Increased incidence of menstrual abnormalities and hysterectomy preceding primary biliary cirrhosis.

A study was performed to assess the incidence of previous hysterectomy and dilatation and curettage among women with primary biliary cirrhosis. In 87 patients with primary biliary cirrhosis hysterectomy or dilatation and curettage had been performed significantly more often than among 100 age matched normal controls and 80 age matched patients with chronic active hepatitis or alcoholic liver disease. Among the 47 patients with primary biliary cirrhosis who had undergone hysterectomy or dilatation and curettage operations had been performed at a mean of 10.7 years and 13.2 years, respectively, before the onset of disease. The main indication for hysterectomy among patients with primary biliary cirrhosis and controls was menorrhagia. These menstrual disorders may be a consequence of high concentrations of oestrogens in patients with primary biliary cirrhosis.     

Long-term survival of human skin allografts in patients with immunosuppression

Severe burn patients lack adequate skin donor sites to resurface their burn wounds. Patients with severe burn injuries to areas such as an entire face are presently reconstructed with skin grafts that are inferior to normal facial skin. This study was designed in part to determine whether human skin allografts would survive, repopulate, and persist on patients with immunosuppression and after discontinuation of immunosuppression. Small split-thickness skin grafts were synchronously transplanted at the time of renal transplantation from six renal transplant donors to recipients. All six patients were immunosuppressed with the usual doses of renal transplant immunosuppressants (methylprednisolone, cyclosporine, prednisone, and azathioprine). The skin allografts were biopsied when rejection was suspected and at various intervals. Special histologic studies were performed on skin biopsy specimens. Class II DNA tissue typing was performed on transplanted and autogenous skin biopsy specimens of four patients. Fluorescent in situ hybridization was performed successfully on skin biopsies of four patients' transplanted skin and on two of these four patients' autogenous skin. All six human skin allografts sustained a 100 percent take and long-term clinical survival. DNA tissue typing performed on skin allograft biopsy specimens from patients taking immunosuppressants all revealed donor and recipient cells. DNA tissue typing performed on autogenous skin biopsies from the same patients all revealed only recipient cells. Fluorescent in situ hybridization performed on allograft and autogenous specimens from patients taking immunosuppressants revealed transplanted donor cells with rare recipient cells in the allograft and only recipient cells in the autogenous skin. This study of six patients proves that it is possible for human skin allografts to survive indefinitely on patients taking the usual dosages of immunosuppressants used for renal transplantation. There was minimal repopulation of skin allografts by autogenous keratinocytes and fibroblast while patients were taking immunosuppressants. Immunosuppression was discontinued in two patients after renal transplant rejection after 6 weeks and 5 years. When immunosuppression was discontinued after 5 years in one patient, the skin allograft cells were destroyed and replaced with autogenous cells, but the skin graft did not reject acutely and persisted clinically. It is hypothesized that the acellular portion of the skin allograft was not rejected acutely because of relatively low antigenicity and because it acted as a lattice for autogenous cells to migrate into and replace rejected allograft skin cells. No chimerism was seen in autogenous skin in the skin-renal transplant patients in this study.

经皮介入封堵冠状动脉-肺动脉瘘治疗分析

目的:分析冠状动脉-肺动脉瘘(coronary artery-to-pulmonary artery fistula,CPAF)行经皮介入封堵治疗的可行性、安全性及疗效。方法:回顾性分析长海医院心内科于2009年7月至2016年2月之间接受经皮介入封堵术的58例CPAF患者的临床资料,排除合并其他复杂心脏病变而需要外科手术治疗的患者。结果:58名CPAF患者经介入封堵均获成功,平均植入封堵材料(2.35±0.87)枚。24名(41.38%)患者成功封堵后残余分流立即消失,34名(58.62%)患者仍有少量分流。未出现手术相关并发症。术后随访2~61个月,无出血、缺血等并发症。随访造影显示,其中3名(5.17%)患者出现了大量再通,后者随后均接受了再次封堵术并成功封堵。结论:经皮介入封堵CPAF切实可行,但应选择适宜患者,且需要经验丰富的术者操作。经治疗后冠状动脉瘘可能出现再通,因此对这些患者应进行随访造影或其他影像学检查。     

Hyperreactivity of the bronchial tree in patients with hay fever before and after immunotherapy

Immunotherapy with Pollinex was performed in 46 patients with hay fever. Hyperreactivity of the bronchi determined with inhalation histamine test was noted in 36% of the patients. Histamine test was positive in 24% of patients treated with Pollinex. The difference was statistically insignificant.     

