Safety of infraorbital hyaluronic acid injections: Outcomes of a meta-analysis on prospective clinical trials.

BACKGROUND: Hollowing of the infraorbital region represents a common concern among aesthetic patients. In the past decade, an increasing number of patients have resorted to noninvasive aesthetic procedures to treat these concerns. The objective of this study was to evaluate the safety profile of infraorbital hyaluronic acid injections for aesthetic rejuvenation. METHODS: Through a systematic review and meta-analysis of prospective clinical trials, investigators sought to answer the research question "Does the use of needle versus cannula during infraorbital HA injections result in the same incidence rate of adverse events?" The primary outcomes of interest were the incidence rates of ecchymosis and edema in subject groups treated with a needle or cannula. RESULTS: Subjects treated with needles had a statistically significant greater incidence rate of ecchymosis, compared to those treated with cannula. Conversely, subjects treated with cannula had a statistically significant greater incidence rate of edema, compared to those treated with needles. CONCLUSIONS: The incidence rates of adverse events following the administration of hyaluronic acid injections in the infraorbital region vary depending on whether a needle or cannula is used; with needles being associated with a greater risk of ecchymosis and cannulas being associated with a greater risk of edema. These findings should be discussed with patients prior to treatment consultation. Finally, as with most techniques, it is usually prudent to develop expertise with one technique before using a second, especially in cases where both approaches can be used and have different adverse event profiles.

Clinical predictors of early surgical intervention in patients with venomous snakebites.

BACKGROUND: Venomous snakebites induce tissue destruction and secondary infection; however, the optimal timing of surgical intervention for these complications remains unknown. This study assessed the clinical predictors of early surgical intervention in patients with snakebites. METHODS: This retrospective study included 63 patients (45 men and 18 women) with venomous snakebites. In addition to the snake species, the demographics, affected body parts, clinical characteristics, and ultrasound findings of the patients in the surgical (32 patients) and nonsurgical (31 patients) groups were analyzed and compared. RESULTS: A higher incidence of acute compartment syndrome, local ecchymosis, skin necrosis, bullae, blisters, and fever was found in the surgical group than in the nonsurgical group, and ultrasound findings of the absence of Doppler flow were more frequently noted in the surgical group than in the nonsurgical group. After adjustment using a multivariate logistic regression model, only advanced age, Naja atra bite, local ecchymosis, and bulla or blister formation remained significant factors for surgical intervention. Furthermore, comparison of the outcomes of patients who received early (≤ 24 h) and late (> 24 h) surgical intervention revealed that the duration of continuous negative pressure wound therapy (6 vs. 15 days; P = 0.006), duration of hospital stay (13 vs. 26 days; P = 0.002), and duration of outpatient follow-up (15 vs. 36 days; P < 0.001) were significantly lower in patients who received early surgical intervention. The final reconstructive surgery was simple among the patients who received surgical intervention within 24 h of being bitten (P = 0.028). CONCLUSION: In patients with snakebites, advanced age, high-risk clinical manifestations (e.g., local ecchymosis and bulla or blister formation), and Naja atra envenomation are predictors of surgical intervention within 24 h.

Improving forensics: Characterizing injuries among community-dwelling physically abused older adults.

