The objective of this study was to compare the uterine health between fertile, sub-fertile alpacas and tuis using transrectal ultrasonography, endometrial cytology and bacterial isolation. A total 10 tuis (young mature females without breeding with average age of 1.5 years) and 20 adult alpacas of the Suri breed were used. In turn, the adult females were divided into two groups of 10 animals each according to their reproductive history: fertile group (parturition every year) and sub-fertile group (1 to 2 years without pregnancy). In all females, the thickness of the cervix and uterine horns was determined by transrectal ultrasonography. On the other hand, endometrial cytology and bacterial isolation were performed from samples obtained by uterine flushing. A Kruskal-Wallis and a Chi-square tests were used to compare ultrasonography and cytology groups. A greater thickness of the cervix and both uterine horns (p˂0,05) was observed in the fertile alpacas with respect to the sub-fertile and tuis. The percentage of PMN in tuis and sub-fertile alpacas was < 2%, while in fertile alpacas the percentage of PMN were: 6 animals with < 2% PMN, 2 animals with 2-5% PMN and two other alpacas with > 5% PMN. The bacteria isolated were: Bacillus lechiniformis and Escherichia coli in the three groups studied, Staphylococcus saprophyticus and Bacillus cereus in tuis and fertile alpacas, Staphylococcus aureus in tuis and sub-fertile, Bacillus spp. and Micrococcus spp. in fertile and sub-fertile alpacas, Bacillus lactic acid, Staphylococcus epidermidis and Citrobacter spp. in fertile alpacas, Enterococcus spp., Bacillus subtilis and Klebsiella spp. in sub-fertile and Enterobacter spp. in tuis. The low percentage of PMN in endometrial cytology in sub-fertile alpacas would indicate the absence of endometritis at the time of the study. However, the lower thickness of the cervix and uterine horns observed in sub-fertile alpacas suggest that it would be necessary to perform uterine biopsies in order to evaluate if there is any association between the thickness of the uterine wall and the presence of degenerative and/or inflammatory changes observed on histopathological examination.

Background: With increasing usage of endoscopic procedures, gastrointestinal polypoidal lesions are commonly encountered specimens. Histopathological examination is crucial as biological behavior is dependent on its pathological nature. Materials and Methods: A retrospective descriptive study performed in Pathology department, Om Hospital and Research Centre from January 2017 to June 2019. The study included lesions received as polyp or polypoidal lesions of gastrointestinal tract for histopathological examination. Data was analysed using SPSS version 17.0. Gender, number and site were analysed using Chi square test to evaluate its association with neoplastic nature. Correlation with age and size was tested with Pearson’s correlation coefficient. Results: Among 150 cases of gastrointestinal tract polypoidal lesions, 58% were seen in male and 42% in female. Hyperplastic polyp and conventional adenoma were the commonest non-neoplastic and neoplastic lesions respectively. The age of patients ranged from 7 to 84 years with a mean age of 50 years. Rectosigmoid region was the commonest site. 134 patients had single and 16 had multiple polypoidal lesions. Most polypoidal lesion had size <1 cm. Gender, age, number and size showed no correlation with neoplastic nature. A significant association was found with site with notably higher number of neoplastic lesions in large intestine. Conclusion: A spectrum of histological types of polypoidal lesions were found in Gastrointestinal tract, most frequently in colorectal region. Hyperplastic polyp and adenomatous polyp were the commonest non-neoplastic and neoplastic lesions respectively. A notably higher number of polypoidal lesions in the large intestine were found to be neoplastic in nature.

Background. Transfusion associated bacterial infection has remained more frequent with a sever risk of morbidity and mortality. This study assessed the bacteriological safety of blood collected for transfusion. Method. A cross-sectional study was conducted at University of Gondar hospital blood bank from December 2011 to June 2012. Bacterial isolation, identification, and antimicrobial susceptibility tests were done as per the standard procedure. Chi-square test and P value were used to assess associations between risk factors and the bacterial isolation rate. Results. Twenty-one (15.33%) blood units were found contaminated with bacteria, and 95.24% contamination was due to external sources. The commonly isolated bacteria were Staphylococcus aureus, Coagulase negative Staphylococci, Escherichia coli, Klebsiella species, Streptococci species, Enterobacter species, and Citrobacter species. All of the bacteria isolated were 100% sensitive to Gentamicin, Chloramphenicol, Amoxicillin, and Doxycycline. Multiple antimicrobial resistances were observed in 66.7% of the isolates. Not using glove by phlebotomist, touching disinfected phlebotomy site and double puncture at the same hand or both hands of a donor were found to be risk factors for bacterial contamination. Conclusion. Bacterial contamination of blood to be transfused is a common problem in the hospital. So attention should be given to activities performed at the blood bank for safe transfusion practices.

