We report a case of an amebic brain abscess in a 2-year-old girl, with symptoms mimicking bacterial meningitis with no evidence of disease elsewhere. Histological evaluation of the abscess revealed the organisms, and the abscess regressed in response to specific medical treatment. This article reviews the rarity of these abscesses and difficulty in the diagnosis.
On the other hand, it is necessary to have a good knowledge of the anatomical structure of this region in the approach to OA Aneurysms. The variations on the arterial system of this region are more worthy of attention than the venous system (4,5,6,9,29).In neurosurgery, the recent advances in microsurgery techniques brought by technological developments have enabled an easier and more informed approach to surgery in this area. At the same time, the relationship between the anatomical structures of this area is just as important as before. It was with this aim that cadaver studies were used to investigate the relationship between the optic nerve and the █ INTRODUCTION A pproaches and indications for surgery on the optic canal are limited. However, this area has always attracted attention because of its position in the cranium and its relation to surrounding anatomical structures. Surgery is performed on the posterior orbit, the optic canal (OC), and the superior orbital fissure for injuries to the optic nerve which may occur as a result of trauma, for pseudotumor cerebri, angioma in the posterior orbit, neurinoma, meningioma, malignant tumors, and sphenoid wing tumors, and for ophthalmic artery (OA) aneurysms which have an extension inside the canal (3,13,14,17,19,27). AIm:A relationship was shown in this study between the optic canal and the ophthalmic artery by cadaver study. It is intended that the anatomical and histological values which we obtained can be used as a guide in surgery mATERIAl and mEThODS: A surgical anatomical evaluation was made of twenty optic canals in ten cadavers fixed in 10% formaldehyde. These were evaluated together with measurements of the ophthalmic artery and histological sections of the surrounding structure. RESUlTS:The ophthalmic artery separated from the carotid at different positions. In our material, eight (40%) left the carotid from the upper internal part, six (30%) from the front internal part, four (20%) from the upper central part, and two (10%) emerged at the end of the cavernous segment of the middle of the carotid at a steep angle. In none of the material did the ophthalmic artery originate from any other vascular structure than the carotid. Whatever position the ophthalmic artery was in within the canal on entry, it followed the outer walls of the canal and left the canal in the lower external section of the optic nerve. In the literature, work on this area has been limited to examining the anatomical values and variations in the optic canal. The results in the present study have been obtained by combining the data with surgical anatomy.CONClUSION: This is a method of transcranial decompression of the optic canal which is safe for the vascular structures in and around the optic canal providing certain points are kept in mind.
consulting a physician in these patients. Sleep disorders are in the second place after brachialgia with a ratio of 64% (5,12,24,27).Sleep disorders are frequently seen in patients with chronic low back pain (17). In another study, pain was shown to be the most important factor impairing quality of sleep (23). Other studies demonstrated a significant relationship between the severity of pain and the impairment in sleep quality. It has been also shown that quality of sleep improves after the treatments focusing on the cause of pain (5,6).In addition to chronic pain syndromes, there are a lot of studies on sleep disorders in patients who underwent open heart surgery, major abdominal surgery and thoracic surgery which were targeted to the disease underlying the pain (29). In the █ INTRODUCTION C ervical disc herniation (CDH) is characterized by compression of the motor and sensory tracts of cervical nerve roots (radiculopathy) and/or compression of the motor and sensory tracts of the long pathways in the spinal cord (myelopathy) as a result of degenerative events in the cervical vertebrae. An intractable and severe pain radiating from the neck down to the arm (brachialgia) and progressive neurological deficits associated with radiculopathy and/or myelopathy findings in cervical magnetic resonance imaging (MRI) are the major surgical indications in patients with CDH. The surgical procedure in CDH is at the same time a surgical procedure for pain relief. Brachialgia associated with radiculopathy and myelopathy is the main reason for AIm: To analyze the relationship between the severity of pain and sleep disorder using wrist actigraphy in patients with cervical disc herniation (CDH). mATERIAl and mEThODS:Fifty patients with the diagnosis of CDH underwent subjective tests and actigraphic analysis in preoperative period, and at the end of postoperative first week and postoperative first month. The data of the subjective tests and actigraphic analysis were compared. RESUlTS:There was a strong and statistically significant negative correlation between the subjective tests of Visual Analog Scale (VAS) for Pain 0-1-2 and the objective parameters of Sleep Onset Latency (SOL) 0-1-2 (rs= -0.798, p=0.009 -rs= -0.832, p=0.006 -rs=-0.710, p=0.004). There was a positive correlation between the subjective tests of VAS for Pain 0-1-2 and the objective parameters of Sleep Efficiency (SEF) 0-1-2 (rs=0.721, p=0.006 -rs= 0.768, p=0.001 -rs= 0.748, p=0.001).CONClUSION: Actigraphy may be used for the evaluation of cervical disc surgery, as an alternative and objective test for sleep disorders.
