A patient with a vipoma of the pancreas and persistently elevated blood levels of vasoactive intestinal polypeptide (VIP) had watery diarrhea, hypokalemia, and achlorhydria (WDHA syndrome). In the untreated state, the diarrhea was never profuse. Fecal volumes ranged from 0.16 to 1.24 L/day. Attempts to correct the dehydration by fluid and electrolyte loading resulted in a massive increase in fecal water and electrolyte loss. Prednisone cured the diarrhea and was associated with a decrease in plasma VIP levels. The patient had a marked circulatory disturbance with systemic arterial hypotension and cutaneous vasodilation that caused a subnormal body temperature. Removal of the tumor led to a dramatic change in the patient's circulation. Generalized vasodilation with systemic venous and arterial hypotension gave away to vasoconstriction with severe venous and arterial hypertension. Central venous pressure rose from -4.4 to +4.0 cm H2O and arterial pressure rose from 80/55 to 195/110 mm Hg. These changes might explain the unexpected and sometimes fatal heart failure that has complicated the removal of these tumors from some patients.

Many articles implicate the nasal ganglion in the production of remote symptoms and discuss treatment. Symptoms are primarily spastic, involving both visceral and voluntary muscles including muscle spasm in the neck, shoulder, and low back; asthma, hypertension, intestinal spasm; diarrhea, angina pectoris, uterine spasm; intractable hiccup, and many others. All these symptoms appear to have 2 common denominators. They are mediated by the autonomic nervous system and at least in some instances can be "psychosomatic." The sphenopalatine ganglion (SPG) is a major autonomic ganglion located superficially in the pterygopalatine fossa, with major afferent distribution to the entire nasopharynx and important connections with the trigeminal nerve, facial nerve, internal carotid artery plexus of the sympathetic nervous system and, as shown in the rat, direct connection with the anterior pituitary gland. This paper presents arguments supporting the following hypotheses: 1. The SPG probably has a crucial role in lower animals in declenching the reflex responses known collectively as the rage reaction. 2. The SPG is a major point of entry to the autonomic system exposed to pathologic influences and readily accessible for therapeutic influences and readily accessible for therapeutic intervention. 3. A wide variety of symptoms are produced or maintained by alteration in autonomic system tonus and some of these may be affected by intervention on the SPG. 4. The possible relationship of some symptoms and "psychosomatic" conditions to the autonomic nervous system and the rage reaction must be considered.20

Small-bowel ischaemia is the least familiar cardiovascular complication of the oral contraceptive but is 1 associated with a high mortality rate and much morbidity. Hoyle et al have recently reviewed 21 cases and found that 1/2 the patients had died and 1/2 had required 2 or more operations, resulting in the removal of much of the small bowel. Small-bowel ischaemia occurs in women taking the oral contraceptive as a result of either mesenteric artery or mesenteric vein thrombosis. The dominant presenting symptom in small-bowel ischaemia, found in all patients, is abdominal pain. Some patients had associated nausea and vomiting; others complained of diarrhea. On examination the patient has usually been found to be febrile with generalized abdominal tenderness. Bowel sounds are present unless infarction has occurred. In nearly all cases reported the diagnosis has been made only at laparotomy, when the bowel was usually infarcted. Since many of the patients had had pain for 2 or more weeks, the condition might be reversible if it could be detected earlier. A diagnosis of small-bowel ischaemia should be carefully considered in any woman taking an oral contraceptive who presents with vague abdominal pain and has an associated condition known to predispose to circulatory disorders: cigarette smoking, hyperlipidaemia, diabetes, hypertension, obesity, or blood group A. If it seems like small-bowel ischaemia is the likely diagnosis, the contraceptive pill should be stopped immediately and treatment started with heparin.

Over 625 patients having gastric bypass for the treatment of morbid obesity are currently being followed at the University of Iowa. Many innovations have increased operative exposure, greatly reduced operating time, and improved the effectiveness and safety of the operation. Recent weight figures show that a 55 percent loss of excess weight can be expected. Several comparative studies between gastric and jejunoileal bypass show that gastric bypass, while producing identical weight loss, has few of the many complications such as liver failure, renal and gallstone formation, diarrhea, enteritis, that are commonly associated with jejunoileal bypass. Stomal ulcer occurrence has been only 2 percent. Imporvements in diabetes mellitus and hypertension can be expected with weight loss. Other effects of gastric bypass were determined by use of a questionnaire. It is concluded, by surgeons having experience with both gastric and jejunoileal bypass, that gastric bypass is the treatment of choice for morbid obesity when nonoperative measures fail.

