Ante un paciente con fenómeno de Raynaud, compromiso visceral y ANA elevado, se deben solicitar anticuerpos específicos para el diagnóstico de esclerosis sistémica en su variedad sinusal .

(Uveitis - glaucoma - hyphema syndrome: Clinical case)

2023-05-12T03:18:53+00:00

Introduction: Uveitis-glaucoma-hyphema syndrome (UGH) is a rare complication of cataract surgery, due to mechanical chafing exerted by an intraocular lens (IOL) on the iris. Clinical case: We present the case of a 64-year-old man with a history of cataract surgery, who presented decreased visual acuity and pain in the right eye. The ophthalmological examination revealed signs of anterior uveitis, elevated intraocular pressure (IOP), microhyphema, and a single-piece foldable IOL in the sulcus that caused a mechanical chafing with the posterior face of the iris. The medical treatment was insufficient, for this reason a folding simple-piece IOL explant surgery was performed and replaced by a three-piece IOL. Postoperative evolution was favorable. Conclusion: We should suspect this complication in patients with a history of cataract surgery, especially in cases in which the IOL is in single-piece and has been implanted outside the capsular bag.

Spontaneous pneumothorax and bullous emphysema in a young patient? About a case

2023-08-17T03:42:32+00:00

Introduction

Pneumothorax is a pathology prevalent in traumatic accidents in the thorax, but it can also be found spontaneously due to causes attributable to bullous disease, pneumonia, airway obstruction, malignancy, among others.

Case report

Young male patient who debuted with spontaneous pneumothorax who required management in the intensive care unit with subsequent appearance of bullae in diagnostic images and pathology.

Discussion

Primary spontaneous pneumothorax (PSP) in the young population is influenced by psychosocial factors such as age, gender, habits, environment, and genetic factors. In 80% of patients with PSP, the presence of bullae or apical blebs has been demonstrated, in addition from the porosity of the pleura that usually occurs in tall adolescents with athletic bodies; but it is also observed that tobacco use can increase the risk.

Conclusions

Spontaneous pneumothorax due to bullous emphysema has increased in young people due to the use of psychoactive substances, vapers, and cigarettes.

Conclusion: The deficient state of health establishments has determined the increase in cases of COVID 19, during the pandemic, because they do not have adequate environments to treat different pathologies, as well as due to inadequate zoning of respiratory and vector isolation areas. , those that must respond to the reality of this Region; This situation raises the need to formulate a regional contingency plan, the same one that guarantees priority and quality care in emergency situations, as well as life during the pandemic.

Emotional intelligence and stress coping strategies in health care workers.

2023-04-19T17:40:41+00:00

Objective: To determine the relationship between emotional intelligence and stress coping strategies in health care workers of a Third Level of Care Hospital during 2021.

Methods: An analytical cross-sectional study was carried out. Two surveys were used: the COPE test which measures how to cope with stress and the Bar-On Emotional Coefficient Inventory which measures the level of emotional intelligence. The main variable was coping with stress. The independent variable was emotional intelligence.

Results: A total of 290 health care workers were worked. Emotional intelligence was significantly positively correlated (Pearson = 0.6003) with stress coping. The stress coping strategies with the highest mean were planning, positive reinterpretation and growth, and religious coping. These strategies had a positive correlation with emotional intelligence, these correlations were 0.5271, 0.5200 and 0.2051 respectively. For the multiple regression analysis, it was observed that the average BARON test score increased by 0.261 points for each point increase in the COPE TEST (coefficient = 0.261; 95%CI: 0.215 - 0.307); adjusted for all covariates of interest.

Conclusion: There is a relationship between emotional intelligence and stress coping. A relationship was also found with stress coping strategies.

Association between hematological parameters and metabolically unhealthy phenotypes in children and adolescents.

2023-05-04T02:02:59+00:00

Objective. Metabolic syndrome has been associated with changes in the composition of circulating blood cells. Hematologic indices can be used to identify the subjects at risk of metabolically unhealthy phenotype (MUP). This study investigated whether hematological indices can serve as biomarkers to distinguish metabolically healthy phenotype (MHP) from MUP in children and adolescents.

