Background: Facial rejuvenation techniques using thread lifts are performed by passing sutures under the facial skin to treat sagging and facial flaccidity, and their advantages include a relatively short recovery time and relatively small incisions. In this study, we describe the short-term safety of a facial rejuvenation technique involving an absorbable polydioxanone monofilament thread (Mint Lift) in patients with mild-to-moderate facial skin sagging. Methods: The current multicenter, retrospective, case-series study was conducted in a total of 196 patients who visited the Grace Plastic Surgery Clinic or the Songdo IB Clinic between 2016 and 2018. The patients underwent insertion of the Mint Lift 43 and 17 in the deep temporal fascia and the deep subcutaneous layer, respectively. Of these patients, 179 met the eligibility criteria and their medical records were retrospectively reviewed. Results: The patients comprised six men (3.4%) and 173 women (96.6%), with a mean age of 44.4±14.4 years. In our series, postoperative complications included ecchymosis (1.7%), infection (0.4%), thread extrusion (1.1%), and skin dimpling (1.5%). No cases of iatrogenic nerve injury were observed, and all postoperative complications spontaneously resolved. Conclusions The Mint Lift 43 and 17 may be safe for thread lifting in patients with mildto-moderate facial skin sagging. However, further long-term follow-up studies are warranted.

BACKGROUND: The external jugular vein (EJV) is a useful intravenous (IV) cannulation site for anesthesiologists, although it has a relatively high failure rate. Unlike other central veins, visualization of the EJV is important during IV cannulation, and the Valsalva maneuver distends the jugular venous system. However, the relationship between the maneuver and EJV visibility remains unknown. This study compared EJV visibility before and after the Valsalva maneuver. METHODS: This was a prospective observational study that included 200 participants. After the induction of anesthesia, EJV visibility grade, depth from the skin to the EJV superficial surface (EJV depth), and EJV cross-sectional area (CSA) before the Valsalva maneuver were measured. The same parameters were measured after the Valsalva maneuver was performed. The EJV visibility grade was defined as grade A: good appearance and good palpation, grade B: poor appearance and good palpation, and grade C: poor appearance and poor palpation. RESULTS: Patient body mass index and EJV depth affected the EJV visibility grade before the Valsalva maneuver (p < 0.05), although EJV CSA did not. The Valsalva maneuver distended EJV CSA and reduced EJV depth, although these changes were not correlated with EJV visibility grade. With regard to EJV visibility, 34.0% of grade B cases and 20.0% of grade C cases were improved by the Valsalva maneuver. CONCLUSIONS: Although the Valsalva maneuver improved EJV CSA and EJV depth, it did not greatly affect EJV visibility grade.

Rectal burns caused by hot water enema have been reported only occasionally and the majority of them were treated in a conservative manner. Although intractable rectal stricture caused by rectal burn is rare, it may be treated by endoscopic intervention or surgery. A 52-year-old woman who had used various methods of enema to treat her chronic constipation eventually undertook a hot water enema herself. After that, anal pain and constipation became aggravated prompting her to visit our clinic. Although various nonoperative treatments including endoscopic stenting were performed, her obstructive symptom did not improve and endoscopic findings had not changed. Hence, we performed a laparoscopic proctosigmoidectomy and transanal coloanal anastomosis with ileal diversion to treat the disease, and as a result, her obstructive symptom improved well. Corrective surgery such as resection of involved segment with anastomosis may be beneficial in relieving obstructive symptoms of an intractable rectal stricture caused by hot water enema.

PURPOSE: We assessed the usefulness of magnetic resonance angiography(MRA) and its techniques for differential diagnosis of hemorrhagic causes in patients with non-traumatic intracranial hemorrhagic disease. MATERIALS AND METHODS: We retrospectively reviewed 74 patients with non-traumatic intracranial hemorrhagic diseases, which were confirmed by radiological examinations(36 cases) and operations(38 cases). We compared the usefulness of magnetic resonance imaging(MRI) alone from MRI with MRA in evaluation of hemorrhagic causes. MRA was obtained by Time-of-Flight(TOF) and Phase Contrast(PC) technique. We investigated the usefulness of TOF and PC technique. RESULTS: MRI with MRA for detection of hemorrhagic causes(89%, 66 cases) was better than MRI only (64%, 47 cases). PC was better than TOF for evaluation of arteriovenous malformation and aneurysm due to subtraction of background noise(hemorrhage). CONCLUSION: MRI with MRA in more useful than MRI alone for evaluation of non-traumatic intracranial hemorrhagic causes.

