Outcomes of laparoscopic management of multicompartmental pelvic organ prolapse.

BACKGROUND: Pelvic organ prolapse (POP) is an increasing medical problem with complex diagnostics and controversial surgical management. It causes a series of dysfunctions in the gynecological, urinary, and anorectal organs. Numerous procedures have been proposed to treat these conditions, but in recent years, ventral mesh rectocolposacropexy (VMRCS) has emerged as the procedure of choice for the surgical treatment of POP, especially by a laparoscopic approach. This surgical technique limits the risk of autonomic nerve damage, and the colpopexy allows the correction of concomitant prolapse of the middle compartment. However, symptoms derived from anterior compartment prolapse remain a major morbidity and sometimes require an additional procedure. The aim of this study is to evaluate the results of laparoscopic prosthetic rectocolposacropexy (LRCS) and colposacropexy (LCS) procedures performed to manage combined multicompartmental POP. METHODS: Between November 2008 and December 2017, 38 patients with symptomatic POP underwent rectocolposacropexy (RCS) or colposacropexy (CS) by a laparoscopic approach. Demographics, mortality, morbidity, hospital stay, and functional outcomes were retrospectively analyzed. RESULTS: The median operating time was 200 min (IQR 160-220). Additional simultaneous surgery for POP was performed in nine cases: five suburethral slings and four hysterectomies were performed. No mortality was recorded. The conversion rate was 7.89%. There were two intraoperative complications (5.26%): one enterotomy and one urinary bladder tear. Late complications occurred in 5.26% of cases. After a mean follow-up of 20 months, constipation was completely resolved or improved in 83.33% of patients, urinary stress incontinence was resolved or improved in 52.94%, and gynecological symptomatology was resolved or improved in 93.75%. The recurrence rate was 5.26%. CONCLUSIONS: Laparoscopic mesh rectocolposacropexy and colposacropexy are safe and effective techniques associated with very low morbidity. In the medium term, they provide good results for POP and associated symptoms, but urinary symptomology has a worse outcome.

The effect of a partially hydrolysed formula based on rice protein in the treatment of infants with cow's milk protein allergy.

Infants diagnosed with allergy to cow's milk protein (CMP) are fed extensively hydrolysed cow's milk formulas, modified soy formulas or even amino acid-based formulas. Hydrolysed rice protein infant formulas have become available and have been shown to be well tolerated by these infants. A prospective open, randomized clinical study to compare the clinical tolerance of a new hydrolysed rice protein formula (HRPF) with an extensively hydrolysed CMP formula (EHF) in the feeding of infants with IgE-mediated cow's milk allergy. Ninety-two infants (46 boys and 46 girls, mean age 4.3 months, range 1.1-10.1 months) diagnosed with IgE-mediated cow's milk allergy were enrolled in the study. Clinical tolerance to the formula products was tested. Clinical evaluation included skin prick tests with whole cow's milk, soya and rice as well as antigens of CMP (beta-lactoglobulin, alpha-lactalbumin, casein and bovine seroalbumin), HRPF and EHF and specific IgE determinations to CMP using CAP technology. Patients were randomized to receive either an EHF based on CMP or a new HRPF. Follow-up was at 3, 6, 12, 18 and 24 months. Growth parameters were measured at each visit. One infant showed immediate allergic reaction to EHF, but no reaction was shown by any infant in the HRPF group. The number of infants who did not become tolerant to CMP during the study was not statistically different between the two groups. Measurement of IgE levels of infants allergic to CMP during the study showed no significant differences between the two formula groups. Growth parameters were in the normal range and similar between groups. In this study, the HRPF was well tolerated by infants with moderate to severe symptoms of IgE-mediated CMP allergy. Children receiving this formula showed similar growth and development of clinical tolerance to those receiving an EHF. In accordance with current guidelines, this HRPF was tolerated by more than 90% of children with CMP allergy and therefore could provide an adequate and safe alternative to CMP-hydrolysed formulas for these infants.

Acute generalized exanthematous pustulosis due to tetrazepam.

