Lump in the throat.

The symptoms of repeatedly swallowing what the patient believes is a postnasal discharge, lump in the throat, and constantly having to clear the throat are commonly encountered in patients who do not show any evidence of sinusitis or organic lesions in the upper gastro-intestinal tract or larynx. It is suggested that incompetence of the lower oesophageal sphincter could lead to the creation of this situation by lowering the pH in the oesophagus and initiating inco-ordinate peristaltic movement. A trial of treatment of 54 patients, selected on a nonrandomized consecutive basis and presenting with the above symptoms, was undertaken, treatment being aimed at increasing the cholinergic activity of the oesophageal smooth muscle and neutralizing acidity. Metoclopramide (Maxolon, Primperan) was the cholinergic agent and polymethylsiloxane aluminium hydroxide (Asilone) was the antacid selected. Results based on symptomatic improvement showed that of 44 patients who reported for the follow-up examination, 35 (83%) had good symptomatic improvement, and 7 (16%) were unchanged. The action of metoclopramide is discussed and some of the literature reviewed. Favourable symptomatic improvement suggests that further trials using this substance, together with a placebo, on a cross-over randomized basis would be worth while. The 'lump in the throat' syndrome can be recognized by the symptom tetrad of: (i) lump in the throat; (ii) repetitive swallowing; (iii) clearing of the throat; and (iv) indigestion.

[Sore throat after tracheal intubation].

This study was performed to determine the incidence of sore throat 24 h after tracheal intubation in 1,268 patients ASA I or II, who had undergone elective surgery. A data form was completed. Nosing were age, sex, type of surgery, anaesthetic drug, muscle relaxant, number of intubation attempts, duration of intubation, and presence of sore throat. The incidence of sore throat was 15.06%. It was significantly higher in females than in males (19.29% vs 11.66%; P < 0.01). There was a significant difference between those patients who received fentanyl and those who received pethidine (P < 0.05). There was also a greater incidence after thyroid surgery (P < 0.01). There was no correlation between sore throat and variables such as age, muscle relaxant, narcotic drug, number of intubation attempts, or duration of intubation. Lidocaine jelly and the appropriate analgesic drug reduce the incidence of sore throat following tracheal intubation.

A randomized controlled trial of antibiotics on symptom resolution in patients presenting to their general practitioner with a sore throat.

BACKGROUND: Sore throat is a common symptom presented to general practitioners (GPs), and there remains controversy about the appropriate use of antibiotics. AIM: To compare, in a randomized controlled trial, the effectiveness of penicillin, cefixime and placebo on symptom resolution in patients presenting with a sore throat in general practice. METHOD: Twenty-two GPs in Avon recruited 154 patients, aged 16-60 years, presenting to their GP with a sore throat, and for whom the GP would normally prescribe an antibiotic. Patients were randomized to one of three groups: penicillin V 250 mg four times a day; cefixime 200 mg daily; and placebo. Each was prescribed for five days. The main outcome measures were a diary of symptom resolution over seven days and eradication of group A beta-haemolytic streptococcus (GABHS). RESULTS: Of the 103 (67%) patients who completed symptom diaries, 40 were allocated to receive penicillin, 29 cefixime and 34 placebo. In the analysis including all patients, symptom resolution was greater by day 3 in the cefixime group than in the placebo group. Penicillin did not improve symptom resolution by day 3 compared with placebo, and cefixime was not statistically significantly different from penicillin. There were significant differences in the proportion of patients using analgesia at day 3, with the proportion being lowest in the cefixime group. The results for the subgroup of patients without GABHS were similar to those for all patients; in particular, the only statistically significant difference was between cefixime and placebo. Although numbers were too small for statistical significance, among patients with GABHS the effects of penicillin and cefixime were similarly raised in relation to placebo. CONCLUSION: Compared with placebo, cefixime can improve the rate of resolution of symptoms in patients with a sore throat who are selected for antibiotic treatment by their GP. The unexpected finding that cefixime was of benefit compared with placebo for patients without GABHS suggests that bacteria other than GABHS may be important in the pathogenesis of sore throat.

[Propofol-air-oxygen anesthesia reduces the incidence of sore throat after laryngeal mask anesthesia].

