RESUMO
BACKGROUND: People with chronic obstructive pulmonary disease (COPD) in Nepal are not receiving adequate support to self-manage their chronic conditions, and primary health care can play a key role in the effective management of these. In this study, we aimed to develop a model of care, using a co-design approach, for delivering evidence-based biomedical and psycho-social care to support self-management for people with multi-morbid COPD in rural Nepal. METHODS: A co-design approach, guided by the five stages of the design thinking model, was used for this study. Layering on "empathize" and "define" phases, we ideated a model of care that was further refined in a "prototype" stage, which included a series of consultative meetings and a 1-day co-design workshop with stakeholders. This co-design process involved a wide range of stakeholders from Nepal, including people with COPD and their families, community representatives, local government representatives, primary care practitioners, community health workers, policymakers, state-level government representatives and academics. RESULTS: Through our co-design approach, a model of integrated care for delivering evidence-based biomedical and psycho-social care to support self-management for people with multi-morbid COPD was designed. The integrated model of care included: screening of the community members aged > 40 years or exhibiting symptoms for COPD and management of symptomatic patients within primary health care, establishing referral pathways for severe cases to and from secondary/tertiary-level health care and establishing a community-based support system. It involved specific roles for community health workers, patients and their caregivers and community representatives. It was built on existing services and programmes linking primary health care centres and tertiary-level health facilities. CONCLUSION: The co-design approach is different from the currently dominant approach of rolling out models of care, which were designed elsewhere with minimal community engagement. In our study, the co-design approach was found to be effective in engaging various stakeholders and in developing a model of care for rural Nepal. This grassroots approach is more likely to be acceptable, effective and sustainable in rural Nepal. Further research is required to test the effectiveness of an integrated model of care in delivering self-management support for people with multi-morbid COPD in rural Nepal.

BACKGROUND: Chronic Obstructive Pulmonary Disease (COPD) is a progressive and debilitating condition that affects individuals' quality of life. COPD self-management and supports provided by carers is key to the quality of life people living with COPD. Health literacy (HL) and Patient Activation (PA) are main drivers of self-management practices (SMPs). However, their contribution remains to be fully explored. This study aimed to examine the level of self-management practices, and the relationship with socio-demographic factors, HL and PA among multi-morbid COPD patients from rural Nepal. METHODS: This is a cross-sectional study conducted between July 2018 and January 2019. Patients completed a survey, including Self-management Practices questionnaire (SMPQ), five domains of the Health Literacy Questionnaire (HLQ), and Patient Activation Measure (PAM). The relationship between HL, PAM, and SMPs was examined using univariate statistics. Multivariable analysis was conducted to identify the factors associated with SMPs. RESULTS: A total of 238 patients responded to the study. The mean score of SMPQ was 45.31(SD = 9.00). The HLQ and PAM scores were positively correlated with the total score of SMPQ. Low level of SMPs were found to be positively associated with being uneducated (ß = - 0.43, p = .001), having a low family income (ß = - 5.22, p = .002), and, negatively associated with the presence of more than one co-morbidity (ß = 3.58, p = 0.007) after controlling for other socio-demographic variables in the multivariable analysis. CONCLUSION: The overall SMPs among this sample of Nepalese with COPD were low. Our findings highlight the need to implement a self-management intervention program involving patient activation and health literacy-focused activities for COPD, creating a support system for patients from low-income families and low education.

