BACKGROUND: This study evaluated dynamic changes in eyebrow position related to aging. METHODS: Female participants were recruited and separated into two groups aged 20–30 years (the younger group, n=20; mean age, 24.8 years) and 50–70 years (the older group, n=20; mean age, 55.8 years). Photogrammetry was used to determine the eyebrow position at the medial canthus (MC), lateral limbus, lateral canthus, and lateral end point (EP) for 6 actions: smooth opening (the reference action) and closing of the eye, forward gaze, maximum opening and closing of the eye, and maximum frown. Videos were also recorded. RESULTS: No differences in eyebrow position were detected at the MC when opening or closing the eyes smoothly, gazing straight ahead, or closing the eyes maximally. For all 6 actions, the position of the lateral EP in the older group was significantly lower than in the younger group (P=0.003), and the smallest degree of vertical movement at this point was found in both age groups (P<0.001). Vertical movement at the 4 landmarks of the eyebrows decreased with aging. CONCLUSIONS: Eyebrow position was unchanged at the MC with aging, except at maximal eye opening and maximal frown. No differences in eyebrow position were observed between the younger and older groups when eyes were maximally closed, except at the EP. It is important to focus on correction of the lateral EP for periorbital rejuvenation.

PURPOSE: The cephalic index (CI) is used to classify the head and every race has its unique characteristics. Previous studies published in Korea were limited to demonstrating the periodical change of the CI. This study was done to determine the CI change in 0 to 20 year-old Koreans by sex and age. METHODS: The measurement was done on 1,222 Koreans ranging from 0 to 20 years of age, randomly selected from 2,156 who were diagnosed with simple concussion, had no other diseases or anomalies, and took cephalographs from January, 2000 to July, 2008. The files were obtained from Marosis(R) and then photogrammetry was done by Photoshop(R). To standardize the cephalograph, the Frankfort horizontal line was selected as the reference line on lateral view and the line connecting both lateral-orbitales on AP view. The maximal length was obtained from the lateral cephalograph and the maximal breadth from the AP cephalograph. RESULTS: The CI showed no difference by sex (p=0.4848). The CI and age showed negative correlation (p<0.0001). Analyzed separately by the male and the female, the CI showed statistical significance in the male (p<0.0001), but not in the female (p=0.4741) group. Comparing the CI above the age of 11, the CI of the female became greater than that of the male. CONCLUSION: This study contributes to the standardization of CI measurement and the authors were able to obtain the average CI by age. We concluded that the CI decreased according to age and most Koreans belonged to barchycephalic or hyperbrachycephalic.

PURPOSE: To correct the upper lip depression after the correction of unilateral cleft lip, autologous grafts such as bone, dermal, fascial grafts and fat injections or alloplastic implants are used. Transplanted bones, dermis and fascia have a tendency to be absorbed and have donor morbidity. Fat injections are absorbed inconsistently and alloplastic implants have problems such as foreign body reactions, protrusions and infections. Authors corrected the upper lip depression using conchal cartilage graft in unilateral cleft lip deformity and the results was analysed with photos. METHODS: 26-unilateral cleft lip and 2-microform cleft lip cases, totally 28 cases were performed. Their mean age was 21.89 years. The male and female cases were 12 and 16, respectivley. Under anesthesia (general: 18 cases and local: 10 cases), cavum conchae (n=8), cymba conchae (n=16) and whole conchae (n=4) were harvested. Transversely cut the margin of the obtained cartilage, we cut out the most bent portion and put a partial-thickness incision on concave surface in cases of excessive convexity. Then, we performed the onlay graft of the conchal cartilage via scar revision site in unilateral cleft lip and via the reconstruction site of the cupid bow in microform cleft lip. The augmentation of the upper lip was evaluated with photos. Adapting the baseline connecting between the both cheilions as a horizontal standard line, we measured the highest point among the tangents between the upper lip and nose (point a), the lowest point (point c), the middle point between a and c (point b) and the vertical line from the alare (point d) to the horizontal standard line. To assess the postoperative symmetry, we compared cleft side upper lip contour index (%) A,B,C,D=(a,b,c,d)-ch x 100/(ch-ch) and non-cleft side upper lip contour index (%) A',B',C',D'= (a',b',c',d')-ch x 100 / (ch-ch).h) RESULTS: After the surgery, no complication was found except in one case which double layers graft performed in the cleft lip deformity, the lateral portion was protruded. The upper lip contour index, the difference of A and A' were-0.83%, and thus the mild depression was persisted. Difference of B and B', C and C', D and D' were 0.83%, 1.07%, 0.90%. There were statistically significant difference, and thus the depression of upper lip were improved generally. CONCLUSION: Authors performed the onlay graft of the conchal cartilage in unilateral cleft lip deformity and found that the depression of the upper lip was well corrected except the uppermost part when photogrammetrically analyzed.

