Prevalence and risk factors for chronic pulmonary aspergillosis in chronic obstructive pulmonary disease patients with acute exacerbations.

Chronic obstructive pulmonary disease (COPD) patients often experience acute exacerbations requiring hospitalization. Recently, attention has focused on Aspergillus sensitization in the airways of these COPD patients. This study aimed to assess the prevalence of chronic pulmonary aspergillosis (CPA) in COPD patients with acute exacerbations and identify associated risk factors. A cross-sectional descriptive study was conducted at the Jawaharlal Institute of Postgraduate Medical Education and Research from January 2021 to June 2022. Sixty-one COPD patients presenting with acute exacerbations were included. Demographic details, blood investigations, and sputum examinations were performed for all patients. A high-resolution computed tomography thorax was conducted for eligible patients. The prevalence of CPA among patients with an acute exacerbation of COPD was found to be 9.8%, with chronic cavitary pulmonary aspergillosis being the most common presentation (50%). Among post-tubercular COPD patients, the prevalence of CPA was significantly higher at 22.7%. Hemoptysis (p<0.001) and a previous history of tuberculosis (p=0.008) were associated with Aspergillus sensitization. This study highlights the substantial prevalence of CPA in COPD patients with acute exacerbations, particularly in those with a history of tuberculosis. Early recognition and targeted management of CPA in COPD patients may improve outcomes and reduce hospitalization rates. Further large-scale multi-center studies are needed to validate these findings and comprehensively address the impact of CPA on all COPD patients.

Can combined non-invasive methods improve diagnosis of lung cancer?

Background: Lung cancer is the most common malignancy in both gender. Early diagnosis is needed to reduce morbidity and mortality. There is a debate about the most accurate investigating modality for the diagnosis of lung cancer. Methods: It is a retrospective cohort analysis to determine whether an approach of combined contrast-enhanced computed tomography (CECT) thorax with bronchoscopy method has higher sensitivity and specificity than combined CECT thorax with sputum cytology method. Records of patients with lung cancer who had visited the hospital within the last 6 months were retrospectively analyzed for their diagnostic modality. SPSS version 19 software was used for statistical analysis of the data. CECT scan thorax, bronchoscopy, and sputum cytology for lung cancer patients were analyzed. The CECT thorax plus bronchoscopy method was compared with the CECT thorax plus sputum cytology method. Their sensitivity, specificity, positive predictive value, negative predictive value, and accuracy in diagnosing lung cancer were analyzed. Results: Sixty-two patients were considered, including 62.9% males with a mean age of 55.5 years. In patients diagnosed with lung cancer, CECT thorax combined with bronchoscopy method was found to have a sensitivity of 96.67% than CECT thorax combined with sputum cytology method with a sensitivity of 90% and the difference in sensitivity between all individual approaches as well as the combined method was statistically significant with a P = 0.00001 and Chi-square value of 86.5909 owing to the low sensitivity of sputum cytology. CECT thorax combined with sputum cytology approach had a better specificity than CECT thorax combined with bronchoscopy. Conclusion: Combined CECT thorax with sputum cytology method has a better specificity in diagnosing lung cancer than combined CECT thorax with bronchoscopy method.

Risk factors of intracranial haemorrhage in preeclampsia: a case-control study.

Intracranial haemorrhage (ICH) is an uncommon but one of the most devastating and potentially fatal complications of preeclampsia. Most ICHs in pregnancy are reported in the absence of a vascular lesion, and severe systolic hypertension is thought to be an important risk factor even though many reports suggest that ICH can complicate preeclampsia even at lower blood pressure levels. In this case-control study of preeclamptic women, risk factors associated with ICH were compared in women who did and did not develop ICH. During the study period, ICH occurred in 1.8% (42/2167) pregnancies with preeclampsia, with 45.2% (n = 19/42) resulting in maternal mortality. HELLP syndrome (OR = 11.5; 95% CI 3.8-34.8), multiparity (OR 3.2; 95% CI 1.4-7.7), nausea/vomiting (OR = 3.6; 95% CI 1.4-9.3), and lower educational attainment (OR = 38.2; 95% CI 3.5-423.6) were associated with the increased probability of ICH. The incidence of caesarean birth (n = 29, 74.4% vs. n = 161, 34.5%) and neonatal mortality (n = 4, 13.3% vs. n = 17, 4.0%) were higher among preeclamptic who have ICH compared to those who did not have it. Improving awareness as well as early identification of those at risk of preeclampsia and complications can limit the impact of ICH among pregnant women with preeclampsia, especially in low- to middle-income countries.

