Children and adolescents with sickle cell disease: characteristics and use of medicinal plants / Crianças e adolescentes com doença falciforme: características e uso de plantas medicinais

ABSTRACT Objective: The aim of this study was to describe the epidemiological characteristics of pediatric patients with sickle cell disease (SCD) and evaluate the use of medicinal plants in these patients concomitantly with their drug treatment. Methods: This is a review of the medical records of pediatric patients at a public institution with tertiary care. The selection criterion was to be a child or adolescent with SCD undergoing pediatric follow-up at this outpatient clinic. In the medical records of the patients selected, records of the use of plants for medicinal purposes were sought. Results: In total, 154 records (100% of total active patients followed in this clinic) were reviewed: 99 children and 55 adolescents. The predominant genotype was SS (58.4%), followed by SC (29.2%). The use of at least one medication for SCD was reported in 95.5% of the medical records. The use of medicinal plants was reported by 70.1% of patients, with 276 citations in the medical records referring to 64 different types of plants. Six plants were used for the treatment of SCD, the main one being Lemonvine/Ora-pro-nóbis (Pereskia aculeata). The use of medicinal plants was reported for flu-like symptoms and/or COVID-19 (both for prevention and treatment) by 60.5% of the citations, with 35 different plants reported for this use, exclusively or not. This use was followed by pain symptoms (14.2% of citations). Conclusions: The majority of patients in this study use both conventional and traditional/complementary/alternative medicine, highlighting the need for more studies in the area, with a special focus on patient safety.

RESUMO Objetivo: Descrever as características epidemiológicas de pacientes pediátricos com doença falciforme (DF) e avaliar o uso de plantas medicinais concomitantemente ao tratamento medicamentoso. Métodos: Realizou-se revisão de prontuários de pacientes pediátricos de uma instituição pública com nível de atendimento terciário; o critério de seleção foi ser criança ou adolescente com DF em acompanhamento pediátrico neste ambulatório. Nos prontuários dos pacientes selecionados foi procurado o registro do uso de plantas com finalidades medicinais. Resultados: Foram revisados 154 prontuários (100% dos pacientes ativos desse ambulatório): 99 crianças e 55 adolescentes. O genótipo predominante foi SS (58,4%), seguido do SC (29,2%). O uso de ao menos uma medicação para a DF foi relatada em 95,5% dos prontuários. Em 70,1% dos prontuários havia o relato do uso de plantas medicinais, em 276 citações, sendo 64 plantas citadas ao todo; destas, seis espécies foram citadas para o tratamento da doença de base (DF), sendo "ora-pro-nobis" (Pereskia aculeata) a principal. Das 276 citações de plantas medicinais nos prontuários, 60,5% incluíram o uso de plantas medicinais em sintomas gripais e/ou COVID-19 (tanto prevenção quanto tratamento), sendo relatadas 35 para este uso, exclusivamente ou não. Essa foi a principal finalidade de uso encontrada nos prontuários dos pacientes, seguida do uso para sintomas de dor (14,2% das citações). Conclusões: Notou-se que a maioria dos pacientes avaliados faz uso da medicina convencional, aliada à tradicional/ complementar/ alternativa, o que leva à necessidade de mais estudos nessas áreas, especialmente na pediatria, visando principalmente à segurança do paciente.

Guardians of the ocular surface: lessons learned from a challenging case of Langerhans cell histiocytosis with eyelid involvement

ABSTRACT Langerhans cell histiocytosis comprises a heterogeneous range of clinical manifestations secondary to clonal proliferation of histiocytes, characterized by the accumulation of these cells in various organs and tissues. The ophthalmological component commonly involved is the orbit. Herein, we report a rare case of Langerhans cell histiocytosis with eyelid involvement, which resulted in severe ocular surface complications, which subsequently significantly impacted the patient's quality of life. This case report highlights the fact that despite being rare, Langerhans cell histiocytosis should be included in the differential diagnosis of eyelid lesions. Furthermore, a multidisciplinary approach with a systemic overview is crucial for managing the ocular complications.

Rare case of mantle cell lymphoma of the lacrimal sac

ABSTRACT Mantle cell lymphoma of the ocular and periorbital regions is extremely rare but should be considered in the differential diagnosis of lesions affecting the periorbital tissues. In this study, we present a rare case of mantle cell lymphoma of the lacrimal sac in a 65-year-old male presenting with a mass in the lacrimal sac region and epiphora. After clinical examinations and imaging studies, the mucocele was misdiagnosed. Considering the unexpected findings during external dacryocystorhinostomy, a frozen biopsy was performed, which confirmed the diagnosis of lymphoma.

