Acute epiploic appendagitis mimicking symptoms of urinary tract infection: A diagnostic enigma in the emergency department

The epiploic appendages (also known as appendices epiploicae) are usually located on the anti‐mesenteric surface of the colon, extending from the caecum to the rectosigmoid, and epiploic appendagitis (EA) is the inflammation of these appendages. We report a clinical image of epiploic appendagitis creating a diagnostic challenge.     

Intramyocardial Injection of Autologous Bone Marrow-Derived Ex Vivo Expanded Mesenchymal Stem Cells in Acute Myocardial Infarction Patients is Feasible and Safe up to 5 Years of Follow-up

In experimental studies, mesenchymal stem cell (MSC) transplantation in acute myocardial infarction (AMI) models has been associated with enhanced neovascularization and myogenesis. Clinical data however, are scarce. Therefore, the present study evaluates the safety and feasibility of intramyocardial MSC injection in nine patients, shortly after AMI during short-term and 5-year follow-up. Periprocedural safety analysis demonstrated one transient ischemic attack. No other adverse events related to MSC treatment were observed during 5-year follow-up. Clinical events were compared to a nonrandomized control group comprising 45 matched controls. A 5-year event-free survival after MSC-treatment was comparable to controls (89 vs. 91 %, P?=?0.87). Echocardiographic imaging for evaluation of left ventricular function demonstrated improvements up to 5 years after MSC treatment. These findings were not significantly different when compared to controls. The present safety and feasibility study suggest that intramyocardial injection of MSC in patients shortly after AMI is feasible and safe up to 5-year follow-up.     

Trastuzumab Beyond Progression for HER2 Positive Metastatic Breast Cancer: Progression‐Free Survival on First‐Line Therapy Predicts Overall Survival Impact

Trastuzumab beyond first progression in the metastatic setting has been adopted based on limited data suggesting improved outcomes compared to second‐line chemotherapy alone although predictive factors for preferential benefit remain elusive. We conducted a retrospective review of all patients receiving trastuzumab for HER2 + metastatic disease between Jan 1, 1999–June 15, 2011. Univariate and time to event analyses described treatment and survival patterns. Median duration of each line of therapy and overall survival times for covariates, including treatment era (pre versus post Jan 1, 2005), lines of trastuzumab‐based therapy (1 versus 2 versus 3 + ), first‐line chemotherapy partner (docetaxel/paclitaxel versus other) and median exposure to first‐line trastuzumab‐based therapy (=/> versus < cohort median) were estimated. A total of 119 patients received a median of two lines of trastuzumab‐based therapy (range 1–8). Median overall survival was 21.8 months (95% CI = 14.5–27.1 m), by era was 15.6 m (95% CI = 9.7–24.8 m) versus 26.1 m (95% CI = 20.0–39.3 m; p = 0.11) and by lines of trastuzumab‐based therapy received was 10.6 m (95% CI = 5.3–17.4 m) versus 13.9 m (95% CI = 9.5–27.6 m) versus 32.5 m (95% CI = 25–49.4 m) (p = 0.0014). Median overall survival was significantly longer for those receiving taxanes with trastuzumab compared to other first line partners (26.1 m, 95% CI = 17.8–31.4 m versus 14.5 m, 95% CI = 9.4–21.9 m, p = 0.02). Median overall survival with duration of first‐line trastuzumab‐based therapy =/> cohort median was 31.9 m (95% CI = 26.2–52.2 m) versus 10.3 m for shorter durations (95% CI = 6.9–15.6 m; p < 0.0001). Our observations support progression‐free survival on first‐line trastuzumab‐based therapy as a clinically relevant predictive factor for overall survival benefit with the adoption of a trastuzumab beyond progression treatment strategy.     

