The efficacy and tolerance of the new oral cephalosporin cefaclor was tested in 61 patients treated for a variety of moderate to severe ENT infections which were not expected to undergo a spontaneous remission without antibacterial therapy. The most frequently isolated pathogens were streptococci and Staphylococcus aureus. The dosage consisted of 500 mg cefaclor three times daily, and the treatment lasted between 4 and 43 days (average 14 days). In 35 cases, some of whom had already been treated unsuccussfully with another antibiotic, the results were very good. In 22 patients locally applied medicaments or surgery contributed to the good result. In four patients an unequivocal evaluation was not possible or therapy was not successful. The frequently noted rapid response to treatment with cefaclor was impressive. No relapses were recorded. In pharmacokinetic studies a cefaclor concentration of 2.8 mcg/g was obtained in the tonsils 90 minutes after oral administration of 1000 mg. Clinical examinations in 61 patients and a complete range of laboratory tests in 47 patients did not reveal any case of allergic reaction. One patient only complained of nausea and diarrhoea. In two patients temporary low grade thrombopenia and thrombocytosis respectively were observed. In several patients a slight transitory rise in transaminases was seen. Cefaclor thus proved to be an effective and well-tolerated antibiotic. Its indications in the treatment of ENT infections are discussed.

A prospective, randomized trial comparing monotherapy with high-dose ciprofloxacin versus a standard combination regimen of azlocillin and netilmicin in the empirical treatment of febrile episodes in neutropenic patients was performed. One hundred and forty-six patient episodes were randomized, but ten (seven ciprofloxacin and three azlocillin/netilmicin) were considered unevaluable for efficacy, and three episodes were withdrawn due to incorrect randomization or non-neutropenia. Of the remaining 133 episodes, infections resolved without modification of therapy in 25/66 (38%) versus 28/67 (42%) of ciprofloxacin and azlocillin/netilmicin treated groups respectively (P = 0.72). Considering all randomized episodes, therapy was modified in 46/73 (63%) episodes with ciprofloxacin and 39/70 (56%) with azlocillin/netilmicin (P = 0.40). Of 73 patient episodes randomized to ciprofloxacin, 25 (34%) received oral follow-on therapy after a median of three days of intravenous therapy. Infections were microbiologically documented in 31/73 (42%) ciprofloxacin and 32/70 (46%) azlocillin/netilmicin, of which 8/27 (30%) and 14/31 (45%) of evaluable episodes resolved without modification of therapy respectively (P = 0.28). Gram-positive organisms accounted for 78% of all organisms cultured with 36% coagulase-negative staphylococci. Bacteriological eradication was recorded in 18/24 (75%) and 26/29 (90%) evaluable patient episodes treated with ciprofloxacin and azlocillin/netilmicin respectively (P = 0.27). Superinfections were seen in 14% of episodes in both groups, and subsequent infections in 12% ciprofloxacin and 14% azlocillin/netilmicin treated patients. Two patients (one ciprofloxacin and one azlocillin/netilmicin) died within 48 h of randomization, and a further 13 patients (four ciprofloxacin and nine azlocillin/netilmicin) died before resolution of neutropenia. Adverse events were recorded in 9% and 15% of ciprofloxacin and azlocillin/netilmicin treated patients respectively, with skin rash (five ciprofloxacin and four azlocillin/netilmicin), nephrotoxicity (two azlocillin/netilmicin), abnormal liver function tests (two azlocillin/netilmicin), ototoxicity (one azlocillin/netilmicin) and nausea (one ciprofloxacin) being the major events recorded. It was concluded that monotherapy with ciprofloxacin at this dosage is a safe alternative to combination therapy with azlocillin/netilmicin, and has the advantages of twice daily administration, iv and oral presentations, no cross allergy in beta-lactam-hypersensitive patients, and no nephro- or oto-toxicity.

