Piperacillin/tazobactam is a bacteriolytic combined antibiotic. The least common reported adverse reactions of piperacillin/tazobactam are haematological reactions (<1%). The use of piperacillin/tazobactam during pregnancy is considered to be moderately safe (pregnancy category B) for the human embryo-foetus. This is a case of a pregnant patient (22 weeks of gestation) who was admitted to the Women's Hospital, Doha, Qatar and was treated for preterm premature rupture of membrane with erythromycin for 10 days. Afterwards, she was treated with piperacillin/tazobactam for asymptomatic urinary tract infection (pseudomonas species). After 15 days, she developed fever, leucopenia, neutropenia and thrombocytopenia. These adverse reactions were reversed after the discontinuation of piperacillin/tazobactam combination. In Qatar and worldwide, there are few reported cases regarding bone marrow suppression or fever induced by piperacillin/tazobactam in general and during pregnancy. Using the Naranjo Adverse Drug Reaction Probability scales, the score was found to be 8, representing a probable adverse drug reaction.

An example of a simple event is a coin toss. The result of a coin toss is either a head or a tail. Here, head and tail are two simple events. These two simple events make up the sample space. Further, the probability of an event occurring falls within the range of 0 to 1. The probability of an...

The outcomes of a binomial experiment fit a binomial probability distribution. A statistical experiment can be classified as a binomial experiment if the following conditions are met:
There are a fixed number of trials. Think of trials as repetitions of an experiment. The letter n denotes the number of trials.
There are only two possible outcomes,...