Skin Graft Review in Dermofasciectomy for Dupuytren’s Contracture within 48 Hours: Challenging Historical Practice

Introduction  Early review of skin graft following dermofasciectomy with skin grafting for Dupuytren’s disease is not standard practice because of the potentially adverse effects on inosculation and neovascularization process of the skin grafting. The purpose of this retrospective case series was to observe whether early review of grafts postoperatively at 48 hours adversely affects graft survival and surgical outcomes. Materials and Methods  Forty-nine primary and revision procedures were retrospectively analyzed for treatment outcomes, postoperative complications, functional hand scoring, and satisfaction rates postoperatively. Results  Thirty-eight patients were treated successfully with no postoperative contracture. There were three treatment failures and two graft failures, with two amputations within these failures. Paired pre- and postoperative Unité Rhumatologique des Affections de la Main scoring demonstrated significant improvement in hand function for primary procedures, with a mean satisfaction score of 7.7 out of 10. Conclusion  We have shown early graft review following dermofasciectomy and full-thickness skin grafting to be safe, allowing early mobilization and splinting, with our postoperative failure and complication rate being within published literature.     

Telmisartan in the Treatment of Cohen-Rosenthal Diabetic Hypertensive Rats: The Benefit of PPAR-γ Agonism

The antihypertensive and hypoglycemic effects of telmisartan, which has dual angiotensin II antagonist-PPAR-γ agonist properties, was studied in Cohen-Rosenthal Diabetic Hypertensive rats (CRDH), a model in which hypertension, insulin resistance, and diabetes co-exist. CRDH, Cohen-diabetic rats (CDR), and SHR received telmisartan (3 mg/kg/day in drinking water) for five months. Telmisartan significantly lowered systolic and diastolic BP in SHR and CRDH, independent of body weight, and remained fairly constant in controls throughout the experiment. Blood glucose levels fell rapidly in the treated animals and remained steady in controls. Results indicate that telmisartan is a prototype of a new approach to treating coexisting diabetes and hypertension.     

A prospective pilot study of circulating endothelial cells as a potential new biomarker in portal hypertension

Background/Aims: Peripheral circulating endothelial cells (CEC) have been proposed as a prognostic marker in cardiovascular diseases. Cirrhosis and portal hypertension are associated with vascular injury yet little is known about CEC count in these conditions. Therefore, we evaluated CEC count in patients with cirrhosis, and correlated it with markers of portal hypertension/disease severity. Patients/Methods: Fifteen patients with cirrhosis/portal hypertension and 15 matched controls were prospectively recruited for study participation. An automated rare cell analysis system was used to enumerate CEC from peripheral blood and correlated with clinical features. Results: Median CEC levels were significantly higher in patients with cirrhosis as compared with controls (median [interquartile range (IQR)]; cirrhosis: 73.7 cells/4 ml [53.7–140.3]; controls: 28.7 cells/4 ml [21–58.7]; P=0.021). Ratio of CEC to platelet count (CEC/PC) also distinguished patients with cirrhosis from controls (IQR; cirrhosis: 0.723 [0.396–1.672]; controls: 0.126 [0.103–0.333]; P<0.001). Receiver operator characteristic analysis revealed that CEC cut‐off of 42 cells/4 ml showed sensitivity of 87% and specificity of 74% for differentiating cirrhosis from controls (AUC: 0.74), while CEC/PC ratio at 0.21 showed sensitivity of 100% and specificity of 73% (AUC: 0.89). Furthermore, CEC/PC index was significantly elevated in patients with hepatic decompensation as defined by Child B/C (P<0.05). The intra‐ and interobserver variability correlation coefficients for CEC measurement were 0.9989 and 0.9986 respectively. Conclusion: Median CEC count and CEC/PC ratio are significantly elevated in patients with cirrhosis, with CEC/PC also increased in patients with decompensated cirrhosis. These data provide rationale for larger validation studies to assess if CEC may have prognostic utility in patients with cirrhosis and portal hypertension.     

