Anal metastasis of colorectal cancer is very rare and is usually associated with a history of anal disease, including anal fistula, fissure, hemorrhoidectomy, and anastomotic injury. We report a case of rectal cancer with a synchronous anal metastasis consisting of adenocarcinoma of squamous cells without a history of anal disease. A 60-year-old woman had a chief complaint of melena. She had a 1.5-cm anal tumor on the perianal skin, and a Bollman type 2 rectal tumor on the Ra portion was found on colonoscopy...

Cerebrospinal fluid (CSF) pathway studies have revealed that the CSF secreted from the choroid plexus of the ventricles after egressing from the fourth ventricle reaches the basal suprasellar cistern and ultimately the sylvian cisterns. From the sylvian cistern, the CSF travels over the cerebral convexity subarachnoid space to reach the superior sagittal sinus and enters the bloodstream. Diverting CSF from the lateral ventricle with a shunt catheter to the sylvian cistern can be an option to treat obstructive hydrocephalus...

It is well known that the insular cortex (Brodmann areas 13, 14, 15, and 16) located deep inside the Sylvian fissure is associated with mental functions such as perception, language, cognition, affect, and movement. In particular, the insular cortex has been linked to interoception, which is the representation of bodily physiological states that is used to regulate bodily states and mental functions. Recently, a common principle to explain such functions of the insular cortex has been proposed. The principle posits that the anterior insula generates predictions of future bodily states, computes the error by comparing the prediction with the actual sensory signals, and integrates the body with the mind by minimizing the prediction error...

Empty azygos fissure implies dislocation of the azygos vein to the mediastinal side of the right upper lobe from azygos fissure, which is usually secondary to pneumothorax, pleural effusion, parenchymal fibrosis, vertebral collapse or persistent vomiting. We are presenting here a case where a separated azygos vein in CT and radiography images was noted. Moreover, in the follow-up images, it appeared that the complete reexpansion of the right lung resulted in reentrance of the azygos vein into azygos fissure in its native position...

INTRODUCTION: Interest in the function of the inferior parietal lobule (IPL) has resulted in increased understanding of its involvement in visuospatial and cognitive functioning, and its role in semantic networks. A basic understanding of the nuanced white-matter anatomy in this region may be useful in improving outcomes when operating in this region of the brain. We sought to derive the surgical relationship between the IPL and underlying major white-matter bundles by characterizing macroscopic connectivity...

The superior orbital fissure syndrome (SOFS) is a rare condition presenting as painful unilateral opthalmoplegia, ptosis, pupillary dilatation and anesthesia of the upper eyelid and forehead. It has been described after facial trauma. Other etiologies include infections, tumors or spontaneous hemorrhages in the retro-orbital space. Occurrence of SOFS after surgery in the skull base has not been described before. We recently encountered a case where a young female developed SOFS following surgery for cerebrospinal fluid (CSF) rhinorrhea...

BACKGROUND: Anal fissure is the most common anal disease in children. In the past few decades, the understanding of its pathophysiology has led to a progressive reduction in invasive procedures in favor of conservative treatment based on stool softeners and the relaxation of the anal sphincter. This randomized controlled study assessed the safety and efficacy of nitroglycerine (NTG) ointment in the treatment of pediatric anal fissure, which had not yet been proved. PATIENTS AND METHODS: An unequal randomized controlled study included 105 pediatric patients with anal fissure who had presented to the private and outpatient clinics of the Central Teaching Hospital of Pediatrics during the period from February 2015 to May 2016...

Anal fissures are a common problem and have a cumulative lifetime incidence of 11%. Previous reviews on anal fissures show inconsistent results regarding post-interventional healing and incontinence rates. In this review our aim was to compare the treatments for chronic anal fissures by incorporating indirect comparisons using network meta-analysis. The PubMed database was searched for randomized controlled trials (RCTs) published between 1975 and 2015. The primary outcome measures were healing and incontinence rates after lateral internal sphincterotomy (LIS), anal dilatation (DILA), anoplasty and/or fissurectomy (FIAP), botulinum toxin (BT) and noninvasive treatment (NIT)...

Fissure sealant (FS) and fluoride varnish (FV) are effective in preventing dental caries when compared with a no-treatment control. However, the relative clinical effectiveness of these interventions is uncertain. The objective of the study was to compare the clinical effectiveness of FS and FV in preventing dental caries in first permanent molars (FPMs) in 6- to 7-y-olds. The study design was a randomized clinical trial, with 2 parallel arms. The setting was a targeted-population program that used mobile dental clinics in schools located within areas of high social and economic deprivation in South Wales...

The molecular layer of the dentate gyrus and the anatomically adjacent stratum lacunosum-moleculare of CA1 area, represent afferent areas at distinct levels of the hippocampal trisynaptic loop. Afferents to the dentate gyrus and CA1 area originate from different cell populations, including projection cells in entorhinal cortex layers two and three, respectively. To determine the organization of oscillatory activities along these terminal fields, we recorded local field potentials from multiple sites in the dentate gyrus and CA1 area of the awake mice, and localized gamma frequency (30-150 Hz) oscillations in different layers by means of current source density analysis...

BACKGROUND: Retrospective studies to assess the distribution of oral diseases (ODs) are helpful in estimating the prevalence of oral diagnoses in the population, and thus help in preventive and curative services. Prevalence and frequency data for ODs are available from many countries, but information from Chile is scarce. MATERIAL AND METHODS: This study investigated the frequency of OD in a Chilean population. For this, we included all patients treated at the University of Talca (UTALCA, Chile) between 2001 and 2014...

Orbits are connected with the middle cranial fossa via the optic canal, the superior orbital fissure, the M-type orbitomeningeal foramen, the metoptic canal, an accessory anterior opening of the foramen rotundum, and Warwick's canal. They are also in communication with the anterior cranial fossa via the ethmoidal canals and the A-type orbitomeningeal foramen. The anatomy of these conduits has been recently enriched with several details that are summarized and reviewed in this article.

The practice of endodontics, while not as common as today, was performed during the WWII era. Some of the materials used to fill canals during this time period include gutta-percha, calcium hydroxide, gold foil, and silver points. In this case study, fissures and fractures were present on the exposed root surfaces of the dental remains. Radiographs of the dental remains revealed canal systems similar to those obturated with a paste or semi-solid material. The root surface defects appear to be the access point for the radiopaque material...

INTRODUCTION: Diffuse leptomeningeal glioneuronal tumor is a new entity under the neuronal and mixed neuronal-glial tumors in the WHO 2016 updated classification and commonly found in children and adolescents. The initial diagnosis is challenging because of its non-specific radiologic feature and negative CSF cytology analysis. A 17 years male was presented with intractable headache subsequently followed by back pain and joint pain. MRI showed enhancement of arachnoid membrane at basal cistern, bilateral sylvian fissure and cerebral cistern with slight enlargement of ventricles...
