Is the whole-day use of surgical masks during the coronavirus pandemic increasing the contamination of surgeons' masks?

Evaluating the impact of surgical masks' conservation practices during the Coronavirus Disease pandemic in the bioburden of the operating room seems imperative, as they play a critical role against this pandemic. We demonstrate that surgeons' masks tend to be contaminated due to the conservation techniques to maximize protection equipment during the pandemic. Health institutions should highlight the importance of surgical mask exchange to avoid increments in surgical mask contamination.

Lipofibromatous Hamartoma in a Hispanic Patient with macrodactyly: a rare peripheral nerve tumor causing recurrent carpal tunnel syndrome.

This is a rare case of a 42-year-old Hispanic male with macrodactyly who presented with recurrent carpal tunnel syndrome (CTS) due to Lipofibromatous Hamartoma (LFH). A slowly growing mass in his right palm with pain and numbness, along with motor and sensory deficits in the median nerve distribution, was reported since the past year prior to visit. Previous open carpal tunnel release was performed at 16 years of age due to CTS without complications. The diagnosis of LFH was made based on ultrasound, electromyography test and physical examination. An extended open carpal tunnel release with transection of transverse ligament was performed. The 24-month postoperative evaluation showed complete resolution of symptoms. This report illustrates the management of a recurrent CTS due to LFH in a Hispanic adult patient with macrodactyly that was successfully treated with a carpal tunnel decompression.

Giant cell tumor of bone at the proximal epiphysis of humerus in a skeletally immature patient: A case report.

INTRODUCTION: Giant cell tumor of bone (GCTB) in skeletally immature (SI) patients are rare benign lesions that have locally aggressive growth pattern and high risk of recurrence. The presence of GCTB at the proximal epiphysis of humerus in SI patients has never been described in literature. PRESENTATION OF CASE: This report shows the case of a 10-year-old SI male who presented with a GCTB at the proximal epiphysis of humerus that was treated with curettage, cement and adjuvant therapy. DISCUSSION: The presence of a lytic growing lesion at the proximal humerus in a SI patient should alert clinicians to consider GCTB in their differential diagnosis. The management of GCTB in SI patients is challenging for orthopaedic surgeons. Tumor resection with cementation and adjuvant therapy has been described as a method rationale to prevent the recurrence and preserve the joint function in SI patients with GCTB at the proximal epiphysis of humerus. Clinicians should continue to monitor these patients with radiographic imaging for possible recurrence, metastasis or growth plate injury. CONCLUSION: Tumor resection with cementation and adjuvant therapy offers a treatment alternative to prevent the recurrence and preserve the joint function in SI patients with GCTB at the proximal epiphysis of humerus. The use of a prothesis in a SI patient should avoided if possible, to prevent implant-related complications and damage to the growth plate.
