Secondary diseases in HIV-infected patients

During the period of 1980-1996 the dispensary observation of 50 HIV-infected patients was carried out. The clinical forms of the infection were distributed among these patients as follows: asymptomatic forms in 18 patients, persisting generalized lymphadenopathy in 8 patients, pre-AIDS in 14 patients, AIDS in 10 patients. Secondary infections were registered at the pre-AIDS stage. Dermatoses, oropharyngeal candidiasis occurred most frequently: in 52% of the HIV-infected patients. Herpes virus infection was registered in 46% of the patients. At the stage of AIDS during the generalized herpes virus and cytomegalovirus infections were registered in 5 and 7 patients respectively. Generalized forms of combined infections (herpes virus + fungi) prevailed, which caused the death of 7 patients at the terminal stage of AIDS.     

HIV infection: the psychological indices at different stages of the disease

The pronounced forms of depression and the levels of neuro-psychical adaptation and subjective control (attitude to the disease) were studied in 27 patients with HIV infection. 14 patients were at stage A, 8 patients were at stage B and 5 patients were at stage C of the CDC classification (1994). Starting from the early stages of the disease, neuro-psychical adaptation disturbances were noted: at stage A 10 patients belonged to group 5 of health, at stage B 8 patients and at stage C 2 patients. Most of the patients (15) had a low level of subjective control, 12 patients exhibited a medium level, which should be taken into consideration in prescribing and carrying out curative and diagnostic procedures.     

131I]metaiodobenzylguanidine therapy in 20 patients with malignant pheochromocytoma.

Twenty patients, 16 male and 4 female (aged 11-76 years), with metastatic pheochromocytoma were treated in our Institution between 1985 and 1990. Metastases occurred in all patients: at presentation in 11 patients, with a 10 to 30 month delay in 7 patients, and 9 and 28 years later respectively in 2 patients. Catecholamines hyperproduction was present in all patients. Metaiodobenzylguanidine (MIBG) uptake was found in 16 patients after a diagnostic dose and only after a therapeutic dose in 1 patient. Surgery was performed on primary tumor (18 patients) and on distant metastases (10 patients). 131I-MIBG therapy was performed in 11 patients, 9 of whom were evaluable. The cumulative activity ranged from 3.7 to 26.3 GBq (100 to 711 mCi) in 1 to 6 courses. We observed symptomatic improvement (5 patients) and partial tumor response in 2 patients, which lasted for 28 and 9 months respectively, terminating with a rapidly progressing disease involving the bone marrow. Stabilisation was observed in 3 patients. Moderate myelosuppression occurred in 4 patients. Fifteen patients died with a median survival of 16 months (range 3-60). Response to therapy was poor and further evaluation of the presently available therapeutic approaches is needed.     

基于听觉刺激的意识障碍患者脑功能连通性研究

目的 目前对意识障碍（DOC）患者的分级评估仍是相关领域的重点和难点。因效性网络可以通过时间序列间的因果关系直观地反映信息传递方向,帮助人们更好地理解患者大脑不同区域之间的信息交互作用。本文结合脑电图和因效性网络探讨听觉刺激下无反应觉醒综合征（VS）患者与最低意识状态（MCS）患者的脑功能连通性差异。方法 共纳入23例DOC患者,采集并分析唤名刺激下的脑电信号,通过多元格兰杰因果方法构建脑功能网络,利用脑网络节点度、聚类系数、全局效率以及因果流向性等参量从脑区之间协同工作的角度对比研究听觉刺激下不同意识水平患者的网络特征。结果 唤名刺激下MCS患者的脑功能连通性强于VS患者,且呈现出因果流向差异,MCS与VS患者四个脑区的信息传递方向均不相同。结论 唤名听觉刺激下MCS患者的信息传递能力强于VS患者;与VS患者相比MCS患者为因果源的电极通道数增多,对其他脑区的信息输出增多。本研究可为DOC患者意识水平的分级评估提供一定的理论依据。     

Analysis of the reasons for not undergoing laser corneal refractive surgery in 611 patients

