Estimating the cots required for neonatal intensive care.

Estimates of the number of cots required for neonatal intensive care have been based on recommendations made in 1971 in the Sheldon report, and there is concern that the recommendations are now out of date. Therefore changes in the use of neonatal care within one health region (North-east Thames) during the years 1972, 1974, and 1976 have been examined. It was found that new developments in the sophisticated care of very small and sick babies have placed greater demands on cots and other resources. More babies of very low birthweights are now being cared for in the two units in the region and the average length of stay in hospital is increasing. Criteria have been refined and brought up to date to estimate the likely requirements for neonatal intensive care cots, taking into account recent developments in the care of small babies.

When do pregnant women attend for antenatal care?

The case records of a representative sample of 313 women from four health districts in the North-east Thames Health Region were reviewed to determine the stage of pregnancy at which they contact antenatal services. Patients seeking care (when a blood specimen was obtained) after 20 weeks' gestation ranged from 6% to 26%. These women were more likely to be of higher parity and immigrants. Appreciable delays in obtaining an early blood specimen, or in referral to a hospital antenatal clinic, were due to delay by hospitals in giving appointments and, to a lesser extent, to slowness of general practitioners in referring patients or taking blood.

Hawaiian craniofacial morphometrics: average Mokapuan skull, artificial cranial deformation, and the "rocker" mandible.

Craniofacial morphology and cultural cranial deformation were analyzed by the computer morphometric system in 79 adult Hawaiian skulls from Mokapu, Oahu. The average Hawaiian male was large, but similar in shape to the female. Both were larger than the present Caucasian, showed a greater dental protrusion, and possessed a larger ANB angle, flatter cranial base, and larger facial heights. Correlations in Hawaiian craniofacial structure were found between an increasing mandibular plane angle and 1) shorter posterior facial height, 2) larger gonial angle, 3) larger cranial base angle, and 4) smaller SNA and SNB angles. Of the 79 skulls studied, 8.9% were found to have severe head molding or intentional cranial deformation. Significant statistical differences between the molded group and the nonmolded group are, in decreasing significance: 1) larger upper face height, 2) smaller glabella to occiput distance, and 3) increased lower face height with deformation. The morphometric differences were readily seen by graphic comparison between groups. It is postulated that external forces to the neurocranium result in redirection of the growth vectors in the neurocranial functional matrix, including the cranial base, and secondarily, to the orofacial functional matrix. There is a possibility that the cranial deformation is a retention of the normal birth molding changes. The Polynesian "rocker jaw" was found in 81% to 95% of this populace. This mandibular form occurs only with attainment of adult stature and craniofacial form. This data agrees with the hypothesis that mandibular form is modified by the physical forces present and their direction in the orofacial functional matrix.

Rectally administered prednisolone--evidence for a predominantly local action.

Plasma prednisolone levels have been compared in healthy volunteers and in patients suffering from idiopathic proctocolitis after the administration of standard retention enemata containing either prednisolone-21-phosphate or prednisolone metasulphobenzoate sodium. The levels were significantly lower after the latter, irrespective of the presence or degree of activity of the disease. Prednisolone metasulphobenzoate appeared to be as effective as the 21-phosphate ester for the treatment of proctocolitis in the few patients where the two drugs were compared. It seems possible that the beneficial effect of the form of therapy is exerted predominantly locally, rather than by systemic action.

[Prophylaxis of gastroduodenal complications after renal transplantation (author's transl)].

Gastroduodenal bleeding or perforation following renal transplantation constitute a serious complication with a high lethality. 82 patients with terminal renal insufficiency were grouped in 4 categories with increasing gastroduodenal risk factors. Parameters for judging gastroduodenal risk consisted of gastric acid secretion, history and endoscopic demonstration of acute or chronic ulcer disease. 33 transplant candidates of groups I (hypochlorhydria, no ulcer) and II (normochlorhydria, no ulcer) were treated by medical prophylaxis alone. 23/33 were transplanted without prophylactic surgery, 1 patient in group II with erosive duodenitis before transplantation died from bleeding duodenal ulcer. Patients of group III (hyperchlorhydria up to 40 mval/h, MAO, no ulcer) received selective proximal vagomty, patients of group IV (hyperchlorhydria, 40 mval/h MAO and/or ulcer) underwent selective gastric vagotomy and 50% gastric resection. In 25 of 49 patients of group III and IV prophylactic operations were performed without serious complications. In 16 later on transplantated patients no gastrointestinal bleeding occurred. 2 patients of group III without gastric operation had minor bleedings out of erosive lesions in the gastric antrum and duodenal bulb, that could be managed by medical treatment. The positive experience with prophylactic gastric surgery in this limited number of patients seems to advocate a broader application of such a protocol. A considerable rise in gastric secretion was demonstrated in 19/21 patients during the first 3 years following the commencement of dialysis, BAO rose by an average of 72,2%, MAO by 41%. Thus, gastric analysis should be repeated once a year. Erosive gastritis and duodenitis seem to predispose for bleeding episodes after renal transplantation, this diagnosis should prompt prophylactic SPV.

Carcinoid of the uterine cervix: a case report with light and electron microscopic studies.

The case of a 33-year-old woman with primary carcinoid of the uterine cervix is reported. Primary carcinoid tumor is well known to occur in organs such as the gastrointestinal tract, lung and gonads. However, its occurrence in the uterine cervix is rare. To our knowledge, primary carcinoid of the uterine cervix has not been reported from the United States, although it has been well documented by non-American authors. Light microscopically, the tumor was characterized by formation of solid nests, trabeculae and glands. The cells therein showed argyrophil granules but were negative for argentaffin reaction. Electron microscopy revealed the presence of numerous neurosecretory granules and microfilaments. On the basis of light microscopic ultrastructural and cytochemical properties, the tumor is believed to arise from the normal argyrophil cell of the cervix and is regarded as an endocrine tumor, a member of the group of neoplasms called apudomas.
