Leishmania. Infections are initiated when a sand fly vector inoculates Leishmania parasites into the skin of a mammalian host. Leishmania causes a spectrum of inflammatory cutaneous disease manifestations. The type of cutaneous pathology is determined in part by the infecting Leishmania species, but also by a combination of inflammatory and anti-inflammatory host immune response factors resulting in different clinical outcomes. This review discusses the distinct cutaneous syndromes described in humans, and current knowledge of the inflammatory responses associated with divergent cutaneous pathologic responses to different Leishmania species. The contribution of key hematopoietic cells in experimental cutaneous leishmaniasis in mouse models are also reviewed and compared with those observed during human infection. We hypothesize that local skin events influence the ensuing adaptive immune response to Leishmania spp. infections, and that the balance between inflammatory and regulatory factors induced by infection are critical for determining cutaneous pathology and outcome of infection.

    Peeling skin syndrome is a rare genodermatosis characterized by variably pruritic superficial generalized peeling of the skin with several genes involved until now little is known about the association between FLG2 and peeling skin syndrome. We describe multiple family members from a consanguineous Saudi family with peeling skin syndrome. Next Generation Sequencing identifies a cosegregating novel variant in FLG2 c.632C>G (p.Ser211*) as a likely etiology in this family. Here, we reported on the clinical manifestation of homozygous loss of function variant in FLG2 as a disease-causing gene for peeling skin syndrome and expand the dermatology findings. © 2017 Wiley Periodicals, Inc.

    2016-07-01

    Childhood obesity has been linked to cardiovascular disease (CVD) risk in adulthood. Of great concern is the expected increase in the population's CVD burden in relation to childhood obesity. This is compounded by the risk related to chronic hyperglycemia exposure in youth with type 2 diabetes. We herein provide an overview of the spectrum of early cardiovascular disease manifestation in youth with obesity and type 2 diabetes, in particular abnormalities in cardiac structure and function. Cardiac remodeling and adverse target organ damage is already evident in the pediatric age group in children with obesity and type 2 diabetes. This supports the importance of intensifying obesity prevention efforts and early intervention to treat comorbidities of obesity in the pediatric age group to prevent cardiac events in early adulthood.

    2016-05-01

    Although the diversity of the clinical manifestations of syphilis is well-known, atypical presentations can also occur. Such atypical presentations are associated with a high risk of transmission as a result of diagnostic confusion and treatment delays owing to the disease's ability to mimic other common skin diseases, deviate from classic clinical presentations, and adopt unique forms. Cases of atypical syphilis have been described most frequently in patients with concomitant human immunodeficiency virus (HIV) infection. Because the incidence of syphilis has been growing over recent years -particularly in patients with HIV co-infection- dermatologists need to be familiar with the less well-known clinical presentations of this venereal disease.

    2016-01-01

    Full Text Available Wolf–Hirschhorn syndrome (WHS is a condition of developmental delay and dysmorphology caused by a deletion of short arm of chromosome 4. The main characteristics of WHS are intra and extrauterine growth retardation, mental retardation with typical facial dysmorphism, microcephaly, and midline fusion defects. The diagnosis is based on clinical features and chromosomal analysis, e.g., microsatellite analysis or molecular cytogenetic techniques and fluorescence in situ hybridization (FISH to detect the deletion. Prenatal diagnosis is possible by FISH. Though no specific treatment is available, supportive management can be fruitful. Here, we describe a female baby with a 4p deletion, who had the majority of the main phenotypic features of WHS and severe congenital heart disease manifesting at birth. The case emphasized that any fetus with intrauterine growth retardation, dysmorphic features on antenatal scan, and midline defects should raise a suspicion of WHS. Conventional cytogenetic studies can miss the diagnosis; hence, these cases should be further investigated using molecular cytogenetic techniques such as FISH or array-comparative genomic hybridization.

    The variable symptoms and signs of pulmonary vasculitis are a diagnostic and therapeutic challenge. Vasculitis should be considered in rapidly progressing, severe and unusual manifestations of pulmonary disease. Clinical examination of other organ systems typically affected by vasculitis such as skin and kidney and autoantibody measurements are complementary approaches to manage this situation. Pulmonary involvement is common in small vessel vasculitis including anti-GBM disease (Goodpasture syndrome) and the ANCA-associated vasculitides. Life threatening pulmonary hemorrhage and irreversible damage of other organs, frequently the kidney, are important complications necessitating rapid diagnosis of these conditions.Vasculitides are rare diseases of multiple organs and therapies including biologics are evolving rapidly, requiring cooperation of specialities and with specialized centres to achieve best patient care. All involved physicians should be aware of typical complications of immunosuppressive therapy. © Georg Thieme Verlag KG Stuttgart · New York.

    DEFF Research Database (Denmark)

    Ferrero-Miliani, Laura; Holst, Anders Gaarsdal; Pehrson, Steen

    2010-01-01

    Sudden cardiac death (SCD) may be the first and final manifestation of several heart diseases. In the young, SCD is often caused by a hereditary cardiac disease. As the most frequently seen inherited cardiac diseases have an autosomal-dominant pattern of inheritance, half of the first......-degree relatives are at risk of having or developing the same disease. Therefore, screening of these high-risk relatives is a rational approach to reduce the incidence of SCD. To offer family screening and counseling, the cause of death should be carefully established. Autopsy is only performed in a limited number...... a limited number of inherited cardiac diseases associated with SCD are without any structural changes. In other cases, the autopsy may reveal noncardiac causes of death, which is also important for reassuring the relatives. However, in cases with no autopsy or negative findings, thorough clinical...

    Objectives There are no guidelines on the use of echocardiography to detect cardiac manifestations of childhood-onset systemic lupus erythematosus (SLE). We quantify the prevalence of acute cardiac disease in youth with SLE, describe echocardiogram utilization at SLE diagnosis, and compare regional echocardiogram use with incident cardiac diagnoses. Methods Using the Clinformatics® DataMart (OptumInsight, Eden Prairie, MN) de-identified United States administrative database from 2000 to 2013, we identified youth ages 5-24 years with new-onset SLE (≥3 ICD-9 SLE codes 710.0, > 30 days apart) and determined the prevalence of diagnostic codes for pericardial disease, myocarditis, endocarditis, and valvular insufficiency. Multiple logistic regression was used to identify factors associated with echocardiography during the baseline period, up to one year before or six months after SLE diagnosis. We calculated a regional echocardiogram utilization index, which is the ratio of observed use over the mean predicted probability based on all available baseline characteristics. Spearman's rank correlation coefficient was used to evaluate the association between regional echocardiogram utilization indices and percentage of imaged youth diagnosed with their first cardiac manifestation following echocardiography. Results Among 699 youth with new-onset SLE, 18% had ≥ 1 diagnosis code for acute cardiac disease, of which valvular insufficiency and pericarditis were most common. Twenty-five percent of all youth underwent echocardiogram during the baseline period. Regional echocardiogram use was positively correlated with the percentage of imaged youth found to have cardiac disease (ρ = 0.71, p = 0.05). There was up to a five-fold difference in adjusted odds of baseline echocardiography between low- and high-utilizing regions (OR = 0.19, p = 0.007). Conclusion Nearly one-fifth of youth with new-onset SLE have acute cardiac manifestations; however, use of

    Full Text Available Background. Systemic lupus erithematodes (SLE is chronic, often febrile, multisystemic disease unknown origin and relapsing course which affects connective tissue of the skin, joints, kidney and serous membranes. Gastrointestinal manifestations are rarely the first sign of systemic lupus erythematosus. Case report. We presented a female patient, 35 years old, whose first symptoms of SLE were paralitic ileus (chronic intestinal pseudo-obstruction and polyserositis (pleural effusion and ascites. Except for high parameters of inflammation, leucopenia and thrombocytopenia, all immunological and laboratory tests for SLE were negative in the onset of the disease. During next six months the patient had clinical signs of paralitic ileus several times and was twice operated with progressive malabsorptive syndrome. The full picture of SLE was manifested seven months later associated with lupus nephritis. Treatment with cyclophosphamide, corticosteroids and total parenteral nutrition (30 days induced stable remission of the disease. Conclusion. The SLE can be initially manifested with gastroenterological symptoms without any other clinical and immunologic parameters of the disease. If in patients with SLE and gastrointestinal tract involvement malabsorption syndrom is developed, a treatment success depends on both immunosupressive therapy and total parenteral nutrition.

    Churg-Strauss syndrome, recently renamed eosinophilic granulomatosis with polyangiitis (EGPA), is a rare form of systemic vasculitis, characterized by disseminated necrotizing vasculitis with extravascular granulomas occurring among patients with asthma and tissue eosinophilia. EGPA is classified as a small and medium-sized vessel vasculitis associated with antineutrophil cytoplasmic antibodies (ANCA) and the hypereosinophilic syndrome. Typical clinical features include asthma, sinusitis, transient pulmonary infiltrates and neuropathy. Blood eosinophils are often >1500/µl or more than 10% on the differential leukocyte count. Blood eosinophils should always be tested in unexplained cardiac disorders, and may normalize even after low doses of corticosteroids. ANCA are positive in 40-60% of cases, mainly anti-myeloperoxidase. Heart involvement occurs in approximately 15-60% of EGPA patients, especially those who are ANCA negative. Any cardiac structure can be involved, and patients present with myocarditis, heart failure, pericarditis, arrhythmia, coronary arteritis, valvulopathy, intracavitary cardiac thrombosis. Although cardiovascular involvement is usually an early manifestation, it can also occur later in the course of the disease. A significant proportion of patients with cardiac involvement is asymptomatic. In the absence of symptoms and major ECG abnormalities, cardiac involvement may be detected in nearly 40% of the patients. All patients with EGPA should be studied not only with a detailed history of cardiac symptoms and ECG, but also with echocardiography; if abnormalities are detected, a cardiac magnetic resonance study should be performed. Coronary angiography and endomyocardial biopsy should be reserved to selected cases. Heart involvement carries a poor prognosis and causes 50% of the deaths of these patients. It is often insidious and underestimated. Optimal therapy is therefore important and based on high-dose corticosteroids plus immunosuppressive

    Scleroderma refers to an autoimmune connective tissue fibrosing disease, including three different subsets: localized scleroderma, limited cutaneous systemic sclerosis, and diffuse cutaneous systemic sclerosis with divergent patterns of organ involvement, autoantibody profiles, management, and prognostic implications. Although systemic sclerosis is considered the disease prototype that causes cutaneous sclerosis, there are many other conditions that can mimic and be confused with SSc. They can be classified into immune-mediated/inflammatory, immune-mediated/inflammatory with abnormal deposit (mucinoses), genetic, drug-induced and toxic, metabolic, panniculitis/vascular, and (para)neoplastic disorders according to clinico-pathological and pathogenetic correlations. This article reviews the clinical presentation with emphasis on cutaneous disease, etiopathogenesis, diagnosis, and treatment options available for the different forms of scleroderma firstly and for scleroderma-like disorders, including scleromyxedema, scleredema, nephrogenic systemic fibrosis, eosinophilic fasciitis, chronic graft-versus-host disease, porphyria cutanea tarda, diabetic stiff-hand syndrome (diabetic cheiroartropathy), and other minor forms. This latter group of conditions, termed also scleroderma mimics, sclerodermiform diseases, or pseudosclerodermas, shares the common thread of skin thickening but presents with distinct cutaneous manifestations, skin histology, and systemic implications or disease associations, differentiating each entity from the others and from scleroderma. The lack of Raynaud's phenomenon, capillaroscopic abnormalities, or scleroderma-specific autoantibodies is also important diagnostic clues. As cutaneous involvement is the earliest, most frequent and characteristic manifestation of scleroderma and sclerodermoid disorders, dermatologists are often the first-line doctors who must be able to promptly recognize skin symptoms to provide the affected patient a correct

    Diabetes mellitus (DM) is the most common of the endocrine disorders. Mucocutaneous manifestations of diabetes mellitus are many and vary from trivial to life-threatening. Sometimes, mucocutaneous disorders may herald the onset of diabetes. To study the pattern of mucocutaneous manifestations in diabetics and role of it in diagnosing diabetes mellitus and its complications. It was a longitudinal observational study of patients having diabetes with skin complaints attending skin outdoor department or admitted in wards for any reason in a tertiary care hospital. Total 300 patients were included in the study. Detailed history, clinical examination, and relevant investigations were done to diagnose the mucocutaneous disorders, diabetes, and diabetic complications. The data was analyzed by using Epi info software. Demographic profile shown majority of cases (78.66%) in more than 40 years of age with almost equal male and female preponderance. Mucocutaneous manifestations as presenting feature of diabetes were observed in 21.67% cases. Infections were most common in 119 (39.66%) cases, followed by acanthosis nigricans in 46 (15.33%) cases. Various associated complications like hypertension, retinopathy, hyperlipidemia, coronary artery disease, neuropathy, nephropathy, and diabetic ketoacidosis were observed in 160 (53.3%). Skin is the mirror, which reflects internal diseases; this aptly applies to skin and diabetes mellitus. Through awareness about cutaneous manifestations of DM, dermatologist can not only take credit for detecting DM but also facilitate early diagnosis of systemic complications of DM. This is immensely beneficial to patients in long run.

    Programming with an insult or stimulus during critical developmental life stages shapes metabolic disease through divergent mechanisms. Cardiovascular disease increasingly contributes to global morbidity and mortality, and the heart as an insulin-sensitive organ may become insulin resistant, which manifests as micro- and/or macrovascular complications due to diabetic complications. Cardiogenesis is a sequential process during which the heart develops into a mature organ and is regulated by several cardiac-specific transcription factors. Disrupted cardiac insulin signalling contributes to cardiac insulin resistance. Intrauterine under- or overnutrition alters offspring cardiac structure and function, notably cardiac hypertrophy, systolic and diastolic dysfunction, and hypertension that precede the onset of cardiovascular disease. Optimal intrauterine nutrition and oxygen saturation are required for normal cardiac development in offspring and the maintenance of their cardiovascular physiology. PMID:29484207

    Cardiac implantable electronic device (CIED) infection is a major complication that is associated with increased morbidity and mortality. Recent data suggested a relationship between the antiseptic agent used for skin preparation at time of CIED procedure and risk for infection. On April 30, 2011, we changed the antiseptic agent used for skin preparation at our tertiary care facility from chlorhexidine-alcohol to povidone-iodine for all CIED procedures. We retrospectively reviewed records of all patients who underwent CIED procedure 1 year before and after the change. CIED infection was defined as pocket or endovascular systemic infection that required removal within 1 year of the index procedure. We examined if the change affected the risk of CIED infection. A total of 2,792 patients underwent 2,840 CIED procedures; 1,748 (61.5%) had implantable cardioverter defibrillator procedures and 1,092 (38.4%) had permanent pacemaker procedures. Chlorhexidine-alcohol agent was used in 1,450 (51.1%) procedures, and povidone-iodine agent was used in 1,390 (48.9%). After 1 year of follow-up, 31 patients (1.09%) developed CIED infection that required system removal. The 1-year infection rate was 1.1% among both antiseptic agent groups and there were no significant differences in the infection presentations among both groups (P = 0.950). Multivariate Cox proportional hazards regression model showed that risk factors for infection within 1 year included age, diabetes, and African American race. In one large cohort of patients undergoing CIED procedures, the antiseptic agent used for skin preparation (chlorhexidine-alcohol vs povidone-iodine) was not associated with increased risk of developing CIED infection. ©2014 Wiley Periodicals, Inc.

    Psoriasis is a common, chronic, inflammatory skin condition in which up to 42% of patients may develop psoriatic arthritis. Consequently, dermatologists and rheumatologists frequently manage the same patient for psoriasis and psoriatic arthritis, respectively. Hence, it is important for the two specialties to understand one another and work together to optimise care of patients with psoriatic disease. This article discusses several areas of clinical concern in which coordination of care is especially critical. First, when selecting a therapeutic modality, it is best to use treatments that improve both the joints and the skin, and exercise caution while using options that can rarely worsen the skin, such as systemic steroids. Second, a close working relationship between the two specialties is critical in making prompt and early diagnosis of psoriatic arthritis. Dermatologists often are on the frontlines for detecting early signs of joint involvement, and the prevalence of undiagnosed PsA among patients with psoriasis is estimated to be 15.5%. Third, in the rare instance of anti-TNF induced paradoxical worsening of the skin disease, it is highly recommended that these patients be referred to dermatologists as soon as possible for optimal management of the skin manifestations. Lastly, dermatologists in the US have a long history of undertreating generalised psoriasis, especially with regards to the use of systemic agents. Therefore, the consideration of systemic agents by the rheumatologist may greatly benefit the patient by treating both the joint and skin manifestations. In summary, this article highlights the importance of interdisciplinary coordination between rheumatologists and dermatologists for which both specialties offer unique and complementary expertise to the care of patients with psoriatic disease.

    Cardiac computed tomography (CT) has evolved into an effective imaging technique for the evaluation of coronary artery disease in selected patients. Two distinct advantages over other noninvasive cardiac imaging methods include its ability to directly evaluate the coronary arteries and to provide a unique opportunity to evaluate for alternative diagnoses by assessing the extracardiac structures, such as the lungs and mediastinum, particularly in patients presenting with the chief symptom of acute chest pain. Some centers reconstruct a small field of view (FOV) cropped around the heart but a full FOV (from skin to skin in the area irradiated) is obtainable in the raw data of every scan so that clinically relevant noncardiac findings are identifiable. Debate in the scientific community has centered on the necessity for this large FOV. A review of noncardiac structures provides the opportunity to make alternative diagnoses that may account for the patient\\'s presentation or to detect important but clinically silent problems such as lung cancer. Critics argue that the yield of biopsy-proven cancers is low and that the follow-up of incidental noncardiac findings is expensive, resulting in increased radiation exposure and possibly unnecessary further testing. In this 2-part review we outline the issues surrounding the concept of the noncardiac read, looking for noncardiac findings on cardiac CT. Part I focused on the pros and cons for and against the practice of identifying noncardiac findings on cardiac CT. Part II illustrates the imaging spectrum of cardiac CT appearances of benign and malignant noncardiac pathology.

    Epidermolysis bullosa (EB) is a group of hereditary chronic disorders, characterized by fragility of the skin and mucous membranes in response to minor mechanical trauma. The objective of this study was to report the case of a young girl diagnosed with epidermolysis bullosa simplex (EBS), transmitted by an autosomal dominant gene. Cutaneous findings included blisters and dystrophy following minimal friction. Recurrent blisters and vesicle formation on the hard palate were the main oral findings. In conclusion, publications concerning the oral and clinical manifestations of EBS are important for providing knowledge and an early multidisciplinary approach that prevents blister formation and improves these patients' quality of life, with the dentist playing an important role in oral health management.

    Full Text Available Primary malignant melanomas of uterine cervix are quite rarely seen neoplasms, and long-life prognosis of patients with this disease is poor. Immunohistochemical methods and exclusion of other primary melanoma sites are used to confirm the diagnosis. As with other melanomas, cervix malignant melanomas may also cause cardiac metastases. Cardiac metastases are among rarely seen but more commonly encountered cases, compared to primary cardiac tumors. Here, we present a case of biatrial cardiac metastases in a 73-year-old patient with uterine cervix malignant melanomas. The patient underwent echocardiography, cardiac magnetic resonance imaging, and computed tomography. Our report shows the importance of advanced diagnostic techniques, such as cardiac magnetic resonance, not only for the detection of cardiac masses, but for a better anatomic definition and tissue characterization. Although the cases of malignant melanomas leading to multiple cardiac metastasis were reported in literature, the metastatic concurrence of malignant melanomas in both right and left atriums is quite rarely encountered as metastatic malignant melanomas. Also, another intriguing point in our case is that the primary lesion of our case was stemmed from uterine cervix, but not skin.

    Objective: To study the radiological features of severe respiratory complications during cardiac catheterizations on pediatric congenital heart disease so as to make early diagnosis and treatment. We also intend to find the mechanism of these complications. Methods: A total of 9 pediatric cases with severe respiratory complications during cardiac catheterizations were included in the study. The clinical manifestations, radiological features, and corresponding treatments were reviewed. Results: Most of the cases had severe hypoxia, with 6 cases presenting with bradycardia. Opacification of two lung fields was found in 7 cases, pulmonary edema in 1 case, and atelectasis of the upper right lung in 1 case. With intubation, oxygen inhalation and administration of certain drugs, all cases were saved except 1 case with pulmonary edema. Conclusion: Severe respiratory complications during cardiac catheterizations on pediatric congenital heart disease are emergent and critical, and they often presented with various manifestations. Early diagnosis and correct treatment are the key to successful salvage. (authors)

    The successive occurrence of pericardial tamponade and myocarditis during a Churg-Strauss syndrome is exceptionally described. We report a patient in whom pericardial tamponade and myocarditis were the presenting manifestation of a Churg-Strauss syndrome. A 58-year-old woman was admitted because of alteration of the clinical status with eosinophilia. One month ago, she was hospitalized for a pericardial tamponade treated by pericardial drainage. Acute myocarditis was diagnosed on chest pain during the second hospitalization. The etiologic inquiry ended in the diagnosis of Churg-Strauss complicated with a double cardiac involvement. A good response of clinical and biological anomalies was obtained after corticosteroid and immunosuppressive treatment. Isolated or multiple involvements of cardiac tunics should lead to make diagnosis of systemic vasculitis. A complete initial assessment and a close observation of the patients followed for Churg-Strauss syndrome is imperative to detect a cardiac achievement and set up an early treatment.

    2016-03-01

    Full Text Available Symptomatic long QT syndrome in pediatric patients is a life-threatening condition. Sometimes, this pathology can be misdiagnosed and erroneously managed as generalized epilepsy due to similar clinical manifestations. The presented case discusses a 13-year-old female patient with generalized epilepsy since the age of 4, admitted for two episodes of resuscitated cardiac arrest due to torsades de pointes and ventricular fibrillation. The final diagnosis of congenital long QT was established and due to the patient's high-risk profile for future cardiac events, implantable cardiac defibrillator was subsequently indicated. Early recognition of congenital long QT and timing of cardiac therapy were crucial and potentially lower the incidence of fatal dysrhythmias commonly associated this condition. In high-risk patients, both medical and interventional therapy can be life-saving.

    Herpes zoster ophthalmicus, in which orbital symptoms and signs appear before the onset of a skin rash, is very rare. We experienced such a case and therefore report on it via magnetic resonance imaging. A 48-year-old man with pain and swelling of left eye and headache presented 2 days before onset of a zoster skin rash. On orbit-al MRI, edematous thickening of the left lateral rectus muscle with high signal intensity was revealed. After contrast injection, the lateral rectus muscle demonstrated heterogenous enhancement. Also, diffuse contrast enhancement was noted at left preseptal space, lacrimal gland and periorbital soft tissue. The man was treated with antiviral agents and prednisolone. Two weeks later, he recovered from the skin manifestations and most of the orbital manifestations except for the diplopia and restricted lateral movement.

    In order to obtain information with regard to behavior of the Ca 2+ receptor, troponin C (TnC), in intact myofilament lattice of cardiac muscle, we investigated Ca 2+ -binding properties of canine ventricular muscle fibers skinned with Triton X-100. Analysis of equilibrium Ca 2+ -binding data of the skinned fibers in ATP-free solutions suggested that there were two distinct classes of binding sites which were saturated over the physiological range of negative logarithm of free calcium concentration (pCa): class I (KCa = 7.4 X 10(7) M-1, KMg = 0.9 X 10(3) M-1) and class II (KCa = 1.2 X 10(6) M-1, KMg = 1.1 X 10(2) M-1). The class I and II were considered equivalent, respectively, to the Ca 2+ -Mg 2+ and Ca 2+ -specific sites of TnC. The assignments were supported by TnC content of the skinned fibers determined by electrophoresis and 45 Ca autoradiograph of electroblotted fiber proteins. Dissociation of rigor complexes by ATP caused a downward shift of the binding curve between pCa 7 and 5, an effect which could be largely accounted for by lowering of KCa of the class II sites. When Ca 2+ binding and isometric force were measured simultaneously, it was found that the threshold pCa for activation corresponds to the range of pCa where class II sites started to bind Ca 2+ significantly. We concluded that the low affinity site of cardiac TnC plays a key role in Ca 2+ regulation of contraction under physiological conditions, just as it does in the regulation of actomyosin ATPase. Study of kinetics of 45 Ca washout from skinned fibers and myofibrils revealed that cardiac TnC in myofibrils contains Ca 2+ -binding sites whose off-rate constant for Ca 2+ is significantly lower than the Ca 2+ off-rate constant hitherto documented for the divalent ion-binding sites of either cardiac/slow muscle TnC or fast skeletal TnC

    Bertherat, Jérôme

    2006-06-06

    The Carney complex (CNC) is a dominantly inherited syndrome characterized by spotty skin pigmentation, endocrine overactivity and myxomas. Skin pigmentation anomalies include lentigines and blue naevi. The most common endocrine gland manifestations are acromegaly, thyroid and testicular tumors, and adrenocorticotropic hormone (ACTH)-independent Cushing's syndrome due to primary pigmented nodular adrenocortical disease (PPNAD). PPNAD, a rare cause of Cushing's syndrome, is due to primary bilateral adrenal defect that can be also observed in some patients without other CNC manifestations or familial history of the disease. Myxomas can be observed in the heart, skin and breast. Cardiac myxomas can develop in any cardiac chamber and may be multiple. One of the putative CNC genes located on 17q22-24, (PRKAR1A), has been identified to encode the regulatory subunit (R1A) of protein kinase A. Heterozygous inactivating mutations of PRKAR1A were reported initially in 45 to 65% of CNC index cases, and may be present in about 80% of the CNC families presenting mainly with Cushing's syndrome. PRKAR1A is a key component of the cAMP signaling pathway that has been implicated in endocrine tumorigenesis and could, at least partly, function as a tumor suppressor gene. Genetic analysis should be proposed to all CNC index cases. Patients with CNC or with a genetic predisposition to CNC should have regular screening for manifestations of the disease. Clinical work-up for all the manifestations of CNC should be performed at least once a year in all patients and should start in infancy. Cardiac myxomas require surgical removal. Treatment of the other manifestations of CNC should be discussed and may include follow-up, surgery, or medical treatment depending on the location of the tumor, its size, the existence of clinical signs of tumor mass or hormonal excess, and the suspicion of malignancy. Bilateral adrenalectomy is the most common treatment for Cushing's syndrome due to PPNAD.

    2012-01-01

    Full Text Available Background: Fahr′s disease is a rare neurodegenerative disorder of unknown cause characterized by idiopathic basal ganglia calcification that is associated with neuropsychiatric and cognitive impairment. No case of Fahr′s disease with associated cardiac conduction disease has been described in the literature to date. The objective of this case report was to describe a young female with various cardiac conduction system abnormalities and bilateral basal ganglia calcifica-tion suggestive of Fahr′s disease. Case Report: A 19-year-old female was transferred to our hospital for a pacemaker insertion. Her past medical history included cognitive impairment and asymptomatic congenital complete heart block since birth. Her manifestations in-cluded cognitive impairment, tremors, rigidity, ataxia, bilateral basal ganglia calcification without clinical manifesta-tions of mitochondrial cytopathy. She also had right bundle branch block, left anterior fascicular block, intermittent complete heart block, atrial arrhythmias with advanced atrioventricular blocks and ventricular asystole manifested by Stokes-Adams seizures, which was diagnosed as epilepsy. Conclusions: According to our knowledge, this was the first case report of a su spected association between Fahr′s disease and isolated cardiac conduction system disease. In addition, this case illustrated that in patients with heart blocks and seizures, a diagnosis of epilepsy needs to be made with caution and such patients need further evaluations by a cardiologist or electrophysiologist to consider pacing and prevent future catastrophic events.

    Effect of multiple ionization and radiation (bremmstrahlung and photorecombination) on skin effect in a dense plasma is investigated. Limiting cases are considered: 1) fast skin-effect, when plasma movement and any types of losses (radiation, electron thermal conductivity) have no time to manifest themselves during short heating times; 2) deceleration of skinning under effect of radiation achieving equilibrium with Joule heating. Self-simulating solutions of the problem for half-space are investigated. The results are applied to analysing experiments with exploding wires. It is shown that under conditions, typical of heavy-current decelerators tubular structures are produced as a result of heat and current skinning under free dispersion of plasma produced during the explosion. Their dimensions are of the order of dozens of microns, and the temperature exceeds 50 eV. The linear power and complete ''tube'' radiation yield at this stage are able to make a substantial contribution to the energy balance in the group

    This study investigated the dose absorbed by tissues surrounding artificial cardiac pacemakers during external beam radiotherapy procedures. The usefulness of out-of-field reference data, treatment planning systems, and skin dose measurements to estimate the dose in the vicinity of a pacemaker was also examined. Measurements were performed by installing a pacemaker onto an anthropomorphic phantom, and using radiochromic film and optically stimulated luminescence dosimeters to measure the dose in the vicinity of the device during the delivery of square fields and clinical treatment plans. It was found that the dose delivered in the vicinity of the cardiac device was unevenly distributed both laterally and anteroposteriorly. As the device was moved distally from the square field, the dose dropped exponentially, in line with out-of-field reference data in the literature. Treatment planning systems were found to substantially underestimate the dose for volumetric modulated arc therapy, helical tomotherapy, and 3D conformal treatments. The skin dose was observed to be either greater or lesser than the dose received at the depth of the device, depending on the treatment site, and so care should be if skin dose measurements are to be used to estimate the dose to a pacemaker. Square field reference data may be used as an upper estimate of absorbed dose per monitor unit in the vicinity of a cardiac device for complex treatments involving multiple gantry angles.

    Full Text Available Foreign body aspiration (FBA is uncommon in the adult population but can be a life-threatening condition. Clinical manifestations vary according to the degree of airway obstruction, and, in some cases, making the correct diagnosis requires a high level of clinical suspicion combined with a detailed history and exam. Sudden cardiac arrest after FBA may occur secondary to asphyxiation. We present a 48-year-old male with no history of cardiac disease brought to the emergency department after an out-of-hospital cardiac arrest (OHCA. The patient was resuscitated after 15 minutes of cardiac arrest. He was initially managed with therapeutic hypothermia (TH. Subsequent history suggested FBA as a possible etiology of the cardiac arrest, and fiberoptic bronchoscopy demonstrated a piece of meat and bone lodged in the left main stem bronchus. The foreign body was removed with the bronchoscope and the patient clinically improved with full neurological recovery. Therapeutic hypothermia following cardiac arrest due to asphyxia has been reported to have high mortality and poor neurological outcomes. This case highlights the importance of early identification of FBA causing cardiac arrest, and we report a positive neurological outcome for postresuscitation therapeutic hypothermia following cardiac arrest due to asphyxia.

    Full Text Available Context: Diabetes mellitus (DM is the most common of the endocrine disorders. Mucocutaneous manifestations of diabetes mellitus are many and vary from trivial to life-threatening. Sometimes, mucocutaneous disorders may herald the onset of diabetes. Aims: To study the pattern of mucocutaneous manifestations in diabetics and role of it in diagnosing diabetes mellitus and its complications. Settings and Design: It was a longitudinal observational study of patients having diabetes with skin complaints attending skin outdoor department or admitted in wards for any reason in a tertiary care hospital. Materials and Methods: Total 300 patients were included in the study. Detailed history, clinical examination, and relevant investigations were done to diagnose the mucocutaneous disorders, diabetes, and diabetic complications. Statistical Analysis Used: The data was analyzed by using Epi info software. Results: Demographic profile shown majority of cases (78.66% in more than 40 years of age with almost equal male and female preponderance. Mucocutaneous manifestations as presenting feature of diabetes were observed in 21.67% cases. Infections were most common in 119 (39.66% cases, followed by acanthosis nigricans in 46 (15.33% cases. Various associated complications like hypertension, retinopathy, hyperlipidemia, coronary artery disease, neuropathy, nephropathy, and diabetic ketoacidosis were observed in 160 (53.3%. Conclusions: Skin is the mirror, which reflects internal diseases; this aptly applies to skin and diabetes mellitus. Through awareness about cutaneous manifestations of DM, dermatologist can not only take credit for detecting DM but also facilitate early diagnosis of systemic complications of DM. This is immensely beneficial to patients in long run.

    Resumption of spontaneous circulation (ROSC) after cardiac arrest is an unnatural pathophysiological state. In 2008, ILCOR has proposed "post-cardiac arrest syndrome (PCAS)". Clinicians must focus on treating to reverse the pathophysiological manifestations of PCAS in bed. Immobility, deconditioning, and weakness are common problems in patients with critical illness. Therapeutic strategies have to be identified to give patients after ROSC the best chance for survival with good neurological function. Concerning the beneficial effects of early mobilization after stroke, and the efficacy of a strategy for whole-body rehabilitation in the earliest days of critical illness on functional outcomes, the intervention of early rehabilitation care by an interdisciplinary team seems to contribute to good long-time outcome of post-cardiac arrest patients.

    2011-01-01

    Full Text Available We report four adult cases of atopic dermatitis (AD complicated by Sjogren's syndrome (SS. The patients fulfilled diagnostic criteria for AD and SS. All cases showed persistent itchy dry skin and eczematous lesions complicated by sicca symptoms including dry eyes and dry mouth with moderate joint pain. One case manifested annular erythema and another manifested widespread discoid erythema. To investigate the underlying cause of dry skin in these cases, sweating function was evaluated using a quantitative sudomotor axon reflex test (QSART in which the axon reflex is stimulated by acetylcholine iontophoresis. The sweating latency time was significantly prolonged in eczematous skin of AD and AD/SS compared to normal controls. Axon reflex (AXR sweat volume was also significantly reduced in AD (normal and eczematous skin and AD/SS (normal and eczema compared to normal control. In contrast, the direct sweat volume of lesional or non-lesional AD skin induced by direct stimulation with acetylcholine was only slightly reduced compared to that in normal controls, but not in SS and lesional skin of AD/SS patients. These results suggest that the impaired sweat response in AD is attributable to an abnormal sudomotor axon reflex, which is accelerated and modulated when complicated by SS resulting in dry skin in the present cases.

    Cat scratch disease is a zoonosis caused by Bartonella henselae, which is transmitted by scratches, bites or exposition to cats saliva (1). The disease typically manifests with local lymphadenitis after bacterial inoculation in the skin, however, there is an atypical systemic presentation in 5 to 10% of patients, which causes unspecific symptoms. There are several imaging findings that lead the radiologist to consider this diagnosis, in order to prevent an invasive procedure, especially if we consider that the majority of cases occur in the pediatric population (2,3). Although in the majority of cases the symptoms and imaging findings resolve spontaneously, there are specific indications like the systemic form of the disease,which requires antibiotic treatment. In the present article we are exposing a case report from Fundacion Cardioinfantil; we will review some epidemiologic aspects, clinical manifestations, diagnostic methods as well as imaging findings in Ultrasonography, Computed Tomography, Magnetic Resonance and Nuclear Medicine.

    Eosinophilic granulomatosis with polyangiitis (EGPA), which was previously called Churg-Strauss syndrome, is a necrotizing systemic vasculitis of unknown cause accompanied by prominent eosinophilia. Cardiovascular complications, including eosinophilic myocarditis, are a major cause of mortality in this disorder. Acute pericarditis with slight pericardial effusion is a typical manifestation in EGPA, though hemodynamically significant pericardial effusion has been reported in a few cases. We report a case that initially presented with isolated cardiac tamponade, which was followed by systemic manifestations of EGPA over 3 weeks. Including the present case, previous EGPA cases with cardiac tamponade are reviewed to delineate its clinical characteristics.

    This research examined the acute skin reaction of two consecutive groups receiving tangetial breast irradiation for carcinoma of the breast. The first group used the traditional skin care advice of using warm water only within the treatment area, while the second group continued with their normal skin care regime. Data was collected on the physical manifestations of the acute reaction, medical history, the use of concurrent cytotoxic agents, treatment parameters and skin care products used. Statistical analysis using the T-test method showed no difference in the skin reaction between the two groups. The investigation has lead to a change of policy in the management of acute breast reactions. Patients receiving radiation therapy to the breast or chest wall can now use their routine skin care products with no adverse effect on skin reactions. (author)

    To study the occurrence and types of neoplasms developed by patients who underwent an orthotopic cardiac transplantation under the Program of Cardiac Transplantation of Escola Paulista de Medicina, Federal University of São Paulo. This is an observational study of 106 patients who underwent orthotopic cardiac transplantation from November 1986 to September 2002 and survived at least thirty days following the procedure. The triple immunosuppressive regimen given included cyclosporin A, azathioprine and a corticosteroid agent. Only two patients received OKT3 in addition to the regimen established. Mean follow-up was 61.4 months (ranging from two months to 192 months). Twenty-three patients (21.3%) developed neoplasms--56.5% of these were skin neoplasm, 30.1%, solid tumors, and 13.4% of post-transplant lymphoproliferative disease (PTLD). Mean interval between transplantation and diagnosis of neoplasm was: 54.9 months for skin neoplasm; 24.8 months for solid tumors and 70.3 months for PTLD. Malignant neoplasms are relatively common in the population studied. Skin cancer was the most common type compared to the other types of neoplasms. Solid tumors were more frequently diagnosed than the lymphoproliferative diseases in the population examined.

  12. Exercise improves cardiac autonomic function in obesity and diabetes.

    Physical activity is a key element in the prevention and management of obesity and diabetes. Regular physical activity efficiently supports diet-induced weight loss, improves glycemic control, and can prevent or delay type 2 diabetes diagnosis. Furthermore, physical activity positively affects lipid profile, blood pressure, reduces the rate of cardiovascular events and associated mortality, and restores the quality of life in type 2 diabetes. However, recent studies have documented that a high percentage of the cardiovascular benefits of exercise cannot be attributed solely to enhanced cardiovascular risk factor modulation. Obesity in concert with diabetes is characterized by sympathetic overactivity and the progressive loss of cardiac parasympathetic influx. These are manifested via different pathogenetic mechanisms, including hyperinsulinemia, visceral obesity, subclinical inflammation and increased thrombosis. Cardiac autonomic neuropathy is an underestimated risk factor for the increased cardiovascular morbidity and mortality associated with obesity and diabetes. The same is true for the role of physical exercise in the restoration of the heart cardioprotective autonomic modulation in these individuals. This review addresses the interplay of cardiac autonomic function in obesity and diabetes, and focuses on the importance of exercise in improving cardiac autonomic dysfunction.

    Inherited ichthyoses are rare disorders in terms of patient numbers, but abundant in terms of clinical-genetic subtypes. These disorders are often associated with severe systemic manifestations, in addition to significant medical, cosmetic and social problems. There are 17 subtypes of syndromic ichthyosis identified so far and most patients with these syndromes are living in countries with high consanguinity rates. Frequently, clinicians cannot make a definitive diagnosis and patients are not managed properly owing to the rarity and complexity of these disorders. These difficulties make this group of ichthyosis and the patients living with them 'orphan'. After skin and skin appendages, nervous system is the most frequently involved system in ichthyosis syndromes. Thus, association of ichthyosis with neurological symptoms provides an important clue for diagnosis. In this article, we aim to increase clinicians' comprehension of ichthyosis syndromes by providing a symptomatology-based approach based on this observation. Additionally, we provide a review of ichthyosis syndromes, with special emphasis on neurological symptoms, hoping to attract interest to this complicated field. © 2016 John Wiley & Sons A/S.

