OBJECTIVE: To summarize the progress of clinical diagnosis and treatment of diabetic Charcot neuroarthropathy (CNO) of foot and ankle to provide reference for clinical treatment. METHODS: The research literature on diabetic CNO of foot and ankle at home and abroad was widely reviewed, and the stages and classification criteria of CNO were summarized, and the treatment methods at different stages of the disease course were summarized. RESULTS: CNO is a rapidly destructive disease of bone and joint caused by peripheral neuropathy, which leads to the formation of local deformities and stress ulcers due to bone and joint destruction and protective sensory loss, which eventually leads to disability and even life-threatening. At present, the modified Eichenholtz stage is a commonly used staging criteria for CNO of foot and ankle, which is divided into 4 stages by clinical and imaging manifestations. The classification mainly adopts the modified Brodsky classification, which is divided into 6 types according to the anatomical structure. The treatment of diabetic CNO of foot and ankle needs to be considered in combination with disease stage, blood glucose, comorbidities, local soft tissue conditions, degree of bone and joint destruction, and whether ulcers and infections are present. Conservative treatment is mainly used in the active phase and surgery in the stable phase. CONCLUSION The formulation of individualized and stepped treatment regimens can help improve the effectiveness of diabetic CNO of foot and ankle. However, there is still a lack of definitive clinical evidence to guide the treatment of active and stable phases, and further research is needed.

OBJECTIVE: To investigate the clinical effect the treatment of arthroscopy-assisted calcaneal spur resection combined with plantar fascia release and calcaneal decompression in the treatment of the patients with intractable calcaneal pain. METHODS: The clinical data of 50 patients with intractable heel pain from January 2016 to January 2019 were retrospectively analyzed, including 20 males and 30 females;aged from 40 to 68 years old with an average of (50.12±7.35)years old, the medical history ranged from 1 to 4 years. All patients underwent arthroscopy-assisted calcaneal spur resection combined with plantar fascia release and calcaneal decompression, and were followed up, the duration ranged from 24 to 60 months with an average of(42.00±3.28) months. All patients had obvious heel pain before surgery, and X-ray examinations often showed the presence of calcaneal spurs. In addition to the routine foot examination, the changes in the height and angle of the arch of the foot were also measured pre and post-operatively by X-ray, for the evaluation of clinical effect. The VAS system was used to evaluate the degree of foot pain;the AOFAS scoring system was used to comprehensively evaluate the foot pain, voluntary movement, gait and stability. RESULTS: The VAS decreased from (8.75±1.24) before surgery to (5.15±2.35) at 3 months after surgery, (4.07±2.53) at 6 months after surgery, and (3.95±2.44) at the last fllow-up(P<0.05). The AOFAS score increased from (53.46±4.17) before surgery to(92.46±2.53) at 3 months after surgery, (96.33±2.46) at 6 months after surgery, and (97.05±2.37) at the last follow-up(P<0.05). The arch height was (41.54±1.15) mm before operation and (41.49±1.09) mm after the operation, the difference was not statistically significant(P>0.05). The internal arch angle of the foot arch was (121±6)° before operation and (122±7)° after operation. The difference was not statistically significant(P>0.05). CONCLUSION Arthroscopy-assisted calcaneal bone spurs resection combined with plantar fascia release and calcaneal decompression exhibited great clinical effect for treating intractable heel.

