Bilateral spheno-orbital meningiomas: surgical management, progression, and recurrence.

OBJECTIVE: Bilateral spheno-orbital meningiomas (bSOMs) are a rare entity among meningiomas. These tumors are benign and predominantly affect women. They represent 4% of spheno-orbital meningiomas (SOMs) and are poorly described in the literature. This study aimed to describe the characteristics, risk factors, evolution, and management of bSOMs. METHODS: Twenty patients with bSOMs were enrolled in a multicentric descriptive study including 15 neurosurgical departments. RESULTS: In this study, the authors found that bSOMs affected exclusively women, with a mean age of 50 years. Approximately 65% of patients were on progestin therapy. The mean follow-up in this series was 55 months. Clinically, visual symptoms were predominant: proptosis was present in 17 of 20 patients (85%; 7 unilateral, 10 bilateral), and a decrease in visual acuity was observed in 11 of 20 patients (55%; 6/10 to 9/10 in 6 patients, 3/10 to 5/10 in 1 patient, and < 3/10 in 4 patients). Contrary to unilateral SOMs, the authors identified that intracranial hypertension was a common presentation (25%) of bSOMs. Surgical management with gross-total resection was the gold standard treatment. Recurrences only occurred following subtotal resection in 36% to 60% of patients, with a median time of 50 to 54 months after surgery. Visual improvement or stability was observed in 75% of cases postoperatively. Progesterone receptor expression levels were 70% to 100% in 10 of 11 (91%) cases. CONCLUSIONS: Bilateral SOMs are usually found in female patients and are strongly associated with hormone replacement therapy. Early surgical management with gross-total resection is the most effective treatment in terms of recurrence and improves visual acuity. Given the slow progressive nature of bSOMs and their time to recurrence, which can be up to 10 years, long-term follow-up of patients is essential.

Are there Still any Benefits to Drainage for Anterior Cervical Arthrodesis/Arthroplasty by Cervicotomy?

STUDY DESIGN: A retrospective single-center study between January 2019 and 2023. OBJECTIVE: The role and contribution of drainage in the anterior approach to the cervical spine (cervicotomy) is much debated, motivated primarily by the prevention of retropharyngeal hematoma, so are there still any benefits to drainage? BACKGROUND: The anterior approach to the cervical spine is a widespread and common procedure performed in almost all spine surgery departments for the replacement of cervical intervertebral discs and medullar or radicular decompression. The primary endpoint was the occurrence of symptomatic postoperative cervical hematoma. METHODS: Four hundred thirty-one patients who had undergone cervical spine surgery by anterior cervicotomy for cervicarthrosis or cervical disc herniation (ACDF, ACDR) were consecutively included. Patients were separated into 2 groups: Group A, 140 patients (with postoperative drainage) and group B, 291 patients (without drainage). RESULTS: Mean follow-up was 2.8 months. The 2 groups were comparable on all criteria, but there was a predominance of arthroplasty (P<0.0001), use of anticoagulants/antiaggregants (P<0.0001) and a greater number of stages (P<0.0001) in group A. There were a total of 4/431 symptomatic postoperative hematomas (0.92%) in this study. Two hematomas occurred in group A (2/140, 1.4%) and two in group B (2/291, 0.68%) (P<0.0001). One patient in group A (0.71%) required surgical drainage for cavity hematoma revealed by marked dyspnea, swallowing and neurological disorders. One case of hematoma diagnosed by dysphonia and neurological deficit was reported in group B (0.34% (P<0.0001). CONCLUSIONS: Placement of a drain during anterior cervicotomy for (ACDF/ACDR) did not limit the occurrence of symptomatic postoperative hematoma.

Impact of metastatic epidural spinal cord compression (MESCC) and pathological vertebral compression fracture (pVCF) in neurological and survival prognosis.

