Thigh lift surgery is generally performed in patients with severe weight loss outcomes, particularly those undergoing bariatric surgery. However, there are other congenital malformation conditions that may require the same treatment, such as Beckwith Wideman syndrome.

The human gut is a complex ecosystem that supports billions of living species, including bacteria, viruses, archaea, phages, fungi, and unicellular eukaryotes. Bacteria give genes and enzymes for microbial and host-produced compounds, establishing a symbiotic link between the external environment and the host at both the gut and systemic levels. The gut microbiome, which is primarily made up of commensal bacteria, is critical for maintaining the healthy host’s immune system, aiding digestion, synthesizing essential nutrients, and protecting against pathogenic bacteria, as well as influencing endocrine, neural, humoral, and immunological functions and metabolic pathways. Qualitative, quantitative, and/or topographic shifts can alter the gut microbiome, resulting in dysbiosis and microbial dysfunction, which can contribute to a variety of noncommunicable illnesses, including hypertension, cardiovascular disease, obesity, diabetes, inflammatory bowel disease, cancer, and irritable bowel syndrome. While most evidence to date is observational and does not establish direct causation, ongoing clinical trials and advanced genomic techniques are steadily enhancing our understanding of these intricate interactions. This review will explore key aspects of the relationship between gut microbiota, eubiosis, and dysbiosis in human health and disease, highlighting emerging strategies for microbiome engineering as potential therapeutic approaches for various conditions.

ObjectiveInflammation has been associated with an increased risk for cancer development, while innate immune system activation could counteract the risk for malignancies. Familial Mediterranean fever (FMF) is a severe systemic inflammatory condition and also represents the archetype of innate immunity deregulation. Therefore, the aim of this study is to investigate the risk for cancer development in FMF.MethodsThe risk ratio (RR) for malignancies was separately compared between FMF patients and fibromyalgia subjects, Still’s disease patients and Behçet’s disease patients. Clinical variables associated with cancer development in FMF patients were searched through binary logistic regression.Results580 FMF patients and 102 fibromyalgia subjects, 1012 Behçet’s disease patients and 497 Still’s disease patients were enrolled. The RR for the occurrence of malignant neoplasms was 0.26 (95% Confidence Interval [CI.] 0.10-0.73, p=0.006) in patients with FMF compared to fibromyalgia subjects; the RR for the occurrence of malignant cancer was 0.51 (95% CI. 0.23-1.16, p=0.10) in FMF compared to Still’s disease and 0.60 (95% CI. 0.29-1.28, p=0.18) in FMF compared to Behçet’s disease. At logistic regression, the risk of occurrence of malignant neoplasms in FMF patients was associated with the age at disease onset (β1 = 0.039, 95% CI. 0.001-0.071, p=0.02), the age at the diagnosis (β1 = 0.048, 95% CI. 0.039-0.085, p=0.006), the age at the enrolment (β1 = 0.05, 95% CI. 0.007-0.068, p=0.01), the number of attacks per year (β1 = 0.011, 95% CI. 0.001- 0.019, p=0.008), the use of biotechnological agents (β1 = 1.77, 95% CI. 0.43-3.19, p=0.009), the use of anti-IL-1 agents (β1 = 2.089, 95% CI. 0.7-3.5, p=0.002).ConclusionsThe risk for cancer is reduced in Caucasic FMF patients; however, when malignant neoplasms occur, this is more frequent in FMF cases suffering from a severe disease phenotype and presenting a colchicine-resistant disease.

Summary:. The traumatic pathology of the lower limb represents a very complex branch of medicine, which, despite the wide presence of guidelines, aimed at regulating the various therapeutic procedures, and is still greatly influenced by random variables and by the multiple responses to treatments. In this report, we present our experience with a borderline case, where the timing of the trauma and the patient’s characteristics made it difficult to use the most recommended procedures in trauma management.