Tetrazepam is a benzodiazepine that is widely used in Spain as a muscle relaxant, with occasional cutaneous side effects. We report a patient who developed a generalized pruriginous cutaneous reaction compatible with acute generalized exanthematous pustulosis (AGEP) due to tetrazepam. Patch tests with bromazepam, diazepam, and tetrazepam were negative at 48 and 72 hours; however, the tetrazepam patch showed a positive reaction at 10 days. Immunohistochemical studies revealed a mononuclear infiltrate composed of CD4+ and CD8+ T lymphocytes. Analysis of interleukin (IL) 8 expression by quantitative polymerase chain reaction revealed increased IL-8 mRNA levels in patch test-positive skin. Lymphoblast transformation test (LTT) was positive with tetrazepam but not with diazepam. Positive patch test and LTT suggested that tetrazepam-specific lymphocytes might be responsible for a T cell-mediated reaction. These results support previous data suggesting an important role for IL-8 and drug-specific T cells in the pathogenesis ofAGEP and imply that the reaction was specific to tetrazepam with no cross-reactivity to other benzodiazepines.

Cold urticaria and celiac disease.

Cold urticaria can be associated with blood and thyroid disorders, drugs, or infections. Celiac disease is an autoimmune enteropathy caused by permanent gluten intolerance. It is often associated with other autoimmune diseases, such as chronic idiopathic urticaria. Nevertheless, association with cold urticaria has not yet been described. A boy aged 3 years 8 months presented local urticaria-angioedema when exposed to cold temperatures. An ice cube test was positive and iron deficiency anemia was demonstrated. He later developed legume intolerance, rhinoconjunctivitis related to pollen sensitization, and asthma. Due to persistence of cold urticaria symptoms and refractory anemia, a test for immunoglobulin A autoantibodies to tissue transglutaminase and an intestinal biopsy were performed. Results of both tests were compatible with celiac disease.A study of human leukocyte antigen indicated a high risk phenotype (HLA, DR6/DR7; DQA 0501, 0201; DQB 0301, 0201). After 7 months of a gluten-free diet, the boy's anemia resolved and he is free of symptoms when exposed to cold. This is a first description of the possibility of an association between celiac disease and cold urticaria. A poor course of cold urticaria in the absence of evidence of another underlying condition should lead to suspicion of celiac disease.

Anisakis simplex allergy after eating chicken meat.

BACKGROUND: Allergic reactions to food can be produced by contaminants that induce sensitization. Among these, Anisakis simplex can cause seafood infestation, and allergic symptoms (urticaria-angioedema, anaphylaxis, and asthma) can follow the eating or handling of affected fish. Although seafood is the principal source of human infections by this parasite, we have found allergic symptoms in 8 patients previously diagnosed as having A simplex sensitization after they ate chicken meat. Chicken feed usually has a high proportion of fishmeal, which might possibly be contaminated by this nematode. OBJECTIVE: The aim of our study was to determine whether parasite proteins present in chicken meat could be responsible for the symptoms reported by these subjects. METHODS: We carried out in vivo tests (prick, bronchial challenge, and double-blind placebo-controlled challenge with meat chicken) in these 8 patients. We performed immunoblotting using the sera from the 8 patients and controls in order to detect A simplex sensitization. We also investigated the presence of A simplex proteins in sera from chickens fed with fishmeal and in other sera from chickens fed only with cereals. We excluded sensitization to other chicken nematodes by serologic methods. RESULTS: All 8 patients presented positive prick and challenges to A simplex. When we used serum from chickens fed with fishmeal as the antigen in blotting, patients 3, 4, 5, 6, 7, and 8 recognized a band of 16 kd, also obtained when using pools of fish-shellfish and A simplex larva. No detection was observed with sera from chickens fed with only cereals. CONCLUSION: We provide evidence, based on in vivo and in vitro tests, that subjects highly sensitized to A simplex can detect the presence of Anisakis species allergens in chicken meat.

Association between pollen hypersensitivity and edible vegetable allergy: a review.

