Many articles on operative treatment strategies for osteochondral lesions of the talus (OLT) have been published. On the other hand, there are only a few reports on the conservative treatment of OLT. Understanding the natural history of OLT is essential to establishing the correct treatment. Conservative treatment might lead to comparable clinical outcomes compared to the current options of the operative treatment in isolated OLT lesions. OLT lesions can be divided into two (or possibly three) types. Hence, the prognosis and outcome of certain operative treatments should be evaluated further. The prognosis of OLT combined with instability or malalignment appears poorer than that of isolated OLT lesions. Therefore, concomitant pathologies should be evaluated together when treating patients with OLT.

Purpose: This study compared the SLAP lesions caused by a sports-induced injury with those caused by a non-sports-induced injury. Materials and Methods: The study was performed on 54 patients who had undergone arthroscopic surgery for a SLAP lesion. There were 21 sports-induced-injury patients (group I) and 36 non-sports-induced injury patients (group II). The mean age of the men was 36 years and that of the women was 48 years. In both groups, the frequency of a concomitant injury and the clinical outcomes at the last follow-up was evaluated using the UCLA score, Rowe score, and the ASES score. Results: According to their injury mechanism, , there were 14 cases (67%) of repeated microtrauma injury in group I and 25 cases (75%) of compression injury type in group II. As a concomitant pathology, there was 11 cases of shoulder instability and 5 cases of a rotator cuff tear in group I, and 23 cases of rotator cuff tears and 14 cases of shoulder instability in group II. At the last follow up, group I showed slightly better clinical satisfaction (P>0.05). Conclusion: The possibility of a SLAP lesion accompanying other diseases is high. Therefore, an accurate assessment of concomitant injury lesions before surgery is important for the treatment outcome.

Posterior capsular tightness with glenohumeral internal rotation deficit is usually considered to be an acquired condition of the throwing shoulder and is usually treated conservatively. However, because posterior capsular tightness is sometimes irreversible, we have performed arthroscopic capsular release for painful throwing shoulder with posterior capsular tightness. The true loss of internal rotation and posterior stiffness was confirmed by examination with the patient under anesthesia, and contracture of the posterior capsule and the posterior band of the inferior glenohumeral ligamant was observed arthroscopically. Because an extensive adhesion between the capsule and the fascia of the external rotators was noted, a capsular release was performed from 6 o'clock to 11 o'clock (in the right shoulder) to completely expose the muscle belly of the external rotators. Of the first 16 consecutive patients, 4 had no concomitant lesions and underwent posterior capsular release alone. With a minimum of 2 years' follow-up, it was ascertained that the throwing pain completely disappeared in 14 patients and improved in 2. In all, 11 patients returned to their preinjury performance level, and 5 returned to a lower level of function. In the 4 patients who had no concomitant lesions, throwing pain completely disappeared, and all were able to return to their preinjury performance level.

Pemphigus vulgaris is a rin, chronic intraepidermal bullous disease with potentially fatal outcome. Oral lesions precede skin lesions in at least $70\%$ of cases, and in cutaneous disease, concomitant oral lesions are encountered in $90\%$ of patients. This disorder involve the skin and mucous membranes, especially the oral and pharyngeal mucosa, but may also involve the nasal, oropharyngeal, laryngeal and esophageal mucosa. Oral lesions are initially vesicobullous but rapidly rupture, leaving a painful erosion that shows little tendency to heal. Pemphigus vulgaris affecting the oral mucosa is still diagnosed only after considerable delay, because oral ulceration in common, and clinicians believed the lesions to be caused by more common conditions such as recurrent aphthous stomatitis rather than a rare disorder such as pemphigus vulgaris. The definitive diagnosis of pemphigus vulgaris should be undertaken as early as possible, so that treatment can be started at an earl·y stage. Because of the presence of nonspecific oral ulcer, high degree of suspicion is often required to ultimately make the diagnosis of pemphigus vulgaris and then we report a case of pemphigus vulgaris with a literature review.

Eight patients with proven clinical stage Ill lung carcinoma of which six were epidermoid cell carcinoma and two were small cell carcinoma underwent concomitant radiation therapy and chemotherapy before surgical resection from March 1990 to February 1992 at the thoracic surgical department, Yongdong Severance Hospital, Yonsei University College Medicine The therapy consisted of more than one cycle of chemotherapy every 4 weeks and concomitant irradiation. Three to four weeks after chemotherapy and radiation therapy, the patient were reevaluated for thoracotomy and pulmonary resection. Two patients were found to have unresectable lesions and, radiosotopes were implanted to the remaining tumors. Three patients had complete pneumonectomies and two patients had pericardial penumonectomyo. Only one patient had complete pneumonectomy & concomitant resection of ribs attached to tumors with reconstruction of chest wall with Marlex mesh. Complete sterilization of lung tumor and mediastinal nodes proven histologically was achieved in 2 patients, without operative mortality. The median survival of all patients was eight months, but the median survival of survivors which lung tumor were completely resected completely and whose pathologic reports showed stage I or 0, was about 18 months to now. The overall result indicates some benefit from this preoperative chemotherapy and radiation therapeutic regimen in patients with advanced unresectable lung cancer.

Bony lesions of the glenoid and Hill-Sachs lesions are the most common injuries after a first-time traumatic shoulder dislocation. However, fracture of the coracoid process after traumatic shoulder dislocation is rare. A single, open surgical procedure could be performed by a Latarjet procedure using a fractured fragment of the coracoid process. If a fracture of the coracoid process is associated with a traumatic anterior shoulder dislocation, the Latarjet procedure may be the most appropriate surgical option.

