VNS and pregnancy: A multicentric experience of four cases.

BACKGROUND: Vagus nerve stimulation system (VNS) has been employed worldwide as adjunctive therapy in drug-resistant epileptic patients. Only nine previous pregnancies with six-positive outcomes have been reported in women with epilepsy treated with VNS since 1998. AIMS OF THE STUDY: To communicate the experience of pregnancies in women treated with VNS in our country. METHODS: Clinical data of four female patients treated with VNS during pregnancy and delivery in five gestations is described. RESULTS: Four pregnancy outcomes were positive and one ended in spontaneous abortion, probably more related to the use antiepileptic drugs than VNS itself. Two births were vaginal and the other two with cesarean section. None of the complications during delivery were attributed to VNS. No teratogenicity was documented. CONCLUSIONS: Based on our experience VNS constitutes a safe therapy for the treatment of drug-resistant epilepsy in women of childbearing potential and during pregnancy and delivery. Larger series will be useful to confirm this finding.

[No fear of anything: epilepsy, psychiatric comorbidity and surgery. A clinical case report]. / Sin miedo a nada: epilepsia, comorbilidad psiquiátrica y cirugía. Descripción de un caso clínico.

INTRODUCTION: Psychiatric conditions are common in patients with drug-resistant temporal lobe epilepsy. It can be extremely disabling, as it hinders the patient's integration into society. Emotional symptoms may occur during crises or can be chronic and not directly related to seizures. Some of the most common disorders are depression, followed by anxiety disorders and obsessive symptoms such as phobias. CASE REPORT: In the clinical case reported here, the patient suffers from drug-resistant focal epilepsy and psychiatric comorbidity (anxiety-depressive syndrome and phobias). In the pre-surgical evaluation, the origin of the seizures was established as the right mesial temporal region, and so surgery was performed. In check-ups, an improvement of both conditions was observed after surgery to treat her epilepsy. CONCLUSION: The activation of the amygdala and its interaction with different brain structures seem to play an important role in emotional learning and aversive stimuli, thereby conditioning (depending on its pattern of activation) the individual's ability to control their fear. There seems to be excessive activation in individuals with phobias. Surgical resection by anteromedial temporal lobectomy in patients with temporal lobe epilepsy is an effective treatment to achieve control over refractory seizures, and may also help to ease emotional symptoms, thus adding an extra benefit. A pre-surgical evaluation with a multidisciplinary approach can be used to predict post-operative neuropsychological change.

TITLE: Sin miedo a nada: epilepsia, comorbilidad psiquiátrica y cirugía. Descripción de un caso clínico.Introducción. Es común que la patología psiquiátrica se manifieste en pacientes con epilepsia farmacorresistente del lóbulo temporal. Puede llegar a ser tremendamente incapacitante, puesto que obstaculiza la integración del paciente en la sociedad. Los síntomas emocionales pueden aparecer durante las crisis o presentarse crónicamente y no directamente relacionados con ellas. Entre los trastornos más frecuentes se encuentra la depresión, seguida por los trastornos de ansiedad y los síntomas obsesivos, como pueden ser las fobias. Caso clínico. En el caso clínico presentado, la paciente padece una epilepsia focal farmacorresistente y comorbilidad psiquiátrica (síndrome ansiosodepresivo y fobias). En la evaluación prequirúrgica se establece como origen de las crisis la región temporal mesial derecha, por lo que se realiza cirugía. En revisiones se constata una mejoría de ambas patologías tras la actuación quirúrgica sobre su epilepsia. Conclusión. La activación de la amígdala y su interacción con diferentes estructuras cerebrales parecen desempeñar un papel importante en el aprendizaje emocional y en estímulos aversivos, condicionando, en función de su patrón de activación, la habilidad del individuo para controlar el miedo. Parece existir un exceso de activación en los individuos que presentan fobias. La resección quirúrgica mediante lobectomía temporal anteromedial en pacientes con epilepsia del lóbulo temporal es un tratamiento eficaz para el control de las crisis refractarias, que, además, puede ayudar a remitir los síntomas emocionales, añadiendo un beneficio adicional. Una evaluación prequirúrgica previa con un enfoque multidisciplinar puede utilizarse para predecir el cambio neuropsicológico postoperatorio.

