CPR in a diving bell is difficult. It is taught by diving companies and training institutes but has not been subjected to the tenets of evidence based medicine. The diving bell lacks space as well as a flat hard surface to lay the patient on and therefore conventional methods of administering CPR are not possible. The diver is hung from a pulley tied to the diver's harness, and the bell flooded with water to reduce pooling of blood. Airway is established using a cervical collar to hyperextend the neck and inserting an appropriate oropharyngeal airway...

Pregnant women, when employed in physically demanding occupations, may encounter difficulties in carrying out their work throughout pregnancy. Many such "blue collar" workers are unable to proceed in strenuous work during advanced stages of pregnancy. However, scientific evidence is not sufficient to support the widely accepted assumption of health risks due to the hard work during pregnancy. Therefore, in Israel, as long as pregnancy is normal, and the good health of both the mother and fetus is maintained, such workers are not entitled to sick leave or any other form of compensation...

1. The best-documented implants have a threaded solid screw-type design and are manufactured from commercially pure (grade IV) titanium. There is good evidence to support implants ≥ 6 mm in length, and ≥ 3 mm in diameter. 2. Integrity of the seal between the abutment and the implant is important for several reasons, including minimization of mechanical and biological complications and maintaining marginal bone levels. Although the ideal design features of the implant-abutment connection have not been determined, an internal connection, micro-grooves at the implant collar, and horizontal offset of the implant-abutment junction (platform switch) appear to impart favorable properties...
