RESUMO

Mineral oils and waxes are mixtures of predominantly saturated hydrocarbons consisting of straight-chain, branched and ring structures with carbon chain lengths greater than C14. They have been used for many decades in skin and lip care cosmetic products due to their excellent skin tolerance as well as their high protecting and cleansing performance and broad viscosity options. In contrast to vegetable oils, mineral oils are non-allergenic since they are highly stable and not susceptible to oxidation or rancidity. They have a long history of safe use which is confirmed by clinical and epidemiological data. In Europe, mineral oils are only permitted in cosmetics if compliant with purity specifications on polycyclic aromatic hydrocarbons and safety requirements laid down in the European pharmacopoeia and the EU cosmetics regulation EC/1223/2009. The high quality of these mineral oils is assured by robust quality assurance and a refining/purification process designed to exclude substances with carcinogenic potential and to minimize the presence of mineral oil aromatic hydrocarbons. Given their highly lipophilic properties, mineral oils do not penetrate human skin and, thus, are not systemically bioavailable in the body. Moreover, no significant changes in the skin and no effects on any internal organ system have been reported and attributed to the topical application of refined mineral oils. Regarding potential oral exposure from cosmetic lip care products, Cosmetics Europe, the European trade association for the cosmetics and personal care industry, has advised cosmetic manufacturers to only use mineral oil fractions for which recognized food acceptable daily intake (ADI) values apply. The estimated dose of mineral oils ingested via lip care products contributes to <10% of the ADI value and should therefore be considered of no toxicological concern.

RESUMO

Exogenous lipoid pneumonia is a rare alveolar-filling disorder characterized by foreign body reaction to inhaled/aspirated hydrocarbon that may be vegetable oil, animal fat, or mineral oil. It is vanishingly rare and often missed except in the classical clinical settings of acute aspiration of petroleum products. We present a toddler with iatrogenic exogenous lipoid pneumonia and highlight clinical and radiological clues that can prompt early recognition of this entity.

RESUMO

BACKGROUND: To improve the penile contour, some men choose to undergo implantation or injection of nonbiological materials. Foreign body reactions in penile tissue may produce scarring, deformity, ulceration, necrosis, and even gangrene. Consensus is lacking regarding the most effective surgical procedure for reconstruction of these penile lesions. OBJECTIVES: The authors describe one case study and the first systematic review focusing on reconstructive surgical management for penile lesions secondary to foreign body reaction. METHODS: PubMed, Medline, and Cochrane databases were queried for publications written in English, French, Portuguese, and Spanish from 1951 to May 2017. Multiple search terms were applied. RESULTS: Of the 3304 articles identified, 51 were included in the systematic review. All were retrospective studies, case series, or case reports. A total of 260 patients underwent surgical procedures, and the complication rate was 37.3%. The scrotal flap technique was performed most frequently (43.4%) and resulted in 65.6% of the total complications observed. One Brazilian case study was also described with an extensive and circumferential ulcer after six mineral oil bolls implant in the penile subcutaneous tissue. CONCLUSIONS: Restoration of the penile shape preserving the functionality and maintaining a good physician-patient relationship may be a challenge. The scrotal pouch may be advantageous for patch grafting of penile soft-tissue lesions, owing to its skin laxity and good blood supply. A less aggressive surgical approach has the benefits of shorter healing time and fewer early complications. Penile injuries are best treated by experienced surgeons on a case-by-case basis with care given to identify the most appropriate treatment.

RESUMO

Foreign modelling agent reactions (FMAR) are the result of the injection of unapproved high-viscosity fluids with the purpose of cosmetic body modelling. Its consequences lead to ulceration, disfigurement and even death, and it has reached epidemic proportions in several regions of the world. We describe a series of patients treated for FMARs in a specialised wound care centre and a thorough review of the literature. A retrospective chart review was performed from January 1999 to September 2015 of patients who had been injected with non-medical foreign agents and who developed cutaneous ulceration needing treatment at the dermatology wound care centre. This study involved 23 patients whose ages ranged from 22 to 67 years with higher proportion of women and homosexual men. The most commonly injected sites were the buttocks (38·5%), legs (18%), thighs (15·4%) and breasts (11·8%). Mineral oil (39%) and other unknown substances (30·4%) were the most commonly injected. The latency period ranged from 1 week to 17 years. Complications included several skin changes such as sclerosis and ulceration as well as systemic complications. FMAR is a severe syndrome that may lead to deadly complications, and is still very common in Latin America.