Aging represents a decline in function over time. Polyphenols are dietary antioxidants that could exert beneficial effects on aging. This study investigated the effects of dietary supplementation with two extracts from Thymbra spicata L. aerial parts on the lifespan, body-weight control, and antioxidant responses of Drosophila melanogaster cohorts distinguished for age and sex. The aqueous extract extended the lifespan of young female flies, and this pro-longevity potential was associated with a reduction in the body-weight gain. Furthermore, the aqueous extract promoted the antioxidant defense when young females were exposed to Paraquat by reducing oxidative stress and mortality. This study provides the first insight into the beneficial effects of T. spicata supplementation in an animal model, suggesting that the healthy effect could mainly depend on strengthening the antioxidant defenses which reflect on the lifespan. Further investigations will better clarify the mechanisms and potential of T. spicata as nutraceutics in anti-aging strategies.

Venous thromboembolism (VTE), clinically manifested as deep vein thrombosis (DVT) or acute pulmonary embolism (PE), is the third most common acute cardiovascular syndrome following myocardial infarction and stroke. The annual incidence of PE is between 39 and 115 per 100,000 inhabitants. The incidence of VTE is almost eight times higher in people aged 80 and older than in the fifth decade of life. We performed a retrospective study of 226 COVID-19 patients and selected group of patients who experienced a pulmonary thrombotic event. The incidence of PE in hospitalized COVID-19 patients was approximately 1.9-8.9%. The retrospective nature of the analyzed cohorts and relatively short observation periods could have led to underestimation of the actual incidence of PE. This study underlines the role of novel inflammatory biomarkers such as neutrophil to lymphocyte ratio and platelet to lymphocyte ratio in patients with a pulmonary thrombotic event in COVID-19. We suggest that these biomarkers may have high assessment value and complement routinely used biomarkers.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a common condition with heterogeneous outcomes difficult to predict at the individual level. Feared complications of advanced MASLD are linked to clinically significant portal hypertension and are initiated by functional and mechanical changes in the unique sinusoidal capillary network of the liver. Early sinusoidal vasoregulatory changes in MASLD lead to increased intrahepatic vascular resistance and represent the beginning of portal hypertension. In addition, the composition and function of gut microbiota in MASLD are distinctly different from the healthy state, and multiple lines of evidence demonstrate the association of dysbiosis with these vasoregulatory changes. The gut microbiota is involved in the biotransformation of nutrients, production of de novo metabolites, release of microbial structural components, and impairment of the intestinal barrier with impact on innate immune responses, metabolism, inflammation, fibrosis, and vasoregulation in the liver and beyond. The gut–liver axis is a conceptual framework in which portal circulation is the primary connection between gut microbiota and the liver. Accordingly, biochemical and hemodynamic attributes of portal circulation may hold the key to better understanding and predicting disease progression in MASLD. However, many specific details remain hidden due to limited access to the portal circulation, indicating a major unmet need for the development of innovative diagnostic tools to analyze portal metabolites and explore their effect on health and disease. We also need to safely and reliably monitor portal hemodynamics with the goal of providing preventive and curative interventions in all stages of MASLD. Here, we review recent advances that link portal metabolomics to altered sinusoidal vasoregulation and may allow for new insights into the development of portal hypertension in MASLD.

IntroductionThe effectiveness of canakinumab may change according to the different times it is used after Still’s disease onset. This study aimed to investigate whether canakinumab (CAN) shows differences in short- and long-term therapeutic outcomes, according to its use as different lines of biologic treatment.MethodsPatients included in this study were retrospectively enrolled from the AutoInflammatory Disease Alliance (AIDA) International Registry dedicated to Still’s disease. Seventy-seven (51 females and 26 males) patients with Still’s disease were included in the present study. In total, 39 (50.6%) patients underwent CAN as a first-line biologic agent, and the remaining 38 (49.4%) patients were treated with CAN as a second-line biologic agent or subsequent biologic agent.ResultsNo statistically significant differences were found between patients treated with CAN as a first-line biologic agent and those previously treated with other biologic agents in terms of the frequency of complete response (p =0.62), partial response (p =0.61), treatment failure (p >0.99), and frequency of patients discontinuing CAN due to lack or loss of efficacy (p =0.2). Of all the patients, 18 (23.4%) patients experienced disease relapse during canakinumab treatment, 9 patients were treated with canakinumab as a first-line biologic agent, and nine patients were treated with a second-line or subsequent biologic agent. No differences were found in the frequency of glucocorticoid use (p =0.34), daily glucocorticoid dosage (p =0.47), or concomitant methotrexate dosage (p =0.43) at the last assessment during CAN treatment.ConclusionCanakinumab has proved to be effective in patients with Still’s disease, regardless of its line of biologic treatment.

