ABSTRACT
RESUMEN El propósito del estudio fue describir las características del síndrome inflamatorio multisistémico asociado a COVID-19 (SIM-C) en los primeros tres años de pandemia en niños de un hospital pediátrico del Perú. Se realizó un estudio observacional, descriptivo con datos de 73 pacientes y se describieron las características clínicas, laboratoriales, tratamiento y complicaciones según la ola de la pandemia y si tuvieron shock. La mediana de edad fue 6 años, las manifestaciones gastrointestinales y mucocutáneas fueron frecuentes en las tres olas. El fenotipo similar a enfermedad de Kawasaki se presentó en 34 (46,6%) pacientes y 21 (28,8%) pacientes desarrollaron shock. El tratamiento más usado fue la inmunoglobulina (95,9%), ácido acetil salicílico (94,5%) y corticoide (86,3%). Cinco (7%) pacientes tuvieron aneurisma coronario y 17 (23,3%) ingresaron a la unidad de cuidados intensivos (UCI). Los pacientes con shock tuvieron mayor alteración laboratorial y necesidad de ventilación mecánica. En conclusión, el SIM-C ha disminuido en los primeros tres años de pandemia posiblemente por la vacunación de COVID-19 en niños.
ABSTRACT This study aimed to describe the characteristics of multisystemic inflammatory syndrome associated with COVID-19 (MIS-C) in the first three years of the pandemic in children in a pediatric hospital in Peru. We conducted an observational, descriptive study with data from 73 patients and described the clinical and laboratory characteristics, treatment and complications according to the wave of the pandemic and whether they had shock. The median age was 6 years, gastrointestinal and mucocutaneous manifestations were frequent in the three waves. Kawasaki disease-like phenotype was present in 34 (46.6%) patients and 21 (28.8%) patients developed shock. The most commonly used treatment was immunoglobulin (95.9%), followed by acetylsalicylic acid (94.5%) and corticosteroid (86.3%). Five (7%) patients had coronary aneurysm and 17 (23.3%) were admitted to the intensive care unit (ICU). Patients with shock had greater laboratorial alteration and need for mechanical ventilation. In conclusion, MIS-C has decreased in the first three years of the pandemic, possibly due to COVID-19 vaccination in children.

ABSTRACT Objectives. To determine the requirement and time to mechanical ventilation and Intensive Care Unit (ICU), hospitalization and hospitalization time, death and disability of the axonal variants of Guillain-Barré Syndrome (GBS) in comparison with the acute demyelinating variant in patients of all the ages. Materials and methods. The systematic review that included patients with GBS. The exposure variable was the axonal variants and the comparator was acute inflammatory demyelinating polyneuropathy (AIDP). The outcomes were the requirement and time on mechanical ventilation (MV), requirement and time in the ICU, hospitalization time, disability and death. The NewCasttle-Ottawa Scale (NOS) was used to assess risk of bias. A meta-analysis was conducted to calculate mean differences and relative risks (RR) with their 95% confidence intervals (CI) using inverse variances and random effects models. Results. Of the 3116 articles found, 46 met the selection criteria. The time on MV was 7.42 days (95% CI: 0.36 to 1.48) and the hospitalization time was 3.11 (95% CI: 0.73 to 5.49) days for the axonal variants. The axonal variants had a RR of 0.47 (95% CI: 0.24 to 0.92) for the requirement of MV in adults, but it was 1.68 (95% CI: 1.25 to 2.25) in children. There was a high statistical heterogeneity. Conclusions. Axonal variants showed, on average, longer MV and hospitalization time, overall and by subgroups. A high MV requirement was found for axonal variants in children; it was lower for adults.
