RESUMO
NTRODUCTION: Distal pancreatectomy is a standard surgical procedure for selected benign, premalignant, and malignant lesions localized in the pancreatic body or tail. Surgical resection remains the only curative option for patients diagnosed with adenocarcinoma of the pancreas. PATIENTS AND METHODS: Perioperative and postoperative clinical courses were retrospectively assessed in patients, who underwent distal pancreatectomy during the 2011â2021 period. RESULTS: During the 2011â2021 period, a total of 112 distal pancreatectomies were performed. 67 patients (59.8%) underwent laparoscopic distal pancreatectomy, and 45 patients (40.2%) open laparotomy. The conversion was necessary for 13 patients (11.6%). Distal pancreatectomies performed laparoscopically were associated more often with biochemical leak and the development of grade B fistula, on the other hand grade C fistula developed only in patients operated by open laparotomy (LPT). The mean operating time was slightly longer in the laparoscopic group (227.1 min vs 214.6 min). The mean estimated blood loss was significantly higher in the LPT group (540.4 ml vs 191.9 ml). The mean hospitalization time was slightly longer in the LPT group (11.8 days vs 9.3 days). The rates of early reoperations were comparable between both groups (6 vs 5). CONCLUSION: Laparoscopic techniques are preferred in centers around the world to bring patients benefits by using a minimally invasive approach. These techniques are also preferred in our center, in nearly 60% of all distal pancreatectomies performed during 10 years, but on the other hand, there is a much more careful approach chosen in cases of malignant disease to achieve adequate radicality (Tab.4, Ref. 20).

PURPOSE: The aim of this study was to define the values of percutaneous ultrasound shear-wave and strain elastography of the pancreas in healthy volunteers. METHODS: This is a single-center prospective study conducted on volunteers who underwent examination of percutaneous point shearwave elastography and strain elastography. Both the shear-wave speed (Vs) and strain histogram were measured 3 times and median values were evaluated. Relevant recorded clinical data were age, sex, and height. RESULTS: From May 2020 to October 2021 a total of 90 patients (21 male, 69 female) were included in the study. Their average age was 26 years (from 22 to 65). The average SWM in kPa was 6.07 (2.58-17.29). The average value of SE was 134.44 (78.51-184.35). Most of the patients had BMI in the range of normal weight with an average value of 22.75 (17.5-28). The average depth of the localization of the pancreas was 4.5 cm. The effect of BMI on the strain histogram was significant (p < 0.05). We found a significant relationship between the strain histogram and the depth of localization of the pancreas (p < 0.01). CONCLUSION: We described normal values for pancreatic stiffness using ultrasound elastography by 2D-SWE and strain elastography. Our results indicate changes in values depending on BMI and depth of the pancreas. (Tab. 1, Fig. 5, Ref. 19).

