RESUMEN

ABSTRACT Chlorpromazine is a medication widely used in psychiatry for the treatment of psychoses, especially schizophrenia. Since 1964, published articles have been correlating this medication with the appearance of ocular alterations. In this paper, we report the case of a 65-year-old patient with ocular effects due to long-term therapy with chlorpromazine. Biomicroscopy of both eyes presented diffuse granular brown deposits, most prominent at the deep stroma and corneal endothelium level. Also showed anterior subcapsular brown deposits with a stellate pattern in the lens. The total amount exceeds 2.000g (significant for the ocular alterations described) considering the patient's daily dosage of chlorpromazine of 300mg for ten years. After performing complete ophthalmic evaluation and discarding other causes for the ocular deposits, we diagnosed a secondary corneal deposit and cataract due to the use of chlorpromazine. This case reinforces the importance of periodic follow-up with an ophthalmologist for chlorpromazine users to trace ocular changes, heeding the exposure time and its dosage.


RESUMO A clorpromazina é uma medicação muito empregada na psiquiatria para tratamento de psicoses, especialmente em casos de esquizofrenia. Desde 1964 existem artigos publicados que correlacionam o uso dessa medicação com o aparecimento de alterações oculares. Neste trabalho, relatamos o caso de um paciente de 65 anos com efeitos oculares devido à terapia de longo prazo com clorpromazina. A biomicroscopia de ambos os olhos apresentou depósitos granulares difusos e de cor marrom, mais proeminente ao nível do estroma profundo e do endotélio da córnea, além de depósitos castanhos subcapsulares anteriores centrais em um padrão estrelado no cristalino. Considerando a dose diária de clorpromazina de 300mg por 10 anos usada pelo paciente, a quantidade total ultrapassa 2.000g (dose considerada significativa para as alterações oculares descritas). Após avaliação oftalmológica completa e descartado outras causas desses depósitos oculares, foram diagnosticados depósito corneano e catarata secundários ao uso de clorpromazina. O caso apresentado reforça a importância do acompanhamento oftalmolÓgico periÓdico de usuários de clorpromazina para o rastreio de alteraçÕes oculares, atentando-se ao tempo de exposição à droga e à posologia da mesma.

RESUMEN

An unusual grayish brown discoloration of the synovium was found during a knee arthroscopy of a 72-year-old man. He also had similar pigmentation affecting the skin on the legs, arms, hands, and face. It was found he had been taking 400 mg of amiodarone hydrochloride daily for last 7 years. Amiodarone is known to cause a slate grey pigmentation of skin and cornea, but we believe this is the first report of amiodarone-induced pigmentation of the synovium. The arthroscopist should be aware of the possibility of drug-related synovial pigmentation and include this in differential diagnosis.

RESUMEN

Reticulate pigmentary disorders is a term that is loosely defined to include a spectrum of acquired and congenital conditions with different morphologies. The presentations vary from the reticular or net like pattern to the" freckle like" hyper and hypopigmented macules that are usually restricted to the true genetic "reticulate" pigmentary disorders. There is little clarity on this topic and related terms, in major dermatology textbooks. Hence, to harmonize the different entities we feel that the term "mottled pigmentation" could be used to include reticulate pigmentary disorders (acquired and congenital), dyschromasias and the disorders with a reticular pattern. The genetic reticulate pigmentary disorders can also be classified according to the gene loci which in the majority of cases are localized to keratin 5/14. A more useful clinical method of classification is based on the regional distribution, which includes facial, truncal, acral or flexural types. In this review we will largely focus on the inherited reticulate pigmentary disorders.

RESUMEN

To investigate the protective effects of Pomegranate on Minocycline induced epidermal pigmentation on the extremities of guinea pigs. An experimental observational study. This study was conducted at the Anatomy Department, BMSI, J PMC, Karachi. 60 adult guinea pigs were divided into 3 groups A B and C, A served as control, B given Minocycline, while C given Minocycline with pomegranate for 8 weeks, after which their skin was processed for histological examination and pigmentation was observed in Masson Fontana stained sections under light microscope. The melanin pigmentation deposition observed in Minocycline treated group B, distributed densely and extended till stratum corneum as compared to the control group A, while in the Pomegranate treated group c along with Minocycline, the melanin pigmentation was considerably reduced and was observed to be distributed sparsely extended till stratum spinosum. Based on the present study it is conducted that pigmentary changes induced by Minocycline can be protected by taking pomegranate

RESUMEN

Tatuagens por amálgama são lesões pigmentadas, exógenas, de frequente ocorrência na mucosa bucal, que resultam da introdução acidental de partículas de amálgama nos tecidos moles. O diagnóstico da tatuagem por amálgama é simples, geralmente, baseado em achados clínicos, complementado pela história recente ou pregressa de remoção de restauração por amálgama. Radiografias intraorais podem ser úteis na detecção de radiopacidade, associadas à partícula de amálgama. Nos casos em que as tatuagens por amálgama não permitem diferenciação de outras lesões melanocíticas, o exame histopatológico deve ser realizado. Os autores relatam à ocorrência de lesão extensa por tatuagem de amálgama com confirmação histopatológica.


