ALCOHOL-RELATED SUDDEN DEATH WITH HEPATIC FATTY METAMORPHOSIS: A COMPREHENSIVE CLINICOPATHOLOGICAL INQUIRY INTO ITS PATHOGENESIS

To clarify the pathogenesis of the widely known but obscuresyndrome of sudden death with hepatic fatty metamorphosis observedin alcohol abusers, we have scrutinized both the clinical andpathological data of 11 subjects who died under such circumstancesbetween 1987 and 1993. Death followed several days of uninterrupteddrinking often with little dietary intake. The notable clinicalfeatures on arrival at the emergency room were disturbance ofconsciousness (11/11), hypotension (47/6), hypothermia (3/5),hypoglycaemia (8/11), metabolic acidosis (6/6), renal dysfunction(11/11), and hyperammonaemia (5/5). The common hepatic pathologywas the extensive appearance of numerous microvesicular fattydroplets in the hepatocytes together with varying degrees ofmacrovesicular fatty change; four subjects had an underlyingcirrhosis. Death undoubtedly results from a variety of metabolicdisturbances triggered by the combination of massive ethanolintake and starvation. The appearance of extensive microvesicularfatty change superimposed on macrovesicular fatty change wasconsidered to be an associated phenomenon     

THE IMPACT OF DIABETES MELLITUS ON THE PROGNOSIS OF ALCOHOLICS

In this study, the mortality of clinically treated Japanesealcoholics with diabetes mellitus was analysed. Fifty-one diabeticalcoholics without liver cirrhosis (DM), 23 diabetic and cirrhoticalcoholics (DM LC), 44 cirrhotic alcoholics without diabetes(LC), and 354 alcoholics without either complication (AL) admittedto the National Institute on Alcoholism in 1985 were studied.Thirty-seven diabetics required insulin treatment, and 12 oralhypoglycemic agents. The 4.4-year survival and drinking statusafter discharge were studied in 1990. Stepwise logistic regressionanalysis showed that the estimated odds for death increased8.10, 4.38, 3.70, and 3.27 times for the subjects with the alcoholmisuse after discharge, DM, DM LC, and LC, respectively. The4.4-year survival rate of alcoholics who continued misusingalcohol was much lower in DM (26%, P < 0.0005) and LC (35%,P < 0.0001) than in AL (73%). The survival rate of thosewho stopped misusing alcohol was significantly higher in DM(90%, P < 0.0001), LC (88%, P < 0.0001) and AL (94%, P< 0.0005) than those who continued misusing alcohol. Therewas no significant difference in the survival rate between thealcoholics with DM LC who continued misusing alcohol (50%) andthose who stopped misusing alcohol (73%). In the dead patients,56% of DM died unexpectedly or suddenly, whereas 71% of LC diedof liver failure after hospitalization. These results suggestthat diabetic alcoholics should be intensively educated forabstinence.     

Development of Gastroesophageal Varices and Risk of Variceal Bleeding in Patients With Cirrhosis

Abstract: We studied the relationships between portal pressure measured using the portal venous pressure gradient, the development of gastroesophageal varices, and the risk of variceal bleeding in 56 patients with cirrhosis. Portal pressure was higher in patients with varices than in those without (P>0.01), and 11 mmHg was the lowest portal pressure measured in the patients with varices. The size of the varices was not associated with the portal pressure. There was no difference in the value of portal pressure measurements for the patients with variceal bleeding and those without and there was no linear-relationship between the degree of portal hypertension and the rate of variceal bleeding. 12 mmHg was the lowest portal pressure measured in the patients with variceal bleeding. The size of the varices was related to the rate of variceal bleeding (P>0.05). We conclude that (a) a portal pressure of 11 mmHg is necessary for the formation of varices, (b) 12 mmHg of portal pressure is necessary for variceal bleeding to occur but the degree of portal hypertension has no predictive value for the risk of variceal bleeding, and (c) the size of the varices does not depend on the degree of portal hypertension but is associated with the risk of variceal bleeding.     

