OBJECTIVEIntraoperative imaging is increasingly being used for resection control in diffuse gliomas, in which the extent of resection (EOR) is important. Intraoperative ultrasound (iUS) has emerged as a highly effective tool in this context. Navigated ultrasound (NUS) combines the benefits of real-time imaging with the benefits of navigation guidance. In this study, the authors investigated the use of NUS as an intraoperative adjunct for resection control in gliomas.METHODSThe authors retrospectively analyzed 210 glioma patients who underwent surgery using NUS at their center. The analysis included intraoperative decision-making, diagnostic accuracy, and operative outcomes, particularly EOR and related factors influencing this.RESULTSUS-defined gross-total resection (GTR) was achieved in 57.6% of patients. Intermediate resection control scans were evaluable in 115 instances. These prompted a change in the operative decision in 42.5% of cases (the majority being further resection of unanticipated residual tumor). Eventual MRI-defined GTR rates were similar (58.6%), although the concordance between US and MRI was 81% (170/210 cases). There were 21 false positives and 19 false negatives with NUS, resulting in a sensitivity of 78%, specificity of 83%, positive predictive value of 77%, and negative predictive value of 84%. A large proportion of patients (13/19 patients, 68%) with false-negative results eventually had near-total resections. Tumor resectability, delineation, enhancement pattern, eloquent location, and US image resolution significantly influenced the GTR rate, though only resectability and eloquent location were significant on multivariate analysis.CONCLUSIONSNUS is a useful intraoperative adjunct for resection control in gliomas, detecting unanticipated tumor residues and positively influencing the course of the resection, eventually leading to higher resection rates. Nevertheless, resection is determined by the innate resectability of the tumor and its relationship to eloquent location, reinforcing the need to combine iUS with functional mapping techniques to optimize resections.

Intraoperative imaging has become one of the most important adjuncts in neurosurgery, especially in the surgical treatment of intra-axial tumors. Navigation and intraoperative magnetic resonance imaging have limitations, and intraoperative ultrasonography (IOUS) has emerged as a versatile and multifaceted alternative. With technological advances in ultrasound scanners and newer multifunctional probes, the potential of IOUS is increasingly being utilized in the resection of tumors. The addition of image guidance to IOUS has exponentially increased the power of this technique. Navigated ultrasonography (nUS) can now overcome many of the limitations of conventional standalone two-dimensional ultrasonography. In this pictorial essay, we outline our nUS technique (both two-and three-dimensional) for the resection of intra-axial tumors with illustrated examples highlighting the various steps and corresponding benefits of the technique.

Purpose:To find out the current physiotherapy practices in Intensive Care Unit (ICU) across Maharashtra.Materials and Methods:Study design was exploratory cross-sectional survey. Questionnaires were sent to the physiotherapists working in hospitals across Maharashtra state, India. Four weeks for completion of questionnaire was given in an attempt to ensure good response rates.Result:Of 200, 73 questionnaires were received representing a 36% response rate. The study revealed that 76% of the respondents were bachelors qualified, 15% were masters in physiotherapy with only 4% specialized in cardio-respiratory physiotherapy; 82% had <5 years experience in ICU. Almost 19% had not at all attended any seminars/workshops related to ICU management while 61% attended up to three within last 2 years. The availability of a physiotherapist during the night was affirmed by 63%, 58% responded initiation of physiotherapy to be “always physician referred” and 39% mentioned “physiotherapist initiated.” Almost 80% performed chest wall techniques, 86% positioning, 27% postural drainage, 5% manual hyperinflation, 12% application of nebulizer, and 56% bedsores management. Only 5% reported involvement in ventilator setting, 11% had their opinion sought before weaning from ventilator, 29% practiced noninvasive ventilation, 11% were involved in decision-making for extubation and 44% reported involvement in patient family education.Conclusion:The study showed that physiotherapists among the responding ICUs surveyed lack in experience and updated knowledge. Physician reference is necessary to initiate physiotherapy and there exists no established criteria for physiotherapy treatment in ICU. All physiotherapists were routinely involved in chest physiotherapy, mobilization, and positioning.

