Dietary behavior and its influencing factors among experienced shiftwork nurses: a secondary analysis.

PURPOSE: This study investigated the dietary behavior of experienced shiftwork nurses and aimed to identify factors related to dietary behavior. METHODS: This study was a secondary analysis based on the Shift Work Nurses' Health and Turnover study (2018-2021) among Korean nurses. In total, 247 experienced (>12 months) shiftwork nurses were included in this study. The participants' dietary behavior, depression, level of occupational stress, fatigue, physical activity, and general characteristics were measured. Descriptive statistics, Pearson correlation coefficients, independent t-test, one-way analysis of variance, the Kruskal-Wallis test, and multiple regression analysis were conducted. RESULTS: The dietary behavior score of the participants using the Mini-Dietary Assessment Index was 29.35±5.67. Thirty percent of the participants were depressed, the participants experienced moderate occupational stress, and 74.1% of the participants engaged in an inadequate amount of physical activity. The factors influencing shiftwork nurses' dietary behavior were having child(ren) (ß=.16, p=.027), depression (ß=-.13, p=.032), level of occupational stress related to occupational climate (ß=-.13, p=.035), and an inadequate amount of physical activity (ß=-.17, p=.006). These factors explained 10.4% of the variance in experienced shiftwork nurses' dietary behavior scores. CONCLUSION: Experienced nurses with child(ren) tended to have healthier diets. However, a higher level of occupational stress related to occupational climate, depression, and engaging in an inadequate amount of physical activity were associated with a higher risk of having an unhealthy diet. Therefore, strategies are needed to encourage physical activity and alleviate adverse occupational climate and depression among experienced nurses.

Understanding Nasal Valve Compromise in Nasal Airway Obstruction: A New Classification System.

OBJECTIVES: A key aspect of rhinoplasty is integrity of nasal valves area because of its fundamental role in patent nasal airway. furthermore, nasal obstruction is a dominant feature in patient with nasal valves dysfunction (NVD) which can be devastating outcome after rhinoplasty. METHODS: Nonetheless, NVD has been widely investigated regarding their etiologies and management. However, it has been assumed that the anatomical complexity and interplay between its structures causing a confusion for a beginner surgeon to diagnose and treat NVD. This study was approved by the institutional review board of Chosun University Hospital, Gwangju, Korea (2022-11-005). RESULTS: To date, the lack of consensus on nasal valve pathologies and corrective procedures has led to its underestimations during analysis and management. As result, we proposed a classification system based on its affected anatomical part, location, and their management. Thus, implementing a classification system for NVD will help guide the practice of rhinoplasty and introduce a more structured approach. CONCLUSION: This approach will prove useful in expanding our understanding of how important to locate the pathology of NVD and apply the most relevant management options, particularly for a beginner surgeons.

Dynamic evaluation of facial muscles: 3D skin displacement vector analysis using a facial painting model.

BACKGROUND: Botulinum toxin A can be used to eliminate dynamic wrinkles by relaxing the muscles involved in facial expressions. Therefore, it is essential to know the location, origin, insertion, function, and changes of the facial expression muscles according to their contraction. METHODS: After drawing the muscles on the face of a model, pictures were taken at rest. The model was then asked to make facial expressions that cause facial wrinkles. All images were taken with the Vectra H1 camera system (Canfield Scientific, Inc., Fairfield, New Jersey). Each expression image was aligned to its respective static image to compute the differences in skin position, so as to calculate the skin displacement vectors. The values for local changes in skin displacement were calculated by applying the automated algorithms of the Vectra Software Mirror Suite and visualized using the color and size of the arrow. RESULTS: Face painting and 3D skin vector displacement analyses enabled visualization of all the facial muscles involved in facial expressions working dynamically, allowing us to visualize the effect of each muscle in the creation of hyperkinetic wrinkles. Face painting and 3D skin vector displacement analyses can be combined to determine the location of the wrinkles, extent of the muscle, part of the muscle that contracts, presence of asymmetry, direction in which the muscle contracts, and correlation between the antagonists and synergistic muscles. CONCLUSION: The botulinum toxin A injection educational model using body painting and 3D skin vector displacement analyses can provide a deeper understanding of actual moving muscle anatomy.

