ABSTRACT

Background@#Proper nasal tip projection and rotation are essential for an aesthetically pleasing nose. However, East Asians usually have thicker skin and underdeveloped nasal cartilage compared to Caucasians. Thus, techniques such as the septal extension graft, columellar strut graft, and L-shaped alloplastic implants have been introduced for additional nasal tip support and projection. However, no consensus exists regarding the optimal method. @*Methods@#A hybrid columellar strut made of an osteochondral graft recombined with the nasal crest of the maxilla and conchal cartilage was devised. In a cadaveric study, changes due to an external bending force of the hybrid strut and costal cartilage in the same dimension were measured. In a comparative study, we divided 20 subjects into two groups according to the material used for the columellar strut graft: a hybrid columellar strut (experimental group) and a double-layered conchal columellar strut (control group). Preoperative, 1-month postoperative, and 1-year postoperative anthropometric measurements were compared between groups. @*Results@#In the cadaveric study, the hybrid columellar strut showed superior mechanical strength. In the comparative study, the average 1-year postoperative change of the columellar labial angle was significantly smaller in the experimental group (–0.7°±1.16° vs. 2.2°±1.32°, P=0.015). The hybrid columellar strut showed superior postoperative nasal tip stability. @*Conclusions@#We devised a new hybrid columellar strut and confirmed its superior mechanical firmness and stability. Considering the suggested indications and contraindications, the hybrid columellar strut graft can be a new modality for tip plasty in East Asian rhinoplasty that can provide sufficient long-term nasal tip stability.

ABSTRACT

Purpose@#Laparoscopic posterior retroperitoneal adrenalectomy (LPRA) is a surgical method that accesses the adrenal gland through the back. The aim of this study was to report initial experience of LPRA and evaluate possibilities for surgical application. @*Methods@#From March 2018 to December 2019, a total of 30 consecutive patients diagnosed with adrenal tumor underwent surgical treatment at Pusan National University Hospital were enrolled. Clinicopathologic features and various peri- and postoperative parameters were analyzed by retrospective medical record review. The mean age of the patients was 48.20 ± 13.66 years. @*Results@#The mean body mass index (BMI) was 25.50 ± 4.30 kg/m2 . Primary hyperaldosteronism was the most frequently preoperative diagnosed disease (n = 13, 43.4%), followed by adrenal incidentaloma (n = 8, 26.6%), Cushing syndrome (n = 5, 16.6%) and pheochromocytoma (n = 4, 13.3%). The mean size of postoperative adrenal tumor was 2.72 ± 1.76 cm. The mean operating time was 162 ± 58.14 minutes. Among the 30 patients, 28 patients underwent total adrenalectomy (93.3%) and two patients underwent cortical sparing adrenalectomy (6.7%). When LPRA was performed for patients with BMI > 23.16 kg/m2 , the operating time was longer than the average (P = 0.016). @*Conclusion@#LPRA was suitable and safe for patients with benign adrenal tumors. BMI, retroperitoneal fat density and postoperative adrenal weight may be related to the operating time, so they should be considered when deciding on a surgical method for adrenalectomy.

ABSTRACT

Purpose@#There are many studies on sentinel lymph node (SLN) biopsy in thyroid carcinoma but SLN biopsy (SLNB) in papillary thyroid carcinoma (PTC) remains open to debate. Therefore in this retrospective study, the usefulness of SLNB in thyroid carcinoma patients who had micro-PTC without cervical lymphadenopathy was assessed. @*Methods@#SLNB was performed in 114 patients who were diagnosed with micro-PTC in a single lobe without palpable or ultrasound-detected lymph node at the tertiary center between January 2012 and December 2013. After SLNB, all patients underwent total thyroidectomy and central neck dissection or thyroid lobectomy and central neck dissection of the single side. @*Results@#SLNs were identified in 112 of 114 patients with 41 positive SLNs and 71 negative SLNs on intraoperative frozen sections. However, eight negative patients were found to be positive in the final pathology. Sentinel node identification rate and false negative value of SLNB were 98.2% and 11.3%, respectively. In the univariate analysis, higher lymph node metastasis was detected in men than in women. Higher detection number of SLN showed higher probability of lymph node metastasis. @*Conclusion@#SLNB may be helpful in papillary thyroid cancer, especially in male patients. Also, it is useful for the staging of nodal status and clearance of persistent disease.

