A case of intoxication in Southern Bulgaria after a bite from the venomous spider Latrodectus tredecimguttatus is reported. The development of both local (acute pain, itching erythema, paraesthesiae in the area of the bite) and general (weakness, headache, dizziness, fever, vomiting, myalgia, muscle cramps) symptoms, which passed relatively easily, is described. The clinical picture and treatment are briefly commented on.

A 44-year-old patient died from amyotrophic lateral sclerosis (ALS) after nine years of heavy exposure to cadmium (Cd) in a nickel cadmium (Ni-Cd) battery factory. Two years after starting work he and co-workers had experienced pruritus, loss of smell, nasal congestion, nosebleeds, cough, shortness of breath, severe headaches, bone pain, and proteinuria. Upper back pain and muscle weakness progressed to flaccid paralysis. EMG findings were consistent with motor neuron disease. Cd impairs the blood-brain barrier, reduces levels of brain copper-zinc (Cu-Zn) superoxide dismutase (SOD), and enhances excitoxicity of glutamate via up-regulation of glutamate dehydrogenase and down-regulation of glutamate uptake in glial cells. High levels of methallothionein, a sign of exposure to heavy metals, have been found in brain tissue of deceased ALS patients. The effects of Cd on enzyme systems that mediate neurotoxicity and motor neuron disease suggest a cause effect relationship between Cd and ALS in this worker.

A 50-year-old man had been well until three months earlier, when he felt general fatigue, and cutaneous rash with itching. Thereafter a general muscular weakness developed and the patient could not walk for a month. Four weeks before referral to our hospital, he had high fever and could not role over in the bed. On admission, the patient was able to walk. He had no skin rash. Neurologically, he showed mild weakness in proximal muscles. Hematologic examination showed mild eosinophilia and serum creatine kinase was mildly elevated. Needle electromyogram revealed a diffuse myogenic pattern in extremities. Eosinophilic myositis was diagnosed by a biopsy of the left calf muscle showing mild infiltration of eosinophilis which was identified using antibodies against eosinophilic granule protein.

The aim of the present study was to investigate baseline neurophysiological characteristics of the central and autonomous regulation and their reactivity to different tests in a group of persons with so-called 'electrical hypersensitivity', which is often considered as a form of psychosomatic disorders. Twenty patients with combinations of neuroasthenic symptoms (general fatigue, weakness, dizziness, headache) and facial skin (itching, tingling, redness) have been investigated. An equal number of symptom-free persons served as a control group. The examination comprised self-reported measures, testing of visual functions, measurements of blood pressure, heart rate and its variability, electrodermal activity, respiration, EEG and visual evoked potentials (VEP). Several variables were found to differ between the patient and the control groups. The mean value of heart rate in rest condition was higher in the patient group compared to the controls (mean value of inter-beat intervals were 0.80 and 0.90 s, respectively). Heart rate variability and response to standing test were decreased in the patient group compared to the controls. Patients had faster onset, higher amplitudes, and left-right hand asymmetry of the sympathetic skin responses. They had a higher critical fusion frequency (43 vs. 40 Hz), and a trend to increased amplitude of steady-state VEPs at stimulation frequencies of 30-70 Hz. The data indicated that the observed group of patients had a trend to hyper sympathotone, hyperresponsiveness to sensor stimulation and heightened arousal.

