RM nell'ambito delle malattie dolorose del retropiede e piu' in particolare nella sindrome dell'os trigonum, in considerazione della notevole difficolta' clinica per la corretta diagnosi. Lo studio e' stato condotto su sette pazienti che lamentavano dolore al retropiede da piu' di quattro mesi (maschi/femmine=1/6), con eta' compresa tra 16 e 22 anni (eta' media 18,6 anni); 3/7 praticavano attivita' agonistica sportiva, 4/7 danza classica. In 2/7 pazienti l'os trigonum presentava margini irregolari con sclerosi subcondrale e ampliamento della sincondrosi. In 3/7 pazienti e' stata documentata tenosinovite del tendine flessore lungo dell'alluce causata verosimilmente dalla sua compressione e spostamento all'interno della propria guaina, senza ne' alterazione dell'intensita' di segnale dell'os trigonum, ne' ampliamento della sincondrosi. In 1/7 pazienti sono stati rilevati ipertrofia dell'os trigonum, modico ampliamento della sincondrosi e segni importanti di edema midollare nell'os trigonum e nel processo posteriore dell'astragalo. In 1/7 pazienti, pur in presenza di os trigonum rilevato all'esame radiologico tradizionale, l'esame RM non ha documentato alcuno dei segni da riferire a sindrome dell'os trigonum: la diagnosi definitiva e' stata tendinite achillea. La RM e' l'unica metodica che fornisce importanti informazioni sul coinvolgimento dei tessuti molli, della superficie condro-ossea e sulle reazioni sinoviali riuscendo percio' a dimostrare chiaramente l'eventuale coesistente tenosinovite del tendine flessore lungo dell'alluce ed inoltre provvedendo a fornire informazioni dettagliate per il corretto approccio terapeutico. In conclusione, nell'ambito delle malattie dolorose del retropiede da cause ossee, laddove si sospetti clinicamente la sindrome dell'os trigonum, la non invasivita' della RM

[Italian] L'os trigonum tarsi e' un osso accessorio del piede localizzato in sede posterolaterale rispetto al tubercolo esterno dell'astragalo e di solito non da' alcuna sintomatologia. In particolari condizioni, che comportano sollecitazioni o microtraumi ripetuti nel tempo a livello del retropiede puo' essere responsabile di talalgia posteriore realizzando la cosidetta sindrome dell'os trigonum tarsi. Il dolore e' localizzato nella sede preachillea. La diagnosi tuttavia risulta particolarmente complessa i quanto numerose altre forme patologiche si manifestano con la medesima sintomatologia clinica. Con la radiologia tradizionale e' possibile dimostrare la presenza dell'os trigonum e le sue eventuali alterazioni morfo-strutturali. La RM (Risonanza Magnetica) di contro consente non solo di identificare le alterazioni strutturali dell'osso ma anche di riconoscere le lesioni associate dei tessuti molli. Sono stati studiati con RM nove pazienti affetti da sindrome dell'os trigonum tarsi. I pazienti sono stati esaminati nella posizione supina con il piede in posizione indifferente e successivamente bloccato nella flessione plantare. Lo studio e' stato condotto con magnete superconduttivo da 0,5 T impiegando una bobina dedicata per le estremita'. Sono state utilizzate sequenze spin-echo T1, gradient-echo T2* e fast inversion recovery secondo piani di scansione assiali e saggitali. In tutti i pazienti esaminati sono state valutate: sede e morfologia dell'os trigonum; caratteristiche dell'intensita' del segnale delle strutture ossee, cartilaginee e dei tessuti adiacenti; presenza di eventuali lesioni tendinee associate. Non sono state osservate anomalie di sede ne' di forma dell'os trigonum. L

Full Text Available La sindrome di Churg-Strauss è una malattia estremamente rara e ancora più raro è riscontrarla in una paziente in stato di gravidanza. Il trattamento iniziale della malattia consiste nella somministrazione di alte dosi di corticosteroidi. I pazienti più gravi o che rispondono poco o insoddisfacientemente ai corticosteroidi vengono solitamente trattati con farmaci citotossici. Le immunoglobuline somministrate per via endovenosa (IgEV stanno dimostrando di essere efficaci nel trattamento di questa patologia, tuttavia non esiste un consenso universale sulla loro effettiva utilità nelle vasculiti sistemiche. Noi presentiamo il caso di una donna con sindrome di Churg-Strauss resistente al trattamento con corticosteroidi e ciclofosfamide. Allorché si riscontrò che la paziente era al 3° mese di gravidanza fu iniziata una terapia con alte dosi di IgEV con ottimi risultati. Questo caso conferma l’utilità del trattamento con IgEV della sindrome di Churg-Strauss e ne dimostra l’efficacia anche in stato di gravidanza.

The Loxoscelism is caused by the bite of spider Loxosceles laeta gender, of worldwide distribution. The poisoning can cause lesions dermonecrotic and less frequently a systemic illness that can be fatal. The mechanism of venom action is multifactorial. The characteristic dermonecrotic lesion results from the direct effects of the venom on the celular and basal membrane components, as well as the extracelular matrix. The initial interaction between the poison and tissues, causes complement activation, migration of polymorphic neutrophils, liberation of proteolytic enzymes, cytoquines, aggregation platelet, and blood flow alterations that result in edema and ischemia, with development of necrosis. There is no a definitive treatment for loxoscelism. However, the value of specific antivenom, to decrease lesion size and limit systemic illness even when such administration is delayed. We present a case of cutaneous-visceral loxoscelismo with unfavorable evolution.

En su etiología se involucran factores como agentes químicos, radiación, inmunosupresión y síndromes y anomalías genéticas. Caso clínico: Varón de 64 años, que presenta lesión en piel de mejilla derecha de un año de evolución, localización en la que presentó hace veinte años un carcinoma basocelular tratado con radioterapia. Tras descartar existencia de metástasis, se realizó exéresis de la lesión con márgenes de seguridad y reconstrucción con colgajo de Mustardé. Se complementó el tratamiento con radioterapia. Discusión: El diagnóstico es anatomopatológico, siendo fundamental descartar afectación metastásica. Para mejorar la supervivencia y disminuir su elevada tasa de recidiva, deberían tratarse de forma multidisciplinar (cirugía, radioterapia y/o quimioterapia. Conclusión: A pesar de su baja frecuencia, los sarcomas deben estar presentes en el diagnóstico diferencial de toda lesión que aparezca en zonas radiadas previamente, especialmente en la piel facial.Introduction: Sarcomas are malignant tumors that are infrequent, being rare in the head and neck. Factors such as chemical agents, radiation, immunosuppression, and genetic syndromes and abnormalities are involved in their etiology. Case report: A 64-year-old man developed a skin lesion on the right cheek one year earlier at the site where he had presented a basal cell carcinoma 20 years earlier that was treated with radiation therapy. After ruling out the existence of metastasis, the lesion was treated by surgical resection with safety margins and reconstruction with the Mustardé flap. Treatment was supplemented with radiation therapy. Discussion: The diagnosis of sarcomas is histopathologic and it is essential to rule out metastasis. To improve survival and reduce the high rate of recurrence, a multidisciplinary approach to treatment should be used (surgery, radiation therapy and chemotherapy. Conclusion: Despite the low frequency of sarcomas, these tumors must be considered in the differential diagnosis of any lesion that appears on previously irradiated areas, especially on facial skin.

Unilateral hyperlucent lung is also known as Swyer-James Syndrome, Macleod Syndrome or lobular or unilateral emphysema. It is an uncommon disease characterized by lung or unilateral lobe hiperlucency associated to an air trapping upon expiration. As regards to etiology, this syndrome is considered to be an acquired disease that appears secondary to respiratory infections during the early years of life, probably bronchiolitis and/ or viral pneumonia. The clinical presentation varies among patients. Some of them are asymptomatic, others present a history of recurrent episodes of pulmonary infections from early years of life or present effort dyspnea. The diagnosis is usually made accidentally by a chest radiograph in a child with history of respiratory infections or in an adult during a routine chest x- ray in an asymptomatic person. It is important to differentiate this syndrome from other causes of unilateral pulmonary hiperlucency on conventional chest x-rays. Few cases of Swyer-James Syndrome in children have been reported, it is presented the clinical case of a patient who had a parainfluenza 3 bronchopneumonia when he was a month and eighteen days of age. The differential diagnosis of this syndrome should be done with other thoracic entities that diminish the radiological pulmonary unilateral density.

No es asi con la intoxicación aguda, puesto que sus signos y síntomas son reversibles. Presentamos un paciente con convulsiones parciales complejas, secundarias a un quiste temporal, que habia sido tratado irregularmente con DFH durante dos años con dosis variables que oscilaban en los 100 mg/dia. Dada la refractariedad de su cuadro convulsivo en una entrevista previa a su ingreso se le indico un aumento brusco de la dosis del fármaco que alcanzo a los 400 mg/dia. Ello ocasiono un sindrome pancerebeloso severo que motivo su internación. Posteriormente a la suspension de la DFH y la exeresis del quiste temporal mejoro su cuadro convulsivo, aunque quedo con ataxia de miembros inferiores y asinergia de tronco, cuadro con el que fue dado de alta. Un año despues, el paciente se encontraba libre de convulsiones, pero su sindrome cerebeloso no se habia modificado. El estudio por imágenes no evidencio atrofia cerebelosa.

It is well established that high-risk human papillomaviruses (HPVs) that infect mucosal epithelia are the causative agents of cervical cancer. In contrast, the association of cutaneo-tropic HPV types with the development of non-melanoma skin cancer (NMSC) is less well defined. In this study, we have analysed the in vitro transforming potential of various cutaneous HPV types. Using oncogene cooperation assays with activated ras, we have shown that diverse cutaneous types, including 12, 14, 15, 24, 36 and 49, have significant transforming potential. Interestingly, most of this activity appears to be encoded by the E6 gene product. In contrast, the common HPV-10 exhibits no significant transforming potential in these assays. This difference may be a reflection of different patterns of cellular localization, with transforming E6s being nuclear and non-transforming being cytoplasmic. These results provide molecular support for a role of these viruses in the development of certain human malignancies

effectiveness of the two quantitative parameters (intrinsic acromial angle and acromio-humeral distance) which are important causative factors in impingement syndrome. These parameters were found to be consistent and comparable with tue Bigliani classification of acromial morphology which, although providing useful qualitative data, does not fully respond to our quantitative needs. Our study suggests that impingement syndrome is negatively correlated to acromio-humeral distance and positively correlated to intrinsic acromial angle. These parameters, which are readily detected with MRI, may be used by the radiologist and orthopaedic surgeon to screen patients with nonspecific impingement syndrome. [Italian] Scopo. Lo scopo e stato quello di individuare un piano di scansione con alcune misurazioni associate che fornissero delle indicazioni quantitative sullo spazio subacromiale nei pazienti affetti di sindrome da impingement aspecifica. Materiale e metodi. Settantaquattro pazienti (47 maschi, 27 femmine, eta compresa tra 35 e 62 anni) che presentavano una sintomatologia da sospetta sindrome da impingement sono stati sottoposti al nostro studio. Le immagini sono state eseguite utilizzando sequenze SE TI pesate (TR 500 ms ,TE 12 ms ) e FSE T2 pesate (TR 3500, TE 25 ms) con bobina dedicata e scansioni acquisite lungo i piani sagittale obliquo e coronale.

Full Text Available PROFILUL AMINOACIZILOR LIBERI ÎN SERUL SANGUIN ŞI ÎN URINA COPIILOR CU SINDROM DOWNA fost investigat profilul aminoacizilor liberi în serul sanguin şi în urina copiilor cu sindrom Down, ce poate servi drept model al dizontogenezei. Aceasta din urmă este condiţionată de modificările genetice şi se caracterizează prin leziuni ale componentei cognitive a sănătăţii psihice. Rezultatele prezentului studiu sugerează implicarea directă a amino-acizilor liberi în dezvoltarea disfuncţiilor structurilor cerebrale şi diverselor sisteme ale organismului, ca urmare a unui dezechilibru al aminoacizilor cu conţinut de sulf, mediatori, esenţiali şi cetogeni. Acest dezechilibru duce în mod inevi-tabil la subdezvoltarea componentelor neurofiziologic, verbal, cognitiv, social-comportamental ale sănătăţii psihice.PROFILE FREE AMINO ACIDS OF SERUM AND URINE IN CHILDREN WITH DOWN SYNDROMEThere was investigated the amino acids profile of serum and urine in children with Down's syndrome, which can serve as a model dizontogenezis due to changes in gene and is characterized by lesions of the cognitive component of mental health. The results of this study suggest direct involvement of free amino acids in the development of dysfunction of brain structures and the various systems of the body as a result of an imbalance of sulfur, mediator, essential and ketogenic amino acids. This inevitably leads to underdevelopment of neurophysiologic, speech, cognitive, social and behavioral components of mental health.

Full Text Available Se analizan las condiciones fisiopatológicas del sindrome de hidrocéfalo de presión normal. De un grupo de 21 pacientes con sintomatologia clínica correspondiente a esta entidad, se seleccionan 10 que presentan un diagnóstico clínico, radiológico y cisternográfico indudable de la entidad en estudio. Se observó que, a pesar de esta selección solamente un 50% de ellos se vió beneficiado con la colocación de una válvula de baja presión. Surge entonces la hipotésis de que este cuadro es un sindrome multicausal; que por un proceso fisiopatogenico común produce un cuadro clínico, radiológico y cisternográfico similar y que serían beneficiados únicamente aquellos enfermos en los que se soluciona el problema mecánico.The physiopathological conditions of the normal pressure hydrocephalus syndrome are analysed. Within a group of 21 patients with clinical sinto- mathology pertaining this entity, only were 10 selected with a clinical, radiological and cisternografic indubitable diagnosis. It has been noticed that in spite of the stricked selection only a 50% of them have been beneficed by the application of a low pressure valve. Then, the hypothesis that the disease is a multicausal syndrome appears, which by an identical physiopathologic process produces or exhibits a similar clinical, radiological and cisternographic picture. Only those patients on whom the mechanical problem is solved would be beneficed by neurosurgery.

Epidermoid cysts are benign, uncommon lesions (1% of all intracranial tumors). Their localization is intradiploic in 25% of cases, and exceptionally subtentorial. We report here a rare case of giant intradiploic infratentorial epidermoid cyst. A 74-year old patient presented with recent diplopia and sindrome cerebellar. CT scan and MR imaging revealed a giant osteolytic extradural lesion of the posterior fossa (5.2 cm x 3.8 cm) with a small area of peripheral enhancement after contrast injection. Retrosigmoid suboccipital craniectomy allowed a satisfactory removal of the tumor, followed by an acrylic cranioplasty. The outcome was good. Neuropathological examination confirmed an epidermoid cyst. We review the literature and discuss our case.

The embryo and the human foetus are particularly sensitive to ionizing radiation and this sensitivity presents various qualitative and quantitative functional changes during intra-uterine development. Apart from radiation induced carcinogenesis, the most serious consequence of prenatal exposure in human beings is severe mental retardation. The principal data on radiation effects on human beings in the development of the central nervous system come form epidemiological studies carried out in individuals exposed in utero during the atomic explosion at Hiroshima and Nagasaki. These observations demonstrate the existence of a time of maximum radiosensitivity between the weeks 8 and 15 of the gestational period, a period in which the proliferation and neuronal migration takes place. Determination of the characteristics of dose-response relationship and the possible existence of a threshold dose of radiation effects on the development of the central nervous system is relevant to radiation protection against low dose radiation and the establishment of dose limits for occupational exposure and the public. Studies were conducted on the generation of nitrous-oxide and its relation with the production of active species of oxygen in brains of exposed rats in utero exposed to doses of up to 1 Gy during their maximum radiosensitivity. The possible role of the mechanism of radiation induced damage in the development of the central nervous system is discussed. 8 refs.

Esquistossomose pulmonar. II. Forma crônica reativada com hipertensão e Cor pulmonale

Jayme Neves

1980-12-01

Full Text Available Os Autores descrevem um caso grave de esquistossomose mansoni (forma hepática com hipertensão portal associada a forma pulmonar com hipertensão pulmonar e cor pulmonalej sobre o qual evoluiu uma sindrome toxi-infectuosa grave e de longa duração. Sucessivos exames radiológicos do tórax revelaram acometimento predominantemente arteriolar, ao lado de uma micronodulação pulmonar grosseira e difusa em ambos os hemitóraces e configuração de coração pulmonar. A histopatologia de material de biópsia pulmonar identificou basicamente uma arterite pulmonar característica, inflamação granulomatosa atípica provocada principalmente por vermes e raros ovos de S. mansoni envolvidos por escassa reação inflamatória. Para explicar a origem de constelação clínica toxi-infectuosa, foram afastadas as hipóteses de associação da esquistossomose a concausas infectuosas ou não, mas de curso febril, e a superposição de uma forma toxêmica sobre outra crônica pré-existente. Com base em dados clínicos, particularmente em subsídios da laparoscopia, e anatômicos, concluiu-se tratar o caso de uma forma crônica de esquistossomose reativada, provavelmente em virtude de alterações imunológicas inusitadas do hospedeiro. Ao que tudo parece indicar, o desvio de ovos e de vermes aos pulmões deveu-se à sindrome de hipertensão portal, cujos shunts entre a circulação portal e sistêmica determinaram a rota preferencial da migração.

Assinalam a dificuldade para o estabelecimento de uma classificação, em virtude da falta de conhecimento dos agentes etiológicos desencadeantes na maioria dos casos. Apresentam uma observação anátomo-clínica de mielo-patia neuro-óptica com artério e arteriolosclerose, em que a doença se iniciou pelo acometimento do nervo óptico direito, e, somente dois meses depois, surgiram os primeiros sinais de acometimento da medula espinal. No quarto mês de doença estabeleceu-se, de modo completo, o quadro medular, com uma sindrome motora tetraplégica pirâmido-extrapiramidal, outra motora primária nas extremidades distais dos membros superiores, por acometimento das pontas anteriores e, finalmente, uma sindrome sensitiva de tipo cordonai, abrangendo todas as formas de sensibilidade, a partir de C3. A enfermidade evoluiu em 12 meses, ocorrendo a morte em conseqüência de insuficiência respiratória de origem bulbar provável. O exame anátomo-patológico mostrou atrofia e esclerose total dos nervos ópticos, discretos infiltrados parvicelulares em torno de alguns vasos intracerebrais e piais e, na medula, um quadro histopatológico comparável ao que de regra se encontra na oftalmoneuromielite; apenas, no segmento cervical, onde as lesões eram muito extensas, havia foco de amolecimento mais pronunciado do que aqueles que se observam mais freqüentemente. 0 fato talvez decorra de esclerose arterial concomitante existente neste caso.

Full Text Available Nella periferia di Bologna sono nati recentemente nuovi spazi pubblici, molto diversi rispetto a quelli della città storica, che esprimono chiaramente  la mania della grandezza, la sindrome di Big Bologna. Ovunque si getta lo sguardo si notano nuove manifestazioni di una scala fuori proporzione che contribuisce alla segregazione sociale. Da quando sono arrivate le torri bianche della megastruttura di Kenzo Tange alla Fiera, la grande scala ha dato origine a spazi pubblici poco ameni per la vita urbana. Forse questi megaprogetti sono inevitabili segni dell’epoca della globalizzazione, ma ci si chiede se i committenti e i loro architetti sono stati consapevoli di quanto la progettazione di tali forme causa un deterrente alla socializzazione.

Chylothorax during childhood usually develops as a result of posto-perative complications following cardiothoracic surgery. It is rarely due to the malformations of the lymphatic system associated with dysmorphic syndrome. We report two cases of Noonan syndrome involving neonatal development of chylothorax. In children with the Noonan phenotype who develop pleural effusion during the neonatal period in the absence of obstetric trauma, it is advisable to rule out the presence of congenital lymphatic malformation and study the pleural effusion, initially introducing conservative treatment with dietary therapy. Chest radiography, ultrasound and computed tomography reveal the presence of the pleural effusion and parenchymal pattern compatible with chloroethoxy and lymphangiectasis. (Author) 15 refs.

Full Text Available SUMMARYAcute renal failure is a syndrome that usually runs with an increase in creatinine and urea plasma levels. However, there are clinical situations in which this syndrome may run with an increase in plasma creatinine keeping normal the urea one.In this report we present a case of acute renal failure with normal plasma urea level secondary to an acute pyelonephritis in a single kidney patient. The patient had an increased fractional excretion of urea which could explain the normal plasma urea levels found despite of his reduced glomerular filtration. This increased urea excretion state was interpreted as a consequence of the nephrogenic diabetes insipidus and alteration of the intra-renal urea reciclying process that the acute pyelonephritis induced. In conclusion: Acute pyelonephritis in a single kidney patient can appear as a pattern of acute renal failure with normal plasma urea levels. RESUMEN:La insuficiencia renal aguda es un sindrome que característicamente cursa con niveles plasmáticos elevados de urea y creatinina.

