Natural history of asymptomatic gallbladder stones in clinic without beds:A long-term prognosis over 10 years

BACKGROUND Several studies have explored the long-term prognosis of patients with asymp-tomatic gallbladder stones.These reports were primarily conducted in facilities equipped with beds for addressing symptomatic cases.AIM To report the long-term prognosis of patients with asymptomatic gallbladder stones in clinics without bed facilities.METHODS We investigated the prognoses of 237 patients diagnosed with asymptomatic gallbladder stones in clinics without beds between March 2010 and October 2022.When symptoms developed,patients were transferred to hospitals where appropriate treatment was possible.We investigated the asymptomatic and survival periods during the follow-up.RESULTS Among the 237 patients,214(90.3%)remained asymptomatic,with a mean asymptomatic period of 3898.9279±46.871 d(50-4111 d,10.7 years on average).Biliary complications developed in 23 patients(9.7%),with a mean survival period of 4010.0285±31.2788 d(53-4112 d,10.9 years on average).No patient died of biliary complications.CONCLUSION The long-term prognosis of asymptomatic gallbladder stones in clinics without beds was favorable.When the condition became symptomatic,the patients were transferred to hospitals with beds that could address it;thus,no deaths related to biliary complications were reported.This finding suggests that follow-up care in clinics without beds is possible.

Clinical profile and risk factors of symptomatic and asymptomatic hypoglycemia in neonates admitted to NICU in a tertiary care center: A cross-sectional study

Objective:To investigate the clinical profile and risk factors of symptomatic and asymptomatic hypoglycemia in neonates admitted to a neonatal intensive care unit in a tertiary care center.Methods:The prospective observational study was conducted in a tertiary care center in the Specialty Department of Pediatric.196 Newborn babies with blood glucose levels<45 mg/dL were examined with a simple random sampling method between December 2019 and November 2021.Maternal and neonatal risk factors and clinical signs were recorded and compared between symptomatic and asymptomatic cases.Results:The proportion of symptomatic hypoglycemia neonates born to gestational diabetes mellitus mothers was significantly higher(23.4%vs.8.4%)(P<0.05).Small for gestational age,low birth weight,respiratory distress syndrome,hypothermia,and endocrine disorders were risk factors.The death rate in asymptomatic hypoglycemia neonates was significantly higher(58%vs.39%)(P<0.05).Conclusions:The study indicates that maternal gestational diabetes mellitus is associated with symptomatic hypoglycemia and asymptomatic hypoglycemia is associated with neonatal mortality.It is important to take vigilance and timely interventions to address associated symptoms,particularly poor feeding,in the management of neonatal hypoglycemia.

Implication of Oxidative Stress and Antioxidant Defence Systems in Symptomatic and Asymptomatic Plasmodium falciparum Malaria Infection among Children Aged 1 to 15 Years in the Mount Cameroon Area

It is known that the pathogenicity of Plasmodium induces the breakdown of haemoglobin, which leads to the induction of oxidative stress. This study aimed to identify the possible effects of oxidative stress and antioxidant defence systems in symptomatic and asymptomatic Plasmodium falciparum malaria infection in children (1 - 15 years old) in the Mount Cameroon vicinity. This cross-sectional study involved blood samples collected from 473 children and examined for malaria parasitaemia. Full blood counts were performed using an automated haemoanalyser. Serum oxidative stress status (malondialdehyde (MDA), nitric oxide (NO), reduced glutathione (GSH), catalase (CAT), superoxide dismutase (SOD) and vitamin C (Vit C)) were each determined by colorimetric enzymatic assays. The prevalence of malaria parasite infection was 32.1% among the participants. Out of that, 62.5% of patients with parasitaemia were symptomatic. Anaemia prevalence increased significantly with parasite density. MDA levels were significantly higher in patients with malaria symptoms than in those without symptoms. A significant and positive correlation was detected between MDA (r = 0.831, P < 0.05), NO (r = 0.779, P < 0.05), and malaria parasite density while, a significant and negative relationship occurred between parasite density and GSH (r = ?0.763, P < 0.05) and Vit C (r = ?0.826, P < 0.05) levels, SOD (r = ?0.621, P < 0.05) and CAT (r = ?0.817, P < 0.05) activities. The SOD activity and GSH level significantly decreased (P < 0.05) with an increase in the MDA levels. These findings showed that MDA and nitric oxide levels increased both in malaria participants with or without symptoms. A similar decrease in the antioxidant defence system was observed in both symptomatic and asymptomatic patients. Therefore, there is a need to develop public health policies that encourage routine diagnosis and treatment of malaria in seemingly healthy people (asymptomatic cases), and this will play an essential role in controlling malaria in tropical countries.

