Family relations and eating disorders. The effectiveness of an integrated approach in the treatment of anorexia and bulimia in teenagers: results of a case-control systemic research

This article presents the results of a broader clinical research into the effectiveness of integrated treatments in teenage eating disorders, carried out at the Complex Operative Unit of Psychotherapy (Unità Operativa Complessa or U.O.C.) of the Department of Psychiatric Sciences and Psychological Medicine in collaboration with the Department of Neuropsychiatric Science for Child Development (Dipartimento di Scienze Neuropsichiatriche dell'Età Evolutiva), both at the "La Sapienza" University of Rome. The hypothesis of this research project is that in diagnosticable situations such as anorexia or bulimia, an integrated and multidisciplinary treatment, which combines medical-nutritional interventions and family psychotherapy, allows better results than a single kind of treatment, which is the usual medical- nutritional intervention supported by psychiatric counselling. Twenty-eight cases (16 of bulimia and 12 of anorexia) were selected and then subdivided, with a randomized distribution, into two (experimental and control) homogeneous groups of 14 patients. The grouping variables were the diagnosis, the disorder's seriousness and duration, BMI, gender, age, family composition and social status. The variables which have been examined in this article are the clinical parameters, which were valuated in accordance with the DSM IV-TR criteria, and relational parameters which were explored through the use of the W.F.T. Test (Wiltwyck Family Tasks). These parameters were tested at beginning as well as at the end of the therapies, in both the experimental group and the control group. Statistical analysis has shown that the experimental group, which was followed with the integrated treatment, experienced a significant improvement of the parameters as related to dysfunctional family interaction modalities, and that this improvement was correlated to the positive evolution of the clinical parameters. This improvement was not present or not of the same degree in the control group. The results, moreover, demonstrate the effectiveness of an integrated systemic treatment based on a complex approach compared to a reductionist approach.

Safety and efficacy of repeat transradial access for cardiac catheterization procedures

To determine the safety and efficacy of repeat transradial cardiac catheterization, 1,362 consecutive transradial procedures were examined. Repeat transradial procedures were identified (group I, n = 73) and compared with index procedures (group II, n = 1,289). Baseline patient characteristics, procedure success rates (100% vs. 97.9%; P = NS), complication rates (0% vs. 0.08%; P = NS), and procedure times (23.9 +/- 27.3 min vs. 18.2 +/- 14.7 min; P = NS) were similar between groups. This study suggests that repeat transradial catheterization procedures can be performed safely and successfully in appropriately selected patients.

Adjunctive therapies in the cath lab. Use of combination glycoprotein IIb/IIIa inhibitor and direct thrombin inhibitor drugs to support percutaneous coronary stent placement in a patient with renal insufficiency and heparin-induced thrombocytopenia

An 81-year-old woman with a history of prior coronary artery bypass surgery, heparin-induced thrombocytopenia with "white clot" syndrome, and renal insufficiency presented with unstable angina. She was referred for cardiac catheterization. Complex percutaneous revascularization of the native circumflex coronary artery was performed using stents. A combination of tirofiban and lepirudin was used with dosing adjusted for renal insufficiency. The hospital course was uncomplicated and the patient was discharged on the fourth hospital day. This is only the second report of the combination use of direct thrombin inhibitor and glycoprotein IIb/IIIa receptor inhibitor.

Final results of a randomized trial comparing the NIR stent to the Palmaz-Schatz stent for narrowings in native coronary arteries