BACKGROUND: Physical elder abuse affects a substantial number of older adults, leaving victims at increased risk for negative health outcomes. Improved detection of abuse-related injuries may increase victim access to professional support, but providers report difficulties distinguishing between accidental and abuse-related injuries, due in part to victims' pre-existing health conditions and medication use. OBJECTIVES: To describe the spectrum and characteristics of injuries among physically abused older adults and identify injury characteristics associated with abuse. DESIGN: Case-control study. SETTING: Physically abused adult protective services clients were interviewed in their home; non-abused comparison group participants were interviewed in an outpatient geriatrics clinic. PARTICIPANTS: Sample included 156 community-dwelling adults aged 65 and older, including 57 physically abused and 99 non-abused individuals. Self-reported abuse history was confirmed through independent case assessment by a LEAD (Longitudinal, Expert All-Data) panel of clinicians with family violence expertise. MEASUREMENTS: Full-body assessments were conducted, documenting injury incidence, diagnosis, and location. We also collected sociodemographic characteristics, level of social support, functional ability, medical history, and medication use. RESULTS: Physically abused older adults were more likely to be injured upon assessment (79.0% vs 63.6%; p < 0.05) and have a greater number of injuries ( x¯=2.9 vs x¯=2.0 , p < 0.05). Injuries seen more often among abused individuals included: upper extremity ecchymoses (42.1% vs 26.3%; p < 0.05), abrasions (31.6% vs 11.1%; p < 0.01), and areas of tenderness (8.8% vs 0.0%; p < 0.01); and head/neck/maxillofacial ecchymoses (15.8% vs 2.0%; p < 0.01) and tenderness (15.8% vs 0.0%; p < 0.001). Lower extremity abrasions (12.3%) were common but unrelated to abuse status. CONCLUSION: While physical abuse does not always result in physical injury, victims more commonly display head/neck/maxillofacial ecchymoses or tenderness and upper extremity abrasions, ecchymoses, or tenderness. Detection of these injuries among older adults warrants further interview and examination.

Comparison Between Cyanoacrylate Embolization and Radiofrequency Ablation for Superficial Venous Incompetence: A Systematic Review and Meta-analysis.

BACKGROUND: Chronic venous disease is a debilitating condition involving great saphenous vein (GSV) incompetence. OBJECTIVE: To investigate the efficacy and effectiveness of cyanoacrylate embolization (CAE) versus radiofrequency ablation (RFA) in patients with incompetent GSVs. MATERIALS AND METHODS: PubMed, Embase, and the Cochrane library were searched. The primary outcomes were the Venous Clinical Severity Score (VCSS), Aberdeen Varicose Vein Questionnaire (AVVQ), closure rate, and visual analog scale (VAS) for pain. RESULTS: This meta-analysis included 378 and 590 patients who underwent CAE and RFA, respectively. Cyanoacrylate embolization was comparable with RFA in VCSS (weighted mean difference [WMD] = -0.03, 95% confidence interval [CI]: -0.18 to 0.12, p = .686), AVVQ (WMD = -0.08, 95% CI: -0.38 to 0.21, p = .570), closure rate (odds ratio [OR] = 0.61, 95% CI: 0.18-2.01, p = .414), and VAS (standardized mean difference [SMD] = 0.24, 95% CI: -0.59 to 1.06, p = .523). There were no significant differences between CAE and RFA regarding the occurrence of phlebitis (OR = 1.22, 95% CI: 0.70-2.13, p = .479) and pigmentation (OR = 0.48, 95% CI: 0.18-1.31, p = .153), but CAE had a lower risk of ecchymosis (OR = 0.45, 95% CI: 0.25-0.81, p = .007) and paresthesia (OR = 0.16, 95% CI: 0.03-0.99, p = .049). CONCLUSION: Cyanoacrylate embolization and RFA demonstrated no significant differences in VCSS, AVVQ, closure rate, and pain score for patients with incompetent GSVs. Patients in the CAE group had a lower risk of ecchymosis and paresthesia compared with the RFA group.

Anesthesia using microcannula and sharp needle in upper blepharoplasty: A randomized, double-blind clinical trial evaluating pain, bruising, and ecchymoses.