In Martinique, Bothrops lanceolatus snakebite, although relatively uncommon (~30 cases/year), may result in serious complications such as systemic thrombosis and local infections. Infections have been hypothesized to be related to bacteria present in the snake’s oral cavity. In this investigation, we isolated, identified, and studied the susceptibility to beta-lactams of bacteria sampled from the oral cavity of twenty-six B. lanceolatus specimens collected from various areas in Martinique. Microbiota from B. lanceolatus oral cavity was polymicrobial. Isolated bacteria belonged to fifteen different taxa; the most frequent being Aeromonas hydrophyla (present in 50% of the samples), Morganella morganii, Klebsiella pneumoniae, Bacillus spp., and Enterococcus spp. Analysis of antibiotic susceptibility revealed that 66.7% of the isolated bacteria were resistant to amoxicillin/clavulanate. In contrast, the majority of isolated bacteria were susceptible to the third-generation cephalosporins (i.e., 73.3% with cefotaxime and 80.0% with ceftazidime). Microbiota from B. lanceolatus oral cavity is polymicrobial with bacteria mostly susceptible to third-generation cephalosporins but rarely to amoxicillin/clavulanate. In conclusion, our findings clearly support that first-line antibiotic therapy in the B. lanceolatus-bitten patients, when there is evidence of infection, should include a third-generation cephalosporin rather than amoxicillin/clavulanate.

The sanitary evaluation of equipment and hands is fundamental to investigate the presence of pathogens in the dairy industry. Then, this study aims to evaluate the sanitization of equipment, workers’ hands, raw and pasteurized milk in goat milk dairies in the Cariri region, state of Paraíba.  Collected 32 samples of four dairies represented by letters A, B, C, and D. The followings contents were analyzed: mesophiles, total and thermotolerant coliforms, Escherichia coli, Staphylococcus aureus, Samonella spp. and Listeria monocytogenes in the reception tank, pasteurization tank, packing machine, package, wall, workers’ hand, and each dairy’s raw and pasteurized milk. After isolation, 84 colonies were confirmed by MALDI TOF. The indicator microorganisms presented variations for the workers’ hands, while A and B stayed within the patterns. For the equipment, only dairy B was within limits. They were out of the standard for mesophiles, total coliforms, and thermotolerant regarding raw and pasteurized milk. The microorganisms, the Enterobacteriaceae family presented a higher frequency, with 77.38%, and within this family, Escherichia coli, Klebsiella spp., and Enterobacter spp. were the most prevalent. Gram-positive corresponded to 22.62%, Bacillus spp., Staphylococcus spp., Enterococcus spp., and Macrococcus caseolyticus. Listeria monocytogenes and Salmonella spp. were not isolated. These demonstrate failures in goat milk processing with pathogenic bacteria in several dairy plants, indicating the need to adjust the product’s quality control.

Background: Liver is not only involved in maintaining homeostasis but also exhibits significant role in metabolism and detoxification of various drugs and toxins. Aim: To explore the hepato-protective role of N-acetylcysteine against methotrexate induced hepato-toxicity. Study design: Randomized controlled trial. Methodology: This study having mice (n=18) was carried out after ethical review committee’s (ERC) approval at Foundation university medical college in collaboration of National institute of health, Islamabad in 2017. Single intraperitoneal injection (20mg/kg) of methotrexate induced hepato-toxicity. Hepatoprotective effect was assessed by oral administration N-acetylcysteine (50mg/kg) alone with methotrexate. The extent of liver damage and effect of protective agents were determined by measuring serum ALT, AST, ALP after 24 hours of respective treatment. Liver samples were taken for histological analysis. One way ANOVA followed by Post Hoc Tukey test was applied for multiple comparisons of biochemical markers between the groups. Histopathological findings were analyzed by Chi Square test. p < 0.05 was considered significant. Results: Significant (p < 0.05) hepatotoxicity was seen with substantial elevation in serum ALT, AST and ALP with methotrexate. N-acetylcysteine attenuated the methotrexate induced hepatotoxicity significantly (p < 0.05). The histopathological examination showed mild steatosis along with focal pleomorphism in the liver of mice that received methotrexate in comparison to group treated with N-acetylcysteine and methotrexate though minimal inflammation was seen. Conclusion: We concluded that N-acetylcysteine ameliorates the methotrexate induced hepatotoxicity on when used concomitantly. Keywords: Hepatotoxicity, N-acetylcysteine and Methotrexate

