Traumatic Clivus Epidural Hematoma: Case Report and Review of the Literature

BACKGROUND: Traumatic clival epidural hematoma is an extremely rare reported entity. CASE DESCRIPTION: We describe the case of a 26-year-old woman involved in a car accident who presented with a Glasgow Coma Scale score of 13, bilateral abducens palsy, bilateral numbness on the mandibular territory of the trigeminal nerve, and left hypoglossal palsy. Radiological examinations revealed a clival epidural hematoma. The patient was managed conservatively, with clinical improvement of her neurological condition. This is the first traumatic clival epidural hematoma reported in an adult. From a review of the literature, we found only 8 cases. CONCLUSION: The pathophysiology of these hematomas is still a subject of debate; occipitoatlantoaxial ligamentous instability may play a role in it. In one third of the cases, bilateral cranial nerve palsies were associated. Apparently, they have a benign outcome.

Lesões Traumáticas Iatrogénicas das Veias Femorais no Decurso da Cirurgia de Varizes

Traumatic lesions of the femoral veins during varicose veins surgery are very uncommon and they raise several therapeutic difficulties. They occur in 1/1000 cases of varicose veins operated. The authors describe four cases of lesions of this type that were seen and treated for the last six years, probably because there was an increase in the number of varicose veins operated on in the Lisbon area. The authors discuss the surgical options and they concluded that these complications can be minimized with good anatomical and surgical skills, specially of the saphenous-femoral and saphenous-popliteal junctions.

Falso Aneurisma Traumático da Aorta Infrarenal. A Propósito de um Caso Clínico

Abdominal aortic pseudoaneurysms are rare, particularly when they are related to blunt abdominal trauma. The authors report the clinical case of a 65 years old man with an abdominal aortic pseudoaneurysm related to a blunt abdominal trauma, that occurred three years ago. The patient complained of a diffuse abdominal pain, increased while walking. The diagnosis was confirmed by angiography and by angio-CT. An aortic resection and interposition graft was performed, according to the age of the patient and the low operative risk. A discussion on the therapeutic option was made, followed by a revision of the literature on the subject, and the authors conclude by emphasizing the need of a detection of this type of pathology, particularly in patients who had suffered in the past violent trauma.

Pseudoaneurisma Traumático da Aorta Abdominal. Caso Clínico

Os pseudoaneurismas da aorta abdominal são muito raros, principalmente quando associados a traumatismo abdominal fechado. Têm muitas vezes um comportamento clínico insidioso, com queixas dolorosas ou sinais compressivos de estruturas adjacentes. Os autores apresentam o caso clínico de um homem de 47 anos de idade que desenvolveu um pseudoaneurisma da aorta terminal após traumatismo abdominal fechado, na sequência de acidente de viação e que foi objecto de tratamento cirúrgico com êxito.

Fístulas Carótido-Cavernosas. Perspectivas de Diagnóstico e Terapêutica

Even though in clinical practice carotid cavernous fistulas (CCF) are not a frequent pathology, it should be a diagnostic hypothesis in face of a suggestive clinical presentation. We intended to review the diagnosis and the therapeutics, comparing them with the actual perspectives. Files of 25 patients with the diagnostic hypothesis of CCF, confirmed by conventional angiography in the HSAC Neuroradiology Department, were reviewed. In this group of patients, (5 males and 20 females), the fistulous aetiology was spontaneous in 10 and traumatic in 15. Clinically the symptom most often presented was diplopia (23 cases) and the most frequent encountered sign was ophthalmoplegia (20 cases). Of the Neuroradiologic investigation, CT scan (done to all patients) have shown an prominent superior ophthalmic vein as the most frequent abnormality. Angiographic study was based on Lasjaunias et al protocol (Surgical Neuroangiography, Vol. 2, Springer-Verlag). Surgery was the therapeutic approach for the traumatic fistulas; only 2 of the spontaneous were treated by endovascular route. Three patients are still under observation. In all the others cases there was a fistula exclusion.

