Methimazole in the Treatment of Melasma: A Clinical and Dermascopic Study

BACKGROUND: Melasma is a chronic hypermelanotic disorder that is challenging to treat; no single effective therapeutic agent for it has been discovered. Methimazole, an oral antithyroid drug, has a skin depigmenting effect when used topically. OBJECTIVE: We sought to evaluate the efficacy and safety of methimazole, applied during microneedling sessions and additional topical use in between sessions, for the treatment of melasma. METHODS: This split-face study included 30 Egyptian patients with melasma, each of whom received 12 microneedling sessions once per week for 12 weeks followed by topical methimazole on the right side of face and placebo on the left side. In between the sessions, topical methimazole 5% cream was applied twice per day on the right side and placebo on the left side. Assessments were performed using the Hemi-melasma Area and Severity Index (hemi-MASI) percentage of improvement, patient satisfaction, dermoscopy, and thyroid-stimulating hormone (TSH) serum levels. RESULTS: There were significant clinical and dermoscopic improvements; hemi-MASI scores on the methimazole-treated right sides were decreased (p<0.001). The percent of hemi-MASI score improvement was significantly associated with the malar pattern (p=0.031) and epidermal type (p=0.04) of melasma. About 70 percent of our studied patients reported being satisfied with their treatment response (7% excellent, 33% good, 30% fair). No significant local or systemic side effects were observed. Pre- and posttreatment serum TSH levels were within the normal range in all treated cases. CONCLUSIONS: Methimazole has the potential to be a safe and promising therapeutic agent for the treatment of melasma via dermapen-delivered microneedling sessions with topical use in between sessions.     

Fractional Photothermolysis: Treatment of Facial and Nonfacial Cutaneous Photodamage with a 1,550-nm Erbium-Doped Fiber Laser

PURPOSE: To evaluate the safety and effectiveness of a novel nonablative 1,550 nm erbium-doped fiber laser in the treatment of facial and non-facial photodamaged skin. METHODS: 50 patients with mild to moderate cutaneous photodamage, rhytides, and dyspigmentation received 3 successive treatments at 3-4 week intervals with a 1,550 nm erbium-doped fiber laser (Fraxel, Reliant Technologies Inc., San Diego, CA). Clinical improvement of treatment areas was independently determined by two masked assessors' evaluations of comparative photographs at baseline and 3, 6, and 9 months post-treatment using a quartile grading scale. Patient satisfaction surveys were also obtained at each follow-up visit. RESULTS: Mean clinical improvement at 3 months for the face was 2.23 and 1.85 for non-facial skin (p<0.001). Mean improvement at 6 months was 2.10 for the face and 1.81 for non-facial skin (p<0.001). Mean improvement at 9 months was 1.96 for the face and 1.70 for non-facial skin (p<0.001). At least 51% to 75% improvement in photodamage at the 9-month follow-up was achieved in 73 and 55% of facial and non-facial treated skin, respectively. Side effects were limited to transient erythema and edema in the majority of patients. No prolonged pigmentary changes or scarring were observed. Patient satisfaction surveys mirrored the observed clinical effects. CONCLUSION: The nonablative 1,550 nm erbium-doped fiber laser is an effective treatment for facial and non-facial photodamage, rhytides, and dyspigmentation with a favorable recovery and side effect profile.     

Hydroxocobalamin: An Effective Treatment for Flushing and Persistent Erythema in Rosacea

BackgroundExpression of inducible nitric oxide synthase (NOS) is higher in rosacea skin samples than in normal skin controls. Hydroxocobalamin is a potent inhibitor of all isoforms of NOS, capable of reducing the vasodilatations induced by nitric oxide.ObjectiveWe aimed to evaluate the role of hydroxocobalamin in treating facial flushing and persistent erythema of rosacea.MethodsThirteen patients with rosacea who displayed facial flushing and persistent erythema received 1 to 4 weekly intramuscular injections of hydroxocobalamin 1 to 2 mg. The outcomes were measured using the Clinician’s Erythema Assessment (CEA) by photography and an infrared thermometer to evaluate the difference in skin surface temperature (SST) of the cheeks before and after treatment.ResultsThirty minutes after the first dose of intramuscular injection of hydroxocobalamin, the mean CEA significantly reduced from 2.2± 0.6 to 1.2±0.4 (p<0.001), and average SST also significantly reduced from 36.7±0.70°C to 36.2±0.61°C (p<0.001) on the cheeks.ConclusionIn our patient sample, intramuscular administration of hydroxocobalamin was effective for immediate reduction of facial erythema associated with rosacea.     

