ABSTRACT

Se presenta la experiencia quirúrgica en 160 pacientes con diagnóstico ecográfico de pólipo endometrial. Se evalúan las características epidemiológicas, clínicas y la correlación histológica. La edad promedio fue de 50 años, se analizaron las variables diferenciándolas en premenopáusicas o post menopáusicas, y presencia de síntomas. En todos los subgrupos la incidencia fue igualmente alta para los pólipos endometriales, seguida en frecuencia por los leiomiomas, hiperplasia endometrial y endometrio proliferativo, entre otros. Se encontraron 3 casos de adenocarcinoma endometrial, todos en el subgrupo de las pacientes postmenopáusicas sintomáticas. El procedimiento fue bien tolerado, y sin complicaciones. Destacamos a la histeroscopia como el estándar dorado por su alta sensibilidad y especificidad en el diagnóstico de pólipo endometrial.


The surgical experience in 160 patients with echographic diagnostic of endometrial polyps, are analyzed. Clinical and pathological characteristics are evaluated. The patient average age was 50 years old; variables were analyzed differentiating them in pre menopausal or post menopausal, according to the presence of symptoms. In all sub-groups the incidence was equally high for the endometrial polyps, followed in frequency by leiomyomas, endometrial hyperplasia and endometria proliferative among others. Three cases of endometrial adenocarcinoma were found, all in the sub-group of the symptomatic post menopausal patients. The procedure was well tolerated, without complications. We emphasized the hysteroscopy procedure as the gold standard by its high sensitivity and specificity in the endometrial polyp diagnosis.

ABSTRACT

Se analizaron 132 pacientes evaluando características epidemiológicas y clínicas, la correlación entre ecografía y anatomía patológica, la evolución y el uso laparoscópico en el tratamiento de masas anexiales. El diagnóstico se basó en la identificación ecográfica de una masa anexial. El rango de edad fue 16-66 años. El dolor abdominal y pélvico estuvo presente en 34 por ciento de los casos; en 45 por ciento se diagnosticó la masa anexial por examen ecográfico de rutina. En 53 por ciento de las pacientes se realizó quistectomía y en 16 por ciento ooforectomía completa. En 78 por ciento la masa correspondió a ovario y en 22 por ciento a trompa. Para las masas de origen ovárico la frecuencia mayor correspondió a tumores epiteliales (22 por ciento), seguido por quistes endometriósicos con 18 por ciento. Hubo 3 complicaciones vasculares y cambio a vía abierta en 5 casos. Solo hubo 1 tumor borderline y como hallazgo un cáncer de cuello uterino. El objetivo de este trabajo es presentar la experiencia quirúrgica en el manejo laparoscópico de los tumores anexiales.

ABSTRACT

El síndrome de hipoplasia ventricular izquierda (SHVI) es una malformación cardíaca de baja frecuencia pero es responsable de una gran cantidad de muertes por cardiopatía en el período neonatal e infantil. Si no es tratada quirúrgicamente, tiene una letalidad sobre el 90 por ciento en el primer año de vida. En Chile deberían nacer alrededor de 100 pacientes por año con esta cardiopatía. Presentamos la experiencia inicial del diagnóstico, manejo y evolución de un número importante de pacientes nacidos con SHVI y evaluados en el Centro de Referencia Perinatal Oriente (CERPO) en un período de 16 meses. Se reunió un grupo de 25 pacientes con diagnóstico pre y/o postnatal de SHVI. Se excluyeron tres mortinatos, un mortineonato y un caso con diagnóstico postnatal discordante. De los 20 pacientes con diagnóstico confirmado, en 12 se realizó cirugía. Los ocho restantes fallecieron. De los operados, el 58 por ciento falleció en el primer mes postoperatorio. Actualmente sobreviven dos. Si bien los resultados no son satisfactorios ha habido un importante progreso considerando la alta letalidad de esta cardiopatía y el poco tiempo de manejo sistemático multidisciplinario de esta malformación en nuestro medio. Esperamos alcanzar cifras de sobrevida más alentadoras dentro de los próximos años.

