Uni- or bilateral mandibular hypoplasia can be associated with various syndromes or is acquired after early traumatic or inflammatory disease in the temporomandibular joint(TMJ). Early treatment is necessary to avoid consequent impairment of midfacial growth. The standard treatment of these malformations consists of the application of bone grafts which can lead to unpredictable growth, but the new procedure of bone lengthening which was presented by McCarthy et al. represents a limited surgical intervention and therefore open up a new perspective of treatment, especially in younger children with severe deformities. Patients with hemifacial microsomia and facial asymmetry have a vertically short maxilla, a tilted occlusal plane, and a short mandible. A 14-years-old boy with facial asymmetry, who was fractured on both condyle and mandibular symphysis before 8 years ago, was treated by mandibular ramus lengthening, symphysial widening and surgically assisted rapid palatal expansion with corticotomy. After allowing 1 week for the healing of the periosteum, the distraction was performed at the rate of 0.5-1.0mm per day for 7 days on maxilla and 14 days on mandible. The device was maintained on maxilla and mandible for 12 weeks following distraction. The difference in ramus and mandibular transverse deficiency were corrected and facial asymmetry was improved with complex distraction osteogenesis.

PURPOSE: To explore the meaning of prayer in Korean patients with end-stage cancer who profess Christianity or Buddhism, given the significant differences between these religions. METHODS: The Colaizzi (1978) analysis method was employed. In-depth interview were performed with 13 participants (seven Christians and six Buddhists) who were admitted to a University-affiliated hospital in Korea. RESULTS: The six categories emerged: 1) communication with God, 2) mind discipline, 3) spiritual growth, 4) mysterious experiences, 5) perception of death and after-life, and 6) various forms of prayers. CONCLUSION: The participants' prayer experiences were described in a religious context. Christians believed that prayer is communication with God while Buddhists regarded it as disciplining of minds. Despite some differences between the religious groups, a general meaning of prayer was a desperate desire to solve their health issues by relying on God or someone who is more powerful than themselves. They also experienced personal and spiritual growth through prayer. This study explains the phenomenon of prayer experiences and shows that prayer is an important coping mechanism.

Cellular schwannoma is a variant of schwannoma, and is diagnosed as malignant tumor in over one fourth of cases because of its cellularity, mitotic activity and the occasional presence of bone destruction. This tumor is a tumor with low malignant potential and usually occurs in peripheral nervous system, mainly in the posterior mediastinum and retroperitoneal space. But pelvic retroperitoneal cellular schwannoma is very rare. Recently, we experienced a case of pelvic retroperitoneal cellular schwannoma in a 42-year-old woman; in reporting the case a brief review of the literature is included.

Bone marrow (BM) has been considered as a reservoir of stem/progenitor cells which are able to differentiate into ectodermal, endodermal, and mesodermal origins in vitro as well as in vivo. Following adequate stimulation, such as granulocyte stimulating factor (G-CSF) or AMD3100, BM resident stem/progenitor cells (BMSPCs) can be mobilized to peripheral blood. Several host-related factors are known to participate in this mobilization process. In fact, a significant number of donors are resistant to G-CSF induced mobilization protocols. AMD3100 is currently used in combination with G-CSF. However, information regarding host-related factors which may influence the AMD3100 directed mobilization is extremely limited. In this study, we were to get some more knowledge on the host-related factors that affect the efficiency of AMD3100 induced mobilization by employing in vivo mobilization experiments. As a result, we found that C57BL/6J mice are more sensitive to AMD3100 but less sensitive to G-CSF which promotes the proliferation of BMSPCs. We excluded S1P as one of the host related factor which influences AMD3100 directed mobilization because pre-treatment of S1P receptor antagonist FTY720 did not inhibit BMSPC mobilization. Further in vitro experiments revealed that BALB/c mice, compared to C57BL/6J mice, have less BMSPCs which migrate in response to host related factors such as sphingosine-1-phosphate (S1P) and to CXCL12. We conclude that AMD3100-directed mobilization depends on the number of BMSPCs rather than on the host-related factors. These results suggest that the combination of AMD3100 and G-CSF is co-operative and is optimal for the mobilization of BMSPCs.

