RESUMO
In certain cases, it is difficult to distinguish hepatic sarcoidosis from malignant lymphoma or drug-induced liver injury and to select the proper treatment for this condition. The present study describes the case of a female patient in her 30s who was referred to the hospital due to fever, arthralgia, myalgia and abnormal liver function test results for 4 months. A laboratory examination revealed elevated levels of serum angiotensin-converting enzyme (ACE) and soluble interleukin-2 receptor (sIL-2R), as well as an increase in serum hepatic and biliary tract enzymes. Gallium scintigraphy revealed a marked uptake in the liver, as well as an uptake in the mediastinal, inguinal and external iliac lymph nodes. Magnetic resonance imaging revealed extensive hepatosplenomegaly with multiple non-enhancing splenic nodules. Hepatic sarcoidosis was diagnosed by a liver biopsy as non-caseating hepatic granulomas, and multinucleated giant cells were observed. The patient responded to treatment with 20 mg prednisolone daily, and exhibited an improvement in her symptoms. An improvement was also observed in her serum levels of ACE, sIL-2R, and serum hepatic and biliary tract enzymes; decreased gallium uptake in the liver was also observed. On the whole, the present case report reconfirms that liver biopsy is a useful diagnostic tool for hepatic sarcoidosis.
RESUMO
Hepatocellular carcinoma (HCC) is a common malignancy with a poor prognosis, particularly in patients with advanced-stage disease, elderly individuals and/or in those with poor liver function. Immune checkpoint inhibitor-containing therapies, such as atezolizumab, an anti-programmed death ligand-1 monoclonal antibody, plus bevacizumab, an anti-vascular endothelial growth factor monoclonal antibody, may be effective and safe therapeutic options for elderly patients with advanced-stage HCC. The present study reports the case of a male patient his 80s who consumed alcohol with unresectable advanced-stage HCC who received combination therapy comprising atezolizumab plus bevacizumab for 6 months. The patient achieved a complete response despite the discontinuation of treatment due to nephrotoxicity. It is critical for patients with HCC and a Child-Pugh A grade to continue therapy for HCC, even if they are older. The development of more effective therapies is required for patients with advanced-stage HCC with a worse liver function than those with a Child-Pugh A grade. The case described in the present study demonstrates the need for obtaining further evidence regarding the efficacy and safety of the combination therapy including atezolizumab plus bevacizumab for elderly patients with advanced-stage HCC.
RESUMO
OBJECTIVE: Degree of indication for epilepsy surgery is determined by taking multiple factors into account. This study aimed to investigate the usefulness of the Specific Consistency Score (SCS), a proposed score for focal epilepsy to rate the indication for epilepsy focal resection. METHODS: This retrospective cohort study included patients considered for resective epilepsy surgery in Kyoto University Hospital from 2011 to 2022. Plausible epileptic focus was tentatively defined. Cardinal findings were scored based on specificity and consistency with the estimated laterality and lobe. The total points represented SCS. The association between SCS and the following clinical parameters was assessed by univariate and multivariate analysis: (1) probability of undergoing resective epilepsy surgery, (2) good postoperative seizure outcome (Engel I and II or Engel I only), and (3) lobar concordance between the noninvasively estimated focus and intracranial electroencephalographic (EEG) recordings. RESULTS: A total of 131 patients were evaluated. Univariate analysis revealed higher SCS in the (1) epilepsy surgery group (8.4 [95% confidence interval (CI) = 7.8-8.9] vs. 4.9 [95% CI = 4.3-5.5] points; p < .001), (2) good postoperative seizure outcome group (Engel I and II; 8.7 [95% CI = 8.2-9.3] vs. 6.4 [95% CI = 4.5-8.3] points; p = .008), and (3) patients whose focus defined by intracranial EEG matched the noninvasively estimated focus (8.3 [95% CI = 7.3-9.2] vs. 5.4 [95% CI = 3.5-7.3] points; p = .004). Multivariate analysis revealed areas under the curve of .843, .825, and .881 for Parameters 1, 2, and 3, respectively. SIGNIFICANCE: SCS provides a reliable index of good indication for resective epilepsy surgery and can be easily available in many institutions not necessarily specializing in epilepsy.

