Objective To study problems related to drug-induced liver lesion caused by antituberculotic therapy (DLL).Methods Totally, 172 cases of DLL occurred in 1 464 patients with pulmonary tuberculosis after antituberculotic therapy, hospitalized during January 1995 to December 2002, were reviewed and analyzed retrospectively.Results Patients aged 20 to 60 years with DLL by antituberculolis therapy accounted for 70.3% of the total. Symptoms of digestive tract and change in liver function usually occurred within 8 weeks of intensive treatment (73.8%), and discontinuation of autituberculotic drugs was not needed for the mild cases, but needed for the severe cases with liver protective therapy. In total, 157 of the 172 cases (91.3%) recovered completely and 13 case improved (7.6%), two cases deteriorated and discharged, and doses of autituberculotic drugs should be reduced or stopped in 41 cases (23.8%) affecting their treatment efficacy.Conclusions DLL was liable to occur in patients of pulmonary tuberculosis with antituberculotic therapy, especially in the elderly men with body weight less than 50 kilograms, those with previous liver damage or infected with hepatotropic virus, alcohol drinking, complicated with extrapulmonary tuberculosis, with combination of isoniazid rifampicin and pyrazinamide.

Ommaya reservoir implantation is generally used in the treatment of hydrocephalus and intraventricular drug administration. Ommaya reservoir implantation in the subarachnoid space of the spinal cord for the intrathecal drug administration has not been carried out in China, and only several reports can be retrieved from PubMed. About 60%-90% of untreated patients with spinal muscular atrophy type 2 (SMA2) who survive to adulthood often have complex scoliosis and joint deformities. Nusinersen is an effective drug for the treatment of SMA2. And the route of administration is intrathecal injection, which is difficult for patients with severe scoliosis. This article summarizes the process of Ommaya reservoir implantation and postoperative drug administration in a patient with complex scoliosis type SMA2, which provides a new method for clinical treatment of this disease.

Familial pheochromocytoma belongs to autosomal dominant inheritance, and has complex and variable clinical manifestations. A child with bilateral PHEO was admitted to our hospital. His grandmother, father and brother were all diagnosed with PHEO, and his aunt was diagnosed with paraganglioma. The child underwent laparoscopic left partial adrenalectomy and open surgery for the contralateral tumor, and was in good postoperative condition. The blood pressure returned to normal and there was no local recurrence and metastasis during the follow-up of 8 months after the second operation.

【Objective】 To investigate the effects of preoperative ureteroscopy (URS) on the intravesical recurrence (IVR) in patients with upper tract urothelial carcinoma (UTUC) after radical nephroureterectomy (RNU). 【Methods】 The clinical data of 241 UTUC patients treated during May 2012 and Jan.2020 in the Second Hospital of Laozhou University were retrospectively analyzed. The patients were divided into URS before RNU group (URS group) and non-URS before RNU group (non-URS group). The cumulative IVR rate, progression-free survival (PFS) and overall survival (OS) after RNU were compared, and the survival curve was drawn. Cox proportional hazards models were used to assess risk factors affecting IVR. 【Results】 Of the 241 patients, 64 (26.6%) were included in the URS group and 177 (73.4%) in the non-URS group. In the URS group, 49 underwent biopsy and 15 did not. All patients were followed up for a median of 44 (3 to 122) months, with a median time to recurrence of 12 (3 to 56) months. IVR occurred in 18 patients (28.1%) in the URS group and 25 (14.1%) in the non-URS group. Kaplan-Meier survival analysis showed that the cumulative IVR rate was higher in the URS group than in the non-URS group (all P<0.05), regardless of whether patients had a history of bladder cancer (BC) or not, while PFS was lower in the URS group than in the non-URS group (P=0.007). Cox multivariate regression analysis showed that URS (P=0.031) and complicated renal pelvis tumor and ureteral tumor (P=0.004) were independent risk factors for IVR. 【Conclusion】 Preoperative URS increases the incidence of IVR in patients with UTUC, and routine preoperative use of URS is not recommended.
