BACKGROUND: Patients with giant intracranial aneurysms (GIAs) are at a high risk of rupture, morbidity, and mortality even after surgical or endovascular treatment. We described a case of a spontaneously occluded GIA secondary to gradual growth of the GIA, continuously progressed aneurysmal thrombosis, complete aneurysmal calcification and complete occlusion of the parent artery-the right internal carotid artery (RICA).
METHODS: A 72-year-old female patient complained of sudden pain in her right eye upon admission to our hospital. She had been diagnosed with a GIA [30 mm (axial) × 38 mm (coronal) × 28 mm (sagittal)] containing an aneurysmal thrombus located in the cavernous sinus segment of RICA diagnosed by magnetic resonance imaging (MRI), enhanced MRI, and magnetic resonance angiography more than 14 years ago. Later, with slow growth of the cavernous carotid GIA, aneurysmal thrombosis progressed continuously, spontaneous occlusion of the RICA, complete aneurysmal calcification, and occlusion of the GIA occurred gradually. She had no history of subarachnoid hemorrhage but missed the chance for endovascular therapy at an early stage. As a result, she was left with severe permanent sequelae from the injuries to the right cranial nerves II, III, IV, V1/V2, and VI.
CONCLUSIONS: The risk of rupture of the cavernous carotid GIAs was relatively low and possibly further be reduced by the stasis flow and spontaneous occlusion of the parent artery internal carotid artery (ICA) induced by the mass effect of the cavernous carotid GIAs and the extremely rare aneurysmal calcification. However, nowadays, it is advisable to recommend early endovascular treatment for the cavernous carotid GIAs to prevent injuries to the surrounding intracranial nerves and occlusion of the ICA, mainly caused by the mass effect of the cavernous carotid GIAs.

BACKGROUND: Our objective was to conduct a systematic review and meta-analysis of studies evaluating the oncological and reproductive outcomes of patients with endometrial atypical hyperplasia (AH) and endometrioid endometrial cancer (EEC) undergoing conservative therapy with hysteroscopic resection (HR).
METHODS: This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement for systematic reviews and meta-analyses. The study strictly followed the methodological framework proposed by the Cochrane Handbook and was retrospectively registered in PROSPERO (CRD42023469986). Searches were conducted in PubMed, Embase, and the Cochrane Library, from inception to October 10, 2023. A checklist based on items of the Newcastle-Ottawa Scale and the Methodological Index for Non-randomized Studies was used for quality assessment. The primary end points for this meta-analysis were complete response (CR), pregnancy, and live birth rates following HR-based therapy in patients with EEC or AH. The secondary end point was the recurrence rate (RR).
RESULTS: Twenty-one articles involving 407 patients with clinical stage IA, low or intermediate grade, EEC, and 444 patients with AH managed with HR-based conservative treatment were included for this systematic review. CR to HR-based conservative therapy was achieved in 88.6% of patients with EEC and 97.0% of patients with AH. Of these, 30.6% and 24.2%, respectively, had live births. The overall pooled disease RR was 18.3% and 10.8% in patients with EEC and AH, respectively. Further subset analyses revealed that EEC patients with body mass index (BMI) ≤28 kg/m2 had higher CR rates as well as higher chances of pregnancy and live birth (91.6% CR, 32.9% pregnancy, 31.1% live birth) compared with patients with BMI >28 kg/m2 (86.4% CR, 28.4% pregnancy, 23.0% live birth). The HR followed by oral progestogen subgroup had higher CR rates and higher chances of pregnancy and live birth (91.8% CR, 36.3% pregnancy, 28.2% live birth) than the HR followed by the levonorgestrel intrauterine system subgroup (82.5% CR, 25.3% pregnancy, 16.3% live birth).
CONCLUSIONS: Hysteroscopic resection followed by progestins appears to be a promising choice for fertility-sparing treatment in young patients with AH and EEC, with effective and safe responses. The live birth rate remains to be improved by providing medical guidance and encouragement.

