    ABSTRACT: We compared spectrophotometric analysis of the umbilical cords of infants with meconium aspiration syndrome (MAS) or with meconium-stained amniotic fluid (MSAF) and healthy infants. In a prospective study, 15 infants with MAS and 37 infants with MSAF were enrolled. Twenty healthy infants formed a control group. The absorption peak of umbilical cords with meconium was significantly higher in the infants with MAS or MSAF than in controls. Spectrophotometric analysis of the umbilical cords with meconium may be useful to identify developed neonates with MAS or MSAF.

    ABSTRACT: Immune thrombocytopenic purpura is an acute, generally considered a self-limiting benign disorder with a 60%-80% change of spontaneous recovery occurring usually within a few months after onset. Intracranial hemorrhage is a rare but life-threatening complication of childhood immune thrombocytopenic purpura. We report a 4-year-old girl who admitted with headache, vomiting, bleeding from noise and bruises on the extremities. Her neurological examination was normal. Based on laboratory finding she was diagnosed immune thrombocytopenic purpura and intracranial hemorrhage. We suggest that cranial imaging should be perform in patients with immune thrombocytopenic purpura admitted with bleeding symptoms, vomiting and headache even if they had no abnormal neurological signs.

    ABSTRACT: Varicella zoster virus causes varicella which is a common disease. Generally it is self-limiting, and treatment is often unnecessary, but severe or life-threatening complications are rarely seen. We report a case of fulminant varicella complicating with purpura fulminans, hepatitis, and probable rhabdomyolysis in a previously healthy child.

    ABSTRACT: Vasculitis in childhood is a result of a spectrum of causes ranging from idiopathic conditions with primary vessel inflammation to syndromes after exposure to recognized antigenic triggers, such as infectious agents and drugs causing hypersensitivity reactions. Henoch-Schönlein purpura (HSP) is the most common vasculitis of childhood. Although there is often a history of a recent or simultaneous upper respiratory tract infection, no consistent causative organism is found. We report an 11-year old boy with HSP and brucellosis and we speculated that brucellosis was the trigger agent for HSP (Ref. 13). Keywords: brucellosis, trigger agent, Henoch-Schönlein purpura, vasculitis, infectious agents, drug, hypersensitivity reactions, primary vessel inflammation.

    ABSTRACT: Febrile seizures (FS) are the most common cause of seizures in children. The exact etiopathogenesis is unknown but involves factors like genetic predisposition and alterations in the levels of neurotransmitters and some trace elements. The study includes 48 consecutive children with FS, and 55 healthy age matched control subjects. Calcium, magnesium and potassium concentrations in the febrile study group were lower than in the control group (p<0.05). Iron and Gallium levels in the study group were lower than in the control group (p<0.01). Serum Selenium (p<0.001), Zinc (p<0.001) and Strontium (p0.05). The aim of the present prospective analytical case-control study was to determine whether there was any change in element levels in children with FS (Ref. 33).

    ABSTRACT: Brucellosis is an endemic disease in many areas throughout the world. Central nervous system involvement is a serious complication of brucellosis with a ratio of 4-11% of all patients. Aim: to describe our experience in diagnosis, treatment, and outcome of 25 pediatric patients with neurobrucellosis. This study included a review of medical records of patients who were diagnosed with neurobrucellosis between March 2001 and March 2009. Patients who had both clinical findings consistent with neurobrucellosis and positive microbiologic/serologic examinations of CSF with abnormal CSF findings were enrolled in the study. The study included 25 patients between 1 and 15 years of age (mean 8.8 years), while 15 were males and 10 were females. Most of the patients (52 %) were in the age group of 5-9 years with male predominance. The distribution of cases showed density in June and February. The most commonly presented complaints were headache, fever and sweating while the most commonly observed findings were fever and meningeal irritation signs. All patients had positive cerebrospinal fluid agglutination test for brucellosis. Four different regimens were used based on ceftriaxone, doxycycline, cotrimoxasole, streptomycin, and rifampicin. One patient died, three patients were discharged with sequel, and the remaining patients (84 %) were discharged with full recovery. Clinicians, especially those providing health services in endemic areas like Turkey, should keep in mind that neurobrucellosis can be involved in patients with unexplained symptoms like memory impairment or in patients diagnosed with meningitis (Tab. 5, Fig, 2, Ref. 39).

    ABSTRACT: In Henoch-Schönlein purpura (HSP), involvement of the ileum and ascending colon with vasculitis can mimic appendicitis and cause unnecessary appendicectomy. A 13-year-old boy presented with signs of HSP and abdominal pain. He was treated with prednisolone (2 mg/kg/day) for 10 days, but there was no improvement. At laparotomy he had acute suppurative appendicitis. A 12-year-old girl presented with HSP associated with abdominal pain and bloody diarrhoea and at laparotomy was also found to have suppurative appendicitis. Both patients had vasculitic areas in the ileum. In HSP, although suppurative appendicitis is rare, it should always be considered and appropriate investigations, including ultrasonography, undertaken.

