Multidisciplinary Approach in Rare, Fulminant-Progressing, and Life-Threatening Facial Necrotizing Fasciitis

(1) Background: Necrotizing fasciitis is known as a severe condition with a high risk of mortality, placing it among the most feared infections. In most cases, it has a polymicrobial etiology (type 1), requiring complex treatment that is continuously adapted to the evolving microbiological status. The facial localization of the disease is rare, fulminant progressing, and is often life-threatening. (2) Methods: We present the case of a patient with multiple comorbidities who, following trauma to the nasal dorsum, developed a wound with a rapid and severe progression to extensive bilateral periorbital necrosis. This was accompanied by a dramatic deterioration in their general condition, a polymicrobial biological status, and fluctuating progression despite instituted treatment (both medical and surgical). (3) Results: The patient required multiple surgical interventions by multidisciplinary teams (plastic surgery; ear, nose, and throat specialist (ENT); maxillofacial surgery; and ophthalmology), experiencing periods of a severe, life-threatening general condition, necessitating prolonged orotracheal intubation. Wounds with fluctuating progression, extensive skin necrosis, and significant post-excisional soft tissue defects required skin graft coverage. The result meant a saved life and functional and aesthetic sequelae at the level of the face. (4) Conclusions: Necrotizing fasciitis of the face is a rare and severe disease that must be recognized early and treated appropriately by a multidisciplinary team to save the patient’s life and minimize the resulting functional and aesthetic sequelae.

Open Trauma to the Larynx by a Stab Wound: A Case Report

<i>Introduction</i>: Open laryngeal trauma is rare. Only early and appropriate diagnosis and treatment can preserve or restore the respiratory and phonatory functions of the larynx and prevent the appearance of disabling functional sequelae. <i>Material and method</i>: This was a 50-year-old patient with a history of psychiatric illness, admitted for treatment of a penetrating wound to the neck following an attempted self-lysis with a bladed weapon (knife). On examination, we objectified a conscious patient with a makeshift bandage soiled with blood at the neck. A respiratory murmur was also perceived. Given this picture, the patient was immediately taken in a lying position to the operating room for surgical management. The postoperative course was marked on D13 by a decannulation process and a complete decanution on D15 postoperatively. We proceeded to remove the nasogastric tube on D21. A cure without respiratory or vocal sequelae was obtained on D28 postoperatively. <i>Conclusion</i>: Open trauma is a diagnostic and therapeutic emergency. If unrecognized or poorly managed, it can be life-threatening in the immediate term or cause serious long-term after-effects.

Reduction Cranioplasty in Cases of Hydrocephalic Macrocephaly: Pearls and Pitfalls of Computer-Assisted Surgery.

Reduction cranioplasty may be indicated to address functional or cosmetic sequelae of hydrocephalic macrocephaly. With the advent of CAD/CAM digital workflow, surgeons can design and fabricate craniotomy guides, templates, and models that allow for precise cranial reconstruction. Although there are several advantages of virtual planning, pre-determined surgical plans may limit intraoperative flexibility, requiring surgeons to troubleshoot errors in pre-operative planning or model design. The purpose of this report is to present a series of cases demonstrating our institution's technique for single-stage reduction cranioplasty using a CAD/CAM workflow. This report will highlight the benefits and challenges associated with a contemporary digital workflow for reduction cranioplasty.

Insights into Long COVID: Unraveling Risk Factors, Clinical Features, Radiological Findings, Functional Sequelae and Correlations: A Retrospective Cohort Study

BackgroundThe long-term symptomatology of COVID-19 has yet to be comprehensively described. The aim of the study was to describe persistent COVID-19 symptoms in a cohort of hospitalized and home-isolated patients. MethodsA retrospective cohort study was conducted on long COVID patients. Long COVID symptoms were identified, and patients were divided into hospitalized (in-patients) and home-isolated (out-patients) as well as according to the number of symptoms. Patients were examined by a multydisciplinary medical team. Blood tests, high resolution chest computed tomography (CT), physical and infectious examination were performed. Finally, in-patients were evaluated at two time-points: on hospital admission (T0) and after three months from discharge (Tpost). ResultsThree hundred and sixty-four COVID-19 patients were enrolled. 82% of patients reported at least one or more symptoms. The most reported symptom was fatigue. Chest CT showed alteration in 76% of patients and pulmonary function alterations were observed in 44.7% of patients.A higher risk of presenting at least one symptom was seen in patients treated with corticosteroid and a higher risk of presenting chest CT residual lesion was observed in hospitalized patients and in patients that received hydroxychloroquine treatment. Moreover, a higher risk of altered pulmonary function was observed in older patients. ConclusionLong-term sequelae are present in a remarkable number of long COVID patients and pose a new challenge to the healthcare system to identify long-lasting effects and improve patients’ wellbeing. Multi-disciplinary teams are crucial to develop preventive measures, and clinical management strategies.