Radiological and Clinical Factors Predicting the Facial Nerve Outcome following Retrosigmoid Approach for Large Vestibular Schwannomas (VSs)

Objective The aim of our study was to identify the radiological and clinical factors that predict postoperative facial nerve outcome following retrosigmoid approach for large vestibular schwannomas (VSs).Methods A total of 72 patients with large (≥ 3 cm) vestibular schwannomas was included in this retrospective study. Various parameters evaluated were age, gender, clinical presentation, tumor diameter in three planes, intrameatal extension, and pattern of growth.Results Age of the patient and presenting symptoms such as headache, ataxia, or preoperative facial nerve dysfunction correlated with poorer facial nerve outcome (p < 0.05). Patients with larger tumor volumes and extrameatal growth experienced a worse outcome (p < 0.05). Anterior and caudal extension (p = 0.001) correlated with poorer outcome, as well. Intrameatal extension and bony changes of the internal acoustic meatus did not correlate with the outcome (p > 0.05). Of the various examined factors, preoperative facial nerve function independently predicted postoperative facial nerve outcome.Conclusion Our study suggests that young patients with small tumor volume and normal facial nerve function at presentation are more likely to experience a good postoperative facial nerve outcome. These clinical and radiological parameters can be used to predict facial nerve outcome prior to surgery.     

Importance of Initial Peak Torque of the Supraspinatus Muscle during Shoulder Flexion

BackgroundMost previous studies have evaluated flexion strength to assess recovery after arthroscopic rotator cuff (RC) repair. However, limited data are available regarding peak torque at the initial angle (iPT) because most studies have measured flexion strength for peak torque (PT), particularly in small- and medium-sized supraspinatus tears. The purpose of this study was to compare conventional PT and iPT to evaluate supraspinatus muscle strength after arthroscopic RC repair in patients with small- and medium-sized supraspinatus tears.MethodsIsokinetic muscle performance testing was performed in 42 patients with small tears and in 47 patients with medium-sized tears. PT and iPT were evaluated before and 1 year after surgery and were recorded at an angular velocity of 60°/sec and 180°/sec with an isokinetic test.ResultsPT and iPT were significantly lower in the involved-side shoulders than in the uninvolved-side shoulders (PT: small tear, p < 0.001; medium tear, p < 0.001; iPT: small tear, p < 0.001; medium tear, p < 0.001) in both groups, preoperatively. However, postoperatively, in the involved-side shoulders, PTs were not different in both small- and medium-sized tears (all p > 0.05), but iPTs were significantly lower in the involved-side shoulders (small tear, p < 0.001; medium tear, p < 0.001). iPT was significantly lower in the involved side shoulders in the medium-sized tear group than in the small-sized tear group before and after surgery (p < 0.05). In the small- and medium-sized tear groups, tear size was significantly correlated with preoperative iPT in the involved-side shoulders (small tear: r = −0.304, p = 0.046; medium tear: r = −0.323, p = 0.027). However, pain visual analog scale was significantly correlated with preoperative (small tear: r = −0.455, p = 0.002; medium tear: r = −0.286, p = 0.044) and postoperative (small tear: r = −0.430, p = 0.005; medium tear: r = −0.354, p = 0.021) iPT in the involved-side shoulders. Furthermore, fatty infiltration grade of the supraspinatus muscle and global fatty degeneration index were not associated with preoperative and postoperative PT and iPT in each group (all p > 0.05).ConclusionsiPT is as important as conventional PT in isokinetic testing to assess supraspinatus muscle strength before and after RC repair.     

