Rheumatic fever (RF) is an inflammatory disease caused by autoimmune response to a preceding group A streptococcal infection. Mean platelet volume (MPV) reflects the platelet size and the rate of platelet production in bone marrow, and it may be used as an indicator of platelet activation and severity of inflammation. Fifty-three consecutive patients diagnosed with acute rheumatic carditis and 53 control subjects were enrolled into this study. Leukocyte and platelet counts were significantly higher in patients with acute carditis before treatment compared with controls, whereas MPV and platelet distribution width (PDW) values were not significantly different between groups. Platelet counts, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) values were decreased significantly in patients with RF after treatment. There was not a significant difference in terms of platelet count between the controls and the patient group after treatment. ESR was found to be correlated with CRP in patients before and after treatment. In conclusion, the results of our study showed that MPV and PDW levels do not change during acute rheumatic carditis before and after treatment.
Brucella infections have a wide spectrum of symptoms especially in children, making the diagnosis a complicated process. The gold standard for the final diagnosis for brucellosis is to identify the Brucella spp. isolated from blood or bone marrow cultures. The main purpose of this work was to evaluate the factors affecting the isolation of Brucella spp. from blood cultures. In our study, the ratio of fever, presence of hepatomegaly, and splenomegaly were found to be higher in the bacteremic group. In addition, C-reactive protein levels and liver function enzymes were found to be higher in the bacteremic group. In our opinion, while evaluating the febrile child with suspected Brucella infection, we highly recommend sampling blood cultures regardless of the history of previous antimicrobial therapy and duration of the symptoms.
Acute generalized exanthematous pustulosis (AGEP) is a rare cutaneous rash characterized by the abrupt onset of a generalized pustular rash often accompanied by fever. There is a history of drug use in 90% of the cases. Here we have reported a 15-year-old male patient with sickle cell anemia who developed AGEP after the use of ceftriaxone. Our patient was hospitalized because of vaso-occlusive crisis and on the third day of ceftriaxone treatment, erythematous pustular lesions accompanied with fever were observed on the body and extremities. Resolution of symptoms followed discontinuation of ceftriaxone. Sensitivity to ceftriaxone was shown with a patch test. The AGEP was considered due to clinical and histopathological findings. This is the first pediatric case of AGEP due to ceftriaxone.
Eosinophilic cellulitis (Wells’ syndrome) is an uncommon condition of unknown etiology. Wells’ syndrome is usually seen in adulthood but very rare in childhood. Although pathogenesis of the disease is not very clear, it is a hypersensitivity reaction developing against a variety of exogenous and endogenous antigenic stimuli. Paraphenylenediamine is a strong allergen frequently used as a temporary henna tattoo, which makes the color darker. Here, a 9-year-old male patient with Wells’ syndrome is presented, which developed following a temporary henna tattoo and shown by the patch test sensitivity to paraphenylenediamine.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
