Comparative Study between Acacia Nilotica versus Povidone Iodine in Topical Treatment of Omphalocele Major.

Well established and common practice in conservative management of omphalocele major is escharotics therapy with different topical agents. Among them mercurochrome, alcohol, silver salts, povidone iodine, acacia nilotca paste are commonly used. It is a comparative study between application of acacia nilotica paste and povidone iodine solution as a primary non surgical treatment of omphalocele major regarding efficacy and safety of these two topical agents. A double blind randomized controlled study was conducted at the department of Paediatric Surgery, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from July 2016 to June 2019. In this study 20 cases of omphalocele major and randomly divided into two equal groups. Group A and Group B treated with acacia nilotica paste and povidone iodine solution respectively. Gastroschisis, ruptured-omphalocele major or omphalocele minor excluded in this study. The size of the fascial defect in cm, time required for full oral feeding tolerance and duration of hospital stay were evaluating parameters. Patients with Group A tolerated full oral feeding earlier, shorter total hospital stay duration and low mortality rate than those from Group B. Application of acacia nilotica is a safe and effective treatment of omphalocele major regarding rapid full oral feeding tolerance, shorter hospital stay and low mortality rate.

Auditory and Histopathological Effects of Topical Mercurochrome Treatment in Rats with Tympanic Membrane Perforation.

OBJECTIVES: Topical treatment is first choice in the treatment of uncomplicated chronic otitis media. It was intended to assess auditory and histopathological safety of ototopical use of mercurochrome solution in rats with induced tympanic membrane perforation. MATERIALS AND METHODS: The study was conducted on 21 female Wistar-Albino rats which were randomly assigned into 3 groups. In all rats, perforation was performed at right tympanic membrane. Distortion product otoacoustic emissions (DPOAEs) measurements were performed at frequencies of 2000, 3000 and 4000 Hz (with L1/L2: 70 /70 dB at 2f1-f2 frequency; f2/f1 ratio: 1:22) before recovery from anesthesia and signal-to-noise ratio (SNR) were recorded. Normal saline, 2% mercurochrome and gentamicin were given to group 1, 2 and 3 twice daily over a week, respectively. Rats were sacrificed after DPOAE measurements on day 14. Right temporal bone specimens were examined under light microscope after processing. RESULTS: Based on DPOAE results, there was no significant difference among groups before treatment. On day 14, significant differences were found in DPOAE measurements at 3000 and 4000 Hz, and in mean SNR values in 2% mercurochrome and gentamicin groups when compared to normal saline group while no significant difference was detected at 2000 Hz among groups. In addition, significant degeneration was detected in Corti organs, spiral ganglions and stria vascularis in groups 2 and 3. CONCLUSION: In this study, it was observed that mercurochrome use in external otitis and otitis media with tympanic membrane perforation could cause ototoxicity and concluded that the solution should be used cautiously.

Antiseptics for burns.

