Neonatal Escherichia coli meningitis is a serious disease with high mortality and poor outcome. Ventriculitis, brain abscess and subdural empyema are frequent, with no homogeneous recommendations available for these complications. The case of a newborn infant who developed sepsis and meningitis caused by E. coli is presented. During intravenous treatment with ampicillin, cefotaxime and gentamycin in recommended doses, the patient developed severe subdural abscesses detected on MRI. After consequent antibiotic therapy over 2 months with fosfomycin, amikacin and meropenem the patient improved clinically and the abscesses regressed and disappeared without neurosurgical intervention. At the age of 6.5 months the infant is healthy and well developed. The conservative treatment of subdural abscesses complicating neonatal Escherichia coli meningitis without neurosurgical intervention is possible. The treatment of the individual case should be discussed between pediatrician and neurosurgeon.

A 56-year-old woman with aortic regurgitation (AR) developd a high fever on April 25th, 2003, followed by the sudden onset of left hemiparesis and dysarthria on May 10th, 2003. MRI and MRA showed cerebral infarction due to occlusion of the right proximal portion of the middle cerebral artery. Streptococcus was isolated from arterial blood culture at the time of admission and cardiac examination such as echocardiography revealed active infective endocarditis. Cerebral angiography on the 31st day after the onset of symptoms demonstrated a fusiform-shaped aneurysm at the occluded M2 portion of the middle cerebral artery. Despite administration of antibiotics, a small subcortical hematoma was observed in the right temporal lobe surrounding the aneurysm on the 35th day. The direct surgery of aneurysmal trapping and resection was subsequently performed to prevent rebleeding. The sylvian fissure and perianeurysmal area were strongly adherent to granulation tissue and blood clot. After exposing the aneurysm, the dilated portion of the vessel was successfully trapped and resected. Other than residual left hemiparesis, the postoperative course was uneventful. Histological examination confirmed bacterial aneurysm due to bacterial embolization originating from infective endocarditis (IE). We report a rare case having a ruptured bacterial aneurysm of the middle cerebral arterial bifurcation requiring surgery following occlusion due to bacterial embolization after sepsis and meningitis due to infective endocarditis.

A 57-year-old man was referred to our hospital because of elevated ALP. CT and MRI scans together with abdominal angiography showed multiple masses in his abdomen and portal vein obstruction. A diagnostic laparoscopic examination revealed a tumor of 3 cm x 3 cm near the portal vein and para-aortic lymphadenopathy. Histopathological examination of the tumor showed abnormal follicles with poorly formed germinal centers, scattered large spindle cells with proliferation of small lymphocytes, and hypervascular interfollicular tissue. The spindle cells were positive for follicular dendritic cell markers CD21, CD35, and epithelial membrane antigen. The diagnosis was made of a follicular dendritic cell (FDC) tumor in Castleman's disease (CD) of the hyaline-vascular type. Although the portal vein was obstructed by the FDC tumor, blood flow to the liver was retained by collateral vein. The patient did not show any response to four courses of CHOP therapy and died of obstructive jaundice, biliary tract infection and sepsis. So far, 17 cases of FDC tumor complicating CD have been reported, with a poor prognosis in all cases.

A 67-year-old man under hemodialysis treatment developed neck stiffness, fever and conscious disturbances. The patient was infected with Methicilin-resistant Staphylococcus aureus (MRSA) sepsis caused by an infection on a dialysis shunt. On admission, he was diagnosed with bacterial meningoencephalitis and underwent a series of antibiotic chemotherapies. The treatment brought cell count in the cerebrospinal fluid to a subnormal level but his clinical status did not improve. The patient continued to have high level of cerebrospinal fluid protein (898 mg/dl). Cervical MRI demonstrated two abscesses deep in the neck as well as in the epidural region of the cervical spinal cord, from C2 to C5 vertebral levels. Based on these findings, spinal epidural abscess (SEA) was diagnosed. Intensive antibiotic chemotherapy especially targeted for MRSA could eradicate abscesses and improve clinical status. However, persistent high protein level in the cerebrospinal fluid could suggest SEA.

Cysts and tumors of the spleen are rare and are often discovered fortuitously. They are most often asymptomatic but may present with abdominal pain in the left upper quadrant. Splenic cysts are far more common than solid lesions; true cysts must be differentiated from pseudocysts of the pancreas and from cystic degeneration following splenic contusion or infarction. Cysts may be congenital (epidermoid cysts), infectious (abscess or hydatid cyst), or neoplastic (lymphangioma or angioma with tumor necrosis). Diagnosis can usually be established with the clinical context and imagery (ultrasound, CT, MRI). Surgery should be avoided for angiomas and pseudocysts. Spleen-conserving surgery is indicated for large symptomatic epidermoid cysts. Splenectomy is often required for hydatid cysts and tumors. Of the solid tumors, hemangiomas and lymphangiomas often have a characteristic fleshy appearance. For other solid tumors, whether benign or malignant, imaging may give some clues to the diagnosis, but diagnostic certitude often requires pathologic examination of the piece. Needle biopsy is contraindicated because of the risk of bleeding. Resection should be as limited as possible in order to avoid the risks of total splenectomy (overwhelming sepsis, thrombosis).

