1. Vomiting and restlessness following ENT and eye surgery are undesirable, and may be related to the emetic and analgesic effects of any analgesic given to augment anaesthesia during surgery. 2. To rationalise the choice of analgesic for routine ENT surgery we examined the intraoperative, recovery and postoperative effects following the administration of either buprenorphine (3.0 to 4.5 micrograms kg-1), diclofenac (1 mg kg-1), fentanyl (1.5 to 2.0 micrograms kg-1), morphine (0.1 to 0.15 mg kg-1), nalbuphine (0.1 to 0.15 mg kg-1), pethidine (1.0 to 1.5 mg kg-1) or saline (as control) given with the induction of anaesthesia in 374 patients. A standardised anaesthetic technique with controlled ventilation using 0.6-0.8% isoflurane in nitrous oxide and oxygen was employed. The study population constituted 7 similar groups of patients. 3. Intraoperatively, their effects on heart rate and blood pressure, airway pressure and intraocular pressure, were similar. This implies, most surprisingly, that neither their analgesic nor their histamine releasing effects were clinically evident during surgery. By prolonging the time to extubation at the end of anaesthesia, only buprenorphine, fentanyl, morphine and pethidine provided evidence of intraoperative respiratory depression. 4. Postoperatively, buprenorphine was associated with severe respiratory depression, prolonged somnolence, profound analgesia and the highest emesis rate. Diclofenac exhibited no sedative, analgesic, analgesic sparing, emetic or antipyretic effects. Fentanyl provided no sedative or analgesic effects, but was mildly emetic. Morphine provided poor sedation and analgesia, delayed the requirement for re-medication and was highly emetic. Nalbuphine and pethidine produced sedation with analgesia during recovery, a prolonged time to re-medication and a mild emetic effect. None provided evidence, from analysis of postoperative re-medication times and analgesic consumption, of any pre-emptive analgesic effect. 5. We conclude that nalbuphine (mean dose 0.13 mg kg-1) and pethidine (mean dose 1.35 mg kg-1), given individually as a single i.v. bolus during induction of anaesthesia, are the most efficacious analgesics for routine in-patient ENT surgery.

A prospective study to compare 3 different types of nasal pack after septoplasty with or without a supplementary turbinectomy has been performed with respect to discomfort and complications caused by the packing and the short-term results evaluated 3 months after operation. Fingerstall packings gave less problems than either Merocel or hydrocortisone-terramycine gauze packs with ventilation tubes. They were easier to remove and were associated with less persistent secretion in the post-operative period. No definite advantage from the patient's point of view has been demonstrated by the use of tubes and nasal packing. An analysis of the nasal patency 3 months post-operatively by peak-flow index and acoustic rhinometry revealed no differences between groups.

The effectiveness of high-titre rubella immunoglobulin was tested on rubella-susceptible female juveniles or young adults after intranasal immunization with rubella strain RA 27/3, 20 ml of rubella immunoglobulin having been administered intramuscularly to 56 subjects at different times (1, 3 and 5 days) after the immunization. The effect was demonstrated by seroconversion and virus isolation from the throat. In the control subjects (26) the secroconversion was 96% and in 42% of subjects virus was demonstrated in the throat. Early administration of rubella immunoglobulin (up to three days after immunization) depressed the seroconversion rate to 55% and virus isolation rate to 17.5%. Later administration (five days after immunization) increased the conversion rate to 81%, the isolation rate to 31%. There were no serious side effects of the immunization and the injection of the immunoglobulin. The results indicate that on early administration of an adequate amount of high-titre rubella immunoglobulin a protective effect can be expected, although this favourable effect-obtained in the conditions of this study-cannot be unreservedly transposed to the situation in wild virus infections.

