Unexpected foreign body in the bladder of a spinal cord injured patient: A case report

Context: Bladder dysfunction is common in patients with spinal cord injuries. Clean intermittent catheterization is a preferred method of neurogenic bladder management among spinal cord injured patients. Some complications may occur due to the use of clean intermittent catheterization.

Findings: In this report, we presented a case with an unexpected foreign body detected in the bladder of a patient who used to perform clean intermittent catheterization for her neurogenic bladder management, to our knowledge, which has not been reported in the literature so far.

Conclusion/Clinical Relevance: In this case report, we want to emphasis the importance of different kind of foreign bodies remaining in the bladder during clean intermittent catheterization.     

Possible anti-metastatic effect of Iloprost in a patient with systemic sclerosis with lung cancer: a case study

Systemic Sclerosis (SSc) is a chronic disease of unknown etiology which affects the vascular system and connective tissue. A wide series of studies showed an increased prevalence of cancer in patients with SSc than the normal population. Prostacyclin (PGI2) is an endogenously produced element that is basically synthesized by arachiodonic acid through prostacyclin synthesis in vascular system endothelial cells. Iloprost is a stable analogue of PGI2 which is used in the treatment of pulmonary arterial hypertension (PAH). In a limited number of animal models, the anti-metastatic activity of PGI2 is observed. Herein, we report iloprost treatment of a 60-year-old-woman with SSc, who lately developed PAH as a complication of her disease and lung adenocarcinoma as a co-incidence simultaneously. These two mortal complications were both treated successfully with inhaled iloprost until her death due to gastrointestinal complications of SSc.     

Coexistent findings of renal glomerular disease with Hashimoto's thyroiditis

Aim and Background Hashimoto’s thyroiditis (HT) is a common autoimmune thyroid disease with a female preponderance. Renal involvement in HT is not uncommon. In the present study, we aimed to define the frequency and characteristics of the glomerular diseases associated with HT and further the understanding of any common pathogenesis between HT and glomerular disease. Materials and Methods We reviewed retrospectively 28 patients with HT who were referred to our Department because of unexplained haematuria, proteinuria or renal impairment from 2007 to 2011. Routine laboratory investigations including blood count, serum biochemistry, urinalysis and 24‐h urinary protein excretion were performed on all patients. Renal biopsy was performed in 20 patients with HT, and the specimens were examined by light microscopy and immunofluorescence staining. Results We detected four cases of focal segmental glomerulosclerosis (FSGS), four membranous glomerulonephritis (MGN), two minimal‐change disease (MCD), three immunoglobulin A nephritis (IgAN), three chronic glomerulonephritis (CGN) and one amyloidosis. In three patients, the renal biopsy findings were nonspecific. Daily urinary protein excretion and glomerular filtration rates were found to be independent of the level of thyroid hormone and thyroid‐specific autoantibodies. Conclusion Glomerular pathologies associated with HT are similar to those in the general population, the most common lesions being MGN, FSGS and IgA nephritis.     

The effect of antithyroid treatment on atrial conduction times in patients with subclinical hyperthyroidism

Background: Prolonged atrial conduction time measured by tissue Doppler imaging (TDI) has been associated with increased risk of atrial fibrillation. We aimed to evaluate the effect of subclinical hyperthyroidism (SH) and antithyroid treatment on atrial conduction time. Methods: A total of 30 patients with SH (26 females; mean age 34.8 ± 8.5 years) and 30 age- and gender-matched controls were included. Using TDI, atrial conduction time was measured from the lateral mitral annulus, septal mitral annulus, and lateral tricuspid annulus. Intra- and interatrial conduction delay were calculated. TDI and thyroid hormone levels were studied at the time of enrollment and after achievement of euthyroid state with propylthiouracil treatment. Patients were followed for 14 ± 3 weeks. Results: Atrial conduction time at the lateral and septal mitral annulus were significantly higher in patients with SH compared to controls. Both inter-, right, and left intraatrial electromechanical delay were prolonged in patients with SH compared to control subjects (21.3 ± 6.1 vs. 13.9 ± 4.3, P < 0.001 and 4.2 ± 3.5 vs. 2.3 ± 1.9, P = 0.014 and 17.1 ± 6.0 vs. 11.6 ± 3.8, P < 0.001, respectively). After achievement of euthyroid state, inter- and left intraatrial electromechanical delay were significantly decreased compared to baseline values and approximated to the values of the control group (P < 0.001). Conclusion: SH is associated with prolonged atrial conduction time. After achievement of euthyroid state, decrement in atrial conduction time may reveal how the antithyroid treatment may prevent the development of atrial fibrillation in these patients.     

