A 17-year-old girl presented with bilateral lower limb lymphedema since 3 years. Lymphedema in the right leg was Grade III, not pitting and not reducing in size after limb elevation. She hailed from a tribal community. Considering her young age, a single-stage operative procedure for her lymphedematous leg was followed, as she was not prepared for a multistaged operation. However, this operative procedure needed to be a combination of both, debulking and physiological procedures, so as to give her immediate limb girth reduction as well as reduction in recurrence, as seen with debulking procedures. We report a newer technique that could achieve both goals.

Extrapelvic endometriosis is a rare presentation of endometriosis with atypical clinical symptoms. It can mimic peritoneal surface malignancy, as well as some abdominal infectious diseases. A 29-year-old Moroccan woman presented with abdominal pain, progressive abdominal distention, and an intermittent inflammatory syndrome. Imaging revealed multiple, progressively growing abdominal cysts. She had elevated tumor markers CA125 and CA19.9. Despite thorough investigation, several differential diagnoses persisted for a long time. Definitive pathological diagnosis could only be established after debulking surgery. Literature review on malignant and benign conditions causing multicystic abdominal distention is provided. When definitive diagnosis is not established, but suspicion for peritoneal malignancy remains, a debulking procedure can be undertaken. Organ preservation can be pursued whenever benign disease is still considered. In case of malignancy, short-term (curative) debulking procedure with or without hyperthermic intraperitoneal chemotherapy (HIPEC) can be proposed. [ABSTRACT FROM AUTHOR]

Background: The microvascular free fibula (MFF) flap is a reliable treatment modality for mandibular reconstruction and is suitable for dental implant placement after oncologic surgery. The most common issue with the MFF flap is its limited bone height, which typically results in excessive interarch space and complicates prosthodontic therapy. Overcoming the physical limitations from tumor excision and reducing the treatment time for prosthodontic rehabilitation to improve quality of life are critical clinical challenges. Case Presentation: A 64-year-old male with lower left gum and bilateral buccal cancer received a single-layer microvascular MFF flap to reconstruct a mandibular defect post-tumor excision. He underwent a bilateral modiolus Z-plasty combined with a skin flap debulking procedure to relieve oral contracture, achieving adequate mouth opening for prosthodontic rehabilitation. Scar tissue bands on the bilateral cheeks significantly affected retention and stability, hampering dental impression performance. The patient sought prosthodontic rehabilitation to enhance his chewing function and quality of life promptly. Prosthodontic rehabilitation with all-on-4 implant therapy, utilizing computer-aided design and computer-assisted manufacturing (CAD/CAM), was completed within one month. Conclusion: This case utilized the all-on-4 implant system to address the insufficient fibular height for conventional dental implant placements. Dental CAD/CAM was employed to mill custom prosthetic abutments and a large titanium framework for the implant bar overdenture, compensating for the excessive interarch space between the grafted fibula and maxilla. This treatment approach successfully shortened the prosthodontic rehabilitation time and overcame anatomical limitations. [ABSTRACT FROM AUTHOR]

Background: Primary tumors of the heart are a rare phenomenon. Lymphatic malformations are congenital anomalies of the lymphatic system that tend to grow progressively. Lymphatic malformations are typically found in the cervical and axillary regions and found on pediatric patients. We report a 40-year-old woman with giant epimyocardial lymphatic malformation. Case presentation: A 40-year-old woman was assessed due to suspected traumatic cardiac tamponade. Computed tomography of the heart and cardiac magnetic resonance imaging were compatible with either a large pericardial hemangioma or angiosarcoma. The tumor infiltrated deeply into the myocardium and could only be partially resected. Histopathological diagnosis was a cardiac lymphatic malformation with micro- and macrocystic components. The patient has remained asymptomatic for fourteen years after the surgery. In the latest follow-up, her left ventricular function had remained normal and the maximum thickness of the residual tumor had regressed. Conclusions: Even when a complete removal of a cardiac lymphatic malformation is not possible, a debulking procedure can yield a good long-term result. [ABSTRACT FROM AUTHOR]

Intracavitary pulmonary aspergilloma is a persistent and life-threatening infection that carries a mortality rate of up to 15%. It occurs when Aspergillus species gain entry to an existing lung cavity. In the absence of definitive treatment, patients may succumb to severe complications such as massive hemoptysis, cachexia, or secondary infections. Aspergillomas often show limited response to antifungal medications, mainly due to insufficient drug concentrations within the cavities. Surgery is frequently the preferred treatment option, but it poses significant risks, and many individuals are ineligible due to underlying health issues. We present the most extensive non-surgical fungal ball cohort to date, managed using an innovative multimodal strategy that combines antifungal therapy before and after bronchoscopic debulking. This was a cross-sectional observational study. For those who cannot undergo surgery, our medical center has pioneered a multimodal approach to aspergilloma resection. This approach combines bronchoscopic endoscopy with antifungal therapy and has been applied successfully to more than 18 patients that are presented in this series. The median age of the cohort was 58 years (range: 32–73), with an equal sex distribution. The mean percent predicted FEV1 was 65.3%. The mean follow-up duration was 3.6 years (range: 0.5–10 years). The cohort receiving antifungals systematically prior to debridement showed a reduction of the pre-existing cavity (40.38 mm versus 34.02 mm, p = 0.021). Across the 18 patients during the follow-up period, 94% remained recurrence-free (defined by symptoms and radiology). Our study fills a critical knowledge gap regarding the significance of initiating antifungal treatment before bronchoscopic debulking and presents a viable approach in these cases for which there is a current unmet therapeutic need. Plain Language Summary: The use of both medical and interventional methods to treat difficult fungal masses: A collection of cases showing efficacy for patients who can't undergo surgery Intracavitary pulmonary aspergilloma is a serious and potentially deadly infection with a death rate of up to 15%. It happens when certain types of fungi invade existing lung cavities. Without proper treatment, patients may experience severe complications like heavy bleeding from the lungs, weight loss, or other infections. Traditional antifungal medications often don't work well because they can't reach high enough concentrations in the cavities. Surgery is usually the best option, but it's risky and not possible for many due to other health problems. Our study introduces a new way to treat aspergilloma without surgery. We've treated a significant number of patients using a combination of antifungal drugs and a procedure called bronchoscopic debulking. This involves removing the fungal growth using a thin tube inserted through the airways. Our research involved observing 18 patients treated this way. They were mostly middle-aged, with equal numbers of men and women. Their lung function was moderately impaired, and we followed them for an average of 3.6 years. We found that giving antifungal drugs before the debulking procedure helped reduce the size of the cavities. After treatment, almost all patients remained free of symptoms and signs of recurrence. This study highlights the importance of starting antifungal therapy before bronchoscopic debulking and offers a promising option for patients who can't have surgery. [ABSTRACT FROM AUTHOR]