Introduction: Existing tests for the diagnosis of pleural tuberculosis (TB) have major limitations in terms of accuracy, time to diagnosis and drug resistance testing. A test which can diagnose pleural TB and detect resistance, like Xpert MTB/Rif, would be optimal for rapid diagnosis and treatment. Methods: A prospective observational study was done in a tertiary care hospital in Eastern Nepal. Fifty-one patients with clinic-radiologic suspicion of pleural TB were included. The results of pleural fluid Xpert MTB/Rif were compared with two Composite Reference Standards. Composite Reference Standard-1 consisted of positive pleural fluid smear, positive culture, positive histology of pleural biopsy, and positive sputum results. Composite Reference Standard-2 included those with Composite Reference Standard-1 and those with high ADA values (>40 U/l) with response to anti-tubercular treatment at 8 weeks of follow-up. Results: Thirty-six patients were diagnosed as Pleural TB. Nine fulfilled Composite Reference Standard-1. Pleural fluid Xpert MTB/Rif was positive in five cases with Composite Reference Standard-1 and nine cases with Composite Reference Standard-2. The sensitivity, specificity, positive predictive value and negative predictive value with reference to Composite Reference Standard-1 were 55.56%, 88.10%, 50%, and 90.24%, respectively. Using Composite Reference Standard-2 as reference, sensitivity, specificity, positive predictive value and negative predictive value were 25%, 93.33%, 90%, and 34.15%, respectively. Two cases were diagnosed Xpert Rif resistant on pleural fluid. Conclusion: Due to low sensitivity, the Xpert MTB/Rif test cannot be recommended as initial test of diagnosis in a high prevalence setting. At the same time its clinical utility lies in testing of patients suspected to have drug-resistant pleural tuberculosis.
RESUMO
Background: Telemedicine, a part of Medical Informatics used to consult patients from remote places either via videoconferencing or transferring data and resources via the Store and Forward method, makes the quality of healthcare in low-and middle-income countries more efficient, cost-effective, and accessible. The objectives of this study were to determine its effects on the health of refugees and its efficacy in terms of referrals and cost reduction for healthcare service providers among Bhutanese refugees in eastern Nepal. Methods: This was a cross-sectional study done retrospectively from the records of patient data of Bhutanese refugees from AMDA, Damak, and prospectively by asking the questionnaire to the healthcare providers of Beldangi PHC of AMDA, Damak. Results: The total percentage of patients that were seen via teleconsultation in the primary center was 58% male and 42% females, whereas from the secondary center, males were 43% and females constituted 57%. The referral rate from those primary centers and secondary centers were decreased to 31% and 39%, respectively, from 72% and 61% from previous records. The budget expenditure was also decreased to 13.65% from 29.41%. Conclusions: Telemedicine is beneficial in those types of refugee camps where there are chains of referring patients from primary health centers to tertiary care centers via secondary healthcare centers. As it not only decreased the referral rate but also save the budget expenditure, which are needed when referring those patients to other centers.
RESUMO
Hepatitis A virus infection is the commonest form of hepatitis in pediatric age group and common health problem in developing countries due to poor sanitation. The clinical spectrum of hepatitis A virus infection ranges from asymptomatic infection to fulminant hepatitis and the symptoms are primarily hepatobiliary or constitutional. Here, we present a case of 16 years old male who presented with complains of fever, vomiting, anorexia, right sided abdominal pain, shortness of breath and cough. On clinical examination, patient has hepatomegaly and decreased breath sounds on right sided mammary, infra- mammary and infra scapular region. Blood investigations showed aminotransferases while pleural effusion and ascites with thickened gall bladder were found in chest x-ray and abdominal ultrasonography respectively. In absence of others causes, pleural effusion can be a rare complication of hepatitis A. Thus, this complication should be kept in mind in endemic countries in clinically matching scenarios. Keywords: Acalculous cholecystitis; ascites; hepatitis A; pleural effusion.

Small cell lung cancer mostly arises centrally in the large bronchi. The literature search revealed very limited cases of small cell lung cancer arising at the upper part of the pulmonary sulcus near the thoracic inlet as superior sulcus tumor and also manifesting with typical Pancoast syndrome. We report a case of a 71 years old male patient, presenting with features of Pancoast syndrome including Horner's syndrome with completed three cycles of chemotherapy resulting in partial response which concludes that small cell lung carcinoma has to be considered despite the clinical findings like pancoast syndrome.

