Abstract Food allergies and food intolerances are clinically difficult to discriminate. Most often, along with cutaneous adverse food reactions or CAFR, they are classified as adverse food reactions, whose causes are numerous, including toxic compounds. Eighteen indoor-housed domestic cats with evident clinical symptoms related to CAFR (drooling, back and neck intense itching, neck eczema, chronic conjunctivitis and stomatitis) involving skin lesions were studied. Cytological evaluations of ear, skin and gingival swabs revealed an increased turnover of keratinocytes while the oxytetracycline ELISA determination showed an unexpected high amount of oxytetracycline in all cats at the first visit. All cats were then randomly assigned to receive a standard (SD group) or a nutraceutical diet (ND group) for 60 days. In the ND group a significant reduction of the mean serum concentration of oxytetracycline, pruritus intensity and skin lesion severity (**p<0.01, ***p<0.001, and ***p<0.001, respectively) was observed after 60 days, and associated with a significant improvement in the clinical picture. Although a direct correlation between oxytetracycline presence within cat sera and CAFR-related symptoms has never been described, this study highlights the benefit of a specific nutraceutical diet supplementation in improving clinical symptoms and skin lesions in cats with CARF.

Abstract Background and Aims The prevalence of central vein stenosis (CVS) in patients on hemodialysis (HD) is difficult to be assessed directly. This is mainly caused by the variety of clinical signs and the high frequency of asymptomatic CVS. Aim: to assess the frequency of occurrence of various CVS forms in HD patients. Method The retrospective observational study is based on the results of treatment of 1865 HD patients who underwent diagnostic and therapeutic procedures on vascular access in our center. In case of vascular access dysfunction, patients were examined according to a local protocol: ultrasound of the peripheral (to exclude lesion of peripheral AVF segments) and central veins (over the available length), followed with CT-angiography or percutaneous angiography, if necessary. Results AVF/AVG dysfunction was observed in 29.4% of patients (549 of 1865). 211 patients were diagnosed with CVS. The prevalence of CVS was 11.3% (211 of 1865) among all HD patients and 38.4% (211 of 549) in patients with AVF dysfunction. Among patients with CVS, 37% (78 of 211) had vein lesions without clinical symptoms or with minimal manifestations (a tendency to decrease KT/V). The prevalence of asymptomatic CVS was 4.2% (78 of 1865) in the general population of HD patients and 14.2% (78 of 549) in patients with AVF dysfunction. In case of asymptomatic CVS it was detected by an ultrasound examination during CVC implantation (N=38), during unsuccessful attempts to implant CVC (N=29), in the case of recurrent AVF thrombosis without underlying peripheral segments lesion (N=9) or during echocardiography (N=2). The prevalence of asymptomatic CVS among patients without AVF dysfunction was 5.9% (78 of 1316). True prevalence of subclinical CVS among HD patients without obvious signs of AVF dysfunction may vary widely. A total of 48.8% (103 of 211) of all CVS cases were treated. At the same time, in 10.7% (11 of 103) of cases, patients did not present symptoms of CVS, and surgery was performed due to recurrent AVF thrombosis without damage of the peripheral parts of AVF. Patients with clinically manifest CVS who received endovascular interventions had a significantly higher risk of AVF loss compared to patients with asymptomatic CVS: HR=2.566 [95% CI 1.706; 3.86], log rank p&lt;0.0001. However, patients with an asymptomatic CVS had a higher risk of AVF function loss compared to the general HD population (HR=2,051 [95% CI 1,243; 3,384], log rank p= 0.0004) – fig. 1. The use of CVC is a known risk factor of CVS development. We analyzed the relationship of CVS risk with multiply CVC placements and catheter dwell time using the Cox proportional hazards regression model (fig. 2). In the univariate model, a greater No of CVCs as well as longer time in place increased the risk of CVS. In the multivariate model (χ2=105.516, df=2, p&lt;0.0001), catheter dwell time was no longer associated with an increased risk of CVC, while the mean number of inserted catheters remained an important risk factor. Conclusion The prevalence of both symptomatic and asymptomatic forms of CVS in HD patients is high. Patients with vascular access dysfunction should be carefully examined to identify the asymptomatic CVS. The mean No of catheterizations is a more important risk factor of CVS than longer catheter dwell time.