Summary: Operating theatre fires are rare but can result in significant morbidity. A 76‐year‐old male with complex airway disease sustained superficial facial burns during an elective airway debulking procedure. His airway was being managed with high‐flow nasal oxygen at 70 l.min−1 and FiO2 1.0 delivered by Optiflow™ (Fisher and Paykel Healthcare Limited, Auckland, New Zealand). When suction monopolar diathermy was used to excise hyperkeratotic tissue beside his epiglottis, an arc was created to the tip of the suspension laryngoscope, followed by a jet of flame as the Optiflow circuit ignited. This resulted in burns to the patient's face and shoulder. He required admission to the intensive care unit and had a complicated postoperative course that included the need for surgical tracheostomy to facilitate weaning from mechanical ventilation. This case highlights the dangers of using high‐flow nasal oxygen alongside an ignition source. [ABSTRACT FROM AUTHOR]

Background: Oral tissue morphogenesis is innately determined and genetically controlled by underlying connective tissue. The connective tissue graft (CTG) harvested from palatal donor sites originally retains "regional specificity" and is considered to be responsible for epithelial keratinization. Methods: This case study presents histological and genomic outcomes of coronally advanced flap (CAF) with CTG for the management of marginal tissue recession (MTR). The tissue samples harvested at 12‐month postoperative period, during the debulking procedure of the treated site were subjected to Masson's trichrome staining (MTS) and whole‐genome sequencing (WGS). Results: Clinically, the mean root coverage as compared to baseline at 6 months (90%), 12 months (95%), and 24 months (95%) postoperatively was achieved. Overbulking of treated site was evident even after 12 months. Nevertheless, clinically discernible alterations in epithelial keratinization were not present. Although MTS revealed areas of non‐keratinization and para‐keratinization, WGS revealed a significant expression of keratinization genes, neural crest, and positional marker genes. Conclusions: CAF with CTG is still considered the "gold standard" in treatment of MTR. The keratinization of overlying epithelium at sites hitherto where non‐keratinized mucosa is advanced over CTG may not be complete even after 12 months. It is evident from the analysis of the reported case that clinically such sites may appear non‐keratinized despite the expression of genes for keratinization. The complex interplay between genomic and phenotypic expressions serves as a foundation of biological concepts. Nevertheless, it is imperative to acknowledge that the phenotype of an organism is not solely determined by genetic expression and is often influenced by a complex interaction between genetic background and environmental factors. Key Summary: The connective tissue serves as a medium for transmitting the genetic code and exerting an influence on the properties of the overlying epithelial tissue. Concrete evidence implies connective tissue plays a significant role in influencing the keratinization process of the overlying epithelium.Epithelial keratinization following a coronally advanced flap with connective tissue graft is also governed by environmental factors in addition to inherent potential within the graft.Differences in gene expression profiles may vary from individuals, teeth and among sites.

Introduction: The Buschke–Löwenstein tumor (BLT) is an uncommon sexually transmitted ailment attributed to the human papillomavirus (HPV)—usually the 6 or 11 type (90%)—with male predominance and an overall infection rate of 0.1%. BLT or giant condyloma acuminatum is recognized as a tumor with localized aggressiveness, displaying distinctive features: the potential for destructive growth, benign histology, a rate of 56% malignant transformation, and a high rate of recurrence after surgical excision. There are several treatment choices which have been tried, including laser, cryotherapy, radiotherapy, electrocoagulation, immunotherapy, imiquimode, sincatechins, intralesional injection of 5-fluoruracil (5-FU), isolated perfusion, and local or systemic chemotherapy. In the case of an extensive tumor, preoperative chemotherapy or radiotherapy is used for tumor shrinkage, making the debulking procedure safer. HPV vaccines significantly decrease the incidence of genital warts, also decreasing the risk of BLT; HPV-6 and HPV-11 are included in these vaccines. Materials and methods: We present a 53-year-old heterosexual man, hospitalized in our department in June 2021 with a typical cauliflower-like tumor mass involving the perianal region, which progressively increased in size for almost 7 years. The perianal mass was completely removed, ensuring negative surgical margins. The large perianal skin defect which occurred was reconstructed with fascio-cutaneous V-Y advancement flap. There was no need for protective stoma. The literature review extended from January 1980 and December 2022, utilizing Pubmed and Google Scholar as search platforms. Results: Due to the disease's proximity to the anal verge and the limited number of reported cases, arriving at a definitive and satisfactory treatment strategy becomes challenging. The optimal approach entails thorough surgical removal of the lesion, ensuring well-defined surgical margins and performing a wide excision to minimize the likelihood of recurrence. In order to repair the large wound defects, various rotation or advancement flaps can be used, resulting in reduced recovery time and a diminished likelihood of anal stricture or other complications. Our objective is to emphasize the significance of surgical excision in addressing BLT through the presentation of a case involving a substantial perianal condyloma acuminatum, managed successfully with complete surgical removal and the utilization of a V-Y advancement flap technique. In the present case, after 5 months post operation, the patient came back with a buttock abscess, which was incised and drained. After another 5 months, the patient returned for difficult defecation, with an anal stenosis being diagnosed. An anal dilatation and sphincterotomy were carried out, with good postoperative results. Conclusions: The surgical management of Buschke–Löwenstein tumors needs a multidisciplinary team with specialized expertise. The reconstruction techniques involved can be challenging and may introduce additional complications. We consider aggressive surgery, which incorporates reconstructive procedures, as the standard treatment for Buschke–Löwenstein tumors. This approach aims to achieve optimal surgical outcomes and prevent any recurrence. [ABSTRACT FROM AUTHOR]

