Today Fournier's gangrene ranks among necrotizing fasciitis. Most of the cases reveal the origin of the disease (proctogenic, urologic, gynecologic). Untreated, the polybacterial synergistic infection will overwhelmingly spread along anatomically defined fascias of the pelvic floor. Thus the lethality rate is high, especially in patients with risk factors i.e. diabetes, alcoholism, arterial occlusive disease, chronic consumptive disorders and obesity. Only by instant and radical surgical excision of the total gangrenous tissue the spreading of the disease and the developing of sepsis can be stopped together with calculated antibiotic therapy and intensive care. Mutilating operations (i.e. penectomy, orchiectomy) are seldom necessary; thus plastic reconstructions will show good results both in function and cosmetic. Based on the experience with 6 patients, a pathogenic concept, concerning both diagnosis and therapy, is presented: after radical emergency surgery in the first risky stage, an elective approach can safely be performed in a second stage for the repair of functional lesions.

The elderly are more liable to problems from drugs used systemically. An accurate diagnosis may reveal conditions in which drug treatment is not required, especially those due to faulty habits and environmental problems, and local conditions susceptible to injections or surgery. Obesity, sepsis, hypothyroidism, osteomalacia, unsuspected fractures and drug side-effects may give correctable rheumatological problems. Use of analgesic anti-inflammatory drugs needs great care in the elderly; use analgesics instead when possible. Rheumatoid arthritis in the elderly demands maximum use of nonpharmacological treatment and local treatment. Analgesic anti-inflammatory drugs should be used carefully and sparingly. Use slow-acting drugs as in younger patients.

Normal human ageing is associated with changes in body composition which include a decrease in muscle mass and strength, bone mass loss and increase in adipose mass. A physiological decrease in growth hormone (GH) and IGF-I secretion accompanies these changes. Many of the physiological changes that accompany normal human ageing are very similar to those found in GH deficient patients. Nevertheless, responsiveness to exogenous administered GH persists with advancing age. GH administration to elderly individuals has produced an decrease in fat mass and an increase in lean body mass, being this finding consistent with the hypothesis that GH deficiency could be a contributing cause to senescent changes in some elderly individuals. GH treatment has also been used with encouraging results in adult subjects with isolated or combined GH deficiency. On the other hand, several clinical studies have recently shown the efficiently of GH treatment on diverse pathological processes such as severe catabolic states (surgery, sepsis, trauma, buns), osteoporosis, diabetic ulcers and obesity. The most frequent side effects are sodium and water retention, impairment in glucose tolerance and carpal tunnel syndrome, although in general the treatment has been well tolerated. The clear definition of the therapeutical applications of GH in the adult warrants further clinical investigation.

Some conditions that predispose to ventilatory failure increase the work of breathing (chronic obstructive pulmonary disease [COPD], obesity, kyphoscoliosis), whereas others cause severe respiratory muscle weakness. Specific reasons for muscle weakness include critical illness (electrolyte imbalance, acidemia, shock, sepsis), chronic illness (poor nutrition, cachexia), and neuromuscular diseases. Inspiratory muscle weakness from mechanical disadvantage to the diaphragm is characteristic of asthma and COPD. The increased work of breathing combined with muscle weakness increases the pressure needed to inspire a breath and decreases maximal inspiratory pressure. When this pressure exceeds 0.4, dyspnea and inspiratory muscle fatigue ensue. One way to lower this pressure and avert fatigue is to lower the tidal volume. Ventilatory drive is high, not low, in ventilatory failure. Concomitant shortening of inspiration and breath duration cause the small tidal volume and increased respiratory rate. Gas exchange is compromised by ventilation/perfusion imbalance, and the ratio of dead space to tidal volume is also increased by rapid, shallow breathing. Reduction in tidal volume minimizes dyspnea, but the small tidal volume is inadequate for gas exchange. Acute treatment of respiratory muscle failure involves respiratory muscle rest through mechanical ventilation and removal of noxious influences (infection, metabolic disarray), whereas chronic treatment involves rebuilding the contractile apparatus by nutritional repletion and training.

The pattern of postoperative pyrexia in Khartoum was prospectively studied in 260 patients who underwent a variety of surgical operations. Ninety four patients (36.1%) developed postoperative pyrexia. The commonest causes of pyrexia encountered were wound sepsis (10%), malaria (9.6%) and respiratory tract infection (7.3%). Less frequent causes were urinary tract infection, thrombophlebitis, intra-abdominal sepsis and deep vein thrombosis. In 14.6% of the patients, the cause of pyrexia was undetermined. The risk factors for postoperative pyrexia were the patient's age, diabetes mellitus, obesity, preoperative chest infection, smoking, duration of surgery, operator's surgical experience and urethral catheterisation. The postoperative pyrexia was associated with 7.4% mortality rate which was due to intra-abdominal sepsis and pulmonary embolism. The incidence of postoperative pyrexia can be minimised by adequate preoperative preparation, meticulous surgical technique and good postoperative care.

Adiposity of the heart is characterized by an increase in the amount of epicardial and other adipose tissue. The most pronounced changes involve the right ventricle. The adipocytes may be interposed between myocytes, and in severe cases the normal mechanics and function of the ventricle are impaired. Adiposity of the heart is usually an incidental finding at autopsy, and only rarely is it of clinical significance. This report describes a 46-year-old female with multiorgan failure secondary to bronchopneumonia, purulent pericarditis, tamponade and sepsis, whose clinical course was altered due to severe adiposity of the heart, so-called 'adipositas cordis'.