Abstract Objectives This study aims to investigate the efficacy of curcumin-piperine co-supplementation on disease duration, severity and clinical symptoms, and inflammatory mediators in patients with coronavirus (COVID-19). Trial design This is a randomized, placebo-controlled, double-blind, parallel arm clinical trial. Participants All patients aged 20-75 years with the diagnosis of Covid-19 based on the PCR test. The exclusion criteria will include an age less than 20 and more than 75 years, current use of warfarin or other anticoagulant drugs, and the presence of sensitivity to herbal products such as turmeric and pepper. This study will be conducted in academic hospitals affiliated to Isfahan University of Medical Sciences, Isfahan, Iran. Intervention and comparator Fifty outpatients will be randomly allocated in a ratio of 1:1 to receive a capsule of curcumin-piperine containing 500 mg curcumin plus 5 mg piperine or matching placebo containing 505 mg maltodextrin twice a daily, after lunch and dinner, over a period of 2 weeks. Similarly, 50 inpatients who are admitted to hospital wards excluding intensive care unit (ICU) will be randomly assigned in a ratio of 1:1 to receive a capsule curcumin-piperine or matching placebo (provided by the Sami Labs company) twice a daily, after lunch and dinner, over a period of 2 weeks. Main outcomes The main outcomes of this study are the efficacy of curcumin-piperine on coronavirus disease’s clinical symptoms, duration, severity, and inflammatory mediators after 2 weeks of curcumin-piperine co-supplementation. Randomisation Randomization sequences will be generated with the use of a random-number table with a permuted block design (block size of 4) and stratification according to the gender variable (male vs. female). These sequences will be prepared by an independent statistician and will be kept in opaque, sealed, numbered envelopes which will be opened only at the time of enrollment. The allocation ratio in intervention and control groups is 1:1. Researchers and all patients will be unaware of the study-group assignment until the completion of data analyses. Blinding (masking) This study is a double-blind clinical trial (participant, researcher). The curcumin-piperine and placebo supplements are packaged in similar numbered drug containers, and the researcher and all patients will be unaware of the study assignment until the end of the study.

A prospective double-blind study was conducted to compare the anti-emetic efficacy of ondansetron and droperidol in preventing postoperative emesis following strabismus surgery. A sample size of 213 patients was divided into three equal groups to receive ondansetron 150 μg/kg (Group A), ondansetron 75 μg/kg (Group B), or droperidol 75 fig/kg (Group C). All patients received a standardized anaesthetic technique. All episodes of emesis, recovery time, and time to tolerating oral fluids were recorded. The incidence of emesis during 24 hours was Groups A and B 19.7%, and Group C 28.2%. The lower incidence of emesis recorded by the ondansetron groups compared with the droperidol group was not statistically significant. Ondansetron at 75 μg/kg was as effective as 150 μg/kg in reducing emesis when compared with droperidol. Mean time to discharge from the recovery room was 75.3 minutes (Group A), 44.4 minutes (Group B), and 41.0 minutes (Group C). The mean time to tolerating oral fluids was 356.5 minutes (Group A), 402.8 minutes (Group B), and 378.1 minutes (Group C). There was no statistical difference in discharge times from recovery or time to tolerating oral fluids in any of the three groups.