The administration of drotrecogin alfa (activated) improves outcome in adult patients with severe sepsis. Since the published pediatric experience with this drug is limited, the role of drotrecogin alfa (activated) in children, and especially in newborns is not well established. We describe a 3-day-old neonate with septic shock and multiorgan system failure, including circulatory, respiratory, renal failure, and disseminated intravascular coagulation, refractory to intensive fluid resuscitation and inotrope support. Within hours of drotrecogin alfa (activated) administration, the neonate experienced dramatic improvement in hemodynamic parameters. The infusion was discontinued after 48 hours, without clinical deterioration. Aside from transient thrombocytopenia, no significant side effects were observed. A brain MRI performed on day 18 after discontinuation of treatment was normal. The positive hemodynamic effect and outcome of treatment in this patient, indicates that drotrecogin alfa (activated) may play a similar role in the treatment of sepsis in neonates as already established in adults.

Critical illness polyneuropathy (CIP) is a sensorimotor polyneuropathy recognized in adult intensive care patients with sepsis and multiple organ dysfunction and only a few cases have been reported in children. Here we report a 13-year-old Japanese boy with CIP that developed during the course of encephalopathy. Two months after the onset of encephalopathy, he developed tetraplegia although consciousness had already recovered. Deep tendon reflex was absent. MRI of the brain and spinal cord was normal and no abnormality in the cerebrospinal fluid was detected. Motor and sensory nerve conduction velocities of the lower limbs and somatosensory evoked potential could not be detected. The motor activity subsequently showed gradual recovery, although standing and walking could not be achieved. Sural nerve biopsy performed 3 years after the onset showed severe reduction of the number of myelinated large-diameter fibers, thin myelin in almost all fibers and cluster formation of myelinated small-diameter fibers, indicating primary axonal degeneration with regeneration. We report here for the first time the neuropathological changes in peripheral nerves during the chronic stage of CIP in children.

Oesophageal cysts are rare congenital anomalies. Most commonly, they are located in the posterior mediastinum, approximately at the level of the distal third of the oesophagus. In most cases, they are diagnosed during childhood as an accidental finding of a symptomatic mediastinal lesion. A CT or MRI, oesophagoscopy and endosonography of the oesophagus are the essential diagnostic methods. In the adulthood, most of the cysts cause problems pushing against the surrounding organs and, therefore, surgical removal is recommended. In this report, a case of a potential complication is described: infection of the oesophageal cyst of the distal part of the oesophagus following a transoesophageal punction. The case resulted in sepsis, which was managed laparoscopically. Entering through the diaphragmatic hiatus,a cyst in the posterior mediastinum was revealed. The cyst was partially resected and its content evacuated. No complications followed. The laparoscopic method is feasible and safe even if the oesophageal cysts are infected. A complete resection of the cyst would be complicated due to a possibility of injuring the oesophagus. A significance of the peroperative oesophagoscopy to verify the oesophagus position in an unclear anatomic situation due to inflammatory infiltration, is highlighted. The above decreases the risk of the oesophageal wall lesion.

We report a 70-year-old woman with sarcoidosis and multiple cranial nerve palsy. The patient suffered from dysarthria, dysphagia and weakness of the upper and lower extremities and died of sepsis. No abnormalities were noted in brain MRI. At autopsy, numerous epithelioid granulomas with Langhans giant cells were present in the bilateral lungs, including the hilar lymph nodes. The brain had a normal external appearance. Histologically, there were brainstem parenchymal lesions consisting of many microgranulomas, lymphocytic infiltration, activated microglias and astrocytosis. Perivascular lympocytic cuffing was also seen. Neither granulomas nor lymphocytic infiltration were seen in the leptomeninges. The present case was considered to be a peculiar type of neurosarcoidosis, that is, "sarcoid brainstem encephalitis".

Purulent arthritis of the facet joint is a rare affection. It occurs most commonly by hematogenous spread of microorganisms and the initiating agent is in most cases Staphylococcus aureus. Diagnosis is made predominantly by means of MRI and hemocultures, or culture of pus aspirated from the abscess with a needle. Conservative therapy consists in a long-term administration of antibiotics. In case of insufficient response to the treatment or development of a neurological deficit, the patient is indicated for surgical revision, drainage and, if necessary, for decompression of nerve structures. In addition to sepsis, a severe complication of the purulent arthritis of the facet joint is propagation of the abscess epidurally, intradurally or foraminally with the risk of the onset of neurological deficit. In their case series the authors present four cases of purulent arthritis of the facet joint diagnosed and treated at the Department of Spinal Surgery of the University Hospital in Motol, Prague.