Anterior lamellar corneoscleral keratoplasty for the management of corneal thinning following treatment with mitomycin-C and interferon to treat highly suspected ocular surface squamous neoplasia: a case report

ABSTRACT A patient presented with corneoscleral thinning five months after the treatment of suspected ocular squamous surface neoplasia with mitomycin-C and interferon. For tectonic and aesthetic purposes, we decided to perform lamellar corneoscleral transplantation. The approach used established new tectonic support and corneal homeostasis. This technique might be an option in similar cases.

Prevalencia y caracterización de la anemia en cirugía electiva en un Hospital Universitario

está disponible en el texto completo

Introduction: Anemia is a highly prevalent disorder. Preoperative anemia is associated with higher mortality, more complications, longer hospital stays, and higher healthcare costs. Red blood cell transfusion (RBC) does not improve these outcomes. The World Health Organization recommends implementing Patient Blood Management (PBM) programmes, as they can improve these clinical outcomes, reduce unnecessary RBC transfusions, and save costs. Despite compelling evidence, the implementation of these measures has yet to be effectively achieved. The objective of this study is to conduct a situational analysis to raise awareness about this issue and encourage the implementation of these measures. Methodology: An observational, longitudinal, retrospective cohort study was conducted at a single center. All patients undergoing elective surgery from 01/01/2022 to 01/04/2022 at the Hospital de Clínicas were included. Exclusion criteria: absence of a complete blood count in the three months prior to surgery and refusal to participate in the study. Results: A total of 329 surgeries were analyzed. 52 out of 100 procedures were performed on patients with anemia. A statistically significant association was found between preoperative anemia and receiving RBC transfusion during hospitalization. OR 11.746 (4.518 - 30.540). Anemia and RBC transfusions significantly prolonged hospital stay. Length of hospitalization based on patient condition: No anemia: 10.1 ± 1.1 days, with anemia: 27.2 ± 2.3 days. Value of p < 0.001. Non-transfused: 14.5 ± 1.3 days, transfused: 41.8 ± 4.4 days. Value of p < 0.001. Only 49 (28.6%) of the 171 patients with anemia had iron metabolism assessed before surgery. Among the 140 patients with Hb < 12 g/dL undergoing surgeries with non-insignificant bleeding, only 4 received specific treatment to optimize Hb. A total of 185 units of red blood cells (RBC) were administered during hospitalization. 49 to unstable patients (intraoperative or acute hemorrhage) and 136 to stable patients. From the analysis of the latter group, 42.5% of the patients received 3 or more RBC units. The average pre-transfusion hemoglobin was 7.0 ± 0.1. A statistically significant association was found between receiving RBC units and dying during hospitalization. OR 17.182 (3.360 - 87.872). Conclusiones: A situational analysis was conducted, revealing a high prevalence of preoperative anemia, scarce study and treatment of anemia before surgeries, and an excessive amount of blood transfusions received by some patients. This work establishes the need to implement Patient Blood Management programs to reduce the prevalence of preoperative anemia and improve our transfusion practices. It also sets a comparative framework to evaluate the progress of these measures and indicates possible indicators to assess the benefits of their implementation.