Complications of Alloplast Rhinoplasty and Their Management: A Comprehensive Review.

In Asian countries, augmentation rhinoplasty is especially common, where alloplastic implants are used much more commonly than autologous tissues. In rhinoplasty, such artificial materials include silicone, expanded polytetrafluoroethylene (ePTFE), porous high-density polyethylene (pHDPE), and acellular human dermis. As the use of implants has become increasingly common in rhinoplasty, more adverse effects such as infection, extrusion, movement, irregularities, absorption, prolonged swelling, seroma, and contracture have been recognized and reported in the literature. Surgeons should be able to recognize these probable complications and manage them successfully. Early detection and prompt management of the complication are essential for minimizing the severity of the deformity. Proper management of complications is key for the success of dorsal augmentation using alloplastic implants.

Surgical outcomes and complications of septal extension graft supported by 3D printed polycaprolactone plate.

BACKGROUND: Tip plasty using a septal extension graft (SEG) is useful in the Asian population. However, complications such as decreased tip projection, infection, or deviation are noted post-surgery, and additional support using an SEG is often necessary. We aimed to transplant an additional 3D printed polycaprolactone (PCL) graft to the tip plasty using the SEG to reinforce the SEG. METHODS: The study included 43 patients (20 males and 23 females; mean age, 28.7 years; range, 17-58 years) who received rhinoplasties using the SEG method combined with a 3D printed PCL graft from November 2016 to August 2017. The mean observation period was 14.8 months (range, 12-20 months). RESULTS: Twenty-six patients rated their satisfaction level as excellent, 13 rated good, 3 rated fair, and 1 rated poor. In total, 28 patients did not exhibit tip drooping at the 1-year follow-up; 13 patients demonstrated mild to moderate tip drooping, and 2 patients demonstrated severe tip drooping. Thirty-one patients demonstrated "stiffness" of the nasal tip, of which 11 patients reported discomfort, and 20 patients reported none; two patients demonstrated deviation of the tip. CONCLUSION: Although the 3D-printed PCL graft provided support, biocompatibility, and manipulability, care is required to prevent complications.

Management of the paralyzed face using temporalis tendon transfer via intraoral and transcutaneous approach: Temporalis tendon transfer.

Temporalis tendon transfer is a technique for dynamic facial reanimation. Since its inception, nearly 80 years ago, it has undergone a wealth of innovation to produce the modern operation. Temporalis tendon transfer is a relatively minimally invasive technique for the dynamic reanimation of the paralyzed face. This technique can produce significant and appropriate movement of the lateral oral commissure, more closely mimicking the normal side. The aim of this article is to review the technique of temporalis tendon transfer involving transferring of the coronoid process of the mandible with the insertion of the temporalis tendon via intra-oral and transcutaneous approach.

Alar Base Reduction and Alar-Columellar Relationship.

Nasal base modification can improve nostril shape and orientation, reduce alar flaring, improve nasal base width, correct nasal hooding, improve symmetry, and create overall facial harmony. For the correction of alar rim deformities, careful examination, consultation, and analysis and consideration of the condition of the skin are essential. Understanding the ala and surrounding tissue, supporting the lower lateral cartilage, and selecting the proper technique produce functionally and aesthetically good results.

During surgery, the exact shape of the frontal sinus was duplicated using a surgical navigation system. METHODS: In this case report, the authors suggest intraoperative surgical navigation systems are useful for accurately determining the dimensions of the frontal sinus for osteoplastic flap surgery. RESULTS: The patient underwent successful and safe osteoplastic flap surgery using a surgical navigation system. CONCLUSION: Surgical navigation is useful and safe for frontal sinus osteoplastic flap surgery.

Height Changes of Tutoplast-Processed Fascia Lata Over Time After Dorsal Augmentation During Rhinoplasty.