Safety and Efficacy of Restoring Facial Symmetry Using Polydioxanone Thread Face Lift Technique in Patients with Facial Palsy

BackgroundFacial nerve palsy often leads to functional and physiological impairment in patients and they often suffer from social stigma. The use of polydiaxone (PDO) threads has long been used to treat facial furrows and age-related sagging in the face. The basic principle of the thread lift procedure is placing cogged threads in the subcutaneous plane along a planned trajectory. The efficacy and ease of this procedure compared to a traditional face lift has made PDO threads a popular option in the past three decades. MethodsWe treated 50 patients with a drooping face on one side following facial paralysis with thread lifting and botulinum injections to control contralateral hypertrophy and ipsilateral synkinesis. The Facial Grading System or the serial Sunnybrook Facial Grading System (SB scores) was used to assess at all the visits and serial photographs were recorded.ResultsFollowing the threading procedure, all 50 patients displayed improved facial symmetry. There was significant improvement in the baseline SB scores compared to the scores over following year, with all the scores having significant p value less than 0.05.Conclusion Based on our results, subdermal suspension with re-absorbable threads in conjunction with botulinum toxin constitutes an efficient and safe procedure for face lifting and rejuvenation of a drooping face as a result of long-lasting facial paralysis.     

Successful Topical Application of Botulinum Toxin After Microneedling Versus Microneedling Alone for the Treatment of Atrophic Post Acne Scars: A Prospective,Split-face,Controlled Study

BackgroundAcne scars are a source of cosmetic concern for most of the patients.ObjectiveWe sought to compare the clinical efficacy and safety of topical botulinum toxin A (BTX-A) application immediately after microneedling (Mn) versus Mn with saline in the treatment of atrophic acne scars.MethodsForty patients with atrophic acne scars (rolling, boxcar, and mixed types) were enrolled in a split-face study; microneedling was performed on both sides of the face followed by an application of topically diluted botulinum toxin on one side (Side A) and saline on the other (Side B) for two sessions both two weeks apart. Evaluation was done at baseline, two and four weeks after the session. Follow-up was performed after six months. The assessments included blinded clinical assessment and patient’s satisfaction.ResultsAfter the treatment, acne scars in (Side A) showed 70 percent overall improvement versus zero percent in Side B (P<0.0001). A statistically highly significant reduction of acne scars severity occurred in (Side A) (P=0.0008). Patient’s satisfaction was higher in (Side A) (P<0.0001). No serious side effects were reported.ConclusionMicroneedling delivery of BTX-A could be simple, safe, and innovative modality improving the appearance and decrease the depth of atrophic acne scars.     

Invasive Lobular Carcinoma Has Worse Outcome Compared with Invasive Ductal Carcinoma in Stage IV Breast Cancer with Bone-Only Metastasis

BackgroundInvasive lobular carcinoma (ILC) is more likely to have bone metastasis than invasive ductal carcinoma (IDC). However, the prognosis for bone metastasis in ILC and IDC is barely known. So, the aim of this study was to investigate the difference of prognosis between ILC and IDC accompanied by bone metastasis.MethodsWe evaluated the women with bone-only metastasis of defined IDC or ILC reported to the Surveillance, Epidemiology and End Results program from 2010 to 2016. Pearson''s χ² test was used to compare the differences of clinicopathologic factors between IDC and ILC. Univariate and multivariate analyses were performed to verify the effects of histological types (IDC and ILC) and other clinicopathologic factors on the overall survival (OS) and cancer-specific survival (CSS).ResultsOverall, 3,647 patients with IDC and 945 patients with ILC met the inclusion criteria and were analyzed in our study. The patients with ILC were more likely to be older and to have lower histological grade and a higher proportion of the HR*/HER2− subtype. However, less treatment was administered to ILC than IDC, such as surgery of the breast, radiation, and chemotherapy. Compared to patients with IDC, patients with ILC showed worse OS (median OS, 36 and 42 months, respectively, p < 0.001) and CSS (median CSS, 39 and 45 months, respectively, p < 0.001), especially in subgroups with HR*/HER2− subtype (OS, hazard ratio: 1.501, 95% CI 1.270–1.773, p < 0.001; CSS, hazard ratio: 1.529, 95% CI 1.281–1.825, p < 0.001), lower histological grade (I–II) (OS, hazard ratio: 1.411, 95% CI 1.184–1.683, p < 0.001; CSS, hazard ratio: 1.488, 95% CI 1.235–1.791, p < 0.001), or tumor burden, such as T_0–2 (OS, hazard ratio: 1.693, 95% CI 1.368–2.096, p < 0.001; CSS, hazard ratio: 1.76, 95% CI 1.405–2.205, p < 0.001) and N_1–2 (OS, hazard ratio: 1.451, 95% CI 1.171–1.799, p = 0.001; CSS, hazard ratio: 1.488, 95% CI 1.187–1.865, p = 0.001). Furthermore, older age, black race, unmarried status, higher tumor burden (T_3–4 and N₃), triple-negative subtype, and higher histological grade were independent risk factors for both OS and CSS. Surgery of the breast and chemotherapy could significantly improve the prognosis for patients.ConclusionPatients with ILC have worse outcomes compared to those with IDC when associated with bone-only metastasis, especially in subgroups with lower histological grade or tumor burden. More effective treatment measures may be needed for ILC, such as cyclin-dependent kinase 4/6 inhibitors, new targeted drugs, etc.     

