BACKGROUND AND PURPOSE The objective of this study was to describe the occurrence of hemorrhagic transformation (HT) among children with arterial ischemic stroke within 30 days after symptom onset and to describe clinical factors associated with HT. METHODS Sixty-three children aged 1 month to 18 years with arterial ischemic stroke between January 2005 and November 2008 were identified from a...

Intracranial hemorrhage is an important safety end point in clinical trials. Yet, not each intracranial hemorrhage detected by computed tomography (CT) or magnetic resonance imaging (MRI) worsens neurological symptoms and impairs outcomes. Consequently, intracranial hemorrhages after ischemic stroke and reperfusion therapy are classified by both imaging characteristics and the association with ...

Chickens were intranasally inoculated with Chilean H7N3 avian influenza (AI) viruses of low pathogenicity (LP) (H7N3/LP), high pathogenicity (HP) (H7N3/HP), and a laboratory derivative (02-AI-15-#9) (H7N3/14D) from the LPAI virus to determine pathobiologic effects. All chickens inoculated with H7N3/HP AI virus became infected and abruptly died 2 or 3 days postinoculation, but a few showed moder...

BACKGROUND In this report, we present an interesting case of a patient with Rumpel-Leede phenomenon, a rare occurrence that can result in significant delays in medical treatment. This phenomenon is characterized by the presence of a petechial rash that results from acute dermal capillary rupture. In our patient, it occurred secondary to raised pressure in the dermal vessels caused by repeated i...

We present a 3-year-old female born of a consanguineous marriage with the complaints of high-grade fever, petechial spots, abdominal distension, and lymphadenopathy for 20 days. She had pallor, hypopigmented hairs, petechial rashes, and palpable lymph nodes (up to 1 cm) in the bilateral inguinal and cervical region. Systemic examination revealed hepatosplenomegaly. Her hematological profile was...

Hemotrophic mycoplasmas (HM) are highly specialized red blood cell parasites that cause infectious anemia in a variety of mammals, including humans. To date, no in vitro cultivation systems for HM have been available, resulting in relatively little information about the pathogenesis of HM infection. In pigs, Mycoplasma suis-induced infectious anemia is associated with hemorrhagic diathesis, and...

Nucleotide sequencing and phylogenetic analysis of Brazilian bovine viral diarrhea virus (BVDV) field isolates identified four viruses belonging to the genotype 2. Comparison of 5' UTR sequences from these isolates to those of North American BVDV type 2 revealed genomic variations that correlated with the geographic origins of the isolates. Two of the Brazilian type 2 viruses were isolated from...

Introduction: To determine common clinical symptoms, admission length, and treatment outcomes of infants with Immune Thrombocytopenic Purpura. Method: analysis of 132 infants with Immune Thrombocytopenic Purpura admitted to the emergency and hematology ward of Dr. Sheikh Hospital, with reference to age, gender, immunization history (preceding six weeks), presenting clinical features, treatment...

PURPOSE We investigated surgical results of staple line coverage with a polyglycolic acid sheet plus pleural abrasion by thoracoscopic surgery for treating primary spontaneous pneumothorax in young patients. METHODS Forty-seven patients younger than 40 years underwent 48 thoracoscopic surgical procedures for spontaneous pneumothorax at the Division of Thoracic Surgery, Department of Surgery, ...
