Scrofuloderma: A diagnostic dilemma in primary care

Md Rifin S, Shalihin MSE, Mat Jidin M

Med J Malaysia, 2021 05;76(3):419-421.
PMID: 34031344

A 35-year-old lady presented at the Klinik Kesihatan Bandar 32 Bera, Pahang with a one-month history of multiple cervical swelling and ulcers over her neck area. The lesions began as papules and later progressively developed into nodules and pustules. She also had low grade fever associated with weight loss for one month duration. Chest xray revealed normal findings and sputum direct smear for acid fast bacilli was noted to be negative. Histopathologic finding of skin biopsy revealed central epidermal necrosis surrounded by granulomatous tissue forming an abscess and histiocyte infiltrates, confirming the diagnosis of Scrofuloderma. In view of the report of the fine needle aspiration cytology (FNAC) of the cervical lymph nodes suggestive for tuberculous lymphadenitis, the patient was given anti-tuberculosis therapy. Fortunately, six months later, the ulcers began to solve and heal gradually.
Idiopathic hyperprolactinemia - A challenge for primary care

Hyperprolactinemia is a condition of elevated serum prolactin, which usually occurs in women as compared to men. Most patients present to primary care clinics with a history of galactorrhoea, oligomenorrhea, amenorrhoea or infertility. Literature search reveals that there were few idiopathic causes of hyperprolactinemia, which resolved by itself without specific pharmacological or surgical treatment. This case is of a 39-year-old woman presented with amenorrhea for four months after Implanon removal and concomitantly noted to have galactorrhoea for four years without any medical attention. The condition persisted after cessation of breastfeeding. After undergoing several investigations including imaging studies, the underlying cause of hyperprolactinemia was noted to be idiopathic. Due to the unclear cause of its aetiology, this case caused various challenges to the primary care. Exhaustive physiological and pathological causes of hyperprolactinemia have been ruled out. Nevertheless, with adequate treatment, she gained her normal menstrual and resolved galactorrhoea symptoms.
The clinical implications of Porphyromonas gingivalis and its detection methods - a systematic review

INTRODUCTION: Mounting evidence has shown the significant correlation between periodontitis and the development of other comorbidities, such as cardiovascular disease due to periodontopathogenic bacterial migration and colonisation. As the main etiologic agent of periodontitis, the role of Porphyromonas gingivalis (P. gingivalis) has been widely explored as the main culprit and its early detection is crucial to control the exacerbation of diseases. This review aims to identify and summarise all clinical diseases that potentially developed due to the presence of P. gingivalis and discover all its detection methods that have been developed.
MATERIALS AND METHODS: Full-text articles of case report, case control, cohort and cross-sectional studies that were published from 1st January 2012 until 30th June 2022, were searched using PubMed, CINAHL and Scopus. Periodontal related diseases were excluded in this review due to its wellknown associated disease with P. gingivalis. A comparison studies of detection methods were also excluded in this review.
RESULTS: Out of 612 articles that were screened, only 106 met the eligibility criteria to be selected for further review. Risk of bias was performed using FEAT principles and reviewers' discussion. A total of 21 final articles that were reviewed showed significant correlation with P. gingivalis and were classified into several clinical domains. Twelve out of 13 detection methods showed high sensitivity and specificity with short duration analysis.
CONCLUSION: Due to asymptomatic periodontal disease and the high prevalence of P. gingivalis-associated clinical diseases, this review suggests the need for oral public health awareness and early screening for the bacterium detection especially among elderly groups to maintain their quality of life.
Streptococcus gallolyticus infection: A neglected marker for colorectal cancer?

Bin Ismail CMKH, Bin Mohammad Aidid E, Binti Hamzah HA, Bin Shalihin MSE, Bin Md Nor A

Arab J Gastroenterol, 2023 Aug;24(3):163-167.

BACKGROUND AND STUDY AIMS: Colorectal cancer (CRC) is the second most common cancer in Malaysia and mostly detected at advanced stages due to lack of awareness of CRC symptoms and signs. CRC pathogenesis is multifactorial, and there is ambiguous evidence on association of Streptococcus gallolyticus infection with CRC that needs further attention. Thus, a case-control study was conducted to determine whether S. gallolyticus infection is a predictor for CRC occurrence among patients attending Sultan Ahmad Shah Medical Centre@IIUM (SASMEC@IIUM).
PATIENTS AND METHODS: A total of 33 stool samples from patients diagnosed with CRC and 80 from patients without CRC attending surgical clinic of SASMEC@IIUM were collected and analyzed with iFOBT test and PCR assay to detect S. gallolyticus.
RESULTS: In this study, the proportion of S. gallolyticus infection was higher among patients with CRC (48.5%) compared with the control group (20%). Univariate analysis shows that occult blood in stool, S. gallolyticus infection and family history were significantly associated with the development of CRC (P
Risk of colorectal cancer due to Streptococcus gallolyticus: a systematic review

INTRODUCTION: World Health Organization (2019) has declared colorectal cancer (CRC) as the second most common cancer in females and third in males, where the incidence seems to rise year by year. One of the very few potential pathogens specifically associated with malignant colonic diseases is Streptococcus gallolyticus (Sg). Sg is a part of the intestinal flora which formerly known as biotype I of Streptococcus bovis, belongs to Group D streptococci. Owing to only a few researches done in determining evidence to support Sg as a determinant of CRC, a systematic review is constructed.
MATERIALS AND METHODS: Full-text articles on case-control and cohort studies published from 1st January 2010 to 1st October 2020 were searched using Google Scholar, PubMed and JSTOR. People of all age groups and Sg bacteraemia or colonisation were the type of participant and exposure used for the search strategy, respectively. Data collection was done by three reviewers and checked by two reviewers for discrepancies. All the papers were critically appraised using the STROBE statement. Qualitative synthesis was done by descriptive comparison, distribution of Sg according to stage comparison, method used for Sg detection comparison and risk of bias comparison.
RESULT: Seven out of 11 articles that fulfil the eligibility criteria were selected. Four papers have low overall risk of bias due to low confounding or selection bias. Sg is found to be a risk factor for CRC from three papers studied, whereas the other four papers did not include the strength of association. Only two papers studied the association between the distribution of Sg and stages of CRC, where the results were contradictory from each other, making it to be inconclusive. The most common method used for Sg detection is a culturing technique, followed by molecular and biochemical techniques.
CONCLUSION: There is insufficient evidence to prove the association between Sg bacteraemia as the risk factor for CRC as well as the association between the Sg distribution and stages of CRC. Culturing technique is the most common method used for the detection of bacteria, but it requires subsequent investigations to confirm the presence of Sg. Thus, it is recommended that more studies need to be done using strong statistical analysis to control for most of the confounders with comprehensive explanation and use of more methods in the detection of Sg.
