Side effects of chronic lithium therapy in Hong Kong Chinese: an ethnopsychiatric perspective.

A biocultural study of the side effects of chronic lithium treatment among 70 Hong Kong Chinese psychiatric patients, using a self-report 33-item checklist and semi-structured interviews, revealed an imperfect correspondence between biomedically prescribed and culturally endorsed psychotropic side effects. Although polydipsia and polyuria (47%) were the biomedically most 'real' side effects, they were not usually regarded as bothersome or translated into metaphors to express undesirable side effects. Complaints such as tiredness (38%), drowsiness (36%) and poor memory (31%) were also common but their frequency was significantly lower than that of normal control subjects. The item 'loss of creativity' had no conceptual equivalent in Chinese and was usually misinterpreted. As no patient was aware that lithium was a metal, the side effect 'metallic taste' was variously labelled. Contrary to Western findings, complaints of 'missing of highs', loss of assertiveness and fear of weight gain were rarely encountered. Active elicitation was required for indigenous complaints, with 38% of patients considering lithium to cause mild "hotness." This was readily neutralized by drinking more water which had a "cooling" effect. Expectedly, concurrent neuroleptics and antidepressants amplified most lithium side effects. This study affirms Western data on the biomedically universalizable effects of chronic lithium treatment, but also supports the thesis that culturally constituted cognitive styles affect patients' recognition, labelling, experiencing and reporting the total drug effect. Further, it demonstrates that the lived experience and clinical negotiation of lithium associated side effects reproduce, authenticate, and at times critique, core cultural and moral premises of Western and Chinese societies.

Sodium loss as leading symptom of renovascular hypertension in the newborn.

The history of a newborn developing severe renin-induced hypertension is reported. A thrombotic occlusion of the lower a.abdominalis with an ascending thrombus into the left a.renalis caused hypertension according to the two-kidney-one-clip hypertension. High pressure diuresis induced weight loss by polyuria, hyponatremia and hypokalemia by severe renal salt losses. The vicious circle of malignant hypertension was initiated by sodium losses, not sufficiently recompleted by therapy. The full picture of an acute hypertensive renal damage was seen at autopsy in the unclamped kidney.

Primary aldosteronism due to adrenal carcinomas.

In the present study two patients with aldosterone-producing adrenal carcinomas are reported. The clinical features were characterized by hypertension and severe hypokalemia with muscular weakness, flaccid paralysis of arms and legs, diarrhea and polyuria. In both cases excessively high plasma aldosterone levels and suppressed plasma renin activity were found. In contrast to most other cases with aldosterone-secreting tumours plasma cortisol, urinary free cortisol excretion, 17-hydroxy- and 17-ketosteroids were in the normal range. There was no clinical evidence of oversecretion of sex hormones. After adrenalectomy blood pressure and serum potassium normalized and the clinical symptoms disappeared. Plasma aldosterone and urinary aldosterone secretion returned to normal, while plasma renin activity remained low. Three and a half and 6 months later primary aldosteronism and the associated clinical symptoms reappeared due to hormonally active metastases. After introducing the antitumour drug o,p'-DDD in patient 1 aldosterone secretion normalized and the clinical status of the patient markedly improved. However, 10 months after diagnosis the patient died due to a haemorrhage from a liver metastasis. In patient 2 tumour-invaded regional lymph nodes were surgically removed with only minor changes in the hormone pattern.

Severe hyperprostaglandin E syndrome with hyperthyroidism--studies of pathogenetic mechanisms.

Hyperprostaglandin E syndrome is a rare disease usually presenting with renal symptoms such as polyuria, polyhydramnios, hypercalciuria, hypokalaemia, and recurrent episodes of extreme fever, diarrhoea, and convulsions. We report a severe variant of this syndrome with obvious pain and prostaglandin E2 (PGE2)-stimulated hyperthyroidism, an association not previously described. Urinary excretion of PGE2 and its metabolite 7 alpha-hydroxy-5,11-diketotetranorprosta-1,16-dioic acid were markedly increased above normal levels (to 53.3 and 1895 ng/h per 1.73 m2, respectively). We studied oxidative capacity of peroxisomes and mitochondria, the sites where PGE2 oxidation takes place. A generalized mitochondrial disease could be ruled out and no deficiency was found in liver peroxisomal oxidases. The basic pathology of hyperprostaglandin E syndrome remains unsolved.

