Battle of the Blocks: Which Pain Management Technique Triumphs in Gender-Affirming Bilateral Mastectomies?

Background: Gender-affirming mastectomy, performed on transgender men and non-binary individuals, frequently leads to considerable postoperative pain. This pain can significantly affect both patient satisfaction and the overall recovery process. The study examines the efficacy of four analgesic techniques pectoral nerve (PECS) 2 block, erector spinae plane (ESP) block, thoracic wall local anesthesia infiltration (TWI), and systemic multimodal analgesia (SMA) in managing perioperative pain, with special consideration for the effects of chronic testosterone therapy on pain thresholds. Methods: A retrospective analysis was conducted on patients aged 18 - 45 who underwent gender-affirming bilateral mastectomies at a New York City community hospital. The study compared intraoperative and post-anesthesia care unit (PACU) opioid consumption, postoperative pain scores, the interval to first rescue analgesia, and total PACU duration among the four analgesic techniques. Results: The study found significant differences in intraoperative and PACU opioid consumption across the groups, with the PECS 2 block group showing the least opioid requirement. The PACU morphine milligram equivalent (MME) consumption was highest in the SMA group. Postoperative pain scores were significantly lower in the PECS and ESP groups at earlier time points post-surgery. However, by postoperative day 2, pain scores did not significantly differ among the groups. Chronic testosterone therapy did not significantly impact intraoperative opioid requirements. Conclusion: The PECS 2 block is superior in reducing overall opioid consumption and providing effective postoperative pain control in gender-affirming mastectomies. The study underscores the importance of tailoring pain management strategies to the unique physiological responses of the transgender and non-binary community. Future research should focus on prospective designs, standardized block techniques, and the complex relationship between hormonal therapy and pain perception.

Condrossarcoma gigante de corpo esternal: relato de caso / Giant chondrosarcoma of the sternal body: case report

Os tumores de parede torácicas são relativamente inusitados, representando 1 a 2% de todas as neoplasias, e cerca de 5% das neoplasias torácicas. Sarcomas são tumores raros e com apresentação heterogênea. São divididos em dois grandes grupos: tumores ósseos e de partes moles. A ocorrência na parede torácica é rara, representando 8% de todos os sarcomas. O tratamento de escolha é a ressecção com margens ampliadas e, quando ocorre a invasão de estruturas profundas, a toracectomia é indicada. A reconstrução do arcabouço ósseo é realizada com materiais de síntese, proporcionando estabilidade, e é seguida da reconstrução de partes moles com retalhos musculares, musculocutâneos ou locais ao acaso. Os tumores malignos primários da parede torácica correspondem a menos de 1% de todas as neoplasias e incluem grande variedade de lesões ósseas e de tecidos moles. Os condrossarcomas representam 20% dos tumores primários da parede torácica, sendo que 80% têm origem nas costelas e 20% no esterno.

Chest wall tumors are relatively uncommon, representing 1 to 2% of all neoplasms, and approximately 5% of thoracic neoplasms. Sarcomas are rare tumors with heterogeneous presentation. They are divided into two large groups: bone and soft tissue tumors. Occurrence in the chest wall is rare, representing 8% of all sarcomas. The treatment of choice is resection with wide margins and, when invasion of deep structures occurs, thoracotomy is indicated. The reconstruction of the bone framework is carried out with synthetic materials, providing stability, and is followed by the reconstruction of soft tissues with muscular, musculocutaneous, or random local flaps. Primary malignant tumors of the chest wall account for less than 1% of all neoplasms and include a wide variety of bone and soft tissue lesions. Chondrosarcomas represent 20% of primary tumors of the chest wall, with 80% originating in the ribs and 20% in the sternum.

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.

Chondrosarcoma of the Sternum: Surgical Challenges, Chest Wall Reconstruction, and Postoperative Management.

