The RC/79 strain of the Aujeszky's disease virus was able to induce reproductive failure of pregnant gilts intranasally inoculated at different gestation periods. Four gilts 40-46 days pregnant (group A) and 6 gilts 70-73 days pregnant (group B) were instilled with 0.2 ml x 10(5) tissue culture infectious dose 50 (TCID50/0.2 ml) of the RC/79 strain into each nostril. Two gilts 70-73 days pregnant (group C) were used as non exposed controls. The three groups were kept in separated boxes and they were observed for clinical signs of infections and samples were collected for determination of viral shedding every day. Viral isolation was attempted in Vero cells (figure 1). From the 2nd to 7th day after inoculation, groups A and B showed fever anorexia, sneezing, coughing and depression; and viral isolation from nasal swabs was possible in 7 gilts at days 4 to 11, 9 gilts developed neutralizing antibodies. The virus caused fetal reabsorption in swine during the first period of pregnancy (group A), while infection during late pregnancy resulted in still birth or normal pigs and one mummification (group B). The entire a live litter was composed of no more than 8 suckling pigs in both groups. At necropsy virus from turbinates, ovary , placenta, spleen and lung could be isolated only from 3 gilts (group B, table 1). In 5 of 35 stillbirth and alive fetuses virus could be isolated from spleen (100%), lung (80%), liver (60%) and brain (40%) indicating that the virus has the ability to cross the placental barrier thus producing lesions in porcine fetuses and causing reproductive failure in sows (table 2). Tissue specimens from these 35 fetuses were fixed in 10% formalin, included in paraffin sectioned and stained with hematoxylin and eosin. In 13 fetuses microscopic lesions i.e. necrotic foci were found in lung (60%), liver (40%) and spleen (20%), these alterations were coincident with gross lesions in most of them. Inclusion bodies were absent. The gilts organs did not present gross lesions.

B6C3F1 mice were exposed to n-hexane 6 h/day, 5 days/week for 13 weeks at concentrations of 0, 500, 1000, 4000, and 10,000 ppm and at 1000 ppm 22 h/day, 5 days/week for 13 weeks (1000C group). Toxicological endpoints assessed included clinical signs, body and organ weight changes, gross and histopathology, neuropathology, and a battery of neurobehavioral tests. All mice survived the treatment. Exposure-related effects of n-hexane included sneezing at 10,000 ppm and body weight gain depression at 1000C and 10,000 ppm. Histopathologic changes included mild inflammatory, erosive and regenerative lesions in the olfactory and respiratory epithelium of the nasal cavity at 1000C, 4000, and 10,000 ppm. The only neurobehavioral parameter affected was a decrease in locomotor activity in female mice at 1000C and 10,000 ppm. In teased fiber preparations of tibial nerve, paranodal axonal swellings were observed at 1000C or at 10,000 ppm, but not in the control groups. The severity of the peripheral nerve lesion was mild. These studies show that n-hexane has minimal toxicity to the nervous system and respiratory system of mice.

An acute upper respiratory disease was observed in two broad-breasted white (BBW) turkey primary breeder flocks. Associated clinical signs included sneezing, depression, and a deep dry cough originating from large conducting airways. Morbidity reached approximately 15-20% of the hens in an affected house. None of the turkeys died, and total feed consumption was not affected. A minimal effect upon egg production was noticed. Sera from an acutely affected flock exhibited a marked rise in titer to Bordetella avium compared with preinfection sera samples. In Case 1, B. avium was isolated in pure culture from affected birds. In Case 2, B. avium was diagnosed by serological results and clinical signs; bacteriological examination was not attempted. The findings presented here are consistent with an acute clinical outbreak of B. avium-induced turkey rhinotracheitis (turkey coryza) in BBW turkey breeder hens.

A recently synthesized, non-halogenated steroid, budesonide, with high local anti-inflammatory properties, but with low systemic effect, was tested as a nasal spray in the treatment of patients with perennial rhinitis. Used in a dose of 200 micrograms and 400 micrograms budesonide per day in a double-blind cross-over study in 36 patients it was found to have an excellent and dose-dependent effect on nasal blockage and discharge as well as on sneezing bouts. Budesonide caused a considerable decrease in the nasal symptoms in 21 patients with demonstrable cutaneous and RAST allergy, as well as in a group of 15 patients without. The same alleviation of symptoms was noted in 22 patients with nasal eosinophilia but not in a group of 14 patients without. To determine possible adverse reactions during long term treatment, 15 patients with perennial rhinitis used budesonide as a nasal spray for more than two years. No adverse reactions serious enough to discontinue the treatment were noted in any of the patients. Haematologic parameters as well as adrenal gland function were monitored throughout the first 1.5 years. No depression was noted. Biopsy specimens of the nasal mucosae did not show any significant evidence of increased metaplasia.

Biological hypersensitivity is the fundamental feature of atopy, and patients suffering from this syndrome are characterized by their ability to produce high levels of IgE in response to low amounts of antigen. This hypersensitivity results in a range of acute and chronic diseases, such as asthma, rhinitis, allergic conjunctivitis and atopic dermatitis. In addition to their biological effects, these diseases may have psychological consequences in terms of stress, anxiety or depression. However, atopic patients, far from displaying a typical depressive psychological profile, are characterized by their increased emotional sensitivity. Atopic individuals alert us to the presence of allergens but perhaps they also indicate something about our way of life. Are the symptoms displayed by allergic patients, their wheezing, sneezing or itching skin, more than a simple biological response?

