Intraoperative Hypothermia Is Associated with Reduced Acute Kidney Injury After Spine Surgery Under General Anesthesia: A Retrospective Observational Study
Authors: Oh Tak Kyu , Ryu Jung-Hee , Sohn Hye-Min , Jeon Young-Tae 
Published: October 2018

Background:
Although hypothermia is known to have protective effects against ischemic injuries, the effects of hypothermia on kidney injury have not yet been elucidated. Therefore, this study aimed to identify the association between intraoperative hypothermia and postoperative acute kidney injury (AKI) in patients who underwent spine surgery under general anesthesia.

Methods:
In this retrospective observational study, we analyzed the medical records of adult patients who underwent elective spine surgery between January 2010 and March 2018. Patients were classified into the normothermia group (36.5 to 37.5°C), mild hypothermia group (35 to 36.5°C), and hypothermia group (<35°C) based on the mean intraoperative temperature, measured using an esophageal stethoscope. The association between mean intraoperative temperature and the incidence of postoperative AKI was analyzed using logistic regression analysis after inverse probability of treatment weighting (IPTW) adjustment.

Results:
The analysis included 6520 patients, of whom 248 (3.8%) were diagnosed with AKI within POD 3. After applying IPTW adjustment, the incidence of postoperative AKI was 32% lower in the hypothermia group than in the normothermia group (odds ratio, 0.68; 95% confidence interval, 0.53-0.87; P=0.002), whereas the incidence of postoperative AKI in the mild hypothermia group was not significantly different from that in the normothermia (P=0.139) and hypothermia groups (P=0.075).

Conclusions:
This study showed that intraoperative hypothermia is associated with a reduction in the incidence of AKI following spine surgery under general anesthesia. Further, this association was evident in the group with hypothermia <35°C.

Authors: Colman Matthew W. , Baronne Lon M. , Brodke Darrel S. , Woodbury Ashley M. , Annis Prokopis , Lawrence Brandon D. 
Published: October 2018

Study Design:
This is a retrospective analysis.

Objective:
The purpose of this study was to compare the clinical, radiographic, and perioperative complication profiles of performing an interbody and posterior arthrodesis (CAGE) versus posterolateral lumbar fusion (PLF) alone in patients undergoing surgery for degenerative spondylolisthesis (DS).

Summary of Background Data:
DS is a common disorder that, failing nonoperative treatment, may be managed with surgical decompression and concomitant posterior arthrodesis. At present, the risk/benefit ratio of including an additional interbody arthrodesis has not been clearly delineated in the literature.

Materials and Methods:
We reviewed 174 consecutive patients (118 female and 56 male) diagnosed with single-level DS that met the inclusion/exclusion criteria, from January 1, 2000 to August 1, 2011. Clinical outcomes, fusion rates, radiographic outcomes, and complication profiles were recorded.

Results:
We identified 174 patients who received a single-level lumbar interbody fusion with posterolateral fusion (CAGE, n=89) or posterolateral fusion alone (PLF, n=85). No difference in patient-reported outcomes or fusion rate was detected between the 2 groups. We did identify better segmental lordosis increase (4.9±3.2 vs. 0.9±1.9 degrees; P=0.001) and interdiscal height change (2.1±2.4 vs. 0.6±1.6 mm) in the CAGE group. Operative time, 199.8±36.6 versus 142.6±28.5 minutes (P<0.001); blood loss, 355±216.4 versus 269±28.5 mL (P<0.001); and postoperative radiculitis, 28.9% versus 7.0% (P=0.003) were worse in the CAGE group compared with the PLF group.

Conclusions:
The ideal surgical approach when treating patients with DS remains in question. This study suggests, when comparing PLF with or without additional interbody fusion, that the lack of clinical or fusion-related benefit may not justify the higher risk profile including longer surgery, higher blood loss, and increased risk of postoperative radiculitis. Long-term prospective studies are required to further clarify these findings.

Published: October 2018

Background:
Ambulance data provide a useful source of population-based and spatiotemporally resolved information for assessing health impacts of air pollution in nonhospital settings. We used the clinical records of paramedics to quantify associations between particulate matter (PM2.5) and diabetic, cardiovascular, and respiratory conditions commonly managed by those responding to calls for emergency ambulance services.

