1/14. Varicella arthritis diagnosed by polymerase chain reaction.We report a 2-year-old girl who developed acute arthritis of the left knee 4 days after the onset of a typical varicella infection. She was first thought to have pyogenic arthritis caused by staphylococcus aureus. Accordingly, oxacillin was administered upon hospitalization. On the third day after hospitalization, bacterial cultures of the synovial fluid and blood showed no growth and oxacillin was discontinued. Although a viral culture of the synovial fluid for varicella-zoster virus (VZV) was negative, varicella dna was identified by means of polymerase chain reaction (PCR) with VZV-specific primers. The patient recovered spontaneously. To differentiate this condition from septic arthritis is important. PCR is a sensitive technique that can demonstrate the presence of VZV dna in synovial fluid, even if viral cultures are negative.- - - - - - - - - - ranking = 1keywords = varicella (Clic here for more details about this article) |
2/14. Chicken pox infection (varicella zoster virus) and acute monoarthritis: evidence against a direct viral mechanism.A 9 year old boy developed acute monoarthritis of the left knee concurrent with the appearance of a varicella zoster virus (VZV) rash. Repeated VZV dna hybridisation of the cells within the synovial fluid and synovial membrane failed to show any evidence of intracellular virus. Virus was isolated from synovial fluid 24 hours after the start of clinical infection but not later. These findings suggest that the mechanism of the arthritis is not due to viral replication inside the swollen joint.- - - - - - - - - - ranking = 1.6666666666667keywords = varicella (Clic here for more details about this article) |
3/14. Septic arthritis of the elbow after chickenpox.Musculoskeletal complications following chickenpox are rare among immunologically normal children. Septic arthritis after varicella is caused by group A streptococcus and affects the knee most frequently. We present a case of septic arthritis of the elbow caused by staphylococcus aureus. We review the English language literature on septic arthritis complicating chickenpox. We conclude that diagnosis and treatment should be carried out according to guidelines on de novo septic arthritis including the early use of magnetic resonance imaging.- - - - - - - - - - ranking = 16.554720909513keywords = chickenpox, varicella (Clic here for more details about this article) |
4/14. Varicella-associated arthritis occurring before the exanthem. Case report and literature review.Varicella-associated arthritis represents an uncommon complication of varicella in children. In 20 previously reported cases, three were documented to be bacterial in origin. Viral isolation from synovial fluid was attempted in seven others, and varicella was isolated in just two. In all previous case reports, the arthritis occurred after or coincident with the onset of varicella. The current case is one in which joint involvement preceded the clinical onset of varicella. Clinicians should be alert to the possibility that varicella may manifest as an acute arthritis, even in the absence of the typical exanthem.- - - - - - - - - - ranking = 1.6666666666667keywords = varicella (Clic here for more details about this article) |
5/14. A transient granulocyte killing defect secondary to a varicella infection.A varicella infection in a previously healthy young girl was complicated by bacterial sepsis, arthritis, and osteomyelitis in multiple locations. This secondary complication caused by staphylococcus aureus was associated with a transient defect in granulocyte function and an alteration in the representation of CD4 and CD8 positive lymphocyte subpopulation. The mechanism responsible for secondary bacterial infections following varicella may be due to transient defects in granulocyte function.- - - - - - - - - - ranking = 2keywords = varicella (Clic here for more details about this article) |
6/14. A study of synovial fluid and cytology in arthritis associated with herpes zoster.A case of herpes zoster complicated by acute arthritis with effusions is described. The white cell count in the synovial fluid was low, with a predominance of neutrophils. The synovium showed superficial deposits of fibrin, slight intimal hyperplasia, and subintimal polymorph infiltration. Varicella virus was not detected by culture or electron microscopy, but varicella antigen was demonstrated in the cytoplasm of macrophages in the effusion. Other findings did not determine whether the antigen had appeared in the joint from circulating immune complexes, or following synovial phagocytosis or proliferation of virus.- - - - - - - - - - ranking = 0.33333333333333keywords = varicella (Clic here for more details about this article) |
7/14. pericarditis with pericardial effusion complicating chickenpox.A girl with chickenpox is presented. She developed arthritis, pericarditis with pericardial effusion and meningism during the course of her illness. pericarditis is an unusual complication of this disease, and in this instance was associated with characteristic electrocardiographic changes.

8/14. Varicella arthritis. Report of a case.A rare case of varicella with bilateral acute arthritis of the knee is described. Clinical features and laboratory results of the patient are briefly compared with those of other sixteen cases previously published. The study of immune response shows a decrease of helper T cells (OKT4 ) and an increase of suppressor/cytotoxic T cells (OKT8 ) with a normal response of lymphocytes to PHA.- - - - - - - - - - ranking = 0.33333333333333keywords = varicella (Clic here for more details about this article) |
9/14. Varicella arthritis.Varicella arthritis is an acute self-limited arthritis, occurring in close temporal association with clinical varicella, which is usually monarthric, involving the knee of a prepubertal girl. We have reported a case of varicella arthritis and summarized the clinical and laboratory findings of our case and the cases reported in the English literature. It is important to differentiate this condition from septic arthritis.- - - - - - - - - - ranking = 0.66666666666667keywords = varicella (Clic here for more details about this article) |
10/14. Varicella arthritis in a child.A 2 1/2-year-old girl developed arthritis in a metatarsophalangeal joint concomitantly with varicella. As she recovered within 2 days without antimicrobial treatment, it was considered that the arthritis was directly due to the viral infection. The importance of differentiating viral arthritis from septic arthritis, a well-known complication of varicella, is stressed.- - - - - - - - - - ranking = 0.66666666666667keywords = varicella (Clic here for more details about this article) |
