Organic, physiologic, and psychologic causes of dysmenorrhea are presented. Signs and symptoms include pelvic fullness, nausea, vomiting, diarrhea, urinary frequency, nervousness, and headaches. Primary dysmenorrhea has been treated with analgesics, diuretics, and antispasmodics. Androgen therapy was also found to be effective, but it cannot be used for women who have acne or hirsutism. Surgery is rarely indicated for primary dysmenorrhea.

A case report of mesenteric venous thrombosis with small bowel infarction in a 38-year-old woman who had been taking oral contraceptives is reported. The patient was admitted complaining of severe abdominal pain and vomiting for 36 hours. On admission, temperature was 37.5 degrees C and pulse 120/minute. Abdominal rigidity and left-sided abdominal tenderness were present. X-ray of the abdomen showed 2 distended loops of small bowel and 3 fluid levels. Serum amylase was normal. White cell count was 10,000/cu mm. There was a history of abdominal pain and diarrhea over a period of several years. For 6 months she had been taking Ovulen (mestranol .1 mg and ethynodiol diacetate .5 mg) for menstrual irregularity. 2 weeks earlier she had suffered an influenzalike illness with pleuristic chest pain, loin pain, urinary frequency, and dysuria. Chest X-ray and intravenous pylography were then reported as normal. At immediate operation, a 15 cm segment of ileum was found to be infarcted. Semipurulent fluid was present in the abdomen and areas of fibrinous peritonitis were observed. The involved segment of ileum was resected. A small thrombus was extracted from a mesenteric vein. Initial postoperative course was good but 3 days after operation chest pain, dyspnea, and giddiness developed and cardiac arrest followed. Resuscitation was successful. Pulmonary angiography then showed thrombi in all branches of the pulmonary artery. After heparin therapy symptoms improved and the patient left the hospital in 2 weeks, her condition being stabilized with warfarin and dipyridamole (Persantin). The diagnosis was confirmed by histological examination. Early recanalization of a mesenteric vein was noted. Other reported cases have shown an average prodromal phase of 4 or 5 days. The long-term diarrhea was considered as not connected with the present illness but the presumed influenza illness 2 weeks earlier may have been due to a pulmonary embolism. Of reported cases, 5 of 13 have died. Early diagnosis, prompt surgery, and heparin therpay are considered important.

From January 1981 to December 1987, 346 children with urinary tract infections, proved by urine culture, were admitted to the Department of Pediatrics, Mackay Memorial Hospital. The ratio of male to female was 3.0 in children below 2 years, and 0.8 in children above 2 years, of age. The urine specimens were collected from suprapubic punctures in 281 cases (81.2%). Fever was the most common clinical manifestation. In children below two years old, other common symptoms and signs were body weight loss or poor gain, feeding problems, diarrhea, irritability, jaundice, and abdominal distension. In older children, urinary frequency, dysuria, enuresis, loin and abdominal pain were frequently found. Hematuria and edema were occasionally noted in all age groups. Microscopic examination of 329 centrifuged urine specimens revealed: 256 cases (77.8%) had more than 5 leukocytes per high power field, 233 cases (70.8%) had more than 10 leukocytes. Three hundred and seventy positive urine cultures were obtained from these patients. E. coli was isolated in 273 cases (73.6%), followed by Klebsiella spp., 34 cases (9.2%); Proteus spp., 27 cases (7.3%); Enterococcus, 21 cases (5.7%); Enterobacter spp., 9 cases (2.4%); Pseudomonas aeruginosa, 8 cases (2.2%); Citrobacter spp., 7 cases (1.9%); Morganella morganii, 6 cases (1.6%); Acinetobacter spp., 6 cases (1.6%); etc. Candida albicans was isolated from three patients. Two organisms were isolated in 26 cultures; 3 organisms, in 3, and 4 in 1.

In recent years, lower serum levels have been recommended for maintenance therapy with lithium. We studied 94 patients with bipolar disorder in a randomized, double-blind, prospective trial of two different doses of lithium for maintenance therapy: the "standard" dose, adjusted to achieve a serum lithium concentration of 0.8 to 1.0 mmol per liter, and a "low" dose, resulting in a serum concentration of 0.4 to 0.6 mmol per liter. The group medians of the patients' average serum lithium levels were 0.83 mmol per liter for the patients in the standard-range group and 0.54 mmol per liter for those in the low-range group. Six of 47 patients (13 percent) assigned to receive lithium doses that would produce serum levels in the standard range had relapses while on protocol, as compared with 18 of 47 (38 percent) assigned to the low-dose range. The risk of relapse was 2.6 times higher (95 percent confidence interval, 1.3 to 5.2) among patients in the low-range group than among those in the standard-range group. Side effects, including tremor, diarrhea, urinary frequency, weight gain, and a metallic taste in the mouth, were more frequent in the standard-range group. We conclude that doses resulting in serum lithium levels from 0.8 to 1.0 mmol per liter are more effective in treating bipolar disorder than those that result in lower serum lithium concentrations, although the higher doses are associated with a higher incidence of side effects. Recent findings about the limited nephrotoxicity of lithium, along with our observations, suggest that physicians should attempt to maintain serum lithium levels between 0.8 and 1.0 mmol per liter in most patients with bipolar disorder and that they should attempt to enhance patients' understanding of and compliance with this regimen.