The serum creatinine/cystatin C ratio (CCR) and the sarcopenia index (SI) are novel indicators for sarcopenia, but their accuracy may depend on various confounders. To assess CCR and SI diagnostic accuracy, we studied the clinical and biophysical parameters associated with sarcopenia or sarcopenic obesity. A total of 79 elderly patients (65–99 yrs, 33 females) underwent clinical, anthropometric, body composition, geriatric performance, and blood chemistry evaluation. The CCR and SI accuracy were assessed to identify sarcopenia. Sarcopenia was confirmed in 40.5%, and sarcopenic obesity in 8.9% of the subjects. Sarcopenic patients showed an increased Charlson comorbidity index, cardiovascular disease (CVD) rates and frailty, and decreased physical performance than non-sarcopenic subjects. Patients with sarcopenic obesity had increased body fat and inflammatory markers compared to obese subjects without sarcopenia. Sarcopenia was associated with a decreased CCR and SI. However, when the logistic regression models were adjusted for possible confounders (i.e., age, gender, Charlson comorbidity index, presence of CVD, and frailty score), a significant OR was confirmed for the CCR (OR 0.021, 95% CI 0.00055–0.83) but not for the SI. The AUC for the CCR for sarcopenia discrimination was 0.72. A higher performance was observed in patients without chronic kidney diseases (CKD, AUC 0.83). CCR, more than the SI, is a useful, non-invasive, and cost-effective tool to predict sarcopenia, irrespective of the potential confounders, particularly in subjects without CKD.

Spitzoid melanoma is very rare tumour in the pediatric population, with clinical and non-uniform behaviour, different from adult melanoma [1]. It can be difficult to differentiate an atypical Spitz nevus from a Spitzoid melanoma, resulting in diagnostic problems. In addition, in our clinical case, the COVID-19pandemiccaused significant delays both in the diagnosis and in the surgical treatment of our patient.We present the clinical case of a 4-year-old child suffering from a localized polypoid cutaneous neoformation on the dorsum of the left hand, which started immediately before the lockdown and steadily increased during the COVID-19 pandemic. After a general clinical framing, the child underwent an excisional biopsy at our Department of Plastic and Reconstructive Surgery, at the Policlinico of Foggia. Subsequently, two independent anatomic pathology groups examined the specimen. Definitive diagnosis was made only after careful genetic analysis in combination with supporting histological and immunohistochemical examinations.This clinical case shows how during the pandemic we have been facing advanced forms of tumours, compared to the previous period and highlight show an interdisciplinary and multicenter collaboration allowed a quick diagnosis of certainty, demonstrating the utility of molecular pathology as a fundamental aid in clinical/surgical practice.

Patients with irritable bowel syndrome (IBS) often associate their symptoms to certain foods. In congenital sucrase-isomaltase deficiency (CSID), recessive mutations in the SI gene (coding for the disaccharidase digesting sucrose and 60% of dietary starch)1 cause clinical features of IBS through colonic accumulation of undigested carbohydrates, triggering bowel symptoms.2 Hence, in a previous study,3 we hypothesized that CSID variants reducing SI enzymatic activity may contribute to development of IBS symptoms. We detected association with increased risk of IBS for 4 rare loss-of-function variants typically found in (homozygous) CSID patients, because carriers (heterozygous) of these rare variants were more common in patients than in controls.1,4 Through a 2-step computational and experimental strategy, the present study aimed to determine whether other (dys-)functional SI variants are associated with risk of IBS in addition to known CSID mutations. We first aimed to identify all SI rare pathogenic variants (SI-RPVs) on the basis of integrated Mendelian Clinically Applicable Pathogenicity (M-CAP) and Combined Annotation Dependent Depletion (CADD) predictive (clinically relevant) scores; next, we inspected genotype data currently available for 2207 IBS patients from a large ongoing project to compare SI-RPV case frequencies with ethnically matched population frequencies from the Exome Aggregation Consortium (ExAC).

