Sphenoethmoid sinusitis in a child resulting in a disastrous intracranial sequela

PMID: 23288800

Localized sphenoethmoid sinusitis in children is a rare occurrence. It is usually overlooked because of the misconception that the sinuses are not developed. We describe a case of localized acute sphenoid and right posterior ethmoid sinusitis that presented as right frontobasal subdural empyema and multiple deep cerebral abscesses. Morbidity from subdural empyema in children is high. Early diagnosis and treatment based on recognition that the etiology might involve the paranasal sinuses affects the overall prognosis.

Fulltext The association of Streptococcus bovis/gallolyticus with colorectal tumors: the nature and the underlying mechanisms of its etiological role

Streptococcus bovis (S. bovis) bacteria are associated with colorectal cancer and adenoma. S. bovis is currently named S. gallolyticus. 25 to 80% of patients with S. bovis/gallolyticus bacteremia have concomitant colorectal tumors. Colonic neoplasia may arise years after the presentation of bacteremia or infectious endocarditis of S. bovis/gallolyticus. The presence of S. bovis/gallolyticus bacteremia and/or endocarditis is also related to the presence of villous or tubular-villous adenomas in the large intestine. In addition, serological relationship of S. gallolyticus with colorectal tumors and direct colonization of S. gallolyticus in tissues of colorectal tumors were found. However, this association is still under controversy and has long been underestimated. Moreover, the etiological versus non-etiological nature of this associationis not settled yet. Therefore, by covering the most of up to date studies, this review attempts to clarify the nature and the core of S. bovis/gallolyicus association with colorectal tumors and analyze the possible underlying mechanisms.

Streptococcus suis is a Gram-positive cocci bacterium that are found mainly in pigs and can be transmitted to human through pigs or pork exposure. The disease is mainly found among occupations involving swine contact in western countries whereas in Asia the disease is usually contracted through raw pork consumption. In this case report, we present a case of a middle-aged Thai man who acquired the infection from raw pork consumption. He presented with endogenous endophthalmitis with infective spondylodiscitis, sepsis and meningitis and later developed blindness of the right eye and permanent bilateral hearing loss disseminated from S. suis infection. Our report suggests that S. suis infection be considered as a causative factor in patient presenting with established clinical symptoms and predisposing factors. Cultural habit of eating raw pork should be taken into account especially in Asian countries.

We report a case of a 46-year-old Malay woman with underlying hypothyroidism post thyroidectomy who presented with worsening breathlessness, orthopnoea, productive cough and left-sided pleuritic chest pain of 3 days duration. Chest X-ray on admission showed left-sided massive hydropneumothorax. Pleural tapping revealed empyema. A chest tube was inserted immediately. The culture of pleural fluid grew Streptococcus constellatus The patient was treated with antibiotics for a total of 6 weeks and underwent open thoracotomy and decortication during admission. Subsequently, her lung condition improved and there was no evidence of recurrence during follow-up.

Fulltext Intracranial bleeding (ICB) as a catastrophic complication of Streptococcus gordonii infective endocarditis (IE) in an immunocompetent patient

Pairan MS, Mohammad N, Abdul Halim S, Wan Ghazali WS

PMID: 30206067 DOI: 10.1136/bcr-2018-225265

We present an interesting case of late-onset intracranial bleeding (ICB) as a complication of Streptococcus gordonii causing infective endocarditis. A previously healthy young woman was diagnosed with infective endocarditis. While she was already on treatment for 2 weeks, she had developed seizures with a localising neurological sign. An urgent non-contrasted CT brain showed massive left frontoparietal intraparenchymal bleeding. Although CT angiogram showed no evidence of active bleeding or contrast blush, massive ICB secondary to vascular complication of infective endocarditis was very likely. An urgent decompressive craniectomy with clot evacuation was done immediately to release the mass effect. She completed total 6 weeks of antibiotics and had postoperative uneventful hospital stay despite having a permanent global aphasia as a sequel of the ICB.