The NIR stent is a novel second generation tubular stent that was designed to overcome some of the limitations of the earlier Palmaz-Schatz (PS) stent design. The NIR Vascular Advanced North American (NIRVANA) trial randomized 849 patients with single coronary lesions to treatment with the NIR stent or the PS stent. The study was an "equivalency" trial, designed to demonstrate that the NIR stent was not inferior to (i.e., equivalent or better than) the PS stent, for the primary end point of target vessel failure (defined as death, myocardial infarction, or target vessel revascularization) by 9 months. Successful stent delivery was achieved in 100% versus 98.8%, respectively, with a slightly lower postprocedural diameter stenosis (7% vs. 9%, p = 0.04) after NIR and PS stent placement, respectively. Major adverse cardiac events (death, myocardial infarction, repeat target lesion revascularization) were not different at 30 days (4.3% vs. 4.4%). The primary end point of target vessel failure at 9 months was seen in 16.0% of NIR versus 17.2% of PS patients, with the NIR proving to be equal or superior to the PS stent (p <0.001 by test for equivalency). Angiographic restudy in 71% of a prespecified cohort showed no significant difference in restenosis (19.3% vs 22.4%). Thus, the NIR stent showed excellent deliverability with slightly better acute angiographic results and equivalent or better 9-month target vessel failure rate when compared with the PS stent.

Transradial cardiac catheterization in elderly patients

The safety and efficacy of transradial cardiac catheterization in elderly patients is unknown. This study examines procedure success rates for transradial catheterization in appropriately selected patients < 70 (n = 195) and >/= 70 (n = 83) years old. Elderly patients were less likely to be selected for the transradial approach (46% vs. 61%; P = 0.05). Although patients >/= 70 years old were more often female (39.7% vs. 24.1%; P = 0.008) and had a smaller body surface area (1.89 +/- 0.18 vs. 2.01 +/- 0.24 m2; P = 0. 001), procedure success rates did not differ (95.1% vs. 94.8%; P = NS). Procedure-related variables including procedure time (15.4 +/- 12.6 vs. 16.1 +/- 11.6 min; P = NS), amount of radiographic contrast (90.1 +/- 31.9 vs. 86.4 +/- 29.8 cc; P = NS), and number of catheters used (1.5 +/- 0.9 vs. 1.5 +/- 0.7; P = NS) were similar between groups. We conclude that transradial catheterization can be safely and effectively performed in selected elderly patients. Cathet. Cardiovasc. Intervent. 51:287-290, 2000.

Coronary angioplasty with or without stent implantation for acute myocardial infarction. Stent Primary Angioplasty in Myocardial Infarction Study Group

BACKGROUND

Coronary-stent implantation is frequently performed for treatment of acute myocardial infarction. However, few studies have compared stent implantation with primary angioplasty alone.

METHODS

We designed a multicenter study to compare primary angioplasty with angioplasty accompanied by implantation of a heparin-coated Palmaz-Schatz stent. Patients with acute myocardial infarction underwent emergency catheterization and angioplasty. Those with vessels suitable for stenting were randomly assigned to undergo angioplasty with stenting (452 patients) or angioplasty alone (448 patients).

RESULTS

The mean (+/-SD) minimal luminal diameter was larger after stenting than after angioplasty alone (2.56+/-0.44 mm vs. 2.12+/-0.45 mm, P<0.001), although fewer patients assigned to stenting had grade 3 blood flow (according to the classification of the Thrombolysis in Myocardial Infarction trial) (89.4 percent, vs. 92.7 percent in the angioplasty group; P=0.10). After six months, fewer patients in the stent group than in the angioplasty group had angina (11.3 percent vs. 16.9 percent, P=0.02) or needed target-vessel revascularization because of ischemia (7.7 percent vs. 17.0 percent, P<0.001). In addition, the combined primary end point of death, reinfarction, disabling stroke, or target-vessel revascularization because of ischemia occurred in fewer patients in the stent group than in the angioplasty group (12.6 percent vs. 20.1 percent, P<0.01). The decrease in the combined end point was due entirely to the decreased need for target-vessel revascularization. The six-month mortality rates were 4.2 percent in the stent group and 2.7 percent in the angioplasty group (P=0.27). Angiographic follow-up at 6.5 months demonstrated a lower incidence of restenosis in the stent group than in the angioplasty group (20.3 percent vs. 33.5 percent, P<0.001).

