Abstract
Brucellosis is a zoonosis that is emerging in some regions of the world. Although brucellosis is a disease of obligatory declaration and is not eradicated in Portugal, no prevalence data is available in this country. In this study, we retrospectively analyzed the data available at the Reference Laboratory at the Portuguese National Institute of Health during the past 7 years (2009–2016) in order to get insight into the epidemiological scenario of brucellosis in Portugal. A total of 2313 biological samples from patients with clinical suspicion of brucellosis were subjected to immunological techniques for laboratory diagnosis. From 2010 to 2015, a subset of 259 samples was subjected to molecular methods. According to the available data, 167 out of 2313 (7.2%) samples had positive serology for Brucella spp. and 43 out of 259 samples (16.6%) were positive for B. melitensis by real time PCR, being classified as biovar 1 and 3. This study draws attention to the importance of integrating clinical and laboratory data of human cases in order to increase the efficacy of the response measures in case of outbreaks.

Abstract
AIMS We prospectively enrolled 207 patients (121 were 75 or older and 86 younger than 75) who were admitted to three Respiratory Monitoring Units. The primary outcomes were intubation and mortality rates; the secondary outcomes were changes in arterial blood gases analysis, non-invasive ventilation (NIV) duration and length of hospital stay. RESULTS Hospital mortality was similar in the two groups, as were intubation rates. The proportion who died in the very old patient group was 19.8% (24/121) vs. 10.4% (9/86) in the younger group. Intubation rate was 10.7% (13/121) in the very old patient group and 11.6% (10/86) in the younger group. The presence of comorbidities, the severity of illness (SAPS II), the level of consciousness, NIV failure (intubation), absolute value of pH prior to NIV, as well as the changes in pH and paCO2 and PaO2 /FiO2 after 2 h of NIV, were the variables associated with higher mortality. Very old patients had significantly higher NIV duration than younger patients (69.0 ± 47.0 vs. 57.0 ± 27.0 h) (p ≤ 0.03) and hospital stays (11.6 ± 3.8 vs. 8.4 ± 1.4) (p ≤ 0.02). CONCLUSIONS The use of NIV in very old patients was effective in many cases. Endotracheal intubation after NIV failure was not efficacious in either group.

Abstract
Ulcerative colitis is a chronic inflammatory bowel disorder of unknown etiology. Treatment of flare-ups is based on mesalamine and steroids. Treatment of moderate to severe ulcerative colitis with high-dose heparin and low-molecular-weight heparin was reported. The mechanism was assumed to be a combination of anti-coagulant and anti-inflammatory effects. Low-molecular-weight heparin is better and safer than unfractionated heparin. Studies of low-dose low-molecular-weight heparin in experimental models of inflammation and in inflammatory diseases demonstrated a beneficial effect. Our aim in this study was to evaluate the effect of low-dose, low-molecular-weight heparin in active ulcerative colitis. Twelve patients with flare-ups of colitis were prospectively enrolled. Subcutaneous injections of 5-mg enoxaparin were administered at weekly intervals for 12 weeks. Mesalamine doses remained unchanged. Clinical, laboratory, endoscopic, histologic, and quality-of-life scores were evaluated at the beginning and end of the study. Ten patients completed the study. Mean age was 40.1; the female-male ratio was 7:3. Mean Mayo scores were 9.0 +/- 0.94 at baseline and 3.4 +/- 2.0 at the end of the study (P = 0.0001). Endoscopic scores decreased from 2.2 +/- 0.4 to 1.2 +/- 1.0 (P = 0.049) and in 7 of 10 patients extent of disease shortened. A significant increase in IBDQL scores from 135.7 +/- 37.17 to 179.6 +/- 45.15 points was demonstrated (P = 0.0117). Adverse events were one hospitalization due to abdominal pain, arthralgia (1), transient peripheral edema (1), and elevation of alkaline phosphatase (1). During follow-up, one patient required colectomy and another experienced an exacerbation. In conclusion, low-dose low-molecular-weight heparin once a week, combined with mesalamine, may be an effective therapy for active ulcerative colitis. It may delay or preclude the need for steroid treatment. Controlled studies to evaluate efficacy are needed.