INTRODUCTION: With the emergence of blunt-tipped microcannulas, there is a hypothesis that these could cause less damage and reduce pain as compared to conventional sharp needles in eyelid surgery. The purpose is to determine whether an 18G blunt-tipped cannula can be better than a 26G needle. METHODS: This prospective, observer-blinded, randomized clinical trial was conducted from June 2017 to December 2018. Sixty-eight patients were randomized to receive local anesthesia injections for upper blepharoplasty. Infiltration was performed by using a 26-gauge sharp needle on one side and on the other side, infiltration was performed by using an 18-gauge stainless-steel blunt-tipped microcannula. A numeric rating scale (NRS) from 0 to 10 was used to blindly assess pain in patients receiving anesthesia injections with both needle types. Photographs of the eyelids of each patient were taken in five different periods and used by three blinded observers to identify bruise or ecchymoses. RESULTS: A total of 136 eyelid operations were performed. There was no statistically significant difference when both groups were compared; however, the average score of pain was higher in patients taking the infiltration through the needle (2.85 versus 2.50). Regarding the evaluation of bruising and ecchymoses, the results showed that, in the five periods evaluated, there was no statistical difference in bruising and ecchymosis in the eyelids when taking the infiltration through a sharp needle when compared with that of the eyelids taking infiltration through a (blunt-tipped) microcannula. CONCLUSION: The evaluation of the blunt-tipped microcannula showed a lower pain score mean than that obtained for the sharp needle (2.5 versus 2.85) (p > 0.05). There was no statistically significant difference in the bruising and ecchymosis courses.

Dermatological Toxicities of Bruton's Tyrosine Kinase Inhibitors.

The development of Bruton's tyrosine kinase (BTK) inhibitors represents a major breakthrough in the treatment of chronic lymphocytic leukemia and other B cell malignancies. The first-generation inhibitor ibrutinib works by covalent irreversible binding to BTK, a non-receptor tyrosine kinase of the TEC (transient erythroblastopenia of childhood) family that plays a critical role in the B-cell receptor signaling pathway. It also induces an 'off-target' inhibition of a range of other kinases including (but not limited to) epidermal growth factor receptor (EGFR), SRC, and other kinases of the TEC family (interleukin-2-inducible T-cell kinase [ITK], Tec, BMX). Dermatological toxicities are among the most common toxicities of ibrutinib, but remain of mild to moderate intensity in most cases and are readily manageable. Their incidence is highest during the first year of treatment and declines over time. In addition, it has been postulated that ibrutinib-related dermatologic adverse events are mediated by the direct binding to both BTK and other 'off-target' kinases. Bruising, ecchymoses, and petechiae represent the most characteristic dermatologic adverse events. Nail and hair changes are also common, as skin infections (opportunistic infections including herpes simplex and herpes zoster virus reactivations, and Staphylococcus aureus superinfection), folliculitis, and other types of rashes. Panniculitis, aphthous-like ulcerations with stomatitis, neutrophilic dermatosis, peripheral edema, and skin cracking can also occur. Next-generation BTK inhibitors, acalabrutinib and zanubrutinib, have been designed to optimize BTK inhibition and minimize off-target inhibition of alternative kinases (Tec, ITK, EGFR, SRC-family kinases). These drugs have been recently FDA-approved for relapsed or refractory mantle cell lymphoma. Although the overall incidence of their toxicities is expected to be more limited, acalubrutinib and zanubrutinib are associated with a range of dermatologic toxic effects that appear to be similar to those previously described with ibrutinib, including bruising and ecchymoses, panniculitis, human herpesvirus infections, cellulitis, and skin rash. In particular, both drugs induce skin bleeding events in more than 30% of patients treated. However, the available dermatological data are still rather limited and will have to be consolidated prospectively. This review article analyses the wide spectrum of dermatological toxicities that can be encountered with first- and second-generation BTK inhibitors. Finally, recommendations for appropriate treatment as well as a synthesis algorithm for management are also proposed.

Comparing the Efficacy of Radiofrequency Ablation Versus Laser Ablation for Chronic Venous Insufficiency in the Lower Extremities: a Vietnamese Report.

