Aim:To study the adverse drug reaction (ADR) pattern in a pediatric population in a tertiary care hospital.Materials and Methods:An observational study was done in the department of pediatrics in a tertiary care hospital. The ADRs occurring in the inpatient wards and outpatient department of pediatrics were actively monitored. The collected reports were analyzed for ADR pattern, drug groups, demographic profile, causality, severity, and preventability of the ADR.Results:A total of 30 ADRs were documented during the mid period of 2009 among pediatric patients. Most of the ADRs (60%) occurred below the age of 1 year. Antibiotics comprised the major group of drugs causing ADRs (67%). Rashes and urticaria were the most common type of ADR (37%) followed by fever, anaphylactic shock, vomiting, chills, and rigors. A single case of death had been reported in the study period. There were more occurrences of ADRs with multiple drugs compared to single drug therapy. About 80% of the ADRs were of probable causality and 87% were of probable preventability. There were no mild reactions, with 77% of reactions being moderate and 23% of reactions being severe in the severity scale.Conclusions:ADRs occur more among infants and antibiotics were more commonly implicated. Most of the reactions were of moderate severity. This indicates the need for a rigid ADR monitoring among pediatric patients to ensure safety of drug therapy.
Objective:The objective of the study is to analyze the risk factors determining the outcomes of patients with emphysematous pyelonephritis (EPN) by the adoption of a standardized management algorithm as well as to develop a prognostic scoring model to risk stratify these patients.Materials and Methods:The hospital records of 72 consecutive patients with EPN from February 2012 to January 2018 were retrospectively reviewed. Demographic, clinicoradiographic, and laboratory characteristics were recorded. Patients were managed with a standard management protocol and based on outcomes divided into three groups. Group I survived with conservative management, Group II survived after emergency nephrectomy, and Group III expired. The risk factors for nephrectomy and mortality were analyzed.Results:The mean age was 53 years. Male to female ratio was 4:5. There were 61 (84.7%), 4 (5.6%), and 7 (10%) patients in Groups I, II, and III, respectively. Diabetes mellitus was the most common comorbidity detected in 62 (86%) of patients. Type II EPN was the most common radiological presentation observed in 32 (44%) patients. Overall survival rate was 90%, and kidney salvage rate was 80%. Escherichia coli was the most common organism isolated. Thirty-two (45%) patients exhibited resistance to third-generation cephalosporin antibiotics. Thrombocytopenia, low body mass index (BMI), presence of >2 comorbidities, high total leukocyte count (TLC), and hypoalbuminemia were significantly associated with mortality. On adoption of the prognostic scoring system, mortality rates according to the risk subgroups were as follows: favorable - 0%, intermediate - 19%, and poor - 100%.Conclusion:Conservative management adopting appropriate algorithm reduces mortality and avoids unnecessary emergency nephrectomies. Thrombocytopenia, low BMI, presence of >2 comorbidities, high TLC, and hypoalbuminemia were significantly associated with mortality.
Objective: The diagnosis and treatment of female urethral stricture disease (FUSD) are practiced variably due to the scarcity of data on evaluation, variable defi nitions, and lack of long-term surgical outcomes. FUSD is diffi cult to rule out solely on the basis of a successful calibration with 14F catheter. In this study, we have tried to characterize the variable clinical presentation of FUSD, the diagnostic utility of calibration, videourodynamic study(VUDS), and urethroscopy in planning surgical management. Materials and Methods: A retrospective review of records of 16 patients who underwent surgical management of FUSD was analyzed. The clinical history, examination fi ndings, and the results of all the investigations (including urofl owmetry, VUDS fi ndings, urethroscopy) they underwent, the procedures they had undergone ,and the follow-up data were studied. Results: A total of 16 patients underwent surgical management of FUSD. 13 out of 16 patients had successful calibration with 14F catheter on the initial presentation. These 13 patients on VUDS demonstrated signifi cant BOO and had variable stigmata of stricture on urethroscopy. The mean IPSS, fl ow rate, and PVR at presentation and after urethroplasty were 23.88±4.95, 7.72±4.25mL/s, 117.06±74.46mL and 3.50±3.44, 22.34±4.80mL/s, and 12.50±8.50mL, respectively. (p <0.05). The mean fl ow rate after endo dilation(17F) (n=12) was 11.4±2.5mL/s while after urethroplasty improved to 20.30±4.19mL/s and was statistically signifi cant(p <0.05). Conclusions: An adept correlation between clinical assessment, urethroscopy fi ndings, and VUDS is key in objectively identifying FUSD and planning surgical management. A good caliber of the urethra is not suffi cient enough to rule out a signifi cant obstruction due to FUSD. Early urethroplasty provides signifi cantly better outcomes in patients who have failed dilation as a treatment.
