[Basicervical ectopic goiter associated with a eutopic thyroid gland: a case report]. / Une association d'un goitre ectopique basi-cervical et d'une glande thyroïde eutopique: à propos d'un cas.

Thyroid gland is an endocrine gland playing a major role in energy and phosphocalcic metabolism, among others. It commonly occurs in the anterior cervical and pretracheal region. Ectopic thyroid is quite rare. It is dominated by ectopic basilingual thyroid. We here report the case of a patient with goiter in normal cervical position (eutopic) and ectopic thyroid tissue in basicervical position. Cervicotomy revealed the ectopic nodule and the diagnosis was confirmed by histology. This clinical case illustrates a differential diagnosis of cervical masses.

Case Report: Lingual Tuberculosis Reveaed by a Cold Abcess.

Tuberculosis is the most common infectious disease in the world and the lingual location represents less than 1% of extra-pulmonary forms. We report a case of primary lingual tuberculosis which was presented to us in the form of a cold abscess in a 46-year-old alcohol and tobacco drinker weaned for 01 years. Confirmation was histological after biopsy of the lesion. Treatment with anti-tuberculosis drugs for 06 months resulted in a cure. Primary tuberculosis of the tongue is rare and can take several macroscopic forms, including cold abscess which is exceptional. A histological examination after biopsy will make the diagnosis.

[Retropharyngeal abscess: case study of 5 cases and literature review]. / Abcès rétropharyngé et la revue de la littérature: à propos de 5 observations.

The purpose of this study was to perform correlation of 5 cases and literature review. The study involved both children and adults. The major cause of retropharyngeal abscess was fish bone foreign body. Dysphagia associated with pain, fever and torticollis were the most common symptoms. Retropharyngeal abscess mainly occurred in the oropharyngeal and hypopharyngeal regions. Imaging tests, in particular CT scan, allowed for accurate information in 3 cases. Aerodigestive tract obstruction was found in most of our patients. Only 4 patients underwent incision and drainage. All patients received medical treatment. A 2-year-old died 5 days after surgery due to septic shock. This study highlights the rarity of this condition in our context as well as the importance of early diagnosis and treatment to prevent life-threatening complications.

[Anosmia without aguesia in COVID-19 patients: about 2 cases]. / Anosmie sans agueusie chez des patients COVID-19: à propos de 2 cas.

During the ongoing pandemic, anosmia, whether or not associated with aguesia, has been a common symptom in patients with SARS-CoV-2 infection causing COVID-19. We here report two cases of anosemia without aguesia in adults with COVID-19. The onset was brutal and symptomsa persisted for a few weeks after healing. The patients presented to the ENT Department where they received no therapy and underwent outpatient surveillance. After 5 weeks, patients reported they had recovered the sense of smell. This study highlights that anosmia can occur without aguesia and persist after healing in COVID-19 patients. Recovery of the smell is possible after a few weeks without medical treatment. That is why, patients follow-up is essential in subjects recovered from COVID-19 to better understand the course of persistent symptoms.

The malaria co-infection challenge: An investigation into the antimicrobial activity of selected Guinean medicinal plants.

