Symptoms Less Status of a Case of Bilateral Nasal Polyposis: A Case Report

Nasal Polyposis (NP) is not simply mucosa oedema, but rather grape shaped, smooth, soft, freely mobile mucosal swellings that are often visible on anterior rhinoscopy. Polyps arise from the lateral wall of nose. NP may be present without clinically significant sinus disease and vice versa. In Ayurveda, polyposis can be understood with Nasa Arsha. Modern management includes antibiotic, systemic and topical corticosteroids, decongestants and surgery. And lot of chances for recurrence after surgery especially in Ethmoidal polyps. In Ayurveda, various treatment modalities have been proposed for the treatment of Arsha as Shastra karma (operative procedure), Kshara karma (applying some alkaline drugs), Agni karma (cauterization) and Bhaishaja (conservative/medical treatment). The reported case revealed that B/L ethmoidal polyps are high recurrence rate after surgery and can be managed with Ayurvedic medicine to give sustained relief from symptoms.

Work Environment and Workload of Staff Nurses in Level 2 Hospitals at Cavite, Philippines

@#One of the greatest healthcare challenges for today's generation is the improvement of the nursing work environment. Despite the challenges brought by the unhealthy working environment and high workload demand, Filipino nurses stood up high in maintaining professionalism towards their work. The goal of this study is to determine the relationship between the work environment and the workload of staff nurses in level 2 hospitals in Cavite, Philippines. Quantitative non-experimental descriptive correlational design was used, and the standardized questionnaires namely: Practice Environment Scale of the Nursing Work Index (PES-NWI) and NASA Task Load Index (NASA-TLX) were used to gather data from 70 respondents. Results showed that majority were female, belonging to Millennial age (23-38 years old), had baccalaureate degree in Nursing, with a gross monthly salary of Php 15,000.00- 19,999.00, being in the institution for more than 6 months to 5 years, and have an average nurse to patient ratio of 11.30. Their level of work environment was favorable in all subscales with a composite score of 3.13 (SD= 0.570). Their perceived workload was high, with a mean score of 71.24 (SD= 12.78). Likewise, nurse to patient ratio had a significant relationship with nurse manager ability, leadership, and support of nurses (X2= 94.26, p= <.001) and staffing and resource adequacy (X2= 75.06, p= 0.002). Moreover, significant relationships among the variables of age and physical demand (p= .004), length of institutional experience and physical demand (p <0.001), educational attainment and performance (p= .018), educational attainment and effort (p= .005), and length of institutional experience and effort (p= .001). Last, there is no statistically significant correlation between the overall work environment and the overall workload of nurses (r= -.084, p= .491). These findings underscore the importance of measures aimed at enhancing the work environment and workload of staff nurses to prevent further challenges among them.

The Measurement Of Nurses’ Mental Workload Using Nasa-Tlx Method (A Case Study)

@#Nurse is a profession that has a quite high workload. It can be seen from how often they should encounter situations which compel them to undergo precisely right decision in saving patients’ lives. Various environmental conditions increase the frustration rate of the nurses, such as noise of the crowds and medical equipment, as well as smell of medicines and wounds at once. Moreover, demands from the patients’ family make it even tougher for them. Therefore, this study aims to measure the mental workload of the nurses at Intensive Care Unit (ICU) and emergency unit (IGD) in the Hospital ZA based on their years of service. The study was conducted using the method of NASA-TLX (National Aeronautics and Space Administration – Task Load Index). It measured the workload in six dimensions: Mental Demand (MD), Physical Demand (PD), Temporal Demand (TD), Own Performance (P), Effort (EF), and Frustration Rate (FR). The results of the study show that the average value of the nurses’ workload at ICU and IGD is in the category very high (respectively 80 and 83) for the nurses with 0-3 years of service, and the most contributing factor for both the primary groups is the effort (EF).

Frequency and variability of dental morphology in deciduous and permanent dentition of a Nasa indigenous group in the municipality of Morales, Cauca, Colombia / Frecuencia y variabilidad de la morfología dental en dentición temporal y permanente de un grupo de indígenas Nasa del municipio de Morales (Cauca, Colombia)