    Purpose: To investigate the effect of proton beam therapy (PBT) on implanted cardiac pacemaker function. Methods and Materials: After a phantom study confirmed the safety of PBT in patients with cardiac pacemakers, we treated 8 patients with implanted pacemakers using PBT to a total tumor dose of 33-77 gray equivalents (GyE) in dose fractions of 2.2-6.6 GyE. The combined total number of PBT sessions was 127. Although all pulse generators remained outside the treatment field, 4 patients had pacing leads in the radiation field. All patients were monitored by means of electrocardiogram during treatment, and pacemakers were routinely examined before and after PBT. Results: The phantom study showed no effect of neutron scatter on pacemaker generators. In the study, changes in heart rate occurred three times (2.4%) in 2 patients. However, these patients remained completely asymptomatic throughout the PBT course. Conclusions: PBT can result in pacemaker malfunctions that manifest as changes in pulse rate and pulse patterns. Therefore, patients with cardiac pacemakers should be monitored by means of electrocardiogram during PBT

    Full Text Available Abstract Cardiac angiosarcomas are extremely rare in childhood, they are rapidly progressive tumours that often present themselves as diagnostic dilemmas, resulting in delayed diagnosis. Also, extracardiac manifestations, including abdominal pain, are extremely rare in patients with intracardiac tumors. We herein present the case of a 15-year-old girl who presented with abdominal pain. Echocardiography and thoracic computed tomography showed right atrial mass. The patient underwent surgery, chemotherapy, and radiotherapy. Eight months after treatment, abdominal recurrence was detected. The abdominal mass was resected, and radiotherapy and new chemotherapy protocol were given. The present case illustrates a rare case of primary cardiac angiosarcoma posing a diagnostic dilemma in an adolescent girl.

    The postoperative chest radiographic findings in 38 patients undergoing orthotopic (37 patients) and heterotopic (1 patient) cardiac transplantation were evaluated. Findings were correlated with those of echocardiograms, sputum and blood cultures, and lung and heart biopsies. The radiographic manifestations in the chest of these patients are classified in the following three main categories: 1) newly formed cardiac silhouette findings due to the transplanted heart itself, i.e., changes in size and shape of the new heart and pericardial effusion resulting from the placement of a smaller heart in a larger pericardial sac. 2) infectious complications due to bacteria, fungal, and other opportunistic agents secondary to immunosuppressive therapy, and 3) usual postoperatice complications following thoracomoty and open-heart surgery.

    Full Text Available Background: Cutaneous disorders during HIV infection are numerous and skin is often the first and only organ affected during most of the course of HIV disease. Some Cutaneous disorders reflect the progression of HIV disease; though the relation is still controversial. Aims : The objective of this study, conducted at a tertiary care centre in Bastar, Jagdalpur, is to estimate the status of cutaneous manifestation in HIV-infected patients and its relationship with CD4 cell counts. Methods: We enrolled 137 HIV positive subjects. Demographic information such as age, gender, weight, height, socioeconomic status, and educational status were recorded. Laboratory parameter (CD4 counts and treatment regimen were noted. Patients were examined for skin disorders by a dermatologist. Data were analyzed using chi-square test for categorical variables. Results: Majority of the patients were from rural area (65.69% and belonged to a low socioeconomic and educational status. 30.65% of the patients were housewives, 23.35% drivers, and 16.78% labourers. Predominant mode of transmission was heterosexual contact (94.16%. Most common HIV-related dermatological manifestations were seborrheic dermatitis (74.16%, xerosis (52.5%, generalized skin hyperpigmentation 56 (46.67%, onychomycosis 53 (44.16%, pruritic papular eruption 27 (22.5%, oral candidiasis 21 (17.5%, photo dermatitis 21 (17.5%, and scabies 4 (3.33%. Significant correlation with low CD4+ cell counts was found for oral candidiasis (P < 0.0001 and Kaposi′s sarcoma ( P = 0.03, while other disorders such as seborrheic dermatitis ( P = 0.22, xerosis ( P = 0.25, and onychomycosis (P = 0.08 were not statistically significant. Conclusion : This study showed high prevalence of dermatological manifestations in HIV-infected subjects, and they occur more frequently with progression of HIV and decline in immune functions. Therefore, early diagnosis and management of skin disorders can improve the quality of life of

    The hypothesis that reduced cardiac filling, as a result of lower body negative pressure (LBNP) and postexercise hypotension (PEH), would attenuate the reflex changes to heart rate (HR), skin blood flow (SkBF), and mean arterial pressure (MAP) normally induced by facial immersion was tested. The purpose of this study was to investigate the cardiovascular control mechanisms associated with apneic facial immersion during different cardiovascular challenges. Six subjects randomly performed 30-s apneic facial immersions in 6.0 +/- 1.2 degrees C water under the following conditions: 1) -20 mmHg LBNP, 2) +40 mmHg lower body positive pressure (LBPP), 3) during a period of PEH, and 4) normal resting (control). Measurements included SkBF at one acral (distal phalanx of the thumb) and one nonacral region of skin (ventral forearm), HR, and MAP. Facial immersion reduced HR and SkBF at both sites and increased MAP under all conditions (P filling during LBNP and PEH significantly attenuated the absolute HR nadir observed during the control immersion (P facial immersion can be attenuated when cardiac filling is compromised.

    Recently, several studies revealed a much higher prevalence of later onset Fabry disease (FD) than previously expected. It suggested that later onset FD might present as an important hidden health issue in certain ethnic or demographic populations in the world. However, the natural history of its phenotype has not been systemically investigated, especially the cardiac involvement. The study analyzed a large-scale newborn screening program for FD to understand the natural course of later onset FD. To date, 916,383 newborns have been screened for FD in Taiwan, including more than 1,200 individuals with the common, later onset IVS4+919G>A (IVS4) mutation. Echocardiography was performed in 620 adults with the IVS4 mutation to analyze the prevalence of left ventricular hypertrophy (LVH), and gadolinium-enhanced cardiac magnetic resonance imaging was performed in 129 patients with FD, including 100 IVS4 adults. LVH was observed in 67% of men and 32% of women older than 40 years. Imaging evidenced significant late gadolinium enhancement in 38.1% of IVS4 men and 16.7% of IVS4 women with the IVS4 mutation but without LVH. Seventeen patients underwent endomyocardial biopsies, which revealed significant globotriaosylceramide substrate accumulation in their cardiomyocytes. Significant cardiomyocyte substrate accumulation in IVS4 patients led to severe and irreversible cardiac fibrosis before development of LVH or other significant cardiac manifestations. Thus, it might be too late to start enzyme replacement therapy after the occurrence of LVH or other significant cardiac manifestations in patients with later onset FD. This study also indicated the importance of newborn screening for early detection of the insidious, ongoing, irreversible cardiac damage in patients with later onset FD.

    2002-01-01

    A conventional giant cell tumor of the proximal femur recurred twice locally and developed pulmonary nodules. The lung lesions were felt to be an example of ''benign'' metastases. Eight months after the initial presentation, the patient developed a single skin nodule on the contralateral leg. Histologic features of the skin nodule showed conventional giant cell tumor identical to the bone lesion. This nodule is a manifestation of arterial metastasis typical of any malignant tumor and seemingly contradicts the concept of ''benign '' metastasis. (orig.)

    A case of acute nonlymphocytic leukemia presenting as pericarditis is reported in a five-year-old boy. Initially, a clinical diagnosis of viral pericarditis was made, because the child did not demonstrate hematologic or clinical manifestations of leukemia. Acute undifferentiated or lymphocytic leukemia. Acute undifferentiated or lymphocytic leukemia was diagnosed one week after admission when his peripheral blood count became abnormal. The patient did not respond to vincristine and prednisone. When cytochemical evaluation indicated acute myelomonocytic leukemia, employment of cytosine arabinoside and 6-thioguanine was instituted and the child began to improve. Currently, he is still in good remission and has no evidence of recurrence of pericarditis, 1 1/2 years after his initial presentation. In reviewing the literature, we found 17 patients who had leukemic pericardial effusion with cardiac tamponade. There are three reported cases of young children with pericardial effusion as the initial manifestation of acute lymphocytic leukemia, but no reported cases due to nonlymphocytic leukemia, as in this child.

    2016-08-01

    Atopic dermatitis (AD) is the most common inflammatory skin disease in the industrialized world and has multiple causes. Over the past decade, data from both experimental models and patients have highlighted the primary pathogenic role of skin barrier deficiency in patients with AD. Increased access of environmental agents into the skin results in chronic inflammation and contributes to the systemic "atopic (allergic) march." In addition, persistent skin inflammation further attenuates skin barrier function, resulting in a positive feedback loop between the skin epithelium and the immune system that drives pathology. Understanding the mechanisms of skin barrier maintenance is essential for improving management of AD and limiting downstream atopic manifestations. In this article we review the latest developments in our understanding of the pathomechanisms of skin barrier deficiency, with a particular focus on the formation of the stratum corneum, the outermost layer of the skin, which contributes significantly to skin barrier function.

    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.

    Full Text Available Psoriasis is one of the most prevalent chronic inflammatory skin diseases. The severity of its clinical manifestations can vary greatly. Objective assessment of psoriasis severity is required to select an adequate therapy. One of the simplest and most consistent methods used to determine psoriasis severity is to calculate the PASI (Psoriasis Area and Severity Index. This index is based on the doctor’s determination of the sum of indices showing the intensity of the main symptoms of psoriasis: erythema, infiltration and peeling in view of the affected skin area. The PASI can also be used to assess the efficacy of treatment for psoriasis patients.

    The synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome includes a group of chronic, relapsing, inflammatory musculoskeletal disorders with similar manifestations, in particular synovitis, hyperostosis, and osteitis, which may or may not be associated with neutrophilic skin eruptions such as palmoplantar pustulosis and acne conglobata. The syndrome occurs at any age, can involve any skeletal site, and its imaging appearances are variable, depending on the stage/age of the lesion and imaging method. The diagnosis is difficult if there is no skin disease. Awareness of the imaging appearances, especially in the spine, may help the radiologist in avoiding misdiagnosis (e.g., infection, tumor) and unnecessary invasive procedures, while facilitating early diagnosis and selection of an effective treatment. In this article, we provide an overview of the radiological appearances of SAPHO syndrome, focusing on the magnetic resonance imaging findings of vertebral involvement, and present relevant clinical and pathological features that assist early diagnosis.

The syndrome occurs at any age, can involve any skeletal site, and its imaging appearances are variable, depending on the stage/age of the lesion and imaging method. The diagnosis is difficult if there is no skin disease. Awareness of the imaging appearances, especially in the spine, may help the radiologist in avoiding misdiagnosis (e.g., infection, tumor) and unnecessary invasive procedures, while facilitating early diagnosis and selection of an effective treatment. In this article, we provide an overview of the radiological appearances of SAPHO syndrome, focusing on the magnetic resonance imaging findings of vertebral involvement, and present relevant clinical and pathological features that assist early diagnosis.

    Full Text Available Cirrhosis and hepatocellular carcinoma are the prototypic complications of chronic hepatitis C virus infection in the liver. However, hepatitis C virus also affects a variety of other organs that may lead to significant morbidity and mortality. Extrahepatic manifestations of hepatitis C infection include a multitude of disease processes affecting the small vessels, skin, kidneys, salivary gland, eyes, thyroid, and immunologic system. The majority of these conditions are thought to be immune mediated. The most documented of these entities is mixed cryoglobulinemia. Morphologically, immune complex depositions can be identified in small vessels and glomerular capillary walls, leading to leukoclastic vasculitis in the skin and membranoproliferative glomerulonephritis in the kidney. Other HCV-associated entities include porphyria cutanea tarda, lichen planus, necrolytic acral erythema, membranous glomerulonephritis, diabetic nephropathy, B-cell non-Hodgkin lymphomas, insulin resistance, sialadenitis, sicca syndrome, and autoimmune thyroiditis. This paper highlights the histomorphologic features of these processes, which are typically characterized by chronic inflammation, immune complex deposition, and immunoproliferative disease in the affected organ.

    Many radiation injuries to the skin, resulting from diagnostic and interventional fluoroscopic procedures, have been reported in recent years. In some cases skin damage was severe and debilitating. We analyzed 72 reports of skin injuries for progression and location of injury, type and number of procedures, and contributing patient and operator factors. Most cases (46) were related to coronary angiography and percutaneous transluminal coronary angioplasty (PTCA). A smaller number was documented after cardiac radiofrequency catheter ablation (12), transjugular intrahepatic portosystemic shunt (TIPS) placement (7), neuroradiological interventions (3) and other procedures (4). Important factors leading to skin injuries were long exposure times over the same skin area, use of high dose rates, irradiation through thick tissue masses, hypersensitivity to radiation, and positioning of arms or breasts into the radiation entrance beam. Physicians were frequently unaware of the high radiation doses involved and did not recognize the injuries as radiation induced. Based on these findings, recommendations to reduce dose and improve patient care are provided. (author)

    Previous studies have demonstrated the feasibility of detecting canine heterotopic cardiac allograft rejection scintigraphically after administration of 111In lymphocytes. To determine whether the approach is capable of detecting rejection in orthotopic cardiac transplants in which labeled lymphocytes circulating in the blood pool may reduce sensitivity, the present study was performed in which canine orthotopic cardiac transplants were evaluated in vivo. Immunosuppression was maintained with cyclosporine A (10-20 mg/kg/day) and prednisone (1 mg/kg/day) for 2 wk after transplantation. Subsequently, therapy was tapered. Five successful allografts were evaluated scintigraphically every 3 days after administration of 100-350 microCi 111In autologous lymphocytes. Correction for labeled lymphocytes circulating in the blood pool, but not actively sequestered in the allografts was accomplished by administering 3-6 mCi 99mTc autologous erythrocytes and employing a previously validated blood-pool activity correction technique. Cardiac infiltration of labeled lymphocytes was quantified as percent indium excess (%IE), scintigraphically detectable 111In in the transplant compared with that in blood, and results were compared with those of concomitantly performed endomyocardial biopsy. Scintigraphic %IE for hearts not undergoing rejection manifest histologically was 0.7 +/- 0.4. Percent IE for rejecting hearts was 6.8 +/- 4.0 (p less than 0.05). Scintigraphy detected each episode of rejection detected by biopsy. Scintigraphic criteria for rejection (%IE greater than 2 s.d. above normal) were not manifest in any study in which biopsies did not show rejection. Since scintigraphic results with 111In-labeled lymphocytes were concordant with biopsy results in orthotopic cardiac transplants, noninvasive detection of graft rejection in patients should be attainable with the approach developed

    Full Text Available Skin pigmentation is one of the most strikingly variable phenotypes in humans, therefore making cutaneous pigmentation disorders frequent symptoms manifesting in a multitude of forms. The most common among them include lentigines, postinflammatory hyperpigmentation, dark eye circles, and melasma. Variability of skin tones throughout the world is well-documented, some skin tones being reported as more susceptible to pigmentation disorders than others, especially in Asia and India. Furthermore, exposure to ultraviolet radiation is known to trigger or exacerbate pigmentation disorders. Preventive strategies for photoprotection and treatment modalities including topical and other medical approaches have been adopted by dermatologists to mitigate these disorders. This review article outlines the current knowledge on pigmentation disorders including pathophysiology, molecular profiling, and therapeutic options with a special focus on the Indian population.

  17. Deep Vein Thrombosis as Initial Manifestation of Whipple Disease

    Directory of Open Access Journals (Sweden)

    Mônica Souza de Miranda Henriques

    2016-11-01

    Full Text Available Introduction: Wipple disease (WD is a rare chronic disease caused by the bacillus Tropheryma whipplei. Constitutive, rheumatologic, gastrointestinal, cardiac, cerebral, lymphatic, cutaneous, and ophthalmological signs are possible systemic symptoms. However, thrombotic manifestations are rarely described as “stroke-like syndrome” or arterial thrombosis. Diagnosis is based on clinical manifestations and pathological examination. Laboratory findings may include anemia, leukocytosis, and thrombocytosis. Objective: We report a case of venous thrombosis as initial manifestation of WD. Case Report: We describe the case of a 53-year-old male with iliofemoral vein thrombosis followed by intermittent diarrhea, loss of appetite, abdominal distension, and bloating. A mild malnutrition state with a weight loss of 13 kg, pallor (+/4 +, presence of lower-limb edema (+/4 +, and hypertympanic distended abdomen occurred. Laboratory tests on admission revealed anemia, positive inflammatory activity tests, and normal coagulation. Endoscopic examination showed villous edema with white dotted infiltrates in the second duodenal portion and intestinal lymphangiectasia in the terminal ileum. Pathological examination revealed numerous macrophages with positive periodic acid-Schiff inclusions. Venous Doppler ultrasound showed extensive deep thrombosis on the left lower limb and recanalization of the femoral vein in the right lower limb. The patient was treated with ceftriaxone and enoxaparin sodium, which led to an improvement of gastrointestinal and thrombosis symptoms. Comments: Hypercoagulability, endothelial damage, vasculitis, and blood stasis are present in T. whipplei infection, which are associated with the activation of inflammatory mechanisms as well as procoagulant and thromboembolic events. WD should be part of the differential diagnosis of diseases that cause venous thrombosis of unknown origin.

    The skin senses serve a discriminative function, allowing us to manipulate objects and detect touch and temperature, and an affective/emotional function, manifested as itch or pain when the skin is damaged. Two different classes of nerve fibre mediate these dissociable aspects of cutaneous somatosensation: (i) myelinated A-beta and A-delta afferents that provide rapid information about the location and physical characteristics of skin contact; and (ii) unmyelinated, slow-conducting C-fibre afferents that are typically associated with coding the emotional properties of pain and itch. However, recent research has identified a third class of C-fibre afferents that code for the pleasurable properties of touch - c-tactile afferents or CTs. Clinical application of treatments that target pleasant, CT-mediated touch (such as massage therapy) could, in the future, provide a complementary, non-pharmacological means of treating both the physical and psychological aspects of chronic skin conditions such as itch and eczema. © 2015 John Wiley & Sons A/S.

    The cardiac safety of cetuximab and panitumumab, particularly as single agents, has not been investigated extensively. This trial was designed to specifically evaluate the cardiac safety of cetuximab and panitumumab as single therapy in Chinese chemotherapy-refractory metastatic colorectal cancer (mCRC) patients. Sixty-one patients received cetuximab at an initial dose of 400 mg/m 2 intravenously over 120 minutes on day 1 (week 1), followed by a maintenance dose of 250 mg/m 2 intravenously over 60 minutes on day 1 of each 7-day cycle. Forty-three patients received panitumumab at a dose of 6 mg/kg intravenously every 14 days. Routine laboratory tests and electrocardiogram (ECG) were performed at baseline, during therapy and after the treatment (4th and 10th months). The incidence of elevation of troponin I ultra (TNI Ultra), abnormal ECGs, cardiac events and noncardiac adverse events (AEs) were recorded and analyzed. The incidence of elevation of TNI Ultra between the two groups had no significance ( p =0.681), and TNI Ultra+ was observed more frequently in patients with metastases to more than three organs and they received fourth or above lines of chemotherapy. The most frequent abnormal ECG manifestations were nonspecific ST changes and QTc prolongation in the two groups. At 10 months after treatment, most of the abnormal ECG manifestations were reversed. The most common cardiac AEs of cetuximab and panitumumab included palpitations, dyspnea, chest pain and arrhythmias requiring treatment. Most of the events were mild and transient. The incidence of cardiac AEs had no significant difference between the two groups. Rash was still the most common noncardiac AE in both groups. Cetuximab and panitumumab showed favorable cardiac safety as single agents for Chinese chemotherapy-refractory mCRC patients. But monitoring for cardiac AEs is still necessary throughout the entire treatment process.

    : The modern conveniences and enjoyment brought about by electronic devices bring with them some health concerns. In particular, personal electronic devices are responsible for rising cases of several skin disorders, including pressure, friction, contact dermatitis, and other physical dermatitis. The universal use of such devices, either for work or recreational purposes, will probably increase the occurrence of polymorphous skin manifestations over time. It is important for clinicians to consider electronics as potential sources of dermatological ailments, for proper patient management. We performed a literature review on skin disorders associated with the personal use of modern technology, including personal computers and laptops, personal computer accessories, mobile phones, tablets, video games, and consoles.

    Acral peeling skin syndrome is a rare autosomal recessive disorder in which skin exfoliation is limited to the hands and feet. While it typically manifests from early childhood, in this first reported case from South Africa, the patient did not manifest clinically until the fourth decade of life. A 44-year-old woman of African descent, 1 of a set of non-identical twins, presented with recurrent episodes of skin peeling of the upper and lower limbs. The first episode occurred 4 years prior, followed by perennial skin peeling during the spring seasons. She was not on treatment for any chronic disease and reported no exposure to chemicals or other irritants. The family, including the non-identical twin sister, has no history of skin disorders and the patient's HIV antibody test was negative. At presentation, physical examination revealed ongoing exfoliation with new skin formation on the palms and soles. The mucous membranes and nails were spared. Other systems were normal. Skin biopsy taken from the palms confirmed peeling skin syndrome. The patient was managed with topical aqueous cream and analgesics. She was briefly counseled on the nature and prognosis of the disease, and referred for genetic testing and counseling. On follow-up, she continues to have skin peeling once or twice a year. This first reported case of this rare disease in South Africa contributes to the growing body of literature on the disease and highlights the need for clinicians to be aware of its variable clinical onset.

    Hypertension is a common cardiovascular risk factor leading to heart failure (HF), coronary artery disease, stroke, peripheral artery disease and chronic renal insufficiency. Hypertensive heart disease can manifest as many cardiac arrhythmias, most commonly being atrial fibrillation (AF). Both...... supraventricular and ventricular arrhythmias may occur in hypertensive patients, especially in those with left ventricular hypertrophy (LVH) or HF. Also, some of the antihypertensive drugs commonly used to reduce blood pressure, such as thiazide diuretics, may result in electrolyte abnormalities (e.g. hypokalaemia......, hypomagnesemia), further contributing to arrhythmias, whereas effective control of blood pressure may prevent the development of the arrhythmias such as AF. In recognizing this close relationship between hypertension and arrhythmias, the European Heart Rhythm Association (EHRA) and the European Society...

    Stenotrophomas maltophilia is an opportunistic Gram-negative bacillus and an important cause of nosocomial infections, particularly in immunosuppressed individuals. Although infections with this organism are most often in the form of pneumonia, bacteremia and endocarditis, awareness of the impact of S. maltophilia skin infections has been increasing. Here we describe a case of S. maltophilia cellulitis in a 65-year-old man with severe neutropenia and purpuric skin lesions to highlight the critical histopathological findings and correlate them with the clinical manifestations of the skin infection with this organism. Because identification of S. maltophilia can be challenging and infections are difficult to manage, this case illustrates essential considerations regarding the multifaceted histopathological, dermatological, clinical and microbiological aspects of the diagnosis and treatment of S. maltophilia cellulitis in a severely immunocompromised patient. Cognizance of the increasing incidence of nosocomial infections with uncommon microorganisms such as S. maltophilia is necessary when presented with atypical cutaneous manifestations, particularly in immunocompromised patients. © 2016 John Wiley & Sons A/S.

    Objective: To describe the clinical and imaging manifestations of patients with synovitis acne pustulosis hyperostosis osteomyelitis (SAPHO) syndrome, and to analyze the diagnostic importance of different clinical and imaging manifestations for SAPHO syndrome. Methods: Seventeen patients (7 males and 10 females) with SAPHO syndrome were recruited in this study. Age ranged from 36 to 67 years with a mean age of (48 ± 8) years. All patients fulfilled the diagnostic criteria of Benhamou. Serum HLA B27 antigen records were reviewed for all patients. Imaging data of the abnormal bone sites were collected by conventional radiograph in all patients, CT in 13 patients as well as MR in 3 patients. Average time to take for a definite diagnosis of the syndrome was 3.7 years (ranged from O.5 to 13 years). Results: Serum HLA B27 antigen was positive in all patients. Both skin and bone abnormalities were found in all patients. Ten patients had skin palmoplantar pustulosis and two patients had acne. Involving sites of bone and joints include sacroiliac joints, anterior chest and limbs. Sacroiliac joints were asymmetrically involved with imaging features in all patients. Eight patients exhibited anterior chest wall involvement. Five patients had osteomyelitis at limbs. For all images of 17 patients, CT was superior to conventional radiography in detecting abnormal changes of bone erosion and soft tissue swelling. MR imaging was able to depict edema changes that was not detectable by CT and radiography. Conclusion: SAPHO syndrome is a rare disease, but for patients with skin and bone-joint abnormalities, especially with skin palmoplantar pustulosis, acne as well as with imaging features at the sacroiliac joint and anterior chest wall, SAPHO syndrome should be taken into a diagnostic consideration.

    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.

    For many years, ECG`s and vector cardiograms have been the tools of choice for non-invasive diagnosis of cardiac conduction problems, such as found in reentrant tachycardia or Wolff-Parkinson-White (WPW) syndrome. Through skillful analysis of these skin-surface measurements of cardiac generated electric currents, a physician can deduce the general location of heart conduction irregularities. Using a combination of high-fidelity geometry modeling, advanced mathematical algorithms and massively parallel computing, Sandia`s approach would provide much more accurate information and thus allow the physician to pinpoint the source of an arrhythmia or abnormal conduction pathway.

    Clinical and histologic stigmata of aging are much more prominent in habitually sun-exposed skin than in sun-protected skin, but other possible manifestations of actinically induced aging are almost unexplored. We have examined the interrelation of chronologic and actinic aging using paired preauricular (sun-exposed) and postauricular (sun-protected) skin specimens. Keratinocyte cultures derived from sun-exposed skin consistently had a shorter in vitro lifespan but increased plating efficiency compared with cultures derived from adjacent sun-protected skin of the same individual, confirming a previous study of different paired body sites. Electron microscopic histologic sections revealed focal abnormalities of keratinocyte proliferation and alignment in vitro especially in those cultures derived from sun-exposed skin and decreased intercellular contact in stratified colonies at late passage, regardless of donor site. One-micron histologic sections of the original biopsy specimens revealed no striking site-related keratinocyte alterations, but sun-exposed specimens had fewer epidermal Langerhans cells (p less than 0.001), averaging approximately 50 percent the number in sun-protected skin, a possible exaggeration of the previously reported age-associated decrease in this cell population. These data suggest that sun exposure indeed accelerates aging by several criteria and that, regardless of mechanism, environmental factors may adversely affect the appearance and function of aging skin in ways amenable to experimental quantitation

    The pathogenesis of left ventricular hypertrophy in patients with CKD is incompletely understood. Sodium intake, which is usually assessed by measuring urinary sodium excretion, has been inconsistently linked with left ventricular hypertrophy. However, tissues such as skin and muscle may store sodium. Using 23 sodium-magnetic resonance imaging, a technique recently developed for the assessment of tissue sodium content in humans, we determined skin sodium content at the level of the calf in 99 patients with mild to moderate CKD (42 women; median [range] age, 65 [23-78] years). We also assessed total body overhydration (bioimpedance spectroscopy), 24-hour BP, and left ventricular mass (cardiac magnetic resonance imaging). Skin sodium content, but not total body overhydration, correlated with systolic BP ( r =0.33, P =0.002). Moreover, skin sodium content correlated more strongly than total body overhydration did with left ventricular mass ( r =0.56, P skin sodium content is a strong explanatory variable for left ventricular mass, unaffected by BP and total body overhydration. In conclusion, we found skin sodium content to be closely linked to left ventricular mass in patients with CKD. Interventions that reduce skin sodium content might improve cardiovascular outcomes in these patients. Copyright © 2017 by the American Society of Nephrology.

    Full Text Available The aim of the proposed study is to demonstrate the benefits of using specialized cosmetic products as part of basic skin care for children with Atopic Dermatitis (AD. The epidermal barrier dysfunction is known to be the leading factor in pathogenesis of atopic dermatitis and it manifests as dry skin, imbalance in the composition of lipids of the stratum corneum and water-lipid mantle and alterations in the activity of proteases. Due to xerosis, the skin gets easily affected by allergens, irritants and pathogenic microorganisms, which triggers the "itch-scratch" cycle and can lead to AD exacerbation and significantly deteriorate the quality of life of the patient. The basic skin care using the moisturizing and soothing cosmetic products (emollients is acknowledged by all major Guidelines for treatment of AD as an important part of therapy. Significant improvements in skin status as well as the child's well-being can be achieved with use of this simple to understand skin care algorithm that includes proper skin cleansing, moisturizing and itch prevention.

    2012-01-01

    Ehlers-Danlos syndrome, hypermobility type, constituting a phenotypic continuum with or, perhaps, corresponding to the joint hypermobility syndrome (JHS/EDS-HT), is likely the most common, though the least recognized, heritable connective tissue disorder. Known for decades as a hereditary condition with predominant rheumatologic manifestations, it is now emerging as a multisystemic disorder with widespread manifestations. Nevertheless, the practitioners' awareness of this condition is generally poor and most patients await years or, perhaps, decades before reaching the correct diagnosis. Among the various sites of disease manifestations, skin and mucosae represent a neglected organ where the dermatologist can easily spot diagnostic clues, which consistently integrate joint hypermobility and other orthopedic/neurologic manifestations at physical examination. In this paper, actual knowledge on JHS/EDS-HT is summarized in various sections. Particular attention has been posed on overlooked manifestations, including cutaneous, mucosal, and oropharyngeal features, and early diagnosis techniques, as a major point of interest for the practicing dermatologist. Actual research progresses on JH/EDS-HT envisage an unexpected link between heritable dysfunctions of the connective tissue and a wide range of functional somatic syndromes, most of them commonly diagnosed in the office of various specialists, comprising dermatologists.

    Non-Hodgkin lymphoblastic lymphomas are very uncommon tumors that rarely involve the heart; however, when they do, they typically cause cardiac symptoms. Herein, we describe the case of a young woman who presented with respiratory symptoms. These were caused by a high-grade lymphoblastic lymphoma, which originated in the left inferior pulmonary vein and extended into the left atrium. The tumor was surgically debulked, but it recurred in 1 month, and the patient underwent chemotherapy. Six months later, she had recurrent respiratory symptoms, and echocardiography revealed a persistent mass in the left lower lobar vein. A modified chemotherapy regimen led to complete resolution of the tumor within 2 months. We are unaware of other reports of a primary cardiac non-Hodgkin lymphoblastic lymphoma with this unusual site of origin and rare manifestation of symptoms. PMID:21841872

    Feline allergic skin disease presents a unique set of challenges to the veterinary practitioner. Although there is some similarity to what is seen in the allergic canine patient, cutaneous hypersensitivity dermatoses in cats can manifest with strikingly different clinical signs, treatment options and outcomes, and secondary complications/disease entities. Additionally, less is known about the pathogenesis of feline allergic skin diseases, particularly “feline atopic syndrome” when compared to...

    Castori, Marco; C. Voermans, Nicol

    2014-01-01

    The term “Ehlers-Danlos syndrome” (EDS) groups together an increasing number of heritable connective tissue disorders mainly featuring joint hypermobility and related complications, dermal dysplasia with abnormal skin texture and repair, and variable range of the hollow organ and vascular dysfunctions. Although the nervous system is not considered a primary target of the underlying molecular defect, recently, increasing attention has been posed on neurological manifestations of EDSs, such as musculoskeletal pain, fatigue, headache, muscle weakness and paresthesias. Here, a comprehensive overview of neurological findings of these conditions is presented primarily intended for the clinical neurologist. Features are organized under various subheadings, including pain, fatigue, headache, stroke and cerebrovascular disease, brain and spine structural anomalies, epilepsy, muscular findings, neuropathy and developmental features. The emerging picture defines a wide spectrum of neurological manifestations that are unexpectedly common and potentially disabling. Their evaluation and correct interpretation by the clinical neurologist is crucial for avoiding superfluous investigations, wrong therapies, and inappropriate referral. A set of basic tools for patient’s recognition is offered for raising awareness among neurologists on this underdiagnosed group of hereditary disorders. PMID:25632331

    As the largest organ in the human body, the skin has multiple functions of which one of the most important is the protection against various harmful stressors. The keratinised stratified epidermis and an underlying thick layer of collagen-rich dermal connective tissues are important components of the skin. The environmental stressors such as ultraviolet radiation (UVR) and pollution increase the levels of reactive oxygen species (ROS), contributing to clinical manifestations such as wrinkle formation and skin aging. Skin aging is related to the reduction of collagen production and decrease of several enzymatic activities including matrix metalloproteinases (MMPs), which degrade collagen structure in the dermis; and tissue inhibitor of metalloproteinases (TIMPs), which inhibit the action of MMPs. In addition to alterations of DNA, signal transduction pathways, immunology, UVR, and pollution activate cell surface receptors of keratinocytes and fibroblasts in the skin. This action leads to a breakdown of collagen in the extracellular matrix and a shutdown of new collagen synthesis. Therefore, an efficient antioxidants strategy is of major importance in dermis and epidermis layers. Marine resources have been recognised for their biologically active substances. Among these, marine algae are rich-sources of metabolites, which can be used to fight against oxidative stress and hence skin aging. These metabolites include, among others, mycosporine-like amino acids (MAAs), polysaccharides, sulphated polysaccharides, glucosyl glycerols, pigments, and polyphenols. This paper reviews the role of oxidative processes in skin damage and the action of the compounds from algae on the physiological processes to maintain skin health.

    The Koebner phenomenon originally described the appearance of psoriatic lesions in the uninvolved skin of patients with psoriasis as a consequence of trauma. We describe a case of concurrent lichen planus and sarcoidosis in the auditory canal, which represents an unusual manifestation of the Koebner phenomenon. This is the first case of concurrent lichen planus and sarcoidosis in the head and neck region and highlights the need for biopsy to allow accurate histopathological diagnosis and treatment.

    Newman-Toker, David E; Camargo, Carlos A

    2006-03-01

    A 90-year-old woman presented to a hospital emergency department with a brief loss of consciousness that was heralded by spinning vertigo lasting approximately 2 min. She had a long history of intermittent brief episodes of rotatory vertigo, presyncope, and non-vertiginous dizziness, occurring either with or without loss of consciousness. Although initially attributed to symptomatic carotid artery stenosis, these episodes persisted, despite surgical restoration of carotid artery blood flow 1 year after her first syncope. Her medical history was otherwise notable for hypertension, mild depression and a gradual decline in gait and balance function attributed to left hip arthritis and older age. Bedside history and examination, non-contrast head CT scan, electrocardiogram, transthoracic echocardiogram, and bedside cardiac telemetry. Sick sinus syndrome or severe reflex bradycardia with asystole causing recurrent, episodic vertigo, presyncope, non-vertiginous dizziness and syncope (Stokes-Adams attacks). Placement of a temporary pacing wire, followed by surgical implantation of a single-chamber ventricular (VVI) pacemaker.

    Familial Mediterranean fever (FMF) is a hereditary disease characterized by brief, recurring and self-limited episodes of fever and pain with inflammation, of one or several serous (peritoneum, pleura, pericardium, synovial or vaginal tunic of the testicle). Amyloidosis is its more important complication and the principal reason of death in the cases in which it appears. Diagnosis is based on the clinic and is confirmed by genetic tests. The treatment with Colchicine (0,02-0,03 mg/kg/day) prevents the recurrence of FMF attacks and the development of secondary (AA) amyloidosis. We report a case of a 13-year-old child in which FMF was diagnosed after several coincidental episodes with fever, pericarditis and cardiac tamponade. The genetic confirmation showed an autosomal dominant inheritance that is less frecuent than the recesive form, in this disease. Copyright © 2013 Asociación Española de Pediatría.

    We discuss the cardiac 123 I-MIBG ( 123 I-metaiodobenzylguanidine) scintigraphy in patients with Parkinson's disease (PD) based on our results, and examine the clinical significance in lowering MIBG storage. Thirty-four patients with PD without diabetes millitus or heart failure, presenting normal cardiac thallium scintigraphy, were examined. They included 13 male and 21 female, aged from 52 to 83 (average age 70.1) and their morbid period was between 0.25 and 19 years (agerage 4.9 years). Ten patients with age-matched disease control were chosen. They contained 5 male and 5 female, aged from 59 to 77 (average age 70.7), suffering from headache, vertigo, cerebral infarction, etc. PD patients group and the age-matched control group were compared with the normal control group. In PD patients, MIBG storage was significantly lowered on the initial and the late images in comparison with the disease and neurological control groups, and the wash-out rate was enhanced. There was negative correlation or the expected tendency of correlation between MIBG storage and the clinical severity. MIBG storage was lowered with longer morbid period. Anti-Parkinson drugs had no apparent effects on MIBG storage. The detection rate of abnormality by cardiac MIBG scintigraphy was clearly higher than that by the sympathetic skin response, and some patients who had no sign on the sympathetic skin response showed the lowering of MIBG storage. The possibility of the failure of the norepinephrine transporter system was indicated as the main cause for the lowering of MIBG storage. (K.H.)

    Full Text Available Huntington's disease (HD is an inherited neurodegenerative disorder typified by involuntary body movements, and psychiatric and cognitive abnormalities. Many HD patients also exhibit metabolic changes including progressive weight loss and appetite dysfunction. Here we have investigated metabolic function in pre-manifest and manifest HD subjects to establish an HD subject metabolic hormonal plasma signature. Individuals at risk for HD who have had predictive genetic testing showing the cytosine-adenine-guanine (CAG expansion causative of HD, but who do not yet present signs and symptoms sufficient for the diagnosis of manifest HD are said to be pre-manifest. Pre-manifest and manifest HD patients, as well as both familial and non-familial controls, were evaluated for multiple peripheral metabolism signals including circulating levels of hormones, growth factors, lipids and cytokines. Both pre-manifest and manifest HD subjects exhibited significantly reduced levels of circulating growth factors, including growth hormone and prolactin. HD-related changes in the levels of metabolic hormones such as ghrelin, glucagon and amylin were also observed. Total cholesterol, HDL-C and LDL-C were significantly decreased in HD subjects. C-reactive protein was significantly elevated in pre-manifest HD subjects. The observation of metabolic alterations, even in subjects considered to be in the pre-manifest stage of HD, suggests that in addition, and prior, to overt neuronal damage, HD affects metabolic hormone secretion and energy regulation, which may shed light on pathogenesis, and provide opportunities for biomarker development.

  5. Pygmy quadrupole resonance as a manifestation of the nuclear skin

    Recently, a new mode of nuclear excitation called pygmy quadrupole resonance (PQR) was theoretically predicted in the framework of energy-density functional (EDF) theory plus three-phonon quasiparticle-phonon model (QPM) in Sn isotopic chain. It is closely connected with higher order multipole vibrations of nuclear skin induced by the action of the electromagnetic and hadronic external fields. The predictions initiated new experiments using ({sup 17}O,{sup 17}O{sup '}γ), (α,α{sup '}γ) and (γ,γ{sup '}) reactions which were carried out in {sup 124}Sn nucleus. The aim was to probe for the first time experimentally, the possibility of existence of PQR. The detailed analysis of the obtained experimental results in comparison with the EDF+QPM theory indicates clearly the presence of a multitude of discrete low-energy 2{sup +} excitations of neutron type which can be addressed to PQR mode. The independent measurements of B(E2) values with different probes and the theory allow to identify the dominant isoscalar character of these states. Furthermore, newly determined γ-decay branching ratios exclude a statistical origin of the PQR strength. The latter are important to discriminate between PQR and multiphonon excitations.

