A 23-year-old woman was admitted with a history of 2 weeks of cough, fever and bilateral lung infiltrates. She had been diagnosed 2 months before as having ulcerative proctitis and was treated with mesalamine, which induced a full remission, but 3 antibiotic regimens failed to improve her lung disease.

Since computerized tomography revealed bilateral peripheral lung infiltrates and her eosinophile count was elevated, the diagnosis of drug-induced eosinophilic pneumonia was suggested. Mesalamine and antibiotics were stopped and oral corticosteroids begun. She became almost asymptomatic a week after mesalamine withdrawal, and the x-ray became normal.

During the August 1998 heat wave in Tel Aviv we admitted many patients for acute heat-related illness; 6 had severe heat stroke and were admitted in critical condition. We describe their clinical courses during the first 5 days of hospitalization, including response to treatment and implications for future management of this disorder.

The mean APACHE II score of the 6 was 30±3.5 and mean Glasgow Coma Scale rating 3.5±0.5; they were in hypovolemic shock and respiratory failure, necessitating mechanical ventilation. Despite early effective therapy (core temperature in all was reduced to less than 398C in less than 1 hour), there was 1 death (mortality 15%) and 4 required further intensive care for life-threatening multiple organ failure.

During severe heat waves a significant number of referrals for acute heat-related illness must be anticipated, possibly overwhelming admission capacity of regional intensive-care units. Severe heat stroke complicated by multi-organ failure is not necessarily related to prior physical activity. Although important in determining prognosis, early treatment does not prevent severe complications. Mechanisms regulating body heat may remain disturbed for days following early treatment and apparent stabilization, mandating continued hospitalization.

An acutely painful and swollen testis mandates urgent diagnostic and therapeutic measures since this symptom complex may indicate torsion of the testis. Prompt scrotal exploration is necessary if the testis is to be saved from ischemic necrosis.

Polyarteritis nodosa (PAN) is a vasculitis involving mainly medium and small sized arteries and may damage any organ. In PAN, the presentation of an acutely painful and swollen testis raises a perplexing diagnostic problem since the symptoms may be related to vasculitis involving the testis on the one hand, or represent primary testicular pathology unrelated to the underlying PAN. A 31-year-old man with PAN who presented with acute pain and swelling in a solitary testis is reported.

The National Institutes of Health (NIH) held a consensus conference which recommended 5-FU and levamisole as adjuvant chemotherapy for colon cancer MAC (Modified Astler Coller) stage C.

From 1991-1994, 37 such patients diagnosed here were treated with 5-FU (intravenous dose of 450/mg/m²/d for 5 days and from day 29, once a week for 48 weeks) and oral levamisole (50 mg 3 times/d. for 3 days, every 2 weeks for a year), as suggested by NIH guidelines.

16 patients were males and 21 were females, mean age was 62 years and median 64. Cancer locations were: right colon (in 16, 43%), left colon (19, 51%), multiple colon primaries (2, 1%). 25 (68%) had 1-3 positive lymph nodes and 12 (32%) had 4 or more positive lymph nodes.

Only 20 (54%) finished treatment as prescribed. In the others, 1 or both drugs caused side-effects for which the drugs had to be stopped. 6 patients relapsed while on treatment.

The most common side-effects were diarrhea, stomatitis and bone marrow suppression. 3 were hospitalized due to neutropenic fever. 5-year actuarial survival of all patients was 61%; 5-year relapse-free survival was 61%; 5-year relapse-free survival of right versus left colon was 41% and 82%, respectively (p<0.01). There was no significant difference in 5-year survival of those with 1-3 positive lymph nodes as compared to those with 4 or more (62% and 56%, respectively). 5-year survival in those who finished or did not finish treatment (excluding those who stopped treatment because of progressive disease) was 83% and 70%, respectively (NS).

The 5-year survival of our series was similar to that of patients treated similarly elsewhere. The 5-FU and levamisole treatment was not tolerated well by our study population. It has recently been replaced in our service by a 5-FU and leucovorin regimen given for 6 months.

Nephron-Sparing Surgery - Initial Experience with 50 Patients

Sarel Halachmi, Alexander Kastin, Boaz Moskovitz, Ofer Nativ

Urology Dept., Bnai Zion Medical Center, Haifa

During recent years the use of the new imaging techniques, ultrasonography and computerized tomography, has increased. The accessibility to these methods has changed the pattern of detection of renal lesions. Over 90% of renal masses are now discovered incidentally, while investigating nonurological symptoms. Therefor, most lesions are discovered in their early stages.

The gold-standard procedure for removing renal masses is radical nephrectomy, which ensures complete removal of an organ-confined lesion, but involves loss of functional tissue. This might be critical in patients with a single kidney, or reduced nephron function. There are several diseases characterized by multiple renal lesions, such as Von Hippel-Lindau and tuberous sclerosis in which radical treatment may lead to chronic dialysis in young patients.

