Summary
Patients with spina bifida have a high risk of latex allergy, with sensitization found in 49%. Key risk factors include multiple surgeries and atopy, necessitating pre-operative screening for prevention.
Area of Science:
- Immunology
- Allergology
- Pediatric Surgery
Background:
- Spina bifida patients face significant risks from latex allergy due to repeated medical interventions.
- Latex sensitization is a growing concern in healthcare settings, particularly for vulnerable populations.
Purpose of the Study:
- To investigate the prevalence of latex allergy risk factors in patients with spina bifida.
- To identify specific indicators for latex sensitization and clinical allergy in this cohort.
Main Methods:
- A cohort of 165 spina bifida patients underwent questionnaires, skin-prick testing, and serum-specific IgE determination for latex.
- Screening for environmental allergen sensitization was also performed.
Main Results:
- 49% of patients (80/165) were sensitized to latex, confirmed by specific IgE.
- Clinically relevant latex allergy was observed in 19 patients, with 5 experiencing systemic reactions.
- Increased number of operations and atopic predisposition correlated with latex sensitization and allergy.
Conclusions:
- Pre-operative screening for latex allergy is crucial for spina bifida patients to prevent severe reactions.
- Risk factors include more than five operations, atopy, balloon inflation symptoms, and high specific IgE levels (CAP-class ≥ 4).

01:30Neurulation
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the anterior...
01:29Local Anesthetics: Clinical Application as Epidural Anesthesia
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

01:29Asthma-I: Introduction
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...
01:29Herniated Intervertebral Disc l: Introduction
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