INTRODUCTION: Pleurodesis is a procedure to achieve symphysis between the two layers of pleura aimed at preventing the accumulation of either air or fluid in the pleural space. In Nepal, intrapleural instillation of the chemical sclerosing agent is more commonly done as thoracoscopy facility is not easily available. However, iodopovidone is rarely used for this purpose in Nepal. The study aims to find the prevalence of success using iodopovidone as the chemical sclerosing agent. METHODS: The study included cases undergoing pleurodesis over a two-year period. The clinicodemographic data, diagnosis, treatment effect and treatment response were analyzed. The treatment response was graded as Treatment Success (Complete Response or Partial Response) and Treatment Failure. RESULTS: Pleurodesis was done in a total of 54 cases. Of those, 39 cases were Secondary Spontaneous Pneumothorax, 11 were Malignant Pleural Effusion, 3 were Primary Spontaneous Pneumothorax, and 1 was a case of Hepatic Hydrothorax. Among Secondary Spontaneous Pneumothorax, Pleurodesis was successful in 37 (95%) out of 39 cases, with 35 (90%) having a Complete Response and 2 (5%) having a Partial Response while 2 (5%) had Treatment failure. Among Malignant Pleural Effusion, treatment success was achieved in 6 (55%) out of 11, whereas 5 (45%) failed the treatment. The commonest complication was burning sensation, and the commonest pain scale was "distressing." CONCLUSIONS: This study highlights the safety and ease of use of iodopovidone as an agent for chemical pleurodesis. It confirms the high rate of success of pleurodesis in cases of pneumothorax as found in other studies. In contrast, the success rate is understandably lower in cases of Malignant Pleural effusion.

OBJECTIVE: To understand the feasibility and acceptability of a co-design approach to developing an integrated model of healthcare for people with multi-morbid chronic obstructive pulmonary disease (COPD) in rural Nepal. SETTINGS: A rural setting of Nepal. PARTICIPANTS: Data collection included five video recordings, five key informant interviews and observation notes from a final co-design workshop that involved a total of 68 stakeholders: persons with COPD and their family members; healthcare providers, including respiratory physicians; local community leaders; representatives from local, provincial and federal government; academics; and representatives from non-government organisations. PRIMARY AND SECONDARY OUTCOME MEASURES: Feasibility and acceptability of using a co-design approach to develop an integrated model of care for people with multi-morbid COPD in rural Nepal. RESULTS: Our qualitative evaluation of the Hasso Plattner's co-design process found that all stakeholders (including people with COPD/community members, primary care practitioners and local government/senior health officials) were actively engaged in and significantly contributed to the process of co-design. Four main themes were identified which determined the feasibility and acceptability of the resulting integrated model of care: engagement of stakeholders, factors contributing to the co-design, consequences of the co-design process, and challenges and opportunities learnt by the researchers and participants in the co-design process. Based on the relationship between the four main themes emerging from this research, we developed an evaluation framework to guide the co-design of a health service innovation. CONCLUSION: Our study demonstrated the feasibility and acceptability of the Hasso Plattner's co-design process. Our findings suggest that this co-design approach can be useful and acceptable to local communities and government agencies. It enabled the meaningful contribution of a diverse group of stakeholders in the design and delivery of health services in low-income and middle-income countries.

Non-bacterial thrombotic endocarditis is a rare condition characterized by noninfectious vegetation on cardiac valves which are often associated with malignancy. It often presents with features of embolism rather than cardiac failure. These are usually seen in autoimmune conditions, disseminated intravascular coagulation, malignancy of gut and lung but has also been reported in other malignancies as well. This entity is rare but one must have a clinical suspicion of the disease especially in a patient suffering from malignancy presenting with the embolic phenomenon. In this report, we are presenting a case of non-bacterial thrombotic endocarditis in an inpatient with pleural mesothelioma, a rare malignant neoplasm arising from pleura in a 35 years old mason, and a rare association as well.

