RESUMO

The lymphocyte-depleted classic Hodgkin lymphoma (LDCHL), the rarest subtype of classic Hodgkin lymphoma (CHL), is usually diagnosed at an advanced stage (stage IV) and one that unusually involves the liver, causing a rapidly progressive clinical course. We describe a 40-year-old immunocompromised man presenting with a progressive non-cholestatic jaundice and intermittent fever. The abdominal ultrasonography revealed a nodular liver with coarse echotexture and periportal hypodensities. The thoracic and abdominal contrast-enhanced computed tomography revealed right cervical and paraaortic lymphadenopathy, hepatosplenomegaly, diffuse mural thickening of duodenal and jejunal loops, and bilateral lobulated kidneys. Subsequently, he succumbed to his illness secondary to refractory septic shock. On postmortem examination, he was diagnosed with classic Hodgkin lymphoma (lymphocyte-depleted type) involving paraaortic and mediastinal lymph nodes based on morphology and immunochemistry findings. The lymphomatous process involved the liver (causing multiacinar confluent hepatic necrosis) and spleen, both showing tuberculous foci. This autopsy case depicts an uncommon case of acute liver failure due to infiltration of the liver by LDCHL in an HIV-infected patient. The findings of angiotropism and angioinvasion establish the pathological mechanism of liver failure (hepatocellular necrosis) in such cases.

RESUMO

OBJECTIVE: To investigate attention deficit and hyperactivity disorder (ADHD) symptoms and impulsivity among individuals diagnosed with opioid use disorder (OUD) who also exhibit symptoms of problematic internet use (PIU). METHODS: The study involved the participation of 360 patients with OUD enrolled at an alcohol and drug addiction treatment center (ADATC) from October to December 2022. Various assessment tools were administered, including Young's Internet Addiction Scale (YIAS), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Barratt Impulsiveness Scale (BIS), and Adult ADHD Self-Report Scale (ASRS). PIU was identified by YIAS scores equal to or exceeding 50. RESULTS: Most participants diagnosed with OUD had comorbid PIU, with high levels of depression, anxiety, and ADHD symptoms. Both BDI and BAI scores were significantly increased in the PIU group compared to the non-PIU group (p < 0.001). Significant differences were observed in BIS Motor Impulsivity, Attentional Impulsivity, and total scores, indicating higher impulsivity in the PIU group (all p < 0.001). Additionally, higher ASRS scores were found in the PIU group (p < 0.001). CONCLUSION: These findings highlight the importance of addressing PIU and comorbidities in OUD treatment. Interventions targeting ADHD symptoms and emotional well-being may benefit PIU management.

RESUMO

SUMMARY OBJECTIVE: The objective of this study was to determine the effects of listening to nature sounds alone and virtual reality plus listening to nature sounds on pain and anxiety in hysterosalpingography. METHODS: This three-arm parallel randomized controlled trial included 135 (45 in each group) women who underwent hysterosalpingography in Turkey. The virtual reality+nature sounds group viewed a nature video with virtual reality glasses and listened to nature sounds during hysterosalpingography, whereas the nature sounds group only listened to nature sounds. The control group received only routine care. RESULTS: During hysterosalpingography, women in virtual reality+nature sounds group experienced less pain than those in control group (p=0.009). After hysterosalpingography, pain levels were lower in both virtual reality+nature sounds group and nature sounds group than in control group (p=0.000 and p=0.000, respectively), anxiety levels were lower in virtual reality+nature sounds group than in nature sounds group and control group (p=0.018 and p=0.000, respectively), and anxiety levels were lower in nature sounds group than in control group (p=0.013). CONCLUSION: Virtual reality with nature content plus listening to nature sounds and only listening to nature sounds are effective in reducing pain and anxiety related to hysterosalpingography procedures in women. Compared with only listening to nature sounds, virtual reality plus listening to nature sounds further reduced hysterosalpingography-related pain and anxiety.

