Thoracic Tuberculosis

Background: Chest ultrasound (CUS) has been shown to be a sensitive and specific imaging modality for pneumothorax, pneumonia, and pleural effusions. However, the role of chest ultrasound in the diagnosis of thoracic tuberculosis (TB) is uncertain. We performed a systematic search in the medical literature to better define the potential role and value of chest ultrasound in diagnosing thoracic tuberculosis. Aim: To describe existing literature with regard to the diagnostic value of chest ultrasound in thoracic tuberculosis. Methods: MEDLINE, EMBASE, and Scopus databases were searched for relevant articles. We included studies that used chest ultrasound for the diagnosis or management of any form of thoracic tuberculosis, including pulmonary, pleural, mediastinal, and military forms. Results: We identified five main fields of chest ultrasound application: (1) Detection, characterization, and quantification of TB; (2) detection of residual pleural thickening after evacuation; (3) chest ultrasound-guided needle biopsy; (4) identification of pathologic mediastinal lymph nodes in children; and (5) identification of parenchymal ultrasound patterns. Effusion was also detected, in early stages, with signs of organization in 24–100% of patients. A low to moderate (10–23%), false negative rate was reported for chest ultrasound-guided needle biopsy. CUS was able to identify mediastinal lymph nodes in as many as 67% of patients with negative chest radiography. Conclusions: Very few studies with important methodological limitations analyze the role of chest ultrasound in the diagnosis of TB. The scarce available data suggests potential targets of future diagnostic or feasibility trials, such as the detection of tuberculosis–related pleural effusion, residual pleural thickening, lymphadenopathy, TB parenchymal patterns, or the use of CUS in biopsy guidance.

Abstract Background Aim of the study is to evaluate the role of ultrasound guided fine needle aspiration cytology (FNAC) in the restaging of node positive breast cancer after preoperative systemic therapy (PST). Methods From January 2016 – October 2020 106 node positive stage IIA-IIIC breast cancer cases undergoing PST were included in the study. 18 (17 %) were carriers of pathogenic variant in BRCA1/2. After PST restaging of axilla was performed with ultrasound and FNAC of the marked and/or the most suspicious axillary node. In 72/106 cases axilla conserving surgery and in 34/106 cases axillary lymph node dissection (ALND) was performed. Results False Positive Rate (FPR) of FNAC after PST in whole cohort and BRCA1/2 positive subgroup is 8 and 0 % and False Negative Rate (FNR) – 43 and 18 % respectively. Overall Sensitivity − 55 %, specificity- 93 %, accuracy 70 %. Conclusion FNAC after PST has low FPR and is useful to predict residual axillary disease and to streamline surgical decision making regarding ALND both in BRCA1/2 positive and negative subgroups. FNR is high in overall cohort and FNAC alone are not able to predict ypCR and omission of further axillary surgery. However, FNAC performance in BRCA1/2 positive subgroup is more promising and further research with larger number of cases is necessary to confirm the results.

Background Hysterosalpingography (HSG) is a useful screening test for the evaluation of female infertility. Laparoscopy has proven role in routine infertility work up but role of hysteroscopy in an infertile patient with normal HSG for additional information is a subject of debate. Hysteroscopy permits direct visualization of the cervical canal and the uterine cavity and thereby helping in the evaluation of shape, and cavitary lesion.Objective To detect uterine abnormalities in infertile women by various approaches i.e. HSG and hysteroscopy and evaluating the role of combining hysteroscopy with laparoscopy for the evaluation of tubo-uterine factor for primary infertility.Method One twenty eight infertile women were evaluated and HSG was performed as a basic test for evaluation of tubes and uterine cavity. Women were subjected to combined laparoscopic and hysteroscopic examination on evidence of HSG abnormalities. In absence of any HSG abnormality, women were subjected to ovulation induction for three to six months and if they did not conceive during this period they were undertaken for combined laparo-hysteroscopic evaluation.Result The positive predictive value of HSG for detecting the intrauterine abnormalities was 70% among 126 patients where the hysteroscopy could be performed successfully. The diagnostic accuracy of HSG for intrauterine abnormalities revealed false negative rate of 12.96%. The most frequent pathologies encountered by laparoscopy were tubal and/or peritoneal and were found in 68% (87/128) of women. Total 64.06% infertile women had some abnormality on laparoscopy. This detection rate has been increased from 64.06% to 71.86% on including the concomitant hysteroscopy.Conclusion HSG is a good diagnostic modality to detect uterine as well as tubal abnormalities in infertile patient. HSG and hysteroscopy are complementary to each other and whenever the patient is undertaken for diagnostic laparoscopy for the infertility, hysteroscopy should be combined to improve the detection rate of abnormalities especially in communities where there is enormous risk of pelvic infection.
