Clinical and psychological outcome after surgery for lumbar spinal stenosis: A prospective observational study with analysis of prognostic factors

Background The identification of psychological risk factors is important for the selection of patients before spinal surgery. Moreover, the effect of surgical decompression in lumbar spinal stenosis (LSS) on psychological outcome is not previously well analyzed. Aim of paper to investigate clinical and psychological outcome after surgery for LSS and the effect of depressive symptoms and anxiety on the clinical outcome. Materials and methods A total of 25 patients with symptomatic LSS underwent decompressive surgery with or without spinal stabilization were prospectively enrolled in this observational surgery. The Symptom Checklist-90-Revised (SCL-90-R) was used to assess global psychological distress with a summary score termed Global Severity Index (GSI) and single psychological disorders including depression (DEP) and anxiety (ANX). The clinical outcome of surgery was evaluated with the Oswestry Disability Index (ODI) and visual analogue scale (VAS) pain assessment. Results Compared with baseline, there was a statistically significant improvement in VAS, ODI and GSI after surgery (p<0.05) in all patients. Univariate analysis revealed that patients with high GSI and anxiety and depression scores had significantly higher ODI and VAS scores in the follow-up with a bad outcome. Conclusions Surgery for spinal stenosis was effective to treat pain and disability. In this prospective study baseline global psychological distress, depression and anxiety were associated with poorer clinical outcome

Značajke liječenja i ishoda u starijih bolesnika s glioblastomom mozga: retrospektivna analiza niza slučajeva

Treatment modalities affecting quality of life and survival in elderly brain glioblastoma patients are not well defined. A single-institution data were analyzed during a 3-year period to disclose prognostic difference in management related to age. Karnofsky Performance Scale (KPS), overall survival (OS), and adjuvant therapy were evaluated. The case group comprised of elderly patients (>75 years), while the control group included those of younger age (<65 years). The investigated variables were correlated between the groups. Twenty elderly patients and a corresponding number of younger ones were analyzed. Preoperative KPS >70 indicated longer overall survival. Statistically significant correlation was recorded in both the control (p=0.036) and case (p=0.0053) groups. Lower postoperative KPS was significantly correlated with shorter OS in elderly patients (p=0.023). The correlation between the extent of tumor resection and OS was statistically significant in younger patients only (p=0.04). Overall survival was significantly shorter in elderly patients regardless of the extent of tumor resection (p=0.0057). Adjuvant therapy was significantly associated with longer OS in both the case (p=0.032) and control (p=0.013) groups. Elderly population is a more endangered group of surgical brain glioblastoma patients having lower quality of life and shorter overall survival. The management protocol should be personalized for each individual case in this age group of patients to reduce postoperative complications and grant a satisfactory quality of life.Modaliteti liječenja od utjecaja na kvalitetu života i preživljavanje starijih bolesnika s glioblastomom još nisu jasno određeni. Kako bi se utvrdila prognostička razlika u primijenjenim oblicima liječenja u odnosu na dob bolesnika analizirani su podaci dobiveni trogodišnjim istraživanjem uzorka. Istraživani su sljedeći pokazatelji: Karnofskyjeva ljestvica (KPS), vrijeme ukupnog preživljavanja i primjena pomoćnog liječenja. Oglednu skupinu činili su stariji bolesnici (≥75 godina), a kontrolnu skupinu oni mlađe dobi (≤65 godina). Međusobno su uspoređivani istraživani parametri iz obje skupine bolesnika. Promatrano je 20 starijih i odgovarajući broj mlađih bolesnika. Prijeoperacijski KPS >70 upućivao je na dulje sveukupno preživljavanje. Statistički značajna korelacija zabilježena je u bolesnika kontrolne (p=0,036) i ogledne (p=0,0053) skupine. Niže poslijeoperacijske vrijednosti KPS bile su značajno povezane s kraćim vremenom preživljavanja u starijih bolesnika (p=0,023). Korelacija između opsežnosti tumorske resekcije i sveukupnog preživljavanja bila je statistički značajna samo u mlađoj dobnoj skupini (p=0,04). Vrijeme sveukupnog preživljavanja bilo je značajno kraće u starijih bolesnika neovisno o stupnju kirurške resekcije (p=0,0057). Primjena pomoćne terapije bila je značajno povezana s duljim sveukupnim preživljavanjem u oglednoj (p=0,032) i kontrolnoj (p=0,013) skupini. U zaključku, starija je populacija ugroženija skupina kirurških bolesnika s glioblastomom u kojih je smanjena kvaliteta života i skraćeno vrijeme sveukupnog preživljavanja. Stoga je potrebno protokol liječenja prilagoditi svakom pojedinom bolesniku iz ove dobne skupine kako bi se smanjio udio poslijeoperacijskih komplikacija i poboljšala kvaliteta života

