RESUMO

Facial palsy can result in a serious complication known as facial synkinesis, causing both physical and psychological harm to the patients. There is growing evidence that patients with facial synkinesis have brain abnormalities, but the brain mechanisms and underlying imaging biomarkers remain unclear. Here, we employed functional magnetic resonance imaging (fMRI) to investigate brain function in 31 unilateral post facial palsy synkinesis patients and 25 healthy controls during different facial expression movements and at rest. Combining surface-based mass-univariate analysis and multivariate pattern analysis, we identified diffused activation and intrinsic connection patterns in the primary motor cortex and the somatosensory cortex on the patient's affected side. Further, we classified post facial palsy synkinesis patients from healthy subjects with favorable accuracy using the support vector machine based on both task-related and resting-state functional magnetic resonance imaging data. Together, these findings indicate the potential of the identified functional reorganizations to serve as neuroimaging biomarkers for facial synkinesis diagnosis.

RESUMO

PURPOSE: Dermatochalasis with lateral hooding and medial orbital fat loss are common signs of aging in the upper eyelid. Removing the excess skin in this area through infrabrow skin excision can effectively lift the loose skin of the upper eyelid and minimizes visible scarring. Additionally, we have identified three compartments of orbital fat prolapse based on orbital anatomy. Transferring volume from the lateral compartment to the intermediate region can flatten the lateral upper eyelid and create medial fullness, which ultimately rejuvenates the upper eyelid. This study presents an operative method for correcting age-related changes in the upper eyelid using this technique. METHODS: A total of 34 eyelids from 17 patients underwent a surgical procedure involving infrabrow skin excision, along with repositioning and lifting of lateral orbital fat. The inclusion criteria consisted of patients with moderate to severe upper eyelid dermatochalasis, coupled with middle fat loss and lateral hooding. To correct lateral hooding and restore midfacial fullness, lateral orbital fat was repositioned to an intermediate position, and the orbicularis oculi muscle was fold-sutured to the corrugator supercilii muscle. RESULTS: The mean age of the patients was 55.59 ± 3.20 years, with a range of 48 to 61 years. The mean follow-up period was 9.94 ± 1.35 months, ranging from 8 to 12 months. Patients were evaluated at 1-month, 3-month, and 6-month intervals. The Strasser system was used to evaluate the surgical outcomes at 3 months. All patients achieved good surgical outcomes, expressed through satisfactory cosmetic improvements, and improved visual field. The procedure effectively corrected lateral hooding and loss of middle orbital fat through infrabrow skin excision. No complications, such as wound dehiscence, lagophthalmos, noticeable scarring, ocular dyskinesia, or sensory changes, were observed. CONCLUSIONS: The combination of infrabrow skin excision, repositioning of lateral orbital fat, and lifting of the orbicularis oculi muscle effectively addresses moderate to severe dermatochalasis, lateral hooding, medial fat loss, and improves elasticity of the anterior wall of the upper lid in our patients. This procedure can produce satisfactory and long-lasting aesthetic results with an inconspicuous scar beneath the brow.

RESUMO

OBJECTIVES: Aim to evaluate the incidence and characteristics of nontraumatic dehiscence of the lamina papyracea (LP) via computed tomography (CT). METHODS: The authors retrospectively studied 893 patients' history and paranasal sinus CT from February to September 2020. The datum of incidence and the characteristics of LP dehiscence were collected and analyzed. RESULTS: The LP dehiscence was identified in 23 of 893 patients (2.58%). Lamina papyracea anatomical variations were categorized into Grade I, II, and III, which account 69.56%, 21.74%, and 8.70% of the entire dehiscence group. The average depth of LP ingression was 5.5 ± 0.7 mm. There was no statistical difference between bilateral incidence. The medial rectus muscle was involved in 3 lesions. In all CT reports, this anatomic variation was misdiagnosed as ethmoid sinusitis in 8 cases. CONCLUSIONS: Preoperative cognition of the anatomic variation of LP via CT is conducive to decrease misdiagnosis and postoperative complications.

