RESUMO
BACKGROUND: Woolly Hair Syndrome (WHS) is a rare birth condition that affects the structure of hair in non-black people. The pathogenesis is not yet defined. It is postulated that the hair follicle's desmosomes (specifically desmoplaquine, placoglobin and placofilin-1, which are cell structural proteins that keep the adhesion among close cells) would be altered in this pathology, leading to fragility in the cellular union. It is subdivided into two large groups: the localized or circumscribed variant and the generalized variant. From birth or first months of life, patients with WHS are clinically characterized by the presence of a portion or entire scalp area of very short frizzy hair, usually of a smaller diameter, brittle and lighter color. The most frequent skin manifestations are pilar keratosis and palmo-plantar keratodermia. The diagnosis is based on the clinical findings, and it is facilitated by trichotoscopic examination. However, a definitive diagnosis of WHS requires genetic testing. Oral agenesis, enamel defects (such as hypomineralization), atypical caries, dental inclusion, and malformed pin-shaped teeth may occur. OBJECTIVE: To describe an aesthetic alternative of oral rehabilitation using the mock-up technique in a patient with WHS. CLINICAL CASE: A 5-year-old female patient diagnosed with WHS from the National Institute of Child Health NIHCH: Breña, Lima, who was referred from the Genetic service to the Pediatric Dentistry service in order to screen outbreaks of infection associated with odontogenic origin and dental anomalies. At the ectoscopy, a patient with short capillary length, brittle and curly hair, dry skin, and nail dystrophy was observed. At the intraoral clinical examination, anterior pieces of 52, 51, 61, 62, and enamel hypomineralization were observed in all teeth. The radiographic examination showed agenesis of parts 41, 34, and 45. Integral dental treatment was performed in the operating room under general anesthesia due to the complexity of the case. Pulpectomy in pieces 52, 51, 61, 62, post of composite resin, and rehabilitation with supra-nanow filling resin using the mock-up technique were proposed as alternative treatments. CONCLUSION: The making of supra-nano filling resin-based crowns using the mock-up technique is an alternative treatment for aesthetic oral rehabilitation in deciduous dentition of patients with WHS. The aesthetic treatment was achieved using supra nano-filling resins. After 12 months of dental treatment, a favorable response was observed, improving the chewing, phonation and aesthetics of the patient.

La osteotomía de Pemberton es utilizada para el tratamiento de la subluxación de la cadera en artritis séptica infantil de la cadera. Las caderas presentaban deformidad de la cabeza femoral asociada a necrosis avascular secundario a la artritis séptica; clasificamos la cadera como tipo Choi I B. secuelas. La edad en la cual fue sometida a cirugía fue a los 8 días de nacido con debridamiento quirúrgico, a los 6 meses mediante capsuloplastia y yeso pelvi pedico y a los 3 años osteotomía de Pemberton con un período de seguimiento promedio de 3 años. Se obtuvieron las reducciones concéntricas. El resultado fue satisfactorio según los criterios de Hunka en el momento del seguimiento más reciente. En la última radiografía de seguimiento la cadera tenía contención exitosa de la cabeza femoral. Mediante el presente caso proponemos osteotomía de Pemberton un procedimiento efectivo para el tratamiento de las secuelas de artritis séptica, y la reconstrucción del techo acetabular por la secuela de la artritis séptica cadera infantil, siempre que se pueda lograr una reducción concéntrica.
The Pemberton osteotomy is used for the treatment of hip subluxation in infantile septic arthritis of the hip. The hips presented deformity of the femoral head associated with avascular necrosis secondary to septic arthritis. We classify the hip as Choi I B. sequelae. The age at which she underwent surgery was 8 days old with surgical debridement, at 6 months with capsuloplasty and pelvic plaster, and at 3 years with Pemberton osteotomy, and the average follow-up period was 3 years. The concentric reductions were obtained. The result was satisfactory according to the Hunka criteria at the time of the most recent follow-up. On the most recent follow-up radiograph the hip had successful femoral head containment. Through the present case, we propose Pemberton osteotomy, an effective procedure for the treatment of the sequelae of septic arthritis, and the reconstruction of the acetabular roof due to the sequelae of septic arthritis in the infantile hip, provided that a concentric reduction can be achieved.

Focal Adhesion Kinase (FAK) is a 125-kDa cytoplasmic protein kinase that is implicated in several cellular functions. This protein is an attractive molecular target for cancer therapy because a wide variety of studies have demonstrated associations between the activation or elevated expression of FAK and tumor progression, invasion, and drug resistance in malignant tumors. Here, we review the strategies used to inhibit FAK activity in solid tumors. We also include an overview of the preclinical (in vitro and in vivo) and clinical studies on FAK inhibitors.

