Luxación del núcleo de polietileno acetabular en protesis total de cadera Dislocation of the polyethylene cup in total replacement

Juan J. Panisello Alessandra Martin A. González Agudo F. Lecina Galve G. Clavero

Resumen. El desmontaje del nucleo de polietileno en protesis modulares de cadera es una complicacion rara, generalmente atribuible a malposicion de los implantes o accidentes sobre la cadera proteizada. Se presenta un caso en el que se produjo este accidente sobre implantes bien orientados, atribuible a un intento excesivo de recuperar movilidad sobre una cadera previamente rigida y con retraccion residual de partes blandas. Summary. Disassembly of polyethylene cup in modular hip prostheses is an uncommon complication usually due to malposition of the implants, or accidents on the prosthetic hip. We report a case showing this complication, having the implants in correct position. The cause of dislocation was thrught to be an stressing passive mobilization on a hip with residual retrated soft tissues.

Fractura de Bennet con luxación metacarpofalángica del pulgar asociada Associated Bennett's fracture and metacarpophalangeal dislocation of the thumb

Alessandra Martin Jorge Cuenca Espiérrez Adolfo Rodrı́guez L. Pérez Serrano

Summary. We report a rare case of simultaneous Bennetts fracture and metacarpophalangeal open volar dislocation of the thumb. The Bennetts fracture was treated by percu- taneous pinning. The open volar dislocation was reduced and the collateral ligaments, the extensor tendons, and the dorsal capsule, were surgically repaired. An infection of the metacarpophalangeal joint appeared four weeks later, which was treated by surgical drainage and antibiotic the- rapy. The resultant damage of this joint was treated by arth- rodesis with an external fixator.

Regenerative Surgery in the Treatment of Cosmetic Defect Following Nuss Procedure

Journal of Laparoendoscopic & Advanced Surgical Techniques (2017)

Flavio Facchini Marco Ghionzoli Alessandra Martin Sara Tanini Sara Ugolini

In the past decade, the minimally invasive repair of pectus excavatum (MIRPE) has become the treatment of choice for severe pectus excavatum (PE), proving acceptable to excellent cosmetic results. Recently, autologous fat grafting (FG) has been identified in aesthetic and reconstructive surgery to ideally handle volume and contour defects. We report our experience about FG in the treatment of residual minor defects after MIRPE and a proposal for a new indication of this largely adopted technique.From April 2012 to April 2015, 127 patients underwent bar removal. At outpatient check, a questionnaire was adopted to investigate aesthetic outcome prior and after surgery (3 months postoperation); scoring options varied from 4 to 0 [4, excellent; 3, very good; 2, good; 1, acceptable; and 0, unacceptable]. In patients scoring less than "good," we proposed FG at the same operating session of bar removal. The donor areas were the abdomen, trochanteric region, and inner thigh. The tissue was gently collected through a thin cannula, filtrated, and then promptly injected into the defect.Eleven patients (8.8%) have been selected for FG. No complications have been detected during the follow-up period (range 1-36 months). In three cases, we performed further FG procedure to achieve an optimal result. Questionnaire reported an increased mean score from 1.8 to 2.7.In our early experience, FG has provided satisfactory cosmetic results. With the present report we advocate FG as a minimally invasive "tool" to achieve better defect correction after MIRPE. These preliminary results suggest that FG could be a worthwhile resource in treating chest wall malformations.

Cervical Thymic Cyst in Childhood: A Case Report

Fetal and Pediatric Pathology (2014)

Marta Betti Nasim Hanie Hoseini Alessandra Martin Annamaria Buccoliero Antonio Messineo

Cervical thymic cysts are rare cervical masses which usually present in the first decade of life accounting for 0.3% - 1% of all congenital neck masses. Due to its rarity thymic cysts are seldom included in the differential diagnosis of cystic cervical mass and are often mistaken for more common conditions such as branchial cleft cyst or cystic hygroma. Herein we present a case of a 6-year-old girl with a right lateral cervical cystic mass with multiple septae extended from mandibular angle along the neurovascular bundle of the neck which revealed to be a thymic cyst at histopathology.

