ABSTRACTObjective. A. phagocytophilum, an obligate intracellular pathogen, is a well-known agent causing granulocytic infections in both animals and humans. The purpose of the present study was to describe clinical course and consequences of Canine Granulocyctic Anaplasmosis among dogs in Aydin province, Turkey with special reference to hematological alterations and possible interpretations of doxycycline+chloroquine dual therapy. Materials and methods. A controlled clinical trial was carried out on 14 dogs referred and diagnosed as Canine Granulocyctic Anaplasmosis within Snap 4dx test. Relevant haematological data were recorded before (day 0) and after treatment (day 30) in both groups. Group I (n=7) were adminestered doxycycline (10 mg/kg q 12 h via oral route for 14 days) and chloroquine (2.5 mg/kg q 12 h for 14 days) and group II (n=7) received only doxycycline (10 mg/kg q 12 h for 14 days via oral route) therapy. Results. Doxycycline treatment hasten resolution of clinical signs in all dogs in about 2 to 7 days. There was no statistically significant differences among hematological variances detected (p>0.05). Conclusions. It may suggest that in conjunction with doxycycline chloroquine may have helped to speed up relevant clinical signs of CGA.RESUMENObjetivo. A. phagocytophilum, un patógeno intracelular obligado, es un agente ampliamente conocido que causa infecciones granulocíticas tanto en animales como en humanos. El propósito del presente estudio fue describir la evolución clínica y las consecuencias de la Anaplasmosis Granulocítica Canina en perros de la provincia de Aydin, Turquía, con especial referencia a las alteraciones hematológicas y a las posibles interpretaciones de una terapia dual de doxicilina+cloroquina. Materiales y métodos. Se realizó un estudio clínico controlado en 14 perros remitidos y diagnosticados con Anaplasmosis Granulocítica Canina usando de una prueba Snap 4dx. Se registraron datos hematológicos pertinentes antes (día 0) y después del tratamiento (día 30) en ambos grupos. Al Grupo I (n=7) se le administró doxicilina (10 mg/kg q 12 h por vía oral durante 14 días) y cloroquina (2.5 mg/kg q 12 h durante 14 días), mientras que el Grupo II (n=7) recibió una terapia únicamente con doxicilina (10 mg/kg q 12 h por vía oral durante 14 días). Resultados. La doxicilina aceleró la resolución de los signos clínicos en todos los perros en un periodo de aproximadamente 2 a 7 días. No se detectaron diferencias estadísticas significativas entre las variaciones hematológicas (p>0.05). Conclusiones. Lo anterior puede sugerir que, conjuntamente con la doxicilina, la cloroquina puede haber ayudado a acelerar los signos clínicos pertinentes de la Anaplasmosis Granulocítica Canina (AGC).

The aim of this in-vivo study was to evaluate/compare the clinical periodontal parameters in patients with true combined endo-perio lesions (EPL), treated with gutta-percha (GP) and mineral trioxide (MTA) as an obturation material alone and with addition of bone grafting in such lesions. 120 Saudi patients (mean age = 41yrs) diagnosed with true combined EPL participated in this study. Group I (control group, n = 30) was treated with conventional endodontic treatment using GP for obturation. Group II (n = 30) was treated with conventional endodontic treatment using MTA for obturation. Group III (n = 30) was treated with conventional endodontic treatment using GP for obturation + grafting procedure to fill the bony defect. Group IV (n = 30) was treated with conventional endodontic treatment using MTA for obturation + grafting procedure to fill the bony defect. Clinical parameters (Pocket depth (PD); Clinical attachment loss (CAL); keratinized tissue width (KTW); gingival phenotype (G.Ph.) and Cone Beam Computed Tomography Periapical Index (CBCTPAI)) were recorded and compared at baseline, 3, 6, 12 months’ interval. For the groups III and IV, CBCTPAI showed significant difference (p < 0.0001) with the other groups at 6 months and 1-year interval. The group with MTA + bone graft showed 76% and 90% patients with 0 score at 6 months and 1-year follow-up, respectively. Comparison of mean values of PD among study groups at 3 months, 6 months and 1 year showed significant difference at 3 months, whereas the mean PD values of subjects in GP + bone graft showed significantly higher PD values than other 3 groups (p = 0.025). Use of GP and MTA for root canal obturation along with periodontal therapy and bone augmentation helps in resolving complex endo-perio lesions. Bone grafting in addition to obturation with MTA was found to be the best treatment strategy in management of EPL cases and is recommended for clinicians who are treating EPL patients.

