Relación entre sobrecompromiso y síntomas somáticos en enfermeras de un hospital de II nivel en Perú

Objetivo : Determinar la relación entre sobrecompromiso y síntomas somáticos en enfermeras de un hospital de II nivel en Perú. Material y métodos : Investigación observacional, transversal y correlacional, con una muestra probabilística de 106 enfermeras. Se aplicó el Cuestionario de Siegrist y Meter para medir sobrecompromiso y desequilibrio esfuerzo recompensa, y el Cuestionario de Salud (PHQ15) para síntomas somáticos. Se construyó un modelo de regresión logística, considerando variables sociodemográficas y laborales. Resultados : En las enfermeras que presentaron síntomas somáticos moderados-graves, el 68,3% tuvo un nivel de sobrecompromiso alto. El modelo de regresión mostró que sobrecompromiso (OR = 6,25, p < 0,01), tiempo laboral (OR = 0,74, p < 0,01) y la condición de personal (nombrado o contratado, OR = 49,20, p < 0,01) influyeron en el nivel de síntomas somáticos. El modelo discriminó correctamente el 79% (IC 95%: 0,70 - 0,88) de los casos con síntomas somáticos, siendo el valor 0,43, el que se usò para la clasificaciòn en leve-mìnimo y moderado-grave con una sensibilidad de 73% y especificidad del 74%. Conclusión : Se corroboró una relación significativa entre sobrecompromiso y síntomas somáticos, con un modelo predictivo que logró un nivel elevado de discriminación para identificar personal de enfermería en riesgo.

SUMMARY Objective : To determine the relationship between over commitment and somatic symptoms among nurses in a type II hospital in Peru. Methods : A cross-sectional study with a probabilistic sample of 106 participants was carried-out. The Siegrist and Meter questionnaire was applied to measure over commitment and imbalance effort-recompense and the Health Questionnaire (PHQ15) was applied to evaluate somatic symptoms. A logistic regression model was built considering sociodemographic and labor variables. Results : The 68.3% of nurses that presented with moderate to severe somatic symptoms had a high level of over commitment. The regression model showed that over commitment (OR = 6.25, p < 0.01), time in the working place (OR = 0.74, p < 0.01) and labor status (staff or hired temporarily OR = 49.20, p < 0.01) influenced the level of somatic symptoms. The model discriminated well the 79% (95% CI: 95%: 0.70 - 0.88) of somatic cases. A value of 0.43 was selected to discriminate between mild to moderate-severe with a sensitivity of 73% and 74% specificity. Conclusions : A signifcant correlation between over commitment and somatic symptoms ws found. The regression model attained a high discriminative level to identify nurses at risk.

A retrospective multicenter study of oral and maxillofacial lesions in older people

Abstract Few studies on the distribution of oral diseases in older people are available in the literature. This study aimed to investigate the prevalence and demographic characteristics of oral and maxillofacial lesions in geriatric patients (age ≥ 60 years). A retrospective descriptive cross-sectional study was performed. Biopsy records were obtained from archives of three Brazilian oral pathology centers over a 20-year period. Data on sex, age, anatomical site, skin color, and histopathological diagnosis were collected and analyzed. Pearson's chi-square test was used to evaluate differences in the frequency of the different oral and maxillofacial lesion groups. A total of 7,476 biopsy records of older patients were analyzed. Most cases were diagnosed in patients aged 60 to 69 years (n = 4,487; 60.0%). Females were more affected (n = 4,403; 58.9%) with a female-to-male ratio of 1:0.7 (p < 0.001). The tongue (n = 1,196; 16.4%), lower lip (n = 1,005; 13.8%), and buccal mucosa (n = 997; 13.7%) were the most common anatomical sites. Reactive and inflammatory lesions (n = 3,840; 51.3%) were the most prevalent non-neoplastic pathologies (p < 0.001), followed by cysts (n = 475; 6.4%). Malignant neoplasms were more frequent (n = 1,353; 18.1%) than benign neoplasms (n = 512; 6.8%). Fibrous/fibroepithelial hyperplasia (n = 2,042; 53.2%) (p < 0.001) and squamous cell carcinoma (n = 1,191; 88.03%) (p < 0.001) were the most common oral lesions in older adults. Biopsy data allow the accurate characterization of the prevalence of oral and maxillofacial lesions, supporting the development of public health policies that can enable the prevention, early diagnosis, and appropriate treatment of these lesions. Also, they bring valuable information that helps dentists and geriatricians diagnose these diseases.

