[Laparoscopic Gastrectomy for Gastric Cancer with Adachi Type â ¥ Vascular Anomaly-A Case Report].

We report a case of laparoscopic gastrectomy for gastric cancer with an anomalous celiac trunk categorized as Type Ⅵ- Group 24 in the Adachi classification. Upper gastrointestinal endoscopy in an 81-year-old male revealed a shallow depressed lesion in the middle of the gastric body. Close examination led to diagnosis of cT1bN0M0, cStage Ⅰ gastric cancer, and laparoscopic distal gastrectomy was planned. Contrast-enhanced CT revealed no anomalous bifurcation of the hepatic artery, but the common hepatic artery ran on the dorsal side of the portal vein, branching from the superior mesenteric artery. Therefore, an Adachi Type Ⅵ-Group 24 celiac trunk anomaly was diagnosed. During surgery, the common hepatic artery could not be confirmed in guiding suprapancreatic lymph node dissection, and the portal vein was exposed. Anterior to the portal vein, nerves that are usually around the common hepatic artery continuously ran toward the hepatoduodenal ligament instead. Suprapancreatic lymph nodes were dissected, with the portal vein considered as the common hepatic artery. Adachi Type Ⅵ is a rare anomaly with an incidence of about 2%. Preoperative diagnosis enables safe and appropriate lymph node dissection.

Exploring roles and capacity development of village midwives in Sudanese communities.

INTRODUCTION: Home birth remains a strong preference and village midwives are the only option for maternal and neonatal care for many rural women in Sudan. This study assessed whether interventions such as strengthening linkages among health facility/staff, skilled birth attendants and village midwives (VMWs); strengthening the supervision system; and strengthening the governance capacity of local health departments improved their service delivery, and it examined factors linked with improved performance of VMWs in their communities. METHODS: This descriptive study comprised a cross-sectional baseline survey, two intervention years and an endline survey. Data collection involved in-depth, semi-structured questionnaire interviews. Fifty-seven VMWs and 151 community women were targeted for the study in Sinnar, a south-eastern state of Sudan. Participants were interviewed about demographic information, perceptions of operational barriers, training provided, function in the community, supervision and referral for emergency cases. RESULTS: Results showed the monthly average number of VMW-assisted home births increased from 1.4 at the baseline survey in October 2011 to 3.3 at the endline survey in October 2013. The annual average number of emergency cases referred by VMWs increased from 1.6 to 3.5, and the percentage of VMWs using official monthly reports increased from 33% to 80%. VMWs reported improved bonds with their supervisors and relationships in the community. CONCLUSION: Improved service provision may be associated with development of supervision systems for VMWs, active provision of community activities, strengthened linkages between health facilities and VMWs and enhanced community trust of VMWs. Given issues such as shortages and poor retention of human resources for maternal and newborn health service delivery in particular settings, international communities should focus on strengthening capacity of community midwives for home births as a realistic measure.

Role of family medicine physicians in providing nutrition support to older patients admitted to orthopedics departments: a grounded theory approach.

BACKGROUND: Care of older adults requires comprehensive management and control of systemic diseases, which can be effectively managed by family physicians. Complicated medical conditions in older patients admitted to orthopedic departments (orthopedic patients) necessitate interprofessional collaboration. Nutrition is one of the essential components of management involved in improving the systemic condition of older patients. Nutrition support teams play an important role in nutrition management and can be supported by family physicians. However, the role of family physicians in nutrition support teams is not well documented. This study aimed to investigate the role of family physicians in supporting nutrition management in orthopedic patients. METHODS: This qualitative study was conducted between January and June 2023 using constructivist grounded theory methodology. Eight family medicine physicians, three orthopedic surgeons, two nurses, two pharmacists, four rehabilitation therapists, four nutritionists, and one laboratory technician working in Japanese rural hospitals participated in the research. Data collection was performed through ethnography and semi-structured interviews. The analysis was performed iteratively during the study. RESULTS: Using a grounded theory approach, four theories were developed regarding family physicians' role in providing nutrition support to orthopedic patients: hierarchical and relational limitation, delay of onset and detection of the need for geriatric care in orthopedic patients, providing effective family medicine in hospitals, and comprehensive management through the nutrition support team. CONCLUSIONS: The inclusion of family physicians in nutrition support teams can help with early detection of the rapid deterioration of orthopedic patients' conditions, and comprehensive management can be provided by nutrition support teams. In rural primary care settings, family physicians play a vital role in providing geriatric care in community hospitals in collaboration with specialists. Family medicine in hospitals should be investigated in other settings for better geriatric care and to drive mutual learning among healthcare professionals.

