RESUMO

A hiperplasia hemimandibular é responsável por prejuízos estéticos, funcionais, motores e psicossociais. Com etiologia incerta, ocorre frente ao desequilíbrio de fatores regulatórios de crescimento presentes na camada cartilaginosa do côndilo. O relato objetiva descrever a tomada de decisões baseada em exames complementares específicos aliados à adequada intervenção cirúrgica da lesão. Paciente gênero feminino, 33 anos de idade, compareceu à clínica particular com queixa principal de "face assimétrica", foi requerido uma avaliação cintilográfica objetivando e confirmando a interrupção do crescimento condilar, descartando a hipótese de Osteocondroma e condilectomia. Após preparo ortodôntico prévio, os exames tomográficos foram utilizados na criação de um protótipo que foi impresso após a realização dos movimentos ósseos planejados. Mediante à reconstrução, foi concluído que a assimetria presente não seria totalmente corrigida somente através da intervenção ortognática, sendo necessária também uma osteotomia removendo parte da base do corpo e ângulo mandibular, através da confecção de um guia de corte, promovendo à reanatomização sem a necessidade de acesso extra oral submandibular, evitando uma cicatriz em face feminina. Paciente encontra-se em pós-operatório de 60 meses, sem queixas e satisfeita. Portanto, é evidenciado cada vez mais a influência positiva que o planejamento virtual pode trazer aos profissionais na otimização dos resultados cirúrgicos.


Hemimandibular hyperplasia is responsible for aesthetic, functional, motor, and psychosocial impairments. With an uncertain etiology, it occurs due to the imbalance of regulatory growth factors present in the cartilaginous layer of the condyle. The report aims to describe decision-making based on specific complementary exams combined with the appropriate surgical intervention for the condition. A 33-year-old female patient presented at a private clinic with the main complaint of "asymmetric face." A scintigraphic evaluation was requested to objectively confirm the interruption of condylar growth, ruling out the hypothesis of Osteochondroma and condylectomy. After prior orthodontic preparation, tomographic exams were used to create a prototype that was printed after planned bone movements. Through the reconstruction, it was concluded that the existing asymmetry would not be entirely corrected through orthognathic intervention alone, necessitating also an osteotomy to remove part of the base of the body and mandibular angle. This was done through the creation of a cutting guide, allowing for reanatomization without the need for submandibular extraoral access, thus avoiding a scar on the female face. The patient is 60 months postoperative, with no complaints and satisfied. Therefore, the increasingly positive influence of virtual planning on optimizing surgical outcomes for professionals is evident.

RESUMO

Intravascular papillary endothelial hyperplasia (IPEH) represents an uncommon reactive endothelial hyperplastic proliferation. A 46-year-old man experienced increased volume in the right maxilla, elevation of the nasal ala, and swelling of the hard palate with a reddish hue for 3 months. Computed tomography revealed an expansive hypodense region and cortical bone destruction associated with an impacted supernumerary tooth and an endodontically treated tooth. Under the differential diagnoses of a radicular cyst, dentigerous cyst, and ameloblastoma, an exploratory aspiration and incisional biopsy were performed. This revealed the formation of blood vessels of various diameters lined by endothelium, forming intravascular papillae positive for CD-34. The definitive diagnosis was IPEH, and the patient was treated by embolization and surgery. Histological analysis confirmed the presence of IPEH associated with an odontogenic cyst. After 12 months of follow-up, no recurrence was observed. Also, we reviewed case reports of IPEH affecting the maxilla and mandible. Fourteen intraosseous cases were reported in the maxilla and mandible, with a preference for males and affecting a wide age range. Complete surgical excision was the treatment of choice, and recurrences were not reported. The pathogenesis of IPEH is controversial and may originate from trauma or inflammatory processes. To the best of our knowledge, this is the first report of an association of IPEH with an odontogenic cyst. The importance of IPEH in the differential diagnosis of intraosseous lesions in the jaws is emphasized, and preoperative semiotic maneuvers are needed to prevent surgical complications.

