Surgical Science (SS) , 2019, DOI: 10.4236/ss.2019.101006
Abstract: Introduction: The word “Teratoma” derives from the Greek word “teratos” including the meaning show. Teratoid tumors derived from the transformation of multipotent germ cells. They are composed of ectodermal, endodermic and mesodermal tissues in variable proportions; hence the term “embryonic tumor”. Objectives: We are reporting the case of a mature teratoma discovered in a young child whose delivery was vaginally performed. Through this case we put in diagnostic and therapeutic highlight and we made a literature review. Case report: Patient 17 months admitted for the anterior compartment mass associated with inspiratory dyspnea. No anomaly/abnormality was detected during the follow-up of the pregnancy. The Patient with dyspnea grade 2 was admitted according to Chevaleir-Jackson classification. No abnormalities of stature ponderal developments were noted. Surgery of excision was our therapeutic alternative. Through the pathological examination a mature teratoma was found. Conclusion: Teratoma is a rare condition. Proper management of mature teratoma helps to prevent recurrence.

Surgical Science (SS) , 2019, DOI: 10.4236/ss.2019.101002
Abstract: Objectives: We report two types of anatomical variations of the recurrent laryngeal nerve in two patients. Through these two patients we wanted to highlight our surgical approach of the recurrent nerve in an unusual position and to describe the surgical implication of these almost rare variations. Case report: patient aged 28 and 58 admitted for goiter. They underwent a right lobisthmectomy. Both recurrences were approached retrograde. The anatomical variations of the nerve concerned the non-recurrent laryngeal nerve in the first patient. In the second patient there were three anatomical variations, namely an extra laryngeal bifurcation of the nerve, a pre-vascular position of the nerve and a branch connecting the vagus nerve and the recurrent nerve. No recurrence nerve injury was noted. Conclusion: The anatomical variations of the nerve are numerous. A careful dissection is a guarantee of a good prognosis.

Surgical Science (SS) , 2016, DOI: 10.4236/ss.2016.71003
Abstract: Objective: This study aims to analyze clinical, paraclinical and therapeutic aspects of sinusitis complications in the Otorhinolaryngology department at the teaching hospital of Gabriel Toure in Bamako. Materials and methods: This descriptive and longitudinal study was conducted on 12 months from March 2012 to February 2013 in 9 cases of sinusitis complications in the department of Otorhinolaryngology at the University Hospital Gabriel Toure in Bamako. Results: The average age of patients was 22.7 years; a median of 19 years within 6 men and 3 women with almost 12.9 days of care seeking duration. The factors of risky were the use of nonsteroid anti-inflammatory drugs NSAID (4 cases), maxillofacial trauma (1 case) and HIV (1 case). Facial pain was the major symptom, such as frontal oedema, rhinorrhea with pus shedding and nasal obstruction. Computer tomography was used for complications specification. Frontal sinusitis was the most encountered with subperiosteal abscess (44.4%). Streptococcus pneumoniae was identified in 3 cases. Medical treatment associated to surgery was conducted on 7 patients. Two cases of death have been registered. Conclusion: The complicated sinusitis is an emergency and dangerous disease requiring specific care by a multidisciplinary staff. Much of complications are commonly encountered despite the antibiotic era.

International Journal of Otolaryngology and Head & Neck Surgery (IJOHNS) , 2019, DOI: 10.4236/ijohns.2019.81001
Abstract: Introduction: Cervical cystic lymphangiomas are rare benign dysembryoplastic tumors of lymphatic origin. Its severity in the child is due on one hand to their fast evolution and the compression of the way aerodigestive and on the other hand, by the classical difficulty of their excision. The purpose of this work was to report a case of giant cervical cystic lymphangioma in a child to discuss the difficulties associated with its management in our context. Observation: This was a 3-year-old female child who was admitted to the ENT department of CHU “Luxembourg” for right lateral cervical swelling. The clinical examination had noted a large anterior-latero cervical swelling of soft, renitent, painless palpation, movable in relation to the superficial and deep plane, measuring about 20 cm × 17 cm, the skin was healthy. It wasn’t particularity to the rest of the physical examination. The diagnosis of giant cervical cystic lymphangioma was discussed. Thorough excision of the swelling by right lateral cervicotomy was performed. Anatomopathological examination of the operative specimen confirmed the diagnosis. The postoperative course was simple and the evolution was favorable. Conclusion: Cervical cystic lymphangiomas are rare. Their management involves surgery, with short and long-term post-operative outcomes are often excellent.

International Journal of Otolaryngology and Head & Neck Surgery (IJOHNS) , 2019, DOI: 10.4236/ijohns.2019.81007
Abstract: Aim: Our goal was to determine the histological profile of ENT lesions. Method: We carried out a retrospective and descriptive study in the ENT department and Cervico-Facial Surgery at the university hospital center Gabriel Touré (MALI) from 1995 to 2014. It made it possible to collect 450 cases. Result: We found a male predominance; 51.11% or a sex ratio of 1.04. The mean age of patients was 38.04 years with a standard deviation of 19.49 years and extremes of 3 months and 91 years. Benign tumors were the most frequent (154 cases or 34.22%) including 75 cases of adenomas and 43 cases of papillomas. Cancers accounted for 48.11% (or 153 cases) of all tumors and 34% of lesions. Carcinomas accounted for 81.04%, malignant lymphomas 13.72% and sarcomas 5.22% of cases. Among the 140 cases (31.11%) of inflammatory pseudotumors, we found 12 cases of tuberculosis and 15 cases of rhinoscleroma. Three (3) cases of dysplasia were observed. Conclusion: Interest should be focused on histology in order to initiate appropriate therapy.

