Lipid peroxidation and liver damage in double and simple common bile duct ligation models in male Sprague-Dawley rats

AIMS

Bacterial translocation, defined as the presence of living bacteria or bacterial fragments in both mesenteric lymph nodes or systemic circulation, can cause a severe inflammatory reaction in patients with cirrhosis. This study aimed to compare lipid peroxidation associated with liver damage in different experimental models of bile duct ligation: proximal double ligation and transection versus proximal simple ligation versus sham.

MATERIALS AND METHODS

Sixty-two male rats underwent one of three bile duct surgical interventions: proximal double ligation and transection (n = 22); proximal simple ligation (n = 19); or sham operation (n = 21). We performed microbiological culture of mesenteric lymph nodes; portal and cava blood, spleen and liver cultures; and histological analysis of liver parenchyma. Samples of blood and liver were obtained at laparotomy for malondialdehyde quantification.

KEY FINDINGS

Serum malondialdehyde levels were significantly higher in simple ligature animals (3.7 nmol/mg, standard deviation [SD] 2.1) compared to controls (1.6 nmol/mg SD 0.5; p = 0.001) or double ligature (0.3 nmol/mg SD 0.3; p = 0.001). Liver malondialdehyde levels were significantly higher in animals subjected to double ligation vs controls (9.0 nmol/mg SD 2.8 vs. 1.7 nmol/mg SD 1.0; p = 0.0007) and simple ligature (2.9 nmol/mg SD 2.0; p = 0.0001). Overall incidence of bacterial translocation was similar in simple and double ligatures (22.2 % and 21 % respectively), and significantly higher than in controls.

SIGNIFICANCE

the type of bile duct ligation influences the type and localization of lipid peroxidation, but does not influence the development of bacterial translocation.

Genito Pelvic Pain/Penetration Disorder (GPPPD) in Spanish Women-Clinical Approach in Primary Health Care: Review and Meta-Analysis

Sexuality is a component of great relevance in humans. Sexual disorders are a major public health problem representing a high prevalence in the general population. DSM-5 genito-pelvic pain/penetration disorder (GPPPD) includes dyspareunia and vaginismus (DSM-IV-TR). To assess the importance of research on these disorders in Spain, we evaluated the Spanish scientific publications of primary and community care. The objective was to quantify the magnitude of the publications of GPPPD in Spanish women in primary and community care. For this, we used the method of conducting a systematic review and meta-analysis of studies evaluating GPPPD. As main results, of the 551 items found, we selected 11 studies that met the inclusion criteria. In primary care in Spain, one in nine women has these disorders; the percentage of women with GPPPD in this study (raw data) was 11.23% (95% CI: 0-29%) (vaginismus 5%; penetration pain 8.33%; dyspareunia 16.45%). These percentages can differ of those from other countries, and they are at the top of the data of the European countries (9-11.9%). There is much variability in the studies found in the world with respect to the prevalence of these health problems.

Sexuality, Quality of Life, Anxiety, Depression, and Anger in Patients with Anal Fissure. A Case-Control Study

Anal fissures (AFs) are lesions located in the lower anal canal. They can be primary (chronic or acute) or secondary to a basic disease. There is high comorbidity of depression and anxiety in patients with chronic AF, with poorer quality of life (QoL) and sexual function. This is a case–control study carried out in the San Juan Hospital (Alicante, Spain). Sixty-seven participants were included in the study, including 35 cases and 32 controls: 36 males and 31 females. This study aims to investigate the association of presenting AFs with sexuality, quality of life, anxiety, depression, and anger. The instruments used were the Spanish validated versions of the validated original selected questionnaires. These instruments were used to assess health-related quality of life, anxiety, anger, depression, and sexual function. Results show higher values in cases than in controls with statistical significance in anxiety state and trait; anxiety and depression; bodily pain, general health, and vitality; and 10 of the 12 anger factors. Higher values in controls than in cases with statistical significance in sexuality and many of the QoL factors were found. Addressing these issues in AF surgical patients would be beneficial for their clinical assessment and intervention.

Validation of the Center of Applied Psychology Female Sexuality Questionnaire (CAPFS-Q)

Instruments for the measurement of human sexuality include self-report measures used to assess sexual functioning, but many of them have not yet been validated. The Center of Applied Psychology Female Sexual Questionnaire (CAPFS-Q) is an original self-report instrument. It has been developed for the study of sexuality in specific non-clinical populations, such as female university students of Medicine and other Health Sciences. The CAPFS-Q includes 26 items, organized as follows: sociodemographic and relevant data (four items); aspects of sexual relations with partner (five items); sexual practices (12 from 13 items); and dysfunctional aspects of sexual relations (four items). CAPFS-Q validity and reliability were examined in a sample of Spanish female university students of Health Sciences. Exploratory and confirmatory factor analysis (FA) showed a four-factor structure which explained 71.6% of the variance. This initial version of the CAPFS-Q is a reliable measure of women's sexual behavior, with a dimensionality that replicates the initial theoretical content and with adequate indicators of internal consistency, validity, and test-retest reliability. It is easy to administer and to complete.

