Abstract
IMPORTANCE Extubation failure (EF) after pediatric cardiac surgery is associated with increased morbidity and mortality. OBJECTIVES We sought to describe the risk factors associated with early (< 48 hr) and late (48 hr ≤ 168 hr) EF after pediatric cardiac surgery and the clinical implications of these two types of EF. DESIGN SETTING AND PARTICIPANTS Retrospective cohort study using prospectively collected clinical data for the Pediatric Cardiac Critical Care Consortium (PC4) Registry. Pediatric patients undergoing Society of Thoracic Surgeons benchmark operation or heart transplant between 2013 and 2018 available in the PC4 Registry were included. MAIN OUTCOMES AND MEASURES We analyzed demographics and risk factors associated with EFs (primary outcome) including by type of surgery. We identified potentially modifiable risk factors. Clinical outcomes of mortality and length of stay (LOS) were reported. RESULTS Overall 18,278 extubations were analyzed. Unplanned extubations were excluded from the analysis. The rate of early EF was 5.2% (948) and late EF was 2.5% (461). Cardiopulmonary bypass time, ventilator duration, airway anomaly, genetic abnormalities, pleural effusion, and diaphragm paralysis contributed to both early and late EF. Extubation during day remote from shift change and nasotracheal route of initial intubation was associated with decreased risk of early EF. Extubation in the operating room was associated with an increased risk of early EF but with decreased risk of late EF. Across all operations except arterial switch, EF portrayed an increased burden of LOS and mortality. CONCLUSION AND RELEVANCE Both early and late EF are associated with significant increase in LOS and mortality. Study provides potential benchmarking data by type of surgery. Modifiable risk factors such as route of intubation, time of extubation as well as treatment of potential contributors such as diaphragm paralysis or pleural effusion can serve as focus areas for reducing EFs.

Bivalirudin or heparin for systemic anticoagulation during pediatric extracorporeal membrane oxygenation: Multicenter retrospective study. Thromb Res 2023; 229:178-186. [PMID: 37517208 DOI: 10.1016/j.thromres.2023.07.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 03/23/2023] [Accepted: 07/19/2023] [Indexed: 08/01/2023]
Abstract
BACKGROUND The objective of this study is to evaluate the outcomes of unfractionated heparin (UFH) compared to bivalirudin anticoagulation in pediatric ExtraCorporeal Membrane Oxygenation (ECMO). METHODS A multicenter retrospective study, that included pediatric patients <18 years of age, who were supported on ECMO between June 2017 and May 2020. Patients treated with UFH were matched 2:1 by age and type of ECMO support to the bivalirudin group. RESULTS The bivalirudin group (75 patients) were matched to 150 patients treated with UFH. Baseline characteristics and comorbidities of the two groups were similar. Veno-Arterial ECMO was the most common mode (141/225 [63 %]) followed by extracorporeal cardiopulmonary resuscitation (48/225 [21 %]). Bivalirudin treatment was associated with lower odds of bleeding events (aOR 0.23, 95%CI 0.12-0.45, p < 0.001) and lower odds of thrombotic events (aOR 0.48, 95%CI 0.23-0.98, p = 0.045). Patients who received bivalirudin had lesser odds for transfusion with fresh frozen plasma, and platelets (aOR 0.26, CI 0.12-0.57, p ≤0.001 and aOR 0.28, CI 0.15-0.53, p < 0.001, respectively). After adjusting for the type of ECMO support and adjusting for age, bivalirudin was associated with a decrease in hospital mortality by 50 % compared to the UFH group (aOR 0.50, 95%CI 0.27-0.93, p = 0.028). Similarly, for neurological disability at time of discharge, bivalirudin was associated with higher odds of intact neurological outcomes compared to UFH (OR 1.99 [95%CI 1.13-3.51], p = 0.017). CONCLUSIONS This study demonstrated that effective anticoagulation can be achieved with bivalirudin, which was associated with lesser odds of bleeding events and utilization of blood products. Bivalirudin, in comparison with UFH, was associated with greater odds of hospital survival and intact neurological function at the time of discharge. A prospective randomized trial is required to validate the results of this study.