Background & aimsGenetic factors are believed to affect risk for irritable bowel syndrome (IBS), but there have been no sufficiently powered and adequately sized studies. To identify DNA variants associated with IBS risk, we performed a genome-wide association study (GWAS) of the large UK Biobank population-based cohort, which includes genotype and health data from 500,000 participants.MethodsWe studied 7,287,191 high-quality single nucleotide polymorphisms in individuals who self-reported a doctor's diagnosis of IBS (cases; n = 9576) compared to the remainder of the cohort (controls; n = 336,499) (mean age of study subjects, 40-69 years). Genome-wide significant findings were further investigated in 2045 patients with IBS from tertiary centers and 7955 population controls from Europe and the United States, and a small general population sample from Sweden (n = 249). Functional annotation of GWAS results was carried out by integrating data from multiple biorepositories to obtain biological insights from the observed associations.ResultsWe identified a genome-wide significant association on chromosome 9q31.2 (single nucleotide polymorphism rs10512344; P = 3.57 × 10-8) in a region previously linked to age at menarche, and 13 additional loci of suggestive significance (P < 5.0×10-6). Sex-stratified analyses revealed that the variants at 9q31.2 affect risk of IBS in women only (P = 4.29 × 10-10 in UK Biobank) and also associate with constipation-predominant IBS in women (P = .015 in the tertiary cohort) and harder stools in women (P = .0012 in the population-based sample). Functional annotation of the 9q31.2 locus identified 8 candidate genes, including the elongator complex protein 1 gene (ELP1 or IKBKAP), which is mutated in patients with familial dysautonomia.ConclusionsIn a sufficiently powered GWAS of IBS, we associated variants at the locus 9q31.2 with risk of IBS in women. This observation may provide additional rationale for investigating the role of sex hormones and autonomic dysfunction in IBS.

Background Keloids are pathological scars characterized by nodular fibrous tissue that extends beyond the border of initial damage. These lesions do not spontaneously regress and can cause cosmetic disfigurements and functional disabilities. IntraLesional Injection of Triamcinolone Acetonide (ILITA), alone or in combination with other therapy, is one of the first-line treatment modalities. In this study the authors evaluated the objective efficacy of ILITA treatment in keloids management using this new imaging system. Materials and Methods 37 patients with 45 keloid scars were treated with intralesional injection of triamcinolone acetonide (TAC) 20 mg/ml at an interval of three weeks. Antera3D® camera took the images and dates of the treated area in each patient, before the treatment (T0) and at three weeks after the last injection (T1). The system processed the levels of color, elevations, melanin and hemoglobin expression. All the scars were also evaluated, at the same times, by validated Vancouver Scar Scale (VSS). Comparison of the variables was performed using a Wilcoxon signed-rank test with a p

Management of patients is a great challenge for physicians; at the present, the therapeutic strategy aimed to treat the different symptoms, and no medical therapy is proven to modify the natural history of the disease. GELSECTAN® (xyloglucan, pea protein and tannins, xylo-oligosaccharides) is a medical device with both protective and prebiotic actions on the intestinal mucosa, able to restore intestinal permeability and to improve gastrointestinal symptoms, controlling diarrhoea, abdominal pain and bloating in adult patients with irritable bowel syndrome. We report and discuss four cases of different patients with irritable bowel syndrome successfully managed with Gelsectan in the real clinical practice. Literature data, as well as these case reports, show that this device is effective and safe in improving symptoms and bowel habits associated to irritable bowel syndrome; its efficacy and safety were confirmed for the long-term use too. Agents with film-forming protective properties, such as Gelsectan, represent a new alternative therapeutic option for the management of patients with irritable bowel syndrome.Keywords: irritable bowel syndrome, GELSECTAN®, xyloglucan, tannins, xylo-oligosaccharides

