Case Reports
[Neurotoxicity during induction treatment of childhood acute lymphoblastic leukaemia--two case reports].
During chemotherapy of acute lymphoblastic leukaemia (ALL), children sometimes exhibit neurological disturbances. Chemiotherapeutic regimens include methotrexate, administered either intravenously or via intrathecal route. Although multiple drugs are used in addition to methotrexate, the acute neurotoxicity reported in patients is usually attributed to methotrexate. The acute neurotoxicity usually results in stroke-like symptoms such as aphasia, weakness, sensory deficits, ataxia and seizures. ⋯ The neurotoxicity in patients with ALL can be combined with significant structural changes of the brain, but also morphological changes can be absent. Several questions concerning aetiology and treatment of neurological events are raised.

Comparative Study
[Bernard Organ Failure Score in estimation of most severe forms of acute pancreatitis].
Despite intensive research, efforts and clinical investigations on pathogenesis of acute pancreatitis (AP) and system morbidity during the illness onset, mortality is still very high in the group of severe forms. A significantly high number of patients show moderate, self-limited forms of illness, with a minimal degree of systemic or local complications, with full recovery. However, some of them have a severe form, followed by a high percent of morbidity and mortality, and system organ failure. The distinction between mild and severe forms of AP within 24-48 hours of hospital admission is very important for the treatment of these patients. The usage of multifactorial scoring systems holds a lot of promise, reaching reliability in the disease severity estimation of approximately 70-80%. ⋯ The concept of the BOFS score has more advantages than the APACHE II score in the patients with severe forms of AP with organ dysfunction.

The fracture of the external condyle is the most common fracture of the distal end of the humerus. This is an intraarticular fracture, which, if not properly treated, can cause serious complications, difficult to treat. ⋯ The initial width of the fracture crack is important for the evaluation of the fracture stability, the evaluation of the risk for the creation of secondary dislocations and for the choice of treatment. The upper limit of the fracture crack width which influenced the selection of the method of treatment was 2.5 mm.

Exentheresis pelvis totalis due to locally advanced pelvic malignancies is an extensive surgical procedure. The operation is commonly associated with anticipated perioperative haemorrhage requiring a large volume of haemoproducts. Sometimes, the intervention can result in unexpected massive and uncontrolled haemorrhage that is frequently a combination of surgical and coagulopathic bleeding. Attempts to arrest massive bleeding by conventional means may fail. ⋯ RFVIIa can be a treatment option in patients suffering from intractable coagulopathic bleeding when standard therapy has failed.

Inflammatory abdominal aortic aneurysm accounts for 5% to 10% of all cases of abdominal aortic aneurysm and differs from typical atherosclerotic abdominal aortic aneurysm in many important ways. Although both inflammatory and atherosclerotic abdominal aortic aneurysms most commonly affect the infrarenal portion of the abdominal aorta, patients with the inflammatory variant are younger and usually symptomatic, chiefly from back or abdominal pain. Unlike patients with atherosclerotic abdominal aortic aneurysm, most with the inflammatoryvariant have an elevated erythrocyte sedimentation rate or abnormalities of other serum inflammatory markers. Computed tomography and magnetic resonance imaging are both sensitive for demonstrating the cuff of soft tissue inflammation surrounding the aneurysm that is characteristic of inflammatory abdominal aortic aneurysm. Inflammatory abdominal aortic aneurysm can be primarily infected by degenaration of an infected artery (in less than 1% of cases), or can become secondary infected in the already existing aneurysm. Seconadary infection of the pre-existing aneurysm has big inffluence on treatment choice, but is also rare. Clinically non-symptomatic infection, also known as bacterial collonisation, can be very frequent, regarding a greatly increased number of positive intraoperative findings (10-15%). Prolonged intravascular catheterization, vascular grafting, repeated punctures with large bore needles, and decreased immune defence mechanism make uraemic patients undergoing haemodialysis more likely to develop Staphylococcus aureus bacteraemia and its complications. ⋯ There were no postoperative complications, and the final outcome was fully satisfactory. Control CT scans after 3, 6 and 12 months were regular, with signs of regression fibrosis of the retroperitoneum.,
