Constipation and poor feeding in an infant with botulism

From Rarity to Recognition: Infantile Botulism and the Broad Spectrum of Differential Diagnoses

This case illustrates a 5-week-old girl who presented with decreased activity, decreased feeds, poor suck, weak cry, lethargy, hypotonia, and areflexia. The child was found to have infant botulism. The case demonstrates the importance of a full history and broad differential in an ill-appearing infant. The differential for an ill-appearing infant should always include infectious etiologies and may include metabolic disorders, congenital anomalies, nonaccidental trauma, neurologic disorders, and endocrine disorders. The broad differential diagnosis may make rapid diagnosis and treatment for infantile botulism a challenge.

Knowledge, attitude and practice among mothers on the relationship between honey and botulism in Saudi Arabian infants: a cross-section study

BACKGROUND

Botulism is a rare disease, and infant botulism (IB) even rarer, especially when steering the condition to honey consumption. IB is considered a life-threatening disease as it leads to severe neurological symptoms. Exploring the knowledge, attitude, and practice (KAP) among mothers on the relationship between honey and IB will help public health professionals implement appropriate maternal health education materials targeting infant health and increase the awareness of the paediatric primary care providers, physicians, and nurse practitioners about the risk of IB among their patients.

OBJECTIVES

To determine the knowledge of mothers from Hail city in Saudi Arabia (SA) regarding IB and assess their attitude and practice towards feeding honey to their infants before 12 months of age.

METHODS

Using a comparative cross-sectional study, in February 2022, we broadcasted an online questionnaire through social networking and evaluated the KAP of 385 mothers.

RESULTS

Less than half (48%) of the mothers have heard about IB, 40% of them knew the relation between honey ingestion and IB and only 6.5% acknowledged that they knew the causative agent for IB. The prevalence of feeding honey to infants before 12 months was 52%. Mothers from Hail city were less likely to provide honey to their infants (p = 0.002).

CONCLUSION

The study revealed that mothers from Hail city have relatively low knowledge of IB and that they hold favourable perceptions of using honey as a food supplement and feeding honey to their infants before 12 months. Considering the high prevalence of honey feeding with the known low incidence of IB in SA, Medical professionals should consider IB in their differential diagnosis particularly in the presence of neurological symptoms.

Epidemiology and risk factors for notifiable Clostridium botulinum infections in Taiwan from 2003 to 2020

Botulinum toxin is produced by Clostridium botulinum, a gram-positive anaerobic bacterium. This study aimed to examine the epidemiological characteristics, including sex, age, season in which infection occurred, place of residence, and epidemiological trends, of confirmed botulism cases in Taiwan from 2003 to 2020. This study examined the annual summary data on reported botulism in Taiwan' s Center for Disease Control from 2003 to 2020 available to the public on the internet. We found that there were 50 confirmed domestic cases of botulism. The incidence of botulism ranged from 0 to 0.48 per 1000,000 from 2003 to 2020 and peaked in 2008 and 2010. During the 18-year investigation period in which 6-year intervals were used, the study results showed a decreasing trend (2003-2008, 2009-14, and 2015-2020, had 22, 19, 9 cases each). In terms of patients' gender, age, and place of residence, most of the patients were females (56%), were aged ≥ 50 years (48%), and resided in Taipei and northern Taiwan (44%). The number of botulism cases in Taiwan from 2012 to 2020 compared with other years (from 2003 to 2011) found that there were significant differences among patients within an age group of <20 years (P = .003, odds ratio = 18.500, and 95% confidence interval = 3.287-104.111), and there were significant differences among patients whose place of residence was Taipei metropolitan area (P = .025, odds ratio = 5.667, and 95% confidence interval = 1.248-25.734). During 2003 to 2009, there was no case of botulism among those aged <20 years. Over the last 10 years, botulism in children showed an increasing trend. A total of 9 children were found to have botulism during 2010 to 2020; most of these children were male (66.7%) and were infected during spring and summer (66.7%). This study is the first to report the number of confirmed domestic cases with botulism from surveillance data from Taiwan's Center for Disease Control during 2003 to 2020. This study also found that the place of residence and age were associated with an increased risk of botulism in Taiwan. This information may be useful for policymakers and clinical experts to direct prevention- and control-based activities regarding botulism that result in the most severe illness and the greatest burden on Taiwanese.

A summary of surveillance, morbidity and microbiology of laboratory-confirmed cases of infant botulism in Canada, 1979-2019

Background

Infant botulism is a rare toxicoinfectious disease caused by colonization of the infant's intestine with botulinum neurotoxin-producing clostridia (i.e. Clostridium botulinum or neurotoxigenic strains of C. butyricum or C. baratii). Our goal was to examine data from laboratory-confirmed cases of infant botulism reported in Canada to summarize incidence over time, over geographic distribution by province or territory, and by sex, and to compare these parameters with data from the Canadian Notifiable Disease Surveillance System (CNDSS). The average age of onset, serotype of botulinum neurotoxin (BoNT), case outcomes, length of hospitalization and suitability of clinical specimens for laboratory confirmation were also determined.

Methods

We examined laboratory records from the Health Canada Botulism Reference Service and the British Columbia Centre for Disease Control (BCCDC) Public Health Laboratory. The Discharge Abstract Database (DAD) and the Hospital Morbidity Database (HMDB) of the Canadian Institute of Health Information (CIHI) were queried for data on hospitalization of infant botulism cases. The CNDSS was queried for data on reported cases of infant botulism.

Results

From 1979 to 2019, 63 laboratory-confirmed cases of infant botulism were confirmed by the Health Canada Botulism Reference Service and the BCCDC Public Health Laboratory for an annual rate of 4.30 cases per million live births. From 1983 to 2018, 57 cases of infant botulism were reported to the CNDSS. Of the 63 cases confirmed by the reference laboratories, the median age of onset was 16 weeks with a range of 2 to 52 weeks. The majority of cases were type A (76%) and B (21%), with single cases of type F and type AB. Of the 23 laboratory-confirmed cases with matched hospital records, 13 were transferred to special care and eight needed ventilator support; no deaths were reported.

Conclusion

Spores of C. botulinum are present naturally in the environment, thus diagnosis of infant botulism does not require a history of exposure to high-risk foods such as honey. Stool samples are the most useful diagnostic specimen.
