21.7%), while trauma was the most common source of infection (26.1%). Most patients were treated successfully with combined surgical debridement and antibiotics (73.9%). Significant differences between acute and chronic orbital osteomyelitis patients include clinical presentation, use of magnetic resonance imaging, methicillin-resistant Staphylococcus aureus infection, and procedure only treatments. The studies reviewed here provide a comprehensive overview of the clinical presentation, infection sources, diagnostic modalities, common organisms, and treatment options involved in pediatric orbital osteomyelitis.

Acalvaria, also known as acrania, is a rare congenital anomaly which is characterized by a complete or partial defect of the calvarium. Due to the low number of patients reported, there is no a standard for the treatment of this condition; thereby, the objective is to present a new surviving patient with acalvaria and a novel surgical approach to treat it, giving craniofacial surgeons and neurosurgeons more tools to face it. In this article, the authors present a reproducible surgical approach in patients with partial acalvaria, which consist in use the present bone as a graft to cover the defect, giving a temporal but stable coverture. No other calvaria graft has been published along the available literature, since only around 4 patients are acalvaria survivors worldwide. However, the authors need to make a longer follow-up to establish the usefulness of the technique in long term. Other limitation is the future procedures needed to a better function and aesthetic.

Deformations can be treated non-surgically, when diagnosed early, whereas malformations surgically only. The authors use the EarWell system proven to achieve excellent results in treating deformations. Although prematurity might raise the risk of ear-deformations compared to term infants, in our experience, there is a longer time frame until effective treatment is initiated due to the cartilage malleability.Treatment included splinting with retractors and taping or a custom-made silicone ear-mold if necessary. Patients were examined weekly, and treatment continued until appropriate ear shape was achieved (6-14 weeks).The authors treated 8 preterm infants during 2018 to 2020 with the above method. buy INCB39110 Average age of application was 9.25 weeks; treatment was initiated in all patients before the age of 12 weeks. 5/8 had a right-side, 2/8 a left-side, and one a bilateral deformation. Average treatment duration was 10 ± 2.9 weeks. Assessment of satisfaction was made by parents via phone questionnaires; most were pleased with the overall result, while 62% were extremely satisfied.The authors observed higher compliance and longer-lasting malleability of the cartilage in preterm compared to term-infants. They also had fewer complications than in the term group, maybe due to their older (actual age), and more resistant and durable skin compared to a term-infant of the same age. The authors recommend initiating treatment in preterm infants later than accepted practice as results were excellent, and despite the longer treatment duration, this is a better treatment option than surgery.The recurrence of chronic subdural hematoma (CSDH) is high post-treatment. In this study, we aimed to construct individualized models for prediction of the postoperative recurrence of CSDH in patients underwent twist-drill craniostomy combined with urokinase (UK) instillation. In total, 183 patients with CSDH were retrospectively enrolled. In summary, 21 candidate factors were retrieved from past medical records. The least absolute shrinkage and selection operator regression was adopted to reduce the high dimensionality of data. Four predictors preoperative hematoma volume, encephalatrophy, brain re-expansion, and UK instillation frequency were filtered from the 21 candidate factors using the least absolute shrinkage and selection operator method. Binary logistic regression model was employed to establish preoperative and postoperative prediction models. The preoperative model included preoperative hematoma volume and encephalatrophy whereas the postoperative model included brain re-expansion and UK instillation frequency. The predictive performance of the nomograms was evaluated by the receiver operating characteristic curve and calibration chart. Area under curve of the preoperative and postoperative models were 0.755 (95% confidence interval 0.690-0.889) and 0.782 (95% confidence interval 0.720-0.936), respectively, indicating good discrimination ability. The calibration results showed good fitting between the predicted probability and the actual probability. Finally, a decision curve analysis revealed excellent clinical performance of the proposed nomograms. Functionally, the preoperative model was used to identify high-risk patients with CSDH and application of UK, while the postoperative model was applied to guide physician-patients communication during follow-up. These 2 prediction models provide a basis for further clinical and experimental studies.The aim of this study was to analyze lip shapes as represented in the British edition of Vogue over the last century (1916-2015). Photographs containing distinguishable lips were