Ten-day, double-blind, randomized, parallel treatment regimens of loracarbef (200 mg capsule twice daily or 15 mg/kg/day oral suspension in two divided doses up to a maximum of 375 mg/day; n = 169) and penicillin V (250 mg capsule four times daily or 20 mg/kg/day suspension in four divided doses up to a maximum of 500 mg/day; n = 175) were compared in the treatment of group A beta-haemolytic streptococcal (GABHS) pharyngitis and tonsillitis. Post-therapy clinical responses were similar for evaluable patients in both treatment groups: 97.4% of the loracarbef group (101/115 patients cured and 11/115 improved) and 96.0% of the penicillin group (101/124 patients cured and 18/124 improved). A statistically significant difference in the pathogen elimination rate was noted between treatment groups: post-therapy throat cultures were negative for GABHS in 94.8% (109/115) of loracarbef-treated patients compared with 87.1% (108/124) of penicillin-treated patients (p = 0.040). Loracarbef and penicillin V were comparable in terms of safety. Headache and nausea/vomiting were the most common events reported during therapy (nausea/vomiting were slightly less common in the loracarbef group). Three patients in each group were discontinued from the study due to drug-related adverse events; one due to rash in the loracarbef group and one due to rash and one due to vomiting in the penicillin group. These data support the conclusion that loracarbef twice daily is more effective in eradicating GABHS than penicillin V four times daily, and the two drugs are comparable in safety and clinical efficacy in the treatment of GABHS pharyngitis and tonsillitis.

An outbreak of severe haemorrhagic illness began in the municipality of Guanarito, Portuguesa State, Venezuela, in September, 1989. Subsequent detailed study of 15 cases confirmed the presence of a new viral disease, designated Venezuelan haemorrhagic fever. Characteristic features are fever, toxicity, headache, arthralgia, diarrhoea, conjunctivitis, pharyngitis, leucopenia, thrombocytopenia, and haemorrhagic manifestations. Other features include facial oedema, cervical lymphadenopathy, nausea/vomiting, cough, chest or abdominal pain, and convulsions. The patients ranged in age from 6 to 54 years; all were residents of rural areas in central Venezuela, and 9 died. Infection with Guanarito virus, a newly recognised arenavirus, was shown by direct culture or by serological confirmation in all cases. Epidemiological studies suggest that the disease is endemic in some rural areas of central Venezuela and that it is rodent-borne. Venezuelan haemorrhagic fever has many similarities to Lassa fever and to the arenavirus haemorrhagic fevers that occur in Argentina and Bolivia.

The results of an open randomised trial comparing the efficacy of parenteral and oral ofloxacin with that of amoxycillin clavulanate are reported. Of 121 patients enrolled, 92 were clinically evaluable, of whom 59 were treated with ofloxacin and 33 with amoxycillin clavulanate. In the ofloxacin group all patients improved clinically, while in the amoxycillin clavulanate group 94% improved and 6% were clinical failures. In the ofloxacin group 95% showed satisfactory bacteriological response, while in the amoxicillin clavulanate group the bacteriological response was judged satisfactory in 82% of the patients. Seven percent of the patients had mild side effects (headache, nausea, vomiting and skin rashes). All of these side effects disappeared after treatment. We conclude that ofloxacin is a safe and effective drug in oral and parenteral forms for the treatment of lower respiratory tract infections.

The choice of therapy in urinary tract infections depends on the infection site, complications, previous history, and recrudescence. Acute uncomplicated urinary tract infections which do not respond to general measures as increased fluid intake will be cured with antibiotics for 3 days. If the compliance of the patient is sufficient a single shot therapy may be applied. Infections of the upper urinary tract with typical signs such as fever, nausea and increase of the so-called acute phase proteins have to be treated with antibiotics for 7 to 14 days. When treating the first episode of urinary tract infection the choice of antibiotics is unimportant. Trimethoprim and quinolones are standard. In recurrent infections urine cultures and susceptibility testing are mandatory. Patients with recurrent urinary tract infections should receive a long-term suppressive therapy with low-dose trimethoprim or a quinolone. Patients with urinary catheters must not receive any long-term therapy.

We analysed two of our own and 21 patients described in the literature with listeria brainstem encephalitis. The disease was characterised by a prodromal state with fever, nausea and headache followed by severe brainstem dysfunction with multiple cranial nerve palsies, ataxia, respiratory insufficiency and coma. The diagnosis was established by isolation of Listeria monocytogenes from CSF and/or serum. Serological tests are without diagnostic evidence. Cerebrospinal fluid examination may not initially point to a bacterial infection. Computed tomography and magnetic resonance imaging technique might supply evidence of brainstem involvement and contribute to an early diagnosis. There is a high percentage of lethal outcome without early antibiotic therapy.

