Management and attitudes about IPF (Idiopathic Pulmonary Fibrosis) among physicians from Latin America

Background: The aim of our study was to assess current practice patterns and attitudes towards diagnosis and management of idiopathic pulmonary fibrosis (IPF) patients in Latin America. Methods: A Cross-sectional survey was developed and up to 455 physicians were enrolled. We used a rigorous method of validation using the translated version of the AIR Survey. Results: Mean age was 47.5 years (SD 12.6) with 20.4 years (SD 12.3) of practice. In around 30% of physicians were reported access to radiologist, pathologist and multidisciplinary team. Despite almost all physicians reported that (ATS/ERS/JRS/ALAT) guidelines are useful, half of them prescribed corticoids for treatment of disease. Most respondents (69.9%) reported cough as the presenting symptom. Around 80% considered IPF to be an important clinical disorder, and felt that identifying patients at risk for IPF was important or extremely important. However, only 59.7% felt confident in managing patients with IPF, and similar numbers (60.8%) felt confident about their knowledge. Pulmonologist have more confidence and management of IPF that no pulmonologist. Conclusion: The results of this survey of Latin American physicians could help to fill gaps regarding awareness, management and treatment of IPF and improve earlier diagnosis of IPF

Autoimmune thyroid disease and urticarial vasculitis: is there a significant association?

Little is known about the association of urticarial vasculitis (UV) with thyroid autoimmunity. The latter has been mostly described in the setting of patients with chronic spontaneous urticaria (CSU). In this letter to the editor, we compare UV and CSU through retrospective analyses, which reveal that 41.7% patients with UV presented antithyroperoxidase (anti-TPO) and/or antithyroglobulin antibody (ATA) above the reference range, while only 4% patients with CSU had these antibodies elevated. There is a moderately strong association assessed by the Phi coefficient (φ = 0.420, p = 0.004). Further research is needed to appropriately address the relationship between UV and thyroid autoimmunity and explore any potential underlying pathophysiological process between both diseases

Obstructive sleep apnea knowledge and attitudes among recent medical graduates training in Ecuador

Background: We aimed to assess recent Latin American medical school graduates’ knowledge and attitudes about OSA and examine whether their knowledge and attitudes about OSA differed from practicing physicians. Methods: Recent medical graduates completed the Spanish translation of the OSA Knowledge and Attitudes (OSAKA) questionnaire at the 2013 national primary-care residency-placement meeting in Ecuador. The OSAKA includes 18 knowledge and five attitudinal items about OSA. We compared recent graduates’ data with data collected in 2010–2011 from practicing physicians using chi-square tests of associations among categorical variables and analysis of variance of differences in mean knowledge and attitude scores. Unadjusted logistic regression models tested the odds that recent graduates (vs. practicing physicians) answered each item correctly. Results: Of 265 recent graduates, 138 (52.1%) were male, and mean age was 25.9 years. Although mean knowledge was low overall, scores were lower for recent graduates than for the 367 practicing physicians (53.5% vs. 60.4%; p < 0.001). Practicing physicians were significantly more likely to answer specific items correctly with one exception—recent graduates were more likely to know that < 5 apneas-hypopneas/h is normal (OR 1.47, 1.03–2.07). Physicians in practice attributed greater importance to OSA as clinical disorder and the need for identifying patients with OSA; but recent graduates reported greater confidence in managing patients with OSA and CPAP. Conclusions: OSA-focused educational interventions during medical school should help to improve recent medical graduates’ abilities to diagnose and treat OSA. We recommend a greater number of hours of medical students’ exposure to sleep education

Checklist for a complete chronic urticaria medical history : an easy tool

ABSTARCT: Existing guidelines do not offer a quick, efficient alternative to the patient's recollection of relevant clinical features during anamnesis and physical examination for chronic urticaria (CU). This study aimed to identify specific items reflecting the main characteristics of CU that should be included in a comprehensive medical history for patients with CU. We also aimed to clarify possible eliciting factors for CU to support accurate diagnosis of the disease. METHODS: A panel of postgraduate dermatologists conducted a literature search for relevant studies on CU using Medline, the Cochrane database, and PubMed. RESULTS: We identified82 articles from which we drew a collection of items to inform development of an easy-to-use checklist and collection of items that should be included in a correct medical history. The final version of the checklist included42 items across two areas: essential clues for anamnesis and diagnosis of CU; and typical symptoms/parameters or characteristics according to subtype, etiology, and laboratory findings. Items included time of disease onset; duration, shape, size, color, and distribution of wheals; associated angioedema; atopy; and triggering factors. CONCLUSIONS: Our guide provides an easy-to-use tool to support clinicians to focus, orient themselves, and save time in medical consultations for CU, allowing better diagnosis and management of this disease