Efecto del programa SERUMS en la equidad de la distribución de recursos humanos del primer nivel de atención en Perú

Introducción. La adecuada dotación y distribución con equidad de recursos humanos son fundamentales para el desempeño del sistema de salud, especialmente en el primer nivel de atención. El Programa Servicio Rural y Urbano Marginal (SERUMS) es la principal estrategia desarrollada por el Estado peruano para este fin. Objetivo. Describir el efecto de la dotación de médicos, enfermeros y obstetras del Programa SERUMS en la equidad de la distribución de recursos humanos en el primer nivel de atención. Métodos. Estudio observacional, descriptivo y transversal, de carácter censal con base en el Registro Nacional de Personal de Salud - INFORHUS, agosto 2019. Se aplicó indicadores de dotación, se verificó si existe diferencia entre la distribución porcentual de profesionales SERUMS y no SERUMS, se calculó la densidad (profesionales/10 000 hab. a nivel departamental, quintil de pobreza y ruralidad) y coeficientes de Gini (departamental). Resultados. La población estuvo constituida por 6037 profesionales SERUMS y 27 495 no SERUMS. El Programa SERUMS incrementó de manera importante la dotación y densidad de profesionales en casi todas las regiones del país. En 5 regiones los profesionales SERUMS representaron más del 50% de la dotación. Incrementos importantes se encontraron en el análisis por quintil de pobreza y en el ámbito rural, especialmente en la dotación de médicos. El programa SERUMS evidenció una mayor desigualdad en su distribución, según los coeficientes de Gini, a favor de las poblaciones más vulnerables. Conclusiones. El Programa SERUMS incrementa de manera importante la dotación y densidad de profesionales, especialmente en los distritos más pobres del Perú.

Introduction. The adequate allocation and equitable distribution of human resources are essential for the health system›s performance, especially at the first level of care. The Rural and Urban Marginal Service Program (SERUMS) is the primary strategy developed by the Peruvian State for this purpose. Objective. To describe the effect of the number of doctors, nurses, and midwives of the SERUMS Program on the equity of the distribution of human resources at the primary care level. Methods. Observational, descriptive, and cross-sectional study of a census nature based on the National Registry of Health Personnel - INFORHUS, August 2019. Staffing indicators were applied, it was verified if there is a difference between the percentage distribution of SERUMS and non-SERUMS professionals, density (professionals per 10 000 inhabitants at the departmental level, poverty quintile, and rurality), and Gini coefficients (departmental) were calculated. Results. The population consisted of 6037 SERUMS professionals and 27 495 non-SERUMS professionals. The SERUMS Program significantly increased the number and density of professionals in almost all departments. In 5 regions, SERUMS professionals represented more than 50% of the workforce. Significant increases in the number of doctors were found in the poverty quintile and rural areas analysis. According to the Gini coefficients, the SERUMS program showed greater inequality in its distribution in favor of the most vulnerable populations. Conclusions. The SERUMS Program significantly increases the number and density of healthcare professionals, especially in the poorest districts of Peru.

FoxP3+ regulatory T cells in oral tongue squamous cell carcinoma in young and older patients

Abstract Regulatory T (Treg) cells can suppress antitumor immune response, but little is known about possible age-related differences in the number of these cells in the microenvironment of oral tongue squamous cell carcinoma (OTSCC). The aim of this study was to determine the number of FoxP3+ Treg cells in the microenvironment of OTSCC in young (≤ 45 years) and older (≥ 60 years) patients, and to correlate the findings with clinicopathological parameters (sex, tumor size/extent, regional lymph node metastasis, clinical staging, and histopathological grade of malignancy). Forty-eight OTSCCs (24 diagnosed in young patients and 24 diagnosed in older patients) were selected. Lymphocytes exhibiting nuclear immunopositivity for FoxP3 were quantified at the tumor invasive front and the results were analyzed statistically using the non-parametric Mann-Whitney test. FoxP3+ lymphocytes were observed in all cases assessed. The number of FoxP3+ lymphocytes in OTSCC tended to be higher in older patients (p = 0.055). Analysis of OTSCC in males and in early clinical stages revealed a higher number of Treg cells in older patients than in young ones (p < 0.05). In older patients, the number of Treg cells tended to be higher in smaller tumors (p = 0.079). Tumors with intense inflammatory infiltrate exhibited a larger number of Treg cells, both in young (p = 0.099) and older patients (p = 0.005). The results suggest a greater participation of Treg cells in immunoinflammatory responses in the microenvironment of OTSCC in older patients, particularly in males and in early stages.

