Evaluation of some photosensitizers against the cotton leaf worm, Spodoptera littoralis (Lepidoptera: Noctuidae), in relation to spectral and thermal reflectance.

Photosensitizing compounds are eco-friendly promising organic dyes for managing insect pests without facing the risk of resistance. The photodynamic efficacy of four Photosensitizing compounds (rose Bengal, rhodamine B, methylene blue and methyl violet) was monitored against the third larval instar of Spodoptera littoralis (Boisduval), after exposure to sunlight. The LC values of the four compounds; rose Bengal, rhodamine B, methylene blue and methyl violet recorded 0.

Laparoscopic gastrectomy with D2 lymphadenectomy for gastric cancer: initial Egyptian experience at the National Cancer Institute.

Background: Laparoscopic gastrectomy has been used as a superior alternative to open gastrectomy for the treatment of early gastric cancer. However, the application of laparoscopic D2 lymphadenectomy remains controversial. This study aimed to evaluate the feasibility and outcomes of laparoscopic gastrectomy with D2 lymphadenectomy for gastric cancer.

TRAM flap for immediate post mastectomy reconstruction: comparison between pedicled and free transfer.

Unlabelled: Breast reconstruction after mastectomy is primarily carried out to improve the patients' quality of life. The most commonly used autologous tissue for reconstruction is the transverse rectus abdominis musculocutaneous flap (TRAM). The TRAM flap could be transferred either as pedicled or a free flap with microvascular anastomosis.

Near total laryngectomy: a versatile approach for voice restoration in advanced T3 and T4 laryngeal cancer: functional results and survival.

Purpose: Creation of a tunneled mucosal shunt between the trachea and pharynx that is controlled by remaining intrinsic laryngeal musculature with its nerve supply is an acceptable voice restoration procedure for advanced T3 and T4 laryngeal cancer. Such a tunnel will allow unilateral direction of air from lung to pharynx during phonation and will prevent aspiration since deglutition is a vagal mediated response which will induce contraction of tubed laryngeal musculature preventing aspiration. We previously reported our preliminary experience with the technique and we adopted the voice restoration approach based on the concept of the near total laryngectomy thereafter.

Surgery as a single modality therapy for squamous cell carcinoma of the oral tongue.

Purpose: The treatment of squamous cell cancer of the oral tongue remains a challenging clinical problem. The efficacy of primary treatment with surgery versus radiation therapy for early stage disease and an adequate treatment paradigm for the clinically negative neck continues to be the subject of clinical debate. We have reviewed our experience in the treatment of oral tongue cancer with surgery as a single definitive treatment modality.

Squamous cell carcinoma of the floor of mouth: a 20-year review.

Background: This study retrospectively examines our treatment choices and outcomes with patients diagnosed with squamous cell cancer of the floor of mouth. Because of our division's past strong surgical bias in the treatment of this disease, we have assessed the results of a patient population treated largely by surgical extirpation. This clinical information has been used to draw conclusions and formulate treatment paradigms for patients with floor of mouth cancer.

Clinical significance of colorectal cancer: metastases in lymph nodes < 5 mm in size.

Background: The clinical significance of metastases in small lymph nodes is not known. Our objective was to evaluate possible relationships between the number and size of lymph node metastases and survival after potentially curative colorectal resection.

Methods: A retrospective chart review was performed in patients with Dukes'C (any T, N(1-3') M0) colorectal cancers from July 31, 1971 to December 31, 1987.
