Medical education of hypertensives as well as of other asymptomatic cardiovascular risk patients requires individualized, interactive and attractive strategies. Electronic teaching set up in hospital or clinic settings opens the way of the future, saving time and allowing more advantageous use of caretakers. ISIS (Initiation Sanitaire Informatisee et Scenarisee), a French computer assisted program for cardiovascular risk patients, combines a scientific information, divided in 12 sequential but independent modules, with a recreative imaginary trip in the world of ancient Egypt. To test the impact of this tool on patient health information retention, 158 hypertensives hospitalized in a day-hospital clinic were randomized into an intervention or ISIS group (IG, n = 79) and a control group (CG, n = 79). Both groups received cardiovascular education through standard means. In addition, IG patients underwent a 30 to 60 min session on the computer. Cardiovascular knowledge was tested by a nurse administering a standardized 28-item questionnaire before and two months after education. Retesting was done by telephone interview. A total of 138 completed questionnaires (69 from each group) were analyzed. Overall mean cardiovascular knowledge score before education (14.3 +/- 4.2, range 4-25) improved significantly after education (3.7 +/- 3.5, p = 0.0001). This improvement was more important in the IG than the CG (3.8 +/- 3.6 vs 2.4 +/- 3.2 respectively, p = 0.02), especially in hypertensives having a known disease for more than six months. Isis is now available in two languages: French and English. Patients' satisfaction and the conclusion of this comparative trial encourage confirmation of these first results in other French or English speaking populations, in order to test the long term effects of structured electronic teaching sessions on health behaviour, and to promote a wide use of computers and multimedia communication in hypertension control programs.

Overall seventy-two engine-drivers with borderline arterial hypertension (BAH) and stage I arterial hypertension (AH) were studied for the condition of the sympathoadrenal and kinin systems before and after trip. Both groups exhibited a rise in the activity of the sympathoadrenal system before trip, with still greater rise being recordable after trip. BAH and stage I AH subjects demonstrated an increased activity of the kinin system of the kidneys before trip and decreased one after trip. Suppression of the kinin system of the kidneys with simultaneous progression of pressor effects leads to decline in adaptation to physical and psychoemotional overloads in those engine-drivers presenting with early stages of AH.

A 73-year-old African American female presented to our clinic with painful lower extremity lesions of 2 weeks duration. She was in her usual state of health until 3 months prior to presentation when she reported symptoms of fatigue and weakness. She also noticed an enlarging mass on the left side of her neck. She denied fevers, chills, night sweats or cough. Her symptoms were unresponsive to a course of oral dicloxacillin. The neck mass enlarged over 8 weeks and she was referred to our institution for evaluation. CT scan of the neck showed an enlarged lymph node. Ten days prior to her presentation in dermatology, a fine needle aspirate of the enlarging lymph node revealed necrotizing granulomas. Tissue was sent for routine mycobacterial and fungal cultures. Routine blood work, chest radiograph, and a tuberculin skin test were also performed. At the time of her dermatology visit she described the development of multiple new painful, non-pruritic lesions, bilaterally on the lower extremities. She also reported a red crusted area that appeared at the site of her tuberculin test that was placed subsequent to the development of her lower extremity lesions. Her past medical history was significant for Parkinson's disease, hypothyroidism and hypertension. Her current medications included l-thyroxine, estrogen and diltiazem. Her travel history was only remarkable for a trip to Jamaica the previous spring. She was born and raised in Haiti. She reported a history of a positive tuberculin skin test 20 years ago, but received no therapy. Physical examination revealed a 2 x 3 centimeter firm, nontender left lateral neck mass (Fig. 1). Her right forearm revealed an erythematous, ulcerated, indurated plaque 1.5 cm in diameter (Fig. 2.). Her lower extremities revealed tender 0.5 to 1 cm erythematous nodules below the knees bilaterally (Fig. 3). A punch biopsy of a lower extremity nodule revealed a mild pervisacular dermal infiltrate. Within the subcutaneous tissue there was septal widening. There was also a lymphohistiocytic infiltrate with a slight admixture of neutrophils within the septa of the fat lobules. There was no evidence of necrotizing vasculitis or collagen necrosis. An acid-fast stain was not performed. The histologic findings were consistent with a diagnosis of erythema nodosum. Her laboratory evaluation including CBC, electrolytes, thyroid studies, angiotensin converting enzyme level and chest radiograph were normal. Approximately 1 week after her dermatological evaluation, the fine-needle aspirate culture grew Mycobacterium tuberculosis. A diagnosis of tuberculous lymphadenitis associated with erythema nodosum was confirmed. The patient was started on quadruple therapy of isoniazid, rifampin, ethambutol and pyrazinamide. Her lower limb skins lesions rapidly resolved over the subsequent month and her neck mass also diminished in size. She completed 6 months of antituberculous therapy with complete resolution of her lymphadenopathy.

