Remission and Recovery in the Treatment for Adolescents With Depression Study (TADS): Acute and Long-Term Outcomes

ObjectiveWe examine remission rate probabilities, recovery rates, and residual symptoms across 36 weeks in the Treatment for Adolescents with Depression Study (TADS).MethodThe TADS, a multisite clinical trial, randomized 439 adolescents with major depressive disorder to 12 weeks of treatment with fluoxetine, cognitive–behavioral therapy, their combination, or pill placebo. The pill placebo group, treated openly after week 12, was not included in the subsequent analyses. Treatment differences in remission rates and probabilities of remission over time are compared. Recovery rates in remitters at weeks 12 (acute phase remitters) and 18 (continuation phase remitters) are summarized. We also examined whether residual symptoms at the end of 12 weeks of acute treatment predicted later remission.ResultsAt week 36, the estimated remission rates for intention-to-treat cases were as follows: combination, 60%; fluoxetine, 55%; cognitive–behavioral therapy, 64%; and overall, 60%. Paired comparisons reveal that, at week 24, all active treatments converge on remission outcomes. The recovery rate at week 36 was 65% for acute phase remitters and 71% for continuation phase remitters, with no significant between-treatment differences in recovery rates. Residual symptoms at the end of acute treatment predicted failure to achieve remission at weeks 18 and 36.ConclusionsMost depressed adolescents in all three treatment modalities achieved remission at the end of 9 months of treatment.

Quantification of the expression level of integrin receptor alpha(v)beta3 in cell lines and MR imaging with antibody-coated iron oxide particles.

Targeted imaging requires site-specific accumulation of a contrast agent (CA), and the properties of that agent must be selected according to the abundance of the target to obtain a signal above the detection limit of the instrument. However, numerical estimates of receptors per cell are rarely found in the literature. Integrin receptors would be particularly promising targets because of their accessibility from the blood stream and expression on activated neovascular endothelial cells. We systematically estimated the number of integrin receptors of cell lines and primary cells by flow cytometry analysis. Since integrin receptors are heterodimeric molecules, and alpha(v) forms complexes with various beta subunits, the numbers of alpha(v) and beta(3) subunits are therefore dissimilar. The observed values are 3 . 10(3)-1.4 . 10(4)/cell for alpha(v), and 5.3 . 10(2)-1.1 . 10(4)/cell for beta(3). Despite the low number of exposed receptors, we show that up to single-cell MR visualization can be achieved with the use of iron oxide beads complexed with antibodies as CAs.     

Arthroscopy of traumatic hemarthrosis following sports injuries. A 5 year analysis

This retrospective study was made to evaluate the significance of different sports activities that cause variable haemarthrosis with intraarticular lesions of the knee joint. Throughout 1984 to 1988 arthroscopy was performed in 337 patients with acute haemarthrosis. The average time between trauma and arthroscopy was 8 days. ACL rupture was diagnosed in most of these cases. Regarding the different types of sport activities ACL lesions were found in skiers (74%), other winter sports (47%), soccer (53%), tennis and squash (58%), athletics (41%) and indoor (61%). Peripheral meniscus tears associated with haemarthrosis were found in 36% and patellar dislocations in 8%. Isolated MCL ruptures were diagnosed clinically and arthroscopy was not performed in these cases. Throughout 1987 isolated ACL ruptures were fixed by reattachment. This technique was not continued any longer and ACL replacement by patellar tendon as bone-ligament-bone was performed routinely since 1988 in those patients, who required surgery. 56 patients required ACL reconstruction following conservative treatment because of ACL deficiency, when they went back to sports activities. Longitudinal peripheral meniscus tears were fixed by the scape in inside-out technique.     

Knee joint hemarthrosis--differential diagnostic considerations for planning an operation

From 1980 to the end of 1988, arthroscopy has been performed on 620 patients with acute hemarthrosis of the knee joint. Of all the intraarticular lesions, 89.4% required surgery. Arthroscopy has changed in the last decade from diagnostic screening to invasive instrumentation for exact operative planing and alternative operative techniques. Hemarthrosis in stable knee joints was caused by minor lesions (7.84%) that did not require surgical procedures. Seventy-three patients had traumatic patellar dislocations--in 33 cases associated with chondral or osteochondral fractures. In 54.8% of the isolated medial retinacular ruptures, simple suture was performed in 14 cases--3 times arthroscopically and 11 times open, combined with lateral retinacular release without redislocation following. Associated chondral fracture indicated surgery in all cases. Isolated meniscus pathology (12.48%) was treated by arthroscopy alone, and refixation of the medial meniscus was carried out using the inside-out technique in 27 cases. Arthroscopic elevation of lateral tibia plateau fracture--indicated by type II fracture according to the AO classification--was performed in 3 cases with excellent results, and was associated with screw fixation and image intensification in 2 patients. Intercondylar eminence fracture is an excellent indication for arthroscopic refixation in the presence of the mono- or two-fragment type of fracture. ACL rupture is the main intra-articular pathology (64.8%) for hemarthrosis of the knee joint, which was diagnosed as an acute injury within the 1st week following trauma (51.04%). Anterior instability can be detected clinically if a careful examination with the Lachman test, combined with the missing end-point and pivot-shift test, is performed.(ABSTRACT TRUNCATED AT 250 WORDS)     

