Hepatic function following portoenterostomy for extrahepatic biliary atresia.

Liver structure and function in 10 patients with extrahepatic biliary atresia were studied after portoenteric anastomosis (Kasai operation). Bile flow adequate to reduce the serum bilirubin concentration was established in five patients (improved group), three of whom became anicteric. The serum bilirubin concentration did not decrease in the remaining five patients (unimproved group). Hepatic effluent collected postoperatively from both groups contained small amounts of cholesterol and bilirubin; bile salts, however, were present in the hepatic effluent of only the improved patients. Liver biopsy specimens obtained postoperatively from the five improved patients showed partial (in two) or complete (in three) relief of cholestasis; hepatic fibrosis, however, was unchanged (in one) or worse (in four). The serum concentrations of bile salts were markedly elevated, despite normal excretion of sodium sulfobromophthalein and rose bengal, in two anicteric patients studied 14 and 24 months postoperatively. It is concluded that neither structure nor function of the liver is normalized by portoenterostomy even in clinically well, anicteric patients.     

Prognosis for the patients with chronic hepatitis B

The purpose of the research was to determine the influence of the hepatitis B virus on the progression of the chronic liver disease. In the present paper, 127 patients who were followed up for five years and who had histologically verified chronic liver disease, are described. Fifty two of them were carriers of HBsAg, 75 patients were HBsAg negative, but had other markers typical for a previous infection of HBV in the sera. All the patients were nonalcoholics and no drug addicts. In the sera of these 127 patients markers of HBV were prospectively followed up: HBsAg, HBeAg, anti-HBs, anti-HBc, anti-HBe, HBVDNA, antiHCV for C virus and anti-D for D virus. It was proved by these investigations that HBV provokes very severe chronic hepatitis: CAH (chronic active hepatitis) and CH (cirrhosis hepatis). It was also proved that HBV replicated in 44.20% patients, namely, HBVDNA was positive in the sera of those patients. In 26.08% of such patients the mutant form of HBV was present. In spite of progressive liver disease and without any antiviral therapy all the patients with chronic HBV cirrhosis hepatis were, after five year-follow-up, in Child-Pugh A grade. It was found that the patients who were HBsAg negative, but had one or more markers of HBV positive in the sera, had also a severe chronic hepatitis. That group of patients remains our object of further research. The five-years follow-up of all these patients demonstrates that it is necessary to find out an efficient medicament against HBV chronic hepatitis. Obligatory vaccination of the risk population against virus B remains the only prevention against this severe disease.     

Fecal Chymotrypsin and Trypsin Determinations

Trypsin and chymotrypsin concentrations were determined in 180 spot stool specimens from 110 control patients in hospital. The lower limit of normality for each enzyme was placed at the 5% level: 95% of this population excreted feces containing more than 100 μg. of chymotrypsin and 30 μg. of trypsin per g. of feces. Chymotrypsin concentrations appeared to be a more reliable guide to pancreatic function than trypsin concentrations.Fecal chymotrypsin concentrations were subnormal in five patients with chronic pancreatitis, borderline in one patient with relapsing pancreatitis, subnormal in one patient after pancreatectomy, and subnormal in five of nine with carcinoma of the pancreas. Subnormal concentrations of fecal chymotrypsin were found in seven of 21 patients with chronic liver disease related to alcoholism, eight of 32 with a partial gastrectomy, three of 10 with adult celiac disease and five of 16 with psoriasis.It appears that the determination of fecal chymotrypsin concentrations provides a valuable screening test for pancreatic exocrine deficiency. However, normal results may be found in some patients with pancreatic disease and subnormal values may occur in some patients with other conditions.     

