Background: Hermaphroditism or intersex is a general term that includes various congenital anomalies of the genital system which is used to define animals with ambiguous sexual characteristics. It occurs in domestic animals, more commonly in pigs and goats, and rarely in horses, dogs, sheep, and cattle. The prevalence of hermaphroditism varies a lot among breeds and species and is higher in groups with a high degree of consanguinity. Therefore, the objective of this report is to describe a case of canine hermaphroditism in a dog with male phenotype, as well as the anatomical and hormonal findings, and classification of the hermaphroditism exhibited by the animal studied.Case: A 1-year-old, mongrel, 5 kg dog was referred to the UHV-UECE due to the presence of a slit on the lower quadrant of the abdomen, caudal to the umbilical scar. At examination, the animal exhibited normal rectal temperature, no alterations of palpable lymph nodes, and a satisfactory body condition score. The pubic area had 2 testicles, each one in a different scrotum, 1 to the right and 1 to the left of the slit. A prepuce with no apparent function was present cranially to the slit, closer to the umbilical scar. At the other extremity of the slit, on the pubic region, there was a flaccid structure similar to a penis (micropenis) with no penile bone and no function. The slit was open until the area ventral to the anus, where the urethra was detected. The animal exhibited a behavior of territory demarcation with urine typically seen in male dogs. Orchiectomy and slit correction surgery were performed. Pre-surgical exams included: complete blood count and hormonal doses of estradiol, testosterone, and progesterone. Abdominal ultrasound was performed to assess presence of sexual glands and gonads. The hormonal exam revealed: estradiol 56.39 pg/mL; testosterone 127.9 ng/mL; progesterone 0.892 ng/mL. A uterus was not detected on ultrasound examination. Ovaries were seen on their typical anatomical position; they were symmetrical and had normal sizes. There was a normal size prostate in the pelvic area, exhibiting normal texture and echogenicity. No other abnormalities were seen and the owner opted for no further surgical intervention.Discussion: Testosterone predominance explains the male behavior and appearance, demonstrating that the testis were prevalent over the ovaries. The occurrence of XX males has been reported. The genetic cause is the absence of the SRY chromosome, which has a fundamental role on activation of the SOX gene, which is responsible for sex determination. Clinically, a true hermaphrodite can exhibit different degrees of genital ambiguity; they can be diagnosed during puberty with the emergence of heterosexual characteristics, or as an adult, with infertility or gonadal neoplasia. True hermaphrodites are individuals with testicular and ovarian tissues, either combined in one gonad (ovotestis) or present as two separate gonads. The presence of ovaries and testicles can be confirmed by histology, which was not performed in this study. However, ultrasound findings (prostate and ovaries), and the presence of normal testis and external genitalia without a defined penis or vulva are in accordance with the description of a true hermaphrodite.

Background: A Grey 12-year-old Arabian endurance horse gelding was referred to the SHS Veterinary Center for anorexia, mild colic of 5 days duration, and melena of 1 day duration. The owner reported recurring colic, 12 episodes of mild colic in the previous year. Methods: On admission, vital signs were within normal limits and body condition score was estimated to be 3/9. Results: Packed cell volume (PCV) was 28% [reference range (RR): 31% to 47%] and plasma total protein was 58 g/L (RR: 60 to 80 g/L). Hematochezia was observed. Abdominal ultrasound examination detected no abnormalities. Over the next 12 h, the horse experienced hematochezia and several mild episodes of colic and death. A necropsy was performed. A mass arising from the right dorsal ascending colon near the base of the cecum and extending transmurally from the colonic mucosa into the mesocolon was a 8 cm × 5 cm × 8 cm firm, homogenous, tan mass. The portion of the mass that extended into the colonic lumen was pedunculated, with an ulcerated surface. The adjacent segments of colon were markedly reddened and edematous. Histologically, the mass was comprised of large interweaving sheets of small, spindle cells with ill-defined cell borders embedded in abundant myxomatous matrix. Tumor cells contained scant eosinophilic cytoplasm and oval to elongate nuclei with finely stippled chromatin and inconspicuous nucleoli. Mitotic figures were rare (1/10) high power fields. Tumor infiltrated between the muscularis interna and the muscularis externa at the myenteric plexi. Conclusion: Gross and histologic appearance, were consistent with a diagnosis of gastrointestinal stromal tumor.

We report on a 15-year-old Ghanaian boy, who presented to a district hospital with diabetic ketoacidosis (DKA) but was diagnosed wrongly as a small bowel perforation due to typhoid fever. He presented with weakness, poor feeding, vomiting, and severe abdominal pain. General examination revealed a lethargic, drowsy, and severely dehydrated patient. His abdomen was diffusely tender more in the right ileac fossa. Investigations including complete blood count, blood smear for malaria parasites, urinalysis, and abdominal ultrasound yielded unremarkable results. Hemoglobin level was 12.4 grams per decilitre. He was diagnosed as typhoid ileal perforation and laparotomy was done, but the bowels and all other intra-abdominal organs were found to be normal. A blood glucose test was done intraoperatively, and it found very high hyperglycaemia. This led to the suspicion of DKA, which was confirmed through urine dipstick testing for high urine ketones and a high glycated hemoglobin (HbA1C) test result. He was then treated for DKA, which resolved on the second day of admission, but the surgical wound healed after twelve days.Our account emphasizes the need for testing for blood glucose in critically ill children and adolescents with suspected severe infections or acute medical conditions that require admission or surgical intervention. This owes to the fact that the clinical features of undiagnosed diabetes, especially if it progresses to DKA, are similar to those of infections and disorders managed via surgical treatment, which are rather more common in Ghana and Africa.

