The paper analyzes close corporation involuntary dissolution, and places it in the context of two other shareholders remedies: appraisal rights and damages. It is argued that dissolution is oriented to a renegotiation between the majority and the minority shareholder, recreating the initial conditions of the investment with several limits. Based on this analysis, dissolution is described as a mechanism alternative but not subordinate to appraisal rights, and damages as a complementary remedy that must be made compatible with liquidating distribution.

Determining the governing law of corporations–the lex societatis–is relevant today due to the increase of the international activity of corporations. This law is determined in each State by national conflict rules. In Chile, there are no such rules; however, foreign corporations are recognized and have legal capacity in the country. An extensive interpretation of existing domestic rules on corporations allows to conclude that Chilean law submits them to the law of the State of incorporation, but limited by Chilean peremptory rules and public policy. The lex societatis governs the constitution, structure, internal and external affairs of a corporation. Chilean law needs to adopt conflict rules on corporations to guarantee legal certainty on the law governing their international activity.

This paper reflects on two fundamental questions in relation to Litis pendentia: its basis and its initial time. It is intended to demonstrate, on the one hand, that the ratio nale of Litis pendentia has constitutional protection and, on the other hand, that neither the positive nor the dogmatic grounds that have been invoked to justify the initial time of the lis pendens serve to fully explain the interpretation held so far by the prevailing national juris prudence and doctrine.

             

             

             

Introduction: Psoriasis is a chronic immune‐mediated inflammatory skin disease that affects nearly 1–2% of the population worldwide. Biologic treatment of moderate-to-severe psoriasis has changed the disease management paradigm, allowing for better disease control.Methods: A retrospective observational study including patients with moderate-to-severe psoriasis who were treated for at least 36 weeks with guselkumab. Efficacy was evaluated by estimating the proportion of patients achieving PASI 75, PASI 90 and PASI 100 responses at weeks 16, 24 and 36. The Student t-test for paired samples was used to determine the significant difference in outcome of patients between PASI at baseline and PASI response at weeks 16, 24 and 36.Results: 22 patients were included, 14 women (63.6%), with mean age of 48.7±15.5. Guselkumab treatment decreased mean PASI from 10.3±6 at baseline to 2.4±2 (p=0.003), 1.3±1.8 (p=0.001) and 0.3±0.6 (p=0.001) at 16, 24 and 36 weeks, respectively.Discussion: The first anti-IL23 drug family to join the therapeutic arsenal is guselkumab. The efficacy obtained is higher than that observed in phase III studies for PASI 90 and 100 at week 36. There are some studies that have evaluated the short-term effectiveness of guselkumab in real clinical practice; however, this drug has only recently been marketed, limiting the possibility of as yet longer treatment periods.Conclusions: Guselkumab shows great results in the management of psoriasis in adults. Medium- and long-term real clinical practice will be essential, with a larger sample size and longer follow-up period.

Una de las infecciones virales más comunes -sobretodo en personas de mayor edad- es el Herpes Zóster (HZ). Su característica clínica, hace sospechar al médico de forma temprana, para otorgar un tratamiento adecuado y oportuno. Dentro de las complicaciones más frecuentes se encuentran las sensitivas, sobretodo la neuralgia postherpética.1 Sin embargo, existen un grupo de complicaciones motoras de menor incidencia, como lo es la Pseudohernia abdominal. Ésta corresponde a una paresia segmentaria, que se manifiesta como una protrusión de la pared abdominal sin un defecto real, que aumenta con maniobras de valsalva.1Generalmente se puede presentar en hombres, mayores de 60 años, inmunosuprimidos o con neoplasias hematológicas.1,2,3 El diagnóstico es clínico, aunque se puede confirmar con estudio imagenológico, que evidencie una musculatura de la pared abdominal adelgazada con respecto a la contralateral y que descarta un orificio herniario por un defecto estructural.2 La electromiografía también puede jugar un rol al evidenciar anormalidades en la conducción nerviosa.2 La pseudohernia por HZ tiene un buen pronóstico en la mayoría de los pacientes con recuperación completa entre 2-18 meses.3 Su principal riesgo es la pseudobstrucción intestinal, que se puede manifestar como constipación.2,4 En el siguiente reporte de caso, se analiza a la pseudohernia abdominal como complicación motora infrecuente del HZ y sus características. 

Epidermolysis bullosa is a rare hereditary disorder characterized by skin fragility, recurrent mucocutaneous blisters following minimal trauma, and compromised wound healing. Moreover, some variants have been associated with squamous cell carcinoma. Following, we present the clinical case of a patient with epidermolysis bullosa, who presented a large squamous cell carcinoma of the arm. It was resected using Mohs micrographic surgery, and the final defect was repaired by applying a dermal regeneration template over the wound for a month. After this period, we continued using cures and antibiotic ointment over the wound twice a day, and healing was completed with excellent cosmetic and functional results.  We emphasize, that it is the first medical report where this therapeutic tool is used to support the reconstruction of a surgical defect in a patient with epidermolysis bullosa.

El eritema gyratum repens es una dermatosis muy infrecuente incluida dentro del abanico diagnóstico de las lesiones figuradas. Aparece sobre todo en varones entre la sexta y séptima décadas de vida. Clásicamente se ha relacionado con neoplasias, sobre todo de pulmón, esófago y mama, sin embargo en los últimos años se ha visto que aproximadamente el 30% de los casos no son paraneoplásicos, pudiendo deberse a fármacos, enfermedades reumáticas, manifestaciones atípicas de procesos cutáneos etcétera, e incluso ser idiopáticos, por lo que es importante realizar un adecuado proceso diagnóstico para filiar la etiología, y considerar un amplio diagnóstico diferencial. Presentamos el caso de una mujer de 40 años con lesiones eritematosas anulares concéntricas sugestivas y típicas de eritema gyratum repens, del tipo idiopático tras el correspondiente estudio diagnóstico.
