Meningioma is one of the most common types of benign primary brain tumors in older adults, and multiple meningiomas are reported in fewer than 1% to 10% of cases. However, there is no definitive treatment guideline for patients with multiple meningiomas. An 80-year-old man presented with abruptly impaired cognition and was found to have two distinct meningiomas located in the temporal and frontal lobes. A single frontotemporal craniotomy was performed to remove both tumors. Pathological analysis revealed different subtypes and World Health Organization grades for each mass. The patient showed symptomatic improvement, experienced no postoperative complications, and exhibited no signs of recurrence during a 1-year follow-up period with evaluations at 3-month intervals. Despite the absence of a standard treatment for multiple meningiomas, surgical resection in a single procedure is feasible in selected patients.

Objective: Decompression with instrumented fusion is a common approach for treating spinal metastatic disease. However, in many cases, poor bone quality and compromised general condition increase the likelihood of mechanical failure and other complications. This study investigated complications, including those related to surgery, following decompression and fusion in patients with spinal metastatic disease. Methods: A study at a single tertiary medical center focusing on surgical details and perioperative complications was performed on 35 patients who underwent spinal surgery due to metastatic spinal disease based on a review of a prospective database. Data on patients' underlying conditions and the status of the primary tumors were collected, and various complications that occurred within the first month after surgery were analyzed. Results: During the study, 35 patients (mean age, 66.5 years; 26 men) were enrolled. The most frequent primary cancers were lung (34%) and prostate cancer (17%), followed by liver and breast cancer and others. The overall complication rate was 37% (14% surgery-related complications, 23% general complications). In all cases, surgery was performed due to lower extremity weakness, and 59% of patients showed improvements in motor function after surgery. Furthermore, 23% of patients regained the ability to walk. Conclusion Surgery for spinal metastasis is frequently performed as an emergency due to the severity of symptoms such as lower extremity weakness. Despite a high risk of acute complications, the procedure has significant benefits, including improvement in weakness and recovery of walking ability. Therefore, proactive treatment using appropriate surgical techniques is recommended.

Purpose: Diffuse large B-cell lymphoma (DLBCL) is the most common hematologic malignancy worldwide. Although substantial improvement has been achieved by the frontline rituximab-based chemoimmunotherapy, up to 40%-50% of patients will eventually have relapsed or refractory disease, whose prognosis is extremely dismal. Materials and Methods: We have carried out two prospective cohort studies that include over 1,500 DLBCL patients treated with rituximab plus CHOP (#NCT01202448 and #NCT02474550). In the current report, we describe the outcomes of refractory DLBCL patients. Patients were defined to have refractory DLBCL if they met one of the followings, not achieving at least partial response after 4 or more cycles of R-CHOP; not achieving at least partial response after 2 or more cycles of salvage therapy; progressive disease within 12 months after autologous stem cell transplantation. Results: Among 1,581 patients, a total of 260 patients met the criteria for the refractory disease after a median time to progression of 9.1 months. The objective response rate of salvage treatment was 26.4%, and the complete response rate was 9.6%. The median overall survival (OS) was 7.5 months (95% confidence interval, 6.4 to 8.6), and the 2-year survival rate was 22.1%±2.8%. The median OS for each refractory category was not significantly different (p=0.529). Conclusion In line with the previous studies, the outcomes of refractory DLBCL patients were extremely poor, which necessitates novel approaches for this population.

Few cases of injuries caused by wild boars have been reported in the literature. Here, we present the case of a 64-year-old male patient who was attacked by a wild boar. The patient had a laceration to the right forehead and a penetrating wound in the area before the right auricle. Computed tomography scan revealed traumatic subarachnoid hemorrhage, subdural hemorrhage, right temporal lobe contusion hemorrhage, pneumocephalus, right zygomatic arch and temporal bone fracture, and right coronal process fracture of the mandible.Prophylactically, 2,000 mg of ceftriaxone and 400 mg of moxifloxacin were intravenously administered every 24 hours. An emergency craniectomy was performed because the skull fracture was an open fracture and control of the increased intracranial pressure was necessary. Inactivated Rabies Virus Vaccine was also administered postoperatively. We concluded that, unlike typical wounds from other traumatic causes, the risk of wound infection is higher. In order to reduce morbidity and mortality due to wild boar attacks, rapid stabilization of the patient’s vital signs, prevention of infection with appropriate antibiotics, and surgical intervention at the appropriate time and method are necessary.

Purpose: We introduce a “cold steel” hammer-chisel technique for endoscopic dacryocystorhinostomy, then compare postoperative outcomes between this technique and a drill technique. Methods: This study included 191 patients (297 eyes) with nasolacrimal duct stenoses or obstructions who underwent endoscopic dacryocystorhinostomy using the hammer-chisel or drill technique. Surgical outcomes were compared via follow-up screening for epiphora and anatomical complications such as granuloma and fibrous membrane formation, canalicular obstruction, and synechiae. Results: Postoperative anatomical complications occurred in 29 eyes (18.6%) in the hammer-chisel group and 51 eyes (36.2%) in the drill group (p = 0.001). The anatomical failure rate was higher in the drill group [28 eyes (19.9%)] than in the hammer-chisel group [18 eyes (11.5%); p = 0.038]. Functional failure was observed in 13 eyes (8.3%) in the hammer-chisel group and 13 eyes (9.2%) in the drill group (p = 0.787). The mean operation time was significantly longer in the drill group (35.5 ± 10.4 minutes vs. 25.4 ± 9.1 minutes) (p < 0.001). Conclusions During endoscopic dacryocystorhinostomy, osteotomy with a hammer-chisel is more successful and leads to fewer complications than osteotomy with a drill.

