Background and Objectives: Laryngopharyngeal reflux (LPR) is an increasingly common disease, characterized by stomach acid reflux reaching the upper airways. Postnasal drip (PND) is a known consequence of LPR, defined as mucus accumulation perceived in the posterior areas of the nose and throat. PND is among the most common causes of persistent cough, hoarseness, sore throat, and other symptoms, affecting the quality of life. This study aimed to evaluate the effects of a proton-pump inhibitor (PPI) on PND symptoms in patients with LPR. Methods: We prospectively enrolled patients diagnosed with LPR at our institution between September 2019 and June 2020. The patients were randomly assigned to either the treatment group (20 mg of ilaprazole daily for 8 weeks) or the control group. The scores for the Reflux Symptom Index (RSI), Reflux Finding Score (RFS), and Sino-Nasal Outcome Test (SNOT)-20 were evaluated at baseline and at the end of treatment, focusing on PND symptoms. Results: Eighty patients (28 men and 52 women; mean age, 48.8 years, range, 22–78 years) were enrolled, with 43 in the treatment group and 37 in the control group. The initial RSI, RFS, and SNOT-20 scores were similar between the two groups, and they decreased significantly only in the treatment group (p=0.002, p<0.001, and p=0.015, respectively). However, the PND symptom scores showed a significant decrease in the treatment group only in the RSI (p=0.012). Conclusion PPI treatment for 8 weeks may be effective in improving PND symptoms in patients with LPR.

Purpose: Robotic head and neck surgery is widespread nowadays. However, in the reconstruction field, the use of robotic operations is not. This article aimed to examine methodologies for conventional head and neck reconstruction after robotic tumor surgery in an effort to obtain further options for future reconstruction manipulations. Materials and Methods: A retrospective review of all patients who received head and neck robot surgery and conventional reconstructive surgery between October 2016 and September 2021. Results: In total, 53 cases were performed. 67.9% of the tumors were greater than 4 cm. Regarding defect size, 47.2% of the lesions were greater than 8 cm. In terms of TNM stage, stage 3 disease was recorded in 26.4% and stage 4 in 52.8%. To make a deep and narrow field wider, we changed the patient’s posture in pre-op field, additional dissection was done. We used radial forearm flap mostly (62.2%). Conclusion Conventional head and neck reconstruction after robotic ENT cancer surgery is possible. One key step is to secure additional space in the deep and narrow space left after robotic surgery. For this, we opted for a radial forearm flap mostly. This can be performed as a bridgehead to perform robotic head and neck reconstruction.

Background: Psoriasis is a chronic disease that can have accompanying comorbidities including arthritis, metabolic syndrome, and cardiovascular diseases. Patients with psoriasis tend to frequently visit medical institutions, and their economic burden for medical services is high. Objective: To investigate the economic burden of psoriasis in Korea. Methods: The Korean Society for Psoriasis conducted a multi-center field survey of the patients and analyzed the national insurance claim data. Also, we discussed the medical environment of psoriasis in Korea based on the results. Results: The economic burden of psoriasis patients is substantial and varied by the type of medical institute. Patients also paid the indirect and intangible medical costs. Biological agents, which is used in patients with severe psoriasis, led to an increase in the cost. Conclusion This is the first study to estimate the economic burden of psoriasis in Korea comprehensively. To improve the medical environment of psoriasis and alleviate the burden of patients, discussion on the more efficient health policy and medical insurance criteria for psoriasis would be needed.

Although the success rate of deep inferior epigastric perforator (DIEP) flaps has increased, late flap failures still occur and have a low salvage rate. The present article describes a case of salvage of a case of late flap failure using the pedicle vein as a vein graft source. A 50-year-old woman underwent a bilateral DIEP free flap procedure. On postoperative day 6, she experienced flap compromise and underwent emergency flap revision. In the flap revision, flap venous drainage and the superficial inferior epigastric vein were completely obstructed. A Fogarty catheter was used to remove a thrombus from the completely obstructed pedicle vein, and this pedicle vein was used as a graft source and was ligated in retrograde fashion to the flap vein stump. After injection of urokinase into the arterial branch, venous flow to the flap was restored. At a 6-month follow-up visit in the outpatient clinic, only partial fat necrosis at the flap was noted. By dissecting various perforators in the initial operation, decisions regarding immediate revision can be made with more confidence. Additionally, the combined procedures performed in this case may be helpful even for practitioners treating cases of late flap compromise.

BACKGROUND: Although previous studies have focused on determining prognostic and causative variables associated with fistula-related complications after head and neck reconstructive surgery, only a few studies have addressed preventive measures. Noting that pooled saliva complicates wound healing and precipitates fistula-related complications, we devised a continuous suction system to remove saliva during early postoperative recovery. METHODS: A continuous suction system was implemented in 20 patients after head and neck reconstructive surgery between January 2012 and October 2017. This group was compared to a control group of 16 patients at the same institution. The system was placed orally when the lesion was on the anterior side of the retromolar trigone area, and when glossectomy or resection of the mouth floor was performed. When the orohypopharynx and/or larynx were eradicated, the irrigation system was placed in the pharyngeal area. RESULTS: The mean follow-up period was 9.2±2.4 months. The Hemovac system was applied for an average of 7.5 days. On average, 6.5 days were needed for the net drain output to fall below 10 mL. Complications were analyzed according to their causes and rates. A fistula occurred in two cases in the suction group. Compared to the control group, a significant difference was noted in the surgical site infection rate (P < 0.031). CONCLUSIONS: Clinical observations showed reduced saliva pooling and a reduction in the infection rate. This resulted in improved wound healing through the application of a continuous suction system.