Imported Hepatitis E Virus Genotype 1: A Rare Case of Acute Hepatitis Managed with Steroid Pulse Therapy.

A 26-year-old Indian man who had arrived in Japan 24 days prior presented to our hospital with abdominal pain and a fever. A blood test revealed marked hepatic dysfunction, and imaging tests confirmed a diagnosis of acute hepatitis. The patient's liver function and coagulability deteriorated, and his general condition was poor. Given the possibility of fulminant hepatic failure, we initiated steroid pulse therapy. Following the initiation of steroid therapy, the patient's liver function and subjective symptoms rapidly improved. Testing revealed positive findings for IgA-hepatitis E virus, and a genetic analysis of hepatitis E identified genotype 1, which is not endemic to Japan, leading to a definitive diagnosis of imported hepatitis E infection from India. The successful response to steroid therapy highlights the potential benefit of this approach in managing severe cases of acute hepatitis E, a rare occurrence in Japan. This case underscores the importance of considering hepatitis E infection in individuals with a recent travel history to regions with high prevalence and the potential benefits of steroid therapy in managing severe cases of acute hepatitis E.

AlveoMPU: Bridging the Gap in Lung Model Interactions Using a Novel Alveolar Bilayer Film.

The alveoli, critical sites for gas exchange in the lungs, comprise alveolar epithelial cells and pulmonary capillary endothelial cells. Traditional experimental models rely on porous polyethylene terephthalate or polycarbonate membranes, which restrict direct cell-to-cell contact. To address this limitation, we developed AlveoMPU, a new foam-based mortar-like polyurethane-formed alveolar model that facilitates direct cell-cell interactions. AlveoMPU features a unique anisotropic mortar-shaped configuration with larger pores at the top and smaller pores at the bottom, allowing the alveolar epithelial cells to gradually extend toward the bottom. The underside of the film is remarkably thin, enabling seeded pulmonary microvascular endothelial cells to interact with alveolar epithelial cells. Using AlveoMPU, it is possible to construct a bilayer structure mimicking the alveoli, potentially serving as a model that accurately simulates the actual alveoli. This innovative model can be utilized as a drug-screening tool for measuring transepithelial electrical resistance, assessing substance permeability, observing cytokine secretion during inflammation, and evaluating drug efficacy and pharmacokinetics.

Primary Peritonitis due to Group A Streptococcus Successfully Treated with Intraperitoneal Drainage.

A 42-year-old woman was admitted to our hospital because of lower abdominal pain and diarrhea. Although the initial symptoms and imaging findings were similar to those of acute enteritis, blood and ascites cultures led to the diagnosis of primary peritonitis caused by group A Streptococcus. In many cases, the disease rapidly deteriorates, and laparotomy is performed for the early diagnosis and to reduce the number of bacteria in the abdominal cavity. In the present case, intraperitoneal drainage was effective for avoiding surgery. We suggest that intraperitoneal drainage is effective for the treatment of this disease.

Pharmacokinetics and pharmacodynamics of insulin aspart in patients with type 2 diabetes: assessment using a meal tolerance test under clinical conditions.