Pituitary granuloma and chronic inflammation of hypophysis: clinical and immunohistochemical studies.

We describe five patients with chronic inflammation of the hypophysis including three pituitary granulomas of unknown aetiology. In contrast to the previously reported cases, the involvement of neurohypophysis or hypothalamus was a distinct clinical feature in these patients. Impairment of anterior pituitary function was less prominent, while polyuria and polydipsia occurred in all cases. Enlargement of the sella turcica was absent in three and slight in two cases. CT scan and MR images demonstrated a contrast-enhanced sellar mass in all patients; abnormally thickened pituitary stalk and infundibulum with contrast-enhancement was observed in four. The fibrous tissues were removed by the transsphenoidal approach in four patients, and by the subfrontal approach in one case. In all patients, the endocrinological dysfunction was prolonged. No increase in the size of the remaining pituitary mass was demonstrated on repeated MR images in any of the patients. On histological examination, granulomatous formation was present in three samples, and multinucleated Langhans' giant cells were seen in one. The epithelioid cells and multinucleated giant cells constituting the granulomas were positive for anti-macrophage antibody. No firm laboratory or histological evidence was obtained supporting the presence of systemic disease leading to granulomas. In the other two cases, the pituitary lesions were composed of chronic inflammation tissue, and serum antipituitary antibodies were present in a patient with concurrent Hashimoto's thyroiditis. Our experiences with chronic inflammation of the hypophysis indicate that these patients are best managed by histological confirmation of the lesion followed by adequate hormonal replacement.(ABSTRACT TRUNCATED AT 250 WORDS)

Atypical presentation of multisystem disorders in two girls with mitochondrial DNA deletions.

UNLABELLED: We describe two girls with atypical presentations of multisystem disorders due to deletions in mitochondrial DNA (mtDNA). One presented with painful carpopedal spasms due to hypoparathyroidism at the age of 4 years. The disease was rapidly progressive with development of truncal and limb ataxia, spastic paraparesis, muscle weakness and wasting, pigmentary retinal degeneration and sensorineural hearing loss. She had short stature and vitiligo patches, hirsutism, anaemia, diabetes mellitus and exocrine pancreatic dysfunction. The other girl presented at the age of 6 years with polydipsia, polyuria and fatigue due to renal tubular dysfunction. The disease was insidiously progressive with poor growth and development of sensorineural hearing loss, muscle weakness and truncal and limb ataxia. Morphological, enzyme histochemical and biochemical investigations indicated mitochondrial dysfunction of skeletal muscle, liver and kidney in one patient and of skeletal muscle and liver in the other. Both patients had large proportions of mtDNA molecules with deletion in liver, kidney, skeletal muscle and blood cells. CONCLUSION: It may be concluded that symptoms from several different organs may be the first manifestation of a mtDNA deletion disorder.

Nephrotoxicity of sodium dichromate depending on the route of administration.

A comparison of the effects of intraperitoneal and subcutaneous routes of administration of sodium dichromate on nephrotoxicity in rats was studied. Dichromate when injected subcutaneously (SC group) produced a higher degree of nephrotoxicity than when administered intraperitoneally (IP group). It caused severe progressive proteinuria followed by polyuria and glucosuria, reaching maximum levels at 3 days after treatment in the SC group, whereas it produced mild proteinuria without glucosuria in the IP group. The dose-dependent increases in blood urea nitrogen (BUN) and creatinine concentrations, shown in the SC group, were not observed in the IP group. However, between the two groups, there were no great differences in either the urinary excretion rate of chromium or the electrophoretic patterns of urinary protein in the day 1 urine specimens. Pretreatment of phenobarbital (PB) had no remarkable effect on the dichromate-induced nephrotoxicity. In contrast, it potentiated dichromate-induced hepatotoxicity, the indices of which were the elevation in serum alanine aminotransferase (ALT) activity and hepatic lipid peroxide formation. These results suggest that the dependence of dichromate-induced nephrotoxicity on the route of administration is related to the chemical forms of chromium reaching the kidney, and the necrotizing property of dichromate results from its metabolic fate in vivo.

