Pleasant parosmia with regard to own stool after SARS-CoV-2 infection.

Coronavirus disease 2019 (COVID-19) has had a significant global impact due to the millions of deaths it has caused secondary to respiratory failure. However, the disease has also been associated with a wide array of manifestations in other organ systems. Among them, the presence of anosmia, which occurs in up to half the patients, has become a new sign of alarm to suspect the infection. Although up to 90% of affected patients will experience an improvement of their olfactory alterations within a month after the infection, the variety and severity of olfactory disturbances clearly cannot be summarized by the dichotomy of having anosmia or not. Parosmias are a type of olfactory dysfunction characterized by altered perception of odors, which can reflect both damage at some level of the olfactory tract, as well as the possibility of reversibility of said damage. The present manuscript describes possible olfactory disturbances associated with COVID-19, their pathophysiology, and potential clinical significance.

La enfermedad por coronavirus 2019 (COVID-19) ha tenido un impacto mundial trascendente por los millones de muertes que ha causado secundarias a insuficiencia respiratoria. Sin embargo, la enfermedad también se ha asociado a una amplia gama de manifestaciones en otros sistemas. Entre ellas, la presencia de anosmia, la cual ocurre en hasta mitad de los pacientes, se ha vuelto un nuevo dato de alarma para sospechar la infección. Aunque hasta el 90% de los pacientes afectados presentarán mejoría de sus alteraciones olfatorias dentro del mes posterior a su cuadro, la variedad y gravedad de alteraciones olfatorias claramente no pueden resumirse en la dicotomía de tener o no anosmia. Las parosmias son un tipo de alteración olfatoria caracterizadas por percepciones alteradas de los olores, las cuales pueden reflejar tanto daño a algún nivel del tracto olfatorio, así como la posibilidad de reversibilidad de dicho daño. En el presente manuscrito se describen las posibles alteraciones olfatorias asociadas a COVID-19, su fisiopatología, y potencial significancia clínica.

Valoración preoperatoria en cirugía no cardiaca: un abordaje por pasos.

Preoperative assessment in non-cardiac surgery is essential to reducing the rate of in-hospital complications. Its purpose is to identify patients with higher levels of risk. Preoperative assessment should not be restricted to cardiovascular aspects, but it should focus on all organs and systems and include medication reconciliation. The purpose of this article is to approach the performance of a preoperative assessment in non-cardiac surgery from the perspective of the internist, with the purpose to help prevent adverse events and improve the overall outcome.

El objetivo de este escrito es abordar la realización de una valoración preoperatoria en cirugía no cardiaca desde la perspectiva del médico internista, con el fin de ayudar a prevenir eventos adversos y mejorar el desenlace general.

[Successful home-made fecal transplant for an elderly woman]. / Trasplante fecal domiciliario en una mujer de la tercera edad.

Recurrent clostridium difficile infection (CDI) is a challenge for infectious disease specialists. A third of first recurrences will fail antibiotic therapy. Several mechanisms have been proposed to explain this, such as persistence of spores, inadequate antibody response, and altered gut microbiota. Standard recommendations for CDI treatment include metronidazole and vancomycin. Fecal transplant has proven to be an effective therapy for recurrent CDI. Infusion of stools can be administered to the upper or lower gastrointestinal tract during an endoscopic procedure or using nasogastric/duodenal or rectal tubes. Elderly persons have an increased incidence of recurrent infection and have a higher mortality rate. We propose a home-based delivery method using a 5 ml syringe for intrarectal infusion of stools.

Hepatic steatosis as an independent risk factor for severe disease in patients with COVID-19: A computed tomography study.

Background and Aim: Hepatic steatosis (HS) is associated with diabetes, hypertension, and obesity, comorbidities recently related to COVID-19 severity. Here, we assessed if tomographic HS is also a risk factor for severe COVID-19 pneumonia. Methods: We included 213 patients with a positive real time polymerase chain reaction (RT-PCR) test and chest computed tomography (CT) from an out-hospital facility and a hospital. We obtained information on demographics; weight; height; smoking history; diabetes; hypertension; and cardiovascular, lung, and renal disease. Two radiologists scored the CO-RADs system (COVID-19 Reporting and Data System) (1 = normal, 2 = inconsistent, 3-4 = indeterminate, and 5 = typical findings) and the chest CT severity index (≥20 of 40 was considered severe disease). They evaluated the liver-to-spleen ratio (CTL/S) and defined tomographic steatosis as a CTL/S index ≤0.9. We used descriptive statistics, χ2 and t student tests, logistic regression, and reported odds ratio (OR) with 95% confidence interval (CI). Results: Of the patients, 61% were men, with a mean age of 51.2 years, 48.3% were CO-RADs 1 and 51.7% CO-RADs 2-5. Severe tomographic disease was present in 103 patients (48.4%), all CO-RADs 5. This group was older; mostly men; and with a higher prevalence of obesity, hypertension, diabetes, and HS (69.9 vs 29%). On multivariate analysis, age (OR 1.058, 95% CI 1.03-1.086, P < 0.0001), male gender (OR 1.9, 95% CI 1.03-3.8, P = 0.04), and HS (OR 4.9, 95% CI 2.4-9.7, P < 0.0001) remained associated. Conclusion: HS was independently associated with severe COVID pneumonia. The physiopathological explanation of this finding remains to be elucidated. CTL/S should be routinely measured in thoracic CT scans in patients with COVID-19 pneumonia.

