Nickel free-diet enhances the Helicobacter pylori eradication rate: a pilot study.

BACKGROUND: The Helicobacter pylori eradication rate with standard triple therapy is very low. H. pylori is known to require the nickel-containing metalloenzymes urease and NiFe-hydrogenase to survive at the low pH environment in the stomach. AIM: To compare the H. pylori eradication rate of a nickel free-diet associated with standard triple therapy and standard triple therapy alone as the first-line regimen. METHODS: Fifty-two sex- and age-matched patients at the first diagnosis of H. pylori infection were randomized 1:1 into two different therapeutic schemes: (1) standard LCA (26 patients): lansoprazole 15 mg bid, clarithromycin 500 mg bid and amoxicillin 1,000 mg bid for 7 days with a common diet; (2) standard LCA plus a nickel free-diet (NFD-LCA) (26 patients). Patients followed 30 days of a nickel-free diet plus a week of lansoprazole 15 mg bid, clarithromycin 500 mg bid and amoxicillin 1,000 mg bid starting from day 15 of the diet. RESULTS: All patients completed the study. A significantly higher eradication rate was observed in the NFD-LCA group (22/26) versus LCA group (12/26) (p < 0.01). Only a few patients (9 of 52) reported the occurrence of mild therapy-related side effects, without any significant differences between the two groups. CONCLUSIONS: The addition of a nickel-free diet to standard triple therapy significantly increases the H. pylori eradication rate. The reduction of H. pylori urease activity due to the nickel-free diet could expose the bacterium to gastric acid and increase H. pylori's susceptibility to amoxicillin. Further studies are necessary to confirm this preliminary result.

cDNA-microarray analysis as a new tool to predict lymph node metastasis in gastric cancer.

BACKGROUND: The aim of the present study was to investigate whether microarray gene expression analysis can be used to predict lymph node status in gastric cancer. METHODS: Twenty-nine patients undergoing gastrectomy for cancer were enrolled and subdivided according to the pathologic nodal involvement of their disease (N+ vs. N0). Molecular profiling was performed by cDNA microarray on tumor tissue and healthy mucosa. Data were processed to identify differently expressed genes. Selected genes were categorized with gene ontology. RESULTS: Compared to healthy gastric mucosa, 52 genes were differently expressed in N+ patients, and 50 genes in N0 patients. Forty-five genes were similarly regulated in N+ and N0 patients, whereas 12 genes were differently expressed between N+ and N0 patients. Seven genes were exclusively expressed in N+ patients: Egr-1 was upregulated; Claudin-18, AKR1C2, Cathepsin E, CA II, TFF 1, and progastricsin were downregulated. Five genes were exclusively expressed in N0 patients: Complement C5 receptor 1, PLA2/VII, and MMP- 9 were upregulated; MAO-A and ID-4 were downregulated. CONCLUSIONS: Microarray analysis could be a valuable tool to identify genes associated with lymph node metastasis in gastric cancer. This technique could improve the selection of patients with locally advanced disease who are candidates for extended lymph node dissection, multimodal treatment options, or alternative therapeutic strategies.

Methane intestinal production and poor metabolic control in type I diabetes complicated by autonomic neuropathy.