Purpose:
This study was performed to evaluate the quality of life and genitourinary function after total mesorectal excision with lateral lymph node dissection compared to those after total mesorectal excision alone following neoadjuvant chemoradiotherapy for rectal cancer.
Methods:
Among patients who underwent rectal cancer surgery after completing neoadjuvant chemoradiotherapy between September 2011 and October 2018 at the National Cancer Center, Korea, patients who completed the validated questionnaires before initiation of neoadjuvant chemoradiotherapy and at 3 months and 1 year postoperatively were included in this study. The European Organization for Research and Treatment of Cancer (EORTC) core quality of life questionnaire (QLQ-C30), colorectal cancer-specific quality of life questionnaire (QLQ-CR38), and International Prostate Symptom Score (IPSS) questionnaire were used for collecting data.
Results:
The total mesorectal excision alone group and the total mesorectal excision with lateral lymph node dissection group included 52 and 38 patients, respectively. The second group included significantly younger patients (P = 0.024), had a higher incidence of clinical T4 stage disease (P = 0.033), estimated blood loss (P = 0.003), and longer operation time (P < 0.001). Significant differences were not observed between the groups with respect to the EORTC QLQ-C30, QLQ-CR38, and IPSS. Multivariable analysis showed that lateral lymph node dissection had no statistically significant association with postoperative urinary dysfunction (P = 0.953).
Conclusion
The overall quality of life and urinary function after total mesorectal excision does not differ significantly when lateral lymph node dissection is performed as well.

OBJECTIVE: The objective of this study was to examine the effect on development of mouse preimplantation embryos in culture media with different composition of energy sources in vitro culture. METHODS: Two hundred and seventy one two-cell embryos were cultured in four different culture system for 96 hours. Group I (n=61) was cultured in DMEM-G (DMEM with glutamine) only, groupII (n=64) was cultured in DMEM-GGP (DMEM with glutamine, glucose and pyruvate) only, group III (n=72) was cultured for 48 hours in DMEM-G and then transferred to DMEM-GGP and group IV (n=74) was cultured for 48 hours in DMEM-GGP and then transferred to DMEM-G. Development of embryos in each group was observed every 24 hours. RESULTS: After 24 hours, the rate of development > or = 3-cell was significantly higher in groupII (87.5%) and IV (86.5%) compared with group I (59.0%) and III (62.5%). After 48 hours, the rate of development into > or = morula stage was significantly higher in GroupII (79.7%) and IV (86.5%) compared with group I (34.4%) and III (37.5%). After 72 hours, the rate of development into blastocyst was significantly higher in group IV (74.3%) compared with group I (49.2%) and III (45.8%). After 96 hours, the rate of development into > or = expanded blastocyst was significantly higher in group IV (70.3%) compared with group I (32.8%),II (53.1%), and group III (40.3%). CONCLUSION: Mouse preimplantation embryos development was the most effective in culture system with DMEM-GGP for 48 hours and then transferred to DMEM-G.

Eosinophilic granulomatosis with polyangiitis (EGPA), previously called Churg-Strauss syndrome, is an anti-neutrophil cytoplasmic antibody associated vasculitis, accompanied by asthma, hypereosinophilia, nonfixed pulmonary infiltrates, and sinusitis. Peripheral neuropathy is common in patients with EGPA; however, a few cases of EGPA with central nervous system (CNS) involvement have been reported. A 45-year-old female referred for right side weakness and posterior neck pain was diagnosed as EGPA with subarachnoid hemorrhage and mononeuritis multiplex. She was effectively treated with a high dose glucocorticoid, cyclophosphamide, and intravenous immunoglobulin. EGPA with CNS involvement is uncommon and causes significant morbidity and mortality. Therefore more rapid and accurate diagnostic evaluation may be required. EGPA should be considered in patients with neurological symptoms and hypereosinophilia.
