Poverty and resistance to family planning

Nonacceptors of family planning in the area covered by the Government Maternity Hospital, Hyderabad, Andhra Pradesh, India, were analyzed. Among the 3901 eligible couples in the area, 3314 (85%) were nonacceptors. Among those with fewer than 2 children, more than 93% were nonacceptros; among those with 3, 84%; among those with 4 or 5 children, 71%. Even after 6 children 69% refused contraception. Most were poor, illiterate, and were either ignorant of any method or had doubts about the method. These people dream of 2 meals a day and live in unsanitary conditions. If a child is born, there is no guarantee it will live. In such situations, an extra child makes little difference in living conditions and after 3 or 4 years can actually make a contribution to the family. To get more nonacceptors to increase their interest in smaller families, basic changes must be made in economic conditions, education, health care, and old age insurance and pensions. Until a certain threshold level of social and economic development is reached, there will not be a sustained drop in the birthrate.     

A prognostic system applicable to patients with resectable liver metastasis from colorectal carcinoma staged by positron emission tomography with [18F]fluoro-2-deoxy-D-glucose: role of primary tumor variables

BACKGROUND: The purpose of this study was to develop a prognostic system applicable to patients with hepatic metastasis from colorectal cancer in whom extrahepatic disease was excluded by preoperative PET with [(18)F]fluoro-2-deoxy-D-glucose (FDG-PET). Data from two institutions were analyzed separately and together to improve general applicability of results. STUDY DESIGN: Data were analyzed for 285 consecutive patients undergoing liver resection for colorectal metastases from 1995 to 2005 at 2 institutions routinely using preoperative FDG-PET with. Fifteen clinicopathologic variables of the primary and secondary tumors were examined to identify factors predictive of survival. RESULTS: Outcomes were correlated with poorly differentiated tumor grade in both data sets. Because patients with poorly differentiated tumors comprised a small proportion (16%) of the population, patients with well-differentiated or moderately differentiated tumors were analyzed independently. In this subgroup, positive lymph node status in the primary colorectal tumor resection specimen was the only characteristic that predicted survival of patients in both institutions. Consequently, patients were sorted into three prognostic categories: poor tumor differentiation; well-differentiated or moderately differentiated tumors and node positive; and well-differentiated or moderately differentiated tumors and node negative. These groups had significantly different overall survival on Kaplan-Meier analysis (p=0.0014). CONCLUSIONS: In patients with colorectal liver metastases staged with FDG-PET with overall survival can be predicted directly from data in the pathology report of the colorectal primary tumor. This study also indicates the need for new molecular tumor markers of prognosis to complement clinicopathologic markers if the goal of prediction of outcomes in individual patients is to be reached.     

Use of percutaneous drainage to treat hepatic abscess after radiofrequency ablation of metastatic pancreatic adenocarcinoma

Radiofrequency ablation (RFA) is well described in the treatment of primary hepatic malignancies and colorectal carcinoma hepatic metastases. A known complication of RFA is the development of hepatic abscess. The management of hepatic abscesses subsequent to RFA for metastatic disease is not well described. A 49-year-old female with pancreatic adenocarcinoma underwent pancreaticoduodenectomy followed by adjuvant chemoradiation. Following 6 months' treatment, a new liver metastasis was identified. It remained stable for 6 months during additional chemotherapy and thereafter was treated with RFA. Three weeks after RFA, the patient presented with malaise and leukocytosis, and a CT scan demonstrated a large hepatic abscess at the site of the RFA. She remained febrile despite needle aspiration and intravenous antibiotics. A percutaneous drain was placed and the symptoms resolved. Contrast injection of the drain 4 weeks later demonstrated resolution of the abscess cavity but communication with the biliary tree. The drain was removed and the tract embolized with Gel-foam to prevent complications of biliary-cutaneous fistula. She remains well without evidence of abscess or disease recurrence. Thus, RFA can be used in treatment of limited isolated hepatic metastases from previously treated pancreatic adenocarcinoma. However, the incidence of hepatic abscess is increased due to bilioenteric anastomosis; extended antibiotic prophylaxis should be considered.     

