Objective:To analyze the clinical features of adult deficiency of adenosine deaminase 2 (DADA2) with neurological impairment.Methods:The clinical data of an adult DADA2 patient with concurrent neurological damage who visited the Department of Neurology, Mindong Hospital Affiliated to Fujian Medical University on September 18, 2023 were retrospectively analyzed. The clinical studies or case reports related to adult DADA2 with nervous system involvement from Pubmed, CNKI, and Wanfang databases were retrieved, and the clinical characteristics of adult DADA2 with neurological damage were summarized. The clinical data of children with nervous system involvement in the same study cohorts were also collected, and the clinical features of DADA2 between adults and children were compared.Results:The patient was a 30-year-old male, mainly presenting with manifestations of livedo reticularis, stroke and spastic paraplegia. Genetic testing showed a compound heterozygous mutation in the adenosine deaminase 2 ( ADA2) gene, and brain MRI showed lacunar infarcts in the right basal ganglia and thalamus, hypertrophic inferior olivary degeneration. The literature review found that a total of 22 adult DADA2 patients with neurological damage have been reported, with a onset age of 25 (19, 29) years. Stroke was the most common feature of neurological involvement in patients with this disease (17/22, 77.3%), followed by cranial nerve damage (7/22, 31.8%) and limb nerve damage (8/22, 36.4%). After the treatment with tumor necrosis factor (TNF) inhibitors, the condition of 17/20 patients remained stable or improved. Compared with pediatric DADA2 patients with concurrent neurological damage, the incidence of fever [12/22(54.5%) vs 48/59(81.4%)], arthritis [6/22(27.3%) vs 34/59(57.6%)], and hematological abnormalities [4/22(18.2%) vs 28/60(46.7%)] in adult DADA2 patients was significantly reduced, and the difference was statistically significant (χ 2=5.998, 5.907, 5.489, respectively, all P<0.05). Conclusions:Adult DADA2 with concurrent neurological damage generally onset in early adulthood, mainly manifested as stroke, and may also be accompanied by peripheral nerve damage. Adult patients have fewer systemic symptoms than children, and timely treatment with TNF inhibitors can lead to better outcomes.

Objective:To observe any effect of percutaneous tibial nerve stimulation (PTNS) combined with electro-acupuncture on detrusor overactivity after a spinal cord injury.Methods:Forty spinal cord injury survivors with neurogenic detrusor overactivity were randomly assigned to a control group or an observation group, each of 20. Both groups received routine bladder training and electro-acupuncture modulating 3 sacral spinal nerves. The observation group also received 20 minutes of bilateral PTNS five times a week for 8 weeks. The frequency was 10Hz with a pulse width of 200μs. Before and after the treatment, both groups′ urination frequency, incontinence and average daily urine volume were assessed using a urodynamics analyzer, bladder diaries and an incontinence quality of life questionnaire (I-QOL).Results:After treatment, the average involuntary detrusor contraction volume (IDCV), maximum detrusor pressure at filling time (P det·max), bladder compliance (BC), residual volume and the TL value of the electromyogram of the urethral sphincter (LgTLR) had all improved significantly in both groups. The 1st IDCV, BC and LgTLR of the observation group were then significantly better than in the control group, on average, with the average P det·max and residual volume significantly lower than in the control group. The average daily single urine output and I-QOL score of both groups had increased significantly, while the average daily urination frequency and frequency of urinary incontinence had decreased significantly. Both were again significantly better in the observation group. Conclusion:Combining percutaneous electrical stimulation of the tibial nerves with electro-acupuncture can effectively inhibit detrusor overactivity after a spinal cord injury, reducing urinary incontinence.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.

Objective:To study the clinical features of transthyretin amyloid polyneuropathy (ATTR-PN) caused by Ser77Tyr mutation.Methods:The clinical data of a patient with ATTR-PN caused by Ser77Tyr mutation, admitted to our hospital from Department of Neurology, Mindong Hospital Affiliated to Fujian Medical University, were retrospectively analyzed. Literature on patients with ATTR-PN caused by Ser77Tyr mutation in Pubmed, Web of Science, CNKI and Wanfang databases and those with ATTR-PN caused by Val30Met mutation in Pubmed and Web of Science were searched and screened, and clinical characteristics of these patients were extracted. The differences of clinical characteristics among patients with ATTR-PN caused by Ser77Tyr or Val30Met mutations were compared.Results:(1) Transthyroxin ( TTR) gene Sanger sequencing results showed Ser77Tyr heterozygous pathogenic mutation; Congo red staining of biopsy sample in the patient 2.5 years after onset showed amyloid deposition. (2) Seventy-eight patients with ATTR-PN caused by Ser77Tyr mutation were summarized, they mostly had onset at 50-60 years old; male patients had higher incidence (74.4%); most patients (78.0%) had positive family history; most patients had sensory symptoms as initial symptom (72.0%), which gradually progressed to extensive peripheral nerve involvement and combined with widespread heart damage (96.4%) over several years; electrophysiological examination mainly showed axonal damage and carpal tunnel syndrome; the tissue biopsy had high positive rate(84.8%). (3) There were 192 and 96 patients with ATTR-PN caused by early-onset and late-onset Val30Met mutations, respectively; compared with patients with ATTR-PN caused by early-onset Val30Met mutation, patients with ATTR-PN caused by Ser77Tyr mutation had significantly higher incidence of deep sensory disturbance (28.6% vs. 58.5%, P<0.05). Compared with patients with ATTR-PN caused by late-onset Val30Met mutation, patients with ATTR-PN caused by Ser77Tyr mutation had increased incidence of mild sensory disturbance (56.3% vs. 75.0%) and decreased incidence of limb weakness (65.6% vs. 48.3%), with significant differences ( P<0.05). ATTR-PN patients caused by Ser77Tyr mutation had significantly higher incidence of carpal tunnel syndrome than ATTR-PN patients caused by early-onset and late-onset Val30Met mutations (75.4% vs. 10.8% and 25.0%) and significantly higher incidence of cardiac damage than ATTR-PN patients caused by early-onset Val30Met mutation (96.4% vs. 80.5%, P<0.05). Conclusion:Ser77Tyr mutation has some distinctive clinical features: relatively balanced damage of large and small fibers, prominent carpal tunnel syndrome, and obvious heart disease; early identification of these features and administration of tissue biopsy and gene detection are helpful for early diagnosis.

