Efficacy and Safety of Anti-VEGF Injections and Surgery for AMD-Related Submacular Hemorrhage: A Systematic Review & Meta-Analysis.

TOPIC: This systematic review and meta-analysis investigates the efficacy and safety of anti-vascular endothelial growth factor (anti-VEGF) injections compared to surgical intervention in improving visual acuity (VA) and reducing complications for patients with submacular hemorrhage (SMH) due to neovascular age-related macular degeneration (AMD). CLINICAL RELEVANCE: Determining the optimal intervention for SMH in AMD is crucial for patient care. METHODS: We included studies on anti-VEGF injections or surgical interventions for SMH in AMD from 7 databases, searched up to May 2024. Data extraction and quality assessment were done by two independent reviewers. Certainty of evidence was assessed GRADE approach. Meta-analysis employed random-effects models. Primary outcomes were pooled mean logMAR VA difference (initial examination minus last follow-up VA) and adverse events rates. RESULTS: A total of 43 observational studies were included: 21 (960 eyes) on anti-VEGF and 22 (455 eyes) on surgery. Comparisons were made across separate studies due to lack of head-to-head studies. Meta-analysis included 11 anti-VEGF studies (444 eyes) and 12 surgical studies (195 eyes) for VA outcomes. The mean difference (MD) in VA was -0.16 (95%CI: -0.26,-0.07) for anti-VEGF and -0.36 (95%CI: -0.68,-0.04) for surgery, with no significant difference between groups (X2=1.70, df =1, p=0.19). Heterogeneity was high in surgical studies (I2=96.2%, tau2=0.23, p<0.01) and negligible in anti-VEGF studies (I2=7%, tau2=0.003, p=0.38). GRADE certainty was moderate for anti-VEGF and low for surgery. Anti-VEGF had lower rates of cataract (0% vs 4.6%), proliferative vitreoretinopathy (PVR, 0.1% vs 2.0%), and retinal detachment (RD, 0.1% vs 10.6%), but similar rates of recurrent hemorrhage (5.4% vs 5.3%). Complications were summarized descriptively due to zero cell problem. CONCLUSION: Both anti-VEGF and surgery treat SMH in AMD with similar VA outcomes but different safety profiles. Anti-VEGF is preferred for less severe hemorrhage, while surgery is suited for extensive hemorrhage. Despite uncertain comparative VA outcomes, treatment should be guided by clinical judgment and patient factors.

Filler found in bone: Surgical removal of polyacrylamide hydrogel (Amazingel) from the mandible after 24 years: A case report and literature review.

Polyacrylamide hydrogel (PAAG) is widely regarded as a safe soft tissue filler and has been extensively utilized for cosmetic enhancements, such as breast and facial augmentation in China from 1997 until its ban in 2006. Common complications associated with its use include inflammation, infection, granulomas, fibrosis, gel migration, and facial and soft tissue deformities. This case report describes a 45-year-old Chinese woman who experienced PAAG migration into her mandible 24 years after facial augmentation, causing irritation of the mandibular alveolar nerve - apparently the first documented instance of this occurrence. Surgical intervention was necessary to remove the migrated gel and associated calcifications. A literature review explored adverse events and management strategies for PAAG complications in cosmetic procedures. While generally considered safe, this report underscores the importance of meticulous injection techniques and careful anatomical site selection to prevent such severe complications.

Complex Factors in Hydrocephalus Development in Tuberous Sclerosis Complex: A Case Report of Subependymal Giant Cell Astrocytoma.

Subependymal giant cell astrocytoma (SEGA) associated with tuberous sclerosis complex (TSC) occurs in 5-20% of TSC patients, with a subset developing hydrocephalus. We present a case of a 14-year-old male diagnosed with TSC in the neonatal period who developed SEGA and subsequent hydrocephalus. Despite reducing the tumor size with the mammalian target of rapamycin (mTOR) inhibitors, ventricular enlargement persisted, indicating that obstructive hydrocephalus due to the foramen of Monro blockage was not the sole mechanism. Elevated cerebrospinal fluid (CSF) protein levels suggested additional factors like impaired CSF outflow. This case underscores the need for comprehensive treatment strategies and further research to better understand and manage hydrocephalus in TSC patients with SEGA.

