Two foreign bodies embedded in the intraventricular septum: A case report
A 23-year old male was presented at the outpatient clinic of our department reporting that he had been subjected to insertion of foreign bodies in his chest. Physical examination was unremarkable. Imaging studies revealed the presence of two bodies in the subcutaneous tissue of the anterior chest wall and two needle-shaped intramyocardial bodies that were impacted in the intraventricular septum. Due to late appearance, the position, and because of the absence of symptoms, it was decided that the patient should be managed conservatively. Today, five years after the incident, the patient remains asymptomatic and he is followed-up regularly
Correlation between mesenteric fat thickness and serum apolipoproteins in patients with peripheral arterial occlusive disease
BACKGROUND: Visceral fat possesses the most detrimental potential for cardiovascular morbidity through the release of adipokines, as well as metabolic and proinflammatory mediators, which adversely affect metabolic and vascular homeostasis. Among the different types of visceral adipose tissue, mesenteric fat is considered particularly detrimental, due to its close proximity to the portal circulation, affecting directly the liver, which is the main regulator of body metabolic homeostasis. Mesenteric fat can be reliably estimated using abdominal ultrasonography, the only available imaging method able to depict individual mesenteric leaves. Aim of the present study was to investigate the correlation of mesenteric fat thickness (MFT) with serum apolipoprotein levels in patients undergoing digital subtraction angiography in a single center. METHODS: 35 male patients with peripheral arterial disease were examined. After careful examination of the periumbilical area, the mesenteric leaves were identified. The maximal distance between each pair of sequential leaves was measured, and the mean value of the three thickest leaves was determined as the mesenteric fat thickness. Six apolipoprotein fasting serum concentrations were measured using a Luminex proteomics platform (xMAP Multiplex immunoassay): apolipoprotein A-I (apoAI), apolipoprotein A-II (apoAII), apolipoprotein B (apoB), apolipoprotein C-II (apoCII), apolipoprotein C-III (apoCIII) and apolipoprotein E (apoE). RESULTS: MFT correlated with apoAII and apoB serum concentrations. The correlations with apoAII and apoB remained significant following correction for BMI. No correlations were noted between MFT and serum apoAI, apoCII, apoCIII or apoE levels before or after adjustment for BMI. CONCLUSIONS: Our study indicates that MFT is significantly correlated with the concentration of atherogenic low density lipoproteins particles, as well as with apoAII, a determinant of free fatty acids levels. No correlation was observed between mesenteric fat thickness and very low density lipoprotein or chylomicron particles concentration
Should Diaphragmatic Involvement Preclude Resection of Large Hepatic Tumors?
Treatment of peripherally located liver tumors with diaphragmatic
invasion is technically demanding but does not preclude resection for
cure. The aim of the present study was to compare patients undergoing
combined liver and diaphragmatic resection with those submitted to
hepatectomy alone so as to evaluate the safety, effectiveness, and value
of this complex surgical procedure.
From January 2000 to September 2011, 36 consecutive patients underwent
en bloc liver-diaphragm resection (group A). These were individually
matched for age, gender, tumor size, pathology, and co-morbitidies with
36 patients who underwent hepatectomy alone during the same time (group
B). Operative time, warm ischemia time, blood loss, required
transfusions, postoperative complications, and long-term survival were
evaluated.
Mean operative time was significantly longer in group A than in group B
(165 vs 142 min; P = 0.004). The two groups were comparable regarding
warm ischemia time, intraoperative blood loss, required transfusions,
and postoperative laboratory value fluctuations. Some 33 % of group A
patients developed complications postoperatively as opposed to 23 % of
group B patients (P = 0.03). The mortality rate was 2.8 % in group A
compared to 0 % in group B. Postoperative follow-up demonstrated 60 %
1-year survival for group A patients as opposed to 80 % 1-year survival
for group B patients, a difference that is practically eliminated the
longer the follow-up period is extended (35 vs 40 % 3-year survival and
33 vs 37 % 5-year survival for group A and group B patients,
respectively).
En bloc diaphragmatic and liver resection is a challenging but safe
surgical procedure that is fully justified when diaphragmatic
infiltration cannot be ruled out and the patient is considered fit
enough to undergo surgery
Heart dysfunction induced by choline-deficiency in adult rats: The protective role of L-carnitine
Choline is a B vitamin co-factor and its deficiency seems to impair
heart function. Carnitine, a chemical analog of choline, has been used
as adjunct in the management of cardiac diseases. The study investigates
the effects of choline deficiency on myocardial performance in adult
rats and the possible modifications after carnitine administration.
Wistar Albino rats (n=24), about 3 months old, were randomized into four
groups fed with: (a) standard diet (control-CA), (b) choline deficient
diet (CDD), (c) standard diet and carnitine in drinking water 0.15% w/v
(CARN) and (d) choline deficient diet and carnitine (CDD+CARN). After
four weeks of treatment, we assessed cardiac function under isometric
conditions using the Langendorff preparations [Left Ventricular
Developed Pressure (LVDP-mmHg), positive and negative first derivative
of LVDP were evaluated], measured serum homocysteine and brain
natriuretic peptide (BNP) levels and performed histopathology analyses.
In the CDD group a compromised myocardium contractility compared to
control (P=0.01), as assessed by LVDP, was noted along with a
significantly impaired diastolic left ventricular function, as assessed
by (-) dp/dt (P=0.02) that were prevented by carnitine. Systolic force,
assessed by (+) dp/dt, showed no statistical difference between groups.
A significant increase in serum BNP concentration was found in the CDD
group (P<0.004) which was attenuated by carnitine (P<0.05), whereas
homocysteine presented contradictory results (higher in the CDD+CARN
group). Heart histopathology revealed a lymphocytic infiltration of
myocardium and valves in the CDD group that was reduced by carnitine. In
conclusion, choline deficiency in adult rats impairs heart performance;
carnitine acts against these changes. (C) 2013 Elsevier B.V. All rights