Abstract
Solvatochromic studies on quinoline (Q), 3-cyanoquinoline (CNQ), 3-bromoquinoline (BrQ) and 8-hydroxyquinoline (OHQ) in pure solvents and alcohol-cyclohexane mixtures have been performed. The results are compared with Proton Nuclear Magnetic Resonance, 1H NMR. studies and AMI calculations. Taft and Kamlet's solvatochromic comparison method was used to disclose solvent effects in pure solvents. These studies shows that the hydrogen bond acceptor ability of the Q ring is diminished and its polarity is increased by the presence of the cyano group in CNQ and the bromo group in BrQ. In OHQ, intramolecular hydrogen bonding has been observed. This interaction is weakened by the interaction with protic solvents. The studies in binary mixtures, alcohol-cyclohexane, show solute-solvent interactions, which compete with solvent self-association in the preferential solvation phenomena. Alcohols with strong ability to self-associate have less preference toward solvation of these compounds. The association constants for solute-ethanol systems were determined by 1H NMR. The results show that the solvent hydrogen bond donor ability is the main factor involved in the interaction with these solutes at the aza aromatic site.

Abstract
BACKGROUND Although more than 30 yr ago the minimum alveolar concentration (MAC) of xenon was determined to be 71%, that previous study had technological limitations, and no other studies have confirmed the MAC value of xenon since. The current study was designed to confirm the MAC value of xenon in adult surgical patients using more modern techniques. METHODS Sixty patients were anesthetized with sevoflurane with or without xenon. They were randomly allocated to one of four groups; patients in group 1 received no xenon, whereas those in groups 2, 3, and 4 received end-tidal concentrations of 20, 40, and 60%, respectively (n = 15 each group). Target end-tidal sevoflurane concentrations were chosen using the "up-and-down" method in each group. After steady state sevoflurane and xenon concentrations were maintained for at least 15 min, each patient was monitored for a somatic response at surgical incision. Somatic response was defined as any purposeful bodily movement. The MAC of sevoflurane and its reduction by xenon was evaluated using the multiple independent variable logistic regression model. RESULTS The interaction coefficient of the multiple variable logistic regression was not significantly different from zero (P = 0.143). The MAC of xenon calculated as xenon concentration that would reduce MAC of sevoflurane to 0% was 63.1%. CONCLUSIONS The authors could not determine whether interaction in blocking somatic responses in 50% of patients is additive. The MAC of xenon is in the range of the values that were predicted in a previous study.

Abstract
BACKGROUND Triple therapy with omeprazole, clarithromycin, and tinidazole (OCT) has been found to be highly effective against Helicobacter pylori infection. However, its efficacy as a second line regimen for patients who failed metronidazole-based triple therapy has not been evaluated. AIM The aim of this study was to evaluate the efficacy of low-dose, short-term OCT therapy in an Israeli population, and to compare results obtained in previously treated and untreated patients. METHODS Patients with duodenal or gastric ulcers and chronic antral gastritis with H. pylori infection as assessed by rapid urease test and/or 14C urea breath test (14C-UBT), were studied. All patients received omeprazole 20 mg b.d., clarithromycin 250 mg b.d. and tinidazole 500 mg b.d. for 7 days. Eradication was assessed by 14C-UBT 4 weeks after treatment. RESULTS One hundred and fourty-four patients (M/F = 81/63) were enrolled (mean age 48.1 years, range 12-78). Eradication of H. pylori was significantly different between patients who were initially treated with this regimen (90/94, 96%) and patients who had previously failed to eradicate H. pylori with standard triple therapy (27/50, 54%). Moreover, the eradication rate was significantly decreased in patients with more than one previous failure (9/22, 41%) compared to that in patients with only one failure (18/29, 62%). No other differences such as age, gastric pathology, ethnic origin, smoking habits, or pre-treatment urease activity were found to influence the eradication rate. CONCLUSIONS One-week low-dose triple therapy with OCT is highly effective as an initial therapy in eradicating H. pylori infection. The efficacy is significantly lower when given as a second line treatment in patients who have previously failed to eradicate H. pylori with bismuth-based standard triple therapy.

