Influence of Fluorine Replacing on Nonbonding Interactions inside Picked Para-Halogeno Anilines.
However, it continues to be a rare and difficult disease to diagnose and is often confused with a neoplastic process. The 99mTc-UBI 29-41 bone SPECT/CT scan could be an auxiliary noninvasive diagnostic alternative and a follow-up method for these patients.
Neurosurgical patients with stroke, trauma, and brain tumors can be among the victims of the COVID-19 pandemic in developing countries, which need to be managed efficiently.

This is an overview of neurosurgical nurses' challenges and strategies in the current COVID-19 pandemic environment in developing countries.

Here, we reviewed the unique challenges of providing neurosurgical nursing services during the COVID-19 pandemic in developing countries. selleck inhibitor We address specific issues such as transferring neurosurgical patients, allocating medical supplies, prioritizing neurosurgical services, COVID-19 testing protocols, and patient triage (emergent vs. urgent vs. delayed surgery). Teleconsultation, telenursing services for outpatient treatment, follow-up and virtual teaching strategies associated with neurosurgical nursing are discussed.

Neurosurgical nursing during the COVID-19 pandemic in developing countries requires transparent planning, implementation, and careful consideration of various telemedicine strategies.

Tubercular atlantoaxial, rotary dislocation warranting fixation (AARF) is an extremely rare event.

AARF was suspected in a 23-year-old female with painful torticollis. When diagnostic studies documented unilateral destruction of the left lateral mass of the atlas, she underwent removal of the lateral mass, reduction of the deformity, and C1-C2 fusion/reconstruction utilizing an iliac bone graft. Laboratory tests and the pathologic surveys were all consistent with the diagnosis of underlying tuberculosis.

We present a case of tubercular atlantoaxial, rotary dislocation (AARF) in a patient who warranted C1-C2 decompression, reduction, and fusion.

Sphenoid wing dural arteriovenous fistula (SWDAVF) is rare that is typically fed by middle meningeal artery feeders and that drain through the sphenoparietal sinus or middle cerebral vein. Here, we report a case of SWDAVF treated by coils placed in the venous aneurysm through the contralateral cavernous sinus (CS).

A 37-year-old woman was admitted to our hospital with headache and bilateral oculomotor nerve palsy. Magnetic resonance images and an angiogram showed a venous aneurysm in the right middle cranial fossa. A DAVF, consisting of two main feeders, was diagnosed based on the angiogram findings. The fistula drained into the left inferior petrosal sinus (IPS) through the left CS and right IPS. Given the remarkable extent of venous ectasia together with the headache and right abducens nerve paralysis, endovascular treatment was initiated. A transvenous approach through the right IPS was not feasible, as it is strenuous to insert the microcatheter into the right IPS. Thus, we tried an approach through the left IPS. The venous aneurysm was embolized with coils. The postoperative course was uneventful, and postoperative cerebral angiography confirmed disappearance of the fistula.

A SWDAVF is extremely rare. In our case, since the AVF drained into the contralateral CS, contralateral ocular symptoms occurred. Endovascular occlusion of the venous aneurysm and fistula was achieved through a transvenous approach.

Due to its rarity, surgical treatments for a complete fifth lumbar osteoporotic vertebral burst fracture (L5 OVBF) have yet to be well documented as compared to that for osteoporotic vertebral fractures of the thoracolumbar spine. The current case report discusses details of the surgical outcomes following posterior decompression and fusion for a complete L5 OVBF.

Three women, ranging in age from 69 years to 82 years, were surgically treated for a complete L5 OVBF. Two of these patients were being treated for rheumatoid arthritis. Surgery was performed using the L5 shortening osteotomy or vertebroplasty, with one- or two-level posterior lumbar interbody fusion, and posterior spinal fixation for the L2 or L3 to the pelvis. Although the spinal alignment parameters, which included lumbar lordosis (LL), pelvic incidence-lumbar lordosis, T1 pelvic angle, and sagittal vertical axis, were better as compared to that observed before the surgery, these worsened at the final follow-up due to clinical fractures that occurred at the adjacent vertebral body and proximal junctional kyphosis. Compared to preoperative Japanese Orthopaedic Association (JOA) scores, postoperative JOA scores were improved and maintained at the final follow-up.

Posterior surgery of a complete L5 OVBF led to improvement of both the JOA score and spinal alignment after the surgery. Despite a worsening of the spinal alignment parameters, the JOA score was maintained at the final follow-up.

Permanent hearing loss after posterior fossa microvascular decompression (MVD) for typical trigeminal neuralgia (TTN) is one of the possible complications of this procedure. Intraoperative brainstem auditory evoked potentials (BAEPs) are used for monitoring the function of cochlear nerve during cerebellopontine angle (CPA) microsurgery. Level-specific (LS)-CE-Chirp® BAEPs are the most recent evolution of classical click BAEP, performed both in clinical studies and during intraoperative neuromonitoring (IONM) of acoustic pathways during several neurosurgical procedures.

Since February 2016, we routinely use LS-CE-Chirp® BAEPs for monitoring the function of cochlear nerve during CPA surgery, including MVD for trigeminal neuralgia. From September 2011 to December 2018, 71 MVDs for TTN were performed in our department, 47 without IONM of acoustic pathways (Group A), and, from February 2016, 24 with LS-CE-Chirp BAEP (Group B).

Two patients of Group A developed a permanent ipsilateral anacusia after MVD. In Group B, we did not observe any permanent acoustic deficit after surgery.