[Temporal pole encephalocele, a surgical treatable cause of drug-resistant epilepsy]. / Encefalocele del polo temporal: una causa tratable quirúrgicamente de epilepsia farmacorresistente.

INTRODUCTION: Encephaloceles are herniation of brain parenchyma through a bony skull defect that can cause drug-resistant epilepsy. In these cases, a surgical approach should be considered. CASE REPORT: 38-year-old man with drug-resistant epilepsy and 1.5 T magnetic resonance imaging performed with no relevant findings. After video-electroencephalogram, 3 T magnetic resonance imaging and F-18-fluoro-deoxy-glucose positron emission tomography, a right temporal encephalocele was confirmed. A right temporal polar resection was performed four years ago and the patient remains seizure-free. DISCUSSION: Anterior temporal encephaloceles are an underdiagnosed cause of epilepsy, and a 3 T magnetic resonance imaging reviewed by an epilepsy expert radiologists is key to diagnosis. CONCLUSION: In drug-resistant cases with presurgical evaluation compatible with the location, surgical treatment must be considered.

TITLE: Encefalocele del polo temporal: una causa tratable quirúrgicamente de epilepsia farmacorresistente.Introducción. Los encefaloceles son herniaciones del parénquima cerebral consecuencia de un defecto óseo. Si producen epilepsia farmacorresistente, hay que plantearse un abordaje quirúrgico. Caso clínico. Varón de 38 años con epilepsia farmacorresistente y estudio estándar de resonancia magnética de 1,5 T sin hallazgos. Tras realizar un videoelectroencefalograma, una resonancia magnética de 3 T y una tomografía por emisión de positrones con fluorodesoxiglucosa, se confirmó la presencia de un encefalocele del polo temporal derecho. Se efectuó una resección de ese polo temporal y cuatro años después el paciente continúa libre de crisis. Discusión. Los encefaloceles temporales anteriores constituyen una causa infradiagnosticada de epilepsia en cuyo estudio es clave la resonancia magnética de 3 T y la evaluación por un radiólogo experimentado en epilepsia. Conclusión. En casos farmacorresistentes y evaluación prequirúrgica de la epilepsia congruente con la localización, hay que considerar su tratamiento quirúrgico.

[Isolated hypoglossal nerve palsy secondary to an atlantoccipital joint synovial cyst. Case report and literature review]. / Parálisis aislada del nervio hipogloso secundaria a quiste articular atlanto-occipital. Presentación de un caso y revisión de la literatura.

Hypoglossal nerve palsy is commonly associated with the involvement of other cranial nerves. His injury is rarely isolated. We present a patient in which paralysis is due to the presence of a "juxtafacet cyst" of the atlanto-occipital joint. We review the anatomy of the hypoglossal nerve, different therapeutic options, the differential diagnosis and papers published to date.

[Chronic subdural hematoma associated with arachnoid cyst. Report of 12 cases]. / Hematoma subdural crónico asociado a quiste aracnoideo. Presentación de 12 casos.

INTRODUCTION: We designed this study to investigate the clinical, neurological, and radiological outcome of patients with chronic subdural hematoma related to an intracranial arachnoid cysts. PATIENTS AND METHODS: Medical records of 12 cases of patients with arachnoids cyst complicated with chronic subdural hematoma were retrospectively reviewed. RESULTS: Between January 1984 and April 2008, 12 patients (0.9%) of 1.253 cases of chronic subdural hematoma surgically treated in our hospital had associated arachnoid cyst. Arachnoid cysts were located in the middle fossa (10 cases) and convexity (2 cases). The most frequent symptom was headache (6 cases), followed by seizures (3 cases). Eleven patients underwent burr hole and drainage; the oldest patient was treated conservatively. CONCLUSIONS: Patients with AC, especially when these are located in temporal fossa, appear to harbour a life-long risk of contracting subdural hematoma. Hematoma evacuation is adequate at first operation and if arachnoid cyst is symptomatic or preoperative symptoms persist, additional arachnoid cyst surgery should be considered.