Introdução : A anemia é um distúrbio altamente prevalente. A anemia pré-operatória está associada a maior mortalidade, mais complicações, tempo prolongado de internação e maiores custos de saúde. A transfusão de glóbulos vermelhos (TGV) não melhora esses resultados. A Organização Mundial da Saúde recomenda a implementação de medidas de Gerenciamento de Sangue do Paciente (GSP), pois permitem melhorar esses resultados clínicos, reduzir TGV desnecessárias e economizar custos. Apesar da evidência contundente, a implementação dessas medidas ainda está aquém de ser efetivada. O objetivo deste trabalho é realizar uma análise da situação para conscientizar sobre o problema e incentivar a implementação dessas medidas. Metodologia: Foi realizado um estudo observacional, longitudinal, retrospectivo de coorte histórica, unicêntrico. Foram incluídos todos os pacientes submetidos a cirurgias de coordenação de 01/01/2022 a 01/04/2022 no Hospital de Clínicas. Critérios de exclusão: ausência de hemograma nos três meses anteriores à cirurgia e recusa em participar do estudo. Resultados: Foram analisadas um total de 329 cirurgias. 52 a cada 100 procedimentos foram realizados em pacientes com anemia. Foi encontrada uma associação estatisticamente significativa entre a anemia pré-operatória e a recepção de TGR durante a internação. OR 11,746 (4,518 - 30,540). A anemia e as TGR prolongaram significativamente a internação hospitalar. Dias de internação em função da condição do paciente: Sem anemia: 10,1 ± 1,1 dias, com anemia: 27,2 ± 2,3 dias. Valor p < 0,001. Não transfundidos: 14,5 ± 1,3 dias, transfundidos: 41,8 ± 4,4 dias. Valor p < 0,001. Apenas 49 (28,6%) dos 171 pacientes com anemia tinham metabolismo do ferro antes da cirurgia. Dos 140 pacientes com Hb < 12 mg/dL submetidos a cirurgias com sangramento não insignificante, 4 receberam tratamento específico para otimizar a Hb. Foram administradas um total de 185 unidades de glóbulos vermelhos (UGV) durante a internação. 49 em pacientes instáveis (intraoperatório ou hemorragia aguda) e 136 em pacientes estáveis. Da análise desses últimos, 42,5% dos pacientes receberam 3 ou mais UGV. A hemoglobina pré-transfusional média foi de 7,0 ± 0,1. Foi encontrada uma associação estatisticamente significativa entre receber UGV e falecer durante a internação. OR 17,182 (3,360 - 87,872). Conclusões: Foi realizado uma análise da situação na qual foi observada uma elevada prevalência de anemia pré-operatória, um estudo e tratamento escasso da anemia antes das cirurgias e uma quantidade excessiva de UGV recebidas por alguns pacientes. Este trabalho estabelece a necessidade de implementar programas de Gerenciamento de Sangue do Paciente para reduzir a prevalência de anemia pré-operatória e melhorar nossas práticas transfusionais. Além disso, estabelece um quadro comparativo para avaliar o progresso dessas medidas e aponta possíveis indicadores para avaliar os benefícios de sua implementação.

Presence of Merkel cell polyomavirus DNA and large-T antigen in keratinocyte carcinomas and its correlation with immunohistochemical markers p16, p53 and ki67

Abstract Background Merkel cell polyomavirus (MCPyV), a human polyomavirus that is unequivocally linked to merkel cell carcinoma (MCC), has been found in association with keratinocytes carcinomas (KC), especially basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC). Nevertheless, there is scarce information about the possible involvement of MCPyV in the development of KC. Objectives To assess the presence of MCPyV DNA and Large-T Antigen (LT-Ag) via Polymerase Chain Reaction (PCR) and Immunohistochemistry (IHC) in cases of KC, and to correlate its presence with immunohistochemical markers p16, p53, and ki67, tumor type and subtype, sun-exposed location, and epidemiological data. Methods The prevalence of MCPyV DNA, LT-Ag, and immunohistochemical markers p16, p53, and ki67 was assessed by PCR and Immunohistochemistry (IHC) in 127 cases of KC, these results were correlated with tumor type and subtype, sun-exposed location, and epidemiological data. Results The MCPyV DNA was detected in 42.57% (43 of 101) cases by PCR, the LT-Ag was detected in 16.4% (20 of 122) of cases, p16 in 81.5% (97 of 119), p53 in 66.4% (83 of 125), ki67 in 89% (73 of 82). No correlation between MCPyV LT-Ag and DNA confronted with tumor type, subtype, location site, and immunohistochemical markers was found. A single correlation between the MCPyV LT-Ag and cSCC tumors and peri-tumoral lymphocyte cells was noted. Study limitations Further steps need to be taken to better evaluate the MCPyV influence and its possible role in KC carcinogenesis, as the evaluation of the virus genome state, the gene sequence that encodes LT-Ag in the KC tumor cells, and in situ hybridization for viral DNA or RNA in these cells. Conclusions Despite the frequent detection of MCPyV in KC, the data available so far does not support the hypothesis of a causal relationship between them.

