CROATIAN VERSION OF THE QUALITY OF RECOVERY QUESTIONNAIRE (QoR-40): TRANSCULTURAL ADAPTATION AND VALIDATION.

The Quality of Recovery-40 (QoR-40) questionnaire is a psychometric instrument designed to quantify postoperative recovery. It has been translated and validated in several countries but not in Croatia. The aim was to translate, cross-culturally adapt, and validate Croatian version of the QoR-40. The QoR-40 was translated from English by two independent translators, back-translated by a native speaker, and approved by an expert committee. The questionnaire was administered to 106 patients who underwent general anesthesia before elective spinal surgery, post-surgery in the operating room, and 30 days after surgery. Internal consistency was assessed using the Cronbach's alpha coefficient. Construct validity was assessed by evaluating correlation between the QoR-40 and hand grip strength. The mean preoperative global QoR-40 score was 177.6 (95% CI 174.9-180.3) and postoperative 168.9 (95% CI 165.8-171.9); the mean change was -8.8 (95% CI -11.9 to -5.6). Internal consistency was good for global QoR-40 score (Cronbach α=0.896), acceptable across all domains (8>α≥7). There was a significant correlation between grip strength and total QoR-40 score, pain, and physical independence, but not with other domains. In conclusion, the Croatian version of the QoR-40 has acceptable properties and can be used in the assessment of postoperative recovery in Croatian patients.

DOES THE TYPE OF SURGERY IN BRAIN ABSCESS PATIENTS INFLUENCE THE OUTCOME? ANALYSIS BASED ON THE PROPENSITY SCORE METHOD.

There are different options for surgical treatment of brain abscess, mainly standard craniotomy and stereotactic aspiration. It has not yet been established which of these options is associated with a more favorable outcome under similar baseline conditions of patients. Demographic characteristics, microbiology, clinical presentation, and treatment outcome were analyzed for surgically treated adult patients with brain abscess over a 14-year period. A propensity score model was applied to account for baseline conditions that may determine the choice of neurosurgical method. The propensity score was included in the prediction of a favorable outcome, defined as a Glasgow Outcome Scale (GOS) score 4 or 5. We analyzed 91 adult surgically treated patients, of which 53 had standard craniotomy and 38 stereotactic aspiration of brain abscess. Focal neurological deficit was the most common symptom present in 60 (65.9%) patients on admission. Sixty-seven (73.6%) patients had GOS 4 or 5, and seven (7.7%) patients died. The choice of surgery did not influence the outcome (OR 1.181, 95% CI 0.349-3.995), neither did the time elapsed from diagnosis to surgery (OR 0.998, 95% CI 0.981-1.015). Propensity towards standard craniotomy procedure did not influence outcome in brain abscess patients (OR 1.181, 95% CI 0.349-3.995). Worse outcome (GOS below 4) was independently associated with Glasgow Coma Score (GCS) on admission (OR 0.787, CI 0.656-0.944). The choice of neurosurgical procedure did not influence the outcome in patients with brain abscess. Patients with brain abscess who had lower GCS on admission also had worse outcome.

The application of ultrasound in neuroendoscopic procedures: first results with the new tool "NECUP-2".

In this paper, our experience with originally constructed Neurosurgical Endoscopic Contact Ultrasound Probe "NECUP-2" in neuroendoscopy is reported. Between June 1997 and June 2007, 132 neuroendoscopic procedures have been performed: 102 endoscopic thrid ventriculostomies (ETV), 15 arachnoid cysts and 5 intraventricular tumours operations. The "NECUP-2" was applied effectively in all cases in which blunt perforation was not possible: 38/102 ETY, 10/10 septostomies, 15/15 arachnoid cysts. In five cases of intraventricular tumours, neuroendoscopic procedure was combined with open microsurgery for tumour removal with preservation of vascular structures. There were no "NECUP-2" related complications. Of postoperative complications, we had liquorrhea (9 patients), and symptoms of meningitis (6 patients). In the follow-up period (6 months to 6 years), we had a patency rate of 80% (50/63 patients). All patients improved in clinical status. According to the first results, it seems that ultrasonic contact probe NECUP-2 presents a new device in neurosurgical armamentarium that can be used in various fields of neurosurgery. With minimal and controlled lesion that is produced at the tip of the probe, it can be used in highly demanding operations such as third ventriculostomy and tumour resection.

Reconstruction of a soft tissue defect of the back after myelomeningocele closure with modified V-Y plasty.

Myelomeningocele is a congenital defect in vertebral arches with cystic dilatation of meninges and structural or functional abnormality of spinal cord or cauda equina. It is a form of spinal dysraphisam with overlying skin defect (spina bifida aperta). That condition is related to other clinical complications such as infection that can produce furthermore complications. To prevent rate of complications surgical treatment in first 24 h is strongly suggested. In this case report we describe a patient (infant) with congenital myelomeningocele who's defect was treated surgically by the neurosurgeon. In operative procedure plastic surgeon was involved to cover the skin defect remaining after neurosurgical closure of spinal canal. Bilateral advancement local skin flaps were used in soft tissue defect closure. Review of the literature that refers to advancement local skin flaps was carried out.

