Prediction of early death after therapeutic hepatic arterial embolisation.

A consecutive series of 14 patients with hepatic malignant disease treated by palliative hepatic arterial embolisation was reviewed. Twelve patients had hepatic pain from their tumour and two were suffering from the carcinoid syndrome. Six patients died within four weeks of the procedure (group 1) and eight survived for at least 10 weeks (group 2). Factors were sought that might permit prediction of a high risk of early death (group 1). The pre-embolisation angiograms reviewed by a "blind" observer showed no differences in vascularity or tumour size between the groups and no difference in the extent of arterial occlusion after embolisation. The portal vein was patent in all patients. No significant difference was seen between the groups in the pre-embolisation biochemical values, with the exception of lower serum albumin concentrations and higher alkaline phosphatase activities in group 1. All those who died early had serum alkaline phosphatase activities of 45 KAU or above, while six of the eight who survived longer had activities below this value (p less than 0.02). These findings suggest that serum alkaline phosphatase activity of 45 KAU or more (normal range 3-13) might alone be a useful predictor of early death. Stepwise discriminant analysis using a weighted combination of serum alkaline phosphatase activity and albumin concentration predicted the outcome in all but one of the patients studied (p less than 0.002).     

Multimodality palliative treatment of (111)In-pentetreotide negative/(123)I-MIBG positive metastatic carcinoid - a case report

Patients with carcinoid tumours frequently present with metastatic disease. There are only a few therapeutic options for these patients, and the main goal of palliative treatment is to reduce symptoms and thus to improve quality of life. Current therapy includes surgical resection, hepatic artery embolisation, chemotherapy and somatostatin analogue treatment; however, all these options have limitations. It seems probable that therapeutic modalities based on radiopharmaceuticals may provide better therapy, not only in relation to symptom reduction but may also improve patient survival. In this case report we present a 46-year-old woman with a symptomatic carcinoid, who at the time of diagnosis had liver and abdominal lymph node metastases, the primary tumour being located in the terminal ileum. (111)In-pentetreotide scanning was negative, whereas (123)I-MIBG scanning showed high avidity in the tumour tissue. After right hemicolectomy, two courses of (131)I-MIBG treatment were given (12.95 GBq and 12 GBq, respectively). After the second dose of (131)I-MIBG temporary pancytopenia was present. Octreotide therapy was given empirically only for a short time and was stopped because of drug intolerance. The patient underwent tricuspid and pulmonary valve replacement because of her carcinoid heart disease, followed by two courses of embolisation of liver metastases. While (131)I-MIBG therapy reduced the patient's symptoms of flushing and diarrhoea, there has not yet been any effect on tumour response or 5-HIAA production. This case illustrates the multimodality and multidisciplinary approach to such patients.     

Towards a more rapid diagnosis of rapidly progressive glomerulonephritis.

An attempt was made to provide simple practical guidelines to alert general practitioners to the diagnosis of rapidly progressive glomerulonephritis and lead to early referral to hospital. The duration of illness before referral to this hospital and its effect on outcome in patients with crescentic nephritis were assessed retrospectively from the case notes of 24 patients referred over two years. Four patients had Goodpasture''s syndrome, 11 Wegener''s granulomatosis, seven microscopic polyarteritis, and two idiopathic progressive glomerulonephritis. The duration of symptoms before referral to the local hospital was similar in the four groups of patients and varied from one week to 28 months (mean 10 months). The duration of stay in the local hospital was two, nine, 11, and 180 days in the patients with Goodpasture''s syndrome and a mean of four days (range one to eight) in those with Wegener''s granulomatosis and 10 days (one to 18 days) in those with microscopic polyarteritis. In the local hospital the diagnosis was based on the results of renal biopsy and detection of antibodies to glomerular basement membrane in two patients with Goodpasture''s syndrome and on the results of renal biopsy in seven of the other patients aided by the detection of antibodies to the cytoplasm of neutrophils (ANCA) in 10. Three of the 24 patients died and four required maintenance haemodialysis. Patients who present to their general practitioners with persistent non-specific symptoms should have a urine dipstick test and then blood tests and emergency referral to hospital if necessary. Hospital physicians should be aware of the speed and accuracy with which current assays can confirm a diagnosis of rapidly progressive glomerulonephritis.     