Chordomas are rare, malignant bone tumors that arise from embryological remnants of the notochord, typically affecting the skull base, mobile spine, and sacrum with uncommon metastasis to the larynx. Patients with metastasis to the larynx may present with slowly progressive dysphonia and dyspnea. Here, we report an organ-preservation treatment strategy for a patient with widely metastatic extra-axial chordoma presenting with airway compromise who was found to have a new metastasis to the cricoid cartilage.

Background Lower extremity trauma often necessitates reconstruction with flap transfer. One of the reconstructive goals is a thin soft tissue coverage with appropriate contour. Therefore, a secondary debulking of the flap is usually performed. Methods Debulking through conventional lipectomy is compared with liposuction followed by excision of the defatted flap excess. Demographic data, surgical details, and postoperative outcomes are compared and analyzed. The perfusion dynamics of the flaps undergoing liposuction debulking are studied by means of perioperative indocyanine green fluorescence angiography, as well as postoperative laser Doppler imaging. Results Patients undergoing lipectomy (n = 69; 57.5%) or liposuction (n = 51; 42.5%) debulking had a similar rate of postoperative complications. Partial necrosis was observed in 7.2% (lipectomy) versus 7.8% (liposuction) of flaps. Fluorescence angiography showed a substantial decrease in flap perfusion following the infiltration with an epinephrine-containing tumescent solution (74.3% ± 8.2% prior to infiltration versus 16.8% ± 7.1% after infiltration; p < 0.001), resulting in a dark flap appearance. Laser Doppler imaging confirmed the hypoperfusion on postoperative day 1. Conclusion Secondary debulking of a lower extremity flap can be safely and efficiently performed through liposuction combined with peripheral excision of the defatted flap in a single stage. Perfusion studies may show a misleading hypoperfusion of the defatted flap, which does not accurately predict subsequent necrosis or complications. [ABSTRACT FROM AUTHOR]

Macrodactyly of the toe is a rare congenital anomaly characterized by the overgrowth of a digit/digits in the foot and is one of the most difficult conditions to treat. Since the condition alters functionality and appearance, the treatment goal is to restore function and cosmetically enhance the appearance. Various surgical techniques are used for toe macrodactyly, including amputation, debulking, and epiphysiodesis. Herein, we present a case of a six-year-old patient with a second toe macrodactyly who was successfully treated with a two-stage operation over a seven-year period. We initially performed an ostectomy of the middle phalanx with a fusion of the proximal and distal phalanges and then performed a soft tissue debulking procedure. [ABSTRACT FROM AUTHOR]

Objective: Liposuction is the most frequently performed debulking procedure in patients with lymphedema. However, it remains uncertain whether liposuction is equally effective for upper extremity lymphedema (UEL) and lower extremity lymphedema (LEL). In this study, we retrospectively compared the effectiveness of liposuction according to whether it was performed for LEL or UEL, and identified factors associated with outcomes. Materials and Methods: All patients had been treated at least once by lymphovenous anastomosis or vascularized lymphatic transplant before liposuction but without sufficient volume reduction. The patients were divided into an LEL group and a UEL group, and then subdivided further according to whether they completed their planned compression therapy into an LEL compliance group, an LEL non-compliance group, a UEL compliance group, and a UEL non-compliance group. The reduction rates in LEL (REL) and in UEL (REU) were compared between the groups. Results: In total, 28 patients with unilateral lymphedema were enrolled (LEL compliance group, n = 12; LEL non-compliance group, n = 6; UEL compliance group, n = 10; UEL non-compliance group, n = 0). The non-compliance rate was significantly higher in the LEL group than in the UEL group (p = 0.04). REU was significantly higher than REL (100.1 ± 37.3% vs. 59.3 ± 49.4%; p = 0.03); however, there was no significant difference between REL in the LEL compliance group (86 ± 31%) and REU in the UEL group (101 ± 37%) (p = 0.32). Conclusion: Liposuction seems to be more effective in UEL than in LEL, probably because the compression therapy required for management after liposuction is easier to implement for UEL. The lower pressure and smaller coverage area required for postoperative management after liposuction in the upper limb may explain why liposuction is more effective in UEL than in LEL.

