First report of anaphylactic reaction after fig (Ficus carica) ingestion.

We report an anaphylactic reaction which occurred very shortly after ingestion of a fresh fig. The IgE-dependent mechanism was demonstrated on the basis of positivity of the prick test performed with fresh fig (Ficus carica) extract. In addition, we were able to detect specific IgE to the same extract in the serum. The patient did not demonstrate sensitization to other common allergens involved in respiratory and food allergies. However, detection of specific IgE to F. benjamina indicated a sensitization to weeping fig. The CAP F. benjamina was partially inhibited by preincubation of the serum with fig extract, suggesting that these two species of Ficus share some common allergens. In this context, the assumption can be made that weeping fig was responsible for the initial sensitization in this patient.

Oral allergy syndrome to fig.

BACKGROUND: The few cases of food allergy to fig reported to date, whose main manifestations were anaphylactic reactions, have been related to a cross-sensitisation to weeping fig (Ficus benjamina) or to the 'latex-fruit syndrome'. Here we report on two cases of the oral allergy syndrome (OAS) to fig in patients whose main allergic manifestations were related to sensitisation to grass and birch pollens. METHODS: The patients were characterised by clinical history, skin prick tests (SPT) with commercial and in-house extracts, prick-by-prick test, specific IgE measurements and challenge tests. PBS-soluble and insoluble extracts of both fig skin and pulp were examined for the presence of potential allergens by IgE immunoblotting. RESULTS: Both patients showed OAS followed by respiratory symptoms when challenged with fig. They were negative in both specific IgE detection and SPT with commercial extracts of fig and many other plant materials, including F. benjamina and Hevea Brasiliensis, while grass and birch pollens gave positive results. Prick-by-prick tests and SPT with in-house extracts indicated that the fig skin had a much higher allergenicity than the pulp. Despite negative IgE detection by the CAP assay, immunoblotting experiments showed that potential fig allergens were PBS-soluble and present only in the skin of the fruit. CONCLUSIONS: OAS to fig followed by respiratory symptoms can be present in patients not sensitised to weeping fig or having the latex-fruit syndrome. Different parts of the fig can have different allergenicities, the most important allergens being proteins related to the skin of the fruit. Improved commercial fig extracts to be used for the diagnosis of this type of allergy have to be developed.

Effects of early experience on voluntary intake of low-quality roughage by sheep.

This study determined 1) how experience early in life with cured weeping lovegrass (Eragrostis curvula) (low-quality roughage) or fresh oats (Avena sativa) (high-quality roughage) affected consumption of low- or high-quality roughage by lambs later in life and 2) whether this early dietary experience affected passage of undigested residues through the digestive tract and digestion of low-quality roughage. From 1 to 5 mo of age, experienced lambs (EL) were grazing cured weeping lovegrass, whereas inexperienced lambs (IL) were grazing fresh oats. Immediately after exposure, in Trial 1 lambs were fed sorghum (Sorghum bicolor) hay (low-quality roughage) supplemented with a protein concentrate. In Trial 2 lambs were offered sorghum only. Finally, in Trial 3 lambs were offered a choice between sorghum and alfalfa hay. When the sorghum was supplemented with protein there was no difference (P > .05) between treatments in intake of sorghum, but when the supplement was withheld in Trial 2, EL ingested 20% more (P < .01) sorghum than IL. When given a choice between sorghum and alfalfa, EL ingested 2.5 times more (P < .01) sorghum than IL. The apparent digestibility of sorghum was 4.5% higher (P < .01) in EL than in IL, whereas passage of undigested matter through the digestive tract was similar (P > .05). The results show that early dietary experience can have a significant effect on consumption of low-quality roughage and diet selection in free-choice situations.

Factors affecting calcium lactate and liquid expulsion defects in Cheddar cheese.

