Four cases of gonococcal pharyngotonsillitis have been presented, along with a review of the world literature. This entity is most commonly seen in those individuals practicing fellatio, i.e., females and homosexual males. The infection may be passed to the newborn by the infected genitals of the mother during birth, to the infant from adult molestation, or among sexually promiscuous children. Most gonococcal pharyngeal infections result in a carrier state, and as such, are possible reservoirs of propagated infections. When symptomatic, the most frequent complaint is a sore throat. Physical finding among symptomatic patients reveal a wide spectrum ranging from mild hyperemia of the pharynx or tonsils, to exudative tonsillitis with tender cervical lymph nodes and moderate elevation of temperature. Most authorities agree that the preferred treatment is 4.8 million units of procaine penicillin G I.M., with one gm of probenecid by mouth thirty minutes before the injection. If allergic to penicillin, tetracycline should be given, 1.5 gm by mouth stat, then 0.5 gm four times a day for a total of 9 gm. A routine blood agar culture of the throat will not reveal the presence of the gonococcus. Thayer-Martin (or Transgrow) media must be used. Failure to detect pathogenic bacteria in a routine culture may lead to either no treatment or improper treatment of a gonococcal pharyngotonsillar infection. This may result in a carrier state, or even worse, to a disseminated gonococcal infection.

The Poor

During a 10-year period, antibiotics were assigned in random, double-blind fashion in six combinations to treat 948 episodes of otitis media in children. Exudate from the middle ear of all patients was cultured before treatment. Three follow-up visits were conducted; the first follow-up visit was three to five days after the start of therapy, and the second and third visits were 14 and 31 days after onset of treatment. Exudates were recultured for 75% of the patients on the first follow-up visit. Comparison of treatment results showed that triple sulfonamide combined with either phenoxymethyl penicillin, or benzathine and procaine penicillin G given intramuscularly (IM) was as effective as was ampicillin or amoxicillin. Phenoxymethyl penicillin and cyclacillin alone were usually effective against pneumococci but relatively ineffective against Haemophilus influenzae. Cefaclor and trimethoprim-sulfamethoxazole produced unsatisfactory results in about half the cases caused by pneumococci or H influenzae. Although production of β-lactamase by some otitis-causing Haemophilus and Staphylococcus species may explain the ineffectiveness of some treatments, the percentage of organisms positive for β-lactamase was too small to be responsible for the poor results with certain drugs.

Pediatric Use

Table I summarizes most of the pertinent data in this report on the serum penicillin concentrations 12 and 24 hours after intramuscular injection of K penicillin G in peanut oil and beeswax, which is fluid at room temperature, and of three different procaine penicillin preparations. These three preparations are procaine penicillin G in sesame oil, procaine penicillin G in peanut oil with 2% aluminum monostearate, and procaine penicillin G in water with Na-carboxymethylcellulose. When they were given in a dosage of 8000 u./lb. to infants and children, weighing between 4.5 and 18.0 kg., there was no statistically significant difference in the serum levels obtained. A dosage schedule for these preparations is suggested for pediatric use. The aqueous preparation offers some advantages which are discussed. Experiences are reported which emphasize the necessity of avoiding intravenous administration of all these preparations.

Csf Levels

Simultaneous serum and CSF samples were obtained following the intramuscular administration of 50,000 units/kg of aqueous procaine penicillin G in 25 neonates. Penicillin activity was detected in the sera and CSF of all patients. Peak serum levels were noted at four hours (mean ± SEM, 17.1 ± 6.3 µg/ml). Peak CSF levels were noted at 12 hours (0.70 ± 0.35 µg/ml). The serum level at 24 hours was 2.1 ± 0.98 µg/ml (range, 0.2 to 5.8 µg/ml); the CSF level at 24 hours was 0.12 ± 0.05 µg/ml (range, 0.03 to 0.27 µg/ml). These results demonstrate that spirocheticidal levels (≥0.03 µg/ml) are achieved for at least 24 hours in the CSF following the intramuscular administration of aqueous procaine penicillin G in neonates.
