RESUMEN
The visualization of black pigment during EBUS-TBNA suggests a relapse of melanoma. This case highlights the value of EBUS-TBNA in diagnosing metastatic melanoma, particularly when the macroscopic appearance of the aspirate suggests the diagnosis.
RESUMEN
BACKGROUND: Twin registries and cohorts face numerous challenges, including significant resource allocation, twins' recruitment and retention. This study aimed to assess expert feedback on a proposed pragmatic idea for launching a continuous health promotion and prevention programme (HPPP) to establish and maintain twin cohorts. DESIGN: A qualitative study incorporating an inductive thematic analysis. SETTING: Tehran University of Medical Sciences. PARTICIPANTS: Researchers with expertise in twin studies participated in our study. ANALYSIS AND DESIGN: Expert opinions were gathered through focus group discussions (FGDs). Thematic analysis was employed to analyse the findings and develop a model for designing a comprehensive, long-term health promotion programme using ATLAS.ti software. Additionally, a standardised framework was developed to represent the conceptual model of the twin HPPP. RESULTS: Eight FGDs were conducted, involving 16 experts. Thematic analysis identified eight themes and seven subthemes that encompassed the critical aspects of a continuous monitoring programme for twin health. Based on these identified themes, a conceptual framework was developed for the implementation of an HPPP tailored for twins. CONCLUSION: This study presented the initial endeavour to establish a comprehensive and practical solution in the form of a continuous HPPP designed to tackle the obstacles of twins' cohorts.

Pulmonary hydatid disease remains a global public health issue. Symptoms often result from cyst rupture, causing fever, cough, and hemoptysis. Radiographs may show homogeneous masses, air-fluid levels, or the pathognomonic "water lily" sign. Surgical removal is the primary treatment, with early diagnosis crucial to prevent acute hypersensitivity reactions and death.
RESUMEN
Insertion of a nasogastric tube (NGT) is generally considered safe; however, it is not without risk, and in cases of misplacement, complications and even death may occur. In this article, we reported a case of NGT misplacement in a 75-year-old male, which resulted in aspiration pneumonia. We also reviewed published cases of NGT misplacement. Clinicians should pay enough attention to the confirmation of the proper placement of an NGT. A systematic approach for NGT insertion and confirmation is required to prevent misplacement.
RESUMEN
Key Clinical Message: Common complications after PE surgery include ventricular tachycardia, cardiac arrest, pneumothorax, and bar displacement. These can lead to severe outcomes, emphasizing the need for caution and meticulous post-operative monitoring. Patients and their families should be well-informed about potential risks during the consent process. Abstract: The objective of this study was to raise awareness among medical staff and surgeons about potential complications, particularly rare and life-threatening ones, associated with pectus excavatum (PE) surgery. PE is the most common chest wall deformity, characterized by sternal depression. Patients primarily seek treatment for cosmetic concerns, but some also report exercise intolerance and shortness of breath. Although surgical repair is the standard treatment, the incidence and nature of severe complications remain unclear and underreported. This study presents a case of a lethal cardiac event following PE surgery and conducts a systematic review of published case reports. This study describes a case of a lethal complication of ventricular fibrillation and cardiac arrest following the Ravitch procedure for correction of PE in a 10-year-old boy. A systematic review of relevant cases of PE surgery complications was conducted. Of the 506 initial records retrieved, 93 case reports from 83 articles were identified over the 23 years. Among them, 72 patients were male, and 20 cases were female. The average age of patients was 19.2 ± 7.7 years (range: 5-53). Complications had occurred up to 37 years from the time of surgery, with most of the cases (22.5%) occurring during the operation. The most frequent complications included cardiothoracic issues and displacement of the implanted steel bar. In nine patients, complications led to fatal outcomes. Due to the possible risks of PE surgery, particularly in cosmetically motivated cases, surgeons must exercise extreme caution and remain vigilant for rare and potentially life-threatening complications.

RESUMEN
Background: Pharmacotherapy with biologics and small molecules, as the more effective therapies for moderate to severe ulcerative colitis (UC) and Crohn's disease (CD), is complex. Choosing the best methods for their utilization in order to induce and maintain remission are critical for practicing gastroenterologists. We aimed to develop an Iranian consensus on the management of inflammatory bowel disease (IBD) patients with biologics and small molecules. Methods: A Delphi consensus was undertaken by experts who performed a literature summary and voting process. Quality of evidence was assessed using the Grading and Recommendations Assessment, Development, and Evaluation; and an additional risk of bias-protocol. Results: Following an extensive search of the literature, 219 studies were used to determine the quality of the evidence. After three rounds of voting, consensus (defined as≥80% agreement) was reached for 87 statements. Conclusion: We considered different aspects of pharmacotherapy in this consensus. This guideline, along with clinical judgment, can be used to optimize management of IBD patients.
RESUMEN
Data suggest that coronavirus disease 2019 (COVID-19) results in a prothrombotic state leading to arterial and venous thromboses. Vaccination, novel antiviral drugs, and emerging variants have changed the course of the disease in many ways; however, their effects on the incidence of thrombotic events and the efficacy of preventative antithrombotic agents have not been yet evaluated. A systematic search was conducted to identify studies reported on the incidence of thrombotic events based on vaccination status, use of novel antiviral drugs, and emerging viral variants. Similarly, we screened the ongoing/published randomized trials of preventative antithrombotic therapy in any COVID-19 population to assess whether subgroup-specific results were reported based on any of these variants. Upon searching a total of 3,451 records, only one entry fulfilled the inclusion criteria of our systematic review, which was a self-controlled case series on 29,121,633 vaccinated individuals, the incidence rate ratio of thrombotic complication after breakthrough infection was 13.86 (95% confidence interval [CI]: 12.76-15.05) compared with 1.10 (95% CI: 1.02-1.18) during the 28-day postvaccination. In conclusion, although the mortality benefit of mass vaccination and the early promising results of the new antiviral therapies are well known, we were unable to find clinical evidence on whether vaccination, the use of novel antiviral agents, and emerging viral variants have affected the incidence rate of thrombotic events or impacted the efficacy of prophylactic antithrombotic therapy in patients with COVID-19. Analyses from existing trials and large-scale registries can provide interim knowledge and any findings of relevance should be incorporated in the design of future trials.