A patient with several weeks of diarrhea developed for the first time severe urinary frequency and urgency and was admitted with acute urinary retention. Imaging techniques showed a large mass compressing the posterior wall of the bladder adjacent to the rectosigmoid colon, leading to a bilateral dilatation of the ureters. Cystoscopy and biopsy of the affected part of the bladder showed no tumor but a nonspecific acute inflammation. After identification of trophozoites of Entamoeba histolytica in the stool and confirmation by colonoscopy, barium enema, and serology of acute amebic colitis, the patient was treated with metronidazole. Urinary symptoms immediately resolved with a complete disappearance of the mass and a later cure of the colitis. This is a first report of severe urinary symptomatology dominating the clinical picture in amebic colitis, due to compression of the urinary bladder by an ameboma.

Clinical effects of oxybutynin hydrochloride on lower urinary tract function at a dosage of 2 mg given orally three times daily (6 mg/day), were studied on 10 patients with neurogenic bladder by cystometry and measurement of residual urine. There was a significant increase, of about 34% in FDV, but no significant changes in MBV, or maximum voiding pressure of residual urine after administration. Urinary frequency, incontinence and urgency in subjective symptoms were decreased in patients given this drug. The effective rate (excellent and good) was 50% in global evaluation. Side effects were observed in 4 out of 10 patients; 3 had dry mouth and 1 had diarrhea. There were no serious side effects. These findings suggested that oxybutynin hydrochloride may be a useful drug for neurogenic bladder.

Dimethoate, an organophosphorus insecticide, was the suspected cause of toxicosis in a group of young cattle grazing on pasture that had been sprayed 6 weeks before the onset of clinical signs. Affected animals had primarily nicotinic signs, such as muscle twitching, stiffness, weakness and paralysis, though muscarinic signs, such as diarrhea, salivation and pollakiuria, were also observed. Whole blood acetylcholinesterase activity was depressed in 3 animals. The atypical clinical syndrome and poor response to treatment with atropine and other anticholinergics may have been due to coexistent hypomagnesemia.

Clinical study of HCFU for head and neck cancer was performed HCFU at a daily dose of 600 to 900 mg. Was orally administered to 30 patients, including 5 patients with metastases. The primary sites of cancer were: larynx 9 cases, mesopharynx 6 cases, hypopharynx 5 cases, maxilla 5 cases, nasopharynx 3 cases, parotid gland and floor of the mouth one each. All of them were squamous cell carcinoma except a case presenting parotid lesion caused by adenocarcinoma. In 7 cases receiving the single therapy of HCFU for one month, a positive response was presented in one out of 7. Twenty-three cases treated HCFU in combination with radiation, 11 showed complete response (CR: over 90% decrease of tumor size), 6 showed partial response (PR: over 50% decrease), 3 showed minor response (MR: over 25% decrease), and 3 were diagnosed as no change (NC). Positive responses evaluated as PR or above obtained at the mean cumulative dose of 25.7 Gy and HCFU 15972 mg. Four cases receiving HCFU in adjuvant chemotherapy were studied only for clinical toxicity. Clinical toxicities of HCFU in 30 patients were presented in transient pollakiuria (7 cases), neurotoxic effect (2), eruption and diarrhea (one each). Symptoms similar to anemia and unconsciousness caused by the intake of alcohol were found in 6 patients. Although positive effect of HCFU was observed only in one case being administered singly, it presented better results in more cases when administered in combination with radiation. The combination therapy also made the lesions respond faster than by radiation therapy only. Intake of any alcohol is not advisable.

A phase I study of a new fluorinated pyrimidine, 1-hexylcarbamoyl-5-fluorouracil (HCFU), was performed by a multi-institutional clinical study group using a total of 111 patients with histologically proven malignancies. The characteristic toxic effects were a transient hot sensation and pollakiuria, which occurred 15-120 minutes after oral administration of the drug, continued for 30 minutes to 4 hours, and subsided spontaneously. Gastrointestinal disturbances such as nausea, vomiting, diarrhea, and anorexia, which are common with 5-FU administration, also occurred with HCFU but did so less frequently. The maximum tolerated dose for a single oral administration was estimated to be between 12 and 15 mg/kg and the optimal daily dose for continuous administration was considered to be between 9 and 18 mg/kg, with divided daily administration. Fifty-seven patients received 5-19 mg/kg/day of HCFU for > 4 weeks, including 31 patients with > 60 days' treatment. Cumulative doses were from 9.5 to 166.2 g, with a mean of 26.3 g. Hematopoietic toxicity was slight and hepatic toxicity was questionable. No renal or other cumulative toxicity was observed. In ten of the 57 patients, favorable clinical effects were seen: an active decrease in the size of the solid tumor (three patients), the disappearance of ascites (six), and the improvement of intestinal obstruction due to peritoneal carcinomatosis (one).