Abstract
BACKGROUND Complementary and alternative medicine (CAM) is a popular alternative to opioid and other analgesics in sickle cell disease (SCD). We review the effectiveness, prevalence, and factors associated with CAM use in the pediatric SCD population. METHODS The review protocol was created based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A literature search was conducted in MEDLINE, Embase, Cochrane Library, PubMed, and Web of Science. RESULTS Twenty-four studies were examined. The prevalence of CAM use in pediatric patients with SCD ranged from 36 to 84.5%. Common inpatient CAM interventions were yoga, virtual reality, and acupuncture, which decreased pain scale scores. Outpatient CAMs were consisted of cognitive behavioral therapy, massage therapy, and guided-imagery, which increased pain tolerability and decreased pain scale scores. CONCLUSIONS CAM modalities can decrease pain scale scores. However, the impact of specific CAM modalities on emergency department visits, hospitalizations, and school absences were inconclusive.

Survival outcomes of in-hospital cardiac arrest in pediatric patients in the USA. Eur J Pediatr 2021; 180:2513-2520. [PMID: 33899153 DOI: 10.1007/s00431-021-04082-3] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/17/2021] [Revised: 04/12/2021] [Accepted: 04/14/2021] [Indexed: 01/11/2023]
Abstract
We report on in-hospital cardiac arrest outcomes in the USA. The data were obtained from the National (Nationwide) Inpatient Sample datasets for the years 2000-2017, which includes data from participating hospitals in 47 US states and the District of Columbia. We included pediatric patients (< 18 years of age) with cardiac arrest, and we excluded patients with no cardiopulmonary resuscitation during the hospitalization. Primary outcome of the study was in-hospital mortality after cardiac arrest. A multivariable logistic regression was performed to identify factors associated with survival. A total of 20,654 patients were identified, and 8226 (39.82%) patients survived to discharge. The median length of stay and cost of hospitalization were significantly higher in the survivors vs. non-survivors (LOS 18 days vs. 1 day, and cost $187,434 vs. $45,811, respectively, p < 0.001). In a multivariable model, patients admitted to teaching hospitals, elective admissions, and those admitted on weekdays had higher survival (aOR=1.19, CI: 1.06-1.33; aOR=2.65, CI: 2.37-2.97; and aOR=1.17, CI: 1.07-1.27, respectively). There was no difference in mortality between patients with extracorporeal cardiopulmonary resuscitation (E-CPR) and those with conventional cardiopulmonary resuscitation. E-CPR patients were likely to have congenital heart surgery (51.0% vs. 20.8%).Conclusion: We highlighted the survival predictors in these events, which can guide future studies aimed at improving outcomes in pediatric cardiac arrest. What is Known: • In-hospital cardiac arrest occurs in 2-6% of pediatric intensive care admissions. • Cardiac arrests had a significant impact on hospital resources and a significantly high mortality rate. What is New: • Factors associated with higher survival rates in patients with cardiac arrest: admission to teaching hospitals, elective admissions, and week-day admissions. • The use of rescue extracorporeal cardiopulmonary resuscitation in refractory cardiac arrest has increased by threefold over the last two decades.

Abstract
The present study aimed to investigate the effect of silver catfish (Pangasius sp.) protein
hydrolysate (SCPH) on physicochemical properties and oxidative stability of emulsion
sausage prepared from shortfin scad (Decapterus macrosoma). The SCPH with different
concentrations (1, 2, and 3%) was added into fish emulsion sausage followed by
characterization of its physicochemical properties. The results obtained from this study
revealed that the fish emulsion sausages contain high moisture content (63.49-66.85%),
protein content (18.04-21.89%), fat content (7.16-8.59%), carbohydrate content (2.28-
2.72%) and low ash contents (1.83-2.17%). The addition of SCPH improvised the
hardness, cohesiveness, chewiness and resilience of the emulsion sausage (p<0.05)
compared to the control sample. The finer fat globules were visualized in the sample
added with SCPH at higher concentration of 3% (10-20 µm) compared to other
concentrations (1 and 2%). Besides, the incorporation of SCPH at all concentrations
shows a significant difference on L*, a* and b* values of the emulsion sausages during
extended storage of 12 days (p<0.05). The SCPH was shown to retard lipid oxidation of
sausage after extended storage of 12 days, with lower PV and TBARS values. Therefore,
the effectiveness in retarding lipid oxidation achieved with the higher concentration of
SCPH and it also capable to retain textural properties of fish emulsion sausage in the
refrigerated storage of 12 days. Thus, as an alternative antioxidant in fish emulsion
sausage, SCPH showed a potential to be used as it improved the physicochemical
properties and oxidative stability of fish emulsion sausage.

