Efficacy and Safety of the Awake Prone Positioning in Patients with COVID-19 Related Respiratory Distress: A Scoping Review.

Prone positioning (PP) is becoming an important treatment modality for the management of COVID-19 related respiratory distress syndrome. The aim of this scoping review was to evaluate effectiveness and safety of awake PP in non-intubated patients with COVID-19 related acute respiratory distress at different care settings. The study was conducted during December 1, 2019 to August 30, 2020 using health science electronic databases and grey literature. A PRISMA flow diagram was used and finally 06 studies with 187 patients were included for review. Male patients were predominating with the mean age of approximately 55 years. Oxygenation was improved in 79.14% patients. One hundred fifty seven (83.95%) patients with COVID-19-related hypoxemic respiratory distress tolerated the procedure. Intubations required 25.41% of the patients or mechanical ventilation and 6(3.2%) patients expired. Number of patients in the reported studies could tolerate more than 3 hours of PP without a major side effect. Awake proning improved oxygenation of the patients suffering from COVID-19 related respiratory hypoxia in different care settings. Early instituted prone positioning may be an effective alternative method of treating COVID-19 related respiratory distress. Patient compliance and small size cohort studies are the limitations of this review. Multicenter controlled studies are warranted before conclusions are made about safety and the settings.

Multidimensional evaluation of changes in limb function following botulinum toxin injection in persons with stroke.

BACKGROUND: There are limited evidence of instrumented measures of gait and balance to determine the functional effects of botulinum toxin injections (BoNT-A) in spasticity after stroke. OBJECTIVE: To evaluate the functional changes in gait and balance following upper limb and lower limb BoNT-A in persons with stroke. METHODS: A pre-post prospective study of 35 stroke patients with upper and/or lower limb spasticity after focal treatment with BoNT-A. Assessments were at baseline (T0), 6-weeks (T1) and 12-weeks (T2), using validated subjective and objective physical activity measures. RESULTS: After BoNT-A injections, significant improvements in most measures of impairments, activity and participation domains were found at T1 (p < 0.05, effect sizes (r) = 0.5-0.9). There was a significant increase in low intensity physical activity (at T1) and sedentary time reductions at both follow-up periods. Instrumented gait/balance measures showed a significant increase in cadence and turn velocity, but no changes in sway measures were found using posturography. Improvements in most outcome measures were maintained at 12-weeks. CONCLUSION: BONT-A improved scores in most clinical measures but only in some of the objective gait/balance and physical activity measures. Further robust studies should utilize a larger sample size to better determine the benefits of BoNT-A for stroke-related spasticity.

Assessment and Comparison of Quality of Life in Patients with Melasma and Vitiligo.

Background Melasma is an acquired hyperpigmentary condition that is characterized by development of irregular brown to black macules occurring predominantly on the face. Vitiligo is an acquired depigmenting skin disease characterized by progressive loss of inherited skin colour, which leads to appearance of white patches. Both the conditions occur more frequently in people with racially pigmented skin resulting in psychological morbidities and impacting the quality of life. Objective To evaluate and compare the quality of life in patients suffering from melasma or vitiligo, which represent two opposite ends of pigmentary disorders using the Dermatology Life Quality Index (DLQI). Method This was a hospital based cross sectional study that was conducted at the Department of Dermatology and Venereology, Tribhuwan University Teaching Hospital from September 2016 to August 2017. The study population included adult patients of either sex with melasma or vitiligo, who consented to participate in the study. Result There were a total of 100 patients each in both melasma and vitiligo groups. While females outnumbered their male counterparts by a ratio of 9:1 in melasma, the gender distribution was more equal in vitiligo. Melasma had a mean DLQI score of 5.64 ± 5.41 and a median score of 4 while vitiligo had a mean DLQI score of 4.13 ± 3.74 and a median score of 3. Conclusion Melasma patients had a higher impairment in quality of life compared to vitiligo patients. The quality of life in both the conditions varied based on age, gender, duration and distribution.

Patient's Mode of Transportation Presented in the Emergency Department of a Tertiary Care Centre, Kavre, Nepal.

