A rare case is reported of pineal metastasis from lung cancer initially caused by neurological abnormalities of pineal tumor. A 70-year-old female suffering from headache and deterioration of consciousness for 1 week was admitted. She also had a tumor on both sides of her neck. On admission, neurological examination revealed disturbance of upward gaze, and CT scans showed hydrocephalus and pineal tumor. The tumor was seen as a slightly high density mass on non-contrast CT, and was homogeneously enhanced after administration of contrast material. Right V-P shunt and excision of the left neck tumor were performed at the same time. Pathological diagnosis of neck tumor was undifferentiated carcinoma metastasized to cervical lymph nodes. Extensive study was made, by bronchial fiberscope and biopsy, in order to find the origin of the malignancy and disclosed a small cell lung cancer of left lower lobe. The patient took radiation therapy for both the whole brain (60 Gy) and for the bilateral cervical regions (45 Gy). Two courses of chemotherapy using CDDP, ADR, VCR and CY were administered. Both the neck and the pineal tumors were markedly reduced in size at the termination of radiation therapy. However, she was readmitted 3 months later because of dyspnea. Chest X-P revealed enlargement of the left-lung tumor. She died on April 22, 1987. General autopsy disclosed invasive enlargement of left lung cancer, however, no remote metastasis was found. Examination of pineal region showed only necrotic pineal tissue, and no tumor cell was seen in either macroscopic or microscopic study.(ABSTRACT TRUNCATED AT 250 WORDS)

Atenolol, a cardio selective beta-adrenergic blocker, frequently prescribed in various cardiac ailments, has not been thoroughly investigated for its adverse reaction profile in Indian patient. The present ADR monitoring study which was open, prospective and collaborative was therefore planned. A total of 440 patients with various heart disease were enrolled after a strict inclusion and exclusion criteria from Maulana Azad Medical College, New Delhi and J.N. Medical College, Aligarh. fifteen patients dropped out leaving 435 for final analysis. Cold extremities occurred in 1.18% headache and dizziness in 1.41% breathlessness in 0.94% oedema in 0.70% and bradycardia in 0.47%. Adverse drug reaction in our study were less than those reported from Western countries. Better patient selection, optimal dose could have reduced the frequency of ADR in the present study. Racial factor and season might be operating to bring down ADR to atenolol in Indian patients.

Propranolol, a nonselective beta-adrenergic blocking agent, although prescribed frequently, has not been monitored for its adverse reactions in Indian population. A collaborative ADR monitoring study was planned in 2661 hypertensive patients. Exclusion criteria were associated circulatory insufficiency, heart block, left ventricular failure, diabetic mellitus and airway obstruction. The incidence of ADR was 2.1%, which is lower than reported incidence of 8.7 to 43.7 percent in other studies. This could be attributed to improper selection of patients, differences in methodology of monitoring, or to racial variation. In the present study ADR of fatigue (1.1%), dizziness (0.4%) and headache (0.2%) constituted the bulk. Additional reaction of pain in chest (0.2%), heart block (0.1%), hypoglycemia (0.1%), loss of libido (0.1%) and shock (0.03%), were also observed.

This paper reviews the safety data for levofloxacin utilizing reports from clinical and post-marketing surveillance trials. The side effect incidence rates are 1.3% for nausea, 0.1% for anxiety, 0.3% for insomnia, and 0.1% for headache. No levofloxacin-related adverse events were reported at a rate higher than 1.3%, and most were lower. Four clinical trials were reported. Levofloxacin achieved superior clinical and microbiological results compared to ceftriaxone/macrolide combination, and was better tolerated. Results comparing IV azithromycin plus ceftriaxone versus 500 mg levofloxacin in hospitalised CAP demonstrated that levofloxacin performed better, with more adverse events associated with the comparators (levofloxacin 5.3%, comparators 9.3%). High-dose levofloxacin (750 mg) was also evaluated and found to be well tolerated. Surveillance data reported low ADR rates for levofloxacin: nausea 0.8%, rash 0.5%, abdominal pain 0.4%, and diarrhoea, dizziness, and vomiting 0.3%. Worldwide and US surveillance data confirmed that tendon rupture occurred in less than 4 per million prescriptions, taste perversion in less than 3 per million, convulsions in 2 per million, and photosensitivity, hepatitis, hepatic failure, QT prolongation, torsade de pointes or empyema all in less than 1 per million.

Pseudotumor cerebri (PTC) is a rare neurological disorder characterized by increased intracranial pressure in absence of any intra-cranial space-occupying lesion. It is mostly due to impairment of drainage of CSF from arachnoid villi. Clinically pseudotumor cerebri presents with headache, diplopia, nausea, vomiting, papilloedema and if treatment is delayed, may lead to blindness. Females of childbearing age group, endocrinal abnormalities and ingestion of certain drugs have been reported to be associated with pseudotumor cerebri. However, it's occurrence in relation to acitretin ingestion has not been reported on pubmed database. Here we present a case where significant temporal association of acitretin intake with PTC was found in a child who was being treated with this medication for recalcitrant pustular psoriasis. The case is reported for its rarity in occurrence and associated significant morbidity including visual loss if not diagnosed and treated immediately. According to Naranjo ADR Causality scale of adverse drug reaction, the association of PTC due to acitretin in our case was probable.

