I read with great interest the study by TSCHOPP et al. [1]. They compared in a multicentre randomised study two groups of patients with primary spontaneous pneumothorax (PSP), in order to study the recurrence rate, the side-effects (mainly the pain) and the cost of two treatment modalities, thoracoscopic talcage (TT) or pleural drainage (PD). They found that, after 5 yrs of follow-up, 34% of PS...

The PSP and TSP have also increased productivity and reduced cycle time. SAIC has created a process for small software teams based on PSP principles. You’re meant to customize the out-of-the-box PSP process to meet individual and organizational needs. Our process uses all the PSP elements, such as personal design and code reviews, design standards, inspections, process improvement proposals, de...

Two patients with "pure akinesia" who showed the characteristic changes of progressive supranuclear palsy (PSP) at necropsy are described. They had akinesia but no rigidity or tremor, and ophthalmoplegia was not observed during the course of illness. The symptoms of "pure akinesia" was not improved by levodopa therapy but was considerably improved by L-threo-3,4-dihydroxy-phenylserine. At necro...

The silicon-on-insulator (SOI) CMOS technology has a number of advantages over the standard bulk CMOS technology, such as no latch-up effect, high speed and low power. The fully depleted SOI (FD-SOI) technology provided by OKI Electric Industry Co., Ltd. is realizing the full features of the advantages with lowest junction capacitance. Test element group (TEG) structures of transistors were fab...

Prognostic predictors have not been defined for progressive supranuclear palsy (PSP) and multiple system atrophy (MSA). Subtypes of both disorders have been proposed on the basis of early clinical features. We performed a retrospective chart review to investigate the natural history of pathologically confirmed cases of PSP and MSA. Survival data and several clinically relevant milestones, namel...

BACKGROUND Progressive supranuclear palsy (PSP) is a neurodegenerative disorder that is frequently mistaken for Parkinson's disease (PD) in its early stages. OBJECTIVE To compare balance measures using computerized posturography in patients with early PSP and early PD. METHODS We performed computerized posturography (SMART Balance Master; NeuroCom International, Inc, Clackamas, Ore) in 20 p...

OBJECTIVE Because it is often difficult to precisely diagnose and distinguish progressive supranuclear palsy (PSP) from corticobasal degeneration (CBD), multiple system atrophy-parkinsonism (MSA-P) and Parkinson's disease (PD) at the onset of the disease, we compared the patients and clarified the features of these diseases. METHODS We compared 77 PSP, 26 CBD, 26 MSA-P and 166 PD patients fro...

Objective The objective of the study was to assess magnetic resonance (MR) planimetric measurements and MR parkinsonism index (MRPI) in differentiating progressive supranuclear palsy (PSP) from Parkinson's disease (PD) using 1.5 and 3 T MRI scanner. Subjects and methods After ethical approval was obtained, analysis of 34 consecutive patients with PSP, 34 patients with PD and 34 healthy contro...

We report an interesting case demonstrating co-occurrence of radiological features of progressive supranuclear palsy (PSP) and corticobasal degeneration (CBD). The clinical features were typical of PSP but magnetic resonance imaging (MRI) showed both typical brainstem changes of PSP and an atypical pattern of cortical atrophy. While the MRI had markers of CBD, the clinical features were not cla...

OBJECTIVE Serum uric acid (UA) levels are reported to be decreased in patients with Parkinson's disease (PD) and multiple system atrophy (MSA). However, clinical correlates of serum UA levels are still unclear in PD-related disorders. We conducted a cross-sectional study to evaluate the associations between serum UA levels and disease duration, disease severity, and motor function among PD, MSA...
