A modified robust confidence interval for the population mean of distribution based on deciles
Authors: Abu-Shawiesh Moustafa Omar Ahmed , Sinsomboonthong Juthaphorn , Kibria Bhuiyan Mohammad Golam 
Published: October 2022

Abstract
The confidence interval is an important statistical estimator of population location and dispersion parameters. The paper considers a robust modified confidence interval, which is an adjustment of the Student’s t confidence interval based on the decile mean and decile standard deviation for estimating the population mean of a skewed distribution. The efficiency of the proposed interval estimator is evaluated on the basis of an extensive Monte Carlo simulation study. The coverage ratio and average width of the proposed confidence interval are compared with certain existing and widely used confidence intervals. The simulation results show that, in general, the proposed interval estimator’s performance is highly effective. For illustrative purposes, three real-life data sets are analyzed, which, to a certain extent, support the findings obtained from the simulation study. Thus, we recommend that practitioners use the robust modified confidence interval for estimating the population mean when the data are generated by a normal or skewed distribution.
On the nonparametric estimation of the conditional hazard estimator in a single functional index
Authors: Gagui Abdelmalek , Chouaf Abdelhak 
Published: October 2022

Abstract
This paper deals with the conditional hazard estimator of a real response where the variable is given a functional random variable (i.e it takes values in an infinite-dimensional space). Specifically, we focus on the functional index model. This approach offers a good compromise between nonparametric and parametric models. The principle aim is to prove the asymptotic normality of the proposed estimator under general conditions and in cases where the variables satisfy the strong mixing dependency. This was achieved by means of the kernel estimator method, based on a single-index structure. Finally, a simulation of our methodology shows that it is efficient for large sample sizes.

Authors: Aijaz Ahmad , Ain S. Qurat ul , Afaq Ahmad , Tripathi Rajnee 
Published: October 2022

Abstract
In this paper, a new Poisson area-biased Ailamujia distribution has been formulated to analyse count data. It was created by combining two distributions: the Poisson and area-biased Ailamujia distributions, using the compounding technique. Several distributional properties of the formulated distribution were studied. Its ageing characteristics were determined and expressed explicitly. A variety of diagrams were used to demonstrate the characteristics of the probability mass function (pmf) and the cumulative distribution function (cdf). The parameter of the developed model was estimated by employing the maximum likelihood estimation approach. Finally, two data sets were used to demonstrate the effectiveness of the investigated distribution.

Intramedullary spinal cord metastasis of clear cell renal carcinoma in a Von Hippel–Lindau patient
Authors: Holanda Tiago S. F. , Lopes Edson 
Published: October 2022

Background:
Intramedullary spinal cord metastasis is uncommon and represents only 0.6% of all spinal tumors. Renal cell carcinoma is even less frequent in this group than in lung and breast cancer. Patients with Von Hippel– Lindau disease (VHLd) present spinal hemangioblastoma more frequently.

Case Description:
A 59-year-old female patient presented with medullary syndrome. There was a previous history of VHLd, with a cerebellar hemangioblastoma resection years ago. The radiological investigation showed a cervical intramedullary solid-cystic lesion. The patient has submitted a tumor resection, and a pathological and immunohistochemistry study confirmed clear cell renal carcinoma metastasis.

Conclusion:
In patients with VHLd, the presence of an intramedullary solid-cystic lesion may not represent always a hemangioblastoma. Other diagnostic possibilities must be evaluated, despite being epidemiologically less frequent. Inside the group of patients with VHLd, only a previous case of intramedullary spinal cord renal cell carcinoma was reported in the literature.
Surgical management of petrous apex cholesteatomas in the pediatric population: A systematic review
Authors: Reardon Taylor , Turnow Morgan , Elston Sidney , Brown Nolan J. , Koller Gretchen M. , Sharma Shelly , Kortz Michael W. , Mohyeldin Ahmed , Fraser Justin F. 
Published: October 2022

Background:
Cholesteatomas are growths of squamous epithelium that can form inside the middle ear and mastoid cavity and damage nearby structures causing hearing loss when located at the petrous apex. The primary goal of petrous apex cholesteatoma resection is gross total removal with tympanoplasty and canal-wall up or canal-wall down tympanomastoidectomy. At present, there is no definitive surgical approach supported by greater than level 4 evidence in the literature to date.

