Salmonella enterica Serovar Enteritidis Liver Abscess after Blunt Abdominal Trauma.

BACKGROUND: Salmonella enterica serovar Enteritidis is among the most reported serotypes of Salmonella species worldwide, but is rarely reported as the causative agent of a liver abscess. CASE REPORT: We present a patient with an abdominal blunt trauma. An initial abdominal computed tomography scan revealed a rupture of the right kidney and of the liver. Two days later, his physical state deteriorated and a new computed tomography scan was obtained. An extremely large 8-centimetre liver abscess was verified. Due to the unsatisfying response to antibiotic therapy and percutaneous drainage, we operated on the patient. An appendectomy, cholecystectomy and bisegmental liver resection were performed. An intraoperative swab from the abscess was positive for Salmonella enterica serovar Enteritidis. The patient was given intravenous ciprofloxacine. The post-operative course was complicated by a Coagulase-negative Staphylococcus infection of the wound, which improved with antibiotic therapy. CONCLUSION: Blunt abdominal trauma may initiate an unpredictable course of the disease in chronic Salmonella carriers.

GSK3ß and Gli3 play a role in activation of Hedgehog-Gli pathway in human colon cancer - Targeting GSK3ß downregulates the signaling pathway and reduces cell proliferation.

The role of Hedgehog-Gli (Hh-Gli) signaling in colon cancer tumorigenesis has not yet been completely elucidated. Here we provide strong evidence of Hh-Gli signaling involvement in survival of colon cancer cells, with the main trigger of activation being deregulated GSK3ß. Our clinical data reveals high expression levels of GSK3ß and Gli3 in human colon cancer tissue samples, with positive correlation between GSK3ß expression and DUKES' stage. Further experiments on colon cancer cell lines have shown that a deregulated GSK3ß upregulates Hh-Gli signaling and positively affects colon cancer cell survival. We show that inhibition of GSK3ß with lithium chloride enhances Gli3 processing into its repressor form, consequently downregulating Hh-Gli signaling, reducing cell proliferation and inducing cell death. Analysis of the molecular mechanisms revealed that lithium chloride enhances Gli3-SuFu-GSK3ß complex formation leading to more efficient Gli3 cleavage and Hh-Gli signaling downregulation. This work proposes that activation of the Hh-Gli signaling pathway in colon cancer cells occurs non-canonically via deregulated GSK3ß. Gli3 seems to be the main pathway effector, highlighting the activator potential of this transcription factor, which is highly dependent on GSK3ß function and fine tuning of the Gli3-SuFu-GSK3ß platform.

Thigh abscess as an extension of psoas abscess: the first manifestation of perforated appendiceal adenocarcinoma: case report.

A 65-year-old woman presented with a painful, swollen, red right thigh and the mild pain in the right abdomen without nausea, vomiting or diarrhoea that lasted for 1 week. Laboratory findings revealed elevated inflammatory markers. Computed tomography of the right thigh, abdomen and pelvis showed an abscess formation in the adductor muscles draining from the abscess that completely occupied the right retroperitoneum up to the diaphragm, dissecting downward through the inguinal canal. Appendix was enlarged with an appendicolith. Emergent exploratory laparotomy revealed a perforated appendix with psoas abscess. Pathohistological diagnosis revealed adenocarcinoma of the appendix. Thigh abscess is an uncommon condition with insidious clinical presentation. Therefore, early recognition and setting of the correct diagnosis enables adequate treatment avoiding additional complications and in some cases potential life-threatening conditions. When upper leg abscess is suspected or proven abdominal examination is mandatory.

Efficacy of sling procedures for treatment of female stress urinary incontinence.

