Abstract
Ambriss, Serdaleh and Labneh El Darff are traditional Lebanese products made from fermented goat's milk. A questionnaire completed by 50 producers of these products showed that they are prepared by periodic percolation either by milk or by Laban in amphora or goat skins during the lactation season. Production is carried out on a small scale and in a limited number of production units, often by elderly people, resulting in a real risk of disappearance of these products and loss of the corresponding microbial resources. In this study, 34 samples from 18 producers were characterized by culture-dependent and -independent analyses. The results obtained from these two methods were radically different, the latter revealing in Ambriss and Serdaleh the co-dominance of Lactobacillus kefiranofaciens, a fastidious-growing species, and Lactococcus lactis in a viable but not culturable state. Overall, their composition is reminiscent of kefir grains. Phylogenomic and functional analyses of the genomes of the key species Lb. kefiranofaciens have revealed differences from those found in kefir, particularly in their polysaccharide genes, which may explain the absence of grains. However, Labneh El Darff displayed a dominance of Lactobacillus delbrueckii, probably due to the addition of Laban. In addition, the study identified several zoonotic pathogens, including Streptococcus parasuis, which dominated in one sample. Metagenome-Assembled Genome (MAG) analysis indicated that this pathogen acquired lactose utilization genes through horizontal gene transfer. The contamination of the herd with Mycoplasmopsis agalactiae in the Chouf region was also revealed by MAG analysis of the Serdaleh samples. Antibiotic resistance genes were detected in most of the samples, particularly in the Serdaleh ones, where the dominant L. lactis strains possessed a plasmid with a multi-resistance island. Finally, this study paves the way for further analyses to shed light on the resilience of these ecosystems established in amphora or in goatskins and to improve hygiene practices for milk production.

Abstract
The importance of protective eyewear during activities which involve high velocity projectiles is often emphasized to patients, however the material and design of such eyewear is also important. We present the case of a boy who sustained ocular injury from a plastic airsoft bullet while wearing a protective mask issued by the manufacturer. The patient was found to have decreased vision, a corneal abrasion and hyphema. The patient fully recovered with topical prednisolone, cyclopentolate, and moxifloxacin. It is important to advocate for using polycarbonate protective eye wear for our patients who are engaging in activities which involve high velocity projectiles.

Abstract
Objectives The aim of this study was to evaluate the clinical validity of early Sjögren's syndrome (SS) autoantibodies (eSjA), which were originally marketed for early diagnosis of SS, for juvenile SS (JSS) in a recently identified pediatric cohort. Methods A total of 105 symptomatic subjects with eSjA results available were evaluated at the Center for Orphaned Autoimmune Disorders at the University of Florida and enrolled for this study. JSS diagnosis was based on the 2016 ACR/EULAR SS criteria. Demographic/clinical/laboratory parameters were compared between JSS (n = 27) and non-JSS (n = 78) for % positivity, sensitivity, and specificity of eSjA (SP1, anti-salivary protein; CA6, anti-carbonic anhydrase VI; PSP, anti-parotid secretory protein) and classic SS-autoantibodies (cSjA; ANA, SSA/SSB, RF, and others) either alone or in combination. Associations between eSjA and diagnostic/glandular parameters were also determined by Fisher's exact test. Results Compared to non-JSS, JSS patients exhibited sicca symptoms demonstrating reduced unstimulated salivary flow rate (USFR) and abnormal glandular features revealed by salivary gland ultrasound (SGUS). Among cSjA, ANA demonstrated the highest sensitivity of 69.2%, while SSA, SSB, and RF showed around 95% specificities for JSS diagnosis. The % positive-SSA was notably higher in JSS than non-JSS (56% vs. 5%). Of eSjA, anti-CA6 IgG was the most prevalent without differentiating JSS (37%) from non-JSS (32%). Sensitivity and specificity of eSjA were 55.6 and 26.9%, respectively. Autoantibodies with potentially applicable specificity/sensitivity for JSS were seen only in cSjA without a single eSjA included. There were no associations detected between eSjA and focus score (FS), USFR, SSA, SGUS, and parotitis/glandular swelling analyzed in the entire cohort, JSS, and non-JSS. However, a negative association between anti-PSP and parotitis/glandular swelling was found in a small group of positive-SSA (n = 19, p = 0.02) whereas no such association was found between anti-PSP-positive compared to anti-PSP-negative. JSS and non-JSS groups differed in FS, USFR, and EULAR SS Patient Reported Index Dryness/Mean in CA6/PSP/ANA, SP1, and SSA-positive groups, respectively. Additionally, a higher FS was found in RF-positive than RF-negative individuals. Conclusions eSjA underperformed cSjS in differentiating JSS from non-JSS. The discovery of clinical impact of eSjA on early diagnosis of JSS necessitates a longitudinal study.