Defying Standard Criteria for Digital Replantation: A Case Series

INTRODUCTION: There is much controversy regarding the current indications and contraindications for digital replantation. PRESENTATION OF CASE: Three patients with absolute contraindications for digital replantation according to classical criteria are presented (Case 1: multilevel amputation of the hand and fingers; Case 3: avulsion of the thumb; Case 4: index amputation proximal to the insertion of the flexor digitorum superficialis). In addition a patient with a very distal digital amputation (Case 2), whose indication for replantation is controversial is also presented. In all cases, the patients were replanted and showed good functional and aesthetical results. DISCUSSION: Most authors advocate that the classical indications for replantation have been validated by experience, are predicated on the potential for long-term function, and should be followed in most if not all cases. However, some surgeons have been adopting a more liberal attitude with good results. CONCLUSION: The clinical cases presented in this paper suggest that the standard criteria for digital replantation should not be followed rigidly but instead should be regarded as a general guide.

Abcessos Retrofaríngeos de Causa Traumática na Criança

Os abcessos retrofaríngeos constituem uma entidade clínica relativamente rara, grave e por vezes fatal, devido à sua localização anatómica e consequente potencial para complicações graves, pelo que requerem diagnóstico e terapêutica precoces e correctos. Predominam na criança, podendo a su etiologia ser traumática ou não traumática, sendo esta a mais frequente. Pela sua raridade, os autores apresentam três casos clínicos de abcessos retrofaríngeos de causa traumática em crianças com menos de cinco anos de idade, a propósito dos quais tecem considerações acerca da clínica, diganóstico e terapêutica desta patologia.

A Redução do Tempo de Pré-Admissão e da Duração do Internamento em Fisiatria é Custo-Efectiva na Reabilitação do Traumatismo Crânio-Encefálico?

Objectivos: Em doentes com traumatismo crânio-encefálico (TCE), o aumento da duração do pré-internamento (internamento em cuidados agudos hospitalares de outras especialidades, antes da admissão em Medicina Física e de Reabilitação) e do internamento no Serviço de Medicina Física e de Reabilitação pode não justificar a sua inclusão ou manutenção na reabilitação em internamento, podendo esta não ser custo-efectiva comparativamente a modelos em ambulatório. O objectivo principal deste trabalho foi avaliar o impacto da duração do pré-internamento e do internamento em Medicina Física e de Reabilitação nos ganhos de funcionalidade obtidos por doentes com TCE. Material e Métodos: Doentes internados por TCE em Medicina Física e de Reabilitação (MFR) entre 1/1/1996 e 31/12/2010 (pré-amostra n = 79). Critérios de inclusão: TCE; pré-internamento <6 meses; internamento em MFR >7 dias. Critérios de exclusão: défices neurológicos e músculo-esqueléticos antes do TCE; intercorrências que condicionassem o programa de reabilitação. Amostra n = 64. O género, idade e os tempos de pré-internamento e de internamento em MFR são as variáveis independentes. Com base nos registos de entrada e alta em MFR, analisou-se a variação de vários parâmetros funcionais (variáveis dependentes). Aplicaram-se modelos estatísticos lineares generalizados: regressão logística, regressão linear múltipla e regressão ordinal logística, nas variáveis com escalas binária, intervalar ou ordinal, respectivamente. Para testar se houve melhoria após o internamento em MFR, aplicou-se o teste paramétrico t para amostras emparelhadas. Resultados: Género (feminino: 32.81%, masculino: 67.19%); média de idades (34.73±14.64 anos); duração média (pré-internamento: 68.03±36.71 dias, internamento em MFR: 46.55±:29.23 dias). O internamento em MFR conduziu a ganhos estatisticamente significativos (p < 6.54x10-2) em todas as variáveis dependentes. A duração de pré-internamento tem uma influência não linear estatisticamente significativa na duração de internamento em MFR (estimativa DPI: 1.18, estimativa DPI2: -5.92x10-3, p DPI: 9.17x10-3, p DPI2: 1.52x10-2). A redução da duração de pré-internamento está associada a uma evolução mais favorável em 20 variáveis, das quais 10 com influência estatisticamente significativa (p < 0.12). O aumento do tempo de internamento em MFR está significativamente associado a maiores ganhos nas escalas MIF e Barthel (p < 4.31x10-3). Conclusões: A duração de pré-internamento tem uma influência não linear na duração do internamento em MFR e constitui um parâmetro de prognóstico funcional em reabilitação. A sua redução é custo-efectiva na reabilitação do TCE e recomenda-se que seja um factor a considerar na selecção de doentes para a reabilitação em internamento. O programa de reabilitação em internamento gera ganhos significativos de funcionalidade, estando uma duração maior associada a ganhos mais favoráveis.