Report of a case of neuromyelitis optica spectrum disease with symptomatic epilepsy

Neuromyelitis optica spectrum disorder(NMOSD)is a humoral immune-mediated inflammatory demyelinating disease of the central nervous system with an unclear pathogenesis,often associated with autoimmune diseases such as systemic lupus erythematosus and dry syndrome.The pathology of the disease shows demyelinating changes and axonal damage,and the lesions mostly involve the optic nerve and spinal cord,and the last region of the medulla oblongata,thalamus,paraventricular,and other sites with high aquaporin-4 expression can also be involved.The clinical manifestations are closely related to the location of the lesion,with common symptoms such as optic neuritis,acute myelitis,and intractable eruption,and most patients have recurrent episodes that can leave sequelae such as visual impairment and urinary and bowel disorders.However,a few patients present with less common symptoms,which can easily be missed or misdiagnosed,delaying the diagnosis and treatment of the disease.In this paper,we report the case of a middle-aged female patient with the first symptoms of optic neuritis who developed seizures after 2 months.After completing relevant tests,cerebrospinal fluid and serum anti-aquaporin-4 antibodies were positive,and NMOSD with symptomatic epilepsy was considered.Seizures did not recur after hormone therapy was given again.The purpose of this report is to improve awareness and diagnosis of NMOSD among clinicians.

PCI compared with medical therapy in elderly patients with chronic symptomatic coronary artery disease

Objective The aim of this study was to assess quality of results of elderly patients with coronary disease after medical or revascularisation therapy. Methods In this study, we enrolled 103 patients aged 75 years or older with chronic angina in which 47 patients were assigned coronary angiography and revascularisation and 56 patients with optimised medical therapy. The primary endpoint was quality of life after 6 months, as assessed by questionnaire and the presence of major adverse cardiac events (death, non fatal myocardial infarction, or hospital admission for acute coronary syndrome with or without the need for revascularisation). Results After 6 months follow up, angina severity decreased and measures of quality of life increased in both treatment groups( P <0.05 ); however, these improvements were significantly greater after revascularisation( P <0.01 ). Major adverse cardiac events occurred in 30 ( 53.6% ) of patients in the medical group and 9 ( 19.1% ) in the invasive group ( P <0.01 ).Conclusions Patients aged 75 years or older with angina benefit more from revascularisation than from optimised medical therapy in terms of symptom relief and quality of life. Therefore, these patients should be offered invasive assessment despite their high risk profile followed by revascularisation if feasible.

Symptomatic and Asymptomatic SARS-CoV-2 Infection and Follow-up of Neutralizing Antibody Levels

Objective To investigate neutralizing antibody levels in symptomatic and asymptomatic patients with coronavirus disease 2019(COVID-19)at 6 and 10 months after disease onset.Methods Blood samples were collected at three different time points from 27 asymptomatic individuals and 69 symptomatic patients infected with severe acute respiratory syndrome coronavirus 2(SARS-Co V-2).Virus-neutralizing antibody titers against SARS-CoV-2 in both groups were measured and statistically analyzed.Results The symptomatic and asymptomatic groups had higher neutralizing antibodies at 3 months and 1–2 months post polymerase chain reaction confirmation,respectively.However,neutralizing antibodies in both groups dropped significantly to lower levels at 6 months post-PCR confirmation.Conclusion Continued monitoring of symptomatic and asymptomatic individuals with COVID-19 is key to controlling the infection.

