<b><i>Introduction:</i></b> Cutaneous defects involving the frontal region and anterior hairline of the scalp can result from congenital or acquired conditions. The negative esthetic impact can cause disturbances in the psychic and social sphere of the patient, causing problems in interpersonal relationships and in the body image itself. The use of skin expanders is usually effective in this region due to the bone base providing support and stability for its use. <b><i>Case Report:</i></b> We describe the case of a 64-year-old woman submitted to reconstruction of the anterior hairline of the scalp due to scar sequelae after coronal rhytidoplasty followed by pustular erosive dermatosis. We used tissue expansion (50 mL of saline per week until it reached 300 mL) and advancement flap. <b><i>Discussion/Conclusion:</i></b> Scalp reconstruction also includes vascularized soft tissue coverage, acceptable cosmetic appearance, and minimal morbidity for the donor area. The correction of scalp scars must obey 2 basic principles: tissue similarity and natural capillary pattern (direction, angle, capillary growth, and proper capillary line design). Tissue expansion and skin flap techniques can successfully correct defects in extensive scarring alopecia such as in the presented case.

This chapter describes the basic principles of toxicology and their application to occupational and environmental health. Topics covered include pathways that toxic substances may take from sources in the environment to molecular targets in the cells of the body where toxic effects occur. These pathways include routes of exposure, absorption into the body, distribution to organs and tissues, metabolism, storage, and excretion. The various types of toxicological endpoints are discussed, along with the concepts of dose-response relationships, threshold doses, and the basis of interindividual differences and interspecies differences in response to exposure to toxic substances. The diversity of cellular and molecular mechanisms of toxicity, including enzyme induction and inhibition, oxidative stress, mutagenesis, carcinogenesis, and teratogenesis, are discussed and the chapter concludes with examples of practical applications in clinical evaluation and in toxicity testing.

The body weight of U.S. adults and children has risen markedly over the past three decades. The physical health consequences of obesity are widely documented, and emerging research from the Midlife in the United States study and other large-scale surveys reveals the harmful impact of obesity on adults’ psychosocial and interpersonal well-being. This chapter synthesizes recent research on the psychosocial implications of body weight, with attention to explanatory mechanisms and subgroup differences in these patterns. A brief statistical portrait of body weight is provided, documenting rates and correlates of obesity, with a focus on race, gender, and socioeconomic status disparities. The consequences of body weight for three main outcomes are described: institutional and everyday discrimination, interpersonal relationships, and psychological well-being. The chapter concludes with a discussion of the ways that recent integrative health research on the psychosocial consequences of overweight and obesity inform our understanding of population health.

Objectives: Ear reconstruction is a challenging surgery for the complicated conditions in patients with microtia. The tissue expansion techniques were necessary and relatively safe for patients with insufficient soft tissue. However, complications such as necrosis of expanded flap and exposure of tissue expander limited the popularization of this method. This study described the use of modified Brent method to handle the exposure of the postauricular tissue expander. Methods: From January 2013 to December 2019, 27 ear reconstruction patients with trauma or necrosis on an expanded skin flap and subsequent exposure of tissue expander were treated with modified Brent method, which consisted of 3 stages: removal of the expander, tension-free closure of wound, and framework fabrication; elevation of reconstructed ear; lobule rotation; and minor modification. Results: Fifty-six percent of exposures occurred in the lower pole of the tissue expander. Exposure usually occurred 54.5 days after implantation. The majority of reconstructed ears had a satisfactory appearance and showed relatively stable outcomes. Only one case of cartilage exposure required revision surgery and was repaired by the temporoparietal fascia. Conclusion: With reasonable distribution of expanded flap, prolonged interval, and sutures under tension-free conditions, complications like the occurrence of trauma or necrosis-induced exposure of tissue expander can be repaired efficiently by a staging modified Brent method.

