Subglottic cysts are associated with prematurity and periods of early neonatal intubation and are a rare cause of infant stridor. In this study we analyse our experience of this rare but important problem. We discuss the aetiology, diagnosis and management of subglottic cysts. We carried out a retrospective review of all cases of subglottic cysts presenting to the otorhinolaryngology department at the Leeds teaching hospitals trust during the period between 1995 and 2005. In total seven patients were identified. A retrospective review of the case notes of all patients proven to have subglottic cysts at direct laryngoscopy and bronchoscopy was undertaken. Seven patients were identified, four males and three females. Five were born premature (24-31 weeks). All were intubated with average intubation period of 20.6 days. Six of our patients' underwent endoscopic marsupialisation using cup forceps and one with a contact diode laser. Two patients had recurrence of the cyst and had a repeat of endoscopic marsupialisation. This study highlights the associated risk of neonatal intubation with the risk of formation of subglottic cysts, and the need for early diagnosis and appropriate treatment to avoid unnecessary morbidity.
BACKGROUND: The transition from medical resident to subspecialty fellow is a critical time period in fellowship training that has not been well described. The current practices of fellow orientation in pulmonary and critical care training programs are not known. OBJECTIVES: The aim of this study was to describe orientation practices for training programs in the United States. METHODS: A 10-question survey was sent via e-mail to program directors of pulmonary/critical care fellowship programs identified on the American Thoracic Society (ATS) web-page of current programs. RESULTS: Eighty-seven programs responded (61.7%), of which 86% had a formal orientation program. The mean time spent in fellow orientation was 5-10 h in didactic sessions and 0-5 h in wet labs. The most frequent didactic sessions were bronchoscopy in 69 programs (80.2%), pulmonary function testing in 63 programs (73.3%) and orientation to hospital services in 63 programs (73.3%). The most frequent use of wet labs was in bronchoscopy training in 60 programs (81.1%) and ventilators in 45 programs (60.8%). Simulators were used in 37 programs (43%). The majority reported that these areas were covered with on the job training, without a formal designated orientation. CONCLUSION: This survey demonstrated that early fellow training differs across programs in both time spent and clinical and procedural topics covered. An early, standardized approach to clinical and procedural training can assure appropriate exposure that cannot be guaranteed by on the job training. To provide justification for such an approach, clinical outcomes need to be correlated with training methods.
Despite of the clinical studies proving the benefits of lung volume reduction surgery and determining the indications and candidates, the surgical intervention has not penetrated into the standard treatment of emphysema. Perioperative mortality is relatively high at patients with end-stage emphysema, therefore a less invasive procedure might be most useful in medical practice. Bronchoscopic lung volume reduction is a technically simple procedure including insertion of a bronchial blocker (plug) or an endobronchial valve, either totally blocking the air flow, or blocking it only during the inspiration. However, there are only few clinical data available concerning of surgical and bronchial interventions. A multinational clinical study is in progress in three Hungarian pulmonological centers implanting endobronchial plugs into the subsegmental bronchi of patients with severe emphysema.