Combination Surgical Lifting with Ablative Laser Skin Resurfacing of Facial Skin: A Retrospective Analysis

BACKGROUND: Cutaneous aging is manifested by rhytides, dyschromias, and skin laxity. Ablative laser skin resurfacing can effectively improve many signs of skin aging; however, the photoaged patient with facial laxity often requires a surgical lifting procedure in order to obtain optimal results. Concerns with delayed or impaired wound healing has led to reluctance to perform both procedures simultaneously. OBJECTIVE: To report the clinical results and side effect profiles after concomitant surgical facial lifting procedures and ablative carbon dioxide or erbium:YAG laser resurfacing in a series of patients. METHODS: A retrospective analysis and chart review was performed in 34 consecutive patients who underwent combination CO(2) or erbium:YAG laser skin resurfacing and surgical lifting procedures, including S-lift rhytidectomy, blepharoplasty, and brow lift. Side effects and complication rates were tabulated. RESULTS: The side effect profile of the combined surgical-laser procedures was similar to that reported after a laser-only procedure. The most common side effect was transient hyperpigmentation which occurred in 20.6% of treated patients. None of the patients experienced delayed reepithelialization, skin necrosis, or prolonged healing times. CONCLUSIONS: Concurrent laser skin resurfacing and surgical lifting of facial skin maximizes aesthetic results without increased incidence of adverse effects. Patients benefit from the consolidation of anesthesia and convalescent times as well as enhanced global clinical outcomes.     

Four-Corner Arthrodesis versus Proximal Row Carpectomy: Risk Factors and Complications Associated with Prolonged Postoperative Opioid Use

Introduction  This article compares opioid use patterns following four-corner arthrodesis (FCA) and proximal row carpectomy (PRC) and identifies risk factors and complications associated with prolonged opioid consumption. Materials and Methods  The PearlDiver Research Program was used to identify patients undergoing primary FCA (Current Procedural Terminology [CPT] codes 25820, 25825) or PRC (CPT 25215) from 2007 to 2017. Patient demographics, comorbidities, perioperative opioid use, and postoperative complications were assessed. Opioids were identified through generic drug codes while complications were defined by International Classification of Diseases, Ninth and Tenth Revisions, Clinical Modification codes. Multivariable logistic regressions were performed with p < 0.05 considered statistically significant. Results  A total of 888 patients underwent FCA and 835 underwent PRC. Three months postoperatively, more FCA patients (18.0%) continued to use opioids than PRC patients (14.7%) ( p = 0.033). Preoperative opioid use was the strongest risk factor for prolonged opioid use for both FCA (odds ratio [OR]: 4.91; p < 0.001) and PRC (OR: 6.33; p < 0.001). Prolonged opioid use was associated with an increased risk of implant complications (OR: 4.96; p < 0.001) and conversion to total wrist arthrodesis (OR: 3.55; p < 0.001) following FCA. Conclusion  Prolonged postoperative opioid use is more frequent in patients undergoing FCA than PRC. Understanding the prevalence, risk factors, and complications associated with prolonged postoperative opioid use after these procedures may help physicians counsel patients and implement opioid minimization strategies preoperatively.     

