BACKGROUND: The complexity of the frontal sinus drainage pathway (FSDP) can be challenging even for expert surgeons. Several classifications have been proposed to simplify the understanding of FSDP, whose anatomical variability can be simplified based on the knowledge of its developmental mechanisms. METHODS: Cone-beam computed tomography studies performed at the Unit of Radiology of the University of Brescia between March and November 2012 were retrospectively analyzed...

BACKGROUND: The prevalence of obesity is increasing worldwide, and the economic consequences of an increased percentage of obese workers are relevant in terms of health costs and absences from work. Obesity is associated with reduced participation in the workforce, increased absence from work, disability and health costs, lower salaries and reduced productivity. OBJECTIVES: We aimed at quantifying the limitations in range of motion (ROM) of the upper limb and the trunk of obese workers during basic occupational tasks...

OBJECTIVES: The aim of this study was to better understand the usual learning curve in acquiring endonasal endoscopic sinus and skull base surgery (ESSBS) techniques during the novice training on the lamb's head model. METHODS: Ten novices were asked to perform 10 bilateral dissections on the particular lamb's head each. The dissections were uniform, consisted of 10 well-defined steps, beginning from the simple removal of the inferior turbinate, and ending with more complicated procedures like cerebrospinal fluid leak repair, Draf 3 procedure for the frontal sinus and elevation of the nasal septal flap...

The medial prefrontal cortex (mPFC) coordinates goal-directed behaviors, which may be mediated through mPFC regulation of dopamine release in the nucleus accumbens (NAc). Furthermore, frequency-specific oscillatory activity between the frontal cortex and downstream structures may facilitate inter-region communication. Although high-frequency (e.g., 60 Hz) mPFC stimulation is known to increase basal dopamine levels in the NAc, little is known about how phasic dopamine release is affected by mPFC stimulation...

Research with young adults has shown hand proximity biases attention both early (by the time stimuli are categorized as relevant for action) and later, selectively for goal-relevant-stimuli. We examined age-related changes in this multisensory integration of vision and proprioception by comparing behavior and event-related potentials (ERPs) between younger and older adults. In a visual detection task, the hand was placed near or kept far from target and nontarget stimuli matched for frequency and visual features...

OBJECTIVE: The ability to flexibly switch between tasks is considered an important component of cognitive control that involves frontal and parietal cortical areas. The present study was designed to characterize network dynamics across multiple brain regions during task switching. METHOD: Functional magnetic resonance images (fMRI) were captured during a standard rule-switching task to identify switching-related brain regions. Multiregional psychophysiological interaction (PPI) analysis was used to examine effective connectivity between these regions...

The frontal cortex is heavily involved in oculomotor selection. Here, we investigated the neural correlates of eye movement selection during an antisaccade task in a young epileptic patient in whom the seizure focus included the frontal cortex and affected its function. Before resection surgery, the patient had difficulty in performing correct antisaccades towards the visual field contralateral to the seizure focus. Because the FEF is the only area in the human frontal cortex that is known to have a lateralized oculomotor function in the antisaccade task, this behavioural imbalance between the two visual fields suggests a disruption of FEF functioning by the nearby seizure focus...

We carried out a comparative morphometric analysis of 56 species of salamandrid salamanders, representing 19 out of 21 extant genera, with the aim of uncovering the major patterns of skull shape diversification, and revealing possible trends and directions of evolutionary change. To do this we used micro-computed tomography scanning and three-dimensional geometric morphometrics, along with a well-resolved molecular phylogeny. We found that allometry explains a relatively small amount of shape variation across taxa...

BACKGROUND: Although the study of the neuroanatomical correlates of generalized anxiety disorder (GAD) is gaining increasing interest, up to now the cortical anatomy of GAD patients has been poorly investigated and still no data on cortical gyrification are available. The aim of the present study is to quantitatively examine the cortical morphology in patients with GAD compared with healthy controls (HC) using magnetic resonance imaging (MRI). To the best of our knowledge, this is the first study analyzing the gyrification patterns in GAD...

Background: The presence of pain during movement typically results in changes in technique. However, the physical properties of water, such as flotation, means that water-based exercise may not only reduce compensatory movement patterns but also allow pain sufferers to complete exercises that they are unable to perform on land. The purpose of this study was to assess bilateral kinematics during double-leg squats and single-leg squats on land and in water in individuals with unilateral anterior knee pain...

It has recently been reported that repetitive transcranial magnetic stimulation combined with motor training (rTMS-MT) could improve motor function in post-stroke patients. However, the effects of rTMS-MT on cortical function using functional connectivity and graph theoretical analysis remain unclear. Ten healthy subjects were recruited to receive rTMS immediately before application of MT. Low frequency rTMS was delivered to the dominant hemisphere and non-dominant hand performed MT over 14 days. The reaction time of Nine-Hole Peg Test and electroencephalography (EEG) in resting condition with eyes closed were recorded before and after rTMS-MT...

