Objective: To assess the effectiveness of ultrasound-guided supraginguinal block (SIB) in the management of pain after total hip replacement. Material and Methods: This was a prospective, randomized, single-blind controlled study carried out in the anesthesia-intensive care unit of the Donka National Hospital in Conakry, over a period of 06 months (01/01/2020 to 30/06/2020). It concerned 32 patients: 16 patients in the “ultrasound-guided SIB” group and 16 patients in the “standard analgesia” group. Results: The pain scores assessed by the simple verbal scale and collected at the different time intervals (6H, 12H, 24H, 36H, 48H) showed mean scores 3 in the standard analgesia group (P Conclusion: Our study demonstrated that echo-guided SIB provided better analgesia compared to standard analgesia for the management of postoperative pain after total hip replacement.

The unequal access to healthcare in general and oral healthcare, in particular, is a true public health concern. Thus, it is important to assess the oral healthcare renunciation and socioeconomic determinants to take appropriate measures. A cross-sectional, descriptive population-based study of 300 households was carried out between April 28, 2016, and May 28, 2016, according to WHO’s guidelines (Protocol 1997), in Senegal adapted form. Results showed that 18.23% of householders report that their household members have foregone oral healthcare. Among those who renounced care, 51.5% did so for care costs (24.2%) or remoteness of health facilities (27.3%) reasons. Therefore, dental treatment renunciation was independently associated to income level, age, sex, marital status, and types of oral healthcare coverage. This study’s analysis shows that oral healthcare renunciation depends primarily on the financial aspect and the remoteness of health structures. Still, there are other important socio-anthropological parameters that should be investigated.

The monochromatic absorption coefficient of silicon, inducing the light penetration depth into the base of the solar cell, is used to determine the optimum thickness necessary for the production of a large photocurrent. The absorption-generation-diffusion and recombination (bulk and surface) phenomena are taken into account in the excess minority carrier continuity equation. The solution of this equation gives the photocurrent according to absorption and electronic parameters. Then from the obtained short circuit photocurrent expression, excess minority carrier back surface recombination velocity is determined, function of the monochromatic absorption coefficient at a given wavelength. This latter plotted versus base thickness yields the optimum thickness of an n+-p-p+ solar cell, for each wavelength, which is in the range close to the energy band gap of the silicon material. This study provides a tool for improvement solar cell manufacture processes, through the mathematical relationship obtained from the thickness limit according to the absorption coefficient that allows base width optimization.

We evaluate the level of knowledge of clinician doctors asking for echographies on the biological effects of ultrasounds and their attitudes towards ultrasounds examinations performed in Lome. Transverse study based on a survey led from August 16th till November 30th, 2013 including 105 doctors applicant of ultrasound in Lome (Togo). The middle age of the applicant doctors was of 34 years with a sex-ratio of 4/1 and more than half practiced in public facilities. Approximately ten percent applicants thought that the ultrasound is an irradiant exam and those practicing for less than 5 years were the ones who had a good level of knowledge on the not irradiant character of the ultrasounds. The existence of the thermal and mechanical effects of the ultrasounds was known only by 4.8% of the applicants and only 1.9% of the doctors had information on the thermal index (TI) and the mechanical index (MI). More than half (66.7%) analyzed the ultrasound images joined to the report but none verified the conformity with the standards of the values of the TI and at MI shown on the images. They were 43.5% to read only the conclusion. The level of knowledge of the doctors on the biological effects of the ultrasounds is unsatisfactory. The ultrasounds although not irradiant, have biological effects imposing precautionary measures which have to guide the attitude of the applicants towards the ultrasonographic explorations.

Perforation of a pseudo appendicular tumor of bilharzial origin (bilharzia) is a rare etiology of acute peritonitis. His diagnosis is histopathological. The existence of comorbid malaria and surgical pathology is frequent in having a positive thick drop with Schistosoma mansoni eggs in his stool. After 3 months, the patient is doing well. In conclusion, we recommend the histopathological analysis of the surgical specimen after appendectomy and the detection of haematozoa for malaria in any case of fever in a surgical environment.

