The western blot test was standardized, using the polyacrylamide gel electrophoresis technique with sodium dodecyl sulfate (SDS PAGE), being the nitrocellulose blot strips prepared with an Optimal HIV-1 antigen concentration of 2.71 µg / mm. The western blot was validated in the laboratory against 400 reference samples (300 sera and 100 plasmas): 200 positive and 200 negatives for antibodies against HIV-1, being the reference test the Immunoblot of the Fujirebio brand. Diagnostic performance parameters were estimated using Epidat v3.1 and Excel.&nbsp;<strong>Results:</strong>&nbsp;Eight important bands of the HIV-1 antigen were identified: p17, p24, p31, p39, gp41, p55, p66, and gp120. According to the Consortium for the normalization of serology for retroviruse, those that were taken as specific diagnostic bands were: p24, p31, gp41, and gp120. The sensitivity, specificity, positive and negative predictive value and validity index against sera were: 96.7%, 96.0%, 96.0%, 96.6%, 96.3%; and against plasmas: 98.0%, 100.0%, 100.0%, 98.0%, 99.0% respectively. No false positives and negatives were found, but some were undetermined.&nbsp;<strong>Conclusion:</strong>&nbsp;The development of this western blot test with proprietary technology presented similar diagnostic performance to the reference test, without showing cross-reactions, being useful for confirming HIV.</p> Eduardo Fernando Miranda Ulloa Soledad Romero Ruiz Bernardina Amorín Uscata Kevin Serrano Segura Ronal Briceño Espinoza Fany Cárdenas Bustamante ##submission.copyrightStatement## 2021-08-20 2021-08-20 21 4 10.25176/RFMH.v21i4.4023 Echocardiographic parameters related to pulmonary arterial hypertension in patients with chronic myeloid leukemia under dasatinib treatment <p><strong>Introduction:</strong>&nbsp;The use of dasatinib in patients with CML has improved life expectancy and follow-up with transthoracic echocardiography (ECOTT) for early detection of PAH allows modifications to the treatment.&nbsp;<strong>Objective:</strong>&nbsp;To determine the echocardiographic parameters and echocardiographic probability for PAH in patients with CML treated with dasatinib.&nbsp;<strong>Methods:</strong>&nbsp;Correlation, cross-sectional, retrospective, single-center study; patients with CML treated with dasatinib were included. Spearman and Pearson correlation was used.&nbsp;<strong>Results:</strong>&nbsp;16 patients were analyzed, mean age 53.5 years; 62.5% men, 37.5% women. The dasatinib dose was 50 mg / day in 18.7%, and 100 mg / day in 81.2%, mean pulmonary arterial pressure (mPAP) 26.3 mmHg, mean maximum tricuspid regurgitation velocity (VmxRT) 2.9 m / s, mean pulmonary artery systolic pressure (PSAP) 41 mmHg. 56.2% had right ventricular diastolic dysfunction (RVDD). 43% were categorized as low probability for PAH, 18.7% intermediate, and 37.5% as high. Relationship between PAPm and VmxRT with p = 0.012. Relationship between mPAP and RV diastolic function, with p = 0.002. Relationship between probability for PAH and mPAP, with p = 0.008.&nbsp;<strong>Conclusion:</strong>&nbsp;The echocardiographic parameters PAPm, VmxRT, PSAP, DDVD and echocardiographic probability for PAH are useful and necessary for the diagnosis of PAH. The determination of all these parameters should be carried out early and as a follow-up, since a considerable positive relationship was found for each one with the presence of PAH, which is not dependent on the treatment time or the dose of dasatinib.</p> Karla Poot Noh Ernesto Hernández Jiménez María del Rayo Juárez Santiesteban Patricia Zaqoya Martínez Alvaro José Monliel Jarquin Arturo García Galicia David Eduardo Herrera Solano ##submission.copyrightStatement## 2021-09-07 2021-09-07 21 4 10.25176/RFMH.v21i4.4265 Clinical epidemiological characteristics of patients diagnosed with SARS-CoV-2.

