RESUMO

Rhinogenic headache (RH), arising from nasal and sinus pathologies, present a diagnostic challenge due to their diverse etiologies. This study investigates a unique case where RH coincides with infraorbital nerve dehiscence, delving into the intricate relationship between sinonasal anatomy and neurovascular complications. The infraorbital nerve contacted a cyst in the maxillary sinus. Centripetal endoscopic sinus surgery was performed to open the maxillary sinus and remove the cyst. After 3 months of follow-up, the patient had a notable improvement in symptoms with a reduced headache. This case highlights the significance of considering uncommon anatomic variations, such as infraorbital nerve dehiscence, within the context of RH. Diligent history-taking and appropriate use of radiologic investigations are pivotal for guiding clinicians toward an accurate diagnosis and determining the most appropriate course of treatment.

RESUMO

Mastopexy and reduction mammoplasty are well-established procedures used to address ptotic and hypertrophic breasts. A variety of methods have been described in the literature for managing the three main aspects of these procedures: skin excess, parenchyma, and the nipple-areola complex (NAC). Among these techniques, several have specifically addressed the markings of the NAC in procedures involving a preoperatively established NAC position. While many of these have proven effective over time, the literature lacks standardized and reproducible methods. In this paper, we introduce, step-by-step, a novel approach based on geometrical principles to address this limitation. This method involves the simple process of drawing two hemi circumferences on the vertical limbs of the skin resection pattern, which are commonly marked using the Bisemberg maneuver or similar techniques. The method we introduce is adaptable to virtually all NAC pedicles. Furthermore, as exemplified in the accompanying video, it can be incorporated to most skin resection patterns with a preoperatively defined NAC position. The clinical application, as evidenced in the case reported, appears to be promising. Although it has some limitations, this procedure shows the potential to reduce inaccuracy by minimizing variability factors. As a result, even inexperienced surgeons can achieve precise markings.

RESUMO

Microsurgical procedures are nowadays routinely performed worldwide in reconstructive surgery. The deep inferior epigastric artery perforator (DIEP) flap has become the gold standard in breast reconstruction due to its excellent outcomes and lower donor site morbidity. However, complications, including flap failure, still occur in DIEP flap breast reconstruction. Often, according to our experience, these complications result from pedicle disorders, which can be attributed to postoperative mobilization. In the present study, we evaluated the efficacy and safety of using a fibrin sealant as a method for pedicle stabilization to prevent pedicle mobilization in the postoperative period. With our technique, after the flap insetting and microsurgical anastomosis, the pedicle was stabilized by applying a fibrin sealant (TISSEEL™) around and over the entire pedicle. Our study included a homogeneous series of 70 patients who received a delayed DIEP flap breast reconstruction. A retrospective study was conducted to evaluate this novel technique compared to the conventional method. In our experience, the fibrin glue allowed us to reduce the strain for correct pedicle positioning and all subsequent efforts to avoid displacements in the postoperative period. Our preliminary results suggest that this method may lead to a reduction in overall complications attributable to pedicle disorders.

RESUMO

Complications in aesthetic medicine can be considered a consequence of the inexperience of the performing physician, but in some cases, they can unveil far more serious conditions, hitherto silent. We present a case of a 48-year-old patient who, following botulinum toxin type A (Botox) injection for treatment of forehead wrinkles, returned to our attention 12 days later for a discrete, newly onset right eyelid ptosis. This ptosis was a telltale sign of the presence of an intracranial aneurysm closely related with the oculomotor nerve. The lack of compensatory action by the frontalis muscle in maintaining the eyelid in position allowed us to highlight the extrinsic compression deficit of the oculomotor nerve. Subsequently, the patient underwent endovascular treatment of the aneurysm, leading to complete resolution of the case.