ABSTRACT
Abstract Background Molecularly targeted therapies, such as monoclonal antibodies (mAbs) and Janus Kinase inhibitors (JAKis), have emerged as essential tools in the treatment of dermatological diseases. These therapies modulate the immune system through specific signaling pathways, providing effective alternatives to traditional systemic immunosuppressive agents. This review aims to provide an updated summary of targeted immune therapies for inflammatory skin diseases, considering their pathophysiology, efficacy, dosage, and safety profiles. Methods The review followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. A systematic search was conducted on PubMed over the past 10 years, focusing on randomized clinical trials, case reports, and case series related to targeted immune therapies in dermatology. Eligibility criteria were applied, and data were extracted from each study, including citation data, study design, and results. Results We identified 1360 non-duplicate articles with the initial search strategy. Title and abstract review excluded 1150, while a full-text review excluded an additional 50 articles. The review included 143 studies published between 2012 and 2022, highlighting 39 drugs currently under investigation or in use for managing inflammatory skin diseases. Study limitations The heterogeneity of summarized information limits this review. Some recommendations originated from data from clinical trials, while others relied on retrospective analyses and small case series. Recommendations will likely be updated as new results emerge. Conclusion Targeted therapies have revolutionized the treatment of chronic skin diseases, offering new options for patients unresponsive to standard treatments. Paradoxical reactions are rarely observed. Further studies are needed to fully understand the mechanisms and nature of these therapies. Overall, targeted immune therapies in dermatology represent a promising development, significantly improving the quality of life for patients with chronic inflammatory skin diseases.
ABSTRACT
Focal myositis is a rare disease, and to date, 250 cases have been reported in literature. It is a benign dysimmune disease of unknown etiology. It is defined as myopathy affecting a single muscle without systemic manifestation with a historically proven inflammatory myositis process. It usually presents as a mass ranging from 1 to 20 centimeters, growing insidiously over weeks to months, and may be painless or tender. Or the growth can be rapid and with a lot of pain and disability. It's common in lower limbs and rare in facial muscles. It usually regresses spontaneously and does not invade the surrounding structures. In 18% of cases, there may be a relapse. Laboratory studies may show elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). Creatine kinase (CK) is usually not elevated significantly. Autoantigens are often normal or may be marginally elevated. Magnetic resonance imaging (MRI) is a diagnostic tool of choice and is done with relative ease. Electromyography (EMG) occasionally shows recordable spontaneous and repetitive discharges. Nerve conduction velocity (NCV) may be helpful if nerves are involved. A muscle biopsy usually confirms the diagnosis with specific features. Tumours of muscle and Inflammatory myositis need to be differentiated. Sometimes focal myositis may be associated with immune-mediated inflammatory disease (IMID), neoplasms, radiculopathy, and trauma. Focal myositis is usually self-limiting and benign. It usually responds to NSAID and occasionally may require a short course of steroids, especially in those with elevated ESR and CRP.
ABSTRACT
Background: Historestorative feature is a vital component that any organ can acquire secondary to its damage. Most of the time damage arises from traumatic injury or toxification by toxic agents. In the current context the aortic intima lumen significantly histologically changed secondary to administration of Warbugia ugandensis thus increasing blood supply to vital organs. Methods: Posttest only true experimental study design was used with 33 male New Zeeland rabbits considered for this study. In grouping of animals, Systematic sampling method was used to assign them as control and experimental groups. W. ugandensis extract was obtained after which phytochemical analysis and acute oral toxicity were conducted to determine safe dose. The animals were fed on high fat diet to induce atherosclerosis. Results: The mean fraction of restorative group reduced significantly (p=0.0001) relative to vehicle control group. There was no significant difference in mean area fraction of W. ugandensis restorative group when compared with negative control group (p=1.000). On histological features, restorative group had a smaller lesion as compared to vehicle group. The lipid core was smaller in size with large fibrous cap around it. The endothelial cells surrounded the lesion as opposed to vehicle control group make it more stable. Conclusions: Therefore, it can be concluded that W. ugandensis has historestorative benefits portrayed by reduction of atherosclerotic lesion with a lipid core covered by a large fibrous cap.
