In this study, level IIb lymph node metastasis was only found in association with tongue carcinoma. Although this region may be preserved in elective SOHND in patients with SCC of the oral cavity, it should be included whenever the tongue is the primary site.

Objectives: It was the aim of this study to determine whether level IIB lymph nodes can be saved in elective neck dissection as a treatment for patients with squamous cell carcinoma (SCC) of the larynx. We present a prospective analysis of a case series. Methods: Thirty-one patients with SCC of the larynx and without palpable lymph nodes at the neck who underwent an elective neck dissection were prospectively studied. The incidence of micrometastasis to level IIB lymph nodes after performing elective neck dissection was evaluated by nested reverse transcription polymerase chain reaction for cytokeratin (CK)19 and CK20 as well as by pathological examination. Results: Nested reverse transcription polymerase chain reaction for CK19 and CK20 mRNA presented similar results but differed from the pathological examination. Of the 31 patients, 6 (19%) by pathological analysis and 9 (29%) by molecular analysis had lymph nodes positive for metastatic SCC. By molecular analysis, only 1 of the 31 patients had involvement of level IIB lymph nodes. Conclusions: This region may be preserved in elective neck dissection in patients with SCC of the larynx, so that accessory nerve dysfunction can be minimized and operative time can be saved.

This study suggests the Doppler sonography as a non-invasive, low-cost, and readily available tool for the evaluation and follow-up of articular involvement in knees of JIA patients.

Background: Among patients with ST-segment Elevation Myocardial Infarction (STEMI) undergoing primary Percutaneous Coronary Intervention (PCI), worsening of renal function resulting in Acute Kidney Injury (AKI) is a frequent complication known to be associated with adverse outcomes. Also, anemia on admission is associated with an increased risk for (AKI). The relation between echocardiographic parameters of Left Ventricular (LV) function and the risk of AKI among patients with STEMI undergoing PCI is still controversial. Aim of the Study: Detection of the relationship between hemoglobin level and LV systolic and diastolic function as a predictors for developing AKI after primary PCI in patients with STEMI.
