The ovarian remnant syndrome (ORS) is an iatrogenic disorder in bitches and queens, which is characterized by recurrence of estrus following surgical spay, due to the presence of a piece of ovarian tissue within the abdominal cavity. In most cases, the remnant ovary is found in the right ovarian pedicle, due to its topographic position, deeper and more cranial than the left ovary. The main clinical signs of ORS in small animals are the heat behavior and the presence of vaginal swelling/secretion, especially in canines. The diagnosis should be performed by means of vaginal cytology when attraction of males is detected, serum estrogen and progesterone levels and/or by challenging test with GnRH or hCG administration. However, vaginal citology is the most suitable and less expensive diagnostic tool. Nowadays the treatment of choice is a new laparotomy or laparoscopy, followed by removal of the remnant ovarian tissue. The surgical treatment has more chances of success if it is performed in the diestrus (i.e., between 15 and 60 days after the detection of attraction of males). Furthermore, a careful and accurate surgical procedure aided by advanced visualization techniques during ovariohysterectomy or ovariectomy is the best way to prevent ORS in companion animals.

Frequentemente, o ovário remanescente está situado no pedículo ovariano direito, sobretudo devido a sua posição topográfica mais profunda e cranial em comparação ao ovário esquerdo. Os principais sinais clínicos de SOR em pequenos animais são cio e presença de edemaciamento/secreção vulvar/vaginal, especialmente em caninos. O diagnóstico deve ser realizado por meio de citologia vaginal quando detecta-se o interesse dos machos pela cópula com a fêmea acometida, dosagem sérica de estrógeno e progesterona e/ou por meio do teste provocativo com administração de GnRH ou hCG. Contudo, citologia vaginal constitui a opção de melhor custo-benefício para o diagnóstico. Atualmente, o tratamento de escolha é cirúrgico por meio de laparotomia exploratória ou laparoscopia, seguido pela remoção do ovário remanescente. O tratamento cirúrgico tem maiores taxas de sucesso quando realizado com o animal em diestro (i.e., entre 15 e 60 dias após detectada a atração dos machos). Ademais, a

Benign idiopathic neonatal convulsions and partial benign childhood epilepsy, the most frequent types of childhood benign epilepsy, are both characterized by partial seizures. This study was performed to determine whether any kind of benign epilepsy with partial seizures occurs in the age range between these two syndromes. We identified 17 cases of benign epilepsy with partial seizures from a review of 442 records collected in a 5-year period in which seizures occurred between 8 days and 3 years of age. Six patients with onset before 6 weeks of life had clinical features characteristic of benign idiopathic neonatal convulsions, and appeared to be a delayed type of this syndrome. Eleven patients had clinical features characteristic of partial benign childhood epilepsy. In the age range between occurrence of these two recognized epileptic syndromes, we identified no case of partial epilepsy with favorable outcome.
