Right-sided segmental infarction of the omentum: clinical, US, and CT findings.

Clinical, ultrasound (US), and computed tomographic (CT) findings at hospital admission and follow-up were retrospectively studied in seven patients with right-sided segmental infarction of the omentum. In all patients, the presumptive clinical diagnosis was appendicitis, although in three patients cholecystitis and pyelitis were also considered. US revealed an ovoid or cakelike, moderately hyperechoic, noncompressible lesion adherent to the peritoneum and located at the level of the umbilicus, anterolateral to the right half of the colon. On CT scans, a corresponding, better defined area of fat interspersed with hyperattenuating streaks was found. No abnormality of bowel or appendix was seen. The clinical symptoms and abnormalities on US scans gradually disappeared in all patients. Because no patient underwent surgery, no histologic proof was obtained. In all patients, however, the clinical, US, and CT findings were similar and consistent. They corresponded to the abnormality called right-sided segmental omental infarction in the surgery and radiology literature and enabled exclusion of appendicitis, thus preventing unnecessary surgery.

[Percutaneous drainage in renal emphysema. Clinical case].

Renal emphysema is a rare and severe infection, that constitutes two clinical entities: emphysematous pyelonephritis and emphysematous pyelitis. We report a case in which the gas is localized both in the collecting system and in the parenchyma of the kidney. In our experience the percutaneous renal drainage has revealed to be able to dominate the infection but not to preserve renal function.

[Hemolytic properties of Escherichia coli strains isolated from cases of urinary tract infection and enteropathy].

Different strains of E. coli, that were isolated during years 1986-1990 from 217 urine samples in patients with asymptomatic bacteriuria, cystitis, cysto-pyelitis and pyelonephritis, appeared to be more frequently haemolytic (34.5%) than strains of E. coli isolated from faecal samples in patients with acute enteropathy. It was confirmed that the haemolysin production occurs during log -phase of bacterial growth. The degree of haemolysis can vary widely according to the strain involved. Agglutination tests, using 53 O-antiserum, showed a great variety of serogroups. Some of them (04, 018, 022) are prevalent among the haemolytic strains isolated from urine; some others (055, 0111, 075) are prevalent among the anhaemolytic strains isolated from urine and faeces.

Upper urinary tract infection: the current role of CT, ultrasound, and MRI.

This article reviewed some of the fundamental concepts in renal inflammatory disease. The difficulties in present terminology were reviewed and our approach discussed. The pathological underpinning of the acute-subacute infections were contrasted with those seen in the granulomatous diseases. The importance of CT in separating emphysematous pyelonephritis from emphysematous pyelitis and perinephric emphysema was stressed. Although ultrasound has been used in the past and is still of value in select situations, we prefer CT for assessment of renal infection. CT examinations show whether the disease is focal or diffuse, whether air is present, whether there is perinephric or pararenal extension, whether an abscess is present, and when the ideal time is for intervention. In severe renal infection in the adult, CT has shown the development of renal scars, perinephric extension, and the spontaneous drainage of Staphylococcus abscesses into nearby calyces.

[Corynebacterium suis infections in swine. 2. Morphological findings in the urinary tract with special reference to the bladder].

Morphological investigations of the urethra, urinary bladder (2 localizations), ureter, renal pelvis and kidneys were performed in sows with Corynebacterium suis infection. The first stages of the disease were characterized by changes of the transitional epithelium in the bladder where epithelial vacuolisation, goblet cell differentiation, leucocytic infiltrations, and haemorrhages occurred. In chronically affected animals different stages of a mucopurulent, partly erosive to ulcerative cystitis were observed. Furthermore, chronic cystitis was characterized by polypoid mucosal proliferation and bacterial accumulations. Ureter and urethra showed signs of a mild purulent inflammation. In the renal pelvis there was a severe fibrinopurulent and necrotizing pyelitis which was accompanied by bacterial invasions. The parts of the renal pelvis without desquamation of the transitional epithelium undergo mucoid degenerations. The final stage of the disease is characterized by severe fibrosing chronic interstitial nephritis leading to death of the animals due to uraemia.

Chronic urinary tract infection in dogs: induction by inoculation with bacteria via percutaneous nephropyelostomy.

