Clinical Psychopharmacology and Neuroscience 2016;14(4):330-337
Neuro-stimulation techniques have gradually evolved over the decades and have emerged potential therapeutic modalities for the treatment of psychiatric disorders, especially treatment refractory cases. The neuro-stimulation techniques involves modalities like electroconvulsive therapy (ECT), repetitive transcranial magnetic stimulation (rTMS), transcranial direct current stimulation (tDCS), vagus nerve stimulation (VNS) and others. This review discusses the role of neuro-stimulation techniques in the treatment of anxiety disorders. The various modalities of neuro-stimulation techniques are briefly discussed. The evidence base relating to use of these techniques in the treatment of anxiety disorders is discussed further. The review then highlights the challenges in conducting research in relation to the use of neuro-stimulation techniques with reference to patients with anxiety disorders. The review provides the future directions of research and aimed at expanding the evidence base of treatment of anxiety disorders and providing neuro-stimulation techniques as promising effective and acceptable alternative in select cases.

Serous ovarian cancer is the most common malignant ovarian tumour. Traditional management consists
of surgical resection with postoperative chemotherapy. Currently neoadjuvant chemotherapy is offered
to patients with advanced stage disease. The present study aims to analyse the histomorphological
alterations in serous ovarian cancer following neoadjuvant chemotherapy. Correlation of these
morphological alterations with survival is also presented here. Serous ovarian cancers from 100
advanced stage cases were included; 50 were treated with pre-surgery chemotherapy. Semi-quantitative
scoring was used to grade the alterations in tumour morphology. Survival data was correlated with
the final morphological score. Tumour morphology was significantly different in cases treated with
neoadjuvant chemotherapy (CT group) as compared to cases with upfront surgery. The CT group
cases showed more fibrosis, calcification, and infiltration by lymphocytes, plasma cells, foamy
and hemosiderin-laden macrophages. The residual tumour cells had degenerative cytoplasmic
changes with nuclear atypia. Patients with significant morphological response had a longer median
survival, although it did not attain statistical significance in the current study. With the increasing
use of neoadjuvant chemotherapy in management, the pathologist needs to be aware of the altered
morphological appearance of tumour. Further studies are required to establish a grading system to
assess the tissue response which can be helpful in predicting the overall therapeutic outcome and
the prognosis of patients.

Renal cell carcinoma associated with fused ectopic kidneys has rarely been reported in the literature. Here we report the first case of robot-assisted heminephrectomy for chromophobe renal cell carcinoma in an L-shaped fused ectopic kidney. The present case report highlights the importance of three-dimensional vision and enhanced maneuverability with the EndoWrist technology of the robotic surgical system for precise dissection. This report also highlights the importance of preoperative contrast-enhanced computed tomography with three-dimensional arterial reconstruction for surgical planning.

PURPOSE: This study was performed to characterise the nature, clinical presentation, mode of insertion, and management of intravesical foreign bodies in patients treated at our hospital. METHODS: Between January 2008 and December 2014, 49 patients were treated for intravesical foreign bodies at King George Medical University, Lucknow. All records of these patients were retrospectively analysed to characterise the nature of the foreign body, each patient's clinical presentation, the mode of insertion, and how the case was managed. RESULTS: A total of 49 foreign bodies were retrieved from patients’ urinary bladders during the study period. The patients ranged in age from 11 to 68 years. Thirty-three patients presented with complaints of haematuria (67.3%), 29 complained of frequency of urination and dysuria (59.1%), and 5 patients reported pelvic pain (10.2%). The circumstances of insertion were iatrogenic in 20 cases (40.8%), self-insertion in 17 cases (34.6%), sexual abuse in 4 cases (8.1%), migration from another organ in 4 cases (8.1%), and assault in 4 cases (8.1%). Of the foreign bodies, 33 (67.3%) were retrieved by cystoscopy, while transurethral cystolitholapaxy was required in 10 patients (20.4%), percutaneous suprapubic cystolitholapaxy was performed in 4 patients (8.1%), and holmium laser lithotripsy was performed in 2 patients (4.08%). CONCLUSIONS: Foreign bodies should always be included in the differential diagnosis when evaluating a patient who presents with chronic lower urinary tract symptoms. A large percentage of foreign bodies can be retrieved using endoscopic techniques. Open surgical removal may be performed in cases where endoscopic techniques are unsuitable or have failed.

