Onco-Ontogeny of Squamous Cell Cancer of the First Pharyngeal Arch Derivatives.

Head and neck squamous cell carcinoma (H&NSCC) is an anatomic, biological, and genetic complex disease. It involves more than 1000 genes implied in its oncogenesis; for this review, we limit our search and description to the genes implied in the onco-ontogeny of the derivates from the first pharyngeal arch during embryo development. They can be grouped as transcription factors and signaling molecules (that act as growth factors that bind to receptors). Finally, we propose the term embryo-oncogenesis to refer to the activation, reactivation, and use of the genes involved in the embryo's development during the oncogenesis or malignant tumor invasion and metastasis events as part of an onco-ontogenic inverse process.

Celecoxib Decreases the Need for Rescue Analgesics after Total Knee Arthroplasty: A Meta-Analysis.

This systematic review and meta-analysis aimed to evaluate the analgesic efficacy and adverse effects of celecoxib after total knee arthroplasty. Keywords in the PubMed and Scopus databases were used to find article abstracts. Each included clinical trial was assessed using the Cochrane Collaboration risk of bias tool, and we extracted data on postoperative pain assessment using the Visual Analogue Scale (VAS) at rest, ambulation, and active range of motion, rescue analgesic intake, and adverse effects. Inverse variance tests with mean differences were used to analyze the numerical variables. The Mantel-Haenszel statistical method and the odds ratio were used to evaluate the dichotomous data. According to this qualitative assessment (n = 482), two studies presented conclusions in favor of celecoxib (n = 187), one showed similar results between celecoxib and the placebo (n = 44), and three clinical trials did not draw conclusions as to the effectiveness of celecoxib versus the placebo (n = 251). Moreover, the evaluation of the rescue analgesic intake showed that the patients receiving celecoxib had a lower intake compared to patients receiving a placebo (n = 278, I2 = 82%, p = 0.006, mean difference = -6.89, 95% IC = -11.76 to -2.02). In conclusion, the pooled analysis shows that administration of celecoxib alone results in a decrease in rescue analgesic consumption compared to a placebo after total knee surgery.

Modulation of myeloid-derived suppressor cell functions by oral inflammatory diseases and important oral pathogens.

The oral cavity presents a diverse microbiota in a dynamic balance with the host. Disruption of the microbial community can promote dysregulation of local immune response which could generate oral diseases. Additionally, alterations in host immune system can result in inflammatory disorders. Different microorganisms have been associated with establishment and progression of the oral diseases. Oral cavity pathogens/diseases can modulate components of the inflammatory response. Myeloid-derived suppressor cells (MDSCs) own immunoregulatory functions and have been involved in different inflammatory conditions such as infectious processes, autoimmune diseases, and cancer. The aim of this review is to provide a comprehensive overview of generation, phenotypes, and biological functions of the MDSCs in oral inflammatory diseases. Also, it is addressed the biological aspects of MDSCs in presence of major oral pathogens. MDSCs have been mainly analyzed in periodontal disease and Sjögren's syndrome and could be involved in the outcome of these diseases. Studies including the participation of MDSCs in other important oral diseases are very scarce. Major oral bacterial and fungal pathogens can modulate expansion, subpopulations, recruitment, metabolism, immunosuppressive activity and osteoclastogenic potential of MDSCs. Moreover, MDSC plasticity is exhibited in presence of oral inflammatory diseases/oral pathogens and appears to be relevant in the disease progression and potentially useful in the searching of possible treatments. Further analyses of MDSCs in oral cavity context could allow to understand the contribution of these cells in the fine-tuned balance between host immune system and microorganism of the oral biofilm, as well as their involvement in the development of oral diseases when this balance is altered.

Dactylopius opuntiae [Cockerell] Could Be a Source of Antioxidants for the Preservation of Beef Patties.