BACKGROUND: Burn wounds cause high levels of morbidity and mortality worldwide. People with burns are particularly vulnerable to infections; over 75% of all burn deaths (after initial resuscitation) result from infection. Antiseptics are topical agents that act to prevent growth of micro-organisms. A wide range are used with the intention of preventing infection and promoting healing of burn wounds. OBJECTIVES: To assess the effects and safety of antiseptics for the treatment of burns in any care setting. SEARCH METHODS: In September 2016 we searched the Cochrane Wounds Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), Ovid MEDLINE, Ovid MEDLINE (In-Process & Other Non-Indexed Citations), Ovid Embase, and EBSCO CINAHL. We also searched three clinical trials registries and references of included studies and relevant systematic reviews. There were no restrictions based on language, date of publication or study setting. SELECTION CRITERIA: We included randomised controlled trials (RCTs) that enrolled people with any burn wound and assessed the use of a topical treatment with antiseptic properties. DATA COLLECTION AND ANALYSIS: Two review authors independently performed study selection, risk of bias assessment and data extraction. MAIN RESULTS: We included 56 RCTs with 5807 randomised participants. Almost all trials had poorly reported methodology, meaning that it is unclear whether they were at high risk of bias. In many cases the primary review outcomes, wound healing and infection, were not reported, or were reported incompletely.Most trials enrolled people with recent burns, described as second-degree and less than 40% of total body surface area; most participants were adults. Antiseptic agents assessed were: silver-based, honey, Aloe Vera, iodine-based, chlorhexidine or polyhexanide (biguanides), sodium hypochlorite, merbromin, ethacridine lactate, cerium nitrate and Arnebia euchroma. Most studies compared antiseptic with a topical antibiotic, primarily silver sulfadiazine (SSD); others compared antiseptic with a non-antibacterial treatment or another antiseptic. Most evidence was assessed as low or very low certainty, often because of imprecision resulting from few participants, low event rates, or both, often in single studies. Antiseptics versus topical antibioticsCompared with the topical antibiotic, SSD, there is low certainty evidence that, on average, there is no clear difference in the hazard of healing (chance of healing over time), between silver-based antiseptics and SSD (HR 1.25, 95% CI 0.94 to 1.67; I2 = 0%; 3 studies; 259 participants); silver-based antiseptics may, on average, increase the number of healing events over 21 or 28 days' follow-up (RR 1.17 95% CI 1.00 to 1.37; I2 = 45%; 5 studies; 408 participants) and may, on average, reduce mean time to healing (difference in means -3.33 days; 95% CI -4.96 to -1.70; I2 = 87%; 10 studies; 979 participants).There is moderate certainty evidence that, on average, burns treated with honey are probably more likely to heal over time compared with topical antibiotics (HR 2.45, 95% CI 1.71 to 3.52; I2 = 66%; 5 studies; 140 participants).There is low certainty evidence from single trials that sodium hypochlorite may, on average, slightly reduce mean time to healing compared with SSD (difference in means -2.10 days, 95% CI -3.87 to -0.33, 10 participants (20 burns)) as may merbromin compared with zinc sulfadiazine (difference in means -3.48 days, 95% CI -6.85 to -0.11, 50 relevant participants). Other comparisons with low or very low certainty evidence did not find clear differences between groups.Most comparisons did not report data on infection. Based on the available data we cannot be certain if antiseptic treatments increase or reduce the risk of infection compared with topical antibiotics (very low certainty evidence). Antiseptics versus alternative antisepticsThere may be some reduction in mean time to healing for wounds treated with povidone iodine compared with chlorhexidine (MD -2.21 days, 95% CI 0.34 to 4.08). Other evidence showed no clear differences and is of low or very low certainty. Antiseptics versus non-antibacterial comparatorsWe found high certainty evidence that treating burns with honey, on average, reduced mean times to healing in comparison with non-antibacterial treatments (difference in means -5.3 days, 95% CI -6.30 to -4.34; I2 = 71%; 4 studies; 1156 participants) but this comparison included some unconventional treatments such as amniotic membrane and potato peel. There is moderate certainty evidence that honey probably also increases the likelihood of wounds healing over time compared to unconventional anti-bacterial treatments (HR 2.86, 95% C 1.60 to 5.11; I2 = 50%; 2 studies; 154 participants).There is moderate certainty evidence that, on average, burns treated with nanocrystalline silver dressings probably have a slightly shorter mean time to healing than those treated with Vaseline gauze (difference in means -3.49 days, 95% CI -4.46 to -2.52; I2 = 0%; 2 studies, 204 participants), but low certainty evidence that there may be little or no difference in numbers of healing events at 14 days between burns treated with silver xenograft or paraffin gauze (RR 1.13, 95% CI 0.59 to 2.16 1 study; 32 participants). Other comparisons represented low or very low certainty evidence.It is uncertain whether infection rates in burns treated with either silver-based antiseptics or honey differ compared with non-antimicrobial treatments (very low certainty evidence). There is probably no difference in infection rates between an iodine-based treatment compared with moist exposed burn ointment (moderate certainty evidence). It is also uncertain whether infection rates differ for SSD plus cerium nitrate, compared with SSD alone (low certainty evidence).Mortality was low where reported. Most comparisons provided low certainty evidence that there may be little or no difference between many treatments. There may be fewer deaths in groups treated with cerium nitrate plus SSD compared with SSD alone (RR 0.22, 95% CI 0.05 to 0.99; I2 = 0%, 2 studies, 214 participants) (low certainty evidence). AUTHORS' CONCLUSIONS: It was often uncertain whether antiseptics were associated with any difference in healing, infections, or other outcomes. Where there is moderate or high certainty evidence, decision makers need to consider the applicability of the evidence from the comparison to their patients. Reporting was poor, to the extent that we are not confident that most trials are free from risk of bias.

