The epidemiology, pathogenesis, clinical features, and treatment of Rocky Mountain spotted fever are reviewed. Rocky Mountain spotted fever is a severe infection caused by Rickettsia rickettsii transmitted to man by various species of ticks. High-incidence areas exist in the southeast and south central United States. Only 60-70% of patients with the disease report a history of tick bite or exposure to tick-infested areas. The disease is initially characterized by fever, headache, gastrointestinal complaints, myalgia, and a generalized rash. In several days generalized vasculitis may lead to periorbital edema and nonpitting edema of the face and extremities. Central nervous system involvement is common. Because signs and symptoms associated with the disease are nonspecific, the diagnosis is often delayed or missed. Traditionally diagnostic confirmation relied on serologic testing, but an indirect fluorescent antibody assay will soon be commercially available. Rocky Mountain spotted fever is usually treated with the rickettsiostatic agents chloramphenicol or tetracycline, but few comparative data on these agents in patients with the disease are available. For patients who cannot tolerate oral medications, intravenous chloramphenicol sodium succinate is the preferred treatment; chloramphenicol is also the drug of choice for children less than eight years of age. Otherwise, oral tetracycline hydrochloride is the drug of choice. Antibiotic therapy should be continued for 7-10 days or until the patient is afebrile for two to five days. All cases of Rocky Mountain spotted fever must be reported to the Centers for Disease Control. The best ways to decrease the morbidity and mortality of the disease are to increase awareness of its signs and symptoms and to prevent exposure to ticks.

Cavernous sinus thrombosis may occur as a complication of infectious and noninfectious processes. Septic thrombosis of the cavernous sinuses most commonly follows infections of the middle third of the face due to Staphylococcus aureus. Other antecedent sites of infection include paranasal (usually sphenoid) sinusitis, dental abscess and, less often, otitis media. Fever is a nearly constant finding, but headache may not be prominent. Periorbital edema, chemosis, proptosis, and limitation of extraocular movements (especially lateral gaze) develop in almost all recognized cases. Involvement of the opposite eye frequently appears within two days following the onset of unilateral signs. Although computed tomography may be helpful, magnetic resonance imaging is probably the diagnostic procedure of choice. Treatment includes appropriate antibiotics and, oftentimes, surgical drainage of the primary focus of infection. Less than half of the patients recover completely; the mortality rate is approximately 30%.

Lyme disease typically begins with a unique skin lesion, erythema chronicum migrans (ECM) (stage 1). Patients with this lesion may also have headache, meningeal irritation, mild encephalopathy, multiple annular secondary lesions, malar or urticarial rash, generalized lymphadenopathy and splenomegaly, migratory musculoskeletal pain, hepatitis, sore throat, non-productive cough, conjunctivitis, periorbital edema, or testicular swelling. After a few weeks to months (stage 2), about 15% of patients develop frank neurologic abnormalities, including meningitis, encephalitis, cranial neuritis (including bilateral facial palsy), motor or sensory radiculoneuritis, mononeuritis multiplex, or myelitis. At this time, about 8% of patients develop cardiac involvement--AV block, acute myopericarditis, cardiomegaly, or pancarditis. Throughout this stage, many patients continue to experience migratory musculoskeletal pain in joints, tendons, bursae, muscle, or bone. Months to years after disease onset (stage 3), about 60% of patients develop frank arthritis, which may be intermittent or chronic. Recently evidence suggests that Lyme disease may also be associated with chronic neurologic or skin involvement. Thus, Lyme disease occurs in stages with different clinical manifestations at each stage, but the course of the illness in each patient is highly variable.

A case is presented of a 32-year old gravida 3, para 1, ab 1, presented at 26 weeks with chief complaints of periorbital edema, headaches, and blurred vision for about 1 week. 2 weeks prior to admission she had experienced shortness of breath and decreased fetal movement. Admission was at 28 weeks with uncontrolled hypertension, blood pressure 190/120, pulse 100/min. Temperature was 98.8 degrees. Attempted induction of labor with oxytocin was unsuccessful. A hydralazine infusion decreased the blood pressure to 180/100 and a 20 mg prostaglandin (PG) E2 suppository was inserted. A few hours later the blood pressure had dropped to 100/60 and the hydrazaline infusion was discontinued. About 3 hours later a stillborn female infant was born; post delivery examination revealed a large gap in the wall of the uterus extending into the lateral vaginal fornix. A total abdominal hysterectomy and right salpingo-oophorectomy was then performed and recovery was uneventful. PGE2 reliably initiates labor even in the presence of an "uninducible cervix" and is prone to increase intrauterine pressure to a level beyond that of normal labor with a lag in cervical changes. The 2 most common traumata reported following PG administration for therapeutic abortion are either cervico-vaginal fistulas or lateral tears. In this case since there was no indication of any congenital weakness of the uterine wall, it is reasonable to assume that the mechanism leading to the rupture was intense and prolonged uterine contractions combined with a rigid cervix.