• Chemotherapy response score is a valuable tool that helps determine patients at risk of earlier relapse and death. • The importance of debulking surgery remains significant even in those with minimal response to chemotherapy. • Survival differences of CRS 1-2 vs CRS 3 patients were similar to those of patients with platinum resistant vs sensitive disease. The chemotherapy response score (CRS) has been widely adopted as a predictive tool for ovarian cancer survival. In the present study, we seek to define differences in survival rates among patients grouped in the traditionally established three-tiered system and those who have not been offered debulking surgery. We designed a retrospective cohort study involving women treated with chemotherapy and offered interval or late debulking surgery for ovarian cancer. Twenty-eight women were not considered for a debulking procedure for various reasons. Of the 89 women who were finally offered interval debulking or late debulking surgery, 28 had a CRS 1 score, 34 had a CRS 2 score and 27 had a CRS 3 score. Significant differences were noted in the progression-free survival (PFS) and overall survival (OS) of patients based on the CRS stratification, although survival rates were considerably longer for all three groups compared to those of patients who were not offered surgery. Cox regression univariate analysis revealed that suboptimal debulking and CRS 1 or no surgery had a significant negative impact on PFS and OS rates. The binary stratification of CRS (CRS 1–2 vs CRS 3) revealed comparable differences in the PFS and OS to those in the groups that were stratified as platinum resistant and platinum sensitive. The chemotherapy response score is a significant determinant of ovarian cancer survival that helps evaluate the risk of early disease relapse and death and may soon be useful in guiding patient-tailored treatment.

Chordomas are rare malignant neoplasms, accounting for 1–4% of all primary bone tumors. Most spinal chordomas occur in the sacrococcygeal region and the base of the skull; however, 6% of chordomas are observed in the cervical spine. In these cases, the lesion is mainly located in the midline. These tumors slowly grow before becoming symptomatic and encase the surrounding vascular and nerve structures. Patients with advanced chordoma have a poor prognosis due to local recurrence with infiltration and destruction of adjacent bone and tissues. Systemic chemotherapy options have not been fully effective in these tumors, especially for recurrent chordomas. Thus, new combinations of currently available targeted molecular and biological therapies with radiotherapy have been proposed as potential treatment modalities. Here, the present paper describes the case of a 41-year-old male with a C2–C4 chordoma located paravertebrally, who underwent surgical resection with a debulking procedure for a cervical chordoma. Computed tomography angiography revealed a paraspinal mass with bone remodeling and the MRI showed a paravertebral mass penetrating to the spinal canal with a widening of the intervertebral C2–C3 foramen. Initially, the tumor was diagnosed as schwannoma based on its localization and imaging features; however, the histopathology specimen confirmed the diagnosis of chordoma. This case study highlights the effectivity of radical surgical resection as a mainstay treatment for chordomas, discusses neuroimaging, diagnosis, and the use of currently available targeted therapies and forthcoming treatment strategies, as alternative treatment options for chordoma.

It is difficult to treat large postburn sequelae (scars and defects) over the face. Available methods include skin grafts, local flaps, tissue expansion, and free flaps. These surgical options should be chosen wisely, depending on individual patient requirements and the area involved. In patients with large postburn scars and defects in which the surrounding tissue is also involved, use of free tissue transfer is extremely useful. A retrospective analysis was done between 2011 and 2019 of 52 cases with extensive facial burn deformities in whom secondary reconstruction was done with free parascapular flap cover in our department. Outcome was assessed by a direct questionnaire. There was no complete flap loss in the series. Two cases were re-explored for venous insufficiency and suffered partial marginal necrosis. Twenty patients had to undergo further debulking procedure. Forty-seven patients were satisfied by the final outcome. Postburn facial deformities are difficult to treat; in many cases, there are no local options, and tissue from different regions is to be used for reconstruction. Free parascapular flaps can be used as an effective method in such cases with a high level of patient satisfaction. [ABSTRACT FROM AUTHOR]

A 74-year-old woman with a history of multiple resections and radiotherapy for recurrent sacral chordoma was referred with local recurrence, manifesting as symptoms of lower back pain, constipation and urinary incontinence. Long-term clinical outcomes following en bloc resections for sacral chordomas and chondrosarcomas: a series of twenty consecutive patients. Since this time, she has undergone coccygeal resection, five additional local resections with attempted clear margin, one operative debulking procedure and a course of external beam radiotherapy.

Osteosclerotic metaphyseal dysplasia (OMD) is an extremely rare form of osteopetrosis, which bears significant clinical similarities to dysosteosclerosis (DSS). We aim to present a rare case of OMD with mandibular swelling and osteomyelitis infection including diagnosis journey as well as management in 7-year- old patient. Literature review completed for OMD cases. Case report investigative methods include genetic testing, CT facial bones and MRI scan, orthopantogram and bone biopsies. An initial suspected diagnosis of DSS with chronic osteomyelitis was made. However, following genetic testing, a diagnosis of OMD was confirmed. Our patient underwent a surgical debulking procedure and antibiotic treatment. Less than 10 patients with this condition have been reported within the international literature. There is a wide range of presentation. OMD, DSS and osteomyelitis are all within a similar spectrum of bone conditions. Our understanding, regarding OMD, remains limited and, hence, further research is required to elucidate a thorough clinical picture. [ABSTRACT FROM AUTHOR]

Background: Chordomas are rare benign, but locally aggressive tumors that are regularly encountered in the clivus and sacrum. Although they are rarely found in the thoracic spine, they can contribute not only to local bone destruction and spinal instability, lead to cord compression, and major neurological deficits. Case Description: A 56 year-old-male originally underwent a T12 laminectomy with debulking for a thoracic chordoma. Two years later, the lesion recurred contributing to a significant paraparesis. The new MR showed a T2 hyper intense lesion with huge epidural extension that warranted a 360° surgical decompression and fusion. The histopathology from both surgeries confirmed the diagnosis of a chordoma. Conclusion: Combined 360° decompression and fusion was warranted to resect a T12 chordoma that recurred 2 years following an original laminectomy with debulking procedure. [ABSTRACT FROM AUTHOR]

A 21-year-old male laborer sustained bilateral degloving injury of the hands with multiple digital amputations and devascularized digits. After X-rays, preliminary debridement was done, when digital amputations were completed, including index ray amputation on both sides. The next day, two anterolateral thigh (ALT) flaps and one second toe transfer were done to restore coverage in the palm and the web and reconstruct the lost thumb. This ensured both coverage and thumb length on the right side, but on the left side the procedure was terminated with flap transfer only. After 3 months, the other second toe was harvested with a dorsalis pedis flap for reconstruction of the left thumb, and a free gracilis flap was done for optimal donor site coverage in the donor left foot. Evaluation after 2 years showed functional hands with reasonable power grasp, pinch grip, and dexterity to manipulate small and large objects that permitted an independent living.