RESUMO

Sinonasal Hemangiopericytoma (HPC) is a rare vascular tumor originated from Zimmermann's pericyte with not well valuable course. The diagnosis needs a careful ENT endoscopic examination, radiological study and histopathological analysis with immunohistochemistry for confirmation of diagnosis. We describe a case of a male patient, 67 years old, with history of repeated monolateral right epistaxis. Endoscopic and radiological examination showed an ethmoid-sphenoidal lesion which occupied the entire nasal fossa extending towards the choana, with blood supply coming from the posterior ethmoidal artery. The patient performed an extemporaneous biopsy with subsequent en-bloc removal in operating room, without prior embolization, with the Centripetal Endoscopic Sinus Surgery technique (CESS). The histopathologic analysis led to the diagnosis of sinus HPC. The patient performed close endoscopic follow-ups every 2 months, without performing radio or chemotherapy, and with no evidence of recurrence after 3 years of follow-up. Analyzing the recent literature, a more indolent course with low recurrence rates after total endoscopic surgery remotion was described. Preoperative embolization can be useful in determinate cases, but cause to different complications, it should not be ordinarily performed.

RESUMO

BACKGROUND: The reconstruction of the upper eyelid and the periorbital region is a challenge for the surgeon. The aims of this reconstruction are to guarantee protection to the eyeball, maintain the visual field, and restore the function of the eyelid without damaging other anatomical structures. In this study, the authors describe the use of a propeller myocutaneous flap based on the small vertical branches of marginal, peripheral ed superficial arcade, for the reconstruction of the upper eyelid or periorbital region. MATERIALS AND METHODS: The authors enrolled 3 patients (Caucasian), between 2018 and 2019, and subjected to reconstructive surgery with the propeller myocutaneous flap of the periorbital region at the Plastic Surgery Unit of the University of Messina. The vascularization of the flap was demonstrated through an anatomical study conducted on cadavers at the dissection laboratories of the University of Bordeaux 2. RESULTS: The authors have shown that the myocutaneous flap represents a valid alternative for loss of substance coverage and reconstruction of the upper eyelid or periorbital region, allowing the achievement of a good aesthetic and functional result. FOLLOW UP: Patients were followed up at 3-6-12 months. No complications were reported (flap retraction, periocular region deformity, donor site morbidity). Furthermore, at the last visit, the scars were almost invisible. CONCLUSIONS: The use of the propeller myocutaneous flap of the upper eyelid is a valid reconstructive alternative to the standard techniques described so far for the reconstruction of the periorbital region.

RESUMO

Patients with idiopathic gynaecomastia have greater BMI and an unfavourable lipid profile compared with age-matched controls. Twenty-five adult eugonadal patients with idiopathic gynaecomastia and 50 age- and BMI-matched controls were selected. Clinical and biochemical parameters and ultrasound testis volume were reviewed retrospectively. Patients and controls differed for no biochemical parameter, except for LH levels, which were 31% higher in patients (p = 0.019), although within the normal range. Compared with controls, patients had a threefold greater rate of elevated LDL-c (p = 0.025). Patients ≥ 25 years had higher levels of serum LDL-c compared with either patients < 25 years (p = 0.006) or controls ≥ 25 years (p = 0.012). In patients, both at bivariate analysis and at linear regression, age correlated positively with total cholesterol and LDL-c, the latter correlated inversely with total testosterone. Negative interactions were found for age and total testosterone with LDL-c, for LH and estradiol to testosterone ratio (E2:T) with LDL-c, and for age and E2:T with total cholesterol. Our data suggest inadequate local androgen action in patients with idiopathic gynaecomastia. This partial androgen resistance might blunt the beneficial effects of testosterone on lipid metabolism. Further studies are needed to verify whether this metabolic derangement impacts the cardiovascular health of these patients.

RESUMO

Frey's syndrome is the most common adverse event after parotidectomy, and usually, it appears after 6 months. In our case, symptoms appear 20 years from surgery, an uncommon condition. Intralesional botulinum toxin gives excellent results in therapy, regardless of the time elapsed between surgery and the first treatment.

RESUMO

BACKGROUND: Preclinical training in perforator flap harvesting is typically conducted on living animal models; however, repeated training is not possible with these models because of ethical and/or economical constraints. We describe an anterolateral thigh flap (ALT flap) training model using chicken thigh that seems to be an appropriate training model prior, for example, to raise a perforator flap in a living rat or swine model. METHODS: A total of 10 chicken legs were used in this study. Six chicken legs were anatomically dissected to confirm the presence of the perforator and to identify the main vascular tree. In four chicken legs, a skin flap was planned based on the perforator and intramuscular dissection was performed under magnification. RESULTS: The perforator was identified in all dissections and was consistently found 3 cm above the line extending from the patella to the head of the femur in its third proximal. Proximally, the mean diameter of the artery and vein was 0.56 (σ = 0.04) and 0.84 (σ = 0.06) mm, respectively. The mean dissection time to raise the flap was 88 (σ = 7) min. CONCLUSION: This is the first description of a nonliving biological simulation model for training in perforator flap dissection that mimics an ALT flap. As an ex vivo chicken model, it is a cost effective and readily accessible model suitable for repeated practice.

