Pediatric penetrating brain injuries with intact neurological function: Two case reports of a pencil and a toy wheel encounter.

Accidental injuries in the pediatric population are common. The response to injury also differs owing to anatomical and physiological differences in children. While such injuries carry a risk of lifelong morbidity, some cases may follow a benign course despite their distressing appearance. We report two cases of accidentally incurred penetrating trauma in the pediatric population with unusual objects, including a pencil and a toy wheel. Despite their intracranial extension, neither of the patients exhibited any discernible neurological deficits. Penetrating brain injuries require early removal and meticulous perioperative care to minimize the risk of long-term adverse neurological events in children.

Letter to editor: Beyond nimodipine: advanced neuroprotection strategies for aneurysmal subarachnoid hemorrhage vasospasm and delayed cerebral ischemia.

This critique discusses neuroprotective strategies for aneurysmal subarachnoid hemorrhage (SAH), excluding Nimodipine, emphasizing alternatives like verapamil, albumin, and cilostazol. While these options show potential, their efficacy lacks robust confirmation from randomized controlled trials (RCTs), relying mainly on observational studies and small trials. The letter underscores the need for comprehensive safety assessments and long-term outcome studies to enhance practical application. Highlighting ongoing trials and emerging therapies like clazosentan and TAK-044, it advocates for future research directions focused on large-scale RCTs and combination therapies, such as cilostazol and Nimodipine, which have demonstrated synergistic benefits in reducing delayed cerebral ischemia (DCI) and improving patient outcomes.

Letter to Editor: Cystic vestibular schwannoma - a subgroup analysis from a comparative study between radiosurgery and microsurgery.

This letter evaluates the recent study on the management of cystic vestibular schwannomas (VS) compared to solid VS, focusing on the clinical outcomes of surgery (SURGERY) and radiosurgery (SRS). The study offers significant insights into the differences between these tumor types, emphasizing the challenges posed by cystic VS, including rapid growth, enhanced peritumoral adhesion, and worse post-operative facial nerve outcomes. Notably, cystic VS are associated with higher recurrence rates and poorer preoperative status. The study also highlights lower gross total resection (GTR) rates and poorer long-term tumor control in cystic VS. While SRS shows high rates of functional preservation, it is less effective in ensuring recurrence-free survival in cystic VS compared to solid VS, suggesting surgery may be preferable for achieving the best long-term outcomes, particularly when safe maximal resection is possible. However, the study's retrospective design and limited sample size, along with the lack of standardized follow-up protocols, may impact the generalizability of the findings. Future research should focus on prospective, multicenter studies with standardized protocols to develop evidence-based guidelines for managing cystic VS. Innovative techniques, such as advanced imaging and minimally invasive surgical approaches, may further improve diagnostic accuracy and treatment efficacy. This study underscores the complexities of managing cystic VS and the need for tailored treatment strategies.

Letter to editor: Exploring the influence of nasal morbidity on quality of life following endoscopic endonasal skull base surgery: a retrospective cohort study of 95 patients.

This retrospective cohort study evaluated the impact of nasal morbidity on quality of life following endoscopic endonasal skull base surgery (EESBS) using the Sino-Nasal Outcome Test-22 (SNOT-22) and Anterior Skull Base Inventory (ASB-12). While 89% of patients found the nasal morbidity acceptable given the surgical goals, limitations include the study's retrospective nature, specific focus on certain pathologies, and a short follow-up period of up to 6 months. Future research should utilize comprehensive outcome assessment tools and consider broader patient populations to enhance study validity and applicability.

Letter to editor: Serum concentration-guided intravenous magnesium sulfate administration for neuroprotection in patients with aneurysmal subarachnoid hemorrhage: A retrospective evaluation of a 12-year single-center experience.

This critique examines a 12-year retrospective study on serum magnesium concentration-guided administration of magnesium sulfate in 548 patients with aneurysmal subarachnoid hemorrhage (aSAH). The study reported that maintaining serum magnesium levels between 2 and 2.5 mmol/L reduced rates of delayed cerebral infarction and improved clinical outcomes. However, limitations due to its retrospective nature, single-center design, and unequal treatment group sizes may affect generalizability. Future multicentric randomized controlled trials are recommended to validate these findings and refine magnesium dosing strategies for aSAH treatment.

Impact of biologically effective dose on tremor decrease after stereotactic radiosurgical thalamotomy for essential tremor: a retrospective longitudinal analysis.

