Objective:
Tracheostomy is a necessary procedure for patients admitted to the neurosurgery intensive care unit (ICU) with severe brain injury, because mechanical ventilation must be maintained for a long time following neurologic failure. The purpose of this study was to compare conventional surgical tracheostomy (CST) and percutaneous dilatational tracheostomy (PDT) performed at the bedside in critically ill neurosurgery patients requiring tracheostomy to determine which procedure has comparative advantages.
Methods:
This retprospective study was conducted between January 2019 and December 2020. PDT was performed on 52 patients and CST was performed on 44 patients. The baseline characteristics, procedural characteristics, and clinical outcomes were recorded.
Results:
The mean operative time in the CST group was 25.5±6.5 minutes and that in the PDT group was 15.1±2.5 minutes; the difference was statistically significant (p<0.01). Four patients in the CST group and none in the PDT group experienced bleeding requiring transfusion. However, there was no significant difference in total ICU mortality or length of hospital stay. There were no statistical differences in the individual complication categories between the 2 study groups.
Conclusion
There were fewer procedure-induced complications among patients receiving PDT than among those receiving CST. In addition, the treatment time for PDT was shorter than that for CST treatment.

Persistent primitive trigeminal artery (PPTA) is the most common carotid-basilar anastomosis; on the other hand, persistent primitive otic artery (PPOA) is extremely rare. PPTA is often misdiagnosed as PPOA on cerebral angiography. We present a case of PPTA that mimicked PPOA on cerebral angiography. We further describe the utility of brain computed tomography angiography for differential diagnosis of PPTA from PPOA, together with a review of previous literature.

This study was performed to radiographically examine the prevalence of aspiration sites and to evaluate their atomical correlation with the bronchial pattens. Ten healthy beagle dogs were repeatedly radiographed, at weekly intervals, in the left and right lateral, ventrodorsal (VD) and dorsoventral (DV) positions. Three mililiters of iohexol distilled with same volume of saline was infused into the tracheal inlet. Which lung lobe was aspirated was decided upon by the presence of a significant alveolar pattern due to the contrast medium. Alveolar patterns were identified at the left (100%) and right cranial lung lobes (77%) with the dogs in dependant lateral recumbency, at the right caudal lung lobe (71%) with the dogs in VD recumbency and at the right middle lung lobe (59%) with the dogs in DV recumbency, respectively. The anatomical correlation was evaluated by performing computed tomography. The right principal bronchus (165.8 +/- 1.6 degrees) was more straightly bifurcated than was the left principal bronchus (142.7 +/- 1.8 degrees, p < 0.01). In VD position, the right side lung had a greater opertunity to become aspirated. The ventrally positioned right middle lobar bronchial origin was more easily to be aspirated the other laterally positioned ones. We think that these anatomical characteristics can be one of the causes for aspiration pneumonia to occur more frequently in the right side lung.

PURPOSE: Divided end-loop colostomy is recommended in some cases of unresectable rectal cancer or anal incontinence, because a conventional loop colostomy is difficult to managing due to bulky stoma volume for a long period. In such case of the divided end-loop colostomy, severe inflammation may occur at the stoma site by poor conditions of the patient so that cause to be retracted or detached, and distal loop may be disrupted. To avoid these problems, we designed subtotally divided end-loop colostomy and studied its clinical effectiveness retrospectively. METHODS: About a 3 cm diameter, round skin incision as presumed colostomy size was made at the left lower abdomen, and entered the abdominal cavity by splitting the rectus muscle fibers. The caudal side of colon can be identified by confirming the fusioned taenia at the rectosigmoid colon level. After pulling out the colonic loop, the distal colon far from the lesion was subtotally divided by a GIA staple or manual suture, which cut obliquely 80% or 90% from the antimesenteric side of the distal loop while maintaining the 10% or 20% mesenteric side of the colonic loop. Then an end-loop colostomy is matured with a small fistularization of the distal loop as the undivided mesenteric side of colon. RESULTS: In 8 cases, subtotally divided colonic loop using a GIA staple. But in 9 cases, divided manually because of makedly thickened, edematous colonic wall resulting from prolonged obstruction. There were several mild complications, i.e. transient dermatitis in 5 cases, transient bulky stoma due to edema in 4 cases, mild retraction of stoma in 2 cases, and mild prolapse of stoma in 1 case. There were no major functional abnormalities during the follow-up period. CONCLUSIONS: Although we need to get further clinical experiences, the subtotally divided end-loop colostomy seems to be a useful alternative surgical procedure for unresectable rectal cancer.