Background In many developing countries, emergency medical services, especially pre-hospital emergency care, has long been neglected. It is the major obstacle for provision of timely care. Patients are regularly brought to emergency department by the relatives in taxis, bus or other readily available mode of transportation that lacks emergency medical services. Development the Nepal Ambulance Service established its first proper ambulance service in Nepal in 2011 and Dhulikhel Emergency Medical Services in 2013 at Dhulikhel Hospital, Kathmandu University Hospital. Proper prehospital emergence medical service can improve survival rates. Objective To determine the mode of transportation used by patients to arrive at the emergency department and effectiveness of medical services specific to Dhulikhel Hospital, Kavre, Nepal. Method In this study, 160 patients who arrived to emergency department during one-month period were included. The emergency physicians and paramedics collected data on a predesigned questionnaire regarding demographic details, mode of transport used by the patients to arrive emergency department, reason for not using ambulance, knowledge on emergency medical services at Dhulikhel Hospital and their acceptability for those services. Result Mean age of the patients was 46±18 years and (52%) were men. Out of them, only 31% arrived to the emergency department by ambulance while the rest other patients used other forms of transport such as private vehicles (21%), bus (16%), taxi (13%), motorbike (11%) and van (7%). Among 50 patients who used ambulance, 24% of the patients who used Dhulikhel Hospital ambulance received medical care and trained medical staff services; all patients were satisfied with the services. 155 out of 160 patients mentioned the need of a trained medical personal in ambulance. The mean duration for waiting time for ambulance was 33.78 minutes. The main reasons to not using ambulance were they did not know the ambulance number, ability to find other vehicles easily and having own private vehicle. Conclusion A prominent proportion of patients did not arrive by ambulance to the emergency department and the main reason was that they didn't know the number of ambulance service. Developing three-digit phone number for ambulance service at the local level will make people easier to remember and contact. Similarly, education and training must be developed to improve emergency medical services. These strategies along with team management of patients could significantly improve patient care in Nepal.

Prevalence of Malnutrition in a Rural Residential Sanskrit School in Baglung, Nepal.

INTRODUCTION: Under-nutrition is a condition in which there is inadequate consumption, poor absorption or excessive loss of nutrients. Nepal still faces high chronic as well as acute under-nutrition in children. The following study was conducted a Sanskrit school in rural Baglung to find the prevalence of malnutrition among the children which could reflect the nutritional status of the community. METHODS: Out of 60 students admitted to the school, only 43 were present at the time when we collected our data. Weight was measured with a standard weighing scale and standing height with a measuring tape attached to the wall. Data were filled up in proforma, entered in Microsoft Excel 2013 and were analyzed and indicators calculated with SPSS version 20 using WHO Child Growth Reference data for 5-19 years and macros. RESULTS: Stunting (Z score < -2) was found in 53.5% of the study group and severe stunting (Z score < -3) was found in 25.6%. 12.5% of the 8 children under 10 years in our study had weight-for-age < -2 Z score which indicates underweight. No one was severely underweight. In our study, 2.3% had severe thinness (Z-score < -3), 14% had thinness (Z-score < -2). No one was overweight or obese. CONCLUSIONS: The prevalence of malnutrition was high among the students of the rural Sanskrit school where the study was conducted.

Effectiveness of telerehabilitation interventions in persons with multiple sclerosis: A systematic review.

BACKGROUND: Telerehabilitation, a service delivery model using telecommunications technology to provide therapy at a distance, is used in persons with multiple sclerosis (pwMS), but evidence for their effectiveness is yet to be determined. OBJECTIVE: To investigate the effectiveness and safety of telerehabilitation intervention pwMS. METHOD: A comprehensive literature search was conducted using medical and health science electronic databases. Three reviewers selected potential studies and independently assessed the methodological quality. A meta-analysis was not possible due to heterogeneity amongst included trials, and a qualitative analysis was performed for best evidence synthesis. RESULTS: Ten RCTs and 2 observational studies (n=564 participants) investigated a wide variety of telerehabilitation intervention in pwMS, which included: physical activity; educational, behavioural and symptom management programmes. All studies scored "low to moderate" on the methodological quality assessment implying high risk of bias. Overall, the review found low level evidence for the effectiveness of telerehabilitation on reducing short-term disability and reducing and/or improving symptoms, such as fatigue. There was low level evidence suggesting some benefit of telerehabilitation in improving functional activities; improving symptoms in the longer-term; and psychological outcomes and quality of life. There is limited data on safety, process evaluation and no data on cost-effectiveness of telerehabilitation. CONCLUSIONS: A wide range of telerehabilitation is used in pwMS, however, the quality of evidence on these interventions was low. More robust trials are needed to build evidence about these interventions.