The Use of Hypnosis in the Treatment of Exhibitionism

The use of hypnosis in the treatment of exhibitionism is described in three patients in whom the condition had been present for more than five years. In each patient there was no subsequent recurrence of the exhibitionism once therapeutic suggestions had been made in a deep hypnotic trance, the follow-up period being respectively five years, four and a half years, and one year.The method of treatment and the results are discussed in terms of the concepts of behaviour therapy.It is concluded that with certain patients suffering from exhibitionism the use of hypnosis may well be one of the best methods of treatment, but considerable care should be exercised to exclude those patients with an underlying psychosis, mental defect or psychopathic condition. It is also noted that the efficacy of the treatment would appear to depend on achieving a satisfactory depth of hypnotic trance. If this is not reached, the results are less likely to be successful.     

Thyrotoxicosis in the African: Clinical and Immunological Observations

The clinical manifestations of thyrotoxicosis are described in 20 African patients with toxic diffuse goitre (Graves''s disease) and five with toxic nodular goitre. Antibody to thyroglubulin was detected in the serum of one patient and antibody to thyroid microsomes in four patients. Round-cell infiltration of the thyroid gland was present in 27% of 30 African thyrotoxic patients and 73% of appropriately matched Caucasian patients. It is suggested that the low incidence of thyrotoxicosis in the African race is related to an inability to form thyroid autoantibodies.     

Weak Ankles. A Study of Common Peroneal Entrapment Neuropathy

Twenty-three patients were seen with entrapment neuropathy in a two-and-a-half-year period. Symptoms consisted of pain, paresis, and paraesthesia in the distribution of the common peroneal nerve. Some degree of paresis was often present, which in five patients was severe enough to cause drop foot. In 20 patients decompression of the entrapped nerve at the neck of the fibula was quickly and completely successful. It is suggested that the ankle weakness which frequently follows sprains and other forced inversion injuries may often be at least partially due to entrapment of the common peroneal nerve.     

Contemporary Themes: Sociomedical Study of Patients over 75 in General Practice

In a survey of people of 75 years and over in a general practice situated in the north-west of England a total of 297 patients was examined. Among the many previously unreported medical conditions and social needs were seven unknown malignant conditions, 28 patients with heart failure, five with diabetes, and one with myxoedema. A high incidence of nutritional anaemia was also found. It is concluded that such a survey can detect much hidden illness and disability and that general practice is the right setting for it.     

Abdominal Bruit after Renal Transplantation

Forty-seven recipients of renal allografts have been studied at varying intervals of up to five years after transplantation. Renal artery bruit occurred in eight of 16 patients observed over the first two post-transplant months and disappeared spontaneously in four of these. The disappearance of the bruit was associated with poor renal function. Renal bruits were audible in 10 patients examined more than two months after transplantation; nine of these were hypertensive and of six in whom arteriography was performed five were shown to have stenosis of the allograft artery. By contrast only eight of 37 patients without abdominal bruit were hypertensive, and arteriography in 10 normotensive patients without bruit showed no stenosis. It is concluded that while a renal artery bruit during the first two months after transplantation may be a marker of good renal blood flow at the time, its presence suggests a poor long-term prognosis since persistence of the murmur indicates that significant stenosis of the allograft artery is likely, while its disappearance is associated with poor renal function.     

Severe Depressive Mood Changes Following Slow-release Intramuscular Fluphenazine Injection

Sixteen patients in whom schizophrenia was initially diagnosed and who were treated with fluphenazine enanthate or decanoate developed severe depression for a short period after the injection. In five cases this depression is thought to have been responsible for suicide. In 8 out of 10 cases the depression responded to electroplexy (E.C.T.). It is recommended that patients who are treated with fluphenazine should be carefully supervised.     

