A review of 50 patients with primary mediastinal tumors or cysts has been done to evaluate clinical and pathological behavior of this heterogeneous group of tumors proved by either excision or biopsy from January 1980 to August 1989 at the cardiovascular department of surgery in Kyungpook National University Hospital. There were 30 males and 20 females in this series. The ages of patients ranged from 4 months to 64 years. The mean age of subjects was 30.4 years. Neurogenic tumors [14 cases, 28%] and teratoma [14 cases, 28%] were most frequently encountered and followed by thymoma [10 cases, 20%] and benign cysts [4 cases, 8%]. The anatomic location of the primary mediastinal tumors or cysts was classified as anterior mediastinum and middle or visceral mediastinum and paravertebral or costovertebral mediastinum on the basis of the Shields’ proposition. In 32 patients[64%], the tumors or cysts were located in anterior mediastinum and in 13 patients[26%], the tumors or cysts were located in paravertebral or costovertebral mediastinum. And the rest 5 patients[10%] had middle or visceral mediastinal tumors or cysts. One of the characteristic features of primary mediastinal tumors or cysts is that some mediastinal tumors or cysts have their own preferred location in the mediastinum. In our series, all of the 14 patients with teratoma and 10 patients with thymoma had the anterior mediastinal location, while 13 of the 14 patients with neurogenic tumors had the paravertebral mediastinal location. 14 patients[28%] were asymptomatic and they all were discovered via so-called “Routine” chest x-ray examination. 39 of 50 patients[78%] were benign. 11 patients[22%] were malignant and they were all symptomatic. 40 patients[80%] were treated with complete resection. 5 patients[10%] were treated with partial resection : 2 of malignant thymoma, 3 of lipoma, neuroblastoma, primary squamous cell carcinoma. The rest 5 patients[10%] were only biopsied: 2 of undetermined malignancy and 3 of hemangioma, lymphoma, primary squamous cell carcinoma. 4 of the 10 patients were treated with combination of irradiation and chemotherapy. Postoperative complications were as followings: Horner’s syndrome [4cases, ado], respiratory failure [3 cases, 6%], pleural effusion[3 cases, 6%], Wound infection[2 cases, 4%] and bleeding, pneumothorax, empyema. There were 5 postoperative deaths [10%]. One patient with neuroblastoma died from intraoperative massive bleeding, 3 patients died early postoperatively from respiratory failure with undetermined malignancy died late postoperatively from congestive heart failure due to direct invasion of the tumor to the heart.

Objectives: The purpose of this study is to evaluate the treatment efficacy of enucleation after decompression. Materials and Methods: A total of 17 patients with cystic lesion of the jaw were treated with decompression followed by enucleation. Pre- and post-decompression panoramic radiographs were analyzed. Results: The mean percentage of reduction after decompression was 64%. The reaction was graded as good (>80%) in five patients (29.4%), moderate (50%-80%) in nine patients (52.9%), and poor (<50%) in three patients (17.6%). The reduction rate of larger cystic lesions was faster than that of smaller lesions. However, the reduction rate was not affected by age. The duration of follow-up ranged from one to eight years. There were no complications, and one case recurred. Conclusion: Decompression is an effective method for the initial treatment of jaw cysts.
A retrospective analysis was performed on 36 patients with primary cysts and tumors of the mediastinum seen at the Department of Thoracic and Cardiovascular Surgery of Maryknoll Hospital from January 1983 to December 1993. There were 21 female and 15 male patients in the study. Ages ranges from 2 years to 72 years, with a mean of 34.7. There were 9 malignant tumors and 27 benign tumors.Thymic neoplasms were the most common. For the whole series, 29 of the patients had tumors in the anterior mediastinum. There appears to be an in6rease in tumors in the anterior compartment. There were 30 symptomatic patients in our series. Of the patients with malignant disease, 89 % were symptomatic. All of benign tumors were completely removed and malignant tumors were treated with chemotherapy and radiotherapy after operation. There were 9[27.3 %] postoperative complications. There was no postoperative mortality. Follow-up was available on 27 patients. There was no recurrence, malignant degeneration, or growth of any tumor. It is hoped that careful evaluation and aggressive treatment of mediastinal tumors will continue to provide improvement in the prognosis for these patients.