BACKGROUND: Metastatic epidural spinal cord compression (MESCC) and pathological vertebral compression fractures (pVCF) are the most serious debilitating morbidities of spine metastases (SpMs) causing devastating neurological damages. The respective impact of these two metastasis-spreading entities on survival and on neurological damage is debated. METHODS: A French prospective cohort study collected 279 consecutive patients presenting with SpMs between January 2017 and 2021. We compared 174 patients with MESCC and 105 patients with pVCF. RESULTS: The median Overall Survival (OS) for the MESCC group was 13.4 months (SD 1.5) vs 19.2 months (SD 2.3) for pVCF patients (p = 0.085). Sixty-five patients (23.3 %) were operated on: 49/65 (75.4 %) in the MESCC group and 16/65 (15.2 %) in the pVCF group, p < 0.0001. At 6 months FU, in the MESCC group, 21/44 (45.4 %) of non-ambulatory patients at onset improved to ambulatory status (Frankel D-E) vs 10/13 (76.9 %) in the pVCF group (p = 0.007). In multivariable analysis with the Cox proportional hazard model, good ECOG-PS and SINS Score 7-12 [HR: 6.755, 95 % CI 2.40-19.00; p = 0.001] were good prognostic factors for preserved ambulatory neurological status. However, SpMs diagnosed synchronously with the primary tumor [HR: 0.397, 95 % CI 0.185-0.853; p = 0.018] and MESCC [HR: 0.058, 95 % CI 0.107-0.456; p = 0.007] were independent risk factors for impaired neurological function. CONCLUSION: Contrary to pVCF, MESCC causes neurological damage. Nevertheless, neurological recovery remains possible. MESCC and pVCF have no impact on survival. The management of MESCC remains to be clarified and optimized to reduce neurological damage.

Multiple Myeloma Spinal Lesion Care: Management of a Primary Bone Malignancy Rather Than a Spinal Metastasis.

OBJECTIVE: Multiple myeloma (MM) is too often wrongly categorized as a spinal metastasis (SpM), although it is distinguishable from SpM in many aspects, such as its earlier natural history at the time of diagnosis, its increased overall survival (OS), and its response to therapeutic modalities. The characterization of these 2 different spine lesions remains a main challenge. METHODS: This study compares 2 consecutive prospective oncologic populations of patients with spine lesions: 361 patients treated for MM spine lesions and 660 patients treated for SpM between January 2014 and 2017. RESULTS: The mean time between the tumor/MM diagnosis and spine lesions was respectively 0.3 (standard deviation [SD] 4.1) and 35.1 months (SD 21.2) for the MM and SpM groups. The median OS for the MM group was 59.6 months (SD 6.0) versus 13.5 months (SD 1.3) for the SpM group (P < 0.0001). Regardless of Eastern Cooperative Oncology Group (ECOG) performance status, patients with MM always have a significantly better median OS than do patients with SpM: ECOG 0, 75.3 versus 38.7 months; ECOG 1, 74.3 versus 24.7 months; ECOG 2, 34.6 versus 8.1 months; ECOG 3, 13.5 versus 3.2 months and ECOG 4, 7.3 versus 1.3 months (P < 0.0001). The patients with MM had more diffuse spinal involvement (mean, 7.8 lesions; SD 4.7) than did patients with SpM (mean, 3.9; SD 3.5) (P < 0.0001). CONCLUSIONS: MM must be considered as a primary bone tumor, not as SpM. The strategic position of the spine in the natural course of cancer (i.e., nurturing cradle of birth for MM vs. systemic metastases spreading for SpM) explains the differences in OS and outcome.

Spinal lesions in multiple myeloma: Primary bone tumors with distinct prognostic factors.

PURPOSE: Although prognostic factors of spinal multiple myeloma (MM) seem to differ from those of other spine metastases (SpM), the data in the literature remains scarce. METHODS: A prospective population of 361 patients treated for spine MM lesions between January 2014 and 2017. RESULTS: OS for our series was 59.6 months (SD 6.0 months; CI 95%: 47.7-71.3). Cox multivariate proportional-hazards analysis showed that bone marrow transplant [HR: 0.390, 95% CI 0.264-0.577; p < 0.0001] and light-chain isotype [HR: 0.748, 95% CI 0.318-1.759; p = 0.005] were independent predictors of longer survival. In contrast, age >80 years [HR: 2.7, 95% CI 1.6-4.3; p < 0.0001], ISS III [HR: 2.510, 95% CI 2.01-3.124; p = 0.001], IgA isotype [HR: 1.475, 95% CI 1.031-2.11; p = 0.034] and IgD/M isotype [HR: 2.753, 95% CI 1.230-6.130; p = 0.013] were independent poor prognostic factors. However, ECOG (p = 0.486), spine surgery (p = 0.391), spine radiotherapy (p = 0.260), epidural involvement (p = 0.259), the number of vertebra lesions (p = 0.222), and synchronous/metachronous timeline (p = 0.412) were not significantly associated with improved OS. CONCLUSIONS: Spinal involvement in the context of MM does not influence OS. The main prognostic factors to consider before spinal surgery are the characteristics of the primary MM disease (ISS score, IgG isotype and systemic treatment).

