The maternal deaths occurring in the Kilimanjaro Christian Medical Center (KCMC), which serves as a supraregional reference hospital for the 5 regions of Northern and Central Tanzania, are reviewed for the 1971-1977 period and avoidable factors are discussed. All deaths occurring within the hospital during pregnancy or the first 6 weeks of the puerperium were included in this survey. Postmortem examination was performed in 35% of the cases. In the remaining cases the diagnosis was made on clinical grounds. During the period under review, there were 10 deaths among 83 cases, a mortality of 12%. The major cause of rupture was obstructed labor associated with a contracted pelvis or abnormal lie. 25% of the patients had had a previous cesarean section scar give way. 2 other deaths were attributed to anesthetic accidents and 1 was probably due to pulmonary embolism. The primary cause of death in the 7 remaining cases was hemorrhage (4) and sepsis (3). If deaths from ruptured uterus are to be avoided, early diagnosis is essential. 1044 cases of moderate and severe EPH gestosis (preeclampsia) were treated in KCMC during the period under review together with 54 cases of eclampsia. There were 5 deaths among the patients with eclampsia, a mortality of 9%. In addition to the 11 sepsis deaths there were 3 others included among the cases of ruptured uterus. There were 4 cases of septic abortion and 3 of those admitted to criminal interference. Preexisting anemia was a complicating factor in 5 cases, all of whom died within 15 minutes of arrival. There were 4 deaths among 251 cases of ruptured ectopic pregnancy. There were 10 deaths associated with cesarean section among 1271 sections peformed during the period under review. Deaths from associated diseases included the following: enterocolitis (12 deaths); renal and hypertensive disease (4 deaths); cardiac disease (2 deaths); anemia (2 deaths); malaria (2 deaths); tuberculous meningitis (2 deaths); and miscellaneous associated conditions (11 deaths).

This study attempts to collect reliable data on maternal deaths, estimate maternal mortality rate for the western state of Nigeria, and identify major causes of maternal deaths in the state. Standardized questionnaires were sent to randomly selected medical institutions (5 specialist hospitals and 25 general/district hospitals) in the state; only 23 institutions (4 specialist and 19 district/general hospitals) completed the questionnaires. The results show that maternal mortality ranged from 0/1000-13.3/1000 total births in 1972 and 0/1000-11.0/1000 total births in 1973; overall maternal mortality rate was 3.8/1000 in 1972 and 4.7/1000 in 1973. Mortality was higher among unbooked patients, accounting for 71.2% and 66.4% of total deaths in 1972 and 1973. Hemorrhage (antepartum and postpartum), obstructed labor (uterus unruptured and ruptured), eclampsia and anemia of pregnancy accounted for over 80% of total deaths. Nonobstetric causes of maternal deaths including poisoning, infective hepatitis, meningitis, encephalitis, bronchial asthma, hypertension, and pulmonary embolism. The major causes of death in this series were preventable. Maternal mortality is associated with age, parity, and past reproductive and medical history. The high maternal death rate in this study is compounded by nonutilization of available medical services by pregnant women most especially for antenatal care, the lack of basic essential life-saving facilities (e.g., for blood transfusion), lack of adequate transportation system, failure of medical/nursing personnel to refer patients early to specialist hospitals, and relative lack of obstetric services both in quality and quantity all over the country. Better coordination and integration of health services are needed, as are nationwide data collection of maternal death statistics, publication of periodical reports, and establishment of standards for overall maternity care.

