HIV treatment cascade in regions of Peru with the highest HIV prevalence.

OBJECTIVES: To describe the HIV treatment cascade and care continuum in regions of highest HIV prevalence in Peru. METHODS: An observational longitudinal study was carried out in 14 tertiary hospitals in Peru. These are the main hospitals that administer antiretroviral treatment (ART) in the regions that represent approximately 95% of reports of HIV/AIDS cases in Peru in 2013. We included individuals older than 18 years newly diagnosed with HIV from 1 January 2011 to 31 December 2012. Medical records were reviewed until 2015. RESULTS: A total of 2119 people living with HIV (PLHIV) were identified in the selected health facilities (mean age = 35.26 years, 78% male). 97.25% [1845/1897; 95% confidence interval (CI): 96.4-97.9%] of the patients attended the consultation at least once during the follow-up, but only 64.84% (885/1365; 95% CI: 62.2-67.4%) attended within a month after the diagnosis. After starting ART, 74.63% (95% CI: 71.9-77.2%) of PLHIV remained in healthcare. Regardless of the time after diagnosis, 88.40% (1837/2078; 95% CI: 86.9-89.7%) of PLHIV started ART during the observation time. However, 78.68% (95% CI: 76.8-80.4%) did so during the first post-treatment year and only 28.88% (95% CI: 27.9-31.9%) after 1 month. After starting treatment, it was observed that 51.60% (95% CI: 49.2-54%) of PLHIV reached viral suppression during the follow-up period. CONCLUSIONS: Further analysis and improvements in the definition of indicators are required to achieve conclusive results; however, these data will give us a general understanding of the progress of Peruvian health policies in achieving the goal established by the WHO.

Cutaneous Manifestations of Zika in Peru.

This article aims to describe the cutaneous manifestations observed in the Zika epidemic in Peru during 2016 and 2017, as well as discuss the potential differential diagnoses. During the outbreak, the main reason for seeking medical advice was the development of a pruriginous maculopapular rash with a marked papular component, which started on the chest and later generalized to the rest of the body. Similar manifestations were noted in adults, children, and pregnant women. Other manifestations such as conjunctivitis, edema, or petechiae on the palate were rare. We suggest that in areas that are endemic for arboviral infections, in the differential diagnosis of a rash one must consider infections such as dengue, Zika, or chikungunya viruses. In nonendemic areas, the diagnosis is more difficult, as the rash may result from other viral infections not transmitted by arthropods and/or reactive or inflammatory diseases (urticaria, atopic dermatitis, systemic lupus erythematosus). We recommend that primary care health personnel are trained in the recognition of the mucocutaneous lesions caused by Zika virus infection, which could contribute to the identification of suspicious cases, particularly pregnant women.

Genetic identification of newborns in Peru: A pilot study. / Identificación genética de recién nacidos en Perú: Un estudio piloto.

OBJECTIVE: To determine the feasibility of genetic identification in a group of newborns from a public hospital in Lima, Peru. MATERIAL AND METHOD: Descriptive cross-sectional study, carried out by the National Registry of Identification and Civil Status of Peru, on live newborns and their mothers, from the Carlos Lanfranco La Hoz Hospital (Puente Piedra, Lima) during January. 2015. The samples were collected in FTA (Fast Technology for Analysis of nucleic acids) cards that allowed a direct analysis by PCR (Polymerase Chain Reaction) and capillary electrophoresis of 21 STR markers (Short Tandem Repeats), including the amelogenin marker for gender determination. RESULTS: 44 mothers and 45 newborns were included (there was a twin birth). The probability of maternity was higher than 99.9% in all cases. There were no difficulties in the sampling or in transporting the material. The obtained biological material was enough to collect DNA to identify the newborn. CONCLUSIONS: The genetic identification procedure was possible to perform in this hospital. Stages of the process that could be improved were identified for the eventual application of this procedure on a larger scale in Peru.

Factors associated with the discontinuation of hormonal contraceptives in women of Lima, Peru.

