About half of the aneurysm patients admitted to neurosurgical departments experience warning symptoms in the form of minor bleeding episodes days or even several months before a major haemorrhage occurs. Headache is the most common symptom of this warning leak, occurring in 9 out of 10 patients. The onset of headache is sudden and is unusual in severity and location, being unlike any headache the patient has otherwise experienced. It is frequently accompanied by transient nausea, vomiting, visual disturbances or meningism. Medical advice may be sought by the patient but all too often the diagnostic importance of a warning headache is missed. It is misinterpreted as attacks of migraine, tension headache, the 'flu, sinusitis, or a "sprained neck". A more vigilant attention to the presence of a warning headache probably offers the greatest opportunity for altering the otherwise serious natural history of aneurysmal subarachnoid haemorrhage. If a warning headache is suspected, lumbar puncture is the examination of choice, once CT scanning has ruled out an intracranial mass lesion.

In an open study, 70 in-patients and 23 out-patients aged between 1 and 14 years with sinusitis (n = 1), perforated otitis media (n = 4), pharyngotonsillitis (n = 25), tracheobronchitis (n = 30) or broncho-pneumonia (n = 33) were treated daily with a combination of 40 mg/kg amoxycillin and 10 mg/kg clavulanic acid in three equal doses for between 6 and 15 days. Purulent specimens were cultured when obtainable and pathogenic organisms identified were Staphylococcus aureus, beta-haemolytic streptococcal group A, Pseudomonas aeruginosa, Pseudococcus species and Klebsiella pneumoniae infections, of which 45.7% were beta-lactamase-producing and 54.3% were ampicillin-susceptible. After treatment, only one beta-lactamase-producing Streptococcus and one Staphylococcus infection persisted. Side-effects (vomiting, nausea, diarrhoea, maculopapular exanthema, rash) occurred in 16 patients and treatment was withdrawn in eight. It is concluded that the amoxycillin--clavulanic acid combination is a suitable first choice for the treatment of respiratory tract infections in children in whom the pathogenic organism may not have been established.

Erythromycin acistrate (EA)--a new ester of erythromycin--was compared with erythromycin base as enterocoated pellets in capsules (EB enterocapsules) and enterocoated tablets of erythromycin base (EB enterotablets) in the treatment of respiratory tract infections. The present double-blind, multicentre study, conducted in eight occupational health centres, included 474 patients; 236 treated with EA, 117 with EB enterocapsules and 121 with EB enterotablets. The diagnoses included tonsillitis, sinusitis, otitis media, bronchitis and pneumonia. The patients were examined on admission and at the end of the treatment. The dosage of EA was 400 mg tid and that of the two erythromycin base preparations 500 mg tid. The treatment was given for seven to 14 days. In the EA-group, 97% of patients were clinically cured by the end of the treatment, while the cure rates for EB enterocapsules and EB enterotablets were 95% and 94%, respectively. Gastrointestinal side effects were reported by 36% of the patients on EA, 54% on EB enterocapsules and 50% on EB enterotablets. Discontinuations due to adverse effects occurred in 8% in the EA, in 21% in the EB enterocapsule and in 12% in the EB enterotablet groups. All three preparations were thus equally effective, but EA caused statistically significantly less gastrointestinal side effects overall (P less than 0.01), especially nausea (P less than 0.01) and abdominal pain (P less than 0.05), than the two formulations containing erythromycin base. Also discontinuations due to side effects occurred statistically significantly less frequently in the EA-group.

The clinical effectiveness and safety of cefotiam (CTM) in infectious diseases in the field of otorhinolaryngology was evaluated from 30 patients (otitis media 18, pharyngeal infection 4, chronic paranasal sinusitis 1, esophagitis 1, acute bronchitis 1, others 4). Side effect (fever, nausea) was found in a 14 years old male patient. Skin test revealed positive in 1 patient. These cases were excepted from evaluating clinical effectiveness of CTM. In 28 patients, the overall ratio of clinical effectiveness was 60.7%. In patients of otitis media, the clinical effectiveness ratio was 41.2%, whereas the ratio was 75.0--100% in patients of other diseases. In particular, the clinical effect was fair or poor in patients to whom the drug was given only once a day. These results suggest that this chemotherapeutic drug should be administered at least twice a day, particularly to the patients of otitis media. The bacteriological response to CTM was evaluated from 53 strains, isolated from 28 patients before treatment. Eradication rate of bacteria was 60.4%. No abnormal laboratory findings, relating to the drug, were observed after treatment.

