A Prospective Study of Costs Associated With the Evaluation of Allergic Reactions to Radiological Contrast Media.

BACKGROUND AND OBJECTIVE: The prevalence of hypersensitivity reactions to radiological contrast media (RCM) is increasing owing to the improved performance of diagnostic and therapeutic tests that require RCMs. Objective: We carried out a year-long real-life observational study to prospectively evaluate patients referred to the allergy department from primary care, the emergency department, and other specialties with suspected moderate-to-severe RCM hypersensitivity reactions. METHODS: To study the costs of evaluating RCM hypersensitivity reactions, we systematically recorded direct and indirect costs. RESULTS: Sixty-nine patients with previous reactions to RCM were evaluated in the allergy department from June 1, 2017, to May 31, 2018.Total direct health care costs were €10 715.84, with a mean (SD) cost per patient of €155.30 (77.08). Specifically, direct non-health care costs reached €1605.42 (mean, €23.27 [41.14]), and indirect costs were €6490.85 (mean, €94.07 [110.61]). In summary, the total cost was €18 812.11, that is, a mean cost of €272.64 (164.77). CONCLUSION: Our study shows that the costs of an elective evaluation of hypersensitivity reactions to RCM are low, thus confirming that correct and safe management of affected patients are cost-effective. Therefore, our efforts should be directed toward ensuring the necessary logistics.

A Comprehensive Prospective Study of the Costs Associated With Evaluation of ß-Lactam Allergy.

BACKGROUND AND OBJECTIVE: Being labeled as allergic to penicillin (unverified ß-lactam allergy) can result in patients receiving broader-spectrum antibiotics than necessary that may be more toxic, less effective, and/or more expensive than alternative options. Objective: We aimed to evaluate the real costs of evaluating ß-lactam allergy. METHODS: We performed a prospective real-life observational study designed to evaluate all adult patients who consulted for suspected ß-lactam allergy over a 1-year period. Direct and indirect costs were systematically recorded. Direct health costs were calculated based on the number of visits and all additional and diagnostic tests performed, direct nonhealth costs based on the number of visits and the distance from their homes to the Allergy Department, and indirect costs based on absenteeism. RESULTS: A total of 296 patients with suspected allergy to ß-lactams were evaluated in our outpatient clinic from June 1, 2017 to May 31, 2018. Total direct health care costs were €28 176.70, with a mean (SD) cost of €95.19 (37.20). Direct nonhealth costs reached €6551.73, that is, €22.13 (40.44) per patient. Indirect health costs reached €20 769.20, with a mean of €70.17 (127.40). In summary, the total cost was €55 497.63, that is, a cost per patient of €187.49 (148.14). CONCLUSIONS: When all possible costs are taken into account, the evaluation of ß-lactam allergy is not expensive and can reduce future expense arising from unnecessary use of more expensive and less effective antibiotics.

Consensus document on dog and cat allergy.

The prevalence of sensitization to dogs and cats varies by country, exposure time and predisposition to atopy. It is estimated that 26% of European adults coming to the clinic for suspected allergy to inhalant allergens are sensitized to cats and 27% to dogs. This document is intended to be a useful tool for clinicians involved in the management of people with dog or cat allergy. It was prepared from a consensus process based on the RAND/UCLA method. Following a literature review, it proposes various recommendations concerning the diagnosis and treatment of these patients, grounded in evidence and clinical experience. The diagnosis of dog and cat allergy is based on a medical history and physical examination that are consistent with each other and is confirmed with positive results on specific IgE skin tests. Sometimes, especially in polysensitized patients, molecular diagnosis is strongly recommended. Although the most advisable measure would be to avoid the animal, this is often impossible and associated with a major emotional impact. Furthermore, indirect exposure to allergens occurs in environments in which animals are not present. Immunotherapy is emerging as a potential solution to this problem, although further supporting studies are needed.

Selective hypersensitivity to boiled razor shell.

Many types of seafood require cooking before ingestion and it has been demonstrated that this cooking process may affect the antigenicity and allergenicity of the food. We describe a case of anaphylaxis caused by selective sensitization to razor shell, a mollusc. In vivo and in vitro studies confirmed sensitization to boiled razor shell. Analysis of the nature of the allergen yielded results that were consistent with the findings of other authors and suggested that allergens involved in seafood allergy are commonly high molecular weight proteins that, in most cases, are heat stable.

[Urinary stress incontinence: surgical experience in our center]. / Incontinencia de esfuerzo: experiencia quirúrgica en nuestro centro.