This paper summarizes the results of 2 studies designed to investigate the influence of several manufacturing and curing treatments on the appearance of Cheddar cheese defects. Specifically, 2 defects, calcium lactate crystal formation and the expulsion of free liquid (weeping) were monitored in Cheddar cheese. Both studies were conducted at a commercial cheese manufacturing facility that produces Cheddar in 18.14-kg (40-lb) blocks. In the first study we monitored cheese calcium, both total and soluble during manufacture and early curing. In the second study we measured cheese pH from 3 d through 8 mo, as well as some factors that are influenced by cheese pH. Early cheese pH (3 d to 7 d) patterns were used to select vats of cheese for retail packaging. Mild Cheddar packaged at 30 d postmanufacture and sharp Cheddar packaged at 8 mo postmanufacture from the same vats were monitored for the incidence and severity of the defects. Our results indicated that factors measured in early stages of manufacture and curing (less than 7 d) such as cheese pH at mill, lactic acid concentration, nonprotein nitrogen, and calcium (total and soluble) in cheese did not correlate with the appearance of either calcium lactate or expulsion of free liquid in packaged cheeses. Factors including pH, lactic acid concentrations, and soluble calcium measured during curing (greater than 7 d) of cheese were found to be statistically significant in the development of defects and appeared to be associated with use of specific starter culture groups. In the study, 5 different starter culture groups, each consisting of a 4-strain blend of Lactococcus lactis ssp. cremoris and Lactococcus lactis ssp. lactis, were used to manufacture the cheeses. Cheese manufactured with one particular culture group showed no incidence of calcium lactate crystal formation or weeping during curing and shelf-life of cheeses in this study. This starter group also generated the least amount of pH change in cheese during the first month of curing. From these results we conclude that starter culture group, more than any other factor measured, played an important role in the development of calcium lactate and liquid expulsion defects in Cheddar cheese. Starter culture group appeared to strongly influence cheese pH, lactic acid, and soluble calcium concentrations during curing and storage.

Occurrence of selected foodborne pathogens on poultry and poultry giblets from small retail processing operations in Trinidad.

We conducted a study to determine quantitatively and qualitatively the presence of Campylobacter spp., Escherichia coli, staphylococci, total coliforms, total aerobic bacteria, and Salmonella on broiler carcasses from selected small retail processors in Trinidad. We used standard media and procedures for detection and quantification. All carcass and weep samples were positive for aerobic bacteria, E. coli, total coliforms, and staphylococci. Significant differences in the mean counts of aerobic bacteria were observed for samples of carcass (P = 0.001), weep (P = 0.038), and liver and heart (P = 0.017). There was a significant difference (P < 0.05) in the prevalence of E. coli and Campylobacter for liver and heart samples and gizzard samples across various areas (health divisions) in Trinidad and for Campylobacter jejuni and Campylobacter coli for offal samples. The prevalence of Salmonella in carcass, drip, gizzard, and liver and heart samples was 7.3, 3.1, 2.1, and 1.0%, respectively, and three serotypes, Salmonella Kiambu (53.8%), Salmonella Kentucky (38.5%), and Salmonella Mbandaka (7.7%) were isolated. Of the six groups of microbes considered with respect to sale activity, the differences in the prevalence of Campylobacter in medium-activity sale shops (95.8%) and low-activity sale shops (83.3%) and the mean counts of staphylococci for medium-activity sale shops (5.5 +/- 0.9) and low-activity sale shops (5.1 +/- 0.8) were statistically significant (P < 0.05). Carcasses rinsed in a stagnant system had a significantly higher (P < 0.05) prevalence (92.3%) and mean count per milliliter (3.1 +/- 0.7) for Campylobacter compared with 77.8% and 2.7 +/- 0.7 for shops that rinsed with constantly running water. The frequency of rinse water change significantly (P = 0.04) affected the prevalence of Salmonella on carcasses. It is recommended that a quality control system be introduced for these shops, particularly with respect to evisceration and rinsing practices.

[Reconstruction of the lacrimal ducts: results in a series of 102 cases (author's transl)].

Surgery of the lacrimal appartus falls into the realm of a paradox: paradoxical because of the means employed to repair an excretory apparatus which is not absolutely indispensable; paradoxical because of the great difficulty encountered in assessing results in operated patients with: obstruction without weeping or; weeping without obstruction. The indication for operation is related to two factors: that of the act itself--valid in new lesions, debatable in old lesions, doubtful in relapses; that of the technique used, which in the authors' view is mainly a function of the state of the lacrimal sac. An objective analysis of a series of 102 cases strengthened the authors' opinions but with a feeling of circumspection tainted with deception.

[Effect of chamomile on wound healing--a clinical double-blind study].

In a double-blind trial, the therapeutic efficacy of chamomile extract was tested on 14 patients. As objective parameters served the epithelial and drying effect on weeping wound area after dermabrasion of tattoos. The period of the healing and drying process was judged by the doctor. The decrease of the weeping wound area as well as the drying tendency was statistically significant.

