Bacterial infections spontaneous

Onychomycosis is a chronic infection that rarely remits spontaneously. Adequate treatment is essential to prevent spread to other sites, secondary bacterial infections, cellulitis, or gangrene. Due to the chronic nature and impenetrability of nails, topical agents have low efficacy rates for treating onychomycosis. Oral agents that can penetrate the nail matrix and nail base, such as itraconazole and terbinafine, are more effective than ciclopirox lacquer. Itraconazole and terbinafine demonstrate mycological cure rates of 62%37 and 76%,38 respectively, while ciclopirox has a cure rate of 29% to 36%.39...

These symptoms may subside spontaneously at the age of 3 or 4, or at puberty. Expression may be intensified, or the affected site may change. The exacerbation of disease can be caused by accompanying viral or bacterial infections and expansion of the panel of allergens leading to polysensibilization (Bohme et al., 2002). 

Spontaneous bacterial peritonitis (SBP) (H.O. Conn, 1964, 1971) is the term used to describe bacterially infected ascitic fluid in liver cirrhosis where the exact source of infection or path of infection is not known. 

Most antibiotics fight bacterial infections by interfering with some aspect of protein synthesis in the bacteria. We are most interested in those antibiotics that are specific for bacteria with minimal effect on animal protein synthesis. Table 21-3 lists some of the common antibiotics used in medicine. Large-scale use of antibiotics has been highly successful but some bacteria have fought back by spontaneous mutation and propagation of antibiotic-resistant strains. This requires that we keep ahead of the bacteria by synthesizing new antibiotics to kill the mutant strains. 

In some clinical conditions, such as acute bacterial or viral infections, spontaneous DNA synthesis (without the presence of drug) is so high that the stimulatory effect of the added drug is negligible... 

Peritonitis may be classified as primary, secondary, or tertiary. Primary peritonitis, also called spontaneous bacterial peritonitis, is an infection of the peritoneal cavity without an evident source of bacteria from the abdomen.1,2 In secondary peritonitis, a focal disease process is evident within the abdomen. Secondary peritonitis may involve perforation of the gastrointestinal (GI) tract (possibly because of ulceration, ischemia, or obstruction), postoperative peritonitis, or posttraumatic peritonitis (e.g., blunt or penetrating trauma). Tertiary peritonitis occurs in critically ill patients and is infection that persists or recurs at least 48 hours after apparently adequate management of primary or secondary peritonitis.

Another complex macromolecular aggregate that can reassemble from its components is the bacterial ribosome. These ribosomes are composed of 55 different proteins and by 3 different RNA molecules, and if the individual components are incubated under appropriate conditions in a test tube, they spontaneously form the original structure (Alberts et al., 1989). It is also known that even certain viruses, e.g., tobacco mosaic virus, can reassemble from the components this virus consists of a single RNA molecule contained in a protein coat composed by an array of identical protein subunits. Infective virus particles can self-assemble in a test tube from the purified components. 

Mild cases, characterised by pinkness or infection of the eardrum, often resolve spontaneously and need only analgesia emd observation. They are normally viral. A bulging, inflamed eardrum indicates bacterial otitis media usually due to Streptococcus pneumoniae, Haemophilus influenzae, Moraxella (Bran-hamella) catarrhalis. Streptococcus pyogenes (Group A) or Staphylococcus aureus. Amoxicillin or co-amoxiclav is satisfactory, but the clinical benefit of antibiotic therapy is very small when tested in controlled trials. Chemotherapy has not removed the need for myringotomy when pain is very severe, and also for later cases, as sterilised pus may not be completely absorbed and may leave adhesions that impair hearing. Chronic infection presents a similar problem to that of chronic sinus infection, above.

Complications such as variceal bleeding, hepatic encephalopathy, ascites and infections as well as reduced renal function also influence the mortality rate of liver cirrhosis (in Germany some 25,000/year). The main causes of death are hepatic coma or liver failure (25-40%), bleeding (20-30%), infections (about 10%) and HCC (about 5%). Spontaneous bacterial peritonitis is fatal in 50-70%, and with liver dysfunction even in 90% of cases. Occurrence of the hepatorenal syndrome is almost invariably fatal.
