RESUMEN

We have created a bleeding leg simulator using inexpensive and readily available materials to teach civilians in resource-poor settings how to control exsanguinating hemorrhage until the patient can be brought to the hospital, as commercially available mannequins are often too expensive in these settings. Items used include a leg of lamb, IV tubing, IV fluids, and food coloring. The model was consistently rated as ''nearly - real'' to ''life like'' by ten physicians and surgeons, cost less than fifty dollars to make, and provided a fairly realistic model for teaching hemorrhage control.

RESUMEN

BACKGROUND: In Egypt more than one-third of colorectal cancer (CRC) cases occur in individuals aged 40 years and younger, and are diagnosed at advanced stages; currently, CRC screening is not done as a routine part of preventive care. To lay the foundation for the development of a CRC multilevel screening program in Egypt, this qualitative study aimed to explore the perspectives of Egyptian physicians. MATERIALS AND METHODS: The PRECEDE-PROCEED model, which focuses on predisposing (intrapersonal), reinforcing (interpersonal), and enabling (structural) factors inherent in health behaviors, served as our theoretical framework. Primary health care physicians, oncologists, and gastroenterologists practicing in Alexandria, Egypt, participated in 1 one-hour semistructured interview. Interviews were audio recorded, transcribed, translated into English, and analyzed by thematic analysis. RESULTS: Seventeen physicians participated (n = 8 specialists and n = 9 primary care physicians). Barriers to CRC screening included socioeconomic status, a lack of emphasis on prevention, fear, and cost (predisposing); a belief that only high risk patients should be screened and a lack of confidence in providers to perform and interpret screening tests appropriately (reinforcing); and cost, lack of availability of the tests, and inadequate training for laboratory technicians and providers (enabling). Potential facilitators included implementing a media campaign emphasizing early detection, curability and prevention (predisposing); educating physicians and eliciting physician engagement (reinforcing); and decreasing costs, making screening tests widely available, and providing well-trained providers (enabling). CONCLUSION: A CRC screening program is needed in Egypt, and to be successful it would likely need to address barriers at multiple levels. IMPLICATIONS FOR PRACTICE: In Egypt, colorectal screening is not a routine part of preventive care, and colorectal cancer is often diagnosed at an advanced stage in individuals aged 40 years or younger. Screening can prevent and detect colorectal cancer in its early stages, but before designing any screening program, understanding the context is important as cultural beliefs may impact the acceptability of screening methods. By exploring the perspectives of Egyptian physicians, this study found important insights into how screening program components should be considered in the Egyptian culture and lays the foundation for the development of a multilevel colorectal screening program in Egypt.

RESUMEN

BACKGROUND: Traumatic fractures are common in sub-Saharan Africa, a region with a shortfall of orthopaedic surgeons, and can result in morbidity if not appropriately managed. WhatsApp is an encrypted smartphone application and ubiquitous in sub-Saharan Africa. The objective of this study was to assess the use of WhatsApp as a mobile health platform to support fracture management by non-orthopaedic doctors in Cape Town, South Africa. STUDY DESIGN: A WhatsApp orthopaedic referral group was created between non-orthopaedic doctors from community health clinics and the orthopaedic team from a first-level hospital to manage traumatic fractures. Non-orthopaedic doctors posted cases on the orthopaedic referral group and the orthopaedic team provided advice. Traumatic fracture data from January 1 to June 30, 2018 were analyzed and outcomes included response time, management advice, and treatment by facility level. RESULTS: Seventy-two non-orthopaedic doctors posted 731 cases of traumatic fractures to the 5-member orthopaedic team. Six hundred and sixty-one (90%) cases were responded to within 1 hour. Three hundred and fifty-four (48%) patients were treated successfully by non-orthopaedic doctors at community health clinics, 288 (39%) were treated by the orthopaedic team at the first-level hospital, and 89 (12%) were referred directly to an orthopaedic subspecialist at a third-level hospital. CONCLUSIONS: The WhatsApp orthopaedic referral group provided a free telementoring platform for non-orthopaedic doctors to successfully manage traumatic fracture cases at community health clinics. This type of mobile health platform can be applicable to other resource-limited settings if disease burden is high and specialists are scarce.

