Massive kidney infarct, due to total occlusion of the main artery, is not a frequent process in clinical urology. The most frequent causes are endocarditis, arteritis, atheromatosis and traumatisms. The complete blockage of the renal artery means that the tissue irrigated by the same is bloodless and prone to necrosis and it must be taken into account that although the renal parenchyma cannot withstand for more than 1 to 2 hours the lack of a blood supply, the obstructions or ischemias of shorter duration cause tissue disorders of greater or lesser importance, affecting more quickly and more intensely the cells of the tubules, than those of the glomerules and later the connecting tissue. Clinically, kidney infarcts may sometimes go unobserved and on many other occasions their symptoms are by no means typical although the most characteristic feature is a more intense, sharp, acute pain with macroscopic hematuria, proteinuria and cylindruria and, in the radiological exploration, kidney "silence" but with the excretory duct intact shown by means of retrograde uretero-pyelography. The kidney angiography will reveal the existence of the arterial obstruction, with the resulting avascular image. Extrapremature surgical treatment would be ideal in the cases of massive infarct but this would also require an extrapremature diagnosis, which would enable the embolectomy (where necessary to be carried out, thereby saving the kidney. However, under normal working conditions, taking into account the period of time which inevitably elapses between the patient feeling pain in the kidney and his reaching the Emergency Department and the necessary examinations being carried out which enable the correct diagnosis to be made, the number of hours which have passed make attempts at conservative surgery completely useless. The authors present the case of a 37-year old patient who, 15 days after presenting a picture of right kidney colic, went to the Emergency Department in our Centre where the doctor on duty merely performed a symptomatic treatment and the patient was not admitted to our Department until several days later. In the different radiourographic examinations carried out, right kidney mutism was observed, as well as the permeability of the excretory duct. The aortography revealed the total occlusion of the right renal artery. As more than 20 days had elapsed since the patient first presented the colic pain and before we examined him, there was no other therapeutic solution but the performing of a nephrectomy. The examination of the organ removed confirmed the diagnosis but the origin of the arterial obstruction could not be clarified for sure.

The problems arising from the discovery of a colorectal tumor during an infectious endocarditis caused by Streptococci D have rarely been mentioned in the surgical literature. The frequency of association of an asymptomatic colorectal tumor and of a Streptococcus bovi endocarditis is now undisputed. This notion implies the systematic search for an intestinal lesion (adenoma or carcinoma) in case of endocarditis or septicemia without involvement of the valves, caused by a streptococcus of group D. The authors report about 3 cases of enterococcal (1 case) and S. bovis (2 cases) infectious endocarditis revealing a colic adenocarcinoma (2 cases) and a villous adenoma (1 case), all being perfectly latent. The specific therapeutic problems arising from this association are outlined, including the antibiotic therapy, the role of the anticoagulant treatment and the priority given to valve surgery in case of hemodynamic instability.

Endocarditis due to the streptococcus Bovis is an affection which is more and more often recognized and whose link with the colic tumor pathology has been well established those last few years and confirmed in this study with a frequency of 60 p. cent. However, few studies have stated the gravity of the heart affection in streptococcus Bovis septicaemias. In this series of 10 streptococcus Bovis septicaemias, the valvular affection is frequent and serious. The vegetations are found in 9 cases out of 10. The aortic affection is slightly more frequent (8 times out of 10), against 7 times out of 10 for the mitral affection (double mitroaortic affection, 6 times). A valve replacement due to sub-acute or chronic cardiac failure was necessary in 6 cases out of 9, that is 66 p. cent. The mortality was nil.

Multiple visceral aneurysms complicating periarteritis nodosa are considered characteristic, though not pathognomonic, on arteriography. This arteriographic pattern has been described with hairy-cell leukemia, collagen vascular disorders, and atrial myxoma, but, to our knowledge, has not been previously reported with subacute bacterial endocarditis. A patient with enterococcal endocarditis sustained separate intra-abdominal hemorrhages, 24 hours apart, from aneurysms of the middle colic and left colic arteries. Sterile vessel cultures with inflammatory infiltrates, decreased complement levels, positive rheumatoid factor, and arteriographic evidence of multiple visceral aneurysms suggest the vasculitis was immunologically mediated and not mycotic. Antibiotic therapy after control of hemorrhage controlled abdominal symptoms.