Immunoexpression of human leukocyte antigen-DR in actinic cheilitis and lower lip squamous cell carcinoma

Abstract The aim of this study was to evaluate the immunoexpression of human leukocyte antigen-DR (HLA-DR) in actinic cheilitis (AC) and lower lip squamous cell carcinoma (LLSCC), and to correlate the findings with clinical (tumor size/extent, regional lymph node metastasis, and clinical stage) and histopathological (grade of epithelial dysplasia and inflammatory infiltrate for AC and histopathological grade of malignancy for LLSCC) parameters. Twenty-four AC and 48 LLSCC cases (24 with regional nodal metastasis and 24 without regional nodal metastasis) were selected. The scores of immunopositive cells for HLA-DR in the epithelial component of the lesions were assessed and the results were analyzed statistically using the nonparametric Mann-Whitney test. Epithelial expression of HLA-DR was observed in only five (20.8%) cases of AC (two low-grade and three high-grade lesions), with a very low median score of immunopositivity. By contrast, expression of HLA-DR was found in most LLSCC (97.9%), with a relatively high median score of positive cells. The score of HLA-DR-positive cells tended to be higher in tumors with regional lymph node metastasis, tumors in advanced clinical stages, and low-grade tumors, but the difference was not statistically significant (p > 0.05). In addition, there was a tendency towards higher expression of HLA-DR in highly/moderately keratinized tumors, and tumors with little/moderate nuclear pleomorphism (p > 0.05). The results suggest a potential role of HLA-DR in lip carcinogenesis, particularly in the development and progression of LLSCC. The expression of this protein can be related to the degree of cell differentiation in these tumors.

Methods: A search was carried out in the MEDLINE, Google academic and LILACS databases using the following criteria: full articles published, from 2000 to 2016, in English, Portuguese and Spanish, case report and classical articles about the topic, using the following descriptors: jaws, mandible, maxilla, metastasis, incidence and their mesh terms. Results: 35 articles that fulfilled all the criteria were included. There were 452 patients with metastases, of which 53.1% were men. Patient's ages ranged from 4 months to 90 years. The mandible was affected in 55.7% of the cases, and the main primary sites were the breast and lung with 90 and 87 cases each, respectively. In 39% of the sample, the primary tumors were unknown. Adenocarcinoma was the main histopathological pattern found in 30.3% of the sample. Conclusion: Metastatic tumors of the jaws are related to a challenging and late diagnosis with gloomy prognosis of short survival. They most commonly affect the posterior mandibular region between the fifth and eighth decades of life, in both sexes. The dentist practitioner has a great role in the early diagnosis of these lesions. (AU)

Intraoral findings in newborns: prevalence and associated factors

Aim: To investigate the prevalence of intraoral characteristics and associated factors with neonatal and parent variables in a group of Brazilian newborns. Methods: This cross-sectional study with a descriptive and inferential approach, whose data was obtained through clinical examination, interview and the collection of medical record information. The sample was selected from babies up to three days old, of both sexes, and born between January and December 2013 in the Ana Bezerra University Hospital, in the city of Santa Cruz-RN, Brazil. The exposure variables included neonatal (sex, weight, gestational age, type of delivery and Apgar score) and parent (presence of systemic disease(s), drug use and consanguinity between the parents) variables. Descriptive analysis and Poisson regression were performed to estimate the ratio of gross and adjusted prevalence of intraoral findings (Epstein pearls, Bohn's nodule, dental lamina cyst and ankyloglossia) with the neonatal and parent variables (p<0.05). Results: Of a total of 168 examined newborns, 56.5% (n=95) were male. The most prevalent intraoral feature was the fibrous cord of Magitot, 62.5% (n=105), and the most frequent alteration was Epstein pearls, 44.6% (n=75). Female gender was a factor for Bohn's nodule (OR=0.90; 95%CI:0.82-0.99), and no tobacco use by the father was a protective factor for Epstein pearls (OR=0.73;95%CI:0.55-0.97). Additionally, lower mother's age, between 20-34 years of age (OR=1.58;95%CI:1.07-2.35) and under 19 years of age (OR=1.61; 95%CI:1.03-2.52) increases the chance of having Epstein pearls. Conclusion: There was a high prevalence of alterations in the newborns' oral cavities and there were associations between neonatal and parent variables