Photodynamic therapy (PDT) relies on the interactions between light, photosensitizers, and tissue oxygen to produce cytotoxic reactive oxygen species (ROS), primarily singlet oxygen (1O2) through Type II photochemical reactions, along with superoxide anion radicals (O2•−), hydrogen peroxide (H2O2), and hydroxyl radicals (•OH) through Type I mechanisms. Accurate dosimetry, accounting for all three components, is crucial for predicting and optimizing PDT outcomes. Conventional dosimetry tracks only light fluence rate and photosensitizer concentration, neglecting the role of tissue oxygenation. Reactive oxygen species explicit dosimetry (ROSED) quantifies the reacted oxygen species concentration ([ROS]rx) by explicit measurements of light fluence (rate), photosensitizer concentration, and tissue oxygen concentration. Here we determine tissue oxygenation from non-invasive diffuse correlation spectroscopy (DCS) measurement of tumor blood flow using a conversion factor established preclinically. In this study, we have enrolled 24 pleural PDT patients into the study. Of these patients, we are able to obtain data on 20. Explicit dosimetry of light fluence, Photofrin concentration, and tissue oxygenation concentrations were integrated into the ROSED model to calculate [ROS]rx across multiple sites inside the pleural cavity and among different patients. Large inter- and intra-patient heterogeneities in [ROS]rx were observed, despite identical 60 J/cm2 light doses, with mean [ROS]rx,meas of 0.56 ± 0.26 mM for 13 patients with 21 sites, and [ROS]rx,calc1 of 0.48 ± 0.23 mM for 20 patients with 76 sites. This study presented the first comprehensive analysis of clinical ROSED in pleural mesothelioma patients, providing valuable data on future ROSED based pleural PDT that can potentially produce uniform ROS and thus improve the PDT efficacy for Photofrin-mediated pleural PDT.

Bulkiness is patients' major complaint after free latissimus dorsi (LD) flap. We performed tangential excision debulking at 6–13 days following free LD flap in three patients. No flap necrosis or major complications occurred. Tangential excision debulking during the early phase after free LD flap might be safe and reliable. [ABSTRACT FROM AUTHOR]

Abstract Background The microvascular free fibula (MFF) flap is a reliable treatment modality for mandibular reconstruction and is suitable for dental implant placement after oncologic surgery. The most common issue with the MFF flap is its limited bone height, which typically results in excessive interarch space and complicates prosthodontic therapy. Overcoming the physical limitations from tumor excision and reducing the treatment time for prosthodontic rehabilitation to improve quality of life are critical clinical challenges. Case Presentation A 64-year-old male with lower left gum and bilateral buccal cancer received a single-layer microvascular MFF flap to reconstruct a mandibular defect post-tumor excision. He underwent a bilateral modiolus Z-plasty combined with a skin flap debulking procedure to relieve oral contracture, achieving adequate mouth opening for prosthodontic rehabilitation.

The patient sought prosthodontic rehabilitation to enhance his chewing function and quality of life promptly. Prosthodontic rehabilitation with all-on-4 implant therapy, utilizing computer-aided design and computer-assisted manufacturing (CAD/CAM), was completed within one month. Conclusion This case utilized the all-on-4 implant system to address the insufficient fibular height for conventional dental implant placements. Dental CAD/CAM was employed to mill custom prosthetic abutments and a large titanium framework for the implant bar overdenture, compensating for the excessive interarch space between the grafted fibula and maxilla. This treatment approach successfully shortened the prosthodontic rehabilitation time and overcame anatomical limitations.

Objective: Pseudomyxoma peritonei (PP) is a rare condition, and differentiating between primary and secondary ovarian causes is crucial for determining the appropriate oncological therapy. Given the resistance of ovarian mucinous carcinoma to standard platinum-based chemotherapy, the objective of this review is to present the current therapeutic approaches and summarize the emerging trends in the treatment of this disease. Methods: The authors conducted an exhaustive evaluation of studies published over a 14-year period (June 2010–May 2024) concerning pseudomyxoma peritonei, mucinous ovarian carcinoma, ovarian causes of PP, and ovarian cancer using the following databases: PubMed, Scopus, and Science Direct. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. The results were organized into seven subchapters and analyzed. Results: The analyzed studies present surgery followed by HIPEC as the current therapy with the best long-term survival results. However, the oncological treatment is unsatisfactory, and the choice of therapy depending on the primary origin of the tumor becomes particularly important. For the differential diagnosis between pseudomyxoma due to a gastrointestinal cause and that of ovarian origin, genetic analyses are recommended; these include the characteristics of the mucin present in the lesion, as the therapeutic response can have contradictory results depending on the primary origin of the tumor. Conclusions: Surgery followed by HIPEC remains the standard for resectable cases. However, oncological treatment has controversial results in the case of mucinous ovarian carcinoma compared to other types of ovarian cancer and to metastatic ovarian tumors associated with pseudomyxoma of the peritoneum. Based on the articles included in this review, it was found that the current trend is the study of mucin as a resistance factor against chemotherapy based on platinum products and the targeting of oncological therapy according to the tumor's genetic characteristics.

