        Multilocular Cystic Mass of the Kidney: A Diagnostic Challenge

        Urology Dept., Assaf Harofeh Medical Center, Zerifin

         

        Multilocular cystic masses of the kidney present a diagnostic challenge because they may be malignant. Renal cell carcinoma with multilocular cysts has been reported. We present 4 cases in which the preoperative differential diagnosis was between a benign and a malignant multilocular cystic kidney mass.

        Our results, combined with those of 33 previously reported cases, reveal that only 32% of cases were diagnosed correctly preoperatively. In 21% of these patients the preoperative clinical evaluation did not correctly diagnose malignancy: 24% of them yielded false negative and 21% false positive results. Angiography was more accurate than CT, US or aspiration of cysts. Frozen section was inaccurate in 55% of cases.

        There is no reliable diagnostic test to distinguish between a malignant and a benign multilocular cystic mass. Invasive angiography is more accurate than other modalities. A therapeutic decision has to be made between nephron-sparing and radical surgery in each case. When nephron-sparing surgery is considered, the possible need to perform radical nephrectomy in second-look surgery must be taken into account.

        Irritable bowel syndrome is a group of heterogenic complaints of functional bowel disorder in the absence of organic pathology. The pathophysiology is unclear. In most cases treatment includes symptomatic remedies, antidepressants, psychotherapy and hypnotherapy.

        Biofeedback has recently been introduced as a therapeutic modality. Treatment also includes relaxation techniques and guided imagery, together with computer-assisted monitoring of sympathetic arousal. Biofeedback requires active participation of patients in their healing progress and leads to symptom reduction in 2/3.

        Urethral catheterization, the standard method of measuring residual urine, is uncomfortable and associated with risk of infection and trauma to the urethra. It has also been reported as inaccurate to a certain extent. We compared catheterization with ultrasound scanning in a prospective study of 52 men and 3 women.

        100 measurements of postvoiding residual urine by portable ultrasound scanner, were each followed immediately by urethral catheterization (both procedures performed by an experienced nurse in our outpatient clinic). A difference of >25€ml between measurements by scanner and by catheter was considered significant.

        The range of residual urine measured by scanner was 1-425 ml, and by catheter 1-410 ml. There was good matching between the 2 methods in 85 of 100 measurements (scanning accuracy 85%). In 30/85 matching was excellent while in 55 cases the mean difference was 8.5±6.2 ml, range 1-24 ml. The accuracy of scanning was 85%; there was perfect matching between the 2 methods in 30 cases. In the remaining 15 cases the mean difference was 41.8±13.6 (range 25-56).

         

        Each catheterization took 4-5 minutes and scanning 30 seconds. There were no complications after catheterization, but all reported discomfort and dysuria for 1-2 hours thereafter. Scanning was absolutely uneventful in all.

        The cost per catheterization, including medication, disposable materials and personnel time was approximately 80 NIS. Our 80-90 measurements of residual urine a month require annually about 80 hours and a budget of about NIS 80,000. Scanning requires only 8 hours, while the cost of the portable scanner is significantly less than NIS 80,000 and it can be used for more than a year.

        We conclude that measuring urine residual with the noninvasive scanner instead of by catheterization is easier, more accurate, and more cost-effective.

        The safety and efficacy of Amlodipine (AML) for mild to moderate hypertension was evaluated in a "real life" setting. This open non-comparative trial included 123 men and 143 women (age 30-91 years, mean 59.4). All had sitting diastolic blood pressure (DBP) between 95 and 115 mmHg, confirmed in most by 2 baseline measurements, 2 weeks apart.

        Eligible patients were given AML 5 mg daily as add-on or monotherapy and were evaluated 4 weeks later. If DBP was then >90 mmHg, the daily dose was raised to 10 mg; those with <90 mmHg remained on 5 mg. AML was continued for 8 weeks. Other BP-lowering drugs were unchanged.

         

        Of the original 266 patients 22 (8.2%) withdrew due to adverse events (AE), and others were protocol violators, lost to follow-up or withdrew, leaving 211 available for efficacy analysis. In this major group BP was reduced from 165±15/101±4 to 139±11/83±5 after 12 weeks of AML (p<0.05). The reduction was greater in those under 70 years, from 173±12/100±5 to 142±12/80±4 (p<0.05). In those with BMI>30 kg/m², BP decreased from 165±15/101±5 to 140±12/83±5 (p<0.05).