Menthol is thought to trigger gastroesophageal reflux disease (GERD) symptoms by influencing esophageal peristalsis and lower esophageal sphincter (LES) function. We evaluated the effect of esophageal menthol infusion on esophageal motility and the LES in healthy volunteers and in patients with GERD. High resolution manometry (HRM) catheter with attached thin tube for menthol infusion was placed transnasally. Protocol which included baseline recording, 16 water swallows (5 ml, 10 ml, and 15 ml) and the multiple rapid swallows was performed before and after esophageal infusion of menthol (3 mM, 20 min, 8 ml/min). We evaluated the effect of this infusion on the HRM parameters of esophageal peristalsis (distal contractile integral, distal latency, contractile front velocity) and the lower esophageal sphincter (LES) barrier function (integrated relaxation pressure and the inspiratory augmentation of the LES). Simultaneously we evaluated the quality and intensity of the symptoms during the menthol infusion. Esophageal infusion of menthol did not appreciably affect HRM measurements characterizing esophageal peristalsis and LES pressure in healthy subjects (N = 13) or GERD patients (N = 11). The magnitude of the distal contractile integral (5 ml) was changed neither in the healthy volunteers' group, (735 ± 127 vs. 814 ± 117 mmHg, p = 0.5), nor in the GERD patients (295 ± 78 vs. 338 ± 96 mmHg, p = 0.99). In healthy volunteers menthol did not change the inspiratory augmentation of the LES (8.67 ± 1.09 vs. 7.69 ± 0.96 mmHg, p = 0.15) and neither did for GERD patients (8.8 ± 1.18 vs. 8.22 ± 0.91 mmHg, p = 0.43). We observed no significant difference in any HRM parameter following menthol infusion, except for distal latency in 10 ml swallows. By contrast, menthol infusion induced significantly more intense discomfort in GERD patient than in healthy volunteers. Our results suggest no significant temporal effect of menthol on the esophageal motility or LES function, neither in healthy volunteers, nor in GERD. Arguably, other mechanisms are responsible for menthol-related heartburn.
RESUMO
Background and Objectives: COVID-19 infection may influence many physiological processes, including glucose metabolism. Acute hyperglycaemia has been related to a worse prognosis in patients with severe COVID-19 infection. The aim of our study was to find out if moderate COVID-19 infection is associated with hyperglycaemia. Materials and Methods: A total of 235 children were enrolled in the study between October 2021 and October 2022, 112 with confirmed COVID-19 infection and 123 with other RNA viral infection. In all patients, types of symptoms, glycaemia at the time of admission, and basic anthropometric and biochemical parameters were recorded. Results: Average glycaemia was significantly higher in COVID-19 patients compared to other viral infections (5.7 ± 1.12 vs. 5.31 ± 1.4 mmol/L, p = 0.011). This difference was more obvious in subgroups with gastrointestinal manifestations (5.6 ± 1.11 vs. 4.81 ± 1.38 mmol/L, p = 0.0006) and with fever (5.76±1.22 vs. 5.11±1.37 mmol/L, p = 0.002), while no significant difference was found in subgroups with mainly respiratory symptoms. The risk of hyperglycaemia (>5.6 mmol/L) was higher in COVID-19 patients compared to other viral infections (OR = 1.86, 95%CI = 1.10-3.14, p = 0.02). The risk of hyperglycaemia was significantly higher in COVID-19 compared to other viral infections in the subgroups of patients with fever (OR = 3.59, 95% CI 1.755-7.345, p = 0.0005) and with gastrointestinal manifestations (OR = 2.48, 95% CI 1.058-5.791, p = 0.036). Conclusion: According to our results, mild hyperglycaemia was significantly more common in children with moderate COVID-19 infection compared to other RNA virus respiratory and gastrointestinal infections, especially when accompanied by fever or gastrointestinal symptoms.

Background and Objectives: Severe non-variceal gastrointestinal bleeding is a life-threatening condition with complicated treatment if endoscopic therapy fails. In such cases, transcatheter arterial embolization is recommended. The technical and clinical effects of this technique were analyzed in this group of patients, as well as its complication rate and 30-day mortality. Materials and Methods: Patient data over a one-decade period (from 2010 to 2019) were analyzed retrospectively; 27 patients (18 men and 9 women; median age 61 years) treated by endovascular embolization in our institution, with clinically significant gastrointestinal hemorrhage after unsuccessful or impossible endoscopic treatment, were identified, and their data were collected. Results: The source of bleeding was found in 88% of patients, but embolization was performed in 96% of them. The overall technical success rate was 96.8%, and the clinical success was 88.5%. Re-bleeding occurred in eight cases, five of whom had re-embolization that was technically successful in four cases. The incidence of re-bleeding was significantly higher in patients with two or more comorbidities (p = 0.043). There was one serious complication (4%) in the group, and minor difficulties occurred in 18% of patients; 30-day mortality reached 22%. Mortality was significantly higher in the group of patients with re-bleeding (p = 0.044). Conclusions: Transcatheter arterial embolization is a mini-invasive method with high technical success in patients with endoscopically untreatable gastrointestinal bleeding; it is also suitable for high-risk cases. Mortality (to a significant extent) depends on the occurrence of re-bleeding and the patient's comorbidities.