RESUMO

Objective: To study the etiological, clinical, radiological, diagnostic, therapeutic, and prognostic manifestations of exogenous lipoid pneumonia (ELP), and therefore to improve the diagnosis and treatment of this disease. Methods: The clinical data of 12 cases of ELP confirmed by pathology were retrospectively analyzed. Results: The patients consisted of 9 males and 3 females, with an average age of 73.8 years (range, 44 to 100 years). The underlying diseases were variable, including diseases affecting the general condition (multiple organ failure, chronic heart and renal insufficiency, pemphigoid, etc) and conditions with increased risk of aspiration (sequelae of cerebrovascular disease, Alzheimer's disease, advanced stage of nasopharyngeal carcinoma, paralytic ileus, etc). The 12 cases were all caused by Inhalation of mineral oil. Common symptoms included cough, sputum production and dyspnea. ELP had no special physical signs. Inflammation indexes, such as white blood cell, neutrophil percentage, ESR, C reactive protein, procalcitonin, D-Dimer, and blood lipid levels were usually normal. Radiological features of ELP mainly included consolidation, mass or nodules, with a little ground-glass opacity. Some patients had ventilation and/or diffusion dysfunction. The diagnostic methods included CT-guided percutaneous lung biopsy, thoracoscopy, thoracotomy or autopsy. Histopathological findings showed accumulation of large foamy macrophages in the alveolar spaces, with a few lipid deposition and polykaryocytes. The main treatment of ELP was cessation of lipid material contact. One case died of ELP, 6 died of other coexisting diseases, and the rest 6 improved with treatment and were discharged. The survival patients were all stable during a follow-up of 2-4.5 years. Conclusions: ELP was rare and its clinical manifestation was atypical. Its radiological manifestations were indistinguishable from pneumonia, lung cancer, interstitial lung diseases, etc. Pathological examination was the gold standard for diagnosis, and the preferred means of sampling was bronchoscopy. In cases whose diagnosis could not be confirmed by BALF, CT-guided percutaneous lung biopsy might be considered. The most important treatment is cessation of lipid material contact. The prognosis is good.

