Studies were undertaken in 40 patients with chronic pancreatitis six months to seven and a half years (mean 25 months) after operation, results being compared with pre-operative findings. Measurements included: exercise capacity, absence of pain, body weight, endocrine (36) and exocrine (25) pancreatic function. Almost all patients returned to full or only slightly impaired activity, were free of pain or had less pain and weight increase. Exocrine pancreatic function (secretin-pancreozymin test and faecal fat) was noted in 11 of 25 patients. In another 11 pre-operative progression was arrested. But endocrine function improved in only three of 36 and worsened in 13 (manifestation of subclinical diabetes in eight, worse glucose tolerance in five). The results justify a more active surgical approach in the treatment of chronic pancreatitis in order to save the patients from an often long and painful "burning out" of the disease on purely conservative treatment. Furthermore, exocrine pancreatic function, at least, is maintained or improved.

The absorption and excretion of a new doxycycline solution for intravenous use (DOTC iv) were studied with the following results. 1. Serum levels following one shot intravenous injection of DOTC iv in glucose solution showed a good dose-response comparable with that of the same dose injection of pyrrolidinomethyltetracycline (PRM-TC). The urinary excretion was also examined. In 200 mg injection, nausea, general warm feeling, odor in mouth and tongue numbness were complained. 2. When DOTC iv was injected intramuscularly, the serum level did not reach the peak value and low level continued for a long time. Moderate local pain was complained at the site of injection. 3. The serum level following drip infection of DOTC dry fill showed a dose-response as well. The local vein tolerated well. 4. No abnormalities were found in clinical and laboratory examinations in all volunteers.

In patients with stable coronary artery disease, a GIK solution may increase arterial glucose and the arterial-coronary sinus difference of glucose across the myocardium. In the same patients, GIK may reduce arterial free fatty acids as well as the arterial-coronary sinus difference of free fatty acids across the myocardium. As the arterial values of free fatty acids fall, so does the arterial-coronary sinus difference of free fatty acid across the myocardium, defining a myocardial threshold for free fatty acids of approximately 200 mEq/L. Glucose-insulin-potassium may lower free fatty acid values to near or below myocardial threshold in patients with acute myocardial infarction despite recurrent pain. Preliminary data suggest that GIK in the concentration and infusion rates used in this study may favorably influence survival in patients with acute myocardial infarction.

A dilute solution of procaine in glucose solution was injected by slow drip into the lumbar theca of patients to cause a differential block. Vasodilatation of the skin vessels of the lower limbs always occurred before any change in sensibility. The first changes in sensibility were inability to fell painful stimuli and warm stimuli; these two forms of sensibility were usually coextensive and occurred at the same time. When this was not so, either form of sensibility could be more extensively disturbed than the other. When warmth sensibility was removed, cold sensibility was either normal or diminished or cold stimuli caused non-thermal sensations such as non-thermal wetness or pressure. It is concluded that the nerve fibres signalling warmth are the smaller delta fibres or non-myelinated fibres or both. As two groups of investigators who recorded from the non-myelinated fibres in man found no non-myelinated fibres responding to cold, it is condluded that fibres signalling cold cover the same delta range as those signalling warmth, together with a proportion of larger delta fibres. When fibres subserving pain, warmth, and cold were blocked, tactile sensibility could be normal. It is concluded that, if there are tactile fibres in man in the smaller delta and non-myelinated ranges, their contribution to tactile sensibility is insignificant. It is also concluded that the pre-galglionic B fibres are the most susceptible of all fibres of the nerve roots to local anaesthetic agents. On two occasions, piloerection occurred when the pre-ganglionic sympathetic fibres were blocked. In two patients spontaneous itching occurred when all peripheral nerve fibres were blocked except large tactile fibres.