Abstract
PURPOSE We have used a novel leukocyte adhesiveness/aggregation test (LAAT) to show that many patients with inflammatory bowel disease (IBD) in clinical remission have a subclinical low grade inflammation. METHODS Included in the study are 500 controls, 96 patients with IBD in remission, and 106 patients in relapse. RESULTS The percent of aggregated white blood cells detected in the peripheral blood was 5.9 +/- 3.9, 9.1 +/- 5.9, and 18.8 +/- 9.4, respectively. The difference between each group and any other was significant at P < 0.0001. Similar results were obtained when other acute phase reactants like the erythrocyte sedimentation rate, white blood cell count, differential count, and C-reactive protein level were examined. However, in a linear regression analysis, LAAT was the only significant (P < 0.0006) variable that could classify correctly each subject to the appropriate category of control and IBD in remission or relapse. CONCLUSIONS Identification of patients with IBD in clinical remission who have ongoing inflammation may be of clinical-therapeutic relevance. The LAAT is a simple, rapid, and convenient test. The present study indicates that it is also very sensitive.

Abstract
To date, there are no firm clinical, demographic, biochemical, serologic, or histologic features predicting which patients with chronic hepatitis C are more likely to respond to therapy with interferon-alpha. Serum iron, total iron-binding capacity, transferrin saturation, and ferritin were measured in the fasting state. The amount of stainable iron in liver biopsy specimens was evaluated histochemically as well. All patients received subcutaneous recombinant human IFN-alpha 2a three million units thrice weekly by self-administration. Eleven of 13 (84%) responders had low to normal serum iron levels as compared to one of 26 (4%) nonresponders (P < 0.001). The serum transferrin was similar in both groups, but iron saturation was significantly lower in responders (30 +/- 10%) than in nonresponders (53 +/- 12%) (P< 0.001). Serum ferritin and hepatic iron content were higher in nonresponders (NS). It is suggested that increased serum iron and transferrin saturation blunt the action of interferon, as they have opposite effects on the immune system. Iron overload can thus lead to a poor response to interferon. It remains to be seen whether reducing iron overload will improve the response to interferon therapy.

Abstract
The aim of the study was to determine the comparative usefulness of inflammatory markers, in evaluating disease activity in patients with inflammatory bowel disease. Disease activity was assessed by the Mayo Clinic score for ulcerative colitis, and Harvey-Bradshaw score for Crohn's disease. Five hundred normal blood donors who had no underlying inflammatory condition served as controls. The erythrocyte sedimentation rate, platelet and white blood cell count, C reactive protein, and the leucocyte adhesiveness/aggregation test (LAAT) were determined in each patient. One hundred and twenty four patients with inflammatory bowel disease were tested while in remission and 128 in relapse. Their mean (SD) per cent of aggregated white blood cells in the peripheral blood was 8 (5) and 17 (10) respectively compared with controls 6 (4) (p < 0.0001). Moreover, the LAAT could effectively discriminate between various grades of disease activity, the values in patients with active disease being 13 (6)% in mild, 17 (10)% in moderate, and 26 (10)% in severe disease (p < 0.0001). Other acute phase reactants including the erythrocyte sedimentation rate, the white blood cell count, the platelet count, neutrophil count, as well as, the C reactive protein concentration did not differentiate as well between the various groups. Using logistic regression analysis to differentiate between inflammatory bowel disease patients in remission or relapse, the LAAT was the single best indicator. The addition of any other test did not contribute to the discrimination. Among the different laboratory variables tested only the LAAT significantly discriminated between the five different subgroups of controls, remission and mild, moderate or severe disease activity.