Hepatitis E virus (HEV) infection occasionally causes acute-on-chronic liver failure in patients with alcohol-associated cirrhosis. These reports have been published mainly from highly HEV genotype 1-endemic countries. The present study describes the case of a patient with severe HEV genotype 3b infection and alcohol-associated liver disease. A male patient in his 70s who consumed alcohol, and who had begun consuming alcohol at the age of 12, had high levels of alanine aminotransferase (ALT) and total bilirubin. The peak levels of ALT and total bilirubin were 1,067 IU/l and 26.3 mg/dl, respectively. A computed tomography scan revealed an atrophic liver. Upon admission, both anti-HEV immunoglobulin A and HEV RNA were positive, and his HEV was genotype 3b. He also had chronic kidney disease, as his estimated glomerular filtration rate was <45 ml/min/1.73 m2, and ribavirin could not be used. The abnormal levels of the liver function parameters of the patient gradually improved due to conservative treatment, and he was discharged on day 43. On the whole, the present study demonstrates that careful attention should be paid to patients with viral hepatitis, including hepatitis E, when alcohol-associated liver disease is present. Novel anti-HEV drugs need to be developed for severe HEV infections with chronic kidney disease.
RESUMO
Background and Objectives: Muscle cramps are often observed in patients with liver diseases, especially advanced liver fibrosis. The exact prevalence of muscle cramps in outpatients with liver diseases in Japan is unknown. Patients and Methods: This study examined the prevalence of, and therapies for, muscle cramps in outpatients with liver diseases in Tokyo, Japan. A total of 238 outpatients with liver diseases were retrospectively examined. We investigated whether they had muscle cramps using a visual analog scale (VAS) (from 0, none, to 10, strongest), and also investigated their therapies. Results: Muscle cramps were observed in 34 outpatients with liver diseases (14.3%); their mean VAS score was 5.53. A multivariate analysis demonstrated that older age (equal to or older than 66 years) was the only significant factor as-sociated with muscle cramps. The prevalence of muscle cramps among patients with liver diseases seemed not to be higher. The problem was that only 11 (32.4%) of 34 outpatients received therapy for their muscle cramps. Conclusions: Only age is related to muscle cramps, which is rather weak, and it is possible that this common symptom may not be limited to liver disease patients.

BACKGROUND: Early laparoscopic cholecystectomy (ELC) for acute cholecystitis (AC) poses multiple challenges. The Tokyo Guidelines 2018 (TG18) eliminated the time limit (< 72 h) and expanded the surgical indication to severe AC. This study aimed to evaluate the clinical outcomes of ELC for AC following the TG18 in a single high-volume center. METHODS: From 2019 to 2021, we managed all AC patients with a TG18 flowchart and prospectively enrolled those who underwent ELC within 7 days of symptom onset. The primary outcome was overall morbidity, with a comparison between mild (Grade I) and moderate/severe (Grade II/III) AC. RESULTS: During the study period, 201 patients underwent ELC was for Grade I (56.2%), II (40.3%), and III (3.5%) ACs. Mean age was 69 ± 15.2 years and time to surgery from symptom onset was 0 (12.9%), 1-3 (66.7%), and 4-7 days (20.4%). Mean operative time and blood loss were 118.9 ± 42.7 min and 57.8 ± 99.4 mL, respectively. The critical view of safety (CVS) was achieved in 76.1% of patients, and bailout procedures were performed in 21.4%. There were no open conversions or bile duct injuries. Major morbidities (Clavien-Dindo classification ≥ IIIa) were observed in 5.5% of cases and mortality in 0.5%. Comparing Grades II/III to Grade I, operative time was longer (112.3 vs. 127.3 min, p = 0.014), blood loss was higher (40.3 vs. 80.1 mL, p = 0.005), the CVS rate was lower (83.2 vs. 67.0%, p = 0.012), and the major morbidity rate was higher (1.8 vs. 10.2%, p = 0.012). In the subgroup analysis of Grade II/III, there were no significant differences in major morbidities (p = 0.288) between the two groups (0-3 vs. 4-7 days). CONCLUSION: ELC for AC following TG18 is feasible with low morbidity rates. However, ELC for Grade II/III ACs remains challenging, and surgeons must carefully assess intraoperative difficulties and surgical risks before proceeding.

