Objective: The aim of the present study was to assess the safety and efficacy of Diclofenac sodium (DS) 140 mg medicated plaster vs. Diclofenac epolamine (DIEP) 180 mg medicated plaster and placebo plaster, for the treatment of painful disease due to traumatic events of the limbs., Patients and Methods: This was a multicenter, phase III study involving 214 patients, aged 18-65 years, affected by painful conditions due to soft tissue injuries. Patients were randomized to DS, DIEP or placebo arms and treated with once-daily application of the plaster for a total treatment period of 7 days. The primary objective was first to demonstrate the non-inferior efficacy of the DS treatment when compared to the reference DIEP treatment and second that both, test and reference treatments, were superior with respect to placebo. The secondary objectives included the evaluation of efficacy, adhesion, safety, and local tolerability of DS in comparison to both DIEP and placebo., Results: The mean visual analog scale (VAS) score decrease for pain at rest was higher in the DS (-17.65 mm) and the DIEP group (-17.5 mm) than in the placebo (-11.3 mm). Both active formulation plasters were associated with a statistically significant pain reduction compared to placebo. No statistically significant differences were observed between DIEP and DS plasters efficacy in relieving pain. Secondary endpoint evaluations supported the primary efficacy results. No serious adverse events (SAEs) were registered, and the most commonly detected adverse events were skin reactions at the application site., Conclusions: The results showed that both the DS 140 mg plaster and the reference DIEP 180 mg plaster are effective in relieving pain and present a good safety profile.

Background: Acid mist can suspend in the air and enter the body via skin contact, the respiratory tract, or even oral intake, which pose various health hazards. Previous studies have shown that occupational exposure to acid mist or acidic solutions is a major risk factor for oral diseases. However, the findings are inconsistent and do not consider individual factors and lifestyles that may cause the same oral diseases. Therefore, we conducted a comprehensive oral health survey and collected detail information to confirm the effect of acidic solution exposure on worker's oral health., Methods: From 4 acidic solution factories, a total of 309 subjects (157 in control and 152 in exposed group) was enrolled. All participants competed oral examinations and self-report questionnaire, including the decayed, missing, and filled teeth (DMFT) index, community periodontal index (CPI), loss of attachment (LA) index, and tooth erosion. Multivariate logistic regression analysis was used to determine the association between the acidic solution exposure and oral health., Results: The results showed that acid exposure was correlated with soft oral tissue injury rather than hard oral tissue in our survey. In the multivariate model (adjusted for sex, age, worked years, education level, mouthwash use, dental floss use, tooth brushing, mask use, smoking, drinking, chewing areca and dietary habits with acidic foods), significant relationships of acid exposure with LA score were observed (OR = 2.32, 95% CI 1.03-5.26). However, the presence of acid exposure was not significantly associated with tooth erosion, DMFT, and CPITN., Conclusion: Our study highlighted that occupational acid exposure was an independent risk factor for periodontal health, especially LA. It is important to strengthen occupational hazard control, educate workers on oral disease and related factors, and raise the awareness of oral hygiene.

A chemical alkali burn caused by ash and soot is quite rare, resulting from its high pH-value, and underestimated in its potential to cause injury. In folkloric medicine, ash was purportedly used to relieve pain. We present an unusual case of a 27-year-old man who used a self-mixed cream of soot of wooden pellets, milking grease and baby oil to blacken his face and hands for a traditional Krampus procession.

Aims: Studies have highlighted that antenatal steroids could have an effect on neonatal skin maturation. This study examined if there was a relationship between the administration of antenatal glucocorticoids for mothers and the skin injuries in their neonates. Data from skin injury audit were extracted from the neonatal database and analyzed to determine differences in the prevalence of neonates with pressure injuries [cases] whose mothers had received antenatal steroids, compared to those without pressure injuries [control]., Results: Of 247 neonates audited, 77 [31%], had documented pressure injuries, 170 [69%] had no documented injury. The median birth weight and gestation were 1400 g [IQR 893-2268 g] and 30.3 weeks [IQR 26.3-40.0 weeks] respectively. Of the neonates born less than 34 weeks, 80% were exposed to antenatal steroids and were equally distributed across patient genders. Within the 77 cases, 53 [66%] were exposed to antenatal steroids compared to controls in which 88 [53%] had not. The effect between cases and controls was not statistically significant [χ2 = 2.81, P = 0.09]. However a difference was noted between genders, as female neonates benefited from the exposure to steroids [OR = 0.317, 95% [CI 0.105-0.956], p value -0.041]., Conclusion: Antenatal glucocorticoids appear to be beneficial in reducing pressure injury prevalence in female neonates.