Abstract
This study tested the influence of pretreatment bacterial density on the eradication rate of Helicobacter pylori with triple therapy. One hundred and thirty two patients with endoscopically confirmed H pylori positive, duodenal ulcer or antral gastritis were treated with triple therapy (colloidal bismuth/metronidazole/amoxicillin) for two weeks. Pretreatment urease activity was assessed by the 14C-urea breath test (UBT) in all patients. The mean (SD) pretreatment UBT concentration was similar in patients with duodenal ulcers (318.4 (175.0)) and patients with antral gastritis (288.9 (165.5)). Overall eradication of H pylori was achieved in 85 of 132 patients (64.4%), but was significantly different between patients with high, intermediate, or low pretreatment urease activity (37.5%, 69.5%, and 87.8% respectively). The mean post-treatment UBT value of patients in whom eradication failed was in direct correlation with the pretreatment UBT values. In conclusion, bacterial density, as assessed by urease activity, is an important factor in predicting H pylori eradication. It is suggested that the pretreatment UBT has the potential to identify patients who require modification of the standard therapeutic regimen.

Abstract
During a 29 month period, 46 patients with chronic hepatitis C virus (HCV) received recombinant human interferon alpha-2a for 6 months and were followed for another 6 months. The dose of interferon was three million units thrice weekly and was increased to six million units if amino transferase levels failed to return to normal after 2 months of therapy. At the end of the treatment 19 patients had a complete response, 6 had a near complete response, 2 patients had breakthrough during treatment, and the remaining 19 did not respond at all. Six months after treatment only 10 of the 19 responders remained in remission. Post-transfusion disease was associated with a significantly higher remission rate than sporadic disease (9/22 vs. 1/24, P < 0.001), as was also found in non-cirrhotic compared to cirrhotic patients (9/27 vs. 1/19, P < 0.001). Age, sex, duration of disease, serum aminotransferase, albumin, bilirubin, alkaline phosphatase, or Child's classification did not correlate with treatment response. Severe side effects necessitating cessation of treatment occurred in six patients, four of whom had major autoimmune phenomena. We conclude that careful selection of HCV patients with favorable response characteristics (post-transfusion etiology and non-cirrhotic liver) and without autoimmune manifestations can improve the remission rate and decrease the complication rate during interferon treatment.

Abstract
One hundred twenty-three patients with chronic liver diseases of various etiologies were evaluated for their iron status. The patients were divided into four distinct groups: chronic hepatitis C (63), chronic hepatitis B (14), B + C (3) and nonviral chronic liver diseases (43). In 107 patients (87%) the chronic liver disease was confirmed by biopsy. Mean serum iron (+/- SD) levels in the above four groups were: 166 +/- 62, 103 +/- 52, 142 +/- 48, and 115 micrograms/dl; iron-binding capacity was 346 +/- 80, 325 +/- 72, 297 +/- 27, and 374 +/- 75 micrograms/dl, and iron saturation 50 +/- 18, 32 +/- 16, 48 +/- 16, and 28 +/- 10%, respectively. Serum ferritin, increased in all four groups, was highest in HCV; however, no evidence of hepatic iron accumulation could be found in any of the patients. There were no significant differences in liver function parameters measured in the four groups. We conclude that serum iron, iron saturation, and ferritin are increased in patients with hepatitis C in comparison to hepatitis B or other nonviral, nonhemochromatotic liver diseases. The increased iron status in hepatitis C patients is not manifested by increased liver iron. Awareness of these distinct features of chronic hepatitis C is essential in the diagnosis and treatment of chronic liver diseases.

Abstract
OBJECTIVES The seasonal variation of duodenal ulcer disease and its complications have been repeatedly demonstrated in Israel by several independent studies. The aim of this study was to determine possible seasonal variations in the occurrence of H. pylori infection among dyspeptic patients in Israel. METHODS All 14C-urea breath tests performed in dyspeptic patients at the gastroenterology department in the Tel Aviv Medical Center from January 1991 to December 1992 were reviewed. The monthly variation in the proportion of patients with H. pylori infection was determined, and compared with that of an unrelated 14C-cholyl-glycine breath test. RESULTS Altogether, 702 patients were examined, and 371 (52.8%) of them were found to be infected with H. pylori. During summer months (July-September), a significant decrease in the percentage of patients infected with H. pylori was found, compared with winter months (December-January, 42.3% vs. 60.9%, p < 0.007). No seasonal variation was found in the results of 14C-cholyl-glycine test. The fluctuations in H. pylori infection were highly correlated with the seasonal occurrence of peptic ulcer disease in Israel. CONCLUSIONS The frequency of H. pylori infection in dyspeptic patients in Israel is significantly increased during the winter months and decreased in the summer. This seasonal variation is identical to that found in duodenal ulcer disease. Thus, the seasonal variation of peptic ulcer disease could be explained by H. pylori infection, as seen in other communicable infectious diseases.