Perception of dental care among children

Children that arrive at dental offices with fear and anxiety usually tend to resist conditioning mechanisms. The aim this study was to evaluate children's perception about dental treatment and to identify factors that influence this perception. Material and Methods: A random sample of 100 children of both genders aged 3 to 12, who were treated at the Department of Dentistry of a University (group I) and at a Children's Hospital (group II), was selected. A structured questionnaire about the child's perception about dental care was applied and the children were asked to draw a picture of this topic. Most of children expressed a positive perception in the questionnaire and in the drawings (93.8%). This positive perception was more pronounced in group I (94%) and in children aged 3 to 5 years (100%), particularly in girls (78%). The main cause of fear was the use of needles (42.4%). Many children (24.2%) reported to prefer the noninvasive procedures. A positive perception of dental treatment was observed in the majority of the sample. Therefore, dental pediatricians must be aware of the perception of children for better conditioning (Au)

Primary adenocarcinoma of the colon with metastases to the mandible and liver: a case report / Adenocarcinoma primario de colon con metástasis en mandíbula e hígado: reporte de un caso

Metastatic lesions to the mandible may be originated from primary tumors elsewhere in the body. However, metastatic colonic carcinomas to this bone have been described infrequently. We report the case of a 71-year-old man with an adenocarcinoma in the sigmoid colon with liver metastasis. The patient underwent chemotherapy with indication of sigmoidectomy and retroperitoneal lymphadenectomy. One year and four months after the first metastatic diagnosis, the patient presented a tumor mass in the body and branch of the right mandible. Histopathological and immunohistochemical analysis with monoclonal antibodies specific for CEA, CK20, CDX-2, and vilin were compatible with the diagnosis of moderately differentiated metastatic adenocarcinoma with colonic origin. However, due to the wide spread of the disease, the patient died four months later. Tumor markers have been applied in clinical practice to assist in the diagnosis and to help guide prognosis, staging and treatment of cancer. The management of metastatic lesions remains a controversial issue and the development of new and more specific markers of gastrointestinal differentiation that may promote early diagnosis, are of continuous interest.

Las lesiones metastásicas de la mandíbula pueden surgir de los tumores primarios en cualquier partes del cuerpo. Sin embargo, el carcinoma metastásico de colon de este hueso se han reportado con poca frecuencia. Presentamos el caso de un hombre de 71 años de edad, con un adenocarcinoma de colon sigmoide con metástasis en el hígado. El paciente fue sometido a quimioterapia con indicación de sigmoidectomía y linfadenectomía retroperitoneal. Un año y cuatro meses después de la emisión del primer diagnóstico de la metástasis, el paciente presentaba una masa tumoral en el cuerpo y rama de la mandíbula derecha. El análisis histopatológico e inmunohistoquímico con anticuerpos monoclonales específicos para CEA, CK20, CDX-2, y vilin fueron compatibles con el diagnóstico de adenocarcinoma moderadamente diferenciado metastásico originario en el colon. Sin embargo, debido a la amplia propagación de la enfermedad, el paciente murió cuatro meses más tarde. Los marcadores tumorales se han aplicado en la práctica clínica para ayudar en el diagnóstico y ayudar a orientar el pronóstico, la estadificación y tratamiento del cáncer. Gestión de las lesiones metastásicas sigue siendo un tema controvertido, y el desarrollo de marcadores nuevos y específicos que promueven la diferenciación del diagnóstico precoz gastrointestinal, son de interés continuo.

