DICER1-mutated rhabdomyosarcoma is a rare, emerging entity with a predilection for the gynecologic and genitourinary tracts. We report here a case of DICER1-mutated rhabdomyosarcoma of the ovary in a 14 years old girl which displayed interspersed mature teratoid glands, neuroectodermal rosettes and immature blastematous-like tubes. Morphologically the sarcomatous component predominated, corresponding to a high grade spindle cell rhabdomyosarcoma with botryoid features. Islets of cartilage were present. The sarcomatous proliferation encased the teratoid glands, forming cambium layer-like arrangements. The sarcoma cells were Myogenin and MYOD1 positive, the neuroectodermal rosettes expressed SALL4 along with cytokeratins and EMA and were negative for Inhibin; immature blastematous-like tubes were negative for SALL4 and Inhibin. Whole RNA- and targeted DNA-sequencing revealed two DICER1 mutations in exon 26: c.5113G>A: p.(Glu1705Lys) and exon 12: c.1642C>T: p.(Gln548X). The sarcomatous component harbored a complex genetic profile while the teratoid component was diploid, none of the above displayed abnormality of 12p. DICER1-mutated sarcomas display pathological features similar to embryonal rhabdomyosarcomas, botryoid type. They also display heterogeneous features combining cartilage foci, teratoid mature glands, immature blastematous-like tubes and/or neuroectodermal components. Molecular testing remains necessary to confirm the diagnosis. Further studies need to clarify the nosology of DICER1-mutated sarcomas and devise specific therapeutic strategies., (© 2023 The Authors.

Background: The current pandemic due to SARS-CoV-2 has caused a high burden on health. Cases and series of invasive aspergillosis associated with COVID-19 patients (CAPA) on mechanical ventilation have been described., Aim: To describe the increase in the positivity of the galactomannan (GM) biomarker during the COVID-19 pandemic in the Fifth Region: Valparaíso., Method: Retrospective descriptive study. The GM results in both broncho-alveolar lavage (BAL) and serum and the BAL cultures that were sent to the Mycology Laboratory of the University of Valparaíso from January to September 2020 were reviewed; then they were compared with the examinations of the same period of 2019., Results: There was a significant increase in GMs carried out in LBA during the pandemic, concentrating mainly between the months of July-September., Conclusions: There was a significant increase in GM carried out in LBA during the pandemic, concentrating mainly between the months of July-September.

During a study of the fungi from a semi-arid region of northern Chile, a novel species of Aspergillus was encountered in the soil from an area where pepper trees ( Schinusmolle ) were growing. Marker genes were sequenced to identify these isolates. The β-tubulin, calmodulin and DNA-dependent RNA polymerase loci all indicated that this was a novel species in Aspergillus section Nidulantes and in the Aspergillus multicolor clade. The new species was studied morphologically and differences between it and the other members of the A. multicolor clade are described. We provide a name and description for these isolates as Aspergillus incahuasiensis sp. nov.

Background: Ringworm are skin and its annexes infections. Trichophyton tonsurans is an emergent anthropophilic fungus that might cause outbreaks., Aim: To describe a ringworm outbreak by T tonsurans in an elementary school in Valparaíso, Chile., Methods: A descriptive study was run between June and August, 2018. Students and his closest relatives in contact with them who were clinically diagnosed with ringworm have been considered a case. Mycological studies of samples had been carried out through morphophysiology tests. Data are shown in numbers and percentages., Results: There were 18 cases, 16 kids (15 from kindergarten) and 2 adults. Attack rate was 68% in kindergarten. Nine cases were boys with average age of 6 years old. For 14 cases their nationality was Chilean and in 1 case Haitian. First case was a Chilean boy, and primary case was a Haitian boy. The most frequent location was face. Ten cases yielded positive cultures for T tonsurans. Most of the patients needed terbinafine treatment after a therapeutic failure performed with clotrimazole., Conclusion: T. tonsurans outbreak ocurred mainly in kindergarten male. The most frequent location was face. Most of the patients needed terbinafine treatment after a therapeutic failure with clotrimazole.

Objective: The aim of our study was to assess the incidence and identify the predictive risk factors of acute kidney injury after cytoreductive surgery and cisplatin-based hyperthermic intra-peritoneal chemotherapy., Methods: This is a retrospective study from two centers evaluating patients with advanced or recurrent ovarian cancer who underwent cytoreductive surgery followed by cisplatin-based hyperthermic intra-peritoneal chemotherapy from January 2007 to December 2013. Patients were classified into two groups according to the occurrence of acute kidney injury, defined as a glomerular filtration rate at post-operative day 7 25% lower than at day 0. We also evaluated acute kidney injury following Risk, Injury, Failure, Lost and End-stage kidney function criteria. Univariate and multivariate analyses were conducted in order to assess the association between different variables and the occurrence of acute kidney injury., Results: Sixty-six patients were included: 29 (44%) underwent first-line treatment and 37 (56%) were treated for recurrent disease. The incidence of post-operative acute kidney injury was 48%. After multivariate analysis, hypertension (OR 18.6; 95% CI 1.9 to 182.3; p=0.012) and low intra-operative diuresis (OR 0.5; 95% CI 0.4 to 0.8; p=0.001) were associated with acute kidney injury., Conclusion: The incidence of acute kidney injury after cytoreductive surgery and cisplatin-based hyperthermic intra-peritoneal chemotherapy was high. Hypertension and low intra-operative diuresis were independent risk factors for this complication. Adequate peri-operative hydration, in order to maintain correct diuresis, could decrease the occurrence of acute kidney injury in patients undergoing cytoreductive surgery plus hyperthermic intra-peritoneal chemotherapy., Competing Interests: Competing interests: None declared., (© IGCS and ESGO 2019.