Hospital Wards

T hree clinical wards in the same hospital, High Dependency (HDU), Care of the Elderly (CE) and Acute Psychiatry (AP), were screened for environmental organisms. The screening programme ran for four weeks and targeted comparable sites from all three units. Floor areas were similar, as were staffing levels, cleaning schedules, infection control policies and patient numbers. Organisms such as coagulase-negative staphylococci, Bacillus spp., coliforms, oxidase-positive Gram-negative bacilli, Clostridium difficile, enterococci, various fungi and Staphylococcus aureus were isolated. Staphylococci and Gram-negative bacilli were tested against clinically appropriate antibiotics. There was little variation in diversity or density of organisms from any of the wards, except for significant differences in antibiotic susceptibilities of the organisms (P<0.0001 HDU v AP, P=0.0057 CE v AP and P=0.0365 HDU v CE). From HDU, 49% (of 43) isolates were resistant to four or more antibiotics and from CE, 37% (of 54) isolates were resistant to four or more. From AP, just 2% (of 52) were resistant to four or more antibiotics. 9% HDU organisms were fully susceptible, as compared with 20% of those from CE and 27% from AP. Antibiotic data (in Defined Daily Doses (g)/100 bed-days) showed that HDU consumed over 12 times more antibiotics than CE, which in turn consumed twice as much as AP; these were mostly intravenous broad-spectrum agents for HDU, as opposed to oral preparations for the other two wards (Chi-square for each ward for linear trends by level of antibiotic intake were all P<0.0001). It was concluded that the only significant difference between environmental bacteria from wards of varying specialities in this hospital is their resistance to antibiotics. Heavy use of antibiotics in a hospital unit, as demonstrated by antibiotic consumption data, may be associated with increased antibiotic resistance in environmental organisms originating from that unit.

Two Phases

In Holstein cows, the diameter of the dominant follicle (DF) at the time of follicle deviation is 8.5 mm and the subordinate follicle (SF) is 7.2 mm (Ginther et al. 1996 Biol. Reprod. 55, 1187–1194). However, follicular responsiveness to an ovulatory treatment occurs only with 10.0-mm-diameter follicles (Sartori et al. 2001 Biol. Reprod. 65, 1403–1409). The current study tested the hypothesis that, in Bos indicus (Nelore and crossbred Nelore � Gir) females, the follicular diameters at the time of deviation and ovulation responsiveness are smaller than those in Holstein cows. The experiment was performed in two phases. In the first phase, 12 Nelore heifers were previously synchronized with a protocol using progestagen and estradiol benzoate. After implant removal, all heifers were evaluated by transrectal ultrasonography (Aloka SSD-500, Tokyo, Japan) every 12 h until Day 5 of the estrous cycle (Day 0 = Day of the ovulation) to assess the time of ovulation, the time of follicle deviation, and the follicular diameter at the deviation. In the second phase, 29 Bos indicus heifers (Nelore and crossbred Nelore � Gir) were previously synchronized with the same protocol as cited above. After the ovulations (Day 0), the follicles were evaluated by transrectal ultrasonography every 24 h, until they reached the diameter of 7.0–8.4 mm (n = 9); 8.5–10.0 mm (n = 10); and &gt;10.0 mm (n = 10). In order to assess the ovulatory capacity, all animals were treated with 25 mg of LH (Lutropin-V�; Bioniche Animal Health, Inc., Belleville, Ontario, Canada) at these follicle diameter ranges. After the LH treatment, all animals were monitored by ultrasonography every 12 h for 48 h. ANOVA, Bartlett, and chi-square tests were used in the statistical analyses. In the first phase, the diameters of the DF and SF at the time of follicular deviation (61.9 � 4.9 h after ovulation) were 6.2 � 0.2 and 5.8 � 0.2 mm, respectively. In the second phase, the the average follicular diameters at the time of LH administration in the groups 7.0–8.4 mm, 8.5–10.0 mm, and &gt;10.0 mm were 7.6a � 0.1 mm, 9.6b � 0.1 mm, and 10.9c � 0.2 mm; and their ovulation rates were 33.3%a (3/9), 80.0%b (8/10), and 90.0%b (9/10), respectively (P &lt; 0.05). The interval from LH treatment to ovulation was 38.0 � 4.0 h, 31.5 � 2.7 h, and 30.0 � 2.0 h, respectively (P &gt; 0.05). In conclusion, in Bos indicus heifers, follicle deviation occurred with smaller diameters than previously reported in Bos taurus breeds. In addition, Bos indicus heifers are able to ovulate in response to 25 mg of LH with smaller diameters compared to those of Bos taurus breeds. Moreover, in Bos indicus heifers, ovulatory capacity is acquired by follicles as small as 7.0–8.4 mm, but this responsiveness significantly increases after follicles reach 8.5–10.0 mm.

