Anatomía del cuerpo calloso en ratas sometidas a estrés prenatal crónico / Anatomy of corpus callosum in rats submitted to chronic prenatal stress

RESUMEN: El cuerpo calloso (CC), es la mayor comisura de sustancia blanca del encéfalo de los mamíferos placentados, constituida por numerosos haces de fibras transversales que conectan áreas corticales de ambos hemisferios cerebrales. Por otro lado, el estrés se define como una respuesta general del organismo ante demandas externas o internas, inicialmente amenazantes, que consiste en movilizar recursos fisiológicos y psicológicos para poderlas afrontar. Dada la importancia del cuerpo calloso en las conexiones cortico-corticales, el objetivo del presente estudio, fue evaluar el efecto en ratas, de un estrés prenatal crónico por inmovilización, sobre la anatomía macroscópica del CC. Se utilizaron seis ratas preñadas de la cepa Wistar de 250 g, de las cuales tres fueron sometidas, a partir del octavo día postconcepción, a una restricción de movimiento por diez días (2h/día). Posteriormente, las madres prosiguieron su gestación, parto y lactancia. Al nacimiento, las camadas fueron ajustadas a seis crías machos por madre (n=36), destetadas a los 21 días y sacrificadas a los 45-52 días de edad. Los encéfalos fueron seccionados a través de la cisura interhemisférica y ambos hemisferios fotografiados por su cara medial. Las imágenes fueron digitalizadas y analizadas mediante el programa Scion Image®, para la medición del área total, parciales (tercio anterior, medio, posterior y quinto posterior) y perímetro callosal. Es así como, el estrés prenatal por inmovilización, afectó significativamente (p<0,01), la morfología macroscópica del cuerpo calloso. Evidenciándose una disminución del área total, áreas parciales y perímetro callosal, en los animales sometidos a restricción prenatal. Estableciendo una relación directa entre número de axones y área callosal e inversa entre diámetro y densidad axonal; lo observado podría tener incidencia en la transferencia interhemisférica.

SUMMARY: The Corpus Callosum (CC) is the largest white matter commissure in the brain of placental mammals, consisting of numerous transverse fiber bundles that connect cortical areas of both cerebral hemispheres. On the other hand, stress is defined as a general response of the organism to external or internal demands, initially threatening, which consists of mobilizing physiological and psychological resources to be able to face them. Given the importance of CC in cortico-cortical connections, the aim of the present study, was to evaluate the effect of chronic pre-natal immobilization stress on the macroscopic anatomy of CC in rats. Six 250g pregnant rats of the Wistar strain were used, of which three were subjected, starting on the eighth post-conception day, to movement restriction for ten days (2h/day). Subsequently, the mothers continued their gestation, delivery and lactation. At birth, litters were adjusted to six male offspring per mother (n=36), which were weaned at 21 days and slaughtered at 45-52 days of age. The brains were fixed, and later sectioned through the interhemispheric fissure and both hemispheres photographed by their medial aspect. The images were digitized and analyzed using the Scion Image® program, for the measurement of the total area, partial area (ante- rior, middle and posterior thirds, as well as posterior fifth) and callosal perimeter. Thus, prenatal stress due to immobilization significantly affected (p<0.01), the macroscopic morphology of the CC. Evidence shows a decrease in the total area, partial areas and callosal perimeter in the animals subjected to prenatal restraint, as compared to normal animals. Establishing a direct relationship between number of axons and callosal area and an inverse relationship between diameter and axonal density, what was observed may have an impact on interhemispheric transfer.