ABSTRACT

Purpose@#The purpose of this study was to compare the clinical characteristics and outcomes of hormone receptor-positive (HR+) human epidermal growth factor 2-negative (HER2–) breast cancer among elderly patients (over 65 years old) and younger patients. @*Methods@#This was a retrospective cohort study of 328 patients who were treated for breast cancer at Pusan National University Yangsan Hospital between January 2009 and December 2014. Tumor characteristics, surgical methods, and survival outcomes were compared between the two age groups (<65 and ≥65 years old). Kaplan-Meier curves for disease-free survival (DFS) and overall survival (OS) were also constructed according to the age groups. @*Results@#Among the 328 patients with HR+ HER2– breast cancer, 184 (56.1%) were <65 years old and 144 (43.9%) were ≥65 years old. Breast cancer stages were similar between the two age groups, but the older patients were treated less often with chemotherapy (81% vs. 66%, P=0.002). During the follow-up period, 17 deaths and 36 cases of recurrence or metastasis were reported. There was no difference in DFS between the two groups (P=0.840); however, the OS of the older age group was significantly lower than that of the younger age group (P=0.015). @*Conclusion@#This study suggested that HR+ HER2– breast cancer patients belonging to the two age groups had no significant difference in DFS. However, older age is an independent factor affecting OS rate. Therefore, even if patients are old, but their physical condition is satisfactory, standard and active treatment may be necessary, similar to that given to younger patients.

ABSTRACT

Synchronous quadruple colorectal cancer (CRC) is extremely rare without genetic alterations. We present a case of synchronous quadruple CRC with 2 lesions previously obscured by ischemic colitis. A 73-year-old woman was admitted to our emergency department. An abdominal computed tomography revealed ischemic colitis and irregular wall thickening of the sigmoid colon and sigmoid-descending junction, suspicious of 2 colon cancers. A colonoscopy examination revealed a fungating mass 20 cm from the anal verge, as well as ischemic colitis spanning the mucosa from the sigmoid colon to the transverse colon. The patient underwent laparoscopic Hartmann procedure. Pathologic examination confirmed both lesions as adenocarcinomas with microsatellite stable. Seven months postoperatively, instead of a laparoscopic Hartmann reversal, a laparoscopic total colectomy was performed due to the continued presence of severe ischemic colitis. The pathologic report suggested the presence of 2 distinct invasive adenocarcinomas in the descending colon without genetic alterations such as microsatellite instability.

ABSTRACT

Purpose@#Breast conserving surgery (BCS) is generally not considered for breast cancer because of concerns about the poor prognosis of triple negative breast cancer (TNBC). We assessed the outcomes of BCS and mastectomy for patients with stage II-IIIA TNBC. @*Methods@#The data of 172 breast cancer patients diagnosed with stage II-IIIA TNBC who underwent treatment at Pusan National University Hospital and Pusan National University Yangsan Hospital from 2010 to 2014 were retrospectively analyzed. The patients were divided into the following two groups: patients who underwent BCS (n=101) and those who underwent mastectomy (n=71). The Cox regression model was used to examine the outcomes of both treatments. The median follow-up period was 71 months in the BCS group, and 67 months in the mastectomy group. @*Results@#The median age of the 172 patients was 51 years (range, 22-82 years). In the BCS group, radiation therapy and chemotherapy (p<0.001 and p=0.007, respectively) were performed more frequently. The BCS group had more patients with a high Ki-67 index (p=0.006), while the mastectomy group included more patients with a higher pathologic T (pT) stage (p=0.005). The 5-year loco-regional recurrence-free, disease-free, and overall survival rates of the BCS group versus the mastectomy group were 93.8% versus 95.3%, 89.8% versus 90.7%, and 90.8% versus 86.3%, respectively, but the differences were not statistically significant. Lymphovascular invasion was a risk factor for disease-free survival and advanced stage was an important risk factor for overall survival. @*Conclusion@#In stage II-IIIA TNBC, BCS was not inferior to mastectomy in locoregional recurrence rates, disease-free survival rates, or overall survival rates.