Amalgam tattoos are common exogenous pigmented lesions of the oral mucosa occurring mainly by inadvertent placement of amalgam particles into soft tissues. The diagnosis of amalgam tattoo is simple, usually based on clinical findings associated with presence or history of amalgam fillings removal. Intraoral X-rays may be helpful in detecting amalgam-related radiopacity. In cases where amalgam tattoo cannot be differentiated from other causes of oral pigmentation, a biopsy should be performed. This article deals with an extensive amalgam tattoo lesion which required a biopsy for a definitive diagnosis.

RESUMEN

Contact dermatitis from natural latex of condom has been reported and is attributed to latex sensitivity. Chemical leukoderma from rubber condom is probably not reported. Here we present a case of chemical leukoderma in a 32-year-old male who developed depigmentation around the shaft of the penis in a circumferential pattern. Since the lesion was solitary and the site corresponded to the point of maximum contact of the condom, a diagnosis of contact leukoderma due to latex condom was thought of. Patch testing was done with mercaptobenzothiazole (MBT), dusting powder present in the condom and condom latex as such. The patient tested positive (3+) with mercaptobenzothiazole and the condom latex. On discontinuation of condom use and with UVB phototherapy, lesions repigmented in eight weeks.

RESUMEN

The most common health effects from drinking-water containing dissolved arsenic are skin abnormalities and lesions that are typically diagnosed as keratosis and pigment disorder. It was previously reported that the prevalence of cutaneous lesions was about 44% in arsenic-affected villages. However, there has been little research on the relationship between levels of arsenic in drinking-water and cutaneous lesions in Inner Mongolia. One study examined the association between the prevalence of keratosis and levels of arsenic exposure and the relationship between pigment disorder and levels of arsenic exposure among villagers aged 18 years or older in the arsenic-affected village of Hetao Plain in Inner Mongolia, PR China. The study included 227 participants who were affected by cutaneous lesions and 221 participants who were not affected by cutaneous lesions diagnosed in 1996 and 1998. Well-water drunk by the participants was collected to analyze arsenic content. Adjusting for age, sex, and smoking, logistic regression was applied to calculate the risks that arsenic in drinking-water will lead to cutaneous lesions. The results from the logistic regression showed that, with the increase of arsenic concentration in water, the risk of pigment disorder also increased (odds ratio [OR]=5.25, 95% confidence interval [CI] 1.32-83.24 for 50-199 microg/L; OR=10.97, 95% CI 1.50-79.95 for 200-499 [microg/L; OR=10.00, 95% CI 1.39-71.77 for > or = 500 microg/L (p=0.000), but the association between risk of keratosis and levels of arsenic was not significant (p=0.346). The findings suggest that keratosis is an early feature of arsenic poisoning, and the development of pigment disorder depends on higher doses of arsenic intake rather than keratosis. Further studies are needed to confirm that cutaneous lesions and other adverse health effects occur at low levels of arsenic exposure.

RESUMEN

El clorhidrato de amiodarona es un agente antiarrítmico con efectos secundarios cutáneos conocidos. Un grupo multidisciplinario de especialistas estudió durante 2 años a 148 pacientes en tratamiento crónico con amiodarona, con el propósito de evaluar los efectos secundarios del fármaco. Todos los pacientes fueron examinados por el mismo dermatólogo, buscando la presencia de alteraciones cutáneas y su correlación con la dosis y duración del tratamiento; 79 eran mujeres, con un promedio de edad de 65 años. Las dosis de amiodarona comprendían un rango de 100 a 400 mg/día. Los pacientes fueron controlados durante 2 años, pero el período de terapia con amiodarona fue de 1 a 9 años. Se encontró fotosensibilidad en 39,3 por ciento de los pacientes, hiperpigmentación azul-grisácea en 10 por ciento , ambos sin relación con la dosis. La presencia de eritema facial se constató en el 24 por ciento de los casos y se estableció que existía relación con la dosis. Un paciente debió suspender la terapia debido a una erupción pruriginosa de placas infiltrativas, las que regresaron completamente al suspender fármacos. 76 por ciento de los pacientes presentaban uno o más trastornos cutáneos diferentes de los relacionados con la miodarona. Estos incluyen micosis de pies y uñas, queratosis actínicas y seborreicas, xerosis y distrofias ungueales. Los efectos secundarios cutáneos son muy comunes y bien tolerados en los pacientes en terapia con amiodarona. La suspensión del tratamiento debido a los efectos secundarios cutáneos fue poco frecuente