Abstract
Introduction: Quality and safety is an important challenge in healthcare systems all over the world particularly in developing parts.
Objective: This survey aimed to assess patient safety culture (PSC) in emergency departments (EDs) in Yemen and identify its associated factors.
Methods: A questionnaire containing the Hospital Survey on Patient Safety Culture (HSOPSC) was distributed to ED physicians, nurses, and clinical, and non-clinical staff at three public teaching general hospitals. The percentages of positive responses on the 12 patient safety dimensions and the summation of PSC and two outcomes (overall patient safety grade and adverse events reported in the past year) were assessed. Factors associated with PSC aggregate score were analyzed.
Results: finally, out of 400 questionnaires, 250 (64%) were analyzed. In total, 207 (82.3%) participants were nurses and physicians; 140 (56.0%) were male; 134 (53.6%) were less than 30 years old; and 134 (53.6%) had a university degree. Participants provided the highest ratings for the “teamwork within units” PSC composite (67%). The lowest rating was for “non-punitive response to error” (21.3%). A total of 120 (48.1%) participants did not report any events in the past year and 99 (39.7%) gave their hospital an “excellent/very good” overall patient safety grade. There were significant differences between the hospitals’ EDs in the rating of “handoffs and transitions” (p=0.016), “teamwork within units” (p=0.018), and “frequency of adverse events reported” (p=0.016). Staff working in intensive care units (8.4%, n=21) had lower patient safety aggregate scores.
Conclusions: PSC ratings appear to be low in Yemen. This study emphasizes the need to create and maintain a PSC in EDs through the implementation of quality improvement strategies and environment of transparency, open communications, and continuous learning.

Abstract
Children affected with acute myocarditis may progress rapidly into profound ventricular dysfunction and ventricular arrhythmias. The objective of this study is to assess the impact of ventricular arrhythmias on in-hospital mortality and the use of mechanical circulatory support in patients with myocarditis. Pediatric patients (age 0-18 years) admitted with myocarditis were identified from the National Inpatient Sample dataset for the years 2002-2015. A total of 12,489 patients with myocarditis were identified. Of them, 1627 patients were with ventricular arrhythmias and 10,862 patients without ventricular arrhythmias. Mortality was higher in those with ventricular arrhythmias (19.5% vs. 2.8%, OR = 8.47; 95% CI 7.16-10.04; p < 0.001). The median length of stay and the median cost of hospitalization were higher in the ventricular arrhythmias group (9 days vs. 4 days, p < 0.001 and $121,826 vs. $37,658, p < 0.001, respectively). There was a substantial increase in the utilization of extracorporeal membrane oxygenation (ECMO) in patients with ventricular arrhythmias (25.4% vs. 2.7%, OR = 12.40; 95% CI 10.55-14.57; p < 0.001). The use of ventricular assist devices (VADs) was higher in patients with ventricular arrhythmias (4.5% vs. 1.3%, OR = 3.76; 95% CI 2.82-5.01; p < 0.001). An improvement in discharge survival was observed over the years of study in both VA and non-VA groups; associated with this decline in mortality, there was a rising trend of ECMO utilization.Conclusion: Development of ventricular arrhythmia in children with myocarditis is a strong predictor for mortality and ECMO utilization. What is Known: • The clinical presentation of pediatric myocarditis varies from no symptoms of myocardial dysfunction to a rapidly progressing severe congestive heart failure. • Little is known about the predictors of mortality in children with suspected myocarditis. What is New: • Development of ventricular arrhythmia in children with myocarditis is a strong predictor for mortality and ECMO utilization. • Improvement in discharge survival was observed over the years of study; associated with this decline in mortality, there was a rising trend of ECMO utilization.