Methods:
A systematic review was conducted utilizing PubMed, Embase, and Scopus databases. Articles were screened and selected to be reviewed in full text. The articles that met inclusion criteria were reviewed for relevant data. Data analysis, means, and standard deviations were calculated using Microsoft Excel.

Results:
After screening, five articles were included in the systematic review. There were a total of eight pediatric patients with nine total cholesteatomas removed. Conductive hearing loss was the most common (77%) presenting symptom. Perforations were noted in seven ears (86%). Recurrence was noted in 50% of patients with an average recurrence rate of 3.5 years (SD = 1.73). Average length of follow-up was 32.6 months (SD = 21.7). Canal-wall up was the most utilized technique (60%) and there were zero noted surgical complications. Five of the seven (71%) patients that experienced hearing loss from perforation noted improved hearing.

Conclusion:
Due to its rarity, diagnostic evaluation and treatment can vary. Further, multi-institutional investigation is necessary to develop population-level management protocols for pediatric patients affected by petrous apex cholesteatomas.
White cord syndrome following posterior decompression and fusion for severe OPLL and an acute traumatic cervical injury – A case report and review of literature
Authors: Dahapute Aditya Anand , Balasubramanian Sai Gautham , Annis Prokopis 
Published: October 2022

Background:
White cord syndrome (WCS) refers to the observation of intramedullary hyperintensity due to edema/ischemia and swelling on postoperative T2-weighted MRI sequences in the setting of unexplained neurological deficits after cervical spinal cord decompression. Pathophysiologically, WCS/reperfusion injury (RPI) occurs due to oxygen derived free radicals as a result of acute reperfusion or direct trauma from blood flow itself. Intraoperative neurophysiologic monitoring (IONM) can give early warning and detect neurologic deficits. Here, we are presenting a case of a patient who had a chronic severe ossification of posterior longitudinal ligament (OPLL) of cervical cord, underwent decompressive surgery, and developed quadriplegia postoperatively without any perceptible iatrogenic cord trauma, documented by IONM and postoperative MRI with classical signs of WCS.

Case Description:
A 63-year-old male presented with low velocity fall at home followed by quadriparesis. X-ray images on presentation showed C6 fracture and local kyphosis. MRI images showed that there is marked spinal canal stenosis from C2 down to C4 due to OPLL with intrinsic signal changes in the cord. On decompression, motor-evoked potential signals were not present below C4. Immediate postoperative MRI was done to rule out any compressive pathology. MRI showed T2 hyperintensity of the cord at C3 level with cord edema. No evidence of epidural hematoma or other compressive lesion was found and the diagnosis of WCS/RPI was established.

Conclusion:
WCS is essentially a diagnosis of exclusion. Very rarely, patients sustain severe/new neurological deficits postoperatively attributed to WCS. Unless, this is confirmed postoperatively with classical MRI signs of intramedullary hyperintensity, the diagnosis should not be invoked.
Support and guide performance comparison of balloon guide catheters
Authors: Matsumoto Takashi , Takeuchi Masataka , Uyama Atsushi , Konishi Yoshifumi , Iwabuchi Satoshi 
Published: October 2022

Background:
Several types of balloon guide catheters (BGCs) are used in mechanical thrombus retrieval. However, direct comparisons of their supporting and guiding performance have not been reported. We compared the supporting and guiding performance of the Branchor, Flowgate, and Optimo BGCs using a type 3 aorta artificial vascular model.

Methods:
An inner catheter was pushed into the artificial vascular model using a linear actuator for the supporting performance evaluation. A previously placed BGC in the internal carotid artery was then intentionally caused to slip. Supporting performance was evaluated by measuring the distance the BGC slipped and generated maximum resistance during Inner catheter insertion. For the guiding performance experiment, a linear actuator was used to guide the BGC into the internal carotid artery of the artificial vessel model. The guiding performance was evaluated by measuring the distance reached by the BGC, maximum resistance generated during insertion of the guiding catheter, and distance the inner catheter slipped. Each experiment was replicated 5 times.