Surgical removal of an impaled unexploded mortar shell into the chest: Case review from a war-zone.

INTRODUCTION AND SIGNIFICANCE: The surgical removal of unexploded mortar shells is rarely documented in the literature. Since most cases occur within war or conflict regions, reporting such instances is vital for optimizing and enhancing surgical practices, particularly in low-resource settings. CASE PRESENTATION: We report the case of a 35-year-old man who sustained an injury from a 60 mm unexploded mortar shell, penetrating the patient's right posterior chest in the right paravertebral region of the 4th thoracic vertebra, causing intrathoracic injuries, multiple rib fractures, and a right pneumothorax. The patient was immediately resuscitated and transferred to the operating room. The projectile was removed without direct contact with metal instruments. A right chest tube was then inserted and the injured area was repaired, resulting in an uneventful postoperative recovery. CLINICAL DISCUSSION: Unexploded mortar shell injuries are infrequently documented in the literature. These injuries are seen within war and conflict regions, that have limited accessibility or availability of experienced explosive ordnance disposal (EOD) teams, transporting personnel, and equipped and separated operating theaters. CONCLUSION: Unexploded ordnance and munitions represent an underrecognized and underreported health risk to patients, healthcare providers, and healthcare facilities. These injuries are commonly encountered within regions that lack experienced transport and EOD staff. The need for the establishment of such experienced teams along with providing adequate training for healthcare providers is necessary.

A Pediatric Epidural Catheter Fracture Suspected to Be Caused by a Glue.

A 65-day-old baby boy underwent the Kasai procedure under general and epidural anesthesia. The epidural catheter was inserted between the T11 and T12 vertebrae under general anesthesia, and secured with sterile tape, ethyl-2-cyanoacrylate glue, and film. Intra- and postoperative epidural analgesia was effective and there was no leakage around the insertion site. On the third day post-surgery, we tried to remove the catheter but discovered it was fractured 67mm from the tip. During the ultrasound examination, we observed a hyper-echoic structure located between the laminae of T11/T12. The pediatric orthopedic surgeon recommended removing the catheter to avoid long-term neurological sequelae of leaving the catheter, such as infection, fibrosis, migration, and irritation of neural tissues. It was surgically removed uneventfully on postoperative day 4. We requested the manufacturer to inspect the cross-section of the catheter under a microscope. The cross-section showed that 20% of the area had undergone tearing due to traction, while the remaining 80% was cracked. We also requested the manufacturer simulation after that. The same catheter, fixed on the polyolefin resin plate instead of skin with the same tape and glue, was easily fractured after three days. It is suspected that using ethyl-2-cyanoacrylate glue caused the catheter to fracture. When using glue containing ethyl-2-cyanoacrylate for pediatric epidural catheter fixation, special care is advised.

Removal of fractured peripherally inserted central venous catheter in the leg of a neonate.

An infant with a corrected gestational age of 38 weeks, weighing 3.1 kg, was referred to our pediatric surgical department because of a fractured peripherally inserted central venous catheter in the left lower limb with the end retracting into the deep venous system. An operation was undertaken to remove the PICC. Because the central venous catheter was, unintentionally, placed in the left small saphenous vein and thus positioned in the left femoral vein, the left great saphenous vein was incised to gain access. Subsequently, the catheter could be removed successfully. Fracturing of a peripherally inserted central venous catheter is a rare occurance. Removal depends on vessel size, location and experertise.

Ruptured giant thoracic hydatid cyst presenting with respiratory symptoms.

Pulmonary hydatid disease remains a global public health issue. Symptoms often result from cyst rupture, causing fever, cough, and hemoptysis. Radiographs may show homogeneous masses, air-fluid levels, or the pathognomonic "water lily" sign. Surgical removal is the primary treatment, with early diagnosis crucial to prevent acute hypersensitivity reactions and death.