Rupture of the spleen is a serious medical condition manifesting as a sudden abdominal event, potentially life-threatening. Spontaneous spleen rupture is a rare condition. Atraumatic rupture of the spleen is a very unlikely condition. Risk factors include splenomegaly, hemato-oncological diseases, and infections, such as malaria or infectious mononucleosis. Extremely rare is splenic rupture described in autoimmune disease or vasculitis. There has been no reported case of spontaneous splenic rupture as a first manifestation of Churg- Strauss syndrome so far.

In complex etiopathogenesis of diabetic peripheral neuropathy (DPN), hemostatic dysfunction and subclinical inflammation play a possible role. Fibrinogen is involved in both the hemostatic and inflammatory pathways, so we hypothesize that fibrinogen gene polymorphisms might be associated with DPN. A total of 127 young patients with type 1 diabetes (T1D) (average age, 18.5 ± 4.65 years; average diabetes duration, 14.5 ± 2.26 years) and 90 healthy controls were enrolled into the study. Basic biochemical and coagulation parameters were measured and gene polymorphisms of fibrinogen alpha (rs6050) and beta (rs1800790) were established. DPN was diagnosed in 38 diabetic patients by neurological examination. AA genotype and A allele of rs1800790 polymorphism of fibrinogen beta were associated with increased risk of DPN (odds ratio [OR] 4.537, 95% confidence interval [95CI] 1.14-19.94, p = 0.019 and OR 1.958, 95CI 1.038-3.675, p = 0.029, respectively). No association was found between DPN and rs6050 gene polymorphisms. Plasma fibrinogen concentration significantly correlated with HbA1c (Spearman's correlation coefficient [r] = 0.54) and HDL cholesterol (r = - 0.67). A allele and AA genotype of rs1800790 seem to be associated with DPN in young patients with T1D. Further studies are appropriate to elucidate the role of fibrinogen gene polymorphisms in the complex etiology of DPN.

BACKGROUND: Several studies demonstrated that proton pump inhibitors (PPIs) co-administrated with dabigatran in patients with atrial fibrillation (AF) decreased dabigatran trough and peak plasma levels. However, it is still unknown whether this interaction is reversible or not, and whether the withdrawal of PPI would lead to normalization of dabigatran plasma levels. AIM OF STUDY: The aim of this study was to determine the effect of PPI withdrawal on dabigatran plasma levels in patients with AF. METHODS: This pilot prospective study enrolled 23 AF patients on long-term dabigatran and PPI therapy (omeprazole 20 mg twice daily or pantoprazole 40 mg once daily). Dabigatran trough and peak levels (ng/mL) were tested on PPI and after a 2-week period of PPI withdrawal with Hemoclot Thrombin Inhibitor Assay. RESULTS: The analysis of dabigatran plasma levels demonstrated significant elevation in trough dabigatran levels after 2 weeks of PPI withdrawal (97.2 ± 79.7 vs. 163.8 ± 105.5 ng/mL; P < 0.05). Moreover, significantly higher peak dabigatran levels were observed after 2 weeks of PPI withdrawal (142.4 ± 102.8 vs. 255 ± 129.5 ng/mL; P ≤ 0.001). CONCLUSIONS: This study showed that a 2-week period of PPI withdrawal lead to a significant increase in dabigatran trough and peak plasma levels in patients with AF.