1. Few studies have evaluated the pharmacokinetics of rapid-acting insulin analogues in patients with Type 2 diabetes, especially under clinical conditions. The aim of the present study was to assess both the pharmacokinetics and pharmacodynamics of insulin aspart in Type 2 diabetic patients who were being treated with the analogue alone. 2. Meal tolerance tests with and without self-injection of a customary dose of insulin aspart (0.05-0.22 U/kg) were conducted in 20 patients in a randomized cross-over study. 3. The dose of insulin aspart (per bodyweight) was significantly correlated with both the maximum concentration (r(2) = 0.59; P < 0.01) and area under the concentration-time curve for insulin aspart (r(2) = 0.53; P < 0.01). However, the time to maximum concentration (T(max)), which varied widely from < 60 to ≥ 120 min, was not associated with either dosage (r(2) = 0.02; P = 0.51) or body mass index (r(2) = 0.02; P = 0.57). Injection of insulin aspart exacerbated delayed hyperinsulinaemia after meal loading, mainly in patients with T(max) ≥ 120 min. With regard to pharmacodynamics, insulin aspart had favourable effects on postprandial hyperglycaemia, hyperglucagonaemia and hyperlipidaemia. 4. The T(max) for this insulin analogue differed greatly between individuals and delayed hyperinsulinaemia was particularly exacerbated in patients with higher T(max) values. Identification of the factors contributing to interindividual variation in the absorption lag time is essential for improving the efficacy and safety of insulin aspart.

Real-world safety and effectiveness of pembrolizumab in Japanese patients with radically unresectable melanoma: An all-case postmarketing surveillance in Japan.

This all-case postmarketing surveillance (PMS) survey (101 centers; February 15, 2017, to March 3, 2020) captured factors that impact the safety and effectiveness of newly initiated pembrolizumab monotherapy for the treatment of radically unresectable melanoma in Japan. Eligible patients were enrolled both retrospectively and prospectively, and followed up at 1, 3, 6, and 12 months. Safety assessments included treatment-related adverse events (TRAEs), adverse events of special interest (AEOSIs) from the Japanese Risk Management Plan (J-AEOSIs), and J-AEOSIs related to pembrolizumab. Effectiveness assessments included objective response rate (ORR; complete response/partial response) and disease control rate (DCR) according to the RECIST criteria. Overall, 294 and 236 patients comprised the safety and effectiveness (RECIST) assessment sets, respectively. Median (range) age of the patients was 70 (22-94) years, and the majority (60.4%) received pembrolizumab as first-line therapy. The most common type of melanoma was cutaneous (41.5%), followed by mucosal (29.3%), acral (24.8%), and unknown (4.4%). Overall, 45.2% and 24.8% of patients experienced TRAEs and AEOSIs, respectively. In total, 24.8% and 9.2% of patients experienced any-grade and grade ≥3 pembrolizumab-related AEOSIs, respectively. The most common grade ≥3 pembrolizumab-related AEOSIs were endocrine disorders and liver dysfunction (2.4% each), followed by colitis/severe diarrhea (2.0%), interstitial lung disease (1%), and type 1 diabetes (0.7%). No grade 5 J-AEOSIs were observed. ORR was 16.5% at the 1-year follow-up: mucosal melanoma (20%), acral melanoma (10%), and cutaneous melanoma (17.5%). ORR was higher among patients who did not receive versus those who did receive previous systemic therapy across all three melanoma types. DCR was 52.1% at the 1-year follow-up: cutaneous melanoma (57.3%), acral melanoma (51.7%), and mucosal melanoma (43.1%). This all-case PMS survey confirmed the real-world safety and effectiveness of pembrolizumab monotherapy for the treatment of radically unresectable melanoma in Japan.

Clinicopathological features of PD-L1 protein expression, EBV positivity, and MSI status in patients with advanced gastric and esophagogastric junction adenocarcinoma in Japan.