[Social capital, poverty and self-perception of family support in cases of acute respiratory illness]. / Capital social, pobreza familiar y autopercepción de apoyo en casos de enfermedad respiratoria aguda.

The aim of this study was to correlate the socio structural variables of the Simplified Index of Family Poverty with the self-perception of resources that conform social capital among patients with acute respiratory disease (ARD). We used a qualitative and quantitative methodology. The sample included 848 cases distributed in seven Rural Medicine Units of Mexico. We considered three pathways described by Kawachi where social capital might have an impact on individual health. The bivariate correlation and discriminant analysis showed that when there is evidence of poverty in the family, the statistically significant differences are mainly observed in self-perception. Moral support of sons and daughters is thereby increased when there is an ARD. We concluded that when there is a higher index of family poverty there is a decreased access to social resources when a family member is diagnosed with an ARD.

[Pneumonia and its social representations]. / La neumonía y sus representaciones sociales.

OBJECTIVE: To correlate the sociostructural variables with the knowledge about pneumonia and to explore the social representations about the etiology, prevention, development and treatment in poor communities. METHODS: A survey in 848 adults from seven Rural Health Centers affiliated to IMSS-Oportunidades Program in four States, was carried out. RESULTS: One-third of the sample did not understand the term pneumonia; 35 % of the patients with risk factors did not know its etiology; 43 % did not know about associated complications but 85 % considered that it causes death. The use of antibiotics was recognized as a therapeutic measure by 78 % and 20 % did not know how to prevent pneumonia. CONCLUSION: The findings showed a positive attitude to immunization but inadequate information about respiratory diseases. In neighborhoods with insufficient public services (purified water, electricity and paved roads) the ignorance about pneumonia tended to increase.

[Recurrent pericardial effusion due to familiar Mediterranean fever]. / Pericarditis recidivante y fiebre mediterránea familiar.

Pericarditis is usually a complication of viral or bacterial infection. In addition, it can be associated to systemic diseases such as autoimmune disorders, rheumatic fever, cancer, tuberculosis and AIDS. It can also be related to familial Mediterranean fever, an autosomic recessive inflammatory disease, characterized by fever, abdominal pain, and pleuritis mainly seen in persons from the Mediterranean area. In this study, we described the evolution and treatment response to colchicine in three patients with pericarditis associated to familial Mediterranean fever. Two of the patients had a pericardiectomy showing in their biopsy nonspecified inflammatory changes. Later their diagnosis were confirmed by genetic markers, echocardiogram and EKG. They were treated with antiviral and antibiotics without any improvement; subsequently they had good results with colchicine.

[Urinary incontinence in the elderly]. / Incontinencia urinaria en el adulto mayor.

Urinary Incontinence (UI) is a cardinal geriatric syndrome that has an impact on the health and quality of life of the elderly and those living around them. The etiology is often multifactorial. Physical, cognitive, functional, and psychological factors contribute to the appearance of UI. In most patients, the clinical history and a good physical examination are enough to diagnose UI accurately; although to confirm and classify UI further more complex tests are needed. The fields of pharmacology, endoscopy, neurophysiology, and surgery are making significant progress to manage UI; therefore, is useful for all practicing physicians that attend elderly patients to learn about the new therapeutic options.

[Perioperative evaluation in elderly patients]. / Valoración perioperatoria en el anciano.

With the multiple advances in the field of medicine and the resulting increase in life expectancy, the population pyramid is showing a tendency towards inversion; each day it becomes more feasible to surgically treat elderly patients. These patients represent a challenge not only because of the comorbidity that generally is associated with the elderly patient, but because of the multiple endemic physiological changes that alter and usually diminish their ability to cope with stressful situations. The elderly also experience social, economic and motivational problems during their illnesses, which should be considered during the surgical period in order to optimize the results of surgery and contribute to improve the quality of life of our patients. The approach with patients >65 years of age during the perioperative period should be multifactorial. It is necessary to acknowledge the physiological changes, poly-pathology, poly-pharmaceutical, and social situation of our elderly patients since these are factors that will determine their response to, and recuperation from, the surgical treatment.

[Cerebral venous thrombosis in systemic lupus erythematosus. Case report and literature review]. / Trombosis venosa cerebral en lupus eritematoso sistémico. Informe de un caso y revisión de la literatura.