Spine Metastasis: Patients With Poor Performance Status (ECOG) Could benefit From Palliative Surgical Care! A Prospective Cohort Study.

STUDY DESIGN: This study used a French prospective national multi-center database of patients with spine metastasis (SpM). OBJECTIVE: The main challenge was to clarify if SpM patients presenting poor ECOG-PS could benefit from a surgical intervention. BACKGROUND: Spine metastases (SpM) are debilitating lesions commonly found in the evolution of cancer. At present, patients with poor ECOG-PS do not benefit from surgical care. MATERIALS AND METHODS: Between 2014 and 2017, 176 SpM patients with poor initial ECOG-PS (3 or 4) were identified. RESULTS: The median overall survival of patients was 2.1 months (SD 0.2). Seventy-one patients (40.3%) underwent surgery: for 49 patients (27.8%) the intervention consisted of a simple decompression and for 22 patients (12.5%) the previous was associated with an osteosynthesis. Patients who underwent surgery demonstrated significantly longer median overall survival than those who did not: 3.5 months (SD 0.4) versus 1.6 (SD 0.2) ( P <0.0001). No significant differences between operated/nonoperated patients were noted concerning median age (66.4 vs. 64.2 y, P =0.897), the median number of SpM (4.1 vs. 4.2, P =0.374), ECOG-PS 4 ratio (41.6 vs. 39.3%, P =0.616), or for primary tumors ( P =0.103). Patients who underwent surgery statistically improved their neurological impairment according to the Frankel score: 5/11 (45.4%) from A to C, 5/17 (29.4%) from B to C or D, 6/11 (54.5%) from C to D and 2/4 (50%). Twelve patients (16.9%) presented a postoperative complication. CONCLUSION: Patients with poor ECOG-PS could benefit from surgery. Even though survival gain is small, it permits the preservation of their neurological function. By making ambulation possible, pain is decreased during the last months of their lives.

One-year all-cause mortality in hospitalized patients with COVID-19 and end-stage renal disease undergoing hemodialysis.

INTRODUCTION: Patients with end-stage renal disease (ESRD) on dialysis and COVID-19 infection have an increased risk of in-hospital mortality, but whether these patients have a higher long-term mortality risk is unknown. MATERIALS AND METHODS: Retrospective chart review of 958 patients admitted with COVID-19 infection or those with ESRD admitted for any other reason between February 2020 and August 2020. We collected data on demographics, comorbidities, laboratory tests, and mortality. The primary outcome was all-cause 1-year mortality. The secondary outcome was in-hospital mortality. We used primarily logistic regression models to assess the mortality risk. RESULTS: In total, 651 patients without ESRD with COVID-19 (COVID+ESRD-), 259 with ESRD without COVID-19 (ESRD+COVID-), and 48 with ESRD with COVID-19 (COVID+ESRD+) were hospitalized between February 2020 and August 2020. Patients were followed after discharge until September 2021. The all-cause 1-year mortality rates were 24% in patients with COVID+ESRD-, 22% in ESRD+COVID- patients, and 40% in those with COVID+ESRD+ (p < 0.05). Compared to the COVID+ESRD- group, the unadjusted and adjusted odds ratio (OR) for all-cause 1-year mortality in the COVID+ESRD+ group was 2.13 (95% confidence interval (CI), 1.16 - 3.91) and 2.15 (95% CI,1.12 - 4.14), respectively. The unadjusted and adjusted OR for all-cause in-hospital mortality in the COVID+ESRD+ group was 1.79 (95% CI, 0.92 - 3.49); and 1.79 (95% CI, 0.88 - 3.65), respectively. We found no statistically significant difference between the COVID+ESRD- and ESRD+COVID- groups for both in-hospital and 1-year mortality (p > 0.05). CONCLUSION: Patients with COVID+ESRD+ have significantly higher odds for all-cause 1-year mortality compared to COVID+ESRD- patients. Future studies should investigate the mechanisms of long-term mortality risk in ESRD patients with COVID-19 infection.

Chronic low back pain during COVID-19 lockdown: is there a paradox effect?