We investigated the effects of the presence or absence of N2O in propofol anesthesia using a laryngeal mask on the incidence of postoperative sore throat. In the N2O-combined anesthesia group (n = 25), score 0 (no sore throat) was observed in 11 patients; score 1 (slight pain and discomfort that improved on the next day of operation) in 9; and score 2 (persistent pain on the next day) in 5. In the non-N2O-combined anesthesia group (n = 25), score 0 was observed in 21 patients, score 1 in 3; and score 2 in 1, showing a significantly lower incidence of sore throat and milder sore throat than in the N2O-combined anesthesia group. These results suggest that propofol anesthesia using a laryngeal mask not combined with N2O reduces the incidence of postoperative sore throat.

Clicking in the throat: cinematic fiction or surgical fact?

The complaint of a clicking in the throat when swallowing is uncommon but very discomforting and painful for those who experience it. It is such an unusual complaint that symptoms may be dismissed as psychogenic because a cause for the problem may not be readily apparent. We present a series of 11 cases in which all patients had an audible clicking or popping noise in the throat associated with neck and throat pain when swallowing or turning the neck. The most helpful diagnostic procedure was careful examination and palpation of the neck while the patient swallowed to localize the side and source of the clicking. Laryngeal computed tomographic (CT) scans helped in some cases to demonstrate thyroid-cartilage and/or vertebral body asymmetry. Each case was treated with surgery of the neck and larynx to trim the portion of the thyroid cartilage causing the clicking. In most cases the superior cornu of the thyroid cartilage projected posteriorly and medially. Surgery was successful in all cases to eliminate the symptoms. Though an uncommon complaint, our experience suggests that the clicking throat is a surgically treatable problem.

Infections of the ears, nose, and throat in children with primary immunodeficiencies.

Children who suffer from primary immunodeficiencies have long been thought to be subject to infections of the ears, nose, and throat due to unusual or resistant organisms. A retrospective chart review was undertaken at Children's Hospital of Pittsburgh from 1979 to 1989 to determine the types and frequency of infections of the ears, nose, and throat, and the bacteriologic findings from cultures of the sinuses, ears, and head and neck abscesses, when obtained. Seventy-five patients were identified with primary immunodeficiencies, and 80% suffered from infections of the ears, nose, and throat. Cultures obtained from 33% of the group showed the majority of the organisms commonly seen in ear and sinus infections. We conclude from this study that children with primary immunodeficiencies who require hospitalization frequently have an infection of the ears, nose, and throat, and that the infection is usually caused by community acquired bacteria. Empiric treatment may therefore be directed to common organisms causing these infections.

Management of sore throats in children: a cost-effectiveness analysis.

OBJECTIVE: To perform a cost-effectiveness analysis of treatment management strategies for children older than 3 years who present with signs or symptoms of pharyngitis. DESIGN: Decision model with 7 strategies, including neither testing for streptococcus nor treating with antibiotics; treating empirically with penicillin V; basing treatment on results of a throat culture (Culture); and basing treatment on results of enzyme immunoassay or optical immunoassay rapid tests, performed alone or in combination with throat cultures. In these 7 strategies, all tests are performed in a local reference laboratory. In a sensitivity analysis, we examined the cost-effectiveness of 4 strategies involving office-based testing. We obtained data on event probabilities and test characteristics from our hospital's clinical laboratory and the literature; costs for the analysis were based on resource use. RESULTS: At a baseline prevalence of 20.8% for streptococcal pharyngitis, the Culture strategy was the least expensive and most effective, with an average cost of $6.85 per patient. The outcome was sensitive to the prevalence of streptococcal pharyngitis, the rheumatic fever attack rate, the cost of the enzyme immunoassay test, and the cost of culturing and reporting culture results. The Culture strategy was also preferred if amoxicillin was substituted for oral penicillin. For office-based testing, Culture was the least costly strategy, but treatment based on results of the optical immunoassay test alone had an incremental cost-effectiveness ratio of $1.6 million per additional life saved. CONCLUSION: In a setting with adherent patients, children with sore throats should generally get throat cultures in lieu of rapid streptococcus antigen tests.