CONCLUSIONS

In patients with acute myocardial infarction, routine implantation of a stent has clinical benefits beyond those of primary coronary angioplasty alone.

Successful treatment of a saphenous vein graft perforation with an autologous vein-covered stent

A 52-year-old man with a history of prior coronary bypass surgery suffered recurrent angina and underwent percutaneous placement of a stent within the midportion of the saphenous vein graft to the marginal branch of the left circumflex coronary artery, which was complicated by a significant perforation. The perforation was successfully closed using an NIR stent covered with a segment of autologous antecubital vein. Subsequent surgical exploration confirmed successful closure of the perforation. Cathet. Cardiovasc. Intervent. 48:382-386, 1999.

Transradial cardiac catheterization in patients with prior brachial artery cutdown

The safety and efficacy of transradial cardiac catheterization in patients with prior ipsilateral brachial cutdown is not known. Using standard techniques we performed transradial catheterization in 278 consecutive patients, of which 63 had prior brachial cutdown. All patients had a strongly palpable radial pulse and a negative Allen's test. Although patients with prior cutdown were older and had a higher incidence of hypertension and prior coronary artery bypass surgery, there was no significant difference in success rates for transradial catheterization (93.6% vs. 95.3%; P = NS). There were no periprocedural complications. Brachial artery occlusion was responsible for only two unsuccessful catheterization attempts. We conclude that, with careful preprocedural screening, ipsilateral transradial cardiac catheterization can be successfully performed in a majority of patients with prior brachial cutdown.

Acute and nine-month clinical outcomes after "suboptimal" coronary stenting: results from the STent Anti-thrombotic Regimen Study (STARS) registry

OBJECTIVES

This registry collected the 30-day and 9-month clinical outcomes of patients whose coronary stent implantation was suboptimal, and compared them with the cohort of patients with "optimal" stenting in the randomized portion of the STent Anti-thrombotic Regimen Study (STARS) trial.

BACKGROUND

Although "optimal" stenting combined with an aspirin and ticlopidine regimen carries a low (0.5%) incidence of subacute stent thrombosis, only limited data are available for patients in whom stents are deployed suboptimally.

METHODS

In the STARS, 312 (15.9%) of 1,965 patients enrolled were excluded from participation in the randomized trial based on a perceived "suboptimal" result of coronary stenting. Of these, 265 patients met prespecified criteria for suboptimal stenting, and were followed in a parallel registry, which was compared with the randomized STARS optimal stenting cohort. The primary end point was a 30-day composite of death, emergent target lesion revascularization, angiographic thrombosis of the target vessel without revascularization and nonfatal myocardial infarction (MI) unrelated to direct procedural complications.

RESULTS

Registry patients had a similar frequency of the primary end point compared with the overall randomized cohort (3.0% vs. 2.2%), with this end point correlating to use of multiple stents, smaller final lumen diameter and absence of ticlopidine from the poststent regimen. Overall 30-day mortality (1.1% vs. 0.06%, p = 0.009) and periprocedural non-Q wave MI (8.7% vs. 4.2%, p = 0.003) were more frequent in registry patients, and appeared to be related to acute procedural complications. Clinical restenosis was significantly higher for registry patients (26.8% vs. 16.0%, p = 0.001), relating to greater prevalence of independent predictors such as smaller final lumen diameter and multiple stent use.

CONCLUSIONS

In the STARS registry, the inability to perform optimal stenting correlated with smaller final lumen diameter and longer stent length. With ticlopidine-containing regimens, the acute clinical results of "suboptimal" stent deployment are clinically acceptable, although they are not quite as good as those of optimal stenting using similar drug therapy.

Myocardial ischemia resulting from spontaneous dissection in a patient with massive bilateral sinus of valsalva aneurysms

We describe a patient with large sinus of Valsalva aneurysms involving both the left and right coronary sinuses. Spontaneous dissection of the left coronary artery occurred, causing unstable angina, a complication heretofore not associated with this disease. Successful surgical reconstruction of the aortic root, aortic valve replacement, and coronary bypass grafting were performed. Pathology revealed cystic medial necrosis.