INTRODUCTION: For the treatment of the urinary stress incontinence, there are many techniques, and today the gold standard is that described by Burch. We compared the global and each technique results about rates of postoperative continence and complications seen in our experience. MATERIALS AND METHODS: We made a retrospective analysis of 292 women that have the first surgery for urinary stress incontinence in our centre, between 1991 and 2006. We considered cure the patient who did not have any level of incontinence postoperative, we made a Kaplan-Meier analysis for the postoperative continence evaluation. Besides we studied the behaviour of the postoperative complications found. RESULTS: Mean age was 53.6 years old, and mean time of follow up was 15.6 months. The vaginal techniques were the most practised (138), followed by the TVT (57), abdominal Burch (38), vaginal wall Sling (33), and the less was the laparoscopic Burch (26). The best rates of postoperative continence after 2 years were observed in the patients treated by TVT (87.6%), then with vaginal wall Sling (84.9%), laparoscopic Burch (59.3%), abdominal Burch (59.1%), and the worst with vaginal techniques (48.2%) (p = 0.007). We found more urgency and urge incontinence in the patients treated by TVT (36.8% y 21.1% respectively), and postoperative pain with vaginal techniques (36.2%). Postoperative urine retention and postoperative high residual urine more with the vaginal wall sling (54.5%) and vaginal techniques (26.1%) respectively. CONCLUSIONS: We have the best results for the incontinence treatment in our population with the TVT technique.

Rhinitis and asthma due to ranitidine.

Few reports exist on allergic reactions to ranitidine. We present a case of bronchospastic reaction to ranitidine occurred during a drug challenge test. After administration of a therapeutic dose of ranitidine, the patient showed dyspnea, cough and bronchospasm in all the lung fields. Personal respiratory background was negative for respiratory disease and asthma. On reviewing the literature we found no reports of bronchospastic reaction to ranitidine. Quickness and the clinical characteristics of the adverse reaction suggest a pathogenic mechanism of immediate-type hypersensitivity.

Celecoxib, a highly selective COX-2 inhibitor, is safe in aspirin-induced asthma patients.

BACKGROUND: In 5-10% of adult patients with asthma, aspirin and most other nonsteroidal anti-inflammatory drugs (NSAIDs) precipitate acute asthmatic attacks. Therefore, choosing an alternative anti-inflammatory agent for patients who have suffered adverse reactions to a nonsteroidal anti-inflammatory agent is a common problem in clinical practice. The discoveries that cyclooxygenase COX-2 is an inducible form of COX involved in inflammation and COX-1 is the major isoform responsible for the production of prostaglandins have provided a reasonable basis for the development of specific COX-2 inhibitors as a new class of anti-inflammatory agents. OBJECTIVE: The purpose of this study is to demonstrate that celecoxib, a specific inhibitor of COX-2, does not cause asthmatic attacks in patients with aspirin and/or other nonsteroidal anti-inflammatory drug-induced asthma. METHODS: We studied 33 patients, all of whom suffered from asthma induced by at least two different NSAID drugs. They were challenged in a single-blind manner with different doses of celecoxib on three different days, until either the therapeutic dose of 200 mg or intolerance was reached. Each patient was rechallenged with 200 mg celecoxib seven days later if no evidence of intolerance was previously observed. RESULTS: Celecoxib 200 mg was proven to be well tolerated in all 30 three aspirin- and NSAID-induced asthma patients. CONCLUSION: Our study appears to demonstrate that celecoxib is a suitable NSAID in aspirin-induced and/or nonsteroidal anti-inflammatory drug-induced asthma patients.

[Pelvic solid masses of uncertain etiology. A clinical case]. / Masas sólidas pelvianas de etiología incierta. Caso clínico.

We report the case of a 73 year old male with a bulky endovesical mass infiltrating near organs at the radiologic studies and urinary obstruction. We specify the diagnostic tests which end in the diagnosis of giant benign prostatic hyperplasia. Regarding the case, we consider the causes of solic pelvic masses and the diagnostic methods available, making a stand on the paramount importance of the hystologic exam.

[Priapism secondary to a bilateral abscess of the corpora cavernosa]. / Priapismo secundario a absceso bilateral de cuerpos cavernosos.

Presentation of an exceptional case of priapism in an 82-year-old male, secondary to primary bilateral abscess corpus cavernosum. Diagnosis was reached through aspiration puncture and pus drainage, which also allowed the resolution of the condition. After a literature review, no similar case was found. This was a painful, long-lasting erection that resulted from corpus cavernosum repletion with purulent material instead of blood.

[TVT and TOT for surgical correction of female stress urinary incontinence. Comparison between techniques]. / TVT y TOT para la corrección quirúrgica de la incontinencia femenina de stress. Comparacion de ambas técnicas.

OBJECTIVES: Retrospective analysis of a series of patients with stress urinary incontinence that underwent surgery in our department, by means of the TVT and TOT techniques. We evaluate post operative continence, considering "cured" the patient with complete continence and "failure" any type of involuntary stress urine leak, independently of its severity registering the time of its appearance. For this purpose we used the Kaplan-Meier analysis comparing both techniques with the Breslow test. Additionally, postoperative complications were evaluated. RESULTS: 128 patients who underwent surgery by TVT (69 patients, 53.9%) and TOT (59 patients, 46.1%). Mean age was 54.4 years for TVT (95% CI 52.0-56.8) and 59 years for TOT (95% CI 55.9-62.1). Mean follow-up time was 18.7 months for TVT (95% CI 15.6-21.9) and 7.4 months for TOT (95% CI 5.8-8.9). Overall continence rate was 86.7%, 88.4% for TVT and 84.7% for TOT The probability of being continent six months after surgery was 89.1% for TVT and 78.2% for TOT (no significant differences, p = 0.31), with almost all failures within the first six months after surgery. TVT was more frecuently associated with urgency symptoms (33.3%, p = 0.001) and urge incontinence (18.8%,p = 0.16), urinary retention (11.6%, p = 0.38), and prevesical hematoma requiring mesh retrieval. Greater post operative pain was observed with TOT (20.3%, p = 0.005). CONCLUSIONS: Our results evidence a similar efficacy with both techniques, with the failures appearing over the first months after surgery. Complications of the voiding urgency type are significantly more frequent with TVT.