Diabetic ulcer(DU) is a chronic and refractory ulcer which often occurs in the foot or lower limbs. It is a diabetic complication with high morbidity and mortality. The pathogenesis of DU is complex, and the therapies(such as debridement, flap transplantation, and application of antibiotics) are also complex and have long cycles. DU patients suffer from great economic and psychological pressure while enduring pain. Therefore, it is particularly important to promote rapid wound healing, reduce disability and mortality, protect limb function, and improve the quality of life of DU patients. By reviewing the relevant literatures, we have found that autophagy can remove DU wound pathogens, reduce wound inflammation, and accelerate ulcer wound healing and tissue repair. The main autophagy-related factors microtubule-binding light chain protein 3(LC3), autophagy-specific gene Beclin-1, and ubiquitin-binding protein p62 mediate autophagy. The traditional Chinese medicine(TCM) treatment of DU mitigates clinical symptoms, accelerates ulcer wound healing, reduces ulcer recurrence, and delays further deterioration of DU. Furthermore, under the guidance of syndrome differentiation and treatment and the overall concept, TCM treatment harmonizes yin and yang, ameliorates TCM syndrome, and treats underlying diseases, thereby curing DU from the root. Therefore, this article reviews the role of autophagy and major related factors LC3, Beclin-1, and p62 in the healing of DU wounds and the intervention of TCM, aiming to provide reference for the clinical treatment of DU wounds and subsequent in-depth studies.

With three representative types of gynecological diseases (dysmenorrhea, pelvic inflammation, polycystic ovary syndrome) as examples, the application methods of meridian and acupoint diagnosis for gynecological diseases treated with acupuncture and moxibustion are discussed. During clinical diagnosis and treatment, it is recommended to examine the patient's leg segment along the three yin meridians of foot, aiming to explore the positive reactions of the meridians and acupoints (color, shape, skin temperature, sensory abnormalities, etc.). Acupuncture and moxibustion treatment at this positive reaction place can improve the clinical efficacy. Meridian and acupoint diagnosis could provide basis for meridian syndrome differentiation, thus guiding the selection of acupoint prescriptions; it is also helpful to clarify the deficiency, excess, cold and heat of the disease nature, thus guiding the selection of acupuncture and moxibustion methods. In addition, it is an auxiliary method to estimate the prognosis and outcome of the disease.

OBJECTIVE: To analyze radiological characteristics of Muller-Weiss disease, evaluate the clinical value of the imaging examination in diagnosis of Muller-Weiss disease. METHODS: The imaging data of 26 patients with Muller-Weiss disease were collected from September 2015 to August 2020, including 7 males and 19 females, aged 43 to 68 years old with an average of (52.7±4.6) years old. In the X-ray examination observed the shape and position of the navicular bone. The talar-first metatarsal angle(TFM) was measured on the weight-bearing anteroposterior radiograph. The arch angle and angle between mid-axis of talus and mid-axis of the first metatarsal(Meary angle) were measured on the weight-bearing lateral radiographs. The morphology, density, adjacent joint space and position of the navicular bone were evaluated by computed tomography(CT), and magnetic resonance imaging(MRI) was used to observe the shape, signal, cartilage and surrounding soft tissue changes of the navicular bone. RESULTS: Among 26 patients, 21 cases were unilateral and 5 cases were bilateral;X-ray examination showed that the lateral part of navicular bone of foot was compressed and flattened, showing"comma like"or"drop like", navicular moved to the medial side, partial fragmentation of bone, peripheral articular hyperplasia, uneven density and narrowing of relationship gap. According to Meary angle and deformity degree of the affected foot on the lateral X-ray of the load-bearing foot, Maceira staging was performed. There were 0 cases in stageⅠ, 2 cases in stage Ⅱ, 11 cases in stage Ⅲ, 9 cases in stage Ⅳand 4 cases in stage Ⅴ. CT examination showed bone fragmentation, medial displacement of navicular bone and formation of the talocalcaneal joint. MRI examination showed the irregular shape and uneven signal of navicular bone, narrowing of joint space, talocalcaneal joint surface hyperplasia and cartilage destruction, tarsal joint effusion and swelling of surrounding soft tissue. CONCLUSION Muller-Weiss disease has specific imaging manifestation, and an accurate diagnosis can be made based on the patient's age, gender, and clinincal history. Preoperative imaging examination can stage the disease, help clinicians to formulate better surgical plans, and postoperative imaging examination can better evaluate the surgical effect.

