Objective:To investigate the clinical characteristics, diagnosis and treatment of chronic natural killer cell lymphoproliferative disease (CLPD-NK) associated peripheral neuropathy.Methods:The clinical data of 1 case of CLPD-NK associated peripheral neuropathy who was hospitalized in Beijing Chaoyang Hospital on March 17, 2022 were reported. The clinical characteristics, laboratory examinations, nerve biopsy, treatment and prognosis of CLPD-NK associated peripheral neuropathy were summarized in combination with domestic and foreign literature reports.Results:This patient was a 62-year-old woman with progressive weakness and numbness of limbs. Nerve conduction test revealed peripheral nerves injures of limbs. No abnormality was found in a routine biochemistry test of cerebrospinal fluid. Lymphocyte infiltration was found in the nerve bundle of sural nerve with CD56(+), TIA-1(+). After prednisone combined with cyclophosphamide treatment, her weakness and numbness of limbs were relieved, and the white blood cells count decreased. A total of 10 cases of CLPD-NK associated peripheral neuropathy were summarized, including 5 males and 5 females. The median onset age was 64 years. The peripheral blood white cells count was 5.50×10 9/L-24.66×10 9/L, the lymphocytes count was 1.54×10 9/L-32.00×10 9/L, and cerebrospinal fluid protein increased in 3 cases. Biopsy of sural nerve showed NK cell infiltration in all patients. Immunosuppression was the main treatment, and most patients had a good prognosis. Conclusions:CLPD-NK associated peripheral neuropathy is rare. Peripheral nerve biopsy is the important diagnostic method. Corticosteroids and immunosuppressants are effective for this disease.

Objective To discuss the surgical strategy and clinical effects of robotic assisted laparoscopic antegrade inguinal lymphadenectomy for penile cancer.Methods We retrospectively analyzed the clinical data and surgical strategy on the 7 cases,who undergoing robotic assisted laparoscopic antegrade inguinal lymphadenectomy,from August of 2016 to August of 2017.The mean age of 7 patients was (49.7 ± 7.5) years old,ranged from 40 to 62 years old,the mean BMI was (27.97 ± 3.86) kg/m2,ranged from 21.76 to 33.21 kg/m2 . There were 4 cases of T1,2 cases of T2,1 case of T3,1 case of N1,3 cases of N2,3 cases of N3 according to TNM stages.Preoperative preparation was as follows,preoperative cardiopulmonary assessment,inguinal and pelvic CT or MRI,ultrasound of lower extremity venous,bowel preparation.The patients were placed in a supine position,with an indwelling catheter,with the head positioned lower than the hip at an angle of about 15 degrees,legs were spread apart around 45 degrees,and both knees were slightly bent and externally rotated.The da Vinci robotic patient cart was pushed forward between legs of the patient.A blunt separation was carried out between Scarpa's fascia and the surface of the aponeurosis of the obliquus externus abdominis prior,then subcutaneous space was established by a self-made balloon dilatation.Results 7 cases were completed successfully without robot reposition without any conversion.Operative time of each side ranged from 50 to 90 min (70.0 ± 12.5)min.The blood loss of each side was less than 10 ml.In the 7 cases,the number of nodes removed from left inguinal region ranged from 7 to 18 (14.0 ±3.3).The number of nodes removed from right ranged from 5 to 21 (11.0 ± 3.3).Pelvic lymphadenectomy was completed in the meantime by original trocar site on 4 cases.Till now,no perioperative complications,such as flap necrosis,delayed healing of incision,cellulitis,occurred in inguinal region,except lymphorrhagia in 3 cases.During a follow-up within 3-14 months,there was no recurrence or metastasis in 6 cases except one died from tumor progression with systemic metastasis.Conclusions Antegrade inguinal lymphadenectomy for penile cancer by using Da Vinci robotic surgical system is safe and effective.This technique also appears to diminish the wound related complications associate with the standard open approach.Compared with the similar surgery,we conducted bilateral inguinal lymphadenectomy without patient cart reposition,which simplify the procedure and reduce the using of trocar.According to individual clinical conditions,pelvic lymphadenectomy also can be completed in the meantime by original trocar.

Objective Standard neuropsychological assessment plus structural and functional imaging were used in accurate diagnosis of Benson's syndrome (posterior cortical atrophy).Method Serial neuropsychological screening and integrative assessments of visual spatial function, 3D structural MRIimaging and functional FDG-PET imaging were used in two cases of Benson' s syndrome.Results The clinical signs were agnosia, optic ataxia, apraxia, alexia, agraphia and prosopagnosia.MRI imaging revealed bilateral parietal and occipital lobe atrophy.FDG-PET imaging revealed low metabolism in the posterior cortex.The agraphia was constructive: the words were correct but written in the wrong location.Conclusion Standard neuropsychological assessments can recognize the disease nature.When combined with the structural and functional imaging, a correct diagnosis of Benson's syndrome can be made.

Objective To analyse the neuropsychological changing of nonfluent aphasia frontotemporal dementia (nf-FTD) with the FDG-PET, MRI and fMRI. Methods The language and other cognitive function were dynamically estimated by standard neuropsychological assessment which modified by Chinese. Compared with FDG-PET and fMRI, the relationship between the neuropsychologieal changing and the cortex function was studied. Results All the 5 patients met the criteria of nf-FTD by Association for Frontotemporal Dementias, with core syndrome and other supptted syndrome. And still they had the good word reading, calculation by pen, and the un-speechmemory. And they also had the related well living ability. They all had the related cortext metabolism support. Conclusions nf-FTD patients preserve the word reading, visuapacial ability and calculation by pen. These can help us to give the effective advise about the patients training and caring and to give them the chance to show their real social skill.