Altered ATP-dependent mitochondrial Ca2+ uptake in cold ischemia is attenuated by ruthenium red

BACKGROUND: Graft dysfunction as a result of preservation injury remains a major clinical problem in liver transplantation. This is related in part to accumulation of mitochondrial calcium (Ca(2+)), which has been linked to activation of proapoptotic factors. We hypothesized that cold ischemia increases mitochondrial Ca(2+) uptake in a concentration dependent fashion and that ruthenium red (RR) will attenuate these changes by inhibiting the mitochondrial Ca(2+) uniporter. METHODS: Rat livers perfused with cold University of Wisconsin (UW) solution (4 degrees C) with or without RR (10 microM) via the portal vein (n = 3 per group) were processed immediately (no ischemia) or after 24 h cold-storage (24 h cold ischemia). Mitochondria were separated by differential centrifugation, and adenosine triphosphate (ATP)-dependent (45)Ca(2+) uptake was determined in the presence of ATP (5 mM), adenosine diphosphate (ADP), or adenosine 5'-beta,gamma-imidotriphosphate (AMP-PNP); variable concentrations of extramitochondrial (45)Ca(2+) were used. All measurements were performed in triplicate. Student's t test with P < 0.05 was taken as significant. RESULTS: Our data demonstrate the following: 1) ATP-dependent (45)Ca(2+) uptake in mitochondria separated from livers following 24 h of cold ischemia in UW alone was higher than in mitochondria isolated from non-ischemic livers; the increased uptake was dependent on the concentration of (45)Ca(2+) in the incubation buffer. 2) There was no difference in ATP-dependent (45)Ca(2+) uptake between nonischemic mitochondria and those separated from livers stored in UW-RR for 24 h. 3) (45)Ca(2+) uptake in mitochondria from livers subjected to 24 h of cold ischemia in UW-RR was significantly lower compared to those from livers stored in UW alone when (45)Ca(2+) concentrations were greater than 1 microM. CONCLUSION: 1) Cold ischemia affects mitochondrial Ca(2+) handling, especially when it is challenged by high extramitochondrial Ca(2+) concentrations. 2) The addition of RR in preservation solution attenuates the effects of cold ischemia on mitochondrial Ca(2+) handling. 3) Inhibition of mitochondrial Ca(2+) uniporter with RR protects mitochondria from Ca(2+) overload at high Ca(2+) concentrations. These findings may offer a potentially effective strategy for prevention of ischemia-reperfusion injury in liver transplantation.     

Quantification of prostate shrinkage after microwave thermotherapy: a comparison of calculated cell-kill versus 3D transrectal ultrasound planimetry

PURPOSE: To compare prostate shrinkage after transurethral microwave thermotherapy (TUMT) with calculated cell-kill. MATERIALS AND METHODS: The calculated cell-kill from 33 males with benign prostatic hyperplasia (BPH) treated with TUMT according to the ProstaLund Feedback Treatment (PLFT) method was compared to the post-treatment prostate volume change. The prostate volume was estimated with three-dimensional transrectal ultrasound (3D-TRUS) planimetry at baseline, 3, 6, and 12 months follow-up. A paired t-test was used to test the statistical significance of differences between the cell-kill volume and the prostate volume change. Linear regression was used to infer a relationship between the cell-kill and the 3D-TRUS data. The reproducibility of the 3D-TRUS method was assessed in repeated measurements. RESULTS: The mean prostate volume at baseline (N=33) was 56.1cm(3). After 3 (N=25), 6 (N=29) and 12 months (N=23), it was 45.5 cm(3), 39.7 cm(3), and 45.1cm(3), respectively. The corresponding average cell-kill volume was 16.4 cm(3), 17.1cm(3), and 17.2 cm(3), respectively. Predicted cell-kill volume was significantly larger than prostate shrinkage at 3 (p<0.0001), 6 (p=0.0002), and 12 months (p<0.0001), and showed a strong correlation at 3 and 6 months (r=0.74, p<0.0001). Correlation at 12 months was moderate (r=0.57, p=0.0041). Examination and investigation variability both averaged 2.5%. CONCLUSIONS: Cell-kill calculations of the PLFT method are proportional to the 3D-TRUS prostate shrinkage by a factor of 0.5 and have a precision of approximately +/-10 cm(3) for 90% of the patients during the first year after treatment.     

