The influence of gender on the relationship between dental anxiety and oral health‐related emotional well‐being

International Journal of Paediatric Dentistry 2013; 23: 180–187 Background and aim. Children’s dental fear and/or anxiety (DFA) has been associated with declines in oral health and quality of life. The influence of gender on the relationship between DFA and oral health‐related well‐being in children is analysed. Design. The decayed, missing and filled permanent teeth (DMFT) index was obtained from 161 school‐aged children (7–14 years old). Data from children’s self‐assessed oral health, oral health‐related emotional well‐being and dental anxiety were collected using questionnaires. Results. Low scores of emotional well‐being were associated with negative self‐assessment of oral health and high levels of dental anxiety. Females reported decreased oral health‐related emotional well‐being compared with males. The analysis of possible moderating effects confirmed that gender influenced the relationship between oral health and DFA. The DMFT index was not associated with self‐assessed oral health status, emotional well‐being or DFA. Conclusion. For girls, high levels of DFA were associated with low levels of oral health‐related emotional well‐being. In contrast, dental fear and/or anxiety did not influence oral health‐related emotional well‐being in boys.     

Incidence of Atrial Fibrillation in Patients with Different Mode of Pacing. Long-term Follow-up

We evaluated the incidence of atrial fibrillation in 189 patients (92males, 97females, mean age 75 ± 12yrs, range 41–100yrs) with pacemaker, during a mean follow-up of 5.5yrs (range 1–24yrs). The indications for implant were: complete AV block (115pts), second degree Möbilz 2 AV block (51pts). bifascicular block (5pts). sick sinus syndrome (14pts), symptomatic bradycardia (4pts). The mode of stimulation considered were VVI (105pt), VVI rate responsive (21pts), single lead VDD (43pts), DDD (20pts). The occurrence of retrograde VA conduction in patients with VVI or VVI rate responsive pacing was also evaluated. Atrial fibrillation occurred in 40 pts (21%). The highest incidence was evidenced in patients with sick sinus syndrome (9pts, 64%), and in patients with VVI stimulation (28pts, 27%). On the contrary, the lowest incidence was found in single lead VDD stimulation (4pts, 9%). The patients with dual chamber pacing showed a relatively high incidence of the arrhythmia (5pts, 25%). Atrial fibrillation occurred in 9 out of 32 patients with retrograde VA conduction, and in 22 out of 94 patients without retrograde conduction (28% versus 23%, p=NS). In conclusion, it is confirmed that patients with sick sinus syndrome are at high risk for atrial fibrillation. Single lead VDD stimulation seems to be the better mode of pacing in preventing atrial fibrillation, while dual chamber pacing showed minor efficacy. The presence of retrograde VA conduction could not predict the occurrence of the arrhythmia.     

Different Trends of Changes in Heart Rate Variability in Patients with Anterior and Inferior Acute Myocardial Infarction

Modifications in heart rate variability (HRV) parameters occur after acute myocardial infarction. The aim of this study was to evaluate the trend of HRV change during the acute phase and the first month after myocardial infarction, and establish whether they were affected by the anterior or inferior location of the infarction. The time-domain HRV measures of 59 patients with a first uncomplicated acute myocardial infarction were computed from 24-hour ECG recordings made on days 1, 2, 10, and 28 after hospital admission. At day 1, the mean RR cycle length (NN), the standard deviation of the NN intervals (SDNN), and the root mean square successive difference of NN intervals (RMSSD) were lower in the patients with anterior myocardial infarction. Although the parameters were similar in all of the patients at day 28, their behavior over time was different (P = 0.01): the SDNN in the patients with inferior myocardial infarction had decreased to the values found in anterior myocardial infarction patients by day 2 but, at day 10, both NN and SDNN tended to recover in both groups; RMSSD had diminished in both groups by day 2, but at day 10, had increased in the patients with anterior, but not in those with inferior myocardial infarction. These findings suggest that (1) in the very early phase of myocardial infarction, HRV is different in the two locations, (2) during the first hours of myocardial infarction patients with inferior location showed a greater vagal activity than patients with anterior location that became lower at day 10, and (3) the recovery of HRV is an early phenomenon in both groups, being already evident by the second week after myocardial infarction.     