127 outpatients, 78 with acute purulent sinusitis and 49 with acute tonsillitis, were treated for 7 days with a benzylpyrimidine -sulphonamide combination. In this double-blind and randomized study 59 patients received co- tetroxazine (100 mg tetroxoprim and 250 mg sulphadiazine) b.i.d., whilst the reference substance, co-trimoxazole (160 mg trimethoprim and 800 mg sulphamethoxazole) was given to the remaining 68 patients b.i.d. The test criteria were the therapeutic efficacy and both subjective and objective tolerance. An improvement in clinical symptoms and signs occurred in both conditions under each therapeutic regimen. Clinical therapeutic success was rated very good or good in 96.6% treated with co- tetroxazine and in 97.1% of patients treated with co-trimoxazole. In the former group therapy failed in 1 patient with sinusitis and in 1 with acute tonsillitis . In 98.3% of patients treated with co- tetroxazine the tolerance was very good or good, whilst the respective figure for co-trimoxazole was only 91.2%. 6 patients suffered from side effects ( gastric spasm, gastralgia , nausea, vomiting, diarrhoea) which were so severe in 2 cases that treatment had to be prematurely terminated. The generally good tolerance to both preparations was confirmed by the results of the laboratory investigations.

It has been difficult to confirm that a given building is responsible for allergic symptomatology, exacerbation of asthma, or immunological dysfunction. In fact, in most studies, few objective immunological parameters have been studied and only rarely has there been any quantitation of IgE or secondary mediators. Furthermore, although many studies deal with rhinitis or respiratory tract irritation, there is a misconception that all such symptoms are allergic in nature, and studies attempting to prove that allergies are caused by buildings frequently neglect to prove that these are indeed true allergic responses. In addition, many of the symptoms that people attribute to sick building syndrome (SBS) or building-related illness, such as headaches, dizziness, fatigue, nausea, cough, and eye irritation, are subjective, and studies often fail to take into account other possible causes that may be inherent in the subjects, such as sinusitis, hyperventilation syndrome, or psychosomatic illness. Unfortunately, most clinical studies on SBS pay little attention to the preexisting conditions that a subject may have and discount the possibility that the inciting agent does not cause symptoms, but merely exacerbates a preexisting condition. Moreover, they offer no information about the nature of the mechanisms of action or pathophysiological relationships. Clearly, further studies are necessary to further explain the complexity of complaints that currently exist. Indeed, SBS might properly be paraphrased as "what is it?--if it is!"

A 15-year-old man was admitted because of diplopia and bilateral ptosis which occurred a few days after initial clinical signs, such as fever up, nausea, vomiting and headache. His pupils were anisocoric (Rt. phi 3.5 mm < Lt. phi 6.0 mm). In his left eye, light reflex was absent and its movements were limited in all directions. Brain MRI revealed the findings of paranasal sinusitis in bilateral ethmoidal and sphenoidal sinuses and swelling of bilateral cavernous sinus. Combination of intravenous antibiotic therapy and drainage improved his clinical symptoms and MRI findings. It was diagnosed as the inflammation originated in the sphenoid and ethmoid sinuses, which extended to the cavernous sinus and then involved III, IV, and VI cranial nerves. In conclusion, MRI was very useful to detect the cavernous sinusitis secondary to sphenoidal sinusitis.

The oral second generation cephalosporin cefprozil has a broad spectrum microbiologic profile, with good in vitro activity against respiratory pathogens; 90% or more of Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis isolates are susceptible to cefprozil. Clinical trials of cefprozil have consistently demonstrated good clinical success rates in upper and lower respiratory tract infections, including otitis media, sinusitis, pharyngitis/ tonsillitis and acute bacterial exacerbations of chronic bronchitis. Most recently cefprozil has demonstrated success in children with recurrent and persistent acute otitis media. Data from clinical trials including more than 4000 children and adults have shown that cefprozil is well-tolerated. The most common adverse events associated with cefprozil are gastrointestinal disturbances (i.e. diarrhea and nausea). In two patient satisfaction surveys (pediatric and adult), cefprozil was cited for having a low incidence of side effects and was rated by children as having a pleasing taste. These data indicate that cefprozil is a practical therapeutic choice for the treatment of upper and lower respiratory tract infections.