PURPOSE: Reactive oxygen species modulator 1 (Romo1) is a key mediator of intracellular reactive oxygen species production. However, examination of the clinical usefulness of Romo1 in cancers has been limited. We evaluated the association of Romo1 expression with clinical outcomes in advanced non-small cell lung cancer (NSCLC) patients treated with platinum-based chemotherapy. MATERIALS AND METHODS: Romo1 expression in tumor tissue was examined by immunohistochemistry and evaluated by histological score. Survival analyses were performed according to Romo1 expression and the association between Romo1 expression and clinical parameters was evaluated. RESULTS: A total of 88 tumor specimens were analyzed. Significantly shorter median progression-free survival (PFS) was observed in the high Romo1 group compared with the low Romo1 group (4.5 months vs. 9.8 months, p < 0.001), and the median overall survival (OS) of the high Romo1 group was also significantly shorter than that of the low Romo1 group (8.4 months vs. 15.5 months, p < 0.001). Results of multivariate analyses showed significant association of high Romo1 expression with both poor PFS (hazard ratio [HR], 2.75; 95% confidence interval [CI], 1.71 to 4.44) and poor OS (HR, 3.99; 95% CI, 2.36 to 6.74). Results of the subgroup analysis showed a similar association regardless of tumor histology. Romo1 expression showed no association with any clinical parameter including age, sex, smoking status, stage, differentiation, or tumor histology. CONCLUSION: Romo1 overexpression was associated with poor response to treatment and shorter survival in advanced NSCLC patients treated with platinum-based chemotherapy. Romo1 could be a potential adverse predictive marker in this setting.

BACKGROUND: Reconstruction of oropharyngeal defects after resection of oropharyngeal cancer is a significant challenge. The purpose of this study is to introduce reconstruction using a combination of a buccinator myomucosal flap and a buccal fat pad flap after cancer excision and to discuss the associated anatomy, surgical procedure, and clinical applications. METHODS: In our study, a combination of a buccinator myomucosal flap with a buccal fat pad flap was utilized for reconstruction after resection of oropharyngeal cancer, performed between 2013 and 2015. After oropharyngectomy, the defect with exposed vital structures was noted. A buccinator myomucosal flap was designed and elevated after an assessment of the flap pedicle. Without requiring an additional procedure, a buccal fat pad flap was easily harvested in the same field and gently pulled to obtain sufficient volume. The flaps were rotated and covered the defect. In addition, using cadaver dissections, we investigated the feasibility of transposing the flaps into the lateral oropharyngeal defect. RESULTS: The reconstruction was performed in patients with squamous cell carcinoma. The largest tumor size was 5 cm x 2 cm (length x width). All donor sites were closed primarily. The flaps were completely epithelialized after four weeks, and the patients were followed up for at least six months. There were no flap failures or postoperative wound complications. All patients were without dietary restrictions, and no patient had problems related to mouth opening, swallowing, or speech. CONCLUSIONS: A buccinator myomucosal flap with a buccal fat pad flap is a reliable and valuable option in the reconstruction of oropharyngeal defects after cancer resection for maintaining functionality.

BACKGROUND: Nitrous oxide (N2O) and remifentanil both have anesthetic-reducing and antinociceptive effects. We aimed to determine the anesthetic requirements and stress hormone responses in spinal cord-injured (SCI) patients undergoing surgery under sevoflurane anesthesia with or without pharmacodynamically equivalent doses of N2O or remifentanil. METHODS: Forty-five chronic, complete SCI patients undergoing surgery below the level of injury were randomly allocated to receive sevoflurane alone (control, n = 15), or in combination with 67% N2O (n = 15) or target-controlled infusion of 1.37 ng/ml remifentanil (n = 15). Sevoflurane concentrations were titrated to maintain a Bispectral Index (BIS) value between 40 and 50. Measurements included end-tidal sevoflurane concentrations, mean arterial blood pressure (MAP), heart rate (HR), and plasma catecholamine and cortisol concentrations. RESULTS: During surgery, MAP, HR, and BIS did not differ among the groups. Sevoflurane concentrations were lower in the N2O group (0.94 +/- 0.30%) and the remifentanil group (1.06 +/- 0.29%) than in the control group (1.55 +/- 0.34%) (P < 0.001, both). Plasma concentrations of norepinephrine remained unchanged compared to baseline values in each group, with no significant differences among groups throughout the study. Cortisol levels decreased during surgery as compared to baseline values, and returned to levels higher than baseline at 1 h after surgery (P < 0.05) without inter-group differences. CONCLUSIONS: Remifentanil (1.37 ng/ml) and N2O (67%) reduced the sevoflurane requirements similarly by 31-39%, with no significant differences in hemodynamic and neuroendocrine responses. Either remifentanil or N2O can be used as an anesthetic adjuvant during sevoflurane anesthesia in SCI patients undergoing surgery below the level of injury.

A rectal cancer was found in a 67-year-old man with a history of neurofibromatosis type 1. A low anterior resection was performed, and he received concurrent chemoradiation for 6 months. Twelve months after the surgery, a tumor was found at the anastomotic site by positron emission tomography-computed tomography and colonoscopy and was mistaken as anastomotic site recurrence. The tumor was confirmed as an inflammatory myofibroblastic tumor through transanal excision.