Background: Approximately 20% of women develop an ovarian cyst or pelvic mass at some point in their lives. Due to high false positivity of CA-125, women with various benign ovarian tumors simulating malignant masses undergo extensive debulking surgery resulting in increased morbidity. Serum HE4 is a useful test for better discrimination of benign or malignant nature of pelvic masses in preoperative period. Our study gives an update on the biological markers specifically CA-125 and a novel tumor marker HE4 and aims to reduce the debulking surgeries done for benign pathology. Materials and Methods: The total study population (n = 302) included women who were operated with suspicious ovarian malignant mass (n = 238) with benign (n = 98), borderline (n = 6), and malignant (n = 134) ovarian tumors. Cutoff of CA-125 was 35 U/mL, and for HE4 140 pM for postmenopausal and 70 pM for premenopausal women were calculated at 86% and 81% accuracy, respectively. Statistical analysis was done using SPSS version 20. Results: The cutoff values of CA-125 were able to differentiate between benign, borderline, and malignant tumors with statistical significance (p < 0.05), whereas the cutoff values of HE4 significantly (p < 0.05) differentiated benign tumors from the malignant tumors, but not from the borderline tumors. Serum CA-125 has significantly higher sensitivity and NPV (95%, 72%, respectively) compared to HE4 (81%, 52%) and combined HE4 plus CA-125 (84%, 59%), whereas specificity, PPV, and AUC were higher for combined CA-125 plus HE4 (93%, 98%, 90%, respectively) compared to HE4 (83%, 95%, 88%) and CA-125 (48%, 88%, 87%). Conclusion: Measuring serum HE4 along with CA-125 in preoperative diagnosis helps in excluding benign ovarian tumors in which CA-125 was falsely raised, especially in center where frozen section is not available, thus potentially decreasing morbid debulking surgeries done for benign ovarian tumors.

Purpose: The purpose of this study is to retrospect and summarize clinical efficiency and experience of the free superficial palmar branch of radial artery (SPBRA) flap for soft-tissue reconstruction in distal digital injury. Method: 13 patients with soft-tissue defect of finger, reconstructed by the free superficial palmar branch of radial artery (SPBRA) flap in our department from January 2020 to January 2022, were reviewed. After 6–12 months of follow-up, evaluated the treatment effect of the fingers reconstructed by SPBRA flap. Results: All the flaps in our series application were survival uneventful, and all the donor sites were closed primarily without complications or obvious scarring. The flaps were soft in texture and satisfactory in appearance and function. The flaps with the median nerve palmar cutaneous branch had a good sensation recovery. Measurement of two-point discrimination (TPD) ranged from 6 to 10 mm. All patients were satisfied with the aesthetic appearance. According to the Evaluation Trial Standards of Upper Limb Partial Function of Hand Surgery of Chinese Medical Association, the results were graded as excellent in 11 cases and good in 2 cases. Conclusion: The SPBRA perforator flap has the advantages of simple operation, soft texture, good appearance and function, and is credible and useful for reconstructing various finger injuries.

Introduction: Ovarian cancer is the third most common gynaecological cancer and has a very high mortality rate. The cornerstone of treatment is complete debulking surgery plus chemotherapy. Even with treatment, 80% of patients have a recurrence. Circulating tumour DNA (ctDNA) has been shown to be useful in the control and follow-up of some tumours. It could be an option to define complete cytoreduction and for the early diagnosis of recurrence. Objective: We aimed to demonstrate the usefulness of ctDNA and cell-free DNA (cfDNA) as a marker of complete cytoreduction and during follow-up in patients with advanced ovarian cancer. Material and Methods: We selected 22 women diagnosed with advanced high-grade serous ovarian cancer, of which only 4 had complete records. We detected cfDNA by polymerase chain reaction (PCR), presented as ng/mL, and detected ctDNA with droplet digital PCR (ddPCR). We calculated Pearson correlation coefficients to evaluate correlations among cfDNA, ctDNA, and cancer antigen 125 (CA125), a biomarker. Results: The results obtained in the evaluation of cfDNA and ctDNA and their correlation with tumour markers and the radiology of patients with complete follow-up show disease progression during the disease, stable disease, or signs of recurrence. cfDNA and ctDNA correlated significantly with CA125. Following cfDNA and ctDNA over time indicated a recurrence several months earlier than computed tomography and CA125 changes. Conclusion: An analysis of cfDNA and ctDNA offers a non-invasive clinical tool for monitoring the primary tumour to establish a complete cytoreduction and to diagnose recurrence early.

Primary colorectal signet-ring-cell carcinoma of the colon and rectum (PSRCCR) is an extremely rare subtype of mucinous adenocarcinoma with a reported rate of less than 1%. This low rate is mainly because it is generally diagnosed at advanced stages. The most common stage at which it is diagnosed for the first time is III or IV, with a lower median survival than other histological subtypes. To diagnose PSRCCR of the colon, at least half of the tumor must be consistent with a signet-ring-cell pattern. This review aims to provide a comprehensive overview of PSRCCR by synthesizing the existing literature and clinical data. Our objective was to elucidate the clinical features, diagnostic challenges, histopathological characteristics, molecular alterations, treatment modalities, and prognostic factors associated with this carcinoma. Additionally, we highlighted the significance of early detection, accurate diagnosis, and personalized therapeutic approaches in improving outcomes for patients with this challenging malignancy. By presenting a case report on the topic, we aimed to enhance understanding among clinicians, pathologists, and researchers, ultimately contributing to optimized management strategies and improved patient care for PSRCCR.