RESUMO

BACKGROUND: Constipation within childhood is an extremely common problem. Despite the widespread use of osmotic and stimulant laxatives by health professionals to manage constipation in children, there has been a long standing paucity of high quality evidence to support this practice. OBJECTIVES: We set out to evaluate the efficacy and safety of osmotic and stimulant laxatives used to treat functional childhood constipation. SEARCH METHODS: We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, and the Cochrane IBD Group Specialized Trials Register from inception to 10 March 2016. There were no language restrictions. We also searched the references of all included studies, personal contacts and drug companies to identify studies. SELECTION CRITERIA: Randomised controlled trials (RCTs) which compared osmotic or stimulant laxatives to placebo or another intervention, with participants aged 0 to 18 years old were considered for inclusion. The primary outcome was frequency of defecation. Secondary endpoints included faecal incontinence, disimpaction, need for additional therapies and adverse events. DATA COLLECTION AND ANALYSIS: Relevant papers were identified and two authors independently assessed the eligibility of trials, extracted data and assessed methodological quality using the Cochrane risk of bias tool. The primary outcome was frequency of defecation. Secondary endpoints included faecal incontinence, disimpaction, need for additional therapies and adverse events. For continuous outcomes we calculated the mean difference (MD) and 95% confidence interval (CI) using a fixed-effect model. For dichotomous outcomes we calculated the risk ratio (RR) and 95% CI using a fixed-effect model. The Chi(2) and I(2) statistics were used to assess statistical heterogeneity. A random-effects model was used in situations of unexplained heterogeneity. We assessed the overall quality of the evidence supporting the primary and secondary outcomes using the GRADE criteria. MAIN RESULTS: Twenty-five RCTs (2310 participants) were included in the review. Fourteen studies were judged to be at high risk of bias due to lack of blinding, incomplete outcome data and selective reporting. Meta-analysis of two studies (101 patients) comparing polyethylene glycol (PEG) with placebo showed a significantly increased number of stools per week with PEG (MD 2.61 stools per week, 95% CI 1.15 to 4.08). Common adverse events in the placebo-controlled studies included flatulence, abdominal pain, nausea, diarrhoea and headache. Participants receiving high dose PEG (0.7 g/kg) had significantly more stools per week than low dose PEG (0.3 g/kg) participants (1 study, 90 participants, MD 1.30, 95% 0.76 to 1.84). Meta-analysis of 6 studies with 465 participants comparing PEG with lactulose showed a significantly greater number of stools per week with PEG (MD 0.70 , 95% CI 0.10 to 1.31), although follow-up was short. Patients who received PEG were significantly less likely to require additional laxative therapies. Eighteen per cent (27/154) of PEG patients required additional therapies compared to 31% (47/150) of lactulose patients (RR 0.55, 95% CI 0.36 to 0.83). No serious adverse events were reported with either agent. Common adverse events in these studies included diarrhoea, abdominal pain, nausea, vomiting and pruritis ani. Meta-analysis of 3 studies with 211 participants comparing PEG with milk of magnesia showed that the stools per week were significantly greater with PEG (MD 0.69, 95% CI 0.48 to 0.89). However, the magnitude of this difference was quite small and may not be clinically significant. One child was noted to be allergic to PEG, but there were no other serious adverse events reported. One study found a significant difference in stools per week favouring milk of magnesia over lactulose (MD -1.51, 95% CI -2.63 to -0.39, 50 patients), Meta-analysis of 2 studies with 287 patients comparing liquid paraffin (mineral oil) with lactulose revealed a relatively large statistically significant difference in the number of stools per week favouring liquid paraffin (MD 4.94 , 95% CI 4.28 to 5.61). No serious adverse events were reported. Adverse events included abdominal pain, distention and watery stools. No statistically significant differences in the number of stools per week were found between PEG and enemas (1 study, 90 patients, MD 1.00, 95% CI -1.58 to 3.58), dietary fibre mix and lactulose (1 study, 125 patients, P = 0.481), senna and lactulose (1 study, 21 patients, P > 0.05), lactitol and lactulose (1 study, 51 patients, MD -0.80, 95% CI -2.63 to 1.03), hydrolyzed guar gum and lactulose (1 study, 61 patients, MD 1.00, 95% CI -1.80 to 3.80), PEG and flixweed (1 study, 109 patients, MD 0.00, 95% CI -0.33 to 0.33), PEG and dietary fibre (1 study, 83 patients, MD 0.20, 95% CI -0.64 to 1.04), and PEG and liquid paraffin (2 studies, 261 patients, MD 0.35, 95% CI -0.24 to 0.95). AUTHORS' CONCLUSIONS: The pooled analyses suggest that PEG preparations may be superior to placebo, lactulose and milk of magnesia for childhood constipation. GRADE analyses indicated that the overall quality of the evidence for the primary outcome (number of stools per week) was low or very low due to sparse data, inconsistency (heterogeneity), and high risk of bias in the studies in the pooled analyses. Thus, the results of the pooled analyses should be interpreted with caution because of quality and methodological concerns, as well as clinical heterogeneity, and short follow-up. There is also evidence suggesting the efficacy of liquid paraffin (mineral oil). There is no evidence to demonstrate the superiority of lactulose when compared to the other agents studied, although there is a lack of placebo controlled studies. Further research is needed to investigate the long term use of PEG for childhood constipation, as well as the role of liquid paraffin. The optimal dose of PEG also warrants further investigation.