Primary hepatic malignant triton tumor mimicking hepatocellular carcinoma by demonstrating arterial-phase hypervascularity and subsequent washout on dynamic contrast-enhanced imaging: a case report and literature review.

Background: Malignant Triton tumor (MTT) is a relatively rare subtype of malignant peripheral nerve sheath tumor (MPNST) characterized by rhabdomyosarcoma differentiation. There are no distinct features of MTT, and it is easy to misdiagnose preoperatively. Case presentation: Here, we describe a rare case of primary hepatic MTT in a 56-year-old male who presented with nonspecific abdominal pain for 1 day. Magnetic resonance imaging and abdominal computed tomography revealed an extremely large mass located in the right liver with intratumoral hemorrhage, arterial-phase hypervascularity and subsequent washout on dynamic contrast-enhanced imaging and the possibility of intrahepatic metastasis. Tumor marker levels revealed only an elevated level of alpha-fetoprotein (AFP: 5304.0 ng/mL). Then, he received transcatheter arterial chemoembolization combined with lenvatinib and pembrolizumab, and he was diagnosed with hepatocellular carcinoma. After 3 months of neoadjuvant therapy, we resected the hepatic cancer and adherent diaphragmatic pleura. MTT was confirmed by postoperative pathology and immunohistochemistry. Conclusion: Despite the preoperative diagnosis of hepatocellular carcinoma with a rising serum AFP level, typical CT and MRI findings, histopathology assessment showing MPNST with rhabdomyosarcoma differentiation confirms the diagnosis of primary hepatic MTT.

[Pediatric neurosurgical treatment of aneurysmal bone cyst at the level of thoracic spine]. / Aneurysmás csontcysta gyermek-idegsebészeti megoldása a háti gerinc magasságában.

Aneurysmal bone cysts are benign but locally aggressive bone tumours, most often affecting children and young adults. In this case report, we present the clinical  picture of a 15-year-old boy with progressive, chronic back pain. An MRI of thoracic spine  confirmed a T2 cystic spinal tumour. After considering potential options surgical removal was our choice and gross total removal was achieved with T1-3 short-segment fixation. Aneurysmal bone cysts are often rapidly expanding lesions with vascular  transformation. In order to avoid irreversible damage, in addition to early diagnosis, it is necessary to carefully consider the therapeutic options, perform surgical removal and stabilization as necessary. In case of the presented patient, extensive surgical removal and short-segmentation were performed. At 18 months of follow-up, he had no complaints and was asymptomatic. Follow-up imaging studies showed no residual or recurrent tumour to date.

Association of indications for mandibular third molar coronectomy and the Pell and Gregory and the Winter classification systems.

PURPOSE: The purpose of this study was to determine how the surgeon's decision to perform a mandibular third molar coronectomy or surgical removal is associated with the impaction pattern as classified using Pell and Gregory or Winter's system. METHODS: This observational, cross-sectional study was conducted on 813 mandibular third molars belonging to 565 patients. All patients were referred for removal of the mandibular third molar and had radiographic signs indicating a close relationship with the inferior alveolar nerve. Panoramic images were classified according to the impaction pattern. RESULTS: A coronectomy was performed on 492 (60.5%) mandibular third molars. Most impacted mandibular third molars were class IIB with a mesioangular inclination. A significant association was found between the Pell and Gregory classification and the surgeon's choice (p = 0.002). Winter's classification was not significantly associated with surgeon choice (p = 0.425). CONCLUSION: Mandibular third molar coronectomy is chosen more frequently than surgical removal if molars are class III and position B. TRIAL REGISTRATION NUMBER: Not applicable.

Heterotopic hip ossification resection: monocentric experiences of associated factors, outcomes, and complications.

