Profile of latex sensitization and allergies in children and adolescents with myelomeningocele in São Paulo, Brazil.

BACKGROUND: Latex allergy is an important cause of occupational allergy. In many countries the prevalence of latex allergy is still high and the profile of latex sensitization is unknown. OBJECTIVES: To evaluate the frequency of sensitization and allergy to latex in children and adolescents with myelomeningocele and to identify associated risk factors. METHODS: The study included 55 children and adolescents with myelomeningocele followed at a specialized center. In addition to a standard questionnaire and skin prick tests (SPTs) to aeroallergens and total latex, the patients underwent determination of total and specific serum IgE to latex and recombinant allergens. RESULTS: We observed a prevalence of 25% for latex sensitization and of 20% for latex allergy. Twenty-four patients (43.6%) were atopic and the average age for the first reaction to latex was 44.5 months. Cutaneous reactions were the most frequently reported reactions (72.7%). Specific immunoglobulin (Ig) E to rHev b 1, rHev b 3, rHev b 5, rHev b 6.1, and rHev b 6.2 was detected in over 50% of patients allergic to latex. Multivariate analysis showed current asthma, atopy, and having undergone 4 or more operations to be risk factors for latex sensitization. CONCLUSIONS: Our study documented a high prevalence of sensitization and allergy to latex in patients with myelomeningocele. Specific IgE to rHev b 1, rHev b 3, rHev b 5, rHev b 6.1, and rHev b 6.2 was detected in over 50% of children and adolescents with myelomeningocele who are allergic to latex. A history of current asthma, atopy, and having undergone 4 or more operations were independent risk factors for latex allergy.

Management of internal and external root resorption in primary teeth of a 3-year-old with myelomeningocele: A case report.

BACKGROUND: Myelomeningocele (MMC) is a severe manifestation of spina bifida. Children with MMC have motor disability, hydrocephalus, skeletal abnormalities, and mental retardation. These individuals are more susceptible to caries due to poor oral hygiene, carbohydrate-rich diet, prolonged use of sugar-containing medications and limited motor abilities. Latex allergy is an important factor to be considered during the dental rehabilitation of such patients. CASE REPORT: A 3-year-old girl visited the dental clinic with the chief complaint of multiple carious teeth and H/o neural tube defect (NTD) which had been operated on at the age of 6 weeks. On dental examination, multiple dental abscesses and severe early childhood caries were noted. Radiographic evaluation revealed internal root resorption of tooth "K" and external root resorption of tooth "T." The two teeth were treated with ledermix paste followed by obturation with Vitapex® (Diadent Group International Inc., Burnaby, BC, Canada) along with triple antibiotic paste and placement of stainless steel crown (SSC). A latex-free environment was maintained during the entire treatment to prevent allergic reaction. A follow up after 42 months indicated clinical and radiographical success. CONCLUSION: The paper reports succesfull management of internal and external root resorption as well as latex allergy in a dental operatory. The dental perspective while dealing with patients having NTD is limited. Explaining the particulars of the treatment plan will aid in management of such cases .

Tibial Cortex Transverse Distraction Followed by Open Correction with Internal Fixation for Management of Foot and Ankle Deformity with Ulcers.