Abstract
An ileitis developing years or months after ileostomy was recognised and described many years ago but has rarely been mentioned since. We describe nine patients with a non-specific preanastomotic ileitis that developed years after colectomy in patients operated on for ulcerative colitis or carcinoma. The disease developed after various types of reconstruction: ileorectal, ileoanal, with or without pouch. The diseased ileum showed inflammation, erosions, ulcerations, and sometimes strictures. The disease course ranged from asymptomatic to severe pain and diarrhoea. No specific cause could be shown. Granulomas, infectious agents or ischaemic changes were not found. The anastomosis was always patent. Three patients have had numerous episodes of intestinal obstruction presumably because of adhesions. Seven of nine patients were female. The response to steroids, 5-aminosalicylic acid preparations, and methotrexate was poor, three patients responded well to azathioprine. The condition is not rare and the cause remains unknown.

Abstract
Helicobacter pylori (HP) is considered the etiological agent of chronic active gastritis and suspicion is strong that it plays an important role in duodenal ulcer. Recently, several clinical studies reported that eradication of HP markedly reduces the frequency of ulcer relapse. Triple-drug treatment, including a bismuth salt and 2 antibiotics (usually metronidazole with either amoxycillin or tetracycline) is considered the treatment of choice. It has been shown that the most important factor for predicting success of treatment is the sensitivity of HP to metronidazole, which varies considerably. In the present study we evaluated antimicrobial susceptibility of 18 HP clinical isolates, as well as effectiveness of triple therapy for eradicating HP infections in 65 patients. In vitro, HP was highly sensitive to amoxycillin, erythromycin and tetracycline (100%), and also to metronidazole and tinidazole (94%). Sensitivity to chloramphenicol was low (50%). In our clinical study, the overall eradication rate was 66%; it was higher among women (80%) than men (54%), probably due to better compliance. It is concluded that HP strains in Israel are highly sensitive to metronidazole and that triple therapy is effective, providing compliance is good.

Abstract
The transformation of xenobiotics and endogenous compounds to active carcinogens and their subsequent deactivation as an aid to eradication may be important in the etiology of some gastrointestinal cancers. In mammals the gastrointestinal tract has been shown to be an important site of inducible enzyme systems active in mucosal biotransformation, but few data are available in man. The mucosal activity of CYPIA1 (formerly aryl hydrocarbon hydroxylase), a potential carcinogen-activating enzyme, and catechol-O-methyl transferase, a potential carcinogen-inactivating enzyme were determined in colonic tissue obtained by biopsy. There were no significant differences in activity rates in normal mucosa between colorectal cancer and healthy persons, but significant differences are seen in patients with a history of neoplasia with no evidence of recurrence. The levels of activity of these carcinogen-inductive and -protective enzymes may be prognostic markers, in that the balance or imbalance could play a role in the recurrence of neoplasia. This will require confirmation and prospective studies.

Abstract
An agar dilution assay was used to assess the effect of inoculum size and culture period on the susceptibility of 15 clinical isolates of Helicobacter pylori to ampicillin, erythromycin, tetracycline, chloramphenicol, metronidazole and tinidazole. The mean MIC of the isolates increased 2.2- to 21.2-fold as the inoculum size progressed from 10(3) to 10(7) cfu/spot. Identical results were noted when isolates were maintained for two or four days prior to testing. Inoculum size should be carefully controlled when assessing the in vitro susceptibility of Helicobacter pylori.

