Hallazgos urodinámicos en pacientes con enfermedad de Charcot-Marie-Tooth con síntomas del tracto urinario inferior / Urodynamic findings in Charcot-Marie-Tooth patients with lower urinary tract symptoms

INTRODUCCIÓN: Nuestro objetivo fue describir los síntomas del tracto urinario inferior (STUI) y los hallazgos urodinámicos en pacientes con enfermedad de Charcot-Marie-Tooth (CMT) derivados a nuestro servicio de urología. MÉTODOS: Estudio retrospectivo de los pacientes con CMT diagnosticados en el servicio de neurología de nuestro centro y derivados al servicio de urología desde 2008 por sintomatología del tracto urinario inferior (STUI). Revisamos el tipo de CMT, la edad al diagnóstico, la presencia de comorbilidades que pudieran causar STUI, las características de los mismos, las exploraciones neurológicas y los hallazgos urodinámicos. RESULTADOS: Se remitieron 7 pacientes (3 varones y 4 mujeres) a nuestro servicio por STUI con una mediana de edad al inicio de los STUI de 55 (29-67) años y tiempo medio entre el diagnóstico de la neuropatía y el inicio de los STUI de 14 (1-37) años. Cinco pacientes refirieron clínica de vaciado, 3 incontinencia urinaria y 2 presentaban infecciones urinarias de repetición. Se realizaron 6 estudios urodinámicos, mostrando detrusor acontráctil neurógeno en 2 pacientes, detrusor hipocontráctil en un paciente, retraso en el tiempo de inicio de la micción en un paciente, detrusor hiperactivo en un paciente e incontinencia de esfuerzo en otro paciente. En un caso el estudio fue normal. CONCLUSIÓN: La mayoría de los pacientes con CMT y STUI refieren clínica de vaciado, pudiéndose relacionar con alteraciones urodinámicas, la mayoría en la fase de vaciado. Recomendamos la realización de estudio urodinámico en pacientes con CMT que presenten STUI y soliciten tratamiento o presenten complicaciones asociadas

INTRODUCTION: Our aim was to describe the lower urinary tract symptoms (LUTS) and urodynamic findings in Charcot-Marie-Tooth (CMT) disease patients referred to our Urology Department. METHODS: Retrospective study of those patients with CMT disease diagnosed at the Neurology Department of our Tertiary Hospital and referred to our Urology Department since 2008 due to LUTS. We reviewed their clinical charts regarding the age at CMT disease diagnosis, type of CMT disease and the presence of other comorbidities which could cause LUTS. We collected data on the characterization of LUTS, findings of neurological examination and urodynamic findings. RESULTS: Seven patients were referred to our department due to the presence of LUTS. They were 3 male and 4 female, with median age at the moment of LUTS onset of 55 (29-67) years and median time from the diagnosis of the neuropathy to the onset of LUTS was 14 (1-37) years. Voiding symptoms were referred by 5 patients and urinary incontinence by 3 PATIENTS: Two patients presented recurrent urinary tract infection. Six urodynamic tests were performed which showed a neurogenic acontractile detrusor in 2 patients, detrusor underactivity in one patient, a delayed opening time in one patient, a neurogenic detrusor overactivity in one patient and a urodynamic stress incontinence in one patient. In one patient the urodynamic test was normal. CONCLUSIONS: Most of CMT patients with LUTS complained from voiding symptoms. Several urodynamic findings could be observed mostly during the voiding phase. We recommend performing urodynamic tests in CMT patients presenting with LUTS seeking for treatment or in those with related complications

Hidatidosis paravesical. Presentación de un caso clínico / Bladder hidatidosis. Presentation of a clinical case

La hidatidosis primaria pélvica o paravesical es una forma excepcional de presentación de la enfermedad, mucho más común en pulmón, hígado y riñón. La clínica suele corresponder a trastornos irritativos miccionales. El diagnóstico de imagen es por ecografía, TAC y RNM. La serología es complementaria. El tratamiento médico es con albendazol pero la solución definitiva del quiste hidatídico paravesical es la cirugía. Se presenta un caso clínico de quiste hidatídico paravesical tratado con cirugía abierta, con una breve revisión de la literatura (AU)

Primary pelvic or paravesical hydatid disease is an exceptional presentation of the disease, more common in lung, liver and kidney. The symptoms are typically for irritative micturition disorders. The image diagnosis is by ultrasound, CT and MRI. The serology is complementary. Albendazole is pharmacological treatment but the final solution for the paravesical hydatid cyst is surgery. We present a case of paravesical hydatid cyst treated with open surgery, with a brief review of the literatura (AU)

Arachidonic acid metabolism in platelets of patients with essential thrombocythaemia.

Platelet aggregation tests and studies comprising [14C] arachidonic acid [14C]AA incorporation, release and metabolism were performed in resting and thrombinstimulated platelets of 11 patients with essential thrombocythaemia (ET) and 11 normal subjects. Nine patients had abnormal aggregation tests. Incorporation and distribution of [14C]AA in main platelet phospholipids (PLs) was similar in both groups. Activated platelets of patients with ET released more radioactivity from PLs that controls (13.7 +/- 5.4% versus 8.2 +/- 1.9%, p < 0.01). The formation of 12-L-hydroxy-5,8,10-heptadecatrienoic acid (HHT) was also increased (3.3 +/- 1.4% of total radioactivity versus 1.6 +/- 0.4% in controls (p < 0.0001). The same results were obtained for the generation of thromboxane B2 (p < 0.01). We did not detect differences in the formation of 12-L-hydroxy- 5,8,10,14-eicosatetraenoic acid (3.3 +/- 1.7% in patents versus 2.0 +/- 0.5% in controls). These results indicate that platelets of patients with ET have an increased activity of phospholipases and suggest a facilitated metabolism of arachidonate by the prostaglandinsynthetase pathway. Our results also demonstrate that impairment of aggregation tests in these patients was not due to a defective activity of the enzymes involved in the release and metabolism of AA by platelets.
