RESUMEN
BACKGROUND: Depression and obesity are significant health concerns currently facing adolescents worldwide. This paper investigates the associations between obesity and related risk behaviours and depressive symptomatology in an Australian adolescent population. METHODS: Data from the Australian Capital Territory It's Your Move project, an Australian community-based intervention project were used. In 2012, 800 students (440 females, 360 males) aged 11-14â years (M=13.11â years, SD=0.62â years), from 6 secondary schools were weighed and measured and completed a questionnaire which included physical activity, sedentary behaviour and dietary intake. Weight status was defined by WHO criteria. A cut-off score ≥10 on the Short Mood and Feelings Questionnaire indicated symptomatic depression. Logistic regression was used to test associations. RESULTS: After controlling for potential confounders, results showed significantly higher odds of depressive symptomatology in males (OR=1.22, p<0.05) and females (OR=1.12, p<0.05) who exceeded guidelines for daily screen-time leisure sedentary activities. Higher odds of depressive symptoms were seen in females who consumed greater amounts of sweet drink (OR=1.18, p<0.05), compared to lower female consumers of sweet drinks, and males who were overweight/obese also had greater odds of depressive symptoms (OR=1.83, p<0.05) compared to male normal weight adolescents. CONCLUSIONS: This study demonstrates the associations between obesogenic risks and depression in adolescents. Further research should explore the direction of these associations and identify common determinants of obesity and depression. Mental health outcomes need to be included in the rationale and evaluation for diet and activity interventions.

Adolescence is a transitional life phase that is associated with heightened risk for two major health conditions - obesity and mental health problems. Given the established comorbidity of obesity and depression, one avenue that warrants further exploration is the association between obesogenic risk and obesity in the expression and maintenance of depressive symptoms. The aim of the current systematic review was to identify and evaluate the empirical literature reporting the relationships between obesogenic risk factors (physical activity, sedentary behaviour, diet and weight status) and depression in adolescents. A search of five databases for studies published over the last decade found 24 studies eligible for review. Relationships were found between lack of physical exercise, heightened sedentary behaviour, poor diet quality, obese or overweight and depression in adolescence. However, the finding that obesogenic risk factors are associated with poor adolescent mental health should be interpreted with caution as data typically come from non-representative samples with less than optimal study design and methodology.

AIMS: Awareness of hereditary breast and ovarian cancer in both the general public and the medical profession is increasing. Individuals who may be at risk on the basis of a family history are requesting risk determination and appropriate management in a variety of settings. Risk determination relies largely on pedigree analysis and epidemiological data. METHODS: We describe five individuals presenting in the family cancer or genetic counselling clinic where a factitious family or personal history led to erroneous risk estimation. Common factors in these families are a history of benign breast disease, poor communication within families, long survival with early onset or bilateral disease, a lack of detailed knowledge of the illness and treatment in close relatives and inconsistencies in the history in repeated consultations.

The Dieulafoy gastric malformation is a rare cause of upper gastrointestinal haemorrhage. When no obvious bleeding lesion is seen at laparotomy this diagnosis ought to be considered. Three such cases were identified and treated with simple underrunning of the lesion with no mortality and minimal morbidity. Follow-up endoscopy in each patient showed complete healing of the lesion.

Thirteen cases of primary appendicular adenocarcinoma are reported. This rare tumour usually presents as acute appendicitis. The correct diagnosis is rarely entertained before or during surgery. The main treatment choice lies between appendicectomy alone and appendicectomy followed by right hemicolectomy. There are anatomical reasons for advising the latter and survival figures from the literature tend to support this preference. The cases reported here indicate that in the period 1972-1984, in the North West Region, there was a slight preference for appendicectomy alone. The additional procedure of right hemicolectomy did not confer any clear-cut survival advantage.