Background: Dioctophymosis is caused by Dioctophyma renale, a parasite known as the giant kidney worm, that can parasitize the kidneys of domestic and wild animals. There are also reports of its occurrence in humans, thus revealing its zoonotic potential. In most cases, parasitized animals are asymptomatic. This parasite can cause atrophy or destroy the renal parenchyma, although ectopic locations may occur. The diagnosis is made through ultrasonography, based on the presence of eggs in the urine, visualization of the parasite, or during necropsy. Therefore, the aim of this work was to report the case of a young dog infected with D. renale and subjected to nephrectomy in the state of Mato Grosso do Sul, Brazil.Case: A 6-month-old bitch with a clinical suspicion of hydronephrosis in the right kidney was referred to the Veterinary Hospital of Anhanguera-Uniderp University in the city of Campo Grande, MS. A physical examination of the patient revealed an alteration in the urinary system.  An abdominal ultrasound, urinalysis, complete blood count (CBC) tests and biochemical profile were ordered. The erythrogram indicated erythrocytosis resulting from dehydration and loss of body fluids, while enzyme levels (creatinine, urea, alanine aminotransferase [ALT] and albumin) were within normal limits. The abdominal ultrasound showed the presence of a cylindrical and rounded structure characteristic of a nematode and in the right kidney, and loss of renal parenchyma typical of D. renale infection. A urinalysis then revealed the presence of helminth eggs, confirming the diagnosis. The owner was informed about the need for nephrectomy of the affected right kidney, which showed destruction of the renal parenchyma. One adult female and one adult male parasite were removed from inside the kidney, measuring approximately 50 cm and 35 cm in length. The patient was successfully treated, kept in hospital for observation, and returned two weeks later for reassessment of her renal function and removal of stitches. Discussion: Dioctophymosis is often diagnosed based on ultrasound and urine tests. These tests proved sufficient to diagnose parasitism by D. renale. However, the infection is usually discovered during necropsy.  D. renale is popularly known as the giant kidney worm, as it can reach up to 100 cm in length. In the present case, the female parasite was 50 cm long and the male was 35 cm. The patient presented parasitism very young, at just 6 months of age. The parasitic infection of the animal was attributed to the ingestion of water or food contaminated with an intermediate host, the aquatic annelid Lumbriculus variegatus. It is suggested that the ingestion of food or water contaminated with the infective stage of the parasite may have occurred at 2 months of age or younger, since the prepatent period is approximately 6 months. The parasite was found only in the patient’s right kidney. Hydronephrosis was reported in the patient and was caused by obstruction of the internal urethral ostium by the adult nematode. In this case, the recommended surgical treatment was nephrectomy, to which the patient was subjected, leading to successful recovery. This case occurred in the state of Mato Grosso do Sul, where there are no records of parasitism by D. renale in domestic dogs, unlike other states in Brazil. We therefore emphasize the importance of new studies on D. renale, given the lack of clear records describing the parasite’s epidemiological data, biological cycle and diagnosis, which may hinder the prevention and control of this zoonotic disease.Keywords: canine dioctophymosis, helminth, nematoid, giant kidney worm, hydronephrosis.Descritores: dioctofimose canina, helminto, nematoide, verme gigante renal, hidronefrose.

AbstractObjectivesTo study the expression of growth factors in the regulation of tissue repair after peritoneal damage tissue response to peritoneal damage.MethodsExperimental study in 35 male Wistar rats determining the evolution over time of the tissue response to aseptic peritoneal damage. A standardized bowel and peritoneal lesions were created in the right lower quadrant by laparotomy. Then, tissular expression of growth factors was evaluated by multiplex polymerase chain reaction at seven timepoints between 6 h and 30 days, postoperatively.ResultsTissular responses of granulocyte-stimulating factors (Csf2, Csf3), connective tissue growth factor (Ctgf), epidermal growth factors and receptor (Egf, Egfr), fibroblast growth factors (Fgf2, 7 and 10), heparin binding EGF-like growth factor (Hbegf), hepatocyte growth factor (Hgf), insulin-like growth factor-1 (Igf1), mitogenic transforming growth factors (Tgfa, Tgfb1, Tgfbr3), and vascular endothelial growth factor A (Vegfa) were biphasic with a first expression peak at day 3, followed by a more pronounced peak at day 14.ConclusionsWe observed a long-lasting, widespread response of tissular growth factors for at least two weeks after peritoneal damage. To be clinically effective, the prophylaxis of postoperative adhesions might be needed for an extended period of time.

Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is a sexual developmental disorder. In this disorder, there is a congenital absence of the uterus and vagina with normal external genitalia. The etiology is not well understood. Variations of this condition exist that may include congenital abnormalities and psychological problems. In this article, we discuss the case of a 47-year-old African American female who presented with acute renal failure, solitary right kidney, and a pelvic mass extending from the pelvis to the right hypochondrium determined to be a fibroid. The patient was managed by a multidisciplinary team, dialyzed, and planned for removal of the mass. While understanding the low probability of having fibroids without a uterus, fibroids should not be excluded from such patients. It is also important to consider the emotional and psychological well-being of such patients.

Abstract Intestinal obstruction caused by pericecal internal herniation are rare and only described in a few cases. This case describes an 80-year-old man presented with acute abdominal pain, nausea and vomiting, with no prior surgical history. Computed tomography was performed and showed a closed loop short bowel obstruction in the right lower quadrant and ascites. Laparoscopy revealed pericecal internal hernia. This is a viscous protrusion through a defect in the peritoneal cavity. Current operative treatment modalities include minimally invasive surgery. Laparoscopic repair of internal herniation is possible and feasible in experienced hands. It must be included in the differential diagnoses of every patient who presents with abdominal pain. When diagnosed act quick and thorough and expeditiously. Treatment preference should be a laparoscopic procedure.

ABSTRACT A 12-year old, 46 XX true hermaphrodite born with genital ambiguity was studied and successfully treated. The serum LH and FSH profile resembled that of a pubertal normal individual, and LH-RH administration induced a normal LH response. Baseline testosterone serum levels were within the range for normal children. Exogenous HCG stimulation induced a significant serum testosterone increase up to values similar to those observed in normal post-pubertal males. Surgical examination disclosed the presence of bilateral ovotestis, normal Mullerian derivatives, epididymis, and vas deferens. A complete ovotestis with testicular predominance and the testicular portion of the contralateral ovotestis as well as the Wolffian derivatives, were removed. A further HCG stimulation 3 months after surgery, failed to induce serum testosterone increase. Spontaneous menarche was observed 6 months after surgery and ovulation was well documented. At present the patient has several characteristics of female sex including those of chromosome complement, gonad, internal and external genitalia, hormone levels and gender identity, thus demonstrating that treatment was successful and that reproductive function could be obtained. The finding of spontaneous ovulation following removal of the testicular portion suggests normal cyclic gonadotrophic release implying a difference between animal models and man in regard to hypothalamic virilization.

CONTEXT AND OBJECTIVE: 45,X/46,XY mosaicism, or mixed gonadal dysgenesis, is considered to be a rare disorder of sex development. The aim of our study was to investigate the clinical and cytogenetic characteristics of patients with this mosaicism.DESIGN AND SETTING: A retrospective study in a referral hospital in southern Brazil.METHODS: Our sample consisted of patients diagnosed at the clinical genetics service of a referral hospital in southern Brazil, from 1975 to 2012. Clinical and cytogenetic data were collected from the medical records.RESULTS: Fourteen patients were included in the sample, with ages at the first evaluation ranging from 2 days to 38 years. Nine of them had female sex of rearing and five, male. Regarding the external genitalia, most were ambiguous (n = 10). One patient presented male phenotype and was treated for a history of azoospermia, while three patients presented female phenotype, of whom two had findings of Turner syndrome and one presented secondary amenorrhea alone. Some findings of Turner syndrome were observed even among patients with ambiguous genitalia. None presented gonadal malignancy. One patient underwent surgical correction for genital ambiguity and subsequent exchange of sex of rearing. Regarding cytogenetics, we did not observe any direct correlation between percentages of cell lines and phenotype.CONCLUSIONS: 45,X/46,XY mosaicism can present with a wide variety of phenotypes resulting from the involvement of different aspects of the individual. All these observations have important implications for early recognition of these patients and their appropriate management.

Abstract. To clarify the origin of the genital ambiguity occasionally associated with the XX male syndrome, a series of endocrinological studies were undertaken in an affected 6 months old infant with perineoscrotal hypospadias. The patient fulfilled all the diagnostic criteria of the syndrome: the testes were descended bilaterally, the Mullerian derivatives were absent, the 46,XX chromosome complement was ascertained in different cell lines, and male levels of H-Y antigen were detected in cultured skin fibroblasts. Circulating gonadotrophin levels and pituitary LRH responsiveness were within normal limits for the age group. Serum testosterone (T) levels were normal, and gonadal stimulation with hCG caused a significant rise on serum T. Incubations of [3H]T with fibroblasts from genital skin revealed normal activity of steroid 5α-reductase. Moreover, normal concentrations of thermostable cytosol androgen receptors were revealed in cultured fibroblasts. Altogether the results indicated that ambiguity of the external genitalia in this patient was the result of neither abnormal T biosynthesis, peripheral A-ring T reduction, nor androgen intracellular specific binding, and suggested that the nature of the imcomplete virilization could be a non-endocrine independent event associated to this disorder. The data are also consistent with the notion that testicular impairment observed in adult XX males develops later in life.