The diagnosis of group A, beta-hemolytic streptococcal pharyngitis in the office setting. Rapid latex test vs throat culture.

We compared a rapid latex agglutination test with cultures of throat specimens to diagnose group A beta-hemolytic streptococcal pharyngitis in an office setting. The throat cultures were interpreted by two pediatricians independently and evaluated by a reference laboratory. Five hundred seventy-two children participated in the study. The latex agglutination test had a sensitivity of 89.4% and a specificity of 85.7%. Cultures of throat specimens obtained in the office had a sensitivity of 91.9% and a specificity of 91.7% when interpreted by investigator 1, and a sensitivity of 90.0% and a specificity of 95.1% when interpreted by investigator 2. There was no statistically significant difference between the numbers of false-negative results generated by the two procedures. We conclude that although somewhat less specific, the latex test is as sensitive as cultures of throat specimens in the office setting.

Comparison of throat swabs and nasopharyngeal suction specimens in non-sputum-producing patients with cystic fibrosis.

Both throat swabs and nasopharyngeal suction (NPS) specimens are used for microbiological assessment in non-sputum-producing patients with cystic fibrosis (CF), but studies comparing their diagnostic yield are lacking. We, therefore, conducted a prospective study in young CF patients, in which both techniques were performed in random order. Forty-seven consecutive CF children aged 6 months to 10 years were studied during routine visits to the clinic. CF relevant pathogens were found in the majority of patients with no significant differences in the rate of positive cultures for Staphylococcus aureus, Haemophilus influenzae, or Pseudomonas aeruginosa. A statistically significant difference was observed in the rate of detection of other organisms with only 9/47 (19%) of throat swab specimens and 27/47 (57%) of NPS specimens being positive (P = 0.0004). This included 12 positive cultures for Streptococcus pneumoniae and 11 cultures that were positive for Moraxella catarrhalis, both of which are frequent colonizers of the upper airway. Therefore, the most common bacterial pathogens affecting the CF lung appear to be detected in similar frequency by throat swab as by nasopharyngeal suction. There is evidence that nasopharyngeal suction yields more specimens of Streptococcus pneumoniae and Moraxella catarrhalis, which may reflect upper airway colonization rather than lower airway infection. We conclude that nasopharyngeal suction is not routinely warranted as there is no benefit over throat swab in detection of CF pathogens in infants and young children with CF.

Emergency room management of patients with sore throats in a teaching hospital: influence of non-physician factors.

The care of 169 patients with sore throats was evaluated retrospectively to determine if the quality of medical care received in a teaching hospital's emergency room is associated with the degree of control managing physicians have over the medical care process. Diagnostic evaluation (temperature, throat and cervical node examination, and throat culture) was controlled by physicians and was judged adequate in 78% to 98% of the patients. Therapy, defined as appropriate antibiotics prescribed only for patients with positive throat cultures for group A beta-hemolytic streptococcus, was dependent on hospital support services, and the patients, as well, and was judged adequate for 62% of the patients; however, in only one of the 67 patients treated with antibiotics was the culture result known before treatment. The bacteriology laboratory processed the cultures slowly; no administrative mechanism existed to follow up patients. Thus, when medical care involved factors outside physicians' direct control, lower qualtiy care was given.

Diagnosis of streptococcal tonsillitis in general practice by clinical assessment and by office culture of throat swabs on Streptocult.

In a one-year study 274 general practitioners performed office cultures on Streptocult of throat swabs from 2,699 patients with acute pharyngotonsillitis in order to identify those with beta-haemolytic streptococci in the throat. The finding of group A beta-haemolytic streptococci by laboratory culture of corresponding throat swabs was used as a reference when determining the diagnostic value of either clinical assessment or Streptocult culture for the identification of patients with streptococcal pharyngotonsillitis. Based on 2,150 cases, sensitivity was 70% and 84%, respectively; specificity, 63%, respectively 77%; positive predictive value, 38%, respectively 53%; and negative predictive value, 87%, respectively 94%. Compared to the clinical assessment of the etiology, use of Streptocult resulted in the additional identification of 14% of the patients with group A streptococci and 13% of the patients without this organism present in the throat, as judged by laboratory culture. Overall, 78% of the patients were correctly diagnosed by the use of Streptocult, compared to 65% by clinical assessment. It is concluded that the use of Streptocult in general practice may be of substantial benefit in the identification of patients with group A streptococcal tonsillitis.