RESUMO

ABSTRACT Purposes: This study aims to assess and compare the postoperative visual and topographic outcomes, complications, and graft survival rates following deep anterior lamellar keratoplasty and penetrating keratoplasty in patients with macular corneal dystrophy. Methods: In this study we enrolled 59 patients (23 male; and 36 female) with macular corneal dystrophy comprising 81 eyes. Out of these, 64 eyes underwent penetrating keratoplasty, while 17 eyes underwent deep anterior lamellar keratoplasty. The two groups were analyzed and compared based on best-corrected visual acuity, corneal tomography parameters, pachymetry, complication rates, and graft survival rates. Results: After 12 months, 70.6% of the patients who underwent deep anterior lamellar keratoplasty (DALK) and 75% of those who had penetrating keratoplasty (PK) achieved a best-corrected visual acuity of 20/40 or better (p=0.712). Following surgery, DALK group showed lower front Kmean (p=0.037), and Q values (p<0.01) compared to the PK group. Postoperative interface opacity was observed in seven eyes (41.2%) in the DALK group. Other topography values and other complications (graft rejection, graft failure, cataract, glaucoma, microbial keratitis, optic atrophy) did not show significant differences between the two groups. The need for regrafting was 9.4% and 11.8% in the PK and DALK groups, respectively (p=0.769). Graft survival rates were 87.5% and 88.2% for PK and DALK; respectively (p=0.88 by Log-rank test). Conclusion: Both PK and DALK are equally effective in treating macular corneal dystrophy, showing similar visual, topographic, and survival outcomes. Although interface opacity occurs more frequently after DALK the visual results were comparable in both groups. Therefore, DALK emerges as a viable surgical choice for patients with macular corneal dystrophy without Descemet membrane involvement is absent.

RESUMO

ABSTRACT Objective: To evaluate the pulpal temperature changes due to the polymerisation of resin and glass ionomer-based materials in dentine thicknesses in immature permanent teeth with open apices. Material and Methods: Forty extracted sound human third molar teeth with open apices were included. The width of the cavities prepared on the occlusal surface was 4×5 mm. The depth was 2 mm in the resin groups. 4 mm in the groups in which glass ionomer liner was applied before composite restoration. The coronal parts of the samples were then placed on an acrylic plate with three gaps for feeding-extraction needles and the thermocouple. The temperature changes were recorded. The data was analyzed by SPSS. Statistical significance was accepted as p<0.05. Results: The temperature increase in the group of 1 mm remaining dentin thickness revealed higher results than the values detected from the 2 mm group (1.01 °C) (p=0.00). The mean values (1.49 °C, 1mm) of temperature changes in only glass ionomer applied group were lower than the avarage values (2.210°C, 1mm) determined in the polymerization process of resin composites with light-emitting diode devices. Conclusion: In a remaining dentin thickness of 1 mm in teeth with open apices, using a glass ionomer liner might be a useful effort for protecting the pulp from the heat generated by polymerisation devices.

RESUMO

OBJECTIVE: This study aims to examine the effect of comfort theory-based nursing care on pain and comfort in women undergoing hysterosalpingography. METHODS: This randomized control trial was conducted on 126 women (42 in each intervention and control group). Virtual reality glasses group (n=42), mobile-assisted education group (n=42), and control group (n=42). The control group received only routine care. Comfort levels were evaluated at the beginning and end of the study using the General Comfort Scale and pain levels evaluated at the beginning and end of the study using the Visual Analog Scale. RESULTS: The comfort theory-based nursing care (virtual reality glasses and mobile-assisted education group) was effective in increasing women's comfort with painful invasive procedures such as hysterosalpingography and reducing pain. CONCLUSION: It is recommended that a nurse be present in the hysterosalpingography process, providing nursing care services continuously and introducing this program to working nurses.Clinical Trial Registration Number: NCT04676932.

RESUMO

Extranodal NK/T- cell lymphoma (ENKTCL) is an aggressive lymphoma driven by Epstein-Barr virus (EBV) infection in genetically susceptible individuals. It was historically called a lethal midline granuloma. Due to the angio-destructive nature of ENKTCL, lymphoma cells are often accompanied and masked by necrosis and dense inflammation in the biopsy. Further, the biopsy may show vasculitis, which can mimic granulomatosis with polyangiitis. Due to these masquerades, ENKTCL is often misdiagnosed in the biopsy. Several biopsies may be required to establish the diagnosis. We describe the clinical course and autopsy findings of a young female who presented with a hard-palate ulcer. Antemortem biopsies failed to establish the diagnosis. The autopsy revealed an advanced nasal subtype of Extranodal NK/T-cell lymphoma with dissemination to the kidneys, adrenals, liver, spleen, and small intestine.