Dactylopius opuntiae is an insect pest that contains at least carminic acid, which has antioxidant properties. Since there is a relationship between the antioxidant ability and preservative action of compounds applied to meat products, the purpose of this study was to evaluate the antioxidant activity and usefulness of a D. opuntiae extract for beef patty preservation. The insects were bred and processed to obtain a liquid extract. For the extract, its carminic acid content, antioxidant activity against two free radicals, and actions on food quality parameters were determined. The D. opuntiae dry powder contained 2.91% w/w carminic acid, while the liquid extract exhibited an IC50 value of 3437.8 ± 67.8 and 19633.0 ± 674.5 µg/mL against the DPPH and ABTS radicals. Nevertheless, these antioxidant actions were lower than those found in a D. coccus extract. The D. opuntiae extract improved in a short time the redness and yellowness, eliminated the unfavorable effect of their vehicle on the MetMb level, and greatly reduced the TBARS formation. For the first time, an extract of D. opuntiae was applied to beef patties, and its beneficial antioxidant action on meat acceptance parameters was confirmed, which has potential commercial applications.

Analgesic Efficacy and Safety of Tapentadol Immediate Release in Bunionectomy: A Meta-Analysis.

The aim of this systematic review and meta-analysis was to evaluate the analgesic effect of different doses of tapentadol immediate release (IR) and its adverse effects after a bunionectomy. Pubmed, Cochrane, Lilacs, Medline, and Imbiomed were used to identify abstracts of scientific publications related to the keywords of this systematic review (PROSPERO ID CRD42023437295). Moreover, the risk of bias in all included articles was assessed using the Cochrane Collaboration risk of bias tool. Data on the sum of pain intensity, total pain relief, global assessment, and adverse effects were extracted. The statistical method of inverse variance with means difference was used to evaluate the numerical data and the Mantel-Haenszel and Odd Ratio test to analyze the dichotomous data. In addition, the number needed to treat, the number needed to harm, and the 95% confidence intervals were calculated. A qualitative evaluation (n = 2381) was carried out according to the conclusions of the authors. Tapentadol (n = 1772) was more effective in relieving postoperative pain than the placebo (n = 609) after a bunionectomy. In addition, the analgesic efficacy of IR tapentadol (n = 1323) versus the placebo (n = 390) was evaluated in a total of 1713 patients using a global evaluation of the treatments. All three doses of IR tapentadol showed better results compared to the placebo after a bunionectomy. Finally, the adverse effects have a direct relationship with the dose, and the greatest number of adverse effects are most observed with tapentadol IR 100 mg (n = 2381). It is concluded that tapentadol IR (100 mg) leads to the best satisfaction score in this meta-analysis.

Artificial Intelligence for Image Analysis in Oral Squamous Cell Carcinoma: A Review.

Head and neck tumor differential diagnosis and prognosis have always been a challenge for oral pathologists due to their similarities and complexity. Artificial intelligence novel applications can function as an auxiliary tool for the objective interpretation of histomorphological digital slides. In this review, we present digital histopathological image analysis applications in oral squamous cell carcinoma. A literature search was performed in PubMed MEDLINE with the following keywords: "artificial intelligence" OR "deep learning" OR "machine learning" AND "oral squamous cell carcinoma". Artificial intelligence has proven to be a helpful tool in histopathological image analysis of tumors and other lesions, even though it is necessary to continue researching in this area, mainly for clinical validation.

Analgesic Efficacy of COX-2 Inhibitors in Periodontal Surgery: A Systematic Review and Meta-Analysis.

The objective of this systematic review and meta-analysis was to evaluate the analgesic efficacy of COX-2 inhibitors versus other drugs in periodontal surgery. Two researchers searched PubMed, Google Scholar, ACM Digital, BASE, EBSCOhost, Scopus, or Web of Science for clinical trials using various combinations of words. All articles that met the selection criteria were assessed using the Cochrane Collaboration's risk of bias tool. For data analysis, the inverse variance and mean difference statistical method was used with Review Manager 5.3 software for Windows. According to the conclusion of each study (qualitative evaluation), only one clinical trial had results in favor of a COX-2 inhibitor when compared to placebo, one clinical study informed that a COX-2 was better that an active control, four studies showed similar analgesic efficacy to active controls, and one clinical study informed the analgesic effect of one celecoxib-caffeine combination in comparison with celecoxib alone and placebo (n = 337). The COX-2 inhibitors showed a decrease in the rescue analgesic consumption (n = 138; I2 = 15%; mean difference = -0.31; 95%CIs = -0.6 to -0.01), and lower pain intensity at four hours (n = 178; I2 = 0%; mean difference = -2.25; 95%CIs = -2.94 to -1.55; p = 0.00001) when compared to active controls after periodontal surgery. In conclusion, the data indicate that COX-2 agents produce better pain relief in comparison to placebo and other drugs after periodontal surgery.