Adverse soft tissue reactions in patients with metal-on-metal (MoM) hip replacement are associated with cobalt (Co) and chromium (Cr) particles released from the implant. Exposing the patients to long periods of increased metal ions concentrations resulting from the wear of these implants poses an increased risk of genotoxicity/mutagenicity. A variable proportion of patients develop periprosthetic soft-tissue masses or pseudotumors at the site of the implant. There is a concern that exposure to increased metal ions could increase the risk of cancer. In order to investigate whether the periprosthetic soft-tissue mass harbours any cancer- related genetic alterations, we studied DNA isolated from periprosthetic tissues of 20 patients with MoM hip replacement, for copy number alterations and mutations in hotspot regions of 50 cancer genes using aCGH and amplicon-based next generation sequencing. Our results showed copy number gains at 12q14.3 and 21q21.1in tumour from patient diagnosed with liposarcoma. Copy number alterations in periprosthetic tissues were seen in three other patients, one had a region of gain at 9q24.1 affecting JAK2 and INSL6, and two patients had region of gain at 6p21.1, affecting RUNX2. Mutation analysis showed V1578del mutation in NOTCH1 in two patients. The copy number alterations and mutations seen in periprosthetic soft-tissue masses are earlier reported in either haematological malignancies or in osteoblast related bone dysplasia. The presence of genetic anomalies was associated with longer in-situ time of the implant. Our findings warrant the need of similar studies in larger patient cohorts to evaluate the risk of development of neoplastic alterations in periprosthetic tissues of patients with MoM hip replacement., (Copyright © 2015 Elsevier B.V.

Objectives: To compare smokers to non-smokers in terms of soft tissue alterations following single implant treatment in healed bone., Material and Methods: Non-smoking and smoking patients with sufficient bone volume in need of a single implant in the anterior maxilla (15-25) were consecutively recruited in three centres. Conventional single implant surgery was performed and an immediate provisional crown was installed. Eight to 12 weeks later, the latter was replaced by a permanent one (baseline). Papilla regrowth and midfacial recession was registered after 2 years of function., Results: The sample consisted of 39 non-smokers (21 females; mean age 42) and 46 smokers (22 females; mean age 45). Smokers had three early failures, whereas all implants integrated successfully in non-smokers. Statistically significant papilla regrowth was observed in non-smokers (distal 0.63 mm, mesial 0.76 mm), whereas smokers showed stable papillae (between cohorts: P ≤ 0.025). Midfacial soft tissue level demonstrated statistically significant regrowth in non-smokers (0.53 mm), whereas it remained stable in smokers (between cohorts: P = 0.004)., Conclusion: Smokers failed to demonstrate papilla regeneration and showed more midfacial recession following single implant treatment when compared to non-smokers., (© 2014 John Wiley & Sons A/S.

Prescription drug abuse ranks as the second most common class of illicit drug use in the United States, and one mechanism of opiate abuse involves intravenous injection of enteral narcotics such as oxycodone or hydrocodone. The authors describe a patient who sustained significant soft tissue necrosis after intravenously injecting a solution made from crushed enteral narcotics, with a focus on the operative course that resulted due to a delay in initial definitive treatment. The patient's wounds encompassed 8% total body surface area and covered 247 cm2. A 55-year-old female was admitted to the burn unit (West Penn Burn Center, Western Pennsylvania Hospital, Pittsburgh, PA) after she initially presented with infection and cellulitis to her bilateral upper extremities 3 weeks after intravenously injecting herself with crushed oxycodone/acetaminophen. She underwent numerous sequential operative repairs including initial debridement, placement of dermal replacement templates, and several split-thickness autografts and xenografts. Her total length of stay was 59 days, broken into an initial 47-day stay, and a subsequent 12-day readmission due to graft failure secondary to poor follow-up. As the number of prescription drug abusers rises, it is possible that an increase in attempts to intravenously abuse enteral narcotics may also rise. As such, burn centers should be prepared for the extent of potential limb necrosis and the operative treatment that may ensue.