ABSTRACT
Leaves of Croton stipulaceuswere extracted (EHex, ECHCl3and EEtOH extracts) to assesstheir antioxidant potential, anti-inflammatory activity in murine models and acute toxicity. EEtOH showed the highest effect in DPPH (37.80% inhibition), FRAP (1065.00 ± 55.30 µmolFe2+) and total polyphenols (231.24 ± 9.05 meq AG/gM). EHex was the most active, ~ 50% inhibition of TPA-induced ear edema; while EEtOH (dose of 2 mg/ear) showed the highest inhibition in the chronic model (97% inhibition), and inhibited MPO activity (48%). In carrageenan-induced edema, ECHCl3(dose 500 mg/kg) was the most active. None of the extracts showed acute toxicity (LD50) at 2 g/kg (p.o.). This work is the first report that supports the traditional use of C. stipulaceusas an anti-inflammatory.
De las hojas de Croton stipulaceusse obtuvieron diferentes extractos (EHex, ECHCl3y EEtOH) evaluando el potencial antioxidante y la actividad antiinflamatoria en modelos murinos y la toxicidad aguda. El EEtOH mostró mayor efecto en DPPH (37.80% inhibición), FRAP (1065.00 ± 55.30 µmolFe2+) y polifenolestotales (231.24 ± 9.05 meq AG/gM). El EHex fue el más activo, cercano al 50% de inhibición del edema auricular inducido con TPA; mientras que el EEtOH (dosis de 2 mg/oreja) mostró la mayor inhibición en el modelo crónico (97% inhibición), e inhibió la actividad de la MPO (48%). En el edema inducido con carragenina, el ECHCl3(dosis 500 mg/kg) fue el más activo. Ninguno de los extractos mostró una toxicidad aguda (DL50) mayor a 2 g/kg (p.o). Este trabajo es el primer reporte que sustenta el uso tradicional de C. stipulaceuscomo antiinflamatorio.

A systemic inflammatory disease known as rheumatoid arthritis (RA) is distinguished by excessive cardiovascular disease (CVD) morbidity and death. Traditional CV risk factors may partially contribute to CV disease in RA. Shared inflammatory mediators, post-translational modifications of peptides/proteins and subsequent immune responses, changes in the composition and function of lipoproteins, increased oxidative stress, and endothelial dysfunction are some of the mechanisms that link RA and CVD. The detailed pathogenetic pathway by which this association between RA and CVD might be explained is still not entirely known. It is crucial for controlling cardiovascular risk in people with RA. Optimizing care of traditional risk factors in addition to those inherent to RA is necessary to lessen the burden caused by CVD. The potential effect of planned Cardiac risk management in these individuals is highlighted by findings for under diagnosis and inadequate treatment of conventional CVD risk factors in RA. Present cardiovascular standards suggest RA patients to be examined for and treated for CVD risk factors without appropriate treatment goals. Utilizing potent anti-rheumatic medications that can reduce disease activity and treating the conventional CV risk factors should both be part of the therapy of CV risk in RA. There is currently insufficient scientific data to develop therapy targets for RA-related CVD risk factors. Thus, more study is required on the traditional CVD risk factor screening and management in RA patients.
ABSTRACT
Inflammatory pseudotumor (IPT) is a benign non-neoplastic rare mass lesion clinically and radiologically simulating neoplasm thus generally requiring a biopsy to exclude malignancy. It occurs almost anywhere all over the body with most common locations being lungs and orbit with only 15% of it occurs in head and neck non-orbital region. Here we are describing a case of 52-year-old female patient having bleeding from left nostril with swelling, redness of left side of nose and face, initially painless. Radiological imaging was highly suspicious of malignancy. HPE showed inflammatory lesions. The fungal culture report of nasal specimen was showing ‘no growth’. Blood examination was within normal limits; blood sugar levels was within normal limits. Systemic steroids were started which showed drastic improvements. Most of the IPTs in head and neck region shows a benign course, but cases related to paranasal sinuses seems to be of highly aggressive behaviour, with poor response to surgery, chemotherapy, radiotherapy; showing recurrences and fatal outcome. In such cases corticosteroid therapy generally shows good outcome. Tumors for which complete resection would result in morbidity may be treated with corticosteroids conservatively and close follow up. Understanding of natural history and pathophysiologic features of IPTs is helpful in differential diagnosis and may prevent unnecessary surgeries.