Methods. Two hundred ninety-two children and adolescents were enrolled in a cross-sectional study. The MUP was diagnosed using consensus-based criteria proposed by Damanhoury et al. Group comparisons were performed using one-way ANOVA. To examine if sex, age group, nutritional status, puberty, hematological parameters, and insulin resistance were associated with MUP, we used multiadjusted logistic regression analysis with metabolic status as the dependent variable.

Results. The subject's age mean was 11 years (SD: 2.61). RDW values were significantly lower in children with metabolically unhealthy normal weight (MUNW) compared to children with metabolically unhealthy obesity (MUO) (12.33 ± 0.90 vs. 13.67 ± 0.52; p = 0.01), and in metabolically healthy obesity (MHO) compared to MUO (13.15 ± 0.53 vs. 13.67 ± 0.52; p = 0.04). In adolescents, the PLR was higher for the MHNW group, with a mean value of 152.60 (SD 62.97) compared to 111.16 (SD 44.12) for the MHO group. After adjusting for age, nutritional status, and puberty, hematological indices were not associated with MUP.

Conclusions. The study demonstrates that hematological indices are not independently associated with the metabolically unhealthy phenotype. Hematologic indices are unlikely to represent reliable biomarkers of MU phenotype in the pediatric population.

Results: We included 116 patients, 57.7% men, mean age 47.32 years (min. 20, max. 79); 77 (66.3%) patients had moderate symptoms in hospitalization. A significant p value was obtained (p <0.000) Conclusions: Significant improvement is observed in post-COVID-19 patients after receiving respiratory physical and occupational therapy.

Effect of Tropaeolum Tuberosum "Mashua" (Tropaeolaceae) on gene expression related to spermatogenesis in mouse

2023-09-11T15:49:09+00:00

Introduction: Tropaeolum tuberosum, known as "mashua" is an Andean tuber that holds both economic and nutritional value for low-income populations. It is believed that it affects male fertility because Andean men associate it with impotence and decreased fertility. Studies conducted on rats fed with "mashua" showed that there was a 45% decrease in the testosterone/dihydrotestosterone ratio. The effect of this plant on reproduction is related to its content of isothiocyanates, compounds that covalently bind to proteins, which may be directly or indirectly involved in the spermatogenic process. The purpose of this research was to evaluate the effect of the aqueous extract of "mashua" on spermatogenesis and reproductive physiology of mice. Methodology: In vivo morphofunctional parameters of mouse sperm (spermatogram) were evaluated and the expression of Cytochrome P450 17α-hydroxylase/17,20-lyase, acute steroidogenesis regulatory protein, cyclin, and protamine related to spermatogenesis was quantified.

Results: The results indicated that at 7, 14 and 21 days of dosing, the sperm count was affected, as well as their progressive motility (PM), on the other hand, a delay in their maturation was observed. Regarding gene expression, no significant differences were found between the expression of the two genes studied (Cytochrome P450 17α-hydroxylase/17,20-lyase, Cyclin), Conclusion: The effect of "mashua" does not occur at the level of gene expression involved in spermatogenesis, but at the level of its functions as a protein.

Assessment of Mycobacterium Tuberculosis drug-resistance patterns in a public hospital of Lima, Peru during 2022

2023-07-19T22:26:09+00:00

Background. Tuberculosis is a public health problem considered to be the world's leading cause of death from an infectious disease among adults. Diagnosis is often challenging and is based on clinical, epidemiological, radiological, bacteriological, histological and biochemical findings. Timely diagnosis, identification of the susceptibility profile and follow-up compliance is important to enable more effective treatment and avoid severe forms of the disease.

Aim. Describe the resistance patterns of Mycobacterium tuberculosis identified in the period of the year 2022 at Hospital María Auxiliadora.

