Purpose: Despite the increasing number of patients with HIV (human immunodeficiency virus) infection, surgical experience with these patients remains limited in aesthetic and reconstructive surgery. The authors performed breast reconsruction with free TRAM (Transverse Rectus Abdominis Muculocutaneous) flap in HIV infected patient firstly in Korea. Methods: A 53-years-old female with HIV positive underwent delayed breast reconstruction with free TRAM flap and 6 months lateral nipple reconstruction was performed. All procedures were performed according to the HIV infection control guidelines provided by the Korea Centers for Disease Control and Prevention. Results: There were no complications such as infection, hematoma and flap loss and symmetry of breast was achieved. Conclusion: When the operation is performed in line with the guidelines of HIV infection control, breast reconstruction with free flap is possible and can obtain successful results.

The incidence of musculoskeletal tuberculosis (TB) is on the rise due to the current Acquired Immunodeficiency Syndrome (AIDS) pandemic. Spine is the most common osseous site, followed by other joints. TB identified in the elbow accounts for 2%-5% of skeletal TB cases, which are secondary to pulmonary TB. Primary elbow TB is rare. We report a case of primary TB of the elbow which had a negative synovial biopsy. A 46-year-old right-hand dominant female patient with chronic pain and disability of the right elbow was diagnosed with chronic non-specific arthritis based on an arthroscopic synovial biopsy. The case was diagnosed retrospectively as active TB from bone cuts post total elbow arthroplasty. Anti-tuberculosis treatment (ATT) was given postoperatively for 12 months. The patient reported good functional outcomes at 3 years of follow-up. Such atypical presentations of osteoarticular TB are challenging to diagnose. Therefore, particularly in endemic areas, clinicians should be careful before excluding such a diagnosis even after a negative biopsy. Further research should investigate whether active TB of small joints such as the elbow can be treated with ATT, and early arthroplasty should be a focus of this research.

Commercial lower limb prostheses or orthotics help patients achieve a normal life. However, patients who use such aids need prolonged training to achieve a normal gait, and their fatigability increases. To improve patient comfort, this study proposed a method of predicting gait angle using neural networks and EMG signals. Experimental results using our method show that the absolute average error of the estimated gait angles is $0.25^{\circ}$. This performance data used reference input from a controller for the lower limb orthotic or prosthesis controllers while the patients were walking.

A hearing aid performs the role of fitting in order to provide those with a hearing problem with a better hearing ability in ordinary circumstances. The existing Fitting system in the hearing aid is consisted somewhat complex, and simply performs the role of Fitting without any supervisions of those with a hearing problem. Such is these methods makes it unable to establish an organized supervision, and shows a problem in making high efficiency. In order to solve this problem mentioned as above, the based thesis have connected the Fitting program and the patient-management database program for the easy use by the user.

Herpes virus family is highly infectious to patients, their families and dentists. The diagnosis of herpes infection is based on the characteristic clinical appearance and the location of the lesions. Herpes Simplex Virus(HSV) usually acquired through direct contact with infected lesions or body fluids, and the prevalence of HSV infection increases progressively from childhood. Primary infections provoke herpetic gingivostomatis typically affects the tongue, lips, gingival, buccal mucosa and palate. Recurrent infections give rise to vesiculo-ulcerative lesions at vermilion border of lip(herpes labialis). In the form of chickenpox, Varicella Zoster Virus(VZV) usually is infected in childhood. VZV spreads in the affected primary afferent nerve to the skin and produces a vesicular rash and pain. Epstein-Barr Virus(EBV) infects B cells and cause infectious mononucleosis. Latent EBV infection has also been implicated in Burkitt lymphoma, nasopharyngeal carcinoma. Cytomegalovirus(CMV) is associated with immune-compromised patient such as organ transplantation and AIDS patients.

Twenty-two years old male was operated for spontaneous rupture of the esophagus. In the event of perforation, there is nothing to prevent wide spread dissemination, and a devastating necrotizing chemical insult occurrs which is rapidly complicated by anaerobic and aerobic infection which quickly jeopardizes the patient`s life, often with a fatal result. For these reasons and despite modern diagnostic aids, anesthetic and operative technics, and antibiotics, perforation of the esophagus is still an alarming accident. In this case, thoracotomy and surgical closure of the perforation resulted in satisfactory outcome except postoperative fistula, which healed spontaneously.

Velopharyngeal function refers to the combined activity of the soft palate and pharynx in closing and opening the velopharyngeal port to the required degree. In normal speech, various muscles of palate & pharynx function as sphincter and occlude the oropharynx from the nasopharynx during the production of oral consonant sounds. Inadequate velopharyngeal function caused by neurologic disorder - cerebral apoplexy, regressive diseases - disseminated sclerosis, Parkinson's disease, congenital deformity - cleft palate, cerebral palsy and etc. may result in abnormal speech characterized by hypernasality, nasal emission and decreased intelligibility of speech due to weak consonant production. In our study, we constructed speech aids prosthesis - Palatal lift in acquired idiophathic VPI patient and assessed velopharyngeal function with various diagnostic instruments which can evaluate the speech characteristics objectively.

Velopharyngeal function refers to the combined activity of the soft palate and pharynx in closing and opening the velopharyngeal port to the required degree. In normal speech, during the production of oral consonant sounds elevation of the soft palate, along with the superior constrictor muscle, occludes the oropharynx from the nasopharynx. Inadequate velopharyngeal function caused by congenital or acquired insufficiency or incompetency may result in abnormal speech characterized by hypernasality, nasal emission and decreased intelligibility of speech due to weak consonant production. The speech aid is often helpful in improving the speech of individuals with velopharyngeal incompetency. In this article, the pathogenesis and treatment of velopharyngeal incompetence are discussed and a speech aid appliance that was constructed for the patient is described.

Foreign bodies in the oral cavity and pharyngolarynx are frequently observed accidental cases in the otolaryngological fields. Most foreign bodies can be recognized and removable with the manipulation of endoscopes and various instruments. However, foreign bodies that penetrate the oral cavity and oropharynx to appear as a tongue mass are rare. Therefore, such cases easily can be misconceived as tongue tumor at first, so it must involve a more thorough search utilizing such aids as computed tomography. Depending on their location and size, their removal may involve surgical intervention. The authors experienced such a rare case of an elderly male patient, presenting as tongue mass. We hereby report this case along with the relevant literature.

Well-dying is as important as Well-Being because dying is also a natural part of life. Recently, due to the change of lifestyles, cancer, AIDS and other chronic diseases cause drastic increase of mortality rate. Needs for hospice services are growing as many terminal patients interested in quality of life during their end of life period. They want calm and dignity in case process as well as pain-relieving. However, there is not many researches on the architectural planning of hospice facilities and their service system as well as government regulations. This study focuses on the German hospice facilities which have developed advanced models through researches on service contents and architectural planning. The purpose of this study is to provide fundamental data for designing hospice facilities through analyzing 7 cases of German hospice facilities with different characteristics.
