Severe and Symptomatic Calcium Disorders Caused by Secondary Bone Disease in a Patient with a Thyroid Storm

A patient with Graves’ disease was admitted with a thyroid storm. She had severe hypercalcaemia caused by thyrotoxicosis. Treatment was complicated by vomiting and diarrhoea. With intravenous ondansetron, hydration and bisphosphonates, GI symptoms improved and oral thyreostatics could be started. This, combined with bisphosphonate administration, resulted in a mild hungry bone syndrome.

Embolisation of Vertebral Artery Damaged Following Cervical Disc Removal

Introduction: The incidence of vertebral artery (VA) injury during cervical spine surgery is rare. Even though tamponade is effective in many cases, early consultation of an endovascular team is recommended if bleeding cannot be controlled. We report a case of emergent endovascular embolisation of left VA due to iatrogenic injury during anterior cervical disc removal and fusion. Case: A 47-year-old woman was admitted to our emergency department with serious arterial bleeding from the neck only hours after undergoing anterior cervical disc removal and fusion surgery. She was intubated and mechanically ventilated, however hemorrhage could not be successfully controlled by packing with surgical hemostatic agents. Cranial computed tomography, computed tomography of the cervical spine and CT angiography confirmed the suspected diagnosis of injury to the VA. Emergent endovascular embolisation successfully stopped the bleeding. Occlusion of the vessel was achieved by vascular plugging. The patient was discharged from our hospital 14 days after the intervention, receiving a revision surgery of the cervical spine on the day of embolisation. At the date of discharge she presented without any focal neurological deficit. Conclusion: Pre-operative radiographic imaging of the cervical spine should be used routinely to identify anatomic abnormalities of the vertebral arteries. Endovascular embolisation appears to be effective in treating acute iatrogenic dissection of the vertebral arteries.

Potential Arctic tundra vegetation shifts in response to changing temperature, precipitation and permafrost thaw

Over the past decades, vegetation and climate have changed significantly in the Arctic. Deciduous shrub cover is often assumed to expand in tundra landscapes, but more frequent abrupt permafrost thaw resulting in formation of thaw ponds could lead to vegetation shifts towards graminoid-dominated wetland. Which factors drive vegetation changes in the tundra ecosystem are still not sufficiently clear. In this study, the dynamic tundra vegetation model, NUCOM-tundra (NUtrient and COMpetition), was used to evaluate the consequences of climate change scenarios of warming and increasing precipitation for future tundra vegetation change. The model includes three plant functional types (moss, graminoids and shrubs), carbon and nitrogen cycling, water and permafrost dynamics and a simple thaw pond module. Climate scenario simulations were performed for 16 combinations of temperature and precipitation increases in five vegetation types representing a gradient from dry shrub-dominated to moist mixed and wet graminoid-dominated sites. Vegetation composition dynamics in currently mixed vegetation sites were dependent on both temperature and precipitation changes, with warming favouring shrub dominance and increased precipitation favouring graminoid abundance. Climate change simulations based on greenhouse gas emission scenarios in which temperature and precipitation increases were combined showed increases in biomass of both graminoids and shrubs, with graminoids increasing in abundance. The simulations suggest that shrub growth can be limited by very wet soil conditions and low nutrient supply, whereas graminoids have the advantage of being able to grow in a wide range of soil moisture conditions and have access to nutrients in deeper soil layers. Abrupt permafrost thaw initiating thaw pond formation led to complete domination of graminoids. However, due to increased drainage, shrubs could profit from such changes in adjacent areas. Both climate and thaw pond formation simulations suggest that a wetter tundra can be responsible for local shrub decline instead of shrub expansion.