Snakebites by venomous snakes in Brazilian serpentaria and zoos over a 10-year period (2012–2021)

Despite the wide range of institutions that maintain venomous snakes in captivity in Brazil there are no comprehensive data on the occurrence of snakebites and envenomations in these places. We examined the range of native and exotic species of venomous snakes kept by Brazilian zoos and serpentaria (scientific and commercial) and assessed the frequency of snakebites in workers handling these snakes during a 10-year period (2012–2021). Twenty-two (73.3%) of 30 institutions returned a standard questionnaire, including 15 serpentaria and 7 zoos that together kept 10,607 venomous snakes in 2022/2023. Commercial and scientific serpentaria had many more snakes (n = 10,550, consisting of 10,499 native specimens and 51 exotic specimens) than zoos (n = 57 native specimens), with two genera accounting for the majority of native species (Bothrops spp. = 84.5% and Crotalus durissus ssp. = 13.5%). Thirty-seven snakebites were reported and involved primarily the hands (33), seven of which occurred during venom extraction and 30 in other circumstances, most of them while handling/manipulating the cages or snake boxes (10) and restraining (9) or feeding (5) the snake. In addition, there were two cases of venom accidently sprayed on the face, including the eyes. Most bites were caused by Bothrops spp. (31), followed by C. durissus ssp. (4), Lachesis muta (1) and Micrurus corallinus (1). Thirty-three bites (89.2%) were treated with antivenom, with four bites to the fingers by Bothrops spp. resulting in local functional sequelae. There were 366,918 venom extractions with a ratio of 1.9 bites/100,000 extractions; no bites were recorded in the six institutions that sedated the snakes prior to venom extraction, which accounted for 22.7% of all extractions. These findings show that although snakebites are rare in Brazilian zoos and serpentaria, severe envenomation may occur. The occurrence of snakebites could be reduced by measures such as sedation of the snakes before venom extraction.

Traumatic Intracranial Intrusion of the Mandibular Condyle in the Middle Fossa: A Rare Case Report

AbstractThe displacement of the condyle into the middle cranial fossa after a high kinetic trauma represents a rare and low prevalence situation in the clinical routine of the maxillofacial surgeon. After a motorcycle accident, a 19-year-old male patient evolves with displacement of the left mandibular condyle to the middle cranial fossa, requiring surgical management in association with the neurosurgical team for repositioning and reconstruction of the glenoid fossa. After craniotomy, the condyle was visualized in the middle fossa. After bone disimpaction with a driller, the condyle was repositioned and the glenoid fossa was reconstructed with a titanium mesh. After 12 months of follow-up, no neurological or functional sequela was observed. The displacement of the mandibular condyle to the cranial fossa is rarely reported in the literature. It requires a multidisciplinary team for its management. Long-term follow-up is also necessary, especially in young patients.

Non-invasive prehabilitation to foster widespread fMRI cortical reorganization before brain tumor surgery: lessons from a case series.

