Lower urinary tract dysfunction and ultrasound assessment of bladder wall thickness in children with cerebral palsy.

Objectives: To evaluate lower urinary tract dysfunction (LUTD) based on questionnaire symptom scoring and ultrasound assessment of bladder wall thickness (BWT) in children with cerebral palsy (CP).

Methods: A total of 97 children with CP were enrolled in the study. The patients were either symptomatic or asymptomatic with respect to lower urinary tract symptoms.

Oxygen-bridged borate anions from tris(pentafluorophenyl)borane: synthesis, NMR characterization, and reactivity.

The previously known anion [(C6F5)3B(mu-OH)B(C6F5)3]- (2) has been prepared by a two-step procedure, involving deprotonation of (C6F5)3BOH2 to give [B(C6F5)3OH]- (1), followed by addition of B(C6F5)3. The solution structure and the dynamics of 2 have been investigated by 1H and 19F NMR spectroscopy. The reaction of [NHEt3]2 with NEt3 resulted in the formation of [NHEt3]+ [(C6F5)3BOH]-, [NHEt3]+ [(C6F5)3BH]-, and (C6F5)3B- (CH2CH=N+ Et2).

[Polymyositis as a paraneoplastic syndrome in a case of non-Hodgkin lymphoma].

The authors describe the case of a patient with NHL, who had undergone a series of clinical and laboratory investigations for the presence of pain, oedema and functional deficiency of the lower limbs associated with generalized weakness. From the data of the literature in cases of myositis, labelled as paraneoplastic disorders, no histological classification or phenotypic characterization have been provided, with exception of a case diagnosed as K1 positive lymphoma. A meta-analysis of case control studies and cohort of myositis and neoplasia do not show an increased incidence of cancer before a diagnosis of polymyositis (PM), although it seems to be an increased risk following diagnosis.

[Association between motoneuron disease and Waldenström macroglobulinemia].

The authors describe the case of a patient who was referred to their Unit because of polyneuropathy and was subsequently found to be affected by Waldenström's macroglobulinemia. A monoclonal paraproteinemia is frequently described in the serum of subjects with motor neuron disease. The association between motor neuron disease (MND) and lymphoproliferative disease (LPD) could be the result of a coincidence, but LPD seems to be disproportionally frequent in patients with MND, compared to the population in general.
