Electro-nape-acupuncture regulates the differentiation of microglia through PD-1/PD-L1 reducing secondary brain injury in acute phase intracerebral hemorrhage rats.

INTRODUCTION: This study aimed to investigate the effect of electro-nape-acupuncture (ENA) on the differentiation of microglia and the secondary brain injury in rats with acute-phase intracerebral hemorrhage (ICH) through the programmed cell death protein-1/ligand-1 (PD-1/PD-L1) pathway. METHODS: A total of 27 male Sprague-Dawley rats were randomly divided into three groups: sham group, ICH group, and ENA group. The autologous blood infusion intracerebral hemorrhage model was used to study the effects of ENA by administering electroacupuncture at GB20 (Fengchi) and Jiaji (EX-B2) acupoints on 24 h after the modeling, once per day for 3 days. The neurological function damage, hematoma lesion, and inflammatory cell infiltration were measured by the beam walking test and hematoxylin-eosin staining. The expression of PD-1, PD-L1, CD86, CD206, and related cytokines around the hematoma was measured by western blot, quantitative reverse transcription polymerase chain reaction, and immunofluorescence. RESULTS: The ICH group had significant neurological deficits (p < .001), hematoma lesions, and inflammatory cell infiltration. The levels of CD86 protein, inflammatory factors tumor necrosis factors (TNF)-α, interleukin (IL)-1ß, and IL-6 were increased (p < .001), while CD206 protein was reduced (p < .01), and the number of CD86+ /CD11b+ cells was also increased (p < .001) compared to the sham group. However, after ENA intervention, there was a significant reduction in neurological function damage (p < .05), infiltration of inflammatory cells, and the expression levels of CD86+ /CD11b+ cells (p < .05), resulting in the increased expression of PD-1 protein and differentiation of M2 phenotype significantly (p < .001). CONCLUSION: The study concludes that ENA could reduce neurological function damage, inhibit the expression of pro-inflammatory cytokines, and improve the infiltration of inflammatory cells to improve secondary brain injury in acute-phase intracerebral hemorrhage rats. These effects could be related to the increased expression of PD-1 around the lesion, promoting the differentiation of microglia from M1 to M2 phenotype.

Endovascular Management of Hematomas in Pediatric Transplant Patients.

OBJECTIVES: Transcatheter arterial embolization is used to control active hemorrhage at different anatomic locations. Because hematomas can suddenly deteriorate and become life threatening for transplant patients, they require prompt diagnosis and intervention rather than conservative management. Here, we evaluated computed tomography in treatment planning and transcatheter embolization effectiveness for hematoma management in pediatric liver transplant patients. MATERIALS AND METHODS: Between June 2012 and December 2021, 10 pediatric liver transplant patients were referred to our interventional radiology unit. Computed tomography and angiograms were reviewed for hematoma location and presence of extravasation. We analyzed correlations between computed tomography and angiography findings and technical and clinical success of the endovascular interventions. RESULTS: Active leak of contrast material during arterial phase was detected on 9/10 CT scans. Although there was no active bleeding on CT in 1 patient, active arterial bleeding was detected on angiography. On the contrary, in 2 patients, although active bleeding was observed on computed tomography, it was not detected on angiography. Source of bleeding was superior mesenteric artery branches in 4, hepatic artery branch in 2, superior epigastric artery in 1, and phrenic artery in 1 patient. Six of 8 patients with active bleeding were treated with endovascular procedures. The remaining 2 patients received surgery: 1 had bleeding from liver cut surface originating from a hepatic artery branch and received open surgery because the bleeding branch was too thin for catheterization, and 1 was hemodynamically unstable and selective catheterization of the internal thoracic artery would take time. Two patients received embolization procedures with N-butyl 2-cyanoacrylate (glue) diluted with iodized oil, and 1 patient had coil and glue with iodized oil. Embolization with coils was performed in 3 patients. Rate of success with transcatheter arterial embolization was 75%. No complications related to patient comorbidities or embolization procedures were shown. No deaths occurred due to progression of the hematoma. CONCLUSIONS: Transcatheter arterial embolization is effective and safe for treatment of pediatric liver transplant patients with hematomas. Computed tomography has value in identifying the bleeding source and its anatomic relationships and may enhance our intervention abilities to become quicker, more effective, and more secured.

Management of haematoma after thyroid surgery: systematic review and multidisciplinary consensus guidelines from the Difficult Airway Society, the British Association of Endocrine and Thyroid Surgeons and the British Association of Otorhinolaryngology, Head and Neck Surgery.

