New insight into mid-Byzantine burial practices: bioarchaeological implications from the North Cemetery infant remains of the Lower City Church of Amorium (Afyonkarahisar, Turkey) (10th-11th centuries AD).

Amorium is a Byzantine city located in the province of Afyonkarahisar, Turkey. Excavations in the 2007, 2008 and 2009 seasons yielded many tombs containing non-adults, mostly infant burials, located to the north of the Lower City Church while the south of the Church was reserved for family and adult tombs. Among the excavated trenches A20 is the largest area and located immediately to the east of the baptistery, other trenches in the Lower City Church (A17, A19, A22, A35, A36, and A38) are located further away from the baptistery and consist of smaller rooms. Skeletal remains of 280 individuals from these trenches dating to 10th to 11th centuries AD were analysed in order to find out if there are any indications for differences in their social status, preferential choices for the burial places, or age-related distribution of the burials of the non-adults in the North Cemetery. This study, together with the baptism traditions and social hierarchy of the Mid-Byzantine era, tentatively suggests that the A20 area might have been reserved for children of families of higher rank in society as it was the closest area to the baptistery (presumably some of the infants had not lived long enough to be baptised), whereas infants and some older children of lower rank in the society were buried in outlying areas. Hence, this study attempts to offer a new insight into burial practices in mid-Byzantine Amorium.

Characteristics of cardiac device infections in the Isala Hospital; a large volume tertiary care cardiology centre.

AIMS: To determine the frequency, characteristics and risk factors of cardiac device infections in the Isala Hospital. METHODS: We retrospectively studied all patients who underwent cardiac device procedures performed in the cardiac catheterisation lab and the operating room from 2010 to 2012. All patients who developed a cardiac device infection were reviewed for its characteristics. RESULTS: 31/2026 patients developed a cardiac device infection (1.5 %). One (3.2 %) patient died within 30 days of hospitalisation. Device infection rates for procedures in the catheterisation lab and operating room were similar (p = 0.60). Positive cultures were present in 27/31 (87 %) cases. These consisted predominantly of micro-organisms that are part of the skin flora (84 %). The mean time between device procedure and infection was 14 ± 21 months (range 0-79). Cardiac device infection was significantly associated with device revision, (65 % were revisions in patients with device infection vs. 30 % revisions in patients without device infection, p = 0.011) and placement of a left ventricular lead in pacemaker implantations (59 % of patients with vs. 51 % of patients without device infection, p < 0.001). CONCLUSION: The frequency of cardiac device infection was 1.5 % with a mortality of 3.2 % within 30 days, which is lower compared with other registries. Cardiac device infections were associated with device revisions and placement of left ventricular leads in pacemaker implantations.

Prognostic significance of incident atrial fibrillation following STEMI depends on the timing of atrial fibrillation.

Atrial fibrillation (AF) is associated with short-term mortality after ST-elevation myocardial infarction (STEMI), but there is limited data on the temporal association between AF and mortality after STEMI. A total of 830 patients were included (age: 62 ± 12 years, 76 % male). Patients with new-onset AF < 30 days after STEMI were divided among three subgroups: AF on the day of admission, AF 24-72 h and AF > 72 h after admission. Thirty-day mortality was assessed by telephone and via the municipal population registry. Twenty patients died < 30 days after admission. In 41 patients, AF was detected on the day of admission, in 14 patients 24-72 h after admission and in 18 patients > 72 h after admission. Mortality was higher in patients with AF on the day of admission (7.3 vs 2.2 %, p = 0.036) and 24-72 h after admission (14.3 vs 1.4 %, p < 0.001), but not in patients with AF > 72 h after admission (0 vs 1.1 %, p > 0.999). Age (odds ratio (OR) 1.123, p < 0.001), Killip class (adjusted OR 8.341, p < 0.001), AF on the day of admission (OR 3.585, p = 0.049) and 24-72 h after admission (OR 11.515, p = 0.003) were, amongst other variables, associated with an increased 30-day mortality. In conclusion, only new-onset incident AF during the first 72 h after admission was associated with 30-day mortality in STEMI patients.