Carcinoma escamoso variedad sarcomatoide de lengua. Reporte de caso / Sarcomatoid variant squamous cell carcinoma of the tongue. Case report

Introducción. El carcinoma de células escamosas es una patología relativamente frecuente en Paraguay, que debe ser diagnosticada y tratada a tiempo. La variedad sarcomatoide es un subtipo poco frecuente, pero mucho más agresivo que la presentación convencional, con altas tasas de recurrencia y metástasis linfática. La exposición previa a radiación es uno de los principales factores desencadenantes. Caso clínico. Paciente de 83 años con antecedente de radioterapia por carcinoma escamocelular del paladar blando, quien consultó por una masa en el borde lateral de la lengua que correspondió a un carcinoma escamocelular del subtipo sarcomatoide. Resultados. El paciente fue sometido a cirugía y quimioterapia, pero presentó recaída tumoral a los cuatro meses, sin aceptar una cirugía de rescate, optando por el tratamiento paliativo y falleciendo a los pocos meses. Conclusión. El examen exhaustivo de la cavidad oral en una primera consulta permite identificar lesiones en estadios tempranos y el tratamiento multidisciplinario temprano puede mejorar la supervivencia global. El pronóstico de estos pacientes en estadios avanzados es desalentador. Actualmente la cirugía microvascular es la mejor opción terapéutica, pero la hemiglosectomía sin reconstrucción sigue siendo una opción aceptable en nuestro medio, conociendo los altos costos de la primera y el requerimiento de un grupo mayor de especialistas, largos tiempos quirúrgicos y estancias hospitalarias.

Introduction. Squamous cell carcinoma is a relatively common pathology in Paraguay, which must be diagnosed and treated on time. The sarcomatoid variety is a rare subtype, but much more aggressive than the conventional presentation, with high rates of recurrence and lymphatic metastasis. Previous exposure to radiation is one of the main triggering factors. Clinical case. An 83-year-old patient with a history of radiotherapy for squamous cell carcinoma of the soft palate, who consulted for a mass on the lateral edge of the tongue that corresponded to a squamous cell carcinoma of the sarcomatoid subtype. Results. The patient underwent surgery and chemotherapy, but had tumor relapse after four months, without accepting salvage surgery, opting for palliative treatment and dying a few months later. Conclusion. Exhaustive examination of the oral cavity in a first consultation allows lesions to be identified in early stages and early multidisciplinary treatment can improve overall survival. The prognosis of these patients in advanced stages is discouraging. Currently, microvascular surgery is the best therapeutic option, but hemiglossectomy without reconstruction continues to be an acceptable option in our environment, knowing the high costs of the former and the requirement for a larger group of specialists, long surgical times and hospital stays.

Neoplasia de células dendríticas plasmocitoides blásticas. Reporte de un caso / Blastic plasmacytoid dendritic cell neoplasia. Report of a case

RESUMEN La neoplasia de células dendríticas plasmocitoides blásticas (NCDPB) es una malignidad hematológica poco frecuente y generalmente agresiva, por lo cual se requiere su reconocimiento precoz. A continuación, se describe el curso clínico de una paciente de 72 años con NCDPB, en cuyos hallazgos más relevantes destacó la presencia de lesiones cutáneas, organomegalias, infiltración de la médula ósea. Posterior al diagnóstico se indicó quimioterapia sistémica, con buena respuesta, no obstante, a los 2 meses presentó recidiva de lesiones y la paciente falleció. En esta enfermedad es necesario establecer el diagnóstico diferencial con trastornos linfoproliferativos, leucemias linfoides y mieloides agudas, constituyendo el análisis morfológico de las células neoplásicas un aspecto importante para una adecuada orientación diagnóstica.

ABSTRACT Blastic plasmacytoid dendritic cell neoplasia (BCDPN) is a rare and generally aggressive hematological malignancy, which requires early recognition. Below, the clinical course of a 72-year-old patient with NCDPB is described, whose most relevant findings included the presence of skin lesions, organomegaly, and bone marrow infiltration. After the diagnosis, systemic chemotherapy was indicated, with a good response; however, after 2 months the lesions recurred and the patient died. In this disease it is necessary to establish the differential diagnosis with lymphoproliferative disorders, lymphoid and acute myeloid leukemias, with the morphological analysis of the neoplastic cells being an important aspect for adequate diagnostic guidance.

