Durable complete remission with aromatase inhibitor therapy in a patient with metastatic uterine carcinosarcoma with poor performance status and coagulation disorders: a case report. J Med Case Rep 2017; 11:115. [PMID: 28424084 PMCID: PMC5397750 DOI: 10.1186/s13256-017-1262-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2016] [Accepted: 03/06/2017] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Chemotherapy is considered the most appropriate treatment for metastatic uterine sarcoma, despite its limited efficacy. No other treatment has been conclusively proved to be a real alternative, but some reports suggest that anti-hormonal therapy could be active in a small subset of patients. We report the case of a patient with metastatic uterine carcinosarcoma with positive hormonal receptors and a complete pathological response. CASE PRESENTATION A 54-year-old white woman presented to our emergency room with hypovolemic shock and serious vaginal bleeding. After stabilization, she was diagnosed as having a locally advanced uterine carcinosarcoma with lymph nodes and bone metastatic disease. In order to control the bleeding, palliative radiotherapy was administered. Based on the fact that positive hormone receptors were found in the biopsy, non-steroidal aromatase inhibitor therapy with letrozole was started. In the following weeks, her general status improved and restaging imaging tests demonstrated a partial response of the primary tumor. Ten months after initiating aromatase inhibitor therapy, she underwent a radical hysterectomy and the pathological report showed a complete response. After completing 5 years of treatment, aromatase inhibitor therapy was stopped. She currently continues free of disease, without further therapy, and maintains a normal and active life. CONCLUSIONS This case shows that patients with uterine carcinosarcoma and positive hormone receptors may benefit from aromatase inhibitor therapy. A multidisciplinary strategy that includes local therapies such as radiation and/or surgery should be considered the mainstay of treatment. Systemic therapies such as hormone inhibitors should be taken into consideration and deserve further clinical research in the era of precision medicine.

Clearance of Tritrichomonas foetus in experimentally infected heifers protected with vaccines based on killed-T. foetus with different adjuvants. Vaccine 2017; 35:1341-1346. [PMID: 28185741 DOI: 10.1016/j.vaccine.2016.12.030] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2016] [Revised: 12/13/2016] [Accepted: 12/14/2016] [Indexed: 11/15/2022]
Abstract
Tritrichomonas foetus is a flagellated protozoan that causes a sexually transmitted disease in cattle. Trichomonosis is characterized by early abortions, subfertility and a significant decrease in productivity. Vaccine preparations containing whole T. foetus can reduce the time of residence of the pathogen in the host cervix after experimental infection. Here, T. foetus vaccines prepared with different adjuvants were tested, in parallel with a commercial vaccine, for their efficacy to clear the infection. The median time for clearance of infection was 69days in non-immunized animals, 55days in animals treated with aluminum hydroxide, 41days with oil-in-water or saponin based vaccines or with a commercial vaccine and 27days in animals treated with saponin plus aluminum hydroxide. A slight increase in the risk of T. foetus clearance from the genital tract was found with the saponin based vaccine (hazard ratio, 2.52; 95% confidence interval, 1.03-6.17) or the commercial vaccine (hazard ratio, 2.61; 95% confidence interval, 1.07-6.38). A significant increase in the risk of T. foetus clearance was found with the combination of saponin plus aluminum hydroxide based vaccine (hazard ratio, 5.12; 95% confidence interval, 2.04-12.83).