Although rare, primary chondrosarcoma is the most frequent malignant tumor of the sternum. It commonly manifests as a painful, expanding mass arising from the costochondrosternal junction. Since it is resistant to radiotherapy and chemotherapy, surgical resection with reconstruction is the preferred treatment. A 50-year-old male presented with swelling over the left fourth sternocostal joint, gradually increasing in size. Imaging and clinical assessment suggested an infiltrative neoplasm, and surgical resection was indicated. The patient underwent a partial sternectomy, including a resection of the xiphoid process and costal cartilages two to seven and a partial resection of the manubrium. Postoperative pathohistological analysis specified the change as a low-grade chondrosarcoma in the pT1 stage. Chest wall reconstruction involved three pectus bars fixated around the ribs and the placement of a synthetic polypropylene mesh. The patient required postoperative rehospitalization due to partial skin layer wound dehiscence, serous drainage, and fever. Empirical antibiotic therapy was initiated, and the patient underwent a median superior laparotomy with partial omentoplasty of the sternal region, preserving the mesh and pectus bars. A culture analysis revealed methicillin-resistant Staphylococcus epidermidis, and postoperative antibiotic therapy was adapted to the antibiogram. Subsequently, all parameters of inflammation decreased, and wound healing followed. A one-year follow-up CT scan showed no disease recurrence. This case highlights the intricate surgical management that contributed to the successful treatment of sternal chondrosarcoma. Sternal wound infection, a severe postoperative complication with a high mortality rate, requires prompt identification, precise revision with culture-directed antibiotics, and effort to preserve the prosthetic material.

Physiotherapy interventions on chest wall mobility in obstructive lung diseases: A systematic review.

PURPOSE: The aim of this systematic review was to investigate the effectiveness of physiotherapy interventions on chest mobility in obstructive lung diseases. METHODS: Searches were performed in PEDro, Pubmed and Cochrane Central Register of Controlled Trials databases without language restrictions between 2010 and 25th December 2020. Randomized controlled trials (RCTs) investigating physiotherapy interventions on chest wall mobility were included. Two independent reviewers screened studies, extracted data, and assessed methodological quality of included studies. The assessment of risk of bias was conducted using the PEDro scale for RCTs. The articles were excluded if they have less than 5 out of 10 score. RESULTS: Five studies included had good to excellent quality. A total of 139 patients were included in all RCTs. Intervention duration ranged from a single session to 12 weeks and the intervention schedules varied, consisting of 1-24 sessions, lasting 5-45 min per sessions. Three studies used respiratory muscle stretching and releasing techniques, one study combined respiratory muscle stretching with aerobic training, and one study planned diaphragmatic breathing. Four studies assessed chest wall mobility with optoelectronic plethysmography, whereas one study used measuring tape. CONCLUSIONS: The result of this first systematic review that investigates the effects of physiotherapy interventions on chest wall mobility in obstructive lung diseases suggests that more and better quality RCTs with objective measurement tools are required.

Discovery of an Anteriorly Deviated, Partially Ossified Xiphoid Process With a Large, Teardrop-Shaped Foramen in a Male Cadaver.

The sternum, or "breastbone," is a principal bony component of the anterior thoracic wall and comprises the manubrium of the sternum, the body of the sternum, and the xiphoid process. The xiphoid process is the most inferior of these elements and commonly presents as a small, solid bone shaped like an inverted triangle. However, clinical literature has reported numerous variations in its size, shape, and presentation, likely the result of its lengthy embryological development from cartilage into fully ossified bone. In this case report, a rare, anteriorly deviated, partially ossified xiphoid process with a large, teardrop-shaped foramen is presented that was discovered during a routine cadaveric dissection of a 75-year-old male within an undergraduate anatomy course. Although anatomical variations in the xiphoid process are often asymptomatic and often only found incidentally through CT or X-ray scans, healthcare professionals should be aware of such variations to avoid both misdiagnoses as well as iatrogenic complications.

Bilateral Sternalis Muscles: The Clinical Significance of This Rare Discovery.

This case report explores the physical characteristics and clinical significance of the sternalis muscle, an uncommon anatomical variation of the anterior thoracic wall. If present, the sternalis muscle may distort diagnostic images and can be associated with incorrect interpretation of such medical images, misdiagnoses, and even surgical complications. As such, enhancing clinicians' knowledge of this muscle and improving its recognition is of the utmost importance. In this case report, a rare bilateral sternalis muscle that was discovered during an educational human cadaveric dissection of a 73-year-old Black male is described. The right sternalis muscle fibres extended from the mid-sternal level to the right sternocostal arch, measuring 11.5 cm in length and 3.4 cm at its largest width. In contrast, the smaller left sternalis muscle fibres measured only 5.6 cm in length and 1.2 cm at its greatest width. This rare bilateral presentation of the sternalis muscle is documented in approximately one-third of all reported sternalis cases with an associated estimated prevalence as low as 1.7% among the general population. Serving as a reminder of the intricate anatomical complexities that continue to challenge and intrigue medical professionals, this report advocates for continued education of anatomical variations to enhance patient care and medical practices.