Delay to diagnosis from first symptom has been assessed in 332 patients with colorectal cancer treated by the three general surgeons in Trafford Health Authority. Delay was divided into three parts; that due to (a) the patient, (b) the general practitioner and (c) the hospital. There was no significant difference in delay between Dukes stage B and C patients but there was a significant difference in survival at two years between these two stages. Delay for patients with risk factors as family histories or diverticular disease was not significantly different to patients without these factors. When compared to other series delay has been shortened, particularly general practitioner and hospital delay. Fewer patients presented as emergencies and a greater proportion of patients had disease at an earlier stage. However, these favourable aspects are not reflected in an improved survival at 2 years.

The effect of either prophylactic antibiotic or wound antiseptic on bile bacteriology, wound and other postoperative sepsis has been studied in a controlled prospective randomised trial of 243 patients undergoing biliary surgery at a district general hospital. Wound infection rates were significantly less in patients given intravenous ceftriaxone (1%) at induction of anaesthesia when compared to povidone iodine sprayed into the wound at the completion of surgery (9%) (P = 0.02). In all but one patient infected wounds grew organisms identical to those cultured from the bile. There were also fewer chest and urinary infections in the ceftriaxone group but this was not statistically significant.

Bile bacteriology, wound sepsis and the effect of prophylactic antibiotics have been studied in a controlled prospective double blind randomized trial on 375 patients undergoing elective cholecystectomy at a district general hospital. We have examined the overall prevalence of bacteria in bile and have identified several factors associated with an increased incidence. The identity of organisms isolated from a total of 21 patients with infected wound swabs was compared with isolates from the bile at operation, and in only two instances was there a correlation. Cephazolin, given either pre-operatively, or into the wound, reduced wound infection rates compared with a control group (from 11.8 to 2.4 per cent, P less than 0.005). We conclude that the majority of wound infections in this series were caused by organisms from the patients' skin or exogenous sources, rather than by bacteria from the biliary system.

Evidence for associations between organic disease and psychopathology is reviewed and it is concluded that some of this is determined by complaint and consultation behaviours. The concept of illness behaviour is described. The Self Care Assessment Schedule (SCAS) is a new measure of illness behaviour and has been used to provide an independent assessment of psychiatric day patients, gynaecology and surgical outpatients. Only weak positive correlations were found between SCAS scores and mental illness, measured using the General Health Questionnaire (GHQ). Subjects with organic pathology differed little from those without organic pathology, with regard to SCAS and GHQ scores. However SCAS and GHQ scores were more highly correlated in those without organic pathology. It is concluded that claimed associations between physical disease and psychopathology should be based on objective evidence rather than subjective complaints and that this should be found across the entire spectrum of illness behaviour.

Sixty-two patients with intermittent claudication associated with peripheral arterial diseases were treated with clofibrate, 2 g daily, for a minimum of six months. Progress was compared with that in a similar pretreatment period and also with that of a matched untreated control group of 27 patients. The most striking effect of clofibrate was a steep and sustained fall in whole-blood viscosity measured over a wide range of shear rates. This was associated with a significant fall in abnormally raised initial plasma-fibrinogen levels. An increased proportion of patients on treatment showed evidence of clinical improvement. Clofibrate had no effect on the susceptibility of red blood cells to autoxidation but it led to a significant shift in the red cell fatty acid pattern.

Increased blood viscosity has been shown to be an important factor in reducing blood flow in a review and analysis of the history, clinical findings, and haemodynamic, rheological, radiological, and biochemical measurements in 126 patients with intermittent claudication. In some patients increased viscosity seemed to be the determining cause of claudication. A raised plasma fibrinogen was the most common single biochemical abnormality. The results of conventional serum lipid and lipoprotein estimations were abnormal in the series as a whole but did not correlate with clinical findings or flow measurements at individual patient level. There was, however, a significant correlation between some clinical findings and the susceptibility of the red cells to autoxidation.

To assess the prognostic significance of clinical and laboratory findings in intermittent claudication a group of 62 untreated patients was followed up in detail for periods of from one to three years. There was a significant correlation between progressive deterioration of the peripheral circulatory disturbance and the initial blood viscosity, the plasma fibrinogen level, and the susceptibility of red cell lipids to autoxidation.
