Skin Dialogues in Atopic Dermatitis.

Atopic dermatitis (AD) is a chronic skin disorder associated with significant quality-of-life impairment and increased risk for allergic and non-allergic comorbidities. The aim of this review is to elucidate the connection between AD and most common comorbidities, as this requires a holistic and multidisciplinary approach. Advances in understanding these associations could lead to the development of highly effective and targeted treatments.

The Myth of Prometheus in metastatic meningioma to the liver: from craniotomy to hepatectomy.

Metastases from intracranial meningiomas are rare, and among them, meningiomas with hepatic dissemination are extremely rare. Therefore, there are currently no guidelines for staging and treatment of metastatic disease in meningioma, a disease that is a challenge for both the clinician and the pathologist. Our literature review revealed 24 cases of liver metastases originating from intracranial meningiomas.

The discovery of the circle of Willis as a result of using the scientific method in anatomical dissection.

There are numerous articles on the discovery of this arterial polygon, its history being quite long, beginning with the Antiquity and up to the Modern Era. Making an analysis of the primary and secondary sources on this topic, the purpose of this article is to identify the significant moments of the discovery of this arterial polygon, which is an anatomical structure with great importance for neurologists and neurosurgeons. We will present the contributions to this topic from Renaissance and early Modern Era anatomists, such as Andreas Vesalius, Jean Fernel, Gabriel Fallopius, Giulio Cesare Casseri, Adriaan van den Spiegel, Johann Vesling, and Johann Jakob Wepfer von Schaffhausen.

Natriuretic Peptides in Heart Failure with Preserved Left Ventricular Ejection Fraction: From Molecular Evidences to Clinical Implications.

The incidence of heart failure with preserved ejection fraction (HFpEF) is increasing and its challenging diagnosis and management combines clinical, imagistic and biological data. Natriuretic peptides (NPs) are hormones secreted in response to myocardial stretch that, by increasing cyclic guanosine monophosphate (cGMP), counteract myocardial fibrosis and hypertrophy, increase natriuresis and determine vasodilatation. While their role in HFpEF is controversial, most authors focused on b-type natriuretic peptides (BNPs) and agreed that patients may show lower levels.

Hydrocephalus of King Charles II of Spain, the Bewitched King.

King of the Spanish Habsburg dynasty and sovereign of the overseas Spanish Empire, Charles II of Spain, was physically disabled, disfigured, mentally retarded, and he proved impotent. He is known in history as El Hechizado (the Bewitched) because both him and the people believed that his mental and physical incapacity were due to a "witchcraft act." Although several authors speculated about different diseases, most of them genetic such as pituitary hormone deficiency, distal renal tubular acidosis, Klinefelter syndrome, fragile X syndrome, or male XX hermaphroditism, the hypothesis of hydrocephalus was not taken into account.

The Anatomy of Papal Tiara: A Story About Popes' Contribution and Protection of Anatomists.

Beginning with the thirteenth century, the papacy has exerted an important role in the development of anatomy and medical sciences through the protection and support provided to anatomists, who were in most cases the personal physicians of the popes as well. The work is intended to be a lesson of anatomy of Papal tiara, presenting the most important contributing popes, the anatomists-physicians whom they supported and protected and the relations between papacy and medical sciences.

Through Clinical Observation: The History of Priapism After Spinal Cord Injuries.

Since ancient times, physicians of antiquity noted the occurrence of priapism in some spinal cord injuries. Although priests saw it as a consequence of curses and witchcraft, after clinical observations of the Middle Ages and Renaissance, the first medical hypotheses emerged in the 17th-19th centuries completed and argued by neuroscience and neurology developed in the European laboratories and hospitals. This study aims to present a short overview of the history of clinical observations of posttraumatic male priapism after spinal cord injuries since antiquity until the beginning of the 20th century.

The selective odontoidectomy: endoscopic endonasal approach to the craniocervical junction.

Objective: The resection of the odontoid process via an extended endoscopic endonasal approach has been recently proposed as an alternative to the microscopic transoral method. We aimed to delineate a minimally invasive endoscopic transnasal odontoidectomy and to describe the endoscopic anatomy of the anterior craniovertebral junction (CVJ).

Materials And Methods: The anterior CVJ of 14 fresh adult cadavers were selectively accessed via a binostril endoscopic endonasal approach using 0- and 30-degree endoscopes.

Lymphocytic hypophysitis: an underestimated disease affecting the sellar region.

Hypophysitis is an inflammation of the pituitary gland and includes a heterogeneous group of diseases presenting with impaired pituitary gland function. Hundreds of cases have been reported after Goudie and Pinkerton's initial report on a young postpartum woman who died after progressive lymphocytic infiltration of the adenohypophysis in 1962. A 17-year-old woman presented with a three-year history of headache, galactorrhoea and excessive weight gain.

Operative illustrations of the Osborne's ligament.

The cubital tunnel syndrome is widely considered as the second most frequent compression neuropathy in the upper extremities although the existence of a compressive cause has not been determined conclusively. As far as we know, operational photography of compression of the ulnar nerve at the elbow is almost never found in the literature. In this paper, operational and pathological photographs of the Osborne's ligament as a cause of ulnar entrapment neuropathy at the elbow are presented.