Maternal mortality is examined from June 1980 to December 1986 at Mulago, Nsambyo, Old Kampala, Rubaga, and Mengo Hospitals in Kampala, Uganda. Clinical or immediate causes, direct and indirect, were recorded from case summary forms based on ICD9 definitions of obstetric complications. The nonabortion maternal mortality rate (NAMMR) was 2.65/1000 deliveries (580 deaths); the abortion-related maternal mortality rate (ARMMR) was 3.58/1000 abortions. The hospital maternal mortality rate was 2.0/1000 deliveries. 75% of maternal deaths of women of 28 weeks' gestation or more had delivered outside the hospital. NAMMR doubled between 1980-86, a statistically significant increase. ARMMR increases were almost significant. 75% were direct obstetric and 21% were indirect obstetric causes. 38% had clinical anemia, 29% had some sepsis, 18% had substantial bleeding, and 14% had obstructed labor. Other contributing conditions were pneumonia, ruptured uterus, laparotomy, evacuations and curettage, malaria, preeclampsia, sickle cell anemia, pulmonary embolism, malnutrition, tetanus, meningitis, prolonged labor, and hepatitis. At admission, 48% were in poor condition, 30% in good condition, and 22% in fair condition. 27% had sickle cell anemia, high blood pressure, multiple pregnancy, or malaria at admission. 64% were admitted within 24 hours after delivery, 67% 1-7 days after delivery, and 92% 7-42 days after delivery. Those in good condition were all admitted 7 days postdelivery. 41% of deaths were due to lack of drugs, 7% lack of fluids, 20% with theater problems, 14% with doctor-related factors, and 3% with midwife-related factors. Better information is needed on mortality before delivery, mortality in hospitals vs. outside, and mortality from abortion, and ectopic and hydatidiform molar pregnancies. An explanation given for the increase in maternal mortality is the decline in economic conditions. Abortion complications may be due to the concealment practiced. Causes are consistent with trends from the 1950s, 1960s, and 1970s in Uganda and developing countries in general. Availability and accessibility of gynecological and obstetric services needs great improvement. Training traditional birth attendants and obtaining rural ambulance services are also needed. Health workers lack creativity and imagination for developing country conditions; scarce resources are not the only problem.

Common intracranial complications following head injury are meningitis, usually associated with a basilar skull fracture or open-depressed skull fracture; delayed hematoma; hydrocephalus; and vascular injuries. Prophylactic antibiotics are not recommended for the management of basilar skull fractures. The best means of preventing infection from open-depressed skull fractures is operative debridement and thorough irrigation, though recent evidence suggests that select cases can be safely managed without operation. Serial CT scans should be obtained in severely head-injured patients to identify delayed hematomas. CT and MRI scans obtained several weeks or months after severe head injury frequently reveal enlarged ventricles, though only a small percentage of these patients have clinical hydrocephalus. Those that do, often benefit from a shunt. Vascular injuries frequently are not detected until ischemic symptoms develop hours or days after the injury. Recommended treatment for intimal tears or dissection is full anticoagulation, but in those with cerebral contusions or other intracranial lesions, this may present an unacceptable risk for intracranial hemorrhage. Pulmonary infections frequently occur following head injury, and can be associated with admission to the ICU and intubation. A large percentage of these infections are caused by enteric gram-negative organisms, and aggressive treatment with appropriate antibiotics is necessary. Aspiration of gastric contents is common in head-injured patients and is frequently complicated by bacterial superinfection. The routine use of antacids and H2 blocking agents leads to bacterial colonization of the stomach with anaerobes and gram-negative aerobes. Thus, empiric therapy for aspiration pneumonia should include clindamycin. Sinusitis is a frequent cause of fever and leukocytosis in patients with nasotracheal or nasogastric tubes in place for several days and often subsides spontaneously with removal of the tubes. Pulmonary edema is often caused by excessive fluid administration during resuscitation of these patients, and can be avoided by monitoring central venous pressures. Pulmonary edema may also be caused by ARDS, excessive catecholamine release, or primary cardiac failure. Most of these patients will benefit from early intubation and PEEP. Pulmonary emboli most often originate from deep venous thrombi, and there is increasing evidence that prophylaxis with low-dose heparin and pulsating boots can significantly reduce the incidence of both complications. Erosive gastritis is found in the majority of severely head-injured patients and may be due to ischemia of the gastric mucosa as well as gastric hyperacidity.(ABSTRACT TRUNCATED AT 400 WORDS)

An open retrospect study, including five patients, has been entered on, in order to estimate the efficacity and the tolerance in a more than sixty years old person, of the association ampicillin-cotrimoxazole for the treatment of the meningitis due to Listeria monocytogenes. In the infectious sphere, all the patients recovered; one death, by pulmonary embolism at the 21sh day of evolution, is to be deplored; two erythematous rashes have been observed. These preliminary results are encouraging and incite to carry on the evaluation of this protocol, which could replace the classical therapy; ampicillin-aminoglycosides, where only the ampicillin reaches effective concentrations on the level in the cerebro-spinal fluid.