While evolution by natural selection has long been a foundation for biomedical science, it has recently gained new power to explain many aspects of disease. This progress results largely from the disciplined application of what has been called the adaptations program. We show that this increasingly significant research paradigm can predict otherwise unsuspected facets of human biology, and that it provides new insights into the causes of medical disorders, such as those discussed below: 1. Infection. Signs and symptoms of the host-parasite contest can be categorized according to whether they represent adaptations or costs for host or parasite. Some host adaptations may have contributed to fitness in the Stone Age but are obsolete today. Others, such as fever and iron sequestration, have been incorrectly considered harmful. Pathogens, with their large populations and many generations in a single host, can evolve very rapidly. Acquisition of resistance to antibiotics is one example. Another is the recently demonstrated tendency to change virulence levels in predictable ways in response to changed conditions imposed incidentally by human activities. 2. Injuries and toxins. Mechanical injuries or stressful wear and tear are conceptually simpler than infectious diseases because they are not contests between conflicting interests. Plant-herbivore contests may often underlie chemical injury from the defensive secondary compounds of plant tissues. Nausea in pregnancy, and allergy, may be adaptations against such toxins. 3. Genetic factors. Common genetic diseases often result from genes maintained by other beneficial effects in historically normal environments. The diseases of aging are especially likely to be associated with early benefits. 4. Abnormal environments. Human biology is designed for Stone Age conditions. Modern environments may cause many diseases-for example, deficiency syndromes such as scurvy and rickets, the effects of excess consumption of normally scarce nutrients such as fat and salt, developmental diseases such as myopia, and psychological reactions to novel environments. The substantial benefits of evolutionary studies of disease will be realized only if they become central to medical curricula, an advance that may at first require the establishment of one or more research centers dedicated to the further development of Darwinian medicine.

In a prospective, open clinical study, 50 urological patients with acute pyelonephritis were treated with the oral cephalosporin cefixime. The medication (2 x 200 mg/day) was given for seven to ten days. Clinical, bacteriological as well as hematological examinations were carried out prior to, during and immediately after therapy. A late check-up was performed five to nine days after the end of therapy. 46 of the 50 cases were evaluable for efficacy, and all 50 patients were included in safety evaluation. The most frequent pathogens isolated prior to therapy were Escherichia coli (34 times), Proteus mirabilis (six times), Klebsiella pneumoniae (twice) and coagulase-negative staphylococci (twice). Immediately after the end of therapy the pathogens were eradicated in 44 (97.5%) patients. At the late check-up the urine was sterile in 29 (63%) patients. A relapse was observed in 11 patients, a reinfection in four and the initially isolated pathogens had persisted in two. Immediately after the end of therapy 44 (95.7%) patients were clinically cured and two patients had improved. At the late check-up 41 patients were classified as clinically cured, three showed improvement, and two improvement with relapse. Adverse reactions (one case nausea and exanthem, and one case of meteorism) occurred in two patients. No changes in the blood counts or in the liver and kidney functions were observed. In the study described here cefixime proved to be an effective and well tolerated antibiotic for the treatment of upper urinary tract infections; it is of particular interest that 16 of the 50 patients presented with underlying disease favoring infection.

In a randomized, double blind, placebo-controlled study 36 patients aged 16-77 years who had been carriers of nontyphi Salmonella species for 10-21 weeks were given the combination pivampicillin/pivmecillinam or placebo for four weeks in order to eradicate the carrier state. 34/36 patients who fulfilled the criteria for inclusion in the study were evaluable for efficacy, 16 in the pivampicillin/pivmecillinam group and 18 in the placebo group. Seven patients in the pivampicillin/pivmecillinam group had to terminate the treatment after 10-25 days because of adverse reactions, mainly exanthema and nausea. After therapy 8/16 patients treated with pivampicillin/pivmecillinam and 4/18 patients treated with placebo had negative stool cultures for Salmonella species during a mean follow-up time of 13 and 20 weeks, respectively. No abnormalities could be found in those patients who did not respond to therapy except for earlier cholecystectomy in two patients, both in the pivampicillin/pivmecillinam group.