Background: Pyoderma gangrenosum is a rare ulcerative skin disease that can present as an ulcerative skin disease with the prominence of pain. The pathogenesis may be related to disruptions in the immune pathways. Targeted therapy is lacking and current treatment is largely empirical and consists of corticosteroids and cyclosporine first line. Early recognition can improve clinical outcomes. Case: This case is a 67-year-old male diabetic who was admitted for a progressive ulcerative lesion on the right leg. Arterial Doppler studies and CT angiogram of the right lower extremity were normal. Blood and deep wound cultures of the lesion showed Klebsiella pneumoniae and Pseudomonas aeruginosa. Multiple antibiotic regimens were given with no improvement of the ulcerating lesions of the leg. Pain on the lesion remained persistent. The tissue biopsy of the lesion taken during debridement revealed that it was a pyoderma gangrenosum with dystrophic sclerosis. Oral prednisone at 1 mg/kg was added to the regimen which improved pain but the lesion did not improve. The persistence of the pain and progression to sepsis during the hospital course prompted the decision to do an above-knee amputation of the right leg. He was discharged improved. Conclusion Pyoderma gangrenosum is a rare non-infectious cause of an ulcerative lesion in the lower extremity. Diabetes is a strong risk factor for this disease. The course is prolonged with the possibility of secondary infections. Upon histopathologic confirmation, an anti-inflammatory regimen could help improve outcomes.

OBJECTIVE: To compare clinical efficacy of scarf osteotomy and double metatarsal osteotomy(DMO) in treating moderate to severe hallux valgus. METHODS: Fifty patients (81 feet) with moderate to severe hallux valgus deformity were treated from January 2017 to December 2019, and were divided into Scarf osteotomy (SO) group or DMO group according to different osteotomy methods. There were 26 patients (44 feet) in SO group, including 1 male and 25 females, aged from 48 to 65 years old with an average of (55.5±4.67) years old;18 patients (30 feet) with moderate and 8 patients (14 feet) with severe. There were 24 patients(37 feet) in DMO group, including 1 male and 23 females, aged from 45 to 62 years old with an average of (52.1±6.8) years old;there were 14 patients (24 feet) with moderate and 10 patients (13 feet) with severe. Hallux valgus angle (HVA), intermetatarsal angle (IMA), distal metatarsal articular angle (DMAA) and relative length of the first metatarsal(RLFM) on weight-bearing anteroposterior radiographs before and after operation were compared. American Orthopaedic Foot and Ankle Society (AOFAS) hallux, metatarsal, and interphalangeal joint scores was used for evaluate clinical effects. Weight bearing time and complications were observed. RESULTS: Fivty patients were followed up. The follow-up time in SO group ranged from 12 to 36 months with an average of(20.50±6.22) months and from 16 to 28 months with an avaerge of(19.80±2.44) months in DMO group while there was no significant difference between two groups(P>0.05). All incision healed at stage I, and osteotomy healed at (20.31±3.17) months after operation. One patient occurred hallux adduction deformity, without transferred metatarsalgia;2 patients occurred metastatic metatarsalgia in DMO group. There were no significant difference in HVA, IMA, DMAA, and AOFAS scores between two groups(P>0.05) before and after operation. There was no significant difference in RLFM between two groups(P>0.05), while had significant difference in RLFM between two groups at final follow-up (P<0.05). Partial weight-bearing time and full weight-bearing time in SO group were significantly earlier than those in DMO group (P<0.05). CONCLUSION Both of Scarf osteotomy and the first metatarsal biplane osteotomy could effectively treat moderate to severe hallux valgus deformity, with similar imaging and clinical evaluation. However, the relative length of the first metatarsal bone in SO group was longer than that in DMO group after operation, and the time of weight bearing in Scarf osteotomy is earlier than that of double metatarsal osteotomy of the first metatarsal.