Good tolerance and benefits should make early exercises a routine in patients with acute brain injury / Boa tolerância e benefícios de exercícios precoces devem fazer parte da rotina em pacientes com lesão cerebral aguda

Abstract Introduction: The negative impact of prolonged immobilization results a physical decline during hospitalization in patients with acute brain injury. Objective: To investigate the benefits of early exercises on the mobility of patients with acute brain injury assisted at an Intensive Care Unit (ICU). Methods: This is a prospective, single-blind, controlled clinical trial. A total of 303 patients were assessed. Due to eligibility criteria, exercise protocol was applied in 58 participants, 32 with brain injury caused by traumatic event and 26 with brain injury caused by cerebrovascular event. Exercise began 24 hours after patients' admission at the ICU. Participants were submitted to passive and active mobilization protocols, performed according to level of sedation, consciousness and collaboration. Statistical analysis was conducted with repeated measures analysis of variance. Significance was set at 5%. Results: The group of patients with traumatic brain injuries was younger (p = 0.001) and with more men (p = 0.025) than the group of patients with clinical events. Most exercise sessions were performed in sedated patients. By the end of the protocol, participants with traumatic and clinical brain injury were able to do sitting and standing exercises. Both groups were similar on ICU discharge (p = 0.290). The clinical group presented better improvement on level of consciousness than the traumatic group (p = 0.005). Conclusion: Participants with an acute brain injury presented at the time of discharge from the ICU good mobility and improvement in the level of consciousness.

Artrogripose Múltipla Congênita: Relato de dois casos / Arthrogryposis Multiplex Congenita: Report of two cases

RESUMO: A Artrogripose Múltipla Congênita (AMC) é uma síndrome rara, que representa um grupo de condições congênitas caracterizado por contraturas articulares em duas ou mais articulações, não progressivas, geralmente simétricas, de etiologia desconhecida e que pode estar associada a outras malformações, como viscerais e neurológicas. Apresenta-mos dois casos isolados com achados característicos de AMC, atendidos em ambulatório de pediatria de alto risco de uma cidade do Oeste do Paraná. Caso 1: lactente, sexo feminino, 14 dias de vida, com redução dos movimentos fetais referidos pela mãe, apresentando malformações envolvendo somente os membros, visualizadas logo após o nasci-mento. Caso 2: lactente, sexo masculino, quatro meses de vida, com diagnóstico de hipocinesia fetal ao ultrassom obstétrico de 23 semanas, ao nascimento apresenta contraturas dos membros e disfunção do sistema nervoso cen-tral. O diagnóstico da artrogripose é complexo e essencialmente clínico, sendo necessária uma anamnese meticulosa, contemplando uma avaliação da gestação, via de parto, história familiar e um exame físico minucioso, classificando quais os tipos de contraturas, membros envolvidos, presença de musculatura alterada e de alterações neurológicas, a fim de diferenciar a AMC das outras síndromes que também cursam com contraturas articulares. O seguimento e tratamento dos lactentes com artrogripose devem ocorrer em acompanhamento multidisciplinar devido às variadas manifestações que a doença pode apresentar e à característica de recidiva ao longo dos anos. (AU)

ABSTRACTArthrogryposis Multiple Congenita (AMC) is a rare syndrome that represents a group of congenital conditions character-ized by joint contractures in two or more joints, non-progressive, usually symmetrical, of unknown etiology and which may be associated with other malformations, such as visceral and neurological. We present two isolated cases with characteristic features of AMC, seen in a high-risk pediatrics outpatient clinic in a city in western Paraná. Case 1: infant, female, 14 days old, with reduced fetal movements reported by the mother, presenting malformations involving only the limbs, seen immediately after birth. Case 2: infant, male, four months old, diagnosed with fetal hypokinesia on 23-week obstetric ultrasound, at birth, presents limb contractures and central nervous system dysfunction. The diagnosis of ar-throgryposis is complex and essentially clinical, requiring a meticulous anamnesis, including an assessment of pregnan-cy, delivery, family history and a thorough physical examination, classifying what types of contractures, involved limbs, presence of altered musculature and neurological changes to differentiate AMC from other syndromes that also have joint contractures. The aftercare and treatment of infants with arthrogryposis must occur in multidisciplinary follow-up due to the varied manifestations that the disease may present and the characteristic of recurrence over the years.