AIM: At the state of art it's unknown the correlation between diabetes and lower gastrointestinal disorders. Some studies show a significantly higher prevalence of small intestinal bacterial overgrowth in patients with type I diabetes in particular complicated by autonomic neuropathy. No data exists about gastrointestinal methane production in patients with diabetes and autonomic diabetic neuropathy. The aim of this paper was to evaluate the correlation of small intestinal bacterial overgrowth and gastrointestinal methane production with metabolic control and daily insulin requirements in patients with type 1 diabetes and. autonomic diabetic neuropathy. METHODS: Thirty subjects with type 1 diabetes and autonomic diabetic neuropathy were underwent hydrogen and methane lactulose breath test (LBT) to evaluate the presence of small intestinal bacterial overgrowth (double peak of hydrogen) and methane production. The metabolic control was evaluated through the glycated hemoglobin and the daily insulin requirement (calculated as ratio between total insulin units in a day and body weight). Methane producers were treated with metronidazole (500 mg bid for 10 days) and perform a LBT 8 weeks after the end of therapy RESULTS: Eight over thirty patients (26.6%) met the diagnostic criteria for small intestinal bacterial overgrowth. 11/30 patients (36%) were methane-producers (mean baseline value 16.37 ± 13.01 ppm; mean peak 26.62 ± 11.41 ppm); interestingly this subset of patients showed a worse glycemic control (mean HbA1c 8.16 ± 0.9% vs. 7.49 ± 0.8%, P<0.05). After metronidazole therapy 7/11 (63.3%) reduced CH4 production and they showed a mean HbA1c significantly lower than corresponding value before antibiotic therapy (7.63 ± 0.7% vs. 8.25 ± 0.8%). CONCLUSION: Our study showed for the first time a possible role of CH4 production in metabolic control. In particular, the most interesting data is that an increased values of HbA1c seems to be related to a gut CH4 production as confirmed by its significant improvement after eradication therapy. We are not yet able to determine whether poor glycemic control is the cause or the consequence of the selection of methanogenic flora.

The prevalence of small intestinal bacterial overgrowth and methane production in patients with myelomeningocele and constipation.

STUDY DESIGN: Prospective study. OBJECTIVES: The objective of this study was to assess the prevalence of small intestinal bacterial overgrowth (SIBO), methane (CH4) production and orocecal transit time (OCTT) in children affected by myelomeningocele. SETTING: This study was conducted at the Catholic University in Rome, Italy. METHODS: Eighteen (6M/12F; 16.4±7.6 years) children affected by myelomeningocele were enrolled. All subjects underwent H2/CH4 lactulose breath tests to assess SIBO and OCTT. All patients performed a visual analog scale to investigate abdominal pain, bloating and flatulence, and maintained a diary of the frequency and consistency of the stool during the previous 7 days. A nephro-urological clinical evaluation of the number of urinary tract infections (UTIs) and neurogenic bowel disease score were also performed. RESULTS: Thirty-nine percent (7/18) of the children showed SIBO and 61% (11/18) presented a delayed OCTT. Moreover 44.4% (8/18) produced high levels of CH4. Interestingly, all myelomeningocele children who produced CH4 showed a delayed OCTT and a higher incidence of UTI, with a lower frequency of evacuation, compared with those with a normal or accelerated OCTT. CONCLUSION: The association between CH4 and constipation suggests that CH4 has an active role in the development of constipation. One of the most interesting features of our study is to identify a correlation between myelomeningocele, CH4, delayed OCTT and UTI. The intestinal decontamination with locally acting drugs in these children may reduce the number of UTIs and improve intestinal motility.

The role of intestinal microbiota and the immune system.

BACKGROUND: The human gut is an ecosystem consisting of a great number of commensal bacteria living in symbiosis with the host. Several data confirm that gut microbiota is engaged in a dynamic interaction with the intestinal innate and adaptive immune system, affecting different aspects of its development and function. AIM: To review the immunological functions of gut microbiota and improve knowledge of its therapeutic implications for several intestinal and extra-intestinal diseases associated to dysregulation of the immune system. METHODS: Significant articles were identified by literature search and selected based on content, including atopic diseases, inflammatory bowel diseases and treatment of these conditions with probiotics. RESULTS: Accumulating evidence indicates that intestinal microflora has protective, metabolic, trophic and immunological functions and is able to establish a "cross-talk" with the immune component of mucosal immunity, comprising cellular and soluble elements. When one or more steps in this fine interaction fail, autoimmune or auto-inflammatory diseases may occur. Furthermore, it results from the data that probiotics, used for the treatment of the diseases caused by the dysregulation of the immune system, can have a beneficial effect by different mechanisms. CONCLUSIONS: Gut microbiota interacts with both innate and adaptive immune system, playing a pivotal role in maintenance and disruption of gut immune quiescence. A cross talk between the mucosal immune system and endogenous microflora favours a mutual growth, survival and inflammatory control of the intestinal ecosystem. Based on these evidences, probiotics can be used as an ecological therapy in the treatment of immune diseases.  