Abstract
A case-control study of Japanese women in Nagoya was conducted to investigate the significance of passive smoking and other factors in relation to the etiology of female lung cancer. A total of 90 nonsmoking patients with primary lung cancer and their age- and hospital-matched female controls were asked to fill in a questionnaire in the hospital. Elevated relative risk (RR) of lung cancer was observed for passive smoking from mother (RR = 4.0; p less than 0.05) and from husband's father (RR = 3.2; p less than 0.05). No association was observed between the risk of lung cancer and smoking of husband or passive smoke exposure at work. Occupational exposure to iron or other metals also showed high risk (RR = 4.8; p less than 0.05). No appreciable differences in food intakes were observed between cases and controls.

Abstract
Hyperglucagonemia accompanies several disorders such as acute pancreatitis and diabetic ketoacidosis characterized by increased amylase/creatinine clearance ratio (ACCR). We tested the hypothesis that glucagon may be responsible for the augmental ACCR among diabetic and/or obese subjects. A constant glucagon infusion (15 ng/kg/min) was given to eight noninsulin-dependent diabetics and to eight obese subjects to attain glucagon levels comparable with those obtained during acute pancreatitis. The ACCR significantly increased from 0.9 +/- 0.1 to 1.5 +/- 0.1% (p less than 0.005) in both noninsulin-dependent diabetics and obese subjects, whereas among normal control subjects the ACCR increased from 0.84 +/- 0.8 to 1.3 +/- 0.14% (p less than 0.001). Because the increased values observed in either noninsulin-dependent diabetics or obese subjects are less than the ACCR values observed in acute pancreatitis or in diabetic ketoacidosis, the elevated ACCR in those conditions is only partially explained by the hyperglucagonemia.

A 37 year old man with Behçet's disease who was maintained on prolonged corticosteroid therapy, developed diabetic ketoacidosis and pneumonia. Secondary infection with mucor intervened with abscess formation cured by pneumonectomy. The association of Behçet's disease and mucormycosis has not been previously reported, although diabetes mellitus was almost certainly the predisposing cause. Surgical treatment offers the best chance of survival in similar cases.

Abstract
Prophylactic platelet administration is indicated at counts below 20 X 10(9)/l. The bleeding tendency and severity were compared between thrombocytopenic patients with acute-lymphocytic leukemia (ALL) and acute non-lymphocytic leukemia (ANLL) in the ranges of 10-20 X 10(9)/l platelets, while prophylactic platelet administration was given only below 10 X 10(9)/l. The bleeding tendency for ALL was quite similar at platelet counts above or below 10 X 10(9)/l. The bleeding tendency was significantly lower (p less than 0.001) when the platelets were above this level in ANLL patients. When the thrombocytopenia was caused by chemotherapy, the bleeding was significantly lower in both types of leukemia above 10 X 10(9)/l (p less than 0.05 for ALL, p less than 0.001 for ANLL) as compared with lower counts. When the thrombocytopenia was caused by leukemia, the bleeding tendency was similar in both types of leukemia and at all platelet counts (below 20 X 10(9)/l). Fever, not associated with sepsis, augmented the bleeding severity of patients with ANLL. Stable or rising counts of platelets were associated with significantly lower bleeding tendency above 10 X 10(9)/l only in ANLL patients. The decision for prophylactic platelet administration at counts below 20 X 10(9)/l should be guided by the type of the leukemia (ALL vs. ANLL), the cause of thrombocytopenia (chemotherapy vs. leukemia per se), the trend of the platelet counts, presence of fever and patient's age (below or above 18 years).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The possibility that fever may be an early manifestation of colorectal carcinoma was examined. Of 92 consecutive patients, 28 had preoperative fever. In four patients the fever was the presenting symptom of the colonic tumor, and in another six patients it preceded gastrointestinal complaints by 1 week to 4 months. Fever was thus the earliest manifestation of colorectal carcinoma in 10.8% of the patients. In 13 of the 28 patients the fever could not be explained by the intraoperative findings. We suggest that transient bacteremia may be a common but frequently overlooked manifestation of colonic cancer. Prognosis of the patient may be improved by alertness to the possibility that an episode of unexplained fever may be the first, and sometimes the only, manifestation of colorectal carcinoma.

