The expression of six lectins (Arachis hypogaea, B. simplicifolia I, concanavalin A, Dolichus biflorus, Triticum vulgaris, Lotus tetragonolobus) was studied in 24 adenocarcinomas, 24 adenomas, 20 metaplastic polyps, 17 specimens of mucosal prolapse (solitary ulcer syndrome) and 10 of normal mucosa, all taken from the rectum. Qualitative, quantitative and distributive differences in lectin expression were observed between adenocarcinoma and normal mucosa. These cancer-associated glycoprotein alterations were also observed, though to a lesser extent, in benign neoplastic and non-neoplastic lesions of the rectum. It appears therefore that the glycoprotein modifications associated with malignant transformation are not specific indicators of malignancy. It is suggested that the common denominator is a disturbance in the activities of enzymes, particularly the glycosyl-transferases and glycosidases, involved in the biosynthesis of glycoprotein. This disturbance can occur in situations where cells are less differentiated either through developmental immaturity, rapid cellular division or neoplastic de-differentiation. These changes are therefore more likely to reflect the state of differentiation rather than the malignant nature of the cells. It is shown that the greater the deviation of the lesion from normal the greater the glycoprotein alterations. The potential usefulness of lectin expressions as predictive indicators of biological behaviour of adenocarcinomas of the large bowel needs further studies.

The presence of mucosal hyperplasia and sialomucin goblet cell secretion (transitional mucosa) was assessed in various benign, premalignant and malignant colorectal tissues. Transitional mucosa was seen in diverticular disease, solitary ulcer syndrome of the rectum, ischaemic and irradiation colitis and other diseases including pneumatosis coli, endometriosis, haemorrhoids and a colostomy margin. Adenocarcinomas had a sulphomucin or mixed secretion pattern with transitional features in the adjacent mucosa mucosa (18/27). Premalignant adenomatous polyps showed mixed secretion with transitional glands incorporated in the stalk and sometimes in the adjacent mucosa. Epithelium showing dysplasia secreted sulphomucins and in amounts related to its degree of differentiation. Transitional mucosa may not be a primary premalignant phenomemon. The conclusion and unifying concept is that it is a secondary event related to goblet cell immaturity. This can occur, secondary to proliferation in mucosal inflammation, ischaemia and prolapse or as a phenotypic expression of growth derived from underlying dysplastic epithelium.

The article reports on a twin pregnancy with EPH gestosis in a 20-year old primipara which could be prolonged by tocolysis and emergency cerclage after signs of premature delivery and prolapse of the amniotic sac in the 28th/29th pregnancy week. At the beginning of the 30th gestation week there was an unavoidable delivery of the first twin (920 g) who survived for 5 days only due to immaturity and hypotrophy. Directly after delivery of the first twin the pregnancy for the second twin was prolonged by renewed tocolysis and renewed circular suture of the cervix. This enabled the second child, whose growth had been retarded like that of the first one, to continue to grow for some time. Unavoidable delivery of the second twin (1,650 g) eventually occurred at the beginning of the 32nd week of pregnancy. The eutrophic child survived without the slightest complication. This case is presented in detail and discussed, including the histology of the placenta. The most important points for enabling the survival of a twin foetus are sufficient tocolysis, a satisfactory technique for occlusion of the os uteri, as well as exclusion and prevention of chorioamnionitis.

Little is known about the reasons for rupture of the fetal membranes before the onset of labour. When this occurs before term, there is an increase in perinatal mortality principally due to immaturity, less commonly due to infection, and rarely due to asphyxia as a result of cord prolapse. Management consists of delaying delivery until satisfactory levels of surfactant are present in the liquor amnii or until intra-uterine infection intervenes, in which case delivery is expedited. The care of patients with preterm rupture of the membranes should be conducted in a unit equipped with intensive perinatal care facilities.

The oral zone reflects the relational modalities of the child: the sensorimotor physiological and psychological behaviour is established according to the development of the facial sphere and its aero-digestive crossroads. In the baby, the mandibular equilibrium and position and the dimensions of the lower part of the face essentially depend upon praxic activities, which drive the mandibular and hyoid displacements. During the period of immaturity, the lingual area is brought into movement with each "sucking-swallowing" action that characterises breast-feeding: the mandibulo-hyoid swing is subordinate to the pharyngo-lingual complex. The analysis of this psycho-motor behaviour reveals imperfect and upsetting "mimics" that modify the balance of the jaw and of the hyo-lingual area during swallowing, which is the second phase of the reassurance breast-feed. The lingual ptosis causes congestion of the airways. These lax children, with a receding chin, are deformed by their oral habits. The clinical picture evidences the constitutional hyperlaxity by examining the parental group -the same facial dystrophies, the same habits resulting in various disorders of general or cervical statics. At the level of the temporomandibular joint, the dysfunction is also accompanied by claudication by mandibulo-hyo-lingual tipping. The general and cervical statics of the baby are thus affected in the course of sleep. It is during paradoxical sleep that the baby's head tips on to the thorax, due to the resultant atonia of the neck muscles. The head, insufficiently supported on its cervical pillar accentuates the asphyxial mechanism provoked by the tipping of the lingual area on the epiglottis.(ABSTRACT TRUNCATED AT 250 WORDS)

We report a case of 13-year-old girl with short stature, microcephalus, blepharophimosis, ptosis, bilateral microphthalmia (more prominent in the right), hypogonadism, other minor anomalies, and severe mental retardation. Her mother had two spontaneous abortions. She was born as the second baby of dizygotic twins. The first baby died of diaphragm hernia and heart failure. Her body height, body weight and head circumference were below -3 SD. She did not have epicanthus inversus, hypoplastic teeth, heart anomalies, seizures, muscle weakness, and hearing loss. She was able to handle her wheelchair, but could neither understand nor speak meaningful words. When she looked at something in front of herself, she turned her face up and lifted the left eyelid with her own fingers. She had no somatic change of puberty. Laboratory and radiological examinations demonstrated a normal karyotype, normal bone age, findings of Chilaiditi syndrome, and absence of brain malformation on cranial CT. The serum levels of LH and FSH were high for age and those of estradiol and progesterone were low, suggesting immaturity of ovarian function. These findings suggested the ovarian functions might not get maturations. Hypogonadism has previously been reported in female cases of the blepharophimosis, ptosis and epicanthus inversus syndrome (BPES) type I, but not in those with the Ohdo blepharophimosis syndrome (OBS). Our case's condition differs from BPES because of the presence of mental retardation and the absence of epicanthus inversus. We also discuss the distinction from OBS, a disease entity of unknown etiology presenting with a variety of complications.