Special Treatment and Wound Care of the Driveline Exit Site after Left Ventricular Assist Device Implantation.

OBJECTIVE: Despite good results following implantation of left ventricular assist devices (LVADs), infections of the driveline and device pocket remain a major problem for patients on long-term support. We present the data from heart failure patients treated with a Thoratec HeartMate-II LVAD (Thoratec Corporation, Pleasanton, California, United States). METHODS: From January 2008 to April 2011, in our institution, 40 heart failure patients (NYHA IV) were supported with a HeartMate-II LVAD. The driveline maintenance of 17 patients consisted of the use of Octenidine for the wound dressing, whereas merbromin was additionally used for local irrigation in 31 patients. The data concerning driveline infections were analyzed retrospectively. RESULTS: In our study, 95% of the entire cohort was free from infections of the system. Two patients in the conventional group (11.8%) developed a driveline infection at a mean of 130.5 days during 3,416 patient-days (0.21 infection/patient-years). In the Merbromid group (Co. New FaDem SRL Farmaceutici & Chimici, Giugliano, Campania, Italy), all patients were free from any driveline infections during the observation period. In a log-rank comparison, the difference reached statistical significance (p = 0.043). CONCLUSION: During our observation period, fewer infections were noted with merbromin treatment. A multicenter setting in a larger cohort should be performed to confirm these findings, although a (double-) blinded setting might be difficult to achieve.

Otomycosis: clinical and mycological study of 97 cases.

OBJECTIVE: To report otomycosis in a retrospective study and correlate clinical, epidemiological and therapeutic factors. MATERIAL AND METHOD: This study comprises 97 cases of clinically and mycologically proven otomycosis or fungal otitis externa gathered during a 12-year period. RESULTS: Most cases were unilateral (90.7%) and the main predisposing factors associated with the disease were trauma (secondary to the constant scratching) and the use of topical antibiotics. Major causal agents were several species of Aspergillus (63.9%), of which Aspergillus flavus was commonest (26%), followed by Candida albicans (26.8%) and Aspergillus niger (21%). CONCLUSION: The treatment of choice is mainly local toilet of the external auditory canal and the use of systemic antifungal agents to prevent re-infection and the spread of disease.

Chronic bilateral otomycosis caused by Aspergillus niger.

Aspergillus niger, an opportunistic filamentous fungus, was identified as the cause of chronic bilateral otomycosis in a 46-year-old female patient who was unresponsive to different drugs. The patient showed signs of erythema, otalgia, itching, otorrhoea and presence of greyish black coloured mass in both the ear canals. The direct microscopical examination of the ear debris in potassium hydroxide preparations, Giemsa, phase contrast and Gram revealed many thin, branched septate hyphae, condia and conidiophores morphologically indistinguishable from Aspergillus spp. The histopathological section of the ear wax mass by haematoxylin and eosin and periodic acid-Schiff techniques also showed similar fungal elements. The patient responded to 1% solution of mercurochrome. The use of mercurochrome in developing countries like India may be recommended to treat the fungal otitis in patients. We also emphasize that 'Narayan' stain should be routinely employed by microbiology and public health laboratories to study the morphology of pathogenic fungi.