OBJECTIVE: To assess the feasibility and results of tibial cortex transverse distraction (TCTD) followed by open correction with internal fixation (OCIF) for foot and ankle deformity with concurrent ulcers. METHODS: A retrospective analysis was conducted. Between 2010 and 2019, a two-stage management of TCTD followed by OCIF was performed in 13 patients (13 feet). There were five males and eight females with a mean age of 33.8 ± 14.6 years. Ten patients had a right-side lesion, and three patients had a left-side lesion. The etiology of deformity included seven cases of congenital neurological disease, one case of Charcot-Marie-Tooth disease, one case of trauma sequelae, and three cases of myelomeningocele. Duration of disease, size of ulcers, surgical procedures, healing time, external fixation time, and complications of these patients were recorded. The Texas wound classification and National Pressure Ulcer Advisory Panel (NPUAP) classification were used for assessing the ulcers. The modified Dimeglio score of deformity and American Orthopeadic Foot and Ankle Society (AOFAS) ankle-hindfoot score were applied to evaluate the status before treatment and the results at final follow-up. RESULTS: The TCTD and wound debridement were performed in all patients, and an additional Ilizarov correction technique was added in two patients. All ulcers were healed in 3 months after first-stage treatment. The median patient self-report time of ulcer healing was 2.0 weeks (IQR, 1.8-3.3). The median external fixation time was 138.0 days (IQR, 134.5-141.5) days. After second-stage operative correction, the patients were followed-up for an average of 28.0 ± 2.9 months. At the final follow-up, the modified Dimeglio score of deformity was decreased from 6.7 ± 2.1 to 1 (IQR, 0.0-1.0), and the mean AOFAS score was improved from 42.9 ± 19.1 to 82.6 ± 7.7. Before the treatment, there were eight patients with severe deformity, four patients with moderate deformity, and one patient with mild deformity. Postoperatively, seven patients were classified as mild deformity and six patients had a postural foot. The results of AOFAS ankle-hindfoot score were defined as excellent in three patients, as good in five, and as fair in five. Complications include one case of mild displacement of the osteotomized cortex and one case of pin-tract infection. No delayed union, nonunion, relapse of ulcers, or deformity were observed. CONCLUSIONS: The two-stage management of TCTD followed by OCIF could be considered as an alternative treatment for foot and ankle deformities combined with chronic ulcers.

Strategies and dental care in the treatment of patients with myelomeningocele.

Myelomeningocele (MMC) is a congenital malformation that occurs in the embryonic period, characterized by failure in closure of the caudal portion of the neural tube during central nervous system formation. Alterations and complications can be associated with this condition, such as hydrocephalus, neurogenic bladder, orthopedic problems, and motor and cognitive impairment. This patients with MMC also have predisposition to develop latex allergy and high caries risk and activity due to deficient oral hygiene, fermentable carbon hydrate-rich diet and prolonged use of sugar-containing oral medications. This paper reports the oral findings and dental treatment in a 15-year-old female patient diagnosed with MMC and describes the strategies used to improve dental treatment conditions and reduce the impact of associated risks to her health. The measures and precautions adopted in this case could be useful to reduce the barriers for patients with the same condition to access oral health care: regular visits to the dentist, initiating as early as possible; frequent reinforcement of oral homecare instructions and diet counseling; minor adaptions to the dental chair and dental office to improve ease of access due to patients' mobility problems; prevention of latex-related allergic reactions; reduction of gag reflex during dental procedures.

De Novo Spinal Dural Arteriovenous Fistula in a Patient with a Lipomyelomeningocele: Case Report.

BACKGROUND: Spinal dural arteriovenous fistula (AVF), the most common type of spinal vascular malformation, tends to manifest as progressive myelopathy over several years. Spinal dural AVFs are considered an acquired lesion and, in contrast to spinal arteriovenous malformations, are not often associated with other anomalies. The presence of a spinal dural AVF in the setting of a lipomyelomeningocele and tethered cord is extremely rare. Both lesions tend to cause similar symptoms, and patients with concomitant lesions generally require surgical intervention for both. CASE DESCRIPTION: A 57-year-old female with lifelong urinary incontinence and mild weakness in the left lower extremity presented with progressive worsening of left lower extremity weakness as well as worsening bowel and bladder incontinence. Magnetic resonance imaging (MRI) performed 4 years before our evaluation revealed a lipomyelomeningocele and a tethered cord; a new MRI demonstrated a new additional finding of flow voids suspicious of an underlying vascular malformation. Diagnostic angiography revealed a dural AVF fed by a left lateral sacral artery. Onyx embolization of the dural AVF was performed, and the patient improved steadily postoperatively without the need for surgically addressing the tethered cord. CONCLUSION: In this case report, we present evidence of de novo development of a spinal dural AVF associated with a lipomyelomeningocele. In addition, this is the second documented patient in the literature with a lipomyelomeningocele and concomitant dural AVF who did not undergo detethering of the cord as part of treatment.