Objective:To evaluate the safety and efficacy of Delorme procedure for adults with full-thickness rectal prolapse.Methods:Clinical data of 17 adult patients suffering from full-thickness rectal prolapse undergoing Delorme procedure from June 2014 to May 2018 in Hangzhou Third Hospital were retrospectively analyzed. Patient characteristics, operative data, postoperative complications, recurrence of rectal prolapse, continence state and constipation state were evaluated.Results:Eleven patients were female, 6 patients were male with a mean age of (68 ± 9) years. Operations were successfully performed in these 17 cases. The operation time was (88 ± 16) minutes. The estimated blood loss during operation was (23 ± 9) ml. The postoperative time of hospital stay was (8 ± 1) d. Two complications in two patients were observed. There was no treatment related death. One recurrent case was observed during (16 ± 2) months follow-up. The preoperative and postoperative mean constipation score of five patients with fecal constipation were (23 ± 2) and (11 ± 3) respectively ( t = 9.51, P<0.01). The mean fecal incontinence score of six patients with fecal incontinence, before and after Delorme procedure, were (14 ± 2) and (6 ± 2) respectively ( t = 9.09, P<0.01). Conclusions:The Delorme procedure for adults with full-thickness rectal prolapse is a safe and effective surgery with less complications and low recurrence rate. The Delorme procedure may be one of the preferred option of perineal approach for adults with full-thickness rectal prolapse, but the long-term outcome of Delormer procedure and its effect on postoperative anal function need to be further studied.

Blast injury of the chest injury is the most common wound in modern war trauma and terrorist attacks, and is also the most fatal type of whole body explosion injury. Most patients with severe blast injury of the chest die in the early stage before hospitalization or during transportation, so first aid is critically important. At present, there exist widespread problems such as non-standard treatment and large difference in curative effect, while there lacks clinical treatment standards for blast injury of the chest. According to the principles of scientificity, practicality and advancement, the Trauma Society of Chinese Medical Association has formulated the guidance of classification, pre-hospital first aid, in-hospital treatment and major injury management strategies for blast injury of the chest, aiming to provide reference for clinical diagnosis and treatment.

Objective:To compare the efficacy of standardized incision and conventional incision for reduction and internal fixation of multiple rib fracture.Methods:A retrospective cohort study was conducted to analyze the clinical data of 192 patients with multiple rib fracture treated in 909th Hospital of Joint Logistics Support Force (Affiliated Dongnan Hospital of Xianmen University Medical College) from January 2020 to January 2022. There were 101 males and 91 females; aged 32-94 years [(51.5±16.6)years]. The patients underwent open reduction and internal fixation with nickel-titanium shape memory alloy embracer via standard incision such as anterior axillary longitudinal incision (standard incision group, n=96) or conventional incision such as posterolateral incision (conventional incision group, n=96). The incision length, operation time, intraoperative blood loss, number of fixed fractures, indwelling time of closed thoracic drainage tube, postoperative thoracic drainage volume, postoperative spontaneous ambulation time and length of hospital stay were compared in the two groups. The visual analogue scale (VAS) was used to evaluate pain at 1 month after operation. Postoperative complications were recorded. Results:All patients were followed up for 1-16 months [4.0(3.0, 10.5)months]. The operation time, intraoperative blood loss, indwelling time of closed thoracic drainage tube, postoperative thoracic drainage volume, postoperative spontaneous ambulation time, length of hospital stay and VAS at postoperative 1 month in standard incision group [(12.1±1.6)cm, (51.4±13.0)minutes, (191.5±16.8)ml, (2.8±0.6)days, (568.9±109.0)ml, (4.1±0.7)days, (11.4±1.7)days, (2.5±0.7)points] were better than those in conventional incision group [(13.7±1.9)cm, (62.0±8.8)minutes, (248.9±65.4)ml, (4.8±1.1)days, (655.9±121.9)ml, (5.2±0.9)days, (15.3± 1.7)days, (3.5±0.7)points] ( P<0.05 or 0.01). There was no statistical difference in the number of fixed fractures between standard incision group and conventional incision group (5.1±0.8 vs. 5.4±0.9) ( P>0.05). In standard incision group, there were 3 patients with poor wound healing, 5 with pulmonary infection, 3 with atelectasis and 3 with small pleural effusion. In conventional incision group, there were 11 patients with poor wound healing, 9 with pulmonary infection, 7 with atelectasis and 7 with small pleural effusion. The incidence of postoperative complications was 14.6% (14/96) in standard incision group and 35.4% (34/96) in conventional incision group ( P<0.01). Conclusion:For multiple rib fracture, standard incision is superior to conventional incision reduction in shortening the incision length, operation time, indwelling time of drainage tube, postoperative spontaneous ambulation time and length of hospital stay, reducing the intraoperative blood loss and postoperative thoracic drainage volume, alleviating the pain and reducing the postoperative complications.
