A solitary bronchial papilloma with unusual endoscopic presentation: case study and literature review

<p>Abstract</p> <p>Background</p> <p>Solitary endobronchial papillomas (SEP) are rare tumors and most of them are described by case report. A misdiagnosis is common with viral related papillomas. A histopathological classification has recently permitted a major advancement in the understanding of the disease.</p> <p>Case Presentation</p> <p>We report a case of a mixed bronchial papilloma with an unusual endoscopic presentation. The literature was extensively reviewed to ascertain the unusual characteristics of the current case. A 39-year of age male was referred to our institution for the investigation of a slight hemoptysis. Routine examination was normal. A fibroscopy revealed an unusual feature of the right main bronchus. The lesion was a plane, non-bleeding, non-glistering sub-mucosal proliferation. No enhanced coloration was noticed. Biopsies revealed a mixed solitary bronchial papilloma. In situ HPV hybridization was negative. Endoscopic treatment (electrocautery) was effective with no relapse.</p> <p>Conclusion</p> <p>This lesion contrasts with the data of the literature where papilloma were described as wart-like lesions or cauliflower tumors, with symptoms generally related to bronchial obstruction. We advise chest physicians to be cautious with unusually small swollen lesions of the bronchi that may reveal a solitary bronchial papilloma. Endoscopic imaging can significantly contribute to the difficult diagnosis of SEP by pulmonary physicians and endoscopists.</p

Airway and Esophageal Stenting in Patients with Advanced Esophageal Cancer and Pulmonary Involvement

BACKGROUND: Most inoperable patients with esophageal-advanced cancer (EGC) have a poor prognosis. Esophageal stenting, as part of a palliative therapy management has dramatically improved the quality of live of EGC patients. Airway stenting is generally proposed in case of esophageal stent complication, with a high failure rate. The study was conducted to assess the efficacy and safety of scheduled and non-scheduled airway stenting in case of indicated esophageal stenting for EGC. METHODS AND FINDINGS: The study is an observational study conducted in pulmonary and gastroenterology endoscopy units. Consecutive patients with EGC were referred to endoscopy units. We analyzed the outcome of airway stenting in patients with esophageal stent indication admitted in emergency or with a scheduled intervention. Forty-four patients (58+/-\-8 years of age) with esophageal stenting indication were investigated. Seven patients (group 1) were admitted in emergency due to esophageal stent complication in the airway (4 fistulas, 3 cases with malignant infiltration and compression). Airway stenting failed for 5 patients. Thirty-seven remaining patients had a scheduled stenting procedure (group 2): stent was inserted for 13 patients with tracheal or bronchial malignant infiltration, 12 patients with fistulas, and 12 patients with airway extrinsic compression (preventive indication). Stenting the airway was well tolerated. Life-threatening complications were related to group 1. Overall mean survival was 26+/-10 weeks and was significantly shorter in group 1 (6+/-7.6 weeks) than in group 2 (28+/-11 weeks), p<0.001). Scheduled double stenting significantly improved symptoms (95% at day 7) with a low complication rate (13%), and achieved a specific cancer treatment (84%) in most cases. CONCLUSION: Stenting the airway should always be considered in case of esophageal stent indication. A multidisciplinary approach with initial airway evaluation improved prognosis and decreased airways complications related to esophageal stent. Emergency procedures were rarely efficient in our experience

Persistent Arthralgia Associated with Chikungunya Virus: A Study of 88 Adult Patients on Reunion Island

International audienceBackground: An outbreak of chikungunya virus infection occurred on Reunion Island during the period 2005-2006. Persistent arthralgia after chikungunya virus infection has been reported, but few studies have treated this aspect of the disease.Methods: Adult patients with laboratory-confirmed acute chikungunya virus infection who were referred to Groupe Hospitalier Sud Reunion during the period 2005-2006 were asked to participate in the study. Patients were assessed a mean of 18 months after acute disease occurred. Assessment consisted of answering questions on a standard form, undergoing a medical examination, and being tested for the presence of IgM antibodies to chikungunya virus.Results: Eighty-eight patients (mean age, 58.3 years; male-to-female ratio, 1.1:1.0) were included in this study. Fifty-eight patients (65.9%) had been hospitalized for acute chikungunya virus infection, and a history of arthralgia before chikungunya virus infection was reported by 39 patients (44%). Fifty-six patients (63.6%) reported persistent arthralgia related to chikungunya virus infection, and in almost one-half of the patients, the joint pain had a negative impact on everyday activities. Arthralgia was polyarticular in all cases, and pain was continuous in 31 patients (55.4%). Overall, 35 patients (39.7%) had test results positive for IgM antibodies to chikungunya virus.Conclusions: Persistent and disabling arthralgia was a frequent concern in this cohort of patients who had experienced severe chikungunya virus infection approximately 18 months earlier. Further studies are needed to evaluate the prevalence of persistent arthralgia in the general population to determine the real burden of the disease

Double stenting in a patient with a voluminous esophageal tumor.

<p>Initial staging fibroscopy showed extrinsic compression with no fistula and/or malignant proliferation in the trachea. Esophageal stenting was required because of complete dysphagia. Double stenting was performed before palliative radiotherapy. No complications occurred.</p

Perforation of the trachea by an esophageal stent.

<p>The carina and the main left bronchus were severely injured. The initial fibroscopy performed before esophageal stenting, showed a slight intrinsic compression of the lower part of the trachea and main left bronchus.</p