From January to December 2016, non-oncological CYSHCN hospitalizations were registered by the Pediatric Service (PS) according to the Ministry of Health-Chile (MINSAL) norm. It was classified for clinical groups and similar consumption of resources according to groups related to diagnosis (DRG). The stay was adjusted, and financial analysis of both modalities (CC) and (HH) was performed to evaluate the impact on hospital production.&nbsp;<strong>Results:</strong>&nbsp;Of 3690 discharges, 126 (3.4%) were related to 27 CYSHCN, the average age was 4.6 years (± 5 SD) with technological dependencies to live. The mean CYSHCN stay was 16 days, compared with 5.9 for patients without special health needs. CYSHCN stays reached 2017 days (8.6%). Disregarding the CYSHCN discharges would have contributed 320 additional discharges, and his HH would have saved US $ 15 / day per patient, which for the total number of stays consumed would have been an annual saving of US $ 29170.&nbsp;<strong>Conclusion:</strong>&nbsp;HH has an estimated cost lower than the CA of high complexity CYSHCN, improves hospital productivity, and frees critical beds with financially viable investment.</p> Francisco Prado Atlagic Carlos Valdebenito Parra Niscka Babaic Müller Pamela Salinas Flores Fernando Muñoz Berríos Marie Jáuregui Abraham Nelson A.

It has been found that opposition to this request is often associated with homophobia. In Peru, no studies exist on these aspects.&nbsp;<strong>Objective:</strong>&nbsp;To determine the correlation between adoption approval and attitude towards homosexuality in medical students and graduates, Lima, Peru. Method: The observational and cross-sectional study was carried out. 205 people over 21 years of age participated. The Attitude Toward Homosexuality Scale (EAH-10) and the question “Should homosexual couples be allowed to adopt children like heterosexual couples?” were used. The relationships were made with the Pearson (r) and Spearman (rs) correlation coefficient.&nbsp;<strong>Results:</strong>&nbsp;Quantitatively, a negative and significant correlation was found between the response with the attitude towards homosexuality (r = -0,727; rs = -0,718) and a positive and significant correlation with the number of homosexual friends (r = 0,402; rs = 0,399). 57,6% indicated approval of the question posed. Greater intolerance attitudes were found in men than in women (r = 0,328; p = 0,000). A multiple linear regression model showed that attitude towards homosexuality, sex, and number of homosexual friends are good predictors of acceptance of homosexual adoption.&nbsp;<strong>Conclusion:</strong>&nbsp;The response was significantly correlated with attitudes of homophobia and with the number of homosexual friends. Furthermore, homophobic attitudes were higher in men.</p> Marco Antonio Tipula Lincol Marx Cruz Aquino María Isabel Vásquez Suyo Maritza Dorila Placencia Medina ##submission.copyrightStatement## 2021-09-08 2021-09-08 21 4 10.25176/RFMH.v21i4.3817 Correlation between mortality due to COVID-19, wealth index, human development and population density in districts of Metropolitan Lima during 2020 <p><strong>OBJECTIVE:</strong>&nbsp;To determine the correlation between mortality due to COVID-19 and incidence of poverty and district human development index (HDI) in the department of Lima.&nbsp;<strong>METHODOLOGY:</strong>&nbsp;An observational, ecological, correlational study. The population were patients who died from COVID-19 in Lima Metropolitana. We included all patients reported dead in the open data base of the Ministerio de Salud. The dependent variable was mortality due to COVID-19, calculated by dividing the number of deaths by the total district population, and the independent variables were the incidence of poverty and HDI. We carried out a secondary analysis evaluating the fatality by COVID-19. The correlation was calculated through Spearman’s non-parametric method.&nbsp;<strong>RESULTS:</strong>&nbsp;13 154 people died of COVID-19 during the period between March and September, the majority was of masculine gender with an average age of 66 years. We did not find a significant correlation between mortality and incidence of poverty (rho=-0,2230; p=0,15). We found a significant correlation between mortality due to COVID-19 and HDI (rho= 0,4466; p=0,002). Mortality was correlated with population density (rho=0,7616; p=&lt;0,001). We found a positive (rho=0,32) and significant (p=0,037) correlation between fatality and incidence of poverty. We found a significant correlation between fatality due to COVID-19 and population density (rho=0,7616; p=&lt;0,001). We did not find a significant correlation between fatality and HDI.&nbsp;<strong>CONCLUSIONS:</strong>&nbsp;Population density was a factor associated in the most consistent manner with mortality and fatality due to COVID.

