A 38-year male presented with severe low back pain radiating towards right lower limb which was progressively increasing with decrease in motor power of the ipsilateral ankle dorsiflexion and toe extension. Magnetic Resonance study with gadolinium suggested dorsal epidural migration of the extruded disc at L4-L5 level compressing the thecal sac, which mimics the differential diagnosis epidural abscess, epidural hematoma, synovial cyst and extradural space-occupying lesion. Open lumbar discectomy was done, and the large, herniated disc was found dorsal to the thecal sac adhering dura mater, which was removed meticulously and the patient was symptomatically better postoperatively. The power of his lower limb gradually increased by physiotherapy in subsequent follow-up.

An unexpected cause of intractable dysphagia after 20 years following cervical spine instrumentation using bone cement alone: a case report.
Ann Med Surg (Lond)

Department of Neurosurgery, Tribhuvan University Teaching Hospital, Maharajgunj, Kathmandu, Nepal.
Introduction And Importance: Postoperative dysphagia following anterior cervical discectomy fusion (ACDF) for cervical disc herniation is still poorly understood. Dysphagia after anterior spinal cervical approach is mild and transient. Here, the authors present a rare case suffering with severe progressive dysphagia for over 1 year after 20 years of ACDF due to expulsed bone cement abutting the esophagus which was successfully removed after reoperation.

Introduction: This study evaluated and compared the amount of apically extruded debris, unprepared wall surface areas, and dentinal crack formation resulting from root canal preparation using ProTaper Next (PTN), ProTaper Ultimate (PTU), and R-Motion (RM) file systems.
Methods: Forty-five palatal roots of maxillary first molars were shortened to a uniform length of 12 mm. The samples were divided randomly into 3 groups (n = 15/group) to be prepared using either PTN, PTU, and RM file systems.
Association of optic disc drusen and small scleral canals - A systematic review and meta-analysis.
Eye (Lond)

Department of Ophthalmology, Necker-Enfants malades University Hospital, AP-HP, Paris, France.
The pathophysiology of optic disc drusen (ODD) has long been discussed. According to one leading theory, they develop from calcified mitochondria extruded from axons compressed by an unusually small scleral canal. To examine this hypothesis, we conducted a systematic review and meta-analysis evaluating the scleral canal size in patients with ODD (PO) in comparison to healthy subjects (HS).

This study presents a novel approach to the development of high-performance supercapacitors through 3D printing technology. We synthesized a composite material consisting of silver-doped reduced graphene oxide (rGO) and dodecylbenzenesulfonic acid (DBSA)-doped polyaniline (PANI), which was further blended with polylactic acid (PLA) for additive manufacturing. The composite was extruded into filaments and printed into circular disc electrodes using fused deposition modeling (FDM).

Article Synopsis
- Typhoid fever is primarily spread through contaminated food and water, with poor sanitation being a significant factor, and the bacteria responsible have developed resistance to many antibiotics, complicating treatment efforts.
- This study collected 80 clinical isolates to investigate the molecular basis of fluoroquinolone resistance, confirming that 60% of these isolates were resistant to ciprofloxacin, a common treatment.
- Key mutations were found in specific bacterial genes, affecting drug binding and resistance mechanisms, indicating a need for further experimental studies to create effective treatments for antibiotic-resistant typhoid.