PURPOSE: Fever is one of the most common symptoms in children visiting the emergency department. When oral antipyretics use is limited, IV antipyretics may be necessary for control of fever. In this study, we examined the current status of use and antipyretic effect of propacetamol, a precursor of acetaminophen, in fever management for children of age younger than 15 in an emergency center. METHODS: We reviewed medical records of 101 patients who were prescribed IV propacetamol from September 1st to December 31st in 2013. Among these patients, 59 children received propacetamol via intravenous injection for control of fever. We investigated variable data including age, sex, weight, chief complaint, reason for use of intravenous propacetamol, history of liver disease, and body temperature before the injection. In addition, to examine the antipyretic efficacy of IV propacetamol, we thoroughly investigated administration dose, number of injections, use of other antipyretics, other antipyretic therapy (ex. like tepid massage or ice bag), fever clearance time, etc. RESULTS: Intravenous propacetamol at a dose of 26.16 mg/kg was used in 59 patients and fever was controlled under 38degrees C within 2 hours in 39 patients (66.1%). Fever was relieved under 38degrees C within 4 hours or general condition was improved in 49 patients (83.0%). CONCLUSION: In this study, we examined the antipyretic efficacy of intravenous propacetamol in management of fever for children younger than 15 years of age in an emergency center. Optimized uses of intravenous propacetamol according to age and weight were effective for pediatric patients with fever who cannot swallow oral medications.

Arthroscopic treatment has been reported to provide effective improvement of ankle function when used in treatment of small osteochondral lesion of talus; however, favorable long-term results have been less predictable for large osteochondral lesion of talus. In cases in which primary arthroscopic treatment fails, the decision regarding which subsequent technique to choose has become increasingly difficult, as good clinical outcomes may be unlikely for such patients irrespective of the surgical technique used. Redomicrofracture should be used judiciously for treatment of osteochondral lesion of talus in which arthroscopic treatment has failed.

OBJECTIVE: The objective of this study was to determine the efficiency and safety of Y configuration stent-assisted coiling with double-closed stents for wide-necked intracranial aneurysms located at arterial bifurcations thorough analysis of a multicenter case series. MATERIALS AND METHODS: A retrospective chart review was done on 10 patients who underwent endovascular treatment of wide-necked intracranial aneurysms with Y-configuration stent-assisted coil embolization in three centers from August 2011 to March 2014. The degree of aneurysmal occlusion was assessed using the Raymond scale. Clinical outcomes were assessed before operation, at discharge, and at the last follow-up visit using the Glasgow outcome scale. RESULTS: The 10 patients included 6 females and 4 males with a mean age of 58.6 years. Indications for treatment included 6 unruptured intracranial aneurysms and 4 ruptured intracranial aneurysms. Five aneurysms were located at the basilar artery bifurcation, four aneurysms were located in an anterior communicating artery, and one aneurysm was in the pericallosal artery. The mean size of the 10 aneurysms was 9.7 mm. All aneurysms had a dome-to-neck ratio of < 1.5 (mean, 0.89). Immediate complications included one thromboembolic event out of the 10 cases. Immediate posttreatment angiograms showed complete occlusion in 1 aneurysm and residual necks in 9 aneurysms. Follow-up results showed 8 complete occlusions and 2 residual necks. No delayed complications were observed during the follow-up period (mean: 20 months). CONCLUSION: Y configuration using double-closed cell stents is feasible and safe in selected patients. This method is an acceptable option for managing complex wide-necked bifurcations.

Herpes simplex virus type 2 (HSV2) meningitis primarily develops during or following a primary genital HSV2 infection that was acquired from sexual contact or through the birth canal during delivery from mother. We describe a 15 year old virgin without history of previous herpes simplex infection who developed 2 episodes of HSV2 meningitis. Although recurrent meningitis due to HSV is primarily seen in young or sexually active adults. HSV2 meningitis should be in the differential diagnosis of recurrent meningitis in adolescent patients.

OBJECTIVE: The aim of this study was to evaluate the safety and efficacy of stent-assisted coil embolization using only a glycoprotein IIb/IIIa inhibitor (tirofiban). MATERIALS AND METHODS: We retrospectively reviewed patients with a subarachnoid hemorrhage due to ruptured wide-necked intracranial aneurysms who were treated by stent-assisted coil embolization. In all patients, the glycoprotein IIb/IIIa inhibitor tirofiban was administered just before stent deployment. Electronic medical records for these patients were reviewed for peri-procedural complications and extra-ventricular drainage catheter related hemorrhage, as well as Glasgow outcome scale (GOS) at discharge, 3 months, and 6 months follow-up were recorded. RESULTS: Fifty-one aneurysms in 50 patients were treated. The mean patient age was 64.9 years. Eighteen patients (36%) received a World Federation of Neurosurgical Societies grade of 4 or 5. The mean aneurysm size was 9.48 mm and mean dome-to-neck ratio was 1.06. No intraoperative aneurysm ruptures occurred, although five (10%) episodes of asymptomatic stent thrombosis did occur. Three patients experienced a delayed thrombo-embolic event and two a delayed hemorrhagic event. Immediate radiologic assessment indicated a complete occlusion in 29 patients, a residual neck in 19, and a residual sac in 3. Four patients (8%) died. Sixteen patients (32%) experienced a poor GOS (< 4). Two aneurysms were recanalized during the follow-up period (mean, 19 months for clinical and 18 months for angiographic follow-up). CONCLUSION: Treatment of ruptured wide-necked intracranial aneurysms via stent-assisted coil embolization with a glycoprotein IIb/IIIa inhibitor alone was found to be relatively safe and efficient.
