Pathologies vasculaires lymphatiques: apport de la lympho-fluoroscopie [Lymphatic vascular pathologies: contribution of lympho-fluoroscopy].

Si l'examen clinique revêt une importance essentielle en lymphologie et exige des praticiens expérimentés, la lymphoscintigraphie et plus récemment la lympho-fluoroscopie au vert d'indocyanine constituent des moyens d'investigation précieux dans la prévention, le diagnostic et le traitement des pathologies vasculaires lymphatiques. L'intérêt de la lymphoscintigraphie réside dans l'analyse qualitative et quantitative de la migration des macromolécules par les vaisseaux lymphatiques et l'évaluation du secteur lymphatique profond. La lympho-fluoroscopie se distingue de la lymphoscintigraphie par l'obtention d'une cartographie détaillée des vaisseaux lymphatiques superficiels et d'images dynamiques en temps réel. Elle apporte à l'angiologue et au physiothérapeute des informations irremplaçables sur leur contractilité et la présence de dérivations compensatoires à privilégier lors du drainage lymphatique manuel. If clinical examination has an essential importance in lymphology disorders and requires experimented practitioners, lymphoscintigraphy and more recently green indocyanine lympho-fluoroscopy constitute precious complementary investigations in prevention, diagnosis, and treatment of lymphatic vascular pathologies. The lymphoscintigraphy interest lies in qualitative and quantitative analysis of macromolecules migration within lymphatic vessels and the deep lymphatic network. The lympho-fluoroscopy distinguishes itself from lymphoscintigraphy allowing real time superficial lymphatic vessels detailed mapping, gathering important information on their contractility, and the presence of compensatory derivations to be favored during manual lymphatic drainage to angiologist and physiotherapist.

Lymphatic drainage on healthy and neoplasic mammary glands in female dogs: Can it really be altered?

The purpose of this research was to study the mammary lymphatic drainage under a macroscopic and mesoscopic view, comparing the vascular pattern of healthy and neoplasic mammary glands injected with drawing ink alcoholic and fluorescein solutions, in 46 mongrel female dogs. The results pointed out that the thoracic gland is drained by the axillary lymph centre, but in mammary neoplasia either superficial cervical or ventral thoracic lymph centres can be involved. Cranial and caudal abdominal glands may be drained by the axillary, inguinofemoral and popliteal lymph centres. However, the popliteal drainage is specific for the healthy caudal abdominal mammary gland. The inguinal gland can be drained by both inguinofemoral and popliteal lymph centres in both neoplasic and healthy conditions. Regarding the mammary lymphatic communications, this research demonstrated that neoplasic glands present more types of anastomosis (40.9%), than healthy glands (33.33%), and an increase in contralateral anastomosis (50%) compared with healthy ones (33%). Given the data, the mammary neoplasia can change the lymphatic drainage pattern in terms of lymph centres and vascular arborization, thus forming new drainage channels and recruiting a larger number of lymph nodes. Lastly, some comments were made about the severity of a specific neoplasic mammary gland and conditions to be considered before making a decision in terms of the most adequate operative procedure, and suggestions for further investigations.

Efetividade da terapia fisica descongestiva na cicatrização de úlceras venosas

A venous ulcer is the most serious clinical manifestation of chronic venous failure, and the most frequent in lower limbs, accounting for 70% of all ulcers. Patients may suffer from this infirmity for several years without healing of the lesion if treatment is inadequate. The aim of this investigation was to verify the effectiveness of decongestive physical therapy in the healing of venous ulcers. This is a quasi-experimental, interventionist study, with paired, non-probabilistic sampling, composed of 50 patients divided into two groups: control and intervention, each composed of 25 patients. Both groups were identically treated for six months with daily dressings and the latter also underwent complex physical therapy consisting of a combination of the following techniques: manual lymphatic drainage, compression bandaging, lower limb elevation, myolymphokinetic exercises and skin care. The study was approved (Protocol no. 59/2007) by the Ethics Committee of the State University of Southeast Bahia. The Mann-Whitney and Chi-square tests were applied for data analysis. After statistical analysis the patients who underwent therapy showed a statistically significant difference with respect to wound contraction starting in the second month of treatment. Compared to the control, the intervention group showed a greater reduction in both pain and edema starting in the third and fourth month of therapy, respectively. To reinforce these findings, the mean percentage of tissue present at the base of the ulcer (granulation/fibrin ratio) was calculated. The intervention group showed greater granulation at the base of the ulcer compared to the control, significant from the second month of treatment on. It was observed in this study that lymphotherapy, when compared between the intervention and control groups, accelerated the healing process, and reduced pain and edema in the affected limbs. It is expected, therefore, that these results widen scientific knowledge and we suggest that this therapy be used 78 not only to reduce lymphedema, but also as a treatment option for venous ulcers, given its easy application and low cost. The data, therefore, demonstrated the importance of basic care on the part of a multiprofessional and transdisciplinary health team involved in the healing process of these infirmities, thereby contributing to better quality of life in these individuals

