Case Reports in Infectious Diseases

Staphylococcus schleiferi represents an uncommon pathogen in human infections. As a veterinary pathogen, S. schleiferi causes canine ear and skin infections. Chronic osteomyelitis is a progressive process characterized by bone destruction and the formation of sequestrum. It may be a sequela of untreated or undertreated acute osteomyelitis or septic arthritis. Descriptions detailing the pathogenicity and virulence of S. schleiferi osteomyelitis were limited to a few case reports. Among the three reported cases of S...

Carbapenem-resistant Acinetobacter baumannii infection is a critically prioritized pathogen by the World Health Organization and a cause for growing concern due to increased mortality among hospitalised patients. Phrenic nerve palsy is a rare complication of herpes zoster infection of the C3, C4, and C5 nerve roots. We present a case of bloodstream carbapenem-resistant A. baumannii infection in a Ghanaian patient with HIV type 1 infection and multiple risk factors, including unilateral diaphragmatic eventration with compression atelectasis likely secondary to phrenic nerve palsy due to herpes zoster infection, consequently leading to recurrent hospital and ICU admission...

Disseminated mucormycosis is a rare life-threatening fungal infection that is uniquely seen in severely immunocompromised patients including those with hematological malignancies. We report a case of disseminated mucormycosis with a biopsy-proven gastrointestinal and oral cavity involvement in a patient with acute myeloid leukemia during induction chemotherapy. The patient had a successful outcome with limited resection of the involvement bowel segment, multiple maxillary dental extractions, debridement of the alveolus and hard palate, and combined antifungal therapy...

Considering the global spread of the coronavirus disease 2019 (COVID-19), it is expected that vaccination against its causative agent, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), will reduce the related morbidity and mortality. However, the safety of the COVID-19 vaccines and their potential and unknown side effects are a matter of concern. With the ongoing development and implementation of COVID-19 vaccination programs around the world, the side effects, safety, and effectiveness of these vaccines are gradually being reported, providing researchers with valuable information that can affect the production and utilization of the COVID-19 vaccines...

Monkeypox virus (MPXV) is one of the rare zoonotic infections caused by orthopoxvirus. MPXV has recently been an evolving threat to public health with its contagious human-to-human transmission. Various presentations of MPXV infection have been reported ranging from generalised symptoms such as fever, chills, body aches, and swollen lymph nodes to dermatological presentations. Neurological manifestations that have been reported include headaches, myalgia, seizures, and even mood disturbances. Postinfectious complications such as encephalitis, vision problems, and skin infections have also been noticed...

Visceral leishmaniasis (VL) is an infectious disease caused by protozoa of the genus Leishmania . Sporadic cases are observed in nonendemic areas and often associated with limited foci; therefore, the disease is easily overlooked. In addition, other diseases have similar clinical symptoms, which make it difficult for clinicians to make an accurate diagnosis and to provide effective treatment. We identified visceral leishmaniasis in a 4-year-old child in Pikine, Senegal. The patient was admitted to the Pikine National Teaching Hospital for haemorrhagic, tumoral, and infectious syndromes...

A liver abscess is a collection of purulent fluid in the liver parenchyma caused by a variety of etiological organisms such as bacteria, protozoa, and in rare occasions fungi. Mycobacterium tuberculosis (MTB) is a frequent and widespread infection in underdeveloped nations such as India, which can manifest in many ways. Tuberculosis mostly affects the lungs, although it can also affect any organ in the body. We are reporting a case of liver abscess caused by MTB infection in order to raise general awareness among physicians about the importance of suspecting and ruling out tuberculosis as a cause of liver abscess...

Toxoplasma gondii , an obligate intracellular parasitic protozoon, usually causes a mild, acute infection followed by a latent asymptomatic phase with tissue cysts or a chronic form with recurrent retinochoroiditis. However, immunocompromised patients can cause disseminated disease due to the reactivation of the latent tissue cysts or due to a primary infection. Here, we present a rare case of bilateral ocular toxoplasmosis and concurrent subacute toxoplasma encephalitis in a 70-year-old patient on anti-CD40 treatment following his liver transplant...

Babesiosis is a tick-borne condition that causes hemolytic anemia and manifests with flu-like symptoms such as fevers, chills, fatigue, and anorexia. Very few case reports have documented babesiosis infection associated with a false-positive HIV test. In this case report, we add to the current literature by describing a patient admitted for treatment of babesiosis who had a preliminary positive HIV test on admission and a negative repeat HIV test after one week of treatment for babesiosis. A 60-year-old male with a past medical history of high cholesterol presented to the Emergency Department after having abnormal laboratory tests with his primary care doctor...

Malaria is an infectious Anopheles mosquito-borne disease caused by five different eukaryotic protozoa parasites. Amoebiasis is a parasitic infection caused by Entamoeba histolytica . Both diseases are widespread in Liberia. A returning traveler was diagnosed and treated for malaria, and 20 days later, an amoebic liver abscess was discovered, meaning that the malaria infection masked the amoebic infection, which emphasizes the importance of a complete examination of returning travelers, especially for those returning from Sub-Saharan Africa, where coinfections are more common...