New horizons in sickle cell crisis treatment

Even if life expectancy has increased, sickle cell disease (SCD) still presents difficulties, especially because of the painful episodes that occur frequently and without warning, known as Vaso-occlusive crises (VOCs). These crises are brought on by different cells adhering to one another and obstructing tiny blood veins, which can cause excruciating agony and eventually harm organs and tissues. While the majority of current treatments concentrate on symptom management and pain relief with the use of medications, hydration, and other general approaches, new discoveries about the fundamental mechanisms of VOCs provide intriguing new therapeutic options. With the goal of precisely addressing the pathways causing inflammation and cell adhesion, these cutting-edge treatments may lessen the frequency of VOCs and shield vital organs from harm. Though these treatments provide hope for improved SCD management, careful assessment and analysis of their efficacy and accessibility are necessary to guarantee their general benefit.

Histoplasmosis oral como diagnóstico diferencial de cáncer oral. Serie de casos y revisión de la literatura / Oral histoplasmosis as a differential diagnosis of oral cancer. Case series and literature review

Objetivo: La histoplasmosis es una infección fúngica sistémica prevalente en la región del Río de la Plata. Puede exhibir manifestaciones orales, cutáneas y/o sistémicas. Las lesiones bucales significan un desafío diagnóstico debido a su semejanza clínica con el carcinoma oral de células escamosas (COCE). El objetivo de este trabajo fue presentar una serie de casos de histoplasmosis oral enfatizando la importancia del diagnóstico diferencial clínico con el COCE. Casos clínicos: Se describen casos de histoplasmosis oral diagnosticados en los últimos 5 años en la Cátedra de Estomatología "A" de la Facultad de Odontología de la Universidad Nacional de Córdoba, Córdoba, Argentina. En forma paralela, se realizó una revisión de la literatura de los últimos 10 años. Los casos corresponden a 9 pacientes, 6 varones y 3 mujeres, cuya edad promedio fue de 58,6 años. 4 pacientes eran VIH positivos. Se planteó la sospecha de COCE en 5 pacientes, cuya presentación clínica intraoral consistía en úlceras o lesiones ulcerovegetantes, mayormente únicas, ubicadas en la encía. La revisión bibliográfica arrojó un resultado de 48 artículos que incluyeron 60 casos de histoplasmosis oral, con una prevalencia mayor en hombres y similitudes clínicas con COCE en el 80% de los casos. La lesión más predominante fue la úlcera en el 85% de los casos, ubicada en lengua, seguido por el paladar. El diagnóstico de histoplasmosis oral es desafiante y requiere un amplio diferencial, ya que se asemeja a múltiples patologías, debiendo ser considerada ante lesiones ulcerativas orales. Un diagnóstico preciso, de manera interdisciplinaria, es esencial para un tratamiento efectivo.(AU)

Aim: Histoplasmosis is a systemic fungal infection prevalent in the Río de la Plata region. It could present oral, cutaneous and/or systemic manifestations. Oral lesions represent a diagnostic challenge due to their clinical similarity to oral squamous cell carcinoma (OSCC). The objective of this work is to present a case series of oral histoplasmosis emphasizing the importance of clinical differential diagnosis with OSCC. Clinical cases: Cases of oral histoplasmosis diagnosed in the last 5 years in the Oral Medicine Department "A" of the Facultad de Odontología of the Universidad Nacional de Córdoba, Córdoba, Argentina are discribed. Alongside, a literature review of the last 10 years was carried out. 9 patients are described, 6 men and 3 women, whose average age was 58.6 years. 4 patients were HIV positive. The suspicion of OSCC was raised in 5 patients, whose intraoral clinical presentation consisted of single ulcers or vegetating ulcers, mostly single, located in the gingiva. The literature review included a total of 48 articles with 60 cases of oral histoplasmosis, with a higher prevalence in men and clinical similarities with OSCC in 80% of cases. The most predominant lesion was the ulcer in 85% of the cases, mostly located on the tongue, followed by the palate. The diagnosis of oral histoplasmosis is challenging and requires a wide differential, since it can mimic multiple pathologies, and should be considered in oral ulcerative lesions. An accurate diagnosis, in an interdisciplinary framework, is essential for effective treatment.(AU)

Expression analysis and biological regulation of silencing regulatory protein 6 (SIRT6) in cutaneous squamous cell carcinoma

