Noel Ramdwar, Daniel Cox, Thair Aldujaili
Ileostomy formation is a fundamental component in the surgical management of many gastrointestinal diseases and like all intra-abdominal surgeries, small bowel obstruction is a recognized complication. In this paper we discuss a case of a 44-year-old female who previously had a loop ileostomy for slow bowel transit in the presence of spinal bifida. She presented for subsequent total colectomy because of ongoing pain due to chronic colonic dilation. At surgery, the stoma was not revised and the efferent loop was divided at the peritoneal level of the anterior abdominal wall...

A 41-year-old man with no medical history presented with 2 weeks of nausea, vomiting, a new palpable abdominal mass, constipation and a 14kgweight loss. On admission, CT abdomen and pelvis demonstrated a 6.9×3.7 cm soft-tissue abdominal mass deep to and invading the lower anterior abdominal wall with tethering of the urinary bladder and potential involvement of the urachus. Subsequently, a biopsy demonstrated a low-grade spindle cell neoplasm compatible with inflammatory myofibroblastic tumour with immunostain positive for smooth muscle actin and desmin and negative for CD21, CD117, DOG-1, TKE-1, mdm2, CD34 and ALK...

BACKGROUND: We have performed laparoscopic totally extraperitoneal (TEP) repair for inguinal hernia repair for the last 20 years. We use two balloon dilators (sphere and kidney type) to dissect the preperitoneal space for the TEP repair. It may be difficult to obtain exposure in patients who previously underwent lower abdominal surgery, because of adhesions to the abdominal wall. We reviewed our experience with inguinal hernia repairs to retrospectively analyze factors that limit the laparoscopic TEP approach...

Medical research suggests that the anterior-posterior (AP)-diameter of the inferior vena cava (IVC) and its associated temporal variation as imaged by bedside ultrasound is useful in guiding fluid resuscitation of the critically-ill patient. Unfortunately, indistinct edges and gaps in vessel walls are frequently present which impede accurate estimation of the IVC AP-diameter for both human operators and segmentation algorithms. The majority of research involving use of the IVC to guide fluid resuscitation involves manual measurement of the maximum and minimum AP-diameter as it varies over time...

The muscle-specific ubiquitin ligase atrogin-1 (MAFbx) has been identified as a critical regulator of pathologic and physiologic cardiac hypertrophy; it regulates these processes by ubiquitinating transcription factors (NFAT and FOXO1/3). However, the role of Atrogin-1 in regulating transcription factors in aging has not previously been described. Atrogin-1 cardiomyocyte-specific transgenic (Tg+) adult mice (αMHC promoter driven) have normal cardiac function and size. Here we demonstrate that 18-month-old Atrogin-1 Tg+ hearts exhibit significantly increased anterior wall thickness without functional impairment vs wild-type mice...

The mortality rate of post-infarction cardiogenic shock (CS) was 80.0-90.0%. Recent studies show a significant reduction of hospital mortality to approximately 50.0%. CS is defined as systemic tissue hypoperfusion resulting from systolic and/or diastolic heart dysfunction, the main cause of which is acute myocardial infarction (AMI). The main predictors are biological markers such as troponin, CKMB and lactate. A systematic literature review and meta-analysis is performed in order to present and correlate the main literary findings on CS and its evolution with possible changes in biomarkers such as troponin, lactate and CKMB...

We report a case of atrial septal defect (ASD) with severe pectus excavatum. A 50-year-old female had a stroke due to paradoxical embolism from deep vein thrombosis thorough ASD. Her preoperative computed tomography(CT) revealed a severe pectus excavatum (Haller CT index 28.6). The patient underwent ASD closure and repair of the pectus excavatum concomitantly. Median full sternotomy was performed for ASD closure. And we adopted sterno-costal elevation for pectus excavatum repair. Cartilages of the 3rd to the 7th rib were segmentally resected and the remainders were re-sutured to the sternum...

Although the initial reparative fibrosis after myocardial infarction (MI) is crucial for preventing rupture of the ventricular wall, an exaggerated fibrotic response and reactive fibrosis outside the injured area are detrimental. Although metformin prevents adverse cardiac remodeling, as well as provides glycemic control, the underlying mechanisms remain poorly documented. This study describes the effect of mitochondrial NADPH oxidase 4 (mitoNox) and protein kinase C-alpha (PKCα) on the cardiac fibrosis and galectin 3 (Gal-3) expression...

The traditional green algal genus Chloromonas accommodates mesophilic, cold-tolerant and cold-adapted microorganisms. In this paper we studied a new strain isolated from a wet hummock meadow in the High Arctic. We used morphological, ultrastructural and molecular data to assess the taxonomic position and phylogenetic relationships of the new isolate. The observed morphological features generally corresponded to the cold-tolerant Chloromonas characteristics. However, ellipsoidal or wide ellipsoidal vegetative cells, a massive parietal cup-shaped chloroplast with a number of continuously connected lobes, a thick cell wall, a prominent hemispherical papilla and the anterior position of an oblong or round eyespot distinguished the alga from all previously described Chloromonas species...