Methods:
We evaluated 394,217 paramedic assessments from three states in Southeastern Australia (population 13.2 million) and daily PM2.5 concentrations modeled at 5 km resolution from 2009 to 2014. We used a time-stratified, case-crossover analysis adjusted for daily meteorology to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) for each clinical outcome per 10 µg/m3 increase in daily PM2.5 at lags from 0 to 2 days.

Results:
Increased PM2.5 was associated with increased odds of paramedic assessments of hypoglycemia (OR = 1.07; 95% CI = 1.02, 1.12, lag 0), arrhythmia (OR = 1.05; 95% CI = 1.02, 1.09, lag 0), heart failure (OR = 1.07; 95% CI = 1.02, 1.12, lag 1), faint (OR = 1.09; 95% CI = 1.04–1.13, lag 0), asthma (OR = 1.06; 95% CI = 1.01, 1.11, lag 1), chronic obstructive pulmonary disease (OR = 1.07; 95% CI = 1.01, 1.13, lag 1), and croup (OR = 1.09; 95% CI = 1.02, 1.17). We did not identify associations with cerebrovascular outcomes.

Conclusions:
Ambulance data enable the evaluation of important clinical syndromes that are often initially managed in nonhospital settings. Daily PM2.5 was associated with hypoglycemia, faint, and croup in addition to the respiratory and cardiovascular outcomes that are better established.
Management of the Lateral Breast
Authors: Khincha Priyatma P. , Pikturnaite Jurga , Mahajan Ajay L. 
Published: October 2018

Summary:
Breast asymmetry is a common finding in developing adolescents. In select cases, there is maldevelopment of 1 or both breasts, which persists into adulthood and causes significant negative impact on life. Various surgical techniques (eg, breast augmentation/reduction) and nonsurgical techniques (eg, bras/gel inserts) are currently in practice to achieve breast symmetry. We describe a unique case of a young lady with Poland’s syndrome, who presented with a lateralized right breast. We have used a V-Y advancement flap, along with a breast implant, to medialize the breast and achieve symmetry in contour and volume, followed by medialization of the nipple areolar complex. Using this technique produced an excellent result on our patient. We, therefore, feel that using the V-Y advancement flap is a novel and good option for dealing with difficult cases of lateralized breast.
New Approach to Oncoplastic Breast Conservation: Combining Autologous Volume Replacement and the Wise-pattern Mammaplasty
Authors: Schwartz Jean-Claude D. 
Published: October 2018

Background:
Oncoplastic breast-conserving surgery describes a set of techniques that allow for generous oncological resection with immediate tumor-specific reconstruction. These techniques are classically divided into either volume displacement (local breast flaps and or reduction mammaplasty/mastopexy strategies) versus volume replacement strategies (transfer of autologous nonbreast tissue from a local or distant site and, less commonly, implant placement). There have been few descriptions of merging these 2 classical approaches to facilitate breast-conserving surgery. The purpose of this report was to evaluate the efficacy of combining the most common oncoplastic volume displacement strategy (Wise pattern mammaplasty) with simultaneous autologous volume replacement from the lateral intercostal artery perforator (LICAP) flap to reconstruct the extensive partial mastectomy defect in patients with ptosis.

Methods:
A retrospective analysis of 25 consecutive patients with multifocal or multicentric breast cancers who underwent simultaneous volume replacement from the LICAP flap and volume displacement (Wise pattern mammaplasty) to achieve breast conservation was performed between January 2016 and January 2018. Clinical outcomes and postoperative complications were examined.

Results:
Twenty-five consecutive patients with a mean age of 56 years (range, 37–74 years) and mean body mass index of 28 kg/m2 (range, 22–37 kg/m2) all successfully underwent breast conservation by simultaneously employing the LICAP flap and Wise pattern mammaplasty to reconstruct the partial mastectomy defect. The average resection specimen weight was 220 g (range, 130–310 g) and average size of the malignancy resected was 6.5 cm (range, 3.7–9.2 cm). Three patients (12%) required re-excision for close or positive margins but were ultimately cleared. There were no complications related to the donor site. There were 4 patients (16%) with delayed wound healing related to the Wise pattern closure but no instances of LICAP necrosis or failure.