Fasting serum blood measures of bone and lipid metabolism in children with myelomeningocele for early detection of cardiovascular and bone fragility risk factors.

OBJECTIVE: This study examined serum levels in children with myelomeningocele to identify the prevalence of pre-clinical signs of disease. DESIGN: A prospective, cross-sectional study. SETTING: Patients were actively recruited from multidisciplinary care clinics at tertiary children's hospitals from 2010-2012. The control comparison group was recruited by word-of-mouth. PATIENTS: Twenty-eight children with myelomeningocele (93% Hispanic; 17 males; 10.0 ± 2.1 years) and 58 controls (84% Hispanic; 30 males; 10.4 ± 2.4 years) provided ≥ 8-hour fasting blood samples with concomitant dual-energy x-ray absorptiometry measurements of body fat. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The serum analysis included a lipid panel (cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein), insulin, glucose, leptin, aspartate aminotransferase, alanine transaminase, alkaline phosphatase, albumin, creatinine, calcium, phosphatase, parathyroid hormone, and vitamin D. RESULTS: Children with myelomeningocele had higher body fat (35.2% versus 29.9%, p=0.01) and altered lipid profiles (lower high-density lipoprotein levels, 43.9 mg/dL versus 51.6 mg/dL, P = 0.03) suggesting elevated risk of metabolic syndrome. They also had a higher prevalence of vitamin D deficiency (43% versus 17%, p=0.02) and significantly lower levels of calcium (9.4 mg/dL versus 9.7 mg/dL, P = 0.003) and alkaline phosphatase (187.0 U/L versus 237.0 U/L, P = 0.003). Unexpectedly children with myelomeningocele had lower parathyroid hormone levels (14.5 pg/mL versus 18.4 pg/mL, P = 0.02) than controls despite lower calcium, vitamin D and alkaline phosphatase levels. This suggests an alteration in the sensing mechanism or response of the parathyroid gland to normal physiological stimuli in patients with myelomeningocele. CONCLUSIONS: Children with myelomeningocele have abnormal biochemical markers for cardiovascular disease, insulin resistance and bone and mineral metabolism. Early recognition and monitoring of these risk factors in patients with myelomeningocele may help prevent later complications.

Polyethylene glycol 4000 vs. lactulose for the treatment of neurogenic constipation in myelomeningocele children: a randomized-controlled clinical trial.

AIM: To compare the therapeutic effectiveness and tolerability of low daily doses of polyethylene glycol 4000 vs. lactulose in the treatment of neurogenic constipation in children with myelomeningocele. METHODS: Sixty-seven children with chronic neurogenic constipation were randomized allocated to receive either polyethylene glycol 4000 (0.50 g/kg) or lactulose (1.5 g/kg) for 6 months. Patients or their parents reported frequency and modality of evacuation and side effects on a diary card. Primary outcome was bowel frequency > or =3/week, and the second one was side effects at the end of treatment. RESULTS: Complete remission of constipation was reported by a significantly (P < 0.01) higher number of patients treated with polyethylene glycol compared with lactulose. At the end of the study, 46% patients of polyethylene glycol group and 22% of the lactulose group were asymptomatic. Compared with lactulose, patients treated with polyethylene glycol reported higher bowel frequency (5.1 vs. 2.9 bowel movements/week, P < 0.01) and reduction of encopresis. Neither lactulose nor polyethylene glycol caused clinically-significant serious side effects and palatability was similar. CONCLUSIONS: Polyethylene glycol 4000 compared with lactulose provided a higher success rate, without significant side effects, for the treatment of constipation in myelomeningocele children.

Prevalence of latex allergy in a population of patients diagnosed with myelomeningocele.