Cocaine: its use in otolaryngology

A review of 120 patients who had a discharge diagnosis of intermediate coronary syndrome showed 12 patients with documented transient ST elevation during spontaneous rest pain consistent with Prinzmetal''s angina. Coronary arteriography showed severe proximal occlusive coronary atherosclerosis in nine of the patients, and normal or minimal disease in the other three patients. In two of these three, there was documented coronary arterial spasm with reproduction of symptoms during arteriography. Although a shorter history of chest pain, presence of an old myocardial infarction and a positive finding on electrocardiogram treadmill test tended to predict the patients with severe occlusive coronary artery disease, these methods were inadequate to select candidates for arteriography. All patients responded well to nitroglycerine while in the hospital. Five of the nine patients with coronary artery disease had coronary bypass operations, with two excellent, two fair and one poor result. One of the three patients with normal findings on coronary arteriograms died with refractory ventricular arrhythmia six months after study. The other two have had good-to-moderate relief of symptoms on long-acting vasodilators and propranolol. Current concepts of the syndrome of Prinzmetal''s angina and ST elevation are reviewed. It appears that this syndrome has a wide spectrum of clinical presentations and coronary arteriographic anatomies.     

Day-night variations of serum interleukin-6 in patients with severe obstructive sleep apnea syndrome before and after continuous positive airway pressure (CPAP)

Obstructive sleep apnea syndrome (OSAS) causes intermittent hypoxia and increases in sympathetic activity and contributes to cardiovascular disorders. Interleukin-6 (IL-6) is one of the important proinflammatory cytokines. We examined the levels of serum IL-6 concentrations in nine patients with severe OSAS at four different clock times during the 24 h before and after three months of continuous positive airway pressure (CPAP) therapy. Serum IL-6 levels were significantly reduced after CPAP therapy by 46% (6.2+/-1.0 vs. 3.3+/-0.4 pg/ml, p<0.005). No significant 24 h variation of serum IL-6 in severe OSAS patients was found before CPAP; however, a significant 24 h variation of serum IL-6 was found after CPAP. Intermittent hypoxia during sleep may contribute to systemic inflammation and result in an elevation of serum IL-6 in severe OSAS patients.     

Serum prostaglandin F2α concentration in the carcinoid syndrome

Using specific radioimmunoassay procedures we measured prostaglandin F₂α (PGF₂α) and 13, 14-dihydro-15-keto prostaglandin F₂α (PGF₂α metabolite) in 12 patients with carcinoid tumors. Although PGF₂α and PGF₂α metabolite were each modestly elevated in 17% of the patients the magnitude of the elevation did not correlate with the symptoms of the carcinoid syndrome. The 24 hour urinary 5-hydroxyindoleacetic acid excretion showed a good correlation with carcinoid symptoms while the serum serotonin concentration showed a fair correlation with carcinoid symptoms. We conclude that serum elevation of PGF₂α is not a frequent occurrence in patients with the carcinoid syndrome.     

131I]metaiodobenzylguanidine therapy in carcinoid tumors.

Our experience with [131I]metaiodobenzylguanidine (131I-MIBG) therapy in two patients with carcinoid tumor is described. These patients were selected because of multiple areas of uptake on 131I-MIBG scan, consistent with the extent of the disease. Both patients presented diarrhea and liver metastases. Para-aortical lymphonodes and skeletal metastases were present in the first and the second patient, respectively. Previous treatment involved r-alpha-interferon, surgery or radiotherapy. In both cases 131I-MIGB therapy was started in December 1990 and is still continuing. No haematologic or hepatic side-effects have been observed. Mild hypotension (90/60 mmHg) occurred in one patient during the first course of therapy and was resolved by corticoid treatment. A stabilization of disease and a progressive reduction of diarrhea have been observed in both patients. In the second patient an initial decrease in liver metastases was confirmed by ultrasonography 7 months after the beginning of therapy.     

