Leishmaniasis is one of several neglected tropical diseases that warrant serious attention. A disease of socio-economically poor people, it demands safer and cheaper drugs that help to overcome the limitations faced by the existing anti-leishmanials. Complementary or traditional medicines might be a good option, with an added advantage that resistance may not develop against these drugs. CHR2797 Thus, the present investigation was performed to evaluate the anti-leishmanial efficacy of an ultra-diluted homeopathic medicine (
30c) in experimental visceral leishmaniasis (VL).
Compliant with strict ethical standards in animal experimentation, the study was performed in-vivo in inbred BALB/c mice which were injected intravenously with 1 × 10
promastigotes of
before (therapeutic) or after (prophylactic) treatment with
30c for 30 days. In other groups of mice (
= 6 per group), amphotericin B served as positive control, infected animals as the disease control, while the naïve controls included normal animals;dard pharmaceutical treatment.
This original study has shown that Iodium 30c had significant impact in controlling parasite replication in experimental VL, though the effect was less than that using standard pharmaceutical treatment.
To determine normative data for the inferior vena cava (VCI) diameter in euvolemic children and its correlation with different somatic parameters in a pediatric population at one center in Europe.
This prospective observational study enrolled healthy children aged 4 weeks to 18y that visited our outpatient clinic. Weight, height, body surface area, and age were recorded. The children were grouped according to weight, as follows (80 children/group) < 10 kg, 10-19.9 kg, 20-29.9 kg, 30-59.9 kg, and 60-90 kg. Children were placed in a supine position and, during quiet respiration, the maximum and minimum VCI diameters were measured with M-mode ultrasonography. The collapsibility index (CI) was also automatically calculated for each subject CI = [VCI maximum (expiratory) diameter - VCI minimum (inspiratory) diameter]/VCI maximum (expiratory) diameter.
From May 2016 through November 2018 we retrieved data for 415 children that underwent VCI diameter evaluations. 400 children were included (mean age 7.8y ± 5.8, mean weight 32 kg ± 24.4, 46 % girls). The VCI
and the VCI
were significantly correlated with age (r = 0.867, p < 0.001, r = 0.797, p < 0.001), height (r = 0.840, p < 0.001, r = 0.772, p < 0.001), weight (r = 0.858, p < 0.001, r = 0.809, p < 0.001), and BSA (r = 0.878, p < 0.001, r = 0.817, p < 0.001). Correlations between the CI and age, weight, height, and BSA were not statistically significant.
This prospective study provided reference values for sonographic measurements of VCI diameters in euvolemic children and might greatly assist in assessing fluid status in sick children.

The aim of this study was to investigate the association of clinical, laboratory, and ultrasound findings with the surgical diagnosis of adnexal torsion in a retrospective cohort of women operated for suspected torsion during pregnancy.
A multicenter retrospective study of pregnant women who underwent urgent laparoscopy for suspected adnexal torsion during 2004-2019 in three tertiary medical centers.
Adnexal torsion was found in 143/208 (68.8 %) cases. Women with adnexal torsion had lower parity and lower rates of previous cesarean section, but higher rates of fertility treatments and multiple gestations, and were more likely to report right lower abdominal pain, with shorter duration of symptoms (< 24 hrs) and vomiting but not nausea. Women with adnexal torsion were found to have higher rates of sonographic findings suggestive of ovarian edema, while normal-appearing ovaries on ultrasound were more common in women without torsion. A multivariate logistic regression analysis showed that complaints of right abdominal pain were positively associated with adnexal torsion (aOR [95 % CI] 5.03 (1.45-17.49), while previous cesarean delivery and ultrasound findings of normal-appearing ovaries were negatively associated with adnexal torsion (aOR of 0.17 (0.05-0.52) and 0.10 (0.02-0.43), respectively).
Clinical characteristics and ultrasound findings may be incorporated into the emergency room workup of pregnant women with suspected adnexal torsion.