The objective of this prospective, single-centre case series was to investigate feasibility, clinical outcomes, and neural correlates of non-invasive Neuromodulation-Induced Cortical Prehabilitation (NICP) before brain tumor surgery. Previous studies have shown that gross total resection is paramount to increase life expectancy but is counterbalanced by the need of preserving critical functional areas. NICP aims at expanding functional margins for extensive tumor resection without functional sequelae. Invasive NICP (intracranial neuromodulation) was effective but characterized by elevated costs and high rate of adverse events. Non-invasive NICP (transcranial neuromodulation) may represent a more feasible alternative. Nonetheless, up to this point, non-invasive NICP has been examined in only two case reports, yielding inconclusive findings. Treatment sessions consisted of non-invasive neuromodulation, to transiently deactivate critical areas adjacent to the lesion, coupled with intensive functional training, to activate alternative nodes within the same functional network. Patients were evaluated pre-NICP, post-NICP, and at follow-up post-surgery. Ten patients performed the intervention. Feasibility criteria were met (retention, adherence, safety, and patient's satisfaction). Clinical outcomes showed overall stability and improvements in motor and executive function from pre- to post-NICP, and at follow-up. Relevant plasticity changes (increase in the distance between tumor and critical area) were observed when the neuromodulation target was guided by functional neuroimaging data. This is the first case series demonstrating feasibility of non-invasive NICP. Neural correlates indicate that neuroimaging-guided target selection may represent a valid strategy to leverage neuroplastic changes before neurosurgery. Further investigations are needed to confirm such preliminary findings.

Functional independence measure, sequelae, and comorbidities in individuals with COVID-19: a cross-sectional study

Objective: to verify whether there is loss of functionality and association between sequelae, comorbidities and between the Functional Independence Measure with sociodemographic data and clinical aspects in individuals affected by COVID-19. Method: this is a cross-sectional, descriptive, exploratory and quantitative study. Participants were contacted by telephone and answered a questionnaire covering sociodemographic and clinical aspects; post-COVID-19 sequelae, presence of comorbidities and Functional Independence Measure Scale. Results: 172 individuals participated with an average age of 41.42±14.21 years, 54.7% were female, 34.9% had comorbidities, 80.2% had post-COVID sequelae, 90.1% did not require hospitalization and 93.6% were vaccinated. The total Functional Independence Measure score was 120.73±11.3, corresponding to complete independence. There was an association between the cognitive domain and female sex (p=0.022) and white individuals (p=0.025), and between the motor domain, age between 18 and 59 years (p=0.014) and not being vaccinated against COVID-19 (p=0.046). Conclusion: comorbidities are associated with post-COVID-19 sequelae. Non-vaccinated individuals, when infected with COVID-19, may present impairment in the motor domain.

Posterior reversible encephalopathy syndrome with functional and motor sequelae: A case report

Posterior Reversible Encephalopathy Syndrome (PRES) is a rare clinicoradiological neurological disorder, initially elucidated in 1996, Since this first description of PRES numerous case reports and case series, as well as retrospective observational studies describing the syndrome have been published. Importantly, no randomized controlled studies have been performed, We present the case of a young patient with no significant medical history who presented with neurological symptoms consistent with Posterior Reversible Encephalopathy Syndrome (PRES). Brain MRI confirmed the diagnosis of Posterior Reversible Encephalopathy Syndrome (PRES). Additionally, the etiological assessment yielded negative results. A notable aspect in our patient's case is the persistence of sequelae, characterized by dexterity and grip impairment on the right side, hindering various activities of daily living. The diagnosis of PRES is both radiological and clinical, with MRI playing a crucial role. Treatment is primarily symptomatic, sometimes requiring intensive care unit admission. Prognosis is favorable in the majority of cases, but severe complications and even death can occur. The reversibility of initial symptoms is well-documented in the literature. Long-term functional impairment outcomes following PRES have not been adequately characterized in the literature. Therefore, it is necessary to conduct follow-up screenings in more patients presenting both typical and atypical PRES syndromes. This will provide insight into whether the functional and motor sequelae of PRES are less reversible.

Medium-Term Disability and Long-Term Functional Impairment Persistence in Survivors of Severe COVID-19 ARDS: Clinical and Physiological Insights