A case of textile dermatitis due to disperse blue on the surgical wound.

Disperse blue (DB) 106 and DB 124 are the most frequent fabric dye allergens inducing textile dermatitis, but contact allergy to them may easily undiagnosed because the clinical picture usually needs high index of suspicion. We present the case of a 35-year-old woman who was referred for a recurred lesion over the incision scar of right total hip replacement surgery, which did not respond to treatment with povidone-iodine, mupirocin, and rifampicin. Patch testing, conducted with a European standard series and therapeutics that were used in the treatment of the lesion, revealed a positive reaction to dispersion mix blue 106/124. The patient was questioned in detail and reported that she has been wearing dark-colored synthetic panties for long years. The correlation was done between the positive antigen in the patch test and the clinical findings. The patient was treated with a corticosteroid cream for 2 weeks. She did not wear any dark-colored synthetic panties afterward and no flare-up was seen in the follow-up period. In this report, we emphasize the importance of detailed questioning of patients and that contact dermatitis should be considered potential cause of dermatitis at skin sites where the barrier function is compromised.

L-thyroxin treatment in infants with hyperthyrotropinaemia: 4-year experience.

Hyperthyrotropinaemia, in which normal levels of T4 occur in association with raised thyroid stimulating hormone (TSH), is usually picked up on neonatal screening. High TSH level can continue for a long time in some of the cases. There is no consensus concerning the follow-up or treatment plan for hyperthyrotropinaemia. In this study, results of a 4-year follow-up of 36 cases who had been medically treated are discussed. Low-dose (5 microg/kg/day) L-thyroxin treatment was carried out in 36 cases that had 5 mU/l or higher TSH and showed exaggerated response to TRH test. Dose was decreased to 2-3 microg/kg/day in 24 of these patients during 6 months follow-up. The drug was stopped in three cases because of the development of biochemical hyperthyroidism. Denver developmental assessment test was applied to all cases at the end of the third year. All patients showed a normal development in relation to their age. According to our results, cases with hyperthyrotropinaemia need to be followed regularly for a long time and a need for low-dose L-thyroxin treatment may exist at ages varying from patient to patient.

Colour stability of porcelain repair materials with accelerated ageing.

The purpose of this study was to measure and compare the colour stability of three porcelain repair materials (Charizma, Clearfil and Silux Plus) with an all-ceramic material following accelerated ageing. Three composites and one ceramic control were subjected to accelerated ageing for a period of 300 h. Initial specimen colour parameters were determined in the Commission International de I'Eclairage Lab (CIELAB) colour order system with a colorimeter. Colour changes were calculated before (DeltaE) and after 300 h of accelerated ageing (DeltaE*). Colour difference data were subjected to one-way analysis of variance (anova) followed by Duncan's test to examine the interaction between material and time interval of ageing. There were no significant difference between DeltaL values of Porcelain-Charizma and Porcelain-Silux Plus. All mean DeltaL* values were negative after 300 h ageing. Porcelain-Silux Plus demonstrated the highest DeltaL* of the investigated groups. There were significant differences between baseline 300-h aged specimens with respect to Deltaa*, Deltaa for either of the investigated materials. For Silux Plus, Deltaa and Deltaa* values were significantly higher than the others. Significant differences were observed between baseline and 300-h values for Deltab and Deltab*. Deltab and Deltab* values were significantly higher for Silux Plus. There were significant differences between baseline and 300-h values of colour difference, DeltaE, DeltaE*. Highest DeltaE* value was obtained using the microfilled composite, Silux Plus. Lowest value of DeltaE was recorded with the hybrid composite, Charizma.

Does smoking change the efficacy of combination therapy with vitamin E and colchicines in patients with early-stage Peyronie's disease?