[Filum terminale ependymomas. Analysis of a serie of 20 consecutive cases]. / Ependimomas del filum terminal. Análisis de 20 casos consecutivos.

OBJECTIVE: to analyze the clinical, radiological and surgical outcome of a series of filum terminale ependymomas. Patients and methods. This retrospective study involved 20 patients with 21 ependymomas of the filum terminale encountered during a 21 year period (1988- 2008). All patients were diagnosed using MRI and surgically treated. RESULTS: the male: female ratio was 1:1.5, and the mean age at diagnosis was 44.8 years (range 15-64). First symptom included radicular pain (12 cases) and lumbar pain in the other 8 cases, with average symptom duration of 8.7 years (range 0-6-32). All patients underwent open biopsy, seventeen tumours received gross-total resection and 4 received subtotal resection. Histologically, 20 tumours were myxopapillary ependymomas (grade I) and 1 case a grade II ependymoma. The mean follow-up period was 8 years (range 1-18 years). CONCLUSIONS: filum terminale ependimomas are slow growing tumours of the cauda equina with a high incidence in young adults. The most common presentation is with low back pain long time evolution. Although ependymomas of the filum terminale are thought to be benign, local recurrence is not uncommon.

[Clinical efficacy of prostatic biopsy. Experience in our center from 1990 to 2002]. / Eficacia clínica de la biopsia prostática. Experiencia en nuestro centro 1990-2002.

INTRODUCTION: The prostate biopsy is the only valid tool to diagnose the existence of cancer of prostate. The indications of the biopsy, according with EAU, are the existence of high PSA, increased velocity PSA and a rectal suspicious tact. OBJECTIVES: validation of the utility of the prostate biopsy, to know the value of the PSA as a marker of prostate cancer in our way and to value the indication and efficiency of repeated biopsies. MATERIAL AND METHODS: we practice a manual review of the biopsies in our hospital, between the years 1990 and 2002. We study the level of PSA before the biopsy, number of prostatic cores and histologic information of the biopsy. A statistical descriptive and inferencial study has been performed by SPSS 12.0 package. RESULTS: The total number of biopsies registered was a 1202, with 36.96% of biopsy positive. The PSA before the biopsy (available in the biopsies realized between the year 1999 and 2002: 578 biopsies, 48.08% of the whole) was > 10 ng/ml in 55,88% of these patients, 4-10 ng/ml in 39.27% and 0-4 ng/ml in 4.84%. The average and PSA's median is of 19.09 (standard error: 1.87) and 10.6, respectively. The positividad of the biopsy increases with PSA's level: 48,61% with PSA > 10; 25.11% with PSA 4-10 and 21,4% in patients with PSA < 4. There was realized prostate rebiopsy (2 or more biopsies) in 132 patients (21.97% positive) 88,36% of the cancers was diagnosed in the first biopsy, and 6.62% in the second one (94,98% of the diagnoses of cancer of prostate carried out with the first 2 biopsies). CONCLUSIONS: The information obtained in the study by means of the descriptive analysis of our series meets in conformity the published in other studies and publications. There exists a need to increase the diagnostic profitability of the biopsy of prostate, for which we have introduced a protocol of biopsy under local anesthesia in order to be able to increase the number of obtained cylinders.

[Functional hemispherectomy: long-term follow-up in a series of five patients]. / Hemisferectomia funcional: seguimiento a largo plazo en una serie de cinco casos.