    Onchocerciasis is caused by Onchocerca volvulus and mainly leads to pruritus and skin and visual disorders, including blindness. Seventeen million people are infected in 38 countries; 31 of these are in sub-Saharan Africa, six in Latin America and one on the Arabian Peninsula. More than 99% of cases occur in sub-Saharan Africa where 120 million people are at risk of infection. Eye disorders have been well-documented; however, skin disorders have not been described accurately. The objective of our study was to describe the epidemiology, main skin manifestations and treatment of imported onchocerciasis. A retrospective study was thus conducted by analysing the main demographic, clinical and treatment data regarding a cohort of 400 patients attending a reference clinical unit over a 17-year period. Most patients were female (55%) with mean age 37.5±16.7 years. All the migrants came from sub-Saharan countries. The most frequently occurring dermatological symptom was pruritus. Ivermectin had been used as first-line therapy and adverse reactions had been described in 11 patients (3.2%). The results indicate the fact that there should be a clinical suspicion of onchocerciasis regarding immigrants from endemic areas having skin lesions compatible with the disease's profile or asymptomatic patients having eosinophilia or unexplained high IgE. Moreover, skin snips from the buttocks region were very fruitful and treatment with ivermectin was seen to be safe. This is the largest case series regarding imported onchocerciasis described up to the present time.

    The presence, degree and frequency of disorders of cardiac conduction and rhythm and of regional or global myocardial dystrophy or myotonia have not previously been studied prospectively and systematically in the same population of patients with myotonic dystrophy. Accordingly, 25 adults with classic Steinert's disease underwent electrocardiography, 24-hour ambulatory electrocardiography, vectorcardiography, chest x-rays, echocardiography, electrophysiologic studies, and technetium-99m angiography. Clinically important cardiac manifestations of myotonic dystrophy reside in specialized tissues rather than in myocardium. Involvement is relatively specific, primarily assigned to the His-Purkinje system. The cardiac muscle disorder takes the form of dystrophy rather than myotonia, and is not selective, appearing with approximately equal distribution in all 4 chambers. Myocardial dystrophy seldom results in clinically overt ventricular failure, but may be responsible for atrial and ventricular arrhythmias. Since myotonic dystrophy is genetically transmitted, a primary biochemical defect has been proposed with complete expression of the gene toward striated muscle tissue, whether skeletal or cardiac. Specialized cardiac tissue and myocardium have close, if not identical, embryologic origins, so it is not surprising that the genetic marker affects both. Cardiac involvement is therefore an integral part of myotonic dystrophy, targeting particularly the infranodal conduction system, to a lesser extent the sinus node, and still less specifically, the myocardium

    Streptococcus suis is a bacterium causing a disease in pigs and rarely in humans. This zoonosis is mostly found as a sporadic disease in individuals that were in contact with the affected or infected pigs: farmers, veterinarians and workers engaged in fresh pork processing. It is assumed that the bacterium enters the body through a cut abrasion in the skin. Initially, the condition resembles a flu, followed by signs of bacteriemia and sepsis. The most frequent clinical manifestation of Streptococcus suis infection is meningitis, leading to hearing loss in over 75% of patients, and subsequent arthritis, endophtalmitis, endocarditis and pneumonia. Toxic shock syndrome with hemorhagic manifestations rarely develops. This study included five male patients aged 22 to 63 years treated in the Intensive Care Unit of the Institute of Infectious and Tropical Diseases in Belgrade, due to Streptococcus suis infection. The aim of this study was to point to the existence of this bacteria in our environment, to describe clinical manifestations of the disease and to point out the importance of its prevention. All patients had epidemiological evidence of being in contact with pork meat. There were no data about diseased pigs. The estimated incubation period was 4 to 8 days. All patients had meningeal signs. Clinical symptoms included shivering, fever, vomiting, headache, malaise, vertigo and tinitus. Three patients presented with alerterd level of awarrness. Four patients developed very severe bilateral hearing impairment, whereas one endophtalmtis and one developed endocarditis. The cerebrospinal fluid (CSF) was opalescent in four patients, and only one patient presented with clear CSF. CSF examination showed typical changes characteristic for bacterial meningitis. Streptoccocus suis was isolated in CSF in all patients, and in one patient the bacteria was isolated in blood as well. All patients underwent treatement with II and III generation cephalosporins and one with one

    Mammalian enabled (Mena) of the Drosophila enabled/vasodilator-stimulated phosphoprotein gene family is a cytoskeletal protein implicated in actin regulation and cell motility. Cardiac Mena expression is enriched in intercalated discs (ICD), the critical intercellular communication nexus between adjacent muscle cells. We previously identified Mena gene expression to be a key predictor of human and murine heart failure (HF). To determine the in vivo function of Mena in the heart, we assessed Mena protein expression in multiple HF models and characterized the effects of genetic Mena deletion on cardiac structure and function. Immunoblot analysis revealed significant upregulation of Mena protein expression in left ventricle tissue from patients with end-stage HF, calsequestrin-overexpressing mice, and isoproterenol-infused mice. Characterization of the baseline cardiac function of adult Mena knockout mice (Mena(-/-)) via echocardiography demonstrated persistent cardiac dysfunction, including a significant reduction in percent fractional shortening compared with wild-type littermates. Electrocardiogram PR and QRS intervals were significantly prolonged in Mena(-/-) mice, manifested by slowed conduction on optical mapping studies. Ultrastructural analysis of Mena(-/-) hearts revealed disrupted organization and widening of ICD structures, mislocalization of the gap junction protein connexin 43 (Cx43) to the lateral borders of cardiomyoycytes, and increased Cx43 expression. Furthermore, the expression of vinculin (an adherens junction protein) was significantly reduced in Mena(-/-) mice. We report for the first time that genetic ablation of Mena results in cardiac dysfunction, highlighted by diminished contractile performance, disrupted ICD structure, and slowed electrical conduction.

    Full Text Available Dermatitis herpetiformis (DH is a rare autoimmune disease linked to gluten sensitivity with a chronic-relapsing course. It is currently considered to be the specific cutaneous manifestation of celiac disease (CD. Both conditions are mediated by the IgA class of autoantibodies, and the diagnosis of DH is dependent on the detection of granular deposits of IgA in the skin. There is an underlying genetic predisposition to the development of DH, but environmental factors are also important. This paper describes these different factors and discusses the known mechanism that lead to the development of skin lesions.

    Full Text Available pyoderma gangrenosum is a rare inflammatory skin condition characterized by progressive and recurrent skin ulceration of destructive course. It is usually associated with rheumatoid arthritis, paraproteinemia, myeloproliferative diseases and inflammatory bowel diseases, especially non-specific ulcerative proctocolitis. In these situations, skin lesions are described as concurrent with the intestinal condition. However, reports on pyoderma gangrenosum preceding intestinal findings are less frequent. The authors describe a case of a woman with febrile condition associated with skin lesions diagnosed by biopsy as pyoderma gangrenosum. Two weeks later, she developed diarrhea, arthralgia and sepsis, being diagnosed as ulcerative proctocolitis. After the administration of the treatment for ulcerative proctocolitis, she showed improvements in sepsis care, remission of diarrhea and regression of skin lesions. This case highlights the importance of considering pyoderma gangrenosum as a manifestation associated with inflammatory bowel disease, regardless of its timing in relation to intestinal symptoms.Pioderma gangrenoso é uma forma de inflamação cutânea, caracterizada por ulceração progressiva e recorrente da pele, com curso destrutivo.

    Diabetes mellitus and the prediabetic state are associated with a number of skin manifestations. This study is a systematic review of the following manifestations: acanthosis nigricans (AN), skin tags (ST), diabetic dermopathy (DD), rubeosis faciei (RF), pruritus (PR), granuloma annulare (GA), necrobiosis lipoidica (NL), scleroedema diabeticorum (SD) and bullosis diabeticorum (BD). These conditions possibly relate to underlying diabetogenic mechanisms. Our aim was to determine whether skin signs are feasible as cutaneous markers for the prediabetic or diabetic state. Data were collected from the databases PubMed, Embase and Cochrane. Articles were excluded if the populations presented with comorbidities or received treatment with drugs affecting the skin. Also, animal studies, studies with poor methodology and pilot studies were excluded. Among the 34 included original articles, an association with diabetes was shown as follows: in eight articles with AN, five articles with ST, three articles with GA, two articles with NL, PR and SD respectively and in one article with RF. Three papers indirectly showed an association of DD with diabetes. Association between bullous skin lesions and diabetes was only documented by case reports and case series. The results indicate a benefit of diabetes screening in individuals presenting with AN, ST or BD. Further studies are required to enlighten a possible association with RF, GA, SD or NL. Until such studies are available, it is advisable to screen individuals with the skin lesions presented by measuring their glycated haemoglobin.

  15. Skin Examination: An Important Diagnostic Tool in Renal Failure Patients.

    2018-01-01

    Renal failure is common in the United States with an estimated prevalence of 660,000 treated end-stage renal disease patients in 2015 [1]. Causes of renal failure are many, and complications from renal failure, underlying disease, and treatment are not infrequent. Examples of common skin manifestations include xerosis, pigmentary change, and nail dystrophies. Frequent disease-specific skin changes may be helpful in the diagnosis of primary disorders leading to renal disease or severity of disease including bullosis diabeticorum, sclerodactyly, or leukoctoclastic vasculitis. Some cutaneous changes, such as the multiple angiokeratomas of Fabry disease or the plexiform neurofibromas of neurofibromatosis, are pathognomonic of genetic disorders, which often lead to renal failure. Careful examination of the skin can provide crucial clues to diagnosis of renal failure causation and aid in monitoring complications. © 2018 S. Karger AG, Basel.

  16. Immune Modulation of Cardiac Repair and Regeneration: The Art of Mending Broken Hearts.

    Zlatanova, Ivana; Pinto, Cristina; Silvestre, Jean-Sébastien

    2016-01-01

    The accumulation of immune cells is among the earliest responses that manifest in the cardiac tissue after injury. Both innate and adaptive immunity coordinate distinct and mutually non-exclusive events governing cardiac repair, including elimination of the cellular debris, compensatory growth of the remaining cardiac tissue, activation of resident or circulating precursor cells, quantitative and qualitative modifications of the vascular network, and formation of a fibrotic scar. The present review summarizes the mounting evidence suggesting that the inflammatory response also guides the regenerative process following cardiac damage. In particular, recent literature has reinforced the central role of monocytes/macrophages in poising the refreshment of cardiomyocytes in myocardial infarction- or apical resection-induced cardiac insult. Macrophages dictate cardiac myocyte renewal through stimulation of preexisting cardiomyocyte proliferation and/or neovascularization. Nevertheless, substantial efforts are required to identify the nature of these macrophage-derived factors as well as the molecular mechanisms engendered by the distinct subsets of macrophages pertaining in the cardiac tissue. Among the growing inflammatory intermediaries that have been recognized as essential player in heart regeneration, we will focus on the role of interleukin (IL)-6 and IL-13. Finally, it is likely that within the mayhem of the injured cardiac tissue, additional types of inflammatory cells, such as neutrophils, will enter the dance to ignite and refresh the broken heart. However, the protective and detrimental inflammatory pathways have been mainly deciphered in animal models. Future research should be focused on understanding the cellular effectors and molecular signals regulating inflammation in human heart to pave the way for the development of factual therapies targeting the inflammatory compartment in cardiac diseases.

    Tuberous sclerosis complex (TSC) is an autosomal dominant disorder characterized by the development of benign hamartomas in multiple organs. Most patients with TSC exhibit cutaneous manifestations. We report a 28-year-old patient with multiple pink papules at the proximal nail fold of several toes. Histopathological analysis of a biopsy of a papule was consistent with an ungual fibroma. Histopathological analysis of a biopsy of an elevated skin-colored plaque at the lower back was diagnostic for a Shagreen patch. These findings were consistent with a clinical diagnosis of TSC. This patient was subsequently referred to a multidisciplinary TSC clinic for further screening, which revealed a giant cell astrocytoma and multiple subependymal tubers. Annual monitoring was recommended. The skin lesions were treated with topical rapamycin ointment. Recognizing dermatological manifestations of TSC is of importance to allow early diagnosis. TSC should be considered as a differential diagnosis in the case of ungual fibromas, even in older patients.

    Full Text Available Background: Tuberous sclerosis complex (TSC is an autosomal dominant disorder characterized by the development of benign hamartomas in multiple organs. Most patients with TSC exhibit cutaneous manifestations. Methods: We report a 28-year-old patient with multiple pink papules at the proximal nail fold of several toes. Results: Histopathological analysis of a biopsy of a papule was consistent with an ungual fibroma. Histopathological analysis of a biopsy of an elevated skin-colored plaque at the lower back was diagnostic for a Shagreen patch. These findings were consistent with a clinical diagnosis of TSC. This patient was subsequently referred to a multidisciplinary TSC clinic for further screening, which revealed a giant cell astrocytoma and multiple subependymal tubers. Annual monitoring was recommended. The skin lesions were treated with topical rapamycin ointment. Conclusions: Recognizing dermatological manifestations of TSC is of importance to allow early diagnosis. TSC should be considered as a differential diagnosis in the case of ungual fibromas, even in older patients.

    Full Text Available Crohn’s disease (CD is an inflammatory disorder of the gastrointestinal tract that is likely caused by an inappropriate mucosal inflammatory response to intestinal bacteria in a genetically predisposed host. The lesions of CD can involve any region of the GI tract as well as extraintestinal sites such as the skin, joints, and eyes. The most common presenting symptoms are abdominal pain and prolonged diarrhea associated with fevers, fatigue, and malaise. Delayed growth and failure to thrive may also be observed in pediatric patients. Oral manifestations of CD are known as oral CD and may precede GI involvement, thus serving as early markers of this condition. We describe a 6-year-old male who presented with oral lesions as his initial manifestation of disease and review the current literature pertaining to oral CD.

    Sudden cardiac death is defined as death from unexpected circulatory arrest-usually a result of cardiac arrhythmia-that occurs within 1 hour of the onset of symptoms. Proper and timely identification of individuals at risk for sudden cardiac death and the diagnosis of its predisposing conditions are vital. A careful history and physical examination, in addition to electrocardiography and cardiac imaging, are essential to identify conditions associated with sudden cardiac death. Among young adults (18-35 years), sudden cardiac death most commonly results from a previously undiagnosed congenital or hereditary condition, such as coronary artery anomalies and inherited cardiomyopathies (eg, hypertrophic cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy [ARVC], dilated cardiomyopathy, and noncompaction cardiomyopathy). Overall, the most common causes of sudden cardiac death in young adults are, in descending order of frequency, hypertrophic cardiomyopathy, coronary artery anomalies with an interarterial or intramural course, and ARVC. Often, sudden cardiac death is precipitated by ventricular tachycardia or fibrillation and may be prevented with an implantable cardioverter defibrillator (ICD). Risk stratification to determine the need for an ICD is challenging and involves imaging, particularly echocardiography and cardiac magnetic resonance (MR) imaging. Coronary artery anomalies, a diverse group of congenital disorders with a variable manifestation, may be depicted at coronary computed tomographic angiography or MR angiography. A thorough understanding of clinical risk stratification, imaging features, and complementary diagnostic tools for the evaluation of cardiac disorders that may lead to sudden cardiac death is essential to effectively use imaging to guide diagnosis and therapy.

    Full Text Available Abstract Introduction Chronic lymphocytic leukemia is an indolent disease that often presents with complaints of lymphadenopathy or is detected as an incidental laboratory finding. It is rarely considered in the differential diagnosis of patients presenting with tamponade or a large, bloody pericardial effusion. In patients without known cancer, a large, bloody pericardial effusion raises the possibility of tuberculosis, particularly in patients from endemic areas. However, the signs, symptoms and laboratory findings of pericarditis related to chronic lymphocytic leukemia can mimic tuberculosis. Case Presentation We report the case of a 58-year-old African American-Nigerian woman with a history of travel to Nigeria and a positive tuberculin skin test who presented with cardiac tamponade. She had a mild fever, lymphocytosis and a bloody pericardial effusion, but cultures and stains were negative for acid-fast bacteria. Assessment of blood by flow cytometry and pericardial biopsy by immunohistochemistry revealed CD5 (+ and CD20 (+ lymphocytes in both tissues, demonstrating this to be an unusual manifestation of early stage chronic lymphocytic leukemia. Conclusion Although most malignancies that involve the pericardium clinically manifest elsewhere before presenting with tamponade, this case illustrates the potential for early stage chronic lymphocytic leukemia to present as a large pericardial effusion with tamponade. Moreover, the presentation mimicked tuberculosis. This case also demonstrates that it is possible to treat chronic lymphocytic leukemia-related pericardial tamponade by removal of the fluid without chemotherapy.

    Manifestations of cocaine poisoning range widely from mild sympathomimetic overdrive to life-threatening seizures, hyperthermia, and cardiac dysrhythmias. While supportive care, including the judicious use of benzodiazepines and cooling measures, is paramount, the management of cocaine-associated wide-complex dysrhythmias and cardiac arrest regularly includes sodium bicarbonate boluses in order to narrow QRS length. When confronted with refractory dysrhythmias, one must weigh the benefits and...

    Full Text Available Venomous animals are those that, by means of a hunting and defense mechanism, are able to inject their prey with a toxic substance produced in their bodies, directly from specialized glands (e.g., tooth, sting, spur through which the poison passes. Millipedes are poisonous animals; they can be harmful to humans, and their effects usually manifest as erythematous, purpuric, and cyanotic lesions; local pain; and paresthesia. Here, we report a case of skin contact with a millipede for 6h resulting in skin lesions similar to blue toe syndrome.

    Selective lymphoid irradiation (SLI) using palladium-109-hematoporphyrin (Pd-H), given four days prior to transplantation, combined with two doses of antilymphocyte globulin (ALG) (10 mg, days -2 and -1), was evaluated as a method of induction of permanent heterotopic cardiac allograft survival in the highly histoincompatible rat strain combination of ACI (RT1(1))-to-Lewis (RT1a). Both Pd-H and ALG localize poorly in the thymus, so this study evaluated whether thymic irradiation (TI) or thymectomy (TX) of the adult recipient results in indefinite allograft survival. Immunosuppression with Pd-H or ALG alone gave a mean survival time (MST) of 6.7 +/- 0.6 days, but the combination of the two agents led to an MST of 17.6 +/- 3.4 days. When TI was combined with Pd-H and ALG, cardiac allograft survival was prolonged to 50.2 +/- 13.9 days, but TI alone showed an MST of 10.3 +/- 1.8 days. Permanent cardiac allograft survival (greater than 250 days) was achieved in all thymectomized recipients treated with the combination of Pd-H and a brief course of ALG. These animals also accepted second-set skin grafts and rejected third-party skin grafts following more than 150 days of ACI cardiac allograft survival. Thymic irradiation, although effective in acting synergistically with SLI and ALG, led to prolonged, but limited allograft survival, although thymectomy with SLI and ALG is synergistic in prolonging allograft survival permanently without chronic immunosuppression

  9. Hypopigmented mycosis fungoides in a twenty-year-old Saudi woman with fair skin

    2006-01-01

    Full Text Available The hypopigmented variant of mycosis fungoides (MF is charactrized by the presence of hypopigmented patches as the sole manifestation of the disease. This variant is usually observed in the dark skin of African or Asian individuals particularly children, but nevertheless is an uncommonly reported presentation of the disease. The incidence of hypopigmented MF in Caucasian patients and others of fair skin color is rare. We describe hypopigmented lesions arising in a twenty-year-old Saudi woman with type IV skin color. The diagnosis of mycosis fungoides stage IA was made based on the clinico-radiological and histological features. The patient responded well to PUVA therapy and is currently clear of lesions. MF should be considered in the differential diagnosis of hypopigmented macular lesions in patients of any skin color and age. Multiple skin biopsies must be performed on different occasions so as not to miss the diagnosis; and long term follow up is recommended since recurrence is common and occasional cases behave aggressively.

    2016-01-01

    Abstract Cardiac cachexia (CC) is the clinical entity at the end of the chronic natural course of heart failure (HF). Despite the efforts, even the most recent definition of cardiac cachexia has been challenged, more precisely, the addition of new criteria on top of obligatory weight loss. The pathophysiology of CC is complex and multifactorial. A better understanding of pathophysiological pathways in body wasting will contribute to establish potentially novel treatment strategies. The complex biochemical network related with CC and HF pathophysiology underlines that a single biomarker cannot reflect all of the features of the disease. Biomarkers that could pick up the changes in body composition before they convey into clinical manifestations of CC would be of great importance. The development of preventive and therapeutic strategies against cachexia, sarcopenia, and wasting disorders is perceived as an urgent need by healthcare professionals. The treatment of body wasting remains an unresolved challenge to this day. As CC is a multifactorial disorder, it is unlikely that any single agent will be completely effective in treating this condition. Among all investigated therapeutic strategies, aerobic exercise training in HF patients is the most proved to counteract skeletal muscle wasting and is recommended by treatment guidelines for HF.

    Full Text Available Manifestation of chorea in patients with systemic lupus erythematosus (SLE and antiphospholipid antibody syndrome (APA synd. is not common. Moreover, primary presentation of the disease with chorea is rare and only few such cases are reported in literature in recent years. We report here the case of a 28 year old woman who was first seen at the age of 10 with clinical manifestations of chorea. Later she developed deep vein thrombosis, thrombocytpenia, stroke, cardiac valve involvement and recurrent abortions. Laboratory investigations confirmed the diagnosis of SLE and the presence of antiphospholipid antibodies. We present this patient as a case of SLE and antiphospholipid antibody syndrome with chorea being her primary clinical presentation

    Human skin is the largest organ of the body accounting for approximately 16% of the total bodyweight. Skin is readily exposed to ionizing radiation during either accidental or intentional exposure such as radiotherapy or other medical procedures because it constitutes the interface between environment and internal organs. Estimation of accurate entrance skin dose and maximum absorbed dose (MAD) is crucial to prevent serious skin injuries. Cutaneous Radiation Syndrome (CRS) is defined by a number of pathological changes manifested in the skin and severity of these changes depend on Liner Energy Transfer (LET), dose, dose-rate, geometry of exposure and volume of body part exposed. In most of the radiological accident scenarios, reconstructive dosimetry in the skin has been performed using physical (thermoluminescence and optical stimulated luminescence), biological (cytogenetics) and computational methods/models to manage radiation exposed victims.Results of the cytogenetic testing performed at the CBL on a few patients will be discussed to illustrate the potential use of DCA and other cytogenetic techniques such as micronuclei and multicolor FISH in monitoring the health of radiotherapy patients

    Pituitary tumor apoplexy is a rare clinical syndrome caused by acute hemorrhage or infarction in a preexisting pituitary adenoma. It typically manifests as an acute episode of headache, visual disturbance, mental status changes, cranial nerve palsy, and endocrine pituitary dysfunction. However, not all patients present with classical symptoms, so it is pertinent to appreciate the clinical spectrum of pituitary tumor apoplexy presentation. We report an unusual case of a patient with pituitary tumor apoplexy who presented with periorbital edema associated with hypopituitarism. An 83-year-old Japanese man developed acute anterior hypopituitarism; he showed anorexia, fatigue, lethargy, severe bilateral periorbital edema, and mild cardiac dysfunction in the absence of headache, visual disturbance, altered mental status, and cranial nerve palsy. Magnetic resonance imaging showed a 2.5-cm pituitary tumor containing a mixed pattern of solid and liquid components indicating pituitary tumor apoplexy due to hemorrhage in a preexisting pituitary adenoma. Replacement therapy with oral hydrocortisone and levothyroxine relieved his symptoms of central adrenal insufficiency, central hypothyroidism, periorbital edema, and cardiac dysfunction. Common causes of periorbital edema include infections, inflammation, trauma, allergy, kidney or cardiac dysfunction, and endocrine disorders such as primary hypothyroidism. In the present case, the patient's acute central hypothyroidism was probably involved in the development of both periorbital edema and cardiac dysfunction. The present case highlights the need for physicians to consider periorbital edema as an unusual predominant manifestation of pituitary tumor apoplexy.

    Full Text Available Background: As the goal of endoscopic conduit harvesting is to decrease pain and better cosmetic appearance, and as the optimal choice of skin closure after endoscopic radial artery harvesting (ERAH has not yet been determined, we started this study with an aim to compare wound complications, patient satisfaction and scar healing between glue (Dermabond versus polyglactin intra-cuticular suture for skin closure after ERAH. Methods: This observational study was done at Al Dabbous Cardiac Center, Kuwait, from January 2017 till October 2017 enrolling 40 patients divided into two equal groups (Dermabond group and sutures group. Inclusion criterion was patients underwent coronary artery bypass grafting (CABG using ERAH, while open technique for radial artery harvesting and Negro race are considered as exclusion criteria. Demographic data were collected, (gender, age, race, body mass index (BMI, preoperative medication and albumin level, as well as diabetes or peripheral vascular disease. Operatively, wound closure time was calculated for all patients. Postoperatively: Cosmetic appearance was assessed using the Hollander scale. Patient satisfaction was recorded at week 6–8 weeks. Results: Demographic and preoperative data were comparable; Dermabond group showed shorter closure time, better scar pigmentation, shape and patient satisfaction. Pain, scar size, infection and hematoma showed no statistical difference. Conclusion: Dermabond can be used safely in closure of skin after ERAH. The excellent results in the small wound of ERAH encouraged us to use it in larger wounds. Keywords: Dermabond, Wound, ERAH, Skin adhesive, OCA

    Full Text Available Background: Polycystic ovarian syndrome (PCOS is a heterogenous collection of signs and symptoms that when gathered, form a spectrum of disorder with disturbance of reproductive, endocrine and metabolic functions. Aim: The aim of this study is to correlate the skin manifestations with hormonal changes and to know the incidence and prevalence of skin manifestations in patients with PCOS. Materials and Methods: A total of 40 patients with PCOS were examined during 1 year time period from May 2008 P to May 2009. Detailed clinical history was taken from each patient. PCOS was diagnosed on the basis of ultrasonography. Hormonal assays included fasting blood sugar, postprandial blood sugar, follicle-stimulating hormone, luteinizing hormone, thyroid stimulating hormone, dehydroepiandrostenedione, prolactin, free testosterone, fasting lipid profile and sex hormone binding globulin. The results obtained were statistically correlated. Results: In our study, the prevalence of cutaneous manifestations was 90%. Of all the cutaneous manifestations acne was seen in highest percentage (67.5%, followed by hirsutism (62.5%, seborrhea (52.5%, androgenetic alopecia (AGA (30%, acanthosis nigricans (22.5% and acrochordons (10%. Fasting insulin levels was the most common hormonal abnormality seen in both acne and hirsutism, whereas AGA was associated with high testosterone levels. Conclusion: The prevalence of cutaneous manifestations in PCOS was 90%. Hirsutism, acne, seborrhea, acanthosis nigricans and acrochordons were associated with increased levels of fasting insulin, whereas AGA showed higher levels of serum testosterone.

    The term barrier function as applied to human skin often connotes the physical properties of this organ that provide protection from its surrounding environment. This term does not generally include skin pigmentation. However, skin pigmentation, which is the result of melanin produced in melanocytes residing the basal layer of the skin and exported to the keratinocytes in the upper layers, serves equally important protective function. Indeed, changes in skin pigmentation are often the most readily recognized indicators of exposure of skin to damaging agents, especially to natural and artificial radiation in the environment. Several recent studies have shed new light on a) the mechanisms of involved in selective effects of subcomponents of UV radiation on human skin pigmentation and b) the interactive influences between keratinocytes and melanocytes, acting as ‘epidermal melanin unit’, that manifest as changes in skin pigmentation in response to exposure to various forms of radiation. This article provides a concise review of our current understanding of the effects of the non-ionizing solar radiation, at cellular and molecular levels, on human skin pigmentation. PMID:22404235

    It is the uniqueness of Virtual Reality as a medium that calls for the creation of hybrid realities which blur the finite boundaries between physical and digital existence. Virtual Reality's distinguishing features as an artistic medium embody a distinct form of aesthetics: it is a stereoscopic, immersive, interactive, performative, dynamic, and experiential medium. A Virtual Reality art piece manifests in multiple ways. It can present itself as an interactive virtual archetype, exploring concepts rendered from different perspectives, and as an impetus to challenge the platform's capabilities, not only theoretically as an artistic practice, but also by calling for the instantiation of authoring tools for the development of virtual reality experiences. The paradigm presented in this paper is a Virtual Reality art piece, called skin, 2006, developed on Electro, which is an open-source cross-platform development environment. skin, 2006, is an interactive hypersteroscopic high-definition audiovisual installation that explores a dialogue between physical and digital senses of "touch".

    Marfan syndrome (MFS) is a systemic disorder of connective tissue caused by mutations in fibrillin-1. Cardiac dysfunction in MFS has not been characterized halting the development of therapies of cardiac complication in MFS. We aimed to study the age-dependent cardiac remodeling in the mouse model of MFS FbnC1039G+/- mouse [Marfan heterozygous (HT) mouse] and its association with valvular regurgitation. Marfan HT mice of 2-4 mo demonstrated a mild hypertrophic cardiac remodeling with predominant decline of diastolic function and increased transforming growth factor-β canonical (p-SMAD2/3) and noncanonical (p-ERK1/2 and p-p38 MAPK) signaling and upregulation of hypertrophic markers natriuretic peptides atrium natriuretic peptide and brain natriuretic peptide. Among older HT mice (6-14 mo), cardiac remodeling was associated with two distinct phenotypes, manifesting either dilated or constricted left ventricular chamber. Dilatation of left ventricular chamber was accompanied by biochemical evidence of greater mechanical stress, including elevated ERK1/2 and p38 MAPK phosphorylation and higher brain natriuretic peptide expression. The aortic valve regurgitation was registered in 20% of the constricted group and 60% of the dilated group, whereas mitral insufficiency was observed in 40% of the constricted group and 100% of the dilated group. Cardiac dysfunction was not associated with the increase of interstitial fibrosis and nonmyocyte proliferation. In the mouse model fibrillin-1, haploinsufficiency results in the early onset of nonfibrotic hypertrophic cardiac remodeling and dysfunction, independently from valvular abnormalities. MFS heart is vulnerable to stress-induced cardiac dilatation in the face of valvular regurgitation, and stress-activated MAPK signals represent a potential target for cardiac management in MFS.

  2. What do we know about the cardiac valve lesion in the antiphospholipid syndrome (APS)?

    Amigo, M-C

    2014-10-01

    Heart valve disease (HVD) is the most common cardiac manifestation in the antiphospholipid syndrome (APS). Valve lesions should be described according to the established definition. HVD is progressive despite anticoagulant/antiplatelet treatments. Around 4-6% of patients with HVD in APS will require valve replacement surgery, which is considered a very high risk procedure in APS. Unfortunately, no recommendations regarding medical treatment of antiphospholipid antibodies-associated HVD can be made at this moment. There are evidence-based data and strong pathophysiologic rationale for considering HVD as a manifestation of APS. Thus, HVD should be included as a criterion of definite APS. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

  4. Generalized subcutaneous edema as a rare manifestation of dermatomyositis: clinical lesson from a rare feature.

    LENUS (Irish Health Repository)

    Haroon, Muhammad

    2011-04-01

    Generalized subcutaneous edema is a very rare manifestation of inflammatory myopathies. A 61-year-old woman presented with classic signs and symptoms of dermatomyositis. She was also noted to have generalized edema that was so florid that an alternative diagnosis was considered. Her disease was resistant to corticosteroids, azathioprine, and mycophenolate mofetil. Intravenous administration of immunoglobulins was started because of marked worsening of her disease-muscle weakness, generalized anasarca, and involvement of her bulbar muscles. This led to dramatic resolution of her subcutaneous edema and significant improvement of her skin and muscle disease. As the initial screen for malignancy was negative, a positron emission tomography-computed tomography scan was requested, which interestingly showed a metabolically active cervical tumor. Anasarca is an unusual manifestation of dermatomyositis. In treatment-refractory cases, it seems reasonable to consider positron emission tomography scan in excluding underlying malignant disease.

  5. Measuring the effects of topically applied skin optical clearing agents and modeling the effects and consequences for laser therapies

    Human skin prepared with an optical clearing agent manifests reduced scattering as a result of de-hydration and refractive index matching. This has potentially large effects for laser therapies of several skin lesions such as port wine stain, hair removal and tattoo removal. With most topically applied clearing agents the clearing effect is limited because they penetrate poorly through the intact superficial skin layer (stratum corneum). Agent application modi other than topical are impractical and have limited the success of optical clearing in laser dermatology. In recent reports, however, a mixture of lipofylic and hydrofylic agents was shown to successfully penetrate through the intact stratum corneum layer which has raised new interest in this field. Immediately after application, the optical clearing effect is superficial and, as the agent diffuses through the skin, reduced scattering is manifested in deeper skin layers. For practical purposes as well as to maximize therapeutic success, it is important to quantify the reduced scattering as well as the trans-cutaneous transport dynamics of the agent. We determined the time and tissue depth resolved effects of optically cleared skin by inserting a microscopic reflector array in the skin. Depth dependent light intensity was measured by quantifying the signal of the reflector array with optical coherence tomography. A 1-dimensional mass diffusion model was used to estimate a trans-cutaneous transport diffusion constant for the clearing agent mixture. The results are used in Monte Carlo modeling to determine the optimal time of laser treatment after topical application of the optical clearing agent.

    Skin toxicity is a frequent complication of anti-epidermal growth factor receptor therapy, which can be an obstacle in maintaining the dose intensity and may negatively impact on the clinical outcome of cancer patients. Skin lesions depend on the disruption of the keratinocyte development pathways and no treatment is clearly effective in resolving the cutaneous alterations frequently found during anti-epidermal growth factor receptor therapy. Among systemic treatments, oral tetracycline proved to be useful in preventing skin manifestations. We describe the case of a patient affected by metastatic colorectal cancer, for whom a combination of chemotherapy and cetuximab was used as second-line treatment. The patient developed a symptomatic papulopustular skin rash that disappeared completely after a twice-daily application of a hydrating and moisturizing cream, mainly consisting of a mixture of paraffin, silicone compounds, and macrogol. The marked cutaneous amelioration allowed the patient to continue cetuximab without any further symptoms and was associated with a partial radiological response.

    Full Text Available Abstract Introduction Cardiac tamponade is a rare manifestation of hypothyroidism, and a less rare cause of pericardial effusion. The accumulation of the pericardial fluid is gradual, and often does not compromise cardiac hemodynamic function. There is a relationship between the severity and chronicity of the disease with the presence of pericardial effusion. There are few cases describing associated pericardial tamponade published in the literature. When a tamponade occurs, a concomitant provocative factor such as a viral pericarditis may be related. Our patient's case appears to be the youngest patient described so far. Case presentation We report the case of a previously healthy five-year-old Hispanic (non-indigenous boy who developed rhabdomyolysis with a history of a recent pericardial effusion and tamponade two months before that required the placement of a percutaneous pericardial drainage. Pericardial effusion was considered to be viral. Later on readmission, clinical primary hypothyroidism was diagnosed and thought to be associated with the previous cardiac tamponade. He developed rhabdomyolysis, which was considered to be autoimmune and was treated with steroids. The level of creatine phosphate kinase and creatine kinase MB fraction returned to within the reference rangeone week after our patient was started on steroids and three weeks after he was started on thyroid hormones. Conclusions Physicians should consider hypothyroidism as a differential diagnosis in patients with pericardial effusion. Pericardial effusion may progress and cause a cardiac tamponade with hemodynamic instability. The fact that our patient did not have any manifestations of hypothyroidism might have delayed diagnosis.

    Full Text Available Several genetic disorders caused by defective nucleotide excision repair that affect the skin and the nervous system have been described, including Xeroderma Pigmentosum (XP, De Sanctis–Cacchione syndrome (DSC, Cockayne syndrome, and Trichothiodystrophy. Cutaneous photosensitivity with an increased risk of skin malignancy is a common feature of these disorders, but clinical manifestations commonly overlap these syndromes. Several genes have been found to be altered in these pathologies, but we lack more genotype-phenotype correlations in order to make an accurate diagnosis. Very few cases of DSC syndrome have been reported in the literature. We present a case of a 12-year-old Colombian male, with multiple skin lesions in sun-exposed areas from the age of 3 months and a history of 15 skin cancers. He also displayed severe neurologic abnormalities (intellectual disability, ataxia, altered speech, and hyperreflexia, short stature, and microcephaly, which are features associated with DSC. Genetic testing revealed a novel germline mutation in the XP-C gene (c.547A>T. This is the first case of an XP-C mutation causing De Sanctis–Cacchione syndrome. Multigene panel testing is becoming more widely available and accessible in the clinical setting and will help rapidly unveil the molecular etiology of these rare genetic disorders.

    Full Text Available Introduction: Scleroderma (systemic sclerosis [SSc] is a rare autoimmune disease which manifests as fibrosis in the skin and other internal organs. Conventionally, the modified Rodnan skin score (MRSS has been used to quantify the extent of skin fibrosis (resulting in skin tightness in SSc. This technique, although widely validated, is limited by the requirement of a trained, experienced assessor. Recent literature suggests that utilization of the objective ultrasound-based assessment of skin fibrosis utilizing shear wave elastography (SWE may be a more robust technique to detect early skin tightness in SSc. Methods: We evaluated the use of SWE (assessed by an experienced radiologist in 24 patients with SSc compared with 16 healthy controls. Results: Our patients were predominantly females, with median disease duration of 1.5 years and median MRSS of 17. There was minimal intraobserver variation in the assessment of SWE. Patients with SSc had higher SWE values (mean elasticity [Emean] compared to healthy controls at most assessed sites for the MRSS. The Emeancorrelated significantly at all sites with the MRSS scores. At the sites where MRSS was scored as 0 (normal, the Emeanin patients with SSc was higher when compared with similarly clinical normal skin in patients with SSc, suggesting potential early involvement of these areas of the skin with fibrosis. Conclusion: SWE is a promising tool to objectively assess skin fibrosis in SSc and may be useful in detecting early, subclinical skin involvement in this disease.

    Currently, there is a limited ability to interactively study developmental cardiac mechanics and physiology. We therefore combined light-sheet fluorescence microscopy (LSFM) with virtual reality (VR) to provide a hybrid platform for 3D architecture and time-dependent cardiac contractile function characterization. By taking advantage of the rapid acquisition, high axial resolution, low phototoxicity, and high fidelity in 3D and 4D (3D spatial + 1D time or spectra), this VR-LSFM hybrid methodology enables interactive visualization and quantification otherwise not available by conventional methods, such as routine optical microscopes. We hereby demonstrate multiscale applicability of VR-LSFM to (a) interrogate skin fibroblasts interacting with a hyaluronic acid-based hydrogel, (b) navigate through the endocardial trabecular network during zebrafish development, and (c) localize gene therapy-mediated potassium channel expression in adult murine hearts. We further combined our batch intensity normalized segmentation algorithm with deformable image registration to interface a VR environment with imaging computation for the analysis of cardiac contraction. Thus, the VR-LSFM hybrid platform demonstrates an efficient and robust framework for creating a user-directed microenvironment in which we uncovered developmental cardiac mechanics and physiology with high spatiotemporal resolution.