Background: Standard treatment for esophageal epiphrenic diverticula associated with achalasia includes surgical diverticulectomy, myotomy and anterior fundoplication. However, several case reports published recently suggest that endoscopic approach using per oral endoscopic myotomy is a safe and effective alternative.Methods: This is a retrospective review of a single center case series of patients with achalasia and epiphrenic diverticula. During the treatment, the POEM guided on the opposite site of the diverticular neck without diverticulotomy was performed. Symptomatic outcome was evaluated 3 months after procedure and afterwards with the median follow-up time of 24 months. High resolution manometry was performed 3 months after the procedure.Results: Seven patients with esophageal epiphrenic diverticula were included. POEM was successfully performed in all patients, with no complications in the periprocedural period. We observed a significant reduction of Eckardt score and the relaxation pressure of the lower esophageal sphincter (31.8 vs. 8.8 mmHg, p < .0001).Conclusions: POEM is a promising approach in the management of achalasia and esophageal epiphrenic diverticula. We demonstrated its safety, efficiency and ability to provide symptom reduction and decrease of the LES relaxation pressure even without diverticulotomy. Multicentric studies on larger cohorts of patients and with longer follow-up time are required to confirm these results.

There is no direct evidence for the exact cilia-inhibitory effects of opioids, which are generally used to achieve general anesthesia in combination with other anesthetic drugs. These are the reasons, why we analysed direct concentration-dependent or systemic effects of anesthetics (propofol, sufentanil, and midazolam) at a recommended doses administered individually or simultaneously on the tracheal ciliary beat frequency (CBF) in in vitro experimental conditions. Brush biopsy technique was used to remove the tracheal epithelia of guinea pigs for microscopy evaluation of ciliary beating monitored by high-speed video camera and analysed by Ciliary Analysis software. The tracheal CBF was significantly lower in the presence of sufentanil (10-8 mol/L) than in the control group; similarly for midazolam-sufentanil (10-8 - 10-5 mol/L), as well as for midazolam-propofol (10-5 and 10-3 mol/L) combinations. The fact that concurrent administration of benzodiazepine significantly increased the risk of sufentanil-induced cilia-inhibition was pharmacologically confirmed using GABAA receptor antagonist, bicuculline methiodide. The benefit of propofol on the potent cilia-inhibitory effect achieved by benzodiazepine-opioid combination was non-significant. We highlight the pharmacodynamics interaction between anesthetic drugs mediated via GABAA receptor with negative impact on the CBF in a respiratory epithelium under experimental condition rather than the effect of individual anesthetic.

We report a 2-year-old patient with Netherton syndrome presenting with generalized exfoliative erythroderma, ichthyosiform dermatitis, trichorrhexis invaginata, hypernatremic dehydration, failure to thrive, and recurrent respiratory infections. Molecular analysis of SPINK5 identified a novel mutation (c.1530CA). Our case report also verifies and supports the safety and efficacy of subcutaneous immunoglobulin substitution in chronic generalized skin disorders associated with primary immunodeficiencies such as Netherton syndrome.

Mixed connective tissue diseases (MCTD) is a very rare autoimmune disease connecting clinical signs of systemic lupus, systemic sclerosis, polymyositis and rheumatoid arthritis. Clinical manifestations are very diverse. In some patients, the digestive tract is affected in varying degrees. The esophagus is affected most often, and patients are complaining of dysphagia. Morphologically, this disorder is similar to the injure in systemic scleroderma. In this case, we describe a unique case of a severe damage of digestive tract manifested by esophageal motility disorders, cachectization, ascites, and repeated ileus conditions.