This letter to the editor critiques a recent study evaluating the role of biologically effective dose (BED) in stereotactic radiosurgical thalamotomy for essential tremor (ET). The study, conducted retrospectively on 78 ET patients, demonstrates a significant correlation between BED and tremor improvement post-SRS. Moreover, the study suggests adjusting the prescribed dose rather than changing cobalt-60 sources to maintain treatment efficacy while minimizing toxicity. This suggestion aligns with previous research indicating an annual decrease in BED due to cobalt-60 decay. The letter emphasizes the importance of considering BED and cobalt-60 decay in optimizing treatment outcomes for ET patients undergoing stereotactic radiosurgery. Further research is recommended to explore innovative techniques for dose modulation in response to cobalt-60 decay and validate findings in larger cohorts.

Pancreatic adenocarcinoma of the tail-Unveiling a rare presentation with venous thrombosis: A case report and literature review.

Pancreatic cancer is a silent and lethal adversary that often conceals its presence until advanced stages. This report elucidates a distinctive case of a 46-year-old patient with pancreatic tail adenocarcinoma presenting with venous thrombosis, a rare manifestation. The patient's symptoms included severe left leg pain, swelling, and redness, accompanied by weight loss and decreased appetite. Laboratory findings indicated a prothrombotic state, whereas imaging revealed a substantial mass on the tail of the pancreas with hepatic metastasis. Elevated cancer antigen 19-9 and carcinoembryonic antigen supported the diagnosis which was confirmed by a liver biopsy. This case underscores the diagnostic challenges posed by pancreatic cancer, particularly in the tail, emphasizing the need for early detection. The intricate interplay between metastasis and thrombosis complicates the clinical landscape, requiring a comprehensive approach to management.

Letter to editor: Exploring complications following cranioplasty after decompressive hemicraniectomy: A retrospective bicenter assessment of autologous, PMMA and CAD implants.

This study presents a critical analysis of complications following cranioplasty (CP) after decompressive hemicraniectomy, focusing on autologous, polymethylmethacrylate (PMMA), and computer-aided design (CAD) implants. The analysis encompasses a retrospective bicenter assessment, evaluating factors influencing surgical outcomes and emphasizing the significance of material selection in minimizing postoperative complications. The study's comprehensive examination of complication rates associated with various implant materials contributes significantly to understanding CP outcomes. While polymethylmethacrylate (PMMA) and autologous bone flaps (ABFs) exhibited higher rates of surgical site infection (SSI) and explantation, a meta-analysis revealed a contrasting lower infection rate for polyether ether ketone (PEEK) implants. The study underscores the critical role of material selection in mitigating postoperative complications. Despite its strengths, the study's retrospective design, reliance on data from two centers, and limited sample size pose limitations. Future research should prioritize prospective, multicenter studies with standardized protocols to enhance diagnostic accuracy and treatment efficacy in CP procedures.

Exploring the link between long-term intrauterine contraceptive device usage and abdominal actinomycosis in a middle-aged female: A case report.

Actinomycosis is a rare, chronic, and suppurative disease caused by Actinomyces species, which are filamentous, obligate, Gram-positive bacteria. This report presents a case of anterior abdominal actinomycosis in a 40-year-old female with a history of intrauterine contraceptive device placement. The patient presented with severe abdominal pain, an abdominal mass, low-grade fever, and weight loss. Imaging studies revealed thickening of the left rectus abdominis muscle and pericolic fat stranding. An exploratory laparotomy confirmed dense adhesions from the transverse colon and omentum to the abdominal wall with a purulent discharge. Resection of the affected colon segment and primary anastomosis were performed. Histopathological examination revealed characteristic colonies of Actinomyces within abscesses, confirming the diagnosis of actinomycosis. The patient received appropriate antibiotic therapy and showed improvement. This case highlights the rare occurrence of abdominal wall actinomycosis associated with an intrauterine contraceptive device and emphasizes the importance of considering actinomycosis in the differential diagnosis of abdominal pathologies. Thus, medical history related to intrauterine contraceptive device use should be regarded as in differentials if a patient presents vague abdominal mass and pain, and small details in history should be emphasized and looked upon so that a timely decision can be made for the betterment of the patient.

Self-inflicted penetrating brain injuries with preserved neurological function: a case series.

BACKGROUND: Penetrating trauma to the brain is a rare mode of self-harm in individuals with depressive psychosis. It may have variable presentations ranging from intact neurological status to non-survivable damage and the subjects may be surprisingly apathetic to pain. It is even unusual for such an injury to have an excellent prognosis despite coming late to clinical attention. CASE PRESENTATIONS: We report two cases of patients with psychotic depression who attempted suicide by hammering nails into their heads. On imaging, deep penetration within the brain parenchyma was noted; however, neither case had any neurological deficit or symptoms attributable to brain trauma. CONCLUSIONS: Self-inflicted penetrating brain injuries with peculiar objects such as nails are rarely encountered in practice. They need prompt management for their removal and addressing the underlying mental health illnesses.