    Objective: To investigate the dynamic expression of apoptosis-related genes Bcl-2, Bax and P53 in acute radiation-induced skin ulcers, and to explore the underlying mechanism involved in retarded healing of the ulcer. Methods: Fifty-four female SD rats were divided into 3 groups. The model of acute radiation-induced skin injury, in rats was replicated with 45 Gy electron accelerator β-ray to the skin as radiation group (n=24); the model of deep second degree scald in rats was established as burn group (n=24); 6 normal rats were served as normal control group. From different periods skin wounds, the expression of Bcl-2, Bax and P53 were respectively assessed by means of immunohistochemical technique and. apoptosis was observed by TUNEL assay. Results: (1) The result of the TUNEL manifested that the integral absorbance (IA) of the radiation group was much higher than that of the control group. There is statistical significance between the two groups (P<0.05). (2) 0, 1, 2, 3 weeks after wound emerging, the Bax and P53 integral absorbance (IA) in radiation group was much higher than that of the control group. The Bcl-2 integral absorbance (IA) in bum group was much higher than that of the radiation group. There is statistical significance between the two groups (P<0.05). Conclusions: It was shown that apoptosis of β radiation manifested three typical characteristics, namely early occurrence, high frequency and delayed disappearance after radiation, which might explain the delayed wound healing caused by β radiation.

    Without heart transplantation, a large number of patients with failing hearts worldwide face poor outcomes. By means of cardiomyocyte regeneration, cardiac regeneration therapy is emerging with great promise as a means for restoring loss of cardiac function. However, the limited success of clinical trials using bone marrow-derived cells and myoblasts with heterogeneous constituents, transplanted at a wide range of cell doses, has led to disagreement on the efficacy of cell therapy. It is therefore essential to reevaluate the evidence for the efficacy of cell-based cardiac regeneration therapy, focusing on targets, materials, and methodologies. Meanwhile, the revolutionary innovation of cardiac regeneration therapy is sorely needed to help the millions of people who suffer heart failure from acquired loss of cardiomyocytes. Cardiac regeneration has been used only in limited species or as a developing process in the rodent heart; now, the possibility of cardiomyocyte turnover in the human heart is being revisited. In the pursuit of this concept, the use of cardiac stem/progenitor stem cells in the cardiac niche must be focused to usher in a second era of cardiac regeneration therapy for the severely injured heart. In addition, tissue engineering and cellular reprogramming will advance the next era of treatment that will enable current cell-based therapy to progress to "real" cardiac regeneration therapy. Although many barriers remain, the prevention of refractory heart failure through cardiac regeneration is now becoming a realistic possibility.

    Talys J. Pinheiro

    Full Text Available ABSTRACT The epidemics of Chikungunya virus (CHIKV and Zika virus (ZIKV infections have been considered the most important epidemiological occurrences in the Americas. The clinical picture of CHIKV infection is characterized by high fever, exanthema, myalgia, headaches, and arthralgia. Besides the typical clinical picture of CHIKV, atypical manifestations of neurological complications have been reported: meningo-encephalitis, meningoencephalo-myeloradiculitis, myeloradiculitis, myelitis, myeloneuropathy, Guillain-Barré syndrome and others. The diagnosis is based on clinical, epidemiological, and laboratory criteria. The most common symptoms of ZIKV infection are skin rash (mostly maculopapular, fever, arthralgia, myalgia, headache, and conjunctivitis. Some epidemics that have recently occurred in French Polynesia and Brazil, reported the most severe conditions, with involvement of the nervous system (Guillain-Barré syndrome, transverse myelitis, microcephaly and meningitis. The treatment for ZIKV and CHIKV infections are symptomatic and the management for neurological complications depends on the type of affliction. Intravenous immunoglobulin, plasmapheresis, and corticosteroid pulse therapy are options.

    Full Text Available Erdheim-Chester Disease is a rare form of multiorgan non-Langerhans’ cell histiocytosis that affects individuals between the ages of 50 and 70 with an equal distribution among males and females. It is associated with significant morbidity and mortality that is mostly due to infiltration of critical organs. Some of the sites that Erdheim-Chester Disease affects include the skeletal system, central nervous system, cardiovascular system, lungs, kidneys (retroperitoneum, and skin. The most common presenting symptom of Erdheim-Chester Disease is bone pain although a large majority of patients are diagnosed incidentally during a workup for a different disease process. Diagnosing Erdheim-Chester Disease is challenging due its rarity and mimicry to other infiltrative processes. Therefore, a multimodality diagnostic approach is employed with imaging being at the forefront. As of date, a comprehensive radiologic review of the manifestations of Erdheim-Chester Disease has rarely been reported. Here we present radiologic findings of an individual suffering from Erdheim-Chester Disease.

    The dynamics of fingertip contact manifest themselves in the complex skin movements observed during the transition from a stuck state to a fully developed slip. While investigating this transition, we found that it depended on skin hydration. To quantify this dependency, we asked subjects to slide their index fingertip on a glass surface while keeping the normal component of the interaction force constant with the help of visual feedback. Skin deformation inside the contact region was imaged with an optical apparatus that allowed us to quantify the relative sizes of the slipping and sticking regions. The ratio of the stuck skin area to the total contact area decreased linearly from 1 to 0 when the tangential force component increased from 0 to a maximum. The slope of this relationship was inversely correlated to the normal force component. The skin hydration level dramatically affected the dynamics of the contact encapsulated in the course of evolution from sticking to slipping. The specific effect was to reduce the tendency of a contact to slip, regardless of the variations of the coefficient of friction. Since grips were more unstable under dry skin conditions, our results suggest that the nervous system responds to dry skin by exaggerated grip forces that cannot be simply explained by a change in the coefficient of friction.

    We discuss the cardiac {sup 123}I-MIBG ({sup 123}I-metaiodobenzylguanidine) scintigraphy in patients with Parkinson`s disease (PD) based on our results, and examine the clinical significance in lowering MIBG storage. Thirty-four patients with PD without diabetes millitus or heart failure, presenting normal cardiac thallium scintigraphy, were examined. They included 13 male and 21 female, aged from 52 to 83 (average age 70.1) and their morbid period was between 0.25 and 19 years (agerage 4.9 years). Ten patients with age-matched disease control were chosen. They contained 5 male and 5 female, aged from 59 to 77 (average age 70.7), suffering from headache, vertigo, cerebral infarction, etc. PD patients group and the age-matched control group were compared with the normal control group. In PD patients, MIBG storage was significantly lowered on the initial and the late images in comparison with the disease and neurological control groups, and the wash-out rate was enhanced. There was negative correlation or the expected tendency of correlation between MIBG storage and the clinical severity. MIBG storage was lowered with longer morbid period. Anti-Parkinson drugs had no apparent effects on MIBG storage. The detection rate of abnormality by cardiac MIBG scintigraphy was clearly higher than that by the sympathetic skin response, and some patients who had no sign on the sympathetic skin response showed the lowering of MIBG storage. The possibility of the failure of the norepinephrine transporter system was indicated as the main cause for the lowering of MIBG storage. (K.H.)

    Full Text Available Introduction. Cystic fibrosis (CF is a multisystemic autosomal recessive disease most frequently recognized by characteristic respiratory and/or digestive manifestations. Exceptionally rare, as is the case with the infant we are presenting, the initial sign of the disease can be nutritional deficiency dermatitis (NDD. Case Outline. A three-month-old male infant of young and healthy non-consanguineous parents, born at term after the first uneventful pregnancy, was hospitalized due to atopic dermatitis (AD-like skin changes, failure to thrive and normochromic anemia (Hb 60 g/L. As exclusively breast-fed, failure to thrive was attributed to hypogalactia and skin changes to nutritional allergy, so that, besides exclusion of cow’s milk protein and other highly allergenic foods in mother’s diet, hypoallergenic milk formula was added to the child’s diet. However, dietetic measures were without effect, and the child was re-hospitalized at age 4.5 months, this time in the condition of severe malnutrition with hypoproteinemic edemas, extensive dermatitis, moderate hepatosplenomegaly and recurrent normochromic anemia (Hb 57 g/L. After plasma-free erythrocyte transfusion, correction of hypoalbuminemia and two-week parenteral and semi-elementary nutrition resulted in gradual recovery of the child, also including the resolution of skin changes. Having in mind the clinical course of the disease, as well as the response to applied therapeutic measures, CF was suspected as the cause of the child’s problems, which was also confirmed by a high level of sweat chlorine (92 mmol/L and DNA analysis (∆F508/∆F508. Conclusion. Our experience indicates that NDD, as the initial manifestation of CF, should be also kept in mind in differential diagnosis of the infant’s AD-like changes.

    In chronic inflammatory bowel disease (IBD) (Crohn's disease [CD] and ulcerative colitis [UC]), symptoms from outside the gastrointestinal tract are frequently seen, and the joints, skin, eyes, and hepatobiliary area are the most usually affected sites (called extraintestinal manifestations [EIM]). The reported prevalence varies, explained by difference in study design and populations under investigation. The aim of our study was to determine the prevalence of EIM in a population-based inception cohort in Europe and Israel. IBD patients were incepted into a cohort that was prospectively followed from 1991 to 2004. A total of 1145 patients were followed for 10 years. The cumulative prevalence of first EIM was 16.9% (193/1145 patients) over a median follow-up time of 10.1 years. Patients with CD were more likely than UC patients to have immune-mediated (arthritis, eye, skin, and liver) manifestations: 20.1% versus 10.4% (p colitis compared to proctitis in UC increased the risk of EIM. In a European inception cohort, EIMs in IBD were consistent with that seen in comparable studies. Patients with CD are twice as likely as UC patients to experience EIM, and more extensive distribution of inflammation in UC increases the risk of EIM.

    Many different heritable connective tissue disorders (HCTD) have been described over the past decades. These syndromes often affect the connective tissue of various organ systems, including heart, blood vessels, skin, joints, bone, eyes, and lungs. The discovery of these HCTD was followed by the identification of mutations in a wide range of genes encoding structural proteins, modifying enzymes, or components of the TGFβ-signaling pathway. Three typical examples of HCTD are Marfan syndrome (MFS), Ehlers-Danlos syndrome (EDS), and Loeys-Dietz syndrome (LDS). These syndromes show some degree of phenotypical overlap of cardiovascular, skeletal, and cutaneous features. MFS is typically characterized by cardiovascular, ocular, and skeletal manifestations and is caused by heterozygous mutations in FBN1 , coding for the extracellular matrix (ECM) protein fibrillin-1. The most common cardiovascular phenotype involves aortic aneurysm and dissection at the sinuses of Valsalva. LDS is caused by mutations in TGBR1/2 , SMAD2/3 , or TGFB2/3 , all coding for components of the TGFβ-signaling pathway. LDS can be distinguished from MFS by the unique presence of hypertelorism, bifid uvula or cleft palate, and widespread aortic and arterial aneurysm and tortuosity. Compared to MFS, LDS cardiovascular manifestations tend to be more severe. In contrast, no association is reported between LDS and the presence of ectopia lentis, a key distinguishing feature of MFS. Overlapping features between MFS and LDS include scoliosis, pes planus, anterior chest deformity, spontaneous pneumothorax, and dural ectasia. EDS refers to a group of clinically and genetically heterogeneous connective tissue disorders and all subtypes are characterized by variable abnormalities of skin, ligaments and joints, blood vessels, and internal organs. Typical presenting features include joint hypermobility, skin hyperextensibility, and tissue fragility. Up to one quarter of the EDS patients show aortic aneurysmal

    2018-03-01

    Full Text Available Background/Aims: Pim-1 is a serine/threonine kinase that is highly expressed in the heart, and exerts potent cardiac protective effects through enhancing survival, proliferation, and regeneration of cardiomyocytes. Its myocardial specific substrates, however, remain unknown. In the present study, we aim to investigate whether Pim-1 modulates myofilament activity through phosphorylation of cardiac troponin I (cTnI, a key component in regulating myofilament function in the heart. Methods: Coimmunoprecipitation and immunofluorescent assays were employed to investigate the interaction of Pim-1 with cTnI in cardiomyocytes. Biochemical, site directed mutagenesis, and mass spectrometric analyses were utilized to identify the phosphorylation sites of Pim1 in cTnI. Myofilament functional assay using skinned cardiac fiber was used to assess the effect of Pim1-mediated phosphorylation on cardiac myofilament activity. Lastly, the functional significance of Pim1-mediated cTnI in heart disease was determined in diabetic mice. Results: We found that Pim-1 specifically interacts with cTnI in cardiomyocytes and this interaction leads to Pim1-mediated cTnI phosphorylation, predominantly at Ser23/24 and Ser150. Furthermore, our functional assay demonstrated that Pim-1 induces a robust phosphorylation of cTnI within the troponin complex, thus leading to a decreased Ca2+ sensitivity. Insulin-like growth factor 1 (IGF-1, a peptide growth factor that has been shown to stimulate myocardial contractility, markedly induces cTnI phosphorylation at Ser23/24 and Ser150 through increasing Pim-1 expression in cardiomyocytes. In a high-fat diabetic mice model, the expression of Pim1 in the heart is significantly decreased, which is accompanied by a decreased phosphorylation of cTnI at Ser23/24 and Ser150, further implicating the pathological significance of the Pim1/cTnI axis in the development of diabetic cardiomyopathy. Conclusion: Our results demonstrate that Pim-1 is a

    Full Text Available INTRODUCTION Myocardial infarction is a common and severe manifestation of ischaemic heart disease (IHD. Acute myocardial infarction (AMI is the result of death of heart muscle cells following either from a prolonged or severe ischaemia. The World Health Organisation emphasises IHD as our "Modern Epidemic" and AMI as common cause of sudden death. AIM The present study has been undertaken with the aim to assess the role of cardiac Troponin-T in early diagnosis of AMI and to evaluate its positive roles over CK-MB and LDH enzyme assays. The study also aims to find out the role of cardiac Troponin-T test, where ECG changes are nondiagnostic and inconclusive for AMI. MATERIAL & METHOD One hundred cases of provisionally diagnosed AMI, who were admitted during June 2012 to July 2015 in ICC Unit of TMC & Dr. BRAM Teaching Hospital, formed the subjects for the study. Those patients reported 2 to 10 hours after onset of chest pain were included in this study. Patients reported beyond 10 hours after onset of chest pain of AMI cases and patients having chest pain of non-AMI causes are excluded from the study. The provisional diagnosis of AMI was done on the basis of the history, chest pain, clinical findings and ECG changes. Trop-T test (Troponin-T sensitive rapid test by Muller Bardoff, et al, 1991 as well as CK-MB (creatine kinase-MB isoenzymeassays were performed immediately for each and every patient. Trop-T test was repeated in some selective cases where the early changes were insignificant and the results were compared with those of CK-MB, at different period of the disease onset. RESULTS The rapid cardiac Troponin-T test (CTn-T has 100% specificity for AMI whereas CK-MB and LDH have specificities of 80% and 60% respectively. The CTn-T has diagnostic efficiency of 92% for AMI but ECG has only 69% sensitivity and 80% specificity. The overall diagnostic efficacy of cardiac Troponin-T is higher than that of CK-MB, LDH and ECG (94% versus 92%, 91 % and 72

    In this case report, the history and imaging of two patients with invasive lobular carcinoma (ILC) in the skin are presented, followed by a discussion of both benign and malignant intradermal findings on breast ultrasound. Although the majority of dermal findings are benign, these cases are a reminder that malignancy can manifest within the skin. The purpose of presenting these cases together is to remind breast imagers of the importance of considering malignancy in the differential diagnosis of intradermal lesions on breast ultrasound, especially in special circumstances such as a personal history of breast cancer or associated clinical findings.

    Sclerodermatomyositis is an overlap syndrome of myositis and scleroderma, with dermatological, muscular and joint involvement, but may also present with ocular manifestations. A 57 year-old woman presented with ophthalmological manifestations, including scleral thinning 360°, and the presence of cells in the anterior and posterior chamber. Oriented physical examination and laboratory studies led to the diagnosis, with the need for systemic treatment. Sclerodermatomyositis is a rare disease. Its diagnosis needs thorough clinical and laboratory studies, and its management should be multidisciplinary when inflammatory ocular manifestations may be present.

Topical bovine thrombin has been used to promote hemostasis after surgical procedures for over 60 years and is used frequently as a topical hemostatic agent in cardiac surgery. Recently, use of bovine thrombin has been reported to be associated with increased risk for anaphylaxis, thrombosis, and immune-mediated coagulopathy thought secondary to the production of antifactor V and antithrombin antibodies. In patients who develop bovine thrombin-induced immune-mediated coagulopathy, clinical manifestations may range from asymptomatic alterations in coagulation tests to severe hemorrhage and death. Patients undergoing cardiac surgical procedures may be at increased risk for development of antibodies to bovine thrombin products and associated complications. This adverse immunologic profile has led to the development of alternative preparations including a human and a recombinant thrombin which have been shown to be equally efficacious to bovine thrombin and have reduced antigenicity. However, the potential benefit associated with reduced antigenicity is not truly known secondary to the lack of long-term experience with these products. Given the potentially higher margin of safety and less stringent storage concerns compared to human thrombin, recombinant thrombin may be the most reasonable approach in cardiac surgery.Keywords: bovine thrombin, human thrombin, recombinant thrombin, immune-mediated coagulopathy, topical hemostatic agents, thrombin

    The term barrier function as applied to human skin often connotes the physical properties of this organ that provides protection from its surrounding environment. This term does not generally include skin pigmentation. However, skin pigmentation, which is the result of melanin produced in melanocytes residing in the basal layer of the skin and exported to the keratinocytes in the upper layers, serves equally important protective function. Indeed, changes in skin pigmentation are often the most readily recognized indicators of exposure of skin to damaging agents, especially to natural and artificial radiation in the environment. Several recent studies have shed new light on (1) the mechanisms involved in selective effects of subcomponents of UV radiation on human skin pigmentation and (2) the interactive influences between keratinocytes and melanocytes, acting as "epidermal melanin unit," that manifest as changes in skin pigmentation in response to exposure to various forms of radiation. This article provides a concise review of our current understanding of the effects of the nonionizing solar radiation, at cellular and molecular levels, on human skin pigmentation. © 2012 Wiley Periodicals, Inc.

    Objective Tested the hypothesis that propranolol, a drug given to burn patients to reduce hypermetabolism/cardiac stress, may inhibit heat dissipation by changing the sensitivity of skin blood flow (SkBF) to local heating under neutral and hot conditions. Methods In a randomized double-blind study, a placebo was given to 8 burned children while propranolol was given to 13 burned children with similar characteristics (mean ± SD: 11.9±3y, 147±20cm, 45±23kg, 56±12% TBSA). Non-burned children (n=13, 11.4±3y, 152±15cm, 52±13kg) served as healthy controls. A progressive local heating protocol characterized SkBF responses in burned and unburned skin and non-burned control skin under the two environmental conditions (23°C and 34°C) via laser-Doppler flowmetry. Results Resting SkBF was greater in burned and unburned skin compared to the non-burned control (main effect: skin, Pburned; 38±36 unburned vs 9±8 control %SkBFmax). No difference was found for maximal SkBF capacity to local heating between groups. Additionally, dose response curves for the sensitivity of SkBF to local heating were not different among burned or unburned skin, and non-burned control skin (EC50, P>0.05) under either condition. Conclusion Therapeutic propranolol does not negatively affect SkBF under neutral or hot environmental conditions and further compromise temperature regulation in burned children. PMID:28071840

    Gerodermia osteodysplastica (GO) is a connective tissue disorder characterized by premature aging, wrinkled, and lax skin with reduced elasticity which is more marked on the dorsum of the hands and feet associated with hyperextensible joints and osteoporosis. The wrinkly skin syndrome (WSS) is characterized by wrinkled skin over the dorsum of the hands, feet, and abdomen; hyperextensible joints, particularly of the hands; intrauterine growth retardation; postnatal failure to thrive; and mental and developmental delay. We report on five children from two consanguineous Arab families with features overlapping both GO and WSS. All five children had similar dysmorphic facial features consisting of broad and prominent forehead, hypotelorism with epicanthal folds, prominent bulbous nose, flat malar region, and large protruding ears. All had wrinkling of the skin more marked on the dorsum of the hands, feet, and abdomen; hyperextensibility of the joints, particularly of the hands; and aged appearance. Intrauterine growth retardation, subsequent failure to thrive, developmental delay, and variable degree of osteoporosis was also present in all of them. The older three children developed progressive prognathism. We suggest that GO and WSS could represent variable manifestation of the same disorder. Copyright 2001 Wiley-Liss, Inc.

    2009-01-01

    Full Text Available Volatile anaesthetic agents have direct protective properties against ischemic myocardial damage. The implementation of these properties during clinical anaesthesia can provide an additional tool in the treatment or prevention, or both, of ischemic cardiac dysfunction in the perioperative period. A recent meta-analysis showed that desflurane and sevoflurane reduce postoperative mortality and incidence of myocardial infarction following cardiac surgery, with significant advantages in terms of postoperative cardiac troponin release, need for inotrope support, time on mechanical ventilation, intensive care unit and overall hospital stay. Multicentre, randomised clinical trials had previously demonstrated that the use of desflurane can reduce the postoperative release of cardiac troponin I, the need for inotropic support, and the number of patients requiring prolonged hospitalisation following coronary artery bypass graft surgery either with and without cardiopulmonary bypass. The American College of Cardiology/American Heart Association Guidelines recommend volatile anaesthetic agents during non-cardiac surgery for the maintenance of general anaesthesia in patients at risk for myocardial infarction. Nonetheless, e vidence in non-coronary surgical settings is contradictory and will be reviewed in this paper together with the mechanisms of cardiac protection by volatile agents.

    Full Text Available Characteristic skin lesions play a key role in clinical diagnosis of spotted fever group rickettsioses and this study describes these cutaneous manifestations along with basic histological features.Study was conducted at Medical Unit, Teaching Hospital, Peradeniya, from November 2009 to October 2011, where a prospective data base of all rickettsial infections is maintained. Confirmation of diagnosis was made when IgM and IgG immunofluorescent antibody titre of 1/32 and >1/256 respectively. Of the 210 clinical cases, 134 had cutoff antibody titers for Rickettsia conorii antigen for confirmation. All these 134 patients had fever and skin rash, and of them 132(98% had discrete maculopapular rash while eight (6% had fern leaf type skin necrosis. Eight patients (6% had healed tick bite marks. Average size of a skin lesion was 5 mm and rash involved 52% of body surface, distributed mainly in limbs and back of the chest. Generally the facial and leg skin was slightly oedematous particularly in old aged patients. Sixteen patients (12% had pain and swelling of ankle joints where swelling extended to feet and leg. Biopsies from skin rash of six patients showed evidence of cutaneous vasculitis and of them, 247 bp region of the 17-kDa spotted fever group specific protein antigen was amplified using PCR.A discrete maculopapular rash and occasional variations such as fern leaf shape necrosis and arthritis are found in spotted fever group. Histology found vasculitis as the pathology of these lesions.

    We investigate the effect of proton-skin thickness on the α decay process. We consider 188 neutron-deficient nuclei belonging to the isotopic chains from Te (Z = 52) to Pb (Z = 82). The calculations of the half-life are carried out in the framework of the preformed cluster model, with the Wentzel-Kramers-Brillouin penetration probability and assault frequency. It is shown that the proton-skin thickness ({\\varDelta }{{p}}) of the daughter nucleus gives rise to a total α- daughter nucleus interaction potential of relatively wide deep internal pocket and a thinner Coulomb barrier of less height. This increases the penetration probability but decreases the assault frequency. The overall impact of the proton-skin thickness appears as a decrease in the decay half-life. The proton-skin thickness decreases the stability of the nucleus. The half-lives of the proton-skinned isotopes along the isotopic chain decrease exponentially with increasing the proton-skin thickness, whereas the {Q}α -value increases with {\\varDelta }{{p}}. α-decay manifests itself as the second favorite decay mode of neutron-deficient nuclei, next to the {β }+-decay and before proton-decay. It is indicated as main, competing, and minor decay mode, at 21%, 7%, and 57%, respectively, of the investigated nuclei.

    How might the psycho-social effects of chronic skin disease, its treatments (and discontents) be figuratively expressed in writing and painting? Does the art reveal common denominators in experience and representation? If so, how do we understand the cryptic language of these expressions? By examining the works of artists with chronic skin diseases--John Updike, Elizabeth Bishop, and Zelda Fitzgerald--some common features can be noted. Chronically broken skin can fracture the ego or self-perception, resulting in a disturbed body image, which leads to personality disorders and co-morbid affective disorders such as anxiety and depression. The vertiginous feeling that results can be noted in the paradoxical characters, figures, and psyches portrayed in the works of these artists. This essay will examine the more specific ways in which artists disclose and/or conceal their experiences and the particular ways in which these manifest in their works. While certain nuances exist, the common denominators give us a starting point for developing an eczema aesthetic, a code for interpreting the ways in which artists' experiences with skin disease manifest in their works.

    Full Text Available Linna Guan,1 Amanda Suggs,1 Emily Galan,1 Minh Lam,1 Elma D Baron1,2 1Department of Dermatology, Case Western Reserve University, 2Cleveland Veterans Affairs Medical Center, Cleveland, OH, USA Abstract: Ultraviolet radiation (UVR has a significant impact on human skin and is the major environmental factor for skin cancer formation. It is also believed that 80% of the signs of skin aging are attributed to UVR. UVR induces inflammatory changes in the skin via the increase in oxidative stress, DNA damage vascular permeability, and fluctuation in a myriad of cytokines. Acutely, UVR causes skin inflammation and DNA damage, which manifest as sunburn (erythema. ST266 is the secretome of proprietary amnion-derived cells that have been shown to reduce inflammation and accelerate healing of various wounds by promoting migration of keratinocytes and fibroblasts in preclinical animal studies. We hypothesized that ST266 has anti-inflammatory effects that can be used to reduce ultraviolet (UV erythema and markers of inflammation. In this study, we examined the in vivo effects of ST266 on post UV-irradiated skin by measuring erythema, level of cyclobutane pyrimidine dimer (CPD, and expression level of xeroderma pigmentosum, complementation group A (XPA. We demonstrated that ST266 has the potential to reduce the acute effects of UV-induced skin damage when applied immediately after the initial exposure. In addition, ST266 is shown to reduce erythema, increase XPA DNA repair protein, and decrease damaged DNA. Keywords: ST266, photoaging, erythema, CPD, XPA, UV-induced DNA damage

    To investigate the patterns and risk factors of the ocular manifestations of acquired immunodeficiency syndrome (AIDS) and their correlation with CD4+ count in the era of highly active antiretroviral therapy (HAART). This retrospective study examined 127 AIDS patients who presented to Soonchunhyang University Hospital. Data were collected from patient interviews, clinical examinations, and laboratory investigations. Ophthalmologic examinations included the best-corrected visual acuity, intraocular pressure, anterior segment and adnexal examination, and dilated fundus examination. Of the 127 patients with AIDS, 118 were on HAART and 9 were not. The mean CD4+ count was 266.7 ± 209.1 cells/µL. There were ocular manifestations in 61 patients (48.0%). The incidence of anterior segment manifestations was higher than posterior segment manifestations at 28.3% and 19.7%, respectively. The mean CD4+ count was significantly (p AIDS. In this study, anterior segment and external ocular manifestations occurred more frequently than posterior segment manifestations. Also, the mean CD4+ count was significantly lower in patients with posterior segment ocular manifestations versus anterior segment ocular manifestations. We found that CD4+ count and age >35 years were independent risk factors for developing ocular manifestations.

    Full Text Available BACKGROUND: Skin atrophy is a common manifestation of aging and is frequently accompanied by ulceration and delayed wound healing. With an increasingly aging patient population, management of skin atrophy is becoming a major challenge in the clinic, particularly in light of the fact that there are no effective therapeutic options at present. METHODS AND FINDINGS: Atrophic skin displays a decreased hyaluronate (HA content and expression of the major cell-surface hyaluronate receptor, CD44. In an effort to develop a therapeutic strategy for skin atrophy, we addressed the effect of topical administration of defined-size HA fragments (HAF on skin trophicity. Treatment of primary keratinocyte cultures with intermediate-size HAF (HAFi; 50,000-400,000 Da but not with small-size HAF (HAFs; 400,000 Da induced wild-type (wt but not CD44-deficient (CD44-/- keratinocyte proliferation. Topical application of HAFi caused marked epidermal hyperplasia in wt but not in CD44-/- mice, and significant skin thickening in patients with age- or corticosteroid-related skin atrophy. The effect of HAFi on keratinocyte proliferation was abrogated by antibodies against heparin-binding epidermal growth factor (HB-EGF and its receptor, erbB1, which form a complex with a particular isoform of CD44 (CD44v3, and by tissue inhibitor of metalloproteinase-3 (TIMP-3. CONCLUSIONS: Our observations provide a novel CD44-dependent mechanism for HA oligosaccharide-induced keratinocyte proliferation and suggest that topical HAFi application may provide an attractive therapeutic option in human skin atrophy.

    Our purpose was to compile information on the haematological manifestations of systemic lupus erythematosus (SLE), namely leucopenia, lymphopenia, thrombocytopenia, autoimmune haemolytic anaemia (AIHA), thrombotic thrombocytopenic purpura (TTP) and myelofibrosis. During our search of the English-language MEDLINE sources, we did not place a date-of-publication constraint. Hence, we have reviewed previous as well as most recent studies with the subject heading SLE in combination with each manifestation. Neutropenia can lead to morbidity and mortality from increased susceptibility to infection. Severe neutropenia can be successfully treated with granulocyte colony-stimulating factor. While related to disease activity, there is no specific therapy for lymphopenia. Severe lymphopenia may require the use of prophylactic therapy to prevent select opportunistic infections. Isolated idiopathic thrombocytopenic purpura maybe the first manifestation of SLE by months or even years. Some manifestations of lupus occur more frequently in association with low platelet count in these patients, for example, neuropsychiatric manifestation, haemolytic anaemia, the antiphospholipid syndrome and renal disease. Thrombocytopenia can be regarded as an important prognostic indicator of survival in patients with SLE. Medical, surgical and biological treatment modalities are reviewed for this manifestation. First-line therapy remains glucocorticoids. Through our review, we conclude glucocorticoids do produce a response in majority of patients initially, but sustained response to therapy is unlikely. Glucocorticoids are used as first-line therapy in patients with SLE with AIHA, but there is no conclusive evidence to guide second-line therapy. Rituximab is promising in refractory and non-responding AIHA. TTP is not recognised as a criteria for classification of SLE, but there is a considerable overlap between the presenting features of TTP and SLE, and a few patients with SLE have concurrent

    Full Text Available Scrub typhus is caused by Orientia tsutsugamushi characterized by focal or disseminated vasculitis and perivasculitis which may involve the lungs, heart, liver, spleen and central nervous system. It was thought to have been eradicated from India. Recently it is being reported from many areas of India. The clinical picture and severity of the symptoms varies widely. The neurological manifestations of scrub typhus are not uncommon but are diverse. Meningoencephalitis is classical manifestation of scrub typhus but cerebellitis, cranial nerve palsies, plexopathy, transverse myelitis, neuroleptic malignant syndrome and Guillan-Barré syndrome are other manifestations reported in literature. The availability of literature on the neurological manifestations of scrub typhus is limited to case reports mainly. This article reviews various neurological manifestations of scrub typhus reported in literature.

    Most thoracopagus twins present with cardiac fusion and associated congenital cardiac defects, and assessment of this anatomy is of critical importance in determining patient care and outcome. Cardiac CT with electrocardiographic triggering provides an accurate and quick morphological assessment of both intracardiac and extracardiac structures in newborns, making it the best imaging modality to assess thoracopagus twins during the neonatal period. In this case report, we highlight the diagnostic value of cardiac CT in thoracopagus twins with an interatrial channel and complex congenital cardiac defects. (orig.)

    In the USA, Europe and Japan 40 to 50% of women report that they have sensitive skin, defined as abnormal sub-clinical sensory responses to drugs, cosmetics and toiletries in the absence of visible signs of irritation. Itching, burning, stinging and tightness are the commonest complaints, which mainly afflict women. Manufacturers of skin care products have made available a large variety of products which are designed for persons with sensitive skin. Such products are not required by regulatory agencies to submit evidence of safety and efficacy, allowing marketers to make claims that are often exaggerated, irrational and even preposterous. The consumer with self-assessed sensitive skin has no way of judging which products are likely to be most beneficial and least harmful. The marketplace is awash with products for which there is no evidence that the rosy claims have been substantiated by appropriate testing procedures. There is no internationally accepted consensus regarding the criteria which define sensitive skin. Many papers have been published in the last 15 years, mainly originating from industry, which express widely differing views regarding what constitutes sensitive skin. For some, any adverse reaction to a product topically applied to sensitive skin, including breakouts, redness, scaling etc., a panoply of adverse reactions which is virtually meaningless. Others include environmental factors as causative, including cold, dry wind, heat and high humidity, solar radiation, etc., which add to the manifest complexities of the subject. This is the first paper in a series which provides a comprehensive review of the subject, emphasizing the all too many controversies and confusions arising from the lack of a consensus regarding the identification, classification, epidemiology, prevalence and pathogenesis of sensitive skin. Sensitive skin is a biologic reality and not a psychological, fashionable fantasy on the part of impressionable women. There is an urgent

    Antiphospholipid antibody is associated with a clinical syndrome of vascular thrombosis, thrombocytopenia, recurrent fetal loss and livedo reticularis, whether or not a clinical diagnosis of systemic lupus erythematosus (SLE) coexists. Central nervous system involvement in SLE is multifactorial, thrombotic events, antineuronal antibodies, hypertension, infection, side effects of drugs etc. Antiphospholipid antibodies may play a role in focal neurological manifestations in SLE. In the absence of SLE, different neurological symptoms are well associated with antiphospholipid antibodies including stroke, seizures, dementia, migraine, ocular ischemia, chorea, transverse myelopathy, cerebral phlebitis. Other association are more controversal like Guillain Barré syndrome, motor neuron disease, communicating hydrocephalus. In all patients with antiphospholipid antibodies with neurological involvement, cerebral MRI may be performed with an echocardiographic study because a possible association with Libman and Sacks endocarditis, valve dysfunction or cardiac thrombus source of cerebral ischemia.

    We investigated whether forearm skin blood flow could be improved when a multilayer pulsatile inflatable suit was applied at a low pressure to the lower limbs and abdomen. We hypothesized that a non-invasive purely mechanical stimulation of the lower limbs could induce remote forearm blood flow modifications. The pulsatile suit induced a sequential compartmentalized low compression (65 mmHg), which was synchronized with each diastole of the cardiac cycle with each phase evolving centripetally (lower limbs to abdomen). Modifications of the forearm skin blood flow were continuously recorded by laser Doppler flowmetry (LDF) at baseline and during the pulsatile suit application. Endothelium-dependent and endothelium-independent vasodilations of the forearm skin microcirculation were measured by LDF in response to a local transdermal iontophoretic application of acetylcholine (ACh-test) and to hyperthermia (hyperT- test). Twenty-four healthy volunteers, 12 men and 12 women (43±14 years) were included in the study. LDF responses increased 1) under pulsatile suit (97±106%, p.

    Full Text Available At the beginning of a new millennium, syphilis incidence has been increasing worldwide, occurring primarily among men who have sex with men (MSM. The clinical features of primary syphilis among MSM is described, a case-note review of the primary syphilis (PS patients who attended the Institute of Skin and Venereal Diseases. The diagnosis was assessed based upon the clinical features and positive syphilis serology tests. Among 25 patients with early syphilis referred during 2010, PS was diagnosed in a total of 13 cases. In all patients, unprotected oral sex was the only possible route of transmission, and two out of 13 patients had HIV co-infection. Overall, 77% of men presented with atypical penile manifestation. The VDRL test was positive with low titers. The numerous atypical clinical presentations of PS emphasize the importance of continuing education of non-experienced physicians, especially in countries with lower reported incidence of syphilis.

    Full Text Available Cow’s milk protein allergy (CMPA is the leading cause of food allergy in children under three years of age, although its gastrointestinal manifestations may occur in all age groups. In the suspicion of CMPA based on the anamnesis and physical examination, an elimination diet should be initiated for a variable length of time according to the clinical picture, followed by an oral food challenge (OFC confi rming or excluding the diagnosis. Complementary exams such as skin prick tests and specifi c IgE may be necessary. Treatment is based on an elimination diet and demands nutritional counselling and growth monitoring. Usually an OFC is repeated after three to 12 months of elimination diet. Tolerance is achieved at three years of age in more than 80% of the children. The aim of this work is to make a brief review and update on CMPA in pediatric age, proposing a management approach based on recent international recommendations.

    Ectodermal dysplasias (EDs) are a group of genodermatoses characterized by malformations of tissues derived from the ectoderm, including the skin, its appendages (hair, nails, sweat glands), teeth, and the breasts. Ectodermal dysplasia syndactyly syndrome (EDSS) is a rare, newly described type of ED involving syndactyly. We report 2 Yemeni siblings with typical EDSS manifestations, including bilateral, partial cutaneous syndactyly of the fingers and toes; sparse, coarse, brittle scalp hair, eyebrows, and eyelashes; and conical, widely spaced teeth with enamel notches. In addition, the siblings presented with other features hitherto not described for this syndrome, such as adermatoglyphia, onychogryphosis, hypoplastic widely spaced nipples, hypoplastic thumbs, and red scalp hair.

    Full Text Available We report 2 cases that were considered to be neuro-Sweet disease. They initially manifested with meningoencephalitis and no skin lesions, and rapidly improved with corticosteroid therapy. In both cases, patients complained of meningitic symptoms such as fever and headache, and HLA-B54 and -Cw1 turned out to be positive over the clinical course. Cerebrospinal fluid analysis showed increased levels of lymphocytes and protein. In case #1, fluid-attenuated inversion recovery (FLAIR, magnetic resonance imaging (MRI and diffusion-weighted images (DWI showed high-intensity signals in the right dorsal medulla oblongata, bilateral dorsal midbrain, and left thalamus. In case #2, FLAIR and DWI showed high-intensity signals in the bilateral cerebellar cortex and left caudate nucleus. Symptoms and MRI images were markedly improved in both cases after corticosteroid pulse therapy. According to published diagnostic criteria, these 2 cases were considered possible neuro-Sweet disease. These cases suggest that the combination of meningoencephalitis and HLA specificity is important to consider the possibility of neuro-Sweet disease, even without skin lesions.

    Ritscher-Schinzel syndrome (also known as cranio-cerebello-cardiac dysplasia or 3C syndrome) is a rare genetic syndrome that is mainly characterised by the association of cardiac and craniofacial anomalies together with others affecting the posterior fossa. We report on 26 patients with Ritscher-Schinzel syndrome at a hospital in Medellin, in the Department of Antioquia, Colombia. Males account for 69% of this cohort. The mean age of the cohort was 30 months, and 42% were under the age of one year at the time of diagnosis. All of them presented ocular disorders, and megalocornea was the most frequent ocular manifestation (69%), whereas low-set ears (80.7%) and septal heart defects (68.7%) were the most common facial and cardiac malformations, respectively. The most frequent malformations of the posterior fossa were megacisterna magna (31.8%) and Dandy-Walker malformation (27%). 84% of the cases had delayed neurodevelopment or intellectual disability. Skeletal manifestations were frequent: the group consisting of camptodactyly, single palmar crease, overlapping fingers, vertical talus and nail hypoplasia were found in hands and feet in 96% of the cases. Ritscher-Schinzel syndrome is a heterogeneous syndrome from the genetic and clinical point of view. These results suggest that the skeletal and ocular abnormalities that were observed can facilitate the phenotypic diagnosis. However, it is necessary to conduct further studies that allow us to gain a deeper knowledge of its prevalence and help identify other genes involved in this syndrome.

