Emphysematous cystitis is a rare type of infection of the bladder wall by gas-forming bacteria or fungi. The most frequent offending organism is E. coli . Other gram negative bacteria, including Klebsiella and Proteus are also commonly isolated.
Low magnification micrograph of pneumatosis intestinalis in bowel wall.. Pneumoperitoneum (or peritoneal emphysema), air or gas in the abdominal cavity.The most common cause is a perforated abdominal viscus, generally a perforated peptic ulcer, although any part of the bowel may perforate from a benign ulcer, tumor or abdominal trauma.
A gas-producing UTI (emphysematous cystitis: rare). Emphysematous pyelonephritis. Male scuba divers utilizing condom catheters or female divers using a She-p external catching device for their dry suits are also susceptible to pneumaturia. [1]
The gloved finger sign is a radiologic sign observed on chest radiographs or CT scans that indicates the presence of mucoid impaction in the lungs. Mucoid impaction occurs when bronchi become dilated and filled with mucus.
Low-dose high-resolution (1.25 mm) chest CT. HRCT is performed using a conventional CT scanner. However, imaging parameters are chosen so as to maximize spatial resolution: [1] a narrow slice width is used (usually 1–2 mm), a high spatial resolution image reconstruction algorithm is used, field of view is minimized, so as to minimize the size of each pixel, and other scan factors (e.g. focal ...
In the vast majority of cases, this inflammation is brought on by infection, meaning most cases of cystitis are actually a type of lower urinary tract infection. This video discusses the pathophysiology, risk factors, signs and symptoms, treatment, and prevention of cystitis and lower urinary tract infection.
Most commonly emphysema refers to the permanent enlargement of air spaces in the lungs, [5] [6] and is also known as pulmonary emphysema. Emphysema is a lower respiratory tract disease, [ 7 ] characterised by enlarged air-filled spaces in the lungs , that can vary in size and may be very large.
Subcutaneous emphysema is also considered a hallmark of Fournier gangrene. [26] Symptoms of subcutaneous emphysema can result when infectious organisms produce gas by fermentation. When emphysema occurs due to infection, signs that the infection is systemic (i.e. that it has spread beyond the initial location) are also present. [9] [21]