Over the last three decades several authors have described the existence of an association between sensitivity to different pollens and sensitivity to diverse edible vegetables. An association between ragweed pollinosis and hypersensitivity to Cucurbitaceae vegetables (e.g., watermelon, melon, cucumber) and banana has been reported. Other authors have found a relationship between birch pollinosis and sensitization to hazelnut, apple, carrot, potato, kiwi and other vegetables. Additionally, several papers have shown the association between mugwort pollinosis and sensitization to celery, carrot, spices, nuts, mustard and Leguminoseae vegetables. Later, some studies showed association between grass pollinosis and sensitization to tomato, potato, green- pea, peanut, watermelon, melon, apple, orange and kiwi. Finally, an association between sensitization to plantain pollen and melon hypersensitivity was also described. The association between pollinosis and edible vegetable sensitization has been explained by the combination of different hypotheses, such as the following: 1) presence of lectins in edible vegetables; 2) existence of IgE to carbohydrates of the glycoproteins (cross-reactive carbohydrate determinants); and, 3) existence of common allergens between pollens and edible vegetables. Up to now three allergens have been identified as responsible for cross-reactivity in these associations: profilin, a 14 kd protein that regulates actin; Bet v 1, the 18 kd birch pollen allergen; and a 60-69 kd allergen. It is important to study in depth these associated sensitizations and the common allergens responsible for them in order to improve diagnostic methods and treatment of these syndromes.

Food allergies in Spain: causal allergens and diagnostic strategies.

A correct diagnosis of food allergy in the child is based on a careful medical history, together with the demonstration of specific IgE for the involved foods. However, before establishing an elimination diet, the "food-symptoms" relationship must be proven through a controlled challenge test.

[Video-laparoscopic placement of adjustable gastric banding (lap-band) in the treatment of morbid obesity. Preliminary results after 407 interventions]. / Aplicación de la bandeleta gástrica ajustable (lap-band) por videolaparoscopia en el tratamiento de la obesidad mórbida. Resultados preliminares tras 407 intervenciones.

INTRODUCTION: Morbid obesity is the most frequent nutritional disorder in developed countries. Bariatric surgery is one option for the definitive treatment of this disorder. We present 407 patients who underwent implantation of adjustable silicone gastric banding. Ninety-four percent of the patients were satisfied with the procedure and its results. MATERIAL AND METHOD: We performed a retrospective study in the Surgery Department of the Nordwestkrankenhaus teaching hospital of the University of Frankfurt. From April 1996 to January 2000 we performed laparoscopic placement of adjustable silicone gastric banding in 407 patients, using Kuzmak's technique. Mean body mass index was 49.1 and mean weight was 139.2 kg. We describe the patient selection method and provide a detailed description of the technique and its possible problems. RESULTS: There was no operative or postoperative mortality. None of the patients required conventional surgery. Mean operating time was 62 minutes (including operating times during the learning period). Mean hospital stay was 5 days. We performed 24 (5,89%) reinterventions: 11 for displacement, 2 for erosion, 4 for infection of the reservoir, 2 due to review of the reservoir to prevent penetration and 4 due to dilatations of the pouch (changing the banding from a retrogastric to a retroesophageal position); one patient requested removal of the banding. Follow-up was performed at months 1, 6, 9 and 12. Mean weight loss was 28 kg at 6 months and 54 kg at 1 year. Mean weight loss in patients followed-up for 2 years was 58 kg. A total of 94.9% of the patients were satisfied with the procedure. CONCLUSIONS: Laparoscopic implantation of adjustable gastric banding (Lap-Band) combines the aims of conventional gastroplasty with the advantages of laparoscopic surgery in terms of postoperative morbidity and minimal invasiveness.

[Incidence of allergy to cow's milk protein in the first year of life and its effect on consumption of hydrolyzed formulae]. / Incidencia de alergia a proteínas de leche de vaca en el primer año de vida y su repercusión en el consumo de hidrolizados.