INTRODUCTION: Family planning is a right and a tool that offers the possibility of choosing how many children to have. Its importance lies in the possibility of avoiding an unwanted pregnancy and its consequences. Our objective was to determine the factors associated with discontinuing hormonal contraceptives in women of childbearing age who attended the La Libertad Health Center in January 2023. METHODS: The study was observational, analytical, and cross-sectional. A total of 100 women of childbearing age who were users of hormonal contraceptives were included. Descriptive statistics were performed, frequency measurements and measures of central tendency were calculated, bivariate statistics were performed and the prevalence ratio (PR) was calculated, and a robust Poisson regression model was performed to assess the associated independent factors. All calculations were made with a confidence level of 95%. RESULTS: The educational level (PR=1.74; 95% CI: 1.22-2.48, p=0.006), the distance to the health center (PR=7.32; 95% CI: 1.1-48.5, p=0.001), having presented adverse events (PR=26.38; 95% CI: 3.8-183, p=0.001), and that the health staff had not identified the need for contraception (PR=3.12; 95% CI: 0.87-11.10, p=0.01) were associated with stopping a hormonal contraceptive. After introducing the variables to the regression model, the only independently associated factor was having presented an adverse event with the use of hormonal contraceptives (adjusted prevalence ratio, APR=3.33; 95% CI: 2.1-5.2, p<0.001). CONCLUSIONS: In this population, the factors associated with the discontinuation of hormonal contraceptives were education level, distance to the health center, having presented some adverse event with its use, and that health staff had not identified the need for contraception. The only independently associated factor was having presented an adverse event.

Association between Subclinical Hypothyroidism and Glycemic Control in Older Adults in a Medical Center in Peru.

Objective: To determine whether there is an association between subclinical hypothyroidism and glycemic control in older adults who received care at the "Centro Médico Naval" from 2010 to 2015. Methods: This retrospective analytical study analyzed a secondary database of the care of elderly in the study hospital. The sample was comprised of 1,385 older adults. To detect an association between variables, the Poisson regression with robust variance was used at a significance level of 95%. The analyses were carried out with the STATA 16 program. Results: Of the elderly 45.6% were between 71 and 80 years old; 58.4% were women and 43.8% had a normal body mass index. There was evidence of inadequate glycemic control in 8.1% and subclinical hypothyroidism in 15.2% of the elderly patients. Subclinical hypothyroidism was more frequent in the inadequate glycemic control vs. adequate glycemic control populations (41.1% vs. 13.0%). In the multivariance analysis, subclinical hypothyroidism (aPR = 2.22 95% CI [1.47-3.36]) was independent factor associated with inadequate glycemic control (p < 0.001). Conclusions: A significant association was detected between subclinical hypothyroidism and inadequate glycemic control in older adults who presented at the "Centro Médico Naval" from 2010 to 2015.

Ultrastructural skin alterations of healthy subjects with anti-desmoglein 1 antibodies in endemic areas to pemphigus foliaceus: A case series.

Background: Endemic pemphigus foliaceus and endemic pemphigus vulgaris are autoimmune dermatologic disorders endemic to the Peruvian Amazon. Objective: To determine the ultrastructural skin alterations of three healthy subjects with anti DSG-1 antibodies in areas endemic to pemphigus foliaceus and pemphigus vulgaris in the Peruvian Amazon. Patients and methods: Case series carried out from data of three clinically healthy subjects positive to anti DSG-1 antibodies, from Peru. This study consists of a sub-analysis of data gathered in a previous study. Results: Ultrastructural results are presented from the skin biopsies of three clinically healthy patients positive to anti-desmoglein 1 (DSG-1) antibodies. High Resolution Optical Microscopy (HROM) showed the absence of acantholysis. Transmission Electron Microscopy (TEM) showed the widening of intercellular space between keratinocytes, the presence of vacuoles in intercellular space with granular material and cytoplasmic vacuolization, loss of desmosome structure, loss of normal distribution among tonofilaments and lateral separation among cells in the stratum basale. Conclusion: According to our results, healthy subjects that present anti-desmoglein 1 antibodies can develop ultrastructural alterations that are visible through transmission electron microscopy but not through conventional optical microscopy.

Primary muscular hydatidosis in an endemic area of Peru: report of two cases.

Primary muscular hydatidosis is an infrequent parasitic infection, caused by Echinococcus granulosus. We report 2 cases of female patients with diagnosis of primary muscular hydatidosis of the thigh. Both hail from an endemic area for hydatidosis, and had no pulmonary, hepatic, or systemic involvement. Cyst extraction was performed after the patients were given hypertonic solution, and antiparasitic treatment.

Arsenicism by Chronic Exposure to Mine Tailings in Peru: An Analysis of 17 Cases with Lesions on Skin and/or Annexes.