    Infants and children are a higher risk population for radiation cancer induction compared to adults. Although some values on pediatric patient doses for cardiac procedures have been reported, data to determine reference levels are scarce, especially when compared to those available for adults in diagnostic and therapeutic procedures. The aim of this study is to make a new contribution to the scarce published data in pediatric cardiac procedures and help in the determination of future dose reference levels. This paper presents a set of patient dose values, in terms of air kerma area product (KAP) and entrance surface air kerma (ESAK), measured in a pediatric cardiac catheterization laboratory equipped with a biplane x-ray system with dynamic flat panel detectors. Cardiologists were properly trained in radiation protection. The study includes 137 patients aged between 10 days and 16 years who underwent diagnostic catheterizations or therapeutic procedures. Demographic data and technical details of the procedures were also gathered. The x-ray system was submitted to a quality control programme, including the calibration of the transmission ionization chamber. The age distribution of the patients was 47 for 2 respectively for the four age bands. These KAP values increase by a factor of 8 when moving through the four age bands. The probability of a fatal cancer per fluoroscopically guided cardiac procedure is about 0.07%. Median values of ESAK for the four age bands were 46, 50, 56 and 163 mGy, which lie far below the threshold for deterministic effects on the skin. These dose values are lower than those published in previous papers

    Full Text Available The most common skin malignant tumor of the epidermoid origin are basal cell (BCC and squamous cell (SCC carcinoma. They occur at the photoexposed parts of the body in 90% of cases and are directly associated with skin damage caused by long term exposure to UV rays, usually in older persons and light skin. Almost 65,000 people die annually in the world from their consequences. The most important link in preventing the occurrence of these tumors is prevention, but their early identification allows adequate surgical treatment with sparing surrounding tissue. The main objective of this paper is to examine the histopathological and clinical-morphological characteristics of BCC and SCC of the skin of the head. The analysis included 439 cancer (297 (67.7% BCC, 126 (28.7% SCK and 16 (3.6% BCK + SCK, among which over 60% were diagnosed in men, usually in the seventh and eighth decade of life, with the highest incidence of BCC on the nose or on the skin of the upper half of the face and SCK on the lips or the skin of the lower half of face. All skin cancers of the head were more common on the right side. Clinical and morphological, most of the BCC were manifested by ulcerative form of average size 1.2cm and mixed histological type, and SCK by vegetative form of average size 1.55cm and histological grade I. The highest number of BCC and SCC was completly removed, in contrast to the combination of these two tumors among them in most cases the subsequent surgical intervention was necessary.

    Cardiac auscultation is a cost-effective, noninvasive screening tool that can provide information about cardiovascular hemodynamics and disease. However, with advances in imaging and laboratory tests, the importance of cardiac auscultation is less appreciated in clinical practice. The widespread use of smartphones provides opportunities for nonmedical expert users to perform self-examination before hospital visits. The objective of our study was to assess the feasibility of cardiac auscultation using smartphones with no add-on devices for use at the prehospital stage. We performed a pilot study of patients with normal and pathologic heart sounds. Heart sounds were recorded on the skin of the chest wall using 3 smartphones: the Samsung Galaxy S5 and Galaxy S6, and the LG G3. Recorded heart sounds were processed and classified by a diagnostic algorithm using convolutional neural networks. We assessed diagnostic accuracy, as well as sensitivity, specificity, and predictive values. A total of 46 participants underwent heart sound recording. After audio file processing, 30 of 46 (65%) heart sounds were proven interpretable. Atrial fibrillation and diastolic murmur were significantly associated with failure to acquire interpretable heart sounds. The diagnostic algorithm classified the heart sounds into the correct category with high accuracy: Galaxy S5, 90% (95% CI 73%-98%); Galaxy S6, 87% (95% CI 69%-96%); and LG G3, 90% (95% CI 73%-98%). Sensitivity, specificity, positive predictive value, and negative predictive value were also acceptable for the 3 devices. Cardiac auscultation using smartphones was feasible. Discrimination using convolutional neural networks yielded high diagnostic accuracy. However, using the built-in microphones alone, the acquisition of reproducible and interpretable heart sounds was still a major challenge.

    The clinical presentations of skin diseases produced by different pathogens, as American tegumentary leishmaniasis (ATL) and sporotrichosis can be similar and possibly influenced by the skin immune system (SIS). The aim of the study was to understand the underlying mechanisms of skin inflammation produced by different pathogens. We used immunohistochemistry to analyze 96 patients: a- localized cutaneous leishmaniasis (LCL-ATL); b- sporotrichoid cutaneous leishmaniasis (SCL-ATL); c-lymphocutaneous (LC-SP); d- fixed (F-SP) sporotrichosis. LCL-ATL and SCL-ATL had a significantly higher percentage of CD8, FasL and NOS2 than sporotrichosis. In contrast, LC-SP had a substantially higher percentage of CD4, BCl2 and neutrophils than ATL lesions. These results indicated some differences in the profile of the in situ immune response suggesting that SIS is a complex, adaptable system capable of different responses to intracellular or extracellular pathogens. However, regardless of the etiological agents, the inflammatory reaction and clinical manifestations can be similar. SCL-ATL and LC-SP presented similarities in both clinical presentation and in situ inflammatory profile (CD3, CD22, neutrophils, macrophages). The clinical presentation of ATL and sporotrichosis could be explained by a combination of factors both of the host SIS and the etiological agent. The unbalanced host parasite relationship could result in atypical manifestations of skin disease.

    Xeroderma pigmentosum is a rare, autosomal recessive disease caused by a defect in DNA repair. Patients with xeroderma pigmentosum often have cutaneous and ocular sun sensitivity, freckle-like skin pigmentation, multiple skin and eye cancers, and, in some patients, progressive neurodegeneration. Xeroderma pigmentosum predominantly affects the ultraviolet (UV) exposed ocular surface, resulting in eyelid atrophy and cancers, corneal dryness, exposure keratopathy, and conjunctival tumors. We report the clinical history and ocular pathology of two white women who had xeroderma pigmentosum with neurological degeneration: Case 1 (died at age 44 years) and Case 2 (died at age 45 years). Case 1, with mutations in the XPA gene, had more than 180 basal cell carcinomas of her skin and eyelids and died from complications of neurodegeneration. Case 2, with mutations in the XPD gene, was sun-protected and had three skin cancers. She died from complications of neurodegeneration and pneumonia. Both patients had bilateral pinguecula, corneal pannus, and exposure keratopathy. Case 1 had bilateral optic atrophy, and Case 2 had bilateral peripheral retinal pigmentary degeneration. Both patients developed retinal gliosis. The ophthalmic manifestations and pathology of xeroderma pigmentosum are discussed and reviewed with respect to this report and other cases in the literature. These cases illustrate the role of DNA repair in protection of the eyes from UV damage and neurodegeneration of the retina. Published by Elsevier Inc.

    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.

    The response to the light on the skin can be manifested as temperature increase or creation of biochemical byproducts, in which further studies are required to asset the light effect. This response changes the average response over time and can produce discrepancies between similar studies. In this work we present a Low Level Laser Therapy (LLLT) study with feedback. We study the time response reflectivity of a 980 nm laser diode of 25 mW modulated at frequencies close to 40 kHz and detect the reflected light on a silicon photodiode, finding no direct correlation between different test points or individuals, while finding reproducible responses within the same individual and test point

    Full Text Available Abstract Introduction Graves’ hyperthyroidism has a number of well-recognized but relatively rare extrathyroid manifestations such as thyroid acropachy, pretibial myxedema, and congestive heart failure. Case presentation A 38-year-old Caucasian woman presented to the out-patient clinic with symptoms of hyperthyroidism lasting for approximately five months. Remarkably, she had developed pitting edema of her left leg four months before. She had gone through a conventional assessment, but the reason for the edema was not revealed. At presentation to the endocrinology clinic, the skin of both legs was of normal color and pitting edema on her left leg was of a diffuse nature and spread from her toes to two thirds of her leg. The skin surface of her left leg was smooth and had no elevations or discoloration, whereas her right leg appeared normal. Based on signs and symptoms of thyrotoxicosis and suppressed thyroid-stimulating hormone level (less than 0.001mIU/L, local reference of 0.4 to 4, treatment of 10mg of thiamazole three times a day was started. Additional blood tests revealed marked Graves’ hyperthyroidism with elevated free T4 and anti-thyroid receptor antibodies. Within a month, the free T4 level was normalized and the edema was completely cleared and never reappeared during the treatment course of 12 months. Conclusions To the best of our knowledge, this is the first description of unilateral treatment-responsive leg edema as a manifestation of Graves’ hyperthyroidism. However, the pathophysiological mechanism underlying this case of edema remains unclear.

    2016-01-01

    Besides the lungs, tuberculosis (TB) can affect any organ system. In most cases, extrathoracic TB occurs in immunosuppressed patients as part of a severe illness via hematogenous spread. Extrathoracic involvement most commonly involves abdominal organs, especially the urogenital tract and less commonly the central nervous system (CNS) and the musculoskeletal system. Most frequently, computed tomography (CT) is used for detecting extrathoracic TB manifestations, except for CNS and musculoskeletal manifestations, where contrast-enhanced magnetic resonance imaging (MRI) is the gold standard. Extrathoracic manifestations of TB may be indistinguishable from inflammatory or malignant causes. Due to unspecific symptoms the diagnosis is often delayed. This article summarizes and discusses the various radiological manifestations of extrathoracic manifestation of TB. Radiological modalities for screening extrathoracic TB are CT and MRI. Conventional X-radiographs do not play a role in the diagnosis of extrathoracic TB. The possibility of extrathoracic TB should be considered particularly in immunosuppressed patients, such as the homeless, alcoholics or drug addicts or in patients with an immigrant background from the endemic areas of TB. The most likely site of extrathoracic TB is the abdomen; however, infections of the CNS or musculoskeletal systems and multisystem infections can also occur. In patients with suspected extrathoracic TB, radiological modalities for screening are CT, especially for abdominal infections and lymphadenopathy and MRI with contrast media for the musculoskeletal system and the CNS.

    2012-04-01

    Generalized peeling skin syndrome (PSS) is a rare autosomal recessive dermatosis manifesting with continuous exfoliation of the stratum corneum. The inflammatory (type B) subtype of PSS was recently found to be caused by deleterious mutations in the CDSN gene encoding corneodesmosin, a major component of desmosomal junctions in the uppermost layers of the epidermis. In the present study, we assessed a 10-month-old baby, who presented with generalized superficial peeling of the skin. Using PCR amplification and direct sequencing, we identified the third PSS-associated mutation in CDSN, a homozygous 4 bp duplication in the second exon of the gene (c.164_167dup GCCT; p.Thr57ProfsX6). These data further support the notion that corneodesmosin deficiency impairs cell-cell adhesion in the upper epidermis, paving the way for an abnormal inflammatory response due to epidermal barrier disruption.

    A thorough understanding of the cellular and muscle fiber orientation in left ventricular cardiac tissue is of paramount importance for the generation of artificial cardiac patches to treat the ischemic myocardium. The major challenge faced during cardiac patch engineering is to choose a perfect combination of three entities; cells, scaffolds and signaling molecules comprising the tissue engineering triad for repair and regeneration. This review provides an overview of various scaffold materials, their mechanical properties and fabrication methods utilized in cardiac patch engineering. Stem cell therapies in clinical trials and the commercially available cardiac patch materials were summarized in an attempt to provide a recent perspective in the treatment of heart failure. Various tissue engineering strategies employed thus far to construct viable thick cardiac patches is schematically illustrated. Though many strategies have been proposed for fabrication of various cardiac scaffold materials, the stage and severity of the disease condition demands the incorporation of additional cues in a suitable scaffold material. The scaffold may be nanofibrous patch, hydrogel or custom designed films. Integration of stem cells and biomolecular cues along with the scaffold may provide the right microenvironment for the repair of unhealthy left ventricular tissue as well as promote its regeneration.

    Complex percutaneous interventions often require high radiation doses likely to produce skin radiation injuries. We assessed the methodology used to select patients with potential skin injuries in cardiac procedures and in need of clinical follow-up. We evaluated peak skin dose and clinical follow-up in a case of radiodermatitis produced during a total occlusion recanalization. This prospective study followed CIRSE and ACC/AHA/SCAI recommendations for patient radiation dose management in interventional procedures carried out in a university hospital with a workload of 4200 interventional cardiac procedures per year. Patient dose reports were automatically transferred to a central database. Patients exceeding trigger levels for air kerma area product (500 Gy cm 2 ) and cumulative skin dose (5 Gy) were counseled and underwent follow-up for early detection of skin injuries, with dermatologic support. The Ethical Committee and the Quality Assurance and Radiation Safety Committee approved the program. During 2010, a total of 13 patients (3.0/1,000 that year) received dose values exceeding trigger levels in the cardiovascular institute. Only one patient, who had undergone two consecutive procedures resulting in 970 Gy cm 2 and 13.0 Gy as cumulative skin dose, showed signs of serious radiodermatitis that resolved in 3.7 months. The remaining patients did not manifest skin lesions during follow-up, and whenever patient examination was not feasible as part of the follow-up, neither patients nor families reported any skin injuries. Peak skin dose calculation and close clinical follow-up were feasible and appropriate, with a moderate additional workload for the staff and satisfaction for the patient.

    Full Text Available IntroductionThe purpose of this retrospective study was to report neurological manifestations noted in patients who were monitored for inflammatory bowel disease, in order to document the pathophysiological, clinical, progressive, and therapeutic characteristics of this entity.Material and methodsWe conducted a retrospective study on patients monitored -in the gastroenterology service in Ibn Sina Hospital in Rabat, Morocco- for inflammatory bowel disease from 1992 till 2013 and who developed neurological manifestations during its course. Patients with iatrogenic complications were excluded, as well as patients with cerebrovascular risk factors.ResultsThere were 6 patients, 4 of whom have developed peripheral manifestations. Electromyography enabled the diagnosis to be made and the outcome was favorable with disappearance of clinical manifestations and normalization of the electromyography.The other 2 patients, monitored for Crohn’s disease, developed ischemic stroke. Cerebral computed tomography angiography provided positive and topographic diagnosis. Two patients were admitted to specialized facilities.ConclusionNeurological manifestations in inflammatory bowel disease are rarely reported.  Peripheral neuropathies and stroke remain the most common manifestations. The mechanisms of these manifestations are not clearly defined yet. Currently, we hypothesize the interaction of immune mediators.

    Many diseases, as well as side effects of drugs, manifest themselves through skin symptoms. Skin is a complex tissue that hosts various specialized cell types and performs many roles including physical barrier, immune and sensory functions. Therefore, modeling skin in vitro presents technical challenges for tissue engineering. Since the first attempts at engineering human epidermis in 1970s, there has been a growing interest in generating full-thickness skin constructs mimicking physiological functions by incorporating various skin components, such as vasculature and melanocytes for pigmentation. Development of biomimetic in vitro human skin models with these physiological functions provides a new tool for drug discovery, disease modeling, regenerative medicine and basic research for skin biology. This goal, however, has long been delayed by the limited availability of different cell types, the challenges in establishing co-culture conditions, and the ability to recapitulate the 3D anatomy of the skin. Recent breakthroughs in induced pluripotent stem cell (iPSC) technology and microfabrication techniques such as 3D-printing have allowed for building more reliable and complex in vitro skin models for pharmaceutical screening. In this review, we focus on the current developments and prevailing challenges in generating skin constructs with vasculature, skin appendages such as hair follicles, pigmentation, immune response, innervation, and hypodermis. Furthermore, we discuss the promising advances that iPSC technology offers in order to generate in vitro models of genetic skin diseases, such as epidermolysis bullosa and psoriasis. We also discuss how future integration of the next generation human skin constructs onto microfluidic platforms along with other tissues could revolutionize the early stages of drug development by creating reliable evaluation of patient-specific effects of pharmaceutical agents.

    2016-09-01

    Full Text Available Cardiac remodeling occurs after cardiac pressure/volume overload or myocardial injury during the development of heart failure and is a determinant of heart failure. Preventing or reversing remodeling is a goal of heart failure therapy. Human cardiomyocyte Na+/K+-ATPase has multiple α isoforms (1-3. The expression of the α subunit of the Na+/K+-ATPase is often altered in hypertrophic and failing hearts. The mechanisms are unclear. There are limited data from human cardiomyocytes. Abundant evidences from rodents show that Na+/K+-ATPase regulates cardiac contractility, cell signaling, hypertrophy and fibrosis. The α1 isoform of the Na+/K+-ATPase is the ubiquitous isoform and possesses both pumping and signaling functions. The α2 isoform of the Na+/K+-ATPase regulates intracellular Ca2+ signaling, contractility and pathological hypertrophy. The α3 isoform of the Na+/K+-ATPase may also be a target for cardiac hypertrophy. Restoration of cardiac Na+/K+-ATPase expression may be an effective approach for prevention of cardiac remodeling. In this article, we will overview: (1 the distribution and function of isoform specific Na+/K+-ATPase in the cardiomyocytes. (2 the role of cardiac Na+/K+-ATPase in the regulation of cell signaling, contractility, cardiac hypertrophy and fibrosis in vitro and in vivo. Selective targeting of cardiac Na+/K+-ATPase isoform may offer a new target for the prevention of cardiac remodeling.

    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.

    Individuals with obsessive-compulsive features frequently visit dermatologists for complaints of the skin, hair or nails, and often progress towards a chronic relapsing course due to the challenge associated with accurate diagnosis and management of their psychiatric symptoms. The current DSM-5 formally recognizes body dysmorphic disorder, trichotillomania, neurotic excoriation and body focused repetitive behavior disorder as psychodermatological disorders belonging to the category of Obsessive-Compulsive and Related Disorders. However there is evidence that other relevant skin diseases such as delusions of parasitosis, dermatitis artefacta, contamination dermatitis, AIDS phobia, trichotemnomania and even lichen simplex chronicus possess prominent obsessive-compulsive characteristics that do not necessarily fit the full diagnostic criteria of the DSM-5. Therefore, to increase dermatologists' awareness of this unique group of skin disorders with OCD features, we propose a novel classification system called Obsessive-Compulsive Insight Continuum. Under this new classification system, obsessive-compulsive skin manifestations are categorized along a continuum based on degree of insight, from minimal insight with delusional obsessions to good insight with minimal obsessions. Understanding the level of insight is thus an important first step for clinicians who routinely interact with these patients.

    Skin and soft tissue infections are frequent contributors to morbidity and mortality in the immunocompromised host. This article reviews the changing epidemiology and clinical manifestations of the most common cutaneous pathogens in non-HIV immunocompromised hosts, including patients with solid organ transplants, stem cell transplants, solid tumors, hematologic malignancies, and receiving chronic immunosuppressive therapy for inflammatory disorders. Defects in the innate or adaptive immune response can predispose the immunocompromised host to certain cutaneous infections in a predictive fashion. Cutaneous lesions in patients with neutrophil defects are commonly due to bacteria, Candida, or invasive molds. Skin lesions in patients with cellular or humoral immunodeficiencies can be due to encapsulated bacteria, Nocardia, mycobacteria, endemic fungal infections, herpesviruses, or parasites. Skin lesions may reflect primary inoculation or, more commonly, disseminated infection. Tissue samples for microscopy, culture, and histopathology are critical to making an accurate diagnosis given the nonspecific and heterogeneous appearance of these skin lesions due to a blunted immune response. As the population of non-HIV immunosuppressed hosts expands with advances in medical therapies, the frequency and variety of cutaneous diseases in these hosts will increase.

    Patients recovering from cardiac events are increasingly using postacute care, such as home health care and skilled nursing facility services. The purpose of this pilot study was to test the initial efficacy, feasibility, and safety of a specially designed postacute care transitional rehabilitation intervention for cardiac patients. Cardiac Transitional Rehabilitation Using Self- Management Techniques (Cardiac TRUST) is a family-focused intervention that includes progressive low-intensity walking and education in self-management skills to facilitate recovery following a cardiac event. Using a randomized two-group design, exercise self-efficacy, steps walked, and participation in an outpatient cardiac rehabilitation program were compared in a sample of 38 older adults; 17 who received the Cardiac TRUST program and 21 who received usual care only. At discharge from postacute care, the intervention group had a trend for higher levels of self-efficacy for exercise outcomes (X=39.1, SD=7.4) than the usual care group (X=34.5; SD=7.0) (t-test 1.9, p=.06). During the 6 weeks following discharge, compared with the usual care group, the intervention group had more attendance in out-patient cardiac rehabilitation (33% compared to 11.8%, F=7.1, p=.03) and a trend toward more steps walked during the first week (X=1,307, SD=652 compared to X=782, SD=544, t-test 1.8, p=.07). The feasibility of the intervention was better for the home health participants than for those in the skilled nursing facility and there were no safety concerns. The provision of cardiac-focused rehabilitation during postacute care has the potential to bridge the gap in transitional services from hospitalization to outpatient cardiac rehabilitation for these patients at high risk for future cardiac events. Further evidence of the efficacy of Cardiac TRUST is warranted. PMID:22084960

    Lyme borreliosis (LB) is the most prevalent tick-borne disease in Europe. Erythema migrans (EM), an early, localised skin rash, is its most common presentation. Dissemination of the bacteria can lead to more severe manifestations including skin, neurological, cardiac, musculoskeletal and ocular manifestations. Comparison of LB incidence rates in the European Union (EU)/European Economic Area (EEA) and Balkan countries are difficult in the absence of standardised surveillance and reporting procedures. We explored six surveillance scenarios for LB surveillance in the EU/EEA, based on the following key indicators: (i) erythema migrans, (ii) neuroborreliosis, (iii) all human LB manifestations, (iv) seroprevalence, (v) tick bites, and (vi) infected ticks and reservoir hosts. In our opinion, neuroborreliosis seems most feasible and useful as the standard key indicator, being one of the most frequent severe LB manifestations, with the possibility of a specific case definition. Additional surveillance with erythema migrans as key indicator would add value to the surveillance of neuroborreliosis and lead to a more complete picture of LB epidemiology in the EU/EEA. The other scenarios have less value as a basis for EU-level surveillance, but can be considered periodically and locally, as they could supply complementary insights.

    Tuberculosis (TB) is a granulomatous disease caused by Mycobacterium tuberculosis and transmission is via an airborne route by droplet infection. In the majority of cases patients have thoracic TB, which most frequently presents with hilar lymphadenopathy and pulmonary manifestation. Due to the rise in incidence of TB in central Europe to be expected over the coming years, it is essential to be acquainted with the radiological manifestations of pulmonary TB, particularly to be able to discriminate active from inactive TB. Due to the use of molecular techniques entailing DNA fingerprinting, the traditional classification of TB in primary and postprimary TB is being challenged. These genetic studies have revealed that variations in the clinical and radiographic appearance of TB are mainly affected by the immune status of the patients. Due to the low prevalence of TB in central Europe and the wide variation of radiological presentations, the diagnosis and therapy of TB is often delayed. In this article, the radiographic manifestations of thoracic TB are summarized and discussed. Together with the medical history and bacteriological tests, chest X-ray imaging and computed tomography (CT) play a major role not only in the detection of TB but also in the follow-up during and after therapy. Chest X-radiographs should be the primary diagnostic method in patients with suspected TB in screening as well as for diagnosis and therapy monitoring. The use of CT is more sensitive than chest radiographs and is frequently performed after chest radiographs to obtain detailed information about subtle parenchymal changes or lymph node manifestation. When active TB is suspected CT should be performed. Tree in bud, lobular consolidations, centrilobular nodules, cavities and ground-glass opacification are typical changes in active TB. (orig.)

    Few data on the definition of simple robust parameters to predict image noise in cardiac computed tomography (CT) exist. To evaluate the value of a simple measure of subcutaneous tissue as a predictor of image noise in cardiac CT. 86 patients underwent prospective ECG-gated coronary computed tomographic angiography (CTA) and coronary calcium scoring (CAC) with 120 kV and 150 mA. The image quality was objectively measured by the image noise in the aorta in the cardiac CTA, and low noise was defined as noise < 30HU. The chest anteroposterior diameter and lateral width, the image noise in the aorta and the skin-sternum (SS) thickness were measured as predictors of cardiac CTA noise. The association of the predictors and image noise was performed by using Pearson correlation. The mean radiation dose was 3.5 ± 1.5 mSv. The mean image noise in CT was 36.3 ± 8.5 HU, and the mean image noise in non-contrast scan was 17.7 ± 4.4 HU. All predictors were independently associated with cardiac CTA noise. The best predictors were SS thickness, with a correlation of 0.70 (p < 0.001), and noise in the non-contrast images, with a correlation of 0.73 (p < 0.001). When evaluating the ability to predict low image noise, the areas under the ROC curve for the non-contrast noise and for the SS thickness were 0.837 and 0.864, respectively. Both SS thickness and CAC noise are simple accurate predictors of cardiac CTA image noise. Those parameters can be incorporated in standard CT protocols to adequately adjust radiation exposure.

    2016-01-01

    Cystic fibrosis has historically been considered a pulmonary disease, but with the increasing life expectancy of these patients, gastrointestinal manifestations are becoming more important. Furthermore, nutritional status is closely linked to pulmonary function and, thus, overall mortality. This article discusses gastrointestinal manifestations (which involve nutritional, pancreatic, hepatobiliary, and, in particular, gastrointestinal tract issues) of cystic fibrosis as well as management of the disease. In addition, the article discusses studies that have been critical to our understanding of gastrointestinal manifestations of cystic fibrosis. PMID:27330503

    Full Text Available OBJECTIVE - To evaluate the cardiac abnormalities and their evolution during the course of the acquired immunodeficiency syndrome, as well as to correlate clinical and pathological data. METHODS - Twenty-one patients, admitted to the hospital with the diagnosis of acquired immunodeficiency syndrome, were prospectively studied and followed until their death. Age ranged from 19 to 42 years (17 males. ECG and echocardiogram were also obtained every six months. After death, macro- and microscopic examinations were also performed. RESULTS - The most frequent causes of referral to the hospital were: diarrhea or repeated pneumonias, tuberculosis, toxoplasmosis or Kaposi sarcoma. The most frequent findings were acute or chronic pericarditis (42% and dilated cardiomyopathy (19%. Four patients died of cardiac problems: infective endocarditis, pericarditis with pericardial effusion, bacterial myocarditis and infection by Toxoplasma gondii. CONCLUSION - Severe cardiac abnormalities were the cause of death in some patients. In the majority of the patients, a good correlation existed between clinical and anatomical-pathological data. Cardiac evaluation was important to detect early manifestations and treat them accordingly, even in asymptomatic patients.

    To exploit the advantages of using rabbits for cardiac imaging research and to tackle the technical obstacles, efforts have been made under the framework of a doctoral research program. In this overview article, by cross-referencing the current literature, we summarize how we have developed a preclinical cardiac research platform based on modified models of reperfused myocardial infarction (MI) in rabbits; how the in vivo manifestations of cardiac imaging could be closely matched with those ex vivo macro- and microscopic findings; how these imaging outcomes could be quantitatively analyzed, validated and demonstrated; and how we could apply this cardiac imaging platform to provide possible solutions to certain lingering diagnostic and therapeutic problems in experimental cardiology. In particular, tissue components in acute cardiac ischemia have been stratified and characterized, post-infarct lipomatous metaplasia (LM) as a common but hardly illuminated clinical pathology has been identified in rabbit models, and a necrosis avid tracer as well as an anti-ischemic drug have been successfully assessed for their potential utilities in clinical cardiology. These outcomes may interest the researchers in the related fields and help strengthen translational research in cardiovascular diseases.

    The mite-borne rickettsial zoonosis scrub typhus is widely prevalent in parts of Southeast and Far East Asia, and northern Australia. The disease is an acute febrile illness, associated with rash and often an eschar, which responds dramatically to treatment with antibiotics. In some cases it results in a serious illness leading to multiple organ involvement and death. The disease manifestations are thought to result from a systemic vasculitis, caused by both direct effects of the organisms as well as an exaggerated immune response, although little is understood about its pathogenesis. A wide spectrum of clinical manifestations, affecting nearly every organ system, have been described with scrub typhus. Some of these manifestations are serious and life threatening. In this systematic review, we summarise the typical and atypical manifestations of scrub typhus reported in the literature. Awareness of these unusual manifestations will hopefully guide clinicians towards diagnosing the condition early, and initiating early appropriate antibiotics and other supportive measures. © The Author 2017.

    Full Text Available Cutaneous manifestations of human immunodeficiency virus (HIV disease may result from HIV infection itself, or from opportunistic disorders secondary to the declined immunocompetence due to the disease. A total of 220 HIV positive patients, treated in the Benghazi Center of Infectious Diseases and Immunology over a period of 14 years (January 2003 to November 2016, were included in a retrospective study. The patients' age ranged from 7 to 46 years. The study was conducted by reviewing the patients' records using the management information system (MIS. Statistical analysis of the data was carried out by the t-test and Chi square test. Among the studied patients, 119 (54.1% were males and 101 (45.9% were females, and most of them (78.6% were 10 – 19 years of age. The predominant mode of transmission was parenteral transmission, in 95% of patients, and positive family history was observed in 12% of patients. Among the total number of visits to dermatologists, 93% of patients had a single disease. Of the total number of skin diseases diagnosed during the visits, parasitic infestations were seen in 92 patients (21.0%, eczematous and related disorders in 78 patients (17.8%, viral infections in 71 patients (16.2%, bacterial infections in 41 patients (9.3%, and fungal infections in 35 patients (7.9%. Dermatophyte infections were the most common fungal infections recorded in 19 patients (4.3%, followed by Candida infection in 11 patients (2.5%. Warts were found in 5.9% of viral infections, followed by herpes zoster (4.1%. HIV positive patients should be examined for skin disorders, because early diagnosis and management of such problems improves the quality of life in these patients.

  6. Length dependence of force generation exhibit similarities between rat cardiac myocytes and skeletal muscle fibres.

    According to the Frank-Starling relationship, increased ventricular volume increases cardiac output, which helps match cardiac output to peripheral circulatory demand. The cellular basis for this relationship is in large part the myofilament length-tension relationship. Length-tension relationships in maximally calcium activated preparations are relatively shallow and similar between cardiac myocytes and skeletal muscle fibres. During twitch activations length-tension relationships become steeper in both cardiac and skeletal muscle; however, it remains unclear whether length dependence of tension differs between striated muscle cell types during submaximal activations. The purpose of this study was to compare sarcomere length-tension relationships and the sarcomere length dependence of force development between rat skinned left ventricular cardiac myocytes and fast-twitch and slow-twitch skeletal muscle fibres. Muscle cell preparations were calcium activated to yield 50% maximal force, after which isometric force and rate constants (k(tr)) of force development were measured over a range of sarcomere lengths. Myofilament length-tension relationships were considerably steeper in fast-twitch fibres compared to slow-twitch fibres. Interestingly, cardiac myocyte preparations exhibited two populations of length-tension relationships, one steeper than fast-twitch fibres and the other similar to slow-twitch fibres. Moreover, myocytes with shallow length-tension relationships were converted to steeper length-tension relationships by protein kinase A (PKA)-induced myofilament phosphorylation. Sarcomere length-k(tr) relationships were distinct between all three cell types and exhibited patterns markedly different from Ca(2+) activation-dependent k(tr) relationships. Overall, these findings indicate cardiac myocytes exhibit varied length-tension relationships and sarcomere length appears a dominant modulator of force development rates. Importantly, cardiac myocyte length

    Autonomic disorders have previously been described in association with the antiphospholipid syndrome. The present study aimed to determine the clinical phenotype of patients in whom autonomic dysfunction was the initial manifestation of the antiphospholipid syndrome and to evaluate for autonomic neuropathy in these patients. This was a retrospective study of 22 patients evaluated at the University of Colorado who were found to have a disorder of the autonomic nervous system as the initial manifestation of antiphospholipid syndrome. All patients had persistent antiphospholipid antibody positivity and all patients who underwent skin biopsy were found to have reduced sweat gland nerve fiber density suggestive of an autonomic neuropathy. All patients underwent an extensive evaluation to rule out other causes for their autonomic dysfunction. Patients presented with multiple different autonomic disorders, including postural tachycardia syndrome, gastrointestinal dysmotility, and complex regional pain syndrome. Despite most having low-titer IgM antiphospholipid antibodies, 13 of the 22 patients (59%) suffered one or more thrombotic event, but pregnancy morbidity was minimal. Prothrombin-associated antibodies were helpful in confirming the diagnosis of antiphospholipid syndrome. We conclude that autonomic neuropathy may occur in association with antiphospholipid antibodies and may be the initial manifestation of the syndrome. Increased awareness of this association is important, because it is associated with a significant thrombotic risk and a high degree of disability. In addition, anecdotal experience has suggested that antithrombotic therapy and intravenous immunoglobulin therapy may result in significant clinical improvement in these patients.

    There are several theoretic advantages to synchronizing positive pressure breaths with the cardiac cycle, including the potential for improving distribution of pulmonary and myocardial blood flow and enhancing cardiac output. The authors evaluated the effects of synchronizing respiration to the cardiac cycle using a programmable ventilator and electron beam CT (EBCT) scanning. The hearts of anesthetized dogs were imaged during cardiac gated respiration with a 50 msec scan aperture. Multi slice, short axis, dynamic image data sets spanning the apex to base of the left ventricle were evaluated to determine the volume of the left ventricular chamber at end-diastole and end-systole during apnea, systolic and diastolic cardiac gating. The authors observed an increase in cardiac output of up to 30% with inspiration gated to the systolic phase of the cardiac cycle in a non-failing model of the heart

Aesthetic and facial dysfunctions are followed by important oral and facial manifestations. Most oral manifestations begin with tongue rigidity and facial skin changes. Bone resorption of mandibular angle and widening of periodontal ligament space on periapical radiographs are important radiological findings. Other systemic changes include the involvement of internal organs, which lead to serious complications as well as disorders in the cardiac muscle and Raynaud΄s phenomenon. This is a case report of 30-year-old female patient with the classical features of this disease. This case is reported for its rarity and variable expressivity. The main aim of this article is to describe thorough presentation of the case report, various forms of scleroderma, pathogenesis, oral, extraoral, periodontal manifestations of scleroderma, and its treatment options. A brief review of the literature, focusing on dental alterations is also presented.

    Cognitive deficits have been reported in older cardiac patients. An underlying mechanism for these findings may be reduced cardiac function. The relationship between cardiac function as represented by different echocardiographic measures and different cognitive function domains in older cardiac patients remains unknown. An older (≥70 years) heterogeneous group of 117 community-dwelling cardiac patients under medical supervision by a cardiologist underwent thorough echocardiographic assessment including left ventricular ejection fraction, cardiac index, left atrial volume index, left ventricular mass index, left ventricular diastolic function, and valvular calcification. During a home visit, a neuropsychological assessment was performed within 7.1 ± 3.8 months after echocardiographic assessment; the neuropsychological assessment included three subtests of a word-learning test (encoding, recall, recognition) to examine one memory function domain and three executive function tests, including digit span backwards, Trail Making Test B minus A, and the Stroop colour-word test. Regression analyses showed no significant linear or quadratic associations between any of the echocardiographic functions and the cognitive function measures. None of the echocardiographic measures as representative of cardiac function was correlated with memory or executive function in this group of community-dwelling older cardiac patients. These findings contrast with those of previous studies. © 2017 Japanese Psychogeriatric Society.

    Cardiac interventional procedures have been increasing year by year. However, radiation skin injuries have been still reported. There is a necessity to measure the patient entrance skin dose (ESD), but an accurate dose measurement method has not been established. To measure the ESD, a lot of radiophotoluminescence dosemeters (RPLDs) provide an accurate measurement of the direct actual ESD at the points they are arrayed. The purpose of this study was to examine the characteristics of RPLD to measure the ESD. As a result, X-ray permeable RPLD (with no tin filter) did not interfere with the percutaneous coronary intervention procedure. The RPLD also had good fundamental performance characteristics. Although the RPLD had a little energy dependence, it showed excellent dose and dose-rate linearity, and good angular dependence. In conclusion, by calibrating the energy dependence, RPLDs are useful dosemeter to measure the ESD in cardiac intervention. (authors)

    Skin permeability is widely considered to be mechanistically implicated in chemically-induced skin sensitization. Although many chemicals have been identified as skin sensitizers, there have been very few reports analyzing the relationships between molecular structure and skin permeability of sensitizers and non-sensitizers. The goals of this study were to: (i) compile, curate, and integrate the largest publicly available dataset of chemicals studied for their skin permeability; (ii) develop and rigorously validate QSAR models to predict skin permeability; and (iii) explore the complex relationships between skin sensitization and skin permeability. Based on the largest publicly available dataset compiled in this study, we found no overall correlation between skin permeability and skin sensitization. In addition, cross-species correlation coefficient between human and rodent permeability data was found to be as low as R{sup 2} = 0.44. Human skin permeability models based on the random forest method have been developed and validated using OECD-compliant QSAR modeling workflow. Their external accuracy was high (Q{sup 2}{sub ext} = 0.73 for 63% of external compounds inside the applicability domain). The extended analysis using both experimentally-measured and QSAR-imputed data still confirmed the absence of any overall concordance between skin permeability and skin sensitization. This observation suggests that chemical modifications that affect skin permeability should not be presumed a priori to modulate the sensitization potential of chemicals. The models reported herein as well as those developed in the companion paper on skin sensitization suggest that it may be possible to rationally design compounds with the desired high skin permeability but low sensitization potential. - Highlights: • It was compiled the largest publicly-available skin permeability dataset. • Predictive QSAR models were developed for skin permeability. • No concordance between skin

    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.

    A middle aged male presented with non-tender cystic swelling over left distal forearm since 1 year. No other cutaneous abnormality could be found except mild paresthesia of the overlying skin and equivocal thickening of the ipsilateral ulnar nerve. Routine investigation was within normal limits. Detailed workup of the patient including MRI of the lesion suggested the diagnosis as tenosynovitis with a soft tissue mass. Fine needle aspiration cytology from the cyst showed foamy macrophages and acid fast bacilli; while PCR of the aspirate confirmed the etiological agent as M. leprae. We, thus, report a unique case of isolated tenosynovitis as a sole manifestation of pure neural leprosy which is extremely rare in world literature. PMID:25814736

    Infants and children are a higher risk population for radiation cancer induction compared to adults. Although some values on pediatric patient doses for cardiac procedures have been reported, data to determine reference levels are scarce, especially when compared to those available for adults in diagnostic and therapeutic procedures. The aim of this study is to make a new contribution to the scarce published data in pediatric cardiac procedures and help in the determination of future dose reference levels. This paper presents a set of patient dose values, in terms of air kerma area product (KAP) and entrance surface air kerma (ESAK), measured in a pediatric cardiac catheterization laboratory equipped with a biplane x-ray system with dynamic flat panel detectors. Cardiologists were properly trained in radiation protection. The study includes 137 patients aged between 10 days and 16 years who underwent diagnostic catheterizations or therapeutic procedures. Demographic data and technical details of the procedures were also gathered. The x-ray system was submitted to a quality control programme, including the calibration of the transmission ionization chamber. The age distribution of the patients was 47 for <1 year; 52 for 1-<5 years; 25 for 5-<10 years and 13 for 10-<16 years. Median values of KAP were 1.9, 2.9, 4.5 and 15.4 Gy cm2 respectively for the four age bands. These KAP values increase by a factor of 8 when moving through the four age bands. The probability of a fatal cancer per fluoroscopically guided cardiac procedure is about 0.07%. Median values of ESAK for the four age bands were 46, 50, 56 and 163 mGy, which lie far below the threshold for deterministic effects on the skin. These dose values are lower than those published in previous papers.

