Objective.-Ulnar nerve compression, the Guyon's canal syndrome, is more unusual than carpal tunnel disorders. An exceptional case of a patient with vascular and neurogenic signs and symptoms is described.Patient Presentation.-A 26-year-old female physiotherapist presented with neurogenic and arteriovenous signs and symptoms involving the right hand. The patient described fourth fi nger and wrist pain with fl exion, and pain and itching extending to arm and forearm. Sensations worsened when exposed to air conditioning. Enlarged vessels were noted in the medial aspect of the fourth digit; trauma occurred 8 years earlier during attempts to open a nail polish container.Methods.-Color fl ow, duplex-Doppler ultrasonography (US) of the subclavian to digital vessels was performed using 3-to 13-MHz transducers. Interpretation focused on fl ow waveforms obtained with the hand open and closed, having the left extremity as reference. Thermography was performed with camera Flir 15, room temperature at 21°C (70°F) and relative humidity at 48%.Results.-Right subclavian to digital arteries had high diastolic fl ow with opened hand. Hand closure interrupted diastolic fl ow except in the ulnar circulation to the fourth digit. Common digital arteries feeding digits 3-4 and 4-5 had signifi cantly more diastolic fl ow than the artery feeding digits 2-3. Diastolic fl ow through a dilated ulnar artery despite hand closure was associated to a millimetric arteriovenous fi stula in the fourth fi nger. Hyperthermia saturating at 35°C (95°F) showed channel-like images over the ulnar nerve and artery and fourth digit, compared with 20°C (68°F) for digit 2.Conclusions.-US and thermography demonstrated high fl ow and hyperthermia associated with a fourth digit fi stula and abnormal vessels, and ulnar artery dilatation likely associated with ulnar nerve injury. A coadjuvant diagnosis of Guyon's canal syndrome at the wrist was raised.

Raynaud's phenomenon is one of the most common disorders of the blood vessels, which usually affects fingers and toes. Raynaud's disease, also called primary Raynaud's phenomenon, is diagnosed when the cause is unknown, whereas Raynaud's syndrome or secondary Raynaud's phenomenon occurs as a skin manifestation of concomitant disease. The most common trigger is exposure to cold. Specific clinical features allow a quick diagnosis. Raynaud's phenomenon usually does not require pharmacologic treatment, but in some cases symptoms are severe and pharmacotherapy is necessary. Calcium channel blockers are usually used as a first-line treatment. Alternative forms of therapy include angiotensin-converting-enzyme inhibitors, α1-adrenergic blockers, phosphodiesterase-5 inhibitors, endothelin antagonists, nitrates, antioxidants, statins, botulinum toxin, and even autologous fat grafting. StReSzczeNieObjaw Raynauda jest jedną z najczęstszych reakcji skurczowych naczyń krwionośnych, zazwyczaj dotyczy palców rąk i stóp. Choroba Raynauda, inaczej zwana pierwotnym objawem Raynauda, jest rozpoznawana, gdy przyczyna schorzenia jest nieznana. Zespół Raynauda lub wtórny objaw Raynauda współtowarzyszy innym chorobom. Najczęstszym czynnikiem prowokującym skurcz naczyń jest ekspozycja na zimno. Charakterystyczny obraz kliniczny zwykle pozwala na szybkie ustalenia rozpoznania. Objaw Raynauda u większości chorych nie wymaga leczenia farmakologicznego, ale u niektórych osób objawy są nasilone i farmakoterapia staje się niezbędna. Leki z grupy antagonistów wapnia są często stosowane w leczeniu pierwszego rzutu. Alternatywne formy terapii obejmują: inhibitory konwertazy angiotensyny, leki α1-adrenergiczne, inhibitory fosfodiesterazy 5, antagonistów endoteliny, azotany, przeciwutleniacze, statyny, toksynę botulinową, a nawet autologiczne przeszczepy tkanki tłuszczowej.

Resumo: A termografia é uma tecnologia não invasiva que pode ser aplicada para o diagnóstico complementar de alterações no sistema circulatório, como o Fenômeno de Raynaud (FR). O objetivo deste estudo foi aplicar um protocolo baseado na Diferença Distal Dorsal -DDD para identificação do FR. O método utilizado foi de pesquisa exploratória com 100 voluntários na faixa etária entre 18 a 60 anos, de ambos os gêneros, com autonomia de decisão. Os participantes responderam a uma anamnese e foram submetidos à coleta dos dados com câmera termográfica. O ambiente foi mantido com temperatura de 23°C. Em seguida, as mãos foram imersas até o nível do carpo em recipiente com água a 10°C durante 60 segundos. As imagens foram registradas imediatamente e 10 minutos pós-imersão. A normalidade dos dados foi testada através do teste de Komolgorov-Smirnov. As diferenças entre médias ou medianas foram apreciadas pelo Teste T independente e Teste de Man Whitney respectivamente. As análises foram feitas pelo software SPSS Versão 21.0. Na análise dos resultados, primeiramente os participantes foram divididos em dois grupos a partir da DDD, positiva (DDD>0) ou negativa (DDD<0). Os resultados mostram diferença estatística entre os processos circulatórios dos dois grupos. A temperatura do dedo mínimo foi a mais baixa e a da palma da mão a mais alta nos dois momentos. O grupo com DDD<0 teve menor ganho de temperatura ao longo do tempo. Os resultados deste estudo indicaram que a DDD é um critério válido para verificar o gradiente de temperatura no estudo do FR. Assim, uma das possibilidades quanto ao uso da termografia seria a aplicação desta tecnologia em patologias que afetam o sistema circulatório, como o Fenômeno de Raynaud. Este é caracterizado pela resposta exagerada da vasoconstrição. Verificam-se alterações na coloração de mãos, pés, nariz e orelhas, algumas vezes seguidas de queixa dolorosa. Afeta cerca de 3 a 5% da população em geral [5], podendo alcançar 20% da população em regiões de clima frio [6].Para a detecção do Fenômeno de Raynaud, a termografia deve avaliar as diferenças de temperatura na superfície da pele para determinar o fluxo sanguíneo na microcirculação [4], [7].Existem estudos envolvendo o FR em doenças autoimunes, comparação entre tecnologias e efeitos de medicações no seu controle. Porém, os parâmetros dos protocolos são diversos. Devido a isto, alguns autores obtiveram resultados positivos, enquanto outros não
