Circadian Biorhythmicity in Normal Pressure Hydrocephalus - A Case Series Report.

Continuous monitoring of intracranial pressure is a well established medical procedure. Still, little is known about long-term behavior of intracranial pressure in normal pressure hydrocephalus. The present study is designed to evaluate periodicity of intracranial pressure over long-time scales using intraventricular pressure monitoring in patients with normal pressure hydrocephalus.

Missing Skeletal Muscle Metastases of Papillary Thyroid Carcinoma.

With regard to several important gaps in the work "Skeletal Muscle Metastasis in Papillary Thyroid Microcarcinoma Evaluated by F18-FDG PET/CT" [...

Incidental detection of unexpected neck lymphatic III level node metastasis from occult papillary thyroid carcinoma during cervical disc surgery: first literature report.

Expanding Cyst of the Septum Pellucidum - Endoscopic Observations on the Mechanism of Development and Results of Treatment.

Cysts of the septum pellucidum (CSP) are usually asymptomatic; however, in some cases they can begin expanding and cause neurological deterioration. The mechanism leading to the formation of an expanding cyst of the septum pellucidum (ECSP) is not known. Based on observations made during endoscopic treatment of ECSP we analyzed intraoperative findings in respect to cyst formation mechanism and treatment prognosis.

From paradigm to paradox: divergency between intracranial pressure and intracranial pulse pressure during atmospheric pressure fall. A case study.

Background: The main objectives are to determine relation between intracranial pressure (ICP) and its amplitude and to ascertain meteorological variables as possible confounding factors. This is a retrospective observational study of a patient with suspicion of normotensive hydrocephalus.

Methods: The intracranial pressure, the blood pressure, atmospheric pressure and geomagnetic activity were continuously monitored capturing extraordinary sudden and unexpected atmospheric pressure fall.

Skeletal muscle metastases from papillary and follicular thyroid carcinomas: An extensive review of the literature.

Skeletal muscle metastasis of papillary or follicular thyroid cancer (PTC/FTC) is a rare finding; only 11 cases of skeletal muscle PTC or FTC metastasis have been included in medical literature reviews. The aim of this study was to identify all published cases of PTC and FTC muscle metastases and derive the true incidence of this malignancy. The probability of detecting the skeletal muscle metastasis of PTC and FTC was calculated based on epidemiological data.

Massa versus Haller: Priority of the Cerebrospinal Fluid Discovery.

The commonly accepted practice in recognizing the scientific priority of a discovery requires finding a hitherto unknown phenomenon, publishing it to other scholars and doing it for the first time. And this is what happened regarding the discovery of the intracranial fluid presence by the Venetian anatomist Massa in 1536. This finding fulfills all the conditions necessary for the recognition of the scientific discovery.

The major influence of the atmosphere on intracranial pressure: an observational study.

The impact of the atmosphere on human physiology has been studied widely within the last years. In practice, intracranial pressure is a pressure difference between intracranial compartments and the surrounding atmosphere. This means that gauge intracranial pressure uses atmospheric pressure as its zero point, and therefore, this method of pressure measurement excludes the effects of barometric pressure's fluctuation.

The maze of the cerebrospinal fluid discovery.

The author analyzes a historical, long, and tortuous way to discover the cerebrospinal fluid. At least 35 physicians and anatomists described in the text have laid the fundamentals of recognition of this biological fluid's presence. On the basis of crucial anatomical, experimental, and clinical works there are four greatest physicians who should be considered as equal cerebrospinal fluid's discoverers: Egyptian Imhotep, Venetian Nicolo Massa, Italian Domenico Felice Cotugno, and French François Magendie.

Assessment of economic effectiveness in treatment of neuropathic pain and refractory angina pectoris using spinal cord stimulation.

Background: The implementation of new diagnostic and therapeutic technologies is related to expanding financial needs. The escalation of expenses for health protection and simultaneous economic problems has resulted in an interest in the subject of economic assessment. Decision makers in the health sector should have reasonable tools that will allow them to make complex evaluations of the economic suitability of health technologies.

Experimental determination of the Stern layer thickness at the interface of the human arachnoid membrane and the cerebrospinal fluid.

The paper is part of an investigation of the electrostatic forces contributing to the interaction between colloidal molecules, suspended in the cerebrospinal fluid, with other molecules of the cerebrospinal fluid and with the surrounding environment. The study is based on experimental observations and theoretical considerations. We are reporting about the microscopic observation of particles suspended in the cerebrospinal fluid which was obtained by lumbar puncture of 27 neurosurgery patients.

Pseudomeningeal syndrome of Dupre associated with cervical discopathy--case report.

Background And Purpose: The below publication presents a case of a 51-year-old patient with cervical discopathy of unusual clinical course.

Case Report: The symptoms of the disease suddenly became aggravated and took a form of meningeal syndrome without inflammation of cerebrospinal fluid. The authors emphasize the symptomatology and diagnostic difficulties connected to unusual clinical course of cervical discopathy at the level of VC3/VC4.

Atmospheric pressure and basic parameters of intracranial volume-pressure homeostasis.

Background And Purpose: There are only a few studies in the literature regarding the influence of atmospheric pressure on intracranial homeostasis and the mechanism of the relation has not been clarified. The aim of the study was to evaluate the influence of atmospheric pressure and ambient temperature on parameters of intracranial volume-pressure homeostasis including intracranial pressure and cerebral perfusion pressure as well as on blood pressure and body temperature.

Material And Methods: The authors analyzed the influence of atmospheric pressure on intracranial pressure, blood pressure, cerebral perfusion pressure and body temperature in 14 patients who were monitored because of suspicion of having normal pressure hydrocephalus.