Abstract Background Cutaneous squamous cell carcinoma (CSCC) is one of the most common types of skin cancer worldwide. Therefore, the identification of biomarkers associated with CSCC progression could aid in the early detection of high-risk squamous cell carcinoma and the development of novel therapeutic strategies. Objective This study aimed to investigate the expression patterns of silent mating type Information Regulation 2 homolog 6 (SIRT6) in CSCC and its clinical significance. Methods The protein expression level of SIRT6 in tissues was detected by immunohistochemistry, and the correlation between SIRT6 expression and clinicopathological parameters in CSCC patients was analyzed. The relative expression of SIRT6 in CSCC cell lineage and tissue specimens was determined by western blotting and PCR. The effect of SIRT6 silencing on cell proliferation was evaluated using cell counting kit 8. Wound healing, transwell method, and flow cytometry were used to investigate the migration, invasion, and cell cycle distribution/apoptosis of CSCC cells after SIRT6 silencing, respectively. Western blot was used to detect the expression of EMT (Epithelial-Mesenchymal Transition), cycle, apoptosis, and other related proteins. Results The high expression of SIRT6 was correlated with the location of cancer tissue and Broder staging in CSCC patients. Knockdown of SIRT6 inhibited the proliferation, migration, invasion and EMT of CSCC cells, and promoted their apoptosis, with cells blocked in G1 phase. Study limitations No animal experiments were conducted to further verify the results. Conclusion Decreased expression of SIRT6 can inhibit the occurrence and development of CSCC.

Primary Retroperitoneal Lymph Node Dissection for Clinical Stage II A/B Seminomas: A Systematic Review and Meta-Analysis

ABSTRACT Introduction Chemotherapy and radiation therapy are considered standard treatments for stage II seminoma patients; however, these therapies are associated with long-term toxicities. Recently, retroperitoneal lymph node dissection has emerged as an alternative strategy, and the first three phase II trials were published in 2023 with promising results. The present study conducted a systematic review and meta-analysis to evaluate this surgery as an alternative treatment for stage IIA/B seminoma patients. Purpose Seminomas are the most common testicular tumors, often affecting young adult males. Standard treatments for stage II seminomas include chemotherapy and radiation therapy, but these therapies are associated with long-term toxicities. Thus, identifying alternative strategies is paramount. Herein, we conducted a systematic review and meta-analysis to appraise the efficacy and safety of retroperitoneal lymph node dissection (RPLND) for treating this condition. Methods We systematically searched the PubMed, Embase, and Cochrane databases for studies evaluating RPLND as a primary treatment for stage II A/B seminomas. Using a random-effects model, single proportion and means and pooled 2-year recurrence-free survival rates with hazard rates and 95% CI were calculated. Results Seven studies were included, comprising 331 males with stage II seminomas. In the pooled analysis, the recurrence rate was 17.69% (95% CI 12.31-24.75), and the 2-year RFS rate was 81% (95% CI 0.77-0.86). The complication rate was 9.16% (95% CI 6.16-13.42), the Clavien-Dindo > 2 complication rate was 8.83% (95% CI 5.76-13.31), and the retrograde ejaculation rate was 7.01% (95% CI 3.54-13.40). The median operative time was 174.68 min (95% CI 122.17-249.76 min), median blood loss was 105.91 mL (95% CI 46.89-239.22 mL), and patients with no evidence of lymph node involvement ranged from 0-16%. Conclusions Primary RPLNDs for treating stage IIA/B seminomas have favorable RFS rates, with low complication and recurrence rates. These findings provide evidence that this surgery is a viable alternative therapy for these patients.

En la relación de pareja, el empleo del celular puede llegar a ocasionar conflictos, lo que afectaría la valoración de la unión conyugal. Objetivo: Determinar la asociación entre la satisfacción con la relación de pareja y los conflictos por el uso del celular en adultos peruanos. Materiales y Métodos. Estudio cuantitativo, de tipo no experimental, transversal y correlacional. La muestra fue constituida por 325 adultos peruanos mediante un muestreo no probabilístico. La información se recolectó mediante la técnica de la encuesta y como instrumento dos cuestionarios, la Escala de Valoración de la Relación propuesto por Hendrick y la Escala de Conflictos Relacionados al uso del celular de Roberts y David. Resultados. La satisfacción con la relación de pareja fue mayormente moderada para el 43,5%. Entre tanto, indicaron algún nivel de conflicto por el uso del celular el 72,9%. Además, no se encontró diferencias significativas en la satisfacción con la relación de pareja según el sexo. Conclusiones. Existe relación negativa moderada y significativa entre la satisfacción con la relación de pareja y los conflictos por el uso del celular en adultos peruanos (rs= -0.456), donde se alcanzó una p=0,000 (<0.05). De esta manera se sostiene que a mayor satisfacción, menores serán los conflictos percibidos por el uso del celular.