Eficacia de una aplicación frente a tres de merbromina en el tiempo de caída del cordón / Efficacy of one versus three applications of merbromin in achieving umbilical cord detachment

Objetivo: comparar la eficacia de dos pautas de aplicación de la merbromina (una aplicación diaria frente a tres) en el tiempo de caída del cordón umbilical. Método: un total de 285 neonatos fueron asignados aleatoriamente a uno de los dos grupos de estudio. Se obtuvo información completa de 280 neonatos (145 en el grupo de tres aplicaciones y 135 en el grupo de una aplicación). Se recogieron las siguientes variables: tipo de parto, peso y apgar del recién nacido, días hasta la caída del cordón, efectos adversos, grado de dificultad de la cura del ombligo y preocupación de los padres. Resultados: en el grupo de tres aplicaciones de membromina diarias la caída del cordón se produjo a los 10,8 +/- 6,1 días, mientras que en el grupo de una aplicación fue a los 8,8 +/- 3,9 días (9<0,001). No se detectó ningún cado de onfalitis ni alergias. No se observaron diferencias significativas en la aparición de granulomas (4,1 por ciento en el grupo de tres aplicaciones y 3,7 por ciento en el de una aplicación ). Conclusiones: una única aplicación diaria de merbromina en el cuidado umbilical presenta un buen efecto curativo, menor tiempo de caída del cordón, menor coste y mayor seguridad para los padres (AU)

Otomycosis in Nigeria: treatment with mercurochrome.

Seventy-two mycologically proven cases of otomycosis (38 males, 34 females) aged 8-80 years were investigated. Aspergillus niger was the commonest aetiological agent (43.1%) followed by Candida spp. (22.2%), A. flavus (19.4%) and A. fumigatus (15.3%). Three topical drugs, namely mercurochrome, clotrimazole and locacorten-vioform, were evaluated for otomycosis therapy in separate groups of 24 patients each. Mercurochrome was found to be the most efficacious in terms of healing, relief from symptoms of the disease and production of negative fungal cultures. Mercurochrome is recommended as a safe and economical drug for the topical treatment of otomycosis in developing countries like Nigeria.

Successful treatment of transient acantholytic dermatosis with systemic steroids.

A sixty-year-old man, developed 2-5 mm sized, hyperemic, itchy papules, vesicles, erosions and crusts on hyperemic base on his chest, abdomen, back, gluteal region, and proximal sites of his upper and lower extremities. The direct and indirect immunoflurescence tests were negative. Histology revealed extensive acantholysis in the epidermis in the following forms: pemphigus vulgaris-like suprabasal acantholysis, Darier-like acantholytic dyskeratosis with corps ronds, Hailey-Hailey-like suprabasal clefts, and pemphigus foliaceus-like superficial acantholysis with spongiosis. Using systemic steroids, topical drying, and reepithelising therapy, the patient was cured. He was symptom-free the first, fourth, and thirteenth months after finishing steroid therapy. We review the literature and the new subdivision of the disease according to the histological and clinical features.

Otomycosis--a clinico-mycological study and efficacy of mercurochrome in its treatment.

A total of 110 patients of symptomatic otomycosis was investigated, prospectively. Aural swabs were collected on 1st, 7th and 14th day and examined by direct microscopy and culture for fungi. Of these, 80 patients found to be having pure fungal infection, were taken up for mycological and therapeutic study. Fungi belonging to genus Aspergillus were isolated in 76 (95.0%) patients of which Aspergillus niger was the commonest isolate in 46 (57.5%), followed by A. flavus in 27 (33.7%), A. fumigatus in 3 (3.7%), Candida species in 3 (3.7%) and Mucor in 1 (1.2%). The patients were of all age groups but majority were between 21 and 30 years and the male-female ratio was equal. Of the total of 40 male patients, twenty-one were Sikhs using turban. Before developing the symptoms, forty five patients used oil, mixture of oil and garlic juice, antibiotics, steroids, antiseptics or wax solvent as ear drops. Only two patients were diabetic. No patient had fungal infection elsewhere in the body. The patients were called for regular follow-up for three weeks. In forty cases mercurochrome was applied as the antifungal agent after cleaning the external auditory canal, in twenty-three clotrimazole and in rest of the seventeen patients miconazole was used. On 7th day, only 11 (13.7%) patients grew different fungi in culture. They became symptom-free on 14th day and no fungal material could be seen on otoscopy, direct microscopy or culture. Mercurochrome was found to be most effective in these patients.

