Introduction/Objective. Contemporary tendencies suggest that probiotics can significantly reduce the prevalence of caries in children, so it can be considered that they have a positive effect on general and oral health. Lactobacillus rhamnosus GG (LGG) is a probiotic culture of particular importance in preventive dentistry. The aim was to assess the effects of consumption of probiotic strain Lactobacillus rhamnosus GG on the dental plaque accumulation in children with mixed dentition. Methods. Research included 90 children with mixed dentition (5-12 years old). First study group consumed 200 ml of Lactobacillus rhamnosus GG-enriched yogurt (B-Activ LGG, Dukat) daily for a period of 14 days, while the remaining 30 formed the second study group who consumed 200 ml of yogurt (Jogurt 1,5% milk fat, Imlek) with manually added powder from probiotic capsule (Wayaforte LGG capsule, Medis) daily for14 days. The control group consisted of 30 children who had regular diet during examination period. Silness-L?e plaque index and saliva pH (pH-Fix-0-14, Macherey-Nagel) were determined at baseline and also upon intervention completion. Results. An increase in pH values was observed in both study groups. In general sample, there is a significant decrease of mean plaque index values (p ? 0.001). Both study groups had significant decrease of mean plaque index values on the baseline and after 14 days consumption of yogurt. In the control group the number of subjects with decrease plaque index values did not correlate and no association was found. Conclusion. Consistent consumption of LGG culture-enriched yogurt inhibits dental film accumulation and promotes saliva pH increase in children with mixed dentition.

Malnutrition affects virtually all organ systems, and malnourished children are more prone to infections. These children have dysbiosis, but probiotics can restore the disrupted gut microbiome. We investigated the protective effects of Lactobacillus rhamnosus GG in malnourished children in terms of incidence of infection, and anthropometric and metabolic parameters. 50 intervention and 50 control patients, aged 6 months to 5 years, with body weight and height below -2 SD, were randomly and prospectively recruited. The controls received a calorie and protein-appropriate diet for 3 months, while the study group additionally received approximately 109 L. rhamnosus GG for 3 months. Infection episodes and nutritional status were compared between the groups. 38 intervention, 33 control patients completed the study and the two groups were similar at baseline. The study group had fewer upper respiratory tract infections and gastroenteritis episodes at each month and at the end of the study. Children in the study group experienced fewer total upper respiratory infections and urinary tract infections. Hospitalisation was more frequent in the control group during the third month and at the end of the study. Total infection numbers were higher in the control group at each month and at the end of the study (P<0.001 for each). Increments in body mass index (BMI) and BMI Z-scores were more pronounced in the study group (P=0.008 and P=0.02, respectively). Daily prophylactic use of L. rhamnosus GG at 109 bacteria in malnourished children prevents most infections and improves nutritional status when used together with appropriate diet.

Rhinovirus Infection

The aim of this work was to investigate the usability of an experimental rhinovirus model in probiotic trials aiming to assess effectiveness in viral infections, and to provide preliminary data of live and inactivated probiotic Lactobacillus rhamnosus GG for larger-scale trials utilising the model. 59 subjects were randomised to receive 100 ml of fruit juice supplemented with 109 cfu of live or heat-inactivated (by spray-drying) L. rhamnosus GG or control juice daily for six weeks. After three weeks subjects were intranasally inoculated with experimental rhinovirus. Infection rate (at least one positive culture for challenge virus on five days following inoculation or at least four-fold rise in antibody response to challenge virus) was 14/19 in the group receiving live probiotic strain and 18/20 both in the group receiving heat-inactivated probiotic strain and in the control group (P=0.36). The occurrence and severity of cold symptoms on the five days following the inoculation was lowest in the group receiving live probiotic strain (P=0.45). This trial was the first one dedicated to the investigation of the effect of probiotics using the experimental rhinovirus model. The model showed potential for demonstration of efficacy of probiotics in controlled respiratory viral infections. Occurrence and severity of cold symptoms and number of subjects with rhinovirus infection was lowest in the group receiving live L. rhamnosus GG, but differences were not statistically significant. Further large-scale studies are needed to demonstrate the efficacy of L. rhamnosus GG in respiratory infections.

