[Determinants of depression in 111 Italian patients with systemic sclerosis].

BACKGROUND: A high prevalence of depressive symptoms has been described in systemic sclerosis (SSc), but no clear association with organ involvement or objective indices of disease severity has been depicted. To date, no effort has been made to determine the prevalence of depressive symptoms in Italian patients with SSc or to clarify their cause. METHODS: One-hundred-eleven SSc patients were asked to fill in the Beck Depression Inventory (BDI) questionnaire, the scleroderma Health Assessment Questionnaire (sHAQ) and two additional questions assessing the patient's familiar support and the social consequences of the patient's change in physical appearnace. RESULTS: Thirty-seven subjects (33.4%) presented mild to severe depressive symptoms (BDI >/=17). On univariate analysis the diffuse cutaneous form of the disease (p=0.019), higher pulmonary systolic pressures on echocardiogram (p=0.016), lower FVC percentage of predicted values (p=0.022), higher sHAQ values (p<0.001) or higher VAS values for pain (p=0.007), lung involvement (p=0.02), Raynaud's phenomenon severity (p=0.002), ulcers severity (p=0.006) or disease severity (p<0.001), were associated with the presence of pathologic depressive symptoms. On multivariate analysis only the VAS for disease severity relevant to BDI scores (p=0.016). Social behaviour changes due to SSc-related physical involvement were reported in 14 patients (38%) with depressive symptoms (p=0,006) and were more likely to be observed in younger patients (p=0.001) with a more severe Raynauds's phenomenon (p=0.013). CONCLUSIONS: Mild to severe depressive symptoms are common in SSc patients especially in those with a worse perception of disease severity, these patients should be carefully monitored and a psychological assistance counselled whenever necessary.

[Percutaneous or surgical trachetomy. Prospective, randomized comparison of the incidence of early and late complications].

BACKGROUND: To compare early and late complications after either conventional surgical or percutaneous dilatational tracheostomy. DESIGN: Prospective, randomized study. SETTING: General intensive care unit and neuro-surgical intensive care unit in a university hospital. PATIENTS: 50 consecutive patients, requiring tracheostomy for prolonged mechanical ventilation. INTERVENTIONS AND MEASUREMENTS: Patients were randomly allocated to receive either surgical (surgical group, n = 25) or percutaneous dilatational tracheostomy (percutaneous group, n = 25). Occurrence of perioperative complication were carefully evaluated during ICU stay. Late complications were evaluated with both physical and endoscopic examination at 1, 3 to 6 months after tracheostomy. RESULTS: All surgical and percutaneous tracheostomies were successfully completed and no deaths directly related to the tracheostomy procedures were reported. Completion of the procedure required 41 +/- 14 min in the surgical group and 14 +/- 6 min in the percutaneous one (p < 0.0001). The incidence of early perioperative complications was higher in the surgical group (36%) than in percutaneous one (12%), (p < 0.05). The endoscopic follow-up demonstrated one segmental malacia and one stenosis of the trachea in the percutaneous group only (p = n.s.). Skin repair was better after percutaneous tracheostomy than in the surgical group (p < 0.01). CONCLUSIONS: In experienced hands, percutaneous dilatational tracheostomy is as safe and effective as the conventional surgical tracheostomy. The percutaneous technique is less time-consuming and has a lower rate of early infectious complications with better cosmetic results than the surgical technique.

[Monitoring of pediatric patients undergoing magnetic resonance diagnosis with a superconducting magnet].

Magnetic resonance imaging (MRI) has presented to anesthesiologists as unique challenge in patient monitoring because of its construction and principles of operation. Ferromagnetic materials within or near the scanner can distort the magnetic field, and monitoring wires act as antennae and this may result in image degradation. Nevertheless, monitoring is mandatory during MRI, especially in a child sedated or in general anesthesia. A monitoring system, made up of commercially available components, was assessed, and its effects on MR (1.5 tesla unit) image quality system determined. Variables monitored included: electrocardiogram and heart rate, (Sirecust 404, ECG cable set MR; Siemens, Enlanger, West Germany); blood pressure via automated sphygmomanometry (Press Mate BP-8800; Colin, Komaki, Japan); and continuous arterial saturation via pulse oximetry (Nellcor 100 E; Nellcor, Inc., Haywood, California). Fluid infusion rate was controlled by means of a plastic deliver (Dial-a-flo; Abbott Labs., Chicago, Illinois). Body temperature was maintained with a heat insulator blanket (Thermadrape, OR Concepts, Inc., Dallas, Texas). The monitoring technique described did not interfere with MRI function or produce image degradation.

New diagnostic and screening possibilities in the stenobliterative lesions of the deep visceral vessels.