Emerging avenues linking myeloid-derived suppressor cells to periodontal disease.

Periodontal disease is one of the most common inflammatory disorders in humans. Gingivitis is the mildest form of periodontal disease and its progression can lead to periodontitis, an inflammatory disease characterized by soft tissue damage that can lead to progressive destruction of the periodontal ligament and alveolar bone. Diverse populations of immune cells are involved in periodontal disease. Myeloid-derived suppressor cells (MDSCs) represent a heterogeneous group of immature myeloid cells derived from hematopoietic precursor cells and exhibit T cell immunosuppressive functions that are thought to be involved in periodontal disease. Therefore, MDSCs have been recently analyzed in the context of this disease. In this review, we discuss the most recent advances in the characterization of the biological aspects, subpopulations, and traffic of MDSCs, as well as their immunosuppressive and osteoclastogenic activity in the context of periodontal disease and in the presence of key periodontal pathogens.

Concomitant use of allopathic medicine and herbal products for weight-loss among people with overweight or obesity from Central Mexico / Uso concomitante de medicina alopática y productos herbales para bajar de peso en personas con sobrepeso u obesidad del centro de México

This study evaluated the prevalence of concomitant use of herbal products for weight loss (HPWL) and allopathic medicine. Factors associated with the prevalence, adverse reactions, and the alteration of medication adherence with the concomitant use of HPWL alone and in combination with allopathic medicine, were assessed. The study was descriptive and cross-sectional using a questionnaire conducted among people with overweight or obesity (n=662) from five cities of Central Mexico. Adherence to medications was measured using the Morisky Medication Adherence Scale. The prevalence of adverse reactions induced by the concomitant use of HPWL, and allopathic medicine was 25.3%. The use of HPWL affected medication adherence by 68%. There is a high prevalence (45.2%) of concomitant use of HPWL and allopathic medicine in people with overweight or obesity in Central Mexico. The concomitant use of HPWL and allopathic medicine induces adverse reactions, mainly gastrointestinal, and thus, medication adherence is affected.

Self-Reported Periodontal Disease and Its Association with SARS-CoV-2 Infection.

Introduction: Knowledge of the oral manifestations associated with SARS-CoV-2 infection, the new coronavirus causing the COVID-19 pandemic, was hindered due to the restrictions issued to avoid proximity between people and to stop the rapid spread of the disease, which ultimately results in a hyperinflammatory cytokine storm that can cause death. Because periodontal disease is one of the most frequent inflammatory diseases of the oral cavity, various theories have emerged postulating periodontal disease as a risk factor for developing severe complications associated with COVID-19. This motivated various studies to integrate questions related to periodontal status. For the present work, we used a previously validated self-report, which is a useful tool for facilitating epidemiological studies of periodontal disease on a large scale. Methodology: A blinded case-control study with participants matched 1:1 by mean age (37.7 years), sex, tobacco habits and diseases was conducted. After the diagnostic samples for SARS-CoV-2 detection were taken in an ad hoc location at Guadalajara University, the subjects were interviewed using structured questionnaires to gather demographic, epidemiological and COVID-19 symptom information. The self-reported periodontal disease (Self-RPD) questionnaire included six questions, and subjects who met the criteria with a score ≥ 2 were considered to have periodontal disease. Results: In total, 369 participants were recruited, with 117 participants included in each group. After indicating the subjects who had self-reported periodontal disease, a statistically significant difference (p value ≤ 0.001) was observed, showing that self-reported periodontal disease (n = 95, 85.1%) was higher in SARS-CoV-2-positive individuals than in controls (n = 66, 56.4%), with an OR of 3.3 (1.8-6.0) for SARS-CoV-2 infection in people with self-reported periodontal disease. Cases reported a statistically higher median of symptoms (median = 7.0, Q1= 5.5, Q3 = 10.0) than controls (p value ≤ 0.01), and cases with positive self-RPD had a significantly (p value ≤ 0.05) higher number of symptoms (median = 8.0, Q1 = 6.0, Q3 = 10.0) in comparison with those who did negative self-RPD (median = 6.0, Q1 = 5.0, Q3 = 8.0). Conclusions: According to this study, self-reported periodontal disease could be considered a risk factor for SARS-CoV-2 infection, and these individuals present more symptoms.

