Ductal Carcinoma In Situ with Microinvasion on Core Biopsy: Evaluating Tumor Upstaging Rate,Lymph Node Metastasis Rate,and Associated Predictive Variables

Annals of Surgical Oncology - The role of sentinel lymph node biopsy (SLNB) when ductal carcinoma in situ with microinvasion (DCISM) is identified on core biopsy is unclear. Our aim was to assess...     

Efficacy and safety of morning versus evening fluoxetine administration

A total of 120 patients who met DSM-III criteria for unipolar major depressive episode were equally randomized to fluoxetine a.m. or fluoxetine p.m. treatment groups, such that 30 patients were in each group at each of two sites. Patients received 20 to 80 mg of fluoxetine every day for 5 weeks; the dose was based on clinical response. Highly significant within-treatment improvement was reflected by changes in mean scores on the Hamilton Rating Scale for Depression (total score and factors), the Raskin Depression Scale, the Covi Anxiety Scale, the Clinical Global Impressions Scale for Severity, and the Clinical Global Impressions Scale for Improvement. No significant differences occurred between the a.m. and p.m. groups for any efficacy variable. Evaluation of adverse events and vital signs indicated no clinically significant differences between the two treatment groups. The data indicate that fluoxetine is equally efficacious and well tolerated regardless of the time of day it is administered and suggest that fluoxetine may be administered at either time of day without affecting clinical course.     

Source agreement in assessing youth stress and negative affectivity: New evidence for an old problem

The present study examined dichotomies potentially relevant to parentchild and interparent agreement in the assessment of internalizing problems in youngsters. Specifically, 98 children and their parents completed the Daily Life Stressors Scale or a variant to examine child ratings of daily stress, parent ratings of their children's daily stress, and parent predictions of how their children would self-rate their stress. In addition, a distinction was made between subscores of negative affectivity and stressful life events. Results indicated moderate parent-child and interparent agreement, with the latter somewhat more influenced by a negative affectivity-stressful events dichotomy. Parent-child agreement appeared more enhanced for items involving more parental contact. Implications of these data for future research are discussed.     

Management of postoperative mediastinitis in infants and children by muscle flap rotation

Between July 1, 1976, and June 30, 1986, at the Henrietta Egleston Hospital for Children, 2,242 infants and children underwent palliation or repair of a congenital heart defect. Twenty-one (0.94%) of these patients developed mediastinitis following a median sternotomy. Nineteen of these twenty-one patients had required cardiopulmonary bypass. All patients had positive mediastinal cultures. The first 8 patients were managed traditionally by debridement and irrigation. Three of these patients suffered serious metabolic complications related to the povidone-iodine irrigant, which resulted in 1 death. Another patient died from persistent sepsis following debridement. Subsequently, 13 patients were managed by early debridement and rotation of the pectoralis major or rectus abdominis muscle flaps, or both. Following muscle flap rotation and early wound closure, 2 patients had subsequent incisional complications. One patient had incisional dehiscence and 1 had a superficial skin separation. Two deaths in this group, 28 and 51 days, respectively, following muscle flap rotation, resulted from nonincisional problems in patients with healed median sternotomies. The group having muscle flap rotation required a significantly shorter duration of postoperative ventilatory support (3.2 versus 24 days, p less than 0.05) and a significantly shorter confinement in the intensive care unit (6.2 versus 33 days, p less than 0.01). Also, the physiological and physical trauma of continued wound care in the awake child was minimized in the group with muscle flap rotation.     

PS15PAEDIATRIC GUN SHOT INJURIES IN NEW ZEALAND: A DEMOGRAPHIC ANALYSIS OF AN AVOIDABLE CAUSE OF SIGNIFICANT CHILDHOOD MORBIDITY

Purpose New Zealand has a reputation for an outdoors lifestyle that includes hunting and tramping. New Zealanders own over a million guns and these are widely distributed throughout the rural and urban communities. Although its gun laws are not liberal, children still suffer gun shot injuries. The aim of this study was to examine the injuries children receive from firearms in New Zealand, their circumstances and long term morbidity. Methodology A retrospective review of all children admitted to the four New Zealand paediatric surgical hospitals (at Auckland, Hamilton, Wellington and Christchurch) with gun shot injuries over 10 yr period 1996–2005 was undertaken. Data were compared with published literature from elsewhere. Results Overall, the incidence of gunshot injuries in New Zealand is low compared with many other developed countries. The majority are caused by air rifles. Most are superficial but some may lead to long term morbidity. Conclusions Although New Zealand gun laws require air rifle owners to be over 18 yrs of age, children often are victims of air rifle misuse, particularly in urban areas. Mortality is rare, but some children suffer long term morbidity. Our data may enable preventative measures to be better focused.