A population-based cohort study of symptomatic gallstone disease in diabetic patients

AIM:To investigate the prevalence of gallstone dis-ease(GSD) and to evaluate the risk of symptomatic GSD among diabetic patients.METHODS:The study was conducted by analyzing the National Health Research Institutes(NHRI) dataset of ambulatory care patients,inpatient claims,and the updated registry of beneficiaries from 2000 to 2008.A total of 615 532 diabetic patients without a prior history of hospital treatment or ambulatory care visits for symptomatic GSD were identified in the year 2000.Age-and gender-matched control individuals free from both GSD and diabetes from 1997 to 1999 were randomly selected from the NHIR database(n = 614 871).The incidence densities of symptomatic GSD were estimated according to the subjects' diabetic status.The distributions of age,gender,occupation,income,and residential area urbanization were compared between diabetic patients and control subjects using Cox proportion hazards models.Differences between the rates of selected comorbidities were also assessed in the two groups.RESULTS:Overall,60 734 diabetic patients and 48 116 control patients developed symptomatic GSD and underwent operations,resulting in cumulative operation rates of 9.87% and 7.83%,respectively.The age and gender distributions of both groups were similar,with a mean age of 60 years and a predominance of females.The diabetic group had a significantly higher prevalence of all comorbidities of interest.A higher incidence of symptomatic GSD was observed in females than in males in both groups.In the control group,females under the age of 64 had a significantly higher incidence of GSD than the corresponding males,but this difference was reduced with increasing age.The cumulative incidences of operations for symptomatic GSD in the diabetic and control groups were 13.06 and 9.52 cases per 1000 person-years,respectively.Diabetic men exhibited a higher incidence of operations for symptomatic GSD than did their counterparts in the control group(12.35 vs 8.75 cases per 1000 person-years).CONCLUSION:The association of diabetes with increased symptomatic GSD may provide insight to the treatment or management of diabetes in clinical settings.

Analysis of clinical manifestations of symptomatic acquired jejunoileal d i verticil la r disease

AIM: To analyze systematically our experience over 22 years with symptomatic acquired diverticular disease of the jejunum and ileum, exploring the clinical manifestations and diagnosis of this rare but life-threatening disease.METHODS: The medical records of patients with surgically confirmed symptomatic jejunoileal diverticular disease were retrospectively reviewed. Data collected included demographic data, laboratory results, clinical course (acute or chronic), preoperative diagnosis, and operative findings. Inclusion criteria were as follows: (1) surgical confirmation of jejunoileal diverticular disease and (2)exclusion of congenital diverticula (e.g. Meckel's diverticulum).RESULTS: From January 1982 to July 2004, 28 patients with a total of 29 operations met the study criteria. The male:female ratio was 14:14, and the mean age was 62.6±3.5 years. The most common manifestation was abdominal pain. In nearly half of the patients, the symptoms were chronic. Two patients died after surgery. Only four cases were correctly diagnosed prior to surgery, three by small bowel series.CONCLUSION: Symptomatic acquired small bowel diverticular disease is difficult to diagnose. It should be considered in older patients with unexplained chronic abdominal symptoms. A small bowel series may be helpful in diagnosing this potentially life-threatening disease.

Utility of routine blood tests after elective laparoscopic cholecystectomy for symptomatic gallstones

AIM To evaluate the value of blood testing after elective laparoscopic cholecystectomy and its association with procedure related complications.METHODS Charts of all patients undergoing elective laparoscopic cholecystectomy from January 2013 through December2014 were reviewed retrospectively for demographics,indication for surgery,operative course and outcome.In our institution the decision to perform postoperative blood analysis is left for the discretion of the surgeon,therefore we had the possibility to compare the results of those who had blood analyses results to those who did not.Analysis was performed to identify variables associated with the decision to perform postoperative blood tests.Subsequently a univariate and multivariate analyses was performed comparing the two cohorts.Secondary subgroup analysis was performed to identify factors associated with procedure related complications.RESULTS Five hundred and thirty-two elective laparoscopic cholecystectomies for symptomatic gallstones were performed during the study period.Sixty-four percent of the patients(n=340)had blood tests taken post operatively.Patients that had laboratory tests taken were older(P=0.006,OR=1.01),had longer surgery(P<0.001,OR=3.22)had more drains placed(P<0.001,OR=3.2)and stayed longer in the hospital(P<0.001,OR=1.2).A subgroup analysis of the patients who experienced complications revealed longer stay in the hospital(P<0.001),higher body mass index(BMI)(P=0.04,OR=1.08),increased rates of drain placement(P=0.006,OR=3.1)and higher conversion rates(P=0.01,OR=14.6).Postoperative blood tests withdrawals were not associated with complications(P=0.44).On Multivariate analysis BMI and drain placement were independently associated with complications.CONCLUSION The current study indicate that routine postoperative blood tests after elective laparoscopic cholecystectomy for symptomatic gallstones does not predict complications and may have an added benefit in diagnosis and management of cases were the surgeon encountered true technical difficulty during surgery.