ABSTRACT
Prostatic tumours are usually benign. Malignant tumours are usually adenocarcinoma. Rare benign prostate tumours include inflammatory myofibroblastic tumours, which can be found in various body parts and are frequently identified in the lung or abdominal cavity of children and young adults. Inflammatory myofibroblastic tumours of the urinary tract present more often in kidneys. Prostatic inflammatory myofibroblastic tumours are sporadic and rare. Presenting 44 years old male with complaints of gross hematuria for 15 days with recurrent urine retention. Per rectal examination revealed, grade II prostate enlargement was firm in consistency. PSA was mildly raised (4.4 ng/ml). Ultrasound abdomen showed enlarged prostate (volume -40 cc) with irregular margins and heterogeneous echo texture showing increased flow on colour Doppler. Transrectal ultrasound (TRUS) showed a well-defined irregular heterogeneously echoic mass in the transitional zone, but TRUS biopsy showed no malignancy. After TURP, prostate chip examination showed inflammatory myofibroblastic pseudotumour of the prostate. Di?erentiation of inflammatory myofibroblastic prostate tumours from malignant tumours through imaging and laboratory tests is di?cult. A case of prostatic inflammatory myofibroblastic tumour observed after transurethral resection of the prostate to treat prostate hyperplasia in a 44-year-old man is presented in this report.
ABSTRACT
El 25% de los pacientes con Enfermedades Inflamatorias Intestinales (EII) se diagnostican antes de los 20 años. En la mayor parte de los centros del país se lleva a cabo la "transferencia" del paciente desde un centro de atención pediátrico a uno de adultos. La "transición" es un criterio de calidad con beneficios en el control de la EII reduciendo el número de recaídas, de hospitalizaciones y de cirugías. Por tal motivo hemos desarrollado un Programa Interdisciplinario de Transición entre dos hospitales de referencia nacional e internacional en EII. Materiales y métodos: Entre 1/2021 y 12/ 2022 se incorporaron 24 pacientes que ingresaron en 3 fases: Fase 1 Pacientes entre 14 y 16 años asistidos en el Hospital Garrahan (HG) con un abordaje interdisciplinario. Fase 2. A partir de los 17 años se realizaron 2 (dos) encuentros en el HG en conjunto con gastroenterólogos de adultos evaluando adherencia y autonomía y la Fase 3 llevada a cabo en el Hospital B. Udaondo (HBU) sólo con el equipo de adultos luego de 6 meses de realizada la transferencia evaluando adherencia al tratamiento, consultas a emergencias, internación y/o cirugías Resultados: Al inicio del Programa el 66% de los pacientes presentaban una actividad moderada a severa vs el 8% al finalizar la fase 3. Luego de la transferencia el 12,5% necesito ingreso a guardia e internación y un 8% tratamiento quirúrgico. El 83% de los pacientes continúan en seguimiento luego de 6 meses de haber sido transferidos (AU)
Twenty-five percent of patients with inflammatory bowel diseases (IBD) are diagnosed before the age of 20 years. In most centers in the country, the "transfer" of the patient from a pediatric to an adult care center is done. However, "transition" is a quality criterion with benefits in the control of IBD by reducing the number of relapses, hospitalizations, and surgeries. For this reason, we developed an Interdisciplinary Transition Program between two national and international reference hospitals in IBD. Materials and Methods: Between January 2021 and December 2022, we incorporated 24 patients into a three-phase program. Phase 1 involved patients between 14 and 16 years of age seen at Garrahan Hospital (HG) with an interdisciplinary approach. Phase 2 began from 17 years of age, with two meetings held at HG involving adult gastroenterologists to evaluate adherence and autonomy. Phase 3 was conducted at Hospital B. Udaondo (HBU) only with the adult team, six months after the transfer, evaluating adherence to treatment, emergency consultations, hospitalizations, and/or surgeries. Results: At the beginning of the program, 66% of the patients presented with moderate to severe disease activity, compared to 8% at the end of Phase 3. After the transfer, 12.5% of the patients required emergency department visits and hospitalization, and 8% required surgical treatment. Eighty-three percent of the patients continue in the program and are still being followed up six months after the transfer (AU)