PURPOSE: The exponential increase in total hip arthroplasty (THA) has led to acute and chronic surgery-related complications. Common chronic and local complications are represented by hip ossification (HO). The aim of our study was to assess the clinical and radiological correlates of patients undergoing surgical removal of heterotopic ossifications after THA and the possible association between HO and prosthetic joint infection. METHODS: Data of 26 patients who underwent surgical removal of periprosthetic calcifications after THA from 2000 to 2022 were analyzed and compared with characteristics of 156 subjects without HO. RESULTS: The preoperative radiographs of patients showed a high-grade Brooker, 3 or 4, later reduced to 1 or 2 in the postoperative radiographs. Ten (38.5%) patients underwent radiotherapy prophylaxis, administered as a single dose 24 h before surgery. In 19 (73%) patients, pharmacological prophylaxis with indomethacin was added in the 30 postoperative days. Only one patient who underwent radiotherapy had a recurrence, while new ossifications were found in three patients without prophylaxis (11.5%). Intraoperative cultures were performed for suspected periprosthetic infection in 8 study group patients. In logistic regression, the presence of HO was significantly and inversely associated with the ASA score (OR = 0.27, 95% CI = 0.09-0.82; P = 0.021) after adjusting. CONCLUSION: Surgical HO removal in symptomatic patients with high-grade disease produces good clinical and radiographic results. Radiotherapy was a good perioperative and preventive strategy for recurrence, also associated with NSAIDs and COX-2 inhibitors.

Surgical management of dentigerous cyst arises from ectopic tooth: A report of three consecutive cases and literature review.

BACKGROUND: Dentigerous cysts are slow-growing, asymptomatic lesions that typically form around the crowns of impacted teeth. They are not detected until they start to harm the tissues around the teeth. AIM: The present study aimed to describe surgical techniques for treating dentigerous cysts associated with ectopic teeth. CASES: Three patients with dentigerous cysts associated with ectopic teeth, their surgical approaches, and the supporting literature are presented herein. In two cases, the surgical technique used was intra-oral, and in one case was extra-oral. Under general anesthesia, dentigerous cyst enucleation and ectopic tooth removal were carried out. DISCUSSION: In the present study, the ectopic tooth cases were all linked to dentigerous cysts. Enucleation or marsupialization treatments could be used to treat dentigerous cysts. Enucleation with the removal of the impacted tooth is the preferred treatment for dentigerous cysts. CONCLUSION: To perform minimally invasive surgery, the position of the ectopic teeth, the accessibility of the surgical site, the degree of bone reduction, and the simplicity of instrumentation should all be considered.

Left Ventricular Myxoma: A Case Report.

Cardiac myxomas are the most common primary cardiac neoplasms, with only a small percentage being found in the left ventricle. Herein, we describe a 25-year-old male who presented with a complaint of chest pain for almost three months and was found to have a 2x2 cm encapsulated tumor attached by a 2-3 mm stalk to the mid-septum, 5 cm below the aortic annulus, via echocardiography. Additionally, a chest CT angiography was performed and revealed a small defect in the left ventricle with a low attenuation density originating from the septum. The tumor was later managed surgically with a median sternotomy approach, and left ventricular myxoma was confirmed histopathologically. Even though cardiac myxomas are incredibly uncommon, they are usually located in the left and right atria and are very unlikely to present in the left ventricle. This incident highlights the importance of taking cardiac myxoma into account as a potential differential diagnosis in cases of chest pain to prevent any further complications.

Presence of intra-aneurysmal thrombi with delayed coil migration after embolization of an aneurysmal subarachnoid hemorrhage: illustrative case.

BACKGROUND: Coil migration is a rare, but notable complication of endovascular treatment. Risk factors include communicating segment aneurysms, aneurysmal shape, and technical factors. Although cerebral blood flow obstruction caused by early coil migration requires urgent coil removal, delayed coil migration is often asymptomatic, making it difficult to determine a treatment strategy. OBSERVATIONS: A 47-year-old woman was referred to the institute with acute-onset headache. She was diagnosed with subarachnoid hemorrhage due to rupture of the right internal carotid artery-posterior communicating artery aneurysm and underwent endovascular coil embolization. Following the procedure, the patient showed no obvious complications; however, 14 days later, images showed coil migration to the distal side, leading to surgical removal. Right frontotemporal craniotomy was performed, and the remaining coil was removed. The aneurysm was clipped again, and blood flow was confirmed. The patient was discharged 12 days after the craniotomy with transient oculomotor nerve palsy. At the 15-month follow-up, there was no aneurysm recurrence and the oculomotor nerve palsy showed improvement. LESSONS: Retrieval of the migrated coil by craniotomy is an effective remedial measure; however, intraoperative complications are common. Early detection, established protocols, and prompt treatment decisions are important for preventing undesirable outcomes.

