Choking is a life-threatening and not infrequent occurrence in psychiatric hospitals. There is, however, little information available about the risk factors or methods to prevent choking. We conducted a retrospective analysis of the 8 patients who had a cardiopulmonary arrest due to choking and received resuscitation at our hospital during the 6-year period from April 2005 to March 2011. The st...

Commentary Seizure clustering is a common occurrence in many types of epilepsy. As with any phenomenon distributed unevenly, the human mind strives to find explanations for periods of relative quiescence interspersed with periods of prominent activity. Women with epilepsy have consistently associated seizure clustering with the menstrual cycle, so much so that there is a name for the phenomenon...

Sir,—Elliott, Voyvodic and Brownridge recently reported an unexpected subarachnoid block in a parturient, despite careful aspiration testing and prior administration of local anaesthetic via a catheter, presumably located in the lumbar extradural space. 1 We recently described five similar cases of high spinal block produced by the initial test dose alone after negative aspiration testing. 2 We...

A 48-year-old white man who was healthy previously presented from an outside hospital with weakness of the bilateral lower extremities and right upper extremity. He awoke at 3 Am in morning on the day of initial presentation with unexplained urinary incontinence and diaphoresis. His symptoms resolved, and he went back to bed. At 7 Am, he dropped his daughter off at daycare; this was the last kn...

Three categories of tumor promoters and chemically related but inactive substances were tested for their effect on the cytotoxic activity of human blood lymphocytes against K562 and Daudi targets. Lymphocytes incubated overnight in the presence of phorbol esters 12-0-tetradecanoylphorbol-13-acetate and phorbol-12,13-dibutyrate [P(Bu)2] had enhanced function. Incu bation with 4-a-phorbol-12,13-d...

For most patients with multiple myeloma treatment is palliative and comprises combined melphalan and prednisolone. Despite several clinical trials the evidence on more intensive combinations is conflicting. Nevertheless, in younger patients the results of trials of high dose chemotherapy with bone marrow trans-plantation seem promising. Cytotoxic drugs have no established role in the palliative...

The effect of a-bromo-a-benzylmalodinitril (BBMD) on the oxygen evolution and on the ab­ sorption changes at 515 nm and 704 nm has been investigated in spinach chloroplasts. It has been found: 1. Under repetitive flash excitation conditions, where the back reaction around system II is practically excluded for kinetical reasons, BBMD does not restore the 515 nm absorption change in DCMU poisoned...
