Effect of male age in Caspian brown trout, Salmo trutta broodstock on reproductive performance

In this study, three different age groups of male broodstocks (4, 5 and 6 years respectively) were used to fertilize eggs obtained from nine females. The results showed that 6 year old males had maximum body weight (1766 g), total length (56.3 cm) and sperm volume (31.83 ml). Results did not show significant difference in spermatocrit and spermatozoa concentration among age groups (p>0.05). Our study showed maximum fertilization rate (98.5 %), survival rate until eyes pigmentation (91.17 %), hatching rate (94.5 %) and survival rate until absorption of yolk sack (97.16 %) for 4 years treatment group. Such positive relationships were detected between sperm production characteristics (spermatozoa concentration, spermatocrit and sperm volume) and fertilization parameters. Based on our results, it can be concluded that 4 year old males have high efficiency leading to fertilization success

Peripheral primitive neuroectodermal tumor associated with paraneoplastic Cushing's syndrome: The rare case

Introduction: Primitive neuroectodermal tumors (PNET) form a group of tumors defined by their appearance that are thought to develop from primitive (undifferentiated) nerve cells in the brain. They are rare tumors and their incidence is not well defined. Case presentation: An 18-month-old male presenting with typical Cushingoid appearance (moon face, central obesity, hirsutism and growth arrest) was admitted for evaluation of endocrine problems. Subsequent laboratory studies revealed markedly elevated adrenocorticotropic (ACTH) and cortisol levels, as well as a hypokalemic metabolic alkalosis, these data are consistent with the diagnosis of Cushing's disease. He was treated with metyrapone to control hypercortisolemia. One month and a half later, a mass was detected in the abdomen by ultrasonography. An abdominal Computed tomography confirmed a large heterogeneous retroperitoneal mass with a significant amount of extension into surrounding structures which was removed by laparoscopic abdominal surgery. The patient's symptoms completely resolved and the ACTH and cortisol levels were also greatly reduced. Histologically, the tumor tissue consistent with the diagnosis of the retroperitoneal primitive neuroectodermal tumor which was confirmed immunohistochemically. This case demonstrates the successful diagnosis and treatment of a rare neoplasm. Conclusion: This is the first rare case with ectopic ACTH syndrome caused by the peripheral primitive neuroectodermal tumor. © 201

The effect of grandmultiparity on pregnancy related complications: The Aga Khan University experience

Background: Grandmultiparity has been associated with complications for both mother and the fetus.Objective: To evaluate if grandmultiparity is a risk factor in the presence of adequate antenatal care.Setting: A tertiary care teaching hospital.Methods: It was a retrospective study conducted in the department of Obstetrics & Gynecology at The Aga Khan University Hospital in Karachi. During this period 9253 women were delivered, out of these 143 booked grandmultiparas (GMP) served as cases. The outcome of these women was compared with 430 non-grandmultiparas (NGMP). Logistic regression model was used to adjust for potential confounders.Results: Grandmultiparas had almost three times increased risk of having postpartum hemorrhage compared to NGMP group. Similarly, there were significantly low five-minute apgars in the GMPs compared to the NGMP group. Although the neonatal intensive care admissions were three times more in the GMPs but this did not reach statistical significance due to small number of cases in both groups.Conclusion: Our study indicates that grandmultiparity is a risk factor for pregnancy in this part of the world, even in the presence of reasonable antenatal care. This may be explained on the basis of the increased age of these women. Finally, we also recommend that an age-matched study needs to be undertaken in order to determine if age is an important determinant for risk factors in grandmultiparas

Appendix epidermoid cyst: Presenting as an acute appendicitis

We report a rare case of a cystic mass in an appendix in a patient who presented nausea, vomiting, and sharp pain in lower right abdomen and mimicking acute appendicitis. Although this entity is very rare, careful physical observation, imaging, and pathology can be helpful to make an accurate diagnosis. © 2018 The Authors.

Isolation of rapid growing mycobacteria from soil and water in Iran

A total of 350 soil samples were collected from different part of Uremia city and suburbs. We used 3% sodium lauryl sulfate and 1% NaOH for decontamination of soil samples. Of 350 samples, mycobacteria were isolated from 65 (18.3%) specimens. Mycobacterium fortuitum with 18(5.14) strains yielded the highest frequency of isolation. The other isolates were: Mycobacterium peregrinum 11(3.14%), Mycobacterium flvescens 10 (2.85%), Mycobacterium chelonae 6 (1.71%), Mycobacterium mucogenicum 6(1.71%), Mycobacterium thermoresistable 4(1.14%), Mycobacterium abscessus 3 (0.85%), Mycobacterium neoaurum 2(0.57%), Mycobacterium smegmatis 2 (0.57%) and M. fortuitum third biovalant complex 3 (0.85%). The mean pH of soil was 7.89 ± 0.379 (max 8.5, min 7.5). Our data showed an abundant occurrence of mycobacteria in low pH (P value = 0001). We also collected 120 water samples from rivers, brooks and drinking water. Water samples decontaminated were by adding cetylpyridinium chloride (CPC) to give final concentration of 0.05%. Mycobacteria isolated from 12 water samples. The predominant isolated species were M. fortuitum and Mycobacterium cheloni. The majorityisolates were from brooks and surface waters