Equine rhinitis B virus (ERBV) has been given little attention by practitioners compared to other respiratory viruses, mainly because of the lack of diagnostic modalities and association with clinical disease. The objective of the study was to determine the frequency of detection of ERBV in nasal secretions from 6568 horses with acute onset of respiratory signs.. ERBV-positive qPCR results from nasal secretions submitted to a molecular diagnostic laboratory from 2013 to 2019 were reviewed.. A total of 333 ERBV qPCR-positive samples (5.1%) were detected with increasing yearly frequency since the introduction of the assay in 2013. In comparison, only three of 356 (0.8%) healthy horses tested qPCR-positive for ERBV. Median age for ERBV qPCR-positive horses was 3 years of age, and fever, coughing and nasal discharge were the most common signs reported. Further, co-infections with other respiratory pathogens were reported in 73 (21.9%) of ERBV qPCR-positive samples.. ERBV is a commonly detected respiratory virus from nasal secretions of young horses presenting with fever, nasal discharge and coughing.

The goals of this study were to evaluate whether touch can identify a warm nose as opposed to a cold nose, to examine the correlation between thermographically measured nose temperatures and rectal temperatures, and to calculate the accuracy of tactile assessment of nose temperature in detecting rectal hyperthermia and hypothermia in dogs. A total of 100 dogs presenting to an emergency room was prospectively enrolled. Tactile nose assessment was carried out on triage. Noses were subjectively categorized as warm, cold, or intermediate (neither warm nor cold). Thermographic nose temperatures were recorded using a thermal imaging camera. Tactile assessment categorized noses as warm, intermediate, or cold (. Les objectifs de cette étude étaient d’évaluer si le toucher peut identifier un nez chaud par opposition à un nez froid, d’examiner la corrélation entre les températures nasales mesurées thermographiquement et les températures rectales, et de calculer la précision de l’évaluation tactile de la température nasale dans la détection de l’hyperthermie et l’hypothermie rectale chez le chien. Un total de 100 chiens se présentant aux urgences a été enrôlé de manière prospective. Une évaluation tactile du nez a été réalisée lors du triage. Les nez ont été classés subjectivement comme chaud, froid ou intermédiaire (ni chaud ni froid). Les températures thermographiques du nez ont été enregistrées à l’aide d’une caméra thermique. L’évaluation tactile a classé les nez comme chauds, intermédiaires ou froids (

The characteristics and risk factors of respiratory syncytial virus (RSV) infection among children has not yet been fully understood. To address the characteristics of RSV-associated illness and risk factors of RSV infection among children under 5 years of age in Suzhou, China. From April 2011 to March 2014, we conducted a prospective surveillance among children in Suzhou, China. Nasal or throat swabs were collected from outpatients with influenza-like illness (ILI) and inpatients with severe acute respiratory infections (SARI). RSV was detected by reverse-transcriptase polymerase chain reaction and direct fluorescent antibody assay for children with ILI and SARI, respectively. Multivariable logistic-regression models were constructed to explore risk factors and symptoms of RSV infection. Of 3267 ILI and 1838 SARI children enrolled in the study, 192 (5.9%) and 287 (15.6%) tested positive for RSV, respectively. Among ILI patients, children with RSV infections visited clinics more often (P = 0.005) and had longer duration of fever (P = 0.032) than those without RSV infection. All RSV-positive children had an increased risk of having cough (OR = 2.9), rhinorrhea (OR = 1.6), breathing difficulty (OR = 3.4), wheezing (OR = 3.3), and irritability (OR = 2.7). Children aged <2 years, had history of prematurity (OR = 2.0) and recent respiratory infections (OR = 1.3) were more likely to get infected by RSV. Children with SARI had higher positive rate of RSV than those with ILI. Cough, rhinorrhea, and wheezing were the most common symptoms in RSV infection. Children aged <2 years, had history of prematurity and recent respiratory infections were the potential risk factors for RSV infection.

Infrared thermography (IRT) is used to screen febrile passengers at international airports, but it suffers from low sensitivity. This study explored the application of a combined visible and thermal image processing approach that uses a CMOS camera equipped with IRT to remotely sense multiple vital signs and screen patients with suspected infectious diseases.. An IRT system that produced visible and thermal images was used for image acquisition. The subjects' respiration rates were measured by monitoring temperature changes around the nasal areas on thermal images; facial skin temperatures were measured simultaneously. Facial blood circulation causes tiny color changes in visible facial images that enable the determination of the heart rate. A logistic regression discriminant function predicted the likelihood of infection within 10s, based on the measured vital signs. Sixteen patients with an influenza-like illness and 22 control subjects participated in a clinical test at a clinic in Fukushima, Japan.. The vital-sign-based IRT screening system had a sensitivity of 87.5% and a negative predictive value of 91.7%; these values are higher than those of conventional fever-based screening approaches.. Multiple vital-sign-based screening efficiently detected patients with suspected infectious diseases. It offers a promising alternative to conventional fever-based screening.

