Management of complex orbital fractures.

The treatment of orbital injuries has evolved considerably over the last two decades. We describe strategies involved in the emergency management of orbital injuries, the use of imaging, preformed and customised materials for reconstruction, and endoscopic techniques.

Gestational trophoblastic neoplasia: are we compliant with the standards?

This study was conducted to assess the management of gestational trophoblastic diseases (GTN) in a district general hospital in accordance with the RCOG guidelines. A retrospective case notes review over a 5-year period found a total of 23 patients treated in this hospital. The annual incidence of hydatidiform mole was 1.3/1,000 deliveries (3,500 deliveries per annum). Ultrasound scanning diagnosed or suspected GTN in only nine of the 23 cases (39%); six women (26%) were diagnosed as missed miscarriage and another six (26%) were diagnosed as incomplete miscarriage. Eleven patients (48%) were not suspected before histological diagnosis. A total of 16 of the 23 cases (70%) were complete moles and the rest were partial moles; 19 of the 23 (83%) were referred to a specialist centre of which 60% were referred within 1 month. The rest were not documented. Contraceptive advice was documented only in 11 case notes (48%). Women with molar pregnancy should be referred to a specialist centre as early as possible and within 2-4 weeks of histological diagnosis, after appropriate counselling and contraceptive advice.

Obstetric outcome in women complaining of reduced fetal movements.

Reduction of fetal movements causes concern and anxiety and is a common indication for the assessment of fetal well-being. The aim of this study was to review the outcome of women who presented primarily with reduced fetal movements and to compare with women of similar age and gestation who did not present with reduced fetal movements (controls). Some 19% of intrauterine growth restricted babies were found in the study group, compared with none in the control group. In the study group, 32% of women needed intervention solely due to fetal compromise compared with 21% in the control group. There was no perinatal or neonatal death in either group. We suggest that these women should be carefully investigated and monitored to improve the obstetric outcome.

Ultrasound-guided core biopsy for the diagnosis of lumps in the neck: results in 82 patients.

Ultrasound-guided core biopsy of nodes (n = 78) and other lumps (n = 4) in the neck allowed a firm histological diagnosis in 76 of 82 patients (93%). Of the remaining six patients, histological examination was equivocal in four and valueless in two. Of 18 patients with a diagnosis of lymphoma only 3 required excision of the node to provide additional information for the planning of treatment.

What investigation is appropriate following maternal perception of reduced fetal movements?

It has been proposed that maternal perception of reduced fetal movements may be indicative of placental insufficiency, and that women who present with reduced fetal movements should be investigated for evidence of placental insufficiency. A retrospective case notes-based analysis of patients presenting with reduced fetal movements was undertaken. There were 92 live-born infants, the mean gestation at delivery was 39(+4) weeks. The median birth weight was 3,140 g. A total of 29.1% of infants had a birth weight of less than the 10th centile. A total of 35 women underwent ultrasound assessment of fetal growth and liquor volume. Measurement of symphyseal fundal height (SFH) had a greater specificity than a single ultrasound assessment in the prediction of IUGR at delivery. To reduce unnecessary intervention, SFH measurement may be used as a screening tool for those who merit ultrasound assessment of growth and umbilical artery Doppler.

A case of gestational diabetes arising following treatment with glucocorticosteroids for pemphigoid gestationis.

A case of pemphigoid gestationis, a rare autoimmune disease unique to pregnancy, is described. To control the skin lesions systemic corticosteroids were required. The patient developed gestational diabetes mellitus. The pregnancy continued to 37 weeks and a live male infant was delivered. There was no evidence of macroscopic changes in the placenta. The skin lesions resolved in the postpartum period.

Oncologic rationale for bilateral tonsillectomy in head and neck squamous cell carcinoma of unknown primary source.

OBJECTIVE: To demonstrate an oncologic basis for the recommendation to perform bilateral tonsillectomy as a routine measure in the search for a primary mucosal lesion in patients presenting with cervical nodal metastasis of squamous cell carcinoma (SCC). STUDY DESIGN: A case series of individuals selected from a 3-year period is reported. SETTING: Academic medical center. RESULTS: Each individual presented with metastatic squamous cell carcinoma in a cervical lymph node from an unknown primary source. In each case, the primary source was identified in a tonsillectomy specimen, either located contralateral to the node, or in both tonsils. CONCLUSIONS: The rate of contralateral spread of metastatic cancer from occult tonsil lesions appears to approach 10%. For this reason, bilateral tonsillectomy is recommended as a routine step in the search for the occult primary in patients presenting with cervical metastasis of SCC and palatine tonsils intact.