The Incidence of Adjacent Segment Degeneration after the Use of a Versatile Dynamic Hybrid Stabilization Device in Lumbar Stenosis: Results of a 5–8-Year Follow-up

Study DesignRetrospective study with long-term follow-up.PurposeTo evaluate the long-term incidence of adjacent segment degeneration (ASD) and clinical outcomes in a consecutive series of patients who underwent spinal decompression associated with dynamic or hybrid stabilization with a Flex+TM stabilization system (SpineVision, Antony, France) for lumbar spinal stenosis.Overview of LiteratureThe incidence of ASD and clinical outcomes following dynamic or hybrid stabilization with the Flex+TM system used for lumbar spinal stenosis have not been well investigated.MethodsTwenty-one patients with lumbar stenosis and probable post-decompressive spinal instability underwent decompressive laminectomy followed by spinal stabilization using the Flex+TM stabilization system. The indication for a mono-level dynamic stabilization was a preoperative magnetic resonance imaging (MRI) demonstrating evidence of severe disc disease associated with severe spinal stenosis. The hybrid stabilization (rigid-dynamic) system was used for multilevel laminectomies with associated initial degenerative scoliosis, first-grade spondylolisthesis, or rostral pathology.ResultsThe improvement in Visual Analog Scale and Oswestry Disability Index scores at follow-up were statistically significant (p<0.0001 and p<0.0001, respectively). At the 5–8-year follow-up, clinical examination, MRI, and X-ray findings showed an ASD complication with pain and disability in one of 21 patients. The clinical outcomes were similar in patients treated with dynamic or hybrid fixation.ConclusionsPatients treated with laminectomy and Flex+TM stabilization presented a satisfactory clinical outcome after 5–8 years of follow-up, and ASD incidence in our series was 4.76% (one patient out of 21). We are aware that this is a small series, but our long-term follow-up may be sufficient to contribute to the expanding body of literature on the development of symptomatic ASD associated with dynamic or hybrid fixation

New or Blossoming Hemorrhagic Contusions After Decompressive Craniectomy in Traumatic Brain Injury: Analysis of Risk Factors

Background: The development or expansion of a cerebral hemorrhagic contusion after decompressive craniectomy (DC) for traumatic brain injury (TBI) occurs commonly and it can result in an unfavorable outcome. However, risk factors predicting contusion expansion after DC are still uncertain. The aim of this study was to identify the factors associated with the growth or expansion of hemorrhagic contusion after DC in TBI. Then we evaluated the impact of contusion progression on outcome.Methods: We collected the data of patients treated with DC for TBI in our Center. Then we analyzed the risk factors associated with the growth or expansion of a hemorrhagic contusion after DC.Results: 182 patients (149 males and 41 females) were included in this study. Hemorrhagic contusions were detected on the initial CT scan or in the last CT scan before surgery in 103 out of 182 patients. New or blossoming hemorrhagic contusions were registered after DC in 47 patients out of 182 (25.82%). At multivariate analysis, only the presence of an acute subdural hematoma (p = 0.0076) and a total volume of contusions &gt;20 cc before DC (p = &lt; 0.0001) were significantly associated with blossoming contusions. The total volume of contusions before DC resulted to have higher accuracy and ability to predict postoperative blossoming of contusion with strong statistical significance rather than the presence of acute subdural hematoma (these risk factors presented respectively an area under the curve [AUC] of 0.896 vs. 0.595; P &lt; 0.001). Patients with blossoming contusions presented an unfavorable outcome compared to patients without contusion progression (p &lt; 0.0185).Conclusions: The presence of an acute subdural hematoma was associated with an increasing rate of new or expanded hemorrhagic contusions after DC. The total volume of hemorrhagic contusions &gt; 20 cc before surgery was an independent and extremely accurate predictive radiological sign of contusion blossoming in decompressed patients for severe TBI. After DC, the patients who develop new or expanding contusions presented an increased risk for unfavorable outcome

