[Impact of maternal risky behaviors on the behaviors of children born to adolescent and young mothers].

Objective: To examine the impact of maternal risky behaviors on the behaviors of children born to adolescent and young mothers. Methods: Adolescents and young Chinese mothers were recruited from an integrated young mother supportive program in Hong Kong between January and June 2015. Eligible mothers were asked to complete a questionnaire on their sociodemographic characteristics and history of risky behavior as well as their children's behaviors. Multiple regression analyses were conducted to explore the association between maternal risky behaviors and their children's behaviors. Results: Among 201 respondents, there were 187 (93.0%) ex-drinkers, 136 (67.7%) ex-smokers, and 83 (41.3%) ex-addicts. Compared to the reference group, children of mothers with drug use behaviors were more likely to have abnormal SDQ total difficulties scores (odds ratio 2.60, P=0.01), those of ex-drinking mothers had more behavioral difficulties and more conduct problems (B=3.82 and 1.37, P both=0.01) and those of ex-smoking mothers had more conduct problems (B=0.74, P=0.01) after adjustment for confounders. Children of active drug-taking mothers also had more emotional symptoms (B=1.77, P=0.04) and hyperactivity/inattention problems (B=2.14, P=0.03). Conclusion: The history of mother's risky behavior was significantly associated with the behavioral problems of the children.

High serum lactate as an adjunct in the early prediction of anastomotic leak following oesophagectomy.

BACKGROUND: Anastomotic leak (AL) following oesophagectomy carries a high mortality and morbidity. Early detection and intervention is required for a successful outcome. We have examined the role of a high postoperative serum lactate in predicting which patients are at risk of developing an anastomotic leak(AL). MATERIALS AND METHODS: All patients who underwent transthoracic oesophagectomy over a 3-year period were identified from a prospectively collected database. Medical records were reviewed to identify the highest serum lactate recorded from blood gas analysis over each 24hr post-operative period. Patients who underwent transhiatal and left thoraco-abdominal oesophagectomies were excluded. Patients who developed a chyle leak were excluded. RESULTS: Of a total of 136 oesophagectomies included for analysis, 18 developed an AL (13.2%). Of these patients, 10 underwent thoracoscopic oesophageal mobilization with cervical anastomosis and the rest an Ivor Lewis procedure. Predictive factors for AL included neoadjuvant chemotherapy (15/18 83.3% vs 55/118 46.6% p = 0.0046) and number of positive lymph nodes (mean 4.2 vs control mean 2.3 p = 0.045). Overall net fluid balance was comparable between the 2 groups, although AL patients received slightly more fluid on Day 3. High lactate levels on days 1-3 were associated with an AL. Using a Day 2 lactate of 1.7 mmol/L, the sensitivity of predicting AL was 72% and specificity 88%. The mean lag time using existing diagnostic modalities was 7.9 days. CONCLUSION: A serum lactate of >1.7 mmol/l on day 2 should raise the possibility of a potential AL. Such patients should be selected for more intensive monitoring, optimization and selective gastroscopy.

Rectal perforation secondary to transanal haemorrhoidal dearterialisation.

Haemorrhoidal artery ligation has now been established as a treatment modality for symptomatic haemorrhoids. We report a case of a fit 44-year-old male who underwent the procedure as a day case, who subsequently developed pelvic sepsis due to rectal perforation. This case is the first report of a potentially life-threatening complication resulting from this procedure, which has a previously excellent safety profile.

Factors affecting the healing of the perineum following surgery.