Background: Telemedicine is a process which involve medical experts to exchange valid information for diagnosis, clinical management, treatment and counseling for both healthcare workers and patients remotely in rural setting from urban healthcare center. Providing quality healthcare services in Nepal is challenging due to many reasons such as difficult geographic terrain, limited availability of funding and many other issues. Methods: The study design was a cross sectional and will adopt an interpretative case study approach which supports the researcher to develop a deep insight in to study phenomenon and outcomes. Study was conducted at in two rural-telemedicine programme implementation sites, namely Patle, Fikkal Bazaar and one central consultation site BPKIHS Dharan. Result: A total of 315 patients were undergone teleconsultation process during the study period. The total patients consulted after teleconsultation program in each of center were 1386 (Phikal) and 508 (Patle). Among them 205 (Phikal) and 110 (Patle) were called on the teleconsultation day. Among the patients who were seen via teleconsultation, 36 (2.6 %) from Phikal and 22 (4.3%) from Patle were referred to BPKIHS. The total number of referred patient from those center to other center were 327(Phikal) and 208 (Patle) among those referred 205 (Phikal) and 110 (Patle) came during teleconsultation Process. Conclusion: Telemedicine can be used as a critical component in the solution of the healthcare crisis. Telemedicine will be the best as a substitute to improve the access to healthcare, to provide the healthcare cost-effectively. The current paradigm of care can be taken by telemedicine due to which improved health outcomes can be achieved in cost effective Ways.

It is unusual to be able to visualize an entire cavity with such clarity.
RESUMO
Lung is the second most common site of hydatid disease, after liver. Pleural involvement of hydatid disease can occur, and usually follows the rupture of a pulmonary or hepatic hydatid cyst into the pleural space. When a patient presents with tension pneumothorax, zoonotic infections, especially hydatid disease of the lung, also has to be considered especially in areas with high burden of the disease. We report a 31 years male patient presenting with tension pneumothorax due to rupture of hydatid cyst of lung.

OBJECTIVE: To understand the facilitators and barriers to the self-management of chronic obstructive pulmonary disease (COPD) in rural Nepal. SETTINGS: Community and primary care centres in rural Nepal. PARTICIPANTS: A total of 14 participants (10 people with COPD and 4 health care providers) were interviewed. PRIMARY AND SECONDARY OUTCOME MEASURES: People with COPD and healthcare provider's experience of COPD self-management in rural Nepal. RESULTS: Facilitators and barriers affecting COPD self-management in Nepal operated at the patient-family, community and service provider levels. People with COPD were found to have a limited understanding of COPD and medications. Some participants reported receiving inadequate family support and described poor emotional health. At the community level, widespread use of complementary and alternative treatment was found to be driven by social networks and was used instead of western medicine. There were limited quality controls in place to monitor the safe use of alternative treatment. While a number of service level factors were identified by all participants, the pertinent concerns were the levels of trust and respect between doctors and their patients. Service level factors included patients' demands for doctor time and attention, limited confidence of people with COPD in communicating confidently and openly with their doctor, limited skills and expertise of the doctors in promoting behavioural change, frustration with doctors prescribing too many medicines and the length of time to diagnose the disease. These service level factors were underpinned by resource constraints operating in rural areas. These included inadequate infrastructure and resources, limited skills of primary level providers and lack of educational materials for COPD. CONCLUSIONS: The study findings suggest the need for a more integrated model of care with multiple strategies targeting all three levels in order to improve the self-management practices among people with COPD.

