Association between varicocele and chronic obstructive pulmonary disease.

PURPOSE: To evaluate the relationship between varicocele and chronic obstructive pulmonary disease (COPD) via color duplex sonography. MATERIALS AND METHODS: Forty-four male patients with COPD (age range, 50-89 years; mean +/- SD, 66 +/- 9) and 44 male healthy controls (age range, 47-75 years; mean +/- SD, 65 +/- 6) were evaluated with color duplex sonography for unilateral or bilateral varicocele. RESULTS: The incidence of right, left, and bilateral varicocele was 47.7%, 65.9%, and 38.6% respectively, in the COPD group, versus 22.7%, 52.3%, and 13.6% in the control group. The incidence of right and bilateral varicocele in the COPD group was significantly higher than in the control group (p < 0.05). The incidence of varicocele also increased with increase in COPD severity. CONCLUSIONS: The incidence of varicocele in COPD patients is high. Varicocele might be one of the most important causes of scrotal pain and infertility in COPD patients.

The prevalence of venous insufficiency in patients with chronic obstructive pulmonary disease evaluated by color duplex ultrasonography.

OBJECTIVES: We hypothesized that in patients with chronic obstructive pulmonary disease (COPD) some extrapulmonary effects such as increase in intra-abdominal and intra-thoracic pressures, presence of cor pulmonale and pulmonary artery hypertension could cause venous insufficiency (VI) in the lower limbs. Our aim in this study was to assess the prevalence of VI in patients with COPD in comparison with healthy controls. METHODS: Thirty-nine male patients with COPD and 36 healthy male controls were evaluated for VI. All the participants were in the same age group and their smoking intensities were similar. Patients with COPD were classified as having mild, moderate, severe or very severe disease according to criteria of the Global Initiative for Chronic Obstructive Lung Disease. All the patients and control group were examined for unilateral or bilateral VI of the common femoral vein, superficial femoral vein, deep femoral vein and popliteal vein using color duplex ultrasonography. RESULTS: The prevalence of VI of the lower extremity in patients with COPD (69.2%) was significantly higher than in the healthy control group (41.7%). The prevalence increased as the COPD severity increased and VI was detected in all the patients with very severe COPD [mild COPD, 50.0% (2/4); moderate, 58.8% (10/17); severe, 75.0% (9/12); very severe, 100% (6/6)]. CONCLUSION: VI of the lower extremity appears more frequent in patients with COPD. We suggest ruling out COPD in patients with otherwise unexplained "primary" VI.

Laryngocele in association with ankylosing spondylitis.

A laryngocele is a cystic dilatation of the laryngeal saccule. The etiology of laryngoceles is unclear, but congenital and acquired factors are considered to play a role in their development. An acquired laryngocele may develop when the laryngeal ventricle becomes functionally obstructed as a result of an increase in intraglottic pressure, such as that caused by excessive coughing, playing a wind instrument, glass blowing or obstruction of appendicular ostium. We present a case of laryngocele in a patient with ankylosing spondylitis. To the authors' knowledge, and from a review of the literature, this combination has not been previously described. The laryngocele was also infected in this case. We believe that development of the laryngocele might be a result of increased intra-abdominal pressure, caused by rheumatoid arthritis, with associated increased intralaryngeal pressure.

Measuring the correlation between adenoidal-nasopharyngeal ratio (AN ratio) and tympanogram in children.

OBJECTIVE: To evaluate the correlation between adenoidal-nasopharyngeal ratio (AN ratio) and tympanogram in children. STUDY DESIGN: A prospective clinical study from June 2002 to May 2003. METHOD: A total of 64 children, aged 6-9 years who presented with nasal obstruction, snoring, mouth breathing, and hyponasal speech were examined and AN ratio was calculated by using the lateral neck radiograms and compared with the tympanometric values. The relationship between AN ratio and middle-ear pressure was evaluated, regarding the AN ratio of 0.71. The chi-square test was used to analyze the correlation between AN ratio and middle ear pressures and Wilcoxon test was used to compare the changes between the mean AN ratio values, and mean middle ear pressures (including A and C type tympanograms) before and after medical therapy. RESULTS: Middle-ear effusions and C type tympanograms in impedance audiometry were both related to eustachian tube dysfunction resulting from enlargement of the adenoids with AN ratios higher than 0.71. Middle ear pressures were found lower in children with AN ratio greater than 0.71 than in children AN ratio less than 0.71 and the difference was highly significant (p<0.001). Although medical treatment of large adenoids was rather effective to shrink the adenoid tissue (p<0.001), it did not cause a statistically significant change in tympanometric values (p>0.05). CONCLUSIONS: Antibiotherapy is effective in reducing adenoid size without signs and symptoms of infection. The reduction of the adenoids in size after 3 weeks of antibiotherapy has an positive effect on recovery of eustachian tube function but is not sufficient in patients with middle ear effusion. Early ventilation tube insertion may be an alternative therapy for the middle ear effusions not improving by 3 weeks medical therapy.

