Role of Fine Needle Aspiration Cytology in the Rapid Diagnosis of Pulmonary Infections in Renal Allograft Recipients with Respiratory Failure.

Background: Renal transplantation is the treatment of choice in patients with end-stage renal disease. However, allograft recipients are at a higher risk of infection due to immunosuppressive therapies. This study aimed to analyze the utility of fine needle aspiration cytology (FNAC) lung in the etiological diagnosis of pulmonary infections in renal allograft recipients with respiratory failure. Materials and Methods: This is a retrospective study done in post-renal transplant patients presenting with pulmonary infections and respiratory failure in the past 7 years, in whom image-guided lung FNAC was done for diagnosis. Results: A total of 35 renal allograft recipients presenting with respiratory failure and having focal or diffuse pulmonary opacities (lesions) on radiological imaging were subjected to lung FNAC. The mean age of the patients was 41.1 ± 11.8 years (range 19-72), with the majority being males (n = 28, 80%); six (17.1%) of them were on invasive ventilation. The diagnostic yield of FNAC in our cohort was 77.1% (27 out of 35). Microorganisms were isolated in 21 cases (60%), with Nocardia being the most common (nine cases, 25.7%), Mycobacterial tuberculosis identified in six patients (17.1%), Aspergillus in three (8.6%), and one (2.9%) each had atypical Mycobacterium, zygomycetes, and Cryptococcus. FNAC suggested viral cytopathic effect in five patients, and cytomegalovirus (CMV) quantitative polymerase chain reaction test was found positive in four of these. One case was diagnosed as adenocarcinoma lung. Conclusion: Lung FNAC is a useful for establishing the etiological diagnosis of pulmonary lesions in renal transplant patients with respiratory failure.

Comparison of Efficacy and Safety of a Combination of Tamsulosin and Mirabegron versus Tamsulosin Alone in the Management of Overactive Bladder in Males with Lower Urinary Tract Symptoms - TAME-Overactive Bladder: An Open-labeled Randomized Controlled Trial.

Background: Overactive bladder (OAB) is a common condition in elderly men with coexisting benign prostatic enlargement (BPE), and it significantly impairs their quality of life (QoL). Aim: This study aimed to assess the safety and efficacy of adding beta-3 adrenergic receptor agonist (mirabegron 50 mg) to tamsulosin 0.4 mg for symptomatic men with BPE and OAB symptoms (OABS). Materials and Methods: It was an open-labeled randomized controlled trial. Ninety men with BPE and International Prostate Symptom Score (IPSS) of more than seven with predominant OABS were enrolled for the study. A detailed history, uroflowmetry, and baseline scores, including IPSS, OABS score (OABSS), and QoL assessment, were done for each patient. After written informed consent, patients were randomized into two groups of 45 each. Group-1 received tamsulosin 0.4 mg and placebo, and Group-2 received a combination of tamsulosin 0.4 mg plus mirabegron 50 mg once daily at bedtime. Follow-up of patients was done at 2nd, 4th, and 8th weeks. Efficacy at 8 weeks was assessed using repeat history for symptoms, uroflowmetry, IPSS, OABSS, and QoL score. Results: After 8 weeks of therapy, collected data were compared to baseline parameters in both groups. Significant improvement with respect to OABSS (P = 0.046), IPSS (P = 0.006), and QoL (P = 0.038) was observed with combination therapy versus tamsulosin alone. There were mild adverse effects, which were self-limiting. Conclusions: A combination of tamsulosin with mirabegron is effective and safe in improving the OABSS, IPSS, and QoL in men with BPE who have predominant OABS.

Clinical Profile and Outcome in Patients of Complicated Urinary Tract Infections: A Single-Center Prospective Observational Study.

Background: Complicated urinary tract infection (cUTI) is the one which is associated with structural and functional abnormalities of the urinary tract, thus increasing the risk of infection and failure of therapy. Aim: This study aims to determine the risk factors, changing trends in etiology, current treatment options, and outcomes in cUTI. Materials and Methods: This prospective observational study was done on patients presenting with cUTI. Hematological, biochemical workup, urine routine, urine culture, blood culture, ultrasonography, and wherever necessary computerized tomography of the genitourinary tract was done. The medical/surgical interventions and outcomes in these patients were recorded. Results: A total of 100 patients were enrolled in the study. Diabetes mellitus was the most common risk factor present in 53%. The most common organism isolated in urine culture was Escherichia coli (48%) followed by Klebsiella pneumoniae (19%) and similar trend but lesser positive yield was there in blood culture (Escherichia coli - 26% followed by Klebsiella pneumoniae - 3%). The organisms were most susceptible to colistin/polymyxin (100%) followed by carbapenems (88%), and later were the most commonly used empirical antibiotics in our study, yielding 95% survival rate. Surgical interventions (percutaneous/endourological) were required in 28%, renal replacement therapy in 14%, intensive care in 40% and mechanical ventilation in 10%, with 4% overall mortality at the end of 1-month follow-up. The mean duration of hospital stay was 9.1 ± 2.7 days. Conclusion: Escherichia coli was the most common organism causing cUTI, with diabetes being the most common risk factor. Most of the patients were treated with carbapenems with excellent survival outcomes.

A Randomized Controlled Trial to Study the Rationale of Antibiotic Prophylaxis in Diagnostic Rigid Cystoscopy: A Relook in The Era of Antibiotic Stewardship.