To determine and analyze the reasons for patients not undergoing laser corneal refractive surgery. A retrospective observational study was conducted to analyze the reasons for not undergoing laser corneal refractive surgery in 611 patients. In this study, 611 (14.34%) among 4,262 enrolled patients did not undergo laser corneal refractive surgery. Among these 611 patients, the common reasons for not undergoing laser corneal refractive surgery were concern about the surgery (366 patients, 59.90%), insufficient corneal thickness (72 patients, 11.78%), too high corneal refractive power (36 patients, 5.89%), dry eye (33 patients, 5.40%), high intraocular pressure (22 patients, 3.60%), poor corrected visual acuity (25 patients, 4.09%), retinal diseases (23 patients, 3.76%) and others (34 patients, 5.56%). The concern about surgery is the primary factor for the patients not undergoing laser corneal refractive surgery.     

Testicular responsiveness to long-term administration of hCG and hMG in patients with hypogonadotrophic hypogonadism

Steroidogenic responsiveness and amelioration of sperm number and motility following long-term intramuscular hCG and hMG administration were evaluated in 18 males with hypogonadotrophic hypogonadism (HH). The patients consisted of 13 patients with isolated gonadotrophin deficiency (IGD) and 5 patients hypophysectomized at an early or middle pubertal period. Basal serum levels of testosterone and 17 beta-estradiol were within prepubertal range in all patients before the treatment. Serum testosterone levels reached the normal adult male levels within 12-24 months of the treatment in only 2 of 7 younger patients and 1 of 6 older patients with IGD, whereas in all hypophysectomized patients serum levels of both testosterone and 17 beta-estradiol increased to the levels found in normal adult males within 6 months of the treatment. The mean peak levels of serum testosterone and 17 beta-estradiol, respectively, during the treatment were 2.1 +/- 0.8 (SD) ng/ml and 10.8 +/- 4.9 (SD) pg/ml in younger patients with IGD, 1.4 +/- 0.9 ng/ml and 9.7 +/- 5.1 pg/ml in older patients with IGD and 6.0 +/- 1.2 ng/ml and 34.2 +/- 14.8 pg/ml in hypophysectomized patients. Quantitative improvement in both sperm density and sperm motility were found in 4 of 7 younger patients, 1 of 6 older patients with IGD and all hypophysectomized patients, but only 3 of hypophysectomized patients (3 of 18 patients) could become fertile.     

Five-and-a-half years' experience with percutaneous retrogasserian glycerol rhizotomy in treatment of trigeminal neuralgia

The results of treating trigeminal neuralgia with percutaneous retroganglionic glycerol rhizotomy in 319 patients from an overall series of 394 patients with 459 operations carried out over a period of 5 1/2 years are reported. Idiopathic trigeminal neuralgia was the diagnosis in 252 patients. 34 patients had trigeminal neuralgia associated with multiple sclerosis. The remaining 33 patients suffered from symptomatic trigeminal neuralgia or atypical facial pain. 230 patients (91.3%) with idiopathic trigeminal neuralgia and 30 patients (88.2%) with multiple sclerosis reported complete freedom from pain. In 12 patients (4.8%) of those with tic douloureux and in 1 patient (2.9%) with multiple sclerosis, pain was alleviated, and the patients required a reduced pharmacotherapy. 10 patients (3.9%) and 3 patients (8.8%) were considered to be treatment failures. The rate of recurrences within the first 2 years was 10.9 and 40.0%, respectively. In the long-term, the rate of recurrences in patients with tic douloureux was 36.9%. 144 patients (45.1%) noticed a hypesthesia. 132 patients (41.4%) had hypalgesia following the procedure, and there was a decrease of symptoms in the long-term observation in 20.0% of the patients. 59 patients (18.5%) developed dysesthesia postoperatively which regressed only to an inappreciable extent in the long-term course. In 16 patients (5.0%) exclusively with a preexisting organic lesion or who had received surgical pretreatment, there was a loss of corneal sensation. The investigation showed on the one hand the effectiveness of the method, but on the other hand also the possibility of marked sensory disorder in selected cases.     