Nephron-sparing surgery was developed in order to preserve as much functional tissue as possible while removing safely any suspicious renal lesion. This new technique, not involving radical surgery, should be evaluated in cases of renal tumors for its ability to achieve the same cancer cures rates. We present our experience with our first 50 patients who underwent nephron-sparing surgery for removal of renal lesions.

Paroxysmal atrial fibrillation (AF), a frequent cause of repeated hospitalization, is effectively treated with propafenone. The time to conversion to sinus rhythm is a consideration when managing AF in the emergency room. We investigated the conversion rates of paroxysmal AF by 3 different oral propafenone (P) regimens, in terms of time to conversion.

188 patients with onset of AF within 48 hours were treated with propafenone (P): 48 received 600 mg as a first oral dose followed after 8 hrs by 150 mg (Group A); 82 received 300 mg as a first dose, followed by the same dose 3 and again 8 hrs later (B); 58 received 150 mg every 3 hrs, up to a total dose of 600 mg (C). P was stopped when sinus rhythm was achieved.

Rates of conversion to sinus rhythm after 3 hrs in the 3 groups were: 46%, 41% and 26% respectively; after 8 hrs: 77%, 78% and 70%; and after 12 hrs: 81%, 84% and 76%. Treatment was discontinued in 8. There was excessive QRS widening (>25% of the basal value) in 1 in group A, 1 in group B and 2 in group C; wide-QRS tachycardia occurred in 4 in group B. In Group A there was a higher rate of early successful conversion, with a lower incidence of side-effects than with the other regimens.

Superficial Skin Necrosis in Short Bowel Syndrome

Arie Eisenman, Rafael Enat

Dept. of Medicine B, Rambam Medical Center and Rappaport Faculty of Medicine, The Technion, Haifa

Short bowel syndrome causes a complex of symptoms due to compromise of small intestinal nutrient absorption. A 60-year-old woman underwent major resection of the small intestine due to a road accident 3 years ago. The sole manifestation of short-bowel-syndrome was superficial skin necrosis due to vitamin K deficiency. She was asymptomatic for a long time, until treatment with antibiotics further intensified initially subclinical malabsorption.

It is not clear why there had been no other symptoms and why the main impact was on the fibrinolytic system rather than the coagulation system, as is usually the case. It is recommended that patients after major resection of the small intestine be closely monitored for coagulation function if an oral antibiotic is prescribed.

Increased thickness of fetal nuchal translucency (TNT) measured at 10-14 weeks of gestation, may suggest underlying fetal chromosomal defects, structural abnormalities or genetic syndromes. We examined the relationship between increased TNT and pregnancy outcome, especially in fetuses with normal karyotypes.

1400 pregnant women underwent first trimester scanning and screening for chromosomal abnormalities and measurement of fetal TNT. 25 fetuses (2%) with increased TNT (>3 mm) were identified. 8 (30%) had an abnormal karyotype. Of these, 5 pregnancies were aborted, 3 ended in spontaneous abortions before karyotyping, and 2 were terminated, all before detailed cardiac scanning. There was a high association between increased TNT and karyotype abnormalities. The total incidence of favorable outcome in fetuses with normal chromosomal and cardiac features but enlarged TNT was 56%.

Combined Sclerotherapy and Surgery for Huge Cervical Lymphangioma

Lymphangioma is a benign developmental anomaly of the lymphatic system located in about 40% of cases in the neck and usually completely resectable. In some cases it invades adjacent structures such as the larynx, pharynx, or tongue. In such cases it is almost impossible to resect completely, as this would endanger vital structures.

We describe a baby born with a huge cervical lymphangioma which invaded the tongue, larynx, pharynx and other cervical structures. He was treated with bleomycin and aethoxysklerol. The sclerotherapy shrank the lymphangioma considerably and it became resectable. At 2 years of age the cosmetic result is good and vital function, such as swallowing and facial expression, are preserved.

It has been shown that the inspiratory muscles of patients with congestive heart failure (CHF) are weaker than normal. This weakness may contribute to dyspnea and limit exercise capacity. But respiratory muscles can be trained for increase in both strength and endurance. This study was designed to evaluate the effect of specific inspiratory muscle training (SIMT) on muscular performance, lung function, dyspnea and exercise capacity in moderate heart failure.

10 patients with CHF (NYHA functional class II-III) received 1/2 hour of SIMT daily, 6 times/week, for 3 months. They started breathing at a resistance 15% of their Pimax for 1 week and the resistance was then increased incrementally to 60%. Spirometry, inspiratory muscle strength and endurance, and the 12-minute walk test were performed before and after the training period. All showed an increase in inspiratory muscle strength and endurance. This was associated with a small but significant increase in FVC, a significant increase in the distance walked (458±29 to 562±32 m, p<0.01), and improvement in the dyspnea index score.