VEIN STEP was conducted to collect international data on the management of chronic venous disease (CVD) and to assess the effectiveness of conservative treatments for the relief of CVD signs and symptoms.
This international, observational, prospective, longitudinal, cohort study recruited adult outpatients consulting for symptomatic CVD. The primary objective was the effectiveness of conservative treatments on symptoms, signs and quality of life in a real-life setting assessed using a range of patient-reported outcome measures: 10-cm Visual Analog and Patient Global Impression of Change scales for symptoms; Venous Clinical Severity Score for physician assessment of signs; and 14-item ChronIc Venous Insufficiency Questionnaire (CIVIQ-14) for quality of life. At inclusion, patients were prescribed conservative treatment according to the physicians\' usual practice. Follow-up visits took place at weeks 2 and 4, with an optional week 8 visit.
The analysis set comprised 6084 subjects (78% female) from nine countries with a mean age of 50.6 ± 13.8 years and BMI of 28.0 ± 4.9 kg/m2. The most common CEAP classifications were C1 (23.0%), C2 (31.6%), and C3 (30.7%). Conservative therapy consisted of oral venoactive drugs (VADs; 95.8% of subjects) including micronized purified flavonoid fraction (MPFF 75.5%) and diosmin (18.8%), compression (52.0%), and topicals (31.5%). Conservative therapy led to global symptom improvement in 89% of patients after 2 weeks and 96% at 4 weeks. Pain, leg heaviness, cramps, and sensation of swelling were improved in 82%, 71%, 45.5%, and 46% of patients, respectively. Conservative therapy was associated with a decrease over time in patient-assessed global symptom intensity: - 2.37 ± 1.73 (P < 0.001) and physician-assessed disease severity - 1.83 ± 2.82 (P < 0.001). Among the VADs, MPFF-based conservative therapy was associated with the greatest reduction in symptom and sign intensity. Improvements in CIVIQ-14 were observed with all treatments but were greatest for MPFF.
In this prospective study conducted in the real-world setting, treatment with conservative therapy, in particular MPFF, was associated with meaningful improvements in the clinical signs and symptoms of disease as well as in quality of life in patients with CVD.
ClinicalTrials.gov identifier NCT04574375.
OBJECTIVE: The VEIN STEP study aimed to gather global data on managing chronic venous disease (CVD) and evaluate the usefulness of conservative (non-surgical) treatments for improving CVD signs and symptoms.
METHODS: Persons included in the study group had symptomatic CVD and were visiting outpatient clinics. The main aim was to measure how well treatments improved symptoms, physical signs of the illness, and quality of life. Different methods were used to measure these aspects, such as rating symptoms on a 10-point scale and using questionnaires completed by patients and doctors.
RESULTS: 6084 participants from nine countries joined the study. They were mostly women (78%) with an average age of around 50. Common symptoms included leg pain and leg heaviness. Treatments consisted mainly of drugs active on vein function, like MPFF and diosmin, along with compression stockings and creams. Conservative treatment led to symptom improvement in 89% of patients after 2 weeks and 96% at 4 weeks. Pain and leg heaviness improved in most patients (82% and 71% over the same period) while cramps, and swelling showed improvement in 45.5% and 46% of patients, respectively. Patients reported a significant decrease in symptom intensity, and doctors observed a reduction in disease severity. MPFF was associated with the highest reduction in symptom intensity. Improvements in quality of life were observed with all treatments but were greatest for MPFF.
CONCLUSIONS: The study highlights that conservative treatments, especially MPFF, are associated with significant improvements in the clinical signs and symptoms of patients with CVD as well as in their quality of life.