A study of 200 pregnant women at the State Zenana Hospital, Jaipur, was conducted to analyse the effects of various maternal diseases on neonates. The maternal diseases were anemia, hypertension, urinary tract infection, heart disease, and tuberculosis. 200 healthy pregnant women were studied as controls. A high incidence (64.3%) of low birth weight babies were born to the unhealthy mothers. 80% of the tubercular mothered babies weighed less than 2.5 kg; 70% of the heart disease; 65% urinary tract infections; 60% hypertensive; and 64.3% anemia. The abnormal newborns showed a smaller average length and smaller head circumference (less than 33 cm.) than the normal group. There was also higher incidence of prematurity and poor neurological status among the abnormal group. Congenital malformations accounted for 2.15% in the abnormal cases, compared to .5% in the control group. The morbidity rate was 85%, compared to 46% in the controls. The causes were conjunctivitis, diarrhea, and cord sepsis.

Information on adverse health effects of occupational exposures to sodium sulfate dust is lacking. A study was conducted on 119 workers from five sodium sulfate surface solution mines in Saskatchewan. The investigation involved the older workers and the workers at highest dust exposure levels and included general medical screening with emphasis on the existence of hypertension, edema, calcium tetany, anemia, common skin problems, nasal septum perforation, persistent diarrhea; lung function tests; serum analyses for sulfate, calcium, sodium, and chloride content; and urinary inorganic sulfate output. All measured properties, including lung function, serum sulfate, calcium and electrolytes, were found to be within normal ranges. Forty-two workers with more than 10 years exposure experience show no significant differences in these properties compared to 77 workers with less than 10 years exposure experience. No abnormality could be discovered that might be related to such exposure.

Frequently the first clinical sign of neuroblastoma is not caused by local or metastatic tumor growth but is a paraneoplastic symptom (PNS). Such PNS are fever, diarrhea, hypertension, weakness of muscles, Horner's syndrome and myoclonic encephalopathy. Certain PNS disappear with tumor removal, other do not. The clinical importance of PNS is the prognostic and especially diagnostic value. The pathogenetic relations between tumor and PNS as discussed in the literature are interesting but mostly speculative. Effects of Catecholamines and/or immunologic reactions are thought to be the most probable cause of PNS.--The article is based on current literature; in addition, two short case histories are presented.

Effects of a single intravenous dose of highly purified staphylococcal enterotoxin A (SEA; 0.5 mg/kg) were studied in conscious rhesus monkeys. The mean survival time for four of five experimental monkeys was 8.7 h. Vomiting, pallor, abdominal distension, occasional diarrhea and dehydration were observed. Tachycardia and sustained hypotension developed prior to death. During vomiting, transient hypertension was induced.

This is the first published report in Israel of ischemic colitis in a woman using the contraceptive pill; 20 such cases have been reported in other parts of the world. The patient was a 46 year old married woman with 3 children; she had been in good health except for obesity and chronic hypertension. Her medications included an oral contraceptive for a period of 3 years, and methyldopa for treatment of her hypertension. She presented with abdominal pain and diarrhea of 5 weeks duration. She underwent surgical reanastamosis of the bowel and was doing well at follow-up 1 year after surgery. The presence of ischemic colitis was definitively diagnosed by histological examination; the differential diagnosis included cancer, ulcerative colitis, Crohn's disease, and infectious disease. The authors note that although there is possible association between taking oral contraceptives and the appearance of ischemic colitis, there is not yet any statistical evidence for such a relationship. Similar cases have been reported among young women who were not using oral contraceptives.

84 of 89 cases were traced 18 to 27 years after Swenson's operation. Seven had long segments. All were alive and in good general health except one who had renal transplant for hypertension due to pyelonephritis in a residual solitary kidney. 61 are married of whom 34 have children. None of the children have Hirshsprung's disease. 48 were fully normal within one year of operation. 29 had constipation enough to require treatment. Seven had diarrhoea which in three required hospitalisation for electrolyte disturbances and dehydration. 39 had some degree of soiling, but in only nine was this troublesome. Recovery of normal bowel control was more rapid in those with a good social background. Eight had postoperative strictures, but treatment has remained successful in the long-term in seven of these. Five patients had inadequate resections and are well after further surgery. Nine had urinary incontinence of which seven had only nocturnal enuresis. All are fully recovered. Two male patients have absence of ejaculation and two females are infertile with scarred Fallopian tubes. 83 of the 84 now have normal bowel control and good health. One has a permanent ileostomy.
