Displacement of the non-reduction disk with limitation of opening (DDwLO) can be treatment of the non-surgical form. However, it required scientific and clinic knowledge of diagnostic area of the disorders temporomandibulares. This study was performed with the patient CN, 18 years, white, female, who went to the orofacial pain ambulatory with complaints of extreme pain on the right temporomandibular joint (TMJ) and limitation of maximum opening of 29 mm with shift to right, which she has been suffering for at least three years. After a criterion anamnese the diagnosis hypothesis found was a displacement of the non-reduction disk with limitation of opening. The treatment was based on infiltration in the right TMJ with anesthesic followed by mandibular manipulation. After the therapeutic conduct the patient presented clinical signals of normality with absence of trismus and mandibular movement without shift to right. The patient was followed up during five years not presenting return of the pathology.

The amphetamine derivative 3,4-methylenedioxymethamphetamine (MDMA), also called ecstasy, is a neurotoxin widely consumed among young people that has increased in recent years because it is a recreational drug, of which immediate effects are known such as a greater sensation of well-being, extroversion, increased sensory perception. However, its long-term effects have been described very little in the medical literature, including damage to the heart, central nervous system, kidney, etc. One of its little-known effects is hepatotoxicity, of which few cases are known associated with fulminant hepatitis, which is a rapidly deteriorating condition that is generally associated with a syndrome of multiple organ dysfunction and death. Therefore, it is very important to know this type of damage in the short and long term. The following case is of a 39-year-old man who came to our service due to jaundice syndrome and the only history of MDMA consumption, who as the days went by met the criteria for fulminant liver failure, with damage to multiple organs (organ dysfunction syndrome).

Dieulafoy’s lesions are rare vascular malformations of the gastrointestinal tract. A Dieulafoy’s lesion is an aberrant vessel that does not reduce in caliber when it extends from the submucosa to the mucosa. Damage to this artery can cause severe and intermittent arterial bleeding from small vascular stumps that are difficult to visualize. Furthermore, these catastrophic bleeding episodes frequently result in hemodynamic instability and the need for transfusion of multiple blood products. Recently, uremic syndrome has been identified as a risk factor for gastric mucosal lesions. We present two clinical cases of acute digestive bleeding due to Dielafoy lesion with chronic kidney disease as the main cause, where two different therapies were performed endoscopically. We concluded with the results of our patients that the best therapy was the application of the hemostatic hemoclip on the injury vs the injection with adrenaline on the wound site. Uremia is identified as a risk factor for upper gastrointestinal bleeding in patients with pre-existing Dieulafoy’s lesion, as well as a higher incidence of new bleeding.

Meningoencephalitis secondary to Listeria monocytogenes (L. monocytogenes) mainly affects newborns, the elderly and immunocompromised people;there are extremely rare cases in which said infection occurs in immunocompetent individuals. We present the case of a young adult patient without immunocompromise, who developed meningoencephalitis due to L. monocytogenes;This case is exceptional, since it occurred in an individual outside the classic age group, in addition to not having risk factors, which is why it should be considered an atypical causal agent.

We present an unusual case of portal vein thrombosis with a splanchnic hemangioma secondary to acute biliary pancreatitis. We report a 45-year-old patient, who has systemic arterial hypertension in treatment, was admitted for abdominal pain in the epigastrium, with irradiation to the right hypochondrium, accompanied by nausea and vomiting of 10 occasions of bile content, physical examination with pain in the right hypochondrium, Murphy positive. We have laboratory studies with a lipase of 788, so a diagnosis of pancreatitis is made with an etiology to be determined. The laboratories suggestive of acute biliary pancreatitis (lipase 788.71);an imaging study was subsequently performed (ultrasonography) with the result of stone in the common bile duct. A laparoscopy was performed with relative improvement, so he was discharged and returned 20 days after surgery due to abdominal pain of the same intensity in the left hypochondrium. Ending his hospitalization with a splenectomy for splenic hemangioma with portal vein thrombosis.

Drought is one of the major abiotic stresses often causing negative impacts on bean crops in the Andean region in Colombia. An experiment under the greenhouse conditions was carried out to assess the effect of a prolonged drought period(15 days) at two different phenological stages(vegetative or reproductive) on grain yield and yield components of five bush bean cultivars(ICA-Cerinza, Bachue, NUA35, Bianca, and Bacatá). Nine tolerance indices including stress susceptibility index(SSI), tolerance(TOL), mean productivity(MP), geometric mean productivity(GMP), stress tolerance index(STI), yield stability index(YSI), yield index(YI), Harmonic mean(HM), and drought sensitivity index(DSI) were calculated based on grain yield under non-stressed(YP) and drought(YS) conditions. Based on the different drought indices, genotypes ICA-Cerinza and NUA35 had the best performance under drought conditions in both studied phases, which reflected in a reduction of grain yield ~≤40%. The biplot analysis also showed a clear superiority of these two genotypes at both phenological stages. Results also showed that SSI was more effective to identify genotypes less affected by drought. The above results allowed us to conclude that ICA-Cerinza and NUA35 may be considered for agricultural areas where long periods of water deficit are expected and can be used in breeding programs for drought tolerance.