OBJECTIVES: The aims of this study were to determine the incidence of allergy to cow's milk protein in infants and the cost of treatment with hydrolyzed formulae in the Autonomous Community of Madrid. PATIENTS AND METHODS: Infants with suspected adverse reaction to cow's milk protein born between March 1, 2000 and February 28, 2001 within the catchment area covered by the pediatric services of Hospital La Paz were studied. The diagnostic algorithm of allergy to cow's milk protein of our department was used. The theoretical consumption of hydrolyzed formulae in the treatment of allergic infants was calculated and extrapolated to the Community of Madrid. RESULTS: There were 5367 live births in the above-mentioned catchment area. Adverse reaction to cow's milk protein was suspected in 185 infants. Allergy to cow's milk protein was confirmed in 101 (54 %). The incidence of allergy to cow's milk protein was 101/5356 (1.9 %). In the same period there were 57 078 live births in the Autonomous Community of Madrid. The number of infants that might be allergic in one year would be 1084. The cost of hydrolyzed formulae per infant and year would be 1,585.72 Euros. Thus, the cost of hydrolyzed formulae in the 1084 allergic infants would be 1,718,922.9 Euros; in the 923 in whom allergy was ruled out, the cost would be 1,463,621.8 Euros. CONCLUSIONS: The incidence of allergy to cow's milk protein in the first year of life is at least 1.9 %. The correct diagnosis allows us to rule out allergy to cow's milk protein in almost half of the cases, thus avoiding the use of unnecessary substitutive diets involving a high cost.

A possible consequence of long-term elimination diet in IgE mediated subclinical food hypersensitivity.

IgE-mediated sub-clinical food hypersensitivity is recognized, but the hypersensitivity indicated is not always in accord with the observed symptoms. Study of 2 cases shows the inefficacy of a prescribed exclusion diet, without confirmation of the relationship between symptomatology and the food allergy. In addition, elimination of the foods aggravated the sensitivity of the patients and symptoms after provocation tests. Further studies must be made to decide whether there is a sound basis for long-term exclusion diets in sub-clinical food hypersensitivity.

Exercise-induced asthma in asthmatic children. Predisposing factors.

BACKGROUND: Exercise-induced bronchoconstriction (EIB) has a high prevalence in children with asthma, and this is a common problem, even in case of controlled asthma, because of the high levels of physical activity in the childhood. OBJECTIVES: The aim of our study was to identify factors associated with the development of EIB in children with controlled asthma. METHODS: We studied children evaluated for asthma. A personal and familiar history was collected from each patient to estimate asthma severity, precipitating factors, exercise ability, immunotherapy treatment and atopic familiar disorders. Skin prick tests for inhalant allergens, pulmonary function tests (PFTs) and exercise challenge test (ECT) measurements were realized in every patient. We used the Chi Squared test to compare qualitative variables, the Student's-t test for quantitative variables and a logistic regression analysis to estimate the independent effect of the variables. RESULTS: We evaluated 132 asthmatic patients. Eighty-two, 6 to 14 years old (average 110 +/- 36.9 months), were included in the study. Forty one have coughing or wheezing with exercise at least three months ago, in addition to a positive ECT; 9 of these children had solitary EIB (group A), and 32 (group B) had controlled chronic asthma, 27 intermittent and 5 moderately persistent. Forty one controlled asthmatic children, 39 intermittent, 1 mildly persistent and 1 moderately persistent (group C) had a good tolerance for exercise with a negative ECT. No differences were found in familiar history, asthma severity or evolution time in B vs C group. We found that 35 patients (42,68 %) patients were sensitized to indoor allergens: 24 (58,53 %) were patients suffering EIB and 11 (26,8 %) allowed to group C. Precipitating factors of asthma were in group B: respiratory infections in 19 cases, pollen in 20 and in 10 indoor allergens exposure. In group C: 14 patients had asthmatic symptoms with viral respiratory infections, 32 with pollen and 2 with indoor allergens exposure. A patient from group A had allergy rhinitis after exposure to cats. Allergy to indoor allergens demonstrated an direct association to EIB suffering (p = 0,026). Twenty six patients with allergic asthma followed pollen immunotherapy treatment, 7 of group B (33,3 %) and 19 (59,3 %) of group C. This treatment was inversely associated with EIB suffering (p = 0,048). A logistic regression analysis confirmed the independence of both variables as predisposing and protecting factors in EIB suffering. CONCLUSIONS: Allergy to indoor allergens might be considered a risk factor for EIB. Immunotherapy treatment could be a protective factor against the development of EIB in children with allergic asthma.

