Massive thrombosis of brachiocephalic veins and superior vena cava syndrome in a patient with non-small cell lung cancer treated with the epidermal growth factor receptor inhibitor erlotinib.

The superior vena cava (SVC) syndrome occurs when obstruction of this vessel interrupts venous return of blood from the head, upper extremities and thorax to the right atrium. Most cases of SVC syndrome result from neoplasia, especially from lung cancer, but other non-cancer-associated causes may include fibrosis caused by radiotherapy, collagen-vascular diseases, arteriovenous shunts or thrombosis as a complication of use of central venous catheters or devices. We report here the case of a 60-year-old woman with non-small cell lung cancer who was treated, after three lines of chemotherapy, with the epidermal growth factor receptor inhibitor erlotinib and subsequently presented to the hospital with abrupt onset of syncope, shortness of breath and cyanosis (face, neck and trunk). A CT scan of the chest demonstrated a massive thrombosis of both brachiocephalic veins and the SVC. The patient was treated with the systemic thrombolytic agent urokinase, with resolution of the clinical picture and no bleeding complications. The possible pathogenetic causes of thrombosis of the brachiocephalic veins and SVC syndrome in this case are discussed. It is possible that acute thrombosis may be associated with erlotinib use, even if it is likely that cancer may be the main cause of the thrombotic complication.

Upper gastrointestinal endoscopy: are preparatory interventions or conscious sedation effective? A randomized trial.

AIM: The fears and concerns are associated with gastroscopy (EGD) decrease patient compliance. Conscious sedation (CS) and non-pharmacological interventions have been proposed to reduce anxiety and allow better execution of EGD. The aim of this study was to assess whether CS, supplementary information with a videotape, or presence of a relative during the examination could improve the tolerance to EGD. METHODS: Two hundred and twenty-six outpatients (pts), scheduled for a first-time non-emergency EGD were randomly assigned to 4 groups: Co-group (62 pts): throat anaesthesia only; Mi-group (52 pts): CS with i.v. midazolam; Re-group (58 pts): presence of a relative throughout the procedure; Vi-group (54 pts): additional information with a videotape. Anxiety was measured using the "Spielberger State and Trait Anxiety Scales". The patients assessed the overall discomfort during the procedure on an 100-mm visual analogue scale, and their tolerance to EGD answering a questionnaire. The endoscopist evaluated the technical difficulty of the examination and the tolerance of the patients on an 100-mm visual analogue scale and answering a questionnaire. RESULTS: Pre-endoscopy anxiety levels were higher in the Mi-group than in the other groups (P<0.001). On the basis of the patients' evaluation, EGD was well tolerated by 80.7% of patients in Mi-group, 43.5% in Co-group, 58.6% in Re-group, and 50% in Vi-group (P<0.01). The discomfort caused by EGD, evaluated by either the endoscopist or the patients, was lower in Mi-group than in the other groups. The discomfort was correlated with "age" (P<0.001) and "groups of patients" (P<0.05) in the patients' evaluation, and with "gender" (females tolerated better than males, P<0.001) and "groups of patients" (P<0.05) in the endoscopist's evaluation. CONCLUSION: Conscious sedation can improve the tolerance to EGD. Male gender and young age are predictive factors of bad tolerance to the procedure.

[Endoscopic hemostasis in the treatment of bleeding peptic ulcer]. / L'emostasi endoscopica nel trattamento dell'ulcera peptica sanguinante.

Upper gastrointestinal bleeding is still an important clinical problem, even though about 80% of bleedings due to peptic lesions stop spontaneously. Starting from 1970, a lot of endoscopic hemostatic procedures has been developed and employed with good results, but, at present, the key problem is represented by the selection and management of the patients at highest risk of rebleeding. This work reviews both techniques and devices most commonly used, but at present none of them can be considered actually better than the other ones. According to the SIED (Società Italiana di Endoscopia Digestiva) guidelines, the techniques of choice should be cheap, effective, safe and easy to perform, the pivotal role in determining the success rate of endoscopic hemostasis being played by the endoscopist's experience.

[Assessment of anxiety levels in patients during diagnostic endoscopy]. / Valutazione dei livelli di ansia in pazienti sottoposti ad endoscopia diagnostica.

Patients with increased pre-endoscopic anxiety take advantage of the use of conscious sedation. However, the habit of using premedication varies according to the type of endoscopic examination. Aims of this study were: to evaluate whether different endoscopic procedures may have different effects on patient anxiety; and whether anxiety affects patient tolerance. 163 consecutive outpatients undergoing endoscopy (75 gastroscopy, 51 colonoscopy and 37 bronchoscopy) were interviewed to evaluate pre-endoscopy anxiety, by using the Spielberger State-Trait Anxiety Inventory. After endoscopy, endoscopists rated patient cooperation on a 10-cm visual analogue scale. Females had state and trait anxiety levels higher than males (50.49 +/- 1.37 vs 45.07 +/- 1.20, p < 0.01; and 44.46 +/- 1.06 vs 38.48 +/- 1.01, p < 0.01). Anxiety levels were not related with the type of endoscopic procedure. A direct relationship was observed between state and trait anxiety (p < 0.001). Patient cooperation to endoscopy was inversely related with both trait (p < 0.05) and state anxiety (p < 0.01). In conclusion, gastroscopy, colonoscopy and bronchoscopy seem to induce similar pre-endoscopy anxiety levels. Therefore, the different frequency in the use of intravenous sedation between bronchial and gastrointestinal endoscopy does not seem justified.