OBJECTIVEPatients with traumatic brain injury (TBI) often undergo repeat head CT scans to identify the possible progression of injury. The objective of this study is to evaluate the need for routine repeat head CT scans in patients with mild to moderate head injury and an initial positive abnormal CT scan.METHODSThis is a retrospective study of patients presenting to the emergency department from January 2016 to December 2017 with Glasgow Coma Scale (GCS) scores > 8 and an initial abnormal CT scan, who underwent repeat CT during their in-hospital medical management. Patients who underwent surgery after the first CT scan, had a GCS score < 9, or had a normal initial CT scan were excluded. Demographic, medical history, and physical examination details were collected, and CT scans were reviewed. Radiological deterioration, neurological deterioration, and/or the need for neurosurgical intervention were the primary outcome variables.RESULTSA total of 1033 patients were included in this study. These patients underwent at least two CT scans on an inpatient basis. Of these 1033 patients, 54.1% had mild head injury and 45.9% had moderate head injury based on GCS score at admission. The most common diagnosis was contusion (43.8%), followed by extradural hematoma (28.8%) and subdural hematoma (26.6%). A total of 2636 CT scans were performed for 1033 patients, with a mean of 2.55 per patient. Of these, 25 (2.4%) had neurological deterioration, 90 (8.7%) had a progression of an existing lesion or appearance of a new lesion on repeat CT, and 101 (9.8%) required neurosurgical intervention. Seventy-five patients underwent surgery due to worsening of repeat CT without neurological deterioration, so the average number of repeat CT scans required to identify one such patient was 21.3. On multiple logistic regression, GCS score at admission (p = 0.024), abnormal international normalized ratio (INR; p < 0.001), midline shift (p = 0.005), effaced basal cisterns (p < 0.001), and multiple hemorrhagic lesions (p = 0.010) were associated with worsening of repeat CT, neurological deterioration, and/or need for neurosurgical intervention.CONCLUSIONSThe role of routine repeat head CT in medically managed patients with head injury is controversial. The authors have tried to study the various factors that are associated with neurological deterioration, radiological deterioration, and/or need for neurosurgical intervention. In this study the authors found lower GCS score at admission, abnormal INR, presence of midline shift, effaced basal cisterns, and multiple lesions on initial CT to be significantly associated with the above outcomes.

Objective Despite the technological advancement in imaging, digital subtraction angiography (DSA) remains gold standard imaging modality for spontaneous subarachnoid hemorrhage (SAH). But even after DSA, around 15% of SAH remains elusive for the cause of the bleed. This is an institutional review to solve the mystery, “when is second DSA really indicated?” Methods In a retrospective review from January 2015 to December 2017, we evaluated cases of spontaneous SAH with initial negative DSA with repeat DSA after 6 weeks to rule out vascular abnormality. The spontaneous SAH was confirmed on noncontrast computed tomography (NCCT) and divided into two groups of perimesencephalic SAH (PM-SAH) or nonperimesencephalic SAH (nPM-SAH). The outcome was assessed by a modified Rankin’s score (mRS) at 6 months postictus. Result During the study period, we had 119 cases of initial negative DSA and 98 cases (82.3%) underwent repeat DSA after 6 weeks interval. A total of 53 cases (54.1%) had PM-SAH and 45 cases (45.9%) had nPM-SAH. Repeat DSA after 6 weeks showed no vascular abnormality in 53 cases of PM-SAH and in 2 (4.4%) out of 45 cases of nPM-SAH. At 6 months postictus, all cases of PM-SAH and 93% of nPM-SAH had mRS of 0. Conclusion We recommend, a repeat DSA is definitely not required in PM-SAH, but it should be done for all cases of nPM-SAH, before labeling them as nonaneurysmal SAH. Although the overall outcome for nonaneurysmal spontaneous SAH is better than aneurysmal SAH, nPM-SAH has poorer eventual outcome compared to PM-SAH.

Background: Bipedal locomotion is a unique feature of human beings and has the advantage of upright mobility. Hence, foot becomes the most important weight loading structure and gets the maximum pressure per unit area. Plantar fasciitis is a painful inflammatory process of the plantar fascia, the connective tissue on the sole of the foot. Thus a study was conducted to determine the effect of strain-counterstrain in plantar fasciitis.Methods: 30 individuals aged between 18-35 years both male and female with plantar fasciitis were recruited for the study. The patients were treated for a period of 7 days using the technique of strain-counterstrain. Pre-intervention and post-intervention scores of Plantar Fasciitis Pain and Disability scale were assessed and were analysed using unpaired t-test and repeated ANOVA.Results: There was equal distribution of occurrence of plantar fasciitis among both the genders out of the population of study.  A significant difference was noted between the pre and post interventional measure of a type of manual therapy called strain-counterstrain (p<0.0001). The difference between pre intervention and after third day intervention did not show much of a difference. However after fifth day a considerable difference was noted (p <0.0001).  It was noted that limited dorsiflexion improved after one week of interventional measure of strain-counterstrain (p <0.0001).Conclusions: The technique of strain-counterstrain which is a type of manual therapy is effective in patients affected by plantar fasciitis. It also showed an improvement in the limited ankle dorsiflexion range.