PURPOSE: The coronavirus 2019 (COVID-19) pandemic led to a compulsory lockdown of 3 months with strict restrictions. The impact of the COVID-19 pandemic has shown broad repercussions on patients with chronic pain; especially for conditions that present a significant emotional participation such as chronic low back pain (cLBP). METHODS: We performed a prospective study on 50 patients. Pre- and 1-month post-lockdown questionnaires such as: the Impact of Event Scale (IES), the Oswestry Disability Index (ODI), the Roland-Morris questionnaire (RMQ) and the visual analogue scale (VAS) for back and leg pain intensity were collected. RESULTS: The mean time of the evolution of cLBP was 33.04 months (range 5-120 months). Eighteen (36%) patients improved their cLBP (i-cLBP), whereas for 14 (28%) it was worse (w-cLBP). Cox multivariate proportional hazard model identified that MODIC 1 disc disease [OR 19.93, IC95% (2.81-102.13), p = 0.015] and at-home workouts [OR 18.854, IC95% (1.151-204.9), p = 0.040] were good prognosis factors of the improvement of cLBP while subclinical/mild Covid-19 anxiety (IES score < 26) was a poor prognosis factor in improving cLBP [OR 0.21, IC95% (0.001-0.384), p = 0.009]. Furthermore, pre-lockdown benzodiazepine medication [OR 2.554, IC95% (1.20-9.9), p = 0.002] was a prognosis factor of worse cLBP. In contrast, patients with severe Covid-19 anxiety (IES score > 26) significantly improved their cLBP [OR 0.58, IC95% (0.025-0.834), p = 0.01]. CONCLUSION: Lockdown affected the somatic component of cLBP by decreasing activities and physical measures, whereas the SARS-CoV-2 pandemic spectrum paradoxically improved the psychic and emotional component of cLBP.

Cauda Equina Syndrome: Poor Recovery Prognosis Despite Early Treatment.

STUDY DESIGN: A prospective patient's database operated on a cauda equina syndrome (CES). OBJECTIVE: The aim of our study was to identify prognosis factors for favorable functional recovery after CES. SUMMARY OF BACKGROUND DATA: CES is a neurologic impairment of variable symptoms associating urinary, bowel, and sexual dysfunctions with or without motor or sensitive deficits caused by nerve root compression of the cauda equina. The definition of CES remains debated, as well as the prognosis factors for favorable functional recovery and the benefit of early surgery. METHODS: One hundred forty patients were included between January 2010 and 2019. Univariate and multivariate cox proportional hazard regression models were conducted. RESULTS: The patients were young with a median age of 46.8 years (range 18-86 yrs). At presentation, 60% were affected by a motor deficit, 42.8% a sensitive deficit, 70% urinary dysfunctions, and 44% bowel dysfunctions. The mean follow-up was 15.5 months. Bilateral motor deficit (P = 0.017) and an initial deficit severity of 0 to 2 (P = 0.001) represented prognosis factors of poor motor recovery. Initial anal incontinence (P = 0.007) was associated with poor bowel recovery. Only 32.8% of the patients went back to work. Initial motor deficit (P = 0.015), motor sequelae (P = 0.001), sphincter dysfunctions sequelae (P = 0.02), and long LOS (P = 0.02) were poor return-to-work prognosis factors. Time to surgery within an early timing < 24 or 48 hours or later did not represent a prognosis factor of recovery in CES. Incomplete versus complete CES did not show better recovery. CONCLUSION: CES remains a profound disabling syndrome with poor functional prognosis: in the long run, few patients go back to work. The main prognosis factors established in our series regarded the initial severity of deficits whether motor or sphincteral. Early or later surgical cauda equina decompression did not show to represent a prognosis factor for functional recovery.Level of Evidence: 4.

Linking mobile money networks to "e-ROSCAs": An experimental study.

We present results from a study in the Democratic Republic of the Congo that uses mobile money networks to run rotating savings and credit associations (ROSCAs), peer-to-peer finance groups ubiquitous across the developing world. We find high rates of contribution and ROSCA success. The unexpected success of such e-ROSCAs and their potential to extend banking to the bankless poor necessitate further exploration.

Arcuate foramen: "Anatomical variation shape or adaptation legacy?"

