Laboratory diagnosis of pulmonary embolism: value of increased levels of plasma D-dimer and thrombin--antithrombin III complexes

Plasma D-dimer (DD) and thrombin--antithrombin III complex (TAT) were measured with ELISAs in 99 patients investigated by 102 ventilation--perfusion lung scintigraphy because of suspected pulmonary embolism. High-probability lung scan was associated with increased DD (more than 500 ng/ml) and TAT (more than 4.1 ng/ml) levels (sensitivity of 100 and 70%, respectively). The corresponding figures of specificity were 81 and 42%. In the 56 patients with low-probability or indeterminate probability scans, 31 (55%) had DD concentrations of less than 500 ng/ml. These preliminary data suggest that a plasma DD concentration of less than 500 ng/ml might rule out the diagnosis of pulmonary embolism in suspected patients with an inconclusive lung scanning.     

Intestinal infarction caused by carcinoid associated elastic vascular sclerosis: early presentation of a small ileal carcinoid tumour.

We describe a patient with extensive ischaemic necrosis of the ileum as a result of elastic vascular sclerosis (EVS). A 2 cm carcinoid tumour was located nearby with microscopic evidence of spread to regional lymph nodes. Severe intestinal ischaemia caused by carcinoid associated EVS may be the presenting feature of small carcinoid tumours resulting in their early diagnosis.     

Randomized trial of Codetron for pain control in osteoarthritis of the hip/knee

Patients suffering from pain due to osteoarthritis of the hip and knee participated in a double-blind placebo controlled trial using daily Codetron home care units for 6 weeks over the tibial, saphenous, popliteal and sciatic nerves, and tender points. Seventy-four percent of patients in the real Codetron (Group A) and 28% of the patients in sham Codetron (Group B) improved their pain level more than 25% as measured by visual analogue scale. The difference in pain improvement in the two groups was statistically significant (p less than 0.02 using Fisher's exact probability ratio). Other functional parameters proved to be insensitive to change in this study. This is highly suggestive of beneficial effect of nonhabituating Codetron as a complementary modality in the therapy of chronic pain conditions such as osteoarthritis.     

The Victim Care Service: a program for victims of sexual assault

Sexual victimization is a singularly traumatic event. At times, however, the implicit danger of the trauma experience itself gets exaggerated. For the victim the more lasting damage frequently stems from how he or she was treated by friends, family, health care providers, and public authorities following the incident. Treating the victimized patient as quickly and sensitively as possible is essential to minimizing the potential for further victimization. The Emergency Department at Boston City Hospital is frequently the site for the acute management of sexual assault victims. The Victim Care Service is designed to prevent secondary traumatization of such victims. The five-phase program and the fundamental assumptions upon which the phases are based are presented.     

Primary arteriovenous fistula between common iliac vessels: ultrasound, computer tomographic, and angiographic findings--a case report

A giant aneurysm of the right common iliac artery presenting with an arteriovenous fistula (AVF) between the iliac artery and iliac vein and deep venous thrombosis of the right lower extremity is reported. The clinical signs and the radiologic and surgical management of the condition are discussed. In addition a brief review of the literature is given.     

Chronic thromboembolic occlusion in the adult can mimic pulmonary artery agenesis

In the first 100 patients operated on for C T-E PH, three were referred with the diagnosis of UPAA having been made elsewhere. We found that many features of these two conditions are so similar that differential diagnosis is very difficult. Shared features may include findings on chest x-ray film, pulmonary angiography, CT scan and MRI studies. Since the two conditions vary substantially with respect to the methods of potential surgical correction, recognition of this possible differential diagnostic dilemma is important.     

Is a paediatrician required at caesarean section?

In a series of 460 consecutive deliveries there were 55 caesarean sections (mainly under epidural anaesthesia) without evidence of fetal distress and with a cephalic presentation. There was no statistically significant difference in the frequency of resuscitation in this group compared with 296 spontaneous vertex deliveries. It is concluded that a paediatrician is not routinely required at caesarean section under epidural provided there is no fetal distress and the presentation is cephalic.