RESUMO

Menetrier's disease represents a low prevalence clinical entity, characterized by complexity in its diagnosis, particularly due to the need to exclude its potential association with gastric cancer. In this context, we present the clinical case of a 54-year-old male with nonspecific gastrointestinal symptoms and hypoalbuminemia. During the upper endoscopy procedure, a noticeable thickening of gastric folds was observed, associated with multiple polypoid lesions in the stomach, predominantly in the fundus and body. Since the patient did not show improvement in symptoms and given the inability to rule out gastric cancer, total gastrectomy was chosen as the treatment. Surgical specimen and histology confirmed the presence of Menetrier's disease.

RESUMO

La hematoma amigdalino espontáneo, es un cuadro clínico raro con baja incidencia a nivel mundial, resultado de un proceso inflamatorio local secundario a la amigdalitis, donde el factor de riesgo más significativo es la amigdalitis a repetición. Desde el punto de vista clínico, su distinción del absceso periamigdalino, puede ser un desafío, lo cual es crucial debido a diferencias en el tratamiento y el pronóstico entre ambas. Al ser un cuadro de baja prevalencia es importante tener un alto nivel de sospecha diagnóstica para abordar adecuadamente esta entidad clínica y prevenir consecuencias potencialmente mortales.


Spontaneous tonsillar hematoma is a rare clinical condition with low incidence worldwide, resulting from a local inflammatory process secondary to tonsillitis, where the most significant risk factor is recurrent tonsillitis. From a clinical standpoint, its distinction from a peritonsillar abscess can be challenging, which is crucial due to differences in treatment and prognosis between the two. Given its low prevalence, maintaining a high level of diagnostic suspicion is important to address this clinical entity and prevent potentially life-threatening consequences appropriately.

RESUMO

Different cellular mechanisms influence steatotic liver disease (SLD) progression. The influence of different levels of steatogenic inputs has not been studied in hepatocytes and hepatic stellate cells (HSCs). METHODS: HepG2 hepatocytes and LX-2 HSCs were cultured in mild (MS) and severe (SS) steatogenic conditions. TGF-ß stimulation was also tested for HSCs in control (T) and steatogenic conditions (MS-T and SS-T). Steatosis was stained with Oil Red, and the proliferation was assayed via WST-8 reduction, apoptosis via flow cytometry, and senescence via SA-ß-galactosidase activity. RESULTS: Regarding hepatocytes, steatosis progressively increased; proliferation was lower in MS and SS; and the viability of both conditions significantly decreased at 72 h. Apoptosis increased in MS at 72 h, while it decreased in SS. Senescence increased in MS and diminished in SS. Regarding HSCs, the SS and SS-T groups showed no proliferation, and the viability was reduced in MS at 72 h and in SS and SS-T. The LX-2 cells showed increased apoptosis in SS and SS-T at 24 h, and in MS and MS-T at 72 h. Senescence decreased in MS, SS, and SS-T. CONCLUSIONS: Lipid overload induces differential effects depending on the cell type, the steatogenic input level, and the exposure time. Hepatocytes are resilient to mild steatosis but susceptible to high lipotoxicity. HSCs are sensitive to lipid overload, undergoing apoptosis and lowering senescence and proliferation. Collectively, these data may help explain the development of steatosis and fibrosis in SLD.

RESUMO

Combined allergic rhinitis and asthma syndrome (CARAS) is an airway-type 2 immune response with a profuse inflammatory process widely affecting the world population. Due to the compromise of quality of life and the lack of specific pharmacotherapy, the search for new molecules becomes relevant. This study aimed to evaluate the effectiveness of the Morita-Bailys-Hillman adduct (CISACN) treatment in the CARAS experimental model. Female BALB/c mice were ovalbumin (OVA) -sensitized and -challenged and treated with CISACN. The treatment decreased the eosinophil migration to the nasal and lung cavities and tissues and the goblet cell hyperplasia/hypertrophy, attenuated airway hyperactivity by reducing the hyperplasia/hypertrophy of the smooth muscle and the extracellular matrix's thickness. Also, the treatment reduced the clinical signs of rhinitis as nasal rubbing and sneezing in a histamine-induced nasal hyperreactivity assay. The immunomodulatory effect of CISACN was by reducing OVA-specific IgE serum level, and IL-33, IL-4, IL-13, and TGF-ß production, dependent on IFN-γ increase. Furthermore, the effect of CISACN on lung granulocytes was by decreasing the p-p38MAPK/p65NF-κB signaling pathway. Indeed, CISACN reduced the p38MAPK and p65NF-κB activation. These data demonstrated the anti-inflammatory and immunomodulatory effects of the CISACN with scientific support to become a pharmacological tool to treat airway inflammatory diseases.

