Case Report: Double Pectus Up in severe pectus excavatum, the new frontier of modified taulinoplasty.

Introduction: Pectus excavatum, also known as "sunken chest" or "funnel chest," is a congenital condition where the sternum caves inward, creating a noticeable depression in the chest. This deformity can range from mild to severe cases, and can affect appearance and lung and heart function. Treatment options vary depending on the severity of the condition and associated symptoms. A case study was conducted on three patients suffering from severe forms of pectus excavatum using modified taulinoplasty with two Pectus Up bars. Case description: The patients were males, with an age of 15 years. Preoperatively, they underwent spirometry, an echocardiogram, and allergy tests. The procedure involved inserting two Pectus Up bars into the chest wall at the major sternal defect, allowing the implant to remain completely invisible. The procedure involved placing the sternal plate at the deepest point and anchored to the sternum with five self-tapping screws. The chest plate was then fixed to the bar using two screws. Discussion: The use of Pectus Up was first reported in 2016 and has been a subject of scientific discussion and research. The double Pectus Up technique offers improved correction, increased stability, and reduced complications. However, it also presents challenges such as increased technical complexity and potential for prolonged operative times. Patient outcomes showed promising results in terms of short-term correction and long-term stability. The use of a double bar technique in the modified Taulinoplasty procedure is a key area of ongoing clinical research and innovation in pectus excavatum repair. Further studies will be needed, including more institutions that use this technique to validate our initial experience.

Case Report: The acute appendicitis and incarcerated umbilical hernia: a rare association.

Introduction: One of the most prevalent congenital wall abnormalities in children, umbilical hernias are often linked to premature or small-for-gestational-age babies. In cases of intestinal malrotation or if the cecum is very movable, generalized peritonitis may facilitate the imprisonment of these hernias. Case report: We described a case of a 4-month-old baby who had a prior reducible umbilical hernia with a history of fever, vomiting, poor appetite, and constipation for around 48 h. The patient experienced significant intestinal bloating, vomiting, irreducibility of the umbilical hernia, skin pigmentation, and erythema at the umbilical site within 2 days after hospitalization. When there was no free abdominal air, a direct abdominal x-ray revealed evidence of hydro-gas stasis and various hydro-aerial levels that were pertinent to the ileum. In order to reduce the hernia, the patient had an emergency surgical treatment where the hernia sac was isolated and released from the ileal loop, which was securely attached to a fibrin plate. When the herniary sac was opened, a gangrenous and perforated appendix was found inside. On the seventh postoperative day, the patient was released from the hospital after an uncomplicated postoperative stay. Conclusion: Our patient's clinical presentation is similar to that of only one other case report involving a 25-day-old male patient. Our case presented with a variant of the clinical symptoms of the previously described umbilical hernia, which became unfixable and strangulated as a result of appendix inflammation. The appendix was discovered inside the hernia sac during surgery.

The role of intraoperative neuromonitoring in preventing lesions of the spinal accessory nerve during functional neck dissection.

Intraoperative neuromonitoring (IONM) in thyroid surgery offers a valid aid to the operator in identifying the recurrent laryngeal nerve and preserving its function. Recently, IONM has also been used in other surgeries, such as spinal accessory nerve dissection, during lymphectomy of the II, III, IV, and V laterocervical lymph nodes. The goal is the preservation of the spinal accessory nerve, whose macroscopic integrity does not always indicate its functionality. A further difficulty is the anatomical variability of its course at the cervical level. The aim of our study is to assess whether the use of the IONM helps to reduce the incidence of transient and permanent paralysis of the spinal accessory nerve, compared to "de visu" identification by the surgeon alone. In our case series, the use of the IONM reduced the incidence of transient paralysis, and no permanent paralysis was recorded. In addition, if the IONM registers a reduction in nerve potential, compared to the baseline value during surgery, it could indicate the need for early rehabilitation treatment, increasing the patients' chances of regaining function and reducing the costs of prolonged physiotherapy treatment.

Comparison of Effectiveness, Feasibility, Indications, and Limitations of Different Intraoperative Dyes in Spinal Neuro-Oncologic Surgery. A Systematic Review.

BACKGROUND: Intramedullary spinal cord tumors (IMSCTs) are rare neoplasms and their management involves tumors resection in most cases. Regarding the surgical procedure, adequate identification of tumor boundaries is paramount to achieve an extensive tumor resection. Fluorescence image-guided surgery (FIGS) has become an increasing popular intraoperative technique used in spine neuro-oncology surgery. However, evidence is lacking of their usefulness and their safety in spinal tumors. Therefore, the aim of the present study is to give an update of the existing literature and systematically review all studies that focus on the most-used fluorophores (5 aminolevulinic acid [5-ALA], sodium fluorescein, and indocyanine green [ICG]) in IMSCTs. METHODS: Using PubMed and Scopus, we performed a systematic review in accordance with the PRISMA protocol and screened all original studies involving humans treated for neurosurgical conditions and studies evaluating FIGS application in IMSCTs. RESULTS: After the screening phase, 27 articles were found to be relevant. The literature results were grouped according to the used fluorophores, resulting in 3 groups: 5-ALA (10 studies); fluorescein (5 studies), and ICG (12 studies). CONCLUSIONS: In intramedullary tumor surgery, 5-ALA has shown its usefulness in identifying the tumor margins and in searching for residues because of its properties as a tumor-specific metabolic marker. Sodium fluorescein and ICG video angiography have shown promising application in ependymoma and hemangioblastomas surgery, respectively. However, the evolving role of fluorescent dyes in guiding surgical strategies in intramedullary spinal tumor has yet to be shown by randomized clinical trials.