Enterovirus-induced myocardial injury can lead to severe heart failure. To date, little is known about the early innate stress response that contributes to host defense in the heart. Toll-like receptor 3 (TLR3) is important in the initiation of the innate antiviral response. We investigated the involvement of TLR3, which recognizes viral double-stranded RNA, on encephalomyocarditis virus (EMCV) infection. To examine the contribution of TLR3 in protection from EMCV infection, we infected mice deficient in TLR3 with 50 plaque-forming units of EMCV. TLR3-deficient (TLR3−/−) mice were more susceptible to EMCV infection and had a significantly higher viral load in the heart compared with TLR3+/+ mice. Histopathological examination showed that the inflammatory changes of the myocardium were less marked in TLR3−/− than in TLR3+/+mice. TLR3−/− mice had impaired proinflammatory cytokine and chemokine expression in the heart following EMCV infection. However, the expression of interferon-β was not impaired in EMCV-infected TLR3−/− mice. EMCV infection leads to a TLR3-dependent innate stress response, which is involved in mediating protection against virus-induced myocardial injury.

Introduction: Carcinosarcoma is a rare gynecological malignancy and it usually follows an aggressive clinical course. Rarely, it can be confined to an endometrial polyp or be synchronous with another gynecological malignancy. Herein, we report a rare case of synchronous carcinosarcoma confined to an endometrial polyp and endometrioid endometrial adenocarcinoma arising from a distinct uterine wall site. Case presentation: A 57-year-old female patient presented with heavy vaginal bleeding. She underwent hysterectomy with bilateral salpingo-oophorectomy for endometrioid endometrial adenocarcinoma that was diagnosed preoperatively through dilation and curettage. Full histopathological examination of the uterine specimen revealed carcinosarcoma confined to a 4 cm endometrial polyp in addition to a stage IA endometrioid endometrial adenocarcinoma which arose from a distinct uterine wall. Conclusion: Having an endometrioid endometrial cancer diagnosis preoperatively through dilation and curettage and at examination of the frozen section specimen following surgical resection should not preclude the standard full histopathological examination of the uterine specimen, since this could reveal an additional uterine malignancy, such as carcinosarcoma. Such a finding would alter the post-operative management, prognosis, and outcome even if it is confined to an endometrial polyp.

ABSTRACT We compared the effects of DQ-113, a new quinolone, to those of vancomycin (VCM) and teicoplanin (TEIC) in murine models of hematogenous pulmonary infections caused by methicillin-resistant Staphylococcus aureus (MRSA) and VCM-insensitive S. aureus (VISA). The MICs of DQ-113, VCM, and TEIC for MRSA were 0.125, 1.0, and 0.5μ g/ml, respectively; and those for VISA were 0.25, 8.0, and 8.0μ g/ml, respectively. Treatment with DQ-113 resulted in a significant decrease in the number of viable bacteria in the lungs of the mice used in the MRSA infection model (counts in mice treated with DQ-113, VCM, and TEIC and control mice, 6.33 ± 0.22, 7.99± 0.14, 7.36 ± 0.20, and 8.47 ± 0.22 log10 CFU/lung [mean ± standard error of the mean], respectively [P < 0.01 for the group treated with DQ-113 compared with the group treated with VCM or TEIC or the untreated group]). Mice infected with VISA were pretreated with cyclophosphamide, and the survival rate was recorded daily for 10 days. At the end of this period, 90% of the DQ-113-treated mice were still alive, whereas only 45 to 55% of the mice in the other three groups were still alive (P < 0.05 for the group treated with DQ-113 compared with the group treated with VCM or TEIC or the untreated group]). DQ-113 also significantly (P < 0.05) reduced the number of viable bacteria in the lungs compared with those in the lungs of the other three groups (counts in mice treated with DQ-113, VCM, and TEIC and control mice, 5.76 ± 0.39, 7.33 ± 0.07, 6.90± 0.21, and 7.44 ± 0.17 log10 CFU/lung, respectively). Histopathological examination revealed milder inflammatory changes in DQ-113-treated mice than in the mice in the other groups. Of the antibiotics analyzed, the parameters of area under the concentration-time from 0 to 6 h (AUC0-6)/MIC and the time that the AUC0-6 exceeded the MIC were the highest for DQ-113. Our results suggest that DQ-113 is potent and effective for the treatment of hematogenous pulmonary infections caused by MRSA and VISA strains.