Influenza infections may result in different clinical presentations. This study aims to determine the clinical differences between circulating influenza strains in a young healthy adult population in the tropics.. A febrile respiratory illness (FRI) (fever ≥ 37.5°C with cough and/or sore throat) surveillance program was started in 4 large military camps in Singapore on May 2009. Personnel with FRI who visited the camp clinics from 11 May 2009 to 25 June 2010 were recruited. Nasal washes and interviewer-administered questionnaires on demographic information and clinical features were obtained from consenting participants. All personnel who tested positive for influenza were included in the study. Overall symptom load was quantified by counting the symptoms or signs, and differences between strains evaluated using linear models.. There were 434 (52.9%) pandemic H1N1-2009, 58 (7.1%) seasonal H3N2, 269 (32.8%) influenza B, and 10 (1.2%) seasonal H1N1 cases. Few seasonal influenza A (H1N1) infections were detected and were therefore excluded from analyses, together with undetermined influenza subtypes (44 (1.5%)), or more than 1 co-infecting subtype (6 (0.2%)). Pandemic H1N1-2009 cases had significantly fewer symptoms or signs (mean 7.2, 95%CI 6.9-7.4, difference 1.6, 95%CI 1.2-2.0, p < 0.001) than the other two subtypes (mean 8.7, 95%CI 8.5-9.0). There were no statistical differences between H3N2 and influenza B (p = 0.58). Those with nasal congestion, rash, eye symptoms, injected pharynx or fever were more likely to have H3N2; and those with sore throat, fever, injected pharynx or rhinorrhoea were more likely to have influenza B than H1N1-2009.. Influenza cases have different clinical presentations in the young adult population. Pandemic H1N1 influenza cases had fewer and milder clinical symptoms than seasonal influenza. As we only included febrile cases and had no information on the proportion of afebrile infections, further research is needed to confirm whether the relatively milder presentation of pandemic versus seasonal influenza infections applies to all infections or only febrile illnesses.

Several studies have compared nasal swabs to the more invasive nasopharyngeal aspirate (NPA) for detection of respiratory viruses. Mostly, the comparisons have been performed on immunocompetent children with upper respiratory tract symptoms. The results range from a relatively poor sensitivity for the swabs to an even higher sensitivity than for the NPA. We aimed to investigate the sensitivity of a flocked nasal swab (fNS) on immunocompromised adults with febrile neutropenia.. During 16 months, adults with a hematological disorder presenting with febrile neutropenia were enrolled in the study. Paired samples of the fNS and NPA were collected in the outer part of the nasal cavity and the nasopharynx, respectively. The samples were analyzed regarding a panel of 15 respiratory viruses by means of quantitative polymerase chain reaction. Furthermore, as an indirect measure of cell yield by either method, the copy number of the human beta actin gene was also determined. Cohen's kappa was calculated as a measure of agreement of the results obtained from either method. Wilcoxon signed-rank test was used for comparison of cell yield.. A total of 98 paired samples from a total of 89 patients were collected. Twenty of the pairs had virus detected in at least one of the specimens; 11 in both, 7 in NPA only, and 2 in fNS only. For the fNS, the overall sensitivity for any virus and for rhinovirus only was 65% and 78%, respectively. NPA was significantly superior to the fNS in collecting epithelial cells.. We found the overall sensitivity of 65% to be too low to replace NPA with this sampling technique in this patient category.