This real-world study examined the prevalence of programmed death ligand-1 (PD-L1) expression and assessed the frequency of microsatellite instability-high (MSI-H) status and Epstein-Barr virus (EBV) positivity in Japanese patients with advanced gastric and gastroesophageal junction (GEJ) adenocarcinoma. This multicenter (5 sites), retrospective, observational study (November 2018-March 2019) evaluated Japanese patients with advanced gastric and GEJ adenocarcinoma after surgical resection (Stage II/III at initial diagnosis) or unresectable advanced cancer (Stage IV). The primary objectives were prevalence of PD-L1 expression (combined positive score [CPS] ≥1), MSI status, and EBV positivity. Tumor specimens of 389/391 patients were analyzed (male, 67.1%; mean age, 67.6 ± 12.2 years); 241/389 (62%) were PD-L1 positive, 24/379 (6.3%) had MSI-H tumors, and 13/389 (3.3%) were EBV positive. PD-L1 expression was higher in tumor-infiltrating immune cells than in tumor cells for lower CPS cutoffs. Among patients with MSI-H tumors and EBV-positive tumors, 19/24 (79.2%) and 9/13 (69.2%), respectively, were PD-L1 positive. A greater proportion of patients with MSI-H tumors (83.3% [20/24]) were PD-L1 positive than those with MSI-low/stable tumors (60.8% [216/355]; p = .0297); similarly, an association was observed between history of H pylori infection and PD-L1 expression. A higher proportion of patients with MSI-H tumors demonstrated PD-L1 expression with a CPS ≥10 (66.7% [16/24]) vs those with MSI-low/stable tumors (24.8% [88/355]; p < .0001). The prevalence of PD-L1 positivity among Japanese patients was comparable to that in previous pembrolizumab clinical trials and studies in gastric cancer. Particularly, higher PD-L1 expression was observed in MSI-H tumors.

The Contribution of Temporal Flat Lateral Position on the Mortality and Discharge Rates of Older Patients with Severe Dysphagia.

Severe dysphagia leads to mortality in older patients and hinders their discharge from hospitals. The temporal flat lateral position (TFLP) enables them to continuously eat, thus resolving the aforementioned issues. We aimed to explore the effect of TFLP on the mortality and discharge rates of older patients with severe dysphagia. This interventional study comprised a historical control of patients admitted to a rural community hospital from January 2019 to December 2020 and diagnosed with severe dysphagia. The primary outcomes included the mortality and the rate of discharge from the hospital. While the intervention group was treated with TFLP, the control group underwent no treatment. We selected 79 participants (intervention group = 26, control group = 53), with an average age of 87.9 years. The discharge rate was significantly higher in the intervention group than in the control group (57.7% vs. 26.4%, p = 0.012). The mortality rate was also significantly lower in the intervention group compared to the control group (34.6% vs. 71.7%, p = 0.003). TFLP can improve the discharge and mortality rates in community hospitals, thereby improving patient outcomes. Clinicians should focus on practical education and the implementation of TFLP in communities in order to promote it.

Inflammatory Pseudo-tumor of the Liver Accompanied by Eosinophilia.

A 28-year-old woman was referred to our hospital for liver dysfunction and neck pain. Blood tests revealed elevated liver enzymes and eosinophilia. Ultrasonography, computed tomography, and magnetic resonance imaging showed a mass lesion near the hepatic hilus. The tumor was considered to be an inflammatory pseudo-tumor or malignancy. A liver-mass biopsy was performed and led to a diagnosis of inflammatory pseudo-tumor. In the present case, a markedly elevated eosinophil count was a characteristic clinical feature, and the patient underwent steroid therapy. Treatment resulted in a reduced eosinophil count, improved neck symptoms, and disappearance of the inflammatory pseudo-tumor.

Late-onset type-2 autoimmune pancreatitis with two mass lesions diagnosed by endoscopic ultrasound-guided fine-needle aspiration.