INTRODUCTION: The aim of this study was to establish patient and procedural factors associated with the development of an unhealed perineum in patients undergoing a proctectomy or excision of an ileoanal pouch. METHODS: A review of 194 case notes for procedures performed between 1997 and 2009 was carried out. All patients had at least 12 months' follow-up. Univariate and multivariate analyses were performed in 16 parameters. For those patients who developed an unhealed perineum, Cox regression analysis was performed to establish healing over a 12-month period. RESULTS: Two hundred patients were included in the study, of which six had unknown wound status and were subsequently excluded. This left 194 study patients. Of these, 86 (44%) achieved primary wound healing with a fully healed perineum and 108 (56%) experienced primary wound failure. With reference to the latter, 63 (58%) healed by 12 months. Comparing patients with an initially intact perineum with those with initial wound failure showed pre-existing sepsis was highly relevant (odds ratio: 4.32, 95% confidence interval [CI]: 2.16-8.62, p<0.001). In patients who had an unhealed perineum initially, perineal sepsis and surgical treatment were both significantly associated with time to healing (hazard ratio [HR]: 0.54, 95% CI: 0.31-0.93, p=0.03; and HR: 0.42, 95% CI: 0.21-0.84, p=0.01). CONCLUSIONS: The presence of pre-existing perineal sepsis is associated with an unhealed perineum following proctectomy in inflammatory bowel disease (IBD) and non-IBD surgery. Further studies are indicated to establish perineal sepsis as a causative factor.

Anti-Saccharomyces cerevisiae antibodies status is associated with oral involvement and disease severity in Crohn disease.

OBJECTIVES: To determine anti-Saccharomyces cerevisiae antibodies (ASCA) status and its relation to disease phenotype in patients with inflammatory bowel disease (IBD). PATIENTS AND METHODS: A total of 301 Scottish patients with early-onset IBD-197 Crohn disease (CD), 76 ulcerative colitis (UC), 28 indeterminate colitis (IC)-and 78 healthy control individuals were studied. ASCA status (IgA, IgG) was determined by enzyme-linked immunosorbent assay. ASCA status was then analyzed in relation to CD phenotype. RESULTS: Patients with CD had a higher prevalence of ASCA than patients with UC and healthy controls: 82/197 versus 12/76, odds ratio (OR) 3.80 (1.93-7.50) and 82/197 versus 6/78, OR 8.56 (3.55-20.62), respectively. Univariate analysis showed that positive ASCA status was associated with oral CD (17/25 vs 59/153, OR 3.39 [1.38-8.34]), perianal CD (39/77 vs 38/108, OR 1.89 [1.04-3.44]) and the presence of granulomata (63/132 vs 15/52, OR 2.25 [1.13-4.48]) and also with markers of disease severity: raised C-reactive protein (44/90 vs 12/49, OR 2.95[1.36-6.37]), hypoalbuminemia (44/85 vs 20/74, OR 2.28[1.19-4.37]), and surgery (27/49 vs 54/147, OR 2.11 [1.10-4.06]). From multivariate analysis, the presence of oral disease (adjusted P = 0.001, OR 22.22 [3.41-142.86]) and hypoalbuminemia (adjusted P = 0.01, OR 4.78 [1.40-16.39]) was found to be independently associated with ASCA status. No association was demonstrated between ASCA and IBD candidate genes. CONCLUSIONS: Patients with CD had a higher prevalence of ASCA than did other patients with IBD. ASCA status described patients with CD who had a specific phenotype, showing an association with markers of disease severity and oral CD involvement.

A comparison of the sensitivity of APTT reagents to the effects of enoxaparin, a low-molecular weight heparin.

Low-molecular weight heparin (LMWH) is the product of enzymatic or chemical degradation of unfractionated heparin (UFH). It has been found to have better bio-availibility, more predictable dose response and can be used as an alternative to UFH for prophylaxis and treatment of thrombotic disorders. It is claimed that no laboratory monitoring is necessary for LMWH therapy; however, for the aged, renal impaired, obese or grossly underweight, monitoring of dose effect with anti-Xa assay is recommended. The activated partial thromboplastin time (APTT), which is the test of choice for UFH monitoring, is believed to be insensitive to the effect of LMWH. The sensitivity of the APTT to heparin lies in the APTT reagent used. In this study, eight different APTT reagents were used to compare the APTT with anti-Xa activity in ex vivo plasma from patients who were on enoxaparin (LMWH, Clexane) therapy. It was found that, as with UFH, APTT reagents show variable sensitivity to LMWH. The APTTs from all eight reagents were found to have a linear relationship to anti-Xa activity. The APTT results using three of the reagents gave an indication of the use of LMWH therapy. It was also found that patients who were lupus anticoagulant (LA)-positive had much more prolonged APTTs when on LMWH therapy; however, a linear correlation between APTT and anti-Xa was not present in these patients.
