Distally-based peroneus brevis muscle flap: A successful way of reconstructing lateral soft tissue defects of the ankle

Sixteen distally-based peroneus brevis muscle flaps were used to cover soft tissue defects in the lateral side of the ankle. The defect in 13 cases was on the lateral malleolus, in two on the lateral side of the calcaneus, and in one case in the Achilles tendon. The patients were all followed up until full recovery (mean 7.6 months, range 1.5–22 months). One flap failed to cover the defect and was replaced with a microvascular latissimus dorsi flap. In three cases minor revision and new skin grafting of the distal end of the flap was necessary. In 15 of the 16 patients the distally-based peroneus brevis muscle was successful in covering the lateral defect in the ankle. The technique of harvesting a flap is reliable, fast, and the overall success of the flap is good. The flap is particularly suitable for covering small or moderate sized defects on the lateral malleolus.     

Impact of multiple traumatic experiences on the persistence of depressive symptoms – a population-based study

The objective of this population-based study was to determine whether traumatic experiences in general, and multiple traumatic experiences in particular, are associated with persistent self-rated depressive symptoms in adult Finnish subjects over 2?years of follow-up. The study sample included 1405 subjects aged 25–64?years. Subjects (n=217) who were depressed both at baseline in 1999 and on follow-up 2?years later in 2001 (having persistent depressive symptoms) were compared with subjects (n=987) having no depressive symptoms either at baseline or on follow-up. All six categories of traumatic experiences (wartime experience, natural disaster, life-threatening accident, victim of violent crime, domestic violence and childhood sexual abuse) pertained to the respondents’ whole life span. Odds ratios, adjusted for significant covariates, were obtained from multiple logistic regression models that estimated the likelihood of persistent depressive symptoms in different trauma categories. Persistent depressive symptoms had a significant positive graded relationship with the number of traumatic experiences. The adjusted odds of persistent depression was 6.05 (95% CI 1.76–20.7) for men and 6.99 (95% CI 2.69–18.2) for women in those with three or more traumatic experiences compared with those with no such experiences at all. Multiple traumatic experiences substantially increase the likelihood of persistent depressive symptoms. Mental health intervention, as early as possible, may serve to prevent the chronicity of depressive reactions among victims of multiple traumas.     

Maternal smoking during pregnancy and offspring psychiatric disorder: a longitudinal birth cohort study

Background

There is evidence that prenatal stress and smoking during pregnancy both independently increase the risk of offspring psychopathology. Here we examine whether increased levels of self-reported stress is associated with increased smoking in a population of pregnant women, and whether prenatal smoking is associated with offspring psychiatric diagnoses independent of prenatal stress exposure.

Method

Using a longitudinal birth cohort, we used ordered logistic regressions to examine associations between maternal stress and smoking during pregnancy. We then used logistic regression analyses to examine associations between prenatal smoking and later offspring psychiatric disorders.

Results

A dose–response relationship was found between maternally reported stress and smoking during pregnancy. Pregnant women reporting severe stress were more likely to smoke compared to both the moderate stress and no stress groups, and those reporting moderate stress were significantly more likely to smoke compared to the no stress group. Smoking more than 5 cigarettes daily during pregnancy increased the risk of offspring personality disorder (OR 3.08, 95% CI 1.60–5.94) as well as developing any Axis 1 psychiatric disorder, inclusive of mood, anxiety and psychotic disorders (OR 1.45, 95% CI 1.04–2.04). After adjusting for parental psychiatric history and maternal self-reported stress during pregnancy, associations between smoking more than 5 cigarettes daily when pregnancy and offspring personality (OR 2.58 95% CI 1.32–5.06) disorder remained.

Conclusion

Exposure to cigarette smoking during gestation could impact a child’s mental health. Smoking during pregnancy is a prime target for preventative interventions as unlike most other environmental risk factors, it is very amenable to change.

     

Salbutamol‐induced Decrease in Augmentation Index is Related to the Parallel Increase in Heart Rate

The change in augmentation index following salbutamol inhalation has been applied to evaluate endothelial function. We examined the contribution of salbutamol‐induced increase in heart rate to the observed decrease in augmentation index. Haemodynamics were recorded using whole‐body impedance cardiography and continuous pulse wave analysis from tonometric radial blood pressure. All subjects (n = 335, mean age 46, body mass index 26, 48% men) were without medications with cardiovascular influences. The effects of salbutamol inhalation (0.4 mg) versus the endothelium‐independent agent nitroglycerin resoriblet (0.25 mg) were examined during passive head‐up tilt, as the haemodynamic influences of these compounds depend on body position. Salbutamol decreased augmentation index by ~3‐4% units in supine and upright positions. Although salbutamol moderately increased cardiac index (+4.5%) and decreased systemic vascular resistance (?8.5%), the significant haemodynamic explanatory factors for decreased augmentation index in multivariate analysis were increased supine heart rate, and increased upright heart rate and decreased ejection duration (p < 0.001 for all, r² = 0.36–0.37). Sublingual nitroglycerin decreased supine and upright augmentation index by ~15% units and ~23% units, respectively. The haemodynamic explanatory factors for these changes in multivariate analysis were increased heart rate, reduced ejection duration and reduced systemic vascular resistance (p ≤ 0.021 for all, r² = 0.22–0.34). In conclusion, the lowering influence of salbutamol on augmentation index may be largely explained by increased heart rate, suggesting that this effect may not predominantly reflect endothelial function.     

Case for staged thyroidectomy

Recent modifications in the management of well‐differentiated thyroid cancer have resulted in significant alterations in clinical approach. Utilizing a series of preoperative and postoperative risk factors involving both the patient and the disease pathology, we offer the term “staged thyroidectomy” to help organize these risk factors for patients and the endocrine team to optimize management. This approach is intended to incorporate our latest nuanced understanding of certain endocrine pathology and may serve to optimize patient outcomes.     

Repeated metal ion measurements in patients with high risk metal-on-metal hip replacement

Purpose

Conventional follow-up methods are not sufficient to identify adverse soft tissue reactions in patients with metal-on-metal hip replacements. The national guidelines regarding metal ion measurements are debatable. The aims of our study were to investigate (1) if there is a clinically significant change in whole blood (WB) cobalt (Co) or chrome (Cr) levels in repeated WB assessment in patients operated on with ASR hip replacements, and (2) what proportion of patients has WB Co or Cr level below the previously established safe upper limits (SUL) in the repeated WB metal ion assessment.

Methods

We identified all patients (n = 254) with unilateral ASR implants who had second blood sample taken eight to 16 months after the first.

Results

WB Co and Cr levels remained below SUL and within their initial values during a mean one-year measurement interval in the majority of patients with a high risk HR device. In contrast to this, 50 % of patients with THRs had metal ion levels exceeding the SUL in the first measurement. WB Co values significantly increased over the measurement interval in the THR group.

Conclusion

In patients with a high risk HR, repeated metal ion measurement did not provide useful information for clinical decision-making. In patients with a LD MoM THR repeated measurements revealed a large number of patients with metal ion levels exceeding SUL and might thus be clinically beneficial.