STUDY DESIGN: A prospective observational study. PURPOSE: To evaluate the role of nucleoplasty in the management of discogenic axial back pain; to determine the influence of concordant pain during provocative discography, annular tear and loss of disc height on the outcome of nucleoplasty. OVERVIEW OF LITERATURE: The role of nucleoplasty in the management of radicular leg pain due to disc herniation is known. However, the data regarding its role in the management of discogenic axial back pain is scarce. METHODS: A prospective evaluation of 30 patients with discogenic axial back pain undergoing nucleoplasty was performed. Pain, functional disability and quality of life were assessed using the 100 mm visual analogue scale (VAS), Oswestry Disability Index (ODI) and Short Form-36 (SF-36), respectively. RESULTS: The mean reduction in VAS was 31.03 and 29.03; mean reduction in ODI was 24.53 and 20.60; and mean increment in SF-36 was 13.58 and 12.30, at 6 months and at 12 months, respectively. The differences were statistically significant (p <0.05). Concordant pain during provocative discography, annular tear and loss of disc height did not affect a clinically significant improvement in any of the three outcomes (p =0.882, 0.213, and 0.170; respectively). CONCLUSIONS: Nucleoplasty produced statistically significant improvements in pain, functional disability and quality of life in patients with discogenic low back pain at 6 months and at 12 months. Concordant pain during provocative discography, annular tear and loss of disc height did not influence any of the outcomes after nucleoplasty in patients with discogenic axial back pain.

Clinical Endoscopy 2021;54(6):909-915
Background/Aims:
The management of patients with walled-off necrosis (WON) has undergone a paradigm shift from surgical to nonsurgical modalities. Real-world data on the management of symptomatic WON are scarce.
Methods:
Prospectively collected data of symptomatic WON cases were retrospectively evaluated. The treatment modalities used were medical management alone, percutaneous catheter drainage (PCD) or endoscopic drainage, or a combination of PCD and endoscopic drainage. We compared technical success, clinical success, mortality, readmissions, complications, and length of hospital stay among these modalities.
Results:
A total of 264 patients were evaluated (predominantly men: n=195, 74%). The mean age was 37.66 (±14.41) years. The etiology of acute pancreatitis was excessive alcohol consumption in 115 (44%) and biliary (gall stone, microlithiasis) in 89 (34%). The most common indications for drainage were pain (n=253, 96%) and fever (n=140, 53%). Of the patients, 74 (28%) were treated with medical therapy alone, 81 (31%) with endoscopic drainage, 98 (37%) with PCD, and 10 (4%) with a combined approach. Technical success and clinical success were achieved in 78 (93%) and 74 (91%) patients in the endoscopic arm and in 88 (90%) and 79 (81%) patients in the PCD arm, respectively (p=0.0004 for clinical success). Lower rates of complications (7% vs. 22%, p=0.005), readmission (20% vs. 34%, p=0.04), and mortality (4% vs. 19%, p=0.0012), and shorter hospital stay (13 days vs. 19 days, p=0.0018) were observed in the endoscopic group than in the PCD group.
Conclusions
Endoscopic drainage of WON is better than PCD and is associated with lower mortality, fewer complications, and shorter hospitalization.