Surgical Management of an Intentionally Ingested Vape Device Chronically Impacted within the Duodenum of an Adult Male.

Most foreign body ingestion cases are accidental in the adult population. Intentional ingestion of foreign bodies in adults is typically associated with psychiatric disorders or developmental delay. In most cases, foreign bodies pass spontaneously through the gastrointestinal tract or can be managed endoscopically. Rarely, surgical intervention is indicated. We present a unique case of surgical management of an intentionally ingested vape device that was chronically impacted within the duodenum of an adult male present for six weeks before intervention without associated perforation. The foreign object was removed via exploratory laparotomy with duodenotomy and primary duodenorrhaphy with an uncomplicated postoperative course. There are only two previously reported cases of an ingested vape device. One was managed by observation, and the other was removed endoscopically. There are no previously reported cases of an ingested vape device that required surgical management.

Efficacy of intraosseous saline injection for pain management during surgical removal of impacted mandibular third molars: a randomized double-blinded clinical trial.

Background: Surgical extraction of impacted mandibular third molars is the most common procedure performed by oral surgeons. The procedure cannot be performed effectively without achieving profound anesthesia. During this procedure, patients may feel pain during surgical bone removal (at the cancellous level) or during splitting and luxation of the tooth, despite administration of routine nerve blocks. Administration of intraosseous (IO) lignocaine injections during third molar surgeries to provide effective anesthesia for pain alleviation has been documented. However, whether the anesthetic effect of lignocaine is the only reason for pain alleviation when administered intraosseously remains unclear. This conundrum motivated us to assess the efficacy of IO normal saline versus lignocaine injections during surgical removal of impacted mandibular third molars. The aim of this study was to assess the efficacy of IO normal saline as a viable alternative or adjunct to lignocaine for alleviation of intraoperative pain during surgical removal of impacted mandibular third molars. Methods: This randomized, double-blind, interventional study included 160 patients who underwent surgical extraction of impacted mandibular third molars and experienced pain during surgical removal of the buccal bone or sectioning and luxation of the tooth. The participants were divided into two groups: the study group, which included patients who would receive IO saline injections, and the control group, which included patients who would receive IO lignocaine injections. Patients were asked to complete a visual analog pain scale (VAPS) at baseline and after receiving the IO injections. Results: Of the 160 patients included in this study, 80 received IO lignocaine (control group), whereas 80 received IO saline (study group) following randomization. The baseline VAPS score of the patients and controls was 5.71 ± 1.33 and 5.68 ± 1.21, respectively. The difference between the baseline VAPS scores of the two groups was not statistically significant (P > 0.05). The difference between the numbers of patients who experienced pain relief following administration of IO lignocaine (n=74) versus saline (n=69) was not statistically significant (P > 0.05). The difference between VAPS scores measured after IO injection in both groups was not statistically significant (P >0.05) (1.05 ± 1.20 for the control group vs. 1.72 ± 1.56 for the study group). Conclusion: The study demonstrates that IO injection of normal saline is as effective as lignocaine in alleviating pain during surgical removal of impacted mandibular third molars and can be used as an effective adjunct to conventional lignocaine injection.

[Surgery for malignant melanoma - Expected standards]. / A melanoma malignum sebészeti ellátása ­ Elvárható standardok.

Melanoma surgery has changed significantly in recent years. The highly radical operations with many complications, in addition to which the complete and disease-free survival remained low, were gradually replaced by less radical operations. With the introduction of new systemic treatments (targeted and immuno-oncological) in adjuvant indications, certain surgeries, such as elective block dissections, have now been displaced from surgical treatments and the role of surgery has also been re-evaluated. The surgery for primary tumor removal, reexcision, sentinel lymph node biopsy and lymph region surgery, and surgical treatment of skin and distant metastases have changed. In this summary communication, the authors provide an overview of the currently accepted surgical therapy of melanoma malignum based on the international literature and their own practice.