Enzootic haematuria in Nepal.

Haematuria of cattle has been recognised in the Nepal hills for many years where it is of local economic importance. The aetiology has been thought to be babesiosis. The disease was investigated in East Nepal over a nine month period. Affected animals exhibited a chronic, intermittent haematuria and an associated polyuria and dysuria. The average age of onset of clinical signs was 7.3 years and duration 1.5 years. Investigation revealed that urine samples contained intact red blood cells, protein and white blood cells. Red blood cell counts, packed cell volume and haemoglobin concentration were not significantly reduced compared to unaffected cattle. Histopathological examination of abnormal bladder tissue revealed epithelial proliferation and mononuclear infiltration and large, blood filled cavities in the lamina propria. Pteridium aquilinum, bracken fern, is common in this area. Blood smears were negative for Babesia spp. These findings conform to the classical description of enzootic haematuria. This is the first recorded occurrence for Nepal.

Addison disease 10 years after bone marrow transplantation for Wiskott-Aldrich syndrome.

UNLABELLED: We report a 10-year-old boy with familial Wiskott-Aldrich syndrome (WAS) who underwent successful bone marrow transplantation (BMT) at the age of 9 months. With the exception of auto-immune haemolytic anaemia due to warm antibodies lasting 15 months there had not been any complication after BMT. Ten years later the patient presented with diarrhoea, hyperpigmentation of skin and oral mucosa, fatigue and polyuria. Diagnosis of Addison disease was confirmed by typical electrolyte imbalance and absent cortisol response to adrenocorticotrophic hormone. Adrenal antibodies were positive. On therapy with oral gluco- and mineralocorticoids, the symptoms disappeared and electrolytes normalized. To our knowledge auto-immuno endocrinopathy after BMT for WAS has not yet been reported. CONCLUSION: This is the first report of auto-immune adrenal insufficiency after BMT for WAS. The aetiopathogenesis of this condition remains unknown since auto-immune diseases as toxic side-effects of the ablative treatment before BMT have not yet been reported, and a relapse of WAS and cotransplantation of auto-immune adrenal insufficiency have been ruled out.

Transplantation of preserved pancreatic islets into the portal vein of rats.

Langerhans islets were isolated from the exocrine pancreata of Wistar rats by the improved collagenase-digestion method. The isolated islets were preserved in a tissue culture medium for seven days. Transplantation of these preserved islets into the portal vein of streptozotocin-induced diabetic rats resulted in a significant reduction of hyperglycemia, polyuria and glucosuria, and a restoration of weight gain. It was found that these effects could be maintained for 16 weeks. In order to normalize the K-values and plasma insulin levels, at least 600 islets had to be transplanted into each diabetic rat.

Acute self-poisoning with phenformin.

The case is reported of a non-diabetic young woman who attempted suicide by ingesting 2,500 mg of phenformin. The most marked clinical and laboratory findings during the first 24 hrs included nausea, vomiting, anxiety, agitation, polydipsia, polyuria, increased appetite, tachycardia, tachypnea, persistent lactic acidosis, hypoglycemia and hypokalemia. Treatment at the ICU 10 hrs after ingestion of the overdose was essentially symptomatic and included measures to correct acidosis and hypoglycemia. The patient recovered completely.

Nocturnal enuresis.

Childhood enuresis is a common socially disruptive problem. The possible pathophysiological factors include a disorder of sleep arousal, nocturnal polyuria, and low bladder capacity. The evaluation of a patient with nocturnal enuresis is aimed to exclude any organic pathology, UTI and voiding dysfunction. An approach to management of this common disorder is outlined.

Hyponatraemia and hypovolemic shock with tuberculous meningitis.