Abstract Introduction : Chia and flax seeds are rich in alpha-linolenic acid (ALA), which is bioconverted into the active derivatives eicosapentaenoic (EPA) and doco sahexaenoic (DHA) having multiple beneficial effects. However, there is limited knowledge about the anti-inflammatory effects of chia and flax integral flours diets rich in ALA. Objective : The study aimed to evaluate the anti-inflammatory effect of dietary supplementation with integral chia and flax flours in a murine model of LPS-induced systemic inflammation. Methods : Balb/c mice were distributed into three groups: diet A (control), diet B (supplemented with inte gral chia flour), and diet C (supplemented with integral flax flour). Nutritional, hematological, and biochemical determinations were performed. ALA, EPA, and DHA were assessed by GC-MS in the liver, brain, cardiac and skeletal muscles. NF-kB immunoassays were per formed in kidney, liver, and peritoneal macrophages, respectively. The phagocytic capacity was determined in peritoneal macrophages and the expression of the pro- and anti-inflammatory cytokines was assessed by RT-qPCR in the kidney, liver, and spleen. Results : Diets B and C exhibited optimal nutritional adequacy and caused increased levels of ALA, EPA, and DHA in critical tissues compared to the control. The phagocytic capacity of murine peritoneal macrophages (p< 0.01) and IL-10 transcription increased, whereas the expression of NF-κB, IL-1β, IL-6, and TNF-α decreased in animals fed both experimental diets. Conclusions : This work contributes to the current knowledge of the anti-inflammatory effects of chia and flax integral flours rich in ALA and reinforces the health advantages of their consumption.

ABSTRACT
Resumen La enfermedad inflamatoria intestinal de inicio muy temprano (VEOIBD) es una entidad rara en pediatría. Es conocida su asociación con inmunodeficiencias prima rias de origen monogénico. Presentamos el caso de una paciente con diagnóstico de VEOIBD a quien se le realizó una secuenciación masiva del exoma. El resultado del estudio permitió identificar una variante patogénica en el proto oncogen RET, asociada con enfermedad neoplasia endocrina múltiple tipo 2A. No hay reportes de asociación de variantes en el proto oncogen RET con VEOIBD. No se puede adjudicar la presencia de estas dos entidades clínicas a una única causa genética.
Abstract Very early onset inflammatory bowel disease (VEOI BD) is a rare entity in pediatrics. Its association with pri mary immunodeficiencies of monogenic origin is known. We present the case of a patient diagnosed with VEOIBD who underwent massive paralleled exome sequencing. The result of the study showed a pathogenic variant in the RET proto-oncogene, associated with multiple endo crine neoplasia type 2A disease. There are no previous reports of association of RET proto-oncogene variants with VEOIBD. The presence of these two clinical entities cannot be attributed to a single genetic cause.
ABSTRACT
Inflammatory fibroid polyps (IFP), also known as Vanek tumours, are one of the rarest groups of gastrointestinal tract polyps. They represent 0.1-3.0% of all polyps in this organ system. Most common location is the stomach, mainly the antrum (70%), ileum (19%), and colon (6%). Large polyps of the stomach can cause intermittent obstruction, described as 揵all valve syndrome�. This case report, reported in SMS medical college Jaipur in one year six months old child. We report a case of a 1 year 6 months female child with complaint of abdominal lump noted since 7 days, due to this reduced oral intake. On examination single, around 5�cm size non-tender lump is situated in left hypogastric region. On CECT abdomen shows mesenteric origin, may be desmoid tumour, Castleman disease, mesenteric haemangioma or inflammatory myo-fibroblastic tumour. Further MRI abdomen suggestive of inflammatory myo-fibroblastic tumour or NHL. Tumour marker study shows serum ferritin and LDH level raised. On exploration revealed a single, 6 cm lobulated jejunal mass encircle the jejunum, for this resection and anastomosis done. On histopathological report, suggestive of inflammatory fibroid polyp. Patient discharged successfully on 6th pod without any complication. Exploration done and a mass, which encircle the jejunum found. Resection and anastomosis done and patient discharged on 6th pod without any complications. Such an occurrence was incidental in the reported case, which can confuse our diagnosis, so knowledge about this type of disease is very important, especially in paediatrics population.
