Hypovolemia is known to be a predisposing factor of decompression illness (DCI) while diving. The typical clinically impressive neurological symptoms of DCI may distract from other symptoms such as an incipient hypovolemic shock. We report the case of a 61-year-old male Caucasian, who presented with an increasing central and peripheral neural failure syndrome and massive hypovolemia after two risky dives. Computed tomography (CT) scans of the chest and Magnetic resonance imaging scans of the head revealed multiple cerebral and pulmonary thromboembolisms...

Ran Arieli, Abraham Marmur
Vascular bubble models, which present a realistic biophysical approach, hold great promise for devising suitable diver decompression procedures. Nanobubbles were found to nucleate on a flat hydrophobic surface, expanding to form bubbles after decompression. Such active hydrophobic spots (AHS) were formed from lung surfactants on the luminal aspect of ovine blood vessels. Many of the phenomena observed in these bubbling vessels correlated with those known to occur in diving. On the basis of our previous studies, which proposed a new model for the formation of arterial bubbles, we now suggest the biophysical model presented herein...

CASE DESCRIPTION An 11-year-old English Cocker Spaniel was evaluated because of chronic progressive ataxia of the hind limbs. CLINICAL FINDINGS The dog had no history of previous illness, and findings of physical examination and laboratory tests were unremarkable. Neurologic examination revealed that the dog was ambulatory with severe ataxia of the hind limbs. Proprioception was decreased in the right and left hind limbs (right affected more than left), and spinal reflexes were bilaterally unremarkable. Moderate signs of pain were detected during palpation of the lumbar portion of the vertebral column...

BACKGROUND: Spontaneous spinal epidural hematoma (SSEH) is a rare neurosurgical emergency. It presents as acute spinal cord compression and usually requires surgical decompression. The patients who will benefit most from decompression surgery are unknown and the factors associated with prognosis remain controversial. The purpose of our study was to identify the clinical features, treatments, and main factors related to the prognosis of SSEH. METHODS: We reviewed the records of 24 patients treated for SSEH from September 2010 to January 2016 at West China Hospital...

BACKGROUND: Interspinous spacer/implants like the Device for Intervertebral Assisted Motion (DIAM™) are controversially yet commonly used in the surgical treatment of lumbar degenerative pathologies. Criticism is based on ill-defined indications, lack of superiority over decompression, and a poorly understood mechanical effect. Yet, continued use by surgeons implies their perceived clinical merit. We examined radiographic spinal alignment for 12 months, and pain and function for 24 months, after DIAM-augmented surgery to improve the understanding of the mechanical effect relating to clinical outcomes in patients...

BACKGROUND: The list of complications reported after decompressive craniectomy (DC) and cranioplasty is progressively increasing. Nonetheless, the exact incidence of these events is still ill-defined. Problems affecting skin flaps after DC and cranioplasty have never been accurately analyzed in papers and their impact on patients' prognosis is largely underestimated. METHODS: In a 10-year time, we treated by DC 450 patients, 344 of whom underwent cranioplasty, either with autologous bone or artificial implants (hydroxyapatite, polyetheretherketone, titanium, polymethylmethacrylate)...

Degenerative spondylolisthesis is a common presentation, yet the best surgical treatment continues to be a matter of debate. Interbody fusion is one of a number of options, but its exact role remains ill defined. The aim of this study was to provide a contemporary review of the literature to help determine the role, if any, of interbody fusion in the surgical treatment of degenerative spondylolisthesis. A systematic review of the literature since 2005 was performed. Details on study size, patient age, surgical treatments, levels of slip, patient reported outcome measures, radiographic outcomes, complications and selected utility measures were recorded...

BACKGROUND: Secondary abdominal compartment syndrome is well known as a life-threatening complication in critically ill patients in an intensive care unit. Massive crystalloid fluid resuscitation has been identified as the most important risk factor. The time interval from hospital admittance to the development of manifest abdominal compartment syndrome is usually greater than 24 hours. In the absence of any direct abdominal trauma, we observed a rapidly evolving secondary abdominal compartment syndrome shortly after hospital admittance associated with massive transfusion of blood products and only moderate crystalloid resuscitation...

For nutritional support of critically ill patients, the enteral route is preferred over the parenteral route. Although nasojejunal feeding can be superior to gastric feeding when gastrointestinal symptoms occur, it does not necessarily solve the problem of large gastric residual volumes. We report the successful use of a newly developed nasojejunal feeding tube with gastric decompression function in an 84-year-old man with severe pneumonia. After gastric feeding was considered not well tolerated, the use of this tube improved the delivery of nutrition until the patient was stable enough to undergo percutaneous endoscopic gastrostomy...

INTRODUCTION: Supersonic, high altitude aviation places its pilots and aircrew in complex environments, which may lead to injury that is not easily diagnosed or simply treated. Decompression illness (either venous or arterial) and environmental conditions (e.g., abnormal gases and pressure) are the most likely adverse effects aircrew often face. Though symptomatic aircrew personnel may occasionally require hyperbaric oxygen treatment, it is rare to require more than one treatment before returning to baseline function...

The pulmonary interstitial emphysema (PIE) is a life-threatening illness in premature infants with mechanical ventilation. While most are managed conservatively, decompression would be necessary. Here, we report the first case of PIE treated by percutaneous catheter insertion in an extremely low birth weight (ELBW) infant in Korea. The patient, born with 660 g in 23+2 weeks of gestation, showed PIE in left lower lung on postnatal day 12. Percutaneous catheter insertion was performed on postnatal day 25. The size of PIE decreased, but didn't disappear completely...

"Yo-yo" diving may place divers at a greater risk of neurologic decompression illness (DCI). Using a rat model, we previously demonstrated that "yo-yo" diving has a protective effect against DCI. In the current study, we evaluated the risk of neurologic DCI following "yo-yo" dives in a pig model. Pigs were divided into four groups. The Control group (A) made a square dive, without excursions to the surface ("peeps"). Group B performed 2 "peeps", Group C performed 4 "peeps", and Group D did not dive at all. All dives were conducted on air to 5 atmospheres absolute, for 30 min bottom time...