    ABSTRACT: Brucellosis is a multisystem disease with a broad spectrum of clinical manifestations; hematological abnormalities ranging from fulminant as of disseminated intravascular coagulation (DIC) to anaemia, leucopoenia, thrombocytopenia, and clotting disorders. In this report, we present DIC in a case of brucellosis because of rare presentation. A 3-year-old boy was admitted with the complaints of continuous fever, vomiting, abdominal pain, and bruise on leg. He looked pale and his physical examination revealed purpuric skin lesions on both legs. A mild hepatosplenomegaly was noted on palpation. Laboratory tests showed hematocrit 21%, hemoglobin 7 g/dL, platelet count 20,000/mm(3), prothrombin time 19 seconds, activated partial thromboplastin time 48 seconds, plasma fibrinogen level 20 mg/dL, and D-dimer 8 µg/mL. Serum antibrucella titration agglutination test was found to be 1 of 1280 positive. Blood cultures performed on specimens obtained at the time of admission yielded Brucella melitensis. The clinical and laboratory findings were consistent with DIC.

    ABSTRACT: Hematologic abnormalities of mild anemia and leucopenia have been frequently associated with acute brucellosis, but thrombocytopenia are less frequently seen. In the present study, we documented 5 (2.6%) isolated thrombocytopenic patients with the manifestations of brucellosis observed during the course of active infection. Five (2.6%) patients, 4 boys and 1 girl, with ages ranging from 2 to 14 years, had isolated thrombocytopenic at diagnosis. In 5 (2.6%) patients, platelet counts ranged from 39,000 to 120,000/mm(3). Tube agglutination tests for brucellosis were positive for all patients (1/160-1/1280). All patients recovered completely, and their thrombocytopenia returned to normal by 2 to 4 weeks after antibiotic treatment of brucellosis. In our study, we present 5 patients with Brucella-induced thrombocytopenia mimicking idiopathic thrombocytopenic purpura to emphasize the isolated thrombocytopenia and the resolution of thrombocyte counts following treatment of brucellosis.

    ABSTRACT: Celiac disease (CD) is a disease of the small intestine caused by an immune response to ingested gluten. Idiopathic thrombocytopenic purpura (ITP) is a common acquired bleeding disorder of childhood. It may follow a viral infection or immunization and is caused by an inappropriate response of the immune system. Autoimmune thyroiditis (AT) is a disease that occurs due to autoimmune mechanisms. Celiac disease associated with autoimmune thyroid disease is well known, but the association of CD, autoimmune thyroid disease, and ITP has been reported very rarely in the literature. In the current report, we have presented a case with CD, AT, and acute ITP, because this association is rarely seen, and to emphasize that CD and AT should be kept in mind in patients with ITP.

    ABSTRACT: In the current study, clinical and laboratory findings and treatment modalities of children with acute and chronic immune thrombocytopenic purpura (ITP) were evaluated retrospectively. Our purpose was to determine clinical outcome of children with ITP and their responses to different treatment regimes. Total of 260 children with ITP were enrolled in the study. The mean age of patients was 76.8 ± 48.1 months. The therapy responses of high-dose methylprednisolone (HDMP; n = 134), standard dose methylprednisolone (n = 32), and intravenous immunoglobulin (IVIG; n = 15) treatments were similar. Two (0.8%) of the 260 ITP patients had intracranial bleeding. None of the patients died due to hemorrhage. Of all the patients with ITP, 191 (73.5%) completely resolved within 6 months after initiation of the disease and therefore they were diagnosed as acute ITP; 69 patients (26.5%) had progressed into chronic ITP. The therapy responses of HDMP, standard dose methylprednisolone, and IVIG treatments are similar.

    ABSTRACT: This report highlights a rare presentation of vitamin B(12) deficiency (concurrent psychotic disorder, seizures and hypertension). A 16-year-old girl presented with nervousness that had been persisting for 2 weeks. She had stopped eating and there was decreased self-care and she could not walk and sleep. Two days prior to admission, generalized tonic-clonic convulsions were noted. On physical examination, vital signs were normal, except for hypertension (150/100 mm Hg). She did not respond to conversation; she could not answer the questions. Mood was depressive and hallucinations were noted. Laboratory analyses were normal, except for a low vitamin B(12) level (<150 pg mL(-1)). The patient was not given any treatment of hypertension, psychosis or seizures, except vitamin B(12) injections. After that, she showed improvement within 1 week. In the 7 days of hospitalization, the arterial blood pressure returned to normal, psychotic symptoms were resolved, the visual hallucinations and the depressive mood subsided, and she could eat and speak clearly. No hypertension or convulsions have been detected on the control examinations, and she has now been followed-up without any symptoms or findings. In conclusion, with this report we emphasized that psychosis, seizures and hypertension can be a rare manifestation of vitamin B(12) deficiency, which is reversible with therapy and serum vitamin B(12) level should be checked in patients who do not have an obvious cause for psychosis, seizures or hypertension.

    ABSTRACT: Cerebral venous sinus thrombosis (CVST) is an uncommon disease in childhood. In the largest study carried out so far, the incidence was 0.67 case per 100,000 children per year. A number of etiologies and risk factors have been so far identified for CVST in childhood, including head trauma, local and systemic infectious diseases, malignancies, and autoimmune diseases. Celiac disease (CD) is a disease of the small intestine caused by an immune response to ingested gluten. Epilepsy, bilateral occipital calcification, cerebellar ataxia, degenerative central nervous system disease, peripheric neuropathy, myopathy, and rarely stroke were defined as neurologic disorders. In this presentation, we report 2 cases (16-year-old boy and 2-year-old boy) with CD and CVST. We emphasized that CD can be investigated in patients with CVST even with the absence of gastrointestinal symptoms. Finally, we suggest that algorithm of CVST can be involved in the investigation of CD.