Purpose: The aim of this study was to collect and describe all published reports of local tissue injury or extravasation from vasopressor administration via either peripheral intravenous (IV) or central venous catheter., Methods: A systematic search of Medline, Embase, and Cochrane databases was performed from inception through January 2014 for reports of adults who received vasopressor intravenously via peripheral IV or central venous catheter for a therapeutic purpose. We included primary studies or case reports of vasopressor administration that resulted in local tissue injury or extravasation of vasopressor solution., Results: Eighty-five articles with 270 patients met all inclusion criteria. A total of 325 separate local tissue injury and extravasation events were identified, with 318 events resulting from peripheral vasopressor administration and 7 events resulting from central administration. There were 204 local tissue injury events from peripheral administration of vasopressors, with an average duration of infusion of 55.9 hours (±68.1), median time of 24 hours, and range of 0.08 to 528 hours. In most of these events (174/204, 85.3%), the infusion site was located distal to the antecubital or popliteal fossae., Conclusions: Published data on tissue injury or extravasation from vasopressor administration via peripheral IVs are derived mainly from case reports. Further study is warranted to clarify the safety of vasopressor administration via peripheral IVs., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Pingyangmycin is a commonly used drug in China for the treatment of infantile hemangiomas (IHs) and vascular malformations. Also known as bleomycin A5, it has a similar chemical structure to bleomycin. The side effects of bleomycin include swelling, erythema, fever, headache, hyperpigmentation, ulceration, allergic reactions, and pulmonary fibrosis. We conducted this retrospective study to identify the correlation between bleomycin A5 injections and soft tissue atrophy. We performed a retrospective chart review of all patients with IHs who had this treatment and presented with soft tissue atrophy in our department from January 2011 through July 2013. Eighteen children with IHs (14 girls, 4 boys) were included in this study. The average age was 8.6 ± 3.8 years. All of the atrophied deformities were located at the injection site. Thirteen (72.2%) were located on the upper lip, three (16.7%) on the nose, and two (11.1%) on the cheeks. Seventeen (94.5%) received their first injection at the age of 1 or 2 months. The mean number of injections was 3.5 ± 1.6. The mean interval between injections was 1.2 ± 0.3 months. Eight of 18 patients (44.4%) had ulceration after injection. Intralesional bleomycin A5 injection is not safe for the treatment of IHs because it may lead to soft tissue atrophy. Other safer treatments, such as oral propranolol, should replace this treatment., (© 2015 Wiley Periodicals, Inc.)

Study Design: Basic science rodent model of bone morphogenetic protein-2 (BMP-2) soft-tissue inflammation., Objective: This study investigated the anti-inflammatory effect of human dose equivalent (HDE) dexamethasone (DM) for treatment of BMP-2-related soft-tissue inflammation in a rodent model and suggests an appropriate dose for utilization in the clinical practice of spine surgeons., Summary of Background Data: BMP-2 is frequently used in spinal surgery to augment fusion. Yet, side effects of soft-tissue inflammation have been observed. DM decreases proinflammatory cytokine production and cellular immune response. However, the anti-inflammatory effects of HDE DM in a rodent model of BMP-2-associated soft-tissue inflammation have not been reported., Methods: Five, 10, and 15 mg of HDE DM were administered 3 times perioperatively to rodent cohorts receiving BMP-2 paraspinal implants and compared against BMP-2 only positive controls and phosphate buffer negative controls (n = 6 subjects per group). Histopathology, magnetic resonance imaging, and gross dissection were used as measures of cellular, edematous, and exudative inflammatory response. Serial killings were made on day 2 and day 7 postoperatively., Results: Magnetic resonance imaging volume rendering demonstrated inflammatory edema decreased by 49% from 605.4 mm to 304.03 mm in subjects treated with 5, 10, or 15 mg of HDE DM (P < 0.05). Histopathological analysis demonstrated inflammatory cross-sectional area decreased 28.8% from 1.84 mm to 1.31 mm in subjects treated with 5, 10 or 15 mg of HDE DM (P < 0.05). Immune cellular infiltration depth decreased 38.5% from 0.26 mm to 0.16 in subjects treated with 15 mg of HDE DM (P < 0.05). Gross anatomical inflammatory exudates were prevented in 100% of subjects treated with 10 or 15 mg of HDE DM (P < 0.05)., Conclusion: Low-dose DM administration is effective in controlling the cellular inflammation and edema resulting from BMP-2. Ten or 15 mg of DM might be considered by spine surgeons for controlling the inflammation and edema seen in spine surgery with BMP-2.