El paciente presentaba una elevada excreción fraccional de urea lo cual podía explicar su uremia normal pese a estar cursando una caída del filtrado gomerular. Dicha excreción de urea elevada fue interpretada como secundaria a una diabetes insipida nefrogénica y una alteración en el recirculado intra-renal de la urea ambos producto de la pielonefritis aguda. Concluimos que la pielonefritis aguda en un paciente mono-reno puede presentarse con un patrón de insuficiencia renal aguda con uremia normal.

Sin embargo, hay situaciones clínicas en las cuales este sindrome puede cursar con un incremento de la creatininemia sin presentar elevación de la uremia. En este reporte presentamos un caso clínico de una insuficiencia renal aguda con uremia normal secundaria a una pielonefritis aguda en un paciente con riñón único. El paciente presentaba una elevada excreción fraccional de urea lo cual podía explicar su uremia normal pese a estar cursando una caída del filtrado gomerular. Dicha excreción de urea elevada fue interpretada como secundaria a una diabetes insipida nefrogénica y una alteración en el recirculado intra-renal de la urea ambos producto de la pielonefritis aguda. Concluimos que la pielonefritis aguda en un paciente mono-reno puede presentarse con un patrón de insuficiencia renal aguda con uremia normal.SUMMARYAcute renal failure is a syndrome that usually runs with an increase in creatinine and urea plasma levels. However, there are clinical situations in which this syndrome may run with an increase in plasma creatinine keeping normal the urea one. In this report we present a case of acute renal failure with normal plasma urea level secondary to an acute pyelonephritis in a single kidney patient. The patient had an increased fractional excretion of urea which could explain the normal plasma urea levels found despite of his reduced glomerular filtration. This increased urea excretion state was interpreted as a consequence of the nephrogenic diabetes insipidus and alteration of the intra-renal urea reciclying process that the acute pyelonephritis induced. In conclusion: Acute pyelonephritis in a single kidney patient can appear as a pattern of acute renal failure with normal plasma urea levels.

Polycystic ovary syndrome (PCOS) is characterized by hyperandrogenism (H), oligo-anovulation (O) and / or polycystic ovaries (P). There is currently little information on perinatal complications. to investigate obstetric and neonatal characteristics of women with PCOS in our population. we studied 87 pregnant women with PCOS (categorized in four phenotypes according Rotterdam Consensus: A (H + O + P) n = 53; B (H + O) n = 9; C (H + P) n = 16 and D (O + P) n = 9) and 96 without PCOS (control). We analyzed clinical and biochemical features (age, anthropometry hirsutism, acanthosis nigricans, OGTT, insulin, lipid profile, androgen and gonadotropins) during preconception, (weight gain, blood pressure, OGTT) through gestation and occurrence of perinatal complications. we found no differences in age (29.4 ± 4 and 28.7 ± 5 years) and body mass index (28.2 ± 6 and 27.8 ± 6 kg / m2) in both groups; while patients with PCOS had higher waist circumference, blood pressure and acanthosis nigricans versus control. Despite similar weight gain, patients with PCOS had higher percentage of perinatal complications. In the A phenotype RR for perinatal adverse outcomes was 2.37 (95%CI: 1.67-3.36, p <0.001). The HOMA-IR index preconception and fasting glucose during pregnancy were the predictors for these complications (p=0.01). patients with PCOS have a higher risk for complications during pregnancy and newborns more frequently have low weight or macrosomy. A careful history can recognize patients with higher perinatal risk to develop complications.

Full Text Available Burnout is an English word that refers to something that crashed from exhaustion. It is a problem that affects service professionals, particularly those facing care activities with others, in which the provision of care or service often occurs in situations of emotional changes. The syndrome takes a multidimensional concept, whosemanifestation is characterized by emotional exhaustion, reduced personal accomplishment and depersonalization of the other. Taking into consideration that nurses, technicians and nursing assistants, are a great group with a predisposition to develop the syndrome because they are health professionals who spend more time in contact with the patient and their family members within the work environment emotional situations of constant change, we performed abibliographic review in order to gather information on key risk factors that favor the onset of the Burnout syndrome and its consequences for the individual, organization and society. This work will serve as a subsidy for reflection and discussion, both the professionals involved, as future managers and professionals.

Full Text Available In the last decades, we have seen a rapid growth in the culture of prevention, safety and care for people involved in dramatic events. These calamites, both natural and human made, can have a profound effect on the mental stability of individuals and communities. These effects can have consequences on people, which may go on for days, months and even years during the recovery, rebuilding and re-establishment of an ordinary situation. Each event due to these circumstances is an emergency from a technical-practical and also human point of view. And that is because people are forced to fight in order to survive physically and emotionally in a state of dangerousness and dramatic force. During an emergency it is necessary to help people recognize normality in their own reactions, which are consequences of a situation out of ordinary. A greater focus on the emotional and cognitive component of the person involved is needed. Actually, this component proves to be very important both for the successful management of the situation - being involved in the prevention and preparation phases - and for its contribution to a mitigation of the effects of a specific event. It is widely known that during an emergency, interventions by psychologists trained to face various contexts (e.g., incidents, natural disasters and so on and able to cooperate with other professionals are needed. The aim is to promote in the people involved, both rescuers and victims, the capacity to cope with the situation, in the short term and in the long term.

Once the diagnosis of Cushing's syndrome (CS) has been established, the main step is to differentiate between ACTH dependent and independent disease. In adults, 80% of CS is due to ACTH-dependent causes and 20% due to adrenal causes. ACTH-secreting neoplasms cause ACTH-dependent CS. These are usually anterior pituitary microadenomas, which result in the classic Cushing's disease. Non-pituitary ectopic sources of ACTH, such as a small-cell lung carcinoma or carcinoid tumours, are the source of the remainder of ACTH-dependent disease. In the majority of patients presenting with clinical and biochemical evidence of CS, modern non-invasive imaging can accurately and efficiently provide the cause and the nature of the underlying pathology. Imaging is essential for determining the source of ACTH in ectopic ACTH production, locating the pituitary tumours and distinguishing adrenal adenomas, carcinomas and hyperplasias. In our chapter we review the adrenal appearances in ACTH-dependent and ACTH-independent CS. We also include a discussion on the use of MRI and CT for the detection and management of pituitary ACTH secreting adenomas. CT of the chest, abdomen and pelvis with intravenous injection of contrast medium is the most sensitive imaging modality for the identification of the ectopic ACTH source and detecting adrenal pathology. MRI is used for characterising adrenal adenomas, problem solving in difficult cases and for detecting ACTH-secreting pituitary adenomas. (author)

A comparison of the preoperative findings was performed in patients with the diagnosis of carpal tunnel syndrome, with functional outcomes and postoperative residual pain, using the scale Patient Rate Wrist Evaluation (PRWE). All patients have had clinical history, physical examination and electromyography studies. They were operated by minimally invasive open surgery. The information was collected in an Excel table and patients have located via telephone. 100% of the evaluated patients have engaged in activities that involve trauma or repetitive wrist movements. The physical sign with predicative positive value for suspect of carpal tunnel syndrome has been the Phalen, present in over 70% of cases. The amount of physical signs present preoperatively and postoperative results were found without correlation. The mixed lesion, both sensory and motor has been the most found in electrodiagnostic studies. Patients whose studies have been negative, postoperative results have showed less favorable.

Se considera a la encefalopatia hipertensiva seudotumoral como una complicación relativamente frecuente de la hipertensión maligna arterial primitiva aunque también puede ser provocada a consecuencia de otros procesos causantes de hipertensión arterial (endocrinos, renales, vasculares, etc. Se describen algunas observaciones de encefalopatia hipertensiva en que se planteó el diagnostico diferencial con un tumor cerebral. Los signos clinicos focales (sindrome de Foster-Kennedy, sintomas cerebelosos, etc. aumentaron en algunos casos las dificultades diagnósticas. Se señala la importancia de los exámenes complementarios especialmente de la arteriografia cerebral y neumoencefalografia que han permitido casi siempre evitar errores diagnósticos.

Full Text Available Hyperlexia is an extraordinary skill for spontaneous early reading in the background of an autistic child with serious linguistic disorders. Generally it is a mechanical skill in the transcodification of graphemes to phonemes but there is lack of comprehension. We present the clinical characterization of a case of hyperlexia in an autistic boyas a transcortical developmental aphasia that originated perhaps in a neurodevelopment disconnection syndrome. La hiperlexia es una habilidad excepcional para el aprendizaje precoz y espontáneo de la lectura, en el contexto de un severo retraso en el desarrollo del lenguaje y un sindrome autista. En general es una habilidad mecánica en la transcodificación grafemo-fonemática pero carente, en gran parte, de capacidad comprensiva. Se presenta la caracterización clínica de un cuadro de hiperlexia como disfasia transcortical del desarrollo en un niño autista, originado posiblemente en un síndrome de desconexión durante el neurodesarrollo.

Full Text Available The idiopathic hypereosinophilic sindrome (HES is a disease characterized by persistent blood eosinophilia (> 1500 eosinophils/mm3 > 6 months-in absence of other ethiologies for eosinophilia (parasitic, allergic, immunological or malignant diseases-associated with multiple organ involvement (heart, lung, central nervous system, skin, bone marrow, gastrointestinal tract. Reports on rheumatologic manifestations in patients with HES are very rare. In the case we report a typical rheumatoid arthritis developed in a 58-year-old woman with HES treated with glucocorticoids. Because of the marked glucocorticoids side effects shown by the patient(cushingoid habitus, hyperglycemia, we stopped this treatment and replaced it at first by methotrexate and later by cyclosporin, both of them associated with sulfasalazine. These drugs revealed very efficacious both on articular pathology and on the clinical and laboratory manifestations of HES. These data suggest that common pathogenetic mechanisms are likely acting in rheumatoid arthritis and idiopathic hypereosinophilic syndrome.

Full Text Available El estres es un hecho complejo en la vida de toda persona con efectos distintos en cada quien, que no puede ser evitada ya que en todos lo momentos de la vida se esta en riesgo de presentarlo ante cualquier situacion, o una actividad laboral o familiar, que puede llegar a generar cualquier cambio que represente estres. Los sucesos negativos, dario, enfermedad o muerte de un ser querido, son hechos estresantes, asi como los sucesos positivos; ascender en el trabajo trae consigo el estres del nuevo status, de nuevas responsabilidades. Dentro de los trastornos clinicos vinculados al estres hay alteraciones como: trastornos del sumo, ulceras, dolores de cabeza, aceleracion del ritmo cardiaco y otros trastornos como los cardiovasculares: palpitaciones, hipertension arterial, trastornos digestivos, dolores, ardores, vomitos, nauseas, diarrea o estreriimiento y trastornos cutaneos: donde se presenta transpiracion de manos y pies y problemas alergicos. En el estres se pueden llegar a presentar dos tipos de estres: el positivo y el negativo. Los cuales presentan unas caracteristicas muy particulares, como en el estres negativo: una persona se encuentra ante un nitmero creciente de demandas que le plantean dificultad o constituyen una amenaza, se debe mirar el modo de afrontarlas. En el Estres positivo se presenta cuando la percepcion de capacidad de demanda es mucho mas amplia que las verdaderas demandas. Un aspecto fundamental ante la presencia de estres es la practica necesaria de un deporte o la realizacion de actividades recreativas.

Full Text Available SUMMARY:Sleep disordered breathing (SDB is a common condition in children. Sleep Apnea/Hypopnea syndrome (SAHS in children is a frequent sleep disorder, with a prevalence estimated to be 1 - 3% of all children. The most frequent cause of SAHS in children is the adenotonsillar hypertrophy. SAHS in children can result in severe complications if left untreated such as impaired physical growth, delayed development, poor school performance and in severe cases, hypertension and cor pulmonale, nevertheless, yet it is an under recognized condition. The gold standard diagnostic technique is the nocturnal polysomnography (PSG, guidelines for performing laboratory-based polysomnography in children have been established, the sleep laboratory should be a nonthreatening environment and personnel with pediatric training should record, score and interpret the study. The diagnostic criteria for SAHS in adults is not useful for diagnosis of SAHS in children. Adenotonsillectomy is the most common treatment for children with SAHS.RESUMEN:Los trastornos respiratorios del sueño en los niños, en particular el Síndrome de Apneas/Hipopneas durante el sueño (SAHS, es una patología frecuente, que afecta entre el 1 - 3% de la población infantil, siendo su causa más frecuente la hipertrofia adenoamigdalar. Es una enfermedad infradiagnosticada y que conlleva importantes complicaciones como son alteraciones del crecimiento, alteraciones cognitivas e incluso en casos severos Cor Pulmonale. La polisomnografía nocturna (PSG, es la técnica diagnóstica de elección para el diagnóstico del SAHS en los niños, pero en la población infantil es necesario tener en cuenta una serie de consideraciones, como son la edad de la población que se estudia, entorno adecuado y la necesidad de técnicos entrenados en el cuidado de los niños. Los criterios diagnósticos del SAHS para adultos no son útiles en los niños. El tratamiento de elección en los niños con SAHS es la adenoamigdalectomia.

Full Text Available Background: Metabolic syndrome (MetS is a disease of disorder of lipid and nonlipid metabolism. The West of Scotland Coronary Prevention Study found that men with MetS had probability 3.7 dysfunctions of erection (ED by using International Index of Erectile Function (IIEF. Patient with heart disease had the risk 2 times to get ED, hypertension was 1.5-2 times, DM was 3-4 times, depression was 2-3.5 times, testosterone deficiency syndrome (TDS was 1.5-2 times, and high cholesterol was 4 times. The nutrient deficiency of zinc (Zn and magnesium (Mg was suspected being the main component which had a role in resisting a sexuality growth and maturation process. Objective: Knowing the correlation of Zn and Mg feeding with erection dysfunction in MetS person. Method: This study was observational analytic study, with case-control design in the patient aged 30-60 years old. The respondent in this study was people with MetS according to WHO criterion. There was 82 patient divided into two groups, consist of 41 cases of MetS and ED, 41 cases with the normal patient. The data collected by interview, laboratory assessment and anthropometric measurement. The data analysis using univariate, bivariate and multivariate analysis using multiple logistic regression. Results: There was significant correlation between Zn feeding and ED (OR=7.15; 95% Cl=1.47-34.71; p=0.007 and there was significant correlation between Mg feeding with ED (OR=3.34; 95% Cl=1.07-10.4; p=0.033. The end result of the multivariate analysis showed the risk variable to the ED event, that was Zn feeding with OR=15.41. If the intake of Zn accompanied with risk factors associated as a cause of ED, multivariate analysis showed HbA1c’s degree with OR=12.57; triglyceride (OR=10.47; blood pressure (OR=5.82; and abdominal obesity (OR=6.94. The result shows that these risk factors can aggravate or anticipate the onset of dysfunction erection beside low Zn intake. Conclusion: There was statistically significant correlation between Zn and Mg feeding with erection dysfunction in MetS patient.

Nowadays, prenatal exposure is a very important topic in radiopathology.Unfortunately, pregnant women have been sometimes exposed or have to expose to ionising radiation, for example, during a medical treatment.There are lots of studies made by the International Commission of Radiation Protection (ICRP) about the effects of ionising radiation and the consequences that are suffered by the exposed foetus.Hence, it has been argued that developing mammalian brain is substantially more susceptible to teratogenic insult than most other embryonic and foetal structures.Presumably, this reflects its architectural complexity, its long developmental period, the vulnerability of the undifferentiated neural cell and the inability of the brain to replace lost neurones.Furthermore, there is abundant information on the biological effects caused by prenatal exposure of mammals to ionising radiation.Only two conspicuous effects on brain growth and development have emerged thus far in the study of atomic bomb survivors exposed prenatally in Hiroshima and Nagasaki.These are some cases of severe mental retardation and some of small head size without apparent metal retardation. Additionally, groups within the survivors have shown significantly reduced IQ scores.This increase would be dose-related and, if the shift of IQ had no clear dose threshold, might, in turn, show no threshold.Besides, it has been studied that ionising radiation implies molecular ionisation and excitation in the biological systems.When radiation has a high linear transfer energy (LET) damage may be produce trough energy absorbed directly by the target molecule (direct mechanism).However, when radiation has a low LET (like {gamma} and X radiation), and without forgetting that biological systems are basically aqueous, damage may be produce trough generation of species highly reactive (like free radicals and reactive oxygen species - ROS) by molecules of water which has adsorbed energy radiation (indirect mechanism).In this context, nitric oxide (NO) is a diffusible multifunctional extracellular messenger that has been implicated in numerous physiological functions in mammals ranging contraction of muscles, dilation of blood vessels, neurotransmission, potentiation of synaptic transmission, immune defence and, also, it can be involved in reactions that produce cell damage.As a consequence of this, an intracellular increase in the number of frees radicals and in the ROS determines a very important cellular injury trough oxidative stress.In this study, pregnant Wistar rats were exposed after 17 days of gestation (d.g.) to 1 gray (Gy) gamma irradiation from a cobalt (Co{sup 6}0) source.Even though it is establish that {gamma} radiation-dependent damage is mainly due to free radical generation, neither the ascorbyl radical/ascorbic acid ratio nor lipid radicals content in developing rat brain was affected by prenatal irradiation.In addition, a distinctive electronic paramagnetic resonance (EPR) signal for the adduct NO-Fe-MGD (g=2.03 and a{sup N} = 12.5 G) was detected in foetal brain homogenates.NO dependent EPR signal increased up to 2 h post-irradiation.NO concentration in unirradiated brains was 37{+-} 4 pmol/g and 45{+-} 2, 77 {+-} 5 and 216{+-} 6 after 30, 60 and 120 min post-irradiation, respectively.Also, total nitric oxide synthase (NOS) activity was increased by 100% and 51% after 30 and 60 min post-irradiation, respectively, and returned to control values after 120 min.Therefore, it was studied whether the quantity of NOS mRNA varies at 1, 2, 6 and 24 Hs post irradiation.As a consequence, a reverse transcription (RT) and polymerase chain reaction (PCR) amplification was performed.From the analysis of electrophoretic gel from the obtained cDNA, the values of relative areas for bands due to nNOS cDNA, were 3.23, 3.73 after 1 and 2 hours post-irradiation, respectively, and were not significantly different from control values.Similarly, relative areas for bands due to iNOS cDNA, were not significantly different from controls neither.Although these results suggest it might be possible that NOS mRNAs do not vary after irradiation, more experiments ought to be made in order to find conclusive data. All in all, in spite of NO may increase the number of frees radicals and ROS determining a very important cellular injury trough oxidative stress in several systems, NO may play a completely different role in developing neurones.It could be mainly by mediating neuroprotective effects trough avoiding lipid peroxidation in vivo, due to that it cannot be detected any alteration neither in ascorbyl radical/ascorbic acid ratio nor in lipid radicals content in developing rat brain.Moreover, it has been shown that apoptosis rate goes down in cultures which have been exposed to ionising radiation in the presence of NO donors.

A 14 year old girl having 10-days lumbar pain, polaquiuria and moderate pain to palpation is reported. Blood and urine analysis were normal. Abdominal ultrasound scan showed cavity free and solid, rounded, heterogeneous, intrapelvic mass compressing bladder and uterus. Magnetic resonance image was performed showing right gonad compromise with extensive liver and sacro-lumbar spine invasion. Tumoral markers were ruled out. During surgery, primary tumor mass localizad in the right gonad was completely excised. Melanotic peritoneal and hepatic disemination were observed. The patient had left streak gonad and infantile uterus (2 x 3 cm). As gonad dysgenesia was suspected, high resolution cromosomic study was performed and resulted in cariotype 46 XY. Microscopy of the resected gonad showed primary gonad melanoma. Chemotherapy was instituted with no tumor response and the patient died two month later.

Profiling sirolimus-induced inflammatory syndrome: a prospective tricentric observational study.

Directory of Open Access Journals (Sweden)

Fanny Buron

Full Text Available BACKGROUND: The use of the immunosuppressant sirolimus in kidney transplantation has been made problematic by the frequent occurrence of various side effects, including paradoxical inflammatory manifestations, the pathophysiology of which has remained elusive. METHODS: 30 kidney transplant recipients that required a switch from calcineurin inhibitor to sirolimus-based immunosuppression, were prospectively followed for 3 months. Inflammatory symptoms were quantified by the patients using visual analogue scales and serum samples were collected before, 15, 30, and 90 days after the switch. RESULTS: 66% of patients reported at least 1 inflammatory symptom, cutaneo-mucosal manifestations being the most frequent. Inflammatory symptoms were characterized by their lability and stochastic nature, each patient exhibiting a unique clinical presentation. The biochemical profile was more uniform with a drop of hemoglobin and a concomitant rise of inflammatory acute phase proteins, which peaked in the serum 1 month after the switch. Analyzing the impact of sirolimus introduction on cytokine microenvironment, we observed an increase of IL6 and TNFα without compensation of the negative feedback loops dependent on IL10 and soluble TNF receptors. IL6 and TNFα changes correlated with the intensity of biochemical and clinical inflammatory manifestations in a linear regression model. CONCLUSIONS: Sirolimus triggers a destabilization of the inflammatory cytokine balance in transplanted patients that promotes a paradoxical inflammatory response with mild stochastic clinical symptoms in the weeks following drug introduction. This pathophysiologic mechanism unifies the various individual inflammatory side effects recurrently reported with sirolimus suggesting that they should be considered as a single syndromic entity.