We assessed the clinical characteristics of newly-diagnosed diabetic patients presenting to the Mulago Hospital Diabetic Clinic for the first time between 1 January 1993 and 10 August 1994. There were 252 patients: 117 men and 135 women. Mean age at onset of diabetes was 45 years (range 2-87 years) and peak incidence was at 40-49 years. Body mass index (BMI) was available in only 71 patients, of whom 53.5% (33.8% female, 19.7% male) were overweight (BMI > 25 in women, in > 27 men) and 11.3% (8.5% men, 2.8% women) were underweight (BMI < 20). Obesity was more marked in young women. Almost all patients presented with the classical symptoms of diabetes, and the majority were severely hyperglycaemic. A family history of diabetes was identified in 16%. Concurrent illnesses at diagnosis of diabetes were unusual. Sepsis was commonest (11.9%), followed by malaria (7.8%), tuberculosis (1.2%), AIDS (1.2%) and pancreatitis (0.8%). Peripheral neuropathy was present in 46.4% of patients, hypertension (BP > 150/100) in 27.3%, impotence in 22.2% of the men, proteinuria in 17.1%, ischaemic heart disease in 4.8%, foot ulcers in 4.0% and cataracts in 3.2%. Insulin was the most commonly prescribed treatment (52.8%); 31% of patients received oral hypoglycaemic agents, only 15.1% were managed on diet only, and 1.2% opted for herbal medicine.

In a German multicenter survey, 2206 gynaecological patients in 72 randomly selected hospitals were examined for the prevalence of nosocomial infections and possible risk factors. Hospital-acquired infections were diagnosed in 1.45% of the patients. The most common localisation was the urinary tract (0.91%). Septicaemia, vaginitis and infections of the upper and lower airways were only rarely seen. The following endogenous risk factors were identified: diseases of the cardiovascular system (16.1%), malignancies (12.2%) preexisting infections (6.1%), obesity (5.9%), and diabetes (5.0%). The most common exogenous risk factors were peripheral venous catheters (19.9%), catheterisation of the urinary tract (7.2%) and wound drainage (28.6%). 49% of the patients who underwent caesarean section and 50% of the hysterectomy patients received antimicrobial chemoprophylaxis.

The purpose of this study was to determine the characteristics of gouty arthritis in an urban Guatemalan population. We reviewed the medical records of 148 (145 males and 3 females) patients with a diagnosis of acute gouty attack seen at an urban rheumatology clinic in Guatemala City between 1982 and 1993. Mean age at diagnosis was 49 years (range 21-87), mean age of onset was 42 years, mean duration of disease 7.4 years, family history of gout 42 (28%), peak prevalence 5th decade 39 (26%). Seventy-one (48%) had monarticular, 49 (33%) oligoarticular, and 22 (15%) polyarticular attacks, respectively. Podagra was seen in 34 (23%) patients; however, 108 (73%) developed it at any moment of their life. Tophaceous gout was seen in 33 (22%). Mean serum urate concentrations (enzymatic method) were higher than 7.0 mg % in 90 (60%) patients. At follow-up, 44 (30%) patients never returned to our clinic, and a large majority of them [66 (45%)] were seen only during acute attacks. Associated disorders included hypertension (43%), obesity (27%), nephrolithiasis (16%), ischaemic heart disease (7%), renal insufficiency (2%), stroke (0.6%), and diabetes mellitus (0.6%), and two died due to sepsis; high alcoholic intake was found in 58 (39%) patients. In conclusion, our findings indicate that gout is not an unusual disorder in the Guatemalan population. It presents with the same characteristics as those reported in Caucasians, with the possible exception of a lower frequency of diabetes mellitus as an associated disorder.

Questionnaires were mailed to 620 U.S. "trauma surgeons" to determine a consensus regarding indications for inferior vena caval (IVC) filter placement; 210 (34%) responded. Eighty-seven percent of respondents practiced in Level I trauma centers; 78% were in urban areas and 75% reported more than 1,000 trauma admissions per year. One-half (52%) of those responding were "trauma directors" at their centers. Filter insertion was done by radiologists at 81% of centers, by trauma surgeons at 34%, by vascular surgeons at 33%, and by general surgeons at 13%. Each month, 60% of trauma centers inserted zero or one filter, whereas 27% inserted two to three filters. Complications per year were reported as one or fewer in 85% of trauma centers. Respondents agreed that "absolute indications" for inserting IVC filters were pulmonary embolism while anticoagulated (93%), deep venous thrombosis present and anticoagulation contraindicated (89%), and free-floating ileofemoral thrombus by venogram (54%) and by duplex imaging (45%). "Relative indications" for placement were deep venous thrombosis by duplex imaging (41%) or by venogram (38%), spinal cord injury (40%), pelvic fractures (39%), multiple lower-extremity fractures (29%), concurrent cancer (19%), prolonged bed rest (14%), and obesity (10%). The permanent nature of the filter affected its rate of application. For example, potential removability would significantly (p < 0.01) increase prophylactic placement from 29 to 53% in the patient with multiple lower-extremity fractures. Only 12% considered sepsis and 10% young age as contraindications to IVC filter insertion. Contraindications and complications were few, yet frequency of use was surprisingly low. Radiologists insert the filter more than twice as often as surgeons.