Comparison of nasopharyngeal aspirates and throat swab specimens in a polymerase chain reaction-based test for Mycoplasma pneumoniae.

Nasopharyngeal aspirates and throat swab specimens were compared in a polymerase chain reaction (PCR)-based test for Mycoplasma pneumoniae. The pathogen was detected in 50% and 45% of throat swab specimens and aspirates, respectively. However, in specimens negative for Mycoplasma pneumoniae by PCR, amplification inhibitors were detected in 0% and 36% of throat specimens and aspirates, respectively. Further investigations confirmed that no throat specimens, but one-quarter of aspirates, are likely to be rejected for containing inadequate respiratory material or excess amplification inhibitors. Because rejection of most of the unsuitable specimens is possible only after PCR, the use of aspirates is less cost-effective. This, and the reluctance to subject patients to aspiration, make the aspirate an inferior specimen for detection of Mycoplasma pneumoniae by PCR.

Clinical score card for diagnosis of group A streptococcal sore throat.

OBJECTIVE: Group A beta hemolytic streptococcus (GAS) sore throat primarily occurs among children in 5-15 years age group, and if not treated appropriately causes rheumatic fever/rheumatic heart disease (RF/RHD). Present study was aimed at validation of a clinical scoring system for diagnosis of GAS. METHODS: Five hundred and thirty six children in 5-15 years age group were enrolled by systematic random selection of households from a peri-urban slum of Chandigarh. They were visited fortnightly at their home for one year to record signs and symptoms of cough and cold. Throat swabs were collected in 918 episodes, of which 123 (13.4%) were GAS culture positive. RESULT: Significant association of GAS was found with pain in the throat, enlarged tonsils, pharyngeal erythema and tender cervical lymphadenopathy. According to the percentage positivity of GAS culture, weighted scores were assigned to age of the child, season of occurrence, fever, size of tonsil, pharyngeal erythema and exudate, lymphadenopathy and pain in throat. Combinations of various symptoms and signs gave sensitivity of 86-89% and specificity of 83-89% whereas clinical score of 15 or more had 91% sensitivity and 98% specificity for diagnosis of GAS pharyngitis. CONCLUSION: As the level of clinical acumen and prevalence of GAS may differ in different primary care settings of the country, the proposed scoring system should be validated and adapted to suit local conditions before establishing it in the primary prophylaxis strategy to prevention of RF/RHD.

Effect of clonidine premedication on postoperative sore throat and hoarseness after total intravenous anesthesia.

To determine the effect of oral clonidine premedication on postoperative sore throat and hoarseness, we evaluated the incidence and severity of each of these complications in patients who underwent elective surgery in the supine position. The subjects were 82 patients, American Society of Anesthiologists (ASA) status I-III, aged 15-82 years. They were premedicated with either 150 microg oral clonidine and 20 mg raftidine (clonidine group; n = 41) or with 20 mg raftidine only (control group; n = 41) 2 h before anesthesia induction. General anesthesia was maintained with propofol, ketamine, fentanyl, and vecuronium, with or without epidural anesthesia. Postoperative sore throat and hoarseness were evaluated immediately after surgery and on the day after surgery. The incidences of sore throat and hoarseness tended to be higher in the clonidine group than in the control group; however, the difference did not reach statistical significance. There were no significant differences in the severity of these symptoms between the two groups. In conclusion, oral premedication with 150 microg clonidine did not prevent postoperative sore throat or hoarseness, and may have exacerbated these symptoms.

Comparison of Visuwell enzyme immunoassay to culture for detection of group A Streptococcus in throat swab specimens.