RESUMO

Unless stimulated by a chronic inflammatory agent, such as mineral oil, plasma cell tumors are rare in young BALB/c mice. This raises the questions: What do inflammatory tissues provide to promote mutagenesis? And what is the nature of mutagenesis? We determined that mineral oil-induced plasmacytomas produce large amounts of endogenous retroelements--ecotropic and polytropic murine leukemia virus and intracisternal A particles. Therefore, plasmacytoma formation might occur, in part, by de novo insertion of these retroelements, induced or helped by the inflammation. We recovered up to ten de novo insertions in a single plasmacytoma, mostly in genes with common retroviral integration sites. Additional integrations accompany tumor evolution from a solid tumor through several generations in cell culture. The high frequency of de novo integrations into cancer genes suggests that endogenous retroelements are coresponsible for plasmacytoma formation and progression in BALB/c mice.

RESUMO

Lipoid pneumonia (LP) is a chronic inflammation of the lung parenchyma with interstitial involvement due to the accumulation of endogenous or exogenous lipids. Exogenous LP (ELP) is associated with the aspiration or inhalation of oil present in food, oil-based medications or radiographic contrast media. The clinical manifestations of LP range from asymptomatic cases to severe pulmonary involvement, with respiratory failure and death, according to the quantity and duration of the aspiration. The diagnosis of exogenous lipoid pneumonia is based on a history of exposure to oil and the presence of lipid-laden macrophages on sputum or bronchoalveolar lavage (BAL) analysis. High-resolution computed tomography (HRCT) is the imaging technique of choice for evaluation of patients with suspected LP. The best therapeutic strategy is to remove the oil as early as possible through bronchoscopy with multiple BALs and interruption in the use of mineral oil. Steroid therapy remains controversial, and should be reserved for severe cases. We describe a case of LP due to oil aspiration in 3-year-old girl with intractable epilepsy on ketogenic diet. Diagnostic problems were due to non-specific symptoms that were mimicking serious infectious pneumonia. A high index of suspicion and precise medical history is required in cases of refractory pneumonia and fever unresponsive to conventional therapy. Gastroesophageal reflux and a risk of aspiration may be regarded as relative contraindications to the ketogenic diet. Conservative treatment, based on the use of oral steroids, proved to be an efficient therapeutic approach in this case.

RESUMO

Hypercalcemia is a frequent condition in clinical practice and when the most frequent causes are excluded, etiological diagnosis can be challenging. A rare cause of PTH-independent hypercalcemia is described in the present case report. A male adult with a history of androgenic-anabolic steroids abuse, and injection of mineral oil and oily veterinary compound containing vitamins A, D and E into muscles for local hypertrophy presented with hypercalcemia, nephrocalcinosis, and end-stage renal disease. On physical examination, the presence of calcified subcutaneous nodules and calcification of musculature previously infused with oily substances drew attention. Laboratory tests confirmed hypercalcemia of 12.62 mg/L, low levels of PTH (10 pg/mL), hyperphosphatemia (6.0 mg/dL), 25(OH)D of 23.3 ng/mL, and elevated 1,25(OH)2D (138 pg/mL). Imaging exams showed diffuse calcification of muscle tissue, subcutaneous tissue, and organs such as the heart, lung, and kidneys. The patient was diagnosed with PTH-independent hypercalcemia secondary to foreign body reaction in areas of oil injection. The patient underwent treatment with hydrocortisone for 10 days, single dose zoledronic acid and hemodialysis. He evolved with serum calcium levels of 10.4 mg/dL and phosphorus of 7.1 mg/dL. In addition, sertraline and quetiapine were prescribed to control body dysmorphic disorder. The medical community should become aware of new causes of hypercalcemia as secondary to oil injection since this should become increasingly frequent due to the regularity with which such procedures have been performed.