Background. Weight regain after laparoscopic sleeve gastrectomy (LSG) is nowadays a growing concern. Sleeve dilatation and loss of food restriction is considered the main mechanism. The placement of a silicon ring around the gastric tube seems to give benefits in the short term. We report the results of a randomized study comparing LSG and laparoscopic banded sleeve gastrectomy (LBSG) over a 4-year follow-up. Objectives. To evaluate the efficacy of banded sleeve gastrectomy compared to standard sleeve in the midterm. Methods. Between 01/2014 and 01/2015, we randomly assigned 50 patients to receive one of the two procedures. Patients’ management was exactly the same, apart from the band placement. We analyzed differences in weight loss, operative time, complication rate, and mortality, with a median follow-up of 4 years. Results. Twenty five patients were assigned to receive LSG (Group A) and 25 LBSG (Group B). The mean preoperative BMI (body mass index) was 47.3 ± 6.58 kg/m2 and 45.95 ± 5.85 kg/m2, respectively. There was no significant difference in the operative time. No intraoperative or postoperative complications occurred. At 12-month follow-up, the mean BMI was 29.72 ± 4.40 kg/m2 in Group A and 27.42 ± 4.47 kg/m2 in Group B (p=0.186). After a median follow-up of 4 years, the mean BMI in Group B was significantly lower than Group A (24.10 ± 4.52 kg/m2 vs 28.80 ± 4.62 kg/m2; p=0.00199). Conclusions. LBSG is a safe procedure, with no impact on postoperative complications. The banded sleeve showed a significant greater weight loss in the midterm follow-up. Considering the issue of weight regain observed after LSG, the placement of a perigastric ring during the first procedure may be a strategy to improve the results. This trial is registered with NCT04228185.

Background: Induction of labour can be defined as “Artificial initiation of uterine contractions before the onset of spontaneous labour, after the period of viability, by any methods, for purpose of vaginal delivery.” The key factor for a successful induction is the status of cervix, its form, consistency and dilatation which is determined by the Bishop score. In case of unfavourable cervix or in the pregnancies remote from the term; prostaglandins are more effective than any other method of induction. Introduction of misoprostol, PGE1 analogue, for the induction of labour in 1993 and its approval for clinical use by ACOG (American College of Obstetrics and Gynecology) in 1999 has been the most significant advancement. It is the latest drug for induction of labour which is cheap and stable at room temperature and is being used worldwide in different doses and by various routes. We compared the most commonly preferred two routes; vaginal and oral in terms of success of induction and noted the adverse events and side effects in both routes.Methods: This was a prospective comparative study carried out at SBKSMIRC (Shrimati Bhikhiben Kanjibhai Shah Medical Institute and Research Centre), Dhiraj general hospital, Vadodara, Gujarat, 200 patients who required induction of labour were recruited after applying inclusion and exclusion criteria and were randomly divided in two groups- Group A meant to receive 50µg oral misoprostol, Group B - meant to receive 25µg vaginal misoprostol repeated 4 hourly up to maximum of five doses. Progress of labour was charted on the partograph. The mean induction delivery interval, mode of delivery, maternal and neonatal outcomes and complications were observed.Results: The mean induction to delivery interval was significantly less in vaginal group than oral (23.3±12.4 hours in oral vs. 17.3±10 hours in vaginal). Vaginal delivery and cesarean section rates were comparable in both groups (76% in Group A vs. 72% in Group B for vaginal delivery, 18% vs. 20% for Cesarean section, respectively). 58% patients in Group A required more than two doses as compared to 39% in group B, though the difference was statistically not significant. Significant number of patients required added oxytocin administration in Group A (72%). No major complications or adverse events were observed. Neonatal hyperbilirubinemia was seen more in Group A.Conclusions: Both Oral misoprostol in a dose of 50μg and vaginal misoprostol 25 μg every four hours, to a maximum of five doses, have the potential to induce labour safely and effectively. The vaginal route however is beneficial in effecting delivery in lesser time with few numbers of doses as compared to oral route.