The hepatitis C virus (HCV) causes acute and chronic hepatitis, cirrhosis, and hepatocellular carcinoma, as well as extrahepatic manifestations such as malignant lymphoma. Currently, direct-acting antiviral agents (DAAs) against HCV infection can lead to a sustained virological response (SVR) in almost all HCV-infected patients. In this review article, we discuss acute exacerbation and alanine aminotransferase (ALT) flare in patients with chronic HCV infection. Although acute liver failure caused by HCV infection is rare, careful attention should be paid to the cases with ALT elevation during the natural course of chronic HCV infection. HCV genotype 2 infection, the use of rituximab, and a higher dose of corticosteroid are factors associated with HCV acute exacerbation and ALT flare. Treatment regimens for cancer have been interrupted or changed due to ALT flare due to HCV infection in some patients undergoing chemotherapy for cancer. The pathogenesis of HCV acute exacerbation and ALT flare could involve cellular as well as humoral immune responses. In the DAA era, the earlier introduction of DAAs may prevent chronic HCV-infected patients with acute exacerbation and ALT flare from developing into a more severe form, although DAAs may not be effective for all of them.

Community-acquired pneumonia (CAP) is an acute pulmonary parenchymal infection acquired outside the hospital. The utility of blood cultures in inpatients with CAP to reduce mortality and length of hospital stay is controversial. This study aimed to determine the utility of blood cultures on the first day of hospitalization for CAP inpatients and its influence on mortality, length of hospital stay, and antibiotics use. We conducted a fact-finding survey on the implementation of blood culture in inpatients with CAP in Japan. A propensity score (PS)-matched analysis based on the National Database of Health Insurance Claims and Specific Health Check-ups of Japan database was conducted. Overall, 163173 patients were included in the analysis, and PS matching extracted 68104 pairs. The results of the comparison between the PS-matched blood culture group and PS-matched control group were as follows: mortality and length of hospital stay were significantly lower in the PS-matched blood culture group than in the control group. The adjusted odds ratio (OR) (95% confidence interval (CI)) for in-hospital mortality with blood culture test was 0.73 (0.68-0.79). Moreover, for days of antibiotic usage, number of antibiotics used were significantly higher in the PS-matched blood culture group than that in the control group. Our findings indicated that performing a blood culture on the first day of hospitalization for inpatients with CAP was associated with reduced mortality. To our knowledge, this is the largest epidemiological study to assess the utility of blood culture in Japanese inpatients with CAP. This testing method shows potential for application in clinical practice.

OBJECTIVE: The aim of this study was to investigate the safety and survival benefits of portal vein and/or superior mesenteric vein (PV/SMV) resection with jejunal vein resection (JVR) for pancreatic ductal adenocarcinoma (PDAC). SUMMARY BACKGROUND DATA: Few studies have shown the surgical outcome and survival of pancreatic resection with JVR, and treatment strategies for patients with PDAC suspected of jejunal vein (JV) infiltration remain unclear. METHODS: In total, 1260 patients who underwent pancreatectomy with PV/ SMV resection between 2013 and 2016 at 50 facilities were included; treatment outcomes were compared between the PV/SMV group (PV/ SMV resection without JVR; n = 824), PV/SMV-J1 V group (PV/SMV resection with first jejunal vein resection; n = 394), and PV/SMV-J2,3 V group (PV/SMV resection with second jejunal vein or later branch resection; n = 42). RESULTS: Postoperative complications and mortality did not differ between the three groups. The postoperative complication rate associated with PV/ SMV reconstruction was 11.9% in PV/SMV group, 8.6% in PV/SMV-J1 V group, and 7.1% in PV/SMV-J2,3V group; there were no significant differences among the three groups. Overall survival did not differ between PV/SMV and PV/SMV-J1 V groups (median survival; 29.2 vs 30.9 months, P = 0.60). Although PV/SMV-J2,3 V group had significantly shorter survival than PV/SMV group who underwent upfront surgery ( P = 0.05), no significant differences in overall survival of patients who received preoperative therapy. Multivariate survival analysis revealed that adjuvant therapy and R0 resection were independent prognostic factors in all groups. CONCLUSION: PV/SMV resection with JVR can be safely performed and may provide satisfactory overall survival with the pre-and postoperative adjuvant therapy.