INTRODUCTION: Latex allergy is one of the main reasons of anaphylaxis in the operating room. The prevalence of this condition is higher among patients with myelomeningocele. Epidemiological data obtained from Argentine patients is scarce. OBJECTIVE: To estimate the prevalence of latex sensitivity and latex allergy in a population of patients with myelomeningocele and to describe associated risk factors. POPULATION AND METHODS: Descriptive, cross-sectional, observational study. Family and personal history of allergy, number of surgeries, history of symptoms caused by having been in contact with latex or cross-reactive foods, eosinophil count, measurement of total immunoglobulin E and specific immunoglobulin E levels by means of skin and serologic testing for latex, aeroallergens and cross-reactive fruit. RESULTS: Eighty-two patients diagnosed with myelomeningocele were assessed: 41 were males and their average age was 15.3 ± 7.66 years old. Out of all patients, two did not complete skin and serologic testing. Among the remaining 80 patients, 16 (19.51%) had latex allergy, 46 (57.5%) were not allergic, and 18 (22%) showed sensitivity but not allergy. Having undergone more than five surgeries was a risk factor associated with latex allergy (p= 0.035). No significant association was observed with the remaining outcome measures. CONCLUSION: According to this study, the prevalence of latex allergy in this population of patients is 19.51% and the most important risk factor for this condition is a history of having undergone more than five surgeries.

INTRODUCCIÓN: La alergia al látex se encuentra dentro de las primeras causas de anafilaxia en el quirófano. La prevalencia de esta enfermedad es más elevada en pacientes con mielomenigocele. Existen escasos datos epidemiológicos en pacientes argentinos. OBJETIVO: Estimar la prevalencia de la sensibilidad y de la alergia al látex en una población de pacientes con mielomeningocele y describir los factores de riesgo asociados. PACIENTES Y MÉTODOS: Estudio descriptivo, transversal, observacional. Se analizaron los antecedentes familiares y personales de alergia, el número de procedimientos quirúrgicos, la historia de síntomas ante el contacto con látex o alimentos con reactividad cruzada, el recuento de eosinófilos, la inmunoglobulina E total y la inmunoglobulina E específica mediante pruebas serológicas y cutáneas para el látex, los aeroalérgenos y las frutas con reactividad cruzada. RESULTADOS: Se evaluaron 82 pacientes con diagnóstico de mielomeningocele, 41 del sexo masculino (50%), con edad promedio de 15,3 ± 7,66 años. Del total de los pacientes, 2 no realizaron las pruebas cutáneas y serológicas. De los 80 restantes, 16 (19,51%) presentaban alergia al látex, 46 (57,5%) no eran alérgicos y 18 (22%) fueron sensibles pero no alérgicos. Se observó que haber tenido más de 5 cirugías representaba un factor de riesgo asociado a alergia al látex (p= 0,035). No se encontró una asociación significativa con el resto de las variables evaluadas. CONCLUSION: El estudio estima que la prevalencia de alergia al látex en esta población de pacientes es de 19,51% y que el factor de riesgo más importante para el desarrollo de esta patología es el antecedente de haber sido sometido a más de 5 intervenciones.

A novel use of dextranomer/hyaluronic acid copolymer.

The aim of this study is to present a novel use of Dextranomer/hyaluronic acid copolymer (Deflux) for the treatment of a complicated iatrogenic chronic urethral injury. A 12-year-old boy with a neuropathic bladder presented a groove in the urethral mucosa due to chronic clean intermittent catheterizations (CICs) and suffered a posterior urethral injury during a failed catheterization for a routine examination. The defect on the urethral wall was repaired using Deflux, a technique that is not described in the literature. After the intervention the patient is continuing CICs without further complications.

Myelomeningocele, Arnold-Chiari anomaly and hydrocephalus in focal dermal hypoplasia.

Focal dermal hypoplasia (FDH) is an X-linked dominantly inherited syndrome of cutaneous, skeletal, dental, ocular, and soft tissue defects. We report on a female infant with FDH with the first observation of myelomeningocele with hydrocephalus and Arnold-Chiari malformation.

