Cultivation of Protozoa Parasites In Vitro: Growth Potential in Conventional Culture Media versus RPMI-PY Medium.

The in vitro cultivation of Leishmania and Trypanosoma parasites plays an important role in the diagnosis and treatment of parasitic diseases. Although Evans's modified Tobie and Novy-MacNeal-Nicolle media, for and , respectively, are the two commonly used media for both isolation and maintenance of strains in vitro, their preparation is expensive and laborious and requires fresh rabbit blood from housed animals. The purpose of this study was to evaluate the in vitro growth of both parasites with an alternative monophasic, blood-free, easy, and affordable medium called RPMI-PY, which was previously demonstrated suitable for the in vitro growth of .

Leishmaniasis is an important vector-borne disease that represents a serious public health problem, including in Sicily (Italy), which is considered an endemic area. We collected canine, feline and human data from 2013 to 2021 in Sicily, while entomological surveys were conducted only in 2013 and 2021. Overall, 23,794/74,349 (34.

Does Heparin Affect Tc-MAA In Vitro Stability?

Introduction: Pulmonary embolism (PE) can be diagnosed by perfusion lung scintigraphy using human albumin macroaggregates labelled Tc (Tc-MAA). When PE is suspected, subcutaneous Low Molecular Weight Heparin (LMWH) should be administered even before the results of the PE diagnostic flowchart. In our study, we aimed to evaluate a possible interaction (in vitro interference) between Tc-MAA and LMWH.

Oropharyngoesophageal Scintigraphy in a Case of Complex Swallowing Disorders After a Major Oral Surgery.

A 75-year-old woman had an occasional finding of a left tonsil mass for dysphagia, which resulted a high-grade squamous carcinoma. Therefore, the patient was sent to have a left pharyngectomy. After the pharyngectomy, the patient reported persistent swallowing disorders and nasal reflux.

Molecular Diagnosis of Leishmaniasis: Quantification of Parasite Load by a Real-Time PCR Assay with High Sensitivity.

Real-time PCR was developed to quantify kinetoplast DNA and optimized to achieve a sensitivity of 1 parasite/mL. For this purpose, we cloned the conserved kDNA fragment of 120 bp into competent cells and correlated them with serial dilutions of DNA extracted from reference parasite cultures calculating that a parasite cell contains approximately 36 molecules of kDNA. This assay was applied to estimate parasite load in clinical samples from visceral, cutaneous leishmaniasis patients and infected dogs and cats comparing with conventional diagnosis.

Clinical characteristics of metabolic associated fatty liver disease (MAFLD) in subjects with myotonic dystrophy type 1 (DM1).

Background: Myotonic dystrophy type 1 (DM1) is a rare inherited neuromuscular disease associated with insulin resistance, and its association with metabolically associated fatty liver disease (MAFLD) has never been explored in prospective studies. The aim of this study was to assess the clinical features of MAFLD in DM1 patients.

Methods: We investigated the prevalence and the diagnostic features of MAFLD in a cohort of 29 outpatient fully characterized DM1 patients; afterward, we compared the selected cohort of DM1-MAFLD individuals with a propensity-matched cohort of non-DM1-MAFLD RESULTS: 13/29 (44.

Impact of Tracheal Tube on Swallowing in Post-Operative Head and Neck Cancer Patients: Scintigraphic Analysis.

Dysphagia is common in tracheostomized patients who underwent head and neck surgery for cancer treatment. The objective of this study was to evaluate, by means of oropharyngoesophageal scintigraphy (OPES), the impact of an occluded tracheal tube (TT) on swallowing in patients treated for head and neck cancer before hospital discharge, to provide further information to the benefit of out-patient care management. From October 2018 to November 2019, we enrolled 19 tracheostomized patients (6 females and 13 males; mean age 61 years) who underwent primary surgical resection of head and neck tumor and swallowing rehabilitation during hospitalization.

High Prevalence and Gender-Related Differences of Gastrointestinal Manifestations in a Cohort of DM1 Patients: A Perspective, Cross-Sectional Study.

Myotonic dystrophy type 1 (DM1, MIM #160900), the most common muscular dystrophy among adults, is a multisystem disorder, which affects, besides the skeletal muscle, several other tissues and/or organs, including the gastrointestinal apparatus, with manifestations that frequently affect the quality of life of DM1 patients. So far, only few, mainly retrospective studies evaluated this specific topic in DM1, so we performed a perspective study, enrolling 61 DM1 patients who underwent an extensive diagnostic protocol, including administration of the Gastrointestinal Symptom Rating Scale (GSRS), a validated patient-reported questionnaire about GI symptoms, laboratory tests, liver US scan, and an intestinal permeability assay, in order to characterize frequency and assess correlations regarding specific gastrointestinal manifestations with demographic or other DM1-related features. Our results in our DM1 cohort confirm the high frequency of various gastrointestinal manifestations, with the most frequent being constipation (45.

Effect of liver transplantation on intestinal permeability and correlation with infection episodes.

Background: Liver cirrhosis has been known to be associated with increased intestinal permeability (IP); however, little is known about the modification of IP after liver transplantation (LT). The present study was aimed to assess IP after LT and evaluated its association with laboratory tests and clinical parameters, as well as with the development of infections.

Methods: LT recipients were consecutively enrolled and compared with an equal number of patients with liver cirrhosis and healthy subjects.

Intestinal permeability in the pathogenesis of liver damage: From non-alcoholic fatty liver disease to liver transplantation.

The intimate connection and the strict mutual cooperation between the gut and the liver realizes a functional entity called gut-liver axis. The integrity of intestinal barrier is crucial for the maintenance of liver homeostasis. In this mutual relationship, the liver acts as a second firewall towards potentially harmful substances translocated from the gut, and is, in turn, is implicated in the regulation of the barrier.

