ABSTRACT

OBJECTIVES: Comparing PES/WES scores, modified success rate, survival, success, buccal bone thickness and patient-reported outcomes of immediate dental implants placed in fresh alveolar sockets using a flap or a minimal split-thickness envelope flap (MSTEF).

MATERIALS AND METHODS: Implants following random assignment into a flap or MSTEF group were placed immediately in anterior and premolar areas. Guided bone regeneration and autogenous connective tissue graft were used in all cases. A temporary prosthesis was provided followed by the final prosthesis at 16-18 weeks. Success and survival rates together with radiographic buccal bone thickness and patient satisfaction were evaluated at 12 months post-loading. The aesthetic outcome was evaluated through the Pink (PES) and White (WES) Aesthetic Score by 8 blind clinicians of different training background and incorporated in modified success criteria.

RESULTS: 28 implants were placed on 28 patients. No statistically significant differences were noted in PES (10.54 control vs. 10.80 test), WES scores (6.97 control vs. 6.95 test) or success criteria including aesthetic parameters (modified success criteria) for the different specialty groups (Range 69%-92%). In addition, no statistically significant differences were noted in survival (100%), success (100%), buccal wall thickness between control (0.72 +/-0.22) and test group (0.92+/-0.31) and patients’ reported outcomes.

CONCLUSIONS: Immediate dental implant treatment with flap/ MSTEF provided similar mean PES/WES scores, modified success rate, survival, mean buccal bone levels and patients’ satisfaction. However, aesthetic failures were common in both groups.

ABSTRACT

INTRODUCTION: No clinical studies to date have compared the airway luminal area between supine and standing positions. Our aim was therefore to compare the airway luminal area between these two positions on computed tomography (CT) and to determine its correlation with forced expiratory volume in 1s (FEV1).

MATERIALS AND METHODS: Thirty-two asymptomatic volunteers underwent both conventional (supine position) and upright (standing position) CT during deep inspiration breath-holding. Pulmonary function tests were conducted on the same day. We measured the airway luminal area on CT in each position. Paired t-tests and Pearson’s correlation coefficients were used for statistical analysis.

RESULTS: The average luminal areas of the trachea, right and left main bronchi, and average third-generation airway were greater in the standing than the supine position by 3.4%, 6.1%, 5.5%, and 5.2%, respectively. The correlation coefficients between airway luminal areas and FEV1 tended to be higher in the standing than the supine position; this correlation was highest for the average third-generation airway (r=0.70, P <0.0001).

CONCLUSION: The airway luminal areas of the trachea, bilateral main bronchi, and average third-generation airway were greater in the standing than the supine position. The average third-generation airway area in the standing position had the highest correlation with FEV1. This article is protected by copyright. All rights reserved.

ABSTRACT

BACKGROUND: Despite improvements in many health indicators, providing access to affordable healthcare remains a considerable challenge in Bangladesh. Financing incidence analysis will enable an evaluation of how well the healthcare system performs to achieve equity in health financing. The objective of this study is to assess the burden of out-of-pocket (OOP) cost on different socio-economic groups by assessing the health financing incidence because OOP cost dominates household expenditure on health in Bangladesh.

METHODS: The study was conducted using latest Household Income and Expenditure Survey (HIES) 2016. We focused mainly on four specific indicators: level of monthly household OOP cost on in-patient care, urban-rural differences in OOP cost, socio-economic status differences in different payment mechanisms and the Kakwani index. Descriptive statistics were employed to analyse and summarise the selected variables based on the SES and location of residence (e.g., rural and urban).

RESULTS: The study showed the overall OOP healthcare expenditure was 7.7% of the household monthly income while the poorer income group suffered more and spent up to 35% of their household income on healthcare. The Kakwani index indicated that the poorest quintile spends a greater share of their income on healthcare services than the richest quintile.

CONCLUSIONS: This study observed that OOP cost in Bangladesh is regressive, that is, poorer members of society contribute a greater share of their income. Therefore, policymakers should initiate health reforms for developing and implementing risk-pooling financing mechanisms such as social health insurance to achieve the Universal Health Coverage in Bangladesh.

ABSTRACT

Migraine is considered an underdiagnosed disease in general population. Different studies show a higher prevalence in neurologists. However, there are few studies about its prevalence in doctors of other specialties, where it could also be superior than in general population. Our aim was to define migraine lifetime prevalence among doctors according to three parameters (previous diagnosis, self-diagnosis and positivity of a screening test). Single-center, descriptive, cross-sectional study based on online surveys with collection of sociodemographic and clinical variables, addressed to doctors of a tertiary hospital. Participants who reported 5 or more headaches throughout their lives were considered “headache sufferers” and were divided in different groups according to their position (specialists or trainees) and their specialty (medical, medical-surgical and surgical or specialties with no direct contact with the patient). The Spanish validated version of the Migraine Screen Questionnaire (MS-Q) was used as screening test. There were 217 participants (response rate of 29%), 72% were women and 56% trainees, mean age 34 years (SD10). 77% were “headache sufferers” Among all participants, migraine lifetime prevalence according to diagnosis by another physician was 15.2%, self-diagnosis 38.2% and positivity of the MS-Q 20.3%; those categories were not mutually exclusive Greater but not statistically significant coexistence of self-diagnosis and positive MS-Q was seen in specialists compared to trainees and in medical specialties. Migraine prevalence among doctors in a tertiary care hospital was higher than in general population, according to all three parameters analyzed. Self-diagnosis was the highest which could reflect an overdiagnosis; further studies are needed to determine this possibility.

