Episodes of depression and acute psychosis in two patients receiving propranolol hydrochloride are described, and the literature on propranolol-induced depression and psychosis is reviewed. A 42-year-old woman developed severe depression, marked apathy, social withdrawal, and anorexia after taking propranolol hydrochloride (80 mg/day) for three months to control her hypertension. Five days after the dose was reduced to 40 mg/day, there was a major improvement in her depressive symptoms, with a complete resolution in eight days. Upon rechallenge with 80 mg/day of propranolol, she again experienced depressive symptoms. Atenolol 50 mg/day was substituted for the propranolol therapy, and she exhibited a complete remission of her depression. The second patient was a 63-year-old man who had been taking propranolol hydrochloride 160 mg/day for three months without incident. Because of an increased frequency of anginal attacks, the dosage was increased to 240 mg/day. Within two days, he demonstrated such agitation, excitement, and combativeness that he had to be controlled with a 25-mg dose of methotrimeprazine. When the propranolol dose was reduced to 160 mg/day, his psychotic symptoms rapidly cleared. However, when the dose was subsequently increased to 200 mg/day, he again showed increased agitation. After substituting atenolol 100 mg/day for propranolol, the patient's mental status returned to normal. Both of these patients experienced symptoms that were temporarily associated with propranolol. Both patients were subsequently controlled without symptoms with atenolol therapy. Propranolol is a highly lipophilic beta blocker that achieves high concentrations in the brain. When continued beta-blocking therapy is necessary or beta blockade is indicated, a weakly lipophilic agent such as atenolol is indicated.

We present the case of a 64-year-old alcoholic who had suffered two episodes of hemorrhage from esophageal varices. For control of variceal hemorrhage, he underwent a distal splenorenal shunt. His immediate postoperative course was complicated by the development of marked ascites and intermittent episodes of encephalopathy. Routine postoperative angiography was performed after 4 months and demonstrated a fistula between the left gastric artery and vein. Patency of the shunt was demonstrated by direct percutaneous splenoportography. Two months after this admission, the patient was readmitted with the complaints of anorexia and nausea. Marked encephalopathy was noted. Eight hours following admission, he developed acute abdominal distention and hypotension. An abdominal tap revealed bloody fluid, and the patient was immediately prepared for transport to the operating room. He suffered cardiac arrest during transport, and all efforts at resuscitation were unsuccessful. Although a postmortem examination was not performed, it is suspected the arteriovenous fistula resulted in severe portal venous hypertension leading to intraperitoneal rupture of one of the affected veins, producing a massive hemoperitoneum.

Fifty women with refractory obesity received phentermine resinate. Seven were withdrawn because of side-effects: three developed severe headaches, one each hypertension, depressive symptoms, breathlessness and palpitations with irritability. The mean weight loss in the 34 who completed the 20-week study was 6.4 kg. Nine lost 10 kg or more. Sustained appetite suppression was related to weight loss. Plasma phentermine concentrations did not correlate with the severity of the obesity problem, the degree of subjective anorexia or with weight loss. Poor initial response to standard dosage of phentermine is unlikely to improve with higher dosage. The individual's response to phentermine is unpredictable and appears to relate to factors other than the plasma drug concentration.

A woman, now 28 years old, was diagnosed 6 years ago as chronic glomerulonephritis by renal biopsy. From August 15, 1975 she complained of nausea, loss of appetite and weight (about 7 kg within 2 weeks). Severe hypertension (200/130 mmHg), hyponatremia (123 mEq/liter), anemia, elevated plasma renin activity (PRA), advanced azotemia, and eye ground changes of KW-II were found. Dialysis treatment was started on September 2, 1975. From November 1975 massive amounts of sodium (5,000 mEq or more monthly) and water (26 liters or more monthly) were removed by the dialysis. These intensive dialyses resulted in an elevated PRA with recurrence of severe hypertension. At the end of March 1976 she became almost blind with retinopathy of KW-IV. Potent hypotensive drugs including beta-blockers were administered, but no improvements were obtained. On March 31, 1976 nephrectomy was performed to save her life. Marked hyalinization of glomeruli and heavy thickening of intima in interlobular arteries were found in the removed kidneys. Renal artery stenosis was not recognized either macroscopically or histologically. In this patient, the amount of sodium removed by the dialysis was dependent on her diastolic blood pressure and sodium concentration of the dialysis. It may be concluded that too enthusiastic dialysis may develop malignant hypertension due to excessive renin release.

The authors present a case report of a 62-year old woman, with hypertension for many years. She suffered from weakness, anorexia and weight loss in the last 6 months. On admission, anemia, elevated ESR, haematuria, proteinuria and renal failure were present. Renal biopsy was compatible with chronic glomerulonephritis. The clinical picture and positivity for P-ANCA suggested systemic vasculitis. Later evidence of maxillary sinusitis and nasal mucosae ulcers as well as pneumonitis, although biopsy did not reveal granulomas, suggested the diagnosis of Wegener Vasculitis. Medicated with Cyclophosphamide and Prednisolone, for a year, with improvement. The authors make a brief discussion of the clinical criteria for classification of ANCA-associated systemic vasculitis.

