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.

Embryogenic cervico-thyro-piriform tract.

Branchial cleft fistulae are rare congenital anomalies that arise from the abnormal persistence of branchial remnants. Branchial arch anomalies are rare. They usually present as a lateral neck mass or abscess in the form of acute suppurative thyroiditis.

Giant tracheocele with multiple congenital anomalies.

Tracheocele--an outpouching of tracheal mucous membrane--is an uncommon entity. It can occur as a congenital or acquired form. The congenital entity remains mostly dormant until adulthood, and then it typically presents as a herniation with multiple air-filled sacs.

Primary extranodal T-cell non-Hodgkin lymphoma of the tongue.

The most common sites of extranodal non-Hodgkin lymphoma (NHL) are the gastrointestinal tract and the head and neck region. Head and neck involvement accounts for 8 to 13% of all extranodal lymphomas. Primary NHLs of the oral cavity, especially in the tongue, are extremely rare, which makes it difficult to understand their biologic behavior.

Primary frontal sinus carcinoma with extradural anterior cranial fossa involvement.

Paranasal sinus carcinoma is rare, with an estimated annual incidence of less than 1 per 100,000 population. Primary frontal sinus involvement is extremely rare, accounting for only 0.3% of all paranasal sinus malignancies.

Recurrent neck infection with branchial arch fistula in children.

Objective: Acute suppurative neck infections associated with third or fourth branchial arch fistulas are frequently recurrent. Third and fourth branchial arch anomalies are much less common than those of second arch and usually present with left thyroid lobe inflammation. The authors present their experience with 15 cases of pyriform sinus fistulae (PSF) of third branchial arch origin and 3 cases of fourth arch origin, all of which presented as recurrent neck infection mainly on the left side.

Microbiological profile with antibiotic sensitivity pattern of cholesteatomatous chronic suppurative otitis media among children.

Introduction: Chronic suppurative otitis media (CSOM) is the most common cause of childhood hearing impairment in the developing countries and atticoantral type is associated with increased incidence of intracranial and extracranial complications. This study was undertaken to define the microbiology of atticoantral type of chronic otitis media and the antibiotic sensitivity pattern, thereby reducing the potential risks of complications.

Materials And Methods: A retrospective study was done in the Department of Otolaryngology, JIPMER, Puducherry from the year August 2003 to October 2009 using the medical record department database to retrieve the patient details.

Longstanding malformation of right sided pinna in an elderly man.

The pinna is the second most common site for external ear vascular malformation in the head and neck. These malformations are relatively uncommon in adults and can pose difficult therapeutic challenges. We hereby present a case of a 69-year-old man with a congenital lesion in the right pinna consistent with an arteriovenous malformation.

Cervical infection secondary to pyriform sinus fistula of branchial origin.

Complete third branchial arch anomalies are rare and have been described only in case reports, affecting mainly children and typically presenting as a cervical inflammatory process. Anomalies of the third and fourth branchial apparatus, though rare, usually present as sinuses/incomplete fistulas of pyriform sinus or recurrent suppurative thyroiditis. A 6-year-old girl presented with a small opening on the left side of her anterior neck, which had been present since birth and was associated with recurrent infection.

Giant congenital auricular arteriovenous malformation.

Arteriovenous malformation (AVM) is an uncommon vascular anomaly usually present in intracranial location, however may be present in other sites of the body, mostly in the head and neck region. The lesion may be present since birth or caused by trauma, but may become obvious during puberty or pregnancy. The diagnosis can be confirmed by selective angiography.

True thyroglossal fistula.

Thyroglossal duct anomalies are the most common malformations in the neck and constitute 70% of all the congenital cervical masses. They are more common in the pediatric population under 5 years of age, and 60% of lesions are diagnosed before the age of 20. They represent remnants from the embryological migration of thyroid tissue from foramen caecum to the thyroid fossa.

Hypohidrotic ectodermal dysplasia with atrophic rhinitis and nasal myiasis.

Hypohidrotic/anhidrotic ectodermal dysplasia is a rare inherited disorder characterized by hypohidrosis/anhidrosis, hypotrichosis, dysodontia and heat intolerance. Most common mode of transmission is X-linked recessive, showing complete expression in males, and only partial manifestations in the female carrier heterozygotes. Features like atrophic rhinitis, nasal and aural myiasis, syndactyly, cleft lip and/or palate, mental retardation and immunodeficiency are uncommonly seen in this syndrome.