To analyse intensity of treatment of high-risk patients with non-ST elevation acute coronary syndromes (NSTEACS) included in the DESCARTES (Descripción del Estado de los Sindromes Coronarios Agudos en un Registro Temporal Español) registry. Patients with NSTEACS (n = 1877) admitted to 45 randomly selected Spanish hospitals in April and May 2002 were studied. Patients with ST segment depression and troponin rise were considered high risk (n = 478) and were compared with non-high risk patients (n = 1399). 46.9% of high-risk patients versus 39.5% of non-high-risk patients underwent angiography (p = 0.005), 23.2% versus 18.8% (p = 0.038) underwent percutaneous revascularisation, and 24.9% versus 7.4% (p or = 4, 2-3 and or = 4 (OR 2.87, 95% CI 1.27 to 6.52, p = 0.012). Class I recommended treatments were underused in high-risk patients in the DESCARTES registry. This undertreatment was an independent predictor of death of patients with an acute coronary syndrome.

The radiological findings of eight patients with the acquired immunodeficiency syndrome (AIDS) who developed bone lesions were analyzed in conjunction with twelve similar published cases. Our series included three patients with lymphoma, two with bacillary angiomatosis, two with tuberculosis and one with staphylococcal osteomyelitis. All the lesions were lithic regardless of the etiology. Both in our cases and in those previously published bone repair was only seen in cases of bacillary angiomatosis treated with erythromycin. No pathognomonic findings were observed. However, the association of skin and bone lesions in immuno deficient patients should always bring the consideration of bacillary angiomatosis in the differential diagnosis. This is particularly relevant since this a condition amenable to treatment once correctly identified. The radiological findings in the lymphoma and tuberculosis patients have not been described previously. (author). 9 refs., 7 figs., 3 tabs.

Apesar da forma de apresentação grave com sintomas desde a infância o diagnóstico foi estabelecido numa idade muito pouco comum. A síndrome de Sturge-Weber é uma entidade a ter presente no diagnóstico diferencial das manchas vinho do porto e das crises convulsivas. O diagnóstico precoce e o seguimento/vigilância médica apertada são as únicas formas de melhorar o prognóstico sombrio das manifestações e complicações desta síndrome que são verdadeiramente limitadoras de autonomia no quotidiano.

Sindrome confusional agudo por abstinencia aguda de nicotina Delirium due to acute nicotine withdrawal

Full Text Available El síndrome confusional agudo (SCA o delirium en pacientes hospitalizados es un problema frecuente y grave. Se caracteriza por síntomas de comienzo agudo y curso fluctuante con inatención, pensamiento desorganizado, y con distintos niveles de alteración de la conciencia.En la bibliografía consultada, el SCA como manifestación de un síndrome de abstinencia aguda nicotínica fue descripto en solo ocho casos. Presentamos el caso de un tabaquista grave que, internado por una reagudización de su enfermedad pulmonar obstructiva crónica (EPOC, presentó un cuadro de SCA al tercer día de abstinencia tabacal, cediendo los síntomas tras la administración de un parche de nicotina. Lo descripto sugiere que en pacientes internados que presentan SCA y agitación, con fuertes antecedentes de tabaquismo, un simple ensayo con un parche de nicotina puede ofrecer en pocas horas una notable respuesta terapéutica y a su vez un test confirmatorio. El reconocimiento del SCA como forma de presentación de la abstinencia nicotínica permitirá identificar casos habitualmente complejos en los que se podrá implementar una sencilla y eficaz alternativa terapéutica.Delirium or acute confusional state among hospitalized patients is a frequent and serious problem. It is characterized by acute onset symptoms, fluctuating course, impaired attention, unorganized thinking, and altered level of conciousness. Delirium, as a manifestation of acute nicotine withdrawal syndrome has been reported in the reviewed literature only in eight cases. We report the case of a heavy smoker admitted because of a reagudization of his chronic obstructive pulmonary disease. At the third day of nicotine abstinence, he developed delirium with a rapid improvement of his symptoms after treatment with a transdermal nicotine patch. This description suggests that in hospitalized heavy smokers who develop delirium with agitation, a simple trial with a nicotine patch can offer a dramatic therapeutic response in a few hours, constituing additionally a confirmatory test. The recognition of delirium as a manifestation of nicotine withdrawal could allow to determine the origin of symptoms and to apply the appropriate therapy, in certain complex cases that now remain undiagnosed.

Full Text Available Accurate and adequate treatment of STIs is a critical component of STI-control activities to reduce transmission and sequelaes. On the other hand, chronic shortage in skilled staff and laboratory equipment in many countries necessitate the use of clinical skills more in order to diagnose and differentiate STIs. For these places, the WHO has recommended and produced a protocol of it syndromic approach management of STIs in place of treatment by -etiology. Since 1997 the Indonesia Ministry of Health has been conducting national training on this method. However, the syndromic approach for vaginal discharge is known to be problematic since differentiation among cervicitis, vaginitis, and even normal condition is difficult. The main objective of this study is to determine the sensitivity, specificity and positive predictive value of the syndromic approach management of women with signs and/or symptoms of abnormal vaginal discharge. The sample population were women with high risk sexual behaviors in East Java and North Sulawesi provinces. The laboratory tests using DNA hybridization probe technique (the PACE 2 test, Gen-Probe, San Diego, Calif. for Neisseria gonorrhoeae and Chlamydia trachomatis were used as gold standard. In addition, we also compared the clinical approach widely used by clinicians (mainly at hospitals with laboratory results. A total of 439 participants was recruited purposively (230 from E. Java and 209 from N.Sulawesi. In E.Java, the sensitivity, specificity, and predictive value of the syndromic management for vaginal discharge are 31%, 83%, and 59%, respectively, and in N.Sulawesi 49%, 56%, and 40%,respectively. The clinical approach did not show better results. In E.Java the sensitivity, specificity, and positive predictive value are 13%, 89%, and 50%, res­pectively, while in N.Sulawesi they are 42%, 61%, and 39%, respectively. As a conclusion, the current form of syndromic management has little use for STI screening among high risk women. Further studies by adding more criteria to the syndromes are needed to improve this method.

2018-04-01

The medial sural artery perforator (MSAP) flap is defined as a thin cutaneo-adipose perforator flap harvested on the medial aspect of the leg. The aims of this study were to describe the anatomical basis as well as the surgical technique and discuss the indications in head and neck reconstructive surgery. We harvested 10 MSAP flap on 5 fresh cadavers. For each case, the number and the location of the perforators were recorded. For each flap, the length of pedicle, the diameter of source vessels and the thickness of the flap were studied. Finally, we performed a clinical application of a MSAP flap. A total of 23 perforators with a diameter superior than 1mm were dissected on 10 legs. The medial sural artery provided between 1 and 4 musculocutaneous perforators. Perforators were located in average at 10.3cm±2cm from the popliteal fossa and at 3.6cm±1cm from the median line of the calf. The mean pedicle length was 12.1cm±2.5cm. At its origin, the source artery diameter was 1.8mm±0.25mm and source veins diameters were 2.45mm±0.9mm in average. There was no complication in our clinical application. This study confirms the reliability of previous anatomical descriptions of the medial sural artery perforator flap. This flap was reported as thin and particularly adapted for oral cavity reconstruction and for facial or limb resurfacing. Sequelae might be reduced as compared to those of the radial forearm flap with comparable results. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Full Text Available Apesar de ter sido relatada anteriormente, a sindrome de Lennox-Gastaut (SLG só foi definitivamente aceita como entidade distinta em 1966. Desde então, o epônimo tem sido utilizado para designar encefalopatia severa da infância, caracterizada fundamentalmente por crises epilépticas refratárias de diversos tipos associadas com alterações eletrográficas típicas. Entretanto, vários autores consideram que o rótulo de SLG está abrigando quadros nosológicos distintos, que deveriam ser separados e individualizados. Ilustrando esta situação, o caso de um paciente que iniciou quadro de «SLG-like» aos 20 anos de idade é relatado. Adicionando mais confusão, alguns casos semelhantes têm sido descritos nos últimos anos sob variada nomenclatura. Desde que um dos principais critérios para o diagnóstico da SLG é a idade dependência, como deverão então ser chamados tais quadros? Revisão dos critérios empregados para o diagnóstico da SLG se faz necessária.

Método: estudo de revisão utilizando critérios de diagnóstico de Sindrome Metabólica em crianças e adolescentes. Resultados e considerações finais: comportamentos como a atividade física, comportamento sedentário e hábitos alimentares possuem sua associação melhor elucidada na literatura, quando comparados aos hábitos de fumo e consumo de álcool, os quais necessitam de maiores investigações nesta população. Contudo, evidências demonstram que todos os hábitos abordados neste trabalho possuem alguma relação com a agregação de fatores de risco metabólicos na idade adulta, e sua prevenção na adolescência parece favorecer o não aparecimento dos mesmos no futuro.

Salah satu komplikasi obesitas adalah kelainan ginjal yang disebut obesity-related renal injury atau gangguan ginjal terkait obesitas. Banyak faktor yang berperan dalam terjadinya obesity-related renal injury. Overweight atau obesitas berhubungan erat dengan berbagai faktor risiko penyakit ginjal kronik yaitu hiperinsulinemia, gangguan metabolisme glukosa, hipertensi, hiperlipidemia, dan sindrom metabolik. Di antara semua faktor tersebut, faktor yang paling berperan antara obesitas dan kerusakan ginjal adalah berkurangnya sensitivitas insulin. Manifestasi klinis  obesity related renal injury biasanya berupa proteinuria bermakna tanpa edema, albumin plasma sedikit menurun, dan kolesterol normal atau sedikit meningkat. Salah satu tata laksana obesity-related renal injury adalah penurunan berat badan. Pengurangan asupan diet dan penurunan berat badan dapat menyebabkan berkurangnya lesi glomerulosklerosis fokal segmental. Terapi lainnya adalah pemberian obat yang memiliki efek negatif terhadap sistem renin-angiotensin seperti inhibitor angiotensin-converting-enzyme dan angitensin receptor blocker.

A 58-year old man was admitted to the hospital because of melena. He had a 1-year history of mechanical aortic valve replacement and coronary stent placement because of myocardial infarction and he was taking warfarin and clopidogrel. Esophagogastroduodenoscopy and colonoscopy were negative for bleeding. Capsule endoscopy showed bleeding diffuse angiodysplasia of the small bowel. The patient was treated with octreotide 20 mg, at monthly interval. After 25 months there had been no recurrence of gastrointestinal bleeding. The case suggests that mechanical valve replacement may not prevent gastrointestinal bleeding in Heyde syndrome and that octreotide treatment should be considered in these cases.

Full Text Available É apresentada uma revisão das recentes aquisições na anemia ancilostomótica, assinalando a importância de alimentação qualitativamente deficiente junto á infestação helmíntica na gênese desta doença. Acentuou-se que a anemia ancilostomótica é uma doença de carência. Profilaxia clássica da Ancilostomose resume-se em evitar a infestação do homem pelos ancilostomídeos. Critica-se a aplicabilidade destas medidas e eficiência das mesmas no que diz respeito á incidência da anemia. O presente trabalho mostra aquisições preliminares sôbre fundamentos de uma profilaxia de carência (tipo profilaxia do bócio endêmico da anemia ancilostomótica, baseada na administração de alimentos contaminados por um sal de ferro. As misturas sulfato ferroso-farinha de mandióca e citrato férrico amoniacal-caldo de feijão, mostraram-se eficientes em prevenir a queda das cifras hemáticas durante largos períodos de tempo em indivíduos maciçamente infestados (6-8 meses. Não foi verificada a dose diária mínima eficiente dêstes sais, obtendo-se resultados satisfatorios mesmo com 0.1 g diária de sulfato ferroso (correspondendo a 0.037 g de ferro metálico. Numerosos alimentos e sais de ferro foram experimentados com resultados infrutíferos por diferentes razões. A influência dos helmintos, pela hemorragias intestinais que acarretam poude ser mais uma vez estudada, nos casos de sais de ferro administrados em doses ineficientes ou em períodos de prova sem medicação marcial. É proposta nova classificação de intensidade de infestação, levando em consideração o conhecido fato de ser a atividade dos helmintos, exclusivamente expoliadora. Em conclusão, nos parece exequível a profilaxia da anemia ancilostomótica mediante ingestão de alimentos contaminados por quantidades eficientes de sais de ferro. Êste método profilático extremamente econômico será na prática, provàvelmente, muito superior aos métodos de profilaxia anti-helmíntica, que além de onerosos são pouco práticos, pois interferem em hábitos enraizados nas populações rurais.A review of the recent advances in the mechanism of hookworm anemia is presented, pointing out the importance of a qualitatively defective nutrition in the genesis of this disease. The carencial aspect of hookworm anemia is emphasized. The accepted prophylaxia of hookworm disease limits itself to avoiding human infestation by the ancylostomidae. This method is criticized as a pratical means of eradicating the anemia in rural population. This paper deals with preliminary studies to build up a carencial type of prophylaxis in hookworm anemia (as in prophylaxis of endemic goitre based on the administration of iron salts, in the food usually consumed in Brazil. The mixtures ferrous sulphate and mandioca flour or amoniacal ferric citrate and baked beans, have been able to prevent anemia in patients heavely infested. during long periods of time (6-8 months. the minimus efficient daily doses of iron needed to maintain normal blood levels have not been precisely ascertained, but even 0.1 g of ferrous sulphate (37 mg of metalic iron daily in mandioca flour was satisfatory for that purpose. Different foods and iron salts have been tried with no results, for different reasons. When iron salts were administered in insufficient doses, the progressive evolution of the anemia was observed in detail. In conclusion the use of iron salts in suficient quantities mixed to usual food is advised as a prophylatic method is hookworm anemia. A campaign of this type can be accomplished at extremely low cost, and probably has definite advantages over the classical prophylaxis, whose methods interferes with rooted habits of people of rural areas and therefore give very poor practical results.

En nuestra revisión hemos encontrado asociación para el desarrollo de Leucemia, P=0.03 con dosis <10 mSv de por vida, Mieloma Múltiple (MM P=0.037, Leucemia Linfoide Crónica ERR: 4.09 Gy 95% CI:<0-14.41. Encontramos que existe asociación significativa entre exposición laboral a radiaciones ionizantes a bajas dosis y el desarrollo de Leucemia y Mieloma Múltiple. Se encontró evidencia de riesgo aumentado de padecer leucemia (excluyendo LLC con tiempo de exposición mayor de 10 años y con dosis promedio de exposición <10 mSv. Existe evidencia en relación a la aparición de trastornos hematopoyéticos radioinducidos en el rango de 55-65 años coincidiendo con los últimos diez años de vida laboral. El hallazgo de una sugerente relación entre LLC y la exposición laboral a bajas dosis de radiaciones ionizantes deja la puerta abierta para futuras investigaciones.

Full Text Available Los trastornos del sueño en niños son frecuentes y afectan el desarrollo neurológico. Los sindromes de apnea obstructiva del sueño y piernas inquietas se destacan por sus efectos cognitivo-conductuales. Los Trastornos del neurodesarrollo, como Autismo, Síndrome Déficit Atención/hiperactividad (TDAH y las co-morbilidades asociadas, presentan alta prevalencia de trastornos del sueño, con dificultades para conciliar el sueño e incremento de los despertares nocturnos, los que frecuentemente pasan desapercibidos para el médico. La consecuencia es una reducción de la alerta para las actividades diarias con incremento de trastornos conductuales, problemas emocionales y dificultades académicas asociadas a disfunción ejecutivas y de memoria, síntomas que pueden empeorar con tratamientos solo para trastorno primario. La evaluación del sueño debe formar parte sistemática en la valoración clínica de los niños con problemas cognitivo-conductuales, con el fin de realizar un diagnóstico y un tratamiento adecuados a cada caso, permitiendo mejorar la calidad de vida del niño y de su familia.

Full Text Available El síndrome de hipermovilidad articular se caracteriza por la presencia de articulaciones con rango de movilidad aumentada, asociada a dolor y deterioro funcional del sistema musculoequelético. Su etiología correspondería a una alteración del colágeno tipo I genéticamente determinada con un patrón de herencia autosómico dominante. Su incidencia es mayor en mujeres y en niños. Se ha descrito asociación con algunos síntomas extraarticulares, por lo cual los síntomas podrían no estar solo limitados al sistema musculoesquelético. El sistema de Beighton es una herramienta útil en definir la condición de hiperlaxitud. Su validación para uso en niños fue publicada por Engelsman y cols el año 2011. No obstante para el diagnóstico de Sindrome de Hiperlaxitud articular sería insuficiente, sugiriéndose el uso del sistema de clasificación de Brighton. Su tratamiento se basa en la educación, estabilización articular global, reeducación postural y de la marcha, mejorar capacidad aeróbica, uso de plantillas y órtesis de pie.

Full Text Available The present investigation sought to establish a relationship between burnout and a number of demographic and organizational variables. The sample consisted of 191 primary school teachers of municipal, subsidized and private educational institutions of Copiapó. The Maslach Burnout Inventory (MBI and the Cuestionario de Evaluación del Sindrome de Quemarse en el Trabajo (CESQT were used as tools to gather information from burnout levels presented by teachers. Two of them demonstrated an adequate reliability and concurrent validity. The results show a statistically significant relationship between absenteeism variable and all dimensions of burnout as measured by both instruments. No statistically significant differences between variables MBI and CESQT compared by sex, type of contract and income level were observed. When comparing the different dimensions of burnout by type of holder, statistically significant differences were detected in all of them. The results favor the private schools, showing the worst results in municipal schools. Alongside this, a negative correlation between levels of emotional exhaustion and psychological wear developed by teams of teachers and the results of the tests SIMCE [Sistema de Medición de la Calidad de la Educación] for second and fourth grade is observed.

Full Text Available Las trombofilias son un grupo de enfermedades que favorecen la formación de trombosis, tanto arteriales como venosas, y han sido asociadas con diferentes complicaciones durante el embarazo, entre las cuales podemos mencionar: aborto recurrente, preclampsia, restricción de crecimiento intrauterino y muerte fetal in útero, entre otras. Recientemente, se ha sugerido una asociación entre trombofilias e infertilidad. Las mutaciones de la enzima Metilentetrahidrofolato Reductasa (MTHFR y de Leiden se encuentran con mayor frecuencia en pacientes con infertilidad de causa desconocida, al compararlas con grupos controles. Durante la etapa de estimulación ovárica diversas trombofilias han sido vinculadas con la aparición de sindrome de hiperestimulación ovárica severo. Por último, las pacientes con historia de falla recurrente de implantación, luego de múltiples ciclos de fertilización in Vitro, demuestran una mayor prevalencia de trombofilias que las pacientes con éxito en dichas terapias. Este artículo presenta una revisión de las publicaciones relevantes que abordaran los distintos aspectos de la relación entre trombofilias e infertilidad hasta agosto de 2009. El objetivo es describir los estudios utilizados y sus implicancias en el manejo de la pareja infértil.

Full Text Available Obiettivo: Lo scopo di questo studio è stato valutare la produzione di TNF-α, induttore della via estrinseca del processo apoptotico, in seguito al trattamento con gli autoanticorpi anti-Ro ed anti-La isolati da pazienti con sindrome di Sjögren primaria in un modello sperimentale rappresentato dalla linea cellulare di ghiandole salivari umane, A- 253. È stata, inoltre, valutata la presenza sulla superficie di tali cellule di recettori specifici per tale induttore, TNFR1 e TNFR2. Materiali e metodi: Gli autoanticorpi anti-La ed anti-Ro sono stati purificati su una colonna cromatografia ad alta affinità. Le metodiche utilizzate per la valutazione della produzione di TNF-α e lo studio dei recettori di superficie sono state immunofluorescenza, RT-PCR e saggi immunoenzimatici. Risultati: I nostri risultati hanno dimostrato che le cellule A-253 esprimono in superficie i recettori TNFR1 e TNFR2 e che gli autoanticorpi anti-Ro e anti-La sono in grado di indurre la produzione di TNF-α nelle stesse cellule. Conclusioni: Il trattamento con gli autoanticorpi anti-Ro ed anti-La induce la produzione di TNF-α in cellule di ghiandole salivari umane e questo potrebbe spiegare la attivazione della via estrinseca della apoptosi.

