Common variable immune deficiency (CVID) is the most common primary immune deficiency, which is manifested as chronic recurrent respiratory infections and hypoglobulinemia. CVID usually presents in the second or third decade of life. A 33-year-old woman was admitted with recurrent pneumococcal pneumonia with bacteremia and had very low levels of serum immunoglobulin G, M and A. This case emphasized a high index of suspiciousness for diagnosis of CVID in a mid-adulthood patient presenting with recurrent pneumonia with hypoglobulinemia.

Mycobacterium massiliense is newly identified rapid-growing nontuberculous mycobacterium, but there are no reports of this mycobacterium species being the cause of human illness. We describe one case of Mycobacterium massiliense infection presenting as antibiotic-resistant acute pneumonia that resulted in surgical treatment.

Leiomyosarcoma of the oral cavity is a very rare tumor that is associated with aggressive clinical behavior and low survival. In this paper, we report a case of leiomyosarcoma presenting with a gingival exophytic mass that rapidly grew, causing facial asymmetry within 16 days, in a 9-year-old boy. After an excisional biopsy, microscopy revealed a spindle cell neoplasm that, on immunohistochemistry analysis, demonstrated reactivity for SMA. This established the diagnosis of leiomyosarcoma; subsequently, a marginal mandibulectomy and supraomohyoid neck dissection were performed.

Streptococcus suis causes meningitis and sepsis in pigs, but human infection has increased over the past few years in those who are exposed to pigs or raw pork. Most cases have occurred in Southeast Asia, but only two cases have been reported in South Korea, presenting with arthritis and meningitis. Here, we report a rare case of S. suis infection, a 60-year-old sailor, who visited the emergency room presenting septicemia, pneumonia with empyema and meningitis, showed full recovery; however, neurologic sequale of severe cognitive dysfunction was present after the usage of antibiotics and percutaneous drainage. S. suis was isolated from blood and pleural fluid and the strain was susceptible to penicillin and vancomycin. Increased awareness of S. suis infection and prevention are warranted.

Tuberculosis of the retropharynx is extremely rare. The diagnosis is frequently delayed because of its anatomical location and atypical symptom. It would be crucial to consider tuberculosis infection as a possible source of abscess and should be mindful about the tests to diagnose it. We experienced a 23-year-old man with retropharyngeal abscess caused by tuberculosis presenting hypernasality and hoarseness in the throat. In this article, we reviewed the etiology, diagnosis, and treatment of this case, with a review of literatures.

Hamangiopericytoma, first described by Stout & Murray in 1942, is a rare vascular tumor composed of spindle-shaped or rounded cells proliferating around endothelial lined capillaries. These proliferating cells were belived to arise from the pericytes of Zimmerman. Histologically, this tumor demonstrates great variability and clinical course cannot be predicted from the histological appearance. Head and Neck hemangiopericytoma appears to have a lower grade malignancy with frequent local recurrency and metastasis, therefore, aggressive surgical therapy should be the treatment of choice. We experienced a case of hemangiopericytoma occurred in the right skull base at submastoideal and suboccipital area presenting as neck mass in upper occipital triangle in a 42 years old female patient and we report it with a review of literatures.

A lactic acid bacterium presenting antimicrobial activity against a Lactobacillus acidophilus strain used for eradication of acid inhibition was isolated from a natural cheese. The 16S rRNA gene sequence of the isolate best matched with a strain of L. rhamnosus and was designated L. rhamnosus CJNU 0519. The antimicrobial activity of the partially purified bacteriocin of CJNU 0519 was abolished when treated with a protease, indicating the protein nature of the bacteriocin. The partially purified bacteriocin (rhamnocin 519) displayed a narrow antimicrobial activity against L. acidophilus, Listeria monocytogenes, and Staphylococcus aureus among several tested bacterial and yeast strains. Rhamnocin 519 in particular showed strong bactericidal action against L. monocytogenes.

In recent years, the knowledge about bifidobacteria has considerably evolved thanks to recent progress in molecular biology. The analysis of the whole genome sequences of 48 taxa of bifidobacteria offers new perspectives for their classification, especially to set up limit between two species. Indeed, several species are presenting a high homology and should be reclassified. On the other hand, some subspecies are presenting a low homology and should therefore be reclassified into different species. In addition, a better knowledge of the genome of bifidobacteria allows a better understanding of the mechanisms involved in complex carbohydrate metabolism. The genome of some species of bifidobacteria from human but also from animal origin demonstrates high presence in genes involved in the metabolism of complex oligosaccharides. Those species should be further tested to confirm their potential to metabolize complex oligosaccharides in vitro and in vivo.
