An immunochromatography (IC) kit for human adenovirus (HAdV) was evaluated with 138 patient nasopharyngeal samples. The samples were collected at a sentinel clinic in Japan from January through June 2003. Patients were diagnosed by clinical manifestation of pharyngoconjunctival fever (n = 38) or exudative tonsillitis (n = 100). The IC kit was positive for 84% (116 of 138) of patients diagnosed at bedside. The remaining extract solution of the IC kit test was transferred into maintenance medium and tested via laboratory diagnoses. The IC kit had 95% sensitivity (116 of 122 patients) with HAdV isolation (isolation) as the standard and 91% sensitivity (116 of 128 patients) with PCR as the standard. All of the IC kit-positive samples were isolation and PCR positive. Similarly, all the isolation-positive samples were PCR positive. Twenty-two IC kit-negative samples were evaluated by real-time PCR. Six samples were IC kit negative and isolation positive and contained 3.8 x 10(7) to 2.5 x 10(9) copies of the HAdV genome/ml. Five samples that were only PCR positive contained 3.0 x 10(4) to 3.8 x 10(5) copies of the HAdV genome/ml, but one sample was real-time PCR negative. We conclude that the IC kit is a useful bedside diagnostic tool for HAdV infections because it has 95% sensitivity (compared to isolation), but a negative result does not always rule out HAdV infection.

Our study hypothesized that cytokines or chemokines induced in tonsils by infectious stimulations play an important role on the exacerbation of the glomerular injuries in patients with IgA nephropathy (IgAN). Tonsils from six patients with IgAN diagnosed by renal biopsy were studied after getting their written informed consents Tonsils from six patients with tonsil disorders with non-renal disorders were examined as controls. Tonsillar mononuclear cells (TMCs) were isolated and resuspended with RPMI 1640 with 10% FCS. These cells were incubated for 48 h with staphlococcus enterotoxin-B (SEB) or lipopolysaccaride (LPS). The levels of IL-6, IL-8, IL-12 and MCP-1 in the supernatants were measured by solid-phase enzyme-linked immunosorbent assay (ELISA) kits. The actual cytokine concentrations were calculated by determining the standard curves. The experiments were performed in duplicate, and the mean value was calculated. We found that tonsillar mononuclear cells of IgA nephropathy produced mesangial proliferative chemokines (MCP-1, IL-8) in higher amounts compared to tonsils from non-IgA nephropathy. This result suggests that upper respiratory tract infections such as tonsillitis may be one of the risk factors of the aggravation in patients with IgA nephropathy.

The temporal association of tonsillitis and hematuria or proteinuria in IgA nephropathy suggests that there might be a link between the physiological properties of the secondary lymphoid organ that tonsils represent and the mesangial deposition of IgA characteristic of this nephropathy. A number of clinical and ex-vivo data support this hypothesis. One of the earliest was the demonstration of the dimeric nature of mesangial IgA, composed of IgA monomers linked by a J chain, yet lacking the polyIg receptor acquired by secretory IgA during transcytosis through epithelial cells. This molecular structure is that of IgA synthesized in human tonsils, the epithelium of which lacks polyIg receptor. Moreover, tonsils from patients with IgA nephropathy display an abnormal partition of IgG and IgA producing plasma cells associated with a significantly developed web of high endothelial venules. IgA nephropathy could thus be in part related to an alteration of IgA precursors homing in tonsils. Tonsillectomy thus would present the advantage of removing an abnormally functioning source of dimeric IgA. Performed early enough in the course of the renal disease, tonsillectomy could suffice to halt the development of the nephropathy and restore the kidneys to health.

We have previously reported that clinical remission could be achieved by combination therapy consisting of steroid pulse therapy and tonsillectomy in patients with IgA nephropathy. However, there is no consensus as to the indications for tonsillectomy in IgA nephropathy (IgAN) patients. To clarify whether there is any correlation between characteristics of removed palatine tonsils and clinical remission rate, we evaluated the relationships between the remission rate of urinary abnormalities and characteristics of 186 IgAN patients (aged 11-65 years) with mild or moderate renal pathology and their tonsils. Remission of proteinuria was observed in 134 patients (72%) and remission of hematuria was observed in 111 patients (60%). There was no significant difference in remission rate of either proteinuria or hematuria in terms of the past history of recurrent tonsillitis, episodes of synpharyngitic gross hematuria, pus plugs in the tonsillar lacunae, size of tonsils, age and the results of tonsillar provocation tests. Our findings suggest that it is very difficult to predict the efficacy of tonsillectomy and steroid pulse therapy based on the gross appearance of tonsils, the tonsillar provocation test or clinical episodes of tonsillitis. Moreover, contraindication of tonsillectomy for aged IgAN patients is not always justified.

