Urethral Injuries: Diagnostic and Management Strategies for Critical Care and Trauma Clinicians.

Urologic trauma is a well-known cause of urethral injury with a range of management recommendations. Retrograde urethrogram remains the preferred initial diagnostic modality to evaluate a suspected urethral injury. The management thereafter varies based on mechanism of injury. Iatrogenic urethral injury is often caused by traumatic catheterization and is best managed by an attempted catheterization performed by an experienced clinician or suprapubic catheter to maximize urinary drainage. Penetrating trauma, most commonly associated with gunshot wounds, can cause either an anterior and/or posterior urethral injury and is best treated with early operative repair. Blunt trauma, most commonly associated with straddle injuries and pelvic fractures, can be treated with either early primary endoscopic realignment or delayed urethroplasty after suprapubic cystostomy. With any of the above injury patterns and treatment options, a well thought out and regimented follow-up with a urologist is of utmost importance for accurate assessment of outcomes and appropriate management of complications.

Evaluation of the Effects of Amoxicillin on Tooth Development in Rats by Histological and Histomorphometric Study.

Amoxicillin is one of the most commonly prescribed antibiotics in children. As a result, it is prescribed as the first line of defence against cutaneous, gastrointestinal, and respiratory infections. The objective of this study was to evaluate the effects of Amoxicillin on the formation of dentin and enamel during the secretory and early phases of mineralization. Regarding the materials and methods used to perform this study, 16 pregnant adult Wistar rats were equally divided into two groups. The first group did not receive the drug and was prescribed a saline solution (control group), and the other group received 250 mg/kg/day of Amoxicillin (experimental group). From the 13th gestational day until delivery, the treatment was given every day by oral gavage. After birth, the newborns also received the same treatment as their mothers from the first day until 7 or 12 days after birth. The newborns were sacrificed at 7 and 12 days postnatally, the jaws were dissected, the maxilla was taken, the samples were fixed in 10% formaldehyde solution, and the upper first molars were analyzed histologically by H & E stain and histomorphometrically by image J to examine the enamel, dentin, ameloblast and odontoblast mean thickness in both groups and each healing periods. The study's results showed that the mean enamel, as well as ameloblastic and odontoblastic layer thickness, were significantly different in the Amoxicillin 250 mg/kg group, compared to the control group. The result also revealed a non-significant group difference in the dentin thickness in both durations (P-value at day 7=0.147 and the P-value at day 12=0.054). Vacuolization of the ameloblastic and odontoblastic layers was observed in the Amoxicillin-treated group in both durations.

Older Donation After Circulatory Death Kidneys for Older Recipients: A Single-Center Experience.

The number of older patients is increasing on the transplant waiting list. Donation after circulatory death (DCD) kidney transplantation has increased, but there remains hesitancy in use of older DCD organs. The aim of this study was to evaluate outcomes of directing older DCD donor kidneys into older recipients. METHODS: Patients 60 years or older who received transplants from DCD donors 60 years or older, between February 2010 and January 2014, were identified from a prospectively maintained database. RESULTS: Over a 4-year period, 88 patients 60 years or older received DCD kidney transplants from donors 60 years or older. Of these 44 (55%) were 60 to 69 years old and 40 (45%) were 70 years or older. Median follow up was 63 months. Patient survival was 95% and 79% at 1 and 5 years, respectively, with a survival in those 70 years and older (69%) compared with those aged 60 to 69 (88%) years (P = .01). Censored for death graft survival was 94% and 80% at 1 and 5 years, respectively. Median estimated glomerular filtration rate at 12 months and 36 months was 36 mL/min (range, 11-70 mL/min) and 39.5 mL/min (range, 11-77 mL/min), respectively. CONCLUSIONS: Older DCD kidneys, when transplanted into older recipients, result in good patient and graft survival and an acceptable graft function, especially considering their age. This represents a good use of this organ resource.

