Data on the socioeconomic burden of chronic headache (≥15 days/last month or 180 days/year) is lacking. This study investigated the impact of chronic headache on sickness absence, unemployment and disutility in the general population in Norway.

Trigeminal neuralgia is caused by compression of trigeminal nerve root and it leads to demyelination gradually. It was almost idiopathic and occurred unexpected. The upper cervical spinal cord contains the spinal trigeminal tract and nucleus. Fibers with cell bodies in the trigeminal ganglion enter in the upper pons and descend caudally to C2 level. We experienced a rare patient with facial pain, which was paroxysmal attack with severe pain after a clear event, cervical spinal injury (C2). So, this case reminds us of a possible cause of trigeminal neuralgia after a trauma of the head and neck.

Pregnancy complicated by ankylosing spondylitis is rare. Labor assistance and instrumental delivery may be difficult due to hip stiffness. Restriction in lumbar flexion may cause difficulties in administering neuraxial analgesia. Difficult intubation for general anesthesia due to limited neck mobility is another potential risk that must be considered.

Endometriomas are a unique and complex representation of the classic phenotypes of endometriosis. Associated symptoms, high recurrence rate, and multimodal approach represent ongoing challenges in the management of this chronic disease.

Hypertrophic pachymeningitis (HP) is a chronic, progressive diffuse inflammatory condition that leads to thickening of the dura mater and can be idiopathic or associated with sarcoidosis among other disorders. In this case report, we present a rare case of cervical spine HP in a 29-year-old woman in the post-partum period, who had a history of pituitary adenoma and juvenile rheumatoid arthritis. Magnetic resonance imaging (MRI) of the spine revealed a soft tissue mass and moderate cord compression. The patient underwent C3-C7 laminectomy. Pathological analysis of the cervical epidural mass demonstrated a reactive inflammatory cell process. Recurrence of symptoms and worsening of pachymeningitis on imaging studies warranted further work-up which revealed mediastinal/hilar lymphadenopathy. Transbronchial biopsy revealed non-caseating granulomatous disease consistent with sarcoidosis. The patient was started on oral steroids and eventually methotrexate with significant clinical and radiographic improvement. Follow-up imaging studies showed minimal dural thickening in the thoracic spine and eventually complete resolution. HP should be considered in a patient with spinal cord compression, myelopathy, and radicular pain of unclear etiology, and sarcoidosis should be considered in idiopathic cases.

Subarachnoid hemorrhage (SAH) usually occurs due to aneurysmal rupture of intracranial arteries and its typical computed tomography (CT) findings are increased attenuation of cisterns and subarachnoid spaces. However, several CT findings mimicking SAH are feasible in diverse conditions. They are so-called as pseudo-SAH, and this report is a case of pseudo-SAH which is misdiagnosed as aneurysm rupture accompanied by bilateral chronic subdural hematoma (cSDH). A 42-year-old male with severe headache visited our institute. Non-contrast brain CT images showed increased attenuation on basal cistern, and cSDH on both fronto-temporo-parietal convexity with midline shifting. Trans-femoral cerebral angiography was done and we confirmed small aneurysm at right M1 portion of middle cerebral artery. Under diagnosis of SAH, we planned an operation in order to clip aneurysmal neck and remove cSDH. cSDH was removed as planned, however, there was no SAH and we also couldn't find the rupture point of aneurysm. Serial follow-up CT showed mild cumulative cSDH recurrence, but the patient was tolerant and had no neurologic deficit during hospitalization. We have checked the patient via out-patient department for 6 months, there are no significant changes in volume and density of cSDH and the patient also have no neurologic complications.

Postoperative infections after spinal surgery are a challenging issue, difficult to diagnose and treat, that requires prolonged medical therapy and even surgery. In this paper, we aim to review the current standards in the diagnosis and treatment of post-procedural Spondylodiscitis (SD). We performed a review of the available literature focusing on diagnostic and therapeutic standards of post-procedural SD, both after minimally invasive procedures and open surgery. Spinal infections can occur in less invasive procedures with an incidence ranging from 0.26% to 2.75%. Post-surgical spinal infections range from 2.1% to 8.5% for instrumented surgery, whereas these are less than 1% in open surgery without instrumentation. MRI is currently the most sensitive and specific technique to diagnose postoperative SD. CT guided aspiration culture should be performed in all patients with deep-seated infections with negative blood cultures. Early infections start with wound healing problems within a few weeks from surgery, and the occurrence of fever and an increase in serum markers of inflammation. Late infections often cause chronic pain, implant failure, non-union or wound dehiscence even a long time after surgery. The onset of the infection differentiates the specific treatment. Indeed, in the early postoperative period spinal fusion is not appropriate yet, and the stability of the fusion site only relies on the instrumentation. Therefore, even when suitable, implant removal may lead to undesirable consequences. In chronic infections, on the other hand, implant removal is unlikely to determine instability since the fusion has already been accomplished.

An adequate anesthesia technique generates appropriate postoperative analgesic properties and decreases the patient's stress response. This will lead to decreased morbidity and mortality associated with immunology disturbances, such as infection, prolonged wound healing, and sepsis.

Approximately 60 % of patients with acute iliofemoral deep vein thrombosis recover without further symptoms. However, 40 % will have some degree of post-thrombotic syndrome (PTS) and 4 % will develop severe PTS. PTS is the most common complication; it reduces quality of life and increases DVT-related costs. The clinical symptoms and severity of PTS may vary; the most common symptoms include edema, pain, hyperpigmentation, lipodermatosclerosis, and ulceration. PTS is based on the principle of outflow obstruction, may be caused by venous hypertension, and may lead to valvular damage and venous reflux or insufficiency. A significant lumen reduction within the iliac vein system is defined by an aspect ratio ≥ 2. Recent technical developments and new dedicated venous stent techniques now give the opportunity to recanalize even complex venous outflow obstructions. First in man safety and efficacy data are very promising for the new dedicated venous stents, but long-term data are still missing.

Optimal pain control post-pancreatoduodenectomy is a challenge. Epidural analgesia (EDA) is increasingly utilized despite inherent risks and unclear effects on outcomes.