In the period of 30 years, i.e. from 1973 to 2002, we noticed in Croatia 6 sudden and unexpected cardiac deaths in male athletes during or after training. Two were soccer players, 2 athletic runners, one was a rugby player and one was a basketball player. All of them were without cardiovascular symptoms. At the forensic autopsy, the first athlete, aged 29, had chronic myocarditis and thickened left ventricular wall of 15 mm. The second, aged 21, had an acute myocardial infarction of the posterior wall with normal coronaries and thickened left ventricular wall of 15 mm. The third aged 17, had hypoplastic right coronary artery and narrowed ascending aorta, suppurant tonsillitis and subacute myocarditis. Two athletes, aged 29 and 15, had hypertrophic cardiomyopathy and normal coronaries, and one dilated aorta. The sixth, aged 24, had arrhythmogenic cardiomyopathy of the right ventricle. All the 6 athletes died suddenly, obviously because of malignant ventricular arrhythmias. In Croatia the death rate among athletes reached 0.15/100 000, in others who practice exercise reached 0.74/100,000 and the difference is highly significant (c2=14.487, Poisson rates=3.81, P=0.00014) and in physicians-specialists reached 33.6/100,000. Preventive medical examinations are essential, especially in athletes before physical exercise, as are other investigations in every case suspicious of heart disease, including electrocardiogram (ECG), stress ECG, echocardiography and stress-echocardiography and other findings if indicated. Physical exercise is contraindicated in acute respiratory infection: in 2 of those cases had been a cause of death as a trigger.

This review summarizes the information that supports the potential importance of anaerobic bacteria in the pharyngo-tonsillitis (PT) associated with infectious mononucleosis (IM). Evidence supportive of the potential of involvement of bacteria in IM was provided by several studies that showed increased recovery of bacteria on the tonsillar surfaces in IM. Several studies demonstrated that metronidazole therapy alleviated the clinical symptoms of tonsillar hypertrophy and shortened the duration of fever in IM. Metronidazole has no antimicrobial activity against aerobic bacteria and is only effective against anaerobic bacteria. A possible mechanism of its action is the suppression of the oral anaerobic flora that might contribute to the inflammatory process induced by the Epstein-Barr virus. This explanation is supported by the increased recovery of Prevotella intermedia and Fusobacterium nucleatum from the tonsillar surfaces during the acute phases of IM and an immune response against these organisms by patients with IM. Although more studies are needed, these findings support the possible pathogenicity of Gram-negative anaerobic bacteria in the PT associated with IM.

The purpose of this study was to compare the frequency of recovery of aerobic and anaerobic organisms with interfering capability against group A beta-haemolytic streptococci (GABHS) and beta-lactamase-producing bacteria (BLPB) from the tonsils of GABHS carriers and non-carriers. The presence of aerobic and anaerobic bacteria capable of such interference in vitro was evaluated in cultures obtained from the tonsils of 20 healthy children who were non-GABHS carriers and 20 who were GABHS carriers, and also from 20 children who were asymptomatic after completing a course of penicillin for acute GABHS pharyngo-tonsillitis (PT) and were non-GABHS carriers and 20 who were GABHS carriers. In healthy children, 32 interfering isolates were recovered from 16 non-GABHS carriers (1.6 per child) and 13 were isolated from 7 GABHS carriers (0.65 per child) (P<0.001). In children who had suffered acute GABHS PT, 26 interfering organisms were recovered from 15 non-GABHS carriers (1.3 per child) and 8 were isolated from 5 GABHS carriers (0.4 per child) (P<0.005). In healthy children, 13 BLPB were recovered from 5 non-GABHS carriers and 13 were isolated from 6 GABHS carriers. In children who had suffered acute GABHS PT, 14 BLPB were recovered from 5 (25 %) non-GABHS carriers and 32 were isolated from 17 (85 %) GABHS carriers (P<0.05). It was demonstrated in this study that there was a higher rate of recovery of aerobic and anaerobic organisms capable of interfering with GABHS in non-GABHS carriers than in GABHS carriers. This was observed in all GABHS non-carriers and included healthy children as well as those recently treated for symptomatic GABHS PT with penicillin that failed to eradicate GABHS. A higher rate of recovery of BLPB was observed only in GABHS carriers who were treated with penicillin for GABHS PT.

