From November 1970 to August 1974 small intestinal bypass was performed in 475 patients for morbid obesity with an operative mortality of 1.6%. Immediate postoperative complications were superficial wound infection (17 patients), pulmonary complications (seven patients), cardiac complications (five patients), wound dehiscence (nine patients), intestinal tract fistula (four patients), and miscellaneous complications (14 patients). Delayed complications included hypokalemia (28%), hypocalcemia (9%), anemia (11%), calcium oxalate urinary calculi (6%), gout (2%), and hepatic failure (1.4%). Fourteen patients died of late complications. Ventral incisional hernia occurred in 3% of the patients; failure to lose sufficient weight in 21%, all but one occurring in patients with end-to-side shunts. Thirteen end-to-side shunts have been converted to end-to-end shunts because of insufficient weight loss. A team concept is important in the handling of the morbidly obese. Small bowel bypass is effective in producing sustained weight reduction in these patients. Careful and continued study of these patients for the rest of their lives is of paramount importance.

Thoracic discal hernia is a rare condition which in most cases is associated with radiologic calcifications of the disc, the nature of which remains unclear. However, it is generally accepted that the calcifications consist of apatite. In our observation a calcified discal hernia caused progressive paraparesis. The fact that it occurred in a patient with diffuse chondrocalcinosis suggests that the discal calcification could be due to calcium pyrophosphate deposition.

The analysis of the descriptive data from the present trial leads to the following conclusions. A statistically detectable influence of the risk factors for advanced age (for Fraxiparin) are body weight above 80 kg (for calcium heparin), and malignant disease on the development of postoperative DVT was observed. In general, some influence of these risk factors persisted even though prophylactic medication was administered. The statistical considerations on risk factors do not permit any predictions for the individual patient concerning the possible risk of developing DVT. The levels of transaminases and gamma-GT increased by 20 to 30% in both groups during the treatment period. The occurrence of wound hematoma in patients operated on for hernia compared with patients with other surgical interventions revealed a clear dependence of this parameter on the type of operation performed. In keeping with other tolerance data no differences between either treatment was observed concerning the rate of wound hematoma in patients undergoing herniotomy. As to the frequency of DVT, a considerable difference between men and women was recorded in the Fraxiparin group. However, this observation needs to be confirmed in further trials. No difference was detected concerning the onset of DVT in either treatment group: 70% of the thromboses occurred within 3 days after surgery. Significantly, fewer thromboses with clinical signs and fewer proximal vein thromboses occurred in the Fraxiparin group. This seems to be most important for the clinician, since it indicates a twofold effect of the LMW heparin Fraxiparin: Both the frequency of postoperative DVT and the severity of these complications were significantly reduced.

From 1989 to 1991, 480 patients undergoing general surgery under epidural anaesthesia were included in a multicentre, comparative, randomized, open-study designed to assess whether calcium nadroparin (Fraxiparine), one daily subcutaneous injection of 0.3 mL, i.e. 3,075 anti Xa IU per day, is more efficiency and better tolerated than a non-fragmented standard heparin (Calciparine), one subcutaneous injection of 0.2 mL t.i.d. 15,000 IU per day, for the prevention of postoperative deep vein thrombosis (DVT). The 480 patients, treated in 78 centres, were randomized in two groups (Fraxiparine, n = 241; Calciparine, n = 239). In both groups, treatment was started two hours after the end of the surgical procedure. Hernia repair and prostatic surgery accounted for 60% of operations. Thromboembolic events were detected by clinical examination performed at regular time intervals and by a systematic exam (doppler and rheoplethysmography or ultrasonogram) at the end of the treatment. Both agents demonstrated a similar efficiency. There was only one case of DVT, confirmed by phlebography in the Fraxiparine group. Tolerance was good in both groups. The proportion of patients requiring a transfusion was low (3% in each group). Hematuria was relatively frequent (33% in the Fraxiparine group and 28% in the Calciparine group), however these rates were related to prostatic and urinary incontinence surgery. This study, including a wide series of patients undergoing general surgery under epidural anaesthesia, demonstrates that efficiency and tolerance of one daily injection of Fraxiparine are similar to those of three daily injections of Calciparine. It it concluded that Fraxiparine improves of the patient's comfort and decreases the nursing work load.