Skeletal muscle regeneration following injury is accompanied by rapid infiltration of macrophages, which play a positive role in muscle repair. Increased chronic inflammation inhibits the regeneration of dystrophic muscle, but the properties of inflammatory cells are not well understood in the context of normal muscle aging. This work uncovers pronounced age-specific changes in the expression of osteopontin (OPN) in CD11b+ macrophages present in the injured old muscle as well as in the blood serum of old injured mice and in the basement membrane surrounding old injured muscle fibers. Furthermore, young CD11b+ macrophages enhance regenerative capacity of old muscle stem cells even when old myofibers and old sera are present; and neutralization of OPN similarly rejuvenates the myogenic responses of old satellite cells in vitro and notably, in vivo. This study highlights potential mechanisms by which age related inflammatory responses become counter-productive for muscle regeneration and suggests new strategies for enhancing muscle repair in the old.

Once initiated, how tissue injury expands after high toxicant doses, even after their complete elimination, is not understood. Free-radical generation was initially proposed to mediate progression of injury. However, mechanisms proposed thus far have remained unsubstantiated. Necrotic injury is characterized by loss of osmoregulation, cell swelling, blebbing, and cell rupture. This exposes cytosolic enzymes, including proteases, phospholipases, and lysosomal Ca(2+)-dependent enzymes, to high extracellular calcium (Ca(2+)). Activated hydrolytic enzymes, termed 'death proteins,' hydrolyze their substrates in the plasma membrane of neighboring cells, commencing self-perpetuated injury progression. Likewise, ischemia-reperfusion injury exposes the hydrolytic enzymes to high Ca(2+), fuelling the progression of tissue injury. This mechanism is independent of the offending toxicant that initiates the injury. I present here a case for therapeutic intervention with inhibitors directed against death proteins as a means to avert organ failure and death well after the poisoning event., (Copyright © 2012.

This represents the largest case of skin necrosis related to levamisole, a common cocaine contaminant, requiring closure with skin grafts, and is the only case resulting in nasal amputation, central upper lip excision, extremity bone necrosis, and above knee amputation. The case report is followed by a review of the literature. Unique considerations for the full-thickness necrosis induced by levamisole vasculitis are highlighted, including antibody level monitoring, need for multiple excisions, timing of skin grafting, and potential for soft tissue and bone necrosis as well. A 54-year-old man presented to an outside facility with fever, generalized weakness, and agranulocytosis, with a history of cocaine use 3 weeks before. After admission, he developed generalized violaceous lesions and an elevated p-antineutrophilic cytoplasmic antibody and was diagnosed with disseminated vasculitis and agranulocytosis secondary to levamisole-contaminated cocaine exposure. On transfer to the authors' facility, 52% TBSA was involved with violaceous, nonblanching lesions, which progressed to full-thickness necrosis. Local wound care continued until necrotic areas fully demarcated and progressive necrosis stabilized, and skin grafting for closure was not performed until antibody levels normalized. Current treatment of levamisole-induced skin rash or necrosis focuses on discontinuation of levamisole. As demonstrated by this case, extensive necrosis secondary to levamisole-induced vasculitis can be successfully treated with multiple excisions until necrosis stabilizes, and then, split-thickness autografts may be applied. In areas with poor vascular supply or areas with poor functional prognosis, amputation may ultimately be required.

Free flap reconstruction in infants is extremely rare. A seven-and-a-half-month-old male infant sustained an extensive soft tissue defect on his left knee caused by extravasation of an intraosseous arterenol infusion. A free latissimus dorsi flap was successfully performed for soft tissue reconstruction. Indications, advantages, and outcome of the procedure are discussed., (Copyright © 2011 Elsevier Inc.

Systemic treatment with chemotherapeutic agents is often applied by infusions over peripheral vein cannulae located on the hands and lower arms. Dislocation of the cannulae or vein perforation causes an extravasation of the cytostatic agent. This complication occurs in approximately 0.1 - 6 % of intravenous treatments and is rarely noticed before administration of greater volumes. Depending on the tissue toxicity of the administered substances, the extravasation results in tissue damage of different extents. In a few cases, only conservative therapy is required. The majority of patients, however, needs immediate surgical therapy. The reason for this is the severe tissue damage caused by the chemotherapeutic agent that accumulates in the subcutaneous fat where it destroys the connective and fat tissue, nerves, vessels, tendons and muscles, impairing the functionality of the entire hand and arm. In very severe cases, partial or complete amputation of the extremity is the only treatment. The application of antidotes has been discussed controversially and is not a standard procedure. In the past 11 years, 18 patients with extravasations of chemotherapeutics on the dorsum of the hand were admitted to our department. After radical debridement no primary closure of the resulting defect was advisable in the first operation. In all cases we could later perform a stable wound closure. In our opinion, this two-step procedure with primary radical debridement, temporary wound coverage and later wound closure should be performed regularly.