Abstract
A 25 year old woman suffering from recurrent attacks of hypoglycaemia underwent a laparotomy for suspected insulinoma. No tumour was found, but histology showed islet cell hyperplasia and nesidioblastosis. Although these changes have been reported as a cause of hypoglycaemia in infants, they are only rarely the cause of hypoglycaemia in adults; in the present case they were found to be the result of covert sulphonylurea administration. The fact that sulphonylureas can cause nesidioblastosis is not well recognised by either physicians or pathologists and it should be considered before "cryptogenic nesidioblastosis" is deemed the cause of hypoglycaemia in adults.

Abstract
A 32-year-old woman with histiocytic lymphoma was in complete clinical remission after two courses of chemotherapy, when peripheral neuropathy developed fulminantly. Abnormalities included facial nerve paralysis, dysphagia, quadriparesis, myalgia, and incontinence. She died 10 days after onset of these symptoms. Postmortem examination revealed infiltration of peripheral nerves by lymphomatous cells with no involvement of meninges, brain, lymph nodes, or other organs. Differences in the blood-brain barrier of peripheral and central nervous system are suggested: The peripheral barrier may be more penetrable by malignant histiocytes or less permeable to cytotoxic drugs. Intrathecal chemotherapeutic drug instillation and irradiation may be beneficial.

Abstract
Hyperglucagonemia accompanies several clinical conditions characterized by increased amylase/creatinine clearance. We tested the hypothesis that glucagon may be responsible for this augmented clearance. Therefore, a constant glucagon infusion was given to eight volunteers in order to attain physiological levels comparable to those obtained during acute pancreatitis. The amylase/creatinine clearance increased from 0.84 +/- 0.8% to a mean of 1.30 +/- 1.14% (p less than 0.001). This was, however, less than the clearance of 2.94 +/- 0.23% observed during acute pancreatitis. The rise in amylase clearance during acute pancreatitis is, therefore, only partially explained by the hyperglucagonemia.

Abstract
In a hypothyroid patient who suffered also from chronic obstructive lung disease and mild congestive heart failure, treatment with 1 g/day theophylline administered orally, was followed by a life-threatening theophylline intoxication manifested by repeated epileptic fits and ventricular fibrillation, successfully reverted to sinus rhythm. The plasma theophylline was 34.7 micrograms/ml when the life-threatening arrhythmia occurred. Pharmacokinetic studies conducted during the hypothyroid state revealed a markedly prolonged theophylline plasma half-life of 29.5 h. 2 months later, after reestablishment of an euthyroid state, theophylline plasma half-life was shortened to normal, i.e. 5.7 h and the theophylline plasma level was 13.5 micrograms/ml, while the daily intake was 1 g. We conclude that hypothyroidism may predispose to theophylline intoxication, probably because of the decreased activity of the hepatic microsomal drug-metabolizing enzymes, responsible for the degradation of theophylline.

Abstract
A patient with thrombotic thrombocytopenic purpura was treated with 8 U of fresh frozen plasma, resulting in a rapid improvement in her condition and subsequently followed by a prolonged clinical remission. The transmission and scanning electron microscopic examinations of the platelets performed before treatment demonstrated marked anomalies of the platelet morphology, namely, an increased number of abnormally elongated pseudopods with terminal knobs, a decreased number of platelet granules and excess of glycogen and marked anisocytosis. These anomalies remained unchanged when reexamined 2 months after the achievement of the clinical remission. The question whether these platelet abnormalities are an integral part of thrombotic thrombocytopenic purpura and play a role in its pathogenesis, is raised.

Abstract
A patient with acute myelogenous leukemia developed severe hypophosphatemia manifesting by extreme weakness, confusion, loss of sphincter control, nuchal rigidity, hyperesthesia, hemolysis, congestive heart failure and liver dysfunction. The possible causes for this condition were starvation, parenteral glucose and saline administration, sepsis, hypokalemia and treatment with acetazolamide. A dramatic improvement was noted following phosphate administration.