RESUMO

BACKGROUND: The lack of centralized data on severe asthma has resulted in a scarcity of information about the disease and its management. The development of a common data collection tool for the International Severe Asthma Registry (ISAR) will enable standardized data collection, subsequently enabling data interoperability. OBJECTIVES: To create a standardized list of variables for the first international registry for severe asthma via expert consensus. METHODS: A modified Delphi process was used to reach consensus on a minimum set of variables to capture in ISAR: the core variables. The Delphi panel brought together 27 international experts in the field of severe asthma research. The process consisted of 3 iterative rounds. In each round, all Delphi panel members were issued an electronic ISAR Delphi workbook to complete and return to the ISAR Delphi administrator. Workbooks and result summaries were anonymously distributed by the Delphi administrator to all panel members at subsequent rounds. Finalization of the core variable list was facilitated by 2 face-to-face meetings. RESULTS: Of the initial 747 selected variables, the Delphi panel reached a consensus on 95. The chosen variables will allow severe asthma to be assessed against patient demographics and medical history, patient-reported outcomes, diagnostic information, and clinical characteristics. Physician-reported outcomes such as nonadherence and information about treatment and management strategies will also be recorded. CONCLUSIONS: This is the first global attempt to generate an ISAR using a common set of core variables to ensure that data collected across all participating countries are standardized.

RESUMO

In this study we described a case of lipofibromatous hamartoma involving the median nerve. We adopted diffusion tensor imaging and constrained spherical deconvolution-based tractography to reconstruct the affected median nerve. Moreover, we extracted diffusion-based parameters reflecting axonal integrity loss of median nerve fibres. Our data showed that constrained spherical deconvolution-based tractography outperformed the diffusion tensor imaging-based method, allowing the detection of the entire median nerve, including its branches, thus offering a robust method to investigate the involvement of the median nerve in pathological conditions. All clinical and technical implications are extensively described.

RESUMO

Chronic obstructive pulmonary disease (COPD), a complex progressive disease, is currently the third leading cause of death worldwide. One recommended treatment option is fixed-dose combination therapy of an inhaled corticosteroid (ICS)/long-acting ß-agonist. Clinical trials suggest pressurized metered-dose inhalers (pMDIs) and dry powder inhalers (DPIs) show similar efficacy and safety profiles in COPD. Real-world observational studies have shown that combination therapy has significantly greater odds of achieving asthma control when delivered via pMDIs. Our aim was to compare effectiveness, in terms of moderate/severe COPD exacerbations and long-acting muscarinic antagonist (LAMA) prescriptions, for COPD patients initiating fluticasone propionate (FP)/salmeterol xinafoate (SAL) via pMDI versus DPI at two doses of FP (500 and 1,000 µg/d) using a real-life, historical matched cohort study. COPD patients with ≥2 years continuous practice data, ≥2 prescriptions for FP/SAL via pMDI/DPI, and no prescription for ICS were selected from the Optimum Patient Care Research Database. Patients were matched 1:1. Rate of moderate/severe COPD exacerbations and odds of LAMA prescription were analyzed using conditional Poisson and logistic regression, respectively. Of 472 patients on 500 µg/d, we observed fewer moderate/severe exacerbations in patients using pMDI (99 [42%]) versus DPI (115 [49%]) (adjusted rate ratio: 0.71; 95% confidence interval: 0.54, 0.93), an important result since the pMDI is not licensed for COPD in the UK, USA, or China. At 1,000 µg/d, we observed lower LAMA prescription for pMDI (adjusted odds ratio: 0.71; 95% confidence interval: 0.55, 0.91), but no difference in exacerbation rates, potentially due to higher dose of ICS overcoming low lung delivery from the DPI.