Severe Osteoarthritis of the Elbow after a Non- Displaced Radial Head Fracture: Case Report / Osteoartrite global do cotovelo após uma fratura não deslocada da cabeça radial: Relato de caso

Abstract Fractures of the radial head account for over 50% of all fractures of the forearm. Broberg and Morrey (modification of the Mason classification) classify them in four types. Type 1 fractures are non-displaced or minimally displaced, considered stable and without mechanical joint blockage. In this type of fracture, a non-operative management with a short period of immobilization leads to a good clinical result without adverse outcomes. Clinically relevant associated lesions are not common. Because of this, arthritis of the radiocapitellar and ulnohumeral joint after the non-displaced radial head fracture is uncommon. This case report presents a young patient diagnosed with isolated non-displaced radial head fracture, that evolved 8 months later, to global arthritis of the elbow.

Resumo As fraturas da cabeça radial representam mais de 50% de todas as fraturas do antebraço. Broberg e Morrey (modificação da classificação de Mason) as classificam em quatro tipos. As fraturas do tipo 1 são aquelas não deslocadas ou minimamente deslocadas, consideradas estáveis e sem bloqueio mecânico das articulações. Nesse tipo de fratura, um manejo não operatório com um curto período de imobilização permite bom resultado clínico sem desfechos adversos. Lesões associadas clinicamente relevantes não são comuns. Por esse motivo, a artrite da articulação radiocapitelar e ulnoumeral após a fratura da cabeça do rádio não deslocada é incomum. Este relato de caso apresenta um paciente jovem com diagnóstico de fratura isolada da cabeça radial não deslocada que evoluiu, 8 meses depois, para artrite global do cotovelo.

Prevalência de cuidados paliativos em pacientes com síndrome de imobilidade em um serviço de atenção domiciliar / Prevalence of palliative care in patients with immobility syndrome in a home care attention service

Introdução: a síndrome de imobilidade (SI) é definida por critérios clínicos específicos, a saber, presença dos dois critérios maiores, declínio cognitivo e múltiplas contraturas e pelo menos dois dos menores, disfagia, afasia, lesão por pressão e dupla incontinência, tendo indicação de cuidados paliativos desde o momento de sua identificação. Objetivo: determinar a prevalência da SI em pacientes em atendimento domiciliar e verificar a inclusão destes em cuidados paliativos. Métodos: estudo documental, descritivo-exploratório e retrospectivo, coletados do prontuário dos pacientes do Serviço de Atendimento Domiciliar de Curitiba, no período de 1 a 31 de julho de 2018, totalizando 566 pacientes. Critérios de inclusão: idade igual ou superior a 18 anos, estar em atendimento domiciliar, apresentar critérios para SI. Critérios de exclusão: dados incompletos que impeçam a caracterização da SI. Foi utilizado o teste de associação de qui-quadrado e o teste da ANOVA. Considerou-se o p ≤ 0,05 com significância estatística. Resultados: 56 (9,9%) apresentaram critérios para SI. A ocorrência da SI no sexo feminino foi de 13,1% e no masculino 6,1%, com significância estatística (p=0,0218). A média de idade de 72,43. Quanto aos critérios menores, n=56 (100%) tinham dupla incontinência, n=48 (83,9%) disfagia, n=41 (73,2%) afasia e n=31 (55,4%) lesões por pressão. Dos pacientes com SI, 44,46% estavam em cuidados paliativos. Conclusão: a SI foi associada ao sexo feminino, a média de idade foi 72,43 anos. A prevalência foi de 9,9%, dos quais somente 44,46% estavam em cuidados paliativos, o que nos aponta que o atendimento domiciliar não está ofertando aos seus pacientes o melhor atendimento possível. Palavras-chave: Imobilização. Cuidados paliativos. Serviços de assistência domiciliar.(AU)