OBJECTIVE: To evaluate clinical efficacy of modified kidner procedure with tendoscopy in treating painful accessory navicular. METHODS: From February 2014 to April 2019, 19 patients with painful accessory navicular were admitted, including 13 males and 6 females with a mean age of 26 years old (ranged from 14 to 58 years old), all of which were unilateral symptoms. The courses of disease ranged from 6 to 60 months. All patients received excision of accessory navicular and reconstruction of posterior tibial tendon insertion on navicular with anchor, and the tendoscopy were used to examin the posterior tibial tendon. American Orthopedic Foot and Ankle Society(AOFAS) midfoot score and visual analogue scale(VAS) were used to evaluate efficacy before operation and at the latest follow-up. RESULTS: All the patientswere followed up, and the duration ranged from 12 to 73 months, with an average of (35.0±20.9) months. VAS score was 0.20±0.41 at the latest follow-up, showing significant difference when compared with preoperative score of 6.33±1.95( CONCLUSION The modified kidner procedure with tendoscopy is a good choice for the treatment of painful accessory navicular, which could obviously relieve foot pain, improve foot function, and has certain clinical efficacy.

Objectives: To determine the risk factors for recurrence and persistence of non-healing foot ulcers resulting in minor and major amputations. Methodology: This was an ambispective cohort analysis of persons with diabetic foot ulcers consulting at the diabetic foot clinic of East Avenue Medical Center. Data were analyzed through multiple logistic regression. Result: Two hundred sixteen patients with Type 2 Diabetes Mellitus and diabetic foot ulcers were included in the analysis; 50.9% were males and the mean age of the cohort was 55.8 ± 9.9 years. Outcomes of foot ulcers were: healed 44.5% (healed with no recurrence 30%, healed but with recurrence 14.5%) and not healed 55.5% (major amputation 11%, minor amputation, 21.5%, and persistently non-healing 23%). Multivariate logistic regression showed the following were independent risk factors for persistent non-healing ulcer: osteomyelitis (OR 66.5; CI 19.7, 217.8), smoking (OR 28.9; CI 6.8, 129.3, and peripheral arterial disease (PAD) (OR 56.8; CI 2.5, 877.2). Independent risk factors for ulcer recurrence were: plantar location of ulcer (OR 16.8; CI 6.8, 89.4), presence of more than one ulcer (OR 7.8; CI 3.6,31.6), and neuropathy (OR 11.2; CI 7.2, 19.9). For healed foot ulcers, mean healing time was 14 ± 3 weeks. Healing time was significantly reduced from 12 weeks to 4.5 weeks (p<0.001) if patients consulted earlier (within 4 weeks from sustaining an ulcer). Conclusion Only half (55%) of patients with diabetic foot ulcers consulting in a dedicated outpatient foot clinic had an adverse outcome of foot ulcers (major amputation 11%, minor amputation, 21.5%, and persistently non-healing ulcer 23%) while a small portion (14.5%) of patients had recurrent foot ulcers. Arterial obstruction, smoking, low hemoglobin, neuropathy, and osteomyelitis increase the likelihood of healing failure while the presence of multiple ulcers, plantar location of ulcers, and neuropathy increase the risk of ulcer recurrence.

Objective: We aimed to assess the features of notifiable infectious diseases found commonly in foreign nationals in China between 2004 and 2017 to improve public health policy and responses for infectious diseases. Methods: We performed a descriptive study of notifiable infectious diseases among foreigners reported from 2004 to 2017 in China using data from the Chinese National Notifiable Infectious Disease Reporting System (NNIDRIS). Demographic, temporal-spatial distribution were described and analyzed. Results: A total of 67,939 cases of 33 different infectious diseases were reported among foreigners. These diseases were seen in 31 provinces of China and originated from 146 countries of the world. The infectious diseases with the highest incidence number were human immunodeficiency virus (HIV) of 18,713 cases, hepatitis B (6,461 cases), hand, foot, and mouth disease (6,327 cases). Yunnan province had the highest number of notifiable infectious diseases in foreigners. There were different trends of the major infectious diseases among foreign cases seen in China and varied among provinces. Conclusions This is the first description of the epidemiological characteristic of notifiable infectious diseases among foreigners in China from 2004 to 2017. These data can be used to better inform policymakers about national health priorities for future research and control strategies.
