Generalized Petechial Rashes in Children During a Parvovirus B19 Outbreak
ABSTRACT Human parvovirus B19 infection is associated not only with erythema infectiosum (fifth disease) but also, rarely, with purpuric or petechial rashes. Most reports of these atypical rashes describe sporadic cases with skin lesions that have distinctively focal distributions. During a community outbreak of fifth disease, we investigated a cluster of illnesses in children with generalized petechial rashes to determine whether parvovirus was the causative agent and, if so, to describe more fully the clinical spectrum of petechial rashes that are associated with this virus.
Systematic evaluation was conducted by general pediatricians of children with petechial rashes for evidence of acute parvovirus infection.
During the outbreak, acute parvovirus infection was confirmed in 13 (76%) of 17 children who were evaluated for petechial rash. Confirmed case patients typically had mild constitutional symptoms, and most (11 [85%] of 13) had fever. Petechiae were typically dense and widely distributed; sometimes accentuated in the distal extremities, axillae, or groin; and usually absent from the head/neck. Most case patients had leukopenia, and several had thrombocytopenia. Parvovirus immunoglobulin M was detected in 8 (73%) of 11 acute-phase serum specimens, and immunoglobulin G was detectable only in convalescent specimens. Parvovirus DNA was detected in all 7 tested serum specimens, including 2 acute-phase specimens that were immunoglobulin M-negative. All case patients had brief, uncomplicated illnesses, but 6 were briefly hospitalized and 1 underwent a bone marrow examination. Two case patients developed erythema infectiosum during convalescence.
During an outbreak of fifth disease, parvovirus proved to be a common cause of petechial rash in children, and this rash was typically more generalized than described in case reports. Associated clinical features, hematologic abnormalities, and serologic test results are consistent with a viremia-associated illness that is distinct from and occasionally followed by erythema infectiosum.

ABSTRACT: Hand, Foot, and Mouth disease (HFMD) is classically defined as a childhood fever accompanied by a rash with vesicles or erosions of the oral mucosa, hands, feet and sometimes the buttocks. Severe neurological complications are associated with enterovirus 71 outbreaks in Asia. Recently, it has been suggested that HFMD is related to coxsackie virus A6 (CV-A6) when there is an atypical skin rash. To determine the dermatological pattern of HFMD and to identify the virus serotypes associated with a specific dermatological pattern. A prospective, cross-sectional study was conducted in seven pediatric dermatology units in France from March 2010 to February 2012. All children with clinically suspected diagnosis of HFMD were included. Clinical data were collected and swabs from the nasopharynx and vesicles were taken for RT-PCR and genotyping. Only children with confirmed HFMD - defined by clinical diagnosis of HFMD and positive enterovirus PCR results - were included for analysis. One hundred and four (104) children consulted for suspected HFMD, including 89 (mean age 25.7 months; sex ratio M/F 1.54) with confirmed HFMD. Seventy-eight (87.6%) had skin lesions on sites other than hand feet and mouth (HFM). Thirty-seven (41.5%) had five or more anatomical sites involved (HFM, buttocks, legs, arms, and trunk) considered as widespread exanthema. Widespread vesicular exanthema was observed with both CV-A6 and CV-A16. Peri-oral rash was associated with CV-A6 (p<0.001). HFMD has a clinical spectrum ranging from classical to generalized vesicular exanthema. Generalized and atypical exanthema were observed with both CV-A6 and CV-A16 infections. CV-A6 is associated with peri-oral rash.The Pediatric Infectious Disease Journal 01/2014; 33(4). DOI:10.1097/INF.0000000000000120 · 3.14 Impact Factor

ABSTRACT: Petechiae and purpura are among the most alarming findings a pediatrician will commonly observe in the office. Severity of illness can range from a temper tantrum, to common viral infections, to the most deadly infections and diseases. To avoid many of the pitfalls in diagnosis, practitioners will need to be thorough in history taking, assessing fever and immunization status, and physical examination. In addition, a few simple laboratory tests will usually be needed and possibly a manual differential. [Pediatr Ann. 2014;43(8):297-303.].Pediatric Annals 08/2014; 43(8):297-303.

ABSTRACT: Parvovirus B19 can cause petechial rashes in the acute phase of illness as well as erythema infectiosum (fifth disease) during convalescence. This petechial rash is often called "gloves and socks" syndrome because of the typical distribution of the eruption. However, involvement of other sites (e.g., intertriginous area) and generalized involvement have been recently recognized. We report here a patient with parvovirus-associated petechiae and cephalhematoma. The patient was a previously healthy 10-year-old boy. There was a family history of fatal bleeding; his sister died of intracranial bleeding with an uncertain cause at the age of 5 months. The patient was admitted to our hospital because of sudden onset of cephalhematoma associated with fever. He reported that he had no recent head trauma but that he massaged his scalp on the day before admission. On admission, his temperature was 38.8[degree sign]C; otherwise, he was in a stable condition. Besides cephalhematoma, petechial rashes were present on his trunk and limbs. The initial laboratory tests were essentially normal, including platelet count and coagulation tests. Expanded laboratory tests were repeated to explore the etiology of his skin hemorrhage, all of which indicated that hematological disorders were unlikely. His symptoms subsided spontaneously over the next few days and he was discharged uneventfully. Anti-parvovirus IgM titer was elevated during hospitalization and typical erythema infectiosum was seen approximately 1 week after discharge. During 6 months follow-up, he remained stable without recurrence of a hemorrhagic episode. Finally, we concluded that his cephalhematoma was responsible for acute parvoviral infection. This is believed to be the first report describing a possible association between parvovirus B19 infection and cephalhematoma. Parvovirus B19 infection should be considered in the differential diagnosis of children who present with unexplained hemorrhage such as cephalhematoma or petechiae.BMC Infectious Diseases 10/2013; 13(1):465.