The relationship of epicardial adipose tissue thickness to clinical and biochemical features in women with polycystic ovary syndrome

The amount of epicardial adipose tissue (EAT), a component of body visceral adiposity, has been linked to the presence and severity of cardiovascular disease through multiple mechanisms. Polycystic ovary syndrome (PCOS) is characterized by insulin resistance and subclinical inflammation, which participate in the mechanism of atherosclerosis. We searched if the patients with PCOS have increased EAT thickness (EATT), along with its relation to the measures of adiposity and insulin sensitivity. A total of 41 subjects with PCOS and 46 age and body mass index (BMI) matched healthy controls were enrolled. EAT was measured by echocardiography above the free wall of the right ventricle. Insulin resistance was assessed by homeostasis model assessment of insulin resistance (HOMA-IR) formula, and plasma adiponectin level was measured by ELISA. Compared to healthy controls EATT and HOMA-IR score were significantly higher (p=0.0001 for both) while plasma adiponectin concentration was significantly lower (p=0.048) in women with PCOS. EATT correlated positively with total cholesterol, triglyceride, luteinizing hormone (LH) and negatively with sex hormon binding globuline (p<0.05 for all), whereas it displayed no correlation to plasma adiponectin level (p=0.924). Triglyceride level was the significant determinant of EATT in logistic regression analysis (p=0.035). Thickness of the EAT is increased in patients with PCOS in conjunction with hyperandrogenity. Prospective studies are required to identify the relation of EAT and cardiovascular risk in patients with PCOS.     

Clonal distribution of vancomycin-resistant Enterococcus faecium in Turkey and the new singleton ST733

BackgroundThe aim of this study was to provide information about the spread and characteristics of the vancomycin‐resistant Enterococcus faecium isolates (VREfm) in Turkey.MethodsSeventy‐one nonduplicate consecutive isolates of VREfm were obtained from various clinical specimens of inpatients treated at university or training hospitals in seven regions of Turkey. Further characteristics included antibiotic susceptibility testing, pulsed‐field gel electrophoresis (PFGE) of SmaI‐digested genomic DNA, and multilocus sequence typing (MLST) of selected isolates. The presence of vancomycin resistance and virulence genes (esp and hyl) was investigated by polymerase chain reaction (PCR).ResultsAll VREfm isolates had MICs to vancomycin of ≥32 mg/L and contained the vanA gene. The presence of esp gene was identified in 64 and hyl in eight VREfm isolates. All VREfm showed the multiresistance phenotype, including ampicillin (99%), penicillin (99%), imipenem (99%), ciprofloxacin (87%), moxifloxacin (87%), erythromycin (97%), streptomycin (86%), gentamicin (82%), tetracycline (70%), and teicoplanin (99%). All were susceptible to tigecycline while quinupristin‐dalfopristin (97%) and linezolid (93%) were the most active other agents. Analysis of the PFGE profiles showed that 53 (74.6%) VREfm isolates shared a similar electrophoretic profile, designed as type 1, and were closely related (>85%). The sequence type was identified by MLST in 44 VRE isolates with unrelated or closely related PFGE patterns. MLST revealed that nosocomial spread of VREfm resulted from dissemination of lineage C1 E faecium clones. Sequence types ST78, ST203, and ST117 were the most frequently isolated. This is the first report of ST733 around the world.ConclusionsLineage C1 clones are disseminated among clinical VREfm isolates in seven different regions in Turkey. Regarding VREfm isolates, the worldwide epidemic strains are in circulation in Turkey.     

