Liposarcomas of the spermatic cord are rare and often clinically and histologically misdiagnosed, leading to ineffective management and poor outcomes. We present a case of metastatic dedifferentiated liposarcoma of the spermatic cord, which recurred after excision of a misdiagnosed well-differentiated liposarcoma 3 years prior. Due to its size and high-grade metastasis, the tumor was unresectable, leading to treatment with systemic chemotherapy. Complications arose including partial compression of the testicular artery and urethral obstruction secondary to local mass effect. Tumor biopsy was characterized by a unique immunohistochemical profile which helped to explain the unique processes leading to mass effect, vascular and urethral compression, and bilateral scrotal swelling. The patient’s family history of malignancy and 22/22q trisomy identified in the tumor biopsy were also interesting contributors. In conclusion, accurate diagnosis of spermatic cord tumors is essential for effective treatment, and further data collection is required to improve management of advanced metastatic disease.

Purpose: Preoperative identification of the intraosseous posterior superior alveolar artery (PSAA) is critical when planning sinus surgery. This study was conducted to determine the distance between the cementoenamel junction and the PSAA, as well as to identify factors influencing the detection of the PSAA on cone-beam computed tomography (CBCT). Materials and Methods: In total, 254 CBCT scans of maxillary sinuses, acquired with 2 different scanners, were examined to identify the PSAA. The distance from the cementoenamel junction (CEJ) to the PSAA was recorded at each maxillary posterior tooth position. Binomial logistic regression and multiple linear regression were employed to evaluate the effects of scanner type, CBCT parameters, sex, and age on PSAA detection and CEJ-PSAA distance, respectively. P-values less than 0.05 were considered to indicate statistical significance. Results: The mean CEJ-PSAA distances at the second molar, first molar, second premolar, and first premolar positions were 17.0±4.0 mm, 21.8±4.1 mm, 19.5±4.7 mm, and 19.9±4.9 mm for scanner 1, respectively, and 17.3±3.5 mm, 16.9±4.3 mm, 18.5±4.1 mm, and 18.4±4.3 mm for scanner 2. No independent variable significantly influenced PSAA detection. However, tooth position (b = - 0.67, P<0.05) and scanner type (b = - 1.3, P<0.05) were significant predictors of CEJ-PSAA distance. Conclusion CBCT-based estimates of CEJ-PSAA distance were comparable to those obtained in previous studies involving cadavers, CT, and CBCT. The type of CBCT scanner may slightly influence this measurement. No independent variable significantly impacted PSAA detection.

BACKGROUND AND OBJECTIVES: Right ventricular longitudinal strain (RVLS) is a new parameter of RV function. We evaluated the relationship of RVLS by speckle-tracking echocardiography with functional and invasive parameters in pulmonary arterial hypertension (PAH) patients. SUBJECTS AND METHODS: Thirty four patients with World Health Organization group 1 PAH (29 females, mean age 45+/-13 years old). RVLS were analyzed with velocity vector imaging. RESULTS: Patients with advanced symptoms {New York Heart Association (NYHA) functional class III/IV} had impaired RVLS in global RV (RVLS(global), -17+/-5 vs. -12+/-3%, p<0.01) and RV free wall (RVLS(FW), -19+/-5 vs. -14+/-4%, p<0.01 to NYHA class I/II). Baseline RVLS(global) and RVLS(FW) showed significant correlation with 6-minute walking distance (r=-0.54 and r=-0.57, p<0.01 respectively) and logarithmic transformation of brain natriuretic peptide concentration (r=0.65 and r=0.65, p<0.01, respectively). These revealed significant correlations with cardiac index (r=-0.50 and r=-0.47, p<0.01, respectively) and pulmonary vascular resistance (PVR, r=0.45 and r=0.45, p=0.01, respectively). During a median follow-up of 33 months, 25 patients (74%) had follow-up examinations. Mean pulmonary arterial pressure (mPAP, 54+/-13 to 46+/-16 mmHg, p=0.03) and PVR (11+/-5 to 6+/-2 wood units, p<0.01) were significantly decreased with pulmonary vasodilator treatment. RVLS(global) (-12+/-5 to -16+/-5%, p<0.01) and RVLS(FW) (-14+/-5 to -18+/-5%, p<0.01) were significantly improved. The decrease of mPAP was significantly correlated with improvement of RVLS(global) (r=0.45, p<0.01) and RVLS(FW) (r=0.43, p<0.01). The PVR change demonstrated significant correlation with improvement of RVLS(global) (r=0.40, p<0.01). CONCLUSION: RVLS correlates with functional and invasive hemodynamic parameters in PAH patients. Decrease of mPAP and PVR as a result of treatment was associated with improvement of RVLS.

Background: s/Aims: After pancreatoduodenectomy (PD), an early oral diet is recommended; however, the postoperative nutritional management of PD patients is known to be highly variable, with some centers still routinely providing parenteral nutrition (PN). Some patients who receive PN experience clinically significant complications, underscoring its judicious use. Using a large cohort, this study aimed to determine the proportion of PD patients who received postoperative nutritional support (NS), describe the nature of this support, and investigate whether receiving PN correlated with adverse perioperative outcomes. Methods: Data were extracted from the Recurrence After Whipple’s study, a retrospective multicenter study of PD outcomes. Results: In total, 1,323 patients (89%) had data on their postoperative NS status available. Of these, 45% received postoperative NS, which was “enteral only,” “parenteral only,” and “enteral and parenteral” in 44%, 35%, and 21% of cases, respectively. Body mass index < 18.5 kg/m2 (p = 0.03), absence of preoperative biliary stenting (p = 0.009), and serum albumin < 36 g/L (p = 0.009) all correlated with receiving postoperative NS. Among those who did not develop a serious postoperative complication, i.e., those who had a relatively uneventful recovery, 20% received PN. Conclusions A considerable number of patients who had an uneventful recovery received PN. PN is not without risk, and should be reserved for those who are unable to take an oral diet. PD patients should undergo pre- and postoperative assessment by nutrition professionals to ensure they are managed appropriately, and to optimize perioperative outcomes.