Immunohistochemical study of vascular endothelial growth factor (VEGF), tumor suppressor protein (p53) and intercellular adhesion molecule (ICAM-1) in the conjunctiva of diabetic patients

Summary The expression pattern of VEGF, p53 and ICAM-1 was studied in conjunctiva of diabetic patients with and without retinopathy. All patients underwent a complete ophthalmic examination, including retinal fluorescein angiography. Indirect immunoperoxidase method was performed on 20 eyes of 20 patients with type II diabetes without DR and on 5 eyes of 5 patients with PDR. A control study was performed on 6 normal conjunctiva undertaken during cataract surgery. Immunoreactivity of VEGF, p53 and ICAM-1 was found in epithelial, fibroblast and vascular endothelial cells. For the same duration of diabetes, a strong to moderate or weak immunoreactivity was observed in the conjunctiva of patients without retinopathy. In patients with PDR, the expression was strong for all these proteins. The immunoreactivity was correlated between VEGF, p53 and ICAM-1. In the normal conjunctiva, a weak to negative immunostaining was observed. The presence of these proteins in the conjunctiva of diabetic patients without retinopathy may add new data in the pathogenesis of diabetic retinopathy. Further studies are needed to confirm this hypothesis.     

Changes in bone mineral density in patients with prostate cancer treated with androgen deprivation therapy

Osteoporosis is a complication of permanent androgen deprivation in men with prostate carcinoma, following either bilateral orchiectomy or treatment with GnRH agonists. The present approach to the problem of osteoporosis includes prevention, adequate follow-up and appropriate treatment as an imperative of contemporary urological and endocrinological management of these patients. Bone densitometry was performed in 18 patients who were on GnRH agonists treatment during 1-3 years. The patients under therapy were followed clinically, PSA (prostate-specific antigen) values were determined and bone scintigraphy was performed. The bone mineral density values in 13 patients indicated osteopenia, whereas in one patient the finding was compatible with osteoporosis. Four patients had normal bone mineral density findings. Bone densitometry should be performed before initiation of treatment with GnRH agonists in order to quantify the therapy-related bone loss. Prevention of development of osteoporosis and its complications depends on the assessment of pharmacological treatment in this group of patients, including e.g. bisphosphonates and possible intermittent androgen deprivation.     

西妥昔单抗联合FOLFIRI 与单用FOLFIRI 方案治疗转移性结直肠癌近 期疗效的对照研究

目的:比较西妥昔单抗(爱必妥)联合FOLFIRI化疗方案与单用FOLFIRI化疗方案治疗转移性结直肠癌患者的临床疗效和毒副反应。方法:回顾性分析2008年1月至2011年11月解放军总医院经组织病理学证实的46例转移性结直肠癌患者临床资料,其中西妥昔单抗联合FOLFIRI化疗方案组22例,单用FOLFIRI方案组24例,观察比较两组方案的近期疗效和不良反应。结果:两组方案治疗转移性结直肠癌的客观缓解率(CR+PR)分别为41.6%和12.5%,其中联合治疗方案治疗效果明显优于单用FOLFIRI化疗方案,两组比较差异有统计学意义(P<0.05)。患者出现的不良反应有痤疮样皮疹、腹泻、骨髓抑制、恶心呕吐、脱发等。除痤疮样皮疹和腹泻外,两组患者毒副反应无显著性差异。结论:西妥昔单抗联合FOLFIRI化疗方案治疗K-Ras基因野生型转移性结直肠癌近期疗效显著,毒副反应较单用FOLFIRI方案无明显增加,患者可以耐受。     

Beneficial Effect of Endocrinologist-Performed Ultrasonography on Preoperative Parathyroid Adenoma Localization