In the couple relationship, the use of cell phones can lead to conflicts, which would affect the assessment of the marital union. Objective: To determine the association between satisfaction with the couple relationship and conflicts due to cell phone use in Peruvian adults. Materials and Methods. Quantitative, non-experimental, cross-sectional and correlational study. The sample consisted of 325 Peruvian adults through non-probabilistic sampling. The information was collected using the survey technique and two questionnaires as instruments, the Relationship Assessment Scale proposed by Hendrick and the Conflicts Related to Cell Phone Use Scale by Roberts and David. Results. Satisfaction with the couple relationship was mostly moderate at 43.5%. Meanwhile, 72.9% indicated some level of conflict due to cell phone use. Furthermore, no significant differences were found in satisfaction with the couple relationship according to sex. Conclusions. There is a moderate and significant negative relationship between satisfaction with the couple relationship and conflicts due to cell phone use in Peruvian adults (rs= -0.456), where p=0.000 (<0.05) was reached. In this way, it is argued that the greater the satisfaction, the fewer the perceived conflicts due to cell phone use.

Resultados. A satisfação com o relacionamento conjugal foi predominantemente moderada em 43,5%. Enquanto isso, 72,9% indicaram algum nível de conflito devido ao uso de celular. Além disso, não foram encontradas diferenças significativas na satisfação com o relacionamento conjugal de acordo com o sexo. Conclusões. Existe uma relação negativa moderada e significativa entre a satisfação com o relacionamento conjugal e os conflitos devido ao uso de celular em adultos peruanos (rs= -0,456), onde foi atingido p=0,000 (<0,05). Dessa forma, argumenta-se que quanto maior a satisfação, menores serão os conflitos percebidos devido ao uso de celular.

Morphological and Morphometric Analysis, Apoptosis and Oxidative Stress Study in Hep 2 Cells Treated by Resveratrol or Quercetine / Análisis Morfológico y Morfométrico, Estudio de Apoptosis y Estrés Oxidativo en Células Hep 2 Tratadas con Resveratrol o Quercetina

SUMMARY: Resveratrol (RES) and quercetine (QRC), is a promising agent relevant for both cancer chemoprevention and treatment via several signaling pathways, involved in their anticancer activity related to its chemotherapeutic potential, associated with the induction of ROS generation in cancer cells, leading to apoptosis. In our study, we have summarized the mechanisms of action of RES and QRC, and their pharmacological implications and potential therapeutic applications in cancer therapy. After treatment of Hep 2 cells with QRC or RES, the death pathways such as the cytochrome c release, ERK1/2 and IRS-1 pathways were upregulated, while cell survival pathway, including PI3K/AKT were downregulated. The RES and QRC caused oncosis, cells hypertrophy, hypercondensatin of chromatin, rupture of the plasma membrane and nuclear membrane, and formation of apoptotic bodies. Morphometric measurements of some cellular and nuclear parameters showed that RES and QRC induced an increase in cells and nuclear size, the nucleocytoplasmic ratio remained below 1 (N-Cyt R < 1), sign of low nuclear activity. The RES and QRC induced apoptosis of Hep2 cells by increasing of oxidative stress markers, MDA, and by modulating detoxifying enzymes, CAT and SOD. Our study results prove antiproliferative and proapoptotic properties of quercetin and resveratrol with regard to larynx cancer.