Haematoma after thyroid surgery can lead to airway obstruction and death. We therefore developed guidelines to improve the safety of peri-operative care of patients undergoing thyroid surgery. We conducted a systematic review to inform recommendations, with expert consensus used in the absence of high-quality evidence, and a Delphi study was used to ratify recommendations. We highlight the importance of multidisciplinary team management and make recommendations in key areas including: monitoring; recognition; post-thyroid surgery emergency box; management of suspected haematoma following thyroid surgery; cognitive aids; post-haematoma evacuation care; day-case thyroid surgery; training; consent and pre-operative communication; postoperative communication; and institutional policies. The guidelines support a multidisciplinary approach to the management of suspected haematoma following thyroid surgery through oxygenation and evaluation; haematoma evacuation; and tracheal intubation. They have been produced with materials to support implementation. While these guidelines are specific to thyroid surgery, the principles may apply to other forms of neck surgery. These guidelines and recommendations provided are the first in this area and it is hoped they will support multidisciplinary team working, improving care and outcomes for patients having thyroid surgery.

Esophageal Hematoma Associated with the Bolus Ingestion of Hot Coffee.

A 59-year-old woman presented with pharyngeal discomfort and dysphagia starting the previous day. Esophagogastroduodenoscopy revealed a longitudinal reddish area and hematoma mainly on the left wall of the esophagus. On the previous day, she had felt a piece of meat sticking in her throat while eating; she therefore rapidly gulped down some hot coffee to hasten the passage of the meat. Based on the history, we diagnosed her endoscopic findings as esophageal hematoma and thermal injury associated with hot coffee. We herein describe a case of an acute esophageal hematoma and thermal injury and the clinical course following endoscopy.

[Effect of manual acupuncture of "Shuigou" (GV26)"Neiguan" (PC6) on neurological function and expression of apoptosis-related factors in brain tissues surrounding hematoma in intracerebral hemorrhage rats].

OBJECTIVE: To observe the effect of manual acupuncture stimulation of "Shuigou" (GV26) and "Neiguan" (PC6) on neurological function and expression of Caspase-3 and Caspase-9 in brain tissues around the intracerebral hematoma in rats with acute intracerebral hemorrhage (ICH), so as to explore its possible mechanisms underlying improvement of ICH. METHODS: Ninety-six male SD rats were randomly divided into 4 groups: control, model, acupoint and non-acupoint (24 rats in each group). The ICH model was established by injection of the rat's autologous blood into the caudate nucleus. According to the time-points of 6, 24, 48 and 72 h after ICH, each of the 4 groups was further divided into 4 subgroups. For rats of the acupoint group, the PC6 on both sides was manually stimulated by manipulating the needle with lifting-thrusting-twisting reducing techniques, while the GV26 was stimulated with strong "sparrow-pecking" method for 10 times, then, left the needles in the acupoints for 30 min. For rats of the non-acupoint group, two non-acupoints: mid-spot below the bilateral axilla and the spot 3 mm above the left side of the coccyx tip were stimulated with the same methods to PC6 and GV26, respectively. For rats of the 6 h and 24 h subgroups, the intervention was given once after waking up from modeling, and for those of the 48 and 72 h subgroups, the intervention was conducted once a day for 2 or 3 times, respectively. The neurological severity score (NSS) was used to evaluate the degree of neurological function. The immunoactivity (expression) of Caspase-3 and Caspase-9 proteins of the hematoma focus of the brain was detected by immunohistochemistry. RESULTS: Following modeling, the NSS and the expression levels of Caspase-3 and Caspase-9 proteins in the brain tissues surrounding the hematoma at each time-points (6, 24, 48 and 72h) after modeling were significantly increased in the model group relevant to the control group (P<0.01, P<0.05). Compared with the model group, the NSS at 72h and the expression levels of Caspase-3 and Caspase-9 proteins at 6, 24, 48 and 72h were significantly down-regulated in the acupoint group (P<0.05) rather than in the non-acupoint group (P>0.05). CONCLUSION: Acupuncture of GV26 and PC6 can improve the neurological function in rats with ICH, which may be related to its function in reducing the expression of Caspase-3 and Caspase-9 proteins (apoptosis-related proteins) in the brain.

Early needle aspiration of large infant cephalohematoma: a safe procedure to avoid esthetic complications.

