The development of glossopharyngeal breathing and palatal myoclonus in a 29 year old after scuba diving
Palatal myoclonus is a rare movement disorder characterized by brief, rhythmic involuntary movements of the soft palate. Palatal myoclonus is further subdivided into “essential palatal tremor” (EPT) and “symptomatic palatal tremor” (SPT). EPT is characterized by involvement of the tensor veli palatini, myoclonus that might persist during sleep, as well as ear clicks, usually the patient’s presenting complaint. The MRI and neurological exam are normal in EPT. SPT is characterized by involvement of the levator veli palatini and myoclonus which consistently perseveres during sleep. The MRI shows olivary hypertrophy and clinical features may include ataxia, dysarthria and nystagmus, depending on the size of the lesion1. Glossopharyngeal breathing is a technique used by deep-sea divers to increase lung vital capacity, which is also useful in patients with ventilator dependence from poliomyelitis and Duchenne muscular dystrophy. To date there have been no reported cases of palatal myoclonus and glossopharyngeal breathing occurring simultaneously. We present the case of a 29 year-old female with palatal myoclonus and glossopharyngeal breathing after scuba-diving
Correlation of compliance with central line associated blood stream infection guidelines and outcomes: a review of the evidence
Background Clinical practice guidelines are developed to assist in patient care but the evidence basis for many guidelines has been called into question. Methods We conducted a literature review using PubMed and analyzed the overall quality of evidence and made strength of recommendation behind 8 Institute of Health Care (IHI) guidelines for prevention of central line associated blood stream infection (CLABSI). Quality of evidence was assessed by the American Thoracic Society (ATS) levels of evidence (levels I through III). We also examined data from our intensive care units (ICUs) for evidence of a correlation between guideline compliance and the development of VAP.Results None of the guidelines was graded at level I. Two of the guidelines were graded at level II and the remaining 6 at level III. Despite the lack of evidence, 2 of the guidelines (hand hygiene, sterile gloves) were given a strong recommendation. Chlorhexidine and use of nonfemoral sites were given a moderate recommendation. In our ICUs compliance with the use of chlorhexidine correlated with a reduction in CLABSI (p<0.02) but the remainder did not.Conclusions The IHI CLABSI guidelines are based on level II or III evidence. Data from our ICUs supported the use of chlorhexidine in reducing CLABSI. Until more data from well-designed controlled clinical trials become available, physicians should remain cautious when using current IHI guidelines to direct patient care decisions or as an assessment of the quality of care
