Rare dorsal ossified meningioma in an elderly female: a case report and comprehensive review of literature.

Meningiomas, typically benign neoplasms originating in the central nervous system, display a predilection for female patients. Although they predominantly manifest within the cranial vault, ~25% of primary spinal neoplasms are attributed to these tumors. The occurrence of ossification in spinal meningiomas is an uncommon phenomenon, with scant documentation in medical literature. In this report, we detail the clinical journey of an octogenarian female patient afflicted with an ossified spinal meningioma, which was associated with left lower extremity weakness and reduced sensation. Diagnostic imaging, specifically magnetic resonance imaging, identified a mass exerting pressure on the spinal cord, necessitating its surgical removal. Subsequent histopathological examinations corroborated the initial diagnosis. Postoperative magnetic resonance imaging scans confirmed the absence of residual tumor tissue and ruled out recurrence. A comprehensive review of existing literature yielded 47 analogous cases, with a majority involving elderly female patients and the thoracic region of the spine being the most common site. The standard therapeutic approach is surgical intervention, which is often complicated by the tumor's tenacious adherence to surrounding structures and the potential for ensuing operative complications. This case highlights the exceptional nature of ossified spinal meningiomas and emphasizes the critical need for meticulous surgical management.

Delayed brain abscess as a complication of cerebral infarction: A rare case report and review of the literature.

INTRODUCTION: Systemic infections are a common complication of cerebral stroke, while the development of a cerebral abscess on the background of infarcted brain tissue is an extremely rare occurrence. Here, we present a new case alongside a literature review. CASE PRESENTATION: A previously healthy 37-year-old man presented with sudden right-sided weakness and speech difficulties, progressing to complete aphasia. Initial tests showed no abnormalities, but subsequent CT scans revealed left basal ganglia infarction. Despite treatment and improvement, three months later, his condition worsened, leading to surgical intervention to excision of a cerebral abscess caused by Staphylococcus aureus. Following successful surgery and treatment, the patient showed improvement and was discharged for regular follow-up care. DISCUSSION: The convergence of stroke and brain abscess poses serious clinical challenges, requiring prompt diagnosis and treatment to mitigate catastrophic consequences. Brain abscess, stemming from cerebral infection, may arise from various sources, including contiguous spread, hematogenous dissemination, or traumatic injury. Diagnosis is complicated by nonspecific radiological findings, which often lead to misdiagnosis. Risk factors include age, immunocompromised states, and certain medical conditions. Despite challenges, early detection and appropriate management, involving surgical drainage and antimicrobial therapy, are crucial for favorable outcomes. CONCLUSION: Cerebral abscess following cerebral infarction is rare but should be suspected in patients with prior stroke or hemorrhage, experiencing worsening focal deficits and consciousness. Advanced age and comorbidities increase clinical suspicion.

Mobile schwannoma of the thoracolumbar spine: A case report.

INTRODUCTION: Schwannoma, a benign nerve sheath tumor originating from Schwann cells, can migrate within the spine due to various factors, impacting surgical planning. Unforeseen movement complicates treatment, and it is considered a very rare tumor. CASE PRESENTATION: A 24-year-old woman complained of persistent back pain and was examined at a neurosurgery clinic. Initial MRI found a spinal lesion that later moved, leading to two surgeries. The diagnosis was a Schwannoma, confirmed by examining the tissue under a microscope, showing characteristic features of a Schwannoma, specifically Antoni type A with recent hemorrhage. DISCUSSION: Schwannoma, a rare nerve cell tumor, often migrates within the spine due to its lack of attachment within the dura. The tumor's movement can be triggered by various factors like nerve root laxity, pressure changes, body positioning, or medical procedures. A case study discussed a woman with back pain; her tumor migrated between two MRI scans, showcasing a common migration pattern. Lower back pain commonly manifests as a primary symptom in most cases. Imaging techniques such as myelography and intraoperative ultrasound assist in locating and managing these mobile tumors, advocating for their utilization to minimize surgical complications. CONCLUSION: Reported a rare mobile thoracolumbar schwannoma from nerve sheath cells. Its mobility complicates surgery; precise imaging like intraoperative MRI and ultrasound are crucial for localization, preventing complications.

The effect of teriparatide on patients with atypical femur fractures: a systematic review and meta-analysis.