To explore the contextual factors influencing health-seeking behavior of women in Karachi regarding reproductive tract infections, 18 women with reproductive tract infections from different clinics and community settings were identified and in-depth interviews were conducted. Physicians in our study diagnosed a woman to have lower reproductive tract infection if she complained of malodorous vaginal discharge with or without perineal itching; and to have pelvic inflammatory disease or upper reproductive tract infection if she had any two of the following complaints: malodorous vaginal discharge, menstrual irregularities, lower abdominal pain or dyspareunia. Women consulted a variety of healthcare providers in their pursuit for treatment, mainly allopathic doctors and hakims. The different treatments prescribed to women ranged from oral and intravaginal medications to various home remedies including refraining from specific foods. Causes of reproductive tract infections reported were "melting bones", consuming foods with perceived hot composition, poor personal hygiene and procedures like dilatation and curettage, delivery and induced abortions. None reported sexually transmitted diseases as the perceived cause of their problem. Interference with religious activities, sexual relationships or socializing was reported as consequences of reproductive tract infections, in addition to lower abdominal pain, menstrual irregularities, backache and kamzori (weakness). Pakistani women seek care for reproductive tract infections and visit a variety of providers, though causes and treatments offered are usually not related to sexually transmitted diseases. We therefore suggest training of healthcare providers for appropriate counseling and that treatment management protocols be advocated.

Essential thrombocythemia and polycythemia vera are both chronic progressive myeloproliferative disorders of insidious onset. If the excessive production of red cells and/or platelets is controlled, patients with these disorders may have prolonged survival. However, the clinical course of these patients can be complicated by a variety of events, including thrombotic episodes, bleeding episodes, arthropathies, pruritus, weakness, weight loss, neurologic impairment, erythromelalgia, fever, abdominal pain, and the life-threatening consequences of progression to myelofibrosis and/or acute leukemia. Effective control of hematopoiesis by phlebotomy or a variety of therapeutic agents has resulted in a reduction or elimination of many of these clinical events, but has not altered the evolution to myelofibrosis or acute leukemia. Use of each of these therapeutic strategies is also associated with a range of adverse events. Monitoring overall survival or a reduction in the frequency of clinical events has previously served as a means of assessing the results of these therapeutic interventions. Quality-of-life instruments have not been applied in a systematic fashion to the evaluation of outcomes in patients with these chronic myeloproliferative disorders. Quality-of-life assessments evaluate not only the state of well-being of a patient that results from an assessment of the individual's ability to perform everyday activities, which are reflective of physical, psychological, and social well-being, but also patient satisfaction with the control of disease and/or treatment-related symptoms. Quality-of-life instruments have been used to assess the clinical course of patients suffering from a variety of disorders, ranging from cancer to renal failure to chronic fatigue syndrome. Information about quality-of-life outcomes can contribute to the evaluation of variations in dose and timing of administration of therapeutic agents. It is possible that the side effects of a particular therapy may outweigh the disease regression achieved with a particular therapy. In the future, quality-of-life instruments may prove useful in prospectively evaluating therapeutic end points in patients with essential thrombocythemia and polycythemia vera.

Three children developed human herpesvirus-6 (HHV-6), variant B encephalitis after unrelated umbilical cord blood transplant, in a single center. They developed clinical manifestations of encephalitis around day 17 post transplant. Impairment of consciousness, incoherent speech, episodic focal pruritus, motor weakness, convulsions and severe hyponatremia were features at presentation. Radiological investigation of brain ranged from unremarkable to extensive white matter and meningeal lesions. Diagnosis was established by the presence of HHV-6 DNA in cerebrospinal fluid (CSF). Retrospective analyses of plasma revealed the presence of viral DNAemia prior to the onset of disease in two subjects. Treatment with ganciclovir or foscarnet was given. Two subjects did not achieve engraftment and died of other transplant-related complications on day 38 and 56 post-transplant, respectively. One subject achieved disease-free survival for more than 1 year with a satisfactory neurological outcome. In conclusion, HHV-6 encephalitis is not uncommon among patients undergoing umbilical cord blood transplantation. It is worth conducting further studies on early diagnosis and optimal management of this potentially fatal disease.