INTRODUCTION: Functional hemispherectomy consists in palliative epilepsy surgical procedure usually performed in patients with pharmaco-resistant epilepsy and hemispheric syndromes. It is based on the neural disconnection of the affected hemisphere with preservation of the vascular supply. AIM: To analyze long-term prognosis and safety of the hemispherectomies performed in our institution. PATIENTS AND METHODS: Retrospective analysis collecting the following variables: age, gender, age of epilepsy onset, type of seizures, etiology, age of epilepsy surgery, prognosis and potential surgical complications. All patients had a minimum of five years of follow up. RESULTS: Five patients (60% females) underwent hemispherotomy between 1999 and 2010. Age of epilepsy onset was 36 months and time of evolution until surgery was 7 years. The most frequent type of seizures were simple motor seizures with secondary generalization (n = 5). Three patients remained seizure free persistently after surgery and another patient had a more than 90% improvement. Time of follow up was 13 years. One patient suffered a bacterial meningitis without sequelae. Six years after surgery a patient suffered hydrocephalous requiring ventriculoperitoneal shunt. CONCLUSIONS: Functional hemispherectomy constitutes an effective method to treat patients with pharmaco-resistant epilepsy, extensive unihemispheric pathology and seizures limited to that hemisphere. Late complications may occur thus long-term follow-up is needed.

TITLE: Hemisferectomia funcional: seguimiento a largo plazo en una serie de cinco casos.Introduccion. La hemisferectomia funcional es una de las tecnicas quirurgicas con intencion paliativa que se pueden realizar en pacientes con epilepsia farmacorresistente y sindromes hemisfericos. Se basa en la desconexion neuronal del hemisferio afectado preservando el arbol vascular. Objetivo. Analizar el pronostico y la seguridad a largo plazo de las hemisferectomias realizadas en nuestro centro. Pacientes y metodos. Revision retrospectiva de los casos intervenidos, recogiendo las siguientes variables clinicas: edad, sexo, edad de inicio de la epilepsia, tipo de crisis, etiologia de la epilepsia, edad de intervencion, pronostico posquirurgico y posibles complicaciones. El seguimiento minimo fue de cinco años. Resultados. Cinco pacientes (60% mujeres) fueron intervenidos entre 1999 y 2010. La edad de inicio de la epilepsia fue de 36 meses, y el tiempo de evolucion hasta la cirugia, de 7 años. El tipo de crisis mas habitual fueron las crisis parciales simples motoras con generalizacion secundaria (n = 5). Tres pacientes permanecieron libres de crisis tras la cirugia, y otro paciente mejoro mas de un 90%. El tiempo medio de seguimiento fue de 13 años. Como complicaciones, una paciente sufrio una meningitis bacteriana sin secuelas posteriores. A los seis años de la cirugia, un paciente presento una hidrocefalia que requirio la implantacion de una valvula de derivacion ventriculoperitoneal. Conclusiones. La hemisferectomia funcional constituye un procedimiento quirurgico eficaz para el tratamiento de pacientes con epilepsia farmacorresistente, patologia hemisferica extensa y crisis limitadas a ese hemisferio. Hay complicaciones que pueden aparecer tardiamente, por lo que se aconseja un seguimiento a largo plazo de estos pacientes.

[Schistosomiasis: not an uncommon parasitosis in Europe]. / Esquistosomiasis: una parasitosis urinaria cada vez más frecuente.

UNLABELLED: Despite the fact that urinary parasitosis are very unusual diseases in our place, their frequency is growing up because of migration movements. CLINICAL CASE: A 28 years old subsaharian patient presented with haematuria and low urinary symptoms. The cystoscopic shows small white round granulate in bladder mucosa and anatomopathologic study informed about eggs an adult parasites on bladder biopsy. Despite of the infrequency of schistosomiasis in our country and because of migration movements we must include this disorder in monosimptomatic haematuria differential diagnosis.

[Kidney lipomatosis in a transplantation donor]. / Lipomatosis renal en donante cadáver.

OBJECTIVES: The aim of this clinical note is to report one case of incidental superficial renal mass during an organ explantation. METHODS: The renal donor was a 56-years-old male patient death for subaracnoidea haemorrhage without urological history. RESULTS: The anatomopathologic intraoperative study of the renal masses informed about the fatty nature of the tissue, and the renal implantation was performed. CONCLUSIONS: The find of a superficial renal mass during an organ explantatiation determine the necessity of a preoperative biopsy.

