The physician must be alert to the possibility of unsuspected sinusitis when evaluating a patient with chronic cough, sore throat, fever of unknown origin, supraglottitis, pneumonia, or headache. This article presents four cases in which atypical or asymptomatic sinusitis was discovered that could have caused significant or potentially life-threatening complications. In each case, the sinusitis was initially unsuspected. A complete nasal evaluation is warranted following decongestion of the nasal cavity when conditions are present. A screening sinus computed tomography scan may be indicated when sinusitis is strongly suspected even in the absence of typical clinical symptoms. Exact identification of the organism causing the infection may require sinus aspirate or tissue culture.

An epidemic of infection due to Mycoplasma pneumoniae occurred in Hong Kong in 1986-1988. One hundred and seventy-nine cases were identified at the Prince of Wales Hospital over this period. Clinically significant infection predominantly affected children under 12 years, with 32% of all infections occurring in children aged between 6 and 11 years, and 39% in children between 1 and 5 years. Ninety-seven percent of childhood infections were respiratory in nature, the other 4 presentations were neuropsychiatric. Adequate information was available on 36 of the 43 subjects over 12 years. One teenager presented with acute psychosis; all other cases (35) were respiratory. In these cases cough was universal, and fever was present in 34 (97%). A variety of non-specific symptoms (rigors/chills, malaise, headache, sore throat, sweating) were frequently noted. Sputum production was documented in 75% of cases, and was frequently purulent. Radiological consolidation was very common (95% of cases), but resolved fully after 4 weeks. Complications were rare and included acute pericarditis in 1 patient and haemolysis in another, and both patients recovered subsequently. Clinical recovery was otherwise rapid and complete in all other patients. Persisting dry cough was the only symptom documented at follow-up. Although infection due to M. pneumoniae in an ethnic Chinese population appears similar to that described in other populations, a higher incidence in younger children was recorded in this study.

From 1982 to 1991, we experienced 76 patients with Mycoplasma pneumoniae pneumonia which were confirmed by serologic tests. There were 32 (42%) male and 44 (58%) female patients. One patient had underlying disease of diabetes mellitus while the other patients were in good health. The age ranged from 9 months old to 72 years old. All the patients complained of fever and coughing; 63% had dry cough and 37% had sputum production. Upper respiratory tract complaints such as rhinorrhea, sore throat, or earache were noted in 57% of the patients. Fifty-five percent of the patients had GI symptoms of anorexia, nausea, vomiting, or diarrhea. Other complaints included myalgia/arthralgia (29%), headache (30%), and general malaise (32%). Dyspnea (17%) and chest pain (20%) were occasional complaints. Seventy-one percent of the patients had WBC counts < 10000/cu mm and 29% > 10000/cu mm. The mean value of C-reactive protein (CRP) was 53.1 micrograms/ml, while 16% of the patients had a CRP value above 100 micrograms/ml. Thirty-one percent of the patients were noted to have a transient elevation of serum transaminase. Four different patterns of infiltration were seen in chest radiographic manifestation: 1) peribronchial and perivascular interstitial infiltrates (18.4%), 2) nonhomogeneous patchy consolidations (22.4%), 3) homogeneous acinar consolidations (27.6%), and 4) mixed interstitial and alveolar infiltrates (27.6%). Interstitial infiltration was more commonly seen in pediatric than adult patients (46% vs 20%). Other features of the radiologic manifestation were as follows: unilateral lesions in 80% of patients, single lobe lesions in 77%, lower lobe predominant in 69%, pleural effusion in 7%, and radiographic deterioration in 10%. Mycoplasmal pneumonia should be considered in the differential diagnosis of community-acquired pneumonias.

We studied the painful symptoms associated with human immunodeficiency virus (HIV) infection and its treatment in a group of men enrolled in a prospective longitudinal study of HIV effects on the nervous system. The most common painful illnesses reported were HIV-related headaches, herpes simplex, painful peripheral neuropathy, back pain, herpes zoster, 3'-azido-3'-deoxythymidine (AZT)-induced headaches, throat pain, and arthralgia. Painful illnesses were reported at all stages of systemic disease but were more common in the later stages of disease and in subjects who progressed to a more advanced stage during the study period. There was an association between the frequency of multiple pains, increased disability on the Karnofsky scale, and higher depression scores, as measured by the Brief Symptom Inventory (BSI). We conclude that painful symptoms are important even in relatively healthy and independent HIV-infected men.

After a two week baseline, 209 asthmatic children (mean age 10 years, range 6-17) were randomly allocated to receive 4 mg nedocromil sodium (n = 110) or placebo (n = 99) four times daily for 12 weeks in addition to their current treatment. The children completed daily diary cards and visited the clinic at four week intervals. Statistically significant differences in favour of nedocromil sodium were seen for clinician assessment of asthma severity and diary card symptom scores, pulmonary function and inhaled beta 2 bronchodilator use. Total symptom score decreased by 50% from baseline in the nedocromil sodium group and by 9% in the placebo group during the final four weeks. Nedocromil sodium was considered very or moderately effective by 78% of children/parents (placebo 59%) and 73% of clinicians (placebo 50%). Nausea, headache and sleepiness, and dyspnoea led to withdrawal of one child from nedocromil sodium and placebo treatments, respectively. Reports of sore throat and headache were marginally greater with the nedocromil sodium treatment. It is concluded that nedocromil sodium was both effective and safe in the treatment of asthma in children.

