In the vast majority of cases infections of the paranasal sinus system are rhinogenic. Usually these spread via the middle nasal meatus and the anterior ethmoid to the dependent larger sinuses, especially to the frontal and/or maxillary sinus. If a sinusitis does not heal or is constantly recurring, a focus of infection has remained in a stenotic cleft of the lateral nasal wall, irritating nasal function and where from infection time and again may spread to the dependent sinuses. These Infection foci may be very circumscribed and limited, and not always must present with the typical triad of sinusitis symptoms: pathological secretion, nasal obstruction and cephalgia. Frequently only one of these symptoms prevails. By the means of nasal endoscopy and polytomography these foci can exactly be localized. After clearing the infection foci, which easily can be achieved under endoscopic guidance, mucosal function usually is restored and the dependent larger sinuses heal without having been touched.

Infection with Ehrlichia canis should be suspected in patients with fever, headache, malaise, leukopenia, thrombocytopenia, and a history of recent exposure to ticks. The cytopenia is caused by bone marrow hypoplasia which may be severe. The disease may be confused with spotless Rocky Mountain spotted fever but can be differentiated from this infection serologically with acute and convalescent sea. In humans, recovery has occurred with and without antibiotic therapy. However, prompt antibiotic therapy is advised prior to serologic studies, especially in immunocompromised individuals, splenectomized persons, and patients with AIDS-who may develop a more overwhelming rickettsial infection.

Infection in the marrow of the temporal, occipital, and sphenoid bones is an uncommon, but increasing occurrence. It is usually secondary to infections beginning in the external auditory canal and is caused almost uniformly by the gram negative Pseudomonas aeruginosa bacteria. Technetium and gallium scintigraphy help in the early detection of such infections while CT scans demonstrate dissolution of bone in well-developed cases. Headache is the predominant symptom. Dysphagia, hoarseness, and aspiration herald the inevitable march of cranial nerves. We have diagnosed and treated 17 cases of osteomyelitis of the skull base. Although the total mortality rate is 53%, it is now a curable disease. Six of our last 8 patients remain alive, although 1 is still under treatment. Treatment is medical and requires the long-term concomitant intravenous administration of an aminoglycoside and a broad spectrum semisynthetic penicillin effective against the causative organism.

A multi-centered clinical study was carried out to evaluate the efficacy of ofloxacin in otorhinolaryngological infections in Japan. Ofloxacin was used at a dosage of 300 mg to 800 mg daily for three to 20 days in 206 cases of various infectious diseases in the otorhinolaryngological field such as otitis media, external otitis, paranasal sinusitis, tonsillitis and pharyngolaryngitis. Its efficacy rate was 79.9%. Minor side effects were seen in three cases (1.5%), gastro-intestinal disorders in two and headache in one. The antibacterial activity of ofloxacin was compared with the activity of pipemidic acid, nalidixic acid and norfloxacin against clinically isolated microorganisms. Ofloxacin was highly superior to pipemidic acid and nalidixic acid, and slightly more active than or equivalent to norfloxacin.

The Ehrlichia are tick-borne rickettsial organisms that cause disease in animals throughout the world but that have been previously recognized as human pathogens only in Asia. We have identified six patients with serological evidence of recent infection with an Ehrlichia: a fourfold or greater rise or fall in titer to Ehrlichia canis. All of the patients reported recent tick bites. Rigors, myalgia, headache, nausea, and anorexia were each reported by five patients. Fever was present in all patients and was accompanied by relative bradycardia and leukopenia in five patients, thrombocytopenia and abnormal liver function test results in four, and anemia in three. Five of the six patients were treated with tetracycline hydrochloride, and all recovered. Infection with Ehrlichia should be considered in patients with unexplained febrile illnesses after tick exposure.

Clinical features, findings of diagnostic studies, results of therapy, and prognostic factors were analyzed in 45 patients with brain abscesses. The number of patients diagnosed yearly has increased since CT scanning became available, but despite the enhanced sensitivity, the time from either onset of symptoms or hospital admission until initiation of therapy was not decreased and there was no dramatic effect upon morbidity or mortality in this series. Infections of paranasal sinuses, ears, lungs, and odontogenic foci were predisposing factors in approximately 70% of cases. Single abscesses, present in 75% of patients, were distributed equally in both hemispheres, with more than half in the frontal and parietal lobes. Common signs and symptoms included headache, fever, chills, seizures, nausea, vomiting, altered sensorium, nuchal rigidity, and localizing neurologic signs. Blood cultures were positive in 11%. Lumbar puncture rarely provided data from which a diagnosis could be established; CSF cultures were positive in only 7% of patients, and there was a 15% temporally associated incidence of brain herniation and death. Diagnostic information was most readily obtained using imaging techniques such as CT and 99mTc scanning, and arteriography was invasive and of no added value. CT scans are however, often initially negative in patients presenting with clinical signs of meningitis presumably following rupture of an abscess into the subarachnoid space, and the average time for changes to appear on CT scan is 9 days. It is, therefore, recommended that when the clinical assessment suggests the possibility of brain abscess the patient be treated empirically with antibiotics and that lumbar puncture be performed only after thoughtful assessment of the risk-to-benefit ratio for each patient. Causative organisms were isolated from more than 80% of abscesses despite prior antibiotic treatment; more than half grew a single pathogen, most commonly streptococci. Anaerobic and microaerophilic bacteria accounted for 62% of all isolates, and were the only organisms in 33% of patients. Computerized tomographic scans in 30 patients showed "ring-enhancing" lesions, nodular enhancement, or areas of low attenuation. Complete resolution of abscesses on CT scans rarely occurred during hospitalization and took as long as 5 months. Decrease in the size of abscesses on CT scan correlated well with clinical improvement and was seen within a week when abscesses were excised, but was often not obvious for 6 to 8 weeks if antibiotics were used alone.(ABSTRACT TRUNCATED AT 400 WORDS)