During normal pregnancy, serum transaminase levels remain within normal limits. An elevated level observed in a pregnant woman always signals a disease process, most often of hepatic origin, but in certain cases, of muscular origin. During the last three months of pregnancy and in the immediate post partum period a large number of liver diseases can cause elevated transaminase levels, depending upon the clinical presentation. In everyday practice, a complete liver battery together with specialized consultation is required for all pregnant women with raised transaminase levels. Toxaemia gravis may be evident in patients with severely raised blood pressure, especially if seizures occur. Epigastric or subcostal pain should suggest hepatic involvement. Hypertension may however be absent and epigastric or left shoulder pain may be the only clinical signs. Acute liver steatosis is 20 to 50 times more rare than toxaemia and may cause nausea and vomiting. Certain non-specific signs such as asthenia, anorexia, polyalgia, abdominal pain, diarrhoea and fever, together with pruritus should suggest acute hepatitis. A 25-fold increase in transaminase level is commonly encountered. The risk of fulminating hepatitis is less than 1/1000 but should always be entertained. All drugs should be stopped and careful research for recent xenobiotic contamination (drugs, infusions, alphamethyldopa, etc.) should be undertaken. Viral hepatitis requires serovaccination of the newborn at birth. Herpetic hepatitis is rare but requires rapid diagnosis (liver biopsy) and treatment with acyclovir in addition to cesarean section and treatment of the newborn at birth. Rare cases of hepatitis E may occur after a stay in North Africa, the Middle-East, Southeast Asia or Mexico. Chronic cases with or without temporary pruritus suggest infectious hepatitis B or C although, in chronic hepatitis C, serum transaminase levels often return to normal during pregnancy. Rare cases of asymptomatic elevations of serum transaminase levels can reveal subclinical chronic hepatitis.

We report the case of an 80-year-old woman with a previous history of HBP, hysterectomy due to cancer of the uterus and cholelithiasis, who was admitted in our hospital because of diffuse abdominal pain, marked jaundice, choluria and acholia during one week, together with anorexia and loss of weight. Blood chemistry results disclosed a total bilirubin of 11 mg/dl, a direct bilirubin of 8 mg/dl, GGTP 826 U/I, alkaline phosphatase 287 U/I, AST 285 U/I, ALT 837 U/I and LDH 242 U/I. The CA 19-9 marker was higher than 500 U/ml. The abdominal ultrasound examination did not show any space-occupying lesions; the extra and intrahepatic bile ducts were very dilated and the gall bladder showed multiple stones within its contents. The endoscopic retrograde cholangiopancreatography (ERCP) showed a homogeneous filiform defect at the middle third of the common bile duct of approximately 1 cm in length and with a marked dilatation of the bile ducts. A percutaneous drainage of the bile tree was performed, but the patient died.

Nineteen patients treated by continuous ambulatory peritoneal dialysis (CAPD) were studied according to clinical outcome parameters: insomnia, asthenia, pruritus, arterial hypertension, anorexia, nausea and/or vomiting, anemia, and rate of hospitalization. Using clinical scores, three groups were defined: poor clinical outcome (P), intermediate (I), and good (G). The quantity of treatment by PD was evaluated monthly with urea kinetic tests (weekly Kt/V, weekly urea clearance/1.73 m2 of body surface area (BSA), index of dialysis by Teehan), and with the weekly creatinine clearance/1.73 m2 of BSA. The metabolic index was analyzed: normalized protein catabolic rate (NPCR), serum albumin (Alb) and prealbumin, and reabsorption of glucose. There was good correlation between clinical scores and quantity of dialysis. The Alb was lower in group P. Group G was differentiated from group I and from group P by quantification tests and NPCR, with lower levels as follows: weekly Kt/V = 2.06, urea clearance 70 L/week/1.73 m2, index of dialysis = 0.87, and creatinine clearance = 60 L/week/1.73 m2. We conclude that the qualitative clinical approach is not sufficient to predict deleterious signs, and the quantitative approach is predictive of the good clinical outcome and good nutritional status. We think that levels proposed to now are insufficient, and we suggest the following: weekly urea clearance > 70 L, weekly Kt/V > 2, weekly creatinine clearance > 60 L, and index of dialysis > 0.85.

Our purpose in conducting this descriptive study was to assess the health-related concerns and experiences of a sample of employed perimenopausal women in Alexandria, Egypt. In addition, we explored their help-seeking behavior and their perception of symptoms. We interviewed two hundred working women ages 40-60 years, 42% of whom were nurses, using a semistructured interview form as well as Koos's list of symptoms. The commonly mentioned concerns, in order of frequency, were chronic headaches, chronic fatigue, transportation and phone communication problems, financial problems, job dissatisfaction, backaches, hypertension, kidney disease and gall bladder disease, gastritis/indigestion, menstrual disturbances, arthritis, AIDS, and hepatitis B. With respect to the problems experienced by the women in the past 6 months, there was a high self-reported prevalence of headaches, fatigue, transportation and communication problems, backaches, job dissatisfaction, dissatisfaction with health insurance, financial problems, menstrual disturbances, gastritis/indigestion, gall bladder disease, anxiety, disturbed sleep, and hypertension. Women attempted to manage their problems mainly by taking over-the-counter drugs and self-prescribing (75.5%), doing nothing or using traditional remedies (56.5%), and going to a doctor or health insurance office (40%). Symptoms perceived by the majority of the women as not needing medical attention included loss of appetite, persistent backache, bleeding gums, chronic fatigue, persistent headaches, and loss of weight. The influence of education and occupation on women's perceptions and practices is discussed.

Since its discovery in 1982, neuropeptide Y (NPY) has been shown to have numerous effects mediated by a growing number of NPY receptors in both the CNS and peripheral nervous system. Perhaps best appreciated is the role of NPY in the control of systemic blood pressure, together with its effects on feeding, anxiety and memory. However, recent evidence increasingly supports an important role for NPY in mediating analgesia and hyperalgesia by distinct central and peripheral mechanisms. In this review we concentrate on this important aspect of NPY pharmacology and consider mechanisms controlling the expression of NPY and its receptors. In addition, we also present the more recent data describing the other possible roles for NPY-NPY agonists and antagonists may be useful in the treatment of conditions as varied as anorexia, epilepsy, anxiety, depression, hypertension and heart failure.
