Low formaldehyd-concentrations were measured in three Cologne schools (mean 1 = 0,4425; mean 2 = 0,5725; mean 3 = 0,1292 ppm). As the main sources of emission were identified formaldehyd-urea-bound chip-plates in acoustic-ceilings and wainscots. To study the connection between the complaints of pupils and CH20-emissions 1594 pupils of these schools were questioned using a specially elaborated questionnaire. The questions concerned multiple complaints and disturbances of health as well as their anamnesis in chronological relationship with school attendance. Compared to controls consisting of 497 pupils of a school, where no CH2O-emitting chip-plates were used, the inquiry showed a significant increase (p less than 0,00005) of so-called functional disturbances (headache, disorder of concentrating ability, dizziness, nausea), affections of the respiratory tract (irritation of the mucosa of the nose and the pharynx, dry cough) and irritation of the conjunctiva. In regard to the anamneses, the difference between the investigation-group and the control-group was even more significant and additional complaints such as somnipathy, abdominal pain, skin disease were observed frequently. Comparing the normal distribution of so-called functional disturbances in pupils found in literature, the examined group of this study showed an even higher rate of the relative accumulation. The repeated investigation in one school (n = 328) 8 months after removal of the emission-sources demonstrated a very clear reduction of complaints by an average of 71,2 per cent.

Air has been traditionally used as the negative contrast agent in double contrast barium enema (DCBE) examinations, but causes abdominal pain in the 24 h following the procedure. The frequency of post-procedural pain is less when carbon dioxide (CO2) is used as the negative contrast agent. We evaluated patients following DCBE examinations (using either air or CO2) by means of a questionnaire, to determine whether active drainage of gas altered the post-procedural pain. There was no difference in the pain experienced in the groups receiving CO2 with either active or passive drainage, or in the group receiving air with active drainage. Compared with the other groups there was a significantly higher incidence and severity of pain in the group receiving air and passive drainage. We conclude that active drainage of air following a DCBE examination is as effective as using CO2 in reducing post-procedural pain and swelling.

Prospective registry of newly diagnosed cases of insulin-dependent diabetes mellitus in subjects under 20 years began in 1988 in Aquitaine, Lorraine, Basse- and Haute-Normandie (population base = 2,288,018 inhabitants under 20). The registry gave a complete coverage of the population as the capture-recapture method gave a 98% yield. The mean annual incidence was 7.6/100,000 for the period 1988-1990. A specific survey aimed at describing clinical and biological presentation at diagnosis. The main symptom was polyuria in 98% of the cases, fatigue in 58% and weight loss in 44%. Abdominal pain was reported in 34% of the cases. Diagnosis was ascertained by measurement of plasma glucose, which was > or = 11 mmol/l in 95% of the cases and associated with ketonuria in 84% of the children. Coma in 13% of the children and acidosis (total CO2 < or = 18 mmol/l) in 48% showed the severity at diagnosis. Ketonuria and acidosis were significantly more frequent in the younger age group (0-4 yr). Diagnosis was made by a general practitioner in the majority of the cases; conversely insulinotherapy was initiated at the hospital in 95% of the cases. Initial insulin treatment was 2 daily injections. Following the French experience the collaborative network EURODIAB ACE has undertaken the same survey among the European Registries. Important geographical variations in incidence rates of IDDM in children has been reported across Europe but it is not known whether this interferes with presentation at diagnosis of the disease.