A 4.5-year-old, male castrated ferret was examined with a 27-day history of severe pruritus, generalized erythema and scaling. Skin scrapings and a trichogram were negative for mites and dermatophyte organisms. A fungal culture of hair samples was negative. The ferret was treated presumptively for scabies and secondary bacterial and yeast infection with selamectin, enrofloxacin, fluconazole, diphenhydramine and a miconazole-chlorhexidine shampoo. The ferret showed mild improvement in clinical signs over the subsequent 3 weeks, but was inappetent and required supportive feeding and subcutaneous fluids by the owner. The ferret was then examined on an emergency basis at the end of 3 weeks (53 days following initial signs of illness) for severe blood loss from a haematoma over the interscapular region, hypotension and shock. The owners elected euthanasia due to a poor prognosis and deteriorating condition. On post-mortem examination intraepithelial canine distemper viral inclusions were identified systemically, and abundant canine distemper virus antigen was identified with immunohistochemical staining. It is important to note the prolonged course of disease along with the absence of respiratory and neurological signs because this differs from the classic presentation of canine distemper virus infection in ferrets. Canine distemper virus should remain a clinical suspicion for ferrets with skin lesions that do not respond to appropriate therapy, even in animals that were previously vaccinated.

A nasal septal abscess is usually the result of an infected hematoma of the septum. A secondary septal abscess may be the result of infections extending from any of the neighbouring tissues. The necrosis of septal cartilage may lead to nasal deformities and severe impairment of nasal patency and growth.. Assess if the drainage of the abscess and the immediate reconstruction of the destroyed nasal septum in the acute phase is the best treatment to prevent short- and long-term effect on nasal and midface growth.. Three pediatric patients treated with drainage and immediate implantation of homologous bank cartilage prior to 1990 and four treated with mosaic plastic using small pieces of residual septal cartilage assembled with fibrin glue.. No complication were observed in the follow-up and any deformities in the long-term controls.. The drainage and immediate reconstruction of the nasal septum are the golden standard in the treatment of the septum infected haematoma.

To understand the demographic as well as clinical characteristics, and outcomes of patients with rhinocerebral mucormycosis in Taiwan, we retrospectively analyzed patients with this disease admitted to Chang Gung Memorial Hospital-Kaohsiung from 1988 through 2000. The 21 patients included 8 men (28%) and 13 women (62%). The median age was 60 years (range, 34-82 years). Twenty patients (95%) had underlying diabetes mellitus. The most common clinical feature at admission was ocular lesions, followed by headache, nostril lesions, and consciousness disturbance. Fifteen (94%) of 16 patients who received combined surgical debridement and therapy with amphotericin B survived, while only 1 (20%) of the 5 patients who received amphotericin B alone survived (p=0.004). The diagnosis of rhinocerebral mucormycosis was delayed in 4 patients (19%). Of the 16 patients who survived, 1 (6%) had delayed diagnosis, while of the 5 patients who died, 3 (60%) had delayed diagnoses (p=0.028). This series disclosed a higher proportion of patients with rhinocerebral mucormycosis in Taiwan had underlying diabetes mellitus, and ocular lesions were more frequent than nostril lesions at the time of admission. These results highlight the importance of the timely initiation of a combination of aggressive surgical debridement and treatment with amphotericin B in patients with rhinocerebral mucormycosis. Considering the high rate of delayed diagnosis, improved clinician's awareness of mucormycosis is extremely important and is in urgent need in Taiwan.

Two SPF kittens were experimentally infected via the intranasal route with a strain of calicivirus originally isolated from sick lion suffering from vesicular disease. Fever, 40.3 degrees C and 40.7 degrees C, and vesicular formation in tongue and snout were reproduced in both kittens. The infected virus was recovered from nasal, oral and rectal swabs. A longer duration of virus recovery was proved with oral swab samples taken from 1 to 10 and 12 days post infection. This suggests that tongue and oral tissues are the main tissues for virus multiplication.

