RESUMO
Objective:To investigate the etiological spectrum, clinical features, and surgical treatment of patients with Cushing's syndrome (CS) who underwent adrenal surgery.Methods:From August 2002 to August 2022, the clinical data of 985 patients with Cushing's syndrome who underwent surgical treatment in the department of urology, Peking Union Medical College Hospital were retrospectively analyzed. There were 210 males and 775 females. The average age was 43.33±13.49 years old. The age of males was older than that of females (45.53±14.39 vs. 42.68±13.16 years, P=0.016). The principle of preoperative surgical method selection for patients in this group was described as follow. For adrenocorticotropin (ACTH) independent CS, adrenal tumor resection was considered for unilateral solitary lesions and unilateral adrenalectomy was considered for unilateral multiple lesions. For bilateral lesions, the larger tumor was removed first, and the contralateral operation was decided according to the follow-up results. Patients with suspicion of cortical cancer are subjected to R0 resection, and open surgery was performed if the tumor diameter is≥6 cm. The clinical characteristics of CS patients were summarized. The clinical symptom characters, etiology spectrum and the corresponding selection principles of surgical methods were analyzed. Results:Among the 985 cases, ACTH-independent CS accounted for 92.8% (914/985), and ACTH-dependent CS accounted for 7.2% (71/985). According to the postoperative pathological results, ACTH-independent CS was the most common, among which adrenal adenoma was the most common 75.94% (748/985), PBMAH 11.37% (112/985), Cushing's disease 4.26% (42/985), PPNAD 3.25% (32/985), EAS 2.94 (29/985), cortical carcinoma 2.23% (22/985). In terms of clinical manifestations, full moon face, bloody face, buffalo back, central obesity and weight gain were more common. The incidence of the above single symptoms was >30%. In terms of hormone secretion, the cortisol level of ACTH-dependent CS patients was significantly higher than that of ACTH-independent CS ( P<0.001). Cortisol [(16.61±6.78) μg/dl] and 24h-UFC [103.65 (59.83, 175.70) μg/24h] in patients with subclinical cortical adenoma were lower than those in other types of patients ( P<0.001). Among the patients with bilateral adenomas, 4 patients underwent simultaneous resection of bilateral adrenal tumors due to severe CS symptoms, and the remaining 74 patients underwent two-stage simple tumor resection, total adrenalectomy or subtotal adrenalectomy according to the size and number of tumors. Of the 22 patients with cortical carcinoma, 2 patients underwent R0 resection after neoadjuvant therapy with mitotane after being diagnosed by needle biopsy due to local infiltration of the tumor. In patients with EAS and Cushing's disease, 62.07% (18/29) and 23.81% (10/42) were treated with simultaneous bilateral target gland resection due to severe CS symptoms, respectively. In 112 cases of PBMAH and 32 cases of PPNAD, the initial treatment was unilateral adrenalectomy or subtotal adrenalectomy, and the follow-up was continued to decide whether to perform contralateral adrenalectomy or subtotal adrenalectomy. Conclusions:The etiological spectrum of CS patients admitted to the urology department is different from that of the overall CS, and is dominated by adrenal disease, and Cushing's disease is rare. Due to the different etiological spectrum, the patient's symptom spectrum is different, and difficulty in squatting and fracture are rare. The main treatment for unilateral adrenal disease is tumor resection or unilateral adrenalectomy. For ACTH-dependent CS in bilateral lesions, bilateral adrenalectomy is recommended, and hormone supplementation is recommended after surgery. For ACTH-independent CS, unilateral adrenalectomy is recommended first, and individualized treatment plans are formulated based on the results of follow-up.
