If AKI develops after major abdominal surgery (13.4% of all people who have undergone major abdominal surgery) the risk of death is markedly increased (over 12-fold). Kidney function
Depending on the cause, a proportion of patients (5–10%) will never regain full kidney function, thus entering end-stage kidney failure and requiring lifelong dialysis or a kidney transplant. Patients with AKI are more likely to die prematurely after being discharged from hospital, even if their kidney function has recovered.The risk of developing chronic kidney disease is increased (8.8-fold). Epidemiology
New cases of AKI are unusual but not rare, affecting approximately 0.1% of the UK population per year (2000 ppm/year), 20x incidence of new ESKD (end-stage kidney disease). AKI requiring dialysis (10% of these) is rare (200 ppm/year), 2x incidence of new ESKD.There is an increased incidence of AKI in agricultural workers because of occupational hazards such as dehydration and heat illness. No other traditional risk factors, including age, BMI, diabetes, or hypertension, were associated with incident AKI. Acute kidney injury is common among hospitalized patients. It affects some 3–7% of patients admitted to the hospital and approximately 25–30% of patients in the intensive care unit.Acute kidney injury was one of the most expensive conditions seen in U.S. hospitals in 2011, with an aggregated cost of nearly $4.7 billion for approximately 498,000 hospital stays. This was a 346% increase in hospitalizations from 1997, when there were 98,000 acute kidney injury stays.
Acne miliaris necrotica is a rare condition consisting of follicular vesicopustules, sometimes occurring as solitary lesions that are usually very itchy. The condition affects middle aged and elderly individuals. Affected areas can include the scalp, frontal hairline, face, and chest. Causes
It has been hypothesized that the body overreacts to an organism such as the S. aureus bacterium. Diagnosis
Treatment
There are multiple medications that are able to treat acne varioliformis. Topical
Clindamycin 1% lotion or Benzoyl peroxide/clindamycin gel
Erythromycin 2% gel
1% hydrocortisone cream

Systemic
Doxycycline 50 mg twice daily
