Non-Hodgkin's lymphoma of the uterus and CNS.

We report a case of a non-Hodgkin's lymphoma of the uterus and central nervous system in an 8-year-old female. The neurologic signs included blurred vision, neck stiffness, and walking difficulties but no abdominal problems. She deteriorated further, and repeated lumbar punctures revealed the presence of malignant cells in the cerebrospinal fluid. A repeated ultrasound scan of the abdomen demonstrated a markedly enlarged uterus. Biopsy revealed B-cell non-Hodgkin's lymphoma. Treatment according to the Berlin-Frankfurt-Münster protocol was initiated, but she developed hyperventilation syndrome and required mechanical ventilation. Her condition improved after 1 week but then deteriorated again, and despite additional chemotherapy she developed myelosuppression and septicemia with multiresistant Klebsiella pneumoniae and eventually died 13 months after her first admission to the hospital. No clinical or laboratory signs of relapse were evident at the time of death.

Association of Krabbe leukodystrophy and congenital fiber type disproportion.

Hypotonia and weakness developed in a 12-month-old boy whose psychomotor development had previously been normal. The muscle biopsy demonstrated a disparity in the mean diameters of type 1 and type 2 fibers and satisfied major histologic criteria for diagnosis of congenital fiber type disproportion (CFTD). However, deterioration of motor and mental function, which developed subsequently, strongly suggested progressive encephalopathy. Examination of leukocyte cerebral enzymes at 15 months of age revealed a complete lack of galactosylceramide-beta-galactosidase. Selective type 1 fiber atrophy with type 1 fiber predominance has been observed in various conditions, including Krabbe disease. We report an additional case of Krabbe leukodystrophy associated with CFTD. The finding on the molecular level will resolve the dilemma of whether CFTD is a congenital myopathy or whether these patterns of disproportion may result from a number of different processes that interfere with the maturation of the developing motor unit.

Shunt nephritis associated with Moraxella bovis.

Moraxella bovis was repeatedly isolated from cerebrospinal fluid in a girl with two episodes of shunt nephritis. Clinical remission of nephritis was achieved only after shunt replacement. A list of about 20 infectious agents reported to date in patients with shunt nephritis is given. M. bovis is yet another agent previously not reported in patients with shunt nephritis.

[Results of intensive therapy of meningococcal sepsis in children].

The authors report on the method, course and results of treatment of patients with meningococcal septicaemia. The two most common forms of meningococcal disease are meningococcal septicaemia (MS) and meningitis. Severe MS is a fulminant form of sepsis characterized by a rapidly spreading purpuric rash, haemodynamic instability and rapid progression to shock or death. The diganosis of MS was confirmed by isolation of NM in blood or cerebrospinal fluid, and/or positive solubile bacterial antigenes. However, in some children whose symptoms were consistent in MS (temperature and extensive purpura), no bacterial or soluble antigens were detected, particularly when they had been previours antibiotic treatment. Several scoring systems have been used to predict morbidity and mortility from MS. We selected the prognostic scor developed by Malley et al. Absolute neutrophil count less than 3 x 10(3)/mm3, platelet count less than 150 x 10(3)/mm3 and poor perfusion are indicators of poor prognosis. The presence of at least two of these indicators was associated with an 82% of risk of death. We reviewed the hospital records of 36 paediatric patients with acute meningococcal infection during a 5-year period. The age of our patients ranged from 2 months to 15 years (mean 4.4 yrs). Twenty seven (70%) of 36 children had MS and 11 (40.7%) had both MS and meningitis. Based on Malley scor, 13 (48.1%) patients had at least two predictors with > 82% of risk of lethal outcome. Four children (30.7%) died. Severe MS was diagnosed in 16 (59.2%) patients, who required mechanical ventilation (16; 59.2%), or continuous inotropic support and invasive measures of circulatory parametars (15; 55.5%). Shock treatment consisted of large volumes of crystalloid or colloid infusions thad ranged from 140 to 500 ml/kg/24 hrs (mean 215 ml/kg) Our results indicate that early controlled mechanical ventilations increase safety of large volume infusion with continuous invasive monitoring and inotropic stimulation, and may contribute to a greater survival of children with severe MS.