Roles of microRNAs and Long Non-Coding RNAs Encoded by Parasitic Helminths in Human Carcinogenesis.

Infectious agents such as viruses, bacteria, and parasites can lead to cancer development. Infection with the helminthic parasite Schistosoma haematobium can cause cancer of the urinary bladder in humans, and infection with the parasites Clonorchis sinensis and Opisthorchis viverrini can promote cholangiocarcinoma. These three pathogens have been categorized as "group 1: carcinogenic to humans" by the International Agency for Research on Cancer (IARC). Additionally, the parasite Schistosoma japonicum has been associated with liver and colorectal cancer and classified as "group 2B: possibly carcinogenic to humans". These parasites express regulatory non-coding RNAs as microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), which modulate genic expression in different biological processes. In this review, we discuss the potential roles of miRNAS and lncRNAs encoded by helminthic parasites that are classified by the IARC as carcinogenic and possibly carcinogenic to humans. The miRNAs of these parasites may be involved in carcinogenesis by modulating the biological functions of the pathogen and the host and by altering microenvironments prone to tumor growth. miRNAs were identified in different host fluids. Additionally, some miRNAs showed direct antitumoral effects. Together, these miRNAs show potential for use in future therapeutic and diagnostic applications. LncRNAs have been less studied in these parasites, and their biological effects in the parasite-host interaction are largely unknown.

Efficacy of Methylprednisolone Compared to Other Drugs for Pain, Swelling, and Trismus Control after Third Molar Surgery: A Meta-Analysis.

The purpose of this systematic review and meta-analysis was to assess the efficacy of methylprednisolone compared to other drugs to control postoperative complications following third molar surgery. PubMed and Google Scholar were used for article searching. Thereafter, the trials meeting the selection criteria and with high methodological quality, according to the Cochrane Collaboration's risk of bias tool, were included in this study. The inverse variance test and mean difference using the Review Manager Software 5.3 for Windows were used to carry out data analysis. Qualitative analysis shows that methylprednisolone is more effective than NSAIDs, but inferior to dexamethasone, for controlling postoperative complications after third molar removal. The quantitative analysis showed no statistical difference for pain control, while trismus evaluation showed a statistical difference after 7 postoperative days in favor of methylprednisolone, when compared to other drugs. In conclusion, methylprednisolone was more effective for trismus control compared to other drugs after lower third molar surgery.

Postoperative administration of ketorolac compared to other drugs for pain control after third molar surgery: A meta-analysis of double-blind, randomized, clinical trials.

AIMS: The aim of this study was to evaluate the analgesic effectiveness and adverse reactions of ketorolac in comparison with other drugs when administered postoperatively after third molar surgery. METHODS: PubMed and Google Scholar were utilized to search for articles comparing the efficacy and safety of ketorolac and other analgesic agents after third molar surgery. Data from papers with a lower risk of bias were recorded. The overall evaluation of analgesia onset, general and subgroup evaluation of the number of patients requiring rescue analgesic medication, general and subgroup assessment of the study medication (satisfaction on the study drugs), and the overall estimation of adverse effects were performed using the Review Manager Software 5.3 to analyse the data and obtain the meta-analysis plot. RESULTS: The subgroup evaluation of the study medication showed that patients who received ketorolac 30 mg were more satisfied than those who were given parecoxib 1 mg (odds ratio [OR] = 8.57, 95% confidence interval [CI] = 3.66-20.08, P = .00001), parecoxib 2 mg (OR = 7.17, 95% CI = 2.88-17.86, P = .0001), parecoxib 5 mg (OR = 3.03, 95% CI = 1.69-5.41, P = .0002), and parecoxib 10 mg (OR = 2.42, 95% CI = 1.36-4.32, P = .003). Moreover, patients who received ketorolac reported fewer adverse reactions compared with those who had received opioid analgesics (OR = 0.14, 95% CI = 0.32-1.76, P = .0001). CONCLUSIONS: The data from this study demonstrates that the postoperative administration of ketorolac 30 mg presents better results on patient satisfaction when compared to parecoxib 1 mg to 10 mg, and presents a similar satisfaction to parecoxib 20 mg following third molar removal.