Material and Methods. This is an observational, cross-sectional study of patients diagnosed with tuberculosis throughout the year 2022 in the Tuberculosis Center of Excellence (TB COE), division of the respiratory medicine department at the Hospital Maria Auxiliadora, Lima, Peru. Data was collected from the medical records which was then included for the statistical analysis. The clinical and demographic characteristics were described by absolute frequencies and percentages. Chi-square test and Fisher's exact test were used to evaluate the association between the sensitivity profile of tuberculosis and the independent variables. A p-value < 0.05 was considered as statistically significant.

Results. A total of 261 medical records were included in the present study. The most frequent age group was 17-59 years old, the majority were male (62.1%) and 15.7% were relapses, as established on national technical standard. Of the total, 89.7% were sensitive to first line drugs; 6.1% of the patients were multidrug-resistant (MDR), and 0.8% presented extensively drug-resistance (XDR); likewise, 0.8% and 2.7% presented resistance for rifampicin only and resistance for isoniazid only respectively. HIV infection was found at 14.2%. The most common form of tuberculosis was pulmonary (49%) followed by pleural tuberculosis (21.8%).

Conclusion. Tuberculosis is a worldwide condition whose drug-resistance patterns continue evolving. However, in our hospital, a southern Peru reference Center, most TB patients are still sensitive to first line drugs. Only a small amount of MDR and XDR patients were found. Moreover, the most common clinical presentation was pulmonary followed by pleural tuberculosis.

2023-09-11T16:05:54+00:00

Objective: Identify neonatal pathologies or conditions that influence the prolongation of hospital stay in a Neonatal Intensive Care Unit (NICU).

Materials and methods: An observational, retrospective, case-control study was carried out; in neonates hospitalized in the NICU, during the period 2015-2019, considering their perinatal and postnatal diagnoses as factors to be evaluated, as well as hospital stay. Two groups were divided: cases (prolonged stay) and controls (non-prolonged stay). The collected data were processed in the SPSS v.23 program, obtaining the OR and the Binary Logistic Regression.

Results: 361 neonates (91 cases and 270 controls) were included, finding significance in perinatal factors (p<0.05): Birth weight (1000g to <1500g, ORa 8.2: CI3.1 - 21.2) and gestational age (28 to 31 weeks , ORa 18.6: CI4.8-71.4; 32-33 weeks, ORa 8.1: CI3.5 – 18.4); and postnatal factors (p<0.05): RDS (ORa 10.3: CI 4.8-22.2), PHT (OR 32.2: CI 1.8-559.0), sepsis (ORa 7.1: CI 3.1-16.0), Neonatal malnutrition (ORa 10.2: CI 4.7 -22.1) and anemia of prematurity (aOR 8.3: CI 2.4-28.1). The following did not reach significance: asphyxia, transient tachypnea of the newborn, pneumonia, pneumothorax, bronchopulmonary dysplasia, meconium aspiration syndrome, patent ductus arteriosus, congenital heart disease, hyperbilirubinemia, hypoglycemia, necrotizing enterocolitis, and apnea of prematurity.

Conclusions: Birth weight, gestational age, RDS, PHPT, sepsis, neonatal malnutrition and anemia of prematurity are risk factors for prolonged hospital stay.

Cytogenetic findings and maternal age in patients with Down syndrome in a pediatric referral hospital from Peru

2023-01-21T19:41:45+00:00

Introduction: Down syndrome is a congenital disorder caused by a total or partial trisomy of chromosome 21 and is considered the most common genetic cause of congenital malformations and intellectual disability. The objective of this study was to describe the cytogenetic alterations of patients with Down syndrome and their relationship with maternal age.

Methods: Cross-sectional, descriptive-analytical study. 436 patients with Down syndrome admitted to the Instituto Nacional de Salud del Niño during the 2017-2019 period were included. The variables analyzed were: cytogenetic diagnosis and maternal age.

