RESUMO
The diagnosis of sarcoidosis in a patient living with HIV infection is an uncommon event and a challenge for clinicians. Clinical manifestations are variable and fluctuating depending to adherence to ARV therapy and to the level of CD4 count. We analyze here one chronic case in which sarcoidosis appeared clinically two years after pulmonary tuberculosis. The course of the disease was influenced and prolonged by frequent interruptions of antiretroviral therapy. Moreover the diagnosis and the decision to treat have been delayed by the need of exclusion of other pathologies, principally tuberculosis reactivation/reinfection, other mycobacterial diseases, hematologic malignancies. We propose a simplified flowchart for diagnosis and follow up of sarcoidosis, which may also be applied to patients with HIV infection. Diagnosis of latent tuberculosis infection (LTBI) may be difficult in these patients, because the immunological paradox of sarcoidosis. For this reason, following exclusion of active tuberculosis, we advise to submit all sarcoidosis patients to IPT (isoniazid preventive therapy), when immunosuppressive therapy is started.
RESUMO
Coccidioidomycosis is a fungal infection caused by the Coccidioides species, which is endemic in the deserts of the southwestern region of the United States, northern Mexico, and in some areas of Central and South America. We describe a case of pulmonary coccidioidomycosis in a 49-year-old Italian man who came to our hospital with fever and joint and muscle pain 10 days after his return to Italy from Venezuela. Computer Tomography revealed multiple bilateral pulmonary nodules with mediastinal lymphadenopathy. Pulmonary coccidioidomycosis was diagnosed by a serological test, and fluconazole was immediately started. The patient improved within 2 weeks, with complete clinical recovery after 6 months of therapy. This case appears to be part of a large serologically unconfirmed outbreak. In order to provide early diagnosis and treatment, healthcare providers should be aware of coccidioidomycosis, even in travellers returning home from short trips to endemic areas.

Artemisinin and its derivatives are essential components of artemisinin-based combination therapies for treating severe falciparum malaria. In this paper, we describe the occurrence of haemolysis after oral artemether-lumefantrine treatment. To the best of our knowledge, this is the second reported case of a patient affected by severe falciparum malaria with haemolytic anaemia that is likely associated with oral artemether-lumefantrine treatment.

Mediterranean spotted fever (MSF) is an acute febrile, zoonotic disease caused by Rickettsia conorii. MSF is considered a relatively benign disease, but severe complications occur occasionally. However, reports of ocular involvement are few. We describe a case of retinal manifestation in a patient with R. conorii infection.

Imported malaria is the most common cause of fatal infections in returning travellers. The increased amount of both tourist movement and migration has resulted in a growing number of people at risk of infection. In the present study, 507 malaria patients admitted to Italy's National Institute for Infectious Diseases in Rome between January 1984 and December 2003 were studied. Overall, 445 cases, or 87.7%, were acquired in Africa, of which 55% were acquired in five sub-Saharan countries. Plasmodium falciparum accounted for 393 (77.5%) of the imported cases. Patients consisted of short-term travellers (n = 213, 42%), long-term visitors (n = 134, 26.4%), and immigrants from endemic areas (n = 137, 27%). Malaria chemoprophylaxis was completed in less than one-quarter of all patients, with immigrants having the lowest rate of completion: only 3.6% of immigrants fully completed chemoprophylaxis compared to 31% of short-term travellers and 29.1% of long-term visitors (p < 0.001). Upon multivariate analysis, the lack of chemoprophylaxis was independently associated with the occurrence of severe malaria (p = 0.009). Severe malaria was reported in 59 (11.6%) individuals: all 11 deaths due to severe P. falciparum infection occurred in patients from sub-Saharan countries, two of whom were immigrants from countries where malaria is endemic. Malaria poses a serious health threat to individuals visiting endemic areas. Ensuring the correct chemoprophylaxis for all travellers, including immigrants from endemic areas, and providing prompt access to healthcare providers for unhealthy returning travellers are major points still to be addressed in Italy.