Infectious complications associated with electroconvulsive therapy (ECT) are extremely unusual. When five of nine patients undergoing ECT at one facility on June 20, 1996 developed Staphylococcus aureus bloodstream infection (BSI), an investigation was initiated. A retrospective cohort study, a procedure review, and observational and microbiologic studies were performed. A case was defined as any patient who had ECT at Facility A from June 1, 1995 through June 20, 1996 and developed S. aureus BSI <30 days after ECT. The post-ECT S. aureus BSI rate was significantly greater on the epidemic day than the pre-epidemic period, (i.e., June 1, 1995 through June 19, 1996) (5 of 9 vs 0 of 54 patients, P < 0.001). All patients during the study period received propofol before ECT. Case patients were more likely than noncase patients to have higher maximum temperature after ECT (median 103.9 degrees F vs 100.0 degrees F, P < 0.03) and a greater time from preparation of intravenous medications to infusion (median 2.1 vs 1.1 h, P = 0.01). All case-patient S. aureus isolates were indistinguishable by pulsed field gel electrophoresis. Our investigation suggests that the ECT-associated S. aureus BSIs were associated with infection control breaks, which possibly led to the extrinsic contamination of propofol. Prevention of propofol-associated infectious complications requires aseptic preparation and use immediately before infusion.

Increased nasal air flow during exercise was examined as a possible heat loss avenue contributing to selective brain cooling in hyperthermic humans. On 2 separate days, eight subjects [mean (SE) age, 26.4 (1.2) years] exercised on a cycle ergometer in a warm room [28 (0.2) degrees C; 28 (5)% relative humidity] to induce a moderate level of hyperthermia. In one session the nostrils were physically dilatated [average dilatation 1.55 (0.17) times] and in the other they were not (control). Both sessions started with a 5-min resting period; then subjects pedaled at 60 W for 5 min, 100 W for 15 min, and 150 W for 20 min. During dilatation both tympanic temperature (Tty) and forehead skin blood flow, estimated by laser doppler velocimetry, were significantly lower than during the control exercise of 150 W. Rates of increase of Tty during the 100-W exercise were the same in both conditions; however, during the 150-W exercise with dilatated nostrils Tty increased at a rate significantly lower than during control [1.1 (0.3) degrees C.h-1 vs 1.5 (0.4) degrees C.h-1]. The change in the rate of increase of Tty between conditions was significantly correlated to the degree of nostril dilatation (r = -0.77, P = 0.02), suggesting that the lower Tty observed was due to nostril dilatation. Facial skin temperature was not significantly different between sessions. The results suggest that the nasal cavity may act as a heat exchanger in selective brain cooling of exercising humans.

Febrile intensive care unit (ICU) patients were evaluated prospectively for sinusitis. Of 598 admissions, 26 patients with transnasal cannulas, ICU stays over 48 hours, and occult fevers were identified. These 26 underwent physical examinations and sinus computed tomographic (CT) scans. Maxillary centeses and cultures were done in patients with CT abnormalities. Patients with positive scans had nasal tubes removed and received decongestants. Scans were abnormal in 19 (73%). All patients with major CT changes had positive maxillary taps. Most infections were polymicrobial; enteric bacilli were common. Fever resolved with nonoperative care in 18 (95%) patients; in only 1 patient was fever primarily from sinusitis. Sinus CT scans are often abnormal in ICU patients with occult fevers and transnasal cannulas. Pneumatic otoscopy can serve as a screening tool. Most patients respond to nonoperative management. Remote infections are often present. Although radiographic nosocomial ICU sinusitis is common, it is seldom the sole source of fever or the proximate cause of significant morbidity.

An influence of brain and trunk temperatures controlled independently of each other by means of artificial heat exchangers, on the intensity of natural selective brain cooling (SBC) was studied in 6 conscious goats. Intensity of SBC was markedly enhanced by increasing brain temperature. On the other hand, a rise of trunk temperature with the cerebral temperature clamped at 39 degrees C or 40 degrees C, reduced SBC intensity in spite of a simultaneous increase in the respiratory evaporative heat loss. When brain temperature was clamped at 41 degrees C, the magnitude of SBC was essentially independent of trunk temperature. These results suggest that during hyperthermia a competition exists between trunk and brain for cool nasal blood.