Palifermin (deltaN23KGF) decreases the incidence, severity, and duration of oral mucositis. The objectives of this open-label study were to evaluate the pharmacokinetics of single-dose palifermin in subjects with varying degrees of renal function. A single 90-mcg/kg intravenous dose of palifermin was administered to 31 subjects with varying levels of renal function (normal to requiring hemodialysis). Pharmacokinetic analyses were conducted using serum palifermin concentrations. There was considerable overlap in mean palifermin serum clearance among the groups, ranging from 318 to 495 mL/h/kg, indicating that the level of renal function did not affect clearance in humans; thus, no dose adjustment of palifermin is indicated for patients with renal dysfunction.

Most chemotherapeutic agents can cause varying degrees of local tissue injuries when extravasated. The medical treatment of extravasation is based on proper maintenance of the intravenous (IV) line and application of cold or warm compresses, plus the use of antidotes when available. Antidotes for extravasation that have been shown to be useful are sodium thiosulfate for nitrogen mustard, dimethylsulfoxide for anthracyclines and mitomycin, and hyaluronidase for the vinca alkaloids. New treatments include dexrazoxane, sargramostim, and hyperbaric oxygen for doxorubicin extravasations. Tissue damage secondary to drug infiltration occurs as a result of one of two major mechanisms: (1) the drug is absorbed by local cells in the tissue and binds to critical structures (eg, DNA, microtubules), causing cell death; and (2) the drug does not bind to cellular DNA. Damage to immediately adjacent tissue is more readily neutralized than is damage to surrounding tissue.

Systemic intravenous chemotherapeutic agents can cause multiple emergency situations including acute and chronic local and systemic reactions. Amongst them, drug extravasation is one of the most devastating complications, as many drugs can cause varying degrees of local tissue injury when extravasated. Although it is difficult to give an accurate measurement, the incidence of extravasation of systemic infusional chemotherapeutic agents has been reported to occur in 0.1-6.5% of cases. Since most extravasations can be prevented with the systematic implementation of careful administration techniques, guidelines have been published for the administration of vesicant drugs. The proper maintenance of intravenous lines, application of local cooling or warming for certain extravasations, and the use of antidotes to prevent the local toxic action of the extravasated drugs are the basis of medical management. The specific antidotes for certain chemotherapeutic agents are also discussed in this article.

Tissue damage due to direct contact of liquid propane with the integument is extremely rare. Only five such cases have been described in the literature. We report the case of a girl who sustained a full-thickness skin necrosis of 14.5 % of her body surface area. There is little agreement about the optimal treatment of these injuries in previous reports. The pathophysiological mechanism suggests a freezing injury. The treatment, however, should be analogous to that of third-degree burns.

A 40-year-old man with a history of schizophrenia and inflammatory soft tissue lesions after self-injection of elemental mercury presented to the Emergency Department. Multiple skin abscesses associated with fever required operative debridement. An incidental finding of oral mercury ingestion was followed clinically and did not result in complications. Exposure to elemental mercury through injection or ingestion is an uncommon event, but one the Emergency Physician may encounter. Subcutaneous mercury injection should be managed with local wound debridement, whereas ingestions are rarely of clinical significance.

Purpose: The purpose of this study was to determine whether dopamine-induced tissue extravasation injury could be prevented with phentolamine., Materials and Methods: This was a prospective, randomized, blinded, and controlled animal study. Forty rats were evaluated to document the effects of dopamine compared with normal saline on tissue integrity, whether any tissue damage was concentration or volume dependent, and to determine the minimum concentration of dopamine resulting in tissue injury. Dopamine concentrations of 0.8 mg/mL and 3.2 mg/mL were tested. In a second part of this study, an additional 40 rats were evaluated to assess the efficacy of two different doses of phentolamine (0.5 mg and 1 mg) or normal saline, when injected within 10 minutes of dopamine administration to prevent or reverse tissue extravasation. Extravasation sites were evaluated clinically and histologically at 2, 4, 6, and 8 hours and were compared with a baseline sample. Outcome measures were as follows: (1) prebiopsy was ectodermal erythema, induration, and blanching; (2) postbiopsy was bubbling, darkening, pallor, and hematoma of the muscle fascia. Histology included neutrophil migration, mast cell degranulation, edema, and hemorrhage. Fisher's Exact Test with the Bonferroni method were used for statistical analysis., Results: Dopamine-induced extravasation resulted in tissue injury characterized by blanching and hematoma. Damage did not appear to be volume dependent, but may be related to the duration of infiltration. Subcutaneous injection with either dose of phentolamine appeared to be clinically effective in preventing tissue injury. However, microscopic evaluation of tissue samples was inconclusive., Conclusion: This study clinically supported the use of phentolamine for the prevention of dopamine-induced extravasation injury.