RESUMO

OBJECTIVE: The objective of this investigation was to describe the characteristics of the current cleft treatment situation in a hospital-based cleft center in Shanghai and provide references to clinical diagnosis, treatment, and nursing. METHODS: A total of 1584 patients from the Center for Cleft Lip and Palate, Department of Oral and Cranio-Maxillofacial Science, Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine during June 2006 to February 2008 were analyzed retrospectively. Data regarding sex, native place, type of cleft, cleft side, accompanied malformations, family history, and age at surgery were analyzed in detail. Length of stay after surgery, the primary operation fee, and some other hospitalized information were also investigated. RESULTS: From 1584 patients(1590 operations; 6 patients had 6 operations), there were 939 male and 645 female patients (M:F = 1.46:1). The number of Shanghai local patients is 249 (15.72%), whereas the other 1335 patients were from out of Shanghai. Approximately 15% of the patients had certain family history. The age at operating varied from 2 months to 36 years; the mean value was 6.95 years. The postoperation hospital stay varied from 1 day to 15 days; the mean value was 5.54 days. The primary operation fee was 235 to 673 USD depending on the different surgical procedures. The number of cleft types or other malformation, which had not been treated in the statistics varied from zero to 3; the mean value was 0.4375. The cleft morphology was classified as follows: cleft lip, 591 cases (37.31%); cleft palate, 651 cases (41.10%); alveolar cleft, 144 cases (9.10%); facial traverse cleft, 27 cases (1.70%); velopharyngeal insufficiency, 105 cases (6.63%); velocardiofacial syndrome, 57 cases (3.60%); and Pierre Robin sequence, 15 cases (0.95%). In all the classifications, left was more than right (L:R = 2.10:1). CONCLUSION: As a busy hospital-based cleft care center, most of the patients are from out of Shanghai. The current multidisciplinary protocol for cleft care in such specialist cleft center is cost-effective. There may be a tendency that the patients with cleft palate are more than the patients with cleft lips in recent years, which may due to the popularization of prenatal examination in China.

RESUMO

BACKGROUND: There is growing evidence that tripartite motif-containing protein 44 (TRIM44) plays crucial role in tumor development. However, the underlying mechanism of this deubiquitinating enzyme remains unclear. METHODS: Large clinical samples were used to detect TRIM44 expression and its associations with clinicopathological features and prognosis. Gain- and loss-of-function experiments in cell lines and mouse xenograft models were performed to elucidate the function and underlying mechanisms of TRIM44 induced tumor progression. Co-immunoprecipitation (Co-IP) assays and mass spectrometric analyses were applied to verify the interacting proteins of TRIM44. RESULTS: We found that TRIM44 was commonly amplified in melanoma tissues compared with paratumoral tissues. TRIM44 expression also positively correlated with more aggressive clinicopathological features, such as Breslow depth (p = 0.025), distant metastasis (p = 0.012), and TNM stage (p = 0.002). Importantly, we found that TRIM44 was an independent indicator of prognosis for melanoma patients. Functionally, overexpression of TRIM44 facilitated cell invasion, migration, apoptosis resistance and proliferation in vitro, and promoted lung metastasis and tumorigenic ability in vivo. Importantly, high level of TRIM44 induced melanoma cell epithelial-mesenchymal transition (EMT), which is one of the most important mechanisms for the promotion of tumor metastasis. Mechanistically, high levels of TRIM44 increased the levels of p-AKT (T308) and p-mTOR (S2448), and a specific AKT inhibitor inhibited TRIM44-induced tumor progression. Co-IP assays and mass spectrometric analyses indicated that TRIM44 overexpression induces cell EMT through activating AKT/mTOR pathway via directly binding and stabilizing TOLL-like receptor 4 (TLR4), and TLR4 interference impeded TRIM44 induced tumor progression. Moreover, we demonstrated that TRIM44 is the target of miR-26b-5p, which is significantly downregulated in melanoma tissues and may be responsible for the overexpression of TRIM44. CONCLUSIONS: TRIM44, regulated by miR-26b-5p, promotes melanoma progression by stabilizing TLR4, which then activates the AKT/mTOR pathway. TRIM44 shows promise as a prognostic predictor and a therapeutic target for melanoma patients.