Introduction: Thyroid states can be associated with psychiatric manifestations, be it hypothyroid, hyperthyroid or even euthyroid. The effect of depression is significant in subclinical hypothyroidism. Sometimes, its signs and symptoms are indistinguishable from Major Depressive Disorder. Our immunological system and early embryologic origins also play a role in the coexistence of other comorbidities like Pernicious Anemia. Case: A 35-year-old Hispanic female presented with significant low mood, somnolence, weight gain, increased hunger, cold intolerance and epigastric pain. It is important to note the variety of clinical manifestations of our hypothyroidism patient to understand its associations and help us with a better approach to treatment. Discussion: Standard approaches to treatment of Subclinical Hypothyroidism will depend mostly on laboratory findings such as TSH levels and free T4. Individualized therapy chosen for our patient was based on his mood symptoms, laboratory findings and coexistence of Pernicious Anemia. The use of daily 0.025 mg of levothyroxine, 10 mg of escitalopram oxalate and weekly injections of cyanocobalamin were treatments of choice. Conclusion: During follow up of our patient, we can conclude that Levothyroxine and Escitalopram Oxalate were able to improve hypothyroidism symptoms, reduce thyroglobulin and peroxidase antibodies and improve mood symptoms including cognitive functions. In addition to this, weekly cyanocobalamin injections were integrated into the management. As parietal cell antibodies decreased, gastrointestinal symptoms also disappeared. By addressing the concerns of our patient, we improved quality of care, and this is reflected in the patient’s wellbeing in physical and psychological.

Hepatic lipidosis is a common lesion in chelonians and may be related with vitellogenesis, hyperparathyroidism, follicular stasis, fatty diets or lacking nutrients, sedentary life and obesity, bacterial toxins in liver and starvation. Clinical signs are unspecific. Routine biochemical tests don＇t have specificity and it is better defined through biopsy. The objective was evaluated the biochemical hepatic profile of red footed tortoises （Chelonoidis carbonaria） with the histopathological findings of lipidosis by laparoscopic biopsy. Samples of blood were collected for biochemistry of thirty-six animals from two different groups, twenty animals from a zoo and sixteen from a breeder. The animals were submitted to liver biopsy by videolaparoscopy. Three fragments were collected, two of them were processed by histology and one went to electron microscopy. Nineteen tortoises from the zoo had lipidosis in laparoscopy and macrovesicular degeneration. Fifteen tortoises from the breeder had microvesicular degeneration. The diagnosis of steatosis was confirmed by electron microscopy. There was no statistical difference of aspartate aminotransferase levels between the two groups; however there was significant difference of triglycerides levels. The enzymatic activity of transaminases is not related to the histological grading of lipidosis in tortoises, however triglycerides levels are higher in animals with more severe gradation.

Background： Removal of the follicular content by ultrasound-guided transvaginal follicle aspiration（TVFA） may fail to induce immediate atresia and loss of function, resulting in the occurrence of residual follicles（RF）. The aims of this study were to characterize the blood flow in RF and to determine the effects of the treatment with estradiol benzoate on RF fate. Lactating, cyclic Holstein-Gir crossbred cows were used. In Experiment 1, follicular wave emergence（D0） was synchronized in cows（n = 10） and follicular growth was then monitored by transrectal ultrasonography from D0 to D8, followed by TVFA of the largest follicle present on the ovaries 24 h later. Color Doppler ultrasound imaging was used to examine blood flow on the follicular wall, which was recorded immediately before and every 12 h after TVFA, up to 72 h. In experiment 2, cows（n = 22） were randomly allocated to receive either 2 mL of saline i.m.（Control group, n = 11） or 2 mL estradiol benzoate i.m.（EB group, n = 11）immediately after TVFA. Ovaries were scanned every 12 h to confirm the presence and to measure the diameter of RF. The contents of the RF, if present, were collected 72 h after the first TVFA, using the same aspiration *** fluid from original follicles and RF were stored at-20 °C until hormonal ***： In Experiment 1, there was no reduction（P 〉 0.05） of blood flow in the remaining follicle walls after TVFA and maximum blood flow values were observed at 49.5 ± 19.7 h post-TVFA. In Experiment 2, formation of RF after TVFA was proportionally similar between Controls（5/9） and EB（5/10） cows. Also, RF diameter did not differ between groups（P 〉 0.05）. Nonetheless, the content of RF from cows in the EB group had lower（P = 0.0004）estradiol（E2） concentration and lower（P = 0.0005） E2：P4 ratio compared with ***： In conclusion, 1） the persistence of vascularization in the remaining follicle wall may contribute to the formation of RF after follicle aspiration,