[Retrospective analysis of the effect of a vagus nerve stimulator implanted in paediatric patients with refractory epilepsy]. / Analisis retrospectivo sobre el efecto del estimulador vagal implantado en pacientes pediatricos con epilepsia refractaria.

INTRODUCTION: The vagus nerve stimulator is a therapeutic alternative in patients with epilepsy which is refractory to treatment with antiepileptic drugs that are not candidates for surgical resection. AIM: To analyse the effectiveness of vagus nerve stimulator in the paediatric patients of our centre. PATIENTS AND METHODS: Set of 13 patients implanted between 2008 y 2013. It was registered the frequency of crises prior to implantation, after a year and at the end of the monitoring period. As well, it was recorded the number of antiepileptic drugs used and in a qualitative way the behavioural improvement and the change in the intensity of the crises, besides the apparition of secondary effects and the removal or not of the device. RESULTS: After a year, two years and at the end of the monitoring period it has been a fall in the number of crises about of 61%, 66.7% y 69% respectively, finding one patient free of crises after two years. At the end of the monitoring period, the 23% of those who had reduced their crises had experimented a reduction over 90%. Independently the effect on the number of crises, 77% of the patients presented an improvement in the intensity and the length of the crises, the same average showed a behavioural improvement. The secondary effects appeared in a 30.7% of the patients, being of mild intensity. CONCLUSIONS: Despite the small size of our sample, our results shows that the vagus nerve stimulator has a relevant efficacy over the pediatric drug resistant population, as much in the frequency and intensity of the crises, as over the behaviour.

TITLE: Analisis retrospectivo sobre el efecto del estimulador vagal implantado en pacientes pediatricos con epilepsia refractaria.Introduccion.

Analizar la eficacia del estimulador vagal en los pacientes pediatricos de nuestro centro. Pacientes y metodos. Conjunto de 13 pacientes implantados entre los años 2008 y 2013. Se registro la frecuencia de crisis previa a la implantacion, al año, a los dos años y al final del seguimiento. Asimismo, se recogio el numero de farmacos antiepilepticos utilizados, de forma cualitativa la mejoria conductual y el cambio en la intensidad de las crisis, asi como la aparicion de efectos secundarios y la retirada o no del dispositivo. Resultados. Al año, a los dos años y al final del seguimiento se habia producido una reduccion en el numero de crisis del 61%, 66,7% y 69%, respectivamente, y uno de los pacientes se encontro libre de crisis a los dos años. Al final del seguimiento, un 23% de los que habian disminuido sus crisis habia experimentado una reduccion superior al 90%. De forma independiente al efecto sobre el numero de crisis, el 77% de los pacientes presento una mejoria en la intensidad y duracion de las crisis, y ese mismo porcentaje mostro una mejoria conductual. Los efectos secundarios aparecieron en un 30,7% de los pacientes y fueron de intensidad leve. Conclusiones. A pesar del pequeño tamaño de la muestra, nuestros resultados indican que el estimulador vagal tiene una eficacia relevante en la poblacion pediatrica farmacorresistente, tanto sobre la frecuencia e intensidad de las crisis como sobre la conducta.

[Intraventricular arachnoid cyst in the adult]. / Quiste aracnoideo intraventricular en el adulto.

INTRODUCTION: Intracranial arachnoid cysts are benign, congenial cystic lesions found in infancy. The commonest sites are the lateral fissure and the posterior fossa. Exceptionally they may be found in the ventricular system. CLINICAL CASE: We describe a 69 year old patient with a clinical history of headache and tingling of the face for 24 hours. Diagnosis of a lateral ventricle arachnoid cyst was made on computerized tomography and magnetic resonance. Treatment was surgical with excision of the wall of the cyst and the communication with the ventricle. CONCLUSION: We review 14 cases previously described (9 adults and 5 children), analyzing their clinical and radiological features, type of treatment given and the different theories proposed as to pathogenesis.

