Tonsillitis

Early signs and symptoms of necrotizing fasciitis include fever, severe pain, swelling, and erythema (redness) at the wound site or site where GAS organisms entered the body. The pain and swelling may extend well beyond the erythema. Skin changes may resemble cellulitis initially, but ulceration, scabs, and fluid draining from the site develop, sometimes rapidly (Fig. 3). GAS organisms then can spread to the bloodstream and the patient can develop bacteremia and septic shock with high fever and a low blood pressure.

75 mg/kg/day PO divided every 8 hours for 60 days after exposure for penicillin-susceptible strains. 1 g PO every 8 hours for 60 days after exposure as an alternative for penicillin-susceptible strains for patients who cannot take first-line agents (i.e., fluoroquinolones, doxycycline) or if first-line agents are unavailable. The IDSA recommends 500 mg PO 3 times per day for 14-21 days in the absence of neurological symptoms. A double-blind, randomized trial compared amoxicillin (without probenecid) with azithromycin in patients with erythema migrans.

Although benzylpenicillin sodium is effective in the treatment of tetanus, metronidazole is preferred. Benzylpenicillin is inactivated by gastric acid and absorption from the gastro-intestinal tract is low; therefore it must be given by injection.

Penicillin-binding proteins vary among different bacterial species. Thus, the intrinisic activity of amoxicillin, as well as the other penicillins, against a particular organism depends on their ability to gain access to and bind with the necessary PBP. The aminopenicillins are able to penetrate gram-negative bacteria more readily than are the natural penicillins or penicillinase-resistant penicillins due to the presence of a free amino group within the structure. Like all beta-lactam antibiotics, amoxicillin’s ability to interfere with PBP-mediated cell wall synthesis ultimately leads to cell lysis. Lysis is mediated by bacterial cell wall autolytic enzymes (i.e., autolysins).

The relationship between PBPs and autolysins is unclear, but it is possible that the beta-lactam antibiotic interferes with an autolysin inhibitor. According to the manufacturer, amoxicillin should not be used in patients with mononucleosis as a high incidence of skin rashes have been reported in these patients. 1,000 mg PO twice daily with metronidazole (500 mg PO twice daily) and omeprazole (20 mg twice daily) for 10 to 14 days. For patients with an active ulcer, an additional 14 days of omeprazole (20 mg once daily) is recommended for ulcer healing. According to ACG, any standard dose PPI may be substituted for omeprazole in this regimen.

1 g PO every 8 hours as an alternative for penicillin-susceptible strains for patients who cannot take first-line agents (i.e., ciprofloxacin, doxycycline) or if first-line agents are unavailable. Treat for 7 to 10 days for naturally acquired infection. For a bioterrorism-related event, treat for a total duration of 60 days. Following initial treatment for severe anthrax infection, amoxicillin as a single agent may also be used as follow-up treatment. Based on manufacturer data, geriatric patients (above 65 years) do not respond differently to amoxicillin treatment than younger patients.

Tonsillitis is usually not serious unless a tonsillar abscess develops. When this happens, the swelling can be severe enough to block your child’s breathing. Ear infections and adenoid problems (swellings at the back of the nasal cavity above the tonsils) may occur at the same time. The tonsils are two masses of lymphatic (immune system) tissue located at the back of the throat.

If no abscess is present, the antibiotic usually starts to clear the infection within 48 hours.

Tonsillitis is an infection of the tonsils. The tonsils are two small glands found at the back of the throat behind the tongue. The function of these glands is not entirely clear, but research suggests that they help to fight infections. Early treatment of deep infections (for example, excision, drainage, and antibiotic treatment of rectal abscesses) helps prevent invasive GAS disease.