Idiopathic chronic pancreatitis with periductal lymphoplasmacytic infiltration: clinicopathologic features of 35 cases

To clarify clinicopathologic features of idiopathic chronic pancreatitis with lymphoplasmacytic infiltration, we carried out a study of 35 cases. There were two histologic groups, which we have designated lymphoplasmacytic sclerosing pancreatitis and idiopathic duct-centric chronic pancreatitis. Lymphoplasmacytic sclerosing pancreatitis (22 cases) was a fibrosing process with diffuse lymphoplasmacytic infiltrates involving pancreatic lobules and ducts, adipose tissue, blood vessels, and common bile duct. Obliterative phlebitis was found in every case except for one. The histologic features were similar to other idiopathic fibrosclerosing disorders, and one patient also had retroperitoneal fibrosis. Affected patients tended to be elderly men. Idiopathic duct-centric chronic pancreatitis (13 cases) was characterized by inflammatory infiltrates (including neutrophils) that were denser in the lobules than in interlobular fibrotic areas. Neutrophils were also prominent in the ducts, and destruction of the duct epithelium was commonly seen. Patient ages were more broadly distributed than in lymphoplasmacytic sclerosing pancreatitis. Two patients had inflammatory bowel disease. We conclude that idiopathic chronic pancreatitis with lymphoplasmacytic infiltration, sometimes called autoimmune pancreatitis, consists of at least two different processes. One of these, lymphoplasmacytic sclerosing pancreatitis, is a histologically unique lesion and could be a pancreatic manifestation of idiopathic fibrosclerosing disorders.

Acute pancreatitis in patients with Crohn's disease: clinical features and outcomes

BACKGROUND: Acute pancreatitis has occasionally been associated with Crohn's disease (CD), but whether a causal association exists remains unclear. We sought to determine the frequency of etiologies in a consecutive series of patients with CD with acute pancreatitis. METHODS: A centralized diagnostic index was used to identify all patients with CD with acute pancreatitis that were evaluated at Mayo Clinic Rochester between 1976 and 2001. Both diagnoses were made or confirmed at our institution. Records were abstracted for demographics, presenting symptoms, diagnostic tests, risk factors of pancreatitis, treatment, and follow-up. RESULTS: Forty-eight patients with CD with pancreatitis were identified. The median age at diagnosis of acute pancreatitis was 47 years (range, 31-91 yr). Forty-six (96%) met biochemical criteria for acute pancreatitis. The most sensitive radiographic tests were abdominal computed tomography (70%) and abdominal ultrasound (46%). The etiology of pancreatitis was considered to be gallstones (21%), significant alcohol intake (15%), use of purine analogs (13%), duodenal Crohn's involvement (12%), postendoscopic retrograde cholangiopancreatography complications (10%), postoperative complications (12%), use of other medications (4%) and idiopathic (8%). The median length of hospitalization was 7 days (range, 0-40 d). Ten patients (21%) had recurrence of acute pancreatitis. Three patients (6%) were subsequently diagnosed with pancreatic cancer. CONCLUSIONS: A definite etiology could be identified in most patients with CD with acute pancreatitis. Gallstones and alcohol accounted for more than one third of cases, whereas CD, either because of duodenal involvement or medications used for its treatment, accounted for more than one quarter of the cases. A small proportion of patients remained idiopathic.