Metastasizing mixed tumor of the parotid: initial presentation as a solitary kidney tumor and ultimate carcinomatous transformation at the primary site.

Benign mixed tumors of the salivary glands are generally regarded as indolent and harmless neoplasms. A subset of benign mixed tumors, however, can undergo carcinomatous transformation (that is, carcinoma ex-mixed tumor). Even more rarely, a mixed tumor that is seemingly benign at the microscopic level will metastasize like a true carcinoma (that is, metastasizing mixed tumor [MZMT]). Despite the benign appearance of the metastatic implants, there is usually little doubt regarding their true nature and origin. Patients invariably have had a mixed tumor removed from the parotid or some other salivary gland, and metastatic spread is usually preceded by multiple episodes of local tumor recurrence. We report a case of MZMT that presented as a solitary kidney mass. In the absence of a previous or concurrent salivary gland tumor, its metastatic nature was not appreciated and it was regarded as an unusual but benign kidney adenoma. One year after removal of the kidney mass, the patient presented with signs and symptoms of an aggressive parotid tumor. Pathologic examination of the tumor in the parotid demonstrated a high-grade carcinoma arising from a mixed tumor. This case underscores the importance of considering MZMT when a seemingly benign mixed tumor is encountered at a nonsalivary site, even in patients without a supportive history. Failure to do so may cause an unnecessary delay in primary tumor diagnosis and management, allow the primary tumor to progress toward a more malignant phenotype, and deny the patient a high expectation for a complete cure.

Myocardial infarction in critically ill patients presenting with gastrointestinal hemorrhage: retrospective analysis of risks and outcomes.

OBJECTIVES: To determine the frequency of and risk factors for myocardial infarction (MI) in patients admitted to an ICU with GI hemorrhage, and the effects of MI on mortality and length of stay. METHODS: A retrospective review of the medical records of patients admitted to our ICU with GI hemorrhage was conducted. Charts were reviewed for various demographic, laboratory, and outcome parameters. Patients were categorized as having MI, not having MI, or inadequate data to allow classification. RESULTS: Two hundred thirty admissions to the ICU for GI hemorrhage were reviewed. One hundred thirteen cases had serial creatine phosphokinase (CK) measurements with isoenzymes allowing diagnosis of MI. In these 113 cases, patients' mean age was 67.4+/-1.3 years and the mean APACHE II (acute physiology and chronic health evaluation) score was 10.9+/-0.6. The in-hospital mortality rate was 13/113 (11.5%). Patients who did not survive had a higher admission APACHE II score (15.8+/-2.0 vs 10.2+/-0.5; p = 0.02), lower initial systolic BP (104.5+/-4.4 vs 121.2+/-3.2 mm Hg; p = 0.005), and a longer length of ICU stay (8.3+/-1.8 vs 4.0+/-0.4 days; p = 0.04) than those who survived. Sixteen of 113 patients met enzymatic and ECG criteria for MI. One patient complained of chest pain and nine of 16 had shortness of breath and/or dizziness. Patients with MI had significantly more cardiac risk factors (2.4+/-0.2 vs 1.6+/-0.1; p = 0.006), lower presenting hematocrit (26.0+/-1.3 vs 30.5+/-0.8; p = 0.007), and lower lowest hematocrit in the first 48 h (22.3+/-0.9 vs 25.1+/-0.6; p = 0.01), and tended to have a longer ICU stays (7.9+/-2.2 vs 4.0+/-0.4 days; p = 0.09) than those without MI. Patients who had MI were not more likely to die during hospitalization (risk ratio = 1.8; 95% confidence interval, 0.6 to 5.8). CONCLUSIONS: Myocardial infarction occurs frequently in patients admitted to intensive care with GI hemorrhage. A clinical history of and multiple risk factors for coronary artery disease may help identify patients who are at increased risk of MI, which tends to be associated with a higher acuity of illness and in-hospital mortality. Prospective studies are required to further substantiate these associations.