Introduction: the immobility syndrome (IS) is defined by specific clinical criteria, namely, presence of the two major criteria, cognitive decline and multiple contractures and at least two of the smallest, dysphagia, aphasia, pressure injury and double incontinence and indicates palliative care from the moment of its identification. Objective: to determine the prevalence of IS in patients in home care and to verify their inclusion in palliative care. Methods: this is a documentary, descriptiveexploratory and retrospective study, collected from patients' records of the Home Care Service of Curitiba, from 1 to 31 July 2018, totaling 566 patients. Inclusion criteria: age equal to or greater than 18 years, being in home care, presenting criteria for IS. Exclusion criteria: incomplete data that prevent the characterization of the IS. The chi-square association test and the ANOVA test were used. The p ≤ 0.05 was considered statistically significant. Results: n=56 (9.9%) presented criteria for IS. The occurrence of IS in the female sex was 13.1% and in the male, 6.1%, with statistical significance (p=0.0218). The mean age was 72.43. Regarding the minor criteria n=56 (100%) had double incontinence, n=48 (83.9%) dysphagia, n=41 (73.2%) aphasia, and n=31 (55.4%) pressure injuries. Of the patients with IS 44.46% were in palliative care. Conclusion: IS was associated with females, mean age was 72.43 years. The prevalence was 9.9%, of which only 44.46% were in palliative care, which indicates that home care is not offering its patients the best care possible. Keywords: Immobilization. Palliative care.

Triple open dislocation in the index finger of the hand without a high-energy trauma / Triple luxación abierta del segundo dedo de la mano tras traumatismo de baja energía

A simultaneous double dislocation (both proximal [PIP] and distal [DIP] interphalangeal joints) of a triphalangeal finger is a rare entity. The most common hand affected is the right hand. In the case of a closed triple dislocation (metacarpophalangeal [MCP], PIP and DIP joints); there are only two cases in the literature revised. In this case, we report an open triple dislocation in the index finger of the left-hand of a 54-year-old man treated by closed reduction and 3 weeks of immobilization followed by active mobilization with satisfactory results.

La luxación simultánea de las articulaciones interfalángicas proximal (IFP) y distal (IFD) de un dedo de tres articulaciones es una rara entidad. La mano que es afectada con más frecuencia es la derecha. Con relación a una triple luxación cerrada (articulación metacarpofalángica [MCF], IFP e IFD), sólo hay descritos dos casos en la literatura revisada. En este caso, describimos una triple luxación abierta del segundo dedo de la mano en un varón de 54 años de edad tratada mediante reducción cerrada,e inmovilización durante 3 semanas seguida de movilización activa supervisada, con resultado final satisfactorio.

Updates on the Diagnosis and Treatment of Restless Legs Syndrome / 신경정신의학

Restless legs syndrome (RLS) is a neurological sleep disorder characterized by an urge to move the legs or arms and is associated with discomfort and paresthesia in the legs. RLS is diagnosed based on the clinical symptoms, and polysomnography is performed to quantify the periodic limb movements during sleep or in patients who undergo the suggested immobilization test. Determining the cause of RLS is important for accurately diagnosing and evaluating this condition. The treatment of RLS varies according to the etiology, severity, and frequency of the patients' symptoms. Accurate identification and treatment of the cause of RLS are important in patients with secondary RLS. Iron supplementation could be useful in patients with uremia, iron deficiency, and for RLS during pregnancy. Dopamine agonists have been used as the first-line treatment for primary RLS. On the other hand, augmentation is a known adverse effect associated with the long-term use of dopamine agonists. Therefore, recent treatment guidelines recommend the administration of anticonvulsants, such as pregabalin and gabapentin, to treat RLS. Iron, opioids, or benzodiazepines may be useful in patients refractory to anticonvulsants or dopamine agonists. RLS is a chronic condition. Therefore, it is essential to establish a long-term treatment plan, considering both the efficacy and adverse effects of therapeutic agents used in patients.

Immobility is a syndromic disease that significantly deteriorates the quality of life of elderly, since the immobilized elderly person is a high-risk patient for complications.