Calreticulin is a ubiquitous Ca2+ binding protein, located in the endoplasmic reticulum lumen, which has been implicated in many diverse functions including: regulation of intracellular Ca2+ homeostasis, chaperone activity, steroid-mediated gene regulation, and cell adhesion. To understand the physiological function of calreticulin we used gene targeting to create a knockout mouse for calreticulin. Mice homozygous for the calreticulin gene disruption developed omphalocele (failure of absorption of the umbilical hernia) and showed a marked decrease in ventricular wall thickness and deep intertrabecular recesses in the ventricular walls. Transgenic mice expressing a green fluorescent protein reporter gene under the control of the calreticulin promoter were used to show that the calreticulin gene is highly activated in the cardiovascular system during the early stages of cardiac development. Calreticulin protein is also highly expressed in the developing heart, but it is only a minor component of the mature heart. Bradykinin-induced Ca2+ release by the InsP3-dependent pathway was inhibited in crt-/- cells, suggesting that calreticulin plays a role in Ca2+ homeostasis. Calreticulin-deficient cells also exhibited impaired nuclear import of nuclear factor of activated T cell (NF-AT3) transcription factor indicating that calreticulin plays a role in cardiac development as a component of the Ca2+/calcineurin/NF-AT/GATA-4 transcription pathway.

Milk of calcium cholecystitis is a rare disease predominantely of adults. The term designates a pathologic accumulation of calcium carbonate in the gallbladder, much rarer in the common bile duct as well. The patient may be symptom-free. If present the symptoms may be very mild or as an acute biliary pain, transient jaundice and mild attack of pancreatitis. Calcium in the bile may be liquid or it may form a paste-like mass. Both may be seen on a plain X-ray of the abdomen. The stone or stones of calcium carbonate may be formed so that they may cause an obstruction of the gallbladder outflow tract or cystic duct or pass into the common bile duct or into the duodenum. [figure: see text] We present a 71 year old male who was admitted for inguinal hernia repair but in whom a mild hiperbilirubinaemia was found and then on ultrasonography a gallbladder stone was diagnosed. We performed a hernia repair as well as cholecystectomy and operative cholangiography which turn to be normal. Within an almost normal gallbladder a gray-whitesh paste-like mass was found composed of calcium carbonate. The postoperative recovery was uneventful and serum bilirubin become normal. Histology of gallbladder showed chronic nonspecific cholecystitis.

Nitric oxide (NO) plays a major role in the modulation of perinatal pulmonary vascular tone. Congenital diaphragmatic hernia (CDH), a major cause of severe persistent pulmonary hypertension of the newborn (PPHN), is often refractory to inhaled NO. Alterations in NO/cyclic guanosine 3',5' monophosphate (cGMP)-mediated pulmonary vasodilatation may contribute to PPHN in CDH. We assessed NO/cGMP-mediated pulmonary vasorelaxation in vitro in 140-d gestational lamb fetuses with surgically created left CDH (term = 147 d) to age-matched controls. Relaxation of fourth generation intralobar pulmonary artery rings in response to the endothelium-dependent vasodilator, acetylcholine (ACh), and to the specific inhibitor of cGMP-phosphodiesterase (PDE), zaprinast, did not differ between the two groups. By contrast, relaxation in response to the calcium ionophore A23187 was impaired in CDH as compared with control animals. Relaxation in response to the NO donor sodium nitroprusside (SNP) (a direct activator of soluble guanylyl cyclase [sGC]) was also impaired in CDH animals as compared with controls. Repeating the challenge increased vasorelaxation in response to SNP in CDH as compared with control animals. Immunohistochemistry revealed the presence of endothelial NO-synthase in the endothelium of pulmonary arteries from both control and CDH animals. We conclude that endothelium-dependent vasodilatation in response to ACh and A23187 was differently affected in the fetal surgical CDH-lamb model. Furthermore, activity of sGC but not that of PDE was impaired in CDH animals. PPHN and decreased inhaled NO responsiveness in CDH may involve decreased sGC activity.

