BACKGROUND: About 5-15% of people in the Western world will suffer from an extended period of tinnitus during their lifetime. This is often a non-treatable, disabling disorder. Tinnitus can be classified as pulsatile or non-pulsatile. Pulsatile tinnitus can be caused by a treatable neurovascular compression. CASE DESCRIPTION: Here we describe two patients, a 68-year old woman and 40-year old man suffering from pulsatile tinnitus and hemifacial spams due to neurovascular compression of the facial and acoustic nerve in the anterior cranial fossa...

Jannetta S Steyn, Peter Andras
The temporal relationship between the activities of neurons in biological neural systems is critically important for the correct delivery of the functionality of these systems. Fine measurement of temporal relationships of neural activities using micro-electrodes is possible but this approach is very limited due to spatial constraints in the context of physiologically valid settings of neural systems. Optical imaging with voltage-sensitive dyes or calcium dyes can provide data about the activity patterns of many neurons in physiologically valid settings, but the data is relatively noisy...

The comparative genomics between different rhodopsin-like family groups (α, β, γ and δ) is not well studied. We used a combination of phylogenetic analysis and statistical genomic methods to compare rhodopsin-like family proteins in species likely symbolic of this family's evolutionary progression. For intra-cluster relationships, we applied mathematical optimisation to enhance the tree search produced by the neighbour joining method (NJ) and compared it with maximum likelihood (ML) method. To infer inter-clusters relationships, we used Needleman-Wunsch analysis (NW), HHsearch, ancestral sequence reconstruction and phylogenetic network analysis...

BACKGROUND: Microvascular decompression (MVD) represents the most effective and safe surgical option for the treatment of trigeminal neuralgia since it was first popularized by Jannetta 50 years ago. Despite several advances have been proposed, the rate of complications as cerebellar and vascular injury, hearing loss, muscular atrophy, cerebrospinal fluid (CSF) leak, postoperative cutaneous pain and sensory disturbances, remain still actual and may negatively affect the outcome. We propose some technical nuances of the surgical procedure we used in our recent series...

The use of a Teflon implant for Jannetta surgery in patients with trigeminal neuralgia is complicated in rare cases by the development of a Teflon granuloma and can cause recurrent facial pain. The article presents a clinical case of a Teflon granuloma developed after microvascular decompression of the trigeminal nerve root, describes the surgical findings and histological picture, and analyzes the literature, causes of granuloma development, and recommendations for treatment of these patients.

PURPOSE: Arthrodesis (AD) of the knee reduces pain and provides stability, but has severe functional and social limitations. There has been ample discussion on the value of a conversion of an AD to a total knee arthroplasty (TKA). The aim of this study was to perform a review and meta-analysis of the current literature on conversion of an AD to TKA and assess clinical outcome, complication rate, surgical technique and overall patient-related outcome measures. METHODS: PubMed, Embase, Web of Science, Cochrane, CENTRAL, CINAHL, Academic Search Premier, ScienceDirect and searching by hand for papers on conversion of AD of the knee to TKA...

In platelets, splicing and translation occur in the absence of a nucleus. However, the integrity and stability of mRNAs derived from megakaryocyte progenitor cells remain poorly quantified on a transcriptome-wide level. As circular RNAs (circRNAs) are resistant to degradation by exonucleases, their abundance relative to linear RNAs can be used as a surrogate marker for mRNA stability in the absence of transcription. Here we show that circRNAs are enriched in human platelets 17- to 188-fold relative to nucleated tissues and 14- to 26-fold relative to samples digested with RNAse R to selectively remove linear RNA...

BACKGROUND: Comprehensive biotic surveys, or 'all taxon biodiversity inventories' (ATBI), have traditionally been limited in scale or scope due to the complications surrounding specimen sorting and species identification. To circumvent these issues, several ATBI projects have successfully integrated DNA barcoding into their identification procedures and witnessed acceleration in their surveys and subsequent increase in project scope and scale. The Biodiversity Institute of Ontario partnered with the rare Charitable Research Reserve and delegates of the 6th International Barcode of Life Conference to complete its own rapid, barcode-assisted ATBI of an established land trust in Cambridge, Ontario, Canada...

OBJECT: In spite of solid anatomical and physiological arguments and the promising results of Jannetta in the 1970s, treating essential hypertension by microvascular decompression (MVD) of the brainstem has not gained acceptance as a mainstream technique. The main reason has been a lack of established selection criteria. Because of this, the authors' attempts have been limited to patients referred for MVD for hemifacial spasm (HFS) who also had hypertension likely to be related to neurovascular compression (NVC)...