Telerehabilitation for persons with multiple sclerosis. A Cochrane review.

A wide range of telerehabilitation interventions are trialled in persons with multiple sclerosis (pwMS). However, the evidence for their effectiveness is unclear. Aim of the review was to systematically assess the effectiveness and safety of telerehabilitation intervention in pwMS, the types of approaches that are effective (setting, type, intensity) and the outcomes (impairment, activity limitation and participation) that are affected. The search strategy comprised: Cochrane Multiple Sclerosis and Rare Diseases of the Central Nervous System Review Group Specialised Register (up to 9 July, 2014). Relevant journals and reference lists of identified studies were screened for additional data. Selected studies included randomized and controlled clinical trials that compared telerehabilitation intervention/s in pwMS with a control intervention (such as lower level or different types of intervention, minimal intervention; waiting-list controls, no treatment or usual care; interventions given in different settings). Best evidence synthesis was based on methodological quality using the GRADEpro software. Nine RCTs (N.=531 participants, 469 included in analyses) investigated a variety of telerehabilitation interventions in adults with MS. The interventions evaluated were complex, with more than one rehabilitation component and included physical activity, educational, behavioural and symptom management programmes. All studies scored "low" on the methodological quality assessment. Evidence from included studies provides 'low-level' evidence for reduction in short-term disability (and symptoms) such as fatigue. There was also "low-level" evidence supporting telerehabilitation in the longer term for improved functional activities, impairments (such as fatigue, pain, insomnia); and participation. There were limited data on process evaluation (participants'/therapists' satisfaction) and no data available for cost effectiveness. There were no adverse events reported as a result of telerehabilitation intervention. There is limited evidence to date, on the efficacy of telerehabilitation in improving functional activities, fatigue and quality of life in adults with MS. There is also insufficient evidence to support what types of telerehabilitation interventions are effective, and in which setting. More robust trials are needed to build evidence for the clinical and cost effectiveness of these interventions.

Rehabilitation interventions in patients with acute demyelinating inflammatory polyneuropathy: a systematic review.

Acute inflammatory demyelinating polyneuropathy (Guillain-Barré syndrome, GBS) can be a significant cause of new long-term disability, which is thought to be amenable to rehabilitation. Rehabilitation is an expensive resource and the evidence to support its justification is urgently needed. This systematic review presents an evidence-based overview of the effectiveness of various rehabilitation interventions in adults with GBS and the outcomes that are affected. Medline, EMBASE, CINAHL, AMED, PEDro, LILACS and the Cochrane Library were searched up to March 2012 for studies reporting outcomes of GBS patients following rehabilitation interventions that addressed functional restoration and participation. Two reviewers applied the inclusion criteria to select potential studies and independently extracted data and assessed the methodological quality. Included studies were critically appraised using GRADE methodological quality approach. Formal levels of evidence of each intervention were assigned using a standard format defined by National Health and Medical Research Council. Fourteen papers (one systematic review, one randomized controlled trial, one case-control study, five cohort studies and six case series/reports) that described a range of rehabilitation interventions for persons with GBS were evaluated for the "best" evidence to date. One high quality randomised controlled trial demonstrated effectiveness of higher intensity multidisciplinary ambulatory rehabilitation in reducing disability in persons with GBS in the later stages of recovery, compared with lesser intensity rehabilitation intervention for up to 12 months. Four observational studies, further demonstrated some support for improved disability and quality of life following inpatient multidisciplinary rehabilitation up to 12 months. Evidence for uni-disciplinary rehabilitation interventions is limited, with 'satisfactory' evidence for physical therapy in reducing fatigue, improving function and quality of life in persons with GBS. This review provides "good" evidence to support multidisciplinary rehabilitative intervention in adults with GBS; and "satisfactory" evidence for physical therapy in these patients. Evidence for other uni-disciplinary interventions is limited or inconclusive. The gaps in existing research should not be interpreted as ineffectiveness of rehabilitation intervention in GBS. Further research is needed with appropriate study designs, outcome measurement, type of modalities and cost-effectiveness of these interventions.