Abstract
INTRODUCTION Cervical cancer is the twelfth most frequent cancer in women in France. Glassy cell carcinoma is a rare histological entity, rapidly aggressive, associated with a poor prognosis. CASE REPORT A 30-year-old woman was admitted in an internal medicine department for polyarthralgia with high grade fever, evolving for 3 weeks. There was an inflammatory syndrome. The 18-FDG-PET-scan showed inflammatory lymph nodes as well as disseminated osteolytic lesions, and a primitive pelvic tumor. A 3cm tumor of the cervix was found during the gynaecologic examination. Histological analysis elicited a high-index mitotic carcinoma, glassy cell carcinoma type. Despite chemotherapy, the outcome was poor, with early death occurring after three months of follow-up. CONCLUSION The glassy cell carcinoma of the cervix should be considered as an aetiology of bone metastases in young female patients.

Abstract
Patients with the primary symptom of a red eye are commonly seen in pediatric primary care clinics. The differential diagnoses of a red eye are broad, but with a succinct history and physical examination, the diagnosis can be readily identified in many patients. Identifying conditions that threaten vision and understanding the urgency of referral to an ophthalmologist is paramount. Some systemic diseases such as leukemia, sarcoidosis, and juvenile idiopathic arthritis can present with the chief symptom of a red eye. Finally, trauma, ranging from mild to severe, often precipitates an office visit with a red eye, and thus understanding the signs that raise concern for a ruptured globe is essential. In the primary care setting, with a focused history, a few simple examination techniques, and an appreciation of the differential diagnosis, one can feel confident in managing patients with acute red eyes.

Abstract
Introduction:Several studies have already reported increased prevalence of metabolic and cardiovascular risk factors in patients on antipsychotics. This observational aimed to assess the prevalence of metabolic syndrome (MetS) in differently treated patients with schizophrenia.Methods:Patients with schizophrenia (age >=18 years) from 162 psychiatric practices throughout Germany were enrolled if they were either treatment-naive and initiated on antipsychotic therapy, or had received previous antipsychotic treatment and were switched to a new medication. Baseline physical and laboratory parameters were evaluated to assess the prevalence of MetS (American Heart Association's definition). Clopper-Pearson 95%CIs were calculated. Patients were assigned to evaluation cohorts by previous treatment: olanzapine (Olz, N=62), risperidone (Risp, N=67), quetiapine (Quet, N=49), other atypical monotherapy (Atyp, N=103), typical therapy (Typ, N=90), atypical combination (Comb, N=109), treatment-naive (TN, N=162).Results:The sample included 642 patients, mean age 45.2 ±13.3 years, 325 (50.6%) women. Characteristics for the TN-cohort were: mean BMI 25.3 ±4.5, mean blood triglycerides 157.3 ±122.4 mg/DL, rates of concomitant diseases (28.4%), and prevalence of MetS (24.7%, CI18.3;32.1). in comparison, previously treated patients had a mean BMI: 27.0 ±4.9 (Quet) to 29.3 ±5.4 (Comb), mean triglycerides: 182.4 ±116.9mg/DL (Risp) to 232.3 ±164.3mg/DL (Comb), concomitant diseases: 29.9% (Risp) to 41.7% (Comb), MetS: 42.4% (Risp, CI30.3-55.2) to 57.0% (Comb, CI47.1-66.5).Conclusion:TN-patients (see above) had a significantly lower prevalence of MetS than the overall sample (42.8 CI 38.9;46.7). Comb-patients showed the highest prevalence of MetS. Typ-patients had a similar prevalence of MetS (43.3, CI32.9;54.2) than patients treated with atypical antipsychotics.

