The superior mesenteric artery and the variations of the colic patterns. A new anatomical and radiological classification of the colic arteries.

The superior mesenteric artery (SMA) supplies irrigation to the small intestine, ascending and a variable area of the transverse colon. Although medical imaging and surgical procedures have been widely developed in the last decades, the anatomy of the SMA using advanced imaging technology remains to be elucidated. Previous studies have used small sample sizes of cadaveric or radiological samples to propose a number of classifications for the SMA. In this study, we aimed to provide a more detailed description and useful classification of the SMA and its main branches [middle colic artery (MCA), right colic artery (RCA), and ileocolic artery (ICA)]. Samples (n = 50, 28 males and 22 females) were obtained from the repository of human cadavers located at the Department of Human Anatomy and Embryology, Complutense University of Madrid. This sample was dissected by preclinical medical students and completed by two of the authors (Gamo and Jiménez). A second set of samples was obtained from a bank of computerized tomography (CT) (560 CTs, 399 males and 161 females) collected by the Radiology Department at the Clínico San Carlos Hospital, Spain. Based on the results obtained from these studies, we propose a new classification of four patterns for the SMA anatomy. Pattern I as the independent origin of the three main branches of the SMA (cadaveric 40 %; CT 73.69 %); Pattern II is subdivided in three sub-patterns based on the common trunks of origin: Pattern IIa, common trunk between RCA and MCA (cadaveric 20 %, CT 4.28 %); Pattern IIb, common trunk between RCA and ICA (cadaveric 32 %, CT 15 %); Pattern IIc, common trunk for the three main branches (cadaveric 0 %, CT 0.35 %); Pattern III, as the absence of RCA (cadaveric 8 %; CT 2.32 %) and Pattern IV, based on presence of accessory arteries (not found in any of the samples). Although the independent origin of the three colic arteries have been classically described as the most frequent, the right colic artery is responsible of major variations.

Predictors of good visual outcomes in patients with neovascular age-related macular degeneration in daily practice.

PURPOSE: To report predictive factors for therapeutic response to anti-VEGF in patients with neovascular age-related macular degeneration (nAMD) in daily clinical practice in our patient population. METHODS: Retrospective cohort study including 56 patients (69 eyes) with nAMD treated with anti-VEGF, followed for at least two years between February 2012 and April 2018. Patients received three intravitreal anti-VEGF (bevacizumab) injections (loading dose) and were monitored and treated according to a PRN regimen. We analysed whether a gain in visual acuity of 15 or more ETDRS letters at the final visit was associated with demographic characteristics, presence of systemic comorbidities, fundus lesions or measurable improvement on Cirrus optical coherence tomography (OCT) between the first and last visit. RESULTS: After a mean follow-up of 15.5 months (4.7-27.8 interquartile range), central retinal thickness (CRT) (RR: 1.004; IC 95%: 1.001-1.007; P=0.011) and macular hemorrhage (RR: 0.30; IC 95%: 0.10-0.90, P=0.032) at baseline were found to be useful predictive factors for visual acuity improvement (≥15 letters) in patients treated for nAMD by anti-VEGF in a real world clinical setting. CONCLUSION: In the present series of patients with nAMD receiving a loading dose of bevacizumab and followed according to a PRN regimen for 24 months, the only predictable factors for a ≥15 letter gain in visual acuity were anatomical response as measured by OCT and macular hemorrhage at baseline.

[Hallux metatarsophalangeal arthrodesis: retrospective comparison between blocked plate and cannulated screws]. / Artrodesis metatarsofalángica del hallux: comparación retrospectiva entre placa bloqueada y tornillos canulados.