From 1966 through 1985, a total of 640 patients received 739 renal transplants at a single center transplantation program. Of 245 total deaths, a slide and chart review of all 116 autopsied cases (47%) identified the major causes of death as pneumonia (n = 43), sepsis (n = 32), hemorrhage (n = 15), peritonitis (n = 11), meningitis (n = 7), and pulmonary embolism (n = 5). Eighty-five (73.3%) of these patients died of complications directly associated with immunosuppression, almost all (n = 82) as a result of infection. Organisms most frequently identified at death were gram-negative bacilli (n = 72), Candida species (n = 23), cytomegalovirus (n = 17), enterococcus (n = 14), Staphylococcus aureus (n = 11), Aspergillus species (n = 10), Pneumocystis carinii (n = 5), and mycobacteria (n = 5). Significant associations were found between bolus steroid antirejection therapy and infection with Aspergillus cytomegalovirus. Diabetics had a higher incidence of fungal infections and bowel perforation than nondiabetics. During this 20-year period, overall one-year actual patient survival rates for the four respective five-year intervals increased dramatically (69.9%, 68.2%, 83.3%, and 91.8%), but the normalized death rate showed a smaller decrease for infectious vs noninfectious causes.

Maternal mortality was examined in a semi-urban Nigerian community over a 10-year period. Maternal mortality was defined as death occurring as the direct result of childbearing and measured per 1000 births. Abortions at below 20 weeks gestation were excluded. From 1966 to 1975, there were 90 maternal deaths out of 13,182, a rate of 6.8/1000. The hospital records of the Baptist Medical Center, located in the western part of Nigeria, were carefully reviewed and cross-checked with obstetric statistical records. Only 13 of the deaths occurred in hospitalized patients. 78 (80%) were due to direct obstetric causes; 12% were from nonobstetric causes. Anemia due to blood loss was the leading casue of death, accounting for 30, or 33%, of the deaths. Anemia, with or without congestive heart failure accounted for 7 deaths. Infection was responsible for 5 deaths. Ruptured uterus, preeclampsia, and eclampsia occurred in equal percentages, 10-11%. Indirect obstetric deaths, such as sudden death, accounted for 10 deaths. 50% of these were anesthetic deaths; the remainder were due to pulmonary embolism. Sickle cell intrapartum crisis was the cause of 1 death. Associated causes included featured pneumonia, nephritis, hepatitis, meningitis, enteritis, and cerebrovascular accident. Parity ranged from 0-11. 25 babies were salvaged in this series. Prevention continues to be the cornerstone in improving maternal mortality figures in developing countries. The Baptist Medical Center's model for providing maternal care is described briefly and is identified as responsible for the encouraging decline in the maternal mortality rate.

