Lymphadenitis due to toxoplasma infection is not uncommon and should be considered in the diagnosis of unexplained lymphadenopathy at all sites, especially at the cervical region. We report four cases of toxoplasmosis diagnosed by cytologic, histologic and serologic tests. Fine needle aspiration cytologic diagnosis can help the diagnosis of toxoplasma lymphadenitis and eliminate unnecessary hospitalization or surgery.

PURPOSE: To evaluate the surgical results and clinical characteristics of congenital lacrimal fistula. METHODS: Fourteen patients were diagnosed with congenital lacrimal fistula and received simple fistulectomy. Three patients received anterior lamella reposition operation simultaneously due to epiblepharon. We retrospectively reviewed the medical records and conducted telephone interviews. RESULTS: In 15 eyes of the 14 patients, epiphora through lacrimal fistula disappeared. Two eyes of 2 patients showed a little epiphora only outdoors but there was no need of further treatment. All patients accepted the surgical results cosmetically. Histologically, stratified squamous epithelial change with keratinization was remarkable by aging. In adults, hair follicles with increased keratinization were contained and the result with skin was similar. CONCLUSIONS: Simple fistulectomy was a useful technique for congenital lacrimal fistula.

PURPOSE: The purpose of this study was to evaluate the clinicopathological features and immunohistochemical features of gastrointestinal stromal tumor (GIST), and specifically the expressions of platelet derived growth factor receptor A (PDGFRA), protein kinase C theta (PKC theta), discovered on GIST-1 (DOG-1), p16 and p27. MATERIALS AND METHODS: Total 118 patients who underwent surgical resection for GIST at our institution between Jan 1997 and Dec 2007 were retrospectively studied. Immunohistochemical staining for c-kit, PDGFRA, PKC-theta, DOG-1, p16 and p27 was performed on a tissue microarray of the 118 GIST. The clinicopathologic parameters, the disease-free survival (DFS) and the overall survival rate were analyzed along with immunohistochemistry. RESULTS: The immunohistochemical stains for c-kit, CD34, PKC-theta, PDGFRA, DOG-1, p16 and p27 were positive in 89.8%, 72.0%, 56.8%, 94.9%, 90.7%, 69.5% and 44.1% of the tumor samples, respectively. The immunohistochemical expression of c-kit was strongly correlated with PKC-theta (p=0.000), DOG-1 (p=0.000) and CD34 (p=0.002). The DFS rate was significantly decreased for the patients with peritoneal GIST, high risk GIST, > or =10 cm-sized GIST, > or =10 mitoses/50 high power fields (HPFs) and p16 positivity (p=0.001, p=0.004, p=0.001, p=0.003 and p=0.028). GISTs > or =10 cm, epithelioid tumor cell type, and c-kit, and DOG-1 negativity were significantly associated with shorter period of overall survival (p=0.048, p=0.006, p=0.000 and p=0.000). CONCLUSION: The expression of p16 and no expression of c-kit and DOG-1 in GISTs, as well as peritoneal tumor site, high risk group, large tumor size, epithelioid tumor cell type and numerous mitoses, may be potentially prognostic factors for predicting worse outcome for patients who suffer from GIST.

PURPOSE: This study was carried out to accumulate basic data for nursing intervention development by evaluating the stress and emotional status of patients and their families after receiving hematopoietic stem cell transplantation (HSCT), illucidating and analysing related factors in order to decrease the negative effects of HSCT on their emotion. METHODS: Data were collected using a questionnaire to 53 HSCT patients and 50 families, who were older than 18 at tertiary-care institutions in Seoul, from January, 2000 to August, 2003. RESULTS: There was a significant score difference in stress (t=-2.302, p<0.05). Correlation between stress and emotional status was statistically significant (r=0.486, p<0.01; r=0, p<0.05). Economical burden of cost had significant effects on stress of patients (F=4.194, p<0.05). The series of emotional status of patients without jobs were higher (T=-2.583, p<0.05). The emotional status of families were influenced by monthly income (F=4.036, p<0.05) and patients' diagnosis (F=3.088, p<0.05). CONCLUSION: These results suggest that the cares for families should be considered with great concern as well as the ones for patients. In addition, such factors as economical burden by medical cost, monthly income and job status should not be excluded in transplantation nursing plans.