Recurrent use of the Emergency Department in patients with anxiety disorder.

OBJECTIVE: Panic disorder is characterized by the spontaneous and unexpected occurrence of panic attacks. During panic attacks, patients (pts) refer to the Emergency Department (ED). The diagnostic work-up for any panic attack is expensive since symptoms at presentation mimic other diseases such acute coronary syndrome or neurological emergencies. The aim of the present study was to describe a 10 years cohort of pts diagnosed with panic disorder in the ED in terms of ED visit recurrence. METHODS: Case-control study, in a tertiary care, involving pts presenting to the ED and diagnosed with panic attack according to the International Classification of Diseases 9nt Revision (ICD-9). From January 2001 to Dec 2009 were extracted from the electronic clinical database 469 pts and were divided into "recurrent ED visit" (multiple ED access for panic attack) (N=361) and "no recurrent ED visit" (only one ED access for panic attack in 9 years) (N=108). RESULTS: At univariate analysis cases and controls differed for male prevalence (p < 0.01), neurological symptoms at presentation (p = 0.02) and history of other psychiatry disorder (p < 0.01). In multivariate analysis independent predictors were male gender, age under 40 year old, palpitations at presentations, 1 or more cardiovascular risk factors and previous other psychiatry conditions. CONCLUSIONS: Male under 40 years old with palpitations or cardiovascular risk and other psychiatric diseases, have a higher recurrence of panic attacks. General psychiatric evaluation and treatment with benzodiazepine in ED is not useful to prevent recurrences. Identifying those patients at high risk of panic attack and ED visit recurrence might be useful to establish ad-hoc interventions, improve patients' morbidity and save precious resources.

Rifaximin treatment for small intestinal bacterial overgrowth in children with irritable bowel syndrome.

OBJECTIVES: Aims of the study were to assess the effects of rifaximin treatment on small intestinal bacterial overgrowth (SIBO) prevalence and gastrointestinal symptoms. STUDY DESIGN: Fifty (50) irritable bowel syndrome (IBS) children were consecutively enrolled. All subjects underwent lactulose hydrogen/methane breath test (LBT) to assess SIBO before and one month after the treatment with rifaximin 600 mg daily for one week. All IBS patients filled out a Visual Analogic Scale (VAS) to assess and score gastrointestinal symptoms (abdominal pain, constipation, diarrhoea, bloating, flatulence) at baseline and one month after treatment. RESULTS: The prevalence of abnormal LBT in patients with IBS was 66% (33/50). LBT normalization rate was 64% (21/33). Compliance was excellent, and no relevant side-effects were observed during treatment. VAS score was significantly higher in IBS patients with abnormal LBT than SIBO negatives, and strongly improved after successful treatment. CONCLUSIONS: Rifaximin was effective and safe in SIBO treatment and IBS symptoms improvement in childhood. Double blind placebo-controlled interventional studies are warranted to verify the real impact of SIBO on gastrointestinal symptoms in children with IBS.

Treatment of fever and associated symptoms in the emergency department: which drug to choose?

