Recurrent peritoneal carcinomatosis in the scrotum in a patient with a history of mucocele of the appendix.

Paratesticular metastases are rare entities and a paratesticular metastasis of a mucinous appendiceal adenocarcinoma with peritoneal carcinomatosis has not been reported in the literature in the last 15 years. We present a case of mucinous appendiceal adenocarcinoma that progressed to peritoneal carcinomatosis. Twenty months following surgery and intraperitoneal therapy, the patient presented with testicular pain and swelling.

Angiofollicular lymphoid hyperplasia (Castleman disease) presenting as an isolated neck mass.

Castleman disease is a relatively uncommon lymphoproliferative disorder. A presentation as an isolated lesion in the neck is extremely rare. We report the case of a 26-year-old man who presented with a 4-month history of an enlarging right neck mass that was identified as Castleman disease on excisional biopsy.

Pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS): an indication for tonsillectomy.

Children with obsessive compulsive disorder or tic disorders that are associated with streptococcal infections (Group A beta-hemolytic) in the oro-pharyngeal region are given the diagnosis of pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS). Tonsillectomy has been reported to resolve the neuro-psychiatric symptoms in these children. We have a case of a 9-year-old boy who was seen in our clinic with multiple recurrent streptococcal infections of the oro-pharyngeal cavity.

Imaging findings in pediatric type 1 Gaucher disease: what the clinician needs to know.

This study presents visceral and skeletal imaging findings commonly observed in pediatric patients with type I Gaucher disease. Presented images show methods used for radiologic assessment of pediatric Gaucher patients, and imaging findings are discussed in the context of the underlying pathophysiology of the disease. Routine radiologic surveillance plays a central role in assessing Gaucher disease progression and response to treatment, but monitoring of pediatric patients presents specific challenges with regard to minimizing radiation exposure and interpreting extent of marrow involvement against the backdrop of normal growth-related changes in marrow composition.

Rare combination of frontonasal and bilateral naso-orbital encephaloceles.

Encephaloceles, while a common entity affecting 1:4000 live births, typically occur in the occipital region. Encephaloceles involving the frontal region comprise only 15% of all cases. Naso-orbital encephaloceles are rarely seen.

Ectopic nasopharyngeal pituitary adenoma resected with endoscopic technique.

We describe the case of an 80-year-old man with diabetes who presented with nonspecific dizziness. He was found on magnetic resonance imaging to have a 3.2-cm mass within the posterior and central aspect of the nasopharynx.

Isopentenyl pyrophosphate-activated CD56+ {gamma}{delta} T lymphocytes display potent antitumor activity toward human squamous cell carcinoma.

Purpose: The expression of CD56, a natural killer cell-associated molecule, on alphabeta T lymphocytes correlates with their increased antitumor effector function. CD56 is also expressed on a subset of gammadelta T cells. However, antitumor effector functions of CD56(+) gammadelta T cells are poorly characterized.

Paranasal sinus osteomas and Gardner's syndrome.

Objectives: Osteomas are common benign tumors of the paranasal sinuses. The origin of these lesions is uncertain. Although most are asymptomatic, symptoms can include headaches, facial pain, rhinorrhea, and sinusitis.

Adenomyomatous hyperplasia of the gallbladder with perineural invasion: revisited.

We report 9 examples of segmental adenomyomatous hyperplasia of the gallbladder with perineural invasion. Five patients were women and 4 men. Their ages ranged from 49 to 81 years (mean age 64 y).

Comparison of performance characteristics between new and reprocessed electrophysiology catheters.

Objective: Electrophysiology (EP) catheter reprocessing is widespread and previous studies have examined clinical performance, sterility and safety of these reprocessed devices. Here we compare the intrinsic engineering characteristics, electrical, mechanical and safety, between new and reprocessed devices.

Materials And Methods: New (58 devices) and clinically used (five times)/reprocessed (165 devices) EP catheters from five manufacturers were employed to examine and compare catheter electrode continuity, electrode isolation, electrical leakage current, shaft torsion and stiffness characteristics as well as tip buckling and bond strengths.

Microduplication 22q11.2, an emerging syndrome: clinical, cytogenetic, and molecular analysis of thirteen patients.

Chromosome 22, particularly band 22q11.2, is predisposed to rearrangements due to misalignments of low-copy repeats (LCRs). DiGeorge/velocardiofacial syndrome (DG/VCFS) is a common disorder resulting from microdeletion within the same band.
