Appendicitis During Pregnancy

Acute appendicitis is the most common extra-uterine surgical emergency requiring immediate surgical intervention during pregnancy [1]. Six young female patients presented with appendicitis during May 1996 to May 2001 in different service hospitals. Five patients underwent emergency appendectomy successfully. Gestational age at presentation included first trimester in 4 patients, second trimester in 2 patients and none in third trimester. 84% had pathologically proven acute appendicitis. One patient presented with appendicular lump in first trimester, proved on ultra sonography examination, which was treated by Oshner Sherren regime and subsequently interval appendectomy was done in second trimester. No long term adverse maternal morbidity or mortality was reported. One patient had premature onset of labour and delivered. Natural history of acute appendicitis is not changed during pregnancy while gestational physiological changes obscure the accurate diagnosis of acute appendicitis.Key Words: Acute appendicitis, Appendectomy, Pregnancy     

Obstetric and nonmalignant gynecologic bleeding: treatment with angiographic embolization

Eight patients (seven post partum, one post abortion) with massive pelvic hemorrhage related to pregnancy and one patient with uncontrollable bleeding following a cervical biopsy underwent angiography to facilitate the identification and treatment of bleeding sites. In all nine patients pelvic hemorrhage was successfully controlled with embolization under angiographic guidance. Angiographic embolization allowed preservation of the uterus in six patients referred prior to hysterectomy, and one patient subsequently became pregnant. When conservative measures and minor surgical repairs have failed, embolization should be the next step in the treatment of postpartum hemorrhage to avoid major surgery in an unstable patient and to maintain reproductive function.

失眠的评价

失眠的定义失眠分为急性和慢性失眠.急性失眠通常持续时间不超过2 w,与应激状态有关,例如上班、搬家、婚姻或亲人朋友的去世等.而慢性失眠则是失眠持续超过3 w以上,或者不充足睡眠伴随着日间睡意和抑郁,且持续时间不少于1个月.     

Asian paralysis syndrome

We report 20 children admitted to the paediatric ward of a public general hospital for acute flaccid paralysis, which was bilaterally symmetrical in all cases and was associated with bulbar involvement in eight of them. Recovery was partial. Nerve conduction studies showed motor axonal neuropathy. This new disease, variously termed as non-inflammatory neuropathy/Chinese paralysis syndrome must be differentiated from Guillain-Barré syndrome (GBS) and poliomyelitis. Both GBS and Asian paralysis syndrome have bilaterally symmetrical flaccid paralysis but GBS tends to have sensory involvement, full recovery occurs in 90% of cases and nerve conduction shows demyelinating neuropathy. Asian paralysis syndrome and poliomyelitis are pure motor lesions without sensory changes and partial recovery, but poliomyelitis differs in that paralysis is asymmetrical and unequal, muscle spasm is always present in the initial stage and there are prodromal symptoms. Nerve conduction studies show anterior horn cell disease. This new entity, common in Asian populations, assumes public health importance when it mimics poliomyelitis in a country that has tried to eliminate poliomyelitis by universal immunization. To the best of our knowledge, this is the first report of Asian paralysis syndrome in children in our area.     

Warfare vascular injuries

Vascular injuries as a part of combat injuries have been recorded since times immemorial. Responsible for death due to exsanguination, the management of vascular injuries was ligation or amputation till the landmark Vietnam experience. The present day management has evolved with advances in modern technology and may start at the battlefield with the application of a tourniquet with the definitive treatment continuing beyond the combat operation theatres. A basic understanding of both blunt and penetrating vascular injuries will help minimize mortality and morbidity.
