Ventral hernia was induced surgically in sheep and either left unrepaired (5 animals), repaired with plastic mesh (20 animals) or with carbon fibre (20 animals). In unrepaired animals the hernia persisted. Three hernias recurred in the group repaired with plastic mesh, 2 as a consequence of sepsis. All the hernias repaired with carbon fibre remained sound over periods varying from 8 months to 2 years. There was a gradual invasion of the carbon fibres by collagenous tissue and thus a transition from one to the other of the stress of maintaining the abdominal wall intact.

To obviate any limitation in abdominal volume, the girth in 44 neonates was increased significantly by the insertion of either Marlex mesh or Prolene mesh as a permanent midline fascial prosthesis. Concomitant primary wound closure was then accomplished through mobilization of laterally based skin flaps. Without exception, the resultant coelom was adequately spacious, as reflected postoperatively by both ventilation and venous return being unimpaired. Four babies died, three as a result of antecedent cerebral hypoxia complicating diaphragmatic herniation and one as a result of sepsis. Indications for the procedure were a massive omphalocele in 31 infants, gastroschisis in nine and a huge diaphragmatic hernia in four. Wound dehiscence with exposure of the fascial prosthesis occurred twice, once because of a cautery burn of the skin and after minor wound infection in the second. Revision of the initial abdominal wall repair was required in both of these babies as well as for incomplete extrusion of Marlex mesh in three older children. Prolene is now preferred for fascial prostheses. Prime advantages of the technique include immediate enlargement of the peritoneal capacity, rare necessary for ventilatory support, maintenance of abdominal support by a fascial gusset, elimination of infectious complications attending more delayed closures of wound and peritoneum and the uncommon need for later operative revision.

Ninety-seven Royal Naval and Royal Marine officers and ratings undergoing repair of a unilateral inguinal hernia were randomized postoperatively into two groups: A, those who returned to full working duties 21 days after operation; B, those who returned to light duties 21 days after operation and to full duties at 3 months. Patients were reviewed at 3 and 12 months. One patient was withdrawn because of the development of late sepsis. Two patients in group B developed a recurrence of hernia within 1 year. No patient who returned to full duties at 21 days was unable to do any duty assigned to him. In a concurrent trial 119 male civilian patients were treated in the same hospital under identical conditions. All patients were reviewed 21 days after operation and were randomized into two groups: C, those advised to return to work immediately; D, those given no advice. Patients in group C returned to work in a mean of 38 days (range 14-96 days), whereas those in group D returned in a mean of 71 days (range 14-280 days). There was no recurrence of hernia in either group within the review period. It is concluded that there is no contraindication to resuming physical work 3 weeks after the uncomplicated repair of a unilateral inguinal hernia, and that active encouragement shortens the interval before return to work.

Wound healing has been investigated in 373 patients undergoing surgery for obstructive jaundice and 760 anicteric patients undergoing cholecystectomy. Reduced wound healing manifested by a higher frequency of wound dehiscence (3.2 per cent vs. 0.5 per cent) and incisional hernia (10.3 per cent vs. 1.8 per cent) was seen in the jaundiced patients. The factors related to this reduced wound healing have been analysed by univariate and multivariate analysis. The independent factors related to wound dehiscence in the 373 jaundiced patients were: an initial low haematocrit (less than 30 per cent), an initial low plasma albumin (less than 30 g/l], a history of pancreatitis, a malignant obstructing lesion, and postoperative wound and/or abdominal sepsis. Haematocrit, albumin and postoperative wound and/or abdominal sepsis were also independent factors for incisional hernia. A raised plasma bilirubin was not of independent significance for either wound dehiscence or incisional hernia. It is concluded that reduced wound healing occurs in jaundiced patients and that this is due to the associated features of poor nutritional status (manifested by low haematocrit and low albumin) and malignancy and not to the raised bilirubin per se.