An unusual complication during deployment of a Multi-Link stent

The use of intracoronary stents has greatly impacted on the practice of interventional cardiology. Complications due to equipment failure during deployment of stents are rare but potentially serious. We report a case of a malfunctioning Multi-Link delivery system and the successful treatment of the resulting complications.

A clinical trial comparing three antithrombotic-drug regimens after coronary-artery stenting. Stent Anticoagulation Restenosis Study Investigators

BACKGROUND

Antithrombotic drugs are used after coronary-artery stenting to prevent stent thrombosis. We compared the efficacy and safety of three antithrombotic-drug regimens - aspirin alone, aspirin and warfarin, and aspirin and ticlopidine - after coronary stenting.

METHODS

Of 1965 patients who underwent coronary stenting at 50 centers, 1653 (84.1 percent) met angiographic criteria for successful placement of the stent and were randomly assigned to one of three regimens: aspirin alone (557 patients), aspirin and warfarin (550 patients), or aspirin and ticlopidine (546 patients). All clinical events reflecting stent thrombosis were included in the prespecified primary end point: death, revascularization of the target lesion, angiographically evident thrombosis, or myocardial infarction within 30 days.

RESULTS

The primary end point was observed in 38 patients: 20 (3.6 percent) assigned to receive aspirin alone, 15 (2.7 percent) assigned to receive aspirin and warfarin, and 3 (0.5 percent) assigned to receive aspirin and ticlopidine (P=0.001 for the comparison of all three groups). Hemorrhagic complications occurred in 10 patients (1.8 percent) who received aspirin alone, 34 (6.2 percent) who received aspirin and warfarin, and 30 (5.5 percent) who received aspirin and ticlopidine (P<0.001 for the comparison of all three groups); the incidence of vascular surgical complications was 0.4 percent (2 patients), 2.0 percent (11 patients), and 2.0 percent (11 patients), respectively (P=0.01). There were no significant differences in the incidence of neutropenia or thrombocytopenia (overall incidence, 0.3 percent) among the three treatment groups.

CONCLUSIONS

As compared with aspirin alone and a combination of aspirin and warfarin, treatment with aspirin and ticlopidine resulted in a lower rate of stent thrombosis, although there were more hemorrhagic complications than with aspirin alone. After coronary stenting, aspirin and ticlopidine should be considered for the prevention of the serious complication of stent thrombosis.

Peripheral vascular complications of coronary angioplasty by the femoral and brachial techniques

In order to monitor the incidence and types of peripheral vascular complications in a single institution, we prospectively entered 1,579 coronary angioplasty cases into a computer data base during the years 1991 and 1992. Various periprocedural risk factors were analyzed. The patients were followed closely to identify complications that occurred outside the laboratory or after discharge from the hospital. Peripheral vascular complications occurred in 37 patients (2.37%) and included hematoma 20 (1.27%), retroperitoneal bleeding 7 (.44%), false aneurysm 6 (.38%), occlusion 1 (.06%), infection 2 (.13%), and cholesterol emboli 1 (.06%). Risk factors for complications by multivariate analysis were older age, female gender, and clinical evidence of peripheral vascular disease. Other factors potentially related to vascular trauma or bleeding tendency that were not risk factors in this series were clinical presentation, use of heparin or thrombolytic agents, blood clotting parameters, and arterial sheath size. There was no significant difference between the femoral and brachial approaches in frequency of complications (2.5% vs. 1.6%), but femoral complications tended to carry greater morbidity.