RESUMO

OBJECTIVE: Asthma has a substantial impact on quality of life and health care resources. The identification of a more cost-effective, yet equally efficacious, treatment could positively influence the economic burden of this disease. Fluticasone propionate/Formoterol (FP/FOR) may be as effective as Fluticasone Salmeterol (FP/SAL). We evaluated non-inferiority of asthma control in terms of the proportion of patients free from exacerbations, and conducted a cost impact analysis. METHODS: This historical, matched cohort database study evaluated two treatment groups in the Optimum Patient Care Research Database in the UK: 1) an FP/FOR cohort of patients initiating treatment with FP/FOR or changing from FP/SAL to FP/FOR and; 2) an FP/SAL cohort comprising patients initiating, or remaining on FP/SAL pMDI combination therapy. The main outcome evaluated non-inferiority of effectiveness (defined as prevention of severe exacerbations, lower limit of the 95% confidence interval (CI) of the mean difference between groups in patient proportions with no exacerbations is -3.5% or higher) in patients treated with FP/FOR versus FP/SAL. RESULTS: After matching 1:3, we studied a total of 2472 patients: 618 in the FP/FOR cohort (174 patients initiated on FP/FOR and 444 patients changed to FP/FOR) and 1854 in the FP/SAL cohort (522 patients initiated FP/SAL and 1332 continued FP/SAL). The percentage of patients prescribed FP/FOR met non-inferiority as the adjusted mean difference in proportion of no severe exacerbations (95%CI) was 0.008 (-0.032, 0.047) between the two cohorts. No other significant differences were observed except acute respiratory event rates, which were lower for patients prescribed FP/FOR (rate ratio [RR] 0.82, 95% CI 0.71, 0.94). CONCLUSIONS: Changing to, or initiating FP/FOR combination therapy, is associated with a non-inferior proportion of patients who are severe exacerbation-free at a lower average annual cost compared with continuing or initiating treatment with FP/SAL.

RESUMO

AIM: The aim of this study is to clearly define the vascularisation of the lateral paratibial septum of the leg, defining the basis for a vertical pedicled adipofascial flap harvested from the anterolateral aspect of the leg to cover pretibial soft tissue defects. MATERIALS AND METHODS: Twelve cadaver legs (eight fixed with formalin and four fresh) were dissected. The vessels running into the lateral paratibial septum were identified. The number of vessels were noted and evaluated at the lateral border of the proximal, middle and distal thirds of the leg. In addition, an angiographic study was performed on two limbs to confirm the connection between tibialis anterior artery and the overlaying fascia through these septal vessels. RESULTS: All the specimens had periosteo-septal vessels running in the lateral aspect of the tibia. The average number was 6.6. The distribution was constant in all the thirds of the leg. CONCLUSION: These data are useful to propose the harvesting technique for adipofascial flap with vertical pedicle as a suitable reconstructive option to cover pretibial soft tissue defects.

RESUMO

Deep second-degree burns are characterized by delayed formation of granulation tissue and impaired angiogenesis. Erythropoietin (EPO) is able to stimulate angiogenesis and mitosis, activating vascularization and cell cycle. The aim of our study was to investigate whether two biosimilar recombinant human erythropoietins, EPO-α and EPO-Z, may promote these processes in an experimental model of burn injury. A total of 84 mice were used and a scald burn was produced on the back after shaving, in 80°C water for 10 seconds. Mice were then randomized to receive EPO-α (400 units/kg/day/sc) or EPO-Z (400 units/kg/day/sc) or their vehicle (100 µL/day/sc 0.9% NaCl solution). After 12 days, both EPO-α and EPO-Z increased VEGF protein expression. EPO-α caused an increased cyclin D1/CDK6 and cyclin E/CDK2 expression compared with vehicle and EPO-Z (p<0.001). Our study showed that EPO-α and EPO-Z accelerated wound closure and angiogenesis; however EPO-α resulted more effectively in achieving complete skin regeneration. Our data suggest that EPO-α and EPO-Z are not biosimilars for the wound healing effects. The higher efficacy of EPO-α might be likely due to its different conformational structure leading to a more efficient cell proliferation and skin remodelling.