BACKGROUND: Health literacy (HL) and patient activation (PA) are necessary foundations to engage patients in self-management intervention. Each concept plays a unique role in improving access to the effective self-management of chronic disease. In this cross-sectional study, we examined the levels and determinants of HL and PA among the multi-morbid COPD patients in Nepal. METHODS: We conducted interviews with a simple random sample of 238 multi-morbid COPD people from July 2018 to January 2019. The questionnaire included sociodemographic profiles, five domains of the Health Literacy Questionnaire (HLQ), 13-item Patient Activation Measure (PAM) and patient's illness perception by Brief Illness Perception Questionnaire (BIPQ). Multivariable logistic regression was used to examine the associations. RESULTS: Most people with COPD had low health levels across each of the five domains of the HLQ. The proportion of people with low literacy level across each of the domains was: (i) feeling understood and supported by healthcare providers (79.0%), (ii) having sufficient information to manage my own health (76.5%), (iii) social support for health (77.3%), (iv) ability to find the good health information (75.2%), and (v) understand the health information well enough to know what to do (74.8%), respectively. The majority of patients also reported low levels of patient activation (level 1: 81.5%; level 2: 11.8%), with only 6.7% (level 3: 5%; level 4: 1.7%) reported higher patient activation level. We found significant associations between poor HL levels in the HLQ domains and having no education, being female or from Indigenous and Dalits communities, and having a monthly family income of less than USD176. Having no education and poor illness perception were significantly associated with poor activation level on PAM scale. CONCLUSION: A high proportion of multi-morbid COPD peoples had low levels of HL and were less activated than what would be required to self-manage COPD. These were in turn associated with socioeconomic factors and poor illness perception. The findings from this study are being used to design a COPD self-management program tailored to the low health literate population.

INTRODUCTION: Exposure to dusts and hard physical work is common in developing industrialized countries. Acute and chronic respiratory illnesses are highly been reported from jute and textile industry. This study was undertaken to explore status of respiratory health among the workers of jute and textile industries. METHODS: This descriptive cross-sectional study enrolled 315 workers from each of textile and jute industry of Eastern Nepal. Almost all the workers were selected from the textile industry whereas those from dust prone areas of jute industry. Workers were interviewed using pre-tested questionnaires. Measurement of height, weight and peak expiratory flow rate was done. RESULTS: Majority were non-smokers in both the industries 230 (73%) in Jute vs. 223 (70.8%) in Textile. Most of the workers had the working experience of less than five years; jute 134 (42.5%) vs. textile 180 (57.1%). Upper respiratory disorder was found in more than 1/5 of workers (68) in jute vs. 1/20 of workers (18) in textile industry. One and two workers suffered from chronic bronchitis in the jute and the textile industry respectively. Chest tightness was reported among 4 (1.3%) in jute vs. 17 (5.4%) in textile workers, cough symptoms among 86 (27.3%) in jute vs. 26 (8.3%) in textile industry. Low practice of personal protective measure was seen in both industries. The mean score of PEFR of workers in jute mill was lower than the workers in textile industry. CONCLUSIONS: Workers with acute respiratory disorders were more in the jute industry while chest tightness was more in the textile industry. Chronic respiratory problems did not appear to be alarming in both the industries. Use of personal protective measures should be promoted among the dust exposed workers.

Solvent abuse, as inhalant specially, in the form of low cost adhesives like dendrite is common in low income countries among children and the teens. This habit is often a stepping stone to harder drugs. The neurological and neuropsychological effects of solvent abuse are well explored. But the respiratory effects are often overlooked. In this report, we present a case of a 19 year old gentleman, with regular history of sniffing of commercial "glue" compounds. This patient presented with right sided chest pain and chest x-ray showed a right sided pneumothorax. The pulmonary barotrauma, possibly due to increased intra-alveolar pressure, during the sniffing process can lead to alveolar rupture and in turn, pneumothorax. In the absence of other risk factors for Pneumothorax, the link between inhalant abuse and respiratory complications has to be explored in patients with history of such abuse. Keywords: inhalant abuse; pneumothorax; solvent.