Dr. Rothman of Haverhill, MA questioned the short duration of antimicrobial treatment and use of oral route for the patient with osteomyelitis presented by Bennett in PIR 1:153, November 1979. He noted that the traditional regimen for osteomyelitis calls for six weeks of intravenous antimicrobial therapy. Dr. Bennett quotes from Telzlaff et al (J Pediatr 92:485, 1978). In this report good results were found when antimicrobial regimens for patients with osteomyelitis and suppurative arthritis consisted of a brief initial period of parenteral therapy of only one to seven days followed by oral antimicrobial therapy begun when there was a definitive decrease in clinical signs of inflammation and continued for three weeks or longer. It is important to note that surgical drainage of pus was carried out, that antimicrobial blood levels were obtained after initiation of oral therapy to ensure adequate levels, that therapy was continued until all signs and symptoms had subsided, that there was no evidence of cortical destruction or sequestrum formation on roentgenogram, and the erythrocyte sedimentation rate was less than 20 mg/hr. When these conditions are met it is clear that oral therapy can be an adequate substitute for prolonged intravenous therapy for osteomyelitis in children.

Abstract Background: There were large outbreaks of high pathogenicity avian influenza (HPAI) caused by clade 2.3.4.4e H5N6 viruses in the winter of 2016–2017 in Japan, which caused large numbers of deaths among several endangered bird species including cranes, raptors, and birds in Family Anatidae. In this study, susceptibility of common Anatidae to a clade 2.3.4.4e H5N6 HPAI virus was assessed to evaluate their potential to be a source of infection for other birds. Eurasian wigeons (Mareca penelope), mallards (Anas platyrhynchos), and Northern pintails (Anas acuta) were intranasally inoculated with 106, 104, or 102 50% egg infectious dose (EID50) of clade 2.3.4.4e A/teal/Tottori/1/2016 (H5N6). Results: All birds survived for 10 days without showing any clinical signs of infection. Most ducks inoculated with ≥104 EID50 of virus seroconverted within 10 days post-inoculation (dpi). Virus was mainly shed via the oral route for a maximum of 10 days, followed by cloacal route in late phase of infection. Virus remained in the pancreas of some ducks at 10 dpi. Viremia was observed in some ducks euthanized at 3 dpi, and ≤106.3 EID50 of virus was recovered from systemic tissues and swab samples including eyeballs and conjunctival swabs. Conclusions: These results indicate that the subject duck species have a potential to be a source of infection of clade 2.3.4.4e HPAI virus to the environment and other birds sharing their habitats. Captive ducks should be reared under isolated or separated circumstances during the HPAI epidemic season to prevent infection and further viral dissemination.

Abstract Background: This is a five years follow-up report of some of the new devices for graft fixation. A two years follow-up data was published previously. As there were no statistically or clinically relevant differences in the results two years postoperatively, we hypothesize that after five years of follow-up there is no difference in the outcome after either cross-pin or absorbable interference screw fixation in ACL (anterior cruciate ligament) reconstruction with hamstring tendon autografts.Methods: 120 patients were randomized into four different groups (30 each) for ACL reconstruction with hamstring tendons: group I femoral Rigidfix cross-pin and Intrafix tibial extension sheath with a tapered expansion screw; group II Rigidfix femoral and BioScrew interference screw tibial fixation; group III BioScrew femoral and Intrafix tibial fixation; group IV BioScrew fixation into both tunnels. The evaluation methods were clinical examination, knee scores, and instrumented laxity measurements. Results: In this 5 years follow-up there were 102/120 (85%) patients available, but only 77 (64,2%) attended the clinical examinations. No significant difference between the groups in the clinical results was detected. There was a significant difference in additional procedures between the 2 and 5 years follow-up, group I had six additional procedures between the 2 and 5 years follow-up (P=.041). Conclusion: There was a statistically significant difference in the additional procedures, most in group I (six). None of these procedures found problems with the ACL graft. Other statistically or clinically significant differences in the 5 years follow-up results were not found. Study design: Randomized controlled clinical trial; Level of evidence, 1.Trial registration: ISRCTN registry with study ID ISRCTN34011837. Retrospectively registered 17.4.2020.

