Electrical nerve stimulation in the management of enterocutaneous low-output fistulas: a report of two cases.

Two patients with low-output enterocutaneous fistulas after surgery were treated with electrical nerve stimulation (ENS). Ultrasonography was useful for the application of this treatment method and for the charting of its progress. Fistula output diminished rapidly in both cases, and the closure of the track was achieved after several sessions of ENS. The procedure is simple and safe and is suggested as an option for the treatment of low-output enterocutaneous fistulas.

Scaphoid fractures and nonunions: a comparison between panoramic radiography and plain X-rays.

This study describes the diagnostic potential of the panoramic X-ray technique in the evaluation of scaphoid fractures and nonunions. Fifty-eight symptomatic wrists were examined using both plain X-rays and the panoramic procedure. The panoramic images showed in detail the line of the scaphoid fracture and nonunion in detail; they revealed four scaphoid fractures and five nonunions that were not shown clearly with plain X-rays. The panoramic technique is a useful complement to plain X-rays for the investigation of scaphoid fractures and nonunions.

Orthopantography of the wrist and the knee.

Initial experience with panoramic radiography of the wrist and the knee is presented. The technique offers potential new evaluation of these joints. A standard PA projection demonstrates the carpal bones with almost no superimposition. Additional projections permit more detailed demonstration of the scaphoid and wrist compartments. Similar panoramic studies of the normal knee demonstrated alternative images of the patella, the femoral condyles and tibial plateau. Orthopantography of the joints may provide additional information in the diagnosis of joints abnormalities.

Conservative treatment of large rectus sheath hematoma in patients undergoing anticoagulant therapy.

BACKGROUND: The purpose of this study was to describe our experience in the conservative management of large rectus sheath hematoma (RSH) in patients undergoing anticoagulation therapy. METHODS: This is a retrospective study of the medical histories of 12 cases of RSH (11 female, one male; mean age = 67.6 years). Seven patients were taking oral anticoagulants, three were taking intravenous unfractionated heparin, and two were taking subcutaneous low-molecular-weight heparin. Six patients had a history of coughing fits. Ultrasound examination and computed tomography (CT) was performed in all cases. RESULTS: Clinically, the majority of patients presented acute abdominal pain, infraumbilical masses, and anemic syndrome. Ultrasonography demonstrated nine of the 12 cases of RSH, and CT showed the hematoma in all 12 cases. Type II (five cases) and type III (seven cases) indicate moderate and severe hematomas, respectively. Excessive anticoagulation was observed in eight cases, and coagulation within correct ranges was seen in the remaining four cases. In five patients the normalization of coagulation was achieved by administering vitamin K1 and fresh frozen plasma. All cases of type III hematoma required blood transfusion. Conservative treatment was effective in all cases. CONCLUSIONS: RSH must be suspected in women of advanced age undergoing treatment with anticoagulants who present the clinical triad of acute abdominal pain, infraumbilical mass, and anemic syndrome. CT is the examination of choice for the diagnosis of RSH. Early diagnosis of RSH permits conservative management, even in the case of large hematomas with hemodynamic repercussions and avoids unnecessary surgical intervention.

Rectus sheath hematoma: diagnostic classification by CT.

A method of classification for hematomas of the rectus abdominis sheath (RSH) is proposed based on findings observed in CT in the 13 cases of RSH in the present study. Type I hematomas (five cases) are slight and do not require hospitalization. Type II (three cases) and type III (five cases) are moderate and severe hematomas, respectively, and do require hospitalization. The patients with type III hematomas were all undergoing anticoagulant therapy and presented with a picture of acute abdomen, and in all five cases blood transfusion was carried out. Ultrasonography and, in particular, CT permitted a correct diagnosis of RSH. RSH should be considered (anticoagulant therapy induced) in females with sudden abdominal pain to avoid unnecessary surgical intervention.

A new apparatus for the localization of nonpalpable mammary lesions.

A new apparatus has been used for the localization of 46 nonpalpable mammary lesions seen in either of two radiological projections. This device compresses and immobilizes the breast independently of the mammography equipment and permits a three-dimensional localization of the lesion by using the technique of X-ray angulation. The results demonstrate the efficiency of the procedure. Transfixation of the lesions was established in 30 cases (65.2%), the guidewire passed very close to the lesion in 14 cases (30.4%), and in 2 cases (4.4%) the guidewire was seen to be less than 10 mm away from the lesion. Correct preoperative localization of the lesions permitted a correct diagnosis with minimal biopsies.

A multimodality approach to the diagnosis of breast hamartomas with atypical mammographic appearance.

The ultrasonographic appearance of breast hamartomas (BHs) is described and its diagnostic utility is discussed in this study of 27 women with mammographic findings both typical and atypical of BH. The role of computed tomography (CT) in the diagnosis of BH of atypical mammographic appearance is also analyzed. These 27 cases of BH were detected in women submitted to mammographic screening. Ages ranged from 45 to 65 years (mean age 52.6 years). In all cases physical and ultrasonographic examinations were carried out. CT studies were carried out in seven cases. Core biopsy was performed in 18 cases of lesions with a mammographic appearance atypical of BH. Lesions were palpable in 9 cases and nonpalpable in 18. Mammographic appearance was characteristic in nine cases. In 19 cases a hypoechoic solid mass with hyperechoic lines and/or bands was seen. This ultrasonographic image is suspicious of BH. Finally, both CT and core biopsy findings were of great help in the diagnosis of BH in the cases where mammographic and ultrasonographic studies were inconclusive. We consider that a combination of mammography, ultrasonography, CT, and core biopsy is fundamental for the successful diagnosis of breast hamartomas not seen in typical form in mammograms.