PMID: 21338230

Colorectal cancer (CRC) is the second most common cause of cancer mortality among men and women worldwide; the risk of its occurrence has been shown to be increased by chronic bacterial infections. A case control study was therefore carried out at Hospital Universiti Sains Malaysia (HUSM) to determine the incidence of colorectal cancer associated with S. bovis infection. A total of 166 stool specimens were collected from diseased patients and healthy individuals and S. bovis isolates were identified. Suspected colon tumor and cancer cases were diagnosed and confirmed. It was found that overall prevalence of S. bovis was 41 (24.7%) out of 166 cases studied. Some 41(48.6%) of these S. bovis isolates was found in patients with colonic polyps, adenocarcinomas, inflammatory bowel disease (IBD) and chronic gastrointestinal tract (GIT). It was also found that colorectal cancer incidence was 24.7%, adenocarinomas accounting for 51% with the highest incidence in the sigmoid part of the colon. Among the IBD and chronic GIT cases, ulcerative colitis featured in the majority of cases (41.4%). In conclusion, there is a high incidence of colorectal cancer associated with S. bovis.

Adult varicella zoster infection complicated with streptococcal retrosternal abscess

Yap FBB, Kiung ST

South. Med. J., 2009 Jun;102(6):653-5.

PMID: 19434036 DOI: 10.1097/SMJ.0b013e3181a49a71

A 43-year-old lady with type 2 diabetes mellitus and bronchial asthma presented with varicella zoster infection, dyspnea, and neck fullness. An urgent computed tomography scan revealed a mediastinal abscess with superior vena cava thrombus. Blood, mediastinal pus, and swab from a vesiculopustule on the neck cultured group A beta hemolytic Streptococcus. She recovered with a combination of broad spectrum antimicrobials, antivirals, and surgical drainage. This case illustrates the rare occurrence of mediastinal abscess and acute superior vena cava obstruction caused by group A beta hemolytic Streptococcus complicating adult varicella zoster.

Fulltext A risk scoring system for predicting Streptococcus suis hearing loss: A 13-year retrospective cohort study

Rayanakorn A, Katip W, Goh BH, Oberdorfer P, Lee LH

PLoS One, 2020;15(2):e0228488.

PMID: 32017787 DOI: 10.1371/journal.pone.0228488

BACKGROUND: Streptococcus suis (S.suis) is an emerging zoonosis disease with a high prevalence in Southeast Asia. There are over 1,500 cases reported globally in which majority of cases are from Thailand followed by Vietnam. The disease leads to meningitis in human with sensorineural hearing loss (SNHL) as the most common complication suffered by the patients. Early diagnosis and treatment is important to prevent severe neurological complication. In this study, we aim to develop an easy-to-use risk score to promote early diagnosis and detection of S.suis in patients who potentially develop hearing loss.

METHODS: Data from a retrospective review of 13-year S.suis patient records in a tertiary hospital in Chiang Mai, Northern, Thailand was obtained. Univariate and multivariate logistic regressions were employed to develop a predictive model. The clinical risk score was constructed from the coefficients of significant predictors. Area under the receiver operator characteristic curve (AuROC) was identified to verify the model discriminative performance. Bootstrap technique with 1000-fold bootstrapping was used for internal validation.

KEY RESULTS: Among 133 patients, the incidence of hearing loss was 31.6% (n = 42). Significant predictors for S. suis hearing loss were meningitis, raw pork consumption, and vertigo. The predictive score ranged from 0-4 and correctly classified 81.95% patients as being at risk of S.suis hearing loss. The model showed good power of prediction (AuROC: 0.859; 95%CI 0.785-0.933) and calibration (AuROC: 0.860; 95%CI 0.716-0.953).

CONCLUSIONS: To our best knowledge, this is the first risk scoring system development for S.suis hearing loss. We identified meningitis, raw pork consumption and vertigo as the main risk factors of S.suis hearing loss. Future studies are needed to optimize the developed scoring system and investigate its external validity before recommendation for use in clinical practice.