BackgroundAlthough the medium- and long-term sequelae of survivor of acute respiratory distress syndrome (ARDS) of any cause have been documented, little is known about the way in which COVID-19-induced ARDS affects functional disability and exercise components. Our aims were to examine the medium-term disability in severe COVID-19-associated ARDS survivors, delineate pathophysiological changes contributing to their exercise intolerance, and explore its utility in predicting long-term functional impairment persistence. MethodsWe studied 108 consecutive subjects with severe COVID-19 ARDS who remained alive 6 months after intensive care unit (ICU) discharge. Lung morphology was assessed with chest non-contrast CT scans and CT angiography. Functional evaluation included spirometry, plethysmography, muscle strength, and diffusion capacity, with assessment of gas exchange components through diffusing capacity of nitric oxide. Disability was assessed through an incremental exercise test, and measurements were repeated 12 and 24 months later in patients with functional impairments. ResultsAt 6 months after ICU discharge, a notable dissociation between morphological and clinical-functional sequelae was identified. Moderate-severe disability was present in 47% of patients and these subjects had greater limitation of ventilatory mechanics and gas exchange, as well as greater symptomatic perception during exercise and a probable associated cardiac limitation. Female sex, hypothyroidism, reduced membrane diffusion component, lower functional residual capacity, and high-attenuation lung volume were independently associated with the presence of moderate-severe functional disability, which in turn was related to higher frequency and greater intensity of dyspnea and worse quality of life. Out of the 71 patients with reduced lung volumes or diffusion capacity at 6 months post-ICU discharge, only 19 maintained a restrictive disorder associated with gas exchange impairment at 24 months post-discharge. In these patients, 6-month values for diffusion membrane component, maximal oxygen uptake, ventilatory equivalent for CO2, and dead space to tidal volume ratio were identified as independent risk factors for persistence of long-term functional sequelae. ConclusionsLess than half of survivors of COVID-19 ARDS have moderate-severe disability in the medium term, identifying several risk factors. In turn, diffusion membrane component and exercise tolerance at 6-month ICU discharge are independently associated with the persistence of long-term functional sequelae.

Inferior long-term Results of a Prospective Randomized Controlled Trial initially demonstrating enhanced Sensory Nerve Recovery using a Chitosan Nerve Tube.

Traumatic peripheral nerve injuries can result in significant functional impairments and long-term sequelae. This study evaluated the long-term outcomes of a chitosan tube implantation protecting the epineural coaptation after peripheral nerve injuries using two different tube versions (V 1.0 and V 2.0 with different wall thickness and resorption characteristics) compared to a control group. The study focused on pain levels, sensory function, and overall functional outcomes. Patients who received tube implantation around direct coaptation sites of digital nerves were prospectively randomized and compared to control patients without additional tube protection. Pain levels, sensory function, grip force, and functional scores were assessed at different time points, ranging from three months to five years after the procedure. Furthermore, biodegradation of the tubes was measured via high-resolution MR-neurography (MRN) and categorized. Long-term evaluation revealed that patients with V 1.0 had higher pain levels compared to the control group after five years. They also reported more symptoms of numbness and hypersensitivity. V 2.0 patients exhibited higher pain levels at three months, which did not persist at six months. However, they showed compromised sensory function, with higher values of two-point discrimination compared to V 1.0 and the control group. No differences were found in grip force or functional scores between the groups. MRI displayed remnants of implants even in long-term follow-up. The findings suggest potential limitations due to pain increase and impaired sensory function associated with tube implantation in the long term. However, in the short term, the material seemed to have a protective effect (as published previously). The resorption process was not completed at the end of the observation period of five years. This might explain the prolonged scarring and inferior long-term results. Future research should focus on improving tube materials and design to minimize adverse effects and enhance functional outcomes in patients with peripheral nerve injuries.

APPORT DE LA CHIRURGIE PLASTIQUE DANS LES TUMEURS MALIGNES EVOLUEES DES LEVRES

Lip cancers are among the pathologies that are quite common in the practice of plastic surgeons in our country. These tumors in their advanced form provide aesthetic, functional and life-threatening sequelae, which defines their seriousness and the difficulties of management for both oncological excision and reconstruction. The average consultation time was 18 months. The predominant site was located at the level of the lower lip in 53.4%, the macroscopic appearance of the tumors was ulcero-budding in the majority of cases. The repair process was adapted to the location and extent of the defect. Reconstruction involved direct suture in 4.6% of patients, skin grafts in 4.6% of cases, bone graft in 2.3% of cases, locoregional flaps in 72.1%, and bone grafts in 72.1%. remotely in 16.2% of patients.

Long-term outcome of pulmonary involvement in patients with coronavirus disease 2019: The role of high-resolution computed tomography and functional status - A prospective single-center observational study.