Characteristics of symptomatic reflux episodes in Japanese proton pump inhibitor-refractory non-erosive reflux disease patients

AIM: To clarify the pathogenesis of gastroesophageal reflux disease symptoms in non-erosive reflux disease(NERD) patients.METHODS: Thirty-five NERD patients with persistent symptoms, despite taking rabeprazole 10 mg twice daily for at least 8 wk, were included in this study. All patients underwent 24 h combined impedance- p H on rabeprazole. The symptom index(SI) was considered to be positive if ≥ 50%, and proximal reflux episodes were determined when reflux reached 15 cm above the proximal margin of the lower esophageal sphincter.RESULTS: In 14(40%) SI-positive patients, with liquid weakly acid reflux, the occurrence rate of reflux symptoms was significantly more frequent in proximal reflux episodes(46.7%) than in distal ones(5.7%)(P < 0.001). With liquid acid reflux, there were no significant differences in the occurrence rate of reflux symptoms between proximal reflux episodes(38.5%) and distal ones(20.5%)(NS). With mixed liquid-gas weakly acid reflux, the occurrence rate of reflux symptoms in proximal reflux episodes was significantly more frequent(31.0%) than in distal reflux ones(3.3%)(P < 0.001). With mixed liquid-gas acid reflux, there were no significant differences in the occurrence rate of reflux symptoms between proximal reflux episodes(29.4%) and distal ones(14.3%)(NS).CONCLUSION: The proximal extent of weakly acidic liquid and mixed liquid-gas reflux is a major factor associated with reflux perception in SI-positive patients on proton pump inhibitor therapy.

Interleukin-6 and ratio of plasma interleukin-6/interleukin-10 as risk factors of symptomatic lumbar osteoarthritis

AIM To determine the role of cartilage oligomeric matrix protein(COMP), interleukin(IL)-6, IL-10 and ratio of IL-6/IL-10 as risk factors of symptomatic lumbar osteoarthritis(OA) in postmenopausal women with estrogen deficiency.METHODS Case-control study had been conducted in Sanglah General Hospital from October 2015 until March 2016. The blood samples were obtained and analyzed by enzyme-linked immunosorbent assay(ELISA).RESULTS From 44 pairs of samples which divided into 44 samples as case group and 44 samples as control group showed that high level of COMP in estrogen deficiency postmenopausal women were not at risk(OR = 0.7; 95%CI: 0.261-1.751; P = 0.393) for symptomatic lumbar OA(cut-off point 0.946). Estrogen deficiency in postmenopausal women with the high level of IL-6 had 2.7 times risk(OR = 2.7; 95%CI: 0.991-8.320; P = 0.033) for symptomatic lumbar OA from the low level of IL-6(cut-off point 2.264). At lower level of IL-10, there was no risk for symptomatic lumbar OA(OR = 0.6; 95%CI: 0.209-1.798; P = 0.345) than with the higher level of IL-10(cut-off point 6.049). While the high ratio of IL-6/IL-10 level in estrogen deficiency postmenopausal women gave 3.4 times risk(OR = 3.4; 95%CI: 1.204-11.787; P = 0.011)for symptomatic lumbar OA than the low ratio of IL-6/IL-10 level(cut-off point 0.364).CONCLUSION High ratio of IL-6/IL-10 plasma level was the highest risk factor for causing symptomatic lumbar OA in postmenopausal women with estrogen deficiency.

