The calcifying odontogenic cyst (COC) is rare and represents <1% of all odontogenic cysts, it belongs to the lesions known as “ghost cell tumors”, these are a family of lesions that vary in clinical presentation of cyst or solid neoplasia, in their behavior biological from benign to locally aggressive or metastatic, this diversity has generated extensive debate on the classification, terminology, management and prognosis of these pathologies. We present the clinical case of a 17-year-old male patient with a diagnosis of calcifying odontogenic cyst associated with a complex odontoma located in the posterior region of the maxilla, in the literature there are only 27 reported cases of (COC) in that area, he was treated by surgical enucleation, curettage, rotation of the buccal fat pad and placement of titanium mesh to reconstruct the anterior wall of the maxillary sinus. The clinical...

La microplaca fue incubada a 28 °C por cuatro días, posteriormente se añadió difeniltetrazolio bromuro (MTT) y...

Objetive. Standardize a new immunohistochemical protocol to identify Helicobacter pylori in gastric biopsies. Materials and Methods: the work was carried out in three phases. The first phase makes use of polyclonal rabbit Anti-H. pylori antibodies as a primary antibody for the labeling of said bacteria, in addition to an EnVision FLEX / HRP polymer for labeling in gastric biopsies. In the second, the immunostaining contrast was modified with the Harris Hematoxylin and Eosin Y dyes, in order to more clearly appreciate the cytomorphology of the gastric tissue to be examined and the possible pre-malignant histological changes. Finally, the results were evaluated against Hematoxylin and Eosin (H&E) staining. Results and Discussion: We show that by carrying out the new immunohistochemistry protocol, it facilitates the identification of H. pylori and, in turn, allows the evaluation of cyto...

OBJECTIVE. To identify risk factors associated to maternal mortality. DESIGN.- Cross sectional study of maternal mortality using the perinatal informatic system of the Obstetrics and Gynecology Department of Hospital Marla Auxiliadora of 21621 cases recorded from July 1, 1988 to December 31, 1992. We used a 2 x 2 table confidence interval 95% test to calculate relative risk (RR) taking social antroprometric, biologic and obstetric variables. RESULTS: The most important risk factors were: single status, no antenatal care, eclampsia, tuberculosis, puerperal infection, second trimester hemorrhage, preterm delivery, anemia, third trimester hemorrhage, septic abortion and urinary infection. CONCLUSION.- There is an association between maternal mortality and no antenatal care, single status and prevalent pathologies of pregnancy.

The objective of this study was to identify the spinal nerves that give origin to the brachial plexus and the origin of each of the nerves of the white-tailed deer (Odocoileus virginianus), as well as to compare the results with those reported in the literature for other ruminants. The two brachial plexuses of four specimens (three females and one male) were dissected. The brachial plexus was originated by contribution of the roots of the ventral branches of the spinal nerves from C6 to T1 (3/4), and from C6 to T2 (1/4). From these originated the suprascapular, subscapular, axillary, radial, ulnar, median, thoracodorsal, musculocutaneous, cranial pectoral, pectoral caudal, long thoracic, lateral thoracic, subclavian, and dorsal scapular nerves. The origin of the brachial plexus of O. virginianus was more similar to that reported in cattle. The formation of the nerves presents similaritie...

OBJECTIVE: To determine incidence, evolution, characteristics, and complications of septic abortion in adolescents. DESIGN: Epidemiological study from 1990 through 1996. RESULTS: From 1709 abortions, 285 occurred in adolescents. General abortion rate was 274,5 per 1 000 lnb, in non-adolescents 290 and in adolescents 203. Incidence ofseptic abortion was 16,7%, distributed in 16,1% in patients over 19 years and 20,5% in adolescents (p < 0,05), especially at ages 18 and 19; 42% had pregnancy interruption above 12 weeks gestation: 27% had a previous pregnancy. Most frequent complications at hospitalization were anemia and septic shock; hysterectomy wasperformed in 8,5%. CONCLUSION: Sept abortion is tbefirst cause of maternal mortality at our Hospital, butfortunately is less frequent in adolescents.