Abstract
Bovine genital campylobacteriosis is a reproductive disease that affects cattle production. It is caused by Campylobacter fetus subspecies, C. fetus fetus (Cff) and C. fetus venerealis (Cfv). The aim of this study was to identify the presence of C. fetus in genital fluids by bacteriological culture and direct immunofluorescence (DIF) and to compare the results. Two groups of 6 heifers and 5 bulls, one infected with Cff (Cff group) and the other with Cfv (Cfv group) were formed. Two heifers and 2 bulls, all of them uninfected, made up the control group. Samples of cervicovaginal mucus and preputial fluid were processed by culture and DIF. In the Cff group, 100% of the heifers and 80% of the bulls were infected, while in the Cfv group, 50% of the heifers and 60% of the bulls were infected. The degree of agreement (Kappa values) from benchmarking diagnostic techniques were 0.57 for heifers in the Cff group and 0.52 for heifers in the Cfv group, whereas the values for bulls were 0.17 and 0.27, respectively. Heifers yielded more positive results in the DIF assay than in the culture, exhibiting 5.6% increase in the Cff group and 7.4% in the Cfv group. The lowest percentage of positive results for DIF in bulls, 40% less for the Cff group and 5.2% for the Cfv group, could be due to improper sampling. Kappa values showed moderate agreement for the heifers and low for the bulls.

Abstract
OBJECTIVE The most common treatment in recurrent malignant ascites is generally temporary peritoneal drainage. We present our experience in placing permanent tunneled catheters in a series of patients and analyze the safety and efficacy of the treatment. MATERIAL AND METHODS We used total aseptic measures in the interventional ultrasonography suite to place permanent tunneled catheters in 10 patients under ultrasonographic guidance and local anesthesia. RESULTS The catheters remained patent for a median of 52 days in the nine patients who died. In one of these, the catheter was withdrawn while still patent due to generalized sepsis. At the end of the study, one patient still had a permeable catheter 124 days after placement. CONCLUSION Although the low number of patients in our series precludes generalizations, tunneled peritoneal catheters seem to be a safe and effective minimally invasive treatment for malignant ascites in terminal oncologic patients. This approach facilitates the draining of the ascites at home, obviating the need for repeated hospital visits and punctures and the risks involved therein. Nevertheless, further experience and prospective randomized trials are necessary.

Meissner effect in superconducting microtraps. PHYSICAL REVIEW LETTERS 2008; 101:183006.

Abstract
We report on the realization and characterization of a magnetic microtrap for ultracold atoms near a straight superconducting Nb wire with circular cross section. The trapped atoms are used to probe the magnetic field outside the superconducting wire. The Meissner effect shortens the distance between the trap and the wire, reduces the radial magnetic-field gradients, and lowers the trap depth. Measurements of the trap position reveal a complete exclusion of the magnetic field from the superconducting wire for temperatures lower than 6 K. As the temperature is further increased, the magnetic field partially penetrates the superconducting wire; hence the microtrap position is shifted towards the position expected for a normal-conducting wire.

Abstract
Pulmonary nodules are a common finding in routine chest studies. Although there are no pathognomic clinical or radiological signs that enable the exact nature of a pulmonary nodule to be determined, the clinical context and the appropriate characterization of the pulmonary nodule make it possible to reach the correct diagnosis in most cases. This article discusses the most important aspects involved in the use of multislice computed tomography in the noninvasive detection and characterization of pulmonary nodules.

Abstract
BACKGROUND Autologous breast reconstruction with abdominal tissue is one of the best options after mastectomy. Reconstruction with deep inferior epigastric perforator (DIEAP) flaps requires a precise location and preoperative evaluation of perforating vessels. The objective of this report is to demonstrate the usefulness of multislice-CT (MSCT) angiography for preoperative planning in patients undergoing DIEAP flap reconstruction. METHODS Six consecutive women were considered for breast reconstruction with DIEAP flaps after previous mastectomy for breast cancer. Preoperative MSCT angiography was performed to localise the arterial perforators. Axial images, multiplanar reconstructions (MPR) and 3D volume-rendered images were analysed. Findings were correlated with surgery. Initial experience and imaging findings will be described. RESULTS Accurate identification of the main perforators was achieved in all six patients with a very satisfactory concordance between MSCT angiography and surgical findings. No unreported vessels were found. Location, course, anatomical variations and relations of the superficial inferior epigastric artery were reported. The very small perforators, were equally evaluated and described. CONCLUSIONS Preoperative evaluation of perforator arteries with MSCT angiography is feasible in patients undergoing breast reconstruction. This technique provides a noninvasive global approach of the vascular anatomy and the entire anterior abdominal wall. However, more patients need to be evaluated in order to clarify the potential aspects pointed in this report.