Day‐Night Variations of Serum Interleukin‐6 in Patients with Severe Obstructive Sleep Apnea Syndrome before and after Continuous Positive Airway Pressure (CPAP)

Obstructive sleep apnea syndrome (OSAS) causes intermittent hypoxia and increases in sympathetic activity and contributes to cardiovascular disorders. Interleukin‐6 (IL‐6) is one of the important proinflammatory cytokines. We examined the levels of serum IL‐6 concentrations in nine patients with severe OSAS at four different clock times during the 24 h before and after three months of continuous positive airway pressure (CPAP) therapy. Serum IL‐6 levels were significantly reduced after CPAP therapy by 46% (6.2±1.0 vs. 3.3±0.4 pg/ml, p<0.005). No significant 24 h variation of serum IL‐6 in severe OSAS patients was found before CPAP; however, a significant 24 h variation of serum IL‐6 was found after CPAP. Intermittent hypoxia during sleep may contribute to systemic inflammation and result in an elevation of serum IL‐6 in severe OSAS patients.     

Neuropeptide K-(1-24)-peptide: storage and release by carcinoid tumors

An antiserum directed against the COOH-terminal region of neuropeptide K-(1-24)-peptide that shows only 0.5% reactivity with neuropeptide K has been used in radioimmunoassay to study the posttranslation processing of human beta-preprotachykinin. A primary midgut carcinoid tumor contained high concentration of substance P (2970 pmol/g), neurokinin A (3660 pmol/g) and neuropeptide K-(1-24)-peptide (3430 pmol/g) but only a very low concentration (less than 5 pmol/g) of intact neuropeptide K. Neuropeptide K-(1-24)-peptide was also detected in extracts of metastatic tumor tissue from four patients with midgut carcinoid tumors. The amino acid sequence of tumor neuropeptide K-(1-24)-peptide was identical to that predicted from the nucleotide sequence of a human beta-preprotachykinin cDNA. The fasting plasma concentration of neuropeptide K-(1-24)-peptide was elevated in a patient with the carcinoid syndrome (821 fmol/ml compared with less than 18 fmol/ml in healthy subjects) and rose approximately 2-fold after intravenous pentagastrin. The study has demonstrated that the Lys25-Arg26 bond in neuropeptide K (corresponding to Lys96-Arg97 in the precursor) is an important processing site in human beta-preprotachykinin.     

Balloon dilatation of the aortic valve for inoperable aortic stenosis.

The place of balloon dilatation of the aortic valve in the treatment of calcific aortic stenosis is controversial. Thirty two patients (mean age 76) in whom valve replacement was contraindicated were followed up for three to 24 months (mean 8); 25 were in functional class III or IV according to the New York Heart Association''s classification. Major complications of the procedure occurred in four patients. Echocardiography and Doppler studies were performed before operation and before discharge in 28 patients, and the area of the valve was measured again six to 50 (mean 23) weeks after operation in 11 patients. The peak to peak aortic pressure gradient fell from a mean of 65 (SD 24) to 46 (20) mm Hg, but the area of the aortic valve, measured by Doppler echocardiography, in 18 patients showed a modest but significant increase, from 0.61 (0.16) to 0.74 (0.23) cm2. One month after dilatation, 29 patients were alive, of whom 17 had improved symptoms. Only two had lasting clinical benefit. Sixteen patients died, 12 of a cardiac cause. The estimated one year survival rate was 49%. Six patients underwent or required valve replacement because of persisting symptoms. In view of its limited long term efficacy balloon dilatation of the aortic valve should be used only for patients with severe symptoms whose life expectancy is limited by other disease or who are considered to be unsuitable for valve replacement. It may have a role in improving the condition of patients who present with cardiogenic shock or pulmonary oedema before valve replacement is undertaken.     

