ABSTRACT

Objective: Enlargement of the adrenal glands and variable adrenocortical function have been reported in patients with pulmonary tuberculosis and, in a few studies, in patients with extrapulmonary tuberculosis (EPTB). However, none of the studies have evaluated the course of the adrenal morphology in these patients. Subjects and methods: Prospective study including 37 patients with EPTB and 37 healthy age- and sex-matched controls. The adrenal function was evaluated by measurement of cortisol levels at baseline and after stimulation with ACTH (Acton Prolongatum) before and 6 months after antituberculosis treatment. The size of both adrenal glands was evaluated using 64-slice computed tomography (CT) scanning before and 6 months after treatment. The findings were compared with those in a group of healthy matched controls. Results: Clinical and biochemical parameters were comparable between groups. The mean baseline serum cortisol level was significantly lower in the EPTB group (397.1 ± 184.9 nmol/L) compared with the control group (696.3 ± 101.8 nmol/L). Compared with controls, patients with EPTB had significantly lower mean cortisol levels at baseline and 1 hour after ACTH, both before (397 ± 184.9 nmol/L and 750.7 ± 176.8 nmol/L, respectively) and after (529.7 ± 100.4 nmol/L and 1017.2 ± 119.7 nmol/L, respectively) antituberculosis treatment. Both the length and thickness of the right and left adrenal glands were greater in patients with EPTB than in controls but became comparable to those in controls after treatment completion. Conclusion: Patients with EPTB have an enlarged adrenal size and low baseline and stimulated serum cortisol levels. After treatment completion, cortisol levels increased significantly, and the adrenal size normalized in these patients.

ABSTRACT

Introduction: Sheehan syndrome is a common cause of hypopituitarism in developing countries. Among risk factors, in addition to post-partum haemorrhage, a smaller sellar volume is also believed to predispose to pituitary necrosis. Some earlier studies have reported smaller sellar volume in these patients but involved a small number of patients and lacked matched controls. The main of the present study was to study the sellar volume in a large cohort of patients with Sheehan syndrome and compare it with age- and parity-matched controls. Methods: Fifty women with Sheehan syndrome and an equal number of age- and parity-matched controls were studied. Baseline investigations, relevant hormonal assay, and MRI of pituitary were studied in all. Results: Sellar volume was significantly lower in patients with Sheehan syndrome (334.50 ± 129.08 mm3 in patients as against 456.64 ± 169.25 mm3 in controls, P = 0.000). Far more women with Sheehan syndrome than controls had decreased sellar volume (40% vs. 12%). Conclusions: Patients with Sheehan syndrome have a smaller sellar volume that may be a non-modifiable risk factor for the development of post-partum pituitary necrosis.

ABSTRACT

OBJECTIVE: Polycystic ovary syndrome (PCOS) is a complex disorder with diverse metabolic implications. Diagnosis typically relies on oligo-amenorrhoea (OA), hyperandrogenism (HA), and polycystic ovarian morphology (PCOM). However, the role of polymenorrhoea in PCOS remains understudied. Additionally, limited information exists regarding metabolic disturbances in women with partial PCOS phenotypes that do not meet diagnostic criteria. This extensive database aims to provide substantial evidence on the metabolic implications of polymenorrhoea and partial PCOS phenotypes. DESIGN: Prospective observational study. PATIENTS AND MEASUREMENTS: In this single-centre study, 6463 women with PCOS-like characteristics and 3142 age-matched healthy women were included. The study compared clinical (anthropometry, modified Ferriman Gallwey [mFG] score), hormonal (serum testosterone), and metabolic (plasma glucose, serum lipids, insulin) characteristics between women diagnosed with PCOS, those with partial PCOS phenotypes, and the healthy control group RESULTS: In all, 5174 women met Rotterdam criteria for PCOS diagnosis, while 737 were classified as Pre-PCOS, including HA (n = 538), OA (n = 121), or PCOM (n = 78). Common clinical features included oligomenorrhoea (75.5%), hirsutism (82.9%), obesity (27.2%), hypertension (1.6%), metabolic syndrome (19.6%), and diabetes mellitus (5.6%). Women diagnosed with PCOS, HA only, and OA only exhibited higher average body mass index, plasma glucose levels (both fasting and 2 h after the oral glucose tolerance test), and lipid fractions in comparison to those with PCOM and the healthy controls. However, indices of insulin resistance were similar among women with PCOS, HA, PCOM, and OA, albeit higher than in the healthy controls. The polymenorrhoea subgroup (5.9%) had lower BMI and serum testosterone, but similar mFG score, plasma glucose, insulin, and lipid levels as the oligomenorrhoea subgroup. CONCLUSION: The metabolic disturbances observed in Pre-PCOS women highlight the need to reassess diagnostic criteria. Including the polymenorrhoea subcategory in PCOS criteria is recommended due to similar metabolic dysfunctions as the oligomenorrhoea group.