Conduction Delay in Right Ventricle as a Marker for Identifying High‐Risk Patients With Brugada Syndrome

Conduction Delay as a Marker for Brugada Syndrome. Objectives: To evaluate the significance of conduction delay (CD) in the right ventricle (RV) in Brugada syndrome (BS) as a marker for risk stratification of sudden death. Methods: Twenty‐five patients with BS (7 with documented ventricular fibrillation (VF), 8 with syncope, and 10 without symptoms) and 10 control subjects were paced from the RV apex using 8 beats of drive pacing and a single extra‐stimulus. CDs in the right ventricular outflow tract (RVOT) (CD‐RV) and in the lateral left ventricle (L‐LV) (CD‐LV), and the local electrogram durations at a single extra‐stimulus in RVOT (D‐RV) and L‐LV (D‐LV) were calculated. We also evaluated changes in 12‐lead ECG parameters in 16 patients with BS after pilsicainide challenge test (Pilsicainide‐test). Results: Maximal CD‐RV and maximal D‐RV were significantly larger than maximal CD‐LV and maximal D‐LV in BS (26 ± 10 and 105 ± 15 vs 20 ± 6 and 92 ± 15 ms, P < 0.05, respectively). Maximal CD‐RV and maximal D‐RV in patients with documented VF were the largest among the 3 groups. There was a significant positive correlation between maximal CD‐RV or maximal D‐RV and changes in QRS duration in leads V2 and V5 and in S wave duration in lead II and V5 after Pilsicainide‐test (CD‐RV; r = 0.54, 0.51, 0.56, and 0.53: D‐RV; r = 0.55, 0.5, 0.57, and 0.53, P < 0.05, respectively). In control subjects, there were no significant differences. Conclusions: CD in RV was a useful marker for identifying high‐risk patients with BS. CD in the RV, especially in the RVOT epicardium, may be related to arrhythmias in BS. (J Cardiovasc Electrophysiol, Vol. 21, pp. 688‐696, June 2010)     

Nodular granulomatous phlebitis of the skin: a fourth type of tuberculid

We present five cases of granulomatous phlebitis of the skin and compare them with a case of miliary tuber-culosis with granulomatous phlebitis. All five patients were hypersensitive to purified protein derivative, but without active tuberculosis. Although anti-tuberculous drugs were effective, no tubercle bacilli were isolated from the skin. Clinically, subcutaneous nodules were felt along the course of the leg vein. Histologically, epithelioid cell granulomas with Langhans' giant cells were observed within the walls of the cutaneous veins. In a later stage, granulomatous panniculitis was often associated. Using the polymerase chain reaction method, Mycobacterium tuberculosis DNA was detected in four of the five cases of granulomatous phlebitis of the skin. Granulomatous phlebitis of the skin seems to represent a relatively early phase of delayed-type hypersensitivity reactions to Mycobacterium tuberculosis and may represent a distinct entity different from other types of tuberculid—a new tuberculid. Nevertheless, before making the diagnosis, the possibility of true tuberculosis must always be excluded. Nodular granulomatous phlebitis of the skin would be an appropriate name for the newly described condition.     

Efficacy of 308-nm excimer light for Japanese patients with psoriasis

Ultraviolet irradiation therapy, including psoralen and ultraviolet A therapy and narrow-band ultraviolet B (310–312 nm) therapy, is a widely used and highly efficient treatment modality for psoriasis. Therapy with 308-nm excimer light has been reported to be effective for the treatment of psoriasis vulgaris. To evaluate the efficacy of 308-nm excimer light therapy for Japanese psoriasis patients, seven patients (six men and one woman) with plaque-type psoriasis were treated with 308-nm excimer light at 7–14-day intervals. The Psoriasis Severity Index (PSI) was calculated for individual plaques in order to assess the effectiveness of the therapy. A 74.9% mean improvement in the PSI was observed after 10 treatment sessions. These results suggested that targeted irradiation with 308-nm excimer light leads to rapid and selective improvement in plaque-type psoriatic lesions without unnecessary radiation exposure to the surrounding unaffected skin.
