Pyelonephritis condition that occurs in both males and females of all refers to a urinary tract infection involving the kidney. The prevalence and incidence of urinary tract This may be an acute or chronic process. Acute infection is higher in women than in men, which is pyelonephritis is characterized by fever, chills, and likely the result of several clinical factors including fank pain. Patients may also experience nausea and anatomic differences, hormonal effects, and behavior vomiting, depending on the severity of the infection patterns. Chronic pyelonephritis implies pathogenic invasion of the urinary tract, which leads recurrent renal infections and may be associated to an infammatory response of the urothelium. Urethritis refers Bacteriuria refers to the presence of bacteria to an infammation or infection of the urethra. Isolated bacterial urethritis is associated signs and symptoms that result from rare in women. Bacteriuria may be to sexually transmitted organisms, may also cause asymptomatic, particularly in elderly adults. Host factors such incontinence, cystocele, and elevated volumes of post- as changes in normal vaginal fora may also affect the void residual urine. Other common most commonly diagnosed in children, but it may organisms include Enterococcus faecalis, Klebsiella also be identifed in adults. Common examples include tend to occur more often in immunosuppressed urinary calculi and indwelling catheters. Fungal urinary catheters are associated with chronic bacterial infections with Candida spp are the most common colonization, which occurs in almost all patients after nonbacterial infections. The overall modifcations with antibiotic and silver impregnation role of anaerobic urinary infections is controversial; have been developed in an effort to decrease the rate however, anaerobes may be especially dangerous in of infection in patients with indwelling catheters (2). This acidity is critical to Research on the physiology and microbiology permit the growth of Lactobacillus in the normal of urinary tract infections has identifed a number 154 155 Urologic Diseases in America Urinary Tract Infection in Women Table 1. A as pili, fmbriae, and chemical adhesins that increase urinalysis that reveals both bacteriuria and pyuria is their ability to adhere to host tissues.

The increased prevalence of drug- 53,067 cases per 100,000 adult women, based on the resistant bacteria has made susceptibility testing National Health and Nutrition Examination Survey particularly important. Self-reported incidence of physician-diagnosed urinary tract infection during the previous 12 months by age and history of urinary tract infection among 2000 United States women participating in a random digit dialing survey. The average standard error for the total incidences in each of the age groups is 2. Urinary tract infections may be associated with The need for urine culture is also an area of debate.

These using more-expensive antimicrobials such as medications cost less than newer antimicrobials fuoroquinolones as initial therapy. In addition, reserving be due in part to increased rates of outpatient care fuoroquinolones and broad-spectrum antimicrobials and increased availability and marketing of these for complicated infections or cases with documented products. However, it has the potential to increase resistance to frst-line therapy may help reduce the both overall costs and antimicrobial resistance.

Table 10 compares the lye and no-lye relaxers in terms of their effect on the hair shaft. These are the same thioglycolate chemicals that were described as permanent wave solutions, except that they are formulated as thick creams, rather than lotions. Also, instead of the hair being wound on mandrels, it is combed straight while the thioglycolate cream is in contact with the hair shaft. Thioglycolate hair straighteners are extremely harsh on the hair and are the least popular of all the relaxing chemicals for this reason. Gently comb hair straight for 10 30 minutes until degree of relaxation is achieved. Chemical burns can also occur with this variety of chemical hair straightener (71). The least damaging of all hair-straightening chemicals are the ammonium bisulte creams. These products contain a mixture of bisulte and sulte in varying ratios depending on the pH of the lotion. Many of the home chemical straightening products are of this type, but can only produce short-lived straightening. These are very similar to the home sulte perma- nent waves previously discussed, except the hair is combed straight instead of being wound on curling rods. The key to successful hair relaxing is an experienced beautician who can quickly apply and remove the chemicals and determine when the desired degree of disulde bond breaking has occurred. It is estimated that virgin hair loses about 30% of its tensile strength following a properly performed chemical straightening procedure. It also becomes more porous, allowing future relaxing procedures to process more quickly (72). Hair relaxing is a careful balance between achieving the straighten- ing of kinky hair and minimizing irreversible hair-shaft damage. With continued grooming and chemical manipulation the hair loses it protective lipid coating, cuticular scale, elasticity, and strength. Combing, brushing, and shampooing all inict damage on the hair shaft that is temporarily partially reversed with conditioners. Semipermanent and permanent dyeing proce- dures involve the formation of holes within the hair shaft where the color molecules can either penetrate or undergo chemical formation. Once these holes are created through cuticle swelling, they can never be completely closed. An even more dramatic physical insult is inicted with permanent waving and straightening. Here the strong protein backbone of the hair shaft is broken by dissolving and reforming the disulde bonds. Hair with an altered physical shape can never be returned to its original conguration. Individuals with hair and scalp disease, with or without hair loss, will want to beautify their hair with some of the procedures discussed in this chapter. While the physician may be tempted to tell patients to avoid all hair products and procedures except for the most basic shampoos, it is unlikely that this advice will be heeded. Thus, a basic working knowledge of the formulation and function of these products must be obtained.

The bloodstream of infected patients con- tains not only fully competent viral particles, but an even higher abundance of defective viral particles that form small spheres and laments. These latter forms are noninfectious and are composed of HbsAg and host membrane lipid.
