Large retrorectal spindle cell sarcoma: A case report and brief review of the literature.

Large retrorectal tumors are rare and often a diagnostic and surgical challenge due to their anatomical location. We report the case of a 55-year-old patient with weight loss and changed bowel habits, where digital rectal examination revealed a retrorectal mass raising suspicion of a tumor. Magnetic resonance imaging (MRI) and computed tomography (CT) showed a large retrorectal tumor and histopathology after surgical resection showed undifferentiated spindle cell sarcoma. This tumor type has not been previously reported as the etiology of large retrorectal tumors. We discuss the implications of diagnostic imaging, especially MRI, in the approach to diagnosis and surgical treatment of retrorectal tumors with reference to the scientific literature and previously reported cases of retrorectal tumors.

Risk of Stroke and Myocardial Infarction Among Initiators of Triptans.

Importance: Triptans are contraindicated in patients with ischemic heart disease or previous myocardial infarction, and caution is advised when prescribing these drugs to patients with vascular risk factors. However, controlled observational studies have either shown no association or an apparent lower risk, possibly owing to a channeling of triptans to individuals at low risk of cardiovascular outcomes, and it remains unclear whether avoiding triptan treatment for these patients is meaningful. Objective: To establish whether an association between triptans and ischemic events could be demonstrated using a self-controlled design because this type of design is robust to the previously mentioned type of confounding. Design, Setting, and Participants: All people in nationwide Danish registries who were initiating triptans and all the ischemic events that they experienced were identified. A case-crossover design was used to estimate odds ratios (OR) for associations between first-ever triptan use and ischemic outcomes, comparing triptan exposure in the 2-week period up to the event with four 2-week reference periods. Data were obtained for the period January 1995 to August 2022. Included from the population of Denmark were individuals redeeming a prescription for any triptan and experiencing at least 1 of 3 predefined ischemic outcomes. No one was excluded. Exposure: Initiation of any triptan. Main Outcomes and Measures: Acute myocardial infarction, ischemic stroke, or nonspecified stroke. Results: Identified were a total of 429 612 individuals (median [IQR] age, 38 [28-48] years; 325 687 female [75.8%]) who redeemed a first prescription for a triptan in the study period. Of these patients, 11 (0.003%) had a myocardial infarction with the first triptan prescription in either a focal or referent window (odds ratio [OR], 3.3; 95% CI, 1.0-10.9), 18 (0.004%) had ischemic stroke (OR, 3.2; 95% CI, 1.3-8.1), and 35 (0.008%) had ischemic/nonspecified stroke (OR, 3.0; 95% CI, 1.5-5.9). Case patients had a median age of approximately 60 years and had a high-risk cardiovascular profile. Conclusions and Relevance: Results of this case-crossover study suggest that triptan initiation was associated with higher risk of ischemic stroke and myocardial infarction. For the individual patient with low background cardiovascular risk, the risk of an ischemic event after triptan initiation was very low.

Spermatocytic tumors in 2 patients aged 50 and 77 years: 2 case reports and brief review of the literature.

Testicular cancer is predominantly diagnosed in young men aged 15-35 years. However, there are some rare tumors such as spermatocytic tumors that are seen more often in the older male population. Spermatocytic tumors have previously been known as spermatocytic seminomas in the scientific literature. We report the cases of 2 patients aged 50 and 77 years both diagnosed with spermatocytic tumors. In this paper we will discuss the ultrasound and histopathology features of these tumors and review the literature of spermatocytic tumor cases.

Intrauterine hormonal contraception and risk of breast cancer.

Intrauterine hormonal contraception devices are widely used among Danish women. Cases of breast cancer have been reported in women using the devices and studies have found evidence of an increased risk, but a new meta-analysis did not find an increased risk. The reported relative risks in some of the studies are numerically substantial as quoted in this review, but it is very important that physicians take absolute numbers into account when interpreting risk in order to provide the best guidance of patients with regard to contraception and associated risks.