Efficacy of Intranasal Atomized Dexmedetomidine for Sedation in Surgical Removal of Impacted Mandibular Third Molars: A Prospective Study.

AIMS AND OBJECTIVES: To assess the efficacy of dexmedetomidine atomized intranasally for sedation during surgical removal of impacted mandibular third molars. MATERIALS AND METHODS: A prospective randomized trial was conducted on 25 anxious patients between the ages of 18 and 40 who had impacted the lower third molars. An intranasal atomization device was used to give the medication 30 minutes prior to the surgical procedure. The Ramsay sedation score and Observer's assessment of alertness/sedation score were used to assess intranasal sedation. RESULTS: The results of our study state that the sedative effect began to take effect between 30 and 45 minutes later and was nearly back to baseline by 105 minutes after the administration of intranasal dexmedetomidine. CONCLUSION: Intranasal delivery of 1.5mg/kg atomized dexmedetomidine for patients undergoing surgical removal of impacted mandibular third teeth is safe, feasible, and clinically efficient in daycare settings based on the sedation scores, and secondary variables which were assessed.

Successful uniportal thoracoscopic removal of a new generation implantable loop recorder accidentally migrated into the left pleural cavity and concomitant re-implantation: A case report.

INTRODUCTION: With the spread of the use of implantable loop recorders (ILRs) by cardiologists for outpatient cardiac monitoring, intrathoracic migration represents a rare but possible complication occurring after the placement of these devices. Very few cases of ILRs intrathoracic migration into the pleural cavity have been reported, followed in even fewer cases by surgical removal of the devices, but in none re-implantation was performed. PRESENTATION OF CASE: We report the first case of a patient with a new generation ILR accidentally migrated into the postero-inferior costophrenic recess of the left pleural cavity, successfully removed by uniportal video-assisted thoracic surgery (VATS) and submitted to re-implantation of a new ILR in the same operating session. DISCUSSION: To reduce the risk of ILRs intrathoracic displacement, the insertion technique must be performed in the most suitable part of the chest wall, with the correct incision and angle of penetration, by an expert operator. When migrated into the pleural cavity, surgical removal should be performed to avoid the onset of early and late complications. A mini-invasive surgical approach by uniportal VATS could be considered as the first choice, ensuring a favourable patient outcome. Re-implantation of a new ILR can be safely performed in the same operating session. CONCLUSION: In case of intrathoracic migration of ILRs, early removal by mini-invasive approach is recommended as well as concomitant re-implantation. Beyond periodic monitoring of ILRs by cardiologists, strict radiological follow-up with chest X-ray is advisable after implantation, in order to early identify any abnormalities and correctly manage them.

Evaluation of radiographic characteristics and surgical removal of 147 mesiodens.

The aim of this study was to evaluate the radiographic characteristics and surgical removal of mesiodens among patients who had attended the Department of Dentistry, Oral and Maxillofacial-Plastic and Reconstructive Surgery of the Faculty of Medicine, Yamagata University. This study included 121 patients in the final analysis. We retrospectively reviewed medical records including patient age, sex, mesiodens number, direction, position, opportunity for detection, surgical approach and operating time. The 121 patients comprised 82 males and 39 females. Mean age was 7.6 ± 3.1 years (range, 4-35 years). The total number of mesiodens among these 121 patients was 147. Ninety-six patients had one mesiodens, 24 patients had two mesiodens and 1 patient had 3 mesiodens. Seventy-nine mesiodens were detected while taking X-rays for routine dental examination and/or orthodontic treatment at their family dental/orthodontic clinic. Mean operating time for removal of the 147 mesiodens was 32.2 ± 18.1 min. Among the 96 patients with one mesiodens, mean operating time for removal of the mesiodens was 30.7 ± 16.5 min. Operating time for removal of a mesiodens tended to be prolonged with increased distance from the alveolar crest. Early detection of mesiodens on routine radiographic check-ups and surgical planning considering patient age, crown direction, position of the mesiodens will contribute to improved treatment of mesiodens.