Atrial fibrillation precipitated by acute hypovolaemia.

Six patients with varying degrees of acute cardiorespiratory failure were seen. All patients deteriorated noticeably when rapid atrial fibrillation developed. In all patients intravenous digitalis failed to slow the ventricular response, and in three patients misguided attempts at electrical cardioversion failed. Haemodynamic monitoring showed a normal or low pulmonary artery occlusion pressure in all patients. Controlled expansion of plasma volume was associated with an immediate slowing of the heart rate in all patients, and the heart rate in all patients returned to sinus rhythm within 30 minutes of transfusion. It is suggested that hypovolaemia in critically ill patients may contribute to the development of atrial fibrillation.     

Continuous ambulatory peritoneal dialysis: experience with 22 unselected patients with renal failure.

The present study describes our experience with CAPD in an unselected group of patients presenting with endstage renal failure. Twenty-three consecutive patients were offered CAPD, in-center, and home hemodialysis. Twenty-two patients selected CAPD, including 14 patients more than 60 years of age, four patients with diabetes, and one with multiple myeloma. CAPD training was performed in an out-of-hospital office facility. One patient returned to hemodialysis following the development of resistant Pseudomonas peritonitis, two patients died of a myocardial infarction, and one patient died with a GI bleed. The other 18 patients are doing well. Assessment of 17 patients maintained on therapy for four months or more revealed that the patients are less depressed, less organic, and have fewer physical symptoms than previously reported for a comparable group of patients maintained on hemodialysis for a similar period of time. In conclusion, CAPD can be successfully employed, at least for the initial months of therapy, to treat the vast majority of patients with endstage renal disease. CAPD training and follow-up care can be provided in an out-of-hospital office facility.     

Functional evaluation of the adenohypophysis with metoclopramide in hyperprolactinemic-amenorrheic women in relation to radiological findings on the sella turcica

The responses of the adenohypophyseal hormones to metoclopramide (MCP) were evaluated in hyperprolactinemic women with various radiological findings on the sella turcica. Serum PRL concentrations significantly increased after MCP administration in normal women, hyperprolactinemic patients with normal sella and patients with microadenoma, but not in macroadenoma patients with and without suprasellar expansion (SSE). The PRL response to MCP administration was significantly lower in hyperprolactinemic patients than in normal women. Serum TSH concentrations significantly increased after MCP administration in each group of subjects. The TSH response to MCP was significantly higher in patients with normal sella and patients with microadenoma than in normal women. However, the responses of PRL and TSH to MCP were not significantly different between patients with normal sella and patients with microadenoma. Therefore, they were not considered useful in distinguishing tumorous from nontumorous hyperprolactinemia. Serum LH concentrations significantly increased after MCP administration in patients with normal sella, patients with microadenoma and macroadenoma patients without SSE, but not in normal women or macroadenoma patients with SSE. The LH response to MCP was significantly higher in patients with microadenoma than in patients with normal sella. Serum FSH concentrations significantly increased after MCP administration only in patients with microadenoma. The different responses of the adenohypophyseal hormones to MCP in hyperprolactinemic women with various radiological findings on the sella turcica may be explained by the difference in the hypothalamic dopamine activity and in the impairment of the hypothalamic-pituitary system due to pituitary tumor.     

Role of anti-cyclic citrullinated peptide antibodies in discriminating patients with rheumatoid arthritis from patients with chronic hepatitis C infection-associated polyarticular involvement