PURPOSE: The groove of the vertebral artery on the posterior arch of the atlas (sulcus arteriae vertebralis) may become a complete or partial osseous foramen: the arcuate foramen. The presence of a complete or partial arcuate foramen is a rare anatomical variant described in a minority of patients and it seems to be associated with vertigo, vertebro-basilar insufficiency, posterior circulation strokes, and musculoskeletal pain. As the number and morphology of cervical vertebrae is highly preserved, we questioned about its significance from an evolutionary point of view. We thus investigated through an extensive literature review if the arcuate foramen is a pure anatomical variation shape or if it might represent an adaptation legacy. METHODS: We observed five atlas of an extinct species, the Late Pleistocene Mammoths (M. primigenius), and we compared them with five atlas of a closely related existent species, the African elephant (L. africana). RESULTS: All the mammoths' atlas had an arcuate foramen through which the vertebral artery passed before turning anteriorly and becoming intradural. This foramen was not present in elephants' atlas, where only a groove was observed, such as in the majority of patients. CONCLUSION: We would like to raise the hypothesis that this peculiar morphology of mammoths' atlas might have contributed, in association with other factors, to their precocious extinction and that the arcuate foramen might represent a disadvantage in the evolutionary process, with a low prevalence in humans being the result of a natural selection.

Peritumoral Edema/Tumor Volume Ratio: A Strong Survival Predictor for Posterior Fossa Metastases.

BACKGROUND: Twenty percent of all brain metastases (BM) occur in the posterior fossa (PF). Radiotherapy sometimes associated with surgical resection remains the therapeutic option, while Karnovsky performance status and graded prognostic assessment (GPA) are the best preoperative survival prognostic factors. OBJECTIVE: To explore the prognostic role of peritumoral brain edema in the PF, which has never been explored though its role in supratentorial BM has been debated. METHODS: A total of 120 patients diagnosed with PF metastasis who underwent surgical resection were included retrospectively in this analysis. Clinical data were retrieved from electronic patient medical files. The tumor volumes and their associated edema were calculated via manual delineation; subsequently the edema/tumor volume ratio was determined. RESULTS: In multivariate analysis with Cox multivariate proportional hazard model, the edema to tumor volumes ratio (hazard ratio [HR]: 1.727, 95% confidence interval [CI] 1.427-2.083; P < .0001) was identified as a new strong independent prognosis factor on overall survival (OS) whereas edema volume alone was not (P = .469). Moreover, BM complete resection (HR: 0.447, 95% CI 0.277-0.719; P < .001), low (0-1) World Health Organization status at diagnosis (HR: 2.109, 95% CI 1.481-3.015; P < .0001), high GPA class at diagnosis (HR: 1.77, 95% CI 0.9-2.9; P < .04), and postoperative brain irradiation (HR: 2.019, 95% CI 1.213-3.361; P < .007] were all confirmed as independent predictive factors for survival. CONCLUSION: The edema/tumor ratio appears to greatly influence OS in patients suffering from PF metastases unlike the extent of edema alone. This easily determined as well as strong prognostic factor could be used as an interesting tool in clinical practice to help the management of these patients.

Sex-Related Differences in Lactotroph Tumor Aggressiveness Are Associated With a Specific Gene-Expression Signature and Genome Instability.

Sex-related differences have been reported in various cancers, in particular men with lactotroph tumors have a worse prognosis than women. While the underlying mechanism of this sexual dimorphism remains unclear, it has been suggested that a lower estrogen receptor alpha expression may drive the sex differences observed in aggressive and malignant lactotroph tumors that are resistant to dopamine agonists. Based on this observation, we aimed to explore the molecular importance of the estrogen pathway through a detailed analysis of the transcriptomic profile of lactotroph tumors from 20 men and 10 women. We undertook gene expression analysis of the selected lactotroph tumors following their pathological grading using the five-tiered classification. Chromosomic alterations were further determined in 13 tumors. Functional analysis showed that there were differences between tumors from men and women in gene signatures associated with cell morphology, cell growth, cell proliferation, development, and cell movement. Hundred-forty genes showed an increased or decreased expression with a minimum 2-fold change. A large subset of those genes belonged to the estrogen receptor signaling pathway, therefore confirming the potent role of this pathway in lactotroph tumor sex-associated aggressiveness. Genes belonging to the X chromosome, such as CTAG2, FGF13, and VEGF-D, were identified as appealing candidates with a sex-linked dysregulation in lactotroph tumors. Through our comparative genomic hybridization analyses (CGH), chromosomic gain, in particular chromosome 19p, was found only in tumors from men, while deletion of chromosome 11 was sex-independent, as it was found in most (5/6) of the aggressive and malignant tumors. Comparison of transcriptomic and CGH analysis revealed four genes (CRB3, FAM138F, MATK, and STAP2) located on gained regions of chromosome 19 and upregulated in lactotroph tumors from men. MATK and STAP2 are both implicated in cell growth and are reported to be associated with the estrogen signaling pathway. Our work confirms the proposed involvement of the estrogen signaling pathway in favoring the increased aggressiveness of lactotroph tumors in men. More importantly, we highlight a number of ER-related candidate genes and further identify a series of target molecules with sex-specific expression that could contribute to the aggressive behavior of lactotroph tumors in men.