Systematic review of multidisciplinary rehabilitation in patients with multiple trauma.

BACKGROUND: Multiple trauma is a cause of significant disability in adults of working age. Despite the implementation of trauma systems for improved coordination and organization of care, rehabilitation services are not yet routinely considered integral to trauma care processes. METHODS: MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, Allied and Complementary Medicine, Physiotherapy Evidence Database, Latin American and Caribbean Literature on Health Sciences and Cochrane Library databases were searched up to May 2011 for randomized clinical trials, as well as observational studies, reporting outcomes of injured patients following multidisciplinary rehabilitation that addressed functional restoration and societal reintegration based on the International Classification of Functioning, Disability and Health. RESULTS: No randomized and/or controlled clinical trials were identified. Fifteen observational studies involving 2386 participants with injuries were included. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach assessed methodological quality as 'poor' in all studies, with selection and observer bias. Although patients with low functional scores showed improvement after rehabilitation, they were unable to resume their pretrauma level of activity. Their functional ability was significantly associated with motor independence on admission and early acute rehabilitation, which contributed to a shorter hospital stay. Injury location, age, co-morbidity and education predicted long-term functional consequences. Trauma care systems were associated with reduced mortality. The gaps in evidence include: rehabilitation settings, components, intensity, duration and types of therapy, and long-term outcomes for survivors of multiple trauma. CONCLUSION: Rehabilitation is an expensive resource and the evidence to support its justification is needed urgently. The issues in study design and research methodology in rehabilitation are challenging. Opportunities to prioritize trauma rehabilitation, disability management and social reintegration of multiple injury survivors are discussed.

Multidisciplinary care for Guillain-Barré syndrome.

BACKGROUND: Guillain-Barré syndrome (GBS) can be a significant cause of new long-term disability, which is thought to be amenable to multidisciplinary care. However, the evidence base of its effectiveness is unclear. AIM: The aim of this systematic review is to assess the effectiveness of multidisciplinary care in adults with GBS, the types of approaches that are effective (setting, type, intensity) and the outcomes that are affected. METHODS: The search strategy comprised: The Cochrane Neuromuscular Disease Group Specialized Register and the Cochrane Central Register of Controlled Trials; MEDLINE, EMBASE, AMED, PEDro, LILACS and CINAHL (up to May 2010). Selected studies included randomized and controlled clinical trials that compared multidisciplinary care in GBS with a control (routine local service, lower level of intervention); or studies that compared multidisciplinary care in different settings or at different levels of intensity of therapy. Best evidence synthesis was based on methodological quality. Three observational studies were also reported but they make limited contribution to evidence base synthesis. RESULTS: No randomized or controlled clinical trials were identified. Evidence from three low-quality observational studies provide some support for improved disability in the short term (6 months) with high intensity rehabilitation; and for improved participation and quality of life. CONCLUSION: The gaps in existing research should not be interpreted as ineffectiveness of multidisciplinary care in GBS. Appropriate and methodologically robust study designs, responsive outcome measures; and more research in the setting, type and intensity of rehabilitation are needed.

Expression of tachykinins and their receptors in plaque psoriasis with pruritus.

UNLABELLED: BACKGROUND Various mediators of pruritus have been suggested that might be responsible for the mechanism of pruritus in psoriasis. OBJECTIVES: To study the expression levels of members of the tachykinin family, substance P and neurokinin (NK) A and their receptors, NK-1 and NK-2, in psoriasis and to correlate their expression with the intensity of pruritus. A possible correlation with chronic stress and depression was also evaluated. METHODS: Biopsies were obtained from 28 patients with chronic plaque psoriasis; the majority had pruritus. The samples were taken from lesional and nonlesional areas on the back and also from 10 healthy controls, for immunohistochemistry staining, and from lesional skin for radioimmunoassay. Prior to biopsy, the clinical severity of the psoriasis of each patient was assessed by the Psoriasis Area and Severity Index (PASI) and the intensity of pruritus was measured by using a visual analogue scale (VAS). Levels of depression and stress were measured using Beck's Depression Inventory (BDI) and the salivary cortisol test, respectively. RESULTS: Substance P-, NKA- and NK-2 receptor-immunoreactive nerves, and non-neuronal inflammatory cells positive for substance P and NKA and their respective receptors, NK-1 and NK-2, were numerous in psoriasis compared with healthy controls. The numbers of substance P-positive nerves and NK-2 receptor-positive cells in lesional skin were significantly correlated to pruritus intensity. The cortisol ratio was inversely correlated with the number of NK-1 receptor-immunoreactive inflammatory cells in lesional and nonlesional psoriasis skin. There was also a positive correlation between the BDI score and the number of substance P-positive cells in nonlesional skin and with NK-1 receptor-positive cells in lesional and nonlesional skin. CONCLUSIONS: Tachykinins may play a role in psoriasis per se, in addition to pruritus in this disease. Targeting the combined NK-1 and NK-2 receptors might be a possible treatment.