BACKGROUND: To investigate if high dose inhaled beclomethasone dipropionate started early after upper respiratory tract infection (URTI) could reduce recurrent wheezing in infants. METHODS: Twenty-six ambulatory infants, 7-12 months of age, with recurrent wheezing during upper respiratory tract infection participated. All experienced at least three wheezing attacks. Those with underlying lung or systemic disease were excluded. Infants were divided into two groups in an open unblinded manner, until 13 patients had been recruited for each group. The groups were similar in risk factors for recurrent wheezing. Four treatment periods of 5 days were planned for group 1. The dose regimen was nebulized beclomethasone 400 mg by mask tid for 5 days. Treatment was started at the very first sign of URTI prior to any sign of wheezing. Group 2 did not receive any preventive treatment and constituted the control group. Symptoms scores were recorded. The number of emergency room visits, hospital admissions and short courses with oral steroids was also noted. RESULTS: Twelve infants completed 48 treatment periods. Five visited the emergency room, only one during beclomethasone therapy. Six received oral steroids, two receiving beclomethasone. No patient was admitted to the hospital. Symptom scores were significantly lower during beclomethasone treatment (p<0.05). No apparent adverse events were reported. CONCLUSIONS: The infant with recurrent wheezing during URTI is a therapeutic challenge. Most of these infants have prodromal symptoms for about 24 hours before wheezing starts. In the present study we observed favorable results, decrease in the number the child wheezed and the number of acute attacks, when high dose inhaled beclomethasone is administered during this critical time.

Jaw-thrust and bag-mask ventilation usually provide adequate oxygenation in patients with acute infectious upper-airway obstruction (AIUAO). It is the treatment of choice for patients on the way to hospital or in an emergency department until definitive stabilization is achieved with available resources. We report three fatal case studies showing ineffective bag-mask ventilation in AIUAO that raise concerns over this treatment. Case 1 is a 4-year-old patient with epiglottitis who suffered complete obstruction during transport to the hospital. Case 2 is a 3-year-old patient with epiglottitis who suffered complete obstruction during transport to the hospital. Case 3 is a 3-year-old child with viral laryngotracheitis and respiratory arrest just after the admission. Should the approach of bag-mask ventilation in AIUAO change to ventilate patients in the prone position? This approach offers two advantages. First, gravity helps the epiglottis fall forward, reducing the airway obstructions. Second, if the patient vomits during ventilation, the vomit will fall to the floor. During bag-mask ventilation in patients with severe partial airway obstruction, ventilation pressure is high. Gastric inflation may occur and rapidly distend the stomach. This gastric distension interferes with ventilation by elevating the diaphragm, resulting in a decreased lung volume. Cricoid pressure could prevent gastric distension in these instances and should be recommended.

The Authors describe the intraosseous administration of drugs and fluids in two patients: a preterm infant (gestational age 26 weeks, weight 850 g) with severe cardiopulmonary depression just after delivery, and a 15-day-old newborn with bronchopneumonia. The intraosseous infusion is safe and effective. At present, mainly in United States, it has an important role in pediatric emergency. It is indicated in all emergency situations where a vascular access must be rapidly obtained and in whom other methods of access to the vascular system have failed. After a short review on the history of this old procedure, used for the first time in 1922 for blood transfusions, the Authors describe its physiology, technique, complications, and contraindications.

We report the results of a study held between 1986 and 1988 on a population constituted by 493 subjects (425 of Mozambican nationality) all living in the camp organized for the building of the dam in Corumana (Sabiè district, Maputo). We found five subjects, all of them from Mozambique, seropositive for HIV-1 antibodies (ELISA and WB) with a prevalence of 1.2%. Four of the positive samples came from female subjects (1.7% of 239 females tested); one positive sample came from a male subject (0.5% of 186 tested).