INTRODUCTION: Chronic venous insufficiency (CVI) is a chronic condition, triggered by reflux through the saphenous vein network. AIM: To determine the efficacy of endovenous laser ablation (LA) and radiofrequency ablation (RFA) for CVI treatment in the lower extremities, at the Bach Mai Radiology Center. METHODS: This retrospective study was approved by the institutional review board of Bach Mai Hospital. The study recruited 49 people, from August 2016 to April 2018, with recurrent venous insufficiency in the lower extremities and measured 56 ablated veins. RESULTS: In this study, 8 patients (10 veins, with a mean diameter of 5.83 ± 0.96 mm) were treated with RFA, and 41 patients (46 veins, with a mean diameter of 7.96 ± 3.47 mm) were treated with LA. The occlusion rates for LA- and RFA-treated veins were very effective, at 95.7% and 90%, respectively. No significant differences in occlusion rates or clinical improvements were observed between the two ablation methods. On the first day post-treatment, the visual analog score (VAS) value for the LA group was significantly higher than that for the RFA group. Furthermore, ecchymosis, 1 day after treatment, and hyperpigmentation, paresthesia, and numbness, 1 month after treatment, were only observed in the LA group. CONCLUSION: Both LA and RFA were minimally-invasive and safe therapies. No serious complications requiring further interventions were reported and the treatment effectively improved the clinical symptoms of patients. Based on our study, we recommend that RFA should be considered for moderate dilated saphenous vein cases, whereas LA should be indicated for large dilated saphenous vein cases, with or without aneurysm.

Ecchymosis combined with postinflammatory hyperpigmentation associated with acupuncture therapy: An observational study of 167 subjects.

To evaluate the incidence of ecchymosis combined with postinflammatory hyperpigmentation (ECPH) over the course of 10 sessions of acupuncture therapy and to examine associated factors.An observational study was conducted from March 7, 2017 through March 6, 2018. This study included a total of 167 subjects and 326 bodily locations where acupuncture needles had been inserted. A 1-page questionnaire that included 14 items was used to collect patient data. The information collected was used to determine the incidence of ECPH. Chi-square tests were used to observe the associations between ECPH and demographic characteristics, dermatologic features, acupuncture-related factors, and other associated factors. Cox proportional hazards regression models were applied to calculate hazard ratios for ECPH among subjects treated with various frequencies of acupuncture and needles that differed in diameter.Although 186 subjects were initially enrolled, the study ultimately included 167 subjects and 326 bodily locations at which acupuncture needles were inserted. Over 10 sessions of acupuncture, ECPH was observed in 117 (70.06%, 117/167) subjects and 221 (67.79%, 221/326) bodily locations. Factors found to be associated with ECPH included: frequency of acupuncture, diameter of acupuncture needle, total number of acupuncture sessions, and bodily location at which acupuncture was administered (P < .05). Among subjects who received >2 acupuncture sessions per week, a higher frequency of acupuncture was associated with increased incidence of ECPH. Thicker acupuncture needle diameter was associated with a higher incidence of ECPH.The incidence of acupuncture-associated ECPH among the subjects included in the study was high. There were significant associations between ECPH and higher frequency of acupuncture as well as thicker diameter of acupuncture needles. Additional studies are required to confirm the findings.Trial registration number: AMCTR-OOC-17000109.

Effect of piezoelectric osteotomy on postoperative oedema and ecchymosis after rhinoplasty.

OBJECTIVES: This study evaluated the efficacy of piezoelectric osteotomy in reducing oedema and ecchymosis during rhinoplasty via a systematic review with meta-analysis. DESIGN AND SETTING: Two authors independently searched the referenced databases. PubMed, Embase, SCOPUS, the Web of Science, the Cochrane library and Google Scholar databases were systematically searched from inception to January 2019. PARTICIPANTS: Sufficient data were retrieved for a meta-analysis of six trials with a total of 327 patients. MAIN OUTCOME MEASURES: They included studies that compared piezoelectric osteotomy (treatment groups) with conventional osteotomy (control group). The outcomes of interest were operative time, mucosal injury, oedema, ecchymosis and postoperative pain. Baseline study characteristics, quality of study, numbers of patients in the treatment and control groups and outcomes were extracted. RESULTS: Intraoperative mucosal injury was significantly lower in the treatment group vs the control group, but operative time was longer in the treatment group. Eyelid oedema and ecchymosis in the first seven days postoperatively were statistically decreased in the treatment group vs the control group. In addition, pain in the first three days postoperatively was statistically decreased in the treatment group vs the control group. However, in a subgroup analysis according to osteotomy visibility in the control group (blind osteotomy vs osteotomy under direct vision), there was no significant difference in oedema and ecchymosis between treatment and osteotomy under direct vision. CONCLUSIONS: Piezoelectric osteotomy during rhinoplasty can reduce eyelid oedema and eyelid ecchymosis compared to conventional osteotomy. However, piezoelectric osteotomy had no significant advantages in terms of postoperative oedema and ecchymosis compared to osteotomy under direct vision.