RESUMO

In this study, we evaluated the toxicological and antiproliferative effects of B. glabra Choisy bract extract (BGCE) in its free and loaded into liposomes forms administered to C. elegans mutants with let-60 gain-of-function (gf). Our results demonstrated that the concentration up to 75 µg CAE/mL of BGCE was safe for the worms. Notably, we developed BGCE-loaded liposomes to extend the pharmacological window up to 100 µg CAE/mL without toxicity. In addition, the extract and liposomes reduced the number and area of the multivulva formed in let-60 gf mutants. There was also an increase in the apoptotic signaling in the germline cells and increased longevity mediated through DAF-16 nuclear translocation with GST-4 activation in the treated animals. Our findings demonstrated that the BGCE-loaded liposomes possess antitumoral effects due to the activation of the apoptotic signaling and DAF-16 nuclear translocation.

RESUMO

Hoof diseases are a major welfare and economic issue in the global dairy cattle production industry, which can be minimized through improved management and breeding practices. Optimal genetic improvement of hoof health could benefit from a deep understanding of the genetic background and biological underpinning of indicators of hoof health. Therefore, the primary objectives of this study were to perform genome-wide association studies, using imputed high-density genetic markers data from North American Holstein cattle, for 8 hoof-related traits: digital dermatitis, sole ulcer, sole hemorrhage, white line lesion, heel horn erosion, interdigital dermatitis, interdigital hyperplasia, and toe ulcer, and a hoof health index. De-regressed estimated breeding values from 25,580 Holstein animals were used as pseudo-phenotypes for the association analyses. The genomic quality control, genotype phasing, and genotype imputation were performed using the PLINK (version 1.9), Eagle (version 2.4.1), and Minimac4 software, respectively. The functional genomic analyses were performed using the GALLO R package and the DAVID platform. We identified 22, 34, 14, 22, 28, 33, 24, 43, and 15 significant markers for digital dermatitis, heel horn erosion, interdigital dermatitis, interdigital hyperplasia, sole hemorrhage, sole ulcer, toe ulcer, white line lesion disease, and the hoof health index, respectively. The significant markers were located across all autosomes, except BTA10, BTA12, BTA20, BTA26, BTA27, and BTA28. Moreover, the genomic regions identified overlap with various previously reported quantitative trait loci for exterior, health, meat and carcass, milk, production, and reproduction traits. The enrichment analyses identified 44 significant gene ontology terms. These enriched genomic regions harbor various candidate genes previously associated with bone development, metabolism, and infectious and immunological diseases. These findings indicate that hoof health traits are highly polygenic and influenced by a wide range of biological processes.

RESUMO

OBJECTIVES: Lower urinary tract symptoms due to benign prostatic hyperplasia in men increase with aging. Risks related to anesthesia and surgery have led a search for alternative treatments. Bipolar radiofrequency (RF) thermotherapy is one of the methods adopted in patients with high surgical risks. The aim of this study is to compare the effect of bipolar RF thermotherapy and transurethral resection of the prostate (TURP) methods on voiding symptoms and on post-operative complication rates especially in patients carrying high surgical risks. METHODS: Pre-operative, post-operative 1st and 6th month International Prostate Symptom Score (IPSS), Qmax, quality of life, prostate volumes, and postoperative complications of the patients underwent TURP and RF for benign prostatic hyperplasia (BPH) were compared. RESULTS: In the RF group, the pre-operative median IPSS was 30, prostate volume 41.5 cc, post-void residual (PVR) 80 ml, and Qmax is 5.85 ml/s.; In the TURP group, these were 29, 40 cc, 85 ml, and 5.3 ml/sec, respectively. In the Bipolar RF group, post-operative 1st- and 6th-month median values were IPSS 18, 21; prostate volume 40, 40; PVR 40, 35; Qmax 10.9, 9.15 and in the TURP group IPSS 9, 8; prostate volume 20, 20; PVR 30, 10; Qmax 17.25, 19.1, respectively. CONCLUSION: Bipolar RF thermotherapy is an applicable treatment method for BPH patients with high surgical risks.
