Reproductive Parameters of the Dogo Argentino Bitch
Marina Caffaratti,Griselda González,Nora Gorla,Corina Guendulain
Journal of Veterinary Medicine , 2013, DOI: 10.1155/2013/495975
Abstract: The Dogo Argentino (DA) is the first and only breed from Argentina recognized worldwide. Although its morphologic features have been well established, its normal reproductive parameters are not clearly known. The aim of this study was to determine the main DA bitch reproductive parameters. One hundred and forty-nine surveys were obtained from breeders from Córdoba province, Argentina: one for each intact DA bitch from 1 to 14 years old. The DA bitch reached puberty at an average of 8.93 months. The mean duration of vulval bleeding found in this study was 11.11 days. The clinical signs characteristic for proestrous-estrous were vulval edema (89.93%), bleeding during the time of mating (32.21%), holding the tail to the side (95.30%), and docility during mating (85.91%). DA bitches had a whelping rate of 84%. Out of 299 pregnancies, 89.30% exhibited a normal parturition, 6.69% presented dystocia, 2.68% needed Cesarean section, and 1.34% aborted. In conclusion, the reproductive parameters of the DA bitch are similar to those identified for other large breeds. DA often showed a prolonged vulval bleeding longer than proestrus. Its high whelping rate, its low incidence of dystocia, and its good maternal ability define the DA as a good reproductive breed with normal reproductive functions. 1. Introduction The Dogo Argentino (DA) is so far the only breed from Argentina recognized by the Fédération Cynologique Internationale (1973). Even though it is known as a big-game hunting dog, it is now also used as companion and guard dog. Its morphologic features have been very well established; however, its normal reproductive parameters are not clearly known. This knowledge is essential to achieve a proper reproductive management, to determine the ideal time of mating or artificial insemination, to avoid unwanted pregnancies, to estimate whelping date, and to diagnose many pathologies. Domestic dogs are monoestrous and typically nonseasonal breeders, with large individual and breed-specific variations [1]. They reach puberty variably at 6 to 14 months of age, with means positively correlated with breed size [2]. The average of the interestrous interval is 6 months, it ranges from 4 to 12 months depending on breed, age, and individual [3]. The proestrous duration is highly variable, from 6 to 11 days, with an average of 9 days [4]. This stage is characterized by male attraction, nonreceptive bitches, and vulval bleeding. Pseudopregnancy is a physiological syndrome which may occur during diestrous. Its signs are very similar to those typical of pregnant bitches, such as
Divertículos vesicales congénitos en la infancia y reflujo vésico-ureteral

Abstract: objectives: to analyze our series of primary congenital diverticula (pcd) and their association with vesicoureteral reflux. methods: we have taken care of 23 children with pcd. eleven of them had big diverticula ( 2 cm) and twelve small. in the first group, 4 children had vesicoureteral reflux and 5 in the second group. in group a, ureteral reimplantation was performed at the time of diverticulum excision. nor diverticula neither refluxes were operated in group b. results: we analyze separately results in both groups. group a: patients were operated including diverticulum excision. there were not recurrences except in one case with ehler-danlos syndrome. no reimplanted ureter showed postoperative reflux. nevertheless, one case with multiple bladder diverticula without reflux presented reflux after the excision of several diverticula without reimplantation. group b: small diverticula did not undergo surgery. spontaneous outcome of reflux was similar to that of the general population without diverticula. conclusions: bladder diverticula are frequently associated with vesicoureteral reflux. the presence of reflux is not an absolute condition for surgical or endoscopic treatment. when diverticula are big in size (group a) the indication for surgery comes from recurrent infection or voiding disorders, not from reflux. if they undergo surgery, ureteral reimplantation is performed in the case they had reflux or for technical reasons like bladder wall weakness. when diverticula are small (group b) the presence of reflux does not condition treatment, being the rate of spontaneous resolution similar to the general population.
Psychopathology of Joseph Stalin  [PDF]
Marina Stal
Psychology (PSYCH) , 2013, DOI: 10.4236/psych.2013.49A1001

Between 1928 and 1953, Joseph Stalin was the undisputed totalitarian dictator of the former Soviet Union whose “reign of fear” continues to maintain its egregious reputation. An examination of Stalin’s documented behaviors attempts to evaluate any signs of psychopathology in accordance with DSM-IV-TR criteria. Evidence of a troubled upbringing, depression, paranoia, and alcohol abuse suggests psychopathology as an implicating factor behind Stalin’s actions. Utilizing such a perspective may allow for future distinctions of individuals deemed responsible for horrendous atrocities.

The Role of Group Size and Correlated Project Outcomes in Group Lending  [PDF]
Marina Markheim
Theoretical Economics Letters (TEL) , 2017, DOI: 10.4236/tel.2017.75080
Abstract: This paper analyzes contract efficiency with regard to correlated project realization and the size of the borrowers in group lending. Firstly, I show that under the standard assumption of independent project payoffs, the expected group cost of default decreases with group size. Secondly, I show that small groups can also optimize group efficiency if individual payoffs and credit risks are correlated. The results outline that social cost minimization occurs due to a common interest in forming optimal borrower groups between lenders and borrowers.
On a New Index Aimed at Comparing Risks  [PDF]
Marina Resta, Maria Erminia Marina
Journal of Mathematical Finance (JMF) , 2015, DOI: 10.4236/jmf.2015.52011
Abstract: This paper fits into the research stream started by Aumann and Serrano (2008) with their index RAS, and introduces a new index of riskiness called Iθ. In particular, our intuition moves from the observation that the RAS index is defined over the set of gambles whose expected value of losses is lower than the one of gains. We then restrict the attention on investment opportunities in a proper relation with a benchmark value \"\" and we build the index Iθ. The mathematical features of the new index are discussed in deepest detail, providing evidence that Iθ can be used by the investor in comparing risks: θ plays the role of a threshold value such that once fixed in the range (0,1] , Iθ suggests to take into consideration a gamble (an investment, an asset) g only if the ratio between the expected value of its losses and the expected value of its gains is lower than such θ. Moreover, Iθ nests RAS as special case when θ = 1, and it satisfies both homogeneity and duality properties. In the light of these features, Iθ seems to satisfy the common need among practitioners for flexible index of riskiness.