ETHNOPHARMACOLOGICAL RELEVANCE: In sub-Saharan Africa, concomitant occurrence of malaria and invasive infections with micro-organisms such as Gram-positive Staphylococcus aureus, Gram-negative Escherichia coli and yeasts or fungi such as Candida albicans and Aspergillus fumigatus is common. Non-tuberculous mycobacteriosis caused by Mycobacterium chelonae has been recognized as a pulmonary pathogen with increasing frequency without effective therapy. Although less important, the high incidence of Trichophyton rubrum infections along with its ability to evade host defense mechanisms, accounts for the high prevalence of infections with this dermatophyte. Considering the treatment cost of both malaria and microbial infections, along with the level of poverty, most affected African countries are unable to cope with the burden of these diseases. In sub-Saharan Africa, many plant species are widely used in the treatment of these diseases which are traditionally diagnosed through the common symptom of fever. Therefore it is of interest to evaluate the antimicrobial activities of medicinal plants reported for their use against malaria/fever. MATERIALS AND METHODS: Based on an ethnobotanical survey, 34 Guinean plant species widely used in the traditional treatment of fever and/or malaria have been collected and evaluated for their antimicrobial activities. Plants extracts were tested against Candida albicans, Trichophyton rubrum, Aspergillus fumigatus, Mycobacterium chelonae, Staphylococcus aureus and Escherichia coli. RESULTS: The most interesting activities against Candida albicans were obtained for the polar extracts of Pseudospondias microcarpa and Ximenia americana with IC50 values of 6.99 and 8.12 µg/ml, respectively. The most pronounced activity against Trichophyton rubrum was obtained for the ethanol extract of Terminalia macroptera (IC50 5.59 µg/ml). Only 7 of the 51 tested extracts were active against Staphylococcus aureus. From these, the methanolic extracts of the leaves and stem bark of Alchornea cordifolia were the most active with IC50 values of 2.81 and 7.47 µg/ml, respectively. Only Terminalia albida and Lawsonia inermis showed activity against Mycobacterium chelonae. None of the tested extracts was active against Escherichia coli. CONCLUSION: A number of traditional Guinean plant species used against malaria/fever showed, in addition to their antiplasmodial properties and antimicrobial activity. The fact that some plant species are involved in the traditional treatment of malaria/fever without any antiplasmodial evidence may be justified by their antimicrobial activities.

In vitro antiprotozoal and cytotoxic activity of ethnopharmacologically selected guinean plants.

Based on an ethnobotanical survey, 41 Guinean plant species widely used in the traditional treatment of fever and/or malaria were collected. From these, 74 polar and apolar extracts were prepared and tested for their in vitro antiprotozoal activity along with their cytotoxicity on MRC-5 cells. A potent activity (IC50 < 5 µg/mL) was observed for Terminalia albida, Vismia guineensis, Spondias mombin, and Pavetta crassipes against Plasmodium falciparum; for Pavetta crassipes, Vismia guineensis, Guiera senegalensis, Spondias mombin, Terminalia macroptera, and Combretum glutinosum against Trypanosoma brucei brucei; for Bridelia ferruginea, G. senegalensis, V. guineensis, P. crassipes, and C. glutinosum against Trypanosoma cruzi. Only the extract of Tetracera alnifolia showed a good activity (IC50 8.1 µg/mL) against Leishmania infantum. The selectivity index of the active samples varied from 0.08 to > 100. These results may validate at least in part the traditional use of some of the plant species.

Management of diabetes in Guinean traditional medicine: an ethnobotanical investigation in the coastal lowlands.

ETHNOPHARMACOLOGICAL RELEVANCE: This survey was carried out in the coastal lowlands of Guinea-Conakry in order to make an inventory of plants used by traditional healers, herbalists and diabetic patients for the management of diabetes mellitus. MATERIALS AND METHODS: Frequent ethnomedical and ethnobotanical investigations were conducted from June 2008 to December 2009 in Conakry, Kindia, Forécariah, Dubréka, Boke, Fria and Boffa. It is a cross-sectional survey and data collection is based on the interactive method. During this period a total of 112 people aged from 39 to 76 years old were interviewed. RESULTS: During this investigation 146 plant species belonging to 55 families were collected. The most cited plants were Anacardium occidentale L. and Ficus spp., while the Fabaceae family was the most represented, followed by the Euphorbiaceae and Rubiaceae. The most frequently plant parts used by the traditional healers and the herbalists were the stem-bark and decoctions the most common preparation mode. CONCLUSIONS: It is clear that a variety of plants is used in the management and treatment of diabetes. Due to the increasing prevalence of type 2 diabetes, there is an urgent need for scientific investigations to rationalise the use of these traditional remedies, which could represent accessible alternative medicines for the Guinean populations.
