Epidermoid cyst of the cecum: A case report

Pure, benign epidermoid cysts of the abdominal viscera are rare. There have been only six reports of epidermoid cysts of the cecum in the literature. A 31-year-old female with a previous cesarean delivery was admitted to our hospital with inguinal pain. After admission to the hospital, she was operated with the initial diagnosis of adnexal mass. During the operation, no adnexal pathology was identified. A heterogeneous mass originated from the posterior surface of the cecum was observed. It had no connection with the lumen. The mass was then removed with dissection. Macroscopically, the mass was 9x7 cm in diameter and wall thickness was 0.1 cm. The inner and outer surfaces were smooth. It was filled with a dense yellow, thick-fatty material with no tooth, hair, bone, or calcification areas. On microscopic examination, the inner lining was composed of mature keratinized stratified squamous epithelium with a granular layer. In view of the later findings, the case was reported as epidermoid cyst of the cecum. Although epidermoid cysts are rarely seen in visceral organs, this case is the seventh case of cecum-originated epidermoid cyst that has been reported in the literature. The histogenesis of epidermoid cyst is unknown. These cysts are generally accepted to be sequestration cysts that may be either congenital or acquired. Acquired epidermoid cysts are believed to be traumatic or iatrogenic. The cesarean delivery may have been a cause of this condition in the present case. On ultrasonographic examination, these cysts can be misdiagnosed as ovarian cysts.     

Acute Renal Failure and Mortality After Open-Heart Surgery in Infants

Acute renal failure (ARF) is a major complication in infants who undergo cardiac surgery. The aim of this investigation was to identify possible risk factors for ARF and mortality in this patients group. Out of 64 patients, 21 (32.8%) cases developed acute renal failure and overall mortality rate was 25%. The mortality rate was higher in the infants who developed ARF than those who did not (66.7% and 4.7%, respectively, p < 0.05). Also, ARF was positively correlated with mortality (r:0.70, p < 0.0001). The nonsurvivors had lower mean serum albumin than did the survivors (p < 0.05), and serum albumin level was negatively correlated with mortality (r = ? 0.34, p < 0.05). For the patients with serum albumin level < 3.5 g/dL, the unadjusted odds ratio for mortality was 4.3 (CI 95%:1.05 ? 17.86). Total bypass time and aorta clamping time were significantly longer in the nonsurvivor group than in the survivor group (p < 0.05 for both). In conclusion, the significant risk factors for mortality in these patients were development of ARF, low serum albumin level, and long total bypass and aorta clamping times, which may be predictive of poor prognosis.     

Ultrasonographic Maturation of Native Arteriovenous Fistulae: A Follow-Up Study

Background/aims. Ideal time needed for arteriovenous fistula (AVF) maturation is still controversial. In this study, we aimed to investigate the natural course of AVF maturation and also investigated the factors affecting AVF maturation. Methods. We studied 31 (21M/10F, mean age 55.8 ± 16.2) chronic renal failure patients. We evaluated the patients with color Doppler ultrasound examination before the fistula operation, at the first day, and at the first, second, third, and sixth months. Radial artery (RA) diameter, flow velocity, flow, resistance index, fistula vein diameter, flow velocity, and flow were measured. Results. Patency rates at the first post-operative day and the sixth month were 87.1% and 67.1%, respectively. Cephalic vein flow was 451.2 ± 248.6 mL/min at the first month and 528.6 ± 316.5 mL/min at the sixth month. Baseline RA diameter was lower in failing fistulas than that of patent fistulas. Failing fistulas were more common in women. Conclusion. Blood flow was enough for hemodialysis at the end of the first month. However, fistula maturation had continued until the end of the study; women and patients with low RA diameter are particularly prone to fistula failure. Therefore, especially in these patients, AVF must be created at least three or four months before the predicted hemodialysis initiation time.

A case of mitral stenosis complicated with seronegative Brucella endocarditis

Brucellosis is a multisystemic disease. The most common cause of death from the disease is endocarditis. The aortic valve is most commonly affected. The disease rarely involves the mitral valve. A 30 year-old woman presented with complaints of chills and fever up to 38 degrees C at night, fatigue, palpitations, and dyspnea for the previous 3 weeks. Cardiac auscultation revealed a diastolic murmur in the mitral area. Her temperature was 38.3 degrees C. On echocardiographic examination, the mitral valve area was 0.62 cm (2) and an isoechoic mass thought to be a vegetation was detected on the anterior mitral leaflet. A diagnosis of infective endocarditis was made and vancomycin administration was commenced. Brucella melitensis was isolated in all three blood samples, however, the patient remained seronegative with Brucella agglutination titers of up to 1/160. The antibiotic therapy was then shifted to doxycycline (200 mg/day), rifampicin (600 mg/day), and ciprofloxacin (1000 mg/day). After 30 days of treatment, surgery was performed for the severely stenotic mitral valve and to remove the vegetation. The operation was successful. The postoperative period was uneventful. On the follow-up she had no complaints. In cases with Brucella endocarditis, after diagnosis, antibiotic therapy must be started immediately and when the clinical condition improves, surgical intervention should be performed when indicated.     

Treatment in patients with low traumatic pneumothorax ratio

Thoracostomy tube placement (TT) is currently one of the most important treatment modalities used in traumatic pneumothorax patients. In patients with low pneumothorax ratio (percentage), both follow-up without surgery and employing intervention when indicated may be appropriate choice. We presented the outcome of patients with low traumatic pneumothorax ratio treated by follow up without surgical intervention in our clinic. During the period from January 2000 until January 2002, 108 patients who were treated and followed with low percentage traumatic pneumothorax in Ankara Numune Hospital Thoracic Surgery Clinic were allocated into three groups due to blunt trauma of the thorax, penetrating-cutting instrument injury and gunshot injury. All patients were admitted to the clinic with the purpose of observation without surgical intervention and chest roentgenograms were taken at the sixth and twelfth hours and daily thereafter. TT was performed for 46 (43%) patients whose pneumothorax ratio increased during the observation period. TT was more frequent in patients with 20% percentage pneumothorax (69%) as well as with two or more fractured ribs (69%). Follow-up without surgical intervention may one of the appropriate modes of treatment in patients who have minimal traumatic pneumothorax.