Tuberculosis of the Scapula, Humerus, and Postero-Lateral Thoracic Wall Without Pulmonary Involvement Mimicking Ewing's Sarcoma: A Report of a Rare Case.

Tuberculosis can present in various atypical forms. The clinical manifestations could involve sites like bones. Tuberculosis of the scapula, humerus, and posterolateral thoracic wall is extremely rare, and diagnosis is challenging due to similarities with conditions like tumors. A young boy presented with swelling of the right shoulder joint for three months. The diagnosis was challenging due to similarities with Ewing's sarcoma on the initial radiometric workup. A clinical assessment and diagnostic workup with biopsy, a cartridge-based nucleic acid amplification test, and an advanced radiometric investigation resulted in a final diagnosis. He was started on antituberculous drugs for 12 months.

A new custom-made bivalve brace for pectus carinatum in children and adolescents: preliminary promising experience of 140 patients from a tertiary center.

Introduction: International research suggests that poor patient compliance is the main cause of tutor failures in the context of potential novel orthopedic bivalve braces for conservative treatment of pectus carinatum. Our entire experimental study is based on the hypothesis that a rigid bivalve brace that patients can accept could solve the main problem associated with the conservative approach-poor compliance. The hypothesis was to reduce the thickness and weight of the classic bivalve brace to ensure concealment and make it sustainable enough to be worn several hours a day without compromising its therapeutic efficacy. Materials and method: The research was conducted from January 2020 to December 2022 to ensure follow-up of all participants for at least 6 months. In 36 months, 140 patients with pectus carinatum were assessed and conservatively treated with the studied guardian to analyze the therapeutic efficacy of the bivalve brace and patient compliance. From the initial visit, the parents and patient were informed that this is a 2-year therapeutic course during which the bivalve brace should be worn at least 23 h a day (with 1 h of abstinence per day for routine personal hygiene practices). Compliance is the key to therapy success, and the duration of treatment depends on patient adherence. Results: The exceptional effectiveness of the experimental brace was confirmed by both the questionnaire from the patients (with an average satisfaction rate of 8.9/10) and an assessment of the therapy's results by a properly selected medical committee (with a VAS scale satisfaction of 7.2/10 for symmetric forms and 7.1/10 for asymmetric ones). Conclusion: In conclusion, the analyzed data confirmed the research hypotheses. First, none of the 140 patients had cardiovascular diseases directly related to their condition, confirming that pectus carinatum is a pathology of a purely aesthetic nature. Second, a cheap, lightweight, and easily obscured brace significantly improved patient compliance. Along with this, the social relevance of the aesthetic aspect today may be an important factor in motivating the study cohort to adhere to therapy. In the past, esthetics and appearance were less relevant at the social level, which may have contributed to the high abandonment and reduced compliance rates of the many studies in the literature.

Management of complications after chest wall resection and reconstruction: a narrative review.

Background and Objective: Chest wall resection and reconstruction procedures carry high postoperative morbidity. Therefore, successful outcomes necessitate prevention, prompt identification, and appropriate management of ensuing complications. This narrative review aims to provide a comprehensive overview of evidence-based strategies for managing complications following chest wall resection and reconstruction. Methods: A literature search was conducted using the PubMed database for relevant English-language studies published since 1980. Key Content and Findings: Complications following chest wall resection and reconstruction can be broadly classified into surgical site-related, respiratory, or other systemic complications. Surgical site and respiratory complications are the most common, with reported incidence rates of approximately 40% across some series. Predisposing factors for respiratory morbidity include greater numbers of resected ribs and concurrent pulmonary lobectomy. Definitive correlations between specific prosthetic materials and complications remain elusive. Management should be tailored to the type and severity of the complication, surgical variables, and patient factors. Specific approaches for managing common complications are discussed in detail. Emerging preventive approaches, such as minimally invasive surgical techniques, are also briefly highlighted to help guide future research. Conclusions: An emphasis on anticipating and judiciously managing complications of chest wall resection and reconstruction, alongside a coordinated multidisciplinary approach, can optimize outcomes for patients undergoing this intrinsically complex surgery.