Objective: To characterize the epidemiology and clinical manifestations of arsenicism from chronic exposure to mine tailings in people with lesions on their skin and/or annexes in two mining districts in the highlands of Peru. Materials and Methods: In this case series study, we included 17 people that presented arsenical lesions in skin and annexes which were identified in two prior studies. We evaluated age, occupation, place of exposure, time of exposure, time of disease, manifestations on skin and annexes, location of lesions, severity, and 24-hour urine clearance of arsenic. Results: The average time of exposure was 16.5 ± 14.7 years, and the average length of disease was 9.8 ± 8.1 years. In this study, 70.6% were men, 41.2% were farmers and 17.6% were underage. The most frequent main manifestations in skin and annexes were plantar keratosis (23.5%), palmar (11.8%), palmoplantar (11.8%) and thoracic keratosis (5.9%). Other manifestations were palmoplantar keratosis with thoracic hyperpigmentation (17.6%), Mees' lines (17.6%) and hyper/hypopigmentation in thorax and back (11.8%). With relation to the severity of lesions, 35.3% were grade 1 (mild), 29.4 % were grade 0 (asymptomatic), 29.4 % were grade 2 (moderate), and 5.9% were grade 3 (severe). The median of 24-hour urine clearance of arsenic was 55 µg/L/24 hours. No cases of skin cancer were presented. Conclusion: The studied cases of arsenicism with lesions on skin and/or annexes by exposure to mine tailings present with differential characteristics in comparison to other forms of arsenicism such as less severity, lower urine clearance of arsenic, and absence of skin cancer cases.

Exposure to Atmospheric Ozone Disruption and Altitude Over 3500 m.a.s.l. are Associated with a Higher Prevalence of Photodermatoses in Pediatric Population of High-Altitude in Peru.

Objective: To determine if exposure to atmospheric ozone disruption and other factors are associated with photodermatoses in the high-altitude pediatric population in Peru. Materials and Methods: A cross-sectional study based on data obtained from studies of dermatological diseases among the population exposed to mine tailings in Peru which included children under the age of 18 in 6 population centers located over 2500 meters above sea level (m.a.s.l). We evaluated the presence of photodermatoses and possible associated factors obtaining the adjusted odds ratio (aOR) and confidence intervals (CI). Results: 594 children below the age of 18 participated in this study, 53.0% girls, the average age was 10.4 ± 4.1 years. 51.3% were exposed to a mini hole in the ozone layer, 60.1% resided at an altitude over 3500 m.a.s.l and 51.9% presented cutaneous manifestations of atopy upon physical examination. The prevalence of photodermatoses was 64.8%, of which the most frequent were actinic prurigo (49.3%), pityriasis alba (18.5%) and actinic cheilitis (4.4%). The multivariate analysis found that residing in a region exposed to the mini hole in the ozone layer (aOR = 4.23; CI 95%: 2.32-7.72) and residing at an altitude over 3500 m.a.s.l (aOR = 2.76; CI 95%: 1.57-4.86) were both independent associated factors to photodermatoses. Conclusion: A high prevalence of photodermatoses exists among the pediatric population living at high-altitude in Peru. Residing in a region exposed to a mini hole in the ozone layer and residing over 3500 m.a.s.l constituted associated factors.

Comparison of EQ-5D Values Sets Among South American Countries.

OBJECTIVE: Social health preference sets are necessary for conducting health economic evaluations. Values from other countries are often used when local sets are not available, which may alter the results. We aimed to evaluate the degree of variability of currently available country-specific value sets of the EuroQol EQ-5D instrument from South American countries (SAC). METHODS: We selected EQ-5D value sets from SAC and 2 reference countries. We obtained crosswalk value sets for the countries that use the EQ-5D-3L instrument. We compared the value sets with the Kruskal-Wallis test and then carried out pairwise comparisons with the Sign test. We also assessed correlations among the countries' value sets using the Spearman test. We calculated the absolute difference across countries for each health state, considering a difference of greater than 0.05 relevant. RESULTS: The range of value sets varied greatly. The Peruvian value set had the widest range (1 to -1.076) and the lowest values (median: 0.055; interquartile range: -0.171 to 0.275). The Ecuadorian set had the highest values (median: 0.587; interquartile range: 0.443-0.704). The Peruvian value set also had the greatest proportion of health states (43.6%) with a negative value, and the Uruguayan set had the smallest proportion (0.9%). Differences among countries were significant in all cases, with the greatest difference between Ecuador and Peru (median difference: 0.495; 95% confidence interval: 0.515-0.528). CONCLUSION: Social health preference sets varied greatly among SAC. Using non-local values could distort resource allocation decisions; hence, we recommend that countries obtain and use local value sets.

Pregnant woman from southern Peru with rabies infection who delivered a healthy baby.

