We present a case of Lemierre syndrome characterized by thrombophlebitis of the internal jugular vein with multiple metastatic foci after acute otopharyngeal infection in a 30-year-old woman. Despite treatment with tonsillectomy leading to a diagnosis of peritonsillar abscess, her condition worsened and she was admitted with high fever. Chest radiograph and CT scan of the thorax revealed multiple pulmonary cavities and pleural effusion on the right side. On neck CT, a thrombus was detected in the left internal jugular vein. She received with intravenous clindamycin (CLDM) and cefepime (CFPM) and progressively improved. Although Lemierre syndrome is a relatively uncommon disease with the potentially life-threatening complication of acute pharyngotonsillitis, this syndrome should be considered in cases of severe tonsillitis or pharyngitis.

The goal of this meta-analysis was to evaluate the effectiveness of clarithromycin versus most commonly used treatments for upper respiratory infections. We performed a systematic review of comparative clinical trials found in the literature. Regarding effectiveness, no significant differences were found in comparisons between clarithromycin and amoxicillin-clavulanic acid for upper respiratory infections, nor for cephalosporins, amoxicillin or amoxicillin-clavulanic acid for otitis media, nor oral penicillin for classic streptococcal tonsillitis. Clarithromycin was more effective than betalactam antibiotics for sinusitis (OR: 1.27, 95% CI: 1.01-1.61 in intent-to-treat analysis). The effectiveness of clarithromycin was better than that for azithromycin, but only reached statistical significance in the per-protocol analysis. The global analysis including all 33 clinical trials showed a small benefit for clarithromycin reaching statistical significance in the fixed-effects model (OR: 1.12, 95% CI: 1.01-1.25). Regarding safety, the incidence of adverse events was significantly lower for clarithromycin compared to amoxicillin and amoxicillin-clavulanic acid. No differences were found when comparing adverse events due to cephalosporins, azithromycin and betalactam antibiotics, but the incidence of adverse events for clarithromycin was higher compared to that of oral penicillin for streptococcal tonsillitis treatment. Overall, all the compared drugs were well tolerated; discontinuations due to adverse events were very low: 2.2% for clarithromycin treatment and 2.5% for the other antibiotics. It was concluded that clarithromycin is an effective and safe treatment for upper respiratory infection, and its new formulation in a single daily dose may improve therapeutic compliance.

We have derived and characterized a highly pathogenic molecular isolate of feline immunodeficiency virus subtype C (FIV-C) CABCpady00C. Clone FIV-C36 was obtained by lambda cloning from cats that developed severe immunodeficiency disease when infected with CABCpady00C (Abbotsford, British Columbia, Canada). Clone FIV-C36 Env is 96% identical to the noninfectious FIV-C isolate sequence deposited in GenBank (FIV-Cgb; GenBank accession number AF474246) (A. Harmache et al.) but is much more divergent in Env when compared to the subgroup A clones Petaluma (34TF10) and FIV-PPR (76 and 78% divergence, respectively). Clone FIV-C36 was able to infect freshly isolated feline peripheral blood mononuclear cells and primary T-cell lines but failed to productively infect CrFK cells, as is typical of FIV field isolates. Two-week-old specific-pathogen-free cats infected with FIV-C36 tissue culture supernatant became PCR positive and developed severe acute immunodeficiency disease similar to that caused by the uncloned CABCpady00C parent. At 4 to 5 weeks postinfection (PI), 3 of 4 animals developed CD4(+)-T-cell depletion, fever, weight loss, diarrhea, and opportunistic infections, including ulcerative stomatitis and tonsillitis associated with abundant bacterial growth, pneumonia, and pyelonephritis, requiring euthanasia. Histopathology confirmed severe thymic and systemic lymphoid depletion. Interestingly, the dam also became infected with a high viral load at 5 weeks PI of the kittens and developed a similar disease syndrome, requiring euthanasia at 11 weeks PI of the kittens. This constitutes the first report of a replication-competent, infectious, and pathogenic molecular clone of FIV-C. Clone FIV-C36 will facilitate dissection of the pathogenic determinants of FIV.

Although infection by Corynebacterium diphtheriae is a model of extracellular mucosal pathogenesis, and diphtheria is one of the most worried diseases, this microorganism can be associated also with invasive infections such as endocarditis, septic arthritis, and osteomyelitis. Invasive infections are usually caused by non-toxigenic C. diphtheriae strains. Over the last years severe pharyngitis/tonsillitis associated with the isolation of non-toxigenic C. diphtheriae have been described. Penicillin treatment failure of these infections could only partially be explained by penicillin tolerance of the causing strain. Thus, we examined the in vitro ability of non-toxigenic C. diphtheriae throat clinical isolates to adhere to, and enter human respiratory epithelial cells. Trasmission and scanning electron microscopy demonstrated intracellular C. diphtheriae in laryngeal (HEp-2 cells) and pharyngeal (Detroit D562 cells) tissue culture. Live intracellular bacteria were detectable up to 48 h post-infection. Using a variety of compound that act on eukariotic cell structures, the internalization of C. diphtheriae seems to occur via a zipper-like mechanism. It is likely that internalization of C. diphtheriae can be involved in throat colonization contributing to bacterial eradication failure and asymptomatic carriage.