BACKGROUND: Traumatic events such as disasters, accidents, war, or criminal violence are often accompanied by the loss of loved ones, and may then give rise to traumatic grief. Traumatic grief refers to a clinical diagnosis of persistent complex bereavement disorder (PCBD) with comorbid (symptoms of) posttraumatic stress disorder (PTSD) and/or major depressive disorder (MDD) following confrontation with a traumatic loss. Trauma survivors, who are frequently from different cultural backgrounds, have often experienced multiple losses and ambiguous loss (missing family members or friends)...

Many hyperplasias and lymphomas of marginal zone B-cells are associated with infection. We identified six children and one adolescent with cervical lymphadenopathy showing prominent polyclonal nodal marginal zone hyperplasia (pNMZH) and four adolescents with monoclonal paediatric nodal marginal zone lymphoma (pNMZL). The clonality status was assessed using BIOMED-2-IG PCR analysis. Haemophilus influenzae was identified in all six cases of pNMZH that could be tested by direct culture (N = 3) or a very sensitive PCR for the H...

Hemifacial spasm (HFS) is a facial movement disorder characterized by involuntary, unilateral and intermittent contractions of the facial muscles. It is one of the syndromes related to neurovascular conflict, first described by Jannetta et al. in 1979. Typically, HFS is due to pulsatile compression by the anterior inferior cerebellar artery. We describe a rare case of left developmental venous anomaly in a 59-year-old man referred to us with a six-month history of left-sided HFS. We performed an MR study of the brain and cerebellopontine angles, which demonstrated a compression of the ipsilateral facial nerve by the developmental venous anomaly...

OBJECTIVE: Ceramics are widely used materials for prosthesis, especially in dental fields. Despite multiple biomedical applications, little is known about ceramic surface modifications and the resulting cell behavior at its contact. The aim of this study is to evaluate the biological response of polished versus glazed surface treatments on lithium disilicate dental ceramic. METHODS: We studied a lithium disilicate ceramic (IPS e.max(®) Press, Ivoclar Vivadent) with 3 different surface treatments: raw surface treatment, hand polished surface treatment, and glazed surface treatment (control samples are Thermanox(®), Nunc)...

Ser-64, an autophosphorylation site in the autoinhibitory subdomain of cGMP-dependent protein kinase type I-alpha (PKGI-alpha), lowers affinity for cGMP and suppresses catalytic activity (1). Using the structure of homologous cAMP-dependent protein kinase as a model, three conserved residues (Gln-401, His-404, Cys-518) in the PKGI-alpha catalytic site are predicted to be juxtaposed to Ser-64 (2). Individual point mutants (Q401A, H404A and C518A) and a double mutant (S64A/H404A) have been generated. cGMP or cAMP affinities (K(a)) of each mutant protein for phosphotransferase activation and allosteric (3H)cGMP-binding affinity (K(D)) of each mutant protein are significantly improved over those of wild-type (WT) PKGI-alpha...

We report the case of a 39-year-old female patient who suffered from trigeminal neuralgia of the left lingual nerve for 6 years. The previous therapy according to the guidelines including a Jannetta operation was unsuccessful. Only after beginning with daily mastication and consumption of very hot chilli peppers has the patient become reliably pain-free.

Idiopathic trigeminal neuralgia is defined as brief paroxysms of pain limited to the facial distribution of the trigeminal nerve. Drug therapy is considered to be the first-line of treatment for trigeminal neuralgia. Unfortunately, medical treatment does not always provide satisfactory pain relief for 25% of the patients. Moreover, the relief provided by drug therapy generally decreases over time, and increased dosages of these medications are limited because of side effects. In this case, patients can be offered several surgical approaches, such as percutaneous techniques (thermocoagulation, microcompression, glycerol injection) or microvascular decompression in the cerebello-pontine angle (Gardner-Jannetta's technique)...

Parkinson's disease affects over one million people in the United States. Although there have been remarkable advances in uncovering the pathogenesis of this disabling disorder, the etiology is speculative. Medical treatment and operative procedures provide symptomatic relief only. Compression of the cerebral peduncle of the midbrain by the posterior cerebral artery in a patient with Parkinson's Disease (Parkinson's Disease) was noted on magnetic resonance imaging (MRI) scan and at operation in a patient with trigeminal neuralgia...

BACKGROUND: Insulin resistance (hyperinsulinemia) is said to be the signal event and causal in the development of type 2 diabetes mellitus. Pulsatile arterial compression of the right anterolateral medulla oblongata is associated with autonomic dysfunction, including "driving" the pancreas, which increases insulin resistance causing type 2 diabetes mellitus. In this prospective study, we hypothesize that decompressing the right cranial nerve X and medulla will result in better glycemic control in patients with type 2 diabetes mellitus...
