Case presentation

We present a case series that describes three children (8-year-old white girl, 2-year-old white boy and 14-month-old Chinese boy) who presented with varied onset of allergic reactions to amoxicillin, specifically immediate (within the first hour after exposure) and non-immediate onset. One child developed immediate onset allergy to oral challenge with amoxicillin although his clinical history was evident for non-immediate onset allergy to amoxicillin. augmentin for sale He was the only case that had a positive skin test to penicillin. Two other children presented with reactions toward the end of their treatment course of amoxicillin, yet one patient developed immediate onset allergy while the other patient developed non-immediate onset allergy after challenge.

Yeast Infection vs. Urinary Tract Infection (UTI)

Candida albicans typically causes vaginal yeast infections. Bacterial infections typically cause urinary tract infections (UTIs). Thick white cottage-cheese like vaginal discharge characterizes vaginal yeast infections. Painful, frequent urination characterize urinary tract infections. Antifungal medications treat yeast infections while prescription antibiotics treat UTIs.

Oral Cephalosporins

Structurally, the cephalosporins have a beta-lactam ring (which they share with all penicillins) and a thiazolidine ring. These drugs are divided into generations based on their spectrum of antimicrobial activity.

Although the cephalosporins are often thought of as new and improved derivatives of the penicillins, they were actually discovered as naturally occurring substances separate from the penicillins. Brotzu noted the periodic clearing of microorganisms from sea water near a sewage outlet and isolated a substance with antibacterial properties that was produced by the fungus Cephalosporium acremonium .1 After further study and modification of this substance, the first commercially available cephalosporin (cephalothin) was introduced in 1962.

The effectiveness of an individual cephalosporin depends on its ability to overcome the mechanisms of resistance that bacteria have developed to combat beta-lactam antibiotics. A comparison of cephalosporins and penicillin, using penicillin V as the prototype, is presented in Table 2 .1 , 5 , 6 , 9 – 11 Selected differences among the oral agents in each cephalosporin generation are given in Table 3 .1 , 5 , 6 , 9 – 11