Analgesic effectiveness and safety of celecoxib versus non-opioid active controls after third molar surgery: A meta-analytical evaluation.

The aim of this meta-analysis was to assess the analgesic efficacy and adverse effects of celecoxib compared to non-opioid drugs after third molar surgery. A search in PubMed and Google Scholar was performed to identify clinical trials, and then, the Cochrane Collaboration tool was used to assess the risk of bias for all clinical trials. Studies without any high-risk of bias were included in the statistical analysis. The data extraction included the pain intensity measured by the visual analogue scale (VAS), the number of patients using rescue analgesics and adverse effects of gastric (nausea and vomiting), and nervous (dizziness and headache) systems. Data were analyzed using the Review Manager Software 5.3 for Windows and the Risk Reduction Calculator. The visual analog scale, total pain relief, and the number of patients who needed rescue analgesics showed statistical significance. Moreover, celecoxib had a lower frequency of nausea and vomiting compared with ibuprofen. In conclusion, celecoxib was more effective than acetaminophen and ibuprofen for pain control after third molar surgery.

Analgesic Efficacy of Etoricoxib following Third Molar Surgery: A Meta-analysis.

BACKGROUND: The purpose of this meta-analysis was to assess the clinical efficacy of etoricoxib in comparison with traditional NSAIDs for postoperative pain after third molar surgery. METHODS: The quality of studies found in PubMed and Google Scholar was evaluated with Cochrane Collaboration's risk of bias tool. Data on total consumption of rescue analgesics, number of patients using rescue analgesics, global assessment of study treatments, and adverse effects were extracted exclusively from high-quality clinical trials. Each meta-analysis was performed with the Review Manager Software 5.3 for Windows. RESULTS: The qualitative analysis showed that etoricoxib has better analgesic activity when compared with ibuprofen (2 clinical trials) and diclofenac (1 clinical trial). A similar analgesic efficacy between etoricoxib and nonselective Cox-2 NSAIDs was informed in 3/8 studies (2 compared to ibuprofen and 1 to naproxen sodium). Moreover, the number of patients requiring rescue analgesics in the postoperative period showed a statistical difference in favor of etoricoxib when compared to NSAIDs. CONCLUSION: Etoricoxib significantly reduces the number of patients needing rescue analgesics compared to NSAIDs after third molar surgery.

A Meta-Analysis of the Analgesic Efficacy of Single-Doses of Ibuprofen Compared to Traditional Non-Opioid Analgesics Following Third Molar Surgery.

The purpose of this systematic review was to determine the analgesic efficacy and adverse effects of ibuprofen in comparison with other traditional non-opioid analgesics after third molar surgery. A total of 17 full texts were identified in PubMed and assessed using the Cochrane Collaboration's risk of bias tool by two independent researchers. The sum of pain intensity differences, total pain relief, the overall evaluation, the number of patients requiring rescue analgesics, and adverse effects were collected. Data were analyzed using the Review Manager Software 5.3. for Windows. A total of 15 articles met the criteria. The qualitative and quantitative analysis showed that ibuprofen is more effective to relieve post-operative dental pain than acetaminophen, meclofenamate, aceclofenac, bromfenac, and aspirin. Moreover, ibuprofen and traditional non-steroidal anti-inflammatory drugs have a similar safety profile. In conclusion, ibuprofen 400 mg appears to have good analgesic efficacy and a safety profile similar to other traditional non-steroidal anti-inflammatory drugs after third molar surgery.

In vitro and in vivo anti-inflammatory effects of an ethanol extract from the aerial parts of Eryngium carlinae F. Delaroche (Apiaceae).