Role of CD23 in astrocytes inflammatory reaction during HIV-1 related encephalitis

Soluble factors released by intra-cerebral activated cells are implicated in neuronal alterations during central nervous system inflammatory diseases. In this study, the role of the CD23 pathway in astrocyte activation and its participation in human immunodeficiency virus-1 (HIV-1)-induced neuropathology were evaluated. In human primary astrocytes, CD23 protein membrane expression was dose-dependently upregulated by gp120. It was also upregulated by gamma-interferon (gamma-IFN) and modulated by interleukin-1-beta (IL-1beta) whereas microglial cells in these stimulation conditions did not express CD23. Cell surface stimulation of CD23 expressed by astrocytes induced production of nitric oxide (NO) and IL-1beta which was inhibited by a specific inducible NO-synthase (iNOS) inhibitor (aminoguanidine), indicating the implication of this receptor in the astrocyte inflammatory reaction. On brain tissues from five out of five patients with HIV-1-related encephalitis, CD23 was expressed by astrocytes and by some microglial cells, whereas it was not detectable on brain tissue from five of five HIV-1-infected patients without central nervous system (CNS) disease or from two of two control subjects. In addition, CD23 antigen was co-localized with iNOS and nitrotyrosine on brain tissue from patients with HIV1-related encephalitis, suggesting that CD23 participates in iNOS activation of astrocytes in vivo. In conclusion, CD23 ligation is an alternative pathway in the induction of inflammatory product synthesis by astrocytes and participates in CNS inflammation.     

Immunological Abnormalities and Hydantoins

Various immunological features were measured in 20 patients with epilepsy who had received prolonged treatment with hydantoins. Immunoglobulin A (IgA) was shown to be absent or low in five patients, β₁C/A was low in 10 patients. Five patients showed negative reactions to skin tests, and two could not be sensitized to dinitrochlorobenzene. The corresponding features were normal in 14 control patients with epilepsy but without hydantoins. It is suggested that the hydantoins influence humoral immunity, whereas other immunosuppressant agents have been found to affect cellular immunity.     

Urinary cytology in renal transplant recipients with stable graft functions

The utility of routine urinary cytology in renal transplant recipients was investigated. Slides of 79 urine samples obtained from 59 renal transplant patients shortly after transplantation and of 275 urine sediments from 126 patients who had received a transplant before 1978 were screened for abnormal urothelial cells. None of the samples taken within one year of transplantation contained malignant cells. For five patients transplanted before 1978, repeated cytologic examinations showed malignant cells, but neither urologic examination nor clinical nor postmortem follow-up studies revealed a tumor. In all five cases, the abnormal cells disappeared from repeat samples within two to three months. None of the other 121 patients, with repeatedly normal urinary cytologies, exhibited a urinary tract carcinoma in the 24-month follow-up period. It would appear that the cytologic findings in the urine of renal transplant patients who have received long-term immunosuppressive medication may be transiently abnormal.     

Skin Homografts in Patients with Cancer of the Cervix

Skin homografts were applied to patients with cervical cancer. In 9% (10 of 110) of untreated patients, grafts survived for more than two weeks. The frequency of prolonged graft survival was increased by pelvic surgery or radiotherapy. It was highest, 62% (34 of 55), in those with recurrent cancer. Recurrence and death in patients studied prior to treatment and followed up six months to two and a half years was three times more frequent in those with grafts tolerated over two weeks than in those rejecting them in a shorter period, i.e. five of 10 and 10 of 74, respectively.     

Secondary amyloidosis and cystic fibrosis. A morphological and histochemical study of five cases

The pathological findings of five cases of amyloidosis associated with Cystic Fibrosis are reported. Rectal biopsy led to the diagnosis of amyloidosis in four patients. In three cases the diagnosis was confirmed at autopsy, with involvement of spleen, liver, kidneys, adrenal glands, thyroid and other organs. It seems that Secondary Amyloidosis provokes a significant, although rare, complication of Cystic Fibrosis as greater numbers of these patients survive into adulthood.     

Advanced Heart Block During Acute Myocardial Infarction Treated with an Electrode Pacing Catheter

The mortality rate is high from advanced atrioventricular block associated with acute myocardial infarction. There is reason to believe that if in these patients the hearts are electrically paced with an endocardial pacing catheter, the mortality rate can be considerably decreased. Five patients in second- and third-degree heart block associated with acute myocardial infarction were paced with a considerable lowering of the expected mortality rate. Twenty-three cases from the literature are also presented and discussed. A silastic bipolar electrode catheter was used in these five cases. Four of the five cases returned to normal sinus rhythm within the first 10 days. The average duration of pacing was 6.7 days. It is the opinion of the author that second- and third-degree heart block associated with acute myocardial infarction should have a pacing catheter introduced at the earliest possible moment for continuous or demand endocardial pacing.     