Evaluation of change in tumor stiffness measured by acoustic radiation force impulse imaging for early prediction of response to neoadjuvant chemotherapy in breast cancer.

OBJECTIVES: In this study, the role of change in tumor stiffness between pre- and post-two cycles of neoadjuvant chemotherapy (NACT) measured by Acoustic Radiation Force Impulse (ARFI) imaging for predicting the response to NACT in breast cancer was analyzed. METHODS: Fifty-two adult women with biopsy-proven locally advanced breast cancer and early-stage breast cancer who received NACT followed by either modified radical mastectomy or breast conservation surgery were included in the study. Tumor stiffness represented by shear wave velocity (SWV) in meter per second by ARFI imaging was measured before and after two cycles of NACT. Participants were categorized into responders and nonresponders based on pathological response assessment from the postoperative specimen. The association of change in tumor stiffness between pre- and post-two cycles of NACT with final pathological response status was assessed. RESULTS: The mean change in SWV before and after completion of two cycles of NACT was 0.42 ± 0.16 and 0.17 ± 0.11 m/s in responders and nonresponders, respectively, and this difference was proven to be statistically significant (p < 0.001) suggesting that tumors that exhibit a larger reduction in tumor stiffness, respond better. An SWV reduction cut-off of 0.295 m/s between baseline and post-two cycles of NACT was also arrived at, which can discriminate between responders and nonresponders with a sensitivity and specificity of 88% and 83%, respectively. CONCLUSION: Difference in tumor stiffness measured by ARFI imaging before and after two cycles of chemotherapy can be used as a reliable early predictor of response to chemotherapy in breast cancer.

Risk factors for posterior reversible encephalopathy syndrome in hypertensive pregnant women presenting with seizures.

Pregnant women developing generalised tonic-clonic seizures in the absence of a prior neurological disorder are often diagnosed as eclamptic. Posterior reversible encephalopathy syndrome (PRES) is a distinct neuroimaging condition associated with long-term sequelae, which may occur in pregnancy. Some reports suggested PRES to be the pathophysiological process leading to eclampsia, whereas others observed PRES and eclampsia to have varying clinical severity and risk factors. In this case-control study, risk factors associated with PRES were compared to those for eclampsia in women with hypertension presenting with seizures who had undergone neuroimaging. PRES was noted to occur in 22.5% (51/227) hypertensive pregnant women presenting with seizures that otherwise would have been classified as eclampsia. An additional 51 women with eclampsia underwent neuroimaging. Women who had PRES had higher systolic (155.3 vs 144.5, p = 0.04), diastolic (99.2 vs 93.4, p = 0.006) and mean (117.9 vs 110.4, p = 0.001) blood pressure at admission compared to those with eclampsia. Eclampsia and PRES may occur through a similar pathophysiological mechanism, resulting in the same spectrum of neurological complications of preeclampsia, with PRES being the severest form of the disease process. PRES is difficult to differentiate from eclampsia based on clinical and laboratory investigation, except for high blood pressures, without adjunctive MRI/CT neuroimaging. Future studies should assess the role of biomarkers as well as long-term neurological sequelae in pregnant women with a diagnosis of PRES.

Limb body wall complex complicating a dichorionic diamniotic twin pregnancy: MRI for demonstration of fetal morphology.

Limb body wall complex (LBWC) is a rare, lethal malformation characterised by body wall defects, craniofacial and limb anomalies with or without various other organ anomalies. We report a case of dichorionic diamniotic twin pregnancy discordant for LBWC, diagnosed by ultrasound (US) and confirmed by MRI at 21 weeks' gestation, managed expectantly and delivered at 35 weeks by emergency caesarean section with a favourable outcome of the unaffected twin. The anomalous twin, who died soon after birth, had a sizeable thoracoabdominal wall defect, eviscerated liver and bowel loops attached to the placenta, short cord, ectopia cordis, lung hypoplasia, kyphoscoliosis, right upper limb amelia and left clubfoot with polydactyly. MRI helps to demonstrate the fetal morphology better when there are limitations to the US due to unfavourable fetal position, multifetal gestation, maternal obesity or reduced liquor. In twin pregnancies, the management will depend on ensuring the survival of the unaffected twin.

Klippel-Trenaunay syndrome in a young patient with the involvement of gastrointestinal and genitourinary tracts: an unusual and rare presentation.

