Nodular melanoma in a 53-year-old male with glioblastoma multiforme: A rare case report

@#Although melanoma only accounts for 1% of skin cancers, it is responsible for most skin cancer deaths. Glioblastoma multiforme, a high-grade astrocytoma, is the most aggressive and devastating primary brain tumor. These two diseases remain to be the biggest therapeutic challenge in both specialties of dermatology and neuro-oncology. A 53-year-old Filipino male who presented with a 2-year history of generalized dark brown and black patches on the body developed weakness and numbness of the left extremities. Biopsy and immunohistochemical staining of the skin revealed nodular melanoma with adjacent regressing melanoma. Biopsy of the intracranial mass showed glioblastoma multiforme. One month after the partial excision of the intracranial mass, the patient expired due to brain herniation. Nodular melanoma and glioblastoma multiforme may occur concomitantly in a patient. A review of the literature suggests a shared genetic predisposition. Its existence carries a poor prognosis and requires early detection to start aggressive treatment.

A case of a 62-year-old male with Actinomycetoma successfully treated using combined medical and surgical therapy

INTRODUCTION@#Actinomycetoma is a neglected infectious disease that presents with a triad of subcutaneous mass, with sinus formation and seropurulent discharge containing grains. This causes severe functional disability to patients if not treated early and properly.@*CASE REPORT@#We report a case of a 62-year-old adult Filipino farmer diagnosed with actinomycetoma of the left foot. For 8 years, the patient medicated with several antibiotic therapies affording minimal improvement of symptoms. Hence, surgical intervention with combination antimicrobial therapy was done which provided resolution of symptoms, improving the quality of life of the patient.@*CONCLUSION@#Treatment of actinomycetoma must be individualized among patients. Although oral antibiotics became the standard of treatment, combining surgical treatment with oral medications may be considered to ensure effective management of the disease.

Teleconsulta médica. Análisis y recomendaciones del Departamento de Ética del Colegio Médico de Chile / Medical teleconsultation. Analysis and recommendations from the ethics department of the Chilean medical association

The possibility of allowing patients access to health professionals, has been greatly facilitated by advances in technology. Indeed, nowadays it is possible not only direct contact between one health professional with another, but also the possibility of sending images and other tests to consult distant colleagues. This has undoubtedly enabled better health care for many patients. It is also possible for a patient to consult a doctor directly in a remote and synchronous way with oral and visual contact, thus establishing a new form of medical consultation. It is this last way of relationship, which has already spread as a practice in normal times, which arouses apprehensions about the ethical requirements that a consultation must meet. This work by the Ethics Department of the Chilean Medical Association seeks to reflect on the ethical demands of a medical consultation and on the shortcomings that teleconsultation has. It also aims to propose several recommendations, so that this new form of doctor-patient relationship serves as a complement to traditional care, without jeopardizing the objectives of a medical action.

Argumentos éticos a favor y en contra de la participación del profesional médico en la muerte asistida. Análisis del Departamento de Ética del Colegio Médico de Chile / Ethical arguments for and against the participation of the medical profession in assisted death: analysis of the Ethics Department of the Chilean Medical Association

The discussion of a bill that allows medically assisted death (MAD) in Chile, revived the debate about the ethics of this practice. The Department of Ethics of the Chilean Medical Association herein analyzes arguments in favor or against the participation of the medical profession in MAD. Among the main arguments against the participation of physicians in this practice are that MAD conflicts with the basic ethical principles of medical practice, that it is contrary to the purposes of medicine and that it could erode the patients' and society's confidence in physicians. The arguments in favor are related to physician´s compassion and non-abandonment of patients during their illness, choosing palliative care and ushering them to the final instance. Additionally, there is social expectation that this practice will be carried out by trained physicians who can verify that the strict criteria established by the legislation are met, guarantee that it obeys to a repeated request of a fully capable patient, and who is able to deal with the complications of the procedure. In this document we aimed to represent the different perspectives about physicians' participation in MAD, offering arguments to colleagues and stimulating their participation in this important debate.

