Lupus nephritis is one of major complications of systemic lupus erythematosus, which determine the outcome of the disease. A case of lupus nephritis was admitted to our pediatric department and renal biopsy was done, which reveraled membranophroliferative type in electron-microscopy. He was treated with prednisone only and responded well in urinary findings. Now, he is maintained with low dose prednisone.

BACKGROUND: Oral mucositis during radiotherapy which is harmful to the patients with head and neck is suggested to be related to the oral hygiene and health. Therefore, we evaluated the oral health status in relation to the occurrence of mucositis among patients with head and neck cancer during radiotherapy. METHODS: Tooth plaque index (PI), periodontal depth, and oral mucositis in 50 patients with head and neck cancer were examined by a dentist for 8 weeks after radiotherapy initiation. Cancer type and site were recorded based on the patients’ medical records. In addition, we assessed oral health-related quality of life. RESULTS: The mean age of participants was 56.3 ± 11.6 years, with patients aged > 60 years comprising the largest proportion of the mucositis group. The median (range) of the PI index were 0 (0–3) and 1 (0–3) among participants with mucositis and those without, respectively, with no significant difference (P = 0.761). The median (range) of the total Oral Health Impact Profile score were 54 (42–58) and 41 (14–70) among participants without mucositis and those with mucositis, respectively (P = 0.037). CONCLUSIONS: This study showed that patients who developed mucositis during radiotherapy had lower oral health-related quality of life than those who did not. However, there was no difference in oral health status according to mucositis.

BACKGROUND: In the osseointegration of dental implants, the implant surface properties have been reported to be some of the most important critical factors. The effect of implant's surfaces created by resorbable blast media (RBM) followed by laser ablation on bone tissue reactions was examined using the removal torque test and histomorphometric analysis.METHODS: Two types of dental implants, RBM-laser implants (experimental group) and RBM implants (control group) (CSM implant system, Daegu, Korea; L=6 mm, diameter=3.75 mm) were placed into the right and left distal femoral metaphysis of 17 adult rabbits. Six weeks after placement, removal torque was measured and histomorphometric analysis was performed.RESULTS: The mean removal torque was 24.0±10.2 Ncm and 46.6±16.4 Ncm for the control and test specimens, respectively. The experimental RBM-laser implants had significantly higher removal torque values than the control RBM implants (p=0.013). The mean values of total and cortical bone to implant contact (BIC) were respectively 46.3±10.8% and 65.3±12.5% for the experimental group, and 41.9±18.5% and 57.6±10.6% for the control group. The experimental RBM-laser implants showed a higher degree of total and cortical BIC compared with RBM implants, but there was no statistical significance (p=0.482, 0.225).CONCLUSION: The removal torque and BIC of the test group were higher than those of the control group. In this study, the surface treatment created by RBM treatment followed by laser ablation appears to have a potential in improving bone tissue reactions of dental implants.

Though extremely rare, teratoma must also be considered in the differential diagnosis of abdominal mass in the first year of life. The kidney is among the least frequent of the various anatomic location in which teratoma and other germ cell tumors have been reported. One of the earliest cases reported by McCurd(1934) in a 7 week old male with multiple anomalies. The intrarenal teratoma simulated nearly all of the preoperative features including the roentgenographic findings of Wilm's tumor. A histologic examination was required to reverse the clinical and operative impression. We report an anesthetic experience of a 3 month old infant with hypertension being admitted to our hospital with the chief complaint of abdominal mass, which was clinically diagnosed as Wilms' tumor. However postoperative pathologic diagnosis was found to be intrarenal teratoma.

OBJECTIVES: The aim of this study was to assess the change in oral health-related quality of life among patients with head & neck cancer who received radiotherapy. METHODS: A total of 40 patients who were diagnosed as having head and neck cancer and scheduled to have radiotherapy were enrolled in this study; however, only 25 patients were included in the final analysis. Prior to radiotherapy, a dentist performed an oral examination to check for the presence of decayed and missing teeth, plaque, and determine the gingival index. Oral health-related quality of life was assessed using the OHIP-14 questionnaire. Eight weeks after starting radiotherapy, oral health-related quality of life was re-evaluated using the same questionnaire. RESULTS: The mean age of the participants was 60.20 (±7.29) years, and 22 (88.8%) of them were men. The majority of the participants were diagnosed as having squamous cell carcinoma (68.0%). The total OHIP-14 score was significantly decreased from 56.20 (±13.50) at baseline to 45.72 (±10.98) eight weeks after radiotherapy. In addition, according to subjective oral health at baseline, the observed change in the OHIP-14 score was significantly different. CONCLUSIONS: Oral health-related quality of life was significantly lowered after radiotherapy in patients with head and neck cancer.

Potocki-Shaffer syndrome (PSS, OMIM #601224) is a rare contiguous gene deletion syndrome caused by haploinsufficiency of genes located on the 11p11.2p12. Affected individuals have a number of characteristic features including multiple exostoses, biparietal foramina, abnormalities of genitourinary system, hypotonia, developmental delay, and intellectual disability. We report here on the first Korean case of an 8-yr-old boy with PSS diagnosed by high resolution microarray. Initial evaluation was done at age 6 months because of a history of developmental delay, hypotonia, and dysmorphic face. Coronal craniosynostosis and enlarged parietal foramina were found on skull radiographs. At age 6 yr, he had severe global developmental delay. Multiple exostoses of long bones were detected during a radiological check-up. Based on the clinical and radiological features, PSS was highly suspected. Subsequently, chromosomal microarray analysis identified an 8.6 Mb deletion at 11p11.2 [arr 11p12p11.2 (Chr11:39,204,770-47,791,278)x1]. The patient continued rehabilitation therapy for profound developmental delay. The progression of multiple exostosis has being monitored. This case confirms and extends data on the genetic basis of PSS. In clinical and radiologic aspect, a patient with multiple exostoses accompanying with syndromic features, including craniofacial abnormalities and mental retardation, the diagnosis of PSS should be considered.