Background: Rapidly mutating (RM) Y-chromosomal short tandem repeats (Y-STRs) have been demonstrated to increase the possibility of distinguishing between male relatives due to a higher mutation rate than conventional Y-STRs. Massively parallel sequencing (MPS) can be useful for forensic DNA typing as it allows the detection of sequence variants of many forensic markers. Here, we present sequence variations of 31 Y-STRs including nine RM Y-STRs (DYF387S1, DYF399S1, DYF404S1, DYS449, DYS518, DYS570, DYS576, DYS612, and DYS627), their frequencies, distribution, and the gain in the number of alleles using MPS. Methods: We constructed a multiplex MPS assay capable of simultaneously amplifying 32 Y-chromosomal markers, producing amplicons ranging from 85–274 bp. Barcoded libraries from 220 unrelated males from four populations—African Americans, Caucasians, Hispanics, and Koreans—were generated via two-step polymerase chain reaction and sequenced on a MiSeq system. Genotype concordance between the capillary electrophoresis (CE) and MPS method and sequence variation of Y-STRs were investigated. Results: In total, 195 alleles were increased by MPS compared to CE-based alleles (261 to 456). The DYS518 marker showed the largest increase due to repeat region variation (a 3.69-fold increase). The highest increase in the number of alleles due to single nucleotide polymorphisms in the flanking region was found in DYF399S1. RM Y-STRs had more diverse sequences than conventional Y-STRs. Furthermore, null alleles were observed in DYS576 due to primer-binding site mutation, and allele drop-outs in DYS449 resulted from low marker coverage of less than the threshold. Conclusion The results suggest that the expanded and discriminative MPS assay could provide more genetic information for Y-STRs, especially for RM Y-STRs, and could advance male individualization. Compiling sequence-based Y-STR data for worldwide populations would facilitate the application of MPS in the field of forensic genetics and could be applicable in solving male-related forensic cases.

PURPOSE: The effect of PTK inhibitors (herbimycin A and genistein) on the induction of radiation-induce d apoptosis in Ph-positive K562 leukemia cell line was investigated. MATERIALS AND METHODS: K562 cells in exponential growth phase were irradiated with a linear accelerator at room temperature. For 6 MV X-ray irradiation and drug treatment, cultures were initiated at 2x10' cells/mL. The cells were irradiated with 10 Gy. Stock solutions of herbimycin A and genistein were prepared in dimethyl sulphoxide (DMSO). After incubation at 37C for 0-48 h, the extent of apoptosis was determined using agarose gel electrophoresis and TUNEL assay. The progression of cells throughth the cel l cycle after irradiation and drug treatment was also determined with flow cytometry. Western blot analysis was used to monitor bcl-2, bcl-X and bax protein levels. RESULTS: Treatment with 10 Gy X-irradiation did not result in the induction of apoptosis. The HMA alone (500 nM) also failed to induce apoptosis. By contrast, incubation of K562 cells with HMA after irradiation resulted in a substantial induction of nuclear condensation and fragmentation by agarose gel electro-phoresis and TUNEL assay. Genistein failed to enhance the ability of X-irradiation to induce DN A fragmentation. Enhancement of apoptosis by H MA was not attributable to downregulation of the bcl-2 or bcl-X anti-apoptotic proteins. When the cells were irradiated and maintained with HMA, the percentage cf cells in G2/M phase decreased to 30-40% at 48 h. On the other hand, cells exposed to 10 Gy X-irradiation alone or maintained with genistein did not show marked cell cycle redistribution. CONCLUSION: We have shown that nanomolar concentrations of the PTK inhibitor HMA synergize with X-irradiation in inducing the apoptosis in Ph (+) K562 leukemia cell line. While, genistein, a PTK inhibitor which is not selective for p2 10""'' failed to enhance the radiation induced apoptosis in K562 cells. It is unlikely that the ability of HMA to enhance apoptosis in K562 cells is attributable to bcl-2 family. It is plausible that the relationship between cell cycle delays and cell death is essential for drug development based on molecular targeting designed to modify radiation-induced apoptosis.

While anomalies of the pancreaticobiliary system are not uncommon, drainage of the common bile duct into the bulb of the duodenum has rarely been reported. The awareness of ectopic drainage of the CBD is stressed to prevent surgical damage and improve medical management in this area. We reported one case of anomalous drainage of the CBD and pancreatic duct associated with nonvisible gallbladder or agenesis of gallbladder and cystic duct diagnosed by ERCP, ultrasonography and upper abdominal CT.