UNASSIGNED: Spontaneous isolated abdominal aortic dissection (SIAAD) is a rare aortic emergency and not yet fully understood. This study aims to report the characteristics and treatments of 31 patients with SIAAD in the past 12 years.
UNASSIGNED: A total of 31 consecutive patients with SIAAD between 2010 and 2022 were included. The clinical manifestations, treatment strategies, and outcomes were reviewed. Following the SVS/STS reporting standard, we compared the clinical characteristics with different locations of primary entry, or different numbers of dissected zones. Furthermore, we compared the effects of surgical and conservative therapies on the outcome during the follow-up.
UNASSIGNED: Among the 31 patients with SIAAD, 16 (51.6%) were in the acute phase on admission. The primary entry of SIAAD was mainly located in Zone 9 (67.7%). Most patient presented with dissection involving 1 or 2 aortic zones (61.3%). In addition, 35.5% and 64.5% of SIAADs involved the visceral and iliac arteries, respectively. Compared with asymptomatic SIAADs, the symptomatic ones had longer dissection lengths (P = 0.008) and tended to involve iliac artery more frequently (P = 0.098). There were differences in the number of dissected aortic zones (P = 0.005) among patients with primary entry located in Zone 5 (Supraceliac aorta), Zone 6-8 (Paravisceral aorta) and Zone 9 (Infrarenal aorta). The involvement of visceral artery (P = 0.039) and iliac artery (P = 0.006) was significantly different between the subgroups of SIAAD involving one, two, and three or more aortic zones. The cumulative incidence of adverse false lumen progression events was significantly lower (P = 0.000) and the rate of false lumen thrombogenesis or disappearance was higher in patients receiving surgery (P = 0.001). The cumulative all-cause mortality was 9.7% at 1-year, and 19.7% at 5-year, with no significant difference between surgical and conservative therapies.
UNASSIGNED: Clinical features of SIAAD vary depending on the location of the primary entry and the number of dissected aortic zones. Although surgery was not associated with a lower all-cause mortality compared with conservative therapy, it was associated with a lower incidence of adverse false lumen progression and a higher rate of aortic remodeling.

UNASSIGNED: Bronchopleural fistula (BPF) is a relatively rare postoperative complication with high mortality. The management is tough and controversial. The aim of this study was to compare the short and long-term outcomes between the conservative and the interventional therapy in postoperative BPF. We also concluded our own strategy and experience of treatment in postoperative BPF.
UNASSIGNED: Postoperative BPF patients with malignancies, aged from 18 to 80 years old who had undergone thoracic surgery between June 2011 and June 2020, were included in this study and followed up from 20 months to 10 years. They were retrospectively reviewed and analyzed.
UNASSIGNED: Ninety-two BPF patients were included in this study, 39 of whom underwent interventional treatment. Significant differences were found in the 28-day and the 90-day survival rates between the conservative and the interventional therapy (P=0.001, 43.40% vs. 76.92%; P=0.006, 35.85% vs. 66.67%). Simple conservative therapy was independently associated with 90-day mortality between the groups in postoperative BPF [P=0.002, hazards ratio (HR) =2.913, 95% confidence interval (CI): 1.480-5.731].
UNASSIGNED: Postoperative BPF is notorious for its high mortality. Surgical and bronchoscopic interventions are recommendable in postoperative BPF as they guarantee better short and long-term outcomes compared with the conservative therapy.

Cancer-induced bone pain (CIBP) has a considerable impact on patients\' quality of life as well as physical and mental health. At present, patients with CIBP are managed according to the three-step analgesic therapy algorithm proposed by the World Health Organization. Opioids are commonly used as the first-line treatment for moderate-to-severe cancer pain but are limited due to addiction, nausea, vomiting and other gastrointestinal side effects. Moreover, opioids have a limited analgesic effect in some patients. In order to optimize the management of CIBP, we must first identify the underlying mechanisms. In some patients, surgery, or surgery combined with radiotherapy or radiofrequency ablation is the first step in the management of CIBP. Various clinical studies have shown that anti-nerve growth factor (NGF) antibodies, bisphosphonates, or RANKL inhibitors can reduce the incidence and improve the management of cancer pain. Herein, we review the mechanisms of cancer pain and potential therapeutic strategies to provide insights for optimizing the management of CIBP.

A meta-analysis study to assess the influence of instant surgery (IS) compared with conservative therapy (CT) on paediatric complicated acute appendicitis (CAA) post-surgery wounds. A comprehensive literature examination until January 2023 was implemented, and 2098 linked studies were appraised. The picked studies contained 66 674 subjects with paediatric CAA post-surgery wounds in the picked studies\' baseline; 64 643 of them were using IS, and 2031 were using CT. The odds ratio (OR) in addition to 95% confidence intervals (CIs) were used to calculate the consequence of the IS compared with the CT on paediatric CAA post-surgery wounds using the dichotomous and continuous styles and a fixed or random model. The IS had a significantly higher wound infection (OR, 4.97; 95% CI, 2.35-10.54, P < .001) with moderate heterogeneity (I2  = 57%) compared with the CT in a paediatric CAA post-surgery wound. However, no significant difference was found between IS and CT in total antibiotic duration (MD, -5.34; 95% CI,-12.67 to -1.98, P = .15) with high heterogeneity (I2  = 95%) in paediatric CAA post-surgery wounds. The IS had a significantly higher wound infection; however, no significant difference was found in total antibiotic duration compared with the CT in paediatric CAA post-surgery wounds. Although precautions should be taken when commerce with the consequences because most of the studies picked for this meta-analysis had low sample sizes.