Safety and efficacy of botulinum toxin type A in preventing and treating scars in animal models: A systematic review and meta‐analysis

Previous studies have used botulinum toxin type A (BTXA) to improve postoperative and hypertrophic scars; however, there is lack of detailed verification on the safety and effectiveness of this approach. This study aimed to evaluate the therapeutic effect of BTXA on postoperative hypertrophic scars and its influence on cytokine expression in animal models. A computerised search of different databases was performed, including PubMed, Web of Science, Scopus, Cochrane, Embase, CNKI, and Wanfang, up to 10 March 2021. A meta‐analysis was performed using R 4.0.0 based on hypertrophic index, epithelialisation time, wound area, and vascular endothelial growth factor (VEGF) expression. Eleven studies were included. The meta‐analysis showed a significant difference in hypertrophic index (standardised mean difference [SMD] = −2.63, 95% confidence interval [CI]: −3.50 to −1.76, P < .01), wound area (SMD = −0.54, 95% CI: −1.24 to 0.16, P < .01), and VEGF expression (SMD = −2.56, 95% CI: −3.50 to −1.62, P < .01). This study shows that BTXA is safe and effective in preventing and treating scar hypertrophy in animal models, but excessive doses of BTXA and BTXA to treat large areas should be avoided.     

Tacrolimus versus cyclophosphamide for patients with idiopathic membranous nephropathy and treated with steroids: a systematic review and meta-analysis of randomized controlled trials

BackgroundThe therapeutic effects of tacrolimus (TAC) versus cyclophosphamide (CTX) were not fully illustrated for patients with idiopathic membranous nephropathy (IMN).MethodsThe PubMed, EmBase, Cochrane library, and CNKI were systematically searched throughout March 2020 for randomized controlled trials evaluating the therapeutic effects of TAC versus CTX for IMN patients treated with steroids. The pooled relative risks (RRs) and weighted mean differences (WMDs) with 95% confidence intervals (CIs) were calculated using the random-effects model.ResultsTwelve trials recruited a total of 868 IMN patients were identified and contained in final meta-analysis. Patients in TAC group was associated with an increased incidence of overall remission (12 trials: 868 patients; RR: 1.21; 95% CI: 1.11–1.31; p < 0.001) and complete remission (12 trials: 868 patients; RR: 1.50; 95% CI: 1.25–1.80; p < 0.001). Moreover, we noted TAC therapy significantly reduced urinary protein excretion (9 trials: 567 patients; WMD: −1.06; 95%CI: −1.41 to −0.71; p < 0.001), and increased serum albumin (9 trials: 567 patients; WMD: 5.37; 95%CI: 2.97 to 7.77; p < 0.001) than CTX therapy. Furthermore, no significant difference between TAC and CTX for serum creatinine was detected (6 trials: 378 patients; WMD: 0.15; 95%CI: −3.46 to 3.75; p = 0.936). Finally, the risk of alopecia (p = 0.008), infection (p = 0.045), leukocytosis (p = 0.002), and elevated ALT/AST (p = 0.011) in TAC group was significantly lower than CTX group, whereas TAC was associated with an increased risk of tremor than CTX (p = 0.010).ConclusionsThis study found IMN patients treated with TAC combined with steroids provides a better therapeutic effect and less adverse events than those treated with CTX combined with steroids, with moderate-certainty evidence.     

Monocyte-to-lymphocyte ratio: a potential novel predictor for acute kidney injury in the intensive care unit