Conclusions:
The merger of Wise pattern volume displacement and autologous volume replacement techniques represents a novel strategy that is useful in the most challenging breast conservation patients with some degree of ptosis.

Published: October 2018

Purpose:
To evaluate clinical features and survival outcomes of uveal metastasis based on patient age.

Methods:
Retrospective analysis of all patients with uveal metastasis evaluated on the Ocular Oncology Service, Wills Eye Hospital, Philadelphia, PA, USA between February 1, 1974 and June 1, 2017. The features and outcomes were analyzed based on patient age classified as children (0–20 years), young adults (21–40 years), middle [aged] adults (41–60 years), older adults (61–80 years) and senior adults (81–100 years).

Results:
There were 1111 consecutive patients, including children (n = 3, <1%), young adults (n = 77, 7%), middle adults (n = 472, 42%), older adults (n = 509, 46%), and senior adults (n = 50, 4%). At uveal metastasis diagnosis, demographics included mean patient age of 60 years, Caucasian race (88%), and female gender (64%). Compared to the largest cohort (older adults), there were significant differences (age group versus [vs.] older adults) in Caucasian race (senior adult 98% vs. 89%, p = 0.042), male sex (young adults: 22% vs. 43%, p < 0.001) (middle adults: 29% vs. 43%, p < 0.001), unilateral tumor (young adult: 70% vs. 86%, p < 0.001) (middle adult: 79% vs. 86%, p = 0.003) (senior adults: 96% vs. 86%, p = 0.045), and cancer origin in breast (young adults: 51% vs. 32%, p = 0.002) (middle adults: 44% vs 32%, p < 0.001), lung (young adults: 14% vs. 30%, p = 0.004), kidney (young adults: 0% vs. 5%, p = 0.043), prostate (middle adults: 1% vs. 4%, p = 0.001), gastrointestinal tract (senior adults: 8% vs. 2%, p = 0.028), and others (children: 100% vs. 4%, p < 0.001) (young adults: 10% vs. 4%, p = 0.044). Kaplan-Meier survival (children, young, middle, older, and senior adults) at 1 year was 33%, 48%, 60%, 62%, and 76% and at 5 years was 0%, 22%, 29%, 25%, and 40%, respectively, with no difference per age category. The mean overall survival was 17.2 months and children demonstrated hazard ratio (HR) for death at 1 year of 2.1 relative to older adults.

Conclusion:
Uveal metastasis is found in all age groups. Compared to older adults, primary cancer site was more often breast and less likely lung in young and middle adults. Other rare sites were more often seen in children. Survival outcomes at 1 and 5 years were most favorable for senior adults and least favorable for children.

Authors: McGinnis Emily , Ayyagari Rajeev , Tan Ruo-Ding , Tuttle Edward , Cammarata Sue , Tillotson Glenn 
Published: October 2018

Purpose
Common causes of hospitalizations in the United States are acute bacterial skin and skin-structure infections (ABSSSIs). The objectives of this retrospective study were to characterize hospitalized ABSSSI patients including comorbidities and identify the microorganisms associated with the infection.

Methods
Adults (>18 years) hospitalized with 1 or more primary ABSSSI diagnosis were selected from the Cerner Health Facts electronic medical records database between 2009 and 2013. Causative microorganisms for ABSSSI and Gram-stain type were identified from microbiology culture, including patients with methicillin-resistant Staphylococcus aureus (MRSA).

Results
Of the 11,705 patients identified, 51.8% were male, with a mean age of 55 years at admission; 49.7% were obese; and 30.9% had diabetes. More than half (56.6%) of patients had no microbiology culture results. Of the patients with an identified ABSSSI-causing pathogen, 63.9% were gram-positive, including 18.4% infected with MRSA; 11.9% were gram-negative; and 24.2% had mixed infections (gram-positive and gram-negative), including 3.6% with MRSA. After adjusting for confounding variables, a significant association was noted between obesity and 30-day ABSSSI-related readmission among males, patients younger than 65 years, and patients without MRSA.