Luxación de la articulación temporomandibular: apropósito de un caso y su diagnóstico diferencial / Luxation of the temporomandibular joint: about a case report and its differential diagnosis

Resumen La luxación temporomandibular es infrecuente, pero genera gran repercusión en el esqueleto facial. En ocasiones el cuadro clínico inicial es inespecífico y puede confundirse con otras patologías si no se tiene un adecuado conocimiento del tema, o se realiza una anamnesis incorrecta. Este artículo presenta el caso de una paciente que consultó al servicio de urgencias por disartria y desviación de la comisura labial hacia la izquierda, asociado a dolor severo y parestesia en hemicara derecha. No obstante, al ingreso la paciente refirió síntomas ambiguos, que para el médico evaluador sugirieron una causa neurológica. Durante la observación se solicitó valoración por servicio de cirugía plástica, se logró orientación de la anamnesis y examen físico, obteniendo una impresión diagnóstica de luxación de articulación temporomandibular derecha, confirmada por imagenología, y por ende un tratamiento oportuno con reducción e inmovilización en el servicio de urgencias. MÉD.UIS.2019;32(3):49-54

Abstract The temporomandibular joint dislocation is uncommon, but it causes a great repercussion on the facial skeleton. Occasionally, the initial symptoms can be unspecific and confuse with other pathologies if there are not an adequate knowledge of the topic and the anamnesis is incorrect. This article presents a clinical case of a patient with dysarthria and left deviation of the labial commissure, associated with severe pain and paresthesia in the right side of the face. Nevertheless, the patient initially referred ambiguous symptoms, suggesting a neurological cause. During observation in the emergency room, plastic surgery service valorated the patient, with subsequent orientation of the anamnesis and physical examination, achieving a satisfactory management of the acute dislocation.

An efficient method of Yarrowia lipolytica immobilization using oil- and emulsion-modified bacterial cellulose carriers

Background: Yarrowia lipolytica is a nonconventional, dimorphic yeast with multiple biotechnological applications. Considering the size of Y. lipolytica cells and a plethora of its morphological forms (spherical cells or hyphae and pseudohyphae), it is highly difficult to select a suitable carrier for this useful microorganism. Bacterial cellulose (BC) is currently considered one of the most promising immobilization carriers. In the current study, the usefulness of oil- and emulsion-modified BCs as a carrier for Y. lipolytica immobilization was investigated. Static and agitated cultures were conducted in media supplemented with oil or emulsion to improve carrier porosity. Results: It was found that the application of oil- and emulsion-modified BCs correlated with significantly higher efficiency of Y. lipolytica immobilization and hence higher yield than the yield achieved with an unmodified carrier. Increased efficiency of immobilization correlated with BC porosity-related parameters, which, in turn, depended on the size of oil droplets introduced into the culture medium. Moreover, changes in porosity-related parameters caused by the addition of oil or emulsion to the medium were observed when the cultures were conducted only under static conditions and not under agitated conditions. Conclusion: The application of oil- and emulsion-modified BCs as carriers significantly increased the efficiency of Y. lipolytica immobilization as compared to unmodified BC. The addition of oil or emulsion to the culture medium can be a simple but effective method to modify the porosity of BC-based carriers.

Antagonistic activity of Microbial Association of Kefir Grains and the areas of its usage

Glutamine Supplementation Ameliorates Chronic Stress-induced Reductions in Glutamate and Glutamine Transporters in the Mouse Prefrontal Cortex