The upper airway is a vital part of the respiratory tract. Although the upper airway serves several functions, protection of the airway and preservation of airway patency are the most essential functions subserved by upper airway reflexes. Various types of nerve endings have been identified in and under the epithelium of the upper airway, and afferent nerve endings are the natural starting of all reflex activity. The upper airway reflexes consist of many different types of reflex responses such as sneezing, apnea, swallowing, laryngeal closure, coughing, expiration reflex, and negative pressure reflex. Although the activation of upper airway reflexes does not necessarily occur at one particular site of the respiratory tract, individual reflex response is usually considered to be highly specific for the particular respiratory site which has been affected. The upper airway reflexes are modified by many factors such as sleep, anesthesia, and background chemical ventilatory drive. Both depression and exaggeration of upper airway reflexes cause clinical problems. Depression of upper airway reflexes enhances the chance of pulmonary aspiration and compromises the maintenance of the airway, whereas exaggeration of airway reflexes such as laryngospasm and prolonged paroxysm of cough can be harmful and dangerous. In this review, various aspects of upper airway reflexes are discussed focusing on the functions of upper airway reflexes in humans and some pathophysiological problems related to clinical medicine.

Urinary incontinence in the elderly is a significant health problem fraught with isolation, depression, and an increased risk of institutionalization and medical complications. Stress urinary incontinence (SUI), the complaint of involuntary loss of urine during effort or exertion or during sneezing or coughing, is the most common type of urinary incontinence. SUI can seriously degrade the quality of life for many active seniors, and has become an economic challenge for society. With the rapid increase in the active elderly worldwide, SUI is becoming a significant global problem. However, since only a fraction of women with SUI have consulted a physician, the clinical extent and public health impact of SUI are probably underestimated. The mounting social, medical, and economic problem of SUI in active elderly women as a rapidly growing segment of the population worldwide is reviewed. We evaluate the age-related changes of the lower urinary tract, examine risk factors, and suggest different treatment options shown to be effective in reducing SUI in this population.

Urinary leakage is a hygienic and social problem, that concerns women both in reproductive and perimenopausal age. It leads to a life deterioration, depression, and social isolation. Urinary stress incontinence (USI) is one of the most common-type of urine leakage. Characteristic symptom of this disorder there is involuntary leakage of urine during increased intra-abdominal pressure (cough, laugh, sneezing or physical work). There are many various predictive factors of urinary stress incontinence in a large number of publications. One of them, the most important, seems to be a gravidity and labor. 40-82% pregnant women complain of urinary leakage. The main aim of investigation was to determine obstetrical and gynaecological predictive factors of urinary stress incontinence. 53 women with diagnosed USI and qualified to TVT procedure have to fill in questionnaire with row questions about their obstetrical and gynaecological history. Our investigation revealed that significant influence on appearance of USI exert number of spontaneous labors, birth weight >3500 g, lack of substitute hormonal therapy during menopause and hard physical work in the past.

Sensory neurons in the airways are finely tuned to respond to reactive chemicals threatening airway function and integrity. Nasal trigeminal nerve endings are particularly sensitive to oxidants formed in polluted air and during oxidative stress as well as to chlorine, which is frequently released in industrial and domestic accidents. Oxidant activation of airway neurons induces respiratory depression, nasal obstruction, sneezing, cough, and pain. While normally protective, chemosensory airway reflexes can provoke severe complications in patients affected by inflammatory airway conditions like rhinitis and asthma. Here, we showed that both hypochlorite, the oxidizing mediator of chlorine, and hydrogen peroxide, a reactive oxygen species, activated Ca(2+) influx and membrane currents in an oxidant-sensitive subpopulation of chemosensory neurons. These responses were absent in neurons from mice lacking TRPA1, an ion channel of the transient receptor potential (TRP) gene family. TRPA1 channels were strongly activated by hypochlorite and hydrogen peroxide in primary sensory neurons and heterologous cells. In tests of respiratory function, Trpa1(-/-) mice displayed profound deficiencies in hypochlorite- and hydrogen peroxide-induced respiratory depression as well as decreased oxidant-induced pain behavior. Our results indicate that TRPA1 is an oxidant sensor in sensory neurons, initiating neuronal excitation and subsequent physiological responses in vitro and in vivo.

Groups of 3-day-oId red-legged partridges were infected intranasally either with the S6 strain of M. gallisepticum or with an M. imitans strain from a partridge with sinusitis. Starting 6-8 days post-infection (p.i.) birds in both groups developed signs of depression, nasal exudation, tracheal rales, sneezing, gasping, head shaking, watery eyes and eye scratching. The most outstanding feature was bilateral swelling of the infraorbital sinuses. Morbidity reached 100% in the M. gallisepticum infection and 80% in the M. imitans infection and mean clinical scores in the former were significantly greater than those of the latter group on days 11 and 14 p.i. There was also slower recovery in the M. gallisepticum infection. Necropsies at weekly intervals for 5 weeks revealed nasal and sinus exudate in both groups but tracheal exudate and cloudy airsacs were seen only in M. gallisepticum infection. M. gallisepticum was isolated from both upper and lower respiratory tract throughout the experiment while M. imitans was recovered less frequently from the upper respiratory tract and from the lungs and air sacs only at 7 days p.i. The numbers of isolations from eyes, tracheas, lungs and thoracic air sacs of the M. gallisepticum group were significantly greater than those from the M. imitans group. Seroconversion occurred in both groups using homologous antigen.