OBJECTIVE: Fever is a frequent cause of admission to the Emergency Department (ED) worldwide. Although it can be caused by a wide range of conditions, the most effective treatment based on its etiology is still undetermined. PATIENTS AND METHODS: This prospective, single-center, observational study enrolled adult patients who accessed the ED for fever. Physicians were free to administer paracetamol 1,000 mg (P), the combination paracetamol 500 mg/ibuprofen 150 mg (PI) or Ibuprofen 600 mg (I). The primary endpoint was both 1-degree and 1-point reduction in body temperature for all associated symptoms on the Numerical Rating Scale (NRS) after 1 hour (T1). The secondary endpoint was the reduction of at least 2 points on the NRS after two hours (T2). Adverse events, the need for rescue therapy, and the response based on the underlying etiology (bacterial, viral, or immune/neoplastic) were also evaluated. RESULTS: 324 patients (170 males, mean age 71±6 years) were enrolled: 187 had bacterial, 80 viral, and 57 neoplastic/inflammatory fever. Fever was treated with Paracetamol 1,000 mg (P) in 189 patients and with Paracetamol/Ibuprofen 500/150 mg (PI) in 135 subjects, while none of the patients were primarily treated with I. Based on the fever etiology P was administered to 113 patients with bacterial fever (59.8%), 48 patients with viral fever (25.4%), and 28 subjects with neoplastic/inflammatory fever (14.8%). PI was administered to 74 patients with bacterial fever (54.8%), 32 patients with viral fever (23.7%), and 29 subjects with neoplastic/inflammatory fever (21.5%). The primary endpoint was achieved by 126 patients, 70 of them (37.0%) were treated with P and 56 (41.5%) with PI (p=0.418). The secondary endpoint was achieved by 295 patients, 171 (90.5%) of them treated with P and 124 (91.9%) treated with PI (p=0.669). No significant differences were found between groups treated with P and PI concerning rescue therapy (15 vs. 6 patients; p=0.893). Interestingly, PI was more effective than P in patients with bacterial fever at T1 (P 33.6% vs. PI 48.6%; p=0.040), while efficacy of P and PI was similar at T2 for all kind of fever. CONCLUSIONS: Paracetamol 1,000 mg represents the first choice for the treatment of fever in the ED, followed by Paracetamol/Ibuprofen 500/150 mg. Interestingly, Paracetamol/Ibuprofen combination resulted in being more effective in patients with bacterial fever one hour after its administration.

Colitides.

OBJECTIVE: This Review provides an overview of the pathophysiology, epidemiology, histopathology, clinical characteristics of non-IBD forms of colitis over than some preliminary therapeutic evidences. STATE OF THE ART: The term "Colitides" includes a variety of inflammatory diseases of the colon. These forms of colitis occur as either primary conditions or complications of other diseases. The etiopathogenesis of most of them remains obscure and the epidemiological data are rather limited. Clinical presentations include chronic, watery diarrhea, abdominal pain and intermittent rectal bleeding. Endoscopic evaluation and mucosal biopsy are essential to confirm the diagnosis and to exclude IBD-associated colitis. These diseases include microscopic colitis, ischemic colitis, segmental colitis associated with diverticula, radiation colitis, diversion colitis, eosinophilic colitis and Behcet's colitis. TREATMENT: In many cases the treatment is empirical and often the therapy and outcome depend on the severity of the disease.

Patient safety recommendations and management in patients with COVID-19 pneumonia suspicion: a retrospective study.

OBJECTIVE: Since December 2019, new pneumonia of unknown aetiology broke out in Wuhan, Hubei province, China. Subsequently, a virus, later named as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was identified as the causative agent of the disease. Currently, the epidemic has spread all over the world. The most common manifestations of COVID-19 are fever, fatigue and dry cough. At the moment, the nuclide acid test is the gold standard method for the diagnosis of this infection. METHODS: In the present paper, we report our experience with all patients who came to the Emergency Department from March 1 to April 1, 2020, with suggestive symptoms of COVID-19 infection. Patients: they all underwent a first oropharyngeal and nasopharyngeal swab in the emergency department and, if negative, a second one after at least 24 hours. RESULTS: Our study shows how the results obtained at time zero are usually identical to the ones obtained after 24 hours. We thus suggest, in patients with high suspicion of COVID19 and a negative result at the first swab, to repeat the test after at least 48 hours, during which patients with symptoms of COVID-19 pneumonia disease should be kept in isolation to avoid the risk of contagion. CONCLUSIONS: these measures and in particular the early identifica-tion of cases with consequent isolation will allow the containment of the spread of the virus, representing one of the fundamental measures to guarantee and strengthen the control of the infection to reduce hospital admissions, the overload of national health service and health costs.

