In some patients it is associated with organic etiology, in others with mental disorders, also occurs in those without disorders in their medical history. Pseudocyesis occurs in both sexes, but more frequently in women. An effective treatment is a combination of psychotherapy and pharmacotherapy with antidepressants and antipsychotics [2]. We present a 15,9-year old girl with pseudocyesis as a cause of abdomen enlargement, who comes from an ordinary family with a negative history of psychiat- ric illness. The organic etiology of her condition was excluded, and therefore she was treated with antidepressants which contributed to the resolution of her case.

  • Different Responsiveness to Progesterone for Induction of Pseudopregnancy Between the First and the Third Estrous Cycle After Vaginal Opening in Rats
    September 1990 Jpn J Anim Reprod Vol 36 (3) Different Responsiveness to Progesterone for Induction of Pseudopregnancy between the First and the Third Estrous Cycle after Vaginal Opening in Rats Hiroshi TOMOGANE and Akira YOKOYAMA Departmentof Animal Science,School of Agriculture,Nagoya University,Chikusa, Nagoya 464-01, Japan (Accepted for publication May 16, 1990) Summary. Effects of progesterone on the function of corpus luteum in estrous cycle were compared between the first and the third estrous cycle after vaginal opening in rats. When 2.5 mg/100 g body weight (B.W.) progesterone was administered between 07:00 and 08:00 hr on the day of estrus or on day 1 of diestrus to rats showing the first estrous cycle, the diestrous period was persisted more than 9 days in 95% of animals. In the diestrous period, plasma prolactin (PRL) level showed daily changes and corpora lutea became functional. The luteal function was enhanced by the deciduoma formed after uterine traumatization on day 3 of diestrus. However, in rats showing the third estrous cycle, 7.5 mg/100 g B.W. progesterone was required to induce similar response to those obtained in the first estrous cycle. Also, no functional corpora lutea and no daily change in PRL secretion were observed in rats injected with progesterone on day 1 of diestrus in the third estrous cycle. These results indicate that progesterone acts more effectively for induction of pseudopregnant diestrus in the first estrous cycle than in the third estrous cycle. KEYWORDS: PSEUDOPREGNANCY, PROGESTERONE, PROLACTIN, PUBERTAL RAT Jpn J Anim Reprod 36, 176-183, 1990 In adult cyclic rats, the corpus luteum has If progesterone administration is limited not become functional, unless the cervical to the early morning of day of estrus in adult stimulus is given.

Several programs exist to control their numbers through lethal removal, using tools such as baiting with toxins. Adult male cats are especially difficult to control. We hypothesized that one way to capture these male cats is to lure them using female cats. As female cats are seasonal breeders, a method is needed to artificially induce reproductive (estrous) behavior so that they could be used for this purpose year-round (i.e., regardless of season).

  • Pseudopregnancy in Bitch. How to Support the Owner and the Animal?
    Pseudopregnancy in bitch. How to support the owner and the animal? Michał Jank, DVM Tomasz Ciszewski, DVM Almost every owner of an unspayed female dog must have experienced at least once the symptoms of pseudopregnancy in their pet. These symptoms, even if sometimes significantly different in terms of their intensity and duration, always cause worries and in most cases make the owner seek advice at a veterinary surgery. Even though the most effective solution to this problem remains hormonal therapy, many owners search for other solutions which will be either more “natural” or economically beneficial. Introduction Pseudopregnancy always accompanies the long luteal phase in unspayed and not pregnant female dogs. It is a physiological condition, typical for canine and results mainly from a specific course of the reproduction of free-living animals representing this genus. In free-living packs of canines it is only one female dog (the alpha female) which is really pregnant, while other females are psudo-pregnant in order to prepare their lactation for the time when the alpha female delivers. Thus the pack protects itself in the case the alpha female is too weak after the labour to take care of the newborns or she becomes an easy target for other predators. In such situations other females in the pack begin their lactation exactly at the moment of the labour (the canine luteal phase always lasts for more or less the same period of time irrespective of whether the female is really or pseudo- pregnant) and they act as “wet nurses” thanks to which the little ones increase their chances of survival even if their biological mother dies.

  • Canine Reproductive Disorders
    Vet Times The website for the veterinary profession https://www.vettimes.co.uk Canine reproductive disorders Author : Jennifer Cartwright Categories : RVNs Date : November 1, 2011 Jennifer Cartwright RVN A1, discusses the variety of issues that can lead an owner to ask if their pet should be neutered Summary INpractice, while running our nurse clinics, we are often asked about the benefits of neutering. This is something a nurse should feel confident speaking about, as this will give clients faith in your knowledge and confidence in your practice. It is very stressful for clients to leave their pet with the practice, but if they trust you it makes the experience a little easier for them. This article aims to recap and revise common reproductive disorders in the dog and provide the reader with a better understanding when answering the “should I neuter my dog?” question. For ease of reading, the article is separated into female and male conditions. Key words neutering, reproduction, prevention, hormonal, congenital Conditions affecting female dogs Follicular cysts This condition is most common in older bitches that have previously had normal seasons. • Symptoms. The bitch will tend to have a longer pro-oestrus and a thickened vulval discharge for 1 / 7 approximately four weeks afterwards. The season tends to cease due to the lack of luteinising hormone. • Diagnosis. Ultrasound is useful, as it will show larger follicles, such as cystic follicles. Cytology of the vagina may be useful, as it will show cornified cells that will not alter at late pro-oestrus. Usually, these cells would not be visible at this stage in the cycle.

Heterozygous females showed almost complete failure of lactation attributable to greatly reduced mammary gland development after their first, but not subsequent, pregnancies. Homozygous females were sterile owing to a complete failure of embryonic implantation. Moreover, they presented multiple reproductive abnormalities, including irregular cycles, reduced fertilization rates, defective preimplantation embryonic development, and lack of pseudopregnancy. Half of the homozygous males were infertile or showed reduced fertility.

Summary False pregnancy in bitches has serious economic impact on dog breeders. This study was therefore, designed to look at the incidence in bitches presented at the Veterinary Teaching Hospital, University of Agriculture Makurdi Benue State Nigeria from the year 2012-2017 (5 years) and proofer solution to the problem; data of clinical cases from Hospital record was collected and analyzed based on breed, age, parity and diagnostic method, total number of 15 clinical cases were used in this work. Results show that the incidence of false pregnancy was higher in Russian shepherd 7(46.66 %) followed by Alsatian 5(33.33 %) but lower in Mastiffs 2(8 %) and Rottweiler 1(4 %). Bitches at age 2 years recorded the highest incidence 7(46.66%), followed by a year of age 6(40 %) and lastly those at 4 years 2(13.33 %), there was no incidence those in third 2(13.33 %) and absent in those in second parity 0(0 %).

ABSTRACT Autism spectrum disorder is a complex brain condition characterized by difficulties in social interaction and communication, as well as a tendency toward repetitive behaviors. In its mildest form, autism spectrum disorder can present minor communication challenges in children who are at or above normal intelligence. In its most severe form, comprehensive cognitive deficits and a total lack of communication create permanent dependence. Currently, there is no cure for autism and the focus is on research to develop effective management and prevention strategies.