Diarrea asociada a antibióticos / Antibiotic associated diarrhea

La diarrea asociada a antibióticos es una entidad clínica que ha aumentado de manera considerable los últimos años a nivel mundial. Lo anterior se ha visto favorecido por el incremento en el uso de antibióticos de amplio espectro, los que fundamentalmente alteran la flora intestinal habitual, actuando también por otros mecanismos como la alteración de la motilidad intestinal y acción tóxica directa sobre la mucosa intestinal. La presentación clínica varía desde un cuadro leve hasta de mayor gravedad, llegando incluso a la muerte. Lo anterior dependerá de algunas variables, siendo fundamental el estado inmunitario del paciente. La diarrea asociada a antibióticos por Clostridium Difficile tiene mayor relevancia dado su mayor morbimortalidad. Se han utilizado diversos métodos diagnósticos para evaluar esta patología como así también, diferentes estrategias terapéuticas de enfrentamiento, las que se exponen en la presente revisión

Antibiotic-associated diarrhea is a clinical entity showing a significantly greater presence in past years worldwide. These has been favored by the intensification of treatments based on the use of broad-spectrum antibiotics, which alter intestinal flora and act through other mechanisms like alteration of intestinal motility and direct toxic action on the intestinal mucosa. Clinical symptoms vary from mild to severe and may even cause death. The severity of this condition depends on different variables, mainly the immune status of the patient. Clostridum difficile antibiotic-associated diarrhea is the most relevant since it causes greater mobility and mortality. This article is a review of various diagnostic methods used to evaluate this pathology and multiple therapeutical strategies for management of same.

Suppression subtractive hybridization identifies bacterial genomic regions that are possibly involved in hBD-2 regulation by enterocytes.

SCOPE: Human ß-defensin 2 (hBD-2) is an inducible antimicrobial peptide synthesized by the epithelium to counteract bacterial adherence and invasion. It has been suggested that probiotic bacteria sustain gut barrier function via induction of defensins. The goals of this study were (i) to evaluate the potential immunomodulatory effects of 11 different Lactobacillus fermentum strains isolated from Kimere, an African fermented pearl millet (Pennisetum glaucum) dough, on the hBD-2 secretion by human intestinal CaCo-2 cell line and (ii) to examine genetic differences between two strains of L. fermentum (K2-Lb4 and K11-Lb3) which differed in their effect on the production of hBD-2 in this study. METHODS AND RESULTS: Totally, 46 strains of L. fermentum from Kimere were isolated and characterized using molecular biology methods including pulsed-field gel electrophoresis patterns. After performing time- and dose-experiments, CaCo-2 cells were incubated with or without bacteria for 12 h. L. fermentum PZ1162 was included as the positive control. Cell-free supernatants were analyzed for hBD-2 protein by enzyme-linked immunosorbent assay (ELISA). To identify potential bacterial genes associated with hBD-2 regulation, suppression subtractive hybridization (SSH) was used. Among the 11 strains tested, only two strains of bacteria, K11-Lb3 and K2-Lb6, significantly induced the production of hBD-2 by CaCo-2 cells. This effect was strain-specific, dose-dependent and particularly seems to be bacterial genomic-dependent as manifested by SSH. L. fermentum strains with and without hBD-2 inducing effect differed in genes encoding proteins involved in glycosylation of cell-wall proteins e.g. glycosyltransferase, UDP-N-acetylglucosamine 2-epimerase, rod shape-determining protein MreC, lipoprotein precursors, sugar ABC transporters, and glutamine ABC transporter ATP-binding protein. CONCLUSION: This study implies that certain strains of L. fermentum isolated from Kimere may stimulate the intestinal innate defense through the induction of hBD-2. The molecular basis of hBD-2 induction by L. fermentum strain K11-Lb3 may be based on glycosylated cell-surface structures synthesized with the aid of glycosyltransferase, UDP-N-acetylglucosamine 2-epimerase, and rod shape-determining protein MreC.

[Giant apocrine hydrocystoma of the internal canthus]. / Hidrocystome apocrine géant du canthus interne.

Hydrocystoma is a benign tumor whose development involves the sudoriferous eccrine or apocrine glands. We report the case of a giant apocrine hydrocystoma in a 70-year-old female diabetic patient. The tumor's natural progression over 10 years and its volume caused significant functional and aesthetic damage. This article discusses the radiological, clinical, anatomopathological, and therapeutic aspects of this tumor. The case is original in the tumor's location, size, and its double visual and lachrymal functional involvement as well as its aesthetic damage.