13C urea breath test to identify Helicobacter pylori Infection in patients with upper gastrointestinal bleeding admitted to the Emergency Department.

OBJECTIVE: Upper gastrointestinal bleeding (UGIB) is a cause of Emergency Department (ED) visits. Peptic ulcer secondary to H. pylori (HP) infection and/or to the use of NSAIDs is the most frequent cause. The aim of the study is to evaluate directly in the ED the prevalence of HP infection through Urea Breath test (UBT) in patients admitted to the ED for UGIB. PATIENTS AND METHODS: We enrolled 87 patients (58M/29F) with a mean age of 63.8 + 11.7 yrs with an active UGIB who performed EGDS and UBT. RESULTS: 34.4% of patients performing EGDS and UBT resulted positive to HP. Peptic ulcer was present in 20/30 (66.7%) of HP+ compared to 20/57 (35.1%) of HP- (p<0.001), and also gastritis and/or duodenitis were mostly present in HP+ (23.3% vs. 15.8%) (p<0.05). A biopsy was performed in only 31% of patients with a positive rate of 33.3%. In 78% we obtained a correspondence between UBT and biopsy results. Compared to biopsy result, we obtained for UBT a positive predictive value (PPV) of 71% and a negative predictive value (NPV) of 80%. Taking the UBT as a gold standard, we obtained for biopsies a PPV of 69% and a NPV of 85%. CONCLUSIONS: Our study confirms that the use of UBT directly in ED in patients with UGIB allows for a rapid, reliable and non-invasive diagnosis of HP infection as a causative agent for bleeding, thus permitting a right etiological treatment.

Changes in admissions, and hospitalization outcomes of IBD patients in an Italian tertiary referral center over a 13-year period.

OBJECTIVE: The management of Inflammatory Bowel Disease (IBD) has changed significantly in recent years, mainly due to the introduction of biologic medications, however, other factors may also have a role. The aim of this study was to evaluate the evolution of IBD admissions, including trends, modality of admission and rates of surgical intervention, in a tertiary care center. PATIENTS AND METHODS: Hospitalization of patients with a diagnosis of Crohn's disease (CD) or ulcerative colitis (UC) were identified between 2000 and 2013, using ICD-9-CM codes for IBD, from our hospital database. The following parameters were evaluated for each admission: type of admission (ordinary vs. day care service), mode of admission (elective vs. emergency care, for ordinary admissions only), admission code, surgical procedures and complication rates. Comparison between pre- and post-biologic therapy introduction years was also performed. RESULTS: Between 2000 and 2013 a total of 8834 IBD-related admissions were recorded. Hospitalizations increased linearly reaching a peak in 2006, with a downward trend in the following years. The downward trend was especially marked for patients younger than 40 years. No significant differences in hospitalization trends between CD and UC were recorded. Disease flare represented the cause of hospitalization in approximately 50% of cases. Overall, 10.8% of patients underwent surgery with no difference between the two conditions. Complications occurred in 28.7% of admissions. CONCLUSIONS: Hospitalizations for IBD patients have decreased in recent years, especially in younger patients. However, a significant proportion of patients are still admitted to complete diagnostic workup, indicating the need to better implement outpatient services. A clear reduction in surgery occurrence over time could not be observed in our study.

The effect of oral supplementation with Lactobacillus reuteri or tilactase in lactose intolerant patients: randomized trial.

