PURPOSE: We performed an immunohistochemical study with pre-treatment biopsy specimens to evaluate the prognostic significance of four biomolecular markers which can be used as a predictive assay for radiotherapy (RT) treatment of nasopharyngeal carcinoma (NPC). MATERIALS AND METHODS: From January 1998 through December 2006, 68 patients were histologically diagnosed as non-metastatic NPC and treated by RT. Only 38 patients had the paraffin block for the immunohistochemical study. Thirty-one patients had undifferentiated carcinoma and 7 patients had squamous cell carcinoma. Thirty-two patients (84%) had advanced stage NPC (2002 AJCC Stage III~IV). Immunohistochemical staining was performed for Met, COX-2, nm23-H1, and epidermal growth factor receptor (EGFR) expression using routine methods. RESULTS: The median follow-up time was 30 months (range, 11 to 83 months) for all patients, and 39 months (range, 19 to 83 months) for surviving patients. The 5-year overall survival (OS) rate of the patients with high Met extent (> or =50%) was significantly lower than that of the patients with low Met extent (48% vs. 84%, p=0.02). In addition, Met extent was also a significant prognostic factor in multivariate analysis (p=0.01). No correlation was observed between Met extent and T stage, N stage, stage group, gender, age, and the response to chemotherapy or RT. Met extent showed moderate correlation with COX-2 expression (Pearson coefficient 0.496, p<0.01), but COX-2 expression did not affect OS. Neither nm23-H1 or EGFR expression was a prognostic factor for OS in this study. CONCLUSION: High Met extent (> or =50%) might be an independent prognostic factor that predicts poor OS in NPC treated with RT.

VAHS is characterized by viral-like prodromal symptoms, high fever' malaise, hepatosp lenomegaly, pancytopenia. The dignosis is based on a bone marrow biopsy specimen that demonstrates histiocytic hyperplasia with prominent hemophagocytosis of red blood cells, platelets, and nucleated hematopoietic cells Recently, the use of immunosuppressants tends to increase due to increase of autoimmune disease and organ transplantation patients. A large portion of leukemia and organ transplant patients developed VAHS as a secondary viral infection after anticancer drug and immunosuppressants therapy was administered In the field of ophthalmology, VAHS can occur by administration of immunosuppressants in corneal transplantation and autoimmune uveitis patients. Recently we experienced a case of fatal VAHS in a young uveitis patient who had been treated with immunosuppressants. We report this specfic case with literature review bec,lUse of the need for careful observation of general findings occurring during treatment of immunosuppressants such as corticosteroid.

PURPOSE: This study was performed to evaluate the changes in tear film and ocular surface after dacryocystorhinostomy (DCR) in patients with primary acquired nasolacrimal duct obstruction. METHODS: Forty subjects who showed successful results at three months after endoscopic DCR were investigated. The changes in tear breakup time (BUT), basal secretion test (BST), corneal sensitivity test (CST), tear clearance rate (TCR) and keratoepitheliopathy (KEP) were evaluated. RESULTS: The mean age was 57.4+/-13.2 years (29~77 years). Preoperative BST and BUT in eyes which underwent DCR were 13.21+/-3.79 mm and 8.20+/-2.30 seconds, respectively. Three months after the operation, the respective values were 9.13+/-3.77 mm (p=0.01) and 6.27+/-2.20 seconds (p=0.03). Preoperative CST, TCR and KEP in eyes which underwent DCR were 57.89+/-4.18 mm, 3.26+/-0.91 and 0.12+/-0.53, respectively. Three months after the operation, the respective values were 57.75+/-3.55 mm (p=0.32), 3.04+/-0.87 (p=0.08) and 0.13+/-0.54 (p=0.08). No changes were observed between the preoperative and postoperative tear parameters in fellow eyes. CONCLUSIONS: The changes in tear film parameters including BST and BUT should be considered in patients who receive endoscopic DCR.

