Early Intervention in Septic Arthritis of the Hand, Optimizing Patient Outcomes in Hand Infections-A Five-Year Retrospective Study.

Background and Objectives: Hand septic arthritis is a potentially debilitating condition that can significantly affect patient functionality and quality of life. Understanding the demographic, clinical, and microbiological characteristics of this condition is crucial for its effective treatment and management. This study aimed to analyze the demographic and clinical profiles of patients with hand septic arthritis, to identify common microbial pathogens, and to evaluate the impact of various factors on clinical course and treatment outcomes. Material and Methods: This cross-sectional retrospective study examined patients diagnosed with septic arthritis of the hand, focusing on their demographic data, clinical presentation, causative organisms, treatment methods, and outcomes. Data on age, sex, cause of infection, affected sites, surgical interventions, microbiological findings, and patient outcomes were also collected. Results: This study found a higher prevalence of septic arthritis in males and identified bite as the predominant cause. Staphylococcus aureus is the most common pathogen. A large number of patients did not exhibit bacterial growth, and bacterial resistance did not significantly affect the outcome. Outcomes were statistically influenced by the timing of medical presentation and the presence of comorbidities. Conclusions: Early diagnosis and intervention are critical for effective management of hand septic arthritis. This study underscores the need for a comprehensive approach that considers patient demographic and clinical characteristics to optimize treatment outcomes. Awareness and preventive measures are essential to reduce the incidence and severity of this condition.

Exploring Costimulatory Blockade-Based Immunologic Strategies in Transplantation: Are They a Promising Immunomodulatory Approach for Organ and Vascularized Composite Allotransplantation?

The field of transplantation, including the specialized area of vascularized composite allotransplantation (VCA), has been transformed since the first hand transplant in 1998. The major challenge in VCA comes from the need for life-long immunosuppressive therapy due to its non-vital nature and a high rate of systemic complications. Ongoing research is focused on immunosuppressive therapeutic strategies to avoid toxicity and promote donor-specific tolerance. This includes studying the balance between tolerance and effector mechanisms in immune modulation, particularly the role of costimulatory signals in T lymphocyte activation. Costimulatory signals during T cell activation can have either stimulatory or inhibitory effects. Interfering with T cell activation through costimulation blockade strategies shows potential in avoiding rejection and prolonging the survival of transplanted organs. This review paper aims to summarize current data on the immunologic role of costimulatory blockade in the field of transplantation. It focuses on strategies that can be applied in vascularized composite allotransplantation, offering insights into novel methods for enhancing the success and safety of these procedures.

Reconstructive Paradigms: A Problem-Solving Approach in Complex Tissue Defects.

The field of plastic surgery is continuously evolving, with faster-emerging technologies and therapeutic approaches, leading to the necessity of establishing novel protocols and solving models. Surgical decision-making in reconstructive surgery is significantly impacted by various factors, including the etiopathology of the defect, the need to restore form and function, the patient's characteristics, compliance and expectations, and the surgeon's expertise. A broad surgical armamentarium is currently available, comprising well-established surgical procedures, as well as emerging techniques and technologies. Reconstructive surgery paradigms guide therapeutic strategies in order to reduce morbidity, mortality and risks while maximizing safety, patient satisfaction and properly restoring form and function. The paradigms provide researchers with formulation and solving models for each unique problem, assembling complex entities composed of theoretical, practical, methodological and instrumental elements.

Occurrence of Chlamydia spp. in Conjunctival Samples of Stray Cats in Timișoara Municipality, Western Romania.

Despite the widespread public health concern about stray cats serving as reservoirs for zoonotic agents, little is known about the effect of urban and peri-urban landscapes on exposure risk. We conducted this study to monitor the presence of Chlamydia spp. in stray cats, with or without conjunctivitis, living in Timișoara Municipality, Western Romania, using staining and PCR methods. A total of 95 cats were enrolled, and conjunctival samples were harvested from 68 clinically healthy cats and another 27 cats presenting with clinical signs of conjunctivitis. Overall, we found that 65.3% (62/95) of the cats tested positive for Chlamydia spp. by PCR. Chlamydia spp. were detected in 45/95 conjunctival samples using a standard Giemsa stain, compared with 62/95 using PCR (Cohen's kappa index = 0.308; p = 0.0640). Of the cats that tested positive by PCR, 72.6% (45/62) were asymptomatic, and another 27.4% (17/62) expressed clinical signs of conjunctivitis. We found no significant difference between (p > 0.05) the distribution of infection and the recorded epidemiological data (sex, breed, age, territorial distribution, or sampling season). However, the Chlamydia spp. detection frequency was significantly higher in asymptomatic than in symptomatic cats (p = 0.0383). The obtained results increase the level of concern and awareness about the possible zoonotic potential of this pathogen and highlight that urban stray cats can be essential sources of feline chlamydiosis.

Benign cartilaginous tumors of the hand, a five-year retrospective study.

Benign and malignant cartilaginous bone tumors of the hand are rare findings, however representing a particular pathology due to the capacity to induce significant functional impairment. Even though a large proportion of tumors of the hand and wrist are benign, these may present destructive characteristics, deforming adjacent structures until compromising function. The most appropriate surgical approach for most benign tumors is intralesional lesion resection. Malignant tumors often require wide excision, up to segment amputation to obtain tumor control. A five-year retrospective study was performed on patients admitted in our Clinic with benign cartilaginous tumors of the hand, in which 15 patients were admitted within this period, 10 presenting with enchondroma, four presenting with osteochondroma, and lastly one with chondromatosis. After clinical and imaging evaluation, all the aforementioned tumors were surgically removed. Definitive diagnosis for all bone tumors, either benign or malignant, was established by tissue biopsy and histopathological examination, dictating therapeutic strategy.

Clinical and pathological features of upper limb nerve tumors - four years retrospective study.

Benign peripheral nerve tumors and malignant peripheral nerve tumors are rarely found in patients with upper limb tumors. A four-year retrospective study was conducted on patients with tumors in the upper limb area admitted to the Emergency Clinical Hospital, Bucharest, Romania. Seventeen patients were admitted within this time range, 15 of which were benign and two malignant. All patients required surgical intervention after thorough clinical and imaging evaluation. Benign masses were removed, follow-up examination revealing no local recurrent, as well as good function recovery. On the other hand, malignant tumors due to their highly aggressive features, both determined local recurrence, one requiring upper limb amputation, the other presenting metastases.