Completeness of Resection and Long-Term Survival of Patients Undergoing Resection for Pathologic T3 NSCLC: An International Association for the Study of Lung Cancer Analysis.

INTRODUCTION: Currently, tumors with different histopathologic characteristics and oncologic outcomes comprise the T3 category of the eight edition TNM classification for lung cancers. To better understand the T3 category, we evaluated completeness of resection and long-term survival in patients undergoing resection for T3 NSCLC. METHODS: The International Association for the Study of Lung Cancer 1999 to 2010 database was queried for patients with pathologic T3N0M0 NSCLC who underwent lobectomy or pneumonectomy. The primary outcome evaluated was overall survival (OS) stratified by T3 descriptors and completeness of resection. RESULTS: Of 1448 patients with T3N0M0 tumors, 1187 (82.0%) had a single descriptor defining them as T3. T3 tumors with chest wall infiltration (CWI) or parietal pleura infiltration (PL3) had the highest rates of incomplete resection (9.8% and 8.4%, respectively), and those classified as T3 by size only had the lowest rate of incomplete resection (2.9%). Individual T3 descriptors were associated with significant differences in OS (p = 0.005). When tumors with similar survival and complete resection rates were grouped, patients with T3 tumors characterized by size or the presence of a separate nodule (SN) in the same lobe had better 5-year OS than patients with tumors characterized by PL3 or CWI (size/SN 60% versus CWI/PL3 53%, p = 0.017) independent of completeness of resection. CONCLUSIONS: Significant differences in 5-year OS were associated with size, SN, PL3, or CWI T3 descriptors. Subdividing pathologic T3N0M0 tumors according to the presence or absence of CWI or PL3 may increase the prognostic accuracy of tumor staging.

Utilizing the visual analogue scale (VAS) to monitor and manage pain in post-operative skin wounds after thoracic surgery.

Due to the global increase in thoracic interventions, there is greater emphasis on refining post-operative care. The purpose of this study was to validate the visual analogue scale (VAS) as the valid method for measuring post-operative pain in thoracic surgery patients. From January 2020 to June 2022, this cross-sectional study investigated 240 adult patients who underwent elective thoracic surgeries in Thoracic Surgery Department of Heilongjiang Provincial Hospital. The participants were instructed to rate their discomfort using VAS at predetermined intervals after surgery. The following demographic and clinical information was recorded: age, gender, type of thoracic surgery, and history of chronic pain. Results showed a progressive decline in post-operative VAS scores over 72 h: 8.2 immediately after surgery, 6.0 at 24 h, 5.4 at 48 h, and 3.6 by 72 h. There were notable correlations between VAS scores and chronic pain history, with moderately positive correlation of 0.40 being observed. Mean scores for males and females were 3.8 and 3.9, respectively. The analysis by age revealed comparable mean scores for age categories below and above 40. With the exception of thoracic wall resection, which resulted in an average VAS score of 4.1 ± 1.0 (p < 0.05), the type of surgery had the minimal effect on variability of pain scores. The VAS is a reliable method for evaluating post-thoracic surgery discomfort. Given the substantial impact of pain history on VAS scores, there is an urgent need for personalized pain management strategies to improve post-operative care.

[Perioperative pain therapy in minimally invasive thoracic surgery]. / Perioperative Schmerztherapie bei minimal-invasiver Thoraxchirurgie.

Thoracic surgery is often associated with severe postoperative pain levels. Even though these are less pronounced in thoracoscopic approaches, mechanical irritation, compression or injury of intercostal nerves and placement of chest tubes can cause pain levels, which must be treated. An adequate pain therapy in thoracic surgery is essential as insufficient inspiration due to inadequate analgesia may result in postoperative complications. Epidural anesthesia was considered the gold standard in thoracotomy for a long time. For video-assisted thoracoscopy, however, it is sometimes no longer recommended due to its benefit-risk ratio. Alternative thoracic blocks are the paravertebral block, the erector spinae plane block and the serratus anterior block, for which research has found heterogeneous results.This article summarizes the current recommendations for perioperative management of thoracoscopic surgery and gives an overview of the PROSPECT recommendations as well as the current Association of the Scientific Medical Societies in Germany (AWMF) guidelines for perioperative and postoperative pain therapy. In particular, individual regional anesthesia techniques and their current evidence are reviewed.