Abstract
OBJECTIVE The objective of this study was to identify patient and hospitalization characteristics associated with in-hospital mortality in infants with truncus arteriosus. METHODS We conducted a retrospective analysis of a large administrative database, the National Inpatient Sample data set of the Healthcare Cost and Utilization Project for the years 2002 to 2017. We also sought to evaluate the resource utilization in the subgroup of subjects with truncus arteriosus and 22q11.2 deletion syndrome. Neonates with truncus arteriosus were identified by ICD-9 and ICD-10 codes. Hospital and patient factors associated with inpatient mortality were analyzed. RESULTS Overall, 3009 neonates met inclusion criteria; a total of 326 patients died during the hospitalization (10.8%). Extracorporeal membrane oxygenation utilization was 7.1%. Univariate and multivariate logistic regression analyses were used to identify risk factors for in-hospital mortality. Significant risk factors for mortality were prematurity (adjusted odds ratio [aOR] = 2.43; 95% confidence interval [CI]: 1.40-4.22; P = .002), diagnosis of stroke (aOR = 26.2; 95% CI: 10.1-68.1; P < .001), necrotizing enterocolitis (aOR = 3.10; 95% CI: 1.24-7.74; P = .015) and presence of venous thrombosis (aOR = 13.5; 95% CI: 6.7-27.2; P < .001). Patients who received extracorporeal membrane oxygenation support or had cardiac catheterization procedure during the hospitalization had increased odds of mortality (aOR = 82.0; 95% CI: 44.5-151.4; P < .001, and aOR = 1.65; 95% CI: 0.98-2.77; P = .060, respectively). CONCLUSION 22q11.2 deletion syndrome was associated with an inverse risk of death despite having more noncardiac comorbidities; this patient subpopulation also had a higher length of stay and increased cost of hospitalization.

Abstract
Neonates with hypoplastic left heart syndrome (HLHS) were identified from the National Inpatient Sample dataset for the years 1998-2014. These patients were stratified into two chronological groups, past group (1998-2005) and recent group (2006-2014). A total of 20,649 neonates with HLHS were identified. Of them, 9179 (44.5%) were born in the past group and 11,470 (55.5%) in the recent group. Median birth weight was significantly less in the recent group (2967 g vs. 3110 g, p = 0.005). The patients in the recent group had more patients with low birth weight ( < 2.5 kg) and prematurity (8.7% vs 7.6% and 12.7% vs. 4.3%., respectively). In addition, recent group had more comorbidities including chromosomal anomalies, total anomalous pulmonary venous return, and kidney anomalies (5.6% vs. 3.6%, 2.3% vs. 1.7%, and 5.6% vs. 3.6%, respectively, p < 0.001); these were associated with a higher rate of extracorporeal membrane oxygenation utilization (9.2% vs. 4.5%, p < 0.001). Consequently, median length of stay was longer in the recent group (8 vs. 6 days, p < 0.001).Conclusion: Despite the higher frequency of comorbidities in recent group, the mortality rates decreased by 20% (from 25.3% to 20.6%, p < 0.001). Balloon atrial septostomy was performed less frequently in the recent group (23.3% vs. 16.1%, p < 0.001).What is known:• Hypoplastic left heart syndrome has the highest mortality among congenital cardiac defects during the first year of life.• Limited studies on patients' comorbidities and mortality rates trends over last two decades.What is new:• The study utilized a national database to compare in-hospital mortality and length of stay between the two time periods 1998-2005 and 2006-2014.• The recent group had more comorbidities (prematurity, chromosomal anomalies, total anomalous pulmonary venous return, and kidney anomalies), and there was higher rate of ECMO and longer length of stay, while mortality rates decreased by 20%.

Abstract
Heparin has been used for decades as an anticoagulant in patients on mechanical circulatory support, which includes extracorporeal membrane oxygenation (ECMO) and ventricular assist devices. Bivalirudin is a direct thrombin inhibitor that can be used as an alternative anticoagulant in neonates and infants demonstrating inaccurate heparin monitoring. We report a case of a 2-month-old male child who was placed on ECMO for severe acute respiratory distress syndrome. His ECMO course was complicated by severe hemolysis and hyperbilirubinemia, which precluded accurate monitoring of heparin activity. Bivalirudin was successfully used for anticoagulation in this patient.

Abstract
Human amniotic membrane as a homograft material was compared to temporalis fascia to close tympanic membrane perforations in 50 patients with chronic otitis media. Human amniotic membrane was used in 20 patients while temporalis fascia was used in the remaining 30. Anatomical closure of the perforation and reduction of the air-bone gap was measured. The graft uptake showed a 65% success rate for the amniotic membrane and 56.7% for the temporalis fascia at 3 months post-operatively. Significant closure of air-bone gap was observed in the human amniotic group. These results indicate comparable outcomes between human amniotic membrane and the temporalis fascia graft.

