The time cut-off for primary closure of acute wounds is not clearly defined in the literature or in the surgical textbooks. It is even unclear whether the wound age increases wound infection rate. The scarcity of scientific evidence may explain the diverse ...
Breast cancers (BC) are usually classified into four molecular subtypes according to the expression of estrogen (ER), progesterone (PR), and human epidermal growth factor 2 (HER2) receptors and proliferation marker Ki-67. Despite available anti-hormonal therapies and due to the inherent propensity of some subtypes to develop metastasis, there is a permanent need to discover new prognostic and predictive biomarkers, as well as therapeutic targets for BC. In this study, we used immunohistochemical staining to determine the expression of androgen receptor (AR) and sonic hedgehog protein (SHH), the main ligand of the Hedgehog-GLI (HH-GLI) signaling pathway, in 185 archival primary BC tissue samples and correlated it with clinicopathological characteristics, molecular subtypes, receptors statuses, and survival in a cohort of Croatian BC patients. Results showed that higher SHH and AR expressions were associated with positive receptor status, but increased SHH expression had a negative impact on survival in receptor-negative BCs. On the contrary, higher AR expression was mostly protective. However, multivariate analysis showed that only higher AR expression could be considered as an independent prognostic biomarker for poorer overall survival in triple-negative breast cancer patients (TNBC) (HR 10.9, 95% CI 1.43–83.67; p = 0.021), what could be Croatian population-related. SHH could be a potential target for treating TNBCs and HER2-enriched BCs, in cases where HH-GLI signaling is canonical (SHH-dependent).
Background: Frostbite is a severe injury characterized by tissue damage due to exposure to freezing temperatures. It often necessitates prompt medical intervention to prevent further complications such as necrosis and amputation. This case report explores the successful use of bilateral anterolateral thigh (ALT) free flaps for feet salvage in a 19-year-old male refugee from Gambia who suffered severe frostbite injuries. Case Report: The patient, found after six days in freezing conditions, exhibited necrosis on multiple toes. Initial management included stabilization, intravenous fluids, and rewarming. Subsequent necrectomy and amputation revealed exposed metatarsal bones, necessitating a meticulous reconstructive strategy. Bilateral ALT flaps were chosen to preserve walking function, with a staged reconstruction involving multiple operations. The patient’s progress, from inpatient care to outpatient follow-ups, is detailed, emphasizing the challenges and decisions in managing severe frostbite injuries. Results: The surgical intervention utilizing bilateral ALT flaps successfully salvaged the patient’s feet. Throughout the postoperative period, wound care, rehabilitation, and outpatient monitoring contributed to positive outcomes. Despite challenges associated with the patient’s ethnic background and nutritional status, the staged reconstruction facilitated effective healing and functional recovery. The use of ALT flaps provided a reliable solution with minimal donor site morbidity. Conclusion: This case highlights the efficacy of bilateral ALT flap reconstruction in salvaging feet following severe frostbite injury. The successful restoration of foot function underscores the importance of early intervention and tailored reconstructive approaches in frostbite management. Despite patient-specific challenges, including nutritional status and limited healthcare resources, the use of ALT flaps facilitated optimal recovery and functional outcomes. Importantly, this report is unique as it describes a novel case of feet salvage using bilateral ALT flaps in severe frostbite injury, with only one similar case previously reported in the literature. This emphasizes the rarity and significance of this specific surgical approach in frostbite management.

Herein we report a case of a male patient who was burned with hot oil and as a consequence developed a severe axillary contracture with limited abduction and elevation of his left arm. Due to the restriction in the range of movements, our patient reported limitations in everyday activities with decreased quality of life. For this patient we proposed a reconstructive plan that required a combination of multiple techniques of scar release and reconstruction of the defect with thoracodorsal artery perforator (TDAP)-based flap. One year postoperatively, we achieved a significant improvement in range of motion. We showed that TDAP flap provides a thin and pliable tissue coverage with a safe vascular supply. Furthermore, we eliminated the need for prolonged splinting which enabled early postoperative rehabilitation. To conclude, TDAP flap proved to be an ideal flap for this scenario and when used in combination with other techniques, optimal end result can be achieved.
Background: The latissimus dorsi free flap is a workhorse for extensive lower-extremity soft tissue defects. Conventionally, the skin paddle is designed according to the anticipated defect and left in place on the muscle as a single composite unit. This report describes an alternative approach in which the skin paddle is secondarily mobilized through subcutaneous undermining and rotated as a separate propeller-type local extension flap on random-pattern vascularization, without a specifically identified perforator—a technique that has not been previously reported. Case Presentation: A 38-year-old male with a high-energy distal lower-extremity defect exposing bone, Achilles tendon, and hardware underwent free latissimus dorsi reconstruction with an empirically designed skin paddle over the constant perforator zone. The skin paddle was subsequently mobilized and rotated as a separate propeller-type extension flap to cover the Achilles region, with additional areas managed using split-thickness skin graft and a reverse soleus flap. Results: The latissimus dorsi flap and skin paddle remained viable, providing stable coverage of the defect. The additional reverse soleus flap achieved durable medial coverage, and the limb was ultimately preserved with satisfactory soft-tissue stability. Conclusion: A random-pattern latissimus dorsi skin paddle designed within the anatomically constant perforator zone can provide a feasible new option offering intraoperative flexibility in complex lower-extremity trauma when perforator mapping is impractical.
