A 35 year old patient presented to the emergency room with high fever, headache and a maculopapular rash after returning from the Canary Islands. Elevated levels of LDH and transaminases and thrombopenia developed during the further hospital course. This presentation is common for an infection with Rickettsia typhi. Therapy with doxycycline is usually effective and should be instituted promptly. The patient's fever remitted 48 h after the first dose. Fever of intermediate duration has been described as a separate disease entity in the Mediterranean region and the Canary Islands. It is defined as fever of 7-28 days duration for which a complete basic workup fails to define an etiology. Most cases are due to one of six infectious diseases (Q fever, Mediterranean spotted fever, endemic typhus, leptospirosis, brucellosis and mononucleosis).

Overseas deployments place military personnel at risk for tropical diseases not typically observed on the U.S. mainland. This case describes the first reported case of brucellosis returning from Operation Enduring Freedom and Operation Iraqi Freedom. A 31-year-old infantry soldier complained of a 6-week history of headaches, relapsing fever, and constitutional symptoms since returning from Iraq. This soldier was determined to have the only reported case of brucellosis, but was one of many soldiers at risk from eating unpasteurized cheese on the local economy. Although malaria and leishmaniasis continue to be the most common deployment-related illnesses, brucellosis must also be considered in the differential of any redeployed soldier with headache, fever, and body aches. Public health as well as command elements must reinforce their role in preventing exposure to this pathogen.

Central nervous system (CNS) involvement is uncommon in brucellosis. Neurological complications of brucellosis may be divided into 2 major groups: 1) those related to the acute-febrile state that occurs in acute disease (toxic-febrile neurobrucellosis), and 2) those related to actual invasion and localization of the pathogen in the CNS (classical neurobrucellosis). In this paper, we present 4 cases of toxic-febrile neurobrucellosis and discuss clinical findings and outcome of treatment in these cases. All patients had fever, headache, stupor or coma with neuropsychiatric symptoms such as hallucination, delirium, convulsion, dysarthria, psychosis, and night raving. Peripheral and cranial vasculitis was present in case 3 and bilateral sensorioneural hearing loss in case 4. Neither pleocytosis nor hyperproteinorrachia was present in any patient in lumbar puncture. Brucella melitensis was isolated in case 3 from bone marrow, and in case 4 both from blood and bone marrow. All patients received combined treatment consisting of ceftriaxone, rifampicin, and doxycycline. They were discharged from the hospital with full recovery. No recurrence or any complaint was observed during the follow-up. In conclusion, despite the rapid course and serious complications, outcome from febrile-toxic neurobrucellosis is excellent especially when effective antimicrobial therapy is started early in the course of illness.

Thrombotic thrombocytopenic purpura (TTP) is characterized by disseminated thrombotic occlusions located in the microcirculation and a syndrome of microangiopathic hemolytic anemia (MAHA), thrombocytopenia, fever, and renal and neurologic abnormalities. Although several factors such as viral and bacterial pathogens, pancreatitis, drugs, collagen-vascular diseases, cancers, and pregnancy have been reported to be associated with TTP, brucellosis is an exceptional cause of this disorder. We represent a 19-year-old woman applying to our outpatient department with the complaints of headache, fever, sweat, malaise, and jaundice. Clinical signs and laboratory findings were consistent with TTP. Brucella agglutination was found to be 1/320 positive. After the administration of therapeutic plasma exchange, all symptoms and laboratory abnormalities improved dramatically. Antibiotic therapy directed to Brucella infection was initiated and no recurrence of TTP was seen.

The pathogenesis of tension-type headache (TTH) is poorly understood. TTH is mostly associated with the sympathetic nervous system. Reports considering autonomic nervous system functioning with regard to TTH are limited. Autonomic nervous system disorders could however play a role in the etiopathology of TTH. Compared with sympathetic nervous system functioning, techniques for evaluating parasympathetic nervous system activity are more limited. Therefore, the aim of the study was to measure heart rate recovery (HRR), an index of vagal activity, in TTH patients. Thirty-seven patients with TTH (15 with episodic and 22 with chronic TTH) and 37 control subjects underwent exercise tolerance testing according to modified Bruce protocol. Heart rate recovery (HRR) at 1 and 3 minutes (HRR1 and HRR3) were calculated. HRR 1 and 3 were found to be similar in patients and controls. However the resting heart rate in patients with episodic TTH was found to be significantly lower than the resting heart rate in patients with chronic TTH and control subjects. These results suggest that parasympathetic nervous system function is not affected in TTH patients. However sympathetic nervous system tonus, which is evaluated by resting heart rate, is low in patients with episodic TTH, suggesting sympathetic hypofunction.