Male erectile dysfunction is common and frustrating after the age of forty years. Erectile dysfunction is a cause of misery, relationship difficulties, and significantly reduced quality of life. Sildenafil citrate (Viagra) has shown promising results in recently published clinical trials. Sildenafil is a potent and competitive inhibitor of cGMp specific phosphodiesterase-5, predominant isoenzyme in the human corpus cavernosum. It is effective in erectile dysfunction of diverse origin, however it requires a patent vascular system to be effective. It is not effective in patients with endocrinal impotence, loss of libido, premature ejaculation or infertility. Its main adverse effects are headache, flushing, dyspepsia, diarrhoea, nasal congestion, indigestion, visual disturbances, dizziness and rash. Ventricular tachycardia and acute myocardial infraction have been reported in patients of ischaemic heart disease after consumption of sildenafil. Six deaths have been reported in patients taking nitrates. In India it is likely to be prescribed by a primary care physician without complete evaluation of patient on complaint of impotence. Hence the ethical question of who should prescribe this drug should be addressed by medical fraternity and proper guidelines formulated to avoid misuse of sildenafil. Phosphodiesterase is distributed in nerve, central nervous system, and systemic vasculature, hence long-term effects of drug on these tissues has to be ascertained. It should be made mandatory to report all adverse drug reactions to ADR monitoring centres. It is a wonder for those who require it, but has potentially dangerous adverse effects and drug interactions and hence is and not a wonder pill for all kinds of impotence.

In order to understand the characteristics of adverse drug reaction/adverse event(ADR/AE) of Ginkgo biloba Dropping Pills and evaluate the safety of clinical use after marketing, 407 ADR/AE case report data of Ginkgo biloba Dropping Pills collected by National Center for ADR Monitoring System during 2009-2018 was systematically analyzed, and its general characteristics were analyzed using descriptive statistical methods. The results showed that among the 407 cases of spontaneous reporting system(SRS) data, 401 cases were general ADR/AE, accounting for 98.5%, and 6 cases were severe ADR/AE, accounting for 1.5%; there were more females than males(171/150) in ADR/AE, and they were mainly middle-aged and elderly people aged 45-64 years(152 cases, accounting for 37.35%); gastrointestinal system(23.89%) was mostly involved in ADR/AE. The top ten clinical symptoms were nausea(15.49%), dizziness(9.88%), vomiting(8.11%), rash(5.60%), chest tightness(5.46%), palpitations(5.31%), pruritus(4.72%), headache(4.57%), abdominal distension(3.83%), gastric dysfunction(3.54%); proportional reporting ratio(PRR) and Bayesian confidence progressive neural network method(BCPNN) were adopted to mine ADR/AE warning signals. Due to the small sample size, there were only 0-2 ADR/AE cases with various symptoms in many quarters, with no warning signal by PRR and BCPNN methods. The findings suggest that ADR/AE of Ginkgo biloba Dropping Pills based on SRS system was not recorded in the package insert, and further active monitoring studies shall be conducted to improve relevant ADR/AE information and pay attention to its clinical drug safety issues.

To explore the general characteristics of adverse drug reactions/adverse events(ADR/AE) in patients after using Shujin Jianyao Pills, and explore risk warning signals, this study analyzed 166 cases of ADR/AE reports of Shujin Jianyao Pills collected from 2005 to 2017 based on the National Center for ADR Monitoring spontaneous reporting system(SRS). And the descriptive statistical method was used to analyze general characteristics. The results showed that among the 166 ADR/AE cases, 106 cases were female patients, accounting for 63.86%. Middle-aged and elderly people aged 45 to 64 accounted for the largest proportion(82 cases, 49.40%), which were followed by elderly aged 65 and over(48 cases, 28.91%). ADR/AE involved a wide range of systems and organs, of which skin and its accessories were the most damaged(30 cases, 12.93%), which were followed by systemic damage(27 cases, 11.64%). The top 10 ADR/AE manifestations were rash(15 cases, 6.33%), nausea(14 cases, 5.91%), dizziness(14 cases, 5.91%), abdominal pain(12 cases, 5.06%), pruritus(11 cases, 4.64%), low back pain(11 cases, 4.64%), vomiting(10 cases, 4.22%), hepatocyte damage(9 cases, 3.80%), headache(9 cases, 3.80%), and diarrhea(7 cases, 2.95%). Bayesian confidence propagation neural network(BCPNN) was used to mine the ADR/AE risk early warning signal of Shujin Jianyao Pills, and the propensity score method was used to control the balance of confounding factors. The results suggested warning signs for nausea, diarrhea, rash, and dizziness, vomiting, abdominal pain, headache, liver cell damage. This study provides a basis for the post-marke-ting safety evaluation of Shujin Jianyao Pills, and can provide guidance for its rational clinical use and risk management.