Comparative study between: Carboxytherapy, platelet-rich plasma, and tripolar radiofrequency, their efficacy and tolerability in striae distensae.

BACKGROUND: Striae distensae are very common cutaneous disorders that produce great psychological stress for women. OBJECTIVE: measure and compare between efficacy and tolerability of three modalities for treatment of striae distensae. PATIENTS AND METHODS: Forty-five female patients with striae distensae were randomly selected from the outpatient dermatology clinics of Al-Zahra university Hospital within 6 months period. Patients divided into three groups according to the therapeutic modalities were used. Group A: treated with carboxytherapy using carbon dioxide (CO2) injection, Group B: where patients were treated with intradermal injection of autologous platelet-rich plasma (PRP), and Group C: where we used tripolar radiofrequency (RF) for treatment. RESULTS: All treated groups showed overall clinical improvement as regards the width, texture, and overall improvement after treatment (P > .05), with no statistically significant differences between the three groups. Patient's satisfaction was statistically significantly better in both group C (93.33%) and group A (80%) while group B (53.33%) was less with minimal side effects such as pain and ecchymosis, which were more frequent in group B than the other two groups; but with no statistically significance differences both groups A and C were effective with no significant differences in both types of striae and in any site of the body but group B is significantly more effective on striae rubra on trunk, with better improvement of lesions texture. CONCLUSION: The three modalities of treatments proved to be effective clinically and histopathologically in treating both types of striae, which were well tolerated by the patients with minimal, transient side effects and our study results gave us guidelines for their clinical application.

Dermatological manifestations in hemodialysis patients in Iran: A systematic review and meta-analysis.

BACKGROUND: Dermatologic complications are common in patients with end-stage renal disease and also have a high diversity. OBJECTIVES: This meta-analysis reviews prevalence of dermatological manifestations among hemodialysis patients in Iran. MATERIALS AND METHODS: Using PubMed and NLM Gateway (for MEDLINE), Institute of Scientific Information (ISI), and SCOPUS as the main international electronic data sources, and Iran-Medex, Irandoc, and Scientific Information Database, as the main domestic databases with systematic search capability, we systematically searched surveys, papers, and reports on the prevalence of dermatological manifestations (until February 2016). Heterogeneity of reported prevalence's between studies was assessed using the Q test; overall prevalence of dermatological manifestations was estimated using random-effect meta-analysis model. RESULTS: We found 1229 records; from them, a total of eight studies comprising 917 hemodialysis patients were included. In all of studies, skin discoloration, pruritus and xerosis have the highest prevalence. According to random-effect meta-analysis model, the pooled prevalence of skin discoloration, pruritus, ecchymosis, xerosis, and half-and-half nail in hemodialysis patients were 48.03% (95% CI: 45.09-51.01), 52.85% (95%CI: 49.23-56.47), 19.88 (95% CI: 17.57-22.19), 51.14% (95% CI: 48.25-54.02), and 18.50% (95% CI: 16.0-21.0), respectively. CONCLUSIONS: his study shows that the prevalence of dermatological manifestations seems high among the hemodialysis patients in Iran, and skin discoloration, pruritus, and xerosis are more common.

Safety of omitting routine bleeding tests prior to image-guided musculoskeletal core needle biopsy.

