Abstract The genus Malassezia currently includes seventeen species that have been isolated from healthy and diseased human and other animal skin. Malassezia are implicated in a range of cutaneous diseases in humans: pityriasis versicolor, atopic or seborrheic dermatitis, dandruff, folliculitis and psoriasis. The outbreak of the disease depends on the interaction between the host immune system and Malassezia species. Malassezia stimulates both the cellular and humoral immune response in humans. Although Malassezia species have been associated with various dermatological diseases in people, the detailed pathological role of Malassezia remains obscured. Malassezia yeasts require lipids for their growth and therefore to a greater extent they colonize the sites with more sebaceous glands. The ecosystem on skin is complex and its balance depends on several factors. The aim of this study was to determine the presence of Malassezia yeasts in clinically normal skin of 42 healthy, randomly selected individuals of different ages. In the group of people examined, up to 30 persons (71.4 %) represented by children, adults and the elderly were positive to Malassezia yeasts. It has been shown that the back is an area with a higher incidence (66.7 %) of observed yeast compared to the head (40.5 %).

Skin Biopsies

Background/Aims: This study examined the role of random normal skin biopsy in the diagnosis of intravascular lymphoma (IVL) in adult Western patients with clinically diagnosed hemophagocytic lymphohistiocytosis (HLH). Methods: In a retrospective chart review study, we analyzed a total of 59 skin biopsies that were performed to diagnose IVL in 21 adult patients with HLH seen at Stanford Hospital between 2004 and 2016. Results: Out of the 59 skin biopsies, 42 were taken from clinically normal-appearing skin and 17 from clinically abnormal-appearing skin. None of the 59 biopsies revealed a diagnosis of primary or metastatic malignancy, regardless of the malignancy history, clinical presentation, and biopsy and histopathologic characteristics. A review of 8 positive IVL cases at Stanford Hospital including 1 case associated with HLH showed 1 positive diagnosis by a targeted skin biopsy and other positive diagnoses by bone marrow (n = 4), lung (n = 2), brain (n = 2), muscle (n = 1), and nerve (n = 1). Conclusion: Random skin biopsies have a limited role in diagnosing IVL in adult patients with HLH, in the setting of a single academic institution in the USA. A review of the literature emphasizes the role of a full body skin exam with a selective skin biopsy in these patients.

В исследование были включены 50 женщин в возрасте 60,0±1,5 года, преподающих в течение 30±5,5 лет в среднем звене общеобразовательной школы (5-9-е классы) - основная группа, и 50 неработающих женщин 61,5±1,3 года - контрольная группа. Цель исследования - изучение роли витамина D в формировании иммунопатогенетических изменений со стороны клеточных и гуморальных иммунных факторов, процессов свободнорадикального окисления у работающих педагогов и неработающих женщин пожилого возраста и возможности коррекции выявленных нарушений дотацией витамина D . До начала исследования выявлено снижение суммарного содержания витамина D , нарушение функционально-метаболического статуса иммуноцитов, дисбаланс субпопуляционного состава лимфоцитов, продукции Тh 1/ Тh 2 цитокинов, повышение первичных и вторичных продуктов перекисного окисления липидного экстракта плазмы крови, снижение активности СОД и каталазы в основной и контрольной группах. Доказано наличие прямых корреляций содержания витамина D , баланса цитокинов, компонентов системы ПОЛ и антиоксидантной защиты. Дотация витамина D снизила тяжесть иммунных и оксидативных нарушений у обследуемых. Полученные результаты подтверждают необходимость мониторинга содержания витамина D для снижения риска развития иммунопатогенетических нарушений у лиц пожилого возраста. The study included 50 women aged 60±1,5 years, teaching for 30±5,5 years at the middle level of a secondary school (grades 5-9) - main group, and 50 non-working women 61,5±1,3 years. The purpose of the study was to study the role of vitamin D in the formation of immunopathogenetic changes from cellular and humoral immune factors, free radical oxidation processes in working teachers and unemployed elderly women and the possibility of correcting the revealed violations with vitamin D subsidy. Before the start of the study, a decrease in the total content of vitamin D was revealed , violation of the functional and metabolic status of immunocytes, an imbalance in the production of Th 1/ Th 2 cytokines, an increase in primary and secondary products peroxidation of the lipid extract of blood plasma, a decrease in the activity of superoxide dismutase and catalase to the main and control groups. The presence of direct correlations between the content of vitamin D , the balance of cytokines, the components of the lipid peroxidation system and antioxidant defense is proved. A vitamin D subsidy reduced the severity of immune and oxidative disorders in subjects. The obtained results confirm the need for monitoring the vitamin D content in order to reduce the risk of developing immunopathogenetic disorders in the elderly.