Blockade of intercostobrachial nerve by an erector spinae plane block at T2 level: a case report.

BACKGROUND: The intercostobrachial nerve blockade is required, in addition to brachial plexus block, to anesthetize the entire upper arm. No studies have described the use of erector spinae plane (ESP) block for an intercostobrachial nerve block. CASE PRESENTATION: A 72-year-old man was scheduled to undergo left brachial vein transposition-arteriovenous fistula creation for hemodialysis access. An ultrasound-guided infraclavicular brachial plexus block was performed using a mixture of 0.5% levobupivacaine (12.5 ml) and 2% lidocaine (12.5 ml). An ESP block was implemented using 10 ml of the same local anesthetic at the T2 level. A pinprick test showed that the entire upper arm and lateral aspect of the left upper chest wall were anesthetized 20 min after the blocks. Surgery was successfully performed without the need for general anesthesia. CONCLUSIONS: In the present case, an ESP block performed at the T2 level provided sensory loss of the area innervated by the intercostobrachial nerve.

Multiple Lung Cavity Lesions, Thoracic Wall Abscess and Vertebral Destruction Caused by Streptococcus constellatus Infection: A Case Report.

Disseminated infection caused by Streptococcus constellatus was seldom occurred. We reported a case of Streptococcus constellatus infection, presenting as multiple pulmonary cavities, thoracic wall abscess and vertebral destruction. The 37-year-old male had recurrent fever, chest wall swelling and pain, and lower limb numbness, he had weak physical condition and previously suffered from poorly controlled diabetes and severe periodontal disease for 3 years. Definite diagnosis of Streptococcus constellatus infection was made by metagenomic next­generation sequencing (mNGS) in abscess drainage fluid. Systemic antibiotics and thoracic wall drainage were given, and the pulmonary cavity and the thoracic intermuscular abscess were significantly decreased. Few to no study reported the disseminated infection (pulmonary cavities, thoracic wall abscess and vertebral destruction) caused by Streptococcus constellatus. This case report highlighted the importance of mNGS for accurate diagnosis, as well as the timely drainage and antibiotics for effective treatment of Streptococcus constellatus infection.

Case Report Of Rib Polyostotic Fibrous Dysplasia.

Polyostotic fibrous dysplasia is a rare benign asymptomatic tumour of the ribs not requiring surgery on most occasions. We present here a case with left 10th and 11th rib fibrous dysplasia which was causing a hinderance to the Urologist for renalstone extraction. Therefore the 10th and 11th ribs were excised followed by chest wall reconstruction.

Adaptation And Use of the Papworth Haemostasis Checklist - Clinical Outcomes Analysis at Hospital Estadual Mário Covas.

INTRODUCTION: Postoperative bleeding is one of the main causes of complications in cardiovascular surgery, which highlights the importance of ensuring adequate intraoperative hemostasis, providing a better patient outcome. This study aimed to improve the prevention of postoperative bleeding in the Cardiovascular Surgery Department of the Hospital Estadual Mário Covas (Santo André, Brazil) using an adapted version of the Papworth Haemostasis Checklist to assess the impact of this standardization on bleeding rate, postoperative complications, reoperation, and mortality. METHODS: This is a non-randomized controlled clinical trial, whose non-probabilistic sample consisted of patients undergoing cardiac surgery in the abovementioned service within a two-year interval. The Papworth Haemostasis Checklist was adapted to the Brazilian laboratory parameters and the questions were translated into Portuguese. This checklist was used before the surgeon started the chest wall closure. Patients were followed up until 30 days after surgery. A P-value < 0.05 was considered statistically relevant. RESULTS: This study included 200 patients. After the checklist, a reduction in 24-hour drain output, postoperative complications, and reoperation was observed, although statistical significance was not reached. Finally, there was a significant reduction in the number of deaths (8 vs. 2; P=0.05). CONCLUSION: The use of the adapted checklist in our hospital proved to be an effective intervention to improve the prevention of postoperative bleeding, with a direct impact in the number of deaths in the study period. The reduction in deaths was possible thanks to the reduction in the bleeding rate, postoperative complications, and reoperations for bleeding.
