OBJECTIVES: To determine the post-operative neurological outcome of intradural spinal tumors in terms of improvement in McCormick classification scheme.METHODOLOGY:  Total of 95 patients diagnosed as case of intradural spinal tumor as per operational definition with any McCormick grade were analyzed. After admission and complete neurological examination, pre-operative McCormik’s grades of each patient were determined and followed for one month after surgery. During their stay they were assessed for neurological improvement as per McCormick grade.RESULTS:There were total 95 patients presenting in OPD with the mean age of 45±12.36 years. There were 42% male and 58% female. There were 62% patients who were improved in neurological outcome while 38% patients were not improved. CONCLUSION:Surgical removal of spinal tumor is beneficial to the affected individual and has positive effect on his life.

OBJECTIVEThe surgical treatment of an upper cervical spinal tumor (UCST) at C1–2/C1–3 is challenging due to anterior exposure and reconstruction. Limited information has been published concerning the effective approach and reconstruction for an anterior procedure after C1–2/C1–3 UCST resection. The authors attempted to introduce a novel, customized, anterior craniocervical reconstruction between the occipital condyles and inferior vertebrae through a modified high-cervical retropharyngeal approach (mHCRA) in addressing C1–2/C1–3 spinal tumors.METHODSSeven consecutive patients underwent 2-stage UCST resection with circumferential reconstruction. Posterior decompression and occiput-cervical instrumentation was conducted at the stage 1 operation, and anterior craniocervical reconstruction using a 3D-printed implant was performed between the occipital condyles and inferior vertebrae via an mHCRA. The clinical characteristics, perioperative complications, and radiological outcomes were reviewed, and the rationale for anterior craniocervical reconstruction was also clarified.RESULTSThe mean age of the 7 patients in the study was 47.6 ± 19.0 years (range 12–72 years) when referred to the authors’ center. Six patients (85.7%) had recurrent tumor status, and the interval from primary to recurrence status was 53.0 ± 33.7 months (range 24–105 months). Four patients (57.1%) were diagnosed with a spinal tumor involving C1–3, and 3 patients (42.9%) with a C1–2 tumor. For the anterior procedure, the mean surgical duration and average blood loss were 4.1 ± 0.9 hours (range 3.0–6.0 hours) and 558.3 ± 400.5 ml (range 100–1300 ml), respectively. No severe perioperative complications occurred, except 1 patient with transient dysphagia. The mean pre- and postoperative visual analog scale scores were 8.0 ± 0.8 (range 7–9) and 2.4 ± 0.5 (range 2.0–3.0; p < 0.001), respectively, and the mean improvement rate of cervical spinal cord function was 54.7% ± 13.8% (range 42.9%–83.3%) based on the modified Japanese Orthopaedic Association scale score (p < 0.001). Circumferential instrumentation was in good position and no evidence of disease was found at the mean follow-up of 14.8 months (range 7.3–24.2 months).CONCLUSIONSThe mHCRA provides optimal access to the surgical field at the C0–3 level. Customized anterior craniocervical fixation between the occipital condyles and inferior vertebrae can be feasible and effective in managing anterior reconstruction after UCST resection.

Abstract BACKGROUND Radical resection is the first-line option in managing cervical primary chondrosarcoma. Favorable anterior reconstruction is challenging after multilevel total spondylectomy in the cervical spine. OBJECTIVE To illustrate the application of piezoelectric surgery and three-dimensional (3D) printing techniques in spine surgery. METHODS A 27-yr-old patient was referred to our center with complaints of nocturnal neck pain and right upper extremity weakness. A 2-stage radical tumor resection was conducted using piezoelectric surgery with pathologically tumor-free margins. A 3D-printed titanium microporous prosthesis (3D-PTMP) was designed to reconstruct the anterior column of the cervical spine between C1 and T1 for stability. RESULTS The whole intraoperative blood loss was 2300 mL over the 2 procedures. The patient had an uneventful recovery, regaining ambulatory status 3 wk after the 2 operations without ventilator support or other severe complications. By the final 14-mo follow-up, the patient had achieved marked pain relief and favorable neurological improvement; a postoperative computed tomography scan indicated a good position of the 3D-printed construct between the endplates with no sign of tumor recurrence or implant subsidence. CONCLUSION The applications of piezosurgery in total spondylectomy and in 3D-PTMP in reconstruction can be a favorable alternative for managing multilevel cervical spinal tumors. Further studies are warranted to validate this surgical strategy.