S-Allyl-Mercapto-Captopril: A Novel Compound in the Treatment of Cohen-Rosenthal Diabetic Hypertensive Rats

J Clin Hypertens (Greenwich). 2010;12:451–455. ^©2010 Wiley Periodicals, Inc. S-allyl-mercapto-captopril (CPSSA) is a conjugate of captopril with allicin, an active principle in garlic with multiple beneficial actions on metabolic syndrome abnormalities, including weight preservation, observed by the authors in fructose-induced hypertensive hyperinsulinemic rats and in Koletsky rats. The aim of the study was to examine blood pressure (BP) and glucose levels in the Cohen-Rosenthal Diabetic Hypertensive (CRDH) model as well as to follow their weight preservation. CRDH rats (n=14) were fed the sugar-rich copper-free diet essential for the development of diabetes mellitus. Two months later BP and blood glucose levels were measured. CPSSA was diluted in drinking water and administered at a final dose of 53.5 mg/kg/d (n=8). Control rats (n=6) received no drug (vehicle group). In contrast to control group, CPSSA prevented progressive weight gain, without a detectable effect on food and water intake. CPSSA was effective in attenuating systolic and diastolic BP (P<0.01) as well as significantly reducing glucose levels (P<0.01). Control rats continued to gain weight, whereas the groups fed CPSSA did not. CPSSA was shown to have additional beneficial effects on improving BP and glucose level, as well as preserving weight gain. The authors conclude that the combined molecule CPSSA integrates the antihypertensive feature of both allicin and captopril, making it a potential antidiabetic and cardiovascular protective agent.     

The correlation between sperm cell morphology and fertilization after zona pellucida slitting in subfertile males

OBJECTIVE: This work was undertaken to evaluate the correlation between sperm cell morphology and fertilization after zona pellucida slitting in subfertile males. DESIGN: Twenty-two couples who failed at least one in vitro fertilization attempt because of lack of oocytes fertilization underwent a zona-slitting micromanipulative procedure. A total of 245 oocytes were retrieved and inseminated by three different modes: 151 oocytes underwent micromanipulation, 2 were damaged, and the remaining 149 inseminated by the husband's sperm (group A). Fifty-five oocytes were not manipulated and inseminated by the husband's sperm (group B), and 39 oocytes were not manipulated and inseminated by a donor sperm (group C). RESULTS: Fertilization rates were 26.8%, 5.5%, and 53.8% in groups A, B, and C, respectively, and differed significantly between group A and group B. The cleavage rates were lower for oocytes fertilized by the husband's sperm (48.6%) than that obtained by donor (90%), suggesting a sperm factor contributing to this phenomenon. The procedure was most efficient in patients with a total motile sperm count after preparation of greater than or equal to 5 million and with either normal sperm morphology or defects localized to the acrosome or tail region only. Sperm with nuclear morphological abnormalities demonstrated a marked reduction in fertilization potential. CONCLUSION: It is concluded that the zona-slitting technique enhances fertilization of severely subfertile sperm, and its efficacy is affected by sperm morphology and a threshold concentration of motile cells.     

McRoberts maneuver for the management of the aftercoming head in breech delivery.

A case report of breech delivery complicated by entrapment of the aftercoming head is presented. McRoberts maneuver was applied to facilitate the release of the head. It is suggested that the same theoretical basis that stands behind the use of McRoberts maneuver in shoulder dystocia might make it applicable as one of the maneuvers to release the aftercoming head in breech delivery.     

Granular cell tumor of the larynx: report of two pediatric cases.

Granular cell tumors are uncommon neoplasms of the head and neck that usually involve the tongue. The larynx is an atypical site of involvement in adults and a rare site in children. We report two cases of subglottic granular cell tumors, one in a 10-year-old boy and the other in a 6-year-old girl. Although both were initially misdiagnosed as having asthma, radiologic, laryngoscopic, and histologic evaluation of the obstructions eventually furnished the correct diagnosis. The patients were successfully treated by surgical excision of their subglottic masses. The history, presentation, pathologic findings, management, and prognosis of this rare pediatric laryngeal tumor are explored.