This research aimed to evaluate mandibular movements in children with and without signs and symptoms of temporomandibular dysfunction. The sample taken consisted of 99 children aged 3 to 5 years distributed in two groups: I - Absence of signs and/or symptoms of TMD (25 girls/40 boys); II - Presence of signs and symptoms of TMD (16 girls/18 boys). The symptoms were evaluated through an anamnesis questionnaire answered by the child's parents/caretakers. The clinical signs were evaluated through intra- and extraoral examination. Maximum mouth opening and left/right lateral movements were measured using a digital caliper. The maximum protrusive movement was measured using a millimeter ruler. The means and standard deviations for maximum mouth opening in Group I and Group II were 40.82mm±4.18 and 40.46mm±6.66, respectively. The values found for the left lateral movement were 6.96mm±1.66 for Group I and 6.74mm±1.55 for Group II, while for the right lateral movement they were 6.46mm±1.53 and 6.74mm±1.77. The maximum protrusion movements were 5.67mm±1.76 and 6.12mm±1.92, in Groups I and II, respectively. The mandibular movement ranges neither differed statistically between groups nor between genders.

ABSTRACT: A glycoprotein E-deleted Brazilian bovine herpesvirus 1 (BoHV-1gEΔ) was tested regarding to safety and immunogenicity. Intramuscular inoculation of young calves with a high virus dose did not result in clinical signs or virus shedding during acute infection or after dexamethasone administration. Calves vaccinated once IM (group I) or subcutaneously (group II) with live BoHV-1gEΔ or twice with inactivated virus plus aluminum hydroxide (group IV) or Montanide™ (group V) developed VN titers of 2 to 8 (GMT:2); 2 to 4 (GMT:1.65); 2 to 16 (GMT:2.45) and 2 to 128 (GMT:3.9), respectively. All BoHV-1gEΔ vaccinated calves remained negative in an anti-gE ELISA. Lastly, six young calves vaccinated with live BoHV-1gEΔ and subsequently challenged with a virulent BoHV-1 strain shed less virus and developed only mild and transient nasal signs comparing to unvaccinated calves. Thus, the recombinant BoHV-1gEΔ is safe and immunogenic for calves and allows for serological differentiation by a gE-ELISA test.

This Randomised controlled clinical trial was undertaken to determine the suitable time of catheter removal after urogenital prolapse surgery in order to reduce the catheter related UTI and its long term sequel. Method: Total 80 patients undergoing vaginal hysterectomy with pelvic floor repair were enrolled and randomised into two equal groups by lottery method. Trans-urethral catheter was removed on 2nd & 5th post operative day in group I (n=40) and in group II (n=40) respectively. Post   voidal residual urine volume before operation and after removal of catheter was measured in   all patients by ultrasound scanning. Re-catheterisation was done for three more days if residual volume > 200ml after removal of catheter. Urine samples were taken before removal of catheter and send for routine microscopic examination and culture & sensitivity test to detect UTI.Results: Removal of catheter on 2nd post-operative day lead to significant reduction of rate of UTI. The rate of UTI following removal of catheter was 7.5% versus 42.5% in group I and in group II (p<0.001). But need for recatheterisation was significantly higher in group I (15%) than in group II (2.5%). The mean duration of catheterisation was 47.63 (±0.628) and 119.35 (±0.864) hours in group I and group II respectively. Majority of the patients in group I did not  require prolongation of catheterisation. Mean duration of hospital stay after operation was 5 days in group I and 7.95 days in group II (p<0.001). Conclusion: Short period catheterisation is associated with lower rate of UTI and shorter hospital stay. Disadvantages of prolonged catheterisation outweigh the advantages. Therefore removal of the catheter on the 2nd post-operative day after genital prolapse surgery is preferable than 5 days catheterization DOI: http://dx.doi.org/10.3329/bjog.v26i2.13782 Bangladesh J Obstet Gynaecol, 2011; Vol. 26(2) : 68-71