BOOK REVIEWS

Accidental hypothermia was studied in 11 patients, five of whom died. This condition occurs spontaneously, usually in a cold environment, and should be suspected in the comatose hypotensive patient. It is easily missed because regular clinical thermometers do not record extremely low body temperatures. It is distinguished from other forms of hypothermia by the very low body temperature and by the absence of recognized causes of hypothermia. Ten of the 11 patients were either alcoholic or diabetic. Intravascular thrombosis was the most common complication leading to death.     

Phyllodes tumour: cytologic and histologic presentation of 22 cases, and immunohistochemical demonstration of p53

A retrospective study of 22 cases of phyllodes tumour (PT) was undertaken to evaluate the potential value of fine needle aspiration (FNA) cytology in the diagnosis of benign and borderline PT. Histological material was available from 12 patients with typical benign PT (group 1), six patients with less typical changes (group 2) and four cases of borderline PT (group 3). Cytological presentation of PT in these cases was similar to that described by other cytologists, although abundant cellular material was obtained in only eight FNAs, naked nuclei were present in nine cases only, and atypical or suspicious cytological features were found in seven cases. Comparative analysis of p53 was made in nine patients with PT, five cases with other benign breast lesions and five with malignant lesions. p53 reaction was positive in five of nine patients with PT (all cases from groups 2 and 3), compared with two of five cases of carcinoma. p53 was negative in all patients with PT from group 1 and the five other benign cases. We suggest that cytopathologists should be careful when a myxoid stromal component is present in cytological smears.     

Drugs of Dependence Though Not of Abuse: Fenfluramine and Imipramine

Measures of subjective feeling used by five patients indicated that depression of mood occurred about four days after fenfluramine withdrawal. An experiment in which another 11 patients took fenfluramine 80 mg for 28 days confirmed the depression, maximal on the fourth withdrawal day. It also indicated that in the first week of administration there was some mood elevation, but with feelings of impaired ability to concentrate. The drug reduced appetite and weight. A comparison is drawn with imipramine, which was found to induce initial and withdrawal changes of subjective experience (of dreaming) in six volunteers. It is suggested that certain mood-influencing drugs may not be drugs of abuse because of some unpleasant initial effects, though they can be drugs of dependence.     

Lymphocyte transformation studies in drug hypersensitivity

In a group of patients with clinically diagnosed drug hypersensitivity the in vitro lymphocyte response to the suspected drug was assessed by the lymphocyte transformation test. The test gave positive results in all 15 patients with penicillin-induced immediate or accelerated allergic reactions and positive immediate skin-test reactivity to the major or the minor antigenic determinant of penicillin, or both, but in only 3 of the 12 patients with delayed-onset maculopapular rashes induced by penicillin, despite positive immediate reactivity to the skin-test reagents.Lymphocyte stimulation greater than five times the control level was demonstrated for five patients with penicillin-induced erythroderma, Stevens-Johnson syndrome or a serum-sickness-like illness, or with methicillin-induced interstitial nephritis, all of whom had negative reactions to the appropriate skin-test reagents. A low level of stimulation was seen in eight other skin-test-negative patients with possible allergic reactions induced by penicillins. However, in all subjects tested the stimulation was significantly greater than the mean for control subjects.For 9 of 11 patients with isoniazid-induced hepatitis or maculopapular rashes, but for only 8 of 31 patients with eruptions induced by a variety of drugs other than penicillins and isoniazid, significant stimulation occurred in the lymphocyte transformation test.It is concluded that the lymphocyte transformation test is useful in the detection of hypersensitivity to the penicillins (although in IgE-mediated reactions skin testing is clearly preferable) and isoniazid but is of limited value in the demonstration of hypersensitivity to other drugs.
