Meningioma is a common neoplasm of the central nervous system; however, primary extracranial meningioma of the paranasal sinus, especially the maxillary sinus, is rare. We report a case of primary extracranial meningioma (fibrous type) of the maxillary sinus and present a literature review of the imaging features that correlate with fibrous meningioma.
2.Management of Alveolar Cleft.
Archives of Craniofacial Surgery 2015;16(2):49-52
The alveolar cleft has not received as much attention as labial or palatal clefts, and the management of this cleft remains controversial. The management of alveolar cleft is varied, according to the timing of operation, surgical approach, and the choice of graft material. Gingivoperiosteoplasty does not yet have a clear concensus among surgeons. Primary bone graft is associated with maxillary retrusion, and because of this, secondary bone graft is the most widely adopted. However, a number of surgeons employ presurgical palatal appliance prior to primary alveolar bone graft and have found ways to minimize flap dissection, which is reported to decrease the rate of facial growth attenuation and crossbite. In this article, the authors wish to review the literature regarding various advantages and disadvantages of these approaches.

Development of transfusion-related acute lung injury (TRALI), a non-cardiogenic pulmonary edema, after blood transfusion, is a rare but potentially leading cause of mortality from blood transfusion. We report on a case of TRALI in a 51-year male with acute calculous cholecystitis and liver cirrhosis. As preoperative treatment, he was given ten units of fresh frozen plasma (FFP) for 3 days before the operation. During the transfusion of the 10th unit of FFP, he experienced a sudden onset of hemoptysis, tachypnea, tachycardia, and cyanosis. Bilateral pulmonary infiltration not observed on the chest X-ray at the visit was newly developed. There was no evidence of volume overload but severe hypoxemia. Blood transfusion was stopped and he recovered fully after 8 days of oxygen therapy through a nasal cannula. Although HLA and HNA antibodies were not detected in the donor's blood, HLA antibodies (A2, B57, B58) were detected in the patient's blood. We reported this meaningful case of TRALI that occurred after transfusion of only fresh frozen plasma which did not contain human leukocyte antibody in a patient with HLA antibody.

Chondroid synringoma (CS), pleomorphic adenoma of skin, is a benign tumor found in the head and neck region. CS was first reported in 1859 by Billorth for the salivary gland tumor. The usual presentation is an slowly growing, asymptomatic mass. A 53-year-old female with a history of chondroid synringoma had presented with multiple firm, nodular masses found in the left nostril area. The lesion had been excised 8 years prior and was diagnosed histopathologically, but had gradually recurred. Excision of the mass located in subcutaneous layer revealed four whitish, firm tumors surrounded with capsular tissue. Neither recurrence nor complications occurred during the 18 months follow-up period. In the head and neck region, chondroid syringoma should always be considered in differential diagnosis of soft tissue masses despite its rare incidence. For that reason, excisional biopsy with clear margin is the optimal diagnostic as well as therapeutic choice. We report a case of recurred chondroid syringoma on the nose in female patient.

Congenital defects of the pericardium, which are generally asymptomatic, are rare disorders characterized by complete or partial absence of the pericardium. Here, we report a rare case of a 19-year-old male who was incidentally diagnosed with congenital absence of the left pericardium during examination for symptoms of pneumothorax. Chest radiography and CT revealed a collapsed left lung without any evidence of trauma, no unusual findings of free air spaces along the right side of the ascending aorta, heart shifted toward the left side of the thorax, and a shallow chest. Subsequent thoracoscopy confirmed the absence of the left pericardium and displacement of the heart toward the left thoracic cavity. We further discuss the correlation between radiologic images and surgical findings of a congenital pericardial defect associated with spontaneous pneumothorax.

When stenting is applied to treat myocardial infarction, antiplatelet agents are administered to prevent thrombosis, which increases the risk of bleeding. Patients with myocardial infarction are also more likely to have osteoarthritis simultaneously, because both diseases occur frequently in elderly patients. Patients with osteoarthritis often use analgesics, especially nonsteroidal anti-inflammatory drugs (NSAIDs); hence, patients with both diseases use analgesics and antiplatelet agents simultaneously. The risk of bleeding increases with the use of antiplatelet agents and this is further increased when NSAIDs are added. We would like to report a case that reflects this situation. A 60-year-old man underwent stenting after ST-elevation myocardial infarction, and was treated with aspirin and clopidogrel. This patient also received a pelubiprofen prescription from another physician to treat osteoarthritis. After the patient took pelubiprofen twice, he found a bruise on his wrist and reported it to the pharmacist. It is unlikely that this is rare in community pharmacies, so pharmacists should pay careful attention to the concomitant administration of analgesics to patients receiving antiplatelet agents and should provide appropriate education to patients.

Clinics in Orthopedic Surgery 2025;17(2):308-316
Background:
This study compares ultrasound and surgical findings of anatomical variations in de Quervain’s disease.
Methods:
Seventy-four wrists from patients with unilateral de Quervain’s disease were examined through ultrasonography and surgery. Presence of intracompartment septum, abductor pollicis longus (APL) slips, and selective stenosis were verified by both methods. Two orthopedic surgeons assessed ultrasound findings for intra- and interobserver reliability.
Results:
Amongst 74 participants (43 women and 31 men), 60.8% had a complete septum, 31.1% had an incomplete septum, and 8.1% had no septum; 70.3% had multi-slip APL and 66.2% had extensor pollicis brevis stenosis. Surgical and ultrasonographic findings displayed a high level of sensitivity and specificity. Intraobserver reliability was high, and interobserver reliability was substantial.
Conclusions
The study confirms ultrasonography’s reliability in identifying anatomical variations in de Quervain’s disease, with high sensitivity, specificity, and substantial intra- and interobserver reliability, emphasizing its usefulness in preoperative assessment and planning.