The association between neurocognitive function (NCF) impairment and brain cortical functional connectivity in glioma patients remains unclear. The correlations between brain oscillatory activity or functional connectivity and NCF measured by the Wechsler Adult Intelligence Scale full-scale intelligence quotient scores (WAIS FSIQ), the Wechsler Memory Scale-revised general memory scores (WMS-R GM), and the Western aphasia battery aphasia quotient scores (WAB AQ) were evaluated in 18 patients with left frontal glioma using resting-state electroencephalography (EEG). Current source density (CSD) and lagged phase synchronization (LPS) were analyzed using exact low-resolution electromagnetic tomography (eLORETA). Although 2 and 2 patients scored in the borderline range of WAIS FSIQ and WMS-R GM, respectively, the mean WAIS FSIQ, WMS-R GM, and WAB AQ values of all patients were within normal limits, and none had aphasia. In the correlation analysis, lower WMS-R GM was associated with a higher LPS value between the right anterior prefrontal cortex and the left superior parietal lobule in the beta1 band (13-20 Hz, R = - 0.802, P = 0.012). These findings suggest that LPS evaluated by scalp EEG is associated with memory function in patients with left frontal glioma and mild NCF disorders.

BACKGROUND: Eradication of hepatitis C virus (HCV) from chronic HCV-infected patients could improve liver function and prevent hepatocarcinogenesis in the long term. Eradication of HCV by direct-acting antivirals (DAAs) also leads to dynamic immunological changes. We report a case of recurrent coronavirus disease 2019 (COVID-19) that developed immediately after combination treatment with DAAs for HCV infection and decompensated cirrhosis. CASE REPORT: A 55-year-old male was started on a 12-week treatment with combination of HCV NS5A inhibitor velpatasvir and HCV NS5B polymerase inhibitor sofosbuvir. HCV RNA became undetectable after six weeks of treatment and was undetectable at the end of the treatment (EOT). Twelve days after the EOT, we diagnosed the patient with COVID-19 pneumonia, admitted him to our hospital and he was discharged two weeks later. One week after his discharge, he visited our hospital again, was diagnosed with recurrent COVID-19 pneumonia readmitted for a second time. Four days after second admission, cardiac arrest occurred, however, he recovered from severe COVID-19 and achieved sustained virological response and his liver function improved. CONCLUSION: In the COVID-19 era, while attention should be paid to the occurrence or exacerbation of infection, including COVID-19, interferon-free DAA combination therapy should be performed for HCV-infected individuals.

Background and Objectives: Balloon-occluded retrograde transvenous obliteration (BRTO) could be currently one of the best therapies for patients with gastric varices. This study examined the exacerbation rates for esophageal varices following BRTO for gastric varices in patients with hepatic cirrhosis. Materials and Methods: We enrolled 91 cirrhotic patients who underwent BRTO for gastric varices. In total, 50 patients were examined for exacerbation rates of esophageal varices following BRTO. Esophageal varices and their associated exacerbation were evaluated by upper gastrointestinal endoscopy. Patients were allocated into two groups according to the main inflow tract for gastric varices: (1) 37 patients in the left gastric vein (LGV) group with an LGV width of more than 3.55 mm, and (2) 13 patients in the non-LGV group who had short gastric vein or posterior gastric vein. Moreover, treatment outcomes were retrospectively analyzed. Results: LGV width (p < 0.01) was the major risk factor for the deterioration of esophageal varices post BRTO. In addition, LGV was the most common inflow tract, and the LGV group contained 74% (37/50) of patients. The exacerbation rates of esophageal varices at 1, 2, 3, and 4 years post BRTO were 40%, 62%, 65%, and 68%, respectively. The comparison of the exacerbation rates for esophageal varices following BRTO according to inflow tract showed that the exacerbation rates were significantly higher in the LGV group than those of the non-LGV group (p = 0.03). In more than half of the subjects, LGV was the main inflow tract for gastric varices, and this group experienced more frequent exacerbations of esophageal varices following BRTO compared to patients with different inflow tract sources. Conclusion: Careful attention should be paid to the LGV width when BRTO is performed for gastric varices.

