Epidermolysis bullosa with pyloric atresia: Report of two cases in consecutive siblings / [Epidermólisis ampollosa con atresia pilórica: reporte de dos casos en hermanos consecutivos].

Pyloric atresia is a rare digestive malformation. It represents about 1% of intestinal atresias and is associated with some other genetic or anatomical alteration in 55% of the cases. In 20% of them, it is associated with epidermolysis bullosa, which is described as an established syndrome with a bad prognosis. We present two cases of consecutive siblings with this condition and fatal outcomes in both of them. We made a review of the literature and discussed the main topics.

La atresia pilórica es una malformación digestiva poco frecuente y representa alrededor del 1 % de las atresias intestinales. En el 55 % de los casos, se asocia con alguna otra alteración genética o anatómica, especialmente la epidermólisis ampollosa, que se presenta en el 20 % de ellos, en una asociación que se describe como un síndrome de mal pronóstico. Se presentan dos casos de hermanos consecutivos con esta condición, ambos con un desenlace fatal. Se hizo, además, una revisión de la literatura y se expusieron los puntos más importantes.

Contenção emergencial após traumatismo dental com fratura óssea em bloco: uso de microparafusos / Dental trauma emergency with block bone fracture: contention using micro screws

Traumas dentários envolvem dentes anteriores, influenciando função e estética de crianças e adultos jovens de diversas idades em diferentes especialidades odontológicas. Os dentes mais frequentemente envolvidos são incisivos centrais superiores, incisivos laterais superiores e incisivos centrais inferiores. A proposta deste trabalho foi apresentar caso clínico de traumatismo envolvendo fratura óssea em bloco. Após acidente o paciente foi atendido e ao exame clínico constatou-se fratura em bloco dos elementos dentais 42,41,31,32 e avulsão do 33 com tecido gengival e mucoso dilacerados. Radiograficamente observou-se fratura horizontal do osso mandibular, avulsão dos dentes de seus alvéolos em bloco e diversos fragmentos ósseos. Seguiu-se cirurgia imediata, valendo-se de contenção emergencial com microparafuso e após 7 dias removeu-se a sutura. Realizou-se acompanhamento em 14,21 e 28 dias e após 3 meses foi realizado tratamento endodôntico dos dentes 31, 32, 41 e 42. Os procedimentos realizados alcançaram êxito após a realização dos atendimentos.

Dental traumas involve anterior teeth, affecting both function and aesthetics of children and young adults of different ages in different dental specialties The teeth most frequently involved are the maxillary central incisors, lateral incisors and mandibular central incisors. The airn of this work is to present a clinical case of injury involving bone block fracture. After the accident, the patient underwent clinical examination, which revealed block fracture of dental elements 42, 41, 31, 32 and avulsion of 33 with laceration of the gingival and mucosal tissue. Radiographic results revealed horizontal fracture of the jawbone, tooth avulsion of its wells in the block and several bone fragments. Patient underwent immediate surgery using emergency containment with micro-screws, and suture was removed seven days after. Monitoring was performed at 14,21 and 28 days and endodontic treatment of teeth 31,32,41 and 42 was performed 3 months after. Ali procedures were successful.

Metastatic adenocarcinoma of the colon: early manifestation in gingival tissue.

A case of gingival metastasis of adenocarcinoma of the colon is reported, the lesion being an early clinical indication of a primary malignant tumor. The diagnosis of metastatic lesion in the oral region is always challenging, both to clinician and to the pathologist, due to its rarity and complexity. In the present case, the clinical hypothesis was peripheral ossifying fibroma or pyogenic granuloma. Histologically, the biopsy tissue revealed a malignant neoplasm not connected to the mucosal surface. Immunohistochemically, the lesion was positive for 35ßH11 and cytokeratin 20 and focally positive for cytokeratin 7. Treatment involved excision of primary tumor and follow-up chemotherapy. The clinical, histological and immunohistochemical characteristics are discussed.

Electroejaculation and seminal characteristics in chinchilla (Chinchilla laniger) / Eletroejaculação e características seminais em chinchila (Chinchilla laniger)

Semen collection in Chinchilla was attained through electroejaculation with an electrode inserted 3cm deep in the rectum, utilizing a series of 9 shocks of 12.5 mA, 6 shocks of 25.0 mA and 19 shocks of 50.0 mA. Material obtained was considered of good quality, both for freezing and thawing.

O método da eletroejaculação foi utilizado em chinchila através de eletrodo introduzido a 3 cm no reto do animal, obtendo-se os melhores resultados com uma série de 9 choques de 12,5 mA, 6 choques de 25,0 mA e 19 choques de 50,0 mA. O sêmen obtido nestas condições foi considerado de boa qualidade, comportando-se satisfatoriamente tanto no processo de congelamento, quanto no descongelamento.