Serum Zn Levels in Dysphagic Patients Who Underwent Endoscopic Gastrostomy for Long Term Enteral Nutrition

Background and aims: Dysphagic patients who underwent endoscopic gastrostomy (PEG) usually present protein-energy malnutrition, but little is known about micronutrient malnutrition. The aim of the present study was the evaluation of serum zinc in patients who underwent endoscopic gastrostomy and its relationship with serum proteins, whole blood zinc, and the nature of underlying disorder. Methods: From patients that underwent gastrostomy a blood sample was obtained minutes before the procedure. Serum and whole blood zinc was evaluated using Wavelength Dispersive X-ray Fluorescence Spectroscopy. Serum albumin and transferrin were evaluated. Patients were studied as a whole and divided into two groups: head and neck cancer (HNC) and neurological dysphagia (ND). Results: The study involved 32 patients (22 males), aged 43-88 years: HNC = 15, ND = 17. Most (30/32) had low serum zinc, 17/32 presented normal values of whole blood zinc. Only two, with traumatic brain injury, presented normal serum zinc. Serum zinc levels showed no differences between HNC and ND patients. There was no association between serum zinc and serum albumin or transferrin. There was no association between serum and whole blood zinc. Conclusions: Patients had low serum zinc when gastrostomy was performed, similar in HNC and ND, being related with prolonged fasting and unrelated with the underlying disease. Decrease serum zinc was unrelated with low serum proteins. Serum zinc was more sensitive than whole blood zinc for identifying reduced zinc intake. Teams taking care of PEG-patients should include zinc evaluation as part of the nutritional assessment, or include systematic dietary zinc supply.

A Homemade Snare: An Alternative Method for Mechanical Removal of Dirofilaria Immitis in Dogs

Canine dirofilariosis is a life-threatening parasitic disease that is increasingly reported worldwide. Once diagnosed the main treatment goals are to improve the animal's clinical condition and to eliminate all life stages of the parasite with minimal posttreatment side effects. This can be achieved through mechanical, surgical, or chemotherapeutical approaches. Currently, manual extraction is the preferred method to remove adult heartworms due to its diminished invasiveness, reduced damage to the vascular endothelium, and shortened anaesthesia duration. However, it remains an expensive technique that can be highly traumatic. To address this issue, a nontraumatic homemade catheter-guided snare was developed for heartworm removal by adapting and folding a 0.014-inch coronary wire (BMW, Abbott Vascular). Transvenous heartworm extraction was performed on a dog severely infected with adult heartworms by inserting the modified snare into a 6-F Judkins right coronary guiding catheter BMW (Cordis) and advancing it into the right ventricle under fluoroscopic guidance. Fifteen adult specimens of Dirofilaria immitis were successfully extracted from the pulmonary artery and right ventricle without complications. To assure the death of both larvae and adults, postoperative treatment was successfully managed using ivermectin, doxycycline, and melarsomine, with no recurrence after surgery.
