Methods: For June 2005 to June 2009 inour hospital a total of organophosphorus pesticide poisoning 281 cases were divided into A group and B group, All patients were using atropine therapy, 132 cases of sequential therapy in patients with atropine is divided into A group, 149 cases of routine use of intravenous injection and intramuscular injection of atropine group patients were divided into B group, From the following aspects were analyzed and summarized, They are the maintenance of the effect of atropinization, the average time for the beginning of withdrawal, the total hospitalization costs, the total average time for hospitalization and nurses labor intensity. According to the organic phosphorus pesticide on the efficacy of cholinesterase agents are divided into efficient and inefficient groups groups, From the types of poisons, toxic ways, poisoning performance and Complications for stratified, They were divided into 4 groups, severe organophosphorus pesticide poisoning and cholinesterase reactivator can be highly effective group, severe organophosphorus pesticide poisoning and cholinesterase reactivator Lowefficacy group, mild organophosphorus pesticide poisoning and cholinesterase reactivator can be highly effective group, mild organophosphorus pesticide poisoning and cholinesterase reactivator Lowefficacy group, Correlation analysis Antijumping and the incidence of intermediate syndrome and atropinization time.Results:Maintain the efficacy of atropine of A group and B were significantly different between groups, Plt;0.01, the average time began to withdraw drugs, the total average time for hospitalization, total hospital charges, nursing labor intensity of A group and B are differences between the two groups, P＜0.05. Rebound occurs and the incidence of intermediate syndrome, to atropinization time high between the two groups showed no difference between the two groups showed no differences between inefficient and efficient group and inefficient group were significantly different, Plt;0.01, mainly related to poisoning by drug type and severity of illness, followed with atropine therapy. Conclusion:Atropine sequential therapy is superior to organophosphorus pesticide poisoning by conventional atropine treatmen.
ObjectiveTo investigate the effectiveness of debridement-vacuum sealing drainage (VSD)-modified external fixation antibiotic-impregnated cement semi-open technique in treatment of chronic ulcer wounds. MethodsClinical data of 43 patients with chronic ulcer wounds who met the selection criteria and admitted between January 2019 and June 2023 were retrospectively analyzed. Among them, 23 cases were treated with debridement-VSD-modified external fixation antibiotic-impregnated cement semi-open technique (improved group), and 20 cases were treated with debridement-VSD-traditional antibiotic-impregnated cement technique (control group). There was no significant difference in gender, age, constituent ratio of patients with type 2 diabetes mellitus, constituent ratio of patients with smoking history, body mass index, wound site, and other baseline data between the two groups (P>0.05). The healing quality and healing time, the positive rate of bacterial culture after bone cement coating, the loosening rate of bone cement, the number of operations, the number of hospitalizations, the length of hospitalization, and the cost of hospitalization were recorded and compared between the two groups. Results Compared with the control group, the positive rate of bacterial culture after bone cement coating and the loosening rate of bone cement in the improved group was significantly lower, as well as the number of operations, the number of hospitalizations, the length of hospitalization, and hospitalization cost significantly reduced (P<0.05). Wound repair was completed in both groups without amputation. The wound healing quality of the improved group was better than that of the control group and the wound healing time was shorter, the differences were significant (P<0.05). All patients were followed up 1-5 years (mean 3.4 years), and no ulcers recurred during follow-up. ConclusionDebridement-VSD-modified external fixation antibiotic-impregnated cement semi-open technique in the treatment of chronic ulcer wounds can effectively reduce the loosening rate of bone cement, facilitate the induced membrane formation and wound healing, and significantly reduce the number of operations and shorten the length of hospital stay.
Objective To review the clinical research progress of craniofacial duplication, improve clinicians’ recognition of this disease, and provide theoretical basis and practical references for its precise diagnosis and individualized treatment. Methods Recent domestic and international literature on craniofacial duplication as well as the diagnosis and treatment experiences of clinical cases in our team were reviewed. A comprehensive elaboration was conducted from embryonic development, etiological hypotheses, clinical classification, imaging manifestations, multidisciplinary diagnosis and treatment strategies, and prognostic follow-up. Special focus was placed on summarizing clinical features of jaw duplication, characteristics of occlusal disorder, and sequential orthodontic-orthognathic combined therapy. Results Craniofacial duplication is an extremely rare congenital craniofacial developmental malformation with highly heterogeneous phenotypes, involving multiple structures including lips, oral cavity, maxilla, and mandible. It is often complicated by cleft lip and palate, cervical vertebral fusion, hypertelorism, muscular dysfunction and other deformities, severely impairing patients’ mastication, phonation, deglutition, and facial aesthetics. Due to its extremely low incidence, scattered reported cases, and unclear pathogenesis, unified diagnostic criteria and therapeutic specifications have not been established worldwide. Developmental disorders of pharyngeal arches and cranial neural crest cells at embryonic weeks 4-8 are the core pathogenic trigger. The five etiological hypotheses have limited evidence levels, and no single theory can explain all clinical subtypes. The PAX7 gene variant identified by our team only serves as a genetic clue without functional verification to confirm its pathogenicity. The modified Hamberis 3-type classification and Sun 4-type mandibular duplication classification can clearly define the lesion scope, with matched surgical procedures, orthodontic regimens and recurrence risks for each subtype. Cone-beam computed tomography (CBCT) combined with three-dimensional reconstruction acts as the gold standard for diagnosis, and multidisciplinary sequential therapy can ameliorate facial appearance and oral function. Nevertheless, long-term follow-up data are scarce, and clinical management mainly relies on individualized experiences of clinicians. Conclusion Craniofacial duplication features complicated pathogenesis characterized by duplicated jaws, lips, and dental arches, with dysregulated development of embryonic pharyngeal arches and cranial neural crest cells as the core inducement. CBCT three-dimensional reconstruction enables accurate diagnosis, and multidisciplinary sequential therapy represents the optimal intervention strategy. Shortcomings including scarce clinical cases, unidentified pathogenic genes, absent standardized therapeutic protocols and insufficient long-term follow-up evidence remain prominent. Future research directions include constructing a multi-center case registry, conducting functional research on pathogenic genes, popularizing digital diagnosis and treatment techniques, and formulating standardized diagnostic and therapeutic guidelines. For pediatric patients with suspected malformations, CBCT examination should be performed as early as possible, and the principle of early diagnosis, early planning and early intervention shall be followed to restore oral function and optimize maxillofacial appearance.