Asian Spine Journal 2018;12(6):1100-1105
STUDY DESIGN: Prospective observational study. PURPOSE: To determine the incidence of postoperative urinary retention (POUR) in patients undergoing elective posterior lumbar spine surgery and identify the risk factors associated with the development of POUR. OVERVIEW OF LITERATURE: POUR following surgery can lead to detrusor dysfunction, urinary tract infections, prolonged hospital stay, and a higher treatment cost; however, the risk factors for POUR in spine surgery remain unclear. METHODS: A prospective, consecutive analysis was conducted on patients undergoing elective posterior lumbar surgery in the form of lumbar discectomy, lumbar decompression, and single-level lumbar fusions during a 6-month period. Patients with spine trauma, preoperative neurological deficit, previous urinary disturbance/symptoms, multiple-level fusion, and preoperative catheterization were excluded from the study. Potential patient- and surgery-dependent risk factors for the development of POUR were assessed. Univariate analysis and a multiple logistical regression analysis were performed. RESULTS: A total of 687 patients underwent posterior lumbar spine surgery during the study period; among these, 370 patients were included in the final analysis. Sixty-one patients developed POUR, with an incidence of 16.48%. Significant risk factors for POUR were older age, higher body mass index (BMI), surgery duration, intraoperative fluid administration, lumbar fusion versus discectomy/decompression, and higher postoperative pain scores (p < 0.05 for all). Sex, diabetes, and the type of inhalational agent used during anesthesia were not significantly associated with POUR. Multiple logistical regression analysis, including age, BMI, surgery duration, intraoperative fluid administration, fusion surgery, and postoperative pain scores demonstrated a predictive value of 92% for the study population and 97% for the POUR group. CONCLUSIONS: POUR was associated with older age, higher BMI, longer surgery duration, a larger volume of intraoperative fluid administration, and higher postoperative pain scores. The contribution of postoperative pain scores in the multiple regression analysis was a significant predictor of POUR.

Korean Journal of Anesthesiology 2020;73(5):417-424
Background:
Multiple comparative studies report that adductor canal blocks provide similar pain relief to femoral nerve blocks following total knee arthroplasty. However, adductor canal blockade fails to anesthetize several important femoral nerve branches that contribute to knee innervation. We sought to clarify this anatomic discrepancy by performing both blocks in sequence, using patients as their own controls. We hypothesized that patients would experience additional pain relief following a superimposed femoral nerve block, demonstrating that these techniques are not equivalent.
Methods:
Sixteen patients received continuous adductor canal block before undergoing knee arthroplasty under general anesthesia. In the recovery room, patients reported their pain score on a numeric scale of 0–10. Once a patient reached a score of five or greater, he/she was randomized to receive an additional femoral nerve block using 2% chloroprocaine or saline sham, and pain scores recorded every 5 min for 30 min. Patients received opioid rescue as needed. Anesthesiologists performing and assessing block efficacy were blinded to group allocation.
Results:
Patients randomized to chloroprocaine versus saline reported significantly improved median pain scores 30 min after the femoral block (2.0 vs. 5.5, P = 0.0001). Patients receiving chloroprocaine also required significantly fewer morphine equivalents during the 30 min post-femoral block (1.0 vs. 4.5 mg, P = 0.03).
Conclusions
Adductor canal block is a useful technique for postoperative pain following total knee arthroplasty, but it does not provide equivalent analgesic efficacy to femoral nerve block. Future studies comparing efficacy between various block sites along the thigh are warranted.

Background/Aims:
The severe acute respiratory syndrome coronavirus 2 pandemic has affected the gastrointestinal (GI) endoscopy units globally owing to the risk of transmission. We present our data on the use of rapid antigen test (RAT) as a screening tool prior to endoscopy to prevent the transmission of coronavirus disease (COVID-19).
Methods:
This study was a retrospective analysis of patients who underwent any GI endoscopic procedure from July 2020 to October 2020 at a tertiary referral center in New Delhi, India. All patients underwent screening for COVID-19 using RAT, and endoscopy was performed only when the RAT was negative. The data are presented as numbers and percentages.
Results:
A total of 3,002 endoscopic procedures were performed during the study period. Only one endoscopic procedure was performed in a COVID-19 positive patient. A total of 53 healthcare workers were involved in conducting these procedures. Only 2 healthcare workers (3.8%) were diagnosed COVID-19 positive, presumably due to community-acquired infection, during this period.
Conclusions
The COVID-19 RAT is easily usable as a simple screening tool prior to GI endoscopy during the COVID-19 pandemic.
