RESUMO

A 34-year-old female clinical virology assistant was punctured with a contaminated lancet used for sampling from a suspected Hand, Foot, and Mouth disease (HFMD) patient. Five days after a puncture, the disease symptoms manifested, including high fever, ague, and stiff neck. Skin rashes suddenly appeared after day 6. Stiff neck and fever were relieved two days after the rash appeared, and rashes disappeared gradually by the next five days. Samples for molecular detection and virus cultivation were taken from the patient. Real-time PCR found the enteroviral RNA in the throat swab and skin rashes. The specific CPE of Enteroviruses appeared on the Vero cell line after three days of incubation. In this case transmission occurs through needle injury and results in the systemic disease, so unusual and unexpected viral transmission should be considered when dealing with samples.

RESUMO

Mucocutaneous leishmaniasis, which mostly occurs in the New World, is mainly associated with Leishmania braziliensis and to a lesser degree L. panamensis and L. amazonensis infections. Primary mucosal leishmaniasis is very rare in Iran in spite of high prevalence of cutaneous and visceral leishmanisis. A nine-year-old boy had cutaneous leishmaniaisis for five years involving the left side of his face; he then developed swelling and ulceration of the lip and left side buccal mucosa five months before hospital admission. He had severe swelling of the lower lip and there was ulceration and bleeding of the buccal mucosa. Direct smear revealed leishman bodies and nested PCR confirmed the presence of kinetoplast DNA of L. major in the oral mucosal specimen. The patient received amphotericin B deoxycholate 1 mg/kg/day for one month. The lip and face inflammatory reaction disappeared to nearly normal after one month of therapy. The patient was discharged with ketoconazole (5mg/kg/day) for six weeks. To our knowledge, this is the first report of mucocutaneous leishmaniasis caused by L. major in Iran.

RESUMO

BACKGROUND: Hajj is a mass gathering undertaken annually in Mecca, Saudi Arabia. The 2009 Hajj coincided with both the pandemic influenza A/H1N1 2009 (A(H1N1)pdm09) and seasonal types of influenza A viruses. The interaction between pandemic influenza and Hajj could cause both a high level of mortality among the pilgrims and the spread of infection in their respective countries upon their return home. OBJECTIVE: The present study attempted to determine the point prevalence of A(H1N1)pdm09 among returning Iranian pilgrims, most of whom had been vaccinated for seasonal influenza but not A(H1N1)pdm09. METHODS: Pharyngeal swabs were collected from 305 pilgrims arriving at the airport in Shiraz, Iran. RNA was extracted from the samples and A(H1N1)pdm09 and other seasonal influenza A viruses were detected using TaqMan real-time PCR. For A(H1N1)pdm09-positive samples, the sensitivity to oseltamivir was also evaluated. RESULTS: Subjects included 132 (43.3%) men and 173 (56.7%) women, ranging in age from 24 to 65 years. The A(H1N1)pdm09 virus was detected in five (1.6%) pilgrims and other influenza A viruses in eight (2.6%). All the A(H1N1)pdm09 were sensitive to oseltamivir. CONCLUSIONS: Only five cases were found to be positive for A(H1N1)pdm09, and it seems unlikely that the arrival of infected pilgrims to their homelands would cause an outbreak of a new wave of infection there. Thus, the low morbidity and mortality rates among the pilgrims could be attributed to the characteristics of A(H1N1)pdm09, which causes morbidity and mortality in a way similar to the seasonal influenza infections, absence of high-risk individuals among the Iranian pilgrims, and the instructions given to them about contact and hand hygiene, and respiratory etiquette.

RESUMO

Abstract. Secondary bacterial infections are a major complication and cause of death in children with visceral Leishmaniasis (VL). Thus, early diagnosis of bacterial infections is an important step in the treatment of patients with VL. The goal of this study was to determine if serum procalcitonin (PCT) could be used as a diagnostic marker of secondary bacterial infections in VL patients. Serum PCT was measured in 35 hospitalized patients with VL before treatment and after defervescence. The level was higher than normal (> 0.5 ng/mL) in 72% (25) of the patients. Twelve (34%) of 35 patients had secondary bacterial infections with PCT levels ranging from 0.1 to 12.29 ng/mL, and those without secondary bacterial infections (23) had PCT levels ranging from 0.1 to 14.58 ng/mL. The results suggest that PCT levels increase significantly in most VL patients but are not correlated with the presence of secondary bacterial infections.

RESUMO

Visceral leishmaniasis (VL), caused by Leishmania infantum, is endemic in southern Iran. To detect asymptomatic individuals, we used kinetoplast DNA (kDNA) polymerase chain reaction (PCR)-ELISA methods on 388 blood samples of healthy persons in two endemic loci and compared the results with the leishmanin skin test (LST) and the immunofluorescent antibody test (IFAT). kDNA PCR, LST, and IFAT were positive in 95 (24.5%), 132 (34%), and 212 (54.6%) cases, respectively. Fifty-five (21.4%) individuals that were LST negative were PCR positive. All PCR-positive individuals had a titer of >or=1:20, whereas 45% of those that were IFAT positive were PCR positive. For a reliable index of prevalence rate of infection, LST alone is not sufficient and needs to be accompanied by PCR-ELISA. The high rate of kDNA-positive results may indicate the possibility of humans being a reservoir and source of transmission. In endemic areas, kDNA PCR-ELISA is not a reliable test for the diagnosis of active VL.