Responses to intradermal injections of substance P in psoriasis patients with pruritus.

BACKGROUND: Various mediators have been suggested for the pathogenesis of pruritus in psoriasis. METHODS: To investigate cutaneous responses of substance P in pruritic lesional and nonlesional areas of psoriasis patients and in healthy controls, substance P, saline and histamine were injected intradermally. After each injection, pruritus, flare and wheal were recorded. RESULTS: There was no statistical difference in the latency period, duration, area under the curve and maximum intensity of pruritus evoked by substance P (10(-5) and 10(-6) mol/l) between psoriasis and healthy control skin. Substance P (10(-5) mol/l) induced a tendency to a greater intensity of pruritus in lesional compared to nonlesional psoriatic skin (p = 0.08). Histamine produced a shorter itch latency period (p < 0.05) and a lower maximum intensity of pruritus (p = 0.05) in lesional psoriasis skin than in healthy control skin. No significant difference in flare area was observed between the psoriasis patients and healthy controls. The histamine-induced wheal was smaller in psoriasis patients than in healthy individuals (p < 0.05). CONCLUSION: Intradermally injected substance P induced pruritus, flare and wheal in psoriasis patients. However, these responses did not differ significantly from those of the healthy controls.

Redesigning care for chronic conditions: improving hospital-based ambulatory care for people with osteoarthritis of the hip and knee.

BACKGROUND: Osteoarthritis of the hip and knee is a highly prevalent chronic condition in Australia that commonly affects older people who have other comorbidities. We report the pilot implementation of a new chronic disease management osteoarthritis service, which was multidisciplinary, evidence-based, supported patient self-management and care coordination. METHODS: A musculoskeletal coordinator role was pivotal to service redesign and osteoarthritis pathway implementation. Impact evaluation included: service utilization, patient and general practitioner service experience, a 'before and after' audit of clinician adherence to recommendations, and 3- and 6-month patient health outcomes (pain, physical function, patient and physician global health (Visual Analogue Scale), disability (Multi-Attribute Prioritisation Tool), Partners in Health Scale and body mass index). RESULTS: A total of 123 patients, median age of 66 years, were assessed. Documentation of osteoarthritis assessment and management improved for all parameters. At 3 months there were improvements in self-reported pain (P < 0.001), global function (P < 0.001), physician and patient reported global health (P < 0.001), Partners in Health Score (P < 0.001) and Hip and Knee Multi-Attribute Prioritisation Tool score (P < 0.014). Body mass index did not improve. Patients and general practitioners reported positive experiences, but there was variable uptake of recommendations by patients. The main factors influencing uptake of recommendations were access block to community services in the first 3 months and patient preferences for therapy. The cost implications for implementation were low. CONCLUSION: The osteoarthritis service model is feasible to implement, is well received by patients and staff, and provides a template for translation into other settings.

Measuring performance to drive improvement: development of a clinical indicator set for general medicine.