The evolution and continuous improvement of the ultrasonic diagnostic devices allows an hemodynamic and morphological exploration of the deep abdominal vessels that until now seemed to be precluded to non invasive diagnostic techniques. For example, the angiodynography today advantageously substitutes classical urographic investigation during the initial screening of the hypertensive patients suspected of stenotic lesions of the renal arteries. In fact the ecocolordopplersonography allows not only a morphological evaluation of the parenchyma and of the renal vascular tree, but also supplies a quantitative measurement of the blood flow through the renal artery. Still more important are the possibilities offered by these devices in the study of the acute or chronic intestinal ischemia, in which until now a sure diagnosis was only possible using invasive techniques. Performing a study of the mesenteric vascularization urgently, sometimes is possible a decisive demonstration of an ischemic pathology where the clinical abdominal picture provides only uncertain diagnostic elements.

[Leiomyosarcoma of the stomach: contribution to case reports].

The authors illustrate two cases of gastric leiomyosarcoma (LMS) by themselves observed and they point out the anatomicopathologic and clinical appearances. Hemorrhagic sequels, presence of abdominal massa, canalization troubles often are the symptoms revealing a neoplasm, which therapy is a surgical exeresis composed by electric attitudes.

[An unusual case of atherosclerotic aneurysm of the trunk of the superior mesenteric artery, successfully treated with surgery].

A case of atherosclerotic aneurysm of the superior mesenteric artery is reported. This was located about 15 cm from its origin and immediately distal to the middle colic artery in a patient who had been operated on 4 years previously with aorto-iliac substitution for aneurysm of the same nature with ligature and section of the inferior mesenteric artery at the origin. Interruption of the latter created further technical problems solved with a serie of anastomoses that permitted the introduction of a good direct flow from the superior mesenteric respectively to the right colic and into an ileal branch which became a bridge or, rather, a "new mesenteric" assuring excellent pulsed flow into the underlying ileal branches, one of which anastomized at the ileocolic. This enabled direct, valid, pulsed flow to be resumed.

[Aneurysm of the popliteal artery. Prognostic and therapeutic criteria].

Experience of the management of 45 patients affected by popliteal artery aneurysms is reported. All patients, but one, underwent operative treatment. The importance of immediate surgical reconstruction whenever a popliteal artery aneurysm has been detected is stressed. In fact the most frequent complication represented by sudden thrombosis of the aneurysmatic sac and/or by peripheral embolization is generally followed by an irreversible closure of the vascular run off, determining the high rate of failures (28% in our experience) in spite of a prompt surgical reconstructive procedure.

[Association of rupture abdominal aneurysm and intestinal infarct].

The authors present one patient with ruptured abdominal aortic aneurysm (rAAA) who complicate with small bowel infarction and coproperitoneum; and two patients who suffered from rAAA and simultaneous colon infarction, successfully treated by one-stage operation. They comment upon this rare pathology and analyze hypothetical causes, considering the scanty literature about it.

[Problems of differential diagnosis of lymphoma and celiac disease. A case report].

An association between celiac disease and non-Hodgkin's lymphoma of the small intestine has been recognized for many years. Coeliac disease is characterized by an enteropathy sensitive to gluten, malabsorption of food and partial or total villous atrophy. Also malignant lymphoma may present with malabsorption and mucosal lesion similar to that found in coeliac patients. The diagnosis of lymphoma in coeliac patients can be extremely difficult because the presenting symptoms and histological lesion are similar, but the presence of a cluster of symptoms such as abdominal pain malabsorption, weight loss in patients older than 40 years with a history of poorly responsive coeliac disease should raise a suspicion of malignancy. We present a case of 55 year-old man with malignant lymphoma and coeliac disease surgically treated in our Institute for intestinal obstruction.

[Secondary aorto-enteric fistula].

Aortic graft fistula is a rare and life-threatening complication after aortic reconstruction. The incidence ranges from 0.5 to 4%, and even if the diagnosis and treatment is appropriate, the results of surgery are poor: mortality rate ranges from 14 to 70%. The optimal method of treatment is still controversial; prosthetic removal and extra-anatomic bypass has been advocated as the standard method, but more recently, because the high mortality rate associated with this procedure, some have prompted to recommend in situ aortic graft replacement as a more successful treatment. Personal experience with incidence (0.7%) outcome and mortality (57%) in 7 patients treated over a period of 6 years (1990-1996) is reported. Results from this group are compared with another group (6 patients) previously treated (1975-1982) for the same pathology. Our results after 10 years, show the same incidence (0.7 vs 0.6%) and an elevated and unchanged mortality (57 vs 66%). Better results in the management of aorto-enteric fistulas could be achieved with the removal of infected infrarenal aortic prosthetic grafts and in situ homografts replacement.