ABSTRACT
Chlamydia comprises the largest proportion of all sexually transmitted infections (STIs) worldwide. It is caused by Chlamydia trachomatis, an obligate intracellular bacterium and exists in two stages; an extracellular elementary body which is an infectious state and an intracellular reticulate body, a dormant state. The elementary body increases the risk of transfer of chlamydial infection during oral, genital or anal sex. On the other hand, the vegetative state of the reticulate body promotes the chance of latent and recurrent infection. In 2020, WHO estimated 129 million new chlamydia infections. Most of the chlamydial infections are asymptomatic (85-90%) which promotes transfer between partners. If untreated, it can lead to an ascending infection which greatly impacts sexual and reproductive health. In addition, it can infect the baby around childbirth and may result in stillbirth or neonatal death. The immuno-pathogenesis of the chlamydial infection is predominantly evoked by major outer membrane protein (MOMP), a dominant chlamydial antigen on the cell wall; along with the chlamydial antigen, heat shock protein 60 (HSP60) triggers host immune responses. The innate and adaptive immune responses result in extensive fibrosis and permanent damage to the fallopian tube resulting in tubal factor infertility and ectopic tubal pregnancy. The improved strategies in screening, diagnosis, treatment and follow up of Chlamydial infection can have noticeable effects on prevention of incidence, retarding the progression and avoiding recurrence of infection leading to a reduction in the global burden of STIs and the consequent adverse neonatal outcome.
ABSTRACT
Background of the Study: The response of the body to harmful stimuli, such as tissue damage or a pathogenic infection is known as inflammation. Rauwofia vomitera is a medicinal plant that is native to large areas of tropical Africa and it belongs to the family of Apocynaceae. It is a medicinal herb used in traditional Nigerian medicine to treat a variety of diseases, including inflammatory disorders.Aim of the Study:The present study investigated the anti-inflammatory effects of methanol extract of Rauwofia vomitera leaves (MERVL) using in-vivo based assays. Methodology: The anti-inflammatory effect of (MERVL) was ascertained using the Egg albumin -induced inflammation using in vivo assay. A total of thirty (30) adult male albino rats (130-170g) were divided into five (5) groups of six (6) rats each for the in-vivo anti-inflammatory assay. Group 1 normal; Group 2 was given 10 mg/kg body weight of Indomethacin and Groups 3, 4 and 5 were given 100, 200 and 400 mg/kg body weight of MERVL) respectively. Acute toxicity was carried out using standard method.Place and Duration of the Study: Department of Pharmacology Lab, Enugu State of University of Science and Technology Agbani Nigeria, between March 2021 and August 2021.Results: The percentage yield of the extract was 10.8%. The result of the quantitative and qualitative phytochemical screening of methanol extract of R. vomitoria leaves showed that Phenol (1590 � 55.66) Flavonoid (1168 � 11.43) and Tannin (1466 � 40.73) were present in high concentration whereas, Alkaloid (549 � 4.21) Glycoside (315 � 61.38) and Terpenoid (162 � 1.38) were present in moderate concentration. Saponin (1.16 � 0.23) and Steroid (0.84 � 0.03) were present in low concentrations. Acute toxicity tests showed no toxicity and mortality at doses up to 5000 mgkg-1. A significant (P < 0.05) reduction in the mean paw oedema was observed for all the treatment groups from 1 hour to 12 hours when compared to the normal group. The result shown that groups treated with 100, 200 and 400 mg/kg b.w of extract inhibit the inflammation in a non-dose dependent manner with percentage mobilization of 5.7%, 14.1% and 6.2% respectively.Conclusion: The study's results demonstrate that MERVL exhibits remarkable anti-inflammatory and anti-oxidant activities and the extract yielded a better reduction in edema and increases mobilization in leukocyte in response to agar suspension. It also demonstrates that MERVL has a modulatory effect on the vascular changes that accompany inflammation. The plant's anti-inflammatory properties could potentially result from the interaction of different photochemical substances present. The findings suggest that, if used, the plant may serve as a source of anti-inflammatory agents.