Since its first outbreak, coronavirus disease 2019 (COVID-19) has led to a great deal of published literature highlighting the short-term determinants of morbidity and mortality. Recently, several studies have reported radiological and functional sequelae from 3 months to 1 year among hospitalized COVID-19 survivors; however, long-term (more than 1 year) respiratory consequences in this population remain to be evaluated. To assess the long-term radiological and pulmonary function outcomes of patients with COVID-19 2 years after resolution of the initial infection. Hospitalized COVID-19 patients with moderate to severe disease who survived acute illness were included in this prospective and partially retrospective study. Clinical assessment, laboratory tests, high-resolution computed tomography scans, and pulmonary function tests (PFTs) were performed at baseline, followed by radiological and lung function assessments at 6 and 24 months. Among 106 enrolled participants (mean age 62 ± 13.5 years; males: 61), 44 (41.5%) and 27 (25.4%) underwent radiological assessment at 6 and 24 months, respectively. Overall, 22.6% (24) of patients had residual radiological abnormalities. Overt fibrosis was observed in 12.2% of patients. Computed tomography disease severity and extent diminished significantly at 6 (13 ± 6, P < 0.001) and 24 months (11 ± 6, P < 0.001) from baseline. PFTs were performed in 65 (61.3%), 22 (20.7%), and 34 (32%) patients at baseline, 6 and 24 months, respectively. Impaired diffusion capacity (median diffusion capacity for carbon monoxide: 60%, interquartile range [IQR]: 51-80), restrictive lung defect (mean total lung capacity: 73.4% ± 18% predicted), and reduced exercise tolerance (median 6-min walk distance: 360 m, IQR: 210-400) were the predominant features at baseline. With the exception of exercise tolerance, a statistically significant improvement was observed in lung function parameters at the extended follow-up (2 years). Hospitalized COVID-19 survivors are at increased risk of developing long-term pulmonary complications, including lung fibrosis. A protocol-based approach to the management of post-COVID-19 patients is mandatory to improve future outcomes.

Prognostic impact of positive microscopic margins (R1 resection) in patients with GIST (gastrointestinal stromal tumours): Results of a multicenter European study

BackgroundAlthough several prognostic factors in GIST have been well studied such as tumour size, mitotic rate, or localization, the influence of microscopic margins or R1 resection remains controversial. The aim of this study was to evaluate the influence of R1 resection on the prognosis of GIST in a large multicentre retrospective series of patients. MethodsFrom 2001 to 2013, 1413 patients who underwent surgery for any site of GIST were identified from 61 European centers. 1098 patients were included, excluding synchronous metastases, concurrent malignancies, R2 resection or GIST recurrence. Tumour rupture (TR) was reclassified according to the Oslo sarcoma classification. Cox proportional hazards ratio and Kaplan-Meier survival estimates were used to analyse 5-year recurrence-free survival (RFS). ResultsOf 1098 patients, 38 (3%) underwent R1 resection with a risk of TR of 11%. The 5-year RFS was 89.6% with a median follow-up of 81 months [range: 31.2–152 months]. On univariate analysis, lower RFS was significantly associated with R1 resection [HR = 2.13; p = 0.04], high risk score according to the modified NIH classification, administration of adjuvant therapy [HR = 2.24; p < 0.001] and intraoperative complications [HR = 2.82; p < 0.001]. Only intraoperative complications [HR = 1.79; p = 0.02] and high risk according to the modified NIH classification including the updated definition of TR [HR = 3.43; p = 0.04] remained significant on multivariate analysis. ConclusionThis study shows that positive microscopic margins are not an independent predictive factor for RFS in GIST when taking into account the up-dated classification of TR. R1 resection may be considered a reasonable alternative to avoid major functional sequelae and should not lead to reoperation.

Evaluation of academic performance and social integration of children operated for hydrocephalus in Cameroon.