Hallazgos endoscópicos en poblaciones chilenas aisladas: Isla de Pascua y Chile Chico / Endoscopic findings in isolated chilean populations: Isla de Pascua (easter island) and Chile Chico

Chile is a country with high incidence of gastrointestinal diseases, but there are Chilean populations without access to an expeditious endoscopic diagnosis. Easter Island (3.791 inhabitants) and Chile Chico (3.042 inhabitants). Objective: To describe and compare the endoscopic findings in two subgroups of Chilean population of Easter Island (Isla de Pascua) and Chile Chico. Methods: Endoscopic procedures were performed on selected subgroups from Isla de Pascua and Chile Chico during October 2008 and March 2009, in the context of health operations conducted by our hospital. Results: Seventy two patients were evaluated in Isla de Pascua and 52 in Chile Chico. The most frequent endoscopic indications in Isla de Pascua were epigastric pain (22%), heartburn (18.2%), and gastroesophageal reflux (16.2%) and in Chile Chico: gastroesophageal reflux and pirosis (36,5%), epigastric pain (19,3%), and previous gastric ulcer (5.7%). Endoscopic findings in Isla de Pascua and Chile Chico were: gastritis, 26 patients (36.1%) and 5 (9.6%); peptic ulcer 2 (2.7%) and 9 (17.2%); esophagitis 10 (13.8%) and 6 (11.5%); hiatal hernia, 9 (12.5%) and 11 (21%); and endoscopy without lesions 20 (27%) and 13 (25%), respectively. Comparing the findings in both groups the occurrence of two advanced cancers stands out (gastric and esophageal) in the population of Chile Chico; no neoplastic diseases were found in Isla de Pascua. Conclusion: The endoscopic findings in a subgroup of Chileans belonging to isolated populations are described. Differences in the type of digestive diseases suggest that these are different populations despite sharing the same nationality. Future operations will provide a better understanding of these conditions.

La realización de futuros operativos permitirá obtener un mayor conocimiento de las patologías más prevalentes en dichas poblaciones y evaluar la influencia de las...

[Chemical burns caused by the shrub nerium oleander]. / Les Brulures Chimiques Par Le Laurier Rose.

Nerium Oleander is a shrub that grows naturally in the Mediterranean regions. In Morocco it is found in wet places. It is famous for its risk of systemic toxicity in cases of poisoning because of the presence of two alkaloids, especially oleandrine. The literature describes cases of local use of leaves of this plant against scabies, haemorrhoids, and boils. We report two cases of chemical burns of different gravity due to Nerium Oleander. This should lead to more widely diffused information for the general population and strict regulation of its marketing.

Ruptura espontánea de metástasis hepática de cáncer anal espinocelular y hemoperitoneo masivo: reporte de un caso / Spotanous rupture of hepatic metastasis of spinocelular anal cancer and masive hemoperitoneum: case report

Presentamos el caso de un hombre de 61años ingresado al servicio de urgencia por hematemesis y síncope. Previamente había sido tratado por cáncer anal espinocelular sin evidenciade recidiva. Al examen físico destacaba palidez, taquicardia y sudoración. Se realizó endoscopia alta que evidenció lesiones no significativas. El paciente evolucionó con shock hipovolémico y coagulación intravascular diseminada.La tomografía computarizada de abdomen demostró líquido libre intrabdominal y tumor hepático con signos de ruptura. Se realizó laparotomía de urgencia, posteriormente se efectuó embolización selectiva de arteria hepática derecha con buen resultado clínico. La biopsia del tumor hepático resultó compatible con metástasis de cáncer anal espinocelular.

A 61 years old man was admitted in emergency room by syncope and hematemesis. He has been treated by spinocellular carcinoma of the anus without evidence of relapse. At physical examination pallor, sweet and tachycardia, were observed. Upper endoscopy showed no significant lesions. The patient progressed to a hypovolemic shock and intravascular disseminated coagulation. The Abdominal CT revealed massive hemoperitoneum and a single hepatic mass with signs of rupture. The initial treatment was emergency surgery. In a second time selective hepatic artery embolization was done with successful clinical outcome. Biopsy o the liver tumor revealed hepatic metastasis of anal cancer.