DiGeorge syndrome (DGS) is a primary immunodeficiency disease characterized by multiple clinical features, including congenital heart defects, typical facial appearance, hypocalcemia, and immunodeficiency associated to thymic hypoplasia. A subset of patients with DGS may also have contemporary allergic diseases, possibly in the context of T cell dysregulation. Our work presents an unusual case of DGS in coincidence with severe allergic asthma successfully treated by humanized monoclonal anti-IgE antibody, omalizumab. Biological therapy with omalizumab is indicated as an add-on treatment for poorly controlled asthma in patients with severe persistent allergic asthma aged 6 years and above, who meet strict criteria. While data available from clinical trials suggest that omalizumab is generally well-tolerated, a little is known about its efficacy and tolerability in the context of underlying immunodeficiency. We reported for the first time that omalizumab could be safely effective in treatment of severe allergic asthma in patients with DGS, without modification of immunological parameters.
RESUMO
BACKGROUND: Laryngopharyngeal reflux (LPR) is suspected when the symptoms are attributed to the penetration of acidic gastroesophageal reflux (GER) into the larynx. However, the relationships between the intensity of LPR and symptoms and laryngeal injury have not been elucidated. Several factors confound the study of LPR, namely pH is monitored in the pharynx (pharyngeal reflux) but the pharyngeal acidity (pH) required to induce laryngeal injury is unknown, the GER origin of pharyngeal acid is not always established, and a recent treatment with proton pump inhibitors (PPI) confounds the analysis. AIMS: We aimed to limit these confounding factors to analyze the relationship between LPR and symptoms and laryngeal injury. METHODS: We used dual pharyngeal and distal esophageal 24-h pH/impedance monitoring to establish GER origin of pharyngeal reflux, we used an unbiased approach to analysis by evaluating a whole range of acidity (pH < 6, pH < 5.5, pH < 5.0, pH < 4.5 and pH < 4.0) in patients with suspected LPR without PPI for > 30 days. RESULTS: Pharyngeal reflux was (median[IQR]) 14[8-20.5] and 4[1.5-6.5] pharyngeal reflux episodes with pH < 6.0 and pH < 5.5, respectively. Pharyngeal reflux with pH < 5.0 was rare. Comprehensive analysis did not reveal any correlation between symptoms (reflux symptom index) or laryngeal injury (reflux finding score) and the number of pharyngeal reflux episodes or duration of pharyngeal acid exposure at any pH level. CONCLUSION: Unbiased comprehensive approach did not reveal any relationship between acidic pharyngeal reflux and the symptoms or laryngeal injury attributed to LPR. Limited clinical usefulness of pharyngeal monitoring reported by others is unlikely due to confounding factors.

Recent studies in animal models have reported that some afferent fibers innervating the esophagus express the cold receptor TRPM8. In the somatosensory system the stimulation of TRPM8 leads to cold sensations and in certain circumstances alleviates pain. It is therefore hypothesized in this paper that the esophageal infusion of the TRPM8 activator menthol evokes cold sensations from the esophagus and alleviates heartburn in humans. The esophageal infusion of menthol (3 mM, 20 min) evoked cold sensations in 11 of 12 healthy subjects. In striking contrast, the esophageal infusion of menthol evoked heartburn in 10 of 10 patients with gastroesophageal reflux disease (GERD). In healthy subjects the cold sensation evoked by menthol was perceived only as a minor discomfort as evaluated by the visual analog scale (VAS score 1.9 ± 0.3 on the scale 1-10). However, in patients with GERD the menthol-induced heartburn was perceived as painful (VAS score 5.6 ± 0.6, P < 0.01 compared to healthy subjects). It is concluded that the sensations evoked by esophageal infusion of menthol change from relatively nonpainful cold sensations in healthy subjects to painful heartburn sensations in patients with GERD. These qualitative and quantitative changes indicate substantial alterations in afferent signaling mediating sensations from the esophagus in patients with GERD.

Symptomatic epiphrenic diverticula are mostly treated surgically with laparoscopic diverticulectomy, myotomy and anterior fundoplication. However, in case the patient does not agree with surgical therapy or is contraindicated, there are limited ways of alternative treatment. We present a case report of a 72-year-old female patient with severe dysphagia, regurgitation, paroxysmal cough, weight loss and malnutrition who was diagnosed with achalasia and large epiphrenic diverticulum. She did not give consent to the proposed surgical treatment. Alternatively, peroral endoscopic myotomy (POEM) was carried out. In one-year follow up, we observed complete symptom resolution, significant weight gain, improvement of nutritional status and no complications. We suggest that POEM could serve as an effective and safe alternative treatment for patients with achalasia and esophageal epiphrenic diverticula.

