ABSTRACT: Lung herniation is a relatively rare clinical entity that is most commonly either congenital or acquired traumatically. We describe a case of spontaneous lung herniation secondary to acute cough in an obese male smoker complicated by contralateral acute lung injury and systemic inflammatory response syndrome (SIRS). Mechanisms of lung herniation, classification, diagnosis, and management will be discussed.Clinical medicine insights. Case reports. 01/2011; 4:39-42.

ABSTRACT: Tendon transfers are performed predominantly to restore hand function or balance due to injuries of the radial, median, and ulnar nerves. Current surgical techniques for the most common tendon transfers for reconstruction of radial, median, and ulnar nerve palsies are demonstrated. These techniques can also be applied to restore flexion and extension of the fingers and thumb after injuries to the extrinsic flexor and extensor muscles and tendons of the forearm or intrinsic muscles of the hand.Clinics in plastic surgery 10/2011; 38(4):621-42. · 0.95 Impact Factor

ABSTRACT: The authors present two cases of atraumatic (spontaneous) thoracic lung hernias, which are extreme rarities in the international literature, too. Risk factors and clinical pictures discussed and operative treatments are demonstrated. The spontaneous thoracic (intercostal) hernias were provoked by intractable cough caused by chronic obstructive pulmonary disease (COPD) in both cases. Multi-slice spiral CT (MSCT) scan as well as the secondary 3D 'volume rendering' (VRT) reconstructions unequivocally suggested this rare condition. Provided with the exact diagnosis, the surgical correction of the thoracic wall resulted in full recovery of the two patients. Finally, the authors briefly discuss data of thoracic hernias published in the Hungarian and the international literature. They conclude that the awareness of this extremely rare condition is important due to the high prevalence of COPD as a risk factor. Diagnostic imaging demonstrated can provide significant help in the correct diagnosis of similar cases.Magyar Sebészet (Hungarian Journal of Surgery) 04/2010; 63(2):80-3.

A 48-year-old man had been diagnosed with severe chronic obstructive pulmonary disease and
referred to our pulmonary clinic. His medical history revealed a 60-80 pack year smoking history
and long-standing heavy alcohol consumption. He worked as an upholsterer, with exposure to
glues and paints for 20 years. Tuberculin skin testing was negative with a positive Candida con-
trol. Sputum Gram-stain revealed many polymorphonuclear leukocytes and was AFB-stain posi-
tive. Culture growth indicated mycobacterium other than tuberculosis identified as Runyoun's
Group III. Drug sensitivity testing demonstrated 0% resistance to the combination of isoniazid,
rifampin, and ethionamide.
His clinical condition gradually deteriorated despite antimicrobial therapy. Pulmonary function
testing in 1994 demonstrated severe obstructive lung disease with a DLCO of29% predicted (8.5
ml/min/mmHg). One month later, he developed acute bronchitis and during a severe coughing
spell he noticed the acute onset of bulging of his left anterior chest wall. The bulge rapidly
expanded during manoeuvres which increased intrathoracic pressure and rapidly reduced with
cessation of these manoeuvres. In addition to the expansion and contraction of this chest wall
bulge, physical examination was remarkable for sonorous breath sounds and the sound of
'gurgling' fluid within the bulge. A chest X-ray is shown in figure 1. A chest computed tomogra-
phy (CT) scan (figure 2) was obtained in the semi-prone position during a Valsalva manoeuvre.

The chest X-ray demonstrated hyperinflation,
severe bullous emphysema, and cavities con-

change in the left lung and a small cavity in the
right lung. The arrow indicates herniation of a
large bulla through the left anterior second and
third rib interspace.
The diagnosis is spontaneous intercostal her-
niation of a lung bulla.

comprehensive and often
literature. The classification describes lung
herniation according to location - cervical,
thoracic, or diaphragmatic - and according to
aetiology - congenital or acquired. Acquired
lung hernias are further divided into traumatic,
consecutive, spontaneous, and pathological.
Only one case of diaphragmatic lung hernia-
tion has been described.'
The term consecutive hernia is confusing; it
was used to define those hernias developing
some time after a focal chest wall injury. These
cases should be categorised
Pathological hernias develop secondary
neoplasm or infection involving the chest wall.

The thorax has three sites of relative anatomic
weakness, and these are the most common sites
ofcongenital and spontaneous lung herniation.
In the cervical region, there is a relatively
unsupported region between the sternocleido-
mastoid and the anterior scalene muscles. In
the intercostal spaces, there are two areas of
anatomic weakness created by the absence of
musculature. The external intercostal muscles
extend from the rib tubercles posteriorly to the
beginnings of the costal cartilages anteriorly.
From there, they continue along the costal car-
tilage as the anterior intercostal membranes.
The internal intercostal muscles extend from
the sternum to the angles of the ribs, from
which they continue as the posterior intercostal
membranes to the vertebral column. It is at
these sites created by the absence of the exter-
nal intercostal muscles anteriorly, and the
absence of the internal intercostal muscles
posteriorly, that most spontaneous thoracic
lung herniations occur.
Approximately 264 cases of lung herniation
have been reported in the literature.2 3Ofthese,
an estimated 52% were post-traumatic, 18%
were congenital, and 29% were spontaneous.24
Of 11 spontaneous hernias reported by Hiscoe
and Digman, eight were cervical and three
thoracic.4 They contrasted their findings to

Spontaneous hernias have resulted from a

emphysema, pertussus, straining during la-
bour, heavy lifting, and blowing glass or musi-
cal instruments.5 6 The mechanism of sponta-
neous lung herniation in chronic bronchitis
and emphysema is thought to be related to lung
hyperinflation, refractory cough, and possibly
weakness.27 Spontaneous hernias have also
been described in patients with congenital
absence of chest wall musculature.6 Only one
other case of spontaneous herniation of a lung
bulla has been described. This occurred in the
cervical region of a 60-year-old woman with
presents clinically as the acute onset of a focal
bulge associated with pain. Less commonly, a
patient may present with progressive painless
enlargement of a lump in the neck or between
the ribs. Frequently there will be an increase in
the size of the lung hernia with Valsalva
manoeuvre. The hernial orifice is said to be
easy to palpate and one can reduce the hernia
by covering the orifice with the fingers.6 Diag-
nosis is usually evident clinically due to the
size of the spongy mass with
manoeuvres that change intrathoracic pres-
sure, as in the case ofour patient. Confirmation
ofthe diagnosis can be accomplished with plain
chest radiography utilising a tangential projec-
tion. Limited CT of the chest with Valsalva
hernia, but should be reserved for patients in
whom the clinical or plain radiographic fea-
tures are not conclusive.
Extrathoracic herniation of lung tissue is
usually non-life-threatening and does not typi-
cally require major therapeutic interventional
procedures. Out-patient management schemes
include strapping the hernia site with compres-
sive pads or by using a thoracic corset. Surgery
should be considered when the hernia is caus-
ing chronic chest pain,9 '° incarcerates the pul-