Abstract Background Dermatofibrosarcoma protuberans (DFSP) is a rare skin fibroblastic tumor, with a high rate of recurrence. The treatment of DFSP is generally surgical, and wide local excision is the mainstay of surgical treatment. Therefore, complete assessment of all surgical margins is fundamental before definitive reconstruction. The reconstruction is a challenge for plastic surgeons, especially in particular anatomical areas (for aesthetic or functional problems) or in patients who are not candidates for more complex surgical treatments. We describe an alternative approach for reconstructive treatment of the lumbar area after wide excision of DFSP (without fresh-frozen sections) in a young obese woman with a history of smoking, using a new type of acellular dermal matrix (ADM) in a combined management protocol. The benefits of ADM are numerous: immediate wound closure and prevention of infections and excessive drying; minimal donor site morbidity; and good functional and aesthetic outcomes. Moreover, it is a temporary cover while the anatomical specimen is histologically analyzed, without donor site morbidity or prevention of any future surgery (if the margins are not tumor-free) or radiotherapy. Case presentation In October 2019, a 34-year old obese Caucasian Woman with a history of smoking came to our institute for a multinodular growing polypoid mass in her lumbar region. An incisional biopsy diagnosed DFSP. The patient underwent proper staging. A wide local excision with 3 cm clinically healthy tissue margins down to the muscle fascia was performed and the defect was repaired using a combined approach with a new artificial bilaminar dermal template (Pelnac®, Gunze Ltd., Osaka, Japan) and a negative-pressure wound therapy system (V.A.C.®, KCI, San Antonio, USA). After the final histological examination revealed tumor-free margins, a split-thickness graft was harvested from the right gluteus and fixed to the new derma with negative-pressure wound therapy. Postoperative radiotherapy was not necessary. After 15 days, the wound had healed without complications, with satisfactory aesthetic outcome and with no limitation of back motion or pain. After 6 months of follow-up, the patient was free from disease. Conclusions This is the first reported case of Pelnac® use in DFSP reconstruction of the lumbar region. We believe that the multistep approach described herein may be a good alternative approach in selected patients with wide resections in particular anatomical areas, especially when frozen sections (with Mohs micrographic surgery) are not available.

Abstract Background Epidermolysis bullosa (EB) comprises a heterogeneous group of rare genetic diseases associated with skin blistering caused by minimal trauma. A major and common EB subtype, recessive dystrophic EB (RDEB), is characterized by altered wound healing, inflammatory dysbalance and fibrotic changes associated with reduced to absent collagen VII. Because of its exposed position and its continued use in daily activities, the hand is constantly at risk of microtrauma and is therefore one of the organs most affected by the disease with highly disabling deformities that represent a challenging field in hand surgery practice. Methods The authors present their experience in the microsurgical treatment of pseudosyndactylies comparing the classic dressing with vaseline gauze with an innovative “glove protocol” using Integra® dermal regeneration template. The endpoints analyzed were: healing times, hospital stay time, discomfort for the patient, free-recurrence interval, follow-up range and major complications. Results A total of 34 procedures were performed on 24 RDEB patients with hand deformities. Compared with the dressing with vaseline gauze, microsurgery followed by application of dermal regeneration template gloves allowed a significant reduction of hospital stay, healing time, and dressing pain as well as an increased recurrence-free interval. Conclusions The microsurgical approach followed by our new protocol described in the study has been beneficial in providing consistent and successful long-term results for these patients.

Interest in plant-based food has grown in recent years due to their primary prevention potential. Za’atar, an ancient and popular Lebanese herbal mixture, might disclose relevant clinical interest, due to the well-known intrinsic properties of its individual components. Za’atar mixture contain Origanum syriacum (Lebanese thyme), Thymbra spicata (Wild thyme), Rhus coriaria (Sumac), and Sesamum indicum (Sesame). Here we explored the history, composition, general employment, and bio-active aspects of Za’atar through available in vitro, animal, and clinical trials evidence to depict its possible role as an innovative nutraceutical tool. The combined action of Za’atar constituents is able to generate comprehensive beneficial effects on several common pathogenic pathways underlying chronic cardio-metabolic diseases and cancer. However, main available evidence derives from animal and in vitro studies. Thus, further human studies are needed to fully characterize Za’atar as a preventive and curative tool.

Sufficient caloric intake is important to maintain the balanced health status, especially during the period of aging, as aging and sickness share paths. Maintaining adequate nutritional balance is the best preventive measure to counteract the risk of malnutrition. There are several causes for malnutrition in elderly people, and some techniques such as anthropometric measurements, laboratory and clinical parameters could help to diagnose malnutrition in these patients. The use of a simple validated questionnaire called the ‘Mini Nutritional Assessment’ measures the nutritional status of elderly patients. In this review, we discuss about the malnutrition in elderly people with and without a known cause and we present some of nutritional intervention. There are promising strategies that help overcoming malnutrition.

