Question: Abstract: During a 6-year period, 14 of 898 patients examined at a pediatric electromyographic laboratory had a compressive mononeuropathy. These included five injuries to the peroneal nerve, four to the sciatic nerve, two to the distal radial nerve, and one each to the deep palmar branch of the ulnar nerve, the musculocutaneous nerve, and the long thoracic nerve. A potentially preventable mechanism was identified in 9 of the 14 patients, including prolonged posture in three of the four sciatic and two of the peroneal neuropathies. Four other mononeuropathies were secondary to pressure from an orthopedic appliance or procedure (one injury to the musculocutaneous nerve, one to the long thoracic nerve, two to the peroneal nerve).

Question: Abstract: Placement of an unheated miniaturized oxygen electrode against the palpebral conjunctiva permits noninvasive measurement of tissue oxygen tension. In this study, the relationship between conjunctival oxygen tension (PcjO2) and standard cardiorespiratory variables was examined during a sequential resuscitation protocol after acute hemorrhage. Anesthetized dogs were rapidly bled to a mean arterial pressure of 40 mm Hg and then retransfused with the shed blood in a stepwise fashion. PcjO2 fell to 2% of control values after hemorrhage and did not return to prehemorrhage values until more than 90% of the shed blood had been reinfused. PcjO2 was among the last set of cardiorespiratory variables to return to control values during resuscitation and was the last noninvasive variable to normalize. The ratio of PcjO2 to arterial oxygen tension decreased from a prehemorrhage value of 0.76 +/- 0.05 (SEM) to 0.02 +/- 0.003 after hemorrhage, and did not increase to values greater than 0.50 until resuscitation was more than 90% complete. Conjunctival oxygen monitoring may play an important role in assessing the adequacy of resuscitation after acute hemorrhage.

Question: Abstract: In cases of exposure to unknown substances, analyzing environmental or biological samples for elevated levels of toxicants can be extremely complex. We assessed a method for prioritizing toxic substances according to the agreement between toxic-specific and incident-reported signs and symptoms by analyzing 25 reported case histories of exposure to inorganic toxicants. In all but one case, this analysis scheme successfully prioritized toxicants for subsequent analysis. Despite its limitations, the scheme is a substantial improvement over other available methods.