The efficacy of radiation therapy for feline advanced cutaneous squamous cell carcinoma was evaluated. A full course radiation therapy protocol was applied to six cats showing single or multiple facial squamous cell carcinomas, in a total of seven histologically confirmed neoplastic lesions. Of the lesions, one was staged as T{sub 1}, and six as T{sub 4} according to WHO staging system of epidermal tumors. The animals were submitted to twelve radiation fractions of 4 Gy each, on a Monday-Wednesday-Friday schedule, and the equipment used was an orthovoltage unit. Energy used was 120 kV, 15 mA and 2 mm aluminum filter. The cats were evaluated during the treatment and 30 and 60 days after the end of the radiation therapy. In this study, 87% of the lesions had complete remission and 13% partial remission to the treatment. Side effects were considered mild according to Veterinary Radiation Therapy Oncology Group Toxicity criteria, and included erythema, epilation and rhinitis. Radiation Therapy was considered safe for feline cutaneous squamous cell carcinoma, leading to mild side effects and can represent a good therapeutic option. (author)

A maioria dos pacientes apresenta elevação acentuada dos níveis tensionais outros, níveis moderados ou normais. Os sintomas são progressivos e compreendem cefaléia, diminuição do nível de consciência, crises epilépticas e distúrbios visuais. A sintomatologia regride completamente se corrigidas em tempo as causas determinantes, caso contrário, podem instalar-se danos irreversíveis como a cegueira cortical e morte. A tomografia computadorizada (TC e, sobretudo, a ressonância magnética (RM contribuem para o diagnóstico. Tais métodos evidenciam edema da substância branca e cinzenta, principalmente das regiões parieto-occipitais. Os achados podem apresentar dificuldade no diagnóstico, hoje superado em parte, com a técnica de difusão pela RM, capaz de diferenciar edema citotóxico de vasogênico. Apresentamos um caso de encefalopatia posterior reversível decorrente de encefalopatia hipertensiva estudada com TC e RM.The posterior reversible leukoencephalopathy syndrome (PRES is a recently proposed cliniconeuroradiologic entity.The most common causes of PRES are hypertensive encephalopathy, eclampsia, cyclosporin A neurotoxicity and the uremic encephalopathies.Most patients are markedly hypertensive at presentation, although some have only middly elevated or even normal blood pressure. Symptoms may include headache, nausea , vomiting, altered mental status, seizures,stupor, and visual disturbances. On CT and MR studies, edema has been reported in a relatively symmetrical pattern, typically in the subcortical white matter and occasionally in the cortex of the occipital and parietal lobes. These often striking imaging findings usually are resolved on follow-up studies obtained after appropiate therarapy. Diffusion-weighted images would not show hyperintense signal because of the presence of interstitial rather than cytotoxic edema. We report a case of PRES due to hipertensive encephalopathy studied by CT and MRI.

Sobre la concepcion del sindrome piramidal y del componente yuxtapiramidal despues de 21 años

Directory of Open Access Journals (Sweden)

Luis Barraquer-Bordas

1973-12-01

Full Text Available Tal como hemos venido manteniendo desde 1952, nos parece justo distinguir dentro del todo del sndrome piramidal un aspecto, diferenciado con suficiente claridad, al que propusimos llamar "yuxtapiramidal". Una nomenclatura científica es, ante todo, un sistema de convenciones — lo más fundamentadas que sea posible — sobre las que es necesario mantener un acuerdo para extraer de ella una utilidad operativa. El término "piramidal" no es mucho más inexacto que muchos otros empleados en Medicina. Ciertamente, si queremos tomar por referencia la palabra ecológicamente originaria, que en este caso es la pirámide bulbar, las dificultades aparecen como serias y considerables. Pero si tenemos en cuenta que a la proyección piramidal pura u ortopiramidal o córtico-espinal directa, va estrechamente aparejado el sistema anátomo-funcional que parece ser crucial en la inhibición del reflejo miotático o de tracción, esto es, la proyección córtico-bulbo(retículo-espinal, que nosotros venimos calificando (desde 1952 de "proyección yuxtapiramidal", facilmente nos daremos cuenta que ambos forman un todo, dispuesto longitudinalmente a lo largo del neuroeje, que mantiene una indudable unidad funcional, sobre todo una "unidad de afectación ante los procesos morbosos que los atañen". La dificultad de la nomenclatura proviene, en gran parte, del hecho de haber querido denominar un "sistema longitudinal" por el nombre de un "accidente casi-transversal" interpuesto en un punto determinado y concreto de su curso: la pirámide bulbar, la cual parece abarcar solamente el "componente mayor" de aquel sistema, con exclusión del otro, del yuxtapiramidal". Las aportaciones experimentales recientes de Asbhy y col. y del grupo de Lance, al confirmar lo esencial de las viejas experiencias de Magoun e col., otorgan, a nuestro juicio, una validez renovada a nuestra concepción de un "sistema yuxtapiramidal", inhibidor del reflejo de tracción. De la afectación de las funciones de este sistema derivarian la espasticidad y la exaltación de los reflejos musculares clinicos. El modo como ello tiene lugar parece ser muy complejo y aún variable de unos a otros casos. Habiendo dedicado a esta cuestión otros estudios recientes de revisión (1972, 1973, no hemos querido entrar aqui en esta materia. Pero si que queremos concluir reafirmando que sigue pareciendonos útil emplear todavia el término de "síndrome piramidal" siempre y quando se tenga en cuenta lo que dentro de él traduce la interferencia del "componente yuxtapiramidal", cuya afectación aislada no encontramos nunca o casi nunca en clínica humana. Una actitud como la que proponemos es, evidentemente, una suerte de "compromisso", pero el progreso de la ciencia clínica está montado, en gran parte, sobre compromisos de esta índole. Y nadie pretende que sean "definitivos".

The treatment of arterial hypertension (AH) in patients with metabolic syndrome (MS) is a challenge, since non drug therapies are difficult to implement and optimal pharmacological treatment is not fully established. To assess the blockade of the rennin angiotensin aldosterone system (RAAS) in blood pressure (BP) in renal function and morphology in an experimental model of MS induced by high fat diet. Wistar rats were fed on high fat diet from the fourth week of life, for 20 weeks. The groups received Losartan or Spironolactone from the eighth week of life. We weekly evaluated the body weight and BP by tail plethysmography. At the end of the experiment oral glucose tolerance, lipid profile, creatinine clearance tests, and the direct measurement of BP were performed. A morphometric kidney analysis was performed. The administration of high-fat diet was associated with the development of MS, characterized by central fat accumulation, hypertension, hyperglycemia and hypertriglyceridemia. In this model there were no changes in renal histomorphometry. The blockade of angiotensin II (Ang II) receptor AT1 prevented the development of hypertension. The mineralocorticoid blockage did not have antihypertensive efficacy but was associated with reduction of abdominal fat. The dissociation of the antihypertensive response to the blockades of Ang II receptors and mineralocorticoid indicates the involvement of Ang II in the pathogenesis of hypertension associated with obesity. Reduction of central obesity with Spironolactone suggests the presence of mineralocorticoid adipogenic effect.

Full Text Available Munchausen syndrome is a complex type of abuse, which is often underdiagnosed or misdiagnosed in clinical practice, and has harmful consequences for children. Its relationship with child abuse, of which it is a variety, must be recognized in clinical and forensic practice. The authors report herein two observed cases of different types of Münchausen syndrome by proxy (MSbP. The first, is the most severe form of MSbP, with induced, true illness and related pathological symptoms into victim. The second case is a moderate form, much more complex to detect, in which a perpetrator parent simulates and aggravates the child‘s illness. Adequate training of health professionals and investigators is essential in revealing cases of MSbP. Diagnosis must be based on the study of the different forms of "abuse" and the knowledge of clinical protocols used to validate any suspected behaviour which could be potentially harmful to the child. Moreover, a lack of training may lead to misleading interpretations of medical history interpretation and fallacious conclusions. Our study aims to review the features that are to be considered in a suspected case of MSbP, in accordance with a recently updated consensus statement by the Committee on Child Abuse and Neglect from the American Academy of Pediatrics.

The inadequate reporting of cross-sectional studies, as in the case of the prevalence of metabolic syndrome, could cause problems in the synthesis of new evidence and lead to errors in the formulation of public policies. To evaluate the reporting quality of the articles regarding metabolic syndrome prevalence in Peruvian adults using the STROBE recommendations. We conducted a thorough literature search with the terms "Metabolic Syndrome", "Sindrome Metabolico" and "Peru" in MEDLINE/PubMed, LILACS, SciELO, LIPECS and BVS-Peru until December 2014. We selected those who were population-based observational studies with randomized sampling that reported prevalence of metabolic syndrome in adults aged 18 or more of both sexes. Information was analysed through the STROBE score per item and recommendation. Seventeen articles were included in this study. All articles met the recommendations related to the report of the study's rationale, design, and provision of summary measures. The recommendations with the lowest scores were those related to the sensitivity analysis (8%, n= 1/17), participant flowchart (18%, n= 3/17), missing data analysis (24%, n= 4/17), and number of participants in each study phase (24%, n= 4/17). Cross-sectional studies regarding the prevalence of metabolic syndrome in peruvian adults have an inadequate reporting on the methods and results sections. We identified a clear need to improve the quality of such studies.

Estar conectado la mayor parte del día a redes sociales motiva la obsesión por los autorretratos o más conocidos como “Selfies”, dando origen al moderno “Síndrome de Selfie”. Este trabajo presenta un modelo de minería de datos elaborado con el programa RapidMiner para el análisis de sentimientos que permitió clasificar el efecto emocional (positivo / negativo de los comentarios publicados en 250 “Selfies” de hombres y 250 “Selfies” de mujeres en la red social Facebook. Con el modelo se concluye que existe una fuerte correlación entre la necesidad de reconocimiento y “Sindrome de Selfie”, la cual varía en función del género. Según el modelo desarrollado es mayor en el femenino, rxy = 0.75, que en el masculino, rxy = 0.61, lo que permite afirmar que el grado de relación o de asociación entre las dos variables es buena para el género femenino a diferencia del masculino, lo que indica que las mujeres constantemente están bajo una presión social estética mucho mayor que los hombres.

Objective: To evaluate the reporting quality of the articles regarding metabolic syndrome prevalence in Peruvian adults using the STROBE recommendations. Methods: We conducted a thorough literature search with the terms "Metabolic Syndrome", "Sindrome Metabolico" and "Peru" in MEDLINE/PubMed, LILACS, SciELO, LIPECS and BVS-Peru until December 2014. We selected those who were population-based observational studies with randomized sampling that reported prevalence of metabolic syndrome in adults aged 18 or more of both sexes. Information was analysed through the STROBE score per item and recommendation. Results: Seventeen articles were included in this study. All articles met the recommendations related to the report of the study's rationale, design, and provision of summary measures. The recommendations with the lowest scores were those related to the sensitivity analysis (8%, n= 1/17), participant flowchart (18%, n= 3/17), missing data analysis (24%, n= 4/17), and number of participants in each study phase (24%, n= 4/17). Conclusion: Cross-sectional studies regarding the prevalence of metabolic syndrome in peruvian adults have an inadequate reporting on the methods and results sections. We identified a clear need to improve the quality of such studies. PMID:26848197

Teorijske refleksije o mogućim uzrocima inertnosti egalitarnog sindroma

Full Text Available Jedna od osnovnih postavki teorije egalitarnog sindroma Josipa Županova, postavka o egalitarnom sindromu kao klasteru naslijeđenih neformalnih normi, kompatibilna je s nekoliko teorijskih koncepata kulturne inercije. Iz perspektive teorija ovisnosti o prijeđenom putu perzistencija egalitarnog sindroma može se objasniti djelovanjem faktora odgovornih za reprodukciju društvenih normi. Riječ je o faktorima koji ne utječu na genezu određenoga društvenog fenomena (primjerice, normi, nego ga kroz vrijeme reproduciraju. Shodno rezultatima recentnih empirijskih istraživanja, jedan od reprodukcijskih faktora egalitarnog sindroma može se pronaći u tranzicijskim troškovima. Na osnovi toga, kao i propozicije o razlikovanju generativnih od reprodukcijskih faktora društvenih fenomena, legitimiramo tezu da tranzicijski troškovi nisu stvorili egalitarni sindrom, nego su pridonijeli njegovoj perzistenciji i u postsocijalističkom društvenom kontekstu. Moguće izvore hipoteza o dodatnim čimbenicima reprodukcije egalitarnog sindroma u tranzicijskim okolnostima pruža koncept kulturne inercije svojstven teorijskoj perspektivi institucionalizma, teorija kulturne evolucije Roberta Boyda i Petera J. Richersona, kao i koncept zapinjača Michaela Tomasella. Također, sukladno ideji o »efektu tunela« Alberta Hirschmana, možemo pretpostaviti da je očekivana stagnacija u društvenoj pokretljivosti jedan od mogućih specifičnih faktora reprodukcije egalitarnog sindroma.

The authors report the findings of Aicardi syndrome, a disease of unknown etiology composed of multiple spasms, chorioretinal lacunae and agenesis of the corpus callosum. They present a case of Aicardi syndrome with characteristic clinical presentation and magnetic resonance imaging findings. The disease, despite being considered rare, has characteristic imaging findings. Over the past years magnetic resonance imaging has improved its ability in demonstrating other findings besides agenesis of the corpus callosum, making the radiologist's role very important in the diagnostic suspicion of this disease.

Full Text Available Os Autores descrevem um caso grave de esquistossomose mansoni (forma hepática com hipertensão portal associada a forma pulmonar com hipertensão pulmonar e cor pulmonalej sobre o qual evoluiu uma sindrome toxi-infectuosa grave e de longa duração. Sucessivos exames radiológicos do tórax revelaram acometimento predominantemente arteriolar, ao lado de uma micronodulação pulmonar grosseira e difusa em ambos os hemitóraces e configuração de coração pulmonar. A histopatologia de material de biópsia pulmonar identificou basicamente uma arterite pulmonar característica, inflamação granulomatosa atípica provocada principalmente por vermes e raros ovos de S. mansoni envolvidos por escassa reação inflamatória. Para explicar a origem de constelação clínica toxi-infectuosa, foram afastadas as hipóteses de associação da esquistossomose a concausas infectuosas ou não, mas de curso febril, e a superposição de uma forma toxêmica sobre outra crônica pré-existente. Com base em dados clínicos, particularmente em subsídios da laparoscopia, e anatômicos, concluiu-se tratar o caso de uma forma crônica de esquistossomose reativada, provavelmente em virtude de alterações imunológicas inusitadas do hospedeiro. Ao que tudo parece indicar, o desvio de ovos e de vermes aos pulmões deveu-se à sindrome de hipertensão portal, cujos shunts entre a circulação portal e sistêmica determinaram a rota preferencial da migração.The Authors relate a case ofsevere schistosomiasis mansoni (hepatic form, with portal hypertension, associated with pulmonary form, with pulmonary hypertension and cor pulmonale, o ver which develloped a severe toxi-infectious syndrome of long duration.

Full Text Available El deterioro cognitivo leve es una entidad caracterizada por el compromiso predominante de la memoria en ausencia de trastorno funcional. Ha sido asociado a un período predemencial de la enfermedad de Alzheimer. Sin embargo, se considera que otras áreas cognitivas pueden verse afectadas, pudiendo implicar también otras etiologías. Así, algunos profesionales lo consideran un término etiológico, dirigido hacia la enfermedad de Alzheimer y otros un complejo sindromático, incluyendo varias enfermedades. Otro factor agregado que generó confusión ha sido el porcentaje de conversión a demencia. El objetivo de nuestro trabajo fue evaluar la opinión médica sobre el deterioro cognitivo leve y los problemas que genera en la práctica diaria. Se adaptó el cuestionario sobre deterioro cognitivo leve de Dubois y col, 2003; 24 médicos expertos en demencia de Argentina y Brasil (16 neurólogos y 8 psiquiatras y 30 médicos generalistas aceptaron responder al mismo. Los resultados muestran que el 92% de los médicos expertos piensa que es una entidad heterogénea, no la limitan a un estadio predemencia de la enfermedad de Alzheimer; y el 63% refieren que puede empeorar. El 83% de los expertos inician tratamiento específico utilizando preferentemente anticolinesterásicos, memantine y vitamina E. La vasta mayoría de médicos considera al deterioro cognitivo leve como una entidad sindromática, que no está limitada a la enfermedad de Alzheimer; pero sin embargo, inicia tratamiento con drogas dirigidas hacia ella. La ambigüedad existente hace necesario estandarizar definiciones y reconceptualizar la enfermedad de Alzheimer en su estadio pre-demencia.Mild cognitive impairment (MCI refers to persons who are slightly cognitively impaired for age but do not meet the criteria for dementia. MCI has been related to a pre-dementia stage of Alzheimer&'s disease (AD. However, other possible diagnoses such as cerebro-vascular disease, frontotemporal

The polycystic ovarian syndrome is the most frequent endocrine affection in females at reproductive age. Nowadays, it is known that insulin resistance and consequent hyperinsulinism seem to be the basis of the disorders characterizing it. That's why, it is not erroneous to think that in females with metabolic syndrome, whose physiopathological bases are insulin resistance and hyperinsulinism, there may appear clinical, humoral and ultrasonographic elements of the polycystic ovarian syndrome.

Full Text Available The first International Classification of Diseases (ICD was approved in 1893 and since then it has been periodically reviewed. The last, 10th revision (ICD-10, was approved in 1989. Since 1989, it was possible to update from ICD revisions, which did not happen before. The next revision (ICD-11 would probably be published in 2015. In 1989, mechanisms were established to update ICD-10, through the creation of the Morbidity Reference Group (MbRG in 1997 and the Update and Revision Committee (URC in 2000. The Morbidity Reference Group (MbRG was created in 2007 to discuss in more detail the issues to update morbidity. A specific code in ICD was not included in the revision of ICD-10 in 1989 for the post-polio syndrome (PPS. However, the ICD new code G14 for PPS was included in ICD-10 since 2010.

Full Text Available RESUMEN:Estudios recientes, relacionan el SAHS con mayor morbimortalidad cardiovascular y por otro lado, sabemos que aún hoy en día, el SAHS sigue estando infradiagnosticado. Este infradiagnóstico supone, por un lado, un déficit o perdida de salud y por otro lado, un aumento de costes, ya que está demostrado que los pacientes con SAHS no diagnosticados ni tratados, son mayores consumidores de los servicios de salud y presentan mayor absentismo laboral, mientras que estos costes se reducen en los pacientes con SAHS tratados con CPAP. Por tanto, nos encontramos ante la necesidad de diagnosticar y tratar adecuadamente al mayor número posible de pacientes que padezcan un SAHS.El método diagnóstico de elección, sigue siendo la PSG nocturna vigilada en el laboratorio de sueño, sin embargo, el futuro del diagnóstico del SAHS pasa indefectiblemente por el empleo de sistemas simplificados con alta sensibilidad y especificidad. En este sentido, la Poligrafía Respiratoria, representa una alternativa útil para el diagnóstico del SAHS, pudiendo ser realizada en el domicilio del paciente, al igual que los sistemas Auto-CPAP. De esta forma, el abordaje actual del SAHS ha cambiado y así, un paciente con alta probabilidad de padecer un SAHS, se le puede realizar una PR domiciliaria que diagnostique el SAHS y posteriormente para ajustar el nivel de presión óptima de CPAP, se le podría hacer un registro domiciliario de Auto-CPAP.Con este nuevo abordaje del SAHS, se podrán disminuir las listas de espera y por tanto disminuir el infradiagnóstico. Todo ello conlleva implícitamente un ahorro de recursos. El lugar del diagnóstico, será fundamentalmente el domicilio, y en este sentido, el desarrollo de aplicaciones telemáticas contribuirá de forma importante a la modificación de las estrategias diagnósticas.El éxito de esta forma de abordaje del SAHS, vendrá marcado por una adecuada selección de los pacientes subsidiarios de diagnóstico y ajuste de tratamiento domiciliario, por lo cual, cada unidad de sueño debe establecer su propia estrategia diagnóstico-terapeútica que resulte más costo-efectivaSUMMARYThe recent studies relate the Sleep Apnea/Hipopnea Syndrome (SAHS with cardiovascular morbidity and mortality, and today, we know it is an underdiagnosed disease. This underdiagnostic implies unhealthy and it increases of health care utilization because the patients with SAHS neither diagnostic nor treatment, they are increase health care utilization and they are more absentees work, whereas the Continuous Positive Airway Pressure (CPAP treatment significantly reduces health care utilization. So, we must diagnose and we must treat the patients with SAHS.The nocturnal polysomnography (PSG is still the diagnosis technique considered as "Gold Standard", although in the future, the diagnosis of SAHS will be to do it with simplifies systems with highly sensitivity and with highly specificity. The Respiratory Polygraphy (RP is a useful option for diagnosis of SAHS and the Respiratory Polygraphy and the auto-CPAP system could be makes at home. In this moment, when we find a patient with highly probability to have SAHS, we could make a Respiratory Polygraphy at home for diagnosis of SAHS and then, we could make auto-CPAP for titration the optimum level of CPAP pressure.With this approach, we will reduce the underdiagnostic and the waiting list, and then saving resources. The place of diagnosis will be at home and then the telematic development will aid to modify the diagnostic approach.This approach's success for diagnose of SAHS will be determinate for the patients´s suitable selection, so every sleep unit must set up its diagnostic-treatment approach that results more cost-effective

Mutações no gene da metilenotetrahidrofolato redutase e síndrome de Down

Full Text Available Sindrome de Down (SD é uma alteração genética e metabólica complexa atribuída à presença de três cópias do cromossomo 21. O cromossomo extra em 93% dos casos é de origem materna e é resultante de uma segregação anormal durante a meiose (não-disjunção. Com exceção da idade materna avançada, fatores de risco para a não-disjunção meiótica não estão bem estabelecidos. Um estudo preliminar sugeriu que o metabolismo anormal do folato e a mutação 677 (C->T no gene da metilenotetrahidrofolato redutase (MTHFR podem ser fatores de risco maternos para a SD. A freqüência das mutações MTHFR 677 (C->T e 1.298 (A->C foram avaliadas em 36 mães de crianças com SD e em 200 indivíduos-controle. Os resultados demonstraram que as mutações 677 (C->T e 1.298 (A->C são mais prevalentes entre mães de crianças com SD do que nos controles. A heterozigose das duas mutações foi a combinação mais freqüente. O resultado desse estudo inicial sugere que mutações no gene da MTHFR seriam um fator de risco para a SD.