We have studied the cardiorespiratory changes produced by abdominal wall elevation (AWE) or carbon dioxide pneumoperitoneum (PN) in 20 women undergoing gynaecological laparoscopy. Arterial pressure, heart rate, lung/chest complicance and blood-gas tensions were measured 10 min after induction of general anaesthesia (T0), 10 min after abdominal distension in the supine position (T1) and 10 min after the Trendelenburg position was assumed (T2). Visual analogue scores for pain were recorded 1 and 6 h after the end of surgery. We found that lung/chest compliance was reduced significantly in group PN at T1 and T2 compared with both T0 and group AWE. Diastolic arterial pressure increased significantly in group PN at T1 and T2 compared with both T0 and group AWE, while it remained unchanged in group AWE. Arterial PCO2 increased significantly only in group PN after pneumoperitoneum, while oxygenation was almost unchanged in both groups. AWE patients had greater abdominal pain 1 h after surgery. Six hours after surgery pain was similar in the two groups. These data indicate that abdominal wall elevation reduced pulmonary compliance less than a pneumoperitoneum in patients undergoing gynaecological laparoscopy.

Hepatic porphyrias are characterized by neurological symptoms manifested by abdominal pain, neuropathies and mental aberrations. Porphyrins are ubiquitous and essential biochemical constituents of living beings acting as mediators of oxidation reaction in the metabolism of the steroid, drugs, environmental chemicals or as a mean of exchanging gases, such as oxygen and carbon dioxide between the environment and the tissue of the body using endogenous polypeptide properties. The different porphyrins arising from the arrangement of normal heme synthesis are characterized by an accumulation and excretion of specific intermediate porphyrins and/or of precursors exerting toxic effect, initiating cascades of generations of polypeptides, neurotransmitters and gut-brain axis peptide responsible for the symptoms of clinical status. We studied polypeptide levels in 27 patients (19 females, 8 males) presenting acute attack of hepatic porphyria: 2 with ALA dehydratase-deficient porphyria; 9 with acute intermittent porphyria; 12 with porphyria cutanea tarda and 4 with variegate porphyria. During acute attacks of porphyria, polypeptides were found to be constantly increased: vasoactive intestinal polypeptide (VIP); neurotensin (NT); substance P; pancreatic polypeptide; gastrin-releasing peptide; gastrin and motilin. Administration of the somatostatin (antagonizing polypeptide), which was undetectable or low before treatment, apparently alleviated the acute symptomatology. Elevated levels of polypeptides, at least partly, contribute to appearance of acute symptoms in porphyria patients.

The present report concerns a patient who had undergone nearly total pancreatectomy (95%) with pancreatic islet autotransplantation for intractable pain caused by obstructive chronic pancreatitis. Islets were prepared by a modified collagenase digestion and were cultured in vitro in Eagel's medium in 5% CO2 in air at 37 degrees C for 5 days. The resultant preparation, containing about 150,000 islets, was injected into the recipient's liver via the umbilical vein. No complication occurred from the pancreatectomy or transplant. Postoperatively, the patient had complete relief of the abdominal pain, and the insulin-independent condition remained with normal fasting blood glucose, and hemoglobin A1c for 11 months. Subsequently the fasting hyperglycemia was evident, and the patient began oral antidiabetic medication, but 2 year after transplantation the insulin-dependent condition demanded exogenous insulin (24 U). At present the fasting serum C-peptide level is 0.6 ng/ml and the HbA1c of 5.8% confirms the normoglycemic condition at the same insulin dose. Islet auto-transplantation should be considered as an adjunct procedure to prevent or ameliorate diabetes after total or nearly total pancreatic resection.

We report herein a case of spontaneous subcapsular hepatic hemorrhage which occurred in a 33-year-old woman 1 day after she had been delivered of her second child by cesarean section following an uneventful pregnancy. She complained of right upper quadrant pain on the 1st postoperative day, and computed tomography (CT) showed subcapsular low-density masses in both liver lobes, while extravasation was demonstrated by CO2 intraarterial digital subtraction angiography (IADSA). The hemorrhage was successfully controlled by transcatheter arterial embolization (TAE). However, on the 3rd day after TAE, an exploratory laparotomy was performed to establish an exact diagnosis to explain the persistent abdominal pain and abnormal liver function tests. Subcapsular hematomas in both lobes were confirmed and no visible laceration was present. The patient recovered gradually by spontaneous absorption of the hematomas and was discharged on the 22nd postoperative day. Spontaneous hepatic hemorrhage associated with pregnancy is a very rare complication, and establishing a correct diagnosis and initiating appropriate therapy are essential for this life-threatening disease.