Monocyte-to-lymphocyte ratio (MLR) and neutrophil-to-lymphocyte ratio (NLR) are considered as surrogate inflammatory indexes. Previous studies indicated that NLR was associated with the development of septic acute kidney injury (AKI). The objective of the present study was to explore the value of MLR and NLR in the occurrence of AKI in intensive care unit (ICU) patients. The clinical details of adult patients (n = 1500) who were admitted to the ICU from January 2016 to December 2019 were retrospectively examined. AKI was diagnosed according to the Kidney Disease: Improving Global Outcomes criteria. The development of AKI was the main outcome, and the secondary outcome was in-hospital mortality. Overall, 615 (41%) patients were diagnosed with AKI. Both MLR and NLR were positively correlated with AKI incidence (p < 0.001). Multivariate logistic regression analysis suggested that the risk value of MLR for the occurrence of AKI was nearly three-fold higher than NLR (OR = 3.904, 95% CI: 1.623‒9.391 vs. OR = 1.161, 95% CI: 1.135‒1.187, p < 0.001). The areas under the receiver operating characteristic curve (AUC) for MLR and NLR in the prediction of AKI incidence were 0.899 (95% CI: 0.881‒0.917) and 0.780 (95% CI: 0.755‒0.804) (all p < 0.001), with cutoff values of 0.693 and 12.4. However, the AUC of MLR and NLR in the prediction of in-hospital mortality was 0.583 (95% CI: 0.546‒0.620, p < 0.001) and 0.564 (95% CI: 0.528‒0.601, p = 0.001). MLR, an inexpensive and widely available parameter, is a reliable biomarker in predicting the occurrence of AKI in ICU patients.     

Reasons for late presentation to HIV care in Switzerland

Introduction

Late presentation to HIV care leads to increased morbidity and mortality. We explored risk factors and reasons for late HIV testing and presentation to care in the nationally representative Swiss HIV Cohort Study (SHCS).

Methods

Adult patients enrolled in the SHCS between July 2009 and June 2012 were included. An initial CD4 count <350 cells/µl or an AIDS-defining illness defined late presentation. Demographic and behavioural characteristics of late presenters (LPs) were compared with those of non-late presenters (NLPs). Information on self-reported, individual barriers to HIV testing and care were obtained during face-to-face interviews.

Results

Of 1366 patients included, 680 (49.8%) were LPs. Seventy-two percent of eligible patients took part in the survey. LPs were more likely to be female (p<0.001) or from sub-Saharan Africa (p<0.001) and less likely to be highly educated (p=0.002) or men who have sex with men (p<0.001). LPs were more likely to have their first HIV test following a doctor''s suggestion (p=0.01), and NLPs in the context of a regular check-up (p=0.02) or after a specific risk situation (p<0.001). The main reasons for late HIV testing were “did not feel at risk” (72%), “did not feel ill” (65%) and “did not know the symptoms of HIV” (51%). Seventy-one percent of the participants were symptomatic during the year preceding HIV diagnosis and the majority consulted a physician for these symptoms.

Conclusions

In Switzerland, late presentation to care is driven by late HIV testing due to low risk perception and lack of awareness about HIV. Tailored HIV testing strategies and enhanced provider-initiated testing are urgently needed.     

The Usefulness of the Pretreatment Neutrophil/Lymphocyte Ratio as a Predictor of the 5-Year Survival in Stage 1–3 Triple Negative Breast Cancer Patients

BackgroundWe have previously shown that the neutrophil/lymphocyte ratio (NLR) is a predictor of survival among breast cancer patients. The aim of this study was to determine the predictive value of NLR among different nodal and chemotherapy subgroups of triple negative breast cancer (TNBC).MethodsPatients with stage 1–3 TNBC who underwent treatment from 2007 to 2014 and had blood counts prior to treatments were included. Patients were categorized into high (≥2) and low (<2) NLR groups. Primary outcomes were overall survival (OS) and disease-free survival (DFS).ResultsThe average follow-up time was 54 months. The high NLR group had worse OS (HR 2.8, CI 1.3–5.9, p < 0.001) and DFS (HR 2.3, CI 1.2–4.2, p < 0.001) than the low NLR group. After adjusting for confounding variables, high NLR was an independent prognostic factor for both OS (HR 5.5, CI 2.2–13.7, p < 0.0001) and DFS (HR 5.2, CI 2.3–11.6, p < 0.0001). Categorization of TNBC patients by NLR (high vs. low) and nodal status (positive vs. negative) resulted in four groups with significantly different OS and DFS (log rank p < 0.0001). Significant improvements in OS (p < 0.001) and DFS (p < 0.001) were observed for patients who received chemotherapy and had high NLR but not for patients with low NLR (p = 0.65 and p = 0.07, respectively).ConclusionHigh pretreatment NLR is an independent predictor of poor OS and DFS among TNBC patients. Combining NLR and pN provides better risk stratification for TNBC patients. Chemotherapy appears to be beneficial only in patients with high NLR. Larger prospective studies are needed to validate these findings.     