[Tratamiento ambulatorio de la diverticulitis aguda no complicada. Análisis de nuestra experiencia]

Objective

Analyze the safety and efficacy of the outpatient treatment of uncomplicated acute diverticulitis and a costs analysis.

Method

We conducted a prospective, non-randomized study between June 2014 and June 2017. We included all patients diagnosed of uncomplicated acute diverticulitis based on clinical and abdominal computed tomography scan in the Emergency Department of the University Hospital San Juan de Alicante (Spain). Outpatient treatment consisted of oral antibiotics for 7 days (amoxicillin-clavulanate or ciprofloxacin and metronidazole in patients with betalactamic allergy), liquid diet for 72 h and analgesics. Costs were evaluated according to the Law of Rates of Valencian Community.

Results

Ninety patients were included, 49 females and 41 males with a median age of 56 years. Success rate was 95.5% (n = 86) requiring hospital admission 4 patients (4.5%). Antibiotic treatment was amoxicillin-clavulanate in 82 patients (91.1%) and ciprofloxacin and metronidazole in 8 (8.9%). Cost savings per patient was approximately 1985 € comparing with hypothetically all inpatient treatment.

Conclusions

Outpatient treatment of uncomplicated acute diverticulitis can be performed successfully in most patients allowing an important cost savings.

Microbiologic Analysis of Complicated and Uncomplicated Acute Appendicitis

BACKGROUND

Microbiologic studies suggest that complicated (CAA) and uncomplicated (UAA) acute appendicitis are different entities. Routine peritoneal fluid cultures continue to be controversially related to a low positive rate, found mainly in UAA; to isolation of typical micro-organisms with expected susceptibilities; and to a community-acquired intra-abdominal infection. The aim of this study was to describe microbiologic isolates in CAA and UAA and the usefulness of peritoneal fluid cultures to determine the susceptibilities to our antibiotic therapy guidelines.

METHODS

This study was a retrospective review of a prospective database collected at University San Juan Hospital (Spain) between June 2014 and June 2017. Complicated acute appendicitis was defined as gangrenous or perforated, whereas UAA was defined as phegmonous or suppurative. Our antibiotic recommendations are amoxicillin-clavulanic acid and in patients with β-lactam allergies, metronidazole plus aztreonam, and an aminoglycoside (gentamicin or tobramycin). Microbiologic cultures were performed in 264 patients, 157 with a CAA and 107 with a UAA.

RESULTS

The positive culture rate was significantly higher in CAA (59%) than in UAA (24.3%). Gram-positive cocci (51.6% CAA; 23.1% UAA), including Streptococcus constellatus (29% CAA; 3.8% UAA), and anaerobes (67.7% CAA; 42.3% UAA) were significantly more common in CAA. The rates of antibiotic resistance were amoxicillin-clavulanic acid 14% (17.2% CAA; 3.8% UAA), gentamicin or tobramycin 8.4% (9.7% CAA; 3.8% UAA), ciprofloxacin 5.9% (6.5% CAA; 3.8% UAA), and ertapenem 10.9% (14% CAA; 0 UAA).

CONCLUSIONS

The culture-positive rate was higher in CAA, with different isolates and susceptibilities than in UAA, identifying a higher frequency of gram-positive cocci (including S. constellatus) and anaerobes. We recommend obtaining peritoneal fluid cultures in CAA, which frequently will lead to a change in the antimicrobial drug therapy guidelines, creating specific recommendations in AA.

[Gallstone ileus, an uncommon cause of bowel obstruction]

Gallstone ileus is a rare complication of cholelithiasis. It is characterized by bowel obstruction secondary to gallstone impaction at some point of the gastrointestinal tract due to the existence of a bilioenteric fistula. The aim of this analysis was to evaluate our experience through a retrospective study, covering a 12-year period. It included 14 cases (10 women and 4 men) with a median age of 81 years; 11 of the patients had comorbidities. The main analytic alteration was an increase in urea (median 79mg/dl). Diagnosis was confirmed through abdominal computed tomography in 10 cases and plain abdominal x-ray in 4. The stone was located in the jejunum in 6 cases, the ileum in 6, and the sigmoid colon in one; the mean stone size was 3cm. There were 11 cases of cholecystoduodenal fistula, one case of cholecystocolonic fistula, and one idiopathic fistula. Two patients died, including the patient that did not undergo surgery.