This study was conducted to find out if smoking has an effect on the results of combination therapy with vitamin E and colchicines in patients with early-stage Peyronie's disease (PD). A total of 58 potent patients suffering from early-stage PD were included in the study (mean age 47.3 years, range 25-73 y). The time from onset of the disease was <6 months and no patient had ED. The patients with severe fibrotic or calcified plaques were not included in the study. Of the patients, 36 were smokers (Group 1) and 22 were non-smokers (Group 2). All the patients received vitamin E (800 IU daily) and colchicines (1 mg daily) for 6 months. Follow-up ranged from 5 to 13 months (mean 10.3 m). The combination therapy was effective and well tolerated in both groups. There were no significant differences between the two groups according to age, disease duration, related disease (diabetes, hypertension, hypercholesterolemia, and hypertriglyceridemia), plaque sizes, and plaque numbers. The resolution in pain and increase in penile curvature and plaque size were similar rates in both groups (p > 0.05), while decrease in penile curvature and plaque size were higher in Group 2 (p < 0.05). No patient discounted the therapy due to side effects. The oral combination therapy with vitamin E and colchicines appears to be an effective procedure in patients with early-stage PD and smoking may have worsening effects on the treatment results.

Is dorsale penile vein ligation (dpvl) still a treatment option in veno-occlusive dysfunction?

PURPOSE: To determine the long-term results of the DPVL for the treatment of venous impotence. PATIENTS AND METHODS: The long term results of DPVL in 134 patients were interviewed. The mean age was 39.2 (range 21-72). Power color doppler imaging, pharmacocavernography/dynamic cavernosometry were performed. Postoperatively, all the patients were controlled in the 6th month, first year and, if possible, once a year. The mean follow-up was 54.8 (14-76) months. Postoperative outcomes were classified into three groups: complete spontaneous erection (CR), response to pharmacotherapy (PR) or no satisfactory improvement (NR). RESULTS: The short-term success in the 6th month according to above mentioned was 38.8%, 18.6% and 42.5%; and in the first year was 19.4%, 14.9% and 65.6% respectively. The result in 35 patients whose follow-up was at least 5 years (mean 67 months) was 11.4%, 14.3% and 74.3% respectively. Positive prognostic factors were preoperative age <40, duration of erectile dysfunction <2 years, non-smoker patients, non neurogenic disease and distal disease. With all these parameters present, long-term success (CR, PR) rose from 33.6% to 55.9% (P < 0.001). CONCLUSIONS: Long-term success for unselected patients undergoing DPVL is disappointing; however, careful patient selection significantly improves long-term results.

Corrosion susceptibility of titanium covered by dental cements.

Titanium has become a material of great interest in prosthodontics in recent years because of its excellent biocompatibility, corrosion resistance and desirable physical and mechanical properties. In this study, we determined the influence of dental cements on the passivation of titanium. We developed experimental electrodes that associate titanium and dental cements. Polarization resistance of titanium electrodes has been determined for uncovered metal and electrodes covered with five different dental cements. Coverage with zinc eugenate led to more resistance to corrosion, but fluorinated composite such as glass-ionomer and zinc phosphate coverage increased the corrosion susceptibility.

Risk factors for penile prosthetic infection.

OBJECTIVES: To determine the risk factors for penile prosthesis infection. METHODS: The records of 135 penile prosthesis implantation in 127 patients were reviewed. Of the 135 prothesis, 115 were malleable, 12 were self-contained and 8 were inflatable. Of these procedures, 111 were primary, 9 were primary with reconstructions and 15 were secondary. Mean follow-up was 47 months (minimum 6 months). All of the reconstructions were penile plications or plaque excisions for Peyronie's disease. RESULTS: The ratio of penile prosthesis infection was 8.89%. Secondary implantation, paraplegia, non-controlled diabetes mellitus (p < 0.001) and surgeon's inexperience (p < 0.05) were detected as the risk factors for penile prosthesis infection. But age, smoking, alcohol consumption, obesity, atherosclerosis, presence of diabetes mellitus (DM), history of penile surgery, simple penile reconstruction, type of the erectile dysfunction (ED), type of the penile prostheses and incision and were not found as the risk factors (p > 0.05). CONCLUSIONS: Paraplegie, non-controlled diabetes mellitus, secondary implantation and surgeon's inexperience appear to be the risk factors for penile prosthesis infection. In secondary implantation, longer operation time is detected as a factor increasing the risk of penile prosthesis infection. For these patients, careful preoperative preparation, more attention to perioperative antisepsis and postoperative follow-up are required. Since it has been determined that surgical experiences decrease the complication rate, these patients should be operated by experienced surgeons.