Gastrointestinal symptomatic outcomes of laparoscopic and open gastrectomy

AIM:To compare the laparoscopic and the open gastrectomy approaches for short term morbidity,length of hospital stay and also long term gastrointestinal symptoms.METHODS:Patients who have undergone gastrectomy had their medical records reviewed for demographic data,type of gastrectomy,short term morbidity,and length of hospital stay.Patients were contacted and asked to complete the Gastrointestinal Symptom Rating Scale(GSRS).The GSRS measures three domains of GI symptoms:Dyspepsia Syndrome(DS) for the foregut(best score 0,worse score 15),indigestion syndrome(IS) for the midgut(best score 0,worse score 12),and bowel dysfunction syndrome(BDS) for the hindgut(best score 0,worse score 16).Statistical analysis was done using the Mann-Whitney U-test.RESULTS:We had complete data on 32 patients:7 laparoscopic and 25 open.Of these,25 had a gastroenteric anastomosis and 6 did not.The table shows the results as medians with interquartile range.Laparoscopic gastrectomy had a better score than open gastrectomy in the DS domain(0 vs 1,P = 0.02),while gastrectomy without anastomosis had a better score than gastrectomy with anastomosis in the IS domain(0 vs 1,P = 0.05).CONCLUSION:Patients have little adverse gastroin-testinal symptoms and preserve good gastrointestinal function after undergoing any type of gastrectomy.Laparoscopic approach had better dyspepsia and foregut symptoms.Performing an anastomosis led to mild adverse midgut and indigestion

Medical management of symptomatic severe aortic stenosis in patients non-eligible for transcatheter aortic valve implantation

1 Transcatheter aortic valve implantation in symptomatic severe aortic stenosis: where do we stand? Aortic stenosis occurs in 2%-9% of patients over the age of 65, the most common cause being degenerative.^([1,2]) The preferred treatment in symptomatic severe aortic stenosis(SAS) is surgical aortic valve replacement(SAVR), but in the elderly, the surgical risk can be greater than the benefit.([3]).

Modelling the Effect of Self-Immunity and the Impacts of Asymptomatic and Symptomatic Individuals on COVID-19 Outbreak

COVID-19 is one of themost highly infectious diseases ever emerged and caused by newly discovered severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).It has already led the entire world to health and economic crisis.It has invaded the whole universe all most every way.The present study demonstrates with a nine mutually exclusive compartmental model on transmission dynamics of this pandemic disease(COVID-19),with special focus on the transmissibility of symptomatic and asymptomatic infection from susceptible individuals.Herein,the compartmental model has been investigated with mathematical analysis and computer simulations in order to understand the dynamics of COVID-19 transmission.Initially,mathematical analysis of the model has been carried out in broadly by illustrating some well-known methods including exactness,equilibrium and stability analysis in terms of basic reproduction number.We investigate the sensitivity of the model with respect to the variation of the parameters’values.Furthermore,computer simulations are performed to illustrate the results.Our analysis reveals that the death rate from coronavirus disease increases as the infection rate increases,whereas infection rate extensively decreases with the increase of quarantined individuals.The quarantined individuals also lead to increase the concentration of recovered individuals.However,the infection rate of COVID-19 increases more surprisingly as the rate of asymptomatic individuals increases than that of the symptomatic individuals.Moreover,the infection rate decreases significantly due to increase of self-immunity rate.

Guidelines for the Prevention of Symptomatic Cardiovascular Disease, Based upon the Presence of Coronary Artery Calcified Plaque—Provided by the Society for the Prevention of Symptomatic Heart Disease

Introduction: The epidemic of atherosclerotic cardiovascular disease in the Western World accounts for the majority of morbidity and mortality in adults. This disease is on the increase, and previous recommendations using “risk equations” to prescribe preventive treatment have not been successful in reducing the prevalence of cardiovascular disease. Furthermore, compliance with statin medication has been limited, with approximately 50% of individuals being non-compliant within five years. This situation is unacceptable since atherosclerosis is both preventable and reversible. Methods: The guidelines presented in this article utilize coronary artery calcium scanning as the basis for preventative therapeutic decisions and identifying the presence of asymptomatic cardiovascular disease. This radiographic technique is superior to “risk equations” in predicting future cardiovascular events. It provides a comprehensive assessment of the lifelong insults to the coronary artery vascular endothelium and the resulting inflammation. Coronary artery calcium scanning is widely available, inexpensive, safe, and reproducible. It has the major advantage of increasing treatment compliance in patients with positive coronary artery calcium scores. Results: All suggested guidelines are supported by published scientific data. Citations are provided to allow the reader to obtain further information. The authors are available for further consultation. Each guideline provides specific recommendations that the primary caregiver can discuss with the patient. Patient involvement in decision-making is strongly recommended. Both treatment costs and adverse effects are minimal. Conclusion: It is anticipated that the early identification of asymptomatic cardiovascular disease and its aggressive treatment will result in regression of subclinical atherosclerosis. Adoption of these guidelines will stop the epidemic of symptomatic heart disease and result in healthier and more satisfied patients.