ABSTRACT

Revisaremos el lupus en su forma sistémica, que si bien puede presentarse a cualquier edad, es más frecuente en adultos.El LES en pediatría se ha descrito clásicamente de presentación más severa que en adultos, y se ha relacionado con la edad de diagnóstico. Su forma de presentación habitualmente es similar a los adultos, es decir, fiebre, compromiso articular y renal, compromiso del estado general y baja de peso de curso crónico, aunque en algunos casos se puede presentar en forma aguda como convulsiones, psicosis, falla reanl aguda, hemorragia pulmonar, serositis o alteraciones hematológicas.

ABSTRACT

BACKGROUND: Orthostatic tremor (OT) is clinically defined as a tremor of the lower limbs and trunk on walking. It bears a significant functional impairement. Although the term orthostatic tremor was first used by Heilman in 1984, Pazzaglia et al had previously described some cases in 1970. Despite the fact that the pathophysiology of this entity is not fully known, the presence of a central oscillator is generally accepted as being responsible. A high frecuency tremor, between 13 and 18 Hz, constitutes an almost patognomonic finding, and treatment with clonazepam usually improves the symptoms. PATIENT AND METHOD: We present a patient who described his symptoms as "cramps" in lower limbs and trunk on standing up, which were relieved on walking or resting. RESULT: This clinical presentation together with a neurophysiological recording of the tremor showing an activity of lower frequency (8 Hz) combined with the usual higher frequency (16 Hz) and above all the clear amelioration of symptoms when treated with gabapentin, i.e. resolution of the low frequency tremor without changes in the 16 Hz tremor, were the peculiar features of this case which merits discussion. CONCLUSIONS: The slow component of the orthostatic tremor is crucial in this case. The improvement with gabapentin is explained by the disappearance of this slow c

ABSTRACT

FUNDAMENTO: El temblor ortostático (TO) se define clínicamente como el temblor que aparece en las extremidades inferiores y el tronco durante la bipedestación y que habitualmente supone una importante incapacidad funcional. Aunque el término fue acuñado en 1984 por Heilman en la bibliografía inglesa como orthostatic tremor, previamente ya habían sido descritos los primeros casos por Pazzaglia et al en 1970. La fisiopatología del problema se sigue discutiendo, aunque se acepta la existencia de un oscilador central. La detección en los estudios neurofisiológicos de un temblor de alta frecuencia, entre 13 y 18 Hz, es casi patognomónica. Habitualmente el tratamiento con clonacepam mejora los síntomas. PACIENTE Y MÉTODO: Presentamos el caso de un paciente con calambres que le agarrotaban las piernas en relación con ortostatismo y cuyos síntomas se aliviaban con la marcha y el reposo. RESULTADOS: El registro neurofisiológico objetivó temblor con un componente armónico a menor frecuencia (8 Hz), coexistiendo con la frecuencia habitual a 16 Hz. El tratamiento con gabapentina mejoró los síntomas al desaparecer este componente lento. CONCLUSIONES: El componente lento del temblor es el factor fundamental que determina la clínica en este caso. La mejoría con gabapentina viene determinada por la desaparición de este componente lento (AU)

