Blocking or enhancing effects of some basic emollients in UVA penetration

Abstract: Background: Topical agents used in combination with phototherapy or photochemotherapy may have both blocking or enhancing effects in ultraviolet rays. Objective: In this in vivo study, the effects of topical petrolatum, basis cream, glycerine, and olive oil on the transmission of ultraviolet A radiation were investigated. Methods: A test was performed to determine the minimal phototoxic dose on 29 volunteers with only psoralen plus ultraviolet A (PUVA) and then the same test was repeated with white petrolatum, basis cream, glycerine, olive oil, and sunscreen (0.3cc/25cm2). The effects of each agent on the minimal phototoxic dose were determined after 72 h. Results: When compared to pure PUVA, there was a statistically significant increase in the mean minimal phototoxic dose values by the application of white petrolatum (P = 0.011), but there was no significant increase or decrease in the mean minimal phototoxic dose values after the application of basis cream (P = 0.326), glycerine (P = 0.611) or olive oil (P = 0.799). Study limitations: Low number of patients Conclusion: The application of white petrolatum, which has a blocking effect, and also of basis cream immediately before PUVA therapy should not be recommended. Although we specify that glycerine and maybe olive oil can be used before photochemotherapy, there is a need for further research in larger series.

Retrospective Clinical Trial of Fusidic Acid versus Petrolatum in the Postprocedure Care of Clean Dermatologic Procedures

BACKGROUND: Clean dermatologic procedures create wounds with a low risk of infection (usually up to 5%). Whether the use of topical antibiotics is advocated, with regard to its efficacy and safety issues such as antibiotic resistance and sensitizing potential, is controversial. Fusidic acid, a topical antibiotic against gram-positive bacteria, is a rare sensitizer and commonly used in postprocedure care in Korea. OBJECTIVE: This is a retrospective study aimed at comparing the efficacy and safety between fusidic acid and petrolatum for the postprocedure care of clean dermatologic procedures. METHODS: Patients were treated with either fusidic acid or petrolatum ointment, applied on the wound created during clean dermatologic procedures such as biopsy of the punch, incisional, excisional, and shave types. The efficacy, adverse events, and subjective level of satisfaction were retrieved from medical records. RESULTS: A total of 414 patients with a total of 429 wounds were enrolled. The overall rate of adverse events was 0.9%, and the rates of adverse events in the fusidic acid group and the petrolatum group were 1.4% and 0.5%, respectively (p=0.370). There was no wound discharge, pain, tenderness, swelling, induration, or dehiscence in both groups. The patients' self-assessment of the wound was not significantly different between the two treatment groups. CONCLUSION: Our findings support the hypothesis that the routine prophylactic use of topical antibiotics is not indicated for clean dermatologic procedures. We recommend the use of petrolatum in the postoperative care of clean dermatologic procedures because of its equivalent efficacy and superior safety profiles.

A Case of Phthiriasis Palpebrarum Treated with Tea Tree Oil in a Child

PURPOSE: The authors of the present study report a case of phthiriasis palpebrarum treated with petrolatum ointment and tea tree oil in a 12-month-old boy. CASE SUMMARY: A bluish-gray macule and blood clots were found on the central portion of the upper eyelid of a boy who had rubbed his eyelid vigorously 1 week prior. Several 0.5 mm sized brownish-gray nits and 1.6 mm sized lice on the eyelashes were visible and was diagnosed with phthiriasis palpebrarum after light microscopic examination. The nits and lice were gently removed mechanically with the help of a white petrolatum ointment (Vaseline) and the eyelashes were cleaned with 50% tea tree oil. Nits and lice were successfully eradicated without recurrence 10 days after daily treatment with petrolatum ointment and 10% tea tree oil eyelash cleansing.

The use of liquid petroleum jelly in the prevention of perineal lacerations during birth / Uso de vaselina líquida en la prevención de laceracion perineal durante el parto / Uso de vaselina líquida na prevenção de laceração perineal durante o parto

Most of vaginal births are accompanied by lacerations in the genital tract. This was a randomized study carried out in a Birth Center located in São Paulo city to evaluate the efficacy of liquid petroleum jelly in reducing perineal laceration. The sample was composed of 38 nulliparous women per group (experimental and control). In the experimental group was used 30 ml of the petroleum jelly in the perineal region during the expulsive period. The parturient were allowed to push spontaneously during the delivery and remained in the left side position. The frequency of perineal laceration was similar in both groups (experimental 63.2 percent versus control 60.5 percent). The posterior perineum region presented the highest frequency of trauma (53.2 percent). Of the total cases of perineal trauma, 72.3 percent were first-degree lacerations. The use of liquid petroleum jelly of perineal protection does not reduce the frequency neither the degree of lacerations in childbirth.

La mayor parte de los nacimientos por vía vaginal están acompañados por laceraciones perineales. Este es un estudio aleatorio realizado en una maternidad de la ciudad de San Pablo para evaluar la eficacia de la vaselina líquida en la reducción de laceraciones perineales. La muestra fue compuesta por 38 mujeres nulíparas organizadas en un grupo experimental y otro de control. En el grupo experimental fue aplicado 30 ml de vaselina en la región perineal durante el periodo expulsivo. Todas las parturientas realizaron "pujos" espontáneos y se mantuvieron en la posición lateral izquierda. La frecuencia de laceración perineal fue semejante en ambos grupos (experimental 63,2 por ciento y grupo control 60.5 por ciento). La región posterior del perineo presentó una alta frecuencia de trauma (53.2 por ciento). De los casos totales de trauma perineal, 72,3 por ciento fueron de laceración de primer grado. Se verificó que el uso de la vaselina en la región perineal no reduce la frecuencia o grado de las laceraciones durante el parto.

A maioria dos partos vaginais é acompanhada por lacerações do trato genital. Este estudo randomizado foi realizado em um centro de parto normal localizado na cidade de São Paulo, para avaliar a eficácia da vaselina líquida em reduzir o trauma perineal. A amostra foi composta de 38 nulíparas por grupo (experimental e controle). No grupo experimental utilizaram-se 30 ml de vaselina líquida na região perineal durante o período expulsivo. Todas as parturientes realizaram "puxos" espontâneos e permaneceram em posição lateral esquerda. A freqüência de laceração perineal foi semelhante em ambos os grupos (experimental 63,2 por cento versus controle 60,5 por cento). A região posterior do períneo apresentou maior freqüência de trauma (53,2 por cento). Do total de casos de traumatismo perineal, 72,3 por cento foi de laceração de primeiro-grau.

A Case of Myospherulosis in the Nasal Septum / 대한이비인후과학회지

Myospherulosis is an unusual foreign-body reaction usually occurring in tissue exposed to petrolatum-based products. Since the initial description of myospherulosis of the paranasal sinus by Kyriakos in 1974, reported cases have been increasing. All of the lesions described by Kyriakos were located in the paranasal sinuses, nose, middle ear, or upper eyelid. However, there had not been any cases of myospherulosis reported in Korea. We report a case of myospherulosis in the nasal septum with a review of the related literature.