Effect of 0.05% topical cyclosporine for the treatment of symptomatic subepithelial infiltrates due to adenoviral keratoconjunctivitis

Dear Sir,Iam Yonca A.Akova,MD-from the Department of Ophthalmology,Bayindir Kavaklidere Hospital,Turkey.I wrote this letter to evaluate the efficacy of 0.05%topical cyclosporine A（CsA）eye drops（Restasis Allergan,Irvine,USA）in symptomatic patients with recurrent subepithelial infiltrates（SEIs）due to adenoviral keratoconjunctivitis following steroid eye drops tapering or discontinuation.

Inhibitory Activities of Lactic Acid Bacteria against Multi-Drug Resistant Uropathogenic <i>Staphylococcus saprophyticus</i>Isolated from Symptomatic Women in Lagos, Nigeria

The uropathogenic Staphylococcus saprophyticus is reported severally to be resistant to the drugs often used empirically for treatment of urinary tract infections (UTIs). Their ability to exhibit resistance to multiple drugs is a great deal of threat to successes recorded in the management of UTIs caused by this pathogen. Lactic acid bacteria (LAB) have been demonstrated to exhibit antimicrobial activities but studies about their prospect against multi-drug resistant S. saprophyticus are quite few. This study therefore investigated activities of LAB against the multi-drug resistant S. saprophyticus recovered from urine samples of symptomatic women. The three different species of LAB (Lactobacillus fermentum BTA 62, Lactobacillus johnsonii BTA 86 and Weissella confusa BTA 40) previously isolated and identified by 16S rRNA sequencing were selected based on their history of antimicrobial activities. Their metabolites were employed in the antagonistic assays against six (6) multi-drug resistant test pathogens recovered from urine samples of symptomatic, non-pregnant women attending clinics in Lagos, Nigeria and the control (S. saprophyticus subs bovis strain DSM 18669) following standard procedures. The pathogens showed resistances to almost all the antibiotics except levofloxacin, ciprofloxacin, imipenem while the control showed resistance to three. The LAB, L. fermentum inhibited five (83.3%) of the pathogens with zone diameter of 12 - 17 mm, followed by W. confusa inhibiting three (50%) with 15 - 17 mm. Lactobacillus johnsonii on the other hand, inhibited a pathogen and the control with zones of 13 mm and 14 mm respectively. In conclusion, the extracted metabolites of LAB inhibited the growth of multi-drug resistant clinical isolates of uropathogenic S. saprophyticus and may therefore be potent alternatives to antibiotics.

Laparoscopic fenestration of pancreatic serous cystadenoma:Minimally invasive approach for symptomatic benign disease

Serous cystadenoma(SC) is a benign pancreatic cystic tumor. Surgical resection is recommended for symptomatic forms, but laparoscopic fenestration of large symptomatic macrocystic SC was not yet described in the literature. In this study, 3 female patients underwent laparoscopic fenestration for macrocystic SC(12-14 cm). Diagnosis was established via magnetic resonance imaging and endoscopic ultrasound, with intra-cystic dosage of tumors markers(ACE and CA19-9) in 2 patients. All patients were symptomatic and operated on 15-60 mo after diagnosis.Radiological evaluation showed constant cyst growth.Patients were informed about this new surgical modality that can avoid pancreatic resection. The mean operative time was 103 min(70-150 min) with one conversion.The post-operative course was marked by a grade A pancreatic fistula in one patient and was uneventful in the other two. The hospital stay was 3, 10, and 18 d, respectively. The diagnosis of macrocystic SC was histologically-confirmed in all cases. At the last followup(13-26 mo), all patients were symptom-free, and radiological evaluation showed complete disappearance of the cyst. Laparoscopic fenestration, as opposed to resection, should be considered for large symptomatic macrocystic SC, thereby avoiding pancreatic resection morbidity and mortality.