ABSTRACT

Differentiated thyroid cancer (DTC) originating from thyroid tissue is affected by thyrotropin (TSH). TSH suppression therapy is usually recommended after thyroidectomy in cases of DTC. A 57-year-old woman who harbored a very huge recurred lymph node underwent TSH suppression therapy because of the risk of surgical complications. After TSH suppression, the huge neck lymph node exhibited a response and decreased in size. She had been followed up for 144 months. TSH suppression therapy could be considered as an alternative treatment option in a recurred DTC patient with a high perioperative risk.

ABSTRACT

Emphysematous gastritis is an infectious disease in which air is formed in the gastric wall by gas-forming organisms. It is infrequently reported but can be fatal without early diagnosis and treatment. The stomach is rarely infected because of the acidity of the gastric secretions and the rich blood supply. Treatment should be aimed at covering gram-negative organisms and anaerobes using broad-spectrum intravenous antibiotics, and occasional surgical management in order to enhance survival. Risk factors are those that lead to disrupted mucosal integrity, such as corrosive injury, and those that result in an immunosuppressed condition, including diabetes mellitus, chronic kidney disease, immunosuppressive drug use, and subsequent invasion by gas-forming organisms. We experienced a case of emphysematous gastritis that worsened after endoscopy. Aeration during upper endoscopy examination can cause barotrauma to the gastric wall with impairment of the mucosal barrier, resulting in the spread of gastric wall infection to the whole body. Therefore, we report this case and provide relevant literature review to suggest that early endoscopic evaluation can lead to exacerbation of emphysematous gastritis.

ABSTRACT

Decursin is a major biological active component of Angelica gigas Nakai and is known to induce apoptosis of metastatic prostatic cancer cells. Recently, other reports have been commissioned to examine the anticancer activities of this plant. In this study, we evaluated the inhibitory activity and related mechanism of action of decursin against glioblastoma cell line. Decursin demonstrated cytotoxic effects on U87 and C6 glioma cells in a dose-dependent manner but not in primary glial cells. Additionally, decursin increased apoptotic bodies and phosphorylated JNK and p38 in U87 cells. Decursin also down-regulated Bcl-2 as well as cell cycle dependent proteins, CDK-4 and cyclin D1. Furthermore, decursin-induced apoptosis was dependent on the caspase activation in U87 cells. Taken together, our data provide the evidence that decursin induces apoptosis in glioblastoma cells, making it a potential candidate as a chemotherapeutic drug against brain tumor.

ABSTRACT

PURPOSE: Deep vein thrombosis (DVT) is the third most common cause of cardiovascular morbidity and mortality. Anticoagulation has been the primary treatment modality for acute DVT. However, catheter-directed thrombolysis (CDT) has recently become widely accepted as an additional therapy to anticoagulation. We assessed comparative outcomes in patients with acute DVT who underwent anticoagulation therapy alone (ACA) group and those treated with CDT group. MATERIALS AND METHODS: We retrospectively reviewed medical records of 149 patients with DVT from January 2011 to December 2015. We compared patients who received ACA group (n=120) and those who received CDT plus anticoagulation (CDT group, n=29). We analyzed the prevalence of lesions, thrombus removal rate in each lesion, and recurrence-free rate between the two groups. RESULTS: We found thrombus involvement in a total of 281 lesions in the ACA group and 85 lesions in the CDT group. For the distribution of lesions in each group, those in the femoral vein accounted for 34.2% of all lesions and those in the popliteal vein accounted for 31.7%. During follow-up, the overall thrombus removal rate was 91.1% in the ACA group and 87.0% in the CDT group (P=0.273). The recurrence-free rate was higher in the CDT group in a log-rank test; however, there was no statistically significant difference between the two groups (P=0.594). CONCLUSION: According to our results, there was no significant difference in thrombus removal and recurrence-free rates between the CDT and ACA groups. ACA still has an important role in the treatment of DVT.

