Pneumonectomy is known as an effective treatment of lung cancer, lung tuberculosis, and damaged lung. But the incidences of complications and mortality are significantly higher in patients undergoing pneumonectomy than those undergoing lobectomy. The complication rate within 30 days after pneumonectomy is 11%-49% and the mortality is 3%-25%. Mortality of right pneumonectomy is triple that of left pneumonectomy. Postpneumonectomy complications include cardiopulmonary failure, bronchopleural fistula and postpneumonectomy syndrome. Besides the symptomatic treatment, which includes flushing drainage, plugging and operation, observation and prompt diagnosis are necessary for prevention. This review is focused on the prevention and treatment of complications after pneumonectomy.
Objetive To investigate the clinical characteristics, diagnosis, and treatment for diffuse alveolar hemorrhage. Methods The clinical data of 17 patients admitted to respiratory ICU with diffuse alveolar hemorrhage from July 1998 to May 2008 were reviewed. Results In the 17 cases, Wegener granulomatosis accounted for 6 cases, microscopic polyangiitis for 3 cases, systemic lupus erythematosis for 4 cases,mitral stenosis for 2 cases, and idiopathic pulmonary hemosiderosis for 1 cases. Clinical presentations included fever ( 76. 4% ) , hemoptysis( 47% ) , anaemia ( 100% ) , dyspnea ( 100% ) , hypoxaemia ( 100% ) ,and elevated total count of white blood cells ( 76. 4% ) . The titer of antineutrophil cytoplasmic antibody ( c-ANCA, p-ANCA) was 1∶( 46. 0 ±3. 7) , 1 ∶( 108. 0 ±16. 1) , respectively. Hemoglobin was ( 78. 0 ±2. 4) g/L. Bronchoalveolar lavage fluid presented with blood accounted for 35. 3% . Siderophages was found in all cases. Computed tomography showed areas of consolidation interspersed with areas of ground-glass attenuation and reticular interstitial opacities. Mortality was 29. 4% . Conclusions Diffuse alveolar hemorrhage is an acute life-threatening event. The clinical presentations of hemoptysis, dyspnea, and anaemia, and chest imaging studies provide clues to diagnosis of diffuse alveolar hemorrhage. Corticosteroids and immunosuppressive agents have proven effective in diffuse alveolar hemorrhage.
Objective To observe the clinical characteristics and influencing factors of post-stroke epilepsy. Methods Our research wasaretrospective study, the data came from the information of patients diagnosed with post-stroke epilepsy from our hospital on October 2000 to December 2014 withatotal of 160 cases. With the general collection of clinical data, including gender, past history, clinical manifestations, laboratory examinations and treatment informations. Results The shortest time of post-stroke seizures were occur immediately, the longest was 15 years after the stroke. Peak onset is as early as onset of stroke immediately, late-onset seizures after stroke peaks between 6 months to 1.5 years. 59 patients occurred early epileptic seizures, partial seizures were the most common, accounting for 47.46%; 101 patients occurred late epilepsy, generalized tonic-clonic seizures were the most common, accounting for 56.44%. 25% of patients wereasingle-site lesions, the most common site was temporal lobe; 75% of patients were multifocal lesions. Most were located in the temporal lobe, frontal lobe and the basal ganglia. 42 cases of patients performed EEG, 30 patients (71.43%) of the EEG abnormalities, including 22 cases (73.33%) recurrent epileptic seizures; 12 cases (28.57%) patients with an edge or normal EEG, including 3 cases (25%) relapsed. 54.38% patients with drug therapy to single-agent therapy, two patients with refractory epilepsy to be combination therapy. Conclusions This group of post stroke epilepsy patients were more common as late-onset epilepsy, early onset of stroke peaks is the first day, and delayed the onset of the peak after stroke is within 6 months to 18 months. Lesions in the cortex:alarge area and multiple lesions were risk factors for post-stroke epilepsy, cortical damage to the temporal lobe is most prevalent. 71.43% of patients may have abnormal EEG, EEG abnormalities have higher relapse rate in patients with epilepsy.