Eight-four patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) were randomized to receive 100 micrograms of octreotide intravenously immediately prior to ERCP, and 100 micrograms subcutaneously 45 min after the initial dose, or placebo. Amylase, lipase, and glucose were measured and clinical assessment was performed before, and 2 and 24 h after, ERCP. We define clinical pancreatitis as the combination of elevated amylase or lipase with abdominal pain and tenderness. Interim analysis in 84 patients revealed an 11% incidence of clinical pancreatitis in the control group and 35% in the treatment group (p < 0.01). There were no differences in either group with respect to sphincterotomy, gender, age, duration of ERCP, number of cannulations of the pancreatic duct, degree of duct injection, or the volume of contrast injected. Analysis of group differences stratified by sphincterotomy revealed the following: 1) In patients who did not undergo a sphincterotomy, there was a significantly higher rate of pancreatitis in the treatment group [10/17 (59%) versus 1/17 (6%) RR 10.0 (95% CI 1.4-69.8)]. 2) Sphincterotomy reduced the rate of pancreatitis in patients who received octreotide from 10/17 (59% no sphincterotomy), to 3/20 (15% sphincterotomy) (p = 0.01), which equals the rate in patients who received placebo and underwent sphincterotomy [4/25 (16%)]. 3) Although the incidence of pancreatitis was higher in the treatment group, octreotide may reduce the severity of pancreatitis measured by the number of days NPO (Wilcoxon rank sum, p = 0.02), length of stay after ERCP (p = 0.13), the number of days of pain (p = 0.11), and the degree of amylase elevation (p = 0.04). We conclude that: 1) Octreotide appears to increase the incidence of pancreatitis when given prophylactically for diagnostic ERCP. 2) Although pancreatitis was more common in the octreotide group, it was less severe than the placebo group. 3) Sphincterotomy may afford protection against pancreatitis in patients who received octreotide. 4) We cannot recommend the use of prophylactic octreotide during diagnostic or therapeutic ERCP.

Spatial patterns of spinal cord glucose metabolic activity were examined in unanesthetized rats with painful peripheral mononeuropathy produced by sciatic nerve ligation (chronic constrictive injury, CCI). Spinal cord metabolic activity was assessed 10 days after nerve ligation by using the fully quantitative [14C]2-deoxyglucose technique. This technique allows simultaneous examination of both neural activity inferred from local glucose utilization and its spatial distribution in multiple spinal regions previously implicated in nociceptive processing. Rats used in the experiment exhibited thermal hyperalgesia to radiant heat applied to the hind paw ipsilateral to nerve ligation and behaviors indicative of spontaneous pain. Sciatic nerve ligation produced a significant increase in spinal cord metabolic activity in four sampling regions (laminae I-IV, V-VI, VII and VIII-IX) of lumbar segments compared to sham-operated rats. The pattern of altered metabolic activity in CCI rats presented 3 distinct features. (1) The spinal cord grey matter both ipsilateral and contralateral to nerve ligation exhibited substantial increases in metabolic activity compared to sham-operated rats. (2) This increase in metabolic activity was somatotopically specific, i.e., higher metabolic rates were observed on the side ipsilateral to nerve ligation than on the contralateral side, and higher metabolic rates were seen in the medial portion of the ipsilateral spinal cord dorsal horn than in the lateral portion. The peak metabolic activity occurred in laminae V-VI of CCI rats, a region involved in nociceptive processing. (3) The increase in spinal cord metabolic activity of CCI rats extended from lumbar segment L1 to L5 in all 4 sampling regions. The substantial increase in metabolic activity in both the ipsilateral and contralateral spinal cord that occurs over an extensive rostro-caudal area in CCI rats may represent a unique pattern of spinal cord metabolic activity distinct from that observed in rats exposed to acute thermal pain. This pattern of spinal cord neural activity in CCI rats may reflect possible radiation of neuropathic pain. In addition, the procedure of curare-induced paralysis in a separate group of CCI rats did not change the extent and patterns of metabolic activity seen in non-paralyzed CCI rats, reflecting a minimal influence of the afferent feedback from flexor motor reflexes on spinal cord metabolic activity following sciatic nerve ligation. This chronic increase in spinal cord neural activity in the absence of overt peripheral stimulation suggests a spinal cord hyperactive state and may account for behaviors suggestive of spontaneous pain in CCI rats.(ABSTRACT TRUNCATED AT 400 WORDS)