The problems associated with medical cases of functional tissue loss or organ failure are destructive and expensive, even more frequent than could be perceived, sometime if not properly treated, even deathly. Tissue engineering is an interdisciplinary field that emerged to address these clinical problems, it is based on researching and development of biomaterials that have evolved along with areas such as cell biology, molecular and materials science and engineering. Today, the technique is based on seeding cells onto prefabricated scaffold biomaterials, like the hydrogels, that are three-dimensional networks with hydrophilic properties. These materials are characterized as being porous and sticky, favoring the support for the proliferation of certain cells in order to lead the regeneration of injured tissue. As a prerequisite for the use of materials in tissue engineering is testing biocompatibility which is the ability of the bio material to allow contact with any tissue, existing a favorable host response, accepting it as their own and restoring previously lost function. The first step for evaluating biocompatibility is to perform the in vitro assays. These assays have been demonstrated more reproducibility and predictability than in vivo assays, therefore the in vitro assays are used to produce high quality scaffolds and testing on animals as less as possible. This test is essential to establish the benefits and limitations of biomaterials tested in order to improve the scaffolds. This work will focus on assessing the biocompatibility of three polymeric materials with potential use in tissue engineering by means of cytological compatibility tests and hemo compatibility tests. Furthermore, disinfection techniques and gamma sterilization were evaluated to produce sterile materials that can be used in tissue engineering. (Author)

Hallervorden-Spatz syndrome is a neuro degenerative disease, autosomic recessive with two clinical features: early and late onset. Psychiatric, pyramidal and extrapyramidal signs are present in the late subtype. We report the case of a 41-old woman with extrapyramidal signs. Magnetic resonance imaging (MRI) showed the eye-of-the-tiger sign in the medial globus pallidus. This is due to a gliosis (increased signal) and accumulation of surrounding iron (decreased signal intensity) in long T R sequences. There is a strong relationship between MRI findings and the gene mutation responsible for this disease. It makes the MRI sensible for diagnosing this syndrome. (author)

The objective of this study was to review the magnetic resonance imaging findings in patients with Hallervorden-Spatz syndrome. We evaluated eight patients with Hallervorden-Spatz syndrome using magnetic resonance imaging. The protocol included at least sagittal and axial T1-weighted images and axial and coronal T2-weighted images. Intravenous gadolinium was administered in a dose of 0.1 mmol/kg. Post-enhanced images were obtained at least in the axial and coronal planes. The results were: all patients presented a bilateral and symmetrical 'tiger-eye signal' on T2-weighted images, corresponding to central hyperintensity and peripheral hypointensity in the globi pallidus. FLAIR and diffusion images showed similar abnormalities. There was no gadolinium enhancement in any of the cases. We concluded that magnetic resonance imaging findings in patients with Hallervorden-Spatz syndrome are very typical and allow the diagnosis of the disease. (author)

Dysmenorrhea is a menstrual disorder with the greatest prevalence followed by premenstrual syndrome that includes physical and psychological symptoms. Micronutrients intake of calcium and magnesium can help overcome these complaints. This research was conducted to find out the effect of calcium and magnesium supplements consumption on dysmenorrhea and premenstrual syndrome symptoms in 19–23 years old women. This was quasi experimental research with pre- and post-test design. The research was conducted in Maranatha Christian University Bandung from July to December 2016. The subjects of research were 60 women aged 19–23 years old, divided into two groups randomly. One group given calcium (1,000 mg/day or magnesium (250 mg/day, which was given at the second day of menstruation until the next menstrual cycle. Serum levels of calcium or magnesium were measured with spectrophotometry method. Dysmenorrhea was measured with visual analog scale (VAS, whereas score of premenstrual syndrome was measured with shortened premenstrual assessment form, before and after treatment. The consumption of calcium lowers the VAS score average on dysmenorrhea from 6.97 to 3.80 (p=0.000** and the mean score of premenstrual syndrome from 15.07 to 10.80 (p=0.000**. Consumption of magnesium reduces the VAS score average on dysmenorrhea from 7 to 4 (p=0.000** and the mean score of premenstrual syndrome from 12.27 to 9.87 (p=0.001**. In conclusion, consumption of calcium or magnesium supplements reduce dysmenorrhea and premenstrual syndrome in women aged 19–23 years old.

The aim of this study was to investigate cognitive functioning and insight of illness in two groups of patients during their stable phases, one with schizophrenia and one with schizoaffective disorder. We recruited 104 consecutive outpatients, 64 with schizophrenia, 40 with schizoaffective disorder, in the period between July 2010 and July 2011. They all fulfilled formal Diagnostic and Statistical Manual of Mental disorders (DSM-IV-TR) diagnostic criteria for schizophrenia and schizoaffective disorder. Psychiatric assessment included the Clinical Global Impression Scale-Severity (CGI-S), the Positive and Negative Sindrome Scale (PANSS), the Calgary Depression Scale for Schizophrenia (CDSS) and the Global Assessment of Functioning (GAF). Insight of illness was evaluated using SUMD. Neuropsychological assessment included Winsconsin Card Sorting Test (WCST), California Verbal Learning Test (CVLT), Stroop Test and Trail Making Test (TMT). Differences between the groups were tested using Chi-square test for categorical variables and one-way analysis of variance (ANOVA) for continuous variables. All variables significantly different between the two groups of subjects were subsequently analysed using a logistic regression with a backward stepwise procedure using diagnosis (schizophrenia/schizoaffective disorder) as dependent variable. After backward selection of variables, four variables predicted a schizoaffective disorder diagnosis: marital status, a higher number of admission, better attentive functions and awareness of specific signs or symptoms of disease. The prediction model accounted for 55% of the variance of schizoaffective disorder diagnosis. With replication, our findings would allow higher diagnostic accuracy and have an impact on clinical decision making, in light of an amelioration of vocational functioning.

Morgagni-Larrey hernia (MH) is an unusual diaphragmatic hernia of the retrosternal region. Few cases of MH, treated laparoscopically, associated with Down's syndrome (DS) have been reported in literature. On October 2004, a DS 40-year-old male was admitted to our Department with mild abdominal pain and nausea. Hematochemical tests were within the normal range. Ultrasonography showed biliary sludge and multiple gallstones. Chest X-ray revealed a right-sided paracardiac mass that appeared as MH after a thoraco-abdominal computed tomography (CT). Four trocars were placed as a routinary cholecystectomy. Abdominal exploration confirmed the presence of a voluminous hernia through a wide diaphragmatic defect (12 cm) on the left side of the falciform ligament, containing the last 20 cm ileal loops and right colon with the third lateral of transverse. After retrograde cholecystectomy and reduction of the herniated ileo-colonic tract from multiple adherences, the defect was repaired with an interrupted 2/0 silk suture and then a running 2/0 polypropylene suture. Postoperative course was complicated by pulmonary edema but subsequently the patient was discharged without further complications and has no recurrence after 2 years. In conclusion, surgery is necessary for symptomatic MH and to prevent possible severe complications. We preferred laparoscopy for the reduced morbidity compared to laparotomy, even if in our case the postoperative course was not uneventful. There are still few comparative data about the modality of closure of the defect between primary repair with nonabsorbable suture material, in case of small defects, or continuous monofilament suture or prosthesis in case of large defects.

Contribuciones tecnicas para la medida de la contaminacion electromagnetica de microondas. Estudio en diversas poblaciones

Science.gov (United States)

Segura Garcia, Jaume

La contaminacion ambiental por campos electromagneticos ha resultado ser en estos ultimos anos uno de los problemas mas acuciantes del panorama tecnologico y de salud publica. En el primero de los casos porque las inversiones realizadas son enormes y en el segundo porque cada vez es mayor el numero de articulos, "technical reports" e informes medicos que afirman la existencia de una cierta causalidad, aunque sea debil, entre los campos electromagneticos y ciertos cuadros sintomatologicos. En nuestro caso, hemos dedicado bastantes esfuerzos a investigar el llamado "sindrome de radiofrecuencia / microondas", denominado asi en la literatura cientifica por presentarse en operarios de estaciones de radar y en trabajadores de potentes emisoras de radio y television. En esta memoria presentamos un resumen del trabajo realizado durante los ultimos anos en la medida de la contaminacion electromagnetica ambiental asociado a las comunicaciones inalambricas. En ella se recogen los fundamentos fisicos y propiedades de las ondas electromagneticas, la tecnologia empleada en los sistemas de telefonia celular y los antecedentes relativos a la investigacion de la interaccion de las ondas electromagneticas con organismos vivos. Se desarrolla un procedimiento de medida que ha conducido a la elaboracion de los primeros "mapas de radiofrecuencia" similares, en el aspecto descriptivo, a los mapas de ruido desarrollados en el area de la contaminacion acustica. Por ultimo, se analiza la respuesta subjetiva de los residentes, personas que viven en el entorno de cobertura de las estaciones base de telefonia movil y que se ven sometidos a determinados niveles de radiacion electromagnetica, con el fin de situar este fenomeno al nivel que le corresponde en el ambito de la respuesta subjetiva ciudadana.

produccion de apoptosis en un modelo experimental de irradiacion prenatal. Se irradiaron cultivos primarios de cerebro (rata Wistar, dia 15 de e.g.), en un rango de dosis hasta 2 Gy (Cobalto 60). Se evaluo la respuesta a la incubacion con distintos neuroprotectores. Se estudiaron los siguientes parametros: alteraciones de la morfologia celular, fragmentacion de cromatina y fraccion de celulas apoptoticas. Las celulas irradiadas mostraron condensacion nuclear con presencia de cuerpos apoptoticos. Las corridas electroforeticas evidenciaron un patron de fragmentacion caracteristico ('laddering') con aumento dosis-dependiente en la fraccion de celulas apoptoticas analizadas por citometria de flujo. La incubacion con neuroprotectores no indujo cambios significativos en las concentraciones y los tiempos ensayados. Se analizan los resultados obtenidos. Se discute acerca del rol de la apoptosis, su relacion con la injuria oxidativa y los fenomenos de excitotoxicidad como mecanismo de danio radioinducido en el sistema nervioso central en desarrollo.

Lemierre's syndrome is a type of sepsis caused by anaerobes that is secondary to a pharyngotonsillar infection complicated by suppurative thrombophlebitis of ipsilateral jugular vein and septic emboli. Imaging studies are valuable tools for confirming the diagnosis. Chest x-ray reveals poorly defined cavitated, peripheral, nodular lesions. computed tomography (CT) is useful in confirming the pulmonary lesions, which are suggestive of septic emboli. Doppler ultrasound of the neck plays and indispensable role in demonstrating the internal jugular vein thrombosis. We report the case of patient who presented the characteristic clinical and radiological features of Lemierre's syndrome. (Author) 17 refs.

The authors report two cases of bronchogenic carcinoma in patients with acquired immunodeficiency syndrome. The first patient, a ee-year-old male, developed a left hilar adenocarcinoma, with spleen and bilateral adrenal metastases. The disease progressed unfavourably, resulting in the patient's death in less than a month. The second patient, a 47-year-old male, developed a large mass in the left upper lobe, with invasion of the thoracic wall and destruction of adjacent ribs. The histopathologic study revealed a non-oat-cell carcinoma. Both patients received palliative treatment since diagnosis was established late in the course of the disease. Recent studies suggest an association between bronchogenic carcinoma and human immunodeficiency virus infection. However, an actual increase in the prevalence of bronchogenic carcinoma in HIV-positive patients remains controversial. (author)

Churg-Strauss syndrome, a necrotizing systemic vasculitis which involves the small and (more rarely) the medium-sized vessels, is a primary vasculitis strongly associated with anti neutrophil cytoplasm antibodies (ANCA). It is characterized by the presence of asthma, eosinophilia and extravascular eosinophilic granulomas. Herein, we report a 36-year-old woman with a history of late onset asthma and allergic rhinitis who developed central nervous system involvement, peripheral neuropathy, leucocytoclastic vasculitis and eosinophilia. Interestingly, unusual clinical manifestations of Churg-Strauss syndrome such as mesenteric micro aneurysms and jaw claudication were present in this particular patient. A brief review of the literature of Churg-Strauss syndrome is presented.

Se pone énfasis en los aspectos de mayor potencialidad integradora de sus desarrollos teóricos, tales como la evolución biosocial de la persona (expuesta en su primera teoría, en la que ya incluía dos polaridades: actividad versus pasividad; sí mismo versus otros, las posteriores consideraciones destinadas a enriquecer el modelo de persona, mediante la incorporación de una nueva polaridad, placer-dolor, la resignificación de las etapas vitales que figuraban en su teoría originaria y la interrelación entre áreas estructurales y áreas funcionales de la personalidad. Se puntualizan los aportes incorporados por Millon a la práctica de la evaluación psicológica y psicopatológica, desde una perspectiva sistémica, en la que el concepto de sinergia cobra una especial relevancia. Juntamente con el desarrollo de su teoría personológica, Millon produjo una serie de instrumentos destinados a evaluar la personalidad. Se destaca la importancia que el autor atribuye al proceso de evaluación psicológica, tan complejo como la persona misma, y la vinculación que establece entre los trastornos de personalidad (faceta disfuncional de los estilos de personalidad y los sindromes severos y clínicos con los ejes del DSM-III-R y el DSM-IV.

The postural headache syndrome associated with a decrease in the cerebrospinal fluid (CSF) pressure is generally secondary to the CSF leakage that usually occurs after diagnostic lumbar puncture. Spontaneous intracranial hypotension can not be attributed to any known cause or previous diagnostic or therapeutic intervention. The syndrome is characterized by severe headache that is relieved by lying supine. During lumbar puncture, the CSF pressure is normally low. We present two patients in whom gadolinium-enhanced magnetic resonance imaging showed widespread thickening and enhancement of the dura mater and subdural fluid collections. (Author) 13 refs.

Full Text Available O ceco móvel é uma variação anatômica embriológica do ceco e cólon ascendente resultante da descida incompleta desses segmentos do intestino grosso e da não fixação no peritônio da goteira parieto-cólica direita. A falta dessa fusão permite movimentação do ceco e/ou do cólon ascendente, facilitando a torção sobre seu eixo longitudinal ou a dobra medial do ceco sobre si, ficando encostado com sua borda medial à borda medial do cólon ascendente. Esse fato causa sintomas intermitentes de obstrução parcial do intestino ou, no caso de torção completa (volvo, de obstrução aguda com possível necrose do segmento envolvido. A anormalidade embriológica tem alta incidência (10 a 30% na população, contudo só tem sido mencionada por ocasião da torção completa, inadequadamente denominada de volvo do ceco-ascendente, em geral com necrose cecal. Dessa forma, a ocorrência não é das mais comuns e está citada entre as causas de obstrução intestinal aguda, perfazendo, nos adultos e nas crianças, menos do que 2% de todos os casos de obstruções intestinais, mas com a importância de destaque por causa do alto índice de morbi-mortalidade entre os pacientes afetados. O objetivo foi apresentar o ceco móvel como causa de dor abdominal intermitente, distensão, empachamento e cólica de origens obscuras em pessoas de aparência saudável, mas com uma longa história de distúrbios gastrintestinais funcionais, associados à constipação e/ou diarréia, portanto, com um quadro sintomatológico sobreponível ao da síndrome do cólon irritável. Além disso, propomos um marcador anatômico para a síndrome do cólon irritável, seja o subtipo com constipação predominante, seja o da diarréia predominante ou a forma em que há alternância entre constipação e diarréia e a possibilidade de alívio daqueles sintomas com a cecopexia.Functional gastrointestinal (FGI disorders are chronic or periodic conditions characterized by several symptoms whose structural and biochemical causes have not been determined. Indeed, although (FGI disorders affect millions of people of all ages, their pathophysiological mechanisms are still unclear, so that no pathological conditions have been proven to be related to this kind of illness, nor biological markers have been found to identify their sufferers. Irritable bowel syndrome (IBS has been shown to be one of the most common FGI illnesses. IBS is characterized by abdominal discomfort or pain and it has at least two of the following three features: pain relieved by bowel movements, more frequent stools with the onset of pain, and looser stools at the onset of pain - with no resultant inflammatory, metabolic or structural abnormalities. Since IBS diagnosis is fundamentally based on the description of symptoms reported by patients, it has been considered to be an exclusion diagnosis, despite the attempt to establish a connection between the origin of the illness and disorders caused by physical or sexual abuse or even by psychological disturbances. Although biochemical and hormone dosages have been performed in routine blood test for IBS, a precise biochemical marker has not been identified. Nevertheless, when the patients of this study were assessed by means of contrast intestinal radiography so as to observe topographic alterations in the cecum, it was possible to detect a mobile cecum in all of them. Would this be a coincident factor or could the mobile cecum - a widespread but misdiagnosed illness- explain the irritable bowel syndrome? The results of our study provide evidence that the majority of patients diagnosed as having IBS do not actually suffer from such illness, but rather from the mobile cecum syndrome.

Objectives: To describe magnetic resonance (MR) findings in the liver of stable patients with HELLP syndrome in the puerperium. Methods: A descriptive study was carried out from August 2005 to July 2006, involving a series of 40 postpartum patients admitted to an obstetric intensive therapy unit in IMIP (Instituto Materno Infantil Prof. Fernando Figueira) with diagnosis of HELLP syndrome (complete and partial). Complete HELLP syndrome was defined when all laboratory parameters were present and incomplete when one or more but not all laboratory findings were present. All patients had stable clinical conditions and were evaluated with magnetic resonance of the liver and the main findings were recorded. Results. Average maternal age was 26.8 {+-} 6.4 years and gestational age at delivery was 34 {+-} 26.8 weeks. The MR imaging was performed between eight and 96 hours after diagnosis of HELLP syndrome (56 {+-} 31h). The most frequent findings were ascitis in 20% (n = 8), pleural effusion in 17.5% and hepatic steatosis in 7.5%. The periportal intensity signal was normal in all cases. Cases of liver infarction and sub-capsular or parenchymatous hematoma were not observed. Conclusion: Findings of magnetic resonance imaging of the liver in stable HELLP syndrome postpartum patients were few and unspecific. Severe liver injuries such as parenchymatous or sub-capsular hematoma, entailing life risk were not found. Results do not corroborate the use of magnetic resonance as routine examination for stable patients with HELLP syndrome. (author)

Quantificazione mediante PCR dell’EBV-DNA da biopsie cutanee di pazienti con linfomi cutanei primitivi (micosi fungoide e sindrome di Sèzary

Full Text Available Mycosis fungoides (MF, the most indolent form of CTCL, originates from a clonal expansion of epidermotropic helper/memory T cells. Sezary syndrome (SS is a rare primay epidermotropic cutaneous T-cell lymphoma in leukemic. The aetiopathogenesis of MF and SS remains obscure despite several investigations. Infectious, environmental and genetic factors have been implicated as potential aetiological agents. The studies investigating the role of EBV in CTCL present conflicting results. The different sensitivities of the technical methods used in the evaluation of the presence of viral DNA or virus-related antigens make comparison of the results difficult. The aim of this study was to retrospectively evaluate the EBV-DNA load in skin biopsies from MF and SS patients by a highly sensitive (1-10 EBV-DNA copies/reaction quantitative-competitive PCR (QC-PCR developed in our lab to better asses the relationship between EBV and CTCL. Skin biopsies were obtained from 21 MF and 10 SS patients; skin biopsies from a 8 patients with inflammatory skin disease were used as controls. EBV-DNA was detected in 70% of biopsies from SS patients vs. 0% of MF patients. No control patients resulted EBV-DNA positive, as expected. In addition, in SS patients, the survival from diagnosis is lesser in EBV-positive patients vs.EBV-negative patients even if not statistically significant.We are going to investigate the presence of EBV-DNA in peripheral blood of a larger number of patients and to evaluate the pattern of viral genes expression, to better assess the aetiopathogenetical role of EB virus in this kind of neoplasies.

