Trends and Outcomes of Hospitalizations Due to Hemolytic Uremic Syndrome: A National Perspective.

Background: Hemolytic uremic syndrome (HUS) is a rare but challenging disease with varying degrees of mortality and prognosis. We aim to evaluate the trends and outcomes of hospitalizations due to HUS by utilizing a large population-based dataset.

Methods: We derived a study cohort from the Nationwide Inpatient Sample (NIS) for the years 2007-2018.

Computerized tomography based tumor-thickness measurement is useful to predict postoperative pathological tumor thickness in oral tongue squamous cell carcinoma.

Background: Tumor thickness has been shown in oral tongue squamous cell carcinoma (OTSCC) to be a predictor of cervical metastasis. The postoperative histological measurement is certainly the most accurate, but it would be of clinical interest to gain this information prior to treatment planning. This retrospective study aimed to compare the tumor thickness measurement between preoperative, CT scan, and surgical specimens .

Clinical parameters predicting development of pulmonary malignancies in patients treated for head and neck squamous cell carcinoma.

Background: As the locoregional control rates in head and neck squamous cell carcinoma (HNSCC) have increased, these patients may suffer distant metastasis in a higher proportion of cases. Clinicopathological characteristics allowing prediction of high-risk profile would allow adapting posttreatment surveillance to individual risk.

Methods: A retrospective review of all patients with HNSCC treated at the Jewish General Hospital, McGill University, Montreal, Quebec, Canada, between 1999 and 2008 was conducted for this study.

Laryngotracheal rhinosporidiosis.

Rhinosporidiosis is a chronic granulomatous disease caused by Rhinosporidium seeberi. It usually affects mucous membranes of the nose, nasopharynx, and ocular conjunctiva. Cutaneous, laryngeal, tracheal, genital, and bony dissemination is rare.

Development of hemangioma in a tongue harboring long-standing angiokeratoma circumscriptum.

Angiokeratoma is a very rare vascular lesion of the papillary dermis. It is characterized by vascular ectasia with overlying epidermal hyperkeratosis. The systemic form of angiokeratoma is associated with Fabry disease and fucosidosis.