Effect of Single-Dose Preemptive Systemic Dexamethasone on Postoperative Dysphagia and Odynophagia Following Anterior Cervical Spine Surgery: A Double-Blinded,Prospective, Randomized Controlled Trial

BackgroundThe efficacy of preoperative dexamethasone in anterior cervical discectomy and fusion (ACDF) to reduce dysphagia and odynophagia remains controversial. This study evaluated the effect of a single dose of intravenous dexamethasone given as preemptive analgesia in the ACDF procedure.MethodsA total of 64 patients aged 18 years or over were randomized into two groups. The experimental group received dexamethasone 10 mg intravenously before surgery for 60 minutes, and the control group received normal saline. One surgeon operated on all patients. The Bazaz score and visual analog scale (VAS) for odynophagia were measured at 0 hour, 24 hours, 48 hours, 72 hours, and 2 weeks postoperatively. Prevertebral soft-tissue swelling (PSTS) and the modified Japanese orthopedic association (mJOA) score were measured preoperatively and 2 weeks postoperatively.ResultsThe Bazaz scores at 0, 24, 48, and 72 hours after operation were significantly lower in the dexamethasone group than in the placebo group (p < 0.001, p < 0.001, p < 0.001, and p = 0.004, respectively). The VAS scores of the dexamethasone group were significantly lower than those of the placebo group at 0, 24, 48, and 72 hours after surgery (all p < 0.001), but there was no significant reduction in the Bazaz score and VAS score at 2 weeks postoperatively. There was no difference in PSTS and mJOA preoperatively and 2 weeks postoperatively.ConclusionsA single dose of intravenous dexamethasone used preoperatively in single-level and multilevel ACDF can significantly improve symptoms of dysphagia and odynophagia early on postoperatively.     

Correlation Between the Evaluation of Pigmented Lesions by a Multi-spectral Digital Skin Lesion Analysis Device and the Clinical and Histological Features of Melanoma

Objective: To correlate Multi-spectral Digital Skin Lesion Analysis classifier scores with histopathological severity of pigmented lesions and clinical features of melanoma. Design: Classifier scores were computed for 1,632 skin lesions. Dermatologists evaluated the same lesions for Asymmetry, Border Irregularity, Color variegation, Diameter >6mm, Evolution, Patient’s Concern, Regression, and/or “Ugly Duckling” sign. Classifier scores were correlated to the number of clinical risk features and for six histopathological severity levels of pigmented lesions. Measurements: Average classifier score, Welch’s t-test, and chi-square analysis. Results: Melanomas had higher mean classifier scores (3.5) than high-grade dysplastic nevi (2.7, p=0.002), low-grade dysplastic nevi (1.7, p<0.0001), non-dysplastic nevi (1.6, p<0.0001), and benign non-melanocytic lesions (2.0, p<0.0001). Classifier score and the number of clinical risk characteristics directly correlated (Pearson coefficient 0.32, p<0.0001). Conclusion: Correlation of classifier scores to clinical and histological melanoma features supports the effectiveness of Multi-spectral Digital Skin Lesion Analysis in assessing the risk of pigmented lesions requiring biopsy. Optimizing outcomes of dermatologist decisions to biopsy suspicious pigmented lesions may be enhanced utilizing Multi-spectral Digital Skin Lesion Analysis.The incidence of malignant melanoma has increased an average of four percent per year in the United States since the early 1970s.1 Today, over one American dies every hour from melanoma.2 Detected in its earliest stage, melanoma is almost completely curable with simple excision. However, the five-year survival rate drops to <10 percent with stage IV disease. Therefore, the key challenge for early diagnosis is to determine which atypical pigmented skin lesions require biopsy. Technology has been shown to augment the biopsy decision accuracy of dermatologists evaluating suspicious pigmented lesions.3Multi-spectral Digital Skin Lesion Analysis (MSDSLA, MELA Sciences Inc, Irvington, New York) uses narrow bands of visual and near-infrared light (430-950nm) to capture data from the skin surface down to 2.5mm in depth. At a 20-micron resolution (~diameter of 3 melanocytes), individual cellular atypia is not evaluable by MSDSLA. Instead, the device uses 75 analytical parameters to determine the level of morphological disorder within an atypical pigmented skin lesion to generate a classifier score (CS).3 Using the CS, MSDSLA provides objective data that can be integrated into the dermatologist’s biopsy decision. Knowledge of the CS was shown to improve the average biopsy sensitivity for melanoma of 179 dermatologists from 69 to 94 percent (p<0.001).4The purpose of this study was to further characterize the MSDSLA CS for levels of histologic severity of atypical and banal pigmented lesions and its level of correlation to independently evaluated clinical features of the same lesions.     