Thirty adult inpatients were enrolled in an open multicenter study to determine the efficacy and tolerability of mezlocillin injected i.m. in surgical bacterial infections. Clinical, bacteriological and laboratory controls were performed. The infections were caused by gram-negative and/or gram-positive bacteria. Twenty-seven patients were cured bacteriologically and clinically. One patient had a relapse and there was a failure in two. The local and systemic tolerance was very good. One patient experienced nausea, headache and intestinal pain on the second day of treatment. These symptoms subsided spontaneously shortly after mezlocillin treatment was discontinued.

Since 1981 the authors have performed 14 orthotopic heart transplantations and one heart-lung transplantation, using cyclosporine and prednisone as immunosuppressants. Eight of the recipients had terminal congestive cardiomyopathy and six had ischemic cardiac dysfunction. The combined heart-lung transplantation was performed on a patient with a congenital ventricular septal defect with Eisenmenger's syndrome. Twelve of the patients were alive and well at follow-up 9 to 34 months (mean 17.4 months) after transplantation. One patient died of acute rejection and one of acute pancreatitis and secondary peritonitis. The third death, due to acute right ventricular failure, occurred immediately after transplantation. Rejection was diagnosed histologically on seven other occasions in four patients and was treated successfully. Infection was not a major problem. Cyclosporine -induced reversible nephrotoxicity was evident in 12 patients, 2 of whom required dialysis. Other side effects of cyclosporine seen in these patients included hypertension, gastrointestinal upset, headaches and hirsutism. This experience suggests that cyclosporine is a potent immunosuppressive agent that has greatly reduced the hazards of rejection and infection. However, the frequency of nephrotoxicity is high; careful monitoring of cyclosporine blood levels and renal function is essential.

Within a three-year period 712 patients with Campylobacter jejuni infection were diagnosed at our laboratory in Helsinki and 524 (72%) were treated as outpatients. More than half (57%) of the patients became infected when abroad, chiefly during holiday trips in the Mediterranean and in East European countries. The risk of acquiring infection was about 250 times greater abroad than in Finland, and it differed considerably from country to country, being highest in Morocco and Tunisia. Among domestic cases the incidence of infection was significantly higher (p less than 0.001) during the summer and autumn months than during winter or spring. Animal contact prior to infection was reported in 59% of domestic and 31% of imported cases, and previous consumption of poultry in 28% and 42% of those from whom information was obtained. Besides diarrhoea (98%), the main symptoms included abdominal pain (87%), fatigue (81%), fever (78%), malaise (70%) and headache (51%). Arthralgia was observed in 19% and arthritis in 2% of patients. The mean duration of diarrhoea was 10.8 days, of fever 2.8 days.

Tick-bite fever, the variety of tick typhus occurring in southern Africa, is caused by Rickettsia conori var. pijperi and is transmitted by hard or ixodid ticks. It is usually a mild disease, especially in children and young adults, but in middle-aged and elderly patients (and sometimes in young adults) it may assume a severe form. This is characterized by high fever, severe headache, delirium, stupor and occasionally coma, and a profuse maculopapular rash which becomes haemorrhagic and is associated with petechiae in the skin and later, but rarely, by the development of gangrene of the fingers and toes. During these severe attacks the central nervous system may be involved and marked disorders of liver and kidney function sometimes lead to kidney failure and the need for treatment and dialysis in an intensive care unit. Three illustrative cases are described in which diagnosis was delayed. One patient died; 2 patients responded to administration of tetracycline. The danger of allowing tick-infested dogs onto one's bed is stressed. Infections transmitted by dog ticks tend to be more severe than those acquired via ticks from the bushveld, possibly because they so often occur in middle-aged and elderly patients. Serological tests have recently indicated that there are antigenic differences between 'suburban' and 'bushveld' strains; these clearly require further study.