In a rat model of painful peripheral mononeuropathy, this study examined the effects of post-injury treatment with a monosialoganglioside, GM1, on abnormal nociceptive behaviors and spinal cord neural activity resulting from loose ligation of the rat common sciatic nerve (chronic constrictive injury, CCI). Thermal hyperalgesia and spontaneous pain behaviors of CCI rats were assessed by measuring foot-withdrawal latencies to radiant heat and by rating spontaneous hind paw guarding positions, respectively. Neural activity within different regions of the spinal cord was inferred in both CCI and sham-operated rats by employing the [14C]-2-deoxyglucose (2-DG) autoradiographic technique to measure spinal cord glucose metabolism. Intraperitoneal (i.p.) GM1 treatment (10 mg/kg) initiated 1 h or 24 h after injury and once daily for the first 9 post-injury days reduced thermal hyperalgesia of the hind paw ipsilateral to nerve ligation and lowered spontaneous pain behavior rating scores in CCI rats. Sciatic nerve ligation reliably increased basal 2-DG metabolic activity of CCI rats in all four sampled regions (laminae I-IV, V-VI, VII, VIII-IX) of spinal cord lumbar segments (L2-L5) both ipsilateral and contralateral to nerve ligation 10 days after injury. Consistent with the drug's effects on spontaneous pain behaviors, 10 daily GM1 treatments (10 mg/kg, i.p.) initiated 1 h after nerve ligation reduced spinal cord 2-DG metabolic activity in laminae V-VI and VII ipsilateral to nerve ligation and in all four sampled regions contralateral to nerve ligation. This attenuation of the increased spinal cord glucose utilization that occurs in the absence of overt peripheral stimulation may reflect an influence of GM1 on increased neural activity contributing to spontaneous pain. Since gangliosides are thought to protect neurons from excitotoxic effects of excitatory amino acids, these results suggest that ganglioside treatment may result in attenuation of excitatory neurotoxicity that may occur following peripheral nerve injury. Thus, ganglioside treatment could provide a new approach to the clinical management of neuropathic pain syndromes following peripheral nerve injury.

In a prospective clinical-experimental study, 15 patients with chronic pancreatitis operated consecutively due to severe pain were examined for the effects of a duodenum-preserving resection of the pancreas head on endocrine pancreas function. This was done by means of oral and intravenous glucose tolerance testing before the operation, on the 10th or 11th postoperative day, and three months after the operation. In addition to glucose levels in the peripheral venous blood, levels of insulin, C-peptide, glucagon, somatostatin, and pancreatic polypeptide were determined. As indicated by the k-value, glucose tolerance improved postoperatively in 11 patients; two patients showed no change, and one patient was worse. Only one patient developed evident diabetes mellitus immediately postoperatively. The pre- and postoperative levels of insulin and C-peptide showed no significant differences. The fasting levels of glucagon were significantly lower postoperatively than before the operation (2p less than 0.01). Duodenum-preserving pancreas head resection led to improvement of the glucose tolerance in the majority of patients; a deterioration was observed only in two cases.

To evaluate the efficacy and safety of octreotide (a somatostatin analogue) in the treatment of acromegaly, 10 patients were injected subcutaneously with octreotide, 50 micrograms, thrice daily before each meal for two days, followed by 100 micrograms thrice daily for six months. One case dropped out at the initial stage because of diarrhea, and another quit due to a lack of improvement in headaches after treatment for three months. Eight patients completed the study. The results showed that the circumference of the fourth finger and hand volume significantly decreased after treatment. Laboratory data demonstrated that serum growth hormone (GH) and somatomedin-C levels also decreased significantly. However, in six patients without a history of trans-sphenoidal adenomectomy, the serum GH and somatomedin-C levels returned to normal in only one case who had a serum GH level < 20 mU/L before treatment. In the oral glucose tolerance test, paradoxic elevation of GH subsided after treatment. In the TRH test, paradoxic elevation of GH improved after treatment. In the bromocriptine test, octreotide had a synergistic effect on the suppression of GH. All cases had the side effect of injection pain, especially at the initial stage. An increase in intestinal peristalsis and bowel movement occurred in the first week, but symptoms later subsided. Two out of these eight patients had gallbladder sludge after six months of treatment. In conclusion, octreotide is effective in the treatment of acromegaly; however, it is better used in patients who have serum GH levels < 20 mU/L, or after a trans-sphenoidal adenomectomy, and may be combined with bromocriptine to treat the patient.(ABSTRACT TRUNCATED AT 250 WORDS)

Various sites may be used to obtain blood (plasma) for the determination of the glucose concentration in the neonate. Because multiple sites may be sampled in the same neonate, it is important to determine the variability in blood glucose concentration which may result from such sampling. Since pain and mechanical forces may be different because of the method used to obtain the capillary (heelstick) blood compared to the venous specimen, the two sites were sampled, and the blood glucose concentration was determined simultaneously in 25 asymptomatic well neonates whose mean birth weight was 2,562 +/- 152 g and whose gestational age was 35.5 +/- 1.5 weeks. There was a significant (p less than 0.0001), but relatively weak correlation (r2 = 0.64) between capillary (heelstick) blood and venous blood relative to blood glucose concentration. When the capillary (heelstick)-venous glucose concentration difference was compared to the mean of the capillary (heelstick) and venous glucose concentrations, a difference of +/- 0.5 mM (9 mg/dl) was noted in 3 of 25 neonates. Appropriately obtained capillary (heelstick) blood samples provide measurement of blood glucose concentration which are variable compared to venous samples, but which are probably not significant physiologically.