A 65-year-old man with ulcerative colitis presented with aggravated diabetes. Computed tomography showed two masses in the body and tail of the pancreas. Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) was performed, with histopathological findings suggesting autoimmune pancreatitis (AIP). Type-2 AIP was suspected, and administration of prednisolone was initiated. The pancreatic masses had disappeared after the treatment. In this case, EUS-FNA was effective for the diagnosis of type-2 AIP. The two-lesion mass formation observed here is a rare presentation of the disease. In patients with a history of ulcerative colitis, the possibility of late-onset type-2 AIP should be kept in mind.

Cholecystitis with abdominal wall biloma after percutaneous transhepatic gallbladder aspiration: A case report.

BACKGROUND: Abdominal wall biloma is an uncommon entity. We herein report an extremely rare case of cholecystitis with abdominal wall biloma after percutaneous transhepatic gallbladder aspiration (PTGBA). PRESENTATION OF CASE: A 69-year-old woman was diagnosed with acute cholecystitis, and PTGBA was performed on Day 1. PTGBA was performed a second time because of re-expansion of the gallbladder and an increased CRP level on Day 3. Computed tomography was performed on Day 9 because we suspected recurrence of cholecystitis. It revealed a well-circumscribed fluid collection between the abdominal wall or the diaphragm and the liver. Based on these intraoperative findings, we diagnosed her with cholecystitis with abdominal wall biloma. Cholecystectomy and drainage of the abdominal wall biloma were performed on Day 10. The postoperative course was uneventful, and she was discharged on Day 18. DISCUSSION: Early cholecystectomy is the gold-standard treatment for acute cholecystitis, but cholecystectomy is not performed in some cases. PTGBA is much more convenient, quicker, and less costly, but inappropriate aspiration during the second PTGBA session might have spread the infected bile to the abdominal wall through the PTGBA route. CONCLUSION: This case represents the first reported case of a biloma within the abdominal wall after PTGBA. To prevent this complication, we should aspirate gallbladder bile sufficiently during PTGBA. In addition, we should consider performing alternative therapy, such as percutaneous transhepatic gallbladder drainage or an operation, when we fail to appropriately aspirate.

Characterization of developmental colony formation in Corynebacterium glutamicum.

We report that Corynebacterium glutamicum colonies exhibit a developmental transition in culture. When cultured on a routinely used complete medium (CM2B), this bacterium first formed a flat translucent colony. Subsequently, some parts of this colony expanded to form small spherical yellow colonies that finally developed into a single large yellow colony. The small flat colony consisted of long thick cells, which were occasionally V or Y shaped, while the large yellow colony consisted of short small rods. A similar colony development pattern was observed in Corynebacterium ammoniagenes and Corynebacterium callunae. Analysis following shotgun cloning revealed that the introduction of a multi-copy-number plasmid carrying amtR, a global transcriptional regulator for nitrogen metabolism, into C. glutamicum cells induced precocious colony development. An amtR-null C. glutamicum mutant exhibited delayed development. Detailed observations of C. glutamicum cells cultured on CM2B medium containing buffers at various pH values revealed that the colony growth was rapid at a pH value of 6.4 or higher and slow but distinct at a pH of less than 6.4. This pH threshold increased to 6.8 following the addition of 0.1% glucose into the medium.

Regulation of adiponectin receptor expression in human liver and a hepatocyte cell line.

Nonalcoholic fatty liver disease (NAFLD) is closely associated with obesity. An adipocyte-derived hormone, adiponectin, may play a role in the pathophysiology of NAFLD through insulin-sensitizing and antifibrotic effects. We found that hepatic expression of adiponectin receptor AdipoR2, but not AdipoR1, was down-regulated in 14 patients with NAFLD compared with 7 patients with a normal liver (P < .05). To investigate the significance of the adiponectin system in obesity and NAFLD, we examined the regulation of AdipoR2 expression in a nonmalignant human hepatocyte cell line, the THLE-5b cells. Insulin down-regulated the levels of AdipoR2 messenger RNA (mRNA) and protein, whereas an adipocytokine, tumor necrosis factor alpha, up-regulated them. A thiazolidinedione, pioglitazone, up-regulated the expression of AdipoR2 mRNA and protein in THLE-5b cells. The AdipoR2 mRNA level was decreased in fatty THLE-5b cells induced by coincubating with fatty acids. These findings suggest that down-regulation of AdipoR2 in the liver caused by hyperinsulinemia and steatosis may play a role in the development of NAFLD.