ObjectiveTo evaluate whether endocrinologist-performed ultrasonography improves the localization of parathyroid adenomas in patients with primary hyperparathyroidism.MethodsWe performed a retrospective analysis of consecutive patients with primary hyperparathyroidism due to a single adenoma who underwent surgery at the Dokuz Eylul University Hospital in Izmir, Turkey, between January 2000 and January 2008. Data regarding the localization of adenomas were obtained from surgical reports. Neck ultrasonography was performed in all patients as first-line imaging. Parathyroid ultrasonography was performed by a staff radiologist between January 2000 and December 2004. Beginning January 2005, parathyroid ultrasonography was performed blindly by an endocrinologist in addition to the staff radiologist. In the case of discordant preoperative localization between the endocrinologist- and radiologist-performed ultrasonography, surgery was performed according to the technetium Tc 99m sestamibi (MIBI) scan and endocrinologist-performed ultrasonography localization results.ResultsA total of 156 patients with primary hyperparathyroidism due to a single adenoma were included. Of the 156 patients, 139 also underwent MIBI scan. Ultrasonography localized 102 parathyroid adenomas (65%). The accuracy of the ultrasonography was improved in patients who underwent endocrinologist-performed ultrasonography. Endocrinologist-performed ultrasonography localized the adenoma correctly in 19 patients for whom the staff radiologist had reported a negative or unsuccessful localization. When ultrasonography results were combined with the MIBI scan findings, parathyroid adenomas were again more likely to be localized in patients who underwent operation after January 2005 and thus had endocrinologist-performed ultrasonography.ConclusionOur results suggest that endocrinologist-performed ultrasonography improves the preoperative localization of parathyroid adenoma.

Value of injection hepato-lymphography during percutaneous transhepatic cholangiography in patients with cholestasis

Injection hepatography (IH) was made in 278 patients with cholestasis to study the drainage function of the liver. In 208 cases. IH was performed as a test during percutaneous transhepatic cholangiography (PTHC). The hepatic lymph pathways were imaged in 167 (60%) patients. Images of the biliary tract were obtained in 245 (88.1%) patients with cholestasis, it being not dilated in 34 (12.2%) patients. The fact that hepatolymphography may be performed during PTHC as an independent test permits verification of hepatic lymph circulatory disorders that are an index of the rate of inflammation in the organ.     

The acutely occluded left main coronary artery culprit in cardiogenic shock and initial percutaneous coronary intervention: a substudy of the Manitoba "no option" left main PCI registry

We aim to describe the in-hospital outcomes of the first reported Canadian cohort of patients with cardiogenic shock and acute myocardial infarction (MI) due to acute and total occlusion of the left main coronary artery, treated with initial percutaneous coronary intervention (PCI). Acute left main thromboses with cardiogenic shock were identified (N?= 8) from a retrospective consecutive cohort of high risk left main PCI (N?= 56) performed at our institution from 2004-2009. The mean age was 62.3?± 13.2?years, with 6 (75%) male patients. Successful PCI was performed in all patients, with thrombectomy utilized in 4 patients (50%), stenting in 7 patients (88%), and intra-aortic balloon pump augmentation in 7 patients (88%). Two patients (25%) required extracorporeal membrane oxygenation (ECMO) and 2 other patients required ventricular assist devices. Post-PCI coronary artery bypass grafting (CABG) was performed for 2 patients (25%). The mean SYNTAX score was 26.6?± 10.5. The mean logistic EuroSCORE was 30.4?± 12.6%. In-hospital mortality occurred in 3 patients (38%). Acute left main occlusion is a rare but devastating presentation of myocardial infarction, invariably with cardiogenic shock. Emergent PCI may be an effective method to acutely revascularize this subset of patients; however, aggressive post-PCI care including ECMO, CABG, and ventricular support may be required to improve patient survival.     