Abstract
The differences in facial anatomical structures of the major ethnic groups, may also be reflected in nasal resistance. Active anterior rhinomanometry (AAR) is the recommended technique for the objective assessment of nasal airway resistance (NAR). This study comprised of 85 adult Malay subjects. All the subjects had to undergo a primary assessment of relevant symptoms of nasal disease and nasal examination before undergoing AAR assessment. The mean value of total nasal airway resistance (NAR) was 0.19 Pa/cm(3)/s (ranged from 0.09 to 0.55 Pa/cm(3)/s) at 75 Pa pressure point and 0.24 Pa/cm(3)/s (ranged from 0.12 to 0.52 Pa/cm(3)/s) at 150 Pa pressure point. The mean unilateral NAR was 0.46 Pa/cm(3)/s at a reference pressure of 75 Pa and 0.51 Pa/cm(3)/s at a reference pressure of 150 Pa. In this study we presented normal values for NAR in healthy Malay adult subjects. AAR proves to be a valuable clinical method for recording and quantitating nasal resistance.

Abstract
Nasal obstruction is a subjective complaint in patients with nasal disease. The ability to quantitate the nasal ventilation dysfunction would be useful for making the appropriate choice of nasal disease management. This cross-sectional study comprised of 200 adult subjects. They underwent assessment of relevant symptoms, nasal examination and investigations before undergoing active anterior rhinomanometry (AAR) assessment. A group of 88 normal subjects and 112 patients with nasal disease were included. The mean total nasal air resistance (NAR) was significantly higher in patients with nasal disease (0.33 Pa/cm(3)/s) as compared to normal subjects (0.24 Pa/cm(3)/s). There was no significant difference in total NAR between patients with symptoms of nasal obstruction and those without the symptoms (p = 0.42). It is concluded that AAR is a sensitive but not a specific tool for the detection of abnormalities in NAR and it failed to relate to the symptom of nasal obstruction.

Abstract
Four patients underwent reconstruction of anterior cranial fossa of skull defects between November 1997 and January 1998. All of them had traumatic anterior cranial fossa defect and were reconstructed with lyophilised bovine cortical bone graft. There was no cerebrospinal fluid leakage, meningitis, extradural abscess or other infections. This study demonstrates that the use of bovine bone graft in the reconstruction of anterior base defects is safe.

Abstract
Retropharyngeal abscess (RPA) is relatively rare today. A study of 17 cases of RPA treated at our hospital in the past 10 years showed a shift in the disease from children below 6 years of age (41%) to older children and adults (58%). Upper respiratory tract infection (URTI) was found to be the commonest (52%) aetiological predisposing factor in all age groups. Other aetiological factors were septicaemia (11%) in children below the age of 6 years and trauma due to foreign body (35%) in the older children and adult age groups. Klebsiella, Staphylococcus and Streptococcus were the commonest species of microorganisms grown from pus. The changing clinical trends, microbiology, choice of antibiotics, usefulness of radiology, and complications of this potentially fatal illness are discussed.

Abstract
Fourth branchial pouch anomalies are extremely rare and only a few such cases showing sinuses and cystic masses have been reported in the literature. We describe a patient who presented on the third day of life with cystic neck swelling of fourth branchial pouch origin giving rise to respiratory obstruction and stridor. Despite repeated aspiration of the cystic mass to relieve respiratory obstruction, rapid recurrence of the mass continued to cause stridor and ultimately required surgical excision. The clinical, radiological, and histopathological findings of this unusual condition are discussed with a review of the literature.

Abstract
A 14-year-old girl with a carcinoid tumor of the proximal right bronchus intermedius underwent a video-assisted thoracoscopic pneumonectomy. She was fully ambulant within 48 hours of surgery, had less pain than that normally associated with standard thoracotomy, and was discharged on the 7th postoperative day.