ABSTRACT

This theoretical analysis considers a biomechanical model in which the Carreau fluid model characterizes the viscoelastic nature of growing human embryo and secreted fluid. This model incorporates transport mechanisms that involve the swaying motions of ciliary cells, peristaltic contractions of smooth muscle cells and pressure gradient at the ampullar region entrance. Series form solutions of the resulting partial differential equations are obtained using the regular perturbation method. A theoretical estimate of effects of the condition of pressure gradient, geometric parameters and fluid model parameters on the flow variables that have relevance to the problem of growing embryo transport in the human fallopian tube is presented through the discussion of graphs. Furthermore, an analogy between the linearly viscous fluid, and the shear thinning and shear thickening characteristics of the Carreau fluid model is also presented. The pertinence of the obtained results with growing embryo transport in the human fallopian tube revealed that when shear thickening characteristics of the Carreau fluid model are considered then complete mitotic divisions take place properly with an estimated appropriate residue time about 3-4 days. Smaller size trapped boluses of the secreted fluid make the smooth forwarding of the growing embryo in the human fallopian tube when shear thinning characteristics of the Carreau fluid model are taken into account. Key modulators: progesterone ([Formula: see text] and estradiol ([Formula: see text]), prostaglandin [Formula: see text] ([Formula: see text]) and prostaglandin [Formula: see text] ([Formula: see text]) constraint the growing embryo transport.

ABSTRACT

BACKGROUND: Hepatitis C is a viral infection caused by the hepatitis C virus (HCV) with people who inject drugs as the main group at risk worldwide.

AIM: This study investigated the differences in uptake for HCV screening and treatment between persons in opioid substitution therapy (OST) and the other members of the Christian Health Insurance Fund in Belgium.

METHODS: Invoice data were retrospectively collected from the Christian Health Insurance Fund, representing 42% of the healthcare users. Information on demographics, screening, diagnostic tests, treatment and disease progression was obtained from 2008 till 2013. All people in this study were aged 20-65 year. Persons in the OST group were identified as having at least one prescription reimbursed for methadone. This group was compared to the other members of the Insurance Fund not on OST (NOST).

RESULTS: The Insurance Fund registered 8,409 unique OST and 3,525,190 members in the general group. HCV RNA screening rate was higher in the OST group after correction for age and gender (4.3% vs. 0.2%). Ribavirin reimbursement, did not differ between the OST and NOST group screened for HCV RNA (16.9% vs. 14.4%), though the probability of having ribavirin reimbursed was smaller for females than for males. Procedures concerning disease progression were reimbursed less frequently in the HCV RNA screened OST group compared to the NOST group (0.3% vs. 1.2%).

CONCLUSION: People on OST were screened more often for HCV RNA. However, the general uptake for HCV screening and treatment in both populations remained suboptimal.

ABSTRACT

BACKGROUND AND STUDY AIMS: Transanal irrigation (TAI) is used in children to treat constipation and incontinence. Belgium has 2 systems available: Colotip® (cheaper, however not designed for TAI) or Peristeen®.

PATIENTS AND METHODS: This patient-control switch study is the first to compare 2 TAI systems. Children regularly using Colotip® for TAI were asked to participate, after consent, a visual analogue scale (VAS) rating the system and a 2-week diary (fecal continence, self-reliance, time spent on the toilet, pain, Bristol stool scale, irrigation volume and frequency of enema) were completed. Non-parametric statistics were used.

RESULTS: Out of 26 children using Colotip®, 18 (69%) children participated and 5 refused (fear n=1, satisfaction Colotip® system n=7). Of these 18 children (interquartile range: 3-18 years, median 12.5 years, 9 girls) 5 patients stopped Peristeen® (pain n=1, fear n=1 and balloon loss n=3) and 2 were lost from follow up. Dropouts and included patients showed no statistical difference. In the 11 remaining patients, pseudo-continence (p 0.015), independence (p 0.01) and VAS score (p 0.007) were significantly better with Peristeen®, no difference was found in time spent on the toilet (p 0.288) and presence of pain (p 0.785).