[Results of a multi-center, international clinical trial of difluocortolone valerate (Nerisona)].

The new corticosteroid diflucortolone valerate was clinically investigated in an international, multi-centre trial by a total of 162 dermatologists in 22 countries in more than 6,285 patients with inflammatory and allergic skin diseases. Depending on the condition of the skin, diflucortolone valerate was applied as a cream, ointment or fatty ointment at a concentration of 0.1%. Most of the patients treated with the cream displayed weeping skin conditions. The ointment was used mainly in patients with neither weeping nor very dry skin conditions, while the fatty ointment was employed mainly in very dry processes. After the exclusion of invalid record forms, 5,578 cases remained for computer evaluation. The results confirm that the success rate in local corticoid therapy can be improved by adapting the base to the respective skin condition. The forms investigated were found to be highly effective preparations with excellent skin tolerance. They can be placed on a par with today's leading topical corticoid preparations.

[The use of difluocortolone valerate in various dermatoses].

Diflucortolone valerate was clinically investigated as a fatty ointment in 30 dermatological patients. Although this form of application is a special presentation for the treatment of very dry dermatoses, patients with not so dry and weeping dermatoses were also treated in this trial, the object being to include the role played by the vehicle in the results of therapy. Very good to good results were achieved in 80% of the cases treated, while the result was observed to be poor in only 10% of the cases. This latter percentage is comprised for the greater part of patients who had previously been treated with other corticoids and of patients with weeping dermatoses.

Milker's nodules. Pathogenesis, tissue culture, electron microscopy, and calf inoculation.

We report the occurence of milker's nodules in nine patients. In man, the disease goes through maculopapular, target, acute weeping, nodular, papillo-matous, and regressive stages. Papular and papillomatous stages were noted following vaccination of a calf with material prepared from a human lesion. A viral agent was isolated in cultures of bovine kidney cells and human skin fibroblast cells. Cytoplasmic inclusions were frequently seen in the infected bovine kidney cells. Electron microscopy revealed viroplasm, partially encapsulated viroplasm, encapsulated viroplasm, and oval particles with spires around the outside.

Postendoscopic Zenker esophagodiverticulostomy leaks associated with a specific stapler cartridge.

OBJECTIVE: To determine the cause of postoperative leaks in 2 patients with Zenker diverticula treated with endoscopic staple-assisted esophagodiverticulostomy. DESIGN: Medical chart review and simulated surgery. SETTING: Teaching hospital. PATIENTS AND METHODS: Two case reports of postoperative leaks in patients treated with endoscopic staple-assisted esophagodiverticulostomy and experimental simulated surgery to investigate the possible cause of this complication. Use of a TR45B, 3.5-mm cartridge for an Endopath ETS Flex45 Endoscopic Articulation Linear Cutter stapler was associated with complications, whereas use of a TR45W, 2.5-mm cartridge in the same stapler was not. RESULTS: In a simulated surgery model, the 3.5-mm cartridge staple line leaked from the incision apex with pressure of less than 20 cm H(2)O, whereas the apex remained dry when using the 2.5-mm cartridge. When pressure was increased to 30 cm H(2)O, the staple line of the 2.5-mm cartridge had diffuse weeping of fluid but no focal, apical leak. CONCLUSIONS: Endoscopic staple-assisted esophagodiverticulostomy continues to be a relatively safe procedure; however, to provide maximum safety at the apex, the surgeon needs to be aware of stapler cartridge differences.

Behavioral changes in pediatric intensive care units.