Adenosine deaminase activity (ADA) was assayed in pleural fluid and serum of 42 subjects with pleural effusion. Twenty-nine of them had TB pleural effusion and the remaining 13 had pleural effusion due to non-TB respiratory diseases. Serum adenosine deaminase activity were also measured in 32 pulmonary tuberculosis patients without pleural effusion and equal numbers of healthy controls without systemic diseases for comparative analysis. The patients attending the medicine out-patient department (MOPD) of the B. P. Koirala Institute of Health Sciences, Dharan, Nepal were taken as study subjects. Serum and pleural fluid ADA activities were assayed spectrophotometrically by the method of Guisti and Gallanti. The mean serum ADA activity was significantly increased in patients with tubercular pleural effusion (34.53 +/- 10.27 IU/l) compared to pulmonary tuberculosis patients without pleural effusion (26.54 +/- 4.76 IU/l), (p = 0.004), those with non-TB respiratory disease (16.71 +/- 5.16 IU/l), (p = 0.0001) and healthy controls (15.53 +/- 4.4 IU/l) (p = 0.0001). The mean ADA in the pleural fluid of tubercular pleural effusion patients (90.29 +/- 54.80 IU/l) was significantly higher compared to those with non-TB respiratory disease (24.43 +/- 9.28 IU/l) (p = 0.0001). Using the lowest cutoff value for enzyme activity in the serum of patients with TB pleural effusion (25 IU/l), a test sensitivity of 72.41% and specificity of 81.53% were obtained. Using the lowest cutoff value for enzyme activity in pleural fluid of patients with TB pleural effusion (45 IU/l) the sensitivity and specificity for diagnosis were 76.10% and 100%, respectively. Therefore, the measurement of ADA in tubercular pleural effusion has a utility in the diagnosis of tuberculosis when other clinical and laboratory tests are negative.

This case-control study followed by a longitudinal cohort study was undertaken to evaluate the level of lipid peroxidation product malondialdehyde (MDA) and nitrite as an indirect measurement of nitric oxide vis-à-vis the levels of antioxidants vitamin C and vitamin E in pulmonary tuberculosis. Fifty-six sputum smear-positive cases of pulmonary tuberculosis based on Ziehl-Neelsen (ZN) staining and 50 healthy controls without any systemic disease were included in this study. Thirty-five cases were longitudinally followed up with standard antituberculosis chemotherapy (ATT) for two months. Serum levels of malondiadehyde (MDA), nitrite, and plasma levels of vitamins C and E were measured. The mean serum MDA level was significantly higher (8.1 +/- 1.61 nmoles/ml) in PTB patients before commencement of ATT as compared to healthy controls (3.45 +/- 1.7 nmoles/ml) (p=0.0001) and decreased significantly after 2 months of ATT (3.84 +/- 1.28 nmoles/ml) (p=0.0001). The mean serum nitrite level (47.19 +/- 18.44 micromol/l) was significantly elevated before ATT compared to healthy controls (32.89 +/- 11.94 micromoles/l) and decreased significantly after 2 months of ATT (27.71 +/- 11.97 micromoles/l) (p=0.0001). The mean plasma levels of vitamins C (0.88 +/- 0.33 mg/dl) and E (0.79 +/- 0.24 mg/dl) in PTB patients before commencement of ATT were lower than healthy controls (1.42 +/- 0.38 mg/dl) and (1.35 +/- 0.35 mg/dl), respectively (p=0.001). There was a significant increase in vitamin C levels after 2 months of ATT (1.19 +/- 0.40 mg/dl) compared to before ATT (0.83 +/- 0.31 mg/dl) (p=0.0001), but no significant change in mean plasma vitamin E level before and after 2 months on ATT was found. Elevated malondialdehyde and nitrite levels with concomitant depressed vitamin C and E levels are indicative of lipid peroxidation and oxidative stress. The decrease in levels of malondialdehyde and nitrite with subsequent increase in vitamin C levels after two months of follow-up indicate a good response to treatment with standard ATT. Hence, the extent of oxidative stress in PTB can be evaluated by analyzing lipid peroxidation product, antioxidant and nitric oxide levels.