CONCLUSIONS: In children Peristeen® offered significantly higher pseudo-continence and independency. 30% refused participation because of satisfaction with the Colotip® and 30% spina bifida patients reported rectal balloon loss due to sphincter hypotony. To diminish Peristeen® failure, a test-catheter could be of value. Considering Colotip® satisfaction, both systems should be available. Patient selection for Peristeen® needs further research.

ABSTRACT

BACKGROUND AND STUDY AIM: In principle, additional surgery is performed after endoscopic submucosal dissection for early gastric cancer if the vertical margin is positive, regardless of lesion damage. The recurrence rate of vertical margin-positive lesions due to lesion damage after endoscopic submucosal dissection is unknown, and unnecessary surgeries may be performed. In this study, we investigated whether there was a difference in the recurrence rate between vertical margin-positive lesions due to lesion damage and vertical margin-negative lesions.

PATIENTS AND METHODS: We included 1,294 intramucosal gastric cancer lesions that were resected by endoscopic submucosal dissection between January 2008 and December 2016, without additional surgery. The lesions were divided into the Damage and No damage groups based on vertical margin status. The Damage group had only one non-curative indication: a positive vertical margin due to lesion damage. The No damage group had no non curative indications. We compared the recurrence rate between the Damage and No damage groups.

RESULTS: The recurrence rates of the Damage and No damage groups were 0% (0/23; 95% confidence interval: 0-14.8%) and 0% (0/1,271; 95% confidence interval: 0-0.003%), respectively, with no statistically significant difference.

CONCLUSIONS: In intramucosal gastric cancer, the recurrence rate of vertical margin-positive lesions due to lesion damage was 0%, which did not differ from that of vertical margin-negative lesions with curative resection. Follow-up, instead of additional surgery, may be an option for patients with non-curative resection when the only non-curative indication is a positive vertical margin due to lesion damage.

ABSTRACT

BACKGROUND/AIM: Currently, the elderly population in the world is rapidly increasing due to technological developments and convenient access to health services. Due to comorbidities in elderly patients, hip fractures are frequently observed after exposure to environmental trauma. To reduce pain during positioning in spinal anesthesia, fascia iliaca compartment block (FICB) can be applied easily and reliably. In our study, we aim to compare the analgesic effects and duration of Fascia iliaca compartment blocks performed Usg guided or Landmark approach methods in relieving spinal anesthesia position pain.

MATERIALS AND METHODS: Our study included 100 patients undergoing operations due to hip fracture and administered spinal anesthesia after FICB. The group USG guided FICB(USG) had the blockage needle advanced to the compartment under the fascia iliaca and 15 mL bupivacaine + 10 mL 2% lidocaine was administered. Sitting position was given for spinal anesthesia 20 minutes later and procedure duration and Numerating Rating Scale(NRS) scores were recorded. In the group Landmark approach FICB(LAND), the spina iliaca anterior superior (SIAS) and pubic tubercle were connected with a line. The same amount of local anesthetic was administered to the external 1/3 portion of this line with the double pop technique. Procedure duration and NRS scores were recorded.

RESULTS: There was no statistically significant difference between two groups in terms of NRS scores (p>0.05). There was a statistical difference duration of FICB administration between two groups(p<0.05).

CONCLUSION: Both USG-guided and landmark approach FICB methods provide adequate and similar analgesia for positioning spinal anesthesia. However, in cases where there is no problem of access to the ultrasound device or time problem, a safer blockage can be made by imaging neurovascular structures with ultrasound.

ABSTRACT

OBJECTIVES: To investigate the effect of short-term spinal cord electrical stimulation (stSCS) on postherpetic neuralgia (PHN) and its effect on sleep quality in patients in Guangxi, China.

MATERIAL AND METHODS: 160 patients with acute PHN patients were divided into a control group and an experimental group according to the random number table method, 80 cases each. The experimental group was implanted with percutaneous epidural electrodes and given short-term spinal cord electrical stimulation treatment, while the control group was treated with nerve block therapy to compare the efficacy and sleep quality of the two groups of patients in different periods. Pain Visual Analogue Scale (VAS) score and Pittsburgh Sleep Quality Index (PSQI) were used to evaluate the analgesic effect and sleep quality, respectively.

RESULTS: The patients in the experimental group had significantly lower visual analog scale (VAS) scores and Pittsburgh Sleep Quality Index (PSQI) scores at 1, 2, 3 d, 1 week, and 1 and 3 months after treatment than those in the control group [after treatment 3 months: (0.86±0.31) points to (2.97±0.55) points, (5.4±1.16) score to (7.46±1.27) score], the difference was statistically significant (both P<0.05), and VAS and PSQI scores of the two groups showed a significant downward trend with the increase of treatment time.

CONCLUSION: The clinical effect of short-term spinal cord electrical stimulation on PHN is good, and it can play a rapid and effective relief effect on pain in patients. At the same time, it will effectively improve patient’s sleep quality, with high safety.
