Objective: To compare the effect of epidural steroid injections (ESI) in patients with discogenic sciatica (Sci) versus patients with lumbar canal stenosis (LSS), not controlled by conservative treatment.

Materials and methods: In our study, 80 patients with Sci and 66 with LSS were included. A single ESI (10 mg dexamethasone in 3 cc 0.25% bupivacaine) was applied under fluoroscopic control: one level above the highest stenotic level, in the posterior epidural space, via interlaminar approach in LSS and at the prolapse level, in the anterior epidural space, via transforaminal route in Sci. Pain intensity was assessed by VAS at baseline and on days 1, 15 and 30 after intervention.

Results: The procedure was successful in 78 Sci and 63 LSS patients. Patients with Sci responded significantly better. At one month, pain reduction over 50% was achieved in 63% (52.3-73.7% at p = 0.95) of Sci but only in 35% (23.2-46.8%) of LSS (p = 0.03). Return to pre-intervention level happened in 47% (34.7-59.3%) of LSS versus 14% (6.3-21.7%) of Sci patients (p = 0.01). In 5 patients the procedure failed, without resulting morbidity.

Conclusion: ESI are more effective in patients with Sci than in single level LSS. In multiple level LSS, results are disappointing.

Primary hyperaldosteronism (PA) is the most common cause of secondary arterial hypertension and is frequently undiagnosed. It affects all ages but is more frequent between 20 and 60 years old. The clinical presentation is variable, and the diagnosis is based on screening and, in equivocal cases, confirmatory tests. A 19-year-old student presented with complaints of extreme fatigue, arterial hypertension, hypokalemia and metabolic alkalosis, raising a high index of suspicion for PA. Screening tests were performed and its expressiveness excluded the need of confirmatory tests. CT-scan showed a unilateral adrenal adenoma and the patient was submitted to laparoscopic adenectomy without complications. Prompt diagnosis and treatment are essential to avoid long term complications of PA.

Background: The aim of this study was comparison the effectiveness of sequential and standard quadruple therapy on eradication of H. pylori infection.

Methods: This clinical trial study was conducted on 160 patients with dyspepsia or gastroduodenal ulcer. Patients were randomly divided into two groups. Group A (standard regimen) received omeprazole, amoxicillin, clarithromycin and bismuth subcitrate for 2 weeks. Group B (sequential regimen) received omeprazole and amoxicillin in 5 days and omeprazole, tinidazole and levofloxacin in 5 days. After the end of treatment regimens, 20 mg omeprazole was administered twice daily for 3 weeks. H. pylori eradication was assessed 2 months after antibiotic treatment via fecal antigen.

Results: Frequency of H. pylori eradication in group A and B was observed in 55 (68.8%) and 63 patients (78.8%), respectively. No significant difference was seen between two groups, regarding H. pylori eradication (p = 0.15). The most common side effects in group A, B were bitterness of mouth (63.8%) and nausea (16.2%), respectively (p H. pylori infection, higher rate of H. pylori eradication was seen in group B than group A. Thus, sequential regimen was a more appropriate regimen with fewer complications.

74 year-old-man, former smoker, with chronic obstructive pulmonary disease GOLD grade 4, group D, with emphysema component, treated in a pulmonary rehabilitation program, on oxygen therapy and nocturnal bi-level positive airway pressure (BiPAP) ventilation. During the night he had a traumatic rib fracture (5-11th right ribs) but still he used BiPAP ventilation during the sleep. In the morning after he presented with a diffuse and massive emphysema in the face, thorax and abdominal regions. On physical examination, the patient presented with massive swelling and crepitus on palpation. A chest computed tomography (CT) scan confirmed a diffuse subcutaneous emphysema and revealed a mediastinal emphysema and bilateral small pneumothorax. A fast resolution of the emphysema was of paramount importance as the patient was severely agitated due to his inability to open both eyes, and the need to reintroduce BiPAP ventilation as soon as possible. It was placed a fenestrated subcutaneous catheter on left hemithorax and a subcutaneous ostomy on right hemithorax for comparative purpose. It was also performed a confluent centripetal massage towards drainage orifices, with immediate and substantial improvement of emphysema, especially in left hemithorax, and progressive ocular opening. Further emphysema absorption occurred during hospitalization.

Pseudoxanthoma elasticum (PXE) is a rare hereditary disorder occurring due to metabolic defect in the liver and manifesting predominantly in the skin, eyes and arteries. It shows characteristic yellowish papules on the skin around the nape of neck along with looseness of skin over flexural surfaces. PXE shows marked phenotypic heterogeneity. Complications related to arterial wall and retinal Bruchs' membrane calcification occur later in life; early diagnosis therefore helps keep patient on follow up for development of the same. In Indian patients, classic skin changes may be missed clinically making histopathology pivotal in diagnosis and patient management.

Background: The prophylactic administration of tranexamic acid has been shown to be appropriate for procedures with a high risk of perioperative bleeding in cardiac surgery and orthopaedics. In urology the ambiguous results have been reported. Our goal was to evaluate the effect of tranexamic acid administration in robotic-assisted radical prostatectomy (RARP). A pilot, prospective, double-blind, randomized study was conducted to evaluate this effect.

Methods: The study included 100 patients who received RARP in the period from April 2017 to January 2018. The patients were randomly assigned to study and control groups of 50 patients each.