RESUMO

Acute erythroid leukemia (AEL) is an exceedingly uncommon but distinct hematological malignancy that shows neoplastic proliferation of erythroid precursors with maturation arrest and no significant myeloblasts. We describe an autopsy case of this rare entity in a 62-year-old man with co-morbidities. He underwent a bone marrow (BM) examination for pancytopenia during the first outpatient department visit, which revealed an increased number of erythroid precursors with dysmegakaryopoiesis suggesting the possibility of Myelodysplastic syndromes (MDS). Thereafter, his cytopenia got worsened, warranting blood and platelet transfusions. Four weeks later on the second BM examination, AEL was diagnosed based on morphology and immunophenotyping. Targeted resequencing for myeloid mutations revealed TP53 and DNMT3A mutations. He was initially managed along febrile neutropenia with the stepwise escalation of antibiotics. He developed hypoxia attributed to anemic heart failure. Subsequently, he had hypotension and respiratory fatigue pre-terminally and succumbed to his Illness. A complete autopsy showed infiltration of various organs by AEL and leukostasis. Besides, there was extramedullary hematopoiesis, arterionephrosclerosis, diabetic nephropathy (ISN-RPS class II), mixed dust pneumoconiosis, and pulmonary arteriopathy. The histomorphology of AEL was challenging, and the differential diagnoses were many. Thus, this case highlights the autopsy pathology of AEL, an uncommon entity with a strict definition, and its relevant differentials.

RESUMO

OBJECTIVE: This study aims to examine the effect of telecounseling in reducing the anxiety and depression experienced by pregnant women. METHOD: This randomized control trial was conducted on 100 pregnant women (50 in each intervention and control group). The intervention group received telecounseling with regard to the mother and the fetus as needed between 08:00 h and 20:00 h for 6 weeks at home. The control group received only routine care. Anxiety and depression levels were evaluated at the beginning and end of the study using the Hospital Anxiety Depression Scale. RESULTS: Anxiety and depression levels were found to be lower in the intervention group than in the control group (p<0.001). In the control group, the anxiety score increased from 5.62 to 7.16, and the depression score increased from 4.92 to 5.76 without any intervention (p<0.001). CONCLUSION: This study shows that telecounseling may have an effect on reducing the level of anxiety and depression of pregnant women.

RESUMO

Background Cataracts are the leading global cause of preventable blindness. Despite the high prevalence of cataracts in rural Ecuadorian communities, no community-wide educational efforts on the impact of cataract-related blindness have been attempted. This study used an educational brochure to assess individual knowledge of cataract blindness before and after the distribution of the brochure. Methods We conducted electronic surveys with 100 patients over the age of 18 who visited the Fundacion Internacional Buen Samaritano Paul Martel (FIBUSPAM) clinic serving the Chimborazo region of Ecuador. Participation in the study included an introduction and written consent followed by a pre-survey. Every patient was given a brochure. After reviewing the brochure, patients were then asked to complete the same survey again. Each survey question received one mark. Knowledge was considered "good" if the subject correctly answered four out of seven questions and "poor" if they scored ≤3. Results Of the 100 patients, 21 had poor knowledge surrounding cataracts. Cataract awareness was lowest in the group without formal education (50%). In addition, 17 participants demonstrated poor knowledge before the informational brochure was distributed, and all improved to "good" knowledge after. Following brochure distribution, there was an improved knowledge of cataract anatomy (correct answer: 32.9% to 94.6%), treatment of cataracts (80% to 95.9%), cataract symptoms (36.7% to 95.9%), age at risk (88.8% to 97.3%), and relationship to blindness (93.5% to 98.6%). In contrast, overall knowledge of the risk factors for cataracts (46.8% to 37%) and prevention of the onset of the cataract (81.3% to 77%) slightly decreased after the brochure was given. Overall, the increase in the number of correct answers after the brochure was not significant (p = 0.25). Conclusions To our knowledge, this is a rare study to assess the effect of informational brochures on cataract knowledge in rural Ecuador. This study was limited by selection bias and did not look at the long-term recall of knowledge. The results of this study suggest that brochures can improve health awareness; however, brochures alone may not be enough. Additional assessments on the use of oral and visual aids are needed. Health education efforts should go beyond simple brochures and focus on innovative strategies to improve health education and communication efforts.