Background and Aim: The COVID-19 pandemic forced healthcare systems to apply new technology-based solutions. The main objective of our study was to describe the conceptual model for rapid implementation of telepharmacy service and the main steps that should be considered. Method: In response to a limited number of on-site clinical pharmacy specialists and a lack of technology infrastructure, a cross-sectional telepharmacy program was established to support major teaching hospitals. A store and forward model of teleconsultation was employed using WhatsApp messenger to cover various aspects of multidisciplinary collaboration in COVID-19 management. All identifiable personal information was removed from all exchanged messages of collaborative consultations. The thematic analysis of consultations was performed to extract the main themes and subthemes that should be considered for designing future telepharmacy systems. Results: Through telepharmacy service, 600 intensive care unit teleconsultations for COVID-19 cases were conducted in the residence center and nonresidence centers. In total, 1200 messages were exchanged between specialists in 3 months. The average time taken to respond to a message was 1.30 h. Thematic analysis revealed four main concepts and 15 subconcepts that should be considered in telepharmacy consultations for COVID-19 management. Based on the extracted themes, a conceptual model for developing a telepharmacy program was devised. Conclusion: The results showed that by utilizing telehealth, clinical pharmacists could cover critically ill patients who need pharmacotherapy counseling through interdisciplinary collaboration. Moreover, the main features of our service that are represented through this survey can be employed by other researchers for developing telepharmacy services.

RESUMEN
Pyoderma gangrenosum is a rare ulcerative dermatosis. It may be caused by some drugs, including small molecule tyrosine kinase inhibitors (TKIs). The aim of this study was to evaluate the reported evidence of pyoderma gangrenosum associated with the use of these drugs. A systematic electronic literature search of PubMed and Embase was conducted. In these databases, search terms describing pyoderma gangrenosum were combined with TKIs. Fifteen case reports (eight cases associated with sunitinib, two with imatinib, two with ibrutinib, one with gefitinib, one with pazopanib, and one with dabrafenib and trametinib) were identified over the 14 years. The average Naranjo score of these cases is 6.6, which indicates a probable adverse drug reaction. Pyoderma gangrenosum is a probable and reversible drug reaction associated with some TKIs. Detailed medical history can help to prompt diagnosis of drug-induced pyoderma gangrenosum. Clinicians should be aware of TKI-associated pyoderma gangrenosum when caring for the skin of oncologic patients undergoing therapy with kinase inhibitors.

PURPOSE OF REVIEW: Although vitamin C is essentially a nontoxic vitamin; however, it is important to be aware regarding the safety of high doses before the wide clinical use. RECENT FINDINGS: Minor side effects of vitamin C have been reported, many being reported in earlier studies. High doses of vitamin C (up to 1.5âg/kg three times a week as intravenously) were safe in cancer patients with normal renal function and perfect glucose-6-phosphate dehydrogenase activity. As the dose and duration of administration of vitamin C in sepsis are lower and shorter than those used in cancer patients, it seems that it is relatively safe for this population. In ongoing trials, safety of high doses of vitamin C is considered. SUMMARY: Data regarding the safety of high doses of vitamin C are scant. Until more data become available, caution should be applied in the use of high doses of vitamin C in patients with hemochromatosis, glucose-6-phosphate dehydrogenase deficiency, renal dysfunction, kidney stone, oxaluria, and pediatrics.

BACKGROUND: In recent years, few cases of post-artemisinin delayed hemolysis have been reported. OBJECTIVE: All cases of post-artemisinin delayed hemolysis were reported from non-middle east areas. No case of post-artemisinin delayed hemolysis has yet been reported from this region. In this paper, we describe a case of post-artemisinin delayed hemolysis in an Iranian female. Moreover, previous reports have been reviewed. METHODS: Patient's data including demographic characteristics, past medical, drug and travelling history, present illness, vital signs, laboratory data, clinical course of current illness and follow-up findings were considered. RESULTS: A 27-year-old female with a recent travel history to Ghana admitted with severe falciparum malaria. She was successfully treated with parenteral artesunate. However after 12 days of post artesunate treatment, she returned with dark urine, malaise and fatigue. CONCLUSION: Considering the clinical course and base on a reliable causality assessment scale, post artesunate delay hemolytic anemia was possible.