Some newborn infants with either primary or secondary persistent pulmonary hypertension (PPHN) remain hypoxemic, hypercarbic, and acidotic despite therapeutic efforts. In autopsies of 23 infants who had PPHN, diffuse platelet-fibrin thrombi were present in the pulmonary microcirculation of eight (15.2 +/- 18.1 thrombi/cm2 lung tissue) and absent in 15 (0.2 +/- 0.3 thrombi/cm2 lung tissue), (P less than 0.004). Diagnoses in group A (thrombi) were pneumonia and sepsis (four patients), meconium inhalation (3), and primary PPHN (1); and in group B (no thrombi) pneumonia and sepsis (4), meconium inhalation (4), primary PPHN (4), hyaline membrane disease (2), and diaphragmatic hernia (1). The only significant differences between the two groups were the response to tolazoline infusion as assessed by changes in partial pressure of arterial oxygen (PaO2) and the platelet counts. Group A responded less favorably to tolazoline (14.8 mm Hg vs 83.6 mm Hg; P less than 0.05) and had lower platelet counts (51,000/microliter vs 128,000/microliter) (P less than 0.01) than group B. No significant differences could be detected in Apgar scores, duration or mode of mechanical ventilation, oxygen requirements, arterial blood gas tensions or pH, systemic arterial blood pressure, coagulation profile, amount of blood product transfusions, or intravascular catheter use. Pulmonary microthrombi should be added to the list of mechanisms for PPHN and may explain why some infants do not respond well to therapeutic efforts aimed at vasodilation. Thrombocytopenia and failure to respond to pulmonary vasodilators might suggest the diagnosis.

Clinical evaluation of cefmetazole were made in the treatment of bacterial infections in the newborn infants and the following results were obtained. 1) Five infants, 7 approximately 58 days of age, received a single intravenous one-shot injection of 22.2 approximately 24.5 mg/kg dose of cefmetazole, and blood concentrations were determined. The average level was 62.6 micrograms/ml (30 minutes), 46.3 micrograms/ml (1 hour), 26.8 micrograms/ml (2 hours), 8.7 micrograms/ml (4 hours) and 2.4 micrograms/ml (6 hours), and T 1/2 was 87.7 minutes. Almost similar values were obtained when the drug was given by a 30-minute drip infusion and sufficiently exceeded the MIC to the bacteria to which cefmetazole was indicated. 2) In two patients, who had been operated for choledochal cyst and received an intravenous drip infusion of the drug, the persistence of the blood concentration was remarkably long, T 1/2 being 192 and 222 minutes, respectively. This problem still remains to be elucidated. 3) The following 22 patients were treated with an intravenous one-shot or drip infusion of cefmetazole, i.e., 45.6 to 107.1 mg/kg divided in 2 approximately 3 doses; 14 patients aged 1 to 21 days, 2 aged 1 to less than 2 months, 3 aged 2 to less than 3 months and 3 aged older than 3 months. However, in purulent meningitis, larger dose was given intravenously 6 times daily. Diseases included sepsis (4 cases), purulent meningitis (3), peritonitis (1) SSS syndrome (3), subcutaneous abscess (2), urinary tract infection (8) and Salmonella enteritis (1), and their causative organisms were E. coli (13 strains), K. pneumoniae (1), S. typhimurium (1), S. aureus (6) and group B Streptococcus (1). Overall efficacy rate in 22 cases was 90.9%. i.e., excellent in 11, good in 9 and failure in 2. Two cases of failure were a patient with peritonitis and visceral eventration due to umbilical hernia and a patient with a chromosomal aberration and urinary tract infection caused by E. coli. Reasons for such a treatment failure appeared to reside in host factors. 4) Adverse reactions included each one case of skin rash and diaper rash, 3 cases of eosinophilia and 5 cases of elevation of transaminase levels, all of which were mild and transient. 5) Based on the above results, cefmetazole is considered to be a potent new antibiotic which should be indicated as the first choice drug in the treatment of neonatal bacterial infections. The recommended dosage is as follows: 50 mg/kg given intravenously 6 times daily for bacterial meningitis and 20 approximately 25 mg/kg intravenously or by a drip infusion 2 to 3 times daily for other infections.