Cephalohematoma is a common pathology in newborns. Observation is the primary treatment for most patients with small uncomplicated cephalohematoma. Conversely, a large cephalohematoma can lead to calcification with unesthetic local deformation or deformational plagiocephaly. The objective of the study was to evaluate the iatrogenic risk associated with early puncture under local anesthesia and oral sucrose. This is a retrospective study of 67 consecutive newborns followed at Montpellier University Hospital, France, between 2010 and 2017. Large cephalohematoma was defined on the basis of the bump projection. Due to the uncertainty of the spontaneous resorption and the risk of calcification after 4 weeks which render the needle aspiration ineffective, puncture was performed between 2 and 4 weeks of life after coagulation evaluation and ultrasound of the skull and scalp. Puncture was performed in 43 boys (64%) and 24 (36%) girls between day 15 and day 30 after birth. The cephalohematoma maximal projection measured by ultrasound ranged from 9 to 13 mm (Q1,Q4) with a median value of 12 mm. No puncture-related complication was recorded during the intervention and at the 1-month follow-up visit.Conclusion: In newborns with large and persistent unesthetic cephalohematoma, puncture under local anesthesia with oral sucrose can be safely proposed between day 15 and day 30 after birth.What is Known:• Infant cephalohematoma is a frequent pathology of newborns, consisting of a traumatic subperiosteal hematoma of the skull. Most cephalohematomas are small and require no treatment because they spontaneously disappear within the first month.• Large and non-resorptive cephalohematomas may have significant esthetic and functional consequences.What is New:• Early puncture under local anesthesia is a safe, effective, and rapid procedure, decreasing the risk of persistent skull deformities.• Puncture can be proposed for newborns with a large (high projection and/or high angle connection) persistent anesthetic cephalohematoma, between day 15 and day 30, before spontaneous calcification.

[Early acupuncture for traumatic intracerebral hematoma: a randomized controlled trial].

OBJECTIVE: To observe the effect of early acupuncture intervention on brain edema in patients with traumatic intracerebral hematoma and explore its mechanism on the basis of conventional western medicine. METHODS: With stratified block randomization, sixty-four patients with glasgow coma scale (GCS) of 6 to 12 were divided into an acupuncture combined with medicine group (a combination group) and a western medication group, 32 cases in each one. In the western medication group, dehydration to reduce intracranial pressure and nutritional nerves were given as the basic treatment. In the combination group, on the basis of the treatment as the western medication group, acupuncture was applied at Xuehai (SP 10), Taixi (KI 3), Fenglong (ST 40), Yinlingquan (SP 9), Zusanli (ST 36), etc. The treatment was given once every day, for 6 times as one course; there was an interval of 1 day between two courses; a total of 4 courses were required. GCS score and recovery time were recored before treatment and on the 7 th, 14 th and 28 th days. 90 days follow-up after treatment, the GOS was observed, and the mortality and effective survival rate were calculated. The Barthel index (BI) score was evaluated before treatment and on the 14th, 21st, 28th days and 90 days follow-up after treatment. Before treatment and 3rd, 7th, 14th, 21st, 28th days, cranial CT or MR scan was performed to calculate the brain edema index (BEI); Plasma interleukin-6 (6IL-6), neuropeptide Y (NPY) and nitric oxide (NO) were measured before treatment and on the 3rd, 7th and 14th days after treatment. RESULTS: (1) The GCS scores increased gradually in the two groups during treatment, and there was significant difference between the 28th days and before treatment (both P<0.05). There were no significant difference between the two groups about GCS score and average recovery time on the 28th days treatment (all P>0.05). (2) The mortality rate of the combination group was 6.3% (2/32) on 90 days follow-up, 9.4% (3/32) in the western medication group (P>0.05). The effective survival rate was 81.3% (26/32) in the combination group, which was higher than 59.4% (19/32) in the western medication group (P<0.05). (3) The BI score was significantly higher than that before treatment on the 28th days and 90 days follow-up in the two groups (all P<0.05), and the result in the combination group was superior to that in the western medication group (both P <0.05). (4) The BEI decreased on the 14th, 21st and 28th days in the two groups (all P<0.05), and on the 14th day, the BEI decreased more significantly in the combination group than that in the western medication group (P<0.05). (5) The levels of IL-6, NPY and NO decreased on the 7th and 14th days in the two groups (all P<0.05), and decreased more significantly in the combination group than that in the western medication group on the 7th day (P<0.05). CONCLUSION: On the basis of conventional western medicine, early acupuncture can reduce cerebral edema and improve the prognosis of patients, and acupuncture combined with medicine are superior to western medicine alone. Acupuncture mechanism may be related to reducing the expression of inflammatory response.