Factors associated with improvement of fasting plasma glucose level by mealtime dosing of a rapid-acting insulin analog in type 2 diabetes.

This study investigated whether strict control of plasma glucose levels with mealtime dosing of a rapid-acting insulin analog improves early morning fasting plasma glucose (FPG) levels in patients with type 2 diabetes. A rapid-acting insulin analog was administered at each mealtime to 40 Japanese patients with type 2 diabetes whose existing antidiabetic medication was discontinued. Approximately one-half (52.5%) of the patients achieved a minimum early morning FPG levels achievable (nadir FPG) of <120mg/dL with mealtime dosing of a rapid-acting insulin analog alone; no basal insulin replacement was needed in these patients. Nadir FPG levels were independent of duration of diabetes, baseline body mass index (BMI) or glycemic control. All patients who had been treated with sulfonylureas needed basal insulin replacement. Low responses of insulin to glucagon and to arginine, and high response of glucagon to arginine may explain the failure to improve FPG levels with postprandial insulin replacement alone. In conclusion, approximately one-half of the patients with type 2 diabetes achieved appropriate control of FPG by rapid-acting insulin analog monotherapy. Basal insulin secretory defects in type 2 diabetes may be estimated by the responses of insulin to glucagon and to arginine and the response of glucagon to arginine. This study contributes to a better understanding of the pathophysiology contributing to the heterogeneity in the characteristics of insulin secretion in type 2 diabetes.

Tumor necrosis factor-alpha-induced production of plasminogen activator inhibitor 1 and its regulation by pioglitazone and cerivastatin in a nonmalignant human hepatocyte cell line.

Plasminogen activator inhibitor 1 (PAI-1) is an important mediator of atherosclerosis and liver fibrosis in insulin resistance. Circulating levels of PAI-1 are elevated in obese individuals, and PAI-1 messenger RNA is significantly higher in the livers of obese type 2 diabetic individuals than in nonobese type 2 diabetic individuals. To address the mechanism underlying the up-regulation of hepatic PAI-1 in obesity, we tested the effects of tumor necrosis factor alpha (TNF-alpha), an important link between obesity and insulin resistance, on PAI-1 production in the nonmalignant human hepatocyte cell line, THLE-5b. Incubation of THLE-5b cells with TNF-alpha stimulated PAI-1 production via protein kinase C-, mitogen-activated protein kinase-, protein tyrosine kinase-, and nuclear factor-kappaB-dependent pathways. A thiazolidinedione, pioglitazone, reduced TNF-alpha-induced PAI-1 production by 32%, via protein kinase C- and nuclear factor-kappaB-dependent pathways. The 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor cerivastatin inhibited TNF-alpha-induced PAI-1 production by 59%, which was reversed by coincubation with mevalonic acid. In conclusion, obesity and TNF-alpha up-regulation of PAI-1 expression in human hepatocytes may contribute to the impairment of the fibrinolytic system, leading to the development of atherosclerosis and liver fibrosis in insulin-resistant individuals. A thiazolidinedione and a 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor may thus be candidate drugs to inhibit obesity-associated hepatic PAI-1 production.

Pleiotropic effects of sitagliptin versus voglibose in patients with type 2 diabetes inadequately controlled via diet and/or a single oral antihyperglycemic agent: a multicenter, randomized trial.