RESUMEN

AIMS: To identify the role of securin (PTTG) as a prognostic marker in invasive breast carcinoma and its possible relation to ki67 and to evaluate the use of ImmunoRatio® as a tool for calculating ki67 and securin labelling indices. METHODS: Securin and ki67 immunohistochemical staining were performed on tissue microarray sections representative of 118 patients diagnosed with invasive breast carcinoma from 2005 to 2011. Assessment of immunohistochemical staining was carried out using both visual counting and ImmunoRatio®. The 118 cases were categorized into 2 groups according to their clinical outcome; the first group (G1) (n=77) comprised patients who were disease-free while the second group (G2) (n=41) included patients who developed either recurrence and/or metastasis at the end of 24 months follow-up duration. RESULTS: Both securin and ki67 labelling indices (LIs) obtained by visual counting were significantly higher in G2, while only securin LIs acquired by ImmunoRatio® were significantly higher in G2. Securin assessment by visual counting was the most accurate (AUC=0.775) in identifying patients who will likely suffer from recurrence and/or distant metastasis. Pearson correlation showed r=0.638, p<0.001 for Ki67 and r=0.671, p<0.001 for securin. Linear regression analysis showed a significant correlation between ki67 and securin, B=1.75, p<0.001. CONCLUSION: The present results suggest that securin may add to the prognostic value of ki67 in highlighting intra-tumoural heterogeneity in invasive breast carcinoma patients with poor clinical outcome. In addition, the study showed that since securin has a visual counting cutoff with more than 1%, making it easier to use as a breast cancer biomarker in conjunction with ki67 to predict the outcome of the cases more accurately than using only ki67. However, a multivariate analysis on a larger cohort of patients is mandatory to test its potential prognostic value.

RESUMEN

OBJECTIVE: To determine whether antibiotics are necessary for all minor wounds presenting to the Accident and Emergency Department at a tertiary care Centre in Pakistan. METHODS: One hundred and five patients presenting to the Accident & Emergency Department, Jinnah Postgraduate Medical Centre, Karachi, with open wounds were included in the study and divided into two: Groups A (study) and B (control), with Group-A receiving conservative therapy. Eighty-four patients were included in the final analysis as the rest were lost to follow up. Follow up was done after one week to see how many patients had developed infection. RESULTS: The average age of patients was 27.3 +/-9.7 years with similar baseline characteristics. From these, 51% had superficial wounds; average number of wounds was 1.63 +/-0.99, with an average length of 2.7 +/-1.6 cm. A total of 10 out of 84 patients developed infection at 7-10 days after presentation to the A&E. From these, 3 patients receiving conservative treatment (A, 10%, OR=0.107), and seven patients receiving prophylactic antibiotics (B, 12.96%, OR=0.149) developed an infection. Calculated odds ratio for increased risk of infection in Group-A = 0.72. CONCLUSION: A conservative approach to antibiotic prescription for minor trauma may be appropriate despite absence of strict asepsis during emergency wound care.

RESUMEN

Background: Advanced stage non-small cell lung cancer (NSCLC) is a heterogenous disease, yet, with the exception of targeted therapies, most guidelines recommended uniform treatment irrespective of tumor burden or sites of metastases and this may explain, in part, the wide range of responses to same lines of therapy. Aim of work: In this work we tried to explore the effect of metastatic sites in on overall survival (OS), in an unselected group of Non-small cell lung cancer patients who received different treatments line. Methods: A retrospective analysis was performed on patients with stage IV NSCLC who received systemic treatment at UAB Cancer Center (NCI designated comprehensive cancer center) between 2002 to 2012. The details of sites of metastases, systemic therapy and overall survival were recorded for each patient. Result: In 409 patients who received systemic treatment, there was statistically significant lower OS in those presenting with liver metastases (p<0.001), adrenal metastases (p=0.011) and metastases to abdominal lymph nodes (p=0.014). There was no statistically significance difference in OS in patient presenting with pleural metastases or effusion (p=0.908), metastases to heart or pericardium (p=0.654), metastases to bone (p=0.281), brain (p=0.717) or skin and subcutaneous tissue (p=0.642). Conclusion: Intra-abdominal metastases confer a particularly poor prognosis in stage IV NSCLC treated with systemic therapy and may identify patients in whom aggressive treatment beyond first line therapy is not appropriate.