Abstract
The resistance to freezing and frozen storage of Streptococcus thermophilus was related to the fatty acid composition of the cell membrane. The effects of four experimental factors were investigated on the fatty acid concentrations and on the recovery of acidification activity of S. thermophilus stored at -20 degrees C by using a complete experimental design: incorporating oleic acid in the culture medium, fermentation pH, addition of glycerol as cryoprotective agent and duration of storage. The acidification activity decreased during the freezing and the frozen storage of S. thermophilus. The storage time slightly enhanced the unsaturated fatty acid concentrations. The addition of glycerol did not modify the fatty acid composition but increased the resistance to frozen storage. The addition of oleic acid and the decrease of the fermentation pH enhanced the ratio unsaturated:saturated fatty acids and improved the recovery of the acidification activity. These results indicate that the resistance to frozen storage was closely related to the membrane fatty acid composition. We interpreted this as an adaptation of S. thermophilus to the addition of oleic acid and the unfavorable growth conditions that corresponded to a low fermentation pH.

Abstract
An item analysis of the Hooper Visual Organization Test (VOT) was performed using the test protocols of 320 German-speaking neurological patients with a mean age of 51.3 years. All patients presented some form of cerebral pathology. The sample yielded a mean test score of 18.8 (SD = 6.2). Estimates of internal consistency of the total scale yielded acceptable results (>.88). Although the VOT was judged to be a useful instrument for assessing visuoperceptual and visuospatial-organizational dysfunction, item characteristics of the test are not satisfactory. In particular, the item ranking does not correspond to the order of difficulty. Moreover, in their current form, scoring rules of a number of items seem to be arbitrary and not founded on empirical data. A revision of the VOT is proposed to improve its psychometric properties.

Abstract
A 47-year-old native American (TOU) was admitted to hospital for hip surgery. His serum agglutinated all red blood cells (RBCs) tested except Ko and DTT-treated RBCs and was weakly reactive with RBCs known to have a weak expression of Kell antigens, namely Kmod, McLeod, Kp(a+b-) (KEL:3,-4) and K:-13 (KEL:-13) phenotypes. RBCs from three siblings, a son and a daughter were incompatible with TOU's antibody. TOU's RBCs had the common Kell phenotype: K-k+Kp(a-b+c-)Ku+Js(a-b+)Ul(a-)K:11,-17K:14,-24K:12,13,18,19, 22,-23(KEL:-1,2,-3,4,5,-6,7,-10,11,12,13,14,-17,18,19,-21,22,-23,-24). Since TOU's RBCs were not agglutinated by an unidentified Kell-related antibody (IAN), tests were performed to show that TOU and IAN were mutually compatible. IAN is a Latino female hospitalised for a hysterectomy. The TOU antigen was shown to be located on the Kell glycoprotein by a monoclonal antibody immobilisation of erythrocyte antigen (MAIEA) assay. The unique pattern of reactivity obtained with TOU and IAN antibodies using this assay indicated the TOU epitope to be in an area remote from other Kell antigens, namely K, k, Kpa, Kpb, Kpc, Ku, Jsa, Jsb, U1a, K11, K12, K13, K14, Wka, K18, K19, K22 and K24 (KEL1, KEL2, KEL3, KEL4, KEL5, KEL6, KEL7, KEL11, KEL12, KEL13, KEL14, KEL17, KEL18, KEL4, KEL5, KEL6, KEL7, KEL11, KEL12, KEL13, KEL14, KEL17, KEL18, KEL19, KEL21, KEL22 and KEL24) but close to the low-incidence antigen K23 (KEL23).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Although culture of Trichomonas vaginalis is more sensitive than wet mounts in the diagnosis of trichomoniasis, the lack of convenience of culture prevents it from being widely used. To improve the acceptability of diagnosis by culture, a plastic envelope method (PEM) was devised. PEM permits both immediate examination and culture in one self-contained system. The medium consists of dry ingredients that are reconstituted with water before use. The effectiveness of immediate examinations by PEM was compared with that of wet mounts, and the effectiveness of culture by PEM was compared with that of culture in Trichomonas Medium No. 2 (Oxoid). Of 710 vaginal secretion specimens from symptomatic and asymptomatic women that were tested by the four methods, 62 (9%) were positive for T. vaginalis. The sensitivity was 66% by wet mount, 66% by immediate examination by PEM, 89% by cultures in Oxoid medium, and 97% by culture by PEM. The two culture methods had equivalent sensitivities but were significantly (P less than 0.0001) more sensitive than the two immediate methods. The combined immediate examination by PEM plus culture was more convenient to use than wet mounts plus culture in Oxoid medium. The long shelf-life of PEM's dry medium and its anticipated low cost are additional advantages.