Influência da fisioterapia complexa descongestiva associada à ingestão de triglicerídeos de cadeia média no tratamento do linfedema de membro superior

OBJETIVO: Verificar a influência da utilização da fisioterapia complexa descongestiva associada à dietoterapia com triglicerídeos de cadeia média (TCM) como forma de intervenção no linfedema de membro superior (MS). MÉTODOS: Para a avaliação do linfedema, foram utilizadas cirtometria, volumetria, pregas cutâneas e quantidade de água corporal total. A Escala Visual Análoga (EVA) foi utilizada para avaliar as sensações de desconforto, peso e dor no MS. Participaram deste estudo dez mulheres mastectomizadas com linfedema de MS homolateral à cirurgia, com idade média de 65,9 ± 10,4 anos e índice de massa corpórea (IMC) de 26,8 ± 3,0kg/m² que, após avaliação nutricional, foram divididas aleatoriamente em dois grupos: Grupo Controle (n= 5), submetido ao tratamento fisioterapêutico constando da terapia complexa descongestiva (massagem clássica, drenagem linfática manual, bandagem compressiva e cuidados com a pele) três vezes na semana, durante quatro semanas; Grupo TCM (n= 5), submetido ao mesmo protocolo fisioterapêutico somado ao tratamento dietético diário com ingestão de TCM, por quatro semanas. RESULTADOS: Ao final da intervenção, a análise da cirtometria e da volumetria mostraram diferenças significativas entre os grupos (< 0,05), com maior redução do linfedema no Grupo TCM. Não houve diferença significativa nos valores das pregas cutâneas e da quantidade de água corporal total. A sensação de peso no membro superior, antes e após a intervenção, foi significativamente menor (< 0,05) no Grupo TCM. CONCLUSÕES: O tratamento fisioterapêutico somado à dietoterapia com ingestão de TCM em mulheres portadoras de linfedema de MS pós-cirurgia e tratamento de câncer de mama foi efetivo na involução desta condição.

Mid-humeral sentinel lymph node dissection in patients with primary cutaneous malignant melanoma

In rare cases, lymphatic drainage from the malignant melanomas in the upper extremity may follow an unpredictable pattern (outside the axillary nodes), and these aberrant sentinel nodes may represent the only site of regional lymph node metastases. The precise anatomical landmarks and technical aspects of surgical exploration of these aberrant sentinel lymph nodes are rarely described in the literature, including aberrant sentinel mid-humeral lymph nodes. This report describes a step-by-step dissection of the mid-humeral sentinel lymph nodes in two patients with a primary malignant melanoma in the upper extremity, identified by lymphatic mapping. Recognition of precise regional anatomy and following a special surgical technique makes the procedure safe and successful, thus avoiding local complications and allowing a prompt recovery.

Tc-99m-labeled dextran for mammary lymphoscintigraphy in dogs

Lymphoscintigraphy is the technique of choice for sentinel lymph node detection in women with early breast cancer, but there is limited information evaluating the value of this technique in animals. We investigated mammary lymphatic drainage in 25 young female mongrel dogs by intramammary injection of 18.5 MBq of Tc-99m-dextran (70,000 Da). Lymph node anatomical referencing was obtained using an external marker, bone scintigraphy, or scintiscanning the body contour. Cranial and caudal thoracic mammary glands drained into the cranial sternal lymph node and axillary lymph center. The cranial thoracic mammary gland also drained into the superficial cervical lymph node in two of five animals. The cranial abdominal gland was drained by the axillary lymph center. The caudal abdominal mammary gland was drained by the superficial inguinal lymph node in all animals and simultaneously by medial iliac lymph nodes in four of five animals. In one dog, this mammary gland was also drained by the mediastinal and the superficial cervical lymph nodes. The inguinal mammary gland was drained by superficial inguinal lymph nodes and simultaneously via the medial iliac lymph node in one animal. Lymphatic communications between lymph nodes were identified in 11 of 25 (44%) animals. Tc-99m-dextran mammary lymphoscintigraphy was easy and rapid to perform and may provide valuable information for further studies.