PURPOSE: To evaluate the safety of withholding preprocedure international normalized ratio (INR) and platelet testing in patients undergoing musculoskeletal (MSK) core needle biopsy (CNB). MATERIAL AND METHODS: Initially, a retrospective review of 1,162 consecutive patients undergoing MSK CNB with preprocedural INR and platelet testing was performed. Clinical (age, gender, bleeding disorder, liver disease, anticoagulation use, INR > 2, platelet count <50,000/ul) and biopsy factors (imaging modality, lesion type, biopsy needle gauge, number biopsy samples) were tested for association with bleeding complications. During the second phase, an additional 188 biopsies performed without preprocedural coagulation testing were studied. Categorical variables were compared using Chi-squared or Fisher's exact tests, continuous variables with a student t-test. Multivariate analysis was performed using logistic regression. RESULTS: In the first phase, there was a complication rate of 2.6%, 30/1162. Of the 11 clinical and biopsy factors, soft tissue lesions (p = 0.029) and lesions biopsied under ultrasound (p = 0.048) had a higher rate of bleeding than bone lesions or lesions biopsied under CT, respectively. Only three patients had an INR >2, 0.3% (3/1162) and only four patients had platelet count <50,000/ul, 0.3% (4/1162). No patient with a bleeding complication had an abnormal preprocedure bleeding test. In the second phase, there was a bleeding complication rate of 1.1% (2/188). CONCLUSION: Bleeding complications from MSK biopsy are low, even when preprocedure coagulation testing is omitted.

Comparison of clinical outcomes using a Piezosurgery device vs. a conventional osteotome for lateral osteotomy in rhinoplasty.

Our aim for this study was to evaluate and compare the clinical outcomes in patients who underwent lateral osteotomy with a Piezosurgery device or a conventional osteotome in open-technique rhinoplasty. This cohort trial involved 65 patients (36 women and 29 men; average age: 23.6 ± 5.71 yr) who underwent surgery between May 2015 and January 2016. Piezosurgery was used for lateral osteotomy in 32 patients, whereas 33 patients underwent conventional external osteotomy. These 2 groups were compared for duration of surgery, perioperative bleeding, postoperative edema, ecchymosis, pain, and patient satisfaction on the first and seventh postoperative days. The Piezosurgery group revealed significantly more favorable outcomes in terms of edema, ecchymosis, and hemorrhage on the first day postoperatively (p < 0.001 for all). Similarly, edema (p = 0.005) and ecchymosis (p < 0.001) on the seventh postoperative day also were better in the Piezosurgery group. Hemorrhage was similar in both groups on the seventh postoperative day (p = 0.67). The Piezosurgery group not only experienced less pain on the first postoperative day (p < 0.001), but these patients also were more satisfied with their results on both the first and seventh postoperative days. Results of the present study imply that Piezosurgery may be a promising, safe, and effective method for lateral osteotomy, a critical step in rhinoplasty. The time interval necessary for the learning curve is counteracted by the comfort and satisfaction of both patients and surgeons.

Prevalence of skin tears in the extremities among elderly residents at a nursing home in Denmark.

OBJECTIVE: The aim of the study was to determine the prevalence of skin tears in the extremities and explore factors in relation to skin tears in elderly residents at a Danish nursing home. METHOD: The study was designed as a point prevalence survey and conducted at a nursing home with 140 residents >65 years of age. The residents were assessed for presence, number and location of skin tears. Data were collected using a data collection sheet developed for this study. The survey team consisted of four expert nurses from a university hospital (two dermatology and two wound care nurses). Data were collected over a period of 10 hours spread over two days. RESULTS: Of the 128 participating residents six had skin tears, yielding a prevalence of 4.6 %. In total, 10 skin tears were observed in the 6 residents. The frequency of previous skin tears was 19.5 %. This frequency was significantly higher in residents with skin tears than in those without skin tears (83.3 % versus 16.4 %, p<0.001). Analysis of the relation between skin tears or previous skin tears versus without skin tears or previous skin tears showed significant differences related to the presence of ecchymosis (76.9 %versus 14.7 %, p<0.0001). There were no other significant factors observed. CONCLUSION: The low prevalence found in this study may reflect the focus on prevention of skin tears that the nursing home has maintained over the past year. Nevertheless, the appropriate prevention and management of residents with skin tears is an ongoing challenge for health professionals.

