Transgluteal approach for excision of pelvic lipoma causing sciatic pain.

Sciatic nerve pain, affecting 12%-27% of the general population, often arises from a myriad of etiologies due to the complex anatomy of the sciatic region. The intricate relationship between the sciatic nerve and surrounding structures in the pelvis poses significant challenges in both diagnosis and surgical management. We report two cases of adult female patients presenting with chronic sciatic pain, refractory to conservative treatment.

A Case-Control Study of the Fokl Polymorphism of the Vitamin D Receptor Gene in Bulgarians With Lumbar Disc Herniation.

Background: The present study investigates whether vitamin D receptor (VDR) gene polymorphisms play a role in intervertebral disc degeneration (IDD), a common cause of low back pain (LBP) and reduced quality of life. Specifically, we examined the FokI VDR polymorphism and its potential association with lumbar disc herniation (LDH) in patients from Bulgaria. Previous studies have suggested a link between mutations in the VDR gene and IDD.

Histone H1.0--a potential molecular marker with prognostic value for patients with malignant gliomas.

Background: Histones are proteins closely associated with the DNA molecules and serve as a structural scaffold for the organization of chromatin. They play an important role in the regulation of gene expression by changing the level of DNA compaction. The special subtype of the linker histone family-H1 zero (H1.

[The transcortical frontal approach in putaminal hypertensive intracerebral haematomas].

Unlabelled: Spontaneous putaminal intracerebral haematomas (ICH) related to arterial hypertony are a relatively often type of pathology in the CNS. Classically such haematomas are operated through a transsylvian or temporal approach. With the development of minimally invasive neurosurgery and neuroendoscopy literature data appears describing an alternative path of evacuation through the frontal lobe without a determination of a separate approach.

[Epidermoid cysts in the pineal region--analysis of four cases and review of the literature].

Epidermoid cysts represent 0.2-1% of all intracranial tumours. Extremely rare they are found in the pineal region.

[Injuries of the cranio-cervical junction--anatomy, classification of pathological process, and diagnosis].

The cranio-atlanto-axial junction (C0-C2) is anatomically and biomechanically the most complex spinal region. It is frequently engaged by different pathologies of tumoral, traumatical or inflammatory origin, leading to spinal instability. The advanced knowledge about the anatomical details, the physiology, the mechanism of injury, the nature of the processes and their classification are crucial for the adequate therapeutic approach when dealing with pathologies in this region.

[Quality of life assessment in patients with malignant glial tumors].

Introduction: High-grade gliomas are the most common primary brain tumors. Dismal prognosis for the patients with a marked deterioration of the quality of life and a mean length of survival of 9-18 months are typical characteristics for this pathology. The aim of this study is to assess the most appropriate questionnaire for measuring the quality of life (QOL) in this group of patients.

[Distal aneurysm of the anterior carotid artery--case report and review of the literature].

Introduction: Aneurysms of the internal carotid artery (ICA)-anterior choroid artery (ACHA) are about 2-5% of all intracerebral aneurysms. The neck of the aneurysm typically engages both arteries. Aneurysms located on the ACHA itself without engaging the ICA present a rare pathology.

[Paget's disease as a cause for symptomatic basilar impression--a case report and review of the literature].

Introduction: We report a case of a 52-years old women with Paget's disease. A secondary symptomatic basilar impression was observed, causing quadriparesis, bulbar palsy and ataxia

Clinical Presentation: We report a case of a 52-year old woman with history of/periodic headache. In the last 6 months the complaints became more intensive and continuous.

[Application of intervertebral carbon implants for the treatment of cervical disk herniation].

Introduction: We are presenting our preliminary experience with the cervical intervertebral carbon cages (CICC) as a treatment option for interbody fusion in cases with cervical disk herniation.

Material And Methods: For the period 08.2003-08.

[Posterior screw fixation for craniocervical junction instability].

Introduction: The craniocervical junction (C0-C2) is anatomically and biomechanically the most complex spinal region. It is frequently engaged by different pathologies of tumoral, traumatic or inflammatory origin, leading to spinal instability. We are presenting our experience with the posterior screw fixation for the treatment of the craniocervical junction instabilities.

[Clinical assessment in patients presenting brain metastases].

Over the period January 1988 to January 1998, in the clinic of emergency neurology and neurosurgery of the University Hospital "Queen Giovanna"--Sofia a total of 348 patients with brain tumors are hospitalized. Of them 329 cases are subjected to operation, and in 19 no surgery is undertaken. Forty-four patients with metastatic brain tumors are operated, and in 14 no operation is done.

[Intracranial hemorrhages in patients being treatment with anticoagulants].

Over the period 1994-1998, five patients presenting coagulation status impairment in the course of sintrom treatment are hospitalized in the Clinic of Emergency Neurology and Neurosurgery. Three of them are with craniocerebral trauma (2 severe forms--score 5 by the Glasgow Coma Rating scale, and one mild form--score 15), one has spontaneous intracerebral hematoma, and one--acute hydrocephalus against the background of ruptured aneurysm of the basilar artery (score 4). Three patients are given sintrom treatment because of rheumatic heart disease (2 with mitral valve prosthetic replacement and one in the post-commissurotomy period), and two--because of absolute arrhythmia, complicated by systemic emboli in the extremities and/or pulmonary artery.
