The aim of this retrospective analysis was to examine olfactory disorders among the patients in the Ear, Nose, and Throat Clinic of Tampere University Hospital, Finland, from 2001 to 2011, and to evaluate the necessity of imaging in the examination of patients with olfactory disorders. Charts of 143 consecutive patients with a primary olfactory disorder were examined, and 69 patients who had undergone the necessary testing were included in the study. The most common causes of olfactory disorder were upper respiratory infection (23%), chronic rhinosinusitis (19%), head trauma (17%), and allergic or nonallergic rhinitis (6%)...

Background Hereditary angioedema with C1 inhibitor deficiency is characterized by recurrent, unpredictable swelling episodes caused by uncontrolled plasma kallikrein generation and excessive bradykinin release resulting from cleavage of high-molecular-weight kininogen. Lanadelumab (DX-2930) is a new kallikrein inhibitor with the potential for prophylactic treatment of hereditary angioedema with C1 inhibitor deficiency. Methods We conducted a phase 1b, multicenter, double-blind, placebo-controlled, multiple-ascending-dose trial...

Lomerizine, calcium channel blocker, is the most used medication for migraine prophylaxis in Japan. The effectiveness of this drug is reported as 50-75%. Telmisartan is angiotensin II receptor blockers which plasma half-life is 24 h. We examined whether telmisartan has preventative benefits in lomerizine non-responsive migraineurs. Lomerizine non-responders received telmisartan (20 mg/day) for 3 months after the investigation period of 3 months. Blood pressure, frequency of headache days/month, headache severity, and doses of triptans and analgesics were analyzed by Wilcoxon signed rank test...

REVIEW
Kamran Habib Awan
Botulinum toxin (Botox) is an exotoxin produced from Clostridium botulinum. It blocks the release of acetylcholine from the cholinergic nerve end plates resulting in inactivity of the muscles or glands innervated. The efficacy of Botox in facial aesthetics is well established; however, recent literature has highlighted its utilization in multiple non-cosmetic medical and surgical conditions. The present article reviews the current evidence pertaining to Botox use in the non-cosmetic head and neck conditions...

Migraine is characterized by severe headaches that can be preceded by an aura likely caused by cortical spreading depression (SD). The antiepileptic pregabalin (Lyrica) shows clinical promise for migraine therapy, although its efficacy and mechanism of action are unclear. As detected by diffusion-weighted MRI (DW-MRI) in wild-type (WT) mice, the acute systemic administration of pregabalin increased the threshold for SD initiation in vivo. In familial hemiplegic migraine type 1 mutant mice expressing human mutations (R192Q and S218L) in the CaV2...

The Ehlers-Danlos syndromes (EDS) are a heterogeneous group of heritable connective tissue disorders characterized by joint hypermobility, skin extensibility, and tissue fragility. This communication briefly reports upon the neurological manifestations that arise including the weakness of the ligaments of the craniocervical junction and spine, early disc degeneration, and the weakness of the epineurium and perineurium surrounding peripheral nerves. Entrapment, deformation, and biophysical deformative stresses exerted upon the nervous system may alter gene expression, neuronal function and phenotypic expression...

BACKGROUND: Skull base osteomyelitis is an uncommon disease that usually complicates a malignant external otitis with temporal bone involvement. It affects predominantly diabetic and immunocompromised males and has a high mortality rate. Pseudomonas aeruginosa is the most common causative organism. Currently, there is no consensus about the best therapeutic option. Here we describe a case of severe skull base osteomyelitis caused by Pseudomonas aeruginosa with progressive palsy of cranial nerves that was successfully managed with prolonged outpatient continuous infusion of ceftazidime plus oral ciprofloxacin...

Clara Haskil (January 7, 1895-December 7, 1960) was one of the most famous female pianists of the 20th century. In her life and work she set new standards in piano playing. However, her career was beset by poor health and the adversities of two world wars. In her lifetime Haskil had three major disorders: juvenile scoliosis requiring treatment in her adolescence, a tumor of the sellar region requiring surgery at age 47 years, and a traumatic brain injury causing her death at the age of 65. Her medical history illustrates the development of surgical methods and rehabilitation in medicine before and after World War II...

OBJECTIVE: Temporomandibular disorder (TMD) is a variety of clinical problems that originate from the area of the temporomandibular joint (TMJ), masticatory muscles, and surrounding tissues. There are different treatment options; however, there is no evidence that low level laser treatment (LLLT) will last about six months. The aim of this study was to determine the survival rate of treatment with red (660 nm) and infrared (790 nm) laser in cases of TMDs. METHODS: In 19 subjects, one side of the face (half face) was randomly selected to receive intervention, in a total of 116 sensitive points...

BACKGROUND: Aneurysmal subarachnoid hemorrhage (SAH) accounts for 5% of strokes and carries a poor prognosis. It affects around 6 cases per 100,000 patient years occurring at a relatively young age. METHODS: Common risk factors are the same as for stroke, and only in a minority of the cases, genetic factors can be found. The overall mortality ranges from 32% to 67%, with 10-20% of patients with long-term dependence due to brain damage. An explosive headache is the most common reported symptom, although a wide spectrum of clinical disturbances can be the presenting symptoms...

BACKGROUND: Current standard of care for trigeminal neuralgia is treatment with the sodium channel blockers carbamazepine and oxcarbazepine, which although effective are associated with poor tolerability and the need for titration. BIIB074, a Nav1.7-selective, state-dependent sodium-channel blocker, can be administered at therapeutic doses without titration, and has shown good tolerability in healthy individuals in phase 1 studies. We therefore assessed the safety and efficacy of BIIB074 in patients with trigeminal neuralgia in a phase 2a study...

BACKGROUND: Sentinel headache is a well-known warning sign preceding subarachnoid hemorrhage (SAH) due to rupture of an intracranial aneurysm. New-onset seizure or "sentinel seizure" preceding aneurysmal SAH, however, is uncommon. CASE DESCRIPTION: We report on a 51-year-old man who presented with a new-onset seizure. Diagnostic work-up revealed a giant middle cerebral artery aneurysm without evidence of subarachnoid or intracerebral hemorrhage. Anti-epileptic therapy was initiated, elective diagnostic angiography and subsequent treatment was scheduled and the patient discharged home...

INTRODUCTION: Eslicarbazepine acetate (ESL), together with carbamazepine and oxcarbazepine, belongs to the dibenzazepine family. According to the latest clinical practice guidelines, tricyclic antidepressants, dual antidepressants (venlafaxine, duloxetine), and some antiepileptics (gabapentin, pregabalin) are first-line drugs for neuropathic pain; tramadol, lidocaine 5% patches, and capsaicin 8% patches are considered second-line drugs; and strong opioids constitute a third line of treatment...