Larva migrans cutanea is a typical skin parasitosis of tropical and subtropical regions. In Central European countries, such as Slovakia and Czech Republic, larva migrans cutanea is just an imported disease. Its clinical symptoms are characterized by formation of erythematous focus with serpiginous morphology, which is caused by migration of helminth in epidermis. The disease does not threaten the patient's life, but causes significant discomfort, especially in form of pruritus in the affected area. Thanks to growing trend of today's tourism more tourists are exposed to the harmful effects of the environment in final destinations. This leads to an increase in frequency of imported diseases, with which physicians in our latitudes may not have enough experience.

BACKGROUND: Activated factor X (factor Xa) plays an important role in regulation of platelets. The aim of this study was to test the effect of direct oral factor Xa inhibitors-rivaroxaban and apixaban-on platelet aggregation in patients with nonvalvular atrial fibrillation. PATIENTS AND METHODS: This single-center pilot study enrolled 21 factor Xa inhibitors-treated (9 rivaroxaban-treated and 12 apixaban-treated) patients with nonvalvular atrial fibrillation. The trough and peak samples of these patients were tested for adenosine diphosphate (ADP)-induced, epinephrine-induced, and collagen-induced platelet aggregation with light transmission aggregometry, and with factor Xa-calibrated anti-Xa chromogenic analysis. RESULTS: The detected trough anti-Xa activity was 57.5 ± 43.4 µg/L. There was a significant increase in peak anti-Xa activity to 175.9 ± 119.6 µg/L (P < 0.001) observed. The platelet aggregation was reduced with reduced inductor concentration. However, no significant changes in ADP-induced, or in epinephrine-induced, or in collagen-induced platelet aggregation were seen comparing trough and peak sample. There were no significant differences in anti-Xa activity or in platelet aggregation comparing rivaroxaban-treated and apixaban-treated patients. CONCLUSIONS: This study showed that factor Xa inhibition does not affect ADP-induced, epinephrine-induced, and collagen-induced platelet aggregation.

The composition and function of human milk is unique and gives a basis for the development of modern artificial milk formulas that can provide an appropriate substitute for non-breastfed infants. Although human milk is not fully substitutable, modern milk formulas are attempting to mimic human milk and partially substitute its complex biological positive effects on infants. Besides the immunomodulatory factors from human milk, research has been focused on the composition and structure of human milk fat with a high content of ß-palmitic acid (sn-2 palmitic acid, ß-palmitate). According to the available studies, increasing the content of ß-palmitate added to milk formulas promotes several beneficial physiological functions. ß-palmitate positively influences fatty acid metabolism, increases calcium absorption, improves bone matrix quality and the stool consistency, and has a positive effect on the development of the intestinal microbiome.

PURPOSE: The aim of our study was to evaluate the utility of the sleep clinical record (SCR) in the follow-up of children with obstructive sleep apnea (OSA) after treatment. METHODS: SCR was completed and overnight polysomnography (PSG) was performed in all enrolled children (T0), with SCR considered positive for scores ≥6.5, as previously validated. Patients underwent adenotonsillectomy (T&A), rapid maxillary expansion (RME), and medical therapy according to severity of OSA and clinical features. Six months after completing therapy, the second overnight PSG and SCR (T1) were performed. RESULTS: For all subjects, both Apnea-Hypopnea Index (AHI) and total SCR score decreased significantly (<0.005) from T0 to T1. For SCR items, clinical examination (item 1) and reported sleep respiratory symptoms (item 2) ameliorated significantly (<0.005). However, hyperactivity or inattention (item 3) decreased significantly (<0.005) after treatment only in T&A group, while no differences in AHI and SCR scores occurred in the medically treated group. At T1, SCR was positive in 95.6 % of children with AHI ≥1, with a concordance of 100 % in the T&A and RME groups, resulting in a positive predictive value of 100 %. A poor concordance (38.3 % in T&A group and 53.4 % in RME group) was found when SCR < 6.5. Children with SCR ≥ 6.5 at T1 showed higher AHI compared to patients with SCR < 6.5 (5.7 ± 5.9 ev/h vs 1.78 ± 1.76 ev/h; p < 0.005). CONCLUSIONS: SCR emerges as a potentially useful instrument for follow-up of children with OSA after treatment.