Toma de decisiones en hemodiálisis crónica: estudio cualitativo en adultos mayores / Decision making among older adults in hemodialysis. A qualitative assessment

Background: In Chile there are 22,310 people in Chronic Hemodialysis (CHD), 53% of them older adults (OA). Shared decision-making and advance directives (AD) are especially important in OA with end-stage chronic renal failure, since they have greater levels of disability, morbidity and mortality, raising doubts about the benefit of therapy. Aims: To understand the experience in decision making and explore ways to express AD, in OA in CHD. Material and Methods: A qualitative phenomenological study, performing 12 in-depth interviews to OA who had been at CHD for at least one year. Results: The analysis revealed four broad comprehensive categories, two related to participation in the decision to enter CHD, namely the experience of subjects as spectators and their lack of interest for decision support and two referred to the expression of AD, namely the difficulty in facing their own finitude and resistance to express AD. Conclusions: There is little participation of older adults in the decision about their admission to dialysis therapy, and once they enter the CHD program they are not prepared to discuss AD in general, nor an eventual suspension of dialysis in particular.

La objeción de conciencia en la educación médica. Una propuesta para Chile / Conscientious objectors in Chilean medical education

The Chilean Law regulating the voluntary interruption of pregnancy, contemplates the possibility that health personnel may refrain from doing the procedure if they have stated that they are conscientious objectors (CO). There are numerous articles on the subject. However, the impact on medical training centers when a student or resident abstain from performing certain clinical procedures invoking CO, has seldom been analyzed. In this article, we explore the rights and duties of the CO students to perform an abortion or other clinical procedures for either religious or cultural reasons. Based on international experience, we recommend that all health care centers should have established and publicly known policies on this matter. Finally, we honor CO invoked by students, based on three general principles. First, the autonomy and moral integrity of the students should be respected. Second, an adequate ethical sensitivity is promoted. Third, it contributes to the necessary heterogeneity and diversity of students, promoting a desirable pluralism. However, certain interests and values, such as the well-being of patients, must be considered over and above accepting the CO requests.

Aspectos éticos de la conducta del médico ante personas en huelga de hambre: opinión del Departamento de Ética del Colegio Médico de Chile / Ethical aspects of the doctors' behavior towards people on hunger strike: position paper from the Ethics Department of the Chilean Medical Association

Every so often, in Chile there is a discussion about the role of physicians in the care of people on hunger strike (HS). In this document, we review the ethical aspects of health care for persons in HS, aiming to provide guidelines to medical doctors who are required to attend them. First, we make an important distinction between HS and suicide, since the former is used as a protest and denunciation tool, while suicide seeks deliberately to end a life. Then we describe the three roles that the health professional can fulfill: as a treating doctor, as an expert or as an official of a prison. The respect for the autonomy and dignity of the person in HS must prevail whatever the role of the physician. Therefore, we maintain that under no circumstances, people who have autonomously decided to be in HS should be fed by force. Due to the complexity of the issue, we make special considerations about the management of minors and the non-competent persons in HS. In conclusion, we adhere to the principles that inspire the Declaration of Malta, which indicate that it would be preferable to "allow a person on hunger strike to die in dignity, rather than subjecting them to repeated interventions against their will".

Experiencia en el Foro Global de Bioética en Investigación: desafíos para la revisión ética en Chile / Experience in the global forum of bioethics in research: challenges for the ethical review in Chile

The Global Forum on Bioethics in Research annually convenes a number of researchers, bioethicists and stakeholders with a shared interest in the ethics of conducting research in low and middle-income countries (LMIC). It provides a useful platform to discuss ethical issues that affect research practice in different scenarios, promoting ethically conducted research, global development for health research ethics and partnerships between the global north and south. As participant of the last three meetings, in this article the author analyzes the main ethical issues that were discussed in this forum, namely "Emerging epidemic infections and experimental medical treatments" (Annecy, France, 2015); "Ethics of research in pregnancy" (Buenos Aires, Argentina, 2016), and "The ethics of alternative clinical trial designs and methods in LMIC research" (Bangkok, Thailand, 2017). Local research ethics committees are not well prepared to face the new ethical challenges associated with research conducted in emergency situations or in pregnant women, or to evaluate new methods, such as alternative clinical trial designs (cluster randomized trials, adaptive platforms, or controlled human infection models, among others). According to this scenario, research ethics committees should be trained to carefully assess the risks and benefits of approving this type of research. In this context, it is necessary to harmonize local regulations with the new international standards in research ethics.