Cervical giant cell tumor of the bone (GCTB) is a rare, primary benign bone tumor in pediatric patients. Surgery remains the primary choice for treating resectable cervical GCTB. Additional adjuvant therapeutic options are available for patients with unresectable cervical GCTB, including the anti-RANKL monoclonal antibody, denosumab. We represented a case incidentally found in a 7-year-old female, who complained severe craniocervical pain, grade 2-3 dysphagia, dysphonia, hypesthesia, and extremity weakness. The patient showed an impressive clinical response to denosumab, both clinically and radiologically, without adverse events or recurrence. To date, this is the youngest patient ever reported to have a progressive Enneking stage II C3 GCTB treated with denosumab alone. Denosumab can be administered as a single and conservative therapy for pediatric patients with unresectable upper cervical GCTB, avoiding the risks and morbidity of surgical and radiative treatment.

A meta-analysis was conducted to analyze the incidence of typical and atypical headaches and outcomes following various treatments in patients with Chiari I malformation.
Headache is the most common symptom of Chiari malformation, which can be divided into typical and atypical subgroups to facilitate management. Much controversy surrounds the etiology, prevalence and optimal therapeutic approach for both types of headaches.
We identified relevant studies published before 30 July 2022, with an electronic search of numerous literature databases. The results of this study were reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement.
A total of 1913 Chiari malformation type I CIM patients were identified, 78% of whom presented with headache, within this group cephalgia was typical in 48% and atypical in 29% of patients, and migraine was the most common type of atypical headache. The ratio of typical/atypical headaches with international classification of headache disorders diagnosis was 1.53, and without international classification of headache disorders diagnosis was 1.56, respectively. The pooled improvement rates of typical headaches following conservative treatment, extradural decompression and intradural decompression were 69%, 88%, and 92%, respectively. The corresponding improvement rates for atypical headaches were 70%, 57.47%, and 69%, respectively. The complication rate in extradural decompression group was significantly lower than in intradural decompression group (RR, 0.31; 95% CI: 0.06-1.59, I2 = 50%, P = 0.14). Low reoperation rates were observed for refractory headaches in extradural decompression and intradural decompression groups (1%).
The International Classification of Headache Disorders can assist in screening atypical headaches. extradural decompression is preferred for typical headaches, while conservative therapy is optimal for atypical headaches. A definite correlation exists between atypical headaches and Chiari Malformation Type I patients with higher prevalence than in the general population. Importantly, decompression is effective in relieving headaches in this particular patient population.

Left ventricle (LV) pseudoaneurysm is a rare disorder post-acute myocardial infarction (AMI). Resection or closure of the pseudoaneurysm by surgery is recommended due to the high propensity of pseudoaneurysm rupture while surgery has also high risks. Conservative therapy could be acceptable in small pseudoaneurysms or patients with high surgical risks. Nevertheless, the risk evaluation and grasp of indication are not clear. This case reported an acute cyst-like LV pseudoaneurysm formation post-AMI-induced myocardial free wall rupture (MFWR), and the patient recovered with spontaneous closure of the fissure and shrinkage of the LV pseudoaneurysm through non-surgical therapy. Based on the observations in the echocardiogram, we proposed that intermittent closing of the fissure and interruption of the blood flow between the LV and the pseudoaneurysm due to LV contraction alleviated stress change on the pseudoaneurysm. The narrow fissure, small pseudoaneurysm, and intermittently interrupted blood flow that benefit fissure healing and pseudoaneurysm stabilization could indicate the prognosis of this patient. Drugs like β-blocker that decreased the stress on the pseudoaneurysm also led to the risk reduction of pseudoaneurysm rupture. To our knowledge, this is the first case that reports a spontaneous closure of LV pseudoaneurysm. The size of the fissure and the pseudoaneurysm, as well as the corresponding hemodynamic state, could be valuable to evaluate the risk and prognosis of the pseudoaneurysm. Optimized medical management was also helpful to pseudoaneurysm stabilization.
