To successfully implement a hazard analysis critical control point plan, prerequisite programs are essential. Sanitation standard operating procedures are an important part of such a plan and can reduce contamination levels so that food safety and quality are not adversely affected. Noncontact surfaces in the shell egg processing plants can serve as a reservoir of cross-contamination. The objec...

IN the recent past a number of blood pressure recorders for clinical use, and especially during anaesthesia, have been described (Molyneux and Pask, 1953; Simpson, 1956). It seemed, however, that these recorders had several disadvantages and that there was a place for an instrument that was cheap, simple and not a possible source of an explosion when used in the vicinity of explosive anaestheti...

T HE SINGLE incontrovertible indication for transfusion of frozen-stored red blood cells (FSR BC) is: to provide readily available rare donor blood for patients allosensitized to high-frequency donor antigens. Other alleged indications have not been adequately documented. It is useful to examine the background for so restrictive a definition. In 1950, it was first demonstrated that human red bl...

BACKGROUND The near exclusive use of praziquantel (PZQ) for treatment of human schistosomiasis has raised concerns about the possible emergence of drug-resistant schistosomes. METHODOLOGY/PRINCIPAL FINDINGS We measured susceptibility to PZQ of isolates of Schistosoma mansoni obtained from patients from Kisumu, Kenya continuously exposed to infection as a consequence of their occupations as ca...

Bottom-up urban water demand forecasting based on empirical data for individual water end uses or micro-components (e.g., toilet, shower, etc.) for different households of varying characteristics is undoubtedly superior to top-down estimates originating from bulk water metres that are currently performed. Residential water end-use studies partially enabled by modern smart metering technologies ...

BACKGROUND Obsessive-compulsive disorder (OCD) has distinct symptom dimensions with possibly subtle differences in the underlying neurobiology. One behavioral habit, smoking, has been widely investigated in psychiatric disorders, though received less attention in OCD. Here, we aimed to investigate the relationship between symptom dimensions and smoking behavior in OCD. SUBJECTS AND METHODS OC...

OBJECTIVE While artisanal mining takes place in casual framework and with total ignorance of good practices, few studies have focused on the origin of hazards specific to each workplace constitutive of this exploitation facility. Nevertheless, this study is a condition of an efficient occupational health and safety control in this sector. MATERIALS AND METHOD We took the effort to identify di...

To determine how the presence of generalised airflow limitation due to chronic obstructive lung disease affects the recognition of simulated upper airway obstruction, a study was carried out in 12 patients (mean (SD) age 57 (7) years) with chronic obstructive lung disease (FEV1% predicted 53 (22), range 21-70) and 12 matched control subjects. Patients and control subjects performed maximal insp...

This study compared the differences in clinical outcome between an endoscopic (67 of 70) and two-incision (41 of 49) technique used to reconstruct tom anterior cruciate ligaments (ACL) using a double-looped semitendinosus and gracilis (DLSTG) graft. In both techniques, the graft was placed without roof impingement, the looped end of the graft was fixed around a post with bone compaction, and th...