Lumbar spinal drainage (LSD) can significantly facilitate brain relaxation and improve ease of surgical goals for a variety of neurosurgical indications. Although rapid drainage of large volumes of spinal fluid can theoretically produce shifts in brain compartments and herniation syndromes, the clinical significance of this phenomenon when LSD is used immediately before craniotomy is unclear.
To report a large single-surgeon consecutive experience with symptomatic brain herniation after lumbar drainage before craniotomy.
Included were 365 patients who underwent LSD with either lumbar drain or lumbar puncture for a variety of different neurosurgical pathologies between 2008 and 2018 immediately before craniotomy. We reviewed the surgical indications, craniotomy location, approach, type of LSD, presence of postoperative brain herniation on imaging, type of herniation, clinical symptoms, lesion pathology, and 30-d modified Rankin Scale score for each patient.
There was no patient who suffered from the deoperative adjunct that can be used to facilitate surgical objectives.
Trends in mechanical thrombectomy have emphasized larger bore aspiration catheters that may be difficult to deploy from a radial access point due to size constraints or need to obtain sheathless access. As such, many neurointerventionists are reticent to attempt thrombectomy through transradial access (TRA) for fear of worse outcomes.
To explore whether mechanical thrombectomy could be achieved safely and effectively through the transradial route.
We retrospectively analyzed the records of patients undergoing mechanical thrombectomy at our academic institute between January 2018 and January 2019, which corresponded to a time when we began to transition to TRA for neurointerventions, including mechanical thrombectomy. We compared the procedural details and clinical outcomes of patients undergoing mechanical thrombectomy using TRA with those using transfemoral access (TFA).
During the study period, 44 patients underwent mechanical thrombectomy with TRA and 129 with TFA. There was no statistically significant difference in door-to-access time, door-to-reperfusion time, or first-pass recanalization rate. There was no significant difference in modified Rankin Scale (mRS) score at discharge, mRS score at last follow-up, or length of stay. There were 7 access-site complications in the TFA group and none in the TRA group. One patient in the TRA group required crossover to TFA.
Mechanical thrombectomy can be performed safely and effectively from a TRA site without compromising recanalization times or rates. link2 TRA has superior access-site complication profiles compared to TFA.

This is a challenging surgical entity compared to typical intradural meningiomas, which nearly always eccentrically displace the cord. In these more common meningiomas, surgical access is fairly straightforward as the meningioma is often visualized upon opening the meninges. Resection can be more safely performed with the cord largely shifted. In cases of ventral meningioma, the tumor is hidden ventral to the spinal cord, and techniques to safely mobilize the spinal cord must be utilized. We demonstrate that an entirely posterior approach allows complete resection of a ventrally situated mass. link3 After careful identification and sectioning of the dentate ligament at multiple levels on the right side of the canal, we then suture and rotate the dentate ligament at each site, thereby allowing progressive visualization of the ventral meningioma. A narrow, but viable, working corridor to the tumor allows safe debulking. Once it is felt that the tumor can no longer be safely excised through the created corridor, we then disconnect our dentate sutures and move to the other side of the canal. Similarly, the dentate is sectioned and sutured so that the contralateral aspect of the meningioma can be visualized and debulked. The tumor can then be safely removed. A standard posterior approach and midline durotomy allows this bilateral approach to a ventrally situated meningioma and, therefore, in our mind, represents a safe and also highly effective road to resection. Patient consent was obtained prior to publication.
Brain metastases (BM) are the most common type of brain tumor malignancy in the US. They are also the most common indication for stereotactic radiosurgery (SRS). However, the incidence of both local recurrence and radiation necrosis (RN) is increasing as treatments improve. MRI imagery often fails to differentiate BM from RN; thus, patients must often undergo surgical biopsy or resection to obtain a definitive diagnosis.
To hypothesize that a marker of immunosuppression might serve as a surrogate marker to differentiate patients with active vs inactive cancer-including RN.
We thus purified and quantified Monocytic Myeloid-Derived Suppressor Cells (Mo-MDSC) by flow cytometry in patients proven by biopsy to represent BM or RN.
We report the utility of the previously reported HLA-Dr-Vnn2 Index or DVI to discriminate recurrent BM from RN using peripheral blood. The presence of CD14+ HLA-DRneg/low Mo-MDSC is significantly increased in the peripheral blood of patients with brain metastasis recurrence compared to RN (Average 61.5%vs 7%, n=10 and n=12, respectively, P<.0001). In contrast, expression of VNN2 on circulating CD14+ monocytes is decreased in BM patients compared to patients with RN (5.5%vs 26.5%, n=10 and n=12, respectively, P=.0008). In patients with biopsy confirmed recurrence of brain metastasis, the average DVI was 11.65, whereas the average DVI for RN patients was consistently <1 (Avg. of 0.17).
These results suggest that DVI could be a useful diagnostic tool to differentiate recurrent BM from RN using a minimally invasive blood sample.

Clonogenic assays are the gold standard method for in vitro assessment of radiosensitivity. Reproducibility is the critical factor for scientific rigor; however, this is reduced by insufficient reporting of methodologies. In reality, the reporting standards of methodologies pertaining to clonogenic assays remain unclear. To address this, we performed a literature search and qualitative analysis of the reporting of methodologies pertaining to clonogenic assays. A comprehensive literature review identified 1672 papers that report the radiosensitivity of human cancer cells based on clonogenic assays. From the identified papers, important experimental parameters (i.e. number of biological replicates, technical replicates, radiation source and dose rate) were recorded and analyzed. We found that, among the studies, (i) 30.5% did not report biological or technical replicates; (ii) 47.0% did not use biological or technical replicates; (iii) 3.