We present a 70-year-old gentleman with chronic cough with haemoptysis found to have left lower zone collapse on imaging. The bronchoscopy showed an endobronchial mass histologically of a non-secreting atypical carcinoid. Poor baseline lung function excluded surgical resection, and instead, he successfully underwent a bronchoscopic debulking procedure which improved his FEV1 to 84% and DLCO 83% predicted. Unfortunately, the tumour regrew, but the calculated percentage predicted postoperative for FEV1 (64%), and DLCO (65%) enabled definitive surgical resection to take place. Surgical resection remains the definite curative option for localised endobronchial atypical carcinoid tumours. Achieving this in proximal endobronchial carcinoid tumour is a challenge. We described an endoscopic tumour debulking procedure as a bridge for curative surgical resection in a patient with an inoperable proximal atypical carcinoid tumour due to poor predicted postoperative lung function. We highlighted the need to assess predicted postoperative lung function with functional and quantitative perfusion methods to aid surgical planning. Debulking the tumour by endoscopy can be used as a conduit to curative surgical resection in bronchial carcinoid tumour. The choice of calculating the percentage predicted values by either or both methods must be individualised based on tumour location and the probability of converting a lobectomy to a pneumonectomy. This precautionary approach could evaluate the postoperative lung function and morbidity and mortality risk if considering a pneumonectomy. Endoscopic debulking can be a successful bridge to a curative surgical resection aided by comprehensive preoperative lung function tests to predict postoperative lung values

BACKGROUND: Crohn’s disease (CD) is an inflammatory bowel disease that usually manifests in any part of the gastrointestinal tract from the oral cavity to the anus, with well-known extraintestinal presentations such as uveitis, erythema nodosum and arthritis. Rarely, it can also present with metastatic vulvar lesions, a conundrum for the gynecologist and gastroenterologist, owing to its similarity with other granulomatous and dermatological conditions like hidradenitis suppurativa, cellulitis and secondary abscess, making it a diagnostic dilemma. CASE: We present the case of a 24-years-old female, married with bilateral swelling in the vulvar region, insidious in onset, associated with pain, watery discharge, red discolouration of the surrounding skin and mild itching since 5 years that worsened in the past 6 months. She also had pain in multiple joints bilaterally, associated with early morning stiffness since childhood that worsened in the past 2 years and a history of hypothyroidism since 6 years followed by irregular menses since 4 years. She consulted a private clinic and the prescribed medications provided relief. However, her symptoms recurred a year later along with additional presentations of fissures and skin tags that gradually increased in severity. On visiting another hospital, a diagnosis of vulvar CD was confirmed on biopsy. She was started on methotrexate, oral steroids and azathioprine; which she adhered to for 6 months with failure to follow up thereafter. It eventually flared up for which she was referred to our hospital, where a thorough evaluation was done by several relevant departments. Positive biopsy findings showing non-caseating granulomas with giant cells along with positive ANA (Anti-nuclear antibody) and anti-CCP antibody (Anti-cyclic citrullinated peptide) correlated with the clinical symptoms confirmed the diagnosis of CD and rheumatoid arthritis respectively. The debulking procedure was done considering the severity of the lesion and the failure of the medications. Post-operative pathological evaluation of the procured tissue confirmed the pre-operative diagnosis. CONCLUSION: This case underscores the difficulties encountered during the diagnosis of vulvar CD, especially in the absence of any gastrointestinal symptoms and signs on colonoscopy. It also emphasizes the importance of considering the differential of CD when faced with multiple vulvar symptoms. Undoubtedly, biopsy remains the cornerstone of diagnosis; and early diagnosis and treatment significantly is quintessential to improve the quality of life.

Objective: This study aimed to assess the efficacy and safety of bilateral superselective adrenal arterial embolization (SAAE) in patients with bilateral idiopathic hyperaldosteronism (IHA), a subtype of PA. Methods: Ninety-eight patients with bilateral IHA underwent bilateral SAAE between August 2022 and August 2023. Sixty-eight patients were followed up for up to 12 months. The study outcomes were evaluated using the criteria provided by the Primary Aldosteronism Surgical Outcome (PASO) guidelines. Results: The mean reductions in systolic and diastolic blood pressure were 27.4 ± 21.3 mmHg and 23.1 ± 17.4 mmHg, respectively (p < 0.001). The rates of clinical success and biochemical success after adrenal artery ablation were 63.2% (43/68) and 39.7% (27/68), respectively. Overall, there were significant reductions in daily defined doses (DDD), aldosterone/renin ratio (ARR), and plasma aldosterone levels (p < 0.001). Plasma renin levels increased by a mean value of 10.4 ± 39.0 pg/mL (p = 0.049), and potassium levels increased by 0.40 ± 0.63 mmol/L (p < 0.001). No significant adverse events were reported during SAAE or the follow-up period of up to one year. Additionally, no abnormalities were detected by adrenal 68Ga-Pentixafor PET/CT scans before or after SAAE. Conclusion: Bilateral SAAE appears to lead to sustained improvements in blood pressure and biochemical parameters in patients with bilateral PA, with minimal adverse effects. This suggests that bilateral SAAE could serve as an effective alternative approach for treating bilateral IHA, potentially curing this condition. [ABSTRACT FROM AUTHOR]