Acute admissions of patients with sickle cell disease who live in Britain.

All acute admissions of patients with sickle cell disease who lived in the London borough of Brent and attended this hospital were analysed for a period of one year. Sixty three of the 211 patients who were followed up by the haematology department required 161 acute admissions during the year. Most admissions (126) were for the 42 patients with homozygous sickle cell disease; 147 (91%) were for vaso-occlusive episodes, 142 of which were for painful crises, three for cerebrovascular accidents, and two for renal papillary necrosis. Preschool children with sickle cell disease were admitted predominantly with limb pain, whereas in schoolchildren and adults the incidence of trunk pain was higher. Twenty four of the 93 episodes of trunk pain culminated in an episode of severe visceral sequestration usually affecting the lungs, the liver, or the mesenteric circulation. Two patients died: an 18 month old baby with an acute splenic sequestration crisis and a 19 year old man with a severe girdle syndrome (sickling in the mesenteric circulation, liver, and lungs). Infective episodes were rare (11 episodes) but severe: one haemophilus meningitis, two salmonella infections, and three aplastic crises due to parvovirus infections. The average duration of the hospital stay was 7.4 days per admission. It is concluded that because sickle cell disease causes appreciable morbidity in older children, adolescents, and adults a systematic approach to management is needed to deal with acute episodes such as sequestration syndromes.     

Primary hepatic carcinoid tumor

Primary hepatic carcinoid tumor is rare and poses a challenge for diagnosis and management. We presented a case of primary hepatic carcinoid tumor in a 53-year-old female with a complaint of right upper abdominal pain. Computer tomography scans revealed a hypervascular mass in segment 4 of the liver. An ultrasonography-guided biopsy showed a carcinoid tumor. No other lesions were found by the radiological investigations. Surgery resection was performed and histopathological examination revealed a primary hepatic carcinoid tumor. Three years later, recurrence was found and transcatheter arterial chemoembolization was performed. After transcatheter arterial chemoembolization, the patient has been free of symptom and had no radiological disease progression for over 6 months. Surgical resection combination with transcatheter arterial chemoembolization is effective to offer excellent palliation.     

Preliminary results of [131I]metaiodobenzylguanidine treatment in metastatic carcinoid tumors.

The successful use of [131I]metaiodobenzylguanidine (131I-MIBG) in the scintigraphic localisation and treatment of several tumors deriving from neuroectoderm has led us to its application in metastatic carcinoid tumors. We selected five patients (two men and three women; age range 53-79 years) who showed progression of the disease with severe related symptoms, poor response to traditional therapy and a good uptake of 131I-MIBG in neoplastic tissue. A cumulative radioactivity of 3.7-22.2 GBq was given. All patients had a clear subjective improvement with a better quality of life for a period of 2-36 months, sometimes accompanied by decreased 5-hydroxyindoleacetic acid urinary excretion. Results concerning objective remission of the disease were unsatisfactory. No remarkable early or late side-effect was noted. We believe 131I-MIBG is useful for symptomatic treatment of metastatic carcinoid in seriously ill patients too. Different treatment schedule and recruitment of patients with less advanced disease could make pathological remission a possible goal.     

Rheumatic symptoms after cardiac surgery: a prospective study.

The incidence of different types of shoulder pain after open heart surgery was studied prospectively. Of 101 patients studied, 45 developed rheumatic symptoms during the first six weeks after the operation. Thirty eight patients reported pain in the region of the shoulder girdle with no loss of shoulder function (postpericardiotomy rheumatism). Three of these patients also had features compatible with the postpericardiotomy syndrome (fever, malaise, or pleuritic chest pain), and seven developed the syndrome without pain in the shoulder girdle. Of these 10 patients, one had generalised myalgia. Postpericardiotomy rheumatism alone was not associated with increased inflammation (measured by the erythrocyte sedimentation rate and concentration of C reactive protein); immunological tests including measurement of antibodies to cardiac muscle yielded inconclusive results. Replies to a postal questionnaire showed that symptoms of postpericardiotomy rheumatism were present for over three months in 18 patients and for six months or longer in 14. In view of the large number of patients now having open heart surgery postpericardiotomy rheumatism should be considered when patients report pain around the shoulders so that it is not misdiagnosed as angina.     