[Schimke immuno-osseous dysplasia].

Schimke immuno-osseous dysplasia (OMIM *242900) is a rare autosomal recessive disorder that affects primarily the bone, the immune system, the kidneys, the skin and the vascular system. The patients have intrauterine growth retardation, short stature with short neck and trunk, peculiar clinical phenotype: triangular face, broad nasal bridge, bulbous nasal tip, small palpebral fissures, long upper lip and low hairline. The characteristic features include spondyloepiphyseal dysplasia, hyperpigmented maculae, proteinuria with progressive renal failure, lymphopenia with recurrent infections and cerebral ischaemia. We describe a girl, 5 years old, with short-trunk type of dwarfism (height 75 cm, below 3rd centile), short neck, accentuated lumbal lordosis and protruding abdomen. The patient had peculiar face with a broad, depressed nasal bridge, bulbous nasal tip, and slightly elongated upper lip. The hair was thin and sparse. Numerous pigmented spots resembling lentigines were visible on the trunk and abdomen. Radiographs showed spondyloepiphyseal dysplasia. At the age of 2 years laboratory analyses showed normal growth hormone secretion, normal thyroid function tests, normal female karyotype and no mucopolisachariduria. Since the age of 4 years, several episodes of transitory right-sided hemiparesis with spontaneous recovery, were observed. Seizures occurred at 5 years of age, when the MRI brain imaging showed multiple areas of ischaemia. She also experienced transient nephrotic syndrome, lymphopenia and low IgG accompanied by septicaemia.

[West syndrome--new therapeutic approach].

West syndrome (WS) is an age dependent epileptic syndrome caused by various brain disorders. WS has been frequently classified in two groups, cryptogenic and symptomatic. As symptomatic WS consists of patients with numerous types of brain lesions, the prognosis and evolutional changes may be different among the types of brain lesions. WS is resistant to treatment to most conventional antiepileptic drugs, and only valproic acid, benzodiazepines, adrenocorticotropic hormone (ACTH), corticosteroids and vigabatrin have been found efficacious. Benzodiazepine, notably nitrazepam, and less clonazepam had been effective in bringing spasms under control but emerging tolerance and significant side effects (hypotonia and drowsiness) precluded its wider use. ACTH has been the treatment of choice for infantile spasms ever since Sorel and Dusaucy-Bouloye described its effectiveness in 1958. Despite the empirical approach steroids were capable of controlling the spasms and normalizing EEG in about 60% of cases. Corticotropin (ACTH) was used in doses from 5 to 180 I.U. daily, prednizolone 2-10 mg/kg daily, hydrocortisone 5-10 mg/kg daily and dexamethason 0.3-0.5 mg/kg. However, poor consensus was defined regarding the best steroid molecule to use, the dosage, and the duration of treatment. Also frequent and sometimes serious side effects have occurred during ACTH therapy, notably serious infections and hypertension that promoted continuous search for alternative and safer drugs tolerated outpatient treatment, good tolerance and minor side effects. Recently a specific visual field loss has been reported in treated adults that raised concern about safety of vigabatrin. New reports in children claim that vigabatrin treatment of children and adolescents has a lower risk for visual field defect than in adults, because of reported reversibility. Vigabatrin paediatric advisory group recommend the trial of vigabatrin for 12-14 days as first treatment for WS and in the case of good clinical response continuation of therapy for six months. Other new antiepileptic drugs (lamotrigine, topiramate, felbamate and zonisamide) have shown significant efficacy in the treatment of resistant WS to previous medication. The current task is to determine risk/benefit ratios of these two drugs (vigabatine, ACTH) and to delineate the group of patients with WS where their use would be optimal.