IgG4-related disease is relatively new disease entity and a rare one, and our knowledge of this entity continues to evolve. It was first described in the pancreas and since then has been described in virtually every organ. Spinal involvement resulting in pachymeningitis is rare, and there are only 8 reported cases of the same to date, with the cervicothoracic spine being the most commonly affected region. The authors describe 2 cases in which the patients presented with spinal compression resulting in myeloradiculopathy (Case 1) and radiculopathy (Case 2). Imaging of spine in both cases revealed an ill-defined contrast-enhancing lesion at the lumbar level. Preoperatively, a diagnosis of spinal tumor was made, but intraoperatively no spinal tumor was found. The diagnosis was established histopathologically. The disease has no particular defining features clinically or radiologically and can mimic common spinal tumors. It is important to accurately diagnose this rare entity because of its multisystem involvement and progressive course. Strict treatment guidelines have yet to be formulated. Although histologically this disease can mimic other inflammatory conditions, the presence of storiform fibrosis and an increased number of IgG4-positive plasma cells can help in clarifying the diagnosis.

Background:Spine tumors remain a hot topic because of their associated morbidity by affecting motor and sensory function. Contrary to metastatic spine disease (MSD), extremely prevalent, rise within or surrounding the spinal cord and/or vertebral column, primary spinal tumors are rare, 5% of all primary skeletal tumors and frequently benign (20%). The diagnostic delay of these tumors, even when benign, is associated with a poor prognosis. Establishing the correct diagnosis is heavily reliant on magnetic resonance imaging and histological confirmation.Objectives:to provide an overview of the epidemiology, radiological and histopathological of spinal tumors diagnosed in a rheumatology department.Methods:A retrospective study consisting of clinical characteristics analysis, laboratory and x-ray examinations, was performed on 40 patients who were hospitalised for a spinal tumor, in a rheumatology department, over 5-year period from 2015 to 2020.Results:A total of 40 patients with a mean age of 66 ± 13.5 years [18-93] and a sex-ratio of 1.1, were included. The most common initial complaints were inflammatory back pain (67.5%) and fatigue (52.5%), with a median duration of 5 months. Physical examination abnormalities included lumbar stiffness (32.5%), radicular signs (18.7%), hepatomegaly (12.5%), and lymphadenopathy (17.5%). Neurological deficit was found in only 3 patients (7.5%). Hypercalcemia (corrected serum calcium > 105 mg/l), and anemia (hemoglobin (Hb) < 100 g/l in female, Hb <110g/l in male) were present initially in respectively 47.5% and 46.3% patients, while biological inflammatory syndrome was present in 89.7% patients (median C-reactive protein of 44.7). Tumor markers were performed in 12 patients and they were positive in 9 of them.Plain radiographs findings were vertebral compression fractures (43.6%), osteolytic lesions (30.8%) and osteoblastic lesions (12.5%). Lumbar spine was the most affected (57.5%), followed by the dorsal spine (45%). Magnetic resonance imaging (MRI) was performed in 55%, and the most common lesion was low signal intensity on T1-weighted sequences and high signal intensity on T2-weighted sequences (68.1%).In our study, only one patient was diagnosed for a myxopapillary ependymoma, a benign primary spinal tumor characterised by a metastatic dissemination risk. For the rest (39 patients), the diagnosis of bone metastasis, multiple myeloma (57.7%), and of solid tumor cancers (40%), were established. Primary cancers were mainly prostate cancer (37.5%), lung cancer (18.7%) and kidney cancer (18.7%). By a median follow-up time of 25 months, overall survival rate was 30%.Conclusion:Extradural lesions are the most common, and are typically metastatic. Special attention should be pain to the patient’s medical history and laboratory abnormalities. In fact, an early diagnosis requires a high index of clinical suspicion.Disclosure of Interests:None declared

Abstract The objective was to test the effect on the immune status by feeding a combination of chicory-plantain and Se-yeast in lactating ewes subjected to intramammary infection (IMI) with 2×107CFU of Strep uberis in both glands. For the purpose we enrolled 28 Polypay lactating sheep from a prior study where they were randomly allocated to receive chicory (CS) or grass (GC) silage and either 3.6 mg of Se/day as Se-yeast (DiaMune, Diamond V) (Y) or isoenergetic-isonitrogenous alfalfa meal (C) for 2 months. For the present study, ewes were kept on the original dietary regiment except the CT group received a chicory-plantain silage(50% each). Blood was collected prior to and for 10 days after IMI for a complete blood count(VetScan HM5), leukocytes migration, and rectal temperature (RT). Data were analyzed using GLIMMIX (SAS)with time, silage type, and Se and their interactions as the fixed effects and ewe as random effect with significance declared at P ≤ 0.05. RT was lower in chicory vs. grass before IMI and Se limited the RT increase after IMI. Total WBC levels tended (P = 0.06) to increase in animals fed with Se after IMI, which was driven by a larger number of lymphocytes. Hematocrit, red blood cells, and hemoglobin were strongly decreased by IMI. The mean cell volume was overall larger in ewes fed with chicory-plantain silage while mean cell hemoglobin was larger in animal fed with grass silage. The platelet distribution width was affected by silage*Se interaction due to a positive effect by Se in grass-fed but negative in chicory-plantain-fed ewes. Migration of neutrophils was larger in animals fed with chicory-plantain before IMI but similar between groups after IMI. Overall, these findings indicate that Se supplementation can increase lymphocytes with no effect on neutrophils while activity of neutrophils is positively affected by feeding chicory-plantain silage.