Hepatis virus C (HCV) infection causes liver cirrhosis and hepatocellular carcinoma (HCC) worldwide. The objective of our study was to examine the effects of the HCV nonstructural protein (NS) 3/4A inhibitor glecaprevir/NS5A inhibitor pibrentasvir on real-world HCV patients in the northern part of Tokyo, Japan. Although 106 patients were consecutively included, a total of 102 HCV-infected patients with chronic hepatitis or compensated cirrhosis, who received 8- or 12-week combination treatment with glecaprevir/pibrentasvir and were followed up to week 12 after the end of treatment were analyzed retrospectively. Only three patients discontinued treatment due to adverse events; however, they achieved a sustained virologic response at 12 weeks (SVR12). Finally, SVR rates were 99.0% (101/102). Only one patient without liver cirrhosis was a treatment relapser who received hepatic resection for HCC approximately two years after commencement of the 8-week combination treatment with glecaprevir/pibrentasvir. After the exclusion of patients with HCV genotype 1b and P32 deletion in the HCV NS5A region, a 12-week combination of glecaprevir/pibrentasvir led to SVR12 in all nine direct-acting antiviral-experienced patients. Glecaprevir/pibrentasvir had a high efficacy and an acceptable safety profile for real-world HCV patients in a single hospital in Japan.
RESUMO
BACKGROUND: Hepatocellular carcinoma (HCC) occasionally presents with simultaneous or metachronous primary malignancies of other organs. Despite the limited scope of cytocidal anticancer drugs or molecular targeted agents, immune checkpoint inhibitors (ICIs) can still be used for various malignancies. Here, we present cases of double cancers including HCC treated with ICIs. CASE REPORT: Case 1: A 70-year-old man with lung cancer and 80-mm HCC underwent nivolumab therapy. The sizes of both cancers remained constant for nine months. Case 2: A 58-year-old man with pharyngeal cancer and HCC. Nivolumab was administered, but was withdrawn after one session because of progressive disease. Case 3: A 71-year-old man with a 5 cm HCC invading the inferior vena cava, and early esophageal cancer. HCC showed a significant volume reduction and esophageal cancer demonstrated slight improvement by atezolizumab and bevacizumab therapy. CONCLUSION: A combination therapy including ICI is a promising treatment option for HCC with concurrent malignancies.

Patients with resectable pancreatic cancer are considered to already have micro-distant metastasis, because most of the recurrence patterns postoperatively are distant metastases. Multimodal treatment dramatically improves prognosis; thus, micro-distant metastasis is considered to be controlled by chemotherapy. The survival benefit of "regional lymph node dissection" for pancreatic head cancer remains unclear. We reviewed the literature that could be helpful in determining the appropriate resection range. Regional lymph nodes with no suspected metastases on preoperative imaging may become areas treated with preoperative and postoperative adjuvant chemotherapy. Many studies have reported that the R0 resection rate is associated with prognosis. Thus, "dissection to achieve R0 resection" is required. The recent development of high-quality computed tomography has made it possible to evaluate the extent of cancer infiltration. Therefore, it is possible to simulate the dissection range to achieve R0 resection preoperatively. However, it is often difficult to distinguish between areas of inflammatory changes and cancer infiltration during resection. Even if the "dissection to achieve R0 resection" range is simulated based on the computed tomography evaluation, it is difficult to identify the range intraoperatively. It is necessary to be aware of anatomical landmarks to determine the appropriate dissection range during surgery.
RESUMO
Recently, the use of immune checkpoint inhibitors (ICIs) with or without chemotherapeutic agents has been increasing in the treatment for advanced cancer. Here, we report the occurrence of liver failure after the use of pembrolizumab in an 82-year-old woman with metastatic liver disease derived from right advanced renal pelvis, ureteral cancer, and bladder cancer. She was successfully treated with 0.6 mg/kg daily prednisolone. In patients treated with ICIs, ICI-induced hepatitis is occasionally observed. Even if patients are older, it appears important to diagnose and treat ICI-induced hepatitis earlier by multidisciplinary therapies including steroid treatment. This is a first report of pembrolizumab-induced liver failure in elder patient with age over 80 years. Even if patients are older, it appears important to diagnose and treat ICI-induced hepatitis earlier by multidisciplinary therapies including steroid treatment.
RESUMO
A 74-year-old man with a history of transfusion at 35 years old in Egypt was referred to our hospital. He was infected with hepatitis C virus (HCV) genotype 4 (GT4), which is a rare HCV GT in Japan, and was also diagnosed with hepatic compensated cirrhosis. We safely treated the patient for 12 weeks with the combination of glecaprevir and pibrentasvir, and a sustained virologic response (SVR) was achieved. This is the first report of HCV GT4 infection in a treatment-naïve Japanese patient with cirrhosis in whom SVR was achieved with the combination treatment of glecaprevir and pibrentasvir.