ABSTRACT

PURPOSE: Core needle biopsy (CNB) is a widely used procedure for breast cancer diagnosis and analyzing results of immunohistochemistry (IHC). Several studies have shown concordance or discordance in IHC results between CNB and surgical specimens (SS). A double-check (CNB and SS) is inefficient and costly to perform a double-check on all patients. Therefore, it is important to determine which patients would benefit from a double-check. METHODS: We collected the medical records of patients who underwent breast cancer surgery at Pusan National University Yangsan Hospital between April 2009 and June 2018 (n = 620). Molecular subtypes were classified as follows by hormone receptors (HR) and human epidermal growth factor receptor-2 (HER2): HR+/HER2+, HR+/HER2−, HR−/HER2+, HR−/HER2−. Clinicopathological factors including age, obesity, histological grade, preoperative CEA, CA15-3, T stage, N stage, and menopausal status were assessed to determine whether they were associated with subtype change. RESULTS: Increasing histological grade (P < 0.001; odds ratio [OR], 3.693; 95% confidence interval [CI], 1.941–7.025), preoperative CEA ≥ 5 ng/mL (P =0.042; OR, 2.399; 95% CI, 1.009–5.707) and higher T stage (P = 0.015; OR, 2.241; 95% CI, 1.152–4.357) were significantly associated with subtype change. On multivariable analyses, subtype changes were more common in high-grade breast cancer (P < 0.001; OR, 1.077; 95% CI, 1.031–1.113) and CEA ≥ 5 (P = 0.032; OR, 2.658; 95% CI, 1.088–6.490). CONCLUSION: Patients with moderate- to high-grade tumors or CEA ≥ 5 ng/mL are required a double-check to determine the molecular subtype of breast cancer.

ABSTRACT

Gastric tuberculosis accounts for approximately 2% of all cases of gastrointestinal tuberculosis. Diagnosis of gastric tuberculosis is challenging because it can present with various clinical, endoscopic, and radiologic features. Tuberculosis manifesting as a gastric subepithelial tumor is exceedingly rare; only several dozen cases have been reported. A 30-year-old male visited emergency room of our hospital with hematemesis and melena. Abdominal CT revealed a 2.5 cm mass in the gastric antrum, and endoscopy revealed a subepithelial mass with a visible vessel at its center on gastric antrum. Primary gastric tuberculosis was diagnosed by surgical wedge resection. We report a rare case of gastric tuberculosis mimicking a subepithelial tumor with acute gastric ulcer bleeding.

ABSTRACT

OBJECTIVE: This study examined patients who visited the emergency department of a national medical center equipped with rabies vaccine and rabies immunoglobulin to confirm whether the treatment for rabies vaccination was appropriate in the emergency department. METHODS: This was a retrospective study that included 397 patients from January 1, 2014, to October 31, 2017. The patients finally diagnosed with animal bites according to the International Classification of Diseases, 10th revision code, at emergency department were collected. RESULTS: Most of the patients were 20–30 years old. Most of them were bitten by a dog, especially in the upper limb. Only 84% of patients who met the domestic rabies post-exposure prophylaxis (PEP) criteria were vaccinated. Patients who did not meet the criteria, approximately 22.3%, were also vaccinated. Complications after vaccination included clinical symptoms, such as headache, numbness, mild itching, and heating sensation. CONCLUSION: Rabies is a disease that can be prevented through PEP. Rabies PEP is relatively expensive and difficult to vaccinate easily, so it is desirable to subdivide the existing domestic rabies PEP guidelines into reality. Emergency physicians should know the proper rabies vaccination criteria and vaccinate patients only if necessary. This will help reduce medical resources and the complications of rabies vaccinations.