Quantifying cutaneous adverse effects of systemic glucocorticoids in patients with rheumatoid arthritis: a cross-sectional cohort study.

OBJECTIVES: EULAR guidelines state that adverse effects (AEs) of glucocorticoid (GC) therapy should be considered and discussed with the patient before treatment is initiated. However, reliable quantitative data, especially on cutaneous AEs of low-to-medium dose GCs are lacking. We performed a study assessing the occurrence of cutaneous AEs of GCs and its association with current and cumulative GC doses in patients with rheumatoid arthritis (RA). METHODS: In a cross-sectional study performed in 2 outpatient rheumatology centres, 381 RA patients were enrolled. They were classed into 4 groups, according their mean daily dose during the past 12 months: 0 mg (n=87), <5mg (n=108), 5-7.5 mg (n=130), and >7.5 mg (n=56) of prednisone equivalent. AEs of GC on the skin were assessed by physical examination using a predefined scoring system, and by patients' self-assessments. Data were analysed according GC dose categories and cumulative doses. RESULTS: Cushingoid habitus, easy bruising, skin atrophy, and impaired wound healing as reported by patients occurred significantly more frequently in those using a GC the past 12 months, compared to those not using a GC. At physicians' assessments, only Cushingoid habitus and ecchymosis were more prevalent in GC users. The prevalence of these AEs was statistically significantly positively associated with current and cumulative GC dose. There was low occurrence of abnormal stretch marks, acne, perioral dermatitis, alopecia and hirsutism, which were not correlated with GC use. CONCLUSIONS: Certain GC-associated cutaneous AEs are common in RA, but other AEs of GC occur infrequently at the low-to-medium GC doses used in RA.

[Delayed adverse reactions to blood donation: From haemovigilance data to specific studies]. / Les effets indésirables retardés chez les donneurs de sang : des données de l'hémovigilance aux études spécifiques.

OBJECTIVES: Delayed adverse reactions to blood donation occur after the donor left donation site. Their intrinsic gravity and possible complications can be increased by the fact the donor is alone. This can also increase bad memories, leading to a donation giving up. Blood transfusion centre is only aware in case of donor feedback, hence an event underrating. We choose to compare our data upon delayed adverse donor reactions with those we could find in past studies. METHODS: A first data level comes from French haemovigilance data while serious adverse reactions declaration is mandatory. But a second level can be reached using blood transfusion centre computerized data because all the donation reactions are saved whatever the gravity is. In both cases, delayed reactions are only those reported by donors. We try to make an exhaustive search of specific studies upon the real delayed reactions incidence so as to compare with our data. RESULTS: There were 1957 serious adverse reactions declared in our regional haemovigilance database between 2011 and 2015: 49 % occurring during donation, 40 % after it but before donor departure, and 11 % delayed events. There were 16,050 adverse reactions recorded during the first trimester of 2016 in mainland France, with 2.7 % delayed ones. Proportion of delayed events rises when gravity rises, until 27.6 % for the most serious ones. It varies between 2.2 % and 2.7 % for vasovagal reactions, haematomas, and other local reactions, and reaches 16.2 % for other general reactions. Data found in other studies with a spontaneous donor notification are of the same kind. But four studies soliciting specifically donor notification give a dramatically higher delayed reactions incidence, with an understatement greater than three out of four. Moreover, these studies found a majority of delayed reactions, which are not included in haemovigilance like fatigue or bruising. CONCLUSIONS: Occurrence of a delayed donor reaction is clearly underrated in standard haemovigilance. It remains to be seen whether it have the same impact on donor return as immediate reactions. Considering that delayed reactions are much larger, it might be interesting to take them into account in the evaluation of strategies dedicated to lower immediate reactions.

Can surgical need in patients with Naja atra (Taiwan or Chinese cobra) envenomation be predicted in the emergency department?