Abstract
Vaccines against both bovine venereal campylobacteriosis and trichomonosis were tested. Heifers were assigned to three groups. Groups 1 (n = 21 heifers) and group 2 (n = 20) received a commercial or experimental vaccine, respectively, containing both Campylobacter fetus and Tritrichomonas foetus antigens. Group 3 (n = 21) received adjuvant alone. Preparations were injected SQ in groups 1 and 3 at days -60 and -30 (day 0 was considered the first day of a 90-day breeding period), and in group 2 SQ at days -30 and +11 and into the vaginal submucosa at day -9. Heifers were exposed to two pathogen-infected bulls for 90 days (from day 0 to day +90); furthermore, half of the heifers in each group were challenged at day +39 by an intravaginal instillation of C. fetus venerealis and T. foetus. Pregnancy diagnosis, vaginal culture, and determination of systemic IgG for both organisms were performed. Compared to controls, vaccinated heifers resisted or quickly cleared both pathogens, had a higher pregnancy rate and a higher systemic immune response during and after the breeding period. Overall, the experimental vaccine was superior to the commercial vaccine (groups 2 and 1, respectively). In conclusion, an experimental vaccine containing both C. fetus and T. foetus antigens, given both SQ and intravaginal immediately before breeding and early in the breeding season, yielded superior protection for heifers exposed to bulls harboring C. fetus and T. foetus.

Abstract
Since the introduction of last generation multislice MSCT systems and the development of simultaneous electrocardiographic-tracing image acquisition and retrospective reconstruction techniques into clinical routine, cardiac MSCT has been considered a very useful non-invasive technique for the study of cardiac pathology in the daily clinical practice. One of the main clinical applications of this diagnostic technique is the evaluation of the coronary arteries including detection and quantification of coronary calcium, multislice CT coronary angiography (anatomy, anatomical variants and anomalies of the origin and course), the angiographic evaluation of the patency of aortocoronary by-pass grafts and coronary stents, and plaque characterization. The new reconstruction and postprocessing programs allow to obtain, in addition, parameters of myocardial morphology and contraction and cardiac function. Other clinical applications include the characterization of cardiac masses and the evaluation of the pericardium.

Abstract
Experimental infection of the reproductive tracts of heifers and bulls with Tetratrichomonas sp. isolated from preputial smegma of virgin bulls was attempted. Nine heifers and four bulls were challenged by inoculation of 7 x 10(6) Tetratrichomonas sp. into the vaginal lumen and preputial cavity, respectively. Vaginal mucus and preputial smegma samples were collected and cultured for Tetratrichomonas sp. Heifers were slaughtered in groups of three at 2, 9 and 21 days after inoculation. Two heifers and two bulls infected with Tritrichomonas foetus and two uninfected heifers were used as controls for the model infection. Tetratrichomonas sp. were only isolated in vaginal mucus of 7/9 inoculated heifers at 6h post-inoculation, and genital secretions taken at slaughter time from vagina, uterus and oviduct were cultural negative. Bulls challenged with Tetratrichomonas sp. remained cultural negative. Since Tetratrichomonas sp. survived only a few hours in the female genitalia and did not survive in the male genitalia after experimental challenge, Tetratrichomonas sp. did not colonize the genital tract. These were likely trichomonads from the digestive tract. Collection of clean samples without fecal contamination from the reproductive tract is proposed as a measure to avoid Tetratrichomonas sp. transitory genital infection.