Background: There are no evidence-based recommendations for performing upper gastrointestinal endoscopy (UGIE) in patients with extra-oesophageal symptoms of gastro-oesophageal reflux disease (GORD). However, UGIEs are often performed in clinical practice in these patients. We aimed to assess the prevalence of gastro-oesophageal lesions in patients with atypical GORD symptoms. Methods: Patients complaining of at least one extra-oesophageal GORD symptom and undergoing UGIE in seven centres were prospectively enrolled. Clinically relevant lesions (Barrett’s oesophagus, erosive oesophagitis, gastric precancerous conditions, peptic ulcer, cancer, and H. pylori infection) were statistically compared between groups regarding GORD symptoms (atypical vs. both typical and atypical), type of atypical symptoms, age, and presence of hiatal hernia. Results: Two hundred eleven patients were enrolled (male/female: 74/137; mean age: 55.5 ± 14.7 years). Barrett’s oesophagus was detected in 4 (1.9%), erosive oesophagitis in 12 (5.7%), gastric precancerous conditions in 22 (10.4%), and H. pylori infection in 38 (18%) patients. Prevalence of clinically relevant lesions was lower in patients with only atypical GORD symptoms (28.6 vs. 42.5%; p = 0.046; χ2 test), in patients ≤50 years (20 vs. 44.8%; p = 0.004; χ2 test), and in those in ongoing proton pump inhibitor (PPI) therapy (21.1 vs. 40.2%; p = 0.01; χ2 test). No clinically relevant lesions were detected in patients ≤50 years, without alarm symptoms, and receiving PPI therapy. Hiatal hernia was diagnosed in only 6 patients with cardiologic and in 41 patients with ear-nose-throat symptoms (11.3 vs. 35.1%; p = 0.03; χ2 test). Conclusions: Clinically relevant lesions are uncommon among young (≤50 years) patients with extra-oesophageal GORD symptoms. Hiatal hernia is not more prevalent in patients with cardiologic symptoms and suspicion of GORD. The usefulness of UGIE in these patients is questionable.

Since the gut microbiota plays a pivotal role in host homeostasis and energy balance, changes in its composition can be associated with disease states through the promotion of immune-mediated inflammatory disorders and increasing intestinal permeability, ultimately leading to the impairment of intestinal barrier function. Za’atar is one of the most popular plant-based foods in the Eastern Mediterranean region. Za’atar is a mixture of different plant leaves, fruits, and seeds and contains hundreds of antioxidant compounds, especially polyphenols, and fiber, with pre-clinical and clinical evidence suggesting health-promoting effects in cardiovascular and metabolic disease. Za’atar compounds have also been studied from a gastrointestinal perspective, concerning both gut microbiota and gastrointestinal diseases. Antioxidants such as Za’atar polyphenols may provide beneficial effects in the complex interplay between the diet, gut microbiota, and intestinal permeability. To our knowledge, no studies have reported the effects of the whole Za’atar mixture, however, based on the pre-clinical studies published on components and single compounds found in Za’atar, we provide a clinical overview of the possible effects on the gastrointestinal tract, focusing mainly on carvacrol, rosmarinic acid, gallic acid, and other polyphenols. We also cover the potential clinical applications of Za’atar mixture as a possible nutraceutical in disorders involving the gastrointestinal tract.

Sumac (Rhus coriaria L.) is a commonly used spice in the Mediterranean region and considered as healthy food ingredients. The beneficial value of sumac is well documented in folk medicine. Accumulating data explored the phytochemical, nutritional and therapeutic proprieties suggesting sumac as a potential functional food. Here, we discuss the general and scientific aspects of sumac. Sumac is rich in different polyphenolic compounds such as flavonoids, tannins, and phenolic acids. The potential therapeutic effects of sumac have been studied in various cellular and animal models, as well as in human. These reports suggest that Sumac has potential effect against oxidative stress, inflammation, obesity, hyperglycemia, hypercholesterolemia, and hyperlipidemia, which represent key pathogenic mechanisms contributing to cardio-metabolic, liver, and cancer diseases. Clinical studies using sumac or its major compounds, suggest that this herbal product may represent a useful therapeutic tool in the management of metabolic-related conditions such as liver-atherosclerosis complications.