ETHNOPHARMACOLOGICAL RELEVANCE: Eryngium carlinae F. Delaroche (Apiaceae) is an herb used in folk medicine as a diuretic, analgesic, and anti-inflammatory agent. AIM OF THE STUDY: This work assessed the diuretic, antinociceptive, and anti-inflammatory actions of an ethanol extract from the leaves and stems of Eryngium carlinae (ECE). These ethnomedicinal properties of ECE were scientifically validated using in vitro and in vivo assays. MATERIALS AND METHODS: The antinociceptive and diuretic actions of ECE (10-200 mg/kg p.o.) were assessed with the acetic acid-induced writhing test and by using metabolic cages to house mice, respectively. The in vitro anti-inflammatory actions of ECE (1-500 µg/ml) were evaluated using LPS-stimulated primary murine macrophages, and the in vivo anti-inflammatory actions were assessed using the TPA-induced ear edema test (2 mg/ear) and carrageenan-induced paw edema test (50-200 mg/kg p.o.). The production of inflammatory mediators was estimated using in vitro and in vivo assays. RESULTS: ECE lacked antinociceptive and diuretic effects. ECE increased the production of IL-10 in LPS-stimulated macrophages (EC50 = 37.8 pg/ml) and the carrageenan-induced paw edema test (ED50 = 82.6 mg/kg). ECE showed similar in vivo anti-inflammatory actions compared to those observed with indomethacin. CONCLUSION: ECE exerts in vitro and in vivo anti-inflammatory effects by increasing the release of IL-10.

Current concepts in ameloblastoma-targeted therapies in B-raf proto-oncogene serine/threonine kinase V600E mutation: Systematic review.

BACKGROUND: Ameloblastomas are common benign epithelial odontogenic neoplasms that present an aggressive and unpredictable behavior that may modify treatment strategies. Different signaling pathways that participate in the progression of these tumors have been identified. B-raf proto-oncogene serine/threonine kinase (BRAF) is a protein involved in the behavior of ameloblastomas, and it is related to many cell mechanisms. BRAF gene mutations have been identified in ameloblastomas, of which the BRAF V600E (valine substituted by glutamic acid at amino acid 600) mutation has been the most common and can be present concomitantly with other mutations that may be involved in its behavior. Targeted therapies have been used as an alternative in the case of resistance or contraindications to conventional treatments. AIM: To document the presence of BRAF V600E and additional mutations, their behavior, and targeted therapies in these tumors. METHODS: An electronic literature search was conducted according to PRISMA guidelines in PubMed/MEDLINE, Cochrane, EMBASE, and SpringerLink using the terms "ameloblastomas", "BRAF V600E", "additional mutations", and "targeted therapies". Ameloblastomas were classified according to WHO guidelines. Inclusion criteria were articles in English, published not more than 10 years ago, and studies with laboratory works related to BRAF V600E. Articles were evaluated by two independent reviewers and retrieved for full-text evaluation. The EBLIP Critical Appraisal Checklist was used to evaluate the quality of the eligible studies. Descriptive statistical analysis was performed. RESULTS: Two independent reviewers, with a substantial concordance indicated by a kappa coefficient of k = 0.76, evaluated a total of 19 articles that were included in this study. The analysis registered 521 conventional ameloblastomas (AM), 81 unicystic ameloblastomas (UA), 13 ameloblastic carcinomas (AC), three metastatic ameloblastomas (MA), and six peripheral ameloblastomas (PA), of which the histopathological type, anatomic location, laboratory tests, expression of BRAF mutation, and additional mutations were registered. The BRAF V600E mutation was found in 297 AM (57%), 63 UA (77.7%), 3 AC (23%), 1 MA (50%), and 5 PA (83.3%). Follicular type predominated with a total of 116 cases (40%), followed by plexiform type with 63 cases (22.1%). Furthermore, both types presented additional mutations, in which alterations in JAK3 P132T, SMARCB1, PIK3CA, CTNNB1, SMO, and BRAF G606E genes were found. Four case reports were found with targeted therapy to BRAF V600E. CONCLUSION: The identification of BRAF V600E and additional mutations as an aid in targeted therapies has been a breakthrough in alternative treatments of ameloblastomas where surgical treatments are contraindicated.