Results:
No statistically significant differences were observed in the results of the five supporting performance experiments. However, the results of the first and second experiments suggested that the Optimo offers better supporting performance. In the guiding performance experiment, significant differences were observed, suggesting that the Branchor and Flowgate have superior guiding performance in comparison with the Optimo.

Conclusion:
The Optimo offered superior supporting performance, while the Branchor and Flowgate showed better guiding performance than the Optimo.
Infratentorial retroclival and tentorial subdural hematoma from posterior communicating artery aneurysm rupture: A case report and systematic review of literature
Authors: Saway Brian Fabian , Fielder Tristan , Alshareef Mohammed Abdul , Rafka Habib Emil , Sattur Mithun , Lena Jonathan 
Published: October 2022

Background:
The objective of this systematic review is to evaluate the pathogenesis, clinical course, and prognosis of patients who suffer from aneurysm rupture, leading to subdural hematoma (SDH) of the infratentorial space without associated subarachnoid hemorrhage (SAH).

Methods:
Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a literature review was conducted in PubMed and Scopus electronic databases for relevant published cases of aneurysmal SDH (AnSDH) of the infratentorial compartment without associated SAH. The presentation, treatment, clinical course, and outcome of identified cases are compiled. In addition, a patient suffering from an infratentorial SDH following aneurysm rupture is presented with an illustrative case.

Results:
Three articles were identified and met inclusion criteria. All cases occurred from ruptured posterior communicating artery aneurysms. All patients arrived with a Hunt and Hess classification of 2 or less. Only one case was managed with operative aneurysm clipping and hematoma evacuation while the other three cases were managed endovascularly. There were no reported postoperative complications, vasospasm, or seizures reported. All patients had a final Modified Rankin score of 3 or less at last reported follow-up.

Conclusion:
Infratentorial AnSDH without associated SAH is an etiology rarely reported in the literature. Here, we present a case report and systematic review demonstrating a relatively benign clinical course and outcome compared to report aneurysm rupture associated with SAH or mixed SAH and SDH. Moreover, there appear to be lower rates of vasospasm and improved outcomes in patients with isolated AnSDH compared to the literature aneurysmal SAH rates.
Right-sided aortic arch with complex anomalies presented with transient ischemic attack
Authors: Al-Khazaali Younus M. , Hummadi Noor A. , Ismail Mustafa , Al-Waely Noor K. , Ahmed Fatimah O. , Hoz Samer S. , Andaluz Norberto 
Published: October 2022

Background:
The right-sided aortic arch (RAA) is an uncommon anatomical anomaly found in <0.1% of the adult population. In this article, we report a case of RAA anomaly with an aberrant left subclavian artery (ALSA) and Kommerell’s diverticulum associated with aneurysmal dilation of the ascending aorta, left carotid artery (CCA) stenosis, and pancake kidney presented with a transient ischemic attack (TIA). To the best of our knowledge, this is the first case in the literature that discusses such associations, especially in a symptomatic patient with neurological rather than tracheaesophageal symptoms and in the absence of the steal phenomenon.

Case Description:
A 52-year-old male, with a history of recurrent multiple TIAs, presented immediately after the onset of blurred vision and left-sided weakness. The initial diagnostic cerebral angiogram revealed a left CCA stenosis of <30%, with normal posterior circulation vasculature. The diagnosis of RAA was made with computed tomography angiography (CTA) of the thoracic and abdominal aorta, which revealed Type 2 RAA, with ALSA, which had a bullous dilatation at its origin that suggests Kommerell’s diverticulum. Another two findings on CTA were a persistent left-sided superior vena cava that ended in the coronary sinus and a single pelvic fused renal mass (Pancake kidney).

Conclusion:
We presented an extremely rare case of RAA with ALSA associated with a group of extra rare anomalies. Understanding the anatomical variants of RAA and its characteristics is critical to improving the management and follow-up of patients with such anomalies.