BACKGROUND: Lactase enzyme supplements and probiotics with high beta-galactosidase activity may be valid treatment options for the lactose intolerance. Aim of this study was to assess whether supplementation with tilactase or Lactobacillus reuteri when compared to placebo affects hydrogen breath excretion and gastrointestinal symptoms in lactose intolerant patients during lactose breath test (H,-LBT). METHODS: Sixty lactose intolerant patients participated in the study and were randomized to three 20 patients-treatment groups: tilactase group (tilactase 15 minutes before control H2-LBT); placebo group (placebo 15 minutes before control H2-LBT); Lactobacillus reuteri group (LR) (LR b.i.d. during 10 days before control H2-LBT). The outcomes were LBT normalization rate, and influences of treatments on both mean maximum hydrogen concentration and clinical score. RESULTS: LBT normalization rate was significantly higher in tilactase and LR groups with respect to placebo. Tilactase was significantly more effective than LR in achieving LBT normalization (p <0.01). Both significant reduction of mean peak H2 excretion and improvement of the mean clinical score were observed in tilactase and LR groups after treatment with respect to placebo (p <0.0001). Tilactase was significantly more effective than LR in reducing both mean peak hydrogen excretion and mean clinical score. CONCLUSIONS: In lactose intolerants, tilactase strongly improves both LBT results and gastrointestinal symptoms after lactose ingestion with respect to placebo. Lactobacillus reuteri also is effective but lesser than tilactase. This probiotic may represent an interesting treatment option for lactose intolerance since its use is simple and its effect may last in the time after stopping administration.

Helicobacter pylori infection and diabetes.

The bacterium Helicobacter pylori (H. pylori), prime causal agent of gastroduodenal diseases, has been involved in various aspects of several extragastric manifestations. Although currently available data do not provide proof of its role in most of them, a potential relationship cannot be ruled out. In the present review, the consistency of a role of H. pylori infection in the pathogenesis of diabetes mellitus (DM) as well as in the gastric abnormalities of diabetics is analyzed and critically discussed. Several controversies emerge from the epidemiological data. The clinical consequence of H. pylori infection in terms of metabolic control seems to be low. Regarding interventional studies, the bacterial eradication rate is significantly lower in DM patients than in controls. The difference in the eradication rate observed between adults and children affected by diabetes could be due to the fact that the latter have no history of repeated infectious diseases and antibiotic treatments, with minor antibiotic-resistant H. pylori strain selection. Finally, a higher H. pylori re-infection rate in DM patients than in general population has been shown.

Unexpected macrophage activation syndrome in a healthy young woman: a case report.

Macrophage activation syndrome (MAS) is a life-threatening condition and a medical emergency with a high-risk of mortality. It belongs to a group of diseases known as "hemophagocytic lymphohistiocytosis", characterized by a cytokine storm, with secretion of tumor necrosis factor, interleukins and interferon-gamma, and an inappropriate activation of macrophages and T-lymphocytes. Some inflammatory and systemic autoimmune diseases, such as systemic juvenile idiopathic arthritis, Still's disease and systemic lupus erythematosus, can develop into macrophage activation syndrome. This is the first episode of macrophage activation syndrome (MAS) in a young healthy woman. She arrived at the Emergency Department complaining of four days of weakness and fever not responsive to paracetamol. She had no significant past medical history, her mother suffered from rheumatoid arthritis. In the Emergency Department, we performed laboratory exams, autoimmune and infectious disease screening, bone marrow biopsy. The final diagnosis was of macrophage activation syndrome. Macrophage activation syndrome, in extremely rare cases, can arise independently years before the manifestation of an autoimmune disease. Persistent fever, high level of inflammatory markers and pancytopenia should raise suspicion in healthy people, especially when associated with a family history of autoimmune disease. Early diagnosis and consequent early treatment are fundamental to avoid progressive tissue damage that can lead to organ failure and death.

The role of gut microbiota in mediating obesity and diabetes mellitus.