Rabies in pregnancy is rare with a high mortality. We report a pregnant woman who developed urban rabies from the bite of an infected dog. An emergency Cesarean section was performed at 31 weeks of gestation, and a premature baby was delivered who survived and did not develop rabies. The mother, however, suffered a rapid clinical deterioration and was admitted to intensive care where a Milwaukee protocol was followed. The patient survived 19 months but developed severe neurological sequelae secondary to rabies encephalitis and finally died of respiratory failure.

Facial porokeratosis: A series of six patients.

Porokeratosis is a disorder of epidermal keratinization characterized by annular plaques with an atrophic centre and hyperkeratotic edges, and includes a heterogeneous group of disorders that are mostly inherited in an autosomal dominant fashion. Facial porokeratosis is rare and is not well documented. We present six cases of facial porokeratosis seen over a period of 15 years in a hospital in Lima, Peru. In most of the cases, porokeratosis was found in younger women without any significant past medical history. Oral isotretinoin showed moderate improvement in two of our patients.

Actitudes hacia la investigación en médicos residentes de un hospital pediátrico público

Introducción: La investigación es un proceso intencional de construcción de nuevos conocimientos e ideas, que impulsan la trasformación de la sociedad. Los profesionales de la salud deben desarrollar actitudes positivas hacia la investigación, toda vez que esto mejora su desempeño profesional y, por ende, la calidad de atención al paciente. Objetivo: Identificar las actitudes hacia la investigación en médicos residentes de un hospital pediátrico público. Métodos: Estudio descriptivo transversal; se incluyeron 200 médicos residentes. Se aplicó el instrumento "Escala de actitudes hacia la investigación (EACIN)", de 39 ítems. Se empleó la prueba t de Student para muestras independientes para determinar la diferencia de los puntajes de las actitudes de investigación y las variables sexo, tipo de especialidad y experiencia laboral; mientras que para la variable horas de trabajo semanal, se empleó la prueba U de Mann-Whitney. Resultados: El 58,5 % fue de sexo femenino; el 25 % (48) mostró una actitud afectiva positiva; el 98 % (196) una actitud cognitiva positiva; el 94 % (188) una actitud conductual positiva. En general, el 96 % (192) tuvo una actitud positiva y el 4 % (8) neutral. El puntaje obtenido por los médicos residentes que realizaban especialidades quirúrgicas fue mayor que el quienes realizaban especialidades clínicas (115,69 ± 6,02 vs. 113,29 ± 5,93; p= 0,012). Conclusiones: La mayor parte de los médicos residentes presentan actitudes positivas hacia la investigación, lo cual podría ser beneficioso para implementar programas de capacitación y actividades relacionadas con la investigación en el hospital.

Introduction: Research is an intentional process of constructing new knowledge and ideas, promoting the transformation of society. Health professionals must develop positive attitudes towards research since this will improve their professional performance and therefore improve the quality of patient care. Objective: Identify the attitudes towards research in resident doctors of a public pediatric hospital. Methods: The study was descriptive cross-sectional; 200 resident doctors were included. The "Research Attitudes Scale (EACIN)" of 39 items was applied. The T-Student test for independent samples was used to determine the difference in the scores of research attitudes, and the variables sex, type of specialty and work experience, while the Mann Whitney U test was used for the weekly work hours variable. Results: 58.5% were female, 25% (48) showed a positive affective attitude, 98% (196) a positive cognitive attitude, 94% (188) a positive behavioral attitude. In general, 96% (192) had a positive attitude and 4% (8) had a neutral attitude. The score obtained by resident physicians who performed surgical specialties was higher than that of those who performed clinical specialties (115.69 ± 6.02 versus 113.29 ± 5.93; p= 0.012). Conclusions: Most resident doctors have positive attitudes towards research, which could be beneficial to implement training programs and/or activities related to research in the hospital.

Antidesmoglein 1 and 3 antibodies in healthy subjects of a population in the Peruvian high amazon.