ABSTRACT
O objetivo do presente estudo foi revisar a literatura para buscar evidências na associação entre a doença de Alzheimer e a Periodontite. A metodologia usada resultou numa busca às bases de dados PubMed/MEDLINE, Cochrane Library e Web of Science, através dos artigos publicados entre o período de maio de 2000 a maio de 2022. A doença de Alzheimer (DA) é classificada como uma condição neurodegenerativa, um grupo heterogêneo de doenças caracterizadas pela perda lenta e progressiva de uma ou mais funções do sistema nervoso. A doença periodontal (DP) é uma doença infecciosa e inflamatória que causa principalmente destruição óssea alveolar e perda dentária e estima-se que entre 20 e 50% da população geral possa sofrer de DP, dos quais 15-20% apresentam formas graves. A inflamação desempenha um papel crítico no aparecimento e progressão de ambas as doenças. A conclusão desta revisão é que a literatura estudada mostra que os patógenos periodontais e as citocinas pró-inflamatórias contribuíram para a progressão do processo neurodegenerativo da doença de Alzheimer. Porém, são necessários mais estudos clínicos controlados randomizados para a confirmação da relação causal desta associação.
The aim of this study was to review the literature to look for evidence in the association between Alzheimer's disease and Periodontitis. The methodology used resulted in a search of the PubMed/MEDLINE, Cochrane Library and Web of Science databases, through the articles published between May 2000 and May 2022. Alzheimer's disease (AD) is classified as a neurodegenerative condition, a heterogeneous group of diseases characterized by the slow and progressive loss of one or more functions of the nervous system. Periodontal disease (PD) is an infectious and inflammatory disease that mainly causes alveolar bone destruction and tooth loss and it is estimated that between 20 and 50% of the general population may suffer from PD, of which 15-20% present severe forms. Inflammation plays a critical role in the onset and progression of both diseases. The conclusion of this review is that the literature studied shows that periodontal pathogens and pro-inflammatory cytokines contributed to the progression of the neurodegenerative process of Alzheimer's disease. However, more randomized controlled clinical trials are needed to confirm the causal relationship of this association.

Background: Aim of the study was to scientifically validate the traditional Indian claims of Curcuma longa's (turmeric) antinociceptive (pain-relieving) and anti-inflammatory effects. Methods: The alcoholic extract of C. longa was tested in three rodent nociceptive models: acetic acid-induced writhing: examines visceral pain, formalin test: evaluates both acute and chronic neurogenic and inflammatory pain and tail immersion test to assess thermal pain. The extract's effects were compared to a control group and morphine (reference drug). Results: C. longa extract significantly reduced abdominal constrictions in the acetic acid test (59.36% inhibition). In the formalin test, the extract significantly decreased paw licking response time in both early (54.12% inhibition) and late phases (78.59% inhibition). C. longa extract significantly increased the tail flick reaction time in the immersion test, indicating pain relief. Conclusions: This study confirms the antinociceptive and anti-inflammatory activities of C. longa, providing scientific evidence for its traditional use in pain management.