Results: The median follow-up was 6 months. Lower haemoglobin level drop weighted for gram of operated prostate was observed in the study group when treating the dorsal vein complex (DVC) at the beginning of the procedure (p = 0.004 after 3 hours and p < 0.001 after 24 hours). There was no evidence of any serious side effect of tranexamic acid.

Conclusion: We demonstrated the safety of tranexamic acid at RARP. In addition, we showed that administration of tranexamic acid at the beginning of RARP significantly reduces the decrease in haemoglobin after the procedure when treating the DVC at the beginning of the procedure.

Background: A tremendous level of success has been achieved since the introduction of chloroquine and the combination of amodiaquine and artemisinin for the treatment of both complicated and uncomplicated malaria infections in sub-Saharan Africa. However, the recent discovery of drug resistant strains of Plasmodium falciparum (P.f.) and the ability of the parasite to ingest CYP2C8 into its digestive vacuole is of great public health concern. This study probes the occurrence of CYP2C8*2 allelic mutant amongst malaria patients in North-Central Nigeria.

Methods: Three hundred and eighty five (385) unrelated study participants were screened for current malaria episodes using routine microscopy and/or rapid diagnostic test strips (RDTs). Chelex extraction method was used for single nucleotide polymorphisms (SNPs) and identification of CYP2C8*2 (805A > T) variant respectively. Wild-type (A) and the defective allele (T) were differentiated with the use of Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP). The results obtained were further validated with Sanger sequencing of a few samples and thereafter, the genotype data were statistically processed. All alleles obtained were in Hardy Weinberg equilibrium.

Results: Out of the 385 participants (45.5% Male and 54.5% Female) genotyped for SNPs, 75 (19.5%) had the autosomal recessive mutant trait. Occurrence of mutant traits was gender and ethnic independent (p > 0.05). Yoruba ethnic group recorded a reduction in proportion of genotypic defective CYP2C8*2 allele (T) (1 in every 8 persons) with a carrier percentage of 13.3% compared with Hausa (26.62%); Igbo (25.37%) and other minority ethnic groups (17.6%).

Conclusions: A remarkable inter-ethnic differences in autosomal recessive CYP2C8*2 allele was observed. By implication, there is a gradual incursion of genetic drift for poor CQ and AQ-Artemisinin metabolizers among the inhabitants.

The clinical presentation of iron deficiency can be very heterogeneous, including various oral and other mucosal problems. Here, in this case, we report the patient with burning mouth and dysphagia symptoms where iron deficiency was found to be the underlying cause after several months of investigations. This clinical syndrome is called Plummer-Vinson syndrome. It is sporadic with an incidence less than 0.1% of patients suffering from iron deficiency anemia.

Aim: To evaluate the effects of orally administered gadolinium orthovanadate GdVO4:Eu3+ nanoparticles (VNPs) on the course of chronic carrageenan-induced intestinal inflammation.

Methods: Samples of small intestinal tissue were collected from four groups of rats (intact, after administration of VNPs, with carrageenaninduced intestinal inflammation, with carrageenan-induced intestinal inflammation orally exposed to VNPs) to assess the intestinal morphology and HSP90α expression. Levels of seromucoid, C-reactive protein, TNF-α, IL-1β and IL-10 were determined in blood serum.

Results: Oral exposure to VNPs was associated with neither elevation of inflammation markers in blood serum nor HSP90α overexpression in the small intestine, i.e. no toxic effects of VNPs were observed. Carrageenan-induced intestinal inflammation was accompanied by higher levels of TNF-α and IL-1β, as well as HSP90α upregulation in the intestinal mucosa, compared with controls. Administration of VNPs to rats with enteritis did not lead to statistically significant changes in concentrations of circulating pro-inflammatory cytokines with the trend towards their increase.

Conclusion: No adverse effects were observed in rats orally exposed to VNPs at a dose of 20 μg/kg during two weeks. Using the experimental model of carrageenan-induced enteritis, it was demonstrated that VNPs at the dose used in our study did not affect the course of intestinal inflammation.

Introduction: Ionised hypocalcemia (S-Ca2+) has been repeatedly observed in neonates with sepsis. Our aim was to evaluate total calcemia (S-Ca) and its relationship to laboratory markers of infection.

Methods: We retrospectively evaluated total calcemia (S-Ca) and its relationship to laboratory markers of sepsis/infection (serum levels of C-reactive protein - S-CRP and procalcitonin - S-PCT) in 29 full-term neonates with early-onset neonatal infection hospitalized at our neonatology ward between 2012 and 2016. The control group consisted of 705 neonates without infection.

Results: In neonates with early-onset infection , the S-Ca on day 1, 2 and 3 was significantly lower (p < 0.0001; p < 0.0001; p = 0.05 versus controls) same as the pooled S-Ca (p < 0.0001 versus controls). There was a weak negative correlation between pooled S-Ca and S-PCT, or pooled S-Ca and S-CRP (r = -0.22, p = 0.06; r = -0.19, p = 0.09).

Conclusion: S-Ca was decreased in neonates with early-onset infection and did show a slight tendency to inverse correlation with S-CRP and S-PCT. Pediatricians must be aware of the fact that a drop in total S-Ca should alert their attention to the risk of neonatal infection, and, likewise, that the children with neonatal infection are at a higher risk of hypocalcemia with all its consequences.