We report the case of a 39-year-old patient with a history of chronic gastritis, functional colopathy and appendectomy, referred by another public institution for severe abdominal pain. He had been admitted 6 days previously for nausea, vomiting, diarrhea, fever, asthenia since the onset of dyspnea with 89% desaturation in ambient air and a dry cough. A diagnosis of gastroenteritis was made and treated without success. The appearance of abdominal distension and bloating motivated his transfer to the CTPI where the rRT-PCR was carried out positive and an X-ray of the abdomen without preparation which had demonstrated a significant aerocoly with agglutination of handle. Surgical management under general anesthesia found a clean cavity after coeliotomy, multiple intestino-intestinal, intestino-parietal and omentum-parietal adhesions. The gesture consisted of an adhesiolysis, omentectomy. The postoperative follow-up was favorable with resumption of transit on D5 postoperative. Put under the COVID-19 treatment protocol, the rRT-PCR was negative on D13, output on D14 and removal of the D19 files without postoperative complications.

We report the case of a 28-month-old male child with no particular history who was admitted to the emergency room for severe abdominal pain associated with vomiting, asthenia and fever at 39.1˚C that had progressed for 4 days. He was conscious, polypneic at 32 cycles/min on admission. On palpation the abdomen was distended, painful as a whole, more pronounced in the epigastrium. There was abdominal contracture, generalized defense, a cry with sudden decompression of the umbilicus. On abdominal auscultation, there was a disappearance of prehepatic dullness, a decrease in the dullness of the flanks and absence of hydro-aeric noises. On the digital rectal examination, Douglas’s cul de sac was bulging and sensitive. An unprepared X-ray of the abdomen revealed diffuse grayness, lateral gas crescent pneumoperitoneum under diaphragm. The preoperative resuscitation consisted of the placement of a nasogastric tube, a urinary catheter, a peripheral venous route and the fluid electrolyte rebalancing adapted according to the blood ionogram, early antibiotic therapy with broad aero and anaerobic spectrum. Surgical management under general anesthesia found at laparotomy a perforation of the anterior surface of the duodenal bulb which we estimate to be 1 cm in diameter with fibrin deposits. The gesture was the toilet of the peritoneal cavity;suture of the bank and the operative consequences were simple.

Introduction: Due to its health, social and economic morbidity, dental caries leads to absenteeism and a drop in school performance among schoolchildren. The objective of this work is to study dental caries and its determinants in pupils known as Children of Troop (CT) of the “Military School of Saint Louis” (MSS). Method: This was a descriptive and cross-sectional study. Recruitment was exhaustive. The collection was made at the school and has covered the period of March 10 throughout June 13, 2014 in an individual interview, based upon a deliberate consent, using a questionnaire drawn up on the basis of the variables studied. The bivariate analysis was done with the Epi Info software version 3.5.3. Results: The mean age of CT was 14.9. The prevalence of caries was 61.2%. Determinants related to caries were: sugar intake between meals (OR = 6.44 [3.4 - 11.9]);insufficient tooth brushing (OR = 14.3 [8.8 - 23.29]);(OR = 3.84 [2.38 - 7.14]) and for regular dental visits (OR = 5.26 [3.44 - 8.33]), with the last dental visit dating back more than one year. Conclusion: In the face of challenges of school performance of CT, it is necessary to set up a control plan focusing mainly on the factors identified and associated with dental caries in military school.

“Locked twins” is a rare event occurring in about 1 in every 1000 twin births. A 21-year-old primigravida with a 31-week twin pregnancy was admitted for delivery. The head of the first twin was locked to the chin of the second twin at the top of the symphysis pubis. Caesarean section was performed allowing the delivery of both dead twins. Twins gestations with first twin in the breech presentation raise index of suspicion of potential locked twin. However, management of such situation is controversial with most authors and colleges recommending caesarean section to avoid interlocking heads. We report another rare case of interlocking heads and bring up the topic about management of breech-first twin deliveries.