Mitochondrial diseases are primary defects in bio-energy metabolism. They are a heterogeneous group of diseases. The specific constellation of symptoms that will manifest in the effected individual depends on the type of genetic defect in the mitochondria. The goals of medical management, expressed in a highly simplified fashion, are to maintain a normal acid-base balance and to avoid those medical conditions and situations that add extra stress to a compromised bio-energy production system. Infection is a common stress that may cause a crisis in a patient with mitochondrial dysfunction. Treatment and avoidance of infections is a goal of both medical and surgical management. Common childhood illness such as otitis media, tonsillitis and sinusitis are example of such stress inducing infections.

The genetic diversity of group A streptococcal (GAS) isolates obtained in 1990 from Ethiopian children with various streptococcal diseases was studied by using emm gene sequence analysis. A total of 217 GAS isolates were included: 155 and 62 isolates from throat and skin, respectively. A total of 78 different emm/st types were detected among the 217 isolates. Of these, 166 (76.5%) belonged to 52 validated reference emm types, 26 (11.9%) belonged to 16 already recognized sequence types (st types) and 25 (11.5%) belonged to 10 undocumented new sequence types. Resistance to tetracycline (148 of 217) was not correlated to emm type. Isolation rate of the classical rheumatogenic and nephritogenic strains was low from cases of acute rheumatic fever (ARF) and acute glomerulonephritis (AGN), respectively. Instead, the recently discovered st types were overrepresented among isolates from patients with ARF (3 of 7) and AGN (9 of 16) (P < 0.01) compared to isolates from subjects with tonsillitis and from healthy carriers (10 of 57 and 16 of 90, respectively). In contrast to rheumatogenic strains from the temperate regions, more than half of the isolates from ARF (four of seven) carried the genetic marker for skin preference, emm pattern D, although most of them (six of seven) were isolated from throat. Of 57 tonsillitis-associated isolates, 16 (28%) belonged to emm pattern D compared to <1% in temperate regions. As in other reports emm patterns A to C were strongly associated with throat, whereas emm pattern D did not correlate to skin. This first large-scale emm typing report from Africa has demonstrated a heterogeneous GAS population and contrasting nature of GAS epidemiology in the region.

Acute tonsillitis is a common condition and usually runs a benign course. However life-threatening complications do still occur, even in this postantibiotic era. Infection can spread downwards into the mediastinum through the anatomic cervical spaces, causing widespread cellulitis, necrosis, abscess formation and sepsis. We present a case of descending mediastinitis in an 18-year-old woman, arising from her first episode of tonsillitis and treated successfully by surgical drainage. We believe that an awareness of this complication, early diagnosis using computed tomography scanning, and prompt, adequate surgical drainage will reduce morbidity and mortality.

Neutrophil dermatosis of the dorsal hands (NDDH) is a recently described skin manifestation regarded as a subset of acute febrile neutrophilic dermatotis (Sweet syndrome). We describe 5 cases with pustular and ulcerative plaques and/or bullae and vesicles of the dorsal hands. Three of the patients also had skin changes at sides other than the hands. Associated conditions were found in two patients, one patient treated with hemo-dialysis for chronic glomerulonephritis, and one patient had suffered from a streptococcal tonsillitis prior to the eruption. Two of the patients had fever, two had neutrophil leucocytosis in peripheral blood and two had elevated sedimentation rates. Histological findings showed signs of vasculitis in biopsies from two of the patients. NDDH is discussed on the basis of prior case reports concerning the subject, and it is concluded that Neutrophil dermatosis of the dorsal hands should be regarded as a localized variety of Sweet syndrome.

The tonsils are part of Waldeyer's ring, the basic function of which is antibody formation; they react later against a wide variety of antigens. Allergic sensitization of the airways occurs not only in the mucosa of the afflicted organ, but also in the lymphatic stations draining these structures. The lymphatic structures closest to the nasal mucosa in humans are the adenoids and tonsils. Adenoidal, nasal, and middle ear diseases are frequent health problems in young children. Pediatric adenoidal obstruction of the nasal airway is associated with significant morbidity and is also a frequent indication for surgery. Research done with respect to Waldeyer's ring in people dealing concurrently with allergy is a seldom subject in medical literature, both Polish and world wide. The study shows that allergy and sensitivity to different kinds of allergens are risk factors for adenoid hypertrophy (AH) in children. Histopathological and immunohistochemical studies confirms that tonsil dendritic cells, macrophages, eosinophils, and mast cells are involved in and are important in allergic tonsillitis. Ig synthesis and switching also occur in the adenoid and tonsils. Early treatment of allergic diseases may help reduce the occurrence of AH. Properly administered nasal steroids and antihistamines can reduce adenoidal hypertrophy and nasal airway obstructive symptoms in atopic children.