INTRODUCTION: There are multiple methods and implants used for the metatarsophalangeal arthrodesis of hallux without evidence in favor of one or the other in the bibliography. The goal was to compare the clinical and radiological results of 2 methods and implants used in our center. MATERIAL AND METHODS: Retrospective review of 37 feet between 2013 and 2017 (22 feet by plate and 15 by cannulated screws). Clinical and radiological variables were collected and the AOFAS and Manchester-Oxford scales were applied. Variables were studied descriptively and analytically through the SPSSv15 program. RESULTS: The group intervened by plate was composed of 77% of women, with an average age of 65 years and a distribution by diagnosis of severe hallux valgus (HV) (36%), hallux valgus relapse (HVR) (36%) and hallux rigidus (HR) (28%), compared to 80% of women, 68 years old and HV (34%), HVR (46%) HR (20%) in the group of cannulated screws. No significant differences were found in the correction of angles for HV or HVR. The rate of painful pseudoarthrosis was 13% in both and the re-intervention was 18% in the plate group and 26% in the screw group. Both the AOFAS and M-O scales were better in the plate group 63.8 vs 52.6 (p = 0.07); 30.1 vs 41.0 (p = 0.10); as well as patient satisfaction 86% vs 66% (p 0.05) and postoperative pain 3.68 vs 5.58 (p 0.05). CONCLUSION: Small study groups, not implant randomization, both options are functional without being able to find a preferred one.

Syndrome of Alagille: radiological and sonographic findings. A review of 37 cases.

The objective of this study was to evaluate the association of intrahepatic cholestasis, pulmonary stenosis, and hyperlipemia with osseous and renal abnormalities in Alagille's syndrome. A total of 37 patients (25 males and 12 females) with ages ranging between 8 months and 27 years were included. Clinical records as well as radiological and ultrasonographic studies were reviewed. Chronic cholestasis was observed in all patients. Thirteen had favorable clinical outcome and normal hepatic sonograms. Clinical and sonographic evidence of portal hypertension was found in 13 patients and of cirrhosis in 8 patients. The remaining 3 patients required hepatic transplantation due to severe cholestasis. Hyperlipemia correlated with hepatic malfunction. Pulmonary stenosis and renal hypoplasia were the most frequently associated abnormalities. All patients showed a peculiar facies. Abnormal "butterfly" vertebrae were present in 18 patients and ulnar or phalangeal shortening in 11 patients. Ultrasonography allowed hepatobiliary disease assessment and helped to establish indications for hepatic transplantation. Renal and osseous abnormalities were not specific but in the appropriate clinical setting reinforced the diagnosis.

[Epidemiological study of attempted suicide managed at the hospital emergency department]. / Estudio epidemiológico de las tentativas de suicidio atendidas en la urgencia hospitalaria.

PURPOSE: The authors investigate psychiatric and sociodemographic characteristics of the patients attended at the emergency department in the General Hospital of Mostoles, after their suicidal intent, and of those who repeated a suicidal intent in the first year of follow-up. METHODOLOGY: It is a prospective study, with a duration of one year, in a real sample with 119 patients randomized as a stratified sample from the population attended after their intent. Data recollection was made with a psychiatric semi-structured interview and Beck's letality and suicidal intent scales. Recruitment and follow-up periods were one year long for each of them. Statistical analysis was realized with the chi square test and Fischer's exact test to evaluate associations among cualitative variable and the variance analysis of the relations between qualitative and quantitative variable. RESULTS: Suicide intent ratio was 82/100,000 inhabitants, being in 83% by medicament ingestion. 71% were women, 66% were between 15 and 30 years old, 50% were unmarried and 12% were separated. 33% suffered from a affective disorder, and 23% were alcohol abusers. 6% of them bad a psycotic disorder. 52% of the patients had previous psychiatric disorders and 43% had been in treatment. 46% of them had someone in their families with a psychiatric disorder. 29% were repeaters after a previous attempt. Concerning to a prior contact with the Mental Health Services in the preceding month Significant differences were observed by age, but no significant differences were observed by sex. 26% used alcohol prior to the intent, mainly men. EIB and ELB ratings were significatively higher in retired than in students. Among the patients who repeated their intent (14.5%) of the followed, 78% were women, with an age between 30 and 56 years old. 61% were diagnosed having an affective disorder and 10% had psycotic disorders. 88% of the repeaters were in psychiatric treatment for five years or more.