Purpose: Febrile neutropenia (FN) can cause suboptimal treatment and treatment-related mortality (TRM) in diffuse large B-cell lymphoma (DLBCL) patients treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP). Materials and methods: We conducted a prospective cohort study to evaluate the effectiveness of pegfilgrastim prophylaxis in DLBCL patients receiving R-CHOP, and we compared them with the PROCESS cohort (n=485). Results: Since January 2015, 986 patients with DLBCL were enrolled. Pegfilgrastim was administered at least once in 930 patients (94.3%), covering 90.3% of all cycles. FN developed in 137 patients (13.9%) in this cohort (23.7% in the PROCESS cohort, p<0.001), and 4.2% of all cycles (10.2% in the PROCESS cohort, p<0.001). Dose delay was less common (≥3 days: 18.1% vs. 23.7%, p=0.015; ≥5 days: 12.0% vs. 18.3%, p=0.023) in this cohort than in the PROCESS cohort. The incidence of TRM (3.2% vs. 5.6%, p=0.047) and infection-related death (1.8% vs. 4.5%, p=0.004) was lower in this cohort than in the PROCESS cohort. The 4-year overall survival (OS) and progression-free survival (PFS) rates of the two cohorts were not different (OS: 73.0% vs. 71.9%, p=0.545; PFS: 69.5% vs. 68.8%, p=0.616). However, in patients aged ≥75 years, the 4-year OS and PFS rates were higher in this cohort than in the PROCESS cohort (OS: 49.6% vs. 33.7%, p=0.032; PFS: 44.2% vs. 30.3% p=0.047). Conclusion Pegfilgrastim prophylaxis is effective in the prevention of FN and infection-related death in DLBCL patients receiving R-CHOP, and it also improves OS in patients aged ≥75 years.

Objective: We investigated the clinical and radiological outcomes of a cement augmented anterior reconstruction and decompression without pedicle screw fixation in patients with osteoporotic thoracolumbar vertebral fracture with myelopathy. Methods: There were 2 male and 6 female patients with thoracolumbar fracture and myelopathy included in the study. The mean follow-up period was more than 1 years.The anterolateral decompression and cement augmented anterior reconstruction with poly(methyl methacrylate) (PMMA) was performed. Demographic data, clinical outcomes, perioperative parameters and radiologic parameter were retrospectively evaluated. Results: The symptoms due to myelopathy were improved in all patients. The preoperative median visual analog scale score for lower back and leg were 8.5 that improved 4.25 and 3 at last follow up. The preoperative function state showed a median Oswestry Disability Index score 61.5 that improved 33. After surgery, preoperative encroachment of the spinal canal (5.12 mm, 37%) was disappeared. The median height of fractured vertebral body significantly increased from 7.83 to 12.63 mm. At the last follow-up point, the median height was 9.91 mm. The median kyphotic deformity was improved from 22.12° to 14.31°. At the final followup, the improvement was preserved (median value: 15.03). The acute complication according to PMMA such as leakage and embolization was none, but adjacent compression fracture as late complication according to cement augmentation was. One patient developed surgical site infection. Conclusion On the basis of the preliminary results, we considered that anterolateral decompression and PMMA augmentation might be an optimal method for treating osteoporotic fracture with myelopathy in elderly patients or those with multiple medical comorbidities.

Background: Palmoplantar pustulosis is a specific form of localized pustular psoriasis occurring on the palm and sole. Multiple therapeutic options, including topical and systemic agents as well as phototherapies, are available for palmoplantar pustulosis; however, treatment outcomes are not satisfactory in most cases. Recently, a gain-switched 311-nm Ti:Sapphire Laser was developed and showed good treatment response in vitiligo and atopic dermatitis. Objective: To investigate the efficacy and safety of the 311-nm Ti:Sapphire Laser in the treatment of palmoplantar pustulosis. Methods: A total of 24 patients with palmoplantar pustulosis were treated with a 311-nm Ti:Sapphire Laser twice a week for up to 32 sessions and had a 3-month follow-up visit. The treatment dose started at 300 mJ/cm 2 and was increased by 50 mJ/cm 2 at each subsequent session. The Palmoplantar Pustular Psoriasis Area and Severity Index score, 5-grade patient satisfaction score, and adverse events were evaluated. Results: The mean Palmoplantar Pustular Psoriasis Area and Severity Index score decreased from 8.31±3.31 at baseline to 4.75±2.70 at 16 sessions, 3.26±2.18 at 32 sessions, and 4.05±2.19 at follow-up visit. In the subgroup analysis, non-smokers and emollients user groups showed better responses in Palmoplantar Pustular Psoriasis Area and Severity Index (p=0.033 and p=0.027, respectively). Adverse effects, including burning sensation and transient erythema, were limited and well-tolerated. Conclusion The 311-nm Ti:Sapphire Laser can be considered as a treatment option for palmoplantar pustulosis.Moreover, habitual risk factor modifications, such as smoking cessation and steady use of emollients, can impact treatment outcomes in patients with palmoplantar pustulosis.