Objective: To analyze safety and efficacy of single-dose ketorolac after primary palatoplasty (PP). Design: Consecutive cohort of patients undergoing PP, comparing to historical controls. Setting: A large academic children’s hospital. Patients, Participants: A consecutive cohort of 111 patients undergoing PP (study n = 47) compared to historical controls (n = 64). Interventions: All patients received intraoperative acetaminophen, dexmedetomidine, and opioids while the study group received an additional single dose of ketorolac (0.5 mg/kg) at the conclusion of PP. Main Outcome Measures: Safety of ketorolac was measured by significant bleeding complications and need for supplementary oxygen. Efficacy was assessed through bleeding, Face Legs Activity Cry Consolability (FLACC) scale, and opioid dose. Results: Length of stay was similar for both groups (control group 38.5 hours [95% CI: 3.6-43.3] versus study group 37.6 hours [95% CI: 31.3-44.0], P = .84). There were no significant differences in all postoperative FLACC scales. The mean dose of opioid rescue medication measured as morphine milligram equivalents did not differ between groups ( P = .56). Significant postoperative hemorrhage was not observed. Conclusions: This is the first prospective study to evaluate the safety and efficacy of single-dose ketorolac after PP. Although lack of standardization between study and historical control groups may have precluded observation of an analgesic benefit, analysis demonstrated a single dose of ketorolac after PP is safe. Further investigations with more patients and different postoperative regimens may clarify the role of ketorolac in improving pain after PP.

Abstract Purpose To quantitatively investigate the role of deep capillary plexus (DCP) in patients affected by type 3 macular neovascularization (MNV), compared to patients with reticular pseudodrusen (RPD) eyes and healthy controls, using optical coherence tomography angiography (OCTA). Methods In this prospective observational study, a total of seventy-eight eyes of 78 patients were included. Group 1 consisted of 40 eyes of 40 patients with stage 1 of type 3 MNV (22 males, 18 females, mean age 73.7, SD ± 6.60) and group 2 included 38 eyes of 38 patients with RPD (17 males, 21 females, mean age 73.2, SD ± 4.55). The control group included 40 eyes of 40 healthy subjects (20 males, 20 females, mean age 71.4, SD ± 6.36 years). We evaluated the retinal vessel density (VD) of superficial capillary plexus (SCP) and deep capillary plexus (DCP) using OCTA. Results Patients with diagnosis of type 3 MNV showed statistically lower values of VD in DCP with respect to controls and to RPD group (p < 0.001), while there were no statistical differences between RPD and control group in macular region. No significant differences in VD of SCP were detected among the three study groups. Conclusion OCTA provides a reproducible, non-invasive detailed quantitative analysis of retinal vascular features and changing in early-stage type 3 MNV patients, which allowed to shed the light on the main role of DCP ischemia in the development of type 3 MNV.

Abstract Objectives The aim of this study was to investigate the role of CD68 (+) histiocytic macrophages (H-M) in the nasal polyp pathogenesis. Materials and Methods The study group consisted of 24 adult patients with nasal polyposis. The control group consisted of 11 adult patients without nasal polyps. A total of 36 nasal polyp samples (10-nasal cavity, 10-maxillary sinus, and 16-ethmoid sinus) from the study group and 11 inferior turbinate samples from the control group were analyzed by immunohistochemical staining, with monoclonal antibodies against CD68 (+) H-M. Results CD68 positivity was significantly higher than the control group in the subepithelial (SE) layer of the ethmoid sinus, and deep layers of nasal cavity, maxillary, and ethmoid sinuses. In SE and deep layers of ethmoid and maxillary sinuses, CD68 positivity was significantly higher than that of the epithelial layer. In the deep layer, histiocytic macrophages tended to gather around eosinophils. Conclusion The high numbers of CD68 (+) histiocytic macrophages mainly located in deep layer of lamina propria may be responsible for the phagocytosis of eosinophils within the polyp tissue. Therefore, it may be concluded that increased macrophages in nasal polyps do not trigger the growth of nasal polyps. Instead, they may serve to reduce the number of eosinophils in already-developed nasal polyps.