Intestinal permeability after Mediterranean diet and low-fat diet in non-alcoholic fatty liver disease.

Background: In non-alcoholic fatty liver disease (NAFLD), a high-fat or high-fructose diet increases intestinal permeability and promotes derangement of the gut-liver axis. We hypothesize that, diet could be able to modulate intestinal permeability in patients with NAFLD.

Aim: To detect diet-induced modification of intestinal permeability in patients with NAFLD undergoing a Mediterranean diet or a low-fat diet.

Bile Collection Detected With BrIDA Scintigraphy in a Patient With Hepatocellular Carcinoma.

A 47-year-old man, with a history of anabolic steroid abuse, developed hepatic adenomatosis and multifocal hepatocellular carcinoma. He underwent ultrasound and CT follow-up, showing multiple solid and fluid hepatic lesions. Consequently, hospitalization was required because of high fever (up to 39°C), weakness, and anorexia.

Recurrent pregnancy loss is associated to leaky gut: a novel pathogenic model of endometrium inflammation?

Background: Recurrent pregnancy loss (RPL) occurs in 3-5% in about 30% of cases no cause can be found. Women with RPL show higher prevalence of undiagnosed gut disorders. Furthermore, in endometrial tissues of RPL women, higher expression of pro-inflammatory cytokines and Nalp-3 inflammasome has been observed.

Irritable Bowel Syndrome and Nickel Allergy: What Is the Role of the Low Nickel Diet?

Background/aims: Irritable bowel syndrome (IBS) is characterized by chronic abdominal pain or discomfort accompanied by abnormal bowel movements. In sensitized subjects, ingested nickel (Ni) may induce gastrointestinal symptoms similar to IBS, in addition to typical systemic cutaneous lesions (systemic nickel allergy syndrome [SNAS]). A low nickel diet could improve the systemic manifestations.

Evaluation of swallowing function after supracricoid laryngectomy as a primary or salvage procedure.

The primary functional issues following conservative therapy for advanced laryngeal cancer concern swallowing. Here, we evaluated the recovery of swallowing after supracricoid partial laryngectomy (SCL) in patients with primary or recurrent laryngeal cancer. We evaluated the swallowing recovery in 27 SCL patients through oropharyngoesophageal scintigraphy, and we evaluated their quality of life using EORTC questionnaires.

Prevalence and clinical correlates of sleep disordered breathing in myotonic dystrophy types 1 and 2.

Purpose: Myotonic dystrophy types 1 (DM1) and 2 (DM2) are the most common muscular dystrophies in adulthood. A high prevalence of excessive daytime sleepiness (EDS) and sleep disordered breathing was documented in DM1; however, there are limited data available regarding DM2. Goals of the study were: (1) to evaluate the prevalence of sleep apnea in a large cohort of patients (71 DM1 and 14 DM2) and (2) to analyze correlations among such disorders and clinical features of myotonic dystrophies.

Long-term treatment of severe SAPHO syndrome with adalimumab: case report and a review of the literature.

SAPHO (synovitis, acne, pustulosis, hyperostosis, and osteitis) syndrome defines an association of inflammatory cutaneous disorders with osteoarticular manifestations and represents a clinical and therapeutic challenge. We report a case of severe SAPHO syndrome with acne conglobata and a diffuse involvement of the anterior chest wall and sacroiliac joints that required treatment with isotretinoin and adalimumab, a new fully human anti-tumor necrosis factor (TNF)-α monoclonal antibody. Combination treatment determined a complete clinical remission of cutaneous and osteoarticular manifestations after 48 weeks.

Surgical prophylaxis of pouchitis in ulcerative colitis.

Ileal pouch-anal anastomosis (IPAA) is now the procedure of choice for most patients requiring proctocolectomy for ulcerative colitis. The J-shaped pouch, usually 15-20 cm in length, is easiest to construct and has functional outcomes identical to those of the more complex designs. IPAA is a complex procedure, and complications occur frequently.

Pharyngocutaneous fistula onset after total laryngectomy: scintigraphic analysis.

Pharyngocutaneous fistula is the most common non-fatal complication following total laryngectomy. To start oral feeding and exclude the presence of a pharyngocutaneous fistula, a subjective test and instrumental assessments using videofluoroscopy, have been described. The aim of this study was to evaluate the effectiveness of oral-pharyngo-oesophageal scintigraphy as an objective and non-invasive tool to establish presence, site and dimensions of the fistula.

Intestinal permeability in cirrhotic patients with and without spontaneous bacterial peritonitis: is the ring closed?

Objectives: Impaired intestinal permeability (IP) may have a role in the pathogenesis of ascites and in spontaneous bacterial peritonitis (SBP) in patients with liver cirrhosis (LC). The aim of this study was to assess IP in LC patients with respect to healthy controls.

Methods: IP was evaluated by the (51)Cr-ethylenediaminetetraacetic acid ((51)Cr-EDTA) permeability test in 52 LC patients and in 48 sex- and age-matched controls.

Increased intestinal permeability and tight junction alterations in nonalcoholic fatty liver disease.

Unlabelled: The role played by the gut in nonalcoholic fatty liver disease (NAFLD) is still a matter of debate, although animal and human studies suggest that gut-derived endotoxin may be important. We investigated intestinal permeability in patients with NAFLD and evaluated the correlations between this phenomenon and the stage of the disease, the integrity of tight junctions within the small intestine, and prevalence of small intestinal bacterial overgrowth (SIBO). We examined 35 consecutive patients with biopsy-proven NAFLD, 27 with untreated celiac disease (as a model of intestinal hyperpermeability) and 24 healthy volunteers.