BACKGROUND: Among the various methods for correcting nasal deformity, the composite graft is suitable for the inner and outer reconstruction of the nose in a single stage. In this article, we present our technique for reconstructing the ala and columella using the auricular chondrocutaneous composite graft. METHODS: From 2004 to 2011, 15 cases of alar and 2 cases of columellar reconstruction employing the chondrocutaneous composite graft were studied, all followed up for 3 to 24 months (average, 13.5 months). All of the patients were reviewed retrospectively for the demographics, graft size, selection of the donor site and outcomes including morbidity and complications. RESULTS: The reasons for the deformity were burn scar (n=7), traumatic scar (n=4), smallpox scar (n=4), basal cell carcinoma defect (n=1), and scar contracture (n=1) from implant induced infection. In 5 cases of nostril stricture and 6 cases of alar defect and notching, composite grafts from the helix were used (8.9x12.5 mm). In 4 cases of retracted ala, grafts from the posterior surface of the concha were matched (5x15 mm). For the reconstruction of the columella, we harvested the graft from the posterior scapha (9x13.5 mm). Except one case with partial necrosis and delayed healing due to smoking, the grafts were successful in all of the cases and there was no deformity of the donor site. CONCLUSIONS: An alar and columellar defect can be reconstructed successfully with a relatively large composite graft without donor site morbidity. The selection of the donor site should be individualized according to the 3-dimensional configuration of the defect.

Vertebral osteomyelitis is primarily seen in middle-aged individuals, with a mean age of presentation of ~60 years. Recent trends suggest an increase in the incidence of vertebral osteomyelitis due to longer life expectancy of patients with chronic debilitating diseases. Haemophilus influenzae is a small, fastidious, gram-negative bacillus, which is known to cause infections in young children. While invasive H. influenzae infections have become increasingly common in adult populations, bone infections caused by this organism remain extremely rare. The existing medical literature includes only 11 reports of vertebral osteomyelitis caused by H. influenzae since 1978, with no reports of H. influenzae-associated vertebral osteomyelitis observed in Korea. Here, we present the case of a 72-year old patient with hematogenous vertebral osteomyelitis and psoas abscess caused by non-typeable H. influenzae.

The therapeutic effects of the leaves of Couroupita guianensis, a large tropical tree in the family of Lecythidaceae improving testosterone-induced Benign Prostatic Hyperplasia (BPH) were tested In Vitro and In Vivo. In BPH rats induced by castration and testosterone treatment, the prostate index was improved in groups administered with the extracts of C. guianensis extracted with 50%-, 100%-ethanol or boiling water, which was comparable with positive control, finasteride. The extract C. guianensis leaves showed significant inhibition on the expressions of type 2 5-alpha reductase (5αR) in RWPE-1 human prostatic epithelial cells, and effectively attenuated the expressions of androgen receptor, type 2 5αR and proliferating cell nuclear antigen in LNCap human prostatic adenocarcinoma cells. The leaves of C. guianensis that exerted evident suppression on BPHrelated biomarkers In Vitro and improvement of prostate index In Vivo has a potential therapeutic use for the treatment of BPH.