Klippel-Trenaunay syndrome (KTS) is a rare congenital disorder characterised by capillary and venous malformations and soft-tissue hypertrophy with or without lymphatic malformation. The involvement of the gastrointestinal tract and genitourinary tract is uncommon in KTS. We present a case of a young adult who presented to us with bleeding per rectum and varicosities of the left lower limb. The patient was evaluated and diagnosed to have KTS. The patient was managed conservatively. To best of our knowledge, this is the first case report in literature where KTS was associated with atypical varicose veins of the left lower limb with mild hypertrophy of the lower limb, localised hypertrophy of the right gluteal region with involvement of pelvis, rectum, bladder and seminal vesicle.

Comparison of proximal and distal corticosteroid injections for carpal tunnel syndrome.

INTRODUCTION: Evidence for the efficacy of distal corticosteroid injection compared with proximal injection in carpal tunnel syndrome (CTS) is inadequate. METHODS: We conducted a randomized, double-blind noninferiority trial of 131 wrists with CTS. Forty milligrams of methylprednisolone was injected medial to the palmaris longus tendon 2 cm proximal to the wrist crease, or at the volar aspect, 2 to 3 cm distal to the wrist crease. Proximal & distal groups received a placebo. The primary outcome was difference in CTS Symptom Severity Scale (SSS) score at 1 month. Secondary outcome measures included the difference in SSS score at 3 months, Functional Status Scale (FSS) score at 1 and 3 months, and pain of injections. RESULTS: No significant differences were noted between groups in scores on the SSS and FSS. Pain was lower in the proximal group compared with the distal group. DISCUSSION: Corticosteroid injections for CTS distal to the wrist are not inferior to proximal injections, yet they are more painful.

Effect of Hypofractionated, Palliative Radiotherapy on Quality of Life in Late-Stage Oral Cavity Cancer: A Prospective Clinical Trial.

CONTEXT: The study was designed to evaluate the effect of a hypofractionated, palliative conformal radiotherapy regimen of 5250 cGy in 15 fractions in inoperable/incurable oral cavity carcinoma. AIMS: The primary objective was to assess the change in the quality of life (QOL) with respect to pain and mouth opening pre- and post-radiotherapy using standardized questionnaires. The secondary objective was to assess overall QOL using the same questionnaires and also to assess response rates, survival, compliance, early and late toxicity. SETTINGS AND DESIGN: This was a single-arm, prospective trial. Patients with incurable oral cavity cancer referred for palliative intent radiotherapy to the Department of Radiotherapy, RCC, JIPMER were recruited into the study. SUBJECTS AND METHODS: Forty-eight patients were recruited and twenty-five patients were given conformal radiotherapy to a dose of 52.5 Gy in 15 fractions. QOL was assessed using the European Organization of Research and Treatment of Cancer (EORTC) questionnaires before and 2 months after the completion of radiotherapy. The response assessment was made using the Response Evaluation Criteria in Solid Tumors (RECIST) criteria 2 months after radiotherapy. The early and late toxicities were assessed at 2 months and 6 months after radiotherapy completion, respectively. STATISTICAL ANALYSIS USED: Sample size was calculated to be 53. The Wilcoxon signed-rank test was used to compare QOL scores pre- and post-radiotherapy. Median survival was assessed using the Kaplan-Meier method. RESULTS: There was a significant improvement in the pain, mouth opening, speech, social contact, social eating, felt ill items of the EORTC QLQ-H and N35 questionnaire and role functioning, emotional functioning, social functioning, fatigue, pain, insomnia, appetite loss, financial difficulties, and Global QOL subscales of the QLQ-C30 questionnaire. 72% of the patients had grade 3 acute radiation oral mucositis and 36% had grade 3 acute radiation dermatitis. There were no significant treatment breaks due to toxicity. There were no grade 3 late toxicities observed. Overall median survival was 5.1 months. The overall response rate was 47%. The median time to treatment completion was 24 days. CONCLUSIONS: The improvement in QOL parameters suggests that the regimen of 52.5 Gy in 15 fractions is suitable for palliative intent radiotherapy in late-stage oral cavity cancer for effective palliation for short periods.

Role of Ultrasound to Monitor Patients With Carpal Tunnel Syndrome Treated With a Local Corticosteroid.

