The role of three oral flora organisms (Prevotella intermedia, Porphyromonas gingivalis, and Actinobacillus actinomycetemcomitans) was investigated in 31 children with recurrent nonstreptococcal tonsillitis. Antibody titers to the three organisms were measured by enzyme-linked immunosorbent assay in the 31 patients, as well as in 32 control patients who had not suffered from recurrent tonsillitis. None of the individuals in either group suffered from periodontal or dental illness. Significantly higher antibody levels to P intermedia were found in the study group as compared to controls (median 91.0 versus 72.5; p = .02). In contrast, the antibody titers to the other two organisms were generally low (less than 0.30), and no difference was found among the two study groups. The elevated antibody levels to P intermedia, a known oral pathogen that is also isolated from most recurrently inflamed tonsils, suggest a pathogenic role for this organism in recurrent tonsillitis.

The incidence of oral alpha-streptococcus with inhibitory activity against group A streptococcus, as a defense mechanism against bacterial infection in the oral cavity, was investigated in pediatric individuals with tonsillitis. Infection by group A streptococcus appeared to be common in children, because the detection rate of inhibitory alpha-streptococcus in healthy children as well as pediatric patients with tonsillitis was lower than in adults and elderly patients. In particular, the detection rate of these strains was predominantly low in patients with beta-streptococcus. Among pediatric patients scheduled for tonsillectomy, the detection rate of inhibitory alpha-streptococcus was low preoperatively. However, the rate was markedly increased after surgery. The high postoperative detection rate of these strains reflected the decreased incidence of group A streptococcal infection. The results of this investigation of bacterial interference between oral alpha-streptococcus and group A streptococcus suggested that surgical treatment is a more effective approach for improving the oral bacterial flora in children with recurrent tonsillitis.

A correctly prescribed constitutional homoeopathic remedy can increase well-being in the preconceptual period. For infertility, orthodox investigations are essential but where tests are normal then homoeopathic treatment of both pariners can maximise their health and may improve the chances of conception. Homoeopathic remedies can be effective for morning sickness and before and during labour. Arnica is helpful for internal and external bruising of both mother and newborn infant. Some problems of breast feeding respond to the homoeopathic remedy Lac-caninum. There is no harm in trying homoeopathy initially for postnatal depression, although severe cases will need orthodox medication. In most conditions there is time to try the holistic stimulus of a homoeopathic remedy to attempt to persuade the body to heal itself. This is a very different principle from the so-called enlightened attitude of some health professionals that there is no harm in trying homoeopathy when orthodox treatment can do no more for the patient. In babies, teething often responds to Chamomilla. The child's susceptibility to certain illnesses, eg recurrent tonsillitis, can be helped by a "whole-patient" homoeopathic remedy, although penicillin may be needed for acute attacks of tonsillitis. In chronic conditions of childhood such as eczema and asthma, homoeopathic doctors believe that correctly chosen remedies are often able to stimulate the body's innate healing ability, leading to an improvement.

The immune function of tonsils and the immunological mechanisms of focal tonsillitis are still controversial. We do have some knowledge about the structure of tonsillar cells, but their functional status is still not clear. In 40 cases of chronic recurrent tonsillitis and 20 cases of focal tonsillitis with glomerular nephritis, cell culture of tonsillar lymphocytes was removed in vitro and 3H-tymidin incorporation applied to investigate the spontaneous DNA synthesis of tonsillar lymphocytes. The results demonstrated that: i) In chronic tonsillitis, spontaneous DNA synthesis of tonsillar lymphocytes in children is significantly stronger than that in adults (19,946 +/- 5,612 vs 9,216 +/- 5,702 cpm) (p <0.01). ii) Spontaneous DNA synthesis of tonsillar lymphocytes in focal tonsillitis is significantly stronger than that in the chronic recurrent tonsillitis in patients of the same age (25,307 +/- 12,231 cpm vs 12,455 +/- 7,914 cpm) (p <0.01). This indicates that the tonsillar lymphocytes are active in focal tonsillitis, can produce large amounts of memory B-cell clones, which reach other parts of the body through the blood and cause autoimmune reaction which can be blocked by tonsillectomy, thus curing the systemic disease.

The antibodies to LTA of Streptococcus pyogenes (S. pyogenes) and of Staphylococcus aureus (S. aureus) in sera from 110 children with or without recurrent tonsillitis were assayed by enzyme-linked immunosorbent assay (ELISA). The antibody of IgA class was not detected in any sera. There was a significant positive correlation between IgG and IgM antibody levels to LTA of S. pyogenes and those to LTA of S. aureus. There was no significant correlation between anti-LTA IgM antibody and age or episodes of tonsillitis. However, serum anti-LTA IgG levels in younger patients ( < or = 7 y.o.) were significantly lower than those in their elders (>7 y.o.) (anti-S. pyogenes; p = 0.0007, anti-S. aureus; p = 0.007). Serum anti-LTA IgG antibody levels correlated inversely with episodes of tonsillitis in younger patients ( < 7 y.o.) (S. pyogenes: r = -0.362, p = 0.0082, S. aureus: r = -0.276, p = 0.047). These findings suggest that systemic hyposensitivity to LTA of S. pyogenes and S. aureus may be a possible cause of habitualness of tonsillitis in young children.