ABSTRACT
Herbal remedies with medicinal properties have been utilized in Asian countries for centuries. Recently, Pancratium triflorum Roxb., also known as the forest spider lily, has captured the attention of researchers due to its potential therapeutic benefits. This plant produces white flowers and contains several important phytochemicals, including Lycorine, citrate, Gallic acid, Ellagic acid, Quercetin, and Kaempferol. Molecular docking, a computer simulation technique, has been used to identify potential drug candidates that can bind effectively to the active site of a protein. This study explored the anti-inflammatory and anticancer properties of Pancratium triflorum Roxb.'s Phyto-constituents using molecular docking with Auto dock 4.2.6. The study focused on the Vioxx-bound human Cox2 receptor and the Tyrosine kinase receptor bound to Gliteritinib. Standard ligands were used for redocking, and the Swiss ADME software was employed for bioavailability prediction to validate the findings. The results showed that Lycorine and Crinine have excellent anti-inflammatory properties, while Kaempferol and Quercetin have promising anticancer properties. Further research is necessary, but these findings suggest that Pancratium triflorum Roxb. could be a valuable addition to the medical world. However, further research is required to validate these findings, and in vivo studies are needed to confirm the efficacy and safety of these phytochemicals as potential drug candidates.
ABSTRACT
Rheumatoid arthritis is a sign of progressive degradation of cartilage, subchondral bone, and small joints, as well as the persistence of synovitis and the formation of pannus. This research intends to assess the purported anti-arthritic effects of an extract from the seeds of Portulaca oleracea. Female Wistar albino rats (140–200 g) were used and assigned to five groups: Group I administrated NS (10 ml/kg), Group II received 0.2 ml of CoII-IFA, Group III received 300 mg/kg of fish oil, and Groups IV & V administrated 100 and 200 mg/kg of methanolic extract of Portulaca oleracea (MePO). During the experiment, the rats' weight, arthritic score, and footpad oedema were evaluated to determine the severity of their arthritis. Later, blood samples were collected from the animals, which were then analysed for haematological, pro-inflammatory, antioxidant, and histological parameters. A dose-dependent reduction was seen in rats treated with a methanolic extract of Portulaca seeds. Levels of haematological and pro-inflammatory cytokines were considerably reduced by treatment. Although both the standard drug and 200 mg/kg of MePO had anti-inflammatory effects, the latter's were more pronounced at this dose. When looking at the two side by side, results showed that the treatment groups of RBC, WBC, NL-ratio, and ML-ratio levels were normalised. Further histology confirmed the reduction of joint deformity, oedema, formation of pannus, and infiltration of neutrophils in the MePO groups in contrast to arthritic rats. It is hypothesised that Portulaca oleracea may reduce the arthritis and can be used as an adjuvant therapy or incorporate it into your diet with the main course of treatment.
ABSTRACT
The key assessment of the study was evaluating the gastro-protective properties of Barleria buxifolia root extract (REBB) in ulcerative rats. The roots of Barleria buxifolia have properties like antioxidant, anti-inflammatory, and other health benefits. Induction of gastric ulcers was done with aspirin (150 mg/kg, b.w., p.o) for 3 days and was accompanied by treatment with REBB (200 & 400 mg/kg orally) for 15 days. Ranitidine (20 mg/kg, orally) was received as the standard treatment for 14 days. Ulcer index, percent inhibition of ulceration, lipid peroxidation (LPO), TNF-? levels, and histopathological examination of the gastric mucosa were measured. Aspirin-induced stomach ulcers were seen in 100% of the groups, whereas other animal groups, aside from the control group possessed relatively comparable inductions. Ulcer number, ulcer index (p<0.01), and LPO (p<0.05) shown significant reduction in the 400mg/kg and Ranitidine (20mg/kg) when compared to Aspirin induced control group. Whereas the Ulcer score (p<0.001) and TNF-? (p<0.05) showed significant reduction in Ranitidine treated group but showed objectively improvement but statistically non-significant results in 200mg/kg and 400mg/kg REBB. Hence it was found that Baleria buxifolia root extract effectively mitigates aspirin-induced gastric ulceration in rats, underscoring its potential as a gastro protective agent.