Implications
Hospitalized ABSSI patients had comorbidities, including obesity, diabetes, hypertension, and depression, which can complicate antibiotic selection. Patient characteristics and pathogen coverage must be considered in antibiotic selection in ABSSSI.

Authors: Schmidt-Kraepelin Christian , Engelke Christina , Kahl Kai G. , Cordes Joachim 
Published: October 2018

Abstract

Background
Treatment of schizophrenia with depot medication has advantages compared with oral medication, and among these include an improved compliance. Despite such advantages, prescription rates in many European countries are lower than 20%. The aim of this survey was to study the attitudes toward depot medication among the German general population. To the best of our knowledge, only selective samples have been investigated up until now.

Methods
A representative sample of 754 people were interviewed via telephone by a professional market research and polling organization. The questionnaire queried demographic characteristics, experience with medication, and the treatment of mental disorders. Subjects' attitudes toward medication in general, long-term medication, and depot medication were surveyed.

Results
Most (66.7%) of the subjects stated that they would be willing to receive depot medication. Subjects who experienced the treatment of mental disorders were more likely to be willing to receive depot medication. Among the reasons for not using depot medication, “fear of injection” (66.3%) and “more self-control when taking medication as tablets” (48.9%) were stated as the most frequent reasons.

Conclusions
This study found a good acceptance of antipsychotic depot medication among the German general population in terms of willingness to receive such treatment. We argue that the clinical practitioners' assumptions that depot formulations would be refused by many patients are unsubstantiated.

Authors: Martin-Sanz Eduardo , Diaz Joaquin Yanes , Esteban-Sanchez Jonathan , Sanz-Fernández Ricardo , Perez-Fernandez Nicolas 
Published: October 2018

Objective:
This study aimed to evaluate the changes in the VOR gain after intratympanic gentamicin therapy and to correlate them with the mid-term effects on the control of vertigo, in a population of Menière's disease patients.

Study Design:
The study design was a prospective “Outcomes research.”

Setting:
Tertiary referral center.

Patients:
This study included 20 patients with unilateral Menière's disease refractory to medical therapy for at least 1 year, and treated with an on demand intratympanic gentamicin protocol.

Intervention:
Therapeutic.
Main Outcome Measure: Audiometry, caloric testing, and a vHIT before beginning the protocol were performed. Patients underwent weekly vHIT assessments until a significant gain reduction was observed. Subsequently we performed vHIT tests 1 month after the therapy completion, and then every 3 months for at least 1 year.

Results:
Complete vertigo control (class A) was achieved in 14 patients at the 12-month follow-up assessment. We observed a significant reduction in VOR gain values at the 3-week follow-up assessment. We found a significant correlation between the 1-month posttreatment ipsilateral hVOR gain and the rate of vertigo recurrence after the first IT gentamicin treatment (p = 0.012; r2 = 0.400). At the mid-term assessment, 10 patients exhibited a significant partial recovery of the hVOR gain.

Conclusions:
The delayed effect of intratympanic gentamicin and the subsequent gain restoration are factors that may influence the patients’ outcome. The feasibility of the vHIT system makes it a useful tool to monitorize the VOR changes.

Authors: Höing Benedikt , Kirchhoff Lisa , Arnolds Judith , Hussain Timon , Buer Jan , Lang Stephan , Arweiler-Harbeck Diana , Steinmann Joerg 
Published: October 2018

Hypothesis:
Biofilm formation on cochlear implant (CI) surfaces differs between bacterial species and can be reduced by the application of S53P4 bioactive glass.

Background:
The formation of bacterial biofilms on medical devices, such as cochlear implants, can lead to chronic infections resulting in the need for implant removal. In this study, various surfaces of three CI implant kits from different manufacturers were examined for bacterial biofilm formation and reduction of a pre-existing biofilm by the application of bioactive glass.