An autopsy case of sudden death due to pulmonary thromboembolism after a car trip is reported. A 56-year-old Japanese man with hypertension and atrial fibrillation suddenly died immediately after having driven for two and a half hours. At autopsy, the pulmonary arteries were found to be filled with dark-red, coiling thrombi consisting of fibrin and red blood cells. In the dilated right popliteal vein, a thrombus consisting of fibroblasts, a large number of collagen fibres, and newly formed capillaries was attached to the vessel wall. The cause of death was determined to be pulmonary embolism due to the thrombus of the right popliteal vein. Two and a half hours of prolonged sitting while driving a car encouraged thrombus formation. We believe that this case, the first autopsy case of fatal pulmonary thromboembolism after a car trip to be reported, highlights the importance of predicting venous thrombosis of the leg or fatal venous thromboembolism after a car trip.

Three important findings emerge from this study using New Immigrant Survey data to examine dietary change and health among Hispanic immigrants. First, individuals who have been in the United States longer report a greater degree of dietary change. Second, after controlling for behavioral characteristics and preexisting diet-related conditions (diagnoses of high blood pressure and diabetes prior to coming to the United States), more dramatic levels of change in diet are associated with higher measures of body mass index. Based on respondents' comparisons of their current health to their health just prior to their most recent trip to the United States, change in diet as a result of immigrating to the United States is positively correlated with both better health and worse health. Among individuals reporting greater levels of dietary change, those with worse health have been in the United States for longer and are more likely to report the use of English at work than those reporting better health, factors that indicate acculturation and exposure to broader U.S. society.

Panama is a beautiful country with many disparities. It was estimated in 1995 that 40% of the population lived in poverty. Deaths from cardiovascular disease increased by 2% annually from 1990 to 1994, with hypertension being the leading cause of death for persons aged 60 years or more. I had the opportunity to travel briefly in Panama on a mission trip and found elevated blood pressure to be a major symptom of the clinic participants.

The paper raises the question as to whether essential hypertension should be included into a list of occupational diseases (intellectual, sensory, and emotional workloads and working conditions) in engine crew members. In the engine crew members of the South-Eastern Railway, the cases and days lost because of illness and temporary disability are higher than those in the whole railway. 32% of the engine drivers (assistants) are followed up for diagnosed essential hypertension. Hypertension (49.7%) is the main reason for suspending engine crew members from work as evidenced by train pre-trip medical examinations. The working conditions (noise, infrasound, mcroclimate) in train engineer's cabs do not meet the sanitary requirements; in this connection the occupational disease sensorineural hearing loss is also registered.