The origins of human prosociality: Cultural group selection in the workplace and the laboratory.

Human prosociality toward nonkin is ubiquitous and almost unique in the animal kingdom. It remains poorly understood, although a proliferation of theories has arisen to explain it. We present evidence from survey data and laboratory treatment of experimental subjects that is consistent with a set of theories based on group-level selection of cultural norms favoring prosociality. In particular, increases in competition increase trust levels of individuals who (i) work in firms facing more competition, (ii) live in states where competition increases, (iii) move to more competitive industries, and (iv) are placed into groups facing higher competition in a laboratory experiment. The findings provide support for cultural group selection as a contributor to human prosociality.

Therapeutic Failure in Trigeminal Neuralgia: from a Clarification of Trigeminal Nerve Somatotopy to a Targeted Partial Sensory Rhizotomy.

BACKGROUND: Trigeminal neuralgia (TN) is a severe unilateral facial pain involving 1 or more branches of the trigeminal nerve (CNV). Microvascular decompression is a standard curative treatment of pharmacoresistant classic TN. Alternative procedures used for secondary or idiopathic TN usually lead to a high rate of pain recurrence and sensitive deficits. Partial sensory rhizotomy (PSR) is one of these ablative procedures. However, the lack of anatomic knowledge about the somatotopy of CNV lead to variable results in pain relief and hypoesthesia. OBJECTIVE: To refine the somatotopy of CNV and bring new anatomic landmarks for PSR, studying a cohort of patients treated by a targeted PSR (TPSR). METHODS: Retrospective and consecutive cases of adult patients treated in our institution between March 2000 and June 2015 for pharmacoresistant TN without vascular compression were collected. Our surgical procedure was performed using a precision map of the somatotopy of CNV. We compared our results with other surgical and nonsurgical therapies. RESULTS: Twenty-two patients had undergone TPSR. Fourteen had an idiopathic TN without compression of the nerve root, 6 had a secondary TN caused by multiple sclerosis, and 2 had a trigeminal conflict by inoperable tumor. Complete pain relief was achieved in 86.4% of the patients. Postoperative hypoesthesia was partial and focalized (22.7%). TN recurrence rate at 5 years was 31.5% (standard deviation, 10.9%). CONCLUSIONS: We clarified the functional somatotopy of CNV in its juxtapontine portion. TPSR is an interesting alternative to other ablative procedures to treat pharmacoresistant TN without vascular compression.

Spinal metastases in multiple myeloma: A high-risk subgroup for ISS III patients.

BACKGROUND: Patients with multiple myeloma (MM) have an extremely heterogeneous prognosis. The International Staging System (ISS) is actually the most reliable staging system and chromosomal abnormalities were integrated in the Revised-ISS. We wanted to evaluate the prognostic value of spinal secondary localization in patients with MM and its impact on the ISS. METHODS: Epidemiological and biological data, as well as treatment protocols and secondary localization were analyzed for 650 consecutive patients diagnosed with MM from January 2006 to January 2017. RESULTS: The overall survival (OS) was dependent on the WHO performance status, ISS and Salmon and Durie stage at diagnosis. Furthermore, presence of spinal metastases at diagnosis was predictive of a worse outcome (p < 0.0001), while presence of peripheral bone metastases was not. Spinal metastases had a significant impact on OS for ISS III patients (p < 0.0001). Also, a history of bone marrow graft was associated with a better OS (p < 0.0001), while radiotherapy had no significant impact. The multivariate analysis confirmed that the spinal metastases at diagnosis determined a high-risk subgroup for ISS III patients with a very poor OS (p < 0.0001). CONCLUSIONS: Spinal metastases are a negative prognostic factor for patients with MM, especially for ISS III patients, and are associated with a shorter OS. Spinal metastasis should be systemically searched for and should be included in a modified staging system to better manage these patients.