Intraoperative anaphylactic reaction due to latex hypersensitivity.

Severe anaphylactic reaction secondary to latex allergy has lately been recognized and reported especially in individuals with spina bifida. We report a case of severe intraoperative anaphylactic reaction due to latex allergy. Preoperative testing for latex allergy may be helpful in determining latex allergy. We suggest a preoperative management protocol for patients who are thought to have latex allergy. An increased awareness to latex allergy will help avoid this potentially catastrophic event.

Bladder management in patients with pediatric onset neurogenic bladders.

Our objective was to determine which clean intermittent catheterization (CIC) methods and supplies were used by patients with pediatric onset neurogenic bladders and to relate methodology and materials to reported urinary tract infections. Data were collected via questionnaires distributed by mail and at clinic visits at our university tertiary care outpatient pediatric rehabilitation clinic. Questionnaires were given to 165 patients. Fifty-nine percent were returned (68 patients with myelomeningocele, 27 with pediatric onset spinal cord injury (SCI) and two with other diagnoses). Mean age was 12 years (range 1-27). Fifty-four percent of patients participated in their own CIC. Only two percent used sterile catheterization technique, whereas 98 percent used CIC. A sterile catheter was employed with clean technique by 22 percent. Catheters were reused by 76 percent. Subjects used a wide ranging number of catheters per month, with a median of 5.3. There was no correlation between the number of urinary tract infections (UTIs) per year and the type of catheter used or the use of prophylactic antibiotics. Compared with patients with myelomeningocele, subjects with SCI were significantly more likely to use sterile catheters (p = 0.04), > 10 catheters per month (p = 0.01) and gloves (p < 0.001). Subjects who used gloves or more catheters were more likely to experience UTI. These data suggest that clean reused supplies are not related to an increased likelihood of UTI and should be considered a way to lower costs in these populations.

Use of the silastic sheath in bladder neck reconstruction.

OBJECTIVE: The study compared two populations of patients undergoing bladder neck reconstruction using the silastic sheath in two major pediatric centers. The success with this technique was markedly different in the two centers. The purpose of the study was to determine factors that might explain the divergent results. PATIENTS AND METHODS: Fifteen patients treated in Indianapolis were compared with 94 patients treated in London with the silastic sheath technique of bladder neck reconstruction. Eighty-seven percent of the Indianapolis patients had myelomeningocele whereas 86% of the London group had exstrophy/epispadias. Median age of the Indianapolis patients was 11 years whereas it was 8.4 years in London. Seventy-three percent of patients in Indianapolis were female and 79% in London were male. Patients were followed for a minimum of eight years in Indianapolis and a mean of seven years in London. Similar surgical technique was employed in the two centers but, over time, the London approach included use of a non-reinforced silastic wrapped loosely around the bladder neck with the interposition of omentum. RESULTS: Both groups achieved continence rates exceeding 90%. Of the Indianapolis patients, two-thirds experienced erosion of the silastic at a mean of 48 months. With modifications in the London technique, the erosion rate of silastic was lowered from 100% to 7%. CONCLUSION: Direct, snug wrap of silastic without omentum around the Young-Dees tube as well as simultaneous bladder augmentation placed patients at increased risk for erosion. The silastic sheath technique may be less applicable to myelomeningocele patients. It seems most applicable to older male patients with exstrophy or epispadias undergoing Young-Dees bladder neck reconstruction who have the ability to void.

[Latex allergy in children with myelomeningocele. Incidence and associated factors]. / Alergia al látex en niños con mielomeningocele. Incidencia y factores asociados.

