RESUMEN

Even today, the mortality rate for uveal melanoma (UM) remains very high. In our research, we sought to determine which pathological and clinical features were correlated with the prognosis of UM. BAP1 (BRCA1-Associated Protein 1) gene mutation has been analyzed as one of the strongest predictors for metastasis in UM. The BAP1 gene codifies the BAP1 protein which has a tumor suppressor function. The presence of this protein can be determined by BAP1 immunohistochemical staining. Eighty-four uveal melanoma patients and forty enucleated eyeballs were examined. Metastasis was present in 24 patients. Nuclear BAP1 staining was low in 23 patients. The presence of a higher large basal diameter tumor (p < 0.001), tumor infiltrating lymphocytes (p = 0.020), and a lack of nuclear BAP1 immunostaining (p = 0.001) ocurred significantly more often in the metastatic group. Metastasis-free survival was lower in patients with low nuclear BAP1 staining (p = 0.003). In conclusion, to the best of our knowledge, this is the first time that BAP1 staining has been studied in uveal melanoma in a Spanish community. We believe that this technique should become routine in the pathological examination of uveal melanoma in order to allow adequate classification of patients and to establish an individual follow-up plan.

RESUMEN

Objective: To emphasize the importance of an early diagnosis and an adequate treatment in conjunctival tumors. Methods: We present two clinical cases and compare the course of each case: one of conjunctival intraepithelial neoplasia (CIN) which took a positive course, and a fatal case of squamous cell carcinoma (SCC) with intraocular and orbital extension. Results: Epithelial conjunctival malignancies are one of the most prevalent ocular surface tumors. Among these, CIN are the most common. CIN have an excellent prognosis, given adequate treatment. However, when the diagnosis of CIN is late, the epithelial basement membrane will be affected, resulting in SCC. SCC may have poorer results due to its capacity to infiltrate near tissues and create distant metastasis. Conclusion: It is not common today to treat patients with orbital extension of SCC; however, it is crucial to note the importance of an early diagnosis of conjunctival malignancies. An early diagnosis is essential to prevent the transformation to other life-threatening types.

RESUMEN

Objective: To report the occurrence and management of an eyelashes infestation by Phthirus pubis. Methods: A 27-year-old female presented with itching in her right eye and head after she had been traveling in southern Italy five days earlier. Visual acuity (VA) was 20/20 in both eyes. Slit-lamp examination showed bilateral blepharitis. Moreover, mobile insects and eggs attached to the eyelashes were observed. A microbiological study was performed with a Phthirus pubis result. The patient was treated with mechanical dislodging. Results: The resolution of the infection was carried out removing every insect and egg. A vaseline application twice daily for 7 days was necessary to stifle any nits that could remain. Conclusions: The eyelashes pediculosis is frequently caused by Phthirus pubis. Only a minor percentage of the cases are due to Phthirus capitis, but the differential diagnosis is essential: there are Phthirus pubis pediculosis cases due to sexual abuse. A sexual history and screening for other sexually transmitted diseases is warranted.

RESUMEN

The improper use of laser pointers, especially for recreational use in children, may cause sight-threatening retinal injuries. The retinal damage it is not well characterized because most publications are isolated cases or small series. The treatment and visual prognosis are variable according to the morphology of the macular damage. In some cases, there is no treatment, and spontaneous healing can be developed; however, others require surgery. In a series of 13 cases, 1 required surgery and the rest observation; 3 patients obtained a spontaneous healing with visual acuity of 10/10. We describe two patients aged 16 and 12 years with decreased visual acuity. Macular alterations appear in the fundus of the eye. The visual acuity of both recovered completely without treatment.


El uso indebido de los punteros láser, especialmente el recreativo en los niños, puede causar lesiones retinianas que amenazan la visión. El daño retiniano que producen no está bien caracterizado, debido a que la mayoría de las publicaciones son casos aislados o series pequeñas. El tratamiento y el pronóstico visual es variable según la morfología del daño macular que presenten. En algunos casos, no existe tratamiento, y pueden evolucionar a la curación espontánea; sin embargo, otros precisan cirugía. En una serie de 13 casos, uno requirió cirugía, mientras que el resto necesitó solo observación. De estos 13 casos, 3 pacientes se curaron en forma espontánea, con agudeza visual de 10/10. Se describen dos pacientes de 16 y 12 años con disminución de agudeza visual tras el uso indebido de punteros láser. En el fondo de ojo, presentaron alteraciones maculares. La agudeza visual de ambos se recuperó completamente sin tratamiento.

RESUMEN

Paciente de 14 años remitida para valorar fondo de ojo por cefalea. Presenta agudeza visual de 8/10 en ambos ojos y en fundoscopia se visualizan papilas de contornos escasamente definidos. Se solicita Autofluorescencia identificando lesiones autofluorescentes compatibles con drusas (Figura 1A,B). La OCT de fibras revela afectación sectorial bilateral sin papiledema (Figura 1C,D) y el campo visual mostró una afectación del hemicampo nasal bilateral (Figura 1E,F). Las drusas en el nervio óptico representan habitualmente un hallazgo casual. Pueden progresar paulatinamente generando gran deterioro campimétrico. No existe un tratamiento eficaz. Solo en casos donde aparezca neovascularización asociada, puede estar indicado el tratamiento con fármacos antiangiogénicos.