SIMT resulted in increased inspiratory muscle strength and endurance. This increase was associated with decreased dyspnea and an increase in submaximal exercise capacity. SIMT may prove to be useful complementary therapy in CHF.

The renin-angiotensin system is thought to play an important role in the pathophysiology of kidney disease in diabetes. Previous studies have shown a possible association between the D allele of the angiotensin converting enzyme (ACE) gene, known to be associated with higher circulating levels of ACE, and increased risk of developing nephropathy in NIDDM. The present study investigated the distribution of ACE gene genotypes in the general population and patients with NIDDM, the association between the D allele and diabetic nephropathy, and the association between the ACE genotype and involvement of other target organs in NIDDM. The ACE genotype (insertion/deletion I/D) was determined in all subjects, subsequently divided into 3 groups based on their polymorphism (DD, DI and II). The presence of nephropathy was defined by an albumin-creatinine ratio of 30 mg/g or greater (mean of 2 first morning urine samples).

In the general population most had the D allele (DD or ID) and a minority the II genotype. There was no association between genotype and hypertension, ischemic heart disease, hyperlipidemia, and cerebrovascular or peripheral vascular disease. In diabetics the genotype distribution was not different from that in the general population. Within the diabetic group, there was no association between genotype and hypertension, hyperlipidemia, duration of diabetes, or HbA1C levels. Nephropathy, found in 81 of the 156 with NIDDM, was not associated with genotype. Diabetic nephropathy was not associated with retinopathy, neuropathy, or ischemic heart, cerebrovascular or peripheral vascular disease. We conclude that in the population sampled, there was no association between the D allele of the ACE gene and the risk of developing nephropathy in NIDDM.

Malignanhidradenoma is a very rare tumor that originates from sweat glands. We present a 61-year-old man with an ulcerated tumor in his right flank, 4 cm in diameter, that was excised with a wide free margin. Histopathologic study showed an ill-defined, epithelial neoformation, formed by lobules of clear polygonal cells in the deep dermis and subcutaneous tissue, diagnosed as malignant nodular hidradenoma.

1.5 years after excision there was enlargement of the right axillary and inguinal lymph nodes, which showed metastatic, adnexal neoplastic cells. Axillary resection and superficial dissection of the right inguinal nodes were performed. After 3 months the tumor had spread to other lymph nodes and acute obstructive renal failure required insertion of a pig-tail catheter into the right ureter. Radiotherapy was followed by chemo-therapy, but he died from end-stage metastatic disease in multi-organ failure.

To determine the results of the conservative approach in the treatment of pediatric abdominal trauma, we retrospectively analyzed data from the files of 95 cases of abdominal trauma in children during a 5-year period.

51 patients (54%) had isolated abdominal injury, while 44 (46%) had multiple trauma. The most common causes of injury were road accidents and falls from heights (74%). CT scans were performed in 61 (64%) with positive results in 90%. Ultrasonography was done in 22 (23%) and was positive in 55%.

The spleen was the most vulnerable intra-abdominal organ (33 patients, 35%), as well as the organ most severely damaged. Other injured organs were: liver (30 cases), kidney (16), stomach (2), large blood vessels (2), and pancreas, duodenum and diaphragm (1 case each).

83 patients (87%) were treated conservatively, while 11 were operated on for penetrating abdominal trauma (3 cases), hemodynamic instability (3), positive DPL (3), and Scale 4 splenic injury and free intra-abdominal air on CT scan (1 case each). Early and late complications were mild.

It is concluded that CT is an efficient and reliable imaging method for diagnosis and staging of severity of injury in blunt abdominal trauma. Nonoperative management of solid organ injuries under careful observation in a pediatric trauma center is safe and appropriate. Most Scale 4 splenic injuries can be treated successfully without surgical intervention. Using this conservative approach there were no late complications.

Major pancreatic trauma challenges the trauma surgeon with diagnostic problems and choices of treatment modalities. The most important determinant guiding management is the integrity of the main pancreatic duct. The preoperative and intraoperative assessment and treatment of pancreatic injury may be difficult, especially when concurrent severe injuries are present. There are alternative approaches in the management of the traumatized pancreas when ductal injury is not obvious during initial exploratory laparotomy.

We performed 75 laparoscopic cholecystectomies during July and September 1996. In 3 men and 4 women, aged 32-87 years, there was obstructive jaundice caused by choledocholithiasis. During laparoscopy in the jaundiced patients, calculi were identified by cholangioscopy and intra-operative cholangiography. They were washed into the duodenum (confirmed cholangiographically) after intravenous glucagon injections and dilation of the papilla of Vater.

Serum bilirubin and liver enzyme levels returned to normal within a few days. There was no operative or postoperative morbidity, nor any biliary-related systemic complications. Average postoperative hospitalization was 3 days.