支纤镜肺活检联合刷检与经皮肺穿刺活检对肺周围型病变诊断价值的研究

目的:探讨两种肺检查方法对肺部周围常见疾病的诊断价值.方法:回顾性分析胸片和CT检查发现肺周围型病变的43例患者,在经支气管肺活检联合刷检和/或CT引导经皮肺穿刺活检病理确诊阳性率.结果:43例患者共行33次支气管肺活检联合刷检,26例获取标本成功,阳性诊断率为78.79%.经皮肺穿刺活检17例,全部获取标本成功,1例患者因取材量少,病理结果无诊断意义,阳性诊断率为94.11%,两者结合诊断率97.67%.结论:经支气管肺活检联合刷检与经皮肺穿刺活检对肺周围型病变诊断都是安全、有效、准确、损伤小的诊断方法,两种方法联合使用可明显提高诊断率.     

A study of impaired fibrin polymerization in patients with the nephrotic syndrome.

Clotting studies have been performed on 64 consecutive patients with nephrotic syndrome. The thrombin time was prolonged in 59. Fibrin polymerization was studied in 42 of the 59 patients with a prolonged thrombin time and an abnormality was present in 22. There was a significant correlation between the prolongation of the thrombin time and impairment of polymerization (p = 0.018). No correlation was found between these two parameters and the patient's sex, age and drug therapy. Furthermore there was no correlation with the prothrombin time, APTT, fibrinogen, FDP, antithrombin III and platelet counts. There was however a significant negative correlation between the thrombin time and the serum albumin level (p less than 0.05). No abnormal bleeding was observed during or after renal biopsy in these patients. Renal biopsy may be performed safely despite the grossly prolonged thrombin time and abnormal fibrin polymerization in patients with the nephrotic syndrome.     

Early Endoscopy of Oesophagus,Stomach, and Duodenal Bulb in Patients with Haematemesis and Melaena

Oesophago-gastro-duodenoscopy was successfully performed in 196 of 208 patients admitted with haematemesis or melaena, or both. A precise visual diagnosis was made in 80% of all patients and in 96% of those where the final diagnosis lay within the oesophagus, stomach, and first two parts of the duodenum. Bleeding oesophagitis was more common and bleeding duodenal ulcer less common than in other series using mainly radiology. Altogether, 26% of all patients with endoscopically-proved duodenal ulcers were bleeding from another site, and 15·4% of all patients had more than one lesion. This fact, and inability to detect surface lesions limits the value of acute barium radiology, which was performed in only 81 patients. Accurate diagnosis should lead to better understanding of individual lesions and more rational management of individual patients. Where a good service is available oesophago-gastro-duodenoscopy should be performed on all bleeding patients within 24 hours of admission.     

Dissecting aortic aneurysm and contrast magnetic resonance angiography

The propose of the present work is to study the potential of the 3-D contrast MR-angiography (MRA) in diagnosis of aortic dissection. The studied group consisted of 45 patients who as expected might have aortic dissection. 15 patients was observed in dynamics after surgical treatment. Total number of me performed contrast-MRA was 72. MRA has been performed on 1.5T MR tomograph Magnetom Vision (Siemens) with the of ultrafast sequenses Fisp and turbo-flash. Aortic dissection was diagnosed in 18 patients. The method of ce-MRA enables to make a precise diagnose of acute and chronic aortic dissection. This method is used for a dynamic follow up of the patients after the performed surgery.     

Surgical treatment of submucous cleft palate: a comparative trial of two modalities for palatal closure

