Isolated volar distal radioulnar joint (DRUJ) dislocation is a rare condition with only a few cases reported in the literature. Its diagnosis is often overlooked in the acute phase, and there is no consensus in its management. We present the case of a 20-year-old male patient with an isolated volar radioulnar dislocation, together with a review of the literature. The aim is to present and summarize the acute management of this condition and propose a therapeutic algorithm.

Triceps tendon ruptures are rare but significant injuries that impair upper extremity function. Despite their infrequency, recognizing this condition is crucial due to its severe impact on arm movement and strength. Patients typically present with posterior elbow pain, swelling, and bruising.This report details a complete triceps tendon rupture in a 34-year-old male following trauma. The patient exhibited classic symptoms: posterior elbow pain, significant swelling, and visible bruising, initially suggesting a severe soft tissue injury. Clinical examination and imaging confirmed a complete triceps tendon rupture. This case highlights the importance of considering triceps tendon rupture in patients with similar symptoms, particularly after trauma. Early recognition and accurate diagnosis are essential for timely surgical intervention, significantly improving functional recovery. Delayed diagnosis and treatment can lead to prolonged disability and poor outcomes, emphasizing the need for heightened awareness among healthcare providers regarding this rare but serious injury.

Isolated spontaneous superior mesenteric artery (SMA) dissection is relatively rare. Often found incidentally on cross-sectional imaging, often managed non-operatively. We present a patient who presented with chest pain and was found to have a SMA dissection.

This study prospectively evaluated the effects of digitally enabled peer support on mental health outcomes and estimated medical cost reductions among vulnerable adults with symptomatic depression, anxiety, and significant loneliness to address the mental health crisis in the United States.

BACKGROUND: Malignant melanoma is a highly invasive tumor with very poor prognosis. Common metastases of MM are noted in lungs, Central nervous system, liver, lymph nodes and isolated spinal metastases are extremely rare. To our knowledge only one case of isolated lumbar spinal metastases of MM was reported.
METHODS: An 80-year-old female presented with pain at upper thoracic spine and progressive weakness of bilateral lower limbs. She gives history of recurrent MM of nose, for which she underwent excision of tumor twice. On examination she had spastic gait with exaggerated lower limb reflexes and lower limb motor grade of 3/5. The MRI scan of thoracic spine revealed lobulated enhancing mass involving the right half of the T3 vertebral body and corresponding posterior elements. The patient underwent palliative spinal decompression and excision of tumor. Histopathology confirmed MM. The PET scan done post operatively ruled out any other sites of metastases.
CONCLUSIONS: Though the incidence of isolated manifestation of spinal metastases of MM is extremely rare, clinical suspicion and advanced imaging can help to diagnose early. The treatment strategy should be guided by current neurological status, nature of the tumor, presence of mechanical instability and patient\'s fitness to undergo surgical intervention.
CONCLUSIONS: Patient diagnosed with MM should be closely followed up even in absence of any recurrence at the primary site. Surgical decompression can improve neurological symptoms and decrease pain to improve quality of life even at advanced stage of the disease.

Diabetic wound infections including diabetic foot ulcers (DFUs) are a major global health concern and a leading cause of non-traumatic amputations. Numerous bacterial species establish infection in DFUs, and treatment with antibiotics often fails due to widespread antibiotic resistance and biofilm formation. Determination of bacterial species that reside in DFU and their virulence potential is critical to inform treatment options. Here, we isolate bacteria from debridement tissues from patients with diabetes at the University of Colorado Anschutz Medical Center. The most frequent species were Gram-positive including Enterococcus faecalis, Staphylococcus aureus, and Streptococcus agalactiae, also known as Group B Streptococcus (GBS). Most tissues had more than one species isolated with E. faecalis and GBS frequently occurring in polymicrobial infection with S. aureus. S. aureus was the best biofilm producing species with E. faecalis and GBS isolates exhibiting little to no biofilm formation. Antibiotic susceptibility varied amongst strains with high levels of penicillin resistance amongst S. aureus, clindamycin resistance amongst GBS and intermediate vancomycin resistance amongst E. faecalis. Finally, we utilized a murine model of diabetic wound infection and found that the presence of S. aureus led to significantly higher recovery of GBS and E. faecalis compared to mice challenged in mono-infection.

Sarcoidosis is a multi-organ inflammatory disease that can have hepatic involvement in up to 80% of cases. Rarely, sarcoidosis can manifest with only confined disease to the liver. While most patients with hepatic sarcoidosis are clinically silent, certain cases can have insidious onset leading to cirrhosis and secondary complications. Here, we describe three cases of isolated hepatic sarcoidosis to illustrate the range of presentations that may be associated with this condition. Clinicians should be vigilant in consideration of hepatic sarcoidosis as a culprit when investigating patients with undifferentiated liver disease.