We reviewed a case of cerebral venous thrombosis as the manifestation of systemic lupus erythematosus in a 27-year-old woman whose main symptom was headache, and in which subarachnoid hemorrhage was initially suspected. The angiography revealed thrombosis in the superior longitudinal sinus. The treatment with steroids was satisfactory, with complete resolution of symptoms. We also reviewed the reported cases in medical literature.

[Insomnia. A severe health care problem]. / Insomnio. Un grave problema de salud pública.

The magnitude which sleep has on personal well-being is similar to the effects of diet and exercise. Sleep deprivation has severe negative effects on an individual's overall health, and this is usually overseen. From 30 to 40 % of the population has presented insomnia at a certain moment of life and from 9 to 15 % have evolved into a chronic and severe insomnia. Recent investigations have related sleep deprivation with obesity, metabolic disorders, heart disease, mental health problems and dementia. Recently, more investigations have focused on the multiple alterations suffered by the immune system in cases of sleep deprivation. In order to make an opportune diagnosis of insomnia, it is vital to obtain a detailed history of the patients' sleep habits. In the physical exam one must search for signs and symptoms which might suggest an organic cause that generates the patient's insomnia. One of the pillars in treatment of these patients consists in acquiring an adequate sleep hygiene based on the optimization of the environment and the behavior that are associated with sleep.

La magnitud que tiene el sueño en el bienestar integral de una persona es similar a los efectos de la dieta y el ejercicio. La privación del sueño tiene efectos deletéreos graves en la salud del individuo y por lo general estos son ignorados. Entre un 30 y un 40 % de la población ha presentado insomnio en algún momento de su vida y del 9 al 15 % ha desarrollado insomnio crónico grave. Diversos estudios vinculan la falta de sueño con obesidad, enfermedades metabólicas, problemas cardiacos, desórdenes psiquiátricos y demencia. Existen actualmente grupos que se enfocan en las alteraciones en la respuesta inmune que genera la falta de sueño. Para realizar un diagnóstico oportuno de insomnio, es indispensable que durante la consulta se obtenga una historia clínica detallada de los hábitos del sueño. En la exploración física se debe enfatizar la búsqueda de signos y síntomas que sugieran una causa orgánica específica que contribuya a la alteración del sueño. Uno de los pilares del tratamiento es establecer en todos los pacientes una buena higiene del sueño con base en la optimización del ambiente y de las conductas asociadas con el mismo.

[West Nile fever]. / Fiebre del Nilo Oeste.

West Nile fever is a mosquito-borne febrile illness seen in Africa, Asia, and Europe, but reported in North America only once. West Nile virus is of the family Flaviviridae, genus Flavivirus. Several West Nile fever outbreaks were reported from Israel in the 1950s and in 1980. Since the mid-1990s, frequency and apparent clinical severity of West Nile virus outbreaks have increased. Outbreaks in Rumania (1996), Russia (1999), and Israel (2000) involved hundreds of persons with severe neurologic disease. In the summer of 1999, West Nile virus was recognized in the among Western Hemisphere for the first time when it caused an epidemic of encephalitis and aseptic meningitis among residents of greater New York City. Other outbreak occurred during the summer of 2000. West Nile fever in humans usually is a febrile, influenza-like illness characterized by abrupt onset. Occasionally (less than 15% of cases) are acute aseptic meningitis or encephalitis. Although human vaccines for West Nile virus are under development, the most effective to way reduce local population of mosquitoes is to eliminate sources of standing water and preventing vector mosquitoes from biting humans by using mosquito repellents and barrier methods.

[Familial Mediterranean fever in Mexico City. A 20-year follow-up]. / Fiebre mediterránea familiar en la Ciudad de México. Seguimiento durante 20 años.

Familial Mediterranean fever (MFF) is an autosomic recessive, inherited inflammatory disease principally seen in persons from the Mediterranean area. Clinical findings include fever, abdominal pain, and pleuritis. The most severe complication of MFF is renal amyloidosis, manifested as nephrotic syndrome, which evolves into chronic renal failure. In this study, we described clinical findings, evolution, and response to treatment in 52 patients diagnosed with MFF living in Mexico City in whom the most important clinical features were fever and abdominal pain. Differing from previous reported series of patients from the Mediterranean area, patient developed renal amyloidosis during the 20-year follow-up, which suggests that an environmental factor might have a significant influence in development of renal amyloidosis.

Administración crónica de los inhibidores de la bomba de protones: un problema de salud pública / Chronic administration of proton pump inhibitors: A problem of public health

Resumen En la actualidad se ha generalizado la administración de los inhibidores de la bomba de protones casi de manera universal, pero con especial insistencia en los pacientes hospitalizados. Su administración se ha considerado inocua y con efectos protectores; sin embargo, la administración indiscriminada de este grupo de fármacos tiene serias consecuencias para la salud.

Abstract Currently the use of proton pump inhibitors has become widespread almost universally but with special emphasis on hospitalized patients. Its use has been considered innocuous and with protective effects; however, the indiscriminate administration of this group of drugs has health consequences.