Omalizumab for chronic urticaria in Latin America

Abstract Background Chronic urticaria (CU) is defined as the spontaneous appearance of wheals, with or without angioedema, persisting for ≥6 weeks. Chronic Spontaneous Urticaria (CSU) is a type of CU which affects 0.5–1 % of the global population, but it represents a high burden to patients. In recent years, omalizumab is available as treatment of disease. Our aim is to extend previous findings, analyzing effects of omalizumab on symptoms in Latin American patients with CSU. Methods Retrospective analysis of patients treated with omalizumab in Cuenca-Ecuador. 150 mg omalizumab was administered every 4 weeks, and its effects were measured by Urticaria Activity Score (UAS) at baseline and each month in follow up. Complete response was defined as a UAS of 0 or 1, and partial response was classified as a UAS of 2 or more. Also, demographic and clinical variables were collected. Descriptive analyses were employed. Response rates were summarized as counts and percentages after 3 and 5 months. Related Samples Wilcoxon signed rank tests were used to compare UAS at baseline and after 3 months. P values <0.05 indicated statistical significance. Results 26 subjects were enrolled, almost half were female individuals (57.7 %), with mean age 47.8 years (range, 18–81 years). Mean duration of CU after diagnosis was 23.3 months (range, 2–180 months). Mean UAS at baseline was 5.7 points (range, 4–6 points). Nine patients (34.6 %) completed 3 months of treatment (33 % reported a complete response), with a mean difference in UAS of 3.33 (p = 0.01). Four patients completed 5 months of treatment (75.0 % showed a complete response). All patients previously treated with first-generation antihistamines plus corticosteroids showed no responses at neither 3 nor 5 months of treatment. Conclusion Omalizumab is an effective treatment for patients with CU. It is necessary to conduct some future investigations where we can establish if 150 mg could be an option in developing countries

Urticaria as initial finding of a patient with carcinoid tumor

Background Typical carcinoid syndrome is characterized by flushing, abdominal pain and diarrhea and occurs in <10 % of carcinoid tumor patients. Very rarely, initial signs include skin manifestations. Our purpose is to highlight cutaneous manifestations in the diagnosis and assessment of a patient with atypical manifestation of type I gastric carcinoid tumor.Case presentation A 50-year-old woman presented with anemia, chronic urticaria and angioedema. Urticaria was triggered principally by seafood and appeared in the first hour after. Urticaria Activity Score 7 was 24, and quality of life (CU-Q2oL) was 3.61. P. Laboratory findings showed anemia, diminished iron, ferritin, and vitamin B12, with increased gastrin and anti-parietal cell antibody levels. 15 gastric carcinoids 5 mm in diameter were observed in the greater curvature of the stomach during gastric endoscopy and confirmed by biopsy, suggesting that this patient had type I gastric carcinoids. Four additional tumors were found in the small intestine upon examination via video capsule. Endoscopic argon plasma therapy was performed. The patient experienced definitive improvement in quality of life and urticaria activity score.Conclusion This patient, whose principal symptoms were anemia, urticaria and angioedema, was found to have atypical carcinoid syndrome, with tumors located in the stomach. Allergists, immunologists, internists and primary care physicians should consider the possibility of neuroendocrine malignancies, specifically type I carcinoid tumors, when evaluating patients with urticaria, and consider screening patients with chronic urticaria for elevated anti-parietal cell antibody levels.

Are natural analgesic products safe in patients with allergy to non-steroidal anti-inflammatory drugs?

Background: Nonsteroidal anti-inflammatory drugs (NSAID)-induced hypersensitivity reactions can be clinically apparent with asthma, rhinosinusitis, anaphylaxis or rash. Although natural anti-inflammatory products can have similar components, they are not subjected to rigorous quality control standards. Case report: The case is presented of a 22-year-old female with NSAID allergy who attended with facial and laryngeal angioedema associated with pruritus in eyelids and pharynx. She developed these symptoms fifteen minutes after taking an over-the-counter (OTC) natural anti-inflammatory product. She received treatment with epinephrine, antihistamines and corticosteroids. Conclusion: Different natural anti-inflammatory products are freely available both OTC and online. Some contain dangerous substances that can cause important, and even lethal. side effects. Allergologists, dermatologists and general practitioners should be able to recognize that the consumption of these products, which is widely spread, can cause angioedema

Information and communication technology use in asthmatic patients: a cross-sectional study in Latin America

Rapid diffusion, low cost and broad availability of information and communication technologies (ICTs) make them an attractive platform for managing care, communication and interventions in asthma. There is little information in Latin America about usage frequency of ICTs in asthmatic patients. The analysis undertaken consisted of an observational, cross-sectional study that aimed to identify the frequency and type of ICTs most often used by asthmatics. The Spanish version of the Michigan questionnaire was employed in five Latin American countries. Age and educational level was categorised. Logistic regression was performed among these groups concerning the frequency of ICT usage and the level of interest shown in seeking and receiving information about asthma. In total, 673 asthma patients were surveyed. The mean age was 43.44 years. Over two-thirds of the participants were female (68.4%). The most used ICT was the short message service (SMS) (69.9%). SMS and E-mail are useful tools for communicating (i.e. receiving and seeking information) with all asthma patients, irrespective of their age. WhatsApp (61.5%) and Facebook (32.0%) were rated as being the most interesting channels of communication for receiving information. Regression analysis showed that younger asthmatics and asthmatics with higher educational levels were most likely to use almost all forms of ICTs. ICTs are generally an attractive platform for managing care, communication and interventions to improve asthma care. SMS and E-mail were found to be the preferred ICT forms among users. However, social media forms such as WhatsApp and Facebook may also be appropriate for certain types of patient