A 12-year-old boy with tuberculous meningitis and hydrocephalous, after undergoing revision of ventriculo-peritoneal shunt had persistent impairment of sensorium and episodes of hyponatremia (serum sodium 104 to 125 mmol/l), accompanied by polyuria, signs of poor peripheral, perfusion hypotension and low CVP, and high urinary sodium excretion (114-60 mmol/l). A diagnosis of cerebral salt wasting syndrome (CSWS) was made and was treated with saline replacement and fludrocortisone (10 microg/kg/day). Within next 3 days the sensorium, signs of shock, urine output and serum and urinary sodium returned to normal. The case illustrates that life-threatening hyponatremia in a child with neurological illness could be caused by CSWS, which must be differentiated from Syndrome of inappropriate antidiuretic hormone secretion (SIADH), as CSWS requires rigorous salt and volume replacement in contrast to fluid restriction in SIADH.

Diabetes mellitus in newborns and infants.

Diabetes mellitus is uncommon in infancy and newborn period. The two common forms seen are the transient and permanent forms of diabetes mellitus of the newborn. They have to be differentiated from the transient hyperglycemic states (Blood sugar > 125 mg/dl) seen in newborns who receive parenteral glucose infusions and in those with septicemia and CNS disorders. Transient diabetes mellitus of the newborn (TDNB) is defined as hyperglycemia occurring within the first month of life lasting at least 2 weeks and requiring insulin therapy. Most of these cases resolve spontaneously by 4 months. It has a reported incidence of 1 in 45,000 to 60,000 live births. The most likely etiology is a maturational delay of cAMP mediated insulin release. The clinical features include small for datedness, proneness for birth asphyxia, open-eye alert facies, dehydration, emaciation, polyuria and poydipsia. These children are prone to septicemia and urinary tract infections. They have hyperglycemia, glucosuria, absent or mild ketonuria, low basal insulin, C-peptide and IGF-1 levels. Treatment consists of hydration and judicious administration of insulin with close monitoring. Thirty percent of these children are likely to develop permanent neonatal diabetes. Compared to transient form, permanent diabetes mellitus is uncommon. It is usually due to pancreatic dysgenesis often associated with other malformations and rarely due to type 1 diabetes mellitus. The diagnosis is based on the demonstration of both exocrine and endocrine pancreatic dysfunction. These children are managed as type 1 diabetes mellitus. They are prone to develop the vascular complications of diabetes at an earlier date.

Relationship between the clinical features and the viral antigen in the extremity blood of the patients with hemorrhagic fever with renal syndrome.

The direct immunogold silver staining (D-IGSS) method was used to detect the viral antigen in the extremity blood of 67 cases of hemorrhagic fever with renal syndrome. The positive rate of viral antigen was the highest during the fever, hypotension and oligouria phrase; and the rate dropped gradually during the polyuria and convalescent phase. It is suggested that clinical staging was positively related with the percentage of the viral antigen positive cells (P < 0.001). It is concluded that the positive rate was related to the extent of the injuries by direct viral attack and immune reaction. The D-IGSS was proved to be fast, simple, economical, with high sensitivity and specificity.

Tissue injury and proliferative response induced in rat kidney by cis-diamminedichloroplatinum (II).