Six healthy pony foals, from 2 to 11 days of age, were given a single IM injection of amikacin sulfate (250 mg/ml) at a dosage rate of 7 mg/kg of body weight. Serum amikacin concentrations were measured serially over a 24-hour period. The mean peak serum concentration was 14.7 micrograms/ml at 0.5 hour. The elimination rate constant for amikacin was 0.24/hour, the elimination half-life was 3.0 hours, and the apparent volume of distribution was 0.58 L/kg.

Abstract
Six mares were given 5 IM injections (at 12-hour intervals between doses) of amikacin sulfate at a dosage of 7 mg/kg of body weight. Serum amikacin concentrations were measured serially throughout the study; synovial, peritoneal, endometrial, and urine concentrations were determined after the last injection. Amikacin concentrations of the CSF were measured serially in 3 of the 6 mares; 1 of the 3 mares had septic meningitis. Mean serum amikacin concentrations peaked at 1 to 2 hours after IM injection. The highest mean serum concentration was 19.2 micrograms/ml (1.5 hours after the 5th injection). The highest mean synovial concentration was 10.8 micrograms/ml at 2 hours after the 5th injection; the highest mean peritoneal concentration was 16.2 micrograms/ml at 3 hours after the 5th injection. The mean endometrial amikacin concentration was 2.5 micrograms/g (1.5 hours after the 5th injection). Amikacin reached a CSF concentration of 0.97 micrograms/ml in the mare with meningitis, but amikacin was not detected in CSF of healthy mares. Urine concentrations reached 1,458 micrograms/ml. Pharmacokinetic values were estimated after the 1st injection (elimination rate constant = 0.31/hour; half-life = 2.3 hours; apparent volume of distribution = 0.26 L/kg), and after the 5th injection (elimination rate constant = 0.28/hour; half-life = 2.6 hours; apparent volume of distribution = 0.30 L/kg); significant differences were not observed.

Abstract
Five foals from two to three days old were given a single oral dose of ampicillin trihydrate (20 mg/kg bodyweight [bwt]). Serum ampicillin concentrations were measured serially over a 24 h period. The study was repeated in the same foals at 16 to 21 days old. The mean peak serum ampicillin concentration at two to three days old was 5.0 micrograms/ml at 1 h after treatment; the mean peak serum concentration at 16 to 21 days old was 2.7 micrograms/ml at 2 h. The concentrations steadily declined and ampicillin was not detected in the serum from any of the foals by 24 h. Serum clearance averaged 17.7 ml/min/kg at two to three days and 35.8 ml/min/kg at 16 to 21 days.
