[Focal nodular hyperplasia of the liver in a young female]. / Ogniskowa hiperplazja watroby u mlodej kobiety.

Focal nodular hyperplasia (FNH) of the liver is a lesion characterized by a well circumscribed region of hyperplastic liver tissue with stellate fibrosis. The pathogenesis of FNH is unknown but various authors consider that this lesion may be a response to a preexisting vascular abnormality. A 27-year-old woman was referred because of large liver lesion detected by ultrasound abdominal examination. Doppler ultrasound, computed tomography and magnetic resonance suggested this was FNH. The patient was conducted to resection of the tumor because of size of the tumor and presence of clinical signs and symptoms. Pathological examination of the surgical resection confirmed diagnosis of FNH. Follow-up after 1 and 2 years showed that the patient remained well but she complained of general weakness and we found unexplained elevation of GGT. Liver biopsy was performed 1 year after resection of the tumor and histopathological examination showed only minimal reactive changes.

[Staphylococcus aureus sepsis--still life threatening disease]. / Posocznica gronkowcowa--choroba nadal zagrazajaca zyciu.

We report an analysis of clinical course of 18 patients presenting with Staphylococcus aureus sepsis. Community acquired infection was caused by Methicillin susceptible S. aureus (MSSA) in 11 patients. MSSA in 3 and Methicillin Resistant S. aureus strains (MRSA) in 4 patients, were the etiologic factor in 7 patients with nosocomial infection. From anamnestic data patients presented with: elevated body temperature--18/18, arthralgia and myalgia--9/18, headache--8/18, nausea--6/18, chills--2/18. Physical examination on admission revealed: meningismus--12/18, hepatomegaly--11/18, purulent and haemorrhagic skin lesions--7/18 and impaired neurological status (Glasgow Coma Scale < or = 12)--6/18. The mean APACHE III score, calculated from data collected at diagnosis of sepsis was 47 (7-114). Several complications had been observed: endocarditis--10, purulent meningitis--5, focal CNS lesions--5, pneumonia--8, pulmonary abscess--3, hydrothorax--1, abscesses of the spleen--5, renum--4, osteomyelitis--2. 11/18 patients required ICU treatment. Ventilator assistance of respiration was necessary in 7/18. Acute thrombocytopenia (< 100,000/ml) was diagnosed in 60%. In 5 patients suppurative meningitis had been diagnosed with a mean pleocytosis-837 (173-1898) microL. The results of treatment were satisfactory in 11 patients, 3 patients required further surgical treatment (2--cardiosurgery, 1--orthopedic surgery), 4 patients died. Infection caused by community acquired MSSA strains had been characterized by severe clinical course with increased incidence of endocarditis, organ failure and abscess forming. We conclude that Staphylococcus aureus sepsis is still a life-threatening disease, which should be treated at centers with immediate access to imaging techniques of CNS and circulatory system as well as intensive care and cardiosurgery. Community acquired S. aureus sepsis compared with nosocomial infection is characterized by more severe clinical course and higher mortality, despite of a great susceptibility to most antibiotics of causative S. aureus strains.
