Key Clinical Message: In countries like Sudan, where several infectious diseases are prevalent, health care providers should not be satisfied with initial detection of a single pathogen and whenever it is feasible, they should investigate coinfections. Infections with high mortality or severe morbidity should be prioritized during the differential diagnosis particularly for diseases with similar clinical manifestations to reduce the death and disability rates. However, this requires substantial improvement in the diagnostic capacity. Abstract: Here we report a case of dengue and malaria coinfection from the southeast region of Sudan, bordering Ethiopia and Eritrea. A 25-year-old male from Sudan presented with symptoms of fever, chills, vomiting, and muscle and joint pain. Laboratory investigations confirmed a coinfection of dengue and malaria, which is assumingly not uncommon in areas heavily syndemic with several diseases but it is severely under-detected, underreported, and underestimated. The case has fully recovered after the supportive care for dengue and chemotherapy treatment for malaria. In such a case, it was important to monitor the patient's recovery and the treatment outcome through clinical indicators and laboratory parameters to update the treatment course whenever needed, according to response. The increasing burden and outbreaks of vector-borne diseases including dengue and malaria in Sudan, indicates the need for improving the implementation of the global vector control response that established by the World Health Organization. Additionally, the increasing prevalent of coinfections is urging substantial improvement in the diagnostic capacity in endemic countries.
Key Clinical Message: Atypical presentations of eumycetoma can pose a challenge in the diagnosis and treatment of the disease. Healthcare providers thorough in their differential diagnosis and investigations, even in the absence of classic symptoms, in order to improve early detection and the case management for such a neglected tropical disease. Abstract: In this communication, we present a case study of an unusual presentation of eumycetoma; a fungal infection that is considered a neglected tropical disease. The patient, a 28-year-old male from Sudan, presented with a recurrent mass in the abdominal wall. Despite two surgeries to remove the mass, it continued to recur. Unlike typical cases of eumycetoma, this patient did not exhibit common symptoms such as painless swelling, sinuses, or grain-containing discharge. The diagnosis was made incidentally after surgical excision of the mass. The abstract highlights the importance of recognizing uncommon presentations and maintaining a high suspicion for rare diagnoses, even in the absence of classic symptoms. Further research is needed to better understand atypical presentations of eumycetoma and improve early detection.
BACKGROUND: Mycetoma is a chronic disease affecting the skin and subcutaneous tissue endemic in the tropical and subtropical regions. Several bacteria and fungi can cause mycetoma, but fungal mycetoma (eumycetoma) is challenging because the treatment requires a combination of a long-term antifungal agent and surgery. Although the transmission route has not yet been elucidated, infection from the soil is a leading hypothesis. However, there are few soil investigation studies, and the geographical distribution of mycetoma pathogens is not well documented. Here, we used multiplex real-time PCR technology to identify three fungal species from soil samples. METHODS: In total, 64 DNA samples were extracted from soil collected in seven villages in an endemic area in Sennar State, Sudan, in 2019. Primers and fluorescent probes specifically targeting the ribosomal DNA of Madurella mycetomatis, Falciformispora senegalensis, and F. tompkinsii were designed. RESULTS: Multiplex real-time PCR was performed and identified the major pathogen, M. mycetomatis that existed in most sites (95%). In addition, two other pathogens were identified from some sites. This is the first report on the use of this technique for identifying the eumycetoma causative microorganisms. CONCLUSIONS: This study demonstrated that soil DNA investigation can elucidate the risk area of mycetoma-causative agents. The results will contribute to the design of prevention measures, and further large-scale studies may be effective in understanding the natural habitats of mycetoma pathogens.
Key Clinical Message: This case report highlights the role of Helicobacter pylori infection in the development of GBS. Healthcare providers should consider H. pylori in their differential diagnosis for patients with neurological syndromes. Astract: We report the first known case of Guillain-Barré syndrome (GBS) associated with Helicobacter pylori infection in Sudan. This case highlights the role of H. pylori infection in the development of GBS. It also emphasizes the importance of wide screening of different endemic infections for patients with neurological syndromes for early detection and improves the case management in resource-limited settings like Sudan. Further research is needed to better understand the underlying mechanisms of H. pylori-inducing neurological disorders.
Key Clinical Message: In endemic areas, malaria-induced cerebellar ataxia should be suspected in patients presenting with neurological disorders including slurred speech, tremors, and a sense of imbalance and dizziness while walking. Healthcare providers should be aware to properly investigate and early detect and manage infections associated with the development of cerebellar ataxia to improve the case management and clinical outcome cost-effectively. Abstract: Here, we report the clinical manifestations, investigations, and outcomes of a patient developed delayed cerebellar ataxia following a malaria infection: an unusual complication of the disease. This report highlights the diagnostic challenges in a country endemic with several infectious diseases, yet it has a limited diagnostic and surveillance capacity.