The aim of this study was to determine the efficacy and surgical outcome of the sling procedures in stress incontinent women in comparison to conventional anterior colporrhaphy. Total of 56 patients with stress urinary incontinence (SUI) were treated with sling procedure between November 2011 and March 2013, 39/56 (69.6%) with suprapubic arc (SPARC) and 17/56 (30.4%) with MiniArc method. During the same period total of 49 patients with SUI were treated with traditional anterior colporrhaphy according to Bagovid method as the control group. All patients were prospectively clinically assessed over aperiod of 3, 6 and l2 months after surgery. The objective cure rate after the follow-up was 92.9% (52/56) in observed group of patients and 79.6% (39/49) in control group and improvement was occurred in rest of 5.4% (3/56) and 18.4% (9/49), respectively (p < 0.05). The overall complications rate was significantly lower in the observed group of patients than in the control group, 12.5% (7/56) vs. 28.6% (14/49), (p < 0.05). In the sling group was postoperatively noticed slightly higher rate of urinary incontinence, but in the colporrhaphy group was emphasized rate of urinary retention. Only one from the each group of patients failed the surgical procedure and required additional correction for SUI. The mean operating time for SPARC and MiniArc procedure was 19 +/- 7 and 9 +/- 5 minutes, respectively (p < 0.0001). Mean duration of hospitalization was significantly shorter in the sling group of patients (2.6 +/- 1.0, range 2-7) days than in the control group of (9.6 +/- 1.8, range 6-18), (p < 0.001 < 0.0001). According to presented results, sling is a highly effective method in patients with SUI with low incidence of perioperative complications, promising long-term results and high patient's satisfaction.

Hemoptysis as an early symptom of abdominal actinomycosis with thoracic extension ten years after cholecystectomy with retained gallstone.

BACKGROUND: Thoracoabdominal actinomycosis is rare, especially in the context of readily available medical facilities. METHODS: Case report and review of the literature. CASE REPORT: A 54-year-old male patient was admitted because of hemoptysis and a pulmonary infiltrate in the left lower lobe. His history was unremarkable except for chronic gastritis and an elective laparoscopic cholecystectomy performed 10 years earlier. Following persistent hemoptysis, elevated inflammatory markers, and a non-revealing bronchoscopy, a computed tomography scan of the thorax and upper abdomen revealed a tumor in the upper part of the left kidney spreading directly to the adjacent diaphragm and left lower lobe. Laparotomy revealed a granulomatous mass containing a gallstone, as well as orange granular content. The treatment involved surgical removal of the mass, splenectomy, excision of the infiltrated part of the left hemidiaphragm, and decortication of the left lower lobe. Because of a prolonged post-operative low-grade fever and radiologically confirmed encapsulation in the lingula, the patient was given ceftriaxone. Repeat bronchoscopy revealed Actinomyces meyeri. The initial antibiotic therapy was replaced with amoxicillin-clavulanic acid, after which the patient's health improved. CONCLUSION: Actinomycosis is still a highly intriguing disease, as initial symptoms often mislead clinicians. It is important to consider the disease whenever we are challenged diagnostically or when risk factors are present.

Operative complications and results of the "SPARC" procedure for stress urinary incontinence.

The aim of this study was to determine the efficacy and operative complications of the suprapubic arc (SPARC) procedure in stress incontinent women with and without previous anti-incontinence surgery. One-hundred and twenty-one patients with stress urinary incontinence (SUI) were treated with SPARC for correction of urethral hypermobility (N = 65) and intrinsic sphincter deficiency (N = 56) between August 2002 and February 2007. The long-term surgical results, operative complications (bladder injury, retropubic hematoma, de novo urgency and urinary infection) and patients' satisfaction were assessed. The overall complication rate was 9.9% (12/121). The perioperative complication rate was 1.7% including 2 urinary bladder injuries. Significant difference in the overall complications rate was detected between women with and without previous surgery (23/45, 51.1% vs. 6/108, 5.5%, chi2 = 49.89, P < 0.001). The overall postoperative complication rate was 8.3% (10/121) including 4 de novo urgencies, 4 urinary infections and 2 retropubic hematomas. There were 3 patients with postoperative urinary retention managed conservatively, without voiding difficulties on control visits. The objective cure rate after the follow-up was 86.8% (105/121). In patients with SUI and without preceding vaginal operations SPARC is a good method with low incidence of perioperative complications, promising long-term results and high patient satisfaction.