The optimal time for surgery in women with serous ovarian cancer

BackgroundAdvanced high-grade serous ovarian carcinoma (HGSC) is commonly treated with surgery and chemotherapy. We investigated the survival of patients treated with primary or interval surgery at different times following neoadjuvant chemotherapy. Their survival was compared with that of patients treated with primary cytoreductive surgery and adjuvant chemotherapy.MethodsPatients with stage III or IV HGSC were included in this retrospective cohort study. Clinical data were obtained from patient records. Patients were divided into 2 groups based on treatment with neoadjuvant chemotherapy and interval cytoreductive surgery (NAC) or with primary cytoreductive surgery and adjuvant chemotherapy (PCS). Study groups were stratified by several clinical variables.ResultsWe included 334 patients in our study: 156 in the NAC and 178 in the PCS groups. Survival of patients in the NAC group was independent of when they underwent interval cytoreductive surgery following initiation of neoadjuvant chemotherapy (p < 0.001). Optimal surgical cytoreduction had no impact on overall survival in the NAC group (p < 0.001). Optimal cytoreduction (p < 0.001) and platinum sensitivity (p < 0.001) were independent predictors of improved survival in the PCS but not in the NAC group. Patients in the NAC group had significantly worse overall survival than those in the PCS group (31.6 v. 61.3 mo, p < 0.001).ConclusionWomen with advanced HGSC who underwent PCS had better survival than those who underwent interval NAC, regardless of the number of cycles of neoadjuvant therapy. Optimal cytoreduction did not provide a survival advantage in the NAC group.     

Anxiety and depression are common in rheumatoid arthritis and correlate with poor quality of life in Indian patients

ObjectivesWe planned this study to assess the prevalence of anxiety and depression in rheumatoid arthritis (RA) patients and its correlation with quality of life (QOL) in these patients.Material and methodsEighty-eight patients (76 females) were included in this cross-sectional study. The Hospital Anxiety and Depression Scale (HADS) was used to assess anxiety and depression. Quality of life was measured using the World Health Organization WHOQOL-BREF. The severity of pain was measured by 100-millimetre-long Visual Analogue Scale (VAS), and functional disability was measured by using the Indian version of the Health Assessment Questionnaire (HAQ). The disease activity was measured by Disease Activity Score for 28 joints with 3 variables.ResultsProbable anxiety and depression were seen in 61 (69%) and 68 (77%) of the patients, respectively. Patients with anxiety had more severe pain (VAS 53.8 ±26.4 vs. 39.7 ±26.1, p < 0.05), and significantly lower scores in all the 4 domains of the WHOQOL-BREF. Patients with depression had more pain (VAS 54.2 ±25.2 vs. 33.5 ±27.3, p < 0.01), higher HAQ scores (1.0 ±0.7 vs. 0.5 ±0.7, p < 0.01), and lower QOL scores. Both anxiety and depression scores had a negative correlation with all the 4 domains of the WHOQOL-BREF. Anxiety had a significant negative effect on psychological (β = –0.58, p < 0.001) and environmental domains (β = –0.39, p < 0.001), while depression had a significant negative effect on psychological (β = –0.57, p < 0.001) and environmental domains (β = –0.53, p < 0.001). Both anxiety and depression predicted more pain in RA patients (β = 0.24, p < 0.001 and β = 0.44, p < 0.001, respectively).ConclusionsAnxiety and depression correlated with poor QOL in all 4 domains of the WHOQOL-BREF. Higher HADS scores had a negative effect on all the domains of the WHOQOL-BREF and predicted more severe pain in RA patients. Thus, patients with RA need to be screened and treated for underlying anxiety and depression to improve their QOL, pain, and functional status.
