Ergonomics of bronchoscopy: good advice or a pain in the neck?

Interventional pulmonologists require a unique set of skills including precise motor abilities and physical endurance, but surprisingly the application of ergonomic principles in the field of bronchoscopy remains limited. This is particularly intriguing when considering the significant impact that poor ergonomics can have on diagnostic aptitude, income potential and overall health. It is therefore imperative to provide comprehensive education to physicians regarding the significance of ergonomics in their work, especially considering the introduction of advanced diagnostic and therapeutic procedures. By implementing simple yet effective measures (e.g. maintaining neutral positions of the wrist, neck and shoulder; adjusting the height of tables and monitors; incorporating scheduled breaks; and engaging in regular exercises), the risk of injuries can be substantially reduced. Moreover, objective tools are readily available to assess ergonomic postures and estimate the likelihood of work-related musculoskeletal injuries. This review aims to evaluate the current literature on the impact of procedure-related musculoskeletal pain on practising pulmonologists and identify modifiable factors for future research.

Airway Injury Caused by Aspiration of Iron Sulfate Pills: A Series of 11 Cases.

It is not widely recognized that iron (ferrous sulfate) pill aspiration causes airway damage. Clinical diagnosis is challenging because patients are often unaware that they have aspirated a pill. The literature on this entity consists mainly of case reports. The aim of this study is to describe the clinical and pathologic features of iron pill aspiration in a series of 11 patients. A retrospective review of our pathology archives was performed to identify cases of iron pill aspiration (2013-2023). All available histologic and cytologic material was rereviewed. Clinical information was collected from the electronic medical record, and imaging studies were rereviewed. Eighteen endobronchial biopsies were identified from 11 patients (7 women and 4 men; mean age, 70 years; range, 44-82 years). Eight patients had corresponding cytology (20 specimens). Medication history was available in 9 of 11 patients, all of whom were taking iron sulfate pills. Two patients reported possible aspiration episodes; 4 had risk factors for aspiration. The diagnosis of iron pill aspiration was suspected prior to biopsy in only 1 case. Histologically, iron pill particles were yellow, golden brown, or gray, were elongated and crystal or fiber like, and stained strongly with an iron stain. Common histologic findings included mucosal ulceration, acute and/or chronic inflammation, fibrosis, and squamous metaplasia. Iron pill particles were also identified in 11 cytology specimens from 6 patients. On Papanicolaou staining, iron pill particles were yellow to golden, fiber like, refractile, and crystalline. Reactive epithelial cells, squamous metaplasia, and acute inflammation were common. The combination of iron pill intake and discolored mucosa on bronchoscopy is a potential clue to the diagnosis of iron pill aspiration. Pathologists should familiarize themselves with the appearance of iron pill particles in endobronchial biopsies and cytology specimens from the respiratory tract as this diagnosis is seldom suspected on clinical grounds, and most patients lack a history of aspiration.

Giant Cell Interstitial Pneumonia In Native, Transplanted And Re-Transplanted Lungs 8 Years Apart Without Known Hard Metal Exposure.

Pneumoconioses are a group of non-neoplastic pulmonary disorders caused by inhaled inorganic particles. Well-described pneumoconioses include asbestosis, silicosis, coal worker's pneumoconiosis, chronic beryllium disease, and hard metal lung disease. Giant cell interstitial pneumonia (GIP) is a distinctive and rare pneumoconiosis most frequently found in workers exposed to hard metals, primarily cobalt and tungsten carbide. The pathologic picture is considered virtually pathognomonic for hard metal lung disease, although this dogma has been questioned by a few reports of giant cell interstitial pneumonia in patients without apparent hard metal exposure. Giant cell interstitial pneumonia is even rarer in lung transplant recipients. Here, we present a patient without known hard metal exposure who was found to have persistent giant cell interstitial pneumonia in native, transplanted and re-transplanted lungs 8 years apart.

Recycling plastic: diagnosis and management of plastic bronchitis among adults.

Plastic bronchitis is a rare, underdiagnosed and potentially fatal condition. It is characterised by the formation and expectoration of branching gelatinous plugs that assume the shape of the airways. These airway plugs differ from the allergic mucin that characterises allergic bronchopulmonary aspergillosis and mucoid impaction of the bronchi. Plastic bronchitis is most often encountered in the paediatric population following corrective cardiac surgery, such as the Fontan procedure. It also occurs in adults. Plastic bronchitis in adults is rare, heterogeneous in its aetiology, and can lead to respiratory distress or even life-threatening airway obstruction. Plastic bronchitis in adulthood should not be overlooked, particularly in patients with chronic inflammatory lung diseases. This review presents current understanding of the presentation, aetiology, pathogenesis, pathology and management of plastic bronchitis in adults.

Rare cause of large anterior mediastinal mass--Thymolipoma.

BACKGROUND: Among the diverse causes of anterior mediastinal masses, thymolipoma is not a common entity. It largely comprises of adipose tissue and remnants of thymus tissue. Most patients are asymptomatic and are diagnosed incidentally. CASE SUMMARY: Sixty-six-year-old female presented to the Emergency Department with a week of worsening shortness of breath, palpitations, diarrhea, palpitations & over 30 kg of unintentional weight loss in the last 1 year. Her investigations were in line of thyrotoxicosis with other lab findings correlating to the disease. However, during investigations, a chest radiograph showed left lower zone opacity and on follow-up CT scan it was revealed to be a huge fatty mass comprising of soft tissues arising from the anterior mediastinum, pushing the left diaphragm inferiorly and the lower lobe of left lung was entirely collapsed. CONCLUSION: Thymolipoma can occur as a single entity and patients are often clinically asymptomatic. Biopsy is the definitive diagnostic tool, but it can also be challenging, especially if adequate samples are not obtained. CT scan can play an important role in supporting the diagnosis, with findings of fat containing structure arising from the anterior mediastinum along with internal fat stranding & nodularity. Treatment is surgical with excision of the entire mass.