ABSTRACT

Background Pneumothorax is the most common complication of computed tomography (CT)-guided lung biopsy. The asymptomatic rate ranges from 17.5 to 72%. The symptomatic rate requiring chest tube insertion is 6 to 18%. Aims This article studies the role of management of postbiopsy pneumothoraces by needle aspiration and pigtail catheter insertion. Methods This was a prospective observational study conducted over 2 years. Postbiopsy and prior to withdrawing the coaxial cannula a CT data set was obtained to detect and quantify pneumothoraces as mild, moderate, and severe. In all asymptomatic cases of mild pneumothorax simple observation was done. In all asymptomatic cases of moderate pneumothorax, immediate needle aspiration was performed. In all symptomatic cases, cases with severe pneumothorax, and cases with progressively enlarging pneumothorax small caliber 6 to 8F pigtail catheters were inserted. Results Ninety-one cases had mild pneumothorax, 42 had moderate pneumothorax, and 18 had severe pneumothorax. In the 91 patients of mild pneumothorax only 1 (1%) patient showed increase in size of pneumothorax on follow-up requiring catheter insertion. In the 42 cases of moderate pneumothorax, which were managed by simple aspiration of pneumothorax, 4 (9.5%) cases showed increase in size of pneumothorax on follow-up. A total 23 cases required pigtail catheter insertion in our study. These constituted 15.2% of pneumothorax cases. The mean duration of catheterization in our study was 3.74 ± 1.09 days. Conclusion Majority of pneumothoraces are benign and do not require any intervention, just observation. Manual aspiration is an effective way of treating moderate pneumothoraces with success rate of 90%, thereby reducing the number of cases requiring catheter insertion; however, close observation is required as few cases may progress to severe pneumothorax and require pigtail insertion. Only a small percentage of biopsy cases (6.4%) require catheter insertion which is a safe and effective treatment.

ABSTRACT

Visceral artery pseudoaneurysms are potentially lethal lesions and tend to rupture in a high proportion of cases, thereby warranting an immediate and active intervention. We present our experience of splanchnic visceral artery pseudoaneurysms in a university hospital over a 5-year time interval with emphasis on etiology, clinical presentation, management (endovascular/surgical), and final outcome. This was a retrospective study in which we searched our image database for pseudoaneurysms of visceral arteries over a period of 5 years. The clinical and operative details were retrieved from the medical record section of our hospital. The lesions were analyzed for the vessel of origin, size, etiology, clinical features, mode of treatment, and outcome. Twenty-seven patients with pseudoaneurysms were encountered. Pancreatitis (8) was the most common cause, followed by previous surgery (7) and trauma (6). Fifteen were managed by the interventional radiology (IR) team, 6 by surgery, and in 6 no intervention was done. Technical and clinical success was achieved in all patients in the IR group with few minor complications. Surgery and no intervention carry a high mortality in such a setting (66 and 50%, respectively). Visceral pseudoaneurysms are potentially fatal lesions, commonly encountered after trauma, pancreatitis, surgeries, and interventional procedures. These lesions are easily salvageable by minimally invasive interventional techniques (endovascular embolotherapy), and surgeries carry a lot of morbidity and mortality in such cases and a prolonged hospital stay.