Submucous cleft palate is a congenital malformation with specific clinical and anatomical features. It can be present with or without velopharyngeal insufficiency. Surgical treatment of this malformation is indicated only when velopharyngeal insufficiency has been demonstrated. This article compares two modalities of surgical treatment for submucous cleft palate. The first includes a minimal incision palatopharyngoplasty, as described in a previous report. The second combines the first technique with additional individualized velopharyngeal surgery (individualized pharyngeal flap or sphincter pharyngoplasty) performed simultaneously. The individualized part of the procedure was selected and performed according to the findings of videonasopharyngoscopy and multiview videofluoroscopy, as reported previously. Two hundred and three patients with submucous cleft palate were studied from 1990 to 1999. Videonasopharyngoscopy and multiview videofluoroscopy demonstrated velopharyngeal insufficiency in 72 patients, who were randomly divided into two groups. Those in group 1 (n = 37) underwent a minimal incision palatopharyngoplasty. Patients in group 2 (n = 35) also underwent that procedure but simultaneously received individualized pharyngeal flap or sphincter pharyngoplasty, according to the findings of videonasopharyngoscopy and multiview videofluoroscopy. The median age of the patients from both groups was not significantly different (p > 0.5). The frequency of residual velopharyngeal insufficiency after palatal closure was not significantly different in both groups of patients (14 percent versus 11 percent; p > 0.5). The mean size of the gap at the velopharyngeal sphincter during speech was not significantly different in both groups of patients before surgery (23 percent versus 22 percent; p > 0.5). After the surgical procedures, there was a nonsignificant difference between both groups of patients in mean residual size of the gap in cases of velopharyngeal insufficiency (7 percent versus 8 percent; p > 0.5). It seems that minimal incision palatopharyngoplasty is a safe and reliable procedure for palatal closure in patients with submucous cleft palate. The use of additional individualized velopharyngeal surgery performed simultaneously did not seem to decrease the frequency of residual velopharyngeal insufficiency. Moreover, the residual size of the gap at the velopharyngeal sphincter was not significantly reduced when an additional surgical procedure was performed simultaneously with palatal closure.     

Dysfunction in a prefrontal substrate of sustained attention in schizophrenia

Regional brain metabolism was measured in normal subjects and patients with schizophrenia while they performed an auditory discrimination task designed to emphasize sustained attention. A direct relationship was found in the normal subjects between metabolic rate in the middle prefrontal cortex and accuracy of performance. The metabolic rate in the middle prefrontal cortex of patients with schizophrenia, even those who performed as well as normals, was found to be significantly lower than normal and unrelated to performance. The findings point to a role of the mid-prefrontal region in sustained attention and to dysfunction of this region in schizophrenia.     

Adriamycin in the combined chemotherapy of small-cell lung cancer

The results of combined chemotherapy and chemoradiotherapy of 158 patients with small cell lung cancer are presented. Adriamycin was used as one of the components of the induction chemotherapy of 98 out of the 158 patients. Chemoradiotherapy (nitrosomethylurea, methotrexate, CCNU, adriamycin, vincristine, DTIC, radiotherapy) was performed according to 4 schemes and combined chemotherapy (cyclophosphamide, adriamycin, methotrexate, or CCNU, cyclophosphamide, methotrexate plus adriamycin, vincristine, natulan) was performed according to 2 schemes. The total efficacy (complete and partial regression) of the 6 schemes averaged to 80 per cent. The number of patients with complete regression amounted to 29 per cent. Long-term survival for more than 2 years was observed in 17 per cent of the patients. No signs of metastases or relapses for 5 years were recorded in 6 per cent of patients. Adriamycin is one of the most active antitumor drugs in combined chemotherapy and chemoradiotherapy of small cell lung cancer.     

Aesthetic eyelid ptosis correction: a review of technique and cases

Upper eyelid ptosis can present both functional and aesthetic problems. Because proper correction of ptosis can be difficult to achieve, numerous surgical procedures have been developed. Plication of levator aponeurosis can be combined with aesthetic blepharoplasty and facial rejuvenation procedures to successfully address ptosis. The authors assessed the effectiveness of levator aponeurosis plication for correction of acquired upper eyelid ptosis in patients presenting for concomitant cosmetic facial procedures. The medical records of 74 consecutive patients (68 women and six men) who had upper eyelid ptosis correction in conjunction with cosmetic facial procedures from January of 1994 to January of 2000 were reviewed. During this period, 400 endoscopic forehead lifts and 479 face lifts were performed. The correction was performed through an external upper blepharoplasty approach removing an ellipse of skin and orbicularis muscle. Once the orbital septum was opened, a plication of the levator aponeurosis was accomplished by one or more horizontal mattress sutures of 6-0 clear nylon (with the first bite placed at or just medial to the vertical level of the pupil). The average follow-up period was 14 months. Long-term correction of the ptosis was excellent. The complications were minor, with the most common occurrence being asymmetry. Revisions were performed on only four patients. Correction of ptosis can be performed safely and effectively in conjunction with periorbital and facial rejuvenation. The technique described is simple, reliable, and reproducible.