    Psoriasis is a systemic disease with cutaneous manifestations. MicroRNAs (miRNAs) are small non-coding RNA molecules that are differentially expressed in psoriatic skin; however, only few cell- and region-specific miRNAs have been identified in psoriatic lesions. We used laser capture...... microdissection (LCM) and next-generation sequencing (NGS) to study the specific miRNA expression profiles in the epidermis (Epi) and dermal inflammatory infiltrates (RD) of psoriatic skin (N = 6). We identified 24 deregulated miRNAs in the Epi and 37 deregulated miRNAs in the RD of psoriatic plaque compared...... with normal psoriatic skin (FCH > 2, FDR

    Numerous genetic syndromes associated with heart disease and ocular manifestations have been described. However, a compilation and a summarization of these syndromes for better consultation and comparison have not been performed yet. The objective of this work is to systematize available evidence in the literature on different syndromes that may cause congenital heart diseases associated with ocular changes, focusing on the types of anatomical and functional changes. A systematic search was performed on Medline electronic databases (PubMed, Embase, Cochrane, Lilacs) of articles published until January 2016. Eligibility criteria were case reports or review articles that evaluated the association of ophthalmic and cardiac abnormalities in genetic syndrome patients younger than 18 years. The most frequent genetic syndromes were: Down Syndrome, Velo-cardio-facial / DiGeorge Syndrome, Charge Syndrome and Noonan Syndrome. The most associated cardiac malformations with ocular findings were interatrial communication (77.4%), interventricular communication (51.6%), patent ductus arteriosus (35.4%), pulmonary artery stenosis (25.8%) and tetralogy of Fallot (22.5%). Due to their clinical variability, congenital cardiac malformations may progress asymptomatically to heart defects associated with high morbidity and mortality. For this reason, the identification of extra-cardiac characteristics that may somehow contribute to the diagnosis of the disease or reveal its severity is of great relevance.

    Alkaptonuria is a rare autosomal recessive metabolic disorder that may present with multi-system involvement such as ochronotic arthropathy, renal, urethral and prostatic calculi, cardiac valvular lesions and pigmentation of the skin, sclera, cartilage and other connective tissues. An association of the disease with uveitis has never been reported. We report the first case of alkaptonuria with ochronotic arthropathy presenting with recurrent acute anterior uveitis as the initial manifestation. The possible common link with the HLA-B27 gene is discussed.

    There currently is a limited ability to interactively study developmental cardiac mechanics and physiology. We therefore combined light-sheet fluorescence microscopy (LSFM) with virtual reality (VR) to provide a hybrid platform for 3- dimensional (3-D) architecture and time-dependent cardiac contractile function characterization. By taking advantage of the rapid acquisition, high axial resolution, low phototoxicity, and high fidelity in 3-D and 4-D (3-D spatial + 1-D time or spectra), this VR-LSFM hybrid methodology enables interactive visualization and quantification otherwise not available by conventional methods such as routine optical microscopes. We hereby demonstrate multi-scale applicability of VR-LSFM to 1) interrogate skin fibroblasts interacting with a hyaluronic acid-based hydrogel, 2) navigate through the endocardial trabecular network during zebrafish development, and 3) localize gene therapy-mediated potassium channel expression in adult murine hearts. We further combined our batch intensity normalized segmentation (BINS) algorithm with deformable image registration (DIR) to interface a VR environment for the analysis of cardiac contraction. Thus, the VR-LSFM hybrid platform demonstrates an efficient and robust framework for creating a user-directed microenvironment in which we uncovered developmental cardiac mechanics and physiology with high spatiotemporal resolution.

    Complex percutaneous interventions often require high radiation doses likely to produce skin radiation injuries. We assessed the methodology used to select patients with potential skin injuries in cardiac procedures and in need of clinical follow-up. We evaluated peak skin dose and clinical follow-up in a case of radiodermatitis produced during a total occlusion recanalization. This prospective study followed CIRSE and ACC/AHA/SCAI recommendations for patient radiation dose management in interventional procedures carried out in a university hospital with a workload of 4200 interventional cardiac procedures per year. Patient dose reports were automatically transferred to a central database. Patients exceeding trigger levels for air kerma area product (500 Gy cm{sup 2}) and cumulative skin dose (5 Gy) were counseled and underwent follow-up for early detection of skin injuries, with dermatologic support. The Ethical Committee and the Quality Assurance and Radiation Safety Committee approved the program. During 2010, a total of 13 patients (3.0/1,000 that year) received dose values exceeding trigger levels in the cardiovascular institute. Only one patient, who had undergone two consecutive procedures resulting in 970 Gy cm{sup 2} and 13.0 Gy as cumulative skin dose, showed signs of serious radiodermatitis that resolved in 3.7 months. The remaining patients did not manifest skin lesions during follow-up, and whenever patient examination was not feasible as part of the follow-up, neither patients nor families reported any skin injuries. Peak skin dose calculation and close clinical follow-up were feasible and appropriate, with a moderate additional workload for the staff and satisfaction for the patient.

Specific dermatoses are markers for undiagnosed DM. Other disorders represent supervening complications in an already treated DM patient. Objective: To review the information about dermocosmetic care products and their appropriate use in the management and prevention of dermatoses related to DM. Method: The peer-reviewed literature and empiric findings are covered. Owing to the limited clinical evidence available for the use of dermocosmetics, a review of the routine practices and common therapies in DM-related dermatoses was conducted. Results: Some DM-related dermatoses (acanthosis nigricans, pigmented purpuric dermatosis are markers of macrovascular complications. The same disorders and some others (xerosis, Dupuytren's disease have been found to be more frequently associated with microangiopathy. Other skin diseases (alopecia areata, vitiligo were found to be markers of autoimmunity, particularly in type 1 DM. Unsurprisingly, using dermocosmetics and appropriate skin care has shown objective improvements of some DM-related dermatoses, such effects improve the quality of life. The most common skin manifestations of DM fall along continuum between "dry skin," xerosis, and acquired ichthyosis, occurring predominately on the shins and feet.

    Hypochrondroplasia is an inherited skeletal dysplasia that resembles achondroplasia in mild degree. Radiographic manifestations encountered in 12 affected individuals in South Africa include slight shortening of all segments of the tubular bones, moderate caudal diminution of the lumbar interpedicular distances, increased lumbar lordosis with cacral tilt and distal prolongation of the fibular. Hypochondroplasia can be distinguished from other osteochondrodystrophies such as achondroplasia, pseudo-achondroplasia and metaphyseal chondroplasia by the recognition of it clinical and radiographic manifestations.

    Although trichotillomania (TTM), skin picking (SP), and nail biting (NB) have been receiving growing scientific attention, the question as to whether these disorders can be regarded as separate entities or they are different manifestations of the same underlying tendency is unclear. Data were collected online in a community survey, yielding a sample of 2705 participants (66% women, mean age: 29.1, SD: 8.6). Hierarchical factor analysis was used to identify a common latent factor and the multiple indicators and multiple causes (MIMIC) modelling was applied to test the predictive effect of borderline personality disorder symptoms, impulsivity, distress and self-esteem on pathological grooming. Pearson correlation coefficients between TTM, SP and NB were between 0.13 and 0.29 (p grooming factor. Impulsivity, psychiatric distress and contingent self-esteem had significant predictive effects, whereas borderline personality disorder had a nonsignificant predictive effect on the latent factor. We found evidence that the category of pathological grooming is meaningful and encompasses three symptom manifestations: trichotillomania, skin picking and nail biting. This latent underlying factor is not better explained by indicators of psychopathology, which supports the notion that the urge to self-groom, rather than general psychiatric distress, impulsivity, self-esteem or borderline symptomatology, is what drives individual grooming behaviours.

    Rosai-Dorfman Disease (RDD), also known as Sinus Histiocytosis with Massive Lymphadenopathy (SHML), is a rare monocyte/macrophage proliferative disorder of varied biological behavior. Although cutaneous and lymph node involvement are relatively well-described, intrathoracic manifestations of RDD have only occasionally been reported. We conducted a retrospective computer-assisted search of the Mayo Clinic record from 1976 to 2005 for patients with histopathologic evidence of RDD on organ biopsy. Clinical characteristics were abstracted from charts and thoracic manifestations recorded. Survival was estimated using the national social security database. A total of 21 patients were diagnosed with RDD over a period of 30 years; 9 had intrathoracic manifestations (43%). Main pulmonary symptoms included dyspnea and cough. Age at the time of diagnosis, gender, race, smoking history, mortality and time of survival after diagnosis were no different between RDD patients with and without intrathoracic manifestations. The most common radiographic thoracic manifestation was mediastinal lymphadenopathy (6 patients). Cystic change, interstitial lung disease, and airway disease were radiographically evident in 4 patients. Seven patients were treated at some point in the course of their disease, most commonly with oral corticosteroids. At the time of last follow-up 87% were alive, with a median (IQR) time interval since diagnosis of 8 years (4-9.7). Intrathoracic manifestations of RDD are relatively common and include mediastinal lymphadenopathy, airway disease, pleural effusion, cystic and interstitial lung disease. Although limited in size, this series suggests the prognosis of patients with RDD and intrathoracic manifestations is relatively good.

    Cardiac function was measured by radionuclide cardiac blood-pool imaging in 15 normal persons, 19 cases of hypertension, 32 cases of coronary heart disease, 35 cases of coronary heart disease combined with hypertension and 44 cases of myocardial infarction. Significant differences have been found in indices of cardiac function between normal subjects and patients with coronary heart disease and coronary heart disease combined with hypertension, even though the patients were without any clinical sin of cardiac failure. Lowered regional EF and decreased ventricular was motion were found in 38.8% of patients, while 65.7%of patients revealed marked abnormality in MFR. The results indicate that latent cardiac dysfunction is common in patients with coronary heart disease. The earliest change is diastolic function abnormalities

    Full Text Available Background. Infection with Coxsackievirus B3 induces myocarditis. We aimed to compare the acute and chronic phases of viral myocarditis to identify the immediate effects of cardiac inflammation as well as the long-term effects after resolved inflammation on cardiac fibrosis and consequently on cardiac function. Material and Methods. We infected C57BL/6J mice with Coxsackievirus B3 and determined the hemodynamic function 7 as well as 28 days after infection. Subsequently, we analyzed viral burden and viral replication in the cardiac tissue as well as the expression of cytokines and matrix proteins. Furthermore, cardiac fibroblasts were infected with virus to investigate if viral infection alone induces profibrotic signaling. Results. Severe cardiac inflammation was determined and cardiac fibrosis was consistently colocalized with inflammation during the acute phase of myocarditis. Declined cardiac inflammation but no significantly improved hemodynamic function was observed 28 days after infection. Interestingly, cardiac fibrosis declined to basal levels as well. Both cardiac inflammation and fibrosis were reversible, whereas the hemodynamic function remains impaired after healed viral myocarditis in C57BL/6J mice.

    Purpose: The aim of this study was to assess the incidence of cardiac and significant extra-cardiac findings in clinical computed tomography of the heart in patients with atrial fibrillation before pulmonary vein isolation (PVI). Materials and Methods: 224 patients (64 ± 10 years; male 63%) with atrial fibrillation were examined by cardiac 64-slice multidetector CT before PVI. Extra-cardiac findings were classified as 'significant' if they were recommended to additional diagnostics or therapy, and otherwise as 'non-significant'. Additionally, cardiac findings were documented in detail. Results: A total of 724 cardiac findings were identified in 203 patients (91% of patients). Additionally, a total of 619 extra-cardiac findings were identified in 179 patients (80% of patients). Among these extra-cardiac findings 196 (32%) were 'significant', and 423 (68%) were 'non-significant'. In 2 patients (1%) a previously unknown malignancy was detected (esophageal cancer and lung cancer, local stage, no metastasis). 203 additional imaging diagnostics followed to clarify the 'significant' findings (124 additional CT, costs 38,314.69 US dollars). Overall, there were 3.2 cardiac and 2.8 extra-cardiac findings per patient. Extra-cardiac findings appear significantly more frequently in patients over 60 years old, in smokers and in patients with a history of cardiac findings (p < 0.05). Conclusion: Cardiac CT scans before PVI should be screened for extracardiac incidental findings that could have important clinical implications for each patient. (orig.)

    Skin permeability is widely considered to be mechanistically implicated in chemically-induced skin sensitization. Although many chemicals have been identified as skin sensitizers, there have been very few reports analyzing the relationships between molecular structure and skin permeability of sensitizers and non-sensitizers. The goals of this study were to: (i) compile, curate, and integrate the largest publicly available dataset of chemicals studied for their skin permeability; (ii) develop and rigorously validate QSAR models to predict skin permeability; and (iii) explore the complex relationships between skin sensitization and skin permeability. Based on the largest publicly available dataset compiled in this study, we found no overall correlation between skin permeability and skin sensitization. In addition, cross-species correlation coefficient between human and rodent permeability data was found to be as low as R2=0.44. Human skin permeability models based on the random forest method have been developed and validated using OECD-compliant QSAR modeling workflow. Their external accuracy was high (Q2ext = 0.73 for 63% of external compounds inside the applicability domain). The extended analysis using both experimentally-measured and QSAR-imputed data still confirmed the absence of any overall concordance between skin permeability and skin sensitization. This observation suggests that chemical modifications that affect skin permeability should not be presumed a priori to modulate the sensitization potential of chemicals. The models reported herein as well as those developed in the companion paper on skin sensitization suggest that it may be possible to rationally design compounds with the desired high skin permeability but low sensitization potential.

    Full Text Available The aim of this study was to analyze the characteristics and clinical manifestations of secondary syphilis among patients registered at the City Institute for Skin and Venereal Diseases in Belgrade, during the period from 2010 to 2014. The study was designed as a case-note review. In the five-year period, a total of 62 patients with secondary syphilis were registered. The average patient age was 32 years. There were 45 (72.6% HIV-negative, and 17 (27.4% HIV-positive patients. The incidence of HIV–positive patients was significantly different from random distribution (p = 0.016. All HIV-positive patients were unmarried men. A significant percentage of HIV-positive patients were unemployed (p < 0.001, reported unknown source of infection (p = 0.002 and were all homosexuall (p = 0.026. More than 25% of all patients with syphilis had a history of chancres, and it was still present at the time of examination in 11.3% of all patients. The majority of cases (87.1% had a rash, and lymphadenopathy was found in 20% of patients. However, syphilitic alopecia was detected only in HIV-positive cases (p = 0.004. There were no statistically significant differences between HIV-positive and HIV-negative patients in regard to other clinical manifestations, such as mucous patches and condylomata lata. Being a great imitator, secondary syphilis may manifest in a myriad of diverse morphological entities and clinical manifestations. We review a range of cutaneous manifestations of secondary syphilis and skin diseases it may mimic. Clinicians must be vigilant and consider syphilis in differential diagnosis, and maintain a high index of suspicion, especially when assessing vulnerable populations, such as men who have sex with men and HIV-infected individuals.

    Biological effect of a visible light depends on extend of its property to penetrate into the tissues: the greater is a wavelength the more is an effect of a radiation. An impact of a visible light on the skin is evident by wave and quantum effects. Quanta of a visible radiation carry more energy than infrared radiation, although an influence of such radiation on the skin is produced by the light spectrum on the boarder of the ultraviolet and the infrared rays and is manifested by thermal and chemical effects. It is determined that large doses of a visible light (405-436 nm) can cause skin erythema. At this time, the ratio of generation of free radicals in the skin during an exposure to the ultraviolet and the visible light range from 67-33% respectively. Visible rays of 400-500 nm length of wave cause an increase of the concentration of oxygen's active form and mutation of DNA and proteins in the skin. The urticaria in 4-18% of young people induced by photodermatosis is described. As a result of a direct exposure to sunlight photosensitive eczema is more common in elderly. Special place holds a hereditary disease - porphyria, caused by a visible light. In recent years, dermatologists widely use phototherapy. The method uses polychromatic, non-coherent (wavelength of 515-1200 nm) pulsating beam. During phototherapy/light treatment a patient is being exposed to sunlight or bright artificial light. Sources of visible light are lasers, LEDs and fluorescent lamps which have the full range of a visible light. Phototherapy is used in the treatment of acne vulgaris, seasonal affective disorders, depression, psoriasis, eczema and neurodermities. LED of the red and near infrared range also is characterized by the therapeutic effect. They have an ability to influence cromatophores and enhance ATP synthesis in mitochondria. To speed up the healing of wounds and stimulate hair growth light sources of a weak intensity are used. The light of blue-green spectrum is widely used for

    Cardiac interventional procedures have been increasing year by year. However, radiation skin injuries have been still reported. There is a necessity to measure the patient entrance skin dose (ESD), but an accurate dose measurement method has not been established. To measure the ESD, a lot of radiophotoluminescence dosemeters (RPLDs) provide an accurate measurement of the direct actual ESD at the points they are arrayed. The purpose of this study was to examine the characteristics of RPLD to measure the ESD. As a result, X-ray permeable RPLD (with no tin filter) did not interfere with the percutaneous coronary intervention procedure. The RPLD also had good fundamental performance characteristics. Although the RPLD had a little energy dependence, it showed excellent dose and dose-rate linearity, and good angular dependence. In conclusion, by calibrating the energy dependence, RPLDs are useful dosemeter to measure the ESD in cardiac intervention. © The Author 2013. Published by Oxford University Press.

    Full Text Available Philip D Shenefelt,1 Debrah A Shenefelt2 1Dermatology and Cutaneous Surgery, University of South Florida, Tampa, 2Congregation Or Ahavah, Lutz, FL, USA Abstract: Skin and skin disorders have had spiritual aspects since ancient times. Skin, hair, and nails are visible to self and others, and touchable by self and others. The skin is a major sensory organ. Skin also expresses emotions detectable by others through pallor, coldness, "goose bumps", redness, warmth, or sweating. Spiritual and religious significances of skin are revealed through how much of the skin has been and continues to be covered with what types of coverings, scalp and beard hair cutting, shaving and styling, skin, nail, and hair coloring and decorating, tattooing, and intentional scarring of skin. Persons with visible skin disorders have often been stigmatized or even treated as outcasts. Shamans and other spiritual and religious healers have brought about healing of skin disorders through spiritual means. Spiritual and religious interactions with various skin disorders such as psoriasis, leprosy, and vitiligo are discussed. Religious aspects of skin and skin diseases are evaluated for several major religions, with a special focus on Judaism, both conventional and kabbalistic.

    Henoch-Schönlein purpura is a relatively common vasculitis mainly affecting children. It is characterized by purpuric skin rash, abdominal cramping, and haematuria. Skin biopsies taken from Henoch-Schönlein purpura lesions disclose perivascular IgA deposits. FMF is an autoinflammatory disease characterized by recurrent attacks of fever lasting 2-3 days which resolve spontaneously. Typical manifestations of the disease are peritonitis, pleuritis, pericarditis, arthritis and erysipelas-like erythema usually affecting the lower limbs. Over the years many reviews emphasized the clinical impression that Henoch-Schönlein purpura is more common among FMF patients than in healthy control population. In this review we summarize these reports and show that sometimes Henoch-Schönlein purpura associated with FMF differs from typical isolated Henoch-Schönlein purpura, and this is also the case with polyarteritis nodosa and SpA associated with FMF. It is suggested that these clinical manifestations (polyarteritis nodosa, Henoch-Schönlein purpura and SpA) should be considered to be associated with FMF as part of what we call FMF rather than as co-existing additional separate clinical entities. © The Author 2015.

    Background Multicenter data regarding cardiac arrest in children undergoing heart operations are limited. We describe epidemiology and outcomes associated with postoperative cardiac arrest in a large multiinstitutional cohort. Methods Patients younger than 18 years in the Society of Thoracic Surgeons Congenital Heart Surgery Database (2007 through 2012) were included. Patient factors, operative characteristics, and outcomes were described for patients with and without postoperative cardiac arrest. Multivariable models were used to evaluate the association of center volume with cardiac arrest rate and mortality after cardiac arrest, adjusting for patient and procedural factors. Results Of 70,270 patients (97 centers), 1,843 (2.6%) had postoperative cardiac arrest. Younger age, lower weight, and presence of preoperative morbidities (all p < 0.0001) were associated with cardiac arrest. Arrest rate increased with procedural complexity across common benchmark operations, ranging from 0.7% (ventricular septal defect repair) to 12.7% (Norwood operation). Cardiac arrest was associated with significant mortality risk across procedures, ranging from 15.4% to 62.3% (all p < 0.0001). In multivariable analysis, arrest rate was not associated with center volume (odds ratio, 1.06; 95% confidence interval, 0.71 to 1.57 in low- versus high-volume centers). However, mortality after cardiac arrest was higher in low-volume centers (odds ratio, 2.00; 95% confidence interval, 1.52 to 2.63). This association was present for both high- and low-complexity operations. Conclusions Cardiac arrest carries a significant mortality risk across the stratum of procedural complexity. Although arrest rates are not associated with center volume, lower-volume centers have increased mortality after cardiac arrest. Further study of mechanisms to prevent cardiac arrest and to reduce mortality in those with an arrest is warranted. PMID:25443018

    E-1020 is a cardiotonic agent that acts as a cyclic-AMP phosphodiesterase inhibitor but also may have actions which alter myofilament response to Ca2+. To identify direct actions of E-1020 on cardiac contractile proteins, effects of E-1020 on myofibrillar Ca2+ dependent MgATPase and force generation in chemically skinned fiber bundles were measured. In bovine cardiac myofibrils, E-1020 (100 microM) significantly increased myofilament Ca2+ sensitivity and Ca(2+)-dependent ATPase activity at submaximal pCa values. At pCa 6.75, E-1020 significantly increased ATPase activity in bovine (10-100 microM) and canine (1-100 microM) cardiac myofibrils but had no effect on rat cardiac myofibrils. Moreover, in one population of canine ventricular fiber bundles, E-1020 (0.01-10 microM) significantly increased isometric tension at pCa 6.5 and 6.0, whereas in another population of bundles E-1020 had no effect on tension. In no case was resting (pCa 8.0) or maximal tension (pCa 4.5) increased by E-1020. Measurements of Ca2+ binding to canine ventricular skinned fiber preparations demonstrated that E-1020 does not alter the affinity of myofilament troponin C for Ca2+. We conclude that part of the mechanism by which E-1020 acts as an inotropic agent may involve alterations in the responsiveness of contractile proteins to Ca2+. The lack of effect of E-1020 on some preparations may be dependent on isoform populations of myofilament proteins.

    Acute fish liver intoxication, including hypervitaminosis A and hypervitaminosis D, may result from the ingestion of certain fish livers. The typical symptoms of hypervitaminosis A include nausea, headache, blurred vision, and cutaneous manifestations, such as flushing, vesicles formation, and desquamation. Hypervitaminosis D may result in hypercalcemia. We report a case of acute fish liver intoxication with systemic and cutaneous manifestations. A 63-year-old male presented to the clinic with generalized desquamation and multiple clear-fluid filled flaccid vesicles after eating approximately two fist-sized portions (about 300-400 g) of cooked seerfish (Scomberomorus spp.) liver. Laboratory examination showed a high serum level of vitamin A and D, and hypercalcemia. Fish liver consumption from particular fish may result in acute hypervitaminosis A and D. In patients with skin detachment or blister formation, headache, drowsiness, and other symptoms and signs consistent with hypervitaminosis A and/or hypercalcemia, a history of fish intake should be sought, and a serum level of vitamin A and D should be measured.

    Full Text Available Background: Plant-origin foods are among the most important sources of food allergic reactions. An increase in the incidence of sesame seed allergy among children and adults has been reported in recent years. The aim of this preliminary study was to investigate the prevalence, importance and clinical manifestations of sesame allergy among Iranian patients.Methods: In a cross-sectional survey, 250 patients with suspected IgE-mediated food allergies completed a questionnaire and underwent skin prick tests with sesame extract as well as cross-reacting foods (walnut, soya and peanut. Total IgE and sesame-specific IgE levels were measured. Patients with positive skin test reactions and/or IgE specific for sesame without clinical symptoms were considered sensitive to sesame. The patients who also had clinical symptoms with sesame consumption were diagnosed as allergic to sesame.Results: Of the 250 patients enrolled in this study, 129 were male and 121 female, with a mean age of 11.7 years. The most common food allergens were cow's milk, egg, curry, tomato and sesame. Sesame sensitivity was found in 35 patients (14.1%. Only five patients (2% had sesame allergy. Sesame-sensitive patients had a significantly higher frequency of positive prick test to cross-reacting foods when compared to non-sensitized patients (p=0.00. The type of symptom was independent of gender and age of the patients, but urticaria and dermatitis-eczema were significantly more frequent in sensitized patients (p=0.008.Conclusions: This is the first study addressing the prevalence of sesame seed allergy in Iranian population. We found sesame to be a common and important cause of food allergy. The panel of foods recommended for use in diagnostic allergy tests should be adjusted.

  7. Stimulating endogenous cardiac regeneration

    Full Text Available The healthy adult heart has a low turnover of cardiac myocytes. The renewal capacity, however, is augmented after cardiac injury. Participants in cardiac regeneration include cardiac myocytes themselves, cardiac progenitor cells, and peripheral stem cells, particularly from the bone marrow compartment. Cardiac progenitor cells and bone marrow stem cells are augmented after cardiac injury, migrate to the myocardium, and support regeneration. Depletion studies of these populations have demonstrated their necessary role in cardiac repair. However, the potential of these cells to completely regenerate the heart is limited. Efforts are now being focused on ways to augment these natural pathways to improve cardiac healing, primarily after ischemic injury but in other cardiac pathologies as well. Cell and gene therapy or pharmacological interventions are proposed mechanisms. Cell therapy has demonstrated modest results and has passed into clinical trials. However, the beneficial effects of cell therapy have primarily been their ability to produce paracrine effects on the cardiac tissue and recruit endogenous stem cell populations as opposed to direct cardiac regeneration. Gene therapy efforts have focused on prolonging or reactivating natural signaling pathways. Positive results have been demonstrated to activate the endogenous stem cell populations and are currently being tested in clinical trials. A potential new avenue may be to refine pharmacological treatments that are currently in place in the clinic. Evidence is mounting that drugs such as statins or beta blockers may alter endogenous stem cell activity. Understanding the effects of these drugs on stem cell repair while keeping in mind their primary function may strike a balance in myocardial healing. To maximize endogenous cardiac regeneration,a combination of these approaches couldameliorate the overall repair process to incorporate the participation ofmultiple cell players.

    2014-12-01

    Full Text Available Background Coronary heart disease (CHD is a major health concern, affecting nearly half the middle-age population and responsible for nearly one-third of all deaths. Clinicians have several major responsibilities beyond diagnosing CHD, such as risk stratification of patients for major adverse cardiac events (MACE and treating risks, as well as the patient. This second of a two-part review series discusses treating risk factors, including autonomic dysfunction, and expected outcomes. Methods Therapies for treating cardiac mortality risks including cardiovascular autonomic neuropathy (CAN, are discussed. Results While risk factors effectively target high-risk patients, a large number of individuals who will develop complications from heart disease are not identified by current scoring systems. Many patients with heart conditions, who appear to be well-managed by traditional therapies, experience MACE. Parasympathetic and Sympathetic (P&S function testing provides more information and has the potential to further aid doctors in individualizing and titrating therapy to minimize risk. Advanced autonomic dysfunction (AAD and its more severe form cardiovascular autonomic neuropathy have been strongly associated with an elevated risk of cardiac mortality and are diagnosable through autonomic testing. This additional information includes patient-specific physiologic measures, such as sympathovagal balance (SB. Studies have shown that establishing and maintaining proper SB minimizes morbidity and mortality risk. Conclusions P&S testing promotes primary prevention, treating subclinical disease states, as well as secondary prevention, thereby improving patient outcomes through (1 maintaining wellness, (2 preventing symptoms and disorder and (3 treating subclinical manifestations (autonomic dysfunction, as well as (4 disease and symptoms (autonomic neuropathy.

    Rosacea - a widespread disease sometimes aleak with severe complications, mainly affecting the skin. Irrational and inadequate treatment leads to chronicity of diseases and psychosocial disadaptation of patients. Lately, a clear upward trend in the number of patients in whom in the process of complex treatment manifestations (with the varying degrees of severity) of impaired barrier function of the skin are observed and they need the protection and restoration of the damaged stratum corneum. In patients with rosacea in order to study the function of the facial skin's horny layer we used the skin analyzer BIA (bioimpedance analysis, which in duration of 6 seconds determines the moisture content, oiliness and the softness of the skin) and significant deviations from the norm (decrease in moisture content, fatness and increased roughness) was revealed. These changes were most clearly pronounced in patients with steroid rosacea. To restore the skin barrier the drug "Episofit A" (Laboratory of Evolutionary Dermatology, France) has been used (1-2 times a day for 6 weeks). Evaluation of treatment efficacy was conducted every 2 weeks by means of a scale from 0 to 5 for parameters of dryness, erythema, peeling and expression of subjective feelings. In accordance with received results, using of Episofit A emulsion, especially on the baсkground of long-term treatment with topical steroids, had a pronounced therapeutic effect. Thus, treatment of patients with consideration of morphological and functional features of facial skin, helps to improve the results traditional therapy, and the drug is highly effective means of the new direction in skin care - corneotherapy aimed to reconstruct and protect damaged stratum corneum.

    Portal hypertension has a broad differential diagnosis. POEMS syndrome is an uncommon cause of it. POEMS syndrome is a rare disease involving multiple organs. In differential diagnosis of portal hypertension, POEMS syndrome should be considered especially when other symptoms such as numbness, organomegaly, endocrine alteration and skin changes also present, as it is highlighted by our case. We report a 46-year-old Chinese male, a teacher, presenting with portal hypertension. Electromyography revealed peripheral neuropathy. Immunofixation showed monoclonal immunoglobulin A lambda protein. The diagnosis of POEMS syndrome was established. After treatment of lenalidomide combined with dexamethasone over 2 years, the patient achieved a considerable improvement. This case highlights the manifestation of portal hypertension in POEMS syndrome. Lenalidomide with or without dexamethasone is effective for portal hypertension due to POEMS syndrome, though esophageal and gastric varices seems not reversible so easily.

    Ulcerative colitis (UC) is a chronic disease clinically manifest either by bowel symptoms alone or extraintestinal symptoms. Our prospective study included 635 patients with ulcerative colitis (334 males and 301 females, mean age 37.54 +/- 13.84, range 20-70 years). The presence of the common extraintestinal symptoms (ES) was analyzed. Of the 635 investigated patients, these symptoms were found in 83 (13%, 49 males and 34 females, mean age 41.6 +/- 13.95 range 21-70). Patients with ES suffered longer from UC on the average, that is 60.6 years. Most commonly ES involved the joints, 38 (45.8%) patients, hepatobiliary, 28 patients (33.7%), skin, 10 patients (12%) and eyes, 7 patients (8.4%). In 18% of the patients two or more ES were present. ES were clinically detectable after the intestinal symptoms in 81% patients. An increased tendency of ES to occur in patients with a more extensive disease was noticed. The prevalence of ES in the UC patients from NE Romania is in agreement with data from other countries. The number of ES supports the need for complex follow-up in these patients.

    Full Text Available Leptospirosis has a spectrum of presentation which ranges from mild disease to a severe form comprising of jaundice and renal failure. Involvement of the lung can vary from subtle clinical features to deadly pulmonary hemorrhage and acute respiratory distress syndrome. Of late, it has been identified that leptospirosis can present atypically with predominant pulmonary manifestations. This can delay diagnosis making and hence optimum treatment. The purpose of this review is to bring together all the reported pulmonary manifestations of leptospirosis and the recent trends in the management.

  13. Thermodynamics in 'Manifest Reality'

    International Nuclear Information System (INIS)

    2010-01-01

    D'Espagnat's proof that the universe is not a 'strongly objective reality' demands that all physical processes are reconsidered in that light. D'Espagnat suggests a 'Veiled Reality' as a suitable alternative. The most economical way to achieve that is to demand that 'information production' at a quantum level creates the basis for self-consistent perception of a world of macroscopic, 'manifest' entities, as opposed to self-existent objects. Such a 'manifest reality' fulfils both Wheeler's attempt at an 'IT-from-BIT' programme, and Zeilinger's suggestion that 'information is primary'.

    Objective: To investigate the risk factors, clinical features, treatments, and prevention of pulmonary hypertensive crisis (PHC) in children with idiopathic pulmonary arterial hypertension (IPAH) undergoing cardiac catheterization. Methods: This retrospective study included 67 children who were diagnosed with IPAH and underwent cardiac catheterization between April 2009 and June 2017 in Beijing Anzhen Hospital. The medical histories, clinical manifestations, treatments, and outcomes were characterized. Statistical analyses were performed using t test, χ(2) test and a multiple Logistic regression analysis. Results: During cardiac catheterization, five children developed PHC who presented with markedly elevated pulmonary artery pressure and central venous pressure, decline in systemic arterial pressure and oxygen saturation. Heart rate decreased in 4 cases and increased in the remaining one. After the treatments including cardiopulmonary resuscitation, pulmonary vasodilator therapy, improving cardiac output and blood pressure, and correction of acidosis, 4 of the 5 cases recovered, while 1 died of severe right heart failure with irreversible PHC 3 days after operation. Potential PHC was considered in 7 other patients, whose pulmonary artery pressure increased and exceeded systemic arterial pressure, oxygen saturation decreased, and central venous pressure and vital signs were relatively stable. Univariate analysis showed that the risk factors of PHC in children with IPAH undergoing cardiac catheterization were younger age ( t= 3.160, P= 0.004), low weight ( t= 4.004, Phistory of syncope (χ(2)=4.948, P= 0.026), and WHO cardiac functional class Ⅲ or Ⅳ (χ(2)=19.013, Pcatheterization. WHO cardiac functional class may be associated with PHC. Integrated treatment is required for these patients. Reducing risk factors, early identification, and active treatment may help to prevent the occurrence and progression of PHC.

    2009-01-01

    Full Text Available Alkaptonuria is a rare autosomal recessive metabolic disorder that may present with multi-system involvement such as ochronotic arthropathy, renal, urethral and prostatic calculi, cardiac valvular lesions and pigmentation of the skin, sclera, cartilage and other connective tissues. An association of the disease with uveitis has never been reported. We report the first case of alkaptonuria with ochronotic arthropathy presenting with recurrent acute anterior uveitis as the initial manifestation.

    The scope of clinical and laboratory manifestations of the antiphospholipid syndrome (APS) has increased dramatically since its discovery in 1983, where any organ system can be involved. Musculoskeletal complications are consistently reported in APS patients, not only causing morbidity and mortality, but also affecting their quality of life. We reviewed all English papers on APS involvement in the musculoskeletal system using Google Scholar and Pubmed; all reports are summarized in a table in this review. The spectrum of manifestations includes arthralgia/arthritis, avascular necrosis of bone, bone marrow necrosis, complex regional pain syndrome type-1, muscle infarction, non-traumatic fractures, and osteoporosis. Some of these manifestations were reported in good quality studies, some of which showed an association between aPL-positivity and the occurrence of these manifestations, while others were merely described in case reports. © The Author(s) 2016.

    Current preoperative cardiac risk stratification practices group operations into broad categories, which might inadequately consider the intrinsic cardiac risks of individual operations. We sought to define the intrinsic cardiac risks of individual operations and to demonstrate how grouping operations might lead to imprecise estimates of perioperative cardiac risk. Elective operations (based on Common Procedural Terminology codes) performed from January 1, 2010 to December 31, 2015 at hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program were studied. A composite measure of perioperative adverse cardiac events was defined as either cardiac arrest requiring cardiopulmonary resuscitation or acute myocardial infarction. Operations' intrinsic cardiac risks were derived from mixed-effects models while controlling for patient mix. Resultant risks were sorted into low-, intermediate-, and high-risk categories, and the most commonly performed operations within each category were identified. Intrinsic operative risks were also examined using a representative grouping of operations to portray within-group variation. Sixty-six low, 30 intermediate, and 106 high intrinsic cardiac risk operations were identified. Excisional breast biopsy had the lowest intrinsic cardiac risk (overall rate, 0.01%; odds ratio, 0.11; 95% CI, 0.02 to 0.25) relative to the average, whereas aorto-bifemoral bypass grafting had the highest (overall rate, 4.1%; odds ratio, 6.61; 95% CI, 5.54 to 7.90). There was wide variation in the intrinsic cardiac risks of operations within the representative grouping (median odds ratio, 1.40; interquartile range, 0.88 to 2.17). A continuum of intrinsic cardiac risk exists among operations. Grouping operations into broad categories inadequately accounts for the intrinsic cardiac risk of individual operations.

    Skin Aging manifests primarily with wrinkles, dyspigmentations, texture changes, and loss of elasticity. During the skin aging process, there is a loss of moisture and elasticity in skin resulting in loss of firmness finally leading to skin sagging. The key molecule involved in skin moisture is hyaluronic acid (HA), which has a significant water-binding capacity. HA levels in skin decline with age resulting in decrease in skin moisture, which may contribute to loss of firmness. Clinical trials have shown that topically applied ROL effectively reduces wrinkles and helps retain youthful appearance. In the current study, ROL was shown to induce HA production and stimulates the gene expression of all three forms of hyaluronic acid synthases (HAS) in normal human epidermal keratinocytes monolayer cultures. Moreover, in human skin equivalent tissues and in human skin explants, topical treatment of tissues with a stabilized-ROL formulation significantly induced the gene expression of HAS mRNA concomitant with an increased HA production. Finally, in a vehicle-controlled human clinical study, histochemical analysis confirmed increased HA accumulation in the epidermis in ROL-treated human skin as compared to vehicle. These results show that ROL increases skin expression of HA, a significant contributing factor responsible for wrinkle formation and skin moisture, which decrease during aging. Taken together with the activity to increase collagen, elastin, and cell proliferation, these studies establish that retinol provides multi-functional activity for photodamaged skin.

    The optical model of birefringent networks of biological tissues is presented. The technique of Fourier polarimetry for selection of manifestations of linear and circular birefringence of protein fibrils is suggested. The results of investigations of statistical (statistical moments of the 1st-4th orders), correlation (dispersion and excess of autocorrelation functions) and scalar-self-similar (logarithmic dependencies of power spectra) structure of Fourier spectra of polarization azimuths distribution of laser images of skin samples are presented. The criteria of differentiation of postoperative biopsy of benign (keratoma) and malignant (adenocarcinoma) skin tumors are determined.

  1. Ocular manifestations of leptospirosis

    Full Text Available Leptospiral uveitis is a common entity in tropical countries. Ocular manifestations are noted in the second phase of illness, but these remain under-diagnosed mainly because of the prolonged symptom-free period that separates the systemic manifestations from detection of ocular manifestations.Varying ophthalmic presentations and the intrinsic nature of different types of uveitis to mimic one another also challenge the accuracy of the diagnosis. Of the individual ocular signs, the combination of acute, non-granulomatous, panuveitis, hypopyon, vasculitis, optic disc edema, membranous vitreous opacities and absence of choroiditis or retinitis have high predictive value for the clinical diagnosis of leptospiral uveitis. Geographic location of the patient, occupation, socio-economic status, risk factors related to exposure, past history of fever or jaundice also aid in diagnosis.Steroids are the mainstay of treatment for leptospiral uveitis. Depending upon the severity and anatomical location of inflammatory lesion, topical, peri-ocular and/or systemic steroids are given. The prognosis is generally good, even when the inflammation is severe.