This study aimed to evaluate the efficacy and toxicity of tenofovir (TDF) and TDF combined with emtricitabine (TDF/FTC) in patients with mild to moderate COVID-19 infections. We conducted a randomized, double-blind, placebo-controlled clinical trial in patients with clinical suspicion of mild to moderate respiratory infection caused by SARS-CoV-2 who were treated at an outpatient clinic. Patients were randomly recruited to take 10 days of TDF (300 mg/day), TDF (300 mg/day) combined with FTC (200 mg/day) or placebo Vitamin C (500 mg/day). The primary parameter was the score of symptoms and predictive signs of COVID-19, assessed on the seventh day of patient follow-up. From a total of 309 patients with clinical suspicion of SARS-CoV-2, 227 met the inclusion criteria and were randomly distributed into the following groups: (a) 75 (one did not initiate treatment) in the TDF group; (b) 74 in the TDF combined with FTC group; and (c) 77 in the Vitamin C group (placebo). Of the 226 patients, 139 (62%) were positive for SARS-CoV-2. Fever (37.8oC), ageusia or dysgeusia, anosmia or dysosmia, and two or more clinical symptoms or signs were significantly associated with SARS-CoV-2 infection. There was no significant change in clinical score based on clinical symptoms and signs between treatment groups. Patients with mild to moderate infection by SARS-CoV-2 had higher concentrations of G-CSF, IL-1β, IL-6 and TNF-α compared to patients without infection. Patients with mild to moderate respiratory infection, with fever (37.8oC), loss of smell, loss of taste and two or more symptoms, have a better prediction for the diagnosis of COVID-19. Patients with SARS-CoV-2 showed higher and more persistent proinflammatory cytokines profile compared to patients not infected with SARS-CoV-2. Pharmacological intervention with TDF or TDF combined with FTC did not change the clinical signs and symptoms score in mild to moderate respiratory infection in patients with SARS-CoV-2 compared to the Vitamin C group (placebo).

Microsporidia are ubiquitous obligate intracellular pathogens of animals. These parasites often infect hosts through an oral route, but little is known about the function of host intestinal proteins that facilitate microsporidia invasion. To identify such factors necessary for infection by Nematocida parisii, a natural microsporidian pathogen of Caenorhabditis elegans, we performed a forward genetic screen to identify mutant animals that have a Fitness Advantage with Nematocida (Fawn). We isolated four fawn mutants that are resistant to Nematocida infection and contain mutations in T14E8.4, which we renamed aaim-1 (Antibacterial and Aids invasion by Microsporidia). Expression of AAIM-1 in the intestine of aaim-1 animals restores N. parisii infectivity and this rescue of infectivity is dependent upon AAIM-1 secretion. N. parisii spores in aaim-1 animals are improperly oriented in the intestinal lumen, leading to reduced levels of parasite invasion. Conversely, aaim-1 mutants display both increased colonization and susceptibility to the bacterial pathogen Pseudomonas aeruginosa and overexpression of AAIM-1 reduces P. aeruginosa colonization. Competitive fitness assays show that aaim-1 mutants are favoured in the presence of N. parisii but disadvantaged on P. aeruginosa compared to wild type animals. Together, this work demonstrates how microsporidia exploits a secreted protein to promote host invasion. Our results also suggest evolutionary trade-offs may exist to optimizing host defense against multiple classes of pathogens.

Background Neurodegenerative diseases are sporadic hereditary conditions characterized by progressive dysfunction of the nervous system. Among the symptoms, vestibulopathy is one of the causes of discomfort and a decrease in quality of life. Hereditary spastic paraplegia is a heterogeneous group of hereditary degenerative diseases involving the disorder of a single gene and is characterized by the progressive retrograde degeneration of fibers in the spinal cord. Objective To determine the benefits of vestibular rehabilitation involving virtual reality by comparing pre intervention and post intervention assessments in individuals with hereditary spastic paraplegia. Methods In this randomized controlled clinical trial from the Rebec platform RBR-3jmx67 in which allocation concealment was performed and the evaluators be blinded will be included. The participants will include 40 patients diagnosed with hereditary spastic paraplegia. The interventions will include vestibular rehabilitation with virtual reality using the Wii® console, Wii-Remote and Wii Balance Board (Nintendo), and the studies will include pre- and post intervention assessments. Group I will include twenty volunteers who performed balance games. Group II will include twenty volunteers who performed balance games and muscle strength games. The games lasted from 30 minutes to an hour, and the sessions were performed twice a week for 10 weeks (total: 20 sessions). Results This study provides a definitive assessment of the effectiveness of a virtual reality vestibular rehabilitation program in halting the progression of hereditary spastic paraplegia, and this treatment can be personalized and affordable. Conclusion The study will determine whether a vestibular rehabilitation program with the Nintendo Wii® involving virtual reality can reduce the progressive effect of hereditary spastic paraplegia and serve as an alternative treatment option that is accessible and inexpensive. Rebec platform trial: RBR-3JMX67.