ABSTRACT

INTRODUCTION: Cisplatinum is a cytotoxic agent used in the treatment of different types of cancer. It often has side-effects, including a pure sensory syndrome with conservation of pain and temperature sense which is very disabling. CLINICAL CASES: We present the case of a woman with cancer of the ovary and a man with oat cell carcinoma, who were treated with cisplatinum. After the course of chemotherapy was finished, with accumulated dosages of 500 mg/m2, they both developed paraesthesia of all four extremities, reduced control of fine movements and unstable gait. On physical examination there was distal hypoaesthesia with conservation of temperature and pain sensation, areflexia and sensory ataxia. The patient with ovarian cancer also had continuous pseudo athetotic movements. On neurophysiological studies, there was absence of peripheral and central sensory potentials and of H reflexes, normal electromyogram, normal motor conduction and normal mixed silent period. DISCUSSION: The target organ in cisplatinum neurotoxicity has been identified, in experimental and human studies, as the dorsal root ganglion. Our patients had a syndrome which clinically and neurophysiologically suggested diffuse involvement of the dorsal ganglion (neuropathy) in which absence of sensory and H reflex potentials showed that the larger cells had been damaged. However, the normal mixed silent period suggested that the small myelinic cells were not altered, in accordance with the preservation of pain and temperature sensation. CONCLUSIONS: We discuss the differential diagnosis between neuropathy due to cisplatinum and to paraneoplasia. We consider that there may be a tendency for certain heavy metals to damage posterior root ganglia.

ABSTRACT

INTRODUCTION: The usefulness of neurophysiological studies of peripheral nerves depends basically on an understanding of the physiopathology, especially of the evolutionary aspects of the phenomena of reinnervation. CLINICAL CASE: We present the case of a girl with complete section and immediate anastomosis of the two cut ends of the median nerve, at the wrist. Sixty two days later she had unmistakable signs of reinnervation (response in the thenar eminence to an electrical stimulus of 300 uV in amplitude and 42 ms in latency, with denervation and reinnervation on the EMG of the abductor pollicis brevis muscle). DISCUSSION: The findings in our patient show a rather faster rate of nerve regeneration than is usually accepted in the literature. This may have been due to suitable selection of some of the parameters of the neurophysiological study, such as time of analysis and sensitivity, which when not satisfactory may lead to an impression of failure or delay in reinnervation.

ABSTRACT

OBJECTIVE: To determine the incidence, etiology and course of neonatal convulsions in the Albacete Health District between 1991 and 1993. DESIGN: A descriptive study of retrospective cohorts. SCOPE: 12,427 new born babies in the province of Albacete. The Hospital General de Albacete looks after a population of 376,071 inhabitants, attends 82% of the births in this area and its Neonatology Department is the only one in the province. METHOD: Incidence: we found 25 new born babies (RN) with neonatal convulsions: absolute incidence (IA) in live RN0/00.; IA in live full-term RN (RNI) 1.4(0/00); IA in preterm RN (RNPT) 13.4(0/00) and in immature RN (with a gestational age of < 29 weeks) 27.8(0/00). ETIOLOGY: hypoxic-ischaemic encephalopathy 32%, malformations or cerebral dysgenesis 24%, intracranial hemorrhage 16%, with less frequency: infections, metabolic and pharmacological changes 8%, epileptogenic diagnosis 4%. COURSE: 10 of the RN (40%) died, 8 (32%) had sequelae, although in 3 cases these were transient, and 7 had developed normally (28%). Other relevant aspects are described: neurological findings between crises, type of crisis, EEG and neuroimaging techniques. DISCUSSION: We attribute the poor prognosis of our series, as compared to other published series, to an increase in the incidence of convulsions associated with a worse prognosis (RN with antepartum fetal distress, cerebral malformations and metabolic encephalopathies), and a decrease in acute intercurrent conditions; hypoglucemia, hipocalcemia and hypothermia, which do not leave sequelae after treatment. Also when methods of clinical inclusion/EEG are used, evaluating only the epileptic phenomena, convulsive crises with minimal clinical signs are observed.

ABSTRACT

Rare complications of using the internal jugular vein for vascular access are related to puncture of neighboring organs or other structures. We report the atypical case of a 55-years-old woman with unilateral diaphragm paralysis attributed to accidental damage of the phrenic nerve during an attempt to canalize the internal jugular vein. Other more common causes were ruled out. The severe restrictive ventilatory changes produced had only minor clinical and gasometric repercussions, as previous function was normal and no acute or chronic respiratory disease was present. When ventilation is already compromised, however, this event could seriously worsen the patient's condition.
