Objective:
To summarise our experience with maggot debridement therapy (MDT) in relation to pain observed in patients treated in 16 departments and units of the Hadassah Hospital in Jerusalem, Israel.
Method:
A secondary analysis of data from 435 patients. Maggots were either placed directly on the wound using a cage-like dressing (DA), or they were applied to the wound encased in a previously prepared hermetic tea-bag like pouch (TBA). During each treatment, patients were asked whether they felt any difference in the level of pain before and during MDT treatment.
Results:
Overall, 165 patients (38%) reported increased pain during MDT. Seventeen patients (41%), who were treated with the TBA technique, and 148 patients (38%), who were treated with the DA technique, reported increased pain and were treated with analgesics before or during MDT. In five patients, the treatment had to be discontinued due to uncontrolled pain during MDT. Pain control measures were undertaken in patients who were already in intense pain prior to the initiation of MDT and in those patients who reported intense pain during DA treatment. The measures included shorter periods of application of maggots, use of the TBA rather than DA technique, and applying relatively small maggots as well as a smaller number of maggots during an MDT session. In patients who continued reporting intense pain, systemic analgesic medications and peripheral nerve blocks were used.
Conclusion:
Since a full debridement requires an average of 2-3 maggot cycles, which last 3-5 days, and since a large percentage of patients treated with MDT complain of pain that may last throughout the therapy period, it is deemed worthwhile and even essential to titrate analgesics as needed and be prepared to treat patients even with potent analgesics, such as opioids. In cases when pain is intense and uncontrolled with systemic medications, peripheral nerve blocks should be considered.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