This study was performed to assess the utility of anti-cyclic citrullinated peptide (anti-CCP) antibodies in distinguishing between patients with rheumatoid arthritis (RA) and patients with polyarticular involvement associated with chronic hepatitis C virus (HCV) infection. Serum anti-CCP antibodies and rheumatoid factor (RF) were evaluated in 30 patients with RA, 8 patients with chronic HCV infection and associated articular involvement and 31 patients with chronic HCV infection without any joint involvement. In addition, we retrospectively analysed sera collected at the time of first visit in 10 patients originally presenting with symmetric polyarthritis and HCV and subsequently developing well-established RA. Anti-CCP antibodies and RF were detected by commercial second-generation anti-CCP2 enzyme-linked immunosorbent assay and immunonephelometry respectively. Anti-CCP antibodies were detected in 23 of 30 (76.6%) patients with RA but not in patients with chronic HCV infection irrespective of the presence of articular involvement. Conversely, RF was detected in 27 of 30 (90%) patients with RA, 3 of 8 (37.5%) patients with HCV-related arthropathy and 3 of 31 (9.7%) patients with HCV infection without joint involvement. Finally, anti-CCP antibodies were retrospectively detected in 6 of 10 (60%) patients with RA and HCV. This indicates that anti-CCP antibodies can be useful in discriminating patients with RA from patients with HCV-associated arthropathy.     

Efficacy of Chemotherapy Combined with Targeted Arterial Infusion of Verapamil in Patients with Advanced Gastric Cancer

The present study evaluated the efficacy of chemotherapy combined with targeted arterial infusion of verapamil in patients with advanced gastric cancer. Forty patients were enrolled. Targeted arterial infusion of verapamil was done once a month, 3–5 times per patient, along with chemotherapy. After 2 bouts of combined treatment, the efficacy was evaluated. Primary gastric tumor was confirmed in 38/40 patients, and unconfirmed in 2/40 patients due to adhesion of tumors to surrounding tissue. Combined treatment was administered in 38 patients with defined tumors. Complete response to the treatment was in 5/38 (13.1 %) patients, partial response in 27/38 (71.1 %) patients, stable disease in 4/38 (10.5 %) patients, and progressive disease in 2/38 (5.26 %) patients. The effective rate (i.e., complete + partial response) comprised 84.2 %. There were 31 patients with liver metastases; 10/31 (32.3 %) patients showed complete response, 16/31 (51.6 %) patients showed partial response, 3/31 (9.7 %) patients had stable disease, and 2/31 (6.5 %) patients had progressive disease. The effective rate in these patients was 83.8 %. Thirty-seven patients were followed up, and 27/37 (73.0 %) patients were alive for 6 months or longer, 19/37 (51.3 %) for 12 months, 8 (35.1 %) for 18 months, and 8/37 (21.6 %) for 24 months. In conclusion, in patients with advanced gastric cancer, chemotherapy is more effective when combined with targeted arterial infusion of verapamil, leading to extended patients’ survival and improved quality of life.     

幽门螺杆菌感染与慢性口臭关系的初步研究

目的 调查主诉口臭患者的幽门螺杆菌（H．pylori）感染率和主诉消化不良的口臭发生率。方法 研究对象为125例主诉慢性口臭患者和212例主诉慢性消化不良患者。口臭以口气挥发性硫化物（VSC）检测与闻诊联合诊断,H．pylori感染以^14C-尿素呼气试验诊断。结果 125例主诉慢性口臭的患者有87例是真性口臭,其余38例为假性口臭,真性口臭患者的H．pylori感染率显著高于假性口臭（40．2％和13．2％,P〈0．01）。212例主诉慢性消化不良的患者发生口臭105例（49．5％）、感染H．pylori 94例（44．3％）,H．pylori阳性患者的口臭发生率显著高于H．pylori阴性患者（57．5％和43．2％,P〈0．05）。无论何种主诉,大部分口臭患者属于VSC阳性（88．5％）,但H．pylori阳性患者和H．pylor阴性患者口气VSC水平差异无显著性,VSC阳性口臭和VSC阴性口臭的H．pylori感染率差异也无显著性。结论 H．pylori感染可能与口臭的发生有一定关系,但口气VSC并非由H．pylori直接产生。     

