[Follicular keratosis and multiple myeloma]. / Queratosis folicular y mieloma múltiple.

Follicular keratosis may be a rare paraneoplastic disease having unknown etiopathogeny that is sometimes associated to myeloma whose diagnosis and evolution follow a parallel course. We describe the case of a 57-year-old female patient diagnosed of multiple myeloma 8 years ago. She developed generalized follicular hyperkeratotic spicules coinciding with leukemization of the myeloma.

La queratosis folicular puede ser una rara enfermedad paraneoplásica de etiopatogenia desconocida, a veces asociada a mieloma, cuyo diagnóstico y evolución siguen un curso paralelo. Describimos el caso de una paciente de 57 años diagnosticada de mieloma múltiple 8 años antes, que desarrolló espículas hiperqueratósicas foliculares generalizadas coincidiendo con la leucemización del mieloma

Tratamiento de micosis fungoide con PUVA más bexaroteno / Treatment of mycosis fungoides with PUVA and bexarotene

Introducción. La utilización conjunta de bexaroteno y psoraleno y radiación ultravioleta A (PUVA) en la actualidad es un tratamiento en investigación. En el presente trabajo se presentan 6 pacientes tratados con esta combinación. Objetivos. Valorar eficacia y seguridad del tratamiento con PUVA más bexaroteno en pacientes con micosis fungoide. Pacientes, material y métodos. Seis pacientes diagnosticados de micosis fungoide en distintos estadios que han recibido PUVA, tres sesiones semanales (inicio 2,35 J/cm 2, con aumentos progresivos hasta llegar a un máximo de 23,5 J/cm 2) más bexaroteno (dosis inicial, 300 mg/m 2/día, disminuyendo a 200, 150 o 75 mg/m 2 si aparecía toxicidad). Todos los pacientes recibieron atorvastatina. Resultados. Al inicio de tratamiento, 2 pacientes se encontraban en estadio IIb, un paciente en Ib con afectación hemática B2, 2 pacientes en Ib y un paciente en estadio Ia. Cinco de los 6 pacientes respondieron al tratamiento (tres remisiones completas [RC], dos remisiones parciales [RP]). Un paciente no respondió. De los que obtuvieron RC, el tiempo hasta la respuesta fue de 10, 20 y 24 semanas, respectivamente. Todos los pacientes presentaron hipertrigliceridemia (máximo de 1.194 mg/dl). En cuatro de los pacientes fue necesario administrar suplementos de hormona tiroidea. Dos de ellos tuvieron alteraciones de la bioquímica hepática y dos más presentaron alteraciones analíticas del perfil muscular. Conclusión. La combinación de PUVA y bexaroteno es un tratamiento eficaz y seguro para la micosis fungoide. Habrá que esperar a los resultados de los ensayos clínicos en curso para ver si es mejor su uso combinado que el tratamiento con PUVA sola. El índice de respuesta fue del 86 % (3 RC y 2 RP de 6 pacientes)

Introduction. The combined use of bexarotene and PUVA is a treatment that is currently being investigated. In this paper, six patients treated with this combination are presented. Objectives. To assess the efficacy and safety of treatment with PUVA + bexarotene in patients with mycosis fungoides (MF). Patients, material and methods. Six patients diagnosed with MF in different stages, who received three sessions of PUVA treatment a week (initially 2.35 J/cm 2, with progressive increases to a maximum of 23.5 J/cm 2) + bexarotene (initial dose 300 mg/m 2/day, decreasing to 200, 150 or 75 mg/m 2 if signs of toxicity appeared). All received atorvastatin. Results. Stage at the start of treatment: two patients IIb, one patient Ib with B2 blood involvement, two patients Ib, one patient Ia. Five of the six patients responded to the treatment (three full remissions [FR], two partial remissions [PR]). One patient did not respond. In those in whom FR was achieved, the time required for the response was 10, 20 and 24 weeks. All presented with hypertriglyceridemia (maximum 1194 mg/ dL). It was necessary to administer thyroid hormone supplements to four of the patients. Two of them had alterations in the hepatic biochemistry values, and two others presented with alterations in the muscle profile analysis. Conclusion. The combination of PUVA and bexarotene is a safe and effective treatment for MF. It will be necessary to await the results of the clinical trials currently underway to see if their combined use is better than treatment with PUVA alone. The response rate (RR) was 86 % (three FR and two PR out of six patients)

Incidence of erectile impotence secondary to transurethral resection of benign prostatic hyperplasia, assessed by preoperative and postoperative Snap Gauge tests.

In an attempt to assess the impotence rate secondary to transurethral resection of the prostate more objectively than by merely interviewing patients, potency was evaluated with the Snap-Gauge test. The test was used preoperatively to recruit patients with intact potency. The 98 patients studied underwent transurethral resection of the prostate and were retested during postoperative night 4. Of the 98 patients 64 remained potent while 34 did not. These 34 men were retested 3 months later, and 26 were potent and 8 were impotent. Therefore, 8 of 98 patients (8.3%) became impotent as a consequence of transurethral resection of the prostate. The risk specific to subgroups in cases of small (less than 10 gm. resectable tissue) and larger adenomas is 11.1% and 7.7%, respectively, for men older than 65 years, and 7.1% and 0%, respectively, for men younger than 65 years. A selective indication taking into account patient age and prostatic size might further lower the already low impotence risk of transurethral resection of the prostate.

[Effects of Botulinum A Toxin on the periurethral striated sphincter of the neurogenic bladder. Preliminary study]. / Effets de la Toxine Botulinique A sur le sphincter strié périurétral des vessies neurogènes. Etude préliminaire.

The goal of this study was to try to determine the effects of the Botulinum A Toxin on the spasticity of the rhabdosphincter in 9 men with spinal cord injury and detrusor-sphincter dyssynergia. The cystometrography, before and after the endoscopic injection of 100 units of Botulinum A Toxin, consisted of recording the bladder, urethral and rectal pressures with microtip transducers the anatomical position of which was radiographically controlled. The subjective and objective results of that study allow us to conclude that the Botulinum A Toxin has a place in the treatment of spinal injuries with detrusor-sphincter dyssynergia. Due to his blocking effect on the release of acetylcholine in the motor nerve endings, the Botulinum A Toxin suppresses or decreases the spasticity of the rhabdosphincter and improves voiding. Although its relatively short living action (2-3 months) may require renewed injections, it has the advantage to hold off a surgical treatment such as a sphincterotomy and to give the patient another chance to reach a balanced bladder function secondary to the postinjection changes of reflexes which may have taken place between the bladder and the rhabdosphincter and vice versa.
