Background and Aim: Tandem Spinal Stenosis (TSS) can be defined as simultaneous stenosis of two distinct spinal (cervical, thoracic and lumbar) areas. Characterized by an association of the spinal, radicular and medullary signs of the limbs, the planning of his surgery remains controversial. We reported the one that was set up on the cases observed at the Brazzaville Academic Hospital.  Methods and Materials/Patients: A retrospective study of 16 patients operated for TSS, from June 2009 to May 2019, was conducted. We analyzed the demographic, clinical, paraclinical, therapeutic and evolutionary data of these patients. Results: For ten years, a total of 16 patients (9 men and 7 women) with SST have been received. The average age was 57 years (ranged 41-72 years). The signs evolved for 17.6 months (13 and 30 months). These were lombo-sciatalgias in 15 cases, signs of medullary compression: cervical in 14 cases and thoracic in 2 cases. Medical imaging had objective 13 cervico-lumbar associations, two thoraco-lumbar associations and one cervico-thoracic. The surgery was performed in one stage in two cases and two stages in 14 cases. These were laminectomies for lumbar and thoracic disorders, discectomy or somatotomy in the cervical segment. The order of surgical management was cervico-thoraco-lumbar (cranio- caudal order). Signs improved in 13 patients and stabilized in 3 patients. Conclusion: TSS is not uncommon. It should be researched in a patient with bifocal spinal and radiculo-medullary signs. Their early surgical treatment, in one or two stages, yields satisfactory results.

The purpose of this review is to present an up-to-date look at the features of diagnosis and treatment of tandem spinal stenosis. Tandem spinal stenosis is a degenerative narrowing of the spinal canal of two or more parts of the spine column. Diagnosis of the one-level degenerative spinal stenosis is commonly quite easy in the practice of a spinal surgeons, while the diagnosis of tandem spinal stenosis is often difficult. The clinical presentation of tandem spinal stenosis presents a constellation of different symptoms and often cause late diagnosis. Data on the prevalence of tandem spinal stenosis are very variable, and the etiology cannot be fully studied. Thereby, comprehensive assessments of the symptoms and imaging provide assistance with the accurate and timely diagnosis. The choice of surgical method should consider possibility of staged decompression of each stenotic levels with priority for proximal parts of spine column.

Study on co-fermentation of cow dung (CD) and giant dirt (GD - Pistia stratiotes L.) in semi-continuous anaerobic digester aims to test biogas quantity and quality by time. Three mixing rates counted based on ODM of each material were chosen: 100 %CD, 50 %CD + 50 %GD, and 100 %GD. The experiments were set up in laboratory conditions with two types of digesters: one-stage digesters and two-stage digesters (triplicate for each treatment). After 80 days, the biogas produced from the one-stage digesters was not significantly different to the two-stage digesters with similar input material. The highest production of biogas came from digesters of 100 %GD - 235.8 L for the one-stage and 240.3 L for the two-stages. The medium production came from digesters of 50 %CD + 50 %GD - 127.8 L for the one-stage and 118.4 L for the two-stages. After one month, the percentage of CH4 was high enough for burning and almost giant dirt was digested that limited of a blockage inside the digesters. The results showed that co-fermentation of GD and CD is an alternative for livestock raising households to produce biogas for energy purpose.

Set Up

Spinal arteriovenous malformations are relatively rare, being one tenth as common as cerebral AVMs and one tenth as common as primary spinal neoplasms. The aim of this retrospective study was to see distribution of this disease in spinal cord and analyse outcome of surgical treatment in our set-up. 5 patients with neurologic deficit due to spinal AVMs were operated upon from March 2000 to Feb 2005. Age ranged from 25-45 years with mean of 35 years. There were 2 females and 3 males with sex ratio of 1:1.5 respectively. Spinal AVMs were categorized as one of 4 types based on pattern of arterial and venous supply. We found that 60% (3 cases) in our series were intradural AVMs while 40% (2 cases) were dural type. We conclude that glomus variety of intradural AVMs was the commonest. The commonest presentation was acute spinal dysfunction and paraparesis. Selective spinal angiography can be negative in spinal AVMs, (20%) in our series, in which CT angiography provided clue to the feeding vessels.

Abstract Background Students’ perception of the educational setting is an important source for improving and applying changes to the educational environment. In this study, we reassessed undergraduate students’ perception of the educational environment at two colleges of RUMS-Iran in the academic years of 2011 and 2016. Methods In the present prospective study, the DREEM inventory consisted of seven courses for undergraduate paramedical and nursing-midwifery students (n = 982). After the first stage, educational seminars and workshops were set up for academic members and faculty staff on deficiencies and the ideal climate for optimizing the educational environment. The results of students’ responses in 2011 were compared with those assessed in 2016. For the data analysis, the independent t-test and the one-way ANOVA were utilized. Results In the academic year of 2010–2011, the DREEM inventory scored 115.33/200 (57.66%); it also scored 123.47/200 (60.7%) in the academic year of 2015–2016 (p ≤ 0.01). There was an interesting feeling about the first-year education, and female students felt a more positively perceived learning environment during all courses than male students at both stages of the study. There were significant positive differences (2 to 7%) in all domains of the components of DREEM in all courses between the academic year of 2010–2011 and the academic year of 2015–2016, showing that the DREEM score had changed and increased (p < 0.05), in the latter case. Conclusions Positive differences were observed in DREEM scores between the two stages of the study. DREEM helped reduce the areas of deficiencies in students’ perception of many aspects of the educational environment. It also helped identify problematic areas in the improvement. In addition, DREEM could be used to optimize and make modifications to the educational environment.

Introduction: Perianal hidradenitis suppurativa is a chronic recurrent inflammatory, suppurative, and fistulising disease of apocrine glands, adjacent anal canal and soft tissues. Perianal area is the second most common affected area after axilla. There are three grades of the disease. Hidradenitis suppurativa represents a chronic, recurrent, deep-seated folliculitis resulting in abscesses, followed by the formation of sinus tracts and subsequent scarring. Perianal hidradenitis suppurativa is the last and the most serious grade of the disease and a specific access is needed for patient preparation and surgical treatment alone. The currently preferred method of treatment for patients with extensive perianal hidradentitis is excision and closure with combination of skin flaps, primary suture and skin graft in one or two stages. Case reports: There are three case reports of perianal hidradenitis suppurativa in this article. The local and overall initial treatment of patients followed by a radical excision and closure with a rotation skin flaps and skin grafts is described. The final results were satisfactory, with no recurrence or serious complication.
