Development of clinical sign-based scoring system for assessment of omphalitis in neonatal calves

Omphalitis contributes significantly to morbidity and mortality in neonatal calves. Diagnosis of omphalitis is based on the local signs of inflammation—pain, swelling, local heat and purulent discharge. An abattoir trial identified an optimal, sign-based, scoring system for diagnosis of omphalitis. A sample of 187 calves aged between 7 and 15 days old were clinically examined for signs of umbilical inflammation and compared with postmortem examination of navels. On postmortem findings, 64 calves (34.2 per cent) had omphalitis. In the examined omphalitis cases, the most commonly affected umbilical structure was the urachus (78.1 per cent). Multivariable logistic regression revealed that thickening of the umbilical stump over 1.3?cm (P<0.001), discharge (P<0.001), raised local temperature (P=0.003) and the presence of umbilical hernia (P=0.024) were correlated and positive predictors of omphalitis. Discharge from the umbilical stump was associated with intra-abdominal inflammation (P=0.004). Assigning weights based on the multivariable logistic regression coefficients, a clinical scoring algorithm was developed. The cumulative score ranged from 0 to 9. Using this scoring system, calves were categorised as positive if their total score was =2. This scoring method had a sensitivity of 85.9 per cent, specificity of 74.8 per cent and correctly classified 78.6 per cent of all calves

Incidence and etiology of omphalitis in Pakistan: a community-based cohort study

Introduction: Although omphalitis (umbilical infections) among newborns is common and a major cause of neonatal deaths in developing countries, information on its burden and etiology from community settings is lacking. This study aimed to determine the incidence and etiology of omphalitis in newborns in high neonatal mortality settings in Karachi, Pakistan. Methodology: Trained community health workers surveyed all new births in three low-income areas from September 2004 to August 2007. Pus samples from the umbilical stumps were obtained from babies with pre-defined signs of illness and subjected to culture and antimicrobial susceptibility testing. Results: Among 6904 births, 1501 (21.7%) newborns were diagnosed with omphalitis. Of these, 325 (21.6%) were classified as mild, 1042 (69.4%) as moderate, and 134 (8.9%) as severe, 141 (9.3%) were associated with clinical signs of sepsis. The incidence of omphalitis was 217.4/1000 live births, moderate-severe omphalitis 170.3 per 1000 live births, and associated with sepsis 20.4 per 1000 live births. Of 853 infants with purulent umbilical discharge, 64% yielded 583 isolates. The most common pathogens were Staphylococcus aureus, of which 291 (95.7%) were methicillin-susceptible Staphylococcus aureus (MSSA) and 13 (4.2%) methicillin-resistant S. aureus (MRSA), Streptococcus pyogenes 105 (18%), Group B beta-hemolytic streptococci 59 (10 %), Pseudomonas spp., 52 (8.9 %), Aeromonas spp. 19 (3.2%), and Klebsiella spp. 12 (2%). Conclusions: A high burden of omphalitis can be associated with sepsis among newborns in low-income communities in Pakistan. S. aureus is the most common pathogen isolated from umbilical pus. Appropriate low-cost prevention strategies need to be implemented

Umbilical Cord Stump Infections in Central Uganda: Incidence, Bacteriological Profile, and Risk Factors

Umbilical cord stump infection (omphalitis) is a risk factor for neonatal sepsis and death. We assessed the incidence of omphalitis, described the bacteriological and antibiotic-resistance profile of potentially pathogenic bacteria isolated from the umbilical cord stump of omphalitis cases, and evaluated whether bacteria present in the birth canal during birth predicted omphalitis. We enrolled 769 neonates at birth at three primary healthcare facilities and followed them for 28 days with scheduled visits on days 3, 7, 14, and 28. Cox regression models were used to estimate the rates of omphalitis associated with potential risk factors. Sixty-five (8.5%) neonates developed omphalitis, with an estimated incidence of 0.095 cases per 28 child-days (95% CI 0.073, 0.12). Potentially pathogenic bacteria were isolated from the cord stump area of 41 (63.1%) of the 65 neonates with omphalitis, and the most commonly isolated species were Escherichia coli (n = 18), Klebsiella pneumoniae (n = 10), Citrobacter freundii (n = 5), and Enterobacter spp. (n = 4). The Enterobacteriaceace isolates were resistant to gentamicin (10.5%, 4/38), ampicillin (86.8%, 33/38), and ceftriaxone (13.2%, 5/38). Delayed initiation of breastfeeding was associated with an increased risk of omphalitis (aHR 3.1; 95% CI 1.3, 7.3); however, vaginal colonization with potentially pathogenic bacteria did not predict omphalitis.publishedVersio