BACKGROUND: Constipation within childhood is an extremely common problem. Despite the widespread use of osmotic and stimulant laxatives by health professionals to manage constipation in children, there has been a long standing paucity of high quality evidence to support this practice. OBJECTIVES: We set out to evaluate the efficacy and safety of osmotic and stimulant laxatives used to treat functional childhood constipation. SEARCH METHODS: The search (inception to May 7, 2012) was standardised and not limited by language and included electronic searching (MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Inflammatory Bowel Disease and Functional Bowel Disorders Group Specialized Trials Register), reference searching of all included studies, personal contacts and drug companies. SELECTION CRITERIA: Randomised controlled trials (RCTs) which compared osmotic or stimulant laxatives with either placebo or another intervention, with patients aged 0 to 18 years old were considered for inclusion. The primary outcome was frequency of defecation. Secondary endpoints included faecal incontinence, disimpaction, need for additional therapies and adverse events. DATA COLLECTION AND ANALYSIS: Relevant papers were identified and the authors independently assessed the eligibility of trials. Methodological quality was assessed using the Cochrane risk of bias tool.The Cochrane RevMan software was used for analyses. Patients with final missing outcomes were assumed to have relapsed. For continuous outcomes we calculated a mean difference (MD) and 95% confidence interval (CI) using a fixed-effect model. For dichotomous outcomes we calculated an odds ratio (OR) and 95% confidence intervals (95% CI) using a fixed-effect model. The chi square and I(2) statistics were used to assess statistical heterogeneity. A random-effects model was used in situations of unexplained heterogeneity MAIN RESULTS: Eighteen RCTs (1643 patients) were included in the review. Nine studies were judged to be at high risk of bias due to lack of blinding, incomplete outcome data and selective reporting. Meta-analysis of two studies (101 patients) comparing polyethylene glycol (PEG) with placebo showed a significantly increased number of stools per week with PEG (MD 2.61 stools per week, 95% CI 1.15 to 4.08). Common adverse events in the placebo-controlled studies included flatulence, abdominal pain, nausea, diarrhoea and headache. Meta-analysis of 4 studies with 338 participants comparing PEG with lactulose showed significantly greater stools per week with PEG (MD 0.95 stools per week, 95% CI 0.46 to 1.44), although follow up was short. Patients who received PEG were significantly less likely to require additional laxative therapies. Eighteen per cent of PEG patients required additional therapies compared to 30% of lactulose patients (OR 0.49, 95% CI 0.27 to 0.89). No serious adverse events were reported with either agent. Common adverse events in these studies included diarrhoea, abdominal pain, nausea, vomiting and pruritis ani. Meta-analysis of 3 studies with 211 participants comparing PEG with milk of magnesia showed that the stools/wk was significantly greater with PEG (MD 0.69 stools per week, 95% CI 0.48 to 0.89). However, the magnitude of this difference is quite small and may not be clinically significant. One child was noted to be allergic to PEG, but there were no other serious adverse events reported. Meta-analysis of 2 studies with 287 patients comparing liquid paraffin (mineral oil) with lactulose revealed a relatively large statistically significant difference in the number of stools per week favouring paraffin (MD 4.94 stools per week, 95% CI 4.28 to 5.61). No serious adverse events were reported. Adverse events included abdominal pain, distention and watery stools. No statistically significant differences in the number of stools per week were found between PEG and enemas (1 study, 90 patients, MD 1.00, 95% CI -1.58 to 3.58), dietary fibre mix and lactulose (1 study, 125 patients, P = 0.481), senna and lactulose (1 study, 21 patients, P > 0.05), lactitol and lactulose (1 study, 51 patients, MD -0.80, 95% CI -2.63 to 1.03), and PEG and liquid paraffin (1 study, 158 patients, MD 0.70, 95% CI -0.38 to 1.78). AUTHORS' CONCLUSIONS: The pooled analyses suggest that PEG preparations may be superior to placebo, lactulose and milk of magnesia for childhood constipation. GRADE analyses indicated that the overall quality of the evidence for the primary outcome (number of stools per week) was low or very low due to sparse data, inconsistency (heterogeneity), and high risk of bias in the studies in the pooled analyses. Thus, the results of the pooled analyses should be interpreted with caution because of quality and methodological concerns, as well as clinical heterogeneity, and short follow up. However, PEG appears safe and well tolerated. There is also evidence suggesting the efficacy of liquid paraffin (mineral oil), which was also well tolerated.There is no evidence to demonstrate the superiority of lactulose when compared to the other agents studied, although there is a lack of placebo controlled studies. Further research is needed to investigate the long term use of PEG for childhood constipation, as well as the role of liquid paraffin.