Biobehavioral treatment of excessive micturition

Five patients with excessive frequency of micturition were provided with a behavioral therapy — biofeedback treatment. The patients, three females, 22, 27, and 37 years of age, reported symptoms of dyspareunia and excessive frequency for 2–4 years; the two males included a 51-year-old who reported excessive frequency and pain in the bladder region for four years, and a 36-year-old who reported excessive frequency for 24 years. All of the patients had undergone traditional evaluations and treatments by urologists, yet their symptoms persisted although no organic pathology could be detected. Record-keeping data over a 4-week pre-treatment baseline indicated an average daily frequency of voiding of 15.7; the pain in the region of the bladder reported by three patients was an average of 5.2/day on a scale of 0–10.The treatment consisted of 3 phases throughout which all patients recorded: time of urinary urge, time of urination, and level of tension. The phases included: (1) four-week baseline; (2) biofeedback-assisted relaxation training at home using portable skin resistance trainers; (3) self-control using relaxation to gradually increase the delay between the time of the urge to urinate and the actual urination; and (4) follow-up, during which time the record-keeping was continued. An average of 11.4 sessions were required until the patients reported normal voiding frequency (average of 8.6/day) and absence of pain. Follow-up data ranging from 4 to 36 months indicated normal frequency was maintained in four of the five patients. The remaining female maintained the gains for five months, but then reverted to her baseline level at eight months.     

Chronic fatigue syndrome beginning suddenly occurs seasonally over the year

The fact that many patients with chronic fatigue syndrome (CFS) have an infectiouslike sudden onset to their illness has led to the hypothesis that CFS is a medical illness. If CFS were, on the other hand, a psychiatric disorder related to symptom amplification, one would expect illness onset to occur randomly over the calendar year. This study tested that hypothesis with 69 CFS patients whose illness was on the more severe side of the illness spectrum; all patients reported sudden illness onset with the full syndrome of sore throat, fatigue/malaise, and diffuse achiness developing over no longer than a 2-day period. Date of illness onset was distinctly nonrandom. It peaked from November through January and was at its lowest from April through May. These data support the hypothesis that an infectious illness can trigger the onset of CFS. (Chronobiology International, 17(1), 95-99, 2000).

Chronic fatigue syndrome (CFS) is a medically unexplained illness characterized by fatigue, pain, and cognitive complaints. Because many of the symptoms of CFS overlap with those of depression, some argue that CFS is a somatic manifestation of depression or a somatoform disorder. Komaroff (1988) has suggested that, because CFS patients develop their illness suddenly with an infectiouslike presentation, this supports an underlying medical etiology to the illness. If CFS were indeed triggered by an infectious illness, one would expect to find the dates of sudden illness onset to occur more often in months when viral infections are common. If CFS were a somatoform disorder, one would expect a random distribution of dates of illness onset across the calendar year. Since our center has a large number of CFS patients who report a sudden infectiouslike illness onset, the purpose of this paper was to determine if the dates of illness onset occurred randomly or nonrandomly across the calendar year.     