The primitive neuroectodermal tumor (PNET) of the kidney is an extremely rare neoplasm, the diagnosis of which mainly depends upon histopathology, immunohistochemistry (IHC), and cytogenetics. A handful of cases reported in the literature mention about aggressive features of this neoplasm. The purpose of our study was to review our experience in not only the diagnosis and management of the patients with renal PNET but also to highlight its propensity to involve inferior vena cava (IVC) and also present a rare occurrence of Ewing’s sarcoma (ES)/PNET of the renal pelvis. The clinical, operative, and histopathology records of four patients of renal PNET treated between January 2017 and December 2019 were reviewed and data analyzed concerning the available literature. Out of the four patients treated, two had level III and IV IVC thrombus, and one had dense desmoplastic adhesions with the IVC wall. One of the cases had a rare presentation of ES/PNET of the renal pelvis. All patients were managed surgically, while only one patient received adjuvant chemotherapy and following up with remission for the last 2 years and 4 months. On IHC, cluster of differentiation-99 (CD-99) was positive in all patients, and three were positive for Friend leukemia integration-1. PNET of the kidney is primarily an immunohistopathological diagnosis. This neoplasm has an increased propensity for the local invasion of surrounding structures. A multimodality approach with surgery, chemotherapy, and radiotherapy could offer better outcomes, although the prognosis of these tumors remains poor.
Background: Amikacin is a semisynthetic antibiotic used in the treatment of gram-negative bacterial infections and has a narrow therapeutic index. Although therapeutic drug monitoring is recommended for amikacin, it is not routinely performed because of the use of a less toxic once-daily regimen. Only few studies have evaluated the role of therapeutic drug monitoring in patients treated with amikacin. The objective of our study was to find an association between the pharmacokinetic parameters of amikacin and the time required for a clinical cure, creatinine clearance, and frequency of ototoxicity in patients with urinary tract infection treated for 7 or more days. Methods: A prospective study was conducted on patients with urinary tract infections who were administered amikacin for 7 or more days. Blood samples were obtained from the patients to measure the maximum drug concentration (Cmax) and trough concentration (Ctrough). Minimum inhibitory concentration (MIC) values were determined for patients with positive urine cultures. Serum creatinine levels were estimated every 3 days. The auditory assessment was performed using pure tone audiometry at baseline and weekly until the patients were discharged. Levels of amikacin were analyzed using a validated liquid chromatography-tandem mass spectrometry method. Results: Of 125 patients analyzed, the median time required for a clinical cure was less in the group of patients who achieved a Cmax/MIC ratio ≥8 than it was in those who did not achieve this level [7 versus 8 days (P = 0.02)]. The Ctrough of amikacin was associated with the change in serum creatinine level (P = 0.01) and the incidence of nephrotoxicity (P = 0.004). Conclusions: In patients receiving short-term amikacin therapy, Cmax/MIC value can be used to predict the time required for a clinical cure. Ctrough can be used to predict the occurrence of nephrotoxicity in patients receiving amikacin therapy.
Benign prostatic hyperplasia (BPH) is one of the common benign conditions in ageing males. Even though the aetiology BPH is unknown, inflammation is considered as one of the major factors in the development of BPH (Arivazhagan et al., 2017).Interleukin-23 (IL-23) is a pro-inflammatory cytokine which belongs to the family of the IL-12 family of cytokine and plays a role in the production of interleukin-1 and tumour necrosis factorα (Alhasani & Yousif, 2013). IL-23 has been suggested to promote the development of castration-resistant prostate cancer (Yan et al., 2018). A recent study has demonstrated increased IL-23 levels in metastatic prostate cancer (Yousif et al., 2014).Pentraxin-3 is an inflammatory mediator which regulates inflammatory reactions and apoptosis (Rutkowski et al., 2010). Pentraxin-3 is produced by inflammatory cells in response to cytokines like interleukin-1 beta (IL-1β) and tumour necrosis factor-alpha (TNFα). Pentraxin-3 expression has been demonstrated in prostate tissuein BPH and prostate cancer by earlier investigators and suggested that pentraxin-3 can predict the development of prostate cancer (Stallone et al., 2014).Matrix metalloproteinases are proteolytic enzymes, involved in angiogenesis and tumour development (Itoh & Nagase, 2002). Elevated expression of MMP-9 has been documented in BPH and prostate cancer patients by previous studies (Baspinar et al., 2017). Experimental studies have demonstrated reduction in proliferation of prostate