RESUMO
Aims:The etiological spectrum and clinical profile of admitted patients presenting with pancytopeniawere studied. Study Design:This was a prospective study conducted on 200 patients presenting to the Department of Medicine, Department of Oncology and the Allied Specialities of Medicine, Dayanand Medical College and Hospital, Ludhiana and were found to have pancytopenia during hospital stay.Results:Mean age of the patients was 45.69 ± 17.05 years with maximum number of patients (23%) in the age group of 51-60 yearsand 119 patients were males and 81 patients were females.Most common physical finding was pallor (95%), followed by splenomegaly (22%) and hepatomegaly (17%). Total of107 patients were vegetarians (53.5%) and 93 patients (46.5%) were non-vegetarians. Mean hemoglobin was 7.16 ± 2.04 g/dl, mean total leucocyte count was 2.51 ± 1.02 x 103/cu.mm, mean platelet count was 54885.37 x 103/ul ± 40320.96 and mean the absolute neutrophil count was 1.59 x 103 /cu.mm ± 0.84. Ten patients of pancytopenia were because of tropical fever which included 4 cases of dengue, 3 cases of malaria, 2 cases of enteric fever and 1case of mixed infection (malaria + scrub typhus).Viral markers were positive in 14 out of the 63 patients tested. Out of these 14 patients, 4 were HBsAg reactive, 7 were HCV +ve and 3 were HIV +ve. Most common red blood cell picture on peripheral blood film was normocytic normochromic (34.5%), followed by mixed morphology (33.5%). Macrocytic and microcytic morphology was seen in 19.5% and 12.5% of the patients respectively. Hypercellular marrow was seen in 82 patients (42.9%), normocellular marrow was seen in 58 patients (30.3%) and hypocellular marrow was seen in 51 patients (26.7%). The most common cause of pancytopenia in this study was megaloblastic anemia in 59 patients (29.5%), the 2nd common cause was leukemias in 28 patients (14%) and the 3rdcause was aplastic anemia in 22 patients (11%). Drug induced pancytopeniawas seen in 21 patients (10.5%) and hypersplenism in 9 cases (4.5%).Conclusion:This study has helped us in knowing the various etiologies of pancytopeniain this hospital. Megaloblastic anemia was the most common etiology in this study followed by leukemiasand aplastic anemia. The study helped us in understanding of the age and gender distribution, the hematological parameters, the peripheral blood film in pancytopenia and the bone marrow picture in these patients.
RESUMO
Objective In order to investigate etiology and molecular-epidemiological characteristics of enterovirus associated encephalitis (EAE) in Zhejiang,2008-2012.Method Cerebrospinal fluid and stool specimens were collected from suspected EAE patients,who were admitted to our hospitals.RD and Hep-2 cell lines were used to isolate enterovirus (EV).Serotypes of these EV isolates were identified through neutralization test by using serotype specific anti-sera.VP 1 genes of these isolates were sequenced,compared and used for the construction of phylogenetic tree.Results 127 (20.6％) human enterovirus (HEV) strains were isolated from 616 samples,which were collected from 610 patients.Serotypes of these EV isolates,including 60 coxsackievirus (CV),and 67 Echovirus (E) appeared to be CVA9,CVB1,CVB3-5,E3,E4,E6,E9,El4,E25 and E30,respectively.Predominant EV serotypes on EAE from 2008 to 2012 were seen as CVB3,CVB5,E6,E30 and E30,respectively.The full length of VP1 genes from different EV isolates was between 834 and 918 nucleotides.The VP1 gene similarities between these isolates and the reference strains were from 76.7％ to 85.0％ (nucleotides level) and 91.1％ to 97.9％ (amino acids level).The VP1 genes from E6 serotype isolates appeared most diverged,reaching 20.4％ (nucleotides level) attd 4.8％ (amino acids level).Based on the generated phylogenetic tree,all the EV isolates were fallen on the same branch of HEV-B,and the isolates in the same serotype formed one sub-branch,suggesting there existed geographical and temporal effects.E6 isolates diverged into two branchlets.Conclusion EVs from HEV-B were the etiologic agents for EAE in Zhejiang province from 2008 to 2012.All these EV isolates showed 12 serotypes,with predominant isolates varied every year.E30 was determined as the most dominant serotype while serotype E6 diverged into two sub-genetypes.