Previous work has shown that fever in influenza of ferrets occurs following release of endogenous pyrogen from virus-phagocyte interaction in the upper respiratory tract (URT), and suggested that the poor inflammatory response and correspondingly low fever elicited by A/Puerto Rico/8/34 (H1N1), compared with H3N2 reassortant clones of A/Puerto Rico/8/34-A/England/939/69, were related to its H1 and N1 surface antigens. Nasal virus levels, inflammatory and pyrexial responses produced in ferrets by clones 31 (H3N1) and 64b (H1N2) of the same reassortant system suggested a connection between the H1 antigen and low inflammatory response, but results were not conclusive. Unlike A/Puerto Rico/8/34, two recent H1N1 isolates, A/USSR/90/77 and A/Fiji/15899/83, produced a high inflammatory response yet low fever despite large amounts of virus in the URT, suggesting that either no connection exists between the acquisition of the H1 antigen and production of a low inflammatory response, or the H1 antigen of recent isolates, whilst antigenically related to that of A/Puerto Rico/8/34, is biologically different.

Fifty-four Merino crossbred sheep were inoculated with bluetongue virus serotype 20 (BTV-20) by the intravenous, subcutaneous and intradermal routes. BTV-20 was successfully transmitted by Culicoides (Avaritia) spp. No. 5 to two additional sheep. Clinical and pathological effects were studied. In the artificially infected sheep, clinical signs were observed after an incubation period of 6 to 10 days and consisted of pyrexia, oral and subcutaneous hyperaemia mild oedema of the ears, face and lips, and coronitis. The major internal pathological changes were petechial and ecchymotic haemorrhages in the tunica media of the pulmonary artery near its junction with the heart and mild haemorrhage and mild oedema in the intestines, coronet, lips, cheeks and ears. Viraemia was detected between day 2 and day 14 post inoculation. The two sheep infected by insect transmission were mildly affected and became viraemic between 16 and 19 days after transmission. No deaths occurred and under experimental conditions BTV-20 caused only mild disease in housed sheep. To date there has been no reported outbreak of natural bluetongue infection in Australia. Compared to other serotypes BTV-20 appears to be of low pathogenicity in sheep.

From July to December 1977, 217 patients underwent open heart surgery at this institution. From this group, 125 internal jugular venous lines (JVL) were collected, cultured and the organisms identified. Nose, throat, urine and sternotomy wounds were also cultured. Notable findings included a JVL contamination rate of 65%. The commonest infecting organism (90%) was Staphylococcus epidermidis (albus). This organism was also found in the nares in 74% of cases, but was not isolated from other sites. Postoperative pyrexia, but no morbidity or mortality, could be related to the JVL contamination. It was concluded that the source of the JVL contamination was the patient's neck skin, which itself is contaminated by the patients' noses.

After intranasal instillation into ferrets, the "swine" influenza virus A/New Jersey/8/76(Hsw1 N1) had a 50% minimal infectious dose similar to that of previously tested A/PR/8-A/England (H3 N2) recombinants virulent and attenuated for man. A/New Jersey produced only a mild upper respiratory tract infection. However, higher titres of virus were recovered from the lungs over a longer period than experienced previously with Asian and Hong Kong virus strains. There was a diphasic pyrexia the second and higher peaks of which correlated with peak titres of virus in lung macerates. These results suggest that A/New Jersey has a pneumotropic potential in ferrets and, if the animal model is valid, possible in man.

Daily observations were made on the excretion of African swine fever (ASF) virus by pigs infected intranasally or by contact. Two strains of virus having mean death times of approximately 3 and 6 days were used, the latter being recently isolated from a warthog.First excretion usually occurred by the nasopharyngeal route, as early as 1 or 2 days before the onset of fever in many cases. The titres of pharyngeal and nasal swabs rose rapidly to reach mean levels of about 10(4)-10(5) HAD 50 at 48-72 hr. following the onset of pyrexia. Virus in the secretions of the conjunctiva or lower urogenital tract appeared later and did not attain such high levels. Faecal and urinary excretion was of relatively little significance, except in slower infections caused by the recent warthog virus.These results are discussed in relation to the known failure of infected pigs to transmit the disease to stallmates during the first 12-24 hr. of pyrexia and also in relation to recent work on the pathogenesis of ASF in domestic swine.