ObjectiveTo understand the status of Roux-en-Y gastric bypass (RYGB) surgery for treating type 2 diabetes mellitus, and to summarize its effectiveness and existing problems. MethodThe related literatures which discussed the treatment for type 2 diabetes mellitus by RYGB were reviewed and analyzed. ResultsThe therapeutic effect of RYGB for type 2 diabetes mellitus with obesity was tentatively confirmed.But the underlying mechanism was unclear.And there was no standard length of exclusion of the Roux loop and biliopancreatic loop.Postoperative long-term effect was unknown.Whether RYGB was suitable for non-obese type 2 diabetes mellitus that needed further to be rese-arched. ConclusionsThe mechanism of RYGB surgery in treatment for type 2 diabetes mellitus is complex.With the progress of basic and clinical research, the improvement of surgical technique, the elucidation of the mechanism, the affirmation of the long-term effect, and there are more benefits in patients with type 2 diabetes mellitus.
ObjectiveTo examine the characteristics of Rhodococcus equi (R. equi) infection for better awareness of this disease.MethodsThe clinical data of a patient with pulmonary abscess caused by R. equi after renal transplantation were reported. We also reviewed the reports of infections caused by R. equi.ResultsThe clinical manifestations and laboratory examination of the patient were consistent with the characteristics of R. equi infection. The growth of R. equi was found in sputum and blood culture. The follow-up data showed that the treatment was effective. Literature search identified 23 similar patients. In all the 24 patients (containing this one), the time of infection after renal transplantation ranged from 4 months to 11 years. There were 21 patients with cumulative pulmonary infection, and 10 patients had a clear epidemiological history of direct or indirect contact with horses. Eighteen patients improved after regular antibacterial treatment or surgical treatment.ConclusionsOpportunistic infections caused by R. equi mainly affect transplant recipients and other patients with lower immunity. Infections caused by R. equi may affect many organ systems with various manifestations. The optimal therapy is not established due to the rarity of this infection. Clinicians should select antibiotic agents rationally based on antimicrobial susceptibility testing and treatment response of patients.
ObjectiveTo explore the diagnosis and treatment features of parathyroid carcinoma (PTC). MethodsThe clinical data of 7 cases of parathyroid carcinoma treated from January 1993 to April 2014 were analyzed retrospectively. ResultsAll of the 7 patients had symptoms of hyperparathyroidism. Four patients had palpable neck mass. The average serum calcium level of preoperation was 3.07 mmol/L (2.35-4.98 mmol/L). The average parathyroid hormone (PTH) level was 1 181.5 pg/mL (78.4-2 061.7 pg/mL), which elevated 17 times the upper limit of normal. One case had operation in other hospital and six cases in Jishuitan hospital. The tumors located in the left inferior parathyroid gland in 3 cases, 2 cases of right lower parathyroid, and right superior parathyroid gland in 1 cases. One case underwent parathyroidectomy, parathyroidectomy including ipsilateral thyroid lobe or part of it was performed in 5 cases. Of 5 cases, 1 case was added central compartment lymphadenectomy. Three cases of postoperative tumor recurrence underwent reoperation, of which 1 case recurred 3 times. Two cases died. The remining 5 had survived until now, had survived for 5 years in 3 cases. ConclusionsA comprehensive approach with clinical presentation, serum calcium and PTH levels, B-ultrasonography, 99Tcm-MIBI, intraoperation aberrant findings, and histopathology offers help to accurate diagnosis of parathyroid carcinoma. Surgery is en bloc resection of the primary lesion. Recurrence needs reoperation, and long-term follow-up is advised.
ObjectiveTo summarize the clinical manifestations and treatment of plasma cell mastitis. MethodsWe retrospectively analyzed the diagnosis and treatment of 53 patients with plasma cell mastitis admitted into the hospital between January 2008 and December 2014. ResultsTwelve patients with nipple discharge underwent mammary gland segment resection in which the complete discharging tube system and part of the normal gland were resected. In the 26 patients with inflammatory masses, 12 had acute inflammation with mass formation who were treated with abscess incision drainage and silver alginate wound dressing before second-stage lesion resection. Fourteen patients with only local swelling, tenderness and no abscess formation underwent lesion resection after the abscesses were reduced by combined traditional Chinese medicine (TCM) and western medical treatment. Seven patients with painless mass all had abscesses in the areola area, among whom 5 had complete inflammatory capsule and they underwent lumpectomy. Two patients had cheese-like tissue beside the abscess, and they underwent segmental resection. In the 8 patients with chronic fistula, one at the age of 51 was cured by simple mastectomy after recurrence, and the other 7 underwent lesion resection after combined TCM and western medical treatment. All the 53 patients were diagnosed to have plasma cell mastitis by surgical biopsy, and they were all cured with no recurrence 6 months after surgery. Conclusions Plasma cell mastitis is usually misdiagnosed because of its diversified clinical manifestations. For patients whose lesion is large and not confined, it's better for them to receive combined TCM and western medical treatment. Surgical time and approach should be chosen appropriately. Surgical lesion resection is the only method for complete treatment in patients with plasma cell mastitis.