Cefprozil is a beta-lactamase-stable oral cephalosporin with an antimicrobial spectrum that includes gram-positive and gram-negative pathogens commonly associated with acute bacterial sinusitis, one of the most common upper respiratory tract infections among adults. We conducted a multicenter, open-label study to compare the efficacy and safety of cefprozil and amoxicillin/clavulanate in the treatment of adults with severe acute bacterial sinusitis diagnosed by clinical and radiographic criteria. A total of 278 patients entered the study, 140 (59 males, 81 females) in the cefprozil group and 138 (69 males, 69 females) in the amoxicillin/clavulanate group. Patients were randomized to 10 days of treatment with either cefprozil 500 mg BID or amoxicillin/clavulanate 500 mg/125 mg TID. Clinical severity was assessed at study entry, and patients were stratified based on symptom grade. Efficacy was evaluated using a 10-point questionnaire administered during, at the end of, and 2 weeks after completing therapy. At the end of treatment, 84.5% (71/84) of patients with severe sinusitis treated with cefprozil had a satisfactory clinical response, which was not significantly different from the 89.9% (80/89) of patients in the amoxicillin/clavulanate group who had a satisfactory clinical response. Two weeks after completing treatment, 80.8% (63/78) of cefprozil-treated patients and 81.0% (64/79) of amoxicillin/clavulanate-treated patients with severe sinusitis had a satisfactory response. Relapse was more common among amoxicillin/clavulanate patients (6/70; 8.6%) than among cefprozil patients (2/65; 3.1%), but the difference was not statistically significant. Significantly more amoxicillin/clavulanate-treated patients experienced adverse events compared with cefprozil-treated patients (P < 0.001), including diarrhea (P < 0.001), nausea (P < 0.042), and rash (P < 0.035). Three times as many amoxicillin/clavulanate patients discontinued treatment because of adverse events. Cefprozil demonstrated comparable clinical efficacy to amoxicillin/clavulanate in the treatment of adults with severe sinusitis; however, cefprozil was associated with a significantly lower incidence of diarrhea, nausea, and rash.

The safety profile of sparfloxacin, a newer fluoroquinolone antibiotic, was examined through an integrated analysis of safety data from 6 multicenter phase III trials. These consisted of 5 double-masked, randomized, comparative trials of sparfloxacin (a 400-mg oral loading dose followed by 200 mg/d for 10 days) versus standard therapies (erythromycin, cefaclor, ofloxacin, clarithromycin, and ciprofloxacin) and I open-label trial (noncomparative) in patients with: community-acquired pneumonia (2 trials); acute bacterial exacerbations of chronic bronchitis (1 trial); acute maxillary sinusitis (2 trials, one of which was the noncomparative trial); and complicated skin and skin-structure infections (1 trial). Overall, 401 (25.3%) of 1585 patients treated with sparfloxacin and 374 (28.1%) of 1331 receiving a comparator regimen experienced at least 1 adverse event considered to be related to the study medication. Photosensitivity reactions, usually of mild-to-moderate severity, were seen more frequently with sparfloxacin (7.4%) than with comparator agents (0.5%), whereas gastrointestinal reactions (diarrhea, nausea, dyspepsia, abdominal pain, vomiting, and flatulence), insomnia, and taste perversion were more common in patients taking comparator drugs (22.3% vs 12.1%, 4.3% vs 1.5%, and 2.9% vs 1.2%, respectively). Analysis of electrocardiographic findings showed that the mean change from baseline in QT interval corrected for heart rate (QTc) was significantly greater in sparfloxacin-treated patients (10 msec) than in patients given comparator drugs (3 msec), but no associated ventricular arrhythmias were detected. Adverse events led to discontinuation of study medication in 104 (6.6%) patients receiving sparfloxacin and 118 (8.9%) given com parator drugs. Sparfloxacin may be considered an appropriate choice for the treatment of certain community-acquired infections for patients who are not at risk for photosensitivity reactions or adverse events associated with prolongation of the QTc interval.