Abstract
Efficacy of two commercial vaccines containing Campylobacter fetus subspecies on heifers naturally challenged by service with an infected bull was tested. Sixteen heifers were vaccinated parentally two times with 3 weeks as interval, eight with commercial vaccine A and the other eight with commercial vaccine B. Eight other heifers were used as unvaccinated controls. Forty days after the first vaccine dose, the heifers were served by an infected bull during 60 days. Measure of systemic immune response and identification of the microorganism from genital secretions by culture and immunofluorescent antibody test (IFAT) were done. Vaccinated and control heifers had a poor reproductive performance (pregnancy rates were 2/8, 3/8 and 0/8 in groups A, B and C, respectively) and were infected by both methods during breeding time and after it. Moreover, one heifer in the groups B and C remained infected until 300 days post-breeding time. Neither vaccinated nor control heifers had an important increment of systemic antibody level. Only, they had a slight increment of antibody level after the breeding period and it may be because of natural stimulus by the infected bull during the copula. Culture and IFAT yielded high correlation on identification of C. fetus subspecies.

Abstract
The performance of a whole-cell vaccine and the other vaccine with cellular membranes of Tritrichomonas foetus applied to heifers naturally challenged by mating with an infected bull was determined. Forty heifers were divided into three groups: a control group (n=16) without immunizing, another group (n=12) immunized with whole cells (10(8)/dose) and a third group (n=12) immunized with cellular membranes (300 micro g of membranes/dose protein). The females were subcutaneously vaccinated at 3-week on two occasions and received a third intravaginal booster dose. After 3 weeks of the last vaccinal doses, the heifers were served by a T. foetus infected bull over 90-day period. The mean duration of infection for membrane-vaccinated heifers was 60 days +/-25, compared with 63 days +/-35.8 of infection for whole-cell-vaccinated heifers and 79 days +/-41.3 for control heifers. Calving rates were 6/12 for membrane-vaccinated heifers, 3/12 for whole-cell-vaccinated animals, and 2/16 for control animals. Fetal mortality rates were 3/12 for membrane-vaccinated animals, 4/12 for those vaccinated with whole cells and 10/16 for control animals. These reproductive parameters were significantly different (P<0.05) between heifers vaccinated with membranes and control heifers. The hemolytic test and enzyme-linked immunoabsorbent assay (ELISA) with T. foetus antigen showed that serum immunoglobulins peaked before and during the breeding period. The heifers vaccinated with membranes developed an important response during the critical period of fetal loss, second and third month of the breeding time, and another month after the same period. The ELISA method was more sensitive and more reliable than the hemolytic test for the evaluation of the systemic immune response in females infected and/or vaccinated with T. foetus.

Abstract
The purpose of the present work was to study the epidemiology of Neospora caninum in beef and dairy herds in the Humid Pampas of Argentina. The seroprevalence of N. caninum was evaluated in 2414 serum samples of cows from beef and dairy farms. An indirect fluorescent antibody test (IFAT) was used to determine specific antibodies. The sera was screened at a dilution >or=1:200 and >or=1:600 in cows with reproductive disease antecedents and without them, respectively. Cows without history of reproductive diseases from nine beef and fifteen dairy farms were grouped according to the percentage (> or <or= to 50%) of seropositive dogs. Additionally, the seroprevalence in beef and dairy cattle cohabiting in the same farm with these dogs was compared. Microscopic studies were performed in 188 aborted fetuses and/or their placentas. Formalin-fixed fetal tissues with microscopic lesions compatible with N. caninum were processed by immunohistochemistry (IHC). The seroprevalence in cows without reproductive diseases was 4.7% (19/400) for beef cattle and 16.6% (174/1048) for dairy cattle. The seroprevalence of N. caninum in dairy cattle was higher (P<0.05) in farms grouped according to the percentage (> or <or= to 50%) of seropositive dogs. The analysis of 966 serum samples from aborted cows, demonstrated positive 18.9% (41/216) and 43.1% (323/750) from beef and dairy herds, respectively. Microscopic lesions compatible with N. caninum were observed in 43 of 188 (22.8%) fetuses and/or placentas evaluated. The protozoan was identified in 29 of 43 (67.4%) aborted specimens, being the largest number of positive results in dairy fetuses. The results obtained demonstrate a high association between neosporosis and dairy herds, however, our data also reveals that N. caninum is an important risk factor for reproductive losses in the extensively farmed beef cattle in the Humid Pampas of Argentina.