Dogs were inoculated via percutaneous nephropyelostomy with bacteria isolated from canine patients with urinary tract infections (4 dogs were inoculated with Escherichia coli, 2 were inoculated with Proteus mirabilis, and 1 was inoculated with coagulase-positive staphylococci). At approximately monthly intervals after bacterial inoculation, bladder urine specimens were collected via antepubic cystocentesis, and renal pelvic urine specimens were collected via percutaneous nephropyelocentesis. Dogs were euthanatized between 89 and 294 days after bacterial inoculation. Extensive microscopic examination was conducted on the urinary tract of each dog. The dogs did not develop any of the common clinical signs of urinary tract infections (ie, increased frequency of urination, fever, craniodorsal abdominal [renal] pain, or malaise). Inflammation in the lower urinary tract of the dogs was more severe than that in the kidneys. Although pyelitis was present, extension into the outer medulla and renal cortex seemed to be confined to nephropyelostomy tracts. The most severe bladder lesion was found in the dog that developed cystic calculi after inoculation with coagulase-positive staphylococci.

Ureterocolonic anastomosis in clinically normal dogs.

Ureterocolonic anastomosis was evaluated in 13 clinically normal dogs. Urinary continence was maintained after surgery, and the procedure was completed without technique errors in all but 2 dogs. Three dogs died within 5 weeks (2 of undetermined causes and 1 of aspiration pneumonia and neurologic disease), and 1 dog was euthanatized 4 months after surgery because of neurologic signs. Two healthy dogs were euthanatized 3 months after surgery for light microscopic evaluation of their kidneys. Five dogs were euthanatized 6 months after surgery for light microscopic evaluation of their kidneys. Gastrointestinal and neurologic disturbances developed in 4 dogs at various postoperative intervals. Plasma ammonia concentration measured in 2 dogs with neurologic signs was increased. Plasma ammonia concentration measured in 5 dogs without neurologic signs was within normal limits. All 5 dogs, in which metabolic acidosis was diagnosed, had high normal or above normal serum chloride concentration. Serum urea nitrogen values were increased after surgery because of colonic absorption of urea. Serum creatinine concentration was increased in 1 dog 6 months after surgery. Individual kidney glomerular filtration rate was reduced in 38% (3/8) of the kidneys from 4 other dogs at 6 months after surgery. Of 5 dogs euthanatized at 3 to 4 months after surgery, 4 had bilateral pyelitis, and 1 had unilateral pyelonephritis. Six months after surgery, pyelonephritis was diagnosed in 40% (4/10) of the kidneys from 5 dogs. The ureterocolonic anastomosis procedure is a salvage procedure that should allow complete cystectomy. However, variable degrees of metabolic acidosis, hyperammonemia, and neurologic disease may result.

[Clinical study of carumonam].

To evaluate the clinical efficacy of carumonam (CRMN, AMA-1080), the drug was used in the treatment of 10 patients including 4 with pneumonia and each with acute tonsillitis, chronic bronchitis, Mycoplasma pneumonia, primary atypical pneumonia (PAP), chronic pyelitis, and acute cystitis. Since beta-lactam antibiotics were not active against Mycoplasma pneumonia and PAP, these diseases were excluded from the clinical efficacy evaluation of CRMN. Responses were excellent in 1 patient and good in 7. Side effects were not observed. The laboratory test recognized slight elevations of GOT, GPT and eosinophilia in 1 patient and a slight leucopenia in another upon the administration of CRMN.

[Clinical evaluation of cefmenoxime in internal medicine, with special reference to infection associated with hematological disorders].

Clinical evaluation of cefmenoxime (CMX, Bestcall) was performed against infections associated with hematological, respiratory tract and other disorders. Clinical effectiveness of CMX against severe infections with hematological disorders including sepsis, pneumonia, pyelitis and so on was 74.4% for good responses and against the respiratory tract infections, 96.2% for good responses was obtained. Neither objective or subjective side effects nor extreme abnormalities in laboratory tests were observed in these patients. It can be concluded, therefore, that CMX is one of the most useful drugs against infectious diseases associated with hematological disorders, respiratory tract and other disorders.

[Pathomorphological picture of various internal organs of rats after long-term exposure to toxic substances in raw coke gas].

The authors carried out morphological evaluation of a long-term action of toxic substances at low concentrations (about 1 NDS), contained in raw coke oven gas, i.e. gases: CO, H2S, SO2, NH3 and benzene, as well as dusts containing: C, SiO2, Pb and Cd on the liver and kidneys of three-month old male rats of the Wistar strain. The animals were exposed to the above toxic substances in an experimental chamber for 24 hr, and for 8 hr every day during 12 and 18 months. It was found that pathogenic action of the substances contained in raw coke oven gas was not the total action of all chemical components, but their complicated resultant. Significant differences in the intensity of morphological changes in lungs were observed between rats exposed for 8 hr ans 24 hr/day, in favour of the former. Such a relationship was not observed between 12 and 18 month exposition. Besides the catarrh of the air passages and cellular-fibrous changes in pulmonary alveoli, focal metaplasia of cells of bronchial epithelium was observed, which suggested the possibility of carcinogenic action of coke oven gases and dusts. No distinct morphological differences were found in the liver and kidneys between 8 and 24 hr exposition, whereas great differences were found between 12 and 18 months exposition. Chronic interstitial pyelitis was observed in kidneys after 18 month exposition.