Peptide therapy with pentadecapeptide BPC 157 in traumatic nerve injury.

We focused on the healing of rat transected sciatic nerve and improvement made by stable gastric pentadecapeptide BPC 157 (10 microg, 10ng/kg) applied shortly after injury (i) intraperitoneally/intragastrically/locally, at the site of anastomosis, or after (ii) non-anastomozed nerve tubing (7 mm nerve segment resected) directly into the tube. Improvement was shown clinically (autotomy), microscopically/morphometrically and functionally (EMG, one or two months post-injury, walking recovery (sciatic functional index (SFI)) at weekly intervals). BPC 157-rats exhibited faster axonal regeneration: histomorphometrically (improved presentation of neural fascicles, homogeneous regeneration pattern, increased density and size of regenerative fibers, existence of epineural and perineural regeneration, uniform target orientation of regenerative fibers, and higher proportion of neural vs. connective tissue, all fascicles in each nerve showed increased diameter of myelinated fibers, thickness of myelin sheet, number of myelinated fibers per area and myelinated fibers as a percentage of the nerve transected area and the increased blood vessels presentation), electrophysiologically (increased motor action potentials), functionally (improved SFI), the autotomy absent. Thus, BPC 157 markedly improved rat sciatic nerve healing.

[Neurofibromatosis type 2 (central neurofibromatosis or bilateral acoustic neuromas, vestibular schwannomas): from phenotype to gene]. / Neurofibromatoza tip 2 (centralna neurofibromatoza ili bilateralni akusticki neuromi, vestibularni svanomi): od fenotipa do gena.

Neurofibromatosis type 2 (NF2) is an autosomal dominant disease that predisposes to bilateral vestibular schwannomas (neurinomas), other central and peripheral nervous system tumours (multiple meningeomas and neurofibromas) and ocular abnormalities (cataract). The NF2 tumour suppresor gene is localised on chromosome 22q12 and encodes protein called schwannomin or merlin which is related to a family of cytoskeleton-to-membrane proteins linkers ERM (ezrin-radixin-moesin proteins). About 50% of all cases are new germline mutations, although about 20% of apparently sporadic cases represent somatic mosaicism. The majority of observed germline NF2 mutations are point mutations which result in schwannomin with an altered or absent C-terminal domain. NF2 has a variable clinical presentation, with two basic types: severe type having early onset and progressive growth of tumors and the milder type having later onset and less aggressive course. The genotype-phenotype correlations indicate a greater variability of clinical disease expression. In this paper we discuss the epidemiology, genetic and clinical characteristics, diagnostic criteria, investigations, screening for risk persons and recommendations for care and therapy of patients with NF2.

Mutation in exon 7 of PTCH deregulates SHH/PTCH/SMO signaling: possible linkage to WNT.

The novel PTCH mutation and clinical manifestations within Gorlin syndrome family links PTCH haploinsufficiency and aberrant activation of the Wnt pathway. We report a family case with Gorlin syndrome, characterized by the usual phenotype features such as widespread basocellular tumors and craniofacial and bone malformations, but also including a less common appearance of craniopharyngioma. These clinical manifestations might be associated with a novel constitutional mutation of the PTCH gene, 1047insAGAA, which we found in exon 7. It changes the normal amino acid sequence leading to termination of the PTCH protein at exon 9. The analyzed tumors of the family show extensive loss of heterozygosity in the PTCH region, both basocellular and in particular craniopharyngioma, and in the latter a high expression of beta-catenin was detected. Our findings suggest involvement of the SHH/PTCH/SMO pathway in pathogenesis of the analyzed disorders, including its possible contribution to aberrant activation of the Wnt pathway in craniopharyngioma.

Internal quality audit and quality standards as a method of quality improvement at the Department of Ophthalmology, University Hospital.

Quality assessment of clinical health care with the programme of quality standard is a method of health management, through which better efficiency and safety of health outcomes can be achieved. In the period from 2002 to 2004, a pilot program of quality has been carried out on the Department of Ophthalmology, University Hospital Center in Zagreb. Seven internal audit teams of hospital commission and teams of hospital departments were evaluating introducing practice for quality standards every three months. In the period of two years improvement in all standards of quality has been noticed (expressed in percent of progress towards the ideal result of 100%): personnel 20%, patient rights 15%, medical equipment 40%, quality of emergency service 60%, implementation of clinical guidelines and criteria for elective admission 55%, quality of risk prevention 70%, quality of medical records 60%. The two-years-improvement dynamics of about 46%, first year 24%.