OBJECTIVES: Hashimoto's thyroiditis (HT) is the most common cause of hypothyroidism. The exact mechanism initiating the development of HT is not yet clear. This study aimed to investigate the correlation between HT and the presence of Epstein-Barr virus (EBV) in a Sudanese population. RESULTS: EBV-LMP1 was detected in 11.1% of HT cases, which is consistent with previous studies. Studies have reported a wide range of frequencies indicating the presence of EBV in HT, and patients with autoimmune thyroiditis have increased titers of anti-EBV antibodies in their sera compared to healthy subjects. Intrathyroidal EBV-infected B cells may be responsible for the increased risk of development of B-cell lymphoma in the thyroid gland in patients with autoimmune thyroiditis. Our study suggests that regular follow-up is necessary for patients diagnosed with HT and are positive for EBV, as antiviral therapy is not applicable due to the risk of thyroid dysfunction. The study suggests an association between EBV and HT, but causation cannot be determined. The study also highlights the need for further research to determine the viral role and correlate it with the severity and progression of HT.

Key Clinical Message: This case presents an atypical cystic presentation of mycetoma without sinuses or discharge. Awareness of these variations is crucial for accurate diagnosis and timely intervention, highlighting the need for healthcare professionals to consider diverse manifestations of mycetoma. Abstract: Mycetoma is a chronic and debilitating infectious disease characterized by localized swellings and granulomatous lesions. It primarily affects individuals in tropical and subtropical regions and is caused by certain fungi or bacteria. While mycetoma typically presents with sinuses and discharge, this case report presents a unique cystic presentation without these features. The patient, a 12-year-old female from Sudan, presented with a painless swelling on the dorsum of her right foot. Physical examination revealed a round, non-tender, and fluctuant mass. Histopathological examination confirmed actinomycetoma caused by Streptomyces somaliensis. The patient was successfully treated with a combination of antibiotherapy. This atypical presentation underscores the need for healthcare professionals to consider uncommon variations of mycetoma for accurate diagnosis and management.
Key Clinical Message: Hepatitis E virus (HEV) infection can be manifested with several neurological syndromes including GBS. Therefore, healthcare providers should consider HEV in their differential diagnosis for patients with neurological disorders. Abstract: We report a case of Guillain-Barré syndrome associated with hepatitis E virus infection. The current case-report demonstrates diagnostic challenge to identify GBS case in a limited-resources country like Sudan. However, HEV infection should be highly suspected in patients with neurological manifestation with high liver enzymes.
Key Clinical Message: We report a case of febrile illness that was presented with mild symptoms. However, laboratory investigation confirmed a malaria and Rift Valley fever co-infection. Healthcare providers in settings endemic with several infectious diseases should seek rolling out possibilities of other infections prior to starting treatment for achieving effective case management with less resources and better safety of patients. Abstract: Here we report a case of febrile illness that confirmed to be a co-infection of malaria and Rift Valley fever. The patient was initially diagnosed with malaria and started on treatment immediately. However, due to the lack of response to the treatment further laboratory investigations were pursued.
BACKGROUND: Filamentous fungi of the genus Madurella are the primary causative agents of mycetoma, a disease observed in tropical and subtropical regions. Since early diagnostics based on a morphological approach are difficult and have many shortcomings, a molecular diagnostic method suitable for rural settings is required. In this study, we developed the loop-mediated isothermal amplification (LAMP) method to present a foundational technique of the diagnosis of Madurella spp. (M. mycetomatis, M. pseudomycetomatis, M. tropicana, and M. fahalii), the common causative organisms of eumycetoma. PRINCIPAL FINDINGS: We successfully designed a primer pair targeting the rDNAs of three Madurella spp. excluding M. fahalii, and detected up to 100 fg of genomic DNA extracted from isolates of M. mycetomatis and 1 pg of M. pseudomycetomatis and M. tropicana, within one hour. Second, a primer pair specific to M. mycetomatis, the most common causative species, or M. fahalii, a drug-resistant species, was constructed, and the detection limit of both primer pairs was 1 pg. The designed primers accurately distinguished 16 strains of the genus Madurella from various fungal species known to cause mycetomas. CONCLUSION: In summary, we established the first model of a LAMP detection method that rapidly and sensitively detects and identifies Madurella isolates for clinical diagnostics. Moreover, the combined designed primer sets could identify mycetoma-causing strains simultaneously.