[Right varicocele as first manifestation of situs inversus]. / Varicocele derecho como primera manifestacion de un situs inversus.

Traditionally, right varicoceles have been considered a rare entity nearly always secondary to a neoplastic or retroperitoneal disease. There are other possible etiologies for right varicoceles such as the venous disease of the large veins and visceral malposition syndromes. This paper presents one case report of right varicocele as the only clinical sign of situs inversus. Revision of the literature and nomenclature of these syndromes.

[Inguinal bladder hernia. Report of 4 cases]. / Hernias vesicales inguinales. A propósito de cuatro casos.

Vesical hernias are, in general, a rare condition, except when they have an inguinal location. These are common, although their diagnosis is not so, and it is not infrequent that they are a chance finding of an inguinal herniorrhaphy procedure, during which relevant, but rare, complications have been described when the bladder has not been suitably identified. We present four cases of inguino-vesical hernia (three, massive hernia), and include a literature review.

[The clinical evaluation of kidney trauma: the practical indications for complementary examinations]. / Evaluación clínica del traumatismo renal: indicaciones para la práctica de exploraciones complementarias.

The aim of the present work is to try to know the clinical data that can provide directions on the attitude to take with patients who seek advise with a suspicion of renal traumatism, thus allowing to select those that may require complementary examination. This is a retrospective revision of 190 cases of renal trauma admitted in our hospital between 1971 and 1992. We rated 3 large syndrome groups based on the patient's major signs and symptoms. The first indication in 71 patients was haemorrhagic syndrome (shock or anaemia); 100 patients had microscopic or gross haematuria non-associated to anaemia; and 6 patients showed painful signs and symptoms. Existence of renal injury should be suspected in patients that came to the hospital with a background of trauma, microscopic or gross haematuria, shock with or without haematuria or intraabdominal lesions; the performance of complementary examinations is necessary in patients with evidence of gross haematuria, microscopic haematuria associated to shock or suspected associated extra-renal intra-abdominal lesions, or shock whether or not associated to haematuria.

[Local anesthesia in inguinoscrotal pathology]. / Anestesia local en patología inguinoescrotal.

Surgery, requiring the use of general orotracheal anaesthesia, has been the traditional treatment for many inguino-scrotal conditions. Over a number of years a gradual implementation of an alternative procedure consisting in the adoption of locoregional anaesthetic techniques has taken place, allowing to shorten hospital stays with the subsequent benefit for both the society at large, due of lower costs, and the patient through avoidance of general orotracheal anaesthetics and a faster discharge and return home. Based on these premises, 54 procedures were performed (16 inguinal varicocelectomies, 6 transinguineal orchiectomies, 21 hydrocelectomies, 3 spermatic cord cyst removals, 6 orchidopexy and 2 orchiectomies in patients diagnosed with testicular torsion). Our results demonstrate that this is an excellent technique which allows a ruled surgical procedure well tolerated by the patient and which allows to perform surgery without need of hospital stay.

[Malignant neoplasms of the penis]. / Neoplasias malignas del pene.

OBJECTIVE: To assess the behaviour and management of these uncommon neoplasias. MATERIAL AND METHODS: Between March 1975 and July 1999, a total of 95 malignant neoplasias of the penis were diagnosed and treated by our unit. Patients mean age was 62 years (28 to 87 years). A retrospective analysis of any associated lesions, biological behaviour of the various neoplasias, as well as therapies used is carried out. RESULTS: The squamous carcinoma of the penis (SCP) is the most frequent pathohistological entity entailing 78 cases (82%), followed by verrucous carcinoma (VC) 13 cases (13.5%), basal cells carcinoma 1 case, and melanoma, lymphoma and penile metastasis 1 case each. There is a significant presence of associated lesions with marked predominance of phimosis. The most frequent reason for the call is an injury of the penis (74 cases; 78%). Treatment was mainly partial penectomy (51 patients; 53.7%), followed by conservative treatment in 28 cases (30%). Inguinal lymphadenectomy was performed in 13 patients (14%), due to either a positive nodular biopsy or a persistent adenopathy following antibiotic therapy. CONCLUSIONS: Neoplasias showing superior biological behaviour are basal cell carcinoma of the penis, and verrucous carcinoma. Prognosis in SCP is based on pathological status and node involvement. Patients with pT1 tumours showed no metastatic adenopathies after follow-up regardless of cytological grading, and are therefore candidates to watchful waiting with regular monitoring. Melanoma of the penis is a highly aggressive tumour due to its high metastatic capacity with a poor prognosis.