BACKGROUND: There are delays in implementing evidence about effective therapy into clinical practice. Clinical indicators may support implementation of guideline recommendations. AIM: To develop and evaluate the short-term impact of a clinical indicator set for general medicine. METHODS: A set of clinical process indicators was developed using a structured process. The indicator set was implemented between January 2006 and December 2006, using strategies based on evidence about effectiveness and local contextual factors. Evaluation included a structured survey of general medical staff to assess awareness and attitudes towards the programme and qualitative assessment of barriers to implementation. Impact on documentation of adherence to clinical indicators was assessed by auditing a random sample of medical records before (2003-2005) and after (2006) implementation. RESULTS: Clinical indicators were developed for the following areas: venous thromboembolism, cognition, chronic heart failure, chronic obstructive pulmonary disease, diabetes, low trauma fracture, patient written care plans. The programme was well supported and incurred little burden to staff. Implementation occurred largely as planned; however, documentation of adherence to clinical indicators was variable. There was a generally positive trend over time, but for most indicators this was independent of the implementation process and may have been influenced by other system improvement activities. Failure to demonstrate a significant impact during the pilot phase is likely to have been influenced by administrative factors, especially lack of an integrative data documentation and collection process. CONCLUSION: Successful implementation in phase two is likely to depend upon an effective data collection system integrated into usual care.

Patients' perspective of pruritus in chronic plaque psoriasis: a questionnaire-based study.

BACKGROUND: Pruritus in psoriasis patients has not been regarded as a major symptom. Objective To study the pattern of pruritus in chronic plaque psoriasis. METHODS: A questionnaire was sent out to 109 patients with a diagnosis of chronic plaque psoriasis, who attended our outpatient departments during the period of January 2006 to January 2007. RESULTS: Out of 109 patients, 80 patients (74%) answered the questionnaire. Pruritus was found in 80% of the patients, with an intensity of 5.2 +/- 2.6 (+/-SD) using a visual analogue scale (0-10). The frequency and intensity of pruritus were higher in women. Lower leg and scalp were reported to be the most commonly affected sites. Major aggravating factors for pruritus were stress and dryness of skin. Sun, sleep and vacation could relieve pruritus. The most common antipruritic treatments used by the patients were topical steroids, topical vitamin D, emollients and ultraviolet light therapy, whereas antihistamines were used by a small number of patients. Mood, concentration and sleep were negatively affected by pruritus. CONCLUSION: Pruritus is a common symptom in patients with chronic plaque psoriasis.

Cysticercosis in Nepal: a histopathologic study of sixty-two cases.

Human cysticercosis, an infection caused by larvae of Taenia solium, is a major public health problem in many developing countries. Sixty-two of 23,402 biopsy cases have been detected as cysticercosis in the last 5 years in Patan Hospital. Most (82%) of the patients presented with solitary skin nodules, another 10% with nodules in the oral mucosa, and 8% in the breast. Forty cases were identified from the Kathmandu valley and the rest from outside Kathmandu. Most patients were younger than 30 years of age (mean, 21+/-11 years). Statistically, there was no difference between males (0.28%) and females (0.24%). The average size of cysticercosis was 19 mm in diameter, and the histology of cysticercosis showed fibrous walled cysts covered by several layered epithelioid cells with a few Langhans' giant cells and infiltration of eosinophils without caseous necrosis. These cysticercosis findings from an endemic area will be helpful for doctors who examine immigrant patients in nonendemic areas.

Histopathology of typhoid enteritis: morphologic and immunophenotypic findings.

Enteric fever is a systemic illness caused by Salmonella infection, with S. typhi, S. paratyphi, and S. enteritidis being the most common serotypes. Humans are the only reservoir for S. typhi, and its predilection for the ileum is due to the fact that organisms enter the body by translocation across specialized Peyer's patch epithelium and then proliferate in the mucosal macrophages. The lesions in bowel and mesenteric lymph nodes are distinctive and mimic Kikuchi-Fujimoto disease and Rosai-Dorfman disease as well as infections caused by some non-salmonella bacteria. The four cases presented in this report, two culture-confirmed, all exhibited ileal mucosal hypertrophy caused by a neutrophil-poor monocyte/macrophage-rich hyperplasia. Though diffuse areas were present, much of the lesional proliferation was nodular, representing macrophage infiltration and colonization by the monocytes and macrophages. Immunophenotypic studies, which showed a CD68+, lysozyme+, UCHL-1+, OPD4-, CD4-, s100- profile, were helpful in distinguishing these lesions from other processes, including Kikuchi-Fujimoto disease and Rosai-Dorfman disease. Although rare in developed countries, enteric fever should be considered in any patient with recent travel to endemic areas and in the context of illness thought to be related to contaminated foods.