OBJECTIVES: To investigate the clinical predictors and the aetiologies for surgery in patients with Naja atra (Taiwan or Chinese cobra) envenomation. METHODS: This case series was conducted in the only tertiary care centre in eastern Taiwan. Patients who presented to the emergency department with Naja atra bite between January 2008 and September 2014 were included. Clinical information was collected and compared between surgical and non-surgical patients. RESULTS: A total of 28 patients with Naja atra envenomation presented to the emergency department during the study period. Of these, 60.7% (n=17) required surgery. Necrotising fasciitis (76.5%) was the main finding in surgery. Comparisons between surgical and non-surgical patients showed skin ecchymosis (odds ratio=34.36; 95% confidence interval, 2.20-536.08; P=0.012) and a high total dose of antivenin (≥6 vials; odds ratio=14.59; 95% confidence interval, 1.10-192.72; P=0.042) to be the most significant predictors of surgery. The rate of bacterial isolation from the surgical wound was 88.2%. Morganella morganii (76.5%), Enterococcus faecalis (58.8%), and Bacteroides fragilis (29.4%) were the most common pathogens involved. Bacterial susceptibility testing indicated that combined broad-spectrum antibiotics were needed to cover mixed aerobic and anaerobic bacterial infection. CONCLUSIONS: Patients with Naja atra envenomation who present with skin ecchymosis or the need for a high dose of antivenin may require early surgical assessment. Combined broad-spectrum antibiotics are mandatory.

Spontaneous extracranial hemorrhagic phenomena in primary headache disorders: A systematic review of published cases.

Background Head pain is a cardinal feature of primary headache disorders (PHDs) and is often accompanied by autonomic and vasomotor symptoms and/or signs. Spontaneous extracranial hemorrhagic phenomena (SEHP), including epistaxis, ecchymosis, and hematohidrosis (a disorder of bleeding through sweat glands), are poorly characterized features of PHDs. Aim To critically appraise the association between SEHP and PHDs by systematically reviewing and pooling all reports of SEHP associated with headaches. Methods Advanced searches using the PubMed/MEDLINE, Web of Science, Cochrane Library, Google Scholar, and ResearchGate databases were carried out for clinical studies by combining the terms "headache AND ecchymosis", "headache AND epistaxis", and "headache AND hematohidrosis" spanning all medical literature prior to October 10, 2015. Preferred Reporting Items for Systematic Reviews and Meta-analyses and Meta-analysis of Observational Studies in Epidemiology guidelines were applied. Results A total of 105 cases of SEHP associated with PHDs (83% migraine and 17% trigeminal autonomic cephalgias) were identified (median age 27 years, male to female ratio 1:2.3); 63% had epistaxis, 33% ecchymosis, and 4% hematohidrosis. Eighty-three percent of studies applied the International Classification of Headache Disorders diagnostic criteria. Eighty percent of the reported headaches were episodic and 20% were chronic. Twenty-four percent of studies reported recurrent episodes of SEHP. Conclusions Our results suggest that SEHP may be rare features of PHDs. Future studies would benefit from the systematic characterization of these phenomena.

Skin problems following septorhinoplasty.

OBJECTIVES/HYPOTHESIS: Septorhinoplasty is one of the most commonly performed plastic surgery procedures in the world. Studies on septorhinoplasty in the literature mainly focus on the surgical procedures and their outcomes, but the general appearance of the nose and nasal skin following surgery is also very important. STUDY DESIGN: Case-control study examining 30 septorhinoplasty patients and 20 septoplasty patients for postoperative skin conditions. RESULTS: There were significant differences identified between the septorhinoplasty group and the septoplasty group with respect to their mean preoperative Global Acne Grading System, Seborrheic Dermatitis Area Severity Index, and visual analog scores (acne, seborrhea, and ecchymosis). CONCLUSIONS: The aim of study was to identify and evaluate postoperative skin conditions among septorhinoplasty patients, as well as the progression and duration of treatment of these conditions. LEVEL OF EVIDENCE: 3b.