Abstract Objectives: To determine the frequency, variability, sexual dimorphism and bilateral symmetry of fourteen dental crown traits in the deciduous and permanent dentition of 60 dental models (35 women and 25 men) obtained from a native, indigenous group of Nasa school children of the Musse Ukue group in the municipality of Morales, Department of Cauca, Colombia. Methods: This is a quantitative, descriptive, cross-sectional study that characterizes dental morphology by means of the systems for temporary dentition from Dahlberg (winging), and ASUDAS (crowding, reduction of hypocone, metaconule and cusp 6), Hanihara (central and lateral incisors in shovel-shape and cusp 7), Sciulli (double bit, layered fold protostylid, cusp pattern and cusp number) and Grine (Carabelli trait); and in permanent dentition from ASUDAS (Winging, crowding, central and lateral incisors in shovel-shape and double shovel-shape, Carabelli trait, hypocone reduction, metaconule, cusp pattern, cusp number, layered fold protostylid, cusp 6 and cusp 7). Results: The most frequent dental crown features were the shovel-shaped form, grooved and fossa forms of the Carabelli trait, metaconule, cusp pattern Y6, layered fold, protostylid (point P) and cusp 6. Sexual dimorphism was not observed and there was bilateral symmetry in the expression of these features. Conclusions: The sample studied presented a great affinity with ethnic groups belonging to the Mongoloid Dental Complex due to the frequency (expression) and variability (gradation) of the tooth crown traits, upper incisors, the Carabelli trait, the protostylid, cusp 6 and cusp 7. The influence of the Caucasoide Dental Complex associated with ethno-historical processes cannot be ruled out.

Resumen Objetivos: Determinar la frecuencia, la variabilidad, el dimorfismo sexual y la simetría bilateral de 14 Rasgos Morfológicos Dentales Coronales (RMDC) en dentición temporal y permanente de 60 modelos (35 mujeres y 25 hombres) obtenidos de un grupo de indígenas escolares Nasa del cabildo Musse Ukue del municipio de Morales, departamento del Cauca. Métodos: Estudio descriptivo transversal cuantitativo que caracteriza la morfología dental mediante los sistemas en dentición temporal Dahlberg (winging), Asudas (crowding, reducción de hipocono, metacónulo y cúspide 6), Hanihara (incisivos centrales y laterales en pala y cúspide 7), Sciulli (doble pala, protostílido, pliegue acodado, patrón cuspídeo y número de cúspides) y Grine (cúspide de Carabelli); y en dentición permanente Asudas (Winging, crowding, incisivos centrales y laterales en pala, doble pala, cúspide de Carabelli, reducción del hipocono, metacónulo, patrón cuspídeo, número de cúspides, pliegue acodado, protostílido, cúspide 6 y cúspide 7). Resultados: Los RMDC más frecuentes fueron la forma de pala, formas surco y fosa de la cúspide de Carabelli, metacónulo, patrón cuspídeo Y6, pliegue acodado, protostílido (punto P) y cúspide 6. No se observó dimorfismo sexual y hubo simetría bilateral en la expresión de los rasgos. Conclusiones: La muestra estudiada presenta una alta afinidad con grupos étnicos pertenecientes al Complejo Dental Mongoloide debido a la frecuencia (expresión) y variabilidad (gradación) de los RMDC, incisivos en pala, la cúspide Carabelli, el Protostílido, la cúspide 6 y la cúspide 7; sin embargo, no se puede descartar influencia del Complejo Dental Caucasoide asociado con procesos etno-históricos.

O objetivo desta pesquisa foi realizar avaliação das condições ergonômicas de analistas de sistemas, com a finalidade de conhecer os fatores geradores de sobrecargas físicas e cognitivas, suas repercussões sobre os trabalhadores e propor melhorias para a diminuição dessas sobrecargas. Metodologia:Foram utilizados o método SHTM (sistema homem-tarefa-máquina) de avaliação ergonômica; o diagramade Corlett, para a avaliação do desconforto corporal; o questionário de avaliação do mobiliário; e o NASATLX,para a avaliação de carga mental de trabalho. Resultados: Foram encontradas as prevalências de dorna coluna lombar (71%) e na coluna cervical (64%) dos entrevistados. Após a avaliação da carga mental de trabalho, foi observado que a demanda mental foi a mais exigida entre os analistas de sistemas e a média da carga global foi de 13,23. Conclusão: Pode-se concluir que a alta prevalência de dor musculoesquelética pode ser causada pela presença de mobiliário inadequado, pela adoção de posturas incorretas e pela alta exigência mental das atividades desenvolvidas.

OBJECTIVE: The purpose of this research was to conduct assessment of ergonomic conditions of systems analysts in order to understand the factors causing physical and cognitive overload, its implications for workers and propose improvements to reduce these physical and cognitive overload.METHODOLOGY: The SHTM (human-machine-task) method was used for ergonomic evaluation, the Corlett diagram for evaluation of bodily discomfort, questionnaire evaluation of the furniture and the NASA-TLX to assess mental workload. RESULTS: It was found a prevalence of pain in the lumbar spine of 71% and 64% of respondents in the cervical spine. After evaluation of mental workload, it was observed that the mental demand was most required among systems analysts and the average loading rate was of 13.23. CONCLUSION: It can be concluded that the high prevalence of musculoskeletal pain may be caused by the presence of inappropriate furniture, adoption of incorrect postures and high mental demand of the developed activities performed by systems analysts.
