Background: TRICHOMONIASIS is an extremely common infection worldwide and is associated with important public health problems, including amplification of HIV transmission. This disease is in forms of symptomatic and asymptomatic in women and may depend on host as well as parasite variables. Thus the aim of this study was to evaluate the patients attending gynecology clinic with different symptoms and checked them for Trichomonas vaginalis infection.Methods: The vaginal secretion and urine samples of the patients attending gynecology clinic, Imam Reza Hospital, Amol City, were checked by direct smear and cultured in TYI-S-33 culture media.Results: Out of 853 samples collected, 8(0.9%) were positive for T. vaginalis and the number of asymptomatic patients for TRICHOMONIASIS were 1.3 times more than infected samples belong to symptomatic ones. Per speculum examination revealed that 75% of T. vaginalis positive subjects had normal appearance of vagina and cervix.Conclusion: According to the epidemiological aspects, these asymptomatic patients are very important as healthy carriers, and T.vaginalis infections are commonly associated with other STDs and are a marker of high-risk sexual behavior. Thus laboratories could play important role for diagnosis of infection and help the physicians for properly treatment.

Spleen is an unusual location for hydatid cyst. Here we report a case of primary splenic hydatid cyst in a 41-yr-old Iranian woman from Yasuj, southwest of Iran. The patient had been admitted to Shahid Beheshti Hospital because of abdominal pain. Abdominal sonography revealed a hypoechoic lesion of 150 X 130 mm in the spleen, suggestive of hydatid cyst. Splenectomy was performed for the patient and surgical interventions revealed a hydatid cyst occupying most of splenic parenchyma. She was discharged on the 5 day of her operation. Postoperative diagnosis and confirmation of hydatid cyst was done by histopathological, molecular and serological approaches. Histopathological evaluation revealed the classical laminated layer of hydatid cyst. DNA was extracted from a part of cyst and PCR amplified. Sequencing and analysis of PCR product revealed that the isolate has the most similarity with G1 strain of Echinococcus granulosus. Patient’ s serum was positive for IgG anti-hydatid cyst antibodies, using antigen-B ELISA.

Background: TRICHOMONIASIS, caused by Trichomonas vaginalis, is the most common sexually transmitted disease (STD) in the world with estimates of 7-8 million infections annually in the United States and 180 million globally.Objectives: This study aimed to determine the prevalence and risk factors for T. vaginalis infection in women who attended the Clinic of Obstetrics and Gynecology in Kermanshah, Iran.Patients and Methods: This cross-sectional study was performed on all women aged 15 to 65 years who attended the clinic of obstetrics and gynecology, Imam Reza Hospital, Kermanshah, west of Iran, between September 2011 and July 2012. Vaginal secretion samples were examined by the Dorset culture medium and wet-mount methods. Demographic and personal information were also collected via questionnaires and the data were analyzed using chi-square and Fisher exact tests.Results: A total of 600 women were screened for T. vaginalis infection and this infection was diagnosed in 9 (1.5%) and 13 cases (2.1%) using the wet mount and culture methods, respectively. The age and husband occupation were significantly associated with an increased risk of TRICHOMONIASIS in the infected cases (P<0.05 and P<0.001, respectively); other variables, including the patients' occupation and education level appeared to be positively (but not significantly) correlated with infection (P>0.05).Conclusions: The prevalence of T. vaginalis infection in the study population was low. Diagnosis of TRICHOMONIASIS based on only clinical symptoms is not efficient for treatment decision. Based on our results, we suggest using the culture method on all the suspected cases even if the wet smear is negative.

Background: Erythema nodosum (EN) is the most common form of septal panniculitis resulting from a hypersensitivity reaction in response to numerous antigens or triggers.Case: A 43-year-old female presented with a chief complaint of erythematous painful non-ulcerating nodules on the lower limbs for 18 months. This was preceded by a painful, erythematous rash consisting of a few subcutaneous nodules on both limbs. A dermatological examination of the tibia region revealed multiple tender erythematous and hyperpigmented nodules. A biopsy and serology test were performed to rule out differential diagnoses. Based on the data, the working diagnosis is erythema nodosum caused by TRICHOMONIASIS and vulvovaginal candidiasis. We managed this case with metronidazole 500 mg twice daily for seven days, fluconazole 150 mg as a single dose, and non-steroidal anti-inflammatory drugs. One week after receiving treatment, her pain complaint disappeared, but the hyperpigmented macules still persisted, although they had decreased. One year after treatment, the patient's complaints did not recur.Discussion: EN may be associated with a wide variety of disease processes, and its observation should be followed by finding the underlying etiology. The clinical presentation includes symmetrical, tender, erythematous, warm nodules, and raised plaques usually located on the shins, ankles, and knees. The lesions show spontaneous regression without ulceration, scarring, or atrophy, and recurrent episodes are uncommon. The EN diagnosis is based on clinical presentation and histopathological findings.Conclusion: The management of erythema nodosum involves identifying the etiologic factor and focusing on eliminating exposure or treating the underlying diseases.