[Can PSA density predict the response to alpha-blockers in benign prostatic hyperplasia?]. / Puede la densidad de PSA predecir la respuesta a los alfa-bloqueantes en la hiperplasia benigna de próstata?

INTRODUCTION AND OBJECTIVES: In BPH there is a growth of both glandular and stromal components. Most of adrenoceptors sites are in the fibromuscular stroma. So the higher is the stromal/epithelial ratio, the more effective will alpha-blockers be. There in an indirect way of stimating this ratio without performing a biopsy. Bearing in mind that PSA is produced by the prostatic epithelium, the lower PSA density (PSAd), the higher the stromal/epithelial ratio and the higher alpha-blocker activity. We pretend to study if PSAd is useful for predicting the response to alpha-blockers in BPH. MATERIAL AND METHODS: We studied 75 patients suffering from prostatism and diagnosed of bladder outlet obstruction secondary to BPH through IPSS symptom score, digital rectal examination, PSA, uroflowmetry, and transrectal ultrasound. All of them received Alfuzosin, 5 mg twice daily during 3 months, and then were evaluated again with IPSS and uroflowmetry. RESULTS: A statistically significant improvement was appreciated of the two studied parameters and in both groups of patient with regard to the pretreatment situation. A statistically significant better answer was also appreciated in the group of patient with smaller PSAd in comparison with the higher PSAd patients. CONCLUSIONS: Our results show that PDAd is usefu to estimate the stroma/epithelium ratio, and therefore the clinical response to alpha-blockers.

[Management of obstructive uropathy in pregnancy]. / Manejo de la uropatía obstructiva en el embarazo.

INTRODUCTION: Obstructive uropathy in pregnant women is a relatively common condition. It can be difficult to assess due to the frequency with which physiologic dilation of the upper urinary tract is seen in pregnant women. PATIENTS AND METHOD: Over the past 3 years 40 pregnant women with symptomatic obstructive uropathy were seen in our service. RESULTS: Most pregnant women responded to conservative treatment (pain killers and antibiotics). In the remaining group, instrumentation was necessary through the urinary route: double J ureteral catheterism (10 patients: 6 due to uterine compression and 4 to lithiasis), percutaneous nephrostomy (4 patients: 2 due to ureteral catheter obstruction impossible to replace, and two due to urinary sepsis), or ureterorenoscopy (1 patient with lithiasis). CONCLUSIONS: The single most common cause for obstructive uropathy in our experience is ureteral compression due to a gravid uterus. Choice therapy in most cases is conservative treatment. When in spite of conservative treatment signs and symptoms persist, urinary by-pass with antibiotic prophylaxis must be performed. Ureterorenoscpy as a diagnostic and therapeutical approach should be taken into consideration in pregnant women with ureteral lithiasis. Incidence of pre-term labour was not higher than usual.

[Brucellar orchiepididymitis]. / Orquiepididimitis brucelosa.

The brucellosis is an unusual entity whose incidence has diminished due to the improvement in preventive measures. We have carried out a retrospective study of all the patients admitted in our service between 1996 and 1998, with diagnosis of orchitis. Two of the 31 patients admitted for this reason presented a final diagnosis of brucellar orchiepididymitis. Both patients presented clinic of affectation from the general state accompanied by resistance to habitual antibiotic treatment. The patient's epidemic antecedents, accompanied by the suitable clinical evolution took to the suspicion of orchiepididymitis of brucellar etiology, with change in the antibiotic rule. The diagnosis of the process was obtained by means of serologic tests and blood cultures.