selected from a book entitled Vogue 100 A Century of Style. A total of 98 frontal pictures (20 males, 78 females) in which the lips and mouth were identifiable were included and analyzed in terms of 4 lip-related ratios (lip thickness-to-width ratio [LTW]; upper-to-lower vermillion ratio [ULR]; upper vermillion thickness-to-upper lip height ratio [VUL]; and lip-to-nose width ratio [LNW]). The LTW was 0.39 ± 0.07, and did not vary significantly over time (P = 0.261 [linear regression analysis]). The LTW of women (0.41 ± 0.07) was significantly greater than that of men (0.34 ± 0.05) (P  less then  0.001 [independent 2-samples t-test]). The ULR was 0.74 ± 0.16, and did not vary significantly over time (P = 0.647). There was no significant difference in the ULR between men (0.75 ± 0.10) and women (0.74 ± 0.17) (P = 0.769). The VUL was 0.43 ± 0.09, and did not vary significantly over time (P = 0.550). link2 The VUL of women (0.44 ± 0.09) was significantly greater than that of men (0.37 ± 0.06) (P = 0.001). The LNW was 1.49 ± 0.19, and did not vary significantly over time (P = 0.619). There was no significant difference in the LNW between men (1.43 ± 0.16) and women (1.51 ± 0.19) (P = 0.082). The results of this study may be useful for planning facial rejuvenation operations, as well as for clinical practitioners dealing with brow esthetics or lip tattooing.The purpose of this study was to develop a quantitative AR-assisted free-hand orthognathic surgery method using electromagnetic (EM) tracking and skin-attached dynamic reference. The authors proposed a novel, simplified, and convenient workflow for augmented reality (AR)-assisted orthognathic surgery based on optical marker-less tracking, a comfortable display, and a non-invasive, skin-attached dynamic reference frame. The 2 registrations between the physical (EM tracking) and CT image spaces and between the physical and AR camera spaces, essential processes in AR-assisted surgery, were pre-operatively performed using the registration body complex and 3D depth camera. The intraoperative model of the maxillary bone segment (MBS) was superimposed on the real patient image with the simulated goal model on a flat-panel display, and the MBS was freely handled for repositioning with respect to the skin-attached dynamic reference tool (SRT) with quantitative visualization of landmarks of interest using only EM tracking. To evaluate the accuracy of AR-assisted Le Fort I surgery, the MBS of the phantom was simulated and repositioned by 6 translational and three rotational movements. The mean absolute deviations (MADs) between the simulation and post-operative positions of MBS landmarks by the SRT were 0.20, 0.34, 0.29, and 0.55 mm in x- (left lateral, right lateral), y- (setback, advance), and z- (impaction, elongation) directions, and RMS, respectively, while those by the BRT were 0.23, 0.37, 0.30, and 0.60 mm. There were no significant differences between the translation and rotation surgeries or among surgeries in the x-, y-, and z-axes for the SRT. The MADs in the x-, y-, and z-axes exhibited no significant differences between the SRT and BRT. The developed method showed high accuracy and reliability in free-hand orthognathic surgery using EM tracking and skin-attached dynamic reference.Subcutaneous rehydration is an optional infusion route in hospitalized older adults. This meta-analysis sought to compare the effectiveness of subcutaneous versus intravenous (IV) fluid administration to reverse mild-to-moderate dehydration in hospitalized older adults. link3 A literature search was performed. No restrictions were imposed regarding language. Three randomized clinical trials conducted with patients 60 years of age or older treated with subcutaneous or IV rehydration were included, with a total sample size of 197 patients. Controlled quasi-randomized and crossover trials were excluded. The primary end point was reversal of dehydration. Secondary end points were patient satisfaction and frequency of adverse events (eg, cellulitis, edema, phlebitis, erythema, hyponatremia, and pain). Both treatments were effective in rehydrating the patients within 48 hours, with no statistically significant difference between the groups. Subcutaneous fluid administration effectively reversed dehydration while protecting against phlebitis. Since the quality of evidence was considerably low, further multicenter randomized clinical trials of efficient methodological quality should be conducted to consolidate the body of evidence.All nurses who care for neonates with peripherally inserted central catheters require enhanced awareness of the current practice guidelines and standards. This study evaluated the impact of an educational program on nurses' performance from May 2016 to July 2017 at 4 hospitals in Tehran, Iran. The performance of 80 nurses was observed and scored 3 times before the intervention. Four weeks after the last training session, their performance was observed with the same researcher, and the checklist was completed 3 times in different working shifts. Four 35- to 45-minute training sessions were completed with a 4-week follow-up. Results of the study indicated that training courses should be held every 6 months, including permanent or periodic feedback.