Natural history of spontaneous isolated celiac artery dissection after conservative treatment.

OBJECTIVE: Optimal treatment of spontaneous isolated celiac artery dissection (SICAD) is not well established because the natural history of this rare disease is poorly understood. We analyzed the natural history of patients who underwent conservative treatment. METHODS: The study included 28 patients with SICAD from December 2008 to January 2017. Our institutional policy of first-line treatment for SICAD patients was conservative, and invasive procedures were reserved for unstable complications such as severe persistent pain, significant organ malperfusion, rapid aneurysmal change, and rupture or concealed rupture. Demographics, clinical features, morphologic characteristics on computed tomography, treatment modalities, and follow-up results of these patients were retrospectively reviewed. RESULTS: Mean age was 52 years, and 89% of patients were male; 86% presented with pain, mostly abdominal, and 14% of cases were detected incidentally on abdominal imaging. None of these patients had unstable complications on admission, and all underwent initial conservative treatment. During the follow-up period (22 ± 20 months), aneurysmal change and propagation of thrombosis were noted in one patient and two patients, respectively, all of whom were managed conservatively without adverse clinical events. No difference in clinical and morphologic outcomes was noted between patients who were treated with antihypertensive therapy and those who were not. Patients with intramural hematoma on initial images showed dynamic vascular remodeling (partial to complete resorption) during the follow-up period compared with patients who had dominant intimal flap on initial images. CONCLUSIONS: The clinical course of patients with SICAD was benign. Even progressive vascular changes during follow-up did not require invasive treatment. Antihypertensive therapy might not modify the clinical course. The short-term results of conservative management are encouraging, but further evaluation with long-term follow-up in a large population is needed.

Retroperitoneal Hemorrhage After Sacral Neurostimulator Placement for Urgency Urinary Incontinence.

Sacral neuromodulation (SNM) is an effective therapy for patients who experience urinary incontinence, idiopathic urinary retention, and fecal incontinence. Although typically a low-risk procedure, rarely, it can be associated with significant hemorrhage. A 61-year-old woman on chronic anticoagulation underwent uncomplicated implantation of SNM for refractory urgency urinary incontinence. Anticoagulation was held on the day of surgery and resumed on postoperative day 1. On postoperative day 2, the patient developed an extensive retroperitoneal hemorrhage. This was successfully treated by angioembolization of the left lateral sacral artery with the InterStim device left in situ. At 6-month follow-up, the device was functioning properly, and the patient's urinary symptoms were well controlled. Retroperitoneal hemorrhage is a rare complication after SNM placement. Conservative management with angioembolization should be considered as a first-line approach.

A Case of Ruptured Aneurysm of the Proper Esophageal Artery with Symptomatic Mediastinal Hematoma.

Mediastinal aneurysms are rare but potentially life-threatening. Among these, bronchial artery aneurysms are most frequently reported, whereas up to now aneurysms of the proper esophageal artery had never been reported. A 69-year-old woman was referred to our hospital for treatment of a massive mediastinal hematoma. Enhanced computed tomography and selective proper esophageal arteriography revealed a 5-mm aneurysm in the proper esophageal artery that arises from the thoracic aorta at the Th8 level and has an anastomotic branch with the bronchial artery peripherally. Transcatheter arterial embolization was successfully performed using a mixture of N-butyl cyanoacrylate and lipiodol (1:3 ratio, 0.3 ml). Post-embolization angiography showed no filling into the aneurysm. The patient recovered with no complications and was discharged on the 25th post-procedure day.

[Effect of Scalp Penetration Acupuncture on the Expression of NGF in Brain Tissue around Hematoma of Intracerebral Hemorrhage Rats].