RESUMO

OBJECTIVE: To report a rare case of penile paraffinoma caused by the subcutaneous or intra-urethral injection of foreign substances containing long-chain saturated hydrocarbons. These were injected in order to increase the penis size which generated a chronic granulomatous inflammatory reaction. This is a rare practice in the western world. METHODS: We present the case of a 32-year-old Bulgarian male who presented with a two-year history of elastic, slightly painful penis swelling after subcutaneous liquid paraffin injection. The proposed treatment was excision of the affected tissue and penile reconstruction in a two-stage procedure. RESULTS: The operative procedure was successful and the patient had good aesthetic and functional results. Paraffin and other materials injected into the penis can produce many complications. Foreign body granuloma, skin necrosis, penile deformity, chronic and unhealed ulcer, painful erection, and the inability to achieve a satisfactory sexual relationship are some of the resulting complications. Intralesional or systemic steroids have been used in primary sclerosing lipogranuloma resulting in the disappearance of the granuloma, but in our opinion the treatment of choice should be radical excision, and, if necessary, secondary reconstruction of the penis. CONCLUSION: The injection of foreign substances to enhance penis size is currently an unjustifiable practice. However, it is still carried out, especially in Eastern Europe and Asia. In most cases surgical treatment is needed to treat the complications and the best modality seems to be radical excision together with follow-up.

PURPOSE: The current study was directed to investigate the effectiveness of docosahexaenoic acid (DHA) as a chemopreventive agent on experimentally induced hamster buccal pouch (HBP) carcinogenesis. MATERIAL AND METHODS: In this study we used 40 Syrian male hamsters, five weeks old, were divided into 4 groups (GI, GII, GIII, and GIV) of 10 animals in each as follows, GI: Topical application of liquid paraffin alone (thrice a week for 14 weeks), GII: Topical application of 7, 12 dimethyl benz[a]anthracene (DMBA) alone (0.5% in liquid paraffin, thrice a week for 14 weeks), GIII: Topical application of DMBA (0.5% in liquid paraffin, thrice a week for 14 weeks) + Oral administration of DHA (125 mg/kg b.w. in 1 ml distilled water by oral gavage, thrice a week for 14 weeks on alternative days of DMBA application), GIV: Oral administration of DHA alone (125 mg/kg b.w. in 1 ml distilled water by oral gavage, thrice a week for 14 weeks). RESULTS: Gross observations and histopathological findings revealed that, in GI: normal stratified squamous epithelium, in GII: well and moderately differentiated squamous cell carcinoma (SCC), in GIII: variable results ranges from hyperkeratosis, hyperkeratosis and focal hyperplasia, mild dysplasia, and well differentiated SCC with superficial invasion of tumor cells not extended to deeper areas, while in GIV: normal similar to GI. Immunohistochemical results indicated that oral DHA treatment to DMBA treated hamsters restored the normal expression of bcl-2. CONCLUSION: Our results indicated that DHA has the potential to be a dietary chemopreventive agent due to its capacity to improve carcinogen detoxification and to block/suppress the initiation and promotion stages of experimentally produced HBP carcinogenesis.

RESUMO

INTRODUCTION: Subcutaneous penile injection of various oils for penile augmentation has been described among men in Laos. We have now treated three Laotian immigrants with penile disfigurement secondary to sclerosing lipogranulomas, also known as paraffinoma, induced by injection of a mineral oil compound marketed as "1Super Extenze," which they purchased in the United States. AIM: This series describes the clinical course and management of complications associated with the use of "1Super Extenze" in three Laotian men. METHODS: Surgeons excised all grossly affected tissue and performed reconstruction using skin grafting, Z-plasty, and tissue advancement, respectively. Tissue from the penile shaft of each patient and a local lymph node in one patient was examined microscopically. Mass spectroscopy was performed on an aliquot of "1Super Extenze." MAIN OUTCOME MEASURES: Urinary function, sexual function, and cosmesis of the three reported cases, chemical composition of "1Super Extenze," and microscopic analysis of penile and regional lymphatic tissue. RESULTS: Short-term cosmetic and functional outcomes were acceptable after surgical intervention. Histologic findings consistent with sclerosing lipogranulomas were seen in specimens from affected subcutaneous and lymphatic tissue. "1Super Extenze" proved to be composed of mineral oil with tocopherol acetate (vitamin E). CONCLUSION: Injection of "1Super Extenze" into the penile shaft results in sclerosing lipogranulomas, which can cause severe sexual and urinary complications. Surgical resection of all grossly involved tissue with appropriate reconstruction can mitigate these problems. This series supports previous recommendations in the literature that men should avoid the use of non-medical foreign bodies and fillers as means of penile augmentation.

