BACKGROUND: With the rise in the mastectomy rate, the number of patients who choose to undergo postmastectomy reconstruction has been increasing, and implant-based procedures are the most performed methods for postmastectomy breast reconstruction. Among the possible complications, the most feared is the loss of reconstruction. It can be related to several reasons, but one of the most common is infection of the implant, which can lead to prolonged antibiotic treatment, undesired additional surgical procedures, increased incidence of capsular contracture, and unsatisfactory aesthetics results, with a huge psychological impact on patients.
OBJECTIVE: The primary intent of this study is to analyze the status of infection rates at our institution and evaluate the effectiveness of our prevention protocol since its introduction. Secondly, we compared data of the surgical site infections (SSIs) after implant-based breast reconstruction at Trieste Hospital, where the protocol has been employed since 2020, and in another center, where plastic surgeons of our team are involved, with different prevention procedures.
RESULTS: We enrolled 396 female patients, who underwent implant-based breast reconstruction, using definitive mammary implants or breast tissue expanders, with or without ADM (acellular dermal matrix), both for breast cancer and risk-reducing surgery in BRCA1/2 patients. Patients treated at the Hospital of Trieste, with the use of the prevention protocol, were considered the experimental group (group 1), while patients treated in Gorizia by the same breast team with standardized best-practice rules, but without the use of the prevention protocol, were considered the control group (group 2). Infected patients were 5 in the first group (1.7%) and 8 in the second one (7.9%), with a global infection rate of 3.2%.
CONCLUSIONS: After the introduction of our prevention protocol, we faced a lower incidence of infection after breast surgery with implants or tissue expanders.

Background Fingertip injuries with volar pulp tissue defects present a significant challenge in management. This study aimed to evaluate the efficacy of a conservative treatment protocol using artificial dermis and semi-occlusive dressings for these injuries. Methods A single-center, prospective study was conducted on 31 patients with fingertip injuries involving volar pulp defects. The treatment protocol included wound debridement, application of artificial dermis (Pelnac®), and a semi-occlusive dressing (IV3000®). The outcomes were assessed using subjective questionnaires and objective measures, including fingerprint regeneration, sensory function, pain, and cosmetic appearance. Results The mean treatment duration was 45.29 days (SD = 17.53). Complications were minimal, with only one case (3.22%) directly attributable to the treatment. Fingerprint regeneration was considerable (mean score = 2.58, SD = 0.67). The sensory disturbances were minimal, with no significant differences across injury types. Post-treatment pain was low (mean = 0.45, SD = 0.67), and cosmetic satisfaction was high (mean = 4.09, SD = 0.94). The overall patient satisfaction was high (mean = 4.41, SD = 0.67), regardless of injury severity. Conclusions The conservative treatment protocol using artificial dermis and semi-occlusive dressings is a promising strategy for managing fingertip injuries with volar pulp defects. This approach minimizes surgical morbidity and achieves excellent functional and aesthetic outcomes.

BACKGROUND: Short harvested right renal veins (RV) are quite common in living donor kidney transplantation (KT). This technical difficulty might interfere implanting and increase warm ischemic time. Several techniques to overcome this problem have been applied, including iliac vein transposition, inverted transplant, synthetic graft, saphenous vein… Application of accompanying gonadal vein (GV), which is easily approachable and less time-consuming, has been recently published. This study aims to evaluate its effectiveness and safety.
METHODS: Retrospective study on KT using the gonadal vein to lengthen the short right renal vein at Viet Duc University Hospital from April 2019 to April 2022. The following data were gathered: baseline characteristics, vascular imaging in CT scan/after nephrectomy and after reconstruction (mm), reconstruction and surgical time, hospitalization days. The outcomes were determined by kidney function after transplantation (plasma creatinine, creatinine clearance) and related complications.
RESULTS: Twenty-five cases with procured right kidney with short RV from the living donor which were reconstructed and lengthened by the accompanying GV were collected. The additional length of RV was 15.9 ± 2.4 mm. Average cold ischemic time, venoplasty time, warm ischemic time were 60.4 ± 8.2, 21.2 ± 5.3, and 38.1 ± 5.6 min, respectively. The average hospital stay was 15.3 ± 3.2 days. Average follow-up time was 31 ± 5.2 months, creatinine clearance was around 60 ml/min after 1 year, no vascular or urologic complications was observed.
CONCLUSIONS: Accompanying GV from a living donor to lengthen short right RV in KT is a feasible, safe, and effective technique.