Deep neck infection (DNI) is a potentially serious pathology that can lead to serious complications and high rate of mortality. Since DNI affects the cervical spaces, which can compromise airway, aggressive antibiotic administration and prompt surgical drainage are essential for recovery. Although most causes of DNI are known to be dental infections, developmental cysts such as dentigerous cysts are relatively few causes. In this case, we report a rare patient with severe deep neck space infection caused by infected third molar with dentigerous cyst.
Background and Objectives: In most cases of benign neck cysts, surgical excision has been considered as treatment of choice. However, sometimes complete excision is very difficult, and recurrences has been occured due to insufficient surgery frequently. In this point of view, non-surgical treatment has been attempted with sclerosing agents such as picibanil(OK-432). In this study, we evaluated the efficacy of picibanil sclerotherapy for benign neck cysts. Materials and methods: We retrospectively reviewed 53 patients(27 males, 26 females) who had undergone sclerotherapy with picibanil for benign neck cysts such as ranula, lymphangioma, thyroglossal duct cyst and branchial cyst. Information was gathered with respected to age, sex, number of injections, side effect and outcome of treatment. All patients were treated with intralesional aspiration of cystic contents and injection of picibanil, and followed on neck ultrasonography or neck CT. Results: 53 patients received sonoguided sclerotherapy using picibanil(OK-432). 31 patients(41.3%) showed total shrinkage, near total shrinkage(more than 90% of volume) in 7 patients(9.3%), marked shrinkage(more than 70%) in 5 patients(6.6%) and partial shrinkage(less than 70%) in 17 patients. 15 patients(20%) reaveled no response and 8 patients showed recurrences with repeated sclerotherapy. The side effects of therapy were observed by symptoms such as fever, localized pain and odynophagia. However, these complications disappeared after several days in all cases. Conclusions: We recognized that picibanil(OK-432) sclerotherapy for benign neck cyst is a safe and effective procedures as a primary treatment before considering surgery.
Pneumatocele (PC) is a thin-walled cyst of the lung that can occur at all ages and with various etiologies. However, there is no fully accepted consensus for the management of PC in a neonatal intensive care unit. Although the management of PC is generally expectant, it is difficult to decide how long conservative management should be maintained, especially under Korea's medical care environment and the parents' worry and anxiety. We report a male neonate, born at $27^{+5}weeks$ gestation, weighing 1,000 g, who had a post infectious PC caused by methicillin-resistant Staphylococcus aureus sepsis. We treated conservatively for about 100 days (roughly 14 weeks), but unfortunately after a few days of chest retraction, acute exacerbation occurred, video assisted thoracoscopic surgery (VATS) was deemed necessary and performed. The purpose of this publication is to describe the clinical course, aggravation and relief after VATS management with a review of the literature.
This clinical study was made of 214 cases of the jaw cysts which were diagnosed histopathologically in the Department of Oral and Maxillofacial Surgery, Wonkwang University Dental Hospital from Jan. 1, 1991 to Dec. 31, 1998. Medical records, radiographs, histopathological reports of 214 cases with jaw cysts were retrospectively reviewed. The results were as follows : 1. Among the total patient of 214 cases, male were 143 cases, and female are 71 cases, male predominated by the ratio of 2.04. 2. The periapical cysts and the dentigerous cyst are the most common cyst, irrespective of 116 cases(54.2%) and 58 cases(27.1%). 3. The periapical cyst has no gender prediction, male were 70 cases and female were 54 cases, the mean ages were 39.3 years(SD=18.4). The most common involving teeth were maxillary anterior teeth(59.7%). 4. The dentigerous cyst predominantly occurred in third decade (18 cases : 31%), and the mean ages were 31.9 years(SD=14.8). Dentigerous cysts predominantly occurred in male by the ratio of 7.29 (male : 51 cases, female : 7 cases). Maxillary anterior teeth(43.1%) and mandibular molars(32.8%) were most frequently involved. 5. The odontogenic keratocyst predominantly occurred in second and third decade and mean ages were 23.5 years(SD=17.2). The mandibular molars(60%) were most frequently involved. 6. All nasopalatine cyst occurred after fourth decade, mean ages were 49.5years(SD=10.4). In the gender incidence of nasopalatine cyst, 1 case occurred in female and 10 cases occurred in male. 7. In the surgical intervention of jaw cyst, cyst enucleation and marsupialization performed in 156 cases. Cyst enucleation with bone graft performed in 58 cases and iliac autogenous bone grafts most frequently performed in 29cases. 8. The diameter range of cyst enucleation with bone graft were from 15mm to 120mm with a cyst diameter of 33.3mm. (SD=15.2) The diameter range of cyst enucleation and marsupialization were from 7mm to 82mm with a cyst diameter of 20.4mm.(SD=9.0) The diameter of cyst enucleation with bone graft were significantly greater than diameter of cyst enucleation. (p<0.05) 9. Post-operative complications occurred in 9 cases(15.5%) in which cyst enucleation with bone grafts performed and occurred in 31 cases(19.9%) in which cyst enucleation.