RESUMO

Corticosteroids are the mainstay of therapy for atopic dermatitis, but long-term use is associated with adverse effects. We sought to evaluate the clinical efficacy of two steroid-sparing creams for atopic dermatitis. Twenty patients were enrolled in an investigator-blinded, bilateral comparison study. Patients applied pimecrolimus cream twice daily to a target lesion on one side of the body and also applied a topical medical device cream three times daily on a symmetrical target lesion on the opposite side of the body for four weeks. Clinical assessments including Physician Global Assessment (PGA), Target Lesion Symptom Score (TLSS), subject self-assessment and digital photography were performed at the baseline, 2 week, and 4 week visits. Seventy-five percent of patients (pimecrolimus, 15 of 20; topical medical device, 15 of 20) were rated "clear" (0) or "almost clear" (1) by PGA for both medications after four weeks. Percent improvement of the PGA from randomization for pimecrolimus cream and the topical medical device cream were 72.50 and 71.67 respectively (P=0.9283). PGA scores decreased significantly from baseline for both treatments (P=0.004). Overall, there was no statistically significant difference between treatment groups for PGA scores throughout the study (P=0.8236). No cutaneous side effects were noted. Our study was limited by a small sample size and lack of double-blinding; however, both treatments were found to be safe and effective in treating atopic dermatitis over four weeks. Significant improvements were noted for all efficacy variables. In conclusion, a lipid-rich, non-steroidal, topical medical device cream was as effective in improving atopic dermatitis as pimecrolimus cream.

RESUMO

Paraffin oil injection into the breast, which had been used for breast augmentation in the past, can cause various complications. Complete removal of paraffinoma lesions with immediate breast reconstruction using autogenous tissue is a very satisfactory treatment option. However, diffuse random distribution of paraffin oil through the subdermal layer makes it impossible to remove all of the lesions with overlying skin without resulting in a shortage of available skin and poor cosmesis. We herein report the case of a patient with breast cancer associated with paraffinoma, treated with skinsparing mastectomy and axillary node dissection with immediate extended latissimus dorsi flap reconstruction, resulting in good cosmetic outcome, and showing no complications during the wound-healing process.

RESUMO

Partial bowel obstruction is a serious complication of ascariasis infestation generally treated with mineral oil. This prospective study aimed to evaluate the efficacy of multiple bronchoalveolar lavages (BAL) as a therapeutic strategy for reducing lung inflammation of lipoid pneumonia associated with ascariasis. The study included five children (mean age 25 months) with partial small-bowel obstruction by Ascaris lumbricoides, who underwent diagnostic bronchoalveolar lavage for assessment of refractory pneumonia. Routine biochemical, microbiological and cytological analysis were carried out in the BAL. Protein, lactate dehydrogenase and tumor necrosis factor-alpha (TNF-α) cytokine levels were determined in the serum before and after treatment. At admission, children consistently had respiratory symptoms, altered hematological function, increased immunoglobulin E serum level and peripheral blood eosinophilia. Chest tomography showed consolidation with air bronchogram (4/4), ground-glass infiltration (3/4) and decreased attenuation in the consolidation areas (2/4). Presence of marked pleocytosis with Sudan positive foamy alveolar macrophages, high protein and lactate dehydrogenase levels in the BAL indicated presence of mixed alveolitis. One child with extensive consolidation and air bronchogram in both lungs died before treatment. Multiple bronchoalveolar lavages efficiently removed alveolar oil deposits, restored BAL cellularity, improved clinical symptoms, radiological parameters and further reduced inflammatory reaction evidenced by marked decrease of the inflammatory cytokine, TNF-α. This study presents a therapeutic strategy for management of lung complications caused by mineral oil administration to treat intestinal bowel obstruction associated with ascariasis.