         

        Mean change in heart rate was -1.5 bpm (p<0.05). Mean final AML dose was 5.5 mg/day. The most common AML-related AE requiring cessation of the drug was pedal edema in 2.6% of the 266 patients; in 3.7% it persisted during therapy. Other AE occurring in >1% were dizziness in 1.8%, headache 1.5%, flushing 1.1% and fatigue 1.1%.

        We conclude that AML is an effective and well-tolerated antihypertensive suitable for most hypertensive patients.

        Mirena, a new intra-uterine device (IUD) introduced in Israel during the past year, releases 20 mcg/day of levonorgestrel for 5 years. It has the advantages of reduced pregnancy rates and diminished menstrual blood loss, together with a low risk of pelvic inflammatory disease compared with current IUD's.

         

        It has a typical sonographic appearance, differing from that of regular IUD's, which was demonstrated in all 15 women examined in this study. Its sonographic appearance includes both proximal and distal ends of the vertical arm of the device, which extend into the internal cervical os and fundal region, respectively. Acoustic shadowing between both ends defines the location of the device, which should help avoid consultations due to "lost IUD's."

        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.

        There has been an increased incidence of malaria among Europeans returning from Africa and Asia. The relatively new antimalarial mefloquine (Lariam) has become extremely popular due to its efficacy in treatinthe wide-spread chloroquine-resistant Plasmodium falciparum.

         

        Mefloquine is used both for prophylaxis and treatment of malaria and is relatively well tolerated. However, since introduced in 1985, there have been over 100 reports of severe neurologic and psychiatric adverse effects associated with its use, including acute psychosis, affective disorders, acute confusional states and seizures.

         

        We describe a 39-year-old woman who developed acute psychosis after being given mefloquine prophylaxis. Adverse effects occur more often after therapeutic rather than prophylactic use, and those with a history of seizures or psychiatric illness are at increased risk of developing these reactions. Physicians should be aware of these possible side effects and prescribe mefloquine only when indicated.

        We assessed the prevalence of self-reported medical complaints among the community-dwelling elderly receiving regular medication, and determined associations between health and sociodemographic variables, and the prevalence of complaints.

         

        The study included 170 patients, 60-90 years of age, living at home. Participants were recruited from the 3 main primary care clinics in Rishon LeZion. All were receiving chronic medication and were followed-up utilizing a long-term medication card. Data were gathered in interviews held in patients' homes using a structured questionnaire which included sociodemographics, diseases and medication, mental state assessment by Katzman's score, and a list of 15 medical complaints common among the aged. Relations to age, gender, education, living arrangements, number of diseases and number of medications per patient were determined.

         

        Mean age of participants was 73.2±6.0 years and they suffered an average of 4.07±2.16 diseases and took 5.10±2.83 types of drugs. The most prevalent complaints were: weakness and fatigue (65.0%), agitation and restlessness (56.4%), dry mouth (45.6%), constipation (43.6%) and dizziness (43.2%). The number of diseases, gender, education and age had the strongest associations with the prevalence of specific complaints, as well as their total number. The association between number of medications and mean number of complaints was of borderline significance.

        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.

        2 women, aged 31 and 37 years, respectively, suffered from acute febrile illness due to acute infection with human parvovirus B19. 1 also had a maculopapular rash and articular symptoms after her fever stopped, a clinical picture typical of erythema infections. The other had leukopenia and thrombocytopenia and had received dipyrone. Although acute infection with human parvovirus usually occurs in childhood, it may also occur in adults, with protean manifestations.

        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

        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.

        Sudden low back pain is common in elderly women. It causes physical and mental stress, and results in deterioration of functional movement and in activities of daily living. Awareness of possible sacral insufficiency fracture is important; they may be demonstrated by imaging modalities, mainly radionuclide bone scan. Prognosis is good and accurate diagnosis serves to exclude malignancy and relieve fear of chronic pain and disability. We describe 4 women, aged 84, 82, 71 and 77 who illustrating the clinical and imaging findings of this disorder.
