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. Fungi, such as Candida, have also been reported as causative organisms. Citrobacter and Enterococci have also been found to cause emphysematous cystitis. Although it is a rare type of bladder infection, it is the most common type of all gas-forming bladder infections. The condition is characterized by the formation of air bubbles in and around the bladder wall. The gas found in the bladder consists of nitrogen, hydrogen, oxygen, and carbon dioxide. The disease most commonly affects elderly diabetic and immunocompromised patients. The first case was identified in a post-mortem examination in 1888. Signs and symptoms
Signs and symptoms of emphysematous cystitis include air in the bladder wall, altered mental status, severe abdominal pain, weakness, dark urine, dysuria, fever, lethargy, vomiting, as well as white blood cells and bacteria in the urine. Where some patients may be asymptomatic, others may present with septic shock. Symptoms can vary greatly from patient to patient, which makes the disease difficult to diagnose. In some cases of emphysematous cystitis, patients do not even claim to have any urinary symptoms. Urinary symptoms can include blood in the urine, increased urinary frequency, urgency, occasional incontinence, difficulty voiding, and burning sensation. Emphysematous cystitis is often indicated in patients who have air in the urine. In some cases, emphysematous cystitis can cause thickening of the bladder wall.
Achilles tendinitis, also known as achilles tendinopathy, occurs when the Achilles tendon, found at the back of the ankle, becomes sore. Achilles tendinopathy is accompanied by alterations in the tendons structure and mechanical properties. The most common symptoms are pain and swelling around the affected tendon. The pain is typically worse at the start of exercise and decreases thereafter. Stiffness of the ankle may also be present. Onset is generally gradual.It commonly occurs as a result of overuse such as running. Other risk factors include trauma, a lifestyle that includes little exercise, high-heel shoes, rheumatoid arthritis, and medications of the fluoroquinolone or steroid class. Diagnosis is generally based on symptoms and examination.There are several simple actions that individuals can take to prevent or reduce tendinitis. Though commonly used, some of these actions have limited or no scientific evidence to support them, namely pre-exercise stretching. Strengthening calf muscles, avoiding over-training, and selecting more appropriate footwear are more well-regarded options. Running mechanics can be improved with simple exercises that will help runners avoid achilles injury. Treatment typically involves rest, ice, non-steroidal antiinflammatory agents (NSAIDs), and physical therapy. In those whose symptoms last more than six months despite other treatments, surgery may be considered. Achilles tendinitis is relatively common. Signs and symptoms
Symptoms can vary from an ache or pain and swelling to the local area of the ankles, or a burning that surrounds the whole joint.