INTRODUCTION: Bisphosphonates (BPs) are one of the most often used drugs to lower fracture risk in osteoporosis patients; nonetheless, BPs have been linked to atypical femoral fracture (AFF). Teriparatide (TPTD) is a parathyroid hormone analogue and anabolic drug that may accelerate fracture repair. TPTD has been considered as a possible treatment for AFF, particularly those caused by BP use. We evaluate the effect of TPTD on AFF in this systematic review and meta-analysis. MATERIALS AND METHODS: A thorough search of: Web of Science, Scopus, PubMed, and Cochrane was conducted on August 2, 2023. Trials evaluating the effect of TPTD on the incidence of: complete bone healing, non-union, early and delayed bone union, progression of incomplete AFF to complete AFF, and time to bone union were included. Using Review Manager (RevMan) version 5.4, the risk ratio (RR) and mean difference (MD) with the corresponding 95% confidence interval (CI) were estimated for dichotomous and continuous outcomes, respectively. The Newcastle-Ottawa Scale was used to assess the quality of studies. RESULTS: Eight studies met the eligibility criteria and were included in our analysis. TPTD significantly increased the incidence of early bone union (RR = 1.45, 95% CI [1.13, 1.87], P = 0.004) and time to bone union (MD = -1.56, 95% CI [-2.86, -0.26], P = 0.02) compared to the control group. No significant differences were observed in terms of complete bone healing (RR = 1.09, 95% CI [0.99, 1.13], P = 0.12), non-union (RR = 0.48, 95% CI [0.22, 1.04], P = 0.06), and progression of incomplete AFF to complete AFF (RR = 0.27, 95% CI [0.04, 1.97], P = 0.19). CONCLUSIONS: TPTD is an effective therapy for enhancing and hastening healing following AFF, particularly in postoperative settings. Future large randomized clinical trials are needed to confirm or dispute the results.

Efficacy and safety of polyethylene glycol loxenatide in type 2 diabetic patients: a systematic review and meta-analysis of randomized controlled trials.

Polyethylene glycol loxenatide (PEX168) is a novel glucagon-like peptide-1 receptor agonist with a longer half-life developed by modifying the chemical structure of exenatide. This study aims to assess the efficacy and safety of PEX168 and determine the best dose. We searched PubMed, Scopus, Cochrane Library, and Web of Science databases from inception to April 25, 2023, for randomized controlled trials (RCTs) comparing PEX168 therapy alone or in combination with metformin versus other therapies. We used the risk ratio (RR) for dichotomous outcomes and the mean difference (MD) for continuous outcomes, both with 95% confidence intervals (CI). Six RCTs, including 1248 participants, were included. PEX168 added to metformin was significantly better than metformin alone regarding fasting blood glucose (MD = -1.20, 95% CI (-1.78, - 0.62), p < 0.0001), HbA1c (MD = -1.01, 95% CI (-1.48, - 0.53), p < 0.0001), and postprandial glycemia (MD = -1.94, 95% CI (-2.99, - 0.90), p = 0.0003). Similarly, for glycemic control, PEX168 monotherapy was superior to placebo (P < 0.05). No significant effects were noticed in terms of triglycerides, low-density lipoprotein, or high-density lipoprotein (p > 0.05). Body weight was significantly reduced in obese diabetic patients receiving PEX168 compared to the control group (MD = -5.46, 95% CI (-7.90, - 3.01), p < 0.0001) but not in non-obese patients (MD = 0.06, 95% CI (-0.47, 0.59), p = 0.83). People who received PEX168 alone or with metformin showed more common gastrointestinal adverse effects, especially nausea and vomiting (p < 0.05). PEX168 100, 200, and 300 ug monotherapy demonstrated comparable safety and diabetes control to metformin, but when combined with metformin, PEX168 100 and 200 ug showed significant effects on diabetes control; however, only the latter showed a significantly higher incidence of nausea and vomiting (p < 0.05). PEX168 could be a viable option for treating diabetic patients whose metformin control is inadequate or who cannot tolerate metformin. PEX168 at 100 ug in combination with metformin was found to be safe and more effective compared to metformin; however, due to the small number of trials included, these findings should be interpreted with caution, and additional trials are required.

The effects of acupressure on postoperative nausea and vomiting among patients undergoing laparoscopic surgery: A meta-analysis of randomized controlled trials.

BACKGROUND AND OBJECTIVE: Laparoscopic surgery is one of the most commonly performed surgeries in general surgery, with fewer side effects and rapid recovery. Postoperative nausea and vomiting (PONV) remains the main challenge that confronts the prognosis of this minimally invasive surgery. We aimed to evaluate the effect of acupressure, a nonpharmacological non-invasive method, on the incidence of nausea and vomiting following laparoscopic surgery within the early phase (first six hours postoperatively) and the extended phase (for at least 24 h postoperatively). METHODS: We searched PubMed, Cochran, Scopus, Web of Science, Google scholar, and Wiley for randomized controlled trials that evaluated the effect of acupressure on PONV in patients undergoing laparoscopy. Data were extracted and analyzed in a random model, and pooled risk ratios (RRs) with their respective 95% confidence intervals (CIs) were calculated. RESULTS: Eleven trials were included in the meta-analysis, comprising 941 patients. Most of the included patients were females undergoing gynecological laparoscopy or laparoscopic cholecystectomy. Acupressure significantly lowered the incidence of nausea and vomiting, within the early phase (RR = 0.62, 95% CI [0.44 to 0.88]; p = 0.008), (RR = 0.5, 95% CI [0.30 to 0.84]; p = 0.008), and the extended phase (RR = 0.65, 95% CI [0.52 to 0.83]; p = 0.0003), (RR = 0.44, 95% CI [0.32 to 0.61]; p < 0.00001), respectively. Moreover, acupressure significantly reduced the need for rescue antiemetic drugs in both phases (p < 0.05). CONCLUSION: Acupressure is an effective procedure for reducing nausea, vomiting, and the need for antiemetic drugs after laparoscopic surgery.
