Study Design: This was a retrospective study. Purpose: The aim was to compare the clinical, laboratory, radiological, and evolutionary features of tuberculous spondylodiscitis (TS) and brucellar spondylodiscitis (BS). Overview of Literature: Clinical presentation of spondylodiscitis varies according to the underlying etiology, among which brucellosis and tuberculosis represent the primary cause, in endemic countries. Only a few studies have compared the characteristics between TS and BS. Methods: A retrospective study was conducted using the data of all patients hospitalized for TS and BS in the infectious diseases department between 1991 and 2018. Results: Among a total of 117 patients, 73 had TS (62.4%) and 44 had BS (37.6%). Females were significantly more affected with TS than males (56.2% vs. 22.7%, p <0.001). Fever (72.7% vs. 45.2%, p =0.004) and sweating (72.7% vs. 47.9%, p =0.009) were significantly more frequent among patients with BS. The median erythrocyte sedimentation rate was significantly higher in the TS group (median, 70 mm/hr; interquartile range [IQR], 45–103 mm/hr) than in the BS group (median, 50 mm/hr; IQR, 16–75 mm/hr) (p =0.003). Thoracic involvement was significantly more frequent in the TS group (53.4% vs. 34.1%, p =0.04), whereas lumbar involvement was significantly more frequent in the BS group (72.7% vs. 49.3%, p =0.01). Initial imaging findings revealed significantly higher frequencies of posterior vertebral arch involvement, vertebral compaction, and spinal cord compression in the TS group. Percutaneous abscess drainage (20.5% vs. 2.3%, p =0.005) and surgical treatment (17.8% vs. 2.3%, p =0.01) were more frequently indicated in the TS group, with a significant difference. Conclusions: A combination of clinical, laboratory, and radiological features can be used to distinguish between TS and BS while these patients await diagnosis confirmation.

Pectin is a polysaccharide attached to carbohydrates. These are substances exclusively of plant origin. The aim of the present study is to evaluate the laxative effects of orange peel pectin extract (OPPE) against constipation induced by loperamide (LOP) in rats. Rats were equally divided into six groups and treated daily 1 week as follows: Control, LOP (3 mg/kg, body weight [b.w.], Per Os [p.o.]), LOP+yohimbine (2 mg/kg, b.w., i.p.), and LOP+OPPE (6.25, 12.5, and 25 mg/kg, b.w., p.o.). At the end of the experiment, the effects of OPPE were assessed by fecal parameters (numbers, weight, and water content), gastrointestinal transit, gastric emptying, serum metabolic parameter changes, intestinal and colon mucosa oxidative stress, and the histological examination. The defecation test showed that administration of LOP (3 mg/kg, b.w., p.o.) leads to the production of remarkable constipation. Indeed, the number and water content of stools decreased (25.50 [n/24 h] and 29.86%) significantly (P < .05). Acute pretreatment with OPPE significantly and dose dependently accelerated the stool moistening and allowed an increase of stool weight (2.85, 3.61, 3.93 [g/24 h/rat]) as well as the frequency of defecation (47.36, 54.54, and 56.26 [n/24 h]). OPPE also significantly (P < .05) and dose dependently increased the intestinal motility (70.78%, 73.33%, and 75.01%) and gastric emptying. LOP-induced reduction (P < .05) of intestinal secretion was accompanied by a colonic and small bowel oxidative stress status and histological changes, which was attenuated by OPPE treatment. The findings of this study indicate that OPPE possesses an important role in the gastrointestinal motility regulation, and thus lend pharmacological credence to the suggested use of the natural pectin for the treatment, management, and/or control of constipation.

Effects of Garlic Fractions Consumption on Male Reproductive Functions

Many researchers have focused on the preventive and curative effects of garlic (Allium sativum), particularly on cardiovascular diseases and cancer. However, its impacts on the male reproductive system have not been clearly defined. In this study, the effect of chronic consumption of two garlic fractions was tested: one soluble in water (aqueous solution obtained by grinding and centrifugation) and the other one precipitated by ethanol (alcoholic precipitate obtained by precipitation of the aqueous solution), on different variables of male rats’ reproductive functions. These two fractions were targeted to try to identify the nature of the active garlic compounds responsible for the different modifications observed on testicular parameters. The observation of seminiferous tubules of rats treated with garlic fractions showed an increased number of tubules deprived of spermatozoa. In addition, garlic fractions induced apoptosis of testicular germ cells (TdTmediated dUTP-X nick-end labeling [TUNEL] approach) and a decrease of serum testosterone levels and seminiferous tubule DNA concentrations. In summary, our histological and molecular results suggest that one or several substances, soluble in water and precipitated by alcohol, impaired spermatogenesis.