Community-based management and outcome of omphalitis in newborns in Karachi, Pakistan

Objectives: To describe the clinical profile and outcome in newborns with omphalitis managed with home or clinic-based therapy.Methods: The descriptive study was conducted from September 2004 to August 2007 in three low-income communities in Karachi, Pakistan. Newborns with omphalitis detected by community health workers through active surveillance were referred to local clinics. Those with physician-confirmed omphalitis were treated for 7 days with topical gentian violet or oral cephalexin (as monotherapy) or topical gentian violet and oral cephalexin (combination therapy) at physician discretion, or injectable therapy (procaine penicillin and gentamicin) if clinical signs of sepsis were also present and family refused hospital referral. Follow-up was at 48-72 hours and 7 days. SPSS 16 was used for statistical analysis.Results: Among 1083 newborns with omphalitis, 578 (53.4%) had peri-umbilical cellulitis without purulent discharge; 365 (33.7%) had purulent discharge (with or without cellulitis); and 140 (13%) had omphalitis with sepsis Review of outcome data at one week showed that among 943 newborns without signs of sepsis, 938 (99.5%) had improved; 2 (0.2%) died, and 2 (0.2%) were lost to follow-up. There were 5 (3.6%) therapy failures, among 140 newborns with omphalitis and sepsis managed with parenteral antibiotics at 48 hours, but 139 (99.2%) had improved by one week, while 1 (0.8%) died.Conclusion: In resource-constrained environments, omphalitis can be managed in the community with minimal need for hospital referral. Further research to define optimal therapeutic regimens is needed

Dialkylcarbamoyl chloride (DACC)-coated dressings in the management and prevention of wound infection: A systematic review

Objective: Dialkylcarbomoyl chloride (DACC)-coated dressings (Leukomed Sorbact and Cutimed Sorbact) irreversibly bind bacteria at the wound surface that are then removed when the dressing is changed. They are a recent addition to the wound care professional's armamentarium and have been used in a variety of acute and chronic wounds. This systematic review aims to assess the evidence supporting the use of DACC-coated dressings in the clinical environment. Method: We included all reports of the clinical use of DACC-coated dressings in relation to wound infection. Medline, Embase, CENTRAL and CINAHL databases were searched to September 2016 for studies evaluating the role of DACC-coated dressings in preventing or managing wound infections. Results: We identified 17 studies with a total of 3408 patients which were included in this review. The DACC-coating was suggested to reduce postoperative surgical site infection rates and result in chronic wounds that subjectively looked cleaner and had less bacterial load on microbiological assessments. Conclusion: Existing evidence for DACC-coated dressings in managing chronic wounds or as a surgical site infection (SSI) prophylaxis is limited but encouraging with evidence in support of DACC-coated dressings preventing and treating infection without adverse effects

Clean birth kits to improve birth practices: development and testing of a country level decision support tool

Background: Clean birth practices can prevent sepsis, one of the leading causes of both maternal and newborn mortality. Evidence suggests that clean birth kits (CBKs), as part of package that includes education, are associated with a reduction in newborn mortality, omphalitis, and puerperal sepsis. However, questions remain about how best to approach the introduction of CBKs in country. We set out to develop a practical decision support tool for programme managers of public health systems who are considering the potential role of CBKs in their strategy for care at birth. Methods: Development and testing of the decision support tool was a three-stage process involving an international expert group and country level testing. Stage 1, the development of the tool was undertaken by the Birth Kit Working Group and involved a review of the evidence, a consensus meeting, drafting of the proposed tool and expert review. In Stage 2 the tool was tested with users through interviews (9) and a focus group, with federal and provincial level decision makers in Pakistan. In Stage 3 the findings from the country level testing were reviewed by the expert group. Results: The decision support tool comprised three separate algorithms to guide the policy maker or programme manager through the specific steps required in making the country level decision about whether to use CBKs. The algorithms were supported by a series of questions (that could be administered by interview, focus group or questionnaire) to help the decision maker identify the information needed. The country level testing revealed that the decision support tool was easy to follow and helpful in making decisions about the potential role of CBKs. Minor modifications were made and the final algorithms are presented. Conclusion: Testing of the tool with users in Pakistan suggests that the tool facilitates discussion and aids decision making. However, testing in other countries is needed to determine whether these results can be replicated and to identify how the tool can be adapted to meet country specific needs