A 2-year-old male guinea pig (Cavia porcellus) presented with a pea-sized swelling on his right labium. The tumour was excised and reconstructive surgery was performed using a single pedicle advancement flap, leaving the bottom of the lip intact on account of it being essential for food apprehension and manipulation. Two parallel skin incisions were made in the rostrocaudal direction for almost half the length of the head and the resulting skin flap was carefully undermined, to avoid damaging the follicles and the muscles of the whiskers. The flap was carefully sutured over the excisional defect and at 1.5 months post-surgery, only a small residual scar remains. The lips are intact, the surgical site is covered with fur and many of the whiskers have regrown. Histopathology showed the excised mass to be a grade 1 soft tissue sarcoma, most likely a malignant peripheral nerve sheath tumour.

AbstractThis study concerns the development of autonomy in adult learners working on an online learning platform as part of a professional master's degree programme in “French as a Foreign Language”. Our goal was to identify the influence of reflective and collaborative dimensions on the construction of autonomy for online learners in this programme. The material used was 27 self-analysis papers in response to an assignment which asked students to review their distance learning experience (reflective dimension) and to highlight the role of others, if any, in their learning (collaborative dimension). In addition to these two major points, the analysis by category of the body of results shows principally that in qualitative terms, the factors of autonomisation for online learning are interconnected and include: the difficulties related to distance learning and the strategies that learners develop to face those difficulties, the importance of interpersonal relationships in social and emotional terms in overcoming those difficulties, the specific modes of sociability developed for distance learning and the related development of a new type of autonomy that is both individual and collective. The discussion examines the creation, over the course of time, of a new “distance learning culture” that is nonetheless never easy to create and share.

Alcohol abuse is a problem in South Africa and it has negative effects on the wellbeing of individuals, families, friends, work associates and neighbours. Alcohol produces both psychological and physical dependence. Gillies (1999:112) indicated that alcoholism usually interferes with the ability to socialize, work and may lead to much other destructive behaviour. It was further stated that people who are addicted to alcohol often have a low self-esteem, immaturity, are easily frustrated, and have difficulty in solving personal problems. This study investigated the perceptions of community members towards youth abusing alcohol and identified, among others, anti-social behaviour, poor interpersonal relationships, family disorganization, poor integration with family members and physical damage as the major concerns. An attempt was also made to develop strategies that can be used to overcome the problems of alcohol abuse by youth. Design and Method: A qualitative, exploratory, descriptive and contextual research design was followed in this study for the participants to describe their perceptions regarding the phenomenon in question (Brink, 2006:113). Data were collected through individual unstructured interviews in one village of the Capricorn District of the Limpopo Province. The researchers employed the principles of Guba and Lincoln (1993) cited in De Vos (1998:331) relating to trustworthiness and adhered to the ethical standards as set by the Democratic Nurses Association of South Africa (DENOSA, 1998:2.3.2).Findings: Five themes and seven categories emerged from the data analysis, using Tech’s open coding approach (1990), as outlined in De Vos (1998:343), namely, antisocial behaviour, poor interpersonal behaviour, physical damage, poor progress in life processes and effects of alcohol on the body. To address the problem of alcohol abuse by youth in one village (the study area) of the Capricorn District in the Limpopo Province and other villages the study recommends that educational and recreational facilities and the formation of youth structures should be established.

History Of

Acute poisoning by organophosphorus (OP) compounds is a major global clinical problem, withthousands of deaths occurring every year. Most of these pesticide poisoning and subsequentdeaths occur in developing countries following a deliberate self ingestion of the poison. Metacid(Methyl parathion) and Nuvan (Dichlorovos) are commonly ingested OP pesticides; Dimethoate,Profenofos, and Chlorpyrifos are other less frequently ingested compounds in Nepal. The toxicityof these OP pesticides is due to the irreversible inhibition of acetylcholinesterase (AChE) enzymeleading to accumulation of acetylcholine and subsequent over-activation of cholinergic receptorsin various parts of the body. Acutely, these patients present with cholinergic crisis; intermediatesyndrome and delayed polyneuropathy are other sequel of this form of poisoning. The diagnosisdepends on the history of exposure to these pesticides, characteristic manifestations of toxicityand improvements of the signs and symptoms after administration of atropine. The supportivetreatment of OP poisoning includes the same basic principles of management of any acutelypoisoned patient i.e., rapid initial management of airways, breathing, and circulation. Gastriclavage and activated charcoal are routinely used decontamination procedures, but their valuehas not been conclusively proven in this poisoning. Atropine is the mainstay of therapy, andcan reverse the life threatening features of this acute poisoning. However, there are no clearcut guidelines on the dose and duration of atropine therapy in OP poisoning. Cholinesterasereactivators, by regenerating AChE, can reverse both the nicotinic and muscarinic effects;however, this benefit has not been translated well in clinical trials. All these facts highlight thatthere are many unanswered questions and controversies in the management of OP poisoningand there is an urgent need for research on this aspect of this common and deadly poisoning.Key Words: poisoning, organophosphorus insecticides, decontamination, antidotes