Correction of pincer-nail deformity using dermal grafting

Pincer-nail syndrome has been described as distortion in the shape of the nails with excessive transverse curvature of the plate that increases from proximal to distal, leading to pinching and loss of soft tissue in the affected digit, resulting in severe pain. Many treatments have been recommended, but an effective long-term method that preserves the nail matrix has not been described. A method of dermal grafting under the nail matrix is described, and the results of treatment of six digits are reported. Five women and one man with an average age of 52 were treated. The affected digit was the thumb in four patients and the great toe in two patients. Follow-up averaged 25 1/2 months. The results were good in all cases with only one side of one nail remaining slightly curved. Pain was relieved in all cases, and complete adherence of the new nail plate occurred. Dermal grafting seems to provide excellent long-term treatment of the pincer-nail deformity with preservation of the nail matrix.     

Four drug-HAART in primary HIV-1 infection: clinical benefits and virologic parameters

BACKGROUND: From a theoretical standpoint, primary HIV infection (PHI) represents a great chance to modify the natural history of the disease. In this study we purposed a four drugs regimen with zidovudine, lamivudine, ritonavir and saquinavir to treat aggressively the infection and achieve a complete immune reconstitution. METHODS: This is an Italian multicentric open label study. Adult patients with PHI were eligible for the study if they met at least one clinical criterion and one laboratory criterion of the following. Clinical criteria: Signs and symptoms of acute retroviral syndrome within the past 70 days, exposure to HIV-1 within the last 3 months, a preceding negative antibody test within the past 6 months. Laboratory criteria: Detectable p24 antigen with neutralization in serum; detectable HIV-RNA in plasma; indeterminate Western blot test with negative or low positive value HIV antibody in ELISA test. RESULTS: Since April 1997 to April 1999 40 patients with PHI have been enrolled; 80% of this cohort referred symptoms related to acute antiretroviral syndrome. Treatment has been withdrawn in 17 patients (12 for intolerance, 3 for toxicity and 2 for failure). At baseline the mean CD4+ T cells count and CD4/CD8 ratio were 537 (range 55-1287) and 0.58 (range 0.1-1.03) and the mean plasma HIV-RNA level was 5.9 log copies/ml (range 3-7.15). Plasmatic HIV-1 RNA levels of all patients dropped below 200 copies/ml in 68% of patients at week 12, 81% at week 24, 93% after 12 months and 100% after 18 months. Immunological parameters have been improved and have achieved normal range since 6th month. CONCLUSIONS: A rapid virologic suppression and immunological reconstitution are associated with PHI therapy. However early treatment should be weighted against the potential disadvantages such as immediate adverse events (intolerance and drug toxicity) and long term manifestation (metabolic disorders).     

Chronic pain as a reticular formation syndrome

Evidence was previously presented to support the thesis that chronic pain is activated by neuronal elements that make up the multisynaptic short axon core of the reticular system (Andy and Peeler 1985). The present thesis, that chronic pain is a reticular formation syndrome, is based on a retrospective analysis of four patients with chronic pain who were successfully treated with a lesion in the anterior thalamus and stimulation electrode implants in the posterior thalamus and pontomesencephalic brain stem. The reticular formation was the common underlying anatomic substrate at those three sites. In addition to chronic pain, all the patients had other symptoms attributable to other body organs and systems. The number and type of symptoms that made up the syndrome differed between patients. Symptoms making up the core of the syndrome were pain, anxiety, nervousness, insomnia, and depression. Experimental and clinical findings are briefly presented to demonstrate the various reticular formation sites, pragmatically considered "reticular functional systems," from which symptoms may arise. It is hypothesized that the symptoms are recruited by a low threshold "pain oscillator" that is generated at one reticular site and subsequently permeates the rest of the reticular system. Therapeutic stimulation inactivates the low threshold system by "jamming" it.     

Hepatic artery ligation in treatment of carcinoid syndrome.

Summary: In a patient with malignant carcinoid syndrome with metastasis to the liver, cardiac lesions, pulmonary hypertension, pellagra-like skin lesions and depression developed. Her disability progressed despite medical therapy and two courses of chemotherapy. The primary tumour had been resected but the metastatic mass in the liver could not be resected because of its anatomic position. The dramatic improvement after hepatic artery ligation was correlated with urinary 5-hydroxyindole acetic acid excretion.
