ABSTRACT

INTRODUCCIÓN. El Síndrome de Wunderlich es un hallazgo infrecuente en la práctica urológica, se caracteriza por dolor lumboabdominal intenso, inestabilidad hemodinámica y masa palpable en flanco ipsilateral (Triada de Lenk). En la mayoría de casos, la etiología es de origen tumoral (Angiomiolipoma); así como discrasias sanguíneas y enfermedad renal quística adquirida, considerada como factor de riesgo para que ocurra hemorragia espontánea en pacientes con hemodiálisis a largo plazo. La tomografía computarizada es el examen de imagen estándar para el diagnóstico; el tratamiento va desde el manejo conservador hasta nefrectomía de emergencia. CASO CLÍNICO. Paciente masculino de 29 años con antecedentes de Hidrocefalia y Enfermedad Renal Crónica estadio IV, en tratamiento con Hemodiálisis. Acudió por dolor abdominal y descenso de valores de he-moglobina. RESULTADOS. En Urotomografía simple/contrastada se reportó hematoma retroperitoneal, por lo que se realizó una nefrectomía simple, se encontró un hematoma más trauma renal grado V. El paciente falleció en el posquirúrgico. DISCUSIÓN. Se han reportado algunos casos de Síndrome de Wunderlich relacionados a hemodiálisis que se acompañaron de dolor abdominal intenso, y se sospechó de esta patología. CONCLU-SIÓN. El diagnóstico temprano y tratamiento oportuno en el Síndrome de Wünderlich fue crucial para el manejo médico del paciente.


INTRODUCTION. Wunderlich Syndrome is an infrequent finding in urological practi-ce, it ́s characterized by intense lumbo-abdominal pain, hemodynamic instability and palpable mass in the ipsilateral flank (Lenk's Triad). In most cases, the etiology is of tumor origin (Angiomyolipoma); as well as blood dyscrasias and acquired cystic kidney disease, considered a risk factor for spontaneous bleeding in patients with long-term hemodialysis. Computed tomography is the standard imaging test for diag-nosis; Treatment ranges from conservative management to emergency nephrectomy. CLINICAL CASE. 29-year-old male patient with a history of Stage IV Hydrocephalus and Chronic Kidney Disease, undergoing treatment with hemodialysis. He came for abdominal pain and decreased hemoglobin values. RESULTS. A simple / contrasted urotomography revealed retroperitoneal hematoma, for which a simple nephrectomy was performed, a hematoma plus grade V renal trauma was found. The patient died postoperatively. DISCUSSION. Some cases of Wunderlich Syndrome related to he-modialysis that were accompanied by severe abdominal pain have been reported, and this pathology was suspected. CONCLUSION. Early diagnosis and timely treat-ment in Wünderlich Syndrome was crucial for the medical management of the patient.

ABSTRACT

Dementias are progressive and neurodegenerative neuropsychiatry disorders, with a high worldwide prevalence. These disorders affect memory and behavior, causing impairment in the performance of daily activities and general disability in the elders. Cognitive impairment in these patients is related to anatomical and structural alterations at cellular and sub-cellular levels in the Central Nervous System. In particular, amyloid plaques and neurofibrillar tangles have been defined as histopathological hallmarks of Alzheimer's disease. Likewise, oxidative stress and neuroinflammation are implicated in the etiology and progression of the disease. Neuronal precursors from human olfactory neuroepithelium have been recently characterized as an experimental model to identify neuropsychiatric disease biomarkers. Moreover, this model not only allows the study of neuropsychiatric physiopathology, but also the process of neurodevelopment at cellular, molecular and pharmacological levels. This review gathers the evidence to support the potential therapeutic use of melatonin for dementias, based on its antioxidant properties, its anti-inflammatory effect in the brain, and its ability to inhibit both tau hyper-phosphorylation and amyloid plaque formation. Furthermore, since melatonin stimulates neurogenesis, and promotes neuronal differentiation by inducing the early stages of neuritogenesis and dendrite formation, it has been suggested that melatonin could be useful to counteract the cognitive impairment in dementia patients.


Las demencias son enfermedades neuropsiquiátricas, progresivas, neurodegenerativas y con una alta prevalencia a nivel mundial. Ocupan uno de los primeros lugares como enfermedades que causan incapacidad en los adultos mayores. En estos pacientes el Sistema Nervioso Central presenta alteraciones anatómico-estructurales a nivel celular y subcelular que se asocian con deficiencias cognitivas. En particular, en la enfermedad de Alzheimer se han caracterizado marcadores histopatológicos como las placas amiloides y las marañas neurofibrilares. Se sabe que el estrés oxidativo y la neuroinflamación participan en la etiología y el desarrollo de la enfermedad. Recientemente se caracterizó a los precursores neuronales del neuroepitelio olfatorio humano como un modelo experimental adecuado para identificar biomarcadores de rasgo y para estudiar la fisiopatología de diversas enfermedades neuropsiquiátricas, así como el proceso del neurodesarrollo, a nivel celular, molecular y farmacológico. En este trabajo se presenta la evidencia que sustenta que la melatonina puede ser útil en el tratamiento de las demencias, por su capacidad antioxidante, por su efecto anti-inflamatorio, así como por el efecto inhibidor de la hiperfosforilación de la proteina tau y de la formación de placas amiloides. Además, al estimular la formación de nuevas neuronas, la neuritogénesis en sus etapas tempranas y la formación de dendritas, la melatonina podría contribuir a contrarrestar la pérdida de las funciones cognitivas que se observa en estos padecimientos.

ABSTRACT

Wild vectors and reservoir hosts of Trypanosoma cruzi were surveyed from February 1993 to June 1994 in Ticumßn (18 degrees 46'N, 99 degrees 07'W), Mexico (Deciduous Tropical Forest). Direct faeces examination showed that 87 of Triatoma pallidipennis hosted the parasite; T. cruzi forms were present in cultures inoculated with faeces of fifty 67 triatomine bugs and thirty CD-1 strain mice (10 d old) inoculated (peritoneum) with faeces of positive insects T. cruzi amastigotes were found in heart 67, kidneys 47, liver 80, lungs 50, oesophagus 60, skin 23, spleen 73 and stomach 60. T. cruzi was isolated by direct blood examination from seven 21 chiropterans and five 38 rodents and T. cruzi forms were present in cultures inoculated with blood of twenty-three 68 chiropterans and seven 54 rodents and T. cruzi amastigotes were seen in the kidneys of one 3 chiropterans and four 31 rodents and only in one Pteronotus parnellii mexicanus, organisms were seen in skin 2. There was no association between organs and T. cruzi infection (p > 0.05).