Methods:
Biofilm formations of 4 bacterial species causing implant-related infections were tested on 17 different surfaces: Pseudomonas aeruginosa (ATCC9027), Staphylococcus aureus (ATCC6538), Staphylococcus epidermidis (ATCC12228), and Streptococcus pyogenes (ATCC19615). For P. aeruginosa and S. aureus biofilm reduction after application of S53P4 bioactive glass was evaluated.

Results:
All tested microbial species formed biofilms on the examined CI surfaces in a strain-dependent manner. For S. aureus, a significantly higher biofilm formation on metal components compared with silicone was found whereas the other strains did not show a material specific biofilm formation. Application of S53P4 bioactive glass resulted in a significant reduction of P. aeruginosa and S. aureus mature biofilm.

Conclusion:
The four bacteria species displayed biofilm formation on the CI surfaces in a species- and material-specific manner. The results show that bioactive glass can reduce biofilm formation on CI materials in vitro. Future studies are necessary to confirm the results in vivo.
Microwave ablation combined with transcatheter arterial chemoembolization is effective for treating unresectable hepatoblastoma in infants and children

Published: October 2018

Abstract
The present study is to evaluate the feasibility and efficacy of microwave ablation (MWA) combined with transcatheter arterial chemoembolization (TACE) in the treatment for unresectable hepatoblastoma in infants and children. A total of 17 patients with PRETEXT stage III and IV hepatoblastoma that was unresectable by conventional resection were included in the present study. The patients were treated with TACE, MWA, and chemotherapy. All cases were diagnosed by computed tomography (CT) and liver tumor biopsy before TACE procedure. All patients received 2 courses of TACE and 1 to 2 times of MWA. Finally, several cycles of chemotherapy were arranged. Among the 17 patients, 14 were alive and had normal alpha-fetoprotein (AFP) levels. The other 3 patients died from tumor progression. The follow-up periods ranged from 10 to 68 months. Complete ablation was achieved in the 14 patients (14/17, 82.35%). Most patients were well tolerated during the whole course except for 1 patient with pneumonedema after TACE and another 1 with biloma after MWA. No marked chemotherapeutic agent-induced toxicity occurred. After chemotherapy or TACE, transient blood indicators and symptoms were observed as follows: myelosuppression, abnormal liver function, gross hematuria, fever, and abdominal pain. Transient symptoms after MWA were fever, abdominal pain, and massive gross hematuria. The present study demonstrates that MWA combined with TACE is a safe and effective method for treating unresectable hepatoblastoma in infants and children with controllable side effects.
Rituximab for idiopathic and IgG4-related retroperitoneal fibrosis
Authors: Wallwork Rachel , Wallace Zachary , Perugino Cory , Sharma Amita , Stone John H. 
Published: October 2018

Abstract
Retroperitoneal fibrosis (RPF) refers to a fibro-inflammatory lesion in the retroperitoneum, often anterolateral to the aorta. Most cases are due to IgG4-related disease (IgG4-RD) or are idiopathic. RPF can lead to severe morbidity. Treatment strategies remain poorly-defined. We evaluated the efficacy and safety of rituximab (RTX) for idiopathic or IgG4-related RPF.
We retrospectively reviewed the records of patients who had RPF treated with RTX. Treatment response was determined by assessing changes in both clinical features, including symptoms and laboratory measurements, as well as in the radiographic dimensions of the lesion.
Twenty-six patients with IgG4-related (n = 19) or idiopathic RPF (n = 7) were identified. Patients without histopathological evidence of IgG4-RD on either retroperitoneal biopsies or sampling of extra-retroperitoneal organs were considered to have idiopathic RPF. Of the 26 patients, 19 (73%) received RTX without additional glucocorticoids. All 19 patients who presented with pain reported symptomatic improvement following RTX. Among 25 patients with follow-up imaging, 22 (88%) had radiologic improvement. Among 10 patients with ureteral stents and/or percutaneous nephrostomy tubes, 4 (40%) underwent successful stent or tube removal. Responses to treatment were similar among those treated with RTX monotherapy and those treated with RTX and glucocorticoids. RTX was generally well tolerated, but 3 (12%) patients experienced severe infections.
In this study, RTX for RPF led to resolution of symptoms in all patients and radiographic improvement in the majority. Prospective studies of RTX for RPF are indicated.