Improving the results of facial dermal lesions elimination by laser.

Argon laser therapy of superficial pigmented lesions in both young and old people is associated with a risk of complications including delayed wound closure and hypo/hypertrophic scarring. Problems may also occur after treatment of lesions located on the eyelid. To minimize the risk of these problems coagulation of deep tissue should be avoided. We discuss a technique using mercurochrome, a red-colored compound that absorbs the blue and green lines of the argon laser, as a barrier for the irradiated light that eliminates these complications and we provide probable reasons for this technique's effectiveness.

Evaluation of conservative therapy for exomphalos.

Two management patterns were identified in 36 patients with exomphalos--primary surgical closure and initial topical therapy with delayed surgical closure. Primary surgical closure of minor exomphalos was well tolerated in 15 patients, but was associated with a high local and systemic morbidity rate in 14 patients with major defects. In contrast, initial topical therapy with silver sulphadiazine and delayed closure in seven matched patients with a major defect were well tolerated and did not prolong duration of hospitalization. Enteral feeding was more readily established and subsequent fascial closure facilitated in the conservatively treated group. It was suggested that this method should be more often considered in the management of all instances of major exomphalos.

No grupo IV foi feita uma associaçäo do salicilato de sódio e sulfadiazinato de zinco. A análise estatística dos resultados mostrou näo haver diferença significativa entre os diversos grupos, quando se toma em consideraçäo o tempo necessário para a completa epitelizaçäo das lesÆes

Use of mercurochrome in the management of the large exomphalos.

The topical application of solutions containing mercury has remained popular in the conservative management of the large exomphalos, despite recent reports of high organ mercury levels occurring in neonates who have died following this type of treatment. There are few reports of mercury poisoning being recognized in survivors. This report records blood and urine mercury levels in four patients with no apparent sequelae after treatment with Mercurochrome and provides guidelines for the safer use of mercurial solutions in the conservative management of exomphalos: one thin application of 1% Mercurochrome be applied to the intact sac; thereafter, Mercurochrome be applied sparingly only to areas that remain moist; blood and urine levels of mercury be monitored routinely; and applications ceased whenever mercury levels exceed the minimum toxic level. Only with this sparing and judicious use of mercurial solutions is the hazard to the infant kept to a minimum.

Topical treatment of experimental skin lesions in rats: macroscopic, microscopic and scanning electron-microscopic evaluation of the healing process.

The effects of the topical antiseptic agents mercurochrome and silver nitrate and of sodium hyaluronate on the process of wound healing were assessed by macroscopic examination, light microscopy histology, electron microscopy and scanning electron microscopy of wounds made by cutting or by abrasion of the skin of rats. It was found that wounds treated with hyaluronic acid underwent longer periods of inflammation (proportional to the presence of mastocytes) and greater amounts of collagen deposition than wounds that were either untreated controls or treated with silver nitrate or mercurochrome, but this did not impede the formation in the early stages of healing of bridges of fibrin between the edges of the wounds.

[Lyell's syndrome: study of a clinical case]. / Sindrome di Lyell: considerzioni su di un caso clinico.

The Authors report a case of Lyell's syndrome. Previous administration of sulfadossine was identified as the precipitating cause of the syndrome. The clinical history and the treatment of the case are described. Two aspects of the latter were considered to be particularly important: a careful control of the hydroelectrolytic balance and positive action to favour the rapid re-epithelialization of the cutaneous area affected.