Lyme disease, caused by a tick-transmitted spirochete, typically begins with a unique skin lesion, erythema chronicum migrans. Of 314 patients with this skin lesion, almost half developed multiple annular secondary lesions; some patients had evanescent red blotches or circles, malar or urticarial rash, conjunctivitis, periorbital edema, or diffuse erythema. Skin manifestations were often accompanied by malaise and fatigue, headache, fever and chills, generalized achiness, and regional lymphadenopathy. In addition, patients sometimes had evidence of meningeal irritation, mild encephalopathy, migratory musculoskeletal pain, hepatitis, generalized lymphadenopathy and splenomegaly, sore throat, nonproductive cough, or testicular swelling. These signs and symptoms were typically intermittent and changing during a period of several weeks. The commonest nonspecific laboratory abnormalities were a high sedimentation rate, an elevated serum IgM level, or an increased aspartate transaminase level. Early Lyme disease can be diagnosed by its dermatologic manifestations, rapidly changing system involvement, and if necessary, by serologic testing.

Chronic rhinosinusitis occurs to 5% of the population with upper respiratory infections. The objective of this study is to know the main symptoms in a pediatric population younger than 14 years with the diagnosis of chronic rhinosinusitis, to know age and sex distribution and evolution. We did a medical history, physical examination, nasal cytology, skin tests and sinus X rays in each of 100 patients. Results the main symptoms were: cough, halitosis, postnasal discharge, fever, headache, sore throat, facial sensitivity and periorbital edema. This findings predominated in males and the average evolution time was 1-2 years.

The cavernous sinus is most frequently involved by septic thrombosis. The common sites of primary infection are the medial face, orbits, tonsils, soft palate, sphenoid and ethmoid sinuses. The usual clinical presentation begins with fever and periorbital edema followed by headache, ptosis and ocular muscles palsy. The diagnosis is usually made on clinical grounds. Treatment consists of eradication of the primary source of infection and the administration of antibiotics and anticoagulants. We report six cases of septic thrombosis of cavernous sinus.

A case of pituitary apoplexy, which was initially misdiagnosed as 'acute frontal sinusitis', is reported. The presenting symptoms and signs of the patient were headache, moderate fever, left periorbital edema, marked tenderness over the left frontal sinus and purulent secretion over the left middle turbinate and nasopharynx. These clinical symptoms were wrongly perceived as complicated frontal sinusitis. The CT scan and the elective right carotid angiography showed a pituitary adenoma. Therefore pituitary apoplexy of a preexisting pituitary adenoma was diagnosed. The patient underwent surgical removal of the adenoma and his postoperative course was uneventful. Thus otolaryngologists should consider pituitary apoplexy in the differential diagnosis of pathologies concerning the anatomic area of the anterior cranial fossa.

Trichinellosis is a worldwide zoonotic disease caused by a nematode Trichinella sp. Cases of Trichinella spiralis infection in Slavonski Brod were investigated. A total of 64 trichinellosis cases were notified to the Institute of Public Health, Brod-Posavska County between October and November 2004. There were 64 patients, 32 of them female, age range 3-67, mean 35 years. The mean incubation period was 3 (range 1-5) weeks. The epidemic started in October and terminated 39 days later. The patients ate smoked sausages. Trichinella spiralis was identified in sausages by artificial digestion. Among 64 people infected, 65% had facial and/or periorbital edema, 56% diarrhea, 53% myalgia, 48% fever, 26% headache, 23% weakness, 6% conjunctivitis, 6% cough and 3% vomitus, 6% of patients were free from symptoms and 17% were hospitalized. Eosinophils were elevated in 92%, creatinine kinase in 60%, and lactate dehydrogenase in 59% of patients; 97% of patients were positive for Trichinella spiralis on indirect immunofluorescence.
