A case report from Zhejiang, People's Republic of China, discusses a rare case of retroperitoneal lymph node tuberculosis complicated by intestinal obstruction. The patient, a 51-year-old man, presented with abdominal pain and fever, and imaging revealed enlarged retroperitoneal lymph nodes compressing the intestinal lumen. Ultrasound-guided percutaneous lymph node aspiration confirmed the presence of Mycobacterium tuberculosis, and the patient's symptoms improved with anti-tuberculosis treatment. The study emphasizes the importance of early diagnosis and histopathology in cases of retroperitoneal lymph node tuberculosis. [Extracted from the article]

A recent study conducted by researchers at the All India Institute of Medical Sciences (AIIMS) in New Delhi, India, focused on lymph node tuberculosis. The study found that while pulmonary tuberculosis is more common, nodal tuberculosis can present in isolation, particularly affecting cervical lymph nodes. Various imaging techniques, such as radiographs and ultrasound, are used for diagnosis and assessment. Computed tomography and magnetic resonance imaging are used to evaluate cases of thoracic and abdominal lymphadenopathy, with fluorodeoxyglucose-positron emission tomography and newer modalities like shear-wave elastography and contrast-enhanced ultrasound also discussed. This research provides valuable insights into the imaging features and recent advances in lymph node tuberculosis. [Extracted from the article]

A study conducted by the Hunan Institute for Tuberculosis Control in China investigated the clinical epidemiological and drug resistance characteristics of lymph node tuberculosis (LNTB) in Hunan Province. The study found that LNTB was more prevalent in younger individuals, while drug resistance was more common in older individuals. The researchers recommend further studies to understand the occurrence of drug resistance in LNTB and emphasize the importance of improving diagnoses and treatments to prevent the emergence of drug resistance. This information is valuable for researchers and healthcare professionals working on tuberculosis prevention and treatment. [Extracted from the article]

A recent study conducted at the Government Institute of Medical Sciences in Uttar Pradesh, India, focused on lymph node tuberculosis. The researchers highlighted the importance of considering extrapulmonary tuberculosis, particularly in regions where the disease is prevalent. They presented a rare case of a 28-year-old female with isolated cystic duct tubercular lymphadenitis, emphasizing the need for comprehensive clinical evaluation and diagnostic investigations to avoid misdiagnosis or delayed management. The study underscores the significance of maintaining a high index of suspicion for extrapulmonary tuberculosis and encourages healthcare practitioners to be vigilant when encountering unusual clinical presentations.

A study conducted by researchers at Cliniques Universitaires Saint Luc in Brussels, Belgium, aimed to compare lymph node tuberculosis and sarcoidosis to facilitate differential diagnosis and establish a predictive score for tuberculosis (TB). The study analyzed data from 441 patients, with 192 patients included in the final analysis. The researchers identified factors associated with each diagnosis and developed a risk score for TB based on weight loss, necrotic granuloma, normal serum lysozyme level, and hypergammaglobulinemia. The score showed excellent capacity to discriminate TB versus sarcoidosis, but further validation is needed in a multicentric prospective study. [Extracted from the article]

A study conducted at the Affiliated Hospital of North Sichuan Medical College in China examined the diagnostic value of tuberculosis-specific antigens ESAT-6 and CFP10 in lymph node tuberculosis. The researchers compared the effectiveness of acid-fast staining and immunohistochemical (IHC) staining in detecting these antigens. The results showed that IHC staining for ESAT-6 had a sensitivity of 87.5% and a specificity of 85.3%, while IHC staining for CFP10 had a sensitivity of 75.0% and a specificity of 89.7%. The study suggests that IHC staining may be a useful supplementary diagnostic tool for lymph node tuberculosis. [Extracted from the article]

A recent study conducted by the National Research and Innovation Agency (BRIN) has investigated the potential of microRNA (miRNA) as biomarkers for differentiating between active pulmonary tuberculosis (PTB), latent tuberculosis infection (LTBI), and lymph node tuberculosis (LNTB). The study found that the expression levels of miRNA hsa-miR-425-5p and hsa-miR-4523 were significantly different among the four groups (PTB, LTBI, LNTB, and healthy controls). The combination of both miRNAs showed the best performance in differentiating LNTB from LTBI. These findings provide new insights into the diagnosis of tuberculosis and highlight the significance of miRNA as an immunomarker for various diseases. [Extracted from the article]

A recent study conducted at the Pratima Institute of Medical Sciences in India examined cases of lymph node tuberculosis, a form of extra-pulmonary tuberculosis (EPTB). The study focused on peripheral lymph node tuberculosis, with a particular emphasis on cervical lymph nodes. The researchers evaluated the demographic and clinical characteristics of 24 cases of lymph node tuberculosis, finding that the majority of cases were female and from rural areas. Symptoms included swelling, fever, loss of appetite, and weight loss. The study concluded that lymph node tuberculosis should be considered as a potential diagnosis for peripheral lymph node swellings. [Extracted from the article]

According to news originating from the All India Institute of Medical Sciences (AIIMS) by NewsRx correspondents, research stated, "The paradoxical reaction (PR) is a transient worsening following tuberculosis treatment and it is not uncommon in lymph node tuberculosis (LNTB).