ObjectiveTo investigate the etiology, clinical features and treatment of familial exudative vitreoretinopathy (FEVR) secondary glaucoma. MethodsA retrospective clinical study. From January 1, 2016 to January 1, 2022, 15 patients (17 eyes) were diagnosed with FEVR secondary glaucoma in Beijing Tongren Hospital, Capital Medical University were included in the study. All patients underwent systematic ophthalmological evaluation. According to the patient's age, visual acuity, intraocular pressure, anterior segment, vitreous body and retina condition, the choice of translimbal lensectomy combined with vitrectomy, goniectomy, cyclophotocoagulation, intravitreal injection of anti-vascular endothelial growth factor (VEGF) treatment were chosen. The follow-up time was 3 to 37 months. The clinical characteristics of the affected eye, and the changes of intraocular pressure, anterior chamber depth and complications after surgery were observed. ResultsAmong the 15 patients, there were 11 males with 13 eyes, and 4 females with 4 eyes. Age was 6.14±7.37 years old. FEVR stages 2B, 3B, 4A, 4B, 5A, and 5B were 1, 1, 5, 6, 3, and 1 eye, respectively. The intraocular pressure of the affected eye was 42.74±9.06 mm Hg (1 mm Hg=0.133 kPa). All eyes had shallow anterior chamber and angle closure, anterior or posterior iris adhesions, lens opacity, retinal detachment, iris neovascularization in 4 eyes, and vitreous hemorrhage in 2 eyes. Sixteen eyes were treated with translimbal lensectomy combined with vitrectomy and goniotomy, of which 8 eyes were treated with anti-VEGF treatment; 1 eye was treated with cyclophotocoagulation combined with anti-VEGF treatment. After operation, the intraocular pressure of 16 eyes returned to normal range, and the depth of anterior chamber of 16 eyes returned to normal, and no obvious complications occurred. ConclusionsThe main etiology of secondary glaucoma in FEVR is the structural and functional abnormalities of the anterior chamber and angle, which are found in the 2B and above stages of FEVR. The lensectomy and vitrectomy via limbal approach can effectively control the intraocular pressure and restore the anterior chamber, with no serious complications.
Acute kidney injury (AKI), as a complex and severe kidney disease, has always been the hotspot of research. The epidemiological research of AKI in China has made significant progress, including initially reports on the domestic incidence of AKI, geographical distribution and risk factors; however, accompanying challenges like AKI prevention and treatment emerge. For improvement of the diagnosis and treatment of the AKI, this article summarizes and analyses the two challenges: early warning biomarkers and AKI treatment strategies, based on new ideas and research progress. The aim is to make Chinese nephrology scholars and specialists realize the focus of AKI prevention and protection of renal function, to standardize the treatment strategy of AKI, and to put forward the direction of future research.
Objective To observe the clinical effects of vitreoretinal surgery for myopic foveoschisis, evaluate the visual prognostic factors. Methods Twentyseven eyes of 23 patients with myopic foveoschisis underwent vitreoretinal surgery were analyzed retrospectively. All the patients had undergone the examinations of best corrected visual acuity (BCVA), intraocular pressure, slit lamp microscope, direct ophthalmoscope, binocular indirect ophthalmoscope, A or B ultrasonic scan and optical coherence tomography (OCT). Follow-up duration varied from 6 to 36 months, with the mean of (19.4±10.03) months. The visual acuity, retinal reattachment and the complications were observed. Logistic regression analysis was performed to predict the prognosis of visual acuity. Results Twentyone eyes (7778％) were anatomically reattached, six eyes (2222%) were not anatomically reattached. Postoperative BCVA improved in 24 eyes (8889％), reduced or remained unchanged in three eyes (11.11％). No ocular complications such as fundus hemorrhage, low or high intraocular pressure, endophthalmitis were found. The preoperative BCVA （OR=9.11, P=0.007）, axial length （OR=0.31, P=0.038） and the photoreceptor inner and outer segment (IS/OS) junction line continuity （OR=4。32，P=0.001） are closely related to visual prognosis. Conclusions Vitreoretinal surgery is an effective approach to treat myopic foveoschisis with both anatomical and visual improvement. The preoperative BCVA, axial length and IS/OS line continuity are closely related to visual prognosis.