Background:Cognitive dysfunction is one of the common clinical symptoms in multiple sclerosis (MS), but there is no effective treatment for it.Objective:The aim of this study was to evaluate the effect of rivastigmine in treating memory and cognitive dysfunction in MS.Methods:A single-center double-blind placebo-controlled randomized clinical trial conducted from October 2005 to February 2007. Sixty definite MS patients with cognitive impairment age 16 to 54 years were randomly allocated to receive a 12-week treatment course of either rivastigmine (1.5 mg once a day increment over 4 weeks to 3 mg twice daily) or placebo. Response to treatment was assessed by the Wechsler Memory Scale (WMS) at baseline and 12 weeks after start of therapy.Results:A slight, but significant memory improvement occurred in both groups. Of the 30 patients treated with rivastigmine, the mean (SD) WMS general memory score increased from 60.3 (4.2) at baseline to 64.9 (5.3) at the end of study period (P<0.001). Correspondingly, in the 30 patients treated with placebo, the mean (SD) WMS general memory score increased from 60.5 (4.9) to 64.5 (3.7) (P < 0.001). The average WMS general memory score at the end of trial did not changed between rivastigmine and placebo group (mean difference, 0.4; 95% CI, -2.0, 2.8).Conclusion:No significant differences were seen between rivastigmine and placebo on the mean (SD) WMS general memory score. A larger multicenter study of rivastigmine in MS is warranted in order to more definitely assess the efficacy of this intervention.

Objectives: We evaluated the association between pathological acidic laryngopharyngeal reflux (LPR) events and chronic pharyngitis in patients with Reinke's edema. Methods: We performed a prospective controlled study in 20 consecutive patients with Reinke's edema without pathological acidic LPR events (group A) and 40 consecutive patients with Reinke's edema with both clinical symptoms and 24-hour pH-metry suggesting acidic LPR (group B). The severity of acidic LPR was assessed by use of the Reflux Finding Score (RFS), the Reflux Symptom Index (RSI), and dual antimony probe 24-hour pH-metry. The patients were evaluated for the presence of chronic pharyngitis by clinical examination and biopsy specimens taken from the posterior pharyngeal wall. The χ2 test was used to compare the groups for the presence of pharyngitis. In group B, the RSI, the RFS, and the total duration and number of acidic LPR events on 24-hour pH-metry were compared between patients with and without concomitant pharyngitis by use of the Mann-Whitney test. Results: Five patients of group A and 20 patients of group B had chronic pharyngitis. Therefore, more patients with Reinke's edema and clinical signs of LPR tended to have chronic pharyngitis than did those with Reinke's edema and no clinical signs of LPR, but the difference was not statistically significant (p = 0.064; odds ratio, 3.0; 95% confidence interval, 0.9 to 9.8). Among group B patients, those with pharyngitis had significantly more acidic LPR events (p < 0.001) and a greater exposure time to gastric fluid (p = 0.008) than did those without pharyngitis. Their RFS and RSI did not differ significantly (p = 0.692 and p = 0.914, respectively). Conclusions: Only in the subgroup of patients with Reinke's edema and LPR was there a statistically significant correlation between the pH probe results and the incidence of clinical pharyngitis. Awareness should increase among physicians about addressing chronic pharyngitis in therapy for acidic LPR and/or Reinke's edema.