RESUMO

La inseguridad alimentaria (INSA) es la condición que resulta de un acceso incierto o nulo a alimentos nutricionalmente adecuados socialmente aceptables y/o insuficiente ingestión de alimentos. Las causas de la INSA son múltiples y difieren en cada país, entre ellas están inadecuado acceso, y disponibilidad a los alimentos nutricionalmente adecuados y a los capitales de desarrollo. Según los resultados de la Encuesta Nacional de Condiciones de Vida del 2014, la INSA afecta a más de la mitad de la población guatemalteca con repercusiones en su calidad de vida y desarrollo. El objetivo de la investigación fue determinar el nivel de INSA en hogares de los 29 municipios pertenecientes a 12 departamentos de cobertura del EPS de la Universidad de San Carlos de Guatemala. Se realizó un estudio de tipo cuantitativo, descriptivo, transversal, utilizando la metodología de recolección, validación y análisis de información establecida en el Manual de la Escala Latinoamericana y Caribeña de Seguridad Alimentaria (ELCSA). La muestra fue de 2,750 hogares, obtenida por medio de un muestreo probabilístico para poblaciones finitas. Los datos analizados fueron desagregados según sexo y edad de jefe de hogar, lugar de residencia, número de miembros en el hogar y presencia de menores de 18 años. La investigación mostró que, al momento de la entrevista, 2,035 (74%) [72.3, 75.7] hogares fueron clasificados en situación de INSA. Se presentó un mayor porcentaje de INSA en los hogares del área rural (85% [82.5, 87.4]) y en los hogares con niños menores de 18 años (80% [78.0, 81.5]). También se observó que, a mayor número de miembros del hogar, mayor porcentaje de INSA. Con los resultados obtenidos, se pretende motivar la implementación de estrategias que coadyuven a mejorar la situación de INSA en la población.


Food insecurity (FI) is the condition that results from uncertain or no access to socially acceptable, nutritionally adequate foods and/or insufficient food intake. The causes of FI are multiple and differ in each country, among them are inadequate access and availability to adequate nutritional foods and development capital. According to the results of the 2014 National Survey of Living Conditions, FI affects more than half of the Guatemalan population.The objective of the research was to determine the level of FI at household level of the 29 municipalities belonging to 12 departments covered by the Nutrition Supervised Professional Practice of the University of San Carlos of Guatemala, through a quantitative, descriptive, cross-sectional study, using the collection, validation and analysis of information established in the Manual of the Latin American and Caribbean Food Security Scale. The sample was 2,750 households, obtained by means of a probabilistic sampling for finite populations. The data analyzed were disaggregated according to the sex and age of the head of the household, place of residence, number of members in the household, and presence of children under 18 years of age. The investigation showed that, at the time of the interview, 2,035 (74%) [72.3, 75.7] households were classified as FI. There was a higher percentage of FI in households in rural areas (85% [82.5, 87.4]) and in households with children under 18 years of age (80% [78.0, 81.5]). It is intended that the results of this study contribute to motivate the implementation of strategies that help to improve the situation of FI in the evaluated population.

RESUMO

OBJECTIVE: This study aimed to investigate female sexual function in patients with type 1 diabetes by comparing female sexual function index scores between women with and without type 1 diabetes. METHODS: A total of 62 women with type 1 diabetes and 69 age-matched women without diabetes but with similar backgrounds were enrolled in the patient and control groups, respectively. All participants were sexually active and had no systemic diseases other than diabetes in the patient group. RESULTS: The frequency of female sexual dysfunction was significantly higher, and the mean female sexual function index score was significantly lower in women with diabetes compared to the control group (p=0.01). There was a significant relationship between sexual dysfunction and duration of diabetes, glycosylated hemoglobin test, and body mass index (p<0.05). CONCLUSION: This study demonstrates that female sexual dysfunction is more common among women with type 1 diabetes than among women without type 1 diabetes. Patients with type 1 diabetes should be evaluated in terms of sexual health. Health professionals should give more attention to and provide guidance regarding sexual function in women with type 1 diabetes.

RESUMO

Abstract Background Direct immunofluorescence (DIF) panels are usually ordered for clinically suspected cutaneous vasculitis, but their positivity rate is variable, and their prognostic significance is not clear to date. Objective The study aims to investigate the systemic involvement rate in leukocytoclastic vasculitis (LCV) patients and the potential clinical and laboratory associations with systemic involvement, including DIF findings. Methods A retrospective study of patients with histopathologically proven cutaneous LCV examined in the dermatology department between 2013 and 2017 was performed. Results Of the 81 patients (mean age, 50.6 years), 42 (52%) were male. The mean time between the appearance of skin lesions and biopsy was 23.1 days, ranging from 2 to 180 days. DIF showed overall positivity of 90.1%, and C3 was the most frequent immunoreactant (82.7%). Any kind of extracutaneous involvement was present in 47 (58%) of patients, with renal involvement being the most frequent (53.1%), followed by articular (18.5%) and gastrointestinal (11.1%) involvement. The presence of renal disease was associated with the detection of IgG in the lesional skin (p = 0.017), and with the absence of IgM in the lesional skin (p = 0.032). There was a significant association between C3 deposition and joint involvement (p = 0.05). Study limitations This is a single-center study with a retrospective design. Conclusion DIF seems to be a useful ancillary diagnostic tool in the evaluation of cutaneous vasculitis, but the relationship between DIF findings and systemic involvement needs to be further elucidated due to contradictory data in the current literature.
