Despite the high prevalence of tuberculosis (TB) worldwide, pancreatic TB is rare. When present, pancreatic TB is frequently associated with miliary TB, often in immunocompromised hosts. Pancreatic TB may present as a pancreatic abscess, acute or chronic pancreatitis, and cystic or solid pancreatic masses. We present a case of an immunocompetent patient who presented with two discrete pancreatic masses and was subsequently diagnosed with isolated pancreatic TB. This case suggests that clinicians should have a heightened suspicion of pancreatic TB when faced with discrete pancreatic lesions, especially in patients from areas where the infection is endemic. Such recognition may lead to appropriate diagnostic testing, and possible resolution of pancreatic lesions with antituberculin therapy.

Nocardia is a genus of aerobic, non-motile and non-spore-forming filamentous branching bacteria with fragmentation into bacillary or coccoid forms. Infections caused by Nocardia often occur in immunocompromised hosts and are potentially life-threatening. Nocardia beijingensis has rarely been reported to cause infection in immunocompetent hosts. We present a case of disseminated infection due to Nocardia beijingensis in a patient with no known medical comorbidities, who presented with new-onset seizure. Another interesting finding in our case is that our patient did not have any pulmonary symptoms despite chest CT showing the pulmonary system as the likely primary site of infection. As per our literature review, this is the seventh reported case of infection due to Nocardia beijingensis in an immunocompetent host.

<em>Leptotrichia species </em>(LS) is an anaerobic Gram negative bacillus in the <em>Bacteroidaceae</em> family and part of the normal human oral flora. It is rarely pathogenic, but occasionally causes diseases in immunocompromised hosts. I am reporting a case of cavitary pneumonia caused by LS in an immunocompetent host.

Supravalvular aortic stenosis is the rarest form of left ventricular outflow tract obstruction. Aspergillus endocarditis is also rare and generally reported in immunocompromised hosts. Here we present a case of an immunocompetent patient with supravalvular aortic stenosis complicated by aortic mycotic pseudoaneurysm due to invasive aspergillosis.

An important assumption for DNA fingerprinting ofMycobacterium tuberculosis is that patients are infected with only one strain at a time. Nonetheless, we demonstrate a case of simultaneous infection with two drug-susceptible strains of M. tuberculosis in an immunocompetent patient by IS6110restriction fragment length polymorphism and spoligotyping. Epidemiological data prove the patient's involvement in two independent clusters. Thus, double infections should be suspected with fingerprints showing divergent band intensities.

Introduction: Cerebral aspergillum is rare and usually misdiagnosed because its presentation mimics tuberculous meningitis, brain abscess, or tumor. The diagnosis and treatment of central nervous system (CNS) infections due to Aspergillus are very difficult because accurate diagnosis is often made intra-operatively. Case Presentation: Here, we report a case of cerebral aspergilloma in an immunocompetent host. A 35-year-old man admitted with progressive left hemifacial paresthesia followed by severe pain in trigeminal nerve territory. On physical examination, except for fifth nerve palsy and difficult mastication, there was not any sensory and motor deficit. Magnetic resonance imaging (MRI) of the brain showed T1 iso and T2 low signal lesion in the left parasellar region with enhancement. The lesion is extended to the left side of the prepontine cistern in the course of trigeminal nerve, craniotomy, and total surgical resection of the mass was performed. Isolated brain lesion and the pathology from stereotactic biopsy confirmed cerebral aspergillosis. The result of testing for human immunodeficiency virus (HIV) was negative. Although the patient had two subsequent recurrences, at first, good outcome was achieved by treatment with a combination of surgical intervention, and antifungal amphotericin B deoxycholate was administered, then changed to voriconazole. Unfortunately, after two years, he experienced new progressive symptoms, and the patient died despite several reoperations due to malfunctioning of external ventricle devices as well as the treatment of recurrent post-operation meningitis and voriconazole therapy. Conclusions: Most cases of intracranial aspergillosis show that this infection is pathogenic in immunocompromised hosts; however, in some cases, invasive Aspergillus was reported as an opportunistic infection in immunocompetent patients. In these patients, though primary cranial aspergillosis is very rare, it is possible that isolated brain involvement in a previously healthy case may be explained by unknown defects in immune pathways or massive exposure to spores.

AbstractThe COVID-19 pandemic has illustrated the importance of rapid, accurate diagnostic testing for the effective triaging and cohorting of patients and timely tracking and tracing of cases. However, a surge in diagnostic testing quickly resulted in worldwide competition for the same sample preparation and real-time RT-PCR diagnostic reagents (rRT-PCR). Consequently, Hampshire Hospitals NHS Foundation Trust, UK sought to diversify their diagnostic portfolio by exploring alternative amplification chemistries including those that permit direct testing without RNA extraction. This study describes the validation of a SARS-CoV-2 RT-LAMP assay, which is an isothermal, autocycling, strand-displacement nucleic acid amplification technique which can be performed on extracted RNA, “RNA RT-LAMP” or directly from swab “Direct RT-LAMP”. Analytical specificity (ASp) of this new RT-LAMP assay was 100% and analytical sensitivity (ASe) was between 1×101 and 1×102 copies when using a synthetic DNA target. The overall diagnostic sensitivity (DSe) and specificity (DSp) of RNA RT-LAMP was 97% and 99% respectively, relative to the standard of care (SoC) rRT-PCR. When a CT cut-off of 33 was employed, above which increasingly, evidence suggests there is a very low risk of patients shedding infectious virus, the diagnostic sensitivity was 100%. The DSe and DSp of Direct-RT-LAMP was 67% and 97%, respectively. When setting CT cut-offs of ≤33 and ≤25, the DSe increased to 75% and 100%, respectively. Time from swab-to-result for a strong positive sample (CT < 25) was < 15 minutes. We propose that RNA RT-LAMP could replace rRT-PCR where there is a need for increase in throughput, whereas Direct RT-LAMP could be used as a screening tool for triaging patients into appropriate hospitals wards, at GP surgeries and in care homes, or for population screening to identify highly contagious individuals (“super shedders”). Direct RT-LAMP could also be used during times of high prevalence to save critical extraction and rRT-PCR reagents by “screening” out those strong positives from diagnostic pipelines.

This paper presents the results of a study of periodontal status in patients with chronic pancreatitis. The study established the high prevalence of periodontal disease in individuals with chronic pancreatitis.The disease manifested itself in a form of generalized chronic catarrhal gingivitis and chronic generalized periodontitis of mild and moderate degrees.

<p><span>Isolated nasopharyngeal candidiasis in an immunocompetent host, has not been reported in literature. This is a case of a 48 year old lady with no comorbidities who presented with a mass in the nasopharynx mimicking nasopharyngeal malignancy. Endoscopic debridement and biopsy revealed necrotic tissue with fungal ball composed of filamentous hyphae suggestive of aspergillus and budding yeast form of Candida. A diagnosis of fungal nasopharyngitis was made and started on antifungal therapy for 6 weeks following which patient is relieved of symptoms.</span></p>