RESUMEN

BACKGROUND & OBJECTIVE: Acute gastroenteritis is generally considered a self-limiting illness that does not require the use of antibiotics. However, many emergency departments in the country frequently prescribe antibiotics to patients presenting with diarrhoea. This review attempts to determine whether this practice is reasonable. Our objective was to determine the role of antimicrobials in the empiric management of acute gastroenteritis. METHODS: The online data base "PubMed", as well as the World Wide Web, were searched for relevant articles (RCTs, Reviews, Prospective studies, etc.) with key words such as "gastroenteritis AND antibiotics", "Management AND gastroenteritis", "Treatment AND diarrhoea" etc. and covered the years 1960-2016. Fifty articles were studied, of which 43 were chosen on the basis of relevance for qualitative assessment. RESULTS: The articles reviewed for this paper suggest that antimicrobial therapy is not appropriate for the majority of cases of (uncomplicated) gastroenteritis, as risks (antibiotic-associated diarrhoea, hypersensitivity reactions, etc.) outweigh benefits. However, there are instances where antibiotics are clearly indicated. Further, it is noted that there have not been any recent trials to clarify the role of antimicrobials in adult diarrhoeal illness. CONCLUSIONS: The focus in management of patients presenting with diarrhoea in the Emergency Department should be on rehydration and that only certain patients, such as those with fever or dysentery, or those with an impaired immune response should receive empiric antimicrobial therapy. More studies are needed to determine in what instances antimicrobials are of greatest benefit, so that adverse effects of rampant antibiotic prescription can be curtailed.

RESUMEN

Involuntary migration is a crucially important global challenge from an economic, social, and public health perspective. The number of displaced people reached an unprecedented level in 2015, at a total of 60 million worldwide, with more than 1 million crossing into Europe in the past year alone. Migrants and refugees are often perceived to carry a higher load of infectious diseases, despite no systematic association. We propose three important contributions that the global health community can make to help address infectious disease risks and global health inequalities worldwide, with a particular focus on the refugee crisis in Europe. First, policy decisions should be based on a sound evidence base regarding health risks and burdens to health systems, rather than prejudice or unfounded fears. Second, for incoming refugees, we must focus on building inclusive, cost-effective health services to promote collective health security. Finally, alongside protracted conflicts, widening of health and socioeconomic inequalities between high-income and lower-income countries should be acknowledged as major drivers for the global refugee crisis, and fully considered in planning long-term solutions.

RESUMEN

The treatment of advanced renal cell carcinoma (RCC) has advanced significantly over the last two decades. This multicenter study was designed with the primary objective to evaluate the efficacy and safety of sorafenib as first-line treatment in patients with advanced or metastatic RCC in the Middle East, who were considered to be ineligible for other approved first-line therapies. A total of 75 eligible patients from 8 centers in the Middle East were included in this study. The patients comprised 48 men and 27 women, with a median age of 52 years (range, 19-78 years). A total of 50 patients had clear cell carcinoma, 17 had papillary carcinoma and 8 had other pathological subtypes. At enrollment, 55 of the 75 patients had undergone previous nephrectomy. A total of 67 patients presented with metastatic disease, while 8 patients had regional residual lesions or local recurrence. The patients were treated with 400 mg oral sorafenib twice daily on a continuous basis as a single agent. Treatment was discontinued upon disease progression, prohibitive toxicity, surgical complications, loss to follow-up, or refusal to continue therapy. The median treatment duration was 21 weeks (range, 1-137 weeks). Sorafenib was tolerated by the majority of the patients. Grade 3/4 hand-foot syndrome occurred in 17 patients; diarrhea, elevated liver enzymes and fatigue were observed in 3 patients each; and grade 3/4 vomiting, hypertension and anemia, in 1 patient each. Of the 75 patients included in this study, 60 were evaluable for response. One patient achieved a complete response for 91 weeks and 6 patients exhibited a partial response (median duration of 23 weeks) with an overall response rate of 11.7%. Disease stabilization occurred in 37 patients (61.7%). Thus, disease control was achieved in 44 of the 60 patientrs (73%). At a median follow-up period of 53.5 weeks (range, 8.5-192 weeks), an intention-to-treat analysis demonstrated a median time-to-disease progression of 25.7 weeks, with a median overall survival of 54.8 weeks. In conclusion, sorafenib was found to be tolerable and effective as first-line therapy in patients with advanced RCC.