Surgical Interventions for Late Complications of Arteriovenous Fistulas

Our aim was to determine the most effective surgical treatment for arteriovenous fistula (AVF) complications after all other methods of salvage have failed. We evaluated 110 patients for 139 complications that occurred after the initial AVF placement and for whom surgical intervention was the last hope for retaining fistula access. Vascular steal syndrome and venous hypertension were the most common complications seen in our patients. The anastomoses of 17 of the vascular steal syndrome cases were narrowed either by stitches or by a polytetrafluoroethylene graft. The second most performed revision surgery was excision of the aneurysm and repair with primary suturing, followed by excision of the aneurysm and interposition grafting. Successful surgical outcomes were achieved in 111 of 139 procedures after revision surgery without constructing a new AVF. AVF salvage surgery is of paramount importance in order to increase the patency rate, which prolongs survival and increases the patient''s quality of life.Key words: Arteriovenous fistula, Complications, Hemodialysis, Vascular accessBecause survival rates in patients with end-stage renal disease have been rising because of developments in treatment procedures, the importance of sustained vascular access for hemodialysis has increased.¹Many late complications, such as (1) thrombosis, (2) venous hypertension, (3) aneurysm/pseudoaneurysm formation, (4) hemorrhage, (5) vascular steal syndrome (VSS), (6) stenosis, and (7) heart failure may occur following arteriovenous fistula (AVF) surgery.^1,2 These may cause dysfunction of the AVF and limit the efficiency of hemodialysis.Our aim in this retrospective analysis is to present our experience in the surgical treatment of AVF complications in patients for whom all other conservative treatment methods of salvage have failed. These include radiologic interventions, such as covered stent; coil embolization; application of thrombin or percutaneous transluminal angioplasty balloon dilatation; thromboaspiration; and thrombolysis. Our study contributes to the literature because data on successful surgical salvage techniques for AVFs are limited, despite the relative high frequency of documented AVF complications. Our study focuses on surgical solutions, in particular highlighting minor factors that can increase the success of surgical interventions for compromised AVFs. For this study we examined the clinical presentations and surgical techniques for treating these complications and postintervention outcomes.     

Dexamethasone effects on vascular flow and organ injury in septic mice

Background

To demonstrate the effects of low-dose dexamethasone treatment on mesenteric artery blood flow, oxidative injury, vascular reactivity, and survival in Swiss albino mice with intra-abdominal polymicrobial sepsis accomplished by cecal ligation and puncture (CLP).

Methods

Mice were allocated to CLP + saline, CLP + dexamethasone, sham + saline, and sham + dexamethasone subgroups to evaluate blood flow, organ injury, and vascular response to consecutive phenylephrine administrations at 24, 48, and 72 h. Survival rates were also evaluated in a different group of mice. Dexamethasone (1 mg/kg/d) and saline (4 mL/kg/d) were administered intraperitoneally to mice 2 h after CLP or sham procedure, whichever appropriate, and repeated once a day until evaluation time at 48 and 72 h. Relaparotomy was performed at the concerned time and mesenteric blood flow was measured, and liver, lung, and peritoneum samples were obtained. Alteration in mesenteric blood flow response to intravenous phenylephrine injections was recorded at the related time intervals in different mice groups. Survival group was followed up by 7-d administration of dexamethasone or saline for 18 d.

Results

The significant fall in mesenteric blood flow after CLP ameliorated with dexamethasone treatment at 48 and 72 h. Dexamethasone also diminished the malonyl dialdehyde level, which is an indicator of organ injury raised after CLP, at 24 h in liver, lung, and peritoneum samples. Dexamethasone therapy has significantly enhanced the vascular response to phenylephrine injections at all doses; however, no change was observed in survival rates.

Conclusions

Low-dose dexamethasone has beneficial effects on mesenteric blood flow and organ injury in experimental sepsis models.
