Analyzing treatment aggressiveness and identifying high‐risk patients in diabetic foot ulcer return to care

Rates of diabetes and its associated comorbidities have been increasing in the United States, with diabetic foot ulcer treatment representing a large cost to the patient and healthcare system. These ulcers often result in multiple hospital admissions. This study examined readmissions following inpatient care for a diabetic foot ulcer and identified modifiable factors associated with all‐cause 30‐day readmissions to the inpatient or emergency department (ED) setting. We hypothesized that patients undergoing aggressive treatment would have lower 30‐day readmission rates. We identified patient discharge records containing International Classification of Disease ninth revision codes for both diabetes mellitus and distal foot ulcer in the State Inpatient and Emergency Department databases from the Agency for Healthcare Research and Quality, Healthcare Cost and Utilization Project in Florida and New York, 2011–2012. All‐cause 30‐day return to care visits (ED or inpatient) were analyzed. Patient demographics and treatment characteristics were evaluated using univariate and multivariable regression models. The cohort included 25,911 discharges, having a mean age of 63 and an average of 3.8 comorbidities. The overall rate of return to care was 30%, and 21% of subjects underwent a toe or midfoot amputation during their index stay. The most common diagnosis codes upon readmission were diabetes mellitus (19%) and infection (13%). Patients with a toe or midfoot amputation procedure were less likely to be readmitted within 30 days (odds ratio: 0.78; 95% confidence interval: 0.73, 0.84). Presence of comorbidities, black and Hispanic ethnicities, and Medicare and Medicaid payer status were also associated with higher odds of readmission following initial hospitalization (p < 0.05). The study suggests that there are many factors that affect readmission rates for diabetic foot ulcer patients. Understanding patients at high‐risk for readmission can improve counseling and treatment strategies for this fragile patient population.     

Mini-open thoracoscopically assisted thoracotomy versus video-assisted thoracoscopic surgery for anterior release in thoracic scoliosis and kyphosis: a comparison of operative and radiographic results

BACKGROUND CONTEXT: Combining anterior release and interbody fusion with posterior instrumented fusion is an accepted treatment for severe rigid spinal deformity. Video-assisted thoracoscopic surgery (VATS) and mini-open thoracoscopically assisted thoracotomy (MOTA) are two minimally invasive approaches to the thoracic spine. Both reduce surgical trauma, improve cosmesis and provide effective exposure for release and fusion. Published data and the authors' surgical experience have demonstrated that both techniques are equivalent in degree of release to traditional open thoracotomy, but no comparison between these two minimally invasive alternatives has been published to our knowledge. PURPOSE: This study compared MOTA and VATS under the hypothesis that both result in similar corrections and comparable operative parameters when used in conjunction with posterior instrumented fusion. STUDY DESIGN/SETTING: Retrospective chart review of consecutive case series by two surgeons. PATIENT SAMPLE: Twenty-one (13 female, 8 male) patients underwent MOTA and 24 patients (17 female, 7 male) underwent VATS for anterior release, discectomy and fusion prior to posterior instrumented fusion. OUTCOME MEASURES: Outcomes were measured at a minimum of 1-year follow-up and included radiographic Cobb measurements and operative parameters. METHODS: The indications for surgery included rigid and severe scoliosis or thoracic kyphosis. Data collection included preoperative demographics, number of levels released, primary curve correction, operative time and blood loss. Data were normalized per number of levels released anteriorly. Statistical analysis of results was done using a two-sample t test assuming equal variances with two-tail p values less than .05. RESULTS: More anterior levels were operated on average in the VATS group (6.33 vs. 4.38 levels). Curve correction per anterior level released was similar in both groups (8.7 and 8.8 degrees/level for MOTA and VATS, respectively). There was a significant difference in operative time with MOTA averaging 131.7 minutes and VATS averaging 162.8 minutes. However, a comparison of the operative time per anterior level operated, approached statistical significance in favor of VATS (33.0 vs. 28.4 minutes, p=.08). There was no significant difference in estimated blood loss during the anterior portion of the surgeries. There was a trend toward decreased blood loss per operated level favoring VATS (68.4 vs. 38.9 cc, p=.09). CONCLUSIONS: Both approaches resulted in corrections that compare favorably with open thoracotomy. We suggest that a factor in choosing between these two minimally invasive techniques is the number of thoracic levels requiring release. For four levels or less, MOTA provides an excellent alternative to standard thoracotomy. For five or more levels, VATS provides for excellent exposure of additional levels with the advantages of less operative time and blood loss per operated level.     

Five Percent Lidocaine Cream Applied Simultaneously to the Skin and Mucosa of the Lips Creates Excellent Anesthesia for Filler Injections

Background. Injection of filler substances into the lips is painful, and many patients also find the injection of local or regional anesthesia into the lips painful.
Objective. To develop a highly effective and painless form of anesthesia to facilitate injection of filler substances into the lips.
Methods. Five percent lidocaine cream was applied simultaneously to the skin, vermilion, and mucosa of the lips (with the use of a barrier to keep the cream in contact with the mucosa and out of the rest of the mouth) for 20 to 30 minutes.
Results. Profound anesthesia of the lips was reliably produced, with no complications.
Conclusions. This "anesthetic cream block" is easier to perform and better tolerated than injectable anesthetics. Use of this technique is likely to expand the range of physicians who perform filler injections on the lips and will probably also expand the range of patients who wish to have filler injections done on their lips and who (because they had little or no discomfort) are willing to return for additional filler injections in the future.     