A microwell enzyme immunoassay (Visuwell) for direct detection of Group A streptococcal antigen from throat swab specimens has been developed. It incorporates urease conjugated antibody as the detector and is easily interpreted by a yellow to purple color change. Throat specimens obtained on rayon-tipped swabs were transported moist in modified Stuarts medium and cultured before being tested in Visuwell (n = 585, prevalence 17.1%, sensitivity 88%, specificity 92.4%, predictive value positive 70.4%, predictive value negative 97.4%, and accuracy 91.6%). In instances of discrepancy between culture and Visuwell, throat swab extracts were tested in a latex agglutination test. In 21 of 37 instances of Visuwell-positive, culture-negative specimens, latex agglutination was positive. Throat specimens obtained using double rayon swabs and transported to the laboratory dry had one swab cultured and the other tested in Visuwell (n = 280, prevalence 20.4%, sensitivity 75.4%, specificity 88.3%, predictive value positive 62.3%, predictive value negative 93.4%, and accuracy 85.7%). When 1+ culture positive specimens were considered negative, a sensitivity of 97.6% was obtained. In 14 of 26 instances of Visuwell-positive, culture-negative specimens, latex agglutination was positive. Cross-reaction with organisms other than Group A Streptococcus found in the oropharynx was negligible in Visuwell. Limit of detection of Group A streptococcal antigen was equivalent for Visuwell and latex agglutination.

Pore throat size and connectivity determine bone and tissue ingrowth into porous implants: three-dimensional micro-CT based structural analyses of porous bioactive titanium implants.

A porous structure comprises pores and pore throats with a complex three-dimensional (3D) network structure, and many investigators have described the relationship between average pore size and the amount of bone ingrowth. However, the influence of network structure or pore throats for tissue ingrowth has rarely been discussed. Four types of bioactive porous titanium implants with different pore sizes and porosities (6mm in diameter and 15 mm long) were analyzed using specific algorithms for 3D analysis of interconnectivity based on a micro focus X-ray computed tomography system. In vivo histomorphometric analysis was performed using the very same implants implanted into the femoral condyles of male rabbits for 6 and 12 weeks. This matching study revealed that more poorly differentiated pores tended to have narrow pore throats, especially in their shorter routes to the outside. In addition, for assessment of the entire implant, we proposed new two indices that represent the degree of bone and tissue ingrowth into an implant by considering the effect of narrow pore throats. Data obtained suggest that this sort of novel analysis is useful for evaluating bone and tissue ingrowth into porous biomaterials.

Changes in the release of amino acid neurotransmitters in the brains of calves and sheep after head-only electrical stunning and throat cutting.

In calves aged two to five months, throat cutting resulted in an increase in the concentration of the amino acid neurotransmitters glutamate and aspartate in the brain. Electrical head-only stunning by itself also increased the concentrations of these two neurotransmitters. The levels induced by stunning resulted in a seizure state characterised by epileptiform-like activity in the electroencephalograph. Combing head-only stunning with throat cutting within 10 seconds of the stun had a synergistic effect upon glutamate and aspartate, increasing their concentration by a greater amount and more quickly than either procedure on its own. An irreversible loss of brain function also occurred more quickly than after throat cutting alone. The administration of glutamate and aspartate receptor antagonists before the throat cutting lengthened the time to the loss of brain function in a dose dependent manner. Similar changes were observed in sheep but they occurred much more quickly than in cattle.

[Topical methylprednisolone vs lidocaïne for the prevention of postoperative sore throat].

OBJECTIVE: We assessed the efficacy of topical methylprednisolone or lidocaine for prevention of postoperative sore throat. STUDY DESIGN: Randomised, prospective in single blind study. PATIENTS AND METHODS: Sixty patients ASA 1 or 2 undergoing tracheal intubation for dental surgery received before intubation either topical lidocaine 5% (15 puffs) or aerosolized methylprednisolone (80 mg). Postoperative pain was assessed by the patients using a VAS and a specific scoring system for sore throat, cough and hoarseness. Evaluations were performed immediately after emergence from anaesthesia, 1 h later, at time of the first postoperative drink, at time of the first postoperative meal and 24 h after surgery. RESULTS: Patients receiving methylprednisolone showed slightly better scores for sore throat and cough 1 h after surgery. CONCLUSION: Topical methylprednisolone may therefore be a useful adjuvant in the prevention of sore throat after intubation.
