Laparoscopy or laparotomy for the management of endometrial cancer.

OBJECTIVE: The aim of this study was to evaluate the feasibility of laparoscopy in the management of early stage endometrial cancer. METHODS: Fifty-two patients with endometrial cancer who underwent surgical staging consisting of total hysterectomy, bilateral salpingo-oophorectomy with pelvic lymph node dissection, and cytology between 1998 to 2002 were included in the study. Laparotomy and laparoscopy were randomly offered to patients upon admittance. RESULTS: Of 52 patients, 26 underwent laparotomy and the remaining 26 underwent laparoscopic staging surgery. No significant difference existed between the demographic characteristics of the 2 groups. The mean number of harvested lymph nodes was 18.2 in the laparoscopic group and 21.1 in the laparotomic group (P>0.05). Pelvic lymph node metastases were detected in 7.7% of the patients in the laparoscopy group and 15.4% in the laparotomy group, and the difference was not significant. Adjuvant radiotherapy was applied later to 42.3% of the laparoscopy group and 38.5% of the laparotomy group. Operative morbidity was higher in the laparotomy group mainly because of postoperative wound infection, and the patients in the laparotomy group had a longer hospital stay. CONCLUSION: Laparoscopic surgery is a method that can be applied as well as laparotomy in the management of endometrial cancer. Lymph node number and detection of lymph node metastasis did not differ significantly in laparotomic and laparoscopic approaches. Wound infections were more frequent in laparotomies.     

Early impact of hormone replacement therapy on vascular hemodynamics detected via ocular colour Doppler analysis

Objective: To determine the effects of hormone replacement therapy (HRT) on ocular blood flow.

Study design: In a prospective controlled study, 40 healthy women who presented to the menopause clinic between December 2000 and December 2001 were randomly assigned into the study. The HRT-receiving group was administered estradiol 17-valerate 2 mg the first 11 days, and estradiol 17-valerate 2 mg plus ciproterone acetate 1 mg the next 10 days of the monthly cycle for 6 months. The control group did not receive any HRT for 6 months. The ocular colour Doppler analysis were performed at baseline and after 3 and 6 months. The ocular Doppler analysis was performed in the first half of the cycle in the HRT-receiving group.

Results: Central retinal artery and ophthalmic artery basal Doppler index (peak systolic velocity, end-diastolic velocity, resistive index and pulsatility index) values of the two groups at the beginning of the study did not show any statistically significant difference. Both the right and the left central retinal artery pulsatility index (PI) values of the study group, who received HRT at the end of the third and sixth months, showed a statistically significant decline (paired-samples test, P < 0.05), while the decrease in the resistive indexes was not significant.

Conclusion: These results suggest that 6 months of combined hormone replacement therapy with estradiol 17-valerate 2 mg plus ciproterone acetate 1 mg improves ocular vascular Doppler indices which may be a reflection of cerebral vascular status.     

Constitutive activation of the PI3K‐AKT pathway and cardiovascular abnormalities in an individual with Kosaki overgrowth syndrome

Kosaki overgrowth syndrome is a recently described syndrome characterized by distinctive facial features, brain white matter lesions, and developmental delay. Germline activating heterozygous PDGFRB mutations have been reported in this condition. Systemic connective tissue‐type findings have been described in some individuals. We describe a 19‐year‐old Caucasian female with a history of hydrocephalus, Dandy–Walker malformation, cervical spine arachnoid cyst, progressive scoliosis, and overgrowth. Her physical exam included distinctive craniofacial dysmorphism, as well as soft and hyperextensible skin. Cardiovascular imaging during adolescence revealed saccular aneurysms in both coronary artery systems and subtle tortuosity of the cervical vertebral arteries. Exome sequencing trio analysis identified a de novo previously reported pathogenic variant in PDGFRB, c.1696T>C (p.[Trp566Arg]). Further functional studies included platelet‐derived growth factor cellular metabolic pathway activity that confirmed the variant causes a constitutive activation of the PI3K‐AKT pathway. This is the first report to characterize the activating nature of this PDGFRB variant. We also highlight the connective tissue findings seen in Kosaki overgrowth syndrome and recommend baseline echocardiographic evaluation in all individuals with this condition with particular emphasis on coronary arteries.

The Factors Contributing to Death Anxiety in Cancer Patients

Suffering comes in many ways for patients confronting cancer. One of these is an unspecifiable fear about death, which is an existential issue. The aim of this study was to investigate the relationship between death anxiety and its correlates in cancer patients. Seventy cancer patients were assessed using SCID-I, Templer's Death Anxiety Scale, the Hospital Anxiety (A) and Depression (D) Scale, the Distress Thermometer, the Visual Analogue Scale for pain (VAS), the Global Assessment of Functioning, and Glock and Stark's Dimensions of Religious Commitment scales, and these assessments were compared between cancer patients with and without death anxiety. Multiple regression analysis was conducted after correlation analysis between death anxiety and sociodemographic and clinical variables. Axis I psychiatric diagnosis, pain scores, and negative believes about what will happen after death were found to be higher in patients having death anxiety than patients not having death anxiety. Also life expectancy was perceived as shortened in patients with death anxiety. Death anxiety was associated with anxiety, depressive symptoms, and beliefs about what will happen after death. In conclusion, death anxiety could not be regarded as a natural consequence of having cancer; it is associated with the unresolved psychological and physical distress.     