The radiological findings of 189 cases of Kaposi`s sarcoma occurring in patients with AIDS were studied. There was also made pathological correlations in these patients. Interstitial reticular infiltrations were frequently detected on thoracic examination showing paracardiac confluent areas. There was also lymphadenopathy, gross nodules and pleural fluid accumulation. Although there was no detection of any pathognomonic aspect, the interstitial reticular infiltration finding together with the paracardiac confluent areas and associated with gross nodules, is highly indicative to thoracic involvement by the disease.

The euthyroid sick syndrome or non-thyroid systemic illness, described by first time in 1974, is a syndrome characterized by alterations of laboratory of the thyroid tests, being values, normal serics of TSH, together with low thyroxine concentrations (T{sub 4}) and triiodothyronine (T{sub 3}) totals. The more common alteration it is the fall of the concentrations of peripheral T{sub 3} caused by the decrease of the activity 5'-deiodinase and to the deficit of the capacity of fixation of the transporter proteins. In the professional practice it should differ if the changes evidenced in the thyroid hormonal levels are induced by overthrow of the thyroid function or by non-thyroid systemic illnesses. The quantification in the laboratory it makes by means of analytical techniques appropriate and sensitive as the radioimmunoanalysis (RIA) or the immunoradiometric analysis (IRMA). These nuclear analytical techniques are based on the biochemical reaction of the antigen with the antibody where in the radioimmunoanalysis (RIA), an antigen without marking well-known as 'cold' it competes with a labelled antigen with a radioisotope I-125, well-known as 'hot', by the places of union of the antibody, and in the technique of immunoradiometric analysis (IRMA), an antibody without marked is saturated with the 'cold' antigen and the biochemical reaction is completed uniting a 'hot' antibody marked with a radioisotope I-125 this reaction is also known as 'Sandwich', in both techniques the count of the radioactivity will be in function of the concentration of the antigen without marking or 'cold'. This work was carried out in the Laboratory of Radioimmunoanalysis of the Academic Unit of Nuclear studies of the Autonomous University of Zacatecas. They were studied at 813 ambulatory patients that go to be carried out exams like part of a health control, the results that were obtained are the following 103 patients with hypothyroidism (12.66%), 40 patients with hyperthyroidism (4.92%), 500 patients euthyroid (61.5%), and with concentrations of low T{sub 3}, 170 patients (20.91%). In this study it is demonstrated that a high frequency of low T{sub 3} exists due to a thyroid dysfunction, in the population that converges to a health control, and the hypothyroidism in its subclinical forms it can be the more frequent alteration, these results will allow us to identify groups of more risk of developing a thyroid pathology after a certain time, then the diagnose it will be very opportune since we have found patient that have taken up to ten years in enjoying with an appropriate diagnose and therefore a preventive treatment.

Mechanical ventilation with a tidal volume (VT) of 6 mL/kg/predicted body weight (PBW), to maintain plateau pressure (Pplat) lower than 30 cmH2O, does not completely avoid the risk of ventilator induced lung injury (VILI). The aim of this study was to evaluate safety and feasibility of a ventilation strategy consisting of very low VT combined with extracorporeal carbon dioxide removal (ECCO2R). In fifteen patients with moderate ARDS, VT was reduced from baseline to 4 mL/kg PBW while PEEP was increased to target a plateau pressure--(Pplat) between 23 and 25 cmH2O. Low-flow ECCO2R was initiated when respiratory acidosis developed (pH 60 mmHg). Ventilation parameters (VT, respiratory rate, PEEP), respiratory compliance (CRS), driving pressure (DeltaP = VT/CRS), arterial blood gases, and ECCO2R system operational characteristics were collected during the period of ultra-protective ventilation. Patients were weaned from ECCO2R when PaO2/FiO2 was higher than 200 and could tolerate conventional ventilation settings. Complications, mortality at day 28, need for prone positioning and extracorporeal membrane oxygenation, and data on weaning from both MV and ECCO2R were also collected. During the 2 h run in phase, VT reduction from baseline (6.2 mL/kg PBW) to approximately 4 mL/kg PBW caused respiratory acidosis (pH protective mechanical ventilation strategy in patients with moderate ARDS.

Full Text Available Foi avaliada a função renal de 11 pacientes com leishmaniose cutâneo-mucosa tratados com antimonial pentavalente na dose de 40mg SbV/kg/dia aplicada de 12/12 horas, em esquema contínuo, durante trinta dias. No estudo, um paciente apresentou insuficiência renal reversível e dois desenvolveram alterações enzimáticas hepáticas e eletrocardiográficas sendo o esquema terapêutico interrompido. Nos demais pacientes observou-se efeitos nefrotóxicos tais como diminuição da taxa de filtração glomerular, diminuição da capacidade de concentração urinária, avaliada por um jejum hídrico de 16 horas e aumento na fração de excreção de sódio. No exame do sedimento urinário observou-se um aumento no número de leucócitos e cilindros. Os resultados encontrados neste estudo sugerem que o tratamento com antimonial pentavalente na dose de 40mg SbV/kg/dia foi menos tolerado em virtude de seus efeitos tóxicos, não parecendo apresentar índice de cura superior ao esquema atualmente preconizado de 20mg SbV/kg/dia.The renal function of eleven patients with mucocutaneous leishmaniasis was analyzed in a prospective study realized at the School Hospital of University of Brasília. The patients were treated with doses of 40mg/kg/day of pentavalent antimony (SbV, in a continuous scheme during thirty days. In this study three patients were excluded, one patient with reversible renal failure and two patients with hepatic and cardiac malfunctions. In the other eight patients, severe nephrotoxics effects were observed, like reduction of glomerular filtration rate, reduction of the urinary concentration capacity, evaluated by a sixteen hours hydric fasting and an increase of sodium fractional excretion. An increase in the number of leucocytes and cylinders were observed at the urinary sediment exam. Finally, the results shows that the treatment with pentavalent antimony in doses of 40mg Sb/kg/day was less tolerated on account of its renal toxics effects. This scheme seems not be superior than the currently preconized scheme of 20mg of SbV/kg/day during 30 days.

The proliferative activity of CFU-S, low in normal steady state, increases after treatment with different aggressors, i.e., radiation. This stimulation has been attributed in part to a local regulation system of stem cell proliferation, and at least in part to a humoral regulatory system. In the present work it has been investigated the role that circulating activities have in the CFU-S stimulation, by means of in vitro and in vivo incubation assays with diffusion chambers. The results show that bone marrow of mice irradiated with 5 Gy produces in vitro diffusible activities capable of stimulating the CFU-S proliferation. As well with this same dose circulating activities are also produced in vivo. In addition we have observed that these activities are only released during the periods of active hematopoietic regeneration that follow irradiation with moderate doses (1.5 and 5 Gy). In another set of experiments we saw that the stimulating activities are also detected in serum of mice irradiated with 5 Gy. These serum activities modify the proliferative state of very primitive precursors (12 d CFU-S). When the serum activities are added to long term bone marrow cultures the CFU-S are also stimulated to proliferate. Finally, we observed that the radiation-induced serum activities stimulate the proliferation of bone marrow CFU-S when injected into normal mice, suggesting that such activities are involved in the regulation of CFU-S proliferation.

Bouveret's syndrome is an uncommon disorder that consists of localized obstruction of the pyloroduodenal region caused by the passage of a gallstone through a cholecystoenteric fistula. It is most common in elderly women with a previous history of cholelithiasis. As the clinical signs are nonspecific, radiological studies are of great importance in the attempt to reach an early diagnosis, thus improving the prognosis. We present two patients with a history of cholelithiasis in whom Bouveret's syndrome was diagnosed preoperatively by different imaging techniques. (Author) 8 refs.

Hepatopulmonary syndrome is characterized by a triad consisting of liver disorder, pulmonary vascular dilatation, and hypoxaemia. No case of hepatopulmonary syndrome associated with AIDS has been reported so far. In this study, the authors report the case of a 43-year woman with AIDS and virus C cirrhosis taking prophylactic cotrimoxazole for pneumocystosis and retroviral therapy. Upon admission, the patient presented dyspnoea, cyanosis, digital clubbing, vascular spiders, and normal chest examination. Chest X-ray revealed bilateral interstitial infiltration and evidenced increased alveolar-arterial gradient and liver function impairment. Intrapulmonary shunt was evidenced by contrast-enhanced echocardiography and radionuclide perfusion scanning, thus confirming hepatopulmonary syndrome. (author)

Full Text Available El acoso psicológico en tanto modalidad de hostigamiento, no se limita exclusivamente al ámbito laboral u hogareño en tanto hecho de violencia psíquica ejercida deliberadamente hacia un sujeto en su presencia y con la intención manifiesta o no de socavar su integridad psíquica en pos de la obtención de algún beneficio en lo material o inmaterial para quien lo ejerce. Puede también comprender ámbitos como el educativo y viabilizarse por intermedio de lo virtual, facilitado por la ampliación en la utilización de las nuevas tecnologías en el aula. Surge la pregunta, desde la psicología, acerca de los límites conceptuales de la figura del hostigamiento u acoso cuando quien lo ejerce no es un sujeto plenamente conciente del alcance de sus actos ni de aquello que genera en la víctima, debido a que algunas de sus facultades mentales se encuentran socavadas como consecuencia de un cuadro psicótico presente.The psychological harassment while modality of harassment, it does not limit itself exclusively to the labour or domestic area while fact of psychic violence exercised deliberately towards a subject in his presence and with the manifest intention or not of undermining his psychic integrity in pursuit of the obtaining of any benefit in the material or immaterial thing for the one who exercises it. It can include also áreas as the educational one and viabilizarse through the virtual thing, facilitated by the extension of the utilization of the new technologies in the classroom. On the other hand the question arises, from the psychology, brings over from the limits to the figure of the harassment or I harass when the one who exercises it it´s a subject fullly conciente neither of the scope of his acts nor of that one that it generates in the victim, due to the fact that some of his mental powers are undermined to consequences of a psychotic present sindrome.

In Marfan syndrome, aneurysmatic enlargement of ascending aorta and dissection starting at the root are the most common cardiovascular complications. We present an infrequent case of a 15-year-old patient with a typical case of Marfan syndrome. CT disclosed an aorta and aortic arch of normal size with dissection originating distally with respect to the point where left subclavian artery arises. The disecction extended to descending aorta and to iliac and femoral arteries. Aortic rupture occurred in the arch, with massive hemothorax. The CT findings were confirmed at necropsy. 9 refs.

To describe immune recovery syndrome (IRS) and related radiological findings in HIV-positive patients. To alert radiologists to the ever-increasingly frequent appearance of paradoxical reactions (PR) in granulomatous diseases under antiretroviral treatment. We present a retrospective study of 9 adult HIV-positive patients who showed IRS, 6 cases of tuberculosis (TBC), 2 cases of atypical mycobacterium and a case of sarcoidosis. At the time of IRS/PR diagnosis, any suspicion of infectious activity was excluded through the use of appropriate microbiological tests. clinical and radiological characteristics of the above mentioned cases are analyze here. All patients experienced a clinical and/or radiological worsening of condition following variable periods of antiretroviral and/or anti-tuberculosis treatment, and coinciding with viral load decrease and CD4-T-lymphocyte recovery. Diagnosis of IRS/PR was clinical in five cases and radiological in four. In all but one case, antiretroviral treatment had at some time been previously administered. IRS/PR is a diagnosis of exclusion which must be included in the differential diagnosis of newly appearing lesions or worsening of already existing ones in HIV-positive patients that have recently begun antiretroviral and/or anti-tuberculosis treatment. Such should be done after excluding drug resistance, treatment non-adherence and intercurrent disease. (Author) 8 refs.

The authors report a case of a 28-year-old woman with ileocecocolic intussusception due to Peutz-Jeghers syndrome, an autosomal dominant disorder characterized by hamartomatous polyposis of the gastrointestinal tract and mucocutaneous pigmentation. This condition frequently presents complications such as intestinal obstruction due to invagination or hemorrhage. In this patient, the diagnosis of intussusception was made preoperatively. The excised material revealed three large polyps which were considered to be the cause of the intussusception. (author)

In seven of the nine affected by other sufferings it was possible to obtain results, 3 that turned out to be positive for the rearrangement among Mbcr/c-ABL and 4 normal. In all the cases, they obtained results marking the sound with radioactivity. However, they tested the marks with digoxigenin in seven of the patients, as an methodological alternative for the laboratories that lacks the requirements to work with radiation.

Ataxia-telangiectasia (AT), or Louis-Bar syndrome, is an autosomal recessive illness characterized by progressive cerebellar ataxia, oculo-cutaneous telangiectasia, immunodeficiency combined with susceptibility to sinopulmonary infections and high incidence of neoplastic development. Nijmegen breakage syndrome (NBS) is a variant of AT, is also an autosomal recessive illness that presents cerebellar ataxia, as well as combined immunodeficiency and a tendency toward tumor development. Contrary to Louis-Bar syndrome, it doesn't present telangiectasia and exhibits a characteristics phenotype (short stature, bird-like face and microcephaly). Both entities are classified as syndrome of chromosomal instability or chromosomal fragility, a group which also includes Bloom syndrome and Fanconi anemia. All of these show an increase in the frequency of neoplastic pathologies, mainly lymphoid tumors. We present three patients,two with AT and one with NBS, who developed different lymphoma types in the course of the illness. We highlight the most outstanding aspects from a clinical-radiological point of view. (Author) 17 refs.

Full Text Available We have previously reported that subarachnoid hemorrhage due to ruptured intracranial aneurysm (SH is associated with changes in the hormonal profile in the first 24 hours after the event. We proposed that the hormonal changes observed are due to the intense stress to which the patients are exposed. However, the thyroidal hormonal profile is indicative of the presence of a nonthyroidal illness syndrome (NTIS. In this paper, we examined whether the change in the thyroid hormone profile is compatible with a NTIS. Two groups of patients were included in the study: A 30 patients with SH (21 females and 9 males; 41.7±11.4 years and B a control group including 25 patients with benign diseases of the spine (BDS (lumbar disc hernia or stable spinal trauma (8 females and 17 males; 41.3±14.2 years. In a subgroup of eight patients of each group serum triiodothyronine (T3 and reverse T3 levels were measured. The blood samples were obtained between 8:00 and 9:00 AM. The following results were obtained: The SH group had smaller serum T3 and free T4 levels than the BDS group (pNós apresentamos previamente que a hemorragia subaracnoidea devido à ruptura de aneurisma intracraniano (SH está associada com alterações no perfil hormonal nas primeiras 24 horas após o evento.

Full Text Available Burnout syndrome has a high incidence among professional healthcare and social workers. This leads to deterioration in the quality of their working life and affects their health, the organization where they work and, via their clients, society itself. Given these serious effects, many studies have investigated this construct and identified groups at increased risk of the syndrome. The present work has 2 main aims: to compare burnout levels in potential risk groups among professional healthcare workers; and to compare them using standard and Bayesian statistical analysis. The sample consisted of 108 psycho-social care workers based at 2 centers run by the Granada Council in Spain. All participants, anonymously and individually, filled in a booklet that included questions on personal information and the Spanish adaptation of the Maslach Burnout Inventory (MBI. Standard and Bayesian analysis of variance were used to identify the risk factors associated with different levels of burnout. It was found that the information provided by the Bayesian procedure complemented that provided by the standard procedure.

We present the main findings observed on the high-resolution computed tomography examinations of 15 patients with acquired immunodeficiency syndrome and Pneumocystis carinii pneumonia. The high-resolution computed tomography and autopsy findings of 5 patients were also compared. The most frequently observed high-resolution computed tomography patterns were ground-glass attenuation, consolidation areas, crazy-paving pattern and cysts. Nodules and intralobular reticulation were less frequently observed. Ground-glass attenuation and consolidation areas corresponded to alveolar filling with inflammatory exudate. Thickening of the interlobular septa was due to cell infiltration and edema. One patient presented interlobular reticulation, and the pathology study revealed alveolar septa thickening due to cell infiltration and fibrosis. Nodules observed in one of the patients corresponded to a patchy intra alveolar accumulation of microorganisms and inflammatory cells forming a 'granulomatous' pattern. (author)

Hyperglycaemia has been associated with increased platelet reactivity and impaired prognosis in patients with acute coronary syndrome (ACS). Whether platelet reactivity can be reduced by lowering glucose in this setting is unknown. The aim of this study was to assess the functional impact of intensive glucose control with insulin on platelet reactivity in patients admitted with ACS and hyperglycaemia. This is a prospective, randomised trial evaluating the effects of either intensive glucose control (target glucose 80-120 mg/dl) or conventional control (target glucose 180 mg/dl or less) with insulin on platelet reactivity in patients with ACS and hyperglycaemia. The primary endpoint was platelet aggregation following stimuli with 20 μM ADP at 24 h and at hospital discharge. Aggregation following collagen, epinephrine and thrombin receptor-activated peptide, as well as P2Y₁₂ reactivity index and surface expression of glycoprotein IIb/IIIa and P-selectin were also measured. Of the 115 patients who underwent random assignment, 59 were assigned to intensive and 56 to conventional glucose control. Baseline platelet functions and inhospital management were similar in both groups. Maximal aggregation after ADP stimulation at hospital discharge was lower in the intensive group (47.9 ± 13.2% vs 59.1 ± 17.3%; p=0.002), whereas no differences were found at 24 h. Similarly all other parameters of platelet reactivity measured at hospital discharge were significantly reduced in the intensive glucose control group. In this randomised trial, early intensive glucose control with insulin in patients with ACS presenting with hyperglycaemia was found to decrease platelet reactivity.

