Isolation, characterization, and genome analysis of novel bacteriophage - Stenotrophomonas phageCM1

A common environmental bacteria called Stenotrophomonas maltophilia has become an organism responsible for significant nosocomial infection, mortality in immunocompromised patients, and significantly increasing morbidity and is challenging to treat due to the antibiotic resistance activity of the organism. and bacteriophage therapy is one of the promising treatments against the organism. In this research, we isolated, identified, and characterized Stenotrophomonas phage CM1 against S. maltophilia. Stenotrophomonas phage CM1 head was measured to have a diameter of around 224.25 nm and a tail length of about 159 nm. The phage was found to have noticeable elongated tail spikes around 125 nm in length, the Myoviridae family of viruses, which is categorized under the order Caudovirales. The ideal pH for growth was around 7, demonstrated good thermal stability when incubated at 37-60 °C for 30 min or 60 min, and phage infectivity decreased marginally after 30 min of incubation at 1-5% chloroform concentration. Phage was 3,19,518 base pairs long and had an averaged G + C composition of 43.9 %; 559 open-reading frames (ORFs) were found in the bacteriophage genome, in which 508 of them are hypothetical proteins, 22 of them are other known proteins, 29 of them are tRNAs, and one of them is restriction enzyme. A phylogenetic tree was reconstructed, demonstrating that CM1 shares a close evolutionary relationship with other Stenotrophomonas phages.

Primary laryngopharyngeal reconstruction using pectoralis major myocutaneous flaps - Our experience

Twenty-one eases of laryngectomy/laryngopharyngectomy that required primary reconstruction with P. M. M. C flaps at the Division of Surgical Oncology, Regional Cancer Centre, Triyandrum were studied retrospectively from July 1995 to December 2090 and compared with the in cases where primary closure of the neopharynx was done.Four of the 21 cases developed post operative pharyngocutaneous fistulae PCF(I9%) which healed Complefely within an average period of I week compared to 4 PCFs (40%) after primary closure. (n=10), where the average healing time was 12.5 days, with I recurrence. The average duration of Onset of fistula was relatively earlier in cases that required primary closure (II days) compared to those cases where P. M. M. C flap was used for reconstruction (12.5 days). All complications were Wound related and managed conservatively.

Intramuscular lipomatosis of tongue

A rare case of intramuscular lipomatosis of the tongue with intramuscular invasion in a 42 year old man is presented. The literature is reviewed and the clinical features, pathology, and treatment are discussed briefly.

Nasolabial flaps in oral reconstruction: an analysis of 224 cases

The nasolabial flap is a simple option for the reconstruction of selected oral defects. Though its use in floor-of-mouth reconstruction has been described, other uses in the oral cavity have not been studied extensively. We present a series of 224 oral malignancies where the nasolabial flap was used for reconstruction after surgical excision.