PURPOSE: Tutoplast (Tutogen Medical, Neunkirchen am Brand, Germany)-processed fascia lata (TPFL) has been used for dorsal augmentation in rhinoplasty in the Republic of Korea for approximately 10 years, but few studies have described changes in TPFL in terms of dorsal height over time. We investigated changes in dorsal height after TPFL use as a dorsal implant material during rhinoplasty. MATERIALS AND METHODS: The records of 18 rhinoplasty patients who had undergone dorsal augmentation with TPFL were examined retrospectively. The patients had undergone rhinoplasty from March 2008 to June 2012. Two different ear, nose, and throat doctors analyzed the first follow-up photographs (2 lateral views and 2 oblique views) taken at approximately 1 month postoperatively and the last follow-up photographs taken from 18 to 75 months after surgery. The last follow-up photographs were classified as showing no nasal dorsal height change, slight change, and marked change compared with the first follow-up photographs. RESULTS: Of the 18 patients enrolled, 50% (n = 9) showed no change in the nasal dorsum whereas 33% (n = 6) showed mild depression and 17% (n = 3) showed marked depression of the nasal dorsum at last follow-up. CONCLUSIONS: About half of the patients who had undergone dorsal augmentation using TPFL during rhinoplasty showed mild or marked dorsal depression over time. It is recommended that TPFL be used with another implant during augmentation rhinoplasty or TPFL be used only for a slightly depressed nose. In addition, patients should be informed that TPFL could be resorbed over time.

Clinical Outcome and Patients' Satisfaction Study After Otoplasty Using Hybrid Techniques in Adult Patients.

OBJECTIVES: There are limited data on the effect of otoplasty on health-related quality of life (HRQoL) in prominent ears. There are no data on the effect of otoplasty on Glasgow Benefit Inventory (GBI) of otoplasty using hybrid techniques in adult patients. METHODS: This study involved 28 patients who underwent otoplasty using combined procedures. We chose the GBI because it is a sensitive tool for detecting changes in health status following an intervention. Patients older than 13 years received the GBI, being retrospective well-validated questionnaires for measuring the effect of otorhinolaryngologic interventions, and particularly plastic surgery procedures, on HRQoL. An individual questionnaire was created by the standard GBI. We combined posterior auricular skin excision, Mustarde suture technique, and conchomastoid suture techniques for maximizing the cosmetic improvements. RESULTS: According to the results of this study, good outcomes with patient satisfaction were achieved with this hybrid procedure. We found a conspicuous improvement in GBI total score as well as in the general health subscale after otoplasty. This indicates the beneficial impact on the healthy self-perception of this surgical procedure with prominent ears. CONCLUSIONS: In our retrospective assessment, GBI turned out to be a very useful and valuable tool in the evaluation of otoplasty. We demonstrated a long-lasting improvement in HRQoL after otoplasty for the prominent ears. Hybrid techniques are effective and satisfying treatment methods with high success rates for patients with prominent ears.

Comparison of titanium and biodegradable plates for treating midfacial fractures.

PURPOSE: The purpose of the present study was to evaluate the use of titanium plates and screws (TPSs) versus biodegradable plates and screws (BPSs) for fixation of midfacial fractures. In addition, complications related to the plates and rates of secondary surgery for plate removal were compared. PATIENTS AND METHODS: From March 2005 to March 2012, 109 patients were enrolled in this study. Fifty-six patients with TPSs implanted to fix midfacial fractures (group A) and 53 patients with BPSs to treat midfacial fractures (group B) were evaluated. Patients' histories of plate-related nonunion, infection, displacement, pain, and palpability and secondary surgery for plate removal were checked. RESULTS: None of the study participants developed nonunion issues related to the TPSs or BPSs. Six patients in group A developed complications associated with TPSs and 5 patients underwent secondary surgery for plate removal. One patient (1.8%) had a plate-related infection, 1 patient (1.8%) developed plate extrusion, 1 patient (1.8%) had plate-associated chronic pain, 2 patients (3.6%) complained of palpability, and 2 patients (3.6%) developed psychological problems (1 patient developed 2 complications). In contrast, only 1 patient in group B (2%) complained of temporary palpability, and this problem disappeared over time. None of the patients in group B complained of any other problems. CONCLUSIONS: The results indicated that BPSs and TPSs have the potential for successfully treating midfacial fractures. BPSs are suitable for treating midfacial fractures and could serve as an alternative for TPSs in selected cases.