Abstract
Nine heifers were intravaginally challenged with 9.3x10(6) Tritrichomonas suis reference strains. Vaginal mucus and serum samples were collected weekly 4 weeks post-inoculation. Vaginal mucus was cultured for T. suis and sera was tested by ELISA against whole cell antigens for T. suis and Tritrichomonas foetus. All vaginal mucus cultures were T. suis-negative during the experiment. ELISA values for both antigens were similar and differences were not significant (P>0.05). Positive control serum samples from one heifer vaccinated against T. foetus showed anti-T. suis ELISA values. We concluded that T. suis intravaginal inoculation induced a low level of serum immune response in heifers measured by ELISA and both protozoa probably share a common antigen. However, under the experimental conditions of this trial, colonization of the heifers' genital tract was not possible in any of the nine animals.

Abstract
AIMS The effects on fetal growth of hyperlipidaemia in pregnancy are not well understood at present. In this study the different lipid fractions in normal pregnancies and pregnancies complicated by intrauterine growth retardation (IUGR) were determined and related to changes in plasma and serum viscosity. METHODS Two groups of pregnant women were studied. Group 1 consisted of 35 healthy pregnant women aged between 21 and 38 years with no previous pathology and a normal pregnancy to term. Group 1 patients were studied at four periods defined at the start of the study: (1) < or = 17 weeks; (2) 18-24 weeks; (3) 25-32 weeks, (4) > or = 33 weeks. Group 2 consisted of 24 pregnant women aged between 16 and 34 years with ultrasound diagnosed IUGR confirmed after birth. Plasma lipids and plasma and serum viscosity were measured. RESULTS Plasma triglycerides, low density lipoprotein cholesterol, and total cholesterol increased progressively throughout pregnancy, with significantly higher values after week 25. Apolipoprotein A (ApoA) and triglyceride concentrations were significantly lower in the IUGR group than in the normal group. The HDL/ApoA ratio was greater in the IUGR group than in the control group, as was the ApoB/ApoA ratio. There were no differences in the other lipids. Plasma and serum viscosity was higher in the IUGR group than in the normal group. CONCLUSIONS Haemorheological modifications in the IUGR group are partly secondary to changes in high density lipoprotein metabolism and the competitive inhibition of fibrinolysis by ApoB, which is increased in pregnancies with IUGR. Changes in ApoA, and more specifically in the ApoB/ApoA ratio, could be good markers for the early detection of IUGR.

Abstract
Serum lipids, lipoproteins and apolipoproteins A and B were measured in 101 epileptic patients receiving chronic treatment with valproic acid, carbamazepine or phenobarbital and in 75 age- and sex-matched control subjects. In relation to controls, subjects treated with valproic acid showed significantly lower values of total and LDL-cholesterol levels; subjects treated with carbamazepine showed significantly higher values of HDL-cholesterol and apolipoprotein A concentrations and subjects treated with phenobarbital showed significantly higher values of total cholesterol, HDL-cholesterol, apolipoprotein A and apolipoprotein B levels. The total cholesterol/HDL-cholesterol ratio was significantly lower in patients receiving valproic acid or carbamazepine but not in the phenobarbital-treated group. Changes in serum lipids profile did not correlate with drug plasma concentrations nor the duration of the treatment.

Abstract
A study of female prostitutes in Manila who tested positive for human immunodeficiency virus (HIV) antibody ascertained demographic and sexual behavior information following diagnosis. Counselling alone did not appear to have a major impact on the sexual behavior of the HIV positive women since most continued to work as prostitutes. Switching from high risk to low risk jobs in bars is not effective in preventing HIV positive women from engaging in prostitution. Revoking work permits is only effective if enforced with adequate follow up. Alternative job training programs may offer a viable approach.