Results: It was found that 99,3% (n=433) of patients presented some type of cytogenetic alteration and three patients presented a normal karyotype. The age of the patients at the time of sampling was between 0,03 and 17 years, the male/female ratio was 1.2:1. The most frequent cytogenetic alteration was free trisomy 21 (94,7%), followed by Robertsonian translocation (n=16) and mosaicism (n=6). In the case of maternal age, a median of 37 years was found (range: 13-47).

Conclusions: Free trisomy 21 is the most common cytogenetic condition in Down syndrome; however, the Robertsonian translocation and mosaicisms were more frequent in patients whose mothers were les than 35 years old, suggesting that there are other risk factors than advanced maternal age in this group.

Keywords: Down syndrome, cytogenetic analysis, maternal age, pediatrics.

Vaginal estrogen therapy and the risk of recurrence in women with a history of breast cancer

2023-05-05T23:39:53+00:00

Breast cancer remains the most common malignant neoplasm and one of the leading causes of mortality in women, making it a significant target for global health efforts and a public health priority. Through the use of innovative therapies, survival rates have improved, leading to the emergence of associated conditions such as genitourinary menopausal syndrome. Hormonal therapy is employed for managing this condition, significantly alleviating its symptoms and, in some cases, serving as the sole solution. The most commonly utilized approach is vaginal estrogen therapy. Nevertheless, there have been reports of a potential risk of breast cancer recurrence associated with its use. In the Spanish-speaking context, there is limited evidence discussing this topic. A search was conducted across PubMed, ScienceDirect, and MEDLINE databases, using the terms "Vaginal Estrogen Therapy," "Recurrence," and "Breast Cancer." It was determined that, on a global scale, vaginal estrogen therapy is an effective and safe therapeutic option for managing genitourinary menopausal syndrome in women with a history of breast cancer. This therapy does not appear to increase the risk of recurrence, with the exception of those undergoing treatment with aromatase inhibitors. For these individuals, alternative therapies are recommended to mitigate this potential risk.

Can vitamin D be the ray of sunshine that lights up the treatment of gastric cancer?

2023-09-10T17:37:37+00:00

Mr. Editor

Gastric cancer, a malignant neoplasm that originates in the cells of the stomach lining, represents a significant burden in terms of mortality worldwide. According to data from the American Cancer Society, the estimated mortality rate is 4.9 per 100,000 people in 2021. In South America, mortality rates from gastric cancer continue to be of concern, with countries such as Chile and Peru reporting mortality rates of 18.7 and 13.6 per 100,000 persons respectively in 2021(1).

Gastric cancer being a major pathology mentioned in other previously published studies(2).

Vitamin D is a fat-soluble hormone that occurs in two main forms, D2 (ergocalciferol) and D3 (cholecalciferol). It is produced in the skin under exposure to ultraviolet light or derived from plant sterol. It is metabolized in the liver and kidney to active forms. In addition to its role in calcium homeostasis, studies suggest that vitamin D has anticancer effects by inhibiting cell proliferation and promoting apoptosis. Thus, there is increasing interest as a potential anticancer agent(3).

Studies have demonstrated the therapeutic potential of vitamin D3 in gastric cancer. An in vitro and in vivo study found that vitamin D3 suppresses the growth of gastric cancer cells by down-regulating the expression of CD44(4). In addition, another study showed that vitamin D3 affects gastric cancer progression by repressing BMP3 promoter methylation(5).

Raising vitamin D levels to 42 ng/mL is estimated to reduce disease rates and mortality in various cancers by 18% per year(6). Inactivation of Wnt/beta-catenin signaling, induction of cell apoptosis, and inhibition of cell invasion and cancer metastasis are some of the mechanisms described(6). Some studies are described in Table 1.

Although the antitumor effects of vitamin D3 have been demonstrated in preclinical studies, there is still a lack of adequately designed clinical studies evaluating the safety and efficacy of vitamin D3 in gastric cancer. In addition, further studies on the antitumor effects of vitamin D3 in gastric cancer are needed to develop more effective therapeutic strategies(4-6).