Although most lesions that occur in the chest have a nonspecific soft-tissue appearance, fat-containing lesions are occasionally encountered at cross-sectional computed tomography (CT) or magnetic resonance imaging. The various fat-containing lesions of the chest include parenchymal and endobronchial lesions such as hamartoma, lipoid pneumonia, and lipoma. Endobronchial hamartoma usually appears at CT as a lesion with a smooth edge, focal collections of fat, or fat collections that alternate with foci of calcification. Mediastinal fat-containing lesions include germ cell neoplasms, thymolipomas, lipomas, and liposarcomas. The most frequent CT manifestation of the germ cell neoplasm teratoma is a heterogeneous mass with soft-tissue, fluid, fat, and calcium attenuation. Cardiac lesions with fat content include lipomatous hypertrophy of the interatrial septum and arrhythmogenic right ventricular dysplasia. Diagnosis of the former is made with CT when a smooth, nonenhancing, well-marginated fat-containing lesion is identified in the interatrial septum. Finally, fat may herniate into the chest at several characteristic locations. When such a lesion is identified, the time required for differential diagnosis is significantly reduced, often allowing a definitive radiologic diagnosis. Sagittal and coronal reformatted images can add valuable information by showing diaphragmatic defects and hernia contents.

Human Fibrin Glue (HFG) is made of two components contained in separate vials: a freeze dried concentrate of clotting proteins, mainly fibrinogen, Factor XIII and fibronectin (the sealant) and freeze dried thrombin (the catalyst). The first component is reconstituted with an aprotinin solution that inhibits tissue fibrinolysis. The second component (thrombin), available in 500 I.U. concentration, is dissolved with calcium chloride. It is so a set of substances involved in the hemostatic process and in the wound healing, conferring to the product the following important properties: hemostatic and sealing action, through the strengthening of the last step of the physiological coagulation; biostimulation, which favors the formation of new tissue matrix. The indications for the use of human fibrin sealant are numerous and present in all the surgical branches. A randomized controlled trial of 50 patients undergoing hernia repair according to Lichtenstein's technique under local anesthesia was performed. Patients had concurrent coagulopathies as a consequence of liver disease or long-term treatment with anticoagulants for ischemic heart disease or cardiac rhythm disturbances. Coagulopathies were defined according to the following criteria: prothrombin time < 10.5 seconds, activated partial thromboplastin time < 21 seconds, and fibrinogen < 230 mg/dL. Patients were randomized in a 1:1 ratio with (group A) or without (control group B) use of human fibrin glue: Postoperative hemorrhagic complications were significantly reduced in group A (4%) compared with group B (24%). This study showed that human fibrin glue is effective in preventing local hemorrhagic complications after inguinal hernia repair in patients with concurrent coagulation disorders.

Fetal intervention aims to improve lung growth and survival in congenital diaphragmatic hernia (CDH). Airway smooth muscle (ASM) is important in lung development: ASM progenitors produce a key growth factor for lung morphogenesis (fibroblast growth factor 10); ASM contractility is also coupled to growth. ASM hyperreactivity occurs in postnatal CDH and may exacerbate barotrauma via impaired lung compliance. We hypothesize that ASM hyperreactivity and its sequelae are based on an early developmental lesion of ASM activity in hypoplastic lung. Sprague-Dawley rats were fed 100 mg nitrofen on Day 9.5 of pregnancy to induce lung hypoplasia in offspring (controls had vehicle alone). Normal and hypoplastic lung primordia were cultured from Day 13.5 of gestation at 37 degrees C in 5% CO(2) and loaded at 54 or 78 h with Ca(2+)-sensitive indicators: Fluo-4 for confocal imaging and Indo-1 or Fura-2 for photometric measurements of [Ca(2+)](i). Hypoplastic lung features spontaneous propagating ASM Ca(2+) transients with reduced frequency, increased amplitude, and significantly prolonged plateau duration, relative to control lung. Nonetheless, hypoplastic lung exhibits normal requirement for extracellular calcium entry and intracellular calcium release in initiation and regulation of ASM Ca(2+) waves. Early ASM dysfunction in lung hypoplasia is apparent as specific anomalies of Ca(2+) transients that indicate a problem with plasmalemmal ion channels/action potential generation. Elucidation of such an ASM lesion may allow pharmacologic amelioration not only of ASM hyperreactivity and its sequelae, but also of hypoplastic lung growth itself.