Low intelligence quotient (IQ) and delayed psychomotor development (DPD) are formidable complications of hydrocephalus. The aim of this study was to evaluate the academic performance and social integration of children operated on for hydrocephalus in Cameroon. The authors present a cross-sectional study with retrospective data collection from January 2010 to May 2020. All children less than 10years of age who had undergone surgery for a ventriculo-peritoneal shunt indicated for hydrocephalus with a post-operative evolution of 7 to 10years and who were attending school were included. Academic performance was assessed using the Wechsler Intelligence Scale for Children IV (WISC IV), and social integration was assessed using the Vineland II score. Of the 45 children aged 7 to 10years who attended school and were followed-up, the sex ratio was 1.25 in favor of males. 77.8% of these children had a malformation with paralysis being the most common functional sequela (29%). 73.3% of our patients had good social integration. Fifty-three percent of patients had reduced academic performance, with non-verbal performance being the most frequent (62.2%). Long-term memory was the most impaired, with 73.3% having a very low speed of information processing. Non-verbal performance was the most affected (62.2%) particularly long-term memory. Forty percent had an IQ below 70. The statistically significant determinants of social integration were age, sex, malformative etiology, and good psychomotor development, and the statistically significant determinants of educational delay were age, malformative etiology, IQ below 70, and time to care. Academic performance was reduced in more than half of our patients, but most of them had good social integration. Early diagnosis and management improve the chances of good psychomotor development and IQ.

Surgical Approach to Necrotizing Fasciitis in the Buccal Fat Pad

Cervicofacial necrotizing fasciitis (CNF) of the face is a rare and potentially life-threatening bacterial infection that requires immediate intervention. CNF involving the buccal fat pad particularly demands surgical drainage, with attention to the surrounding anatomical structures to prevent vascular or nerve damage. In this study, we reviewed the anatomy of buccal fat pads to suggest appropriate surgical approaches. A retrospective chart review was conducted on seven patients with CNF who had a buccal fat pad abscess requiring surgical incision and drainage between January 2022 and August 2023. Abscesses within the central buccal fat pad and its pterygoid extensions were drained via intraoral incisions. Abscesses in the temporal extension were addressed by the Dingman approach. All patients underwent our surgical drainage regimen combined with proper intravenous antibiotics, leading to successful treatment of CNF without significant functional sequelae, with an average stay of 18.71 days. The buccal fat pad, which corresponds to the deep space of the face, is surrounded by vital structures such as the facial artery, vein, nerve, and parotid duct. When treating abscesses in the buccal fat pad, it is important to understand the relationship of the fat pad to other vital structures for optimal outcomes.

Epidemiological Profiles of Acute Otitis Media at the Commune II Referral Health Center in the Bamako District

Acute otitis media is a very common condition in children under the age of 7, most of whom suffer their first episode before the first three years of life. Despite scientific advances in its therapeutic and preventive management, this condition remains frequent and cosmopolitan, particularly in otolaryngology (ENT) and pediatric wards. In view of the possibility of disabling complications, we set out to study the epidemiological and clinical profile of this condition for the first time in the ENT department of the Commune II Reference Health Centre in the District of Bamako, Mali. This is a descriptive, retrospective study, using routine consultation data from January to December 2022. Based on exhaustive sampling, we collected 568 cases of confirmed AOM, representing an incidence of 20.63%. Patient age ranged from 3 months to 83 years, with an average of 12.49 years. Overall, the 3-7 age groups predominated, with 30.63% of cases. However, patients under 2 years of age predominate in progressive forms of the various stages. This study shows that AOM is a frequent occurrence in our department, and highlights the need for good interdisciplinary networking between pediatricians and ENT specialists in the management of AOM, in order to avoid possible recurrences and functional sequelae.

Dopamine enhances recovery after traumatic brain injury through ubiquitylation and autophagic degradation of RIPK1

BackgroundAlthough the neurotransmitter dopamine (DA) plays a crucial pathophysiologic role after traumatic brain injury (TBI), its function and specific underlying mechanisms of action remain unclear.MethodsAdult male mice underwent controlled cortical impact (CCI). We administered DA intraperitoneally to mice for 14 consecutive days, starting 8 h before CCI. On day 3 after brain injury, cortical lesion volume and brain water content were measured. On days 7–13, behavioral tests were performed.ResultsHerein we report that DA inhibits neural death after injury, which is mediated via the dopamine D1 receptor (DRD1). Our results also showed that DRD1 signaling promotes RIPK1 ubiquitination via the E3 ubiquitin ligase Chip and then degradation through autophagy. Importantly, in vivo data revealed that DRD1 signaling prevented neural death, suppressed neuroinflammation, and restored many TBI-related functional sequelae.ConclusionsThese data reveal a novel mechanism involving dopamine, and suggest that DRD1 activation positively regulates Chip-mediated ubiquitylation of RIPK1—leading to its autophagic degradation.