Purpose: McCune-Albright syndrome (MAS) is caused by activating mutations in the GNAS gene, resulting in peripheral precocious puberty, caf$\acute{e}$-au-lait spots, and polyostotic fibrous dysplasia (POFD). The aim of the present study was to describe the diverse clinical and endocrine characteristics of patients with MAS. Methods: Seven patients with MAS were included in this study and medical charts were reviewed retrospectively for following parameters: patient's sex and age at diagnosis, POFD, ovarian cysts, and precocious puberty. Results: The mean age at diagnosis was $5.8{\pm}4.2$ years. One patient was male (14%) and the other six patients were female (86%). Peripheral precocious puberty was associated with 6 patients (86%). Five patients manifested premature menarche as early as 2 to 5 years of age. Letrozole was administered to 4 patients, tamoxifen to one patient and GnRH agonist to one patient. Five females developed ovarian cysts. Thyroid function tests were performed in all patients and one patient showed hyperthyroidism (14%) and has been treated with methimazole. One patient presented with pseudohypoparathyroisdism, phosphaturia, calciuria suggesting hypophosphatemic rickets. Six patients (86%) revealed POFD. One patient had symptoms of optic nerve compression and secondary esotropia and 2 patients had bone pain. Conclusion: This study described clinical characteristics and endocrine complications of patients with MAS. Careful physical examinations with history taking and serial endocrine function tests should be needed to detect complications such as endocrinologic hyperfunction and POFD.

One or two mesiodens are mostly common to the clinician. However, three mesiodens is rarely found and can cause complications such as orthodontic problems or interruptions of the adjacent teeth with more than 1 or 2 mesiodens. Many factors cause irregularities in the permanent dentition. Mesiodens, especially in the anterior maxilla, can disturb the eruption of adjacent permanent teeth and cause diastemas, ectopic eruptions, root resorption, or the formation of dentigerous cysts. The early diagnosis of mesiodens is important for preventing such complications, and the timing of intervention should be based on their location and number. Periodic checkups and improved diagnostic devices make it easy to find mesiodens and associated complications. In this case, 3 supernumerary teeth in the maxillary anterior region were affecting the eruption of the adjacent permanent incisors. To minimize complications and preserve the deciduous teeth, the three supernumerary teeth were extracted in 2 steps. Since cone-beam computed tomography was not available, a brace wire was used to measure the depth of the mesiodens.
The prevalence of Sarcocystis spp. was investigated by gross and histopathological examinations in 250 camels (Camelus dromedarius) slaughtered from 2002 to 2005 in the Mashhad Slaughterhouse, eastern Iran. Samples were taken from the diaphragm, heart, tongue, esophagus and masseter muscles for histopathological studies. No macroscopic sarcocysts were found in the samples at gross inspection. Sarcocysts were detected in 209 of 250 (83.6%) examined camels at histopathological level. The infection rate of the esophagus, heart, masseter muscles, diaphragm, and tongue was 58.8%, 48.0%, 46.8%, 41.6%, and 28.0%, respectively. There was no significant difference in the rate of infection between male (85.8%) and female (81.0%) camels. The tissue response to vital cysts was minimal; however, reaction to the degenerating cysts was severe and caused tissue damages resulting in hyperemia, hemorrhages, mononuclear cell infiltration, necrotic changes, and fibrosis. The wild and domestic carnivores especially dogs may be the final hosts of Sarcocystis spp. in this area.