We report a case of a 54-year-old female who presents with a gradually expanding mass at the right lateral malleolus. The diagnosis of undifferentiated pleomorphic sarcoma was made after a histopathological examination of the mass following a wide tumor excision. The defected soft tissue area was reconstructed using a local flap, reverse sural artery flap. Following the surgical management, multiple radiotherapy sessions were completed. The patient\'s follow-up result showed no signs of local recurrence or metastasis, and the wound was well-healed with no complications other than paresthesia in a small area at the posterolateral aspect of the ankle under the lateral malleolus. This case represents a rare form of malignant neoplasm and emphasizes the effectiveness and safety of the reverse sural artery flap reconstruction technique, especially in places where microsurgery is unavailable or when the patient\'s status does not allow for prolonged anesthesia.

UNASSIGNED: To study a surgical approach to venous vascular thrombosis after uterus transplantation (UTx). Uterus transplantation is the only treatment for uterine factor infertility when conventional therapies are not possible. One of the major limitations of UTx is the high incidence of vascular thrombosis, which in most series reaches approximately 20%.
UNASSIGNED: A case report.
UNASSIGNED: Hospital.
UNASSIGNED: We report here a technique used in a 30-year-old woman with congenital absence of the uterus who developed intraoperative thrombosis after a UTx from a brain-dead donor.
UNASSIGNED: The UTx was performed by revascularizing the graft through bilateral donor internal iliac vessels (artery and vein) anastomosed end-to-side to the external iliac vessels of the recipient. The superior uterine veins were not anastomosed and were left unreconstructed. An end-to-end graft to the recipient\'s vaginal anastomosis was performed. After uterus reperfusion, congestion of the organ was noted, and bilateral venous thrombosis of the internal iliac veins of the graft was found. A \"Y-shaped\" venous jump graft was used to restore venous outflow of the left superior uterine vein and the internal iliac vein of the graft after thrombectomy.
UNASSIGNED: Viability and functionality of the uterus graft after intraoperative bilateral venous thrombosis.
UNASSIGNED: The postoperative course was uneventful, and this UTx resulted in the delivery of a healthy infant.
UNASSIGNED: To our knowledge, this is the first successful rescue technique used to restore venous outflow and save the viability and functionality of a transplanted uterus. We demonstrated that a transplanted uterus from a deceased donor with a monolateral outflow could succeed in pregnancy and the delivery of a healthy infant.

BACKGROUND: Total patellectomy is currently reserved for exceptional cases, such as recalcitrant patellofemoral instability and comminuted fractures, due to its demonstrated negative impact on knee biomechanics. Therefore, managing patellectomy is crucial to mitigate its inherent deleterious effects. Various techniques have been described, including autologous or allogeneic bone grafts for reconstruction and soft tissue realignment to enhance the extensor mechanism.
METHODS: A 73-year-old male underwent a patellectomy due to a comminuted fracture, subsequently developing osteoarthritis and experiencing a decline in functional status. Concurrent with total knee replacement, we conducted a patellar reconstruction, incorporating routine bone cuts and utilizing bone chips to fashion a new patella. This intervention resulted in the restoration of full extension and improvement of knee function.
CONCLUSIONS: Patellar reconstruction demonstrates benefits on knee mechanics and stabilization, contributing to enhanced outcomes and satisfaction following knee replacement. We present an affordable technique for managing patellectomized patients undergoing total knee replacement.

