| 1 | Helicobacter pylori infection and gastropathy:A comparison between Indonesian and Japanese patients显示文摘AIM:To compare the effects of Helicobacter pylori(H pylori) infection on gastropathy between Indonesian and Japanese patients.METHODS:Biopsy specimens were obtained during upper gastrointestinal endoscopy from 167 subjects(125 Indonesians and 42 Japanese) with uninvestigated symptoms of dyspepsia.The specimens were analyzed for the presence of H pylori using urease analysis,histopathology,and cell culture.The grade and activity of gastritis was assessed using the updated Sydney system.RESULTS:The percentages of Indonesian and Japanese patients who were H pylori-positive at the antrum or body of the stomach were similar(68% and 59.5%,respectively;P=0.316).Of those who were H pylori-positive,more Japanese patients than Indonesian patients had high levels of polymorphonuclear cells(P=0.001),mononuclear cells(P=0.013),glandular atrophy(P=0.000),and intestinal metaplasia(P=0.011) in both the antrum and body of the stomach.CONCLUSION:The grade of gastritis and prevalence of mucosal atrophy and intestinal metaplasia were higher in Japanese patients.The difference between Indonesian and Japanese patients was signifi cant. | Murdani Abdullah Hiroyuki Ohtsuka Abdul Aziz Rani Tadashi Sato Ari F Syam Masayuki A Fujino | 2009 | World Journal of Gastroenterology2009，15，39： | 2 |
| 2 | Case series in Indonesia:B.1.617.2(delta)variant of SARS-CoV-2 infection after a second dose of vaccine显示文摘BACKGROUND The B.1.617.2(delta)variant of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)was first discovered in Maharashtra in late 2020 and has rapidly expanded across India and worldwide.It took only 2 mo for this variant to spread in Indonesia,making the country the new epicenter of the delta variant as of July 2021.Despite efforts made by accelerating massive rollouts of current vaccines to protect against infection,cases of fully-vaccinated people infected with the delta variant have been reported.AIM To describe the demographic statistics and clinical presentation of the delta variant infection after the second dose of vaccine in Indonesia.METHODS A retrospective,single-centre case series of the general consecutive population that worked or studied at Faculty of Medicine,Universitas Indonesia with confirmed Delta Variant Infection after a second dose of vaccine from 24 June and 25 June 2021.Cases were collected retrospectively based on a combination of author recall,reverse transcription-polymerase chain reaction(RT-PCR),and whole genome sequencing results from the Clinical Microbiology Laboratory,Faculty of Medicine,Universitas Indonesia.RESULTS Between 24 June and 25 June 2021,15 subjects were confirmed with the B.1.617.2(delta)variant infection after a second dose of the vaccine.Fourteen subjects were vaccinated with CoronaVac(Sinovac)and one subject with ChAdOx1 nCoV-19(Oxford-AstraZeneca).All of the subjects remained in home isolation,with fever being the most common symptom at the onset of illness(n=10,66.67%).The mean duration of symptoms was 7.73 d(±5.444).The mean time that elapsed from the first positive swab to a negative RT-PCR test for SARS-CoV-2 was 17.93 d(±6.3464).The median time that elapsed from the second dose of vaccine to the first positive swab was 87 d(interquartile range:86-128).CONCLUSION Although this case shows that after two doses of vaccine,subjects are still susceptible to the delta variant infection,currently available vaccines remain the most effective protection.They reduce clinical manifestations of COVID-19,decrease recovery time from the first positive swab to negative swab,and lower the probability of hospitalization and mortality rate compared to unvaccinated individuals. | Anis Karuniawati Ari F Syam Armand Achmadsyah Fera Ibrahim Yulia Rosa Pratiwi Sudarmono Fadilah Fadilah Menaldi Rasmin | 2022 | World Journal of Clinical Cases2022，10，36： | 0 |
| 3 | Colorectal cancer patients in a tertiary hospital in Indonesia: Prevalence of the younger population and associated factors显示文摘BACKGROUND An increasing trend in colorectal cancer(CRC)occurring at younger ages has been observed worldwide,even though incidence is declining in the general population.Most currently available guidelines still recommend CRC screening for older populations,despite an alarming rise in early-onset CRC incidence.Risk stratification is necessary to further determine the population most at risk for early-onset CRC.However,epidemiological data on related clinical characteristics and potential risk factors,especially in developing countries,have not been widely reported.AIM To investigate the prevalence,demographics,clinicopathologic features,and associated factors of young-onset CRC patients in a tertiary hospital in Indonesia.METHODS Patients undergoing colonoscopy examination between 2008 and 2019,yielding a diagnosis of CRC were identified from medical records.The subjects were classified into two groups according to their age at diagnosis,namely early-onset(18-49 years old)and late-onset(≥50-years-old).Demographic data,characteristics,and risk factors of both onset age groups were evaluated using the chisquare and Fisher’s exact test.RESULTS Among 495 CRC patients confirmed by histopathology,205(41.4%)were classified as early-onset and 290(58.6%)as late-onset.Most subjects in the earlyonset CRC group were male(53.7%),with 89.8%displaying adenocarcinoma histopathology.A majority(78%)of the early-onset CRC patients had left-sided tumors,with the rectum(41%)and rectosigmoid(17.6%)being the most common sites.Abdominal pain was the most frequent symptom in the early-onset CRC patients(55.6%),which was significantly higher than that in the late-onset CRC patients(43.8%,P<0.05).Early-onset CRC cases were more likely to be underweight(34.6%vs 20.0%,P<0.001)compared to late-onset CRC cases.The proportion of subjects with suspected hereditary nonpolyposis colorectal cancer(HNPCC)was also higher in the early-onset CRC group than in the late-onset age group(9.3%vs 4.1%,P<0.05).However,no difference was observed in the parental or family histories of CRC cases.CONCLUSION Early-onset CRC patients were more likely to have abdominal pain,underweight status,and HNPCC suspicion than late-onset CRC patients. | Dadang Makmun Marcellus Simadibrata Murdani Abdullah Ari F Syam Hamzah Shatri Achmad Fauzi KakaRenaldi Hasan Maulahela Amanda P Utari Rabbinu R Pribadi Virly N Muzellina Saskia A Nursyirwan | 2021 | World Journal of Clinical Cases2021，9，32： | 0 |