Purpose: This study aims to investigate the feasibility of Zenith Fenestrated AAA Endovascular Graft (Z-FEN, Cook Medical) from a single Korean institution database by evaluating the vascular anatomy of Korean abdominal aortic aneurysm (AAA) patients with hostile aortic neck. Methods: This is a retrospective study on patients with AAA who underwent endovascular aortic repair (EVAR) and open surgery repair between January 2012 and December 2021 (n = 211). The anatomic characteristics of the aortic neck were evaluated using 3-dimensional reconstructed computed tomographic scans. For the juxtarenal AAA patients (n = 39), feasibility of fenestrated stent graft was evaluated under the protocol of fenestrated EVAR. For those who were not suitable for the application of Z-FEN, the reasons for unsuitability were analyzed. Results: Among 211 AAA patients, 108 patients (51.2%) had complex aortic neck, and 39 (18.5%) had insufficient aortic neck length (<15 mm) for conventional EVAR. Of the 39 patients with juxtarenal AAAs, 13 (33.3%) were determined feasible for Z-FEN. Twenty-six patients (66.7%) were noncandidate for Z-FEN due to severe neck angulation, short aortic neck length, inadequate iliac artery anatomy, large aortic neck diameter, and severe calcification and thrombosis. Proximal aortic neck length of the non-feasible group was significantly shorter than that of the feasible group (P = 0.002). Conclusion Z-FEN was applicable to 33.3% of the juxtarenal AAA patients. As recent studies confirm, the effectiveness and safety of fenestrated EVAR, Z-FEN can be an option for AAA patients with short aortic neck.

Objective: Striatal dopamine dysfunction caused by cortical abnormalities is a leading hypothesis of schizophrenia. Although prefrontal cortical pathology is negatively correlated with striatal dopamine synthesis, the relationship between structural frontostriatal connectivity and striatal dopamine synthesis has not been proved in patients with schizophrenia with different treatment response. We therefore investigated the relationship between frontostriatal connectivity and striatal dopamine synthesis in treatment-responsive schizophrenia (non-TRS) and compared them to treatment-resistant schizophrenia (TRS) and healthy controls (HC). Methods: Twenty-four patients with schizophrenia and twelve HC underwent [18F] DOPA PET scans to measure dopamine synthesis capacity (the influx rate constant Kicer) and diffusion 3T MRI to measure structural connectivity (fractional anisotropy, FA). Connectivity was assessed in 2 major frontostriatal tracts. Associations between Kicer and FA in each group were evaluated using Spearman’s rho correlation coefficients. Results: Non-TRS showed a negative correlation (r=-0.629, p=0.028) between connectivity of dorsolateral prefrontal cortex-associative striatum (DLPFC-AST) and dopamine synthesis capacity of associative striatum but this was not evident in TRS (r=-0.07, p=0.829) and HC (r=-0.277, p=0.384). Conclusion Our findings are consistent with the hypothesis of dysregulation of the striatal dopaminergic system being related to prefrontal cortex pathology localized to connectivity of DLPFC-AST in non-TRS, and also extend the hypothesis to suggest that different mechanisms underlie the pathophysiology of non-TRS and TRS.

Scrub typhus develops after the individual is bitten by a trombiculid mite infected with Orientia tsutsugamushi. Since it has been reported that pneumonia is frequently observed in patients with scrub typhus, we investigated whether intranasal (i.n.) vaccination with the outer membrane protein of O. tsutsugamushi (OMPOT) would induce a protective immunity against O. tsutsugamushi infection. It was particular interest that when mice were infected with O. tsutsugamushi, the bacteria disseminated into the lungs, causing pneumonia. The i.n. vaccination with OMPOT induced IgG responses in serum and bronchoalveolar lavage (BAL) fluid. The anti-O. tsutsugamushi IgA Abs in BAL fluid after the vaccination showed a high correlation of the protection against O. tsutsugamushi. The vaccination induced strong Ag-specific Th1 and Th17 responses in the both spleen and lungs. In conclusion, the current study demonstrated that i.n. vaccination with OMPOT elicited protective immunity against scrub typhus in mouse with O. tsutsugamushi infection causing subsequent pneumonia.