Trigonal-colonic anastomosis: a urinary diversion procedure in dogs.

Trigonal-colonic anastomosis for diversion of urine into the colon was performed in 12 clinically normal dogs and in 10 incontinent dogs with diseases of the urinary bladder or urethra. Dogs were studied from 1 to 30 months after surgery. The surgical procedure was technically satisfactory. Fifteen of 22 dogs were studied with intravenous urography, and only 1 case of hydronephrosis was found. Pyelitis was a common histopathologic finding in both groups of dogs. Pyelonephritis developed in 30% of dogs, regardless of duration of anastomosis. Glomerular filtration rate was reduced in all dogs studied, but renal failure was infrequent. Values for blood urea nitrogen and serum inorganic phosphorus were elevated due to intestinal recycling of nitrogenous products and phosphate. Electrolyte imbalances were not a problem, but gastrointestinal disturbances developed in 3 of the 10 diseased dogs. Six of 10 diseased dogs survived from 9 months to more than 3 years. Trigonal-colonic anastomosis appears to be a satisfactory salvage procedure for incontinent dogs with diseases of the urinary bladder or urethra that do not respond to other forms of therapy.

[Clinical and laboratory studies on S-6437 (a new longacting granule of cephalexin) in pediatric field (author's transl)].

Clinical and laboratory studies on S-6437 were made, and the following results were obtained. 1. Thirty pediatric patients with various types of infections such as tonsillitis, bronchitis, pneumonia, cystitis, pyelitis, lymphadenitis colli and pyodermia were treated with S-6437 at the daily dosage of 50 mg/kg orally, the clinical effectiveness was 89.3%. 2. The peak blood level of cephalexin after a single oral administration (25 mg/kg) was observed after 4 hours and the average peak blood level of 10 cases was 7.4 microgram/ml. 3. The average urinary excretion rate of 5 cases was 71.2%. 4. Mild side effects were noticed in a few cases.

[Pathology of renal tuberculosis (author's transl)].

Introduction of specific chemotherapy and vaccination leads to a remarkable recession of renal tuberculosis in the younger age group. Renal tuberculosis is the result of a haematogenous spread of tubercle bacillus. Haematogenous spreading occurs immediately after primary infection, or, in elderly patients, in combination with recurrency of tuberculous foci in lungs and hilar-lymphnodes. Simultaneous metastasis in the skeleton, especially in the vertebrae, are observed in 30%. The incubation period between tuberculous spread and clinical manifestation of renal tuberculosis lasts several years, in the average 5-8 years, for calcareous kidneys it may last as long as 20 years and more, for tuberculous pyelitis only a few months. Today it is possible to treat renal tuberculosis with drugs (Streptomycin, PAS and INH). In 13% the cicatrisation is combined with obstruction of calices and partial hydronephrosis, in 7% with obstruction of the ureter and total hydronephrosis. Early chemotherapy may prevent the development of tuberculous hydronephrosis.

Leukocyte response to somatostatin in normals and patients with bacterial leukocytosis.

In normals and patients with acute bakterial leukocytosis synthetic somatostatin decreases cell count of stab neutrophils, neutrophils and eosinophils. After termination of somatostatin infusion a rebound phenomenon occurred. In healthy normals lymphocyte count increased during somatostatin infusion. This effect outlasts the end of infusion for more than 24 h. No significant effect could be demonstrated in patients with a bacterial leukocytosis.

Uncommon radiologic observations in renal milk-of-calcium stone.

Milk-of-calcium stone is a rare finding in the kidney. It is diagnosed radiologically based on the fact that the opacity takes a semilunar shape and layers according to the position of the patient. An unusual observations is that layering may require some time to take place and that the semilunar configuration may be found incidentally in the supine position as well.

Eosinophilic pyeloureteritis: report of a case.

A case is reported of ureteral obstruction that was owing to eosinophilic pyeloureteritis, a previously unrecorded entity. The microscopic findings of extensive fibrosis and a relatively mild eosinophilic infiltrate were similar to those found in a series of eosinophilic cystitis, which was reported recently from this laboratory. Also, local injury appears to initiate some examples of eosinophilic cystitis and in the present case there was a striking history of injury 1 month before the symptoms of ureteral obstruction.