Objective To observe the effects of scalp penetration acupuncture on the expression of nerve growth factor (NGF) in brain tissue around hematoma of intracerebral hemorrhage rats. Methods To- tally 120 healthy male Wistar rats were divided into the sham-operation group, the model group, the acupunc- ture group by random digit table, 40 in each group. Rats in each group were further randomly divided into 4 time points, i.e., 6 h, 24 h, day 3, day 7. The intracerebral hemorrhage rat model was prepared by modified autologous arterial blood method, intervened by electroacupuncture (EA) at Baihui (DU20) through Taiyang (EX- HN5). Neuroethological assessment was conducted by Longa score. The expression of NGF positive cells in brain tissue around hematoma was detected using immunohistochemical method. The amount of NGF mRNA expression was measured by q-PCR. Results Compared with the sham-operation group, neurobehavioral scores increased, NGF positive cells increased, NGF mRNA expression increased in the model group at each time point, with statistical difference shown (P <0.05). Compared with the model group, 6 h neurobehavioral scores,NGF positive cells, mRNA expression of NGF did not change significantly in the acupuncture group, with no statistical difference shown (P > 0. 05). Neuroethological scores decreased, NGF positive cells increased, mRNA expression of NGF was up-regulated in the acupuncture group at 24 h, day 3 and 7, respec- tively, with statistical difference shown (P <0. 05). Conclusion scalp penetration acupuncture could up-regulate gene and protein expressions of NGF, and promote recovery of nerve function, showing favorable neuro-protective effects.

[Impacts of acupuncture on blood pressure and hematoma in patients of cerebral hemorrhage at the early stage].

OBJECTIVE: To explore the therapeutic effect of acupuncture for hypertensive cerebral hemorrhage at the early stage. METHODS: Fifty-four cases of small-amount cerebral hemorrhage were randomized into an acupuncture group and a conventional treatment group, 27 cases in each one. In the conventional treatment group, special care, oxygen therapy, nerve nutrition and symptomatic support were applied. In necessary, dehydrant and hypotensive drugs were prescribed for antihypertension, or surgery was given. In the acupuncture group, on the basis of the treatment as the control group, acupuncture was applied at Quchi (LI 11), Neiguan (PC 6), Zusanli (ST 36), Sanyinjiao (SP 6) and Taichong (LR 3). Acupuncture was given at the admission, 4 h, 6 h and 12 h after disease onset respectively. Blood pressure was monitored in the whole procedure. 6 h and 24 h after disease onset, the cranial CT was re-examined. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), hematoma volume and neurological deficit score were compared at different time points between the two groups. RESULTS: (1) Blood pressure: from the admission to 12 h after disease onset, SBP, DBP and MAP were increased apparently in the conventional treatment group and increased slightly in the acupuncture group. The differences in SBP [(164.3 +/- 21.6) mmHg vs (158.6 +/- 21.5) mmHg] and MAP [(113.4 +/- 4.9) mmHg vs (106.7 +/- 6.1) mmHg] were significant between the two groups (both P < 0.05). From 12 h to 24 h after disease onset, compared with the conventional treatment group, SBP and MAP were decreased apparently in the acupuncture group [(147.3 +/- 21.6) mmHg vs (158.4 +/- 23.5) mmHg, (97.2 +/- 5.3) mmHg vs (106.6 +/- 5.1) mmHg, both P < 0.05)]. (2) Hematoma volume: from the admission to 6 h after disease onset, the volume was increased by (4.15 +/- 0.73) mL in the convertional treatment group and (2.67 +/- 0.33) mL in the acupuncture group, indicating the significant difference in comparison (P < 0.05). From the admission to 24 h after disease onset, it was increased by (5.57 +/- 1.26) mL in the convertional treatment group and (3.14 +/- 1.18) mL in the acupuncture group, indicating the significant difference in comparison (P < 0.05). (3) Neurological deficit score: the score was increasing gradually in first 3 days after disease onset in the two groups. The score (38.39 +/- 6.84) in the acupuncture group on the first day was different significantly as compared with that (42.37 +/- 7.46) in the conventional treatment group (P < 0.05). On the 10th days, the score (24.68 +/- 5.42) in the acupuncture group was different significantly from that (29.74 +/- 7.36) in the convertional treatment group (P < 0.05). CONCLUSION: There is no peak of blood pressure rising, and the continuous hemorrhagic volume is less in 24 h and neurological deficit score is improved in the acupuncture group. Acupuncture brings the positive significance in the treatment of cerebral hemorrhage at the early stage.

Medicinal leech therapy in pain syndromes: a narrative review.

Medicinal leech therapy is used in a variety of conditions; most of which have pain as a major symptom. Its mode of action relies on the injection of leech saliva into patients' tissues during the process of blood withdrawal. Leech saliva contains active ingredients with anti-inflammatory, thrombolytic, anti-coagulant and blood- and lymph-circulation enhancing properties. A specific analgesic substance within the leech saliva is yet to be identified. Pain relief from leech therapy is rapid, effective and long-lasting in many conditions. This review compiles studies and case reports that provide clinical evidence for leech therapy's analgesic effects.