Recently, we experienced an outbreak of acute hepatitis A virus (HAV) infection between 2018 and 2020. Herein, we describe this male-dominant HAV infection outbreak observed among non-human immunodeficiency virus (HIV)-infected persons in the northern part of Tokyo, Japan. Clinical information was collected from patient interviews and from medical record descriptions. In the present study, 21 patients were retrospectively analyzed. A total of 90.4 and 33.3% of patients were males, and men who have sex with men (MSM), respectively. The total bilirubin levels and platelet counts tended to be lower in the MSM group than in the non-MSM group. C-reactive protein (CRP) levels tended to be higher in acute liver failure (ALF) patients than in non-ALF patients. Prolonged cholestasis was observed in one patient (4.8%). We also found that 18 HAV isolates belonged to HAV subgenotype IA/subgroup 13 (S13), which clustered with the HAV isolate (KX151459) that was derived from an outbreak of HAV infection among MSM in Taiwan in 2015. Our results suggest that the application of antivirals against HAV, as well as HAV vaccines, would be useful for the treatment and prevention of severe HAV infection.

BACKGROUND: Duct-to-mucosa pancreaticojejunostomy (PJ) after pancreaticoduodenectomy (PD) is technically challenging, particularly in cases of soft pancreas with a nondilated main pancreatic duct (MPD). We propose a novel procedure that involves ligating the pancreas in advance to allow for MPD dilation. METHODS: We compared the data of 16 patients who underwent PD followed by PJ with advance ligation (AL) for soft pancreas with a nondilated MPD with that of 17 patients who underwent a conventional procedure (conventional group) without AL at a single institution between January 2015 and April 2017. MPD diameters were assessed using preoperative computed tomography and intraoperative ultrasonography. Pancreatic consistency was judged intraoperatively. The pancreatic parenchyma and MPD were ligated in advance to allow time for MPD dilation. After AL, we divided the pancreatic parenchyma. AL led to MPD dilation and facilitated PJ. RESULTS: There were significantly fewer complications in the AL group than in the conventional group (P=0.005). There were no cases of pancreatitis or death in either group. The mean procedural time for occluding the MPD was 43 min (range, 21-134 min). The median MPD dilation rate after AL was 1.6 (0.9-3.8). CONCLUSIONS: AL is a simple, safe, and useful procedure for facilitating PJ.
RESUMO
OBJECTIVE: The aim of this study was to describe laparoscopic anatomical parenchymal sparing liver resections for hepatocellular carcinoma (HCC) and colorectal liver metastases (CRLM) and report the short-term outcomes. BACKGROUND: Anatomical resections (ARs) have better oncological outcomes compared to partial resections in patients with HCC, and some suggest should be performed also for CRLM as micrometastasis occurs through the intrahepatic structures. Furthermore, remnant liver ischemia after partial resections has been associated with worse oncological outcomes. Few experiences on laparoscopic anatomical resections have been reported and no data on limited AR exist. METHODS: We performed a retrospective analysis of 86 patients undergoing full laparoscopic anatomical parenchymal sparing resections with preoperative surgical simulation and standardized procedures. RESULTS: A total of 55 patients had HCC, whereas 31 had CRLM with a median of 1 lesion and a size of 30âmm. During preoperative three-dimensional (3D) simulation, a median resection volume of 120 mL was planned. Sixteen anatomical subsegmentectomies, 56 segmentectomies, and 14 sectionectomies were performed. Concordance between preoperative 3D simulation and intraoperative resection was 98.7%. Two patients were converted, and 7 patients experienced complications. Subsegmentectomies had comparable blood loss (166âmL, P = 0.59), but longer operative time (426âmin, P = 0.01) than segmentectomies (blood loss 222 mL; operative time 355âmin) and sectionectomies (blood loss 120 mL; operative time 295âmin). R0 resection and margin width remained comparable among groups. CONCLUSIONS: A precise preoperative planning and a standardized surgical technique allow to pursue the oncological quality of AR enhancing the safety of the parenchyma sparing principle, reducing surgical stress through a laparoscopic approach.