    Using Indium-113m and the Gamma Retina V (Fucks-Knipping Camera), the minimal cardiac transit times (MTTs) were measured radiocardiographically from the right auricle to the aortic root. This analysis served to determine the relation between stroke volume and the segment volume of the part of circulation between the right auricle and the aortic root. In 39 patients with myocardial insufficiency of different clinical degree the effectiveness of digitalization was, up to a period of 5 years, measured by means of the volume relation mentioned above. The following conclusions can be drawn from the results: digitalization of patients with myocardial insufficiency leads to an improvement of the impaired relation of central volumes. In patients with diminished cardiac reserve the improvement is drastic and often results in a nearly complete normalization. The data remain constant during therapy even for an observation period of 5 years. Digitalization of patients with congestive heart failure only leads to a partial improvement. In contrast to patients with diminished cardiac reserve this effect is temporary. The different behaviour of the relation between stroke volume and segment volume in patients with diminished cardiac reserve and congestive heart failure under prolonged administration of digitalis points to the necessity of treatment with digitalis in the early stage of myocardial disease.

  3. Genetic Syndromes Associated with Congenital Cardiac Defects and Ophthalmologic Changes - Systematization for Diagnosis in the Clinical Practice

    Directory of Open Access Journals (Sweden)

    Priscila H. A. Oliveira

    Full Text Available Abstract Background: Numerous genetic syndromes associated with heart disease and ocular manifestations have been described. However, a compilation and a summarization of these syndromes for better consultation and comparison have not been performed yet. Objective: The objective of this work is to systematize available evidence in the literature on different syndromes that may cause congenital heart diseases associated with ocular changes, focusing on the types of anatomical and functional changes. Method: A systematic search was performed on Medline electronic databases (PubMed, Embase, Cochrane, Lilacs of articles published until January 2016. Eligibility criteria were case reports or review articles that evaluated the association of ophthalmic and cardiac abnormalities in genetic syndrome patients younger than 18 years. Results: The most frequent genetic syndromes were: Down Syndrome, Velo-cardio-facial / DiGeorge Syndrome, Charge Syndrome and Noonan Syndrome. The most associated cardiac malformations with ocular findings were interatrial communication (77.4%, interventricular communication (51.6%, patent ductus arteriosus (35.4%, pulmonary artery stenosis (25.8% and tetralogy of Fallot (22.5%. Conclusion: Due to their clinical variability, congenital cardiac malformations may progress asymptomatically to heart defects associated with high morbidity and mortality. For this reason, the identification of extra-cardiac characteristics that may somehow contribute to the diagnosis of the disease or reveal its severity is of great relevance.

    Neurofibromatosis type 1 (NF1) is the most common neurocutaneous syndrome and probably the one best known to dermatologists. Although the genetic locus of NF1 was identified on chromosome 17 in 1987, diagnosis of the disease is still based primarily on clinical observations. The 7 diagnostic criteria of the National Institutes of Health, which were established in 1988, include 3 skin manifestations (café-au-lait spots, freckling on flexural areas, and cutaneous neurofibromas). The age at which these diagnostic lesions appear is variable: onset can be late in some patients while others never develop certain symptoms. Definitive diagnosis may therefore be delayed by years. Although the appearance of the characteristic café-au-lait spots and freckling in the early years of childhood are very suggestive of the disease, these signs are not pathognomonic and, in isolation, do not constitute sufficient evidence to establish a definitive diagnosis. Thus, other diagnoses should be considered in patients whose only symptoms are café-au-lait spots and freckling. By contrast, the presence of multiple cutaneous neurofibromas or at least 1 plexiform neurofibroma is a very specific indication of NF1. Identification of the different types of neurofibroma allows us to confirm the diagnosis and initiate appropriate management. Copyright © 2016 AEDV. Published by Elsevier España, S.L.U.

    Cardiovascular-related adverse drug effects are a major concern for the pharmaceutical industry. Activity of an investigational drug at the L-type calcium channel could manifest in a number of ways, including changes in cardiac contractility. The aim of this study was to define which of the two assay technologies – radioligand-binding or automated electrophysiology – was most predictive of contractility effects in an in vitro myocyte contractility assay. The activity of reference and proprietary compounds at the L-type calcium channel was measured by radioligand-binding assays, conventional patch-clamp, automated electrophysiology, and by measurement of contractility in canine isolated cardiac myocytes. Activity in the radioligand-binding assay at the L-type Ca channel phenylalkylamine binding site was most predictive of an inotropic effect in the canine cardiac myocyte assay. The sensitivity was 73%, specificity 83% and predictivity 78%. The radioligand-binding assay may be run at a single test concentration and potency estimated. The least predictive assay was automated electrophysiology which showed a significant bias when compared with other assay formats. Given the importance of the L-type calcium channel, not just in cardiac function, but also in other organ systems, a screening strategy emerges whereby single concentration ligand-binding can be performed early in the discovery process with sufficient predictivity, throughput and turnaround time to influence chemical design and address a significant safety-related liability, at relatively low cost. - Highlights: • The L-type calcium channel is a significant safety liability during drug discovery. • Radioligand-binding to the L-type calcium channel can be measured in vitro. • The assay can be run at a single test concentration as part of a screening cascade. • This measurement is highly predictive of changes in cardiac myocyte contractility

    This study analyzed the effects of the chronic administration of clofibrate, a peroxisome proliferator-activated receptor-alpha (PPARalpha) agonist, on the development and established hemodynamic, morphologic, metabolic, and renal manifestations of hyperthyroidism in rats. The prevention study used four groups of male Wistar rats: control, clofibrate (240 mg/kg/day by gavage), T(4)(75 microg thyroxine/rat/day s.c.), and T(4)+clofibrate. All treatments were maintained for 3 weeks. Body weight (BW), tail systolic blood pressure (SBP), and heart rate (HR) were recorded weekly. Finally, temperature, SBP, pulse pressure (PP) and HR were recorded in conscious rats, and morphologic, metabolic, plasma, and renal variables were measured. The reversion study used two groups of rats, T(4)(treated for 6 weeks) and T(4)+clofibrate, measuring their hemodynamic variables and temperature for 3 weeks. T(4) increased BP, HR, PP, and temperature when compared with control rats. Clofibrate prevented and reversed the increase in SBP, HR, PP, and temperature produced by T(4) administration, reduced plasma thyroid hormone levels, and increased plasma thyroid-stimulating hormone values and phenol-uridine diphosphate-glucuronosyl-transferase (UGT) activity. However, clofibrate did not modify the cardiac or renal hypertrophy, polyphagia, polydipsia, or proteinuria of hyperthyroid rats. In normal rats, clofibrate treatment did not significantly change thyroid hormone levels, phenol-UGT activity, or any hemodynamic, morphologic, or renal variables. Chronic clofibrate treatment suppressed the hemodynamic manifestations and increased temperature of hyperthyroidism, an effect that can be produced by direct antithyroid effects. However, clofibrate administration did not modify the morphologic, metabolic, or renal alterations of hyperthyroid rats, indicating specificity in the antithyroid actions of clofibrate.

    Alterations in myocardial wall texture stand out among ADPKD cardiovascular manifestations, in hypertensive and normotensive patients. To elucidate their pathogenesis, we analyzed the cardiac phenotype in Pkd1cond/cond:Nestincre (CYG+) cystic mice exposed to increased blood pressure, at 5–6 and 20–24 weeks of age, and Pkd1+/− (HTG+) noncystic mice at 5–6 and 10–13 weeks. Echocardiographic analyses revealed decreased myocardial deformation and systolic function in CYG+ and HTG+ mice, as well as diastolic dysfunction in older CYG+ mice, compared to their Pkd1cond/cond and Pkd1+/+ controls. Hearts from CYG+ and HTG+ mice presented reduced polycystin-1 expression, increased apoptosis and mild fibrosis. Since galectin-3 has been associated with heart dysfunction, we studied it as a potential modifier of the ADPKD cardiac phenotype. Double-mutant Pkd1cond/cond:Nestincre;Lgals3−/− (CYG−) and Pkd1+/−;Lgals3−/− (HTG−) mice displayed improved cardiac deformability and systolic parameters compared to single-mutants, not differing from their controls. CYG− and HTG− showed decreased apoptosis and fibrosis. Analysis of a severe cystic model (Pkd1V/V; VVG+) showed that Pkd1V/V;Lgals3−/− (VVG−) mice have longer survival, decreased cardiac apoptosis and improved heart function compared to VVG+. CYG− and VVG− animals showed no difference in renal cystic burden compared to CYG+ and VVG+ mice. Thus, myocardial dysfunction occurs in different Pkd1-deficient models and suppression of galectin-3 expression rescues this phenotype. PMID:27475230

    Full Text Available Crohn’s disease is an inflammatory bowel disease which causes inflammation of the digestive tract. Crohn’s disease most frequently affects the ileum and the colon. In the active stage of the disease signs and symptoms may include diarrhea, abdominal pain and cramping, blood in the stools, reduced appetite and weight loss. In patients with severe Crohn’s disease the following signs and symptoms may be observed: fever, fatigue, arthritis, eye inflammation, oral ulcers, skin disorders, inflammation of the liver or bile ducts or delayed growth. Heredity and dysfunctions of the immune system are considered to cause the development of Crohn’s disease. About 10% of people with inflammatory bowel disease have also ocular problems. The most common ocular manifestations of Crohn’s disease are uveitis, iritis, episcleritis, keratopathy, keratoconjunctivitis and retinal vasculitis. Untreated uveitis may cause glaucoma and vision loss. Uveitis and iritis are four times more common in women than in men. In patients in the active stage of the disease, episcleritis also flares. Symptoms of episcleritis include inflammation, bright red spots on the sclera and localized pain. Keratoconjunctivitis in Crohn’s disease is caused by decreased tear production or increased tear film evaporation. Dry eyes can cause itching, burning or infection. Keratopathy usually causes no pain or vision loss, therefore in most cases no treatment is needed. In retinal vasculitis tortuosity of retinal veins, retinal edema at the posterior pole and intraretinal blood near blood vessels are observed. Intravenous fluorescein angiography shows intraretinal neovascularisation and haemorrhage in the posterior pole.

    Human-induced pluripotent stem cell (hiPSC)-derived cardiomyocytes are likely to revolutionize electrophysiological approaches to arrhythmias. Recent evidence suggests the somatic cell origin of hiPSCs may influence their differentiation potential. Owing to their cardiomyogenic potential, cardiac-stromal progenitor cells (CPCs) are an interesting cellular source for generation of hiPSC-derived cardiomyocytes. The effect of ionic current blockade in hiPSC-derived cardiomyocytes generated from CPCs has not been characterized yet. Human-induced pluripotent stem cell-derived cardiomyocytes were generated from adult CPCs and skin fibroblasts from the same individuals. The effect of selective ionic current blockade on spontaneously beating hiPSC-derived cardiomyocytes was assessed using multi-electrode arrays. Cardiac-stromal progenitor cells could be reprogrammed into hiPSCs, then differentiated into hiPSC-derived cardiomyocytes. Human-induced pluripotent stem cell-derived cardiomyocytes of cardiac origin showed higher upregulation of cardiac-specific genes compared with those of fibroblastic origin. Human-induced pluripotent stem cell-derived cardiomyocytes of both somatic cell origins exhibited sensitivity to tetrodotoxin, a blocker of Na +  current (I Na ), nifedipine, a blocker of L-type Ca 2+  current (I CaL ), and E4031, a blocker of the rapid component of delayed rectifier K +  current (I Kr ). Human-induced pluripotent stem cell-derived cardiomyocytes of cardiac origin exhibited sensitivity to JNJ303, a blocker of the slow component of delayed rectifier K +  current (I Ks ). In hiPSC-derived cardiomyocytes of cardiac origin, I Na , I CaL , I Kr , and I Ks were present as tetrodotoxin-, nifedipine-, E4031-, and JNJ303-sensitive currents, respectively. Although cardiac differentiation efficiency was improved in hiPSCs of cardiac vs. non-cardiac origin, no major functional differences were observed between hiPSC-derived cardiomyocytes of different somatic

    Recent advancements have promoted the use of T2* magnetic resonance imaging (MRI) in the non-invasive detection of iron overload in various organs for thalassemia major patients. This study aims to determine the iron load in the heart and liver of patients with thalassemia major using T2* MRI and to evaluate its correlation with serum ferritin level and iron chelation therapy. This cross-sectional study included 162 subjects diagnosed with thalassemia major, who were classified into acceptable, mild, moderate, or severe cardiac and hepatic iron overload following their T2* MRI results, respectively, and these were correlated to their serum ferritin levels and iron chelation therapy. The study found that 85.2% of the subjects had normal cardiac iron stores. In contrast, 70.4% of the subjects had severe liver iron overload. A significant but weak correlation (r = -0.28) was found between cardiac T2* MRI and serum ferritin, and a slightly more significant correlation (r = 0.37) was found between liver iron concentration (LIC) and serum ferritin. The findings of this study are consistent with several other studies, which show that patients generally manifest with liver iron overload prior to cardiac iron overload. Moreover, iron accumulation demonstrated by T2* MRI results also show a significant correlation to serum ferritin levels. This is the first study of its kind conducted in Indonesia, which supports the fact that T2* MRI is undoubtedly valuable in the early detection of cardiac and hepatic iron overload in thalassemia major patients.

    2014-01-01

    This book covers the main mathematical and numerical models in computational electrocardiology, ranging from microscopic membrane models of cardiac ionic channels to macroscopic bidomain, monodomain, eikonal models and cardiac source representations. These advanced multiscale and nonlinear models describe the cardiac bioelectrical activity from the cell level to the body surface and are employed in both the direct and inverse problems of electrocardiology. The book also covers advanced numerical techniques needed to efficiently carry out large-scale cardiac simulations, including time and space discretizations, decoupling and operator splitting techniques, parallel finite element solvers. These techniques are employed in 3D cardiac simulations illustrating the excitation mechanisms, the anisotropic effects on excitation and repolarization wavefronts, the morphology of electrograms in normal and pathological tissue and some reentry phenomena. The overall aim of the book is to present rigorously the mathematica...

    The mechanisms responsible for the variable manifestations of chronic cutaneous graft-vs-host disease (cGVHD) are poorly understood. Localization of sclerotic-type chronic graft-vs-host disease to sites of skin injury (isomorphic and isotopic responses), a recognized phenomenon in morphea, suggests a potential common pathway between cGVHD and other sclerotic skin conditions. Four cases of sclerotic-type cGVHD developed at the site of disparate skin injuries (ionizing radiotherapy, repeated needle sticks, central catheter site, and varicella-zoster virus infection). We review the spectrum of previously reported cases of sclerotic and nonsclerotic cGVHD relating to external forces on the skin. Localization of sclerotic-type cGVHD may occur after many types of skin injury, including UV and ionizing radiotherapy, needle sticks, viral infection, and pressure or friction. Recognition of this phenomenon may be helpful for the early diagnosis of sclerotic disease. Recent insights into the immunological consequences of minor skin injury may provide important clues to the underlying pathogenesis of cGVHD-mediated skin disease.

    Tuberous sclerosis complex (TSC) is a genetically determined hamartomatous neurocutaneous disease with high phenotypic variability. TSC is characterized by widespread hamartomas and benign, or rarely malignant, neoplasms distributed in several organs throughout the body, especially in the brain, skin, retina, kidney, heart, and lung. Common manifestations include cortical tubers, subependymal nodules, white matter abnormalities, retinal abnormalities, cardiac rhabdomyoma, lymphangioleiomyomatosis, renal angiomyolipoma, and skin lesions. The wide range of organs affected by the disease implies that TSC1 and TSC2 genes play important roles in the regulation of cell proliferation and differentiation. Although recent advances in treatment have improved morbidity, the prognosis remains quite poor and nearly 40% of patients die by the age of 35 years. Imaging is important in the evaluation of TSC because of its role not only in presumptive diagnosis, but also in defining the full extent of involvement. This information allows a better understanding of the behavioural phenotype, as related to lesion location. Imaging also contributes to treatment planning. This pictorial review describes common and uncommon imaging manifestations of TSC. (author)

    Oral infection contributes to atherosclerosis and coronary heart disease. We hypothesized that dental caries may be associated with out-of-hospital cardiac arrests (OHCA) of cardiac origin, but not non-cardiac origin. We compared the age-adjusted incidence of OHCA (785,591 cases of OHCA: 55.4% of cardiac origin and 44.6% of non-cardiac origin) to the age-adjusted prevalence of dental caries between 2005 and 2011 in the 47 prefectures of Japan. In both the total population and males over 65 years, the number of cases of dental caries was significantly associated with the number of OHCA of total and cardiac origin from 2005 to 2011, but not those of non-cardiac origin. In the total population, the age-adjusted prevalence of dental caries was not significantly associated with the age-adjusted incidence of OHCA (total OHCA: r correlation coefficient=0.22, p=0.14; OHCA of cardiac origin: r=0.25, p=0.09; OHCA of non-cardiac origin: r=-0.002, p=0.99). Among male patients over 65 years, the age-adjusted prevalence of dental caries was significantly associated with OHCA of total and cardiac origin, but not non-cardiac origin (total OHCA: r=0.47, p<0.001; OHCA of cardiac origin: r=0.37, p=0.01; OHCA of non-cardiac origin: r=0.28, p=0.054). While oral hygiene is important in all age groups, it may be particularly associated with OHCAs of cardiac origin in males over 65 years. Copyright © 2015. Published by Elsevier Ltd.

    The objective of this study was to investigate the patient and staff doses in the most frequent interventional cardiology (IC) procedures performed in Onassio, the largest Cardiac Centre in Greece. Data were collected from three digital X-ray systems for 212 coronary angiographies, 203 percutaneous transluminal coronary angio-plasties (PTCA) and 134 various electrophysiological studies. Patient skin dose was measured using suitably calibrated slow radiotherapy films and cardiologist dose using suitably calibrated thermoluminescent dosemeters placed on left arm, hand and foot. Patient median dose area product (DAP) (all examinations) ranged between 6.7 and 83.5 Gy cm 2 . Patient median skin dose in PTCA was 799 mGy (320-1660 mGy) and in RF ablation 160 mGy (35-1920 mGy). Median arm, hand and foot dose to the cardiologist were 12.6, 27 and 13 μSv, respectively, per procedure. The great range of radiation doses received by both patients and operators confirms the need for continuous monitoring of all IC techniques. (authors)

    Full Text Available Abstract Ehlers Danlos syndrome (EDS athrocalasia type (type VII, is characterized by joint hypermobility, skin hyperextensibility and tissue fragility. No heart involvement has been reported. Two forms have been described: type VII A and VII B. The abnormally processed collagen α2(I and the skipping of the exon 6 in COL1A2 gene are typically detected in EDS type VII B. We describe a seven-year old female, with a phenotype consistent with EDS type VII B and a diagnosis further confirmed by biochemical and molecular analyses. Cardiac ultrasound showed normal data in the first year of life. When she was 5 years old, the patient developed mitral valve regurgitation, and aortic and tricuspidal insufficiency at 7 years of age. To our knowledge, this is the first report of cardiac valvular involvement in EDS VII B. This feature probably has been underreported for the limited follow-up of the patients. Echocardiography might be warranted in the clinical assessment of EDS VII patients.

    Full Text Available Sudden cardiac death is one of the most common cause of mortality worldwide. Despite significant advances in the medical science, there is little improvement in the sudden cardiac death related mortality. Coronary artery disease is the most common etiology behind sudden cardiac death, in the above 40 years population. Even in the apparently healthy population, there is a small percentage of patients dying from sudden cardiac death. Given the large denominator, this small percentage contributes to the largest burden of sudden cardiac death. Identification of this at risk group among the apparently healthy individual is a great challenge for the medical fraternity. This article looks into the causes and methods of preventing SCD and at some of the Indian data. Details of Brugada syndrome, Long QT syndrome, Genetics of SCD are discussed. Recent guidelines on many of these causes are summarised.

  20. Proposed derivation of skin contamination and skin decontamination limits

    From the primary dose limits for the skin, secondary dose limits were derived for skin contamination which can be used in practical radiation protection work. Analogous to the secondary dose limit for the maximum permissible body burden in the case of incorporation, dose limits for the 'maximum permissible skin burden' were calculated, with the help of dose factors, for application in the case of skin contamination. They can be derived from the skin dose limit values. For conditions in which the skin is exposed to temporary contamination, a limit of skin contamination was derived for immediately removable contamination and for one day of exposure. For non-removable contamination a dose limit of annual skin contamination was defined, taking into account the renewal of the skin. An investigation level for skin contamination was assumed, as a threshold, above which certain measures must be taken; these to include appropriate washing not more than three times, with the subsequent procedure determined by the level of residual contamination. The dose limits are indicated for selected radionuclides. (author)

    Marta Miró-Murillo

    Full Text Available Von Hippel Lindau (Vhl gene inactivation results in embryonic lethality. The consequences of its inactivation in adult mice, and of the ensuing activation of the hypoxia-inducible factors (HIFs, have been explored mainly in a tissue-specific manner. This mid-gestation lethality can be also circumvented by using a floxed Vhl allele in combination with an ubiquitous tamoxifen-inducible recombinase Cre-ER(T2. Here, we characterize a widespread reduction in Vhl gene expression in Vhl(floxed-UBC-Cre-ER(T2 adult mice after dietary tamoxifen administration, a convenient route of administration that has yet to be fully characterized for global gene inactivation. Vhl gene inactivation rapidly resulted in a marked splenomegaly and skin erythema, accompanied by renal and hepatic induction of the erythropoietin (Epo gene, indicative of the in vivo activation of the oxygen sensing HIF pathway. We show that acute Vhl gene inactivation also induced Epo gene expression in the heart, revealing cardiac tissue to be an extra-renal source of EPO. Indeed, primary cardiomyocytes and HL-1 cardiac cells both induce Epo gene expression when exposed to low O(2 tension in a HIF-dependent manner. Thus, as well as demonstrating the potential of dietary tamoxifen administration for gene inactivation studies in UBC-Cre-ER(T2 mouse lines, this data provides evidence of a cardiac oxygen-sensing VHL/HIF/EPO pathway in adult mice.

    Full Text Available Threadlike filarial nematodes have been identified as the causative agent of filariasis. Cutaneous filariasis is caused primarily by Loa loa, Onchocerca volvulus, and Mansonella streptocerca. These parasites occupy the subcutaneous layer of the skin. However, other filarial parasites are usually associated with varying degrees of dermatological manifestations. In the present discourse, two cases of cutaneous filariasis were diagnosed in two female patients (21 and 40 years old, respectively in Remitch Clinic and Maternity located in a nonriverine community in Ekpoma, Edo State, Nigeria. In this report, patients with body mass index (BMI of 18.97 and 23.45 kg/m2, respectively, presented on two different occasions at least 6 months apart with hyperpigmented skin lesions in the upper and lower limbs, respectively. There was associated intense pruritus with no evidence of lymphadenopathy and lymphoedema. Following laboratory confirmation of filariasis, the patients were placed on a single oral dose combination of albendazole (400 mg + ivermectin (200 mcg/kg, while oral doses of loratadine 10 mg were administered daily for 5 days. Patients were carefully followed up for 6 weeks during which recession of the lesion and untoward reactions were monitored. It was observed that within 6 weeks of treatment, there was a dramatic recession of skin lesion. Adverse effect reported from use of the combination was mild. This case report revealed that cutaneous filariasis is not an uncommon presentation of filariasis infestation in Nigeria. The report also validates the safety and efficacy of the combination in the management of cutaneous manifestation of the disease.

    A coordinated, multidisciplinary approach to care is essential for optimum management of the primary manifestations and secondary complications of Duchenne muscular dystrophy (DMD). Contemporary care has been shaped by the availability of more sensitive diagnostic techniques and the earlier use of therapeutic interventions, which have the potential to improve patients’ duration and quality of life. In part 2 of this update of the DMD care considerations, we present the latest recommendations for respiratory, cardiac, bone health and osteoporosis, and orthopaedic and surgical management for boys and men with DMD. Additionally, we provide guidance on cardiac management for female carriers of a disease-causing mutation. The new care considerations acknowledge the effects of long-term glucocorticoid use on the natural history of DMD, and the need for care guidance across the lifespan as patients live longer. The management of DMD looks set to change substantially as new genetic and molecular therapies become available. PMID:29395990

    Health-related quality of life (HRQOL) is an increasingly important issue in assessing the consequences of any surgical or medical intervention. Our study aimed to evaluate change in HRQOL 6 months after elective cardiac surgery and to identify specific predictors of poor HRQOL. In this prospective, single-center study, HRQOL was evaluated before and 6 months after surgery using the SF-36 questionnaire and its two components: the physical component summary (PCS) and the mental component summary (MCS). We distinguished patients with worsening of HRQOL according to the minimal clinically important difference. All consecutive adult patients undergoing cardiac surgery were included. 326 patients completed the preoperative and postoperative SF-36 questionnaires and 24 patients died before completing follow-up questionnaires. Based on the definition used, clinically significant deterioration of HRQOL was observed in 93 patients (26.6%) for PCS and 99 patients (28.2%) for MCS. Renal replacement for acute renal failure and mechanical ventilation for longer than 48 hours were independent risk factors for PCS and MCS worsening or death. Although our study showed overall improvement of QOL after cardiac surgery, over a quarter of the patients manifested deterioration of HRQOL at 6 months post-surgery. The findings from this study should help clinicians to inform patients about their likely postoperative functional status and quality of life. Copyright © 2018. Published by Elsevier Inc.

    Hypochrondroplasia is an inherited skeletal dysplasia that resembles achondroplasia in mild degree. Radiographic manifestations encountered in 12 affected individuals in South Africa include slight shortening of all segments of the tubular bones, moderate caudal diminution of the lumbar interpedicular distances, increased lumbar lordosis with cacral tilt and distal prolongation of the fibular. Hypochondroplasia can be distinguished from other osteochondrodystrophies such as achondroplasia, pseudo-achondroplasia and metaphyseal chondroplasia by the recognition of it clinical and radiographic manifestations.

    2011-01-01

    Many of the X-ray systems that are used for cardiac interventional radiology provide no way to evaluate the patient maximum skin dose (MSD). The authors report a new method for evaluating the MSD by using the cumulative patient entrance skin dose (ESD), which includes a back-scatter factor and the number of cine-angiography frames during percutaneous coronary intervention (PCI). Four hundred consecutive PCI patients (315 men and 85 women) were studied. The correlation between the cumulative ESD and number of cine-angiography frames was investigated. The irradiation and overlapping fields were verified using dose-mapping software. A good correlation was found between the cumulative ESD and the number of cine-angiography frames. The MSD could be estimated using the proportion of cine-angiography frames used for the main angle of view relative to the total number of cine-angiography frames and multiplying this by the cumulative ESD. The average MSD (3.0±1.9 Gy) was lower than the average cumulative ESD (4.6±2.6 Gy). This method is an easy way to estimate the MSD during PCI. (authors)

    The skin is a complex biological system and may suffer change according to the environmental factors, as higher temperatures can increase sebum excretion, presenting oiliness and acne. These alterations can persist during the aging and provoke more changes in aged skin. In this study we evaluated the mature oily skin characteristics using biophysical and skin imaging techniques. Sixty healthy female subjects, aged between 39 and 55 years old were recruited and separated into 2 groups according to their skin type: normal/dry and oily skin. The skin was evaluated in terms of stratum corneum water content, transepidermal water loss (TEWL) sebum content, dermis thickness and echogenicity, skin microrelief, and pores content. The mature oily skin presented no significant differences when compared to the normal/dry skin on the stratum corneum water content and TEWL parameters. The sebum content was significantly higher on the oily skin group. The microrelief analysis showed an increase of skin roughness values in the oily skin and increase of scaliness in the normal/dry skin. The oily skin showed lower dermis echogenicity mainly in the frontal region and higher dermis thickness when compared to normal/dry skin. The mature oily skin showed different characteristics from normal/dry skin in terms of sebum content, microrelief parameters, and dermis thickness. This way, the characterization of mature oily skin in an objective way is very important to development of dermocosmetic products for more effective treatments focused specially on this type of skin. © 2018 John Wiley & Sons A/S.

    Calorie restriction (CR) can modulate the features of obesity-related metabolic and cardiovascular diseases. We have recently characterized DahlS.Z-Lepr(fa)/Lepr(fa) (DS/obese) rats, derived from a cross between Dahl salt-sensitive and Zucker rats, as a new animal model of metabolic syndrome. DS/obese rats develop hypertension and manifest left ventricular remodeling and diastolic dysfunction, as well as increased cardiac oxidative stress and inflammation. We have now investigated the effects of CR on cardiac pathophysiology in DS/obese rats. DS/obese rats were fed either normal laboratory chow ad libitum or a calorie-restricted diet (65% of the average food intake for ad libitum) from 9 to 13 weeks. Age-matched homozygous lean (DahlS.Z-Lepr(+)/Lepr(+) or DS/lean) littermates served as controls. CR reduced body weight in both DS/obese and DS/lean rats, as well as attenuated the development of hypertension in DS/obese rats without affecting blood pressure in DS/lean rats. CR also reduced body fat content, ameliorated left ventricular hypertrophy, fibrosis, and diastolic dysfunction, and attenuated cardiac oxidative stress and inflammation in DS/obese rats. In addition, it increased serum adiponectin concentration, as well as downregulated the expression of angiotensin-converting enzyme and angiotensin II type 1A receptor genes in the heart of DS/obese rats. Our results thus show that CR attenuated obesity and hypertension, as well as left ventricular remodeling and diastolic dysfunction in DS/obese rats, with these latter effects being associated with reduced cardiac oxidative stress and inflammation.

    Spider mites such as the citrus red mite and the two-spotted spider mite have been demonstrated to be important allergens for fruit cultivating farmers. To evaluate the role of environmental exposure to spider mites in the sensitization and the clinical manifestations of asthma and rhinitis in children and adolescents living in urban and rural areas. A total of 16,624 subjects (aged 7 to 18 years) living in urban (metropolitan and non-metropolitan) and rural areas (apple orchards and citrus orchards) in Korea were evaluated by questionnaire and skin prick test for 11 common aeroallergens, including citrus red mite (CRM) and two-spotted spider mite (TSM). The positive skin response rates to TSM were 4.2% of 1,563 metropolitan subjects, 3.8% of 5,568 non-metropolitan subjects and 6.5% of 1,464 subjects living nearby apple farms, and that to CRM 15.6% of 8,029 living nearby citrus farms. The prevalence of current wheeze and rhinitis as reported on a questionnaire was higher among those with a history of visiting fruit farms once or more per year than among those without it (10% vs. 7.1%, 32.8% vs. 26.7%, for wheezing and rhinitis, respectively). Among those with wheezing or rhinitis, the positive skin responses to TSM or CRM were also higher among those with a history of visiting fruit farms than among those without one (11.2% vs. 6.6%, 13.0% vs. 6.6%, respectively), although the positive skin responses to house dust mites were similar in the both groups. Spider mites are common sensitizing allergens in children and adolescents exposed to them, and environmental exposure to these mites may represent an important risk factor in the sensitization and the clinical manifestations of asthma and rhinitis in children and adolescents living in rural and urban areas.

    Branding is a form of body art wherein third-degree burns are inflicted on the skin to produce permanent scars. This method of scarification is a common practice among many indigenous cultures and has become exceedingly common in western societies. As with other forms of body art, branding is not a manifestation of a psychiatric disorder but, rather, a method of self-expression. The process can be performed through the use of electrocautery, laser, chemicals, freezing, and hot metal. Complications arising from the procedure include acute infection, transmission of blood-borne pathogens, allergic reactions, and sequelae arising from third-degree burns. In addition, skin branding has been shown to be associated with substance abuse and high-risk behaviors among adolescents. The purpose of this article is to present the following case report and review to familiarize clinicians with this dangerous method of body art.

    Three types of small cardiac lesions were described and illustrated: (1) focal type of papillary muscle fibrosis, evidently a healed infarct of the papillary muscle present in 13% of the autopsies, is a histologically characteristic lesion associated with coronary artery disease and healed myocardial infarction; (2) diffuse type of papillary muscle fibrosis, probably an aging change present in almost half of the autopsies, is associated with sclerosis of the arteries in the papillary muscle, is identifiable histologically; and apparently is not associated with any cardiac abnormality; and (3) focal cardiac myocytolysis, a unique histologic lesion, usually multifocal without predilection for any area of the heart, is associated with ischemic heart disease, death due to cancer complicated by non-bacterial thrombotic endocarditis and microthrombi in small cardiac arteries as well as with other diseases. Differentiation of the 2 types of papillary muscle fibrosis is important in the study of papillary muscle and mitral valve dysfunction. Focal cardiac myocytolysis may contribute to the fatal extension of myocardial infarcts.

    2015-12-01

    Full Text Available Methylmalonicaciduia(MMAaccompanied with homocystinuria is a rare autosomal-recessive with congenital metabolic disorder of Vitamin B12. There are three subtypes, cblC, cblD, cblF, in which cblC is the most common one. The diagnostic tests are tandem mass spectrometry and gas chromatography-mass spectrometry. Tests for activity of enzyme in fibroblasts from skin, complementary assay and genetic analysis can be used to make the subtype clear. Early-onset patients, defined by onset of symptoms before the age of 1 year, may have severe ocular involvement, including visual loss, nystagmus, strabismus, retinopathy, maculopathy, optic atrophy, abnormal electroretinography. Late-onset patients, defined by onset of symptoms after the age of 4 year, rarely have ocular manifestations. The pathogenesis of the ophthalmic symptoms may be related to the high level of homocystine, oxidative stress and the abnormal development of nervous systems. The treatment for MMA accompanied with homocystinuria is mostly symptomatic based. Ophthalmic treatment is limited. Early supplement of methionine,GSH or other antioxidants may be helpful for retinopathy. There is no standard ophthalmological examination for those patients in China. It is critical to set up inter-departmental cooperation and early stage examination for the treatments and outcomes of the patients.

    The broad immunologic roles of autophagy span innate and adaptive immunity and are often manifested in inflammatory diseases. The immune effects of autophagy partially overlap with its roles in metabolism and cytoplasmic quality control but typically expand further afield to encompass unique...... immunologic adaptations. One of the best-appreciated manifestations of autophagy is protection against microbial invasion, but this is by no means limited to direct elimination of intracellular pathogens and includes a stratified array of nearly all principal immunologic processes. This Review summarizes...... the broad immunologic roles of autophagy. Furthermore, it uses the autophagic control of Mycobacterium tuberculosis as a paradigm to illustrate the breadth and complexity of the immune effects of autophagy....

  10. Radiofrequency catheter ablation: Relationship between fluoroscopic time and skin doses according to diagnoses. Basis to establish a quality assurance programme

    International Nuclear Information System (INIS)

    2001-01-01

    Radiofrequency Cardiac Catheter Ablation is an Interventional Radiology procedure of great complexity because the cardiologist needs a simultaneous evaluation of fluoroscopic images and electrophysiologic information. Therefore, the procedure typically involves extended fluoroscopic time that may cause radiation-skin injures to patients. Skin doses depend on many factors: equipment design features and its proper use, cardiologist practice, fluoroscopic time, irradiated areas, application of radiation protection recommendations, etc. We evaluate fluoroscopic time in relation to pathology and we estimate skin doses on 233 procedures at the Electrophysiology Laboratory in Casa de Galicia, Montevideo, Uruguay. Significant differences among the medians of fluoroscopic time were found in those procedures depending on diagnoses and results. Higher fluoroscopic time was found in flutter and auricular tachycardia (median was 83 minutes, p=0.0001). In successful procedures (almost 90%), median skin doses was 2.0 Grays (p=0.0001). On the basis of records information, the standard operating procedure and the clinical protocol, expanding close cooperation between the cardiologists and the experts in Radiation Protection will secure the establishment of an Assurance Quality Program.

    To evaluate the predictive value of brain natriuretic peptide (BNP) for assessment of cardiac risk before non-cardiac surgery. Consecutively treated patients (947 men, 643 women) whose BNP was measured before non-cardiac surgery were studied. Clinical and ECG variables were evaluated to identify predictors of postoperative cardiac events. Events occurred in 6% of patients: 21 cardiac deaths, 20 non-fatal myocardial infarctions, 41 episodes of pulmonary oedema and 14 patients with ventricular tachycardia. All of these patients had raised plasma BNP concentrations (best cut-off point 189 pg/ml). The only independent predictor of postoperative events was BNP (odds ratio 34.52, 95% confidence interval (CI) 17.08 to 68.62, p 300 pg/ml); postoperative event rates were 0%, 5%, 12% and 81%, respectively. In this population of patients evaluated before non-cardiac surgery, BNP is an independent predictor of postoperative cardiac events. BNP > 189 pg/ml identified patients at highest risk.

    In Churg-Strauss syndrome (CSS) it is important to detect cardiac involvement, which predicts poor prognosis. This study evaluated whether 123 I-metaiodobenzylguanidine (MIBG) scintigraphy could detect cardiac damage and predict cardiac events in CSS. 123 I-MIBG scintigraphy was performed in 28 patients with CSS, 12 of whom had cardiac involvement. The early and delayed heart to mediastinum ratio (early H/M and delayed H/M) and washout rate were calculated by using 123 I-MIBG scintigraphy and compared with those in control subjects. Early H/M and delayed H/M were significantly lower and the washout rate was significantly higher in patients with cardiac involvement than in those without and in controls (early H/M, p = 0.0024, p = 0.0001; delayed H/M, p = 0.0002, p = 0.0001; washout rate, p = 0.0012, p = 0.0052 vs those without and vs controls, respectively). Accuracy for detecting cardiac involvement was 86% for delayed H/M and washout rate and 79% for early H/M and B-type natriuretic peptide (BNP). Kaplan-Meier analysis showed significantly lower cardiac event-free rates in patients with early H/M ≤ 2.18 and BNP > 21.8 pg/ml than those with early H/M > 2.18 and BNP ≤ 21.8 pg/ml (log-rank test p = 0.006). Cardiac sympathetic nerve function was damaged in CSS patients with cardiac involvement. 123 I-MIBG scintigraphy was useful in detecting cardiac involvement and in predicting cardiac events. (orig.)

  15. Matching the skin barrier to the skin type.

    Peristomal skin problems are thought to be common (Herlufsson et al, 2006; Williams et al, 2010), and can interfere with the security of stoma products. Stoma patients are reliant on the integrity of their peristomal skin to maintain a normal lifestyle. Bekkers et al (1996) highlighted that, if the peristomal skin becomes damaged, it not only affects the person physically, but also psychologically, ultimately prolonging rehabilitation and adaptation to the stoma. Therefore, it can be concluded that maintaining skin integrity is a basic and essential skill in ensuring good stoma management. This article explores the assessment of four stoma patients, highlighting the importance of matching their skin type with their skin barrier for optimum skin protection. The patients have kindly agreed for their case studies to be published as a means of informing others. All names have been changed in line with Nursing and Midwifery Council (2010) guidelines to maintain patient confidentiality. This article was originally presented at the World Council of Enterostomal Therapists' (WCET) annual conference in 2010, receiving first prize at poster presentations.