RESUMEN

RF ablation (RFA) is used for thermal ablation of tumors in which the RF electrode is placed in the tissue under image-guidance. Because of the good tumor visibility and the lack of ionizing radiation, MR-guided RFA is the method of choice. Additionally, with the help of MR thermometry the RF ablation can be monitored during the intervention. Unfortunately, the imaging of an MR scanner is highly sensitive to interferences caused by external electrical signals. In this paper the high-power RF ablation signal of a commercially available medical therapy device is made MR-compatible. A design of a low-pass filter with high-power compatibility is presented. The filter performance is demonstrated by means of simulations and measurements.

RESUMEN

BACKGROUND: Multiple concepts of combined modality therapy for locally advanced inoperable non-small cell lung cancer have been investigated. These include induction chemotherapy, concomitant chemo-radiotherapy, and radiation only. To date, combined modality therapy specially the use of concomitant chemo-radiotherapy has led to promising results and was shown to be superior to radiotherapy alone in phase II studies. However the optimum chemo-therapeutic regimen to be used as well as the benefit of induction chemotherapy before concomitant chemo-radiotherapy are yet to be determined. Based on these observations, we investigated the use of paclitaxel and carboplatin concomitantly with radiotherapy and the benefit of prior two cycles induction chemotherapy. MATERIALS AND METHODS: In this trial 60 patients with locally advanced inoperable non small cell lung cancer, good performance status and minimal weight loss have been randomized into 3 groups each of 20 patients. Group A received induction 2 cycles paclitaxel (175 mg/m2) and carboplatin (AUC 6) on day 1 and 28th followed by concomitant paclitaxel (45 mg/m2) and carboplatin (AUC 2) weekly with radiotherapy. Group B received concomitant carboplatin, paclitaxel (same doses as in group A) and radiotherapy with no prior induction chemotherapy. Group C received only radiotherapy to a total dose of 60 Gy in conventional fractionation. RESULTS: A total of 60 patients were enrolled in this study between 1998 and 2000. Pretreatment characteristics, including age, gender, performance status, histological features and stage were comparable in each group. The incidence of oesophagitis was significantly higher in group A and B than in group C (p=0.023). Hematological toxicities was also significantly higher in group A & B than in group C (p=0.003). The response rate was significantly higher in group A and B than in group C (75%, 79%, and 40% respectively) (p=0.020). The time to in-field progression was significantly higher in group B as compared to group A (48% vs. 32% failure in 2 years respectively) (p=0.000). The median 2 year survival was significantly higher in group A and B than in group C (p=0.039) but no statistical difference was seen between group A and B. CONCLUSION: Combined chemo-radiotherapy resulted in better response and survival as compared to conventional radiotherapy in the treatment of locally advanced nonsmall cell lung cancer. Early initiation of radiation with concomitant chemotherapy resulted in prolonged time to infield progression. On the other hand, two cycles of induction chemotherapy did not show any significant difference regarding the response or survival. Weekly paclitaxel and carboplatin plus radiotherapy is a well tolerated regimen for outpatients with encouraging results.
