Neurilemmoma of tongue

Neurilemmoma is usually soimry, benign tumour derived from schwan cells of the Sheaths of peripheral cranial or autonomie nerves. In thehead and neck region it occurs most commonly in association with acoustic nerve within the skuil and is rely fottnd in the oral cavity (1,2). We report here two cases of the iongue diagnosed on histopathohgy.     

Verrucous carcinoma of larynx

A 55 years male presented with hoarsness of voice (4 months), cough (1 month), difficulty in breathing (15 days). Patient underwent an emergency tracneostomy and further workup proved it to be a case of verrucous carcinoma of larynx. Patient was treated surgically with satisfactory result.     

Effect of QT interval prolongation on cardiac arrest following liver transplantation and derivation of a risk index

Liver transplantation (LT) has a 4-fold higher risk of periprocedural cardiac arrest and ventricular arrhythmias (CA/VAs) compared with other noncardiac surgeries. Prolongation of the corrected QT interval (QTc) is common in patients with liver cirrhosis. Whether it is associated with an increased risk of CA/VAs following LT is unclear. Rates of 30-day CA/VAs post-LT were assessed in consecutive adults undergoing LT between 2010 and 2017. Pretransplant QTc was measured by a cardiologist blinded to clinical outcomes. Among 408 patients included, CA/VAs occurred in 26 patients (6.4%). QTc was significantly longer in CA/VA patients (475 ± 34 vs 450 ± 34 ms, P < .001). Optimal QTc cut-off for prediction of CA/VAs was ≥480 ms. After adjustment, QTc ≥480 ms remained the strongest predictor for the occurrence of CA/VAs (odds ratio [OR] 5.2, 95% confidence interval [CI] 2.2-12.6). A point-based cardiac arrest risk index (CARI) was derived with the bootstrap method for yielding optimism-corrected coefficients (2 points: QTc ≥480, 1 point: Model for End-Stage Liver Disease [MELD] ≥30, 1 point: age ≥65, and 1 point: male). CARI score ≥3 demonstrated moderate discrimination (c-statistic 0.79, optimism-corrected c-statistic 0.77) with appropriate calibration. QTc ≥480 ms was associated with a 5-fold increase in the risk of CA/VAs. The CARI score may identify patients at higher risk of these events. Whether heightened perioperative cardiac surveillance, avoidance of QT prolonging medications, or beta blockers could mitigate the risk of CA/VAs in this population merits further study.     

Long-Term Outcomes of Endovascular Interventions in More than 500 patients with Budd–Chiari Syndrome

PurposeTo assess and compare the long-term outcomes of various endovascular interventions in patients with Budd-Chiari syndrome (BCS).Materials and MethodsIn this single-center retrospective study, 510 consecutive patients with BCS who had undergone a total of 618 endovascular procedures from January 2001 to December 2019 were included. Details of the type of endovascular intervention, technical success, clinical success, patency rate, complications, and survival outcomes were analyzed.ResultsThe overall technical success rate was 96% (593 of 618 procedures; 500 in treatment-naïve patients and 93 repeat interventions for recurrent disease). Endovascular procedures included recanalization procedures (angioplasty and stent placement) in 355 patients (71%) and transjugular intrahepatic portosystemic shunt (TIPS) creation in 145 (29%). Major postprocedure complications occurred in 14 patients (2.8%). Vascular/stent restenosis occurred in 95 patients (19%), and successful repeat intervention was performed in 82 of those 95 (86.3%). An additional 11 of these 82 (13.4%) underwent a third intervention for restenosis. In the recanalization and TIPS groups, the 1- and 5-y cumulative patency rates were 87% and 74% and 95% and 68%, respectively. The 1- and 5-y survival rates were 96% and 89% and 90% and 76%, respectively.ConclusionsEndovascular interventions for BCS are feasible and safe in the majority of patients, with excellent short- and long-term patency and survival rates.     

Normal Anatomic Variants on Transthoracic Echocardiogram

Apart from their existence as medical curiosities, anatomic variants also double as diagnostic dilemmas. In the heart, more than in any other location in the body, misinterpretation of normal anatomic variants as pathologic entities can have a profound impact on treatment decisions and clinical consequences. Echocardiography is an easily accessible tool these days and is used routinely in most cardiac evaluations. Thus it becomes imperative for the echocardiographer to be cognizant of normal anatomic variants. Furthermore, echocardiographic findings should always be evaluated in their proper clinical context and diagnoses should never be entertained in a clinical vacuum. The literature is replete with numerous case reports and vignettes on these fascinating structures but is lacking in a formal review of normal anatomic variants. In this article, we have attempted a systemic review of normal variants, their embryologic origins, echocardiographic characteristics, and common pitfalls encountered in their evaluation.     

Relationship between white blood cell count and incident hypertension

BACKGROUND: Elevated white blood cell (WBC) count is considered to be prospectively associated with cardiovascular disease. However, its relationship to hypertension, independent of smoking and other established cardiovascular risk factors, is not clear, especially among women. METHODS: We used data from a large population-based study in Wisconsin (Beaver Dam Eye study) to examine the prospective association between elevated WBC count and incident hypertension among 2459 hypertension-free women (48.6%) and men (51.4%) after adjusting for, and stratifying by smoking and several other potential confounding factors. RESULTS: In multivariable proportional hazards models, increasing tertiles of WBC count was associated with increased risk ratios (RR) of hypertension in the whole cohort (WBC count tertiles 1-3; RR 1, 1.2, 1.7; P <.01), and separately among women (WBC count tertiles 1-3; RR 1, 1.1, 1.4; P <.05) and men (WBC count tertiles 1-3; RR 1, 1.3, 1.9; P <.01). Results from subsequent analyses stratified by smoking and several other related factors were consistent with this finding. CONCLUSIONS: Elevated WBC count is associated with incident hypertension among women and men independent of smoking and most traditional cardiovascular risk factors in this predominantly white cohort. Further research is required to determine whether this association is true among racial minorities (eg, African Americans), and independent of C-reactive protein, a more specific marker of inflammation.
