[Evisceration of the small intestine due to rectum rupture].

Evisceration of the small intestine from the anus due to a rectal rupture was diagnosed in two patients, males aged 93 and 25 years. The former had had a rectal prolapse for years; the evisceration occurred after a fall from the bed. The lower abdomen of the second patient was caught between the counterweight of a bridge and a wall. Laparotomy in both patients revealed a rupture in the ventral portion of the rectosigmoid, but no pre-existent lesions in this part of the intestinal wall. Treatment in the first patient consisted of resection of the rectosigmoid with creation of an end colostomy, the eviscerated intestinal tract being repositioned in the abdominal cavity after thorough cleansing. In the second patient the eviscerated intestinal tract had to be resected. In this case also, an end colostomy was created and the rupture in the rectum was closed transanally. Both patients recovered well.

Salmonella panama osteomyelitis in an otherwise healthy patient. A case report.

A 22-year-old man had Salmonella panama osteomyelitis of the left distal tibia. He had endured a period of untreated diarrhea without fever 6 years before. The osteomyelitis was treated successfully with surgical debridement followed by 9 weeks of oral cotrimoxazole 960 mg twice daily. Salmonella osteomyelitis is rare. Most cases occur in patients with sickle cell anemia. Other conditions of local or generalized immunosuppression are also risk factors, but none were established in this patient, nor was he a chronic carrier. In reviewing the literature, no case of Salmonella panama osteomyelitis in an otherwise healthy patient was found. Although the osteomyelitis in this patient was possibly secondary to Salmonella enteritis 6 years before, the authors believe that enteric Salmonella infections should not be treated with antibiotics unless the infection is accompanied by systemic symptoms. Otherwise, the risk of chronic carriership is substantially increased. In case of Salmonella panama osteomyelitis, surgical debridement is recommended as the main component of treatment, followed by a prolonged period of specific antibiotic therapy.

[Merkel cell carcinoma: a treacherous skin tumor].

Merkel cell carcinoma is a rare malignancy of the skin in predominantly elderly patients, frequently missed because of its inconspicuous aspect. The histological diagnosis is not always easily made. Four case histories are presented. Literature shows the aggressive biological behaviour of this tumour: the rate of local recurrence is 40%, of regional metastatic disease over 50%, while approximately half the patients with a Merkel cell carcinoma will die of this skin tumour.

The plunging ranula. Pathogenesis, diagnosis and management.

Ranulas are cysts resulting from retention, or extravasation of saliva from the sublingual gland. Two varieties are described: a superficial or oral ranula and a cervical or plunging ranula. The plunging ranula is located below the mylohyoid muscle and may present as a swelling in the upper part of the neck. Four cases are described to illustrate that this condition can be the cause of a neck swelling. Aetiology, differential diagnosis and surgical management are also discussed. Recurrences are mainly due to unfamiliarity with this phenomenon and ignorance of its aetiology. Successful treatment of the plunging ranula consists of excision of the ipsilateral sublingual salivary gland, which is the source of this disorder, and intra-oral evacuation of the pseudocyst of the neck swelling. There is no need for an extensive neck dissection of the cervical extension.

Saccular intrahepatic artery aneurysm.

A patient is presented with a bleeding intrahepatic artery saccular aneurysm. The patient had for years complained of intermittent abdominal pain and was admitted with acute colicky pain in the left upper abdomen, followed by acute severe anemia. She survived after ligation of the right hepatic artery and partial resection of the right liver lobe. The postoperative course was uneventful. These lesions are rare and the diagnosis and best methods of treatment are complicated. The classic triad-pain, obstructive jaundice and bleeding-occurs only in 33 percent of cases and is in general caused by trauma. Bleeding intrahepatic saccular aneurysms cause pain and anemia as primary symptoms. The success rate of operation is still low. A possible alternative to surgery is given by selective trans-catheter embolization.