Eumycetoma is an infectious disease caused by various fungal pathogens. The disease is characterised by black and pale-yellowish grain discharge. In this communication, we report a case of eumycetoma with a pale grain foot-eumycetoma caused by Fusarium falciforme. The patient presented at the outpatient clinic of the Mycetoma Research Centre in Sudan. The causative agent was initially misidentified as Aspergillus nidulans based on its seemingly similar histopathological appearance. However, sequencing the internally transcribed spacer region of the extracted grain confirmed infection with Fusarium falciforme. Although the patient received Itraconazole and underwent surgical excision, the disease was recurrent. To our knowledge, this is the first report on Fusarium falciforme causing eumycetoma in Sudan, indicating the expansion of the geographical distribution of this pathogen. This calls for raising the awareness of healthcare providers and improving the diagnostic and surveillance systems in at-risk areas to improve the case management and reduce the threat of further spread. Considering the potential impacts of F. falciforme infection including threatening the global health, food security, and ecosystem balance, as well as loss of biodiversity and negative socioeconomic changes in endemic countries, we recommend the implementation of an integrated transdisciplinary One Health strategy for the prevention and control of emerging infectious diseases including F. falciforme.
Artificial Intelligence (AI) has proven to be an effective tool in predicting, detecting, and mitigating the spread of infectious diseases, especially during the COVID-19 pandemic. The technology is increasingly playing a role in preventing future health crises by predicting outbreaks, identifying high-risk areas, and aiding in vaccine development. AI can track and trace infected individuals and identify potential hotspots, help reduce the spread of infectious diseases, and monitor patient symptoms, enabling healthcare professionals to provide effective treatment.

Key Clinical Message: In a resource-limited setting such as Sudan, where diagnostic and surveillance capacities are limited and several dermal diseases with similar clinical presentation are endemic, further precautious must taking into account. Abstract: Cutaneous tuberculosis (CTB) is a rare infection caused by Mycobacterium tuberculosis. Atypical clinical presentations of CTB may resemble other skin neglected diseases. For definitive diagnosis, we require a holistic diagnostic approach including clinical examination and deployment of laboratory investigations including microbial culture, histopathological, and molecular examinations of the proper samples per test. In this communication, we report a case of CTB that was initially misidentified clinically as mycetoma.
Cutaneous larva migrans (CLM) is a self-limiting dermatosis parasitic disease that is caused by zoonotic hookworm mainly infects cats, dogs, and accidentally humans. The disease affects hosts through the invasion and the migration of the hookworm larva into top layers of the skin. The disease occurs in tropical and subtropical regions; where people commonly are infected when sitting or barefoot walking on places contaminated with feces of infected cats or dogs. Due to self-limiting nature of the disease, the exact burden and prevalence are commonly underestimated. In this communication, we investigated all cases presented to the skin-diseases outpatient clinic' at the reference hospital of Tropical Diseases Medicine in Khartoum state between January 2019 and January 2021. This is the first-ever a case series report of cutaneous larva migrans in Sudan. We identified 15 cases of CLM presented with rash (100 %), redness of skin (67 %), and only adults were presented with larva crawling under their skins (27 %). Infection sites were (53 %) leg, (40 %) foot, only 7 % showed abdominal infection. The majority of patients were children or young adults, 47 % of them are ≤5 year-old, male to female ratio is 2.75:1. Duration of infection was one to three weeks and all patients fully recovered after treatment with albendazole. This urges for One Health interventions including deworming cats and dogs, improving water, sanitation, and hygiene, community-engagement and raising awareness in area with risk of infection.
BACKGROUND: Cervical cancer is considered the third leading cause of death among women worldwide, and human papillomavirus was identified as a major causative agent for developing cervical cancer. OBJECTIVES: This study aimed to assess the knowledge and attitudes towards cervical cancer prevention among women in Khartoum state, Sudan. DESIGN: A community-based cross-sectional study implemented in Khartoum state, Sudan, from 1 August 2020 to 1 September 2020. METHODS: We conducted a descriptive cross-sectional community-based study using an electronic questionnaire for data collection. Descriptive statistics, frequency, mean, and percentage were computed. RESULTS: The study included 716 female participants with a mean age of 27.6 + 8.7 years. 580 (81.0%) and 229 (32.0%) had heard about cervical cancer and Pap test, respectively. cervical cancer was assumed related to alcohol consumption 109 (15.2%), giving birth to many children 51 (7.1%), ageing 118 (16.5%), and having many sexual partners 335 (46.8%). In addition, 300 (41.9%) attributed cervical cancer to having human papillomavirus infection, 256 (35.6%) to the prolonged use of contraceptives, and 162 (22.6%) to smoking. Knowledge about the best time to be vaccinated against human papillomavirus, 110 (15.4%) stated it is better after marriage. Regression models to predict the effectors on participants' knowledge and attitudes showed a low standard deviation of the estimates with higher values of the adjusted R2 [R: 0.041, 0.017, and 0.006; std: 1.527, 0.417, and 0.426]. This indicates the combined influence of occupation, educational level, family income, and marital status on the participant's knowledge and attitude levels. CONCLUSION: This study revealed that the participant's knowledge and attitudes levels are mainly driven by their occupation, educational level, family income, and marital status altogether. This underscores the need for a countrywide community engagement campaign through health education and raising awareness sessions, and massive social media to sensitize the community and healthcare providers about the risk of cervical cancer and the available prevention and control measures.