    Full Text Available Lymphoma is a lymphoid tumor that originates in hematopoietic organs such as lymph node, spleen or liver. In dogs, the overall prevalence of cardiac tumors was estimated to be only 0.19% based on the results of the survey of a large database, and lymphomas accounts for approximately 2% of all cardiac tumors. In general, the involvement of the myocardium is rarely described in canine lymphoma. Currently, there is no evidence of a viral association with primary cardiac lymphoma in dogs, but other types of immunosuppression may contribute to abnormal events, such as involvement primary cardiac. The aim of this study was to analyze a case of sudden death of a bitch, SRD, aged 10, who had the final diagnosis of cardiac lymphoma.

    International Nuclear Information System (INIS)

    Manzke, Robert

    2005-01-01

    This doctoral thesis addresses imaging of the heart with retrospectively gated helical cone-beam computed tomography (CT). A thorough review of the CT reconstruction literature is presented in combination with a historic overview of cardiac CT imaging and a brief introduction to other cardiac imaging modalities. The thesis includes a comprehensive chapter about the theory of CT reconstruction, familiarizing the reader with the problem of cone-beam reconstruction. The anatomic and dynamic properties of the heart are outlined and techniques to derive the gating information are reviewed. With the extended cardiac reconstruction (ECR) framework, a new approach is presented for the heart-rate-adaptive gated helical cardiac cone-beam CT reconstruction. Reconstruction assessment criteria such as the temporal resolution, the homogeneity in terms of the cardiac phase, and the smoothness at cycle-to-cycle transitions are developed. Several reconstruction optimization approaches are described: An approach for the heart-rate-adaptive optimization of the temporal resolution is presented. Streak artifacts at cycle-to-cycle transitions can be minimized by using an improved cardiac weighting scheme. The optimal quiescent cardiac phase for the reconstruction can be determined automatically with the motion map technique. Results for all optimization procedures applied to ECR are presented and discussed based on patient and phantom data. The ECR algorithm is analyzed for larger detector arrays of future cone-beam systems throughout an extensive simulation study based on a four-dimensional cardiac CT phantom. The results of the scientific work are summarized and an outlook proposing future directions is given. The presented thesis is available for public download at www.cardiac-ct.net

    Skin and joint manifestations are part of the clinical spectrum of many disorders. Well-known associations include psoriatic arthritis and arthritis associated with autoimmune connective tissue diseases. This review focuses on less common associations where skin lesions can provide easily accessible and valuable diagnostic clues, and directly lead to the specific diagnosis or limit the list of possibilities. This may also affect health care resources as diagnostic tests are often low-specific, highly expensive and poorly available. This group of diseases can be divided into two subsets, based on the presence/absence of fever, and then further classified according to elementary skin lesions (macular, urticarial, maculo-papular, vesico-bullous, pustular, petechial and nodular). In most instances joint involvement occurs as peripheral migrating polyarthritis. Erythematosus macular or urticarial rashes occur in most febrile disorders such as monogenic autoinflammatory syndromes, Schnitzler's syndrome, Still's disease and rheumatic fever and afebrile diseases as urticarial vasculitis. Pustular rash may be observed in chronic recurrent multifocal osteomyelitis (CRMO) and pyogenic arthritis with pyoderma gangrenosum and acne (PAPA) syndrome (both febrile) as well as in Behcet's disease and Synovitis, acne, pustulosis, hyperostosis and osteitis syndrome (both non-febrile). Papular lesions are typical of secondary syphilis, sarcoidosis, interstitial granulomatous dermatitis, papular petechial of cutaneous small-vessel vasculitis and nodular lesions of polyarteritis nodosa and multicentric reticulohistiocytosis all of which are afebrile. Differential diagnosis includes infections and drug reactions which may mimic several of these conditions. To biopsy the right skin lesion at the right time it is essential to obtain relevant histological information. © 2013 European Academy of Dermatology and Venereology.

  20. Experimental study on tissue phantoms to understand the effect of injury and suturing on human skin mechanical properties.

    2017-01-01

    Skin injuries are the most common type of injuries occurring in day-to-day life. A skin injury usually manifests itself in the form of a wound or a cut. While a shallow wound may heal by itself within a short time, deep wounds require surgical interventions such as suturing for timely healing. To date, suturing practices are based on a surgeon's experience and may vary widely from one situation to another. Understanding the mechanics of wound closure and suturing of the skin is crucial to improve clinical suturing practices and also to plan automated robotic surgeries. In the literature, phenomenological two-dimensional computational skin models have been developed to study the mechanics of wound closure. Additionally, the effect of skin pre-stress (due to the natural tension of the skin) on wound closure mechanics has been studied. However, in most of these analyses, idealistic two-dimensional skin geometries, materials and loads have been assumed, which are far from reality, and would clearly generate inaccurate quantitative results. In this work, for the first time, a biofidelic human skin tissue phantom was developed using a two-part silicone material. A wound was created on the phantom material and sutures were placed to close the wound. Uniaxial mechanical tests were carried out on the phantom specimens to study the effect of varying wound size, quantity, suture and pre-stress on the mechanical behavior of human skin. Also, the average mechanical behavior of the human skin surrogate was characterized using hyperelastic material models, in the presence of a wound and sutures. To date, such a robust experimental study on the effect of injury and sutures on human skin mechanics has not been attempted. The results of this novel investigation will provide important guidelines for surgical planning and validation of results from computational models in the future.

    Electrospun microfiber meshes have been shown to support the proliferation and differentiation of many types of stem cells, but the phenotypic fate of c-kit{sup +} human cardiac stem cells (hCSCs) have not been explored. To this end, we utilized thin (~5 µm) elastomeric meshes consisting of aligned 1.7 µm diameter poly (ester-urethane urea) microfibers as substrates to examine their effect on hCSC viability, morphology, proliferation, and differentiation relative to cells cultured on tissue culture polystyrene (TCPS). The results showed that cells on microfiber meshes displayed an elongated morphology aligned in the direction of fiber orientation, lower proliferation rates, but increased expressions of genes and proteins majorly associated with cardiomyocyte phenotype. The early (NK2 homeobox 5, Nkx2.5) and late (cardiac troponin I, cTnI) cardiomyocyte genes were significantly increased on meshes (Nkx=2.5 56.2±13.0, cTnl=2.9±0.56,) over TCPS (Nkx2.5=4.2±0.9, cTnl=1.6±0.5, n=9, p<0.05 for both groups) after differentiation. In contrast, expressions of smooth muscle markers, Gata6 and myosin heavy chain (SM-MHC), were decreased on meshes. Immunocytochemical analysis with cardiac antibody exhibited the similar pattern of above cardiac differentiation. We conclude that aligned microfiber meshes are suitable for guiding cardiac differentiation of hCSCs and may facilitate stem cell-based therapies for treatment of cardiac diseases. - Highlights: • First study to characterize c-kit{sup +} human cardiac stem cells on microfiber meshes. • Microfiber meshes seem reducing cell proliferation, but no effect on cell viability. • Microfiber meshes facilitate the elongation of human cardiac stem cells in culture. • Cardiac but not smooth muscle differentiation were enhanced on microfiber meshes. • Microfiber meshes may be used as cardiac patches in cell-based cardiac therapy.

    Full Text Available Objective. To determine active TGF-β1 (aTGF-β1 levels in serum, skin, and peripheral blood mononuclear cell (PBMC culture supernatants and to understand their associations with clinical parameters in systemic sclerosis (SSc patients. Methods. We evaluated serum samples from 56 SSc patients and 24 healthy controls (HC. In 20 SSc patients, we quantified spontaneous or anti-CD3/CD28 stimulated production of aTGF-β1 by PBMC. The aTGF-β1 levels were measured by ELISA. Skin biopsies were obtained from 13 SSc patients and six HC, and TGFB1 expression was analyzed by RT-PCR. Results. TGF-β1 serum levels were significantly higher in SSc patients than in HC (p < 0.0001. Patients with increased TGF-β1 serum levels were more likely to have diffuse subset (p = 0.02, digital ulcers (p = 0.02, lung fibrosis (p < 0.0001, positive antitopoisomerase I (p = 0.03, and higher modified Rodnan score (p = 0.046. Most of our culture supernatant samples had undetectable levels of TGF-β1. No significant difference in TGFB1 expression was observed in the SSc skin compared with HC skin. Conclusion. Raised active TGF-β1 serum levels and their association with clinical manifestations in scleroderma patients suggest that this cytokine could be a marker of fibrotic and vascular involvement in SSc.

  5. Autonomic cardiac innervation

    Science.gov (United States)

    Hasan, Wohaib

    2013-01-01

    Autonomic cardiac neurons have a common origin in the neural crest but undergo distinct developmental differentiation as they mature toward their adult phenotype. Progenitor cells respond to repulsive cues during migration, followed by differentiation cues from paracrine sources that promote neurochemistry and differentiation. When autonomic axons start to innervate cardiac tissue, neurotrophic factors from vascular tissue are essential for maintenance of neurons before they reach their targets, upon which target-derived trophic factors take over final maturation, synaptic strength and postnatal survival. Although target-derived neurotrophins have a central role to play in development, alternative sources of neurotrophins may also modulate innervation. Both developing and adult sympathetic neurons express proNGF, and adult parasympathetic cardiac ganglion neurons also synthesize and release NGF. The physiological function of these “non-classical” cardiac sources of neurotrophins remains to be determined, especially in relation to autocrine/paracrine sustenance during development.   Cardiac autonomic nerves are closely spatially associated in cardiac plexuses, ganglia and pacemaker regions and so are sensitive to release of neurotransmitter, neuropeptides and trophic factors from adjacent nerves. As such, in many cardiac pathologies, it is an imbalance within the two arms of the autonomic system that is critical for disease progression. Although this crosstalk between sympathetic and parasympathetic nerves has been well established for adult nerves, it is unclear whether a degree of paracrine regulation occurs across the autonomic limbs during development. Aberrant nerve remodeling is a common occurrence in many adult cardiovascular pathologies, and the mechanisms regulating outgrowth or denervation are disparate. However, autonomic neurons display considerable plasticity in this regard with neurotrophins and inflammatory cytokines having a central regulatory

    It's shown that the gentilionic theory for quarks is manifestly confining for quarks and manifestly non-coalescent for hadrons, and that these properties are rigorously deduced only from first principles. To prove them no arguments involving the intrinsic nature of gentileons or dynamical hypothesis are necessary to be adopted. It's also shown that, in the context of the quantum field theory, gentileous can be taken approximately as fermions and that the usual quantum chromodynamics can be used to calculate the properties of gentilionic hadrons.

  8. Direct Cardiac Reprogramming: Advances in Cardiac Regeneration

    2015-01-01

    Full Text Available Heart disease is one of the lead causes of death worldwide. Many forms of heart disease, including myocardial infarction and pressure-loading cardiomyopathies, result in irreversible cardiomyocyte death. Activated fibroblasts respond to cardiac injury by forming scar tissue, but ultimately this response fails to restore cardiac function. Unfortunately, the human heart has little regenerative ability and long-term outcomes following acute coronary events often include chronic and end-stage heart failure. Building upon years of research aimed at restoring functional cardiomyocytes, recent advances have been made in the direct reprogramming of fibroblasts toward a cardiomyocyte cell fate both in vitro and in vivo. Several experiments show functional improvements in mouse models of myocardial infarction following in situ generation of cardiomyocyte-like cells from endogenous fibroblasts. Though many of these studies are in an early stage, this nascent technology holds promise for future applications in regenerative medicine. In this review, we discuss the history, progress, methods, challenges, and future directions of direct cardiac reprogramming.

    'Holi' is an annual spring festival celebrated all over India. The central ritual of Holi involves throwing of colors on one another. Playing with toxic industrial dyes often results in various dermatological complaints in a significant number of people immediately following the celebration. To describe patterns of various skin manifestations directly or indirectly related to the use of different colors in the celebration of Holi. Observational clinical study on consecutive patients presenting to a teaching hospital in Kolkata, India. Forty-two patients with a mean age of 24.2 years were studied. Itching was the commonest symptom (25, 59.5%), followed by burning sensation, pain, oozing, and scaling. Eleven patients' symptoms were attributed to activities related to preparation of colors and the removal of colors from the skin surface. Eczematous lesions were the most common pattern (24, 57.1%) followed by erosions, xerosis and scaling, erythema, urticaria, acute nail-fold inflammation, and abrasions. Thirteen (30.9%) patients reported aggravation of preexisting dermatoses (acne, eczema, and paronychia). Secondary pyoderma occurred in 3 (7.1%). Face was the commonest site affected (24, 57.1%), followed by dorsum of the hands, scalp, forearm, palms, arms, and trunk. Ocular complaints in the form of redness, watering, and grittiness occurred in 7 (16.7%) patients. Various forms of cutaneous manifestations, often associated with ocular complaints, occur commonly due to Holi colors. Public awareness and regulatory actions are needed to avoid these preventable conditions.

    Background: Radiation treatment may induce acute skin reactions. There are several methods of managing them. Validity of these methods, however, is not sufficiently studied. We therefore investigated, whether moist skin care with 3% urea lotion will reduce acute radiation skin toxicity. Patients and Methods: 88 patients with carcinomas of the head and neck undergoing radiotherapy with curative intent (mean total dose 60 Gy, range: 50-74 Gy) were evaluated weekly for acute skin reactions according to the RTOG-CTC score. In 63 patients, moist skin care with 3% urea lotion was performed. The control group consisted of 25 patients receiving conventional dry skin care. The incidence of grade I, II, and III reactions and the radiation dose at occurrence of a particular reaction were determined and statistically analyzed using the log-rank test. The dose-time relations of individual skin reactions are described. Results: At some point of time during radiotherapy, all patients suffered from acute skin reactions grade I, > 90% from grade II reactions. 50% of patients receiving moist skin care experienced grade I reactions at 26 Gy as compared to 22 Gy in control patients (p = 0.03). Grade II reactions occurred at 51 Gy versus 34 Gy (p = 0.006). Further, 22% of the patients treated with moist skin care suffered from acute skin toxicity grade III as compared to 56% of the controls (p = 0.0007). Conclusion: Moist skin care with 3% urea lotion delays the occurrence and reduces the grade of acute skin reactions in percutaneously irradiated patients with head and neck tumors. (orig.)

    Interleukin 33 (IL-33), a member of the IL-1 family and a ligand of the orphan receptor ST2, plays key roles in innate and adaptive immunity. We examined the associations between IL-33/ST2 levels and clinical manifestations of patients with active adult-onset Still's disease (AOSD). Blood samples were collected from 40 patients with active AOSD, 28 patients with rheumatoid arthritis (RA), and 27 healthy controls (HC). The serum levels of IL-33 and soluble ST2 were determined using ELISA. Expression levels of IL-33 and ST2 in biopsy specimens obtained from 34 AOSD patients with rash were immunohistochemically investigated. IL-33 levels of patients with AOSD were higher than those of patients with RA and HC. Soluble ST2 levels of patients with AOSD were higher than those of HC, but not of patients with RA. Serum IL-33 levels correlated with systemic score, erythrocyte sedimentation rate, ferritin levels, and aspartate transaminase levels. However, serum soluble ST2 levels correlated only with ferritin levels. The numbers of inflammatory cells expressing IL-33 and ST2 were elevated in skin lesions of patients with AOSD compared to HC, but did not differ from those of the skin lesions of eczema or psoriasis. We found significantly higher serum IL-33 and soluble ST2 levels in patients with active AOSD. Results indicate that the IL-33/ST2 signaling pathway may play a role in the pathogenesis of the acute inflammation and skin manifestations associated with AOSD.

    Full Text Available BACKGROUND This prospective study aimed to evaluate the incidence of ocular manifestations in head injury and their correlation with the intracranial lesions. MATERIALS AND METHODS A total of 108 consecutive cases of closed head injury admitted in the neurosurgical ward of a tertiary teaching hospital underwent a thorough ophthalmic assessment. Clinical examination, radiological imaging and Glasgow Coma Scale (GCS were applied to grade the severity of injury. RESULTS Total number of 108 patients of head injury were examined of which 38 patients had ocular manifestations (35.18%. Of these, 85.18% were males, 84% of injuries were due to road traffic accidents and 16% were due to fall from a height. The ocular manifestations were as follows- Orbital complications were seen in 6 patients (15.8%. Anterior segment manifestations included black eyes seen in 10 patients (26.3%, subconjunctival haemorrhage in 10.5% of patients (4 patients, corneal involvement in 21% of patients (8 patients and pupillary involvement in 50% of patients (19 patients. Posterior segment manifestations were seen in 26.3% of patients (10 patients and were as follows- Purtscher’s retinopathy in 2 patients and optic atrophy in 5 patients. Cranial nerve palsies were seen in 15 patients (39.47% and supranuclear movement disorders were seen in 3 patients (8%. CONCLUSION Even though, neurosurgeons perform comprehensive clinical examination including eye examination, the main purpose is limited to aid topical diagnosis of neurological lesions. This study emphasises the importance of a detailed eye examination by an ophthalmologist to prevent irreversible visual loss in addition to aiding in the neurological diagnosis. Pupillary involvement, papilloedema and ocular motor paresis pointed to a more severe head injury. This observational prospective study helped us to correlate the severity of head injuries in association with ocular findings in patients admitted in neurosurgical ward

    This chapter reviews the development of skin cancer associated with radiation, focusing on the knowledge of A-bomb radiation-induced skin cancer. Since the discovery of X radiation in 1895, acute and chronic radiation dermatitis has been the first matter of concern. Then, in 1902, skin cancer found among radiological personnel has posed a social problem. In earlier study determining the relationship between skin cancer and A-bomb radiation, there is no increase in the incidence of either skin cancer or precancerous condition during the first 20 years after A-bombing. More recent studies have showed that there is a significant correlation between the incidence of skin cancer and distance from the hypocenter; and the incidence of skin cancer is found to be remarkably increased since 1975 in the group exposed at ≤2,000 m. Excess relative risk is 2.2 at one Gy dose. The incidence of skin cancer is also found to be extremely increased with aging. Relative risk is high in younger A-bomb survivors at the time of exposure. Histologically, basal cell carcinoma is more senstitive to ionizing radiation than squamous cell carcinoma. (N.K.)

    Full Text Available The authors report a case of cardiac arrest in a patient receiving intravenous (IV metoclopramide and review the pertinent literature. A 62-year-old morbidly obese female admitted for a gastric sleeve procedure, developed cardiac arrest within one minute of receiving metoclopramide 10 mg via slow intravenous (IV injection. Bradycardia at 4 beats/min immediately appeared, progressing rapidly to asystole. Chest compressions restored vital function. Electrocardiogram (ECG revealed ST depression indicative of myocardial injury. Following intubation, the patient was transferred to the intensive care unit. Various cardiac dysrrhythmias including supraventricular tachycardia (SVT associated with hypertension and atrial fibrillation occurred. Following IV esmolol and metoprolol, the patient reverted to normal sinus rhythm. Repeat ECGs revealed ST depression resolution without pre-admission changes. Metoclopramide is a non-specific dopamine receptor antagonist. Seven cases of cardiac arrest and one of sinus arrest with metoclopramide were found in the literature. The metoclopramide prescribing information does not list precautions or adverse drug reactions (ADRs related to cardiac arrest. The reaction is not dose related but may relate to the IV administration route. Coronary artery disease was the sole risk factor identified. According to Naranjo, the association was possible. Other reports of cardiac arrest, severe bradycardia, and SVT were reviewed. In one case, five separate IV doses of 10 mg metoclopramide were immediately followed by asystole repeatedly. The mechanism(s underlying metoclopramide’s cardiac arrest-inducing effects is unknown. Structural similarities to procainamide may play a role. In view of eight previous cases of cardiac arrest from metoclopramide having been reported, further elucidation of this ADR and patient monitoring is needed. Our report should alert clinicians to monitor patients and remain diligent in surveillance and

    It has long been recognized that differences exist between men and women in the impact of risc factors, symptoms, development and outcome of special diseases like the cardiovascular disease. Gender determines the cardiac baseline parameters like the number of cardiac myocyte, size and demand and may suggest differences in myofilament function among genders, which might be pronounced under pathological conditions. Does gender impact and maybe impair the contractile apparatus? Are the differences more prominent when other factors like weight, age, ejection fraction are added?Therefore we performed a study on 36 patients (21 male, 15 female) undergoing aortic valve replacement (AVR) or aortocoronary bypass operation (CABG) to examine the influence of gender, ejection fraction, surgical procedure and body mass index (BMI) on cardiac force development. Tissue was obtained from the right auricle and was stored in a special solution to prevent any stretching of the fibers. We used the skinned muscle fiber model and single muscle stripes, which were mounted on the "muscle machine" and exposed to a gradual increase of calcium concentration calculated by an attached computer program. 1.) In general female fibers show more force than male fibers: 3.9 mN vs. 2.0 mN (p = 0.03) 2.) Female fibers undergoing AVR achieved more force than those undergoing CABG operation: 5.7 mN vs. 2.8 mN (p = 0.02) as well as male fibers with AVR showed more force values compared to those undergoing CABG: 2.0 mN vs. 0.5 mN (p = 0.01). 3.) Male and female fibers of patients with EF > 55% developed significantly more force than from those with less ejection fraction than 30%: p = 0.002 for the male fibers (1.6 vs. 2.8 mN) and p = 0.04 for the female fibers (5.7 vs. 2.8 mN). 4.) Patients with a BMI between 18 till 25 develop significant more force than those with a BMI > 30: Females 5.1 vs. 2.6 mN; p 0.03, Males 3.8 vs. 0.8 mN; p 0.04). Our data suggest that female patients undergoing AVR or CABG

    Full Text Available Dandruff is a prevalent chronic inflammatory skin condition of the scalp that has been associated with Malassezia yeasts. However, the microbial role has not been elucidated yet, and the etiology of the disorder remains poorly understood. Using high-throughput 16S rDNA and ITS1 sequencing, we characterized cutaneous bacterial and fungal microbiotas from healthy and dandruff subjects, comparing scalp and forehead (lesional and non-lesional skin sites. Bacterial and fungal communities from dandruff analyzed at genus level differed in comparison with healthy ones, presenting higher diversity and greater intragroup variation. The microbial shift was observed also in non-lesional sites from dandruff subjects, suggesting that dandruff is related to a systemic process that is not restricted to the site exhibiting clinical symptoms. In contrast, Malassezia microbiota analyzed at species level did not differ according to health status. A 2-step OTU assignment using combined databases substantially increased fungal assigned sequences, and revealed the presence of highly prevalent uncharacterized Malassezia organisms (>37% of the reads. Although clinical symptoms of dandruff manifest locally, microbial dysbiosis beyond clinically affected skin sites suggests that subjects undergo systemic alterations, which could be considered for redefining therapeutic approaches.

    Four patients with cardiac tumours were investigated by gated cardiac blood pool radionuclide imaging and echocardiography. Contrast angiocardiography was performed in three of the cases. Two left atrial tumours were detected by all three techniques. In one of these cases echocardiography alone showed additional mitral valve stenosis, but isotope imaging indicated tumour size more accurately. A large septal mass was detected by all three methods. In this patient echocardiography showed evidence of left ventricular outflow obstruction, confirmed at cardiac catheterisation, but gated isotope imaging provided a more detailed assessment of the abnormal cardiac anatomy. In the fourth case gated isotope imaging detected a large right ventricular tumour which had not been identified by echocardiography. Gated cardiac blood pool isotope imaging is a complementary technique to echocardiography for the non-invasive detection and assessment of cardiac tumours. (author)

    Full Text Available An epidemiological study was undertaken to study the incidence and distribution of orthopaedic manifestations of filariasis in an endemic area. A total of 207 cases were clinically examined and investigated. Patients were divided into three groups , viz., Group A: Orthopaedic manifestations with no history of filariasis . Group B: Orthopaedic manifestations with history of filariasis such as microfilaraemia or filarial fevers etc., Group C: Orthopaedic manifestations with chronic manifestations such as elephantiasis, hydrocele etc. To confirm filarial etiology, all the cases were examined for the presence of filarial antibody by indirect ELISA using wuchereda bancrofti microfilarial excretory- secretary antigen (wd Mf ESAg . A total of 61 of 102 patients of Group A, 14 of 21 patients of group B, and 73 of 84 patients of Group C were positive for filarial antibody. This study showed the prevalence of filarial antibody in about 71.4% of various orthopaedic manifestations.

    It has been found that exposure to heat and infrared radiation (IR) can be carcinogenic, and that a combination of ultraviolet radiation (UVR) and IR possibly amplifies carcinogenesis. To investigate how the skin temperature is affected by sunbathing, we measured the skin temperature on 20 healthy...... volunteers over 6 days' sun holiday in Egypt. Temperatures were measured with an infrared thermometer gun at 8 skin sites on the volunteers while they were indoors in the morning and when sunbathing during the day.

    Heterogeneity with respect to skin color tone is one of the key factors in visual perception of facial attractiveness and age. However, there have been few studies on quantitative analyses of the color heterogeneity of facial skin. The purpose of this study was to develop image evaluation methods for skin color heterogeneity focusing on skin chromophores and then characterize ethnic differences and age-related changes. A facial imaging system equipped with an illumination unit and a high-resolution digital camera was used to develop image evaluation methods for skin color heterogeneity. First, melanin and/or hemoglobin images were obtained using pigment-specific image-processing techniques, which involved conversion from Commission Internationale de l'Eclairage XYZ color values to melanin and/or hemoglobin indexes as measures of their contents. Second, a spatial frequency analysis with threshold settings was applied to the individual images. Cheek skin images of 194 healthy Asian and Caucasian female subjects were acquired using the imaging system. Applying this methodology, the skin color heterogeneity of Asian and Caucasian faces was characterized. The proposed pigment-specific image-processing techniques allowed visual discrimination of skin redness from skin pigmentation. In the heterogeneity analyses of cheek skin color, age-related changes in melanin were clearly detected in Asian and Caucasian skin. Furthermore, it was found that the heterogeneity indexes of hemoglobin were significantly higher in Caucasian skin than in Asian skin. We have developed evaluation methods for skin color heterogeneity by image analyses based on the major chromophores, melanin and hemoglobin, with special reference to their size. This methodology focusing on skin color heterogeneity should be useful for better understanding of aging and ethnic differences. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Chronic GVHD is one of the most severe complications of allogeneic HSCT. The sclerotic skin manifestations of cGVHD (ScGVHD) result from inflammation and fibrosis of the dermis, subcutaneous tissue, or fascia, leading to significant functional disability. Risk factors and clinical markers associated with ScGVHD remain largely unexamined. By using a single-visit, cross-sectional design, we evaluated 206 patients with cGVHD at the National Institutes of Health. Most patients manifested severe (ie, 63% National Institutes of Health score "severe"), refractory disease (median treatments = 4). ScGVHD was detected in 109 (52.9%) patients. ScGVHD was associated with greater platelet count (P < .001) and C3 (P < .001), and decreased forced vital capacity (P = .013). Total body irradiation (TBI) was associated with development of ScGVHD (P = .002). TBI administered in reduced-intensity conditioning was most strongly associated with ScGVHD (14/15 patients, P < .0001). Patients with ScGVHD had significant impairments of joint range of motion and grip strength (P < .001). Greater body surface area involvement was associated with poorer survival (P = .015). We conclude that TBI, particularly in reduced-intensity regimens, may be an important risk factor for ScGVHD. Widespread skin involvement is associated with significant functional impairment, distressing symptoms, and diminished survival. This trial is registered at http://www.clinicaltrials.gov as NCT00331968.

  6. Pregnancy as a cardiac stress model

    Cardiac hypertrophy occurs during pregnancy as a consequence of both volume overload and hormonal changes. Both pregnancy- and exercise-induced cardiac hypertrophy are generally thought to be similar and physiological. Despite the fact that there are shared transcriptional responses in both forms of cardiac adaptation, pregnancy results in a distinct signature of gene expression in the heart. In some cases, however, pregnancy can induce adverse cardiac events in previously healthy women without any known cardiovascular disease. Peripartum cardiomyopathy is the leading cause of non-obstetric mortality during pregnancy. To understand how pregnancy can cause heart disease, it is first important to understand cardiac adaptation during normal pregnancy. This review provides an overview of the cardiac consequences of pregnancy, including haemodynamic, functional, structural, and morphological adaptations, as well as molecular phenotypes. In addition, this review describes the signalling pathways responsible for pregnancy-induced cardiac hypertrophy and angiogenesis. We also compare and contrast cardiac adaptation in response to disease, exercise, and pregnancy. The comparisons of these settings of cardiac hypertrophy provide insight into pregnancy-associated cardiac adaptation. PMID:24448313

    Full Text Available Introduction. Cryoglobulins are single or mixed immunoglobulins that are subject to reversible precipitation at low temperatures. Objective. The aims of this paper were: 1. Comparison of cryoglobulin positive (CP, cryoglobulin negative (CN heroin addicts and the control group (CG in terms of serum immunoglobulins IgG, IgA and IgM and complement components C3 and C4; 2. Comparison of CP and CN heroin addicts in terms of rheumatoid factor (RF and circulating immune complexes (CIC; 3. Assessment of clinical manifestations in CP heroin addicts. Methods. This is a comparative study of cases (outpatients treated at the University Clinic of Toxicology in Skopje over 3.5 years, from January 2009 to June 2012. In this study 140 heroin addicts without HbsAg were examined, seronegative for HCV and HIV infections. They were divided into 2 groups: 70 CP and 70 CN heroin addicts. A previously designed self-administered questionnaire was used as a data source on participants. All heroin addicts underwent the following analyses: urea and creatinine in serum; creatinine in urine; proteinuria; 24-hour proteinuria; IgM, IgG, IgA, C3, C4 ; RF; CIC; creatinine clearance; ECG; toxicological analyses for opioids in a urine sample; cryoglobulins. In addition to these 2 groups, IgG, IgA, IgM, C3 and C4 were also examined in 70 healthy subjects (CG. Results. The study showed that there was no statistically significant difference between CP, CN heroin addicts and CG regarding the concentration of IgA, IgG, IgM, C3 and C4, and between CP and CN regarding the concentration of CIC. There was significant difference between CP and CN regarding the concentration of RF. The following conditions were significantly more frequently manifested in CP than in CN heroin addicts: arthralgia, Raynaud’s phenomenon, respiratory difficulties, neurological disorders, manifested skin changes, hematuria, 24-hour proteinuria levels, and decreased renal clearance. Conclusion. There were no

    Ultraviolet radiation (UVR)-induced skin cancers varies among organ transplant recipients (OTRs). To improve individual risk assessment of skin cancer, objectively quantified skin photodamage is needed. We measured personal UVR-exposure dose in OTRs and assessed the relation between individual UVR exposure, skin cancer and objectively measured photodamage in terms of skin autofluorescence, pigmentation, and black light-evaluated solar lentigines. Danish OTRs with (n=15) and without a history of skin cancer (n=15) kept sun diaries from May to September and wore personal dosimeters recording time-stamped UVR doses in standard erythema doses (SED). Photodamage was quantified as skin autofluorescence with excitation at 370nm (F370) and 430nm (F430), skin pigmentation (pigment protection factor, PPF), and black light-evaluated solar lentigines. OTRs with skin cancer received a higher UVR dose than OTRs without skin cancer (median 116 SED vs. 67 SED, p=0.07) and UVR exposure doses were correlated with increased PPF (p=0.052) and F370 on the shoulder (F370 shoulder ) (p=0.04). We found that skin cancer was associated with F370 shoulder (OR 10.53, CI 3.3-31,938; p=0.018) and time since transplantation (OR 1.34, CI 0.95-1.91, p=0.097). A cut-off at 7.2 arbitrary units, 89% of OTRs with skin cancer had F370 shoulder values above 7.2 arbitrary units and F370 shoulder was additionally related to patient age (p=0.09) and black light-evaluated solar lentigines (p=0.04). F370 autofluorescence indicates objectively measured photodamage and may be used for individual risk assessment of skin cancer development in OTRs. Copyright © 2017. Published by Elsevier B.V.

    Background Skin lesions are common manifestations in systemic lupus erythematosus (SLE). It is still unknown what the definite pathogenesis of skin involvement was and whether DNA participated in it. Our study was designed to explore the pathogenetic role and nature of nuclear antigen (DNA) deposited in the skin lesions of patients with SLE.Methods Thirty skin samples from patients with SLE and 2 normal skin samples were studied. Extracellular DNA was evaluated by indirect immunofluorescence methods. The deposited immune complexes were extracted by cryoprecipitation, and DNA was then isolated with phenol and chloroform. DNA fragment sizes were detected by agarose gel electrophoresis. Finally, 8 different probes were used to analyze the origin of these DNA molecules using Dot hybridization.Results Extracellular DNA staining was found only in skin lesions, mainly those located in the basement membrane zone, vascular wall, and hair follicle wall. Normal skin and non-lesion SLE skin showed no fluorescence at locations outside the nuclei. There were no differences in the rate and intensity of extracellular DNA staining when comparing active phase to remission phase patients. No relationship was found between extracellular DNA and circulating anti-dsDNA antibodies. Deposited DNA fragments clustered into four bands of somewhat discrete sizes: 20 000 bp, 1300 bp, 800-900 bp, 100-200 bp. Small sized fragments (100-200 bp) were positively correlated with disease activity (P<0.05, r=0.407). Dot hybridization showed significant homology of the various extracellular DNA fragments examined with human genomic DNA, but not with DNA from the microorganisms and viruses we examined. There were also homologies between DNA samples from different individuals.Conclusions DNA and its immune complexes may contribute to the pathogenesis of skin lesions in SLE. These DNA molecules range in size from 100 bp to 20 kb and may be endogenous in origin.

    2011-01-01

    Full Text Available The aim of this paper is to review the literature and identify orofacial manifestations of hematological diseases, with particular reference to anemias and disorders of hemostasis. A computerized literature search using MEDLINE was conducted for published articles on orofacial manifestations of hematological diseases, with emphasis on anemia. Mesh phrases used in the search were: oral diseases AND anaemia; orofacial diseases AND anaemia; orofacial lesions AND anaemia; orofacial manifestations AND disorders of haemostasis. The Boolean operator "AND" was used to combine and narrow the searches. Anemic disorders associated with orofacial signs and symptoms include iron deficiency anemia, Plummer-Vinson syndrome, megaloblastic anemia, sickle cell anemia, thalassaemia and aplastic anemia. The manifestations include conjunctiva and facial pallor, atrophic glossitis, angular stomatitis, dysphagia, magenta tongue, midfacial overgrowth, osteoclerosis, osteomyelitis and paraesthesia/anesthesia of the mental nerve. Orofacial petechiae, conjunctivae hemorrhage, nose-bleeding, spontaneous and post-traumatic gingival hemorrhage and prolonged post-extraction bleeding are common orofacial manifestations of inherited hemostatic disorders such as von Willebrand′s disease and hemophilia. A wide array of anemic and hemostatic disorders encountered in internal medicine has manifestations in the oral cavity and the facial region. Most of these manifestations are non-specific, but should alert the hematologist and the dental surgeon to the possibilities of a concurrent disease of hemopoiesis or hemostasis or a latent one that may subsequently manifest itself.

  14. Is skin penetration a determining factor in skin sensitization ...

    Science.gov (United States)

    Summary:Background. It is widely accepted that substances that cannot penetrate through the skin will not be sensitisers. Thresholds based on relevant physicochemical parameters such as a LogKow > 1 and a MW 1 is a true requirement for sensitisation.Methods. A large dataset of substances that had been evaluated for their skin sensitisation potential, together with measured LogKow values was compiled from the REACH database. The incidence of skin sensitisers relative to non-skin sensitisers below and above the LogKow = 1 threshold was evaluated. Results. 1482 substances with associated skin sensitisation outcomes and measured LogKow values were identified. 305 substances had a measured LogKow self-evident truth borne out from the widespread misconception that the ability to efficiently penetrate the stratum corneum is a key determinant of skin sensitisation potential and potency. Using the REACH data extracted to test out the validity of common assumptions in the skin sensitization AOP. Builds on trying to develop a proof of concept IATA

    Cardiovascular disease is the chief cause of death in technologically advanced countries and accounts for more than 50% of all deaths in the USA. For a patient with end-stage cardiac failure the only treatment presently available is organ replacement, either by transplantation or by the use of a mechanical heart. Transplantation has demonstrated its value: survival of more than 8 years and restoration of a normal quality of life to patients who were in end-stage cardiac decompensation. However, the prospect of routine clinical application of an artificial heart remains distant. The development of a totally implantable artificial heart still presents a series of challenging engineering problems with regard to strict constraints of size, weight, blood-material compatibility, adaptability of output to demand, efficiency and reliability of the power supply, and safety if nuclear fuel is used. The totally artificial heart is presently not an alternative to the cardiac allograft, but could provide short-term support for patients awaiting cardiac transplantation.

The objective of the current survey was to assess the occurrence of perceived "fragile skin" across different skin types in the general adult population. Methods: Individuals aged 15–65 years from five representative geographic regions (France, Spain, Sweden, Japan, and the US were interviewed and grouped into the following skin types: Caucasian North skin (n=1,218, Caucasian South skin (n=1,695, Asian skin (n=1,500, and Black skin (n=500. The main survey question was "In your opinion, do you have fragile skin?" Concepts relating to the nature and appearance of an individual's skin were also evaluated. Results: A total of 4,913 individuals were interviewed. Subjects in the Caucasian North, Caucasian South, Asian, and Black skin type groups responded positively to the question "In your opinion, do you have fragile skin?" in the following proportions: 24.44%, 29.71%, 52.67%, and 42.20%, respectively. With the exception of individuals in the Black skin group, "fragile skin" was prevalent in significantly more women than men (P<0.0001. Compared with other age categories, the prevalence of "fragile skin" was significantly higher in individuals aged 15–34 years (P<0.0001, regardless of skin type. In general, individuals reporting "fragile skin" were 2–3-fold more likely to respond positively to a series of questions relating to the nature and appearance of their skin. The prevalence of "fragile skin" was also higher in individuals who experienced dermatosis (skin lesions of any type in the previous 12 months. Conclusion: Whilst these

    There are two components of cardiac CT discussed in this article: coronary artery calcium scoring (CACS) and coronary computed tomography angiography (CCTA).The distinctive advantages of each CT examination are outlined. In order to ensure a successful cardiac CT program, it is imperative that imaging facilities market their cardiac CT practices effectively in order to gain a competitive advantage in this valuable market share. If patients receive quality care by competent individuals, they are more likely to recommend the facility's cardiac CT program. Satisfied patients will also be more willing to come back for any further testing.

    Skin graft is one of the most indispensable techniques in plastic surgery and dermatology. Skin grafts are used in a variety of clinical situations, such as traumatic wounds, defects after oncologic resection, burn reconstruction, scar contracture release, congenital skin deficiencies, hair restoration, vitiligo, and nipple-areola reconstruction. Skin grafts are generally avoided in the management of more complex wounds. Conditions with deep spaces and exposed bones normally require the use o...

    Full Text Available Context Preclinical and clinical research has shown that stem cell therapy is a promising therapeutic option for many diseases. This article describes skin stem cells sources and their therapeutic applications. Evidence Acquisition Compared with conventional methods, cell therapy reduces the surgical burden for patients because it is simple and less time-consuming. Skin cell therapy has been developed for variety of diseases. By isolation of the skin stem cell from the niche, in vitro expansion and transplantation of cells offers a surprising healing capacity profile. Results Stem cells located in skin cells have shown interesting properties such as plasticity, transdifferentiation, and specificity. Mesenchymal cells of the dermis, hypodermis, and other sources are currently being investigated to promote regeneration. Conclusions Because skin stem cells are highly accessible from autologous sources and their immunological profile is unique, they are ideal for therapeutic approaches. Optimization of administrative routes requires more investigation own to the lack of a standard protocol.