Introduction: Perineal hernia is a protrusion of intra-abdominal viscera through a defect in the pelvic floor and is a rare but challenging complication after extensive abdominoperineal surgery. There have been small series published after colorectal exenteration, but no cases have been reported after radical cystectomy and urethrectomy., Case Presentation: A 68 years old woman developed an anterior perineal hernia, with no vaginal prolapse, after an anterior exenteration for bladder cancer. A perineal approach with the use of a synthetic polypropylene mesh was chosen to resolve the condition. After 6 months of follow-up, the patient has no symptoms or recurrence of the anterior perineal hernia., Conclusion: To our knowledge, this case is the first report of perineal hernia after radical urethrocystectomy. Although being a case report, this article describes a potential and challenging complication after extensive anterior pelvic surgery, that could increase its incidence in the future. Literature review shows that whether perineal, abdominal or combined approach is chosen, surgery must respect hernia repair principles., Competing Interests: Brigitte Fatton is consultant for Boston Scientific, Astellas and Allergan.

Objective: Intrauterine adhesions (IUAs) are the most common complication after hysteroscopy in patients of reproductive age. Intra-abdominal anti-adhesion gel reduces the incidence of adhesions, but effects on fertility after uterine surgery are not known. The objective of our work was to evaluate the effect of intrauterine anti-adhesion gel on spontaneous fertility after repeated intrauterine surgery with induced experimental synechiae in the rabbit model., Materials and Methods: Twenty New Zealand White rabbits underwent a double uterine curettage 10 days apart and were randomized into two groups. Each rabbit served as its own control: one uterine tube was the treatment group (A), the second uterine tube was the control group (B) to avoid bias through other causes of infertility. Group A received a post curettage intrauterine instillation of anti-adhesion gel whereas group B, the control group, underwent curettage without instillation of the gel. After a recovery period, the rabbits were mated. An abdominal ultrasound performed 21 days after mating allowed us to diagnose pregnancy and quantify the number of viable fetuses., Results: There was a significant difference in total fetuses in favor of group A, with an average of 3.7 (range, 0-9) total fetuses per tube against 2.1 (0-7) in group B (p = .04). The number of viable fetuses shows a trend in favor of group A, with an average of 3.4 (0-7) viable fetuses per tube against 1.9 (0-6) viable fetuses per tube in group B (p = .05)., Conclusion: The use of immediate postoperative anti-adhesion gel improved fertility in an animal model after intrauterine surgery likely to cause uterine synechiae. This experimental model will permit comparison of different anti-adhesion solutions, including assessment of their tolerance and potential mucosal toxicity on embryonic development.

Objective: The aim of this study was to assess the gynecology obstetric residents training on a birth simulator., Materials and Methods: This is a prospective monocentric study, which had included residents at the beginning of their formation and performed on SIMone™, 3B SCIENTIFIC(®) birth simulator. It had included four sessions (supervised by two seniors registrar): two on instrumental extraction (vacuum and forceps) and two on labor monitoring. The two sessions were performed at one month. A theoretical formation was accomplished after the first assessment. Three assessments were performed based on two score scales (extraction and labor monitoring). A free training was allowed at each extraction session., Results: Twelve interns were included in this study. There was a significant scores improvement between first and third session for instrumental extraction (2.4 points on 11 [±1.8] vs. 8 [±0.9]; [P<0.05]) and for labor monitoring (5.2 [±1.4] points on 9 vs. 6.6 [±1.3]; [P<0.05]). Interns considered this training improved their theoretical and practical knowledge for respectively 11 and 12 interns on 12. For 9 interns, a most important debriefing with teachers was desirable., Conclusion: Training on birth simulator allows an improvement of knowledge and skill of gynecology obstetric interns. A structured debriefing should be instituted after the sessions., (Copyright © 2014 Elsevier Masson SAS. All rights reserved.)

Endometriosis concerns 10% of childbearing age women and frequently affects the digestive tract. We report here the case of a 31-year-old patient presenting a severe occlusive syndrome while being treated with GnRH agonist, within the framework of an in vitro fertilization. The surgical treatment will find a deep endometriosis affecting the sigmoid and colorectal junction and leading to a colorectal resection. These endometriosis lesion recurrences during ovarian stimulation or by GnRH flare up effect is rare and often debated. The surgical treatment of the lesions, before the medically assisted procreation, seems to prevent these complications., (Copyright © 2012 Elsevier Masson SAS. All rights reserved.)

Introduction: Sporothrix schenckii complex comprises a group of environmental dimorphic fungi that cause sporotrichosis. In Chile, isolated cases have been reported in humans, though no environmental isolates have been described., Objective: To achieve isolation of Sporothrix complex from the soil where a 75 year old patient with lymphocutaneous sporotrichosis performs horticulture work., Materials and Methods: In March and July 2011 soil and plant debris from five sectors where the patient does his work in horticulture was extracted. The soil samples were diluted and inoculated in Sabouraud agar with cycloheximide and chloramphenicol at 26 °C. The plant debris was directly inoculated in the same medium. Colonies suggestive of Sporothrix complex were reseeded in PDA agar at 26 ° C and identified as recommended by Marimon et al., Results: Of the 10 plates from the first sampling, one colony was identified as Sporothrix globosa. In the second sampling, Sporothrix globosa grew in two plates seeded with soil, with a total of 6 colonies. There was no growth of Sporothrix complex in plant debris. The isolate from the patient was also identified as Sporothrix globosa., Conclusion: For the first time in Chile a species of Sporothrix complex was isolated from the environment. Sporothrix globosa was the species identified both in the ground and from the patient with sporotrichosis.