Abstract: introduction: prepubertal testicular tumours are different from those that appear during adulthood. traditionally, they were considered to be malignant, however benign testicular tumours are actually more frequent at this age. materials and methods: we analysed our experience in the treatment of testicular tumours in children < 13, with the intention of evaluating the use of partial orchiectomy. from 1984 to 2008, we diagnosed and treated 15 testicular tumours in children at our centre. we examined the therapeutic approach employed, underlining the possibility of testicular conservation in selected patients and we have analysed the results. results: the clinical presentation in 80% of the cases was an increase in testicle size with palpable mass. we performed 4 radical orchiectomies (27%) and 11 tumourectomies (73%). all the benign lesions in the final pathological anatomy were treated with tumourectomy: four epidermoid cysts, one hemangioma, one lipoma, one fibrous hamartoma, one juvenile granulosa tumour and one splenogonadal fusion. we also successfully and conservatively treated two cases of teratoma. the cases that received radical treatment were a yolk sac tumour (stage i), two mixed germ cell tumours and one gonadoblastoma. conclusions: there are more cases of benign testicular tumours than malignant tumours during puberty. in the event of a palpable testicular mass with negative tumour markers, conservative treatment by means of a tumourectomy may be considered. however, the lesion must be removed completely to prevent recurrence.

Abstract: introduction: overactive bladder (ob) is one of the no-neurogenic voiding dysfunctions whose prevalence has been precisely defined among the general population but not so among the paediatric population. its clinical manifestations are various, and its association with other pathologies like enuresis, vesico-ureteral reflux (vur) and recurrent infections is particularly significant in children. ob is basically managed with anticholinergic drugs. the efficacy of oxybutynin chloride has been sufficiently proved; however its dosage and side effects, although scarce in children, usually cause treatment discontinuation. objectives: tolterodine has been successfully used as an alternative therapy of ob in adults, however its use has not been sufficiently evaluated in children. our objective is to determine tolterodine?s efficacy and tolerability in the paediatric population suffering from ob. material and methods: a retrospective study of 72 children who were diagnosed no-neurogenic ob and who received no previous treatment. a concomitant urological pathology diagnostic protocol was applied to all cases, as well as a urodynamic test (udt) and a neurological examination. post-treatment udt was performed to one group of patients. results: the mean age was 10.9 years and the children were assessed between 4 and 31 months after treatment initiation. healing was proved through cistomanometry in 67% of the cases, there was improvement in 14% and 19% of the patients showed no changes in the udt. following the criteria of the international children?s continence society (iccs) applied to those children with no post-treatment udt, 51% were healed, 27% improved and 22% experienced no changes. none of the patients had to discontinue the treatment due to side effects. conclusions: tolterodine?s tolerability and efficacy are good within the paediatric population, which turns it into an alternative to the traditional anticholinergics for the treatment of ob.
Tratamiento quirúrgico del complejo extrofia-epispadias: Revisión y conceptos actuales

Abstract: since earlier descriptions the surgical management of the bladder exstrophy and epispadias complex (beec) has experimented gradual changes in the search for good aesthetic and functional results. the initial urinary diversion and bladder plate removal has evolved under various authors either by improving or supplementing the above described advances, until reaching the staged functional closure and more recently the complete primary beec closure. these later techniques allow to obtain encouraging continence indexes and successful aesthetic results; the low incidence and complexity of this condition however, advises both in terms of early management and later complications that this should be managed in reference centres. sharing on this spirit of technique combination in search for a satisfactory result for exstrophic newborns and inspired by leadbetter?s contribution to young-dees?s procedure for vesicoureteral reflux (vur) correction, we have added a new step to the complete primary beec closure known as the mitchell?s technique by performing gil-vernet?s trigonoplasty to prevent vur, closely associated to bladder exstrophy. we believe vur can be prevented right from the first surgical approach in the exstrophic newborn.

Abstract: objective: to review our experience in renal retransplantations. materials and methods: we carried out a retrospective study on 71 patients with retransplantation performed between 1980 and 2005. we studied: the characteristics of the recipient and graft, surgery data, causes of loss of the graft, number of rejects and transplantectomies and, survival of the graft. results: the most frequent cause of graft loss was chronic rejection. the causes of first graft loss were not associated with a greater loss of the second graft (p>0.05). the percentage of anti-hla antibodies increased in the second transplant in comparison to the first (17.23±27.91% vs. 1.21±7.43%) (p=0.001), however, it was not correlated with a significant increase in loss of the second graft (p=0.320). there were no significant differences between the complications of the first and second transplants (p>0.05) and they were not associated with graft loss (p>0.05). the patients with a transplantectomy in the first transplant presented a risk 8.5 times higher of undergoing a second one (p=0.0001; or: 8.54; ci: 95% 0.941 - 77.501). the most frequent cause of transplantectomies in the second transplant was acute rejection. acute rejection as a cause for transplantectomy in the first transplant proved to be an independent risk factor of transplantectomy of the second transplant (p=0.009). the mean survival of the second graft was 5.08±4.81 years, higher than the first transplant (p=0.133). the survival of the graft at 1.5 and 10 years was 83%, 75% and 52%, respectively. conclusions: the survival of the second transplant was not lower than the first, neither was there an increase in the number of complications.