Ganglioneuroma is the most differentiated tumor of neural crest origin and rarely arises in the adrenal gland. Ganglioneuroma is typically known to be benign, but very rarely can metastasize to distant sites. We report a case of a 31-year-old man with a huge adrenal mass with hepatic metastases.

PURPOSE: Radiocontrast media are widely used in medical imaging to improve diagnostic accuracy. However, studies on the adverse reactions of radiocontrast media in children are limited. We aimed to describe the characteristics of adverse reactions to radiocontrast media among children who had a computed tomography scan or magnetic resonance imaging in a tertiary university hospital. METHODS: We retrospectively collected data on adverse reactions to radiocontrast media by the reporting system of a tertiary university hospital. We selected data from children under the age of 19 from July 2011 to December 2017 and analyzed their characteristics. We focused mainly on the characteristics of the index case which is defined by the first adverse event of each subject. RESULTS: During the period, a total of 88,050 radiocontrast media-enhanced imaging studies were performed and 184 cases of adverse reactions were reported. A total of 71 were identified as index cases. Forty-nine (69.0%) were male and the mean age was 12.7±3.2 years. The incidence of radiocontrast media-related adverse reactions was 0.09% and severe reactions were 0.002%. The most common clinical feature was skin manifestations (54.9%), followed by gastrointestinal symptoms (40.8%) and neuropsychiatric symptoms (7.4%). CONCLUSION: Adverse reactions to radiocontrast media rarely occur in children and the incidence of severe reactions is low. Most reactions are mild and are related to the skin and gastrointestinal system. This report would provide good evidence for establishing a management strategy in children scheduled for imaging studies using radiocontrast media.

PURPOSE: The tumor of lacrimal sac is very rare. We report an experience of a 63-year-old female who had a squamous cell carcinoma of the lacrimal sac and discuss its diagnosis and overall management. METHODS: A 63-year-old woman came to our clinic with a 2-month history of a growing mass in the region of the left medial canthus, left eye tearing. Examination revealed left epiphora and swelling on the left medial canthus and the left lacrimal sac, which was firm. Lacrimal irrigation indicated an obstruction. A computed tomographic scan demonstrated a well enhancing soft tissue mass in medial aspect of left orbit and no evidence of invasion of rectus muscles and adjacent bony destruction. The mass was excised by dacryocystectomy and subsequently, required 200 cGy a day, 5 times a week, 6000 cGy of radiotherapy for 6 weeks. RESULTS: The patient was finally diagnosed with keratinizing, squamous cell carcinoma that was proven by histopathologic finding. There was no evidence of recurrence of the tumor in lacrimal sac throughout 24 months of follow-up period.

PURPOSE: The aim of this study was to determine the survival rates of implants placed in grafted maxillary sinuses and compare the results obtained with graft materials, implant surfaces and timing of implant placement. MATERIALS AND METHODS: Between January 1996 and December 2005, 391 implants were placed in 161 patients who underwent sinus grafting treatment simultaneously or separately at Ewha Womans University Hospital. According to inclusion criteria, 272 implants were placed in 102 patients with 112 sinus grafts (30 females, 72 males), aged 26 to 88 years (mean age 49.0+/-9.7). The follow-up period ranged from 12 to 134 months (mean F/U 47+/-32). Survival rates were evaluated according to graft material, implant surface and timing of implant placement. The Kaplan-Meier procedure and the log rank (Mantel-Cox) test were used to estimate survival rates and test for equality of survival rates between different groups of patients. RESULTS: Ten-year cumulative survival rate for implants placed in the grafted sinuses was 90.1%. The survival rates for autogenous bone, combination and bone substitutes were 94.6%, 85.9% and 100%, respectively (p > 0.05). According to implant surface, survival rates were 84.8% in machined group and 97.5% in rough group (p < 0.05). The survival rates were 92.9% in delayed group and 86.0% in simultaneous group (p > 0.05). CONCLUSION: Ten-year cumulative survival rate for implants placed in the grafted sinuses was 90.1%. Rough-surfaced implants have a higher survival rate than machined-surfaced implants when placed in grafted sinuses (p < 0.05).