The interplay between metabolic alterations,diastolic strain rate and exercise capacity in mild heart failure with preserved ejection fraction: a cardiovascular magnetic resonance study

Background

Heart failure (HF) is characterized by altered myocardial substrate metabolism which can lead to myocardial triglyceride accumulation (steatosis) and lipotoxicity. However its role in mild HF with preserved ejection fraction (HFpEF) is uncertain. We measured myocardial triglyceride content (MTG) in HFpEF and assessed its relationships with diastolic function and exercise capacity.

Methods

Twenty seven HFpEF (clinical features of HF, left ventricular EF >50%, evidence of mild diastolic dysfunction and evidence of exercise limitation as assessed by cardiopulmonary exercise test) and 14 controls underwent ¹H-cardiovascular magnetic resonance spectroscopy (¹H-CMRS) to measure MTG (lipid/water, %), ³¹P-CMRS to measure myocardial energetics (phosphocreatine-to-adenosine triphosphate - PCr/ATP) and feature-tracking cardiovascular magnetic resonance (CMR) imaging for diastolic strain rate.

Results

When compared to controls, HFpEF had 2.3 fold higher in MTG (1.45?±?0.25% vs. 0.64?±?0.16%, p?=?0.009) and reduced PCr/ATP (1.60?±?0.09 vs. 2.00?±?0.10, p?=?0.005). HFpEF had significantly reduced diastolic strain rate and maximal oxygen consumption (VO₂ max), which both correlated significantly with elevated MTG and reduced PCr/ATP. On multivariate analyses, MTG was independently associated with diastolic strain rate while diastolic strain rate was independently associated with VO₂ max.

Conclusions

Myocardial steatosis is pronounced in mild HFpEF, and is independently associated with impaired diastolic strain rate which is itself related to exercise capacity. Steatosis may adversely affect exercise capacity by indirect effect occurring via impairment in diastolic function. As such, myocardial triglyceride may become a potential therapeutic target to treat the increasing number of patients with HFpEF.

     

Is multiple sclerosis a risk factor for atherosclerosis?

BackgroundMultiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system. We aimed to discuss possible predisposing factors to atherosclerosis such as carotid intima-media thickness (CIMT) and high-sensitivity C-reactive protein (Hs-CRP) levels in MS.MethodsThirty-five ambulatory patients with relapsing-remitting MS (RRMS) (22 females and 13 males) and 34 healthy controls (21 females and 13 males) with similar demographic variables were included. Blood cell counts, cholesterol levels, vitamin D and B12, Hs-CRP levels, body mass index (BMI), history of smoking, and CIMT of both groups, Expanded Disability Status Scale (EDSS) scores, and disease duration of patients were recorded. Patients with a history of other vascular diseases such as hypertension, diabetes mellitus, peripheral artery disease, and acute relapses were excluded.ResultsSixty-nine participants were included. The mean age of the study population was 35.8 ± 7.1 years. Right CIMT was significantly greater in the patient population (P < 0.001). Spearman's correlation coefficient between age and right CIMT was r = 0.41, P = 0.01. When we compared the Hs-CRP with a cut-off value of ≤ 3, the right, left, and mean CIMT levels were not statistically significant (P = 0.17; P = 0.22; P = 0.15). The mean serum vitamin D levels were higher in the patient group and this was statistically significant (P < 0.001). The statistically significant factors identified with univariate analysis with P < 0.2 were further entered into multivariate modelling.ConclusionCIMT seems to be affected in patients with MS by means of the disease itself and age. Thus, CIMT might reflect the predisposition to subclinical atherosclerosis more than Hs-CRP. Further investigation in a large MS population is still needed.     

Increased oxidative stress in children exposed to passive smoking

BACKGROUND: Atherogenic process is accelerated with cigarette smoke that contains many oxidants and prooxidants, capable of producing free radical and enhancing the oxidative stress. We investigated oxidative and antioxidative status of children who had been exposed to passive smoking and compared with those of not exposed group. METHODS: One hundred forty-three school children aged 9-13 years, 61 of whom had never been exposed to passive smoking, and 82 of whom had been exposed to passive smoking at least 10 cigarette per day for at least last 1 year in their house, were enrolled in this study. Total antioxidative response (TAR) was measured to determine antioxidative status of plasma, and total peroxide concentration was measured to determine oxidative status of plasma. The ratio of TAR to total peroxide was accepted as an indicator of oxidative stress. RESULTS: TAR of plasma was significantly lower in children exposed to passive smoking than in those of not exposed group (p=0.018). Mean (S.D.) values were 1.49 (0.07) and 1.52 (0.08) mmol Trolox Equiv./l, respectively. In contrary, the mean (S.D.) total peroxide level of plasma was significantly higher in children exposed to passive smoking [13.06 (2.34) micromol H2O2/l] than in not exposed group [12.24 (1.74) micromol H2O2/l] (p=0.015). The mean (S.D.) oxidative stress index (OSI) value was significantly higher in the children exposed to passive smoking [0.87 (0.15)] than in not exposed group [0.80 (0.10)] (p=0.001). CONCLUSION: Children who are exposed to passive smoking are exposed to oxidative stress, which has been implicated in the etiopathogenesis of over 100 disorders including atherosclerosis.
