This paper reports the experimental investigation of the agronomic performance of okra under various quantities of both sawdust and trash mulches. The location of the field was the research farmland of the Federal Polytechnic Ado Ekiti Nigeria; Lat 6?N and Long 16?E. The experimental design used was complete randomized design with 6 treatments on both specimens. The experiments were repeated the following year on the same plot but with transposed plot allocation. Soil moisture loss from uncovered plot was with the highest value dropping to less than 2 per cent. It was followed by that of trash plot and the lowest loss was on sawdust mulched plot. The number of leave formed by okra on sawdust, trash and no mulch plots was 43, 36 and 27 respectively while maximum girth diameter was 37 mm in both trash and sawdust covered plots but okra plant on control plot attained only 26 mm diameter. Fruit yield were almost similar to trash and sawdust mulched okra having 7.5 and 7.6 Tonnes/Ha respectively while control plot recorded 5.2 Tonnes/Ha. The ash content of dry matter of sawdust, trash and no mulched plants was 0.25, 0.20 and 0.17 kg respectively. It was concluded that sawdust could perform as much as the traditional trash materials commonly used in Southwestern Nigeria. Also, sawdust was a good material for conserving soil moisture.
Retropharyngeal emphysema is a potentially life threatening condition which may
require urgent diagnosis and intervention. It has been documented to occur
following trauma to the aerodigestive tract and is usually accompanied by
subcutaneous emphysema of the cervical region. This condition may be complicated
by mediastinal emphysema and pneumomediastinum. Foreign body ingestion is
quite common in little children and in this environment; a cultural practice
is for mothers or other caregivers to attempt to remove these foreign bodies
by forcing their finger(s) down the oropharynx and Hypopharynx of these young
children. This usually results in injuries to these anatomical sites.
Retropharyngeal emphysema complicating this practice is rarely reported. Case
presentation: We present the case of a 4-year-old Nigerian boy who presented
with stridor and severe dyspnoea following repeated attempts at removal of a
purportedly ingested foreign body by his mother. Examination revealed oedema of
the soft palate with small multiple bleeding shallow lacerations of the oropharyngeal
walls. Oxygen therapy was commenced and preparations for urgent upper airway
intervention made. Soft tissue neck X-ray revealed retropharyngeal and
subcutaneous emphysema with upper airway compromise. Conservative treatment
with high dose steroids and antibiotics led to a gradual resolution of the
condition. Conclusion: This is a rarely reported complication of this relatively
common socio-cultural “foreign body removal method”. Public awareness is
required to stop this potentially life threatening practice.