Almost all types of newborn respiratory failure are reversible. However, supportive treatment (oxygen and positive airway pressure) can damage the lung, and newborn respiratory failure remains a major cause of morbidity and death in infants. Prolonged extracorporeal membrane oxygenation (ECMO) provides life support while allowing the lung to "rest." We have used ECMO in 45 moribund newborn infants; 25 survived. Neonatologists referred patients who were unresponsive to maximal therapy. The right atrium and aortic arch were cannulated via the jugular vein and carotid artery. Heparin was infused continuously to main activated clotting time at 200 to 300 seconds. Airway oxygenation and pressure were reduced to low levels. Primary diagnoses were hyaline membrane disease, 14 (6 survived, 8 died); meconium aspiration, 22 (15 survived, 7 died); persistent fetal circulation including diaphragmatic hernia, 5 (3 survived, 2 died); and sepsis, 4 (1 survived, 3 died). Growth, development, and brain and lung function are normal in 20 of 25 survivors. ECMO decreased newborn respiratory failure mortality and morbidity rates in this phase I trial. A controlled randomized study is underway. The results suggest that ECMO may be effective in older patients if used before irreversible lung damage occurs.

Early-onset infection findings caused by Group B Streptococcus occur within 24 hours of birth (60 per cent of cases) but they may appear anytime during the first 5 days of life. In our experience early-onset infection affects both preterm and term neonates. The Authors report the usual clinical signs described for bacterial infections. Unusual findings are also reported: among 34 infants with early-onset infection, the congenital diaphragmatic hernia was associated with GBS septicemia in two neonates; beads of perspiration were the first only clinical finding in one neonate too. Two cases of late-onset infection are also reported.

Although liposuction is considered to be a relatively safe procedure, several deaths and nonfatal serious complications such as sepsis, toxic shock syndrome, thromboembolic disease, fat emboli, and adult respiratory distress syndrome have been reported. In the present study, we have investigated a wide variety of components belonging to the coagulation, fibrinolytic, plasma kallikrein-kinin, and complement systems in 22 patients undergoing syringe-assisted liposuction using the superwet or tumescent technique. In spite of a relatively high mean aspirate volume (2,648 ml), only small changes over time well within the normal range were found for the different parameters. In nine randomly selected patients, we also measured interleukin 6 and tumor necrosis factor-alpha. The size of the interleukin-6 peaks was found to be of the same order of magnitude as those measured in patients undergoing hernia repair or percutaneous cholecystectomy but lower than those in patients undergoing open cholecystectomy, breast reduction, or breast reconstruction. Tumor necrosis factor-alpha was not detected in any sample in any of the patients. We conclude that syringe-assisted liposuction with the present aspirate volumes using the superwet or tumescent technique represents a small to moderate surgical trauma without clinical significant activation of the cascade systems.

In acute hypoxemic respiratory failure of term and near-term neonates, extra- and intrapulmonary right-to-left shunting contribute to refractory hypoxemia. Inhaled nitric oxide (NO) decreases pulmonary arterial pressure and improves ventilation-perfusion mismatch in a variety of animal models and selected human patients. We report on 10 consecutive term and near-term newborns with severe acute hypoxemic respiratory failure due to diaphragmatic hernia, meconium aspiration syndrome, group B streptococcus sepsis, pneumonia or acute respiratory distress syndrome, who received increasing doses of inhaled NO (up to 80 ppm) to improve the arterial partial pressure of oxygen (PaO2). The response to NO and the optimum NO concentration which improved PaO2 varied considerably between patients. Improvement of PaO2 was absent or poor (less than 10 mm Hg) in the 4 newborns with meconium aspiration syndrome and in 1 patient with congenital diaphragmatic hernia, while in the other 5 patients inhaled NO increased the mean (+/- SE) PaO2 from 41 +/- 6 to 57 +/- 9 mm Hg (P < 0.05). Optimum NO concentrations determined by dose-response measurements performed during the first 8 hr of NO inhalation were 8-16 ppm except for 2 newborns with congenital diaphragmatic hernia who required 32 ppm to effectively increase PaO2. Four of the 5 patients in whom the PaO2 rose by more than 10 mm Hg received inhaled NO for extended periods of time (5 to 23 days) with no signs of tachyphylaxis. The optimum NO concentration dropped to less than 3 ppm after prolonged mechanical ventilation or when intravenous prostacyclin was given concomitantly.(ABSTRACT TRUNCATED AT 250 WORDS)
