A number of parasitic infections can involve the central nervous system of which neurocysticercosis (NCC) is the most common one in developing countries. Most often the brain is involved, spine and spinal cord involvement is very rare and intramedullary involvement is rarer still. Here, we report a 30-year-old male patient, with intramedullary NCC of dorsal spinal cord.

Study design: Prospective study. Objective: The aim of this study is to visualize the morphology of a lumbar herniated disc and Kambin’s triangle in three dimensions (3D) based on preoperative CT/MRI fusion images. Methods: CT/MRI fusion images of 23 patients (10 males and 13 females; mean age 58.2 years) were used to evaluate Kambin’s triangle, which is created between the superior articular process (SAP), exiting nerve root (ENR), inferiorly by the superior endplate of the lower lumbar vertebra and dural canal medially at 60 degree and 45 degree endoscopic approach angles. The percentage of the safe usage of transforaminal endoscopic approach was evaluated to utilize a 5 mm dilater without partial facet resection in the fusion image. The 3D lumbar nerve root sleeve angulation (3DNRA), which is the angle between the axis of the thecal sac and the nerve root sleeve, was calculated. The herniated discs were also visualized in the CT/MRI fusion image. Results: The 3DNRA became smaller from L2 to S1. The L2 3DNRA was statistically larger than those of the other root, and the S1 3DNRA was significantly smaller than the others (p < 0.05). (L2, 41.0°; L3, 35.6°; L4, 36.4°; L5, 33.9°; and S1, 23.2°). The SAP-ENR distance at 60° was greatest at L4/5 (5.9 mm). Possible needle passages at 60° to each disc level were 89.1% at L2/3, 87.0% at L3/4 and 84.8% at L4/5. However, the safe 5 mm dilater passage at 60° without bony resection to each disc level were 8.7% at L2/3, 28.3% at L3/4 and 37.0% at L4/5. The 60° corridor at L2/3 was the narrowest (p < 0.01). All herniated discs were visualized in the fusion image and the root compression site was clearly demonstrated especially with foraminal/extraforaminal herniations. Conclusion: The 3D lumbar CT/MRI fusion image enabled a combined nerve-bony assessment of Kambin’s triangle and herniated disc. A fully endoscopic 5 mm dilater may retract the exiting nerve root in more than 60% of total cases. This new imaging technique could prove to be very useful for the safety of endoscopic lumbar disc surgery.

Aims: After initial primary repair by inexperienced hands for the spectrum of pathological conditions in spinal dysraphism (SD), a few percentage of patients present with recurrent symptoms and worsening neurological status especially when primarily pathology is not identified and dealt properly. When the primary intradural tethering element is left untouched, worsening of symptoms is common. In this retrospective study, we tried to analyze the symptomatology, functional outcome at 1–2 months after the second surgery and associated complications. Subjects and Methods: All patients underwent second surgery at author’s institution. Pre and post-operative data were evaluated using Necker –Enfants Malades (NEM) neurological and modified Hoffer ambulatory scale. Results: The main presenting complaints were bladder incontinence and limb weakness. Preoperative mean scores for motor and bladder were 3.56 and 2.78 out of 5, 2.67 out of 4, and 2.11 out of 3 for bowel and sensory function, respectively. Postoperative mean score for motor, sensory, bladder, and bowel function revealed good neurological improvement. Statistically neurological improvement in bladder and bowel function was significant. More than 60% of patients had normal ambulation at follow-up. Conclusions: Patients presenting with recurrent symptoms in an operated case of SD need to be investigated, cause of recurrence has to be identified, and if needed repeat surgery is recommended at the earliest. Long-standing neurological deficits can potentially improve, especially bladder and bowel function which gives a good quality of life to the patients. Furthermore, we want to stress the fact that since it is an intradural pathology, these cases should be operated by experienced neurosurgeons, and this fact should be made aware among referring doctors.

Study design :Technical note. Objectives : To present a new unilateral biportal endoscopic technique for lumbar disc herniation without C-arm . Background : Lumbar disc herniation requires surgical intervention when conservative methods fail. Shifts towards minimally invasive percutaneous endoscopic lumbar discectomy, including uniportal and biportal approaches, have been hindered by challenges such as steep learning curves and reliance on radiation-intensive C-arm guidance. Our study introduces the use of standard intraoperative navigation in unilateral biportal endoscopy (UBE) to reduce radiation exposure and increase surgical acuracy. Materials and Methods : A 24-year-old man with low back and bilateral leg pain with gait disturbance was referred to our hospital. He had have conservative treatment for 12 months in another hospital before admission. However, the conservative treatment did not work for him. He had low back pain (VAS 4/10) and bilateral leg pain (VAS 8/10), muscle waekness of bilateral legs (Manual muscle testing ;MMT of extensor hullusis longs 4 4), and numbness of bilateral lower leg. Preoperative lumbar MRI showed L4/5 large central disc herniation. Results: He underwent C-arm free unilateral biportal endoscopic discectomy under the guidance of O-arm navigation. The patient was successfully treated surgically. Postoperative lumbar MRI showed good decompression of dural sac and bilateral L5 nerve roots. MMT and sensory function of both leg had recovered fully on final follow-up at one year. Conclusions/Level of Evidence: The new unilateral biportal endoscopic technique under navigation guidance is useful technique for lumbar disc herniation. This innovative technique proved to be safe, accurate, and minimized radiation exposure for surgeons for the treatment of lumbar intervertebral disc herniation. Level V.

Objectives: HIV/AIDS education is one of the most important topics taught during medical training; conventional lecture-based methods often lack in helping students understand its emotional, ethical, and social complexities. To handle these aspects, alternative/additional methods like cinemeducation could help as an innovative approach where movies, along with narrative media, would help the students to better engage and understand the topic through an empathetic learning experience, thus helping to improve both knowledge retention and bring about attitudinal change. Thus, this study was conducted to compare the effectiveness of cinemeducation versus traditional didactic lectures in improving HIV/AIDS-related knowledge, reducing stigma and enhancing clinical confidence among undergraduate medical students. Material and Methods: A quasi-experimental study was conducted among 180 second-phase MBBS students. Participants were divided into two groups (n = 90 each). Group A received a film-based cinemeducation intervention, and Group B underwent a traditional lecture on HIV/AIDS. Pre- and post-test questionnaires were used to assess knowledge, attitudes, and clinical confidence. Statistical analyses: paired and independent t-tests were performed using SPSS version 20. Results: Both groups showed statistically significant improvements in knowledge and attitudes with p <0.001. However, the cinemeducation group demonstrated greater mean score improvement (pre: 10.1 ± 2.4; post: 14.6 ± 1.6; Δ = +4.5) compared to the lecture group (pre: 10.2 ± 2.3; post: 13.8 ± 1.9; Δ = +3.6). Cinemeducation was more effective in enhancing understanding of complex concepts such as U=U and confidentiality responsibilities, and also helped in reducing discomfort in treating PLHIV. Following this session, attitudinal gains were also seen among the participants, which were reflected in increased empathy, reduced stigma, and improved ethical awareness. Conclusion: Cinemeducation significantly enhances cognitive and affective learning outcomes in comparison to traditional lectures. Being a story-based approach, it helps in emotionally engagement of the students, thus helping to clear misconceptions, reduce stigma, and build a more professional attitude toward HIV/AIDS care. Integrating cinemeducation into medical curricula may help bridge the gap between theoretical knowledge and humane clinical practice.