Purpose: Chronic inflammatory gingival lesions occur as pyogenic granulomas or non-specific chronic suppurative lesions. Methods: Of the 59 chronic inflammatory gingival lesions examined, plasma cell granuloma (n=14), which showed an intense antibody-mediated immune reaction with the increased infiltration of plasma cells, was observed as a pseudotumor-like gingival overgrowth and myofibroblastic or fibrohistiocytitc proliferation of stromal cells with a heavy collection of plasma cells. The levels of CD3, CD20, CD31, CD68, RANKL, cathepsin G, cathepsin K, lysozyme, TNF${\alpha}$, MMP-2, and MMP-9 in the 14 cases of gingival plasma cell granuloma with immunohistochemical detection were measured to determine the pathogenetic progresses of the plasma cell granuloma compared to the common pyogenic granuloma (n=45) in the gingiva. Results: The gingival lesions of the plasma cell granuloma could be divided into three histological types, plasma cell predominant type (PPT, n=8), mixed inflammatory cell type (MICT, n=2), and sclerosed fibrosis type (SFT, n=4). The PPT showed a condensed infiltration of plasma cells into the perivascular spaces of the granulomatous lesion with frequent formation of Russel's body in their cytoplasm. The MICT showed the concomitant infiltration of many macrophages together with plasma cells, resulting in the diffuse destruction of stromal fibrous tissue. The SFT showed granulomatous lesions replaced gradually by thick collagenous fibrous tissue, resembling an inflammatory pseudotumor. The SFT expressed strongly the lymphocytic markers, CD3 and CD20, and the macrophage/monocyte markers, CD31 and CD68, but showed reduced expression of common inflammatory markers, TNF${\alpha}$, cathepsin G, lysozyme, MMP-2, and MMP-9, as well as the reduced expression of osteoclastogenic markers, RANKL and cathepsin K. Conclusion: These results suggest that a gingival plasma cell granuloma shows variable gene expression for cell-mediated immunity and stromal tissue degeneration, undergoing sclerotic fibrosis with a persistent inflammatory reaction.

Objective : In selected cases, the transsphenoidal approach[TSA] can be extended anteriorly to the tuberculum sellae, chiasmatic sulcus, and planum sphenoidale to obtain direct exposure of the suprasellar cisterns and its contents. We applied this modification of the TSA to various lesions of the presellar and suprasellar areas. We evaluate our clinical experience of this technique and review the related literature. Methods : From 1999 to 2004, we used the transsphenoidal supradiaphragmatic intradural approachs[TSIAs] in 9 patients who had various lesions at the pre- and suprasellar regions. Concomitant presellar extension of the bone window was performed with the sublabial or transnasal transseptal transphenoidal techniques. After removal of the lesions, sellar or anterior cranial floor was repaired with silicone plate substitute. Results : The TSIAs have been applied in the following cases : four tuberculum sellae meningiomas, two craniopharyngiomas, two Rathke's cleft cysts, and one non-functioning macroadenoma. The complications were one case of visual acuity decrease and one cerebrospinal fluid rhinorrhea. Conclusion : The TSIA is easily applicable through a minor modification of the standard TSA. It is suitable for removing lesions located in the presellar and suprasellar area adjacent to the pituitary stalk with minimal brain manipulation and decreased morbidity.

Aim: To report the results of radiotherapy with or without chemotherapy in the patients with oral cancer. Methods: Over the 2003-2009 periods, a total number of 69 patients with squamous cell carcinoma of the oral cavity that refused surgery or had unresectable tumor were enrolled in this study. A total dose of 60 to 70 Gy (2 Gy per day) was given to the primary tumor and clinically positive nodes. In the patients with locoregionally advanced disease (57 patients with $T_3$, $T_4$ lesions and/ or $N^+$) induction chemotherapy following by concomitant chemoradiation was used. Induction chemotherapy consisted of 3 cycles of Cisplatin and 5-Flourouracil with or without Docetaxel. Weekly cisplatin was used in concomitant protocol. Kaplan-Meier method was used to calculate overall survival. Log-rank test and Cox regression model were used for comparison purposes. Results: Median follow-up was 32 months. The mean age of the patients was 59.2 years. The overall response rate after induction chemotherapy was 68.4%. Actuarial overall survival rates after 2 and 3 years were 38% and 26%, respectively. Clinical stage emerged as the only independent predictor of survival. Conclusion: Outcome of the patients with oral cancer is poor. Presenting with an advanced stage lesion contributed to this result. The role of chemotherapy in advanced cases remains to be defined.

Chronic granulomatous disease (CGD) is a rare inherited disorder caused by defective nicotinamide adenine dinucleotide phosphate oxidase enzyme and characterized by recurrent bacterial and fungal infections. Although liver abscess is a common manifestation of CGD, its management in CGD patients is not well-defined. In addition, the generalized guidelines for treating liver abscesses do not necessarily apply to CGD patients. Corticosteroids are commonly used to control granulomatous complications, such as inflammatory gastrointestinal and genitourinary lesions, in patients with CGD, Corticosteroids have also been used in combination with antimicrobials to treat refractory infections in patients with CGD. Because corticosteroids are capable of suppressing symptomatic inflammation, all potential infections must be adequately controlled prior to corticosteroid initiation. We report 3 typical CGD cases with liver abscesses refractory to conventional treatments that were successfully treated with the concomitant use of corticosteroid and antimicrobials. It remains unclear whether corticosteroid therapy is required for liver abscesses in CGD refractory to conventional treatments. However, based on our observations, use of corticosteroids in combination with optimal antimicrobials should be considered for refractory liver abscesses in CGD.