Les brûlures électriques sont rares mais graves nécessitant une prise en charge urgente et adéquate car l'évolution peut être émaillée de complications graves, notamment cardiaques, neurologiques et rénales, et les séquelles sont importantes. A travers une étude analytique et rétrospective de janvier 2000 à novembre 2007 ayant inclus 30 patients admis au Service des Brûlés de l'Hôpital Militaire d'Instruction Mohamed V de Rabat, Maroc, pour prise en charge de brûlures électriques, il a été relaté les mécanismes des brûlures électriques, comme aussi les complications, la morbidité et la mortalité, dues aux brûlures électriques, tout en insistant sur les modalités de prise en charge initiale chez ces patients. La prévention reste le point capital pour réduire l'incidence de ces accidents. Cette prévention se base sur la surveillance des enfants et l'élimination de facteurs de risque à la maison, par la maintenance des installations électriques et par l'information et l'éducation du public.

[Detection of gastric preneoplastic lesions with serum levels of pepsinogen in Chilean subjects]. / Detección de lesiones preneoplásicas gástricas mediante niveles séricos de pepsinógeno en población chilena.

BACKGROUND: Gastric cancer has a direct relation with chronic atrophic gastritis (AG) and intestinal metaplasia (IM), considered as preneoplastic lesions. Determination of serum pepsinogen llevéis (PGI) and pepsinogen I / pepsinogen II ratio (PGI/PGII) can detect this conditions; achieving 70-90% of gastric cancer detection in early stages. AIM: To determine the cut-off values for serum PGI and PGI/PGII in Chilean subjects, for the detection of gastric preneoplastic lesions, establishing their sensitivity, specificity, positive (PPV) and negative (NPV) predictive values. PATIENTS AND METHODS: Prospective study of patients subjected to upper gastrointestinal endoscopy and determination of serum pepsinogen levels. The presence and severity of preneoplastic lesions were compared with serum levels of PGI and PGI/PGII. RESULTS: A total of 56 men and 44 women were studied, with a mean age of 43 (14-77) years. There was a significant association (p <0.001) of PGI and PGI/PGII with AG and IM. We obtained a cut-off value of 2.3 for PGI/PGII (sensitivity =70%>, specificity =92%>, PPV =60%>, NPV =95%) and 36 ng/ml for PGI (sensitivity =62%o specificity =64%o, PPV =20%o, NPV =91%), for detection of moderate to severe AG. No patient with normal mucosa had a PGI <20 ng/ml. The combined criteria of PGI/II < or = 2.3 and/or PGI < or 20 ng/ml, obtained a sensitivity of 85%o, specificity of 92%>, PPV of 65%o, and NPV of 97%o. CONCLUSIONS: We confirmed a strict relation ofPGIand PGI/PGIIwith the presence of preneoplastic gastric lesions in Chilean patients.

Tumores del estroma gastrointestinal (GIST): revisión de la literatura / Gastrointestinal stromal tumors (gist): literature review

Los tumores del estroma gastrointestinal representan un tipo infrecuente de tumor de origen mesenquimático, con origen en las células intersticiales de Cajal. Se caracterizan por expresar un receptor de membrana mutante con actividad tirosina quinasa anormal (c-kit CD117) que condiciona su activación permanente y una proliferación celular no controlada. Pueden encontrarse a cualquier nivel del tracto gastrointestinal, pero son más frecuentes en estómago e intestino delgado. Frecuentemente cursan de forma asintomática, constituyendo un hallazgo endoscópico o radiológico. La enfermedad localizada habitualmente es de buen pronóstico tras su resección quirúrgica, mientras que la sobrevida es baja en etapas avanzadas, con escasa respuesta a la quimioterapia convencional. El surgimiento del imatinib, un inhibidor de la tirosina quinasa, ha representado un verdadero hito, dado su eficacia en el control de la enfermedad irresecable o metastásica, permitiendo un importante aumento en la sobrevida de estos pacientes.