The analysis was carried out by province, sex, age, suicide method and frequency in days after the event occurred. The suicide mortality rate (per 100,000 inhabitants) was estimated for each province. <em>Results:</em> During the confinement due to a state of exception in 2020 in Ecuador, 97 suicides were registered in adolescents between 10 and 19 years of age. The highest number was estimated in males between 15 and 19 years of age, with the most frequent age being 19. The most frequent day of removal of corpses was on Mondays, and the preferred mode of suicide was hanging with 81 reported cases. followed by far by intoxication and poisoning.<em> Conclusions:</em> Adolescent suicide deserves special attention in our environment, as it is a public health problem, influenced by various psychological and emotional factors, which can be exacerbated or neglected in a context of pandemic and isolation. Significant differences are observed in variables such as sex, age group, and geographic region.

The study population was made up of patients treated in the Endocrinology Units of the Antonio Lorena and Regional Hospitals of Cusco, diagnosed with type 2 diabetes and of Quechua origin evidenced by their mother tongue. The sample is non-probabilistic for convenience, the representativeness of the discourse was sought for this, reaching 30 interviews based on the saturation criterion. The information analysis included 1. The transcription (from oral Quechua to written Quechua) and the translation of the interviews and 2. The computerized processing of the interviews, for which purpose the RQDA (Research qualitative data analysis) computer program was used.&nbsp;<strong>Results:</strong>&nbsp;The ideas that patients have about the cause of their disease and the changes that it produces reflect the influence of Modern Medicine and Andean and Popular Medicine. On the other hand, for the treatment of their disease, they consider it useful to combine the medications that have been indicated in the health service with the resources of Andean and Popular Medicine (medicinal herbs and other natural products).&nbsp;<strong>Conclusion:</strong>&nbsp;The patients in our study have an intercultural approach to approach and treat.</span></p> Ramón Figueroa Mujica Guisela Yábar Torres ##submission.copyrightStatement## 2021-09-21 2021-09-21 21 4 10.25176/RFMH.v21i4.4232 Hantavirus in the peruvian jungle: a systematic review of series and cases reported <p>Hantavirosis is a zoonotic infection transmitted mainly by rodents.

This entity has a frequency of 10 to 15% in women of reproductive age, and its most common site of presentation is the ovary. At the extrapelvic level, the most common location is the gastrointestinal and genitourinary location. However, it can occur in any location.&nbsp;<strong>Presentation:</strong>&nbsp;The case of a 40-year-old female patient with a face tumor in the mandibular region is described, presenting with a disease time of 2 years. Among the important antecedents, two months before the appearance of the tumor region, the patient underwent endodontic surgery of a lower molar tooth, contiguous to the mandibular. Likewise, one month before the appearance of the tumor, the patient underwent an exploratory laparoscopy for electrofulguration of endometriotic foci in the uterine myometrium. The patient underwent a surgical resection of the tumor in the mandibular region described; and after reviewing the histological and immunohistochemical slides at the institution, the diagnosis of endometriosis was established.&nbsp;<strong>Conclusion:</strong>&nbsp;Extrapelvic endometriosis is rare in our country, and its diagnosis requires experience and visual training in the recognition of normal endometrial tissue. The presentation of this case was considered important because it would be the first case reported in Peru and in the world, of an endometriosis located in the mandibular region.</p> Katherine Luisa Contreras Gala Mónica Villafuerte Rozas ##submission.copyrightStatement## 2021-09-13 2021-09-13 21 4 10.25176/RFMH.v21i4.4033 Posner – Schlossman Syndrome: case report <p><strong>Introduction:</strong>&nbsp;Posner - Schlossman Syndrome (PSS) is a rare disease, more prevalent in men between 20 and 50 years old, characterized by recurrent attacks of anterior uveitis and ocular hypertension.&nbsp;<strong>Clinical case:</strong>&nbsp;We report the case of a 42-year-old patient with a single eye.