UNASSIGNED: Surgical reconstruction is often necessary for severe tracheobronchial stenosis resulting from tuberculosis (TB). However, the long-term efficacy of this approach remains unclear. This study investigated the safety and long-term outcomes of surgery for severe post-TB tracheobronchial stenosis.
UNASSIGNED: We conducted a retrospective study of 48 patients with severe post-TB tracheobronchial stenosis who underwent surgical reconstruction between 2015 and 2018 in a TB-endemic region. Pre- and postoperative evaluations included Karnofsky performance status, modified Medical Research Council (mMRC) dyspnea scale, spirometry, chest computed tomography (CT) scan, and bronchoscopy. The primary outcome was intervention-requiring restenosis over the long term.
UNASSIGNED: The mean patient age was 30.6±9.9 years, with 91.7% females. Airway fibrosis was the predominant lesion (93.8%), affecting the bronchi (93.8%) and trachea (6.2%). All the patients underwent resection and anastomosis, and 56.2% required lobectomy. Postoperative complications occurred in 13 patients (27.1%), with prolonged air leaks being the most prevalent (12.5%). All complications resolved with conservative management. Significant improvements in performance status, dyspnea, and lung function were observed postoperatively and sustained for over 5 years. Within a median follow-up of 69 months, five cases of intervention-requiring restenosis occurred within the first year. The freedom from restenosis rate was 90% from 1 year onwards.
UNASSIGNED: Surgical reconstruction is safe and effective in treating severe post-TB tracheobronchial stenosis. Larger studies are required to validate these findings.

The retinal neural circuit is intricately wired for efficient processing of visual signals. This is well-supported by the specialized connections between retinal neurons at both the functional and ultrastructural levels. Through 3D electron microscopic (EM) reconstructions of retinal neurons and circuits we have learnt much about the specificities of connections within the retinal layers including new insights into how retinal neurons establish connections and perform sophisticated visual computations. This mini-review will summarize the retinal circuitry and provide details about the novel insights EM connectomics has brought into our understanding of the retinal circuitry. We will also discuss unresolved questions about the retinal circuitry that can be addressed by EM connectomics in the future.

BACKGROUND: The ideal approach for treating anterior cruciate ligament (ACL) injury is still disputed. This study aimed to determine the more cost-effective strategy by comparing early ACL reconstruction (ACLR) surgery to conservative treatment (rehabilitation with optional delayed reconstruction) for ACL injury in a lower/middle-income country (LMIC), Indonesia.
METHODS: A decision tree model was constructed for cost-utility analysis of early ACLR versus conservative treatment. The transition probabilities between states were obtained from the literature review. Utilities were measured by the EQ-5D-3 L from a prospective cohort study in a local hospital. The costs were obtained from a previous study that elaborated on the burden and cost of ACLR in Indonesia. Effectiveness was expressed in quality-adjusted life years gained (QALYs). Principal outcome measure was the incremental cost-effectiveness ratios (ICER). Willingness-to-pay was set at US$12,876 - three times the Indonesian GDP per capita in 2021 - the currently accepted standard in Indonesia as suggested by the World Health Organization Choosing Interventions that are Cost-Effective criterion (WHO-CHOICE).
RESULTS: The early ACLR group showed an incremental gain of 0.05 QALYs over the conservative treatment group, with a higher overall cost to society of US$976. The ICER of ACLR surgery was US$19,524 per QALY, above the WTP threshold of US$12,876. The ICER was sensitive to cost of conservative treatment, cost of ACLR, and rate of cross-over to delayed ACLR numbers in the conservative treatment group. Using the WTP threshold of US$12,876, the probability of conservative treatment being preferred over early ACLR was 64%.
CONCLUSIONS: Based on the current model, early ACLR surgery does not seem more cost-effective compared to conservative treatment for ACL injury patients in Indonesia. Because the result was sensitive to the rate of cross-over probabilities from the conservative treatment alone to delayed ACLR, a future study with a long-term perspective is needed to further elucidate its impact.

The pectoralis major myocutaneous flap (PMMF) was described by Ariyan in 1979 for head and neck reconstructions. It is a safe flap, currently supplanted by free flaps in developed countries, but which remains very useful in developing countries. We report a series of 25 cases of PMMF reconstruction. All patients were treated for advanced stages of oral cavity cancer, where tumor excision left significant tissue loss. The reconstruction used PMMF, taken using the same technique. Supplanted by free flaps in developed countries, PMMF remains useful in developing countries. It is a flap that has numerous advantages (ease of collection, viability, low requirements in terms of instrumentation, etc.). Many variations have been described over the years.