Magnesium sulphate in the treatment of acute asthma: evaluation of current practice in adult emergency departments

Background: A recent meta-analysis showed that intravenous and nebulised magnesium sulphate have similar levels of evidence to support their use in the treatment of acute asthma in adults. This consisted of weak evidence of effect on respiratory function and hospital admissions, with wide confidence intervals ranging from no effect to significant positive effects. Current BTS/SIGN guidelines suggest an equivocal role for intravenous magnesium sulphate and no role for nebulised magnesium sulphate. A study was performed to assess what emergency physicians currently do in their management of acute asthma. Method: A postal survey was undertaken of all adult emergency departments within the UK. A structured question naire was sent to all clinical leads in emergency medicine about their current usage of both intravenous and nebulised magnesium sulphate in the treatment of acute asthma. Results: 180 of the 251 emergency departments in the UK responded (72%). Magnesium sulphate was used in 93%, mostly because it was expected to relieve breathlessness (70%) or reduce HDU/ITU admissions (51%). It was predominantly given to those patients with acute severe asthma (84%) and life-threatening exacerbations (87%), with most stating they would give the drug if there was no response to repeated nebulisers (68%). In comparison, nebulised magnesium sulphate was only used in two emergency departments (1%). The main reason for not administering the drug via a nebuliser was insufficient evidence (51%). Conclusions: Intravenous magnesium sulphate is widely used for acute asthma, usually for patients with severe or life-threatening asthma who have not responded to initial treatment. Nebulised magnesium sulphate, by contrast, is hardly used at all. The use of intravenous magnesium sulphate is more extensive than current guidelines or available evidence would appear to support

Falciform Ligament Abscess after Omphalitis: Report of a Case

A falciform ligament abscess is a rare type of intra-abdominal abscess. A 2-yr-old male, who had omphalitis two months previously, presented with a fever and right upper quadrant abdominal pain. The ultrasound and CT scan showed an abdominal wall abscess located anterior to the liver, which was refractory to conservative management with percutaneous draninage and antibiotics. On the third recurrence, surgical exploration was performed and revealed an abscess arising from the falciform ligament; the falciform ligament was excised. A follow up ultrasound confirmed complete resolution of the abscess with no further recurrence

Effi cacy of chlorhexidine application to umbilical cord on neonatal mortality in Pemba, Tanzania: a community-based randomised controlled trial

Background In low-income countries, including the east African region, a third of neonatal deaths are due to infections. A substantial proportion of these have been attributed to sepsis, which can result from umbilical cord infections. Evidence from Asia suggests that chlorhexidine application to the neonatal umbilical cord reduces mortality, but no data from Africa are available. We aimed to assess the eff ect of umbilical cord cleansing with 4% chlorhexidine solution on neonatal mortality and omphalitis in rural settings of sub-Saharan Africa. Methods We did a community-based randomised controlled trial on Pemba Island, Zanzibar, Tanzania. All eligible babies (aged 1 h to 48 h, without congenital malformations) from hospital-based and community-based deliveries on Pemba Island were enrolled. Participants were randomly assigned to either 4% free chlorhexidine for cord care or to dry cord care using a computer-generated random sequence. For babies allocated to the chlorhexidine group, mothers or caretakers were advised to apply the solution to the cord every day until 3 days after the cord had dropped off . Cord stumps were examined for redness, pus, swelling, and foul odour on day 0, 1, 4, 10, and 28. The primary outcome for this study was mortality until day 28 on an intention-to-treat basis. The trial is registered with ClinicalTrials.gov, number NCT01528852. Findings Between May 19, 2011, and Aug 31, 2014, 36 911 newborn babies were enrolled into the chlorhexidine (n=18 015) and dry cord care study (n=18 896) groups. 17 468 (96·9%) of 18 015 neonates in the chlorhexidine group were available for complete follow-up (28 days) compared with 18 384 (97·3%) of 18 896 neonates in the dry cord care group. Mortality rate in the chlorhexidine group (10·5 deaths per 1000 livebirths) was not signifi cantly lower than that in the dry cord care group (11·7 per 1000 livebirths; relative risk 0·90, 0·74–1·09; p=0·27). Interpretation Our fi ndings do not support the use of chlorhexidine for reduction of neonatal mortality in this east African setting, which might not justify a change in the WHO policy. To inform global policy, a detailed meta-analysis and pooled analysis needs to be undertaken using data from both African and Asian settings