The Socioeconomic Implications of Isolated Tibial and Femoral Fractures from Road Traffic Injuries in Uganda.

BACKGROUND: The purpose of this study was to determine the socioeconomic implications of isolated tibial and femoral fractures caused by road traffic injuries in Uganda. METHODS: This prospective longitudinal study included adult patients who were admitted to Uganda's national referral hospital with an isolated tibial or femoral fracture. The primary outcome was the time to recovery following injury. We assessed recovery using 4 domains: income, employment status, health-related quality of life (HRQoL) recovery, and school attendance of the patients' dependents. RESULTS: The majority of the study participants (83%) were employed, and they were the main income earner for their household (74.0%) at the time of injury, earning a mean annual income of 2,375 U.S. dollars (USD). All of the patients had been admitted with the intention of surgical treatment; however, because of resource constraints, only 56% received operative treatment. By 2 years postinjury, only 63% of the participants had returned to work, and 34% had returned to their previous income level. Overall, the mean monthly income was 62% less than preinjury earnings, and participants had accumulated 1,069 USD in debt since the injury; 41% of the participants had regained HRQoL scores near their baseline, and 62% of school-aged dependents, enrolled at the time of injury, were in school at 2 years postinjury. CONCLUSIONS: At 2 years postinjury, only 12% of our cohort of Ugandan patients who had sustained an isolated tibial or femoral fracture from a road traffic injury had recovered both economically and physically. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Sphenoid Mucocele with Intracranial Extension: An Anatomic Perspective.

BACKGROUND: Isolated sphenoid mucoceles are rare, but because of their close proximity to important vasculonervous structures, local extension may result in serious consequences. CASE DESCRIPTION: A 47-year-old patient presented with headaches, meningismus, and a left homonymous lateral hemianopia. We report the atypical evolution of a posttraumatic sphenoid mucocele invading the sellar region and extending into the subarachnoid space with compression of the right optic tract, and we describe its surgical management. Further, with the aid of cadaveric specimens, we aim to analyze the precise pathway followed by the expanding collection from an anatomic perspective. CONCLUSIONS: Anatomic knowledge of the sellar and parasellar regions is the key to understand the process of how sphenoid mucoceles may extend intracranially. Early endoscopic drainage with a large sphenoidotomy allows favorable outcomes and prevents serious consequences.

Spheno-Orbital Meningiomas Surgery: Multicenter Management Study for Complex Extensive Tumors.

BACKGROUND: Spheno-orbital meningiomas (SOMs) are complex tumors involving the sphenoid wing, the orbit, and sometimes the cavernous sinus with bone hyperostosis and sheet-like dural involvement. Optimal removal, proptosis cure, and visual preservation remain a challenge. OBJECTIVE: To study the management of surgically treated SOMs. METHODS: The clinical records of 130 consecutive patients undergoing surgery for SOMs were retrospectively collected in a database during a 20-year period to analyze symptoms, surgical technique, clinical outcome, and follow-up. RESULTS: Among the 130 patients (mean age 51.2 ± 9.5 years), 91.5% were female. The most typical symptoms recorded were proptosis in 94.6%, visual impairment in 37.7%, and oculomotor paresis in 10.0%. Simpson grade I-II removal was achieved in 97 patients (74.6%). After 1 year, proptosis was improved in 60% of cases. A total of 44.9% of the patients with preoperative visual acuity impairment were improved. Periorbital excision was statistically linked to proptosis decreasing (P = 0.0001) and optic canal decompression was linked to visual stabilization (P = 0.03). Bone reconstruction prevented temporal muscle atrophy (P = 0.01) and unaesthetic results (P = 0.0001). Mean follow-up was 76.5 months (range 3-288 months), and the mean time for recurrence was 54.2 months. CONCLUSIONS: A single-stage optimal surgery with bone reconstruction appears to be the best first-line treatment, on a case-by-case analysis. Optic canal decompression and periorbital excision have to be performed in case of visual disturbance and proptosis. SOMs require a long-term follow-up because of a delayed high rate of recurrence.
