The effect of chemoprophylactic use of rifampin and minocycline on rates of carriage of Neisseria meningitidis in army recruits in Finland.

During an epidemic caused by sulfonamide-resistant group A Neisseria meningitidis (A SuR strain), rifampin (600 mg per day for four days) or minocycline (100 mg every 12 hr for five days) was administered as chemoprophylaxis to 1,540 unvaccinated recruits in the Finnish Armed Forces. Rates of carriage of all strains of N. meningitidis were initially reduced by 78% (from 60% to 13%) in the 389 men receiving rifampin and by 62% (from 70% to 26%) in the 1,151 men receiving minocycline but rose to approximately 30% in both groups four weeks after prophylaxis. The carriage of A SuR strains was similarly reduced. An individual follow-up of 636 trainees demonstrated a high rate of new infections. It is suggested that the long-term inefficiency of rifampin and minocycline is due to their inability to reduce the carriage rates enough to prevent further spread of infection after prophylaxis is descontinued. However, no new cases appeared among the men receiving the prophylaxis. Five strains highly resistant to rifampin were found after the use of rifampin (minimal inhibitory concentration, greater than or equal to 100 microgram/ml), but no minocycline-resistant strains were encountered. No unpleasant side effects were seen in subjects receiving either drug.

Agammaglobulinemia with arthritis and celiac disease developing after infectious mononucleosis. Follow-up study of a case.

A previously healthy 2 1/2-year-old boy from a healthy family developed agammaglobulinemia with arthritis 3 months after infectious mononucleosis (IM). The response of serum immunoglobulins at the initial stage of IM was typical, with greatly elevated IgM and a positive IM-specific heterophil antibody test. A secondary celiac disease was diagnosed one year after IM. Considering the serum immunoglobulin levels and the normal half-lives of IgM and IgG, it seems very probable that the synthesis of immunoglobulins ceased about one month after the onset of IM. The role of suppresor T-cells in the development of acquired secondary agammaglobulinemia is discussed.

A study on the mutagenic activity of styrene and styrene oxide.

Styrene oxide is multagenic, without metabolic activation, to S. typhimurium strains TA 1535 and TA 100, which have been devised to detect mutagens causing base-pair substitutions. Styrene seems to be mutagenic toward the same strains, but only after metabolic activation. The toxicity of both styrene and styrene oxide make the construction of reliable dose-response curves rather difficult. Diethylmaleate and 3,3,3-trichloropropene oxide enhanced the mutagenicity of styrene oxide in the presence of homogenate; this result indicates the participation of epoxide hydratase and glutathione S-oxide transferase in the metabolism of styrene oxide. These two chemicals did not influence the mutagenic activity of styrene. Styrene glycol and 4-tert-butyl-brenzcatechin were not mutagenic to any of the strains studied. Results show that further, more detailed experimental and, possibly, epidemiologic studies are warranted.

Immunosuppressive effect of radiotherapy on patients with lung cancer.

The immunoglobulins A, E, G and M of 25 patients with lung cancer were determined (by radial immunodiffusion) before, during and after radiotherapy. No significant change in any immunoglobulin were noticed overall. In the group with a poor prognosis (survival less than 12 months; 15 patients), there was a significant decrease of IgA and IgM one month after the irradiation. In the group of patients with pulmonary infection (14 patients), the level of IgA, IgG and IgM were lower than in the group without infection throughout the examination period. Cellular immunity measured by the PPD skin test, showed no significant differences between the groups by survival.

Middle ear specific proteins in glue ears.

Two rabbits were immunized with a pool of mocoid secretion from glue ears. The ear fluids formed up to three specific protein precipitation lines with the absorbed immune serum. One of these proteins was identified as containing acid and another as containing neutral glycoproteins, the third component remained unidentified. The data bring out new evidence of the active secretory capacity of the middle ear mucosa in secretory otitis media.

Penetration of azidocillin into the secretion and tissues in chronic maxillary sinusitis and tonsillitis.

The penetration of azidocillin into the sinus mucosa and secretion as well as into tonsils and adenoids was studied. Altogehter 73 patients were included and they were arranged in four groups according to age, diagnosis and drug dose. The average azidocillin concentration was satisfactory and predictable in all tissues and well over the MIC for most upper respiratory tract pathogens studied. In the maxillary antrum secretion the values were much lower and in many cases under the MIC for hemophilus. This is thought to depend upon the drug's being bound to proteins in the secretions. The clinical results were good in all cases and the contribution of the surgical operation, particularly in providing drainage for the secretion, is obvious.

Aminotransferases in post-mortem cochlear fluids.

Aspartate and alanine aminotransferase (ASAT, ALAT) activities were measured in human post-mortem sera, cerebrospinal fluid (CSF), perilymph and endolymph. Due to heart and/or liver morbidity during a terminal illness, the ASAT and ALAT serum activities were considerably increased as compared with normal and both were 20--30 times higher (p less than 0.001) than in CSF or inner ear fluids. CSF and inner ear fluids showed mutually similar values.

Fluid pathways in temporal bones.

Five temporal bones were serially sectioned and studied concerning spread of erythrocytes and blood-derived precipitate in patients who died from subarachnoid hemorrhage. Erythrocytes followed the natural pathways--the cochlear aqueduct, the cochlear, vestibular, facial and glossopharyngeal nerves, and were demonstrable in the inner ear fluid spaces. The temporal bone marrow spaces were also filled with erythrocytes, particularly in the hypotympanal area. In the microimmunoelectrophoresis, no specific precipitation lines formed between the anti-CSF serum from rabbits and middle ear exudate from human ears with acute otitis media. Although, in animals, middle ear spaces have been shown to be connected to the middle ear space this does not seem to apply to human ears, and CSF fluid components are not involved in the formation of middle ear exudate.
