The Relationship Between Morphometric Measurements, Severity, and Success of Zygomatic Arch Fracture Reduction.

PURPOSE: Identify associations between preoperative radiographic measurements and clinical findings of zygomatic arch fractures and postoperative radiographic measurements. Based on those findings, propose a comprehensive treatment algorithm for the solitary zygomatic arch fracture and combined zygomatic arch-zygomatic complex fracture. METHODS: Retrospective cohort study with patients referred to our department for zygomatic arch fractures between 2013 and 2018. Data analyzed included patient demographics, clinical evaluation, and radiographic information. Predictor variables were preoperative morphometric measurements: the initial latero-lateral (LL) defect was determined by the difference between the preoperative LL distances of the fractured and the healthy arches, LL distance was measured from the midsagittal plane in the cranium to the inner cortex of the most displaced arch segment, initial arch coronoid distances were measured from the medial part of the most dislocated arch fragment to the lateral aspect of the coronoid, and the anterior-posterior telescoping was measured as the distance between the 2 points in the arch that lost continuity and overlapped as a result of the fracture. The outcome was defined as the residual defect. It was calculated as the ratio between the postoperative remaining LL distance and the initial LL defect. RESULTS: A total of 179 cases were enrolled, all involving head residual defects. Statistical analysis was performed only on 149 medially displaced fractures. Results show that an initial LL defect larger than 3.5 mm has an 86.3% chance of remaining with a better residual defect (<84.1%), P = .001. Cases with antero-posterior (AP) telescoping > 1.45 mm showed a 72.4% chance of remaining with a poor residual defect >84% (P = .003). Arch-coronoid initial distance showed little effect on the chance of remaining with a large remining defect (P = .417, CI = 95%) CONCLUSION: Based on our results, we found that morphometric measurements can be used to predict the reduction results and can assist the clinician in choosing the optimal reduction method and thus increasing the success rate.

The Relationship Between Morphometric Measurments, Severity and Success of Zygomatic Arch Fracture Reduction.

PURPOSE: Zygomatic arch fractures are commonly treated by closed reduction. This kind of treatment is highly influenced by the treating surgeon and type of fracture. Thus, it is important to choose the optimal treatment for different fractures. Current treatment schemes for zygomatic arch fractures reduction are based on subjective assessments. We believe this approach should be refined. Create a new treatment algorithm for the solitary and combined zygomatic arch fractures based on radiological morphometric measurements. This will assist the clinician in tailoring a suitable treatment for each case and avoiding pitfalls, thus achieving best possible results. METHODS: A total of 179 radiologic images of patients treated in our department for zygomatic arch fractures were morphometrically measured and analyzed. RESULTS: Three variables showed a capacity to predict a large remaining defect; The presence of a preoperative esthetic defect and a large initial latero-lateral (LL) defect reduced the probability of a large remaining defect (OR = 0.289, P= .019; (OR = 0.78, P= .008; respectively). Patients with initial LL defect < 3.5 mm presented postoperative residual defect 3-times greater than patients with initial LL defect > 3.5 mm A large antero-posterior telescoping increased the probability of a large remaining defect (OR = 1.27 P= .003). Cases that had antero-posterior telescoping > 1.45 mm had a 72.4% probability of remaining with a poor residual defect > 84.1% (P= .003). CONCLUSIONS: Based on our results we believe that the use of morphometric measurements is important when assessing zygomatic arch fractures. We found that there are measurements that can be used to predict esthetic and functional defects, as well as probability of resolving them. Morphometric measurements can be used to predict the reduction difficulty and can assist the clinician in choosing the optimal reduction method and thus increasing the success rate.

Dietary advice and oral nutritional supplements do not increase survival in older malnourished adults: a multicentre randomised controlled trial.

Objectives: The study aimed to investigate the effect on survival after 6 months of treatment involving individual dietary advice and oral nutritional supplements in older malnourished adults after discharge from hospital.Methods: This multicentre randomised controlled trial included 671 patients aged 65 years who were malnourished or at risk of malnutrition when admitted to hospital between 2010 and 2014, and followed up after 8.2 years (median 4.1 years). Patients were randomised to receive dietary advice or oral nutritional supplements, separate or in combination, or routine care. The intervention started at discharge from the hospital and continued for 6 months, with survival being the main outcome measure.Results: During the follow-up period 398 (59.3%) participants died. At follow-up, the survival rates were 36.9% for dietary advice, 42.4% for oral nutritional supplements, 40.2% for dietary advice combined with oral nutritional supplements, and 43.3% for the control group (log-rank test p = 0.762). After stratifying the participants according to nutritional status, survival still did not differ significantly between the treatment arms (log-rank test p = 0.480 and p = 0.298 for the 506 participants at risk of malnutrition and the 165 malnourished participants, respectively).Conclusions: Oral nutritional supplements with or without dietary advice, or dietary advice alone, do not improve the survival of malnourished older adults. These results do not support the routine use of supplements in older malnourished adults, provided that survival is the aim of the treatment.Trial registration: ClinicalTrials.gov with ID: NCT01057914.

Necrotizing sialometaplasia of the palate in a young bodybuilder with anabolic androgenic steroids abuse.

Necrotizing sialometaplasia is a benign, self-limiting, inflammatory disease of salivary glands, mainly involving the minor salivary glands in the palate. This lesion can mimic a malignant neoplasm, both clinically and histopathologically, manifesting as a submucosal swelling or as an ulcer of the palate. This report presents a case of an otherwise healthy bodybuilder with anabolic androgenic steroids abuse with bilateral necrotizing sialometaplasia in the palate, and discusses computed tomography findings in the pre-ulceration phase. Literature review revealed another two cases of necrotizing sialometaplasia with preoperative imaging, both performed in the ulceration phase. The importance of radiographic findings as an aid in differential diagnosis is further discussed, as well as the role of possible predisposing factors including anabolic androgenic steroids abuse in the pathogenesis of necrotizing sialometaplasia.

Mealtime habits and meal provision are associated with malnutrition among elderly patients admitted to hospital.

BACKGROUND & AIMS: Large-scale studies performed in hospitals with the validated Mini Nutritional Assessment (MNA) tool are scarce. However, factors associated with malnutrition are important for identifying individuals at risk. The aims of the present study were to estimate the prevalence of malnutrition and to examine the association between mealtime habits, meal provision, and malnutrition among elderly patients admitted to hospital. METHODS: This cross-sectional study included patients aged ≥65 years admitted to internal medicine, surgical or orthopaedic wards. The MNA was used for their nutritional assessment, and factors potentially associated with malnutrition were recorded. RESULTS: Of 1771 patients (mean age 78 years), 35.5% were well-nourished, 55.1% were at risk of malnutrition and 9.4% were malnourished. Overnight fasts exceeding 11 h, fewer than four eating episodes a day, and not cooking independently were associated with both malnutrition and risk of malnutrition. CONCLUSIONS: The risk of malnutrition was high among elderly patients admitted to hospital, whereas the proportion with fully developed malnutrition was lower than expected. A long overnight fast, few eating episodes, and not cooking independently were associated with an increased risk of malnutrition. Knowledge of these factors when providing care to the elderly may assist health-care professionals to prevent malnutrition.