Isolated cysticercosis of the cauda equina

Cysticercosis is the most common parasitic infection of the central nervous system. It is an endemic condition in developing countries, but the incidence rate is increasing in developed countries as well because of rising immigration. Spinal involvement is quite rare and it is usually associated with concomitant intracranial infective lesions. We present an unusual case of a 44-year-old woman who experienced a cauda equina syndrome. Magnetic resonance imaging disclosed two intradural cystic lesions at L4-L5 level. Only after histological examination the diagnosis of cysticercosis was definitively determined. The entire neuraxis evaluation confirmed that it was a rare form of isolated intradural racemosus type cysticercosis of the cauda equina. Steroids and albendazole were administered and post-operative course was uneventful. In this paper we discuss clinical, pathogenic and therapeutic aspects of this infective pathology

A Case of Nongerminomatous Germ Cell Tumor of the Pineal Region: Risks and Advantages of Biopsy by Endoscopic Approach

A 21-year-old male was admitted to our department with headache and drowsiness. CT scan and MRI revealed acute obstructive hydrocephalus caused by a pineal region mass. The serum and CSF levels of beta-human chorionic gonadotropin (beta-hCG) were 215 IU/L and 447 IU/L, respectively, while levels of alpha-fetoprotein (AFP) were normal. A germ cell tumor (GCT) was suspected, and the patient underwent endoscopic third ventriculostomy (ETV) with biopsy. After four days from surgery, the tumor bled with mass expansion and ETV stoma occlusion; thus, a ventriculoperitoneal shunt was positioned. After ten months, the tumor metastasized to the thorax and abdomen with progression of intracerebral tumor mass. Despite the aggressive nature of this tumor, ETV remains a valid approach for a pineal region mass, but in case of GCT, the risk of bleeding should be taken into account, during and after the surgical procedure

Endoscopic endonasal odontoidectomy with anterior C1 arch preservation in elderly patients affected by rheumatoid arthritis

BACKGROUND CONTEXT: Rheumatoid arthritis is the most common inflammatory disease involving the spine with predilection for the craniovertebral segment. Surgery is usually reserved to patients with symptomatic craniovertebral junction (CVJ) instability, basilar invagination, or upper spinal cord compression by rheumatoid pannus. Anterior approaches are indicated in cases of irreducible ventral bulbo-medullary compression. Classically performed through the transoral approach, the exposure of this region can be now achieved by a minimally invasive endonasal endoscopic approach (EEA). PURPOSE: The aim of this article is to demonstrate the feasibility of performing an odontoidectomy and a rheumatoid pannus removal by a minimally invasive EEA, preserving the anterior C1 arch continuity and avoiding a posterior fixation procedure. STUDY DESIGN: Technical description and cohort report. METHODS: We report three cases of elderly patients with a long history of rheumatoid arthritis and irreducible anterior bulbo-medullary compression secondary to basilar invagination and/or rheumatoid pannus. Anterior decompression was achieved by an endonasal image-guided fully endoscopic approach. RESULTS: Neurological improvement and adequate bulbo-medullary decompression were obtained in all cases. The anterior C1 arch continuity was preserved, and none of the patients required a subsequent posterior fixation. CONCLUSIONS: Anterior decompression by a minimally invasive EEA could represent an innovative option for the treatment of irreducible ventral CVJ lesions in elderly patients with rheumatoid arthritis. This approach permits the preservation of the anterior C1 arch and the avoidance of a posterior fixation, thus preserving the rotational movement at C0-C2 segment and reducing the risk of a subaxial instability development