Complications of septal extension grafts in Asian patients.

IMPORTANCE Nasal tip-plasty is one of the most important and difficult parts of rhinoplasty. Three-dimensional positioning of the nasal tip is a vital component in the overall appearance of the tip. The use of a septal extension graft (SEG) is a versatile technique that can supply nasal tip support and aid in positioning of the tip, as well as provide projection and lengthening. However, complications with this method can occur, and the incidence of these issues has risen with the increased use of this technique. OBJECTIVE To investigate the problems resulting from nasal tip surgical procedures using an SEG. DESIGN, SETTING, AND PARTICIPANTS This study involved a retrospective review of 44 consecutive patients who underwent nasal tip-plasty using an SEG. Patient results were analyzed with medical record review, patient questionnaires, and preoperative and postoperative photographs. Anthropometric measurements and analysis were performed for the pre- and postoperative tip projection and nasolabial angle. MAIN OUTCOMES AND MEASURES Prevalence of different complications of SEGs in Asian patients. RESULTS Eighty-six percent of the patients who had SEGs were satisfied with the cosmetic appearance of their nasal tip. Septal cartilage was the most frequently used material for SEGs. Complications in patients who had SEGs included nasal tip stiffness (45.5%), a decrease of projection (45.5%), nasal tip deviation (11.4%), and infection (4.5%). The revision rate was 9.0%. CONCLUSIONS AND RELEVANCE Asian nasal tip-plasty using an SEG can result in successful outcomes, providing nasal tip support, projection, and length. However, care needs to be taken to prevent complications such as hardness, loss of projection, nasal tip deviation, and infection.

Effect of various facial angles and measurements on the ideal position of the nasal tip in the Asian patient population.

IMPORTANCE: Successful surgical correction of nasal tip position requires preoperative analysis. Perceived adequate nasal tip position depends on its relationship with other facial features. Nasal tip position can be affected by the subnasal contour, proportion of facial height, and relative facial size and shape. The relation of these factors to the nasolabial angle may not be as important as previously believed. OBJECTIVE: To investigate and compare the factors affecting the ideal location of the tip of the nose in Asian patients using standard photographic measurements. DESIGN: We analyzed measurements of profile photographs and compared different factors that affect nasal tip location, including the nasofrontal, nasolabial, nasomental, and Legan angles and the ratios of the dorsal height to tip projection, the radix height to tip projection, the glabella to subnasale, and the subnasale to mentum. SETTING AND PARTICIPANTS: One hundred men, 100 women, 20 to 40 years old, seen for rhinoplasty at the Department of Otorhinolaryngology, Chosun University College of Medicine. MAIN OUTCOME AND MEASURES: Contribution of different facial measurements to the ideal nasal tip position. RESULTS: Nasolabial and nasomental angles exerted a statistically significant effect on ideal nasal tip position, whereas the Legane angle, the ratio of midface to lower face, and the ratio of nasal length to lower face did not show significant effects on nasal tip position. CONCLUSIONS AND RELEVANCE: The nasolabial and nasomental angles have important effects on ideal nasal tip position and should be considered together during preoperative evaluation of the location of the nasal tip. Concurrent genioplasty should optimize rhinoplasty outcomes in appropriately selected patients. LEVEL OF EVIDENCE: NA.

Clear cell myoepithelial carcinoma in the base of the tongue: Case report and review of the literature.

Clear cell myoepithelial carcinoma is a very rare disease which develops primarily in the parotid gland. To date, only 17 cases of clear cell myoepithelial carcinoma have been reported worldwide. Among them, only three cases developed in the minor salivary gland in the oral cavity. No cases developed in the base of the tongue. Here, we report a new case of clear cell myoepithelial carcinoma that developed in the tongue base of a 52-year-old female patient. A mass was discovered on the left side of the tongue base. We successfully removed the mass through suprahyoid pharyngotomy approach. The light microscopy examination and various immunohistochemical stainings revealed clear cell myoepithelial carcinoma. During a two year follow-up period, there was no recurrence or local or distant metastasis.

