Improved survival in cancer of the colon and rectum in Sweden.

AIMS: To analyse time-trends in survival of patients with colon and rectal cancer in Sweden. PATIENTS AND METHODS: Data including all patients diagnosed with adenocarcinoma of the colon and rectum between 1960 and 1999, from the Swedish Cancer Registry, were analysed. The observed and relative survival rates were calculated according to the Hakulinen cohort method. RESULTS: Five-year relative survival rate for cancer of the colon improved significantly from 39.6% in 1960--1964 to 57.2% in 1995--1999 and for rectal cancer from 36.1 to 57.6%, respectively. Corresponding observed survival improved from 31.2 to 44.3% for colon cancer and from 28.4 to 45.4% for rectal cancer. The largest improvement of survival were seen during the later part of the period observed. CONCLUSION: The survival of patients with colon and rectal cancer in Sweden continues to improve, especially in rectal cancer, which now has a 5-year observed and relative survival rate comparable to that for colon cancer. The survival improvement in rectal cancer is probably a result of the implementation of total mesorectal excision and pre-operative radiotherapy.

Acute pancreatitis: a prospective study of its incidence, aetiology, severity, and mortality in Iceland.

OBJECTIVE: To evaluate the incidence, aetiology, severity and mortality of patients with acute pancreatitis. DESIGN: Prospective study. SETTING: University hospital, Iceland. PATIENTS AND METHODS: All 50 patients diagnosed with acute pancreatitis during the one-year period October 1998-September 1999 inclusive. MAIN OUTCOME MEASURES: APACHE II, and Ranson and Imrie scores, and C-reactive protein (CRP) concentrations. The Balthazar-Ranson criteria were used for scoring of computed tomograms (CT). RESULTS: 27 of the 50 patients were male. The median age of the whole series was 60 years (range 19-85). The estimated incidence was 32/100000 for the first attack of acute pancreatitis. The causes were; gallstones 21 (42%), alcohol 16 (32%), miscellaneous 12 (24%), and idiopathic 1 (2%). 15 (33%) of the patients had APACHE II scores > or = 9, 17 (38%) had Ranson scores of > or = 3, 23 (50%) had Imrie scores of > or = 3, and 16 (34%) had CRP concentrations over 210 mg/L during the first 4 days or > 120 mg/L during the first week. Seven patients had severe pancreatitis. 2 patients in the whole group died, and both had clinically severe pancreatitis. CONCLUSIONS: This study indicates that the incidence of less severe acute pancreatitis is rising. Prospective assessment makes it possible to evaluate the aetiological factors more accurately. Measurement of the CRP concentration is an attractive and simple alternative to the severity scoring systems currently in use.

Metanephric adenoma.

A 59-year old woman was diagnosed with a tumour in her right kidney. A nephrectomy was performed, and a 45 mm diameter tan-pink coloured tumour was found. Microscopy revealed small, dark cells in organized arrays of small round acini and tubules with glomeruloid infoldings. A diagnosis of metanephric adenoma was made. The tumour cells proved diploid on flow cytometry and immunohistochemical staining was positive for CAM 5.2 and AE-3. FISH analysis of three chromosomes did not reveal any abnormal karyotype. It is important to differentiate metanephric adenoma from renal cell carcinoma and adult Wilm's tumour, since it has a benign course.

Pyomyositis due to non-haemolytic streptococci.

We present a unique case of a multifocal non-tropical pyomyositis due to non-haemolytic streptococci in a 36-y-old woman. The initial infection was in an area of contused muscle in the left anterior thigh and spread to the contralateral femoral and gluteal musculature. There was a previous history of Staphylococcus aureus pyomyositis and colitis ulcerosa. The patient was treated successfully with surgical drainage and parenteral antibiotics.

Kingella kingae infections in paediatric patients: 5 cases of septic arthritis, osteomyelitis and bacteraemia.

Kingella kingae is a Gram-negative rod most often recognized as 1 of the organisms causing septic arthritis and osteomyelitis in children. Infection caused by K. kingae had not been diagnosed in Iceland until 5 cases were diagnosed at the Paediatric Department at the University Hospital of Iceland over a 1 year period. In this report we describe these 5 children with invasive infection caused by K. kingae (2 with septic arthritis, 1 with osteomyelitis, 1 with septic arthritis and osteomyelitis, and 1 with bacteraemia) and review the literature. All bacterial isolates were identified by the Bactec culture system.

[The effect of pregnancy on the survival of women diagnosed with breast cancer.].

OBJECTIVE: To answer the question whether the prognosis of women with breast cancer is affected by pregnancy after diagnosis. MATERIAL AND METHODS: We used information from the Icelandic Cancer Registry, the Birth Registry and the Genetic Committee. We identified all women who were diagnosed with breast cancer in the years 1927-1992 and who later became pregnant. Controls were women without a history of childbirth after diagnosis of breast cancer. They were matched on tumour size, axillary lymph node status and years of birth and diagnosis, with four year deviation. RESULTS: In the years 1927-1992, 838 women at ages below 50 were diagnosed with breast cancer in Iceland. Of those, 29 gave birth to a child after the diagnosis. Fourteen cases and 33 matched controls fulfilled the inclusion criteria of the study. Survival was better in the group of women who became pregnant after diagnosis, but the difference was not statistically significant (P=0.06). DISCUSSION: Our results do not indicate that the prognosis of women who become pregnant after the diagnosis of breast cancer is worse than of those who do not become pregnant. The group was too small to make definite conclusions. However, the results are in concordance with results from other studies.

[Kingella kingae ostemyelitis and septic arthritis in paediatric patients. Six cases from the Department of Pediatrics, National University Hospital of Iceland.].

Kingella kingae (K. kingae) is a gram negative rod most often associated with septic arthritis and osteomyelitis in children. Infections caused by K. kingae had not been reported in Iceland when six cases were diagnosed at the Pediatric Department at the National University Hospital of Iceland. In this report we describe those cases and review the literature.