Food allergies and eosinophilic esophagitis--two case studies.

Eosinophilic esophagitis (EE) is a clinical-pathological disorder which is being increasingly diagnosed. It is etiologically associated with hypersensitivity to airborne allergens and/or dietary components. However, immediate hypersensitivity to foods has rarely been proven as the etiologic cause of the disorder. Two patients are presented with a history of rhinoconjunctivitis, allergic asthma, atopic dermatitis and food allergies which are currently under control and who show specific IgE to pulses and chicken respectively. These patients developed acute dysphagia and vomiting immediately after ingesting these foods and following appropriate examination were diagnosed as suffering from EE. The study also showed signs of blood hypereosinophilia while the esophageal manometry revealed a motor disorder characterized by aperistalsis and non-propulsive simultaneous waves affecting the lower two-thirds of the organ composed of smooth muscle. Topical treatment with fluticasone propionate was administered over a period of 3 months, in addition to a diet abstaining from the aforementioned foods and this led to remission of dysphagia and normalization of the endoscopic, histological and manometric studies of the esophagus. This situation remained stable for a considerable length of time after steroid treatment was discontinued, which showed that exposure to foods seemed to be the cause of the esophageal disorder. Similarly, allergies to inhalants and other digestive symptoms which appear upon immediate ingestion of the foods involved would not justify the sudden onset of dysphagia. We offer a pathophysiological explanation for the mechanisms of the disease based on the activation of eosinophils and mast cells by IgE and their ability to disturb the dynamic behavior of the neural and muscle components of the esophageal wall.

Relationship between pollinosis and fruit or vegetable sensitization.

The prevalence of vegetable sensitization in children with pollinosis (Group A; n = 48) and the prevalence of pollen sensitization in children with fruit or vegetable allergy (Group B; n = 42) were studied by means of prick-test and determination of serum specific IgE to several pollens, fruits and vegetables. Fifteen patients from Group A (31%) showed sensitivity to fruits and/or vegetables, but only three of them had any symptoms after ingestions. Twenty nine patients from Group B (69%) showed pollen sensitization, mainly to grass and Compositae pollen. An association was found between sensitivity to Compositae pollen and sensitivity to several fruits and vegetables (Compositae, Fagaceae, Brassica, Betulaceae and Leguminoseae).

Serum CD23 is not altered in gastroallergic anisakiasis, but correlates with the production of specific IgE and the amount of polyclonal stimulation.

BACKGROUND: Previous studies have shown elevated serum levels of the cytokines IL-4 and sCD23 in atopic patients and parasitic disease. Gastroallergic anisakiasis is an acute parasitic disease, accompanied by IgE-mediated clinical symptoms and an important increase of specific and total IgE. METHODS: Sixteen patients with acute urticaria/angioedema due to parasitism by Anisakis simplex after intake of raw or undercooked fish were selected, and serum samples were taken in the emergency room within 24 h (day 0; n=16), after 1 month (n=16), and after 6 months (n=10). Serum samples were studied for specific IgE against A. simplex, total IgE, sCD23, and IL-4. RESULTS: Mean values for sCD23 did not change in the observation period. Only 4/16 serum samples showed measurable IL-4 levels. Specific IgE and total IgE levels were found to be elevated after 1 month; after 6 months, they fell to nearly basal values. There was a positive correlation between sCD23 and specific IgE at day 0 and follow-up (r=0.55-0.69, P<0.026); a positive correlation between sCD23 and total IgE (r=0.54-0.62, P<0.056). Basal sCD23 could moderately predict the percentual increment of total IgE in the first month (r=0.56, P<0.038). CONCLUSION: Thus, it seems that interindividual variability of sCD23 is an important factor, with higher values predisposing to more production of unrelated IgE, independently of the parasite's action.

IgE crossreactivity between mugwort pollen (Artemisia vulgaris) and hazelnut (Abellana nux) in sera from patients with sensitivity to both extracts.