Syndesmosis transfixation screw

Instability of the distal tibia-fibular joint necessitates the implant of a fibular tibial transfixation screw. The screw should be placed 2 cm above the anterior syndesmosis. The angle of insertion is 30 degrees upwards from dorsal in relation to the frontal plane. If tibiofibular stability cannot be maintained following anatomical reconstruction of the fibula the transfixation screw must engage the medial tibial cortex. This is imperative, since the transfixation screw cannot withstand the biomechanical forces during motion and bearing of load if the screw penetrates only three corticals.     

Telmisartan and irbesartan therapy in type 2 diabetic patients treated with rosiglitazone: effects on insulin-resistance, leptin and tumor necrosis factor-alpha.

The aim of our study was to investigate the metabolic effect of telmisartan and irbesartan in subjects treated with rosiglitazone, a well-known insulin-sensitizing drug, in order to clarify the direct metabolic effects of the two former drugs. Patients were enrolled, evaluated, and followed at 3 Italian centers. We evaluated 188 type 2 diabetic patients with metabolic syndrome (94 males and 94 females in total; 49 males and 46 females, aged 56+/-5, treated with telmisartan; and 45 males and 48 females, aged 55+/-4, treated with irbesartan). All had been diabetic for at least 6 months, and glycemic control by the maximum tolerated dietary changes and maximum tolerated dose of oral hypoglycemic agents had been attempted and failed in all cases. All patients took a fixed dose of rosiglitazone, 4 mg/day. We administered telmisartan (40 mg/day) or irbesartan (150 mg/day) in a randomized, controlled, double-blind clinical manner. We evaluated body mass index (BMI), glycemic control (HbA1c fasting plasma glucose and insulin levels [FPG, and FPI, respectively], and homeostasis model assessment [HOMA] index), lipid profile (total cholesterol [TC], low density lipoprotein-cholesterol [LDL-C], high density lipoprotein-cholesterol [HDL-C], and triglycerides [TG]), systolic and diastolic blood pressure (SBP and DBP), tumor necrosis factor-alpha (TNF-alpha), and leptin during the 12 months of this treatment. No BMI change was observed after 6 or 12 months in either group. Significant decreases in HbAlc and FPG were observed after 6 months in the telmisartan group, and after 12 months in both groups. The decrease in HbA1c and FPG at 12 months was statistically significant only in the telmisartan group. A significant decrease in FPI was observed at 12 months in both groups, and this decrease was significantly greater in the telmisartan group. Significant decreases in the HOMA index were observed at 6 and 12 months in both groups, and the decrease in the HOMA index after 12 months was significantly greater in the telmisartan group than in the irbesartan group. Significant changes in SBP, DBP, TC, and LDL-C were observed after 6 and 12 months in both groups. Significant decreases in TNF-alpha and leptin levels were observed after 6 months in the telmisartan group, and after 12 months in both groups. In conclusion, in this study of patients with type 2 diabetes mellitus and metabolic syndrome, telmisartan seemed to result in a greater improvement in glycemic and lipid control and metabolic parameters related to metabolic syndrome compared to irbesartan. These observed metabolic effects of different angiotensin type 1 receptor blockers could be relevant when choosing a therapy to correct metabolic derangement of patients affected by metabolic syndrome and diabetes.

Fine-needle aspiration biopsies of breast masses. An additional experience with 1153 cases (1985 to 1988) and a meta-analysis.

A series of 1153 fine-needle aspiration biopsies (FNAB) of breast masses obtained during the period 1985 to 1988 in one institution was examined. The following diagnostic accuracy values were found: sensitivity, 93.0%; specificity, 92.4%; predictive positive value, 93.7%; and efficiency, 92.8%. These results were compared with a previously published series for the period 1976 to 1984. The diagnostic accuracy values did not differ significantly between the two series.