Abstract: Aims: To describe the diagnostic aspects, surgical indications and post-operative complications of thyroidectomies performed in our department. Materials and method: A descriptive retrospective study that took place in the ENT Department and Cervicofacial Surgery of Gabriel TOURE University Hospital of Bamako. We did a comprehensive sampling of all goiter cases from January 2013 to December 2018. Were included in the study, the records of patients of all ages and genders, admitted into the ward and scheduled for thyroidectomy (partial or total). The exclusion criteria were incomplete hospitalization records. There were a total of 139 files were retained. Results: In 60 months, 139 cases were collected out of 1720 patients hospitalized for surgery, representing a hospital prevalence of 8.08%. The average age was 46.89 years. (123 women and 16 men). The socio-professional categories were dominated by housewives (68.34%). The reported functional signs were tachycardia, asthenia and other signs of dysthyroidism in 59% as well as signs of compression in 24.46%. In 72 cases or 51.80%, the patients consulted between 2 and 10 years of disease progression. Twenty patients or 14.39% had a history of familial goiter and 2 patients had a history of thyroid surgery. On physical examination the swelling was antero-cervical in 56.83% of cases. In 96 cases or 69.06% the glandular diameter was between 5 and 9 cm. In 2 cases or 1.43% we noted cervical adenopathy in the jugulo-carotid chain. Ultrasound, TSHus and fT4 were performed first-line and systematically in all our patients. Ultrasound objectified an appearance of multinodular goiter in 106 cases or 76.26%. In 60.43% of cases the patients were TI classes RADS 3, they were TI RADS 4A in 16 cases or 11.51%. CT scans were performed in 3 patients or 2.15% to specify the loco-regional extension, to look for possible lymph node invasion, and to compress or dipping the goiter. Surgical indication was placed in front of a multinodular goiter (GMN) in 106 cases or 76.26%, a single goiter in 11 cases or 7.9%, a single nodule greater than 3 cm in 17 cases or 12.23%, Basedow disease in 4 cases or 2.88% and a recurrence in one case 0.72%. We performed a lobo-isthmectomy in 56.11%, a total thyroidectomy in 20.14% of cases, subtotal in 20.86% of cases and total thyroidectomy with mediation-recurrent lymph node curage and bilateral jugulo-carotidien in 4 cases or 2.87%. Recurrent nerves were systematically searched and seen in all cases. Replacement therapy was indicated in all
Numerical Simulation of Unsteady Friction in Transient Two-Phase Flow with Godunov Method  [PDF]
Samba Bousso, Musandji Fuamba
Journal of Water Resource and Protection (JWARP) , 2013, DOI: 10.4236/jwarp.2013.511110

Most numerical transient flow models that consider dynamic friction employ a finite differences approach or the method of characteristics. These models assume a single fluid (water only) with constant density and pressure wave velocity. But when transient flow modeling attempts to integrate the presence of air, which produces a variable density and pressure-wave velocity, the resolution scheme becomes increasingly complex. Techniques such as finite volumes are often used to improve the quality of results because of their conservative form. This paper focuses on a resolution technique for unsteady friction using the Godunov approach in a finite volume method employing single-equivalent twophase flow equations. The unsteady friction component is determined by taking into account local and convective instantaneous accelerations and the sign of both convective acceleration and velocity values. The approach is used to reproduce a set of transient flow experiments reported in the literature, and good agreement between simulated and experimental results is found.

Minimum and Maximum Temperature Trends in Congo-Brazzaville: 1932-2010  [PDF]
Gaston Samba, Dominique Nganga
Atmospheric and Climate Sciences (ACS) , 2014, DOI: 10.4236/acs.2014.43040

Maximum and minimum temperatures time series of Congo-Brazzaville are analyzed for trend and discontinuities over the period 1932 to 2010. Temperatures series show an irregular increase. A total of 8 synoptic stations show positive trends in their annual mean maximum temperature series, and 7 of them are significant, with higher trends for urban stations. Annual mean minimum temperature showed 6 stations having positive trends. This increase is in relation with observations at regional scale. However, the differences are observed between large towns (Brazzaville and Pointe-Noire), and small or rural towns (Dolisie, Sibiti, Impfondo, Djambala). Trends in diurnal temperature range (DTR) are large positive trends in maximum temperature that are mainly observed in cities. The curve of DTR shows a decreasing trend which indicates the increasing of minimum temperatures. The effects of urbanization on temperature trends are investigated. Most stations regarded as urban stations are still useful for trend analysis; being situated on the suburban of the studied cities, they are therefore, not substantially influenced by the urban heat island.

Arrival Analysis of Dry Weather Sanitary Sewer Overflows  [PDF]
Kenneth Tuffour, Chris Samba
Open Journal of Civil Engineering (OJCE) , 2016, DOI: 10.4236/ojce.2016.63038
Abstract: This study investigates arrivals of sanitary sewer overflows collected from a municipality. The data set consists of recorded overflows from 2011 to 2014 during dry weather. Reliability analysis is conducted upon each data set. The Weibull distribution is adopted to evaluate the data sets. The results show that the arrival of dry weather SSOs cannot be simply modeled with a Poisson process that is featured with a constant arrival rate. For annual data set, 2-parameter Weibull generally has an acceptable fitting (except 2014 data). The shape parameters are close to 1 or a little greater than 1, indicating relatively constant arrival rate or slightly increased rate. For the entire data set, the 3-parameter Weibull distribution is able to fit the data well. The shape parameter is also greater than 1. Therefore, an increased SSO arrival rate is noticed for this data set. There are needs to make more efforts in maintaining the sewer system.