Is visualising ureter before pyeloplasty necessary in adult patients?

In this study, we aimed to detect whether or not visualising ureter and ureteropelvic junction (UPJ) preoperatively is necessary in adult patients who have primer UPJ obstruction. Between January 1995 to June 1999, 46 renal units in 45 patients with primer UPJ obstruction were evaluated. The patients were separated into 2 groups. In group 1, intravenous pyelography (IVP) and renal scintigraphy were performed to 17 renal units preoperatively. In group 2, in addition to these methods, either retrograde pyelography (RGP) or antegrade pyelography (AGP) were performed to 29 renal units. Renal/bladder sonogram was used in patients with poor renal function in IVP or in renal scintigraphy. All the operations were performed through a flank incision. In group 2, additional information was gained for 8 (27.5%) of the renal units preoperatively. No additional information for this group found intraoperatively. In group 1, we found additional information in 4 (23.53%) of the units intraoperatively. All the pathologies in both groups were corrected intraoperatively. Double-J (D-J) stent was used in 6 (35.29%) of the units in group 1 and 8 (27.58%) of the units in group 2 intraoperatively (p > 0.05). In group 2, 4 (13.79%) preoperative complications were seen due to RGP and they were treated either medically or conservatively. In the early postoperative period, a complication observed in 1 (5.88%) of the patients in group 1 and 1 of the patients in group 2 (3.44%) (p > 0.05). The first patient was treated with inserting D-J and the latter one was treated conservatively. In the 3rd postoperative month, success rate was found to be 94.11% in group 1 and 96.55% in group 2 (p > 0.05). Additional pathologies in adult patients with primer UPJ obstruction can be corrected intraoperatively through a flank incision. Therefore, imaging of ureter and UPJ may not be necessary in these patients.

The relations between alveolar ridge and the teeth located in neutral zone.

The neutral zone is defined as the area where the forces of the tongue pressing outward are neutralized by the forces of the cheeks and lips pressing inward. In this study records of neutral zones of 30 edentulous patients were used to establish the relation between teeth arrangement according to neutral zone principles and teeth arrangement according to crest of ridge. These 30 patients were classified according to their ages, edentulous periods and denture experience. The results have shown that the lower molars were positioned a little bit closer to lingual with respect to crest of ridge; premolars were positioned either close to crest of ridge or they were coincided on it. In the anterior zone, the teeth were in accordance with known principles of positioned of anatomic landmarks.

Extracorporeal shock wave lithotripsy in children.

An experience with 103 children treated with extracorporeal shock wave lithotripsy (ESWL) is reviewed in this report. The success rate was 63%. The stone volume was of major importance for the result. There was a continuous decrease in success rate with increasing stone size. It was also shown that stone-free rates decreased with an increasing number of stones. Short-term complications were minor and hospitalization times were short. It is concluded that ESWL is a first-choice treatment in children with urinary calculi smaller than 200 mm2 in size.

A comparison of stress and strain distribution characteristics of two different rigid implant designs for distal-extension fixed prostheses.

Stress and strain patterns around two rigid implant designs used as an abutment were compared and the displacement of natural teeth was investigated. The finite-element method was utilized to determine the stress and strain distributions. The results were evaluated in terms of the maximal tensile and compressive stress and strain in the bone around the abutment tooth and implants. The results indicated that the ITI 1 (hollow screw) implant led to high stress concentrations particularly in the apical region. The stress-transferring characteristics of ITI 2 (solid screw) implant were found to be more suitable than were those of ITI 1.