Abstract Background Seborrheic dermatitis (SD) is a subacute or chronic superficial inflammatory skin condition, characterized by pruritic, erythematous plaques with greasy, yellow-gray scales, which appear on areas rich in sebaceous glands such as the face, scalp, upper chest, and back. Aim of the Work To identify Malassezia species that are involved in the development of SD in different body sites (face, scalp and trunk) and in different age groups, by using Chrom agar. Patients and Methods Forty nine patients with seborrheic dermatitis attending dermatology outpatient clinic in Ain shams university hospital the samples collected from December 2018 to June 2019. Results In this study, the most affected areas were the scalp and other sites as face and ears, which is concordant with the majority of studies worldwide. The role of sex in propensity to the development of Malassezia spp. Infection in SD is still unclear. Conclusion The distribution of Malassezia spp. on healthy and diseased skin shows significant variation and differences, although our knowledge of Malassezia yeasts has increased tremendously during the last two decades, their pathological roles remain ambiguous, and there is currently no conclusive evidence that any given species is responsible for a specific disease.

download: Cancer is a serious problem throughout the world. The pathophysiology of cancer is multifactorial and is also related to gut microbiota. Intestinal microbes are the useful resident of the healthy human. They play various aspects of human health including nutritional biotransformation, flushing of the pathogens, toxin neutralization, immune response, and onco-suppression. Disruption in the interactions among the gut microbiota, intestinal epithelium, and the host immune system are associated with gastrointestinal disorders, neurodegenerative diseases, metabolic syndrome, and cancer. Probiotic bacteria (Lactobacillus spp., Bifidobacterium spp.) have been regarded as beneficial to health and shown to play a significant role in immunomodulation and displayed preventive role against obesity, diabetes, liver disease, inflammatory bowel disease, tumor progression, and cancer. Objective:: The involvement of gut microorganisms in cancer development and prevention has been recognized as a balancing factor. The events of dysbiosis emphasize metabolic disorder and carcinogenesis. The gut flora potentiates immunomodulation and minimizes the limitations of usual chemotherapy. The significant role of prebiotics and probiotics on the improvement of immunomodulation and antitumor properties has been considered. Methods:: I had reviewed the literature on the multidimensional activities of prebiotics and probiotics from the NCBI website database PubMed, Springer Nature, Science Direct (Elsevier), Google Scholar database to search relevant articles. Specifically, I had focused on the role of prebiotics and probiotics in immunomodulation and cancer prevention. Results:: Prebiotics are the nondigestible fermentable sugars that selectively influence the growth of probiotic organisms that exert immunomodulation over the cancerous growth. The oncostatic properties of bacteria are mediated through the recruitment of cytotoxic T cells, natural killer cells, and oxidative stress-induced apoptosis in the tumor microenvironment. Moreover, approaches have also been taken to use probiotics as an adjuvant in cancer therapy. Conclusion:: The present review has indicated that dysbiosis is the crucial factor in many pathological situations including cancer. Applications of prebiotics and probiotics exhibit the immune-surveillance as oncostatic effects. These events increase the possibilities of new therapeutic strategies for cancer prevention.

Abstract. Prospective Memory (PM; i.e., the ability to remember to perform planned tasks) represents a key proxy of healthy aging, as it relates to older adults’ everyday functioning, autonomy, and personal well-being. The current review illustrates how PM performance develops across the lifespan and how multiple cognitive and non-cognitive factors influence this trajectory. Further, a new, integrative framework is presented, detailing how those processes interplay in retrieving and executing delayed intentions. Specifically, while most previous models have focused on memory processes, the present model focuses on the role of executive functioning in PM and its development across the lifespan. Finally, a practical outlook is presented, suggesting how the current knowledge can be applied in geriatrics and geropsychology to promote healthy aging by maintaining prospective abilities in the elderly.

For many with heart failure, including the elderly and those with a preserved ejection fraction, both risk stratification and treatment are challenging. For these large populations and others there is increasing recognition of the role of cardiac fibrosis in the pathophysiology of heart failure. Galectin-3 is a novel biomarker of fibrosis and cardiac remodelling that represents an intriguing link between inflammation and fibrosis. In this article we review the biology of galectin-3, recent clinical research and its application in the management of heart failure patients.

Vasavaleha is one of the best medicine given for respiratory diseases. Corona viruses typically affect the respiratory system, causing symptoms such as coughing, fever and shortness of breath. It also affects host immune system of human body. Spreading rate of this disease is very high. Whole world is seeking for the treatment which can uproots this diseases. There in no vaccine available till date against this pandemic disease. Ayurveda mainly focuses on prevention of diseases alongwith its total cure. Rajyakshma Vyadhi is MadhyamMarga Roga as per Ayurveda. It shows many symptoms such as Kasa, Shwasa etc. By overall view of Covid 19, shows its resemblance with Rajyakshma Vyadhi described in Ayurveda. Vasavaleha is a Kalpa which is described in Rogadhikara of Rajyakshma. It shows Kasahara, Shwashara properties. It consists of Vasa, Pipalli, Madhu and Goghrita. These components shows actions like bronchodilation, antitussive effect and many more other actions. Pipalli shows important Rasayana effect. So in present review, we have tried to focus on role of Vasavaleha in the management of Covid 19. This can be used as preventive as well as adjuvant medication in treating Covid 19. There is need of further clinical research to rule of exact action of Vasavaleha against Covid 19.