ABSTRACT

Mycotic aneurysms of the common carotid artery (CCA) are very rare and warrant surgical treatment to prevent rupture and death. A 89-year-old man who complained of a sore throat and swelling of the right side of neck. He had no history of trauma or neck infection. Physical examination revealed hard and pulsatile mass. Computed tomography showed initially pseudoaneurysm rupture on the right CCA with surrounding inflammation. The emergency operation revealed mycotic aneurysm rupture with CCA necrosis and was successfully done by wide debridement and carotid artery resection with interposition bypass. The resected tissue and blood culture grew growth of Staphylococcus aureus group. We report a rare case of mycotic aneurysm of right CCA that treated by bypass interposition.

ABSTRACT

Gitelman syndrome is characterized by hypokalemia, metabolic alkalosis, hypocalciuria, and hypomagnesemia. The clinical course of Gitelman syndrome in pregnant women remains unclear, but it is thought to be benign. We report here the first Korean case of atypical eclampsia in a 31-year-old who was diagnosed with Gitelman syndrome incidentally during an antenatal screening test. The patient did well during pregnancy despite significant hypokalemia. At 33 weeks’ gestation, the patient exhibited eclampsia, hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome, and renal insufficiency without significant hypertension or proteinuria. We explain this unusual clinical course through a review of the relevant literature.

ABSTRACT

BACKGROUND: Keratinocytes are the major cells in epidermis, providing barrier components such as cornified cells through the sophisticated differentiation process. In addition, keratinocytes exerts their role as the defense cells via activation of innate immunity. It has been known that pathogen-associated molecular patterns (PAMPs) including double-strand RNA and nucleotides can provoke inflammatory reaction in keratinocytes. OBJECTIVE: The aim of this study is to evaluate the effect of Ampelopsis japonica Makino extract (AE) on PAMPs-induced inflammatory reaction of keratinocytes. METHODS: The effects of AE were determined using poly (I:C)-induced inflammation and imiquimod-induced psoriasiform dermatitis models. RESULTS: In cultured keratinocytes, AE significantly inhibited poly(I:C)-induced expression of inflammatory cytokines, such as interleukin (IL)-1β, IL-6, IL-8 and tumor necrosis factor-α. AE significantly inhibited poly(I:C)-induced release of caspase-1 active form (p20), and down-regulated nuclear factor-κB signaling pathway. In imiquimod-induced psoriasiform dermatitis model, topical application of AE resulted in significant reduction of epidermal hyperplasia. CONCLUSION: These results suggest that AE may be a potential candidate for the treatment of skin inflammation.

ABSTRACT

Prostatic abscess is not a common entity which is characterized by non-specific clinical presentations. This poses a diagnostic challenge for clinicians. Clinicians routinely consider antibiotic treatments concomitantly with drainage for the treatment of prostatic abscess. But there are no established guidelines for its optimal timing, methods and indications. Surgical drainage procedures include transurethral resection of the prostate and perineal incision and drainage. But there is variability in the prognosis of patients between the procedures. We have treated a 48-year-old diabetes patient with prostatic abscess accompanied by MRSA bacteremia using a percutaneous fine-needle aspiration under the computed tomography (CT) guidance. The patient achieved improvement of the symptoms and in follow up CT findings. A percutaneous drainage under the CT guidance is advantageous in that it causes fewer complications. However, Further studies are warranted to establish the optimal timing, methods and indications in patients with prostate abscess.