BACKGROUND: In the era of widespread antibiotic (AB) resistance, the role of prophylaxis in diagnostic cystoscopy is controversial. AIM: This study aimed to compare the incidence of postcystoscopy positive urinary culture (PC-PUC) and urinary tract infection (UTI) in patients undergoing diagnostic rigid cystoscopy with and without prophylaxis with preprocedural single-dose intravenous AB. MATERIALS AND METHODS: This prospective study was done in patients with preprocedural sterile urine undergoing elective diagnostic rigid cystoscopy. Patients were randomized into two groups, with one group receiving preprocedure single dose of intravenous cefuroxime sodium as prophylaxis half to 1 h before the procedure (Group AB prophylaxis) and the other group receiving no antibiotic prophylaxis (Group NAB). All patients were followed up till 1-month postprocedure, for any symptoms of urinary infection, mandatory urine microscopy and culture at 24-48 h, 1 week and 4 weeks post procedure, and addition sample in case of any urinary symptoms or fever. RESULTS: A total of 225 patients were studied, with 110 in AB prophylaxis and 115 in NAB groups. The use of prophylaxis did not decrease the incidence of PC-PUC (8.7%-3.6%; P = 0.167) or UTI (6.1%-1.8%; P = 0.102). Females and diabetics had significantly higher risk of PC-PUC, on univariate and multivariate analysis, not affected by prophylaxis. CONCLUSION: Preprocedural AB prophylaxis does not decrease the incidence of postcystoscopy bacteriuria significantly. Females and diabetics have significantly increased risk, but prophylaxis has no role in them either.

Pregnancy-related acute kidney injury and urological comorbidities in morbidly adherent placenta: A potential challenge to AKI-0by25.

Pregnancy-related acute kidney injury (PRAKI) and urological complications can significantly increase the maternal morbidity and mortality, and morbidly adherent placenta (MAP) has been found to increase the risk of both. This is a four-year prospective study, conducted on patients with MAP. Baseline parameters (demographic/antenatal/perinatal), operative details (obstetric/urological/hemostatic), peri-operative complications (AKI/urological), and maternal/fetal outcomes were studied till six weeks after delivery. Statistical analysis was done using IBM SPSS Statistics version 21.0, and P <0.05 was considered statistically significant. Out of the 5475 deliveries conducted in the study period, 64 had adherent placentation. AKI occurred in 39.1% of patients, with severe AKI (AKIN-2, 3) in 10.9%, and significantly higher incidence in placenta percreta (P = 0.021, relative risk [RR] - 2.34), urological injuries (P = 0.001, RR - 2.86), and high blood loss (P = 0.001) on univariate analysis, but placenta percreta was the most statistically significant factor P = 0.049) on multivariate analysis. Urological involvement/injuries requiring intervention were encountered in 22 patients, with statistically significantly high incidence in placenta previa (P = 0.023, RR - 1.62), placenta percreta (P = 0.000, RR - 17.18), and patients undergoing hysterectomy (P = 0.000, RR - 2.01) on univariate analysis, but placenta percreta was most statistically significantly implicated on multivariate analysis (P = 0.017). AKI and urological injuries significantly increased the need for intensive care and days of hospitalization. On six-week follow-up, all AKI patients recovered completely; no urinary leak or vesico-vaginal fistula was seen in urologically intervened patients and no maternal mortality occurred. There is an alarmingly high incidence of PRAKI and urological complications in MAP, posing a great threat to their worldwide improving statistics. Awareness of this condition among renal fraternity can significantly improve the maternal renal and overall prognosis.

Influence of hemodynamics and intra-operative hydration on biochemical outcome of renal transplant recipients.

BACKGROUND AND AIMS: Early graft function is crucial for successful kidney transplantation. The aim of our study was to evaluate the effect of intra-operative central venous pressure (CVP) and mean arterial pressure (MAP) on early graft function and biochemical outcome. MATERIAL AND METHODS: This was a retrospective study carried out on patients undergoing renal transplant only from live-related donors between March 2011 and May 2013. We mainly divided the patients into two groups based on CVP and mean MAP. One group had CVP more than 12 and other with CVP <12 mmHg at the time of declamping. Further one group was with mean MAP >100 mmHg and other with mean MAP of <100 mmHg. The graft outcome of genetically related and genetically unrelated donors was also evaluated in early postoperative period. The trend in fall of serum creatinine was studied during the first five post-operative days. The effect of age, dry weight, sex, relation with donor and intraoperative factors like MAP and CVP on early graft function were analysed. Correlation analysis, analysis of variance test (ANOVA) and multivariate analysis technique were used in this study for statistical computation. RESULTS: The mean CVP at the time of declamping was 13.91 mmHg. The minimum CVP was 6 mmHg in one patient who had ischemic heart disease with low ejection fraction. All 5 days mean serum creatinine values were comparable in two groups on 1(st), 2(nd), 3(rd) and 4(th) postoperative days. The mean MAP at the time of declamping was 111.22 mmHg. Mean MAP varied from a minimum of 95 mmHg to maximum of 131 mmHg. There was no significant difference in two groups on 1(st), 2(nd), 3(rd), 4(th) and 5(th) postoperative days. CONCLUSION: A CVP around 12 mmHg and mean MAP >95 mmHg with good perioperative fluid hydration is associated with good early graft function.

Subdural haematoma in an adult due to hypernatraemia.

Neurological manifestations are quite common in hypernatraemia but subdural haematoma due to hypernatraemia is very rare in adult population. We report a case of 50 year old female patient who presented with acute acalculus cholecystitis who subsequently developed persistent hypernatraemia with multiple subdural haematomas and patient died. Patient died because of persistently raised intracranial tension, before she could be taken up for surgical evacuation of subdural haematoma.
