Efficacy of cement-augmented pedicle screw fixation for osteoporotic mid-thoracic vertebral fractures.

Background: Osteoporotic mid-thoracic vertebral fractures (OmTVF), often result in severe pain, and neurological deficits secondary to cord compression. Cement-augmented pedicle screw (CaPS) fixation with posterior spinal decompression (PSD) offers simultaneous decompression with stabilization of these osteoporotic vertebral fractures. Methods: The study involved 32 patients (2022-2023) with T8-T10 osteoporotic vertebral compression fractures resulting in cord compression. All patients underwent CaPS surgery with PSD. Pain reduction was measured using the visual analog scale (VAS), and outcomes with the Oswestry Disability Index, and the American Spinal Injury Association Grades. The local kyphotic angle was also tracked with computed tomography studies performed 1, 3, and 6 months post-operatively. Results: The average pre-operative VAS score was 8.56 mm; this decreased at 1, 3, and 6 months post-operatively to 2.72 mm, 2.03 mm, and 1.44 mm, respectively. In addition, 31 of 32 patients fully recovered within 6 postoperative months. Conclusion: For 31 of 32 patients with T8-T10 osteoporotic vertebral fractures, CaPS fixation with PSD successfully alleviated pain and resulted in significant post-operative neurological recovery.

Levofloxacin+Tetracycline Quadruple Regimen for Eradication of Helicobacter pylori: A Multicenter Multinational Randomized Controlled Trial.

Background: The ideal combination regimen for Helicobacter pylori (HP) eradication has not yet been determined and the success rate of HP eradication has been extensively reduced worldwide due to increasing antibiotic resistance. So this multinational multi-center randomized controlled trial was designed to evaluate the efficacy of tetracycline +levofloxacin for HP eradication. Methods: During a 6-month period, all of the cases with HP infection in eight referral tertiary centers of three countries were included and randomly allocated to receive either tetracycline + levofloxacin or clarithromycin plus amoxicillin quadruple regimen for two weeks. For all of the participants, pantoprazole was continued for 4 more weeks and after one to two weeks of off-therapy, they underwent urea breath test C13 to prove eradication. Results: Overall 788 patients were included (358 male (45.4%), average age 44.2 years). They were diagnosed as having non-ulcer dyspepsia (516 cases, 65.5%), peptic ulcer disease (PUD) (234 cases, 29.69%), and intestinal metaplasia (38 cases, 4.8%). Racially 63.1% were Caucasian, 14.5% Arab, 15.6% African, and 6.1% Asian. The participants were randomly allocated to groups A and B to receive either tetracycline + levofloxacin or clarithromycin. Among groups A and B in intention to treat (ITT) and per protocol (PP) analysis, 75.2% & 82.1% (285 cases) and 67.5% & 70.1% (276 cases) of participants achieved eradication, respectively (P = 0.0001). The complete compliance rate in groups A and B were 84.4% and 83.6%, respectively. During the study, 33.5% of the participants in group A (127 cases) reported side effects while the complication rate among group B was 27.9% (114 cases, P = 0.041). The most common complaints among groups A and B were nausea and vomiting (12.6% & 9.3%) and abdominal pain (4.48% & 2.68%), respectively. The rate of severe complications that caused discontinuation of medication in groups A and B were 2.1% and 1.46%, respectively (P = 679). In subgroup analysis, the eradication rates of tetracycline+levofloxacin among patients with non-ulcer dyspepsia, PUD, and intestinal metaplasia were 79.4%, 88.1%, and 73.9%, respectively. These figures in group B (clarithromycin base) were 71.3%, 67.6%, and 61.5% respectively (P = 0.0001, 0.0001, and 0.043). Conclusion: Overall, the combination of tetracycline+levofloxacin is more efficient for HP eradication in comparison with clarithromycin+amoxicillin despite more complication rate. In areas with a high rate of resistance to clarithromycin, this therapeutic regimen could be an ideal choice for HP eradication, especially among those who were diagnosed with PUD.

Anterolateral thigh adipofascial flap combined with skin paddle in three-dimension scalp reconstruction: A case report.

INTRODUCTION AND IMPORTANCE: Management of cranial and scalp defects is always challenging. Complication rates following cranioplasty are still high (10-40 %), including bone graft resorption, infection, and T-mesh implant exposure due to thinning of soft tissue (Yeap et al., 2019; Alkhaibary et al., 2020; Cho and Kang, 2017 [1-3]). CASE PRESENTATION: We present a case of a 38-year-old male with autologous bone graft resorption accompanied by thinning of the forehead skin. He underwent cranioplasty with titanium mesh (T-mesh) and scalp reconstruction with an anterolateral thigh (ALT) flap in a single-stage operation. A 2-component ALT flap was used: the skin paddle covered the scalp defect to reduce closure tension, and especially the adipofascial flap lining beneath the forehead skin to increase thickness. Postoperative results were great in terms of coverage function and aesthetics. CLINICAL DISCUSSION: The phenomenon of soft tissue thinning causing titanium mesh exposure is a common complication with a rate of 10-14 % (Yeap et al., 2019; Dong et al., 2020; Maqbool et al., 2018 [1, 4, 5]). Using adipofascial ALT flap as a sub-scalp filler material has many advantages over the latissimus dorsi (LD) flap to increase scalp thickness but still ensure aesthetics. CONCLUSION: The results suggest a new direction in using adipofascial ALT flap as filler material to increase scalp thickness to reduce T-mesh exposure following cranioplasty.

Quantifying antimicrobial access and usage for paediatric diarrhoeal disease in an urban community setting in Asia.

Objectives: Antimicrobial-resistant infections are a major global health issue. Ease of antimicrobial access in developing countries is proposed to be a key driver of the antimicrobial resistance (AMR) epidemic despite a lack of community antimicrobial usage data. Methods: Using a mixed-methods approach (geospatial mapping, simulated clients, healthcare utilization, longitudinal cohort) we assessed antimicrobial access in the community and quantified antimicrobial usage for childhood diarrhoea in an urban Vietnamese setting. Results: The study area had a pharmacy density of 15.7 pharmacies/km2 (a pharmacy for every 1316 people). Using a simulated client method at pharmacies within the area, we found that 8% (3/37) and 22% (8/37) of outlets sold antimicrobials for paediatric watery and mucoid diarrhoea, respectively. However, despite ease of pharmacy access, the majority of caregivers would choose to take their child to a healthcare facility, with 81% (319/396) and 88% (347/396) of responders selecting a specialized hospital as one of their top three preferences when seeking treatment for watery and mucoid diarrhoea, respectively. We calculated that at least 19% (2688/14427) of diarrhoea episodes in those aged 1 to <5 years would receive an antimicrobial annually; however, antimicrobial usage was almost 10 times greater in hospitals than in the community. Conclusions: Our data question the impact of community antimicrobial usage on AMR and highlight the need for better education and guidelines for all professionals with the authority to prescribe antimicrobials.

Effects of glucose and probiotic supplementation in nursing juvenile clam, Meretrix lyrata.

This study was conducted to evaluate the effects of different glucose concentration on the survival and growth rate of juvenile hard clam, Meretrix lyrata. Juvenile clams M lyrata were cultured with algae from a tilapia-greenwater system and different concentrations of glucose (0, 35, and 70microg.l-1). After 70 days of culture, highest survival rate was obtained with 35microg.l-1 glucose supplementation (99.5-100%). However, in highest concentration of glucose, weight gain and shell length of clams reached highest values (p<0.05). Our findings showed that supplementation of probiotics and suitable glucose concentration in the nursery period could increase survival and growth rate of clams.