Abstract
Stool specimens from 334 infants and young children hospitalized with diarrhea in the General Hospital, Kuala Lumpur, Malaysia between August and November, 1987 were analyzed for the presence of rotavirus double-stranded (ds) RNA by polyacrylamide gel electrophoresis. Of the 334 specimens analyzed, 32 (9.6%) were positive for rotavirus RNA. One specimen (designated G147) exhibited a ds RNA electropherotype profile characteristic of Group C rotavirus and was selected for further characterization. In Northern blot hybridization studies, the gene 5 segment of strain G147 hybridized with a cDNA probe generated from the cloned gene 5 (which encodes the VP6 inner capsid protein that is group specific) of porcine Group C rotavirus strain Cowden, confirming the classification of strain G147 in Group C. The association of Group C rotavirus with diarrheal illness in Malaysia is consistent with earlier studies that suggest a global distribution of this virus and supports the need for additional epidemiologic studies.

Abstract
Internal jugular vein ectasia is a venous anomaly commonly presenting as a unilateral neck swelling in children and adults. Literature reports of bilateral presentation are rare. Bilateral Doppler ultrasonography is the diagnostic investigation of choice. The possible pathology, aetiology and management are discussed. Conservative management of bilateral cases is recommended in uncomplicated cases.

Personal and domestic hygiene and its relationship to the incidence of diarrhoea in south Sumatera. JOURNAL OF DIARRHOEAL DISEASES RESEARCH 1994; 12:42-8.

Abstract
The association of risk factors and diarrhoeal disease incidence among children less than 3 years of age in District Rambutan, South Sumatera, was investigated by a 20-week case-control study of 48 households with a high incidence of diarrhoeal diseases and 111 households with low incidence. Among sociodemographic characteristics, television ownership had a significant negative association with diarrhoeal disease incidence (odds ratio [OR] 3.22). The hygiene behaviour significantly associated with diarrhoeal diseases were: disposing of children's faeces in open places rather than in a latrine (OR > 10.47); bathing children in rivers rather than at wells (OR 2.88); children eating with their hands rather than with spoons (OR 5.6); household members defecating in open places rather than a latrine (OR 2.56); house without sewage system (OR 6.98). To control diarrhoeal disease in the study area, we suggest targeting three groups of behaviour for modification: those related to a) faeces disposal, b) sanitary drainage, and c) handwashing with soap and using spoons for eating.

Abstract
Intracavernous carotid artery aneurysm following head injury is a rare occurrence. Two such cases presenting with delayed but massive and repeated epistaxis are reported and the literature reviewed. The first case required a trapping procedure while the second case had only cervical carotid ligation to control the bleeding. Both resulted in no neurological sequelae.

Abstract
Four investigators conducted participative observation at 4 hamlets, representing 4 typical topography in the area, wet or dry near the river and wet or dry far from the river, in District Rambutan, South Sumatera Province, Indonesia from July 1988 up until February 1989 to study the community perception and practices on diarrheal diseases (DD). The observation was supported by focus group discussions and informal interviews. It was found that the causes of DD can be grouped into: dirty water; wrong (cold, hot, sting) food; part of the growth process; physical condition (extreme heat, cold wind and inner abnormality, inner heat, muscle strain), and supernatural. The type of DD can be grouped into: mild without vomiting named ngadi, negenteng-ngentengi, nambah kepacakan, etc which was linked to the growth process; more severe diarrhea, might be with fever (mising-mising, murus, mencret, etc); more severe diarrhea with severe vomiting (muntager, kolera); bloody/mucoid stool (disentri, mising tai angin, mising umbal). The community had also the concept of prolonged diarrhea named as menerus (literally meaning prolonged) Muntaber was more associated with bad water while the prolonged one was more associated with inner abnormality. The danger of diarrhea perceived was susut = shrinkage, lisut = emaciation. Pale and red hair with lisut were recognized as the dangers of prolonged diarrhea. The community did not associate these conditions with fluid loss. The management started by self medication using tapel (pasta of herb applied) to the stomach), decoct (daun jambu, akar teratai etc), solid oral preparation (cassava with raw sugar, rast rice, etc).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
An analysis of rotavirus electropherotypes circulating in Kuala Lumpur, Malaysia, over 7 years showed that all except 1 of the 360 electropherotypes encountered were characteristic of group A rotaviruses. The long electropherotype predominated annually, and there was a rarity of short electropherotypes. Extensive genome variability and cocirculation of different electropherotypes were observed annually. A sequential appearance of the predominant electropherotype was observed in all years of the study, except for 1985 and 1988, when one electropherotype predominated throughout the study periods. There was no shift in the predominant electropherotype over a 6-year period.