The ophthalmological examination revealed inflammatory signs in the anterior segment, elevated intraocular pressure and damage to the optic nerve. Medical treatment was started with corticosteroids and topical antiglaucoma drugs, oral acetazolamide and intravenous mannitol, obtaining no response and it was decided to perform a surgical intervention (Ahmed valve implantation) in the left eye, subsequently achieving a good clinical evolution and resolution of the case.&nbsp;<strong>Conclusion:</strong>&nbsp;This report highlights that the episodic and recurrent nature of SPS requires strict monitoring.</p> Diego José Mamani Maquera Nahuel Pantoja Dávalos ##submission.copyrightStatement## 2021-08-20 2021-08-20 21 4 10.25176/RFMH.v21i4.3902 Clinical performance of a new prediction rule of systemic loxoscellism. case report <p>Systemic or cutaneous-visceral loxoscelism is the most severe clinical presentation of loxoscelism. Currently there is no validated laboratory diagnostic method that allows us to confirm the presence of this disease in the face of arachneism.

From that time until the end of the 20th century, in scientific literature, approximately 100 cases were reported that presented symptoms of depression, anxiety, nihilist delusions concerning the body and existence, hypochondriacal and immortality delusions, as well as auditory and visual hallucinations. We present the case of a female patient, 73-years old, from Ayacucho, with a history of sexual assault at the age of 12 and suicidal attempts on 2 occasions, diagnosed with depression at 40 years of age, received treatment with quetiapine, trazadone and clonazepam. She remained with fluctuating medical progress, with symptoms worsening with stressors such as the death of her mother and husband and when she underwent surgeries. Currently, she presents sad and anxious mood, daily crying, ideas of guilt, disability and death, insomnia of conciliation, nihilistic delusive ideas concerning the body, referring that her stomach and bladder do not work, reason why she doesn’t want to eat or drink water. Due to the total refusal of food intake and persistent suicidal ideation, she was hospitalized to receive psychiatric treatment and nutritional support. It is concluded that there are few cases reported on the use of psychotherapy in Cotard's syndrome. Therefore, this case in which psychotherapy was indicated to reduce anxious-affective symptoms, to avoid isolation of the person and to redirect his personal and social life, is important.</p> Héctor Ocampo Ramos Richard Jeremy Febres Ramos Sheron Arestegui Saavedra Rosa Bravo Torres Danitza Cardenas Peralta ##submission.copyrightStatement## 2021-08-20 2021-08-20 21 4 10.25176/RFMH.v21i4.3303 Parapharyngeal Schawannnoma. Case Report <p>Parapharyngeal tumor lesions present a low incidence, representing between 0,5 and 0,8% of all head and neck tumors. Approximately 80% show benign behavior. The uniqueness of these lesions derives from their complex anatomical situation and the symptoms with which they usually appear, being in most cases nonspecific and almost always derived from the compressive effect produced by the lesion on the oropharynx and the oropharynx. Schwannomas of the parapharyngeal space are very rare tumors that originate from the sheath of schawnn, generally slow growing, and are usually asymptomatic.