Reactions to oral contraceptive therapy tend to be maximal during the first few months of use. They include nausea or epigastric discomfort, malaise, dizziness, nervousness, fatigue, weakness, leg cramps, headache, and depression. The estrogenic component is thought to be the cause. There may also be a psychogenic basis reflecting apprehension. Breast tenderness is an occasional complaint and intermenstrual spotting or breakthrough bleeding is often reported. Increasing dosage has reduced this symptom. Dysmenorrhea prior to treatment may be improved but occasionally it is aggravated. Drug-induced amenorrhea presents a double problem in that failure to resume medication 7 days after completion of a cycle results in a risk of conception. Episodes of severe uterine bleeding in patients discontinuing use after several months or years have been reported. Other side effects include a skin reaction resembling acne, pruritus, hirsutism, thinning of scalp hair, increased skin pigmentation, and weight gain or loss. Serious vascular complications and hepatic dysfunction have been shown and deviation of thyroid function may be shown by increase of serum protein-bound iodine (PBI). Clinical signs of hyperthyroidism have not been described. Oral contraception is associated with elevated plasma cortisol (hydrocortisone) levels and decreased urinary levels of 17-hydroxycorticosteroids (17-OCHS). Suppression of ovarian activity by oral contraceptives is rapidly reversible. Fear of carcinogenesis has caused much alarm but no proof as of the present time. Safety of long term use will require additional years of experience.

A May 1991 workshop on reproductive morbidity attended by 60 participants in Cairo included presentation of results of a study of 509 nonpregnant women aged 20-60 years. The study was conducted by an anthropologist, a biostatistician, 2 obstetrician-gynecologists, and a microbiologist in 2 rural villages of Gizeh. The majority of the women studied had married before age 19, and 80% were illiterate. Despite initial reticence, over 90% of the village women ultimately took part in the study. The team observed the frequency with which the women accepted illness, weakness, and pain as a normal part of life. Physical examinations revealed that 44% had vaginitis, 9% were anemic, 17% had severe anemia, 56% had prolapse, 18% were hypertensive, and 42% were obese. Survey questionnaires revealed that 36% experienced pain during intercourse, 18% had pain in the lower abdomen, 71% had menstrual pain, 15% had pruritus, and 48% feared they were sterile. The team observed that the women were apparently reluctant to use the local health services. The villages had their own health centers staffed by female physicians, but only 1/3 of the women giving birth in the preceding 2 years had sought prenatal care, and 75% chose to deliver at home. Relations between the health workers and the village women must be strengthened if the situation is to be improved. The seminar recommended that the health and social workers make greater efforts to encourage use of the health services by local women.

In Japan, there are many dialysis patients because of the successful development and wide application of dialysis techniques. Almost all patients require long-term hemodialysis treatment because kidney transplantation is performed rarely. Renal hyperparathyroidism is one of the serious complications for hemodialysis patients. According to the overview of regular dialysis treatment reported by the Japanese Society for Dialysis Therapy, parathyroidectomy is required in 9.2%of patients who remain on hemodialysis more than 10 years and in 33.5%of those who so remain for more than 25 years. In this paper, we will describe the diagnosis, surgical indications, and operative strategy of renal hyperparathyroidism. The symptoms and biochemical variables were high serum parathyroid hormone (PTH) level, hyperphosphatemia, bone and joints pain, itching, irritability, muscle weakness, severe skeletal deformity, progression of ectopic calcification, and anemia. The clinical indications for performing parathyroidectomy to treat renal hyperparathyroidism in our institute are based on the indications reported by Tominaga et al. These are 1) high serum PTH level, 2) detection of enlarged parathyroid glands, 3) detection of osteitis fibrosa cystica on radiography or detection of high bone turnover by bone metabolic markers or bone scintigram, 4) resistance of symptoms to medical treatment. The routine operative procedure for renal hyperparathyroidism is total parathyroidectomy with forearm autograft. For autotransplantation, 30 pieces sliced 1x1x3 mm of diffuse hyperplasia are implanted into 30 pockets in the forearm without arteriorvenous (A-V) fistula for hemodialysis. In any surgical procedure for renal hyperparathyroidism, it is crucial to identify all parathyroid glands, including supernumerary glands and ectopic glands. At the initial operation for renal hyperparathyroidism, the surgeon must remove all parathyroid glands to avoid persistent and recurrent hyperparathyroidism and choose proper and adequate parathyroid tissue for autograft.