BACKGROUND: An association between sensitization to Compositae pollens and hypersensitivity to hazelnut has been previously described. There is no previous in vitro study about crossreactivity between mugwort pollen and hazelnut. OBJECTIVES: To study mugwort pollen and hazelnut allergens and to assess if there is IgE crossreactivity between mugwort pollen and hazelnut. METHODS: A serum pool formed by 28 individual sera with specific IgE to mugwort pollen and hazelnut was used to investigate IgE crossreactivity. RAST-inhibition, SDS-PAGE/IEF immunoblotting inhibition assays were performed by preincubation of the sera with mugwort pollen and hazelnut. RESULTS: RAST to hazelnut was inhibited up to 63% by mugwort pollen, but the mugwort pollen RAST was only inhibited up to 36% by hazelnut. In SDS-PAGE immunoblotting mugwort pollen showed nine allergens ranging from <16 to 65 kDa and hazelnut had four main allergens: 42 kDa, 17 kDa and <16 kDa (two bands). In the SDS-PAGE immunoblotting inhibition hazelnut partially inhibited all the mugwort pollen bands, except that with 19kDa, whereas mugwort pollen produced a nearly total inhibition of all the hazelnut allergens. In isoelectrofocusing immunoblotting mugwort pollen had two groups of allergens: pI 7.5-8.5 and pI 3.5-5.2 and hazelnut one group of allergens: pI 5.2-5.8. In the isoelectrofocusing immunoblotting inhibition hazelnut produced a partial inhibition of all the bands of mugwort pollen and mugwort pollen partially inhibited all the allergenic bands of hazelnut. CONCLUSIONS: The RAST and SDS-PAGE/IEF immunoblotting inhibition results provide evidence of IgE cross reactivity between mugwort pollen and hazelnut allergens. The inhibition of hazelnut by mugwort pollen is higher than the inhibition of mugwort pollen by hazelnut in both RAST inhibition and SDS-PAGE immunoblotting inhibition. These results suggest that mugwort pollen allergens would behave as primary immunogens in the association between sensitivity to mugwort pollen and hazelnut.

Allergic reactions following skin contact with fish.

We evaluated the clinical characteristics found in 29 children who showed allergic symptoms after direct and/or indirect contact with fish, from 197 children diagnosed with IgE-mediated fish hypersensitivity. Allergic reactions to fish through ingestion began in most patients (79%) within the first 24 months of life. All the patients showed cutaneous symptoms, either alone or associated with other clinical manifestations. Whiff and hake were the species more frequently implicated in eliciting clinical manifestations upon ingestion. After diagnosis, all patients were placed on a strict fish avoidance diet. During this period of avoidance, 29 patients reported allergic reactions (mean age 5 years, 6 months; SD 4 years, 2 months) after incidental skin contact with fish. Clinical manifestations after touching fish were only cutaneous in 28 of the 29 studied patients. One showed local urticaria with wheezing. The majority reported two or more episodes. Incidental skin contact with fish could play an important role in accidental encounters with fish particles in children on a fish avoidance diet for fish IgE-mediated hypersensitivity. Such exposures could result in immunologic immediate contact reactions and in some cases could lead to systemic reactions (contact urticaria syndrome).

In vitro detection of specific IgE antibodies to erythromycin.

BACKGROUND: In vitro tests for detecting drug-specific IgE would be useful in identifying patients at risk for immediate hypersensitivity reactions to therapeutic doses of a drug. OBJECTIVE: We attempted to verify that IgE-mediated reactions to erythromycin occur and to identify IgE antibodies specific for erythromycin in serum from a patient who had urticaria immediately after administration of the drug. METHODS: Skin prick testing was performed on the patient and five control subjects. Serum from the patient, pooled sera from nonatopic subjects allergic to common aeroallergens, and cord blood controls were analyzed for erythromycin-specific IgE by radioimmunoassay. Sepharose (Pharmacia, Uppsala, Sweden) was used as solid phase covalently linked to erythromycin. RESULTS: We were able to detect erythromycin-specific IgE antibodies in serum from the patient who had an allergic reaction to this antibiotic, but specific IgE could not be detected in control sera. CONCLUSION: Immunologic IgE-mediated reactions to erythromycin do occur, and in vitro diagnosis of such reactions can be made by using Sepharose as a solid phase covalently linked to this drug.
