Patient positioning is a crucial step in neurosurgical interventions This is the responsibility of both the neurosurgeon and the anesthesiologist. Patient safety, surgeon’s comfort, choosing an optimal trajectory to the lesion, reducing brain tension by facilitating venous drainage, using gravitation to maintain the lesion exposed and dynamic retraction represent general rules for correct positioning. All bony prominences must be protected by silicone padding. The head can be positioned using a horseshoe headrest or three pin skull clamp, following the general principles: avoiding elevating the head above heart more than 30 degrees, avoiding turning the head to one side more than 30 degrees and maintaining 2 to 3 finger breaths between chin and sternum. Serious complications can occur if the patient is not properly positioned so this is why great care must be paid during this step of the surgical act.
Giant cell arteritis is a systemic inflammatory vasculitis, typically involving the superficial temporal arteries, but with possible ischemic and hemorrhagic cerebrovascular complications.
The case is reported of a patient with a clinical picture of giant cell arteritis, who had multiple occupational exposures to various infectious agents.
His initial favourable progress was followed by an atypical outcome. Despite immunosuppressive treatment, he developed fatal subarachnoid and intracerebral haemorrhages, possibly due to rupture of a microaneurysm of the posterior cerebral artery.
There are rare reports of the occurrence of acute transverse myelitis and Guillain–Barré syndrome after various surgical procedures and general/epidural anaesthesia. The concomitant occurrence of these pathologies is very rare and is called Guillain–Barré and acute transverse myelitis overlap syndrome. In this article, we present the case of a second trimester pregnant patient who developed Guillain–Barré and acute transverse myelitis overlap syndrome.
We report the case of a 16-year-old female patient who underwent a therapeutic termination of pregnancy two weeks prior to the onset of the disease with gradual development of a motor deficit with walking and sensitivity disorders, fecal incontinence. The diagnosis was based on clinical exam, electroneurography and spinal magnetic resonance imaging. Endocrinopathies, infectious diseases, autoimmune and inflammatory diseases, neoplastic diseases and vitamin deficiencies were ruled out. Our patient attended five sessions of therapeutic plasma exchange, followed by steroid treatment, intravenous immunoglobulin with minimum recovery of the motor deficit in the upper limbs, but without significant evolution of the motor deficit in the lower limbs. The patient was discharged on maintenance corticotherapy and immunosuppressive treatment with azathioprine.
We report a very rare association between Guillain–Barré syndrome and acute transverse myelitis triggered by a surgical intervention with general anaesthesia. The overlap of Guillain–Barré syndrome and acute transverse myelitis makes the prognosis for recovery worse, and further studies are needed to establish the first-line therapy in these cases.
Cardiovascular autonomic neuropathy is the most frequent clinical form of autonomous diabetic neuropathy and appears secondary to cardiac autonomous fibre involvement, actively involved in cardiac rhythm impairment. Type 2 diabetes mellitus patients can present cardiac autonomic neuropathy early in the disease. Autonomous nerve function in DM patients should be assessed as early as the diagnosis is set in order to establish the optimal therapeutic strategy. The most frequent cardio-vagal test used is heart rate variability. An abnormal heart rate variability in the presence of orthostatic arterial hypotension indicates a severe cardiac autonomic neuropathy diagnosis. The development of cardiac autonomic neuropathy is subjected to glycaemic control, duration of the disease and associated risk factors. The glycaemic control is extremely important, especially early in the disease. Therefore, a poor glycaemic control carries unfavourable long-term effects, despite an ulterior optimal control, a phenomenon named “hyperglycaemic memory”. In type 2 diabetes mellitus patients, the association of cardiac autonomic neuropathy with intensive glycaemic control increases the mortality rate, due to the fact, that, secondary to autonomous impairment, the patients do not present the typical symptoms associated with hypoglycaemia. Stratifying the cardiac autonomic neuropathy aids the clinician in assessing the morbidity and mortality risk of diabetes mellitus patients, because it is an independent risk factor for mortality, associated with silent myocardial infarctions and the risk of sudden death.
The clinical manifestations of Lyme disease are protean. The meningoradiculitis is a common and well-recognized complication of neuroborreliosis but can be easily misdiagnosed without a high degree of clinical suspicion, mainly if the tick bite is not present in the medical history. We report two cases of Lyme meningoradiculitis with excellent outcome after appropriate antibiotic therapy. In an endemic area in case of neurological manifestations suggestive for neuroborreliosis the serological testing for B. burgdorferi in serum and cerebrospinal fluid is imperative for the correct diagnosis.