OBJECTIVE: This review inspects the relations between the microbiota and the intestinal immune system in the advancement of metabolic illnesses, such as obesity and diabetes mellitus. The role of the microbiota in intestinal immune defense and the control of metabolism are subject to examination. MATERIALS AND METHODS: In type 1 diabetes, the adhesion proteins prompt inside the intestinal epithelium prompt a more significant immune response that may result in the destruction of pancreatic ß cells by CD8+ T-lymphocytes, as well as increased articulation of interleukin-17, which is associated with autoimmunity. Studies suggest that the beginning of metabolic ailments and certain co-morbidities can be viewed in light of the protection between the gut microbiota and the intestinal immune system. The gut microbiota is analyzed as a key regulator of metabolic ailments. Research demonstrates that obese patients with type 2 diabetes have a certain gut microbiota and that the microbiota is translocated from the gut to the tissues in conjunction with the illness, which instigates inflammation. RESULTS: Research in animals and people suggests that a probiotic supplement may regulate the gut microbiota, thereby improving the prognosis for diabetes. CONCLUSIONS: The mechanism underlying this phenomenon relates to a decrease in the inflammatory reaction and oxidative stress, as well as a decrease in leaky gut. Such reactions increase insulin sensitivity and reduce autoimmune responses.

Role of troponin in COVID-19 pandemic: a review of literature.

Acute SARS-CoV-2 respiratory disease is an infectious respiratory disease caused by the virus SARS-CoV-2 belonging to the coronaviridae family. A pandemic is still present as of May 2020. In addition to causing pneumonia, SARS-CoV-2 may induce a direct damage to the heart, causing myocarditis, with significant impairment of cardiac contractility, and/or pericarditis. Elderly patients and those with cardiovascular risk factors, such as hypertension and diabetes mellitus, are at increased risk of heart complications from COVID-19. In this review, we focused on the correlation between COVID-19 infection and the high sensitivity troponin T and I, and their significance in the development of myocarditis. Data emerging from the studies so far conducted indicate that a high value of high-sensitivity troponin represents a negative prognostic indicator when associated with heart damage on an infectious-inflammatory basis (i.e. myopericarditis). We should identify a safe and clear diagnostic algorithm, possibly combining patient clinical history, troponin levels and cardiac ultrasound findings that could help us in the prediction of myopericarditis.

Acute uncomplicated diverticulitis: key points for early management. A single-centre retrospective study.

OBJECTIVE: Acute uncomplicated diverticulitis is an important clinical condition usually managed in clinical practice with antibiotic therapies and hospitalization in ward. In this setting, recent papers and guidelines suggest to limit the use of antibiotics in selected cases and encourage an early discharge in low-risk patients. The purpose of this retrospective study is to identify serological inflammatory markers and CT findings of acute uncomplicated diverticulitis (AUD) at the onset of the disease and the correlation with the need for in-patient or out-patient management. PATIENTS AND METHODS: It was used a database drawn from the collection of the patients admitted to our Emergency Room from January 2016 to 2019 and undergoing urgent abdominal CT-scan for suspicious of acute diverticulitis. For each patient we considered biochemical and radiological parameters at the onset of the disease and if patients were managed as in-patients (hospitalization in ward) or as out-patient (early discharged or after observation in Short Stay Unit). RESULTS: Among patients with early diagnosis of AUD, 108 (65%) were hospitalized in ward with mean time of in-stay of 6.94 days, while only 58 (35%) patients with same diagnosis were managed as out-patient and early discharged from emergency room or after observation in short stay unit with a mean time of in-stay significantly shorter (3.39 days, p-value 0.0007). Higher levels of C reactive protein and the length of colon involved considered as percentage (%) in comparison with the entire colon were significantly related to the need for hospitalization (p-value 0.03). CONCLUSIONS: Biochemical parameters and a more advanced radiological evaluation, as the length (%) of colon involved, could allow a stratification of patients with diagnosis of AUD at the admission and help physicians in the early management.

