Background: Zoonotic cutaneous leishmaniasis (ZCL) is a polymorphic disease which may show various clinical manifestations. Although genetic variability of the parasite is suggested to be one of the factors influencing clinical manifestations in leishmaniasis, no data exist regarding genetic polymorphism of Leishmania major. Therefore, determination of genetic variation within the species of L....

Recent studies indicate a high prevalence of seropositivity to the lymphadenopathy-associated virus/human T-lymphotropic virus (type III) among individuals with hemophilia exposed to clotting factor concentrates prepared from large donor pools. The peripheral blood lymphocytes of 19 young seropositive patients with inherited bleeding disorders were examined for the presence of this virus by coc...

BACKGROUND AND OBJECTIVES A diverse group of Escherichia coli are known as enterohemorrhagic Escherichia coli (EHEC) including O157:H7 and non-O157 EHEC. Enterohemorrhagic strains are related to sever clinical conditions in humans including hemorrhagic colitis and hemolytic uremic syndrome, and most of the recorded outbreaks occurred due to O157: H7 E. coli. The aim of the present study was to ...

Toxic shock-like syndrome (TSLS) is characterized by hypotension or shock, fever, multiorgan system involvement, and a concurrent group A streptococcal infection. We analyzed 34 streptococcal strains isolated from patients with clinically well-documented TSLS for their pyrogenic toxin profiles and M-protein types. Although strains of nine different M types were represented in the sample, 74% of...

The effects of the CultureSwab (Difco Laboratories, Detroit, Mich.) and Culturette II (Marion Scientific, Div. Marion Laboratories, Inc., Kansas City, Mo.) transport systems on the viability of 95 clinically significant bacteria were studied. Organisms included staphylococci (8 isolates), streptococci (22 isolates), Haemophilus spp. (16 isolates), members of the family Neisseriaceae (14 isolate...

a 3-year-old girl was presented with periorbital edema, hypertension, proteinuria, and hematuria. she recovered clinically after 9 days with normal urinalysis. during the follow-up, she developed recurrent episodes of nephrotic syndrome. the kidney biopsy revealed mild mesangial proliferation and a low dose of prednisolone could effectively control the disease. iran j med sci 2005; 30(1): 38-40...

AIM This study was conducted to determine the prevalence and antimicrobial susceptibility of Streptococcus suis and their resistance patterns isolated from both clinically healthy carriers and diseased pigs in and around Guwahati, Assam, India. MATERIALS AND METHODS A total of 497 samples were collected during October, 2012, to April, 2014, from clinically healthy (n=67) and diseased (n=230) ...

Because of the declining frequency of anaerobic bacteremia, routinely using half the collected blood volume for anaerobic culture has been challenged. There is no data indicating whether more clinically relevant isolates would be recovered if all or most of the given blood sample were cultured aerobically. In this two-part study, we reviewed cases of anaerobic bacteremia to determine what propo...

the silent sinus syndrome (sss) involves painless facial asymmetry and enophthalmos, which is theresult of chronic maxillary sinus atelectasis. in most cases, it is diagnosed clinically, however, usingthe characteristic imaging features including maxillary sinus outlet obstruction, sinus opacification,and sinus volume loss caused by inward retraction of the sinus walls. obstruction of the maxil...

case presentation the current report presented an eight-year-old girl with microscopic hematuria and chronic abdominal pain along with short review of anatomy, pathophysiology, clinical significance and management of this syndrome. conclusions the nutcracker syndrome should be differentiated from unexplained chronic abdominal pain. introduction renal vein entrapment, named nutcracker phenomenon...
