A Technical Problem in Diagnosis Clarity of Solitary Spinal Cord Neurofibroma in an Eleven-month-old Boy.

Spinal neurofibroma is one of the rarest of the neoplasms involving the spinal cord or roots and occurs much less often than neurinoma, meningioma or glioma. The sixth pediatric case of solitary intramedullary tumor was described in 2013, according to B. Eljebbouri et al. We present a rare, difficult to diagnose and may-be the seventh pediatric case of solitary neurofibroma of the cauda equine in an 11-month-old infant. The patient underwent a laminectomy of T12, L1, L2 and L3, extirpation of intradural, intramedullary and extramedullary spinal cord tumor. The patient is fully recovered for 5 years of monitoring. Although rare, spinal neurofibromas in children should be diagnostically considered and radically treated for a favorable outcome.

Endoscopic diagnosis of intramural hematoma in the colon sigmoideum in a child with high titer inhibitory hemophilia A.

Lower gastrointestinal bleeding is a rare condition in childhood pathology. The incidence of this disorder in the general population of Bulgarian children is unknown. We report a case of a 7-year-old child with diagnosed hemophilia A and high titer of factor VIII inhibitor; the patient was admitted into the Department of Pediatrics and Medical Genetics for rectorrhagia after falling onto his buttocks while playing. Colonoscopy showed submucosal hematoma 25 cm from the anocutaneous line occluding the intestinal lumen with a lesion of the overlying mucosa as long as 20 mm. If a patient presents with rectorrhagia, timely and carefully planned colonoscopy could identify the source of bleeding, determine the severity of bleeding and the size of hematoma, and assess the need for surgical intervention. The reported case supports the modern view that patients with inhibitor hemophilia should not be denied interventional procedure or surgical intervention for fear of uncontrolled bleeding.

Pseudomembranous necrotizing tracheobronchitis caused by Aspergillus spp--contribution of one case with acute myeloid leukemia.

Acute tracheobronchitis is a rare clinical manifestation of respiratory tract invasive aspergillosis, sporadically reported in patients with hematological malignancies against the background of conventional chemotherapy. The authors report on a case of pseudomembranous necrotizing form of histologically proven tracheobronchitis, caused by Aspergillus spp in the time of induction chemotherapy in a patient with acute myeloid leukemia. The clinical evolution is gradual: from mild non-specific manifestations of acute tracheobronchitis against the background of a prolonged fever unaffected by antibiotic therapy to the onset of severe acute respiratory insufficiency and unilateral bronchial obstruction syndrome. Multiple spontaneous expectoration of a part of the bronchial wall was observed in which Aspergillus spp hyphae were histologically proven. Tracheobronchoscopy verified nearly complete obturation of the left main bronchus with thick mucous plugs. Lethal outcome from the infection occurred at the stage of hematological remission because of a massive hemoptysis. The diagnostic methods, therapeutic possibilities and differential diagnosis of this rare infectious complication in immunocompromised patients are discussed.

Interleukin-6, interleukin-8, interleukin-10, and C-reactive protein in febrile neutropenia in children with malignant diseases.

AIM: To compare serum levels of interleukin-6, interleukin-8 and interleukin-10 in bacteremic and non-bacteremic episodes of febrile neutropenia in children with malignant diseases, and determine their changes and correlation with C-reactive protein (CRP). MATERIAL AND METHODS: Between January 2003 and June 2004, we examined 41 episodes of febrile neutropenia in 24 children with malignant diseases who were receiving polychemotherapy. C-reactive protein was measured at the onset of febrile episodes and on days 3 and 5 from beginning of therapy. The soluble interleukins-6, -8, and -10 were determined in the serum using enzyme bound immunosorbent analysis at the onset of fever and at 24 and 72 hours after initiation of an empiric antibiotic therapy. RESULTS: The CRP baseline levels differentiated the patients with unexplained fever from those with local infection but did not differentiate them from those with bacteremia. Interleukin-8 at 24 hours differentiated bacteremic from non-bacteremic episodes (P < 0.05) and at a cut-off value of 130 pg/ml it had a sensitivity of 72% and a specificity of 84% to differentiate bacteremia. Interleukin-10 at 24 hours yielded higher values in Gram (-) bacteremia in comparison with the non-bacteremic episodes (P < 0.001) and Gram (+) bacteremia (P < 0.05). Interleukin-6 at 24 hours had significantly higher values in febrile episodes of more than 3 days duration (P < 0.05). CONCLUSIONS: Interleukin-8 could differentiate in the first 24 hours bacteremic from non-bacteremic episodes in febrile neutropenia, while interleukin-10 is perhaps a more accurate marker for Gram (-) bacteremia.