Diseases of ear, nose and throat (ENT) often have serious consequences including hearing impairment, and emotional strain that lower the quality of life of patients. In Kenya, upper respiratory infections are among the most common infections encountered in outpatient facilities. Some of these infections are becoming difficult to control because some of the causing microorganisms have acquired antibiotic resistance and hence the need to develop new drugs with higher efficacy. Ethnobotanical studies have now been found to be instrumental in improving chances of discovering plants with antimicrobial activity in new drug development. In Kenya the majority of local people are turning to herbal remedies for primary health care needs. In most cases the sources of these remedies are undocumented and the knowledge about them passed orally form generation to generation, hence under threat of disappearing with current rates of modernisation. This study explored the traditional remedies used in managing various ENT diseases in seven districts of the Central Province of Kenya. The most common ENT conditions managed using traditional therapies include: common cold, cough, tonsillitis, otitis-media, chest pains and asthma. The results indicate that 67 species belonging to 36 plant families were utilized in this region. These plants were of varying habits; herbs (37.3%), shrubs (34.4%), trees (25.4%) as well as some grasses and sedges (3%). The traditional preparations were found to be made mainly from leaves (49%), roots (20.5%) and barks (12.5%). For each of the ENT conditions multiple species are utilized mainly as individual preparations but occasionally as polyherbal concoctions. In the case of common cold for example, 30 different species are used. Plants reported in this survey are important candidates for antimicrobial tests against ENT disease causing micro-organisms, especially those with antibiotic resistance.

Infants at day care centers tend to contract repetitive upper respiratory infections and prolonged otitis media. The increase in antimicrobial-resistant bacteria, particularly in infants, has given rise to a stubborn therapeutic problem. We studied the nasopharyngeal carriage and drug resistance to Haemophilus influenzae (H. influenzae) and Streptococcus pneumoniae (S. pneumoniae), the most common pathogens of upper respiratory infections, in infants at day care centers. Nasopharyngeal cultures of infants between the ages of 0 and 6 years were conducted at two day care centers in July 2004 ("summer"; n=183), and in February 2005 ("winter"; n=182). Isolated H. influenzae and S. pneumoniae were subjected to antibiotic susceptibility tests by broth microdilution. We also conducted an otolaryngological examination and a survey on past and life histories. H. influenzae in summer (38.3%) increased significantly in winter (57.7%). Beta-lactamase-negative and positive ampicillin-resistant H. influenzae (BLNAR+ BLPAR) in summer decreased significantly in winter. S. pneumoniae did not differ in summer (42.1%) or in winter (43.4%). Penicillin-resistant and intermediate S. pneumoniae (PRSP+PISP) was 41.3% in summer and decreased significantly to 19.0% in winter. BLNAR + BLPAR and PRSP + PISP differed with the day care center. In otolaryngological examination, rhinosinusitis was commonest (28.4% in summer and 30.8% in winter), followed by allergic rhinitis (8.7% in summer and 6.0% in winter) and otitis media (8.2% in summer and 6.0% in winter). Tonsillitis was minor (0.5% in both seasons). Rhinosinusitis in winter was significantly higher in carriers of H. influenzae and/or S. pneumoniae than in non carriers (36.4% versus 16.0%). Breast-fed infants tended to have less otitis media than bottle-fed infants (38.2% versus 52.9%). H. influenzae and/or S. pneumoniae plateaued (75-80%) after 12 months in day care centers. These results suggest that infants attending day care centers are immediately colonized by H. influenzae and S. pneumoniae in the nasopharynx after entering the centers. Nasopharyngeal drug-resistant H. influenzae and S. pneumoniae varied during the seasons and between day care centers. Further prospective studies are needed to determine upper respiratory tract infection in infants at day care centers and to evaluate carriage, epidemiology, and the drug-resistance rates of these pathogens.