RATIONALE: The purpose of our work is to know the prevalence of allergies to latex in patients with myelomeningocele (MMC) and to evaluate any potential factors influencing its development. METHODS: The study included 100 children with mean age 7.5 +/- 4.8 years, diagnosed with MMC by skin tests and total and latex-specific IgE determination. The results were compared to those obtained in three "control" groups: atopic patients, patients undergoing their first operation and multi-operated patients. The relationship between the different variables analyzed was assessed using univariant and multivariant statistical studies. RESULTS: 29 were sensitized (15 symptomatic and 14 asymptomatic) and 8 doubtful. Results showed statistically significant (p < 0.05) differences for atopic and first operation groups and non significant differences for the multi-operation group. The multivariant study selected the followed as the most relevant variables: number of surgical interventions, total IgE levels in z units, ventricle-peritoneal by-pass carriers and atopy background. Also in the multivariant study, the following showed statistically significant results: age, Cums' number, inclusion in intermittent catheterism program and total IgE levels. Neither sex or familial background of atopy showed statistical significance. CONCLUSIONS: Allergy to latex in MMC patients is related to multiple antigen contacts, the numerous manipulations and operations undertaken throughout the patient's life plus a personal propensity to allergies. It is essential that this group should adopt certain standards to minimize contact with the antigen and undergo an allergological study so as to detect those who are sensitized, which in nearly half our series has not yet exhibited symptomatology in contact with latex utensils. All diagnostic and therapeutical procedures should be conducted in latex-free environments.

Oral findings and dental care in a patient with myelomeningocele: case report of a 3-year-old child.

Myelomeningocele (MMC) is a congenital malformation of the neural tube that occurs in the first weeks of pregnancy. This malformation refers to the caudal non-closure of the neural tube and neural tissue exposure, which lead to neurological problems, such as hydrocephalus, motor disability, genitourinary tract and skeletal abnormalities and mental retardation. Patients with MMC have an acknowledged predisposition to latex allergy and are usually at a high caries risk and activity due to poor oral hygiene, fermentable carbon hydrate-rich diet and prolonged use of sugar-containing medications. This paper addresses the common oral findings in pediatric patients with MMC, discusses the strategies and precautions to deal with these individuals and reports the dental care to a young child diagnosed with this condition.

Complications of clean intermittent catheterization in young females with myelomeningocele: 10 to 19 years of followup.

PURPOSE: We evaluated the rate of complications associated with catheterization and the risk of urethral lesions in girls with myelomeningocele treated with clean intermittent catheterization for a minimum of 10 years. MATERIALS AND METHODS: We examined the medical records of 31 females with myelomeningocele followed from the start of clean intermittent catheterization until age 11 to 20 years. Catheterization had been performed for a median of 15 years (range 10 to 19). Altogether, catheterization was used for a total of 459 patient-years. Noncoated polyvinyl chloride catheters were used in all cases. Anticholinergic treatment was given during 176 of the patient-years. RESULTS: Complications of catheterization were recorded in 13 patients on 20 occasions. Macroscopic hematuria was seen in 4 individuals. In 2 patients the hematuria was caused by urethral polyps that were cured by resection. Difficulties with catheterization occurred in 12 patients. The problems were solved by temporary use of lubrication or by other minor changes in management. There were no difficulties recorded after puberty. The risk of difficulties at catheterization doubled with the use of a Ch8 to Ch10 catheter compared to a Ch12 or larger catheter, and doubled during assisted clean intermittent catheterization compared to clean intermittent self-catheterization. CONCLUSIONS: There were remarkably few problems associated with clean intermittent catheterization in these females with myelomeningocele, despite long treatment periods and use of noncoated polyvinyl chloride catheters. Clean intermittent self-catheterization and large size catheters were associated with few complications.

Posterior intravaginal slingplasty with preservation of the uterus: a modified surgical technique in a young myelomeningocele patient.

We report a case of uterine prolapse in a young woman, treated by posterior intravaginal slingplasty with preservation of the uterus as a feasible and safe surgical procedure. Posterior intravaginal slingplasty is commonly used to correct vaginal vault prolapse, but may be a valuable alternative to correct uterine prolapse. We compare this technique to other techniques to correct uterine prolapse.