Nasal hemangiopericytoma causing oncogenic osteomalacia.

Oncogenic osteomalacia is a rare cause that makes abnormalities of bone metabolism. Our case arose in a 47-year-old woman presenting a nasal mass associated with osteomalacia. We excised the mass carefully. After surgery, it was diagnosed as hemangiopericytoma and her symptoms related with osteomalacia were relieved and biochemical abnormalities were restored to normal range. We report and review a rare case of nasal hemangiopericytoma that caused osteomalacia.

Granular cell tumor on larynx.

Granular cell tumors (GCTs) are uncommon neoplasm. They can originate in any part of the body. The most common sites of origin are in the head and neck, while the larynx is a relatively uncommon location. Patients affected with a laryngeal GCT typically present with persistent hoarseness, stridor, hemoptysis, dysphagia, and otalgia but, the tumor may be asymptomatic. Care must be taken to differentiate this lesion from others due to the presence of pseudo-epitheliomatous hyperplasia which overlies the GCT and may occasionally mimic squamous cell carcinoma. Therefore, a confirmative diagnosis should be made histopathologically and should be supported by immunohistochemical staining. These tumors are treated by complete surgical resection. Examining the complete removal of the tumor through securing a negative free margin is considered to be a consequential procedure. We experienced a 64-yr-old man with a laryngeal granular cell tumor involving the right true vocal cord. He was treated by surgical resection under a fine dissection laryngomicroscope. Here we present this case and a review of literature.

Clinical significance of the expression of galectin-3 and Pim-1 in laryngeal squamous cell carcinoma.

BACKGROUND: Because advanced-stage squamous cell carcinoma of the larynx undergoes a generally poor hospital course, the prognostic significance of squamous cell carcinoma in the larynx was evaluated to identify those features associated with aggressive biologic behaviour according to the immunologic and histopathologic characteristics. Molecular prognostic and predictive factors have been extensively studied in different cancers over the past decades, and some of these factors were found to be useful in diagnosis, follow-up, or even treatment of some malignant tumours. AIMS: To concretize the pathogenesis of malignant tumours in the larynx and to examine the possible prognostic factors related to malignancy. METHODS: To assess the significance of galectin-3 and Pim-1 protein in laryngeal tumours and their correlation with prognostic factors, samples from 77 patients with squamous cell carcinoma of the larynx were studied immunohistochemically. We examined the correlations of galectin-3 and Pim-1 protein expression according to tumour stage, nodal status, clinical stage, and histologic differentiation to investigate the clinical significance. RESULTS: Squamous cell carcinoma showed increased galectin-3 and Pim-1 expression in the more advanced clinical stage, tumour stage, and nodal status. CONCLUSIONS: The pathogenetic role of galectin-3 and Pim-1 expression in laryngeal squamous cell carcinoma indicates that galectin-3 and Pim-1 might be used as a possible prognostic factor.

Galectin-8 expression in laryngeal squamous cell carcinoma.

OBJECTIVES: Despite the ongoing development of treatment protocols for laryngeal squamous cell carcinoma (LSCC), the patients suffering with this malady have shown only a modestly improved outcome. This poor outcome has been attributed to the lack of therapy that's individualized to the tumor's biological properties. Various studies have showed that galectin-8 is widely expressed in tumor tissues as well as in normal tissues, and the level of the galectin-8 expression may correlate with the malignancy of human squamous cell carcinoma. The purpose of this study is to evaluate the expression of galectin-8 and to investigate its correlations with the primary stage, the nodal involvement, the clinical stage and the histologic grade of squamous cell carcinoma of the larynx. METHODS: The paraffin-embedded tissue specimens from 77 patients who were diagnosed as LSCC between 1993 and 2007 were immunohistochemically stained for galectin-8. RESULTS: Immunohistochemical analysis showed that a strong positive expression of galectin-8 was correlated with the T-stages, the nodal stages and the clinical stages. However, the histopathologic grades were not correlated with the galectin-8 expression in LSCC. CONCLUSION: The expression of galectin-8 protein can be used as a prognostic factor for patients with LSCC.