Efficacy of clinical prognostic factors on survival in patients with glioblastoma.

Aim: Glioblastoma is the most common and highest-grade infiltrative astrocytoma. It is usually associated with a bad prognosis. Histological grading is highly predictive of an aggressive behavior, with a mean survival rate of 1 year.

Safe zone for C1 lateral mass screws: anatomic and radiological study.

Objective: To evaluate the possible complications of overpenetrated C1 lateral mass screws and to identify and define a "safe zone" area anterior to the C1 vertebra.

Methods: The study was performed on 10 cadavers and 50 random patients who had undergone computed tomographic scanning with contrast medium of the neck for other purposes. Atlas lateral mass screw trajectories were plotted, and the safe zone for screw placement anterior to the atlas vertebra was determined for each trajectory.

Neuroprotective effect of melatonin on experimental peripheral nerve injury: an electron microscopic and biochemical study.

Background And Study Aims: Melatonin is an important antioxidant agent with a protective role in the prevention of oxidative stress. We designed an experimental study which focused on the potential neuroprotective effect of melatonin on peripheral nerve injury.

Materials And Methods: Sciatic nerve injury was induced in the mid thigh region of 30 male Wistar rats by clip compression.

Ideal screw entry point and projection angles for posterior lateral mass fixation of the atlas: an anatomical study.

Although various posterior insertion angles for screw insertion have been proposed for C1 lateral mass, substantial conclusions have not been reached regarding ideal angles and average length of the screw yet. We aimed to re-consider the morphometry and the ideal trajections of the C1 screw. Morphometric analysis was performed on 40 Turkish dried atlas vertebrae obtained from the Department of Anatomy at the Medical School of Ankara University.

Delayed intraventricular tension pneumocephalus due to scalp-ventricle fistula: a very rare complication of shunt surgery.

Background: Although pneumocephalus and pneumoventricle are well known entities in neurosurgery practice, delayed intraventricular tension pneumocephalus following shunt surgery is extremely rare.

Case Description: A 60-year-old man presented with vomiting, drowsiness, walking difficulty, urinary incontinence and headache one month after shunt placement for communicant hydrocephalus developing secondary to aneurysmal subarachnoid hemorrhage. Skull X- Rays and Computed Tomography (CT) revealed marked air in both lateral ventricles.

Topiramate attenuates hippocampal injury after experimental subarachnoid hemorrhage in rabbits.

Objective: The aim of this study was to investigate the ability of topiramate (TPM) to prevent neural injury in a rabbit model of subarachnoid hemorrhage (SAH). The effect of TPM on cerebral vasospasm was also evaluated.

Methods: Fifty-three New Zealand white rabbits were allocated into three groups randomly.

Circumferential total resection of cervical tumors: report of two consecutive cases and technical note.

To date, few studies have addressed the subaxial vertebrectomy technique and related anatomical landmarks in this method. Total spondylectomy is performed via piecemeal resection or en bloc removal in a one-stage procedure associated with stabilizing the spine and preserving neurological status. In this presentation, a circumferential total cervical tumor resection for subaxial cervical spine lesions was described.

Effects of raloxifene on cerebral vasospasm after experimental Subarachnoid Hemorrhage in rabbits.

Background: The aim of this study was to investigate the ability of a SERM, RLX, to prevent vasospasm in a rabbit model of SAH.

Methods: Thirty-four New Zealand white rabbits were allocated into 3 groups randomly. Subarachnoid hemorrhage was induced by injecting autologous blood into the cisterna magna.

Posttraumatic infarction in the basal ganglia after a minor head injury in a child: case report.

We present a case of posttraumatic infarction in the territory supplied by the lateral lenticulostriate artery after a minor head injury in a child. A 2.5-year-old child was admited to our emergency room after a head-on fall from a height of 50cm.

Osteoblastoma of the temporal bone: a case report.

Benign osteoblastoma is an unusual primary bone tumor. It affects usually long bones or the vertebral column. Osteoblastoma affecting the calvarium is extremely rare.

Multiple aneurysms of the distal posterior inferior cerebellar artery: two case reports.

Introduction: The distal segment of the PICA (posterior inferior cerebellar artery) is a very rare localization for the occurrence of intracranial aneurysms. They are almost always presented with SAH (subarachnoid hemorrhage). Hydrocephalus often develops following intraventricular hemorrhage (IVH).

Hydatid cysts in uncommon locations in the same patient: simultaneous cardiac and spinal involvement.

Introduction: The spine and cardiac cavities are uncommon locations for hydatid disease. Spinal and cardiac hydatid cases separately constitute only 0.5-1% of all hydatid cases.

An effective and less invasive treatment of post-traumatic cerebrospinal fluid fistula: closed lumbar drainage system.

Cerebrospinal fluid (CSF) leakage may develop when a defect is formed in dural layers by traumatic or iatrogenic processes. Traumatic CSF leakage was encountered in 2% of head injuries. CSF leakage is an associated feature of 12-30% of skull base fractures.