The seventh session of the Oncological Pathology Conference (JoPaO) entitled 'Pathological Anatomy in the context of the National Cancer Law: An overview of the Latin American experience', was held virtually on July 15, 22 and 23. Peru was the headquarters for this event, where 17 national and international professors of high academic standing participated. They interacted in a multidisciplinary context through talks with national panellists and the general public. The recent promulgation of the 'National Cancer Law' fosters the development of discussion forums to analyse the national realities and uphold continuous learning about experiences in other Latin American countries with successful cancer programmes, in which pathology holds a principal role. The topics addressed during this JoPaO included the exchange of Latin American cancer management experiences, an emphasis on investments in and the development of strategic plans to improve care, the use of new technologies, laboratory quality control, and the need to advance scientific research.
RESUMO
La viruela símica (VS) es una enfermedad viral, zoonótica que afecta principalmente a los primates y se transmite a humanos. Dicho virus fue aislado inicialmente de un mono de laboratorio en la República Democrática del Congo en 1970 y a partir de allí, ha circulado en el continente africano, principalmente en República Democrática del Congo, Sudán del Sur, Camerún, República Centroafricana, Liberia, Nigeria, Sierra Leona y República del Congo; durante las últimas cinco décadas. Desde el año 2003 se reportaron casos fuera de África, específicamente en Estados Unidos, Reino Unido, Israel y Singapur; mientras que en mayo de 2022, la OMS; reportó un brote de VS humano en varios países de Europa y América, con más de 38000 casos en 93 países y cinco muertes en África, además de la ausencia de vínculos directos con países endémicos y un cambio en el patrón de transmisión; lo que conllevó al organismo a declarar el brote como emergencia de salud pública de interés internacional. La VS cursa con fiebre, cefalea, mialgias, linfadenopatia y lesiones dérmicas; y aunque la enfermedad no es fácilmente transmisible con tendencia a la curación espontánea; los casos observados actualmente no son típicos, con lesiones similares a las producidas por la viruela humana. La presente revisión tiene el objetivo de actualizar los conocimientos acerca de los rasgos clínicos y epidemiológicos de la VS, para comprender la presentación del brote actual y brindar herramientas que permitan diagnosticar y tratar eficazmente a los pacientes afectados(AU)
Monkeypox (MPX) is a viral, zoonotic disease that mainly affects primates and is transmitted to humans. This virus was initially isolated from a laboratory monkey in the Democratic Republic of the Congo in 1970 and since then has circulated on the African continent, mainly in the Democratic Republic of the Congo, South Sudan, Cameroon, the Central African Republic, Liberia, Nigeria, Sierra Leone, and Republic of the Congo; during the last five decades. Since 2003, cases have been reported outside of Africa, specifically in the United States, the United Kingdom, Israel, and Singapore; while in May 2022, the WHO; reported an outbreak of human MPX in several countries in Europe and America, with more than 38,000 cases in 93 countries and five deaths in Africa, in addition to the absence of direct links with endemic countries and a change in the pattern of transmission; which led the agency to declare the outbreak a public health emergency of international concern. MPX presents with fever, headache, myalgia, lymphadenopathy, and skin lesions; and although the disease is not easily transmissible with a tendency to spontaneous healing; the cases currently observed are not typical, with lesions similar to those produced by smallpox. This review aims to update knowledge about the clinical and epidemiological features of MPX, to understand the presentation of the current outbreak and provide tools that allow effective diagnosis and treatment of affected patients(AU)

Ophthalmomyiasis is the ocular infestation by dipterous larvae. It has been described in patients from rural areas, poor hygiene, or contact with animals. However, there are sporadic reports of this infestation in urban areas. We present the case of a young man without risk factors, from an urban area in southern Peru, in whom we found 10 larvae at ocular conjunctiva. The larvae were identified as Oestrus ovis, a fly that usually infests sheep and goats as part of their life cycle. We made a brief review of the case, highlighting the importance of adequately identifying the species that cause myiasis as well as its life cycle.

Survivin protein is a metalloprotein member of the inhibitors of apoptosis proteins family, involved in the regulation of programmed cell death. Due to the recent development of antitumor therapies having survivin as molecular target, several strategies to interfere with the expression or function of survivin have emerged. This work describes the discovery of a new potential inhibitor of survivin function using a computer-aided drug design approach. Structure-based virtual screening and molecular dynamic simulations were carried out to select two compounds as possible inhibitors. According to the binding energy, possible ligand localization is in a cavity, close to dimerization interface. Next, cell-based assays were performed on three cell lines: two with tumor phenotype and over-expression of survivin, and another with normal phenotype and low expression of survivin. One of the selected compounds shows a selectively antitumor effect on panel cell lines suggesting that the compound effect could be correlated with the survivin expression.
RESUMO
Resumen La oftalmomiasis es la infestación ocular por larvas de dípteros. Ha sido descrita en pacientes provenientes de áreas rurales, higiene deficiente o por contacto con animales. Sin embargo, existen reportes esporádicos de esta infestación en áreas urbanas. Presentamos el caso de un varón joven, sin factores de riesgo, proveniente de un área urbana al sur del Perú, que presentó 10 larvas en la conjuntiva ocular. Las larvas fueron identificadas como Oestrus ovis, una mosca que suele infestar ovejas y cabras como parte de su ciclo de vida. Realizamos una breve revisión del tema, resaltando la importancia de identificar adecuadamente la especie causante de la miasis, así como su ciclo de vida.

Objetivo: Valorar las medidas antropométricas Indice de Masa Corportal (IMC), Circunferencia Abdominal (CA) e Indice Cintura - cadena (ICC) como factores predictivos para Prehipertensión Arteial (PREHTA) e Hipertensión Arterial (HTA). Método: Estudio transversal analítico, se evaluó en forma aleatoria al 60 por ciento de los trabajadores administrativos de la Universidad Nacional del Centro del Perú (UNCP) compuesta por 173 individuos la distribución por sexo de 94 varones y 79 mujeres, la edad promedio fue 46,39 (+/- 12.086) años. Se emplearon los criterios del Séptimo Informe del Comité Conjunto de Americano en Prevención, Detección, Evaluación y Tratamiento de la Hipertensión Arterial y de la OMS para determinar HTA y medida antropométricas respectivamente. Resultados: Se determinó que el IMC > 25kg/m no es un factor de riesgo significativo para HTA (p=0,417) pero si para PREHTA (p=0,020) en la población general. El ICC y la CA son significativos para predecir riesgo de PREHTA en varones; mientras que en mujeres solo es significativo el ICC. Se observo que el mejor predictor para el PREHTA en varones, CA> 98 cm. (p=0,004) y mujeres CA>90cm (p=0,043).