Ruptured duodenal peptic ulcer is a serious complication of ulcer disease that occurs in approximately 5% of cases. Its emergency treatment is based on surgery, namely, simple closure or more definitive ulcer surgery. Laparoscopic repair of perforated duodenal ulcer with classic insufflation of CO2 is quick, simple, and technically feasible in most patients. We describe herein the operative treatment of a perforated duodenal ulcer in a 33-year-old man who presented to our Hospital with acute onset of severe abdominal pain. Wide peritoneal lavage and suture of the perforation was performed by gasless laparoscopic technique using a mechanical retractor obviating the creation of the pneumoperitoneum and of the sealed environment. This new approach enables the use of conventional instruments and provides a clear field of vision in the abdomen equal to that created by the traditional CO2 technique. Because there is not a pneumoperitoneum to maintain, the gasless technique permits a constant irrigation and suction of the abdominal cavity, a wide peritoneal lavage, and the continuous suction of fluid, blood, smoke, and humidity without losing the camera set. If indicated, it permits the laparoscopic repair of the perforation combined with the laparoscopic vagotomy in the same emergency setting. The present case proved it to be another abdominal procedure that can be carried out with all the technical and anesthesiological advantages of gasless minimally invasive surgery.

Among the potential hazards of laparoscopic surgery using electrocautery is the release of chemical by-products of incomplete tissue combustion into the pneumoperitoneum with subsequent transperitoneal absorption into the bloodstream and/or release into the operating room. The purpose of this study of patients undergoing laparoscopic cholecystectomy (LC) was twofold: (1) to assess the relationship between intraperitoneal concentration of carbon monoxide (CO) and blood levels of carboxyhemoglobin (COHb) and methemoglobin (MetHb), and (2) to assess the surgeon's inhalation of CO resulting from ambient smoke exposure. During LC with monopolar electrocautery, 21 patients were evaluated intraoperatively for intraperitoneal [CO] by sampling gas from a trocar, whereas arterial [COHb) and [MetHb] were determined perioperatively. The surgeon's venous blood was drawn pre- and postoperatively to assay [COHb] and [MetHb]. Patients completed visual analogue questionnaires 6 hours and 24 hours postoperatively to assess for adverse symptoms. Mean (+/- SEM) patient age and weight were 45 +/- 3 years and 84 +/- 4 kg, respectively. Mean duration of the operation was 69 +/- 5 minutes, and electrocautery was used for 3.0 +/- 0.3 minutes. Intraperitoneal [CO] rose to peak levels of 209 +/- 19 ppm at 50 minutes, whereas systemic [COHb] and [MetHb] were unchanged. The surgeon's systemic [COHb] and [MetHb] did not increase postoperatively. Nausea, abdominal pain, and fatigue scores decreased significantly between 6 and 24 hours postoperatively; however, there were no correlations between these symptoms and peak intraperitoneal [CO]. Although LC using electrocautery increases intraperitoneal [CO] to "hazardous" levels, systemic [COHb] and [MetHb] are not elevated by generation of intraperitoneal smoke. The surgeon's exposure to CO by the evacuation of smoke through laparoscopic ports is negligible. Production of smoke during LC using monopolar electrocautery, therefore, does not appear to pose a threat to either the patient or the surgeon.

Carbon dioxide laser laparoscopy offers a safe, effective, and relatively easy means of performing intraabdominal adhesiolysis. Sixty-five patients suffering from chronic lower abdominal pain have undergone laser laparoscopic adhesiolysis during the past 6 years. Fifty-three patients (84%) experienced symptomatic relief. The controversial association between abdominal pain and intraabdominal adhesions can be resolved only by performing a controlled prospective laser laparoscopic adhesiolysis study.