Percepciones y creencias sobre criopreservación embrionaria en mujeres y hombres que se realizan técnicas de reproducción asistida en Santiago, Chile / Perceptions and beliefs about embryo cryopreservation in women and men who have assisted reproductive techniques in Santiago, Chile

RESUMEN Introducción y objetivos: Aunque la criopreservación embrionaria es frecuentemente utilizada como parte de las técnicas de reproducción asistida, no existe información cuantitativa de cómo las parejas infértiles viven la experiencia de tener embriones criopreservados en Chile. El objetivo del estudio fue examinar las percepciones y creencias que tienen mujeres y hombres respecto de sus embriones criopreservados, sus perspectivas respecto de la donación reproductiva y destino de los embriones remanentes. Metodología: 153 mujeres y hombres con embriones criopreservados provenientes de un hospital público, Instituto de Investigaciones Materno Infantil y un centro privado, Clínica Las Condes, en Santiago, Chile, respondieron durante mayo 2015 a mayo 2016 un cuestionario en línea, anónimo, respecto de sus percepciones y creencias sobre criopreservación embrionaria. Resultados: Los encuestados reconocen a sus embriones criopreservados como un hijo (53.2%) o un proyecto de hijo (40.7%). Sólo 8% los considera un grupo organizado de células; sobre el 60% rechaza la opción de descartarlos o usarlos para investigación. Los participantes del hospital público tenían mayor disposición a donar sus embriones remanentes a otras parejas que aquellos del privado (61% vs 40%; P=0.016). Un 34% de las personas encuestadas estuvo de acuerdo con donar embriones a parejas de un mismo sexo. Conclusión: Este estudio muestra que las personas chilenas tienen un vínculo emocional con sus embriones criopreservados y no consideran descartarlos. Los resultados de este estudio pueden servir para dar adecuada consejería a las personas que se realizan técnicas de reproducción asistida, de tal modo de tomar decisiones informadas respecto de la criopreservación.

ABSTRACT Background and objetive: Although embryo cryopreservation is frequently used as part of assisted reproductive technology, quantitave information addressing how infertile couples live the experience of having cryopreserved embryos is lacking in Chile. The aim of this study is to examine men and women's perception and beliefs regarding their cryopreserved embryos, as well as their perspective on embryo donation and disposition. Methods: 153 women and men with frozen embryos from a public hospital, Instituto de Investigactiones Materno Infantil, and a private clinic, Clínica Las Condes, in Santiago, Chile, responded between May 2015 and May 2016 to an anonymous online survey addressing their perceptions and beliefs concerning their cryopreserved embryos. Results: Respondents considered their frozen embryos to be equivalent to a child (53.2%) or a potential child (40.7%). Only 8% regard them as an organized group of cells. Over 60% of respondents disagree with destroying surplus embryos or using them for research. Participants from the public hospital are more willing to donate their embryos to another couple than those from the private center (61% vs 40%; P=0.016); 34% of respondents agreed to donate surplus embryos to same sex couples. Conclusion: This study reveals that Chilean couples are emotionally bound to their frozen embryos, and that discarding them is not an option. The results from this survey will help strengthen counseling for couples to enable them to make informed decisions regarding their surplus embryos.