ABSTRACT

BACKGROUND: This prospective study was aimed at comparing phase contrast cardiac magnetic resonance imaging (PC-CMR) with 2D transoesophageal echocardiography (TEE) for determining potential candidature for transcatheter closure in ostium secundum ASD (OS-ASD) patients. We included consecutive adult patients with OS-ASD for the evaluation of feasibility for transcatheter closure using 2D-TEE and PC-CMR over a period of 2 years. Patients who fulfilled the conventional criteria for transcatheter closure, i.e. maximum ASD diameter ≤ 34 mm, adequate rims (≥ 5 mm, except for anterosuperior rim), and normal pulmonary venous drainage on both imaging modalities, were taken for device closure. In patients where there was discrepancy in the measurements of ASD diameter or rim size, making them eligible for device closure on one imaging modality and ineligible on the other hand, provisional device closure was attempted. All patients who underwent transcatheter closure were followed up to 6 months to rule out any complications. RESULTS: A total of 58 patients (mean age 35.93 ± 10.59 years) were enrolled in the study. Overall, there was significant positive correlation between 2D-TEE and CMR measurements of maximal ASD diameter and rim size (p < 0.001). However, TEE significantly underestimated maximal ASD diameter and posteroinferior rim size in comparison with CMR (p = 0.013 and p = 0.023, respectively). 46 (79.3%) patients were suitable for transcatheter closure on CMR, while 44 (75.9%) were eligible on TEE. Transcatheter closure was attempted in 48 patients based on imaging findings and was successful in 46 (95.8%) patients. Device closure was unsuccessful in 2 patients with defect size < 34 mm on TEE but > 34 mm on CMR. Among 7 patients with deficient posteroinferior rim on TEE, 5 had sufficient rim on CMR and underwent successful transcatheter closure. CMR detected anomalous pulmonary venous drainage in one patient which was missed on TEE, hence excluding the patient from transcatheter closure. Mean device size was 28.3 ± 7.4 mm and correlated more strongly with the defect dimensions on PC-CMR (r = 0.85, p < 0.001) compared to TEE (r = 0.71, p = 0.02). CONCLUSIONS: PC-CMR may to be superior to 2D-TEE for the preprocedural planning and feasibility assessment for transcatheter closure in adult patients with ostium secundum ASD.

ABSTRACT

BACKGROUND: Gastric cancer is the fifth most common cancer in the world. Preoperative staging of gastric cancer has assumed pivotal role in deciding appropriate management of gastric cancer with multi-detector computed tomography (MDCT) using hydro- and gaseous distension of stomach superseding endoscopic ultrasound in tumor (T) and nodal (N) staging. We undertook this study to evaluate the diagnostic accuracy of MDCT in the T and N staging of gastric cancer with an attempt to differentiate between early and advanced gastric carcinomas. METHODS: A total of 160 patients with endoscopically diagnosed and biopsy-proven gastric cancer were subjected to MDCT after adequate gaseous and hydro-distention of stomach. Multi-planar reformatted (MPR) as well as virtual gastroscopy images were also obtained. Gastric lesions were categorized into T1 to T4 stages with N staging from N0 to N3. Preoperative CT findings were correlated with histopathological findings. RESULTS: Overall diagnostic accuracy of T staging in our study was 82.5% (132/160) with an accuracy of 75% (120/160) for N staging. The diagnostic accuracy of CT for early gastric carcinoma in our study was 93.75% with high specificity of 96% but low sensitivity of 66.7%. CONCLUSION: MDCT using gaseous and hydro-distension of stomach is an excellent modality for near accurate preoperative T staging of gastric cancer. However, CT has a limited role in the N staging of gastric cancer. This study also suggested that the combined use of virtual gastroscopy and MPR images helps in better detection of early gastric cancers.