Risk behaviours associated with urethritis in prison inmates, Sindh

Objective: To identify sexual risk behaviours associated with lifetime risk of urethritis in prison inmates.Design: A cross-sectional study using a pre-designed questionnaire.SETTING: Fourteen prisons throughout the Sindh Province, Pakistan.SUBJECTS: Three thousand three hundred ninety-five prison inmates incarcerated during July, 1994.MAIN OUTCOME MEASURE: Lifetime risk of urethritis occurrence (whether or not the subject was ever affected with urethritis up to his present age)Results: Lifetime risk of urethritis occurrence in the study population was 20.8% (706/3395). The final multivariate logistic regression model indicated that risk behaviours associated with lifetime risk of urethritis in this population were \u27sexual intercourse with a female\u27 (adjusted OR = 2.18; 95% CI 1.60, 2.95), \u27multiple female sexual partners\u27 (adjusted OR = 1.67; 95% CI 1.28, 2.18) and \u27sexual intercourse with man\u27 (adjusted OR = 2.75; 95% CI 2.29, 3.31).CONCLUSION: The prevalence of urethritis in this population was very high. High prevalence of various risky sexual behaviours among inmates indicates, their unawareness as to what precautions they might take to avoid risk of acquiring STDs including HIV. The study subjects meet the characteristics of a core group of STDs transmitters and provides short window of opportunity for STD/HIV control programs to intervene, while they are in detention to reduce the risk not only for this group but also for general population

Screening of von willebrand disease in iranian women with menorrhagia

Results: Mean age of our patients was 32.5 ± 10.6 years. The level of von Willebrand factor in 22.5 and von Willebrand activity in 19.6 of patients was abnormal. The prevalence of vWD among patients with menorrhagia was 24. Conclusions: The high prevalence of vWD among our patients was the same as other previous reports, suggesting low awareness about this disease and under diagnosis of mild cases. Background: Menorrhagia is a common health problem in women, particularly those with bleeding disorders. Little is known about the course of menorrhagia or other bleeding symptoms in women with the most common congenital bleeding disorder, von Willebrand disease (vWD). Objectives: The aim of this study was to estimate the prevalence of vWD in women with diagnosed menorrhagia. Materials and Methods: In this cross-sectional study, a total of 460 consecutive patients, presenting menorrhagia, were analyzed. The initial screening and confirmation tests for the diagnosis of vWD included determination of prothrombin time (PT), partial thromboplastin time (PTT), bleeding time (BT), fibrinogen, factor VIII, vWF antigen, and vWF activity. A questionnaire was filled for every patient. The data were then analyzed using the SPSS software. © 2015, Iranian Red Crescent Medical Journal

Multivariate analysis of risk factors associated with genital ulcer disease among incarcerated males in Sindh

Objective: To evaluate the potential risk behaviors associated with the lifetime risk of self reported genital ulcer disease (GUD) among prison inmates.SETTING: Prison inmates from 14 prisons of Sindh Province.Methods: A cross-sectional study was conducted on 3395 prison inmates during July to December, 1994. A questionnaire was used to assess the lifetime risk of self-reported GUD (whether or not the subject was ever affected with GUD up to present age) and to investigate demographic markers and risk behaviors for their possible association with lifetime risk of GUD using logistic regression analysis.Results: The reported lifetime risk of GUD in the study sample was 11.4% (386/3395). In final multivariate logistic regression model the sexual behaviors which were independently associated with GUD were having sexual intercourse with female (adjusted OR = 1.7; 95% CI: 1.3-2.3, P = 0.0002), sexual intercourse with a prostitute (adjusted OR = 1.5; 95% CI: 1.2-2.0, P = 0.0008), sexual intercourse with man (adjusted OR = 2.2; 95% CI: 1.7-2.7, P = \u3c 0.001) and sexual intercourse with man during current incarceration (adjusted OR = 1.9; 95% CI: 1.2-2.9, P = 0.0071).CONCLUSION: Health education needs to re-enforce monogamous relationship for high risk groups such as in our study. Although infrequent condom use was not a risk factor for GUD in this study, yet based on the results of previous studies, promotion of condom use should be the component of health education program

Prevalence of Chlamydia trachomatis infections in symptomatic women by polymerase chain reaction (PCR) immunofluorescence and Giemsa stain

Chlamydia trachomatis is a ubiquitous human pathogen that is responsible for the most prevalent bacterial sexually transmitted disease worldwide. Studies show that polymerase chain reaction (PCR) is more sensitive than cellular culture for detection of C. trachomatis infections. The aim of this study is to compare different laboratory methods, including Giemsa staining, direct immunofluorescence assay (DFA) and PCR for detection of C. trachomatis in women with urethral symptoms. In this study, 130 women with urethral symptoms admitted in the gynecology clinic, were used and specimens were obtained with endocervical swab for Giemsa staining, DFA and PCR. All the cases underwent these three techniques. Demographic data and the medical history of patients were obtained by direct interview; however, the mean age of cases was 33.8±9.06. Clinical symptoms included abnormal vaginal discharge in 101 cases (77.7%), spotting in 14 cases (10.8%), dysmenorrheal in 7 cases (5.4%), irritation in 6 cases (4.6%) and dysuria in 2 cases (1.5%). In DFA technique, 5 cases (3.8%) were positive and 3 (2.3%) were suspicious, while in the PCR technique, 6 cases (4.6%) were positive for C. trachomatis. However, 3 suspicious cases with DFA were negative in PCR. There was no positive case for C. trachomatis in Giemsa staining. In conclusion, C. trachomatis was not frequent in this study and it can be concluded that this infection was not a major hygienic problem in the same populations that were previously studied. Consequently, the causes that necessitate monogamy could be related to religious causes. Frequency of Chlamydia detection of DFA and PCR was same in the two groups. Nonetheless, Giemsa staining is not a reliable method for evaluating C. trachomatis.Key words: Chlamydia trachomatis, polymerase chain reaction (PCR), direct immunofluorescence assay (DFA)