The intramedullary nailing for humeral shaft fractures has become popular fixation method. It affords less invasive procedure, good stability and early rehabilitation. However many complications were reported such as nonunion, pain and motion limitation of shoulder. We managed 33 patients using interlocking intramedullary nail for the humeral shaft fractures, and nonunion occurred in 9 patients. We reviewed these 9 cases and analyzed the relationship between the nonunions and the fracture sites as well as fracture types. The results were as follows; 1. Nonunion occurred in 9 patients of 25 patients treated closed reduction, but did not occur in 8 patients treated open reduction. 2. The union was obtained in all 6 patients with proximal one third fracture. But nonunion occurred in 6 patients of 19 patients with middle one third fracture and in 3 patients of 8 patients with distal one third fracture. 3. Nonunion after interlocking nails for humeral shaft fractures did not occur in all 6 spiral fracture patients. Nonunion occurred in 5 patients of 8 comminuted fracture patients, in 3 patients of 6 transverse fracture patients and in 1 patient of 3 oblique fracture patients with below the middle one third of humerus. Our study showed that the high rate of nonunion occurred in the comminuted, transverse and oblique fracture below the middle one third of humerus. On the basis of these findings, we recommend that closer attention should be paid when choose the fixation method in these types of the humeral shaft fractures.

BACKGROUND: Androgenic alopecia (AGA) is the most common type of hair loss. It is likely inherited genetically and is promoted by dihydrotestosterone. 5α-reductase has been proven a good target through finasteride use. However, the pathogenesis of AGA cannot be fully explained based only on dihydrotestosterone levels. OBJECTIVE: To identify similar hairloss inhibition activity of RE-ORGA with mode of action other than finasteride. METHODS: We prepared RE-ORGA from Korean herb mixtures. We performed MTT assays for cytotoxicity, Cell Counting Kit-8 assays for cell proliferation, and western blot to identify expression levels of 5α-reductase and Bax. RNA-sequencing was performed for the expression patterns of genes in dihydrotestosterone-activated pathways. Anti-inflammatory activity was also assessed by the expression levels of tumor necrosis factor-alpha (TNF-α) and interleukin 6. RESULTS: REORGA could promote the proliferation of human dermal papilla cells and showed low cytotoxicity. It also inhibited the expression of 5α-reductases and Bax in the cells. RNA-sequencing results verified that the mRNA expressions of SRD5A1, Bax, transforming growth factor-beta 1 (TGF-β1), and TGF-β1 induced transcript 1 (TGFβ1I1) were decreased, whereas expression of protein tyrosine kinase 2 beta (PTK2β) was more elevated. REORGA also showed anti-inflammatory activity through decreased mRNA levels of TNF-α. CONCLUSION: Transcriptionally, up-regulation of PTK2β and concomitant down-regulation of TGFβ1I1 imply that RE-ORGA can modulate androgen receptor sensitivity, decreasing the expression of 5α-reductase type II and Bax together with TGF-β1 transcripts; RE-ORGA also showed partial anti-inflammatory activity. Overall, RE-ORGA is expected to alleviate hair loss by regulating 5α-reductase activity and the receptor's androgen sensitivity.

Objective:
Our goal was to review outcomes of patients with heterotopic pregnancies who under went surgical treatment.
Methods:
From January 1, 2005 to December 31, 2021, 27 women with heterotopic pregnancies who had undergone surgical treatment were enrolled. We investigated pregnancy outcomes based on clinical records and follow-up telephone interviews. Three of the 27 patients were excluded because we were unable to contact them.
Results:
Of the 24 patients included in the study, 17 underwent salpingectomies for tubal pregnan cies, 5 underwent wedge resections for cornual pregnancies, and 1 underwent a unilateral salpingooophorectomy for ovarian pregnancy. One patient with a suspected heterotopic cervical pregnancy had undergone extraction with forceps and curettage under abdominal ultrasound guidance. Three patients had spontaneous abortions after treatment for heterotopic pregnancies (2 tubal pregnancies, one cervical pregnancy). Twenty-one of 24 patients had heterotopic pregnancies that occurred after assisted reproductive technology. Three cases were heterotopic pregnancies that occurred without reproductive interventions. Among 24 patients who underwent surgical treatment, 18 patients (75.0%) had full-term deliveries.
Conclusion
There were no hospitalizations due to preterm labor, and 21 deliveries (87.5%) were either late preterm or full-term. There were no fetal abnormalities or maternal complications. Although the development of assisted reproductive technologies has increased the incidence of heterotopic pregnancy, the outcomes of heterotopic pregnancies are generally good.