The Role of Smoking in Breast Cancer Development: An Analysis of a Mayo Clinic Cohort

Abstract:  The purpose of this study was to assess the predictive value of smoking history on breast cancer diagnosis in a referral clinic population. We conducted a case–control study using clinical data collected on 8,097 female patients (1,225 breast cancer cases and 6,872 controls) seen in the Mayo Clinic Breast Clinic between August 1, 1993 and November 31, 2003. Breast cancer patients and noncancer patients significantly differed with respect to age at time of the index visit (p < 0.001), number of pregnancies (p = 0.006), number of live births (p = 0.002), vital status at last known follow-up (p < 0.001), current menstruation (p < 0.001), age at menopause (p < 0.001), history of hysterectomy (p < 0.001), use of oral contraception (p = 0.05), duration of oral contraception use (p = 0.001), use of other exogenous hormones (p < 0.001), duration of exogenous hormone use (p = 0.05), breast pain at time of index visit (p = 0.002), smoking status (p < 0.001), and use of five or more alcoholic beverages per week (p = 0.002). After adjustment for these baseline characteristics, having a personal history of smoking was found to be predictive of breast cancer diagnosis (odds ratios [OR] = 1.25, p = 0.004). Other positive predictors for breast cancer diagnosis were: age (OR = 1.02, p < 0.001), history of hysterectomy (OR = 0.66, p < 0.001), prior use of oral contraception for more than 11 years (OR = 2.10, p < 0.001), and prior use of other exogenous hormones/estrogen (OR = 1.81, p < 0.001). In this referral practice having a personal history of smoking is predictive of breast cancer diagnosis. Further studies are needed to further explore this relationship.     

Health-related quality of life in hospital inpatients with pressure ulceration: Assessment using generic health-related quality of life measures

The objective of this study was to determine the impact of pressure ulceration on health-related quality of life (HRQoL) and to undertake a pilot study for a future larger study. The study comprised two parts. First, data from a large UK prospective cohort study were analyzed and the HRQoL of 218 people with pressure ulcers was compared with that of 2,289 people without ulcers using the Short Form-36 (SF-36) questionnaire. After adjusting for age, sex, and comorbidities, patients with pressure ulceration had significantly lower scores for both the physical (coefficient=−3.12, p <0.001) and mental (coefficient=−1.50, p =0.04) component summary scores of the SF-36. Second, a small pilot study was conducted to explore use of other tools. HRQoL was assessed in six patients with and 16 patients without pressure ulcers using the SF-36, the EQ-5D and a pain visual analog scale. SF-36 scores indicated that patients with pressure ulcers had significantly poorer physical functioning ( d =22.3, p =0.001), role limitations due to physical problems ( d =12.9, p =0.02), and vitality ( d =20.6, p =0.04) than those without. EQ-5D scores were also poorer for patients with pressure ulceration, for both the visual analog scale ( d =19.2, p =0.02) and the index ( d =0.29, p =0.08). Patients with pressure ulceration had more perceived pain than those without; however, this difference was of borderline significance ( d =−23.9, p =0.06). Pressure ulceration therefore has an impact on HRQoL that is measurable and persists after adjusting for potential confounding.     

Quality of recovery from two types of general anesthesia for ambulatory dental surgery in children: a double-blind, randomized trial

Background:  Pediatric dental procedures are increasingly performed under general anesthesia because of the inability to cooperate, situational anxiety, or other behavioral problems. Volatile anesthetics have been associated with emergence delirium in children, whereas the use of propofol for anesthetic maintenance has been shown to reduce the incidence of emergence delirium after other types of surgeries. The aim of this study is to compare a sevoflurane-based anesthetic with a propofol-based technique as it relates to the incidence of emergence delirium and the quality of recovery after pediatric dental surgery, in patients who present with risk factors for perioperative behavioral issues.
Methods:  We prospectively collected data of 179 pediatric patients scheduled for ambulatory dental surgery using a double-blind and randomized trial design. Subjects were anesthetized following standardized protocols for either a sevoflurane- or a propofol-based technique. The incidence of emergency delirium, as measured by the Pediatric Anesthesia Emergence Delirium score, was the primary outcome. Secondary outcomes included the incidence of postoperative nausea and vomiting (PONV), number of nursing interventions in the recovery room, time to discharge readiness, and parental satisfaction.
Results:  We found no difference in the incidence of emergence delirium after both types of anesthesia. However, use of sevoflurane significantly increased both the risk of PONV and the number of postoperative nursing interventions. Discharge criteria were met about 10 min earlier in patients anesthetized with sevoflurane. Parental satisfaction was equally high with both anesthesia regimens.
Conclusions:  A propofol-based anesthetic technique did not lead to a lower incidence of emergence delirium after dental surgery in children but did result in significantly less PONV and fewer postoperative nursing interventions.     

Towards the twenty‐first century

It is suggested that the change in thought and technology in France, North America and England in the late 18th century is paralleled in the change in contemporary modes of behaviour and ways of looking at the self. The philosophy articulated at that time was by the philosophers of the Enlightenment and poets of Romanticism. Contemporary psychologies are concerned with the structure of the individual psyche and with social organization.

In this nuclear age we are threatened by nuclear war, over‐population and ecological imbalance, with irreversible destruction of living and technological resources. The contemporary philosophical and technological changes are on a global basis, as is the current conflict reflecting a war of man against himself. This can lead to either complete annihilation of humanity or to a re‐appraisal through a holistic approach to ourselves and our planet, based on internationalism.