Anti-inflammatory and antinociceptive effects of an ethanol extract from Senna septemtrionalis.

Senna septemtrionalis (Viv.) H.S. Irwin & Barneby (Fabaceae) is a medicinal plant used as a folk remedy for inflammation and pain. The objective of this study was to evaluate the anti-inflammatory and antinociceptive actions of an ethanol extract of Senna septemtrionalis aerial parts (SSE). The in vitro anti-inflammatory effects of SSE were assessed using LPS-stimulated macrophages and the subsequent quantification of the levels of cytokines (IL-6, IL-1ß, and TNF-α) with ELISA kits, nitric oxide (NO), and hydrogen peroxide (H2O2). The in vivo anti-inflammatory actions of SSE were evaluated with the TPA-induced ear oedema test and the carrageenan-induced paw oedema test. The antinociceptive actions of SSE (10-200 mg/kg p.o.) were assessed using three models: two chemical assays (formalin-induced orofacial pain and acetic acid-induced visceral pain) and one thermal assay (hot plate). SSE showed in vitro anti-inflammatory actions with IC50 values calculated as follows: 163.3 µg/ml (IL-6), 154.7 µg/ml (H2O2) and > 200 µg/ml (IL-1ß, TNF-α, and NO). SSE showed also in vivo anti-inflammatory actions in the TPA test (40% of inhibition of ear oedema) and the carrageenan test (ED50 = 137.8 mg/kg p.o.). SSE induced antinociceptive activity in the formalin orofacial pain test (ED50 = 80.1 mg/kg) and the acetic acid-induced writhing test (ED50 = 110 mg/kg). SSE showed no antinociceptive actions in the hot plate assay. The pre-treatment with glibenclamide abolished the antinociceptive action shown by SSE alone. Overall, SSE exerted in vitro and in vivo anti-inflammatory actions, and in vivo antinociceptive effects by the possible involvement of ATP-sensitive K + channels.

Partial traumatic amputation of an upper limb with excellent functional recovery: A 13-year follow-up clinical case.

Introducción: Se han publicados pocos informes sobre el seguimiento a largo plazo de la reparación quirúrgica de una amputación parcial. Algunos estudios de largo plazo han registrado tasas similares de discapacidad entre los pacientes con amputaciones y los sometidos a operación reconstructiva. Objetivo: Informar un caso clínico de una amputación traumática parcial de una extremidad superior con recuperación funcional después de 13 años de seguimiento. Caso clínico: Paciente masculino de ocho años con traumatismo grave en la extremidad superior izquierda, desprendimiento de los músculos bíceps y tríceps y una fractura diafisaria oblicua del húmero distal. La fractura se fijó de manera transitoria con alambres de Kirschner de 2.0 mm, seguido de inmovilización con aparato de Sarmiento y al final se realizó reducción abierta y fijación interna con placa de compresión dinámica de 3.5 mm. La integridad muscular y neurovascular permitió la reparación microquirúrgica del nervio radial y la rehabilitación neuromuscular. Conclusiones: Este informe clínico representa un caso de una recuperación funcional excelente atestiguada a través de un periodo de seguimiento de 13 años.

Introduction: There are just a few reports that deal with long-term outcomes of a partial amputation surgical repair. Long-term studies have reported similar rates of disability among patients with amputations and those that have been undergoing reconstructive surgery. Objective: The purpose of this report is describing a clinical case of a patient with partial traumatic amputation of an upper limb with an excellent functional recovery after 13 years of follow-up. Clinical case: The case of an 8 year old male patient with severe trauma to the upper left limb is described. The lesions included an oblique diaphyseal open fracture of the distal region of the humerus, along with detachment of the biceps and triceps muscles. The fracture was fixed transiently with 2.0 mm Kirschner's wire followed by immobilization with Sarmiento's brace, and finally, open reduction and internal fixation with a 3.5 mm dynamic compression plate were performed. The muscular and neurovascular integrity allowed microsurgical repair of the radial nerve and neuromuscular rehabilitation. Conclusion: This clinical report represents a case with an excellent functional recovery witnessed through a 13-year follow-up period.