Recurrent Oral Manifestations of Paracoccidioidomycosis without Pulmonary Involvement: Case Report and Review of Literature / Manifestación Oral Recurrente de Paracoccidioidomcosis sin Compromiso Pulmonar: Reporte de Caso y Revisión de la Literatura

This article describes a case of recurrence of chronic paracoccidioidomycosis (PCM) 11 years following the initial diagnosis. The patient was a 51-year-old white Brazilian female, which had been previously diagnosed with PCM. The physical examination revealed the presence of a single crusted lesion in the upper lip and an elevated lesion with fibrous scar appearance on right buccal mucosa. Although the diagnosis of PCM, the absence of pulmonary involvement led to the biopsy of the lesion localized on the buccal mucosa and the histopathological analysis in H&E and PAS stains revealed no morphological changes suggestive of any lesion. However, the exfoliative cytology stained with Grocott-Gomori showed the presence of Paracoccidioides brasiliensis and the infection caused by this fungus was proven. Of this way, we emphasize the importance of stomatologic evaluation to the diagnosis of diseases that usually manifestssystemically. So, the correct diagnosis of oral manifestations of PCM, is essential to ensure early and safe intervention.

En este artículo se describe un caso de paracoccidioidomicosis crónica (PCM) recurrente 11 años después del diagnóstico inicial. La paciente una mujer blanca de Brasil de 51 años de edad, que había sido diagnosticada previamente con PCM. El examen físico reveló la presencia de una lesión única en el labio superior y una lesión elevada con apariencia de cicatriz fibrosa en la mucosa bucal derecha. No obstante el diagnóstico de PCM, la ausencia de compromiso pulmonar llevó a la biopsia de la lesión localizada en la mucosa bucal y el análisis histopatológico no demostró cambios morfológicos indicativos de cualquier lesión. Sin embargo, la citología exfoliativa teñida con Grocott-Gomori mostró la presencia de Paracoccidioides brasiliensis y la infección causada por este hongo fue probado. De esta manera, hacemos hincapié en la importancia de la evaluación odontológica para el diagnóstico de enfermedades que se manifiestan generalmente por vía sistémica. Por lo tanto, el diagnóstico correcto de las manifestaciones orales de PCM es esencial para asegurar la intervención temprana y segura.

Influence of dialysis duration and parathyroid hormone on the clinical and radiographic oral conditions of pre-transplant patients with chronic kidney disease

Aim: To evaluate the oral conditions of patients with chronic kidney disease undergoing dialysisand to determine the influence of dialysis duration and bone metabolism on the prevalence andseverity of the alterations found. Methods: The simplified oral hygiene index (OHI-S), prevalenceof dental caries (decayed, missing filled teeth index, DMFT), and the periodontal screening andrecording (PSR) index were evaluated in 154 patients. Parathyroid hormone (PTH), calcium,phosphorus and urea measurements, as well as panoramic radiographs, were obtained from allpatients. To evaluate the effect of duration of dialysis treatment on oral health, the patients weredivided into two groups: (1) <5 years and (2) > 5 years. Regarding blood levels of PTH, patientswere divided into three groups: (1) 0-149 pg/mL, (2) 150-584 pg/mL, and (3) >585 pg/mL. TheOHI-S identified the accumulation of biofilm and calculus around the teeth. Results: Gingivalinflammation was found in 100% of dentate patients, with 2 being the predominant PSR score(72.3%). The DMFT index was high (17.52). Dental calculus was the most common radiographicfinding (70.8%). No significant correlation was observed between dialysis duration, biochemicalalterations, and oral health. Conclusions: Most patients undergoing dialysis presented precariousoral hygiene, periodontal inflammation, and bone alterations. However, these manifestationswere not influenced by the duration of dialysis or bone metabolism.

Immunohistochemical expression of protein 53, murine double minute 2, B-cell lymphoma 2, and proliferating cell nuclear antigen in odontogenic cysts and keratocystic odontogenic tumor.