Background This study evaluates an active search strategy for leprosy diagnosis based on responses to a Leprosy Suspicion Questionnaire (LSQ), and analyzing the clinical, immunoepidemiological and follow-up aspects for individuals living in a prison population. Methods A cross-sectional study based on a questionnaire posing 14 questions about leprosy symptoms and signs that was distributed to 1,400 prisoners. This was followed by dermatoneurological examination, anti-PGL-I serology and RLEP-PCR. Those without leprosy were placed in the Non-leprosy Group (NLG, n = 1,216) and those diagnosed with clinical symptoms of leprosy were placed in the Leprosy Group (LG, n = 34). Findings In total, 896 LSQ were returned (64%), and 187 (20.9%) of the responses were deemed as positive for signs/symptoms, answering 2.7 questions on average. Clinically, 1,250 (89.3%) of the prisoners were evaluated resulting in the diagnosis of 34 new cases (LG), based on well-accepted clinical signs and symptoms, a new case detection rate of 2.7% within this population, while the NLG were comprised of 1,216 individuals. The confinement time medians were 39 months in the LG while it was 36 months in the NLG (p>0.05). The 31 leprosy cases who responded to the questionnaire (LSQ+) had an average of 1.5 responses. The symptoms “anesthetized skin area” and “pain in nerves” were most commonly mentioned in the LG while “tingling, numbness in the hands/feet”, “sensation of pricks and needles”, “pain in nerves” and “spots on the skin” responses were found in more than 30% of questionnaires in the NLG. Clinically, 88.2% had dysesthetic macular skin lesions and 97.1% presented some peripheral nerve impairment, 71.9% with some degree of disability. All cases were multibacillary, confirming a late diagnosis. Anti-PGL-I results in the LG were higher than in the NLG (p<0.0001), while the RLEP-PCR was positive in 11.8% of the patients. Interpretation Our findings within the penitentiary demonstrated a hidden prevalence of leprosy, although the individuals diagnosed were likely infected while living in their former communities and not as a result of exposure in the prison. The LSQ proved to be an important screening tool to help identify leprosy cases in prisons.

Aims: To evaluate and compare the efficacy of Hilo® and Daflon® 500 mg, in the treatment of hemorrhoids. Study Design: It is a multicentric, randomized, comparative clinical trial conducted for the period of 15 days. Place and Duration of Study: Janta Hospital and Maternity Centre, Varanasi; King George Memorial Hospital, Lucknow; Vijan Hospital and Research Centre, Nasik and Santosh Hospital, Bangalore between May 2018 and December 2019. Methodology: 201 patients were screened and 200 patients with hemorrhoids (proctoscopy proven Grade I to III) were randomly assigned to receive either Hilo® capsules (n = 99) or Daflon® 500 mg tablets (n = 101). Assessment of hemorrhoidal symptoms was carried out in all patients on Day 7 and Day 15. Proctoscopic examination was carried out before the start of treatment i.e. on day 0 and at the end of treatment duration i.e. on day 15. Results: The patients treated with Hilo® showed a statistically significant improvement in the clinical symptoms of bleeding, pain, itching, soiling, tenesmus, irritation after defecation and constipation on day 7 and day 15 as compared to baseline. The “mean total symptom score” reduced by 4.55 ± 2.07 vs 3.44 ± 2.00; P < .0001 on day 7 and 7.56 ± 2.40 vs 6.22 ± 2.55; P < .0001 on day 15 in the patients treated with Hilo® and Daflon® respectively. In Hilo® Group, 82.83% of patients assessed that the treatment with Hilo® made them ‘A lot better’ as compared to only 48.51% in Daflon® group. In the Hilo® group 20.2% of patients’ treatment outcome was assessed as ‘Excellent’ by the investigators as compared to only 0.99% of patients in Daflon® group. No major adverse events were reported in the study with the use of either product. Conclusion: Hilo® is found to provide better reduction in clinical symptoms of patients suffering from hemorrhoids as compared to Daflon®.