Background: Surgical dissection and partial detachment of the temporalis muscle during neurosurgical procedures might result in a temporal depression known as "temporal hollowing". Reconstructive procedures to correct this condition include the implantation of synthetic materials (e.g., hydroxyapatite, methacrylate or polyethylene), injection of autologous fat or fillers as well as the use of flaps (e.g., temporo-parietal local flap and latissimus dorsi free flap). However, none of these techniques proved to be an ideal option due to a high complication rate or need for invasive and complex surgery. Adipo-dermal grafts are autologous; the resorption rate seems to be limited and the complexity of the procedure is minor. Moreover, autologous fat grafting can be performed to enhance the final outcome by correcting residual contour deformities. Methods: In this series of five patients, an institutional experience is presented using multi-layered adipo-dermal grafts harvested from the supra-pubic area for the restoration of volume and contour in post-surgical temporal hollowing. During the last follow-up, patients were asked to express their satisfaction, which was assessed by a survey. Results: this approach demonstrates a marked improvement in temporal hollowing associated with a low complication rate and good patient satisfaction. Conclusions: the aim of this consecutive case series is to emphasize the effectiveness of this surgical technique as one of the options to address temporal hollowing. [ABSTRACT FROM AUTHOR]

We report a bronchoscopic image of a 36-year-old with significant airway obstruction from obstructive tracheobronchitis secondary to invasive pulmonary aspergillosis. It is rare to see such a severe form of obstructive tracheobronchitis, likely caused by the patient'sp immunocompromised status and rapid progression nature of influenza-associated pulmonary aspergillosis.

Civil infrastructures are constantly exposed to environmental effects that can contribute to deterioration. Early detection of damage is crucial to prevent catastrophic failures. Structural Health Monitoring (SHM) systems are essential for ensuring the safety and reliability of structures by continuously monitoring and recording data to identify damage-induced changes. In this context, self-sensing composites, formed by incorporating conductive nanomaterials into a matrix, offer intrinsic sensing capabilities through piezoresistivity and various conduction mechanisms. The paper reviews how SHM with self-sensing materials can be applied to civil infrastructure while also highlighting important research articles in this field. The result demonstrates increased dissemination of self-sensing materials for civil engineering worldwide. Their use in core infrastructure components enhances functionality, safety, and transportation efficiency. Among nanomaterials used as additions to produce self-sensing materials in small portions, carbon nanotubes have the most citations and, consequently, the most studies, followed by carbon fiber and steel fiber. This highlight identifies knowledge gaps, benchmark technologies, and outlines self-sensing materials for future research. [ABSTRACT FROM AUTHOR]

Background and Objectives: Postoperative monitoring, following free flap surgery, plays a crucial role in ensuring the survival of the flap. However, in microsurgery, not only the immediate postoperative monitoring period but also the choice of the right time for secondary surgeries is crucial for the free flap survival. There is no clear consensus concerning the right choice of timing for secondary surgery. Our aim was to evaluate transepidermal water loss (TEWL), with the objective evaluation tool Tewameter® in free flap surgery to monitor flap autonomization. Materials and Methods: Transepidermal water loss was assessed in 20 patients with microsurgically transplanted free anterior lateral thigh (ALTP) flaps. The transplantation of the ALTP-flap and the postoperative care were administered in accordance with the standard of care of the department. Measures were taken on the free flap and normal skin at follow-ups of 1, 3, and 6 months after initial free flap transplantation. Results: Transepidermal water loss gradually increased to the values found in normal skin, after 6 months. The differences between the two areas demonstrated the smallest variance after 6 months, specifically in the ALTP-flap region. The largest disparities were observed between month 1 and month 6, followed by month 3 and month 6, and month 1 and month 3. Conclusions: Free flap autonomization and physiology are complex processes. TEWL might be a valuable parameter to monitor flap autonomization. Our results indicate that TEWL in the free flap is nearly "normal" after six months. For a clear consensus of when to perform individual secondary surgery, further studies are needed.

Objective: Primary tracheal tumors are very rare and their management is not definitely established. Due to its rarity, providing patient care in terms of optimal management poses a considerable challenge. The purpose of this study was to investigate treatment outcomes in patients with these rare tumors. Methods: We carried out a retrospective analysis of 89 patients with primary tracheal tumors treated at the Maria Sklodowska-Curie National Research Institute of Oncology in Warsaw, Poland, over sixteen years. The study assessed patient demographics, tumor characteristics and treatment. Different treatment options were compared in terms of overall survival, disease-free survival, and progression-free survival. Results: A total of 89 patients were included in the study. In the group presented, 45 patients underwent primary radical treatment and 44 were qualified for palliative treatment. Surgical resection was performed in 13 patients out of radically treated patients. The 5 year OS rates in the group of patients who underwent radical treatment and in the group of patients who underwent palliative treatment were 45.9% and 2.3%, respectively. In the group of patients who underwent radical surgical treatment, the 5 year OS was 76.9% compared to 35.8% in the group of patients who underwent nonsurgical treatment. Conclusion: A multidisciplinary team should decide treatment options, including in-depth consideration of surgical treatment options. [ABSTRACT FROM AUTHOR]

Introduction: The primary aim of meningioma surgery should be total excision. However, subtotal excision is considered first if the main vascular structures and the cranial nerves are at risk. The ‘primum non nocere’ principle should always be considered. A clinical study where the emphasis is on en bloc resection without debulking in suitable cases, in contrast to the classic approaches, could therefore prove useful. Method: The meningioma cases operated at the İzmir Bakırçay University Çiğli Training and Research Hospital’s Neurosurgery Clinic between 2021 and 2023 were retrospectively evaluated. There were no exclusion criteria. The demographic features of the patients who had undergone debulking or en bloc resection and the anatomical, pathological, surgical and clinical features of the meningiomas were evaluated and the results were presented as percentages. Results: A total of 21 patients, consisting of 5 males (23.8%) and 16 females (76.2%), were included in the study. The mean age was 58.8 (28-90) years. En bloc resection was performed in 18 (85.7%) and debulking in 3 (14.3%) of the 21 cases. The other results are presented within the article. Conclusion: En bloc resection could be an important surgical strategy to decrease the surgical duration and bleeding amount in appropriate cases. [ABSTRACT FROM AUTHOR]