Cystic hygroma: characterization by computerized tomography

Lymphangiomas are benign nonencapsulated lesions composed of sequestered noncommunicating lymphoid tissue lined by lymphatic endothelium and are thought to be caused by congenital obstruction of lymphatic drainage. They are subclassified by vessel size, such as the capillary, which is rare and located in subcutaneous tissue, cavernous (located about the mouth and tongue), and cystic (cystic hygromas). The cystic hygromas show a predilection for the neck (75%) and maxilla (20%), and the remaining 5% arise in rare locations such as the mediastinum, retroperitoneum, bone, kidney, colon, liver, spleen and scrotum. Only 3%-10% of neck lesions extend into the mediastinum. In this paper, we report a rare case of cystic hygroma with a huge dimension discussing the use of computed tomography scanning for diagnosis.

Intraorbital anatomy of the koala (Phascolarctos cinereus)

This is the first documented study of the anatomical details of the contents of the normal koala orbit, excluding the bulbus oculi. Baseline data were established which are necessary for understanding and treating ocular disease in the koala (Phascolarctos cinereus). The anatomy of the orbital contents of the koala were examined and described from animals that presented dead or were euthanized for humane reasons. Dissections of the orbital cavity were performed under magnification. Polymethyl methacrylate (PMMA) casts of the nasolacrimal system and the vascular supply of the orbit were also made in order to study these systems. The superficial lymphatic drainage of the conjunctival tissues was studied by subcutaneous injection of Evan's Blue into the palpebral conjunctiva of a freshly deceased animal, and by Microfil casts of the efferent lymphatics. In general, the orbital contents of the koala are consistent with those of other carnivorous polyprotodont and herbivorous diprotodont marsupials.

Linfangiogénese no tecido adiposo em modelos de doença inflamatória crónica (asma e obesidade): uma abordagem por imunohistoquímica e lipidómica

O tecido adiposo é um órgão endócrino dinâmico, secretando factores importantes na regulação do metabolismo, fluxo vascular sanguíneo e linfático, e função imunológica, entre outros. Em caso de acumulação de tecido adiposo por ingestão de uma dieta gorda, ou por disfunção metabólica, os adipócitos podem desencadear uma reacção inflamatória por falha na drenagem linfática, acumulando-se mediadores inflamatórios, os quais potenciam a propagação da reacção. Assim, questiona-se uma potencial associação entre o aumento de tecido adiposo na obesidade, hipóxia adipocitária e estimulação da linfangiogénese. Além disso, a expressão de adipocinas varia de acordo com a distribuição do tecido adiposo (subcutâneo, TAS e visceral, TAV). Deste modo, pretende-se com este estudo contribuir para o aumento do conhecimento sobre os complexos mecanismos moleculares subjacentes à linfangiogénese. Ensaios com ratinhos da estirpe C57Bl/6J (modelo de obesidade) e BALB/c (modelo de asma e obesidade), divididos em grupos submetidos a dieta normal e dieta rica em gordura. Avaliação semi-quantitativa da expressão tecidular de LYVE-1 (marcador da linfangiogénese) por imunohistoquímica em material embebido em parafina, no TAS e TAV, e cromatografia líquida de ultra-performance acoplada de espectrometria de massa (UPLC-MS) para análise da expressão plasmática de ceramida e esfingosina-1-fosfato (S1P). No modelo de obesidade observou- -se diminuição do número de vasos linfáticos e expressão de LYVE-1 ao longo do tempo no TAV, e aumento de ambos os parâmetros e hipertrofia adipocitária no TAS. As concentrações de ceramida e S1P corroboram a existência de um processo inflamatório nos ratinhos em estudo, ainda que numa fase muito inicial. No modelo de asma e obesidade, após 17 semanas de tratamento, observou-se incremento da linfangiogénese no TAV, mas não no TAS. A resposta inflamatória avaliada através dos diferentes parâmetros permite afirmar que num estadio inicial de obesidade a proliferação linfática poderá estar a ser retardada pela hipertrofia adipocitária. A libertação de adipocinas será observada apenas numa fase posterior, desencadeando todo o processo inflamatório que incrementará a proliferação linfática. Adicionalmente, é possível sugerir que a maior pressão à qual o TAV se encontra sujeito não favorece a proliferação linfática, pelo menos num estadio incial.