This study was carried out to evaluate the efficacy of vaccination of layer chickens with inactivated FC bacterin prepared from local Egyptian strains of Pasteurella multocida (P. multocida). A total of 200 layer chickens were divided into 5 equal groups, 40 for each. At the age of 6 weeks, chickens in groups (A) and (B) were vaccinated with P. multocida serotypes A:1 and A:3, respectively, booster doses were given after 3 weeks (9 weeks old) and challenge was done with virulent serotypes A:1 and A:3 at 2 weeks later (11 weeks old). Chickens in groups (C) and (D) were not vaccinated, only challenged with P. multocida serotype A:1 and A:3, respectively. Birds in group (E) were kept as non-vaccinated and non-challenged. Blood samples were collected weekly from all groups for humoral immune response. All the birds were kept under observation for signs, mortalities, lesions and re-isolation of challenging organism and for histopathological examination. Results of the mean Enzyme Linked Immuno-Sorbent Assay (ELISA) revealed that the highest level was at 5 weeks post vaccination as the titers reached to 3970 in group (A) and 3905 in group (B). The clinical signs, mortality rate and lesions were mild in the vaccinated birds while severe lesions were in non-vaccinated and challenged birds. The protection rates were 85 % and 80 % in groups (A) and (B); respectively, while 10 % and 20 % in groups (C) and (D); respectively. The re-isolation rates of P. multocida after challenge were 95 % and 90 % in non-vaccinated-challenged birds with P. multocida serotypes A:1 and A:3; respectively, while they were 25 % and 15 % in vaccinated-challenged groups with P. multocida serotypes A:1 and A:3; respectively. Histopathological examination of P. multocida vaccinated-challenged birds revealed mild to no microscopic lesions when compared with non-vaccinated challenged chickens. In conclusion, the prepared FC inactivated bacterin from the local Egyptian predominant P. multocida serovars proved efficacy and protection of layer chickens. Key words: Pasteurella multocida; chickens; immunization; protection; Egypt UČINKOVITOST CEPLJENJA KOKOŠI NESNIC Z INAKTIVIRANO BAKTERIJO KOLERE PERJADI, PRIPRAVLJENE IZ LOKALNIH EGIPTOVSKIH SEVOV BAKTERIJE Pasteurella multocida Povzetek: Raziskava je bila izvedena z namenom ocenitve učinkovitosti cepljenja kokoši nesnic z inaktivirano bakterijo FC, pripravljeno iz lokalnih egiptovskih sevov bakterije Pasteurella multocida (P. multocida). Skupno 200 kokoši nesnic je bilo razdeljenih v 5 enakih skupin. V vsaki skupini je bilo 40 kokoši. Pri 6 tednih smo kokoši v skupinah A in B cepili s serotipoma P. multocida A:1 in A:3, po 3 tednih, ko so bile živali stare 9 tednov, so dobile poživitvene doze cepiva. Po dveh tednih (v starosti 11 tednov) so bile kokoši okužene z virulentnima serotipoma A:1 in A:3. Piščanci v skupinah C in D niso bili cepljeni temveč samo okuženi s serotipoma A:1 in A:3. Kokoši v skupini E niso bile niti cepljene, niti okužene. Vzorci krvi so bili odvzeti pri vseh skupinah tedensko za preverjanje humoralnega imunskega odziva. Vse kokoši smo stalno opazovali in beležili prisotnost bolezenskih znakov, različnih ran in umiranje kokoši. Pri poginulih kokoših smo osamili bakterije ter opravili histopatološki pregled. Rezultati encimsko-imunskega testa (ELISA) so pokazali da je bila najvišja stopnja zaščite dosežena 5 tednov po cepljenju, saj so titri dosegli 3970 v skupini A in 3905 v skupini B. Klinični znaki, stopnja umrljivosti in rane so bili pri cepljenih kokoših blagi, hude rane pa so bile vidne pri necepljenih in okuženih kokoših. Stopnja zaščite je bila v skupinah A in B 85- oziroma 80-odstotna, v skupinah C in D pa 10- oziroma 20-odstotna. Stopnje ponovne izolacije P. multocida po okužbi so bile 90 in 95 odstotkov pri kokoših, ki niso bile cepljene, medtem, ko so bile v skupinah, ki so bile okužene s P. multocida serotipa A:1 in A:3 15- in 25-odstotkov. Histopatološki pregled cepljenih in okuženih kokoši je pokazal popolno odsotnost ali prisotnost blagih mikroskopskih poškodb, medtem ko so imele necepljene okužene kokoši bolj obsežne histopatološke poškodbe. Pripravljena inaktivirana bakterija FC iz lokalnih egiptovskih prevladujočih serovarov P. multocide se je izkazala za učinkovito zaščito kokoši nesnic.Ključne besede: Pasteurella multocida; kokoši; imunizacija; zaščita; Egipt