It seems that there are clinical differences between tonsillitis in children and adults. In order to verify whether such a supposed clinical subdivision be true, tonsillar mononuclear cells from 20 children operated on for recurrent tonsillitis caused by a common flora and 20 adult patients with an indication for surgery for chronic tonsillitis were studied by means of monoclonal antibodies (MoAbs) specific for the antigens associated with each stage of the inflammatory response. BMA 4D10 and BMA 27E10 MoAbs were used as markers for the early stages, BMA RM 3/1 for the intermediate stage. BMA 25 F 9 for the late stage, and BMA G 16/1 for the chronic stage. The results indicate that chronic tonsillitis in the adult should be considered as such (higher expression of antigens associated with the chronic stages (p = 0.039), low and even lower expression of those associated with the intermediate and acute stages, respectively), whereas tonsillitis in children could perhaps be more correctly regarded as an expression of recurrent inflammation (higher expression of antigens associated with the acute stages (p = 0.022)). Results are presented and discussed.

There are only few studies on the normal bacteriology of tonsils. The purpose of this study was to acquire knowledge about the normal microflora: patients without recurrent tonsillitis (RT) and without tonsil hypertrophy (TH) and to compare these results with the pathological microflora: patients who have recurrent tonsillitis and/or tonsillar hypertrophy. We did 132 cultures of tonsil surface obtained from normal children and 96 cultures from pathological surfaces during the summer and in the winter. Comparing normal and pathological groups, we found Neisseria spp and Enterobacteria spp more frequently in the normal group. There are differences in the surface microflora of tonsils from normal persons and from individuals with tonsillitis.

The purpose of this study was to ascertain to what degree the clinical entity recurrent tonsillitis (RT) is associated with a histopathological pattern of chronic tonsillitis. Cases of idiopathic tonsillar hypertrophy (ITH) not associated with recurrent infections were used for comparison. We performed a histopathological study of 126 palatine tonsils of children (57 cases due to RT and 69 due to ITH). The following features were evaluated: cryptal reticulation, the relative amount of diffuse and follicular lymphoid tissues, the intensity of parenchymal fibrosis, the papillary arrangements of the epithelium, the amount of debris in the lumen of the crypts, and the presence of keratin cysts. There was no significant quantitative difference between the two groups (RT and ITH) and we did not find a histological distinctive pattern of RT or ITH. Recurrent infection in the tonsils in children is not associated with a histopathological pattern which could be termed chronic non-specific tonsillitis and is clearly distinguishable from idiopathic tonsillar hypertrophy.

Infection is a well-recognized triggering factor for both guttate and chronic plaque psoriasis. We investigated prospectively 13 patients with recalcitrant psoriasis exacerbated by recurrent tonsillitis, who underwent tonsillectomy between 1990 and 1993. There were 12 female patients and one male, with a mean age of 17 yr (range 6-28). Six patients had guttate psoriasis resistant to standard treatments and seven patients had chronic plaque psoriasis exacerbated by tonsillitis that was severe enough to warrant at least one admission to hospital. Patients were followed by chart review and postal questionnaire. Psoriasis was cleared completely after tonsillectomy in five out of the six patients (83%) with guttate psoriasis and was improved in one patient. Two out of seven patients with plaque psoriasis (29%) were cleared, two (29%) were improved and three (42%) were unchanged. We conclude that tonsillectomy may be a successful treatment modality in selected patients with recalcitrant guttate or chronic plaque psoriasis.

The histochemical localisation of two ecto-enzymes, 5'-nucleotidase (5'-NT) and Mg(2+)-ATPase, was investigated in hyperplastic and recurrent tonsillitis. Detection of enzymes was performed on frozen sections using the classical lead nitrate method. Activity of 5'-NT was demonstrated particularly in the cells of lymphoid follicles and in the basal layer of the surface tonsillar epithelium. There was no difference in localisation of 5'-NT between hyperplastic and recurrent tonsillitis, whereas a stronger reaction in follicular mantle zones was observed in recurrent tonsillitis compared to hyperplastic tonsillitis. Mg(2+)-ATPase activity was mainly associated with the cells lining the tonsillar crypt, with the interfollicular areas and blood vessels. In recurrent tonsillitis only half of the studied follicular germinal centres expressed Mg(2+)-ATPase activity, compared to hyperplastic tonsillitis. The similar localisation of 5'-NT and ecto-ATPase in both types of chronic tonsillitis suggests that in inflamed tonsils expression of investigated enzymes probably does not depend on the type of chronic tonsillitis.