The aim of this study was to evaluate the effect of toothpaste containing natural tea tree essential oil (TTO) and ethanolic extract of propolis (EEP), on microflora and selected indicators of oral health in patients using removable acrylic partial dentures. Fifty patients with varying conditions of hygiene were divided into two groups. The study group received the toothpaste with TTO and EEP, while the control group received the same toothpaste but without TTO and EEP. At the first visit, oral hygiene and hygiene of the prostheses were carried out. Control visits took place 7 and 28 days later and compared to baseline. Indexes like API (Approximal Plaque Index), mSBI (modified Sulcus Bleeding Index), OHI-s (simplified Oral Hygiene Index), and DPI (Denture Plaque Index) were assessed in three subsequent stages, and swabs were collected from floor of the mouth area to assess the microbiota. After 7 and 28 days of using the toothpaste with TTO and EEP, a statistically significant decrease of the examined indicator values were observed in the study group as compared to the values upon the initial visit. The number of isolated strains of microorganisms in the study group was decreased or maintained at the same level, whereas in the control group an increase in the number of isolated strains was observed. The observed stabilization of oral microbiota in patients from the study group confirms the beneficial activity of toothpaste containing EEP and TTO compared to the control group.

In Reply.— We appreciate the interest in our report published in Pediatrics (1986;77:212-216). The three letters raise similar questions, and in response we would like to make three points. First, including the two infants in the control group who died with the infants in the study group still resulted in significant differences between the two groups regarding duration of furosemide (Lasix) therapy, hypochloremia, or metabolic alkalosis (P &gt; .001). Second (as noted in our discussion), bronchopulmonary dysplasia is a complex disease process.

Abstract Many serious and fatal infections with urogenital mycoplasmas in immunocompromised patients have been reported. M. genitalium is recognized as a cause of male urethritis and other common genitourinary diseases. The aim of the study was to estimate prevalence of urogenital mycoplasmas which can cause complications in men with common genitourinary diseases. Study included 85 men with genitourinary tract carcinoma (n = 35), urolithiasis (n = 36), and BPH (benign prostatic hyperplasia) (n = 14). The control group consisted of 50 healthy men. FVU (first void urine) samples were examined by PCR for the presence of urogenital mycoplasmas DNA. Occurrence of urogenital mycoplasmas was significantly more common in study group compared with control 24/85 (28.2%) and 7/50 (14%), respectively (p = 0.05). In men with urolithiasis, positive results for mycoplasmas DNA were significantly more frequent than in control: 33.3% vs. 14% (p < 0.05). In patients with urolithiasis DNA of U. urealyticum was most often found, while in the genitourinary carcinoma and BPH groups, U. parvum was more frequent. Incidence of M. fermentans was also significantly higher in the urolithiasis group vs. control (p = 0.03). A higher percentage of positive results for urogenital mycoplasma DNA in study group has been found. Further studies are required to confirm the role of urogenital mycoplasmas in the development of infectious complications among patients with urolithiasis, genitourinary carcinoma, and BPH.

Background: Alopecia areata is an autoimmune disorder causing patchy hair loss on scalp and other parts of the body and leading to poor self-esteem and anxiety in patients. Treatment with topical or systemic drugs like steroids or other immunosuppressants is associated with adverse effects. Hydroxychloroquine is an antimalarial drug, with T cell modulating function. This study was undertaken to assess the safety, efficacy and tolerability of Hydroxychloroquine in Alopecia areata compared to betamethasone oral mini pulse (OMP) therapy. Methods: 60 patients with alopecia areata were randomized into two groups of 30 each. Control group received tab. betamethasone 5 mg/day on two consecutive days of week for 12 weeks and Study group received tab. hydroxychloroquine 200 mg/day for 12 weeks. They were followed-up for further 12 weeks. Scale of alopecia tool, dermatology life quality index and global assessment at baseline, 12 weeks and 24 weeks were used to assess the outcome.Results: 94 patients were screened and 60 patients were included. All patients completed the study. At the end of 12 weeks, there was a statistically significant reduction in SALT and DLQI scores in both control and study groups. But at the end of 24 weeks, the study group showed an increase in the scores. Relapses were more in the study group. No significant difference in the incidence of adverse events was noted between the two groups.Conclusions: Hydroxychloroquine 200 mg/day is less efficacious in the management of alopecia areata in comparison to betamethasone oral mini pulse therapy.
