Air trapping in small airway diseases: A review of imaging technique and findings with an overview of small airway diseases.

Air trapping is a common finding radiologists encounter on CT imaging of the thorax. This term is used when there are geographic areas of differing attenuation within the lung parenchyma. Most commonly, this is the result of abnormal retention of air due to complete or partial airway obstruction from small airway pathologies.

Discordance between clinical and pathologic staging and the timeliness of care of non-small cell lung cancer patients diagnosed with operable tumors.

Aim: This study was performed to evaluate concordance between clinical and pathologic staging of non-small cell lung cancer (NSCLC) in our hospital network.

Methods: We retrospectively reviewed records of 417 patients with NSCLC who received curative surgery and whose pathology was evaluated in our hospital between 2016 and 2021. Cytology, tissue pathology, and associated clinical, surgical, and imaging information were retrieved from hospital digital records.

Post-Myocardial Infarction Ventricular Septal Defect Successfully Treated with Impella as Bridge to Cardiac Transplantation.

A 63-year-old female presented late with anterior ST-elevation myocardial infarction and cardiogenic shock. This was complicated by acute ventricular septal defect with large left-to-right shunt. An Impella CP was inserted on day seven with rapid haemodynamic improvement.

Lack of correlation between MSH3 immunohistochemistry and microsatellite analysis for the detection of elevated microsatellite alterations at selected tetranucleotide repeats (EMAST) in colorectal cancers.

Immunohistochemical evaluation of mismatch repair protein (MMR) expression is an important screening tool in diagnostic pathology, where it is routinely used to identify subsets of colorectal cancers (CRCs) with either inherited or sporadic forms of microsatellite instability (MSI). MSH3 is not included in current MMR panels, although aberrant MSH3 expression is reported to occur in 40-60% of CRCs and is associated with elevated microsatellite alterations at selected tetranucleotide repeats (EMAST) and a worse prognosis. In this study, we applied MSH3 immunohistochemistry and tetranucleotide MSI analysis to a cohort of 250 unselected CRCs to evaluate the potential use of the methods in routine practice.

Carcinoid tumours of the appendix: an analysis of emergency appendicectomies over a 24-year period and outcomes of laparoscopic versus open resection.

Background: Carcinoid tumours of the appendix are the most common primary malignant lesion of the appendix. However, the overall incidence remains low; found in as few as 0.3-0.

Typical and atypical carcinoid tumors of the lung: a clinicopathological correlation of 783 cases with emphasis on histological features.

We present 783 surgical resections of typical and atypical carcinoid tumors of the lung identified in the pathology files of 20 different pathology departments. All cases were critically reviewed for clinical and pathological features and further correlated with clinical outcomes. Long-term follow-up was obtained in all the patients and statistically analyzed to determine significance of the different parameters evaluated.

Benign epithelioid peripheral nerve sheath tumour arising in the rectum: A cytological and histological description.

A 57-year old man presented with a 3.6 cm submucosal rectal cystic mass detected on colonoscopy and MRI. The lesion was deroofed, with rectal cyst fluid and cyst wall received for examination.

Large air-filled intrapulmonary bronchogenic cyst associated with tension pneumothorax during air travel.

A 38-year-old woman developed a spontaneous right-sided tension pneumothorax during light aircraft travel. The aircraft was diverted to a regional centre, where emergent needle thoracostomy and chest tube insertion were performed. History suggested that this was the second episode of pneumothorax, with an untreated event with similar symptomatology during air travel 1 year ago.

Thymoma: a clinicopathological correlation of 1470 cases.

We present 1470 surgical resections for thymoma identified in the pathology files of 14 institutions from 11 countries with the purpose of determining and correlating a simplified histological classification of thymoma and pathological staging with clinical outcome. The study population was composed of 720 men and 750 women between the ages of 12 and 86 years (average, 54.8 years).
