Objective: To study the relation of the sex, age, location and chemotherapy with recurrence of the tumor.
Methods: From January 2000 to August 2010, 47 patients with giant cell tumor of tendon sheath in upper extremity were retrospectively analyzed. Statistical analysis of sex, age at presentation, lesion location, chemical inactivation, surgical complications, tumor recurrence and pathological findings were explored. There were 28 females and 19 males, ranging in age from 17 to 78 years, with an average of 38.15 years. All the patients underwent surgical excision. Fourteen patients received intraoperative chemically inactive treatment. All the patients had routine follow-up to observe the wound healing, pathological findings,tumor recurrence, and received necessary imaging examinations.
Results: All the patients were followed up, and the duration ranged from 22 to 129 months, with a mean time of 53.89 months. Four patients who received intraoperative alcohol inactivation appeared wound complications such as wound swelling, discharge of necrotic tissue, delayed wound healing. Fifteen patients had active growth of tumor tissue, 1 patient had low-grade malignant giant cell tumor of tendon sheath. The recurrence rate was significantly higher in the group which preoperative X-ray was found to have bone destruction (P = 0.003); patients receiving chemically inactivation had lower risk of recurrence after surgery than patients not receiving chemically inactivation (P = 0.042).
Conclusion: The recurrence rate of giant cell tumor of tendon sheath in upper limb was closely related to tumor growth site, bone destruction and chemical inactivation. Local excision of giant cell tumor of tendon sheath was the effective treatment. How to identify the patients at high risk of recurrence, how to reduce the recurrence rate and the functional restoration after wide resection are the priorities and difficulties of future researches.

Undifferentiated pleomorphic sarcoma in the maxillary sinus: a case report.

Background: Undifferentiated pleomorphic sarcoma, previously called malignant fibrous histiocytoma, is a type of malignant mesenchymal tumor (sarcoma) of soft tissue and sometimes bone. It is uncommon in the oral cavity and very sporadic in the maxillary sinus. Microscopic diagnosis of this malignancy in the maxillary sinus can be very challenging, because there is a range of features that may overlap with other benign and malignant tumors.

Vision loss affects more than 7 million Americans and impacts quality of life, independence, social functioning, and overall health. Common and dangerous conditions causing sudden vision loss include acute angle-closure glaucoma, retinal detachment, retinal artery occlusion, giant cell arteritis, and optic neuritis. Acute angle-closure glaucoma features ocular pain, headache, and nausea; treatment includes pilocarpine eye drops, oral or intravenous acetazolamide, and intravenous mannitol.

The differential diagnosis of primary hyperparathyroidism can be considered clinically, biologically and radiologically. Clinically, primary hyperparathyroidism should be suspected in case of diffuse pain, renal lithiasis, osteoporosis, repeated fracture, cognitive or psychiatric disorder, or disturbance of consciousness. Nevertheless, the differential diagnosis of primary hyperparathyroidism is mainly biological, particularly in atypical forms, which must be differentiated from hypercalcemia with hypocalciuria or non- elevated PTH on the one hand, and from normo-calcemia with elevated PTH, hypophosphatemia or hypercalciuria on the other.

Perovskite technologies has taken giant steps on its advances in only a decade time, from fundamental science to device engineering. The possibility to exploit this technology on a thin flexible substrate gives an unbeatable power to weight ratio compares to similar photovoltaic systems, opening new possibilities and new integration concepts, going from building integrated and applied photovoltaics (BIPV, BAPV) to internet of things (IoT). In this perspective, the recent progress of perovskite solar technologies on flexible substrates are summarized, focusing on the challenges that researchers face upon using flexible substrates.