Five clinically healthy Thoroughbred geldings were injected with Freund's adjuvant 3 times to induce a chronic inflammatory response. Blood was collected at various times before and after adjuvant administration. Clinical responses (rectal temperature and general demeanor) were also monitored. Adjuvant injection induced increases in rectal temperature and plasma fibrinogen concentration (maximum levels measured were mean +/- s.d. 39.7 +/- 0.5 degrees C and 8.2 +/- 0.3 g/l, respectively), indicative of an inflammatory response. A mild clinical depression was also observed in the horses for 24 h after the first injection of adjuvant only. Plasma cortisol levels decreased significantly from control levels of mean +/- s.d. 187.7 +/- 24.3 nmol/l to a minimum of 80.2 +/- 22.1 nmol/l (P < 0.01) 9 days after the first injection of adjuvant. Conversely, plasma insulin levels increased after the first injection of adjuvant to a maximum (96.7 +/- 15.2 iu/ml; P < 0.01) 12 days later, while plasma glucose concentrations tended to decline. A control group of horses to rule out contemporary environmental influences on the physiological and biochemical indices measured was not included in this study. The results show that chronic inflammation in the horse depressed resting plasma cortisol concentrations.

Background: Paclitaxel is a diterpenic plant product that has significant activity in several solid tumors, including epithelial ovarian cancer. After promising results in Phase I and II studies, its use has increased dramatically. With this increased use, isolated reports of local tissue reactions to paclitaxel have been described. The purpose of this study was to characterize further the presentation and clinical course of this toxic effect., Methods: Nine hundred fifty-five courses of paclitaxel were administered to patients with gynecologic malignancies at M. D. Anderson Cancer Center during a 13-month period. Nineteen (2%) local infusion-site injuries in 17 patients were observed., Results: The primary disease site was the ovary in 13 patients, the peritoneum in 2, and the endometrium in 2. Paclitaxel was administered as initial therapy in 6 patients and as salvage therapy in 11. Clinical evidence of infiltration was documented during infusion in 8 of 19 (42%) reported episodes. Immediate reactions consisting of mild discomfort, erythema, and edema were observed in six patients, three of whom had complete resolution of the lesion within 1 month. The remaining patients noted initial development of injury between 3 and 13 days after paclitaxel infusion. The typical injury was a discolored, raised, rounded, and indurated lesion that was moderately painful. Two patients (11%) had Grade 1 lesions, 13 (68%) had Grade 2 lesions, and four (21%) had Grade 3 lesions with central ulceration. Cellulitis requiring intravenous antibiotic therapy was associated with two lesions. At last follow-up, 13 injuries had persistent discoloration and induration; one patient had persistent ulceration present at the time of her death 6 months after presentation and one patient underwent excision of a persistent lesion at 12 months., Conclusions: Given the incidence of Grade 2 and Grade 3 local reactions, it appears that paclitaxel should be considered a vesicant.

Inadvertent extravasation during intravenous antitumor therapy is not an unusual complication and can cause damage ranging from minor erythema to severe local necrosis. The appropriate management of these iatrogenic accidents as a part of supportive care in oncology has been addressed by several experimental studies, but there has been little clinical study and no conclusive evidence on the best therapeutic strategies to adopt. The case reported here of a patient suffering from severe soft-tissue injury caused by extravasation of epidoxorubicin demonstrates the usefulness of a combined management (medical, surgical and rehabilitative) in the appropriate care of extravasation.

A term baby with neonatal convulsions secondary to birth asphyxia was given i.v. phenytoin via a cannula in the dorsum of the hand at 17 h of age. She developed a blue discolouration in the tissues surrounding the i.v. site. The infusion was aborted but the discolouration gradually spread to the rest of the hand. Twenty hours later, improvement could be detected although a blister appeared near the i.v. site. A further attempt two days later to administer phenytoin via an i.v. cannula sited in the left foot was aborted after the appearance of a similar reaction.