OBJECTIVE: The purposes of this study were to compare the frequency and severity of manifestations of anxiety, depression, delirium, and withdrawal in pediatric patients hospitalized in intensive care unit vs ward settings and to evaluate the impact of preexisting psychopathologic disorders on the expression of these symptoms. RESEARCH DESIGN: Prospective patient series. SETTING: Tertiary care pediatric center. PATIENTS: Forty-three subjects aged 6 to 17 years hospitalized in either the pediatric or cardiovascular intensive care unit (n = 18) or on the general wards (n = 25) were recruited to participate. Subjects were excluded if their parents were unavailable for diagnostic interview or if they could not answer interview questions themselves. SELECTION PROCEDURES: Consecutive sample. INTERVENTIONS: None. MEASUREMENTS AND RESULTS: The Hospital Observed Behavior Scale, developed for this study, was used to describe objectively subjects' manifestations of anxiety, depression, delirium, and withdrawal. The Diagnostic Interview for Children and Adolescents and Diagnostic Interview for Children and Adolescents-Parents were used to determine the presence of preexisting psychopathologic disorders. As measured by the Hospital Observed Behavior Scale, subjects in the intensive care unit exhibited apprehension, anxiety, detachment, sadness, and weeping more often than did patients in the ward. Behavior was also significantly influenced by severity of illness, duration of hospitalization, number of previous hospitalizations, and presence of a preexisting anxiety or mood disorder. We found the Hospital Observed Behavior Scale to have good interrater reliability. CONCLUSIONS: Our data indicate that critically ill children in the intensive care unit, children with prolonged or repeated hospitalizations, and children with preexisting anxiety and mood disorders are at greater risk than other hospitalized pediatric patients for psychological trauma and/or behavior problems that may warrant psychiatric intervention. The Hospital Observed Behavior Scale is a reliable tool to quantitate behaviors in hospitalized children.

Morphological characteristics and terminating patterns of masseteric neurons of the mesencephalic trigeminal nucleus in the rat: an intracellular horseradish peroxidase labeling study.

In order to study the morphological characteristics and terminating patterns of the neurons of the trigeminal mesencephalic nucleus (Vme), 55 masseteric neurons in Vme in the rat were stained by intracellular injection of horseradish peroxidase (HRP). Labeled cells were distributed throughout the nucleus. These neurons were divided into three types: uni- or pseudounipolar (type A, n = 43), bipolar (type B, n = 5), and multipolar cells (type C, n = 7). Each type was further divided into two subtypes according to the largest diameter of the perikarya (type a greater than or equal to 30 microns, type b less than 30 microns). The central processes of type Aa neurons projected to the following three groups of target nuclei: 1) nuclei functioning as interneurons, including supratrigeminal nucleus (Vsup), intertrigeminal nucleus (Vint), juxta-trigeminal region (Vjux), and parvicellular nucleus of the pontomedullary reticular formation (PcRF); 2) motor nuclei, including the trigeminal motor nucleus (Vmo), accessory facial nucleus (NVIIacs), accessory abducens nucleus (NVIacs), and a small number of labeled axons in the oculomotor nucleus and trochlear nucleus; 3) sensory nuclei, including the dorsomedial part of the principal trigeminal sensory nucleus (Vpdm) and the dorsomedial part of subnucleus oralis of the trigeminal spinal nucleus (Vodm). Labeled processes were dense in the Vsup, Vmo, and Vpdm. The proprioceptive pathway of the fifth nerve is discussed. Direct projections from type Aa neurons of Vme to the Vpdm and dorsolateral part of the Vsup contribute to conduction of the proprioceptive information from spindles of masticatory muscle to the contralateral thalamus in the rat. Different axon morphology, distribution, terminal branch density, and terminating patterns of type Aa neurons were noted in different functional groups of the projecting nuclei, especially in the Vsup, Vmo, and Vpdm. The highest terminal branching density, the most extensive distribution, and two different types of branching patterns (claw-like and comb-like) were observed in Vsup. Selective distribution and single-beaded or "Y"-shaped terminal branches were observed in Vmo. In the Vppdm the axonal branches were sparser than in the Vsup or Vmo, and had an arrangement like the branches of a weeping willow tree. These characteristics of anatomical organization might be related to the function of each projecting nucleus.

Genetic mapping with dispersed repeated sequences in the rice blast fungus: mapping the SMO locus.

The SMO genetic locus in strains of the fungus Magnaporthe grisea that infect weeping lovegrass, directs the formation of correct cell shapes in asexual spores, infection structures, and asci. We have identified and characterized a Smo- strain of M. grisea that infects rice. The smo mutation in this strain segregates as a single gene mutation and is allelic to previously identified smo alleles. A marked reduction in pathogenicity co-segregates with the Smo- phenotype, suggesting that the SMO locus plays a role in rice pathogenicity. A family of dispersed repeated DNA sequences, called MGR, have been discovered in the nuclear DNA of M. grisea rice pathogens. Genetic crosses between Smo- rice pathogens and Smo+ non-rice pathogens were used to follow the segregation of the SMO locus and individual MGR sequences. Using DNA blot analysis with cloned MGR hybridization probes, we mapped the SMO locus to a chromosomal region flanked by two closely linked MGR sequences. We demonstrated that the copy number of MGR sequences could be reduced in subsequent crosses to non-rice pathogens of M. grisea, and that new MGR sequences did not occur following meiosis indicating that these sequences are stable in the genome. We conclude that restriction fragment polymorphism mapping with cloned MGR sequences as hybridization probes is an effective way to map genes in the rice blast fungus.