Latent fatality due to hydatid cyst rupture after a severe cough episode.

Hydatid disease is a parasitic disease caused by Echinococcus granulosus characterised by cyst formation in various organs. The infestation mostly involves the liver. Hydatid cysts of the liver can rupture either spontaneously or due to trauma. Incidence of rupture is about 3-17% of all cases with hydatid disease. Unless treated surgically, rupture can result in death. Here, we present a case of hydatid cyst ruptured after a severe cough episode and disseminated first to the subcapsular area, then to the peritoneal space. Probably due to a decrease in parenchymal pressure in the liver after decompressive effect of rupture, the patient felt an improvement in abdominal pain, refused operation, and left the hospital on his own responsibility. This unfortunate relief resulted in a delay of 55 hours in management. The leakage of liquid materials into peritoneal space resulted in a severe inflammatory reaction and eventually death of the patient. The patient died of a late peritonitis rather than anaphylaxis, which is the most common reason for death in such patients. As a conclusion, physicians should be aware of a temporary relief in abdominal pain after cyst rupture that may cause a delay in management and in turn loss of patient due to peritonitis.

Cerebral blood flow measurements of the extracranial carotid and vertebral arteries with Doppler ultrasonography in healthy adults.

PURPOSE: To establish normal cerebral blood flow volume by measuring flow volume of the extracranial carotid and vertebral arteries using Doppler ultrasonography in healthy adults. MATERIALS AND METHODS: A prospective study was performed with a group of 96 healthy adults aged 20 to 80 years (48 women, 48 men; mean age of all patients, 49.8 +/- 17.1). The common, external, and internal carotid arteries and the vertebral arteries (CCA, ECA, ICA, and VA, respectively) were examined using Doppler ultrasonography. Peak systolic velocity (PSV), end diastolic velocity (EDV), resistive index (RI), and luminal diameters of the vessels were measured, and flow volumes were calculated in all the arteries. The influence of age on these parameters was also investigated. RESULTS: In the CCA, ICA, and VA, all flow velocities and flow volumes decreased significantly with an increase in age. The luminal diameters of the carotid and vertebral arteries increased significantly with aging, while there was no significant alteration in the RI. The luminal diameters of the CCA, ICA, and ECA were significantly smaller in women than in men. PSV and EDV in the ICA, and EDV in the VA were significantly higher in men. There was no gender-linked difference in flow volumes of the brain-feeding arteries, however, in the ECA flow volumes were significantly higher in women. CONCLUSION: Normal cerebral blood flow volume was established by measuring the flow volume of the ECA and VA with Doppler ultrasonography in healthy adults. We believe that these data can be useful in evaluating cases with cerebrovascular disease, which are related to altered cerebral blood flow volume.

Multiseptate gallbladder with acute acalculous cholecystitis.

Multiseptate gallbladder is a rare congenital malformation of the gallbladder. In some cases, right upper quadrant pain, recurrent abdominal pain, and gallstones were present. We present the sonographic findings in a case of multiseptate gallbladder with acute cholecystitis, which (to our knowledge) has not been reported before. We hypothesize that bile sludge accumulated and subsequent cholecystitis developed as a result of bile stasis in our case because the classic predisposing factors that have been described were absent.

Clinical and ultrasonographical findings in patients with multiseptate gallbladder.

Multiseptate gallbladder is one of the rare congenital malformations of the gallbladder. We present clinical and ultrasonographic findings in seven patients with multiseptate gallbladder. One of them had nausea and right upper quadrant pain, three had recurrent abdominal pain, while the remaining three patients had no symptoms, physical finding and laboratory abnormality which could be attributable to the biliary system. In patients with multiseptate gallbladder, disturbed motility of the gallbladder may be an etiopathogenetic factor for stasis of bile flow and in turn for development of cholelithiasis, cholecystitis and right upper quadrant pain.

Intima-media thickness of the common carotid artery in highway toll collectors.

PURPOSE: To assess the effects of exposure to exhaust particles on intima-media thickness of the common carotid artery in highway toll collectors. METHODS: Sixty-one highway toll collectors (HTCs) between 24 and 56 years of age (mean, 36.2 +/- 7.3) and 48 controls between 24 and 64 years of age (mean, 42.6 +/- 10.6) were evaluated with gray-scale sonography to measure intima-media thickness (IMT) of the common carotid artery (CCA). Subgroups were categorized according to duration of exhaust exposure and further divided according to tobacco use. RESULTS: CCA IMT was higher (0.8 +/- 0.2 mm) in HTCs than in the control group (0.6 +/- 0.1 mm; p < 0.001) and remained higher when subgroups with similar smoking habits were compared. In HTCs, IMT was greater when the number of years working in tollbooths was greater (p = 0.023). IMT was lower in HTCs with an exposure duration of < 10 years compared with a duration of 10-20 years (p = 0.017) or > 20 years (p value not significant). CONCLUSION: Air pollution has a widely acknowledged negative effect on humans. This study confirms that exposure to exhaust particles might cause wall thickening of carotid arteries.