Health safety during trips is based on previous counseling, vaccination and prevention of infections, previous diseases or specific problems related to the destination. Our aim was to assess two aspects, incidence of health problems related to travel and the traveler's awareness of health safety. To this end we phone-interviewed faculty members of a large public University, randomly selected from humanities, engineering and health schools. Out of 520 attempts, we were able to contact 67 (12.9%) and 46 (68.6%) agreed to participate in the study. There was a large male proportion (37/44, 84.1%), mature adults mostly in their forties and fifties (32/44, 72.7%), all of them with higher education, as you would expect of faculty members. Most described themselves as being sedentary or as taking occasional exercise, with only 15.9% (7/44) taking regular exercise. Preexisting diseases were reported by 15 travelers. Most trips lasted usually one week or less. Duration of the travel was related to the destination, with (12h) or longer trips being taken by 68.2% (30/44) of travelers, and the others taking shorter (3h) domestic trips. Most travelling was made by air (41/44) and only 31.8% (14/44) of the trips were motivated by leisure. Field research trips were not reported. Specific health counseling previous to travel was reported only by two (4.5%). Twenty seven of them (61.4%) reported updated immunization, but 11/30 reported unchecked immunizations. 30% (9/30) reported travel without any health insurance coverage. As a whole group, 6 (13.6%) travelers reported at least one health problem attributed to the trip. All of them were males travelling abroad. Five presented respiratory infections, such as influenza and common cold, one neurological, one orthopedic, one social and one hypertension. There were no gender differences regarding age groups, destination, type of transport, previous health counseling, leisure travel motivation or pre-existing diseases. Interestingly, the two cases of previous health counseling were made by domestic travelers. Our data clearly shows that despite a significant number of travel related health problems, these highly educated faculty members, had a low awareness of those risks, and a significant number of travels are made without prior counseling or health insurance. A counseling program conducted by a tourism and health professional must be implemented for faculty members in order to increase the awareness of travel related health problems.

Patients with borderline health should consult a physican before travelling to altitude. The physician will need to know the duration of the trip, ascent profile and how much exercise the patient plans to undertake. The presence of comorbid diseases which reduce oxygenation and ventilation should also be taken into account. Every patient must be assessed on an individual basis, there are no clinical investigations which reliably predict outcome at altitude. Complex cases may require advice from the patient's cardiologist. Travelling from sea level to an altitude of 2,500 m causes a 20% reduction in the partial pressure of inspired oxygen. There is an initial net increase in myocardial oxygen consumption during the first 3-5 days, this then falls as cardiac output on exercise is reduced. During this time patients with angina pectoris may become symptomatic at a lower level of exercise than at sea level and should be advised to reduce their activity. After five days at 2,500 m, the exertion threshold returns to sea level values. Patients should not travel to high altitude immediately after an acute coronary syndrome. Most patients with stable coronary artery disease with a sufficiently high exercise capacity at sea level can go as high as 3,000-3,500 m with only a minimally increased risk. Patients with heart failure have a greater reduction in exercise performance than healthy people at altitude. Patients with mild to moderately impaired systolic LVF and mild symptoms may travel up to 3,000-3,500 m for a day trip. Patients with poorly controlled hypertension should not travel to high altitude. Those with controlled hypertension should consider taking their own blood pressure during a stay at altitude.

Babesiosis is a tick-borne illness caused by the intraerythrocytic parasite Babesia microti. Adult respiratory distress syndrome (ARDS) is a complication of B. microti infection and generally presents later in the course of the disease. We present a case of babesiosis presenting with ARDS. A 59-year-old male with history of hypertension and atrial fibrillation presented with one day of progressive shortness of breath. The patient returned from a trip to Massachusetts one day prior. On arrival to the emergency department (ED) the patient was noted to be febrile with tachycardia, tachypnea, and hypoxia and was intubated for respiratory failure. A computed tomography angiography (CTA) was negative for pulmonary embolism and showed bilateral infiltrates. The Berlin criteria for severe ARDS were met. Tick-borne illness was suspected and Wright-Giemsa stained thin blood smear confirmed the diagnosis of babesiosis. The patient was treated with atovaquone and azithromycin for seven days and was successfully extubated on day four of hospitalization. He continued to clinically improve and was discharged home four days later. The case highlights the importance of physicians being aware of the manifold ways in which babesiosis can manifest.