RESUMO

In regenerative medicine, new approaches are required for the creation of tissue substitutes, and the interplay between different research areas, such as tissue engineering, microsurgery and gene therapy, is mandatory. In this article, we report a modification of a published model of tissue engineering, based on an arterio-venous loop enveloped in a cross-linked collagen-glycosaminoglycan template, which acts as an isolated chamber for angiogenesis and new tissue formation. In order to foster tissue formation within the chamber, which entails on the development of new vessels, we wondered whether we might combine tissue engineering with a gene therapy approach. Based on the well-described tropism of adeno-associated viral vectors for post-mitotic tissues, a muscular flap was harvested from the pectineus muscle, inserted into the chamber and transduced by either AAV vector encoding human VEGF165 or AAV vector expressing the reporter gene ß-galactosidase, as a control. Histological analysis of the specimens showed that muscle transduction by AAV vector encoding human VEGF165 resulted in enhanced tissue formation, with a significant increase in the number of arterioles within the chamber in comparison with the previously published model. Pectineus muscular flap, transduced by adeno-associated viral vectors, acted as a source of the proangiogenic factor vascular endothelial growth factor, thus inducing a consistent enhancement of vessel growth into the newly formed tissue within the chamber. In conclusion, our present findings combine three different research fields such as microsurgery, tissue engineering and gene therapy, suggesting and showing the feasibility of a mixed approach for regenerative medicine.

RESUMO

BACKGROUND: The most important adverse effect of BoNT-A is the systemic diffusion of the toxin. There is some evidence that the administration of high doses can increase the risk of systemic diffusion and the development of clinically evident adverse effects, however an international consensus does not exist about its maximum dose. AIM: The aim of this study was to evaluate changes in autonomic heart drive induced by high doses (higher than 600 units) of incobotulinumtoxinA injection in spastic stroke patients. Moreover, the treatment safety by monitoring adverse events occurrence was assessed. DESIGN: Case control study. POPULATION: Eleven stroke survivors with spastic hemiplegia. METHODS: Patients were treated with intramuscular focal injections of IncobotulinumtoxinA (NT 201; Xeomin®, Merz Pharmaceuticals GmbH, Frankfurt, Germany). Doses were below 12 units/Kg. Each patient underwent an ECG recording before injection and 10 days after treatment. Linear and non-linear Heart Rate variability (HRV) measures were derived from ECGs with a dedicated software. RESULTS: None of the variable considered showed statistically significant changes after BoNT-A injection. CONCLUSION: The use of incobotulinumtoxinA in adult patients at doses up to 12 units/kg seems to be safe regarding autonomic heart drive. CLINICAL REHABILITATION IMPACT: The use of IncobotulinumtoxinA up to 600 units could be a safe therapeutic option in spastic hemiplegic stroke survivors.

RESUMO

OBJECTIVE: The Authors point out the interest of differential diagnosis and conservative surgical treatment of a rare case of digital and ulnar side of the hand gigantism, with massive fatty infiltration of soft tissues and a neurovascular bundle, to be included into Macrodystrophia Lipomatosa with fibrolipomatous hamartomata. PATIENTS AND METHODS: Excision of the mass included 4th ray disarticulation (the fifth had been amputated several years ago) as well as microsurgical external and internal neurolysis of the ulnar nerve, the ulnar neurovascular bundle being exposed and covered with dermal substitute INTEGRATM, with a good result both from a cosmetic and functional point of view at three year follow up. RESULTS: This is the first report of INTEGRATM covering of a neurovascular bundle. Samples taken from the dermal substitute matrix interface at day 6 and day 25 were examined with transmission Electron Microscopy: a newly formed tissue, rich in precursor cells, was detected. CONCLUSIONS: Conservative surgery, requiring particular microsurgical skills and use of dermal templates, plays an outstanding role in treatment of these rare but aggressive soft tissues masses of the upper limb.

RESUMO

Craniofacial duplication is a very rare malformation. The phenotype comprises a wide spectrum, ranging from partial duplication of few facial structures to complete dicephalus. We report the case of a newborn with an accessory oral cavity associated to duplication of the tongue and the mandible diagnosed by multi-row detector Computed Tomography, few days after her birth. Our case of partial craniofacial duplication can be considered as Type II of Gorlin classification or as an intermediate form between Type I and Type II of Sun classification. Our experience demonstrates that CT scan, using appropriate reconstruction algorithms, permits a detailed evaluation of the different structures in an anatomical region. Multi-row CT scan is also the more accurate diagnostic procedure for the pre-surgical evaluation of craniofacial malformations.