Resveratrol (RES) y quercetina (QRC), es un agente prometedor y relevante tanto para la quimioprevención como para el tratamiento del cáncer a través de varias vías de señalización, involucrado en su actividad anticancerígena relacionada con su potencial quimioterapéutico, asociado con la inducción de la generación de especies reactivas del oxígeno (ROS) en células cancerosas, lo que lleva a apoptosis. En nuestro estudio, hemos resumido los mecanismos de acción de RES y QRC, y sus implicaciones farmacológicas y posibles aplicaciones terapéuticas en la terapia del cáncer. Después del tratamiento de las células Hep 2 con QRC o RES, las vías de muerte, tal como la liberación de citocromo c, las vías ERK1/2 e IRS-1, se regulaban positivamente, mientras que la vía de supervivencia celular, incluida PI3K/AKT, se regulaba negativamente. El RES y el QRC provocaron oncosis, hipertrofia celular, hipercondensación de la cromatina, rotura de la membrana plasmática y nuclear y formación de cuerpos apoptóticos. Las mediciones morfométricas de algunos parámetros celulares y nucleares mostraron que RES y QRC indujeron un aumento en las células y el tamaño nuclear, la proporción nucleocitoplasmática se mantuvo por debajo de 1 (N- Cyt R <1), signo de baja actividad nuclear. RES y QRC indujeron la apoptosis de las células Hep2 aumentando los marcadores de estrés oxidativo, MDA, y modulando las enzimas desintoxicantes, CAT y SOD. Los resultados de nuestro estudio demuestran las propiedades antiproliferativas y proapoptóticas de la quercetina y el resveratrol con respecto al cáncer de laringe.

Non-Hodgkins lymphoma of bilateral eyelids with basal cell carcinoma of nose: a rare case report

Malignant tumours affecting the eyelid mainly include basal cell carcinoma. Non-Hodgkin抯 lymphoma may occur in almost any part of the body and should be considered in the differential diagnosis of extra lymphoid tumours. Non- Hodgkin抯 lymphoma of the eyelid is rare. Rare diseases should be considered in differential diagnoses because they have the tendency for rapid systemic involvement and they may require treatments that are different from the other common diseases. Basal cell carcinoma occurs most frequently at sun-exposed sites, most commonly in the head and neck regions. The aim of any therapy selected for BCC treatment involving the head and neck is to ensure complete removal, functional preservation, and a good cosmetic outcome. Here, we reported a case of a 70-year-old female with non-Hodgkin lymphoma of eyelids followed by basal cell carcinoma of the nose treated with multimodality approach.

The unusual presentation of sertoli-leydig cell tumor: a case report

Sertoli cell tumor is very rare variety of ovarian Sertoli?Leydig cell tumors. Due to nonspecific clinical and imaging features, diagnosis is often made after histopathological examination. Sertoli cell tumors usually presents with the features of virilization. The prognosis is excellent as most are detected in the early stages and surgical resection is often curative in most cases. Here we present a case of Sertoli Cell tumor, where no feature of virilization was present.

Recurring basal cell carcinoma involvingexclusively intra-oral mucosa: a case report

Basal cell carcinoma (BCC) is the most common skin cancer, but oral involvement is extremely rare. Here, we showed a case of a 71-year-old Caucasian male patient presenting an asymptomatic submucosal nodule in the left buccal mucosa on the same side of a previous BCC skin lesion. Intraoral examination revealed a circumscribed sessile and fibrous mass covered by normal mucosa. An incisional biopsy was performed. Microscopically, the lesion showed uniform, ovoid, dark-staining basaloid cells with medium-sized nuclei and little cytoplasm arranged in islands and strands, invading the underlying connective tissue. These islands demonstrated palisading of the peripheral cells and occasionally central areas with epidermoid differentiation. The final diagnosis was nodular basal cell carcinoma. Although uncommon, recurrent BCC may occur in the oral cavity. (AU)

A peak into metastatic Leydig cell tumor: a rare case report

Testicle tumors are a rare entity among men population, comprising 1-1.5% of all cancers. The Sex cord Stromal tumors contribute just 4% of all testicular cancers, only 10% of them are malignant. Most common sex cord-stromal tumors are the Leydig cell tumor, comprising of 75 to 80% of the total. Incidence is bimodal involving children and adults between 30 and 60 years. The commonest metastatic sites are regional lymph nodes, lung, liver, and bones. Here, we report a case of late metastatic relapsed Leydig cell tumor in a 38-year-old male. Patients with metastatic Leydig cell tumors have poor prognosis and standard treatment recommendations are unclear.

Management of facial bacal cell carcinoma in rural hospital: a case report

Basal cell carcinoma is usually a slow-growing tumor for which metastases are rare. Basal Cell Carcinoma is the most common type of skin cancer around 75-80%. We present the case of A 87-year-old woman presented with a chief complaint of a reddish-brown nodule on the right side of her face. The complaint has been about 4 months, initially small in size as a mole but grew progressively to its current size. It is known that his daily work is as a farmer. However, one of the main problems of BCC is the cosmetic appearance, especially in the facial area.
