Uvulitis is an uncommonly reported disorder with the potential for significant morbidity. We describe three cases of uvulitis seen within a six month period in our emergency department. In two cases with respiratory distress, but without epiglottitis, Haemophilus influenzae was isolated from throat or blood cultures. The third case was associated with group A streptococcus tonsillitis and no respiratory compromise. Atypical presentations of upper airway infection with H. influenzae may be increasingly common.

In contrast to solid organ transplantation (Tx), the incidence of post-transplant lymphoproliferative disease (PTLD) after hematopoietic stem cell Tx (HSCT) is generally low. This risk, however, is significantly elevated in patients receiving human leukocyte antigen (HLA) mis-matched or T-cell-depleted grafts, or after treatment for severe graft-versus-host disease (GvHD). An 18-yr-old patient with positive Epstein-Barr virus (EBV) serology received a fully matched, unmanipulated bone marrow graft from an unrelated EBV-positive donor for treatment of acute myeloid leukemia (AML) in second complete remission. GvHD prophylaxis was performed with cyclosporin A (CsA) and a short course of methotrexate. Four months after Tx, the patient developed ulcerative tonsillitis that was unresponsive to antibiotic treatment. Diarrhea appearing simultaneously was interpreted as gastrointestinal GvHD and steroids were added to CsA. A few days later the patient was admitted to hospital because of generalized seizure and pneumonia. Despite reduction of immunosuppression, intensification of anti-viral treatment, and subsequent mechanical ventilation, the patient died of acute respiratory distress 6 days later. Autopsy demonstrated disseminated EBV-induced, multi-nodular lymphoma infiltration of the entire colon but no signs of GvHD. Moreover, both lungs, paratracheal lymph nodes, kidneys, thyroid gland, and liver were infiltrated with large B-cell non-Hodgkin's lymphomas. This case underlines the rapid and aggressive course of EBV-induced disseminated PTLD after HSCT, initially mimicking intestinal GvHD because of massive colonic lymphoma infiltration. Tissue biopsies should be performed early for establishing correct diagnosis, thus enabling specific therapy, e.g. infusion of donor leukocytes with cytotoxic T-lymphocytes.

Infection with influenza A (H5N1) virus, which has not been associated with respiratory disease in humans previously, caused clinical signs of acute respiratory distress syndrome and multiple-organ dysfunction syndrome with high mortality in humans in Hong Kong in 1997. To study the pathogenesis of this disease, we infected four cynomolgus monkeys (Macaca fascicularis) with 2.5 x 104 median tissue culture infectious dose (TCID50) of influenza virus A/Hong Kong/156/97 (H5N1) and euthanatized them 4 or 7 days after infection. The main lesion was a necrotizing broncho-interstitial pneumonia (4/4) similar to those found in primary influenza virus pneumonia in humans, with desquamation of respiratory epithelium (4/4), intra-alveolar hemorrhage (4/4), hyaline membrane formation (2/4), and infiltration with neutrophils and macrophages (4/4). Lesions in other organs consisted of a suppurative tonsillitis (2/4) and necrosis in lymphoid organs (1/4), kidney (1/4), and liver (1/4). By immunohistochemistry, influenza virus antigen was limited to pulmonary tissue (4/4) and tonsils (2/4). Based on these results, we suggest that the cynomolgus monkey is a suitable animal model for studying the pathogenesis of human H5N1 virus infection and that multiple-organ dysfunction syndrome in this disease may be caused by diffuse alveolar damage from virus replication in the lungs alone.

In this study, the clinical and laboratory features of 26 infectious mononucleosis (IMN) cases who have been diagnosed between the years of 1984-2005 were evaluated retrospectively. The mean age of the patients was 26+/-11 years, the rate of being hospitalized was 65%, and mean hospitalization period was 9.2+/-6 days. Fever (81%), weakness (50%), sore throat (50%), headache (50%) and swollen neck (35%) were the most common symptoms, while in the physical examination cervical lymphadenopathy (81%), splenomegaly (69%), hyperemic pharynx (65%), hepatomegaly (54%) and tonsillitis (50%) were observed. Laboratory results yielded leukocytosis in 21%, leucopenia in 12%, anemia in 44%, thrombocytopenia in 5% and elevated transaminase levels in 84% of the patients. Of the patients 15 (57.7%) had the history of using antibiotics before the diagnosis. Serological diagnosis was performed by Paul-Bunnel test and/or IgM positivity against Epstein-Barr virus (EBV) viral capsid antigen (VCA). Tonsillo-pharyngitis secondary to edema and respiratory distress due to lymphadenopathy pressure were detected in four patients, whereas pancytopenia was established only in one patient, as complications. This study emphasized that, although IMN is a self-limited infection, the diagnostic difficulties may arise when the clinical course is atypical, and rarely seen life-threatening complications may also develop during IMN course.

Aplasia or hypoplasia of the epiglottis in an adult is rarely reported congenital anomaly of the larynx. Most patients with epiglottic aplasia have presented fatal symptom of respiratory distress and severe aspiration in infancy or childhood. We present a case of congenital absence of the epiglottis found in a 33-year-old woman complaining of recurrent lingual tonsillitis. Laryngoscopic finding and CT scan revealed an isolated epiglottic aplasia and normal appearance of other laryngeal structure. This is the first description of physiologic evaluation in an epiglottic anomaly to find the compensatory mechanism of aspiration prevention. We discussed this case with a review of literature.

This is a systematic review of cases with Lemierre's syndrome (LS) in the past 5 years. LS is characterized by sepsis often evolving after a sore throat or tonsillitis and then complicated by various septic emboli and thrombosis of the internal jugular vein. Symptoms include sepsis, pain, and/or swelling in the throat or neck, as well as respiratory symptoms. Laboratory findings show elevated infectious parameters and radiological findings show thrombosis of the internal jugular vein and emboli in the lungs or other organs. The syndrome is often associated with an infection with Fusobacterium necrophorum. We found a total of 137 cases of LS, of which 47 were infected with F. necrophorum and others with Staphylococcus and Streptococcus. Complications of this rare but severe disease included osteomyelitis, meningitis, and acute respiratory distress syndrome. Mortality was extremely high in the pre-antibiotic era but has diminished with the advent of antibiotics. This review showed a mortality rate of only 2% of which none of the cases involved fusobacteria. Duration of treatment varied; a 4-6-week course of carbapenem or piperacillin/tazobactam in combination with metronidazole was optimum. Other treatment options included anticoagulants in 46% of cases, which is unwarrantedly high, as to date, no evidence of the positive effects of anticoagulants in LS exists. Only two cases had ligation of the internal jugular vein performed. This review confirms the rare, but severe aspects of LS. Mortality from LS in this day and age appears to be low, however the syndrome is difficult to recognize, and still requires the full attention of the clinician.