Purpose. The black iris-lens diaphragm (ILD) can be used in the treatment of traumatic aniridia and aphakia. The aim of our study was to show postoperative functional and anatomic results and complications in a small case series. Methods. We retrospectively analyzed the files of 16 patients managed with a black ILD or a sole iris diaphragm in the period 1994–2007. Four of them were female and 12 were male. The mean age of the group was 50±17 years. At the time of the implantation, all of the eyes had already undergone primary surgical repair. Results. The preoperative best-corrected visual acuity in half of the patients was ≥0.1 and remained stable after the first postoperative year. During the follow-up years, one eye developed a subluxation of the implant and one eye an anterior chamber hemorrhage. At the same time, out of 8 eyes carrying a silicone tamponade in the vitreous cavity, silicone oil entered the anterior chamber in 3 cases. In one case, enucleation was undertaken due to phthisis. Conclusions. In the case of severely traumatized eyes with aniridia and aphakia, the implantation of a black ILD can have a positive effect on functional and anatomic stabilization.

Many epidemiological surveys on playing-related musculoskeletal problems (PRMPs) have been carried out on professional musicians, but none have evaluated or confirmed the psychometric properties of the instruments that were used. The aim of the present study was to evaluate the prevalence of PRMPs among professional orchestra musicians and to gather information on pain intensity and pain interference on function and psychosocial variables, using a self-report instrument developed and validated specifically for a population of professional orchestra musicians. METHODS: Out of 183 professional orchestra players, 101 took part in the study (55% response rate) and completed the Musculoskeletal Pain Intensity and Interference Questionnaire for Musicians (MPIIQM). RESULTS: Lifetime prevalence of PRMPs was 77.2%, 1-year prevalence was 45.5%, and point prevalence was 36.6%. Of the PRMP group, 43% reported having pain in three or more locations, most commonly the right upper limb, neck, and left forearm and elbow. However, predominant sites of PRMPs varied between instrument groups. The mean pain intensity score for the PRMP group was 12.4±7.63 (out of 40). The mean pain interference score was 15.2±12.39 (out of 50), increasing significantly with the number of reported pain locations (F=3.009, p=0.044). CONCLUSION: This study confirms that musculoskeletal complaints are common in elite professional musicians and that the use of an operational definition and a validated self-report instrument allows for more accurate and meaningful estimates of pain prevalence.

This paper aimed to evaluate the effect of preoperative transarterial embolization (TAE) on estimated blood loss (EBL) during surgical excision of the vertebral tumors. Three hundred and forty-eight patients with spinal tumors were retrospectively analyzed. The preoperative TAE group consisted of 190 patients and the control group consisted of 158 patients. Gelatin sponge particles mixed withy contrast agent were used in the TAE group to embolize the tumor-feeding artery. The factors evaluated included: the time interval between embolism and surgery; the number of vertebrae involved by the tumor; pathological type of tumor; surgical approach; extent of excision and instrumental fixation. The time interval (P = 0.4669)between embolism and surgery had no significant correlation with EBL during surgery. The pathological diagnosis of vertebral tumor such as plasma cell myeloma, giant cell tumor, chondrosarcoma, hemangioma and metastasis had no significant correlation with EBL between the TAE group and control group during surgery, while the EBL of chordoma in the TAE group was significantly higher than that in the control group (p = 0.0254). The number of vertebrae involved (p = 0.4669, 0.6804, 0.6677), posterior approach (p = 0.3015), anterior approach (p = 0.2446), partial excision (p = 0.1911) and instrumental fixation (p = 0.1789) had no significant correlation with EBL during surgery between the TAE group and the control group. This study showed that preoperative TAE of the spinal tumor had no significant effect on intra-operative blood loss during surgical excision of the spinal tumor. In view of the risk of embolism, this method should be carefully considered.

Aims To identify the frequency of reports of sporadic schwannomatosis, the types of patients affected, and the nerves affected. Patients and Methods We identified all case reports and case series that reported on patients with sporadic schwannomatosis according to established criteria. Results The initial search yielded 1,597 studies, of which 15 were included. A total of 38 of 55 individuals met the inclusion criteria. The mean age of the patients was 48 years; 41% were male. Thirty-three patients had peripheral nerve tumors, and 17 had spinal tumors. Twelve had tumors in both locations. Tumor distribution was unilateral in 25 of 30 cases (83.3%) and segmental (limited to one limb or five or fewer contiguous segments of the spine) in 28 of 38 cases (73.7%). Conclusion This systematic review quantified the number of individuals who meet the criteria for sporadic schwannomatosis and better described this population to facilitate the classification of neurofibromatosis in regard to the 2005 consensus statement. Unilateral or segmental distribution of nerve tumors are key aspects when dealing with multiple noncutaneous schwannomas without involvement of the vestibular nerve.