An 82-year-old man was admitted to the emergency department following bizarre behaviour. Police had noticed him driving erratically through his village. He did not stop when instructed, drove slowly home and appeared 'vacant' on questioning. While in hospital, he had approximately 15 episodes of catatonia, involving rigidity, negativism, mutism except echolalia and perseveration, automatic obedience and utilisation phenomena, lasting 2-20 min each. Between episodes, he was amnestic but otherwise well. Electroencephalography demonstrated bifrontal slowing with left-sided emphasis, and captured two focal onset partial seizures with the clinical correlate of the syndrome described above...

Gaucher's disease is a rare autosomal recessive, potentially fatal disorder but most common type among lysosomal storage disorders. The disease's incidence is around 1/40 000 to 1/60 000 births in the general population. A 32-year-old man, born out of non-consanguineous union, presented with generalised tonic-clonic seizures and myoclonus since 17 years of age. Seizures were noted to be resistant to multiple epileptic drugs. He developed gait imbalance, intentional tremor and dysarthria. Detailed examination revealed hepatosplenomegaly, bilateral pancerebellar signs with normal power, reflexes and sensory system...

BACKGROUND: Androgenetic alopecia (AGA) seems to be a marker of increased risk of prostate cancer (PCa). OBJECTIVE: We sought to investigate potential pathophysiological differences between frontal and vertex balding that might have the impact on the incidence of PCa. METHODS: Serum concentrations of testosterone (T), dihydrotestosterone (DHT) and prostate-specific antigen (PSA) were measured in 88 subjects with AGA. RESULTS: We have examined sixty patients with frontal baldness and 28 patients with vertex baldness...

Background: The longitudinal association between cerebral amyloid-beta (Aβ) and change in gait, and whether this association is mediated by cortical thickness, has yet to be determined. Methods: We included 439 clinically normal (CN) participants, aged 50-69 years and enrolled in the Mayo Clinic Study of Aging with cerebral Aβ, cortical thickness, and gait measurements. Cerebral Aβ deposition was assessed by Pittsburgh Compound B (PiB)-PET in multiple regions of interest (ROIs) (i...

While aging is associated with increased knowledge, it is also associated with decreased semantic integration. To investigate brain activation changes during semantic integration, a sample of forty-eight 25-75 year-old adults read sentences with high cloze (HC) and low cloze (LC) probability while functional magnetic resonance imaging was conducted. Significant age-related reduction of cloze effect (LC vs. HC) was found in several regions, especially the left middle frontal gyrus (MFG) and right inferior frontal gyrus (IFG), which play an important role in semantic integration...

BACKGROUND: There is increasing evidence that psychotherapy can alter the function of the brain of patients with borderline personality disorder (BPD). However, it is not known whether psychotherapy can also modify the brain structure of patients with BPD. METHODS: We used structural MRI data of female patients with BPD before and after participation in 12 weeks of residential dialectical behavioural therapy (DBT) and compared them to data from female patients with BPD who received treatment as usual (TAU)...

Transitioning of rhinologic procedures from the operating room to the office setting in selected patients is a rising trend. An effective pain-control, patient-preparation protocol is essential, especially with advanced in-office rhinologic procedures such as hybrid balloon sinus dilation (BSD), in which other procedures such as ethmoidectomy, turbinate reduction, and other procedures are concomitantly performed. A regimen using oral sedation, topical tetracaine gel, topical tetracaine/epinephrine-soaked cottonoid packs, and intranasal local infiltrative anesthesia can vary significantly in effectiveness and be suboptimal at times (as determined by using treated patients as historical controls)...

Mucoceles of the paranasal sinus can be managed endoscopically with an extremely low recurrence rate. Frontal sinus mucoceles can sometimes be prevented from closing and reforming by stenting, which to the best of our knowledge has not yet been reported in the maxillary sinus. We describe the cases of 5 patients-3 men and 2 women, aged 47 to 75 years (mean: 59.6)-with a recurrent and intractable maxillary sinus mucocele that was managed with biliary T-tube stenting. The indications for stenting included recurrent episodes of mucocele with or without a lateral location with a relatively thick bony wall...

Literacy and numeracy equally affect an individual's success in and beyond schools, but these two competencies tend to be separately examined, particularly in neuroimaging studies. The current resting-state fMRI study examined the neural correlates of literacy and numeracy in the same sample of healthy adults. We first used an exploratory "Multivariate Distance Matrix Regression" (MDMR) approach to examine intrinsic functional connectivity (iFC), highlighting the middle frontal gyrus (MFG) for both competencies...