Total and subtotal glossectomy: function after microvascular reconstruction

Twelve patients with advanced carcinoma of the floor of the mouth and tongue were treated with total (five patients) or subtotal (seven patients) glossectomy, partial mandibulectomy, and immediate reconstruction with the microvascular composite groin flap. The osteomusculocutaneous groin flap was used in eleven patients, and the osteomuscular flap was used in one patient. The groin musculocutaneous or muscle flap was designed to resemble the shape of the tongue for dynamic food transport, improved swallowing, and acceptable speech. Eight of the 12 patients who survived more than 1 year were evaluated for speech and swallowing. Eight patients were able to speak intelligibly, six patients could tolerate a soft/pureed diet, and two patients were limited to fluids. Cinefluorographic swallow studies using semisolid contrast material showed voluntary active intraoral transport and propulsive pharyngeal emptying without aspiration in six patients with complete flap to palate contact; the remaining two patients were unable to move the intraoral contrast material effectively for swallowing because of poor palatal contact.     

INDICATIONS FOR AND RESULTS FOLLOWING EXPLORATION OF THE COMMON BILE DUCT FOR STONES

Among 100 consecutive patients who had removal or drainage of the gallbladder and exploration of the common bile duct for stones, there were no serious, immediate or late complications and there were no operative deaths. Ninety-six of the 100 patients had stones in the gallbladder, in the common duct, or in both, and 52 of these patients had one or more stones in the common duct.Ten patients died subsequently of unrelated causes. Six patients were lost to followup. Of the 84 patients whose present condition is known, 75 or 89 per cent have had a completely satisfactory result. Six more patients have minor residual symptoms, and for them the result has been classified as good. In three patients, the results were unsatisfactory. Cholangiograms taken before the removal of the T-tube showed residual stones in two patients. In each instance, the stone or stones have been subsequently passed and both patients are in excellent condition.     

Effects of the histone deacetylase inhibitor ITF2357 in autoinflammatory syndromes

We explored the effects of the oral histone deacetylase (HDAC) inhibitor ITF2357 in patients with autoinflammatory syndrome. In this prospective open-label pilot study, eight patients were enrolled; one patient with tumor necrosis factor receptor-associated periodic syndrome (TRAPS), three patients with hyper-IgD and periodic fever syndrome (HIDS) and four patients with Schnitzler syndrome were closely followed during 90 d of ITF2357 treatment. Three patients with Schnitzler syndrome and one TRAPS patient experienced a partial remission. In four patients, there was no effect. In HIDS patients, there was a tendency toward a higher attack frequency and increasing attack severity. In two patients (one TRAPS and one HIDS), we observed a decrease of acute-phase response without signs of clinical improvement. One patient with Schnitzler syndrome showed a partial response despite an ongoing acute-phase response. In conclusion, ITF2357 monotherapy was able to induce partial response only in patients with Schnitzler syndrome and no response in patients with HIDS.     

Comparison of serum free thyroxine measurements by chemiluminescence and equilibrium dialysis

A study of 239 patients compared free thyroxine (FT4) measurements made by equilibrium dialysis (ED) with measurements made using the Magic Lite FT4 chemiluminescence (Cl) immunoassay (Ciba Corning Immunodiagnostics). Patient groups: 41 normals; 27 hyperthyroid; 29 hypothyroid; 37 sick euthyroid; 10 chronic renal failure (CRF) and 25 pregnant patients; 13 oestrogen; 10 heparin; 12 salicylate; and 9 dilantin-treated patients; 3 lipaemic; 5 haemolysed; 6 hyperbilirubinaemic patients; 6 low thyroid binding protein (TBP) and 6 high TBP level patients. The two assays gave comparable results in most groups. Both assays tended to give elevated values in heparinized patients but FT4–ED results were more obviously affected. Pregnant patients and women on oral oestrogen had higher mean values with FT4–ED. In both assays the sick euthyroid and CRF patients had mean FT4 values similar to healthy euthyroid patients; the range of values in sick euthyroid and CRF patients was similar in both assays but wider than in healthy euthyroid patients. A supplemental study of 81 unselected acutely ill patients using FT4–Cl alone confirmed the wider range of values to be anticipated in sick euthyroid patients.