Chronic immobilization stress (CIS) induces low levels of glutamate (Glu) and glutamine (Gln) and hypoactive glutamatergic signaling in the mouse prefrontal cortex (PFC), which is closely related to the Glu-Gln cycle. A Gln-supplemented diet ameliorates CIS-induced deleterious changes. Here, we investigated the effects of CIS and Gln supplementation on Glu-Gln cycle-related proteins to characterize the underlying mechanisms. Using the CIS-induced depression mouse model, we examined the expression of 11 proteins involved in the Glu-Gln cycle in the PFC. CIS decreased levels of glutamate transporter 1 (GLT1) and sodium-coupled neutral amino acid transporter (SNAT) 1, SANT2, SNAT3, and SNAT5. Gln supplementation did not affect the non-stressed group but significantly increased GLT1 and SNATs of the stressed group. By immunohistochemical analysis, we confirmed that SNAT1 and SNAT2 were decreased in neurons and GLT1, SNAT3, and SNAT5 were decreased in astrocytes in the medial PFC of the stressed group, but Gln-supplemented diet ameliorated these decrements. Collectively, these results suggest that CIS may cause depressive-like behaviors by decreasing Glu and Gln transportation in the PFC and that a Gln-supplemented diet could prevent the deleterious effects of CIS.

Use of Coffee Capsules as Support Material in Upflow Anaerobic Fixed Bed Reactors

Abstract The aim of this work is to evaluate the performance of upflow anaerobic fixed bed reactors filled with espresso coffee capsules to treat sanitary sewage. Three reactors (R1, R2 and R3) were constructed in blue PVC pipes measuring 30 cm height and 150 mm diameter and filled with coffee capsules made of aluminum and plastic. The sewage from the pre-treatment phase of the wastewater treatment plant of the Federal University of Lavras fed the system. Temperature, pH, alkalinity and volatile acids concentration, COD, TS, TVS and TSS of the influent and effluent were analyzed to evaluate the reactors performances. Statistics tests were run in the software Statistica 10. Changes occurred in the organic loading rates caused two different operating phases, one at an OLR of 2.1 kg COD m-3d-1 and another at 4.0 kg COD m-3d-1. The average temperature during the monitoring period was 18°C. In spite of the operating conditions variations, the reactors showed satisfactory performances, presenting COD efficiency removals up to 80% in both phases. The capsules characteristics were similar to other materials used as support. Hence, it is possible to utilize coffee capsules as support material in anaerobic reactors, providing satisfactory pollutants removal efficiencies.

Treating complexity in the older adult - the role of the geriatric giants

As people age, they accumulate medical conditions. Geriatric giants comprise a group of conditions that lead to significant mortality and morbidity and contribute to the complexity in treating geriatric patients. They are common and rarely occur in isolation. The 5 Is of geriatric giants are: iatrogenesis, immobility, instability, incontinence and impaired cognition. Consequences for the patient and their caregivers include loss of functional independence, institutionalisation and caregiver burnout. Primary care practitioners are often the first port of call for geriatric patients in South Africa and by asking a few key questions and performing a thorough examination; these conditions can be recognised early. Whilst there are often limitations to cure, the main aim is to maintain the older adult's functional independence as much as possible, and by following an organised management approach to each of these conditions, the quality of life of patients can be improved

Peripheral Neuropathies in Patients with Rhabdomyolysis: Clinical Characteristics and Electrodiagnostic Findings in the Acute/Subacute Stage

BACKGROUND: Rhabdomyolysis is a syndrome caused by injury to skeletal muscle and characterized by myalgia and swelling of the affected muscles. Peripheral nerve injury rarely occurs in patients with rhabdomyolysis. METHODS: We reviewed the medical records of 8 consecutive patients with peripheral neuropathies associated with rhabdomyolysis. We assessed the clinical characteristics and electrodiagnostic findings of eight patients. RESULTS: In seven patients, rhabdomyolysis occurred after prolonged immobilization. In one patient, blunt trauma was a cause of rhabdomyolysis. All patients presented with weakness and paresthesia in lower extremities and electrodiagnostic tests showed peripheral nerve injury suggesting sciatic neuropathy or lumbosacral plexopathy. Although rhabdomyolysis itself recovered completely in all patients, neurologic deficits from neuropathy recovered partially and slowly. CONCLUSIONS: Sciatic nerve or lumbosacral plexus was injured in all eight patients. Among the various causes of rhabdomyolysis, prolonged immobilization is associated with development of peripheral neuropathy.