Stability of fat during irradiation and subsequent storage of irradiated buffalo meat.

Buffalo meat steaks were irradiated with gamma-rays in doses of 0,550 and 1100 krad and stored at 2 +/- 1 degree C. The changes in lipids extracted from the steaks were investigated. Peroxides and carbonyl compounds accumulated during irradiation and subsequent storage of the irradiated meat. Oxidation products were higher if irradiation was carried out with 1100 krad than with 550 krad. Soaking of the steaks in butylated hydroxy toluene (BHT) and sodium pyrophosphate before irradiation markedly reduced the amount of peroxides and carbonyl compounds formed during irradiation and storage. Treatment of meat muscle 800 V for 45 s reduced weeping but increased slightly the rate of autoxidation of lipids. The browning reaction was slow during cold storage of irradiated meat but increased upon storage of extracted lipids at room temperature.

Epidemiological study of sporotrichosis and histoplasmosis in captive Latin American wild mammals, São Paulo, Brazil.

Sporotrichosis and histoplasmosis are deep mycosis with a high incidence in human beings in Brazil. In domestic animals histoplasmosis has been described only in dogs, but the occurrence of sporotrichosis among domestic animals in Brazil has been described in dogs, cats, mules and asses. There is also a case of this disease reported in a chimpanzee (Pan troglodites). The purpose of this research was to perform an epidomiological study of these mycoses using delayed hypersensitivity tests (histoplasmin and sporotrichin) in Latin American wild mammals. This research was assayed using 96 healthy animals at Parque Zoológico de São Paulo, Brazil: Primates: 33 Cebus apella--weeping-capuchin and 16 Callithrix jacchus--marmoset; Procyonidae: 37 Nasua nasua--coatimundi and 10 Felidae (Panthera onca--jaguar; Felis pardalis--ocelot Felis wiedii--margay; Felis tigrina--wild cat). For intradermic tests, the following antigens were used: Sporothrix schenkii cell suspension (sporotrichin, histoplasmin-filtrate), Histoplasma capsulatum cell suspension (histoplasmin), and Histoplasma capsulatum (polysaccharide). The positivity to histoplasmin was 44.79% (Cebidae 15.15%; Callithricidae 6.25%; Procyonidae 86.49% and Felidae 50.00%, respectively). With respect to sporotrichin, 30.21% (Cebidae 6.06%, Callithricidae 0.0%; Procyonidae 64.86% and Felidae 30.00% respectively). The pattern of infection is similar to that shown by human beings and this may suggest that these animals could be involved in the epidemiologic chain of sporotrichosis and histoplasmosis, the second most prevalent human deep mycoses in Brazil. It is important to point out the absence of similar studies in Latin American wild animals.

Induction kinetics of delayed fluorescence of sun and shade leaves of Fagus sylvatica in the ms-range.

Induction kinetics of luminescence (= delayed chlorophyll fluorescence or delayed light emission) were measured with sun and shade leaves of a tall beech tree (Fagus sylvatica 'pendula', weeping beech). The kinetics detected in the ms-range are contrasted for the upper and the lower leaf side. The influence of the following parameters is demonstrated: time of dark-adaptation prior to the measurement, intensity of the excitation light and photoinhibitory treatment. The effects are discussed with respect to chlorophyll concentration, absorption of the excitation light, reabsorption of the luminescence and photosynthetic activity of the leaf tissue. It is shown that the luminescence signal and its kinetic are determined mainly by the properties of the mesophyll parenchyma facing the detector. Thus the more densely packed palisade parenchyma at the upper leaf side exhibits a lower luminescence and a slower kinetic than the spongy parenchyma at the lower leaf side, which is characterized by many aerial interspaces. Our study shows that luminescence kinetics can be applied to interpret the physiological state of a specific leaf tissue. They may serve as an indicator of disorders in the photosynthetic function.