Fifty-three cases of infective endocarditis are reported: 10 definite, 33 probable, 10 possible. There were: 35 males, 18 females, mean age: 66 +/- 14 years. Twenty-three patients had a known valve involvement, 21 a recently diagnosed valve involvement, 9 a prosthetic valve. Fifty patients had fever, 43 had a regurgitating murmur, 28 weakness and weight-loss, 13 cutaneous lesions, 11 arthritis, 8 splenomegaly, 3 ocular lesions. The portal of entry was suspected or confirmed in 37 cases: intestinal in 12 cases, dental in 11 cases, cutaneous in 7 cases, urinary tract infection in 6 cases, upper respiratory tract infection in 1 case. The micro-organism was found in 45 cases: 10 oral streptococci, 12 D bovis streptococci, 6 enterococci, 5 aureus staphylococci, 3 coagulase-negative staphylococci, 2 Coxiella burnetii, 7 other bacterias. Blood-cultures were negative in 8 cases. Precordial echocardiography found vegetations in 27 native valves and 9 prosthetic alterations. Ten patients had neurologic complications, 27 cardiac complications, 8 acute renal failure. Nine patients needed cardiac surgery, 6 died. Our results, compared with those in the literature, showed older age, a higher frequency of digestive portal of entry and of D bovis streptococci, frequently associated with a colic tumour.

The association of colorectal carcinoma and septicemia or endocarditis by Streptococcus bovis is well known. Nonetheless, other localizations of infection by Streptococcus bovis have not been associated with colorectal carcinoma. The case of association of colon neoplasm with infection by Streptococcus bovis localized in the surgical wound of resection of a prostate adenoma by the transvesical route carried out four months previously is presented. Possible intraoperative bacteremia colonizing the surgical wound due to colic compression during surgery may have been the cause. This localization of infection by Streptococcus bovis should be taken into account in screening of colorectal carcinoma.

The authors report about 3 cases of bovis endocarditis revealing a colic carcinoma. This morbidity confirms the need for routine digestive investigations in endocarditis due to group D streptococci and eventually a liver disease.

We report the case of a 63-year old patient presenting five infective endocarditis (IE) in a 13-years period, with different types of streptococcus. No entrance way had been found until the last relapse occurring on mitro-aortic bioprosthesis. This recurrence leads to the diagnosis of caecal adenocarcinoma by coloscopy, preceded and guided by PET scanner. It seems to be the initial entrance way which had been unrecognized because of its small size and its particular location, that is very difficult to observe by coloscopy. Recurrent streptococcus IE are rare and severe. When a gut or colic tumor is suspected, PET scan seems to be helpful in etiological survey.

Cat scratch disease is caused by Bartonella henselae, a bacterium transmitted to humans from cats through a scratch or by fleas. In 90% of cases, the clinical presentation is that of classical cat scratch disease where an adjacent lymph node is infected. Atypical manifestations include prolonged fever, liver and spleen abscesses, infective endocarditis, central nervous system involvement etc. We present a 6 years old girl who suffered from L2 vertebral osteomyelitis and epidural abscess, initially presenting as colic left waist pain, with no back pain or high fevers. During the process of diagnosis, she recovered without surgical intervention or antibiotic treatment. A review of the literature indicates that among the wide spectrum of clinical manifestations of cat scratch disease, skeletal involvement is rare. However, in cases of osteomyelitis, vertebrae are a common site as well as formation of a contiguous phlegmon. Although no studies have investigated the efficacy of different treatment regimens, all patients presented were treated with antimicrobial combinations and recovery rates were high. In view of the patient presented here, it is questioned whether the high recovery rates are a result of efficient antibiotic treatment or due to a benign natural course of the disease.
