Rotator cuff tear is a common reason for shoulder pain. Although the surgical technique of rotator cuff repair is developing, high retear rate requires additional supplementary methods. Among these supplementary methods, as a kind of biologic augmentation, platelet-rich plasma (PRP) has been spotlighted and has recently been studied by many researchers. PRP, a concentrate of platelet extract obtained from whole blood, contains numerous growth factors. As this is known to play an important role in the tissue recovery process, it had been used for research in a variety of fields including orthopedics. Use of PRP has been attempted in surgical treatments of rotator cuff tear for better results; however, only a few large-scale research studies on the effect of PRP have been reported. Clinical results of each study are also variable. Therefore research using large-scale randomized, double-blind trials should be conducted in order to prove the application range, safety, and clinical effects of PRP.

Tinnitus is a perception of sound without external stimuli. The increase of noise from industrialization, complex psychological state, increase of old age people, and excessive medication make tinnitus a more common disease than ever before. However, the knowledge regarding diagnosis and treatment of tinnitus is still limited. Tinnitus can be categorized into paraauditory tinnitus and sensory neural tinnitus. Paraauditory tinnitus may occur from the sound generated by the vessel near the ear such as an arteriovenous fistula, abnormal vessel, a tumor around vessel, palatal myoclonus, and patent E tube. Sensory neural tinnitus can arise from senile hearing loss, noise-induced hearing loss, sudden deafness, sensorineural hearing loss associated with chronic otitis media, excessive medication, and so on. But there are many cases in which the specific cause cannot be defined. Diagnosis needs thorough history taking, physical examination, and radiologic and audiologic examination. Treatments for the paraauditory tinnitus are vessel ligation or coil embolization of arteriovenous fistula and removal of the causative factors. Although there are many treatment modalities for managing sensory neural tinnitus, a standardized treatment modality has not been established. Sensory neural tinnitus can be managed with tinnitus retraing therapy and electrical stimulation therapy. Although tinnitus is essentially not a life-treatening disease, advancing quality of life and the increasing number of patients with tinnitus mandate health-care providers to be more concerned with the disease tinnitus.

Surgery is the only hope to cure gastric cancer. The aim of surgery is the complete removal of the tumor (UICC RO-resection), which is known to be the only treatment modality proven effective and the most important treatment-related prognostic factor. The type of surgical treatment for gastric cancer is determined by the patient's medicosurgical status and the stage of disease. Improved survival and quality of life(QOL) are the major criteria for the therapeutic strategy. For patients with early gastric cancer, minimal invasive surgery is attempted for the improvement of QOL. Minimal invasive surgery can be performed only when there is no evidence for residual disease, especially in lymphnodes. Therefore, precise prediction and selection of node-negative patients is important for the application of minimal invasive surgery. However, long-term survival data are needed for these new techniques to become more generally accepted. For patients with advanced gastric cancer, aggressive and extended surgical approaches are recommended for the improvement of survival. Distal subtotal gastrectomy is the procedure of choice whenever tumor-free margin can be obtained, with the exception of proximal tumors that can be treated by total gastrectomy. Extended lymphadenectomy should be the choice of lymphadenectomy for experienced surgeons with a low morbidity and mortality. If a surgeon can perform combined resection of adjacent organs safely, it is recommended when a direct invasion is suspicious. Distal pancreatectomy should be avoided unless direct invasion is definite. Splenectomy for the purpose of lymph node dissection is be mandatory, and surgeons should consider preservation of the spleen when there is no definite splenic hilar lymph node enlargement or any direct invasion to the spleen. Cytoreductive surgery with intraperitoneal chemotherapy is a useful and promising procedure for the treatment of peritoneal metastasis. The therapeutic approach should be stratified according to the patient's status, tumor status,and QOL after resection. Above all, the treatment strategy should be specific and tailored to each patient for the improved survival and QOL.