BACKGROUND: The objective of this study was to determine the presence of anti-Dsg1 and Dsg3 antibodies in healthy subjects of the high Peruvian Amazon (Tuemal, Rodriguez de Mendoza province, department of Amazonas) to establish the theoretical presence of environmental factors or triggers in the area. MATERIALS AND METHODS: Cross-sectional study. The study population included persons of any age or gender, clinically healthy, who were evaluated by a dermatologist to confirm the absence of blistering diseases. Blood samples were analyzed by indirect immunofluorescence (IIF), immunoprecipitation (IP), anti-Dsg1 IgM antibody (Ab) enzyme-linked immunosorbent assay (ELISA), as well as anti-Dsg1 and anti-Dsg3 IgG Ab ELISA. RESULTS: Participants included 21 healthy subjects comprised of 61.9% males and 38.1% females; 47.6% had a positive anti-Dsg1 Ab ELISA for total IgG (or any subclasses). IIF detected antibodies against intercellular spaces in one subject. Anti-Dsg1 Ab IP was mildly positive in 33.3% of the subjects. Anti-Dsg1 IgG subclasses found positive were: IgG1 (19.0%), IgG2 (33.3%), and IgG3 (28.6%); none of the samples were positive for anti-Dsg1 Ab IgM ELISA, and 23.8% of the subjects were positive for anti-Dsg3 Ab ELISA. The age distribution was similar for subjects positive for anti-Dsg1 and anti-Dsg3 Ab ELISA, with higher frequencies found among the 20-29 and 40-49 year-old age groups. CONCLUSION: A fraction of healthy subjects of the high Peruvian Amazon developed anti-Dsg1 and anti-Dsg3 antibodies, demonstrating the possible presence of environmental factors for endemic pemphigus (EP) at a higher altitude than previously described.

[Interventions to prevent the development of overweight and obesity in children younger than five years]. / Intervenciones para prevenir la aparición de sobrepeso y obesidad en niños menores de cinco años.

Childhood obesity is one of the most severe public health problems worldwide. The present study describes the interventions used to prevent overweight and obesity in children younger than 5 years. The objective of the interventions was to stimulate breastfeeding, monitor the child's growth, and promote adequate complementary feeding by means of nutritional counseling using a responsive feeding approach in different settings, including health centers and residences. The interventions included physical activity and nutritional counseling, with the active participation of the parents. The quality of evidence from most studies was high because the evidence was derived from controlled clinical trials, systematic reviews, and meta-analyses. All interventions were conducted or could be replicated in Peru by adequate contextualization.

La obesidad infantil representa uno de los mayores problemas de salud pública a nivel mundial. En el presente artículo se exponen las intervenciones para prevenir el sobrepeso y obesidad en niños menores de cinco años. Las intervenciones dirigidas a prevenir la obesidad en infantes fueron: promoción de la lactancia materna, vigilancia del crecimiento del niño y promoción de una adecuada alimentación complementaria, a través de la consejería nutricional con enfoque de alimentación responsiva, brindadas en distintos escenarios como el centro de salud o basados en el hogar a través de visitas domiciliarias. Las intervenciones dirigidas a prevenir obesidad en los preescolares incluyen las intervenciones con componentes de actividad física y nutrición que involucren activamente a los padres. La calidad de la evidencia de la mayoría de estudios es alta debido a que proviene de ensayos clínicos controlados, revisiones sistemáticas y metaanálisis. Todas estas intervenciones se realizan o podrían ser replicadas en nuestro país, mediante una adecuada contextualización.

ABSTRACT: OBJECTIVES : To determine the clinical and epidemiological characteristics in older adults with hip fracture in a hospital in Lima, Peru. METHODS : Case series type study carried out in the trauma department of the PNP Central Hospital "Luis N. Saenz" during the period 2015-2018. Medical records of patients diagnosed with hip fracture were reviewed. RESULTS : A total of 140 medical records were included. A predominance was found in the female sex (54.3%) and in patients over 80 years old (45%). Most of these events occurred at home (81.4%). Intertrochanteric fractures were the most frequent (60%), especially on the right side (51.4%), osteosynthesis was the most used therapeutic option (62.1%). Pain (92%) and functional impotence (91.4%) were the characteristic clinical presentation of hip fractures, and arterial hypertension was the most common associated pathology (52.2%). CONCLUSIONS : Hip fracture primarily affects people over 80 years of age, especially women with high comorbidity. The highest percentage occurs as a result of falls produced at home, with pain on the affected side being the main manifestation. The most common type of fracture is intertrochanteric, and the most used treatment is osteosynthesis.

[El niño phenomenon and natural disasters: public health interventions for disaster preparedness and response]. / Fenómeno el niño y desastres naturales: intervenciones en salud pública para la preparación y respuesta.

This article reviews public health interventions for preparedness and response to natural disasters within the context of El Niño phenomenon using systematic reviews and a review of revisions with emphasis on vector-borne diseases, water-borne diseases, malnutrition, heat stress, drought, flood-associated diseases, mental health problems, vulnerability of the physical health-system infrastructure, as well as long-term policies aimed at protecting the populations of these cases. Environmental interventions were identified, including vector control, chemoprophylaxis, immunization, and intradomiciliary water treatment. While these finds are based primarily on systematic reviews, it is necessary to evaluate the benefit of these interventions within the population, according to the context of each region.