Autologous Ear Reconstruction and 3D Printing, an Innovative Hybrid Surgical-engineering Reconstructive Approach for Custom-made Ear Models: Our Experience

Plastic & Reconstructive Surgery Global Open (2023)

Francesca Gigola Virginia Carletti Michele Pezzella Alessandra Martin Roberto Lo Piccolo

Background: Microtia is a congenital anomaly of the ear. We present an innovative technique using a 3D personalized framework that could simplify and standardize the sculpting phase, thanks to reverse engineering and additive manufacturing techniques. Methods: Three-dimensional models were realized by T3Ddy, a joint laboratory between the department of industrial engineering and Meyer Children’s Hospital. Data were obtained retrospectively and included patient demographics, primary diagnosis, side of the affected ear, microtia classification, surgical time, length of hospitalization, type of skin approach and framework, complications, aesthetic results, and level of satisfaction using specific questionnaires. Data are reported as median and IQR. Results: A total of 17 children (female gender: four) underwent auricular reconstruction surgery with autologous cartilage in our center, between 2019 and 2022. Median age at surgery was 14 years [interquartile range (IQR), 13–17], and the median hospitalization length was 5 days (IQR, 3–5). Median surgical time was 420 minutes (IQR, 406–452). Complications occurred in four patients out of 19 procedures, with a complication rate of 21%. Aesthetic results were satisfactory in all cases. Conclusions: The three-dimensional models allow for an intuitive and precise approach. Having developed specific models for each component of the framework, we aimed to improve the aesthetic result and simplify the surgical intervention, guaranteeing a standardized yet personalized experience for each patient. The interprofessional partnership is fundamental to achieving this result.

Giant Ovarian Lymphangioma: Case Report and Review of the Literature

Fetal and Pediatric Pathology (2018)

Elisa Pani Alessandra Martin Annamaria Buccoliero Marco Ghionzoli Antonio Messineo

Introduction: Lymphangiomas are benign tumors/malformations, characterized by proliferation of the lymphatic vessels. They may arise anywhere, although the most common localizations are the head–neck region and the axilla. To date, only 21 cases of lymphangioma of the ovary in a 60-year literature survey have been reported. Case report: A 16-year-old female patient with long standing abdominal distension had 40 cm × 15 cm × 29 cm ovarian lymphangioma. Conclusions: Our case highlights that lymphangiomas can occur in the adolescent population and should be added to the differential diagnosis of ovarian masses in this age group.

Multidisciplinary Surgical Approach to a Surviving Infant With Sirenomelia

PEDIATRICS (2006)

Antonio Messineo Marco Innocenti Riccardo Gelli Simone Pancani Roberto Lo Piccolo

Sirenomelia is an extremely complex and rare malformation with different degrees of lower-extremities fusion associated with gastrointestinal, musculoskeletal, vascular, cardiopulmonary, and central nervous system malformations. In the English literature, there are only 5 reports of infants surviving with this condition. In our case, a 2540-g female infant was born with normal vital signs, no facial dysmorphism, and a complete soft tissue fusion of the lower limbs, from perineum to ankles. Radiologic examinations revealed an intestinal atresia and a single pelvic kidney, with a unique ureter, 2 femurs, 2 tibias, 2 fibulas, and 2 feet (simpus dipus). At 7 months of age, a multidisciplinary surgical team achieved complete separation of the lower limbs, with independent vascular and nerve supplies. At the time of this writing, the infant was 28 months old and had a regular growth curve. Many future reconstructive surgeries have been planned to achieve an acceptable quality of life for this infant.

Treatment of Ovarian Lesions in Children and Adolescents: A Retrospective Study of 130 Cases

Pediatric Hematology and Oncology (2013)

Claudio Spinelli Valentina Pucci Silvia Strambi Roberto Lo Piccolo Alessandra Martin

In this study, we analyze the management of ovarian masses in a total of 130 children surgically treated for 137 ovarian lesions (7 bilateral). The most frequent symptoms were chronic (52.3%) and acute (25.4%) abdominal pain. Histological examination revealed 64 (46.7%) functional lesions, 59 (43.1%) benign neoplasms, 5 (3.7%) malignant ones, and 7 (6.6%) torsed normal ovaries. Ovarian torsion occurred in 36 cases (26.27%). A conservative treatment was performed in 81 (59.1%) girls: 61 (75.3%) treated in nonemergency and 20 (24.7%) in emergency surgery; laparoscopic approach in 35 cases (43.2%); and open surgery in 46 (56.8%). The remaining 56 (40.9%) ovarian masses underwent nonconservative surgery: 40 cases (71.4%) nonemergency and 16 (28.6%) emergency; laparoscopy in 20 patients (35.7%); and open surgery in 36 (64.3%). Fertility preservation should be a goal in the surgical treatment. The management of ovarian torsion should include adnexal detorsion and recovery of the ovarian tissue. In case of benign neoplasms, laparoscopic tumorectomy should be the gold standard; in early stage malignant tumors, fertility-sparing surgery with accurate staging is preferred.