Dermatoglyphic Pattern Differences in Females with Reproductive System Cancers and It’s Scope in Preventive Care

Introduction: Female reproductive system cancers shorten lifespan in women because of high mortality and morbidity. The detection of pre-invasive and micro-invasive stages makes near 100% survival of cancer patients. Dermatoglyphics is the scientific study of fingerprints. Many genes which take part in the control of finger and palm dermatoglyphic development distinguished cancer patients from the general population. It is possible that these genes also predispose to the development of malignancy. Since many investigations are needed to confirm the diagnosis of cancers, dermatoglyphics can be used as a screening procedure for planning preventive care if a specific pattern is known for a cancer. Aims and Objectives: To analyze the prints of different cancers, to analyze the results, compare with controls and observe the differences in main parameters of dermatoglyphic patterns and to determine a specific pattern for specific cancers. Subjects and Methods: This is a prospective, observational and an analytical study started after the approval by Institutional Ethical Committee of S.V. Medical College, Tirupati. The material for the study consisted of finger and palm prints of outpatients and inpatients of the Department of OBG, Tirupati, Cancer Hospital in and around Tirupati, Nellore and Kadapa. The ink prints of each finger and palm were collected and analyzed. Results: Ridge counts, digital patterns and main line formulae observed in different cancers in the present study were analyzed and presented. Mean TFRC was higher in normal group. Greater AFRC was observed in cancer cervix patients when compared to controls. In the present study, there is no difference (p> 0.05) in a-b ridge count among carcinoma of cervix and control group in both hands. Differences of mean atd, tad and tda angles among the groups are not statistically significant (P>0.05).The most common C-main line termination pattern of cancers are U followed by R and then Ab. IV interdigital area of both hands presented less incidence of loop pattern in cancer cases when compared to normal group. Special findings in respective cancers are discussed separately and they are not found in any other literature. Conclusion: There are very limited studies in literature on dermatoglyphic pattern in female reproductive cancers. Though the cost of prints is less, more time and skilled human resources are required for their analysis. Study sample size of controls and cases to be increased. Public should be enlightened about dermatoglyphics. If large number of studies are done and a specific pattern is established for specific cancers, then it becomes cost-effective to people so that a risk is predicted beforehand in any disease and preventive methods can be employed at an early age as the dermatoglyphic patterns do not change in a life time.

Formas de Revisión Ética de Proyectos de Investigación Biomédica / Differentiated review of biomedical research projects by ethics committees

Ten years after the approval of the Chilean bill that regulates scientific research in humans (Law Nº 20.120), and considering the current status of accreditation and training of many Research Ethics Committee (REC), it is necessary to analyze their performance. We analyzed the Chilean experience with REC aiming to propose a differential type of review, considering the risks to research participants. To improve the quality of the review and the efficiency of these committees, we propose to differentiate the revisions depending on the type of project, its methods and its risks. Initially, the types of review should be classified as exempt from review, expedited review and full review by the committee. In this proposal the type of review is confirmed or can be modified by a designated member of the committee after an initial review of the project. Thus, the deliberation and review times of the committee could be optimized avoiding delays in their revision.

Conflictos éticos en las autorías de trabajos científicos / Ethical conflicts in the authorship of scientific papers

The frequency of conflicts about authorship of publications has increased along with the increase in the number of people involved in scientific work. Some of the factors that strongly influence the generation of conflicts and malpractices in authorship definition of scientific publications are the pressure of academia, economic incentives from the pharmaceutical industry in the field of biomedicine and authors’ wishes and expectations of recognition, among other factors. The article analyzes this problem, increasingly common in the field of medicine and related areas. Special attention is devoted to the prevailing laws in our country and international guidelines related to intellectual property and authorship of scientific publications, respectively. However, the ethical commitment, intellectual honesty and truthfulness of each of the authors about what is reported seems to be the decisive factor for the solution to these authorship conflicts.

Dilemas éticos acerca de la revelación de errores médicos a los pacientes

Since the publication of the Institute of Medicines report “To Err is Human: Building a Safer Health System” awareness of the importance of medical errors has increased. These are a major cause of morbidity and mortality and recent studies suggest that they can be the third leading cause of death in the United States. Difficulties have been identified by health personnel to prevent, detect and disclose to patients the occurrence of a medical error, an also to report them to the appropriate authorities. Although human error cannot be eliminated, it is possible to design safety systems to mitigate their frequency and consequences. Our goal is to provide an update on the major concepts related to medical errors, a review of Chilean legislation on the subject, and a bioethical analysis on the principles involved, along with a management proposal. We propose mandatory reporting of errors to the health institution where they occur, to serve as a measure of personal and team learning, and to disclose the error to patients, depending on their own preferences.