OBJECTIVES: Carpal tunnel syndrome (CTS) is an entrapment neuropathy resulting from compression of the median nerve at the carpal tunnel (CT). We assessed the role of high-resolution ultrasound (US) in monitoring patients with CTS treated with corticosteroid injection. METHODS: We performed high-resolution US evaluations of the wrists of patients with CTS before and after treatment with local corticosteroid. Thirty-nine and 17 wrists were included for analysis at the end of 1 and 3 months, respectively. The cross-sectional area (CSA) and anteroposterior diameter (APD) of the median nerve at the CT and clinical and electrophysiologic data were recorded. We assessed whether changes in US measurements before and after the treatment correlated with clinical and electrophysiologic parameters. RESULTS: The Boston symptom severity scale (p < .01), Boston functional status scale (p < .01), median nerve motor latency (p = .017), median nerve sensory velocity (p = .003), and difference in motor latencies (p = 0.03) and difference in sensory latencies (p = .03) between median and ulnar nerves showed significant changes over 1 or/and 3 months compared to baseline values. Changes in the CSA and APD correlated with changes in some clinical and electrophysiologic parameters. However, measurements of the CSA and APD at 1 or 3 months were not significantly different from baseline values. CONCLUSIONS: High-resolution US parameters such as the APD and CSA of the median nerve at the CT inlet were not useful to monitor patients with CTS treated with corticosteroid injections.

Isolated hepatobiliary tuberculosis: a diagnostic challenge.

Hepatobiliary system involvement is frequently seen as part of disseminated tubercular infection. But primary isolated hepatobiliary tuberculosis with no evidence of tuberculosis elsewhere in the body is extremely rare. Isolated hepatobiliary tuberculosis can cause diagnostic dilemma as the clinical, laboratory and imaging features are non-specific in majority of the cases. We report the case of a 50-year-old woman who presented with hepatobiliary tuberculosis with no pulmonary or extra hepatic involvement. Liver function tests were abnormal and ultrasonography (USG), CT and MR cholangiopancreatography showed multiple focal lesions in the liver. The diagnosis of tuberculosis was confirmed by a USG-guided biopsy of the liver lesions. In endemic regions with the presence of supportive imaging findings, in the appropriate clinical setting, the possibility of hepatic tuberculosis should be considered and diagnosis has to be confirmed with histopathological examination.

Complicated acute cerebellitis with obstructive hydrocephalus and tonsillar herniation in a child.

Acute cerebellitis (AC) is a rare inflammatory syndrome presenting as cerebellar dysfunction, seen more frequently in children. AC can have a variable course with features of cerebellar dysfunction, raised intracranial pressure and neurological deficits, and can sometimes even be potentially fatal due to complications such as obstructive hydrocephalus and brainstem compression, warranting surgical intervention. We report a case of a 12-year-old boy who presented with raised intracranial pressure and ataxia. Imaging with CT and MRI showed AC with obstructive hydrocephalus and tonsillar herniation. He was managed with medications for raised intracranial pressure and with ventriculoperitoneal shunt, and he recovered completely over a period of 2 weeks. Imaging has an important role in the diagnosis of AC and in differentiating it from acute cerebellar ataxia, which has a more benign course. It is crucial to diagnose and promptly manage the rarely occurring but life-threatening complications of AC.

A rare pediatric case of grossly dilated ureter presenting as abdominal mass.

Renal masses account for 55% of cases presenting as palpable abdominal mass in children.[1] An eight year male presented with palpable abdominal mass and pain. The patient underwent renal dynamic scan, which raised possibility of left duplex kidney with non-functioning moiety, as the size of left kidney was smaller than seen on Ultrasonography (USG). Magnetic resonance (MR)urography confirmed the findings with patient undergoing left hemi-nephrectomy and is doing well. In case of discrepancy in size of kidney on USG and renal scan, duplex kidney should be considered as differential, other causes being, renal cyst, benign/malignant mass and renal calculi. Gross hydro-ureter presenting as palpable abdominal mass is very rare with few reported cases.[234].

Hirayama disease: imaging profile of three cases emphasizing the role of flexion MRI.

We report three cases of Hirayama disease, cervical flexion myelopathy presenting as unilateral or bilateral asymmetric muscular atrophy of forearm and hand involving C7 - T1 myotomes in young males. MRI revealed asymmetric cord atrophy, altered signal intensity of cord, posterior dural detachment and enlarged posterior epidural space with multiple flow voids. This article emphasizes the role of Flexion MRI in diagnosing Hirayama disease.