Introduction: Even though odontogenic cysts share a similar histogenesis, they show different growth and differentiation profile due to differences in the proliferative cellular activity. Aims: We perform an immunohistochemical assessment of protein 53 (p53), proliferating cell nuclear antigen (PCNA), B-cell lymphoma 2 (bcl-2), and murine double minute 2 (MDM2) expression in odontogenic cysts and keratocystic odontogenic tumor analyzing their correlation with the biological behavior of these lesions. Materials and Methods: By the streptavidin-biotin-peroxidase method with antibodies against p53, PCNA, bcl-2, and MDM2 proteins, 11 radicular cysts, 11 dentigerous cysts, and 11 keratocystic odontogenic tumor were analyzed. The non-parametric Mann-Whitney U-test and Kruskall-Wallis test (P ≤ 0.05) were used to analyze the data. Results: Immunopositivity for PCNA was observed in all cases appraised, predominantly in the suprabasal layer of keratocystic odontogenic tumor epithelial lining (SD ± 19.44), but no significant differences were found among the groups of lesions. Bcl-2 immunoexpression was observed especially in the basal layer of keratocystic odontogenic tumor. PCNA LI was significantly higher than bcl-2 LI in keratocystic odontogenic tumor. MDM2 and p53 immunoexpression were not detected in the lesions studied. Among the evaluated lesions, the keratocystic odontogenic tumor showed different immunoexpression of the proliferation and apoptosis markers. Conclusion: The results of this study suggest that the keratocystic odontogenic tumor presents distinct biological behavior of the odontogenic cysts, as for the processes of proliferation, apoptosis, and differentiation, reinforcing the information in favor of the neoplastic nature of this lesion.

Complicaciones estomatológicas en pacientes VIH positivos: correlaciones clínico demográficas y de laboratorio / Dental complications in HIV positive patients: clinical correlations demographic and laboratory

Las complicaciones estomatológicas (CE) en pacientes VIH+ muchas veces constituyen los primeros signos clínicos de la enfermedad, pudiendo funcionar como señalizadores del curso y progresión de la infección por el VIH y el SIDA. Este estudio evaluó la prevalencia de lesiones orales en pacientes VIH+ del Hospital de Enfermedades Infectocontagiosas Gizelda Trigueiro, en Natal-RN, Brasil y correlacionarlas con factores socio-demográficos como el sexo, edad, forma de contagio y status inmunológico. De acuerdo con los criterios de la EC-CLEARINGHOUSE/WHO, a través de examen clínico oral y conteo de células T CD4+ fueron evaluados 121 pacientes VIH+. Las lesiones más frecuentes fueron candidiasis (45.2%), leucoplasia vellosa (16.1%), eritema gingival linear (16.1%), herpes labial (12.9%), periodontitis necrosante (6.5%) y gingivitis necrosante (3.2%), ocurriendo con mayor frecuencia en hombres entre las edades de 30 a 44 años, que adquirieron el VIH a través de contacto sexual. Basado en los resultados de este estudio concluyese que hubo una prevalencia del perfil de complicaciones estomatológicas comúnmente relatado en la literatura. Las lesiones estuvieron asociadas a la reducción del número de células TCD4+, representando, por lo tanto marcadores de la progresión de la infección por el virus y/o de falla de la HAART, siendo así, un exhaustivo examen oral es importante en la evaluación clínica y acompañamiento de pacientes con VIH.

The stomatologic complications due to VIH infection are, a lot of times, the first clinical signs of the disease. These injuries may also function as beepers and sentries of the curse and progression of the VIH infection and SIDA. The objective of this work was to evaluate the prevalence of the oral injuries in VIH positive patients from the Hospital of Infected contagious Gizelda Trigueiro in Natal-RN, Brazil, and correlate them with demographic factors such as gender, age, form of VIH infection and immune status (T CD4+ cells). According to the criteria of EC-CLEARINGHOUSE/WHO, through clinical oral examination and T CD4+ cell count 121 patients were evaluated. The oral candidiasis was the most common lesion (45.2%), followed by oral hairy leukoplakia (16.1%), linear gingival erythema (16.1%), lips herpes (12.9%), necrotizing periodontitis (6.5%) and necrotizing gingivitis (3.2%), occurring predominantly in men between the ages 30 to 44 years, who acquired VIH infection through sexual contact. Based on the results of this study, concluded that there was a prevalence of the stomatologic complications profile that is commonly reported in the literature. These changes were associated with a decrease in the number of CD4+ T cells, representing markers of the infection progression and / or failure of HAART, so a thorough oral examination is important in clinical evaluation and follow up of patients with VIH.