High-fibre diet and Lactobacillus paracasei B21060 in symptomatic uncomplicated diverticular disease

AIM： To investigate in symptomatic uncomplicated di- verticular disease the efficacy of symbiotics associated with a high-fibre diet on abdominal symptoms. METHODS： This study was a multicentre, 6-too ran- domized, controlled, parallel-group intervention with a preceding 4-wk washout period. Consecutive out- patients with symptomatic uncomplicated diverticular disease, aged 40-80 years, evaluated in 4 Gastroenterology Units, were enrolled. Symptomatic uncomplicated diverticular disease patients were randomized to two treatment arms A or B. Treatment A （n = 24 patients） received 1 symbiotic sachet Flortec~ （Lactobacillus paracasei B21060） once daily plus high-fibre diet for 6 mo. Treatment B （n = 21 patients） received high-fibre diet alone for 6 rno. The primary endpoint was regres- sion of abdominal symptoms and change of symptom severity after 3 and 6 mo of treatment. RESULTS： In group A, the proportion of patients with abdominal pain 〈 24 h decreased from 100% at base- line to 35% and 25% after 3 and 6 mo, respectively （P 〈 0.001）. In group B the proportion of patients with this symptom decreased from 90.5% at baseline to 61.9% and 38.1% after 3 and 6 mo, respectively （P = 0.001）. Symptom improvement became statistically sig- nificant at 3 and 6 mo in group A and B, respectively. The proportion of patients with abdominal pain 〉24 h decreased from 60% to 20% then 5% after 3 and 6 too, respectively in group A （P 〈 0.001） and from 33.3% to 9.5% at both 3 and 6 mo in group B （P = 0.03）. In group A the proportion of patients with ab- dominal bloating significantly decreased from 95% to 60% after 3 mo, and remained stable （65%） at 6-mo follow-up （P = 0.005） while in group B, no significant changes in abdominal bloating was observed （P = 0.11）. After 6 mo of treatment, the mean visual analogic scale （VAS） values of both short-lasting abdominal pain （VAS, mean ± SD, group A： 4.6 ± 2.1 vs 2.2 ± 0.8, P = 0.02; group B： 4.6 ± 2.9 vs 2.0 ± 1.9, P = 0.03） and abdom- inal bloating （VAS, mean ± SD, group A： 5.3 ± 2.2 vs 3.0 ± 1.7, P = 0.005; group B： 5.3 ±3.2 vs 2.3 ± 1.9, P = 0.006） decreased in both groups, whilst the VAS values of prolonged abdominal pain decreased in the Flortec group, but remained unchanged in the high-fibre diet group （VAS, mean ± SD, group A： 6.5 ± 1.5 vs 4.5 ± 2.1, P = 0.052; group B： 4.5 ± 3.8 vs 5.5 ± 3.5）. CONCLUSION： A high-fibre diet is effective in relievingabdominal symptoms in symptomatic uncomplicated di- verticular disease. This treatment may be implemented by combining the high-fibre diet with Flortec~.

Pars plana vitrectomy relieves the depression in patients with symptomatic vitreous floaters

AIM:To investigate the depressive state among the patients with symptomatic vitreous floaters(SVF),as well as its change after SVF removal via vitrectomy surgery.METHODS:Twenty-eight eyes of 28 patients who underwent 27-gauge pars plana vitrectomy(PPV)for SVF were included.Thirty-nine eyes of 39 age-and gendermatched healthy volunteers without SVF were also recruited as a healthy control.Center for Epidemiologic Studies Depression(CES-D)was used to assess volunteers and patients’depression(before and 1 wk after PPV).RESULTS:The CES-D score was 18.3±8.6 for patients,and was 12.4±6.0 for healthy control(P=0.003).Patients were significantly more likely to be in a depressive state(53.6%,defined as CES-D score≥16)than the healthy control(20.5%,P=0.005).For patients with SVF,the CES-D score was negatively correlated with their age(rs=-0.42,P=0.025).After PPV,both the CES-D score(11.9±5.4 vs 18.3±8.6,P<0.001)and proportion of depressive state(18.5%vs 53.6%,P=0.005)were significantly decreased.CONCLUSION:This study suggests that symptoms of vitreous floaters have an apparently negative impact on patients’psychological state.The PPV can effectively relieve the depressive state for patients with SVF.
