Aim To analyze the relationship between timing of surgery and outcome in patients with cauda equina syndrome caused by lumbar disc herniation. Methods A retrospective, non-randomized clinical study included 25 consecutive patients with cauda equina syndrome (CES) caused by lumbar disc herniation. All patients were operated within 24 hours after hospitalization at the Department of Neurosurgery, Cantonal Hospital Zenica, Bosnia and Herzegovina, between January 2000 and December 2010. All patients were evaluated before surgery on the basis of complete history, neurological examination and neuroimaging evaluations using CT (computed tomography)and MRI (magnetic resonance imaging). Results Statistically significant difference between preoperative and postoperative bladder (p=0.05) and bowel (p=0.05) function was found. A significant number of patients had bladder and bowel recovery after surgery, nine (36%) and 11 (44%), respectively. Significant recovery of muscle strength was noted with complete recovery(5/5) in 12 (48%) and partial recovery in 13 (52%) patients. Complete sensory recovery was noted in 16 (64%), incomplete in four (16%), and in five (20%) patients there were no changes. Most commonly, patients with complete sensory recovery were operated within 48 hours of symptom onset. In most patients early surgery was associated with better outcome. Conclusion This research showed that early decompression correlated with better outcome. Patients with cauda equina syndrome must be cleared for surgery in optimal conditions and, if it possible within optimal timing for recovery (within 48 hours).

Aim To establish presence of segmental instability in patients operated with standard discectomy comparing measurement of translation and rotation on postoperative functional radiographs of lumbosacral spine with reference values,and to explore difference between patients operated on one or two levels. Methods The study included 71 patients, who were operated due to herniated lumbar disc. They were divided into two groups operated on one level (group A) or two adjacent levels (group B). All patients had been imaged in a standing position with functional lateral radiography. Radiographic images were digitized and then computerized measurement of translation and rotation was made. Measurement data were compared between the groups and with reference values obtained in healthy adults. Results Standard lumbar discectomy leads to an increase in translation, however, it reached statistical significance only for L4/L5 level and a decrease of rotation, which showed statistical significance for all samples, relative to the reference values. There was no statistically significant difference in the values of translation and rotation between the groups for corresponding levels, except for the value of the rotation for L4/L5 level as adjacent, unoperated level. Comparison of translation and rotation between the operated and adjacent levels did not show a statistically significant difference. When it comes to comparing the measured and predicted translation, there was a statistically significant difference only at the L5/S1 as anunoperated level. Conclusion Standard discectomy does not lead to radiologically significant segmental instability, and two-level surgery has not caused more pronounced signs of instability comparing to onelevel surgery.

Abstract In this case, we have presented a 55-year old patient with dysuria and bloody urine. He was hospitalized at the Urology Department of County Zenica Hospital due to obstructive uropathy. Diagnostics showed the cause is a large bleeding mass in prostatic part of urethra. After cystectomy, immunohistochemistry revealed urachal adenocarcinoma, rare type of urogenital carcinomas, presented only in 5% of all cancer types. He was treated with dual modality, chemotherapy and radiotherapy

Objective – We report an unusual case of split cord malformation (SCM) associated with open spinal dysraphism and other anomalies of the central nervous system. Case report – A male newborn was admitted to the Pediatric Intensive Care Unit immediately after birth by Caesarean delivery. Clinical examination and diagnostics (MRI) showed open spinal dysraphism in the distal part of the spine (level L5 and S1), split cord malformation type I which separated two hemicords, tethered cord and syringomyelia. Two days after birth microneurosurgery was performed. Cranial and cervical MRI showed Chiari I and corpus callosum hypoplasia. There was no hydrocephalus. Preoperatively the patient had paraparesis and discretely moved his left foot. MRI showed a dilated bladder so he may have had urinary retention. The postoperative recovery was satisfactory. The patient did not have any additional neurological deficit. The patient was followed up by a neurosurgeon, pediatric surgeon, pediatrician and physiatrist. Control MRI scans showed significant regression of the syrinx and some ascensus of the medulla. About 18 months after operation the patient had discrete paresis of the left foot. Conclusion – Complex spina bifida is an extremely rare condition. In this paper we describe this interesting case of complex spina bifida: a split cord malformation characterized by atypical bony morphology with a dural fold into the bone septum.

Objective – To analyze the clinical and histological characteristics, as well as to evaluate the results of surgical treatment of pediatric neuroepithelial tumors. Patients and methods – A retrospective study was conducted, including 40 pediatric patients surgically treated at the Clinic of Neurosurgery, University Clinical Hospital Tuzla in the period 2002-2012. During the study we formed groups and the analysis was conducted by age, gender, clinical signs, histopathologic types and type of surgical treatment. The results are presented in tables and expressed by relative values. Results – Neuroepithlial tumors are more common in male patients. There was no statistically significant difference in distribution of neuroepithelial tumors (I‡2=0.400; p=0.527) related to supratentorial and infratentorial localization. Infratentorial neuroepithelial tumors are most common at a younger age (F=6.516; p=0.015). Increased intracranial pressure and seizures are the most common initial presentation of neuroepithelial tumors (I‡2=0.022; p=0.882). There was no statistically significant difference between types of surgical resection and localization of the tumor. Usually we performed total resection (I‡2=0.246; p=0.620). There was a statistically significant difference in tumor grade regarding supratentorial and infratentorial localizations (p=0.013). Infratentorial tumors are higher grade (I‡2=5.495; p=0.019). Conclusion – The most common initial presentations of neuroepithelial tumors are increased intracranial pressure and seizures. Infratentorial tumors are higher grade. The most common initial treatment of neuroepithelial tumors is radical surgical resection.

Carcinoma of unknown origin is defined as the absence of primary tumor and biopsy proved the existence of metastatic changes. The incidence is about 3% of all cancers. We present a case of a patient who underwent surgery for left breast mammography verified pathological lymphonodes on the left breast and on the left axillary region. Histopathological analysis of excised tissue showed the absence of malignant disease in the breast. A complete diagnostic evaluation also did not confirm the primary lesion. We done fluorodeoxyglucosa positron emission tomography, which had set suspicion of primary breast cancer, but biopsy and pathological reverification were not confirmed. The patient spent six cycles of chemotherapy for cancer of unknown origin. After a year and six months because of sudden right side hemiparesis were performed Computed Tomography and Magnetic Resonance imaging of the head, which indicated that it was a metastatic brain tumour. After metastasectomy, histopathological finding was finally proved to be a metastasis of breast adenocarcinomas. The patient had irradiation of the cranium, and began chemotherapy protocol for breast cancer. In this case, insufficient diagnosis did not affect in the proper therapeutic approach.