We investigated the long-term health effects of HIV-1 infection in homosexual men not close to developing AIDS by comparing 916 HIV-1-seropositive (SP) men at least 1.67-3.67 years prior to a clinical AIDS diagnosis to 2,161 HIV-1-seronegative (SN) controls. The SP group reported a higher total of 12 distinct symptoms (fatigue, shortness of breath, night sweats, rash, cough, diarrhea, headache, thrush, skin discoloration, fever, weight loss, and sore throat/mouth) than did the SN group (p < 0.0001), corresponding to at least 5.6 more days/year of such symptoms. The SP group had lower body mass index (p < 0.0001) and lower hemoglobin (p < 0.0001). The SP group was more depressed, as measured by CES-D score (p = 0.047), before knowledge of one's serostatus was likely, and became even further depressed (p = 0.038 for increase in depression) after the HIV-1 serostatus test was accessible to high-risk groups. These associations remained unchanged in multivariate models, incorporating other covariates.

Poliomyelitis is an acute viral disease that attacks the brain and the ventral horn of the spinal cord. Damage to the lower motor neurons usually results in atrophy and weakness of muscle groups, perhaps paralysis and possibly deformity. A second type, bulbar poliomyelitis, infects the medulla oblongata and may result in dysfunction of the swallowing mechanism along with respiratory and circulatory distress. Minor forms of poliomyelitis result in fever, sore throat, headache, and upper body stiffness, but leave no significant atrophy or paralysis. The purpose of this paper is to review post-polio syndrome (PPS) as well as the effect of exercise on the symptoms and morphologic adaptations to PPS and where future research efforts should be directed. The most common features of PPS for over 350,000 afflicted survivors include general fatigue, weakness, and joint/muscle pain. The primary reasons for these symptoms include 1) destruction of the anterior horn cells by the polio virus, leaving fewer motor neurons to induce muscle contraction; 2) unaffected motor unit enlargement by reinnervation through terminal sprouting; and 3) defective transmission at the neuromuscular junction secondary to failure of terminal axonal sprout. Acute responses to resistive exercise suggest significant muscle strength decrements in the knee extensors compared with similar aged people without polio. However, limited training investigation indicates significant strength increases for the knee extensors following at least 6 wk of training. Acute aerobic responses also differ significantly from those observed in aged-matched control subjects. Chronic aerobic responses to limited training studies suggest significant elevations in maximal oxygen uptake.(ABSTRACT TRUNCATED AT 250 WORDS)

An outbreak of streptococcal pharyngitis due to a group A beta-hemolytic streptococcus has occurred in a French Army unit based in Djibouti during the month of september 1991. Out of 304 sick soldiers, 73% were seen by a physician in the initial 48 hours of the outbreak. All the patients showed a sore throat, associated with myalgia and rachialgia (85%), headache (26%) and digestive signs (24%). They were given a systematic antibiotic therapy by a penicillin or a macrolide, so no post-streptococcal complication was observed. From 23 throat swabs, 10 Streptococcus pyogenes strains were recovered with identical chimiotype, antibiotype and serotype (T:11, M non typable). Five serological assays were performed on 33 paired (early and 15 days later) samples of serum: ASLO (latex agglutination and microtitration), ASH, ASD and ASK. ASLO microtitration with ASD appear to be the most profitable association. The cost of such an outbreak is very heavy. More, the operational capacity of this unit was seriously compromised as long as 6 days. Measures to be applied are those used for the prevention of foodborne diseases, including medical surveillance of the cooking staff and strict observance of cool conservation of cooked meals and foods.

Two hundred and thirty-one patients were questioned the day following their cataract surgery to ascertain the incidence of postoperative morbidity. One hundred and nineteen patients received local anaesthesia (LA) and 112 received general anaesthesia (GA). There was a significant difference in the incidence of nausea (21% in GA group, 3% in LA group, p < 0.01), sore throat (41% GA group, 3% LA group, p < 0.01), and bruising of the eye (15% GA group, 39% LA group, p < 0.01). There was no significant difference in the incidence of vomiting, headache, double vision, the severity of postoperative pain, or the need for analgesia. The time before the patients drank and ate postoperatively was significantly shorter in the local anaesthetic group (1.3 h and 1.8 h LA group, 4.1 h and 6.7 h GA group respectively, p < 0.01).

1. The use of tear gas to control civil unrest is accepted practice by government authorities worldwide. It is rarely used in Hong Kong but during a recent riot at a Vietnamese detention centre large quantities were used and this was cause for some concern. 2. All patients presenting to the British Red Cross Clinic after the incident were seen by one of the authors. To establish if exposure to tear gas had serious effects on the health of the detainees, the case records of the 184 patients with symptoms consistent with CS exposure were reviewed 2 months later. 3. The most common complaints were burns (52%), cough (38%), headache (29%), shortness of breath (21%), chest pain (19%), sore throat (15%) and fever (13%). However, the only common findings on examination by a physician were burns (52%) and an inflamed throat (27%). All burns could be categorised as "minor' according to the American Burns Association classification and all were consistent with CS gas exposure. 4. Some patients complained of other symptoms that had not been previously reported in the literature, such as haemoptysis (8%) and haematemesis (4%), but these were only confirmed in one patient. 5. The majority of patients had recovered within 2 weeks of exposure although one asthmatic patient complained of shortness of breath lasting for 33 days and a sore throat lasting for 38 days after the incident. She had abnormally low peak expiratory flow readings, but had a clinical history of asthma. 6. No serious sequelae were encountered, but the incidence of burns in these patients was higher than would be expected from a review of the literature. However, very little data on the effects of tear gas in a riot situation has been published. There have been reports of high concentrations of CS gas causing reactive airways dysfunction but this was not seen in our group of patients.