PURPOSE: A step-up strategy for diet therapy and/or single oral antihyperglycemic agent (OHA) regimens has not yet been established. The aim of this study was to evaluate hemoglobin A1c (HbA1c) as a primary end point, and the pleiotropic effects on metabolic and cardiovascular parameters as secondary end points, of sitagliptin versus voglibose in patients with type 2 diabetes with inadequate glycemic control while on diet therapy and/or treatment with a single OHA. METHODS: In this multicenter, randomized, open-label, parallel-group trial, a total of 260 patients with inadequately controlled type 2 diabetes (HbA1c levels >6.9%) were randomly assigned to receive either sitagliptin (50 mg, once daily) or voglibose (0.6 mg, thrice daily) for 12 weeks. The primary end point was HbA1c levels. RESULTS: Patients receiving sitagliptin showed a significantly greater decrease in HbA1c levels (-0.78±0.69%) compared with those receiving voglibose (-0.30±0.78%). Sitagliptin treatment also lowered serum alkaline phosphatase levels and increased serum creatinine, uric acid, cystatin-C and homeostasis model assessment-ß values. Voglibose increased low-density lipoprotein-cholesterol levels and altered serum levels of several fatty acids, and increased Δ-5 desaturase activity. Both drugs increased serum adiponectin. The incidence of adverse events (AEs) was significantly lower in the sitagliptin group, due to the decreased incidence of gastrointestinal AEs. CONCLUSIONS: Sitagliptin shows superior antihyperglycemic effects compared with voglibose as a first-line or second-line therapy. However, both agents possess unique pleiotropic effects that lead to reduced cardiovascular risk in Japanese people with type 2 diabetes. TRIAL REGISTRATION NUMBER: UMIN 000003503.

Laparoscopic Management of a Complex Adrenal Cyst.

Adrenal cysts are rare, and their clinical management remains controversial. We report a case involving an adrenal cyst with a complicated appearance on radiological studies. Unenhanced computed tomography revealed a unilocular, noncalcified, hypoattenuating mass with a thin wall in the left adrenal gland. The lesion gradually increased in size from 10 to 50 mm at two-year follow-up. On contrast-enhanced magnetic resonance imaging, a mural nodule with contrast enhancement was observed. The entire adrenal gland was excised en bloc via a lateral transperitoneal laparoscopic approach without violating the principles of surgical oncology. The pathological diagnosis was an adrenal pseudocyst. Laparoscopic adrenalectomy is a safe option for the treatment of complex adrenal cysts, while maintaining the benefits of minimal invasiveness.

Renoprotective effects of atorvastatin compared with pravastatin on progression of early diabetic nephropathy.

INTRODUCTION: Several studies have shown that statins suppress the progression of diabetic nephropathy. However, few reports have directly compared the renoprotective effects between potent and conventional statins. MATERIALS AND METHODS: Patients with diabetic nephropathy, selected as those with a serum creatinine level of 0.9-1.5 mg/dL and simultaneously having either microalbuminuria or positive proteinuria, were randomly assigned to one of three groups: a conventional diet therapy group, a group given 10 mg of pravastatin and a group given 10 mg of atorvastatin. Renal function was evaluated before and after a 12-month period of therapy. RESULTS: The atorvastatin group had a significant decrease in low-density lipoprotein cholesterol at 3 months and thereafter compared with the other groups. The urinary albumin-to-creatinine ratio significantly decreased in the atorvastatin group; the degree of this decrease was significantly greater than that in the diet therapy group. The kidney function estimated with cystatin C (CysC) and the estimated glomerular filtration rate calculated from CysC were significantly preserved in the atorvastatin group compared with the pravastatin group. In a multivariate regression analysis, the use of atorvastatin was the only explanatory variable for the changes in CysC; this was independent of changes in low-density lipoprotein cholesterol. CONCLUSIONS: Atorvastatin is more effective than pravastatin for the prevention of increase in CysC, and this renoprotective effect was considered to a result of the pleiotropic effect of atorvastatin independent of its lipid-lowering effect. This study was registered with UMIN (no. UMIN 000001774).