ABSTRACT

PURPOSE: To report the spectrum of chest computed tomographic (CT) imaging findings in coronavirus disease-19 (COVID-19) infected Indian patients. METHODS: This was a prospective descriptive study comprising 147 consecutive reverse transcriptase polymerase chain reaction (RT-PCR) positive patients who underwent CT chest. Prevalence, distribution, extent and type of abnormal lung findings were recorded. RESULTS: Among the total study cohort of 147 patients, 104 (70.7 %) were males and 43 (29.3 %) were females with mean age of 40.9 ±â€¯17.2 years (range 24-71 years). We observed lung parenchymal abnormalities in 51 (34.7 %) cases whereas 96 (65.3 %) RT-PCR positive cases had a normal chest CT. Only 12.2 % of the patients were dyspneic, 6.1 % had desaturation, 7.4 % had increased respiratory rate and 10.9 % had comorbidities. Among the patients with abnormal CT findings bilateral 39/51 (76.5 %), multilobar (88.2 %) lung involvement with a predominant peripheral and posterior distribution was commonly observed. With regards to the type of opacity, ground glass opacity (GGO) was the dominant abnormality found in all 51 (100 %) cases. Pure GGO was observed in 15 (29.4 %), GGO with crazy paving pattern was seen in 15 (29.4 %) and GGO mixed with consolidation was noted in 21(41.2 %). Peri-lesional or intralesional segmental or subsegmental pulmonary vessel enlargement was observed in 36 (70.6 %) cases. CONCLUSION: In this study population predominantly with mild symptoms and few comorbidities, two-thirds of RT-PCR positive patients had a normal chest CT; whereas the remaining patients showed typical findings of predominant GGOs with a bilateral distribution and peripheral predominance.

ABSTRACT

ABSTRACT Objectives The differentiation between the various etiologies of thyrotoxicosis, including those with hyperthyroidism (especially Graves' disease [GD], the most common cause of hyperthyroidism) and without hyperthyroidism (like thyroiditis), is an important step in planning specific therapy. Technetium-99m (99mTc) pertechnetate thyroid scanning is the gold standard in differentiating GD from thyroiditis. However, this technique has limited availability, is contraindicated in pregnancy and lactation, and is not helpful in cases with history of recent exposure to excess iodine. The aim of this study was to identify the diagnostic value of the peak systolic velocity of the inferior thyroid artery (PSV-ITA) assessed by color-flow Doppler ultrasound (CFDU) and compare the sensitivity and specificity of this method versus 99mTc pertechnetate thyroid uptake. Subjects and methods We prospectively analyzed 65 patients (46 with GD and 19 with thyroiditis). All patients were evaluated with clinical history and physical examination and underwent 99mTc pertechnetate scanning and measurement of TRAb levels and PSV-ITA values by CFDU. The diagnosis was based on findings from signs and symptoms, physical examination, and 99mTc pertechnetate uptake. Results Patients with GD had significantly higher mean PSV-ITA values than those with thyroiditis. At a mean PSV-ITA cutoff value of 30 cm/sec, PSV-ITA discriminated GD from thyroiditis with a sensitivity of 91% and specificity of 89%. Conclusion Measurement of PSV-ITA by CFDU is a good diagnostic approach to discriminate between GD and thyroiditis, with sensitivity and specificity values comparable to those of 99mTc pertechnetate thyroid uptake.

ABSTRACT

Hepatic subcapsular steatosis is a rare pattern of fatty infiltration of the liver exclusively described in diabetic patients undergoing peritoneal dialysis who had received insulin in peritoneal dialysate. We describe a first case of severe subcapsular hepatic steatosis in a young diabetic patient on high dose insulin therapy (with striking subcapsular fatty infiltration of the liver documented by CT and MRI) without any evidence of chronic renal disease and not undergoing peritoneal dialysis.