In 2 pazienti con complicanze post-intubazione, l'esame TC mostrava una modesta raccolta fluida periesofagea con piccole bolle gassose nel contesto in un caso e nell'altro una grossolana raccolta mista di tipo ascessulae in sede periesofagea. Nei 2 pazienti con riferita ingestione di corpo estraneo, l'esame diretto cervico-toracico integrato da quello TC, evidenziava in un caso la presenza, in sede cervicale, di sottile corpo estraneo metallico (frammento di protesi dentaria) e minimo stravaso extraluminale di gastrografin, mentre nel secondo paziente, l'esame TC mostrava la pesenza di corpo estraneo (piccolo osso di pollo) a sede ipofaringea con ispessimento parietale dell'esofago ed edema dei tessuti circostanti. Nei rimanenti 3 casi con sospetta lesione spontanea dell'esofago, la TC evidenziav ain un caso la presenza di un ematoma intramurale, in un altro caso sovradistensione fluida dell'esofago con nucleo gassoso e piccola soffusione fluida periesofagea (indicativi di sindrome di Mallory-Weiss) e nel terzo caso la rottura dell'esofago (sindrome di Boerhaave). Conclusioni: Dalla nostra esperienza emerge che nella valutazione dei pazienti con sospetta lesione traumatica o spontanea dell'esofago, l'esame radiologico standard della regione cervicale e del torace puo' suggerire il sospetto di perforazione esofagea in una bassa percentuale di casi, mentre lo studio contrastografico dell'esofago per os presenta una sensibilita' piu' elevata. La TC, infine, eseguita con tecnica accurata, consente, attraverso una attenta analisi di tutti i segni suggestivi e specifici di lesione esofagea, di formulare una diagnosi corretta nella maggioranza dei casi influenzando la prognosi in modo determinante

Full Text Available Resumindo as principais contribuições que resultaram na conceituação atual da hipsarritmia, destacam os autores a noção de que não constitui ela uma entidade clínica determinada, mas uma sindrome eletroclínica especial, própria da primeira infância, e cujo diagnóstico só pode ser firmado à luz do traçado eletrencefalográfico característico. Analisam a variedade de fatôres etiológicos à maneira do que ocorre com as encefalopatias infantis em geral, chamando a atenção para a importância do fator etário, das condições traumáticas e do problema da anóxia cerebral neonatorum. Necessária ênfase é conferida ao fenômeno da maturação encefálica que explica, segundo o consenso dos autores modernos, as características peculiares da síndrome. A hipsarritmia pode instalar-se em indivíduo previamente são ou em encefalopata, tendo evolução variável, pois tanto pode evolver favoràvelmente, o que é mais raro, como modificar-se, seja no sentido da epilepsia focal ou outra forma de epilepsia, o que é mais comum, ou, então, permanecer inalterada. Essa evolução - a história natural da hipsarritmia - é apreciada especialmente sob o aspecto eletrencefalográfico, o qual pode, ou não, ser acompanhado de correspondente evolução clínica. A sintomatologia é variável, sendo de notar a grande dominância das crises de espasmos em flexão. Sendo pobre o subsídio anátomo-patológico da condição, os autores, a êsse propósito, apenas acrescentam os dados referentes à necropsia de um dos seus casos, com achados inespecíficos. O prognóstico, na maioria das vêzes mau, pode variar, especialmente após o uso do ACTH. O tratamento é difícil, freqüentemente desapontador. As melhores respostas são obtidas com o ACTH e, algumas vêzes, com os antibióticos e medicação sintomática, porém, quase sempre reaparece a sintomatologia, se suprimida a medicação que, por outro lado, nem sempre pode ser continuada.

uno studio retrospettivo di 19 donne affette da IBCO giunte all'osservazione nel nostro Istituto dal 1993 al 2002. Sono stati analizzati i dati clinico-anamnestici, mammografici, ecografici ed anatomo-patologici e, successivamente, sono stati valutati i fattori prognostici, la sopravvivenza totale (OS) e le associazioni radio-patologiche. Risultati: I reperti mammografici pi� comuni sono stati: aumento diffuso di densit� (52.63%), ispessimento trabecolare (42,1%), massa 36,84%). I reperti ecografici pi� frequenti sono stati: linfoadenopatia ascellare (68.75%), ispessimento cutaneo (43.75%) e massa (56.25%). Almeno uno dei reperti riscontrati nelle forme pi� comuni di carcinoma infiammatorio primitivo (IBC comune e clinico), in corso di mammografia (ispessimento del sottocute, ispessimento trabecolare, diffuso aumento della densit�) od ecografia (ispessimento del sottocute, aumento diffuso dell'ecogenicit�, parenchimale da edema, dilatazione dei canali linfatici) � stato riscontrato in 14 donne (74%). Nel 63,2% era presente positivit� recettoriale per gli estrogeni (ER), nel 36.8% per il progesterone. Fattori prognostici significativi sono risultati ER e Ki67. Conclusioni: Nell'IBCO il pattern radiologico dell'IBC comune e clinico viene ritrovato con frequenza inferiore; tuttavia, il radiologo deve prestare attenzione a questi segni perch� spesso solo uno di essi � presente in caso di IBCO e ci� rende possible l'orientamento verso la diagnosi corretta. Inoltre, l'assenza di segni clinici e radiologici di infiammazione non esclude la possibilit� di IBC poich� l'IBCO pu� anche manifestarsi all'imaging come massa o calcificazioni isolate. La positivit� recettoriale per estrogeni e progesterone risultando abbastanza elevata, conferma la prognosi migliore delle forme occulte rispetto a quelle clinicamente manifeste e rende opportuno un approfondimento conoscitivo delle sue caratteristiche cliniche

Rendu-Osler-Weber syndrome or hereditary hemorrhagic telangiectasia is an autosomal dominant vascular disease involving multiple systems whose main pathological change is the presence of abnormal arteriovenous communications. Most common symptoms include skin and mucosal telangiectasias, epistaxis, gastrointestinal, pulmonary and intracerebral bleeding. The key imaging finding is the presence of visceral arteriovenous malformations. The diagnosis is based on clinical criteria and can be confirmed by molecular biology techniques. Treatment includes measures for management of epistaxis, as well as surgical excision, radiotherapy and embolization of arteriovenous malformations, with emphasis on endovascular treatment. The present pictorial essay includes a report of three typical cases of this entity and a literature review. (author)

shunts, as in hepatopulmonary syndrome and a-v pulmonary fistulas, the mechanism of hypoxemia is related to the preferential circulation to basal areas of both lungs in the upright position. On the other hand, lung diseases affecting basal areas and increasing the alveolar pressure are related to the development of parenchimal pulmonary shunts with hypoxemia during postural changes, since the dead space, the functional shunt and the hypoxic vascular pulmonary constriction are affected. The autonomic neuropathy may attenuate normal sympathetic vasoconstrictor responses during postural changes, resulting in ventilation-perfusion mismatching and hypoxemia. Clinical and therapeutic aspects of this sindrome are provided.

Full Text Available The role of abnormalities of the hypophysishypothalamus- adrenal gland axis (HHA in the ongoing stress and depression is analyzed. Besides, it is evidenced that some problems, until recently considered merely endocrine-metabolic such as Cushing's syndrome (either clinical or subclinical and obesity (mainly when it is part of the metabolic syndrome may have a common etiological basis, be it a primary event, a comorbidity or a trigger in individuals with genetic susceptibility to states of maladaptative chronic stress. Some harmful effects of severe and/or ongoing hypercortisolism on some brain areas and the possibility of permanent alterations in some neuronal circuits are described. Finally, and according to some clinical evidences, the potential therapeutic role of antiglucocorticoids in the management of refractory depression is explored, as well as the role that early psychiatric intervention and antidepressant pharmacological treatment may play in some patients with the metabolic syndrome or increased cardiovascular risk.

Case histories in scientific and pseudo-scientific mass-media communication in energy/heat production from underground (geogas storage, geothermics, hydrocarbons), in the frame of Nimby Sindrome enhancement in Europe: the proposal of a new European Direct

In the frame of energy/heat production from underground, the paper considers some European case histories and the needs of a complex and motley stakeholders community, made by scientific-industry-institutions, involved in the difficult task to study and accept (or refuse) projects strongly impacting the lived territory & underground, in densely populate countries, as Italy, in terms of appropriate public communication and sound deontological behaviour. Successively, the paper recalls years of "scientific" communication within the mass-media, highlighting the positive and negative messages, in comparison to the true and objective experimental data gathered by the real scientific work, as perceived by citizens of medium scholastic culture, which not delve the geologic disciplines, but receive simply the journalistic front-end, very often as sensationalist scoop. The authors retrace case histories of heuristic-participatory communication with the citizenship about the scientific results on challenges raised by certain technologies. The objective and rational communication is often impeded by local interests and by local journalism, which prefers to create sensationalist news more than scientific truths. This path progressively tangles as a consequence of the complex and with conflicting use of underground to produce energy (heat as gas storage, geothermical, unconventional gas exploitation, mining, etc…). Even the chain of renewables meets by now serious issues, exacerbated also by the need to start mining and drilling for the smart grids materials too (metals, rare Earths, etc..). A new text for a smart and innovative European Directivity is discussed, starting from the Italian regulatory issue. The review efforts for a "paper" on both a newspaper or a blog could be more difficult than the review a scientific paper, as a consequence of the peculiar situations behind the scenes and the conflicts of interests staying in the nest in a newspaper article or in a blog comment (locally political interests, commercial interests, attention-seeking, colleagues envies, etc..). The scientific journalists are normally of low scientific and ethical level and they are often coopted by negative mechanisms (mainly political for some newspapers or TV). The paper travel over again the AAPG rule of ethics (American Association of Petroleum Geology), taking the advantage of certain concepts developed by Nomisma Energia too and of concepts coming from our work, building energy-related questionnaires, also with municipalities affected by disastrous geological adverseness (i.e., earthquakes, contamination, slides, floods), even managing infrastructures of energetic production from underground (rims, storage, geothermics, etc…). In conclusions we suggest a "scientific journalist licence" (from Italy this kind of skill is escaping) and grave procedures of "Hyppocrates adjuratory" for scientific journalists as well as for scientific community and operators involved in the sector. The case histories reported emblematic of how the road is long, meandrous but necessary.

RESULTS: Pulmonary diffuse alveolar damage showed the largest quantity of hyaline membranes (12.65% ± 3.24%, while extrapulmonary diffuse alveolar damage (9.52% ± 3.64% and idiopathic diffuse alveolar damage (7.34% ± 2.11% showed intermediate and lower amounts, respectively, with the difference being statistically significant between pulmonary and idiopathic diffuse alveolar damage (P OBJETIVO: Determinar a natureza da membrana hialina nas diferentes manifestações do dano alveolar difuso [pulmonar e extrapulmonar síndrome do desconforto respiratório] e idiopático [pneumonia intersticial aguda]. MATERIAIS E MÉTODOS: Espécimes pulmonares foram obtidos de 17 pacientes com SDRA e 9 pacientes com pneumonia intersticial aguda e separados em três diferentes grupos: (a dano alveolar difuso pulmonar (DADp (n=8 constituído por casos de pneumonia, (b dano alveolar difuso extrapulmonar (DADexp (n=9 constituído por casos de sepse e choque séptico e (c dano alveolar difuso idiopático (DADi (n=9 constituído por casos idopáticos (ou pneumonia intersticial aguda. As características das membranas hialinas do padrão histológico de dano alveolar difuso foram examinadas usando vários tipos de anticorpos. Os anticorpos usados foram surfactante apoproteina A (SP-A, anti-citokeratina 7 (CK7, citokeratina 8 (CK8, alfa actina de músculo liso (a-SMA, citokeratina AE1/AE3 (AE1/AE3 e antígeno relacionado ao fator VIII (Fator VIII. RESULTADOS: Observaram-se aumentos maiores da quantidade de membrana hialina no dano alveolar difuso pulmonar (12.65 ± 3.24%, intermediários no dano alveolar difuso extrapulmonar (9.52 ± 3.64% e baixos no dano alveolar difuso idiopático (7.34 ± 2.11% respectivamente, esta diferencia foi estatística significante entre o dano alveolar difuso pulmonar e o dano alveolar difuso idiopático (p<0.05. Não se encontrou significância estatística para a quantidade de imunomarcação de Sp-A nos grupos de dano alveolar difuso pulmonar (15.36 ± 3.12%, extrapulmonar (16.12 ± 4.58% e idiopático (13.74 ± 4.20%. Com relação ao Fator VIII, nós encontramos maiores aumentos da imunomarcação da membrana hialina no grupo dano alveolar difuso idiopático (14.12 ± 6.25% do que no dano alveolar difuso extrapulmonar (3.93 ± 2.86%, com significância estatística (p<0.001. Da mesma forma houve um aumento progressivo da imunomarcação da membrana hialina com citokeratina AE1/AE3 nos grupos de dano alveolar difuso extrapulmonar (5.42 ± 2.80% e dano alveolar difuso idiopático (0.47 ± 0.81% (p<0.001. Nenhuns dos grupos marcou para as citokeratina CK-7, CK-8 ou para a vimentina ou actina de músculo liso. CONCLUSÕES: Este estudo só mostra os componentes epitelio/endotelio (SP-A, Fator VIII e AE1/AE da barreira alvéolo/capilar que estão presentes na formação da membrana hialina nos três diferentes grupos, sugerindo que as diferenças na sua patogênese dependem da via do ferimento (direto, indireto, ou idiopático; que dependem da causa do dano alveolar difuso. As diferenças na expressão do antígeno relacionado ao Fator VIII e nas citoqueratinas AE1/AE3 no grupo DADexp versus DADi, bem como as diferenças entre HM presente no grupo DADp versus DADi sugerem a ocorrência de lesões específicas com vias diferentes (direta, indireta ou idiopática dependentes do tipo de DAD.

Full Text Available A Síndrome do piriforme é caracterizada pela compressão do nervo ciático, por se tratar de uma patologia muito frequente em atletas. O objetivo do estudo foi analisar o efeito do programa de exercícios associado à massagem em corredores fundistas. Este estudo caracterizou-se experimental. A amostra foi composta de 9 corredores que foram divididos aleatoriamente em 2 grupos A e B, com técnicas de massagens e alongamentos diferentes, realizado uma vez por semana. Foi realizada uma mensuração pré e pós-intervenção da rotação externa e interna do quadril e flexibilidade da coluna, para averiguar se ocorreu ganho na amplitude de movimento (ADM. Os resultados demonstraram que o "grupo A" obteve valores significativos (p<0,05 para o ganho de ADM em relação à média entre o "grupo B". Pode-se concluir o que os exercícios associados à massagem restabelecem a ADM e reduzem o risco de um possível acometimento a síndrome do piriforme em corredores.

Full Text Available OBJETIVO: apresentar a evolução clínica de recém-nascido portador de insuficiência respiratória grave neonatal secundária à Sindrome de Aspiração Meconial tratado por Circulação Extracorpórea por Membrana, ou, conforme o termo consagrado em língua inglesa, ECMO (Extracorporeal Membrane Oxygenation, o efeito do uso de surfactante exógeno neste caso e os custos do procedimento. MÉTODOS: Descrição de um caso de Síndrome de Aspiração Meconial, tratado na UCINE (Unidade de Cuidados Intensivos Neonatais do Instituto da Criança Prof. Pedro de Alcantara, Hospital das Clínicas da Universidade de São Paulo. RESULTADOS: O suporte extracorpóreo teve a duração de 5 dias, sem complicações clínicas ou mecânicas. Surfactante exógeno de origem porcina foi administrado no 4o dia, após o quê observamos uma melhora significativa na complacência pulmonar. O recém-nascido pôde então ser rapidamente decanulado. Os custos do tratamento foram compatíveis com a realidade nacional em relação a um recém-nascido criticamente enfermo. CONCLUSÕES: a ECMO é indicada em casos de insuficiência respiratória neonatal que não respondam a outros tratamentos existentes. Deve ser disponível em Unidades de Tratamento Intensivo (UTIs neonatais de hospitais terciários e ser empregada conforme critérios bem estabelecidos. A utilização de surfactante exógeno aparentemente antecipou a retirada da ECMO e, portanto, deve ser considerada em casos semelhantes. Os custos do tratamento justificam a organização de Equipes de ECMO nessas UTIs.OBJECTIVES: to present the clinical outcome of a newborn with severe respiratory distress secondary to meconium aspiration syndrome and treated by extracorporeal membrane oxygenation (ECMO; and to present the effect of the use of exogenous surfactant in this case and the cost of the procedure.

The epidemic curve began on May 7th, peaked on May 14th and 15th, and finalized on the 20th. The risk of illness adjusted according to age, sex and tobacco consumption was associated with the length of stay at the spa (RR=118.5, 95% C.I.: 18.7-750.2 and with swimming-pool use. Serogroup 1 L. pneumophila was detected in counts above 103 ufc/l at different points in the water therapy system and in the shower in the room of one patient. The pulsed field gel eletrophoresis analysis of one of the biological samples and environmental samples allowed genotypic confirmation. The establishment was reopened to the public after emergency treatment was carried out and confirm that after 15 days no L. pneumophila had been detected in the environmental samples.

Full Text Available INTRODUCCIÓN: la implementación de guías de manejo como apoyo al equipo médico optimiza los recursos y disminuye las complicaciones en el tratamiento de pacientes con una enfermedad determinada. Aunque las guías se conocen y se elaboran en todo el mundo, su uso es discutible, la adherencia es variable y el impacto depende de la adherencia. Su uso se ha extendido mundialmente, por lo que existen guías para diferentes enfermedades, las cuales han sido analizadas desde diversos puntos de su desarrollo, incluyendo el soporte de la evidencia existente, la adherencia dentro de los servicios de salud y, por último, el impacto de su uso sobre la morbilidad y la mortalidad en un grupo específico de la población. El Hospital Universitario San Vicente de Paúl diseñó su primera Guía de Manejo del Síndrome Hipertensivo asociado al embarazo hace 20 años y su última actualización fue en agosto de 2005. Este síndrome continúa siendo una de las principales causas de morbilidad y mortalidad maternas tanto local como nacionalmente, con indicadores superiores a los de otros países, y comparándolo con países con igual desarrollo económico, razón por la cual es pertinente contar con esta guía en las instituciones de nuestro país, como una herramienta para el cumplimiento de las metas planteadas por el Ministerio de Protección Social para la disminución de la morbilidad y mortalidad maternas. Sin embargo, esta guía no ha sido objeto de análisis. Para medir su impacto sobre los indicadores, es imprescindible conocer primero la adherencia a las recomendaciones de la guía. En un segundo paso podrá corroborarse el efecto que tienen las recomendaciones sobre la evolución de la enfermedad. OBJETIVO: evaluar la adherencia a las recomendaciones de la Guía de Manejo del Sindrome Hipertensivo Asociado a la Gestación del Hospital Universitario San Vicente de Paúl.

Full Text Available OBJETIVO:Descrever o caso clínico de paciente com Síndrome de Joubert associada a alterações renais. DESCRIÇÃO DO CASO: Paciente de dois meses de idade admitida com quadro hipotonia e hiperpneia. Ao exame físico, observaram-se, além da respiração irregular, movimentos oculares anormais e hipertensão arterial; não se evidenciaram alterações na ausculta cardíaca e pulmonar. Durante investigação clínico-laboratorial inicial, as causas cardíacas e pulmonares foram descartadas. Aventaram-se hipóteses diagnósticas de patologias neurológicas com doença renal. Os exames laboratoriais mostraram presença de alcalose respiratória, acidose metabólica e hipercalemia, com função renal normal. A ressonância magnética evidenciou alterações neurológicas compatíveis com "sinal do dente molar", quadro frequentemente associada à Sindrome de Joubert. Levando-se em consideração a associação dessa síndrome com alterações renais, a investigação nefrológica demonstrou imagens císticas em parênquima renal. COMENTÁRIOS: Patologias cardíacas e pulmonares estão frequentemente associadas a manifestações clínicas como taquipneia e distúrbios metabólicos. Entretanto, pode ser necessária uma investigação neurológica porque diversas doenças que acometem o sistema nervoso central apresentam tais alterações. A associação entre alterações renais e malformações de sistema nervoso central é frequente em diversos processos sindrômicos, justificando-se a sua investigação. A Síndrome de Joubert e as desordens a ela relacionadas caracterizam-se por aplasia do vermix cerebelar, ataxia, movimentos oculares anormais, respiração irregular e retardo do desenvolvimento neuropsicomotor. As alterações renais mais comuns são os cistos renais e a nefronoftise, que pode progredir para doença renal terminal.OBJECTIVE:To describe the case of a patient with Joubert syndrome associated with renal impairments.

Material y metodo: Se evaluaron 215 pacientes, estudiados desde enero de 1999 a agosto de 2004. Se excluyeron a pacientes portadores de material ferromagnetico o que presentaron sindrome de claustrofobia. Se utilizo un equipo Elscint de 2 tesla de campo magnetico, con bobina especifica y secuencias T1 y T2 con supresion grasa. Se evaluaron: luxaciones (reductibles y no reductibles), cambios degenerativos oseos, osteocondritis, cambios degenerativos discales, perforaciones discales, y lesiones retrodiscales. Resultados: De los 215 pacientes, se analizaron 175 pacientes que presentaron anormalidades en el estudio por IRM. Los 40 pacientes restantes fueron excluidos por presentar un estudio de (IRM) normal. De estos 175 pacientes, 146 fueron mujeres y 29 hombres. La luxacion mas comun fue la anterior y la demostracion de las lesiones articulares y la artrosis por IRM fue satisfactoria en todos los casos. Discusion: en nuestro trabajo la disfuncion de la ATM mas comun fue la luxacion anterior, concordando con otros autores. Se encontro una relacion exacta entre las luxaciones no reductibles, con cambios degenerativos oseos. Conclusion: Se demuestra que la IRM es el examen de eleccion para evaluar la ATM. El sexo femenino es el mas afectado por este tipo de patologia. La luxacion del disco es la alteracion mas frecuente encontrada en la disfuncion de la ATM, demostrando que en pacientes con osteofitosis marginales del condilo no fue posible la reduccion del disco.

Dentre os vários exames alguns testes fisiológicos ano retais avaliam a função esfincteriana e sensibilidade retal OBJETIVO: Verificar se existem diferenças entre as manometrias anais dos pacientes com constipação funcional e síndrome do intestino irritável. MÉTODO: Trata-se de estudo de 55 manometrias e testes de sensibilidade anais realizadas em pacientes atendidos no ambulatório de Fisiologia Anal do Serviço de Clínica Cirúrgica do Hospital Universitário de Taubaté com diagnóstico de constipação intestinal ou síndrome do intestino irritável no período de janeiro de 2006 a maio de 2007. Todos os pacientes possuíam colonoscopia a normal e foram incluídos nos critérios diagnósticos de Roma II para Constipação Funcional e Síndrome do Intestino Irritável. As manometrias foram realizadas com aparelho ALACER, de perfusão com 8 canais. RESULTADOS: Não foram encontradas diferenças entre as manometrias quanto às pressões de repouso, contração e evacuação, assim como nos valores de sensibilidade retal. Encontramos diferenças quanto à dor abdominal desencadeada nos pacientes com síndrome do intestino irritável no momento do volume máximo tolerável em que 69,2% destes pacientes apresentaram dor abdominal. CONCLUSÃO: Os pacientes com a síndrome do intestino irritável apresentam dor à distensão da ampola retal, que não ocorre nos pacientes constipados, na aferição do volume máximo tolerável, não houve diferença em relação aos outros dados da manometria.INTRODUCTION: In some patients the irritable bowel syndrome and the functional constipation is confuse, mainly when the predominant symptom in the irritable bowel syndrome is the constipation. Amongst some examinations the anal manometry evaluates the esfincter function and retal sensitivity. METHOD: A study of 55 anal manometry was performed at the clinic of anal physiology of the Service of Surgical Clinic of the University of Toubate Hospital in patients with diagnosis of intestinal constipation or irritable bowel syndrome from january 2006 to may 2007. All the patients presented normal colonoscopy and were included in the diagnostic criteria of Rome II for Functional Constipation and Irritable Bowel Syndrome. Manometry was performed with Alacer a perfusion device with 8 channels. RESULTS: There had not been found differences between the manometry about the pressures of rest, contraction and evacuation, as well as in the values of rectal sensitivity. We find differences in abdominal pain in patients with irritable bowel syndrome at the moment of the tolerable maximum volum where 69.2% of these patients had presented abdominal pain. CONCLUSION: Patients with the irritable bowel syndrome present pain with rectal tolerable maximum volume, that does not occur in constipated patients, in the gauging of the tolerable maximum volume, which did not have difference in relation to the other data of the manometry.