Brucellosis is a common zoonosis in many parts of the world, including Mediterranean and Middle Eastern countries. The disease is primarily related to occupations at risk, such as veterinarians, farmers, laboratory technicians, abattoir workers, and others working with animals and their products. Neurologic complications of brucellosis are quite rare, ranging from 1.7 to 10% of those infected. To date, no cases of neurobrucellosis with hydrocephalus have been reported. A 38-year-old right-handed farmer complained of headaches, nausea, vomiting, gait disturbance, and sweating for 2 days. He also complained of bilateral hearing loss of 4 months duration. On neurologic examination, dysmmetry, dysdiadochokinesis, ataxia on the left, and bilateral sensorineural hearing loss existed. On cranial MRI, a communicating hydrocephalus was noted. Because the patient consumed fresh sheep cheese and was a farmer, brucellosis was considered in the differential diagnosis. Brucella agglutination was positive with a 1/320 titer in the blood and a 1/80 titer in the cerebrospinal fluid. Ceftriaxone, doxycycline, and rifampicin were administered and by the fourth week of treatment, the ataxia was markedly improved, and the patient was able to walk without support. His cranial MRI demonstrated a total regression of the hydrocephalus. As a result, we suggest that neurobrucellosis should be considered in patients with hydrocephalus, especially if they live in an endemic area for brucellosis, even in the absence of other systemic signs.

Over six months, 129 consecutive brucellosis cases were diagnosed in females attending the outpatients' clinics the females in Al-Azhar and Ain Shams Universities Hospitals. Their ages ranged between 12-65 years old. 113 (87.6%) gave history of raw milk consumption, 13 (10%) gave history of home slaughtering of sheep, 2 (1.5%) gave history of animal contact, and one patient gave history of abortion, that partner had brucellosis. A total of 61.2% of patients gave serum agglutination test of 1: 640, who suffered acute or subacute infection. Titers of 1:320 (38.8%) were found in the majority of chronic cases. Causes of endemic parasitosis were excluded. Symptoms were fever (79.5%), headache (72.4%), generalized arthralgia (65.3%), sweating (65.3%), chills (63.8%), backache (34.6%), abdominal pain (27.5%), loss of appetite (25.5%), lassitude (17.2%), myalgia (14.2%), monoarthralgia (7.9%). Spinal involvement was in 15% patients, who had chronic brucellosis. 32/35 were successfully treated with a combination of streptomycin and tetracycline, 17/21 with streptomycin and septrin, 38/43 with tetracycline and septrin, and 26/26 (100%) with rifampicin and tetracycline or septrin, which treated all resistant patients.

Brucellosis is prevalent in North and East Africa, the Middle East, South and Central Asia, South and Central America and the Mediterranean countries of Europe. In 5% of cases it may lead to central nervous system manifestation presenting most often as a meningitis or meningoencephalitis. Here we report and discuss a case of neurobrucellosis with meningitis with cranial nerves neuritis. A 56-year-old German male was admitted with bilateral abducens nerve palsy, amblyacousia and intractable headaches. An enzyme-linked immunosorbent assay (ELISA) revealed antibodies against Brucella in serum and cerebrospinal fluid (CSF). Additionally, our patient suffered from an infarction of the left thalamus. In conclusion, in cases of unresponsive meningitis or meningoencephalitis and history of travel in endemic regions, neurobrucellosis should be considered. If initial microbiological tests fail, complementary investigations such as ELISA are indicated to detect Brucella species in serum and/or CSF.

Brucellosis is an endemic disease in Turkey. Simultaneous infections among family members consuming infected dairy products have been reported. The most frequent signs and symptoms are nonspecific, and most human cases remain unrecognized. We aimed to screen family members of index cases with brucellosis. A questionnaire including demographical and epidemiological data was obtained. All cases were tested by slide agglutination tests (Rose Bengal test). Seropositive ones were further tested by tube agglutination tests (Wrigth test). In the index cases, Brucella antibody titers of > or = 1:160 with and without clinical symptoms and 1:80 with clinical symptoms were considered positive and the household members were enrolled into the study. Twenty-eigth index cases were identified among a total of 110 family members. Among family members, 90 (82%) were seronegative whereas 20 were seropositive. Among seropositive cases, 12 were asymptomatic and 8 were symptomatic. The most frequent symptoms of the index cases were fever, headache and arthralgia. Symptomatic cases were treated and asymptomatic ones followed up without therapy for a period of 6-12 months and none developed brucellosis. In conclusion, family members of the patients with brucellosis are under the increased risk of brucellosis because of a common source. Therefore, it can be considered that family screening may lead to early diagnosis of the disease and to the prevention of the complications.