The scientific article considers the issues of corporate social responsibility management. The main approaches to evaluating the effectiveness of the implementation of corporate social responsibility measures are considered and the basic principles of evaluating the corporate social responsibility management system are determined. The basic principles of evaluation of the system of corporate social responsibility of the enterprise are analyzed, the main ones of which are: universality, predominance of performance indicators rather than efficiency, differentiation of indicators of external and internal environments instruments of strategic benchmarking in the social sphere in certain areas, such as training and development of employees, charity and sponsorship. A system of types of organizational profile is proposed in assessing the balance of corporate social responsibility management system, which takes into account the assessment of retrospective indicators, assessing the current state of corporate social responsibility and assessing the prospects of corporate social responsibility. The criteria for assessing the accumulated organizational experience in the field of corporate social responsibility and social investment, the criteria for assessing the current state of the corporate social responsibility system, the criteria for assessing the prospects for the development of the corporate social responsibility system are studied. The scheme of determining the type of organizational profile in assessing the balance of the corporate social responsibility system of the company and the system of four types: dynamic, indicates the company’s intention to make the area of corporate social responsibility a strategic factor of competitiveness; a balanced type of profile, which at a relatively high level of individual assessments speaks of a balanced social policy and successful practice of social investment; regressive profile, which signals to management that in the future the company may lose the benefits of sustainable development related to the social sphere and special attention should be paid to investment policy, risk assessment of social investment and balanced development of intellectual and social capital and the inertial profile reflects the complete absence of any CSR planning in the company.

And Behavior

Ayurveda is the oldest science of health care, explaining both the perspectives, i.e., prevention and cure of diseases. The fundamental principles of Ayurveda explore life’s philosophy, including the entire cosmos having five significant elements (Akash, Vayu, Agni, Jala, and Prithvi) establishing the Prakruti, i.e., a unique combination of physiological and psychological characteristics in a human being. In Ayurveda, Ahara (Diet), and Vihar (Exercise/Movements), fundamental pillars are thoroughly explained according to a specific Prakruti, which denotes personalized medicine in the present era. Diet is the essential factor that comprises the five significant elements with six rasas (Sweet, Sour, Saline, Pungent, Bitter, Astringent). Each Rasa has its specific nutritional properties helpful for the maintenance of health. Moreover, it also prevents diseases and plays a vital role in the restoration of health from disease conditions. The appropriate diet plan is essential in the pandemic situation because the digestive power (Agni) becomes hampered due to faulty lifestyle and unwholesome food habits that result in vitiation of three bio-humors (Vata, Pitta, Kapha) in the body. According to Ayurveda’s basic principles, weakened digestive power is the main culprit for forming various diseases. Therefore, it is highly imperative to select a suitable diet and behavioral regimes during pandemic situations.

Thermography is a technique of measurement of skin temperature distribution on the body over a given period of time. It is a noncontact, noninvasive method that utilizes the heat from an object to detect, display, and record thermal patterns and temperature across the surface of the object. Over the years, various devices have been used to measure the amount of heat dissipated by the body and most recently thermography has been emerged to detect the oral and maxillofacial pathologies. It is used to detect malignancies of the maxillofacial region such as vitality of teeth, TMJ disorders, chronic orofacial pain, assessing inferior alveolar nerve decit, and detection of herpes labialis. The present article highlights the history, basic principles, types and applications of thermography and its benecial role in detecting the maxillofacial pathologies in dentistry.