Impact of Systematic Isolation of Superior Vena Cava in Addition to Pulmonary Vein Antrum Isolation on the Outcome of Paroxysmal, Persistent, and Permanent Atrial Fibrillation Ablation: Results from a Randomized Study

Impact of the Systematic Isolation of the Superior Vena Cava.   Background: Pulmonary veins (PVs) have been shown to represent the most frequent sites of ectopic beats initiating paroxysmal atrial fibrillation (AF). However, additional non-PV triggers, arising from different areas, have been reported as well. One of the most common non-PV sites described is the superior vena cava.
Aims: The purpose of the study was to investigate the impact resulting from the systematic isolation of the superior vena cava (SVCI) in addition to pulmonary vein antrum isolation (PVAI) on the outcome of paroxysmal, persistent, and permanent AF ablation.
Methods: A total of 320 consecutive patients who had been referred to our center in order to undergo a first attempt of AF ablation were randomized into 2 groups. Group I (160 patients) underwent PVAI only; Group II (160 patients) underwent PVAI and SVCI.
Results: AF was paroxysmal in 134 (46%), persistent in 75 (23%), and permanent in 111 (31%) of said patients. SVCI was performed on 134 of the 160 patients (84%) in Group II. SVC isolation was not performed on the remaining 26 patients either because of phrenic nerve capture or the lack of SVC potentials. Comparison of the outcome data between the 2 groups, after a follow-up of 12 months, revealed a significant difference in total procedural success solely with patients manifesting paroxysmal atrial fibrillation (56/73 [77%] Group I vs. 55/61 [90%] Group II; P = 0.04; OR 2.78).
Conclusions: In our study, the strategy of the empiric SVCI in addition to PVAI has improved the outcome of AF ablation solely in patients manifesting paroxysmal AF. (J Cardiovasc Electrophysiol, Vol. 21, pp. 1–5, January 2010)     

Psoriasis vs allergic contact dermatitis in palms and soles: a quantitative histologic and immunohistochemical study

Cesinaro AM, Nannini N, Migaldi M, Pepe P, Maiorana A. Psoriasis vs allergic contact dermatitis in palms and soles: a quantitative histologic and immunohistochemical study. APMIS 2009; 117: 629–34. A systematic histologic and immunohistochemical study of cases of psoriasis (PSO) and allergic contact dermatitis (ACD) in palmo‐plantar skin was performed to find differences between these two diseases that usually show overlapping features in these specific sites. Skin biopsies from 42 (22 female, 20 male) patients were evaluated for several histopathologic parameters and immunohistochemistry was applied to quantify keratinocytic proliferation, the number of dendritic cells (DCs) and the phenotype of the mononuclear cell infiltrate. Regular epidermal hyperplasia and marked parakeratosis were found to be more frequent in PSO than in ACD cases, but only the first parameter reached the level of significance (p = 0.03). The number of S100 protein‐positive DCs was significantly higher in ACD (p = 0.006), whereas keratinocytic proliferation, studied with Mib‐1, was found to be higher in PSO than in ACD, but the difference was not statistically significant. No significant difference was detected in the number of CD4⁺, CD8⁺ and bcl2⁺ lymphocytes in PSO and ACD cases. In the palms and soles, the finding of irregular epidermal hyperplasia and the detection of a higher number of S100 protein‐positive DCs favor the diagnosis of ACD over PSO. The differential diagnosis between PSO and ACD can be practically approached using a histopathologic parameter and a commercially available antibody.     

Ten-year survival in 290 patients with endometrial cancer: prognostic factors and therapeutic approach

Summary. Between 1970 and 1976, 290 patients with endometrial cancer were treated at the 1st Obstetrics and Gynecology Clinic of the University of Milan. The median age was 62 years. Surgery was completed in 262 (90.3%) patients. Abdominal hysterectomy was used in 158 (70.9%) stage I and 40 (71.4%) stage II/III patients; vaginal hysterectomy in 55 (24.7%) stage I and nine (16.1%) stage II/III patients. Resection of the upper vagina was performed in 168 patients. Postoperative external beam radiotherapy was used in stage II/III patients and in 44 (19.7%) stage I high-risk patients. Ten-year survival, determined by the life-table method, was 84.8% in stage I (223 patients), 53.4% in stage II (37 patients), 64.4% in stage III (19 patients), and 9.1% in stage IV (11 patients). Factors associated with poorer prognosis were: late age at diagnosis (P<0.001); deep myometrial invasion (P<0.001); poorly differentiated histological grade ( P =0.11); lack of resection of the upper vagina ( P = 0.13). The role and importance of surgery is discussed, with special emphasis on the selective use of the vaginal route in aged, obese and medically high-risk patients.     

Characterization of a Precocious New Lesion Distal to a Stent Site by Atherectomy

A 58-year-old woman presented with a new rapidly progressive lesion distal to a stent. This lesion was treated with atherectomy through the stem in order to characterize it pathologically. The aggressive proliferative response discovered suggested that this unusually distal lesion was produced by the trauma of her previous angioplasty .