Hemoptysis with no malignancy suspected on computed tomography rarely requires bronchoscopy.

Background: Hemoptysis is an alarming and common symptom leading to thorough diagnostic evaluation with computed tomography and fiberoptic bronchoscopy. Increasing evidence suggests that bronchoscopy is not necessary in diagnosing lung cancer in hemoptysis patients because of high sensitivity of computed tomography. However, less attention has been paid to non-malignant etiologies of hemoptysis. Objective: We aimed to identify the etiologies established in hemoptysis patients with no malignancy suspected on computed tomography in order to assess the necessity of bronchoscopy in these patients. Design: We retrospectively reviewed clinical records of consecutive patients referred to evaluation for hemoptysis with no malignancy suspected on computed tomography at Aalborg University Hospital, Denmark, in an eleven-year period from 2006 to 2016. Results: One thousand one hundred and eighty-five patients (mean age 57.5 ± 15.44 years, 61.3% male) were included in the study. Bronchoscopy was performed in 91.9% of cases. Most patients (83.5%) had cryptogenic hemoptysis, while the most frequently identified etiologies were respiratory tract infection (12.6%) and bronchiectasis (2.2%). No patients had malignant disease as their etiology. Conclusions: The vast majority of hemoptysis cases with no malignancy suspected on computed tomography were cryptogenic and all were benign. Bronchoscopy may be reserved for patients with specific conditions suspected and those with persistent symptomatology.

Five-year follow-up of hemoptysis with no malignancy suspected on chest computed tomography: recurrence, lung cancer and mortality.

Background: Evidence from recent years suggests most cases of hemoptysis to be caused by non-malignant etiologies, but the long-term outcome for these patients has been less thoroughly investigated. Objective: We aimed to assess the rates of hemoptysis recurrence, new lung cancer diagnoses and death within 5 years of initial referral for hemoptysis. Design: In this retrospective study, we reviewed clinical records of consecutive patients referred to evaluation for hemoptysis with no malignancy suspected on chest computed tomography at Aalborg University Hospital, Denmark, in a seven-year period from 2006 to 2012. Results: A total of 609 patients (mean age 56.7 ± 14.1 years, 60.6% male) were included in the study. The etiology was cryptogenic in 81% of patients and no patients had malignant disease. In the following 5 years, lung cancer developed in 1.5% of patients. Median time to diagnosis was 26 (IQR 18-33) months. Nine percent of patients had at least one recurrence of hemoptysis, and the 5-year mortality rate was 12% with median time to death 31 (IQR 13-43) months. Conclusions: Lung cancer developed in less than 2% within 5 years after referral for hemoptysis with no malignancy suspected on chest computed tomography. Further research is needed to identify risk factors for the development of lung cancer in these patients.

Thresholds for Oxford Knee Score after total knee replacement surgery: a novel approach to post-operative evaluation.

BACKGROUND: In a prospective cohort study, we wanted to detect thresholds distinguishing between patients with a satisfactory and an unsatisfactory outcome after total knee replacement (TKR) based on Patient-Reported Outcome Measures (PROMs), namely the Oxford Knee Score (OKS), using patient satisfaction and patient-perceived function as global transition items. METHODS: Seventy-three TKR patients completed the OKS questionnaire before surgery and were invited to complete the same questionnaire again 6 (4 to 9) months after surgery. Correlations between outcome measures and anchors were calculated using Pearson's correlation coefficient. Thresholds were established by receiver operating characteristics (ROC) analysis, using multiple anchor-based approaches. RESULTS: Patients showed a mean increase of 16.5 (SD 9.5) in OKS following TKR. Significant positive correlations were found between outcome measures and anchors. Six different thresholds were determined for outcome measures coupled with satisfaction, patient-perceived function and a combination thereof using a cut-off of 50 and 70. CONCLUSIONS: This study has established a set of clinically meaningful thresholds for Oxford Knee scores that may help to detect TKR patients who might be in need of post-operative evaluation.
