Coronavirus disease 2019 (COVID-19) has penetrated our daily lives, leading us to a new normal era. The unexpected impact of COVID-19 has posed a unique challenge for the health care system, bringing innovation around the world. Considering the current pandemic pattern, comprehensive preparedness strategies of healthcare resources need to be implemented to prepare for a large resurgence of COVID-19 within a short time. With the unprecedented spread of the new pandemic and the impending influenza season, scientific evidence-based schemes need to be developed through cooperation, coordination, and solidarity. Based on the early experience with the current pandemic, this narrative interpretive review of qualitative studies suggests a 6-domain plan to establish a better health care system that is prepared to deal with the current and future public health crises. The 6 domains are medical institutions, medical workforce, medical equipment, COVID-19 surveillance, data and information application, and governance structure.

Tuberculosis (TB) is a common disease worldwide. However, nasal TB is quite rare, and the diagnosis of nasal TB requires a high index of suspicion. The most common symptoms of this unusual presentation are nasal obstruction and nasal discharge. We present a case of nasal TB with involvement of the hard palate presenting with a chronically progressive nasal deformity and ulceration of the hard palate. A biopsy confirmed the diagnosis, and medication for TB was started and the lesions resolved. When a patient presents with chronic ulcerative lesions that do not respond to antibiotic treatment, TB should be included in the differential diagnosis. Biopsy of the lesion can aid in the confirmation of the diagnosis.

We report a case of spontaneous bacterial peritonitis from Ochrobactrum anthropi. O. anthropi is recognized as an emerging pathogen in immunocompromised patients. In contrast to most previously described cases, the patient reported here had no indwelling catheter. To our knowledge, no case of O. anthropi spontaneous bacterial peritonitis has been reported in the medical literature until now.

BACKGROUND/AIMS: We evaluated the clinical features of ciprofloxacin-resistant Proteus mirabilis bacteremia and risk factors for ciprofloxacin resistance. METHODS: From October 2000 to July 2009, 37 patients with clinically significant P. mirabilis bacteremia were identified and data from patients with ciprofloxacin-resistant and ciprofloxacin-susceptible P. mirabilis bacteremia were compared. RESULTS: The most common underlying diseases were neurologic disease (37.8%) and solid tumors (29.7%). The most common site of infection was the urinary tract (35.1%). Ten of the 37 patients (27.0%) were infected with ciprofloxacin-resistant isolates, and univariate analysis revealed a significant relationship between ciprofloxacin-resistant P. mirabilis bacteremia and neurologic disease, recent operation, L-tube insertion, percutaneous tube use, and extended-spectrum beta-lactamase (ESBL) production (all p < 0.05). ESBL was detected in six of 10 (60%) ciprofloxacin-resistant isolates, while only three of 27 (11%) ciprofloxacin-susceptible isolates produced ESBL (p = 0.005). In a logistic regression analysis, ESBL production remained a significant factor associated with ciprofloxacin resistance, after adjusting for other variables. CONCLUSIONS: These data indicate a close association between ciprofloxacin resistance and ESBL-production in P. mirabilis bacteremia. This association is particularly troublesome because the therapeutic options for serious infections caused by ESBL-producing P. mirabilis are severely restricted.

Infective endocarditis usually involves cardiac valves and perivalvular tissue. Sometimes it can penetrate through the free wall of myocardium and form burrowing abscess, usually in patients with congenital heart diseases, such as ventricular septal defect. We experienced a case of mural endocarditis of right atrium in a patient without underlying cardiac diseases. A 55-year old man was admitted due to chest tightness, fever and dyspnea. Streptococcus intermedius grew in 3 pairs of blood culture tests and transesopha- phageal echocardiography revealed a 2 cm-sized vege-tation in the right atrial auricle. Lung ventilation and perfusion scans were checked due to aggravation of dyspnea, which showed pulmonary embolism with high probability. The vegetation penetrated through the free wall of the right atrial auricle and formed a mural abscess, which was removed by surgery and its wall defect repaired with bovine patch.

A mycotic aneurysm is a localized, irreversible arterial dilatation resulting from destruction of the vessel wall by infection. Pathogens causing mycotic aneurysms include Gram-positive and -negative bacteria, mycobacteria, and fungi. Klebsiella pneumoniae is a common pathogen causing urinary tract infections, nosocomial pneumonia, soft tissue infection, pyogenic liver abscesses, and endophthalmitis, while mycotic aneurysms caused by K. pneumoniae are rare. Recently, the number of cases of endogenous K. pneumoniae endophthalmitis associated with K. pneumoniae-induced pyogenic liver abscesses has increased in Southern Asia, but there have been no reports of K. pneumoniae mycotic aneurysms accompanied by endophthalmitis. Here, we report the case of a man who had a K. pneumoniae mycotic aneurysm accompanied by endophthalmitis and, ultimately, lost sight in both eyes. The early diagnosis of associated endophthalmitis requires a high index of suspicion by the physician.

Adenovirus is one of the major viral cause of upper respiratory tract infection. Life-threatening adenovirus pneumonia is often reported in neonates, young children and immunocompromised hosts. It can rarely occur in previously healthy adults. Because there is no report on adenovirus pneumonia in adult patients in Korea, we report two cases of adenovirus pneumonia which developed in adult women. Despite of intravenous antibiotics therapy, the respiratory distress worsened and mechanical ventilation was applied. Microbiological tests for bacteria or fungi were negative. A high-resolution chest computed tomography showed bilateral patch ground-glass opacification. Subsequently, open lung biopsy specimen revealed diffuse alveolar damage and adenovirus was documented with immunohistochemical stain. Treatment with cidofovir led to prompt clinical improvement in our cases.

Gemella species are opportunistic pathogens, which cause endocarditis, meningitis, musculoskeletal infections, or pulmonary infections. It is difficult to identify all strains of these species by a conventional culture system. Because 16S rRNA gene has the interspecific polymorphisms to differentiate the bacterial species, 16S rRNA gene sequence analysis could be used to identify these pathogens. To determine the molecular types of two unidentified Gram-positive cocci from two patients with infective endocarditis, PCR amplification and DNA sequencing of the 16S rRNA gene were performed. These sequences of the PCR product were compared with known 16S rRNA gene sequences using GenBank BLAST search. The 16S rRNA gene sequences of two isolates showed > 99% nucleotide similarities with those of Gemella morbillorum (GenBank accession number L14327). Phylogenetic analysis also indicated the close relatedness between these isolates and G. morbillorum.

Non-typhoidal Salmonella species are important foodborne pathogens that can cause gastroenteritis, bacteremia, and subsequent focal infections. Non-typhoidal salmonellosis is problematic, particularly in immunocompromised hosts. Any anatomical site can be affected by this pathogen via hematogenous seeding and may develop local infections. However, cervical lymphadenitis caused by non-typhoidal Salmonella species is rarely reported. Herein, we have reported a case of cervical lymphadenitis caused by group D non-typhoidal Salmonella associated with lymphoma.
