Harmonic Scalpel and Electrothermal Bipolar Vessel Sealing System in Head and Neck Surgery: A Prospective Study on Tissue Heating and Histological Damage on Nerves.

Objectives: Define and compare the thermal nerve injury caused by 3 different vessel sealing and dissection devices: the harmonic scalpel (HS), the electrothermal bipolar vessel sealing system (EBVS), and the bipolar electrosurgery unit (BE).

Methods: First we recorded the heating variations in pig tissue caused by a BE unit, HS, and EBVS after an activation for 5, 10, and 15 seconds at minimum and at maximum power. In the second part, we evaluated the histological damage caused by HS and EBVS on 20 in vivo human nerves, 10 per device.

Cutaneous pseudolymphoma following tattoo application: report of two new cases of a potential lymphoma mimicker.

The authors report 2 cases of cutaneous pseudolymphoma that occurred in 2 young adult patients who referred for relentlessly growing nodules that appeared within 4 to 5 months after the application of a mercury-based tattoo. Systemic symptoms were not present and there was no evidence of lymph node enlargement. Clinically, both lesions were limited to the red, mercury-based areas of the tattoo.

Intravesical botryoid adenocarcinoma of the prostate: report of an unusual growth pattern of prostatic carcinoma simulating a urinary bladder tumor.

We report on 3 cases of prostatic carcinoma presenting with a predominant intravesical mass as to simulate clinically and macroscopically a primary tumor of the urinary bladder. The patients were 65, 66, and 68 years old and presented with dysuria and micturition. All patients had a medical history of a prostatic adenocarcinoma diagnosed between 5 and 7 years earlier and treated conservatively.

Russell body gastritis: expanding the spectrum of Helicobacter pylori - related diseases?

We report a new case of Helicobacter pylori gastritis showing plasma cell infiltrates with extensive formation of Russell bodies (Mott cells) within the lamina propria of the antral mucosa. The patient was a 60-year-old woman with a history of epigastric pain. Endoscopy revealed non-specific congestion of the mucosa.

Chance diagnosis of low stage non-metastasized adrenal cortical carcinoma in a young woman with retroperitoneal hemorrhage.

Adrenal cortical carcinoma (ACC), a rare and highly malignant neoplasm of the cortical tract of the adrenal gland, is usually diagnosed at an advanced stage of development and often when metastatic spread already has begun. We report a very rare case of low-stage, non-metastasized ACC, the first clinical appearance of which was a large retroperitoneal hemorrhage caused by the rupture of the neoplastic mass. To the best of our knowledge, this is the third reported case of ACC rupture.

Extensive metastatic leptomeningeal melanomatosis as the first clinical sign of a cutaneous melanoma: morphological correlations between magnetic resonance imaging and autopsy findings. A case report.

In recent years, the diagnosis and management of leptomeningeal carcinomatosis have gained increased attention as patients with neoplasms live longer and the condition becomes more common. Conclusive hallmarks of this disease have yet to be identified. We report and discuss a case of massive invasion of the cerebral leptomeninges by neoplastic cells from a malignant melanoma in a shoulder.

Increased myocardial apoptosis in patients with unfavorable left ventricular remodeling and early symptomatic post-infarction heart failure.

Objectives: The purpose of this study was to evaluate a potential correlation between apoptotic rate (AR), post-infarction left ventricular (LV) remodeling, and clinical characteristics in subjects who died late (>or=10 days) after an acute myocardial infarction (AMI) with evidence of persistent occlusion of the infarct-related artery at autopsy.

Background: Apoptosis contributes to myocardiocyte loss in cardiac disease and may have a pathophysiologic role in post-infarction LV remodeling.

Methods: The AR was calculated at the site of infarction and in remote unaffected LV regions, using co-localization of in situ end labeling for deoxyribonucleic acid fragmentation and immunohistochemistry for caspase-3, in 14 subjects who died within two months after AMI.