Role of first aid in the management of acute alcohol intoxication: a narrative review.

OBJECTIVE: Acute alcohol intoxication is actually a common admission cause in the Emergency Department and represents an increasing public health burden, in particular among adolescents. It involves possible and significant illness and injury, which can quickly get worse and may need to be managed in the emergency room. MATERIALS AND METHODS: We conducted a narrative review of the literature regarding the effectiveness of first aid role of the Emergency Department setting. RESULTS: This review included eighteen studies about alcohol intoxication management in the Emergency Department; most of all highlights the emerging phenomenon in Europe and around the world of acute alcohol intoxication management in first aid. The treatment of acute alcohol intoxication depends on general clinical conditions of the patient, vital signs, hemodynamic stability, cognitive state, alcohol-related complications, which are closely related to the blood alcohol concentration. At the same time, symptoms could be extremely variable due to individual differences in alcohol metabolism. In case of mild-moderate intoxication (blood alcohol concentration < 1 g/L), no drugs are necessary. In case of severe intoxication (blood alcohol concentration > 1 g/L), it is necessary to support with intravenous fluids, treat hypoglycemia, hypotension, hypothermia and electrolyte imbalance, administer complex B and C vitamins and accelerate alcohol elimination from blood with metadoxine. Unlike adults, adolescents are more exposed to the toxic effect of alcohol (because of their immature hepatic alcohol dehydrogenase activity), and then, acute alcohol-related complications are more frequent and dangerous in young people than in adult population. In many cases, patients affected by acute alcohol intoxication referring to an Emergency Department have mild-moderate transitory symptoms that do not require the use of drugs; they can benefit from a clinical observation, with a clinical course often completed within 24 hours with a favorable outcome. Clinical observation with vital signs control is necessary also to evaluate the possible development of the alcohol withdrawal syndrome (that involves a specific treatment) and to evaluate also possible pathological complications of the organism, above all acute liver damage. CONCLUSIONS: Patients affected by acute alcohol intoxication are the best candidates to apply the rules of the Temporary Observation Unit in the Emergency Department, because of a clinical course often completed within 24 hours, a favorable outcome and without the need for hospitalization. In many cases, hospitalization could be not necessary, but the patient affected by Alcohol Use Disorder must be referred to an Alcohol Addiction Unit for the follow-up, to reduce the risk of alcohol relapse and complications related to alcohol abuse, and financial costs of hospitalization.

Atypical presentation of acute pancreatitis: a single center case-match analysis of clinical outcomes.

OBJECTIVE: Acute pancreatitis (AP) may present an aspecific clinical picture without abdominal symptoms (atypical AP). We compared clinical outcomes between typical and atypical AP. PATIENTS AND METHODS: Thirty out of 1163 patients (2.6%) presented an atypical AP. Demographic, clinical data, laboratory and radiological findings, management type, length of hospital stay (LOS) and mortality rate were retrospectively reviewed. A case match analysis 2:1 was performed. The final groups comprised 50 typical APs (TAP group) and 25 atypical APs (AAP group). RESULTS: The AAP patients presented fever (36%), syncope (32%) and dyspnea (16%) as the most frequent symptoms. Laboratory values showed similarity between the two groups. We noted a comparable edematous AP rate in both groups (p=0.36). Ten (20%) TAP and 3 (12%) AAP patients needed ERCP, respectively (p=0.38). Cholecystectomy was similarly performed in both cohorts (p=0.81). One TAP patient underwent a percutaneous drainage and subsequent surgical necrosectomy compared to none in the AAP cohort (p=0.47). LOS and mortality rate were comparable (p=0.76 and 0.3, respectively). CONCLUSIONS: Similar outcomes have been reached in the two groups. Routine evaluation of the serum amylase values fundamentally contributed to early diagnosis and appropriate treatment.