We report on 130 ethmoidal cancers. 96 (74%) were adenocarcinomas (ADKE). 110 were operated upon between 1984 and 1996: 9.1% T1 + T2, 27.7% T3, 36.2% T4a, 27% T4b. Neoadjuvant chemotherapy was administered in 93 patients (76 ADKE). Combined surgical route was performed 103 times, sub-fronto-orbito-nasal (SFON) route 7 times. Post-operative radiotherapy was performed in 36 patients. Complete clinical and radiological response to chemotherapy was noted in 21.5% of cases (23% of ADKE). Post-operative mortality concerned one patient who died from a pulmonary embolism during the third post-operative week. Morbidity included: 3 transient clinical rhinorrheas, 5 meningitis (one of which was responsible for heavy psycho-intellectual disability), 4 deep suppurations associated with osteitis of the bone flap and two superficial suppurations. 44 patients had a local recurrence (10 ADKE). No recurrence appeared in complete chemoresponders. Systematic preservation of intra-orbital contents did not increase the risk of local failure. Eleven patients (4 ADKE) developed cervical nodes and/or systemic metastasis. Death occurred after a mean of three months following the diagnosis of metastasis. Survival rate was: 60% at 3 years, 51.5% at 5 years, 32.5% at 10 years. ADKE survival rate was: 55% at 3 years, 51.5% at 5 years, 23% at 10 years. Survival ws related to tumoral extension: 75% at 5 and 10 years for T3, 45% at 5 years and 38% at 10 years for T4a, 40% at 3 years and null at 5 years for T4b, 5 and 10 years survival rate of complete chemoresponders are 100% whatever the tumour. Prognosis remained poor for epidermoid carcinomas (survival rate: 36% at 3 years, 0% at 5 years) and for melanomas (mean survival: 19.6 months). Post-operative radiotherapy should be indicated for large tumors T3, T4a and T4b).

We report here, we believe for the first time, the primary antiphospholipid syndrome, presenting with fever, meningismus and skin rash. Serology was positive for antiphospholipid antibodies but negative for antinuclear factor. Such presentations, once meningitis has been excluded, should be screened for antiphospholipid antibodies. If serology proves to be positive, anticoagulation for life should be considered to avoid thrombotic episodes and death due to pulmonary embolism.

Forty-three patients with fractures of the thoracolumbar spine submitted to surgical treatment using the Harms method (dorsoventral operations) were studied prospectively with a follow-up of at least 12 months and evaluated on the basis of clinical and radiologic parameters and in relation to their professional activities. Thirty-five patients (81.3%) were males and eight (18.7%) females, ranging in age from 17 to 67 years (mean 34.08+/-11.51 years). Seven patients (16.2%) presented fractures of more than one vertebra, and associated lesions were present in 15 patients (34.8%). Monosegmental fixation was performed in 7 patients (16.3%), bisegmental fixation in 29 (67.4%), and trisegmental fixation in 7 (16.3%). No patient was submitted to any type of external immobilization during the postoperative period and all patients were allowed to sit up in bed and to walk as soon as their clinical conditions permitted. Thirty-nine patients were followed up for a period ranging from 12 to 36 months (mean 16.58+/-6.83 months). Four patients died during the postoperative period (three of pulmonary embolism and one of septicemia). Forty-two patients sat up in bed between the 2nd and 6th postoperative day, and those who did not present a disabling lesion (Frankel D or E) or other associated lesions walked between the 4th and 10th postoperative day (mean 6.14+/-6.06 days). The neurological signs and symptoms improved in 16 patients (37.3%), were unchanged in 26 (60.4%), and worsened in 1 (2.3%). Twenty-three patients (87.5%) who had no neurological damage (Frankel E) returned to their professional activities after respective periods of disability of 1 month (three patients), 2 months (four patients), 3 months (one patient), 4 months (seven patients), 5-7 months (five patients), 8-12 months (one patient), and more than 12 months (three patients). The ability to work of the 24 patients without neurological damage was 100% in 21, 50% in 2, and zero in 1. The ability to walk of this group of patients was 1-5 km for 4 and more than 5 km for the remaining 20 patients. The complications observed were death (four patients; three cases of pulmonary embolism and one case of septicemia), infection (two patients), Stevens-Johnson syndrome (one patient), and meningitis (one patient). The mean kyphosis of the fractured segment was 22.17 degrees +/- 10.97 degrees preoperatively, 8.55 degrees +/- 6.9 degrees postoperatively, and 10.30 degrees +/- 8.84 degrees on the occasion of late evaluation. No loss of correction occurred in 28 patients (71.8%), a 5 degrees loss was observed in 3 patients (7.6%), a 6 degrees loss in 3 (7.6%), a 7 degrees loss in 3 (7.6%), and a loss of more than 10 degrees in 2 (5.2%).