UNASSIGNED: Tibiocalcaneal arthrodesis (TCA) can be achieved by internal fixation (intramedullary nail or plate), external fixation, or a combination. Evidence for the optimal approach is limited. This systematic review examines the outcomes of these different approaches to guide surgical management.
UNASSIGNED: A MEDLINE and Oxford SOLO search was performed using \"tibiocalcaneal,\" \"ankle,\" \"fusion OR arthrodesis.\" The primary outcome was union. Secondary outcomes included rates of postoperative complications, weightbearing status, rates of revision surgery, and PROMs. We included any studies with follow-up greater than 6 months that contained our primary outcome and at least 1 secondary outcome.
UNASSIGNED: The initial search yielded 164 articles, of which 9 studies totaling 53 cases met the criteria. The majority of articles were excluded because they were nonsurgical studies, or were not about isolated TCA but were for tibiotalocalcaneal arthrodesis, more complex reconstructions (eg, Charcot), case reports, and/or did not include the predetermined outcome measures.TCA union rate was 86.2% following external fixation, 82.4% for intramedullary nail fixation, and 83.3% for plate fixation. One patient underwent a hybrid of external and internal fixation, and the outcome was nonunion. The rate of complications following TCA was 69.8%.
UNASSIGNED: There is limited evidence on the best operative approach for isolated tibiocalcaneal arthrodesis. Both external and internal fixation methods had comparable union rates. External fixation had frequent complications and a more challenging postoperative protocol. Novel techniques such as 3D-printed cages and talus replacement may become a promising alternative but require further investigation.

BACKGROUND: Hemodynamic classification of pulmonary hypertension (PH) has important clinical implications. However, only a few echocardiographic variables have been used to hemodynamically classify PH in dogs.
OBJECTIVE: To evaluate the echocardiographic pulmonary to left atrial ratio index (ePLAR) in dogs with PH.
METHODS: Forty-six dogs with intermediate to high probability of PH.
METHODS: Cross-sectional study. Variables were compared between dogs with precapillary PH [PrePH (n = 24)] vs postcapillary PH [PostPH (n = 22)], and with combined PH [CombPH (n = 14)] vs isolated PH [IsoPH (n = 8)] using the t-, Mann-Whitney, Pearson\'s Chi, or Fisher\'s exact test. The receiver operating characteristic curve and Youden index were used to identify the optimal ePLAR cutoff value to differentiate among the groups, intraclass correlation coefficients (ICC) were used to determine the reliability of measurements.
RESULTS: The mean (SD) ePLAR of the PrePH was higher than that of the PostPH group [0.36 (0.13) vs 0.26 (0.09), respectively; P = .005]. The median (interquartile range) ePLAR of the CombPH was higher than that of the IsoPH subgroup [0.29 (0.24-0.38), vs 0.20 (0.16-0.23), respectively; P = .001]. The best cutoff value of ePLAR for identifying IsoPH was <0.245 [AUC at cutoff point = 0.86; sensitivity (95% confidence interval [CI]) = 0.71 (0.47-0.95); specificity (95% CI) = 1 (0.76-1)]. The ICC analysis indicated a high degree of reliability.
CONCLUSIONS: ePLAR can be considered a valid noninvasive variable to hemodynamically classify PH in dogs with an intermediate to high probability of PH. Assessment of ePLAR can be useful in the therapeutic management of PH in dogs.

BACKGROUND: Isolated splenic vein thrombosis (iSVT) is a common complication of pancreatic disease. Whilst patients remain asymptomatic, there is a risk of sinistral portal hypertension and subsequent bleeding from gastric varices if recanalisation does not occur. There is wide variation of iSVT treatment, even within single centres. We report outcomes of iSVT from tertiary referral hepatobiliary and pancreatic (HPB) units including the impact of anticoagulation on recanalisation rates and subsequent variceal bleeding risk.
METHODS: A retrospective cohort study including all patients diagnosed with iSVT on contrast-enhanced CT scan abdomen and pelvis between 2011 and 2019 from two institutions. Patients with both SVT and portal vein thrombosis at diagnosis and isolated splenic vein thrombosis secondary to malignancy were excluded. The outcomes of anticoagulation, recanalisation rates, risk of bleeding and progression to portal vein thrombosis were examined using CT scan abdomen and pelvis with contrast.
RESULTS: Ninety-eight patients with iSVT were included, of which 39 patients received anticoagulation (40%). The most common cause of iSVT was acute pancreatitis n = 88 (90%). The recanalisation rate in the anticoagulation group was 46% vs 15% in patients receiving no anticoagulation (p = 0.0008, OR = 4.7, 95% CI 1.775 to 11.72). Upper abdominal vascular collaterals (demonstrated on CT scan angiography) were significantly less amongst patients who received anticoagulation treatment (p = 0.03, OR = 0.4, 95% CI 0.1736 to 0.9288). The overall rate of upper GI variceal-related bleeding was 3% (n = 3/98) and it was independent of anticoagulation treatment. Two of the patients received therapeutic anticoagulation.
CONCLUSIONS: The current data supports that therapeutic anticoagulation is associated with a statistically significant increase in recanalisation rates of the splenic vein, with a subsequent reduction in radiological left-sided portal hypertension. However, all patients had a very low risk of variceal bleeding regardless of anticoagulation. The findings from this retrospective study should merit further investigation in large-scale randomised clinical trials.