Left atrial ball thrombus: review of clinical and echocardiographic manifestations with suggestions for management

Left atrial ball thrombus is an infrequent clinical syndrome, which can have a catastrophic outcome but can be readily treated when recognized. It is usually a complication of long-standing rheumatic mitral stenosis. Symptomatic presentation is variable: fragmentation of the thrombus followed by peripheral embolization will produce ischemia or infarction of myocardium, brain, viscera, or extremities; random, intermittent, partial, or total occlusion of the mitral valve orifice may cause syncope, pulmonary congestion, and occasionally sudden death in other patients. Embolic and obstructive phenomena may also occur together. Cardiac physical findings usually suggest mitral stenosis; variability in the intensity of the diastolic rumble is common. Two-dimensional echocardiography is the gold standard for identifying ball thrombus. Cardiac catheterization provides assessment of coronary artery status when needed. The outcome of untreated ball thrombus is unlikely to be favorable. The results of anticoagulation and thrombolysis are unpredictable and potentially as harmful as no treatment at all. Current evidence although scant suggests that prompt surgical removal of the free thrombus, often in conjunction with mitral valve repair or replacement, is the appropriate therapeutic course in most patients.

Angioplasty of a large aortocoronary bypass graft utilizing a single oversized balloon catheter

Angioplasty of large saphenous vein grafts may present problems because of unavailability of adequately sized balloon dilatation catheters. We report a case of successful PTCA of a left anterior descending graft by using a 5 mm balloon and a standard 8F guiding catheter.

Massive left atrial thrombus: a possible paraneoplastic complication of breast carcinoma

We describe a patient with long-standing rheumatic mitral valve disease, left atrial dilatation, and a precommissurotomy history of left atrial thrombus. Following operation she was maintained on daily aspirin as an antithrombotic measure. For 6 years she had no evidence, echocardiographically, of left atrial thrombus. She underwent surgery for apparently nonmetastatic breast cancer in early 1986. In May 1986 the left atrium was echocardiographically clear. At approximately the same time, recurrence was found at the suture line. In October 1987, two metastatic lung lesions and a very large left atrial mass were detected by computed tomography. The atrial mass was surgically removed and found to be a thrombus. There was a striking temporal correlation between dissemination of carcinoma and development of a massive atrial thrombus.

Coronary reperfusion and Bezold-Jarisch reflex (bradycardia and hypotension)

This study reports the occurrence of bradycardia and hypotension (Bezold-Jarisch reflex) induced by myocardial reperfusion. Among 92 patients undergoing interventional catheterization for intracoronary thrombolysis in an early phase of acute myocardial infarction, left anterior descending, right coronary, and left circumflex (LC) arteries were identified as the "infarct vessel" in 44, 41, and 7 cases, respectively. The Bezold-Jarisch reflex occurred in 15 of 23 patients (65%) after right coronary recanalization and in 1 of 34 patients after left anterior descending recanalization. The reflex also was observed in 4 (22%) of 18 patients with nonoccluded or nonrecanalized right coronary arteries. The average time from onset of symptoms to right recanalization was significantly shorter (p less than 0.01) among patients in whom the reflex did not develop. Atropine, postural changes, or temporary pacing, or all 3, were generally sufficient to control symptoms. The findings of this study are substantially parallel to those reported by others and confirm that reperfusion of the inferoposterior myocardium is capable of stimulating a cardioinhibitory reflex. Follow-up data available in 15 patients with occluded and recanalized right coronary arteries indicate that the occurrence of the Bezold-Jarisch reflex after reperfusion is not a reliable predictor of myocardial salvage.

Successful removal of papillary endocardial fibroma

We report a case of systemic embolization secondary to a small papillary endocardial fibroma, a rare cardiac tumor. It was attached to a chords of the mitral valve by a short stalk. The tumor was successfully excised and the mitral valve was preserved. Two-dimensional echocardiography played the major role in the diagnosis of this small endocardial tumor.

The use of injectable nitroglycerin in the cardiac catheterization laboratory. Nitroglycerin in cardiac catheterization

At our institution, injectable nitroglycerin (TNG) has been employed during cardiac catheterization since 1976. Initially, it was primarily used in patients undergoing a provocative test for coronary spasm with ergonovine maleate. After the initial favorable experience, the use of injectable TNG became routine.