Aspergilloma (a saprophytic infection) typically colonizes lung cavities due to underlying diseases such as tuberculosis, bronchiectasis, cavitary lung cancer, sarcoidosis, and pulmonary infarctions. Rarely, aspergilloma has been noted within a hydatid cyst. Even if this was the case, it is more common to find the coexistence of aspergilloma and pulmonary echinococcal cysts in immunocompromised individuals. It is, however, very uncommon to find this coinfection in normal immune status individuals. Here, we report on the successfully treated case of a 30-year-old immunocompetent female from Western Nepal with histologically proven coinfection by these two pathogens...

We describe the case of a 13-year-old girl who presented with a new-onset seizure and fever and subsequently developed severe cardiac dysfunction, coronary artery dilation, and shock due to the surprising diagnosis of multisystem inflammatory syndrome in children (MIS-C). Although the clinical entity we now call MIS-C was first mentioned in the medical literature in April 2020, the full picture of this disease process is still evolving. Neurologic involvement has been described in cases with MIS-C; however, seizures are not a typical presenting symptom...

Tuberculosis is an important infectious disease for children worldwide. The clinical presentation of tuberculosis in children is diverse and, depending on the affected organs, it is often accompanied with nonspecific symptoms that can mimic other diseases. In this report, we present a case of disseminated tuberculosis in an 11-year-old boy with intestinal followed by pulmonary involvement. The diagnosis was delayed for several weeks due to the clinical picture which was mimicking Crohn's disease, the known difficulties in diagnostic tests and the improvement on meropenem...

A previously fit 46-year-old male handyman presented to a rural hospital with a cough, fever, and epigastric pain without peritonism. The patient was admitted medically with symptoms and radiological appearances consistent with atypical community-acquired pneumonia. During the first 48 hours of admission, he suffered a significant haemodynamic deterioration and was transferred to the intensive care unit (ICU) for vasoactive support. Following stabilisation, urgent abdominal CT imaging demonstrated splenic rupture with haematoma in the absence of historical trauma...

BACKGROUND: Hepatitis is one of the common infectious diseases that can infect patients in various forms. Based on their characteristics and clinical features, they can cause irreparable complications in patients. Coinfections and superinfections between its variant have been reported, but the coinfection of acute HAV and HBV is rarely reported. Case Presentation . In this case report, we presented a case with severe malaise, nausea, vomiting, generalized jaundice, and a history of recent tattooing and travel to the HAV endemic area...

Cerebritis and infective endocarditis caused by Listeria monocytogenes are very rare. A 56-year-old man presented with slurring of speech and generalized body weakness of 1 week duration. He did not have any past medical history. On systemic examination, he had mild slurring of speech and facial asymmetry and was initially treated for multifocal chronic cerebral infarcts. Listeria monocytogenes was isolated from blood culture on day 5 of admission. A diagnosis of neurolisteriosis was made as contrast-enhanced-computed tomography (CECT) of the brain showed right frontal cerebritis...

Persistent fever due to coronavirus disease 2019 (COVID-19) is a considerable issue for patients and physicians that requires a broad differential diagnosis and evaluation of complications. Coinfections with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and various respiratory viruses have also been reported. In severe cases of COVID-19, cytomegalovirus (CMV) reactivation or CMV coinfection with SARS-CoV-2 has been reported in association with critical illnesses and immunosuppressive therapy; however, in mild COVID-19 cases, CMV coinfection with SARS-CoV-2 has been reported only in severely immunocompromised patients, and its incidence and clinical importance remain unclear...

Acute disseminated encephalomyelitis (ADEM) is an autoimmune neurological disease that predominately affects pediatric population. Only a single fatal adult case of adenovirus-associated ADEM has previously been published by Qamar et al. in 2021. Here, we present an adult case of adenovirus-associated ADEM, which was diagnosed early in her clinical course. The patient was treated with the prompt initiation of steroids, intravenous immune globulin (IVIG), and plasmapheresis (PLEX), and the patient recovered fully...

Strongyloidiasis develops from the infection with Strongyloides stercoralis (Family: Strongylidae) and was recently considered a neglected tropical disease by the World Health Organization due to its global distribution and high burden of infection. Here, we present the cases of two patients under corticosteroid therapy after neurosurgical surgery who developed septic shock-like hyperinfection syndrome due to disseminated strongyloidiasis. The first case is a 77-year-old man from Cape Verde who was diagnosed with an extra-axial right parietal brain mass...

Roseomonas mucosa ( R. mucosa ) is a pink-pigmented, aerobic, nonfermentative, slow-growing Gram-negative coccus typically isolated from the natural environment, human skin, and hospital environment. This pathogen, in most circumstances, leads to infections in immunocompromised hosts, but it may sometimes invade immunocompetent individuals. Bacteraemia is the most common form of infection caused by R. mucosa . In contrast, only two case reports have described R. mucosa -related epidural abscess formation and infective spondylitis...
