Failure of Fluoroscopy and Success of Intravascular Ultrasound to Locate an Intracoronary Embolized Palmaz-Schatz Stent
We describe a patient in whom one half (disarticulated) Palmaz-Schatz stent was lost during a failed stenting procedure of an ostial left anterior coronary artery (LAD) stenosis. The embolized stent could not be located by fluoroscopy and was found in the left main coronary artery by intravascular ultrasound. The stent could not be removed using a retrieval device and was successfully deployed in the left main coronary artery by high-pressure balloon dilatation. Subsequently, LAD stenosis was successfully treated with deployment of two additional half Palmaz-Schatz stents
Local heparin delivery prior to coronary stent implantation: acute and six-month clinical and angiographic results
Stents increase smooth muscle cell proliferation, which may also lead to in-stent restenosis. A local delivery strategy provides higher drug concentration at the angioplasty site and may limit the proliferative response following stenting. Local heparin delivery was attempted in 35 patients following balloon angioplasty using an "over-the-balloon" style catheter (infusion sleeve). The infusion sleeve was successfully tracked and heparin was delivered in 33 (94%) patients. Heparin (1,000 IU/ml) was delivered under low (45 psi, 2 ml, n = 4), intermediate (75 psi, 4 ml, n = 11), and high (100 psi, 4 ml, n = 18) proximal infusion pressures. Stent placement was successful in all cases. Acute and in-hospital complications were a severe arterial spasm after heparin delivery, a non Q-wave myocardial infarction, and two vascular complications. Ten dissections were observed after PTCA and prior to heparin delivery. Of these dissections, 7 remained unchanged, 2 worsened, and 1 improved with local delivery. When heparin was delivered in the absence of dissection, no new dissections were observed. Of the 33 patients who received heparin, 30 (91%) had no symptoms and a negative exercise test at clinical follow-up. QCA analysis of 6-month follow-up angiograms, performed in 32 of 33 (97%) patients, demonstrated an acute gain of 1.98 +/- 0.67 mm, a late loss of 0.94 +/- 0.78 mm, a net gain of 1.04 +/- 0.78 mm, and a loss index of 0.48 +/- 0.32. Restenosis (> or = 50% stenosis) was observed in 4 of 32 (12%) patients. Local delivery of heparin via the infusion sleeve following PTCA and prior to stent deployment is feasible with an acceptable safety profile and a low clinical and angiographic restenosis rate at 6 months
Autologus peripheral stem cell transplantation in a patient with diffuse systemic sclerosis: our experience
The diffuse form of systemic sclerosis (SSc) can often lead to a rapidly progressive course with the involvement of the visceral organs which causes a severe prognosis. The 5-years cumulative mortality is between 30 and 60%, depending on the clinic form at the onset. Until now, no drug treatment has been proved to be efficacious against the progression of the disease or the regression of the fibrosis. Recently autologous peripheral blood stem cell (PBSC) transplantation has been found to be promising. We introduce the case of a patient, male, 56 years old, who came under our observation on February 2001, suffering from a SSc with a severe multisystem involvement of lungs, skin, heart and gastrointestinal tract, and a positive antibodies anti-Scl-70. The 8 months therapy, at first with iloprost and cyclophosphamide, then with bolus of cyclophosphamide, was ineffective, with a rapid worsening of the cutaneous and pulmonary involvement. Under the patient agreement we decided to carry out an autologous PBSC transplantation. On December 2001, we obtained the PBSC mobilization after the administration of cyclophsphamide and lenograstim and the PBSC recovery with two leucoaferesis procedures. On February 2002, we gave the conditioning therapy with: thiotepa, cyclophosphamide, fludarabine, rabbit antilymphocytic globulin; then we made the infusion of PBSC. The bone marrow recovery (GN >500 and PLT >20.000) arrived at the day + 10. For three months after the transplantion we made an antibacterial, antiviral and antifungin prophylaxis with valacocyclovir, co-trimoxazole and fluconazole. The one-year follow-up has shown an essentially good response with the improving of the skin involvement and of the subjective indicators of the disease, while the pulmonary involvement donât seen modified from the high dose therapy

G-CSF treatment for STEMI: Final 3-year follow-up of the randomised placebo-controlled STEM-AMI trial
Objective: To assess whether granulocyte colonystimulating factor (G-CSF) treatment induces a sustained benefit on adverse remodelling in patients with large anterior ST-elevation myocardial infarction (STEMI) and left ventricular (LV) dysfunction after successful reperfusion. Methods: The STEM-AMI Trial was a prospective, placebo-controlled, multicentre study. Sixty consecutive patients with a first anterior STEMI, who underwent primary percutaneous coronary intervention 2-12 h after symptom onset, with LV ejection fraction (LVEF) 6445% measured by echocardiography within 12 h after successful revascularisation (TIMI flow score 652), were randomised 1:1 to G-CSF (5 \u3bcmg/Kg body weight b.i.d.) or placebo. Clinical events and Major Adverse Cardiac and Cerebrovascular Event (MACCE) were monitored, and LVEF, LV end-diastolic (LVEDV) and end-systolic (LVESV) volumes, and infarct size were evaluated by MRI at the final 3-year follow-up. Results: Fifty-four patients completed the study, of whom 35 with MRI. No significant differences were found in mortality and MACCE between G-CSF and placebo-treated groups. The 3-year infarct size was not different between groups, whereas LVEDV was significantly lower in G-CSF (n=20) than in placebo (n=15) patients (170.1\ub18.1 vs 197.2\ub18.9 mL, respectively; p=0.033 at analysis of covariance). A significant inverse correlation was detected in G-CSF patients between the number of circulating CD34 cells at 30 days after reperfusion and the 3-year absolute and indexed LVEDV (\u3c1=-0.71, 95% CI -0.90 to -0.30, and \u3c1=-0.62, -0.86 to -0.14, respectively), or their change over time (r=-0.59, -0.85 to -0.11, and r=-0.55, -0.83 to -0.06, respectively). Conclusions: G-CSF therapy may be beneficial in attenuating ventricular remodelling subsequent to a large anterior STEMI in the long term. No differences have been detected in clinical outcome

Work related musculoskeletal disorders amongst therapists in physically demanding roles: Qualitative analysis of risk factors and strategies for prevention
Background Physiotherapy and occupational therapy are two professions at high risk of work related musculoskeletal disorders (WRMD). This investigation aimed to identify risk factors for WRMD as perceived by the health professionals working in these roles (Aim 1), as well as current and future strategies they perceive will allow them to continue to work in physically demanding clinical roles (Aim 2). Methods A two phase exploratory investigation was undertaken. The first phase included a survey administered via a web based platform with qualitative open response items. The second phase involved four focus group sessions which explored topics obtained from the survey. Thematic analysis of qualitative data from the survey and focus groups was undertaken. Results Overall 112 (34.3%) of invited health professionals completed the survey; 66 (58.9%) were physiotherapists and 46 (41.1%) were occupational therapists. Twenty-four health professionals participated in one of four focus groups. The risk factors most frequently perceived by health professionals included: work postures and movements, lifting or carrying, patient related factors and repetitive tasks. The six primary themes for strategies to allow therapists to continue to work in physically demanding clinical roles included: organisational strategies, workload or work allocation, work practices, work environment and equipment, physical condition and capacity, and education and training. Conclusions Risk factors as well as current and potential strategies for reducing WRMD amongst these health professionals working in clinically demanding roles have been identified and discussed. Further investigation regarding the relative effectiveness of these strategies is warranted