Full Text Available Resumen: La litiasis urinaria representa una patología importante en la práctica urológica y requiere de un abordaje multidisciplinario. Su incidencia es del 10%, afecta a un grupo etario extenso, con factores que pueden influir en su aumento en determinados lugares.Su diagnóstico aparece como hallazgo en controles rutinarios de salud o a través del sindrome de cólico renal, cuadro característico y de consulta frecuente en los servicios de urgencia. Su etiología no está del todo definida, siendo las hipótesis más aceptadas, las alteraciones excretoras del riñón sumada a factores ambientales y hábitos. El estudio incluye exámenes de laboratorio para descartar complicaciones como infecciones e insuficiencia renal. Las imágenes determinan el volumen de la litiasis, su ubicación y densidad, para decidir de qué manera resolver el caso, ya sea de manera espontánea o activa mediante distintos tipos de intervenciones quirúrgicas.La tomografía computarizada sin contraste se considera como el estándar de oro para el diagnóstico por imágenes de la litiasis urinaria.Los tratamientos se plantean según las distintas situaciones clínicas: manejo médico del cólico renal y terapia expulsiva para resolución espontánea del cuadro; manejo quirúrgico, cuyas técnicas más frecuentes son la nefrolitectomía o ureterolitectomía endoscópica rígida o flexible, litotripcia extracorpórea (LEC, nefrolitectomía percutánea (NLP, y finalmente el estudio etiológico de la litiasis urinaria y medidas de prevención.En niños, la incidencia de litiasis urinaria es menor que en adultos, sin embargo, las consecuencias de esta enfermedad pueden ser desastrosas. La etiología es fuertemente asociada a factores genéticos. Actualmente los tratamientos quirúrgicos son similares a los practicados en pacientes adultos. Summary: Urinary stones represent an important pathology in urological practice and requires a multidisciplinary approach. Its

Em todos os casos, o parto foi realizado em até 3 dias após a obtenção de líquido amniótico por amniocentese. O objetivo principal foi o de analisar a acurácia do teste de Clements (TC, da relação lecitina/esfingomielina (L/E, da presença de fosfatidilglicerol (PG e do perfil pulmonar (relação L/E >1,7 e PG presente para antecipar a ocorrência ou não de sindrome de desconforto respiratório neonatal (SDR. Foram calculados a sensibilidade, a especificidade e os valores preditivos positivo (VPP e negativo (VPN de todos os testes. O grupo de estudo foi composto por 48 gestações complicadas por diabetes mellitus, 41 por síndromes hipertensivas, 14 por isoimunização Rh e 18 por diversas patologias. O perfil pulmonar apresentou sensibilidade de 100% em todos os casos. O teste de Clements também não apresentou resultados falso-positivos em gestantes hipertensas, apurando-se, contudo, de 20% a 50% de falso-negativos em todos os outros testes. Os quatro testes apresentaram baixos VPP (23% no TC, 51% na relação L/E, 63% na presença de PG, 61% no perfil pulmonar e elevados VPN (92% no TC, 88% na relação L/E, 89% na presença de PG, 100% no perfil pulmonar. Este estudo demonstrou que a presença de PG e relação L/E >1,7 simultâneos no líquido amniótico comprovam a maturidade pulmonar com muito baixo risco de DR ao nascimento. Concluiu-se também que o teste de Clements deve constituir o rastreamento inicial para predizer a ausência de SDR, particularmente em gestações complicadas por síndromes hipertensivas.The objective was to evaluate the accuracy of the foam stability test, lecithin/sphingomyelin (LS ratio, presence of phosphatidylglycerol (PG and lung profile (L/S ratio > 1.7 and PG present simultaneously

Full Text Available Several side effects have been strongly associated with antiretroviral therapy in HIV patients. Among them, the lipodystrophy syndrome which presents alterations in body shape with central adipose hypertrophy and peripheral lipoatrophy, reported by patients as a visible marker identifying them as HIV patients. This manuscript presents an analysis of current literature regarding the psychosocial aspects of HIV patients with lipodystrophy associated with antiretroviral therapy. The results show that the alterations in body shape can be disturbing in terms of psychosocial well being, affecting quality of life and increasing the stigma associated with the disease, with consequent disturbances in social relations. This analysis provides a preliminary review of the psychosocial aspects of lipodystrophy and further studies are needed for a better understanding of this complex syndrome, which could provide new information to be used in nursing care for HIV patients affected by this problem.Varios efectos secundarios han sido fuertemente asociados con la terapia antiretroviral en pacientes con HIV. Entre ellos, el síndrome de la lipodistrofia se presenta con alteraciones en la forma del cuerpo con hipertrofia adiposa central y lipoatrofia periférica, las cuales son reportadas por pacientes como marcas visibles que los identifica como pacientes con VIH. En este manuscrito, presentamos un análisis de literatura actual con respecto a los aspectos psicosociales de pacientes con VIH presentándose con lipodistrofia asociado con la terapia antiretroviral. Los resultados demuestran que las alteraciones de la forma del cuerpo pueden ser inquietantes en lo que se refiere al bienestar psicosocial, afectando la calidad de vida y aumentando el estigma asociado con la enfermedad, con las consiguientes dificultades en las relaciones sociales. Este análisis provee un repaso preliminar de los aspectos psicosociales de la lipodistrofia; sin embargo, otros estudios son necesarios para entender mejor este complejo síndrome, proveyendo nueva información para ser utilizada en el cuidado de enfermería para pacientes con VIH que están afectados por este problema.Diversos efeitos colaterais têm sido associados à terapia anti-retroviral em portadores da infecção pelo HIV, dentre esses, a síndrome da lipodistrofia apresentando hiperlipidemia e alterações na forma do corpo, com hipertrofia adiposa central e lipoatrofia periférica, relatada pelos pacientes como um visível marcador para a identificação de portadores da infecção pelo HIV. Este estudo consiste em análise da produção científica sobre aspectos psicossociais em portadores da infecção pelo HIV que apresentam lipodistrofia associada à utilização da terapia anti-retroviral. Os resultados mostram que alterações corporais podem ser suficientemente perturbadoras para o bem-estar psicossocial, afetando a qualidade de vida e aumentando o estigma da doença, ocasionando perturbações nas relações sociais. Esta revisão possibilita uma análise preliminar dos aspectos psicossocias da lipodistrofia; entretanto, outros estudos são necessários para o melhor entendimento desta complexa síndrome, trazendo novas informações a serem utilizadas no cuidado de enfermagem a portadores da infecção pelo HIV afetados por este problema.

extendedora Cortland modificada en dilucion 1:50, y se utilizaron para probar el efecto de nueve dosis de radiacion ultravioleta (0.2-1.0 J cm{sup -}2 ) sobre la duracion de la motilidad en segundos, el indice de motilidad del esperma, y los porcentajes de superviviencia de embriones obtenidos de la fertilizacion de huevos provenientes de cinco hembras de la misma especie. Los tiempos de motilidad del esperma en las muestras irradiadas con 0.2-0.9 J cm{sup -}2 resultaron estadisticamente no diferentes de los controles, mientras que las muestras irradiadas con 1.0 J cm{sup -}2 fueron significativamente menores. El indice de motilidad (IM), por otra parte, permitio la diferenciacion estadistica de cuatro grupos en cuanto a su respuesta a diferentes dosis de radiacion. El primer grupo se caracterizo por valores altos del IM, e incluyo a los controles y a las muestras irradiadas con 0.2-0.3 J cm{sup -}2; el segundo agrupo a las irradiaciones de 0.4 a 0.7 J cm{sup -}2, en las cuales se observo un descenso del IM; en el tercer grupo (0.8-0.9 J cm{sup -}2 ) el IM aumento nuevamente; y en el ultimo (1.0 J cm{sup -}2) se observo el menor IM. En cuanto a los porcentajes de supervivencia, se observo una curva descendente con valores altos de supervivencia en los controles y en las muestras irradiadas con 0.2 J cm{sup -}2, con un descenso en los tratamientos de 0.3 a 0.4 J cm{sup -}2, y una recuperacion significativa a partir del tratamiento de 0.5 y hasta 0.8 J cm{sup -}2, observandose nuevamente un decremento en la supervivencia de los tratamientos de 0.9 a 1.0 J cm{sup -}2 . Ambos resultados, IM y supervivencia, indican que la dosis optima para la produccion de organismos haploides se encuentra cercana a 0.7 J cm{sup -}2. En el tratamiento de 0.7 J cm{sup -}2 se observaron larvas con las caracteristicas tipicas del sindrome haploide, indicando nuevamente que esta puede ser la dosis mas adecuada para producir organismos ginogeneticos.

Lorsqu'une dose d'environ 1 {mu}c de thymidine tritiee par gramme de poids du corps est injectee aux souris, on peut suivre pendant un mois les transformations metaboliques de la thymidine incorporee a l'acide deoxyribonucleique (ADN) des divers tissus. (author) [Spanish] Ya se han presentado informes acerca de los procedimientos aplicados para la determinacion cuantitativa del tritio en tejidos animales y fracciones aisladas de los mismos. Sin embargo, en los trabajos respectivos se han utilizado siempre, para el recuento de la muestra, espectrometros de coincidencia de centelleador liquido. En cambio, en el presente trabajo las mediciones se han efectuado con un contador de centelleador liquido equipado con un fototubo unico. Se investigo principalmente la disolucion directa de tejido animal en la hiamina 10-KH y el recuento del tejido liofilizado en suspension en geles de centelleo. Es posible disolver directamente en hiamina tejidos diferentes tales como el hepatico, el intestinal, el sanguineo y el cutaneo, y medirlos con un rendimiento de 10 a 15%. El autor examina la tecnica aplicada para la correccion por extincion, asi como ciertos fenomenos de fosforescencia que afectan la determinacion en el sistema de recuento de fototubo unico. Parece que el metodo ofrece una sensibilidad suficiente para muchas aplicaciones, aunque un poco menor que la del dispositivo de recuento por coincidencias.

Full text. In order to evaluate the profile of the sex steroids gonadotropin and prolactin in polycystic ovarian syndrome (POS), 24 patients with POS were studied and compared with 20 normal women during the early follicular phase of the menstrual cycle. Radioimmunoassay techniques for androstenedione (A) and estrone (E{sub 1}) were standardized for the purpose of the study. Androstenedione and estrone were extracted from plasma with ethyl ether. The assays were maintained in equilibrium and the labelled hormone-antibody complex was then separated from the free hormone using dextran charcoal. The sensitivity of the method was 6.8 pg/tube for A and 3.7 pg/tube for E{sub 1}. Nonspecific binding ws 3.4 for A and 3.3 for E{sub 1}. The interessay error at the D50 level was 15.6 for A and 8.6 for E{sub 1}. Patients with POS had significantly higher basal levels of LH, A, T E{sub 1} and PRL and similar FSH and DHEA-S levels when compared with normal women. The LH/FSH ratio was significantly elevated and the A/T ratio was significantly decreased. The A/E{sub 1} and T/E{sub 2} ratios were elevated and the E{sub 1}/E{sub 2} was decreased, although the differences were not statistically significant. A positive correlation between A and E{sub 1} was observed in patients with POS. In view of the above data, it was concluded that: the quality control parameters of the radioimmunoassay for A and E{sub 1} standardized in the present study are considered satisfactory, and the assay could be used for diagnosis and research; the patients with POS have a different sex steroid and gonadotropin profile when compared normal women during the early follicular phase of the menstrual cycle

Les auteurs ont egalement mesure la vitesse de conversion du styrene en homopolymere dans les peluches en suspension. Ils ont fait des examens microscopiques des pellicules greffees afin de connaitre la quantite d'homopolymere absorbe. Les resultats obtenus montrent que l'augmentation de poids dans les echantillons de pellicules est due en grande partie a l'homopolymere absorbe. Pour les experiences faites sur les peluches, dans lesquelles l'augmentation de poids est imputable en grande partie au copolymere greffe, cette augmentation est a peu pres proportionnelle a la dose et la vitesse de reaction est presque proportionnelle a la racine carree du debit de dose des rayons gamma. Du fait d'une energie d'activation faible pour la vitesse de reaction, on ne peut pas agir sur la vitesse de diffusion dans les peluches et dans des pellicules minces si les debits de dose sont inferieurs a 10{sup 5} r/h. La vitesse de formation de l'homopolymere dans les experiences sur peluches faites a 18{sup o}C et a 7,2 x 10{sup 4} r/h est la meme que dans l a polymerisation du styrene pur. L'energie d'activation, 3,5 kcal/mole, represente a peu pres la moitie de la valeur enregistree pour le monomere pur.

Los autores demuestran que los modelos utilizados por otros investigadores en la interpretacion de los datos sobre el incremento de peso con miras a determinar las constantes de velocidad carecen de validez en este caso.

Patología Quirúrgica Neonatal de Alto Riesgo. Del Académico Hernando Forero Caballero

la medicina ha sido el control casi total de la mortalidad materna e infantil durante el embarazo y el parto, pero esto no ha hecho que las malformaciones fetales y neonatales hayan disminuido, aunque se tiene hoy en día la esperanza fundada en la genética que pueda conducir a la prevención de tan doloroso cuadro.

La humanidad, en su extrema dureza, se ha ensañado siempre con la niñez, ejemplo de ello son las actitudes brutales y condenables de pueblos enteros que arrojan a la muerte a los recién nacidos del sexo femenino, o a los que presentan sindrome de Down, o malformaciones congénitas, u obligan a los que sobreviven a los trabajos mas rudos o, mas tarde a la prostitución, al analfabetismo y a la delincuencia, como pasa para nuestra vergüenza en la actualidad en nuestra tierra.

Pero en medio de este angustioso estado de cosas y como contrapeso a tanto dolor, surgen personas como el doctor Hernando Forero Caballero que, como el mismo lo dice “en su soledad de Profesor emérito retirado”, crean obras como las que hoy oficialmente ha presentado ante esta benemérita Academia.

El libro del Académico Forero tiende, en el campo científico, a compendiar en un volumen de naturaleza netamente didáctica, el enfoque con el que el cirujano pediatra neonatólogo debe atender el producto intrauterino, o al recién nacido que presente esas terribles deficiencias, que tanto dolor y angustia producen en sus progenitores y familiares, o para recuperar para la sociedad a los miles de niños condenados antes a la muerte, o al sufrimiento y a la burla durante su triste existencia...

total of 38 centering. Eight patients underwent the PNE procedure on both the S3 foramina. The sacral foramen was centred at the first attempt in 36 out of 38 cases. Two cases required several attempts to centre correctly the foramen. In 4 patients out of 30 a second electrode was implanted. In one patient who had a non consolidated sacral fracture, CT guidance enabled insertion of the electrode inside the only practicable foramen, a manoeuvre that would have been impossible with fluoroscopic guidance. Only once was repositioned after a CT control. During the whole trial period we had a positive response to the PNE test in 18 out of 30 patients (60%), a partial response in 4 out of 30 patients and a negative response in the remaining 8 patients. None of the patients who underwent the PNE test had infectious complications and the procedure was well tolerated by all. The procedure lasted about 45 minutes. Conclusions: The PNE test under Ct guidance proved to be more efficient compared with the traditional technique as the direct view of the electrode position helped to define with greater reliability the patients who were non-responsive to sacral stimulation. Moreover, this method was particularly efficient in patients with sacral anomalies where the traditional guide might fail. The operators' reduced exposure to radiation is an advantage to be taken into consideration. Finally, the usage of mobile CT apparatus in an operating theatre can improve the technique for permanent implantations.

que no es en cadena y que pasa por los radicales (C{sub 6}H{sub 5}){sub 2}C-OH and (CH{sub 3}){sub 2}COH. La reaccion se retarda y se inhibe mediante mercaptanos y disulfuros, que reconvierten los radicales en los productos iniciales por medio de reacciones rapidas de transferencia de hidrogeno y que recobran sus estados de valencia primitivos; en ese proceso, cada molecula de compuesto sulfurado anula los efectos qufmicos de numerosos cuantos: (C{sub 6}H{sub 5}){sub 2}C-OH + AS' -> (C{sub 6}H{sub 5}){sub 2}C = O + ASH; (CH{sub 3}){sub 2}C-OH + ASH -> (CH{sub 3}){sub 2}C = 0 + AS'. La prueba de este mecanismo se halla en los siguientes procesos que se observan durante la inhibicion: equili- bratniento del mecaptano o disulfuro inicialmente presentes, racemizacion del alcohol opticamente activo e intercambio de deuterio. Se observa una inhibicion analoga cuando solo se forma un radical intermedio, como en los sistemas benzofenona-benzhidrol y acetofenona-alcohol-{alpha}-metilbencflico. La accion inhibidora de los compuestos sulfurados que obedece al mismo mecanismo, se observa en la transformacion de la benzofenona en benzopinacol, inducida por los rayos gamma del {sup 60}Co; si bien el naftaleno interrumpe la reaccion fotoquimica, no ejerce efecto protector alguno sobre la benzofenona en ese sistema. Asi, pues, la proteccion de los solutos contra las dafios radioinducidos mediante compuestos de azufre se debe a reacciones de transferencia de atomos de hidrogeno. Los compuestos sulfurados tambien inhiben en virtud de reacciones de transferencia de atomos de hidrogeno, la fotorreduccion de la benzofenona en eteres. Se observa en este sistema (a diferencia de los sistemas cetona- alcohol) un mecanismo por el cual los compuestos sulfurados pueden consumirse de manera irreversible. Esto conduce a un periodo de induccion en lugar de un retardo permanente; cada molecula de compuesto de azufre anula los efectos de unos 15 cuantos. (author) [Russian] Reakcii so svobodnymi

- 90 con una actividad normalizada de 1 a 1,5 mc/cm (longitud radiactiva). La actividad se controla simultaneamente por recuento 4 {pi} por densimetria mediante pelicula. La dosis de referencia se calcula siempre de la misma manera, a 2 mm de la pared del tubo, suponiendo que la intensidad de dosis es del orden de 10 rad/min para una actividad de 1 mc/cm. Aplicaciones terapeuticas: La actividad radiobiologica de las agujas de itrio- 90 no esta bien estudiada aun. La dosis disminuye rapidamente a partir de 3 mm de la pared de la aguja, lo que dificulta la irradiacion homogenea de los tejidos tratados. En principio, las agujas se podrian colocar a 5 o 6 mm una de otra, pero esto requiere un dispositivo de implantacion muy dificil de manejar; un error de 1 o 2 mm podria producir excesivos puntos calientes o frios. Por tal motivo, en una primera etapa, los autores utilizaron las agujas en tumores angiomatosos benignos sin tratar de irradiar homogeneamente el tejido, sino solamente de crear zonas de esclerosis, concentricas a las agujas, separadas por zonas de tejido poco o nada irradiadas. De esta manera, esperan lograr en algunos angiomas tuberosos un efecto esclerogeno suficiente con la ventaja de que los enfermos reciben una dosis integral muy reducida. La ausencia de difusion en los tejidos sanos tiene particular interes para los angiomas situados cerca de tejidos radiosensibles (globo ocular, glandula mamaria) o proximos a las gonadas. Al parecer, los resultados obtenidos en los primeros casos tratados son satisfactorios. En una segunda etapa, los autores esperan poder utilizar estas agujas en tumores cutaneos malignos situados tambien en la vecindad de tejidos sanos radiosensibles (por ejemplo, cancer de los parpados) [Russian] V naotojashheee vremja v sotrudnichestve s jaderkym centrom Sakle tehnicheskij otdel vnutritkanevoj radioterapii instituta Gustava Russi izuchaet nekotorye vidy terapevticheskogo primenenija vnutritkanevoj betaterapii s pomoshh'ju ittrija-90