Cis-diamminedichloroplatinum (II) (cisplatin), an inorganic platinum salt used in cancer chemotherapy, is characterized by a renal toxicity recognized both in experimental animals and in patients treated with the compound. The purpose of the present study was to explore by both light and electron microscopy the morphological alterations induced in the rat kidney by cisplatin administration and, in particular, to analyse the tissue repair reaction following nephrotoxic injury. Experimental animals (four rats per group) were treated i.p. with 2, 4 or 8 mg/kg cisplatin administered in four consecutive daily injections. The rats were sacrificed 4 days after the last injection. In addition, the persistence of renal lesions and the duration of the repair reaction were determined in rats given 8 mg/kg cisplatin and killed 4, 7, 14 or 21 days after the last injection. The cell proliferation associated with tissue repair was estimated both quantitatively (rate of DNA synthesis) and qualitatively (histoautoradiography and electron microscopy examination) 1 h after in vivo exposure to [3H] thymidine. Renal tissue alterations and the repair reaction were minimal after the administration of 2 or 4 mg/kg cisplatin. In contrast, 8 mg/kg cisplatin caused a spectrum of morphological abnormalities affecting proximal, distal and collecting tubules, and ranging from sublethal cell alterations to tubular necrosis and cystic dilatation. The latter degenerative change primarily involved the straight portion of proximal tubules and seemed to develop over the weeks following cisplatin administration. Concomitantly with the tissue lesions, a burst of cell proliferation, associated with stimulation of DNA synthesis, was apparent in the renal cortex and outer medulla. Whereas a very high incidence of S-phase cells was encountered in seemingly undifferentiated tubules, they also appeared in differentiated proximal, distal and collecting tubules, but were infrequent in cystic tubules. Proliferation of fibroblasts was also stimulated in the renal interstitium. The proliferative response persisted for the whole duration of the experiment, indicating incomplete tissue repair. The long-lasting tubular injury and the slowness of repair are consistent with the chronic renal dysfunction (polyuria and hypomagnesemia) that cisplatin is known to induce in both man and experimental animals.

[The conformal radiotherapy of localized prostatic carcinoma: acute tolerance and early efficacy].

AIM: In a prospective trial early effectiveness and acute toxicity of conformal 3D-planned radiotherapy for localized prostate cancer was quantified using dose-volume-histogramms and evaluated with respect of treatment technique. PATIENTS AND METHOD: Thirty-two men (44 to 80 years old) with locally advanced carcinoma of the prostate (stage B2 or C) have been treated by 3D-planned conformal radiotherapy using high energy photons. In 28/32 men treatment technique was a monoaxial bisegmental rotation with irregular fields. With single doses of 2.0 Gy a mean total dose of 63.9 +/- 4.9 Gy according to ICRU was applied within 46 +/- 4 days. Maximum dose was in the mean 105.1% +/- 3.8%. 3D treatment volume was 274.1 +/- 113.4 cm3. Median follow-up is 1.8 years (15 to 34 months). Toxicity was evaluated according to RTOG-EORTC by patient interview and physical examination on a weekly basis during radiotherapy and by regular follow-up. RESULTS: Eleven patients had none, 15 mild (RTOG grade 1) and 6 moderate symptoms (RTOG grade 2, mainly diarrhoea, dysuria and polyuria). Acute complications leading to treatment interruption did not occur. In 16 patients symptoms disappeared within 6 weeks after radiotherapy. Only 2 men had symptoms which lasted longer than 3 months and were endoscopically examined. Up to now no late complications were detected. Incidence and severity of toxicity was significantly (p < 0.05) related to the size of treatment volume. Acute toxicity was found to depend statistically significant (p < 0.05) on the proportional volume of bladder and rectum, irradiated with more than 35 Gy. In 81% of the patients with pretherapeutic elevated PSA levels normalisation of PSA was observed. Overall mean PSA levels of 15.7 +/- 22.6 micrograms/l at the beginning of radiotherapy fell to 2.1 +/- 3.7 micrograms/l 6 weeks after irradiation. Only 1 Patient relapsed locally 22 months after radiation therapy. CONCLUSION: We conclude that due to modern 3D-planned conformal techniques with optimization of treatment dose and improved protection of critical organs such as urinary bladder and rectum, radiotherapy allows an effective and well tolerated therapy of localized prostatic carcinoma.

[The unmasking of secondary adrenal insufficiency and central diabetes insipidus by a highly febrile acute Hantaan virus infection].

CASE REPORT: A 32-year-old obese patient was admitted to our hospital as an emergency with very severe abdominal pain. Routine examinations initially failed to establish a diagnosis. The patient then went on to develop a high fever that was associated with polydipsia and polyuria. Serological studies revealed an acute infection with the Hantaan virus. Laboratory investigations showed hypofunction of the anterior and posterior lobes of the pituitary, with complete absence of ACTH, which was caused by two germinomas located intracranially. CONCLUSION: The clinical symptoms had thus been the result of acute secondary insufficiency of the adrenal cortex, which was unmasked by the acute, highly febrile Hantaan viral infection.