Immunotherapy with depigmented glutaraldehyde-polymerized extracts: changes in quality of life.

BACKGROUND: Immunotherapy (IT) with modified allergens reduces allergic rhinitis (AR) symptoms and medications requirements. Improvement of quality of life (QOL) is a key point in the treatment of AR. The aim of this study was to provide evidence of changes related to the patient's QOL (well-being) induced by a modified (depigmented glutaraldehyde-polymerized) therapeutic vaccine and of its safety. MATERIAL AND METHODS: Fifty-three patients with a well-documented clinical history of seasonal AR sensitized to Dactylis glomerata and Olea europaea pollens were included in a randomized clinical trial. Twenty-five patients (Group-A) received a mixture of D. glomerata and O. europaea pollen extracts and 28 patients received placebo (group-C). Any adverse event was recorded and graded in accordance with EAACI guidelines. RQLQ was recorded before the treatment (pollen season 2000) and after 1 year of treatment (pollen season 2001). Dose-response skin prick test with each allergen extract was conducted at baseline and at the end of the study. RESULTS: Each patient received 17 injections during this period. All patients completed the trial and no systemic adverse reactions were recorded. Symptom scores (P<0.001) and medication requirements (P<0.001) were significantly reduced in the IT group during the pollen season. This patient group also experienced greater and statistically significant improvement in overall RQLQ score and in five of the seven domains, all of them surpassing the threshold of 'minimal important difference' of 0.5 points. CONCLUSIONS: Results of this study provided evidence that IT with depigmented, glutaraldehyde-modified allergen extracts was well-tolerated and added beneficial effects to AR treatment in pollen allergic patients eliciting an improvement in QOL enough to justify a change in the patient's treatment.

Angioedema induced by inhalation of vapours from cooked white bean in a child.

BACKGROUND: There are few references of allergic reaction to beans in childhood. We report the case of a seven years old boy who suffered from angioedema associated to inhalation of vapours from cooked white bean. METHODS: skin prick tests (SPT) were performed by prick-by-prick with cooked white bean and legumes. It was also determined total IgE and specific IgE antibodies to bean and legumes with the use of the CAP enzymo-immunoassay. Subsequently, a oral challenge test was carried out with white bean. RESULTS: The prick-by-prick with white bean was positive in our case, and negative in ten controls patients. Specific IgE in patient serum, assayed by CAP was positive for white bean and green bean. The patient developed angioedema after ingestion cooked white bean. CONCLUSION: we demonstrated a type I hypersensitivity to white bean in a seven years old child by SPT, specific IgE antibodies and challenge test.

[Condylomata acuminata in childhood: report of a case]. / Condilomas acuminados en la infancia: presentación de un caso.

OBJECTIVE: To report an additional case of condylomata acuminata in a child, review the literature and discuss the medicolegal implications due to the possibility of sexual abuse. METHODS/RESULTS: The diagnosis, treatment and clinical course of the lesions are discussed. Psychological evaluation of the child discarded infection by sexual transmission. CONCLUSION: Condylomata acuminata in children represent a diagnostic difficulty due to the possibility of infection by sexual transmission, although it should be taken into account that non sexual transmission of this sexually transmissible disease is very frequent in childhood.

[Malignant Leydig cell tumor. Report of a case and review of the literature]. / Tumor maligno de células de Leydig. Presentación de un caso y revisión de la literatura.

OBJECTIVE: To report an additional case of malignant Leydig cell tumor of the testis. The clinical, hormonal and histological criteria for malignancy are analyzed and the different therapeutic options are discussed. METHODS/RESULTS: A 75-year-old male presented with a painful testicular tumor, dyspnea and generalized syndrome. The chest film showed multiple bilateral metastatic pulmonary lesions. Pathological analysis disclosed malignant Leydig cell tumor. The patient died one month after orchidectomy due to the neoplasm. CONCLUSIONS: Metastatic Leydig cell tumor is uncommon. To date, no available treatment can significantly alter the course of the disease.

[The usefulness of micturition flow acceleration in the diagnosis of bladder instability]. / Utilidad de la aceleración del flujo miccional en el diagnóstico de la inestabilidad vesical.

The acceleration of flow rate (ml/sg2) is a urodynamic parameter derived from free flow uroflowmetry. The present study was conducted to determine the role of this new parameter as an alternative to the standard filling cystometry in the diagnosis of detrusor instability in nocturnal enuresis, prostatism and female urinary incontinence. We have observed that it is not a useful parameter due to the large overlapping of the patients with unstable and normal bladder. For this reason it is not possible to establish significant predictive values.
