Assessment of level of consciousness is very important in predicting patient's outcome from neurological illness. Glasgow coma scale (GCS) is the most commonly used scale, and Full Outline of UnResponsiveness (FOUR) score is also recently validated as an alternative to GCS in the evaluation of the level of consciousness. We carried out a prospective study in 97 patients aged above 16 years. We measured GCS and FOUR score within 24 h of Intensive Care Unit admission. The mean GCS and the FOUR scores were lower among nonsurvivors than among the survivors and were statistically significant (P < 0.001). Discrimination for GCS and FOUR score was fair with the area under the receiver operating characteristic curve of 0.79 and 0.82, respectively. The cutoff point with best Youden index for GCS and FOUR score was 6.5 each. Below the cutoff point, mortality was higher in both models (P < 0.001). The Hosmer-Lemeshow Chi-square coefficient test showed better calibration with FOUR score than GCS. A positive correlation was seen between the models with Spearman's correlation coefficient of 0.91 (P < 0.001).

Like many people, pilgrims have been traveling to high altitude for ages. Unlike other sojourners to high altitude, however, pilgrims in South Asia are often less aware of the dangers of traveling to high altitude. They are also often unaware of the simple medications to be taken while traveling and the importance of the rate of ascent at high altitude. Often they have preexisting comorbidities and are not well prepared. Much needs to be done to make them fully aware of the dangers of the journey they are about to undertake so that they can better prepare themselves.

Introduction: Painful neck swelling is a common emergency complaint but can present diagnostic challenges. Eagle syndrome is a rare clinical entity in which a pathologically elongated styloid process or ossified stylohyoid ligament produces a constellation of symptoms in the head and neck region. Case Report: We present the case of a 50-year-old male with a spontaneous, atraumatic fracture of an elongated styloid process associated with hematoma formation and radiological findings of airway impingement. Discussion: The classic triad for Eagle syndrome consists of unilateral cervicofacial pain, globus sensation, and dysphagia. Diagnosis of Eagle syndrome should be made based on a combination of physical examination and radiological findings. Treatment options vary based on severity of symptoms. Conclusion: Although more likely to be an indolent and progressive complaint, providers in the acute care setting should be familiar with Eagle syndrome due to the potential for a spontaneous fracture of an elongated styloid process to cause acute, painful neck swelling and life-threatening airway compromise.

Weekend AP admissions develop more severe complications requiring intensive care. Despite this, there was no weekend effect for in-hospital mortality for AP-related admissions.

Bhandari, Sanjeeb Sudarshan, Pranawa Koirala, Nirajan Regmi, and Sushil Pant. Retinal hemorrhage in a high-altitude aid post volunteer doctor: a case report. High Alt Med Biol. 18: 285-287, 2017.-High-altitude retinal hemorrhages (HARHs) are seen at altitudes more than 3000 m, are usually multiple, flame shaped, and adjacent to blood vessels. Development near the macula causes blurring of vision, otherwise, they are symptomless and self-limiting. They often develop during the first few days after ascent to high altitude and subjects often suffer from acute mountain sickness (AMS) or high-altitude cerebral edema (HACE). People going to high altitude for the first time are more susceptible to retinal hemorrhages than experienced climbers and high-altitude dwellers. We present a case of a 31-year-old male doctor who developed sudden unilateral blurring of vision without any other symptoms after 6 weeks of volunteering at a high-altitude aid post in Nepal. There were no features suggestive of AMS or HACE. All examinations were normal except for fundoscopic examination in the left eye, which determined macular retinal hemorrhage. Although he was reluctant to descend, he was counseled to descend and refrained from further ascent to higher altitude, which could accentuate hypoxemia and any strenuous activities that increase intraocular pressure. He recovered his vision after few weeks in Kathmandu and his retinal hemorrhages regressed. Hypoxia exacerbated by repeated bouts of rapid ascent to further higher altitudes may have contributed to his HARH. This suggests that unilateral retinal hemorrhages can develop even after several weeks at high altitude without concomitant AMS or HACE. People going to high altitude are reluctant to retreat, before reaching their target, when they suffer from HARH. The same is shown by a physician. So it is very important for healthcare professionals working at high altitudes especially in the Himalayas of Nepal to have a good knowledge about HARH and its proper treatment.

Background: Symptoms of psychosis such as hallucinations can occur at high or extreme altitude and have been linked to accidents on the mountain. No data are available on how to assess such symptoms in the field and what their prevalence or predisposing factors might be. Methods: In this field study at Everest Base Camp (5,365 m) in Nepal, 99 participants of organized expeditions underwent 279 assessments: The High Altitude Psychosis Questionnaire (HAPSY-Q), the Prodromal Questionnaire, 16-items (PQ-16), and the Mini International Neuropsychiatric Interview (M.I.N.I., psychosis section) were collected together with further clinical data. Statistical analysis was done for each phase, that is, altitude range of the climb, and overall data. Results: One of 97 climbers fulfilled the M.I.N.I. diagnostic criteria for psychosis during one acclimatization climb. At least one endorsed item on the HAPSY-Q and the PQ-16, indicating the presence of symptoms of psychosis in the absence of a psychotic disorders, were identified in 10/97 (10.3%) and 18/87 (20.7%) participants respectively. The scores of the HAPSY-Q and the PQ-16 were correlated (r = 0.268, p < 0.001). Odds ratio analysis identified an increased risk for accidents in individuals with endorsed items on the HAPSY-Q. Conclusions: The diagnosis of high altitude psychosis is rare in climbers during organized expeditions. Nevertheless, subdiagnostic symptoms of psychosis occurred in a significant proportion of climbers. Future research is needed to validate these pilot findings.

Diagnosis of HAPE can be challenging when the presentation deviates from usual natural history. Point of care ultrasonography serves as a great diagnostic tool in such settings. An umbrella treatment could be beneficial during such scenarios.
