Profile of breast lesions among women with positive biopsy findings in Yemen.

This study described the profile of breast pathology based on records from a reference histopathology laboratory in Yemen of 773 women with positive biopsy or mastectomy findings. Cancers were classified according to the International classification of diseases for oncology. Benign lesions were found in 79.9% of cases. Fibroadenoma was the most prevalent lesion (30.0%) with a mean age at presentation of 22.2 years, followed by fibrocystic disease (27.4%) and breast inflammation (13.1%). Invasive carcinoma was found in 155 cases (20.1%), at a mean age of 44.7 years.

The pattern and distribution of malignant neoplasms among Yemeni patients.

OBJECTIVE: This research was aimed at describing the pattern of malignancies among 1,491 patients during 1996 through to 2000 and to explore association with age, sex and site of cancers. METHODS: A research was carried out at a Histopathology Center in Sana'a, Republic of Yemen between the period August 1996 through to August 2000. All specimens were diagnosed by one pathologist based on the International Classification of Disease for Oncology. RESULTS: Results revealed comparable male: female ratio (1:0.92) and mean age of 46.1 +/- 22.8 in males and 44.2 +/-18.3. The most common cancers were the gastrointestinal tract malignancies, 22%. Lymph node cancers constituted 16%, followed by head and neck malignant tumors 12%, skin 10%, urinary tract 8%, bone and soft tissue 8%, breast 8%, female genital system 5%, thyroid gland 2% and finally male genital system, bone marrow and central nervous system/eye 2% each. For female patients breast cancers and gastrointestinal tract cancers were equally the most frequent malignancies. Skin cancers, followed by gastrointestinal tract and male genital system affected mostly older age patients. While bone marrow followed by central nervous system and eye, then bone and soft tissue cancers were mostly diagnosed in young age patients. Within the gastrointestinal tract liver was the most affected site 33% and adenocarcinomas were the most frequent diagnosed type 42%. Among lymph nodes malignancies non-Hodgkin's lymphoma constituted 42%. Oral cavity cancers constituted 73% of head and neck malignancies, where squamous cell carcinoma constituted 65%. CONCLUSION: Gastrointestinal tract in general with breast in females, were the most frequent sites of malignancies in the Republic of Yemen. Adenocarcinoma and squamous cell carcinoma were the most frequent types.

Rate of wound infection after clean surgery.

OBJECTIVE: The aim of this study is to determine the rate of wound infection after clean surgical operations without using of prophylactic antibiotics and to investigate the relation between surgical wound infection with patient s age, sex, type of hospital, and the difference in surgeons. METHODS: This study carried out in Sana'a city on 238 patients who underwent clean operations in two governmental and two private hospitals by four surgeons between 1998-1999. Patients at high risk of infection were excluded. RESULTS: The rate of wound infection was 8%. The study revealed statistically significant difference (P=0.011) in the infection with elderly patients (25% infection in elderly patients compared with 6% in less than 60 years old patients). It was also found that wound infection rate differs with the difference in surgeons; the rate did not exceed 3% with one surgeon (the author) in comparison with 13% with other surgeons. This difference is statically significant (P= 0.003). Differences in rates of infection with sex of the patient and type of the hospital were statistically insignificant. CONCLUSION: The study was concluded that the rate of wound infection after clean surgery without prophylactic antibiotics in Yemen is higher than many other countries, surgeon and the age of the patient were the risk factors of importance. It is suggested to give antibiotics as prophylaxis to elderly patients and to rise the awareness of the surgeons and nurses in order to improve their practice.
